This is why cartoning machine detection\u00a0is not just a technical option. It is a practical way to protect every carton before it becomes a finished product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A good<a href=\"https:\/\/ruidapacking.com\/fa\/cartoning-machine\/\"> automatic <strong>cartoner machine<\/strong><\/a>\u00a0should not simply open a carton and push products inside. It should know whether the product is ready, whether the quantity is correct, whether the leaflet has been fed and folded, whether the carton is formed, and whether the final flap is inserted properly. When these signals are connected with automatic rejection\u00a0or machine stop logic, photoelectric eye detection\u00a0helps reduce empty cartons, missing leaflet problems, wrong quantity loading and bad carton sealing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article explains how photoelectric eye detection\u00a0works on a cartoner machine\u00a0from material feeding to finished carton outlet. Instead of listing sensors one by one, it focuses on real production questions: how photoelectric eye detection prevents missing products in cartoning machine operation, why a cartoning machine rejects cartons with missing leaflet or product, and how cartoning machine detection reduces empty cartons\u00a0before they reach the market.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-1-Products-of-the-cartoning-machine.jpg\" alt=\"Products of the cartoning machine\" class=\"wp-image-17068\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-1-Products-of-the-cartoning-machine.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-1-Products-of-the-cartoning-machine-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-1-Products-of-the-cartoning-machine-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-1-Products-of-the-cartoning-machine-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 1 Products of the cartoning machine<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\u0646\u06a9\u0627\u062a \u06a9\u0644\u06cc\u062f\u06cc<\/strong><strong><\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reliable cartoning machine detection\u00a0should check both process status and final carton result, not only one single position at the end of the line.<\/li>\n\n\n\n<li><strong>Photoelectric eye detection<\/strong>\u00a0can monitor material supply, product quantity, leaflet stock, leaflet feeding, leaflet folding, carton forming, in-carton leaflet placement and final <strong>flap insertion<\/strong>.<\/li>\n\n\n\n<li>The best rejection logic depends on the problem.

Why Cartoning Errors Become a Real Production Cost<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1.1 Missing products do not only waste cartons<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For a production supervisor , a rejected carton is easy to see. The hidden cost behind it is usually larger. If a carton is missing products or a leaflet, operators need to stop, check, record, rework or discard materials. In regulated production, the problem can also affect batch documentation and final quality review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why many buyers search for cartoning machine detection\u00a0before choosing new equipment. They are not only asking whether the machine can run fast. They want to know whether the machine can detect wrong quantity, missing products and leaflet errors before defective cartons leave the line.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1.2 Detection should control both process and final result<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A cartoning machine\u00a0has many connected steps: feeding, leaflet folding, carton suction, carton forming, product pushing, flap insertion\u00a0and final rejection. If inspection only happens at the final outlet, the machine may already have wasted cartons, leaflets and products before the defect is found.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A better cartoning machine inspection system\u00a0combines process detection and result detection. Process detection checks whether the next action should happen. Result detection checks whether the expected action has been completed. This is the logic behind photoelectric eye detection for leaflet and carton inspection.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-2-Unqualified-products-of-the-cartoning-machine.jpg\" alt=\"Unqualified products of the cartoning machine\" class=\"wp-image-17064\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-2-Unqualified-products-of-the-cartoning-machine.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-2-Unqualified-products-of-the-cartoning-machine-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-2-Unqualified-products-of-the-cartoning-machine-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-2-Unqualified-products-of-the-cartoning-machine-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 2 Unqualified products of the cartoning machine<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>2. How <\/strong><strong>Photoelectric Eye Detection<\/strong><strong>&nbsp;Works on a <\/strong><strong>\u0633\u06cc<\/strong><strong>artoner <\/strong><strong>\u0645<\/strong><strong>achine<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2.1 <\/strong><strong>\u0686\u0634\u0645 \u0641\u0648\u062a\u0648\u0627\u0644\u06a9\u062a\u0631\u06cc\u06a9<\/strong><strong>s create a step-by-step inspection logic<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Photoelectric eye detection\u00a0is used to identify whether a product, leaflet or carton has reached a required position. On a horizontal cartoning machine, these signals are linked with the PLC and motion control system, so the machine can decide whether to feed, push, stop, alarm or reject.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if the product is not ready, the machine should not continue to feed cartons. If the carton is not formed, the machine should stop to avoid a mechanical jam. If the leaflet is missing but the carton has already completed the cycle, the final carton should be rejected. The value of an <strong>inspection system<\/strong>&nbsp;is not only seeing the error, but responding to it correctly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2.2 Detection and <\/strong><strong>automatic rejection<\/strong><strong>&nbsp;should work together<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Detection alone is not enough. If the machine finds an abnormal condition but still allows the carton to pass, the sensor has not solved the production problem. If every small error causes a full stop, the line may lose too much efficiency. The right solution is to match each detection point with the correct action.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some issues should lead to automatic rejection, such as missing product detection, wrong quantity, missing leaflet in a completed carton or poor flap insertion. Some issues should stop the machine, such as carton forming failure, because pushing products into an unformed carton can damage the product or the mechanism. This balance is what makes cartoning machine detection\u00a0useful in real production.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-3-Photoelectric-eye-detection-on-the-cartoning-machine.jpg\" alt=\"Photoelectric eye detection on the cartoning machine\" class=\"wp-image-17065\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-3-Photoelectric-eye-detection-on-the-cartoning-machine.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-3-Photoelectric-eye-detection-on-the-cartoning-machine-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-3-Photoelectric-eye-detection-on-the-cartoning-machine-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-3-Photoelectric-eye-detection-on-the-cartoning-machine-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 3 Photoelectric eye detection on the cartoning machine<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>3. Product Feeding Detection: Prevent Overfill, Shortage and Wrong Quantity<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3.1 Upper <\/strong><strong>photoelectric eye<\/strong><strong>&nbsp;in the feeding silo<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The feeding silo is where cartoning errors can begin. The upper <strong>photoelectric eye<\/strong>&nbsp;detects whether the silo has reached a full condition. When the silo is full, products coming from the previous connected equipment should not continue entering the cartoning area. They can be rejected or controlled by the upstream line to avoid over-accumulation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This upper photoelectric eye\u00a0protects feeding stability before the actual cartoning step begins. Without this control, excess products may disturb the feeding rhythm.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3.2 Lower <\/strong><strong>photoelectric eye<\/strong><strong>&nbsp;in the feeding silo<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The lower photoelectric eye\u00a0monitors whether the material level has reached the refill condition. When the detection logic shows that the silo needs more product, the upstream connected line can continue feeding. This helps keep the product supply within a usable range, instead of switching between too full and too empty.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Together, the upper and lower photoelectric eyes make product feeding more controlled. Stable feeding is a prerequisite for the continuous operation of the machine.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3.3 Material in-place and quantity detection<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After products enter the conveyor, the next question is whether the product group reaches the set quantity, height or position. The material in-place and quantity detection photoelectric eye\u00a0checks whether the product is ready before it moves to the pushing area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the product is missing, excessive or not in the correct position, the whole material group should be rejected directly. This is the practical <strong>no product no carton<\/strong>\u00a0logic that prevents wasting empty cartons. This <strong>missing product detection<\/strong>\u00a0logic is important for <a href=\"https:\/\/ruidapacking.com\/fa\/what-is-a-blister-pack\/\">blister packs<\/a>, bottles, sachets, tubes and other products that must be loaded in a fixed quantity. It also helps explain how cartoning machine detection reduces <strong>empty cartons<\/strong>\u00a0in daily production.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-4-Material-in-place-and-quantity-detection1.jpg\" alt=\"Material in-place and quantity detection(1)\" class=\"wp-image-17066\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-4-Material-in-place-and-quantity-detection1.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-4-Material-in-place-and-quantity-detection1-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-4-Material-in-place-and-quantity-detection1-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-4-Material-in-place-and-quantity-detection1-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 4 Material in-place and quantity detection<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>4. <\/strong><strong>Leaflet Detection<\/strong><strong>: Avoid Missing Manuals and Folding Problems<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4.1 Low leaflet stock detection<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A cartoning line can run mechanically well but still produce non-conforming cartons if the instruction leaflet supply is too low. The leaflet stock detection photoelectric eye\u00a0checks whether there are enough leaflets in the leaflet folding machine. When the leaflet stock is low, the system reminds operators to add instruction manuals in time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This part of <strong>leaflet detection<\/strong>&nbsp;is simple but valuable. It helps prevent missing leaflet problems before the folding station runs out of paper and before defective cartons are produced continuously.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4.2 <\/strong><strong>Leaflet feeding detection<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The next inspection point checks whether the instruction leaflet is fed smoothly. A leaflet may fail to separate, slip, bend or move late. Leaflet feeding detection\u00a0helps confirm whether the paper has been released and transferred correctly before folding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For buyers asking <strong>how to prevent missing leaflet in automatic cartoning machine<\/strong>&nbsp;operation, this is one of the first detection points to check. If leaflet feeding is unstable, later carton rejection may increase even when the product feeding side is normal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4.3 <\/strong><strong>Leaflet <\/strong><strong>in-position<\/strong><strong>&nbsp;detection<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Leaflet folding detection<\/strong>&nbsp;checks whether the instruction leaflet has been folded correctly. If this position detects that there is no leaflet, but the product has already arrived normally, the carton feeding and pushing action can still continue. The product enters the carton as usual, and the complete carton is rejected at the final finished-product outlet because the leaflet is missing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This logic is different from simply stopping the machine immediately, but it is useful in real operation. It avoids creating a jam at the pushing area while still preventing a carton without a leaflet from becoming an accepted finished product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4.4 <\/strong><strong>In-carton leaflet detection<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In-carton leaflet detection\u00a0confirms whether the leaflet enters the carton together with the product. A leaflet may get stuck before insertion if the transfer is not smooth. During insertion, correct positioning helps prevent the leaflet from being pushed crookedly or left outside the carton.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This inspection point is important because a finished carton can look normal from the outside while still missing the leaflet inside. A reliable carton inspection system\u00a0should therefore verify the inside result, not only the external carton appearance.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-5-Leaflet-stock-detection.jpg\" alt=\"Leaflet stock detection\" class=\"wp-image-17067\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-5-Leaflet-stock-detection.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-5-Leaflet-stock-detection-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-5-Leaflet-stock-detection-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-5-Leaflet-stock-detection-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 5 Leaflet stock detection<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>5. Carton Forming and Closing Detection: Stop Bad Cartons Before Shipping<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5.1 <\/strong><strong>Carton forming detection<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Carton forming detection\u00a0checks whether the carton has been opened and formed correctly. If the carton does not stand up or fails to form, the cartoner machine\u00a0should stop. This prevents the push rod from sending products into an unformed carton and avoids damage to both products and machine parts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is one case where stopping the machine is better than waiting for <strong>automatic rejection<\/strong>\u00a0later. If the carton is not formed, the mechanical path itself may become unsafe for stable pushing. Carton forming detection\u00a0protects the next action before it happens.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-6-Carton-forming-detection.jpg\" alt=\"Carton forming detection\" class=\"wp-image-17060\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-6-Carton-forming-detection.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-6-Carton-forming-detection-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-6-Carton-forming-detection-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-6-Carton-forming-detection-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 6 Carton forming detection<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5.2 <\/strong><strong>\u0641<\/strong><strong>lap insertion<\/strong><strong>&nbsp;and horizontal level detection<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Even after the product and leaflet enter the carton, the finished box can still fail at the closing stage.

If no metal signal is detected, the system can judge that there may be no blister product inside the carton and reject it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This answers a practical question: how metal detection checks blister packs inside cartons. It does not replace all other product checks, but it adds a useful verification layer when the packed product contains aluminum foil.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>6.2 When <\/strong><strong>metal detection<\/strong><strong>&nbsp;should be combined with other inspection points<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Metal detection\u00a0is not suitable as the only method for every cartoning product. Bottles, sachets, tubes or non-metal packages may require other detection logic. For this reason, metal detection\u00a0should be combined with product quantity detection, leaflet detection, carton forming detection\u00a0and flap insertion\u00a0detection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A reliable cartoning machine inspection system\u00a0should match the product form. If the carton contains blister packs, metal detection\u00a0can be valuable. If the carton contains a plastic bottle or sachet, the machine should rely more on position, quantity, height or presence detection.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-8-Metal-detection.jpg\" alt=\"Metal detection\" class=\"wp-image-17062\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-8-Metal-detection.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-8-Metal-detection-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-8-Metal-detection-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-8-Metal-detection-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 8 Metal detection<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>7<\/strong><strong>.

The machine is designed for pharmaceuticals, health supplements, food, medical equipment and other products that require fast and accurate cartoning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its inspection logic covers material feeding, material quantity qualification, instruction manual inspection, instruction manual in-place detection, carton forming position detection, instruction carton inspection, flap insertion\u00a0protection, carton flap horizontal level detection\u00a0and metal detection. The goal is to reduce missing products, missing leaflet, wrong loading, bad carton forming and poor flap insertion\u00a0before finished cartons leave the line.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article is not saying every production line needs the same detection configuration. The better approach is to start from your real problem: missing products, leaflet errors, empty cartons, unformed cartons, poor flap insertion\u00a0or blister packs missing from cartons. Then choose a cartoning machine inspection system\u00a0that matches your product and rejection logic.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"540\" src=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-9-RQ-ZH-320W-Horizontal-Cartoning-Machine.jpg\" alt=\"RQ-ZH-320W Horizontal Cartoning Machine\" class=\"wp-image-17063\" srcset=\"https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-9-RQ-ZH-320W-Horizontal-Cartoning-Machine.jpg 960w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-9-RQ-ZH-320W-Horizontal-Cartoning-Machine-300x169.jpg 300w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-9-RQ-ZH-320W-Horizontal-Cartoning-Machine-768x432.jpg 768w, https:\/\/ruidapacking.com\/wp-content\/uploads\/2026\/06\/Figure-9-RQ-ZH-320W-Horizontal-Cartoning-Machine-18x10.jpg 18w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Figure 9 RQ-ZH-320W&nbsp;Horizontal Cartoning Machine<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\u0633\u0648\u0627\u0644\u0627\u062a \u0645\u062a\u062f\u0627\u0648\u0644<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1<\/strong><strong>.<\/strong><strong>&nbsp;What is <\/strong><strong>photoelectric eye detection<\/strong><strong>&nbsp;on a <\/strong><strong>\u062f\u0633\u062a\u06af\u0627\u0647 \u06a9\u0627\u0631\u062a\u0646 \u0633\u0627\u0632\u06cc<\/strong><strong>?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Photoelectric eye detection\u00a0uses sensors to check whether products, leaflets or cartons are present at required positions. On a cartoner machine, these signals help control feeding, pushing, carton forming, leaflet handling, rejection and machine stop logic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2<\/strong><strong>.<\/strong><strong>&nbsp;Can a <\/strong><strong>cartoner machine<\/strong><strong>&nbsp;stop <\/strong><strong>feeding cartons<\/strong><strong>&nbsp;when there is no <\/strong><strong>product<\/strong><strong>?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. A properly designed cartoning machine no product\u00a0no carton\u00a0function\u00a0can prevent wasting carton. This helps avoid material waste.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3<\/strong><strong>.<\/strong><strong>&nbsp;What happens if the product is present but the leaflet is missing?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the product has arrived normally but <strong>leaflet folding detection<\/strong>&nbsp;finds no leaflet, the machine can still complete the carton cycle and reject the whole finished carton at the outlet. This prevents a carton without an instruction leaflet from becoming an accepted product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4<\/strong><strong>.<\/strong><strong>&nbsp;How does a <\/strong><strong>\u062f\u0633\u062a\u06af\u0627\u0647 \u06a9\u0627\u0631\u062a\u0646 \u0633\u0627\u0632\u06cc<\/strong><strong>&nbsp;detect wrong product quantity?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A material in-place or quantity detection <strong>photoelectric eye<\/strong>&nbsp;checks whether the product group reaches the set quantity, height or position. If the product is missing, excessive or not in place, the material group can be rejected directly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5<\/strong><strong>.<\/strong><strong>&nbsp;Why does <\/strong><strong>carton forming detection<\/strong><strong>&nbsp;sometimes stop the machine?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the carton does not stand up or form correctly, pushing products forward may damage the product or cause a mechanical jam. In this case, <strong>carton forming detection<\/strong>&nbsp;should stop the machine instead of waiting for final rejection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>6<\/strong><strong>.<\/strong><strong>&nbsp;Why are two <\/strong><strong>flap insertion<\/strong><strong>&nbsp;detection<\/strong><strong>&nbsp;sensors used at the final outlet?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Two sensors can check the left and right sides of the finished carton. If either carton tongue or flap is not inserted correctly, the carton can be rejected to avoid poor carton sealing quality.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>7.<\/strong><strong>&nbsp;What information should be prepared before choosing a <\/strong><strong>cartoning machine inspection system<\/strong><strong>?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Prepare your product type, carton size, leaflet size and folding method, required quantity per carton, feeding method, carton closing style and rejection requirements. These details help determine the correct cartoning machine detection\u00a0points.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>References<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">[1] Marchesini Group<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.marchesini.com\/en\/machines-lines\/vision-systems-for-cartoners\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/www.marchesini.com\/en\/machines-lines\/vision-systems-for-cartoners<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[2] Uhlmann<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.uhlmann.de\/en\/products-and-solutions\/cartoners\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/www.uhlmann.de\/en\/products-and-solutions\/cartoners<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[3] Syntegon<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.syntegon.com\/solutions\/food\/cartoning-machine\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/www.syntegon.com\/solutions\/food\/cartoning-machine<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[4] IMA<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pharmaceuticalonline.com\/doc\/ima-a94-continuous-motion-horizontal-cartonin-0001\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/www.pharmaceuticalonline.com\/doc\/ima-a94-continuous-motion-horizontal-cartonin-0001<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Learn how photoelectric eye detection help prevent missing products, missing leaflets, unformed cartons and poor flap insertion in automatic cartoning lines.<\/p>","protected":false},"author":4,"featured_media":17068,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_sitemap_exclude":false,"_sitemap_priority":"","_sitemap_frequency":"","footnotes":""},"categories":[35],"tags":[106],"class_list":["post-17058","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","tag-cartoning-machine"],"acf":[],"_links":{"self":[{"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/posts\/17058","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/comments?post=17058"}],"version-history":[{"count":5,"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/posts\/17058\/revisions"}],"predecessor-version":[{"id":17073,"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/posts\/17058\/revisions\/17073"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/media\/17068"}],"wp:attachment":[{"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/media?parent=17058"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/categories?post=17058"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ruidapacking.com\/fa\/wp-json\/wp\/v2\/tags?post=17058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
