Home >> Rejection systems

On all production lines, quality is more than an indispensable requirement. Rejection systems are necessary to achieve said quality. Not all products are suitable for sale on the market. Moreover, it is estimated that 2% of the final product are rejected units. There are many reasons why a product may be rejected, which is why E2M COUTH always offers the best systems to help improve your production.

Why are rejection systems necessary?

Products are made at all factories or in all industries that do not have the best characteristics to reach the end shelf and for a client to purchase it. There are many possible reasons, from receiving a blow, an error in labelling, to other problems that may arise.

With the rejection systems available at E2M COUTH, the mission to dispose of products that do not meet the defined quality standards is much simpler. It is true that some products can be rejected just by looking at them, but there are also other factors, such as defects in caps, lids, and labels, or because the printed codes are incorrect.

These latter factors cannot be detected by the human eye. They need the aid of technology in smart artificial vision inspection systems for proper classification, then a rejection system with our solutions.

Types of rejection systems available at E2M COUTH

At E2M COUTH, we always want the best and most cutting-edge technology to help you to improve your production. This is why we know that rejection systems are a key part, since they will help you to ensure that all the products sold boast the right quality.

To this end, E2M COUTH offers three different rejection systems. Each one of them can be applied to different kinds of industries. They are:


Push rejection

Push rejection systems use a pneumatic compressed air cylinder and a plate mounted on a piston shaft. When a product must be rejected, the inspection system’s control software gives the order for the system’s pneumatic cylinder to activate with compressed air, and the plate located at the end of the piston is responsible for removing said article from the conveyor belt, pushing it off it.

This type of rejection system is perfect for products whose weight is between average and high, with uniform orientation and separation on a narrow conveyor belt.

These rejection systems may be located at the end of the production line, although they can also be placed at the beginning phases of the process.


Gentle deviation rejection systems

In this case, gentle deviation systems are designed to remove products from the production line by deviating them to another lane. In this regard, when the sensor detects any anomalies, the rejection system will gently deviate the product to another zone on the production line for review.

This type of rejection system is used with vision devices and is the perfect complement to remove articles that are not ready for sale. This is fluid rejection at all times and is perfect for delicate products.

If you have production that operates at high speed, what you can do is incorporate a double sweep action so that products can be removed from both sides of the conveyor belt.


Gentle push rejection systems

Gentle push rejection systems generally have a cushioned roller, which is activated by compressed air and is designed to remove products from the production line gently. Moreover, you need not worry about the product’s size, since it can be adjusted to the dimensions of each item to make removal fast and fluid.

Advantages of a rejection system on a production line

Now you know what a rejection system on a production line consists of. These kinds of devices have a series of advantages that will positively affect the manufacture process of items. They are:



The rejection systems available at E2M COUTH have a high degree of adaptability to any production line. Depending on the products you are manufacturing, you may decide on one system or another. They can adapt to the width of the conveyor belt, as well as the speed and shape of the product.


Fast and

The rejection systems we have available are capable of working at high speeds. Many times, production lines operate at a high speed because of the products being made. In this case, our systems are capable of analysing these products to perfection to guarantee that they are in proper condition.


You will save time and money

We know that defects can occur on a production line. Our systems are there to detect them. In this regard, you can see which kinds of defects repeat the most often and apply a remedy in the production line phase where said problem occurs the most. With our inspection systems, you can detect common defects. This will make your production improve, saving you time and money by detecting possible defects.



One of the great advantages of the rejection systems we have available at E2M COUTH is that they were designed with materials that make them very easy to clean.
