[0002] The roller is the element that bears the load when the bearing is running. It is the weakest part in the roller bearing. Its manufacturing quality has a great influence on the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.) and is the main factor affecting the service life of the bearing.

[0003] After the rollers are processed, they need to be packaged and transported to the customer's factory. One way of packaging is to seal the rollers connected end to end with packaging film. Then they are coiled in a customized wooden box. In the production of tapered rollers, the direction of the rollers needs to be consistent to facilitate the subsequent processing. Therefore, the reverse material needs to be removed before the rollers enter the packaging film, and the continuity of the rollers must be maintained, and there must be no empty space in the finished product.

[0004] In the prior art, the rejection of the reversed material of the tapered roller is usually done manually, with the reversed material blocked by a mechanical mechanism, and then the reversed material is taken out manually and the equipment is restarted. This method has the following problems:

[0043] The feed conveyor belt 2 is arranged on the workbench 1, and the conveying direction of the feed conveyor belt 2 is left-right. The discharge conveyor belt 3 is arranged on the workbench 1, and the conveying direction of the discharge conveyor belt 3 is left-right, and the discharge conveyor belt 3 is located on the left side of the feed conveyor belt 2. Both the feed conveyor belt 2 and the discharge conveyor belt 3 are used to convey roller products.

[0044] The material-picking mechanism 4 is located between the feed conveyor belt 2 and the discharge conveyor belt 3.
