Automatic sorting machines are generally composed of a conveyor mechanical part, an electrical automatic control part, and a computer information system networked together. It can automatically sort, pack, and seal cigarettes, whole boxes of cigarettes, medicines, goods, materials, etc. according to user requirements and site conditions, and perform continuous operations based on user, place name, and product name. Mechanical conveying equipment is designed and customized according to the shape, volume, and weight of the conveyed items. Sorting conveyor is one of the key equipment for factory automated three-dimensional warehouses and logistics distribution centers to classify and organize logistics. By applying sorting systems, accurate and efficient work can be achieved in logistics centers.

Sorting machines are classified into different types according to their sorting mechanism structure, and the common main types are as follows:

1. Barrier type sorting machine

The baffle sorting machine uses a baffle (stopper rod) to block the goods moving forward on the conveyor and guide them to the slide on one side for discharge. Another form of baffle is that one end of the baffle serves as a fulcrum and can rotate. When the baffle is in motion, it blocks the forward movement of the goods like a wall, and uses the frictional force of the conveyor to push the goods, causing them to move along the surface of the baffle and be discharged from the main conveyor to the slide. Normally, the baffle is located on one side of the main conveyor, which allows the goods to continue moving forward; If the baffle moves or rotates laterally, the goods will be directed towards the slide.

The baffle is usually installed on both sides of the conveyor, not in contact with the flat surface of the conveyor. Even during operation, it only contacts the goods and does not touch the conveying surface of the conveyor. Therefore, it is suitable for most forms of conveyors. As for the baffle itself, there are also different forms, such as linear, curved, and some with rollers or smooth plastic materials installed on the baffle working surface to reduce frictional resistance.

2. Floating sorting machine

Floating sorting machine is a structural form that lifts goods from the main conveyor and guides them out of the main conveyor. From the direction of the main conveyor, one is that the direction of the lead out forms a right angle with the main conveyor; Another way is to form a certain angle (usually 30 ° -45 °). Generally, the former has lower productivity than the latter and is more likely to have a greater impact on the product.

There are roughly several forms of floating sorting machines:

(1) Tape floating sorting machine, as shown in the picture. This sorting structure is used on roller type main conveyors, where two or more powered adhesive tapes or a single chain are installed horizontally below the main conveyor rollers. When the sorting machine structure receives the command to start, the tape or chain lifts upwards, contacts the bottom of the product to lift it up, and moves it out towards the main conveyor side.

(2) Roller floating sorting machine, as shown in the figure. This sorting mechanism is used on roller or chain type main conveyors, where one or dozens of powered inclined rollers are installed below the surface of the main conveyor? When the sorting mechanism is started, the inclined rollers float upwards, touching the bottom of the goods and moving them diagonally out of the main conveyor. One type of upward sorting machine uses a row of rollers that can rotate left or right to lift the goods and discharge them to the left or right.
