Description

A multi-station reciprocating conveyor

technical field

The invention belongs to the technical field of conveying equipment, and relates to a multi-station reciprocating conveyor.

Background technique

Robot technology integrates multidisciplinary technology, covers a wide range, and has applications in many fields. Because it replaces manual operations, effectively reduces the intensity of manual operations, and greatly improves work efficiency, it has been widely accepted by many industries. Attention, and set off an upsurge of robot development and application. For example, on the food packaging and conveying production line, industrial robots replace the original operators to perform product filling, packaging, inspection, palletizing and other work. In order to make the robot production line work more accurately, efficiently and continuously, peripheral equipment supporting the robot is also essential, such as conveyors, AGVs, packaging machines, weighing machines, etc.

When multiple robots are working together, the loading and unloading of workpieces is the key. The positioning accuracy of the loading and unloading station affects the accuracy of the robot's work on the workpiece, and the speed and stability of the conveyor affect the process and working hours of the entire line. Therefore, the multi-station high-precision and high-speed conveyor is a necessary factor for the successful operation of a multi-robot production line. Therefore, the development of multi-station high-precision and high-speed conveyor will be the focus of the next research.

Groups of mobile vehicles work alternately.

Wherein, when the first mobile carrier moves to the starting end and the second mobile carrier moves to the terminal end at the same time, the two groups of mobile carriers meet in the middle, because the suction cup fixing plate and the object bearing plate in the second mobile carrier are The cylinder is jacked up so that the carton is also at a higher position, so the first mobile carrier can pass through the lower part of the carton in the second mobile carrier and return to the starting end, so that the two groups of mobile carriers do not interfere with each other.

Compared with the prior art, the present invention has the following characteristics:

1) The two groups of mobile vehicles work alternately without interfering with each other, making full use of the idle time during which the mobile vehicles return from the termination end to the start end, greatly improving work efficiency;

2) It adopts servo motor control, and adjusts the moving speed and stop position of the mobile carrier through the reducer. The conveying speed is fast and the positioning accuracy is high, which can reach 0.05mm. It is suitable for loading and unloading transfer of small and medium-sized workpiece materials;

3) The structure is compact, and the transportation of carton packaging products of different weights and sizes can be satisfied by changing the mobile carrier, and the carrying capacity and working efficiency of the conveyor can be improved by increasing the number of mobile carriers and linear modules, which is flexible Good performance and easy maintenance.
