Conveying belt mechanism capable of achieving both asynchronous running and synchronous transition

Abstract

The invention provides a conveying belt mechanism capable of achieving both asynchronous running and synchronous transition. The conveying belt mechanism comprises an upstream section of conveying belts and a downstream section of conveying belts, wherein driven belt wheels of the two sections of conveying belts are provided with a common shaft. Overrunning clutches are connected between the driven belt wheels of at least one section of conveying belts and the common shaft. Torque can only be transmitted to the driven belt wheels of the upstream conveying belts from the common shaft in the single direction or the torque can only be transmitted to the common shaft from the driven belt wheels of the downstream conveying belts in the single direction. According to the conveying belt mechanism, no complex electromechanical control technology is needed, only starting and stopping of the upstream section of conveying belts and the downstream section of conveying belts need to be simply controlled, and therefore it can be ensured that the two sections of conveying belts are kept running synchronously in the process of transition of workpieces from the upstream conveying belts to the downstream conveying belts under the condition that the downstream conveying belts are started and stopped frequently. The conveying belt mechanism is wide in application range and capable of being widely used for various machining devices or production lines of tile film spreading machines, tile packaging machines and the like.

Description

technical field [0001] The present invention relates to conveyor belt mechanisms for conveying workpieces. Background technique [0002] In various production lines and processing equipment, it is often necessary to relay workpieces with multi-section conveyor belts. A requirement that is often encountered is that when the downstream conveyor belt is stopped, the adjacent upstream conveyor belt is required to run independently, and when the workpiece reaches the transition position between the upstream conveyor belt and the downstream conveyor belt, the downstream conveyor belt and the upstream conveyor belt are required to remain strictly. The synchronous operation of the conveyor belt requires both the upstream and downstream conveyor belts to be able to run asynchronously and transition synchronously. [0003] In order to realize the above functions, the prior art adopts a control mode in which two motors drive the upper and lower conveyor belts respectively. When the d...

Problems solved by technology

However, since the upper and lower conveyor belts need to run frequently asynchronously, even if two motors of the same model and specification are used, it is difficult to control the two conveyor belts to maintain strict synchronous operation during the transition of workpieces, resulting in workpieces being in the process of conveying The position error generated in the machine cannot meet the high requirements of workpiece transmission
