Blocking and positioning device for buffer type conveyor

Abstract

The invention relates to a blocking and positioning device for a buffer type conveyor. The device is formed in the manner that two sets of blocking and positioning mechanisms are correspondingly connected with a synchronous rotation interlocking transmission mechanism. The blocking and positioning mechanisms comprise rotation supports, rotation shaft sleeves, rotation shafts, blocking wheels, positioning plug pins, compression springs, positioning sleeves, blocking pieces and reversing drive rods. The synchronous rotation interlocking transmission mechanism ensures that the blocking and positioning mechanisms are switched during synchronous reversing and structurally comprises an installation plate, an air cylinder, an air cylinder rear lug ring support and a synchronous rotation connecting rod. According to the blocking and positioning device, a single work unit can be positioned, and conveying of multiple subsequent units is blocked; and the blocking and positioning device is simple and compact in structure, small in size and stable and accurate in positioning and has the buffer function. According to the blocking and positioning device, the air cylinder is connected with the synchronous rotation connecting rod to drive the blocking and positioning mechanisms to rotate, and positioning mechanisms and blocking mechanisms can be switched; it is ensured that one conveying unit is accurately and stably conveyed into a station, and meanwhile the subsequent units are prevented from following the corresponding conveying unit to pass the work station; and accuracy and safety of equipment operation are effectively improved.

Description

technical field [0001] The invention relates to a conveyor device, in particular to a blocking positioning device for an accumulation type conveyor. Background technique [0002] At present, there are many types of industrial conveying equipment, and conveying lines with positioning and accumulating functions have a good application prospect for automatic conveying. The BUFFER conveyor can use the friction and blocking positioning mechanism to realize the positioning and accumulation function. As one of the two core technologies, the structural design of the blocking positioning mechanism is very important. It is necessary to install a mechanism capable of positioning a single working unit and blocking subsequent multiple units in a relatively narrow space. The design should have a small, easy-to-use, durable and easy-to-remove structure; however, the existing related equipment is complex in structure and not stable enough in performance , the application effect is not good...
