Conveyor and control method

Abstract

The invention relates to a conveyor and a control method. The conveyor comprises an input passage, an output passage, at least two buffer conveying passages and a switcher, each buffer conveying passage is provided with an inlet and an outlet, all the inlets are arranged in parallel, and all the outlets are arranged in parallel, and the switcher is used for switching the input passage to be docked with any one of the inlets and switching the output passage to be docked with any one of the outlets. Mutual squeezing among products and squeezing between the products and the conveyor are avoided effectively, deformation and damage to the products due to squeezing force are avoided, product qualified rate is increased, buffer capacity is determined, and start and stop of an entire conveying system can be controlled accurately.

Description

technical field [0001] The invention belongs to the field of operation and transportation, and in particular relates to a conveying device and a control method. Background technique [0002] During the production, the bottles processed by the previous equipment need to be sent to the next equipment for processing. Because the production process of each process is not synchronized, and the bottles sent by the front end cannot be sent away in time due to the back-end equipment failure, shutdown and other reasons. , resulting in production stagnation and losses. In this regard, the existing bottle chain generally adopts the method of setting a bottle storage platform, such as figure 1 As shown, the bottles that cannot be sent away in time can be accumulated on the bottle storage platform 500, so as to alleviate the blockage of some bottles. [0003] However, the bottle storage platform only has the guide plate on the edge as a guide. When the forward direction is blocked, the...

Problems solved by technology

[0003] However, this bottle storage platform only has the guide plate on the edge as a guide. When the forward direction is blocked, the bottles will be blocked and accumulated at the output port, and the input chain will continuously send bottles, and the subsequent bottles will collide with the accumulated bottles. pressure, causing the bottles to spread along both sides of the stacking place until the entire platform is full of bottles, and the input chain will stop. The greater the pressure of the bottle, the bottle whose front end is in contact with the guide plate has the highest pressure

With the enlargement and growth of the platform and the accumulation of more and more bottles, this pressure will also increase, and these pressures will always cause the surface of the bottle to be scratched or scratched, or the shape of the bottle will be deformed, which will seriously damage the bottle. Become waste products, seriously affecting production efficiency and increasing production costs

[0004] In addition, the bottles move passively on the platform and squeeze and collide with each other, their trajectory is uncertain, and due to the limitation of mutual extrusion, the entire bottle storage section is often unable to be completely filled and then forced to stop

Therefore, this method cannot truly determine the capacity of the bottle storage platform that can actually store bottles, cannot accurately determine the full load moment of the bottle storage section, and cannot precisely control when to stop feeding bottles into the bottle storage platform, resulting in more serious conflicts between the bottles. extrusion
