Automatic carrying system based on AGVs and multi-AGV cooperation method

Abstract

The invention discloses an automatic carrying system based on AGVs and a multi-AGV cooperation method, and belongs to the technical field of carrying trolleys. The automatic carrying system comprisesan AGV carrier main body, driving wheels are arranged on a lower chassis of the AGV carrier main body, a carrying platform is arranged on the side, in the advancing direction, of the AGV carrier mainbody, and suspension wheels are arranged at the positions, corresponding to the driving wheels, of the lower portion of the AGV carrier main body. According to the arrangement, through mutual cooperation of designed structures such as a first buffer spring, a second buffer spring, a first hydraulic cylinder, a sliding block, a sliding groove, a second hydraulic cylinder, and a buffer device, the distance complementary effect is achieved, so that the stability of a carrying goods table in the pushing advancing process of the AGV carrier main body can be improved, therefore, materials or finished products on a buffer table are prevented from toppling forwards under the action of inertia, smooth operation of the AGV carrier main body is guaranteed, the material distribution efficiency of semi-finished products is improved, and meanwhile idle waste of equipment is avoided.

Description

technical field [0001] The invention belongs to the technical field of handling trolleys, and in particular relates to an AGV-based automatic handling system and a multi-AGV cooperation method. Background technique [0002] AGV (automated guided vehicle) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions. AGV is a wheeled In the category of mobile robots, trucks that do not require a driver in industrial applications use rechargeable batteries as their power source. Generally, they can control their travel routes and behaviors through computers, or use electromagnetic tracks to set up their travel routes. Electromagnetic tracks Pasted on the floor, the unmanned transport vehicle is a transport vehicle that moves and operates according to the electromagnetic track. [0003] AGV-based automatic handling equipment has...

Problems solved by technology

[0003] AGV-based automatic handling equipment has gradually become the standard auxiliary equipment required for the distribution of raw materials and the transfer of finished or semi-finished products within the factory. However, the currently used AGV-based automatic handling equipment usually requires Set the shock absorbing mechanism, for example, Chinese utility model patent CN209972626U discloses an AGV trolley, including the AGV trolley body, the bottom of one side of the AGV trolley body is fixedly installed with an obstacle buffer plate, and the two sides of the top of the buffer plate are fixedly installed with reinforcement plates , the middle part of the top of the AGV body is fixed with a shock-absorbing base, the shock-absorbing base includes stitches, a wooden bottom plate, a shock-absorbing spring and a sponge layer, and the two sides of the top of the AGV body are fixed with folding plates, two The folding boards all include a first panel and a second panel. The beneficial effect of the utility model is that the folding board is provided, and the second panel is folded relative to the first panel through the forward and reverse motor, so that the AGV trolley body forms two The item storage space is convenient for storing different types of items. It is equipped with a shock-absorbing base. During the process of moving items, because the shock-absorbing base is equipped with a shock-absorbing spring and a sponge layer, the friction on the bearing surface is improved to avoid During the transportation process, the inertia of the movement causes the items to fall off and cause damage. Although the above background technology has effectively improved the stability of the automatic handling equipment, due to the limited detection range and self-response ability of the automatic handling equipment, it is necessary to emergency Parking, and due to the large amount of production carried by the automatic handling equipment, it is easily affected by inertia, and it is easy to cause the product to fall off, and in serious cases, it will be dumped, and because there are many internal production lines in the factory, a large amount is usually added to meet the production needs. Automatic handling equipment to achieve one-to-one or one-to-many handling, but because the working conditions of each production line are evenly distributed, the workload of each automatic handling equipment is different, so multiple automatic handling equipment in a large factory building How to work together is an urgent problem in this field
