Double-lifting AGV

Abstract

The invention provides a double-lifting AGV. The double-lifting AGV comprises a bottom layer fixing structure, a middle layer platform and two lifting mechanisms, wherein the bottom layer fixing structure is used for being installed on the AGV; the middle layer platform is slidably arranged at the top of the bottom layer fixing structure; the two lifting mechanisms are slidably arranged on the two sides of the top of the middle layer platform correspondingly, and at least two bearing structures are arranged at the tops of the lifting mechanisms; the bearing structures on the two opposite lifting mechanisms are in one-to-one correspondence; and the corresponding bearing structures form a set of stations. The four bearing structures form the two lifting stations, two reel type goods can be lifted simultaneously, and material taking and discharging can be achieved at a time; the distance between the two lifting mechanisms can be adjusted so as to adapt to the reel type goods with different lengths, the takt is saved, and the productivity is improved; and the lifting structures are compact in structure, horizontal movement can be converted into vertical movement, the space occupancy ratio is decreased, the gravity center is lowered, and the stability of the AGV is improved.

Description

technical field [0001] The invention relates to the technical field of automatic handling of industrial products, in particular to a double-lift AGV trolley. Background technique [0002] In the production process of protective equipment such as masks, a large number of textiles such as non-woven fabrics and melt-blown fabrics are used. These textiles are usually packaged in rolls. When the output is low, these production lines usually use manual feeding and unloading. In the case of high output, manual operation is difficult to meet the demand. At the same time, manual operation is more labor-intensive and prone to safety accidents. [0003] At present, most of the AGV lifting structures on the market use screw rods and chains. The screw rod and chain transmission methods cannot be self-locking. Especially in lifting applications, it is necessary to equip a separate anti-drop mechanism. Secondly, the existing lifting structure has a short stroke. The space occupation rat...

When the output is low, these production lines usually use manual feeding and unloading. In the case of high output, manual operation is difficult to meet the demand

At the same time, manual operation is labor-intensive and prone to safety accidents

[0003] At present, most of the AGV lifting structures on the market use screw rods and chains. The screw rod and chain transmission methods cannot be self-locking. Especially in lifting applications, it is necessary to equip a separate anti-drop mechanism. Secondly, the existing lifting structure has a short stroke. The space occupation ratio is large, the structure is not compact, and it is difficult to be used in a working environment with limited space

[0004] In addition, most of the AGV trolleys in the existing technology are usually single-station, which can only be used for single feeding or unloading, so the time cycle is long and the production efficiency is low.
