Lifting device of stacker crane

Abstract

The lifting device is used for driving a clamp for clamping stacked materials to ascend and descend and comprises a walking frame arranged above the clamp, a lifting channel is arranged in the middle of the walking frame, lifting shaft frames are slidably connected to the inner walls of the two sides of the lifting channel, and the lower ends of the lifting shaft frames are fixed to the clamp through connecting pieces. The lifting device further comprises a gear rack mechanism and a gear motor which drive the lifting shaft frame to move up and down, the gear rack mechanism comprises a rack arranged on the front end face of the lifting shaft frame and extending in the extending direction of the lifting shaft frame and a gear meshed with the rack, and the gear motor is fixed to the walking frame and used for driving the gear to rotate. The output end of the air cylinder is connected with a piston rod, and the lower end of the piston rod is connected with the lifting shaft frame through a floating connector. In this way, the lifting capacity and speed range are wide, energy is saved, efficiency is high, the structure is simple, and the requirement for timely stacking of materials in the medium-high-yield production process can be met.

Description

technical field [0001] The invention relates to the technical field of automatic stacking, and more specifically, to a lifting device of a palletizer. Background technique [0002] At present, when stacking and grabbing heavy-duty materials, in order to achieve the purpose of energy saving, the method of reducing the power of the deceleration motor of the lifting mechanism of the palletizer is generally adopted, and the lifting mechanism of the counterweight type is usually used, or only the cylinder is used. for promotion. These lifting mechanisms not only have limited lifting capacity and speed, high energy consumption, but also have problems such as complex structure, high failure rate, low degree of automation, limited range of use and equipment layout, etc., which cannot meet the needs of materials in the middle and high output production process The need for timely stacking. [0003] Therefore, how to solve the problems that the existing lifting mechanism not only ha...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a lifting device for a palletizer to solve the problem that the existing lifting mechanism not only has limited lifting capacity and speed, and consumes a lot of energy, but also has complex structure, high failure rate, low degree of automation, scope of use and equipment layout. There are limitations and other problems, and it cannot meet the needs of timely stacking of materials in the middle and high-volume production process
