Top end braking method for aisle stacker

Abstract

According to a top end braking method of an aisle stacker, which is provided by the invention, different friction modes of a roller at the shaft end of a braking shaft on the surface of a guide rail are controlled and changed through an electromagnetic clutch, so that cadence braking and continuous braking modes in a high-speed running state are achieved, and the design aims of not only improving the braking efficiency, but also giving consideration to reduction of the impact force on a goods shelf when the stacker is started up and stops are fulfilled. According to the braking method, in the process that an upper cross beam moves in the horizontal direction of the guide rail at the top end of the stacker, on-off of the electromagnetic clutch and the braking shaft is controlled through power-on and power-off, and switching between a rolling state and a sliding state of the roller on the surface of the guide rail is executed.

Description

technical field [0001] The invention relates to the improvement of a smooth braking method when the upper beam of a stacker is traveling, and belongs to the technical field of logistics storage. Background technique [0002] At present, various types of stackers are usually used in the operation and transportation site of the three-dimensional logistics storage. For the roadway stacker with a large vertical height of the shelf, when the upper beam is braked frequently and at high speed in the roadway, it is required to respond quickly and position accurately. However, due to the high equipment and heavy weight, the running inertia of the equipment is also large, which causes the upper end of the stacker to swing several times during braking before stopping, which seriously affects the efficiency of cargo transmission operations. [0003] as attached figure 1 The existing braking device shown has an overall structure consisting of a clamp support, a coil, a spring plate, a ...

AI Technical Summary

Problems solved by technology

[0004] The above electromagnetic clutch makes the two magnetic conductors adsorb on both sides of the track through electromagnetic action, but because the thickness of the two spring plates connecting the magnetic conductors is small and the mechanical strength is relatively limited, it is easier to tear when braking. The use reliability and practicability cannot meet the braking requirements of existing large-scale equipment

Moreover, after long-term use, the elasticity of the spring plate weakens, and the return elastic force is difficult to meet the design requirements. The gap between the fixture and the track becomes larger, resulting in a decrease in the braking force and an increase in the braking distance. The corresponding solution can only be to replace the spring plate , the production cost increases accordingly
