Box pulling device, material transporting robot and material transporting method

Abstract

The invention provides a box pulling device, a material transporting robot and a material transporting method. The box pulling device comprises a main body, a driving assembly, a swing hook piece anda first stroke switch, the driving assembly is placed in the main body, the swing hook piece and the first stroke switch are arranged outside the main body, the swing hook piece comprises a connectingpart, a cantilever part and a swing hook part, the connecting part and the swing hook part are connected with the two ends of the cantilever part respectively, the connecting part is fixedly connected with a rotating output shaft of the driving assembly, the cantilever part extends in the axial direction of the rotating output shaft, and the swing hook part extends towards the outer periphery inthe direction of being perpendicular to the cantilever part from the extending end of the cantilever part. The material transporting robot comprises the box pulling device. The material transporting method comprises the steps that a sliding rail assembly is driven to make the box pulling device move horizontally and outwards in the horizontal direction, whether the contact signal from the first stroke switch is obtained is judged, if yes, the sliding rail assembly is stopped driving, and the driving assembly is started to make the swing hook part rotate along the rotating output shaft. The work of a lifting device and the sliding rail assembly is simplified, the structure of the box pulling device is simple, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of material transportation equipment, in particular to a box pulling device, a material transportation robot and a material transportation method. Background technique [0002] There is an existing material transport robot for dragging and transporting material boxes from shelves. This material transport robot includes a body, a drive wheel assembly, a lifting device, a slide rail assembly, and a box pulling device. The drive wheel assembly is installed on the bottom of the body. At the bottom, the lifting device is installed on the upper part of the body. The lifting device includes a lifting platform, the slide rail assembly is installed on the lifting platform, and the box pulling device is installed on the sliding rail assembly; It can translate horizontally relative to the lifting platform. [0003] The extended end of the box-drawing device has a pull hook that protrudes forward and bends downward, an...

AI Technical Summary

Problems solved by technology

[0004] The existing problem of this kind of material transportation robot is that in the process of adjusting the position of the box-drawing device until the draw hook enters the jack of the material box, the lifting device and the slide rail assembly work many times, and every time the lifting device and the slide rail assembly Each job involves position sensing and calculation, and the work efficiency is low
