A caster unit with one-way, two-way and vertical and horizontal switching and its agv device

Abstract

The invention provides a unidirectional, bidirectional and longitudinal-lateral switching trundle unit, which comprises a main body, a controller, a gear motor, a clutch and a trundle mechanism, wherein the controller is respectively connected with the gear motor and the clutch; the trundle mechanism comprises a trundle rack and a trundle rack shaft, wherein the trundle rack shaft is connected to the main body via a bearing; and the output shaft of the gear motor is connected with the trundle rack shaft via the clutch. The invention also provides an AGV (automatic guided vehicle) device, which comprises the unidirectional, bidirectional and longitudinal-lateral switching trundle unit. The unidirectional, bidirectional and longitudinal-lateral switching trundle unit and the AGV device thereof provided by the invention have the beneficial effects that the trundle rack carries out rotating movement at 90 degrees or any angle, trundles are switched between orientation and universal direction, and therefore the trundle unit can be generally used on any installation position of the AGV device. The unidirectional, bidirectional and longitudinal-lateral switching trundle unit and the AGV device thereof provided by the invention have the advantages of compact structure, small land occupation and flexibility in use and can be suitable for narrow space, free operation in each direction is realized, and the requirement on the use environment is lowered.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a one-way, two-way and vertically and horizontally switchable caster unit and an AGV device thereof. Background technique [0002] There are two types of existing casters, one is movable and the other is fixed. Swivel casters are often called universal wheels, and its structure can rotate freely 360 degrees; fixed casters have no rotating structure and cannot be rotated. Usually the two casters are used together. For example, the structure of the trolley is two fixed casters at the front, and two movable universal wheels at the back close to the push armrest. For other similar electric vehicles, the front two are universal wheels, and the back two are positioning wheels. That is to say, the end used to control the walking direction of the car must be a universal wheel, and the other end is a directional wheel, so as to control the walking direction of the car and ensu...

Problems solved by technology

[0003] In order to solve the above-mentioned existing technical problems, the present invention provides a one-way, two-way and vertically and horizontally switching caster unit and its AGV device, which can switch the caster from directional, universal, and vertically and horizontally, thereby solving problems caused by changing operation. The direction causes the problem that the AGV device cannot operate
