AI Technical Summary
Existing anti-collision mechanisms for automated warehouse shuttles are ineffective in reducing injuries during collisions, especially in cases involving pedestrians.
An anti-collision mechanism including a swing arm, a rubber buffer block, and a trigger switch was designed. The collision force is buffered by the rotation of the rubber buffer block and the swing arm, and the drive motor is braked by the trigger switch, so as to achieve flexible handling of the collision force.
It greatly reduces the degree of damage caused by collisions, has a simple structure and is easy to operate, and can effectively protect the safety of shuttle vehicles and surrounding personnel.

Abstract
Description
Technical Field
[0001] This invention relates to a shuttle vehicle for automated warehouses, and more particularly to an anti-collision mechanism used on such a shuttle vehicle. Background Technology
[0002] In automated storage and retrieval systems (AS / RS), shuttles travel on tracks within aisles to transfer goods. Anti-collision mechanisms are installed on the shuttle's frame to mitigate injury in the event of an accidental collision. Existing anti-collision mechanisms on the shuttle frame use polyurethane or rubber blocks, installed at the ends of the shuttle's traveling direction. These mechanisms are of two types: one is a polyurethane buffer block, located at the end of the shuttle frame directly above the track, used to buffer the impact force between the shuttle and the track end, preventing damage; the other is a trigger mechanism with a contact sensor that sends an electrical signal when a collision occurs, causing the shuttle to stop quickly. However, in actual operation, neither of these mechanisms is effective in reducing collision damage in the event of a shuttle colliding with a person. Developing a simpler mechanism that can significantly reduce collision damage has become a technical problem that needs to be solved on-site. Summary of the Invention
[0003] This invention provides an anti-collision mechanism for shuttle vehicles in automated warehouses, which solves the technical problem that existing anti-collision mechanisms cannot effectively reduce collision damage.
[0004] The present invention solves the above technical problems through the following technical solutions:
[0005] A collision avoidance mechanism for a shuttle car in an automated warehouse includes a track arranged in a left-right direction, on which a shuttle car is mounted; a first pin is provided at the left end of the shuttle car frame, a swing arm is movably hinged to the first pin, a second pin is provided at the outer end of the swing arm, a swing block is hinged to the second pin, a rubber buffer block is provided on the left end face of the swing block as a collision avoidance safety contact edge; a cantilever block is provided on the left side of the first pin, and a compression spring is connected between the cantilever block and the inner end of the swing arm.
[0006] A trigger switch is installed between the outer end of the swing arm and the swing block, and the trigger switch is electrically connected to the drive motor of the shuttle.
[0007] The angle between the swing arm and the left and right horizontal directions is an acute angle.
[0008] This invention has a simple structure and is easy to operate. It flexibly processes the collision force of the shuttle vehicle, greatly reducing the degree of damage caused by the collision. Attached Figure Description
[0009] Figure 1This is a schematic diagram of the structure of the present invention. Detailed Implementation
[0010] The present invention will now be described in detail with reference to the accompanying drawings:
[0011] A collision avoidance mechanism for a shuttle car in an automated warehouse includes a track 1 arranged in a left-right direction, on which a shuttle car 2 is mounted; a first pin 5 is provided at the left end 3 of the shuttle car 2's frame, a swing arm 6 is movably hinged to the first pin 5, a second pin 7 is provided at the outer end of the swing arm 6, a swing block 8 is hinged to the second pin 7, and a rubber buffer block 9 is provided on the left end face of the swing block 8; a cantilever block 12 is provided on the left side of the first pin 5, and a compression spring 13 is connected between the cantilever block 12 and the inner end of the swing arm 6, the compression spring 13 supporting and supporting the swing arm 6, causing it to tilt upward and extend to the left; when the shuttle car 2... During the journey from right to left, when the shuttle 2 encounters obstacle 11, the rubber buffer block 9 first contacts obstacle 11, causing the swing block 8 to rotate clockwise around the second pin 7. The trigger switch 10 is activated and sends an electrical signal, causing the drive motor of the shuttle 2 to enter the braking state. At the same time, under the impact force, the swing arm 6 rotates clockwise around the first pin 5. The driven swing arm 9 ensures that the swing block 8 is always in a horizontal position, thereby reducing the impact force. During the clockwise rotation of the swing arm 6, the compression spring 13 is stretched. After the obstacle 11 is removed, the swing arm 6 rotates counterclockwise and returns to its initial state.
[0012] A trigger switch 10 is provided between the outer end of the swing arm 6 and the swing block 8. The trigger switch 10 is electrically connected to the drive motor of the shuttle car 2. A collision protection mechanism, the same as the swing arm mechanism provided on the left end 3 of the frame, is also provided on the right end 4 of the frame of the shuttle car 2 to protect the shuttle car 2 when it travels to the right.
[0013] The angle between the swing arm 6 and the left and right horizontal directions is an acute angle; Figure 1 The text indicates the working state of the swing arm 6 before and after the collision.
