[0001] The invention belongs to the technical field of AGV cloth-dropping transport vehicles, and in particular relates to an AGV cloth-dropping transport device capable of preventing cloth from being damaged. Background Art

[0002] AGV is equipped with electromagnetic or optical automatic guidance devices. In order for AGV to move along a specified route, a special magnetic strip needs to be installed on the ground to guide the AGV to move. It is often used in factory production. Fabric production machines wind the produced fabric on a prepared roller, and then use AGV equipment to take the roller and fabric roll away for transportation. In the prior art, the AGV transport setting function is relatively simple. After the cloth roll is transferred from the equipment to itself, the cloth roll is not processed. Instead, the cloth roll is generally placed directly on the AGV transport trolley, and the cloth roll rolls on the AGV transport trolley. When the AGV is moving in an environment with an uneven ground, the cloth roll tilts during transportation, which can easily cause the cloth roll to fall and damage the cloth. In order to solve the above problems, the present application proposes an AGV cloth-dropping and transporting device that prevents cloth from being damaged. Summary of the invention

[0011] The AGV cloth-dropping and transporting device for preventing cloth damage of the present invention is preferably configured such that the moving block A and the two moving blocks B are both arranged in a trapezoidal table structure, and the cut surfaces at both ends of the abutment block are respectively adapted to the trapezoidal table surface.

[0012] It is preferred that the AGV cloth-dropping and transporting equipment for preventing cloth damage of the present invention has one end where the positioning rod passes through the supporting plate and is arranged as a rubber head structure.

[0013] The AGV cloth-dropping and transporting equipment for preventing cloth damage of the present invention is preferably configured such that the bearing positions of the four moving wheels are all equipped with connecting plates of a Z-shaped structure, and guide rods are all installed at the four corners inside the AGV chassis.

The two ends of the shock-absorbing spring are respectively connected to the connecting plate and the inside of the AGV chassis.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the AGV cloth drop trolley is taking the cloth from the cloth roller, it moves under the guidance of the magnetic strip.

After the teeth installed on the lower arc surface of the support plate are engaged with the gear, it is ensured that the support plate opening extends forward while the rotating block rotates, and the wound cloth is lifted, which is convenient for the AGV cloth drop trolley to take and transport the cloth. The design of the support plate can well avoid the problem of cloth damage.

[0015] 2. By setting a limit component, under the gravity of the cloth roll, the positioning rod in the middle of the support plate is squeezed, and the positioning rod is squeezed downward by the moving block A due to gravity. After the moving block A is squeezed and moved downward, the abutment blocks on both sides are moved to both sides around the center of the circle to squeeze the moving blocks B at both ends. The positioning rod on the moving block B is located in the hollow groove opened in the support plate under the contraction force of the spring B. After being squeezed, the positioning rod on the moving block B extends to the outside of the support plate, and is squeezed under the cloth roll's own gravity to limit the cloth roll, so that the cloth roll always remains in a stable state when it is transported or on an inclined ground. The stabilizing effect is good, and the cloth roll can be effectively prevented from falling during transportation.

[0016] 3. In order to reduce the vibration of the AGV chassis during the transportation of cloth rolls, connecting plates are installed on the four moving wheels. One end of the connecting plate slides on the surface of the guide rod. Under the tension of the shock-absorbing spring, the moving wheel extends from the inner part of the AGV chassis. The four moving wheels can effectively reduce the vibration on the ground under the action of the shock-absorbing spring, which greatly ensures the stability of the cloth rolls during transportation, avoids chrome marks on the surface of the cloth rolls during transportation, and improves the aesthetics of the product.

[0021] It should be noted that the driving wheels 5 on both sides rotate in opposite directions, so that the AGV chassis 1 can be quickly turned around on the spot, which makes it more flexible to use.

[0022] More specifically: like Figure 1-Figure 9 As shown: In combination with the above content, the material taking component 3 includes a mounting seat 31, a reduction motor 32, a rotating block 33, a servo motor 34, a gear 35, a support plate 36, a tooth 37, a fixed guide block 39 and a guide groove 310.

[0026] In this embodiment, a stabilizing block 311 is installed on the surface of the fixed guide block 39, and a stabilizing groove 312 adapted to the stabilizing block 311 is provided inside the supporting plate 36. The stabilizing block 311 and the fixed guide block 39 form a cross-shaped structure with good stability.

[0027] Going further: like Figure 1-Figure 9 As shown: In order to ensure that the fabric is not damaged when taking the fabric roll, in an optional embodiment: both ends of the support plate 36 are installed with triangular material taking blocks 38 through bolts.

[0028] In this embodiment, when taking materials, the material taking block 38 first contacts the cloth roll, and the cloth roll can roll down to the concave arc surface of the supporting plate 36 through the triangular structure of the material taking block 38, which is convenient for taking the cloth roll without causing damage to the cloth.

[0029] It should be noted that the corner of the material taking block 38 that contacts the cloth roll is an arc-shaped corner, and the material taking block 38 is made of rubber material, which can protect the cloth from damage.

[0030] More specifically: like Figure 1-Figure 9 As shown: In combination with the above content, the limit assembly 4 is arranged inside the supporting plate 36, and the limit assembly 4 includes a hollow groove 41, a fixed rod A42, a moving block A43, a spring A44, a moving block B45, a fixed rod B46, a spring B47, a jack 48, a positioning rod 49 and an abutment block 410. The interior of the supporting plate 36 is provided with a hollow groove 41 with an arc-shaped structure, and the interior of the supporting plate 36 is provided with a fixed rod A42 installed at the bottom surface of the hollow groove 41, and a moving block A43 is arranged inside the supporting plate 36.

Fixed rods B46 are fixedly installed on both sides of 42, and moving blocks B45 are arranged at the positions of the two fixed rods B46 inside the supporting plate 36. A socket 48 is opened inside the moving block B45, and one end of the fixed rod B46 is plugged into the moving block B45 through the socket 48. A spring B47 is installed at one end of the fixed rod B46 located in the moving block B45, and the other end of the spring B47 is connected to the inside of the moving block B45.
