[0002] With the development of automation technology in textile machinery, it is often necessary to layer stacked fabric products for picking to ensure that the fabric products are picked up in a single layer and avoid picking up multiple layers of fabric at once. Some existing technologies use adhesive picking devices, which usually use tape to stick the products together. However, during the process of picking and moving products, the products often fall off because the tape is not firmly attached. Utility Model Content

[0003] Therefore, to solve the above problems, this utility model provides a material handling gripper.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A material handling gripper includes a material handling mechanism and a connecting seat. The material handling mechanism is mounted on the connecting seat and includes a mounting frame, a drive wheel, a driven wheel, a material handling head, a conveyor belt, and a braking component. The drive wheel, driven wheel, and material handling head are all arranged on the mounting frame. The conveyor belt passes sequentially around the driven wheel, the material handling head, and the drive wheel. The drive wheel is equipped with a drive source for pulling the conveyor belt. The braking component is connected to the driven wheel and is used to brake or release the brake on the driven wheel.

[0006] Optionally, the material handling mechanism further includes a driving component and a release plate; the driving component is arranged on a connecting seat; the mounting bracket is connected to the output end of the driving component, the release plate is connected to the fixed end of the driving component, and the release plate has a working hole for the material handling head to pass through; the driving component can drive the mounting bracket to move so that the material handling head can pass through or exit the working hole.

[0007] Optionally, the driving component includes a cylinder, which is arranged on a connecting seat. The release plate is connected to the cylinder body, and the piston rod end of the cylinder is connected to the mounting bracket. The cylinder can drive the mounting bracket to move so that the material take-up head can enter or exit the working hole.

[0008] Optionally, the mounting bracket includes a connecting rod and a horizontal plate. The connecting rod has an L-shaped structure. One end of the connecting rod is axially and perpendicularly connected to the piston rod of the cylinder, and the other end extends toward the cylinder body.

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figure 1-4 This embodiment provides a material-grabbing gripper, including a material-grabbing mechanism 1 and a connecting seat 2. The material-grabbing mechanism 1 is mounted on the connecting seat 2 and includes a mounting frame 3, a driving wheel 4, a driven wheel 5, a material-grabbing head 6, a tape 7, and a braking component 8. The driving wheel 4, driven wheel 5, and material-grabbing head 6 are all mounted on the mounting frame 3. The tape 7 sequentially passes around the driven wheel 5, the material-grabbing head 6, and the driving wheel 4. Specifically, the tape 7 is wound onto the driven wheel 5. When the tape 7 is pulled out, it passes through the material-grabbing head 6 and is then wound onto the driving wheel 4. The driving wheel 4 is equipped with a drive source, which is a drive motor 41. The drive motor 41 drives the driving wheel 4 to rotate. The tape 7 is wrapped around the driving wheel 4 and the driven wheel 5, thereby driving the driven wheel 5 to rotate, thus moving the new tape 7 to the position of the material-grabbing head 6, enabling effective adhesion and material grabbing of the product. The driven wheel 5 is equipped with a braking component 8 for braking or releasing the brake on the driven wheel 5. When the drive wheel 4 drives the driven wheel 5 to rotate, the tape 7 is pulled out to a new length. At this time, the driven wheel 5 is braked by the brake 8. The drive wheel 4 continues to rotate through the drive motor 41, so that the tape 7 can be pulled taut. The back of the tape 7 on the pick-up head 6 can be tightly attached to the pick-up head 6. This makes it more stable when pasting product fabric, and the product is less likely to fall off during movement, thus improving work efficiency.

[0024] To enable the fabric product to automatically detach after being picked up, the picking mechanism 1 also includes a drive component and a release plate 10. The drive component is arranged on the connecting seat 2, the mounting bracket 3 is connected to the output end of the drive component, and the release plate 10 is connected to the fixed end of the drive component. The release plate 10 has a working hole 101 through which the picking head 6 can pass. The driving end of the drive component can drive the mounting bracket 3 to move, thereby driving the picking head 6 to pass through or exit the release plate 10; that is, it can pick up the fabric product and, when the picking head 6 exits the release plate 10, the release plate 10 can be used to separate the fabric from the picking head 6.

[0025] Specifically, the driving component includes a cylinder 9, which is arranged on the connecting seat 2. The release plate 10 is connected to the cylinder body of the cylinder 9, and the piston rod end of the cylinder 9 is connected to the mounting bracket 3. The cylinder 9 can drive the mounting bracket 3 to move so that the material taking head 6 can enter or exit the working hole 101.

[0026] Mounting bracket 3 includes a connecting rod 31 and a horizontal plate 32. The connecting rod 31 has an L-shaped structure, with one end axially perpendicularly connected to the piston rod of cylinder 9, and the other end extending towards the cylinder body of cylinder 9. The horizontal plate 32 is perpendicularly connected to the end of the connecting rod 31 near the cylinder body. The driving wheel 4 and the driven wheel 5 are respectively arranged on both sides of the length of the horizontal plate 32. This arrangement makes the material handling mechanism 1 compact, occupies less space, and is easy to assemble.

[0027] The feeding head 6 has a working surface 61, and the feeding head 6 is provided with guide grooves 62 on both sides of the working surface 61. The tape 7 passes through the guide grooves 62, the working surface 61 and the guide grooves 62 in sequence. This ensures that the tape 7 will not deviate during the pulling process, so that the non-stick side of the tape 7 can be stably attached to the working surface 61.

[0028] Reference Figure 4 The working surface 61 has an outward-convex, arc-shaped structure. Since the product being gripped is fabric, which has a certain degree of softness, designing the working surface 61 as an outward-convex arc-shaped structure ensures that the tape 7 on the picking head 6 can fully contact the fabric when it is being gripped, increasing the effective bonding area of ​​the tape 7. The picking head 6 also has a connecting part 63, which is fixedly connected to the mounting frame 3 and extends in a direction away from the connecting seat 2. The working surface 61 is located at the end of the picking head 6 furthest from the connecting part 63. Thus, the tape 7 is sequentially wound around the driven wheel 5, the picking head 6, and the driving wheel 4, and the pulled-out tape 7 is U-shaped, maintaining a tight fit between the tape 7 on the working surface 61 and the working surface 61.

[0029] Furthermore, the braking component 8 employs an electromagnetic brake, which can brake the driven wheel 5. The electromagnetic brake is connected to the shaft of the driven wheel 5, occupying little space and having low cost.

[0030] At least two material handling mechanisms 1 are arranged at intervals. In this embodiment, three material handling mechanisms 1 are arranged at intervals in a triangular pattern to adapt to the shape of the product and ensure the stability of the product handling.

[0031] This embodiment also discloses a material handling device, including a moving mechanism and the aforementioned material handling gripper. The moving mechanism is connected to the connecting seat 2 of the material handling gripper, and the moving mechanism can drive the material handling gripper to translate and rotate.

[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
