Description

Technical Field

[0001] This utility model relates to a suction cup type case packing machine opening limit device, belonging to the field of case packing machine packaging technology. Background Technology

[0002] A suction cup carton packer is an automated packaging device that relies on the principle of vacuum negative pressure adsorption to complete tasks such as carton picking, opening, bottom folding, and positioning. In operation, the suction cup carton packer first uses a set of suction arms and suction cups to pull the stacked cartons from the carton hopper. Then, another set of suction arms and suction cups holds the other side of the carton. The suction arms then adjust the two sets of suction cups to a relatively perpendicular state, thus opening the carton. The opened carton is then sent into the packing position, and the two sets of suction arms and suction cups return to their initial positions to begin the next carton picking and opening process. During the retraction of the two sets of suction arms and suction cups, although the vacuum of the suction cups has been released and they are no longer gripping the cartons, one set of suction cups retracts while still close to the side wall of the carton. Due to the friction between the suction cups and the carton, the suction cups may pull the cartons already placed in the packing position backward during retraction. This could cause the cartons to shift position, ultimately preventing the robotic arm from accurately placing the medicine into the carton, resulting in packing failure. This necessitates manual intervention, impacting production efficiency and increasing labor costs. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a suction cup type carton opening limit device that can limit the carton fed into the packing position.

[0004] The suction cup type box packing machine opening and limiting device of this utility model includes a support plate, a swing plate rotatably connected to the support plate, one end of the swing plate extending out of the support plate, and a limiting block fixedly connected to the other end of the swing plate. A limiting plate that fits against the limiting block is fixedly connected to the support plate. An elastic component is connected between the support plate and the swing plate. The elastic component is used to keep the limiting block in the position of fitting against the limiting plate in its natural state.

[0005] Working principle and process: During operation, the cardboard box, after being opened, is fed into the packing position from left to right. As the box moves to the right, its side wall first contacts the side of the outer swing plate. As the box continues to move to the right, it pushes the outer end of the swing plate to overcome the elastic force of the elastic component and swing inward, allowing the box to pass smoothly through the swing plate. When the box reaches the packing position, its side wall just passes the swing plate. At this point, the pushing force of the box on the swing plate disappears. Under the elastic reset action of the elastic component, the outer end of the swing plate swings outward again and blocks the box. Thus, when the suction cup retracts, the swing plate blocks the box, effectively preventing the box from shifting and ensuring the accuracy of the box's packing position. This ensures the stable operation of the equipment, reduces manual intervention, improves production efficiency, and lowers labor costs.

[0006] Furthermore, the elastic component includes a connecting rod fixedly connected to the limiting block end of the swing plate and a connecting pin fixedly connected to the bearing plate. An elastic element is connected between the connecting rod and the connecting pin. The elastic element is connected between the connecting rod and the connecting pin in a stretched state. When the carton pushes the swing plate, the outer span end of the swing plate will overcome the tension of the elastic element and swing inward. When the carton passes over the swing plate and separates from it, the outer span end of the swing plate can swing outward again under the tension of the elastic element, and be positioned by the cooperation of the limiting block and the limiting plate.

[0007] Furthermore, the support plate has a first through hole. The support plate can be fixedly connected to the frame of the suction cup carton packer through the first through hole and bolts. Under the action of the first through hole, the installation position of the support plate can be adjusted, thereby adapting to the relevant operations of cartons of different sizes.

[0008] Furthermore, the support plate is threaded with fastening screws, and the limiting plate is L-shaped. One wall of the limiting plate corresponds to and fits against the limiting block, while the other wall of the limiting plate has a second through hole. The limiting plate is fixedly connected to the support plate by the fastening screws through the second through hole. By loosening the fastening screws, the position of the limiting plate can be adjusted under the action of the second through hole, thereby adjusting the outer span position of the swing plate and improving the applicability of the device.

[0009] Furthermore, the swing plate is rotatably connected to the bearing plate via a hinge shaft, resulting in a simple structure and stable operation.

[0010] Furthermore, a baffle is fixedly connected to the outer span of the swing plate, which can effectively increase the contact area with the carton, thereby effectively preventing damage to the carton.

[0011] Furthermore, the outer edge of the baffle is rounded to prevent scratches on the carton when it moves relative to the baffle, thus providing protection.

[0012] The advantages of this utility model compared with the prior art are: The suction cup type carton opening limit device of this utility model, on the one hand, does not affect the smooth movement of the carton to the packing position, and on the other hand, can block the carton when it reaches the packing position, effectively preventing the carton from shifting as the suction cup retracts, thereby ensuring the accuracy of the carton packing position and further ensuring the stable operation of the equipment, reducing manual intervention, improving production efficiency and reducing labor costs.

[0015] The embodiments of this utility model will be further described below with reference to the accompanying drawings: Example 1: like Figures 1 to 4 As shown, the suction cup type box packing machine opening and limiting device of this utility model includes a support plate 1, a swing plate 3 rotatably connected to the support plate 1, one end of the swing plate 3 extending outward from the support plate 1, and a limiting block 6 fixedly connected to the other end of the swing plate 3. A limiting plate 7 that fits against the limiting block 6 is fixedly connected to the support plate 1. An elastic component is connected between the support plate 1 and the swing plate 3. The elastic component is used to keep the limiting block 6 in a position that fits against the limiting plate 7 in a natural state.

[0016] Furthermore, the elastic component includes a connecting rod 10 fixedly connected to the end of the limiting block 6 of the swing plate 3 and a connecting pin 12 fixedly connected to the bearing plate 1. An elastic component 11 is connected between the connecting rod 10 and the connecting pin 12. The elastic component 11 can be a tension spring or an elastic rope. The elastic component 11 is connected between the connecting rod 10 and the connecting pin 12 in a stretched state. When the carton pushes the swing plate 3, the outer span of the swing plate 3 will overcome the tension of the elastic component 11 and swing inward. When the carton passes over the swing plate 3 and separates from the swing plate 3, the outer span of the swing plate 3 can swing outward again under the tension of the elastic component 11, and be positioned by the cooperation of the limiting block 6 and the limiting plate 7.

[0017] Furthermore, the support plate 1 has a first through hole 2. The support plate 1 can be fixedly connected to the frame of the suction cup carton packer through the first through hole 2 and bolts. Under the action of the first through hole 2, the installation position of the support plate 1 can be adjusted, thereby adapting to the relevant operations of cartons of different specifications.

[0018] Furthermore, a fastening screw 9 is threaded onto the support plate 1. The limiting plate 7 is L-shaped, with one wall corresponding to and fitting against the limiting block 6. A second strip-shaped through hole 8 extends through the other wall of the limiting plate 7. The limiting plate 7 is fixedly connected to the support plate 1 via the second strip-shaped through hole 8 and the fastening screw 9. By loosening the fastening screw 9, the position of the limiting plate 7 can be adjusted under the action of the second strip-shaped through hole 8, thereby adjusting the outer span position of the swing plate 3 and improving the applicability of the device.

[0019] Furthermore, the swing plate 3 is rotatably connected to the bearing plate 1 via the hinge shaft 5, resulting in a simple structure and stable operation.

[0020] Furthermore, a baffle 4 is fixedly connected to the outer span of the swing plate 3. The baffle 4 can effectively increase the contact area with the carton, thereby effectively preventing damage to the carton.

[0021] Furthermore, the outer edge of the baffle 4 is provided with a rounded corner 13, which can prevent the carton from being scratched when it moves relative to the baffle 4, thus providing protection.

[0022] In use, after the carton is opened, it is fed into the packing position from left to right. As the carton moves to the right, the side wall of the carton first contacts the side of the outer swing plate 3. As the carton continues to move to the right, the carton pushes the outer end of the swing plate 3 to overcome the tension of the elastic component 11 and swing inward, so that the carton can pass smoothly through the swing plate 3. When the carton moves to the packing position, the side wall of the carton just passes the swing plate 3. At this time, the pushing force of the carton on the swing plate 3 disappears. Under the tension of the elastic component 11, the outer end of the swing plate 3 swings outward again and abuts against the carton. Thus, when the suction cup retracts, the swing plate 3 blocks the carton, effectively preventing the carton from shifting. This ensures the accuracy of the carton packing position, thereby ensuring the stable operation of the equipment, reducing manual intervention, improving production efficiency, and reducing labor costs.

[0023] Example 2: like Figure 5 As shown, based on Embodiment 1, the elastic component includes a spring seat 14 fixedly connected to the support plate 1, and a compression spring 15 fixedly connected to the spring seat 14. The end of the compression spring 15 abuts against the side wall of the outer span end of the swing plate 3. The compression spring 15 is installed on the spring seat 14 in a compressed state. When the carton pushes the swing plate 3, the outer span end of the swing plate 3 will overcome the elastic force of the compression spring 15 and swing inward. When the carton passes over the swing plate 3 and separates from the swing plate 3, under the elastic reset action of the compression spring 15, the outer span end of the swing plate 3 can swing outward again and be positioned by the cooperation of the limiting block 6 and the limiting plate 7.
