Description

Technical Field

[0001] This utility model belongs to the field of palletizing fixture technology, and relates to an adaptive buffer clamping anti-drop palletizing fixture. Background Technology

[0002] Palletizing is a crucial step in industrial automated logistics, widely used in packaging, warehousing, food, and building materials industries. As the core actuator in palletizing equipment, the fixture's structural design and clamping performance directly impact the efficiency and stability of the palletizing operation.

[0003] Existing palletizing fixtures mostly employ a rigid structure design, with clamping arms or blocks opening and closing via cylinders or electric drives to apply clamping force to the items being clamped. However, in practical applications, palletized materials sometimes exhibit size variations. When clamping items of different sizes, fixture adjustments are typically required, leading to operational complexity. Furthermore, existing fixtures usually only clamp the item from the top and bottom. If adjustments are incorrect or the item is too thin, it can easily detach from the fixture, causing damage and affecting the overall palletizing accuracy and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive buffer clamping anti-drop palletizing fixture to solve the problems mentioned in the background art, such as the inapplicability of existing palletizing fixtures to clamp items of various sizes and the easy drop of items.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An adaptive buffer clamping anti-drop palletizing fixture includes a base frame, on which a liftable lifting plate is provided, and a buffer limiting mechanism is provided below the lifting plate;

[0007] The buffer limiting mechanism includes multiple evenly distributed clamping blocks. The upper end of each clamping block is connected to the lifting plate via a screw. The screw passes through the lifting plate and is limited by a nut. A spring is sleeved on the screw, and the spring is located between the lifting plate and the clamping block.

[0008] When clamping an item, some clamping blocks contact the item and compress the spring to achieve buffer clamping, while the clamping blocks that do not contact the item play a role in limiting the item and preventing it from deviating.

[0009] Preferably, the base frame is equipped with a lifting cylinder, and the end of the extension rod of the lifting cylinder is connected to the lifting plate.

[0010] Preferably, an optical axis is installed above the upgrade plate, and a bushing is provided on the frame. The optical axis is slidably connected to the bushing, which is configured to guide the lifting and lowering of the lifting plate.

[0011] Preferably, it also includes a plug rod installed below the base frame and capable of moving horizontally. The plug rod can move to below the lifting plate to support the item, and then the lifting plate drives the buffer limiting mechanism to clamp the item.

[0012] Preferably, a guide rail is installed below the base frame, a slider is slidably connected below the guide rail, a movable frame is installed below the slider, the insertion rod is connected to the end face of the movable frame, and there are multiple insertion rods that are evenly distributed along the length of the movable frame.

[0013] Preferably, it also includes a drive assembly mounted on the rack and used to drive the moving frame to move.

[0014] Preferably, it also includes a baffle installed on the side of the frame and located between the insertion rod and the lifting plate.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0016] This utility model features a simple and reasonable design. By setting a spring structure between the lifting plate and the clamping block, the clamping block can achieve elastic displacement within a certain range during the clamping process. This allows the clamping block to contact the item and achieve a clamping effect, avoiding excessive clamping due to item size errors. This effectively improves the equipment's adaptability and safety to different materials. In addition, when some clamping blocks are not in contact with the item, they can still be used as limiting components for the item, preventing deviation and falling, enhancing stability during the clamping process, and reducing the risk of item displacement and falling during handling or stacking.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in the figure, an adaptive buffer clamping anti-drop palletizing fixture includes a base frame 1, on which a liftable lifting plate 5 is provided. In this example, the lifting plate 5 uses a lifting cylinder 2 as the driving source to achieve the lifting effect. That is, the base frame 1 is provided with a lifting cylinder 2, and the end of the telescopic rod of the lifting cylinder 2 is connected to the lifting plate 5. In order to achieve stable force, the end of the telescopic rod of the lifting cylinder 2 is connected to the center position of the lifting plate 5.

[0026] To ensure the stability of the lifting plate 5 during the lifting process, an optical axis 3 is installed above the lifting plate, and a bushing 4 is provided on the frame. The optical axis 3 is slidably connected to the bushing 4, serving as a guide for the lifting operation of the lifting plate 5. In this example, there are four optical axes 3, located near the four corners of the lifting plate 5. In other embodiments, the number of optical axes 3 can be two, three, or other numbers.

[0027] A buffer limiting mechanism 6 is provided below the lifting plate 5. Specifically, the buffer limiting mechanism 6 includes a plurality of evenly distributed clamping blocks 601. The upper end of each clamping block 601 is connected to the lifting plate 5 through a screw 604. The screw 604 passes through the lifting plate 5 and is limited by a nut 603. A spring 602 is sleeved on the screw 604. The spring 602 is located between the lifting plate 5 and the clamping block 601.

[0028] Multiple clamping blocks 601 are evenly distributed along the horizontal X and Y axes below the lifting plate 5. In their natural state, the lower planes of all clamping blocks 601 can be made coplanar by adjusting the position of the nut 603 on the screw 604. When clamping an item, some clamping blocks 601 contact the item and compress the spring 602 to achieve buffered clamping, while the clamping blocks 601 that do not contact the item play a role in limiting the item and preventing it from deviating. This design, on the one hand, uses the spring 602 as a buffer to avoid excessive clamping force due to excessive item thickness, which could damage the item, and also avoids the problem of ineffective clamping due to insufficient item thickness; on the other hand, since multiple clamping blocks 601 are evenly distributed, when clamping an item, some clamping blocks 601 will contact the item, and these clamping blocks 601 mainly play a clamping role, while the other clamping blocks 601 remain in their original positions (e.g., Figure 4 As shown, it can be placed on the side of an item to limit its movement and prevent it from falling.

[0029] Specifically, it also includes a plug rod 8 installed below the base frame 1 and capable of moving horizontally. The plug rod 8 can move to below the lifting plate 5 to support the item, and then the lifting plate 5 drives the buffer limiting mechanism 6 to clamp the item.

[0030] Specifically, a guide rail 11 is installed below the base frame 1, a slider 9 is slidably connected below the guide rail 11, a movable frame 10 is installed below the slider 9, and the insertion rod 8 is connected to the end face of the movable frame 10. There are multiple insertion rods 8, which are evenly distributed along the length of the movable frame 10.

[0031] Specifically, it also includes a drive assembly mounted on the frame and used to drive the moving frame 10 to move. In this example, the drive assembly mainly includes a drive motor 12, which is mounted on the base frame 1. A pulley is mounted on the shaft end of the drive motor 12. A pulley is also provided on the base frame 1 at a position away from the drive motor 12. A conveyor belt is mounted on the two pulleys. A connecting block 13 is fixed on the conveyor belt. The connecting block 13 is connected to the moving frame 10 below. By rotating the drive motor 12 forward or backward, the reciprocating movement of the moving frame 10 can be realized.

[0032] Specifically, it also includes a baffle 7 installed on the side of the frame and located between the insertion rod 8 and the lifting plate 5. In actual operation, the automated equipment (such as a robotic arm) is first connected to the base frame 1. When stacking, the baffle 7 is close to the side of the item. The drive motor 12 drives the moving frame 10 and the insertion rod 8 to extend forward and reach below the item. Then the lifting cylinder 2 is activated, which drives the lifting plate 5 and the buffer limit mechanism 6 to move down, thereby cooperating with the insertion rod 8 to clamp the item. After the automated equipment drives the base frame 1 and transfers the item to the designated position, the lifting plate 5 moves up and the insertion rod 8 retracts, thus completing the stacking operation.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
