Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] An automatic weighing palletizer includes: a feeding assembly, a weighing machine 20, a palletizing table 30, and a conveyor line.

[0022] The material feeding assembly includes a Z-axis moving module 10, an X-axis moving module 11 disposed on the Z-axis moving module 10, and a gripper 13 disposed on the X-axis moving module 11. The palletizing station 30 is disposed below the X-axis moving module 11.

[0023] The Z-axis moving module 10 can drive the X-axis moving module 11 to reciprocate in the Z-axis direction. The X-axis moving module 11 can drive the gripper 13 to reciprocate in the X-axis direction. The X-axis moving module 11 and the Z-axis moving module 10 work together to move the gripper 13 to the position of the material to be gripped. When the gripper 13 reaches the material position, the gripper 13 closes and grips the material. After gripping the material, the gripper 13 starts to move under the drive of the X-axis moving module 11 and the Z-axis moving module 10 to transport the material to the palletizing table 30 for palletizing operation.

[0024] The weighing machine 20 is located below the feeding assembly, and the palletizing platform 30 is mounted on the weighing machine 20 along the Y-axis. Multiple sets of conveying rollers 301 are rotatably mounted inside the palletizing platform 30. Adjacent sets of conveying rollers 301 are linked by a transmission belt. One set of conveying rollers 301 is linked to the power end of the motor by a transmission belt. Fixed plates 31 are fixedly connected to both sides of the palletizing platform 30. Elastic elements are provided on the fixed plates 31. A guide element is provided at the end of the elastic element located above the palletizing platform 30. The conveyor line 40 is located at the feeding end of the palletizing platform. The feeding assembly is controlled to stack the material on the palletizing platform 30. The weighing machine 20 weighs the material on the palletizing platform 30. When the material reaches a preset value, the palletizing platform conveys the material to the conveyor line 40.

[0025] Specifically, the material is moved onto the palletizing platform 30 by the feeding assembly. At this time, the elastic elements and guide elements on the fixed plates 31 on both sides of the palletizing platform 30 play their role. The elastic elements can adjust the distance between the two sets of guide elements according to the material, and adjust the area of ​​the placement area on the palletizing platform. The guide elements can guide the material to fall onto the palletizing platform 30, assisting the material to be stacked in an orderly manner, and ensuring the stability and neatness of the palletizing process. As the material gradually accumulates on the palletizing platform 30, the weighing machine 20 below continuously monitors the weight of the material on the palletizing platform 30. When the weighing machine 20 detects that the weight of the material on the palletizing platform 30 reaches the preset value, the motor runs, and drives the connected conveyor roller 301 to rotate through the transmission belt, thereby driving the other conveyor rollers 301 to rotate synchronously, so that the material that has been stacked on the palletizing platform 30 and has reached the preset weight is conveyed along the Y-axis to the conveyor line 40. This completes a complete automatic weighing and palletizing process. Afterwards, the feeding assembly continues to feed material onto the palletizing platform 30 and repeats the above steps to realize continuous automatic material palletizing and conveying.

[0026] In one embodiment, the elastic element includes multiple sets of movable rods 34 movably inserted into the fixed plate 31. One end of each movable rod 34 located above the palletizing platform 30 is fixedly connected to the guide member. A spring 35 is wound around the surface of the movable rod 34 between the guide member and the fixed plate 31.

[0027] Specifically, the guide members, supported by the elasticity of the movable rod 34 and the spring 35, guide the position of the material during its descent. When a wider material falls, its edge contacts and pushes the two sets of guide members to move away from each other. During this process, the movable rod 34 slides on the fixed plate 31, and the spring 35 undergoes elastic deformation under compression, thereby dynamically adjusting the placement area on the palletizing platform to accommodate the size of the material. When a narrower material falls, the spring 35, with its own elastic restoring force, pushes the guide members to move closer to each other, and the movable rod 34 moves accordingly, reducing the placement area on the palletizing platform. This ensures that the palletizing platform can always provide suitable placement space for the material, so that when the palletizing platform 30 is conveying materials, the elastic members and guide members can prevent the material from shifting or tipping over, improving the quality and stability of the palletizing.

[0028] In one embodiment, the guide includes a second guide plate 33 fixedly connected to the movable rod 34. The second guide plate 33 has multiple sets of rotating rollers 32 arranged inside it along the Y-axis. The top of the second guide plate 33 has an inclined guide plate 32. The first guide plate 32 has multiple sets of rotating rollers 321 arranged inside it along the Z-axis. The distance between the two sets of first guide plates 32 gradually decreases from top to bottom.

[0029] Specifically, during the descent of the material, it first comes into contact with guide plate 32. The distance between the two sets of guide plates 32 gradually decreases from top to bottom, forming a funnel-like structure, which helps to gather and position the falling material. When the material falls from above, the wider upper distance makes it easier to receive the material. As the material falls, the gradually decreasing distance guides the material to concentrate towards the center position, allowing the material to land more accurately in the appropriate position on the palletizing platform, improving the neatness of the palletizing. The rotating roller 321 allows the material to slide smoothly along the inclined surface of the guide plate 32 to reduce friction. Furthermore, the guide plate 32 compresses the elastic element according to the width of the material. After the material lands on guide plate 33, it can effectively prevent tipping during the conveyor line process. The rotating roller 331 can reduce the friction during material conveying.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
