[0002] In the logistics industry, in order to reduce labor costs and improve the accuracy and speed of package processing, palletizers are used to automatically remove packages from conveyor belts and stack them to improve logistics handling efficiency. However, when existing palletizers carry packages by clamping, the clamping force applied to the packages is constant. When faced with lighter packages, it is easy to apply too much clamping force, resulting in damage to the packages. When faced with heavier packages, it is easy to apply too little clamping force, resulting in the packages falling during the handling process. It is difficult to adaptively adjust according to the gravity of the packages, and there are certain disadvantages when using them. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Logistics handling parcel palletizer is an automated device, usually used in logistics warehouses or sorting centers, to automatically take parcels from conveyor belts and palletize them according to specific rules. This machine can realize the automated processing of parcels, improve logistics handling efficiency, reduce labor costs, and improve the accuracy and speed of parcel processing.

[0025] Based on the technical defects of the existing technology that the clamping force cannot be adaptively adjusted when clamping the package, which affects the package handling, please refer to Figure 1-Figure 6The utility model provides a parcel stacking machine for logistics handling, which can apply different clamping forces according to the weight of the parcel itself to achieve adaptive adjustment of the clamping force, so as to avoid the problem that the parcel is damaged by the clamping or falls during the handling process. It has a transverse moving mechanism 1 and a longitudinal moving mechanism 2 with the same structure. The transverse moving mechanism 1 is provided with two groups and is fixedly connected to the positions at both ends of the longitudinal moving mechanism 2. A connecting frame 3 is fixedly provided at the bottom of the longitudinal moving mechanism 2, and a lifting mechanism 4 is installed on the connecting frame 3. An adjusting mechanism 5 for adaptively adjusting the clamping force according to the weight of the parcel is fixedly provided at the bottom of the lifting mechanism 4. A clamping mechanism 6 is fixedly provided on one side of the adjusting mechanism 5; the parcel is first clamped to a certain height by the clamping mechanism 6, and under the action of the weight of the parcel itself, the adjusting mechanism 5 automatically adjusts the current passing through the motor 3 62, so that its torque changes, so as to apply different sizes of clamping forces to the parcel. After the clamping is stable, the parcel is moved to the stacking position horizontally by the transverse moving mechanism 1 and the longitudinal moving mechanism 2, and finally the parcel is put down by the lifting mechanism 4.

[0026] To facilitate the adaptive adjustment of the clamping force of the clamping mechanism 6, please refer to Figure 5 The adjusting mechanism 5 includes a fixed plate 51 fixedly connected to the bottom of the lifting mechanism 4, and a slide groove is opened on the side wall of the fixed plate 51. An elastic component is slidably arranged in the slide groove, and a connecting block 55 is connected to the elastic component. The connecting block 55 is fixedly connected to the variable resistance block on the sliding rheostat 56, and the sliding rheostat 56 is installed on the side wall of the fixed plate 51. When the clamping mechanism 6 clamps the package to a certain height, the package itself has a certain gravity, so that the elastic component is forced to move downward, and then the variable resistance block on the sliding rheostat 56 is moved downward through the connecting block 55. As the descending distance increases, the resistance value of the sliding rheostat 56 gradually decreases. The smaller the resistance, the greater the current, thereby increasing the torque of the motor three 62, so as to achieve the purpose of adaptively adjusting the clamping force.

[0027] To facilitate the reset of the clamping mechanism 6, please refer to Figure 5 The elastic component includes a moving block 52 slidably set in the slide groove, the moving block 52 is sleeved on the guide rod 53, the guide rod 53 is fixed in the slide groove, and the outer wall of the guide rod 53 is sleeved with a spring 54 located below the moving block 52. When the package is put down, the moving block 52 moves up and resets under the elastic force of the spring 54, so that the resistance value of the sliding rheostat 56 is restored to its original state.

[0028] To facilitate moving the package to the palletizing position, please refer to Figure 2The longitudinal moving mechanism 2 includes a guide rail 21, at one end of which a motor 22 is installed. The output shaft of the motor 22 is fixedly connected to one end of a linear screw 23 which is rotatably connected to the guide rail 21. A threaded sleeve 24 is spirally connected to the linear screw 23. A moving platform 25 is fixedly provided on the threaded sleeve 24. Two sliders 26 are also fixedly provided on the moving platform 25. The sliders 26 are slidably set on the slide rail 27. The slide rail 27 is fixedly connected to the guide rail 21. The motor 22 works and drives the linear screw 23 to rotate. The linear screw 23 drives the moving platform 25 to move through the spiral transmission action with the threaded sleeve 24. Since the structures of the lateral moving mechanism 1 and the longitudinal moving mechanism 2 are the same, the clamping mechanism 6 can move horizontally and vertically along the horizontal position to achieve the purpose of moving the package.

[0029] To facilitate the handling of packages, please refer to Figure 4 The lifting mechanism 4 includes a motor 2 41 fixedly connected to one side of the connecting frame 3, a gear 1 42 is fixedly provided on the output shaft of the motor 2 41, the gear 1 42 is meshed with a gear rod 43, the gear rod 43 is sleeved in a guide sleeve 44, the guide sleeve 44 is fixedly connected to the bottom of the connecting frame 3, the bottom of the gear rod 43 is fixedly connected to the adjusting mechanism 5, the motor 2 41 works and drives the gear 1 42 to rotate, the gear 1 42 drives the clamping mechanism 6 to move up and down through the meshing action with the gear rod 43, so as to achieve the purpose of taking and placing the package.

[0030] To achieve the clamping and fixing of the package, please refer to Figure 6 The clamping mechanism 6 includes a connecting plate 61 fixedly connected to one side of the elastic component, and a motor three 62 is installed on the side wall of the connecting plate 61. A gear two 63 is fixedly provided on the output shaft of the motor three 62. The gear two 63 meshes with the gear three 64. The gear three 64 is rotatably connected to the mounting plate 65 through a rotating shaft. The mounting plate 65 is fixedly connected to the connecting plate 61. The surface of the gear three 64 is hinged to the two guide blocks 67 through two connecting rods 66. The two guide blocks 67 are respectively slidably arranged in two guide holes opened on the mounting plate 65. The bottoms of the two guide blocks 67 are fixed with clamping plates 68. The motor three 62 works and drives the gear two 63 to rotate. The gear two 63 drives it to rotate by meshing with the gear three 64. The gear three 64 drives the guide block 67 to move through the connecting rod 66. The guide block 67 reaches the two clamping plates 68 and approaches each other, thereby clamping the package.

[0031] In order to achieve adaptive change of clamping force, the sliding rheostat 56 is connected to the motor three 62 through a wire. When the resistance value of the sliding rheostat 56 changes, the current passing through the motor three 62 can be adjusted. When the motor current is less than the rated current, the current is proportional to the torque, so the torque of the motor three 62 will increase, thereby adjusting the clamping force of the clamping mechanism 6.

[0032] Through the above embodiment, it can be known that: the clamping mechanism 6 is moved to the position of the package, and then the motor 3 62 is used to work and drive the gear 2 63 to rotate, and the gear 2 63 drives it to rotate by meshing with the gear 3 64, and the gear 3 64 drives the guide block 67 to move through the connecting rod 66, and the guide block 67 reaches the two clamping plates 68 close to each other, so that the package is clamped, and after clamping, the motor 2 41 is used to work and drive the gear 1 42 to rotate, and the gear 1 42 drives the clamping mechanism 6 to move upward by meshing with the gear rod 43, so that the package is clamped. The package is lifted to a certain height. At this time, under the action of the weight of the package, the elastic component is forced to move downward, and then the variable resistance block on the sliding rheostat 56 is moved downward through the connecting block 55. As the descending distance increases, the resistance value of the sliding rheostat 56 gradually decreases. The smaller the resistance, the greater the current, thereby increasing the torque of the motor three 62 and the clamping force applied to the package. When the package is adaptively clamped, the lateral moving mechanism 1 and the longitudinal moving mechanism 2 are used to move the package horizontally to the stacking position, and finally the lifting mechanism 4 is used to put the package down.
