Description

Technical Field

[0001] The utility model relates to the technical field of palletizers, in particular to a vertical palletizer. Background Art

[0002] A palletizer stacks cartons that have been loaded into containers in a certain arrangement on pallets or skids for automatic stacking. It can stack multiple layers and then push them out, facilitating forklift transportation to the warehouse for storage. It is controlled by PLC + touch screen to achieve intelligent operation management, which is simple and easy to master. It can greatly reduce labor force and labor intensity. A palletizer is a device that automatically stacks the material bags, cartons or other packaging materials conveyed by a conveyor into stacks according to the working mode required by the customer's process and transports the stacked materials.

[0003] At present, most palletizers use electric lifting cylinders to lift the arm rods. However, electric lifting cylinders cannot resist load levels, external forces or speed requirements. Some environments are not suitable for electric push rods, and there is a maximum speed that cannot be exceeded. Although it does not often occur, if the electric push rod has extreme changes during the working cycle or is used outside its guaranteed range, there may be overheating. The vibration load on the electric push rod will affect its lead screw or bearing, resulting in the possibility of affecting the entire lifting process. Moreover, there are many inconveniences in rotating and adjusting the palletizer, seriously affecting the working efficiency of the palletizer. Therefore, in view of the above problems, a vertical palletizer is proposed. Summary of the Utility Model

[0028] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 5 For a further detailed description of the present application,

[0029] The embodiments of the present application disclose a vertical palletizer. Refer to Figure 1 , Figure 2 and Figure 4 , a vertical palletizer includes a rotating assembly 1, a lifting assembly 2 is rotatably connected to the top of the rotating assembly 1, a clamping assembly 3 is fixedly connected to the bottom of the lifting assembly 2, and a conveying assembly 4 is arranged on the side of the rotating assembly 1;

[0030] The rotating assembly 1 includes a loading plate 101. A loading box 104 is fixedly connected to the loading plate 101. A first motor 110 is installed at the bottom of the loading box 104. A fixing plate 111 is fixedly connected to the side of the first motor 110. The output end of the first motor 110 is fixedly connected to a connecting rod 105. The top of the connecting rod 105 is fixedly connected to a first rotating wheel 106. The top of the fixing plate 111 is fixedly connected to a first bearing seat 112.

A second bearing seat 113 is fixedly connected to the top of the loading plate 101. By using the first motor 110 to drive the first rotating wheel 106 and the first transmission wheel 107 to mesh, the first rotating rod 108 is driven to rotate inside the second bearing seat 113, thereby driving the overall position of the lifting assembly 2 at the top of the first rotating rod 108 to change, improving the adaptability of the palletizer to grasp items at different positions;

[0031] The lifting assembly 2 includes a supporting plate 201. A third bearing seat 202 is fixedly connected to the top of the supporting plate 201. A loading frame 203 is fixedly connected to the top of the third bearing seat 202. A second motor 204 is installed at the top of the loading frame 203.

[0041] Working principle: By driving the first bevel gear 303 and the second bevel gears 304 on both sides thereof through the drive of the loading plate 301 to engage, the second lead screw 306 is rotated, and the second threaded block 307 moves inward under the action of the aluminum profile 305 and the second lead screw 306, so that the clamping plate 308 can clamp the article. Subsequently, the first motor 110 is used to drive the first rotating wheel 106 and the first transmission wheel 107 to engage, driving the first rotating rod 108 to rotate inside the second bearing block 113, and then driving the overall position of the lifting assembly 2 at the top of the first rotating rod 108 to change, so as to move the grabbed article to the top of the conveyor belt 407. Then, the second motor 204 is driven to drive the first lead screw 205 to rotate, and the first threaded block 206 is threaded on the first lead screw 205. Since the first threaded block 206, the slider 208 and the arm rod 209 are fixed as a whole, when the first threaded block 206 and the slider 208 move up and down, the position of the clamping assembly 3 at the bottom of the arm rod 209 can be driven to rise and fall. By reversing the loading plate 301, the two second threaded blocks 307 can be moved away from each other, and then the article can be stably placed on the conveyor belt 407. Finally, the fourth motor 402 is used to drive the transmission mechanism composed of the second rotating wheel 403, the belt 404 and the second transmission wheel 405 to drive the roller 406 to rotate, and then the conveyor belt 407 can drive the article to be conveyed.
