Abstract
Description
Technical Field
[0001] This utility model relates to the field of palletizing machine technology, and specifically to a palletizing machine. Background Technology
[0002] A palletizer is a machine that automatically stacks containers or workpieces already filled with goods onto pallets or stacks in a specific arrangement. Multiple layers can be stacked, and the stacked goods are then pushed out for easy transport to a warehouse by forklift. Currently, palletizers are divided into robotic arm type and gantry type. Both operate from fixed workstations. When it is necessary to move the palletizer, its relatively heavy weight makes handling and relocation difficult, especially for large goods that require position and orientation adjustments during stacking. For example, in the gantry type palletizer used in food packaging workshops, the fixed position of the palletizer means that it is necessary to wait for a forklift to remove the stacked goods before continuing stacking. Currently, gantry palletizers do not have the necessary mobility. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a palletizing machine to solve the problems mentioned in the background art.

A rotating shaft is fixedly inserted through the second synchronous wheel on the upper surface of the support plate. The bottom end of the rotating shaft passes through the inside of the inverted U-shaped bracket and is connected to a first bevel gear that meshes with the second bevel gear.
[0008] As a preferred embodiment of the palletizer, the bottom end of the L-shaped steel plate is fixedly connected to the four corner side walls of the gantry palletizer, and the top end of the L-shaped steel plate extends to the side away from the gantry palletizer.
[0009] As a preferred embodiment of the palletizing machine, the telescopic shaft of the hydraulic cylinder is fixedly connected to the top surface of the support plate.

[0014] As a preferred embodiment of the palletizer, the two first synchronous pulleys are driven by a synchronous belt.
[0015] As a preferred embodiment of the palletizer, the two sprockets are connected by a chain.
[0016] The beneficial effects of this utility model are:

[0030] like Figure 3 As shown, the height control mechanism 2 specifically includes an L-shaped steel plate 21 and a hydraulic cylinder 22 fixed to the top end of the outer side of the L-shaped steel plate 21.
[0031] like Figure 4 As shown, the palletizer displacement mechanism 3 specifically includes a support plate 31, a servo motor 311 fixed to the top of the support plate 31, and a drive motor 310 fixed to the bottom outer side of the support plate 31. An inverted U-shaped bracket 34 is rotatably connected to the bottom surface of the support plate 31. A roller 36 is rotatably arranged at the bottom of the inner cavity of the inverted U-shaped bracket 34. A rotating shaft 37 is rotatably arranged at the top of the inner cavity of the inverted U-shaped bracket 34.

A second bevel gear 38 is fixedly connected to the middle section of the outer ring of the rotating shaft 37.
[0032] Specifically, in this embodiment, a first synchronous pulley 33 is fixedly connected to the top surface of the inverted U-shaped bracket 34 and the output shaft of the servo motor 311.

The bottom end of the rotating shaft 312 penetrates into the inverted U-shaped bracket 34 and is connected to a first bevel gear 32 that meshes with the second bevel gear 38.
[0033] More specifically, the bottom end of the L-shaped steel plate 21 is fixedly connected to the four corner side walls of the gantry palletizer 1, the top end of the L-shaped steel plate 21 extends to the side away from the gantry palletizer 1, the telescopic shaft of the hydraulic cylinder 22 is fixedly connected to the top surface of the support plate 31, after the telescopic shaft of the hydraulic cylinder 22 retracts, the bottom surface of the roller 36 is flush with the four corners of the gantry palletizer 1, after the telescopic shaft of the hydraulic cylinder 22 extends, the bottom surface of the roller 36 contacts the ground, and the bottom surface of the gantry palletizer 1 has a gap of 2-4cm with the ground.

[0035] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:
[0036] When the gantry palletizer 1 is stacking goods, if the stacking posture of containers containing food needs to be adjusted when stacking them onto a pallet, or if the pallet cannot be stacked further and the forklift cannot move the goods, the hydraulic cylinder 22 on the L-shaped steel plate 21 controls the palletizer displacement mechanism 3 to move downwards via the telescopic shaft until the roller 36 contacts the ground and the bottom of the gantry palletizer 1 has a gap of 2-4 cm with the ground. Then, the drive motor 310 rotates the second synchronous pulley 3 via the synchronous belt. 13, thereby causing the rotating shaft 312 and the first bevel gear 32 to rotate. Through the meshing relationship between the first bevel gear 32 and the second bevel gear 38, the rotating shaft 37 rotates. During the chain drive process of the sprocket 35, the roller 36 is driven to roll on the ground, thereby enabling the gantry palletizer 1 to perform linear movement. At the same time, after the first synchronous wheel 33 is driven to rotate by the servo motor 311, the inverted U-shaped bracket 34 is rotated and turns in place, thus enabling the gantry palletizer 1 to have the ability to turn during movement.
