Description

Technical Field

[0001] This utility model relates to the field of palletizing equipment technology, specifically a relay palletizing machine. Background Technology

[0002] In industrial production, palletizing refers to stacking products with basically the same shape according to certain requirements. In industrial production lines, packaged items generally need to be moved from the workshop assembly line to the warehouse for palletizing in order to facilitate storage and transportation. Palletizing is mostly done manually. When there is a large amount of work to be done, such as a large number of palletized items or heavy boxes, manual palletizing becomes very difficult.

[0003] Currently, the standard operating method of single-column palletizers is basically to control the longitudinal movement through the main lifting device and the lateral movement through the transverse device. This method requires the entire layer of palletizer to move in four directions. This equipment changes this workflow by using a special operating method, retaining only the longitudinal movement of the entire layer of palletizer. This effectively improves the stability during palletizing and transfer. Moreover, no palletizer on the market currently has this type of relay palletizer that achieves stable palletizing and transfer. Utility Model Content

[0004] The purpose of this invention is to provide a relay palletizing machine that improves stability during palletizing transfer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a relay palletizing machine, comprising a column assembly, an upper lifting trolley assembly, a lower lifting trolley assembly, a mesh belt conveyor assembly, and a full-layer gripper assembly. The upper lifting trolley assembly is slidably installed on the front of the column assembly, and the lower lifting trolley assembly is slidably installed on the front of the column assembly. The upper lifting trolley assembly is located above the lower lifting trolley assembly. The mesh belt conveyor assembly is fixedly installed on one side of the lower lifting trolley assembly, and the full-layer gripper assembly is fixedly installed on one side of the upper lifting trolley assembly.

[0006] For ease of transportation, in the preferred embodiment of the relay palletizing machine of this utility model, the column assembly includes a base front support fixedly installed on one side of the welding base, a lower column assembly fixedly installed on the top of the welding base, an upper column assembly fixedly installed on the top of the lower column assembly, a main lifting device fixedly installed on the top of the upper column assembly, anti-fall hanging plates fixedly installed on one side of both the lower column assembly and the upper column assembly, and side guide rails fixedly installed on the left and right sides of both the lower column assembly and the upper column assembly.

[0007] In order to achieve the lifting action, as a preferred embodiment of the relay palletizing machine of this utility model, the upper lifting trolley assembly includes a support plate frame assembly fixedly installed on one side of the crossbeam frame assembly, and an upper lifting trolley frame assembly fixedly installed on the other side of the crossbeam frame assembly. The upper lifting trolley frame assembly is movably installed with the side guide rail.

[0008] To further realize the lifting action, as a preferred embodiment of the relay palletizing machine of this utility model, the lower lifting trolley assembly includes a lifting fork crank arm assembly fixedly installed on one side of the lower lifting trolley assembly, and the lower lifting trolley assembly is movably installed with the side guide rail.

[0009] To facilitate palletizing, the preferred relay palletizing machine of this utility model includes a second roller rotatably mounted below one side of the mesh belt conveyor assembly, a first roller rotatably mounted above the other side of the mesh belt conveyor assembly, and multiple flat parallel pads arranged above the mesh belt conveyor assembly.

[0010] To facilitate further palletizing, the preferred embodiment of the relay palletizing machine of this utility model includes a mounting base fixedly installed on the top of the entire layer gripper assembly, a cylinder movably installed on the inner side of the entire layer gripper assembly, a spherical bearing fixedly installed on one side of the entire layer gripper assembly, and a box-in guide frame rotatably installed on the outer side of the spherical bearing. The output end of the cylinder is movably connected to one side of the box-in guide frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the original palletizing method is completely changed by the upper and lower lifting trolley components. The gripper, which originally required up-down and left-right movement, is transformed into a palletizing method that can be completed by the lifting and lowering of the upper and lower lifting trolley components. This eliminates the left-right movement, allowing the device to complete the series of actions more smoothly during the palletizing process. It is applicable to various types of palletizing equipment. Moreover, compared with the traditional single-column palletizer, the lateral movement of the entire layer of gripper components is eliminated, which allows the entire layer of gripper components to achieve a more stable palletizing form during the transfer process.

The upper lifting trolley assembly is located above the lower lifting trolley assembly. The mesh belt conveyor assembly is fixedly installed on one side of the lower lifting trolley assembly, and the full-layer gripper assembly is fixedly installed on one side of the upper lifting trolley assembly.

[0016] By using the upper and lower lifting trolley components, the lateral movement of the entire layer gripper component is eliminated, enabling the entire layer gripper component to achieve a more stable stacking method during the transfer process than usual.

[0017] As a technical optimization of this utility model, the column assembly includes a base front support 3 fixedly installed on one side of the welding base 1, a lower column assembly 4 fixedly installed on the top of the welding base 1, an upper column assembly 5 fixedly installed on the top of the lower column assembly 4, a main lifting device 6 fixedly installed on the top of the upper column assembly 5, a fall protection plate 7 fixedly installed on one side of both the lower column assembly 4 and the upper column assembly 5, and side guide rails 2 fixedly installed on the left and right sides of both the lower column assembly 4 and the upper column assembly 5.

[0018] The column is designed as a split unit by using the lower column assembly 4 and the upper column assembly 5, which makes the main body more convenient to transport. The interior of the lower column assembly 4 and the upper column assembly 5 is divided into two counterweight boxes with upper and lower sliding channels, which are used for lifting the upper lifting trolley assembly and the lower lifting trolley assembly, respectively.

[0019] As a technical optimization of this utility model, the lifting trolley assembly includes a support plate frame assembly 801 fixedly installed on one side of the crossbeam frame assembly 8, and an lifting trolley frame assembly 802 fixedly installed on the other side of the crossbeam frame assembly 8. The lifting trolley frame assembly 802 is movably installed with the side guide rail 2.

[0020] The lifting trolley assembly 802 of the lifting trolley component cooperates with the side guide rail 2, and slides up and down in the column guide rail in this way, so that the lifting trolley component can achieve lifting and lowering action along the side guide rail 2.

[0021] As a technical optimization of this utility model, the lower lifting trolley assembly includes a lifting fork crank arm assembly 901 fixedly installed on one side of the lower lifting trolley assembly 9, and the lower lifting trolley assembly 9 is movably installed with the side guide rail 2.

[0022] The lower lifting trolley assembly 9 of the lower lifting trolley component cooperates with the side guide rail 2 and slides up and down in the column guide rail in this way, so that the lower lifting trolley component can achieve the lifting action along the side guide rail 2.

[0023] As a technical optimization of this utility model, the mesh belt conveyor assembly includes a second roller 12 rotatably installed below one side of the mesh belt conveyor assembly 10, a first roller 11 rotatably installed above the other side of the mesh belt conveyor assembly 10, and a plurality of flat parallel pads 13 are provided above the mesh belt conveyor assembly 10.

[0024] The mesh belt conveyor can receive single-layer sorted boxes from the front-end sorting and box-sorting station, and then the movement of the lifting trolley can be used to move the subsequent whole-layer gripper assembly. The mesh belt conveyor can then transport the boxes into the whole-layer gripper assembly for palletizing.

[0025] As a technical optimization of this utility model, the whole-layer gripper assembly includes a mounting base 15 fixedly installed on the top of the whole-layer gripper assembly 14, a cylinder 16 movably installed on the inner side of the whole-layer gripper assembly 14, a spherical bearing 17 fixedly installed on one side of the whole-layer gripper assembly 14, and an inlet box baffle 18 rotatably installed on the outer side of the spherical bearing 17. The output end of the cylinder 16 is movably connected to one side of the inlet box baffle 18.

[0026] By fixing the entire layer gripper assembly to one side of the lifting trolley assembly, the position of the lifting trolley assembly can be adjusted up and down to achieve the purpose of stacking boxes layer by layer. The cylinder 16 drives the box entry baffle 18 to rotate around the joint bearing 17, so that the box entry baffle 18 can block and intercept the stacked boxes to ensure the stability of stacking.

[0027] Working principle: The main lifting device 6 is symmetrically equipped with servo motors on both sides of the top of the upper column assembly 5, which can provide two sets of power to control the upper lifting trolley assembly and the lower lifting trolley assembly respectively. This allows the upper and lower lifting trolley assemblies to operate independently and ensure their stable operation. The upper and lower lifting trolley assemblies control their relative positions to achieve subsequent palletizing actions. The mesh belt conveyor assembly is installed on the lifting fork crank assembly 901 of the lower lifting trolley assembly. It mainly receives the single-layer sorted boxes from the front-end sorting and box handling station. The movement of the lower lifting trolley assembly then moves the subsequent whole-layer gripper assembly. The mesh belt conveyor assembly transports the boxes into the whole-layer gripper assembly. The whole-layer gripper assembly is fixedly installed on one side of the upper lifting trolley assembly. The position of the upper lifting trolley assembly can be adjusted up and down to achieve the purpose of stacking boxes layer by layer.
