Description

Technical Field

[0001] This utility model relates to a single-column palletizer, specifically a new type of lifting device for a single-column palletizer. Background Technology

[0002] Single-column palletizers are essential handling equipment in warehouses, primarily used for stacking and retrieving heavy items. They consist of a column, lifting device, clamps, and a control system. The lifting device vertically transports goods to a designated location, and then the clamps place the goods in the required position.

[0003] Referring to the Chinese authorized patent, publication number CN113979113B, publication date 2022-03-15, a single-column linkage automatic palletizing machine is disclosed.

[0004] Current single-column palletizer lifting devices typically use linear guides to achieve reciprocating lifting at the palletizer's end effector. Linear guides, as high-precision, high-rigidity linear motion components, are expensive to manufacture and difficult to maintain. They achieve low-friction motion through rolling elements (balls or rollers), but the small contact area between the rolling elements and the guide surface easily leads to localized stress concentration, thus limiting their load-bearing capacity. Furthermore, linear guides require extremely high precision from the mounting surface, causing installation inconvenience, and installation errors can severely impact the lifespan and operating efficiency of the linear guide. Utility Model Content

[0005] The purpose of this invention is to provide a novel lifting device for a single-column palletizer to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel single-column palletizer lifting device, comprising a guide wheel moving module slidably disposed on a single column, the guide wheel moving module being driven to move by a lifting mechanism mounted on the single column, and contacting the single column to lock it through a cylinder-driven clamp plate movably disposed thereon;

[0007] The lifting mechanism includes at least a fixed pulley and a timing belt mounted on the fixed pulley and fixedly connected to the guide wheel moving module. The other end of the timing belt is fixedly connected to a counterweight block that is slidably installed inside the single column.

[0008] Preferably, a main double guide rail component is fixedly installed on the front of the single column, and the guide wheel moving module includes first guide wheels that are symmetrically distributed and rolledly connected about one side of the main double guide rail component.

[0009] Preferably, the single column is fixedly installed with side wing double guide rail components on both sides, and the guide wheel moving module includes at least two second guide wheels on one side that are arranged to rotate vertically, and the second guide wheels are rolledly connected to the track on one side of the side wing double guide rail components.

[0010] Preferably, the number of guide wheel moving modules is at least two, and a U-shaped connecting plate is fixedly installed between the two.

[0011] Preferably, the lifting mechanism includes a drive motor fixedly mounted on the motor mounting base at the top of the single column, and the drive motor is used to drive the fixed pulley.

[0012] Preferably, the synchronous belt is led out from the perforated groove on the main double guide rail and is tactilely connected to the driven synchronous wheel fixedly installed inside the main double guide rail.

[0013] Preferably, limiters are fixedly installed at both ends of the main double guide rail, and the limiters include rubber contact blocks that abut against the guide wheel moving module.

[0014] Preferably, a connecting seat is fixedly installed on the guide wheel moving module, one end of the clamping plate is rotatably disposed on the connecting seat, and the other end is slidably disposed in the waist groove opened on the connecting seat.

[0015] Preferably, one end of the clamping plate is fixedly provided with an inclined guide portion, a bottom groove and an arc-shaped blocking portion distributed from the adjacent side of the single column to the other side, and the bottom groove abuts against any groove on the groove plate fixedly installed on the front of the main double guide rail component.

[0016] In the above technical solution, the novel single-column palletizer lifting device provided by this utility model has the following beneficial effects: the lifting of the palletizer's execution end is achieved through the rolling cooperation between the guide wheel assembly and the guide plate, replacing the traditional linear guide rail structure. This design not only significantly reduces manufacturing and daily maintenance costs, but also simplifies the installation process and improves installation convenience.

[0017] In addition, the contact method between the guide wheel and the guide surface improves the force distribution and reduces the problem of local stress concentration, thereby effectively improving the load-bearing capacity of the entire palletizing machine and making it more suitable for heavy-duty working conditions.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 The present invention provides a technical solution: a novel single-column palletizer lifting device, including a guide wheel moving module 2 slidably disposed on a single column 1. The guide wheel moving module 2 is driven to move by a lifting mechanism assembled on the single column 1, and contacts the single column 1 to lock through a clamping plate 4 movably disposed thereon and driven by a cylinder 3.

[0027] The lifting mechanism includes at least a fixed pulley 21 and a synchronous belt 22 mounted on the fixed pulley 21 and fixedly connected to the guide wheel moving module 2. The other end of the synchronous belt 22 is fixedly connected to a counterweight block 23 that is slidably installed in the single column 1.

[0028] Specifically, the aforementioned fixed pulley 21 is a synchronous pulley installed on the shaft at the top of the single column 1, and the shaft is connected to the drive motor 26 fixedly installed on the motor mounting base at the top of the single column 1, thereby driving the synchronous belt 22 to move, and thus realizing the movement of the control guide wheel moving module 2.

[0029] The aforementioned guide wheel moving module 2 is fixed to the single column 1 by installing guide wheels. It includes at least guide wheels that are symmetrically and rollingly connected to the guide rail groove on the side wall of the single column 1, or the single column 1 has a guide rail groove on the front, and the guide wheels are located on the guide rail groove, or a combination of the above two methods.

[0030] Furthermore, the aforementioned clamping plate 4 is pushed by the cylinder 3 (the contact surface of the clamping plate 4 is a rubber surface), thereby abutting against the side wall of the single column 1 or the groove opened in the side wall of the single column 1, and there are multiple grooves, which are distributed vertically.

[0031] In the aforementioned technology, the lifting and lowering of the palletizer's execution end (i.e., the guide wheel moving module 2) is achieved through the rolling cooperation between the guide wheel assembly and the guide plate (i.e., the guide wheel moving module 2), replacing the traditional linear guide rail structure. This design not only significantly reduces manufacturing and daily maintenance costs but also simplifies the installation process and improves installation convenience.

[0032] In addition, the contact method between the guide wheel and the guide surface improves the force distribution and reduces the problem of local stress concentration, thereby effectively improving the load-bearing capacity of the entire palletizing machine and making it more suitable for heavy-duty working conditions.

[0033] As a further embodiment of this utility model, combined with Figure 1 As shown, a main double guide rail component 11 is fixedly installed on the front of the single column 1, and the guide wheel moving module 2 includes a first guide wheel 24 that is symmetrically distributed and rolledly connected about one side of the track center of the main double guide rail component 11.

[0034] Specifically, in this embodiment, the first guide wheel 24 is fixedly installed on the sheet metal rolling bearing of the guide wheel moving module 2. The installation method adopted is that the shaft of the first guide wheel 24 passes through the inner ring of the rolling bearing, and is then fixed on the inner ring of the rolling bearing by means of a nut (anti-loosening nut) and threaded connection with the shaft, thereby forming a disassembly structure.

[0035] Furthermore, the aforementioned first guide wheel 24 can be rolled to the adjacent surfaces of the double rails of the main double guide rail component 11, or it can be rolled to one side about a single rail, and in this state it needs to be symmetrically distributed with the clamping plate 4 and the drive structure.

[0036] As another embodiment further provided by this utility model, combined with Figure 1 As shown, the single column 1 is fixedly installed with side wing double guide rail components 12 on both sides. The guide wheel moving module 2 includes at least two second guide wheels 25 arranged vertically on one side. The second guide wheels 25 are rolledly connected to the track on one side of the side wing double guide rail component 12.

[0037] Furthermore, the number of guide wheel moving modules 2 is at least two, and a U-shaped connecting plate 5 is fixedly installed between them.

[0038] Specifically, based on the above embodiments, the second guide wheel 25 in the embodiments is fixedly installed on the sheet metal rolling bearing of the guide wheel moving module 2, and the installation method adopted is that the shaft of the second guide wheel 25 passes through the inner ring of the rolling bearing, and is then fixed on the inner ring of the rolling bearing by means of a nut (anti-loosening nut) and threaded connection with the shaft, thereby forming a disassembly structure.

[0039] The second guide wheel 25 is distributed on the two adjacent sides of the first guide wheel 24 about the single column 1.

[0040] As another embodiment of the present invention, the synchronous belt 22 is led out from the perforated groove on the main double guide rail 11 and is tactilely connected to the driven synchronous wheel 27 fixedly installed inside the main double guide rail 11.

[0041] The synchronous belt 22 is installed and fixed to the guide wheel moving module 2 by sheet metal and bolts after passing through the driven synchronous pulley 27.

[0042] Furthermore, during actual operation, limiters 6 are fixedly installed at both ends of the main double guide rail component 11. Each limiter 6 includes a rubber contact block 61 that abuts against the guide wheel moving module 2. The purpose is to limit the vertical path length of the guide wheel moving module 2, while the driven synchronous wheel 27 is higher than the height of the limiter 6 located on the upward path.

[0043] As another embodiment of this utility model, a connecting seat 7 is fixedly installed on the guide wheel moving module 2, one end of the clamping plate 4 is rotatably disposed on the connecting seat 7, and the other end is slidably disposed in the waist groove 71 opened on the connecting seat 7.

[0044] Specifically, during actual operation, the cylinder 3 drives the clamping plate 4 to move at one end connected to the waist groove 71, and swings around the other end's rotation point as the origin, thereby locking against the single column 1.

[0045] As a further preferred embodiment of this utility model, one end of the clamping plate 4 is fixedly provided with an inclined guide portion 41, a bottom groove 42 and an arc-shaped blocking portion 43 distributed from one side adjacent to the single column 1 to the other side. The bottom groove 42 abuts against any groove on the slot plate 111 fixedly installed on the front of the main double guide rail component 11.

[0046] Specifically, when there are several slots, they are arranged in a linear array along the slot plate 111. When the cylinder 3 drives the clamping plate 4 to move, the inclined guide part 41 passes through the slot, causing the bottom groove 42 to abut against the bottom of the slot, thereby forming a blockage and enabling the guide wheel moving module 2 to hover.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
