Description

Technical Field

[0001] This utility model belongs to the field of material frame stacking equipment, specifically relating to a high-rise material frame stacking machine. Background Technology

[0002] Currently, the production and processing of aluminum materials generally adopts extrusion molding. When using this extrusion molding process to produce aluminum materials, the raw materials (usually aluminum rods or ingots, etc.) softened at high temperature are first placed in an extruder, and then extruded through an aluminum extrusion die under strong pressure to form a shape that meets the design requirements. Subsequently, after extrusion molding is completed, the aluminum material needs to be cut into specific lengths and then proceed to subsequent processes such as aging treatment and coating.

[0003] Furthermore, during the transfer of aluminum materials, which are relatively soft and prone to deformation, they need to be placed in a pallet crate for protection. Simultaneously, to reduce the labor intensity of workers and improve the efficiency of pallet stacking, existing aluminum processing production lines are gradually adopting various types of stacking machines to automate the stacking of pallets. For example, Chinese patent CN113955503A discloses an automatic pallet conveying and stacking machine.

[0004] However, existing stacking machines, in their design of lifting mechanisms to reduce the number of lifting motors, often suffer from complex transmission structures and significant energy losses. For example, the aforementioned automatic pallet conveyor stacking machine, in its designed lifting structure, uses a four-stage transmission structure between the four sets of lifting chains to ensure synchronous lifting. Each transmission structure is arranged on one of the four sides of the gantry, and the lifting reduction motor is located at one end of one of the synchronous shafts. Therefore, its entire lifting mechanism's transmission structure not only suffers from structural complexity but also from large space occupation and significant energy losses. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing stacking machines, such as complex transmission structures, high energy loss, and large space occupation, by proposing and designing an elevated material frame stacking machine that can not only realize the material frame stacking action, but also has the advantages of simple transmission structure, small space occupation, and low energy consumption.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a high-level material frame stacking machine, comprising a stacking platform, four columns at the lower end of the stacking platform, each column having a material gripping mechanism vertically slidably mounted on it, and each material gripping mechanism being connected to a chain; a dual-output shaft drive motor at the upper end of the stacking platform, each of the two output shafts of the dual-output shaft drive motor being driven by a drive shaft, and both drive shafts being driven by a chain drive shaft at their ends, with a drive sprocket one and a drive sprocket two mounted on the chain drive shaft; the stacking platform... Two driven chain shafts (first and second) are rotatably mounted at the upper end. The first driven chain shafts are located above two of the columns, and each driven chain shaft has a driven sprocket (first). The second driven chain shafts are located above the other two columns, and each driven chain shaft has a driven sprocket (second). The ends of the chains connected to the two material gripping mechanisms pass sequentially around the corresponding driven sprocket (first) and driving sprocket (first) before connecting to a counterweight. The ends of the chains connected to the other two material gripping mechanisms pass sequentially around the corresponding driven sprocket (second) and driving sprocket (second) before connecting to a counterweight. In this high-mounted material frame stacking machine provided by this utility model, the corresponding frame stacking action can be achieved through the cooperation of the above-mentioned transmission structure and the four material gripping mechanisms. Furthermore, the entire transmission structure can be simplified by changing the transmission relationship and layout of each transmission component, thereby achieving the purpose of simplifying the overall structure, reducing space occupation, and reducing energy consumption.

[0007] Furthermore, the material gripping mechanism includes a vertical sliding sleeve, which is fitted onto a corresponding column, and the upper end of the vertical sliding sleeve is fixedly connected to a corresponding chain. A lifting mounting plate is installed on the outer side of the vertical sliding sleeve, and a bearing sleeve is installed on the lifting mounting plate. A lifting shaft is horizontally slidably installed inside the bearing sleeve. One end of the lifting shaft can extend out of the bearing sleeve, and the other end of the lifting shaft is connected to a linear drive component. The linear drive component is used to control the horizontal sliding of the lifting shaft inside the bearing sleeve, so that the lifting shaft can both extend to the outside of the lifting mounting plate to engage with the material to be lifted, and retract to the top of the lifting mounting plate to separate from the material to be lifted.

[0008] Furthermore, the vertical sliding sleeve includes a lifting splicing plate, a lifting side plate, and a chain tensioning mounting plate located on the outside of the column. The lifting splicing plate, the first lifting side plate, the chain tensioning mounting plate, and the second lifting side plate are connected end to end in sequence, and the upper end of the chain tensioning mounting plate is connected to the corresponding chain. Rollers are provided on the inner side of the lifting side plate, and the rollers make rolling contact with the side of the column. A lifting mounting plate is installed on the outer side of the lifting side plate. Moreover, the vertical sliding sleeve preferably uses roller bearings with eccentric sleeves as rollers. In this way, it can adjust the contact area on one side through the roller bearings. That is, when there is an eccentric load in the material frame waiting to lift material, the gap between the vertical sliding sleeve and the column can be adjusted by the eccentric roller structure, thereby ensuring that the vertical sliding sleeve can slide smoothly.

[0009] Furthermore, the linear drive includes a drive cylinder, the cylinder body of which is mounted on the lifting mounting plate via a cylinder head trunnion fixing seat, and the piston rod of the drive cylinder is fixedly mounted on the end of the lifting shaft via a connecting rod, and can drive the lifting shaft to move horizontally together.

[0010] Furthermore, the material gripping mechanism also includes a hook fixing plate. The lower end of the hook fixing plate is provided with a material connecting part, and the upper end of the hook fixing plate is provided with a hook. When it is necessary to use this utility model to stack materials such as material frames that do not have lifting parts, a corresponding number of hook fixing plates can be set on both sides of each material to be stacked, and the distance between the hooks is the same as the distance between each lifting shaft, so as to ensure that the material can be lifted by each material gripping mechanism.

[0011] Furthermore, a lifting link connects the two material gripping mechanisms on the front side and the two material gripping mechanisms on the rear side, and the lifting link ensures the synchronization between the two material gripping mechanisms on the same side.

[0012] Furthermore, a lifting frame is connected between the two lifting rods. The lifting frame is located below the stacking platform and is used to ensure that the four material gripping mechanisms can be lifted and lowered synchronously, as well as to limit and constrain the stacked material frames to prevent them from shaking significantly during the lifting process.

[0013] Furthermore, the counterweight connected to the chain is located below the rear end of the stacking platform, and a protective cover is installed on the rear side of the column at the rear end of the stacking platform via a protective cover support block. The counterweight is located inside the protective cover and is protected by the protective cover.

[0014] Furthermore, a guardrail is installed at the top of the stacking platform to provide safety protection.

[0015] As can be seen from the above technical solutions, this utility model has the following advantages: The elevated material frame stacking machine provided by this utility model can realize the corresponding frame material stacking action through the cooperation of the above transmission structure and the four material grabbing mechanisms. It can also simplify the entire transmission structure by changing the transmission relationship and layout position of each transmission component, thereby achieving the purpose of simplifying the overall structure, reducing the space occupied, and reducing energy consumption. At the same time, it can also be connected in series between the aluminum extrusion production line and the aging furnace, making the production of the aluminum extrusion production line smoother, thereby improving production efficiency.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figures 1 to 4This utility model provides an elevated material frame stacking machine, which includes a stacking platform 1. The lower end of the stacking platform 1 is provided with four columns 2, which are arranged in a 2×2 rectangular array. Each column 2 is vertically and slidably installed with a material gripping mechanism 9.

[0024] like Figure 4 As shown, the material gripping mechanism 9 includes a vertical sliding sleeve, which is composed of a lifting splicing plate 23, a first lifting side plate 22, a chain tensioning mounting plate 33, and a second lifting side plate 22 connected end to end in sequence, and vertically slidingly mounted on the corresponding column 2. Furthermore, the upper end of the chain tensioning mounting plate 33 is connected to a chain via a chain connector 32. Rollers 34 are provided on the inner side of the lifting side plate 22, and the rollers 34 roll in contact with the side of the column 2 to reduce friction between the column 2 and the vertical sliding sleeve. A lifting mounting plate 24 is installed on the outer side of the lifting side plate 22, and a bearing sleeve 29 and a linear drive component are installed on the lifting mounting plate 24. A lifting shaft 28 is horizontally slidably mounted inside the bearing sleeve 29, allowing the lifting shaft 28 to both extend out of the bearing sleeve 29 to engage with the material to be lifted, and also to move away from the material to be lifted, thus separating from it. The linear drive is used to control the horizontal sliding of the lifting shaft 28 within the bearing sleeve 29. Specifically, in this embodiment, the linear drive includes a drive cylinder 26. The cylinder body of the drive cylinder 26 is mounted on the lifting mounting plate 24 via a cylinder head trunnion fixing seat 25. The piston rod of the drive cylinder 26 is fixedly mounted to the end of the lifting shaft 28 via a connecting rod 27, and can drive the lifting shaft 28 to move horizontally together, so that the lifting shaft 28 can extend to the outside of the lifting mounting plate 24 and retract to the top of the lifting mounting plate 24. In addition to the drive cylinder 26, the linear drive can also employ mechanisms capable of outputting linear motion, such as electric push rods or hydraulic cylinders.

[0025] Furthermore, as a preferred embodiment, the material gripping mechanism 9 of this invention also includes a hook fixing plate 31. The lower end of the hook fixing plate 31 is provided with a material connecting part, which can be installed on the material to be lifted. The upper end of the hook fixing plate 31 is provided with a hook 30, which can be inserted into the lifting shaft 28 to achieve the connection between the material to be lifted and the lifting shaft 28. When it is necessary to use this invention to stack materials such as the material frame 8 that do not have lifting parts, a corresponding number of hook fixing plates 31 can be set on both sides of each material to be stacked, and the distance between the hooks 30 is the same as the distance between each lifting shaft 28, thereby ensuring that the material can be lifted by each material gripping mechanism 9.

[0026] Meanwhile, the four material gripping mechanisms 9 are connected by a lifting frame 6 that is closed on all four sides and open at the bottom. The lifting frame 6 is located below the stacking platform 1, and a lifting connecting rod 7 is provided on the front and rear sides of the lifting frame 6. The two ends of the lifting connecting rod 7 on the front side are connected to the two material gripping mechanisms 9 located on the front side of the lifting frame 6, and the two ends of the lifting connecting rod 7 on the rear side are connected to the two material gripping mechanisms 9 located on the rear side of the lifting frame 6. In this way, the lifting frame 6 can limit and constrain the stacked material frame 8, and the lifting frame 6 and the lifting connecting rod 7 can ensure the synchronization between the four material gripping mechanisms 9, so as to avoid the material being lifted from shaking significantly during the lifting process.

[0027] like Figure 1 , Figure 2 As shown, a synchronous transmission mechanism 5 is provided at the rear end of the upper surface of the stacking platform 1. The synchronous transmission mechanism 5 includes a dual-output shaft drive motor 10 located in the middle of the stacking platform 1. Each of the two output shafts of the dual-output shaft drive motor 10 is driven by a drive shaft 12. The drive shafts 12 are rotatably mounted on the stacking platform 1 via bearing seats 11, and each end of the two drive shafts 12 is driven by a sprocket transmission mechanism 21. Figure 3 As shown, the two sprocket drive mechanisms 21 are respectively installed at the left and right ends of the upper surface of the stacking platform 1. Each sprocket drive mechanism 21 includes two sprocket bases 18 installed on the upper surface of the stacking platform 1. The two sprocket bases 18 are respectively located above the two columns 2 on corresponding sides. The sprocket base 18 located above the rear column 2 is rotatably mounted with a chain drive shaft 16 and a chain driven shaft 2 via a bearing 14. The sprocket base 18 located above the front column 2 is rotatably mounted with a chain driven shaft 1 via a bearing 14. The chain drive shaft 16 is connected to the end of the corresponding drive shaft 12 via a coupling, and both a drive sprocket 13 and a drive sprocket 2 are fixedly mounted on the chain drive shaft 16. The chain driven shaft 1 is located above the front column 2, and each chain driven shaft 1 is equipped with a driven sprocket 19. The second driven chain shaft is located above the rear column 2, and each second driven chain shaft is equipped with a second driven sprocket 15.

[0028] Meanwhile, the chains connected to the two material gripping mechanisms 9 located at the front column 2 are both longer first chains 17, and the ends of the first chains 17 successively pass over the corresponding driven sprocket 19 and driving sprocket 13 before connecting to the counterweight. The chains connected to the two material gripping mechanisms 9 located at the rear column 2 are both shorter second chains 20, and the ends of the second chains 20 successively pass over the driven sprocket 15 and driving sprocket 2 before connecting to the counterweight. At this time, under the action of the dual output shaft drive motor 10, the corresponding two first chains 17 and two second chains 20 can be controlled to move synchronously, thereby controlling the four material gripping mechanisms 9 to synchronously drive the gripped materials to rise and fall.

[0029] Furthermore, as a preferred embodiment, this invention also includes a protective cover 3 installed on the rear side of the column 2 located at the rear end of the stacking platform 1 via a protective cover support block 4, and the counterweight is placed inside the protective cover 3, thereby protecting it through the protective cover 3. A guardrail 35 is provided at the upper end of the stacking platform 1, and the guardrail 35 serves the purpose of safety protection.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
