A stacking equipment for aluminum-plastic composite panels

Abstract

This invention discloses an aluminum-plastic composite panel stacking device, comprising a stacking hopper and a base support assembly. The stacking hopper is configured with a first opening and a second opening, and a stacking station and a feeding station are arranged between the first opening and the second opening, with the feeding station being higher than the stacking station. The base support assembly includes a base support frame that circulates along a circular path, and a base support plate is rotatably connected to the base support frame. The base support plate includes a top bearing surface and a bottom bearing surface arranged at an angle. The top bearing surface supports the upstream aluminum-plastic composite panel, and under the gravity of the aluminum-plastic composite panel, the bottom bearing surface is parallel to the stacking station. Thus, as the base support assembly moves to the second opening, the base support plate generates horizontal acceleration, overcoming the static friction between the aluminum-plastic composite panel and the base support plate, causing the base support plate to be pulled out from between the aluminum-plastic composite panel and the stacking station. The aluminum-plastic composite panel gradually loses the support of the top bearing surface and gradually enters the stacking station, thereby ensuring both conveying efficiency and product quality.

Description

Technical Field

[0001] This invention relates to the field of transportation structure technology, and in particular to an aluminum-plastic composite panel stacking equipment. Background Technology

[0002] In modern large-scale production, the processing of sheet metal involves multiple steps. For example, the initially cylindrical sheet material is gradually uncoiled by an uncoiler. During this uncoiling process, the sheet material is fed into subsequent processing equipment for cutting, forming, punching, and other processes to create the desired sheet metal. Because the sheets vary in size and shape, the processed sheets need to be neatly stacked using a stacker crane for easy storage and transportation. Therefore, the stacker crane, as a key component of the transportation structure, is responsible for the orderly stacking of processed sheets to ensure efficient space utilization and prevent deformation or damage during transport.

[0003] Existing stacking equipment typically uses conveyor belts to directly feed sheet metal into the stacking chamber. During this process, multiple sheets fall sequentially from top to bottom, achieving initial stacking. However, for relatively delicate materials like aluminum composite panels, direct drop stacking, due to the uncertainty of the fall, can easily cause localized impacts on the surface of the aluminum composite panels, resulting in indentations that affect aesthetics and performance, ultimately degrading the quality. While using a robotic arm instead of a conveyor belt can achieve stable stacking of aluminum composite panels, the conveying efficiency is lower.

[0004] It is evident that existing stacking equipment cannot guarantee the quality of aluminum-plastic composite panels while maintaining conveying efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum-plastic composite panel stacking device to solve the technical problem that existing stacking devices cannot guarantee the quality of aluminum-plastic composite panels while maintaining conveying efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An aluminum-plastic composite panel stacking device includes a liftable stacking bin, one end of which is provided with a first opening for aluminum-plastic composite panels to enter, and the other end of which is provided with a second opening. A stacking station and a feeding station are provided between the first opening and the second opening, and the feeding station is higher than the stacking station.

[0008] It also includes a base assembly that can move cyclically along a circular path, the circular path including at least a first path from the feeding station to the stacking station, and a second path from the stacking station to the second opening;

[0009] The base support assembly includes a base support frame that moves cyclically along the annular path, the base support frame being rotatably connected to a base support plate, and the base support plate including a top bearing surface and a bottom bearing surface arranged at an angle.

A torsion spring is installed between the buffer shaft and the bottom support plate. A wire unit is wound on the buffer shaft through a winding bobbin. The lower end of the wire unit is fixedly connected to the buffer slider.

[0018] A limit switch is installed on the bottom support plate at one end of the sliding groove near the mounting shaft. When the limit switch is triggered, the negative pressure component is connected to the pressure chamber.

[0019] Optionally, a take-up and release shaft is rotatably connected to the adsorption tank, and the take-up and release shaft is disposed at one end of the sliding tank near the mounting shaft;

[0020] A first roll is also installed on the buffer shaft, and a second roll is installed on the take-up and unwinding shaft. A movable membrane is installed between the first roll and the second roll. One end of the movable membrane is wound into the first roll, and the other end of the movable membrane is wound into the second roll.

[0021] The movable membrane is configured with a sealing area and a clearance area. When the buffer slider is located at the end of the sliding groove away from the mounting shaft, the sealing area of ​​the movable membrane is in contact with the adsorption hole. When the buffer slider is located at the end of the sliding groove close to the mounting shaft, the clearance area of ​​the movable membrane is arranged opposite to the adsorption hole to avoid the adsorption hole.

[0022] Optionally, the bottom support plate is equipped with a bottom limiting member and a side limiting member on the top bearing surface.

[0028] Optionally, the length of the second path is greater than the length of the first path.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The aluminum-plastic composite panel stacking equipment provided by this invention involves a bottom support assembly that moves cyclically along a circular path during the stacking of aluminum-plastic composite panels. In the first path, when the bottom support assembly is located at the feeding station, the aluminum-plastic composite panel can move from the upstream equipment through the first opening to the feeding station and be supported by the top bearing surface. Then, under the gravity of the aluminum-plastic composite panel, the bottom support plate rotates against the force of the reset unit, making the bottom bearing surface parallel to the stacking station. At this time, the aluminum-plastic composite panel and the top bearing surface are set at an inclined angle relative to the stacking station. Then, the bottom support assembly can move along the first path to the stacking station. In the second path, since the aluminum-plastic composite panel and the top bearing surface are set at an inclined angle relative to the stacking station, the bottom support plate generates horizontal acceleration during the movement of the bottom support assembly to the second opening. This overcomes the static friction between the aluminum-plastic composite panel and the bottom support plate, causing the bottom support plate to be pulled out from between the aluminum-plastic composite panel and the stacking station. The aluminum-plastic composite panel gradually loses the support of the top bearing surface and gradually enters the stacking station. Through the above setup, the cyclical movement of the base support assembly continuously receives aluminum-plastic composite panels from upstream, ensuring conveying efficiency. Furthermore, during the removal of the base support, an angled design allows the aluminum-plastic composite panels to gradually enter the stacking station, reducing localized impacts and thus ensuring their quality. Therefore, this aluminum-plastic composite panel stacking equipment can guarantee the quality of aluminum-plastic composite panels while maintaining conveying efficiency. Attached Figure Description

[0044] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments.

[0045] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0046] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] The aluminum-plastic composite panel stacking equipment provided in this embodiment is suitable for production and conveying scenarios of aluminum-plastic composite panels and other panels with high appearance requirements. In this embodiment, the structure of the aluminum-plastic composite panel stacking equipment is improved to ensure its transportation efficiency and to prevent damage to the aluminum-plastic composite panels.

[0048] The aluminum-plastic composite panel stacking equipment provided in this embodiment includes a stacking device 100 and a base support assembly 200 that can circulate along a ring path. During operation, upstream equipment such as cutting equipment, forming equipment, and punching equipment transport aluminum-plastic composite panels to the downstream stacking device 100. For any aluminum-plastic composite panel, it is first horizontally fed into the base support assembly 200 along the entry direction, and then the base support assembly 200 places the aluminum-plastic composite panel into the stacking device 100, thereby ensuring transportation efficiency and product quality.

[0049] like Figure 1 and Figure 2 As shown, the stacking device 100 includes a liftable stacking bin 110. One end of the stacking bin 110 is provided with a first opening 1101 for aluminum-plastic composite panels to enter, and the other end of the stacking bin 110 is provided with a second opening 1102. A stacking station 1103 and a feeding station 1104 are provided between the first opening 1101 and the second opening 1102. The feeding station 1104 is higher than the stacking station 1103. The feeding station 1104 refers to the position where the aluminum-plastic composite panels are just separated from the upstream equipment along the entry direction. A bottom support assembly 200 is provided here as a support. The stacking station 1103 refers to the position where the bottom support assembly 200 is removed to stack the aluminum-plastic composite panels in the stacking bin 110. This position can be the bottom of the stacking bin 110 or the top surface of other aluminum-plastic composite panels, depending on the number of panels to be stacked.

[0050] As the circular path for the movement direction of the base assembly 200, the circular path includes at least a first path from the feeding station 1104 to the stacking station 1103, and a second path from the stacking station 1103 to the second opening 1102; that is, the direction of the first path is perpendicular to the entry direction, while the direction of the second path is parallel to the entry direction.

[0051] Among them, such as Figure 3 and Figure 4 As shown, the base support assembly 200 includes a base support frame 210 that moves cyclically along a circular path. A base support plate 220 is rotatably connected to the base support frame 210. The base support plate 220 includes a top bearing surface 2201 and a bottom bearing surface 2202 arranged at an angle. A reset unit is connected between the base support plate 220 and the base support frame 210, giving the base support plate 220 a tendency to move parallel to the stacking station 1103. Furthermore, when an aluminum-plastic composite panel is provided on the top bearing surface 2201, the bottom bearing surface 2202 is parallel to the stacking station 1103. The above-mentioned parallelism with the stacking station 1103 can be understood as parallelism with the entry direction.

[0052] Specifically, in this embodiment, when the aluminum-plastic composite panel stacking equipment stacks aluminum-plastic composite panels, the bottom support assembly 200 moves cyclically along a circular path.

[0053] In the first path, when the bottom support assembly 200 is located at the feeding station 1104, the aluminum-plastic composite panel can move from the upstream equipment through the first opening 1101 to the feeding station 1104 and be supported by the top bearing surface 2201. Then, under the gravity of the aluminum-plastic composite panel, the bottom support plate 220 rotates against the force of the reset unit, making the bottom bearing surface 2202 parallel to the stacking station 1103. At this time, the aluminum-plastic composite panel and the top bearing surface 2201 are set at an inclined angle relative to the stacking station 1103. Then, the bottom support assembly 200 can move along the first path to the stacking station 1103. It can be understood that this inclined angle is the maximum inclination of the top bearing surface 2201. At an angle, the aluminum-plastic composite panel will not fall from the top bearing surface 2201. Additionally, it should be noted that this embodiment should include a counter, optical sensors, or other structures capable of detecting the number of aluminum-plastic composite panels in the stacking bin 110. This allows for real-time measurement of the overall thickness of the aluminum-plastic composite panels in the stacking bin 110. As the overall thickness increases, the stacking bin 110 should correspondingly decrease in height to maintain the position of the stacking station 1103. That is, as the aluminum-plastic composite panels are stacked, the stacking station 1103 changes from its initial location at the bottom of the stacking bin 110 to the top surface of the topmost stacked aluminum-plastic composite panel, thereby improving overall stability.

[0054] In the second path, since the aluminum-plastic composite panel and the top bearing surface 2201 are set at an inclined angle relative to the stacking station 1103, during the movement of the bottom support assembly 200 to the second opening 1102, the bottom support plate 220 generates horizontal acceleration, overcoming the static friction and other forces between the aluminum-plastic composite panel and the bottom support plate 220. This allows the bottom support plate 220 to be pulled out from between the aluminum-plastic composite panel and the stacking station 1103, while the aluminum-plastic composite panel gradually loses the support of the top bearing surface 2201 and gradually enters the stacking station 1103. Through the above arrangement, the cyclical movement of the bottom support assembly 200 continuously receives aluminum-plastic composite panels from upstream to ensure conveying efficiency. Furthermore, during the extraction of the bottom support plate 220, the inclined angle allows the aluminum-plastic composite panel to gradually enter the stacking station 1103, reducing local impact on the aluminum-plastic composite panel and thus ensuring its quality. Therefore, this aluminum-plastic composite panel stacking equipment can ensure the quality of the aluminum-plastic composite panel while maintaining conveying efficiency.

[0055] As an optional implementation, the reset unit is a torsion spring connected between the bottom support plate 220 and the bottom bracket 210. One end of the torsion spring is connected to the bottom support plate 220 and the other end is connected to the bottom bracket 210 to ensure that when there is no aluminum-plastic composite panel on the top support surface 2201 of the bottom support plate 220, its top support surface 2201 can remain parallel to the inlet direction, so as to reduce the impact when the aluminum-plastic composite panel flows out.

[0056] As an alternative implementation, the reset unit can be connected to a compression spring between the base plate 220 and the base bracket 210. The compression spring provides elastic force, causing the right end of the base plate 220 to be subjected to a leftward elastic force, so that the top bearing surface 2201 can remain parallel to the entry direction. The reset unit can also be a composite structure of a damping spring and a torsion spring (e.g., a torsion spring damper) to achieve stable rotation of the base plate 220, so that the top bearing surface 2201 remains horizontal when the aluminum-plastic composite panel enters the top bearing surface 2201, and the bottom bearing surface 2202 remains horizontal when the aluminum-plastic composite panel leaves the top bearing surface 2201.

[0057] In this embodiment, as Figures 1 to 4 As shown, a circulation component 300 is arranged along a circular path. The circulation component 300 includes a circular unit 310 extending along the circular path and a drive unit 320 that drives the circular unit 310 to move along the circular path. Multiple base support components 200 are spaced apart on the circular unit 310. The number of base support components 200 can be adaptively increased according to the feeding speed of the upstream equipment to ensure transportation efficiency. In this embodiment, two adjacent base support components 200 can overlap in the entry direction. The base plate 220 of one base support component 200 can be lifted by the base bracket 210 of another base support component 200. At this time, the reset unit (torsion spring) allows the base plate 220 to overlap on the base bracket 210 to ensure transportation efficiency. For example, the number of base support components 200 is four, and the distance between any two is greater than the maximum length of the base support components 200.

[0058] As an optional implementation, the annular unit 310 includes a first conveyor belt 311 and a second conveyor belt 312; the drive unit 320 includes four first synchronous pulleys 321 arranged in a rectangular shape, and four second synchronous pulleys 322 arranged in a rectangular shape; the first conveyor belt 311 is sleeved on the first synchronous pulleys 321, and the second conveyor belt 312 is sleeved on the second synchronous pulleys 322; both the first conveyor belt 311 and the second conveyor belt 312 extend along an annular path, and there is a first gap between the first conveyor belt 311 and the second conveyor belt 312 along the entry direction of the aluminum-plastic composite panel. A first slider 331 is installed on the first conveyor belt 311 corresponding to the bottom bracket 210, and a second slider 332 is installed on the second conveyor belt 312 corresponding to the bottom bracket 210. One side of the bottom bracket 210 is rotatably connected to the first slider 331 through a rotating shaft, and the other side of the bottom bracket 210 is rotatably connected to the second slider 332 through a rotating shaft, and there is a first gap between the first slider 331 and the second slider 332 along the entry direction of the aluminum-plastic composite panel.

[0059] It is understandable that the first conveyor belt 311 and the second conveyor belt 312 are offset in the entry direction and have the same size. Therefore, in the first path, one side of the base bracket 210 and the other side of the base bracket 210 form a horizontal support connecting the two conveyor belts, enabling a constant-angle descent. In the subsequent second path, a constant-angle extraction is achieved. It should be added that a first guide rail 341 is provided outside the first conveyor belt 311, and a second guide rail 342 is provided outside the second conveyor belt 312. A first slider 331 is slidably connected to the first guide rail 341, and a second slider 332 is slidably connected to the second guide rail 342. One of the first synchronous pulleys 321 is driven by a first motor 351, and one of the second synchronous pulleys 322 is driven by a second motor 352.

[0060] As another alternative implementation, the ring unit 310 can be a chain structure.

[0061] In this embodiment, the length of the second path is greater than the length of the first path, which can increase the number of base support components 200 to ensure conveying efficiency.

[0062] Furthermore, regarding the specific structure of the base assembly 200, such as Figures 4 to 7 As shown, a movable gap is left between the bottom support plate 220 and the bottom support frame 210. The bottom support frame 210 is provided with a mounting shaft 230, which passes through the movable gap. The bottom support plate 220 extends with a movable part 221, which is sleeved on the outside of the mounting shaft 230. The bottom support frame 210 is also fixedly connected with a limiting unit 240, which is located in the movable gap and has a gap with the bottom support plate 220. With the setting of the limiting unit 240, when the bottom bearing surface 2202 is parallel to the stacking station 1103, the limiting unit 240 abuts against the bottom support plate 220, thereby preventing the bottom support plate 220 from continuing to rotate downward and preventing indentation on the aluminum-plastic composite panel.

[0063] Furthermore, the bottom support plate 220 has an adsorption groove 222 on the bottom bearing surface 2202, and a plurality of adsorption holes 223 are formed on the bottom wall of the adsorption groove 222, which extend to the top bearing surface 2201; an air chamber assembly 400 is installed in the adsorption groove 222, and the air chamber assembly 400 is configured with a pressure chamber 401. The pressure chamber 401 is connected to all the adsorption holes 223, and the pressure chamber 401 is connected to a negative pressure assembly and a positive pressure assembly. The negative pressure assembly and the positive pressure assembly are alternately connected to the pressure chamber 401 through a solenoid valve.

[0064] For example, when the aluminum-plastic composite panel is fully inserted into the top bearing surface 2201, the negative pressure component is connected to the pressure chamber 401 to generate negative pressure, thereby adsorbing the aluminum-plastic composite panel onto the top bearing surface 2201; when the bottom support component 200 is pulled out along the second path, the positive pressure component is connected to the pressure chamber 401 to generate positive pressure, creating an air gap between the aluminum-plastic composite panel and the top bearing surface 2201, thereby promoting the separation of the aluminum-plastic composite panel.

[0065] Among them, the negative pressure component (vacuum pump), the positive pressure component (air pump) and the solenoid valve are all common pneumatic components. The negative pressure component can draw air, the positive pressure component can expel air, and the solenoid valve can switch between the negative pressure component and the positive pressure component. These are well known to those skilled in the art and will not be elaborated on in this embodiment.

[0066] Furthermore, such as Figures 5 to 8 As shown, along the entry direction of the aluminum-plastic composite panel, the bottom support plate 220 has a sliding groove 224 on at least one side of the adsorption hole 223, and a buffer slider 250 is slidably connected to the sliding groove 224; a buffer shaft 260 is also rotatably connected in the adsorption groove 222, and the buffer shaft 260 is located at the end of the sliding groove 224 away from the mounting shaft 230; a torsion spring is installed between the buffer shaft 260 and the bottom support plate 220, and a wire unit is wound on the buffer shaft 260 through a winding bobbin, and the lower end of the wire unit is fixedly connected to the buffer slider 250; a limit switch is installed on the bottom support plate 220 at the end of the sliding groove 224 near the mounting shaft 230. When the limit switch is triggered, the negative pressure component is connected to the pressure chamber 401, that is, the limit switch triggers the solenoid valve to realize the switching.

[0067] For example, when the aluminum-plastic composite panel enters the top bearing surface 2201, the internal pressure of the pressure chamber 401 is atmospheric pressure. The aluminum-plastic composite panel pushes the buffer slider 250, which drives the buffer shaft 260 to rotate against the force of its torsion spring through the wire unit and winding drum, thereby decelerating the aluminum-plastic composite panel. After the buffer slider 250 is in position, the limit switch is triggered, which in turn triggers the solenoid valve, connecting the negative pressure component with the pressure chamber 401 to generate negative pressure. This negative pressure is applied to the aluminum-plastic composite panel, thus adsorbing it onto the top bearing surface 2201 and improving stability. Simultaneously, when the bottom support plate 220 is pulled away along the second path, under the action of the bottom support plate 220 and the torsion spring, the aluminum-plastic composite panel and the buffer slider 250 separate from the limit switch. The solenoid valve switches, connecting the positive pressure component with the pressure chamber 401 to generate positive pressure and promote the separation of the aluminum-plastic composite panel.

[0068] Furthermore, a take-up and release shaft 270 is rotatably connected to the adsorption tank 222, and the take-up and release shaft 270 is located at one end of the sliding groove 224 near the mounting shaft 230; a first roll 281 is also installed on the buffer shaft 260, and a second roll 282 is installed on the take-up and release shaft 270. A movable membrane 290 is installed between the first roll 281 and the second roll 282. One end of the movable membrane 290 is wound into the first roll 281, and the other end of the movable membrane 290 is wound into the second roll 282. The movable membrane 290 is configured with a sealing area and a clearance area. When the buffer slider 250 is located at the end of the sliding groove 224 away from the mounting shaft 230, the sealing area of ​​the movable membrane 290 is in contact with the adsorption hole 223. When the buffer slider 250 is located at the end of the sliding groove 224 near the mounting shaft 230, the clearance area of ​​the movable membrane 290 is opposite to the adsorption hole 223 to avoid the adsorption hole 223. The sealing area of ​​the movable membrane 290 is a complete membrane body, while the clearance area of ​​the movable membrane 290 has at least a number of strip grooves, with clearance adsorption holes 223 corresponding to the strip grooves. The main body of the movable membrane 290 is located in the second roll 282, and one end of it is tightly wound onto the buffer shaft 260 in the first roll 281. When the aluminum-plastic composite panel has not entered the top bearing surface 2201, the sealing area and the adsorption holes 223 should be positioned opposite each other, and the clearance area is housed in the second roll 282.

[0069] For example, when the aluminum-plastic composite panel enters the top bearing surface 2201, it pushes the buffer slider 250. The buffer slider 250 drives the buffer shaft 260 to rotate through the wire unit, i.e., the winding spool. At this time, the buffer shaft 260 provides buffering for the aluminum-plastic composite panel through its torsion spring, and at the same time, it rotates, thereby pulling the movable membrane 290 and pulling out the avoidance area. When the buffer slider 250 is located at the end of the sliding groove 224 near the mounting shaft 230, the limit switch is triggered, and the sealing area of ​​the movable membrane 290 fits with the adsorption hole 223, realizing the adsorption of the aluminum-plastic composite panel. When the aluminum-plastic composite panel leaves the top bearing surface 2201, the sealing area is reset by the winding action of the movable membrane 290 itself. This reduces the amount of dust entering the interior, extends the working time, improves the conveying efficiency, reduces the impact of dust on the aluminum-plastic composite panel, and also has the advantage of compact structure.

[0070] It should be added that, such as Figure 6 As shown, a bottom limiting member 510 and a side limiting member 520 are installed on the top bearing surface 2201 of the bottom support plate 220. The bottom limiting member 510 is located at one end of the sliding groove 224 near the mounting shaft 230, and the side limiting member 520 is located on the side of the sliding groove 224 away from the adsorption hole 223. The bottom limiting member 510 and the side limiting member 520 form a limiting groove for the aluminum-plastic composite panel to enter.

[0071] It should be added that, such as Figure 1 and Figure 2As shown, a stacking support 120 is provided on the outside of the stacking silo 110, and the stacking silo 110 and the stacking support 120 are slidably connected. A lifting motor 130 is installed at the bottom of the stacking support 120, and a fixed pulley group 140 is installed at the top of the stacking support 120. The motor shaft of the lifting motor 130 is wound with a lifting cable through a lifting cylinder, and the end of the lifting cable passes around the fixed pulley group 140 and connects to the stacking silo 110. At the same time, a traveling track 170 is also provided below the stacking support 120. The stacking support 120 is driven by a traveling motor 150 and the traveling wheels 160 enable the stacking silo 110 to move freely along the traveling track 170.

[0072] It should be added that, such as Figure 8 As shown, a wiring hole 225 is also provided on the wall of the adsorption tank 222. The pipeline structure of the positive pressure component and the negative pressure component can pass through the slip ring and then connect to the pressure chamber 401 through the wiring hole 225, which has the advantage of compact structure.
