Description

Technical Field

[0001] This application relates to the technical field of gypsum board production equipment, and in particular to a stacking device for paper-faced gypsum board. Background Technology

[0002] Paper-faced gypsum board is a type of board made primarily from building gypsum, with appropriate additives and fibers added to form the core, and a specially made paper surface. It is characterized by its lightweight, sound insulation, heat insulation, strong processing performance, and simple construction methods. Paper-faced gypsum board can be divided into four categories: ordinary, water-resistant, fire-resistant, and moisture-proof.

[0003] Currently, gypsum board production lines have a high level of automation. During the production process, workers only need to assist in adjusting the gypsum boards at some process handover points. At the end of the gypsum board production line, the produced gypsum boards need to be unloaded, stacked, and packaged. In the existing unloading and stacking process, especially for small-scale enterprises, manual stacking is generally used. Typically, pallets are placed on the ground at the end of the production line, and two workers lift the gypsum boards transported by the conveyor device onto the pallets. The advantage is that the cost is low, but the disadvantage is that the stacking efficiency is low and the workload of workers is large. Utility Model Content

[0004] To improve palletizing efficiency and reduce worker workload, this application provides a palletizing device for paper-faced gypsum board.

[0005] This application provides a stacking device for paper-faced gypsum board, which adopts the following technical solution: A stacking device for paper-faced gypsum board includes a conveying assembly for conveying gypsum board and a stacking mechanism disposed on the conveying assembly. The stacking mechanism includes a placement frame disposed above the conveying assembly and a lifting assembly disposed below the conveying assembly. The placement frame is used to place processed gypsum board, and the lifting assembly automatically lifts the processed gypsum board onto the placement frame.

[0006] By adopting the above technical solution, mechanical equipment can be used to stack the processed gypsum boards during the stacking process. The processed gypsum boards are transported to the stacking mechanism by the conveying component, and the lifting component lifts the gypsum boards away from the conveying component and lifts them onto the placement rack for stacking. This avoids manual stacking and reduces the workload of workers.

[0007] Optionally, the conveying assembly includes a conveying frame, multiple conveying rollers rotatably mounted on the conveying frame, and a power source for controlling the rotation of the multiple conveying rollers. The processed gypsum board is slidably mounted on the multiple conveying rollers, allowing the gypsum board to be conveyed to the position of the lifting assembly.

[0008] By adopting the above technical solution, the processed gypsum board can be conveyed to the lifting component by the conveyor rollers. The entire process is operated by mechanical power equipment, avoiding the need for manual movement and improving work efficiency.

[0009] Optionally, the lifting assembly includes a lifting cylinder mounted on the conveyor frame and a lifting plate fixed to the end of the lifting cylinder. The lifting plate passes through the middle of two adjacent conveyor rollers and abuts against the plasterboard.

[0010] By adopting the above technical solution, the lifting cylinder is used directly to control the lifting of the gypsum board conveying roller. It has the advantages of timely response and the ability to lift a large weight. It is also more convenient to operate and to carry out maintenance in the future. During the lifting process, the gypsum board is lifted by the lifting plate, which increases the contact area with the gypsum board and avoids the gypsum board from breaking.

[0011] Optionally, the lifting assembly further includes a support plate disposed between the lifting plate and the end of the lifting cylinder. The support plate is in the same length direction as the plasterboard, and multiple lifting plates are vertically fixed in the length direction of the support plate, with the upper ends of the multiple lifting plates simultaneously abutting against the plasterboard.

[0012] By adopting the above technical solution, since the gypsum board is relatively long, multiple evenly arranged lifting plates can apply force to the gypsum board at the same time, increasing the contact area with the gypsum board and preventing the gypsum board from breaking during the lifting process. The set support plate facilitates the connection and fixation of multiple lifting plates with the lifting cylinder.

[0013] Optionally, the placement frame includes a pair of support rods symmetrically arranged on both sides of the gypsum board and arranged in parallel, and a pair of placement rods vertically fixed on each support rod. The two support rods are arranged on the conveyor frame and along the length of the gypsum board. A support block is rotatably arranged on the placement rod near the support rod. The support block can only rotate upward in one direction, and the support block is initially in a horizontal state. The edge of the gypsum board can be supported on multiple support blocks.

[0014] By adopting the above technical solution, the gypsum boards to be stacked can be placed between two sets of placement rods, and multiple support blocks are used to suspend and support the gypsum boards on the placement rods. When stacking the support boards, the edges of the gypsum boards in the raised state can lift the support blocks and cause the support blocks to rotate until the gypsum boards pass the support blocks. After the gypsum boards pass the support blocks, the support blocks return to their initial state under the action of gravity, so that the four edges of the gypsum boards overlap the corresponding support blocks, thereby allowing the gypsum boards to be stacked on the placement rack. During the stacking process, the gypsum boards are stacked sequentially from bottom to top.

[0015] Optionally, an elastic sheet is fixed on the placement rod at a position above the support block, and the elastic sheet can be pressed against the support block.

[0016] By adopting the above technical solution, when the gypsum board passes the support block, the support block can quickly return to its initial state under the action of the elastic sheet, avoiding the inability of the support block to reset in time after rotating into a vertical state after unidirectional rotation.

[0017] Optionally, the conveyor frame is provided with a moving assembly for controlling the relative movement of two support rods. The moving assembly includes a pair of fixed rods spanning across the conveyor frame and a control component for controlling the movement of the support rods. The support rods are slidably fitted onto the fixed rods. The control component includes a rotating screw rotatably mounted on the conveyor frame. The length direction of the rotating screw is the same as that of the fixed rods. The rotating screw is provided with bidirectional threads, and the bidirectional threads on the rotating screw are respectively threaded into the two support rods.

[0018] By adopting the above technical solution, the two support rods can slide and engage with the fixed rod, thereby facilitating the adjustment of the distance between the two sets of placement rods so that plasterboard of different specifications and sizes can be installed. When controlling the relative movement of the two support rods, the rotation of the rotating screw is controlled to make the two support rods move closer or further apart. The manual control method facilitates subsequent maintenance.

[0019] Optionally, a baffle is fixed at the tail end of the conveyor frame to prevent the plasterboard from moving further.

[0020] By adopting the above technical solution, the baffle can play a positioning role. When the gypsum board to be stacked comes into contact with the baffle, it proves that the gypsum board has moved to the correct position, and then the gypsum board is lifted by the lifting component.

[0021] Optionally, inclined guide plates are fixed to the ends of the two support rods away from the baffle, and the two guide plates are arranged in an outward V-shape.

[0022] By adopting the above technical solution, when the processed gypsum board is not in the middle position on the conveyor roller, the gypsum board will first come into contact with the guide plate during the movement. Guided by the guide plate, the gypsum board will move to the center line position of the conveyor frame, which facilitates the subsequent stacking of gypsum boards.

[0023] Optionally, it also includes a controller for automatically controlling the lifting cylinder and an infrared sensor mounted on the baffle. The controller is electrically connected to the infrared sensor and the lifting cylinder respectively. The infrared sensor can detect whether the plasterboard is against the baffle and transmit the detected signal to the controller, which then controls the movement of the lifting cylinder.

[0024] By adopting the above technical solution, it is possible to automatically detect whether the gypsum board has been moved to the correct position. When the gypsum board is detected to be in place, a signal is promptly transmitted to the controller, which then controls the lifting cylinder to start. The equipment responds faster and achieves automatic control.

[0025] In summary, this application includes at least one of the following beneficial technical effects: By using this stacking device, the need for manual stacking is avoided, reducing the workload of workers and thus improving stacking efficiency. Compared to robotic arms, the stacking device provided in this application is lower in cost and more suitable for most small and medium-sized enterprises. Compared to traditional stacking methods, it reduces the floor space required and stacks plasterboard directly above the conveyor rack, allowing the plasterboard to be stacked sequentially from bottom to top. The placement rack is designed to allow for relative adjustment of the distance between the two support rods, thus enabling the placement of plasterboard of different sizes.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a stacking device for paper-faced gypsum board.

[0032] Reference Figure 1A stacking device for paper-faced gypsum board includes a conveying component 1 installed at the discharge end of the gypsum board production equipment. The produced gypsum board is conveyed to the stacking position by the conveying component 1. A stacking mechanism 2 for stacking gypsum board is installed at the end of the conveying component 1 away from the gypsum board production equipment. After the gypsum board is produced, it is conveyed to the stacking mechanism 2 by the conveying component 1 and stacked by the stacking mechanism 2.

[0033] The conveying assembly 1 includes a conveying frame 11 set on the ground and multiple conveying rollers 12 rotatably set on the conveying frame 11. The multiple conveying rollers 12 are evenly arranged along the length of the conveying frame 11. A power source is provided on the conveying frame 11 to control the rotation of the multiple conveying rollers 12. The produced gypsum board can be conveyed to the stacking mechanism 2 through the multiple conveying rollers 12.

[0034] Reference Figure 1 and Figure 2 The stacking mechanism 2 includes a placement frame 21 installed above the conveyor frame 11 and a lifting assembly 22 installed below the conveyor frame 11. The placement frame 21 is used to stack processed gypsum boards, and the lifting assembly 22 can lift the processed gypsum boards and place them onto the placement frame 21. The conveyor frame 11 and the lifting assembly 22 are located on the upper and lower sides of the conveyor frame 11. The placement frame 21 has a rectangular frame structure and includes a pair of parallel support rods 211. The two support rods 211 are arranged along the length of the gypsum board and symmetrically arranged on both sides of the gypsum board. The two support rods 211 are connected to the conveyor frame 11. A pair of placement rods 212 are vertically fixed on each support rod 211. The two placement rods 212 are located near the ends of the support rods 211 and are parallel to each other. The gypsum boards to be stacked are placed between the two sets of placement rods 212. On each placement rod 212, near the support rod 211, there is a unidirectional rotating support block 213. The support block 213 is initially horizontal and can rotate upward to a vertical position. The support block 213 has a right-angled triangular structure, with one right-angled side attached to the placement rod 212 and the other right-angled side used to support the plasterboard. The hypotenuse of the support block 213 faces downward. When stacking the support plate 223, the edge of the plasterboard in the raised state can lift the support block 213 and cause the support block 213 to rotate until the plasterboard passes through the support block 213. After the plasterboard passes through the support block 213, the support block 213 returns to its initial state under the action of gravity, so that the four edges of the plasterboard overlap the corresponding support block 213, allowing the plasterboard to be stacked on the placement rack 21. During the stacking process, the plasterboard is stacked from bottom to top.

[0035] Furthermore, an elastic sheet 214 is fixed on the placement rod 212 and above the support block 213. One end of the elastic sheet 214 is fixed to the placement rod 212, and the other end slides against the support block 213. When the support block 213 rotates, it can compress the elastic sheet 214. After the gypsum board passes through the support block 213, the support block 213 can quickly return to its initial state under the action of the elastic sheet 214, preventing the support block 213 from failing to return to its original state after unidirectional rotation. A pair of parallel reinforcing rods 215 are fixed between the two placement rods 212 on the support rod 211. The two ends of the reinforcing rods 215 are fixed to the placement rods 212 respectively. The reinforcing rods 215 increase the connection strength between the two placement rods 212 and prevent the placement rods 212 from bending and deforming during the stacking of gypsum boards.

[0036] Reference Figure 1 and Figure 2 The lifting assembly 22 includes a lifting cylinder 221 fixed below the conveyor frame 11 and a lifting plate 222 fixed to the piston rod end of the lifting cylinder 221. The lifting plate 222 is vertically arranged and passes between two adjacent conveyor rollers 12. The upper end of the lifting plate 222 can abut against the plasterboard. The lifting cylinder 221 controls the lifting and lowering of the plasterboard, thereby stacking it on the placement frame 21. A horizontal support plate 223 is arranged between the lifting cylinder 221 and the lifting plate 222. The length direction of the support plate 223 is the same as the length direction of the plasterboard. Multiple lifting plates 222 are provided, and the multiple lifting plates 222 are evenly arranged along the length direction of the support plate 223, with the multiple lifting plates 222 evenly distributed between two conveyor rollers 11. The rollers 12 pass between each other, and the multiple lifting plates 222 are parallel to each other. Two sets of lifting cylinders 221 are provided on the lower surface of the support plate 223. The two sets of lifting cylinders 221 simultaneously lift the support plate 223 and control the multiple lifting plates 222 to rise, thereby lifting the processed gypsum board upward. The two sets of lifting cylinders 221 acting on the support plate 223 can distribute the force on the support plate 223 and simultaneously lift the multiple lifting plates 222. The multiple lifting plates 222 can distribute the force acting on the gypsum board to the corresponding lifting plates 222, avoiding the easy breakage of large gypsum boards from the lifting position when a single lifting plate 222 acts on the gypsum board.

[0037] A moving assembly 3 for controlling the relative movement of two support rods 211 is provided on the conveyor frame 11. This assembly includes a pair of fixed rods 31 spanning the conveyor frame 11, symmetrically arranged at both ends of the support rods 211. The support rods 211 are perpendicular to the fixed rods 31, and the fixed rods 31 horizontally pass through the ends of the two support rods 211, with the support rods 211 slidably engaged with the fixed rods 31. A control component for controlling the relative movement of the two support rods 211 is rotatably provided on the conveyor frame 11. This component includes a rotating screw 32 rotatably provided on the conveyor frame 11. The length direction of the rotating screw 32 is the same as the length direction of the fixed rods 31 and it is located above the fixed rods 31. The rotating screw 32 has bidirectional threads. A connecting block 33 is fixed, and the positive and negative threads on the rotating screw pass through the corresponding connecting block 33 and are threadedly engaged with the corresponding connecting block 33. A handle 34 for easy rotation is fixed at the end of the rotating screw 32. A pair of rotating screws 32 are rotatably arranged on the conveyor frame 11. The two rotating screws 32 are symmetrically arranged at both ends of the support rod 211 and above the corresponding fixed rod 31. The two rotating screws 32 are threadedly connected to both ends of the two support rods 211. A synchronous pulley 35 is fixed at the same end of the two rotating screws 32. A synchronous belt 36 is sleeved on the two synchronous pulleys 35. When one rotating screw 32 is rotated, the other rotating screw 32 rotates at the same time, so that the two support rods 211 slide more stably on the fixed rod 31.

[0038] A connecting rod 37 is inserted between two corresponding placement rods 212 on the two support rods 211. The placement rods 212 and the connecting rod 37 are slidably engaged. During the sliding process of the two support rods 211, the upper end of the placement rod 212 can slide along the connecting rod 37, thereby making the sliding process of the support rods 211 and placement rods 212 more stable and smooth, and avoiding jamming problems. When it is necessary to stack boards of different widths, the spacing between the placement rods 212 can be adjusted by rotating the screw 32, so that gypsum boards of different widths can be stacked on the placement rack 21.

[0039] Reference Figure 1 and Figure 3 A baffle 4 is fixed at the end of the conveyor frame 11 away from the production equipment. The baffle 4 is set along the width direction of the conveyor frame 11, and the lower side of the baffle 4 contacts the conveyor roller 12. When the gypsum board to be stacked comes into contact with the baffle 4, the lifting cylinder 221 is activated to lift the gypsum board. An outwardly inclined guide plate 5 is fixed at the ends of the two support rods 211 near the production equipment. The two guide plates 5 have an outward V-shaped structure. When the processed gypsum board is not in the middle position on the conveyor roller 12, the gypsum board will first come into contact with the guide plate 5 during the movement. Guided by the guide plate 5, the gypsum board moves to the center line position of the conveyor frame 11, which facilitates the subsequent stacking of gypsum boards.

[0040] Reference Figure 1 and Figure 3 The stacking device also includes a controller that enables automatic control of the stacking device. Infrared sensors 6 are fixed on the baffle 4 and located on both sides of the plasterboard. The controller is electrically connected to the lifting cylinder 221 and the infrared sensors 6. When the plasterboard abuts against the baffle 4, the infrared sensors 6 detect the position of the plasterboard and then transmit a signal to the controller, which then controls the lifting cylinder 221 to start. A height detection sensor 7 is fixed between the two placement rods 212 and located inside the upper reinforcing rod 215. The height detection sensor 7 is electrically connected to the controller. When the placement rack 21... As the stacked gypsum boards gradually increase in height and reach the position of the height detection sensor 7, the height detection sensor 7 transmits a signal to the controller, which then controls the lifting cylinder 221 to stop working until the stacked gypsum boards are completely transferred. An indicator light 8 is fixed to the upper end of the placement rod 212. The indicator light 8 is electrically connected to the controller. When the height detection sensor 7 detects that the height of the stacked boards has reached the maximum stacking quantity, the controller, receiving the signal, controls the indicator light 8 to flash, thus quickly alerting workers to the production line and allowing them to transfer the stacked boards as soon as possible. During the transfer process, the stacked boards can be transferred using a forklift. The forklift's fork arm 9 can extend under the stacked boards. During stacking, the height of the support block 213 is greater than the height of the rotating screw 32, allowing the forklift's fork arm 9 to smoothly extend under the stacked boards.

[0041] The implementation principle of the paper-faced gypsum board stacking device in this application embodiment is as follows: When stacking gypsum boards, the gypsum boards can be moved to the bottom of the conveyor frame 11, and then the gypsum boards are lifted upward by the lifting cylinder 221. During the lifting process, the edge of the gypsum board abuts against the support block 213 and rotates, so that the gypsum board passes through the support block 213. When the lifting cylinder 221 is reset, the edge of the gypsum board overlaps on multiple support blocks 213, so that the gypsum board is stacked on the placement frame 21.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
