Description

Technical Field

[0001] This invention relates to the field of gypsum board cutting technology, specifically to a single-sided step-by-step alignment device for gypsum board sheets. Background Technology

[0002] In the later stages of production line processing, gypsum boards need to be cut. In order to protect the paper surface of the boards, two gypsum boards are combined into a pair of boards by a laminating machine during the gypsum board production process and then cut. However, during the laminating process, the two boards may not be completely aligned, and there may be positional differences between the two boards in front, back, left, and right. Therefore, the two boards need to be aligned before cutting to ensure the cutting quality.

[0003] The alignment process of the sheet metal includes two processes: left-right alignment and front-back alignment. The sheet metal is placed on a conveyor belt and transported to the alignment work area for alignment in the front-back and left-back directions. Most existing alignment devices use rollers for left-back alignment and pushers for front-back alignment.

[0004] Most existing front-to-back alignment operations use cylinders for alignment, which has the following drawbacks:

[0005] (1) The front and back directions of the board are the wedge-shaped edge of the gypsum board. During the gypsum board forming stage, the gypsum is not easy to fill the wedge-shaped edge. Therefore, there is a hollow part between the two layers of facing paper. If there is a hollow part on the front and back sides of the board, if the cylinder is used to align them, the gypsum board side may be crushed or damaged due to compression during the alignment process.

[0006] (2) When using the cylinder to push and align, the material needs to be stopped from being transported and kept still. The material is then aligned by the cylinder pressing in the front and back directions, which affects work efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a single-sided step-by-step alignment device for gypsum board, so as to solve the technical problem in the prior art that when there are hollow parts on the front and rear sides, the method of aligning with cylinders is prone to causing indentations or damage to the edges due to compression.

[0008] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0009] A single-sided step-by-step alignment device for gypsum board includes:

[0010] The roller conveyor section includes multiple parallel roller groups that drive the conveying of gypsum board to gypsum board through the rotation of the roller groups;

[0011] The front stop assembly can apply force to the side of the plasterboard pair to align the upper and lower panels of the plasterboard pair.

[0012] The rear stop assembly is capable of moving up and down and serves as a positioning reference to abut against the side of the plasterboard pair in the moving state so that the upper and lower plates of the plasterboard pair are aligned.

[0013] The roller assembly drives the plasterboard pair through friction transmission with the plasterboard pair, causing the plasterboard pair to pass sequentially through the front stop assembly and the rear stop assembly. The front stop assembly and the rear stop assembly sequentially perform online alignment adjustment on the two sides of the plasterboard pair in the moving state, and the roller assembly can rotate freely when the rear stop assembly simultaneously contacts the two plasterboard pairs.

[0014] As a preferred embodiment of the present invention, a detection component is provided at the installation position of the front stop assembly. The detection component is used to monitor the conveying position of the gypsum board pair. The front stop assembly starts working when the detection component detects the tail of the gypsum board pair to align the gypsum board pair in line.

[0015] As a preferred embodiment of the present invention, the front stop assembly includes at least one first telescopic cylinder disposed below the roller assembly, and a push plate unit movably mounted between two adjacent roller assemblies, wherein the two adjacent push plate units are connected by an association component, and the push plate unit and the association component form a comb tooth structure.

[0016] The telescopic shaft of the first telescopic cylinder is connected to the end of the push plate unit. The telescopic shaft of the first telescopic cylinder moves linearly in a direction parallel to the conveying direction of the gypsum board. The first telescopic cylinder drives the push plate unit to swing around the mounting point of the first telescopic cylinder so that the push plate unit pushes the side of the gypsum board to align.

[0017] As a preferred embodiment of the present invention, the push plate unit includes a swing rod movably mounted between two adjacent roller groups, and a retaining plate movably connected to the swing rod, wherein the retaining plate is provided with an alignment push plate inside;

[0018] The telescopic shaft of the first telescopic cylinder is movably connected to the bottom of the sleeve plate via an L-shaped mounting plate. When the first telescopic cylinder is working, it drives the alignment push plate to rotate around the mounting position of the sleeve plate and the telescopic shaft.

[0019] As a preferred embodiment of the present invention, the rotation angle of the alignment pusher is 0° to 90°, the pushing surface of the alignment pusher when rotated to 0° is lower than the roller group, and the pushing surface of the alignment pusher when rotated to 90° is higher than the stacking thickness of the gypsum board.

[0020] In a preferred embodiment of the present invention, the associated component includes a horizontal link disposed between the two sleeve plates, and all the alignment push plates rotate synchronously through the horizontal link.

[0021] In a preferred embodiment of the present invention, the sleeve plate is engaged between the two side surfaces of the alignment push plate, and the surface of the alignment push plate facing the gypsum board forms a pushing gap with the installation position of the sleeve plate.

[0022] In a preferred embodiment of the present invention, the detection component is installed at the connection position between the swing rod and the sleeve plate. The detection component is connected to a control unit. The output end of the control unit is connected to the drive component of the first telescopic cylinder and the rear stop component. When the detection component detects the tail of the plasterboard, the control unit controls the first telescopic cylinder to pull the alignment push plate to rotate to a vertical state, and controls the drive component of the rear stop component to lift up as a positioning reference.

[0023] In a preferred embodiment of the present invention, the sleeve plate is disposed on the side of the alignment push plate, and the pushing distance between the sleeve plate and the alignment push plate is not less than the maximum misalignment distance between the upper and lower plates of the gypsum board.

[0024] When the first telescopic cylinder drives the alignment push plate to rotate to 90°, it can contact the lower side of the plasterboard pair, so as to push the upper part of the two plasterboard pairs to move to align with the lower plate.

[0025] As a preferred embodiment of the present invention, the rear stop assembly includes at least one second telescopic cylinder disposed below the roller assembly, and a support horizontal plate mounted on the second telescopic cylinder. The support horizontal plate is equipped with a plurality of evenly distributed abutment vertical plates, each of the abutment vertical plates being located between two adjacent roller assemblies. The abutment vertical plates are capable of pushing the upper plate of the gypsum board to move so that the upper plate is aligned with the lower plate.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] This invention performs a step-by-step alignment operation on one side of the assembled gypsum board in the front-to-back direction. First, the front stop is used to push the board for alignment on one side, and then the rear stop is used to push the board for alignment on the other side. After the upper and lower gypsum boards are aligned, the rollers that transport the gypsum boards idle to reduce the stress on the sides of the gypsum boards and effectively avoid indentations or damage to the sides of the gypsum boards due to squeezing.

[0028] In addition, this embodiment enables online conveying and alignment of gypsum boards without stopping the roller assembly. The alignment of the gypsum boards in the front and back directions is completed during the conveying process, thereby improving the efficiency of the alignment operation.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 As shown, the present invention provides a single-sided step-by-step alignment device for gypsum board. In this embodiment, the gypsum board after lamination is aligned in a single-sided step-by-step manner in the front and back directions. First, the front stop is used to push the board for single-sided alignment, and then the rear stop is used to push the board for alignment on the other side. After the upper and lower gypsum board are aligned, the rollers that transport the gypsum board are idled to reduce the force on the side of the gypsum board and effectively avoid the situation of indentation or damage to the side of the gypsum board due to squeezing.

[0042] In addition, this embodiment enables online conveying and alignment of gypsum boards without stopping the roller assembly. The alignment of the gypsum boards in the front and back directions is completed during the conveying process, thereby improving the efficiency of the alignment operation.

[0043] Specifically, it includes:

[0044] The roller conveyor section includes multiple parallel roller groups 1, which are driven by the rotation of the roller groups 1 to convey gypsum board to board.

[0045] The front stop assembly 2 can apply force to the side of the gypsum board pair to align the upper and lower panels of the gypsum board pair.

[0046] The rear stop assembly 3 can move up and down and serve as a positioning reference to stop the other side of the plasterboard pair in the moving state so that the upper and lower plates of the plasterboard pair are aligned.

[0047] Among them, the roller assembly 1 drives the gypsum board pair through friction transmission with the gypsum board pair to pass through the front stop assembly 2 and the rear stop assembly 3 in sequence. The front stop assembly 2 and the rear stop assembly 3 sequentially perform online alignment adjustment on the two sides of the moving gypsum board pair. The roller assembly 1 can rotate freely when the rear stop assembly 3 contacts the two gypsum board pairs at the same time, so as to avoid damage to the sides of the gypsum board pair after alignment.

[0048] The installation position of the front stop assembly 2 is provided with a detection component 4. The detection component 4 is used to monitor the conveying position of the gypsum board pair. The front stop assembly 2 starts to work when the detection component 4 detects the tail of the gypsum board pair to align the gypsum board pair in line.

[0049] Under normal transport conditions, both the front stop assembly 2 and the rear stop assembly 3 are located below the roller conveyor section, thus enabling the roller conveyor section to perform its normal transport function.

[0050] When the gypsum board passes the front stop assembly 2, the front stop assembly 2 immediately works, applying force to the side of the gypsum board pair. This is mainly for cases where the upper and lower boards are misaligned, and the upper board is close to the front stop assembly 2, i.e., the upper board is in front and the lower board is in back. At this time, the front stop assembly 2 pushes the upper board to move backward and align with the lower board. At the same time, the roller assembly 1 continues to work, conveying the gypsum board pair together to the rear stop assembly 3. When the gypsum board pair contacts the aligned gypsum board pair, the roller assembly 1 slips, which can prevent damage to the sides of the board in the front and back directions.

[0051] When the upper plate is positioned rearward and the lower plate is positioned forward, the front stop assembly 2 pushes the lower plate first. Due to the weight of the upper plate, the lower plate accelerates on the roller assembly 1 under the pushing action of the front stop assembly 2, thus failing to smoothly achieve the misalignment of the upper and lower plates. At this time, the roller assembly 1 simultaneously transports the upper and lower plates to the rear stop assembly 3. When the upper plate contacts the rear stop assembly 3, the lower plate has not yet contacted the rear stop assembly 3. Therefore, the lower plate continues to move towards the rear stop assembly 3 under the transport of the roller assembly 1, while the upper plate moves in the opposite direction to the lower plate under the blocking action of the rear stop assembly 3. In this way, the upper and lower plates are aligned.

[0052] Therefore, this embodiment effectively ensures the front and rear alignment of the gypsum boards by combining the front and rear stops, and completes the alignment work during the movement of the gypsum boards, improving work efficiency without interrupting the conveying process. In addition, the gypsum boards are aligned on one side to avoid squeezing the gypsum boards in the front and rear directions, thereby effectively preventing side damage to the gypsum boards.

[0053] In addition, this embodiment provides a preferred embodiment for the front stop assembly 2, such as... Figure 2 and Figure 3 As shown, the front stop assembly 2 includes at least one first telescopic cylinder 23 disposed below the roller assembly 1, and a push plate unit 21 movably mounted between two adjacent roller assemblies 1. The two adjacent push plate units 21 are connected by an association component 22, and the push plate unit 21 and the association component 22 form a comb structure.

[0054] The telescopic shaft of the first telescopic cylinder 23 is connected to the end of the push plate unit 21. The telescopic shaft of the first telescopic cylinder 23 moves linearly in a direction parallel to the gypsum board conveying direction. The first telescopic cylinder 23 drives the push plate unit 21 to swing around the mounting point of the first telescopic cylinder 23 so that the push plate unit 21 pushes the gypsum board to align the sides of the board.

[0055] The push plate unit 21 includes a swing rod 211 movably mounted between two adjacent roller groups 1, and a retaining plate 212 movably connected to the swing rod 211. The retaining plate 212 has an alignment push plate 213 inside.

[0056] The telescopic shaft of the first telescopic cylinder 23 is movably connected to the bottom of the sleeve plate 212 via the L-shaped mounting plate 214. When the first telescopic cylinder 23 is working, it drives the alignment push plate 213 to rotate around the mounting position of the sleeve plate 212 and the telescopic shaft.

[0057] The rotation angle of the alignment push plate 213 is 0° to 90°. When the alignment push plate 213 rotates to 0°, the pushing surface is lower than the roller group 1, and when the alignment push plate 213 rotates to 90°, the pushing surface is higher than the stacking thickness of the gypsum board.

[0058] When the first telescopic cylinder 23 extends outward, the telescopic shaft of the first telescopic cylinder 23 pushes the sleeve plate 212 and the alignment push plate 213 to rotate through the L-shaped mounting plate 214 until they rotate to 0°. At this time, the alignment push plate 213 and the swing rod 211 are both below the roller group 1, so the gypsum board is conveyed normally along the surface of the roller group 1.

[0059] When the first telescopic cylinder 23 retracts inward, the telescopic shaft of the first telescopic cylinder 23 pushes the sleeve plate 212 and the alignment push plate 213 to rotate through the L-shaped mounting plate 214 until they rotate to 90°. At this time, one surface of the alignment push plate 213 faces the plasterboard pair, pushing the plasterboard pair with the upper plate forward and the lower plate backward to align them. Meanwhile, the swing rod 211 is on the other surface of the alignment push plate 213 and will not damage the side of the plasterboard pair, thus completing the alignment work.

[0060] To reduce the use of the first telescopic cylinder 23, the associated component 22 in this embodiment includes a horizontal link disposed between the two sleeve plates 212, and all the alignment push plates 213 rotate synchronously via the horizontal link.

[0061] In this embodiment, the alignment push plate 213 is connected by a horizontal connecting rod, thus greatly reducing the number of first telescopic cylinders 23 used. When one alignment push plate 213 is pushed by the first telescopic cylinder 23 to make a swinging motion, the other alignment push plates 213 swing synchronously under the drive of the horizontal connecting rod.

[0062] To further explain the operation of the front stop assembly 2 and the rear stop assembly 3, the detection assembly 4 is installed at the connection position between the swing arm 211 and the sleeve plate 212. The detection assembly 4 is connected to a control unit, and the output end of the control unit is connected to the drive component of the first telescopic cylinder 23 and the rear stop assembly 3.

[0063] One end of the swing rod 211 is movably mounted on the side surface of the bearing frame of the roller assembly 1, and the other end of the swing rod 211 is movably mounted on the sleeve plate 212. Therefore, the detection component 4 is specifically installed at the connection point between the aligning push plate 213 and the swing rod 211 when the aligning push plate 213 is in a horizontal state.

[0064] The detection component 4 specifically uses a laser detector. When the output signal of the laser detector indicates that the head of the plasterboard has been detected, the control unit keeps the alignment push plate 213 in a horizontal state, and the rear stop component 3 remains below the roller group 1.

[0065] When the laser detector outputs a signal indicating that the tail of the gypsum board is detected, the control unit controls the first telescopic cylinder 23 to pull the alignment push plate 213 to rotate to a vertical position, and controls the drive component of the rear stop assembly 3 to lift up as a positioning reference. During the process of the alignment push plate 213 rotating to a vertical position, it pushes the upper plate in front to align.

[0066] It should be further explained that when the alignment push plate 213 rotates to the vertical position, the distance between it and the rear stop assembly 3 is greater than the width of the plasterboard in the front-to-back direction. Therefore, the plasterboard first undergoes the alignment operation of the alignment push plate 213. When the upper board is in front and the lower board is in back, the alignment push plate 213 pushes the upper board to move until the upper and lower boards are aligned. When the upper board is in back and the lower board is in front, the alignment push plate 213 pushes the lower board to move. However, under the gravity of the upper board, the lower board may not be able to align with the upper board. Therefore, the rear stop assembly 3 is still needed to perform further alignment. When the upper and lower boards are in the original aligned state, the alignment push plate 213 pushes the upper and lower boards to move simultaneously for a short time, and they are still in the aligned state.

[0067] The sleeve plate 212 is engaged between the two side surfaces of the alignment push plate 213, and the surface of the alignment push plate 213 facing the gypsum board pair forms a pushing gap with the installation position of the sleeve plate 212. That is, the sleeve plate 212 is set on the side of the alignment push plate 213, and the pushing gap between the sleeve plate 212 and the alignment push plate 213 is not less than the maximum misalignment distance between the upper and lower plates of the gypsum board pair.

[0068] Therefore, when the first telescopic cylinder 23 drives the alignment push plate 213 to rotate to 90°, it can contact the lower side of the gypsum board pair, so as to push the upper plate of the two gypsum board pairs to move to align with the lower plate.

[0069] As a preferred implementation method, such as Figure 4 and Figure 5As shown, the rear stop assembly 3 includes at least one second telescopic cylinder 31 disposed below the roller assembly 1, and a support horizontal plate 32 mounted on the second telescopic cylinder 31. Multiple evenly distributed abutment vertical plates 33 are mounted on the support horizontal plate 32. Each abutment vertical plate 33 is located between two adjacent roller assemblies 1. The abutment vertical plate 33 can push the upper plate of the gypsum board to move so that the upper plate is aligned with the lower plate.

[0070] When the detection component 4 detects the tail of the gypsum board pair, the first telescopic cylinder 23 and the second telescopic cylinder 31 work simultaneously. The first telescopic cylinder 23 drives the extrusion push plate 213 to push the tail of the gypsum board pair. Then, under the drive of the roller group 1, the gypsum board pair continues to move to the blocking vertical plate 33. The blocking vertical plate 33 further pushes the gypsum board pair to align up and down.

[0071] It should also be noted that when the alignment push plate 213 rotates to 90°, the first telescopic cylinder 23 drives the alignment push plate 213 to rotate in the opposite direction to 0°. When the blocking vertical plate 33 contacts the bottom plate of the gypsum board, the roller group 1 slips and spins freely, which can reduce the side force of the gypsum board on the board. Then the second telescopic cylinder 23 drives the blocking vertical plate 33 to move down to the bottom of the roller group 1 to perform the alignment operation on the next gypsum board.

[0072] Therefore, this embodiment performs a step-by-step, single-sided alignment operation on misaligned gypsum boards, which can effectively reduce the risk of lateral squeezing damage during the alignment process and enables online alignment, thus improving work efficiency.

[0073] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
