Description

Technical Field

[0001] This invention relates to the field of gypsum board production and manufacturing, and specifically to an anti-misalignment device for stacking and conveying gypsum boards. Background Technology

[0002] After the gypsum boards pass the inspection on the production line, they need to be laminated and edge-sealed. This involves stacking two gypsum boards and transporting them to the edge-sealing machine for edge sealing. To ensure the quality of the edge sealing, the upper and lower gypsum boards must not be misaligned.

[0003] Since the upper layer of gypsum board is usually directly stacked on the lower layer of gypsum board after the boards are assembled, when the conveyor adjusts the conveying speed of the gypsum board according to the production line speed by accelerating or decelerating, the upper layer of gypsum board is prone to excessive acceleration due to acceleration or deceleration, which makes the inertia of the upper layer of gypsum board greater than the friction between it and the lower layer of gypsum board, resulting in sliding and misalignment.

[0004] Therefore, to prevent misalignment of double-layer gypsum boards during transportation, pressure rollers are typically used to increase the friction between the upper and lower layers. Specifically, an acceleration / deceleration zone is determined based on production line adjustments, and a movable pressure roller is installed above the conveyor within this zone. When the gypsum board enters the acceleration / deceleration zone, the pressure roller presses down on the upper layer to increase friction, thus preventing inertial slippage and misalignment. However, this pressure roller method has the following problems:

[0005] 1) The contact between the pressure roller and the gypsum board surface is rigid, which can easily damage the gypsum board surface or the interior of the gypsum board due to excessive pressure during the application of pressure.

[0006] 2) In the acceleration and deceleration zone, the different accelerations generated by the conveyor controlling the conveying speed will cause unequal inertial forces to be generated on the upper gypsum board, that is, the greater the acceleration, the greater the inertia.

[0007] The gypsum board production line produces gypsum boards of different specifications, and gypsum boards of different specifications have different masses. The greater the mass of the gypsum board, the greater its inertia under the same acceleration.

[0008] Therefore, when the upper gypsum board has a large inertial force due to excessive acceleration or excessive mass, the pressure roller needs to apply greater pressure to the gypsum board surface to further increase the friction. However, the contact area between the pressure roller and the gypsum board surface remains unchanged. Increasing the pressure will further increase the pressure intensity, making it easier to damage the gypsum board surface or the interior of the gypsum.

[0009] In summary, the conventional method of using pressure rollers to apply pressure to the upper layer of gypsum board to prevent misalignment is insufficient to protect the gypsum board from damage when adjusting the pressure applied to the upper layer of gypsum board according to the gypsum board specifications and production line conveying parameters. Summary of the Invention

[0056] 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.

[0057] like Figure 1 As shown, the present invention provides an anti-misalignment device for stacking and conveying gypsum boards, comprising:

[0058] Fixed frame 1 is installed across the frame of the gypsum board conveyor;

[0059] The pressure roller mechanism 2 includes a rotating wheel frame 21, multiple tubular wheel axles 22, and multiple airbag pressure rollers 23;

[0060] The rotating wheel frame 21 is slidably mounted on the fixed frame 1. Multiple tubular wheel axles 22 are symmetrically mounted on the rotating wheel frame 21 around the axis of the rotating wheel frame 21. Multiple airbag pressure rollers 23 are equidistantly mounted on the multiple tubular wheel axles 22, and the tubular wheel axles 22 are closed on one side.

[0061] The drive mechanism 3 includes a drive part and a movable part. The drive part of the drive mechanism 3 is mounted on the fixed frame 1, and the movable part of the drive mechanism 3 is connected to the wheel frame 21 through a connector to drive the wheel frame 21 to move up and down.

[0062] The air distribution mechanism 4 is coaxially mounted on the rotating wheel frame 21 and is used to pressurize or depressurize multiple tubular wheel axles 22 to increase or decrease the internal pressure of the airbag pressure wheel 23.

[0063] The air pressure adjustment mechanism 5 is installed on the fixed frame 1 and connected to the air distribution mechanism 4 through a pipeline. It is used to inflate or depress the air distribution mechanism 4 to adjust the internal pressure of the airbag pressure roller 23.

[0064] When the double-layer gypsum board is conveyed to the area directly below the pressure roller mechanism 2, the drive mechanism 3 drives the rotating wheel frame 21 to move downward, so that the tubular wheel axle 22 located directly below moves downward and presses multiple airbag pressure rollers 23 onto the upper gypsum board.

[0065] The controller can control the rotation of the rotating wheel frame 21 according to different specifications of gypsum board, so as to rotate the matching airbag pressure roller 23 to the direct under the rotating wheel frame 21;

[0066] The controller can adjust the internal pressure of the airbag pressure roller 23 by controlling the air pressure adjustment mechanism 5 through the air distribution mechanism 4 according to different specifications of gypsum board.

[0067] The protective device in this embodiment mainly utilizes the air pressure adjustment mechanism 5 to fill and release air in the tubular wheel shaft 22 according to the specifications of the gypsum board and the acceleration and deceleration values ​​of the conveyor through the air distribution mechanism 4, thereby changing the pressure inside the airbag pressure roller 23. When the airbag pressure roller 23 presses on the surface of the upper gypsum board, the airbag pressure roller 23 deforms to increase its contact area with the gypsum board surface, thereby reducing the pressure exerted by the airbag pressure roller 23, which can protect the gypsum board surface from damage.

[0068] Furthermore, the rotating wheel frame 21 of the pressure roller mechanism 2 can rotate, that is, when one of the airbag pressure rollers 23 on one of the tubular wheel axles 22 is damaged, it can rotate and replace the other tubular wheel axle 22 in time, and make the airbag pressure roller 23 on the other tubular wheel axle 22 apply pressure to the upper gypsum board.

[0069] Specifically, when one of the airbag pressure rollers 23 is damaged, its internal air pressure decreases. The air pressure adjustment mechanism 5 detects the air pressure change and will continue to inflate to maintain the air pressure. It will also rotate the wheel frame 21 to switch the tubular wheel axle 22 so that the undamaged airbag pressure roller 23 faces downward.

[0070] The drive mechanism 3 is mainly used to drive the rotating wheel frame 21 to move up and down. When the double-layer gypsum board moves to the acceleration and deceleration zone, the rotating wheel frame 21 moves down, so that the airbag pressure roller 23 presses on the upper layer of gypsum board. After the gypsum board passes through the acceleration and deceleration zone, the rotating wheel frame 21 moves up to facilitate pressure protection for the gypsum board being transported later.

[0071] Compared to the existing method of applying pressure with pressure rollers, this embodiment uses an adjustable airbag pressure roller 23 to apply pressure to the upper gypsum board. This allows for different accelerations to be generated according to different gypsum board specifications and different gypsum board acceleration and deceleration, and the pressure inside the airbag pressure roller 23 can be adjusted in advance. This can prevent the upper gypsum board from being misaligned and also avoid damage to the gypsum board surface.

[0072] The airbag pressure roller 23 deforms during the pressure process to increase the contact area, thereby reducing the pressure of the airbag pressure roller 23 and protecting the gypsum board surface. Since the pressure inside the airbag pressure roller 23 needs to be adjustable depending on different specifications or accelerations, the following preferred embodiment is provided.

[0073] like Figure 3 As shown, the airbag pressure roller 23 includes a wheel rim 231 and an airbag ring 232. Two air holes 233 are symmetrically arranged through the wheel rim 231. An air intake valve pipe 234 and an air exhaust valve pipe 235 are respectively arranged on the inner side wall of the airbag ring 232.

[0074] When the airbag ring 232 is installed on the wheel rim 231, the intake valve pipe 234 and the exhaust valve pipe 235 are respectively sealed and inserted into the two air holes 233;

[0075] Among them, multiple symmetrical holes are preset on the tubular wheel axle 22, the air hole 233 is aligned with the preset holes on the tubular wheel axle 22, and the wheel rim 231 is sealed and assembled with the tubular wheel axle 22.

[0076] Specifically, the airbag ring 232 is inflated through the intake valve pipe 234 and deflated through the exhaust valve pipe 235, while the intake valve pipe 234 and the exhaust valve pipe 235 are one-way valves with different conduction directions.

[0077] The intake valve pipe 234 and the exhaust valve pipe 235 are connected to the inside of the tubular wheel axle 22 through the air hole 233 and the preset hole on the tubular wheel axle 22. Therefore, the airbag ring 232 can be inflated and deflated when a pressure difference is generated with the inside of the tubular wheel axle 22.

[0078] Specifically, when the internal pressure of the tubular wheel axle 22 is greater than the internal pressure of the airbag ring 232, the intake valve pipe 234 opens and the exhaust valve pipe 235 closes, and the gas in the tubular wheel axle 22 inflates into the airbag ring 232.

[0079] When the internal pressure of the tubular wheel axle 22 is less than the internal pressure of the airbag ring 232, the exhaust valve pipe 235 opens and the intake valve pipe 234 closes, and the gas in the airbag ring 232 is discharged into the tubular wheel axle 22.

[0080] When the internal pressure of the tubular wheel axle 22 is equal to the internal pressure of the airbag ring 232, and both the intake valve pipe 234 and the exhaust valve pipe 235 are closed, the airbag ring 232 remains in place.

[0081] Since the tubular wheel axle 22 is connected to the air hole 233 by a preset hole position, when the wheel rim 231 is assembled with the tubular wheel axle 22, the hole position and the air hole 233 need to be accurately aligned, which increases the assembly difficulty and makes it easy for air leakage or blockage of the hole to cause slow inflation and deflation.

[0082] Therefore, further, such as Figure 3 As shown, multiple air inlet valves 221 and multiple air outlet valves 222 are provided at multiple preset holes on the tubular wheel axle 22, and the multiple air inlet valves 221 and multiple air outlet valves 222 are arranged symmetrically.

[0083] When the wheel rim 231 is installed on the tubular wheel axle 22, the inflation valve pipe 221 and the suction valve pipe 222 are respectively sealed and inserted into two air holes 233, and the inflation valve pipe 221 and the intake valve pipe 234 are located in the same air hole 233, and the suction valve pipe 222 and the exhaust valve pipe 235 are located in the same air hole 233.

[0084] Among them, the wheel rim 231 is composed of two half-circle structures joined together.

[0085] Specifically, an inflation valve pipe 221 and an exhaust valve pipe 222 are provided on the hole of the tubular wheel axle 22, and the wheel rim 231 is an assembled structure. Therefore, when assembling the wheel rim 231, it is only necessary to fit the air hole 233 of the wheel rim 231 into the corresponding inflation valve pipe 221 and exhaust valve pipe 222. The installation is convenient and there will be no situation of poor sealing, leakage or blockage due to misalignment.

[0086] When the inflation valve tube 221, the suction valve tube 222, the intake valve tube 234, and the exhaust valve tube 235 are all inserted into the air hole 233, the air hole 233 is used to connect the inflation valve tube 221 and the intake valve tube 234, as well as the suction valve tube 222 and the exhaust valve tube 235. Therefore, it is necessary to improve the sealing performance between the inflation valve tube 221, the suction valve tube 222, the intake valve tube 234, and the exhaust valve tube 235 and the inner wall of the air hole 233 to prevent air leakage.

[0087] Therefore, further, such as Figure 3 As shown, multiple sealing rings 24 are coaxially installed on the outer walls of the inflation valve pipe 221, the suction valve pipe 222, the intake valve pipe 234, and the exhaust valve pipe 235 through pre-set annular grooves on their outer walls.

[0088] The diameter of the middle section of pore 233 is smaller than the diameter of its two ends, and the two ends of pore 233 smoothly transition to the middle section;

[0089] When the wheel rim 231 is installed on the tubular wheel axle 22 and the airbag ring 232 is installed on the wheel rim 231, the inflation valve pipe 221, the suction valve pipe 222, the intake valve pipe 234 and the exhaust valve pipe 235 press the sealing ring 24 against the inner wall of the air hole 233.

[0090] The diameters of the inflation valve pipe 221, the extraction valve pipe 222, the intake valve pipe 234, and the exhaust valve pipe 235 are less than or equal to the diameter of the middle section of the air hole 233.

[0091] Specifically, the inflation valve pipe 221, the suction valve pipe 222, the intake valve pipe 234, and the exhaust valve pipe 235 are sealed to the inner wall of the air hole 233 by a sealing ring 24. The outer diameter of the sealing ring 24 should be larger than the inner diameter of the air hole 233 so that the sealing ring 24 is pressed tightly inside the air hole 233.

[0092] As the diameter of the vent 233 decreases from both ends toward the middle, when the inflation valve tube 221, the extraction valve tube 222, the intake valve tube 234, and the exhaust valve tube 235 are inserted into the vent 233, the sealing ring 24 closer to the middle of the vent 233 is squeezed tighter, thereby improving the sealing effect.

[0093] Furthermore, the air hole 233 adopts a variable diameter port, which makes it easy to insert the air inlet valve pipe 221, the air outlet valve pipe 222, the air inlet valve pipe 234 and the air outlet valve pipe 235 into the air hole 233, thereby improving the ease of assembly.

[0094] During the process of airbag ring 232 being deformed under pressure, the side closer to wheel rim 231 is prone to deformation and contact with the edge of wheel rim 231. Since the contact area between the edge of wheel rim 231 and airbag ring 232 is small, a large pressure is generated between the two, and the frictional force generated by the axial compression deformation between the two is large, which can easily damage airbag ring 232.

[0095] Therefore, as Figure 3 As shown, the wheel rim 231 has an annular airbag seat 236, and the annular airbag seat 236 smoothly transitions to the outer wall of the wheel rim 231;

[0096] The axial lengths of the annular airbag seats 236 on each tubular wheel axle 22 may be the same or different.

[0097] Specifically, the smooth transition between the annular airbag seat 236 and the outer wall of the wheel rim 231 ensures a smoother contact when the airbag ring 232 comes into contact with the outer wall of the wheel rim 231 and the annular airbag seat 236 after the airbag ring 232 is deformed under pressure. This reduces friction and increases the contact area to reduce pressure, thereby preventing the airbag ring 232 from being damaged by pressure.

[0098] The air distribution mechanism 4 connects to the air pressure adjustment mechanism 5 and multiple tubular wheel axles 22, thereby enabling the air pressure adjustment mechanism 5 to adjust the pressure of the multiple airbag pressure rollers 23. However, the rotating wheel frame 21 can rotate, while the air distribution mechanism 4 is connected to the air pressure adjustment mechanism 5 via piping, and the piping of the air pressure adjustment mechanism 5 is fixed. Therefore, in order to keep the tubular wheel axles 22 connected to the air pressure adjustment mechanism 5 during rotation with the rotating wheel frame 21, the following preferred embodiment is provided.

[0099] like Figure 1 and Figure 2 As shown, the gas distribution mechanism 4 includes a main gas tank 41, multiple gas distribution tanks 42, and multiple gas transmission pipes 43;

[0100] The main gas tank 41 is coaxially mounted on the rotating wheel frame 21, and multiple gas distribution tanks 42 are symmetrically mounted on the rotating wheel frame 21 and are coaxial with multiple tubular wheel shafts 22 respectively. The main gas tank 41 and the gas distribution tanks 42 are connected by gas transmission pipes 43.

[0101] Specifically, the main gas tank 41 can supply pressure to multiple gas distribution tanks 42 through multiple gas supply pipes 43, or the multiple gas distribution tanks 42 can depressurize the main gas tank 41 through multiple gas supply pipes 43.

[0102] Furthermore, when the airbag pressure roller 23 located directly below is compressed, its internal air pressure increases. This increased air pressure can then be evenly distributed to the remaining airbag pressure rollers 23 through the air distribution tank 42, air supply pipe 43, and main air tank 41. This reduces the deformation of the airbag ring 232 on the non-compressed side during operation, thus preventing the airbag ring 232 from over-expanding and affecting its service life.

[0103] The main air tank 41 is coaxially mounted with the rotating wheel frame 21, which allows the air pressure adjustment mechanism 5 to be easily connected to the end of the main air tank 41 during rotation, so that the rotation of the main air tank 41 does not affect the pipeline connection.

[0104] Similarly, since the gas distributor 42 and the tubular wheel shaft 22 are arranged coaxially, the rotation of the tubular wheel shaft 22 does not affect the operation of the gas distributor 42.

[0105] The air pressure adjustment mechanism 5 needs to be able to inflate the tubular wheel axle 22 and expel the gas inside the airbag pressure wheel 23. Therefore, the following preferred embodiment is provided.

[0106] like Figure 1 and Figure 2 As shown, the air pressure adjustment mechanism 5 includes an air compressor 51, an air pipeline 52, and an exhaust valve 53;

[0107] The air compressor 51 is mounted on the fixed frame 1, one end of the air pipe 52 is mounted on the air compressor 51, and the other end of the air pipe 52 is coaxially rotatably mounted on the main air tank 41. The exhaust valve 53 is mounted on the air pipe 52.

[0108] Specifically, the air compressor 51 can supply air to the main air tank 41 through the air pipeline 52, and the exhaust valve 53 can control the main air tank 41 to exhaust air to the outside. The exhaust valve 53 is a solenoid valve.

[0109] The drive mechanism 3 is used to drive the rotating wheel frame 21 to move up and down to achieve intermittent motion and to apply pressure to the upper gypsum board conveyed to the acceleration and deceleration zone, as detailed below:

[0110] like Figure 1 As shown, the driving part and the movable part of the drive mechanism 3 are two linear actuators 31 and two push blocks 32 symmetrically arranged on the fixed frame 1, respectively. The push blocks 32 are mounted on the linear actuators 31 so that the push blocks 32 move up and down when the linear actuators 31 are working.

[0111] Short shaft tubes 25 are provided at both ends of the rotating wheel frame 21, and assembly blocks 26 are rotatably fitted at the ends of the short shaft tubes 25. The assembly blocks 26 are installed on the push blocks 32 on the corresponding sides, and a reversing motor 27 is provided on the outer wall of one of the assembly blocks 26. The shaft of the reversing motor 27 is connected and installed to the short shaft tube 25.

[0112] Among them, the air distribution mechanism 4 and the reversing motor 27 are located on both sides of the rotating wheel frame 21.

[0113] Specifically, the linear driver 31 can be a linear motor or other linearly driven device. The linear driver 31 can drive the push block 32 to move up and down, thereby enabling the assembly block 26 to drive the short shaft tube 25 to move up and down, which in turn enables the rotating wheel frame 21 to move up and down.

[0114] The short shaft tube 25 is rotatably mounted on the assembly block 26, so the rotation of the rotating wheel frame 21 does not affect the up-and-down movement of the assembly block 26.

[0115] Furthermore, since the reversing motor 27 and the air distribution mechanism 4 are not located on the same side, the reversing motor 27 controls the rotation of the rotating wheel frame 21, and the air distribution mechanism 4 controls the pressure inside the tubular wheel axle 22 and the airbag pressure wheel 23 without affecting each other.

[0116] The gas distribution mechanism 4 needs to rotate synchronously with the rotating wheel frame 21, and the main gas tank 41 needs to maintain its connection with the gas pipeline 52. The gas distribution tank 42 needs to be fixed and not affect the rotation of the tubular wheel shaft 22. Therefore, the following preferred embodiments are provided.

[0117] like Figure 1 and Figure 2 As shown, the main gas tank 41 is located inside the short shaft tube 25, and multiple gas delivery pipes 43 pass through the short shaft tube 25 and are connected to multiple gas distribution tanks 42.

[0118] The rotating wheel frame 21 includes a main frame 211, and multiple sub-frames 212 are symmetrically arranged on the main frame 211. The main frame 211 and the sub-frames 212 are connected by a quick-release and quick-install structure.

[0119] A shaft seat 223 is fitted to the open end of the tubular wheel shaft 22, and a shaft hole of the shaft seat 223 is provided through it. The open end of the gas distribution tank 42 is detachably installed in the shaft hole of the shaft seat 223.

[0120] Specifically, the main gas tank 41 rotates synchronously with the rotating wheel frame 21. Therefore, the main gas tank 41 needs to be set coaxially with the rotating wheel frame 21. It is set inside the short shaft tube 25, which does not affect the operation of the rotating wheel frame 21.

[0121] The rotating wheel frame 21 adopts a quick-release and quick-install structure, that is, the short shaft tube 25 is installed at both ends of the main frame 211, while multiple auxiliary frames 212 are installed on the side wall of the main frame 211 and distributed at equal intervals. When the airbag pressure roller 23 is being repaired or replaced, the auxiliary frame 212 can be quickly removed from the main frame 211 through the quick-release and quick-install structure, so that the repair and replacement process does not affect the misalignment protection of the gypsum board being conveyed on the conveyor.

[0122] One end of the tubular wheel axle 22 is fixedly connected to the sub-frame 212 via the axle seat 223, so the gas distribution tank 42 can be inserted into the axle seat 223 and connected to the tubular wheel axle 22. Thus, the rotation of the tubular wheel axle 22 does not affect the gas distribution tank 42.

[0123] Furthermore, when disassembling the subframe 212, the air distribution tank 42 can be pulled out of the bearing seat 223. The air supply pipe 43 is a flexible hose, and each air supply pipe 43 is connected to the air distribution tank 42 as a quick-connect fitting. Thus, after the air supply pipe 43 is pulled out, the air supply pipe 43 stops venting outward, preventing air pressure leakage.

[0124] When disassembling the tubular wheel axle 22, the sub-frame 212 is removed simultaneously, and the sub-frame 212 is connected to the tubular wheel axle 22. When replacing the airbag ring 232, the sub-frame 212 needs to be removed, and then the damaged airbag ring 232 is removed from one end of the tubular wheel axle 22. The new airbag ring 232 is then fitted from one end of the tubular wheel axle 22 onto the corresponding wheel rim 231. During the process of removing and installing the airbag ring 232, it is necessary to frequently stretch and pass through the undamaged airbag pressure rollers 23 along the way, which increases the difficulty of installation.

[0125] Therefore, further, such as Figure 3 As shown, the tubular wheel shaft 22 is composed of multiple tubular shafts 224 connected coaxially and sealed by connectors, and the multiple tubular shafts 224 can be detached and assembled.

[0126] Each airbag pressure roller 23 is mounted on a corresponding tube shaft 224.

[0127] Specifically, the tubular wheel shaft 22 is composed of multiple sections, so if one of the airbag pressure rollers 23 is damaged, it can be quickly removed and replaced with a new airbag pressure roller 23. The difficulty of disassembly and assembly is reduced, and the speed of maintenance can be further improved without affecting the production efficiency of the production line.

[0128] 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.
