[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 As shown, the present invention provides a gypsum board stacking device and method with a size verification function, wherein the device is equipped with a pre-adjusting feeding structure 1, a classified material transportation structure 2, an adaptive stacking structure 3, and an image acquisition and processing module 4.

[0052] The pre-adjustment feeding structure 1 is arranged at the discharge end of the gypsum board production line, and is used to feed the gypsum board and to offset and adjust the position of the gypsum board on the pre-adjustment feeding structure 1.

[0053] The classification and transportation structure 2 is arranged at the discharge end of the pre-adjustment feeding structure 1. There are at least two classification and transportation structures 2, and the classification and transportation structures 2 are arranged in sequence. The classification and transportation structure 2 is used to receive the gypsum board transported by the pre-adjustment feeding structure 1 and transport the gypsum board.

[0054] The adaptive stacking structure 3 is correspondingly arranged on the side of the classification and transportation structure 2. The classification and transportation structure 2 transports the gypsum boards of corresponding sizes to the corresponding side of the adaptive stacking structure 3. When the gypsum boards of corresponding sizes arrive, the adaptive stacking structure 3 positions and lifts the corresponding gypsum boards so as to stack them with the next gypsum boards of corresponding sizes arriving at the side of the adaptive stacking structure 3. A limited space 5 is formed inside the adaptive stacking structure 3 for the gypsum boards to enter.

[0055] The image acquisition and processing module 4 is arranged on the pre-adjustment feeding structure 1, and the image acquisition and processing module 4 is used to acquire the image of the gypsum board to calculate the offset data and size of the gypsum board. The pre-adjustment feeding structure 1 performs offset adjustment on the gypsum board according to the offset data of the gypsum board, and the classification and transportation structure 2 transports the gypsum board to the corresponding adaptive stacking structure 3 according to the size of the gypsum board.

[0056] Among them, the image acquisition and processing module 4 verifies the size data of the gypsum board based on the distance between the limit space 5 and the gypsum board, and sends a stacking prevention signal to the adaptive stacking structure 3 when the gypsum board size data is abnormal, and the adaptive stacking structure 3 resets based on the stacking prevention signal.

[0057] In the present invention, since there is only one transport line, which is composed of multiple classified material transport structures 2, each gypsum board needs to be set to the same transport speed and transport state so as not to affect the stacking process of adjacent gypsum boards, so that the pre-adjusted loading structure 1 and the classified material transport structure 2 transport the gypsum boards at equal intervals. Assume that the previous gypsum board arrives at the second adaptive stacking structure 3 for stacking, at this time the corresponding classified material transport structure 2 is in a stopped state, and the next gypsum board is at the first adaptive stacking structure 3, wherein the stacking process includes the lifting process of the gypsum board and the stacking process with another gypsum board. In the above case, both gypsum boards are in the stacking process, and the two classified material transport structures 2 need to be set to the same transport speed, started and closed at the same time. In addition, in order to cooperate with the conveying speed of the classified material transport structure 2, the pre-adjusted loading structure 1 is also set to the same transport speed.

[0058] The present invention provides an adaptive stacking structure 3, which has a limited space 5 formed inside for gypsum boards to enter. Before stacking the gypsum boards, the size of the gypsum boards can be verified by detecting the distance between the limited space 5 and the gypsum boards. Gypsum boards with larger sizes cannot enter the limited space 5. For gypsum boards with smaller sizes, their stacking process is directly prevented according to abnormal size verification results. A verification process is added on the basis of the original image acquisition and recognition, thereby improving the accuracy of stacking gypsum boards according to different specifications.

[0059] The present invention uses an adaptive stacking structure 3 to position and lift the corresponding gypsum board when the gypsum board of the corresponding size arrives, so as to stack it with the next gypsum board of the corresponding size arriving at the side of the adaptive stacking structure 3. The adaptive stacking structure 3 of the present invention adopts the following preferred embodiment, the adaptive stacking structure 3 includes a driving cabin 31 arranged on the side plate of the classification and transportation structure 2, a lifting frame 32 arranged in the driving cabin 31, a threaded driving rod 33 penetrating the lifting frame 32, and a connecting driving motor 34 arranged on the threaded driving rod 33; a threaded groove for threaded connection of the threaded driving rod 33 is vertically arranged in the lifting frame 32, and the threaded driving rod 33 is connected to the output end of the connecting driving motor 34.

[0060] In the above embodiment, the connecting drive motor 34 can control the overall lifting state. The connecting drive motor 34 drives the threaded drive rod 33 to rotate. Under the rotation of the threaded drive rod 33, the lifting frame 32 rises or falls, thereby driving the positioning clamping part to rise or fall.

[0061] In order to clamp the gypsum board, the present invention also has the following designs: Figure 2 and Figure 3As shown, a clamping top plate 35 is movably provided inside both sides of the outer end of the lifting frame 32, and a clamping bottom plate 36 is connected to the bottom of the clamping top plate 35. The clamping top plate 35 is vertically arranged, and the clamping bottom plate 36 is inclined, and the distance between the bottoms of the clamping bottom plates 36 is greater than the distance between the clamping top plates 35; a clamping drive cylinder 37 is provided on the lifting frame 32, and the clamping top plate 35 is connected to the output end of the clamping drive cylinder 37.

[0062] In order to avoid secondary deviation during the transportation of the gypsum board, and in order to verify that the current gypsum board is a gypsum board of corresponding size, the present invention first allows the gypsum board to enter through the inclined clamping bottom plate 36. In the above embodiment, the distance between the clamping top plates 35 is slightly larger than the length of the gypsum board, and the clamping top plate 35 and the clamping bottom plate 36 can follow the lifting frame 32 to rise and fall. During the descent, the gypsum board gradually approaches the clamping bottom plate 36 and enters between the clamping bottom plates 36. Under the limiting action of the clamping bottom plate 36, the upper end of the gypsum board gradually enters between the clamping top plates 35. Then, the clamping drive cylinder 37 drives the clamping top plate 35 to gradually approach the gypsum board and abut against the gypsum board, thereby clamping the gypsum board.

[0063] In order to identify whether the size of the current gypsum board matches and to buffer the clamping process of the gypsum board, the present invention also makes the following designs: Figure 3 , Figure 4 and Figure 5 As shown, a mounting groove 38 is provided in the clamping top plate 35, and a movable inner plate 39 is provided on the inner side of the clamping top plate 35. The movable inner plate 39 is movably provided in the mounting groove 38. A connecting spring 310 is provided on the side of the movable inner plate 39 close to the mounting groove 38, and the movable inner plate 39 is connected to the inside of the mounting groove 38 through the connecting spring 310; an inclined plate 311 is provided at the bottom of the movable inner plate 39, and the end of the inclined plate 311 is inclined, and the end of the inclined plate 311 extends into the mounting groove 38.

[0064] In the above embodiment, Figure 3 As shown, during the process of the gypsum board gradually entering between the clamping top plates 35, the gypsum board gradually contacts the inclined plate 311 and moves along the inclined plate 311 to between the movable inner plates 39. If the gypsum board has a corresponding size, the gypsum board can smoothly enter between the movable inner plates 39 and squeeze the movable inner plates 39 inwardly. Then, the clamping drive cylinder 37 drives the clamping top plate 35 to move inwardly. During this process, the movable inner plate 39 always contacts the gypsum board, and the connecting spring 310 is continuously squeezed until it is squeezed to the shortest state. At this time, the gypsum board is fully clamped, as shown in FIG. Figure 4As shown, if the size of the gypsum board is smaller than the corresponding size, it will directly enter between the movable inner plates 39 during the upward movement, and will not contact the inclined plate 311, and the side wall of the gypsum board will not abut against the movable inner plate 39. At this time, there is a certain distance between the inner wall of the limiting space 5 and the gypsum board, and it is judged that the gypsum board is not of matching size, such as Figure 5 As shown, if the size of the gypsum board is larger than the corresponding size, it will be blocked between the clamping bottom plates 36 when entering the movable inner plates 39. In this case, the corresponding gypsum board cannot be clamped. The above structure performs a secondary verification on the gypsum boards of corresponding sizes to avoid problems in the recognition process of the image acquisition and processing module 4, which may cause gypsum boards of non-matching sizes to be transported to the corresponding adaptive stacking structure 3 for stacking.

[0065] In addition, in order to directly perform a secondary verification on whether the gypsum board is of matching size, the present invention also makes the following design: an elastic force sensor 312 is provided on the connecting spring 310, and an infrared sensor 313 is installed on the inner side of the movable inner plate 39. The elastic force sensor 312 and the infrared sensor 313 are both communicated with the image acquisition and processing module 4. The image acquisition and processing module 4 stores a preset elastic force value and a preset distance value. The image acquisition and processing module 4 compares the data collected by the elastic force sensor 312 with the preset elastic force value, and compares the data collected by the infrared sensor 313 with the preset distance value, and judges the abnormality of the gypsum board size data according to the comparison result.

[0066] In the above embodiment, when the data collected by the elastic force sensor 312 is inconsistent with the structure of the preset elastic force value or the data collected by the infrared sensor 313 is inconsistent with the preset distance value, it means that the size of the gypsum board is abnormal and may not be compatible with the current adaptive stacking structure 3, and the current stacking work needs to be stopped.

[0067] The present invention loads the gypsum board through a pre-adjusting feeding structure 1, and offset-adjusts the position of the gypsum board on the pre-adjusting feeding structure 1. The pre-adjusting feeding structure 1 of the present invention adopts the following preferred embodiment, the pre-adjusting feeding structure 1 includes a feeding roller 11, a first driving shaft 12 arranged on the feeding roller 11, and a first driving motor 13 connected to the first driving shaft 12; the first driving shaft 12 is connected to the output end of the first driving motor 13, and a plurality of feeding rollers 11 are arranged, and a first limit switch 14 is arranged on the feeding roller 11 at the starting end, and a second limit switch 15 is arranged on the feeding roller 11 at the discharging end.

[0068] In the above embodiment, the first drive motor 13 drives the first drive shaft 12 to rotate, thereby driving the loading roller 11 to rotate, so as to realize the transportation of the gypsum board. The first limit switch 14 and the second limit switch 15 are both used to monitor the position of the gypsum board. When the first limit switch 14 detects that the gypsum board has reached the loading roller 11, the driving of the loading roller 11 is stopped with a delay, so that the gypsum board stops at a specified position, usually at the center position, to facilitate image acquisition by the image acquisition and processing module 4.

[0069] In order to adjust the position of the gypsum board, the present invention further has the following design: adjusting cylinders 16 are provided on both sides of the feeding roller 11, and the output end of the adjusting cylinder 16 is connected to an adjusting plate 17, and the inner end surface of the adjusting plate 17 abuts against the gypsum board.

[0070] In the above embodiment, the adjusting cylinder 16 is driven to move the adjusting plate 17 inwardly to abut against the gypsum board. During the inward movement, the offset gypsum board is adjusted so that the gypsum board is aligned with the feeding roller 11.

[0071] The present invention receives the gypsum boards conveyed by the pre-adjusting loading structure 1 through the classification transport structure 2, and transports the gypsum boards, and transports the gypsum boards with corresponding sizes to the sides of the corresponding adaptive stacking structure 3. The classification transport structure 2 of the present invention adopts the following preferred embodiments, the classification transport structure 2 includes a conveying roller 21 arranged at the discharge end of the pre-adjusting loading structure 1, a second driving shaft 22 arranged on the conveying roller 21, and a second driving motor 23 connected to the second driving shaft 22; the second driving shaft 22 is connected to the output end of the second driving motor 23, and the conveying roller 21 is arranged in a plurality of numbers, and a third limit switch 24 is arranged on the conveying roller 21 located at the starting end, and a fourth limit switch 25 is arranged on the conveying roller 21 located at the discharge end.

[0072] In the above embodiment, the second drive motor 23 drives the second drive shaft 22 to rotate, thereby driving the conveying roller 21 to rotate, so as to realize the transportation of the gypsum board. The third limit switch 24 and the fourth limit switch 25 are both used to monitor the position of the gypsum board. When the gypsum board reaches the conveying roller 21, the third limit switch 24 can monitor and feedback to the image acquisition and processing module 4. The image acquisition and processing module 4 delays the control of the conveying roller 21 to stop transportation according to the feedback information, so that the gypsum board stops at the corresponding position of the adaptive stacking structure 3.

[0073] The present invention collects the image of the gypsum board through the image acquisition and processing module 4 to calculate the offset data and size of the gypsum board. The image acquisition and processing module 4 of the present invention adopts the following preferred embodiment, the image acquisition and processing module 4 includes an image acquisition element 41 and a PLC processor arranged above the feeding roller 11; the image acquisition element 41 collects the image of the gypsum board, and calculates the offset data of the gypsum board and feeds it back to the PLC processor. The PLC processor stores the offset preset value, and controls the drive of the adjustment cylinder 16 according to the offset preset value and the offset data.

[0074] In the above embodiment, when the offset data does not match the preset offset value, the PLC processor needs to drive the adjustment cylinder 16 to achieve lateral adjustment. As for the offset in the gypsum board transportation direction, it can be adjusted by the first drive motor 13.

[0075] In addition, after the offset adjustment is completed, the gypsum board is imaged again through the image acquisition element 41. The image acquisition element 41 identifies the size of the corresponding gypsum board based on the normal offset data, and feeds back to the PLC processor. The PLC processor controls the driving of the second drive motor 23 based on the size of the gypsum board, and drives the gypsum board to be transported to the corresponding adaptive stacking structure 3. The PLC processor sends a stacking prevention signal to the adaptive stacking structure 3 based on the abnormal result of the gypsum board size re-inspection.

[0076] In the above embodiment, specific sizes are pre-stored in the PLC processor, and if they match the corresponding sizes, they are transported to the corresponding adaptive stacking structure 3 through the classification and transportation structure 2. The corresponding third limit switch 24 can be used to detect whether the corresponding gypsum board has reached the front of the adaptive stacking structure 3, and the transportation status of the classification and transportation structure 2 can be controlled.

[0077] In summary, the main implementation process of the present invention is:

[0078] The gypsum board is transported and loaded; the first drive motor 13 drives the first drive shaft 12 to rotate, thereby driving the loading roller 11 to rotate, so as to transport the gypsum board. When the first limit switch 14 detects that the gypsum board has reached the loading roller 11, the driving work of the loading roller 11 is stopped for a time delay, so that the gypsum board stops at the image acquisition element 41;

[0079] Image acquisition and recognition of the gypsum board: the image acquisition element 41 acquires the image of the gypsum board, calculates the offset data of the gypsum board and feeds it back to the PLC processor. The PLC processor controls the adjustment cylinder 16 to drive according to the offset preset value and the offset data, and adjusts the offset of the gypsum board;

[0080] After the offset adjustment is completed, the image acquisition element 41 is used to acquire an image of the gypsum board. The image acquisition element 41 identifies the size of the corresponding gypsum board based on the normal offset data and feeds it back to the PLC processor.

[0081] Transporting the gypsum board: the PLC processor controls the second drive motor 23 to drive the gypsum board to the corresponding adaptive stacking structure 3 based on the size of the gypsum board;

[0082] The adaptive stacking structure 3 performs stacking: the connecting drive motor 34 drives the threaded drive rod 33 to rotate. Under the rotation of the threaded drive rod 33, the lifting frame 32 descends, thereby driving the clamping top plate 35 and the clamping bottom plate 36 to descend, so that the gypsum board gradually enters between the clamping top plates 35. During this process, the gypsum board gradually contacts the inclined plate 311 and moves along the inclined plate 311 to between the movable inner plates 39. Then, the clamping drive cylinder 37 drives the clamping top plate 35 to move inward, and the connecting spring 310 is continuously squeezed until it is squeezed to the shortest state. At this time, the gypsum board is fully clamped, and the connecting drive motor 34 is driven in the reverse direction to drive the lifting frame 32 to move upward, thereby driving the gypsum board to move upward. When the next gypsum board of the same size arrives at this position, the connecting drive motor 34 and the clamping drive cylinder 37 are driven in sequence to drive the gypsum board to stack, and then it is transported out through the conveying roller 21.

[0083] The present invention also provides a gypsum board stacking method with a size verification function, comprising the following steps:

[0084] Step 100, collecting an image of the gypsum board arriving at the pre-adjustment feeding structure 1 to calculate the offset value of the gypsum board;

[0085] Step 200, the PLC processor controls the adjustment cylinder 16 to drive according to the offset preset value and the offset data to adjust the offset of the gypsum board;

[0086] Step 300, collecting an image of the gypsum board after adjustment, and calculating the size of the gypsum board based on the image of the gypsum board after adjustment;

[0087] Step 400, the PLC processor controls the second drive motor 23 to drive the gypsum board based on the size of the gypsum board, so as to drive the gypsum board to be transported to the corresponding adaptive stacking structure 3;

[0088] Step 500, the adaptive stacking structure 3 moves downward, the gypsum board enters the limited space, the distance between the limited space 5 and the gypsum board is detected, and the size data of the gypsum board is determined;

[0089] Step 600, based on the abnormal result of the gypsum board size judgment, stacking is stopped, and based on the normal situation of the gypsum board size re-inspection, the corresponding gypsum board is lifted, and when the next gypsum board of the same size arrives at the side of the adaptive stacking structure 3, the gypsum board is driven down to complete the stacking, and the material is discharged after stacking.

[0090] In step 600, it is also necessary to determine whether there are boards on the adaptive stacking structure 3. When there are boards on the adaptive stacking structure 3, stacking is performed and then transported out through the conveying roller 21. If there are no boards, the corresponding gypsum boards are lifted to facilitate subsequent stacking.

[0091] The above situation assumes that two gypsum boards are stacked. In actual application, three or more gypsum boards are usually stacked to form a gypsum board stack. A certain number of gypsum boards n in the gypsum board stack can be set. At this time, in step 600, it is necessary to determine whether the number of boards on the adaptive stacking structure 3 is (n-1). If so, (n-1) gypsum boards are stacked on the gypsum board on the conveying roller 21 for unloading. If the number is less than (n-1), the gypsum board on the conveying roller 21 needs to be clamped by the adaptive stacking structure 3. During the clamping process, multiple gypsum boards need to be stacked on the gypsum board first, and then the gypsum board stack is positioned, clamped and moved upward. In this process, the specifications of the gypsum boards are mainly detected twice by the infrared sensor 313. In addition, in actual application, small gypsum boards will not be clamped by the movable inner plate 39, and large gypsum boards cannot enter the corresponding limit space 5, which completely avoids the situation where gypsum boards of different sizes enter the limit space 5.

[0092] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
