Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of single board stacking equipment, and more particularly to a single board stacking device without shutdown. BACKGROUND

[0002] In a single board production line, the single board after production and detection needs to be finally stacked and stored. The stacking and storage of the single board needs a single board stacking device to achieve.

[0003] In the prior art, the applicant has applied for a Chinese invention patent with the publication number CN111153153B, which discloses an automatic stacking device for laminated boards. The clamping and conveying mechanism includes a swing frame, a connecting frame, a roller mounting frame, a clamping roller and a clamping roller shaft clamping belt. The swing frame can drive the clamping roller on one side of the connecting frame to turn under the conveying belt, and hold the laminated board from the conveying frame. After the single board is moved to the position, the swing frame is turned to open, and the clamping roller on one side of the connecting frame is driven to leave the conveying belt and turn to the outside, and the held laminated board falls vertically to the collecting device to be stacked.

[0004] However, it is found in actual use that the stacking process cannot be stopped, and when the single board on the collecting device is full, the whole stacking device needs to be shut down, and the single board stack on the collecting device needs to be removed before starting again, so as to continue the stacking operation. The operation is complicated and affects the stacking efficiency. SUMMARY

[0005] To solve the problems of the prior art, the application provides a single board stacking device without shutdown, which can remove the full single board stack on the stacking device without shutdown.

[0006] To achieve the above object, the technical scheme of the present application provides a non-stop single board stacking device, which comprises a control device, a rack, a board collecting mechanism and two groups of conveying and discharging mechanisms, the two groups of conveying and discharging mechanisms are horizontally installed on both sides of the rack along the X-axis direction; each group of conveying and discharging mechanisms comprises a conveyor, a swing rack I and a driving device I, the conveyor is horizontally installed on the rack along the Y-axis direction, the swing rack I is rotationally installed on the rack through the driving device I, and the swing racks I of the two groups of conveying and discharging mechanisms are symmetrically arranged, and the swing rack I is provided with support rollers arranged in parallel at the bottom of the conveyor; the support rollers can be rotated towards the outside of the rack along the X-axis direction and separated from the bottom of the conveyor through the rotation of the swing rack I, or rotated back to the bottom of the conveyor from the outside of the rack along the X-axis direction; each group of conveying and discharging mechanisms further comprises a driving device II and a swing rack II arranged in parallel with the swing rack I, the swing rack II is rotationally installed on the rack through the driving device II, and the swing racks II of the two groups of conveying and discharging mechanisms are symmetrically arranged, the bottom of the swing rack II is provided with a bearing table arranged at the bottom side of the support roller, the board collecting mechanism is located at the bottom of the bearing table of the two groups of swing racks II, and the driving device I, the driving device II and the conveyor are controlled by the control device; the bearing table can be rotated towards the outside of the rack along the X-axis direction through the rotation of the swing rack II, or rotated back to the bottom of the support roller from the outside of the rack along the X-axis direction.

[0007] The single board moves from the self-feeding end to the top of the support roller and moves along the support roller under the driving of the conveyor. When the single board is transported directly above the board collecting mechanism, the driving device I drives the swing rack I to rotate and separate from the bottom of the conveyor, and the single board falls onto the board collecting mechanism for stacking. If the single board on the board collecting mechanism is full, the swing rack II rotates to rotate the bearing table to the bottom of the support roller, temporarily bearing the single board falling from the swing rack I, to leave time for the transfer of the single board stack on the board collecting mechanism. When the transfer of the single board on the board collecting mechanism is completed, the swing rack II is opened again to separate the support table from the bottom of the support roller, and the single board falls onto the board collecting mechanism again for stacking. The whole process provides a window period for the transfer of the single board on the board collecting mechanism without stopping, ensuring the stacking efficiency of the stacking machine.

The extension and retraction of the driving cylinder one can drive all the swing claws one to rotate along the rotating shaft one, so that the support rollers are separated from or placed on the bottom of the conveyor. When the support rollers are placed on the bottom of the conveyor, the single board can move along the support rollers under the driving of the conveyor, and when the support rollers are separated from the bottom of the conveyor, the single board falls from the support rollers to the bearing table or the collecting mechanism for stacking and placing.

[0009] Optionally, the swing frame two comprises a rotating shaft two and a plurality of swing claws two arranged along the Y-axis horizontal direction of the frame, the driving device two is a driving cylinder two, the rotating shaft two is installed on the top of the frame and extends along the Y-axis horizontal direction, the top end of the swing claw two is fixedly connected with the rotating shaft two, and the bottom end of the swing claw two extends to the bottom side of the support rollers as a bearing table. One end of the driving cylinder two is hinged with the frame, and the other end of the driving cylinder two is hinged with the swing claw two. The extension and retraction of the driving cylinder two can drive all the swing claws two to rotate along the rotating shaft two, so that the bearing table is separated from or placed on the bottom of the support rollers. When the bearing table is separated from the bottom of the support rollers, the single board can directly fall onto the collecting mechanism for stacking. When the single boards on the collecting mechanism are full, the bearing table is rotated and placed on the bottom of the support rollers to temporarily bear the falling single boards, so as to leave time for the transfer of the single boards on the collecting mechanism. When the transfer of the single boards on the collecting mechanism is completed, the bearing table is separated from the bottom of the support rollers, and the temporarily stacked single boards continue to fall onto the collecting mechanism for stacking.

[0010] Optionally, the conveyor is a belt conveyor, and the conveyor has a conveying belt arranged in parallel on the top of the support rollers. The belt conveyor is internally provided with a plurality of floating roller assemblies. Each floating roller assembly has a floating roller body vertically and floatingly installed on the frame. The floating roller bodies are arranged in parallel along the Y-axis horizontal direction on the top of the support rollers, and the conveying belt is wound around all the floating roller bodies from the bottom. Each floating roller assembly further comprises a floating frame, a limiting bolt and a limiting nut. The middle part of the floating frame is hinged with the frame, and the floating roller body is installed on one end of the floating frame.

The floating frame can rotate along the frame, so that the floating roller body can float up and down along the frame, so as to adapt to single boards of different thicknesses. The floating roller body and the floating frame can always press the conveying belt on the surface of the single board under the action of their own gravity, so as to ensure the stability of conveying.

Since the floating of the floating roller body will cause the loosening of the conveying belt, the tensioning wheel pulled by the tensioning spring can have a certain floating space, so as to adapt to the tightness of the conveying belt and always ensure the tensioning of the conveying belt. After long-term use, since the tensioning spring will cause the elasticity to decrease due to fatigue, the bottom end of the tensioning spring can be hung in the hanging hole at different heights to extend the extension length of the tensioning spring, so as to ensure the tensioning force of the tensioning spring and prolong the service life of the tensioning spring.

[0013] Optionally, the horizontal adjusting mechanism further comprises a sliding frame and a horizontal adjusting mechanism, the top of the frame is provided with a sliding rail extending along the X-axis horizontal direction, the sliding frame is slidably arranged on the sliding rail through the horizontal adjusting mechanism, and one group of the conveying and discharging mechanisms is installed on the sliding frame; the horizontal adjusting mechanism comprises a hand wheel, a first screw lever, a second screw lever, a third screw lever, a first chain, a second chain, a first sprocket, a second sprocket, a third sprocket and a fourth sprocket, the first screw lever, the second screw lever and the third screw lever are arranged in parallel with the sliding rail, the second screw lever and the third screw lever are located on the two sides of the first screw lever along the Y-axis direction, the first screw lever, the second screw lever and the third screw lever are rotatably arranged on the frame through bearings and bearing seats, and the outer sides of the first screw lever, the second screw lever and the third screw lever are all screwed with screw nuts fixedly connected with the sliding frame; the hand wheel is fixedly installed at the end of the first screw lever, the first sprocket and the second sprocket are fixedly sleeved at the end of the first screw lever close to the hand wheel, the first sprocket is located between the second sprocket and the hand wheel, the third sprocket is fixedly installed at the end of the second screw lever, the fourth sprocket is fixedly installed at the end of the second screw lever, the first chain is closed loop wound around the first sprocket and the third sprocket, and the second chain is closed loop wound around the second sprocket and the fourth sprocket.

[0014] Optionally, a rotation-stopping limiting structure is arranged between the first screw lever and the frame; the rotation-stopping limiting structure comprises a mounting wall, a connecting disc and a rotation-stopping bolt, the mounting wall is fixedly connected with the frame, the mounting wall is located between the first sprocket and the hand wheel, the connecting disc is fixedly connected with the hand wheel and is located between the hand wheel and the mounting wall; a plurality of bolt holes are formed in the connecting disc and are distributed around the axis of the first screw lever, a plurality of limiting holes are formed in the mounting wall and are distributed around the axis of the first screw lever, any bolt hole can be rotationally aligned with any limiting hole, and the rotation-stopping bolt is screwed through any bolt hole and is arranged in the limiting hole aligned with the bolt hole. When the sliding frame is slid to a position suitable for the width of a single board, the rotation-stopping bolt arranged in the bolt hole and the limiting hole opposite to the bolt hole can prevent the first screw lever, the second screw lever and the third screw lever from rotating again, prevent the sliding frame from sliding along the slide rail, and ensure that the position of the sliding frame and the conveying and discharging mechanism on the sliding frame does not change during operation.

[0015] Optionally, the single board collecting mechanism comprises a lifting platform located at the bottom side of the frame and a discharging roller table, the top of the lifting platform is provided with a roller conveyor I extending along the X-axis horizontal direction, and the top of the discharging roller table is provided with a roller conveyor II extending along the X-axis horizontal direction; the roller conveyor I is located directly below the bearing table of the two groups of swing frames II, the discharging roller table and the lifting platform are arranged along the X-axis direction, the lifting platform can drive the roller conveyor I to descend, so that the discharging end of the roller conveyor I and the feeding end of the roller conveyor II are connected with each other, the roller conveyor II extends to the outside of the frame, and the lifting platform, the roller conveyor I and the roller conveyor II are all controlled by the control device.

[0016] The lifting platform can drive the roller conveyor I to ascend and approach the swing frame I and the swing frame II, so as to receive the falling single boards and reduce the falling height of the single boards. As the height of the single board stack gradually increases, the lifting platform can gradually descend to adapt to the height of the single board stack. When the single boards are fully stacked, the lifting platform descends to make the discharging end of the roller conveyor I and the feeding end of the roller conveyor II connected with each other, and the roller conveyor I and the roller conveyor II are started to horizontally transport the single board stack to the outside of the frame, so as to facilitate external hoisting and transfer.

[0019] The conveyor does not stop during the entire stacking process, when the single board is transported to the stacking unit corresponding to the classification position and aligned with the collecting mechanism below, the single board stops advancing under the blocking of the blocking plate of the stacking unit, so as to avoid the single board from continuing to move under the driving of the conveyor, at this time, the opening of the swing rack can make the single board accurately fall and be stacked on the collecting mechanism. The setting of the blocking plate can ensure the accuracy of the falling position of the single board. By installing the connecting frame to different bolt connection holes, the position of the blocking plate along the Y-axis direction can be adjusted to adapt to single boards of different lengths.

The single board is clamped between the baffle two and the alignment plate two of the horizontal cylinder two through the extension and contraction of the horizontal cylinder two, and the inclined single board on the bearing table can be adjusted in the Y-axis direction.

[0022] The technical scheme of the present application has the beneficial effects over the prior art, which are as follows:

[0023] The single board moves from the feeding end to the top of the supporting roller and moves along the supporting roller under the driving of the conveyor. When the single board is transported to the directly above the collecting mechanism, the driving device one drives the swing shelf one to rotate and separate from the bottom of the conveyor, and the single board drops on the collecting mechanism for stacking. If the single board on the collecting mechanism is full, the swing shelf two rotates to drive the bearing table to rotate to the bottom of the supporting roller, temporarily bearing the single board dropped from the swing shelf one, so as to leave time for the transfer of the single board stack on the collecting mechanism.

DETAILED DESCRIPTION

[0042] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0043] Embodiment 1:

[0044] Based on Figures 1 to 7The embodiment shown provides a non-stop single board stacking device, which comprises a control device, a rack 1, a plate collecting mechanism 2 and two sets of conveying and discharging mechanisms 3. The control device adopts a PLC controller, the conveying and discharging mechanism 3 is used for receiving the single board 100 transported by the external conveyor 200 and transporting the single board 100 to the top of the plate collecting mechanism 2, and then releasing the single board 100 to make the single board 100 fall onto the plate collecting mechanism 2 for stacking. In the embodiment, the direction of horizontal conveying of the single board 100 on the conveying and discharging mechanism 3 is the Y-axis direction, and the direction perpendicular to the horizontal conveying direction of the single board 100 on the conveying and discharging mechanism 3 is the X-axis direction.

[0045] The two sets of conveying and discharging mechanisms 3 are horizontally arranged on both sides of the rack 1 along the X-axis direction, each set of conveying and discharging mechanism 3 comprises a conveyor 4, a swing frame 5 and a driving device I. The conveyor 4 is horizontally arranged on the rack 1 along the Y-axis direction, the swing frame 5 is rotatably arranged on the rack 1 by the driving device I, and the swing frames 5 of the two sets of conveying and discharging mechanisms 3 are symmetrically arranged, and the swing frame 5 is provided with support rollers 501 arranged in parallel at the bottom of the conveyor 4. The support rollers 501 can be rotated to the outside of the rack 1 along the X-axis direction by the rotation of the swing frame 5 and separated from the bottom of the conveyor 4, or rotated back to the bottom of the conveyor 4 from the outside of the rack 1 along the X-axis direction. In use, the swing frame 5 is first rotated to make the support rollers 501 located directly below the conveyor 4, the single board 100 transported by the external conveyor 200 is conveyed to the gap between the conveyor 4 and the support rollers 501 along the Y-axis direction, and the two side edges of the single board 100 along the X-axis direction are respectively supported by the support rollers 501 of one set of conveying and discharging mechanism 3 and conveyed by the conveyor 4 on the side. When the single board 100 is conveyed to the top of the plate collecting mechanism 2, the two swing frames 5 are rotated to the outside of the rack 1 along the X-axis direction and the support rollers 501 are separated from the bottom of the conveyor 4, the single board 100 loses the support of the support rollers 501 and falls onto the plate collecting mechanism 2 for stacking. After the single board 100 falls, the support rollers 501 are rotated back to the bottom of the conveyor 4 from the outside of the rack 1 along the X-axis direction to receive the next single board 100.

[0046] On the basis of the above structure, each set of conveying and discharging mechanism 3 further comprises a driving device II and a swing frame II 6 arranged in parallel with the swing frame I 5, the swing frame II 6 is rotatably arranged on the rack 1 by the driving device II, and the swing frames II 6 of the two sets of conveying and discharging mechanisms 3 are symmetrically arranged. The bottom of the swing frame II 6 has a load bearing platform 601 arranged at the bottom side of the support roller 501, the plate collecting mechanism 2 is located at the bottom of the load bearing platform 601 of the two sets of swing frame II 6, the driving device I, the driving device II and the conveyor 4 are controlled by the control device, and the load bearing platform 601 can be rotated to the outside of the rack 1 along the X-axis direction by the rotation of the swing frame II 6, or rotated back to the bottom of the support roller 501 from the outside of the rack 1 along the X-axis direction.

[0047] In the normal stacking process, based on the above structure, the single board 100 is conveyed to the gap between the conveyor 4 and the support rollers 501 along the Y-axis direction, and the two side edges of the single board 100 along the X-axis direction are respectively supported by the support rollers 501 of one set of conveying and discharging mechanism 3 and conveyed by the conveyor 4 on the side. When the single board 100 is conveyed to the top of the plate collecting mechanism 2, the two swing frames 5 are rotated to the outside of the rack 1 along the X-axis direction and the support rollers 501 are separated from the bottom of the conveyor 4, the single board 100 loses the support of the support rollers 501 and falls onto the plate collecting mechanism 2 for stacking. After the single board 100 falls, the support rollers 501 are rotated back to the bottom of the conveyor 4 from the outside of the rack 1 along the X-axis direction to receive the next single board 100. Figure 4As shown, under the control of the control device, the swing frames 6 in the two sets of conveying and unloading mechanisms 3 are initially in an open state, and the bearing platform 601 is detached from the bottom of the support roller 501. After the two sets of swing frames 5 are opened, the single board 100 can fall directly onto the stacking mechanism 2 for stacking. When the single board 100 on the stacking mechanism 2 is full, based on Figure 5 and Figure 6 As shown, the swing frame 6 in the two sets of conveying and unloading mechanisms 3 rotates under the drive of the drive device 2, causing the bearing platform 601 to rotate from the outer side of the frame 1 along the X-axis direction back to the bottom of the support roller 501. When the swing frame 5 opens, the single board 100 falls onto the bearing platform 601 for temporary stacking, leaving a window period for the transfer of the single board 100 on the board receiving mechanism 2. After the single board 100 on the board receiving mechanism 2 has been transferred, based on Figure 7 As shown, the second frame 6 rotates and opens outwards along the X-axis of the frame 1, causing the support platform to detach from the bottom of the support roller 501. The single board 100 then falls back onto the receiving mechanism 2 for stacking. This cycle repeats. The entire process provides a window period for the transfer of single boards 100 on the receiving mechanism 2 without stopping the machine, and avoids the need to stop the machine to transfer the stack of single boards on the receiving mechanism 2, thus ensuring the stacking efficiency of the stacker crane.

[0048] Among them, based on Figure 3 and Figure 8 As shown, the swing frame 5 includes a rotating shaft 502, a support rod 503, and several swing claws 504 arranged horizontally along the Y-axis of the frame 1. The number of swing claws 504 is determined according to the distance the entire device extends horizontally along the Y-axis. The drive device is a drive cylinder 505. The rotating shaft 502 is mounted on the top of the frame 1 and extends horizontally along the Y-axis. Specifically, the rotating shaft 502 is rotatably mounted on the frame 1 via bearings and bearing seats. The top of the swing claws 504 is fixedly connected to the rotating shaft 502. The bottom of the swing claws 504 extends to the bottom of the corresponding conveyor 4. The support rod 503 is arranged in parallel at the bottom of the conveyor 4, and the support rod 503 is fixedly connected to the bottom of all the swing claws 504 in the single set of conveying and unloading mechanisms 3. In this way, the top of all the swing claws 504 is fixedly connected to the rotating shaft 502, and the bottom of all the swing claws 503 is fixedly connected to the support rod 503. Support rollers 501 are arranged and mounted on support rods 503. One end of drive cylinder 505 is hinged to frame 1, and the other end of drive cylinder 505 is hinged to swing claws 504. The extension and retraction of drive cylinder 505 can drive all swing claws 504 to rotate along shaft 502, causing support rollers 501 to detach from or be placed at the bottom of conveyor 4. When support rollers 501 are placed at the bottom of conveyor 4, veneer 100 can move along support rollers 501 under the drive of conveyor 4. When support rollers 501 detach from the bottom of conveyor 4, veneer 100 falls from support rollers 501 onto bearing platform 601 or stacking mechanism 2 for stacking.

[0049] based onFigure 3 and Figure 9 As shown in FIG. 6, the swing frame two 6 includes a rotating shaft two 602 and a plurality of swing claws two 603 arranged along the Y-axis horizontal direction of the frame 1. In the embodiment, the driving device two is a driving cylinder two 604, the rotating shaft two 602 is installed on the top of the frame 1 and extends along the Y-axis horizontal direction, and the rotating shaft two 602 is rotatably installed on the frame 1 through a bearing and a bearing seat. In the embodiment, the swing claws two 603 and the swing claws one 504 are staggered with each other along the Y-axis direction, and the rotating shaft two 602 is located at the bottom of the rotating shaft one 502 to achieve mutual avoidance. The top end of the swing claw two 603 is fixedly connected with the rotating shaft two 602, and the bottom end of the swing claw two 603 extends to the bottom side of the supporting roller 501 as a bearing table 601. One end of the driving cylinder two 604 is hinged to the frame 1, and the other end of the driving cylinder two 604 is hinged to the swing claw two 603. The extension and retraction of the driving cylinder two 604 can drive all the swing claws two 603 to rotate along the rotating shaft two 602, so that the bearing table 601 is separated from or placed on the bottom of the supporting roller 501. When the bearing table 601 is separated from the bottom of the supporting roller 501, the single board 100 can directly fall onto the collecting plate mechanism 2 for stacking. When the single boards 100 on the collecting plate mechanism 2 are stacked, the bearing table 601 is rotated to be placed on the bottom of the supporting roller 501 to temporarily bear the falling single boards 100, so as to leave time for the transfer of the single boards 100 on the collecting plate mechanism 2. When the transfer of the single boards 100 on the collecting plate mechanism 2 is completed, the bearing table 601 is separated from the bottom of the supporting roller 501, and the temporarily stacked single boards 100 continue to fall onto the collecting plate mechanism 2 for stacking.

[0050] Based on Figure 3 and Figure 10 As shown in FIG. 7, the conveyor 4 is a belt conveyor 4, and the conveyor 4 has a conveying belt 401 arranged in parallel on the top of the supporting roller 501. The belt conveyor 4 is internally provided with a plurality of floating roller assemblies 402. The floating roller assembly 402 has a floating roller body 403 vertically and floatingly installed on the frame 1. The floating roller bodies 403 are arranged on the top of the supporting roller 501 along the Y-axis horizontal direction, and the conveying belt 401 is wound on all the floating roller bodies 403 from the bottom. In use, the single board 100 is clamped between the supporting roller 501 and the conveying belt 401, the floating roller body 403 is pressed on the top of the conveying belt 401 to press the conveying belt 401 on the single board 100, so as to ensure the friction between the conveying belt 401 and the single board 100, and the conveying belt 401 drives the single board 100 to move horizontally along the Y-axis direction. The floating roller body 403 can be adapted to different thicknesses of the single board 100 through the floating of the upper and lower positions.

[0051] The floating roller assembly 402 further comprises a floating frame 404, a limiting bolt 405 and a limiting nut 406. The middle part of the floating frame 404 is hinged to the rack 1, the floating roller main body 403 is installed at one end of the floating frame 404, and the center of gravity of the floating frame 404 and the floating roller main body 403 is located at the side of the rotating shaft of the floating frame 404 close to the floating roller main body 403. In this way, the floating roller main body 403 can press the conveying belt 401 tightly on the top surface of the single board 100 through its own gravity. The other end of the floating frame 404 is vertically provided with a through hole 407, the diameter of the through hole 407 is greater than the outer diameter of the limiting bolt 405 and less than the outer diameter of the limiting nut 406, the limiting bolt 405 is vertically installed on the rack 1, the floating frame 404 is slidably sleeved on the outside of the limiting bolt 405 through the through hole 407, and the limiting nut 406 is screwed on the outside of the limiting bolt 405 and is spaced apart and arranged at the bottom of the through hole 407. When the floating frame 404 rotates along the rack 1, the limiting bolt 405 slides relative to the through hole 407. Because the diameter of the through hole 407 is greater than the outer diameter of the limiting bolt 405, there is a certain transverse relative movement allowance between the through hole 407 and the limiting bolt 405 to meet the transverse relative displacement between the floating frame 404 and the limiting bolt 405 caused by the rotation of the floating frame 404. By adjusting the position of the limiting nut 406 on the limiting bolt 405, the maximum floating distance of the floating roller main body 403 can be adjusted.

[0052] Based on Figure 3 and Figure 11 As shown in the figure, the inner side of the conveying machine 4 is further provided with a floating tensioning mechanism 408. The floating tensioning mechanism 408 comprises a tensioning frame 409, a tensioning roller 410 and a tensioning spring 411. The rack 1 is provided with a plurality of hanging holes 412 arranged at different heights. One end of the tensioning frame 409 is hinged to the rack 1, the other end of the tensioning frame 409 is fixedly connected to the top end of the tensioning spring 411, the bottom end of the tensioning spring 411 is provided with a hook 413 hung in any hanging hole 412, the tensioning roller 410 is installed at the middle part of the tensioning frame 409, the top side part of the conveying belt 401 is wound around the bottom part of the tensioning roller 410, and the tensioning roller 410 tensions the conveying belt 401. The tensioning spring 411 allows the tensioning roller 410 to have a certain floating space up and down. Because the floating roller main body 403 will cause the conveying belt 401 to loosen during the up and down floating process, the tensioning roller 410 pulled by the tensioning spring 411 can compensate for the loosening of the conveying belt 401 caused by the up and down floating of the floating roller main body 403, and the tensioning process can follow the floating of the floating roller main body 403 to adapt automatically. The hanging holes 412 are arranged to connect the tensioning spring 411 and the rack 1. The number of the hanging holes 412 can be arranged according to the actual application. In order to facilitate the arrangement of the hanging holes 412, the hanging holes 412 can be provided on the bolts, and then the bolts are screwed on the rack 1. In this embodiment, based on Figure 11As shown, the number of hanging holes 412 is two, and the two hanging holes 412 are arranged at different heights of the rack 1. The bottom end hook 413 of the tension spring 411 can be hung in the hanging hole 412 at the top or the bottom. In actual use, the tension spring 411 is initially hung in the hanging hole 412 at the top. After a long period of use, the elasticity of the tension spring 411 will decrease due to fatigue, and the extension length of the tension spring 411 can be extended by hanging the bottom end hook 413 of the tension spring 411 in the hanging hole 412 at a different height, so as to ensure the tension of the tension spring 411 and prolong the service life of the tension spring 411.

[0053] Further, based on Figure 2 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the sliding rack 102 and the horizontal adjustment mechanism are further included, the top of the rack 1 is provided with a sliding rail 101 extending along the horizontal direction of the X axis, the sliding rack 102 is slidably arranged on the sliding rail 101 through the horizontal adjustment mechanism, and one set of the conveying and discharging mechanism 3 is installed on the sliding rack 102. In this way, the conveying and discharging mechanism 3 installed on the sliding rack 102 can slide along the sliding rail 101 under the driving of the horizontal adjustment mechanism, so as to realize the adjustment of the relative distance along the X axis direction with another set of the conveying and discharging mechanism 3, so as to adapt to single boards 100 of different widths.

[0054] The horizontal adjusting mechanism comprises a hand wheel 701, a screw lever one 702, a screw lever two 703, a screw lever three 704, a chain one 705, a chain two 706, a sprocket one 707, a sprocket two 708, a sprocket three 709 and a sprocket four 710. The screw lever one 702, the screw lever two 703 and the screw lever three 704 are arranged in parallel with the slide rail 101, the screw lever two 703 and the screw lever three 704 are respectively located at two sides of the screw lever one 702 along the Y-axis direction, the screw lever one 702, the screw lever two 703 and the screw lever three 704 are rotatably arranged on the rack 1 through bearings and bearing seats, and the outer sides of the screw lever one 702, the screw lever two 703 and the screw lever three 704 are respectively screwed with the screw nuts 711 fixedly connected with the sliding frame 102. The hand wheel 701 is fixedly installed at the end of the screw lever one 702, the sprocket one 707 and the sprocket two 708 are fixedly sleeved at the end of the screw lever one 702 close to the hand wheel 701, the sprocket one 707 is located between the sprocket two 708 and the hand wheel 701, the sprocket three 709 is fixedly installed at the end of the screw lever two 703, the sprocket four 710 is fixedly installed at the end of the screw lever two 703, the chain one 705 is closed-loop wound around the sprocket one 707 and the sprocket three 709, and the chain two 706 is closed-loop wound around the sprocket two 708 and the sprocket four 710. By manually rotating the hand wheel 701, the screw lever one 702, the screw lever two 703 and the screw lever three 704 can be driven to rotate along the rack 1, so that the screw nut 711 moves along the corresponding screw lever axis, and the sliding frame 102 slides along the slide rail 101. Since the extension distance of the whole device along the Y-axis direction is relatively long, the parallel arrangement of the three screw levers and the sprocket and chain transmission structure are used to realize the translation of the whole sliding frame 102, so as to ensure the stability of the translation. In actual use, since the single boards 100 of the same batch have the same width size, it is only necessary to manually rotate the hand wheel 701 before production to make the relative position of the conveying and discharging mechanism 3 appropriate, and it is not necessary to adjust again during the whole production operation. Since the extension distances of the chain one 705 and the chain two 706 are relatively long, in order to ensure the stability of the transmission, the tension sprocket 717 can be installed on the rack 1 to support and tension the chain one 705 and the chain two 706.

[0055] wherein, based on Figure 14 and Figure 15As shown, the screw lever 702 and the rack 1 are further provided with a rotation-stopping limiting structure to avoid the hand wheel 701 from rotating by itself during the operation of the device. The rotation-stopping limiting structure comprises a mounting wall 712, a connecting disc 713 and a rotation-stopping bolt 714. The mounting wall 712 is fixedly connected with the rack 1, and is located between the sprocket wheel 707 and the hand wheel 701. The connecting disc 713 is fixedly connected with the hand wheel 701, and is located between the hand wheel 701 and the mounting wall 712. A plurality of bolt holes 715 are formed in the connecting disc 713 and are distributed around the axis of the screw lever 702. A plurality of limiting holes 716 are formed in the mounting wall 712 and are distributed around the axis of the screw lever 702. Any bolt hole 715 can be rotationally aligned with any limiting hole 716. In this embodiment, the number of the bolt holes 715 and the limiting holes 716 is six. The rotation-stopping bolt 714 is screwed through any bolt hole 715 and is located in the limiting hole 716 which is aligned with the bolt hole 715. When the sliding frame 102 is slid to a position suitable for the width of the single board 100, the rotation-stopping bolt 714 is screwed in the bolt hole 715 and the limiting hole 716 which are aligned with each other, so that the screw lever 702 cannot rotate relative to the mounting wall 712. Since the mounting wall 712 is fixedly connected with the rack 1, the screw lever 702 cannot rotate relative to the rack 1, the sliding frame 102 cannot slide along the slide rail 101, and the position of the sliding frame 102 and the conveying and blanking mechanism 3 on the sliding frame 102 cannot change during the operation of the device.

[0056] In the embodiment, the rack 1 is further provided with a limiting wall 724 which is arranged in parallel and spaced apart from the mounting wall 712. The mounting wall 712 is provided with a mounting hole one 722, the limiting wall 724 is provided with a mounting hole two 723 which is opposite to the mounting hole one 722, and the lead screw lever one 702 is rotatably arranged through the mounting hole one 722 and the mounting hole two 723. The sprocket one 707 and the sprocket two 708 are integrally arranged and located between the mounting wall 712 and the limiting wall 724. The outer side wall of the lead screw lever one 702 is provided with a boss 725 which is located between the mounting wall 712 and the limiting wall 724, the inner side wall of the mounting hole two 723 is provided with a step one 726 which is arranged towards the boss 725, the lead screw lever one 702 is rotatably arranged at the mounting hole two 723 through the bearing two 719, the outer ring of the bearing two 719 abuts against the step one 726, the end of the sprocket two 708 abuts against the boss 725, and the end of the sprocket one 707 which is away from the sprocket two 708 abuts against the inner ring of the bearing two 719 through the shaft sleeve 721. The end cover 720 is bolted at the mounting hole one 722 from one side of the hand wheel 701 and forms a step two 727 which is arranged towards the boss 725, the lead screw lever one 702 is arranged through the end cover 720, the bearing one 718 is sleeved on the outer side of the lead screw lever one 702, and the outer ring of the bearing one 718 abuts against the step two 727 and the inner ring of the bearing one 718 abuts against the boss 725. In this way, the axial position of the lead screw lever one 702 is limited by the mounting wall 712, the limiting wall 724, the boss 725, the bearing one 718, the bearing two 719, the step one 726, the step two 727, the shaft sleeve 721, and the integrally arranged sprocket one 707 and sprocket two 708, so that the lead screw lever one 702 cannot relatively move axially along the rack 1.

[0057] Further, based on Figures 4 to 7As shown, the receiving mechanism 2 includes a lifting platform 201 located at the bottom side of the frame 1 and a discharge roller platform 202, the top of the lifting platform 201 is provided with a roller conveyor one 203 extending along the horizontal direction of the X axis, and the top of the discharge roller platform 202 is provided with a roller conveyor two 204 extending along the horizontal direction of the X axis. The roller conveyor one 203 is located directly below the bearing table 601 of the two sets of swing shelves two 6, and the discharge roller platform 202 is arranged along the X axis direction with the lifting platform 201. The lifting platform 201 can drive the roller conveyor one 203 to descend, so that the discharge end of the roller conveyor one 203 and the feeding end of the roller conveyor two 204 are connected with each other, and the roller conveyor two 204 extends to the outside of the frame 1. The lifting platform 201, the roller conveyor one 203 and the roller conveyor two 204 are all controlled by the control device. The lifting platform 201 can drive the roller conveyor one 203 to ascend to be close to the swing shelf one 5 and the swing shelf two 6 to receive the falling single board 100, so as to reduce the falling height of the single board 100. Among them, the frame 1 is provided with a photoelectric switch one 103 connected with the control device, the photoelectric switch one 103 is horizontally arranged and located at a specific distance from the top of the lifting platform 201, and the passage of the photoelectric switch one 103 faces the direction of the single board pile. When the single board 100 is stacked to a height reaching the specific distance, the passage of the photoelectric switch one 103 is blocked by the single board pile, indicating that the single board 100 has been stacked on the top of the roller conveyor one 203. The photoelectric switch one 103 transmits a signal to the control device, and the control device sends a signal to the driving device two after receiving the signal, and the driving device two drives the swing shelf two 6 to rotate, so that the bearing table 601 rotates to the bottom of the supporting roller 501 to temporarily receive the subsequent single board 100. At the same time, the control device sends a signal to the lifting platform 201, and the lifting platform 201 descends to make the discharge end of the roller conveyor one 203 and the feeding end of the roller conveyor two 204 connected with each other. When the lifting platform 201 descends to the bottom end, the lifting platform 201 sends a signal to the control device, and the control device sends a signal to the roller conveyor one 203 and the roller conveyor two 204 to start, so as to horizontally transport the single board pile to the outside of the frame 1, so as to facilitate the external lifting and transfer. The roller conveyor two 204 is also provided with a photoelectric switch three (not shown in the figure) facing the top. When the single board pile is transported to the roller conveyor two 204, the photoelectric switch three sends a signal to the control device, and the control device sends a signal to the roller conveyor one 203 and the roller conveyor two 204 to stop, and at the same time, the control device sends a signal to the lifting platform 601 to ascend to a specific height for receiving the falling single board 100. Subsequently, the lifting platform 601 ascends to the control device again to send a signal, and the control device sends a signal to the driving device two, and the driving device two drives the swing shelf two 6 to open, so that the temporarily stacked single board 100 on the bearing table 601 falls onto the roller conveyor two 204. The single board pile on the roller conveyor two 204 can be transferred by external lifting equipment or transportation equipment.It should be noted that, since the single board 100 will pass through the passage of the photoelectric switch 103 during the falling process, the control device needs to be set to send the above-mentioned action signal after the passage of the photoelectric switch 103 is blocked by the single board 100 for a certain time, for example, 0.5 seconds, so as to avoid triggering the above-mentioned action by the falling single board 100.

[0058] Further, based on Figure 1 As shown, the two sets of conveying and discharging mechanisms 3 are combined into a stacking unit 301, the stacking unit 301 has multiple groups, the multiple groups of stacking units 301 are sequentially arranged along the rack 1 along the Y-axis horizontal direction, the feeding end and the discharging end of any two adjacent stacking units 301 are opposite to each other, and the bottom of each group of stacking units 301 is provided with a collecting mechanism 2. Specifically, in the embodiment, the number of stacking units 301 is four groups, which are sequentially arranged along the Y-axis direction. In each group of conveying and discharging mechanisms 3, the conveyors 4 are arranged in parallel on the top of the supporting rollers 501 in all the swing shelves one 5, that is, in the four groups of stacking units 301, the four groups of discharging conveyors 4 on the same side of the X-axis direction share the same set of conveyors 4, and the conveyors 4 penetrate through the four groups of stacking units 301. The single board 100 can be transported to any stacking unit 301 under the driving of the conveyor 4 and stacked on the collecting mechanism 2 of the stacking unit 301. In actual use, the single board stacking device at the end of the whole single board 100 processing line can be classified and linked according to the detection results of the detection device in front of the processing line, for example, according to the different moisture content or size, and cooperates with the control of the control device to transport the single boards 100 of different classifications to different stacking units 301 for classified stacking. After the single board 100 is transported to the corresponding stacking unit 301 by the conveyor 4, the swing shelf one 5 at the stacking unit 301 is opened to make the single board 100 fall onto the corresponding collecting mechanism 2.

[0059] Further, each group of stacking units 301 is also provided with a blocking mechanism 8 and an alignment mechanism. Based on Figure 3 and Figure 16As shown, the material blocking mechanism 8 comprises a connecting frame 801, a vertical cylinder 802 and a blocking plate 803. The frame 1 is provided with a plurality of bolt connection holes 804 near the discharge end of each conveying and discharging mechanism 3. The bolt connection holes 804 are arranged along the Y-axis in the horizontal direction, and the connecting frame 801 is bolted to any one of the bolt connection holes 804. The height of the connecting frame 801 is higher than the top edge of the supporting roller 501. The vertical cylinder 802 is inverted and fixedly installed on the connecting frame 801. The blocking plate 803 is fixedly connected to the bottom output end of the vertical cylinder 802. The vertical cylinder 802 can drive the blocking plate 803 to descend, so that the blocking plate 803 descends to a position with the same height as the gap between the supporting roller 501 and the conveyor 4. Under the driving of the vertical cylinder 802, the blocking plate 803 can descend to block the movement path of the single board 100, or ascend to avoid the movement path of the single board 100. The vertical cylinder 802 is controlled by a control device. The frame 1 is provided with a photoelectric switch 104 connected to the control device, and each group of stacking units 301 is provided with the photoelectric switch 104. The photoelectric switch 104 is located on the incoming side of the material blocking mechanism 8 in the group of stacking units 301, and is arranged on the top of the conveying path of the single board 100. The passage of the photoelectric switch 104 is arranged towards the conveying path of the single board 100. For the non-stop single board stacking device with multiple stacking units 301, the conveyor 4 does not stop during the entire stacking process. When the single board 100 is transported to the stacking unit 301 corresponding to the classification, the control device sends a signal to the vertical cylinder 802 in the stacking unit 301 according to the detection results of the foregoing processes, such as the moisture content detection, so that the vertical cylinder 802 drives the blocking plate 803 to descend to block the movement path of the single board 100. The timing of signal sending is determined by the specific time when the single board 100 moves from the detection process to the stacking unit 301, that is, after the single board 100 is detected in the detection process, a specific time is waited, and then the control device sends a signal when the single board 100 is transported to the corresponding stacking unit 301. The specific time is calculated by the distance from the detection process to the stacking unit 301 and the transportation speed of the single board 100, and is a program built in the control device. The single board 100 stops advancing under the blocking of the blocking plate 803 of the stacking unit 301, so as to avoid the single board 100 continuing to move under the driving of the conveyor 4 and aligning with the collecting mechanism 2 below. The passage of the photoelectric switch 104 is blocked by the single board 100 and sends a signal to the control device. After receiving the signal of the photoelectric switch 104, the control device sends a signal to the driving device 1, and the driving device 1 drives the swing frame 5 to open, so as to accurately drop the single board 100 on the collecting mechanism 2. If the detection results according to the foregoing processes show that the transported single board 100 does not need to be stacked in the stacking unit 301, the blocking plate 803 does not descend to block the movement path of the single board 100, and the swing frame 5 does not open, so that the single board 100 can continue to move to the next stacking unit 301.The setting of the material blocking plate 803 can ensure the accuracy of the falling position of the single board 100. Before the production line works, by installing the connecting frame 801 to different bolt connection holes 804, the position of the material blocking plate 803 along the Y-axis direction can be adjusted to adapt to single boards 100 of different lengths.

[0060] Based on Figure 2 , Figure 3 and Figure 12 , the alignment mechanism includes a baffle plate one 901, a baffle plate two 902, a horizontal cylinder one 903, and a horizontal cylinder two 904. The output end of the horizontal cylinder one 903 is installed with an alignment plate one 905, and the output end of the horizontal cylinder two 904 is installed with an alignment plate two 906. The height positions of the baffle plate one 901, the baffle plate two 902, the horizontal cylinder one 903, and the horizontal cylinder two 904 are flush with the height position of the bearing table 601. The baffle plate one 901, the baffle plate two 902, the horizontal cylinder one 903, and the horizontal cylinder two 904 are used to align the single boards 100 temporarily stacked on the bearing table 601.

[0061] The horizontal cylinder one 903 and the baffle plate one 901 are both installed on the rack 1, and are respectively located at the bottom of the two sets of swing frames one 5 in the corresponding two sets of conveying and dropping mechanisms 3. The horizontal cylinder one 903 extends along the X-axis horizontal direction, and the alignment plate one 905 and the baffle plate one 901 are opposite to each other. The horizontal cylinder two 904 and the baffle plate two 902 are both installed on the rack 1, and the horizontal cylinder two 904 extends along the Y-axis direction. The horizontal cylinder two 904 and the baffle plate two 902 are both located at a position between the corresponding two bearing tables 601 in the X-axis direction, and the baffle plate two 902 is flush with the material blocking plate 803 in the Y-axis direction. The horizontal cylinder two 904 is located at the bottom side of the feeding end of the corresponding swing frame one 5 in the Y-axis direction, and the alignment plate one 905 and the baffle plate two 902 are opposite to each other. When the single boards 100 are temporarily dropped onto the bearing table 601 for stacking, the single boards 100 may be inclined due to the dropping. The single boards 100 can be clamped between the baffle plate one 901 and the alignment plate one 905 of the horizontal cylinder one 903 through the extension and retraction of the horizontal cylinder one 903, so that the inclined single boards 100 on the bearing table 601 can be adjusted in the X-axis direction. The single boards 100 can be clamped between the baffle plate two 902 and the alignment plate two 906 of the horizontal cylinder two 904 through the extension and retraction of the horizontal cylinder two 904, so that the inclined single boards 100 on the bearing table 601 can be adjusted in the Y-axis direction.
