Description

Technical Field

[0001] The present invention relates to the field of plate production, and in particular to a plate production line. Background Art

[0002] Currently, the primary processing of lumber typically involves cutting a whole log of wood along its circumference into sheets of uniform thickness. These sheets then undergo preliminary flattening, air-drying or drying, and trimming to produce individual sheets. Because these sheets are cut from a single log, they inevitably exhibit some degree of warping. The final step in the lumber production process typically involves stacking a certain number of sheets into piles, which are then transferred manually or by external handling equipment and stacked according to a specific orientation. This stacking of sheets is necessary for easy transportation.

[0003] However, in the current plate production process, workers generally stack the plates first and then move them off the processing production line, which wastes manpower and time, has low work efficiency, and can also cause damage to the plates and produce defective products. Existing plate production lines have almost no stacking equipment that can meet existing production needs. For example, Chinese Patent 201920600444.7 - A stacking conveyor line for floor stacking, in which the conveyor line is simply used to stack the plates one by one in the stacking device, and the stacked plates are transported outward by the conveyor rollers; and in the above patent, after the conveyor rollers transport the plate stacks out, there is no equipment for transferring the plate stacks, so that the stacking conveyor line in the above patent only has the function of stacking the plates one by one, and does not have the function of regularizing the plate stacks in the process of collecting the plates into stacks, nor does it have the function of stacking the plate stacks according to the specified stacking direction. The subsequent stacking of the plate stacks still needs to rely on manual or external equipment for stacking, which is very troublesome. However, manual stacking is labor-intensive and easily damages the plates. If external equipment is used, it is difficult to clamp and stabilize the stacks of warped plates, and it is easy to cause pallet problems during the transfer process. Summary of the Invention

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figures 1 to 13As shown, the present invention provides a plate production line, including a stacking machine 1, a transfer machine 2 and a palletizer 3, wherein the stacking machine 1 includes a clamping device 11, a plate connecting device 12 and a plate receiving device 13 arranged at the output end of the clamping device 11, the clamping device 11 is used to clamp and convey plates one by one; the plate connecting device 12 is located on both sides of the output end direction of the clamping device 11 and is provided with receiving guide plates 121 that can be opened and closed toward each other, and the two groups of the receiving guide plates 121 can cooperate with each other to adjust the positions of the plates on both sides along the conveying direction and guide the plates to be stacked on the plate receiving device 13 from bottom to top. The transfer machine 2 is used to receive the stack of plates output by the plate receiving device 13 and output the stack of plates outward; the stacker 3 includes a moving device 31, a rotating device 32 and a clamping device, the output end of the moving device 31 can drive the rotating device 32 to achieve spatial displacement, the clamping device can be rotatably mounted on the rotating device 32, the clamping device includes a driving connecting rod assembly 33 and at least one pair of clamping and supporting mechanisms 34 that can open and close toward each other, the output end of the driving connecting rod assembly 33 can drive each pair of the clamping and supporting mechanisms 34 to open and close, clamp and hold up the stack of plates output by the transfer machine 2. It should be noted that the plates stacked and transported in this application are mainly plate blanks that have not yet been pressed and formed, so there is basically a warping phenomenon. At the same time, single plate blanks are easy to deform due to their large unfolding area. For this reason, the receiving guide plate 121 in the present application can, to a certain extent, limit the two sides of the sheet output by the clamping and feeding device 11 to prevent the sheet from jumping. After the sheet is completely sent out of the clamping and feeding device 11, the two side edges of the sheet are limited by the two groups of receiving guide plates 121. Since the support of the clamping and feeding device 11 is lost, the sheet will fall downward along the guide direction of the two groups of receiving guide plates 121 and enter the plate receiving device 13, thereby achieving orderly stacking of the sheets one by one. For this reason, at least one pair of clamping and supporting mechanisms 34 is used in the present application to cooperate with each other to clamp and support the two side edges of the sheet stack. During the clamping process, the flatness of the contact surface between the sheet stack and the clamping and supporting mechanisms 34 can be effectively adjusted from the opening and closing direction of the clamping and supporting mechanisms 34, thereby achieving the effect of adjusting and leveling the sheet stack. After each pair of clamping and supporting mechanisms 34 is clamped in place, the clamping and supporting mechanisms 34 can also support the edge portions of both sides of the entire sheet stack, thereby preventing the sheet stack from falling off or being clamped unstable. To achieve the effect of clamping and supporting the stack of plates, the clamping and supporting mechanism 34 in this application is a conventional hook block structure, which can simultaneously adjust both sides of the plate stack and support the bottom of both sides of the plate stack. The specific structure of the clamping and supporting mechanism 34 is described in detail below and will not be described in detail in this application.

[0039] See also Figures 1 to 5The stacking machine 1 also includes a first frame 14, the clamping device 11 is rotatably mounted on the first frame 14, and the first frame 14 is provided with a stacking area 15 in the direction of the output end of the clamping device 11. The plate collecting device 13 is telescopically arranged at the bottom of the stacking area 15 along the conveying direction of the clamping device 11, and receives the stack of plates; the two groups of receiving guide plates 121 are arranged on both sides of the stacking area 15 in the direction of the output end of the clamping device 11 and can be opened and closed toward each other, and the input end of the transfer machine 2 can receive the stack of plates output by the stacking area 15. In the present application, a conveying mechanism 16 is further provided at the input end of the clamping device 11, wherein the conveying mechanism 16 includes a flat conveyor belt 161 and an adjustable conveyor belt 162 capable of adjusting the conveying angle. The flat conveyor belt 161 is rotatably mounted on the first frame 14, and the adjustable conveyor belt 162 is rotatably mounted on an adjusting frame 163. One end of the adjusting frame 163 is hinged to the first frame 14, and adjusting cylinders 164 are provided on both sides of the output end of the adjusting frame 163 to adjust the output angle of the adjusting conveyor belt 162. In the present application, the adjustable conveyor belt 162 is connected between the clamping devices 11 and is used to feed the plates to the clamping devices 11. It should be noted that in the present application, the stacking area 15 is limited by two groups of the receiving guide plates 121, the plate collecting device 13, the output end of the clamping device 11 and the first frame 14, wherein the two groups of the receiving guide plates 121 are placed on both sides of the stacking area 15 along the plate conveying direction, and the first frame 14 is arranged at the front end of the stacking area 15 along the plate conveying direction. Similarly, the plate collecting device 13 is placed at the bottom of the stacking area 15 for supporting the stacking of plates.

[0040] See further Figure 3 and Figure 4The clamping and conveying device 11 is provided with a bottom belt 111 and a top belt 112 that cooperates with the bottom belt 111 to clamp and convey the plates. The bottom belt 111 and the top belt 112 are both rotatably mounted within the first frame 14. The top belt 112 is longer than the bottom belt 111 and extends along the plate conveying direction, spanning above the stacking area 15. The plate collecting device 13 is telescopically arranged in front of and below the output end of the bottom belt 111 along the conveying direction of the clamping and conveying device 11. Two sets of receiving guide plates 121 are respectively arranged in parallel on both sides of the output end of the bottom belt 111. The end of the bottom belt 111 is connected to the output end of the above-mentioned adjusting conveyor belt 162. Of course, in order to prevent the plates from curling up after being output from the conveyor belt 162 but before entering the bottom belt 111, in one embodiment of the present application, a follower belt is provided above the output end of the adjusting conveyor belt 162 and the bottom belt 111 to prevent the plates output from the adjusting conveyor belt 162 from curling up. In the present application, the top belt 112 is longer than the bottom belt 111. The main purpose is to prevent the plates from flying upward after the bottom belt 111 is completely output, while ensuring that the plates fall smoothly between the two sets of receiving guides 121. After the plates are output from the clamping and conveying space between the bottom belt 111 and the top belt 112, they will fly towards each other. For this reason, in the present application, the first frame 14 is located at the front end of the conveying direction of the clamping and conveying device 11 and is provided with a tongue depressor 17. The tongue depressor 17 is tilted, wherein the end of the tongue depressor 17 close to the clamping and conveying device 11 is higher than the other end away from the clamping and conveying device 11. This design facilitates the plates of the clamping and conveying device 11 to be guided to fall into the stacking area 15.

[0041] In one embodiment of the present application, after the plate collecting device 13 receives a certain number of plates, since most of the plates are warped, in order to better enable the plate collecting device 13 to receive more plates, a downward pressing mechanism 18 is provided on the top of the stacking area 15, wherein the downward pressing mechanism 18 can be realized by using a cylinder or a linear motor to drive a pressing frame.

[0042] See further Figure 5The plate receiving device 12 includes a first drive motor 124, a crank-connecting rod assembly 122, and a swing shaft 123 rotatably mounted on the first frame 14 on either side of the stacking area 15. The swing shaft 123 is parallel to the conveying direction of the pinching and conveying device 11. The output end of the first drive motor 124 is connected to one end of the crank-connecting rod assembly 122, and the other end of the crank-connecting rod assembly 122 is eccentrically connected to the swing shaft 123 on either side of the stacking area 15. The first drive motor 124, via the crank-connecting rod assembly 122, can drive the swing shaft 123 to swing about its own axis. The receiving guide plates 121 are mounted on the swing shaft 123. The two sets of receiving guide plates 121 can open and close relative to each other about the axis of the swing shaft 123 to accommodate plates conveyed from different positions by the pinching and conveying device 11, thereby achieving the purpose of adjusting the plates. It should be noted that the crank-connecting rod assembly 122 can be a conventional crank-connecting rod structure, as long as it can achieve the swing shaft 123's swing about its own axis. However, in one embodiment of the present application, the crank-connecting rod assembly 122 includes a crank 1221, a first connecting rod 1222, a swing shaft 1223, a lifting rod 1224, and a linkage rod 1225 eccentrically connected to the swing shaft 123. The swing shaft 1223 is horizontally mounted on the first frame 14 and located above the clamping device 11. V-shaped connecting blocks 1226 are provided at both ends of the swing shaft 1223. In addition, the crank 1221 is mounted on the output end of the first drive motor 124, and one end of the first connecting rod 1222 is eccentrically hinged to the crank 1221, and the other end is hinged to one end of the V-shaped connecting block 1226. The other end of the V-shaped connecting block 1226 is hinged to one end of the lifting rod 1224, and the other end of the lifting rod 1224 is hinged to the linkage rod 1225. The other end of the swing shaft 1223 can also be eccentrically hinged to another set of lifting rods 1224, so that the swing shafts 123 on both sides can be linked together. Its working principle is that after the above-mentioned first drive motor 124 rotates, it first drives the crank 1221 to rotate, and the eccentric action of the crank 1221 drives the first connecting rod 1222 to reciprocate and push the swing shaft 1223 to swing around its own axis. Then, after the V-shaped connecting block 1226 drives the swing shaft 1223 to swing, the swing shaft 123 drives the lifting rod 1224 to drive the swing shaft 123 to swing around its own axis, and finally achieves the function of adjusting the opening and closing of the receiving guide plates 121 on both sides.

[0043] See also Figures 3 to 5In this application, the plate collecting device 13 primarily supports the stack of plates in the stacking area 15 and can be simply understood as acting as a switch between the stacking area 15 and the transfer machine 2. To this end, the plate collecting device 13 described in this application includes a support fork 131 and a telescopic mechanism. The support fork 131 is slidably mounted on the first frame 14 along the conveying direction of the plates. The output end of the telescopic mechanism can drive the support fork 131 into the stacking area 15 to receive the plates, or the output end of the telescopic mechanism can drive the support fork 131 out of the stacking area 15 to unload the received stack of plates onto the input end of the transfer machine 2. The telescopic mechanism can be a telescopic cylinder or screw structure. Of course, since the support fork 131 carries a relatively large stack of plates, and the entire plate is in a high-dust environment, the telescopic mechanism in the application includes a third servo motor 132, a third chain 133 and a third sprocket 134, wherein the third sprocket 134 is rotatably mounted on the first frame 14, and the third chain 133 is wound around the third sprocket 134 and the third servo motor 132, wherein the transmission direction of the third chain 133 is consistent with the telescopic direction of the support fork 131. In this application, the telescopic direction of the support fork 131 is the clamping direction of the clamping device 11.

[0044] See also Figure 1 and Figure 6 In the present application, the transfer machine 2 includes a third frame 21, fourth sprockets 22 arranged on both ends of the third frame 21, and a fourth chain 23 wrapped around the fourth sprockets 22 at both ends. It should be noted that the above-mentioned fourth sprockets 22 and fourth chains 23 are provided on both sides of the third frame 21, and the two sets of structures can be driven by the same driving structure 25, such as a conventional rotating motor. The two ends of the third frame 21 are respectively connected between the stacking area 15 and the palletizer 3. In the present application, in order to better receive the stack of plates sent out from the stacking area 15, the third frame 21 is provided with a lifting frame 24 directly below the stacking area 15. When the stacked plates in the stacking area 15 reach a preset number, the lifting frame 24 rises until it contacts the support fork 131, and the telescopic mechanism drives the support fork 131 to retract. At this time, the stack of plates in the stacking area 15 is restricted by the cooperation of the first frame 14 and the two groups of receiving guide plates 121, so that the stack of plates can fall directly onto the lifting frame 24. At this time, the lifting frame 24 descends, so that the stack of plates can fall onto the fourth chains 23 on both sides of the third frame 21. At this time, the lifting frame 24 continues to descend until the stack of plates completely falls onto the fourth chain 23, and then the driving structure 25 drives the stack of plates on the two fourth chains 23 into the palletizer 3.

[0045] See also Figure 1 、 Figure 2 、 Figures 7 to 13The moving device 31 includes a second frame 311 and a moving frame 312 slidably mounted on the second frame 311. The second frame 311 is provided with a first driving component 313, and the first driving component 313 can drive the moving frame 312 to slide on the second frame 311; the rotating device 32 can be lifted and lowered on the moving frame 312, and the moving frame 312 is provided with a second driving component 314 for lifting and lowering the rotating device 32. The third frame 21 extends into the second frame 311, which makes it easier for the clamping device to clamp. In order to enable the clamping device to move in space, the first driving component 313 and the second driving component 314 can be simple drive structures such as cylinders or linear motors. Of course, it can also be a structure in which a motor drives the screw to rotate, which is not described in detail here.

[0046] See also Figure 7 and Figure 8 In some embodiments of the present application, the first drive assembly 313 includes a first drive motor 3131, a first reducer 3132, a first chain 3133, and a first sprocket 3134. The first drive motor 3131 and the first reducer 3132 are both mounted on the top of the second frame 311, at one end in the sliding direction of the movable frame 312. The input end of the first reducer 3132 is connected to the output end of the first drive motor 3131, and the first sprocket 3134 is rotatably mounted on the other end of the second frame 311. The first chain 3133 is wound between the output end of the first reducer 3132 and the first sprocket 3134, and the movable frame 312 is connected to the first sprocket 3134 via a connector. The combination of the chain and sprocket can be used in environments with high dust and debris, and has high reliability and stable power transmission. In addition, in the present application, in order to better enable the mobile frame 312 to slide on the second frame 311, in some embodiments of the present application, a track 3111 is designed on the top of the second frame 311. The track 3111 can be made of a traditional slide rail, or a channel steel or steel pipe can be used as the track 3111. Of course, the mobile frame 312 is equipped with a roller structure 3123 that matches the track 3111, which improves the applicability of the present device in highly polluted or dusty environments. In the present application, the second frame 311 is a frame structure, which is convenient for installing other structures thereon and docking other processing equipment.

[0047] See also Figure 7 and Figure 8In one embodiment of the present application, the second driving assembly 314 includes a second driving motor 3141, a second reducer 3142, a second chain 3143 and a second sprocket 3144. The second driving motor 3141 and the second reducer 3142 are both installed on the top of the mobile frame 312, the input end of the second reducer 3142 is connected to the output end of the second driving motor 3141, and the second sprocket 3144 is rotatably installed on the bottom of the mobile frame 312; the second chain 3143 is wound between the output end of the second reducer 3142 and the second sprocket 3144, and the clamping device is connected to the second sprocket 3144 through a connecting member.

[0048] See also Figures 9 to 11 The clamping device includes a rotating frame 35 rotatably mounted on the output end of the rotating device 32, wherein the rotating device 32 includes a base frame 321, a connecting rod mechanism 322 and a rotating assembly 323, the base frame 321 is mounted on the output end of the moving device 31, the connecting rod mechanism 322 and the rotating assembly 323 are mounted on the base frame 321, the rotating frame 35 is rotatably mounted on the base frame 321, the output end of the rotating assembly 323 is eccentrically hinged to the input end of the connecting rod mechanism 322, the output end of the connecting rod mechanism 322 is eccentrically hinged to the rotation center of the rotating frame 35, and the rotating assembly 323 can drive the rotating frame 35 to rotate through the connecting rod mechanism 322. In this application, the mobile frame 312 is a frame structure, and the base frame 321 moves within the mobile frame 312. To this end, the base frame 321 is provided with a pulley mechanism that is slidably mounted on the mobile frame 312. In fact, the pulley mechanism is provided at each of the four corners of the base frame 321. The pulley mechanism restrains the entire base frame 321 within the mobile frame 312 to prevent the base frame 321 from shaking during the lifting or rotation process. Of course, the four side columns of the mobile frame 312 are provided with limiting rails that cooperate with the pulley mechanism. In addition, in order to improve the balance of the lifting and lowering of the base frame 321, a transmission shaft is also provided on the top of the mobile frame 312, and the transmission shaft is installed on the mobile frame 312 through a bearing seat. At the same time, the output end of the second reducer 3142 drives the transmission shaft to rotate through a belt or chain, and a second sprocket 3144 is also provided at both ends of the transmission shaft. At this time, the second chain 3143 is wound around the sprocket of this part and the second sprocket 3144 on the bottom of the mobile frame 312. Such a structural design can realize the synchronous lifting and lowering of the two sides of the base frame 321, thereby improving the balance.

[0049] See also Figure 10 and Figure 11The rotating assembly 323 includes a third reducer 3232 and a third servo motor 3231. The third reducer 3232 is connected to the third servo motor 3231, and the output end of the third reducer 3232 is connected to the input end of the connecting rod mechanism 322. The connecting rod mechanism 322 includes a connecting rod 3221, a rocker arm 3222, and a swing rod 3223. One end of the rocker arm 3222 is hinged to one end of the connecting rod 3221, and the other end of the rocker arm 3222 is fixed to the rotation center of the rotating frame 35. The other end of the connecting rod 3221 is hinged to one end of the swing rod 3223, and the other end of the swing rod 3223 is fixed to the output end of the rotating assembly 323. In addition, to better allow the rotating frame 35 to rotate relative to the base frame 321, a main shaft 351 is provided at the rotation center of the rotating frame 35, and a mounting seat 324 is provided on the base frame 321. The mounting seat 324 is provided with a mounting hole 325. The main shaft 351 is mounted in the mounting hole 325 via a bearing, and the top of the main shaft 351 is connected to the rocker arm 3222. In particular, since the clamped plate is large in size and has great inertia during rotation, the main shaft 351 can be made relatively large to improve stability. At the same time, to prevent external dust from entering the bearing during use, a cover can be installed on the top of the mounting seat 324. In addition, a protective cover can be installed on the entire base frame 321 to reduce external debris from falling into the motion range of the rotating frame 35, the connecting rod mechanism 322, and the rotating device 32, thereby improving protection.

[0050] See further Figures 12 to 13 The clamping and supporting mechanism 34 is hinged on the rotating frame 35. The driving link assembly 33 includes a lever 331, a push rod 332, and a driving mechanism 333. The lever 331 is rotatably mounted on the rotating frame 35. The output end of the driving mechanism 333 is hinged to one end of the lever 331. The driving mechanism 333 can drive the lever 331 to rotate. Both ends of the lever 331 are hinged to one end of at least one set of push rods 332. The other end of the push rod 332 is hinged to the driving end of the clamping and supporting mechanism 34 on the corresponding side. Each set of levers 331 can control the opening and closing of at least one pair of clamping and supporting mechanisms 34 to clamp and support the stack of sheet materials through the push rods 332 connected to it. It should be noted that the driving mechanism 333 in this application is a telescopic cylinder, which is hinged to the rotating frame 35. At the same time, the output end of the driving mechanism 333 is hinged to one side of the lever 331.

[0051] Furthermore, in the present application, the clamping mechanism 34 includes a mounting seat 341, a rotating shaft 342, an L-shaped support plate 343, and a swing arm 344 disposed on the rotating shaft 342. The mounting seat 341 is mounted on one side of the rotating frame 35, the rotating shaft 342 is rotatably mounted on the mounting seat 341, and the L-shaped support plate 343 is mounted on the rotating shaft 342. The outward end of the swing arm 344 is hinged to the output end of the push rod 332. The L-shaped support plates 343 on both sides of the rotating frame 35 are disposed opposite each other, i.e., the horizontal portions of the L-shaped support plates 343 are disposed opposite each other, while the vertical portions are connected to the rotating shaft 342. In another embodiment of the present application, in order to better promote the rotation of the clamping mechanism 34, the push rod 332 is provided with hinge joints 334 at both ends of the push rod 332. The two ends of the push rod 332 are respectively hinged to one end of the lever 331 and the driving end of the clamping mechanism 34 via the hinge joints 334. In this application, the hinge joint 334 is connected to the push rod 332 via a threaded connection. The length of the threaded connection can be adjusted to adjust the actual movement length of the push rod 332. At the same time, because the hinge joint 334 can rotate relative to the push rod 332, it is convenient to effectively use different installation situations when the hinge joint 334 is later connected to other structures, thereby improving installation convenience. In addition, to ensure better movement and avoid jamming during use, the hinge joint 334 and the lever 331 are hinged in this application using a ball joint.

[0052] The L-shaped support plates 343 are moved downwards to contact the stacked plates.

[0053] In addition, in the present application, the swing arm 344 is set in the opposite direction to the L-shaped support plate 343. For this reason, the driving mechanism 333 and the driving connecting rod assembly 33 in the present application are both set on the upper surface of the rotating frame 35, and the working end of the L-shaped support plate 343 extends out of the lower surface of the rotating frame 35. When the L-shaped support plates 343 on both sides cooperate with each other to clamp and support the stack of plates, the horizontal part of the L-shaped support plate 343 plays the role of supporting the plates, and the vertical part of the L-shaped support plate 343 can level the different layers of plates on the plate stack during the opening and closing process of the L-shaped support plate 343, so that the plate stack can be stacked flat.

[0054] The plate production line of the present invention utilizes a receiving guide plate 121 to guide the plates conveyed one by one by the clamping and conveying device 11, so that the plates can be neatly stacked on the plate receiving device 13, and the receiving guide plate 121 can adjust the opening and closing angle to meet the stacking requirements of plates of different specifications. In addition, the mobile device 31 is used as the driving basic structure to drive the rotating device 32 to achieve spatial displacement, thereby improving the flexibility of the entire equipment and adapting to the stacking requirements in different environments. In addition, multiple pairs of clamping and supporting mechanisms 34 that open and close in opposite directions are designed, and the driving connecting rod assembly 33 is used to drive each pair of the clamping and supporting mechanisms 34 to swing in opposite directions to achieve the opening and closing clamping action of each pair of clamping and supporting mechanisms 34, thereby achieving synchronous opening and closing action, avoiding the phenomenon that the clamping and supporting mechanisms 34 are not likely to hook the plate when clamping or unloading in the later stage, thereby improving the quality of plate stacking; at the same time, the clamping and supporting mechanisms 34 are used to clamp and support the edges of the plate stack on both sides, thereby effectively avoiding the phenomenon that the plate stack is unstable due to the presence of warped plates, thereby improving the stability of transportation. This plate production line is cleverly designed to stack plates flatly and can effectively clamp warped plate stacks with great flexibility.
