In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0057] As Figures 1 to 13 shown, the present utility model provides an automatic beam unloading device for plywood clamps, which includes a frame body 1, a plywood arranging mechanism 2, a beam unloading clamp mechanism 3 and a clamp transfer mechanism 4. The frame body 1 is provided with a beam clamping position and an unloading position; the plywood arranging mechanism 2 is used to arrange and convey the plywood into the clamp 100 at the beam clamping position; beam unloading clamp mechanisms 3 are correspondingly arranged at both the beam clamping position and the unloading position. The beam unloading clamp mechanism 3 includes a moving driving member 31, a rotating driving member 32 and a rotating member 33. The rotating driving member 32 and the rotating member 33 are arranged at the output end of the moving driving member 31. The output end of the rotating driving member 32 is connected to the rotating member 33. The moving driving member 31 drives the rotating member 33 to approach or move away from the clamp 100, and the rotating driving member 32 drives the rotating member 33 to rotate so as to tighten or loosen the nut on the clamp 100; the clamp transfer mechanism 4 includes a transfer driving member 41, and a clamp fixing member 43 capable of clamping the clamp 100 is arranged at the output end of the transfer driving member 41. The transfer driving member 41 drives the clamp fixing member 43 to move back and forth between the beam clamping position and the unloading position so as to transfer the clamp 100.

[0058] The plywood to be clamped is placed in the clamp 100 at the clamping position through the board receiving mechanism 2, and then the rotating member 33 can be driven to approach the nut on the clamp 100 by the moving driving member 31, and then the rotating member 33 can be driven to rotate by the rotating driving member 32, and then the nut can be tightened to enable the clamp 100 to clamp the plywood; similarly, the nut can be loosened through the clamping and unclamping mechanism 3 corresponding to the unclamping position to detach the dried plywood from the clamp 100, and then the clamp 100 at the unclamping position can be transferred to the clamping position through the clamp transfer mechanism 4 to fix the next batch of plywood, thereby automatically realizing the steps of placing the plywood, clamping, unclamping and transferring the clamp 100, thereby improving efficiency.

[0059] like Figures 1 to 5 As shown, in some embodiments, the board collecting and sorting mechanism 2 includes a support bar 21, a board collecting turntable 22, a transfer assembly 23 and a lifting assembly 24. The two support bars 21 are spaced apart below the clamping position to receive the plywood. It should be noted here that the frame 1 includes a bracket and a plate body on the bracket. The plate body is provided with openings corresponding to the clamping position and the unclamping position. When the clamp 100 is located at the opening on the plate body, the plywood can enter and exit the clamp 100 from the opening. The plate collecting turntable 22 is rotatably arranged on the frame 1, and is located at one end of the support bar 21 and between the two support bars 21. The outer periphery of the plate collecting turntable 22 is provided with a bracket 221 for accommodating plywood. When the plate collecting turntable 22 rotates, the plywood horizontally transferred from the outside can be placed upright on the support bar 21. The transfer assembly 23 is configured to transfer the multiple plywoods on the support bar 21 to the bottom of the clamp 100 at the clamping position, and the lifting assembly 24 is configured to lift the plywood under the clamp 100 into the clamp 100. Furthermore, a photoelectric switch 25 for counting is arranged on the frame 1, so as to count the plywoods placed on the support bar 21 by the plate collecting turntable 22 rotating.

[0060] In order to prevent the plywood from tipping over when it is in an upright position, the support bar 21 includes a first section 211, a second section 212 and a third section 213, wherein the first section 211 is a horizontal section and is located directly below the clamping position, and the third section 213 is adjacent to the board collecting turntable 22 and is used to receive the plywood on the board collecting turntable 22, and the second section 212 is located between the third section 213 and the first section 211, and the second section 212 and the third section 213 are inclined sections, and their heights gradually increase from one end close to the board collecting turntable 22 toward the direction close to the clamping position, so that the plywood is pressed against the board collecting turntable 22 when placed on the support bar 21, thereby preventing it from tipping over.

[0061] Based on the above, the support bar 21 has a three-section structure. When the plywood is located at the third section 213 and the count of the optoelectronic switch 25 reaches the preset quantity, it is necessary to move it to the opening at the position opposite the clamping position on the first section 211, and place the plywood in the fixture 100 from this position. The preset quantity refers to the quantity of plywood that can be held in the fixture 100. Specifically, first move the plywood from the third section 213 to the second section 212. The transfer assembly 23 further includes a hook plate pusher 231 and a hook plate 232. The hook plate 232 is arranged at the output end of the hook plate pusher 231. The hook plate pusher 231 drives the hook plate 232 to push the plywood from the third section 213 onto the second section 212. Specifically, the hook plate 232 is located between two second sections 212. The hook plate pusher 231 drives the hook plate 232 to move along the third section 213, and pushes the plywood on the third section 213 onto the second section 212. Exemplarily, the hook plate pusher 231 uses a cylinder. In order to avoid the hook plate 232 from the third section 213 when the hook plate 232 is not needed to push, a avoidance driving member 233 is further arranged on the frame 1. The hook plate pusher 231 is hinged to the frame 1 and the avoidance driving member 233. Thus, through the drive of the avoidance driving member 233, the hook plate 232 on the output end of the hook plate pusher 231 can be lifted and lowered. Furthermore, when it is necessary to push, it can be lifted to the third section 213, and then the hook plate pusher 231 drives the hook plate 232 to move. When it is not needed to push, the hook plate 232 is lowered below the third section 213 through the drive of the avoidance driving member 233 for avoidance.

[0062] Subsequently, move the plywood from the second section 212 to the first section 211. First, it is necessary to make the second section 212 and the third section 213 collinear. Based on this, as Figure 1 、 Figure 3 and Figure 4As shown, one end of the second section 212 close to the first section 211 is hinged to the frame body 1 through a hinge seat. The transfer assembly 23 further includes a pushing drive member 234. The second section 212 is connected to the output end of the pushing drive member 234. The pushing drive member 234 pushes one end of the second section 212 close to the third section 213 to rotate around the other end, so that the second section 212 is collinear with the first section 211. Subsequently, the plywood is transferred to the first section 211 by the second section 212. Based on this, the transfer assembly 23 includes a horizontal conveying drive member 235. The output end of the horizontal conveying drive member 235 is provided with a conveying frame 236. The conveying frame 236 is located above the supporting strip 21, and a plurality of plywoods can be restricted and enclosed in the conveying frame 236. When the pushing drive member 234 pushes the second section 212 to be collinear with the first section 211, the plywood located on the second section 212 is placed in the conveying frame 236. Subsequently, the horizontal conveying drive member 235 drives the conveying frame 236 to move horizontally, and conveys the plywood from the second section 212 to the first section 211. In the current embodiment, both the pushing drive member 234 and the horizontal conveying drive member 235 adopt air cylinders. Exemplarily, a guiding column 237 is provided on the frame body 1. The guiding column 237 extends along the moving direction of the conveying frame 236, and the conveying frame 236 is slidably arranged on the guiding column 237.

[0063] As Figure 1 and Figure 5 shown, when the plywood moves below the clamp 100 at the bundling and clamping position, it is lifted into the clamp 100 by the lifting assembly 24. Specifically, the lifting assembly 24 includes a lifting drive member 241 and a lifting plate 242 located below the first section 211. The lifting plate 242 is arranged at the output end of the lifting drive member 241, and the lifting plate 242 is located below the clamp 100 at the bundling and clamping position. In this way, the plywood located in the conveying frame 236 can be lifted into the clamp 100 by the lifting and lowering of the lifting drive member 241. Subsequently, the nut on the clamp 100 can be tightened through the bundling and unclamping mechanism 3 to fix it.

[0064] As Figure 1 and Figure 6 shown, when the bundling and unclamping mechanism 3 corresponding to the bundling and clamping position and the unclamping position performs the operations of bundling and unclamping the clamp 100 at this position, the clamp 100 needs to be fixed. Based on this, a resisting block 5 and a resisting drive member 6 are provided on the frame body 1. The resisting block 5 is located between the bundling and clamping position and the unclamping position, and the two resisting drive members 6 are located on both sides of the resisting block 5. The output end of the resisting drive member 6 is provided with a pressing head 7. The resisting drive member 6 drives the pressing head 7 to approach or move away from the resisting block 5, so as to fix or loosen the clamp 100. Exemplarily, the resisting drive member 6 adopts an air cylinder. After the clamp 100 is fixed, the unclamping or bundling operation can be performed through the bundling and unclamping mechanism 3.

[0065] It should be noted here that in the current embodiment, in order to reduce the complexity of operation, when the transfer driving member 41 transfers the empty fixture 100 located at the clamp unloading position to the beam clamping position, the direction conversion is reduced, so that the nuts of the fixture 100 are always on the same side, thereby optimizing the equipment installation space. One of the beam clamping and unloading mechanisms 3 corresponding to the beam clamping position and the beam clamping and unloading mechanism 3 corresponding to the clamp unloading position is arranged on the pressure head 7 to move with the pressure head 7; the other is arranged on the frame body 1, so that the fixture 100 can be placed in the same direction for beam clamping and clamp unloading operations. Of course, it can be understood that the two beam clamping and unloading mechanisms 3 can also be arranged on the frame body 1 or on the pressure head 7 in the same way.

[0066] As Figures 6 to 8 shown, the two beam clamping and unloading mechanisms 3 both include two sets of moving driving members 31 and rotating driving members 32, corresponding to the two nuts of the fixture 100 respectively. Specifically, the two moving driving members 31 of the beam clamping and unloading mechanism 3 at the clamp unloading position are arranged on the side of the clamp unloading position close to the abutting block 5, and a slideway is arranged on the frame body 1, and the slideway extends along the direction close to or away from the fixture 100. A slide table is arranged on the slideway, and the moving driving member 31 at the clamp unloading position is connected to the above-mentioned slide table. A rotatable rotating member 33 is arranged on the slide table, and the rotating driving member 32 corresponding to the clamp unloading position is arranged on the above-mentioned slide table, so as to ensure the stability of the rotating driving member 32 during the process of approaching or leaving the fixture 100. The rotating driving member 32 is connected to the rotating member 33 through a transmission chain or a transmission belt. When the rotating member 33 contacts the nut, the rotating driving member 32 drives the rotating member 33 to rotate, and loosens the nut on the fixture 100 so as to be able to take away the plywood of the fixture 100. Similarly, the beam clamping and unloading mechanism 3 corresponding to the beam clamping position has a mounting frame located on the pressure head 7. The moving driving member 31 is fixed on the above-mentioned mounting frame. A rotating arm is arranged on the mounting frame, and the rotating member 33 rotates on the rotating arm. The output end of the moving driving member 31 is connected to the rotating arm, so as to drive the rotating member 33 on the rotating arm to approach or leave the nut. The rotating driving member 32 is arranged on the mounting frame and is connected to the rotating member 33 through a transmission chain or a transmission belt. When the pressure head 7 abuts against the fixture 100, the rotating member 33 rotates to tighten the nut on the fixture 100. In the current embodiment, the moving driving member 31 is a cylinder, the rotating driving member 32 is a motor, and the rotating member 33 is a rubber wheel, so as to drive the nut to rotate through the friction force between the rubber wheel and the nut contact.

[0067] As Figure 1 and Figure 9As shown, a pushing driving member 8 is further provided on the frame body 1. The clamping position and the unclamping position are both correspondingly provided with the above-mentioned pushing driving member 8. The output end of the pushing driving member 8 is provided with a push head 81. The push head 81 corresponds to the clamp 100 at the clamping position and the unclamping position. Thus, the clamp 100 that has completed clamping at the clamping position is pushed out of the clamping position by the pushing driving member 8; the clamp 100 that needs to be unclamped is pushed into the unclamping position; in the current embodiment, the pushing directions of the pushing driving member 8 at the clamping position and the pushing driving member 8 at the unclamping position are opposite. That is to say, the operator can place the empty clamp 100 or take away the clamp 100 filled with plywood on the same side of the frame body 1. In the current embodiment, the pushing driving member 8 is a cylinder.

[0068] As Figure 1 and Figure 10 shown, a transfer driving member 41 is provided on the frame body 1. The clamping position and the unclamping position are located on the driving path of the transfer driving member 41. Exemplarily, the transfer driving member 41 is a linear driving member. The output end of the transfer driving member 41 is provided with a grasping lifting driving member 42. A clamp fixing member 43 is provided at the output end of the grasping lifting driving member 42, so as to drive the clamp fixing member 43 to approach or move away from the clamp 100 in the height direction, thereby transferring the empty clamp 100 at the unclamping position to the clamping position and reducing manual handling. Specifically, the clamp fixing member 43 includes two relatively arranged hooks 431 and a clamping driving member 432. The clamping driving member 432 is provided at the output end of the lifting driving member. The clamping driving member 432 is provided with two opposite output ends, and each output end is provided with a hook 431. The clamping driving member 432 drives the opposite hooks 431 to approach or move away from each other, so as to hook the two screws on the clamp 100 to be able to move the clamp 100. Exemplarily, the clamping driving member 432 can be a double-headed cylinder. Further, in order to maintain the stability of the fixing points, multiple groups of the clamping driving member 432 and the hooks 431 can be provided.

[0069] As Figure 1 , Figures 10 to 13 shown, the automatic clamping and unloading device for plywood clamps is further provided with a moving-out mechanism 9. The moving-out mechanism 9 is provided at the unclamping position and is configured to move out the plywood in the clamp 100. Specifically, the moving-out mechanism 9 includes a supporting driving member 91 and a bracket 92. The supporting driving member 91 is provided on the frame body 1. The bracket 92 corresponds to the opening at the unclamping position. The supporting driving member 91 can drive the bracket 92 to lift, so as to be able to support the plywood unloaded from the clamp 100 and drive it away from the clamp 100 by the lowering of the bracket 92. That is to say, when the clamp 100 filled with plywood is placed at the unclamping position, the supporting driving member 91 drives the bracket 92 to rise to support the plywood in the clamp 100. When the clamp 100 is unclamped, the supporting driving member 91 drives the bracket 92 to lower to take the plywood away. Exemplarily, the supporting driving member 91 can be a cylinder.

[0070] The removal mechanism 9 further includes a pushing driving member 93 disposed on the frame body 1. A push plate 94 is provided at the output end of the pushing driving member 93. The pushing driving member 8 drives the push plate 94 to move horizontally, thereby pushing the plywood on the bracket 92 away from the bracket 92. In order to enable the plywood to smoothly leave the bracket 92, openings are provided at both ends of the bracket 92 along the horizontal movement direction of the push plate 94.

[0071] In order to receive the plywood separated from the bracket 92, the removal mechanism 9 further includes a turning frame 95 and a turning driving member 96 disposed on the frame body 1. The turning frame 95 is hinged to the frame body 1. The turning driving member 96 drives the turning frame 95 to rotate relative to the frame body 1. A material trough 97 is provided on the turning frame 95. The push plate 94 pushes the plywood on the bracket 92 away from the bracket 92 and gathers it in the material trough 97. Subsequently, the turning driving member 96 drives the material trough 97 to turn to the corresponding external planing rod machine bin for the next step of work.

[0072] The following briefly describes the whole process:

[0073] The operator can place the fixture 100 that has completed the drying of the plywood on the frame body 1. Through the pushing driving member 8 corresponding to the clamp unloading position, it is pushed into the space between the pressing head 7 and the abutting block 5. The supporting driving member 91 drives the bracket 92 to rise to support the plywood in the fixture 100. The abutting driving member 6 corresponding to the clamp unloading position pushes the pressing head 7 so that the pressing head 7 and the abutting block 5 fix the fixture 100. Subsequently, the moving driving member 31 corresponding to the clamp unloading position drives the rotating member 33 to contact the nut on the fixture 100, and then the rotating driving member 32 drives the rotating member 33 to rotate to loosen the nut, realizing clamp unloading. Subsequently, the supporting driving member 91 drives the bracket 92 to descend to take away the plywood, and the pushing driving member 93 pushes the plywood into the material trough 97. During this period, the clamp transfer mechanism 4 moves the unloaded fixture 100 to the clamp bundling position;

[0074] During this period, the receiving plate turntable 22 continuously rotates to transfer the plywood to the third section 213. After the photoelectric switch 25 completes the counting, the avoidance driving member 233 drives the hook plate pusher 231 and the hook plate 232 to the third section 213. Subsequently, the hook plate pusher 231 drives the hook plate 232 to push the plywood onto the second section 212. Then, the pushing driving member 234 drives the second section 212 to rotate, bringing the plywood on the second section 212 into the conveying frame 236. Subsequently, the horizontal conveying driving member 235 drives the conveying frame 236 to move towards the first section 211, moving the plywood below the fixture 100. Then, the lifting driving member 241 drives the lifting plate 242 to rise to send the plywood into the fixture 100. Subsequently, it is stabilized by the pushing driving member 8 and the abutting block 5 at the beam clamping position, and the nut on the fixture 100 is tightened by the beam unloading and clamping mechanism 3 at the beam clamping position to complete the beam clamping operation. Finally, it is pushed out of the beam clamping position by the pushing driving member 8 at the beam clamping position, so that the steps of placing, beam clamping, unloading clamping, and transferring the fixture 100 of the plywood can be automatically realized, improving the efficiency.
