[0002] The plate stacking device is a mechanical device specially used to stack plates (such as wood, metal plates, plastic plates, etc.) in a certain order and manner. The stacked plates occupy a small area and are more convenient to pack. The plate stacking device can greatly improve production efficiency, reduce manpower requirements, and ensure the stability and safety of the stacking, so it is widely used in the plate packing process.

[0003] Existing plate stacking devices generally use suction cups to suck up the conveyed plates one by one and then stack them, so they generally need to cooperate with lifting, positioning and control systems; however, when the suction cups are used to fix and move the plates, on the one hand, the surface of the plates may be uneven, and on the other hand, if there is dust on the surface of the plates, when the suction cups are moved, the plates are very easy to separate from the suction cups and fall off, so there are great limitations in using suction cups to move and stack plates.

Therefore, the following specific embodiments and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0021] A sheet stacking device for sheet packing, as Figure 1 shown, includes a sheet clamping member and a moving assembly 1. The moving assembly 1 is connected to the sheet clamping member. The sheet clamping member is used to clamp the sheet 6, and the moving assembly 1 is used to drive the sheet 6 to move through the sheet clamping member for stacking; the sheet clamping member includes an opening and closing assembly 3, a connecting rod 4, a clamping plate 5 and a driving assembly 8;

[0022] The opening and closing assembly 3 includes a fixed frame 32, two first telescopic rods 31 and two second telescopic rods 33; as Figure 2As shown, the two telescopic rods 31 are parallel, and the two telescopic rods 33 are parallel. One end of the fixing frame 32 has the telescopic rods 31 inserted on both sides, and the other end of the fixing frame 32 has the telescopic rods 33 inserted on both sides; the driving assembly 8 is connected to the telescopic rods 31 and 33, and the driving assembly 8 is used to drive the telescopic rods 31 and 33 to move away from or close to each other; the cross-section of the fixing frame 32 adopts a structure in the shape of a Chinese character 'Ri', and the driving assembly 8 is arranged inside the fixing frame 32; specifically, the driving assembly 8 includes a second motor 81, a right nut 82, a left nut 83, a lead screw 84, a first transmission rod 85 and a second transmission rod 86; as Figure 3 shown, the lead screw 84 is rotatably connected to the fixing frame 32, and the end of the lead screw 84 is connected to the second motor 81; half of the surface of the lead screw 84 has right-handed threads, and the other half of the surface of the lead screw 84 has left-handed threads; the right-handed threads are connected to the left nut 83, and the left-handed threads are connected to the right nut 82; both sides of the left nut 83 are respectively connected to the telescopic rod 31 through two first transmission rods 85; both sides of the right nut 82 are respectively connected to the telescopic rod 33 through two second transmission rods 86. The driving assembly 8 of the present utility model adopts a structure of a ball screw with right- and left-handed threads; when the second motor 81 drives, it can drive the lead screw 84 to rotate, so that the left nut 83 and the right nut 82 approach or move away from each other, and then drive the telescopic rods 31 and 33 to approach or move away from each other.

[0023] Both between the two telescopic rods 31 and between the two telescopic rods 33 are connected to the clamping plates 5 through connecting rods 4; the driving assembly 8 drives the telescopic rods 31 and 33 to approach or move away from each other, and then drives the two clamping plates 5 to approach or move away from each other, so as to realize the operations of clamping and moving the plate and putting it down.

[0024] The plate stacking device of the present utility model uses the driving assembly to drive the two clamping plates to approach or move away from each other to clamp the plate and put down the plate, so as to realize the stacking of the plates. Compared with the mobile stacking of suction cups, the clamping method of the present utility model is more stable, and even if the plate is not flat enough and has an irregular shape, the plate can still be moved and stacked.

[0025] To improve the firmness of clamping, the two clamping plates 5 are symmetrically arranged, and a first motor 7 is provided on the side of the connecting rod 4; the clamping plate 5 includes an extending portion 51 and a protruding portion 52, the protruding portion 52 is connected to the connecting rod 4, and the bottom end of the protruding portion 52 is rotatably connected to the extending portion 51; the extending portion 51 is connected to the first motor 7, and the first motor 7 is used to drive the extending portion 51 to rotate. The extending portion 51 is used to lift the plate 6, and the protruding portion 52 is used to clamp the plate 6; on the one hand, the plate is ensured not to fall during movement through the dual clamping of lifting by the extending portion 51 and extrusion by the protruding portion 52. On the other hand, when putting down the stacked plates, when the plate 6 to be put down approaches the stacking position, the first motor 7 can be driven to rotate first to make the extending portion 51 rotate and withdraw from the bottom end of the plate 6. At this time, the plate 6 is clamped by the protruding portion 52. After the extending portion 51 is moved away, the plate clamping member continues to move downward until it contacts the stacking position, and then the two clamping plates 5 are separated by the driving assembly 8 to release the plate 6 so that it reaches the predetermined position, effectively avoiding damage to the plate 6 caused by putting down the plate 6 from a certain height.

[0026] To ensure that the two clamping plates 5 move more stably during clamping; the plate clamping member further includes two sets of limiting components 2, and the limiting component 2 includes a limiting sleeve 21 and a moving block 22; the limiting sleeve 21 is fixed to the top end of the fixed frame 32, and moving blocks 22 are inserted and slidably connected to both ends of the limiting sleeve 21; one of the moving blocks 22 is connected to the first telescopic rod 31 through the connecting rod 4, and the other moving block 22 is connected to the second telescopic rod 33 through the connecting rod 4. When the driving assembly 8 drives the first telescopic rod 31 and the second telescopic rod 33 to move, the moving blocks 22 can be driven to move in the limiting sleeve 21.

[0027] To move the entire plate clamping member to stack the plates 6; the moving assembly 1 includes a pneumatic slide rail 11, a pneumatic slider 12, an electric telescopic rod 13, and a support frame 14; the pneumatic slide rail 11 is provided on the side of the support frame 14, and the pneumatic slide rail 11 is slidably connected to the pneumatic slider 12; the side of the pneumatic slider 12 is connected to the electric telescopic rod 13, and the output end of the electric telescopic rod 13 is connected to the fixed frame 32.

[0028] When the utility model is in use, the plate 6 to be stacked is conveyed to a temporary storage table with a width smaller than that of the plate 6. First, the moving assembly 1 is used to move the entire plate clamping member to the top of the plate 6 that needs to be stacked and moved. Specifically, the clamping plates 5 are located on both sides of the plate 6, and the outer extension portion 51 is located at the bottom of the plate 6. The movement of the plate clamping member is specifically realized by using the pneumatic slider 12 to move on the pneumatic slide rail 11 to achieve the horizontal movement of the plate clamping member, and the electric telescopic rod 13 is used to drive the plate clamping member to move in the vertical direction. After the plate clamping member moves to this position, the driving motor two 81 is driven. When the motor two 81 is driven, it can drive the lead screw 84 to rotate, so that the left nut 83 and the right nut 82 approach each other, and then drive the two clamping plates 5 to approach through the telescopic rod one 31 and the telescopic rod two 33, and clamp the plate 6 with the two clamping plates 5 as shown in Figure 1 ; At this time, the plate 6 is clamped through the convex portion 52, and the outer extension portion 51 is located at the bottom of the plate 6 for lifting, protecting the plate 6 to prevent it from falling; Then, after moving the plate 6 to the stacking position by using the moving assembly 1, the clamped plate 6 is brought close to the stacking position, and then the motor one 7 is started, so that the motor one 7 drives the two outer extension portions 51 to rotate until the outer extension portions 51 leave from the bottom of the plate 6. At this time, the plate 6 is squeezed and clamped by the two convex portions 52, and then the plate clamping member is continuously lowered until the plate 6 contacts the stacking position, and then the motor two 81 is started to separate the two clamping plates 5, so that the plate 6 is stacked to the stacking position.

[0029] The utility model uses a positive and negative thread ball screw to drive the two clamping plates to approach or separate to clamp the plate, and cooperates with the moving assembly to realize the movement and stacking of the plate. Compared with the moving and stacking of the suction cup, the clamping method of the utility model is more stable, and even if the plate is not flat and has an irregular shape, the movement and stacking of the plate can still be carried out.

[0030] The utility model is provided with a clamping plate with a special structure. The clamping plate with a special structure can ensure that the plate will not fall during movement through double clamping of lifting by the outer extension portion and extrusion by the convex portion when the plate is conveyed and moved. After the plate is about to reach the stacking position, first, the outer extension portion rotates away and the plate is fixed by extrusion through the convex portion. After the plate reaches the stacking position, the clamping plate is separated to ensure that the plate is stably placed in the appropriate position without damage to the plate and the placement is more stable.
