[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0017] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0018] Combination Figure 1-4 As shown, the unloading and stacking device includes two frames arranged adjacent to each other on the left and right, wherein the left frame is marked as 1 and the right frame is marked as 2, and a feeding table 3 is provided in each of the frames, an upper and lower conveying mechanism is provided in the left frame 1, and an unloading and stacking mechanism is provided in the right frame, and a clamping mechanism that can move laterally is provided on the top of the two frames, and the unloading and stacking mechanism includes a pair of slide bars 4 rotatably installed on both sides of the right frame respectively, and a slide 5 is provided on the same pair of slide bars 4, and a group of support blocks 6 are formed on the top of the slide 5, and a short block 7 is provided on the outer side of the support block 6, and a bearing block 8 is rotatably provided on the side wall of the short block 7 through a torsion spring (not shown in the figure), and the bearing block is located directly above the support block, and a stacking screw rod 9 is also provided between the same pair of slide bars, and a stacking screw rod sleeve 10 is sleeved on the stacking screw rod and the stacking screw rod sleeve is connected to the back of the slide 5, and a driving motor 11 for driving the stacking screw rod to rotate is also provided on the right frame 2, and an unloading mechanism is also provided in the right frame 2 and below the slide 5.
[0019] In this structure, both the left and right racks are provided with feeding tables. When the cardboard production is completed, the cardboard is dropped onto the left feeding table one by one and in an orderly manner. The cardboard is transported to the loading position by the left feeding table, and then the upper and lower conveying mechanisms hold the cardboard and move it upward. After it moves into position, it is clamped by the clamping mechanism and slides horizontally to transfer the cardboard to the top of the right rack. After sliding into position, the clamping mechanism releases the cardboard and resets to wait for the next cardboard to be transferred. At this time, the two sides of the cardboard fall on the two groups of bearing blocks respectively, and then the slide moves downward by one station, waiting for the next cardboard to be dropped and stacked on the current cardboard.
[0020] In actual working conditions, if the slide needs to move up and down, the drive motor will drive the stacking screw to rotate, and the stacking screw sleeve will move along the height direction of the stacking screw, and then the slide and the stacking screw sleeve will move synchronously.
[0021] In the embodiment, in the non-working state, the top of the bearing block is tilted upward and toward the right frame. A small distance from the top of the bearing block is located inside the right frame. After the clamping mechanism releases the cardboard, the two sides of the cardboard fall on the two groups of bearing blocks respectively. At this time, the bearing block rotates toward the right frame under the gravity of the cardboard until the inner side of the bearing block contacts the support block, and the support block plays a role in supporting the bearing block.
[0022] The unloading mechanism includes a transverse plate 12 installed on the right frame 2, a pair of guide rods 13 are provided between the transverse plate 12 and the bottom of the right frame, a guide sleeve 14 is sleeved on the guide rod 13, a mounting plate 15 is provided between the two guide sleeves 14, and unloading plates 16 are provided at both ends of the mounting plate 15. A unloading cylinder 17 is provided downwardly on the transverse plate 12, and a driving shaft of the unloading cylinder 17 is connected to the mounting plate 15.
[0023] When the cardboards on the two sets of bearing blocks are stacked, the slide is located below the right frame. At this time, the unloading cylinder drives the mounting plate to move upward along the guide rod for a short distance, and the two unloading plates move upward at the same time and lift up the stacked cardboards. When the stacked cardboards are separated from the bearing blocks, the bearing blocks rotate backward to their original state under the action of the torsion springs and form an avoidance. Finally, the two unloading plates move downward until the stacked cardboards fall on the right feeding table and transport the stacked cardboards to the next station.
[0024] In this device, the upper and lower conveying mechanism includes a pair of guide rods 18 installed in the left frame 1 and at the front end, and guide sleeves 19 are provided on the guide rods. A fixed plate 20 is provided on the two guide sleeves 19, and a loading plate 21 is provided at both ends of the fixed plate. A conveying screw 22 is provided between the guide rods 18, and a conveying screw sleeve 23 is sleeved on the conveying screw 22 and the conveying screw sleeve is connected to the back of the fixed plate 20. A loading motor 24 for driving the conveying screw to rotate is provided in the left frame 1.
[0025] When the cardboard is transported to the loading position by the feeding table, the two loading plates are located below the cardboard. The loading motor drives the conveying screw to rotate. At this time, the conveying screw sleeve moves upward along the height direction of the conveying screw, and the two fixed plates move upward. The loading plates hold the cardboard and move upward. After moving to the clamping position, the loading motor stops rotating, and the cardboard is clamped by the clamping mechanism.
[0026] As a preferred structure, bilateral linear motor modules 25 are respectively provided on the top and front and rear sides of the two frames, and a transfer block 26 is provided on a pair of moving ends of the bilateral linear motor modules, the clamping mechanism includes a vertical frame 27 jointly installed on the transfer block, the vertical frame is provided with a lifting cylinder 28 facing downward, and a clamping frame 29 is provided on the driving shaft of the lifting cylinder, the bottom surface of the clamping frame and the front and rear ends are respectively provided with short grooves and long grooves 30, a pair of adjusting rods 31 are provided on the bottom surface of the clamping frame corresponding to the long grooves, an adjusting frame 32 is slidably provided on the adjusting rods, clamping cylinders 33 are respectively provided in the short grooves and on the adjusting frame 32, a clamping block 34 is provided on the driving shaft of the clamping cylinder, an adjusting linear motor module 35 is provided on the top surface of the clamping frame downward, and the moving end of the adjusting linear motor module is connected to the adjusting frame 32.
[0027] When the cardboard rises to the clamping position, the lifting cylinder drives the clamping frame to move down one station. The two clamping blocks are located at the front and rear ends of the cardboard, and then the two clamping cylinders simultaneously drive the corresponding clamping blocks to move inward until the cardboard is clamped. Then the lifting cylinder drives the clamping frame to move upward, and the moving ends of the two pairs of bilateral linear motor modules move toward the right frame at the same time. At this time, the entire clamping mechanism moves synchronously. After moving into place, the two clamping blocks release the cardboard, and the two sides of the cardboard fall on the two groups of bearing blocks for unloading and stacking.
[0028] In this structure, the position of the rear clamp block is adjustable to accommodate cardboards of different lengths. When the position of the rear clamp block needs to be adjusted, the linear motor module is adjusted to drive the adjustment frame to move forward and backward, and the clamping cylinder on the adjustment frame moves synchronously to adjust the position of the rear clamp block. When the mobile end of the linear motor module is adjusted to drive the adjustment frame to move forward and backward, the adjustment frame slides on the adjustment rod, making the entire adjustment process more stable.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
