Description

Technical Field

[0001] This utility model relates to the technical field of cardboard processing equipment, specifically to a lateral clamping and positioning device for a destacking machine. Background Technology

[0002] In the paperboard processing industry, destacking machines are a common type of equipment used to separate stacked paper stacks layer by layer for subsequent printing, cutting and other processing steps. However, during the destacking process, when the robotic arm uses suction cups to grip the top layer of paperboard in the stack, it can easily cause slight squeezing or scraping of the remaining paper stack. Alternatively, some of the taller paper stacks may be subject to external interference. Over time, the entire paper stack may shift to the side or tip over, which not only affects the destacking efficiency but may also damage the paper and increase production costs.

[0003] Currently, existing paper stack destacking machines rely mainly on bottom supports or simple side guards for positioning paper stacks, lacking effective lateral clamping mechanisms. When paper stacks are tilted or shifted, they generally move towards the side, which leads to instability during the destacking process and affects normal destacking operations.

[0004] Therefore, it is necessary to provide a new lateral clamping and positioning device for a depalletizer to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a lateral clamping and positioning device for a paper stacker that can reliably prevent paper stacks from tipping over, ensure the stability of the destabilization process, and has a wide range of applications.

[0006] To solve the above-mentioned technical problems, the lateral clamping and positioning device of the paper stacker provided by this utility model includes: a hollow base and a hollow block seat. The bottom of the hollow base is open, and a cross stacking platform is fixedly installed on the top of the hollow block seat. A first stabilizing folding frame is fixedly installed on the opposite outer walls of the hollow block seat, and a second stabilizing folding frame is fixedly installed on the other opposite outer walls of the hollow block seat. The hollow block seat is provided with a transverse clamping mechanism and a longitudinal clamping mechanism; and a moving mechanism is provided on the hollow base.

A first servo motor is fixedly mounted on one of the first stabilizing frames. The output shaft of the first servo motor is fixedly connected to one end of the transverse bidirectional screw. The U-shaped transverse side rail and the first U-shaped sliding rod both pass through the cross stacking platform but do not contact it.

[0008] Furthermore, the longitudinal holding mechanism includes a longitudinally placed bidirectional screw, which is rotatably mounted on the hollow pier. Both ends of the longitudinally placed bidirectional screw pass through two second stabilizing brackets and are rotatably connected to the corresponding second stabilizing brackets.

[0009] Furthermore, buffer pads are fixedly installed on the side of the two U-shaped transverse side guards that are close to each other and on the side of the two U-shaped longitudinal side guards that are close to each other. The buffer pads are made of rubber.

[0010] Furthermore, the first stabilizing folding frame passes between the U-shaped transverse side rail and the first U-shaped slide bar without contacting them, and the second stabilizing folding frame passes between the U-shaped longitudinal side rail and the second U-shaped slide bar without contacting them.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1-6 The lateral clamping and positioning device of the paper stacker includes: a hollow base 1 and a hollow block 2, which are fixedly connected by two bracket plates 19. The bottom of the hollow base 1 is open. A cross stacking platform 3 is fixedly installed on the top of the hollow block 2. Two transverse sliding openings and two longitudinal sliding openings are opened on the cross stacking platform 3. A first stabilizing folding frame 4 is fixedly installed on the opposite outer walls of the hollow block 2. A second stabilizing folding frame 11 is fixedly installed on the other two outer walls of the hollow block 2. The hollow block 2 is provided with a transverse clamping mechanism and a longitudinal clamping mechanism. A moving mechanism is provided on the hollow base 1.

[0026] In this embodiment, the lateral clamping mechanism includes a horizontally positioned bidirectional screw 5 rotatably mounted on the hollow support 2. Both ends of the horizontally positioned bidirectional screw 5 pass through two first stabilizing frames 4 and are rotatably connected to the corresponding first stabilizing frames 4. A first servo motor is fixedly mounted on one of the first stabilizing frames 4, and its output shaft is fixedly connected to one end of the horizontally positioned bidirectional screw 5. Two first adjusting plates 6 are threaded onto the horizontally positioned bidirectional screw 5. A horizontal single bar is fixedly mounted inside each of the two first stabilizing frames 4. The ends of the two horizontal single bars that are close to each other are fixed to the hollow support 2, and the two horizontal single bars pass through the two first adjusting plates 6 and slide along the corresponding first adjusting plates 6. A movable connection is formed to limit the sliding of the first adjusting plate 6; a horizontal sliding plate 7 is fixedly installed on the top of each of the two first adjusting plates 6, and a U-shaped transverse side block 8 is slidably installed on each of the two horizontal sliding plates 7. A first U-shaped sliding rod 9 is fixedly installed on the side of each of the two U-shaped transverse side blocks 8 that is far apart from each other. The two first U-shaped sliding rods 9 pass through the two horizontal sliding plates 7 respectively and are slidably connected to the corresponding horizontal sliding plates 7. A first locking bolt 10 is threaded on one side of each of the two horizontal sliding plates 7. The ends of the two first locking bolts 10 abut against the two U-shaped transverse side blocks 8 respectively. The U-shaped transverse side blocks 8 and the first U-shaped sliding rods 9 pass through the corresponding transverse sliding openings and do not contact the inner wall of the transverse sliding openings.

[0027] In this embodiment, the longitudinal clamping mechanism includes a longitudinally placed bidirectional screw 12 rotatably mounted on the hollow pier base 2. Both ends of the longitudinally placed bidirectional screw 12 pass through two second stabilizing brackets 11 and are rotatably connected to the corresponding second stabilizing brackets 11. A second servo motor is fixedly mounted on one of the second stabilizing brackets 11, and its output shaft is fixedly connected to one end of the longitudinally placed bidirectional screw 12. Two second adjusting plates 13 are threaded onto the longitudinally placed bidirectional screw 12. A longitudinal single bar is fixedly mounted inside each of the two second stabilizing brackets 11. The ends of the two longitudinal single bars that are close to each other are fixed to the hollow pier base 2, and the two longitudinal single bars pass through the two second adjusting plates 13 and are rotatably connected to the corresponding second stabilizing brackets 11. The two adjusting plates 13 are slidably connected; a longitudinal sliding plate 14 is fixedly installed on the top of each of the two second adjusting plates 13, and a U-shaped longitudinal side rail 15 is slidably installed on each of the two longitudinal sliding plates 14. A second U-shaped sliding rod 16 is fixedly installed on the side of each of the two U-shaped longitudinal side rails 15 that is far away from each other. The two second U-shaped sliding rods 16 pass through the two longitudinal sliding plates 14 respectively and are slidably connected to the corresponding longitudinal sliding plates 14. A second locking bolt 17 is threaded on one side of each of the two longitudinal sliding plates 14. The ends of the two second locking bolts 17 abut against the two U-shaped longitudinal side rails 15 respectively. The U-shaped longitudinal side rails 15 and the second U-shaped sliding rods 16 both pass through the corresponding longitudinal sliding openings and do not contact the inner wall of the longitudinal sliding openings.

[0028] In this embodiment, in order to form a clamping protection for the paper stack, a buffer pad 18 made of rubber is fixedly installed on the side where the two U-shaped transverse side bars 8 are close to each other and on the side where the two U-shaped longitudinal side bars 15 are close to each other.

[0029] In this embodiment, the first stabilizing folding frame 4 passes between the U-shaped transverse side rail 8 and the first U-shaped slide bar 9 without contacting them, and the second stabilizing folding frame 11 passes between the U-shaped longitudinal side rail 15 and the second U-shaped slide bar 16 without contacting them. This ensures that the U-shaped transverse side rail 8 and the U-shaped longitudinal side rail 15 can move smoothly without being disturbed by external objects.

[0030] In this embodiment, the moving mechanism includes a mounting panel 20 disposed inside the hollow base 1. Four rollers 21 arranged in a matrix are fixedly mounted on the bottom of the mounting panel 20. An electric push rod 22 is fixedly mounted on the top of the hollow base 1. The output shaft of the electric push rod 22 extends into the hollow base 1 and is fixedly connected to the mounting panel 20. The output shaft of the electric push rod 22 is slidably connected to the top of the hollow base 1. In addition, two columns are slidably mounted on the top of the hollow base 1. The bottom ends of the two columns are fixedly connected to the mounting panel 20. By extending the output shaft of the electric push rod 22, the rollers 21 can contact the ground, and the hollow base 1 can be separated from the ground, thereby facilitating the movement of the device.

[0031] The working principle of the lateral clamping and positioning device for the depalletizer provided by this utility model is as follows:

[0032] In the initial state, the top end faces of both the U-shaped transverse side guard 8 and the U-shaped longitudinal side guard 15 are not higher than the top end face of the cross stacking platform 3.

[0033] Before use, first start the output shaft of the electric push rod 22 to extend, so that the mounting panel 20 with the roller 21 descends, finally lifting the hollow base 1 and making the roller 21 contact the ground. Then move the device to the side of the paper stacker working position.

[0034] When laterally clamping and positioning the paper stack, first place the paper stack on the cross stacking platform 3, and then adjust the height of the U-shaped transverse side rails 8 and U-shaped longitudinal side rails 15 according to the height of the paper stack. During adjustment, first rotate one of the first locking bolts 10 in the reverse direction to separate the first locking bolt 10 from the corresponding U-shaped transverse side rail 8, and then pull the U-shaped transverse side rail 8 upward. After the U-shaped transverse side rail 8 is pulled to the height corresponding to the paper stack, tighten the first locking bolt 10 again. Then adjust the height of the other U-shaped transverse side rail 8 in the same way. After the adjustment is completed, first start the first servo motor in the forward direction. Its output shaft drives the transverse bidirectional screw 5 to rotate. The two first adjusting plates 6 move closer to each other, and the buffer pads 18 on the two U-shaped transverse side rails 8 gradually move towards both sides of the paper stack. After both buffer pads 18 contact the transverse sides of the paper stack, turn off the first servo motor. At this time, the transverse sides of the paper stack are clamped and positioned.

[0035] Then, adjust the height of the two U-shaped longitudinal side blocks 15 in the same way as above. After the adjustment is completed, start the second servo motor in the forward direction. The two second adjustment plates 13 will move closer to each other and finally make the buffer pads 18 on the two U-shaped longitudinal side blocks 15 contact the longitudinal sides of the paper stack. At this time, the clamping and positioning of the transverse and longitudinal sides of the paper stack is completed.

[0036] Then, the paper stack can be picked up layer by layer by the robotic arm of the paper stacker, thus forming the stacking operation.

[0037] Compared with related technologies, the lateral clamping and positioning device for the depalletizer provided by this utility model has the following advantages:

[0038] I. This utility model can achieve a 360-degree clamping and positioning effect on the entire paper stack by setting a horizontal clamping mechanism and a vertical clamping mechanism, thereby completely avoiding the paper stack from tilting, shifting or tilting, so that the unpacking work can be carried out smoothly.
