Description

Technical Field

[0001] The invention relates to the technical field of automatic labeling, and in particular to a sheet material stripping device. Background Art

[0002] In the manufacturing industry, the labeling process of sticking labels or films is a very common process. Generally, labels and films are usually set on strip-shaped base paper or sheet-shaped base paper. Therefore, when labeling, it is necessary to first remove the label from the base paper and then move it to the labeling station for labeling.

[0003] At present, existing enterprises usually use an automatic turntable to pull the base paper, and then use a robot + suction cup structure to remove the label from the base paper to carry out labeling. However, when removing the label or film, since the label or film is stuck between the base paper and has a certain adhesive force, a large suction force is required to remove it smoothly when the suction cup is used. This may cause wrinkles on the label or film, and also cause the base paper to be pulled, resulting in adverse consequences, which has a great impact on the subsequent labeling work and has limitations.

When the front end of the bottom paper is perpendicular to the right side of the unloading long board 1, the receiving cylinder 32 is driven so that the receiving platform 33 presses the bottom paper against the side of the unloading long board 1. Then, in the process of pulling down the bottom paper, the standard parts on the upper surface will be peeled off and moved to the receiving platform 33; in addition, a number of through slots are provided on the receiving platform 33, and standard part sensors are provided in the through slots, which can sense whether there are standard parts on the receiving platform 33, so as to feed back the information to the external standard part taking robot to take away the standard parts, making the overall work smoother and more intelligent.

[0027] like Figure 3As shown, in this embodiment, the bottom paper pulling-down mechanism 2 includes a mounting vertical plate 21, a driving motor 22, a lifting platform 23 and two groups of paper clamping assemblies 24. The lifting platform 23 is slidably arranged on the mounting vertical plate 21. The driving motor 22 is arranged on the mounting vertical plate 21 and is transmission-connected to the lifting platform 23. The two groups of paper clamping assemblies 24 are arranged on both sides of the lifting platform 23 and cooperate with the unloading long board 1. In the above, the bottom paper pulling-down mechanism 2 includes a mounting vertical plate 21, a driving motor 22, a lifting platform 23 and two sets of paper clamping components 24, the driving motor 22 is located on the left side of the mounting vertical plate 21, the lifting platform 23 is located on the right side of the mounting side plate, two vertical long guide rails are arranged on the right side of the mounting vertical plate 21, the lifting platform 23 slides with the two long guide rails through a slider to achieve a sliding effect, the upper and lower ends of the right side of the mounting vertical plate 21 are provided with transmission wheels, the two transmission wheels are connected by transmission belts, the lifting platform 23 is fixedly connected to the transmission belt, the output shaft of the driving motor 22 passes through the mounting vertical plate 21 and is connected to the transmission wheel at the lower end to achieve the connection with the lifting platform 23 The drive motor 22 is used to drive the lifting platform 23 to slide up and down on the mounting vertical plate 21, thereby driving the two groups of paper clamping assemblies 24 to move up and down, and the two groups of paper clamping assemblies 24 are used to clamp the bottom paper placed on the unloading long board 1; during operation, a robot or a person places the sheet of bottom paper on the unloading long board 1, and then the drive motor 22 drives the two groups of paper clamping assemblies 24 to move up, and then the two groups of paper clamping assemblies 24 clamp the two sides of the right end of the bottom paper, and then the drive motor 22 reverses and drives the bottom paper to move down. During this period, the receiving cylinder 32 is driven in time to make the receiving platform 33 dock with the unloading long board 1, so that the standard is peeled off from the bottom paper and moved to the receiving platform 33.

[0028] like Figure 5 , Figure 6As shown, in this embodiment, the paper clamping assembly 24 includes a paper clamping bottom plate 241, a paper clamping cylinder 242, a limiting push block 243, a positioning push block 244, an upper paper clamping block 245, a lower paper clamping block 246, and two limiting side plates 247. The lower paper clamping block 246 and the paper clamping cylinder 242 are respectively arranged at the left and right ends of the paper clamping bottom plate 241. The two limiting side plates 247 are respectively arranged at the front and rear sides of the paper clamping bottom plate 241. The limiting push block 243 is slidably arranged on the paper clamping bottom plate 241. A first pin shaft 248 is arranged at the left end of the positioning push block 244. The two ends of the first pin shaft 248 are respectively matched with the bent waist-shaped holes 249 formed in the two limiting side plates 247. A hinged groove 250 is formed at the right end of the positioning push block 244. The left end of the limiting push block 243 is embedded in the hinged groove 250 and is provided with a straight waist-shaped hole 251. A second pin shaft 252 passing through the straight waist-shaped hole 251 is arranged in the hinged groove 250. A compression spring 253 is arranged in the hinged groove 250. The two ends of the compression spring 253 are matched with the positioning push block 244 and the limiting push block 243. The upper paper clamping block 245 is arranged on the left side of the positioning push block 244 and is matched with the lower paper clamping block 246.Among the above, the paper clamping assembly 24 includes a paper clamping bottom plate 241, a paper clamping cylinder 242, a limiting push block 243, a clamping position push block 244, an upper paper clamping block 245, a lower paper clamping block 246 and two limiting side plates 247. The paper clamping cylinder 242 is used to drive the limiting push block 243 and the clamping position push block 244 to move in cooperation, so as to drive whether the upper paper clamping block 245 and the lower paper clamping block 246 are clamped. The limiting push block 243 is slidably arranged left and right on the paper clamping bottom plate 241 and is located among the lower paper clamping block 246, the paper clamping cylinder 242 and the two limiting side plates 247. The clamping position push block 244 is located on the left side of the limiting push block 243. The lower left end of the clamping position push block 244 is hinged and matched with the bent waist-shaped holes 249 on the two limiting side plates 247 through a first pin shaft 248. A hinged groove 250 is formed at the right end of the clamping position push block 244, and the clamping position push block 244 is hinged to the straight waist-shaped hole 251 formed at the left end of the limiting push block 243 through a second pin shaft 252. The compression spring 253 is arranged in the hinged groove 250 and forms a supporting force between the limiting push block 243 and the clamping position push block 244. The upper paper clamping block 245 and the lower paper clamping block 246 are respectively arranged on the left sides of the clamping position push block 244 and the paper clamping bottom plate 241, so as to realize the clamping or loosening action. By default, the paper clamping assembly 24 is in a loosened state. During operation, the paper clamping cylinder 242 is driven to extend, so as to push the limiting push block 243 to slide leftward. The compression spring 253 presses on the clamping position push block 244, so that the second pin shaft 252 moves obliquely upward along the straight waist-shaped hole 251, making the clamping position push block 244 change from an inclined state to a parallel state. At the same time, the first pin shaft 248 moves downward and leftward along the bent waist-shaped hole 249, so as to change the state of the originally obliquely opened upper paper clamping block 245, making it parallel to the lower paper clamping block 246 and cooperate to clamp. When the upper paper clamping block 245 and the lower paper clamping block 246 are clamped, since the second pin shaft 252 is already at the uppermost end of the straight waist-shaped hole 251, and at the same time the telescopic spring also exerts a supporting force on the clamping position push block 244, self-locking is formed. Therefore, when an external force is used to lift the upper paper clamping block 245 upward, the upper paper clamping block 245 can remain locked, so as to ensure the clamping of the bottom paper during the paper pulling process. As can be seen from the above, the paper clamping assembly 24 has a self-locking function and can effectively clamp the bottom paper. Even if the paper clamping cylinder 242 fails due to air cut-off during operation, it can still maintain the clamping of the bottom paper, thus ensuring the smooth progress of the entire peeling work.

[0029] As Figure 3As shown, in this embodiment, a mounting slide plate 25 is slidably arranged left and right on the lifting table 23. Synchronous cylinders 26 are arranged on both sides of the lifting table 23. The two synchronous cylinders 26 act synchronously and their output ends are connected to the mounting slide plate 25. Two groups of paper clamping assemblies 24 are arranged on both sides of the mounting slide plate 25. The mounting slide plate 25 is slidably arranged on the upper end of the lifting table 23 through a slide rail and a slider. The two synchronous air cylinders are respectively located on both sides of the lifting table 23 and their output ends are both connected to the mounting slide plate 25 and the two synchronous air cylinders are synchronously driven. The two groups of paper clamping assemblies 24 are located on both sides of the mounting slide plate 25 and thus move following the movement of the mounting slide plate 25. During operation, after the two groups of paper clamping assemblies 24 clamp the base paper, they are pulled downward under the action of the drive motor 22. During the pulling process, the two synchronous air cylinders drive the mounting slide plate 25 to move a short distance towards the side of the feeding long plate 1, so that the two groups of paper clamping assemblies 24 drive the base paper to move accordingly. The part of the base paper located on the right side of the feeding long plate 1 changes from a vertical state to an inclined state, forming a negative angle. In this way, the standard parts can be better peeled off from the base paper and enter the receiving table 33. As can be seen from the above, through the above structure, the effect of peeling the standard parts from the base paper can be greatly improved, and the success rate of the peeling work is increased.

[0030] As Figure 7As shown, in this embodiment, the sheet stripping device also includes a discharge rack 4, the discharge long board 1 is arranged on the discharge rack 4, the bottom paper pull-down mechanism 2 and the sheet receiving mechanism 3 are both arranged on the right side of the discharge rack 4, and a bottom paper recovery mechanism 5 is arranged on the left side of the discharge rack 4, the bottom paper recovery mechanism 5 includes a matching paper feeding module 51 and a paper receiving module 52, the paper receiving module 52 includes a fixed frame 521, a lifting cylinder 522, a lifting frame 523, a paper receiving motor 524 and a paper receiving roller 525, the fixed frame 521 is arranged on the discharge rack 4, the lifting cylinder 522 is arranged on the fixed frame 521, the lifting frame 523 is arranged at the output end of the lifting cylinder 522, the paper receiving roller 525 is rotatably arranged on the lifting frame 523 and matched with the discharge long board 1, and the paper receiving motor 524 is arranged on the lifting frame 523 and is transmission-connected with the paper receiving roller 525.

When collecting paper, the paper feeding module 51 moves the bottom paper to the working position of the paper feeding module 51, and the lifting device drives the lifting frame 523 to move down, so that the paper receiving roller 525 is against the bottom paper, and then the paper receiving motor 524 is driven, and the paper receiving roller 525 rotates to drive the bottom paper to move toward the left end of the discharge long board 1, so as to realize the feeding of the bottom paper. It can be seen from the above that the bottom paper recycling mechanism 5 can realize the recycling of sheet bottom paper through the cooperation of the paper feeding module 51 and the paper feeding module 51, which is suitable for the recycling of sheet bottom paper, can operate continuously and efficiently. In addition, in the present embodiment, the number of the paper receiving rollers 525 is two, and the two paper receiving rollers 525 are arranged in parallel at the lower end of the lifting frame 523. The outer side of the lifting frame 523 is rotatably provided with two synchronous large gears, and the two synchronous large gears are provided with synchronous flat belts. The paper receiving motor 524 is transmission-connected to one of the synchronous large gears, and the outer side of the lifting frame 523 is rotatably provided with two synchronous small gears, and the two synchronous small gears are respectively meshed with the two synchronous large gears and connected to the corresponding paper receiving rollers 525.There are two paper receiving drums 525 in total, which are arranged one in front of the other along the direction of the feeding long board 1 within the lifting frame 523. The two synchronous large gears are connected by the synchronous flat belt, and the paper receiving motor 524 is connected to one of the synchronous large gears so as to drive the two synchronous large gears to rotate synchronously. The same end of the central axes of the two paper receiving drums 525 penetrates out of the lifting frame, and the two synchronous small gears are respectively arranged on the two central axes. Therefore, the rotation of the two synchronous small gears is consistent with the rotation of the paper receiving drums 525, and the two synchronous small gears are respectively meshed with the corresponding synchronous large gears. Therefore, when the paper receiving motor 524 is driven, the two paper receiving drums 525 can rotate simultaneously. When recycling the base paper, the base paper with a longer length can be recycled to ensure the successful delivery of the base paper.

Then the parallel cylinder 62 is driven, and the two adjusting plates 63 move relatively closer, so that both sides of the base paper are respectively carried by the two adjusting steps 64. Then the parallel cylinder 62 continues to be driven, so that both sides of the base paper are flush with the inner side surfaces of the adjusting plates 63, thus achieving the position adjustment function. As can be seen from the above, through the base paper adjusting mechanism 6, positioning work can be carried out before the standard part stripping work, so that the base paper can be driven by the base paper pulling-down mechanism 2 in an ideal state, so as to better carry out the stripping work.

The blowing paper fan 7 is used to cooperate with the paper receiving module 52 to prevent the waste base paper from hanging on the feeding long plate 1 without falling to the designated position, ensuring the complete recovery of the waste base paper. The two base paper sensors are both used to sense whether there is base paper on the feeding long plate 1. Among them, the left base paper sensor is used to sense whether there is waste base paper that has not fallen, so as to control the blowing paper fan 7 to work. The right base paper sensor is used to sense whether there is base paper on the feeding long plate 1, so as to feed back the information to the base paper pulling-down mechanism 2 or the base paper recycling mechanism 5, and then corresponding work is carried out.

[0034] As Figure 4As shown, in this embodiment, a vertical cylinder 34 is provided on the receiving seat 31, and the receiving cylinder 32 is arranged at the output end of the vertical cylinder 34. The vertical cylinder 34 is used to drive the receiving cylinder 32 to move up and down, so as to realize the height adjustment of the receiving table 33, so as to better cooperate with the feeding long plate 1 and enhance the adaptability.

[0035] As Figure 4 shown, in this embodiment, a serrated pattern 35 is provided on the upper end surface of the side of the receiving seat 31 close to the feeding long plate 1, and a Teflon coating is applied on the serrated pattern 35. The provision of the serrated pattern 35 on the upper end surface of the receiving seat 31 can reduce the adhesion of the standard parts to the receiving seat 31, so as to better pick up the standard parts, and through the Teflon coating, the adhesion effect of the standard parts can be further reduced.

[0036] The working principle of the present invention is as follows: The sheet-shaped base paper is placed on the feeding long plate 1 manually or by a manipulator. Subsequently, the base paper adjustment mechanism 6 operates to adjust the position of the base paper. The base paper pulling-down mechanism 2 clamps both sides of the right end of the base paper and drives the base paper to be pulled down. At the same time, the sheet material receiving mechanism 3 operates to dock with the feeding long plate 1. The paper feeding module 51 of the base paper recycling mechanism 5 clamps both sides of the left end of the base paper, so as to form a pulling force on the base paper, so that the base paper can closely adhere to the feeding long plate 1. During the pulling-down process of the base paper, since the base paper changes from a parallel state to a vertical state and then cooperates with the sheet material receiving mechanism 3, the standard parts on the base paper will be peeled off and moved onto the sheet material receiving mechanism 3, and then taken away by the labeling manipulator for labeling; when all the standard parts on the base paper are peeled off, the base paper pulling-down mechanism 2 releases the base paper and resets. The paper feeding module 51 pulls the base paper back and sends it to the working position of the paper receiving module 52, and the paper receiving module 52 recycles the waste base paper, and one peeling operation is completed; repeating the above actions can achieve cyclic operation.

[0037] Although the embodiments of the present invention are described with actual solutions, they do not constitute a limitation on the meaning of the present invention. For those skilled in the art, the modifications of its implementation solutions according to this specification and the combinations with other solutions are obvious.
