Description

Technical Field

[0001] The utility model relates to the technical field of cigarette carton processing, in particular to a paper rubbing device, a feeding device and a cigarette carton packaging supply line. Background Art

[0002] The strip carton paper is a material for producing cigarette cartons. When it is transported and stored, multiple strip carton papers are usually stacked and then packed with a wrapping tape such as kraft paper to form a material stack. When loading the material stack onto a packing machine, the wrapping tape needs to be removed.

[0003] In the prior art, when the wrapping tape is wound around the material stack, the wrapping tape usually adheres to the outer surface of the material stack, and the gap between it and the material stack is small. When removing the wrapping tape, the wrapping tape is manually rubbed up to make a local bulge of the wrapping tape, so as to facilitate cutting the wrapping tape with a cutting knife. Although manually rubbing up the bulging tape can effectively complete the cutting of the wrapping tape, when loading a large number of material stacks, this cutting method is not only time-consuming and laborious, but also inefficient.

[0004] Therefore, there is an urgent need for a paper rubbing device, a feeding device and a cigarette carton packaging supply line to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a paper rubbing device, a feeding device and a cigarette carton packaging supply line, which solve the problem that when the wrapping tape is manually rubbed up to make a bulge during cutting in the prior art, the removal of the wrapping tape is not only time-consuming and laborious, but also inefficient when loading a large number of material stacks.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] In a first aspect, the utility model provides a paper rubbing device, which includes:

[0008] A base;

[0009] A bearing platform, which is arranged on the base and used for bearing the material stack;

[0010] An extrusion plate, which is slidably connected to the base and can abut against the wrapping tape of the material stack;

[0011] A first driving member, which is connected to the extrusion plate to drive the extrusion plate to approach or move away from the material stack;

[0012] A second driving member, which is connected to the first driving member to drive the first driving member and the extrusion plate to rise when the extrusion plate extrudes the wrapping tape of the material stack, so that a bulging part to be cut of the wrapping tape of the material stack is formed.

[0013] Optionally, the paper rubbing device further includes:

[0014] A third driving member, connected to the second driving member to drive the second driving member to rise, so that the pressing plate can correspond to the stack of materials.

[0015] Optionally, the stroke of the third driving member is greater than the stroke of the second driving member.

[0016] Optionally, the paper rubbing device further includes:

[0017] An adsorption disc, penetrating through the pressing plate for adsorbing the cut wrapping tape.

[0018] Optionally, the paper rubbing device further includes:

[0019] A fourth driving member, connected to the adsorption disc to drive the adsorption disc to approach or move away from the stack of materials.

[0020] Optionally, the paper rubbing device further includes:

[0021] A first mounting plate, on which the first driving member is arranged;

[0022] A pulling plate, slidably connected to the first mounting plate, at least part of the pulling plate extending out of the first mounting plate and fixedly connected to the pressing plate.

[0023] Optionally, the paper rubbing device further includes:

[0024] A second mounting plate, on which the second driving member is arranged;

[0025] A guide post, one end of which is fixedly connected to the first mounting plate, and the other end passes through the second mounting plate and is slidably connected to the second mounting plate.

[0026] Optionally, the paper rubbing device further includes:

[0027] A protective cover, covering the first driving member and the second driving member.

[0028] In a second aspect, the present invention provides a feeding device, including:

[0029] The paper rubbing device according to any one of the first aspect, for rubbing the wrapping tape of the stack of materials to form a bulge;

[0030] A cutting and handling device, for transporting the stack of materials to the paper rubbing device and capable of cutting the bulge formed by the wrapping tape of the stack of materials;

[0031] A conveying device, for sending the stack of materials after cutting the wrapping tape to the processing equipment.

[0032] In a third aspect, the present invention provides a cigarette carton packaging supply line, including:

[0033] The feeding device described in the second aspect is used to sequentially cut the wrapping belts of multiple stacks of materials and then send them to a packaging machine for processing.

[0034] Advantages of the present utility model:

[0035] In the first aspect, when the paper rubbing device is in use, a stack of materials is first transported onto the carrying platform. After centering and fixing the stack of materials on the carrying platform, the first driving member drives the pressing plate to approach the stack of materials, so that the pressing plate abuts against the wrapping belt of the stack of materials. Then, the second driving member acts to push the first driving member and the pressing plate to rise, and the pressing plate rubs the wrapping belt upward, causing the wrapping belt to form a bulge. In this embodiment, the wrapping belt is kraft paper to facilitate cutting the wrapping belt. Thus, when this paper rubbing device is applied to the full-automatic feeding of cigarette packaging strip boxes, the strip box stack, as the stack of materials, can use the pressing plate to abut against the wrapping belt to ensure sufficient surface contact between the two, so that the friction between the pressing plate and the wrapping belt is sufficient. Then, when the second driving member acts, the pressing plate can smoothly rub up the wrapping belt to form a bulge, which is convenient for the subsequent cutter structure to quickly cut the bulge, so that the paper rubbing process no longer needs to be completed manually, making the cutting process time-saving and labor-saving, and effectively improving the cutting efficiency.

[0036] In the second aspect, when the feeding device is in use, it can automatically rub up a bulge on the wrapping belt by using the paper rubbing device, so that the cutting and handling device can smoothly cut the wrapping belt. Then, a large number of stacks of materials can be fully automated in the processes of handling, paper rubbing, cutting, paper extraction, and conveying, effectively reducing the degree of manual participation and being beneficial to improving the feeding efficiency.

[0037] In the third aspect, when the cigarette strip box packaging supply line is in use, the feeding device can automatically and sequentially transport the stacks of materials to the carrying platform of the paper rubbing device in an orderly manner, cut the wrapping belts of the stacks of materials, and then send the materials to the packaging machine to complete the feeding. The entire feeding process can be fully automated, effectively improving the degree of automation of feeding, reducing the degree of manual participation, and at the same time, it can also effectively reduce the possibility of the stacks of materials being scattered, improving the stability and continuity of the feeding process.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0063] The embodiment of the present utility model discloses a paper feeding device, a feeding device, and a cigarette carton packaging supply line.

[0064] Refer to Figures 1 to 4 , the paper feeding device includes a base 1, a bearing table 2, a pressing plate 3, a first driving member 4, and a second driving member 5. The bearing table 2 is arranged on the base 1 and is used for bearing a material stack 6; the pressing plate 3 is slidably connected to the base 1 and can abut against the wrapping belt 61 of the material stack 6; the first driving member 4 is connected to the pressing plate 3 to drive the pressing plate 3 to approach or depart from the material stack 6; the second driving member 5 is connected to the first driving member 4 to drive the first driving member 4 and the pressing plate 3 to rise when the pressing plate 3 presses the wrapping belt 61 of the material stack 6, so that the wrapping belt 61 of the material stack 6 forms a bulging to be cut.

[0065] Specifically, the base 1 is in the shape of a cube. Foot supports 11 can be provided at the bottom of the base 1 to fix the base 1 on the ground surface. Universal wheels 12 can also be provided at the positions of the base 1 corresponding to the foot supports 11, so that the base 1 can be moved to conveniently adjust the position of the base 1. A lifting driving member 21, such as a cylinder, is provided on the top wall of the base 1, and it can extend and retract the piston rod in the vertical direction. The bearing platform 2 is fixed at the end of the piston rod. The bearing platform 2 can be in the shape of a cube, specifically a cuboid, and in the horizontal projection plane, the cross-sectional area of the bearing platform 2 is smaller than the cross-sectional area of the material, so that after the material stack 6 is placed on the bearing platform 2, the four side walls of the material stack 6 can protrude from the bearing platform 2.

[0066] A sizing device 7 can be provided on the base 1. The sizing device 7 can abut against the material stack 6 from two opposite side walls of the material stack 6 to size the material stack 6, so that the material stack 6 is centered and fixed on the bearing platform 2. The pressing plate 3 can abut against the other side walls of the material stack 6 under the action of the first driving member 4, so as to further size the material stack 6. At the same time, under the action of the second driving member 5, the wrapping belt 61 is extruded upward to form a bulge, and the cutting knife structure can cut off the wrapping belt 61 by cutting off the bulge.

[0067] The side surface of the pressing plate 3 facing the material stack 6 can be divided into two parts. The part corresponding to the wrapping belt 61 can be provided with a rough layer to increase the friction force generated when the pressing plate 3 abuts against the wrapping belt 61. A smooth film can be provided around the rough layer so that the pressing plate 3 will not wear the material when abutting against the material stack 6. The size of the rough layer can be smaller than the size of the wrapping belt 61 to ensure that the wrapping belt 61 can completely cover the rough layer and also prevent the rough layer from contacting the side wall of the material stack 6.

[0068] Both the first driving member 4 and the second driving member 5 can adopt cylinders to make the movement control of the pressing plate 3 simple and reliable. The first driving member 4 and the second driving member 5 can also be realized by a motor cooperating with a corresponding transmission structure to further improve the precision of the movement control of the pressing plate 3. The present utility model does not limit the specific types of the first driving member 4 and the second driving member 5.

[0069] When the paper feeding device is in use, the material stack 6 is first transported onto the bearing table 2. After the material stack 6 is centered and fixed on the bearing table 2, the first driving member 4 drives the pressing plate 3 to approach the material stack 6, so that the pressing plate 3 presses against the wrapping belt 61 of the material stack 6. Then, the second driving member 5 operates to push the first driving member 4 and the pressing plate 3 to rise. The pressing plate 3 rubs the wrapping belt 61 upward, causing the wrapping belt 61 to form a bulge. In this embodiment, the wrapping belt 61 is kraft paper to facilitate cutting the wrapping belt 61. Thus, when this paper feeding device is applied to the full-automatic feeding of cigarette packaging strip boxes, with the strip box stack as the material stack 6, the pressing plate 3 can press against the wrapping belt 61 to ensure sufficient surface contact between the two, so that the friction between the pressing plate 3 and the wrapping belt 61 is sufficient. Then, when the second driving member 5 operates, the pressing plate 3 can smoothly rub up the wrapping belt 61 to form a bulge, facilitating the subsequent cutter structure to quickly cut the bulge, so that the paper rubbing process no longer requires manual operation, making the cutting process time-saving and labor-saving, and effectively improving the cutting efficiency.

[0070] Optionally, the paper feeding device further includes a third driving member 8. The third driving member 8 is connected to the second driving member 5 to drive the second driving member 5 to rise, so that the pressing plate 3 can correspond to the material stack 6.

[0071] Specifically, the second driving member 5 only operates to rub up the wrapping belt 61 to form a bulge, so its stroke is small. When regularizing the material stack 6 through the pressing plate 3, it is necessary to ensure that the pressing plate 3 can completely correspond to the material stack 6. Therefore, the third driving member 8 is provided. The output end of the third driving member 8 is connected to the second driving member 5 to drive the second driving member 5 to rise or fall, thereby pushing the pressing plate 3 to rise and fall.

[0072] Optionally, the stroke of the third driving member 8 is greater than the stroke of the second driving member 5 to ensure that the pressing plate 3 can completely correspond to the material stack 6 after rising. In this embodiment, the third driving member 8 can also be implemented by a cylinder. In other embodiments, the third driving member 8 can also be implemented by a motor cooperating with a screw.

[0073] By setting the third driving member 8, when it is necessary to regularize the material stack 6 through the pressing plate 3, the third driving member 8 and the second driving member 5 can operate synchronously, or only the third driving member 8 can be started, so that the pressing plate 3 rises to a position corresponding to the material stack 6. Then, when the first driving member 4 pushes the pressing plate 3, it can press against the side of the material stack 6 to achieve regularization. When it is necessary to squeeze the wrapping belt 61 to form a bulge, first reset the first driving member 4, the second driving member 5, and the third driving member 8. At this time, the first driving member 4 operates to push the pressing plate 3 to press against the wrapping belt 61, and the second driving member 5 operates to drive the pressing plate 3 to move upward to rub the wrapping belt 61 upward to smoothly form a bulge.

[0074] Optionally, the paper feeding device further includes a suction disc 9. The suction disc 9 is disposed through the pressing plate 3 for sucking the cut wrapping belt 61.

[0075] Specifically, a through notch is formed on the pressing plate 3, the suction disc 9 is disposed through the through notch, and the suction disc 9 corresponds to the wrapping belt 61. The suction disc 9 can be directly fixed on the pressing plate 3, or a separate driving structure can be provided to drive it to extend or contract. A plurality of suction discs 9 can be distributed at intervals, or only one suction disc 9 can be provided. The present utility model does not limit the number of suction discs 9.

[0076] By providing the suction disc 9, after the bulge of the wrapping belt 61 is cut, the suction disc 9 can approach the wrapping belt 61 to suck the wrapping belt 61. After sucking the wrapping belt 61, the suction disc 9 can reset to pull the wrapping belt 61 apart. At this time, the suction disc 9 stops sucking, so as to release the wrapping belt 61, so that the wrapping belt 61 no longer adheres to the material stack 6, facilitating the paper feeding of the wrapping belt 61.

[0077] Optionally, the paper feeding device further includes a fourth driving member 91. The fourth driving member 91 is connected to the suction disc 9 to drive the suction disc 9 to approach or move away from the material stack 6.

[0078] Optionally, the suction disc 9 is disposed at the output end of the fourth driving member 91, and the fourth driving member 91 can push the suction disc 9 to abut against the wrapping belt 61. Two fourth driving members 91 can be arranged at intervals, and the two fourth driving members 91 are respectively located on both sides of the first driving member 4. The fourth driving member 91 can be a cylinder or can be realized by a motor cooperating with a screw rod.

[0079] By providing the fourth driving member 91 and the suction disc 9, after the wrapping belt 61 is cut, the fourth driving member 91 drives the suction disc 9 to extend to suck the wrapping belt 61, and then the fourth driving member 91 resets to pull the wrapping belt 61 away from the material stack 6, so as to facilitate the suction of the suction cup on the cutting mechanism, so that the wrapping belt 61 can be pulled out from the material stack 6 through the cutting mechanism.

[0080] Optionally, the paper feeding device further includes a first mounting plate 41 and a pulling plate 42. The first driving member 4 is disposed on the first mounting plate 41; the pulling plate 42 is slidably connected to the first mounting plate 41, and at least part of the pulling plate 42 extends out of the first mounting plate 41 and is fixedly connected to the pressing plate 3.

[0081] Specifically, the first driving member 4 is fixedly disposed on the bottom wall of the first mounting plate 41. The first driving member 4 is located at the middle position of the first mounting plate 41. A slide rail is respectively disposed on the first mounting plate 41 on both sides of the first driving member 4. The pulling plate 42 is slidably connected to the slide rail, and the pulling plate 42 is fixedly connected to the pressing plate 3. The fixing method can be welding or bolt connection. For a more reasonable spatial layout, the fourth driving member 91 is fixed between the slide rail and the first driving member 4.

[0082] The pressing plate 3 is slidably connected to the first mounting plate 41 through the pull plate 42, ensuring that the pressing plate 3 is uniformly stressed as a whole. When the first driving member 4 acts to drive the pressing plate 3 to move, the side surface of the pressing plate 3 can be kept parallel to the side wall of the material stack 6, so that the pressing plate 3 can smoothly regularize the material stack 6 and can also smoothly abut against the wrapping belt 61.

[0083] Optionally, the paper rubbing device further includes a second mounting plate 51 and a guide post 52. The second driving member 5 is disposed on the second mounting plate 51; one end of the guide post 52 is fixedly connected to the first mounting plate 41, and the other end passes through the second mounting plate 51 and is slidably connected to the second mounting plate 51.

[0084] Specifically, the second mounting plate 51 is located below the first mounting plate 41, and the two are slidably connected through the guide post 52 and the guide sleeve. The second driving member 5 is fixed on the second mounting plate 51, and the output end of the second driving member 5 is connected to the first mounting plate 41. The second driving member 5 can drive the first mounting plate 41 to rise or fall. Similarly, a third mounting plate 81 is fixed on the third driving member 8, and the guide post 52 can be arranged to penetrate through the third mounting plate 81, so that the lifting and lowering of the second mounting plate 51 and the second mounting plate 51 can be kept in the same direction, and the third mounting plate 81 is arranged below the second mounting plate 51. A concave space can be provided on the base 1 to accommodate the third mounting plate 81.

[0085] Optionally, the paper rubbing device further includes a protective cover 13. The protective cover 13 covers the first driving member 4 and the second driving member 5.

[0086] Specifically, the protective cover 13 can cover the first mounting plate 41, the second mounting plate 51 and the third mounting plate 81 at the same time, so as to cover the first driving member 4, the second driving member 5, the third driving member 8 and the fourth driving member 91, so as to form a good dust-proof protection effect on the whole paper rubbing device.

[0087] Refer to Figure 5 and Figure 6 As shown in [relevant reference], the feeding device includes the paper rubbing device in the above-mentioned embodiment. The paper rubbing device is used to rub the wrapping belt 61 of the material stack 6 to form a bulge; the cutting and handling device is used to transport the material stack 6 to the paper rubbing device and can cut the bulge formed by the wrapping belt 61 of the material stack 6; the conveying device 10 is used to send the material stack 6 after cutting the wrapping belt 61 to the processing device.

[0088] On the outer side of the base 1, a material tray 20 can also be provided. The material tray 20 is used to hold multiple material stacks 6 with wrapping belts 61. The cutting and handling device includes a cutting mechanism 30 and a robot 40. The cutting mechanism 30 is arranged at the execution end of the robot 40, and the robot 40 is arranged between the material tray 20 and the base 1. In order to further simplify the complexity of the overall paper feeding device structure, the cutting mechanism 30 can have the function of handling the material stack 6. For example, a suction cup is arranged on the cutting mechanism 30. The suction cup can suck the material stack 6, and the cutting mechanism 30 is moved by the robot 40 to transport the material stack 6 containing the wrapping paper to the bearing table 2. At this time, the material stack 6 will pass through the rectifying device 7 and the paper feeding device for rectifying and extrusion, so that the wrapping belt 61 forms a bulge. After the cutting knife of the cutting mechanism 30 moves to cut the bulge of the wrapping belt 61, the wrapping belt 61 is extracted by the suction cup, and the next material stack 6 is transported. The material stack 6 with the wrapping belt 61 cut off is transported to the processing equipment through the conveying device 10 to complete the feeding of one material stack 6, and the extracted wrapping belt 61 can be recycled in a recycling box 50 specially arranged on the outer side of the base 1. By continuously repeating the above process, the automatic feeding of multiple material stacks 6 can be completed.

[0089] When the feeding equipment is in use, it can automatically form a bulge on the wrapping belt 61 by the paper feeding device, so that the cutting and handling device can smoothly cut the wrapping belt 61, enabling the large - batch material stacks 6 to be fully automated in the processes of handling, paper feeding, cutting, paper extraction and conveying, effectively reducing the degree of manual participation and being beneficial to improving the feeding efficiency.

[0090] The cigarette carton packaging supply line includes the feeding equipment as described in the above - mentioned embodiment. The feeding equipment is used to successively cut the wrapping belts 61 of multiple material stacks 6 and then send them to the packaging machine for processing.

[0091] When the cigarette carton packaging supply line is in use, the feeding equipment can automatically and orderly transport the material stacks 6 to the bearing table 2 of the paper feeding device in sequence, cut the wrapping belts 61 of the material stacks 6 and then send the materials to the packaging machine to complete the feeding. The whole feeding process can be fully automated, effectively improving the automation degree of feeding, reducing the degree of manual participation, and at the same time, it can also effectively reduce the possibility of the material stacks 6 falling apart, improving the stability and continuity of the feeding process.

[0092] Optionally, an intelligent vision safety system can be set up on the cigarette carton packaging supply line, that is, a depth camera is set up on the cigarette carton packaging supply line to collect the scene point cloud of the wire groove, and is communicatively connected to each structure within the cigarette carton packaging supply line to obtain the pose of each structure. A simulation scene without any obstacles or personnel is generated according to the pose, and then the actual scene and the simulation deposition are input into the neural network. Based on the 3D vision point cloud segmentation system formed by the deep learning neural network and the depth camera, the scene of the wire groove can be accurately identified, and it can be monitored in real time whether there are obstacles or personnel in the area of the cigarette carton packaging supply line, and the distance between each structure and the obstacles or personnel can be obtained in real time, so as to give early warnings of possible accidents or decelerate or even stop the actions of each structure to improve the safety performance of the entire supply line.

[0093] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
