[0001] The utility model relates to the technical field of cigarette packaging, in particular to a trademark paper conveying device. Background Art

[0002] At present, a part of the working steps of traditional cigarette packaging machines is as follows: the flattened trademark paper enters the packaging machine, and after applying glue to specific parts of the trademark paper, the trademark paper is folded to form a cigarette case. In order to ensure the accuracy of the glue application part and the symmetry of the cigarette case formed by folding the trademark paper, the trademark paper will be dispersed by a conveying device and positioned before entering the packaging machine.

[0003] The patent document with the publication number CN207482330U discloses such a cigarette case packaging device. Among them, the trademark paper conveying component is composed of a trademark paper longitudinal conveying component and a trademark paper transverse conveying component which are perpendicularly connected to each other. The trademark paper transverse conveying component includes a paper bin for storing trademark paper and a paper feeding die box connected to the paper bin. A lifting plate is provided at the front end of the paper feeding die box. The trademark paper longitudinal conveying component includes a roller, a steel stamping wheel, a glue applying wheel, a rubber wheel and a third pushing plate which are sequentially arranged on the upper surface. The roller is arranged at one end close to the lifting plate, and the third pushing plate is arranged at one end close to the No. 5 wheel component.

The trademark paper is only placed on the lifting plate. Once the horizontal moving speed of the lifting plate is too fast, due to inertia, the trademark paper is likely to shift, affecting the subsequent glue application accuracy and folding symmetry of the trademark paper.

Detailed implementation manners

[0023] The following are the detailed implementation manners of the utility model. In combination with the drawings, the technical solutions of the utility model are further described, but the utility model is not limited to these embodiments.

[0024] A label paper conveying device, as Figure 1 shown, includes a low-level horizontal conveyor line 1 and a high-level vertical conveyor line 2; as Figure 2 shown, the conveying direction of the horizontal conveyor line 1 is perpendicular to the conveying direction of the vertical conveyor line 2.

[0025] As Figure 1 shown, the left end of the horizontal conveyor line 1 is the inlet end, where a hopper is usually provided, and the label paper 10 falls onto the horizontal conveyor line 1 from the hopper one after another; the right end of the horizontal conveyor line 1 is the outlet end, and the label paper 10 on the horizontal conveyor line 1 is transferred to the vertical conveyor line 2 at this end. As Figure 2, the horizontal conveyor line 1 generally includes two conveyor belts. The upper and lower ends of the label paper 10 are respectively lapped on the two conveyor belts. Usually, limit plates are also arranged on the two conveyor belts, and the upper and lower ends of the label paper 10 are respectively abutted against the two limit plates to limit the position of the label paper 10. A number of baffles are also equidistantly installed between the two conveyor belts. The upper and lower ends of the baffles are respectively detachably connected to the two conveyor belts, for example, through a stud and screw hole structure, so that the distance between adjacent baffles can be adjusted. By adjusting the distance between adjacent baffles to the width of the label paper 10, the label paper 10 is limited between the two baffles, further restricting the position of the label paper 10 and preventing the label paper 10 from shifting during horizontal transportation.

[0026] Such as Figure 2 , the lower end of the vertical conveyor line 2 is the inlet end for receiving the label paper 10 coming out of the outlet end of the horizontal conveyor line 1; the upper end of the vertical conveyor line 2 is the outlet end for sending the label paper to the folding structure in the packaging machine; usually, a glue application structure is also arranged above the vertical conveyor line 2 to apply glue to the label paper 10 on the vertical conveyor line 2. The vertical conveyor line 2 also includes two conveyor belts 21. A number of receiving plates 22 are equidistantly installed between the two conveyor belts 21. Different from the baffles in the above-mentioned horizontal conveyor line 1, the label paper 10 is directly placed on the receiving plates 22, and the two ends of the receiving plates 22 can be respectively fixedly connected to the two conveyor belts 21.

[0027] Since the widths of different label papers 10 are different, in the horizontal conveyor line 1, the distance between the two baffles can be adjusted to fit the width of the label paper 10; in the vertical conveyor line 2, the width of the receiving plate 22 is usually larger to allow the placement of label papers 10 with different widths, which involves the positioning problem of the label paper 10 on the vertical conveyor line 2. In order to ensure that the central axes of a number of label papers 10 coincide with the central axis of the vertical conveyor line 2, the vertical conveyor line 2 also includes two movable baffles 23 arranged between the two conveyor belts 21 and parallel to the conveying direction of the vertical conveyor line 2, and a second adjusting member for adjusting the distance between the two movable baffles 23. The label paper 10 is restricted to the center of the vertical conveyor line 2 by the two movable baffles 23. Usually, a lubricating layer is also arranged on the surface of the movable baffles 23 to reduce the friction with the label paper 10.

[0028] At this time, it is also related to the adjustment and fixation of the movable baffle 23. Therefore, fixed baffles 211 are respectively provided on both sides of the longitudinal conveyor line 2 parallel to the conveying direction. At this time, the second adjusting member may include a screw 241, two nuts 242 provided on the screw 241, and a through hole provided on the fixed baffle 211. During use, the head of the screw 241 is connected to the movable baffle 23, and the screw 214 is perpendicular to the movable baffle 23. The head of the screw 241 can be directly welded to the movable baffle 23, or a connection hole can be provided on the movable baffle 23 so that the end of the screw 241 passes through the connection hole and the head of the screw 241 abuts against the movable baffle 23. Then, a nut 242 is sleeved on the screw 241 first, and then the end of the screw 241 is passed through the through hole of the fixed baffle 211, and then a nut 242 is sleeved on the screw 241. After adjusting the distance between the movable baffle 23 and the fixed baffle 211, rotate the two nuts 242 so that the two nuts 242 respectively abut against the two side surfaces of the fixed baffle 211. When the movable baffle 23 needs to be adjusted, rotate the two nuts 242 in the reverse direction so that the two nuts 242 no longer abut against the fixed baffle 211, and then move the movable baffle 23. At this time, only the adjustment of the distance between the two movable baffles 23 is realized, but it is still impossible to ensure that the central axis between the two movable baffles 23 coincides with the central axis of the longitudinal conveyor line 2. Therefore, usually, an adjusting tooling 5 is additionally provided. As Figure 3 shown, the adjusting tooling 5 includes a fixing part 51 and an adjusting part 52. The central axis of the fixing part 51 coincides with the central axis of the adjusting part 52. The adjusting part 52 is detachably connected to the fixing part 51, so that different adjusting parts 52 can be replaced. Usually, threaded holes can be provided on the central axis of the fixing part 51 and the central axis of the adjusting part 52, and the fixing part 51 and the adjusting part 52 are connected by screws. After selecting an adjusting part 52 with the same width as the width of the label paper 10 and installing it on the fixing part 51, the fixing part 51 is clamped between the two conveyor belts 21, and the two ends of the fixing part 51 respectively abut against the two conveyor belts 21. At this time, the adjusting part 52 is exactly located on the central axis between the two conveyor belts 21. Then, move the two movable baffles 23 so that the two ends of the adjusting part 52 respectively abut against the two movable baffles 23. Then, fix the movable baffle 23 through the above-mentioned second adjusting member, and remove the adjusting tooling 5, then it can be ensured that the central axis between the two movable baffles 23 coincides with the central axis of the longitudinal conveyor line 2, and the distance between the two movable baffles 23 is the same as the width of the label paper 10.

[0029] After the structures of the horizontal conveyor line 1 and the longitudinal conveyor line 2 are set up, it can be ensured that the label paper 10 does not shift during its transportation thereon, and the positioning of the label paper is accurate. However, there is still an offset problem in the transfer of the label paper 10 between the horizontal conveyor line 1 and the longitudinal conveyor line 2. Therefore, in this application, as Figure 1 shown, it further includes a transfer member provided at the outlet end of the horizontal conveyor line 1 for transferring the label paper 10 on the horizontal conveyor line 1 to the longitudinal conveyor line 2.

[0030] The transfer member includes a suction plate 41 suspended above the horizontal conveyor line 1 and the vertical conveyor line 2, a lifting structure for driving the suction plate 41 to move in the vertical direction, and a translation structure for driving the suction plate 41 to move in a direction parallel to the conveying direction of the horizontal conveyor line 1. The suction plate 41 is provided with a plurality of suction holes communicated with the negative pressure structure. Among them, the lifting structure can adopt a cylinder. The translation structure includes a guide rail 421 suspended above the horizontal conveyor line 1 and the vertical conveyor line 2. A ball screw 422 is arranged in the guide rail 421. The ball screw 422 is a common structure that converts rotational motion into linear motion. When the ball screw is the driving body, the nut on it will be converted into linear motion according to the lead of the corresponding specification with the rotation angle of the screw rod. The passive workpiece can be connected through the nut seat and the nut, so as to realize the corresponding linear motion. Therefore, the cylinder is connected to the nut of the ball screw 422, and the suction plate 41 is connected to the piston rod of the cylinder.

[0031] In use, first, the cylinder and the adsorption plate 41 are driven by the ball screw 422 to move horizontally above the outlet end of the horizontal conveyor line 1. Then, the cylinder drives the adsorption plate 41 to descend until it abuts against the top surface of the label paper 10. The negative pressure structure is turned on, and the adsorption plate 41 adsorbs the label paper 10 by negative pressure. The adsorption process basically will not cause the offset of the label paper 10. However, to further ensure that the label paper 10 does not offset, two clamping baffles 43 can be provided on the adsorption plate 41. The length direction of the clamping baffles 43 is parallel to the conveying direction of the longitudinal conveyor line 2. There is also a first adjusting member for adjusting the distance between the two clamping baffles 43. For example, a sliding groove 412 is provided on the adsorption plate 41. The length direction of the sliding groove 412 is perpendicular to the conveying direction of the longitudinal conveyor line 2. The clamping baffles 43 are slidably arranged in the sliding groove 412 through sliders. The distance between the two clamping baffles 43 can be adjusted by sliding the clamping baffles 43. Two sliding grooves 412 can also be provided on the adsorption plate 41. Ball screw structures are respectively arranged in the two sliding grooves 412. The slider of one clamping baffle 43 is connected to the nut of one ball screw structure. The movement and fixation of the clamping baffle 43 are controlled by the ball screw structure. After adjusting the distance between the two clamping baffles 43 to the width of the label paper 10, the label paper 10 on the horizontal conveyor line 1 is adsorbed, and the label paper 10 can be restricted between the two clamping baffles 43 to avoid the offset of the label paper 10. After the label paper 10 is adsorbed, the cylinder drives the adsorption plate 41 and the label paper 10 to rise, and then the ball screw 422 drives the cylinder, the adsorption plate 41 and the label paper 10 to move horizontally above the longitudinal conveyor line 2 together. Finally, the cylinder drives the adsorption plate 41 and the label paper 10 to descend, so that the label paper 10 approaches the receiving plate 22 on the longitudinal conveyor line 2. Then the negative pressure structure is turned off to release the adsorption of the label paper 10, and the label paper 10 falls onto the receiving plate 22. At this time, in order to avoid the adhesion of the adsorption plate 41 itself to the label paper 10, the surface of the adsorption plate 41 for abutting against the label paper 10 is provided with a non-stick coating, such as a polytetrafluoroethylene coating. At the same time, adsorption holes can also be provided on the receiving plate 22 and connected to the negative pressure structure. After the negative pressure structure connected to the adsorption plate 41 is turned off, the negative pressure structure connected to the receiving plate 22 is turned on to accelerate the fall of the label paper 10 onto the receiving plate 22. Among them, based on the limiting effect of the movable baffle 23 mentioned above, whether the label paper 10 naturally falls onto the receiving plate 22 or is adsorbed onto the receiving plate 22, the label paper 10 will not offset.

[0032] In order to enable the label paper 10 to be accurately translated above the part between the two movable baffles 23, a positioning plate is provided on the movable baffle 23 away from the transverse conveying line 1 among the two movable baffles 23, and a positioning surface 231 is formed on the surface of the positioning plate close to the transverse conveying line 1; among the two clamping baffles 43, the clamping baffle 43 close to the longitudinal conveying line 2 is provided with a stop surface 431 that abuts against the positioning surface 231. After the translation structure drives the clamping baffle 43 to move until the stop surface 431 abuts against the positioning surface 231, it cannot continue to translate. At this time, the clamping baffle 43 and the movable baffle 23 are exactly aligned, ensuring the accuracy of the falling of the label paper 10. At the same time, ferromagnetic sheets and magnetic attraction sheets can be respectively arranged on the end faces of the movable baffle 23 and the clamping baffle 43, so that the movable baffle 23 and the clamping baffle 43 can be magnetically attracted and fixed.

[0033] In addition, when the adsorption plate 41 negatively adsorbs the label paper 10 on the transverse conveying line 1, it may also adsorb the label paper 10 near the target label paper 10, causing unnecessary deviation of these label papers 10. Therefore, in this application, a lifting member is also included. The lifting member 3 includes a lifting plate 31 and a telescopic structure 32 that drives the lifting plate 31 to lift until it abuts against the bottom surface of the label paper 10 and continues to drive the label paper 10 to lift. The telescopic structure 32 can also adopt a cylinder. During use, first, the telescopic structure 32 drives the lifting plate 31 to rise until it abuts against the bottom surface of the label paper 10, and then the lifting and lowering structure drives the adsorption plate 41 to descend until it abuts against the top surface of the label paper 10. The label paper 10 is fixed between the lifting plate 31 and the adsorption plate 41. Without turning on the negative pressure structure, the telescopic structure 32 and the lifting and lowering structure are directly controlled to rise synchronously; after rising above the plane where the longitudinal conveying line 2 is located, the negative pressure structure is then turned on, and the adsorption plate 41 negatively adsorbs the label paper 10; then the lifting and lowering structure and the adsorption plate 41 are driven to move horizontally above the longitudinal conveying line 2 through the ball screw 422; finally, the adsorption plate 41 is driven to descend through the lifting and lowering structure, so that the label paper 10 approaches the receiving plate 22 on the longitudinal conveying line 2, and then the negative pressure structure is turned off to release the adsorption of the label paper 10.
