Description

Technical Field

[0001] The present invention relates to the technical field of box-opening devices, and particularly to a cigarette box-opening device and a box-opening method. Background Art

[0002] During the process of sorting strip cigarettes, opening the cigarette box and ensuring the smooth ejection of strip cigarettes is a crucial link in cigarette box sorting.

[0003] Traditional box-opening devices usually use the front cover of the cigarette box as the reference side and only open the front cover of the cigarette box. The opening method of the rear cover mainly relies on manual operation, which has many deficiencies and safety hazards: First, the efficiency of manually opening the cigarette box is relatively low, making it difficult to meet the requirements of modern tobacco logistics for efficient distribution; Second, when manually opening the box, the working site is on a high-speed sorting production line, posing a relatively large safety hazard, and the edges of the cigarette box are sharp, making it easy for operators to be scratched when opening the rear cover of the cigarette box; In addition, the instability of manual operation may cause the rear cover of the cigarette box not to be fully opened, resulting in damage to the strip cigarettes inside the cigarette box when the subsequent cigarette pushing mechanism pushes the cigarettes, affecting the quality of tobacco products; When the demand for strip cigarette orders is large, the increase in manual labor intensity not only raises the labor cost but also affects the smoothness of the production line. Summary of the Invention

[0004] In view of the deficiencies of the prior art that rely on manual labor to open the rear cover of the cigarette box, which not only poses relatively large safety hazards but also affects the efficiency of cigarette box distribution, the present invention provides a cigarette box-opening device and a box-opening method, which open the rear cover of the cigarette box in an automated manner to further improve the efficiency of opening the cigarette box.

[0048] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention

[0049] It should be noted that when an element is referred to as "fixed to" or "disposed on" another component, it can be directly on the other component or indirectly disposed on the other component; when a component is referred to as "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.

[0050] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0051] Please refer to Figures 1 to 13 , the present invention provides a cigarette case opening device, which includes a conveying mechanism 1 disposed on the ground, box-scraping mechanisms 2 symmetrically disposed on both sides of the conveying mechanism 1, a front cover opening mechanism 3 disposed behind the box-scraping mechanism 2, and a rear cover opening mechanism 4 symmetric to the front cover opening machine with respect to the conveying mechanism 1; the cigarette case is conveyed on the conveying mechanism 1, first the sealing rubber strips of the front cover and the rear cover are scraped by the box-scraping mechanism 2, and then the cigarette case is opened by the front cover opening mechanism 3 and the rear cover opening mechanism 4 to complete the case opening operation.

[0052] In this embodiment, the cigarette case is placed at the head end of the conveying mechanism 1, and the cigarette case is conveyed by the conveying mechanism 1 to the position of the box-scraping mechanism 2 for box-scraping operation; through the operation of the box-scraping mechanism 2, the sealing rubber strips on the cigarette case are scraped; then the cigarette case is conveyed by the conveying mechanism 1 to between the front cover opening mechanism 3 and the rear cover opening mechanism 4. At this time, the sealing rubber strips of the front cover and the rear cover of the cigarette case are all scraped, and the upper, lower, left, and right pages of the front cover and the upper, lower, left, and right pages of the rear cover of the cigarette case are all opened by the front cover opening mechanism 3 and the rear cover opening mechanism 4 to complete the case opening operation of the device; then through the continuous movement of the conveying mechanism 1, the cigarette case with the front cover and the rear cover already opened is transported to the next process.

[0053] As Figures 2 to 6 shown, the box-scraping mechanism 2 includes: box-scraping frames 22 symmetrically installed on both sides of the transmission mechanism, X-axis adjustment modules 23 oppositely installed on the box-scraping frames 22, a Y-axis adjustment module 21 installed between the two X-axis adjustment modules 23, and box-scraping modules symmetrically installed on the Y-axis adjustment module 21.

[0054] As Figure 4As shown in the figure, the Y-axis adjustment module 21 includes: two first cross beams 211 installed parallel to each other in the Y-axis direction between two X-axis adjustment modules 23, a fixed beam 212 installed in the Z-axis direction between the two first cross beams 211, a top plate assembly 213 installed on the first cross beam 211 for fixing the cigarette box, and a Y-axis adjustment assembly installed on the first cross beam 211 for adjusting the sliding of the box dividing module in the Y-axis direction.

[0055] Furthermore, the box dividing module includes: a Z-axis control assembly 26 installed on the Y-axis adjustment module 21 through a cantilever connection frame 24, a suction cup assembly 27 installed on the cantilever connection frame 24, a second push plate assembly 28 installed at the bottom end of the cantilever connection frame 24, and a first glue scribing assembly 29 and a second glue scribing assembly 30 respectively installed on the Z-axis control assembly 26;

[0056] By controlling the Z-axis control assembly 26, the first glue scribing assembly 29 and the second glue scribing assembly 30 move synchronously towards or away from each other to cut open the central glue strip and the side glue strips of the cigarette box, and the upper and lower pages of the cigarette box are opened by the movement of the second push plate assembly 28.

[0057] In this embodiment, the X-axis adjustment module 23 includes: two first vertical beams 231 installed parallel to each other on the box dividing frame 22, an X-axis control guide rail 232 installed on the first vertical beam 231, and a number of X-axis control sliders 233 slidably installed on the X-axis control guide rail 232; the first cross beam 211 is fixedly installed with the X-axis control slider 233.

[0058] The Y-axis adjustment assembly includes: first Y-axis guide rails 214 respectively installed on the two first cross beams 211, a number of first Y-axis sliders 215 slidably installed on the first Y-axis guide rails 214, a cross beam plate 216 installed on the number of first Y-axis sliders 215, and a first telescopic cylinder 217 with a fixed end installed on the fixed beam 212. The telescopic end of the first telescopic cylinder 217 is installed with the cross beam plate 216, and the lower side surface of the cross beam plate 216 is fixedly installed with the cantilever connection frame 24.

[0059] Furthermore, when the cigarette box moves between the two box dividing modules, the top plate assembly 213 is adjusted to move to fixedly press the cigarette box by the sliding of the X-axis control slider 233 on the X-axis control guide rail 232. Then, by controlling the first telescopic cylinder 217, the cross beam plate 216 installed with the telescopic end of the first telescopic cylinder 217 slides on the first Y-axis guide rail 214 through the first Y-axis slider 215 to adjust the first glue scribing assembly 29 and the second glue scribing assembly 30 to a position suitable for the cigarette box; the cigarette box is fixedly adsorbed by controlling the suction cup assembly 27, and then the first glue scribing assembly 29 and the second glue scribing assembly 30 are controlled by the Z-axis control assembly 26 to move in the Z-axis direction to perform glue scribing operations on the sealing glue strips of the cigarette box. After the glue scribing operation is completed, the upper, lower, left, and right pages of the front cover and the rear cover of the cigarette box are separated by controlling the second push plate assembly 28.

[0060] Further, the top plate assembly 213 includes: a support plate 2131 installed between the two first cross beams 211, two upper top outer rods 2132 fixedly installed with the support plate 2131, and a lower top plate 2133 installed on the lower end surface of the upper top outer rods 2132. When the X-axis control slider 233 slides on the X-axis control guide rail 232 until the lower top plate 2133 presses against the top of the cigarette case, the adjustment of the X-axis is completed.

[0061] Further, the suction cup assembly 27 includes: a third cylinder 272 installed on the cantilever connecting frame 24 through a cylinder mounting bracket 271, a fourth cylinder 273 installed on the telescopic end of the third cylinder 272, a suction cup plate 274 installed on the telescopic end of the fourth cylinder 273, and a plurality of vacuum suction cups installed on the suction cup plate 274; by starting the third cylinder 272 and the fourth cylinder 273, the vacuum suction cups on the suction cup plate 274 can fixedly adsorb the cigarette case, facilitating the box-scoring operations of the first scoring assembly 29 and the second scoring assembly 30. The structure of the double cylinders can more freely adjust the distance between the vacuum suction cups and the cigarette case, ensuring the adsorption tightness of the vacuum suction cups to the cigarette case, and further ensuring the stability and efficiency of the operations of the first scoring assembly 29 and the second scoring assembly 30, thereby ensuring the overall operation efficiency of the device.

[0062] As Figures 5 to 6 shown, the Z-axis control assembly 26 includes: a second cylinder 261 installed on the cantilever connecting frame 24, a gear 262 installed on the cantilever connecting frame 24, a first rack 263 meshing with the upper side of the gear 262, a second rack 264 meshing with the lower side of the gear 262, two fixing blocks 265 installed on the cantilever connecting frame 24 in a staggered manner, and an auxiliary guide rail 266 fixedly installed on the rear sides of the first rack 263 and the second rack 264 and slidably installed with the fixing blocks 265; the first scoring assembly 29 and the second scoring assembly 30 are respectively installed on the first rack 263 and the second rack 264; the first scoring assembly 29 is fixedly installed with the telescopic end of the second cylinder 261.

[0063] The telescopic movement of the telescopic end of the second cylinder 261 drives the first scoring assembly 29 and the second scoring assembly 30 to move synchronously towards or away from each other; when the first scoring assembly 29 and the second scoring assembly 30 move from the middle to both sides, the central rubber strips of the front and rear covers of the cigarette case are scored; when the first scoring assembly 29 and the second scoring assembly 30 move to both sides of the cigarette case, the first scoring assembly 29 and the second scoring assembly 30 are adjusted to move in the X-axis direction to score the side rubber strips of the front and rear covers of the cigarette case.

[0064] In this embodiment, when the telescopic end of the second cylinder 261 extends, it drives the first rubber scraping assembly 29 to move in the Z-axis direction, so that the first rack 263 fixedly installed on the first rubber scraping assembly 29 meshes with the gear 262 and the gear 262 rotates accordingly. Then, the second rack 264 meshing with the gear 262 moves synchronously, and further, the second rubber scraping assembly 30 moves away from the first rubber scraping assembly 29. The opposite movement of the first rubber scraping assembly 29 and the second rubber scraping assembly 30 cuts open the central position of the cigarette case sealing strip.

[0065] After the central position of the rubber strip is completely cut open, the driving of the telescopic end of the second cylinder 261 is stopped, so that both the first rubber scraping assembly 29 and the second rubber scraping assembly 30 stay on both sides of the cigarette case. At this time, by adjusting the first rubber scraping assembly 29 and the second rubber scraping assembly 30, the two sides of the sealing strip are cut open, completing the rubber scraping operation on the cigarette case sealing strip.

[0066] As Figure 7 shown, the first rubber scraping assembly 29 includes: a first mounting plate 291 installed with the first rack 263, a first cylinder 292 installed on the first mounting plate 291, a first blade 294 installed on the telescopic end of the first cylinder 292 through a first connecting plate 293, a first track 295 installed on the first mounting plate 291, and a first sliding block 296 fixedly installed on the first connecting plate 293 and slidably installed on the first track 295; the first mounting plate 291 is fixedly installed with the telescopic end of the first cylinder 292.

[0067] In this embodiment, the only difference in the structure between the second rubber scraping assembly 30 and the first rubber scraping assembly 29 is that the setting direction of the second blade is opposite to the tip of the first blade 294. The initial positions of the first rubber scraping assembly 29 and the second rubber scraping assembly 30 are that the first mounting plate 291 abuts against the second mounting plate. At this time, the first blade 294 and the second blade overlap. Through the Z-axis control assembly 26, the first rubber scraping assembly 29 and the second rubber scraping assembly 30 move away from each other. Then, the first blade 294 and the second blade can start to move from the overlapping state and the movement distance gradually increases; this structure can further ensure that the central rubber strip of the cigarette case is completely cut open, improving the operation efficiency.

[0068] Furthermore, when the telescopic end of the first cylinder 292 is driven to extend, it drives the first connecting plate 293 installed on the telescopic end of the first cylinder 292 to move downward synchronously, so that the first blade 294 installed on the first connecting plate 293 moves accordingly. Then, the first sliding block 296 fixedly installed on the first connecting plate 293 can slide synchronously on the first track 295, controlling the first blade 294 to cut open the two side rubber strips of the cigarette case sealing strip; the matching setting of the first sliding block 296 and the first track 295 ensures the stability of the first blade 294 during rubber scraping and enhances the control of the first blade 294.

[0069] Further description is as follows. As Figure 7 shown, the first blade 294 includes a bending part 2941 with an end fixedly installed on the first connecting plate 293 and a box-scratching tip 2942 integrally formed with the bending part 2941. The sealing strip of the cigarette box can be scratched through the box-scratching tip 2942. The bending of the bending part 2941 makes the box-scratching tip 2942 not in the same plane as the outer side of the cigarette box. Thus, when the first glue-scratching assembly 29 and the second glue-scratching assembly 30 move, the box-scratching tip 2942 can scratch the sealing glue, and the integral forming can ensure the rigidity of the whole blade and the durability of the blade.

[0070] Further description is as follows. As Figure 5 shown, the second push plate assembly 28 includes: an electric push rod 281 fixedly installed on the cantilever connecting frame 24, and a push plate 282 installed on the telescopic end of the electric push rod 281. By controlling the telescopic end of the electric push rod 281 to extend, the push plate 282 pushes open all the upper, lower, left, and right pages of the front cover and the rear cover of the cigarette box scratched by the first blade 294 and the first blade 294, further ensuring that the four pages of the front cover and the rear cover of the cigarette box are all separated, improving the operation efficiency, and further ensuring the efficiency of the next process operation.

[0071] Further description is that the second glue-scratching assembly 30 moves synchronously with the first glue-scratching assembly 29, and thus the two synchronously scratch the glue strips on both sides of the sealing strip of the cigarette box.

[0097] Adjust the second X-axis sliding component 32 and the second Z-axis sliding component 33 to make the rotary adsorption component 47 on the second Z-axis sliding component adsorb and open the left and right pages of the front cover of the cigarette box.

[0098] S7. Convey the cigarette box with the upper page, the lower page, the left page, and the right page all opened to the next process through the conveying mechanism 1.

[0099] Further explanation is that the operation of cutting the rubber strips on both sides of the cigarette box can also be performed in step S4 first, then the operation of cutting the central rubber strip of the cigarette box in step S3, and finally control the second push plate component 28 to push along the Y-axis to push open the upper and lower pages corresponding to the front cover and the rear cover of the cigarette box that have been cut; the specific operation is as follows: the initial state of the second cylinder 261 is that its telescopic end is in the extended state. First, control the telescopic end of the first cylinder 292 to expand and contract, so that the first blade 294 and the second blade cut all the rubber strips on both sides of the front and rear covers of the cigarette box. Then, drive the first rubber strip cutting component 29 and the second rubber strip cutting component 30 to move from both sides to the central position by the retraction of the telescopic end of the second cylinder 261, so that the first blade 294 and the second blade cut the central rubber strip of the front and rear covers of the cigarette box. Finally, control the telescopic end of the electric push rod 281 to extend, so that the pushing plate 282 pushes open all the upper and lower pages of the front and rear covers of the cigarette box with the rubber strips all cut.

[0100] The specific steps of the opening method are as follows:

[0101] Place the front cover and the rear cover of the cigarette case on the conveying mechanism 1 with the sides facing the case splitting mechanism 2. Through the movement of the conveying mechanism 1, the cigarette case moves between the two case splitting modules. At the same time, control the first X-axis sliders 424 of the two case splitting modules to slide on the first X-axis guide rails 423, so that the lower top plate 2133 of the top plate assembly 213 can fix and press the cigarette case tightly.

[0102] Drive the two first telescopic cylinders 217. After synchronously adjusting the two case splitting modules to an appropriate distance from the cigarette case, control the third cylinder 272 and the fourth cylinder 273 so that the vacuum suckers of the sucker assembly 27 can simultaneously adsorb and fix both sides of the cigarette case. Then control the telescopic ends of the second cylinders 261 to extend synchronously from the initial positions, driving the first glue scraping assembly 29 fixedly installed on the telescopic ends of the second cylinders 261 to move accordingly. Furthermore, the first rack 263 fixedly installed on the first glue scraping assembly 29 moves synchronously. The gear 262 meshing with the first rack 263 moves accordingly, driving the second rack 264 meshing with the upper side of the gear 262 to move synchronously. Furthermore, the second glue scraping assembly 30 fixedly installed on the second rack 264 moves synchronously away from the first glue scraping assembly 29, completely cutting open the central rubber strips of the front cover and the rear cover of the cigarette case.

[0103] At this time, both the first glue scraping assembly 29 and the second glue scraping assembly 30 of the two case splitting modules are located on both sides of the cigarette case. Synchronously control the telescopic ends of the first cylinders 292 to extend and retract, so that the first blade 294 and the second blade completely cut open the rubber strips on both sides of the front cover and the rear cover of the cigarette case.

[0104] Control the telescopic end of the electric push rod 281 to extend, so that the pushing plate 282 pushes open the upper and lower pages of the front and rear covers of the cigarette case whose rubber strips have been completely cut open. At this time, the upper and lower pages of the front cover of the cigarette case are in a completely pushed-open state.

[0105] Through the continuous movement of the conveying mechanism 1, convey the cigarette case with the front and rear covers cut open to between the front cover opening mechanism 3 and the rear cover opening mechanism 4. Adjust the distance between the rotary adsorption assembly 47 installed on the first Z-axis slider 452 and the cigarette case by sliding the first X-axis slider 424 on the first X-axis guide rail 423, the load-bearing slider 434 on the load-bearing track 433, and in cooperation with the sliding of the first Z-axis slider 452 on the first Z-axis guide rail 451. When the rotary adsorption assembly 47 is adjusted to a suitable position, adjust the second X-axis sliding assembly 32 and the second Z-axis sliding assembly 33 to adjust the L-shaped clamping member 35 installed on the second Z-axis slider 333 to both sides of the cigarette case and clamp the cigarette case.

[0106] Control the telescopic end of the push plate cylinder 493 to extend, and the push plate 494 pushes open the upper and lower pages of the front and rear covers of the cigarette box, and exposes the left and right pages of the front and rear covers of the cigarette box; start the pneumatic rotary cylinders 472 on the first Z-axis slider 452 and the second Z-axis slider 333, so that the rotary disks 473 and the rotary rods 474 rotate accordingly, and then the vacuum suction cups installed on the rotary rods 474 adsorb and open the left and right pages of the front and rear covers of the cigarette box, completing the opening of the upper, lower, left and right pages of the cigarette box and the unpacking operation of the cigarette box.

[0107] Finally, the cigarette box after unpacking is transported to the next process through the movement of the conveying mechanism 1.
