Description

Technical Field

[0001] This invention belongs to the field of cigarette production technology and relates to a flexible unpacking device for sheet tobacco boxes on a cigarette manufacturing line, particularly a flexible unpacking device with correction function for unpacking sheet tobacco boxes on a Yunnan tobacco manufacturing line. Background Technology

[0002] Cigarettes generally refer to tobacco products made by rolling tobacco shreds into cigarette sticks and packaging them into strips, also known as paper cigarettes or cigarettes. In the production of cigarette tobacco shreds, it is necessary to first unpack the tobacco shreds used as raw materials, and then process the tobacco shreds by turning the pack, cutting and loosening the leaves, adding the raw materials, drying the shreds, and rolling them into cigarettes.

[0003] In existing cigarette cartons, the outer binding straps must be removed before the outer packaging can be disassembled. With modern development, to ensure efficiency in unpacking, robotic arms are often used to untie the outer binding straps. However, the robotic arm's program is often fixed, and its movement trajectory is also unchanging. During the untying process, the robotic arm is prone to shifting due to the position of the cigarette cartons, affecting the untying work. Furthermore, the robotic arm can easily damage the outer shell of the cigarette cartons and the internal tobacco leaves, thus affecting the quality of subsequent processing. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the problems that existing cigarette boxes are prone to displacement during unpacking, which affects the untying of the outer straps and causes damage to the outer shell and internal tobacco sheets by the robotic arm, thus affecting the quality of subsequent processing. Therefore, this invention proposes a flexible unpacking device for cigarette boxes on a dedicated tobacco processing line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Furthermore, the inflatable airbag is fixedly connected to the mounting groove opened in the rectangular insert plate, the inner side wall of the inflatable airbag is fixedly connected to a wear-resistant layer, a second elastic airbag is provided on one side above the inflatable airbag, one side of the second elastic airbag is fixedly connected to the inner side wall of the clamping block, and one side of the second elastic airbag is connected to an air outlet pipe.

[0011] Furthermore, the drive assembly includes a drive motor, the output shaft of which is fixedly connected to a rotating shaft, and the other end of the rotating shaft extends into the interior of the mounting plate and is fitted with a drive pulley. Both sides of the drive pulley are connected to driven pulleys via conveyor belts, and both the driven pulleys and the drive pulley are disposed within the mounting cavity opened in the mounting plate.

[0012] Furthermore, a lead screw is fitted inside the driven pulley, and a rectangular threaded sleeve is threadedly connected to the top of the lead screw after extending to the outside of the mounting plate. The top of the rectangular threaded sleeve is fixedly connected to the bottom of the fixing block. A second through hole is opened on both sides of the rectangular threaded sleeve, and a smooth rod is slidably arranged in the second through hole. The bottom end of the smooth rod is fixedly connected to the top of the mounting plate.

[0013] Furthermore, the auxiliary positioning component includes a fixed box, the bottom of which is fixedly connected to the top of the conveyor belt.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. In this invention, the gravity of the cigarette box drives the flat plate, guide rod, and first sliding block to move, transporting the gas inside the first elastic airbag to the inside of the contraction airbag, causing it to expand and drive the rectangular insert plate to extend out of the clamping block and insert into the inside of the cigarette box's outer binding strap. At the same time, the second sliding block transports the gas inside the second elastic airbag to the inside of the inflation airbag, causing it to expand and support the cigarette box's outer binding strap. This facilitates the robotic arm to unbind the cigarette box's outer binding strap, preventing damage to the cigarette box's outer shell and internal tobacco during the unbinding process, preventing any impact on the subsequent cigarette processing quality, improving the flexible unpacking of the cigarette box, and thus improving the product's applicability in use.

[0018] 2. In this invention, the movement position is limited by a T-shaped sliding block to prevent deviations in movement distance that could affect subsequent unpacking operations. A drive motor rotates the shaft, drive pulley, driven pulley, and lead screw, causing the lead screw to move the rectangular threaded sleeve and the fixing block vertically. When the cigarette box enters the interior of the fixing block, the first spring drives the sliding plate, connecting rod, and clamping block to fix the position of the cigarette box, preventing it from moving under external force when it is raised, which would affect the unpacking operation of the robotic arm and thus the unpacking of the product.

[0019] 3. In this invention, by driving the motor to rotate in the opposite direction, the rectangular threaded sleeve drives the fixed block to move downward, transporting the gas inside the rectangular airbag to the inside of the annular airbag. At this time, the gas inside the annular airbag will be greater than the elastic force of the second spring, causing the T-shaped sliding block to move into the fixed box, releasing the positioning of the smoke box. At the same time, the force of the second spring will continuously spray the gas inside the annular airbag through the capillary air outlet, causing the second sliding block to reset and limit the transmission position of the smoke box on the lower side. This facilitates automated production, reduces the labor costs of enterprises, and improves the economic benefits of enterprises. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figure 1-7A flexible unpacking device for sheet tobacco boxes on a dedicated tobacco processing line includes a conveyor belt 1. Auxiliary positioning components 7 are provided on both sides of the upper part of the conveyor belt 1. Multiple support frames 2 are fixedly connected to the bottom of the conveyor belt 1. An mounting plate 3 is fixedly connected to one side of each support frame 2. A driving component 4 is provided on the top of the mounting plate 3. Auxiliary fixing components 5 are provided on both sides of the top of the driving component 4. Each auxiliary fixing component 5 includes a fixing block 501, and a strap-opening component 6 is provided inside the fixing block 501. The strap-opening component 6 includes a first elastic airbag 601. The first elastic airbag 601 is located in the first inner cavity of the fixed block 501, and the bottom of the first elastic airbag 601 is fixedly connected to the inner wall of the fixed block 501. The top of the first elastic airbag 601 is fixedly connected to the first sliding block 602, which is slidably disposed in the first inner cavity. Guide rods 603 are fixedly connected to both sides of the top of the first sliding block 602. The top of the guide rods 603 extends to the outside of the fixed block 501 and is fixedly connected to a plate 604. The guide rods 603 are slidably disposed inside the fixed block 501.

[0032] The overall working process of this device is as follows:

[0033] The cigarette box to be unpacked is placed on the conveyor belt 1 for transport. It is guided by the round rod 11. The threaded sleeve 10 is manually rotated to the side away from the mounting frame 8, allowing adjustment of the threaded rod 9 and the round rod 11, improving the product's flexibility during use. When the top of the fixing block 501 contacts the bottom of the cigarette box, its gravity compresses the flat plate 604. Utilizing the linkage between the flat plate 604 and the guide rod 603, power is transmitted to the guide rod 603, causing it to move the first sliding block 602. This transports the gas inside the first elastic airbag 601 through the air pipe 605 to the inside of the contraction airbag 606, causing it to expand and move the second sliding block 607 horizontally. The linkage between the second sliding block 607 and the rectangular insert plate 608 further enhances the product's flexibility. The rectangular insert 608 extends outward from the clamping block 505 and inserts into the inner side of the strap. As the second sliding block 607 and the rectangular insert 608 move continuously, the second sliding block 607 compresses the second elastic airbag 611, and the gas inside the second elastic airbag 611 is transported to the air supply chamber 609 through the air outlet pipe. At this time, the gas inside the air supply chamber 609 is transported to the inflatable airbag 610 through the connecting pipe, causing it to expand and support the strap, making it easier for the robot arm 12 to untie the outer strap of the cigarette box. This prepares for the subsequent disassembly of the cigarette box's outer packaging carton, while preventing the robot arm 12 from damaging the outer shell and internal cigarettes during the untying process. This also facilitates the subsequent recycling of the carton, improves the flexible unpacking of the cigarette box, and thus improves the applicability of the product during use.

One side of the contraction airbag 606 is fixedly connected to the inner wall of the clamping block 505. A second sliding block 607 is fixedly connected to the other side of the clamping block 505. The sliding block 607 is slidably disposed in the third inner cavity opened inside the clamping block 505. A first through hole is opened on one side of the clamping block 505. A rectangular insert plate 608 is slidably disposed inside the first through hole. One side of the rectangular insert plate 608 is fixedly connected to the second sliding block 607. Both the rectangular insert plate 608 and the second sliding block 607 have air supply chambers 609. One side of the air supply chamber 609 is connected to a connecting pipe.

A wear-resistant layer is fixedly connected to the inner side wall of the inflatable airbag 610. A second elastic airbag 611 is disposed on the upper side of the inflatable airbag 610. One side of the second elastic airbag 611 is fixedly connected to the inner side wall of the clamping block 505. One side of the second elastic airbag 611 is connected to an air outlet pipe.

[0036] Its working process is as follows:

[0037] The drive motor 401 is started, causing the rotating shaft 402 to rotate. Utilizing the linkage effect between the rotating shaft 402 and the drive pulley 403, power is transmitted to the drive pulley 403, which then transmits the power to the driven pulley 404 via the conveyor belt. The linkage effect between the driven pulley 404 and the lead screw 405 transmits the power to the lead screw 405, causing the lead screw 405 to drive the rectangular threaded sleeve 406 to rotate in a circle and move vertically. Restricted by the two side rods, the rectangular threaded sleeve 406 can only move vertically, causing the rectangular threaded sleeve 406 to drive the fixed block 501 to move vertically. When the cigarette box enters the fixed block 501, the first spring 502 drives the sliding plate 503 to move. Utilizing the linkage effect between the sliding plate 503 and the connecting rod 504, the connecting rod 504 drives the clamping block 505 to fix the position of the cigarette box, preventing it from moving under external force when raised, thus affecting the untying operation of the robotic arm 12.

[0038] Example 2

[0039] The drive assembly 4 includes a drive motor 401. The output shaft of the drive motor 401 is fixedly connected to a rotating shaft 402. The other end of the rotating shaft 402 extends into the interior of the mounting plate 3 and is fitted with a drive pulley 403. Both sides of the drive pulley 403 are connected to driven pulleys 404 via conveyor belts. Both the driven pulleys 404 and the drive pulley 403 are located in the mounting cavity of the mounting plate 3. A lead screw 405 is fitted inside the driven pulley 404. The top of the lead screw 405 extends to the outside of the mounting plate 3 and is threaded with a rectangular threaded sleeve. 406, the top of the rectangular threaded sleeve 406 is fixedly connected to the bottom of the fixing block 501. Second through holes are provided on both sides of the rectangular threaded sleeve 406. A smooth rod is slidably installed in each of the second through holes. The bottom end of the smooth rod is fixedly connected to the top of the mounting plate 3. The auxiliary positioning assembly 7 includes a fixing box 701. The bottom of the fixing box 701 is fixedly connected to the top of the conveyor belt 1. A robot arm 12 is provided on one side of the conveyor belt 1. A mounting base is provided at the bottom of the robot arm 12. Multiple second springs 702 are fixedly connected to one side of the interior of the fixing box 701. A T-shaped sliding block 703 is fixedly connected to the other side of the spring 702. The T-shaped sliding block 703 is slidably disposed inside the fixed box 701. An annular airbag 704 is fixedly connected to one side of the T-shaped sliding block 703. The other side of the annular airbag 704 is fixedly connected to the inner wall of the fixed box 701. A capillary air outlet tube is connected to one side of the annular airbag 704, and an air inlet tube 705 is connected to the other side. The other end of the air inlet tube 705 extends to the outside of the fixed box 701 and connects to a rectangular airbag 706. The two sides of the rectangular airbag 706 are fixedly connected to the rectangular threaded sleeve 406 and the mounting plate 3 respectively. The other side of the rectangular airbag 706 is connected to the air inlet pipe. Both the air inlet pipe and the air inlet pipe 705 are equipped with one-way valves. Multiple mounting brackets 8 are provided on both sides of the fixed box 701. The bottom of the mounting bracket 8 is fixedly connected to the top of the conveyor belt 1 by screws. The top of the mounting bracket 8 is threadedly connected to the threaded rod 9. Two threaded sleeves 10 are provided on the threaded rod 9. The two threaded sleeves 10 are located on both sides of the mounting bracket 8 respectively. A round rod 11 is fixedly connected to the end of the threaded rod 9 away from the mounting bracket 8.

[0040] Its working process is as follows:

[0041] As the smoke box guided by the round rod 11 contacts the button on the T-shaped sliding block 703, the T-shaped sliding block 703 limits its movement position to prevent deviations in movement distance that could affect subsequent unpacking work and impact its center of gravity when the smoke box rises. After the unpacking work is completed, the drive motor 401 rotates in the opposite direction, causing the rectangular threaded sleeve 406 to move the fixing block 501 downwards. As the weight of the smoke box decreases, the elasticity of the first elastic airbag 601 causes the guide rod 603 and the plate 604 to move upwards. At the same time, the first elastic airbag 601 extracts gas from the inside of the contracting airbag 606 through the air supply pipe 605, causing the second sliding block 607 and the rectangular insert plate 608 to reset. The rectangular threaded sleeve 406 continues to move downwards, compressing the rectangular airbag 706. The gas inside the rectangular airbag 706 is then transported through the air inlet pipe 705 to the interior of the annular airbag 704. At this point, the gas inside the annular airbag 704 is greater than the elastic force of the second spring 702, causing the T-shaped sliding block 703 to move into the fixed box 701, releasing the positioning of the smoke box. Simultaneously, the force of the second spring 702 causes the gas inside the annular airbag 704 to be continuously ejected through the capillary air outlet pipe. The force of the second spring 702 also causes the second sliding block 607 to reset, limiting the transmission position of the smoke box on the lower side. This facilitates automated production, reduces the company's labor costs, and improves the company's economic efficiency.

[0042] Working principle of the invention:

[0043] In use, the cigarette box to be unpacked is placed on the conveyor belt 1 for transport. It is guided by the round rod 11. The threaded sleeve 10 is manually rotated to the side away from the mounting frame 8, thus adjusting the threaded rod 9 and the round rod 11. As the cigarette box is guided by the round rod 11, it contacts the button on the T-shaped sliding block 703, which limits its movement. At this time, the drive motor 401 is started, causing the rotating shaft 402 to rotate. Utilizing the linkage effect between the rotating shaft 402 and the driving pulley 403, power is transmitted to the driving pulley 403, which then transmits the power through the conveyor belt to the driven pulley 404. Utilizing the linkage effect between the driven pulley 404 and the lead screw 405, the power is then transferred to the driven pulley 404. The force is transmitted to the lead screw 405, causing the lead screw 405 to drive the rectangular threaded sleeve 406 to rotate in a circle and move vertically. Restricted by the two side rods, the rectangular threaded sleeve 406 can only move vertically, causing the rectangular threaded sleeve 406 to drive the fixed block 501 to move vertically. When the tobacco box enters the interior of the fixed block 501, the first spring 502 drives the sliding plate 503 to move. Utilizing the linkage effect between the sliding plate 503 and the connecting rod 504, the connecting rod 504 drives the clamping block 505 to fix the position of the tobacco box. When the top of the fixed block 501 contacts the bottom of the tobacco box, its gravity will compress the plate 604. Utilizing the linkage effect between the plate 604 and the guide rod 603, the power... The guide rod 603 moves the first sliding block 602, which in turn transports the gas inside the first elastic airbag 601 through the air supply pipe 605 to the inside of the contraction airbag 606, causing it to expand. This causes the second sliding block 607 to move horizontally. Utilizing the linkage effect between the second sliding block 607 and the rectangular insert 608, the rectangular insert 608 extends outward from the clamping block 505 and inserts into the inside of the strap. As the second sliding block 607 and the rectangular insert 608 continue to move, the second sliding block 607 compresses the second elastic airbag 611, transporting the gas inside the second elastic airbag 611 through the air outlet pipe to the inside of the air supply chamber 609. At this time, the gas inside the air supply chamber 609 is transported to the inflation chamber through the connecting pipe. The airbag 610 expands internally, supporting the straps and facilitating the robotic arm 12 to untie the outer straps of the cigarette box, preparing for the subsequent disassembly of the outer packaging carton. After the untying is completed, the drive motor 401 rotates in the opposite direction, causing the rectangular threaded sleeve 406 to move the fixed block 501 downwards. As the weight of the cigarette box decreases, the elasticity of the first elastic airbag 601 causes the guide rod 603 and the plate 604 to move upwards. Simultaneously, the first elastic airbag 601 extracts gas from the constricted airbag 606 through the air supply pipe 605, causing the second sliding block 607 and the rectangular insert plate 608 to reset. At this time, the rectangular threaded sleeve 406 continues to move downwards, compressing the rectangular airbag 706.The gas inside the rectangular airbag 706 is delivered to the annular airbag 704 through the air inlet pipe 705. At this time, the gas inside the annular airbag 704 is greater than the elastic force of the second spring 702, causing the T-shaped sliding block 703 to move into the fixed box 701, releasing the positioning of the smoke box. Simultaneously, the force of the second spring 702 continuously ejects the gas inside the annular airbag 704 through the capillary air outlet pipe. The force of the second spring 702 also causes the second sliding block 607 to reset, thus limiting the transmission position of the smoke box on the next side.
