Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to an adjustable carton magazine for a carton sealing machine. Background Technology

[0002] Currently, in the tobacco industry, when a malfunction occurs on the overhead conveyor line for cigarettes or at the end of the overhead conveyor line, resulting in a shutdown of more than 30 minutes, the cigarette cartons are manually stacked and placed into cartons at the cigarette carton exit of the packaging machine for packaging. This method ensures efficient production without stopping the packaging machine. This process involves the storage of unopened cartons (i.e., carton stock) and the loading of cartons.

[0003] Currently, carton opening is done manually. Typically, after unstacking the carton stack, a suction device picks up each carton individually and unfolds them. During this process, the cartons are prone to sticking together, leading to opening failures. Secondly, as the number of cartons decreases, their feeding position changes, resulting in inconsistent opening operations and reduced production efficiency.

[0004] Therefore, there is a need for an adjustable carton magazine for a carton packing machine that can store cartons and supply them to the suction unit to improve production efficiency. Utility Model Content

[0047] Example 1:

[0048] Please refer to Figure 1-12 This embodiment provides an adjustable carton magazine for a carton sealing machine, including a frame 10, and a belt assembly, a carton pressing assembly, and a carton blocking assembly mounted on the frame 10.

[0049] The frame 10 mainly serves a supporting and connecting function. The frame 10 includes an upper frame and a lower frame, both used to fix various components, thereby configuring the adjustable carton magazine of this embodiment in the carton sealing machine. A material storage station 11 is formed on the frame 10 of this embodiment. A material replenishment inlet 12 and a material supply outlet 13 are formed at both ends of the material storage station 11. The material replenishment inlet 12 is used to fill the material storage station 11 with carton material, and the material supply outlet 13 is used to connect with the carton opening component of the carton sealing machine to supply carton material to the carton sealing machine.

[0050] The belt assembly is located at the bottom of the storage station 11, and the belt assembly is used to support the box material at the storage station 11.

[0051] The pressing box component includes a rear pressing box plate 431 that can slide relative to the frame 10, the rear pressing box plate 431 applying a pressing force to the box material in the storage station 11 in the direction of the feeding outlet 13.

[0052] The baffle component is disposed at the feed outlet 13 and is used to open or close the feed outlet 13.

[0053] In this embodiment, the adjustable carton magazine of the carton sealing machine is fixed to its components by the frame 10 and configured within the carton sealing machine. During use, carton material is fed into the storage station 11 through the feeding inlet 12. The carton material is stored in the storage station 11 under the support of the belt conveyor at the bottom. A pressing component applies a pressing force to the carton material in the storage station 11, pointing towards the feeding outlet 13, pressing the carton material towards the feeding outlet 13. As the equipment operates, even if the amount of carton material in the storage station 11 continuously decreases, the position of the feeding outlet 13 remains constant. A blocking component opens or closes the feeding outlet 13 to intercept or release the carton material, confining it within the storage station 11 or supplying it to the carton sealing machine through the feeding outlet 13. This achieves the storage of cartons and the supply of cartons to the suction component, improving production efficiency.

[0054] Specifically, the baffle assembly includes an upper baffle assembly 60 and a lower baffle assembly 70. The lower baffle assembly 70 is installed on the frame 10 and is used to intercept or release the lower edge of the box material. The upper baffle assembly 60 is used to intercept or release the upper edge of the box material.

[0055] Furthermore, left and right baffle components can be installed on both sides of the material supply outlet 13 to intercept or release the material at the left and right edges.

[0056] The lower baffle box component 70 of this embodiment includes a lower baffle box mounting base 72, a lower baffle box drive component 73, and a lower baffle box plate 71. The lower baffle box mounting base 72 is fixedly connected to the frame 10, and the lower baffle box plate 71 is hinged to the lower baffle box mounting base 72. The lower baffle box drive component 73 has a fixed end and a telescopic end. The lower baffle box drive component 73 is a mini cylinder. The fixed end of the lower baffle box drive component 73 is connected to the lower baffle box mounting base 72, and the telescopic end of the lower baffle box drive component 73 is hinged to the lower baffle box plate 71 through a swing arm. The lower baffle box drive component 73 provides power to drive the lower baffle box plate 71 to rotate relative to the lower baffle box mounting base 72, thereby intercepting or releasing the lower edge of the box material.

[0057] The upper baffle box component 60 includes an upper baffle box mounting base 62, which is slidably connected to the frame 10 via a longitudinal adjustment shaft 66. A locking element is provided at the connection between the longitudinal adjustment shaft 66 and the frame 10. The upper baffle box component 60 is moved vertically relative to the frame 10 by the longitudinal adjustment shaft 66 to adjust the height of the feeding outlet 13 to meet the supply requirements of different specifications of box materials. The locking element locks the relative position of the longitudinal adjustment shaft 66 and the frame 10 by means of a clamping shaft.

[0058] The upper baffle box component 60 also includes an upper baffle box drive component 63 and an upper baffle box plate 61; the upper baffle box plate 61 is hinged to the upper baffle box mounting base 62, and the upper baffle box drive component 63 has a fixed end and a telescopic end. In this embodiment, the upper baffle box drive component 63 is a mini cylinder. The fixed end of the upper baffle box drive component 63 is connected to the upper baffle box mounting base 62, and the telescopic end of the upper baffle box drive component 63 is hinged to the upper baffle box plate 61 through a swing arm; the upper baffle box drive component 63 provides power to drive the upper baffle box plate 61 to rotate relative to the upper baffle box mounting base 62, thereby intercepting or releasing the upper edge of the box material.

[0059] The upper baffle box component 60 further includes an upper pressure box block 64 and an upper pressure box drive component 65. The upper pressure box drive component 65 has a fixed end and a telescopic end. In this embodiment, the upper pressure box drive component 65 adopts a three-axis cylinder. The fixed end of the upper pressure box drive component 65 is connected to the upper baffle box mounting base 62, and the telescopic end of the upper baffle box drive component 65 is connected to the upper pressure box block 64. A release gap 131 is formed between the upper pressure box block 64 and the upper baffle plate 61, and the release gap 131 allows one box of material to enter. Power is provided by the upper pressure box drive component 65 to drive the upper pressure box block 64. The box block 64, positioned near or away from the storage station 11, presses down several boxes on one side of the release gap 131, thereby confining other boxes outside the release gap 131 within the storage station 11. This means the first box near the supply outlet 13 can be supplied to the box-sealing machine for subsequent processes, while the second and subsequent boxes are pressed down by the upper box block 64 to prevent them from being carried out of the storage station 11 along with the first box. This allows for the release of one box at a time, supplying boxes to the box-sealing machine sequentially, preventing boxes from sticking together and causing opening failures that could affect subsequent processes. Furthermore, the bottom of the upper box block 64 may have several grooves adapted to the boxes, further confining them within the storage station 11.

[0060] The belt assembly in this embodiment includes a first belt assembly 20 and a second belt assembly 30, which together support and transport the boxed material on the storage station 11; the pressing assembly includes a first pressing assembly 40 and a second pressing assembly 50, which together apply a pressing force to the boxed material in the storage station 11 in the direction of the feeding outlet 13.

[0061] The frame 10 is horizontally provided with frame 10 guide rails, and the frame 10 guide rails are sequentially slidably connected with a first pressure box mounting plate 14, a first belt mounting plate 15, a second belt mounting plate 16, and a second pressure box mounting plate 17; the first pressure box mounting plate 14 and the second pressure box mounting plate 17 are respectively used to install the first pressure box component 40 and the second pressure box component 50, and the first belt mounting plate 15 and the second belt mounting plate 16 are respectively used to install the first belt component 20 and the second belt component 30.

[0062] The first pressure box mounting plate 14, the first belt mounting plate 15, the second belt mounting plate 16, and the second pressure box mounting plate 17 are respectively connected to the frame 10 through the adjustment assembly 18.

[0063] The first adjustment component 18 includes an adjustment handwheel and an adjustment screw. The adjustment screw is rotatably connected to the frame 10 through a screw seat. One end of the adjustment screw is screwed to the first pressure box mounting plate 14, and the other end is connected to the adjustment handwheel. By rotating the adjustment handwheel, the adjustment screw drives the first pressure box mounting plate 14 to translate relative to the frame 10.

[0064] This embodiment uses the adjustment assembly 18 between the first pressure box mounting plate 14 and the frame 10 as an example. Similarly, the adjustment assembly 18 between the second belt mounting plate 16, the second pressure box mounting plate 17 and the frame 10 can be implemented using the above structure.

[0065] The distance between the first pressure box mounting plate 14 and the second pressure box mounting plate 17 is controlled by adjusting component 18, thereby controlling the relative position of the first pressure box component 40 and the second pressure box component 50; the distance between the first belt mounting plate 15 and the second belt mounting plate 16 is controlled by adjusting component 18, thereby controlling the distance between the first belt component 20 and the second belt component 30, so that it can adapt to box materials of different specifications and sizes, making it more practical.

[0066] Specifically, the first belt component 20 includes a belt mounting frame 21, which is fixed to the first belt mounting plate 15; the belt mounting frame 21 is provided with a belt conveyor assembly 22, which is used to drive the box material on the storage station 11 to move from the material replenishment inlet 12 to the material supply outlet 13.

[0067] The belt conveyor assembly 22 includes a drive wheel, a driven wheel, a conveyor belt, and a servo motor. The drive wheel and the driven wheel are respectively connected to opposite ends of the belt mounting frame 21 through bearing seats. The conveyor belt is sleeved around the drive wheel and the driven wheel. The servo motor is linked to the drive wheel through a reducer and a transmission assembly. The servo motor provides power to drive the drive wheel and the driven wheel to rotate. The conveyor belt contacts the bottom of the box material, driving the box material on the storage station 11 to move from the feeding inlet 12 to the feeding outlet 13.

[0068] The belt mounting frame 21 is provided with a positioning inspection component 23 at one end near the material supply outlet 13. The positioning inspection component 23 is used to detect whether there is box material stored in the release gap 131. Based on the positioning inspection component 23 detecting whether there is box material stored in the release gap 131, the belt conveyor component 22 is controlled to drive the box material on the storage station 11 to move until the box material enters the release gap 131.

[0069] The positioning inspection component 23 includes a positioning swing plate 231, a positioning inspection plate 232, a slotted photoelectric sensor 233, and a tension spring 234. The positioning swing plate 231 is hinged to the end of the belt mounting frame 21. The positioning swing plate 231 has a toggle part 2311, which extends into the storage station 11. When there is box material in the release gap 131, the box material pushes the positioning swing plate 231 to rotate to the first position through the toggle part 2311. When there is no box material in the release gap 131, the positioning swing plate 231 rotates to the second position. One end of the tension spring 234 is connected to the positioning swing plate 231, and the other end is connected to the belt mounting frame 21. The tension spring 234 provides an elastic force to drive the positioning swing plate 231 to rotate from the first position to the second position. The positioning inspection plate 232 is connected to the positioning swing plate 231, and the slotted photoelectric sensor 233 is fixed to the end of the belt mounting frame 21.

[0070] When there is no box material in the release gap 131, the positioning swing plate 231 rotates to the second position. The positioning swing plate 231 drives the positioning inspection plate 232 to disconnect from the slotted photoelectric sensor 233. The slotted photoelectric sensor 233 sends a feeding signal to control the belt conveyor assembly 22 to move the box material on the storage station 11 until the box material enters the release gap 131 and contacts the actuating part 2311 to push the positioning swing plate 231 to rotate to the first position.

[0071] The structure of the second belt component 30 is the same as that of the first belt component 20, and the two are arranged opposite each other. This will not be described in detail here, as those skilled in the art will understand.

[0072] The first pressure box component 40 in this embodiment includes a pressure box mounting bracket 41, which is fixed on the first pressure box mounting plate 14;

[0073] The first pressing box component 40 is equipped with an excess material detection sensor 42. When the box material in the storage station 11 drops to a preset quantity, the excess material detection sensor 42 is triggered to send a replenishment signal.

[0074] The first pressing box component 40 further includes a pressing box assembly 43; the pressing box assembly 43 includes a pressing box plate seat 434, the pressing box plate seat 434 is connected to the pressing box mounting frame 41 through a slider guide mechanism, and a spring balancer 432 is provided between the pressing box plate seat 434 and the pressing box mounting frame 41. The spring balancer 432 provides an elastic force to drive the pressing box plate seat 434 to move from the feeding inlet 12 to the feeding outlet 13.

[0075] The rear pressure plate 431 is rotatably connected to the pressure plate seat 434 via the pressure plate rod 433. An elastic element 435 is provided at the connection between the pressure plate rod 433 and the pressure plate seat 434. The elastic element 435 can be a torsion spring or a tension spring. The elastic element 435 provides an elastic force that drives the rear pressure plate 431 to press the box material toward the feeding outlet 13.

[0076] The first pressure box component 40 further includes a push plate assembly 44, which includes a push plate seat 441 and a push plate drive structure 442. The push plate seat 441 is connected to the pressure box mounting frame 41 through a slider guide mechanism. The push plate drive structure 442 is linked with the push plate seat 441. The push plate drive structure 442 includes a drive wheel, a driven wheel, a tension wheel, a belt, and a servo motor. The drive wheel and the driven wheel are respectively connected to the two ends of the pressure box mounting frame 41 through bearing seats. The tension wheel is rotatably connected between the drive wheel and the driven wheel. The belt is sequentially sleeved around the drive wheel, the driven wheel, and the tension wheel in the circumference. The servo motor is fixed to the pressure box mounting frame 41 through a motor seat and is linked with the drive wheel through a transmission mechanism. The push plate seat 441 is connected to the belt through a belt clamp. A rubber-coated screw 4411 is fixed on one side of the push plate seat 441. The push plate drive structure 442 drives the push plate seat 441 to move relative to the pressure box mounting frame 41. The rubber-coated screw 4411 on the side of the push plate seat 441 contacts the pressure box plate seat 434, driving the pressure box assembly 43 to move horizontally to the material inlet 12.

[0077] The adjustable carton magazine of the carton sealing machine in this embodiment is mainly responsible for storing carton materials and supplying them to the suction component. During the operation of the carton sealing machine, when the suction cup of the suction component of the carton sealing machine picks up the upper half of the carton material in the release gap 131, the upper pressure carton drive 65 drives the upper pressure carton block 64 to approach the storage station 11 and press down the second and subsequent carton materials; then the upper baffle carton drive 63 drives the upper baffle plate 61 to swing open, and at the same time the lower baffle carton drive 73 drives the lower baffle plate 71 to swing open, opening the material supply outlet 13, and then the suction component pulls out the carton material to form it. Then, the upper and lower baffle plates 61 and 71 return to their original positions, and the upper pressure box drive component 65 drives the upper pressure box block 64 to retract. Since the box material in the release gap 131 has been removed, the position of the release gap 131 is vacated, so that the positioning swing plate 231 of the belt assembly is not blocked by a carton. The positioning swing plate 231 is pulled by the tension spring 234 to swing to the second position, thereby causing the positioning check plate 232 to disengage from the slotted photoelectric sensor 233. The signal of the slotted photoelectric sensor 233 is disconnected, and the belt conveyor assembly 22 starts to transport the second carton material into the release gap 131, which contacts the actuating part 2311 and pushes the positioning swing plate 231 to rotate to the first position. The belt conveyor assembly 22 stops running after the slotted photoelectric sensor 233 receives the signal again, and the feeding is carried out in this cycle. The pressing component is equipped with an excess material detection sensor 42. When it detects that the carton material in the storage station 11 is insufficient, a replenishment prompt will be issued. During material replenishment, the push plate drive structure 442 drives the rubber-coated screw 4411 on the push plate seat 441 to push the rear pressure plate 431 away from the carton material surface, relieving the pressure force on the carton material. Then, the material storage station 11 is replenished manually or by a collaborative robot. After replenishment, the rubber-coated screw 4411 returns to its original position, and the rear pressure plate 431 is pulled back by the spring balancer 432, so that the rear pressure plate 431 is tightly pressed against the carton surface. The pressure plate rod 433 and the pressure plate seat 434 of the rear pressure plate 431 are equipped with limiters, so that the rear pressure plate 431 can only rotate within a certain angle range. With the help of the elastic element 435, the rear pressure plate 431 always remains parallel to the carton material surface when no other external force is applied. In this embodiment, the first pressing component 40, the first belt component 20, the second belt component 30, and the second pressing component 50 are respectively mounted on four mounting plates of the frame 10, each with an individually adjustable position via handwheels. This allows for the storage and supply of carton materials of different specifications. The upper box assembly 60 can also be height-adjusted via the longitudinal adjustment shaft 66 to accommodate cartons of different specifications. This embodiment features a compact and innovative design, making it highly suitable for use with smaller carton sealing machines. It improves work efficiency, reduces labor input, and lowers the labor intensity of operators.
