Description

Technical Field

[0001] The invention belongs to the technical field of tobacco production equipment, and particularly relates to a method for unloading a sheet cigarette box. Background Art

[0002] During the cigarette production process, tobacco leaves harvested from the tobacco fields undergo a primary curing process to form raw tobacco. The raw tobacco is then threshed and redried at the redrying plant, where it is processed into tobacco strips. The strips undergo aging before they can be used in cigarette production. After threshing and redrying at the redrying plant, the strips are packed and shipped to cigarette manufacturers. Cigarette manufacturers use trucks to unload the strips and transport them to aging warehouses for aging and storage. Because the strips are transported in full truckloads, they are tightly packed together, leaving no gaps between them. When manually unloading the strip boxes, clamps must be forcibly inserted between the two strip boxes. This can easily damage the boxes, exposing and scattering the tobacco, impacting the aging and storage quality of the strips. Furthermore, unloading the strip boxes is inconvenient and inefficient. Therefore, to reduce the impact of damage to the strip boxes during unloading on the aging and storage quality of the strips and improve cigarette loading and unloading efficiency, it is necessary to improve the existing strip unloading structure. Summary of the Invention

[0003] The technical problem solved by the present invention is to provide a method for unloading a sheet cigarette box, by arranging pushing devices with buffer parts fixed on the telescopic ends of the left and right clamps, before the sheet cigarette box is clamped, the pushing device on the non-smoke box side of the first sheet cigarette box close to the side pushes the first sheet cigarette box to an inclined state, and then the left and right clamps clamp the first sheet cigarette box for unloading, which solves the problem of damaging the sheet cigarette box due to forced insertion of the left or right clamp during unloading, ensures that the sheet cigarette box is intact, eliminates the quality risk of exposure and scattering of tobacco sheets due to damage to the sheet cigarette box, improves the aging and storage quality of the tobacco sheets, and at the same time improves the unloading efficiency of the sheet cigarette box, and can be promoted and applied in the sheet cigarette field of the tobacco industry.

[0004] The technical solution adopted by the present invention is: a method for unloading a sheet cigarette box, including a holding car, wherein the outer walls of the left and right holding clamps of the holding car are both provided with pushing devices, and a left operating lever for controlling the extension and retraction of the pushing device on the outer wall of the left holding clamp and a right operating lever for controlling the extension and retraction of the pushing device on the outer wall of the right holding clamp are both arranged in the operating room of the holding car, and the retractable end of the pushing device is provided with a buffer part that contacts the sheet cigarette box during pushing.

[0005] Among them, the pushing device includes a pushing hydraulic cylinder and a pusher. The pushing hydraulic cylinder is fixed on the outer wall of the left clamp and the right clamp, and the piston rod of the pushing hydraulic cylinder is arranged toward the opposite side of the car holding operating room. One end of the pusher is fixedly connected to the end of the piston rod of the pushing hydraulic cylinder, and the buffer is fixed to the other end of the pusher. The pusher is driven by the pushing hydraulic cylinder to extend and push the cigarette box to the same side of the pushing plate and move backward to an inclined state.

[0006] Furthermore, the pusher is a push plate, and the push plate is arranged parallel to the left clamp and the right clamp.

[0007] Furthermore, the buffer is a rubber strip, the cross-sectional shape and size of the rubber strip at the connection side with the pushing device are the same as the shape and size of the telescopic end face of the pushing device, and the outer end of the rubber strip is an arc-shaped structure.

[0008] The method for unloading a sheet cigarette box comprises the following steps:

[0009] 1) Move the holding car to the front of the first strip cigarette box at the side. At this position, there is a cigarette box on one side of the first strip cigarette box and no cigarette box on the other side. Adjust the left and right holding clamps so that the distance between the two pushing devices is less than the length of the front box wall of the first strip cigarette box. At this time, the left holding clamp or the right holding clamp on the same side as the non-smoking side of the first strip cigarette box is located in front of the first strip cigarette box.

[0010] 2) The piston rod of the pushing hydraulic cylinder on the outer wall of the left or right holding clamp is controlled to extend by the left operating lever or the right operating lever. After the pushing hydraulic cylinder piston rod drives the pushing plate to be pushed out, the rubber strip at the outer end of the pushing plate contacts the front wall of the non-smoking side of the first sheet cigarette box. As the pushing hydraulic cylinder piston rod continues to extend, the non-smoking side of the first sheet cigarette box is pushed backward until the first sheet cigarette box is tilted. At this time, a gap is formed between the first sheet cigarette box and the adjacent sheet cigarette box for the left or right holding clamp to be inserted;

[0011] 3) Use the left or right operating lever to control the piston rod of the push hydraulic cylinder to reset, at which time the extended push plate is retracted;

[0012] 4) Control the left and right clamps so that they are located on both sides of the first sheet cigarette box, and adjust the distance between the left and right clamps until the first sheet cigarette box is clamped before unloading;

[0013] 5) Repeat the above process until all the cigarette boxes on the truck are unloaded.

[0014] The advantages of the present invention compared with the prior art are:

[0015] 1. This technical solution provides a pushing device with a buffer fixed to the end of the telescopic end on the outer wall of the left and right clamps. Before the sheet cigarette box is clamped, the pushing device on the non-smoking side of the first sheet cigarette box near the edge pushes the first sheet cigarette box to an inclined state, thereby forming a gap between the first sheet cigarette box and the adjacent sheet cigarette box, thereby facilitating the unobstructed insertion of the left or right clamp.

[0016] 2. This technical solution fixes a rubber strip on the outer end of the push plate, and designs the contact end of the rubber strip and the sheet cigarette box into an arc-shaped structure. The structure of the rubber strip contacting the sheet cigarette box during pushing can greatly reduce the damage to the sheet cigarette box during pushing, thereby ensuring the quality of the sheet cigarettes in the sheet cigarette box during pushing;

[0017] 3. This technical solution solves the problem of damaged tobacco strip boxes due to forced insertion of left or right clamps during unloading, ensuring the integrity of tobacco strip boxes, eliminating the quality risk of tobacco strips being exposed or scattered due to damaged tobacco strip boxes, and improving the aging and storage quality of tobacco strips.

[0018] 4. This technical solution has an ingenious structural design, strong practicality and high reliability, which makes it easier for unloading personnel to unload cigarette boxes and improves the efficiency of cigarette loading and unloading. It can be promoted and applied in the field of cigarette sheets in the tobacco industry. BRIEF DESCRIPTION OF THE DRAWINGS

In the absence of further limitations, the phrase "comprising a..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising the elements.

[0029] Unloading method of sheet cigarette box, such as Figure 1-4 As shown, it includes a holding car 1, and the outer walls of the left holding clamp 2 and the right holding clamp 3 of the holding car 1 are both provided with pushing devices, and the left operating lever 4 for controlling the extension and retraction of the pushing device on the outer wall of the left holding clamp 2 and the right operating lever 5 for controlling the extension and retraction of the pushing device on the outer wall of the right holding clamp 3 are both provided in the operating room of the holding car 1, and the left operating lever 4 and the right operating lever 5 are respectively used to control the control valve to control the oil pressure flow and the stroke of the pushing device on the corresponding side. The telescopic end of the pushing device is provided with a buffer member that contacts the cigarette box during pushing.

[0030] like Figure 1-3 As shown, the specific structure of the pushing device is as follows: the pushing device includes a pushing hydraulic cylinder 6 and a pusher. The outer walls of the left clamp 2 and the right clamp 3 are fixed with a pushing hydraulic cylinder 6, and the piston rod of the pushing hydraulic cylinder 6 is arranged toward the opposite side of the operating room of the holding vehicle 1. One end of the pusher is fixedly connected to the end of the piston rod of the pushing hydraulic cylinder 6. The buffer is fixed to the other end of the pusher, and the pusher is driven by the pushing hydraulic cylinder 6 to extend and push the cigarette box to the same side of the pushing plate 7 and move backward to an inclined state. The pusher is a push plate 7, which is arranged parallel to the left clamp 2 and the right clamp 3. During installation, it is necessary to ensure that there is a certain safety distance between the left clamp 2 and the push plate 7 thereon, and between the right clamp 3 and the push plate 7 thereon, to ensure that the push plate 7 does not interfere with the outer wall of the clamp when moving, and to ensure that the push plate 7 can extend and retract smoothly; wherein, the stroke of the push hydraulic cylinder 6 on the left clamp 2 is controlled by the left operating lever 4, and the stroke of the push hydraulic cylinder 6 on the right clamp 3 is controlled by the right operating lever 5.

[0031] like Figure 4As shown, the buffer is specifically as follows: the buffer is a rubber strip 8, the cross-sectional shape and size of the rubber strip 8 on the side connected to the pushing device are the same as the shape and size of the end face of the telescopic end of the pushing device, and the outer end of the rubber strip 8 is an arc-shaped structure; in the above structure, by fixing the rubber strip 8 at the outer end of the pushing plate 7, and designing the contact end of the rubber strip 8 and the sheet cigarette box to be an arc-shaped structure, the structure in which the rubber strip 8 contacts the sheet cigarette box during pushing plays a buffering role, which can greatly reduce the damage to the sheet cigarette box during pushing, and ensure the quality of the sheet cigarettes in the sheet cigarette box during pushing.

[0032] Unloading method of sheet cigarette box, such as Figure 5-8 As shown, the following steps are included:

[0033] 1) Move the holding car 1 to the front of the first sheet cigarette box 9 at the side. At this position, there is a cigarette box on one side of the first sheet cigarette box 9 and no cigarette box on the other side. Adjust the left holding clamp 2 and the right holding clamp 3 so that the distance between the two pushing devices is less than the length of the front box wall of the first sheet cigarette box 9. At this time, the left holding clamp 2 on the same side as the side without cigarette box of the first sheet cigarette box 9 is located in front of the first sheet cigarette box 9. The specific position relationship is as follows: Figure 5 As shown;

[0034] 2) The left operating lever 4 is used to control the extension of the piston rod of the pushing hydraulic cylinder 6 on the outer wall of the left holding clamp 2. After the piston rod of the pushing hydraulic cylinder 6 drives the pushing plate 7 to be pushed out, the rubber strip 8 at the outer end of the pushing plate 7 contacts the front box wall of the non-smoking side of the first sheet cigarette box 9. As the piston rod of the pushing hydraulic cylinder 6 continues to extend, the non-smoking side of the first sheet cigarette box 9 is pushed backward until the first sheet cigarette box 9 is tilted. At this time, a gap is formed between the first sheet cigarette box 9 and the adjacent sheet cigarette box for the right holding clamp 3 to be inserted. The specific position relationship is shown as follows: Figure 6 As shown;

[0035] 3) The left operating lever 4 controls the piston rod of the push cylinder 6 to reset. At this time, the extended push plate 7 is retracted. Figure 7 As shown;

[0036] 4) Control the left clamp 2 and the right clamp 3 so that they are located on both sides of the first sheet cigarette box 9. At this time, the right clamp 3 can be inserted into the gap between the first sheet cigarette box 9 and the adjacent sheet cigarette box without any obstacles. Adjust the distance between the left clamp 2 and the right clamp 3 until the first sheet cigarette box 9 is clamped and unloaded. The clamp is fixed as shown in the figure. Figure 8 As shown;

[0037] 5) Repeat the above process until all the cigarette boxes on the truck are unloaded.

[0038] This technical solution is to provide a pushing device with a buffer piece fixed at the telescopic end on the outer wall of the left holding clamp 2 and the outer wall of the right holding clamp 3. Before the sheet cigarette box is clamped, the pushing device on the non-smoking side of the first sheet cigarette box 9 close to the side pushes the first sheet cigarette box 9 to a tilted state, so that a gap is formed between the first sheet cigarette box 9 and the adjacent sheet cigarette box, thereby facilitating the unimpeded insertion of the left holding clamp 2 or the right holding clamp 3, solving the problem of damaging the sheet cigarette box due to forced insertion of the left holding clamp 2 or the right holding clamp 3 during unloading, ensuring the integrity of the sheet cigarette box, eliminating the quality risk of exposure and scattering of tobacco sheets due to damage to the sheet cigarette box, and improving the aging and storage quality of the tobacco sheets; the structural design is ingenious, practical and reliable, which is convenient for unloading personnel to carry out sheet cigarette box unloading operations, improves the efficiency of cigarette loading and unloading, and can be promoted and applied in the tobacco industry sheet cigarette field.
