Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a cigarette pack stacking device. Background Art

[0002] The cigarette packaging process includes cigarette pack packaging and carton packaging. After the cigarettes are filled into cigarette packs and packaged by the small box transparent paper packaging machine, they are transported to the carton packaging equipment through the cigarette pack channel of the transfer device. After being stacked and arranged, they are loaded into cartons to obtain carton cigarettes.

[0003] Currently, the most common carton of cigarettes contains ten cigarette packs, which are stacked in the carton in the form of five packs horizontally and two rows up and down. Correspondingly, the existing automated filling equipment also stacks the cigarette packs into 2×5 cigarette pack groups and loads them into the carton packaging at one time. In order to improve the stacking efficiency, some existing technologies have set a stacking mechanism upstream of the carton packaging equipment, which is generally composed of a cigarette pack horizontal channel, a cigarette pack stacking device, a double cigarette pack pushing device, etc. The stacking mechanism can transform the originally single-layered cigarette packs into double-layer stacking units and then transport them to the carton packaging equipment, so that the subsequent cigarette pack arrangement is more efficient, which facilitates the carton packaging equipment to smoothly complete the cigarette pack grouping action. The utility model patent with patent announcement number CN210364571U discloses a cigarette pack stacking structure for a transparent paper packaging machine, which mainly includes a lifting mechanism, a baffle and a movable block. The lifting mechanism first lifts the first cigarette pack between the two baffles and places it on the movable block, and then lifts the second cigarette pack between the two baffles and places it on the movable block. At this time, the first cigarette pack is lifted by the second cigarette pack, and the first cigarette pack and the second cigarette pack are stacked up and down to form a stacking unit, waiting for the push-out mechanism to push the stacking unit to the transfer mechanism. Although the technical solution disclosed in the above patent can stack cigarette packs, the positioning accuracy of the cigarette packs before stacking the cigarette packs is not good, and it cannot ensure that the cigarette packs enter the stacking device in the best orientation, resulting in the cigarette packs being easily squeezed during the stacking process, which in turn causes the outer packaging of the cigarette packs to be damaged and cigarettes to be stuck, which is not conducive to the transportation of cigarette packs and the protection of the outer packaging of cigarette packs. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a cigarette pack stacking device, which can enable the cigarette packs to enter the stacking mechanism with high positioning accuracy, prevent cigarette jams or damage to the outer packaging of the cigarette packs, and improve the stability of automated production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cigarette pack stacking device comprises an introduction mechanism and a stacking mechanism; the introduction mechanism comprises a mounting base and two guide assemblies fixed above the mounting base and arranged in a separation manner, an empty separation area is formed between the two guide assemblies, the guide assembly comprises a support plate and a cover plate arranged in parallel, a cigarette pack channel is formed between the support plate and the cover plate, an edge sealing member is arranged on the outer side of the cigarette pack channel, the inner side of the cigarette pack channel is communicated with the separation area, the cigarette pack channels of the two guide assemblies are arranged in parallel and have corresponding heights; the stacking mechanism comprises two limiting side plates and two positioning members corresponding to the limiting side plates one by one, a lifting channel is formed between the two limiting side plates, a lifting plate connected to a motor is arranged at the lower end of the lifting channel, and the positioning member is connected to an elastic mechanism that can make the positioning member protrude or retract relative to the inner side surface of the limiting side plate.

[0007] The utility model positions the cigarette pack through two guide components, so that the cigarette pack is conveyed to the stacking mechanism in the best orientation and forms a stacking unit. Each guide component limits the side of the cigarette pack through the rectangular cavity formed by the support plate, the cover plate and the edge sealing member, so that the cigarette pack is accurately positioned. The partition area left between the two guide components makes the middle of the cigarette pack suspended when passing through the cigarette pack channel, which is conducive to releasing pressure to avoid the compression and deformation of the cigarette pack. It is also conducive to observing the transportation of the cigarette pack in the cigarette pack channel. When an unexpected situation occurs and causes cigarette jam, the cigarette pack can be manually adjusted through the partition area. The working principle of the utility model is as follows: First, the first cigarette pack is positioned through the cigarette pack conveying channel and reaches the lifting plate under the push of the subsequent cigarette pack. The lifting plate lifts the first cigarette pack. During the lifting process, the cigarette pack pushes the positioning member to retract it. When the first cigarette pack passes over the positioning member, the positioning member resumes the protruding state. At this time, the lifting plate retreats to the bottom, and the first cigarette pack is suspended and placed on the positioning member. Then the second cigarette pack repeats the above process, and the two cigarette packs can be stacked and placed above the positioning member.

[0008] Furthermore, the cigarette pack stacking device further comprises a pushing mechanism, the pushing mechanism comprising a pushing member and a power member connected to the pushing member, the pushing member being arranged at a position higher than the positioning member. The pushing mechanism is used to transfer the stacking unit from the stacking mechanism to a downstream conveying mechanism, so that the stacking unit is further stacked downstream to form a cigarette pack group.

[0009] Furthermore, the introduction end of the support plate forms a guide portion, which includes a first guide slope located on the upper side of the support plate and a second guide slope located on the lower side of the support plate. The first guide slope and the second guide slope are close to each other so that the thickness of the guide portion gradually decreases in the end direction.

[0010] Furthermore, a positioning guide plane is formed on the upper side of the positioning member, and the elastic mechanism can maintain the positioning guide plane in a state perpendicular to the inner side surface of the limiting side plate. The positioning guide plane enables the stacking unit to be transferred to the downstream by the pushing mechanism in a horizontal direction, which is conducive to improving the subsequent stacking accuracy.

[0011] Furthermore, the limiting side plate is provided with a mounting opening penetrating the plate body, and the positioning member is arranged at the mounting opening.

[0012] Furthermore, the elastic mechanism is composed of a spring, a torsion spring or a magnetic device.

[0013] Furthermore, the guide assembly is connected to the mounting base via a strip hole, and the length direction of the strip hole is perpendicular to the extension direction of the cigarette pack conveying channel. The fixed position of the guide assembly on the mounting base can be changed through the strip hole, thereby changing the distance between the two guide assemblies, thereby adapting to cigarette packs of different sizes, and expanding the application range of the device.

[0014] Furthermore, the lower side of the lifting plate is connected to an abutment block flush with the side of the lifting plate, and the height of the abutment block is not less than the height difference between the support plate and the positioning member. The abutment block is used to prevent the second cigarette pack from getting stuck under the lifting plate when the first cigarette pack is lifted.

[0015] Furthermore, the cigarette pack stacking device further comprises a pack stacking conveyor belt, the upper surface of which is no higher than the upper edge of the positioning member. The pack stacking conveyor belt is used to convey the pack stacking unit to the downstream carton packaging equipment.

[0016] Furthermore, the inner side of the cover plate forms an extension extending horizontally toward the partition area, the end of the extension is vertically connected to a limiting end plate, the extension is formed near the lifting channel, and a gap is left between the limiting plates connected to the two cover plates. The limiting plate is used to limit the end position of the cigarette pack during the lifting process and placed on the positioning member to prevent the cigarette pack from falling from the lifting plate or the positioning member.

[0017] The application of the utility model can achieve the following beneficial effects:

[0018] 1. The utility model uses an introduction mechanism to position cigarette packs with high precision, so that they are transferred to the lifting plate in the best orientation, thereby improving the stacking accuracy of subsequent stacking units, making the subsequent cigarette pack arrangement more efficient, and facilitating the strip box packaging equipment to smoothly complete the cigarette pack grouping action.

[0019] 2. The separation area left between the two guide components of the utility model allows the middle of the cigarette pack to be suspended when passing through the cigarette pack channel, which is conducive to releasing pressure to prevent the cigarette pack from being compressed and deformed. It is also conducive to observing the transportation conditions of the cigarette pack in the cigarette pack channel. When an unexpected situation occurs and causes cigarette jamming, the cigarette pack can be manually adjusted through the separation area.

[0020] 3. In some embodiments, the distance between the two guide components can be adjusted to accommodate cigarette packages of various specifications or different conveying methods, thereby increasing the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2This embodiment provides a cigarette pack stacking device, which includes an introduction mechanism 1 for positioning and transferring cigarette packs and a stacking mechanism 2 for receiving cigarette packs from the introduction mechanism and stacking the cigarette packs into stacking units.

[0030] The introduction mechanism includes two guide components 11, and a controlled partition area 13 is formed between the two guide components. The guide components include a support plate 111 and a cover plate 112 which are horizontally arranged when in use. The positions of the support plate and the cover plate correspond to each other up and down, and a cigarette pack conveying channel 114 is formed between the support plate and the cover plate. On the side away from the partition area, the guide components are provided with an edge sealing member 113, and the edge sealing member makes the outer side edge of the cigarette pack conveying channel in a closed state, and the inner side edge of the cigarette pack conveying channel communicates with the partition area. The cigarette pack conveying channels of the two guide components are arranged in parallel and on the same plane, so that the two side edges of the cigarette pack can each cooperate with a cigarette pack conveying channel, and at the same time the middle part of the cigarette pack is exposed from the partition area, and the power for the cigarette pack to pass through the cigarette pack conveying channel comes from the driving force of the cigarette pack at the rear. Each guide assembly is connected to a mounting block 12 below, and the mounting block is used to fix the guide assembly to the mounting base of the device. The mounting block is provided with a strip hole 121, and the length direction of the strip hole is perpendicular to the extension direction of the cigarette pack conveying channel, so that the mounting block can change its own fixed position on the mounting base, and then adjust the distance between the two guide assemblies to adapt to cigarette packs of different specifications or different conveying methods. The inner side edge of the cover plate forms an extension portion 1121 extending toward the partition area, and the end of the extension portion is vertically connected to a limiting end plate 1122, which is used to limit the end position of the cigarette pack during the subsequent lifting and stacking process to prevent the cigarette pack from falling. The limiting end plate is parallel to the extension direction of the cigarette pack conveying channel, and a gap is left between the limiting end plates in the two guide assemblies to facilitate the adjustment of the distance between the guide assemblies. A guide portion 1111 is formed at the inlet end of the support plate, and the guide portion includes a first guide slope and a second guide slope respectively formed on the upper and lower sides of the support plate. The first guide slope and the second guide slope are close to each other, so that the thickness of the guide portion gradually decreases in the end direction to facilitate receiving the cigarette pack from upstream.

[0031] The stacking mechanism includes two limiting side plates 21 arranged in parallel and symmetrically, a lifting channel 23 is formed between the two limiting side plates, a lifting plate 22 connected to a motor is arranged at the bottom of the lifting channel, the position of the lifting plate corresponds to the end of the cigarette pack conveying channel, and is used to receive the cigarette pack and lift the cigarette pack upward through the lifting channel, a mounting opening is arranged on the limiting side plate, a positioning member 24 is movably installed at the mounting opening, the positioning member is connected to the elastic mechanism, so that the positioning member can protrude or retract relative to the inner side surface of the limiting side plate through the mounting opening, specifically, the positioning member includes a mounting shaft, and the mounting shaft is connected to the torsion spring Then, the torsion spring applies a preset elastic force to the mounting shaft, so that the positioning member protrudes relative to the inner side surface of the limiting side plate in a natural state. When the lifting plate carrying the cigarette pack is lifted upward, the cigarette pack contacts the positioning member and causes the positioning member to be retracted. When the cigarette pack passes over the positioning member, the positioning member protrudes again. At this time, the lifting plate retreats to the lower side, and the cigarette pack can be placed above the positioning member in the air. By repeating the above steps, multiple cigarette packs can be stacked and placed above the positioning member, waiting for subsequent transportation. In order to avoid the second cigarette pack from being stuck under the lifting plate when the first cigarette pack is lifted, an abutment block 25 is connected to the bottom of the lifting plate in this embodiment, and the abutment block is flush with the edge of the lifting plate.

[0032] Example 2

[0033] Reference Figures 3-5 Another embodiment of the utility model provides a cigarette pack stacking device. On the basis of embodiment 1, the device further provides a push mechanism 3 and a stacking conveyor belt 4. The push mechanism 3 is arranged above the stacking mechanism. The push mechanism includes a push member 31 and a power member 32 connected to the push member. In the initial state, the push member is arranged in the upstream direction of the lifting channel, and the setting height of the push member is higher than the positioning member. Driven by the power member, the push member can move horizontally to the stacking conveyor belt located downstream of the lifting channel. When a stacking unit is placed on the positioning member, the push member can transfer the stacking unit to the stacking conveyor belt. In order to facilitate receiving the stacking unit, the upper surface of the stacking conveyor belt should be set flush or slightly lower than the upper edge of the positioning member in the natural state, so that the cigarette pack will not collide with the end of the stacking conveyor belt. At the same time, in order to ensure the stability and accuracy of the horizontal transportation of the cigarette pack, the positioning member is provided with a positioning guide surface 241. When the positioning member is in the natural state, the positioning guide is in the horizontal direction and perpendicular to the limiting side plate.
