Description

Technical Field

[0001] The utility model relates to a multi-station cigarette stacking and conveying device. Background Art

[0002] Cigarette cartons are formed by arranging and packaging multiple boxes of cigarettes, and after sorting, the cigarette cartons are transported by a conveying mechanism to a packaging mechanism for film packaging to form finished products. Cigarette cartons also have thin cigarette cartons and regular cigarette cartons according to the specifications of the cigarettes inside, and there are differences in thickness. If they are cross-stacked during stacking, they are more likely to tip over and affect subsequent packaging.

[0003] Generally, the combined stacking and packaging of thin cigarette groups and regular cigarettes requires the use of different stacking mechanisms and packaging conveyor lines, which is costly and does not meet the needs of the cigarette combinations required by merchants. A multi-station cigarette stacking and conveying device is needed to accommodate the simultaneous stacking and conveying of cigarettes of different specifications. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a multi-station cigarette stacking and conveying device, which is not only structurally reasonable, but also can simultaneously receive double-station cigarette stacking and conveying, and can also adapt to the conveying and stacking of cigarettes of different specifications.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a multi-station cigarette stacking and conveying device, including a packaging conveyor chain, a plurality of pushing plates for pushing and stacking cigarette strips are fixed at intervals on the packaging conveyor chain, and a straight push line for connecting the cigarette strips to complete the stacking and a stacking line for unfinished stacking are respectively arranged on both sides of the packaging conveyor chain. The stacking line includes a horizontal pushing platform, a vertical pushing platform and a sorting pushing platform connected to the cigarette strip conveyor belt. The horizontal pushing platform is arranged at the same level beside the packaging conveyor line, and a horizontal pushing plate is arranged on the upper end of the horizontal pushing platform and is pushed and moved back and forth by a horizontal linear motor. The vertical pushing platform is pushed and lifted by a lifting cylinder to connect with the sorting pushing platform to stack the cigarette strips layer by layer. A vertical pushing plate is arranged on the upper end of the vertical pushing platform and is pushed and moved back and forth by a longitudinal linear motor. The sorting pushing platform includes a sorting conveyor belt, and a sorting blocking plate that slides back and forth longitudinally is mounted above the sorting conveyor belt. A push plate is arranged above the sorting blocking plate, and the push plate is pushed and moved back and forth by the linear motor to push the cigarette strips to the vertical pushing platform.

[0006] Furthermore, the sorting blocking plate is in an inverted U shape, with both ends extending vertically downward and being pushed by a longitudinal cylinder to slide longitudinally, and its horizontal section is a transverse extension section.

[0007] Furthermore, frames supporting the sorting conveyor belt are arranged on both lateral sides thereof, and sliding holes are provided on the frames for the longitudinal sliding of vertical sections on both sides of the sorting blocking plate.

[0008] Furthermore, two opposing sensors are symmetrically arranged on the frame, and both of the opposing sensors are located between the pushing station of the push plate and the cigarette conveyor belt. The opposing heights of the opposing sensors are between the heights of the thin cigarette strips and the regular cigarette strips.

[0009] Furthermore, partitions for blocking cigarette strips are arranged on the side of the horizontal pushing platform away from the vertical pushing platform, between the vertical pushing platform and the packing conveyor chain, and on the side of the packing conveyor chain away from the horizontal pushing platform.

[0010] Furthermore, the straight push line includes a conveyor table docking with the stacking device, a baffle is provided at the longitudinal end of the conveyor table, and a straight push plate for laterally pushing the cigarette strips onto the packaging conveyor chain is provided on the surface of the conveyor table at this end. The side end of the straight push plate is pushed back and forth by a transverse cylinder, and the straight push plate and the transverse push plate are staggered along the longitudinal pushing direction of the packaging conveyor chain.

[0011] Furthermore, the bottom ends of the pushing plates are fixed to the packing conveyor chain via support columns. A receiving platform for receiving cigarette strips is provided above the packing conveyor chain at the same level as the horizontal pushing platform and the conveying platform. A slot is longitudinally provided on the receiving platform for the support columns to pass through and slide longitudinally.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the cigarette cartons stacking and conveying device can simultaneously receive cigarette cartons stacked and conveyed by the straight-push line and the stacking line, that is, it can receive double-station cigarette cartons stacking and conveying, and can adapt to the conveying and stacking of cigarette cartons of different specifications, which is more stable and efficient, and effectively saves the processing cost of stacking and conveying before packaging.

[0019] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0020] like Figures 1 to 4 As shown, a multi-station cigarette stacking and conveying device comprises a packing conveyor chain 1, on which a plurality of push plates 3 for pushing and stacking cigarette strips 2 are fixedly arranged at intervals, and a straight push line 4 for connecting cigarette strips to complete stacking and a stacking line 5 for unfinished stacking are respectively arranged on both sides of the packing conveyor chain, and the stacking line comprises a horizontal push table 6, a vertical push table 7 and a sorting push table 8 for connecting to the cigarette strip conveyor belt 30, the horizontal push table is arranged at the same level beside the packing conveyor line, a horizontal push plate 9 is arranged on the upper end of the horizontal push table and is pushed back and forth by a horizontal linear motor 10, and the vertical push plate 9 is arranged on the upper end of the horizontal push table and is pushed back and forth by a horizontal linear motor 10. The platform is lifted and lowered by a lifting cylinder 11 to dock with the sorting and pushing platform to stack the cigarette strips layer by layer. A longitudinal pushing plate 12 is provided at the upper end of the longitudinal pushing platform and is pushed back and forth by a longitudinal linear motor 13. The sorting and pushing platform includes a sorting conveyor belt 14, above which is provided a longitudinal reciprocating sorting blocking plate 15, above which is provided a push plate 16, the height of the sorting blocking plate is lower than the lowest point of the push plate, that is, while ensuring that the cigarette strips can be blocked, the push plate does not affect the pushing of the cigarette strips by the push plate, and the push plate is pushed back and forth by the linear motor 17 to push the cigarette strips to the longitudinal pushing platform.

[0021] In the embodiment of the utility model, the sorting blocking plate is in an inverted U shape, with both ends extending vertically downward and being pushed by the longitudinal cylinder 18 to slide longitudinally, and its horizontal section is a transverse extension section.

[0022] In the embodiment of the utility model, frames 19 supporting the sorting conveyor belt are arranged on both lateral sides thereof, and sliding holes 20 are provided on the frames for the longitudinal sliding of the vertical sections on both sides of the sorting blocking plate.

[0023] In an embodiment of the utility model, two opposing sensors 21 are laterally symmetrically arranged on the frame, and both of the opposing sensors are located between the pushing station of the push plate and the cigarette conveyor belt. The opposing heights of the opposing sensors are located between the heights of thin cigarette strips and regular cigarette strips, and the opposing sensors are electrically connected to the sorting conveyor belt.

[0024] In the embodiment of the utility model, partitions 22 for blocking cigarette strips are arranged on the side of the horizontal pushing platform away from the vertical pushing platform, between the vertical pushing platform and the packing conveyor chain, and on the side of the packing conveyor chain away from the horizontal pushing platform.

[0025] In an embodiment of the utility model, the straight push line includes a conveyor table 23 for docking with the stacking device, a baffle 24 is provided at the longitudinal end of the conveyor table, and a straight push plate 25 for laterally pushing the cigarette strips onto the packaging conveyor chain is provided on the surface of the conveyor table at this end. The side end of the straight push plate is pushed back and forth by a transverse cylinder 26, and the straight push plate and the transverse push plate are staggered along the longitudinal pushing direction of the packaging conveyor chain.

[0026] In the embodiment of the utility model, the bottom end of the pushing plate is fixed on the packing conveyor chain via a support column 27. A receiving platform 28 for receiving cigarette strips is arranged above the packing conveyor chain at the same level as the horizontal pushing platform and the conveying platform. A slot hole 29 is longitudinally opened on the receiving platform for the support column to pass through and slide longitudinally.

[0027] The working principle of the embodiment of the utility model is as follows: first, the straight push line and the stacking line can work at the same time. When the straight push line is working, the stacked cigarette strips of the same specification are transported to the end of the conveying table, and are pushed to the receiving table through the horizontal cylinder, and then pushed to the next station between the two pushing plates through the packaging conveyor chain, but this station is the pushing station of the horizontal pushing table, that is, it is necessary to push another station, that is, each time a group of cigarette strips of the same specification is pushed, the pushing plate needs to push two stations. When the stacking line is working, generally each group of thin cigarette strips is pushed into place first. At this time, the sorting blocking plate is longitudinally moved to the side away from the shooting sensor to stack more correct cigarette strips at the pushing station. After it is in place, the sorting conveyor belt stops and the linear motor The bottom layer of cigarette strips is pushed horizontally onto the vertical pushing table. At this time, the vertical pushing table is lowered by the lifting cylinder to the height of one cigarette strip to ensure that the next push will be as the second layer. Stacks are formed by reciprocating in sequence. If the last shooting sensor senses conventional cigarette strips, the sorting conveyor belt will stop until the thin cigarette strips are pushed horizontally and then the conventional cigarette strips are released as the top layer. The blocking position of the sorting blocking plate is selected according to the quantity to facilitate horizontal pushing. Setting conventional cigarette strips as the top layer can effectively avoid the situation where stacking fails due to unevenness. When the surface of the vertical pushing table drops to the same level as the horizontal pushing table, the stacked cigarette strips can be pushed to the horizontal pushing table through the vertical pushing plate, and then pushed to the receiving table through the horizontal pushing plate for transportation to the packaging station.

[0028] The utility model is not limited to the above-mentioned best implementation mode. Anyone can derive other various forms of multi-station cigarette stacking and conveying devices under the inspiration of the utility model. All equivalent changes and modifications made according to the scope of the patent application of the utility model shall fall within the scope of the utility model.
