Description

Technical Field

[0001] The invention relates to the technical field of tobacco packaging, and in particular to a device for conveying cigarette groups and inner lining paper in parallel. Background Art

[0002] In the traditional liner paper wrapping technology, the liner paper and the cigarette group are wrapped in a horizontal and centered manner. The liner paper is short and the liner paper and the cigarette group can be transported to the packaging wheel independently. Figure 1 As shown, in the prior art, after the inner lining paper 100 in the limiting plate 300 is delivered into place, the inner lining paper 100 stops moving. At this time, the inner lining paper 100 and the cigarette group 200 are in a centered position, and then wait for the cigarette group 200 to be pushed to the left into the packaging wheel 400. When the cigarette group 200 is completely pushed into place, the inner lining paper 100 is also completely pushed into the packaging wheel 400 to complete the wrapping of the cigarette group. At the same time, the inner lining paper 100 is also pulled out from the limiting plate 300, so that the packaging wheel 400 can rotate counterclockwise with the inner lining paper 100 and the cigarette group 200 and complete the subsequent packaging action.

[0003] The fully open hard box packaging machine is a newly developed tobacco packaging machine. Its inner lining paper is longer, and the inner lining paper and the cigarette group are wrapped in a straight package rather than in a center package. The length above the limit plate 300 is greater than the length below the limit plate 300. Figure 2 In order to completely remove the inner liner 100 from the limiting plate 300, a large distance needs to be reserved between the packaging wheel 400 and the inner liner 100 and the cigarette group 200, so a device is needed to transport the cigarette group and the inner liner in parallel to the packaging wheel 400 for subsequent packaging. Summary of the invention

[0004] In view of the above-mentioned defects, the present invention provides a cigarette group and liner paper parallel conveying device suitable for a full-open hard box packaging machine, so as to solve the problems of the liner paper in the full-open cigarette package being too long and the difficulty in conveying and folding the liner paper caused by the asymmetric wrapping method.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 3 As shown, the present invention provides a device for conveying cigarette groups and inner lining paper in parallel. The device is arranged at the outlet of the limit plate 300. The limit plate 300 is provided with inner lining paper 100. The purpose is to meet the demand of synchronously conveying the inner lining paper 100 and the cigarette group (not shown) to the packaging wheel (not shown). It mainly includes a grooved rocker 5, a cigarette group conveying part 3, a first transmission part and a second transmission part. Among them, one end of the grooved rocker 5 is hinged to the fixed base 93, and the other end is a movable end. Its groove 51 faces the direction of the packaging wheel, and a movable part 42 is arranged inside, and a clamping block 4 is hinged on the movable part 42. Specifically, the movable part 42 is a roller, and can also be a slider or other structural form that can move in the groove; a movable part bracket 41 is hinged on the movable part 42, and the movable part bracket 41 is fixedly connected to the clamping block 4.

[0042] The cigarette group conveying unit 3 is arranged in the guide rail 8 and can move along the guide rail 8. The guide rail 8 is horizontally arranged between the unpacked cigarette group and the packaging wheel. The cigarette group conveying unit 3 can push the unpacked cigarette group and the liner paper to the packaging wheel along the guide rail 8, thereby completing the packaging of the cigarette group. At the same time, the cigarette group conveying unit 3 is hinged with the clamping block 4, and then hinged with the movable member 42. In a specific implementation, the cigarette group conveying unit 3 includes a mold box 33 for accommodating the cigarette group and a first connecting rod 31 and a second connecting rod 32 respectively fixedly mounted on the mold box 33. Both ends of the mold box 33 are open for the cigarette group to enter and exit. The first connecting rod 31 is hinged with the clamping block 4, and the second connecting rod 32 is hinged with the output end of the second transmission unit.

[0043] The output end of the first transmission part is hinged to the movable end of the grooved swing rod 5, and can drive the grooved swing rod 5 to move to a horizontal state, at which time the clamping block 4 clamps to the outlet end of the cigarette group conveying part 3 and remains unchanged. The output end of the second transmission part is hinged to the second connecting rod 32 of the cigarette group conveying part 3, and can drive the cigarette group conveying part 3 to move along the guide rail 8. Preferably, the first transmission part includes a first swing rod 1 and a first connecting rod 2, one end of the first swing rod 1 is hinged to the fixed first base 91, and is driven to rotate by a cam connected to the motor gear mechanism, and the other end is hinged to one end of the first connecting rod 2, and the other end of the first connecting rod 2 is hinged to the movable end of the grooved swing rod 5. Similarly, the second transmission part includes a second swing rod 6 and a second connecting rod 7, one end of the second swing rod 6 is hinged to the fixed second base 92, and is driven to rotate by a cam connected to the motor gear mechanism, and the other end is hinged to one end of the second connecting rod 7, and the other end of the second connecting rod 7 is hinged to the second connecting rod 32 of the cigarette group conveying part 3. To facilitate the operation of the device of the present invention, the first transmission part is arranged above the movable end of the grooved swing rod 5, and the second transmission part is arranged below the guide rail 8. In the initial state, the mold box 33 is located below the outlet of the limiting plate 300.

[0044] The working principle of the present invention is:

[0045] When the inner lining paper 100 is conveyed to the middle of the limiting plate 300 and in place, the first swing arm 1 swings downward, and drives the movable end of the grooved swing arm 5 to swing downward through the first connecting rod 2, and the grooved swing arm 5 drives the clamping block 4 to swing downward through the movable part 42 and the movable part bracket 41. When the grooved swing arm 5 is in a horizontal position, the first swing arm 1 stops swinging and keeps its position unchanged, and the clamping block 4 just clamps the inner lining paper 100 at the outlet end of the mold box 33. At this time, the cigarette group has been conveyed into the mold box 33, and the second swing arm 6 begins to swing toward the direction where the packaging wheel is located, and drives the mold box 33 to move horizontally along the guide rail 8 toward the location of the packaging wheel through the second connecting rod 7 and the second connecting rod 32. During the horizontal movement of the mold box 33, since the first swing arm 1 does not move, the clamping block 4 always clamps the inner lining paper 100 on the mold box 33 and conveys it in parallel with the cigarette group in the mold box 33. When the mold box 33 moves to the front end of the packaging wheel, the second swing arm 6 stops swinging, and the first swing arm 1 starts to swing upward, driving the clamping block 4 to swing upward, no longer clamping the liner paper 100 on the mold box 33 and leaving enough space between the mold box 33 so that the push-connection device can transport the cigarette group and the liner paper 100 to the packaging wheel. At this time, the first swing arm 1 stops swinging again. When the cigarette group and the liner paper are completely pushed into the packaging wheel, the first swing arm 1 continues to remain stationary, and the second swing arm 6 starts to swing away from the packaging wheel, driving the mold box 33 to move to the starting position and stop, so that one working cycle is completed, and the next group of cigarette groups and liner paper are transported.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
