In some embodiments of the cut tobacco packing system of the present invention, as shown in fig. 1, the system includes a first production line 10, a second production line 20, a feeding device 30 and a uncapping device 40, wherein the first production line 10 and the second production line 20 are arranged in parallel, and a first station 11 and a second station 12 located downstream of the first station 11 are disposed on each of the first production line 10 and the second production line 20.
The feeding device 30 is configured to reciprocate between the first line 10 and the second line 20 to alternately perform the operations of loading the cut tobacco into the empty boxes 50 at the first station 11 of the first line 10 and at the first station 11 of the second line 20, respectively.
The feeding device 30 first feeds the cut tobacco into the empty boxes 50 at the first station 11 of the first production line 10 and then moves to the first station 11 of the second production line 20 to feed the cut tobacco into the empty boxes 50 located at the first station 11 of the second production line 20. The feeding device 30 reciprocates between the first station 11 of the first line 10 and the first station 11 of the second line 20.
Ideally, when the feeding device 30 completes the operation of loading the empty box 50 with the cut tobacco at the first station 11 of the first production line 10 (or the second production line 20) and moves to the first station 11 of the second production line 20 (or the first production line 10), the box 50 above the first station 11 of the second production line 20 is in place, and the feeding device 30 can immediately load the cut tobacco into the empty box 50 located at the first station 11 of the second production line 20 (or the first production line 10) without waiting. Therefore, the actions of the feeding device 30 can be connected without stopping for waiting, and the feeding device can be always in a working state, so that the boxing efficiency is improved.
The capping and uncapping devices 40 are arranged on the first production line 10 and the second production line 20, and the capping and uncapping devices 40 are configured to reciprocate between the first station 11 and the second station 12 of the respective production lines so as to remove and convey the box cover 60 on the box body 50 of the first station 11 to the second station 12 and to replace the box cover 60 on the box body 50 after the box body 50 reaches the second station 12.
In the embodiment of the invention, each production line is provided with two stations, the feeding device 30 finishes the operation of loading the cut tobacco into the empty box 50 at the first station 11, and the cover adding and removing device 40 finishes the operation of replacing the removed box cover 60 into the box 50 at the second station 12, so that after the cut tobacco is loaded into the box 50, the box 50 can be moved to the second station 12 to replace the box 50, so as to empty the first station 11, and the next empty box 50 can enter the first station 11 by utilizing the time that the previous box 50 is covered at the second station 12, thereby reducing the waiting time and effectively improving the packing efficiency.
As shown in fig. 2 to 7, in some embodiments, the capping and uncapping device 40 includes a supporting frame 41, a movable member 42, a clamping device 43, and a driving device 44, the supporting frame 41 is disposed above the first station 11 and the second station 12, the movable member 42 is movably mounted on the supporting frame 41, the clamping device 43 is connected with the movable member 42 and configured to clamp or release the cap 60, and the driving device 44 is mounted on the supporting frame 41 and is used for driving the movable member 42 to move relative to the supporting frame 41.
When the cover needs to be removed, the driving device 44 drives the movable piece 42 to move to the position above the first station 11, the movable piece 42 drives the clamping device 43 to also move to the position above the first station 11, the clamping device 43 acts to clamp the cover 60 on the top of the box body 50, then the driving device 44 drives the movable piece 42 to return to the second station 12, and the movable piece 42 drives the clamping device 43 and carries the cover 60 to return to the second station 12, so that the cover removing operation is completed. When the box 50 is filled with cut tobacco and the box is transported to the second station 12, the gripping device 43 is actuated again to release the lid 60, replacing the lid 60 on top of the box 50 and completing the capping operation.
The supporting frame 41 is disposed above the first station 11 and the second station 12, i.e. on the moving path of the box 50, but not on the side of the first station 11 and the second station 12, so that the box cover 60 can be brought back to the second station 12 after the cover is taken, and the capping operation can be performed at the second station 12.
The gripping device 43 comprises gripping jaws which can grip the cover 60 and carry the cover 60 in motion. In other embodiments, the holding device 43 may be replaced by a suction cup or a hook.

As shown in fig. 2, a power source 45 is mounted on the supporting frame 41, and the power source may be hydraulic oil, air source or power source, and supplies hydraulic oil, high-pressure gas or electric power to the clamping device 43 to drive the clamping device 43 to move.
In some embodiments, the gripping device 43 is vertically liftable up and down. Upon reaching the top of the box 50, the gripping device 43 is lowered so as to reach the level of the cover 60. After clamping the cover 60, the clamping device 43 is lifted and then moved to the second station 12 along with the movable member 42. The clamping device 43 can be lifted up and down, so that the box cover 60 can be prevented from interfering with other objects.
In some embodiments, the adding and removing device 40 further includes a storage device for temporarily storing the cover 60. After the cover 60 clamped by the clamping device 43 reaches the second station 12, the cover 60 can be temporarily stored on the storage device to release the clamping force applied by the clamping device 43, thereby saving energy.
The storage device may include two storage rods disposed on the support frame 41, and the cover 60 may be placed on the two storage rods for temporary storage.
As shown in fig. 2 to 4, in some embodiments, the supporting frame 41 includes a first supporting rod 411, a second supporting rod 412 and a third supporting rod 413 connected between the first supporting rod 411 and the second supporting rod 412, the first supporting rod 411 is located on a side of the center of the first station 11 away from the second station 12, the second supporting rod 412 is located on a side of the center of the second station 12 away from the first station 11, and the movable member 42 is movably mounted on the third supporting rod 413.
In the above embodiment, the first support rod 411 is located on the side of the center of the first station 11 away from the second station 12, the second support rod 412 is located on the side of the center of the second station 12 away from the first station 11, and the movable member 42 is movably mounted on the third support rod 413, so that the moving stroke of the movable member 42 at least includes the distance from the center of the first station 11 to the center of the second station 12, without adding a cantilever arm in order to allow the movable member 42 to reach the first station 11 or the second station 12.
In some embodiments, as shown in fig. 3, the first supporting rod 411 is located on a side of the first station 11 away from the second station 12, and the second supporting rod 412 is located on a side of the second station 12 away from the first station 11, and the side is away from the first station 11, that is, the distance between the first supporting rod 411 and the second supporting rod 412 is not less than the maximum distance between the first station 11 and the second station 12, and the length of the supporting frame 41 covers the total length of the first station 11 and the second station 12, so as to ensure that the movable member 42 can reach the first station 11 or the second station 12 without adding other intermediate members, such as a cantilever and the like; and also. The support frame 41 has a longer length, which can increase the stability of the support frame 41, thereby ensuring the stability and reliability of the movement of the movable member 42.
In other embodiments, as shown in FIGS. 5-7, the uncapping apparatus 40 further comprises a support beam 46, the support beam 46 being connected at a first end to the movable member 42, and the clamping device 43 being mounted at a second end of the support beam 46. By providing the support beams 46, the size of the support frame 41 can be reduced, and the floor area of the support frame 41 can be reduced. As shown in fig. 6, the support beam 46 is provided so that the length of the support frame 41 can be smaller than the total length of the first station 11 and the second station 12, and the length of the support frame 41 can be increased by the support beam 46 so that the movable member 42 can reach the first station 11 or the second station 12.
In some embodiments, as shown in fig. 3, the clamping device 43 includes at least two clamping members for clamping two opposite side edges of the cover 60, respectively. By clamping the two opposite sides of the box 50, the purpose of stably clamping the box cover 60 can be achieved in a short time by using fewer clamping pieces, and the clamping efficiency is effectively improved.
In some embodiments, as shown in fig. 6, the clamping device 43 includes four clamping members, and two opposite sides of the cover 60 are clamped by two clamping members, respectively. The clamping area can be increased by the arrangement, and the clamping stability is improved.
In some embodiments, the clamping device 43 includes at least four clamping members for clamping four sides of the cover 60, respectively. This arrangement allows the cover 60 to be gripped from four sides, reducing the likelihood of the cover 60 tipping over.
In some embodiments, the uncapping apparatus 40 further comprises a cross-shaped mounting base connected to the movable member 42, and at least four clamping members are respectively mounted at four ends of the cross-shaped mounting base. Through the arrangement of the cross-shaped mounting seat, at least four clamping pieces can be kept in the same plane, and the balance of the at least four clamping pieces is kept.
In some embodiments, the drive device 44 includes a drive member for driving the conveyor chain in motion and a conveyor chain to which the movable member 42 is connected. The driving member drives the conveying chain to perform a closed loop motion, and drives the movable member 42 to perform a reciprocating motion between the first station 11 and the second station 12.
In some embodiments, the tobacco shred packaging system further comprises two material pressing devices for compacting the tobacco shreds in the box 50, which are respectively arranged above the first station 11 of the first production line 10 and above the first station 11 of the second production line 20. The material pressing device can compact the tobacco shreds in the box body 50 to prevent the tobacco shreds from scattering.
The pressing device comprises a pressing body and a pressing head, and the pressing head can be lifted up and down relative to the pressing body. When the tobacco shreds are required to be compacted, the pressure head descends, and continues to descend after contacting the tobacco shreds until the compaction requirement is met, and the pressure head can be kept at the lowest position for a preset time to improve the compaction effect. After a preset time, the pressure head rises to complete the compaction operation. After the compacting operation is completed, when the pressing head rises to the preset position, the box body 50 can be conveyed to the second station 12 so as to empty the first station 11, and the next empty box body 50 can enter the first station 11 in time to perform the next boxing operation.
The tobacco packing system further includes a conveyor 70, and the conveyor 70 is used for conveying the box 50. The conveyor 70 may transfer the box 50 from the first station to the second station. A conveyor 70 may be provided for each line.
The working principle of an embodiment of the tobacco shred packaging system of the invention is explained as follows:
as shown in fig. 1, the cut tobacco packing system includes a first production line 10 (indicated by line 1) and a second production line 20 (indicated by line 2), which alternately perform the cut tobacco packing operation.
For example, in the related art, the flow of the tobacco shred boxing system is as follows: in the process of filling the cut tobacco with the No. 1 line, the No. 2 line completes cut tobacco compaction → pressure head recovery → material head recovery → solid box capping → full box moving out → next empty box in place → cap taking → hopper 31 moving downwards → filling, and the steps are repeated in this way to complete batch cut tobacco filling. In the process, cap taking and capping are carried out at the same station, and before the next empty box enters, the next empty box can enter only after the processes of cap removing, wire loading, compacting and capping of the last box body 50 are completed.
Specifically, in the related art, the time consumed by each link in the tobacco shred boxing process is as follows:
1. the moving-out of the previous solid box needs 6s, the moving-in-place of the next empty box needs 6s, and the total time is 12 s;
2. taking down the box cover 60 on the empty box for 8 s;
3. it takes 3s for the hopper 31 to move down to the position;
4. tobacco shreds are boxed, calculated according to the boxing flow of 11000kg/h, 180kg of tobacco shreds can be loaded in each box body 50, and the total time consumed when an empty box is filled is 58.9 s;
5. the time for compacting the tobacco shreds is 15s, the pressure maintaining time is 10s, and the total time is 25 s;
6. the total recovery time of the pressure head is 15 s; meanwhile, the recovery time of the hopper 31 is 3 s; the capping and uncapping device 40 returns to the original station with the cap and caps, and takes 8 seconds.
The three operations of recovering the ram, recovering the hopper 31 and capping can be performed simultaneously, that is, the hopper 31 can be lifted simultaneously in the process of lifting the ram, the ram is lifted for 9s, the capping can be started by the capping and decapping device 40 when the ram is lifted away from the box top, and the time is 8s (including the process that the capping and decapping device 40 returns to the boxing station 1s, the capping is performed for 6s, and the capping returns to the initial position 1s), so that the total time of the three operations of recovering the ram, recovering the hopper 31 and capping is 9s +8s which is 17 s.
Thus, the time consumed to assist in binning each flow can be calculated as:
firstly, moving out the full box, and taking 12s when the empty box is in place;
② the time consumed for taking the cover is 8s (including the step of adding the cover removing device 40 to enter the boxing station for 1s, the step of taking the cover for 6s,
covering back to the initial station 1 s);
thirdly, the hopper 31 moves downwards to the position for 3 s;
fourthly, the compacting time is 25s (including 15s of pressing head and 10s of pressure maintaining time);
fifthly, recovering the pressure head, recovering the hopper 31 and covering the original station for 17 s.
Therefore, the total time for auxiliary boxing is as follows: 12s +8s +3s +25s +17s ═ 65s
According to the specification of the tobacco shred boxes, 180kg of tobacco shreds are packed in each box, 61.1 boxes can be packed per hour according to the flow requirement of 11000kg/h (11000kg/h divided by 180 kg/box is 61.1 boxes/h), and the time consumed for packing each box is 58.9s (3600 seconds divided by 61.1 boxes is 58.9 seconds/box). If the total time of the auxiliary packing is 65s, the machine is stopped for waiting about 6s (the auxiliary packing time is 65s minus the tobacco shred filling time is 58.9s) before the next packing can be carried out.
In order to ensure the continuity of the boxing, the boxing time and the auxiliary boxing time should be equal, so that the feeding device 30 is prevented from stopping and waiting. If the tobacco shred filling time and the auxiliary boxing time are 65s and the boxing speed is reduced to 3600/65 x 180 kg/box-9969 kg/h according to the specification of 180 kg/box, the boxing speed is reduced to ensure the continuity of boxing.
The reduction of the packing speed will inevitably affect the reduction of the production efficiency. The inventor finds that in order to ensure that the boxing speed can meet the requirement and ensure the boxing continuity, the boxing mode can be improved, and the auxiliary boxing time is reduced, so that the auxiliary boxing time is not more than 58.9s of the tobacco shred filling time.
To achieve the above object, the inventors propose an improved tobacco shred packaging system. The improved core of the system is as follows: after the empty box is filled with the cut tobacco, the compaction device leaves the box top, the capping and uncapping device 40 does not need to take the box cover 60 to return to the original boxing station for capping, but the empty box is filled with the cut tobacco and then leaves the original boxing station for capping to another station, so that the capping time of 8s can be reduced.
The specific process of the embodiment of the application is as follows:
after the empty box is filled with the cut tobacco at the first station 11, the empty box is moved out of the first station 11 to the second station 12, and the capping is finished at the second station 12; meanwhile, after the cigarette box moves out of the first station 11, the next empty box can enter the first station 11. That is, the empty box can be removed from the first station 11 after it is filled, without waiting for capping to be completed, and therefore the auxiliary packing time is equivalent to 8 seconds required for capping operation.
In the embodiment of the present invention, the time consumed for each process of auxiliary boxing is as follows:
firstly, moving out the full box, and taking 12s when the empty box is in place;
② the time consumed for taking the cover is 8s (including the step of adding the cover removing device 40 to enter the boxing station for 1s, the step of taking the cover for 6s,
covering back to the initial station 1 s);
thirdly, the hopper 31 moves downwards to the position for 3 s;
fourthly, the compacting time is 25s (including 15s of pressing head and 10s of pressure maintaining time);
and fifthly, recovering the pressure head for 9s, enabling the hopper 31 to simultaneously ascend in the ascending process of the pressure head, enabling the solid box to leave the first station 11 when the pressure head ascends for 9s and leaves the box top, and continuously ascending the pressure head. After the solid box leaves the first station 11, the next empty box enters, i.e. the flow of the first step.
It can be seen that the total time for auxiliary packing is 12s +8s +3s +25s +9 s-57 s
In summary, the auxiliary packing time is 57s according to the requirement of filling 180kg of cut tobacco in each box, and if the full time of each box can also be increased to 57 s/box, the single-box packing period is 57s +57 s-114 s, so that the packing capacity can be increased to 3600/57, 180 kg-11368 kg/h. In the related art, if the auxiliary boxing time is 65s and the boxing capacity is 9969kg/h, the boxing system provided by the embodiment of the invention can effectively improve the feeding flow and improve the boxing efficiency.
The invention also provides a tobacco shred boxing method, which comprises the following steps:
providing a first production line 10 and a second production line 20 which are arranged in parallel, wherein a first station 11 and a second station 12 positioned at the downstream of the first station 11 are arranged on both the first production line 10 and the second production line 20;
conveying the empty boxes 50 to the first station 11 of the first line 10 and to the first station 11 of the second line 20;
the two cover adding and removing devices 40 are used for respectively removing the box covers 60 on the box bodies 50 on the first production line 10 and the second production line 20;
firstly, the feeding device 30 is used for filling tobacco shreds into the box body 50 on the first production line 10, and then the feeding device 30 moves to fill the tobacco shreds into the box body 50 on the second production line 20;
the box 50 of the first line 10 is transferred from the first station 11 to the second station 12 before the box 50 of the second line 20 is filled, and the box cover 60 is replaced on the box 50 by the uncapping device 40 after the box 50 reaches the second station 12.
In some embodiments, the tobacco shred boxing method further comprises:
when the feeding device 30 moves to load the cut tobacco into the box 50 on the second production line 20, the cut tobacco of the box 50 on the first production line 10 is compacted by the pressing device.
In some embodiments, the tobacco shred boxing method further comprises:
after compaction is complete, the binder is raised and the carton 50 on the first line 10 is transported from the first station 11 to the second station 12 as the binder is raised to a position clear of the top of the carton 50.
