[0002] According to the production needs of a cigarette industrial enterprise and the structure of a factory building, the finished piece tobacco needs to be lifted during the conveying process from a cigarette connecting and packing workshop to a storage area of a finished product warehouse. The existing technology generally adopts a vertical lifting scheme such as the vertical continuous elevator of the chain type in the invention patent (201210241993.2) or a spiral lifting scheme. However, through practical application, the vertical lifting scheme has a high system failure rate due to a lifting height of about 7 meters, a long chain group, and high load. In order to avoid the tilting of a tobacco box during the spiral lifting process, a flow guiding (limiting) system is arranged to prevent the tobacco from being stuck, the channel from being blocked, and the tobacco from falling. After the flow guiding system is added, the posture of the tobacco box is guaranteed, but on the other hand, the size of the tobacco box that can be lifted is limited. For example, if the size of the cigarette or the size of the tobacco box changes, the flow guiding device of the spiral lifting system needs to be modified.

[0003] Therefore, how to provide a system and method for effectively lifting the tobacco box step by step has become a technical problem to be solved in the field. SUMMARY

[0038] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0039] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the scope of the application its application or uses.

[0040] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as if the techniques, methods, and apparatus were discussed in detail herein, where appropriate.

[0041] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0042] Note that like reference numerals and letters indicate similar items in the following drawings, and thus once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0043] According to Figures 1 to 5 As shown, a step-lifted finished piece cigarette vertical lifting system disclosed by the present application includes an input roller conveyor 10, a frame 20, an output roller conveyor 31, and a power unit 40;

[0044] The input roller conveyor 10 is connected to the bottom layer of the frame 20 through a receiving roller conveyor 11, and the output roller conveyor 31 is connected to the top layer of the frame 20 through a receiving roller conveyor 30.

[0045] The plurality of transition layers are provided between the bottom layer and the top layer of the rack 20, each of the transition layers is provided with a fixed plate 23 and a sliding plate 24, and the power unit 40 is used to drive all the sliding plates 24 to synchronously ascend or descend;

[0046] The left and right sides of the fixed plate 23 and the sliding plate 24, the side of the rack 20 close to the receiving roller conveyor 11 and the side of the rack 20 away from the receiving roller conveyor 30 are provided with reciprocating power cylinders 21, and the reciprocating power cylinders 21 are connected with push plates 22 at the extension end, so as to gradually lift the to-be-lifted cigarettes on the receiving roller conveyor 11 to the receiving roller conveyor 30.

[0047] In the implementation, in order to improve the convenience and the working quality, the reciprocating power cylinders 21 on the side of the fixed plate 23 and the side of the sliding plate 24 are alternately extended and retracted, that is, when the reciprocating power cylinders 21 on the side of the fixed plate 23 are synchronously pushed out, the reciprocating power cylinders 21 on the side of the sliding plate 24 are stopped; when the reciprocating power cylinders 21 on the side of the sliding plate 24 are synchronously pushed out, the reciprocating power cylinders 21 on the side of the fixed plate 23 are stopped, and the stroke and the linear speed of all the reciprocating power cylinders 21 are kept consistent, and the size of each push plate 22 is also kept consistent.

[0048] Further, the number of the sliding plates 24 is at least one more than the number of the fixed plates 23, so that Figure 2 Taking the angle of view, all the fixed plates 23 are on the left side of the system, and all the sliding plates 24 are on the right side of the system, in combination with the total height speed of lifting and the actual structure of the factory building, when the number of the sliding plates 24 needed is N layers, the number of the fixed plates 23 used is N-2, and the positions of the reduced fixed plates 23 are arranged for the receiving roller conveyor 11 and the receiving roller conveyor 30. The sizes of the object-carrying surfaces of all the sliding plates 24 and the fixed plates 23 and the vertical spacing of each layer of the plates are completely equal, and are greater than the maximum size of the expected to-be-lifted cigarettes to pass through the system. The extra sliding plates 24 are flush with the receiving roller conveyor 11 and / or the receiving roller conveyor 30, so as to ensure that the to-be-lifted cigarettes can be transferred from the receiving roller conveyor 11 to the bottommost sliding plate 24 or from the topmost sliding plate 24 to the receiving roller conveyor 30 under the pushing action of the reciprocating power cylinders 21.

[0049] Further, in each transition layer, the fixed plate 23 is flush with the sliding plate 24. In this way, when the reciprocating power cylinders 21 push the to-be-lifted cigarettes, the to-be-lifted cigarettes can be effectively transferred from the fixed plate 23 to the sliding plate 24 or from the sliding plate 24 to the fixed plate 23.

[0050] Further, the front and back sides of the fixed plate 23 are provided with at least two fixed supports 27, and the fixed supports 27 are fixedly connected with the rack 20. The positions of the fixed plate 23 and the rack 20 are fixed through the plurality of fixed supports 27, so as to ensure the stability.

[0051] Further, the front and back sides of the movable plate 24 are provided with at least two sliding blocks 28, and the rack 20 is provided with sliding rails 25 corresponding to the sliding blocks 28, the sliding blocks 28 are raised or lowered along the sliding rails 25 to drive the movable plate 24 to be raised or lowered. Compared with the traditional vertical lifting and spiral lifting system of the piece cigarette box, the movable plate 24 of the present application only needs to be raised and lowered by one layer, and reciprocates, and does not need to be raised by a high height as a whole, and is relatively safer.

[0052] Further, the front and back sides of all the movable plates 24 are connected through connecting rods 26, so that the movable plates 24 can be synchronously raised or lowered as a whole. Under the action of the power unit 40, it is ensured that all the movable plates 24 can synchronously reciprocate up and down along the sliding rails 25.

[0053] In the setting, the power unit 40 used in the present application includes but is not limited to a pneumatic cylinder, a hydraulic cylinder or an electric push rod structure, and the bottommost movable plate 24 can be connected with the telescopic end of the aforementioned power unit 40, so as to ensure that the aforementioned power unit 40 can effectively drive the movable plate 24 to be raised or lowered.

[0054] Further, the receiving roller conveyor 11 is arranged directly below the bottommost fixed plate 23, and the receiving roller conveyor 30 is arranged directly below the topmost fixed plate 23. As mentioned above, the stroke and linear speed of all the reciprocating power cylinders 21 are consistent. Therefore, the width of the receiving roller conveyor 11 and the receiving roller conveyor 30 is basically consistent with that of the fixed plate 23.

[0055] In accordance with Figure 6 As shown in FIG. 1, it is a flowchart of the vertical lifting method of the piece cigarette disclosed by the present application, using the vertical lifting system of the piece cigarette of the present application, and the following steps are as follows:

[0056] S1, the piece cigarette to be lifted enters the receiving roller conveyor 11 in sequence through the input roller conveyor 10; the receiving roller conveyor 11 is provided with no flow guide device on both sides, and the upper surface of the roller conveyor is higher than the rack 20 of the roller conveyor;

[0057] S2, the power unit 40 pulls the movable plate 24 to move downward until the loading surface of the bottommost movable plate 24 is flush with the receiving roller conveyor 11;

[0058] S3, the bottommost reciprocating power cylinder 21 is pushed out to push the piece cigarette to be lifted on the receiving roller conveyor 11 onto the bottommost movable plate 24; after being pushed to the position, the bottommost reciprocating power cylinder 21 is retracted to return to the initial position, and the receiving roller conveyor 11 receives the second piece cigarette to be lifted.

[0059] S4, the bottommost reciprocating power cylinder 21 is reset, the power unit 40 pulls the movable plate 24 to be raised until the loading surface of the bottommost movable plate 24 is flush with the loading surface of the bottommost fixed plate 23;

[0060] S5, the reciprocating power cylinder 21 on the side of the one layer of moving plates 24 is extended to push the second piece of tobacco to be lifted onto the one layer of moving plates 24; then, the reciprocating power cylinder 21 on the side of the one layer of moving plates 24 is retracted, and after the retraction is completed, the power unit 40 pulls the moving plates 24 to move downward until the surface of the one layer of moving plates 24 is flush with the upper surface of the roller bed of the receiving roller bed machine 11, so as to push the second piece of tobacco to be lifted onto the one layer of moving plates 24.

[0061] S6, the steps of S2 to S5 are repeated until the tobacco to be lifted is pushed to the receiving roller bed machine 30 and transported to the next process through the output roller bed machine 31.

[0062] Further, in S6, when the reciprocating power cylinder 21 on the bottom layer is extended, the reciprocating power cylinder 21 on the side of the one layer of fixed plates 23 is synchronously extended to push the last piece of tobacco to be lifted to the second transition layer, and the tobacco to be lifted is lifted step by step in a Z-shaped trajectory.

[0063] In the implementation, taking the present application as an example, the intermediate transition layer is provided with three layers, after step S5, the first piece of tobacco to be lifted is located on the one layer of fixed plates 23; at this time, returning to step S2, the second piece of tobacco to be lifted is pushed onto the one layer of moving plates 24 under the action of the reciprocating power cylinder 21 on the bottom layer, and the first piece of tobacco to be lifted is pushed onto the one layer of moving plates 24 under the synchronous action of the reciprocating power cylinder 21 on the side of the one layer of fixed plates 23, at this time, the one layer of moving plates 24 and the one layer of fixed plates 24 respectively carry the second piece of tobacco to be lifted and the first piece of tobacco to be lifted. Then the moving plates 24 are synchronously lifted by the power unit 40, then the first piece of tobacco to be lifted is lifted to the second transition layer, and the second piece of tobacco to be lifted is lifted to the first transition layer. In this way, when the third piece of tobacco to be lifted is pushed to the first transition layer, the first piece of tobacco to be lifted is lifted to the third transition layer, and the second piece of tobacco to be lifted is lifted to the second transition layer, so that the tobacco to be lifted is lifted step by step in a Z-shaped trajectory.
