[0002] In the tobacco logistics industry, when cigarettes are to be shipped out of the warehouse, the cigarettes stacked on the pallet at a high position need to be transported to the sorting workshop at a low position through a conveying device, so as to facilitate the workers in the sorting workshop to sort the cigarettes. The conveying device used in a certain workshop includes a first roller conveyor, an inclined flat belt conveyor and a second roller conveyor arranged in sequence from left to right, wherein the installation height of the roller of the first roller conveyor is greater than the installation height of the roller of the second roller conveyor, the inclined flat belt conveyor is inclined to the right, the left end of the inclined flat belt conveyor is docked with the end port of the first roller conveyor, and the right end of the inclined flat belt conveyor is docked with the head port of the second roller conveyor.

[0003] The method of using the conveying device to convey all cigarettes at a high position on the tray to the sorting workshop at a low position is:

[0004] Workers turn on the first roller conveyor, the inclined flat belt conveyor and the second roller conveyor; workers place the cigarette pieces on the pallet one by one on the roller of the first roller conveyor, the roller conveys the cigarette pieces to the right, and then the cigarette pieces are conveyed to the flat belt of the inclined flat belt conveyor, the inclined flat belt conveyor conveys the cigarette pieces to the roller of the second roller conveyor, and the roller of the second roller conveyor conveys the cigarette pieces to the sorting workshop at a low position, thereby finally realizing the conveyance of all the cigarette pieces on the pallet at a high position to the sorting workshop at a low position.

[0005] However, although this conveying device can be used, it still has the following technical defects:

[0006] I. The total length of the first roller conveyor, the inclined flat belt conveyor and the second roller conveyor is relatively long, which undoubtedly occupies a large amount of space in the workshop.

[0007] II. When the output height of the cigarette pieces needs to be lowered, it is necessary not only to adjust the height of the second roller conveyor, but also to adjust the height or angle of the inclined flat belt conveyor, and the total adjustment time is long, so that the cigarette pieces cannot be quickly transported out from different heights. Therefore, a conveyor that occupies a small workshop space and can quickly transport the cigarette pieces from different heights is urgently needed. Utility Model Content

[0036] like Figure 1 to Figure 7 As shown, an automatic reversing conveying device for cigarette pieces comprises a first roller conveyor 1 and a circulating chain elevator 2 which are arranged in sequence from left to right, a second roller conveyor 3 which is arranged longitudinally is arranged on the front side of the circulating chain elevator 2, the installation height of the roller 4 of the second roller conveyor 3 is smaller than the installation height of the roller 4 of the first roller conveyor 1, a plurality of longitudinal belt conveyors 6 which are arranged longitudinally are fixedly arranged on the rear side of the frame 5 of the second roller conveyor 3, and the belts 7 of each longitudinal belt conveyor 6 are all on the same plane; a connecting plate 8 is fixedly provided on the right end portion of the frame 5 of the first roller conveyor 1, and a plurality of rollers 9 are rotatably installed on the rear end surface of the connecting plate 8.

[0037] The circulating chain hoist 2 comprises a frame 10, a vertical plate 11 fixed in the frame 10 and arranged vertically, an upper sprocket 13 and a lower sprocket 14 are rotatably mounted on the front end surface of the vertical plate 11 and at the upper and lower ends thereof via a rotating shaft 12, a chain 15 is mounted between the upper sprocket 13 and the lower sprocket 14, a driving motor 16 is fixed on the top of the frame 10, and a transmission mechanism is connected between the driving motor 16 and the rotating shaft 12 at the upper end;

[0038] An annular guide rail 17 located outside the upper sprocket 13 and the lower sprocket 14 is also fixedly provided on the front end surface of the vertical plate 11, and bracket seats 18 are fixedly provided on the chain 15 at intervals along its length direction. Each bracket seat 18 is slidably installed on the annular guide rail 17, and a bracket 20 is rotatably installed on the front end surface of each bracket seat 18 via a pin 19. A plurality of spaced support rods 21 are fixedly provided on the front end surface of each bracket 20, and four support rods 21 are fixedly provided on the front end surface of the bracket 20, and the spacing between each two adjacent brackets 20 on the chain 15 is equal.

[0039] The transmission mechanism includes a driving sprocket 22 fixed on the output shaft of the driving motor 16, a driven sprocket 23 fixed on the upper rotating shaft 12, and an endless chain is installed between the driving sprocket 22 and the driven sprocket 23. The rear end of the bracket of the longitudinal belt conveyor 6 is fixed on the rear end of the frame 5 of the second roller conveyor 3.

[0040] The conveying device also includes a controller, which is electrically connected to the drive motor 16, the first roller conveyor 1, the second roller conveyor 3 and the longitudinal belt conveyor 6 via a signal line. Workers can control the start or shut down of the drive motor 16, the first roller conveyor 1, the second roller conveyor 3 and the longitudinal belt conveyor 6 through the controller, which facilitates the workers' operation.

[0041] The working process of the utility model is as follows:

[0042] S1, control the first roller conveyor 1, the second roller conveyor 3 and the longitudinal belt conveyor 6 to start, the rollers 4 on the first roller conveyor 1 and the second roller conveyor 3 are rotated, and the belt 7 on the longitudinal belt conveyor 6 is rotated; at the same time, control the drive motor 16 to start, the drive motor 16 drives the active sprocket 22 to rotate clockwise, the active sprocket 22 drives the upper rotating shaft 12 to rotate synchronously, the rotating shaft 12 drives the upper sprocket 13 to rotate clockwise, the upper sprocket 13 drives the lower sprocket 14 to rotate synchronously through the chain 15, at the same time, each bracket seat 18 on the chain 15 moves along the length direction of the annular guide rail 17, the bracket seat 18 drives the bracket 20 to move synchronously, and the bracket 20 drives the support rod 21 thereon to move synchronously;

[0043] S2, the worker places the first cigarette piece 24 on the pallet on the roller 4 of the first roller conveyor 1, and the roller 4 conveys the cigarette piece 24 to the right;

[0044] S3, when the first cigarette 24 is conveyed to the roller 9 by the roller 4 of the first roller conveyor 1, the support rods 21 on the bracket 20 cross each roller 9 upward, as shown in FIG. Figure 8-Figure 9 As shown, the cigarette pieces 24 on the roller table 9 are lifted up, and the lifted cigarette pieces 24 are translated along the length direction of the annular guide rail 17;

[0045] When each support rod 21 on the bracket 20 crosses downward through each longitudinal belt conveyor 6, as shown in FIG. Figure 10 to Figure 12 As shown, the cigarette pieces 24 are supported on the belts 7 of each longitudinal belt conveyor 6. At this time, the belts 7 convey the cigarette pieces 24 to the rollers 4 of the second roller conveyor 3, and the rollers 4 of the second roller conveyor 3 convey the cigarette pieces 24 to the sorting workshop at a low position, as shown in FIG. Fig.13 As shown, the first cigarette 24 is finally transported to the low-level sorting workshop;

[0046] S4. The worker repeats the operations of steps S2 to S3, and finally transports all the cigarette pieces 24 at a high position on the tray to the sorting workshop at a low position.

[0047] Since the first roller conveyor 1 and the endless chain elevator 2 are arranged horizontally, and the second roller conveyor 3 is arranged longitudinally, the horizontal length of the reversing conveying device is smaller than the horizontal length of the traditional conveying device, and therefore, it does not occupy space in the workshop.

[0048] In addition, when the output height of the cigarette pieces 24 needs to be lowered, it is only necessary to adjust the height of the second roller conveyor 3, so that the cigarette pieces 24 can be transported out from different heights in a short time. It can be seen that compared with the traditional conveying device, the reversing conveying device does not need to adjust the height or angle of the inclined flat belt conveyor, nor does it need to adjust the height of the second roller conveyor 3, thereby greatly shortening the height adjustment time and being able to quickly transport the cigarette pieces 24 from different heights.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
