Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco production machinery, and more specifically, to a tobacco box conveying buffer device. Background Technology
[0002] Current automated cigarette box loading equipment generally adopts a single-channel cigarette box conveying method followed by unloading and stacking. This method has the following disadvantages: when the unloading and stacking mechanism is lifting and stacking, all the cigarette boxes completed at the station are placed on the production line. At this time, due to the limited length, blockage will inevitably occur at the outlet and inlet, affecting the flow of cigarette boxes and production efficiency.
[0003] Utility model patent CN216853785U discloses a cigarette box conveying device and a cigarette box logistics system. The cigarette box conveying device includes: a buffer platform with a buffer position, capable of moving along a first preset direction to convey fully loaded cigarette boxes; an empty box platform, spaced above the buffer platform along the direction of gravity, including a storage position, and capable of moving along a second preset direction; and a lifting device connected between the buffer platform and the empty box platform for transferring empty cigarette boxes from the empty box platform to the buffer platform. This cigarette box conveying device and logistics system independently convey fully loaded cigarette boxes and empty cigarette boxes after being turned over, reducing horizontal space occupation and improving space utilization. Furthermore, the connection between the buffer platform and the empty box platform via the lifting device enables rapid transfer of cigarette boxes between the two platforms, thereby improving the efficiency of the cigarette box conveying process. However, the publicly disclosed structure of the cigarette box conveying device and cigarette box logistics system does not have the function of adjusting the position of the cigarette boxes or outputting cigarette boxes in rows. Utility Model Content
[0004] In order to continuously convey and buffer tobacco boxes, eliminate waiting time for tobacco box conveying, adjust the position of tobacco boxes, and output tobacco boxes in a row, the technical solution adopted by this utility model is: a tobacco box conveying and buffering device, including a frame, a front roller assembly, a rear roller assembly, a front blocking assembly, a rear blocking assembly, a rear push plate assembly, and a front push plate mechanism.
[0005] The front roller assembly and the rear roller assembly are arranged sequentially on the frame for conveying the smoke box from back to front;
[0006] The front blocking assembly is disposed at the outer end of the front roller assembly and is used to intercept the smoke boxes conveyed by the front roller assembly so that the front push plate mechanism can sort the smoke boxes located in the front row.
[0007] The rear blocking assembly is disposed between the front roller assembly and the rear roller assembly to block the cigarette boxes conveyed by the rear roller assembly, so as to allow the front push plate mechanism to sort the cigarette boxes located in the rear row and to allow the rear push plate assembly to sort the cigarette boxes located in the rear row.
[0008] Based on the above, the front roller assembly includes a front electric roller and a plurality of front rollers, the front electric roller and the plurality of front rollers being arranged on the frame;
[0009] The rear roller assembly includes a rear electric roller and a plurality of rear rollers, which are arranged on the frame.
[0010] The front electric roller is connected to several front rollers, and the rear electric roller is connected to several rear rollers via multi-wedge belt drives.
[0011] Beneficial effects: By dividing the rollers on the frame into two parts and driving them separately by the rear electric roller and the front electric roller, the segmented conveying of the tobacco boxes can be achieved, which makes it easier to buffer the tobacco boxes into two rows.
[0012] Based on the above, the front push plate mechanism includes a front rack, a pair of front slide rails, and a pair of front push plate moving assemblies. The front push plate moving assemblies are slidably disposed on the front slide rails and mesh with the front rack for transmission.
[0013] Based on the above, the front push plate moving assembly includes a front bracket, a front push plate, a front reduction motor, and a front gear mounted on the front reduction motor. The front push plate is vertically mounted on the front bracket, and the front reduction motor is mounted on one side of the front bracket to drive the front gear to mesh with the front rack, thereby driving the front bracket to slide along the front slide rail.
[0014] Beneficial effects: By designing the front push plate mechanism as a pair of relatively moving front push plate moving components, the relative movement between the front push plate moving components can be used to move and clamp the tobacco boxes, thereby eliminating gaps between tobacco boxes and improving the neatness of the buffer.
[0015] Based on the above, a pair of front sliders that slide in cooperation with the front slide rail are provided at the bottom of the front bracket.
[0016] Based on the above, the rear push plate assembly includes a rear rack, a rear bracket, a rear push plate, a pair of rear slide rails, a rear reduction motor, and a rear gear mounted on the rear reduction motor;
[0017] The rear push plate is vertically mounted on the rear support, and the rear reduction motor is mounted on one side of the rear support. It is used to drive the rear gear to mesh with the rear rack, thereby driving the rear support to slide along the rear slide rail.
[0018] Beneficial effects: By setting a rear push plate assembly at the rear of the frame, on the one hand, when buffering the front rows of cigarette boxes, the front rows of cigarette boxes can be staggered, making it easier for the front push plate moving assembly to arrange the cigarette boxes; on the other hand, it also facilitates the left and right movement of the rear rows of cigarette boxes.
[0019] Based on the above, the front blocking assembly and the rear blocking assembly have the same structure. The front blocking assembly includes a blocking bracket, a lead screw stepper motor, and a connecting bracket. The lead screw stepper motor is connected to the blocking bracket through the connecting bracket, and the lead screw stepper motor is used to push the blocking bracket to move up and down.
[0020] Based on the above, the front blocking assembly further includes a mounting base for mounting the lead screw stepper motor. The mounting base is vertically provided with a limit bracket, the limit bracket is provided with a limit hole, and the connecting bracket is provided with a limit plate inserted into the limit hole. The limit hole is used to control the lifting range of the connecting bracket.
[0021] Beneficial effects: Using limit holes to control the lifting range of the connecting bracket prevents the connecting bracket from dislodging from the lead screw stepper motor, thus increasing safety.
[0022] Based on the above, vertical slide rails are provided on both sides of the blocking bracket, and vertical sliders are provided on the frame corresponding to the vertical slide rails, with the vertical slide rails and vertical sliders slidingly engaged.
[0023] Based on the above, the front blocking assembly and the rear blocking assembly are arranged in parallel; the rear push plate assembly and the front push plate mechanism are arranged in parallel.
[0024] This utility model has substantial features and progress compared to the prior art. Specifically, the present utility model provides a cigarette box conveying buffer device, which, by analyzing the conveying path of the cigarette box, is designed to have push plate components and blocking components that can be staggered into two rows. Thus, when buffering the cigarette box, the buffer position can be flexibly adjusted according to the actual position of the cigarette box, effectively avoiding material blockage. It also has the functions of material position adjustment and whole row output.
[0025] Furthermore, by setting a rear push plate, a left push plate, and a right push plate, the position of the subsequent tobacco boxes can be adjusted using the rear push plate, ensuring that the tobacco boxes in the first row are staggered when arranged to form a row, thereby improving the smoothness and continuity of the tobacco box buffering process.
[0026] Furthermore, by setting the left and right push plates opposite each other, the relative movement of the left and right push plates can be used to clamp the first row of smoke boxes, thereby eliminating gaps between the smoke boxes and improving the neatness of the buffer.
[0027] Furthermore, by providing a limiting plate that inserts into the limiting hole on the connecting bracket, the lifting range of the connecting bracket can be controlled using the limiting hole, preventing the connecting bracket from dislodging from the lead screw stepper motor.
[0028] Therefore, this cigarette box conveying and buffering device can continuously convey and buffer cigarette boxes, eliminating waiting time during cigarette box conveying and effectively improving production efficiency. Attached Figure Description

[0035] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0036] Example 1
[0037] This embodiment provides a cigarette box conveying buffer device, such as...

The front roller assembly and the rear roller assembly are arranged sequentially on the frame 1 for conveying the smoke box 12 from back to front.
[0038] The front blocking assembly is disposed at the outer end of the front roller assembly and is used to intercept the tobacco boxes conveyed by the front roller assembly, so that the front push plate mechanism can sort the tobacco boxes 12 located in the front row. The rear blocking assembly is disposed between the front roller assembly and the rear roller assembly and is used to block the tobacco boxes 12 conveyed by the rear roller assembly, so as to allow the front push plate mechanism to sort the tobacco boxes located in the rear row and allow the rear push plate assembly to sort the tobacco boxes located in the rear row.
[0039] Specifically, such as Figure 1 As shown, the front roller assembly includes a front electric roller 9 and a plurality of front rollers 10.

[0041] The front push plate moving assembly includes a front support 13, a front push plate, a front reduction motor 17, and a front gear 14 mounted on the front reduction motor 17. The front push plate is vertically mounted on the front support 13, and the front reduction motor 17 is located on one side of the front support 13, used to drive the front gear 14 to mesh with the front rack 15, thereby causing the front support 13 to slide along the front slide rail 16. Specifically, according to their distribution positions, the front push plate can be divided into a left push plate 4 and a right push plate 8.
[0042] Specifically, such as Figure 4 As shown, the rear push plate assembly includes a rear rack 21, a rear bracket 22, a rear push plate 5, a pair of rear slide rails 20, a rear reduction motor 24, and a rear gear 19 mounted on the rear reduction motor 24. The rear push plate 5 is vertically mounted on the rear bracket 22, and the rear reduction motor 24 is located on one side of the rear bracket 22, used to drive the rear gear 19 to mesh with the rear rack 21, thereby driving the rear bracket 22 to slide along the rear slide rails 20. A rear slider 23 is provided at the bottom of the rear bracket 22.
[0043] like Figure 5 As shown, the front blocking assembly has the same structure as the rear blocking assembly. The front blocking assembly includes a blocking bracket 31, a lead screw stepper motor 25, and a connecting bracket 28. The lead screw stepper motor 25 is connected to the blocking bracket 31 through the connecting bracket 28, and the lead screw stepper motor 25 is used to push the blocking bracket 31 to move up and down.
[0044] Example 2
[0045] This embodiment provides a cigarette box conveying buffer device. The main difference from Embodiment 1 is that, in this embodiment, the front blocking assembly further includes a mounting base for mounting the lead screw stepper motor 25. A limit bracket 27 is vertically mounted on the mounting base, and the limit bracket 27 has a limit hole. A limit plate 26 is provided on the connecting bracket 28 and inserted into the limit hole. The limit hole is used to control the lifting range of the connecting bracket 28.
[0046] Example 3
[0047] This embodiment provides a cigarette box conveying buffer device. The main difference from Embodiment 1 is that, in this embodiment: vertical slide rails 30 are provided on both side walls of the blocking bracket 31, and vertical sliders 29 are provided on the frame 1 corresponding to the vertical slide rails 30. The vertical slide rails 30 and the vertical sliders 29 are slidably engaged. A pair of front sliders 18 are provided at the bottom of the front bracket 13, which are slidably engaged with the front slide rails 16.
[0048] Example 4
[0049] This embodiment provides a cigarette box conveying buffer device. The main difference from Embodiment 1 is that in this embodiment, the front blocking component and the rear blocking component are arranged in parallel; the rear push plate component and the front push plate mechanism are arranged in parallel.
[0050] Specifically, the workflow for buffering tobacco boxes using the tobacco box conveying and buffering device provided by this utility model is as follows:
[0051] The left push plate 4 and the rear push plate 5 are moved to one end of the frame, and the right push plate 8 is moved to the other end of the frame. When the smoke box 12 is conveyed to the front end by the roller conveyor assembly, it is blocked by the raised front blocking assembly 11 at the position of the left push plate 4 and the right push plate 8. Then the left push plate 4 moves the smoke box 12 to the right, completing the buffering of the first smoke box.
[0052] Then, the rear blocking assembly 3 is raised, blocking the second smoke box near the rear push plate. The rear push plate 5 is used to push the second smoke box to the left, so that the second smoke box is offset from the first smoke box. After the left push plate 4 returns to its left position, the rotation of the front roller and the rear roller transports the second smoke box to the front blocking assembly 11, so that the first smoke box and the second smoke box are aligned together.
[0053] Subsequently, due to the reduction in translation distance, the rear blocking component 3 can be moved without raising it. The third and fourth smoke boxes are then pushed to the left in sequence by the rear push plate 5 and then transported to the vicinity of the front blocking component 11, thereby completing the first row of buffering.
[0054] After the first row of smoke boxes is completed, the rear blocking component 3 is raised, and the rear push plate 5 is positioned in the middle of the rear roller 6. The subsequent smoke boxes are blocked at the rear blocking component 3, and the rear push plate 6 is used to push the smoke boxes to the left and right sides in sequence until they are full, thus completing the buffering of the second row of smoke boxes.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
