Description

Technical Field

[0001] This utility model belongs to the field of cigarette sorting and conveying technology, specifically relating to a circular cigarette belt conveyor with standard and fine collinear buffer. Background Technology

[0002] In the process of sorting cigarette packs, belt conveyors are typically used for conveying and buffering the cigarette packs; existing belt conveyors are generally divided into two types: linear and S-shaped.

[0003] Linear belt conveyors are suitable for all types of cigarette packs, including standard cigarettes, standard slim cigarettes, and irregularly shaped cigarettes. However, linear belt conveyors have the disadvantage of taking up a lot of space, making them difficult to apply in small and medium-sized factories with limited space.

[0004] S-type belt conveyors can be buffered in multiple layers and have the advantage of occupying little space. However, S-type belt conveyors are only suitable for conveying a single standard type of cigarette pack. If standard cigarettes, standard slim cigarettes, and irregularly shaped cigarettes are mixed and conveyed, cigarette packs of different sizes are very likely to get stuck or jammed when passing through the S-curve. This can also cause different types of cigarette packs to be squeezed and deformed at the S-curve.

[0005] Therefore, in order to achieve efficient sorting of standard and fine collinear mixing, it is essential to provide a circular cigarette conveyor belt with standard and fine collinear buffer in this application. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A standard collinear buffered annular cigarette conveyor includes an annular conveyor belt and at least one cigarette pressing device; the annular conveyor belt includes at least one arc-shaped section extending longitudinally along a central axis, such that the two ends of the annular conveyor belt respectively form an upper inlet and a lower outlet; the cigarette pressing device is arranged on the upstream side of the arc-shaped section along the cigarette feeding direction of the annular conveyor belt, so as to block the conveying from the upstream side to the arc-shaped section when the arc-shaped section is fully loaded.

[0008] Preferably, the annular conveyor belt further includes a smoke inlet section and a smoke outlet section respectively connected to the inlet and the outlet.

[0009] Preferably, both the smoke inlet section and the smoke outlet section are constructed as linear conveying structures.

[0010] Preferably, the smoke inlet section and the smoke outlet section extend in opposite directions along the tangent direction of the arc-shaped section.

[0011] Preferably, the annular conveyor belt includes two opposing arc-shaped segments and a smoke guide segment connecting the two arc-shaped segments. Both arc-shaped segments are constructed as semi-annular conveying structures, and the smoke guide segment is constructed as an inclined straight-line conveying structure, so that the two arc-shaped segments are staggered longitudinally.

[0012] Preferably, at least the arc-shaped segment is configured as an active conveying component, which includes a roller, a conveyor belt, and a motor, wherein the motor drives the roller to rotate so that the conveyor belt can circulate and convey.

[0013] Preferably, the smoke-pressing device includes a transition section of a linear conveying structure and a smoke-pressing plate that can be raised and lowered longitudinally relative to the transition section. When the smoke-pressing plate is raised to its highest position relative to the transition section, a conveying channel is formed between the smoke-pressing plate and the transition section, allowing the cigarette packs to pass through.

[0014] Preferably, a gantry bracket arranged along the width direction is fixed on the transition section, and a smoke-pressing cylinder for driving the smoke-pressing plate to move longitudinally is fixed on the gantry bracket.

[0015] Preferably, a hinge is connected between the telescopic end of the smoke-pressing cylinder and the smoke-pressing plate, so that the smoke-pressing plate can swing relative to the transition section, and the swing center axis of the smoke-pressing plate extends axially along the width direction of the transition section.

[0016] Preferably, the hinge component includes a first hinge frame, a second hinge frame, and a rotating shaft. The first hinge frame and the second hinge frame are rotatably connected via the rotating shaft, and the first hinge frame and the second hinge frame are fixedly connected to the smoke-pressing cylinder and the smoke-pressing plate, respectively.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] 1. Compared with straight belt conveyors, the circular cigarette conveyor of this utility model has the advantages of small footprint and long buffer distance, and can be effectively applied to cigarette sorting sites with limited space.

[0019] 2. Compared with the S-type belt, the circular cigarette conveyor of this utility model can effectively avoid problems such as cigarette blockage and jamming, and mutual compression of different types of cigarette packs. It has the advantage of efficiently realizing the mixed buffering and conveying of different types of cigarette packs, thus being effectively applicable to the mixed sorting of standard and fine cigarette packs.

[0020] 3. In this utility model, a hinged connector is used to connect the smoke-pressing cylinder and the smoke-pressing plate, so that the smoke-pressing plate can flexibly adapt to the slope changes between the linear conveying structure and the semi-circular conveying structure, thereby ensuring that the cigarette packs can be arranged flatly through the overall circular conveyor belt and avoiding problems such as smoke blockage and jamming.

[0029] For a standard and slim cigarette sorting line (mixed conveying of standard cigarettes, standard slim cigarettes, and irregularly shaped cigarettes), the system sorts cigarettes according to daily order information. The sorting schedule is that standard cigarettes are sent out first for the same customer, followed by standard slim cigarettes and irregularly shaped cigarettes. To ensure the matching between the cigarette conveying efficiency and the downstream packing efficiency, a belt conveyor is generally used for buffering the cigarette conveying. However, straight belt conveyors have the disadvantage of large footprint, and S-shaped belt conveyors are not suitable for standard and slim cigarette sorting. Therefore, this utility model provides a ring-shaped cigarette belt conveyor for standard and slim cigarette sorting with buffering.

[0030] like Figure 1 and Figure 2 As shown, the present invention provides a circular cigarette conveyor belt with collinear buffering for standard and fine cigarettes, comprising a circular conveyor belt 1 and a cigarette pressing device 2. Specifically, the cigarette pressing device 2 is used to control the arrangement of cigarettes on the circular conveyor belt 1 to ensure that the cigarettes are arranged evenly as they pass through the entire circular conveyor belt 1, thereby avoiding the problem of different types of cigarettes being squeezed and deformed.

[0031] For example, the annular conveyor belt 1 includes, as shown in the example, Figure 3 The diagram shows an upper smoke inlet section 12, a lower smoke outlet section 13, and at least one arc-shaped section 11 connecting the smoke inlet section 12 and the smoke outlet section 13. Specifically, for a sorting line where standard and slim cigarettes are collinear, when the arc-shaped section 11 is full of cigarettes, if cigarettes continue to be conveyed from the upstream side, the standard and slim cigarettes on the arc-shaped section 11 will be squeezed against each other. At this time, due to the height difference between the two, the cigarettes will be squeezed out and disordered, resulting in cigarette posture problems. Based on this, the cigarette pressing device 2 is arranged on the upstream side of the arc-shaped section 11 along the cigarette feeding direction of the annular conveyor belt 1, so as to block the conveying from the upstream side to the arc-shaped section 11 when the arc-shaped section 11 is full, thereby avoiding the mutual squeezing of different types of cigarettes on the arc-shaped section 11.

[0032] In one specific example, the arc-shaped segment 11 is constructed as a spiral ring structure (not shown in the figure) that spirals around the entire ring. The central axis of the spiral ring structure extends longitudinally, so that the upper end of the spiral ring structure forms an inlet connected to the smoke inlet segment 12, and the lower end of the spiral ring structure forms an outlet connected to the smoke inlet segment 12. It is worth noting that both the smoke inlet segment 12 and the smoke outlet segment 13 are constructed as straight conveying structures, and the smoke inlet segment 12 and the smoke outlet segment 13 extend in opposite directions along the tangent of the spiral ring structure. Therefore, when different types of cigarette packs are conveyed on the integral annular conveyor belt 1, the straight-line buffering of the smoke inlet segment 12 and the smoke outlet segment 13 can be implemented, while the annular buffering of the arc-shaped segment 11 of the spiral ring structure can also be implemented. This reduces space requirements and effectively increases the buffer length of the cigarette packs at the packaging inlet, improving the efficiency of mixing and packing standard and fine cigarettes.

[0033] In another specific example, the arc segment 11 is constructed as follows: Figure 3 The semi-circular conveyor structure shown has two sections arranged opposite each other, with an inclined smoke guide section 14 connecting the two arc-shaped sections 11, thus causing the two arc-shaped sections 11 to be longitudinally staggered. Specifically, the two arc-shaped sections 11 are referred to as the upper arc-shaped section 11a and the lower arc-shaped section 11b, respectively. One end of the upper arc-shaped section 11a forms an inlet connected to the smoke inlet section 12, and one end of the lower arc-shaped section 11b forms an outlet connected to the smoke inlet section 12. It is worth noting that the smoke inlet section 12, the smoke outlet section 13, and the smoke guide section 14 are all constructed as straight conveyor structures, and the smoke inlet section 12 and the smoke outlet section 13 extend in opposite directions along the tangent direction of the semi-circular conveyor structure. Thus, when different types of cigarettes are conveyed on the overall circular conveyor belt 1, the straight-line buffering of the smoke inlet section 12, the smoke outlet section 13, and the smoke guide section 14 can be performed, and the semi-circular buffering of the arc-shaped section 11 of the semi-circular conveyor structure can also be performed. Compared to the arc segment 11 of the spiral ring structure, the annular conveyor belt 1 of this embodiment, which includes two arc segments 11 and a smoke guide segment 14, has a longer buffer conveying length.

[0034] Furthermore, it should be noted that, to ensure stable transmission of the overall annular conveyor belt 1, the arc-shaped sections 11 of the two semi-annular conveyor structures are arranged horizontally, and preferably, the two arc-shaped sections 11 are constructed as active conveying components. For example... Figure 3 As shown, the active conveying component includes a roller 111, a conveyor belt 112, and a motor 113. The motor 113 drives the roller 111 to rotate, causing the conveyor belt 112 to circulate and convey the contents. Furthermore, the active conveying component also includes an inner ring housing and an outer ring housing for mounting the roller 111. The roller 111 is rotatably mounted between the inner ring housing and the outer ring housing, and the motor 113 is fixedly mounted on the outside of the outer ring housing, thus achieving a reasonable assembly of the overall structure. Accordingly, to ensure that the cigarette packs can be smoothly conveyed on the inlet section 12, outlet section 13, and guide section 14 of the linear conveying structure, the inlet section 12, outlet section 13, and guide section 14 are arranged according to… Figure 2 The arrangement shown is at least partially inclined, and the linear conveying structure includes rollers 111 and conveyor belts 112 for linear conveying under inclined guidance and the weight of the cigarette pack.

[0035] For example, the smoke suppressor 2 includes, as shown in the example, Figure 4 The transition section 21, gantry support 23, smoke-pressing cylinder 24, and smoke-pressing plate 22 are shown. Specifically, with... Figure 3Taking the arc segment 11 with two semi-circular conveying structures as an example, two smoke-pressing devices 2 are also provided, respectively arranged on the upstream side of the two arc segments 11. That is, one smoke-pressing device 2 (transition section 21) is arranged between the smoke inlet section 12 and the upper arc segment 11a, and the other smoke-pressing device 2 (transition section 21) is arranged between the smoke guide section 14 and the lower arc segment 11b. The gantry support 23 is fixedly installed along the width direction of the transition section 21 so that the cigarette pack can pass smoothly through the gantry support 23. The smoke-pressing cylinder 24 is fixed in the middle of the gantry support 23, and a smoke-pressing plate 22 is connected to the bottom of the telescopic end of the smoke-pressing cylinder 24 so that the smoke-pressing plate 22 can rise and fall longitudinally relative to the transition section 21 under the drive of the smoke-pressing cylinder 24. When the pressing plate 22 rises to its highest point relative to the transition section 21, a conveying channel is formed between the pressing plate 22 and the transition section 21, allowing cigarette packs (including standard cigarettes, standard slim cigarettes, and irregularly shaped cigarettes) to pass through. When the pressing plate 22 descends to its lowest point relative to the transition section 21, the pressing plate 22 abuts against the surface of the transition section 21, thereby preventing cigarette packs from passing through the transition section 21, i.e., blocking the conveying from the upstream side to the arc-shaped section 11.

[0036] For the conveying channel, a photoelectric sensor or a visual inspection camera can be optionally installed on the gantry bracket 23 to determine the type of cigarettes conveyed from the upstream side (smoke inlet section 12 or smoke guide section 14) when the arc section 11 is fully loaded. Based on the determined cigarette type, the lowering height of the pressing plate 22 driven by the pressing cylinder 24 is determined. For example, if the conveyed cigarettes are standard cigarettes, the lowering height of the pressing plate 22 driven by the pressing cylinder 24 is L1; if the conveyed cigarettes are standard slim cigarettes, the lowering height of the pressing plate 22 driven by the pressing cylinder 24 is L2, where L2 > L1.

[0037] It is worth noting that the cross-sectional shape of the cigarette pressing plate 22 is U-shaped, meaning that both sides of the cigarette pressing plate 22 bend upwards and extend to form extensions. This increases the blocking area of ​​the cigarette pressing plate 22 while reducing the overall weight of the cigarette pressing plate 22. Furthermore, the extensions are rounded to prevent the cigarette pressing plate 22 from causing damage to the cigarettes.

[0038] Furthermore, it should be noted that, to accommodate the transmission angle between the horizontal installation of the semi-circular conveying structure and the inclined installation of the linear conveying structure, it is preferable that a hinge 25 is connected between the telescopic end of the smoke-pressing cylinder 24 and the smoke-pressing plate 22. This allows the smoke-pressing plate 22 to swing relative to the transition section 21, and the swing center axis of the smoke-pressing plate 22 extends axially along the width direction of the transition section 21. This ensures that when the cigarette pack passes through the conveying channel between the smoke-pressing plate 22 and the transition section 21, the positioning angle of the smoke-pressing plate 22 can change with the conveying angle of the cigarette pack, thus ensuring that the cigarette pack can smoothly pass through the conveying channel and avoiding problems such as smoke blockage. Specifically, when the smoke-pressing plate 22 is parallel to the transition section 21, the swing angle of the smoke-pressing plate 22 is 0°. Preferably, the smoke-pressing plate 22 is set to swing flexibly within the range of -30° to 30°. Of course, in actual applications, the swing angle of the smoke-pressing plate 22 can be adaptively adjusted according to the transmission needs, and no specific limitation is made here.

[0039] In one specific example, the hinge 25 includes as follows Figure 4 The diagram shows a first hinge frame 251, a second hinge frame 252, and a rotating shaft 253. The first hinge frame 251 and the second hinge frame 252 are rotatably connected via the rotating shaft 253, and the first hinge frame 251 and the second hinge frame 252 are respectively fixedly connected to the smoke-pressing cylinder 24 and the smoke-pressing plate 22. Specifically, the first hinge frame 251 and the second hinge frame 252 are arranged in a U-shape to ensure the stability of the hinge connection between the smoke-pressing cylinder 24 and the smoke-pressing plate 22.
