Description

Technical Field

[0001] The utility model relates to a cigarette strip sorting and transmission device, belonging to the technical field of cigarette package sorting. Background Art

[0002] In cigarette production, cigarette cartons are usually placed on a conveyor belt to complete the cigarette packaging process. In order to improve the quality of cigarettes, it is necessary to inspect the cigarette cartons on the conveyor belt. At present, common defects of cigarette cartons include appearance defects and missing pack defects. The appearance defects of cigarette cartons include damaged transparent paper on the end face, misaligned teeth of the draw line of the carton box, offset of the trademark paper of the carton box, etc., which can be detected and identified by taking pictures of each side of the cigarette cartons and performing image processing, while the missing pack defects of cigarette cartons are mostly detected and identified by weighing the cigarette cartons or negative pressure testing. The detection methods of appearance defects and missing pack defects are both existing technologies, and relevant literature can be referred to, so they will not be repeated here.

[0003] In the production process of cigarette packaging, when defective cigarette cartons are detected on the conveyor belt, they need to be removed. According to the applicant's understanding, the commonly used method is to set a cigarette storage box for accommodating defective cigarette cartons on one side of the conveyor belt, and push the cigarette cartons into the cigarette storage box through a cigarette pushing device on the other side. However, since the cigarette storage box and the cigarette pushing device are both located on both sides of the conveyor belt, the occupied area is relatively large, and there is a large room for improvement in terms of both the layout of the production line and the cost. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a cigarette sorting and transmission device which occupies a small space.

[0005] In order to solve the above technical problems, one of the technical solutions proposed by the utility model is: a cigarette sorting and conveying device, comprising a first conveyor belt and a second conveyor belt arranged on a frame and adjacent to each other end to end;

[0006] The frame is provided with a fixed shaft and a support frame pivotally connected to the fixed shaft, the fixed shaft is provided with a driving wheel, the support frame is provided with a first passive wheel, the driving wheel is farther from the first transmission belt than the first passive wheel, and the second transmission belt is driven by the driving wheel and the first passive wheel;

[0007] The frame is provided with a flip driving mechanism for rotating the supporting frame around a fixed axis, and the second conveyor belt has a horizontal transmission state of being horizontally arranged, and a sorting transmission state of flipping upward or flipping downward; when the second conveyor belt is in the sorting transmission state, there is a gap between the first conveyor belt and the second conveyor belt that is larger than the cigarette strips, and a cigarette storage box is provided below the gap.

[0008] When the technical solution is in use, the first conveyor belt normally conveys cigarettes, and a detection device for detecting appearance defects and missing pack defects is provided on the first conveyor belt, which is a prior art. Under normal circumstances, the second conveyor belt is in a horizontal transmission state, and normal cigarettes are transmitted from the first conveyor belt to the next process through the second conveyor belt; when the detection device detects that defective cigarettes are about to be transmitted to the second conveyor belt, the second conveyor belt is driven by the flipping drive mechanism to flip upward or downward to the sorting transmission state. At this time, a gap larger than the cigarettes is formed between the first conveyor belt and the second conveyor belt, and the defective cigarettes fall from the gap into the cigarette storage box below, thereby completing the sorting and transmission of defective cigarettes.

[0009] In order to solve the above technical problems, the second technical solution proposed by the utility model is: a cigarette sorting and conveying device, comprising a first conveyor belt and a second conveyor belt arranged on a frame and adjacent to each other end to end;

[0010] The frame is provided with a fixed shaft and a support frame pivotally connected to the fixed shaft, the fixed shaft is provided with a driving wheel, the support frame is provided with a first passive wheel, the driving wheel is closer to the first transmission belt than the first passive wheel, and the second transmission belt is driven by the driving wheel and the first passive wheel;

[0011] The frame is provided with a flip driving mechanism for rotating the supporting frame around a fixed axis, and the second conveyor belt has a horizontal transmission state in which it is horizontally arranged, and a sorting transmission state in which it is flipped downward; when the second conveyor belt is in the sorting transmission state, a gap larger than the cigarette strips is formed between the end of the second conveyor belt away from the first conveyor belt and the subsequent process, and a cigarette storage box is provided below the gap.

[0012] The utility model divides the conveyor belt into a first conveyor belt and a second conveyor belt, and arranges the cigarette storage box below the first conveyor belt and the second conveyor belt instead of being located on both sides of the conveyor belt, thereby reducing the occupied area and omitting the cigarette pushing device, thereby reducing the production cost, transportation cost and use cost.

DETAILED DESCRIPTION

[0021] Embodiment 1:

[0022] This embodiment relates to a cigarette sorting and transmission device, such as Figure 1 and Figure 2 As shown, the machine comprises a first conveyor belt 2 and a second conveyor belt 3 which are arranged on a frame 1 and are adjacent to each other end to end. The conveying directions of the first conveyor belt 2 and the second conveyor belt 3 are consistent ( Figure 1 The middle cigarette is transmitted from left to right), and a cigarette storage box is provided below the junction of the first conveyor belt 2 and the second conveyor belt 3.

[0023] The frame 1 is provided with a fixed shaft 4 and a support frame 7 pivotally connected to the fixed shaft 4. The fixed shaft 4 and the support frame 7 are pivotally connected, for example, by a metal sleeve, preferably by a bearing. A driving wheel 5 is installed on the fixed shaft 4, and a first passive wheel 6 is installed on the support frame 7. The second transmission belt 3 is driven by the driving wheel 5 and the first passive wheel 6. The driving wheel 5 is farther from the first transmission belt 2 than the first passive wheel 6, so that auxiliary equipment such as the driving motor and reducer of the driving wheel 5 can be installed conveniently. In this way, when the support frame 7 is turned over, the turning force required is small.

[0024] The frame 1 is provided with a flip driving mechanism for rotating the support frame 7 around the fixed axis 4. The second conveyor belt 3 has a horizontal transmission state in which the horizontal transmission is arranged horizontally, and a sorting transmission state in which the second conveyor belt 3 is flipped upward. Figure 1 As shown, at this time, there may be no gap between the first conveyor belt 2 and the second conveyor belt 3, or the gap is smaller than the size of the cigarette 13; when the second conveyor belt 3 is in the sorting and transmission state, as shown in FIG. Figure 3 As shown, at this time, there is a gap between the first conveyor belt 2 and the second conveyor belt 3 that is larger than the cigarette 13 .

[0025] The flip driving mechanism can be realized by various existing technologies, such as a crank rocker mechanism with the support frame 7 as a rocker. Figure 1 and Figure 2 As shown, the flipping drive mechanism in this embodiment includes a cylinder 16 arranged on the frame 1, the cylinder body of the cylinder 16 is hinged to the frame 1 (not shown in the figure), and the piston rod of the cylinder 16 is hinged to the support frame 7, so that the support frame 7 can be flipped upward by the extension and contraction of the piston rod of the cylinder 16, thereby driving the second conveyor belt 3 to flip upward.

[0026] like Figure 1-Figure 3 As shown, in this embodiment, the conveyor belt is divided into a first conveyor belt 2 and a second conveyor belt 3, and the cigarette storage box is set below the first conveyor belt 2 and the second conveyor belt 3, and is no longer located on both sides of the conveyor belt. When in use, the first conveyor belt 2 transmits the cigarette strips 13 in a time sequence, generally transmitting 20-40 cigarette strips 13 per minute. Under normal circumstances, the second conveyor belt 3 is in a horizontal transmission state, and normal cigarette strips are transmitted from the first conveyor belt 2 to the next process through the second conveyor belt 3; when the detection device detects that the defective cigarette strips are about to be transmitted to the second conveyor belt 3, the second conveyor belt 3 is driven by the flipping drive mechanism to flip upward to the sorting transmission state. At this time, a gap larger than the cigarette strips 13 is formed between the first conveyor belt 2 and the second conveyor belt 3, and the defective cigarette strips 13 fall from the gap and enter the cigarette storage box below, thereby completing the sorting and transmission of the defective cigarette strips 13. How the detection device detects and locates defective cigarette strips is a prior art. The position of the cigarette strips is usually judged according to the time sequence, and reference can be made to relevant literature.

[0027] In addition, this embodiment omits the cigarette pushing device used in the prior art for sorting defective cigarette cartons, thereby reducing the occupied area and lowering the production cost, transportation cost and use cost.

[0028] This embodiment can also be improved as follows:

[0029] 1) If Figure 2 As shown, a limit block 18 is provided below the support frame 7, and a limit stopper 19 cooperating with the limit block 18 is provided on the frame 1. When the limit block 18 abuts against the limit stopper 19, the second conveyor belt 3 is in a horizontal transmission state. At this time, the limit stopper 19 supports and fixes the support frame 7, thereby improving reliability. Preferably, a hydraulic buffer 17 matching the limit block 18 is provided on the frame 1. When the support frame 7 drives the second conveyor belt 3 to flip upward to the sorting transmission state, when it is necessary to return to the position, the limit block 18 gradually approaches the limit stopper 19, and the hydraulic buffer 17 buffers the limit block 18 to prevent the limit block 18 from hard collision with the limit stopper 19 and vibration.

[0030] 2) Because there are two types of defective cigarettes, the cigarette storage box is divided into a first cigarette storage box 9 and a second cigarette storage box 10 in this embodiment. Figure 1 and Figure 3 As shown, a cigarette conveying channel (not shown in the figure) is provided between the gap between the first conveyor belt 2 and the second conveyor belt 3 and the cigarette storage box. A switch is provided on the cigarette conveying channel. The switch has a first state in which the cigarette conveying channel is connected to the first cigarette storage box 9 and closed to the second cigarette storage box 10, and a second state in which the cigarette conveying channel is closed to the first cigarette storage box 9 and connected to the second cigarette storage box 10. In this way, when the detection device detects a cigarette carton with appearance defects, under the action of the switch, the cigarette conveying channel is connected to the first cigarette storage box 9, and the defective cigarette carton enters the first cigarette storage box 9; when a cigarette carton with missing pack defects is detected, the cigarette conveying channel is connected to the second cigarette storage box 10, and the defective cigarette carton enters the second cigarette storage box 10.

[0031] The switch can adopt a variety of existing implementations. Preferably, the first smoke storage box 9 and the second smoke storage box 10 are separated by a partition 11, and the switch includes a flap 12 located above the partition 11, and the flap 12 is hinged to the partition 11; when the switch is in a first state, the flap 12 flips toward the second smoke storage box 10, and when the switch is in a second state, the flap 12 flips toward the first smoke storage box 9, so that the structure is simpler.

[0032] 3) If Figure 1-Figure 3 As shown, in order to facilitate normal cigarettes to enter the next process, a third conveyor belt 8 is provided at one end of the second conveyor belt 3 away from the first conveyor belt 2, and a second passive wheel 15 is provided on the frame 1. The third conveyor belt 8 is driven by the active wheel 5 and the second passive wheel 15. At this time, normal cigarettes enter the next process from the first conveyor belt 2 through the second conveyor belt 3 and the third conveyor belt 8. Through the above arrangement, the length of the second conveyor belt 3 can be made very short without affecting the cigarettes 13 entering the next process. Therefore, the size of the support frame 7 can be reduced, so that the cylinder 16 can flip the support frame 7 by applying a small force, and the transmission directions of the first conveyor belt 2, the second conveyor belt 3 and the third conveyor belt 8 remain consistent.

[0033] Embodiment 2:

[0034] The difference between this embodiment and the first embodiment is that: Figure 4 As shown, when the flipping drive mechanism drives the support frame 7 to drive the second conveyor belt 3 to switch from the horizontal conveying state to the sorting conveying state, the second conveyor belt 3 flips downward, while the embodiment 1 flips upward. Except for this, the working process is basically the same as the embodiment 1.

[0035] In addition, the hydraulic buffer 17 in the first embodiment is located below the second conveyor belt 3 , while the hydraulic buffer 17 in this embodiment is located above the second conveyor belt 3 .

[0036] Embodiment three:

[0037] The difference between this embodiment and the second embodiment is that: Figure 5 and Figure 6 As shown, the driving wheel 5 is closer to the first conveyor belt 2 than the first passive wheel 6. At this time, the gap for sorting defective cigarettes is located at the end of the second conveyor belt 3 away from the first conveyor belt 2. In the second embodiment, the driving wheel 5 is farther from the first conveyor belt 2 than the first passive wheel 6. At this time, the gap for sorting defective cigarettes is close to the first conveyor belt 2.

[0038] In this embodiment, the flip driving mechanism is as follows: Figure 6 As shown, the piston rod of the cylinder 16 is extended and retracted to drive the support frame 7 to flip downward, thereby driving the second conveyor belt 3 to flip downward. When the second conveyor belt is in the sorting and conveying state, a gap larger than the cigarette strip is formed between the end of the second conveyor belt away from the first conveyor belt and the subsequent process.
