Description

Technical Field

[0001] The present invention relates to the technical field of wrapping machinery, and in particular to a cigarette and liner paper rejecting and storing device, a ZB47 packaging machine, and a rejecting and storing method. Background Art

[0002] In the field of cigarette packaging, the ZB47 packaging machine, as a widely used high-speed cigarette packaging equipment, undertakes the important task of efficiently packaging qualified cigarette groups.

[0003] During the packaging process of the existing ZB47 packaging machine, a layer of paraffin oil is typically applied to the inner liner to enhance its ductility and allow it to more smoothly conform to the shape of the cigarette group during folding and packaging. While this practice effectively improves packaging efficiency and quality, it also presents a pressing problem: because the paraffin oil coating on the inner liner means that if the cigarette group does not meet the packaging requirements, the group will be rejected for recycling along with the inner liner. This can easily cause the cigarettes to come into contact with the inner liner, resulting in the paraffin oil contaminating the tobacco, creating greasy cigarettes. These greasy cigarettes, contaminated by the paraffin oil, cannot be recycled, resulting in a waste of cigarette resources.

[0004] It can be seen that when the existing ZB47 packaging machine processes unqualified cigarette groups, due to the characteristics of the inner liner paper coated with paraffin oil, the cigarettes are easily contaminated during the rejection process, and thus the effective recycling of resources cannot be achieved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problem of paraffin oil on the liner paper contaminating the cigarettes when the ZB47 packaging machine processes unqualified cigarette groups, and to provide a cigarette and liner paper rejection and storage device. The rejection and storage device can separately transport and store unqualified cigarette groups and corresponding liner papers to avoid contact between the cigarettes and the liner paper.

[0006] In order to achieve the above-mentioned object, the first aspect of the present invention provides a device for rejecting and storing cigarettes and liner paper, comprising: The rejector is used to remove unqualified cigarettes from the cigarette conveyor belt; The second detection module is used to detect the quality of the cigarette group on the cigarette conveyor belt. The detection position of the second detection module is located upstream of the rejection position of the rejector; A cigarette channel, the cigarette channel having an inlet and an outlet, the inlet being used to receive unqualified cigarette groups rejected from the cigarette conveyor belt; The conveying structure includes a first conveying part and a second conveying part separated from each other, and the first conveying part receives and conveys the unqualified cigarette group discharged from the outlet; The second conveying track is used to receive the inner liner paper detached from the second adsorption cylinder and convey the inner liner paper to the second conveying part, where the inner liner paper corresponds to the unqualified cigarette group; A first storage box, which is provided at the end of the first conveying portion and is used to receive unqualified cigarette groups; The second storage box is arranged at the end of the second conveying part and is used for receiving the liner paper.

[0007] In some embodiments, the conveying structure includes a separating conveyor belt and a separator, wherein the separator is independent of the separating conveyor belt and is fixedly arranged. The separator extends along the conveying direction of the separating conveyor belt and divides the separating conveyor belt into a first conveying portion and a second conveying portion.

[0008] In some embodiments, along the conveying direction of the separation conveyor belt, a guide member for guiding and separating the cigarettes and the liner paper is fixed on at least one end of the separator.

[0009] In some embodiments, the inlet is positioned higher than the outlet.

[0010] In some embodiments, the spacer is n-type.

[0011] Preferably, a side opening is provided on a side of the partition for communicating with the outlet.

[0012] In some embodiments, a brush is fixedly provided on the side of the separator facing the separation conveyor belt, and the brush contacts the separation conveyor belt.

[0013] The application of the above technical solution of the present invention to a device for rejecting and storing cigarettes and liner paper has the following effects: The unqualified cigarette groups are removed on the cigarette conveyor belt to avoid the liner paper from packaging the unqualified cigarette groups. This makes it easier to transport and store the unqualified cigarette groups separately from the liner paper that should be used to package the group of cigarettes, avoiding the cigarettes being contaminated by oil stains and unable to be recycled, thus saving resources.

[0014] A second aspect of the present invention provides a ZB47 packaging machine, comprising the cigarette and liner paper rejecting and storing device as described above.

[0015] In some embodiments, the ZB47 packaging machine includes a rotating frame and several pushing pieces, the pushing pieces include a first pushing piece, the first pushing piece is used to push the qualified cigarette group on the cigarette conveyor belt into the slot of the rotating frame, and the pushing position of the first pushing piece is located downstream of the rejection position of the rejector.

[0016] In some embodiments, the pushing direction of the first pusher is opposite to the rejecting direction of the rejector.

[0017] A third aspect of the present invention provides a method for rejecting and storing cigarettes and liner paper using the above-mentioned device for rejecting and storing cigarettes, comprising the following steps: Get the rejection signal and run the conveying structure after the delay time t0; After receiving the rejection signal, when the cigarette group to be rejected reaches the rejection station, the rejector will operate and remove the cigarette group to be rejected from the cigarette conveyor belt; The conveying structure starts to operate after the rejection signal and the duration t0 has passed. The conveying structure stops after running for t1, and t1 is the maximum value of t2 and t3; Among them, t2 is the time length that the first conveying part conveys the cigarettes from the receiving area to the first storage box, and t3 is the time length that the second conveying part conveys the liner paper from the receiving area to the second storage box.

[0021] The following is a detailed description of the specific embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0022] First, the structure and working principle of the ZB47 packaging machine in the prior art are further explained.

[0023] The ZB47 packaging machine operates in four main phases: liner paper 1 conveying, cigarette group 2 conveying, cigarette group 2 and liner paper 1 packaging inspection, and cigarette group 2 rejection. Liner paper 1 conveying and cigarette group 2 conveying occur simultaneously.

[0024] Combined with attachment Figure 1 and attached Figure 2 As shown, the ZB47 packaging machine includes a cigarette conveyor belt 4, several pushers (not shown), a rotating frame 5, a packaging wheel 24, a packaging module 500, a first detection module 300, a pressing roller 25, a cutting module 400, a first suction cylinder 21, a second suction cylinder 22, and a first conveyor track 27. The pushers are primarily used to propel the movement of the cigarette group 2. During the entire packaging process, the cigarette group 2 is frequently transferred, so the number and position of the pushers are set accordingly based on the transfer requirements of the cigarette group 2.

[0025] The steps of the inner liner paper 1 conveying process are as follows: 1. The paper tape 26 is transported between the pressing roller 25 and the first adsorption cylinder 21 , and the cutting module 400 cuts the paper tape 26 and cuts out the liner paper 1 of appropriate length.

[0026] 2. The cut liner paper 1 is adsorbed on the surface of the first adsorption cylinder 21 and rotates with the first adsorption cylinder 21 .

[0027] 3. After the inner lining paper 1 on the first adsorption cylinder 21 approaches the second adsorption cylinder 22, the first adsorption cylinder 21 cancels its adsorption effect on the inner lining paper 1 while the second adsorption cylinder 22 increases its adsorption effect on the inner lining paper 1. The inner lining paper 1 separates from the first adsorption cylinder 21 and is adsorbed on the surface of the second adsorption cylinder 22 and rotates with the second adsorption cylinder 22.

[0028] 4. After the inner lining paper 1 on the second adsorption cylinder 22 approaches the first conveying track 27, the second adsorption cylinder 22 cancels its adsorption effect on the inner lining paper 1, and the inner lining paper 1 leaves the second adsorption cylinder 22 and moves along the first conveying track 27 under the action of gravity.

[0029] Typically, the surfaces of the first adsorption cylinder 21 and the second adsorption cylinder 22 are covered with tiny pores, and a vacuum pump is installed inside the cylinders. The vacuum pump's adsorption action penetrates the pores, adsorbing the inner liner 1 onto the cylinder surfaces and causing the cylinders to rotate. When the vacuum pump releases its adsorption action, the adsorption action on the inner liner 1 is canceled.

[0030] In other packaging machines, the liner paper 1 is also adhered to the drum surface by mechanical clamping methods such as mechanical claws or electrostatic adsorption methods and rotates with the drum. The mechanical claws are loosened or the static electricity is released, allowing the liner paper 1 to separate from the drum surface, which is equivalent to the first adsorption cylinder 21 and the second adsorption cylinder 22 canceling their adsorption effect on the liner paper 1.

[0031] The steps of the cigarette group 2 conveying process are as follows: 1. The cigarette conveyor belt 4 conveys the stacked cigarette groups 2. To prevent the cigarette groups 2 from being scattered, a mold box 3 is set on the cigarette conveyor belt 4 to keep the cigarette groups 2 in three layers, with seven, six, and seven cigarettes in order from top to bottom, for a total of twenty cigarettes.

[0032] 2. After the cigarette group 2 on the cigarette conveyor belt 4 is in place, the provided pushing member pushes the cigarette group 2 into the right slot of the rotating frame 5.

[0033] 3. The rotating frame 5 rotates to rotate the cigarette group 2 in the slot and drives it to the left.

[0034] The steps for testing cigarette group 2 and liner paper 1 packaging are as follows: First, the pusher pushes the cigarette group 2 located in the left slot of the rotating frame 5 to the left into the slot of the packaging wheel 24. During this pushing process, the liner paper 1 moving on the first conveyor track 27 is located between the rotating frame 5 and the packaging wheel 24. Therefore, as the cigarette group 2 is pushed from the rotating frame 5 to the packaging wheel 24, the liner paper 1 pre-packages the cigarette group 2 and then enters the slot of the packaging wheel 24 along with the cigarette group 2.

[0035] 2. The packaging wheel 24 rotates and drives the cigarette group 2 and the liner paper 1 to rotate. During the rotation, the liner paper 1 completely wraps the cigarette group 2 through the packaging module 500. At the same time, the first detection module 300 performs quality inspection on the cigarette group 2 packaged on the packaging wheel 24.

[0036] The steps for rejecting cigarette group 2 are as follows: If the quality of the cigarette group 2 packed on the packaging wheel 24 meets the requirements, the pusher pushes the packed cigarette group 2 onto the conveyor belt and transports it to the next process. If the quality of the cigarette group 2 packed on the packaging wheel 24 does not meet the requirements, the pusher pushes the packed cigarette group 2 together with the liner paper 1 onto another conveyor belt and transports it to a rejection box for recycling. At this time, oily cigarettes are more likely to appear.

[0037] In the present invention, the existing ZB47 packaging machine is improved to solve the above problems. The first aspect of the present invention provides a device for removing and storing cigarettes and liner paper 1. Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, the cigarette and liner paper 1 rejection and storage device includes a rejector 8, a second detection module 600, a cigarette channel 11, a conveying structure 100, a second conveying track 23, a first storage box 14 and a second storage box 15.

[0038] Specifically, the rejector 8 is used to remove cigarette groups 2 with missing cigarettes, empty cigarettes, or other unqualified cigarettes from the cigarette conveyor belt 4. Since the rejector 8 essentially functions to push the cigarette group 2 from the mold box 3 on the cigarette conveyor belt 4, it has the same function as a pusher. Therefore, the structure of the rejector 8 can be the same as that of existing pushers and will not be described in detail here.

[0039] The second inspection module 600 is used to inspect the quality of cigarette groups 2 on the cigarette conveyor belt 4. The second inspection module 600 is located upstream of the rejector 8. The second inspection module 600 primarily detects cigarette groups 2 for quality issues such as missing cigarettes or empty cigarettes. If a quality issue is detected in a cigarette group 2, a rejection signal is issued and the rejector 8 is controlled to reject the corresponding unqualified cigarette group 2.

[0040] The cigarette channel 11 has an inlet 11a and an outlet 11b. The inlet 11a is used to receive unqualified cigarette groups 2 rejected from the cigarette conveyor belt 4. Since the cigarette groups 2 are stacked on the cigarette conveyor belt 4, they will be scattered into several cigarettes after being rejected from the cigarette conveyor belt 4. Therefore, the cigarette groups 2 will eventually be discharged from the outlet 11b in a scattered state.

[0041] The conveying structure 100 includes a first conveying portion 12 and a second conveying portion 13 separated from each other. The first conveying portion 12 receives and conveys cigarettes discharged from the outlet 11b, and the first storage box 14 is provided at the end of the first conveying portion 12 for receiving cigarettes.

[0042] The second conveying track 23 is used to receive the inner lining paper 1 detached from the second adsorption cylinder 22 and convey the inner lining paper 1 to the second conveying part 13. The second conveying part 13 receives and conveys the inner lining paper 1. The second storage box 15 is provided at the end of the second conveying part 13 for receiving the inner lining paper 1.

[0043] In the present invention, the action of removing the cigarette groups 2 with unqualified quality such as missing cigarettes and empty cigarettes is set during the conveying process of the cigarette conveyor belt 4. The cigarette groups 2 are removed before being packaged to avoid contact between the cigarettes and the lining paper 1. Finally, the cigarettes and the lining paper 1 are transported and stored separately, which is convenient for the recycling and reuse of the cigarettes and the lining paper 1 and saves resources.

[0044] Combined with attachment Figure 7 As shown, the operating principle of the cigarette and liner paper 1 rejection and storage device of the present invention is as follows: the rejector 8 rejects unqualified cigarette groups 2 from the cigarette conveyor belt 4. The rejected cigarette groups 2 fall through the cigarette channel 11 into the first conveying section 12. The first conveying section 12 conveys the unqualified cigarettes to the first storage box 14 for storage. At the same time, the second suction cylinder 22 removes its suction force on the liner paper 1 that should have been used to package the unqualified cigarette group 2, causing the liner paper 1 to fall along the second conveying track 23 and onto the second conveying section 13. Finally, the second conveying section 13 conveys the liner paper 1 to the second storage box 15 for storage.

[0045] It should be noted that the inner liner paper 1 is pre-cut to the appropriate size before packaging, and the inner liner paper 1 corresponds one-to-one with the cigarette group 2. When an unqualified cigarette group 2 appears on the cigarette conveyor belt 4, the inner liner paper 1 that should have been used to package the cigarette group 2 is no longer used for packaging, but instead falls directly onto the second conveying section 13. The second conveying section 13 then conveys the inner liner paper 1 to the second storage box 15 for storage and easy recycling.

[0046] If the liner paper 1 originally intended for packaging the cigarette group 2 is still to be used for packaging, the first adsorption drum 21 and the second adsorption drum 22 used to convey the liner paper 1 need to reduce their rotational speed to reduce the conveying speed of the liner paper 1. Ultimately, the liner paper 1 originally intended for packaging the cigarette group 2 is used to package the next cigarette group 2, increasing the control cost of the conveying process of the liner paper 1. Therefore, in the present invention, the liner paper 1 originally intended for packaging unqualified cigarette groups 2 is directly dropped onto the second conveying portion 13. This design eliminates the need to adjust the conveying frequency of the liner paper 1 conveyor, saving control costs.

[0047] In some preferred embodiments, Figure 6 and attached Figure 9 And attached Figure 8 and attached Figure 10 As shown, the conveying structure 100 includes a separation conveyor belt 200 and a separator 16. The separator 16 is independent of the separation conveyor belt 200 and is fixedly arranged. The separator 16 extends along the conveying direction of the separation conveyor belt 200 and separates the separation conveyor belt 200 into a first conveying portion 12 and a second conveying portion 13. In this embodiment, the first conveying portion 12 for conveying cigarettes and the second conveying portion 13 for conveying the liner paper 1 are the same conveyor belt. Compared with independently setting up two sets of conveyor belts to convey cigarettes and liner paper 1 respectively, the structure in this embodiment is more compact, has greater space utilization, and has fewer power sources. The separator 16 is set to separate the first conveying portion 12 and the second conveying portion 13 to prevent the cigarettes from contacting the liner paper 1. The separator 16 can be directly fixedly installed on the body of the packaging machine.

[0048] In some preferred embodiments, Figure 11 As shown, a guide 17 for guiding the separation of cigarettes and liner paper 1 is fixedly provided on at least one end of the separator 16 along the conveying direction of the separation conveyor belt 200. During operation, the liner paper 1 not used for packaging falls directly onto the separation conveyor belt 200 and is relatively scattered. The guide 17, which is provided at the upstream end of the separator 16 on the conveying direction of the separation conveyor belt 200, is used to guide the liner paper 1 with a larger scattered area to the second conveying section 13, thereby preventing the liner paper 1 from entering the first conveying section 12 and mixing with the cigarettes.

[0049] Furthermore, the cigarettes and liner paper 1 are conveyed on the same separating conveyor belt 200, so the first storage box 14 and the second storage box 15 are located relatively close together. A guide member 17, located on the downstream end of the separating conveyor belt 200 and attached to the partition 16, further separates the liner paper 1 and cigarettes at the end of the separating conveyor belt 200, preventing them from falling into the same storage box.

[0050] In some preferred embodiments, Figure 6 and attached Figure 8 As shown, the inlet 11a is positioned higher than the outlet 11b, allowing cigarettes entering the cigarette passage 11 to fall onto the first conveying section 12 of the separation conveyor 200 under the action of gravity, eliminating the need for additional conveying components. Generally, the inlet 11a of the cigarette passage 11 is larger than the outlet 11b. The wider inlet 11a facilitates the ejector 8 to push cigarettes into the cigarette passage 11, while the narrower outlet 11b facilitates the concentrated delivery of cigarettes onto the first conveying section 12 of the separation conveyor 200, preventing them from being scattered.

[0051] In some preferred embodiments, Figure 6 and attached Figure 9 As shown, the separator 16 is n-shaped. The n-shaped separator 16 cooperates with the separating conveyor 200 to form a channel, further preventing cigarettes from falling off the separating conveyor 200 during transport. In a further preferred embodiment, the separator 16 has a side opening 18 that connects to the outlet 11b, ensuring that all cigarettes in the cigarette channel 11 can enter the channel formed by the n-shaped separator 16 and the separating conveyor 200.

[0052] In some preferred embodiments, Figure 9 and attached Figure 10 As shown, a brush 19 is fixedly provided on the side of the separator 16 facing the separation conveyor belt 200, and the brush 19 contacts the separation conveyor belt 200. The function of the separator 16 is to separate the conveying space on the separation conveyor belt 200 into a first conveying portion 12 and a second conveying portion 13, and the separator 16 is independent of the separation conveyor belt 200 and is fixedly arranged. In order to avoid friction between the separator 16 and the separation conveyor belt 200, which causes wear of the separation conveyor belt 200 and the separator 16, a gap is generally required between the separator 16 and the surface of the separation conveyor belt 200. The existence of the gap creates a hidden danger of contact between the cigarettes in the first conveying portion 12 and the inner lining paper 1 in the second conveying portion 13, and the provision of the brush 19 eliminates the gap and avoids severe friction between the separator 16 and the separation conveyor belt 200.

[0053] The second aspect of the present invention provides a ZB47 packaging machine, Figure 3 and attached Figure 5 The ZB47 packaging machine includes a cigarette and liner paper 1 rejection and storage device as described in any of the above embodiments. In actual use, the rejector 8, cigarette channel 11, conveying structure 100, first storage box 14, and second storage box 15 of the cigarette and liner paper 1 rejection and storage device can be directly installed on the body of the ZB47 packaging machine.

[0054] In some preferred embodiments, the ZB47 packaging machine includes a rotating frame 5 and a plurality of pushers, the pushers including a first pusher 28, the first pusher 28 being used to push the qualified cigarette group 2 on the cigarette conveyor belt 4 into the slot of the rotating frame 5, and the pushing position of the first pusher 28 is located downstream of the rejection position of the rejector 8. Specifically, as shown in the attached figure, Figure 4As shown, the cigarette groups 2 on the cigarette conveyor belt 4 first pass through the reject position where the rejector 8 is located, and then pass through the cigarette pushing position where the first pusher 28 is located. This design prioritizes the rejection of unqualified cigarette groups 2 on the cigarette conveyor belt 4, reducing the possibility of the first pusher 28 pushing unqualified cigarette groups 2 into the packaging wheel 24, thereby ensuring the quality of cigarette packaging. Furthermore, since both the first pusher 28 and the rejector 8 function to push the cigarette groups 2 out of the mold box 3 on the cigarette conveyor belt 4, the rejector 8 can adopt the same structure as the first pusher 28.

[0055] In some preferred embodiments, as shown in the attached Figure 4 As shown, the pushing direction of the first pusher 28 is opposite to the rejecting direction of the rejector 8. Specifically, the first pusher 28 and the rejector 8 both push the cigarette group 2 to push the cigarette group 2 out of the mold box 3. If the direction in which the first pusher 28 pushes the cigarette group 2 is the same as the direction in which the rejector 8 rejects the cigarette group 2, the first pusher 28 and the rejector 8 need to be arranged on the same side of the cigarette conveyor belt 4. If the direction in which the first pusher 28 pushes the cigarette group 2 is opposite to the direction in which the rejector 8 rejects the cigarette group 2, the first pusher 28 and the rejector 8 need to be arranged on different sides of the cigarette conveyor belt 4, which will result in fewer installation restrictions for the first pusher 28 and the rejector 8 and greater space utilization.

[0056] The third invention of the present invention provides a method for rejecting and storing cigarettes, using the cigarette and liner paper 1 rejecting and storing device as described in any of the above embodiments. The method comprises the following steps: Obtain the rejection signal and then operate the conveying structure 100 after the delay time t0; After receiving the rejection signal, when the cigarette group 2 to be rejected reaches the rejection station, the rejector 8 operates and rejects the cigarette group 2 to be rejected on the cigarette conveyor belt 4; After the rejection signal is obtained and the time duration t0 has passed, the conveying structure 100 starts to operate. The conveying structure 100 stops after running for t1, where t1 is the maximum value between t2 and t3; Among them, t2 is the time length that the first conveying part 12 conveys the cigarette from receiving to the first storage box 14, and t3 is the time length that the second conveying part 13 conveys the liner paper 1 from receiving to the second storage box 15.

[0057] Specifically, the rejection signal is obtained and the conveying structure 100 is operated after a delay of t0, giving the rejector 8 operating time, the cigarette moving time in the cigarette channel 11 and the liner paper 1 falling time, and reducing the no-load operation of the conveying structure 100.

[0058] In addition, the running time t1 of the conveying structure 100 takes the maximum value of t2 and t3, t2 is the time length that the first conveying part 12 conveys the cigarettes from receiving to the first storage box 14, and t3 is the time length that the second conveying part 13 conveys the liner paper 1 from receiving to the second storage box 15, to ensure that the cigarettes and the liner paper 1 can be completely delivered to the first storage box 14 and the second storage box 15, and to avoid the cigarettes and the liner paper 1 from piling up on the conveying structure 100.

[0059] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0061] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
