Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a novel ZJ17 cigarette making machine tipping paper splicing joint detection device. Background Art
[0002] Tipping paper is an important raw and auxiliary material for cigarette production, and is responsible for meeting the process requirements of bonding and reinforcing cigarettes and filter rods. During normal operation of the equipment, the tipping paper currently in use will be automatically spliced with the tipping paper to be used without stopping the machine before the reel is exhausted. The splicing joints generated during the splicing process will be identified when passing through the tipping paper splicing detection device, and will be calibrated through the shift register in the control program. When the defective cigarettes reach the cigarette rejection station, they will be rejected by the reversing valve. At the same time, when the supplier of tobacco materials produces tipping paper, the reel will also have its own splicing joints (this is inevitable in the production process of tipping paper). This situation also requires the tipping paper splicing detection device in the winding equipment to be able to effectively identify and reject defective cigarettes.
[0003] The principle behind conventional paper splicing joint detection is to use a single semiconductor light source as the transmitter. When the wavelength of light passes through the object being tested, the receiver detects the presence of a splicing joint by observing changes in light intensity. A strong light intensity indicates a single-layered paper (qualified product), while a weak light intensity indicates a double-layered paper (unqualified product at the splicing joint).
[0004] A factory recently launched a new type of cigarette. The tipping paper is dark purple and features a laser-effect finish. This increases light absorbency, which in turn reduces the paper's light transmittance. This compromised the recognition rate of the existing tipping paper joint detection device. Production verification revealed that the existing joint detection device could misidentify or fail to identify tipping paper joints during the production process. These misidentifications increased the amount of defective cigarettes that could be rejected by the production machine, while the inability to effectively identify them increased the risk of defective products entering the consumer market.
[0005] Therefore, it is necessary to design a new ZJ17 cigarette machine tipping paper splicing joint detection device to detect the dark purple tipping paper splicing joints with laser effect. Utility Model Content

[0032] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0033] It should be noted that the structures, proportions, sizes, etc. depicted in the drawings of this specification are only used to match the contents disclosed in this specification for the understanding and reading of those familiar with this technology, and are not used to limit the conditions for the implementation of this utility model. Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in this utility model without affecting the efficacy and purpose of the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of this utility model. Changes or adjustments in their relative relationships should also be considered as the scope of the implementation of this utility model without substantially changing the technical content.
[0034] like Figures 1-10As shown, the utility model provides a new ZJ17 cigarette machine tipping paper splicing joint detection device (hereinafter referred to as the detection device), which is used in the cigarette machine; the splicing joint detection device includes a splicing joint detection component and a fixed bracket, and the splicing joint detection component is installed on the cigarette machine through the fixed bracket; the splicing joint detection component includes a shell 1, a light source module 2, a processor 3, an excitation light output module 4, and a receiving light input module 5, the light source module 2, the processor 3, the excitation light output module 4, and the receiving light input module 5 are all arranged in the shell 1, the light source module 2 is used to generate detection light; the light source module 2 is connected to the excitation light output module 4, and the detection light generated by the light source module 2 is emitted by the excitation light output module 4; the receiving light input module 5 is used to receive the detection light emitted by the excitation light output module 4; the detection light is emitted from the excitation light output module 4 and passes through the tipping paper in the cigarette machine and is received by the receiving light input module 5; the processor 3 is connected to the excitation light output module 4 and the receiving light input module 5, and is used to compare the light intensity difference between the detection light emitted by the excitation light output module 4 and the detection light received by the receiving light input module 5.
[0035] The utility model relates to a novel ZJ17 cigarette making machine tipping paper splice joint detection device. A light source module 2 generates detection light, which is emitted by an excitation light output module 4. The detection light then passes through the tipping paper and enters a receiving light input module 5. A processor 3 collects the intensity of the detection light emitted by the excitation light output module 4 and the intensity of the detection light received by the receiving light input module 5, and then compares the two. When the light intensity difference is a certain value, it indicates that there is no splice joint on the tipping paper and the tipping paper is qualified. When the light intensity difference is another value, it indicates that there is a splice joint on the tipping paper and the tipping paper is unqualified. The subsequent cigarette making machine's rejection function then rejects cigarettes wrapped in unqualified tipping paper, thereby ensuring that the cigarettes are qualified.
[0036] Preferably, Figure 1 As shown, the splice detection assembly further includes an optical signal amplifier 6, which is disposed within the housing 1. The optical signal amplifier 6 is connected to the light source module 2 and the excitation light output module 4. The detection light emitted by the light source module 2 is amplified by the optical signal amplifier 6 and then emitted by the excitation light output module 4. In this embodiment, the optical signal amplifier 6 is used to amplify the detection light. That is, the intensity of the detection light emitted by the excitation light output module 4 is increased, and therefore the intensity of the detection light received by the receiving light input module 5 is increased. The light intensity difference between the two is also increased, reducing the influence of the external environment on the light intensity difference, thereby improving the accuracy of the processor 3 in determining the light intensity difference.
[0037] Preferably, Figure 1As shown, the splice detection assembly also includes a light source power adjustment module 7, which is disposed within the housing 1. This module is connected to the light source module 2 and is used to adjust the power of the light source module 2. In this embodiment, changes in the light source power affect the penetrability of the detection light. A higher light source power results in a higher penetrability of the detection light; a lower light source power results in a lower penetrability of the detection light. When the light transmittance of the tipping paper is low, the light source power can be increased; when the light transmittance is high, the light source power can be decreased, making it suitable for detecting tipping paper of various specifications.
[0038] Preferably, Figure 1 、 Figure 6 、 Figure 8 As shown, the excitation light output module 4 includes an excitation fiber body 402, an excitation fiber input end 401, and an excitation fiber output end 403.

The detection light output by the excitation fiber output end 403 enters the receiving fiber body 502 from the receiving fiber input end 501 and is output from the receiving fiber output end 503; the excitation fiber input end 401 and the receiving fiber output end 503 are respectively connected to the processor 3.
[0039] In this embodiment, if Figure 1 、 Figure 2 As shown, a circuit board 10 is provided in the housing 1, and the above modules and electrical appliances are provided on the circuit board 10. A power line is also provided on the circuit board 10 for power supply.
[0040] Preferably, Figure 3 、 Figure 10 As shown, the fixed bracket includes a bracket body 8 and a bracket connecting seat 9. The bracket body 8 is fixedly connected to the bracket connecting seat 9, and the bracket connecting seat 9 is connected to the cigarette making machine. The bracket body 8 is provided with a U-shaped through-slot 801, an excitation fiber mounting hole 802, and a receiving fiber mounting hole 803. The excitation fiber mounting hole 802 and the receiving fiber mounting hole 803 are aligned and are respectively arranged on opposite sides of the U-shaped through-slot 801. In this embodiment, the bracket body 8 is cylindrical, and the length direction of the U-shaped through-slot 801 extends axially and the width direction extends radially, that is, the two opposite sides of the U-shaped through-slot 801 are parallel to the axial extension line of the U-shaped through-slot 801. The excitation fiber mounting hole 802 and the receiving fiber mounting hole 803 axially extend through the opposite sides of the U-shaped through-slot 801.
[0041] The purpose of the fixing bracket is: on the one hand, to fix the position of the excitation optical fiber body 402 and the receiving optical fiber body 502 in the fixing bracket, and on the other hand, to lock and fix them with the body 11.
[0042] In this application, there are several ways to connect the excitation light output module 4, the receiving light input module 5 and the fixed bracket:
[0043] The first connection method:
[0044] like Figure 3 、 Figure 4 As shown, the excitation fiber output end 403 is radially inserted into the excitation fiber mounting hole 802, with the excitation fiber body 402 positioned outside the fixed bracket. The receiving fiber input end 501 is radially inserted into the receiving fiber mounting hole 803, with the receiving fiber body 502 positioned outside the fixed bracket. The tipping paper passes through the U-shaped slot 801 (the receiving fiber input end 501 is not shown).
[0045] The second connection method:
[0046] like Figure 3 、 Figure 5 As shown, the bracket body 8 is further provided with an excitation fiber through-hole 804 and a receiving fiber through-hole 805. The excitation fiber through-hole 804 is connected with the excitation fiber mounting hole 802. The excitation fiber output end 403 passes through the excitation fiber through-hole 804 and is located in the excitation fiber mounting hole 802. The excitation fiber body 402 is located in the excitation fiber through-hole 804. The receiving fiber through-hole 805 is connected with the receiving fiber mounting hole 803. The receiving fiber input end 501 passes through the receiving fiber through-hole 805 and is located in the receiving fiber mounting hole 803. The receiving fiber body 502 is located in the receiving fiber through-hole 805.
[0047] In this embodiment, the excitation fiber insertion hole 804 extends axially within the bracket body 8 and is perpendicularly connected to the excitation fiber mounting hole 802. The receiving fiber insertion hole 805 also extends axially within the bracket body 8 and is perpendicularly connected to the excitation fiber mounting hole 802. Thus, a 90° bend is formed between the excitation fiber body 402 and the excitation fiber output end 403, and a 90° bend is formed between the receiving fiber body 502 and the receiving fiber input end 501.
[0048] The third connection method:
[0049] like Figure 7 、 Figure 9As shown, the excitation light output module 4 also includes an excitation light side lens 404, which is connected to the excitation fiber output end 403 and is used to convert the direction of the detection light; the receiving light input module 5 also includes a receiving light side lens 504, which is connected to the receiving fiber input end 501 and is used to convert the direction of the detection light; the bracket body 8 is also provided with an excitation fiber placement hole (the excitation fiber placement hole and the excitation fiber through-hole 804 can be used interchangeably), and a receiving fiber placement hole (the receiving fiber placement hole and the receiving fiber through-hole 805 can be used interchangeably), the excitation fiber placement hole is connected to the excitation fiber mounting hole 802, and after the excitation light side lens 404 passes through the excitation fiber placement hole, the output port of the excitation light side lens 404 is in the excitation fiber mounting hole 802; the receiving fiber placement hole is connected to the receiving fiber mounting hole 803, and after the receiving light side lens 504 passes through the receiving fiber placement hole, the input port of the receiving light side lens 504 is in the receiving fiber mounting hole 803.
[0050] Preferably, the three connection methods mentioned above can change the detection position according to the size of the tipping paper of different specifications, which is practical, flexible and convenient.
[0051] Preferably, Figure 1 、 Figure 3-Figure 5 As shown, a threaded hole 901 is provided in the bracket connecting base 9 for connecting to the cigarette making machine.
[0052] Preferably, Figure 10 As shown, the cigarette making machine includes a body 11, a first paper tray unfolding shaft 13, a second paper tray unfolding shaft 15, a conveying wheel 17, a rejection assembly, and several guide rollers 12. The first paper tray unfolding shaft 13 and the second paper tray unfolding shaft 15 are both installed on the body 11, and the tipping paper tray is sleeved on the first paper tray unfolding shaft 13 and the second paper tray unfolding shaft 15; the conveying wheel 17 is installed on the body 11 to pull the tipping paper; the splicing joint detection assembly is installed on the body 11 through a fixed bracket, and the splicing joint detection assembly detects the tipping paper; the rejection assembly rejects cigarettes with splicing joint defects.
[0053] In addition, the cigarette making machine also includes a control system, a coupler, a comparator, and a transmitter. The control system is connected to the processor 3. When the processor 3 detects a change in the light intensity difference, it determines that there is a splicing joint in the tipping paper at that location. At this time, the processor 3 feeds back information to the control system. After receiving the information, the control system converts the optical signal into an electrical signal through the coupler, comparator, and transmitter. Then, based on the distance between the U-shaped slot 801 and the rejection component and the length of the tipping paper required on a single cigarette, it determines which cigarette or adjacent cigarettes the splicing joint will be wrapped on. Then, the control system controls the rejection component to reject the cigarette.
[0054] The utility model relates to a new ZJ17 cigarette making machine tipping paper splicing joint detection device, the working steps are as follows:
[0055] S1: According to the attached Figures 1-10 , and the description of the above components to assemble the above components;
[0056] S2: After all components in step S1 are assembled, the two tipping paper trays are mounted on the first and second tray unwinding shafts 13 and 15, respectively. Each tipping paper tray is then connected to the conveyor wheel 17 via several guide rollers 12. The tipping paper passes through the U-shaped slot 801 of the fixed bracket and enters the subsequent cigarette packaging process. The packaged cigarettes are then conveyed to the rejection assembly and finally to the next process. The two tipping paper trays are the first tipping paper tray 14 and the second tipping paper tray 16, respectively, mounted on the first and second tray unwinding shafts 13 and 15, respectively.
[0057] S3: Start the splicing joint detection component and the conveying wheel 17. The conveying wheel 17 drives the tipping paper to be transported in the guide rollers 12 and the U-shaped groove 801. At this time, the light source module 2 generates a detection light, which is amplified by the optical signal amplifier 6 and enters the excitation light output module 4. Then, the excitation light output module 4 emits the detection light. The emitted detection light passes through the excitation fiber input end 401 and enters the excitation fiber main body 402. Finally, it is output from the excitation fiber output end 403 and irradiates the tipping paper in the U-shaped groove 801.
[0058] The detection light outputted from the exciting optical fiber output end 403 passes through the tipping paper and enters the receiving optical fiber input end 501 , then enters the receiving optical fiber body 502 , and is outputted from the receiving optical fiber output end 503 .
[0059] The processor 3 compares the light intensity at the excitation fiber input end 401 with the light intensity at the receiving fiber output end 503 to determine whether there is a splicing joint on the tipping paper;
[0060] S4: When the processor 3 detects the presence of a splicing joint, the processor 3 feeds back information to the control system. After receiving the information, the control system converts the optical signal into an electrical signal through the coupler, comparator, and transmitter. Then, based on the distance between the U-shaped slot 801 and the rejection component, and the length of the tipping paper required on a single cigarette, it is determined which cigarette or adjacent cigarettes the splicing joint will be wrapped around. The control system then controls the rejection component to reject the cigarette, thereby reducing the defective rate.

At the same time, it avoids defective products from entering the consumer market. In addition, the detection device can be applied to the production of cigarette tipping paper of different specifications (the texture and color of the tipping paper are different), meeting the effective identification of splicing joints of tipping paper of different specifications, and improving the use function of the ZJ17 cigarette machine unit.
[0062] Without changing the original functions of the equipment and the operating habits of the operators, this application can effectively identify the splicing joints generated during the splicing process and the splicing joints of the tipping paper itself encountered in normal production of the equipment after the current tipping paper is fully automatically spliced with the tipping paper to be used without stopping the machine before the reel is exhausted.
[0063] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
