Description

Technical Field

[0001] The utility model relates to the technical field of coil paper joint detection, in particular to a coil paper joint detection device. Background Art

[0002] During cigarette production, different types of paper are used for cigarette box packaging, filter production, and tobacco rod production. To meet daily operational needs, these different types of paper are typically installed on different reels. The paper used to wrap the tobacco rods is known as the reel paper. In practice, when the reel paper on the reel turntable is almost empty, it is typically replaced and spliced ​​with pre-installed new reels to ensure a timely supply of reels to the equipment and a stable tobacco rod production process.

[0003] During the paper splicing process on the paper reel, in addition to the paper splicing joints that occur when the paper is replaced, the paper itself also has original joints due to the production process. The security of these two joints plays a vital role in the stable operation of the equipment. Existing methods for detecting paper splices generally use the equipment's built-in detection probe. However, because the original joint process is more advanced than the paper splicing process, this detection probe can only accurately detect the paper splicing joints during paper replacement. It is not accurate enough to detect the original joints on the paper reel. This leads to inaccurate detection results for the spliced ​​joints on the paper reel, which in turn affects the quality of the cigarettes.

[0004] Therefore, it is necessary to improve and design the detection structure for detecting the paper joints on the paper turntable to solve the problem that when detecting the paper joints on the paper turntable, the existing detection method uses the detection probe provided by the equipment, which can only accurately detect the spliced ​​joints when the paper is replaced, and the detection accuracy of the original joints on the paper is not enough. Utility Model Content

[0005] The purpose of the utility model is to provide a paper roll joint detection device to solve the problem that when detecting the paper roll joints on the paper roll turntable, the existing detection method uses the detection probe provided by the equipment to detect, which can only accurately detect the spliced ​​joints when the paper roll is replaced, and the detection accuracy of the original joints on the paper roll is not enough.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] Coil joint detection device, including

[0008] Photoelectric sensor, the photoelectric sensor includes a light projector and a light receiver, and the detection channel of the splice paper is between the light projector and the light receiver;

[0009] The optical fiber amplifier, the light projector and the light receiver are respectively connected to the optical fiber amplifier, and the optical fiber amplifier is provided with a display screen for displaying the light sensitivity value.

[0010] Furthermore, it also includes a connecting plate, the side wall of which is provided with a through slot for paper to pass through, the through slot divides the lower half of the connecting plate into a first mounting position and a second mounting position, the first mounting position is detachably provided with a projector, and the second mounting position is detachably provided with a light receiver.

[0011] Furthermore, the through slot for the paper supply tray to pass through is communicated with the detection passage, and the edge of the through slot for the paper supply tray to pass through is covered with a flexible layer for preventing scratching.

[0012] Furthermore, it also includes an optical fiber; the light projector and the light receiver are respectively connected to the optical fiber amplifier through the optical fiber.

[0013] Furthermore, it also includes a power signal line; the first end of the power signal line is connected to the optical fiber amplifier, and the second end of the power signal line is respectively connected to the cigarette making machine power supply and the controller that controls the action of the cigarette removal mechanism.

[0014] Furthermore, the first end of the power signal line is connected to one end of the connecting plug, and the other end of the connecting plug is plugged into the plug interface on one side wall of the optical fiber amplifier.

[0015] Furthermore, the optical fiber amplifier also has an adjustment button for adjusting the photosensitivity reference value. The adjustment button is located on one of the side walls of the optical fiber amplifier, and the adjustment button and the display screen are both on the same plane of the optical fiber amplifier.

[0016] During the working process, a paper roll without a splice joint is placed in the paper roll joint detection passage between the light projector and the light receiver. The paper roll without a splice joint blocks part of the light projected from the light projector to the light receiver, reducing the amount of light on the light receiver. The light receiver then transmits the information of the reduced light amount to the optical fiber amplifier for amplification. The light sensitivity value amplified by the optical fiber amplifier is displayed on the display screen of the optical fiber amplifier. This displayed light sensitivity value serves as the detection reference light sensitivity value.

[0017] When the baseline light sensitivity value of the unspliced ​​paper reel is obtained, the unspliced ​​paper reel is removed from the paper reel joint detection passage between the light-emitting end of the light-emitting device and the light-receiving end. Then, the paper reel to be inspected is placed in the spliced ​​paper reel detection passage between the light-emitting end of the light-emitting device and the light-receiving end and moved, so that the light-emitting device, the light-receiving device and the optical fiber amplifier can detect the paper reel to be inspected.

[0018] During this detection process, if the sensitivity value displayed on the display screen of the optical fiber amplifier is different from the baseline sensitivity value detected by the paper reel without a spliced ​​joint, there is a joint on the paper reel to be tested; if the sensitivity value displayed on the display screen of the optical fiber amplifier is the same as the baseline sensitivity value detected by the paper reel without a spliced ​​joint, there is no joint on the paper reel to be tested.

[0019] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0020] 1. The utility model sets a paper joint detection passage between the light-emitting end of the light-emitting device and the light-receiving end, and the light-emitting device and the light-receiving end are respectively connected to the optical fiber amplifier, and the optical fiber amplifier is also provided with a display screen for displaying the light sensitivity value; when detecting whether there is a joint on the paper reel on the paper reel turntable, the paper to be detected can be placed in the paper joint detection passage set between the light-emitting end of the light-emitting device and the light-receiving end, and the light-emitting device, the light-receiving end and the optical fiber amplifier cooperate to detect whether there is a joint on the paper reel to be detected. If the optical fiber amplifier If the sensitivity value displayed on the display screen is different from the reference sensitivity value, there is a joint on the paper to be detected; if the sensitivity value displayed on the display screen on the optical fiber amplifier is the same as the reference sensitivity value, there is no joint on the paper to be detected. In this way, not only the original joint on the paper can be detected, but also the original joint on the paper can be detected, which solves the problem that when detecting the paper joints on the paper turntable, the equipment's built-in detection probe is used for detection, which can only accurately detect the spliced ​​joints when the paper is replaced, and the detection accuracy of the original joints on the paper is not enough.

[0021] 2. The utility model connects the second end of the power signal line to the controller that controls the action of the cigarette rejection mechanism. When the photoelectric sensor detects an unqualified splicing joint on a cigarette, the photoelectric sensor will control the controller that controls the action of the cigarette rejection mechanism through the power signal line, thereby rejecting the unqualified cigarettes from the production line and further improving the quality of cigarettes.

[0022] 3. The optical fiber amplifier in the present invention also has an adjustment button for adjusting the photosensitivity reference value, which can ensure that the probe sensitivity in the photoelectric sensor is high. When the reference value changes in actual production, the adjustment button of the photosensitivity reference value can be adjusted to make the photosensitivity reference value meet the actual detection needs, thereby further improving the accuracy of joint detection on the paper reel.

DETAILED DESCRIPTION

[0028] like Figure 1-4 In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Example

[0030] The existing method for detecting joints on coil paper generally uses the detection probe that comes with the equipment for detection. However, since the original joint process is better than the coil paper joint process (the original joint splicing process is better than the coil paper joint splicing process, that is, the original joint connection sealing is good), the detection probe can only accurately detect the coil paper joints spliced ​​when the coil paper is replaced. The detection accuracy of the original joints on the coil paper is not enough, resulting in inaccurate detection results of the spliced ​​joints on the coil paper, which in turn affects the quality of the cigarettes.

[0031] Therefore, the present application proposes a paper roll joint detection device to solve the problem that when detecting the paper roll joints on the paper roll turntable, the detection probe provided by the equipment is used for detection, which can only accurately detect the spliced ​​joints when the paper roll is replaced, and the detection accuracy of the original joints on the paper roll is not enough.

[0032] For details, please refer to Figure 1 The paper roll joint detection device includes a photoelectric sensor 1 and an optical fiber amplifier 5; the photoelectric sensor 1 includes a light projector 2 and a light receiver 3, and a paper roll joint detection passage 4 is provided between the light projector 2 and the light receiver 3; the light projector 2 and the light receiver 3 are respectively connected to the optical fiber amplifier 5, and the optical fiber amplifier 5 has a display screen 6 for displaying the photosensitivity value.

[0033] In actual use, a paper roll without a splice joint is placed in the paper roll joint detection passage 4 between the light projector 2 and the light receiver 3. The paper roll without a splice joint blocks part of the light projected from the light projector 2 to the light receiver 3, and the light intensity of the light receiver 3 is reduced. Then, the light receiver 3 transmits the information of the reduced light intensity to the optical fiber amplifier 5 for amplification. The light sensitivity value amplified by the optical fiber amplifier 5 is displayed on the display screen 6 on the optical fiber amplifier 5. This displayed light sensitivity value serves as the detection reference light sensitivity value.

[0034] When the baseline light sensitivity value of the unspliced ​​paper reel is obtained, the unspliced ​​paper reel is removed from the paper reel joint detection passage 4 between the light-emitting end of the light-emitting device 2 and the receiving end of the light-receiver 3. Then, the paper reel to be inspected is placed in the spliced ​​paper reel detection passage 4 between the light-emitting end of the light-emitting device 2 and the receiving end of the light-receiver 3 and moved, so that the light-emitting device 2, the light-receiver 3 and the optical fiber amplifier 5 can detect the paper reel to be inspected.

[0035] During this detection process, if the sensitivity value displayed on the display screen 6 on the optical fiber amplifier 5 is different from the baseline sensitivity value detected by the paper roll without a spliced ​​joint, then there is a joint on the paper roll to be detected; if the sensitivity value displayed on the display screen 6 on the optical fiber amplifier 5 is the same as the baseline sensitivity value detected by the paper roll without a spliced ​​joint, then there is no joint on the paper roll to be detected.

[0036] See also Figure 2 and Figure 3 In order to facilitate the installation of the light projector 2 and the light receiver 3 on the cigarette making machine, the paper coil joint detection device also includes a connecting plate 11, wherein the side wall of the connecting plate 11 is provided with a through groove 12 for the paper coil to pass through, and the through groove 12 divides the lower half of the connecting plate 11 into a first mounting position 13 and a second mounting position 14. The first mounting position 13 is detachably installed with the light projector 2, and the second mounting position 14 is detachably installed with the light receiver 3.

[0037] In actual use, when installing the light projector 2 and the light receiver 3 on the cigarette making machine, the light projector 2 can be installed at the first mounting position 13 on the connecting plate 11 and the light receiver 3 can be installed at the second mounting position 14 on the connecting plate 11, and then the top of the connecting plate 11 is connected to the side wall of the cigarette making machine through a bolt assembly to complete the process of installing the light projector 2 and the light receiver 3 on the cigarette making machine.

[0038] It should be noted that the light projector 2 and the light receiver 3 are existing technologies and have not been improved or designed, so their structures will not be described in detail.

[0039] See also Figure 1 、 Figure 2 and Figure 3During the paper roll inspection process, to prevent the paper in the paper roll inspection passage 4 from interfering with the connecting plate 11, the paper roll inspection passage 4 and the through slot 12 on the connecting plate 11 for paper rolls to pass through are interconnected, so that the paper roll to be inspected passes through the paper roll inspection passage 4 and the through slot 12 on the connecting plate 11 in sequence.

[0040] In order to prevent the paper from being scratched by the through slot 12 when the paper passes through the through slot 12 , the edge of the through slot 12 through which the splice paper passes is covered with a flexible layer 15 for preventing scratches.

[0041] In actual use, when detecting whether there is a joint in the paper roll, the light projector 2, the light receiver 3 and the optical fiber amplifier 5 are first put into working state, and then the paper roll to be detected is passed through the detection passage 4 and the through slot 12 on the connecting plate 11 for the jointed paper roll to pass through in turn. The light projector 2 and the light receiver 3 located on both sides of the through slot 12 cooperate with the optical fiber amplifier 5 to detect the paper roll to be detected.

[0042] See also Figure 4 In order to facilitate the light projector 2 and the light receiver 3 to transmit signals to the optical fiber amplifier 5, the paper joint detection device also includes an optical fiber 7; specifically, the light projector 2 and the light receiver 3 are connected to the optical fiber amplifier 5 through the optical fiber 7 respectively.

[0043] In actual use, when the light projector 2 and the light receiver 3 transmit signals to the optical fiber amplifier 5, the information received by the light projector 2 and the light receiver 3 can be transmitted to the optical fiber amplifier 5 by means of optical fibers connected to the light projector 2 and the light receiver 3 respectively.

[0044] It should be noted that the optical fiber amplifier 5 is an existing technology and has not been improved or designed, so its structure will not be described in detail.

[0045] See also Figure 4 In order to supply power to the light projector 2, the light receiver 3 and the optical fiber amplifier 5, the paper joint detection device also includes an optical fiber 7 and a power signal line 8; specifically, the first end of the power signal line 8 is connected to the optical fiber amplifier 5, and the second end of the power signal line 8 is respectively connected to the power supply of the cigarette making machine and the controller that controls the action of the cigarette rejection mechanism.

[0046] In actual use, when powering the light projector 2, the light receiver 3 and the optical fiber amplifier 5, the power supply on the cigarette making machine can be introduced into the light projector 2, the light receiver 3 and the optical fiber amplifier 5 with the help of the power signal line 8 to meet the power requirements of the light projector 2, the light receiver 3 and the optical fiber amplifier 5 when in use.

[0047] In addition, if the photoelectric sensor detects an unqualified splicing joint on a cigarette, the photoelectric sensor will control the controller that controls the action of the cigarette removal mechanism through the power signal line 8, and remove the unqualified cigarettes from the production line, further improving the quality of the cigarettes.

[0048] It should be noted that the first end of the power signal line 8 is connected to one end of the connecting plug 9 , and the other end of the connecting plug 9 is plugged into a socket on one side wall of the optical fiber amplifier 5 .

[0049] See also Figure 4 In order to cope with the high sensitivity of the probe in the photoelectric sensor and the change of the reference value in actual production, the optical fiber amplifier 5 is also provided with an adjustment button 10 for adjusting the photosensitivity reference value, wherein the adjustment button 10 is located on one of the side walls of the optical fiber amplifier 5, and the adjustment button 10 and the display screen 6 are both on the same plane of the optical fiber amplifier 5.

[0050] In actual use, if there is a change in the reference value, the sensitivity reference value can be adjusted by adjusting the adjustment button to make the sensitivity reference value meet the actual detection requirements, thereby indirectly improving the accuracy of paper joint detection.
