Description

Technical Field

[0001] This application relates to the field of cigarette packaging technology, specifically to a GDX2 unit paper cutting color mark position detection device. Background Technology

[0002] During the operation of the GDX2 unit, paper jams undergo mechanical phase orientation cutting within the inner frame paper assembly. Traditional detection methods use photoelectric reflection.

[0003] Chinese utility model patent CN206871421U discloses a novel detector for the frame paper conveying process of a GDX2 packaging machine. This detector achieves its detection function by positioning the beam of a photoelectric detector 1 mm above the mold box at station 2 of wheel 4. When the inner frame paper is in place, the beam is reflected back to the photoelectric detector by a reflector, maintaining a 24V voltage at the signal output terminal, and the indicator light illuminates to indicate normal operation. If any end of the inner frame paper is 1-2 mm higher than the mold box, it will affect or block the beam from being reflected back to the photoelectric detector, causing the signal to flip, triggering a stop alarm and displaying a red alarm message "Inner frame paper platform open." The machine is reset and restarted after the operator resolves the problem.

[0004] However, while this detection method can effectively detect paper frames and objects protruding from the die box and promptly stop the machine with an alarm, it can only detect whether a paper jam has passed the detection point. It cannot guarantee the accurate positioning of the paper jam and still has the problem of not being able to determine if there is a paper jam in the die box. With the increasing diversity of products and the increasing special requirements, such as printing special patterns like QR codes on paper, higher precision is required for the cutting position of the paper. Therefore, a technology is needed that can ensure the validity of the paper pattern, prevent increased waste smoke caused by the lag in the cutting system, and improve quality and production efficiency.

[0005] To address the aforementioned issues, it is necessary to develop a paper jam and color mark position detection device for the GDX2 unit. This device can achieve precise and stable paper feeding, and will automatically reject the defective inner frame paper when compensation fails, thereby maximizing product quality assurance. Utility Model Content

The color mark sensor identifies the position of the line on the paper jam to determine its color, detects the paper jam's location, and transmits the detection results to the industrial control computer. This enables precise monitoring of the paper jam cutting position and pattern integrity, improving production efficiency and product quality, and reducing the scrap rate.

[0007] Specifically, this utility model provides a GDX2 unit paper jam cutting color mark position detection device, characterized in that it includes: a bottom fixing bracket for the color mark sensor fiber optic cable, a fiber optic distance adjustment bracket, and a color mark sensor fixing bracket; the bottom fixing bracket for the fiber optic cable is installed below the fifth round paper jam conveying mold box of X2 and is fixedly connected to the original exhaust hole of the machine for fixing the color mark sensor; the fiber optic distance adjustment bracket is fixedly installed on the bottom fixing bracket for the fiber optic cable, and the position of the color mark sensor is adjusted by the fiber optic distance adjustment bracket; the color mark sensor is installed on the fixing bracket for the color mark sensor, and determines the color of the line by identifying the position on the paper jam to determine whether the paper jam is being cut at the specified position to ensure normal paper jam cutting; the color mark sensor is connected to the industrial control computer and transmits the detection results to the industrial control computer.

[0008] Furthermore, the fiber optic bottom fixing bracket is a fixed horizontal plate, which has a circular opening, an elliptical opening, and a first strip-shaped opening; the circular opening is fixedly connected to the machine's original exhaust hole by bolts, and the fiber optic bottom fixing bracket is fixedly installed below the X2 fifth round paper conveying mold box; the color mark sensor passes through the elliptical opening and is connected to the fiber optic distance adjustment bracket; the fiber optic distance adjustment bracket is fixedly installed on the fiber optic bottom fixing bracket through the first strip-shaped opening.

[0009] Furthermore, the color mark sensor includes: an optical fiber, a signal line, and a signal processing circuit; the optical fiber passes through an elliptical opening and is connected to the optical fiber distance adjustment bracket by bolts, for capturing color information on the card and transmitting it to the signal processing circuit via the signal line.

[0010] Furthermore, the fiber optic distance adjustment bracket is configured as a "C" shape, and the fiber optic distance adjustment bracket has a second strip-shaped opening and a third strip-shaped opening; the second strip-shaped opening is connected to the first strip-shaped opening on the fiber optic distance adjustment bracket by bolts; the third strip-shaped opening is connected to the optical fiber by bolts.

[0011] Furthermore, the color mark sensor mounting bracket is configured as an "N" shape, and the color mark sensor mounting bracket has a color mark sensor strip hole and a color mark sensor round hole; the color mark sensor strip hole is used to fix the mounting bracket of the color mark sensor to the machine below the bottom mounting bracket of the optical fiber by bolts, and is used to fix and support the signal processing circuit; the color mark sensor round hole is used to install the signal processing circuit.

[0012] Furthermore, the fiber distance adjustment bracket moves within the first strip-shaped opening on the bottom fixing bracket of the fiber.

[0013] Furthermore, the third strip-shaped opening on the fiber optic distance adjustment bracket is used to fix the position of the fiber optic cable when the bolt is tightened; the position of the fiber optic cable is adjusted when the bolt is loosened.

[0014] Furthermore, the industrial control computer has a built-in audible and visual alarm. When the color mark sensor detects a defective paper jam, the audible and visual alarm will sound.

[0015] Working principle: When the GDX2 unit paper jam cutting color mark position detection device is working, firstly, the bottom fixing bracket 2 of the optical fiber is installed below the fifth paper jam conveying mold box of X2, and fixedly connected to the original exhaust hole 3 of the machine to ensure the stability of the entire detection device; the optical fiber distance adjustment bracket 4 is installed on the bottom fixing bracket 2 of the optical fiber; then, the fixing bracket 5 of the color mark sensor is fixedly installed on the machine below the bottom fixing bracket 2 of the optical fiber, and the signal processing circuit 13 of the color mark sensor 1 is installed on the fixing bracket 5 of the color mark sensor. The optical fiber 11 of the color mark sensor 1 passes through the elliptical opening 22 and is connected to the optical fiber distance adjustment bracket 4. The position of the optical fiber 11 is adjusted by the cooperation of the optical fiber distance adjustment bracket 4 and the optical fiber bottom fixing bracket 2 to adapt to the detection requirements of different paper jams. When adjusting the position of the optical fiber 11, there are two methods: First, loosen the connecting bolt between the optical fiber 11 and the third strip opening 42, move the optical fiber 11 within the range of the third strip opening 42, and adjust the position of the optical fiber 11. Second, loosen the connecting bolt between the first strip opening 23 and the second strip opening 41, move the optical fiber distance adjustment bracket 4, and adjust the position of the optical fiber 11. After the position is adjusted, tighten the bolts to fix the adjusted position of the optical fiber 11. When the conveyor box rotates to the position of the fifth paper conveyor box of X2, the optical fiber 11 captures the color information on the paper and transmits the data to the signal processing circuit 13 through the signal line 12. The signal processing circuit 13 determines the color of the line based on the position on the paper and determines whether the cutting and folding of the paper is qualified. The detection signal is then sent to the industrial control computer. When a paper that is misaligned or skewed is detected, the industrial control computer has a built-in audible and visual alarm. When the color mark sensor 1 detects a paper that is not qualified, the audible and visual alarm is activated. At the same time, the industrial control computer controls the rejection station to reject the unqualified products.

Detailed Implementation

[0033] The technical solution will now be described in detail with reference to the accompanying drawings of the embodiments of this utility model.

[0034] Example 1

[0035] like Figure 7 As shown, a GDX2 paperboard cutting and color mark position detection device includes: a color mark sensor 1, an optical fiber 11, a signal line 12, a signal processing circuit 13, an optical fiber bottom fixing bracket 2, a circular opening 21, an elliptical opening 22, a first strip opening 23, a fixing plate 24, an exhaust hole 3, an optical fiber distance adjustment bracket 4, a second strip opening 41, a third strip opening 42, a color mark sensor fixing bracket 5, a color mark sensor strip hole 51, a color mark sensor circular hole 52, an X2 fifth-round paperboard conveying mold box 6, a GDX2 white paperboard fixed-length cutting device 7, paperboard 8, and paperboard color mark dots 9.

[0036] like Figure 2 , 6As shown, the fiber optic bottom fixing bracket 2 is a fixed horizontal plate 24, with a circular opening 21, an elliptical opening 22 and a first strip opening 23 set on the fixed horizontal plate 24; the circular opening 21 is fixedly connected to the machine's original exhaust hole 3 by bolts, and the fiber optic bottom fixing bracket 2 is fixedly installed below the X2 fifth round paper conveying mold box.

[0037] like Figure 7 As shown, the fiber optic distance adjustment bracket 4 is C-shaped, with a second strip opening 41 and a third strip opening 42 on it. The second strip opening 41 and the first strip opening 23 on the fiber optic distance adjustment bracket 4 are bolted together to mount the fiber optic distance adjustment bracket 4 onto the bottom fixing bracket 2 of the fiber optic cable. The third strip opening 42 is bolted to the fiber optic cable 11. The position of the color mark sensor 1 is adjusted using the fiber optic distance adjustment bracket 4.

[0038] like Figure 6 As shown, the fiber optic distance adjustment bracket 4 moves within the first strip-shaped opening 23 on the fiber optic bottom fixing bracket 2. The third strip-shaped opening 42 on the fiber optic distance adjustment bracket 4 is used to fix the position of the fiber optic 11 when the bolt is tightened; the position of the fiber optic 11 is adjusted when the bolt is loosened.

[0039] like Figure 6 As shown, the color mark sensor mounting bracket 5 is configured as an "N" shape, and the color mark sensor mounting bracket has a color mark sensor strip hole 51 and a color mark sensor round hole 52. The color mark sensor strip hole 51 is used to fix the color mark sensor mounting bracket 5 to the machine below the fiber optic bottom mounting bracket 2 by bolts, and is used to fix and support the signal processing circuit 13. The color mark sensor round hole 52 is used to install the signal processing circuit 13.

[0040] like Figure 1-4 As shown, the optical fiber 11 of the color mark sensor 1 passes through the elliptical opening 22 and is connected to the optical fiber distance adjustment bracket 4 by bolts. It is used to capture color information on the card and transmit it to the signal processing circuit 13 through the signal line 12.

[0041] Color mark sensor 1 uses an LR-WF10(C) fiber optic white spot photoelectric sensor, which connects to the industrial control computer and transmits the detection results to the computer. Its main function is to identify the color of the position judgment line on the paper jam to determine whether the paper jam is at the specified position for cutting, thus ensuring normal paper cutting. When color mark sensor 1 outputs a signal to the industrial control computer, if the output signal indicates "position judgment line present," the industrial control computer operates normally. If the output signal indicates "no position judgment line present," the industrial control computer sends a signal to the downstream rejection station to reject the paper at that rejection point and displays a "fifth round no pull piece" alarm fault on the upper level. When the number of rejections reaches three or more consecutively, the industrial control computer's built-in audible and visual alarm sounds.

[0042] The GDX2 packaging unit has undergone program improvements, with a setting to stop the machine after rejecting more than 3 packages. This reminds staff to check the equipment's operation and prevent issues such as paper jams, changes in patterns, or failure to adjust the cutting position, which could lead to excessive waste smoke.

[0043] like Figure 4 As shown, in use, firstly, install the fiber optic bottom fixing bracket 2 below the X2 fifth-round paper conveying mold box 6, and fix it to the machine's original exhaust hole 3 to ensure the stability of the entire detection device; install the fiber optic distance adjustment bracket 4 on the fiber optic bottom fixing bracket 2; then fix the color mark sensor fixing bracket 5 on the machine below the fiber optic bottom fixing bracket 2, install the signal processing circuit 13 of the color mark sensor 1 on the color mark sensor fixing bracket 5, and connect the fiber optic distance adjustment bracket 4 through the elliptical opening 22; through the fiber optic distance adjustment bracket... The frame 4 and the fiber optic bottom fixing bracket 2 work together to adjust the position of the fiber optic 11 to adapt to the detection requirements of different paper cards 8. When adjusting the position of the fiber optic 11, there are two methods: First, loosen the connecting bolt between the fiber optic 11 and the third strip opening 42, move the fiber optic 11 within the range of the third strip opening 42, and adjust the position of the fiber optic 11. Second, loosen the connecting bolt between the first strip opening 23 and the second strip opening 41, move the fiber optic distance adjusting bracket 4, and adjust the position of the fiber optic 11. After the position is adjusted, tighten the bolts to fix the adjusted position of the fiber optic 11. When the conveyor box rotates to the position of the fifth paper conveyor box 6 of X2, the optical fiber 11 captures the color information of the paper color mark 9 on the paper 8 and transmits the data to the signal processing circuit 13 through the signal line 12. The signal processing circuit 13 determines whether the cutting and folding of the paper 8 is qualified based on the color of the paper color mark 9 on the paper 8 and sends the detection signal to the industrial control computer. When a paper 8 that is displaced or skewed is detected, the industrial control computer has a built-in audible and visual alarm. When the color mark sensor 1 detects a paper 8 that is not qualified, the audible and visual alarm is activated. At the same time, the industrial control computer controls the rejection station to trigger the rejection mechanism by not recognizing a specific color, and rejects the unqualified products. If more than 3 packages are rejected, the machine is stopped to remind the staff to check the operation of the GDX2 packaging machine.
