Technical Field
[0001] This invention relates to an anti-counterfeiting paper and its manufacturing method, specifically to a security thread positioning and dispensing paper, its manufacturing method, and a security thread positioning and dispensing device. Background Technology
[0002] Items such as banknotes, securities, passports, bills, and certificates are all made of anti-counterfeiting paper. Many anti-counterfeiting papers enhance their anti-counterfeiting capabilities by incorporating security threads. Currently, most anti-counterfeiting papers with security threads have a security thread width of less than 5mm, and the text or anti-counterfeiting icons on the security thread are randomly distributed on the anti-counterfeiting paper, resulting in poor anti-counterfeiting capabilities. Summary of the Invention
[0003] To overcome the above-mentioned defects, the present invention provides a security thread positioning and application paper, a manufacturing method thereof, and a security thread positioning and application device. The anti-counterfeiting feature icons on the anti-counterfeiting paper manufactured by this method are positioned and applied to the windowed part of the paper, which improves the recognizability of the anti-counterfeiting paper and thus enhances the anti-counterfeiting characteristics of the paper.
[0004] The technical solution adopted by the present invention to solve its technical problem is: a security thread positioning and paper placement method, comprising a paper sheet and a security thread, wherein the security thread is positioned and placed inside the paper sheet, and at least one window is formed at intervals on one side of the paper sheet, and at least one icon with anti-counterfeiting features is provided at intervals on the security thread, wherein the icon with anti-counterfeiting features on the security thread is directly opposite to the window on the paper sheet, and the icon with anti-counterfeiting features is fully exposed on the surface of the paper sheet through the window.
[0005] As a further improvement of the present invention, the width of the safety line is 5mm-10mm.
[0006] A method for manufacturing paper with a security line positioning and dispensing capability, comprising the following steps:
[0007] Step 1: Design the security thread according to the number and location of the windows on the ticket. The number of anti-counterfeiting icons on the security thread should be the same as the number of windows on the ticket, and the spacing between the anti-counterfeiting icons on the security thread should be the same as the spacing between the windows on the ticket.
[0008] Step Two: Fabricate the safety line according to the design plan;
[0009] Step 3: Use a cylinder paper machine to make wet paper sheets with windows. During the wet paper sheet making process, use a security thread positioning and placement device to place the security thread on the surface of the wet paper sheet. Adjust the security thread placement device to make the icons of the anti-counterfeiting features on the security thread aligned with the windows on the wet paper sheet. Finally, the paper peeling roller peels off the wet paper sheet with the security thread and conveys it forward.
[0010] As a further improvement of the present invention, when designing the security line in step one, the position of the first window on the ticket is consistent with the position of the first icon with anti-counterfeiting features along the release direction on the security line, and the spacing between the last window of the previous large sheet of paper and the first window of the next large sheet of paper within one circumference of the circular net cage is consistent with the spacing between the icon with anti-counterfeiting features on the security line.
[0011] As a further improvement of the present invention, when designing the security line in step one, the positional accuracy of the icon with anti-counterfeiting features on the security line is designed according to the stretching ratio of the security line.
[0012] A security thread positioning and deployment device includes a frame, a security thread unwinding device, a guide wheel, an anti-counterfeiting feature detection sensor, a cylinder wire cage position detection sensor, a security thread tension adjustment mechanism, and a control system. The security thread unwinding device, the anti-counterfeiting feature detection sensor, and the cylinder wire cage position detection sensor are respectively fixedly installed on the frame. The guide wheel is rotatably installed on the frame. The security thread reel is detachably fixedly installed on the security thread unwinding device. The security thread unwinding device can rotate and unwind the security thread reel. One end of the security thread is led out from the security thread reel, passes through the security thread tension adjustment mechanism and at least one guide wheel, and then combines with the wet paper sheet on the surface of the cylinder wire cage of the cylinder paper machine. The security thread tension adjustment mechanism can adjust the tension of the security thread. The anti-counterfeiting feature detection sensor can detect the position of the anti-counterfeiting feature icon on the security thread. The cylinder wire cage position detection sensor can detect the window position on the wet paper sheet on the cylinder wire surface. The anti-counterfeiting feature detection sensor and the cylinder wire cage position detection sensor are electrically connected and communicate with the control system. The control system controls the operation of the security thread tension adjustment mechanism.
[0013] As a further improvement of the present invention, the safety line tension adjustment mechanism includes a servo motor and an adjustment wheel. The adjustment wheel is rotatably mounted on the frame. The servo motor drives the adjustment wheel to rotate, and the safety line tightly wraps around the outer surface of the sleeve wheel.
[0014] As a further improvement of the present invention, the diameter of the adjusting wheel is 120mm, and the angle of the safety line on the outer surface of the circumference of the adjusting wheel is greater than 240°.

[0016] As a further improvement of the present invention, both the anti-counterfeiting feature detection sensor and the circular mesh position detection sensor are photoelectric sensors.
[0017] The beneficial effects of this invention are: This invention uses a wide security thread with a width of 5mm-10mm, and sets an icon with anti-counterfeiting features at a fixed position on the security thread. The icon with anti-counterfeiting features at a fixed position on the security thread is positioned and applied to the windowed part of the paper, which greatly improves the recognizability of the anti-counterfeiting paper, thereby improving the anti-counterfeiting characteristics of the paper.

[0026] Example: A security thread positioning and paper placement method includes a paper sheet 1 and a security thread 2. The security thread 2 is positioned and placed inside the paper sheet 1. At least one window 3 is formed at intervals on one side of the paper sheet 1. At least one icon 4 with anti-counterfeiting features is provided at intervals on the security thread 2. The icon 4 with anti-counterfeiting features on the security thread 2 is directly opposite to the window 3 on the paper sheet 1, and the icon 4 with anti-counterfeiting features is fully exposed on the surface of the paper sheet 1 through the window 3.
[0027] Page 1, based on the ticket design, has one or more windows 3 on each ticket. The security thread 2 also has one or more anti-counterfeiting icons 4. The spacing between each anti-counterfeiting icon 4 on the security thread 2 matches the spacing between the windows 3 on the paper. The anti-counterfeiting icons 4 on the security thread 2 are positioned and placed on the windows 3 on the paper, so that each window 3 on page 1 corresponds to one anti-counterfeiting icon 4. The anti-counterfeiting icons 4 are fully exposed on the paper surface at each window 3 on page 1 (e.g., ...). Figure 1 , Figure 2 (The window 3 area), the remaining security thread 2 is buried inside the paper 1 (such as...) Figure 1 , Figure 2The security thread is fully embedded in the area. This type of anti-counterfeiting paper has high recognition and effectively improves the anti-counterfeiting characteristics of the paper.
[0028] The security line 2 is 5mm-10mm wide, which makes the anti-counterfeiting feature icon 4 on the security line 2 at the window 3 on the paper 1 clearly visible to the naked eye.
[0029] A method for manufacturing paper with a security line positioning and dispensing capability, comprising the following steps:
[0030] Step 1: Design the security thread 2 according to the number and location of the windows 3 on the ticket. The number of anti-counterfeiting icons 4 on the security thread 2 is the same as the number of windows 3 on the ticket. The spacing between the anti-counterfeiting icons 4 on the security thread 2 is the same as the spacing between the windows 3 on the ticket. Ensure that the vertical distance between the anti-counterfeiting features is the same as the vertical distance between the windows 3 on the ticket.
[0031] Step 2: Fabricate safety line 2 according to the design plan;
[0032] Step 3: The wet paper sheet 1 with the window 3 is made using a cylinder paper machine. During the wet paper sheet 1 making process, the security thread 2 positioning and placement device is used to place the security thread 2 on the surface of the wet paper sheet 1. By adjusting the security thread 2 placement device, the icon 4 of the anti-counterfeiting feature on the security thread 2 is aligned with the window 3 on the wet paper sheet 1. Finally, the paper peeling roller 12 peels off the wet paper sheet 1 with the security thread 2 and conveys it forward.
[0033] When designing the security thread 2 in step one, the position of the first window 3 on the ticket surface is consistent with the position of the first anti-counterfeiting icon 4 on the security thread 2 along the deployment direction. Furthermore, the spacing between the last window 3 on the previous large sheet of paper and the first window 3 on the next large sheet within a circumference of the circular mesh cage 9 and the anti-counterfeiting icon 4 on the security thread 2 is consistent. This ensures that when the circular mesh cage 9 is processing the wet paper sheet 1, the window 3 on it is always consistent with the position of the anti-counterfeiting icon 4 on the security thread 2. Moreover, when the security thread 2 is deployed, as long as the end of the security thread 2 is aligned with the end of the wet paper sheet 1, the anti-counterfeiting icon 4 and the window 3 will correspond.
[0034] In step one, when designing the security thread 2, the positional accuracy of the anti-counterfeiting icon 4 on the security thread 2 is designed based on the stretching ratio of the security thread 2. The influence of the stretching ratio of the security thread 2 on the positioning accuracy is considered when designing the position of the anti-counterfeiting icon 4 on the security thread 2, ensuring that when the security thread 2 is deployed, the anti-counterfeiting icon 4 corresponds to the position of the window 3 on the wet paper sheet 1.
[0035] A method for manufacturing paper with a security thread positioning and dispensing device includes a frame, a security thread unwinding device 5, a guide wheel 6, an anti-counterfeiting feature detection sensor 7, a cylinder wire cage 9 position detection sensor 8, a security thread 2 tension adjustment mechanism, and a control system. The security thread unwinding device 5, the anti-counterfeiting feature detection sensor 7, and the cylinder wire cage position detection sensor are respectively fixedly mounted on the frame. The guide wheel 6 is rotatably mounted on the frame. The security thread 2 reel is detachably fixedly mounted on the security thread unwinding device 5. The security thread unwinding device 5 can rotate and unwind the security thread 2 reel. One end of the wire extends from the material tray of the security line 2, passes through the tension adjustment mechanism of the security line 2 and at least one guide wheel 6, and then combines with the wet paper sheet 1 on the surface of the cylinder wire cage 9 of the cylinder paper machine. The tension adjustment mechanism of the security line 2 can adjust the tension of the security line 2. The anti-counterfeiting feature detection sensor 7 can detect the position of the icon 4 with anti-counterfeiting features on the security line 2. The position detection sensor of the cylinder wire cage 9 can detect the position of the window 3 on the wet paper sheet 1 on the surface of the cylinder wire. The anti-counterfeiting feature detection sensor 7 and the position detection sensor of the cylinder wire cage 9 are electrically connected and communicate with the control system. The control system controls the operation of the tension adjustment mechanism of the security line 2. Sensors are used to detect the positions of the anti-counterfeiting icon 4 on the security thread 2 and the paper window 3 on the cylindrical wire cage 9. The positional difference between the anti-counterfeiting icon 4 and the paper window 3 on the cylindrical wire cage 9 at the time of connection is calculated based on the sensor detection results. The tension adjustment mechanism of the security thread 2 is controlled by the detected positional difference between the anti-counterfeiting icon 4 and the paper window 3 on the cylindrical wire cage 9 to achieve longitudinal adjustment of the anti-counterfeiting icon 4 on the security thread 2. This ensures that the anti-counterfeiting icon 4 on the security thread 2 is placed facing the window 3 on the wet paper sheet 1, avoiding misalignment of the anti-counterfeiting icon 4 and the window 3 on the wet paper sheet 1 due to stretching caused by tension during the placement of the security thread 2.
[0036] The tension adjustment mechanism of the safety line 2 includes a servo motor and an adjusting wheel 10. The adjusting wheel 10 is rotatably mounted on the frame. The servo motor drives the adjusting wheel 10 to rotate, and the safety line 2 tightly wraps around the outer circumference of the sleeve wheel. The servo motor controls the rotational speed of the adjusting wheel 10, and the tension of the safety line 2 is adjusted by the friction between the safety line 2 and the adjusting wheel 10. Alternatively, the tension of the safety line 2 can be changed by adjusting the position of the adjusting wheel 10 left or right. This is an equivalent replacement structure that is easily conceived by those skilled in the art based on this patent and falls within the scope of protection of this patent.
[0037] The diameter of the adjusting wheel 10 is 120mm, and the angle of the safety line 2 on the outer surface of the circumference of the adjusting wheel 10 is greater than 240°, which ensures that the adjusting wheel 10 has sufficient friction with the safety line 2.
[0038] The safety line unwinding device 5 is a constant tension unwinding device, and the unwinding tension of the constant tension unwinding device is 80cN-120cN.
[0039] Both the anti-counterfeiting feature detection sensor 7 and the circular mesh position detection sensor are photoelectric sensors. In addition to photoelectric sensors, other sensors can also be used, such as imaging devices, as long as they can detect the position of the icon 4 of the anti-counterfeiting feature and the position of the window 3 on the wet paper 1.
