Description

Technical Field

[0001] The present invention relates to the field of paper slitting, and particularly to an active deviation rectifying slitter. Background Art

[0002] When a slitter cuts a coiled material with a pattern, a slight deviation generated during the conveying process of the coiled material will cause a distance difference between the cutter head and the preset cutting marking line. This deviation will significantly reduce the slitting accuracy. Especially in scenarios with high-precision pattern alignment requirements, a slight displacement can result in unqualified finished product quality. To solve this problem, there is an urgent need to design a slitting system integrated with an active deviation rectifying function, which is a slitter that can monitor the displacement amount of the paper in real time and dynamically adjust the position of the cutter head. Summary of the Invention

[0003] The purpose of the present invention is to provide an active deviation rectifying slitter to solve the above technical problems.

The coiled material enters and exits the frame, and the camera assembly photographs the marking points on the surface of the coiled material. It also includes a first paper pressing assembly that drives the coiled material to move linearly within the frame. A first deviation rectifying assembly is also provided in the frame. The first deviation rectifying assembly is equipped with a movable cutting trolley. The cutting trolley can cut the coiled material in a stationary state during movement. The first deviation rectifying assembly is axially connected to the frame. When the coiled material has an angular deviation in the entering and exiting direction, the first deviation rectifying assembly deflects relative to the frame to correct the cutting position of the cutting trolley.

[0006] The structure adjacent to the first deviation rectifying assembly is a second deviation rectifying assembly. The second deviation rectifying assembly includes a driving structure and a tool fixing part. The tool fixing part fixes a plurality of slitting knives. Among them, the slitting knives cut the coiled material before the cutting trolley. The slitting knives can cut the coiled material in a moving state. The driving structure drives the tool fixing part to move linearly in the direction perpendicular to the entering and exiting direction of the coiled material. When the coiled material has an offset relative to the entering and exiting direction, the slitting knives move horizontally synchronously with the paper to correct the cutting position of the slitting knives.

[0010] Preferably, there is a rotating shaft at the bottom of the operating table, and the structure that cooperates with the rotating shaft is an axle seat installed in the frame. The relative position of the rotating shaft is an adapter, which is connected to the operating table shaft. There is also a driving part, which drives the adapter to move in the direction of the coil in and out, so that the operating table can be deflected at an angle with the rotating shaft as the fulcrum.

[0011] Preferably, the tool fixing part in the second correcting assembly is a tool rod, and the structure for driving the tool fixing part in the second correcting assembly includes a stand installed on the outside of the frame, the bottom of the stand is a second motor, the top of the second motor is a screw structure, the second motor is the power source of the screw structure, and also includes a tool rod seat connected to the screw structure, and when the second motor drives the screw structure to move, the tool rod seat drives the tool rod to move in a direction perpendicular to the direction of the coil entering and exiting.

[0013] Preferably, the camera assembly includes two independent camera carriages, wherein the camera carriage can move in a direction perpendicular to the direction of the coil in and out, and the camera carriage can also capture continuous detection points on one side of the coil.

[0014] Preferably, when the two camera carriages successively detect detection points in corresponding areas, the first deviation-correcting component performs an angular deflection relative to the frame.

[0030] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the understanding of the disclosure of the present invention is more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0032] The specific embodiments of the present invention will be described below with reference to the drawings.

[0033] Embodiment 1

[0034] In this embodiment, an active deviation rectifying slitter is proposed. Please refer to Figures 1-9 , the multi-target active deviation rectifying slitter includes a frame 2, as Figure 2As shown, the frame 2 is a frame structure, and its main structure is the base 201. On both sides of the base 201 are the first baffle 202 and the second baffle 203 (on one side of the second baffle 203 is the gas distribution system 11, and the gas distribution system 11 supplies gas to all pneumatic structures), and there is also a first cross bar 204 whose ends are respectively connected to the first baffle 202 and the second baffle 203. Please refer to Figure 1 The frame 2 has a covering member, and the covering member is the machine cover 1. Specifically, the machine cover 1 includes the first cover 101 covering the first baffle 202, the third cover 103 covering the second baffle 203, and the second cover 102 covering the first cross bar 204. The second cover 102 has an observation window 104, and the first cover 101 also houses a touch screen 105.

[0035] Please refer to Figure 1 and Figure 2 and take Figure 9 as a reference. The slitter proposed in this embodiment is used to slit a coil. As Figure 9 shown, the coil enters and exits from the frame 2. Please refer to Figures 1-3 Inside the frame 2, a camera assembly 7, a second deviation rectifying assembly 6, a first paper pressing assembly, and a first deviation rectifying assembly 4 are sequentially arranged in the direction of the coil entering and exiting.

[0036] Please refer to Figure 8 The main structure of the camera assembly 7 is two camera trolleys. The camera trolleys are responsible for photographing continuous detection points on the surface of the coil. It should be noted that there are detection points on both sides of the coil, and the detection points on both sides are directly opposite.

[0037] Please continue to refer to Figure 8 The two camera trolleys are respectively the first camera trolley 705 and the second camera trolley 709, and the two camera trolleys can move in the direction perpendicular to the direction of the coil entering and exiting. Please refer to again Figure 8, as the support part of the two camera trolleys, the fourth crossbar 701 is of a hollow structure, and its two sides are respectively fixed to the first baffle 202 and the second baffle 203. Each camera trolley has a support. Specifically, the support for fixing the first camera trolley 705 is the first camera trolley support 704, and the support for fixing the second camera trolley 709 is the second camera trolley support 708. The above trolley supports are installed on the fourth crossbar 701 through clamps. Further, each trolley support has a set of drive structures. Among them, the structure for driving the first camera trolley support 704 is the second synchronous belt system 703 sleeved on the fourth crossbar 701, and the third motor 702 installed outside the first baffle 202 and drivingly connected to the second synchronous belt system 703. When the third motor 702 drives the second synchronous belt system 703 to operate, the first camera trolley support 704 can move relative to the fourth crossbar 701. As above, the structure for driving the second camera trolley support 708 is the third synchronous belt system 707 and the fourth motor 706 installed outside the first baffle 202. The above second camera trolley support 708 is connected to the third synchronous belt system 707. After connection, when the fourth motor 706 drives the third synchronous belt system 707 to operate, the second camera trolley support 708 can move relative to the fourth crossbar 701.

[0038] Please refer to Figure 7 , the second deviation rectifying component 6 includes a drive structure and a tool fixing part. The tool fixing part is used to fix two slitting knives 12, and the slitting knives 12 can cut the coil in a moving state. The above drive structure can drive the tool fixing part to move in the direction perpendicular to the direction of the coil in and out. The function of the second deviation rectifying component 6 is that when the coil photographed by the camera component 7 has a lateral deviation relative to the in and out direction, the slitting knives 12 can follow the paper and perform synchronous lateral movement to correct the cutting position of the slitting knives 12.

[0039] Please continue to refer to Figure 7 , the tool fixing part in the second deviation rectifying component 6 is a tool rod 605. One end of the tool rod 605 is movably installed on the second baffle 203. The structure for driving the tool rod 605 in the second deviation rectifying component 6 includes a bench 601 installed outside the frame 2. Specifically, the bench 601 is installed outside the first baffle 202. There is a second motor 602 at the bottom of the bench 601, and a screw rod structure 603 is at the top of the second motor 602. The second motor 602 is drivingly connected to the screw rod structure 603 through a belt. The object driven by the screw rod structure 603 is a tool rod seat 604. The other end of the above tool rod 605 is fixed to the tool rod seat 604. When the second motor 602 drives the screw rod structure 603, the tool rod seat 604 can make the tool rod 605 move in the direction perpendicular to the direction of the coil in and out.

[0040] Please refer to Figure 4 and Figure 6The first paper pressing assembly is composed of an upper paper pressing structure 5 and a lower paper pressing structure 8. The upper paper pressing structure 5 is above the roll material, and the lower paper pressing structure 8 is below the roll material. Both the upper paper pressing structure 5 and the lower paper pressing structure 8 can roll in contact with the roll material. Unlike the lower paper pressing structure 8, the upper paper pressing structure 5 can move in the height direction according to the thickness of the roll material, thereby clamping the roll material between the upper paper pressing structure 5 and the lower paper pressing structure 8 for stable movement.

[0041] See also Figure 6 The upper paper pressing structure 5 includes a third crossbar limiting portion 501 respectively mounted on the first baffle 202 and the second baffle 203, and also includes a third crossbar 502. Both ends of the third crossbar 502 are constrained by the third crossbar limiting portion 501, and the constrained third crossbar 502 is limited to move in the height direction. Please continue to refer to Figure 6 On both sides of the third cross bar 502 are first cylinders 503 installed on the first baffle 202 and the second baffle 203. The first cylinder 503 is connected to the third cross bar 502. Accordingly, when the two first cylinders 503 are started and stopped synchronously, the third cross bar 502 can be driven to move in the height direction. The upper paper pressing structure 5 also includes an upper glue wheel pressure rod 504 installed at the bottom of the third cross bar 502 for rolling contact with the web.

[0042] See also Figure 4 , opposite to the upper rubber wheel pressure rod 504 is the lower paper pressing structure 8, the lower paper pressing structure 8 includes a workbench 801 installed between the first baffle 202 and the second baffle 203, the workbench 801 has a lower rubber wheel pressure rod 802 inside, and a fifth motor 803 installed on the outside of the first baffle 202 and transmission connected to the lower rubber wheel pressure rod 802. Further explanation, the upper rubber wheel pressure rod 504 is directly opposite to the lower rubber wheel pressure rod 802, wherein the upper rubber wheel pressure rod 504 can move relative to the lower rubber wheel pressure rod 802, adapting to the thickness of the web during movement, and clamping the web between the two.

[0043] See also Figure 5The first deflection-correcting assembly 4 is equipped with a movable cutting trolley 3, which can cut stationary coils while moving. The first deflection-correcting assembly 4 is axially connected to the frame 2. In this embodiment, when the coil photographed by the camera assembly 7 is angularly offset relative to the in-and-out direction, the first deflection-correcting assembly 4 is deflected relative to the frame 2 to correct the cutting position of the cutting trolley 3. The first deflection-correcting assembly 4 includes an operating table 401 installed in the frame 2, through which the coil enters and exits. The operating table 401 is equipped with a second crossbar 402, which has a track 406 for slidingly cooperating with the cutting trolley 3. The first deflection-correcting assembly 4 also includes a first drive motor 405 installed at the side of the operating table 401, and a first synchronous belt system 407 connected to the cutting trolley 3. The first drive motor 405 is in transmission connection with the first synchronous belt system 407, thereby driving the cutting trolley 3 to move linearly along the track 406.

[0044] Please continue reading Figure 5 The bottom of the operating table 401 has a rotating shaft 408, and the structure that cooperates with the rotating shaft 408 is the shaft seat 10 installed in the frame 2. The relative position of the rotating shaft 408 is the adapter 404, which is connected to the operating table 401 axis. There is also a driving unit 403, which is installed on the Figure 2 The extension frame 205 shown further illustrates that the driving portion 403 is consistent with the driving structure for driving the knife rod 605 to move in the second correction component 6, specifically, it includes a motor, a screw and a slide, wherein the motor is connected to the screw through a belt, the structure driven by the screw is a slide, and the slide is connected to the above-mentioned adapter 404. Based on the above-mentioned setting, when the driving portion 403 drives the adapter 404 to move in the direction of the coil in and out, the operating table 401 can be angularly deflected relative to the frame 2 with the rotating shaft 408 as the fulcrum.

[0045] Please refer again Figure 5 A second paper pressing assembly 9 is also provided within the first deflection-correcting assembly 4. Unlike the first paper pressing assembly, the second paper pressing assembly 9 is located within the operating table 401. Its function is to cover and press the web, facilitating the cutting carriage 3 to cut the web within its area (the cutting carriage 3 uses a disc-shaped cutting blade that is mounted in a rolling manner within the cutting carriage 3. If the web is not pressed firmly, the cutting carriage 3 may cut the web off-center). Please refer to Figure 5 There are two second cylinders 901 under the second cross bar 402, and under the second cylinder 901 is a paper pressing board 902. The two second cylinders 901 are connected to the paper pressing board 902, and the paper pressing board 902 can cover the roll material within the stroke range of the two second cylinders 901.

[0046] See also Figure 10, the detection point on the coil is the standard line. During the continuous feeding of the coil, S is the defined fixed camera mark point width. The first camera trolley 705 and the second camera trolley 709 will automatically run to find the standard edge line. If the first camera trolley 705 runs S1 to reach the standard edge line, and the second camera trolley 709 runs S2 to reach the standard edge line, then the distance between the two standard edges is S-(S1+S2); during the continuous feeding of the coil, if the first camera trolley 705 and the second camera trolley 709 detect the standard line at the same time, the left and right feeding of the coil will be synchronized; if If the first camera trolley 705 first detects the standard line, the left side of the coil will be ahead in feeding and the right side will be behind, and the system will automatically calculate the deviation value S3 in the direction of "+"; if the second camera trolley 709 first detects the standard line, the right side of the coil will be ahead in feeding and the left side will be behind, and the system will automatically calculate the deviation value S3 in the direction of "-"; based on the above-mentioned measured data, the cardboard deflection angle can be calculated: tgω=S3 / (S-(S1+S2)), and the deflection angle ω obtained by this algorithm is further applied to the rotation angle of the second correcting component 4.

[0047] See also Figure 11 , the detection point on the coil is the standard line. During the continuous feeding of the coil, the relative positions of the first camera trolley 705 and the second camera trolley 709 remain stable. When the first camera trolley 705 and the second camera trolley 709 detect the corresponding standard lines at the same time, it indicates that the continuous feeding of the coil is synchronized. When the left longitudinal standard line deviates, the first camera trolley 705 will first deviate following the longitudinal standard line. After the paper cutting is determined, the relative positions of the first camera trolley 705, the second camera trolley 709 and the two slitting knives 12 will remain unchanged. If the first camera trolley 705 deviates following the standard line at this time, the second camera trolley 709 and the two slitting knives 12 will move synchronously with the first camera trolley 705.

[0048] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
