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 patterns, 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 cause the finished product quality to fail to meet the standards. To solve this problem, it is urgent 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.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: An active deviation rectifying slitter includes a frame, a camera assembly. The coiled material passes in and out of 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 in-out direction, the first deviation rectifying assembly deflects relative to the frame to correct the cutting position of the cutting trolley. 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 in-out direction of the coiled material. When the coiled material has a deviation relative to the in-out direction, the slitting knives move horizontally synchronously with the paper to correct the cutting position of the slitting knives.

[0005] Preferably, a second paper pressing assembly is further provided inside the first deviation rectifying assembly, and the second paper pressing assembly covers and presses the coiled material.

[0006] Preferably, when the cutting trolley cuts the coiled material, the coiled material is in a stationary state relative to the first paper pressing assembly.

[0007] Preferably, the first deviation rectification assembly includes an operating table installed in the frame. The coil material passes in and out of the operating table. The operating table is equipped with a second cross bar which has a track, and the cutting trolley is slidably engaged with the track. The first deviation rectification assembly further includes a first driving motor installed at the lateral position of the operating table, and a first synchronous belt system connected to the cutting trolley. The first driving motor is drivingly connected to the first synchronous belt system to drive the cutting trolley to move linearly along the track.

[0008] Preferably, the bottom of the operating table has a rotating shaft, and the structure cooperating with the rotating shaft is a shaft seat installed in the frame. The relative position of the rotating shaft is a transfer member which is shaft-connected to the operating table. There is also a driving part which drives the transfer member to move in the direction of the coil material passing in and out, so that the operating table deflects at an angle with the rotating shaft as the fulcrum.

[0009] Preferably, the tool fixing part in the second deviation rectification assembly is a tool bar. The structure for driving the tool fixing part in the second deviation rectification assembly includes a bench installed outside the frame. The bottom of the bench is a second motor, and the top of the second motor is a lead screw structure. The second motor is the power source of the lead screw structure. It further includes a tool bar seat connected to the lead screw structure. When the second motor drives the lead screw structure to move, the tool bar seat drives the tool bar to move in the direction perpendicular to the direction of the coil material passing in and out.

[0010] Preferably, the first paper pressing assembly is composed of an upper paper pressing structure and a lower paper pressing structure. Among them, the upper paper pressing structure is above the coil material, and the lower paper pressing structure is below the coil material. The upper paper pressing structure can move in the height direction so that the coil material is clamped between the upper paper pressing structure and the lower paper pressing structure.

[0011] Preferably, the camera assembly includes two independent camera trolleys. Among them, the camera trolley can move in the direction perpendicular to the direction of the coil material passing in and out, and the camera trolley can also photograph a series of continuous detection points on one side of the coil material.

[0012] Preferably, when the two camera trolleys detect the detection points in the corresponding areas successively, the first deviation rectification assembly deflects at an angle relative to the frame.

[0013] Preferably, when the detection points detected by the two camera trolleys in the corresponding areas deviate, the two camera trolleys will move synchronously and record the deviation amount, so that the second deviation rectification assembly moves horizontally relative to the frame based on the deviation amount.

[0014] The beneficial effects of the present invention are as follows: In view of the problem that the coil material is prone to deviation during transportation, the present invention specially designs two sets of deviation rectification systems. The two sets of deviation rectification systems capture the deviation state of the coil material based on the video system, and enable the corresponding deviation rectification system to control the tool assembly to move, so as to timely adjust the cutting position and improve the cutting accuracy.

[0018] The specific embodiments of the present invention will be described below with reference to the drawings.

[0019] Embodiment 1 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 2 shown, the frame 2 is a frame structure, and its main structure is a base 201. On both sides of the base 201 are a first baffle 202 and a second baffle 203 (there is a gas distribution system 11 on one side of the second baffle 203, 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 a machine cover 1. Specifically, the machine cover 1 includes a first cover 101 covering the first baffle 202, a third cover 103 covering the second baffle 203, and a second cover 102 covering the first cross bar 204. The second cover 102 has an observation window 104, and a touch screen 105 is also installed in the first cover 101.

[0020] Please refer to Figure 1 and Figure 2 and take Figure 9 as a reference. The slitter proposed in this embodiment is used for slitting 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.

[0021] 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 to each other.

[0022] Please continue to refer to Figure 8The two camera trolleys are the first camera trolley 705 and the second camera trolley 709, and the two camera trolleys can move in a direction perpendicular to the direction of the coil in and out. Figure 8 , as the bracket part of the two camera trolleys, the fourth cross bar 701 is a hollow structure, and its two sides are respectively fixed to the first baffle 202 and the second baffle 203, and each camera trolley has a bracket. Specifically, the bracket for fixing the first camera trolley 705 is the first camera trolley bracket 704, and the bracket for fixing the second camera trolley 709 is the second camera trolley bracket 708. The above-mentioned trolley brackets are installed on the fourth cross bar 701 through clamps. Further description, each trolley bracket has a set of driving structure, wherein the structure for driving the first camera trolley bracket 704 is the second synchronous belt system 703 inserted into the fourth cross bar 701, and the third motor 702 installed on the outside of the first baffle 202 and connected to the second synchronous belt system 703. The third motor 702 can move the first camera trolley bracket 704 relative to the fourth cross bar 701 when driving the second synchronous belt system 703 to operate. As mentioned above, the structure for driving the second camera trolley bracket 708 is the third synchronous belt system 707 and the fourth motor 706 installed on the outside of the first baffle 202. The above-mentioned second camera trolley bracket 708 is connected to the third synchronous belt system 707. After the connection, the fourth motor 706 can move the second camera trolley bracket 708 relative to the fourth cross bar 701 when driving the third synchronous belt system 707 to operate.

[0023] See also Figure 7 The second deflection-correcting component 6 includes a driving structure and a tool fixing part. The tool fixing part is used to fix two slitting knives 12. The slitting knives 12 can cut the coiled material in a moving state. The above-mentioned driving structure can drive the tool fixing part to move in a direction perpendicular to the coiled material inlet and outlet direction. The function of the second deflection-correcting component 6 is to make the slitting knives 12 move synchronously with the paper when the coiled material photographed by the camera component 7 is laterally offset relative to the inlet and outlet direction, so as to correct the cutting position of the slitting knives 12.

[0024] Please continue reading Figure 7 The tool fixing part in the second correcting component 6 is a tool rod 605, one end of which is movably mounted on the second baffle 203. The structure for driving the tool rod 605 in the second correcting component 6 includes a stand 601 mounted on the outside of the frame 2. Specifically, the stand 601 is mounted on the outside of the first baffle 202. A second motor 602 is provided at the bottom of the stand 601. A screw structure 603 is provided at the top of the second motor 602. The second motor 602 is connected to the screw structure 603 through a belt. The object driven by the screw structure 603 is a tool rod seat 604. The other end of the tool rod 605 is fixed on the tool rod seat 604. When the second motor 602 drives the screw structure 603, the tool rod seat 604 can move the tool rod 605 in a direction perpendicular to the direction of the coil entering and exiting.

[0025] See also Figure 4 and Figure 6 The 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 coil, and the lower paper pressing structure 8 is below the coil. Both the upper paper pressing structure 5 and the lower paper pressing structure 8 can roll in contact with the coil. 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 coil, so that the coil is clamped between the upper paper pressing structure 5 and the lower paper pressing structure 8 for stable movement.

[0026] See also Figure 6 The upper paper pressing structure 5 includes a third cross bar limiting portion 501 respectively installed on the first baffle 202 and the second baffle 203, and also includes a third cross bar 502. Both ends of the third cross bar 502 are constrained by the third cross bar limiting portion 501, and the constrained third cross bar 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 a glue wheel pressure rod 504 installed at the bottom of the third cross bar 502 for rolling contact with the coil.

[0027] 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 plate 202 and the second baffle plate 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 plate 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 coil during the movement, and clamping the coil between the two.

[0028] See also Figure 5The first deflection correction component 4 is equipped with a movable cutting trolley 3, and the cutting trolley 3 can cut the coiled material in a stationary state while moving. The first deflection correction component 4 is connected to the frame 2 axis. In this embodiment, when the coiled material photographed by the camera component 7 is angularly offset relative to the in-and-out direction, the first deflection correction component 4 is deflected relative to the frame 2 to correct the cutting position of the cutting trolley 3. The first deflection correction component 4 includes an operating table 401 installed in the frame 2, and the coiled material enters and exits from the operating table 401. The operating table 401 is equipped with a second cross bar 402, and the second cross bar 402 has a track 406 for slidingly cooperating with the cutting trolley 3. The first deflection correction component 4 also includes a first drive motor 405 installed at the lateral position 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.

[0029] 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, and the adapter 404 is connected to the operating table 401 axis. There is also a driving unit 403, and the driving unit 403 is installed on Figure 2 The extension frame 205 shown further illustrates that the driving unit 403 is consistent with the driving structure for driving the knife rod 605 to move in the second deviation 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 arrangement, when the driving unit 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 a fulcrum.

[0030] Please refer again Figure 5 The first deviation-correcting component 4 is also provided with a second paper pressing component 9. Unlike the first paper pressing component, the second paper pressing component 9 is provided inside the operating table 401. Its function is to cover and press the coiled material, so as to facilitate the cutting trolley 3 to cut the coiled material in the area (the cutting tool used by the cutting trolley 3 is a disc-shaped cutting tool, which is rolled and installed in the cutting trolley 3. If the coiled material is not pressed tightly, the cutting trolley 3 may have the risk of cutting off the coiled material). Please refer to Figure 5 There are two second cylinders 901 under the second cross bar 402, and a paper pressing board 902 is under the second cylinder 901. 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 travel range of the two second cylinders 901.

[0031] See also Figure 10, the detection points on the coil are standard lines. During the continuous feeding of the coil, S is the defined fixed width of the camera marking point. The first camera carriage 705 and the second camera carriage 709 will automatically run to find the standard side lines. If the first camera carriage 705 runs S1 to reach the standard side line and the second camera carriage 709 runs S2 to reach the standard side line, then the distance between the two standard side lines is S - (S1 + S2); during the continuous feeding of the coil, when the first camera carriage 705 and the second camera carriage 709 detect the standard lines simultaneously, the left and right feeding of the coil is synchronous; if the first camera carriage 705 detects the standard line first, the left side of the coil feeds ahead and the right side feeds behind, and the system will automatically calculate the deviation value S3 with the direction of "+"; if the second camera carriage 709 detects the standard line first, the right side of the coil feeds ahead and the left side feeds behind, and the system will automatically calculate the deviation value S3 with the direction of "-"; based on the data measured above, the deflection angle of the cardboard 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 rectification component 4.

[0032] Please refer to Figure 11 , the detection points on the coil are standard lines. During the continuous feeding of the coil, the relative positions of the first camera carriage 705 and the second camera carriage 709 remain stable. When the first camera carriage 705 and the second camera carriage 709 detect the corresponding standard lines simultaneously, it indicates that the continuous feeding of the coil is synchronous. When the left longitudinal standard line deviates, first, the first camera carriage 705 will follow the deviation of the longitudinal standard line. Since the cutting paper is determined, the relative positions of the first camera carriage 705, the second camera carriage 709, and the two slitting knives 12 will all remain unchanged. If the first camera carriage 705 follows the deviation of the standard line at this time, then the second camera carriage 709 and the two slitting knives 12 will all move synchronously with the first camera carriage 705.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0034] The above-described embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
