Technical Field
[0001] The invention relates to the technical field of deviation correction equipment, and in particular to a bidirectional deviation correction device. Background Art
[0002] During the movement of the material, in order to ensure that the material moves in the same position, a correction device is generally installed in the material conveyor, and the correction sensor performs real-time monitoring. Once it exceeds the set range of the correction sensor, the correction actuator is immediately controlled to drive the correction device of the conveying material to perform corresponding deviation and swing movements to adjust the movement position of the material.
[0003] However, during the normal conveying of the sheet, due to the production process requirements, there are some specific situations where the sheet needs to be retracted along the original route. For example: to check the sheet that has just traveled, the sheet needs to be rewound and checked, and it is necessary to ensure that the position of the sheet remains unchanged during the rewinding process; due to some technical bottlenecks, the correction device can only guarantee the sheet position in one direction, and the sheet can easily deviate from the original position during the rewinding process. In this case, if the material is discharged directly along the original route, since the original correction device controls the fixed conveying roller to perform oscillating motion, it is difficult to return the sheet to its original position within a short distance and short time after discharging along the original route, thereby affecting product quality. This situation is absolutely not allowed in the production process. Summary of the invention
[0004] In order to overcome the defects of the prior art, the present invention provides a bidirectional correction device. By setting a three-layer correction frame, correction devices with opposite correction directions are installed in the second frame and the third frame. Regardless of whether the material is moving forward or backward, the conveying position of the material can be well controlled, thereby ensuring the production process requirements and product quality.

[0010] The feed end and the discharge end are respectively installed with correction sensors for sensing the side boundaries of the sheet, and the two correction sensors are respectively electrically connected to the second correction actuator and the third correction actuator one by one.
[0011] Furthermore, the second deflection-correcting actuator is close to the feed end, the second deflection-correcting actuator is electrically connected to the deflection-correcting sensor close to the feed end, the second positioning rotation fulcrum pin is close to the discharge end and is located directly below the conveying roller, and the second offset guide rail is composed of a plurality of second guide rail groups symmetrically arranged on both sides of the second deflection-correcting actuator, and the plurality of second guide rail groups are arranged in an "eight" shape from the discharge end to the feed end and gradually shrink inward;
[0012] The third deflection-correcting device is installed at an opposite position to the second deflection-correcting device, and the third deflection-correcting actuator is electrically connected to a deflection-correcting sensor close to the discharge end.
[0013] Furthermore, the two correction sensors are located on the same side of the three-layer correction frame.

[0023] The second frame 12 is equipped with a second deflection correcting device, and the third frame 13 is equipped with a third deflection correcting device, and the deflection correcting direction of the second deflection correcting device is opposite to that of the third deflection correcting device;
[0024] The second deflection-correcting device includes a second deflection-correcting actuator 21, a second offset guide rail 22 and a second positioning rotating fulcrum pin 23. A first roller group 111 matched with the second offset guide rail 22 is installed at the bottom of the first frame 11. The second positioning rotating fulcrum pin 23 is fixedly arranged on the top of the second frame 12. The first frame 11 is rotatably sleeved on the second positioning rotating fulcrum pin 23. Under the power of the second deflection-correcting actuator 21, the first frame 11 moves in a directional manner along the second offset guide rail 22 with the second positioning rotating fulcrum pin 23 as the center, thereby driving the conveying roller 103 on the top of the first frame 11 to perform a deflection motion with the vertical position of the second positioning rotating fulcrum pin 23 as the center, thereby ensuring the accuracy of the conveying position of the sheet 10.
[0025] The third deviation-correcting device includes a third deviation-correcting actuator 31, a third offset guide rail 32 and a third positioning rotating fulcrum pin 33. A second roller group 121 matched with the third offset guide rail 32 is installed at the bottom of the second frame 12. The third positioning rotating fulcrum pin 33 is fixedly arranged on the top of the third frame 13. The second frame 12 is rotatably sleeved on the third positioning rotating fulcrum pin 33. Under the power of the third deviation-correcting actuator 31, the first frame 11 and the second frame 12 as a whole move in a directional manner along the third offset guide rail 32 with the third positioning rotating fulcrum pin 33 as the center, thereby driving the conveying roller 103 on the top of the first frame 11 to perform an eccentric motion with the vertical position of the third positioning rotating fulcrum pin 33 as the center, thereby ensuring the accuracy of the conveying position of the sheet 10.
[0026] The feed end 101 and the discharge end 102 are respectively installed with correction sensors 4 for sensing the side boundaries of the sheet 10 , and the two correction sensors 4 are respectively electrically connected to the second correction actuator 21 and the third correction actuator 31 one by one.
[0027] As a preferred embodiment of the present application, the second deflection correcting actuator 21 is close to the feed end 101, the second deflection correcting actuator 21 is electrically connected to the deflection correcting sensor 4 close to the feed end 101, the second positioning rotating fulcrum pin 23 is close to the discharge end 102, and is located directly below the conveying roller 103 at the discharge end 102, the second offset guide rail 22 is composed of two groups of second guide rail groups 221 symmetrically arranged on both sides of the second deflection correcting actuator 21, and the two groups of second guide rail groups 221 are arranged in an "eight" shape from the discharge end 102 to the feed end 101 and gradually shrink inwardly. Under the action of the second deflection correcting actuator 21, the first frame 11 moves in a directional manner along the second offset guide rail 22 with the second positioning rotating fulcrum pin 23 as the center of the circle, thereby driving the two conveying rollers 103 at the top of the first frame 11 to perform a deflection motion along the second offset guide rail 22 with the center of the left end conveying roller 103 as the center of the circle, so that the web 10 is rolled up at a suitable position;
[0028] The third deflection correcting device is installed at an opposite position to the second deflection correcting device. The third deflection correcting actuator 31 is close to the discharge end 102. The third deflection correcting actuator 31 is electrically connected to the deflection correcting sensor 4 close to the discharge end 102. The third positioning rotation fulcrum pin 33 is close to the feed end 101 and is located directly below the conveying roller 103 at the feed end 101. The third offset guide rail 32 is composed of two groups of second guide rail groups 321 symmetrically arranged on both sides of the third deflection correcting actuator 31. The third guide rail group 321 is arranged in an "eight" shape from the feed end 101 to the discharge end 102 and gradually shrinks inward. Under the action of the third deviation correction actuator 31, the first frame 11 and the second frame 12 as a whole move in a directional manner along the third offset guide rail 32 with the third positioning rotation fulcrum pin 33 as the center of the circle, thereby driving the two conveying rollers 103 on the top of the first frame 11 to perform an eccentric motion along the third offset guide rail 32 with the center of the right end conveying roller 103 as the center of the circle, so that the sheet 10 is unwound at a suitable position.
[0029] Therefore, when the web 10 is rolled up, the second deviation-correcting device controls the web 10 to be rolled up at a suitable position, and when the web 10 needs to return along the original path, the third deviation-correcting device controls the web 10 to be unrolled at a suitable position. Regardless of rolling up or unrolling, the travel position of the web 10 can be well controlled, which is convenient for checking the web 10 that has just been rolled up, and for re-rolling the rolled web 10 after returning along the original path, thereby effectively improving the conveying efficiency of the web 10, ensuring the production process requirements, and ensuring product quality. At the same time, after checking the quality problems of the rolled web 10, the unrolling process can be carried out in time, avoiding the failure of the entire batch of webs 10, and effectively saving the cost of the enterprise.
[0030] It should be noted that the present application only shows a preferred embodiment, and technicians in this technical field can easily think of swapping the positions of the second correcting device and the third correcting device, that is, controlling the material sheet to be unwound at a suitable position by the second correcting device and to be rewound at a suitable position by the third correcting device, which is still within the protection scope of the present application.
[0031] Preferably, the two correction sensors 4 are both located on the rear side of the three-layer correction frame 1. Obviously, technicians in this technical field can also easily think of: setting the two correction sensors 4 on the front side of the three-layer correction frame 1, or one on the front side and the other on the rear side, as long as it can face the side boundary of the material 10 to detect the position of the material 10 being rolled up and / or unrolled.
