Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of deviation correction, in particular to a deviation correction control system. Background Art
[0002] At present, in the industrial production process, in order to facilitate transportation and storage, many raw materials are wound and rolled on reels. The coils must be stretched before formal processing. However, it is difficult to keep the coils stretched straight during the stretching process, and it is inevitable that the coils will deviate, resulting in damage to the coils.
[0003] However, most of the existing web-coil correction systems are installed after debugging, and their correction accuracy is low, which has certain limitations in actual use. Utility Model Content
[0004] In order to solve the deficiencies in the prior art, the utility model provides a deviation correction control system.
[0005] The technical solution of the utility model is:
[0006] The utility model provides a deflection correction control system, a deflection correction sensor, a deflection correction controller, and a deflection correction driver; the deflection correction sensor is fixedly arranged on the side of a conveyor belt for conveying coiled materials through a bracket, the fixed end of the deflection correction driver is fixedly arranged below the conveyor belt, and the output end is connected with a deflection correction guide; the deflection correction sensor and the deflection correction driver are electrically connected to the deflection correction controller respectively; the deflection correction sensor is used to detect the offset signal of the coiled material during the stretching process and transmit the offset signal of the coiled material to the deflection correction controller, and then the deflection correction controller controls the deflection correction driver to drive the coiled material to move on the left and right sides of its stretching direction through the deflection correction guide.
[0007] Furthermore, the fixed end and the output end of the correction driver are both rotatably connected with a T-shaped fixing block, the non-rotating end of the T-shaped fixing block at the output end is fixedly connected to the correction guide bolt, and the non-rotating end of the T-shaped fixing block at the fixed end is fixedly connected to the bottom surface of the support frame for supporting the conveyor belt.
[0008] Furthermore, the deviation correction driver is a servo motor linear driver.
[0009] Furthermore, the deviation correction sensor is a photoelectric sensor.
[0010] Furthermore, the correction sensor is an ultrasonic sensor.
[0011] Furthermore, the correction sensor is a HCCD sensor.
[0012] Furthermore, the correction controller is an EAC-A12 controller.
[0013] The beneficial effects achieved by the utility model are:
[0014] The utility model monitors the deviation of the coil by means of a deflection correction sensor, and controls the deflection correction driver by means of a deflection correction controller to drive the deflection correction guide mechanism to adjust the position of the coil, thereby ensuring that the coil is not damaged due to deflection during the stretching process. Since the deflection correction driver and the deflection correction sensor cooperate with each other, the deflection correction accuracy is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic diagram of the framework of the deviation correction system in the utility model. DETAILED DESCRIPTION
[0016] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.
[0017] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0018] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0019] like Figure 1 As shown, a deflection correction control system of the utility model comprises a deflection correction sensor, a deflection correction controller and a deflection correction driver; the deflection correction sensor is fixedly mounted on the side of a conveyor belt for conveying coiled materials through a bracket, the fixed end of the deflection correction driver is fixedly mounted below the conveyor belt, and the output end is connected with a deflection correction guide, the deflection correction sensor and the deflection correction driver are electrically connected to the deflection correction controller respectively; the deflection correction sensor is used to detect the offset signal of the coiled material during the stretching process and transmit the offset signal of the coiled material to the deflection correction controller, and then the deflection correction controller controls the deflection correction driver to drive the coiled material to move on both sides of its stretching direction through the deflection correction guide;
[0020] The fixed end and the output end of the correction driver are both rotatably connected with a T-shaped fixing block, the non-rotating end of the T-shaped fixing block at the output end is fixedly connected to the correction guide bolt, and the non-rotating end of the T-shaped fixing block at the fixed end is fixedly connected to the bottom surface of the support frame for supporting the conveyor belt; thereby realizing a variety of installation angles, which can be installed horizontally with the bracket or at an inclined angle, thereby improving its practicality.
[0021] The specific structure of the correcting guide is not limited, as long as it can be fixedly connected to the correcting driver and can drive the coil to move on both sides of its stretching direction, such as a robot, a clamping member, a pushing member, etc.
[0022] The specific model of the correction controller is EAC-A12 controller; the EAC-A12 controller can be connected to a variety of different types of correction sensors and drivers, such as ultrasonic, photoelectric, HCCD and other correction sensors, and supports multiple correction modes such as LPC, PEC edge following, CPC centering, SPC misalignment (snake-shaped), etc.
[0023] The deflection correction sensor is a photoelectric sensor; during operation, the edge of the coil is located on the light source facing the photoelectric sensor, and the sensing signal of the photoelectric sensor is the area of the light source covered by the edge of the coil. During operation after debugging, the edge of the coil is just located on the light source facing the photoelectric sensor. During the unwinding and stretching process of the coil, the offset occurs, and the edge of the coil must have offset the light source facing the photoelectric sensor. In this way, the area of the coil edge sensed by the photoelectric sensor is smaller or larger than the initial position, and the offset of the coil is obtained.
[0024] The correcting sensor is an ultrasonic sensor; it is used to detect the edge position of the coil. Compared with the photoelectric sensor, it is not affected by the transparency of the material, so it does not need to be calibrated when used, which is very convenient. It is suitable for edge tracking applications of airtight materials (such as plastics, films, paper, etc.).
[0025] The deflection correction sensor also includes an HCCD sensor, which is used to detect the edge position and contrast edge, line, pattern, etc. of the tracking coil.
[0026] The correction drive is a servo motor linear drive; compared with other types of motors, it has the characteristics of high efficiency, fast speed, short response time, large starting torque, precise braking, and maintenance-free. The transmission part uses a high-precision ball screw with high transmission efficiency, small backlash, and precise positioning, and is suitable for high-speed and precise correction applications.
[0027] The above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
