DETAILED DESCRIPTION
[0022] The present application will be further described below in combination with the drawings.
[0023] The directions involved in the present specification are based on the directions of the curtain fabric deviation correcting device when it is working normally, and are not limited by the directions when it is stored and transported. Only the relative positional relationship is represented, and the absolute positional relationship is not represented.
[0024] As Figure 1 andFigure 2 As shown in the drawings, a curtain yarn deviation rectifying device comprises a frame 1 and a deviation rectifying mechanism installed on the frame 1.
[0025] The frame 1 is fixed on a conveying line between a unwinding device and a composite device, so as to ensure that the curtain yarn 2 can pass through the deviation rectifying mechanism during conveying.
[0026] The deviation rectifying mechanism comprises a detection device, an adjusting device and a control system. The detection device is installed at the front end of the adjusting device and is used for detecting the deviation of the passing curtain yarn 2. The detection device comprises sensors arranged on the left and right sides of the curtain yarn 2, and the sensor signals are connected to the control system. When the curtain yarn 2 passes through, the sensor can detect the position of the curtain yarn 2 and transmit the signal to the control system.
[0027] The adjusting device comprises an adjusting frame 3 movably installed on the frame 1, a deviation rectifying roller 4 rotatably installed on the adjusting frame 3 and a driving device 5 for driving the adjusting frame 3 to move left and right. The driving device 5 is signal connected to the control system. The curtain yarn 2 is attached to the upper surface of the deviation rectifying roller 4 and generates a certain pressure with the deviation rectifying roller 4, so as to ensure that the curtain yarn 2 can follow the deviation rectifying roller 4 to generate a small amplitude of left and right adjustment during conveying, thereby rectifying the deviation.
[0028] In a specific embodiment, the sensor adopts a U-shaped sensor, the notch of the U-shaped groove 6 of which faces the direction of the curtain yarn 2, and the curtain yarn passes through the U-shaped groove 6 on the corresponding side. A light-receiving type photoelectric sensor is arranged on the U-shaped groove 6, which comprises a transmitting end arranged above the curtain yarn on the U-shaped groove 6 and a receiving end arranged at the bottom of the curtain yarn on the U-shaped groove 6. When the curtain yarn passes through, the light will be cut off, thereby triggering the sensor to output a signal. The photoelectric sensor arranged on both sides can capture the deviation information of the curtain yarn 2 in real time and accurately, and transmit the data to the control system.
[0029] As shown in the drawings, Figure 3 and Figure 4 As shown in the drawings, the installation mode of the left and right movement of the adjusting frame 3 is as follows:
[0030] The adjusting frame 3 is fixed with a sliding block 31 at the left and right ends, and the frame 1 is fixed with a guide rail 32 for the left and right sliding of the sliding block 31. The sliding block 31 slides left and right along the guide rail 32 to realize the left and right movement of the adjusting frame 3. The frame 1 is also fixed with the driving device 5, and the output shaft of the driving device 5 is fixed on the sliding block 31 and drives the sliding block 31 to slide left and right along the guide rail 32.
[0031] The guide rail 32 can be horizontally arranged, which can make the adjusting frame 3 only move horizontally, and in order to realize the left and right movement of the curtain yarn 2 in the deviation rectification process, two guide rails 32 are arranged in the embodiment, which are arranged on the left and right sides of the adjusting frame 3; the two guide rails 32 are inclined upward from the outside of the rack 1 to the middle, that is, the two guide rails 32 are in an eight-shaped structure. The bottom of the adjusting frame 3 is hinged to the sliding block 31; the driving device 5 is connected to any sliding block 31, so that the movement of the adjusting frame 3 can be realized. Because the bottom of the adjusting frame 3 is hinged to the sliding block 31, when the adjusting frame 3 moves left and right, a slight inclination will be generated, and when the curtain yarn 2 is conveyed forward, it will deviate to the lower side, so as to make the deviation rectification quickly respond. The control system intelligently commands the driving device 5 to act according to the detection data, so as to accurately adjust the position of the curtain yarn 2.
[0032] Further, the included angle between the guide rail 32 and the horizontal plane is 5°-20°, and the included angle in the embodiment is preferably 10°, so as to ensure that the curtain yarn 2 can quickly respond to the deviation rectification, and at the same time, the problem of over-deviation caused by too large inclination angle will not occur.
[0033] The driving device 5 can adopt an electric cylinder, and the extension direction of the output shaft of the electric cylinder is consistent with the extension direction of the guide rail 32. The output shaft of the electric cylinder is fixed on the sliding block 31, and the sliding block 31 is driven to move along the guide rail 32 through the extension and retraction movement of the electric cylinder.
[0034] In order to avoid the contact and friction between the curtain yarn 2 and the detection device, a transition shaft 7 is further arranged between the detection device and the adjusting device. The transition shaft 7 is rotatably installed on the rack 1 and arranged at the end of the detection device, so as to ensure that the curtain yarn can smoothly transition to the adjusting device.
[0035] In addition, in order to adapt to curtain yarns 2 with different widths, a spacing adjusting device 8 is arranged between the two sensors arranged on the left and right.

One sensor is installed on each sliding seat 82, and the distance between the two sensors can be adjusted by adjusting the position of the sliding seat 82, so as to adapt to curtain yarns with different widths.
[0036] The sliding driving device 83 can adopt a lead screw rotatably installed on the rack 1, and the lead screw is provided with a right thread at one end and a left thread at the other end. A lead screw nut is arranged on the right thread and the left thread respectively, and the two sliding seats 82 are fixed on different lead screw nuts. When the lead screw rotates, the two lead screw nuts will move relative to or away from each other along the lead screw, thereby driving the sliding seats 82 and the sensors to move. One end of the lead screw is fixed with a motor, and the rotation of the motor drives the rotation of the lead screw.
[0037] In order to improve the effect of rectification, the curtain yarn rectification device can be arranged in one or more groups side by side.
[0038] As Figure 1 , Figure 2 , Figure 3 and Figure 4 Commonly shown, a curtain yarn rectification device workflow:
[0039] When the curtain yarn is unwound and then enters the composite device, the two sides of the curtain yarn 2 pass through the U-shaped groove 6 respectively, when the curtain yarn 2 appears to be skewed, the skewed side will cut off the light, thereby triggering the sensor output signal; The signal is transmitted to the control system, and the control system controls the driving device 5 to stretch and retract, thereby controlling the position of the adjusting frame 3, thereby realizing the position adjustment of the curtain yarn 2, thereby realizing the rectification.
