Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a deviation rectifying system for coiling of a pulling straightening unit comprises a base guide rail 2 and a coiler 4, wherein a sliding block connected to the bottom of the coiler 4 is clamped on the base guide rail 2, and the side surfaces of a C-shaped frame 51 and the coiler 4 are connected with a deviation rectifying power assembly 3.

The position transmitter 34 is installed on the deviation-correcting oil cylinder 31 and connected with the deviation-correcting controller 1 to measure the displacement of the deviation-correcting telescopic rod 32, and the position transmitter 34 is provided with a position sensor which is connected with the deviation-correcting controller 1.

Following to the correction system that straightening and withdrawal unit coiled from centering function brief description as follows:

when the self-centering function is needed, a 'self-centering' button of the operating platform is pressed, and at this time, the coiling machine 4 is driven by the deviation-correcting oil cylinder 31 to automatically move to the center position, namely the coiling wheel 41 is positioned on the center line of the whole production line. This is generally suitable for the operation of the loading belt sleeve, so that the aluminium coil is initially loaded in the middle of the coiler 4, i.e. so as to ensure as much as possible that the aluminium coil to be initially coiled is in the middle position.

Both "self-centering" and "automatic" are one way of automatically controlling a system, the process and control being referenced to an automatic system control block diagram such as that of fig. 1. But the feedback reference of the two is different. The "self-centering" is referred to the reel-up 4 and the signal is derived from the displacement sensor of the reel-up 4. And "auto" refers to the center position of the upper and lower electro-

optical heads

52, 54, and the signal is derived from the upper and lower electro-

optical heads

52, 54.

The photoelectric detection assembly 5 comprises a C-shaped frame 51, an upper photoelectric head 52, a side arm 53 and a lower photoelectric head 54, wherein one end of the side arm 53 is mounted on the side wall of the winding frame 44, the other end of the side arm 53 is connected with a port of the C-shaped frame 51, the upper photoelectric head 52 and the lower photoelectric head 54 are respectively fixed on opposite ports of the C-shaped frame 51, the upper photoelectric head 52 and the lower photoelectric head 54 are connected to the deviation correction controller 1 through conducting wires, and photoelectric sensors are arranged in the upper photoelectric head 52 and the lower photoelectric head 54.

The side arm 53 is connected with the winding frame 44 through a driving motor and a lead screw, the side arm 53 is sleeved on the lead screw and meshed with the lead screw, and the driving motor is connected with the lead screw and used for driving the side arm 53 to horizontally move. The servo valve ammeter connected in series on the electro-hydraulic servo valve 33 is connected with the deviation correction controller 1.

The main functions of the deviation correcting system comprise three working modes of manual operation, automatic operation and self-centering operation, and the specific working process and principle are as follows:

when the system is turned on and the external hydraulic power source has been turned on, the operator presses the "manual" button on the console, at which time the system is in manual mode with an indication. The deviation correction cylinder 31 can be operated by pressing a "move left" or "move right" button, and the coiler 4 can move left or right. This allows for flexible manual adjustment. The photoelectric detection assembly 5 detects the automatic deviation rectifying function of the aluminum coil.

Both the "gain" and "zero offset" response of the system can be adjusted by the skew controller 1. When the upper photoelectric head 52 and the lower photoelectric head 54 are completely shielded, the feedback voltage signal has + 5V; when the upper photoelectric head 52 and the lower photoelectric head 54 are not shielded by the aluminum coil, the voltage is fed back to-5V; and when the shielding is half, the probe outputs 0V.

When the head of the aluminum coil is fixed on the winding wheel 41 of the coiler 4, the tension of the aluminum coil is established, and the speed of the production line is slowly established, the automatic deviation rectifying function needs to be put into operation. The operator presses the "auto" button on the console, which is when the system is in the auto mode and instructed.

When the 'automatic' button is pressed, the driving motor drives the C-shaped frame 51, the upper photoelectric head 52 and the lower photoelectric head 54 to move towards the central line direction of the aluminum coil, and after the upper photoelectric head 52 and the lower photoelectric head 54 seek edges in place, the C-shaped frame 51 stops moving. The upper photoelectric head 52 and the lower photoelectric head 54 can sense a signal of the shielding amount of the aluminum coil, and the signal is output to the electro-hydraulic servo valve 33 after system operation processing, so as to drive the deviation-rectifying oil cylinder 31, drive the coiling machine 4 and the aluminum coil to move left and right, and enable the edge of the aluminum coil to tend to the central line of the upper photoelectric head 52 and the lower photoelectric head 54 all the time, thereby realizing the automatic deviation-rectifying function. When exiting the automatic mode, the photo-detection unit 5 and the C-shaped frame 51 are automatically retracted to the original positions.

In summary, the following steps: the deviation rectifying system for the coiling of the pulling straightening unit has the advantages that the forward and backward movement, the left and right movement, and the deviation rectification or deviation rectification are relative to the advancing central line of the aluminum coil, so that the deviation rectifying system is suitable for edge searching of materials with different bandwidths. The electro-hydraulic servo valve 33 drives the deviation-correcting oil cylinder 31 to move, so that the coiling machine 4 and the aluminum coil wound on the coiling machine 4 are pulled to move left and right. A position transmitter 34 mounted on the reel-up 4 for detecting the real time position of the reel-up 4.
