Abstract
Method and device (10) to manage a coiler apparatus (11) associated with a distributor (15), in which there is at least an exit of the feeder (21) of hot or cold semi-worked metal products, and with a reel (16), both being respectively moved with suitable controlled movement and rotation means, able to manage the coiling obtaining coils with desired characteristics.
Claims6
A management method for a coiler apparatus provided with a distributor, in which there is at least an exit of the feeder of semi-worked hot or cold metal products, a reel, and a management device comprising a video recording system focusing on said semi-worked metal product, said distributor and said reel being respectively moved by suitable controlled movement and rotation means, wherein said management method comprises:
- a step of inserting data in a control and command unit of said management device of the reference operating coiling parameters, said reference operating parameters being at least a desired angle of inclination (αSETi,l), and the equivalent diameter (DSETi,l) of said semi-worked metal product to the i-th rotation of said reel and to the l-th layer of the coil being formed, said angle of inclination (αSETi,l) being defined between the axis of said exit from the feeder and the instantaneous coiling point of said semi-worked metal product on said reel,
- a step of collecting the images from said video recording system during coiling, the collecting of the images being coordinated with the coiling speed;
- a step of processing the images and calculating continuously at least the operating parameters (αi,l, Di,l) by means of a processing and calculating unit of said management device, said operating parameters being at least said angle of inclination (αi,l) and said equivalent diameter (Di,l) of said semi-worked metal product;
- a step of comparing said operating parameters (αi,l, Di,l) obtained from the collection of images with said reference operating parameters (αSETi,l, DSETi,l) inserted in the control and command unit;
- a step of converting the possible differences between said reference operating parameters (αSETi,l, DSETi,l) and said operating parameters obtained (αi,l, Di,l), into coordinated variations (ΔVDFB, ΔVRFB) of the speed of movement (VD) of said distributor and/or of the speed of rotation (VR) of said reel;
- a step of coordinated adjustment of the speed of movement (VD) of said distributor and of the speed of rotation (VR) of said reel.
A management device for a coiler apparatus provided with a distributor, in which there is at least one exit of a feeder of hot or cold semi-worked metal products, and a reel, respectively moved by suitable controlled movement and rotation means, said management device comprising a video recording system configured to acquire images of said semi-worked metal product, wherein said management device comprises:
- a processing and calculating unit configured to process said images and calculate continuously the equivalent diameter (Di,l) of said semi-worked metal product and the angle of inclination (αi,l) defined between the axis of said exit of the feeder and the instantaneous coiling point of said semi-worked metal product on said reel;
- a control and command unit configured to control said operating parameters (αi,l, Di,l) obtained with reference operating parameters (αSETi,l, DSETi,l) previously supplied, and to command in a coordinated manner said movement and rotation means of said distributor and said reel.
