METHOD AND DEVICE FOR POSITIONING A COMPONENT
The invention relates to a method and device for positioning a component. A hydraulic drive displaces the component along a guide. A position marking for the component is read by at least one sensor. An output signal is transmitted to a controller and the controller regulates a position of the component by means of a variation in the supply of fluid depending on the output signal from the sensor.
1 . A method for positioning a component, in which a fluid drive moves the component along a guide, wherein at least one positioning marker of the component is detected by at least one sensor; an output signal of the sensor is supplied to a control unit; and the control unit automatically controls a position of the component by varying the supply of the fluid as a function of the output signal of the sensor.
2 . A method in accordance with claim 1 , wherein a pneumatic drive is used as the fluid drive.
3 . A method in accordance with claim 1 , wherein a hydraulic drive is used as the fluid drive.
4 . A method in accordance with claim 1 , wherein the fluid drive carries out a linear movement.
5 . A method in accordance with claim 1 , wherein the sensor detects the position of a plurality of markers.
6 . A method in accordance with claim 1 , wherein optical means are used to detect the position.
7 . A method in accordance with claim 1 , wherein magnetic means are used to detect the position.
8 . A method in accordance with claim 1 , wherein the control unit drives an electrically controllable valve.
9 . A method in accordance with claim 1 , wherein a piston that moves within a cylinder is used as the fluid drive.
10 . A method in accordance with claim 1 , wherein the piston can be acted upon on two sides by the actuating pressure.
11 . A method in accordance with claim 1 , wherein a linear motor is used as the sensor.
12 . A method in accordance with claim 1 , wherein the device is used in a blow-molding machine.
