Abstract
In the tape winder for winding a tape on a reel to form a tape roll, a nozzle which blows a gas toward an outer peripheral surface of the tape roll at a winding time of the tape is fixed on a slider, which is slidably supported on a rail. In this way, the nozzle is supported movably forward and backward with respect to the tape roll. Moreover, the nozzle is pressed toward the tape roll by an air cylinder with a constant pressing force. Thus, the nozzle is allowed to accurately follow an outer peripheral surface of the tape roll, and a constant pressure can be applied to the outer peripheral surface of the tape roll. Consequently, the tape can be wound with an adequate winding tightness.
Claims25
A tape winder, comprising:
- a winding shaft which winds a tape to form a tape roll;
- a nozzle which blows a gas toward an outer peripheral surface of the tape roll at a winding time of the tape;
- a support device which movably supports the nozzle forward and backward with respect to the outer peripheral surface of the tape roll;
- and
- a pressing device which presses the nozzle supported by the support device toward the outer peripheral surface of the tape roll with a constant pressing force,
- wherein the tape is wound at a position in which a pressing force of the pressing device and a repulsive force in a space between the nozzle and the tape roll are balanced.
A tape winder, comprising:
- a winding shaft which winds a tape to form a tape roll;
- a nozzle which blows a gas toward an outer peripheral surface of the tape roll at a winding time of the tape;
- and
- a tape position control device which controls a width direction position of the tape to be wound, the tape position control device being provided in an upstream side vicinity of the nozzle with respect to a winding direction of the tape.
A tape winder, comprising:
- a winding shaft which winds a tape to form a tape roll;
- a nozzle which blows a gas toward an outer peripheral surface of the tape roll at a winding time of the tape;
- a moving device which moves the nozzle in forward and backward directions with respect to the winding shaft;
- a distance sensor which measures a distance between the nozzle and the outer peripheral surface of the tape roll;
- and
- a control device which controls the moving device according to measurement values outputted from the distance sensor so that the distance between the nozzle and the outer peripheral surface of the tape roll is kept constant.
