Device for controlling the drive of a reel
First Claim
1. A device for providing wire and controlling the drive of a reel, comprising:
- a wire supply in the form of a coil on the reel, from which the wire, through interposition of a tensioning device, is spring-pretensioned in one deflection direction and effective up to a maximum deflection for approximated stabilization of a wire tension to a wire infeed device for a downstream positioned wire processing machine;
whereby a velocity curve of an infeed rate of the wire infeed device in accordance with a preset velocity-time profile is controlled by a control unit of the wire processing machine, and whereby a rotation speed of the reel in accordance with a preset rotation speed-time profile is controlled by a drive control of the reel, whereby the drive control of the reel starts the rotation in accord with the rotation speed-time profile of the reel set forward by a preset time interval with respect to the velocity-time profile of the infeed rate.

Abstract
With a device for controlling the drive of a reel, with a wire supply in the form of a coil of said wire supply, from which the wire, through interposition of a tensioning device, which is spring-pretensioned in one deflection direction and effective up to a maximum deflection, for approximated stabilization of the wire tension of a feed installation of the wire infeed of a downstream positioned wire processing machine, the velocity curve of the feed rate of the wire infeed in accordance with a preset velocity-time profile is controlled by a control unit of the wire processing machine, and whereby the curve of the rotation speed of the reel in accordance with a preset rotation speed-time profile is controlled by the drive control of the reel, whereby the drive control of the reel sets the rotation speed-time profile of the reel, with regard to the velocity-time profile of the feed rate, forward by a preset time interval.

9. A device for providing wire and for controlling the drive of a reel, the device comprising:
-
a reel containing a supply of wire in the form of a coil; a wire infeed device downstream of the reel adapted to receive the wire from the reel and provide it to a wire processing machine; a tensioning device interposed along the wire extending from the reel to the wire infeed device to spring-pretension the wire for stabilization of a wire tension of the wire; and wherein a velocity curve of a infeed rate of the wire to the wire infeed device in accordance with a preset velocity-time profile is controlled by a control unit of the wire processing machine, and wherein a rotation speed curve of the reel in accordance with a preset rotation speed-time profile is controlled by a drive control of the reel, and wherein the drive control of the reel starts the rotation of the reel in accord with the speed-time profile and set forward by a preset time interval with regard to the velocity-time profile of the feed rate. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of providing wire, the method comprising:
-
providing wire to a wire feed device for a wire processing machine from a wire supply in the form of a coil on a reel, controlling the speed of rotation of the reel in accordance with a preset rotation speed-time profile, and causing the wire from the reel to be received at a wire infeed downstream of the reel at a feed rate in accordance with a preset velocity-time profile, wherein the preset rotation speed-time profile corresponds to the preset velocity-time profile. - View Dependent Claims (18, 19)
