Definitions
- the invention relates to a device for feeding the start end of a wire coil to a drawing system, having a base on which a holder is rotatably mounted and an arm connected to the holder, which has a gripping element at its end for grasping the start end of the wire coil.
- a device of this type known according to DD 41 927 has a holder on which a radially movable arm is arranged, the height of which can be varied by means of a lifting cylinder.
- the arm carries a gripping element at its free end.
- the gripping element is brought into the desired position by rotating and lifting or lowering the arm.
- the start end of the wire is fed via straightening rollers to a pair of clamping tongs that shows the material in the working direction. Then the actual wire drawing process follows.
- Such a device requires a considerable amount of space to enable the necessary rotary movements.
- the gripping elements must clamp the start end of the wire and additional devices for straightening the wire must be provided in the system.
- the object of the present invention is now to provide a device of the type mentioned at the outset which, on the other hand, considerably reduces both the space requirement and the outlay on equipment.
- the arm is formed from a base section and an end section, that the base section is connected at one end to the holder rotatably mounted on the base so that it can pivot about a first pivot axis, wherein the pivot axis of the base portion is transverse to the axis of rotation of the holder that one end of the end portion about a second pivot axis with the other end of the
- Base section is pivotally connected, that the first and the second pivot axis and parallel to each other, that the end portion of the arm carries at its free end a head unit about two normal axes and rotatably mounted, on which a hook-shaped gripping element and one the beginning end of the wire coil directing clamping device are arranged, and that control units are provided for pivoting or rotating the holder, the arm sections and the head unit.
- the clamping device By dividing the arm into two sections according to the invention, the required space is considerably reduced both in the working position and in the ready position.
- the clamping device also fulfills a directional function here. The consequence of this is that, compared to the prior art, there is no need for a clamping device which merely serves to feed the start end of the wire to a straightening unit.
- the device is particularly suitable for wire diameters of 10 mm and above.
- the start end of the wire is pushed into a drawing machine by means of the device, but can also be fed to a sharpening unit upstream of this machine.
- the gripping element is pivotally supported on the head unit in a controlled manner. In this way, the detection and insertion of the wire element into the clamping device can be promoted.
- the rows of the pressure rollers are mounted adjustable relative to each other.
- individual pressure rollers of one row are mounted so as to be adjustable relative to pressure rollers of the other row.
- At least two pressure rollers arranged opposite one another are connected to a rotary drive.
- the invention provides that the rotary drive can be reversed in its direction of rotation. This makes it possible to operate two lines of wire drawing machines with only one device according to the invention, the device then working together with two coils, each sitting on a reel. The device expediently stands between the two lines.
- 1 is a side view of an embodiment of the device in the ready position
- Fig. 2 is a side view of an embodiment of the device in the working position
- FIGS. 1 and 2 show a plan view of the device according to FIGS. 1 and 2.
- the device has a base 1 on which a holder 2 is rotatably mounted.
- a piston-cylinder unit 3 is pivotally mounted on the base 1.
- the piston 4 of the piston-cylinder unit 3 is articulated to a shoulder 5 of the holder 2, so that a movement of the piston 4 leads to a rotation of the holder 2 with respect to the base 1.
- a base portion 6 of an arm is pivotally connected to the holder 2 about an axis 7.
- a piston-cylinder unit 8 is articulated on the one hand on the holder 2 and on the other hand on the base section 6.
- the base section 6 is essentially L-shaped.
- a substantially rectilinear end section 10 is connected to the end of the base section 6 via an axis 9.
- a piston-cylinder unit 11 is pivotally articulated on the one hand on the base section 6 and on the other hand on the end 12 of the end section 10 of the arm.
- the end section 10 carries a head unit 13, which is rotatable both about the axis 14 and about the axis 15. These two axes are normal to each other.
- a piston-cylinder unit 16 serves to rotate the head unit 13 about the axis 14.
- the piston-cylinder unit 16 is supported at one end on the end section 10 and at its other end on a lever 17.
- the head unit 13 carries a hook-shaped gripping element 18, which can be adjusted in its inclination to the head unit 13 by means of a piston-cylinder unit 19.
- the head unit 13 is provided with a clamping element in the form of pressure rollers 20, which are arranged in two mutually opposite rows and between them receive and continue a wire end fed by the gripping element. At least two opposing pressure rollers 20 are coupled to a rotary drive. The pressure rollers 20 are positioned and adjustable to direct the wire passed between them.
- the rotary drive is expediently reversible in its direction of rotation.
- the arm formed from the base section 6 and the end section 10 is extended by actuating the piston-cylinder units 8 and 11 such that the hook-shaped gripping element 18 opens the start end of one by corresponding rotations of the head unit 13 a reel 21 seated wire coils 22 detected.
- the gripping member 18 is then displaced so that the start end of the wire is inserted between the two rows of the pressure rollers 20 and directed and passed through them. This is followed by a rotation of the holder 2 into the position shown in broken lines in FIG. 3.
- the head unit 13 is positioned so that the straightened wire end held in it is pushed into the inlet of a wire drawing machine or transferred to a sharpening unit of the wire drawing system.
- the device is then returned to the position shown in Figure 1. Starting from coils sitting on separate reels, the device can operate two lines of drawing machines.
