Abstract

A reeling-off device for steel wire reels the wire (29) upward and has a swivel (23, 19), which leads the wire downward through the centre of the wire coil (20) and out the side below the coil. On the upper portion of the wire coil a structure (21) is attached, which carries a ring with an outwardly directed bristle rim (26). The bristle rim constitutes a brake for the wire (29) and brakes the wire at sudden stops at the wire feed, so that the risk of knot formation in the wire is reduced. The device comprises also a balancing magazine (33-35), which forms a spring-loaded wire loop.

Description

A method of reeling-off wire from a wire coil and a reeling-off device for a wire coil.
Technical field of the invention
This invention relates to a reeling-off device for a wire coil and to a method of reeling- off wire from a wire coil.
Background of the invention and known state of art
Bales with paper pulp sheets are bound around with steel wire, which is reeled-off from a wire coil, and the reeling-offtakes place intermittently and at high speed. When the feed of the wire is stopped, the wire tends to continue to be reeled-off, so that there is risk of knot formation. In order to reduce this risk, a first wire guide usually is provided high above the wire coil, so that the wire can hang in a large arc. The risk, however, of knot formation and snarl on the wire is not eliminated thereby. The wire reeling-off station often is the station, which restricts the production speed of a production line.
Object and short description of the invention
It is an object of the invention to reduce the risk of knot formation and to allow for a compact reeling-off device. This object is achieved in principle in that the wire is drawn along a ring of bristle, which is coaxial with the wire coil. The bristle will then permanently brake the wire without impeding the reeling-off operation. The invention is defined in the attached claims.
Short description of the drawings
• Figure 1 is a lateral view of a reeling-off device shown as an embodiment of the invention.
• Figure 2 is a lateral view taken at a right angle to the lateral view shown in Figure 1.
• Figure 3 shows on an enlarged scale a detail shown in the preceding Figures.
• Figure 4 is a lateral view taken as indicated by the arrows 4-4 in Figure 3.
Description in detail of the embodiment shown
The reeling-off device shown in the Figures comprises a wheel-supported steel frame 11 with an upright wire coil stand consisting of four pipes 13-16, the tops of which are bent inward to and welded on a sleeve 17. A coil 20 with wire, usually steel wire, is threaded on the wire coil stand 13-16, and a conical pipe structure 21 with a plastic ring 22 rests on the upper portion of the wire coil 20. The sleeve 17 carries a swivel 23 and a pipe structure 24 with a ring 25. The swivel has an eccentrically located guide wheel 19, the horizontal axis of which extends perpendicularly to the vertical axis of the sleeve 17. The pipe structure 21 is conical, but has a straight portion 27 with a slightly smaller diameter than the inner diameter of the wire coil 20. The pipe structure 21 is inserted into the wire coil 20, so that its straight portion 27 is guided by the wire coil, and the conical portion 28 above the straight portion rests on the wire coil. The pipe structure 21 is thereby fixed in the wire coil, but can follow with the upper portion of the wire coil downward when the wire coil during the reeling-off operation gets shorter. The pipe structure 21 is prevented from turning, because the pipes 13-16 are located between four inward bent supports 38.
The plastic ring 22 is shown enlarged as the Figures 3 and 4. It has cast-in wires, which project out radially about its periphery as a rim of bristle 26. The wires are of a wear- resistant and flexible material, suitably a plastic like nylon, and their diameter should exceed 1 mm and can, for example, be 1-2 mm.Their projecting length can suitably be between 7 and 10 cm, and they can be arranged in one row as shown or in several rows. The plastic ring 22 is attached by screws to the pipe structure 21, and the ring of bristle 26 will always have one and the same position in relation to the upper end of the wire coil when the upper end is lowered during the reeling-off operation, because the pipe structure 21 rests on the wire coil, its conical portion 28 being located above the guiding straight portion 27. Due to this design, the wire cannot get clamped during the reeling- off operation.
The wire 29 from the coil is guided in an arc upward to the guide wheel 19 of the swivel 23 and down through the sleeve 17 and therethrough down through the wire coil to a guide roller 30 and over two more guide rollers 31 and 32 and up to a guide wheel 33 and over two guide wheels 34 and 35 to an outlet guide 36. The guide wheel 34 is movable and loaded by a tension spring 37, so that the guide wheels 33, 34, 35 together form the wire to a balancing loop, which reduces the accelerations at a sudden stop of the wire extraction out of the outlet guide 36. When the wire consumer, for example a binding station for bales, draws the wire 29 from the outlet guide 36 of the reeling-off device, the guide wheel 19 of the swivel 23 will follow along in the reeling-off of the wire, and the wire 29 will skid against the ring of bristle 26 as well as against the steel ring 25. The bristle ring 26 brakes continuously the wire 29, and this braking effect stops the reeling-off operation and prevents the formation of loose wire loops and, therefore, reduces the risk of knot formation. Together with the spring-loaded wire magazine 33,34,35, which implies that an instantaneous stop at the outlet 36 will not be equally sudden at the guide wheel 19 of the swivel 23, but slightly delayed in time, the risk of knot formation will be so small that it allows a much higher wire discharge speed and acceleration in a wire consumer, which consumes wire intermittently, for example a bale binding station. At the same time as the bristle ring constitutes a brake, which provides sufficient braking effect at sudden stops, it does not have a detrimental braking effect at the start. Too strong a braking effect at the start could cause wire fracture. The invention, therefore, renders possible better accessibility and increased wire feed speed.
