The invention relates to a wire rewinding or unwinding device for unwinding wire from an upright wire bundle held together by strapping bands located in vertical planes and for feeding the wire to at least one processing station such as a pulser and / or a wire feeder. or mesh welding machine, and optionally for the rewinding of the wire.

Bundles made of hot-rolled wire are increasingly in demand with higher bundle weights in order to make further processing more cost-effective. For smaller steel mills, which can produce only as a starting material for the wire billets up to a weight of 1750 kg, therefore, there is a need to weld either the billets or the wires of several wire coils together to be able to supply sufficiently large wire coils. In addition, increasingly higher yield strengths are required, which can be achieved by cold deformation of the wire. Also, it is necessary to rewind the wire by applying stretching and bending.

Both for the welding of the wire ends and for rewinding to increase the yield strength rewinding systems are required, which make much manual work necessary. The strapping tapes that hold the wire bundles must be cut and removed, and much crane and transport work is required. The beginning of the wire must always be searched for and properly inserted or threaded in reels or finishing equipment.

The invention aims to be able to automate all of this work to the finished salable large bundle that is strapped and labeled, or to a bunch or product differently processed wire.

The invention consists in a system of the type mentioned above in that it is characterized by a rotatable in both directions horizontal platform with a vertical, outwardly pivotable mandrel having mandrel, which platform can accommodate the wire harness in a vertical position, wherein the wire coil means a manipulator on the platform is lowered so that the mandrel is in the central opening of the wire waistband and the wire bundle in this position by means of a above the opening of the wire bundle einschwenkbaren and vertically movable pressure plate, which by pressing downwards the mandrel elements against the Contour of the opening pivots, can be fixed on the platform, and wherein a bandoling, cutting and -entferneinrichtung for the wire bundle comprising the vertical strapping bands is provided, which is externally approachable to the periphery of the covenant and while rotating the platform against the Abspulric by means of an electrical contact disposed on the band seeking, cutting and removing device, the strapping bands may feel in sequence, then cut and removed so that a wire end protrudes from the collar, and a wire-pulling and driving device engaging the protruding wire end is provided, which is movable horizontally and vertically and has movable against the wire end, rotatably driven drive wheels and can be approached to the located on the platform collar under the rotation in the wire withdrawal direction and by means disposed on the Drahteinzieh- and -dreibvorrichtung electrical contacts projecting from the federal government Detects wire end and retracts and supplies the at least one other wire processing station, where appropriate, the winding direction reversible and the processed wire is rewindable by means of the wire-winding unit.

Between the rotatable platform and the Drahteinzieh- and -reibvorrichtung advantageously an engagable to the federal pivotable lifting device for lifting the projecting from the wire end of the wire to the height of the wire end detecting electrical contacts of the movable Drahteinzieh- and driving device is provided.

In order to increase the yield strength of the wire, the wire preferably passes through a temper rolling stand immediately after it leaves the inventive winding or unwinding system.

A subsequent to two Drahtabspulanlagen invention wire processing equipment in a preferred embodiment, which serves to produce Drahtgroßbunden, claim 3 is apparent. This system can also be used in the case of the use of conventional coiler systems instead of the wire unwinding systems according to the invention.

Further, preferred features of the system for producing wire coils are found in the dependent of claim 3 claims 4 to 7.

The invention is explained in more detail with reference to an example shown in the drawings, in which the figures show the following: FIG. 1 a wire unwinding device without auxiliary devices explained below in a first phase in perspective view, FIG. 2 in a lower part of the system according to FIG 2 in the same view on a slightly larger scale and with a first auxiliary device; FIG. 3 shows the lower part shown in FIG. 2 without the auxiliary system shown in FIG. 2, but with a further ancillary system and a subsequent wire processing device in plan view, and FIG Fig. 4 to 7 schematically a subsequent to the wire processing system of Fig. 3 further Drahtbearbei processing plant for welding the ends of the two Drahtab-spulanlagen according to FIGS. 1 to 3 supplied wires to a single wire from the Drahtabspulanlage to a larger wire bundle is rewound in four consecutive work phases s.

The Drahtabspulanlage 1 shown in Fig. 1 without downstream auxiliary equipment used to unwind wire 2 from a wire collar 3, which is held together by arranged in vertical planes strapping 4. The wire bundle 3 in operation stands upright on a rotatable platform 5 in both directions of rotation, which carries a central vertical mandrel consisting of outwardly pivotable mandrel elements 6. The wire coil 3 has been lowered by means of a manipulator 7 on the platform 5, that the mandrel is located with the mandrel elements 6 in the central opening 8 of the wire bundle 3. More wire coils are available on a loading platform 9 ready to be brought by means of a gripper 10 in the position of the wire waistband 3 can. In Fig. 1 is a pressure plate 11 in a weggeschwenkten from the collar 3 position.

As shown in FIG. 2, the pressure plate 11 is pivotable above the opening 8 of the collar 3 and vertically movable so that it can pivot by pressure down the mandrel elements 6 outwardly against the contour of the collar opening 8. Thus, the collar 3 is fixed on the platform 5. The movement and

Swivel device for the pressure plate 11 is denoted by 12. In addition, FIG. 2 shows a banding, cutting and removal device 13 for the collar 3 comprising strapping bands 4 that can be moved to the circumference of the collar 3. By rotating the platform 5 against the unwinding direction, an electrical contact arranged on the device 13 can be obtained 14 feel the straps 4 in turn and then cut and remove them. Thereafter, a wire end 15 is from the collar 3, as shown in FIG. 3 can be seen.

Fig. 3 shows, moreover, an acting on the projecting wire end 15 Drahteinzieh- and-driving device 16 which is horizontally and vertically movable and movable against the wire end 15, rotatably driven drive wheels 17 has. The device 16 can be moved to the located on the platform 5 collar 3 with its rotation in the wire drawing direction and can determine the projecting from the collar 3 wire end 15 by means arranged at her electrical contacts 18 and feed and at least one other wire processing station. Between the rotatable platform 5 and the Drahteinzieh- and -reibeinrichtung 16 an adjustable to the collar 3 by pivoting lifting device 20 for lifting the protruding from the collar 3 wire end 15 to the height of the wire end 15 investigating electrical contacts 18, 19 is provided. 3, a wire processing station in the form of a temper rolling mill 21 detecting the wire end directly adjoins the wire drawing and driving device 16, which serves to strain harden the wire.

Another wire processing system is shown schematically in FIGS. 4-7 in successive different steps. Two juxtaposed stationary wire unwinding according to FIGS. 1-3 are here indicated in each case designated by 1.

According to FIG. 4, the wire 2 automatically pre-threaded from the upper wire unwinding device 1 is introduced by means of a gripper 23 with its end 15 between mutually movable clamping jaws 24 of a horizontally and vertically movable welding station 25 and held there. The expiring from the lower Drahtabspulanlage 1 2 wire is allowed to leak until its end 15 'arrives in the vertical plane of the end 15 of the upper wire 2. This is the situation of FIG. 5.

There, the wire end 15 'is held by a gripper 26, whereupon the welding station 25 moves with the wire end 15 held in it in the position of the wire end 15'. The wire end 15 'is then pressed between other mutually movable jaws 27 of the welding station 25 against the other wire end 15 and welded thereto. After welding the wires into a single wire, the rewinding process can be resumed by the upper wire unwinding unit. The wires 2 welded together into a single wire can then be picked up again by the upper wire unwinding lane 1. This is the situation shown in FIG. Here then the time span of the wire 2 from the lower wire 2 unwinding be exploited for 1, that the lower Drahtabspulanlage 1 charged with a new wire collar 3 and a new wire 2 'unwound from there and placed in a vertical plane in front of the welding station 25 in a waiting position ,

Fig. 7 shows the situation after the welding of the two wire ends 15, 15 'to form a single wire 2 and while it is rewound from the upper Drahtabspulanlage 1 into a larger coil. The welding station 25 is returned to its upper home position and can receive the end of the new wire 2 'between its jaws 24.

It then follows a new sequence according to FIGS. 4 to 7 with the only difference that the expired from the lower Drahtabspulanlage 1 2 'wire is first held in the welding station 25 and the wound up in the upper Drahtabspulanlage 1 completely runs out. For each of the emerging from the Drahtabspulanlage 1 wires 2, an electrical contact 28 for determining the wire end 15 and 15 'is provided.

Near the upper position of the welding station 25 and the lower gripper 26 each have a pair of scissors (29) is arranged. The lower shears 29 can be used to cut off a defective weld spot discovered by an automatic tester, for which an auxiliary gripper 30 is still provided.

Of course, with the wire processing system of Fig. 4 to 7, more than two wires welded together into a single wire and wound into a single, even larger covenant.

The Drahtabspulanlage according to FIGS. 1 to 3 can also be used without Drahtaufspulanlage for the case that the Drahtabspulanlage or the immediately subsequent Dres-sier rolling mill 21 another wire processing plant, such as a mesh welding machine, is arranged downstream.
