Definitions

• This invention relates to a machine with an improved wire- engagement system for winding a wire from a rolling mill into a coil.
• the wire from a rolling mill has to be wound on commercial-weight coils, that are then individually bound by strapping and placed in storage .
• downstream of the wire stabilization cooling system there are usually two winding machines to which the wire is fed - alternately - using a diverter.
• the two winding machines therefore work alternately, i.e. while the coil is being created on one, on the other a completed coil is removed and taken to the binding station.
• Machines and plant of this type are for example described and illustrated in patent applications PCT WO2004/108314A, WO2004/108315A, WO2004/108316A, WO2004/108317A, WO2005/084843A, to which reference should be made, by way of example, if any general clarification is required regarding the technical field in question.
• Threading and fixing the head end of the wire directly to the spindle (sleeve) of the machine has the major disadvantage of requiring the machine to be stopped for a relatively long time when changing the dimensional characteristics of the product being worked, which involves adapting the seat of the wire head end.
• the purpose of this invention is to avoid the drawbacks in the prior art summarized above by creating a machine for winding a wire from a rolling mill into a coil, in which the system for threading and attaching the wire head end to the spindle does not cause lengthy stoppages of the machine, in the event of product changes, or the need to carry out maintenance work and/or replace parts.
• This objective is achieved by making the system for threading and attaching the wire head end structurally independent from the body of the spindle of the machine.
• FIG. 1 is a longitudinal section showing an example of the machine according to the invention in an operating position winding the wire onto the coil;
• FIG. 1 is a plan view of the machine in Figure 1 ;
• FIG. 3 is an enlarged cross-section detail of the cover module of the machine showing the seat for threading and attaching the wire head end to the module, at the beginning of the coil winding phase;
• Figure 4 is a detail like Figure 3, showing the cover module during the spindle separation phase, once the coil has been wound;
• FIG. 5 is cross-sections like Figure 1, showing the sequence for removing the cover module from the spindle to enable the coil formed to be removed from the top.
• the coil winding machine is shown in full as 10, and is structurally formed by a motorized spindle 11 that, in the example shown, rotates around a vertical axis 12, but that could also rotate around a horizontal axis.
• the spindle 11 is closed at the top by a cover module 13, which can be moved using a movement structure 14 cooperating with the spindle 11.
• the structure 14 is made up of a base 15 bearing a track 16 on which a frame 17 is controlled by a motor 18 to move forwards and backwards in the directions of the arrow 19.
• the rear of track 16 is connected pivotally at 20 to a pair of lateral supporting pillars 21, while the front is connected pivotally at 22 to a pair of lateral hydraulic actuators (cylinders) 23, in turn connected pivotally at 24 to the base 15.
• the track 16-frame 17 combination can be commanded to pivot around 20, in the direction of the arrow 25, and the frame 17 to move - as mentioned above - in the directions of the arrow 19 ( Figures 1, 5, 6) .
• the rear of the cover module 13 according to the invention is supported on the frame 17 and is engaged (coupled) by rotation around the spindle 11, in an easily removable manner, for example by means of a self-centering jaw coupling, which may be of any type known to persons skilled in the art and is not illustrated in detail.
• said jaw coupling is schematized by a male element 26, connected axially to the spindle 11, and a matching female element 27, arranged centrally on the cover module 13, which rotates on bearings (not shown) inside a body 31 of said element 27.
• the cover module 13 is mounted on the free end of the frame 17, in a self-centering and pivoting manner, using pairs of arms 28. Said arms 28 are connected pivotally at one end, at 29, to the frame 17, and at the opposite end, at 30, to the body 31 of the bearings of the female element 27 of the joint connecting the cover module 13 to the spindle 11.
• the top of the cover module 13 is also linked to a pivoting disk 33 supported by the frame 17 by means of diametrically opposed pairs of hydraulic actuators (cylinders) 34.
• Said actuators 34 are connected pivotally at 35 to the frame 17 and at 36 to the disk 33 and they cooperate with underlying elastic pins 32 of the cover module 13, acting on the uppermost coils of the wire 40 to prevent any hindrance when removing the cover module 13 from the spindle 11 ( Figure 4) .
• a mobile vane 37 of a threading unit which in turn cooperates with a corresponding opposing annular collar 38, cooperates with the spindle in a known manner, extending from beneath the cover module 13, such as to define an annular seat 39 for threading and binding the first coil of the wire 40 coming from the rolling mill.
• the binding or locking of the wire head end 40 in the seat 39 may be effected by any known means, for example by wedging and fixing the wire head end 40 between angled wedge-shaped walls or surfaces 41, 42.
• surface 41 is the underside of the cover module 13, while surface 42 is the internal surface of the annular collar 38 that forms an acute angle with surface 41.
• the wire head end 40 is moved by the mobile vane 37 in the directions of the arrow F, to be threaded and locked by friction between the surfaces 41, 42 in the seat 30, after which the vane 37, in a known manner, leaves the spindle 11, such as to allow the winding of the coils of the wire 40, as shown in Figure 4.
• the operation used to thread the wire head end 40 using the mobile vane 37 is of a type known to persons skilled in the art and is not described here in greater detail.
• the operation of the coil winding machine according to the invention is clear from the above description with reference to the drawings, and can be summarized as follows.
• the coil is created with the machine in the position shown in Figure 1, i.e. with the spindle 11 closed at the top by the cover module 13, and with the vane 37 removed from the sleeve of the spindle 11 ( Figure 4) .
• the coil M formed may be removed from the spindle using known systems, after which using operations inverse to the aforementioned operations, the cover module 13 is repositioned on the spindle 11 for a new coil formation cycle.
• section of said wire may be circular (as shown by means of a non-limiting example) or a different shape, such as flat or angled or otherwise.
