Abstract

An auxiliary spool coaxial with the spool to be changed has its own drive and can be axially displaced, after having wound wire for a time sufficient to allow replacement of the other spool without stopping the machine, to allow the wire to be wound on a replacement spool. Appts is esp. useful in wire lacquering installations.

Description

Device for spooling on wire wokel machines - in particular In wire enamelling systems Dio invention offered a bobbin changing device Single or multi-thread winding in processing plants for wire or wire-like goods - especially in wire enamelling systems -, with an additional Auxiliary coil, where the coil is changed during the continuous operation is carried out.

When processing wires or similar elongated bodies, As with isolating, tinning, wrapping odor the like., The good is by means of appropriate Devices, for example in winding machines, wound on ready-made bobbins; here the winding speed depends on the working speed with which the processing in question can be performed and it will in general through to the working machine appropriate, in their speed controllable trigger organs determined. With the progressive improvement of the various Working process, the raw materials used - for example, the insulating materials, like wire enamels - and especially the processing machines are now increasing the necessary winding speeds of the wires. For example, when insulating thin copper wires with lacquer or similar substances few years with winding speeds of 30 to 80 m / min. worked; against it are currently speeds of several 100 depending on the wire diameter m / min.

common.

At such high winding speeds, however, the change in Finished winding by hand is no longer carried out without disrupting the work process which is why various facilities have been developed, in particular for small wire diameters to make it easier to change bobbins: particularly proven have on the one hand driven via adjustable clutches to a central Axis swiveling universal coils and on the other hand also arranged one above the other, unguided Interchangeable tapes with swiveling installation or help rolls; Fine wire is common also with suction air or compressed air in tubes from the finished coil to a Empty spool turned over, the working speed of the wire by pressure rollers is maintained on the Abaugeorgan. In all of these known processes is done by means of a loo stick applied to the looser pulse - e.g. by means of an um the bobbin of wrapped tape - the enemy held for the first handling, the separation of the wire between the Coiling can then be done by tearing or cutting.

However, this simple method fails when winding stronger wires, The adhesive on the coil core means that it is no longer sufficient for the first turn can be held; with Kuptr enamelled wire this is already around 0.20 mm Diameter of the case.

A bobbin changing device is now to be created at their use on both single-pass and multi-pass wire processing systems regardless of the wire diameter at any winding speed that occurs in practice a trouble-free implementation of the bobbin change is guaranteed - and the same if necessary, can also be carried out automatically.

According to the invention, this is the case with bobbin changing devices initially described type in an advantageous manner achieved in that the additional, hollow auxiliary coil, which is arranged coaxially to the finished coil to be replaced and overlaps a flange of the same, by means of its own An @@@ icbes independent of this finished pulse with a precedence over the running speed of the wire is driven and has an adjustable winding tension in a known manner, and that this tIilfsspulc can optionally be axially offset - i.e.

after it has been wrapped by folding the wire until the already full finished bobbin against a blank replaced and the continuously running wire was put back on this new spool. Appropriately, the core of this auxiliary coil should be so narrow that it is already Cross over the first applied turns of wire. The auxiliary coil can be on your Drive to be fastened interchangeably.

In a preferred embodiment of this Spulanwschsol device is the additional auxiliary coil with its drive and the winding tension setting also displaceable transversely to its axial direction, which means, for example, in multi-thread Wind a whole series of ready-made bobbins using a single auxiliary bobbin can be replaced one after the other.

On the bobbin changing device is another organ for cutting through of the wire after the respective superior of the same from the finished spool to the Auxiliary coil or vice versa installed, which either in a certain work phase can be operated manually or automatically by a trigger.

Finally, contacts can also be present, by means of which after a single programmer or all of them required when changing bobbins Operations can be initiated automatically.

The bobbin changing device according to the invention can therefore be used for both single-course as well as multi-course wraps - independently whether the finished coil in question is arranged with horizontal or vertical waxes is; the device can also be used in the same way for such wraps, in which the laying of the wire on the finished spool by means of a back and forth moved here Guide link - for example with a laying role -done and also for winding with a stationary opposite a Wire guide link reciprocated ferti bule. At wraps with vertical arranged ready-made bobbin can either the bobbin changing device according to the invention übar dor the coil or under the same. A decisive advantage This bobbin changing device consists in the fact that in the winding room for each wire run only a single ready-made spool with the associated drive and coupling elements must be attached - and not two ready-made coils as in the previous arrangements per wire path.

In the drawing are three exemplary embodiments of the invention Illustrated spool changing device on wire winding machines. It shows Fig. 1 and 2 a multi-pass winding machine of a wire enamelling system with horizontal plugged-on, reciprocating ready-made bobbins and one that is fixed in place Laying roll, with a bobbin changing device - in plan view or in front view, namely in different working phases of the Spulenwechselael device; Fig. 3 that Drive system dar associated auxiliary coil - in side view; Figures 4 and 5 one Winding-up, in which the finished bobbins are stationary with their drive and the wire feeder - FUhror are movably arranged - in side view or in front view; and finally Fig. 6, a winding frame with valuable items inserted ready-made spool and under the spool plate arranged bobbin changing device.

Let the winding of a wire processing machine shown in FIGS. 1 and 2 - e.g. a wire enamelling system - the eight-course winding frame will be the eight Wires D fed through the trigger device at an adjustable speed and over the deflecting rollers 2 and 3 as well as the usrlegerrolle 4 on the back and ready-made bobbins attached to the movable carriage 5 together with its drive motor 6 7 wound up. As usual, the drive of the finished bobbins takes place in relation to the wire speed with lead and with a winding tension that can be adjusted via a coupling or the like. At both Long sides of the winding frame is now a bobbin changing device that can be moved on rails 8 A or A ', which consists of the drive unit 9 and the auxiliary coil 10 and in turn are mounted axially displaceably together on the chassis 11; The auxiliary coil 10 is also driven with lead and adjustable winding tension.

The auxiliary coil 10 itself is hollow and engages over the flange the fertiqepule 7 as well as the shaft 12 above the same above the mounting elements for the coils (see Fig. 3).

To on the same winding frame finished bobbins 7 with different Use flange diameters and different lengths or different laying widths To be able to, the auxiliary coil 10 is arranged to be exchangeable; further is through the correspondingly variable, axial advance of the Spulenuiechsel device 9-10 which are different. Length of the finished coils taken into account, each of the form in Fig. 1 at Sides of the winding frame lleu drawn in bobbin changing devices A or A ' is - as can be seen - in a different work phase. In Fig. 2 is now the bobbin changing Device 9-10 in their actual working position illustrated with auxiliary reel 10 already lifted onto the flange of the finished reel 7 - So according to Fig. 1, above t By advancing the deflection roller 5 and laying roller 4 parallel to the finished coil 7 in the position 3 'and 4' is the wire D of the Finished bobbin 7 is placed on the auxiliary bobbin 10 and crossed in the groove profile the same with the first turns. After separating the wire D between the Fertibuls 7 and the help pulse 10 - with their drive motor 6 switched off at the same time can be - the auxiliary coil 10 with its drive unit 9 on its chassis 11 slightly retracted in the axial direction and - as Fig. 3 shows - move to the side, so that the finished bobbin 7 is completely frsi during the bobbin change operation is accessible - and thus the bsnachbarte finished coil 7 in its laying movement is not affected. After the bobbin change has been carried out, the following are analogous the two working phases described above are repeated cyclically.

FIGS. 4 and 5 now show a multiple frame of a wire winding machine, in which the ready-made bobbins lying horizontally at the same time in a different way are set as in the first mentioned embodiment (Fig. 1 and 2). the Wires D coming from the processing machine are fed over the pulleys 13 and 14, which determines the withdrawal speed, angstriebanan via a control gear Pull-off disks 15 pull and from there over the laying rollers 16 - which here be moved back and forth parallel to the finished bobbin 17 - aur the finished bobbins 17 relocated; the deflection of the laying rollers 16 - that is of the Position 16 'to 16 "- corresponds to the length of the finished bobbin used 17 (Figure 5). After the finished coil 17 is complete, the auxiliary coil is now 18 of the movable bobbin changing device A brought up and then by pulling it out dor serving rolls 16 in the position 16111 indicated on the outside left of the wire 0 this auxiliary coil 18 turned over - with the normal laying movement 16 'at the same time - 15 "is switched off; after cutting the wire D between the Fortig coil 17 and auxiliary coil 18 and pulling back the latter, the device becomes sideways moved and the bobbin change - as described above - carried out. With the repatriation the auxiliary coil 18, the overlay of the wire so D by engaging the traversing roller 16 from the position 16 '' 'to the movement 16' - 16 "and with the dom crossing the first turns on the finished Spain 17 - possibly with an auxiliary groove on the core same - the wire between the auxiliary spool and the finished spool can be cut again and the device is cleared and moved for the next change.

Mahrgänglge wire winding frame with vertically inserted ready-made spools can certainly with the coil mechool device according to the invention in analogy Equipped in the same way, just for Mickkelgestolle with herizontslen Finished bobbins.

In this case, only the auxiliary coil with its drive, the Winding tension adjustment of the sewing and guiding blioders coaxially to the finished coils be arranged over the same.

fig. 6 zoigt a Spulonmechsol device for winding sets with Ready-made bobbins placed on original Achson, such as those in particular for scgenannts wide delivery packages for high wire weights - for example with Kenischom Skpulankenvordendket been. The finished bobbin 19 is placed here on a bobbin plate 20 and with centers the cone 21; the drive takes place at the bottom by the angoordnotu drive unit 22 again with lead and adjustable winding tension. The wire D is from the trigger The working machine is fed via the unlank roller 24 to the retainer roller 25.

The auxiliary spool 26 of the Spullenwochsel device is located below the Spviontollor 20 with its drive unit 27 - what gloichfells with pre-oiling and a single cell Winding train will engetricben. This auxiliary bobbin 26 is used when the bobbin winder is replaced 20 for changing to Dineenders Spulennbenzen also with aus@ochealber.Beim Demickelß the finished coil 10 is the Vericgerrollo 25 parallel zer coil axis between the upper limit position and the lower 25 'moved back and forth and to the überlsgo @ of the wire D on the auxiliary spool 26 is then the shift roller 25 in brought their outer position 25 "- so both processes are completely analogous to the horizontal Arrangement; after cutting the wire between the finished coil 19 and the auxiliary coil 26, Spulenwechseleal and reserves of the Drchtes D with the feed roll 25 in the Dewbewegungesrecks 25'-25 socic finally after another separation of the wire from the auxiliary coil 25, can diosolbe regardless of the winding of the fartig-Spuls 19 for the next Spelos @@ chssl from the remainder of the wire.

Finally, when using the bobbin changing device according to the invention In addition, the individual work phases carried out on wire winding machines A) The auxiliary coil - the core diameter of which is roughly equivalent to that of the fully wound Finished bobbin corresponds - with its drive, the finished bobbin is sprayed so far that that it just engages over the outer flange of the same, and switched on; wsiters the winding tension is set.

B) The rotation to be run up from the working machine is overlaid by the finished bobbin / - For example, by leading out the wire laying guide up to the auxiliary coil; the wire is extended on the finished reel by moving it back and forth of the wire installer, then this is at the same time with the leadership over the auxiliary coil switched off.

C) The wire is either made by hand between the finished and Hilts coil cut from or with a tool; a cutting device can be used for this purpose be installed in such a way that they are triggered by a trigger in the relevant work phase is actuated - so be it rach over the wire of the finished - coil on the Auxiliary coil or vice versa.

D) The auxiliary pulon aggregate is at most axially outwards and towards the Move side - to easily replace the fully wound ready-made bobbin with an empty one.

E) The Fortig-Spulo is exchanged and then the Rllfespulen-Aggregat wisder brought back to its display mis under A) described n /.

F) By leading the twist looser leader back over the finished reel the wire is laid over the same - and at most the laying movement switched on again.

£) After crossing the first wire layers on the core of the finished coil the wire is cut again in the same way - as above under C) described.

H) At most, drive and remove the auxiliary coil unit Wire from the auxiliary spool by cutting - eventusll automatically; diosor so The resulting wire waste is - on the one hand, when the whole thing is carried out quickly Work process and on the other hand with the endeavor to use as large as possible Ready-made spools - quite portable or negligible.

The bobbin changing device according to the invention for wire winding machines can be used for semi-automatic or fully automatic with appropriate additional equipment Course of the individual work phases or the entire work schedule trained be - with the respective triggering, for example, by a at a certain Winding diameter of the finished bobbin actuated trigger takes place.
