and other components all rotating at high speeds. Such Vibration easily prevents precise regulation of the winding. It also indirectly limits the speed or the amount of product discharge.

In order to be able to handle wire of different diameters and to be able to form bundles of varying diameters it is necessary in conventional machines, further rotating parts in the already complicated structure To use arrangement, but this leads to even more vibrations. In addition, the number of with Usual units achievable changes in operation exactly limited; this must be done in an extensive manner Parts of the work arrangement need to be replaced. In order to even define the mold axis or the POorn for a common unit in Changing one of different diameter must be done carefully and precisely, and especially Selected chucks are used, as this is necessary due to space limitations. To the machine then Switching from one AND quantity to the other is common a considerable time and not insignificant '. EA can be required to view the individual parts of the machine adjust again to each other and the forming rollers to the Adjust the expanding mandrel and align it with it.

During the winding up of the bundles, regulation of the tensioning work rolls or of the winding rolls with respect to the forming axis, which is arranged between them, is absolutely necessary « Construction. However, this again exposes the machine to further vibration risks. BAuI: "On the usual machines, however, very stiff and very compact construction, in order to reduce these vibrations * the sensitivity of the control is also reduced. On the other hand, attempts to make the customary winding machines more versatile also lead to considerably reduced stability against vibrations.

The object of the invention is therefore to produce a wire winding machine with excellent balance and smooth workflow, the machine being particularly suitable for hon · working speeds and thus for high product quantities with increased uniformity of the bundles flhlg «should.

According to the invention, this advantage as well as that continues The advantages listed below are achieved by a rotatably driven spindle on an axis at one end of the Spindle sum drive through this receiving chuck; • in pairs of rotatable on the extended axis of the

Chuck for spreading a shaft in rollers arranged in the hitter; Bearings for the winding rollers; as well as by a Pair of speed-reducing take-off devices from both sides of the spindle for driving chucks and indirect drive of the winding rollers.

Due to the special arrangement of the individual parts in the winding machine according to the invention and the related drive only one rotating member driving the mandrel rotates at high speed; and this Element is firmly anchored and in its construction, in order to achieve an extensive reduction in vibration, been balanced.

The winding machine according to the invention also has relatively simple individual parts that are balanced and arranged symmetrically and thus ensure smooth, smooth operation, while simple switching from one wire dimension to the other from one coil diameter to the other remains possible can also be done in a matter of minutes by simply replacing a few parts . This replacement is done in a simple, quick and convenient manner by loosening and pulling out a pair of components and inserting and bracing others.

The invention is also directed to a winding machine ■ with a drive structure that leaves enough space between the leaves both drive trains for the forming rollers, whereby the use of the well-known, partially actuated "Jakobs * Chuck for releasable recording and for holding the Form axis or the mandrel is possible. The axis can therefore be changed quickly and easily.

The invention is directed to a further feature to a winding machine that is able to adjust the winding roller speed over a wide range Area to be effected by simply exchanging a sleeve element »within a few

The wire winding machine according to the invention can advantageously also be a sensitive, precise, optional Transverse adjustment of the two winding rollers symmetrically to the winding axis by simply adjusting the control knob enable.

In addition, the invention is directed to a winding machine with a fully balanced and rigid symmetrical construction that provides optimum control and. Versatility of the spreading parts on both sides of the Form axis enables · Each winding roller can be axially independent or together with the other winding roller and

of the axis. The reels can be inside can be moved across a wide range across the shaft, and can assume different mandrel diameters. she can also be moved at an angle to the axis at the same time. Each of these movements is done with high Sensitivity, great accuracy and independence from the others.

So the machine is extremely versatile. It works particularly sensitively in the zone of the axis, but always under soft, balanced or balanced and praltisch vibration-free operation, even at extremely high working speeds.

The invention is also directed to a wire winding machine in which the Arbeltswalzen at an angle to the forming Born does an imaginary transverse axis that can be pivoted through the centers of both the work rolls and the center of the dome runs to maximum alignment when Winding up between them regardless of the angular position of the work rolls to each other and to achieve the mandrel.

The winding machine according to the invention is also special except for the main spindle driving the mandrel Uniform drive without gears and without individual parts can be carried out at high speed.

According to the drawings, the entire winding arrangement is OK applied to a support base 12, which has a housing with a suitable electric motor 11 and a V-belt drive 13 (Fig. 3), which the pulleys 16 and 18 (Figure 2) drives. The base includes an upper stage 14 which contains the main working elements of the winding machine wearing.

909884/0498

The centrally arranged spindle 20 with high speed drive, which is driven by pulleys 16 and 18 firmly connected to it «extends Im substantially over the entire length of the device of front to back, and then supports the mandrel chuck 36 (Fig. 2, 3 and 15) on the front lap delivery end and a friction drive sleeve 22 on the opposite rear end (Fig. 2). The spindle is in bearings rotatably mounted in vertical front and rear walls 24 and 26 of a rigid, vertical, box-shaped carrier are arranged, which also comprises side walls 28 and 30. These 4 flat walls made of Steel plates extend vertically and are joined together at their edges to form a central rigid beam attached to the platform 14 of the base. All powered working elements of the assembly are driven directly or indirectly by the spindle. The 3 main elements that are powered must are (1) the high speed "Jacobs" chuck 36 (Figure 15) which is attached directly to the face of the spindle and contains the take-up shaft 64 (Fig. 15) on which the wire is wound, and (2) against the shaft expanded work rolls 60 and 62.

The work rollers are indirect from the friction drive sleeve 22 (Fig. 2) on the opposite rear end

909884/0498

the spindle 20, i.e. driven by the spindle 20 driven sleeve 22 drives the friction rollers 40 and 42 in frictional engagement therewith. The diameter only matters a fraction of that of the friction rollers to get an immediate speed reduction? These friction rollers in turn drive two flexible drive shafts 44 and 46 (Fig. 6) which extend forwardly in the box-shaped support. At the front End of the drive shafts are toothed, timed pulley wheels 48 and 50 (Fig. 13) arranged to drive the respective belts 52 and 54 which extend inwardly and around the larger rear pulleys 56 and 58 which drive the work or form orphans 60 and 62. A second speed reduction takes place between the pulley gears smaller and larger diameters. The drive connection from the spindle 20 via the sleeve 22 to the Friction roller 40 and 42 is shown in detail in Figures 2, 6, 7 and 5. The details of construction thereof Individual parts are shown in more detail below.

The rear end of the spindle 20 includes a connected, tensionable slotted coupling 70 and a rearwardly reaching shaft journal of smaller diameter 72. A dimensioned drive collar 22 made of metal slides over the lug 72 and is on the spindle 20 for the purpose of stopping

909884/0498

by introducing the neck portion 22 'of smaller diameter into the slotted collar coupling 70 and tightening

of screws 71 and 73 (Allen screws). the Sleeve 22 can be replaced by other sleeves of different diameter in order to obtain a predetermined drive reduction. The friction roller can In the Did the spindle pin rather than grasp the sleeve.

These friction rollers 40 and 42 include tires 80 and 82 (Fig. 2) made of rubber or the like, which are mounted on rims 88 and 90, which are integral with the axle hubs 84 and 86 connected. These hubs sit for rotation on hollow sleeves 94 and 96, which at their front end with standing: \ connective links98 and 100 (Fig. 5 and 6) are attached. As the spindle 20, clutch 70 and friction drive sleeve 22 rotate, the two Friction rollers 40 and 42 rotated around the axle sleeves 94 and 96 with their hubs 84 and 86 supported. These friction rollers are not directly connected to the flexible drive shafts 44 and 46. Are the flexible drive shafts 44 and 46 supported by the connecting links 98 and 100, through the axial sleeves 94 and 96 and through the friction rollers 40 and 42 extend and protrude rearwardly beyond them, rotatable and axially displaceable with respect to all of these elements. The rotary drive connection with the drive shafts 44 and 46 takes place via

909884/0498

a pair of circular drive pulleys 110 and 112 (FIGS. 1 and 6} rotatably and axially attached to the rear protruding ends of drive shafts 44 and 46 by cap screws 114 and 116 (FIG. 6). A plurality of pins 118 and 120, for example plastic-coated "Allen" - * bolts 118 and 120 extend through collars 110 and 112 and are in threaded engagement with the back sides of the friction rollers 40 and 42. the coils 110 and 112 are axially in a position on this rigid pins to slide and allow axial occupancy of drive shafts 44 and 46 with respect to the rollers, however, do not rotate relative to them, so that when the sleeve 22 rotates the rollers 40 and 42, these pins 118 and 120 cause the collars 110 and 112 to rotate which in turn rotates the flexible drive shafts 44 and 46. Axial adjustment is important to allow the slide plate adjustment fore and aft as will be discussed below.

As previously mentioned, rollers 40 and 42 are rotatably connected to the upper ends of similar vertical links 98 and 100. The stationary connection pieces are pivotally mounted at their lower ends to a horizontal, fixed in the transverse direction of the carrier 120 which is fixed against the base of the box-shaped support or base and, in particular against the wall 24th the

909884/0498

Intermediate portions of these links 98 and 100 are interconnected by one setting, the shafts with counter threads 122 and 124, which are connected via a central collar 126. The two threaded sections and 124 range with their opposite right and Left-hand threaded by a pair of pivot pins 130 and 132 which in turn are threaded by links 98 and parallel to the pivot axes of the connecting links · When turning the control knob 134 at one end of the threaded adjusting device, both rollers are moved transversely away from the spindle drive 22 at the same time or moved towards it with an oscillating, arc-shaped movement. Since the two drive shafts 44 and 46 are flexible, this setting does not affect the components at the front end of the machine.

As previously mentioned, drive shafts 44 and 46 drive the toothed timing belts Toothed lock washers 48 and 50. In particular, the front ends of drive shafts 44 and 46 are in the rear ends 45 and 47 with reduced dimensions of the collars 53 and (Fig. 13 and 15) set. These cuffs own forward Reaching shafts 49 and 51, which extend through special suspensions 150 and 152 and are rotatably supported by these. On the ends of the shafts 49 and 51 in front of the Suspensions are arranged gear pulleys 48 and 50 «These drive cylindrical work rolls 60 and

62 over the V-belts 52, 54 and the toothed belt pulleys 56 and 58 "with the buoy on the axles 17O and 171 of the work rolls is attached. These axes 170 and HI are also rotatably arranged on suspension rails 150 and 152. The work rolls are stored in a special heat, which means that adjustment movements ■ with high sensitivity can be precisely and closely controlled

The mounting of the work rolls 60 and 62 is shown in FIGS Fig. ΙΟ »11, 12, 15 and 3 shown. The work rolls 6p and 62 are rotatably mounted on suspensions 150 and 152, respectively, which in turn are pivotable on sectors 154 and 156 are provided and adjustable along an arc on forward and backward movable slide plates 158 and 160 (Figs. 8 and 9). the Balden suspensions 150 and 152 are mirror-inverted elements, just like the two Sectors 154 and 156, while the two slide plates 158 and 160 are essentially identical. Mr the description is enough to consider only one. Suspension and a sector.

The suspension 150 is shown in perspective in FIG. 11. It is suspended on an axial shaft 166 which extends beyond it in front and behind and parallel to the

909884/0498

The axis of the work roll 60 from which it is suspended runs * The work roll is attached to the lower end of the suspension 2150 (FIG. 12) on a rotating shaft 170 extending backwards. The sector is arcuately movable in its plane, parallel to the axis of the pin 166 and the shaft 170. This movement is indicated by arrows in FIG. The arc movement is made possible by bolts and slot connections between each of the sectors and the corresponding slide plates.

In particular, the sector 154 is attached to the slide plate 158 by a pair of bolt connections 180 and 182 that extend through the sector and through the corresponding archers 184 and 186 in the slide plate 158. These archers have radii of equal size, the center of generation of which extends on a line 190 which runs transversely to the device (FIGS. 12 and 15). This line, which serves as the focal point for the radii of the shooters in both sectors, is an imaginary transverse axis which runs directly through the centers of both work rolls 60 and 62 and through the center of the axis or shaft. It also includes the focal point of the radii of the domed slots 185 and 187 with the slide plate 160 (Fig. 1) through which bolt connections 181 and 183 extend for supporting the sector 156. It thus extends through these centers, although the work rolls are arched around yours

909884/0498

they are shifted to stocking sectors 154 and 156. This is important in order to maintain the waistband winding accuracy Maintain the versatility of the job.

The arching movement of the two sectors occurs simultaneously, one in an ear-wise direction and the other regulated counterclockwise or vice versa Movement of the sliding device herewith, which has an adjustment handle 200 contains moves. More precisely, on the spindle axis, in front of and in the vicinity of the wall 26 of the support box the vertically extending operating lever 200 (FIGS. 2 and 14) is pivotally mounted. Of the lower part has a pair of laterally oppositely extending fingers 202 and 204 with spherical Balls 206 and 208 attached to the front surfaces are · By the arcuate movement of the lever 200 around the spindle 20 (as indicated by arrows in FIG. 15) these balls optionally raised or lowered or vice versa and act on the sectors 154 and 156. The sectors 154 and 156 comprise a rear opening, elongated bearings 212 (FIG. 12) and 213 (FIG. 10), the the balls 206 and 208 (Fig. 10> 12 and 15) with a record relatively tight tolerance. Opposite vertical movement of fingers 202 and 204 creates an opposite directed vertical movement of the balls,

909884/0498

-I-

and an opposite arc displacement of sectors 154 and 156. A cover 430 (Fig. 3) is expediently arranged over the box-like support for the spindle and can be provided with markings 431 drawn on it to indicate the relative position of the arm 200 and thus the angular position of the Forming rollers

Any particular angular position of the device can be made by tightening the alien screw 220 (Fig. 4) which extends through the slot 222 in the lever 200 (Fig. 14) and in the front wall 26 (Fig. 2).

The mounting of the work roll 62 is essentially the same as that of 60 except for the mirror image configuration. That is, the rearwardly extending shaft 170 (FIG. 13) is rotatably attached to the lower end of the suspension 152. Axial journals 170 and 171 extend through the openings, ie the opening (FIGS. 11 and 12) in the suspensions. The suspension is mounted on sector 156 on a front-to-rear pivot shaft 167 parallel to the opposite shaft 166 on the other suspension. The sector is similarly arcuately attached to the slide plate (Fig. 9) via pins 181 and 183 which extend through arcuate slots 185 and 187 (Fig. 1) for securing the sector.

909884/0498

Since suspended 49 and 51 via suitable openings through the suspensions, the corresponding shafts, in the suspension that is, the aperture 59 150 (Figure 11) _e that is from the flexible drive shafts 44 and 46, affected an arcuate displacement of the suspensions over their pivot 166 and 167 do not reduce the stiffness of the regulating belts 52 and 54, since both drive pulleys - i.e. 48 and 56 on one suspension and SO and 58 on the other suspension are kept at the same distance. Rd achieved by pivoting suspensions 150 and 152 on the respective upper bearing journals »Since the work rolls are suspended on the lower parts of these suspensions * the work rolls move along an arcuate ©» BaIm In the same transverse plane. This setting is achieved and controlled by transverse control devices GFIg, 45 _t, which are composed of a pair of shaft parts 260 and 262 with counter-threading, which are connected via a flexible torsion spring 264, and which have a control button 266 and locking devices 268 on one end, ie on have the shaft part 262. Threaded shaft portions 260 and 261 extend through openings 263 and 265 (Figs. 4 and 11) in the hangers and are screwed into engagement therethrough. Since portions 260 and 262 have mating threads, ie, left and right hand threads

909884/0498

U99092

or vice versa, a turn of knob 266 (after Loosening the locking button 268) a movement of the suspensions 150 and 152 and thus the work rolls 60 and 62 towards and away from each other. The flexible spring 264 is counter-threaded between the parts provided so that one of the drive rollers is axially displaced with respect to the other (as shown in Fig. 13) can without affecting the cross ratio between the rolls would be affected.

The particular diameter of the work rolls 60 and 62 can be changed by removing the spacers 60 * and 62 * (Fig. 13) and replace with other work rolls on the hubs. To achieve this, the Rolls spread apart and the replacement made; then they will be back in working distance from Bring the mandrel together and set the mandrel and wire diameter.

An axial movement of the work rolls on their axes parallel to each other is achieved by forward and Moving one or both slide plates 158 and 160 backwards. As each work roll is attached to its own suspension is attached and each suspension is provided on its own sector and each sector in turn on its own sliding plate, allows a forward or backward movement of the

909884/0498

respective sliding plate these parts also move. The attachment of the slide plate 158 is shown in FIG. 8, the attachment of the slide plate 160 being substantially the same. Each slide plate is attached in guides at the top and bottom. In particular, as shown in Figure 8, the plate 158 has a box-shaped side wall 28 along its inner surface; a vertical mounting plate 300 along the lower edge and a smaller lower retainer plate 302 _# attached to plate 300 and enclosing a lower outer portion of slide plate 158; and an upper T-shaped retainer 306 extending along the top edge and the top outer surface of the slide plate 158. The other slide plate 160 has a similar support plate 300 * and upper and lower support plates 302 * and 306 * (Fig. 1). ■ -

Along the top edges of these two sliding plates 158 and 160 are cutouts in plate 158 and 312 in FIG Plate 160 is provided and have racks 314 and 316 each on. In engagement with each rack is a StJmzahnrad, e.g. the spur gear 318 (ELg. 8), for the Rack 314 is provided. It is connected to a shaft 320 that extends through plate 306 and has a Control button 322 on it. One turn of knob 322 therefore rotates the slide plate 158 forward or backward depending on the direction of rotation. In a similar way

. e>

9 0 98 84/0498

One rotation of a corresponding knob 324 (FIG. 2) moves the slide plate (160) forwards or backwards. The individual sliding plates can be locked in a specially adjusted position by tightening the locking buttons 330 or 334. As a result, the corresponding collars 336 (FIG. 8) or 338 (FIG. 2) are bound against one side of the arrangement and the corresponding retaining nut, for example the nut 340 (FIG. 8) against the opposite side of the arrangement, namely because of the Threaded pin part, for example 336 '(Fig. 8), which extends through this and receives the nut.

In use of the device, a magnifying glass 420 is usually on a support 422 (Fig. 2) above the well . arranged for precise monitoring of the vetch! process. In addition, the. Direction 150 (Figs. and 3) means a device for cutting the collar in the vicinity of the discharge end of the mandrel for cutting the collar C (Fig. 3) which is built up in segments.

During operation of the winding apparatus, the wire W - as shown in Figure 4 -. Ie, on the guide plate 470 below the guide disc 472, by an oil bath in the tank 474 and then upwardly around one of the Arbeite- rollers 62 out and into a Sund C are wound on the mandrel 64 while the mandrel dCeht and the

Work rolls 60 and 62 dtehen and wrap the wire around the mandrel and guide it from the free end of the mandrel. Optionally, the wire can be guided upwards through the guide openings in conventional guide plates (FIG. 4) and directly under the mandrel between the work rolls, as indicated by a dashed W "in FIG. 4.

The magnitude of the relative rotational movement of the mandrel with respect to the Arbeltswalzen 60 and 62 certain diameter and a mandrel with a certain 'diameter in adaptation to the desired Bünddurch- * knife optionally by selecting a drive sleeve certain diameter, working rolls and set the diameter of the related wire. The spindle 20 is driven at a selected high speed of a few thousand rpm by the usual electric motor via the usual V-belt drive via the pulley 16 and 18 (FIG. 2). This spindle is arranged very firmly so that no oscillation of any noticeable extent can be observed at high speeds. After selecting the appropriate sleeve 22 on the rear end of the spindle and attaching it, the relative positions of the friction rollers 40 and 42 for engagement with this sleeve are adjusted using the knob 134 (Fig. 5> to pivot the links 98 and 100).

The setting of the work rolls with respect to each other in

90988A / 0498

a transverse plane for adjustment to a certain wire size and the mandrel 64 is reached by turning the adjustment knob 266, whereby the two suspensions and the work rolls are pivoted inwards or outwards. The mandrel 64 of the desired size is inserted into the Jacobs chuck 36 in a very simple manner by loosening the chuck with a key in the usual way. One can use a Jacobs chuck on the winder of the present invention (for the first time) because of external and revolving spreader drives that use the friction drive from the center spindle, with flexible drive shafts spreading the assembly and regulating belts extending back into the work rolls. This leaves a lot of space for the Jacobs chuck. The selected forwards and backwards displaced position of the forming rollers is obtained by loosening the buttons 330 and / or 334 and by adjusting the spur gear knobs 322 and 324, whereby the side plates and thus the entire individual assemblies are displaced forwards or backwards. A floor movement of the work rolls in a pivoting position about an imaginary horizontal transverse axis 190 (e.g. FIG Work rollers can be moved to the desired angle .

909884/0498

The wire is then fed either around one of the work rolls or directly, as previously described, up to the mandrel so that it is continuously wound onto the mandrel by rotating movement of the mandrel and the two work rolls. Whose rotation ratio is preferably about 30: 1st The wire collar C is usually removed axially from the end of the mandrel and can be cut into segments by a cutting subassembly 450 (FIGS. 2 and 3).

extensive experiments with the device according to the invention have an extraordinary versatility, a vibration-free, smooth workflow, ability Working at particularly high speeds, structural stability, rigidity and strength on the receiving axis or shown on the mandrel, as well as an accuracy of the setting, precision of the workflow, what a represents a significant improvement over all known wire winding machines. There are no gears present, as the drive is carried out by friction and adjusting belts. The Jacobs chuck enables this to be done quickly simple replacement of the dome as required «. The interchangeability the drive sleeve can change the speed the ratio that can be quickly changed to accommodate a spine size replacement to allow for different collar diameters.

By simply pushing it in or out with sliding movement into a new bushing between the friction rollers and by simply replacing a different dome This can be dimensioned in a few minutes to optimal! Proportions and the corresponding winding speed. can be adjusted.

The girder for the only one moving at high speed rotating part, the spindle, and the heavy sliding plates and sector connections on the sliding plates allow both a stiff and heavy construction for reasons of stability. The whole machine is symmetrical Made for perfectly balanced operation. The suspended work rolls on the ones arranged above Suspensions allow a high sensitivity of the work roll setting, so that a particularly sensitive Addressing directly on the receiving axis is ensured, which is the point where the mechanism for collars the highest quality must be monitored particularly carefully. Many other advantages occur over the known institutions without a doubt. Of course, certain construction details within the given teachings can be changed. 3 in the construction according to the invention Obviously there are a number of novel features that are in a special way work together, but they are also used individually
