Spooling device for textile machines.

The invention relates to a winding device for textile machines, in which a textile yarn is wound onto a bobbin or the like, as is the case, for example, with spinning machines, Twisting machines or curling machines is the case.

The major disadvantage of previously common winding devices is that once a full bobbin has to be exchanged for an empty bobbin is done by hand and, on the other hand, the machine must be stopped for this purpose.

09850/0245

The invention aims to remedy this by means of a winding device, which by automatically exchanging a full reel for an empty reel, the monitoring of the Machines much easier. The invention solves this problem in that in a winding device of the initially mentioned type an arrangement is provided by means of which the yarn feed to a full bobbin can be carried out for so long until an empty bobbin is ready in the winding position and the yarn running to the full bobbin is between the two Coils is cut. This means that the yarn feed needs during the winding process, i.e. during the bobbin change not to be interrupted.

A "full bobbin" is to be understood as a bobbin that is on a coil for a certain period of time Has found winding point and by any suitable measuring device, such as by measuring the Spool diameter or measurement of the yarn passage or by measuring the time lapse as "full" became. In some machines, the winding advantage according to the invention can be used for individual winding positions, a measuring device for switching on the winding process is provided for each of these points, or it the winding devices can also be combined into groups, for example coupled with a time control, a full bobbin is removed, regardless of whether a certain amount of thread is wound or not.

It is expedient to make the separation easier of the yarn approaching the full bobbin kept the yarn under tension, preferably under briefly increased tension until the thread is cut.

109850/02 4

It has been found that when the Yarn between the full bobbin and the empty bobbin, the end of the thread running through so strongly to the empty bobbin can snap up that it is carried away by this and thus wound onto the empty spool can. Naturally, this is particularly effective if the yarn is already on the empty bobbin before being cut is present.

In a special embodiment of a winding device in a textile machine with a roller designed as a cup The main drive at a winding station, through which a take-up reel can be rotated, is an auxiliary roller drive intended for a full spool released by the main drive, which this full spool until it is cut of the yarn in that required for winding the yarn Direction of rotation further twisted. In order to tighten the yarn to a greater extent until it is cut, it is expedient the auxiliary roller drive is designed in such a way that it has the full spool with one opposite the main drive higher circumferential speed. The auxiliary roller drive is expediently on the back and forth running one Yarn guide opposite side of the winding station arranged, whereby the to the set by the auxiliary roller drive in rotation running full bobbin thread through the Spooling point can be passed under tension. This tensioned thread runs, for example, over the cup roll, so that the main drive still helps to feed the full bobbin from the winding point to the auxiliary roller drive. Preferably the storage of the bobbin at the winding point takes place in such a way that one is released after winding full spool due to its own weight on the auxiliary roller drive slides in. In particular, it is provided that the coil

/ 0245

is mounted in such a way that its axis is opposite to the vertical plane passing through the axis of the cup roll is offset to the side opposite the thread guide.

The auxiliary roller drive can consist of two roles, which take up the full bobbin and set it in rotation, with one of these two rollers lowered in relation to the other can be or both can be swiveled apart, so that after cutting the yarn the full The reel can be removed from the machine, for example by sliding it onto a conveyor belt or a chute, which leads to a collecting container.

In a winding device that is used in a double-sided textile machine with several winding units on each side of the machine is installed, each of these auxiliary roller drives is expediently between two opposite one another Spooling stations on both sides of the machine and can therefore operate both. Appropriately is for the auxiliary roller drive In this case, a reversible drive is provided, which when winding on the one Masöhinseite both rollers are set in rotation in one direction and when winding at the opposite winding point the Rolls twisted in the opposite direction. This makes it easier to wind up in batches or in groups the use of a conveyor running through the middle of the machine in the longitudinal direction, which carries the full bobbins carries away. In operation, a number of winding units are first used on one side of the machine for winding switched on and then the corresponding winding positions on the other side, the reversal of the auxiliary drives can be easily changed without reversing the original drive

achieve by each one roller of a roller pair of a drive group on one shaft and the other Rollers can be mounted on a parallel shaft. These two parallel waves are then optionally with corresponding Sprockets coupled through the opposite sides of a drive chain are driven, whereby, when the one roller shaft is engaged, it is rotated in one direction, and, when the parallel shaft is engaged, it rotates in the opposite direction. this means a significant simplification in the construction of such textile machines.

The cutting device arranged for cutting the yarn between an empty and a full bobbin can be formed in any way. In a particularly advantageous training, especially for the Automatic winding devices described above, this separating device for the yarn consists of an angled Plate with a "full" in the direction of the yarn Coil extending slot and a cutting device arranged under this slot. The actual cutting device is so under this slot that the full bobbin tapered yarn, which through the Yarn guide is passed into the slot, between the two cutting edges of the preferably designed as scissors Cutter arrives. The angled plate can also act as a guide for one of the normal Drive roller to the auxiliary roller drive released full Serve coil.

The empty bobbins are expediently stored in a magazine in the upper part of the machine and the magazine has it expediently with a mouth at each winding point Lips which hold an empty reel in such a way that it is gripped by a transfer mechanism and the reel holder can be fed to the winding station. This transmission mechanism is based on a special feature of the Invention of holding organs seated on swivel arms, which between the magazine mouth and the winding point are pivotable, these holding members and their pivot arms to release a coil apart and to Gripping a coil can be pressed against each other. In the case of a training, the two swiveling arrows are to be released a coil can be separated from one another in the axial direction and are available for gripping a coil by means of its holding members under spring pressure. In another embodiment, one of the two pivot arms is rigid and the other has one articulated forearm, which carries the corresponding holding member, so that by pivoting this forearm a Coil can be released or grasped.

A more detailed explanation of the invention emerges from the following description of some exemplary embodiments with reference to the accompanying drawings; show it:

FIG. 8 shows a drive arrangement with the same features as in FIGS. 5 to 7 »those in the Figures IA and IB machine shown is installed; and

Figure 9-11 details of this drive.

In the machine shown in Figures IA and IB it is a false twist machine, in the lower part of which coils 10 in a corresponding frame are arranged, of which a yarn, for example a synthetic yarn such as nylon, through feed rollers 10a a heater 11 and a false twist device 12 are fed, from where the yarn via feed rollers 11 is fed to a winding station in the upper part The machine is arranged and where the yarn is wound onto a bobbin or the like.

Such machines generally have a large number of false twist arrangements and, as a result, are located accordingly many winding units along each side of the machine, with the drive for the corresponding

■ f o 9 e :; o / o 2 4 ε

the parts, via drive shafts or via drive belts takes place from corresponding drive housings at one or both ends of the machine.

At each winding station there is a main drive, such as a cup roller 14, through which a bobbin 15, on which the yarn is to be wound, with a practically constant peripheral speed in Rotation is offset, reciprocating yarn guides 16 are provided which on a rod run back and forth, laying the thread evenly on the bobbin, making it go back and forth Movement can be controlled according to the winding shape to be produced.

At each of these winding positions is now the one according to the invention Arranged winding device, which facilitate the automatic winding in various ways should, i.e. the removal of a full bobbin from the winding position and replacement with an empty bobbin.

The most salient feature of the winding device according to the invention is that the winding process can be carried out without the yarn being fed to the individual Winding stations must be interrupted.

This is achieved in that the bobbin on which the yarn is to be wound can be rotated and released in this way is arranged in a holder that, when this holder releases the finished coil, the coil moves from the back and forth Moving yarn guide l6 removed and to an auxiliary roller drive gets, which keeps the full bobbin turning for so long

until an empty bobbin is in Contact with the cup roller 14 is fixed in the bobbin holder and the yarn between the full and the empty bobbin is cut so that the free end of yarn is immediately taken up by the empty bobbin.

In order to facilitate the delivery of the full bobbin from the thread guide 16 to the center of the machine, the axis of the Spool 15, on which the yarn is wound, from the vertical plane in which the axis of the cup roll 14 is offset towards the center of the machine. As a result, the full spool will roll as soon as it is released from the holder becomes, due to its own weight, to the center of the machine, at the same time in this direction due to its contact is advanced with the cup roll 14. In the The illustrated embodiment takes place the auxiliary roller drive at each winding unit by two rollers l8, which the two Use winding stations shown and the drive is designed such that when they open the winding station operate on one side of the machine, are driven opposite to the direction of rotation in which they are twisted to operate the other winding station. This is necessary because the corresponding full bobbins rotate in opposite directions to each other. aside from that these rollers 18 are arranged in such a way that they can be swiveled out into the fully marked position shown in FIG are so that a full spool fall onto the conveyor 19 and with this a receptacle or the like, can be supplied. For this purpose, these rollers 18 sit on shafts 20, which in the longitudinal direction run the machine and are mounted in angle levers 21, which by arms 22 on shafts 2? be pivoted can.

When falling from the winding position onto the auxiliary rollers 18, the full bobbin is guided through an angle plate 24, under which a separating device 25 is arranged for the yarn.

As can be seen from FIGS. 2-4, this separating device consists of two cutting edges 26 and 27, of which the one is fixed, while the other is rotatable. This rotatable cutting edge 26 has a protruding downward Approach 28 against which a pin 29 abuts on a rod 30 that can be moved back and forth in the longitudinal direction can, with this rod several winding stations on the. operated on one side of the machine. The separating device is on a holder 31 under a slot 32 in the angle plate 24 arranged. When a full spool 33 from the auxiliary rollers 18 is picked up and set in rotation and the yarn 34 runs from this bobbin to the cup roll l4, the yarn on the surface of the plate 24 through the Thread guide l6 guided back and forth until it enters the slot 32. As a result, the yarn 34 gets between the two cutting edges 26 and 27 * which now by turning the pivotable cutting edge 26 can cut off the yarn.

In order to cut the yarn 34 and take up the cut end by an empty spool 35 * which is pressed against the cup roller 14 to facilitate, the full bobbin 33 is preferably on the rollers l8 with a compared to the normal winding speed that you issued by the cup roller 14, rotated higher speed. This results in a short-term increased tension in the yarn 34, so that when severing the The free end of the yarn snaps against the empty bobbin 35 and is taken up by it.

The individual directions of rotation of the bobbins and rolls as well as the direction of the yarn are indicated by arrows in FIG indicated.

The holder, which holds the bobbin during the winding process, preferably forms part of the transmission mechanism, through which an empty bobbin is brought into the winding position.

For example, as shown in FIGS. 1A and 5 to 7, this coil holder has two arms 40 and 4l on a shaft 42 which is rotatable in such a way that holding members 43 at the ends of the arms 40 and 4l between a position in which it is arranged between spring lips 44 on the mouth of an empty spool magazine 45 Can take empty reel 47, and a winding point in contact with the cup roll 14 back and forth can pivot. The holding members 43 are on bearings 48 freely rotatable.

In order to be able to take hold of a coil in this embodiment and release it again, the arm 40 has a front part 40a, which via a pivot pin 49 with the main part is connected on the shaft 42 and is acted upon by a spring 50 in the direction of arrow 51 (Fig. 6). The forearm 40a has a rear extension 40b, which with a stop 52 on one in the longitudinal direction slidable rod 53 is engageable. If the rod 53, for example in the direction of arrow 54 (Fig. 6) is displaced, it presses against the end of the extension 40b and, as a result, pivots the forearm 40a against the direction of arrow 51, so that the

The coil 47 held between the holding members 43 is released Will. By moving the rod 53 in the opposite direction, the forearm is released again and can return to the position in which the holders 43 grip a spool 47.

In the embodiment shown, have the coil holder and the transmission mechanism also has a friction damper (Pig. 6 and 7) * around the vibrations to control a bobbin while it is being wound. as a freewheel assembly through which the arms around the Shaft 42 can swing around during winding, so that in the intermittent winding process a rotation of the shaft 42 all on her arms together in the Brings pickup position for picking up a bobbin.

For this reason, the arms 40, 4l are mounted on the shaft by bearings 80 (FIG. 7) and a third arm 8l sits firmly on the shaft between these two arms. The arm 8l has a circular arc-shaped end at the end Slot 82 through which a rod 38 is fastened with its ends in holders 40c and 4lc of the arms 40 and 4l is going through. This rod 83 carries friction elements 84 which work together with the end of the arm 8l, in which the slot 82 is formed.

When thread is wound onto bobbin 47, vibrate arms 40 and 41 around shaft 42 and irlf olgedessen, looking up at Figure 5, the rod moving along the slot 82. Since the arm 8l is fixed, the friction elements 84 prevent undesired vibrations of the arms 40, 4l and consequently also of the coils.

When changing the bobbin, i.e. after releasing the full bobbin, the shaft 42 is rotated around the arm 8l in a clockwise direction (Pig. 5), and when the lower end of the slot 82 contacts the rod 83, the Arms 40 and 4l twisted clockwise until their holder 43 has an empty reel between the magazine lips 44 align.

In another embodiment, the two swivel arms can be separated from one another as a whole in order to release a reel, and are compressed by a spring arrangement or the like to hold a spool between them. This can be achieved in that each arm has an elevation and the elevations interlocking Own thumb. One elevation is stuck on the rotatable shaft and the other is through one in the longitudinal direction slidable slide along the shaft against the action of a compression spring, which the thumbs against each other pushes, movable.

As mentioned earlier, each pair serves the auxiliary roles two winding units, and for this purpose the rollers 18 can be turned in any direction of rotation. When changing the bobbin on one side of the machine, for example, the rollers are rotated clockwise while they are in in the other direction of rotation if the bobbin is changed on the opposite side of the machine will.

An example of the roller drive is shown in Figures 8-11. Coaxial with the pivot pins of the toggle levers 21 (Fig. IA) two shafts 60 are provided, which extend over

i 0 9 Π "j * ι / 0245

extend the entire length of the machine. These waves can be at the drive end of the machine by appropriate Couplings 6l (Fig. 8) with corresponding drive wheels 62, 63 (Fig. 9), one of which with the outside. an endless drive chain 64 meshes while the other combs with the inside of the chain. This chain 64 also runs over guide wheels 65 and 66. By this training can be achieved in the simplest way that, when the chain 64 rotates continuously in one direction, the Sprocket 62 continuously in the opposite direction how the sprocket 63 is rotated. When changing the bobbin on one side of the machine, therefore, the sprocket 62 is coupled to its corresponding shaft 60, and both Shafts 60, which at the opposite end of the machine by a chain 65 (Fig. 11) and sprockets 68 frictionally are coupled rotate in one direction. However, when changing the bobbin on the other side of the machine occurs, the sprocket 63 is coupled to its shaft 60 and the shafts 60 rotate see in the opposite Direction of rotation.

Each shaft 60 carries a sprocket 69. The chain 64 is driven by the cam 70 for the yarn guides 16, which are guided back and forth on the yarn guide rod 17 by this cam disc via corresponding drivers 71 will. The cam disk 70, for its part, is set in rotation via an electric motor (not shown).

The cup rollers 14 sit on parallel shafts 72 which run in opposite directions via corresponding sprockets 73 (Fig. 10) are driven with the opposite Pages of a in closed circulation

jn / 0245

union chain 74 are engaged, which by the Main sprocket 75 is brought into circulation.

The sequence of the individual work steps during winding can expediently be controlled by a time control control, especially if the winding takes place in groups or in bursts.

In another embodiment, the bobbin is full as soon as it is held by the one holding it during the winding process Swivel arms is released, passed on to two auxiliary rollers, which during the bobbin change with one to 10 $ higher peripheral speed can be twisted than the cup roll receives, which briefly tensions the thread more tightly. After cutting the yarn, which takes place after an empty spool can pick up the severed end and is ready to start the winding process perform, one of the auxiliary rollers is lowered and thereby releases the full bobbin, which is then removed from the Machine is delivered.

The chronological sequence of the individual work steps when changing the bobbin is, for example, the following:

1. The auxiliary roles are set in motion,

2. Separation of the arms holding the coil for release the full bobbin on the auxiliary rollers,

J5. the yarn penetrates into the slot in the deflector plate and thereby lies in the cutting device,

4. The separated arms swing towards the mouth of the empty spool magazine and close around an empty reel,

09Γ

5. the arms carry the empty bobbin against the cup roll and bring it into contact with the one above it Cup roll of running yarn,

6. a stream of air is blown against the empty bobbin to force the yarn against it,

7. The yarn is cut between the full and empty bobbins and with the help of the blown air flow picked up by the empty reel, and.

8. The movable auxiliary roller is lowered to release the full bobbin and then into its starting position withdrawn.

Leave the individual work steps, which depend on how the previous work step was carried out switch on by actuating the corresponding limit switch.
