Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a winding device for winding a plurality of yarns continuously produced in a spinning device for chemical fibers.

<Prior art> The problem when operating this winding device is changing the bin. The problem is replacing the full tube bobbin with an empty tube. Conventionally, bobbin exchange is performed in steps 1 to 1 as follows. In other words, one or more threads can be captured within the range of the traverse motion triangle.
The thread is cut and taken out from the traverse device, and suction is carried out by a hand-operated suction gun.Then, the full bobbin is removed and an empty tube is inserted into the winding shaft.Then, the thread is guided to the thread preparation device below by the operation of the suction gun. The thread is attached to a thread mounting device, and the thread is partially wound around the empty tube in a direction opposite to the direction of rotation of the winding shaft. In this case, the thread setting device performs an axial movement. As a result, the thread reaches into a catch groove or other catch mechanism provided in the empty tube (cf. German Patent Application No. 25 47 401).
. In short, the operation of replacing the bobbin can be divided into manual operation of the thread and operation of replacing a full bobbin with an empty one. EP 26471 discloses an automatic device which separates the functions of manual thread handling and bobbin exchange. Such automatic devices are suitable for thread handling only if free exchange is allowed, i.e. the point of bin change depends on the throughput of the automatic device and not on the reverse winding state of each winding device. It can only be used when permitted.

In addition, a device for automating the start of the first spinning process, that is, the start of the spinning process and the winding process, is disclosed in Patent Application Publication No. 243 of the Federal Republic of Germany.
83 '64. This specification discloses a winding device in which two winding shafts that operate alternately are mounted on one common bobbin turret in order to realize dubbin exchange.

A loss-free bobbin exchange with a winding device of the above type with two winding shafts rotatably mounted on one winding turret is described, for example, in German Patent Application No. 32
It is disclosed in the specification of No. 11603. Such a winding device allows a fully automated bobbin change at any time. Bobbin changes are largely lossless and no debris is generated between bobbin changes.

However, the drawbacks of this type of winding device are:
Naturally, a winding device having two winding shafts is more expensive than a winding device having only one winding shaft. This disadvantage is only offset by the avoidance of waste yarn production and the avoidance of manual handling. Moreover, the avoidance of waste yarn production is especially important for thick yarns that require frequent bobbin changes, and the avoidance of manual handling is especially important when it is desired to carry out daytime and nighttime operations with minimal labor costs. It is.

<Problem of the Invention> The object of the present invention is not only to avoid excessive technical costs required for a winding device equipped with two winding shafts supported on a bobbin turret, but also to avoid manual operation when changing a bobbin. To provide a winding device with a low technical outlay, which enables the yarn to be manipulated without any problems, and which causes very little production loss of waste yarn when changing the bobbin, for example in the case of fine-grained yarn, and which, moreover, To make it possible to obtain the advantages of a winding device equipped with two winding shafts which are operated independently.

[Structure of the Invention] The solution to the above object is to use functional elements which are normally provided in the winding device and which are operated and partly manually guided when changing the bobbin, in particular a thread catcher, a thread cutter and a thread suction device. and thread setting device into a single device that is guided along a defined trajectory in an automated movement process.

The starting point in this case is that a plurality of .xi. cages (-pins) are formed on one winding shaft of the winding device. Therefore, each empty tube inserted into the winding shaft is associated with one thread suction device, one thread catcher, one thread cutter, and one thread mounting device.

Function> In the present invention, all functional elements for thread exchange include a thread catcher,
Thread cutter, thread suction device and thread attachment device are the only devices
It is integrated into the pointed suction nozzle of the b-thread suction device, which suction nozzle itself is guided along a defined movement trajectory in an automated movement process.

The motion process of the pointed suction nozzle is such that its motion trajectory starts from the yarn catching position, and the yarn catching position follows the triangle formed by the yarn during traverse movement (hereinafter referred to as the traverse motion triangle). It is located directly in front of the plane. Starting from this thread catching position, the trajectory of movement (projected onto the vertical plane of the winding shaft) partially encircles the winding device together with the traversing device and the winding shaft. In this case, it is advantageous for the yarn catching position to be located (viewed axially parallel to the winding axis) in the area of the edge of the traverse-traverse movement angle.

In addition to this motion component, the motion trajectory is synthesized from motion components parallel to the winding axis. As a result, the suction nozzle is guided laterally out of the range of movement of the yarn trapper and feeds the yarn on the one hand to the so-called system preparation device and on the other hand to the yarn catcher of the empty tube (generally a yarn catcher groove consisting of a circumferential slit). . In particular, the movement of the suction nozzle in the final part of the movement trajectory is a movement that is axially parallel to the winding axis and penetrates into the vertical plane of the yarn catch groove.

In order to clarify the concept of the technical terminology used in this specification, I would like to add that "bobbin exchange" in the above meaning refers to the period during which a full bobbin is replaced with an empty bobbin. It means the thread operation. In a broad sense, "bobbin replacement" must be understood as thread manipulation and the operation of replacing a full bobbin with an empty one. This exchange can be done manually. The automation of this changing operation is preferably carried out in particular by means of a docker that can run along the front of the machine and also by a known take-off device that pushes out the full bobbin from the winding shaft. For bobbin exchange, the receiving shaft of the docker is positioned in front of the winding shaft, and a pushing device provided in the winding device shifts the full bobbin or bobbins toward the receiving shaft. The empty tube is then inserted from the doffer onto the winding shaft using a suitable device. Corresponding devices are disclosed, for example, in DE 2939675 and DE 2945861.

In an advantageous embodiment, a guide tube for introducing air is connected to the spinning tube, and the starting point of the motion trajectory of the suction nozzle of the present invention is such that the yarn catching position for the first spinning is immediately in front of the guide tube. It is set to be located at

In one embodiment, the suction nozzle is mounted on a pivot arm, the pivot axis of which is located above the winding axis, viewed in the running direction of the thread. In this case, the movement locus of the suction nozzle draws a circular arc, and within the central angle of the circular arc, there is a
The soot device and the winding shaft with empty tubes to be operated are located there.

In this case, the pivot shaft can be arranged in the same machine part in which the winding shaft is located or in the same machine part in which the traversing device is located. In this case, the following points should be considered: ・In order to allow the traverse device to move backward relative to the winding shaft as the winding of the ξ cage becomes thicker, or conversely, to allow the winding shaft to retreat relative to the traverse device. Winding shaft and tiger
It must be possible to move relative to the grounding device.

In a further embodiment, the pivot axis of the pivot arm is located below the winding shaft, seen in the yarn running direction, and on the side of the truss motion triangle facing away from the winding device or on the side of the truss movement triangle. - It is placed on the plane side where the motion triangle is located. In this case, the swiveling arm is constructed as a telescopic tube, so that the movement trajectory of the suction nozzle consists of an axial movement component, an arcuate movement component, and a translational movement component.

In all of the above cases, the swivel arm is still movable axially parallel to the winding axis in order to obtain the said movement trajectory, and the suction nozzle is moved axially at the beginning and end of the yarn feeding movement for yarn loading. I do.

In a further embodiment, the functional element is supported on a support or socket element parallel to the winding axis. The support is movable in a vertical plane parallel to and perpendicular to its longitudinal axis. A thread suction device and a thread cutter are fixedly connected to this support. In contrast, the thread catcher performs a relative movement with respect to the support or the socket member. In a preferred embodiment, a pivot system is provided for this purpose, which pivot system is pivoted on a support or a socket element. It is advantageous in this embodiment that the thread catcher simultaneously serves as a thread attachment device. For this purpose, two thread catchers are provided in pairs, one above the other. Each thread catcher consists of a horizontal catch tongue oblique to the vertical thread running plane, each catch tongue having a thread trap at an acute angle to its vertical fixing plane. It has been installed. Such thread traps are known per se and are also referred to as, for example, dew traps. The thread trap allows the thread to enter, but prevents the thread from leaving the thread channel again by suitable means, for example by a protrusion projecting into the thread channel. When the thread catcher advances to the outer position, the thread that has been pushed into the traversal movement triangle of one thread by the thread catcher enters into the associated thread trap pair. The trajectory of movement of the thread catcher as well as the thread trap is such that the thread running vertically between the pair of thread traps is located directly in front of the suction nozzle in the inner position of the thread catcher and is fixed to a support or socket member. It is specified that it should go inside the vessel. The thread is now cut by actuation of the thread cutter and is thereby also drawn into the suction nozzle. The running thread is thus only located in the upper thread trap. In order to load the yarn into the empty tube, the support or socket member is moved vertically downwards and then a C yarn loading movement is carried out by pivoting the yarn catcher outwards. In this case, the running thread comes into contact with the hollow tube to which the thread catcher and the thread suction device are associated, and is thereby tensioned between the hollow tube, the thread catcher and the suction nozzle.

An advantage of the present invention is that the suction capacity can be increased due to the arrangement of the thread suction device on the machine frame, so that thread waste can be removed reliably and in the required amount.

The winding device has a complete device for manipulating the thread during bobbin changes. With this device, the timing of replacing the hobbin can be changed at any time. This also makes it possible to operate the winding device at any time, ie to take out a full bobbin and insert an empty tube.

Furthermore, such a winding device is equipped with a bobbin take-out wheel and (
or) It also becomes possible to operate by means of an empty tube carrier.

The bobbin take-off wheel in particular has a receiving mandrel which is aligned in line with the winding shaft and onto which the full hobbin located on the winding shaft is pushed. The bobbin pick-up car is then used to transport the bobbin to a hobbin creel or other pick-up station. The empty tube carrier has an empty tube magazine and a device for taking out the empty tubes and empty tubes from the empty tube magazine and inserting them into the winding shaft to be operated again at ℃. European Patent No. 26471 discloses that a thread handling wheel and a bobbin take-off wheel, which serve at the same time as an empty tube conveyor, run independently of each other along the machine front of a number of winding stations, An N-bin changer is disclosed which is of the type operatively connected to the N-bin exchanger. In short, Yorotsu ξ Patent No. 26471
In contrast to the hobbin changing device known on the basis of the patent specification, in the present invention the thread handling during bobbin changing is carried out by a stationary device assigned to each winding device, whereas in the present invention two independent The operating car, which can be used to take out the bobbin
An operating wheel having a bottle conveying function and an operating wheel having an empty tube conveying and empty tube delivery function can run in front of the machine of the winding device independently of each other, and the winding device and the thread operating device of each winding device It is operationally connected to the thread catching, uncutting, thread suction, stopping the winding shaft, transferring and unloading the full bobbin to the bobbin take-out car, transporting the empty tube and handing it over to the winding shaft, and restarting the winding shaft. In addition, the threading of the empty tube takes place automatically in successive working steps.

In addition to the above-mentioned winding device in a spinning machine for producing chemical fiber yarn, in which the orientation of the filament yarn is produced by drawing out the yarn coming from the spinning nozzle at a high speed using a winding shaft, the spinning machine is particularly suitable for flat yarns. It is also used to produce technical systems, in which the freshly spun filament yarn is drafted by a drawing godet roller device below the spinning tube and then subjected to this type of spinning-drawing→ A particular problem that arises when operating a take-up machine is that the yarn exiting the spinneret is wound around a drawing godet roller before being attached to the take-up device, which draws the thread below the spinneret. It is arranged between the heating device and a fixed yarn path provided at the apex of the traversal movement triangle of the winding device.

When changing the bobbin, the thread is suctioned below the fixed thread guide by the thread operating device mentioned at the beginning, and after preparing an empty tube, it is loaded onto the winding device again, so that the thread is transferred to the multiple godet roller mechanisms. It is not necessary to wind the thread every time the thread is replaced. However, this winding operation is necessary when the spinning nozzle starts spinning, that is, every time the spinning nozzle is cleaned, and every time the drawing Godet roller removes the yarn stuck due to drawing breaks, and when restarting the spinning. Must be done regularly +1 No.

For this reason, it would be highly desirable to also automate the thread winding of the godet opening 2 mechanism and to provide a corresponding thread handling device. This thread handling device can be integrated into the machine for each spinning station, or it can be operatively on standby for a group of spinning stations and can be called up from the individual spinning stations as required.

According to the invention, the yarn handling device for winding the yarn around the smoke-stretching godet roller device of the spinning machine consists of a carriage on which a yarn suction device is mounted, in which case the carriage connects the spinning tube and the fixed yarn path. The rollers are movable in a plurality of planes perpendicular to the axes of the rollers. The movement of the carriage and of the thread suction device begins in each case in the rearmost vertical plane when viewed from the free end side of the godet roller, and in the area of each godet roller mechanism it circulates around the godet roller mechanism several times, and for each circulation The motion trajectory is transferred from the rear vertical plane to the immediate forward vertical plane. In this way, in front of the drawing godet roller mechanism, a yarn suction device capable of three-dimensional movement linearly or spirally is used to suck the yarn below the spinning tube, and the yarn is drawn in by circulating through each godet roller mechanism. It is wound several times around the godet roller mechanism.

For this purpose, it is possible to carry out a continuous linear movement which is repeated in parallel planes with a slight axial offset towards the free end of the godet roller, or alternatively the arm can be fitted with a Cardan joint. It is also possible to make the thread suction device perform a circular movement around the godet roller mechanism by mounting the thread, and the circular movement is repeated in successive axially offset planes in order to avoid overlapping of the thread. be done.

A thread handling device for winding the thread around the godet roller mechanism is suspended, for example, on a ceiling structure above the winding machine, and is movable in a plane perpendicular to the winding axis of the winding machine. Alternatively, the thread handling device may be arranged on a carriage together with a carriage, the carriage being arranged on the floor at one point in the longitudinal direction of the machine.
can travel from one winder to another;
and includes a support and guide V device for the carriage. Carriage movement is programmable and the microprocessor acts on a plurality of drive motors for the carriage.

In consideration of the automated operation of the thread setting device for winding the thread around the godet roller or attaching the thread to the empty tube, the movement of the carriage and associated thread suction device is controlled by the guide tube connected to the spinning tube. The carriage starts at a thread catching position located just before the opening of the thread catching position, and the carriage is returned to this thread catching position again after the thread setting operation is completed. In such a working mode, the yarn is wound around a drawing godet roller and then delivered to a suction nozzle of a yarn setting device of a winding device and then cut, or alternatively, the yarn is wound on a drawing Godet roller and then delivered to a suction nozzle of a yarn setting device of a winding device and then cut, or alternatively, The motion of the device is programmed to sequentially perform all thread manipulation steps in a logical sequence up to thread loading on the empty tube.

<Example> Next, embodiments of the present invention will be explained in detail with reference to the drawings.

1 to 8, a winding shaft 2 is rotatably and immovably supported on the pedestal 1. The winding shaft is suitable for mounting one or more empty tubes 3. The clamping device has a device.On each empty tube, a ξ cage 19 is formed from the threads 10 coming successively.The frame 1 has a linear guide mechanism 12, which The carriage 4 is movable vertically along the carriage 4. The movement of the carriage is assisted by supplying pressurized air to a cylinder 13 having a double-acting piston 14.

Inside the carriage 4 there is particularly a traverse device 6 and a drive roll 5.
is supported. Due to the movement of the carriage, the drive roll 5 and the trassing device 6 can be displaced upward as the package 190 rolls thicken. Traverse device 6
In this embodiment, the reversing threaded roll 7 of the driven 7 type is used.
and a guide grooved roll 9 which is disposed after the reversing threaded roll when viewed in the yarn running direction and partially winds the yarn before reaching the ξ cage 19, and the reversing threaded roll 7 drives the truss thread guide P8 in translation. A yarn preparation device 15, which will be described later, is also supported on the carriage 4.

Furthermore, the reciprocating table 4 has a rotating shaft 16 of rotation 5-17.
is supported. In short, the pivot shaft 16 moves together with the carriage 4. The swivel ζ-17 is movable parallel to itself, that is to say axially parallel to the winding shaft 2. Drives for the traversing device 6, drive rolls 5 and thread preparation device 15 as well as pivoting leno 5-17
The drives for the swivel drive and the axial drive are not shown. The swivel 5-17 is hollow and connectable to a suction pipe. The suction pipe leads to a lint tank (not shown) as described below. A tubular transverse arm 3'9 with a suction nozzle 18 is connected to the free end of the pivot ζ-17. The transverse arm 39 extends parallel to the winding shaft 2, and has a nozzle ξ formed on the winding shaft.
It has the same number of suction nozzles as the number of tubes.

As shown in FIGS. 6 and 7, since a plurality of empty tubes are fitted closely together on the winding shaft 2, a plurality of traverse devices and other related devices can be connected to each other. Must be placed coaxially.

In FIG. 1, the pivot lever 17 is shown in its inactive position. The pivoting lever 17 assumes this inactive position during the formation of the knots, ie during operation of the winding device.

When the package 17 reaches a desired thickness, that is, an allowable diameter, a bobbin replacement operation is started. For this purpose, swivel lever 1
7 is such that, as can be seen from FIGS. 2 and 6, the capture position 1 of the suction nozzle 18 is located immediately in front of the traverse motion triangle (indicated by a broken line in FIG. 6) and in the side edge area. Forced to turn. The suction nozzle 18 is
A suitable thread catching mechanism is provided to capture the traversing thread in the traverse-ζ-movement triangle and guide it in front of the suction nozzle. Furthermore, the suction nozzle 18 has a thread cutting mechanism, such as a thread cutter, which cuts the thread caught in front of the suction nozzle between the suction nozzle and the .xi. hook 219. After cutting, the thread is sucked in by the suction nozzle 18.

Then, as shown in FIG. 3, the forward hand is moved upward by the pressure applied to the cylinder 13, so that the frictional contact between the drive roll 5 and the knot 19 is eliminated. At this position it is possible to replace the full tube with an empty tube 3. For this exchange, the full pipe ξ cage 19 is pulled out from the winding shaft 2,
Another empty tube 3 is fitted onto the winding shaft 2.

The outbound hand is then lowered again as shown in FIG. As a result, the winding shaft 2 is rotated again by the drive roll 5 together with the empty tube 3 attached thereto.

Now, since the turning ζ-17 is turned in the direction of the arrow 20 and at the same time is shifted axially in the direction of the arrow 2'l (Fig. 6), the suction nozzle 18 is at the position ■ (Fig. 6).
and along with the turning movement in the direction of the arrow 22 (FIG. 6), the yarn catching groove 23 (FIG. 8) of the yarn preparation device 15
Insert the thread inside. During the next course of the swivel movement, the swivel ray 5
-17 is again given an axial movement component, so that the pivoting lever 17 occupies the pivoting position shown in FIG. 5, and the suction nozzle 18 occupies the position 2 shown in FIG. In this way, turn 5-17 with arrow 24 (Fig. 6)
Given an axial movement in the direction , the suction nozzle 18 reaches the position shown in FIG. During this movement, the thread slips into the thread capture notch 25 provided in each empty tube 3. The thread catching notch is a narrow annular slit into which the thread is tightened and cut. This tightening action and cutting action are such that the direction of movement 27 of the thread is the direction of movement 26 of the empty tube 3.
(Fig. 5). Immediately after the thread is cut off, the pivot ζ-17 is immediately returned to its inactive position as shown in FIG. Otherwise, the roll will become thick ξ
This is because the cage blocks the movement path of the swing lever.

At the same time, the yarn preparation device 15 is also activated.

Moreover, since the plate 29 is configured to enter into the plane of the drag/ζ-stroke triangle at the advanced position, when the plate 29 returns, the yarn moves through the trano-ζ-stroke at a speed defined by the return speed of the plate. sliding along the scraping edge 30 and the braking edge 28 toward the midpoint of the
A preparatory winding 31 is then formed on the empty tube, which preparatory yarn winding is located outside the range of the traversing stroke, that is to say outside the ξ thread to be formed on the empty tube.

The structure and suction nozzle 1 of the embodiment shown in FIG.
8 is essentially equivalent to the embodiment described with reference to FIGS. 1 to 8. In this embodiment, each suction nozzle is part of a telescopic tube, which is mounted on a cradle below the winding device. As a result, the suction nozzle has an additional degree of freedom and can therefore be guided in a radial movement relative to the pivot axis 32 of the telescope tube 33, in addition to a pivoting and axial movement. However, in other respects the movement course corresponds to the positions I, n, m, IV (FIGS. 6 and 7). The only difference is that the inactive position can also be selected to be tangential to the bottom plate of the pedestal 1, which is obtained by the additional degree of freedom of movement of the suction nozzle 18. Each telescope tube 33 is located on a common center tube 41 and is pivotable by a common pivot axis 32 .

In the embodiment shown in FIGS. 10 and 11, the pivot shaft 16, which forms the pivot point of the suction nozzle 18, is fixedly mounted on the pedestal 1.

An advantage obtained by mounting the pivot shaft 16 in a fixed position is that the weight of the carriage is not increased by the thread catching mechanism, the thread cutting mechanism, the suction device, the thread mounting device, etc. The movement course in the turning direction and the axial direction is the first
This is the same as in the embodiments shown in FIGS. 9 to 9.

Another important difference (although this can also be realized if the pivot axis is provided on the carriage 4) is that the yarn catching mechanism, the suction device and the yarn loading device are also suitable for starting spinning at the same time. It is that you are.

In this case, "first spinning" means the operational stage at which spinning or spinning begins. Details of the automated starting operation are disclosed in DE 24 38 364. In this known technique, bobbin exchange is automated by using a winding device with two winding shafts, but
In the embodiment shown in FIGS. 10 and 11, both the starting spinning and bobbin exchange are automated by the same device.

For the first spinning, the embodiments shown in FIGS. 10 and 11 have the following equipment.

A guide tube 36 guided in an arc shape is connected to the yarn protection tube 35 through which the yarn 1o or single fibers arrive from the spinning nozzle. The guide tube has a slit 37 on the side closer to the center of curvature. The guide tube 36 terminates in an opening 38. The suction nozzle 18 is located in front of the opening 38 in the starting position and is movable so as to substantially close the opening. By means of the air flow guided through the spinning tube 35 (and assisted by the suction flow of the suction nozzle 18), the yarn is blown through the guide tube 36 and is captured by the suction nozzle 18. In this case, the thread is subjected to a tensile force, so that it advances through the slit 37. By pivoting the pivot lever 17, the thread 10 is drawn into the apex thread path 11 of the traversing triangle.

The pivoting lever 17 simultaneously carries out an axial movement during the course of the pivoting movement, so that it passes through the position (2). At the same time, winding of the full tube cage is stopped and replaced with an empty tube. The suction nozzle is then moved to position (Fig. 11). The thread is thereby inserted into the thread preparation device as described above. By axially shifting the suction nozzle to position (3), the thread enters the thread catcher notch 25 of the empty tube 3, whereby the thread is entrained by the empty tube and is severed between the empty tube and the suction nozzle. In this way, the yarn first forms a bead P-shaped body and, after actuation of the yarn preparation device 15, forms a yarn preparatory winding 31, which, when caught by the traversing device 6, is wound onto the empty tube and the ξ thread cage. Form. The thread handling during the next bobbin change takes place in the same way as in the previous example, but in this case in particular the catching position I is located in the plane of the traverse movement triangle.

12 to 14 show a suction nozzle as well as a yarn catching mechanism and a yarn cutting mechanism attached to the suction nozzle.

A plurality of suction nozzles 18 are arranged in a tubular transverse arm 39 which is open at one end 40 . The number of suction nozzles is equal to the number of ξ cages to be formed on one winding shaft. The suction nozzle 18 is not perpendicular to the axis of the transverse arm 39, but is advantageously slightly oblique, so that the thread drawn into the suction nozzle is guided into the transverse arm 39. A positive-pressure air conduit 42 is fixed to the transverse arm 39. From this positive-pressure air conduit 42, via a hose fitting 52, an annular passage 43 forming a component of the suction nozzle 18 is connected. Pressurized air is supplied. The positive pressure air flow entering the suction nozzle 18 generates a suction flow of the suction nozzle that sucks in the yarn.

In FIG. 13, the traverse movement stroke is shown in broken lines, and one end position of the traversing thread guide 8 is shown in solid lines, and the other end position is shown in broken lines. The traverse/ζ-thread guide 8 moves the thread in the vertical plane between the apex thread path 11 and the path of movement of the traverse thread guide 1″8.
It is caused to reciprocate within a so-called traverse motion triangle. To interrupt this movement, the suction nozzle 18
The catching tip 45 of the thread catching mechanism 44 is brought close to the traversing triangle so as to penetrate into the plane of the traversing triangle. As long as the thread is located to the left of the catching tip 45 as seen in FIG. 13 when the catching tip 45 enters the traversing movement triangle, the thread slides up along the sliding edge 49 inclined towards the traversing movement triangle; The thread is then held in the recess 46 of the traversing thread guide 8. 13th
When the traversing thread guide δ returns from the solid line end position shown on the right in the figure, the thread slides down along the catch edge 48 beveled in the same direction into the thread cutting mechanism and in front of the suction nozzle 18. .

In the embodiment shown in FIGS. 12-14, the thread cutting mechanism is a component of the thread catching mechanism. The thread catching and cutting mechanism consists of one thin metal plate, which is attached to the suction nozzle 1.
It is fixed to the bottom of 8. Since this thin metal plate has a surface portion 47 that is oblique to the thread running direction, this surface portion and the orifice surface of the suction nozzle 18 form an acute angle, and the thread enters into this acute angle range. . This surface part 4
7 is cut with a cutting notch 51 which is wide in the upper region but tapers in the thread running direction and has a knife-like sharp edge. The catching edge 48 of the catching tip 45 reaches this cutting notch 51 . Now, when the thread traveling in the direction of arrow 27 enters this notch 51, the thread is grasped at the tip of the cutting notch and is cut by the tensile force applied to the thread from the screwdriver. The suction nozzle can then suck in the yarn end located above the cutting notch, which suction
1 is open in the direction opposite to the thread path movement direction 27 and therefore does not exert a holding force on the thread. The thread is thus sucked out by the suction nozzle 18. The suction nozzle 18 has a small running groove 50 that guides the yarn.
is formed. Behind the annular groove 43 the thread reaches a positive air flow. In the tubular transverse arm 39 the positive pressure air flow merges with the air flow drawn in through the open end 40 .

FIG. 15 shows a configuration of a unit comprising a center pipe 41, a rotating renocouple 17, and a horizontal arm 39 on which a plurality of suction nozzles 18 are installed. Center pipe 41
is attached to the frame 1 (FIGS. 10 and 11) or to the outgoing compound (FIGS. 1 to 5), and is pivotable about a pivot shaft 16 and shifted in the axial direction at the pivot shaft 16. Possibly supported. A step feed motor 62, a gear 53, and a gear 54 are used for the swing drive, and the gear 54
remains engaged with the gear 53 even when the center tube 41 is shifted in the axial direction.

The axial shift is produced by a guide grooved drum 55 mounted on the center tube, the guide groove 56 of which engages with a stationary pin 57. Note that the shape of the illustrated guide groove 56 is arbitrarily selected for drafting reasons, and
It should be noted here that the pivoting movement and the axial shifting movement of 8 do not exactly correspond to the previously described movement course.

The pivotable and axially shiftable part is the coupler 58.

It is open to In the illustrated example, the coupler 58 consists of only two tube sections, which fit coaxially and airtight into each other, one tube section being fixedly connected to the hose 59. while the other tube piece is in the center tube position.
It is connected to a rotor and is pivotable and axially shiftable.

FIGS. 16a and 16b show an outlet of the spinning tube 35 or a guide tube 36 connected to the spinning tube and having a slit.
In order to supply the yarn 10, that is, the filament yarn received at the outlet of the drawing cordet roller device 71, the movement sequence that must be sequentially performed by the carriage of the yarn feeding device and the yarn suction device provided on the carriage is explained. The water is famous for its front and side views. The stretching godet roller device 71 includes a plurality of godet roller mechanisms 72, 72', 72J/, 72/
/7, and is arranged between the spinning tube 35 and the vertex thread path 11 associated with the winding shaft 2 shown in FIG. 1 or FIG.

As soon as the filament yarn is sucked by the yarn suction device 70 in the capture position (starting position of the carriage of the yarn feeding device), the yarn guide P is actuated and the yarn is separated from the solenoid ξ ration roller 73 . The yarn guide is attached to the back wall of the machine and can enter and exit parallel to the winding shaft 2.

In order to feed and wind the yarn 10 onto the first godet roller mechanism 72, the feeding roller 7 and the associated running roller 75 move in the rearmost vertical plane in the direction of the movement arrows 76° 76', 76", 76/// by a total of 360 degrees by the carriage and its thread suction device 70. Although the circulation movement of the carriage is a linear movement, the godet roller mechanism 72 The thread 10 is wound once.The carriage is then shifted a short axial distance in the direction of arrow 77 into a parallel vertical plane in front of said rearmost vertical plane.

Following this, the godet roller mechanism 72 is wound with the line for the second time. This motion cycle is repeated a number of times until the godet roller mechanism has been wound a sufficient number of times and is capable of absorbing the required holding and stretching forces without slippage. The carriage then travels in the direction of the yarn tangentially exiting the supply godet roller 74 towards a processing chamber 78, e.g. Wrap l○ around it. Of course, the cover of the processing chamber 78 is opened by an operating device (not shown) before the carriage moves. The movement cycles required in this case are marked by arrows 81.81', 81", 81" and are repeated several times, with an axial shift movement in the direction of arrow 82 at the end of each movement cycle. This is done to avoid overlapping the yarn. Processing room 7 after thread winding
8 is closed again by the operating device. In this way, the carriage moves to the godet roller mechanism 72 which continues in the thread running direction.
It may be several times in the direction of the arrow around “+72”, but each time it is 3
Since the thread is controlled to circulate by 600 threads, a plurality of threads are spirally wound around the godet roller mechanism.

Yarn separation during processing and winding of the multi-yarn is achieved by rotating the shaft at the end of each movement cycle so that the yarn windings in each godet roller mechanism have a pitch greater than the thread spacing of the sli-like spread yarn. This is done by shifting in the direction.

After winding the yarn around all the godet roller mechanisms of the drawing godet roller device 71, the yarn is wound onto a winding spatula F'' (not shown) having a bobbin turret, such as the one disclosed in German Patent No. 2461223, for example. Alternatively, the yarn is transferred to the suction nozzle 18 of the yarn feeding device.After the yarn transfer, the yarn 10 is cut by the yarn cutter 83 and the carriage is returned to its starting position at the end of the spinning tube 35 or guide tube 36. At the same time, the supply of pressure to the yarn suction device 70 by the positive pressure air supply section 84 is stopped.

The yarn 10 supplied to the drawing godet roller device 71 is
After transfer to the yarn feeding device for the winding spatula P shown in FIGS. 1 to 14, the yarn 10 is transferred to a typhoid nozzle for additional working steps, e.g. It is possible to carry out the steps of inserting the thread 10 into a stationary apex thread path belonging to each traverse-ζ-motion triangle, and into a thread tension measuring device and a thread breakage monitor. .

In FIG. 17a, the drawing godet roller device 71 is again shown in a side view. As can be seen from the drawing, the thread 10 is wound several times around individual godet roller mechanisms arranged axially, then fed onto a winding shaft and wound onto two parallel empty tubes 3. Thread suction device 70
17b, the carriage has a substantially closed track along a guide rail 85 parallel to the front of the machine (perpendicular to the plane of the drawing). It moves back and forth in a curved manner. After completing the movement cycle of FIG. 1 in godet roller mechanism 72, the carriage is shifted in the direction of arrow 77 into the next vertical plane closer to the free end of the godet roller. The axial feeding of the godet rollers can be carried out continuously or intermittently until the yarn is wound around each godet roller mechanism 72 to 72'' a sufficient number of times. Next, the carriage is next (r)-? It is then shifted towards the chit roller mechanism 72', in which case the carriage advantageously remains in the vertical plane in which the already wound thread 10 runs out of the godet roller mechanism 72.

The winding of the subsequent godet roller mechanism in the thread running direction takes place in the same manner as described above.

In particular, the thread suction device 70, which is fixedly connected to the carriage, can be moved vertically in approximately the same way as the trolley of the winding mechanism and is mounted on a guide rail 85 arranged parallel to the longitudinal front side of the winding machine. It can be translated in parallel along the desired course of movement. The thread suction device 70 can also be moved on a carriage axially parallel to the godet rollers, in which case each movement of the carriage, indicated by arrows 86, 87, 88, is carried out in steps controlled by, for example, a microprocessor. Guaranteed by feed motor.

FIG. 18 shows a different embodiment of the thread changing device of the winding device. The thread changing device is movably mounted on the machine frame 1, and particularly preferably on the side of the carriage 4 of the winding device facing the thread 10 and the traversing device 6.

The connections for the pressure medium have been omitted for clarity. A socket member 93 is fixedly coupled to the carriage 91 and extends substantially horizontally on either side of the vertical pillar 93 and has a sliding piece 94 within the socket member.
can be reciprocated by control. In order to drive the sliding piece 94 in one direction or the other direction, a double-acting piston-cylinder unit 95, a sergi motor, etc. are used, and the piston-cylinder unit 95 is fixedly connected to the socket member 93, Moreover, the piston rod 96 is engaged with a pin 97 of the sliding piece 94.

A first rotating shaft ζ-98° 1 is rotatably supported at one end of the sliding piece 97, and is coupled to the shaft of a drive motor 99 in a relatively non-rotatable manner. Second turning lane! -9a,
2 is rotatably supported at the other end of the sliding piece 94, and is interlocked when the drive motor 4-99 is operated. This is because a chevron rail 101 is attached to a suitable rotating bin 100 provided at the end of the swing 6-9 a, 1.98. The thread catcher 102 has at least two thread catchers 102 arranged at a distance. The chevron rail 101 has packages 19 to be formed in parallel on the associated winding shaft 2 (not shown in FIG. 18).
The same number of thread catchers l○2 are arranged in parallel.

The chevron rails 101 are arranged in the range of the yarn catchers 102 located above and below, respectively.
A cut-through portion 104 is provided in front of the thread 8 to allow the thread 10 to be guided.

The box of the thread suction unit 103 is the carriage 9
1 is connected by a flexible hose 105 to a negative pressure source (not shown), in order to compensate for the length of the thread 10 during vertical movement, so that the suctioned thread 10 is transferred to the collecting gauge 60''. transported to.

A thread cutter 106 is fixed to the box of the thread suction unit 103 below the suction nozzle 18. The yarn cutter is configured so that the yarn 10 captured by the yarn catcher 102 is absorbed by the yarn suction σ1.
It is activated when it is guided in front of the section 103 and captured by the suction nozzle 18.

Therefore, the thread changing device shown in FIG. 16 can be moved up and down vertically in the direction of the double arrow 109 by means of a piston-cylinder unit 92, and in addition, by means of a piston-cylinder unit 95, the moving piston rod 96 can be moved up and down. A linear translational movement in the direction of the double arrow 110 can be effected through the double arrow 110. This translational movement is superimposed with the turning movement of the chevron 2-rule 101 by activating the drive motor 99 to turn the turning ζ-98°1 and 98.2 in the direction of the double arrow 111. Is possible. Based on the superposition of the rotational movement by the drive motor 99 and the reciprocating translational movement by the piston-cylinder unit 95, the stroke and rotation of the piston-cylinder unit 95 are controlled.

Almost every point in the horizontal plane of is controlled.

Next, the working mode of the thread changing device will be explained with reference to FIGS. 19a and 19b. In FIGS. 191L and 19b, the winding device is shown in a front view, and the thread changing device is shown in a side view, and the symmetrical symbols of the members are indicated by the same symbols as in FIG. 18.

In order to change the bobbin, the carriage 91 of the thread changing device is moved to an upper position in order not to interfere with the winding thick blade, ξ sok, and jig 19, and the outbound hand that has been retracted above the winding device. is in a state of Due to the operation of the drive motor 99 for turning, the yarn catcher l○2 advances in its horizontal plane and enters into the yarn running plane between the fixed apex yarn path 11 of the traverse movement triangle and the traverse yarn guide 8. leading to.

As a result, the yarn 10 is released from the truss/S-thread guide 8 and the guide grooved roll 9, and the yarn 10 is released from the winding shaft 2 on which the yarn trump 108 of the yarn catcher 102 is located.
A draw thread winding is wound onto each nozzle ξ cage 19 in the vertical plane. At this point, the winding shaft 2 is already braked. However, before the thread 10 relaxes and hangs down, the thread cutter 106 is actuated, and the fed thread lO is caught and sucked by the suction nozzle 18 of the thread suction section 103.

After braking the winding shaft 2 and replacing the nozzle cage 19 with an empty tube 3, the carriage 4 is moved to a winding system with a guide grooved roll 9 or (as shown in FIG. 1, an additional drive roll 5). In the case of the device) the drive roll 5 is lowered until it drives the empty tube 3 and accelerates it to full circumferential speed. Now, as shown in FIG.

(For example, USSR Pat. No. 2,547,401 or U.S. Pat. No. 41
46,186), the yarn is in this case
The stationary apex of the traverse motion triangle is prevented from entering into the traversing plane between the thread path and the traversing thread guide 8.

The piston-cylinder unit 95 is now pressurized, so that the thread catcher l○2 is moved axially parallel to the winding shaft 2 and the thread 10 is moved into the conventional thread catcher, in this case towards the suction nozzle 18. The cutting of the running yarn 10, the formation of a yarn preparatory winding in each empty tube by the operation of the yarn preparatory winding forming device 14, and the automatic capture of the yarn 10 by the traverse yarn guide 8 are performed in sequence. be exposed. After the initial thread winding is performed, the drive motor 92 and the piston-cylinder unit 92 are operated, and the thread changing device is moved to the chevron knoll 101.
