description

The present invention relates to a method and a device for removing defective winding material.

The method according to the invention and the device according to the invention are particularly suitable for the production of — error-free — bundles from elongated winding material, such as from cables, metallic wire, in particular wire made of copper, steel, etc., insulated metallic wire, strands, in particular copper, insulated strands, Glass fiber, d. H. essentially all types of strand-like material, the nature of which allows winding.

Such a strand-like, rollable Good place for example in automotive engineering ^"or mass-, for example, in the wire harness manufacturing, generally in electrical wiring or electrical appliances use.

A method and a device for producing containers, in this case a ring winding system for producing cable rings, wire rings and the like, are known from DE 196 14 585 Al.

From DE 196 14 585 Al it is known that the ring winding system, a vertical double winder, works with two winding cassettes that can be alternately wound. For this purpose, this double winder has two winding stations, which are arranged offset by 180 ° on a pivotable support plate. These swiveling and thus non-stationary winding stations each have a winding cassette that can be rotated by a drive motor. The cable rings are alternately wound in the winding stations by winding a cable K onto the rotating winding cassettes to produce the cable rings. After the winding process, the cable ring is separated from the respective winding cassette.

A swiveling device swivels the support plate or the winding stations and thus the winding cassettes by 180 ° from the respective position to the next position, with the winding cassette currently located there being wound only in a spatially fixed position (winding position).

A sensor device detects the degree of filling of the winding cassette currently in the winding position and interacts with a control device in such a way that a pivoting movement of this pivoting device - and thus the winding station from this winding position - is effected as soon as this winding cassette has reached a predetermined filling degree.

Furthermore, as described in DE 196 14 585 A1, a cable laying device is provided which effects a separation of the cable K and the laying of the cable K on this winding cassette.

As DE 196 14 585 A1 further describes, a stationary laying device feeds the cable K to the winding cassette provided for winding and in the winding position in accordance with a predetermined laying characteristic. For this purpose, the stationary laying device has an inlet and a laying roller, which can be moved vertically in order to feed the cable K in accordance with the intended laying characteristic.

Further methods and further devices for producing packages with coils oriented horizontally during winding are also known from the prior art.

Containers produced with such systems, as described, are often - and increasingly - in highly complex systems with high requirements for safety and functionality or with low requirements

Failure probabilities used. As a result, customers also require such containers that they are error-free (O-error strategy).

Previously known devices and methods for producing defect-free packages in such winding machines as described provide that the winding material to be wound, as a rule during winding, is monitored for defects in the winding material.

Corresponding measuring and monitoring systems are known, for example a so-called "market tester", for example available from Beta Lasermike (available on March 9, 2005 at: http: // www.betalasermike.com/Languages/German/GermanLiterature / SparkTesterGerman.pdf), which checks the condition of the material to be wound on the basis of an dielectric strength, and also optical, measuring and monitoring systems, which monitor or detect knot formation in the material to be wound.

If - during the winding of a winding spool - an error in the material to be wound is detected, the winding of this spool is interrupted, the unwinded spool is removed from the winding device and the - until it is broken off - the partially wound package is removed. The disadvantage of this is that a lot of waste, which is also unnecessary, is generated here, which largely includes faultless winding material, which leads to high costs here.

Alternatively, certain devices also provide that - if a fault is detected - the spool currently in the winding is finished, this or the bundle is then manually rewound or rewound, the defective winding material being manually cut out of the bundle and excreted.

However, this procedure is due to the necessary after-treatment, i.e. because of the rewinding of the coil, complex, time-consuming and consequently cost-intensive.

Furthermore, winding coils, for example NPS coils, with different coil sizes, in particular different coil heights, and / or with different flange diameters are known.

Rail systems for realizing linear and curved movements, for example a ring and rail system from Zimm Maschinenelemente GmbH & Co., are also known.

Slip ring systems and rotary unions are also known.

The present invention is based on the object of providing a method and a device for separating defective winding material, by means of which faultless containers can be produced more easily and more cost-effectively than is known from the prior art.

This object is achieved by a method and a device for separating defective winding material with the features according to the respective independent patent claim. Advantageous embodiments and developments are the subject of the dependent claims. The subjects of the subclaims relate both to the method according to the invention and the device according to the invention for separating out defective winding material.

In the following, defective winding material is generally understood to mean part of a winding material, for example an area in a cable, where the state of the winding material deviates from a desired state of the winding material.

In particular, defects in the material to be wound are damage to the material to be wound, in particular damage to insulation of the material to be wound, such as inclusions of dirt, (extruder) residues, particles, etc. in the winding material insulation or open positions in the winding material insulation, or diameter deviations from the nominal diameter in the winding material or also knots formed in the winding material.

The device according to the invention for separating defective winding material has a, in particular disc-shaped, winding body, which can be wound with winding material, in particular defective winding material.

It can particularly preferably be provided that the, in particular disk-shaped, winding body, also referred to below as “scrap disk”, has a conical or a cylindrical shape with a conical extension.

It can also be provided that the scrap disc is made of steel, aluminum or plastic.

It can also be provided that the scrap disc has a divisible (winding) core or - corresponding - means by which the diameter of the scrap disc or the disc diameter can be adjusted, varied or changed. Further, positioning means are provided according to the invention with which the particular ^■ disc-shaped winding body of a positionable with winding material to be wound reel spool with respect to.

In particular, a positioning is provided here in which the winding body is arranged and / or movable in the longitudinal direction of the winding spool or coaxially to the winding spool. In this case, it can also be particularly preferably provided that the winding body is in direct or indirect contact with the winding spool at least temporarily, for example during the winding of the winding spool.

The positioning means can be arranged directly on the winding body or on the scrap disk or can be integrated into the latter.

These can be, for example, coupling means and / or engagement means for a, in particular detachable and / or non-positive and / or positive, coupling of the winding body to the winding spool, in particular to a flange of the winding spool, and / or also for a coupling of the winding body to a spool receiving device , such as centering and / or (driver) pins.

Furthermore, these positioning means can also be means by which the winding body can be actively positioned, such as adjustment means by which the spatial position and / or orientation of the winding body can be adjusted, for example height adjustment by means of a linearly movable (support) arm.

In this case, it can be particularly preferably provided to integrate the winding body into a coil take-up device, so that the winding body is also positioned by adjusting the coil take-up device - when taking it up and releasing it from a winding spool. It can particularly preferably be provided that the change in the diameter of the scrap disk depends on the positioning of the scrap disk. For example, the scrap disc can be designed in such a way that its disc diameter can be reduced if the scrap disc - in particular temporarily, ie coupled to the winding coil during winding of the winding coil - is separated from the winding coil.

Furthermore, winding material guiding means are provided according to the invention, with which the winding material, in particular the defective winding material and / or in particular temporarily during winding of the winding spool, can be moved from a winding region of the winding spool into a winding region of the, in particular disc-shaped, winding body.

The winding material guiding means are particularly preferably designed as a roller system with a plurality of, in particular cylindrical, rollers or roller bodies arranged radially offset around the winding body, for example two rollers arranged offset from one another by 180 °.

Furthermore, it can be provided that the rollers are arranged on the circumference of a rotating ring which is arranged coaxially to the winding body, in particular can be driven by means of a drive motor, and can be rotated with respect to the winding bobbin.

It can also be provided that the rollers are adjustable in height. This height adjustment can be effected by means of a cam disc or pneumatics.

The roller system particularly preferably interacts with a laying device, loops or loops ascending or descending are formed in the winding material when the laying device cooperates in particular with a movement of the laying device along the coil axis and a radial movement of the rollers, which loops or loops in the winding material , Winding goods from the winding spool to the Allow the winding body or to the scrap disc - and back again.

The formation of a winding material loop is particularly suitable for over the winding material. to raise the flange of the winding spool.

Furthermore, it can preferably be provided here that the laying device is set up in such a way that, if a defective winding material is detected, a laying roll of the laying device is moved, in particular temporarily, to a position (scrap position) in which the, in particular faulty, winding material is placed on the Scrap disc is windable.

Furthermore, measuring or monitoring systems for monitoring the winding material and / or for detecting errors in the winding material can be provided, such as a "savings tester".

A function / control unit can also be provided. be, which controls the winding of the winding body or the scrap disc taking into account the winding diameter, flange diameter and / or winding speed of the winding spool and / or the scrap disc diameter.

In the method according to the invention for eliminating defective winding material, a winding material to be wound is monitored for errors, particularly when winding a winding spool. If an error is found in the winding material, the winding material to be wound, in particular the defective winding material and / or in particular temporarily during the winding of the winding spool, is relocated from a winding area of the winding spool, in particular into a winding area of another winding body.

Furthermore, provision can then preferably be made for the winding material to be temporarily moved there, that is to say defective, to the other winding body and wound there the winding of the winding spool is released from the winding body and cut out.

In a particularly preferred further development, the following steps are carried out:

If an error occurs in the winding material during winding of the winding spool, a laying roller of the laying unit is temporarily moved from a first current laying position into a scrap disk position selected for laying the winding material on the winding body or on the scrap disk,

the laying unit temporarily moves the winding material, in particular for a specifiable winding duration and / or winding distance, which can or can be specified depending on a winding speed, onto the scrap disc, at least the defect in the winding material being transferred onto the scrap disc,

- Then the laying unit for further winding of the winding spool, in particular for further winding a predetermined laying characteristic, is again moved into a second current laying position, which depends on the first current laying position.

It is particularly advantageous here that the winding is not broken off or does not have to be broken off.

Further advantageous aspects of the invention are mentioned below.

It also proves to be of particular advantage in the invention that it can be used with any winding device, regardless of its type, i.e. for both vertical and horizontal winders, as well as their direction of rotation can be used independently.

Furthermore, with the invention, the error elimination can already be carried out during the winding, ie with the machine or system running. Thus, by means of the invention, a winding device, in particular a double winder, can be created, which enables completely continuous operation of the system while at the same time ensuring an O-Fahler strategy.

Continuous operation is essentially made possible by the fact that according to the invention - if a defect in the winding material is detected - it is temporarily moved to another winding body while the system is running, after the winding material has been moved back it continues until it is completely wound - or until the next temporary transfer a further detected winding fault - is laid on the winding spool.

Interruptions, runtime stops of the system and reel changes as known from the prior art are not necessary according to the invention.

Complex post-treatments, such as rewinding and cutting out winding material errors in fully wound coils, which are known from the prior art, can also be avoided in this way in the invention.

Precisely because of this, the invention enables a simple, time-efficient and inexpensive O-fault strategy to be implemented in the manufacture of containers.

Furthermore, the invention enables faulty material to be wound or pieces of material to be wound in very short lengths.

Further advantages, features and possible uses of the present invention result from the following description of exemplary embodiments in connection with associated drawings. The electrical cables K described there are made of strands and insulated, such as z. B. for the production of wiring harnesses in the automotive industry or generally for electrical wiring of electrical devices. However, it is pointed out that the term cable K, as used in the description and in the claims, should in no way be understood as a restriction for the winding material to be processed.

The invention is described below on the basis of typical applications, namely the winding of cables K, in this case automotive cables.

The first embodiment of the invention according to FIGS. 1 to 13 is a double winder in a vertical construction, in which two stationary winding stations for winding vertically oriented, first and second bobbins S1 and S2 and one unsteady laying device, which winds the coils S1 and S2 according to a predeterminable winding characteristic and circles around the stationary winding stations when the cable K is moved.

However, the explanation of the invention is in no way to be understood as a restriction of the invention or the applicability of the invention.

The symbolically indicated cable K runs, in the illustration according to FIG. 1 on the left-hand side, coming from an extrusion system into the system and initially runs over a pull-off disk 1a. In order to prevent the cable K from twisting, the cable K is then guided over a lifting roller 1b.

A flat belt 2 is guided around the pull-off disk Ia, by means of which the cable K is braced against the pull-off disk Ia as it passes over it.

The double winder has an automatic shutdown (not shown), i.e. a device for quick stop, which stops the system as quickly as possible in the event of a wire break or a fault during the transfer process.

The bracing of the cable K against the pull-off disk Ia by means of the flat belt 2 prevents the cable K from tearing or jumping off the rollers during a quick stop in the previously running extrusion system. The cable harness remains in the above system, i.e. here in the extrusion line, excited.

This minimizes the set-up time for restarting the system or the double winder. The stopping scrap is deposited in front of the double winder.

Subsequently, ie after passing through the pull-off wheel 1a and the lifting roller 1b, the cable K then runs over a dancer 3 with a first dancer roll 3a and a second dancer roll 3b to the laying device 4.

Instead of individual dancer roles 3a and 3b in dancer 3, role sets 3a ^N and 3b ^v can also be used.

The laying device 4 serves, in addition to the winding of the coils S1 and S2 in accordance with the predeterminable winding characteristic, also for laying or relocating the cable K and for laying the cable K from the full to the empty winding spool.

The distance between the dancer rolls 3a and 3b is z. B. variable via a spring or a pneumatic cylinder, as is known in the prior art, so that inconsistencies in the cable feed are compensated. Furthermore, the dancer 3 serves to regulate the coil speed.

As can be seen in FIG. 2 and in particular in FIGS. 11 and 12 and also in FIGS. 1, 3 and 6, the laying device 4, in short also laying 4, is in this double winder - in particular for the re-routing of the cable K. from the first to the second winding station or from the first spool S1 to the second spool S2 or vice versa - movably arranged or mounted on the housing 45 of the double spool.

For this purpose, a special running track carriage system 40, as is generally known from the prior art, is provided in this case, consisting of running tracks 43 arranged in a closed, circular-like orbit and a running carriage 42 which is guided in the running tracks 43 and is accordingly movable . The laying 4 is mounted on the carriage 42.

As can be seen from FIG. 2 and FIGS. 11 and 12, the running rails 43 form an essentially oval or elliptical path, in the interior of which - approximately at the focal points of the ellipse - the two winding stations are stationary are arranged.

As can be seen in particular in FIGS. 1, 3 and 6, the track-carriage system 40 is fastened to the housing of the double winder above the winding stations.

The drive 41 for the carriage 42, which moves it and thus the laying 4 - depending on the winding direction counterclockwise or clockwise 46 (see FIGS. 11 and 12) - in the running rails 43, is as in FIG can be seen, also mounted on the housing 45, in this case on a frame part, of the double winder.

When the cable K is relocated, the laying 4 thus circles around the winding stations, depending on the winding direction (FIGS. 11 and 12).

As can also be seen from FIGS. 3 and 6, the running rail-carriage system 40 has a rotary lead-through or rotary lead-in 50 that is moved or moved along linearly for the current and sensor supply 53 provided with a cable drag 52 with a hollow shaft 51 for the cable inlet 54 in the center. For this purpose, the double winder is designed to be open at the top in the driving range of the rotary inlet 50.

In order to guide the winding material or the cable K, movable deflection rollers 55 are attached above the running rail / carriage system 40, which adapt to the direction of the cable K or cable harness and thus ensure that the cable K is guided straight and securely from the dancer 3 to the mobile at any time or non-stationary installation 4.

Otherwise, as is also known in the prior art, the laying device 4 has feed rollers 13 and a laying roller 14.

The feed rollers 13 and the laying roller 14 move in the direction of the double arrow 15 up and down, wherein the movement is controlled by a control device (not shown in FIG. 1).

As a result, a predeterminable winding pattern or a predeterminable winding characteristic can be generated on the winding spools S1 and S2. 5b shows two different winding patterns of an NPS coil wound by the double winder according to the embodiment. The winding pattern of the left bobbin corresponds to a normal winding, whereas the winding pattern of the right bobbin has a special conical bevel in an area at the top created by an additional sliding step (with X3 = Xl / 2, with deviations (2 +/- Δx) being adjustable) Has flange.

The movement of the traverse roller is a (in Figure 6 only schematically indicated) motor-driven ^'ball screw 16 causes.

In the exemplary embodiment, as can be seen from FIG. 2, the winding station denoted overall by 100 has two stationary winding stations which are arranged next to one another and can be fitted in parallel with the winding coils S1 and S2, namely a first stationary winding station 101, which in the illustration according to FIG an unwound winding spool S1, and a second stationary winding station 102, which carries a wound winding spool S2 in the illustration according to FIG.

Each winding spool S1, S2, for example NPS coils known in the prior art, of which different designs with different spool heights / sizes, different flange sizes and different winding patterns are shown in FIGS. 5a and b, have an upper flange 25, which is one represents essentially flat circular plate and on which the actual winding core 26 is arranged in one piece.

The winding core 26 can be cylindrical - but can also be conical, as in the exemplary embodiment. At the lower part of the winding core is a second one from the winding core 26 Detachable flange 27 is arranged, which also represents a substantially flat circular plate.

Upper flange 25, winding core 26 and lower flange 27 are rotationally symmetrical to a vertical axis of rotation 20, which is also the axis of rotation of the winding core during the rotational movement or winding movement.

Furthermore, in the double winder 100, the two winding stations are each equipped with a receiving device consisting of an upper part or upper receiving part / device with a quill 24, and a lower part or lower receiving part / device 23 for the bobbin S1 or S2.

The quill 24 of each receiving device is, as can be seen in particular in FIG. 9, adjustable in height in a vertical linear guide 17. By means of a worm gear motor 28 with pinion and toothed rack, the quill 24, as is also illustrated in FIG. 3 with the right quill shown there, can be adjusted in height in the linear guide 17, self-locking when at a standstill, any height - between an upper end position , a coil release position, and a lower end position, a coil receiving position, can be approached.

The linear guides 17 are, as can be clearly seen in FIGS. 3 and 9, attached to a central column 80 which is approximately rectangular in cross section and which is arranged between the winding stations 101, 102.

Each upper receiving part of the double winder according to the embodiment also has a device 30 on its side facing the winding spool for rejecting faulty cable pieces or scrap.

This device 30, which can be seen in FIGS. 1, 3, 8 and 9, in particular in FIGS. 8a and b Functionality is illustrated includes a so-called conical scrap disc 31, for example made of steel, which has a conical extension with a smaller diameter than the scrap disc 31 itself at its lower end. The extension is brought into engagement with the upper flange 25 of a winding bobbin when the upper receiving part is lowered into the coil receiving position.

The scrap disk 31 is further designed such that when the upper receiving part is lifted, its diameter is reduced, for example by 1 mm, or tapered, as a result of which scrap or coiled material wound on the scrap disk 31 is not also lifted, but after the sleeve 24 is separated from the winding spool remains on the upper flange 25 of the winding spool (see FIGS. 1, 3, 5b) and is exchanged with it. After the upper flange has been separated from the winding core, the scrap or the scrap loops can be deposited in the internally hollow conical winding core and / or cut off from the container.

Furthermore, the device 30 has a turntable 32 arranged above the scrap disk 31. On its circumference, two rollers R1 and R2 are arranged opposite each other in a 180 ° offset.

The two rollers R1 and R2 are each supported at their upper end in the rotating ring 32. The distance between the two rollers R1 and R2 or the diameter of the slewing ring is dimensioned such that the lower ends of the rollers R1 and R2 almost touch the upper flange 25 of the winding spool from the outside.

The height of the roller R1 is variable and is adjusted according to the position of the turntable 32 by means of a cam plate 33 or pneumatics. The setting range extends from a minimum height on the line S1, the free end of the roll R1 projecting into the winding area and a maximum height on the line S2, the free end of the roll R1 lying above the upper edge of the upper flange 25. The height of the roller R2 is fixed and dimensioned such that the lower, free end of the roller R2 is approximately flush with the lower edge of the upper flange.

Furthermore, the device 30 for separating scrap, as can be seen in FIG. 9, has a motor 34 for the turntable 32 which is mounted on the upper side of the upper holding device and which drives the turntable 32 with the rollers R1 and R2 via a drive 35 drives.

If an error occurs in the cable K, which has to be removed as scrap from the container, the laying roller 14 of the laying 4 moves from its current winding position Pos.l a so-called scrap position Pos .2 at an approximate height of the lower edge of the scrap disc 31. At the same time, the roll R1 is extended to its maximum length.

When the laying roller 14 reaches the scrap position 2, the slewing ring 32 begins to rotate. The roller R1 pulls an (ascending) loop R1.1, at the same time the laying roller has continued to move to a scrap installation position item 3, which is above the scrap position item 2.

During the rotary movement, the roller R1 pulls back on the line S2 according to the cam disk 33 and releases the loop R1.1 again.

The cable K is now laid on the scrap disc 31 according to an adjustable characteristic. Depending on the length of the scrap, the slewing ring 32 continues to rotate, the roller R2 now pulling a (descending) loop.

At the same time, the laying 4 moves down to the winding position Pos.l, where it was interrupted in the winding pattern, and from there continues the specified winding pattern. The speed differences for winding diameter - flange diameter - and scrap disk diameter are taken into account in a program.

1, 3, 8 and 9 show, the - conical - winding coil runs in the core diameter on the

Scrap disk diameter, just as the winding pattern tends to the scrap disk diameter.

In summary, this method of sorting scrap can also be described as follows. If an error occurs in the winding material, which has to be removed as scrap from the container, the laying moves out of the coil, with a roller system R1 lifting an ascending cable loop over the flange of the winding coil. The installation winds the above-mentioned error on the scrap disc and returns via a descending cable loop and the R2 roller system to the position at which the installation process was interrupted. Here the laying continues to wind the specified winding pattern.

A coil drive 8 is arranged in a direct manner on the lower part of each receiving device, on the output shaft of which a flange plate 97 and a guide disk 98 are fastened. The direct coupling of the coil drive 8 or the direct transmission is particularly quiet.

Fig. 13 shows an alternative drive to a winding spool. In this case, a coil drive 8 'rotated by 90 ° is coupled to a coil station by means of an angular gear, as a result of which lower overall heights can be achieved.

Each flange plate 97 has, concentric to the axis of rotation, a conical elevation 23 which centers the winding spool in a corresponding opening in the lower flange 27. Furthermore, O-rings are provided in the flange plate 97 for receiving the winding spool. The rotational movement is transmitted via W

21st

Friction.

As can be seen in FIG. 2, a gripping device 70, 71, each with a swivel arm 75, 76, is also provided at each winding station for both “right” and “left” rotating winding bobbins. Two gripping brushes 74 are each arranged on the swivel arms 75, 16. In the closed state, these gripping brushes 74 rest against the winding material of a winding spool in such a way that the outer cable end of the cut cable K is prevented from being knocked over.

Furthermore, as can be seen from FIG. 7b, each winding station 101, 102 has the guide disk 98 with a catching device 95, which in this case is equipped with a double catching knife 96 for both winding directions.

These catching devices 95 cooperate to separate the cable K when relocating with capping devices 90 and pressure rollers 94 arranged on the central column 80.

These capping devices 90 are pivotably attached to the (front) sides 85a, 85b of the center column 80 facing the winding spools, as can be clearly seen in FIGS. 7a and b and 10, and each have a support part 91 which can be pivoted through 180 °. At one end there is a lifting roller 92 and at the other end a cut knife 93 for cutting the cable K is arranged. When changing the direction of winding, the cutting device swivels by 180 °.

The pressure rollers 94 are arranged on the longitudinal sides 86a, 86b of the center column, which press the cable K into the respective catch knife of the corresponding catch device 95 when it is moved.

The catching device 95 of the winding station, which is equipped with the empty winding bobbin, or the catch knife provided for the corresponding winding direction, as shown in the illustration according to FIG Cable K and in this case moves it counterclockwise around the empty winding spool. The cable K comes into abutment with the cutting steel 93 of the cutting device 90, through which it is cut off. The cable K now winds around the empty winding spool.

It should be emphasized that these cutting devices 90 make it possible to cut the cable K onto the empty spool at full production speed.

Furthermore, the double winder has a conveyor system 60 which is integrated into the double winder and comprises roller conveyors 61, 62, 63 and chain conveyors 72, 73 in order to achieve fast changing times.

Via a first roller conveyor 61, which, as can be seen from FIG. 2, is arranged along the two winding stations 101, 102, empty winding bobbins S are conveyed into the double winder 100 in accordance with the arrows 103, 104 in order to load the two winding stations 101, 102 .

Two chain conveyors 72 and 73, each of which can be lowered or raised, are arranged at right angles to each other and at a distance from each other between the two winding stations 101, 102. the empty bobbins, in the two winding stations 101, 102 and at the same time the coils wound there, i.e. transport the full bobbins from the two winding stations 101, 102.

In each case an extension of the two chain conveyors 72, 73, a second and third roller conveyor 62, 63 are arranged, which take over the wound winding spools from the chain conveyors 72, 73 and convey the wound winding spools out of the double spool 100 in accordance with the arrows 105, 106.

As FIGS. 1 and 3 clearly show, the chain conveyors 72 and 73 are from a first position or height, a conveying or transport position, to a second position or height, respectively Winding position, lowerable.

The chain conveyors 72, 73 are then lowered as soon as an empty winding spool has reached its winding station or its winding position. As a result of the lowering, the empty winding spool is released from the chain conveyor 72, 73, the empty winding spool is lowered onto the flange plate 97, the spool is stretched between the scrap disk 31 and the flange plate 97 and driven by friction.

Additionally or alternatively, a positive connection between the coil and the flange plate 97 can also be provided here, for example by means of a (driver) pin.

As long as the winding process of a winding spool continues, the chain conveyor 72 or 73 remains in its lowered state. However, as soon as the winding process has ended, the chain conveyor 72, 73 is raised, as a result of which the full winding bobbin is picked up or picked up again by the chain conveyor 72, 73, the full winding bobbin is raised and thus lifted from the bobbin drive and then transported away from the winding station.

The guide disks 98 of the winding stations 101, 102 are shaped accordingly, so that the respective chain conveyor 72, 73 can lift the winding bobbin.

4 shows another embodiment of the double winder 110 with an alternative installation of the integrated conveyor system 64. In this embodiment, the chain conveyor 72 or 73 rotates through the system in each case rotated by 90 °

The double winder is controlled by a control device (not shown). This control device has a program memory in which a program is stored which controls the function. Furthermore, a data memory is provided for the purpose of function control store necessary data, as well as a variety of sensors that record the status of the individual parts of this device. In addition, a variety of electrical and electropneumatic actuators are provided, the actuation depending on the _. Control device output signals takes place.

The function of the double winder, in particular the transfer, is now described in detail, in particular with reference to FIGS. 11 and 12, which illustrate the transfer when winding in a clockwise or counterclockwise direction:

The cable K runs over the take-off pulley Ia, against which it is braced with the flat belt 2, the lifting roller Ib and the dancer rollers 3a 3b into the system, the double winder 100. The dancer rollers 3a, 3b ensure that the cable K essentially always has the same voltage.

The cable K, as can be seen from FIG. 1, is deflected upwards over the rollers 55 via the winding stations 101, 102 and is further fed via the hollow shaft 51 to the rotating union 50 of the laying 4.

Subsequently, the cable K is fed further via the feed rollers 13 and the laying roller 14 to the winding spool S1 or S2 currently to be wound, as indicated in FIG. After the winding direction has been set, the winding spool S1 or S2 is rotated in a direction counterclockwise or clockwise by the motor 8.

The laying device 4 causes the cable K to be placed on the core of the winding spool S1 or S2 in accordance with a predetermined winding characteristic. In the case of a conical winding core, the method as described in EP 334 211 B2 is preferably used for this. The disclosure of this document is included in the present patent application for the purpose of disclosure. Instead of this laying characteristic, a laying characteristic can also be used, in which the winding is applied parallel to the axis of rotation of the winding spool, which is possible both with a conically shaped winding spool and with a cylindrical winding spool.

During the winding process it is possible to reject defective winding material or scrap using the scrap disc.

^■ The winding process is continued with the specified characteristic until a predetermined degree of filling of the winding spool S1 or S2 to be wound is reached.

As soon as this predetermined degree of filling is reached, the control device outputs a signal by which the transfer from the full coil to the empty coil, i.e. is introduced from the coil S1 to the coil S2 or vice versa (see FIGS. 11 and 12).

During the relocation, as shown in FIGS. 11 and 12, the relocation 4 - depending on the winding direction - moves clockwise or counterclockwise along the elliptical path predetermined by the rail system around the two winding stations 101, 102, the cable K from the full spool placed on the empty spool and cut.

In FIG. 11, in the view of the winding station 100, the transfer for winding the coils S1 and S2 is shown in a clockwise direction. Fig. 12 shows this for winding counterclockwise.

As can be seen in Fig. IIa (Fig.11, winding clockwise), the laying 4, which is in Pos.l, winds the coil S1 until the predetermined degree of filling is reached and the rerouting is initiated.

Laying 4 now moves from position 1 in the direction of the arrow Item 3, the cable K taking the course indicated by the dash-dotted line. At the same time, the coil S2 begins to turn.

The cable K, as is known in principle from the prior art, is then pressed down by the pressure roller 94, caught by the catch knife of the catch device of the coil S2 and cut by the cutting device 90.

The wound coil S1 is then stopped and exchanged for an empty coil.

The laying 4 moves, with simultaneous laying of the cable, as can be seen from FIG. IIb, from the item 3 in the direction of the arrow to the item 4 and moves the cable K to the coil S2.

While the coil S2 is being wound from the laying position, item 4, it is possible, as illustrated in FIG. IIb, to separate out scrap by means of the scrap disc or the corresponding mechanism.

As soon as the predetermined degree of filling has been reached for coil S2, as shown in FIG. 11c, the next transfer of the cable from coil S2 to coil S1 takes place, corresponding to the previous one.

For this purpose, the laying 4 moves from item 4 in the direction of the arrow to item 6, the cable K again taking the course indicated by the dash-dotted line. At the same time in this case the coil S1 begins to rotate.

The cable K is then pressed down here again by the pressure roller 94, caught by the catch knife of the catch device of the coil S1 and cut by the cutting device 90.

Then the wound coil S2 in this case stopped and exchanged for an empty spool.

The laying 4, as can be seen from FIG. Hd, moves from the position 6 in the direction of the arrow to the position 1 and moves the cable K to the coil S1.

While the coil S1 is being wound from the laying position Pos.l, it is again possible to separate scrap by means of the scrap disc or the corresponding mechanism.

As can be seen in FIG. 12a (FIG. 12, winding counterclockwise), the laying 4, which is in position 2, winds the coil S2 until the predetermined degree of filling is reached and the relocation is initiated.

The laying 4 now moves from item 2 in the direction of the arrow to item 6, the cable K taking the course indicated by the dash-dotted line. At the same time, the coil S1 begins to rotate.

The cable K is then, as is known in principle from the prior art, pressed down by the pressure roller 94, caught by the catch knife of the catch device of the coil S1 and cut by the cutting device 90.

The wound coil S2 is then stopped and replaced with an empty coil.

The laying 4, as can be seen from FIG. 12b, moves from the position 6 in the direction of the arrow to the position 5 and places the cable K on the coil S1.

While the coil S1 is being wound from the laying position pos. 5, it is possible, as illustrated in FIG. 12b, to separate out scrap by means of the scrap disc or the corresponding mechanism. As soon as the predetermined degree of filling is reached for the coil S1, the next transfer of the cable from the coil S1 to the coil S2 takes place, as shown in FIG. 12c, in accordance with the previous one.

For this purpose, the laying 4 moves from item 5 in the direction of the arrow to item 3, the cable K again taking the course indicated by the dash-dotted line. At the same time, the coil S2 begins to rotate in this case.

The cable K is then pressed down again here by the pressure roller 94, caught by the catch knife of the catch device of the coil S2 and cut by the cutting device 90.

In this case, the wound coil S1 is then stopped and exchanged for an empty coil.

The laying 4, as can be seen from Fig.l2d, moves from position 3 in the direction of the arrow to position 2 and places the cable K on the coil S2.

While the coil S2 is being wound from the laying position, item 2, it is again possible to separate scrap by means of the scrap disc or the corresponding mechanism.

The second exemplary embodiment of the invention according to FIG. 14 is a winder 200 in a horizontal construction, in which the winding station is arranged horizontally for winding a - horizontally - aligned reel S1.

Here too, as shown in FIG. 14, the device for separating defective winding material 30 is provided. This also corresponds in the case of horizontal alignment in structure and function of the device described above for separating defective winding material 30 in the vertical 2nd

Alignment. The same reference numerals are assigned accordingly.

The - in the case of horizontal alignment - the right receiving part of the winder here, as shown in FIG. 14, has on its side facing the winding reel S1 the device 30 for rejecting faulty cable pieces or scrap or the scrap disc 31.

Here, too, the process for separating scrap can be described as shown. If an error occurs in the material to be wound, which has to be removed as scrap from the container, the laying (Fig. 14 shows the roller 14 in pos. 1 and pos. 3) moves out of the coil, whereby the roller system R1 has an ascending cable loop lifts over the flange of the winding spool. The installation winds the said error on the scrap disc and returns via a descending cable loop and the R2 roller system to the position at which the installation process was interrupted. Here the laying continues to wind the specified winding pattern.

As FIG. 14 further shows, here - comparable to FIG. 13 - the winding spool is driven by means of a spool drive 8 ″ rotated by 90 ° (with respect to the spool axis) and an angular gear 9 ′.
