description

The present invention relates to a conveying device for supplying a machine for yarn processing, in particular for supplying a spinning knitting machine to equip holding positions of the machine in use with yarn-loaded spindles or coils and to remove emptied spindles or spools from the mounting locations, said Conveying device guide rails or guide rail strands and thereto movably mounted holder for holding in each case comprises at least one spindle.

Brackets of such a machine are here the appropriate places where spindles are plugged or positioned so that during operation of the machine yarn material can be unwound from the spindle and fed to the yarn processing process.

The invention also relates to a production device comprising a plurality of such machines for yarn processing and at least one corresponding conveyor device according to the invention. The present invention also relates to a method of feeding a yarn processing machine using a machine

corresponding conveyor device according to the invention and / or a corresponding production device according to the invention. The present invention is particularly advantageous in the

Use for supplying a spinning knitting machine.

Spinning knitting machines are a development of recent years and are characterized by the fact that these machines, which generally work as circular knitting machines, do not turn knitwear as was customary in the past Form yarns which are provided on relatively spiked cheeses.

But spinning machines use roving, sliver, Flyerlunte or similar fiber material, from which usually only the yarn for the cheeses is produced and rotated, and use this roving directly for the production of textile material. As a result, a processing step in the textile production can be saved. This roving is provided on so-called roving bobbins for a relatively small amount or length per flyer bobbin, at least in comparison to the amount of twisted yarn that was available and provided on individual packages in previous systems. Thus, a much larger number of flyer bobbins must be provided for such a spinning machine than for previous machine packages had to be provided with twisted yarn, while the flyer bobbins compared to the cheeses generally have a significantly smaller thickness and a significantly lower weight.

Since the shape and size of the bobbins with which a machine for yarn processing must be equipped has thus changed and at the same time brought a considerably larger number of bobbins to a machine and the machine must be equipped to produce the same amount of textile, can previous Systems for supplying machines with spools or spindles can not be used without incurring disadvantages. Because these conventional systems are designed to provide a significantly smaller number of coils that would be insufficient for a sufficient supply of spinning machines.

Although the present invention thus aims primarily at the supply of spinning knitting machines, the subject matter and the method of the present invention is, of course, applicable to any machine in which holders are fitted with spindles or bobbins have to. For further details regarding spinning knitting machines, reference is made to DE 10 2007 004 441 A1, DE 10 2008 008 210 A1, DE 10 2008 031 130 A1, DE 10 2010 022 339 A1, DE 10 2013 104 193 A1, DE 10 Reference is made to DE 103 2015 738 A1, DE 10 2015 102 266 A1 and DE 10 2015 102 285 A1 and the publications cited therein.

So far, it is common in spinning knitting machines to store new roving in boxes next to the machine or in a warehouse. They must be manually removed from the boxes and attached to the suspensions when a spool has run empty or the machine needs to be refitted. The cartons are generally placed manually or by machine-driven vehicle in the vicinity of the machine.

The empty roving bobbins are removed by hand from the suspension or the mounting space and replaced by a full bobbin. In this case, the beginning of the fiber material or roving is also manually threaded into the corresponding elements of the spinning machine.

Since such spinning knitting machines generally have a plurality of support locations, the corresponding operator must either move each carton to each storage location and then perform the replacement operation, or the carton is placed in a location adjacent to the machine and the operator each leaves the carton each individual support slot and back again to bring each one full spool back to the bracket space and an empty spool back away. Although the operator may carry several full or populated bobbins, but generally not so many, that with only one removal from the carton and only a drain of the entire circumference of the machine and collecting all empty bobbins doing a complete replacement of all coils to be replaced can be done.

Thus, the operator has to travel many distances several times and stoop several times, both in terms of workload and

Productivity and health of the operator is unfavorable. Furthermore, the mounting locations or suspensions are generally at or above the head height of an operator, which, in combination with the necessary bending over to the carton, is generally unfavorable.

From DE 10 2015 102 267 A1, as a solution to this problem, the proposal is known to provide a machine-driven loading device which is movable along at least one predetermined path and is suitable to remove roving bobbins from conveyors, to move to a corresponding mounting position and there to use automatically. In this case, the path or the travel path can also be purely virtual, for example that of a mobile robot arm

Gripper swept path. Admittedly, the above-mentioned difficulties are essentially overcome, since above all the corresponding burdens for one

Operator are avoided. However, in this solution are new

Problems have arisen, for example, that construction and control of corresponding robot arms or comparable systems are technically more expensive and costly than expected or hardly feasible. Furthermore, the corresponding technical and

Controlled complex assembly equipment to a critical bottleneck, because in technical problems or failures then holders of machines concerned can no longer be properly fitted, which may be due to the failure of a single one of several used for supplying a machine

Equipment is a failure of the entire machine is the result. Because for the uniform textile production is the regular

Reinstallation of all mounting positions required.

This problem could be overcome in this solution by each holder slot can be approached by several equipment, but this increases the cost in addition. Thus, while this proposed solution solves some of the existing problems, it does but to new difficulties whose seemingly obvious solutions in turn lead to a satisfactory result.

Object of the present invention is therefore to provide a way to provide a machine for yarn processing, so to equip their support slots with spools loaded with yarn and remove emptied coils from there that is effective and easy to use, and in particular both the problems of the conventional Systems as well as the problems of the solutions proposed so far avoids.

This object is achieved by a conveyor device according to claim 1, a production device according to claim 15 and a method according to claim 18. Advantageous embodiments and embodiments are the subject of the dependent claims.

The conveyor device according to the invention is characterized in that at least two guide rail strands adjacent to

Holding sites of the machine to be supplied and preferably run close to each other, wherein with respect to each mounting place the

the nearest position of the respective guide rail track or the area around this position around a handling area of the

Guide rail strand for the corresponding mounting position, wherein the distance of each handling area from the associated mounting space is less than two meters, in particular less than 1, 5 m, in particular less than 1 m and more preferably less than 0.5 m, so that for each of the mounting positions at least one associated standing position exists, from which a positioned there operator average

Adult size both a spindle, which is supported on a holder mounted in the associated handling area, as well as a held in the mounting position spindle can handle without leaving the stance position.

This offers the advantage of having two appropriately running

Guide rail strands always on at least one of Guide rail strands each a stocked or roving provided coil in association with the respective support slot can be kept and the operator just has to go to the appropriate position of a mounting bracket to stocking and from there without having to travel a considerable way to seize the assembled coil - And position on the appropriate bracket without having to bend over, for example.

Accordingly, it is also preferred that the guide rails extend at a height which corresponds approximately to the height of the mounting positions, preferably less than 0.5 m difference, since then the operator can each upwards or can be oriented upward to both the Coils on the holders of the guide rail strands as well as the coils on the

To achieve mounting positions of the machine. This will be

especially back complaints significantly reduced compared to the previous solution.

In this case, the term "standing position" is to be understood as meaning a small area from which both the coils located on the holders of the guide rail strands and the holding stations and the coils located there can be reached, such a region being particularly preferably smaller than a circle with a diameter of 1 m and more preferably smaller than a circle of 0.5 m in diameter, so that the operator has to make at most one or two small steps in order to be able to reach the bobbins at the holding places or the holders with the hands.

According to the invention, it is preferable for each of the at least two guide rail strands to extend in such a way that each one of them has its own

Holding space of the spinning knitting machine associated handling stations each have to the corresponding holding space a distance in the above manner. This means in particular that the conveying device according to the invention is designed and arranged around the machine for yarn processing, that there is no mounting space to which only a corresponding handling area of a

Guide rail strand has a distance in the manner described and to which a corresponding handling area of the second

Guide rail strand has a distance greater than in the manner described. However, it is particularly preferred that the guide rail strands run so close to the associated mounting position that an operator can reach both the held on the holders coils and the coils located at the mounting positions with suitable positioning at the standing position without walking of the feet. This leads to a particularly quick and simple assembly process, since only the operator has to move to the appropriate standing position and then perform a handling process or assembly operation essentially purely with movements of the upper body or the arms.

The fact that the operator has to carry bobbins in cartons or by hand over distances greater than 2 m is completely avoided by the present invention in any case. Compared to the above-mentioned known automated system for the supply of spinning knitting machines, the present invention offers the great advantage that no complex technical systems, such as robot arms, must be used, whereby both the cost and the risk of failure are significantly reduced.

This is especially true, as appropriate guide rails and

corresponding holders, which are also known as coil trains, are technically extremely simple. Examples of the construction of such guide rails with coil trains are known from EP 1 568 805 A2 and EP 1 568 806 A2, the contents of which are hereby incorporated by reference.

In particular, the guide rails of the present invention and the holders of the present invention may be of the same type as the

Guide rails or coil conveyors and the holder or

Spooling trains of said documents. In this case, the handling possible for the operator from the standing position preferably comprises:

 - Removing a spool stocked with yarn from a holder;

 - Inserting a spool loaded with yarn in the associated

 Place holder;

 - Removing an emptied coil from a mounting location; and

- Inserting an emptied coil in a holder. These operations are executable for an operator from the standing position when the distance between the handling area and the associated mounting space is small enough.

It should be noted in general that the distances mentioned are exemplary for average size operators, ie persons with a height in the range of 1, 70 m to 1, 80 m and usual arm lengths. Because body sizes in some regions of the world

distinguish, is provided according to the invention, if necessary, the said dimensions for the distance corresponding to the body sizes of the available operating personnel to adapt so that appropriate

 Operators of the associated standing position without leaving the stance position handling of coils to the

 Guide rail strands or coils can perform on the support space.

Also, it is not excluded that more than one or overlapping stand positions exist with respect to a mounting location, namely, when the distance between the handling area and associated mounting space is correspondingly small, so that there are more places from which handling area and mounting space reached at usual arm lengths are.

Furthermore, a correspondingly small distance may also be advantageous because then from the position of standing a larger area of the Guide rail strands can be reached, so even on coils

can be accessed, the holder is not located directly at the nearest location of the guide rail track. According to the invention, at least two guide rail strands are provided, since this makes it possible to always have at least one

Guide rail train with populated coils ready to hold while empty coils on the other guide rail track straight away and populated coils are replaced as a replacement. Thereby are

Delays in loading the mounting slots of the machine, because on the holders of the guide rail strands just in the handling area no populated coils are available, avoidable.

Depending on the yarn requirement of the machine and storage, it may also be advantageous in particular, more than two corresponding

 Provide guide rail strands, as additional

Guide rail strands simplify it accordingly, always keep ready in at least one handling area of a mounting place a populated coil.

In one embodiment, holders can be used, on which more than one coil can be supported. In particular, those holders come into question, which lined up along the course direction can support at least two coils.

In particular, such a holder for holding a plurality of coils along the running direction of a guide rail track may also have such a length as to extend from one handling area to another handling area and hold a plurality of bobbins.

A preferred embodiment is in particular that such a holder has a length such that it extends along a

Guide rail strand to all handling areas of the machine extends. As a result, by retracting or supplying this one holder on the corresponding guide rail track for all

Mounts of the machine are provided a sufficient number of equipped spindles. Once all of these have been reversed with empty bobbins of the holder slots, the entire holder can be removed again to remove all empty bobbins accordingly.

The optimal length of corresponding holder from a length for holding only one coil to a length to reach all

Handling areas of the machine at the same time depend on the size and shape of the machine, number of mounting positions and exact course of the guide rail strands adjacent to these and the storage and transport system which supplies the assembled spindles to the guide rail tracks adjacent to the machine.

The at least two guide rail strands are preferably via to the guide rail strands similar transport rails with a

Buffer bearing connected to holder. This buffer storage can have corresponding connections via transport rails to guide rail strands on different machines, so that a certain amount of stocked coils are temporarily stored in this buffer storage and distributed to the different machines as needed. By a suitable size of the buffer storage can be appropriate bottlenecks at a particularly high consumption in one machine and very low consumption of the other machines well avoided.

Preferably, two or possibly more than two of the at least two guide rail strands are connected to the same via the same transport rail

Buffer store connected, with a corresponding switch for each distribution is provided on the different guide rail strands.

Similarly, an empty buffer storage may be provided for holders with emptied coils that over to the guide rail strands similar removal rails is connected to the guide rail strands.

This ensures that there are no jams when once many emptied coils of guide rails of different machines must be carried away simultaneously.

It can also be designed sufficiently large buffer storage and with a corresponding number of parallel rails so that it serves both as a buffer storage and as an empty buffer storage.

The exact geometric course of at least two

Guide rail strands in the vicinity of the machine is mainly based on the geometric shape of the machine and in particular the geometric arrangement of their mounting positions. In circular knitting machines, the corresponding guide rail strands or at least some of them preferably extend on circular paths or

partially circular tracks around a certain angular range around the machine.

It is particularly preferred that the circular path extends completely or almost completely around the machine, since the

Support slots of a circular knitting machine are generally arranged in the form of a circle. In this case, a complete circular extent over the entire 360 ° is not absolutely necessary, since only for each support location a corresponding handling area must be provided on each guide rail track, so that between a first provided by a guide rail line handling area on a seen along the first circle

Supporting space and along the circle last bracket space a certain gap may be present in the circle formed by this guide rail track. However, there are also alternative forms conceivable, both at

Circular knitting machines as well as machines for yarn processing with a different shape. For example, one of the at least two

Guide rail strands also comprise a plurality of straight sections, in particular also four straight sections, so that in plan view a nearly rectangular or square course of

Guide rails forms, except for curves at the "corners" whose minimum size is determined by the maximum possible with the guide rail strands bending.

It is also conceivable that different pairs of guide rails or larger groups of guide rail strands are provided for different sections of the machine for yarn processing. For example, that in a circular knitting machine in plan view two

Guide rail strands as a semicircle on one side of the

Circular knitting machine and two further guide rail strands as

Semicircle on the other side of the circular knitting machine.

According to the invention, it is mandatory with regard to such others

Embodiments only that at least two guide rail strands are adjacent to each support location so that the distance of the corresponding handling area of the support space is less than two meters or so small that an associated standing position exists as previously described.

It is in principle even technically possible that corresponding holders are manually moved along the guide rail strands, but it is of course preferred to provide a corresponding drive system or a corresponding control device which is designed or programmed so that holders with populated coils so

Handling areas are supplied and holder with emptied coils are led away from the handling areas that at any time always at least one loaded coil is supported in each handling area in a holder. Preferably, the conveying device according to the invention comprises sensor and / or signaling means for determining whether for the operation of the machine, a mounting space is equipped with a populated coil and / or whether a located on a support station coil is to remove and / or emptied. Thus, a corresponding message system is operable, which indicates to the operator or operators when a coil is to be replaced at a certain mounting location. Alternatively or additionally, such systems may also be provided as part of the machine.

The guide rail strands can also basically run so that they intersect in plan view with other guide rail strands or with itself. For that, the appropriate

 Guide rail strands at different heights with sufficient distance with respect to the coils to be held or it may be provided appropriate switches to form real intersections. This is particularly realizable that two

Guide rail strands as a complete circle around one

 Circular knitting machine run around and are coupled via corresponding switches with transport rails.

Preferably, the standing position is at the same height as a floor of the

Machine; So that, for example, guide rail strands and

Bracket locations are at such a height that the

Stand position is located on the floor of the corresponding workshop. Then the operator just has to reach the appropriate area, can grab upwards accordingly (preferably, the rails then run so above that the operators can pass underneath) and perform appropriate handling.

Alternatively, the standing position can also be increased relative to the floor of the machine, so that at corresponding position positions podiums or Similar increases are provided to which the operator to

Handling rises. Alternatively, the operators can also

Stool, stool or small ladders carry to reach the appropriate height well. This can be advantageous since, with correspondingly long coils, the guide rail strands have to be guided sufficiently high so that the operators can easily pass underneath in order to reach the machines. Furthermore, many yarn processing machines also have mounting stations at a height that can not be reached by an operator standing at the level of the floor of the machine.

According to the invention, a production device comprising a plurality of yarn processing machines and at least one

proposed conveyor device according to the invention.

In principle, a separate conveyor device according to the invention can be installed for each machine, so that each machine of the

Production facility over a complete and only for

Supply this machine serving guide rail set features.

Alternatively, it can also be provided that the at least two

Guide rail strands of the conveyor device according to the invention or of several conveying devices according to the invention run so that run for each mounting location of each machine at least two guide rail strands adjacent to the features of the invention or alternatively for at least two support slots of different machines at least two guide rail strands correspondingly adjacent, but also for at least one Holding space of another machine accordingly adjacent.

In an arrangement of a larger number of machines, it is thus possible, the conveyor device according to the invention or more

According to the invention to design conveyors and the

Guide rail strands run suitably that pairs or groups of guide rail strands provide handling areas for mounts of various machines. As a result, the number of required guide rail strands can be kept low. In particular, when arranging several machines,

In particular circular knitting machines, in a uniform rectangular pattern in each case at least two guide rail strands run between adjacent machines and by appropriate

Blade usage at intersections in top view a grid-like

Guide rail network for the formation of the invention

Be formed conveyor.

Corresponding sensor and / or signal means may also be provided for the production facility as a whole in order to register the need for handling at a specific mounting location and / or to indicate to operators.

The inventive method for supplying a machine for yarn processing, in particular a spinning knitting machine to order

In operation, machine mounts fitted with spools loaded with yarn, and to remove emptied spools from the mounts, comprise at least the following steps:

 Providing a conveyor device according to the invention or

 Providing a production device according to the invention;

 - Method of holders with equipped populated coils in a handling area;

 - Positioning an operator on one of the at least one

 associated standing position; and

 - Performing at least one of the following handling steps by the operator without leaving the standing position:

 a) removal of a yarn-loaded bobbin from a holder in

 Handling area;

b) inserting a spool loaded with yarn in a mounting position; c) removal of a spent coil from a mounting location;

 and or

 d) inserting a spent coil into a holder in

 Handling area.

This makes it easy and with little technical and low

Personnel expenses while protecting the health of the

Provide staff in particular a spinning machine with roving in sufficient numbers.

The method of the invention may further comprise one or more of the following steps:

 - Determining a equipped with a populated coil

 Bracket space and / or determining one at a

 Bracket located and to be disposed of, in particular emptied coil;

 - Positioning an operator on a corresponding

 Stance position determined in the previous step;

 - Leading away a holder with at least one, preferably only

 emptied coil from a handling area; and or

 - Supplying a holder with at least one, preferably only

 equipped coil in a handling area into it.

Preference is given to the holder before, after and / or during the

Handling steps such that when the operator leaves the stance, again at least one spool loaded with yarn and held in a holder in the handling area. This ensures that at any time without loss of time, the operator or another operator re-equipping the corresponding

Holding space can make.

During the method according to the invention, the holders are preferably moved in such a way that at least one spool, equipped with yarn and held in a holder, always comes from the standing position for the spool Operator is reachable. This means preferably that from each stand position always a corresponding coil can be reached, so any time each bracket can be re-equipped accordingly by an operator.

The present invention will be described below with reference to the accompanying figures.

They show:

Conveying device in which two a spinning frame almost completely circular surrounding Guide rail strands are connected to each other via an external loop; and

Figure 7 shows an embodiment of the invention

 Conveying device, which dispenses with a switch and in which a single rail in spiral form around the

 Spinning knitting machine is guided to form at least two guide rail strands. The conveying device 1 according to the invention shown in FIG

 Supplying a circular spinning-knitting machine 40 to load holding stations 42 of the machine 40 in operation with yarn-loaded bobbins and to remove emptied bobbins from the holding stations 42 comprises almost a complete circle around the spinning-knitting machine 40

running guide rails 10 or guide rail strands 10.

Along these at least two guide rail strands 10 are located corresponding to each support location 42 nearest positions 14 and handling areas 14 of the guide rail strands 10. In this case, the guide rail strands 10 are such that the

 Handling areas 14 of the respective mounting space 42 have a maximum distance 16, which is smaller than 2 m and in concrete

Embodiment also smaller than 1, 5 m. This means, in particular, that at each mounting location 42, the closest point of each guide rail track 10 has a distance 16 of less than 2 m or 1.5 m to the mounting location 42.

This results in at least one for each bracket space 42

Standing position 18, from which an operator without walking of the feet both coils (not shown in Figure 1) in the handling area 14 of each guide rail track 10 and the coil on

Holding space 42 can reach with your hands. It can not be seen in Figure 1 due to the line of sight

Standing positions 18 are formed as pedestals 18, since both support locations 42 and guide rail strands 10 extend at a corresponding height above the floor.

Also shown schematically is an operator 100, who is currently standing on a corresponding concealed pedestal 18, from there to the adjacent mounting space 42 and the adjacent

Handling areas 14 of the guide rail strands 10 to access. In this case, the operator 100 due to the sufficiently small distance 16 of the corresponding handling areas 14 to the corresponding mounting location 42 from the pedestal 18 both on the located on the support slot 42 coil and on in the

Handling areas 14 in not shown holders salientierten coils access, without leaving the standing position or the pedestal 18.

 In particular, in the present case, the distance 16 is so small that the feet of the operator 100 for a conversion of coils from the at the

Guide rail strands located holders to the support slot 42 or vice versa need not be moved in steps.

If the two guide rail strands 10 are equipped appropriately equipped holders equipped with spools, the operator 100 can equip each bracket space 42 as required or replace coils located there without having to carry coils with them and without bending over.

As an alternative to the pedestals 18, the operator 100 may also carry a suitable increase, for example a small stepladder or the like, and accordingly set up always at the corresponding standing position 18 in order to move from this elevation to the respective one

 Support slot 42 and the respective handling areas 14 to access.

The guide rail strands are via a switch 22 with a

Transport rail 20 connected in the following to a not shown Buffer bearing for holder leads. Such a buffer storage may include one or more corresponding switches similar to the switch 22, which allows access to a plurality of, for example, parallel rails (similar to the area to the left of the switch 22) for carrying holders or groups of holders on such storage or buffer rails equipped coils or emptied coils to position. From there or there you can as needed to or from the guide rail strands 10 or adjacent to other machines positioned similar guide rail strands 10 are supplied or removed.

Figures 2 and 3 show other possibilities of the course of the at least two guide rail strands 10. As shown in Figure 2 and Figure 3

As shown in FIG. 1, the course of the two guide rail strands 10 may also be other than circular to form respective handling areas 14, since only the distance from a support location 42 to the nearest points of the guide rail strands 10 must be low enough and thus in areas in which no mounting space 42 is provided, the distance between the guide rail strands 10 can also be greater. However, in many machines, even circular knitting machines, even with arranged along the entire circular circumference mounting slots 42 a sufficiently small distance 16 all

Handling areas 14 are often achieved with other than a circular course of the guide rail strands 10.

As shown in Figure 3, a plurality of separate pairs of guide rail strands 10 or groups of

Guide rail strands 10 (according to the invention can also be provided more than two corresponding guide rail strands) are used for the supply or training of corresponding handling areas 14 of different mounting locations 42. Turnouts 22, which in turn produce a connection to further transport rails (not shown) and, if appropriate, corresponding buffer bearings, are also indicated in both FIGS. 2 and 3. In FIG. 4, a course similar to that of FIG. 1 is again shown in FIG

Guide rail strands 10 shown. Again, the two are

Guide rail strands 10 via a switch 22 with a

Transport rail 20 connected. For ease of illustration, the corresponding machine to be supplied for yarn processing is not shown.

As shown in FIG. 4, the inner track rail 10 can be fully fitted with brackets to form a more or less continuous row of bobbins 50, thereby providing at least a plurality of cradles 42 along the circumference of the yarn processing machine for each cradle a standing position exists, from which access to corresponding coils 50 is possible.

At the same time, the outer guide rail line 10 is empty and, while the located on the inner guide rail line 10 coils 50 for the supply and supply of the machine for

 Garnbearbeitung be used, equipped accordingly with holders or ride on, bring the new coils.

This can ensure that always coils are available for equipping the mounting positions.

It can optionally by appropriate signal light or

Indication of the operator to be pointed out, from which guide rail strand 10 are just remove coils so that first a guide rail track 10 is emptied or provided with emptied coils, which are to be led away again first. This will then stand during the exchange of these holders on the former guide rail track 10 still populated coils on the other guide rail track available. FIG. 5 shows the situation opposite to FIG. 4 with a similar one

Guide rail arrangement, in which just the outer

Guide rail strand 10 is just equipped with coils 50 and corresponding coils 50 holders halter holding, while the inner guide rail line 10 is empty, since the corresponding holder are driven straight along the further course of the transport rail 20 from or to a buffer storage to empty Spools to bring away or brought populated coils.

A very interesting and advantageous embodiment of the invention is illustrated in FIG. In this exemplary embodiment, two guide rail strands 10 surrounding a spinning-knitting machine 40 almost completely preferably along a circle are connected to one another via an external loop 60. Such a guide rail architecture allows the supply and removal of preferably to support trains

combined holders with coils 50 to the spinning machine 40 toward or away from this without reversing the direction of the trains or holders in their transport movement. In particular, such allows

Guide rail architecture the realization of an endless track in which the two rail tracks 10 are integrated. For such a configuration, the inlet section 62 shown in FIG. 6 and the outlet section 64 shown in FIG. 6 can be connected to one another in a manner not shown, for example in a coil exchange bearing, so that in principle an operation of the conveying device with a single row of holders for Coils are possible, which without reversal in the

Continuous operation rotates.

In Figure 7, an embodiment without switch 22 and without external loop 60 is shown. In this case, a single rail in a spiral-like shape is guided around the spinning-knitting machine 40 several times such that the rail forms at least two guide rail strands 10 adjacent to the mounting locations 42. Since these guide rail strands 10 are substantially the same as in the embodiment in Figure 1 the embodiment corresponds apart from the absence of the switch 22 and the spiral or spiral-like track course the

Embodiment of Figure 1. The advantage of this embodiment is that by dispensing with the switch 22, the overall construction is cheaper and technically easier; However, it is disadvantageous that only the outermost retaining cable or the outermost holders can be easily replaced. On the other hand, for retaining straps lying on the inside, in general, any further outwardly lying retaining pull must be moved. Preferably, for a corresponding embodiment, generally one and only one retaining cable extending along the majority of the spiral would be used.
