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 for supplying a machine for yarn processing using a corresponding conveyor device according to the invention and / or a corresponding production device according to the invention.

The present invention is particularly advantageous when used to supply 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 form knitwear, as was customary in the past, from twisted 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, however, the object or the method of the present invention is, of course, applicable to any machine in which holder spaces have to be equipped with spindles or bobbins. For further details regarding spinning knitting machines is on the DE 10 2007 004 441 A1 , the DE 10 2008 008 210 A1 , the DE 10 2008 031 130 A1 , the DE 10 2010 022 339 A1 , the DE 10 2013 104 193 A1 , the DE 10 2013 103 738 A1 , the DE 10 2015 102 266 A1 and the DE 10 2015 102 285 A1 and the references 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 mounting locations, the corresponding operator must either move or move a respective board to each mounting location and then perform the replacement operation or the board is stored in one location placed adjacent to the machine and the operator each goes from the carton to each individual holding place and back again to take away a full bobbin from the holding place and an empty bobbin. 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, which is unfavorable both in terms of workload and productivity and health of the operator.

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 the DE 10 2015 102 267 A1 is known as a solution to this problem, the proposal 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 bracket space and use it automatically. In this case, the path or the travel path can also be purely virtual, for example the path swept by a movable robot arm with a gripper device.

Although the above-mentioned difficulties are thus essentially overcome, since above all corresponding burdens for an operator are avoided. However, in this solution, new problems have occurred, for example, that construction and control of corresponding robot arms or similar systems are technically and costly ago than expected or hardly feasible. Furthermore, this makes the corresponding technically and control 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 possibly due to the failure of a single of several used for supplying a machine equipment a failure the whole machine is the result. After all, regular replenishment of all mounting positions is necessary for uniform textile production.

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 leads to new difficulties whose seemingly obvious solutions in turn do not lead to satisfactory results.

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 conveying device according to the invention is characterized in that at least two guide rail strands adjacent to the mounting positions of the machine to be supplied and preferably close to each other, wherein with respect to each support location, the nearest position of the respective guide rail strand or the area around this position around a handling area of the guide rail strand for the corresponding mounting location is, 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 holder places at least one associated Standing position exists, from there a positioned there operator average adult size both a spindle which is mounted on a holder mounted in the associated handling area, as well as a in the Halterungsplat z can handle supported spindle without leaving the stance position.

This offers the advantage that by two correspondingly extending guide rail strands always on at least one of the guide rail strands each populated or roving provided coil in association with the respective support slot can be kept and the operator just has to go to the corresponding standing position of a mounting space to be populated and from there without having to travel a considerable distance, the seize equipped coil and position it 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 To achieve coils on the holders of the guide rail strands and the coils at the mounting positions of the machine. As a result, in particular back complaints are significantly reduced compared to the previous solution.

In this case, "stand 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 mounting positions and the coils located there can be reached. Such a region is particularly preferably smaller than a circle with a diameter of 1 m, and more preferably smaller than a circle with a diameter of 0.5 m, so that the operator must make at most one or two small steps in order to apply the hands to the respective coils To reach holding places or the holders.

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, since corresponding guide rails and corresponding holders, which are also known as spool trains, are technically extremely simple. Examples of the structure of such guide rails with coil trains are from the EP 1 568 805 A2 and the EP 1 568 806 A2 known, 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 and the bobbins of said documents.

• - Entnahme einer mit Garn bestückten Spule aus einem Halter;
• - Einsetzen einer mit Garn bestückten Spule in den zugehörigen Halterungsplatz;
• - Entnahme einer geleerten Spule aus einem Halterungsplatz; und
• - Einsetzen einer geleerten Spule in einen Halter.

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 mounting space;
• - 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. Since body sizes differ in some regions of the world, it is provided according to the invention, if necessary, to adapt the dimensions mentioned for the distance corresponding to the body sizes of the available operating personnel such that corresponding operators move from the associated standing position without leaving the standing position to handling coils can perform the guide rail strands or coils 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, since then a larger area of the guide rail strands can be reached from the standing position, so that coils can also be accessed, their holders 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 strand with equipped coils, while empty coils are guided away on the other guide rail strand and populated coils are guided as replacement. As a result, delays in equipping 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 to provide more than two corresponding guide rail strands, since additional guide rail strands make it easier to always have a stocked spool in at least one handling area of a mounting place.

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 a length such that it extends from one handling area to another handling area and holds 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 track to all handling areas of the machine. As a result, a sufficient number of fitted spindles can be made available by retracting or feeding this one holder onto the corresponding guide rail track for all mounting positions of the machine. 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 to support only a coil to a length to reach all handling areas of the machine simultaneously depends on the size and shape of the machine, number of mounting positions and exact course of the guide rail strands adjacent to them and the storage and Transport system, which supplies the equipped spindles to the running adjacent to the machine guide rail strands.

The at least two guide rail strands are preferably connected to the guide rail strands similar transport rails with a buffer storage for holders. 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 buffer bearing via the same transport rail, a corresponding switch being provided for the respective distribution onto the different guide rail strands.

Similarly, an empty buffer storage for holders with emptied coils may be provided, which is connected to the guide rail strands similar Abtransportschienen with 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 the at least two guide rail strands in the vicinity of the machine depends primarily 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 run on circular paths or partially circular paths 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 strand, so that between a first provided by a guide rail line handling area on a seen along the circle first support slot and the along the circle last bracket space a certain gap may be present in the circle formed by this guide rail track.

However, alternative forms are also conceivable, both in circular knitting machines and in machines for yarn processing with a different shape. For example, one of the at least two guide rail strands may also comprise a plurality of straight stretches, so that a nearly rectangular or square course of the guide rail strands is formed in plan view, apart from curves at the "corners", the minimum dimension of which with the guide rail strands maximum possible bending is determined.

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, in a circular knitting machine in plan view two guide rail strands run as a semicircle on one side of the circular knitting machine and two further guide rail strands as a semicircle on the other side of the circular knitting machine.

According to the invention, with regard to such other embodiments, it is only necessary that at least two guide rail strands extend adjacent to each support location so that the distance of the corresponding handling area from the support location is less than two meters or so small that an associated standing position exists as described above.

In principle, it is even technically possible for corresponding holders to be displaced by hand along the guide rail strands, but it is naturally preferable to provide a corresponding drive system or a corresponding control device which is designed or programmed in such a way that holders with populated coils thus cover the handling areas be supplied and holder with emptied coils are guided 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 this purpose, the corresponding guide rail strands can run at a different height with sufficient spacing with respect to the coils to be held, or corresponding switches can be provided for the formation of real intersections. This is particularly realizable that two guide rail strands run as a complete circle around a circular knitting machine 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 mounting places are at such a height that the standing 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 in relation to the floor of the machine, so that pedestals or similar elevations are provided at corresponding standing positions, on which the operator stands out for handling. Alternatively, the operators can also stool, stool or small ladders carry, in order to achieve 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.

The invention also proposes a production device comprising a plurality of yarn processing machines and at least one conveying 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 device has a respective complete and only for supplying this machine guide rail set.

Alternatively, it can also be provided to run the at least two guide rail strands of the conveying device according to the invention or of several conveying devices according to the invention so that at least two guide rail strands run adjacent to each feature according to the inventive features or alternatively at least two guide rail strands correspondingly for some support positions of different machines run adjacent, but also run for at least one support slot of another machine accordingly adjacent.

With an arrangement of a larger number of machines, it is thus possible to design the conveyor device according to the invention or several conveyor devices according to the invention and to run the guide rail strands appropriately so that pairs or groups of guide rail strands provide handling areas for mounting places of different machines. As a result, the number of required guide rail strands can be kept low.

In particular, in the arrangement of a plurality of machines, in particular circular knitting machines, at least two guide rail strands can run in each case between adjacent machines in a uniform rectangular pattern and a grid-like guide rail network can be formed to form the conveyor device according to the invention by appropriate use of the web at intersections in plan view.

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.

They show:

• 1 an embodiment of the conveyor device according to the invention arranged on a schematically illustrated circular spinning-knitting machine;
• 2 an embodiment of the conveyor device according to the invention with a different course of the guide rails than in 1 ;
• 3 an embodiment of the conveyor device according to the invention with a different course of the guide rails again than in 1 and 2 ;

• 5 an embodiment of the conveyor device according to the invention with arranged along a different guide rail coils than in 4 (without representation of the machine for yarn processing).
• 6 An embodiment of the conveyor device according to the invention, in which two a spinning knitting machine almost completely circular surrounding guide rail strands are connected to each other via an external loop.

In the 1 shown conveyor device according to the invention 1 for supplying a round spinning knitting machine 40 to mounting places 42 the machine 40 to be equipped with yarn-loaded bobbins during operation and empty bobbins from the holding stations 42 to remove almost includes as a complete circle around the spinning machine 40 running guide rails 10 or guide rail strands 10 ,

Along this at least two guide rail strands 10 can be found corresponding to each mounting place 42 nearest positions 14 or handling areas 14 the guide rail strands 10 , The guide rail strands run thereby 10 so that the handling areas 14 from the respective mounting place 42 a maximum of one distance 16 which is smaller than 2 m and in the concrete embodiment also smaller than 1.5 m.

This means in particular that at each mounting place 42 the closest point of each guide rail track 10 a distance 16 of less than 2 m or 1.5 m to the mounting place 42 having.

This results for each bracket space 42 at least one stand position 18 from which an operator without walking of the feet both coils (in 1 not shown) in the handling area 14 from each guide rail track 10 as well as the coil at the mounting place 42 can reach with your hands.

Here are in 1 due to the line of sight not recognizable the stance positions 18 as podiums 18 formed as both support slots 42 and guide rail strands 10 at a corresponding height above the ground.

Schematically shown is also an operator 100 just on a correspondingly hidden pedestal 18 stands, from there to the adjacent bracket space 42 and the adjacent handling areas 14 the guide rail strands 10 access. In this case, the operator 100 due to the sufficiently small distance 16 the corresponding handling areas 14 to the appropriate bracket place 42 from the pedestal 18 out on both at the bracket place 42 located coil as well as those in the handling areas 14 Accessible in holders not shown held spools, without the standing position or the pedestal 18 to leave. In particular, in the present case, the distance 16 so small that the feet of the operator 100 for converting spools from the holders located on the guide rail strands to the mounting place 42 or conversely, do not have to be moved in steps.

Provided the two guide rail strands 10 can be approached appropriately equipped with equipped coils holder halter, the operator 100 depending on the requirement, each mounting position 42 Equip or replace existing coils, without having to carry coils with them and without bending over.

Alternative to the podiums 18 can the operator 100 also carry a suitable increase, for example, a small step ladder or the like with them and always set up accordingly at the corresponding position 18, from this increase to the respective mounting position 42 and the respective handling areas 14 access.

The guide rail strands are over a switch 22 with a transport rail 20 connected, which leads to a buffer storage for holders, not shown. Such a buffer store may have one or more corresponding turnouts similar to the turnout 22 include access to multiple, for example, parallel rails (similar to the area to the left of the switch 22 ) to position on such storage or buffer rails holders or groups or trains of holders with populated coils or emptied coils. From there or there you can as needed to or from the guide rail strands 10 or similar guide rail strands positioned adjacent to other machines 10 be added or removed.

2 and 3 show other possibilities of the course of the at least two guide rail strands 10 , Since the in 2 and 3 shown spinning machine 40 differently arranged mounting positions 42 can, the course of the two guide rail strands 10 for the formation of corresponding handling areas 14 also be different than circular, since only the distance from a bracket space 42 to the nearest points of the guide rail strands 10 low enough and consequently in areas where no mooring space 42 is provided, the distance of the guide rail strands 10 can also be bigger. However, in many machines, even circular knitting machines, also arranged along the entire circular circumference mounting slots 42 a sufficiently short distance 16 all handling areas 14 often with other than a circular course of the guide rail strands 10 be achieved.

As in 3 can also be shown several separate pairs of guide rail strands 10 or groups of guide rail strands 10 (According to the invention, more than two corresponding guide rail strands can be provided) for the supply or training of corresponding handling areas 14 from different mounting positions 42 be used.

As well in 2 as well as 3 turn are turnouts 22 indicated that connect to other transport rails not shown and optionally corresponding buffer bearings.

In 4 is again one of the 1 similar course of the guide rail strands 10 shown. Again, the two guide rail strands 10 over 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 in 4 shown, the inner guide rail strand 10 be so completely provided with holders that a more or less continuous row of coils 50 training, which also in a variety of mounting positions 42 along the circumference of the machine for yarn processing there is at least one standing position for each mounting position, from which access to corresponding coils 50 is possible.

At the same time is the outer track rail 10 empty and can while on the inner track rail 10 located coils 50 be used for the supply and supply of the machine for yarn processing, equipped accordingly with holders or driving on, bring the new coils.

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

In this case, if appropriate, the operator can be informed by means of corresponding signal light or reference indications of which guide rail strand 10 straight coils are to be removed, so that first a guide rail strand 10 is emptied or provided with emptied coils, which are to be led away again first. This then stand during the exchange of these holders on the former guide rail track 10 still the populated coils on the other guide rail line available.

5 shows that too 4 reverse situation with a similar guide rail assembly, in which just the outer guide rail strand 10 straight with coils 50 or corresponding coils 50 halternden holders is equipped or provided, while the inner guide rail strand 10 is just empty, since the corresponding holder straight along the further course of the transport rail 20 be moved from or to a buffer storage to bring away empty coils or fetch loaded coils.

A very interesting and advantageous embodiment of the invention is in 6 illustrated. In this embodiment, two are a spinning-knitting machine 40 almost completely preferred along a circle surrounding guide rail strands 10 via an external loop 60 connected with each other. Such a guide rail architecture allows the supply and removal of preferably combined to Halterungszüge holders with coils 50 to the spinning knitting machine 40 towards or away from this without reversing the direction of the trains or holders in their transport movement. In particular, such a guide rail architecture allows the realization of an endless track, in which the two rail tracks 10 are integrated. For such a configuration, the in 6 shown inlet section 62 and the in 6 shown outlet section 64 in another course, not shown, such as in a bobbin exchange storage, be connected to each other, so that in principle an operation of the conveyor with a single row of brackets for coils is possible, which rotates without reversal in the endless operation.
