Description

The invention relates to a method for operating a Automatic winder according to the preamble of claim 1 or a cross-winding machine according to the preamble of claim 2.

Spooling machines with a variety of similar winding units as well as a transport system for the supply and disposal of the Winding units with spinning cops or empty tubes are in various embodiments known.

There are, for example, cross-winding machines known whose Transport systems have machine-end interfaces, fed via the spinning system in the transport system or unwound empty tubes can be disposed of. The spinning cops are thereby aufm in the Production process upstream textile machines, preferably Ring spinning machines, manufactured and, for example by means of large-volume transport container to the cheese winder transported by so-called flat-round conveyors isolated and Kopsaufsteckeinrichtungen on the Transport plate of the transport systems of these cheese winder be handed over.

In another known embodiment that is Transport system of the cheese, preferably via a so-called converter, with the transport device of the Spinnkopse producing textile machine connected.

That is, the ring spinning machine and the winder have special transport systems, each with machine-specific transport plates for the spinning cops or the empty tubes.
The spinning cops and the empty tubes are thereby transferred by means of a preferably continuously operating converter, as described for example in DE 196 46 337 A1, from one transport system to the other transport system.

Such a transport system is known from EP-A-0 402 630 and provides the closest prior art.

In order to avoid machine downtimes, the capacities of the composite textile machines operating at different speeds are coordinated.
It should be ensured in any case, that in their work process much slower ring spinning machine, which has a disproportionately large number of jobs, does not have to wait for the winder.

Taking into account the produced in a spinning mill, different yarn counts, this often leads in practice in addition, the capacity of the dishwasher chosen slightly larger is considered the capacity of the connected ring spinning machine with the result that the winder the delivered Spinning cops usually have already rewound before the Ring spinning machine is again dope and thus new spinning cops be available.

So far, in such a case, there was only the possibility of either having the winder run through until the arrival of new spinning cops or simply switching off the winder.
To let go through the winder, this not only means unnecessary energy consumption, but can also lead to difficulties in the field of transport system of the cheese winder, as it usually comes on the transport paths of the winder to a jam leerhülsenbestückter transport plate.
Such a jam of transport plates, in particular on the sleeve return path, often leads to jamming in the area of the mouths of the leading to the winding units transverse transport links, which are usually only to be eliminated by a manual intervention of the operator.

Also the temporary uncontrolled shutdown of the Spinning machines in the absence of Spinnkopszufuhr can to Difficulties and some not insignificant Disadvantages.

In the event of an uncontrolled shutdown of the automatic winder For example, at all winding stations, you immediately get one Thread cut. But every thread cut is one Quality reduction of the cheese to be produced, Such vicious thread cuts should be avoided as much as possible become.

In addition, it comes with an uncontrolled shutdown of the automatic winder inside the transport system to a completely vicious distribution of spinning copter and empty case tipped transport plates.
This completely uncontrolled distribution of the transport plate leads when reinserting the Spinnkopszufuhr when usually at the same time from each winding unit a transport plate is discharged to the sleeve return path, in the area of the mouths of the transverse transport routes again and again to congestion.

There is also the risk that it comes when resuming the Spinnkopszufuhr to difficulties, since in the area of the converter is often not immediately sufficient empty-tube-equipped transport plate available, which can be replaced at the converter with new spinning cops.
As a result, the clearing of the Cowemat routes can be delayed, which means that the ring spinning machine after completion of their new spinning cops Doffvorgang can not start immediately because one of their Cowemat routes is not completely cleared.
Since every standstill of the ring spinning machine not least due to their large number of workstations (up to 1200 and more spinning spindles) immediately means a significant loss of production, even the uncontrolled shutdown of a cheese winder is not entirely risk-free or requires even greater overcapacity of the automatic winder over the ring spinning machine.

Based on the aforementioned prior art is the Invention the object of the invention to provide a method that the operation of arranged in conjunction with spinning machines Reelers improved.

This object is achieved according to the invention by a method as described in claim 1.

Advantageous embodiments of a cheese winder for Performing the method according to the invention are the subject of the subclaims 2 to 9.

The inventive method has in particular the Advantage that the cross-winding machine in the absence of Spinnkopszufuhr immediately and controlled in one energy-saving mode is shut down, wherein Nevertheless, it is ensured that the to be produced Cheeses maintain their quality standard and that Reel-fed automatic rewinding machine when replacing the spinning-cop supply Immediately switch back to trouble-free normal operation can.

This means that the cross-winding machine is switched on the one hand as early as possible to a more cost-effective mode, on the other hand, it is nevertheless ensured that in the transport system of the cheese winder always sufficiently empty-tube-equipped transport plates are available.
If required, that is, when the spinning-cop supply starts again, the empty tubes kept available can immediately be exchanged by the converter for spinning cops, and thus, if required, the clearing-off process of the ring spinning machine can be started at any time.

The sensory monitoring of the spinning cop supply described in claim 2 allows an early reaction to the given situation.
That is, a arranged in the transport system of the automatic winder sleeve monitor ensures at the receipt of the signal "no Spinnkopszufuhr" immediately that initially the on the sleeve return path, equipped with empty tubes transport plate no longer in the direction of the converter, but via the so-called passage directly to Kopszuführstrecke the cross-winding machine redirected and then held in the area of the sleeve return path or the distribution route.

As set forth in claim 3, the sleeve guard is included preferably designed so that, as soon as a predetermined Number of empty hulled transport plates directly to Kopszuführstrecke has been diverted by the controller the sleeve guard a corresponding signal to the Central control unit of the cheese winder is discontinued. The The central control unit then automatically manages the for a Energy saving operation necessary steps in a given Sequence.

The number of redirected transport plates corresponds to this advantageously about the number of winding units of the relevant automatic winder (claim 4). Such Number is usually sufficient to ensure that when re-inserting the Spinnkopszufuhr the converter at least so many empty tube-equipped transport plates are available that the time required for the winding units to turn Spinning spins and thus for the exchange process on Provide converter can be bridged.

The described in claim 5, advantageous embodiment makes sure that if there is no Spinnkopszufuhr the Cross-winding machine then also on energy-saving operation shut down if, for example, due to Faults at the winding units, the predetermined number to be ejected, empty sleeve equipped transport plate a predetermined period has not yet been reached.

The central control unit sets after the input of a Corresponding signal of sleeve monitor control immediately Series of control commands (claims 6 and 7) lead that the cheese from the normal operation in one shut down defined energy-saving mode. This energy saving operation ensures that the in Transport system of the automatic winder located Transport plates are positioned so that after Doffen the Ring spinning machine and thus when reinserting the Spinnkopszufuhr immediately sufficient empty tube equipped Transport plate available and thus the cross-winding machine Raised again without difficulty to normal operation can be.

Further details of the invention are given below Embodiment illustrated with the drawings removable.

Fig. 2

a plan view of the schematically illustrated transport system of the cheese according to the invention.

In Figure 1 is a perspective view of a Textile machine composite shown, consisting of a Ring spinning machine 30 and a Kreuzspulaütomaten 25 consists. As indicated, the ring spinning machine 30 has a Transport device 31, the transport routes 33a respectively 32b with a continuously working one Converter 34 is connected. The converter 34 is included in turn via transport links 33b and 32a the transport system 21 of the automatic winder 25 is connected. The transport sections 32 and 33 can thereby additionally via one, not in the present embodiment be shown cop bridge led. In such a case is between the two. Textile machines a passage for the Operating personnel given.

The relatively schematically illustrated transport device 31 of the ring spinning machine 30 consists essentially of a guided around the spinning stations, usually upright standing, defined controllable drive belt 35, the corresponding approaches for conveying the spinning machine's own (not shown) transport plate has, and so-called Cowemat routes 36th , 37. The cowemat stretchers 36, 37 extend on both sides of the ring spinning machine and are connected at the machine end via a cowemat connection 38. In the area of the cowemat routes 36, 37, sensor devices (not shown) are generally also installed which detect the respective degree of filling of these sections and are preferably connected to the control device 49 of the ring spinning machine 30.
The control device 49 stands in this case, for example via a data bus 50 with the central control unit 27 of the automatic package winder 25 in connection.

The Cowemat routes 36, 37 are on the Cowemat route 38 opposite side, as above already mentioned, via transport lines 33a and 32b connected to a converter 34.

As is known, by means of the converter 34 on arranged the spinning machine own transport plates Spinning head 39 on spulmaschinentenische transport plate 41st transhipped. At the same time, the converter 34 takes the empty tubes 40 from the bobbin-specific transport plates 41 and put them on in the conveyor 31 circumferential, Spinning machine own transport plates back.

The spinning coploaded transport plates 41 are then via the transport route 33b to the transport system 21 of the Reelers 25 forwarded while the spinning machine own transport plate with the empty tubes 40 over the transport path 32b to the transport device 31 of Ring spinning machine 30 run back.

In Figure 1, in perspective view, the various Transport routes of the winding machine own transport system 21 in each presented while the presentation of the Reelers 25 essentially on the Spinnmaschinenendseitig arranged energy and Control unit 22, as well as position information for the winding units A, B, etc. limited.

The transport system 21, which is used for supplying and disposing of the spinning stations A, B ... etc. with spinning heads 39 and empty tubes 40, for example, installed on a chassis 20 which is disposed below the winding units of the automatic cheese winder.
The transport system 21 known per se has a machine-length Kopszuführstrecke 2 adjacent to the transport section 33b. One or more preparation sections 3 branch off from the Kopszuführstrecke 2, on each of which a so-called Kopsvorbereitungsstation 42 is positioned. In the Kopsvorbereitungsstationen 42, as is known, the back turns of the cops dissolved and placed tip windings on the tube tips.
One of the preparation stations can also be designed as a so-called residue preparation station for already partially unwound spinning cops.

The end of the preparation routes 3 are each a Abtransportstrecke 4 with a memory line 5 and through corresponding arrangement of guide elements, which, as in 2 indicated, form a removal path 4a, again with the Kopszuführstrecke 2 connected.

From the memory line 5, which alternately from left to Clockwise is switched off, cross transport 6 go from.

The transverse transport routes 6, to the individual Spinning points A, B ... lead etc., in turn are at the end the sleeve return path 8 connected to which a Distributor route 9 connects.

In der.Verlängerung the distribution route 9, the transport path 32a is arranged, which leads to the converter 34.
The distribution route 9 is also connected directly to the Kopszuführstrecke 2 via a passage 1.
The transport system 21 further has a branching from the passage 1, so-called sleeve cleaning section 10, in the area, for example, a sleeve cleaning 13 is arranged on a transverse passage 11 and a manual preparation path 12. The hand preparation route 12 is via the transverse passage 11 with both Kopszuführstrecke 2 and connected to the distribution route 9.

In the area of the distribution route 9, a sleeve monitor 24 is arranged, the control device 46 of which is connected via the bus system 50 to the central control unit 27 of the automatic package winder 25 and to a sensor device 45 arranged in the region of the transport path 33.
At the entrance of the distribution route 9 also a sensor device 51 is arranged, which detects the degree of filling of the sleeve return path 8.

The transport system 21 of the automatic winder 25, the in Fig.2 schematically shown in plan view and for example in the DE 196 36 661 A1 is described in detail, has Altogether over an extensive Aktorik and sensors, the a defined transport of the transport plate 41 within the transport system 21 of the automatic winder 25 allows.

The transport plate 41 each have one defines magnetizable encoder that allows the respective loading state of the transport plate, for Example, with a spinning-cup carrier or empty sleeve-fitted, identifiable close.

As can be seen from FIG. 2, in the region of the transport system 21, for example, a multiplicity of electromagnetic deflectors 14 are positioned which can be energized selectively and which, in the activated state, allow the transport plate 41 surrounded by a ferromagnetic ring to be redirected into an adjacent transport path.
Furthermore, the transport system 21 has numerous sensor devices 16, preferably Hall sensors, which respond to defined in the transport plates 41, magnetizable encoders.
The magnetic coding of the arranged in the transport plates 41 information carrier can be changed via Codierspulen 17.
Sensor devices are also arranged in the area of Kopsvorbereitungsstationen 42. These sensor devices 15 monitor the success of the preparation devices 42.
Within the transport system 21 also some stoppers are provided which allow jamming of transport plates 41 on the particular transport routes.

Function of the device:

When the ring spinning machine 30 completes its spool travel, the means the spinning cops has finished, are by means of two lateral, machine-length (not shown) Doffbalken at the same time all finished spinning cops from the spindles of the Removed ring spinning machine and on spinning machine own Transfer plate transferred in front of the spinning stations on the Cowemat routes 36, 37 are available. Subsequently, the Drive belt 35 further clocked by a spindle division and while the empty sleeve tipped Transporteller so before the Spinning the ring spinning machine 30 positions that the Empty sleeves for the arranged on the Doffbalken Gripping devices are manageable.

If the ring spinning machine 30 again equipped with empty tubes and thus clearing away, which is detected by means of a corresponding (not shown) device and reported, for example via the machine bus 50 to the central control unit 27 of the cheese winding 25, by means of the conveyor belt 35, the transport plates with the spinning noses 39 transported in the transport direction F and reach via the transport path 33 a to the converter 34. The converter 34 loads the spinning cops 39 from the spinning machine's own transport plates on bins specific transport plate 41 to. At the same time, the converter picks up on the transport plates 41 brought up empty tubes 40 and sets them on the spinning machine's own transport plate.
The now loaded with spinning noses 39 transport plates 41 are transferred to the transport system 21 of the automatic winder 25, while the now loaded with empty tubes 40 spinning machine own transport plate to the transport device 31 of the ring spinning machine 30 are returned.

The spinning cop supply on the transport path 33 is permanently monitored by a sensor device 45, which is preferably also connected via the machine bus 50 to the control device 46 of the sleeve monitor 24.
As soon as the sensor device 45 ascertains that no spinning-cop feeding takes place via the transport path 33a and a device (not shown) arranged in the area of the ring spinning machine 30 reports that the transport device 31 of the ring spinning machine 30 has been cleared properly, a corresponding signal is sent to the control device 46 the sleeve guard 24 discontinued, which in turn ensures that the incoming on the distributor route 9, equipped with empty tubes 40 transport plate 41 are no longer sent over the transport path 32a to the converter 34, but are passed through the passage 1 to Kopszuführstrecke 2.
That is, the arranged at the junction to the passage 1 electrical switch 14a (see Figure 2) is activated and then deflects the ferromagnetic transport plate 41 in the direction of the passage 1 from. By way of a sensor device 16a arranged in the region of the sleeve monitor 24, the number of empty tubes 40 removed is also detected. The sensor device 16a, which is preferably designed as a Hall sensor, recognizes on the basis of the coding of the transport plate whether the transport plate has already been counted.

The discharged, empty sleeve equipped transport plates 41 arrive via the Kopszuführstrecke 2, the link 7 and the sleeve return path 8 again to the distribution route 9, where they are eventually stowed on the sleeve guard 24.

When a predetermined number empty-carrying carrier plate 41 is discharged, sets the control device 46 of the sleeve monitor 24 via the machine bus 50, a signal i to the central control unit 27 of the automatic winder 25 from.
The central control unit 27 then ensures that the cross-winding machine 25 is shut down in a controlled energy-saving mode.

That is, the central control unit 27 of the automatic winder 25 ensures that first the drive 19 of the storage section 5 and the drives 18 of the transverse transport sections 6 are turned off. Furthermore, the (not shown) drive the suction system of the winder is turned off and set the winding units in shift lock.
That is, in Spulposition located spinning cops are wound to the end, a cop change is not started. In addition, the preparation stations 42 are switched off and a signal lamp 26 is switched to flashing or continuous light.

After a predetermined period of time, the Central control unit 27 finally that even the Kops feed line 2 drive 28, drive 29 the Link 7, the drive 47 of the Sleeve return path 8 and the drive 48 of Distributor route 9 is turned off. The cheese winding machine 25 is thus in a power-saving standby mode the so-called energy-saving operation.

The cross-winding machine 25 remains in this energy-saving mode, until the central control unit 27, for example via the Control device 49 of the ring spinning machine 30, above informing that the ring spinning machine 30 again clearing is ready and until the signaling device 45 reports "Spinnkopszufuhr".

Upon receipt of appropriate signals provides the Central control unit 27 of the cheese winder 25 then automatically ensure that the above drives of the Transport system 21 are switched on again.

That is, the converter 34 can immediately with the acquisition the spinning cops 39 delivered by the ring spinning machine start, because at the converter immediately enough empty tubes 40 standing by the sleeve keeper 24 dammed up.

When the sensor device 51 at the entrance of the distribution route 9 registered that the sleeve return path 8 is cleared, the shift lock of the winding units is canceled. Subsequently will be up to that time in the winding positions of Spool on the transverse transport 6 standing Transport plate to the sleeve return path 8 discharged out and without complications via the sleeve return path 8 conveyed away.

The above-described type of communicative connection between the sensor device 45 and the sleeve monitor 24 or its control device 46 and the sleeve monitor 24 with the central control unit 27 of the automatic package winder 25 represents only one possible embodiment.
There are certainly other variants of a functional linkage of this device conceivable, without departing from the general inventive concept.
