Description

The invention relates to a transport device for a spinning mill for supplying ring spinning machines with feed bobbins and disposing of the empty spun tubes with a hanging rail system which is arranged between at least one roving machine and a ring spinning machine and is equipped with a storage device which enables hanging carriage trains to be temporarily stored which are either full Feed bobbins or are equipped with empty spun tubes.

Various embodiments of transport devices for roving bobbins have long been known in connection with the operation of ring spinning machines. It is known, for example, to install a network of hanging rails between roving machines and ring spinning machines, on which hanging carriage trains are movably guided, which are equipped either with fresh roving bobbins or with empty-spun tubes.

Such transport devices for roving bobbins are also described in great detail in the patent literature in numerous patent applications.

through the DE 42 13 122 A1 For example, a transport device is known in which a block of roving machines, preferably so-called roving frames, is connected to a block of ring spinning machines via a suspension rail system.

In the hanging rail system, on which hanging wagon trains circulate, which are moved either by hand, by "locomotives" or by friction wheel drives and which are equipped either with full roving bobbins or with empty bobbins, there is a cleaning device for the empty roving bobbin bobbins and a central buffer for temporarily storing hanging wagon trains switched on.

In the area of the gate of the ring spinning machines, the hanging rail system has several rows of gates, which are connected at the ends of the ring spinning machines via a switch to a ring-shaped rail track of the hanging rail system.

A comparable transport device with a hanging rail system switched on between roving machines and ring spinning machines is also in DE 195 08 399 C2 described. In this known transport device, the suspension rail system in Each area of the roving machines has a storage facility for hanging carriage trains and in the area of the ring spinning machines up to four rows of creels.

Here, too, the creel rows are connected at the ends of the ring spinning machines via points to a ring-shaped rail track of the suspension rail system.

Furthermore, so-called transfer devices are known in connection with transport devices for roving bobbins. Such transfer devices are intended to reduce the cost of switches that are required in the hanging rail systems.

In the DE 10 2007 014 596 A1 and the DE 10 2007 029 288 A1 are described, for example, transport devices for roving bobbins, which, as usual, are arranged between at least one roving frame and a plurality of ring spinning machines and have a network of hanging rails on which hanging carriage trains are movably guided.

These known transport devices have at least one main overhead rail and several branch overhead rails, with a transfer device being arranged between the main overhead rail and the branch overhead rails.

This means that a transfer device is installed in an area between a main overhead rail and one of the branch overhead rails, which can be moved along the main overhead rail and has two slidably mounted carriages with overhead rail sections.

The carriages can be moved in the transfer device transversely to their direction of travel in such a way that their suspension rail sections can be aligned with the main suspension rail and with one of several branch suspension rails.

Suspension wagon trains can then be transferred in both directions via this suspension rail connection. This means that such transfer devices can be used to move trains of hanging carriages loaded with full roving bobbins from a main hanging rail track into a branch hanging rail track in the creel of a ring spinning machine, and after the roving bobbins have been worked off again from the branch hanging rail tracks to the main Overhead rail are returned, which is connected to a roving machine or a buffer.

The disadvantage of the known transport devices described above, however, is that hanging carriage trains that are positioned in the creel rows of a ring spinning machine can only be exchanged individually and therefore one after the other.

This means that if several hanging carriage trains are positioned in the area of the creel rows of a ring spinning machine, all of which are to be exchanged, the changing process is relatively time-consuming, since before a hanging carriage train that is equipped with new, full roving bobbins enters one of the creel rows of the creel Ring spinning machine can retract, always first a hanging carriage train, which has empty spun sleeves, must be moved out of the gate row.

In modern ring spinning machines, which have a large number of creel rows, for example four to ten creel rows, the changing process is correspondingly relatively lengthy and leads to not inconsiderable production losses.

In the case of lot changes in particular, where all the hanging carriage trains positioned in the rows of creels have to be changed, there have usually been considerable production losses since the ring spinning machine is switched off during the entire changing process.

Proceeding from the prior art described above, the invention is based on the object of providing a transport device for a spinning mill, which is used to supply ring spinning machines with feed bobbins and to dispose of empty spun tubes and which has a hanging rail system with a storage device arranged between at least one roving machine and a ring spinning machine , with which hanging wagon trains can be exchanged extremely quickly and therefore very effectively, especially when batches are changed.

This object is achieved according to the invention in that a creel with a large number of creel rows is installed in the area of the ring spinning machine, which are connected to the hanging rail system via a switch configuration in such a way that, if necessary, a plurality of hanging carriage trains, which have empty spun tubes, can be pulled out of the creel rows at the same time the ring spinning machine can be extended and that the same number of hanging carriage trains, which are equipped with full supply bobbins, can then be moved back into the creel rows of the ring spinning machine at the same time.

According to the invention, it is provided that the switch configuration has a number of straight connecting tracks and a number of crossing tracks crossing the connecting tracks, and that a pre-switch is installed to connect the connecting tracks with the crossing tracks, and a bridge switch is installed in the crossing areas of connecting tracks and crossing tracks.

The number of connecting tracks and the number of crossing tracks are the same and correspond to the number of creel rows installed in the creel of the ring spinning machine.

Advantageous embodiments of the invention are the subject matter of the dependent claims.

The transport device according to the invention has the particular advantage that the simultaneous extension of a plurality of hanging trolley trains that are equipped with empty spun tubes and the subsequent simultaneous retraction of the same number of hanging trolley trains that have fresh supply bobbins, the time that was previously required by several replacing hanging carriage trains positioned in the creel rows of a ring spinning machine is significantly reduced.

Since the period of time during which the ring spinning machine is switched off is thus also shortened, the productivity of the ring spinning machines is consequently also significantly improved with the transport device according to the invention, in particular when lot changes are often pending.

In an advantageous embodiment, it is provided that the storage device is designed in such a way that all hanging carriage trains discharged from the creel rows of the ring spinning machine can enter the storage device at the same time and then the same number of hanging carriage trains can move out of the storage device again at the same time in the direction of the ring spinning machine.

This means that when hanging carriage trains are exchanged, delays of any kind are avoided, even though a large number of hanging carriage trains are exchanged at the same time, both in the area of the ring spinning machines and in the area of the storage device.

Preferably between four and ten creel rows are arranged in the area of the creel of a ring spinning machine, an arrangement with six creel rows having proved to be particularly advantageous in modern ring spinning machines.

The arrangement of six creel rows, i.e. three creel rows per longitudinal side of the spinning machine, not only ensures that the numerous spinning positions of the ring spinning machine are properly supplied with roving in a simple manner, but also ensures that, if necessary, hanging carriage trains that have empty spun tubes, can be exchanged for hanging trolleys that are equipped with fresh roving bobbins.

The storage device preferably has a pre-storage arrangement which has a plurality of first rails corresponding to the number of creel rows of the at least one ring spinning machine and the same number of second rails. In each case, a first track is preferably arranged adjacent to a second track and a first switch is arranged and configured at the end of the first and second tracks facing the at least one ring spinning machine in such a way that when the first switch is in a first position, a suspension wagon train can enter the first track can enter and in a second position of the first switch a hanging wagon train can exit the second track. Thus, immediately after the entry of hanging wagon trains with empty spun tubes into the first tracks, hanging wagon trains temporarily stored in the second tracks can be extended with full roving bobbins in the direction of the ring spinning machines. A batch change on a ring spinning machine can thus be carried out quickly.

A second switch is preferably arranged and designed at the other end of the first and second tracks in such a way that in a first position of the second switch a hanging wagon train can exit the first track and in a second position of the second switch a hanging wagon train can move into the second track can drive in. In this way, the second tracks can advantageously be filled again with hanging car trains with full roving bobbins and the hanging car trains with empty spun bobbins can be moved out of the first tracks. The hanging carriage trains with the empty spun tubes can be driven to the roving machine or a main store.

However, it is special if the storage device between the pre-storage arrangement and the at least one roving machine comprises a further pre-storage arrangement which has the same number of rails as the at least one ring spinning machine has creel rows. In this way, two lot changes can be carried out immediately one after the other.

According to a development of the invention, the connecting tracks lead to the storage device and the crossing tracks lead to the creel rows of the ring spinning machine.

The pre-switches preferably each have a branch position and a straight-ahead position. In the branching position, the crossing tracks are preferably connected to the connecting tracks, and in the straight position, the connecting tracks are preferably connected to the connecting tracks of a further switch configuration.

The bridge points can preferably be arranged in such a way that either the connecting tracks or the crossing tracks are continuous. For this purpose, the bridge points can have a rotatable track element, for example.

Furthermore, the pre-switches are each equipped with their own drive, for example with an electric motor drive, while the numerous bridge switches are connected by a lever linkage and can be actuated by means of a common drive, preferably also an electric motor drive.

Since both the drives of the pre-switches and the drives of the bridge switches are connected to a central control unit in the spinning mill, a defined control of the switch configuration is guaranteed at all times if required.

This means that switch configurations designed in this way enable a large number of hanging carriage trains to be guided in a relatively simple manner at the same time, so that, if required, both a large number of hanging carriage trains can be simultaneously and safely discharged from the creel rows of a ring spinning machine, and then the same number of hanging carriage trains can be fed back in at the same time the creel rows of a ring spinning machine can be introduced.

The invention is explained in more detail below with reference to exemplary embodiments illustrated in the drawings.

the 1 shows a side view of the creel of a ring spinning machine 1. However, the ring spinning machine 1 arranged in a spinning mill is shown only very schematically, i.e. this ring spinning machine 1 is shown in 1 shown.

As can be seen, the gate 2 of the ring spinning machine 1 in the exemplary embodiment has three rows of gates 3 per longitudinal side of the spinning machine, i.e. a total of six rows of gates 3 formed by rails 9 of a suspension rail system identified overall by the reference numeral 10 .

Hanging wagon trains 11 run in these rails 9 of the hanging rail system 10, which either, as in 1 indicated, are equipped with full roving bobbins 12, preferably flyer bobbins, or have empty-spun sleeves.

The hanging wagon trains 11 can be moved in the hanging rail system 10 and, as is known per se, usually consist of support members that are flexibly connected to one another, so that they can also travel through curves.

The support members are guided in a manner known per se by means of rollers in the downwardly open, Ω-like rails 9 of the suspension rail system 10 .

Such hanging wagon trains 11 are usually driven either by hand, by "locomotives" or by friction roller drives.

the 2 shows a plan view of a transport device arranged in a spinning mill and designed according to the invention for supplying ring spinning machines 1 with roving bobbins 12 or for disposing of the empty bobbins spun by the ring spinning machines 1 in the course of the spinning process.

As already explained above, the transport device has a hanging rail system 10 on which hanging wagon trains 11 are movably guided.

As can also be seen, in the exemplary embodiment, a ring spinning machine block consisting of three ring spinning machines 1 is connected to two roving machines 14 via a suspension rail system 10 .

In the area of the gates 2 of the three ring spinning machines 1, a total of six rows of gates 3 are installed, each of which is connected to the suspension rail system 10 via a switch configuration 15.

As in 2 further indicated, the hanging rail system 10 is also equipped with a storage device 16 . The memory device 16 has a first Pre-storage arrangement, at the ends of which the switches 22 and 23 are arranged. In addition, storage device 16 includes a second pre-storage arrangement 17.

The storage device 16 is also connected via a siding 4 to at least one roving machine 14, with two roving machines 14 being shown in the exemplary embodiment.

In the roving machine 14, the suspension carriage trains 11 are fitted with fresh roving bobbins 12. This means that incoming hanging wagon trains 11 equipped with empty spun tubes are converted as soon as possible on the roving machine 14, i.e. equipped with fresh roving bobbins 12 and then transported via the siding 4 to the storage device 16, where they are initially temporarily stored in the second pre-storage arrangement 17 , which is connected to the first pre-storage arrangement of the storage device 16 in terms of conveying technology.

the 3 shows on a larger scale a section of the 2 Hanging rail system 10 shown in its entirety.

As can be seen, the gates 2 of the ring spinning machines 1 each have a total of six rows of gates 3, each of which has a switch configuration 15, which is described below with reference to FIG figures 4 and 5 is explained in more detail, are connected to the suspension rail system 10 of the transport device designed according to the invention.

The switch configuration 15 and thus the gate rows 3 are coupled to a storage device 16 which has pre-storage arrangements.

The first pre-storage device has adjacent tracks 18 and 19 in each case. This means that the two tracks 18 and 19 are right next to each other. The number of track pairs 18 and 19 corresponds to the number of creel rows 3 of a ring spinning machine 1. In the present exemplary embodiment, the first pre-storage device therefore has six track pairs 18 and 19 and thus a total of twelve tracks.

The storage device also has a second pre-storage device 17. The pre-storage device 17 has the same number of rails 20 as a ring spinning machine has creel rows. In the present embodiment, there are six tracks 20.

the figures 4 and 5 each show different views of an advantageous embodiment of a switch configuration 15.

the 4 shows the switch configuration 15 in plan view, while the Fig.5 represents a bottom view.

Like in particular figure 5 As can be seen, such a switch configuration 15 in the exemplary embodiment has six so-called connecting tracks 21, which run through the switch configuration 15 in a straight line, and six so-called crossing tracks 25, which cross the connecting tracks 21 and which each form an extension of one of the creel rows 3 of a ring spinning machine 1.

In the conveying direction F, pre-switches 5 are installed on the input side of the switch configurations 15 , each of the total of six pre-switches 5 being arranged in the region of an incoming connecting track 21 and each being controllable in a defined manner by a separate drive 24 .

Furthermore, such switch configurations 15 are each equipped with bridge switches 6 in the crossing areas of connecting tracks 21/crossing tracks 25.

In the present exemplary embodiment, the switch configurations 15 each have a total of fifteen bridge switches 6 .

As shown, if required, depending on the switching position of the pre-switches 5 and the bridge switches 6, up to six hanging carriage trains 11 can be simultaneously discharged from the creel rows 3 of a ring spinning machine 1 and then up to six hanging carriage trains 11 can be moved back into the creel rows 3 at the same time.

However, hanging wagon trains 11 coming from the storage facility 16 can enter the switch configuration 15 via the connecting tracks 21, through a corresponding switch position of the pre-switches 5 or straight through the switch configuration 15 in the direction of the outgoing connecting tracks 21 and thus to a subsequent switch configuration 15 to be forwarded.

How out 4 As can be seen, the pre-switches 5 each have a separate electric motor drive 24, the drives 24, like the drive 8 for the bridge switches, preferably being controllable in a defined manner via a central control device of the spinning mill.

The numerous bridge switches 6 are also connected via a lever linkage 7 and are also connected to their common drive 8 via this lever linkage 7 .

The arrangement and design of a switch configuration 15 shown in the exemplary embodiment has the particular advantage that, if necessary, up to six hanging carriage trains 11 can be ejected simultaneously from the creel rows 3 of a ring spinning machine 1 without any problems, and then the same number of hanging carriage trains 11 can be simultaneously fed back into the creel rows of the ring spinning machine without any problems 1 can be fed in, which leads to a significant reduction in machine downtime, especially when changing batches.

Function of the transport device according to the invention:

When the roving bobbins 12 of the hanging carriage trains 11 positioned in the creel rows 3 of the creel 2 of the ring spinning machine 1 are unwound on one of the ring spinning machines 1, for example on the middle ring spinning machine, a change of the hanging carriage trains 11 is necessary in order to be able to continue the spinning process, whereby the changing process should take as little time as possible.

This means that the six hanging carriage trains 11 positioned in the creel rows 3 of the middle ring spinning machine 1 and now having empty spun sleeves must be exchanged as quickly as possible for six hanging carriage trains 11 that are equipped with fresh roving bobbins 12 .

In order to be able to simultaneously eject the six hanging carriage trains 11 equipped with empty spun tubes from the creel rows 3 of the ring spinning machine 1, the switch configuration 15 arranged on the input side of the creel 2 of the middle ring spinning machine 1 is first switched properly.

This means that the pre-switches 5 and the bridge switches 6 of the relevant switch configuration 15 are switched in such a way that each of the rows of gates 3 is conveyed is continuously connected to one of the connecting tracks 21 of the suspension rail system 10, which run through the switch configuration 15 in a straight line.

For this purpose, the pre-switches 5 are switched to their branching position by their drives 24 and the bridge switches 6 are controlled in such a way that they are available for passage with respect to the crossing tracks 25 in terms of conveyance.

This means that the bridge switches 6, which are connected to a common drive 8 via a lever linkage 7, are switched, for example by the central control device of the spinning mill, in such a way that all hanging wagon trains 11 cross the connecting tracks 21 in between and finally via the associated pre-switch 5 into the connected connecting track 21 can enter.

All hanging wagon trains 11 then continue to run in the direction of the storage device 16 via the connected connecting tracks 21, with the connecting tracks 21 each being connected to the points 22 of the first pre-storage device, as can be seen.

The first pre-storage arrangement, which has a total of 12 tracks 18, 19, is equipped with points 22 and 23 in its end regions.

In practice, a hanging wagon train 11 loaded with fresh roving bobbins 12 is temporarily stored on the tracks 19 of the first pre-storage arrangement.

This means that the incoming hanging wagon trains 11 loaded with empty spun tubes are controlled by the switches 22 in such a way that they run onto the empty tracks 18 of the first pre-storage arrangement, where they are temporarily stored.

The six hanging wagon trains 11 loaded with fresh roving bobbins then leave the first pre-storage arrangement and reach the switch configuration 15 via the connecting tracks 21, which still shows the switching position that was set to discharge the hanging wagon trains 11 loaded with empty spun bobbins.

This means that the six hanging carriage trains 11 loaded with fresh roving bobbins are deflected in the direction of the creel rows 3 and can enter the creel rows 3 of the ring spinning machine 1 at the same time.

After the suspension carriage trains 11 have been correctly positioned, the piecing process can be started again immediately on the ring spinning machine 1 .

Subsequently, from the second pre-storage arrangement 17, trains of hanging carriages 11, which have been loaded with fresh roving bobbins 12 on the roving machine 14, are transferred to the first pre-storage arrangement. For this purpose, the switches 23 are set in such a way that the hanging wagon trains 11 with fresh roving bobbins move from the tracks 20 into the free tracks 19 of the first pre-storage device. In addition, the hanging car trains 11, which were previously temporarily stored on the tracks 18 of the first pre-storage arrangements and are equipped with empty spun tubes, are transferred to the tracks 20 of the second pre-storage arrangement 17 by appropriate adjustment of the points 23, from where the hanging car trains 11 later, i.e. as soon as this is possible , are sent via the connecting track 4 to the roving machine 14.

On the roving machine 14, the suspension carriage trains 11 are then again fitted with fresh roving bobbins 12.
