A vertical rail 21 guided between side guide rollers 20 is fixed to this vertically movable rail section 14, 2, and a lifting device 17 acts on the vertical rail 21.

After the transfer of a new group of bobbins to the suspension conveyor arrangement, the movable carriage 15 remains at a height slightly below the suspension conveyor arrangement.

This object then advances by one graduation, so that the subsequent bobbin adapter 5, in which the empty sleeve is inserted, is inserted into this bobbin holder with the empty sleeve after the lowering of the movable carriage 15 or the rail section 14.2. In order to move the
By running up the movable platform 15, it can be removed and the new working cycle described for working positions ① to ② can therefore be carried out.

In FIG. 3, the bobbin adapter 5 partially supports the bobbin sleeve 6 with the remaining yarn wound in the working positions ① and ②, but the bobbin adapter 5 is empty in the working position ②, Therefore, the state is shown in which a full bobbin 9 is ready to be received. The rail section 14.l is shown swinging out from the guide rail 14 at this point.

As a result of the advance of the rail section 14.1 in the direction of force, arrow f, the bobbin adapter 5 with the loaded empty sleeve 6 and the ejection auxiliary piece 7 is moved into the area of the sleeve removal device 22 in the working position (2). This device 22 comprises horizontally adjustable clamping jaws 23 and between the jaws a bobbin adapter 5 with an empty sleeve 6 is inserted into the lower sleeve 6 with joint advancement of the two clamping jaws 23.

With the advance of the rail part 14.1, in the working position 1, the empty bobbin adapter 5 simultaneously advances into the sleeves of the two thread bobbins 9, that is to say also into the discharge auxiliary piece 7 which has a central hole. After the two bobbins 9 have been received by the bobbin adapter 5 in the area of the working position ■, the lifting table 1
8 is lowered to receive a new bobbin group consisting of two bobbins 9 from the conveyor belt 2.1.

After the return of the rail part 14.1 and the pivoting back into the guide rail 14, a closed drive circuit is established again and the transport member 12 therefore moves the individual carriage 15 into the respective next working position. In order to do this, one further step is taken.

After the two empty sleeves have been removed from the bobbin adapter in the area of working position ■, the upper sleeve 6, which is at the front in FIG. The lower sleeve 6 falls into the same magazine after the gripping jaws 23 are opened. The sleeve 6, which is in the magazine 26 and is probably still partially wound, is continuously taken up by a lifting table 28, which grips the sleeve from the inside and runs up to an elongating mandrel which grips the sleeve firmly by extension. , and transferred. Thereafter, the diagrammatically shown cutting device 29 is activated, which device comprises a rotating separating knife. By running the tearing knife along the generatrix of the sleeve 6, which is held firmly by the elongating mandrel, the yarn layer still present on the sleeve is cut and is sucked out and carried away by the suction device.

After the cutting device 29 has returned to its initial position again, the sleeve 6 is released on the elongated mandrel.

During the lowering of the lifting table 28 for the purpose of receiving the next sleeve from the sleeve magazine 26, the emptied sleeve 6' is moved laterally from the lifting table to the conveyor belt 2 by opening the side flaps 31. 2 and the empty sleeves 6' are then again fed to the individual winding stations of the winding machine of FIG.

Parallel in time to the cleaning of the sleeve (residual thread removal), the fully wound thread bobbin 9 is carried onto the lifting table 1 day and, after the lifting of the lifting table 18, on the subsequent empty bobbin adapter 15. The bobbin is brought to the position where it is received again. After the two thread bobbins 9 have been placed on the lifting table 18, a new ejection auxiliary piece 7 is inserted between the two thread bobbins 9 as described above.

FIG. 4 shows an adjustment system 16 for swinging the rail section 14.1 out of the conveying path formed by the guide rail 14 and for horizontally displacing this guide section in the direction of the arrow f. . This adjustment system consists of a carriage in the form of two horizontal rails 33 (only one of which is shown in FIG. 4) that can be rotated between guide rollers 32 and a cross crossbar 34 fixed between these horizontal rails 33. It has become. A swingably mounted lifting cylinder 35 acts on the rear end of this crossbar 34. Furthermore, a rank drive 36 is installed on the crossing crosspiece 34 for the connecting rod 37. This connecting rod 37 acts at its front end on one lever arm of a lever system 39 which is pivotable about a horizontal axis 38, and on the second lever arm of said system 39 the rail part 14.1 is placed. ing.

By actuating the crank drive 36, the rail section 14.1 is swung out of the conveying path formed by the guide rail 14 about a horizontal axis 38. By actuating the lifting cylinder 35, this rail section 14.
1 is projected horizontally in the direction of the arrow f8 in order to make it possible to carry out the working steps in the working positions ■ and ■.

The adjustment mechanism is again schematically illustrated in FIG.

A particular feature of the operating method according to the invention and the device according to the invention is, more particularly, that the individual work steps are arranged over four work positions or work cycles.

The performance of the transfer device is therefore considerably increased in that one bobbin preparation station can feed several bobbin preparation machines and also several subsequent textile machines, for example a double twisting machine.
