Dann wird nach Entfernen der Hebevorrichtung 25 die Hülse 2 entlang des Ablagebalkens 9 in Richtung zum Zylinder 1 verschoben. Dabei stellen die Zentrierleisten 12 sicher, dass die Hülse 2 die richtige Stellung gegenüber dem Kopfstück 8 und damit gegenüber dem Zylinder 1 einnimmt.When mounting a sleeve 2 on the cylinder 1, the movement processes run in reverse order. First, the sleeve 2 by means of Lifting device 25 brought into the position 2 'shown in Figure 2. Subsequently the head piece 8 with the angled tee 14 behind the flange 22 attached, and by pivoting in the direction of the arrow 24 'so far moved until the balls 20 of the pressure pins 13 partially in the wells 24 engage and the latch 15 behind the flange 22 occurs. Then, after removal of the lifting device 25, the sleeve 2 along the Storage bar 9 is moved in the direction of the cylinder 1. Here are the Centering 12 sure that the sleeve 2 the right position opposite the head piece 8 and thus against the cylinder 1 occupies.

Das Ausführungsbeispiel gemäß Figur 3 und 5 weist ein Kopfstück 8 und einen Ablagebalken 9 auf, die in gleicher Weise wie beim ersten Ausführungsbeispiel ausgebildet sind und daher nicht nochmals beschrieben werden. Zusätzlich ist ein insgesamt mit 26 bezeichneter Greifer vorgesehen, der ein Greifergehäuse 27 aufweist. Das Greifergehäuse 27 steht in Eingriff mit einer Gewindespindel 28, die mittels eines Handrades 29 drehbar und in nicht dargestellter Weise am Ablagebalken 9 gehalten ist. Durch Betätigung des Handrades 29 kann das Greifergehäuse 27 mit dem Greifer 26 in bzw. entgegen der Richtung des Pfeiles 40 bewegt werden.The embodiment according to FIGS. 3 and 5 has a head piece 8 and a storage bar 9, in the same manner as in the first embodiment are formed and therefore will not be described again. In addition, a gripper designated overall by 26 is provided, which has a gripper housing 27. The gripper housing 27 is engaged with a threaded spindle 28 which rotates by means of a hand wheel 29 and in not shown manner is held on the shelf bar 9.
