The rotational movement of the screwdriver is restricted by the stop nipple on the face of the motor gear-

wheel. After each rotation of 180° the stop nipple will lie up against the stop. The screwdriver is fixed in the

end position by a holding current.

Screwdriver unit 2 is activated as soon as the end message of the dR revolver head axis for "Revolver head

division reached" is received.

The rotational movement for the open or closed segment is determined similarly to the procedure shown in

Fig. 9.5.11.

9.5.8 Circular Arc Guidance for the Segments

The circular arc guide holds the segments at a defined clearance from the revolver head center point which is

also the center of rotation. While the revolver head turns the segment ball bearings roll along the circular inner

faces of the fixed and removable circular arc guides (link). There are breaks in the circular arc guides in each

case at the top, that is, at revolver head station 7 and at the bottom, that is, at revolver head station 1.

You can insert or remove the segments at revolver head station 7. In revolver head station 1, the pick-up and

placement station the lifting slide moves the segment vertically once the ball bearing of the segment has

moved into the segment claw.

The circular arc guide consists of two halves:

–

one guide integrated into the lifting slide housing and

–

a removable guide (link).

It is fastened with two M2.5 countersunk screws to the lifting slide housing. Two parallel pins center the

removable circular arc guide (see Fig. 9.5.14).
