9.8.1 Segment Versions V1 and V2

At the present time you can use two different segment versions at the revolver head:

–

Segment version 1, designated E5.2 and

–

segment version 2, designated E6.1

NOTE

When performing servicing or routine maintenance work, make absolutely sure that you use only the spare

parts for the installed segment version. You must not use Version I spares with Version II segments, and vice

versa.

Differences between segment versions V1 and V2 (Fig. 9.8.2)

The above table shows the most important differences between Versions 1 and 2!

The modified nozzle seating in Version 2 means that so-called "long" nozzles can be used. With these

nozzles the placement shadow can be reduced and components as tall as 6 mm can be placed.

NOTE

This change in the design of the nozzle seating means that only nozzles for the version in question can be

used (in other words, nozzles are version-specific).

9.8.2 Structure and Functioning of Segment Version 1

Fig. 9.8.3 shows in exploded view the components of the Version 1 segment. It basically consists of the

following components:

–

Segment body

–

2 linear ball bearings for guiding the segment along the guide shaft of the revolver head

–

Sealing piston Version 1 with bronze bush as sealing slide bush. The bronze bush slides along the vacuum

tube of the revolver head and seals off the vacuum duct.

–

Pretensioning block, pretensioning plate for guidance along the revolver head web, and pin for lifting the

ball cage when the lifting slide raises the segment from the lower position in revolver head station 1 into

the upper position so that the revolver head can cycle on.

–

Miniature ball bearing

During the rotational movement of the revolver head this bearing slides along the arc guides. In revolver

head stations 1 and 7 the arc guides are not continuous - that is, they have gaps:

●

In revolver head station 7 the segments can be installed or removed.

●

In revolver head station 1 the miniature ball bearing slides into the segment claw of the lifting slide

where it is lowered for picking-up and inserting components and then raised back into the top position

in order to cycle on the revolver head.

–

Sleeve complete, consisting of

●

Preassembled sleeve with nozzle seating for Version 1 nozzles

●

Scale disk (incremental disk) for determination of the rotational angle and zero pulse at turning

stations dp1 and dp2

●

Protective ring and anti-dazzle foil for the scale disk

–

Lower deep-grooved ball bearing, friction wheel, spacer ring, spring lock washer and top deep-grooved

ball bearing are slid onto the sleeve and fixed in place with the slotted nut.

The feed motor of the turning station swings the turning station up to the segment, until the drive o-ring

touches the friction wheel of the segment. The o-ring transmits the rotational movement of the drive motor

onto the friction wheel and thus onto the sleeve with nozzle.
