8.6.3 Principle of the Wafflepack Changer
With the wafflepack changer on the SIPLACE 80 F it is possible to hold up to 28 wafflepack magazines and to
change these fully automatically. The magazine carriers (level) for the wafflepack magazines are numbered in
sequence from bottom to top, with the lowest number at the bottom (1 - 28).
The magazine storage unit travels vertically until the level selected lies with in the travel range of the horizontal
axis. The horizontal axis then removes the magazine carriers from the level and transports them into the
access area of the placement head.
The following Figure 8.6.2 shows the basic principle behind the wafflepack changer.

➀
The selected level of the magazine storage unit is positioned on the feeder axis (horizontal).
➁
The tray is transferred to the access area of the placement head.
➂
The components are removed.
➃
The tray is returned again.
-
The lift in the magazine storage unit brings the magazine carrier from the selected level into position on the
horizontal feeder axis.
-
The magazine carrier with the flatpack magazine is brought into the placement head's access area.
-
Once the requisite components have been removed by the placement head, the magazine is returned in
the reverse sequence of operations.
NOTE
If the placement sequence is interrupted with the wafflepack changer being switched off, the set-up and the
current fill level will remain saved in memory.
-
If the placement sequence is restarted using the set-up which was being used when the sequence was
aborted, the placement machine will be able to pick up the next component from the point where it picked
up the previous one.
