14.1 Overview
14.1.1 Functional principles
The MTC2 has two towers which work independently of one other. They each have a lifting axis and a
feed axis. The lifting axes can be set up with a large number of waffle pack trays in cassettes and
transport these vertically. The feed axes transport waffle pack trays which have been set up horizontally
to the pick-up position of the SIPLACE station.
The waffle pack trays (WPT) to be set up are placed in waffle pack tray carriers (WTC). They are then
inserted in a cassette one above the other with a small gap between each of them, and fixed in place
with the WTC interlock. The cassettes are fixed in place in the tower with the cassette interlock.
The lifting axes are moved vertically on linear carriages which are driven by a servo motor with a spindle.
The gradient of 20 degrees from the vertical axis reduces the travel range of the WTCs to the pickup
position of the SIPLACE station.
The WTCs are also moved horizontally on linear carriages which are driven by a servo motor with a belt
drive. A driver locks into the side of the WTC and moves it out of the cassette into the pick-up position.

The MTC2 shows a unit which, as a whole, can be
used as a moveable changeover table.
The MTC2 was developed for the machine
generation SIPLACE HF/HF3 and can also be
installed in the machine generation SIPLACE X.
The MTC2 can be installed in locations 2/4 of
SIPLACE X2, X3 and X4 machines.

After the SIPLACE station has picked up the necessary components out of the waffle pack tray, the WTC
is moved back into the cassette again.
The WTCs are transferred between the lifting axis and the feed axis via defined transfer and removal
positions. Safety queries from the software ensure that the cassettes and WTCs are always in the correct
location when the lifting axis and feed axis are moved.
Both towers can be set up independently of each other. While one tower is being refilled, the second can
continue to supply the SIPLACE station with components. This prevents interruptions to the placement
process. Special waffle pack trays are an exception here, since they can only be set up in one of the
towers.
The MTC2 can be docked onto the SIPLACE station instead of a component trolley. A separate docking
frame accepts the MTC2 and fixes it in place with two alignment pins. The exact position is measured
by two camera fiducials during the SIPLACE station reference run. The MTC2 can be moved on its own
wheels for replacement.
The system is adapted to the different standard heights (Europa and SMEMA) during the initial setup
phase, but can still be changed later without additional tools being required. The height is adjusted with
a crank mechanism when the machine is docked onto the SIPLACE station.
14.1.2 Occupying and numbering the tower
14-3: Numbering of levels in tower 1 and tower 2
You can set up and fully automatically change up
to 100 JEDEC waffle pack trays in WTCs with the
MTC2 on the SIPLACE station. The levels for the
waffle pack trays are numbered for each tower,
from the bottom to the top (1-30 for tower 1 and 1-
40 for tower 2). Only every second or third level is
occupied if higher waffle pack trays are used (high
JEDEC waffle pack trays or special waffle pack
trays).
The lifting axis on tower 1 can accommodate 5
cassettes with up to 6 WTC XLs each. Either two
JEDEC waffle pack trays or any number of special
waffle pack trays can be accommodated in a WTC
XL.
The lifting axis on tower 2 can accommodate 4
cassettes with up to 10 WTCs each. A single
JEDEC waffle pack tray can be accommodated in
a WTC.
