3.4.6 Using the tray unit-LT and LTC
The tray unit-LT/LTC uses two magazines, allowing it to handle many parts for production
and perform part resupply during production. Four operation modes are available for use
depending on the production type. Use each type according to your needs.
Required items
See below for the supported software for each tray unit.
Operation mode selection
Select the operation mode that best suits the production type by referring to the following
chart.

Which is prioritized?
How many slots
are required for
production?
You want to reduce
changeover time because
changeover is performed
frequently
> More than 12 slots
You want to reduce downtime
during part resupply to improve
production efficiency
What is the supply
method?
* Reduce changeover time
* Improve production
efficiency
You do not want partially
used trays and want to
supply parts after they
have run out.
You don't care if partially
used trays occur.

> Reduce changeover time

Usable slots
LT: 9 slots
LTC: 10 slots
You want to produce while
minimizing downtime.
Because there is only one
part type, you want to load
them on many trays to make
the time between resupply
as long as possible.

Mode 3 This mode optimizes the job so that tray
exchange is minimized during
changeover. Several jobs are created
in the production schedule and then
tray allocation is optimized using Multi

Mode 4 One of the magazines is used for parts
resupply and the other is used for
production. When parts run out at the
production magazine, the drawer with
the empty tray is unloaded to slot 12 of
the resupply magazine. A new tray is
then moved from the resupply
magazine to a slot in the production
magazine and then production
continues.
