Interspace divert and merge module XBUT 180 C
X85 Pallet
Function description
The Interspace module is divided into Stop position and
Return stop position.
This function supports ”non-memory transports”.(see
below)
Stop position
The RFID-reader of the Stop position identifies the pallet,
which is necessary for deciding whether the pallet should
go straight or go through the short-cut.
Single pallets or multiple simultaneous pallets are allowed
to be released downstream the straight flow, while single
pallets are allowed through the short-cut one at a time.
Return stop position
Single or multiple pallets are let downstream along the
return flow when no other pallet is on the way from the
Stop position.

Data:
Pre-stop queue pressure limit: 100 kg
Notes:
The station is not equipped with any downstream
maxqueue sensor as the design is only possible with
an overview of the line as a whole.
The sensor configuration is depending on the size of
pallet. Mixed flow with reference to pallet length is not
possible.
Non-memory transports
The ”Non-memory transport” design makes the module
less sensitive to unnormal situations as when a pallet is by
mistake lifted-off the module during a transport.
Independent of where a pallet is inside the module, it is
always detected by a sensor. It is detected from the
moment it leaves a stop. As the module monitors the
sensors directly, if a pallet is lifted off, the module auto-
recovers and release the second pallet downstream.
The alternative would be that the sensor placing is
such that it requires a memory to remember the pallet-
transport. While the memory is on, it stops the second
pallet from being released by the stop. The
disadvantage of this method is that if the pallet is lifted-
off, the memory would stay on until forever, thus never
releasing the second pallet. A situation is arisen which
could be difficult to understand and solve.
