2.1 Short description
Transfer units are built into the STEIN300 Workpiece Transport System.
The transfer unit transfers workpiece carriers from one conveyor to another.
In conjunction with the Workpiece Transport System, the transfer unit 90°/180° ena-
bles:
•the replacement of grid-free and rectangular WTs (e. g: 160x400) between convey-
ors,
•diversion from the WT 90° to the transverse section,
•transfer from the WT 180° parallel to the main section to the
feed / return path,
•diversion of WTs to the main section.
The transfer unit 90° consists of:

For the 90° transfer unit the permitted loading is
•in the Z axis: 12 N (WT + workpiece) if load is centred and under a STEIN working
pressure of 4 bar.
For the 180° transfer unit K the permitted loading is
•in the Z axis: 12 N (WT + workpiece) if load is centred and under a STEIN working
pressure of 4 bar.
Unauthorised interventions, alterations or repairs carried out to the transfer units invali-
date the guarantee.
STEIN Automation accepts no liability for any damage caused by unauthorised interven-
tions, alterations or repairs.
3.3 Foreseeable misuse
DANGER
It is prohibited
to transport products or workpieces with the transfer unit other than those ap-
proved.
to transport parts without workpiece carriers
This can lead to unforeseeable operating conditions and related dangers.
The transfer units must not be used
•in queue mode.
•be used to stop workpiece carriers,
•be used to separate workpiece carriers
i
STEIN Automation accepts no liability for damages that might arise due to misuse of
the system.
3.4 Residual danger
DANGER
The transfer unit must be integrated in the EMERGENCY STOP circuit of the high-
er level
system controller.
The transfer units are manufactured using state-of-the-art technology and to recognised
safety standards. Nevertheless their use can lead to dangerous situations for users or
third parties or to impairments of the system and other material assets.

12 STEIN300_Umsetzer_04_GB.doc / 03.2020
WARNING
The protective guards of the lift the station may not be removed in automatic
operating mode.
There is a risk of injury if the system is operated without protective guards.
All protective equipment must always be fully installed and functioning. The pro-
tective guards may only be removed by the maintenance personnel during
maintenance and repair work.
If the transfer unit is used improperly, the following injuries can result:
WARNING
Crushing due to:
Jamming occurring between the components of the transfer unit that move line-
arly
Jamming occurring between the WT and the guide track or rails,
Getting drawn in or clothing getting wound around components.
The lift station may only be operated with or while enclosed by protective guards.
CAUTION
Hazardous areas may arise while the conveyor is in operation. There is a risk of
crushing due to
jamming between the workpiece carriers,
being drawn in and clothing being wound around components, or
the characteristics of the product being transported.
Fig. 3-2:
Possible areas for
- jamming,
- getting drawn in or cloth-
ing wound around com-
ponents.

with 90° transfer unit
2B-basic configuration
with 180° transfer
unit
A-basic configurations are equipped with 90° transfer units.
B-basic configurations are equipped with 180° transfer units.
Transfer unit 90°
The 90° transfer unit puts the WT from the main section onto the transverse section or
from the transverse section onto the main section. The 90° transfer unit is fitted
between the guide profiles of the conveyor.
Transfer unit 180o
The transfer unit 180° moves the workpiece carrier to a section that runs parallel to the
original direction of transport.
Procedure:
The WT is transported by the two transport belts until it reaches the inlet stopping device
(STEIN Automation option) or the internal stop (standard). The proximity switch located in
this position activates the elevating cylinder and the workpiece carrier is lifted up. in the
last step the WT is transferred to the transverse section.
WARNING
The transfer unit may only be operated with or while enclosed by protective
guards.
