1.1 Safety
1.1.1 General
The integrator installing the swivel tool changer into the system must follow the safety demands
stated in standards and provisions applicable in the country where the swivel tool changer
system is to be installed. The products are all prepared for CE-certification.
The user of the Robot System Products swivel tool changer is responsible that law and
directives applicable in respective countries, with regards to safety, are followed. The user is
also responsible to guarantee that all safety devices are installed correctly.
WARNING!
Never carry out service work on a robot that has not been taken out of operation.
See safety information for the robot.
WARNING!
Only perform work on tools attached to the swivel tool changer if the air pressure
is safely switched off.
WARNING!
Be aware that swivel tool changers and tool attachments are heavy and may
cause personal injury and equipment damage if dropped.
NOTE!
The swivel tool changer shall always be in locked position, also when empty, to
avoid unexpected locking if air pressure is lost.
WARNING!
Electric signals and power must be disconnected/switched off when docking the
tool attachment. This is to prevent sparking between signal pins and tool
attachment.
1.1.2 Explanation of warnings
The warnings in this document are specific to the products in this manual. It is expected that the
user also pay attention to certain notifications from the robot manufacturer and/or the
manufacturers of other components used in the installation.
WARNING!
The warning sign will make you aware that a situation could result in potential
serious injury or damage to equipment.
NOTE!
The note sign will alert you about something important to consider.

1.2 Description of RSP swivel tool changer
The Robot System Products’ swivel tool changer integrates the advantages of swivels and tool
changers into one single product maximizing the flexibility and productivity of the robot.
Our tool changer technology enables robots to handle and switch between multiple tools. The
principle behind the patented looking device TrueConnect™ is that load is distributed uniformly
through pressing locking balls into spherical grooves in the tool attachment. With TrueConnect™
the play is a minimum and the position repeatability is practically absolute through the lifespan.
In consequence substantially larger positional deviations are accepted when docking.
A built-in spring ensures that the tool remains in place in the swivel tool changer even if the air
pressure drops.
When using a swivel tool changer compressed air and electric signals will be directly available at
the tool without loose, hanging cables and hoses which has to be considered during
programming. The combination of RSP’s hose packages with the swivel tool changer does in
addition significantly reduce the design and installation times for the system integrator.
1.3 Complementary Equipment
Complementary equipment is described in separate documents.
Article
Note
Cable and Hose Packages
Complete packages for most robots on the market ready to be
mounted without any modifications.
Tool stand
Tool stands will, combined with tool attachments and
adaptation kits, give a rigid installation for easy tool changing.
Connection kits
In order to make electrical installation easier, connection kits
are available for the swivel tool changer.
3D-models
Available in Solid Works® and STEP-format.

2 TECHNICAL SPECIFICATIONS
2.1 Description of swivel tool changers and tool attachments
This document presents the Robot System Products STC250-6 and STC250-6E swivel tool
changer including tool attachments dedicated for material handling. Likewise presented are
adaptation kits, connection kits to facilitate electrical installation and a tool stand kit.
The swivel tool changer STC250-6 transfers compressed air to the tool. It can be equipped with
transfer of electrical signals, via spring loaded signal pins, to the tool attachment. The electrical
version is designated ’E’. The swivel tool changer STC250-6 and STC250-6E cannot transport
fluids.
The spring loaded signal pins of STC250-6E are placed and protected along a circle close to the
centre of the swivel tool changer. The signal pins are not in connection until at the very end of
the docking cycle when the tool attachment is already properly aligned. This guarantees a
minimum of wear of pins and contact surfaces.
The electrical unit can be used for identification and checking the presence of tools by using
signal jumpers and binary coding of signals on the tool attachment.
For other bolt circles adaptation plates between the swivel tool changer and the turning disc on
the robot may be needed. Such adaptation plates are available from RSP.

2.1.1 Coordinate System Definition
A swivel tool changer adds load to the robot. If the arm and tool loads are not stated correctly
during programming the behaviour of the robot and the wear of the equipment will be affected.
Information about weight and centre of gravity can, in accordance with the co-ordinate system
stated below, be found in the technical specification tables of the swivel tool changers.
NOTE!
For the swivel tool changer origo is situated on the surface in the centre of the
robot mounting flange.
