8.4 Tool parking station
The parking of the tools is carried out vertically into WALTHER standard tool parking stations
(welding guns) according to the gravity principle.
8.4.1 Gravity parking station with guiding bolt and supporting roll
Fehler! Textmarke nicht
definiert. Type 95812
Tools are parked in such a way, that the tool side of the tool changer with
the parking segments which are provided with bushes is plunged in 2 locating bolts
of the tool parking station. During the lowering/ picking up process the vertical movement
is beared up by a support device with roll to prevent a tipping. The support roll must be
adapted and adjusted when installing at the tool. Due to their dimensions gripper tools
are parked in special parking stations of the tool supplier, however, the support principle
must be maintained as well.
Caution
A parked tool side of the tool changer is to be protected against
contamination and welding chips!
WALTHER standard parking stations are designed in modular system:
- stand
- level
adjustment
- roll support
- hinged cover
- installation package electro
- installation package pneumatic
Permissible deviations during tool change:

8.4.2 Gravity parking station with doublesword guidance Type 95813
The parking technique is like item 8.4.1, only that bolts which are mounted crosswise
into the bearings of the tool side are plunged into the sword guidances of the
tool parking station. Because of this construction an additional support device as for 8.4.1 is not
necessary for most of the applications. The torque is received within the sword recepticles.
For tool loads > 300 kg an additional torque support is necessary.
8.5 Requirements on a reliable function
