4.2 General description
The tool change system is designed according to the modular principle. According to its
requirement it can be equipped with different or fluidic transmission elements or mechanic,
pneumatic or electro modules. The compact construction with integrated locking cylinder
enables a quick tool change of high loads at low own weight and minimum interference
contours. With reference to the robot and tool side the standard version has no interference
contours protuding over the plate thicknesses. The coupling mechanism has an automatic and
free from play lock, as a result of this the tool remains locked over a longer period also in case
of pressure drop.
An unintentional disconnection of the tool can be prevented by an optional
mechanical-pneumatical safety circuit. The disconnection energy can only be switched
on by activating a mechanical controlled valve (local control cam) whose function can be in-
quired sequentially and whose sole failure does not lead to the loss of the safety
function when designing the control accordingly.
An optional electric saftey circuit can also guarantee by means of an safety switch and the op-
erator that the energy for reswitching the valve is available in the parking position only.
Tools are preferably parked vertically into tool parking stations according to the
gravity principle. Possible parking techniques:
- gravity parking with guiding bolts and supporting roll type 95812
- gravity parking with double sword guidance type 95813.
If a malfunction occurred after a crash robot and tool side can be disconnected by means of an
emergency separation facility.
While the tool changer type Z03 can be operated in pull-in and push-pull technique
type 91489-Y10 is provided for force neutral push-pull technique.
4.3 Duly usage
The tool change system is no independent machine within the meaning of the EC machinary
guidelines and is only allowed to put into operation in case that the total facility corresponds to
the instructions of the machinary guidelines.
The tool change system is exclusively for automatic docking, disconnecting and changing of
tools at industrial robots in the area of the tool parking stations within the separating protection
units.
Outside the area of the tool parking stations a disconnection/tool change is only allowed in case
that safety is guaranteed on the basis of other measures.
Couple procedures are only allowed with depressurised fluidic elements and voltage free electro
connectors.
