The provided kind of operation is push-pull-technique, i.e. robot carries out couple movement
and tool changer locks the connected changer halves. Besides the valve spring forces of the
fluidic elements and the frictional forces the robot must take up no further reaction forces
(force neutral push-pull technique) in the process.
- Compressed air connection for locking unit: 6 and/or 12 bar
- max. carrying force F
T
= 25 KN ,see 2.
- Max. torque moment (robot axis 6): M
T
= 5,000 Nm
- max bending moment M
B
= 5,000 Nm
- Periodic intervals for maintenance: 800,000 up to 1.5 million couple cycles
(depending on operating conditions)
- Technical data of electro plugs, fluidic elements: see 3.
- Surrounding conditions (storage and operation condition)
temperature: +5° up to +40° C
relative humidity of air: 20 up to 80%
4.4 Obvious, improper use
- The maximum static holding load must not be exceeded. Acceleration values have to be
considered by the robot movement.
- In case of compressed air drop/failure (especially locking line) it is not allowed to work on;
it is merely allowed to finish cycle of work. The free from play lock of the coupling
mechanism is still kept in case of air pressure drop but it must not be used for automatic
and set-up operation.
- The maximum pressure for the locking unit and the fluidic elements must not be exceeded
- The maximum current and tension values for the electro plug connectors must not
be exceeded.
- The tool change system may be assembled, installed, adjusted and maintained by
authorized and skilled staff only.
- It is not allowed to modify the tool change system without any authoration
or to change it otherwise.
- Connection cables and hoses have to be provided with a tension relief which allows a
movement of the subassembly elements but not too strong tension loads.
- The tool change system may be used in the provided kind of operation only.
- The tool change system at normal operation is basically to be used only in case that all
protection units of the total system are available, regularly installed and totally operative.
- In case that there is installed a safety circuit it is not allowed to make it ineffective.
- After assembly, a crash or a repair the tool changer must only be put into operation (again) if
the faultless quality of the components and the correct function especially of the coupling
mechanism(automatic, free from play lock) was stated.
