1. OUTLINE AND FEATURES
This APC (automatic pallet changer) unit is based on “hydraulic unit less” system realized by VS series standard model, and is featured by its ECO, ECO (ecology and economy) specifications with high speed and high reliability. It enables men to relieve from periodic maintenance of hydraulic oil required by the conventional system and to reduce the running cost.
1-1 Configuration
1-1-1 Saddle (Pallet Table)
For the pallet clamp/unclamp action, high pressure (about 40kgf/cm2) hydraulic power converted from compressed air amplified by air hydro-unit is used. Use of air pressure for the purpose requiring high power such as pallet clamp unit has hitherto been generally considered unsuitable, however, this problem has been solved by converting air pressure energy into hydraulic pressure.
1-1-2 APC Main Unit
For the APC main unit, rotary arm type exchange system is adopted. The relative movement of a rotary arm driven by an inverter motor and two lines of groves on the pallet runs the system. Compared with the conventional hydraulic system, this system enables smoother and quicker pallet change and, furthermore, higher reliability is achieved with simple construction by reducing the number of parts nearly to a half.
1-1-3 Splash Cover
The processing area is covered with splashguard up to the ceiling as a fully enclosed space. The processing area is separated from the APC rearranging area by an automatic shutter driven by an electric motor for protection against the splash of coolant and chips.
