FEEDER STATION :
A gravity feeder houses the parts in a column. Each part is ejected by a pneumatic cylinder. The correct orientation of the part is verified using a cylinder with a plunger after verification, pneumatic cylinder moves the work-piece to the final position. Otherwise, a single acting cylinder removes the work-piece via the evacuation ramp. Further the work-piece is moved to Inspection Station.
INSPECTION STATION :
An Inspection Stations Measures the Height of the work-piece by measurement by Linear Variable Displacement Transducer. The correct dimension work-piece is processed further to Buffer Station and the wrong one is rejected.
BUFFER STATION :
The Buffer can buffer and separate up to five work-pieces. Diffuse sensors at the beginning of the conveyor detect the inserted work-piece. Light barriers upstream and downstream of the separator control the process: If the transfer point is free, the separator passes on a work-piece. The separator is actuated by a short-stroke cylinder with a deflecting mechanism. The end positions of the short-stroke cylinder are detected by means of end-position sensors. The work-piece is transferred to Process Station.
PROCESS STATION :
In the Processing station, work-piece are tested and processed on a rotary indexing table. The rotary indexing table is driven by a DC motor. The table is positioned by a relay circuit, with the position of the table being detected by an inductive sensor. On the drilled in two parallel processes. A solenoid probe with an inductive sensor checks that the work-pieces are inserted in the correct position. During drilling, the work-piece is clamped by a solenoid actuator. Finished work-pieces are passed on via the sorting gate to Sorting Station.
SORTING STATION :
This station sorts work-pieces onto three slides. Work-Pieces placed on the start of the conveyor are detected by a diffuse sensor. A pneumatic stopper with integrated valve stops the work-piece before the sorting process. Sensors upstream of the stopper detect the work-piece features (black, red, metal). The cylindrical work-pieces are sorted onto the appropriate slides via electric deflectors. A retro-reflective sensor monitors the fill levels of the slides. |
