This should be simple, but not for me. This is for a DIY edge bander.
I need a circuit using switches and relays to control a feed motor and cutter.
The feed motor is controlled with a contactor. The cutter is pnuematic and controlled by a solenoid.
The feeder is energized and pushes a board down a table applying 'tape' to the edge. The leading edge of the board encounters a SPDT switch embeded in the table top and pushes the contacts in. The feeder continues push the board down the table until the trailing edge of the board causes the switch to retract, which stops the feeder and activates the solenoid that activates the pnuematic ram to cut the tape. As the tape is cut a SPST switch opens to de-energize the solenoid to allow the pnuematic ram to return. At the same time the feeder motor is re-energized and the process repeats.
Besides the above mentioned switches, I believe the only other device needed would be a DPDT relay. That being said I have spent two days trying to draw the circuit with no success.
Any suggestions?
Thanks
