Abstract

The top tab housing machine, run by a sensing circuit, selects (in increments of four) housings to be inserted on printed circuit cards. The circuit enhances overall speed and thru-put of the machine by decreasing the problems of the original design requiring maintenance. Reliability is improved as well.

Top Tab Housing Machine Solenoid Select and Control Card

The top tab housing machine, run by a sensing circuit, selects (in increments of four) housings to be inserted on printed circuit cards. The circuit enhances overall speed and thru-put of the machine by decreasing the problems of the original design requiring maintenance. Reliability is improved as well.

The housings come out of a dual-track feedbowl in either a forward or reverse direction. The circuit (Fig. 1) looks at four input program switches 11 that have been set to the desired sequence. The timing action (Fig. 2) of Timer 3 will select a housing. As the housing is dropped into the common track, it activates an optical sensor which resets Timer 3. Every time Timer 3 outputs a pulse, it triggers the 4-bit shift register 12 to the next output line and will look at the second switch, etc. This sequence will continue for four housings and revert back to the first housing. It will run until the 4th position sensor line 13 is activated, meaning the track can hold no more housings. As the operator inserts four housings onto a card, the circuit automatically selects 4 more. The run/hold switch 14 stops the sequence, and when put back into the run mode, automatic was halted. Initial power-up of the machine always starts with the first housing, by virtue of the power on the reset circuit and Timer 2.
