Abstract

A technique is described whereby a multiple (I/O) interconnecting unit provides power and for robotic effector devices. The unit is an over the previously used devices which required thirty-conductor interconnection cable. It is designed to higher flexibility and reliability, as well as noise immunity, than that of the previous unit.

Multiple Input/Output Unit

       A technique is described whereby a multiple (I/O)
interconnecting unit provides power and for robotic effector devices.
 The unit is an over the previously used devices which required
thirty-conductor interconnection cable.  It is designed to higher
flexibility and reliability, as well as noise immunity, than that of
the previous unit.

      The multiple I/O interconnecting unit, as shown, of a
four-conductor cable that uses four 24 AWG and a shield.  Conductor
#1 is used for the signal; Conductor #2 is used for the receive
Conductor #3 is used for ground; and Conductor #4 is for the +24 VDC
circuit.  The shielded part of the is provided for the head crash
interlock switch of the device.  A DC/DC converter converts the 24 V
source 5 V, enabling a lesser number of wires to be used and not be
sensitive to noise pick-up.

      The four-conductor cable interconnects to the unit, which is
composed of a central processing (CPU) and I/O interface circuit
board.  The I/O board is designed to accommodate up to twenty and
twenty outputs.  Its input portion has five quad- which accept 24 V
input signals from various located at the robot pick-up head.  The 24
V signals converted to 5 V signals to be fed to the CPU.  The portion
receives 5 V signals from the CPU and the signals to 24 V for driving
the solenoids of robot pick-up head.

      Two identical CPU circuit boards are required; one in the
control panel, and the other...
