Abstract

A remote control system operates automated equipment, such as a robotic device. The remote control system operates using an RF link and has both a "hard stop" control and a "soft stop" or "cycle hold" control. The system permits the technician or operator to work around a robotic device with the proximity switches deactivated without the necessity of being connected to the main control panel using a pendant device connected by cables.

Claims

1. A control unit for automated equipment having hard stop and soft stop controls comprising:

an RF receiver capable of receiving two different RF signals from a transmitter;

a momentary contact relay means comprising a first relay operator and first relay contacts, the first relay operator connected to the receiver to be energized in response to the receipt of one of the two RF signals, the first relay contacts connected to the hard stop control of the automated equipment;

a latch relay means comprising a second relay operator and a second relay contacts, the second relay operator connected to the receiver to be energized in response to the receipt of the other of the two RF signals, the second relay contacts connected to the soft stop control of the automated equipment, the second relay operator connected to the second relay contacts to disable the second relay operator after it has been energized;

reset switch means connected to the second relay operator to energize the second relay operator independently of the receiver; and

override switch means connected to the second relay operator to permit the second relay operator to be reenergized in response to the receipt of said other of the two RF signals.

2. A control unit as defined in claim 1 comprising in addition test switch means for deactivating the automated equipment controls from the first and second relay contacts.

3. A control unit as defined in claim 1 comprising in addition indicator lights connected to the first and second relay contacts for indicating the energizing of the first and second relay operators.

4. A remote control system for automated equipment having hard stop and soft stop controls comprising:

a portable RF transmitter capable of selectively sending two different RF signals;

an RF receiver capable of receiving the two different RF signals from the transmitter;

a momentary contact relay means comprises a first relay operator and first relay contacts, the first relay operator having two terminals, one of the terminals of the first relay operator being connected to the receiver to be energized in response to the receipt of one of the two RF signals, the first relay contacts connected to the hard stop control of the automated equipment;

a latch relay means comprising a second relay operator and second relay contacts, the second relay operator having first and second terminals, the first terminal of the second relay operator connected to the receiver to be energized in response to the receipt of the other of the two RF signals, the relay contacts connected to the soft stop control of the automated equipment, the second terminal of the second relay operator connected to the second relay contacts to disable the second relay operator after it has been energized;

reset switch means connected to both terminals of the second relay operator to energize the second relay operator independently of the receiver and the second relay contacts; and

override switch means connected to the second terminal of the second relay operator to permit the second relay operator to be re-energized in response to the receipt of said other of the two RF signals.

5. A remote control system as defined in claim 4 comprising in addition test switch means for deactivating the automated equipment controls from the first and second relay contacts.

6. A remote control system as defined in claim 4 comprising in addition indicator lights connected to the first and second relay contacts for indicating the energizing of the first and second relay operators.

7. An automated equipment control system comprising:

a power supply system having first and second power supply lines;

an automated equipment having controls for a recyclicable soft stop and a final hard stop;

a portable transmitter unit adapted to be carried by a technician when programming the automatic equipment, the transmitter unit having a transmitter capable of sending two different RF signals, the transmitter unit also having a portable electric power supply; and

a control unit connected to the automatic equipment and to the power supply system, the control unit including an RF receiver capable of receiving the two different RF signals from the transmitter, the control unit also including a momentary contact relay means having a first relay operator and first relay contacts, the first relay operator having first and second terminals, the first terminal of the first relay operator being connected to the first power supply line through the receiver and the second terminal of the first relay operator being connected to the second power supply line to be energized in response to the receipt of one of the two RF signals by the receiver, the first relay contacts being connected to the hard stop control of the automated equipment, the control unit also including a latch relay means having a second relay operator and second relay contacts, the second relay operator having first and second terminals, the first terminal of the second relay operator connected to the first power supply line through the receiver to be energized in response to the receipt of the other of the two RF signals, the second relay contacts being connected to the soft stop control of the automated equipment, the second terminal of the second relay operator connected to the second power supply line through the second relay contacts to disable the second relay operator after it has been energized.

8. An automated equipment control system as defined in claim 7 wherein the control unit includes in addition reset switch means connected to both terminals of the second relay operator and to both the first and second power supply lines to energize the second relay operator independently of the receiver and the second relay contacts.

9. An automated equipment control system as defined in claim 7 wherein the control unit includes in addition override switch means connected between the second terminal of the second relay operator and the second power supply line to permit the second relay operator to be energized in response to the receipt of said other of the two RF signals.

10. An automated equipment control system as defined in claim 7 wherein the control unit includes in addition test switch means for disconnecting the controls of the automated equipment from the first and second relay contacts.

11. An automated equipment control system as defined in claim 7 wherein the control unit includes in addition indicator lights connected to the first and second relay contacts for indicating the energizing of the first and second relay operators.
