Abstract

A voltage signal adaptor includes a housing, a die cable extending outward from the housing and terminating at a die cable end engageable with a manufacturing die comprising one or more die sensors, and a cable receptacle communicatively coupled to the die cable. The cable receptacle is engageable with a bolster cable of a machine press communicatively coupled to a press line programmable logic controller. The voltage signal adaptor further includes a step down power supply positioned between and communicatively coupled to the cable receptacle and the die cable and one or more signal conversion switches positioned between and communicatively coupled to the cable receptacle and the die cable.

First claim

What is claimed is:

1. A voltage signal adaptor comprising:
a housing;
a die cable extending outward from the housing and terminating at a die cable end engageable with a manufacturing die comprising one or more die sensors;
a cable receptacle communicatively coupled to the die cable, wherein the cable receptacle is engageable with a bolster cable of a machine press communicatively coupled to a press line programmable logic controller;
a step down power supply positioned between and communicatively coupled to the cable receptacle and the die cable; and
one or more signal conversion switches positioned between and communicatively coupled to the cable receptacle and the die cable.

2. The voltage signal adaptor of claim 1 , wherein the step down power supply is configured to convert an alternating current control signal into a direct current control signal.

3. The voltage signal adaptor of claim 1 , wherein the one or more signal conversion switches are configured to convert a direct current sensor signal into an alternating current sensor signal.

4. The voltage signal adaptor of claim 1 , wherein the one or more signal conversion switches comprise an open position and a closed position and are actuatable between the open position and the closed position, upon receipt of a direct current sensor signal output by the one or more die sensors.

5. The voltage signal adaptor of claim 1 , further comprising one or more signal indicator lights.

6. The voltage signal adaptor of claim 1 , wherein the one or more die sensors comprise one or more proximity sensors and one or more gas sensors.

7. A method of communicatively coupling a manufacturing die and a press line programmable logic controller, the method comprising:
positioning the manufacturing die on a machine press, wherein the machine press comprises a bolster cable and the manufacturing die comprises one or more die sensors;
providing a voltage signal adaptor comprising:
a housing;
a die cable engageable with the manufacturing die;
a cable receptacle communicatively coupled to the die cable and configured to receive the bolster cable;
a step down power supply positioned between and communicatively coupled to the cable receptacle and the die cable; and
one or more signal conversion switches positioned between and communicatively coupled to the cable receptacle and the die cable;

coupling the die cable to the manufacturing die;
coupling the bolster cable to the cable receptacle;
outputting, using the press line programmable logic controller, an alternating current control signal; and
converting, using the step down power supply, the alternating current control signal into a direct current control signal.

8. The method of claim 7 , further comprising:
outputting, using the one or more die sensors, a direct current sensor signal; and
converting, using the one or more signal conversion switches, the direct current sensor signal into an alternating current sensor signal.

9. The method of claim 7 , wherein the one or more die sensors comprise one or more proximity sensors configured to detect the presence of a workpiece within a workspace of the manufacturing die and output a direct current sensor signal when the workpiece is positioned in the workspace.

10. The method of claim 7 , wherein:
the manufacturing die comprises a gas spring positioned within a workspace of the manufacturing die;
the one or more die sensors comprise a gas sensor communicatively coupled to the gas spring positioned in the workspace of the manufacturing die; and
the gas sensor is configured to output a direct current sensor signal corresponding with the operation of the gas spring.
