Abstract

A die compatibility adaptor including a housing and a die cable extending outward from the housing and terminating at a die cable end engageable with a manufacturing die that includes a first proximity sensor configured to output a first proximity signal and a second proximity sensor configured to output a second proximity signal. The die compatibility adaptor further includes a direct cable receptacle communicatively coupled to the die cable, a duplicate cable receptacle, and one or more isolation relays positioned between and communicatively coupled to the duplicate cable receptacle and the die cable, the one or more isolation relays having a closed position and an open position. In the closed position, the duplicate cable receptacle is communicatively coupled to the die cable.

Claims

1. A machine press system comprising:

a machine press comprising a first bolster cable and a second bolster cable;

a manufacturing die coupled to the machine press, the manufacturing die comprising a first proximity sensor configured to sense the presence and absence of a first workpiece within a first workspace and a second proximity sensor configured to sense the presence and absence of a second workpiece within a second workspace; and

a die compatibility adaptor comprising;

a housing;

a die cable extending outward from the housing and terminating at a die cable end engageable with the manufacturing die;

a direct cable receptacle communicatively coupled to the die cable and configured to receive the first bolster cable;

a duplicate cable receptacle configured to receive the second bolster cable; and

one or more isolation relays positioned between and communicatively coupled to the duplicate cable receptacle and the die cable, the one or more isolation relays comprising a closed position and an open position, wherein in the closed position the duplicate cable receptacle is communicatively coupled to the die cable.

2. The machine press system of claim 1, wherein the first bolster cable and the second bolster cable are communicatively coupled to a press line programmable logic controller.

3. The machine press system of claim 1, wherein the one or more isolation relays are actuated into the closed position when the second bolster cable is engaged with the duplicate cable receptacle.

4. The machine press system of claim 1, wherein the manufacturing die further comprises a die communications module communicatively coupled to the first proximity sensor and the second proximity sensor and wherein the die cable is engageable with the die communications module.

5. The machine press system of claim 1, wherein the first proximity sensor is positioned within the first workspace of the manufacturing die and the second proximity sensor is positioned within the second workspace of the manufacturing die.

6. The machine press system of claim 5, wherein the first proximity sensor outputs a first proximity signal when the first workpiece is positioned within the first workspace and the second proximity sensor outputs a second proximity signal when the second workpiece is positioned within the second workspace.

7. The machine press system of claim 1, wherein the one or more isolation relays each comprise a solid state relay.

8. A method of communicatively coupling a manufacturing die and a machine press, the method comprising:

positioning a manufacturing die on a machine press, wherein the machine press comprises a first bolster cable and a second bolster cable and the manufacturing die comprises a first proximity sensor configured to sense the presence and absence of a first workpiece within a first workspace and a second proximity sensor configured to sense the presence and absence of a second workpiece within a second workspace;

providing a die compatibility adaptor comprising;

a housing;

a die cable engageable with the manufacturing die;

a direct cable receptacle communicatively coupled to the die cable and configured to receive the first bolster cable;

a duplicate cable receptacle configured to receive the second bolster cable; and

one or more isolation relays positioned between and communicatively coupled to the duplicate cable receptacle and the die cable, the one or more isolation relays comprising a closed position and an open position, wherein in the closed position the duplicate cable receptacle is communicatively coupled to the die cable;

coupling the die cable to the manufacturing die;

coupling the first bolster cable to the direct cable receptacle; and

coupling the second bolster cable to the duplicate cable receptacle.

9. The method of claim 8, wherein coupling the die cable to the manufacturing die and coupling the first bolster cable to the direct cable receptacle communicatively couples the first proximity sensor and the second proximity sensor of the manufacturing die with the first bolster cable.

10. The method of claim 8, wherein coupling the second bolster cable and the duplicate cable receptacle actuates the one or more isolation relays into the closed position such that the first proximity sensor and the second proximity sensor of the manufacturing die are communicatively coupled with the second bolster cable.

11. The method of claim 8, wherein the first proximity sensor is configured to output a first proximity signal when the first workpiece is positioned within the first workspace of the manufacturing die and the second proximity sensor is configured to output a second proximity signal when the second workpiece is positioned within the second workspace of the manufacturing die.

12. The method of claim 11, wherein the die compatibility adaptor is configured to split the first proximity signal and the second proximity signal such that the direct cable receptacle and the duplicate cable receptacle each receive portions of the first proximity signal and the second proximity signal.
