Abstract

A manufacturing process switch with a housing consisting of a first member and a second member. The first member is rotatable from a closed position to an open position. A proximity sensor is secured to the housing that detects the proximity of the first member to the second member and generates a signal when the first member is in the open position. An engagement device is secured to the housing for retaining the first member to the second member in the closed position. A cable attachment mechanism is attached to the first member of the housing and securable to a cable of a tool. The first member is rotatable from the closed position to the open position when a breakaway force is applied to the cable attachment mechanism. The manufacturing process is stopped when the first member is in the open position.

First claim

What is claimed is:

1. A manufacturing process switch comprising:
a housing comprising a first member rotatably coupled to a second member; the first member is rotatable between a closed position and an open position;
a proximity sensor that detects a proximity of the first member to the second member and generates a signal when the first member is in the open position;
a cable attachment mechanism secured to the housing that is securable to a cable of a tool; and
an engagement device secured to the housing that retains the first member to the second member in the closed position, wherein the first member is rotatable from the closed position to the open position when a breakaway force is applied to the cable attachment mechanism.

2. The manufacturing process switch according to claim 1 , wherein the first member is rotatably attached to the second member with a hinge.

3. The manufacturing process switch according to claim 1 , wherein the proximity sensor includes a first portion that is embedded in the first member.

4. The manufacturing process switch according to claim 1 , comprising a manufacturing process in electrical communication with the proximity sensor; wherein the manufacturing process is stopped when the first member is in the open position and the manufacturing process is operational when the first member is in the closed position.

5. The manufacturing process switch according to claim 4 , comprising a controller in communication with the proximity sensor; wherein the controller stops operations of the manufacturing process when the proximity sensor detects the first member is in the open position.

6. The manufacturing process switch according to claim 5 , wherein a second portion is connected to the controller.

7. The manufacturing process switch according to claim 1 , wherein the cable attachment mechanism is secured to the first member and includes a slotted area for securing the cable of a tool.

8. The manufacturing process switch according to claim 1 , wherein the engagement device includes at least one magnet embedded in the first member and the second member.

9. The manufacturing process switch according to claim 8 , wherein the magnets in the first member and the second member create a magnetic force requiring a predetermined breakaway force to rotate the first member to the open position.

10. The manufacturing process switch according to claim 1 , wherein the engagement device includes at least one catch mounted on the first member or the second member and one corresponding probe mounted on the opposing member of the housing.

11. The manufacturing process switch according to claim 10 , wherein the catch is spring loaded so a predetermined force is required to insert the probe into the catch or remove the probe from the catch.

12. The manufacturing process switch according to claim 1 ; wherein the first member is in the open position causing the first portion of the proximity sensor to lose the expected signal from the second portion of the proximity sensor and communicate to the controller to stop the manufacturing process.

13. The manufacturing process switch according to claim 1 ; wherein the first member is in the open position causing the first portion of the proximity sensor to lose the expected signal from the second portion of the proximity sensor and communicate to the controller to stop the manufacturing process.

14. A manufacturing system comprising:
a conveyor;
a controller for regulating movement of the conveyor;
a manufacturing process switch in communication with the controller;
a tool with a cable including at least a power tool with a power cord and a pneumatic tool with an air hose is coupled to the manufacturing process switch; and
a proximity sensor for communicating a conveyor stopping signal to the controller when the tool with a cable is moved an abnormal distance away from the manufacturing process switch.

15. The manufacturing system of claim 14 , wherein the tool with cable is coupled to the manufacturing process switch with a cable attachment mechanism.

16. The manufacturing system of claim 14 , wherein the manufacturing process switch includes a housing with a first member rotatably coupled to a second member.

17. The manufacturing system of 16 , wherein the manufacturing process switch includes an engagement device secured to the housing that retains the first member to the second member in the closed position until a breakaway force is applied from the tool with a cable.

18. A manufacturing process switch comprising:
a housing comprising a first member rotatably attached to a second member using a spring loaded hinge; the first member is rotatable from a closed position to an open position;
a proximity sensor secured to the housing that detects the proximity of the first member to the second member and generates a signal when the first member is in the open position; and
a cable attachment mechanism secured to the first member that is securable to a cable of a tool; wherein the first member is rotatable from the closed position to the open position when a breakaway force is applied to the cable attachment mechanism.

19. The manufacturing process switch of claim 18 , wherein the spring loaded hinge requires a predetermined breakaway force in order for the first member to rotate to the open position.

20. The manufacturing process switch of claim 18 , comprising a manufacturing process in electrical communication with the proximity sensor; wherein the manufacturing process is stopped when the first member is in the open position and the manufacturing process is operational when the first member is in the closed position.
