Method and apparatus for orientating a fastening element
View Patent ↗A receptacle which is configured to receive a fastener element having a hexagon, or some other polygonal profile, and which is configured to rotationally or angularly orientate the insert fastener element. One version of the receptacle provides that the receptacle is in the open position as a fastener element is dropped therein. Then, a jaw cylinder closes the receptacle, thereby orientating the fastener element. Another version of the receptacle uses springs instead of a jaw cylinder, and orientates the fastener element upon rotation of a threaded shaft of a pulling head.
1. An apparatus for orientating a fastening element comprising a plurality of jaws, each having a recess which collectively form a pocket for receiving the fastening element, wherein at least one of said jaws is moveable relative to at least one other jaw such that the pocket is closeable on the fastening element, wherein the recess of at least one of the jaws is configured to engage the fastening element and produce rotational movement of the fastening element as the pocket closes on the fastening element, further comprising means to shuttle the jaws back and forth between a device which feeds fastening elements to the pocket and a device which removes fastening elements from the pocket, after a rotational position of the fastening element has been changed by the apparatus.
2. An apparatus as recited in claim 1 , wherein the plurality of jaws comprise a pair of jaws, each having a recess which collectively form a pocket.
3. An apparatus as recited in claim 2 , wherein one of the jaws is stationaly, and the other jaw is moveable relative to the stationary jaw to effect opening and closing of the pocket.
4. An apparatus as recited in claim 2 , wherein one of the jaws has a recess which is semi-circular.
5. An apparatus as recited in claim 2 , wherein one of the jaws has a recess which is semi-hexagonal.
6. An apparatus as recited in claim 2 , wherein one of the jaws has a recess which is semi-circular and the other jaw has a recess which is semi-hexagonal.
7. An apparatus as recited in claim 2 , wherein one of the jaws is stationary, and the other jaw is moveable relative to the stationary jaw to effect opening and closing of the pocket, and wherein the moveable jaw is connected to a cylinder which actuates to move the moveable jaw back and forth.
8. An apparatus as recited in claim 1 , wherein at least one of the jaws is spring-biased relative to the at least one other jaw.
9. A method for orientating a fastening element comprising:
providing an apparatus which comprises a plurality of jaws, each having a recess which collectively form a pocket for receiving the fastening element, wherein at least one of said jaws is moveable relative to at least one other jaw such that the pocket is closeable on the fastening element, wherein the recess of at least one of the jaws is configured to engage the fastening element and produce rotational movement of the fastening element as the pocket closes on the fastening element; positioning the fastening element in the pocket; and closing the pocket on the fastening element, thereby producing rotational movement of the fastening element in the pocket.
10. A method as recited in claim 9 , further comprising providing that the plurality of jaws comprise a pair of jaws, each having a recess which collectively form a pocket.
11. A method as recited in claim 10 , further comprising providing that one of the jaws is stationary, and the other jaw is moveable relative to the stationary jaw to effect opening and closing of the pocket.
12. A method as recited in claim 10 , further comprising providing that one of the jaws has a recess which is semi-circular.
13. A method as recited in claim 10 , further comprising providing that one of the jaws has a recess which is semi-hexagonal.
14. A method as recited in claim 10 , further comprising providing that one of the jaws has a recess which is semi-circular and the other jaw has a recess which is semi-hexagonal.
15. A method as recited in claim 10 , further comprising providing that one of the jaws is stationary, and the other jaw is moveable relative to the stationary jaw to effect opening and closing of the pocket, further comprising shuttling the jaws back and forth between a device which feeds fastening elements to the pocket and a device which removes fastening elements from the pocket, after a rotational position of the fastening element has been changed by the apparatus.
16. A method as recited in claim 10 , further comprising providing that one of the jaws is stationary, and the other jaw is moveable relative to the stationary jaw to effect opening and closing of the pocket, and using a cylinder to move the moveable jaw relative to the stationary jaw.
17. A method as recited in claim 10 , further comprising providing that at least one of the jaws is spring-biased relative to the at least one other jaw.
18. A method as recited in claim 9 , further comprising shuttling the jaws back and forth between a device which feeds fastening elements to the pocket and a device which removes fastening elements from the pocket, after a rotational position of the fastening element has been changed by the apparatus.
19. A system for orientating a fastening element comprising: an apparatus comprising a plurality of jaws, each having a recess which collectively form a pocket for receiving the fastening element, wherein at least one of said jaws is moveable relative to at least one other jaw such that the pocket is closeable on the fastening element, wherein the recess of at least one of the jaws is configured to engage the fastening element and produce rotational movement of the fastening element as the pocket closes on the fastening element, further comprising a fastener feeding device which feeds fastening elements to the pocket, a fastener removing device which removes fastening elements from the pocket, after a rotational position of the fastening element has been changed by the apparatus, and means to shuttle the jaws back and forth between the fastener feeding device and the fastener removing device.
20. A system as recited in claim 19 , wherein the plurality of jaws comprise a pair of jaws, each having a recess which collectively form a pocket.
21. A system as recited in claim 20 , wherein one of the jaws is stationary, and the other jaw is moveable relative to the stationary jaw to effect opening and closing of the pocket.
22. A system as recited in claim 20 , wherein one of the jaws has a recess which is semi-circular and the other jaw has a recess which is semi-hexagonal.
23. A system as recited in claim 20 , wherein one of the jaws is stationary, and the other jaw is moveable relative to the stationaiy jaw to effect opening and closing of the pocket, and wherein the moveable jaw is connected to a cylinder which actuates to move the moveable jaw back and forth.
