Abstract

The invention relates to a conveying device for conveying electrical or optical lines (8) such as wires, cables, line bundles, optical fibers etc. comprising a gripper (3) for gripping a line (8), wherein the gripper (3) is displaceable along a guide (1) between a first position (5) and a second position (6), characterized in that in the region of the first position (5) and in the region of the second position (6), respectively one active interface is provided which is configured to come into operative communication with the gripper (3) and bring this into a closed position or open position when the gripper (3) is located in one of the two positions (5, 6).

Claims

1. A line conveying machine comprising:

a gripper;

a carriage, said gripper being mounted on said carriage;

a guide, said carriage being displaceable on said guide along a first path between a first position and second position;

a carriage drive operatively connected to said carriage to controllably displace said carriage with said gripper along said first path;

an actuating mechanism configured to actuate said gripper, said actuating mechanism being mounted on said carriage to travel between said first and second positions;

a first active interface situated proximate to said first position, said first active interface communicating motive energy to said gripper in a region of said first position to bring said gripper into closed position;

a second active interface situated proximate to said second position, said second active interface communicating motive energy to said gripper in a region of said second position to bring said gripper into open position;

a base, said base having a first part, said base having a second part, said second part being controllably displaceable relative to said first part along a second path substantially parallel to said first path;

said guide, said carriage, said first active interface, and said gripper being situated on said first part of said base; and

,

said second active interface being situated on said second part of said base so that said gripper controllably drives said second part of said base relative to said first part of said base via said second active interface.

2. A line conveying machine as claimed in claim 1, further comprising:

a selectively releasable brake locking said second part against displacement relative to said first part.

3. The line conveying machine as claimed in claim 1, wherein:

said second part is mounted on said guide.

4. A line conveying machine as claimed in claim 1, further comprising:

a receiving station receiving lines at said first position; and

,

a dispensing station dispensing lines at said second position.

5. A line conveying machine comprising:

a gripper;

a guide, said gripper being displaceable along said guide along a first path between a first position and a second position;

an actuating mechanism configured to actuate said gripper, said gripper and said actuating mechanism being operatively movably mounted on said guide to travel between said first and second positions;

a first active interface communicating motive energy to said gripper in a region of said first position to bring said gripper into closed position, said first active interface situated proximate to said first position; and

,

a second active interface communicating motive energy to said gripper in a region of said second position to bring said gripper into open position, said second active interface situated proximate to said second position.

6. A line conveying machine as claimed in claim 5, further comprising:

a mechanical actuator in said first active interface, said mechanical actuator driving said actuating mechanism and said gripper.

7. A line conveying machine as claimed in claim 5, further comprising:

a mechanical actuator in said second active interface, said mechanical actuator driving said actuating mechanism and said gripper.

8. A line conveying machine as claimed in claim 5, further comprising:

a fluid-powered cylinder-piston unit located in at least one of said first and second active interfaces, said cylinder-piston unit being in operative communication with a supply pressure controller.

9. A line conveying machine as claimed in claim 5, further comprising:

a gripper drive for said gripper, said gripper drive being displaceable together with said gripper along said guide; and

,

at least one of said first and second active interfaces includes power supply for said gripper drive.

10. The line conveying machine as claimed in claim 5, wherein:

said actuating mechanism is bistable, said actuating mechanism having stable open and closed positions, and a dead point is provided between said stable open and closed positions.

11. A line conveying machine as claimed in claim 5, further comprising:

a spring connected to exert force holding said gripper in closed state.

12. A line conveying machine as claimed in claim 5, further comprising:

a receiving station receiving lines at said first position; and

,

a dispensing station dispensing lines at said second position.

13. The line conveying machine as claimed in claim 5 wherein:

said first active interface and said second active interface are stationary in relation to said guide.

14. A line conveying machine as claimed in claim 5, further comprising:

a transfer gripper transferring line to said first gripper, said transfer gripper located proximate to said first position; and

,

a receiving gripper receiving line from said first gripper, said receiving gripper located proximate to said second position.

15. A line conveying machine as claimed in claim 5, further comprising:

a base, said base having a first part, said base having a second part, said second part being controllably displaceable relative to said first part along a second path substantially parallel to said first path;

said guide and said gripper being situated on said first part of said base; and

,

one of said first and second active interfaces being situated on said second part of said base, said gripper controllably driving said second part of said base relative to said first part of said base.

16. A method of conveying lines comprising the steps of:

positioning a gripper along a guide to reach a first position;

supplying motive energy to the gripper from a first active interface in a region of the first position;

using the supplied motive energy from the first active interface to grip a line with the gripper;

displacing the gripper and gripped line along the guide;

reaching a second position with the gripper and gripped line;

supplying motive energy to the gripper from a second active interface in a region of the second position; and

,

using the supplied motive energy from the second active interface to release the gripped line from the gripper.

17. A method of conveying lines as claimed in claim 16, further comprising the step of:

actuating the gripper mechanically to grip the line.

18. A method of conveying lines as claimed in claim 16, further comprising the step of:

actuating the gripper mechanically to release the line.

19. A method of conveying lines as claimed in claim 16, further comprising the steps of:

controllably displacing at least one of the first and second active interfaces relative to the guide along a direction substantially parallel to the direction of displacement of the gripper along the guide; and

,

effecting said step of controllably displacing at least one of the first and second active interfaces relative to the guide, by operatively coupling the gripper to drive at least one of the first and second active interfaces relative to the guide to attain a desired position.

20. A method of conveying lines as claimed in claim 19, further comprising the step of:

effecting said step of controllably displacing at least one of the first and second active interfaces relative to the guide, to vary the distance between the first and second active interfaces based on line length that is handled.
