Abstract

A cutting station for the automatic cutting to a specific length of cable elements and has a magazine which extends in a longitudinal direction and a transverse direction and has several holders for one cable element each. The cable elements are held next to each other in a horizontal magazine plane. A processing head extends in a longitudinal direction, which is movable in a transverse direction relative to the stationary magazine and is designed for gripping, pulling off and cutting to a specific length a respective currently selected cable element from the magazine. Each holder has two fixing elements spaced apart from one another in the longitudinal direction for holding the cable element. For machining by the processing head, a respective holder with a respective cable element is lifted in a preferred configuration from the magazine plane into the working plane.

First claim

What is claimed is:

1. A cutting station for automatic cutting of cable elements to a specific length, the cutting station comprising:
a magazine which extends in a longitudinal direction and a transverse direction and has a plurality of holders and each holder of the plurality of holders is formed for holding one of the cable elements, wherein the cable elements are held side by side in a magazine plane by the plurality of holders, each holder extending in the longitudinal direction; and
a processing head extending in the longitudinal direction, the processing head is adapted to be moved in the transverse direction relative to the magazine and is designed for processing, namely for gripping, pulling off and cutting to a specific length a selected cable element, the selected cable element being one of the cable elements from the magazine,
wherein each holder from the plurality of holders has two fixing elements spaced apart from one another in the longitudinal direction for holding the cable element, and
wherein the cutting station includes at least one lifting element for lifting a selected holder perpendicularly to the longitudinal direction from the magazine plane into a working plane.

2. The cutting station according to claim 1 , wherein the processing head includes the at least one lifting element configured to grip the selected holder and to lift the selected holder into the working plane.

3. The cutting station according to claim 2 , wherein the processing head for gripping one holder of the plurality of holders has at least one gripping piece and the holder has at least one driver element, wherein the gripping piece and the driver element engage each other for lifting the selected holder.

4. The cutting station according to claim 1 , wherein the processing head is designed to process the selected cable element while it is held in one holder of the plurality of holders.

5. The cutting station according to claim 1 , wherein the processing head comprises at least one pull-off unit for pulling the selected cable element in the longitudinal direction and a cutting unit for cutting off the cable element.

6. The cutting station according to claim 1 , wherein two pull-off units and a measuring element for measuring a taken-off length of the selected cable element are provided, the measuring element being arranged between the two pull-off units.

7. The cutting station according to claim 1 , wherein each holder of the plurality of holders has at a front end of the holder a nozzle for receiving a front end portion of the selected cable element.

8. The cutting station according to claim 7 , wherein the processing head has a print head and wherein the nozzle has a window providing a printing pattern for printing on the selected cable element.

9. The cutting station according to claim 1 , wherein the processing head has a receptacle for a nozzle arranged on each holder of the plurality of holders, through which the selected cable element is guided.

10. The cutting station according to claim 9 , wherein the processing head has at least one print head for printing on the respective cable element, which is positioned or can be positioned at the receptacle.

11. The cutting station according to claim 9 , wherein a cutting unit is arranged in the longitudinal direction downstream of the nozzle.

12. The cutting station according to claim 1 , wherein the receptacle comprises at least one centering element.

13. The cutting station according to claim 1 , wherein a gripping unit for the selected cable element is arranged in the longitudinal direction downstream of the processing head, wherein the gripping unit is designed to grip a front end of the selected cable element and to transfer a line section of the selected cable element to at least one transport gripper.

14. The cuffing station according to claim 13 , wherein the gripper unit is pivotable about a pivot axis and two transport grippers are provided for receiving two ends of the line section and the gripper unit is pivoted during operation in such a way that the line section of the selected cable element is held by the transport grippers, thereby forming a loop.

15. The cutting station according to claim 1 further comprising a transport system, which extends in front of the processing head in transverse direction and is designed to receive and to transport a cut-to-length line section.

16. The cutting station according to claim 14 , wherein the two transport grippers are part of the transport system and are moved in transverse direction during operation.

17. The cutting station according to claim 1 , wherein an untwisting unit is provided which has a fixed gripper and a rotary gripper rotatable about an axis of rotation, wherein in operation the rotary gripper is configured to rotate one of the two ends of a cut-to-length line section by a predetermined angle of rotation.

18. A method for automatically cutting a cable element to a specific length with the aid of a cutting station according claim 1 , the method comprising:
arranging a plurality of cable elements in a plurality of holders, the plurality of holders extending in a longitudinal direction and being arranged in a magazine plane side by side in a transverse direction; and
selecting and processing of a selected cable element from the plurality of cable elements from the magazine with the aid of a processing head,
wherein the processing head moves in the transverse direction relative to the magazine, grips, pulls off and cuts to length the selected cable element, and
wherein each holder of the plurality of holders holds one cable element of the plurality of cable elements with the aid of at least two fixing elements.
