Abstract

The disclosure relates to an apparatus (10) for removing, at least in sections, at least one constituent part (6, 7) of a cable arrangement (1), comprising: —a positioning unit (11) having an insertion region (12), into which an end region of a cable arrangement (1) can be inserted; —an air stream supply device (64), which is designed to direct an air stream onto the cable arrangement (1); and—a processing unit (16), which can be displaced relative to the positioning unit (11); wherein a cutting region (50) is provided at at least one of the processing unit (16) and the positioning unit (11); and wherein the cutting region (50) is arranged in such a way that, in the context of the relative displacement, a predetermined constituent part (6, 7) of the cable arrangement (1) can be brought into contact with the cutting region (50) in order to separate, at least in sections, said constituent part (6, 7) from the cable arrangement (1). The disclosure further relates to a method for removing, at least in sections, at least one constituent part (6, 7) of a cable arrangement (1).

First claim

The invention claimed is:

1. An apparatus for removing, at least in a portion, at least one constituent part of a cable arrangement, comprising:
a positioning unit having an insertion region into which an end region of a cable arrangement can be inserted;
an air stream supply device, which is configured to direct an air stream at the cable arrangement; and
a processing unit, which is displaceable relative to the positioning unit;
wherein a cutting region is provided on at least one of the processing unit and the positioning unit; and
wherein the cutting region is so arranged that, within the scope of the relative displacement, a predetermined constituent part of the cable arrangement can be brought into contact with the cutting region in order to separate that constituent part at least in a portion from the cable arrangement, wherein at least one of the processing unit and the positioning unit comprises a clamping unit which is configured to clamp the constituent part to be removed at least in a portion according to the relative displacement, wherein the respective other of the processing unit and the positioning unit comprises a counter-clamping region, wherein, within the scope of the relative displacement, the constituent parts to be removed can be clamped between the clamping unit and the counter-clamping region before the cutting region separates the constituent part to be removed from the cable arrangement.

2. The apparatus as claimed in claim 1 ,
wherein the constituent parts to be removed comprise at least one of a nonwoven material or a filler material.

3. The apparatus as claimed in claim 1 ,
wherein the air stream of the air stream supply device flows at an angle of less than 90° relative to and/or substantially along a longitudinal axis of the cable arrangement, and in particular wherein the air stream is directed at least partially contrary to an insertion direction of the cable arrangement into the insertion region.

4. The apparatus as claimed in claim 1 , wherein the processing unit comprises a receiving portion in which the end region of the cable arrangement can be received at least in a portion.

5. The apparatus as claimed in claim 4 ,
wherein the receiving portion is configured to limit an insertion length of the end region of the cable arrangement.

6. The apparatus as claimed in claim 1 , wherein the cutting region is provided on one of the processing unit and the positioning unit, and on the respective other of the processing unit and the positioning unit there is provided a support region on which the cutting region can be supported within the scope of the relative displacement.

7. The apparatus as claimed in claim 6 ,
wherein an interference fit is provided between the cutting region and the support region.

8. The apparatus as claimed in claim 1 , wherein the clamping unit is displaceably received within the corresponding unit from the processing unit and the positioning unit.

9. The apparatus as claimed in claim 8 ,
wherein the clamping unit is supported via a return device on the corresponding unit from the processing unit and the positioning unit, in particular wherein the return device is resiliently deformable at the latest after the clamping contact has been established and with continuation of the relative displacement of the processing unit and the positioning unit.

10. The apparatus as claimed in claim 1 , wherein the apparatus further comprises a sensor arrangement which is adapted to detect at least one of the following:
a diameter of the cable arrangement present in a predetermined region of the apparatus and/or a change in diameter of the cable arrangement which occurs in that region during the insertion; and
a change in the air stream and/or changing pressure conditions within the apparatus.

11. The apparatus as claimed in claim 10 , wherein the apparatus further comprises a control unit which is configured
to change an operating state of the air stream supply device according to a detection signal of the sensor arrangement; and/or
to control the relative displacement between the processing unit and the positioning unit according to a detection signal of the sensor arrangement.

12. The apparatus as claimed in claim 1 , wherein the apparatus is configured to generate a negative pressure for extracting the separated constituent parts by suction, at the latest after the constituent parts to be removed have been separated at least in a portion.

13. A method for removing, at least in a portion, at least one constituent part of a cable arrangement, comprising the steps:
inserting an end region of a cable arrangement into an insertion region of a positioning unit;
generating an air stream directed at the cable arrangement;
moving a processing unit relative to the positioning unit in such a manner that a cutting region provided on at least one of the processing unit and the positioning unit contacts the constituent part to be removed and separates it from the cable arrangement,
wherein the method is carried out by means of an apparatus as claimed in claim 1 .
