In the embodiment described below the cable receiving surface to form a Kabelaufnahmeund Stretching range 15 by an upper Mitnahmetrum an endlessly circulating receiving conveyor 14 formed. For shorter cables 3,4, however, would be a stationary Cable receiving surface are sufficient.

As can be seen in particular from FIG. 1, the cable depositing device is 1 with a conventional, previously known Cable processing machine 2 to a common Work unit connected, and used for separated storage of processed by the wire processing machine 2 Cables 3 and 4 for the production of so-called Double crimp cables 25 or e.g. from two individual leaders of different diameters.

The two cables 3 and 4 are in a known manner means the two tape drive units 5 and 6 a Pivoting head 7 fed, which the front ends of the Cable 3 and 4 for their stripping and then Aufpressung a crimp contact one or more of the Processing stations 8 to 11 supplies.

After this processing the front ends of the two Cables 3 and 4 will do this at high speed along the two ejection axes of motion 12 and 13 in FIG the cable tray device 1 ejected.

In the area of the two ejection movement axes 12, 13 of the both conveyed out of the wire processing machine 2 Cable 3,4 is through an upper Mitnahmetrum an endlessly circulating receiving conveyor belt 14 a Cable receiving and stretching area 15 formed. It will the receiving conveyor belt 14 via the two pulleys 16 and 17 (Fig.2) out, and by means of a with the Guide roller 17 connected drive motor 18 driven in such a way that the rotational speed of the receiving conveyor belt 14 is greater than the ejection speed the two from the cable processing machine 2 3 and 4 out to a stretched out Recording of the latter two on the recording and Stretching range 15 to achieve.

In the cable entry area of the receiving conveyor belt 14th is one to seize the in their transport direction seen the rear ends of the two cables 3 and 4 certain, provided with two cable gripping units 19 and 20 Swivel arm 21 for feeding the rear ends of Both cables 3 and 4 to a swung in the Swing arm 21 located Abisoliereinheit 42, then to a cable end mating unit 43, and then to a double crimping unit 22, provided. The Kabelendenzusammenführeinheit 43 can thereby as in the European patent application EP-A-0 984 530 be. In the cable end merge unit 43, the previously stripped rear cable ends of the two cables 3 and 4 combined and then in a double crimping unit 22 by means of a common crimp contact connected with each other.

The provided with two Kabelergreifungseinheiten 19 and 20 Swivel arm 21 can be part of the cable processing machine 2 or part of the cable storage device 1 represent.

It serves in a known manner, a first motor Drive 47 for precisely controlled pivoting of Swivel arm 21 and a second motor drive 46 for longitudinal displacement of the latter (Figure 8).

As can be seen from Figures 2 to 7, are in the Kabelendenzusammenführeinheit 43 associated pivot position the pivoting arm 21 (dashed in Figure 1) drawn) below the two with the latter connected Kabelergreifungseinheiten 19 and 20 a the both merged by the cable end assembly unit 43 rear ends of the two cables 3 and 4 in this deflected pivot position of the pivot arm 21st into the detection range of the cable gripping unit 20 liftable (Figure 3) and after their capture by the latter releasing (Figure 4), with a pivotable Kabelabstützbügel 23 provided Kabelabstützanordnung, and one via the cable gripping unit 20 connected to the pivot arm 21, before merging the two through the Kabelendenzusammenführeinheit 43 to be interconnected cables 3 and 4 in the vertical direction between the two latter swing-down separating flap 24, provided.

This Separierklappe 24 is after completion of the Doppelcrimpkabels 25 for further separation of the two crimped together cables 3 and 4 of the latter in vertically downwardly pivoted Separierposition (Figure 4) leave, and by appropriate pivoting back the swing arm 21 in a pivot position the latter moves, in which the Separierklappe 24 just above one in one below located first cable tray 26, after upwardly extending first cable guide and Separator 28 is located. In this pivot position of Swing arm 21 is the Separierklappe 24 by extension the cable guide and -Separierteiles 28 in releasable Intervention with the one in this pivot position the swing arm 21 below the two with the Swivel arm 21 connected Kabelergreifungseinheiten itself located, parallel to the longitudinal direction of the receiving conveyor belt 14 extending and perpendicular to this longitudinal direction in a below the same in one in the longitudinal direction C movable second cable tray 27 emptied by lateral pivoting first Cable tray 26 of extending first cable guide and -Separierteil 28 brought.

This first, along with the first cable tray 26 pivotable cable guide and -Separierteil 28 is to maintain the separation of the two cables 3 and 4 of a double crimping cable 25 during its transfer from the first cable tray 26 into the second cable tray 27 in emptying the first cable tray 26 (Figure 7) releasably engaged with one in the second Cable tray 27 arranged second double crimp cable cable guide and -Separierteil 29 brought.

When using thin, very flexible cables 3 and 4 It may be possible that this when swinging the Swivel arm 21 from a parallel to the receiving conveyor belt 14 extending basic position easily sag. To safely avoid these cables 3, 4 in such a case on the first cable guide and Separate part 28 could get stuck is the latter slidable in its longitudinal direction, i. during the Swiveling the pivot arm 21 in the illustrated in Figure 2 Position retractable, and later engaged with the Separierklappe 24 moved out (Fig. 5).

To a proper transfer of the first in the cable tray 26 located Doppelcrimpkabel 25 in the second cable tray 26 even at smaller swivel angles the first cable tray 26 in the emptying position (Fig. 7) of the same is the first Cable guiding and separating part 28 in his Longitudinal along the same sliding cable slide 30 assigned.

To see in the direction of passage, the rear ends of the both to a double crimp 25 to be connected cable 3, 4 in engagement or out of engagement with the cable processing stations 42, 43 and 22 are to bring the two cable gripping units attached to the swivel arm 21 19 and 20, with the help of a swivel arm 21 in its longitudinal direction shifting motor drive 46 controlled by the control unit 33 (FIG. 1), precisely displaceable.

Furthermore, the two cable gripping units 19 and 20 each have a vertical axis 38 and 39 in a horizontal plane pivotally attached to the pivot arm 21, and over two pneumatic cylinder units 32 and 33, each with three Working positions of the other cable gripping unit pivotable so that e.g. at the Crimping the rear merged ends of the Cable 3 and 4 in the double crimping unit 22, the cable gripping unit 19 for better accessibility two to be machined rear ends of the cables 3 and 4 laterally pivoted away with the aid of the pneumatic cylinder unit 33 can be.

In addition, the two cable gripping units 19 and 20 thanks to the two vertical guides 40 and 41 opposite the effect of at least one upward-acting one Compression spring (not shown) spring down lowered. This is especially true when crimping in the Doppelcrimpeinheit 22 important because when crimping using a press ram the respective cable ends of the two Cables 3 and 4 are lowered a little, and while the associated Kabelergreifungseinheit 20 via the punch by the same amount against the Spring action is lowered down.

The cable end mating unit 43 is, as already mentioned, e.g. as in European Patent Application EP-A-0 984 530 described, formed, i. the two to be crimped together, stripped ends of the both cables 3 and 4, as in particular from the FIGS. 2 and 3, one gripper unit 44 each, or 45 of the cable end assembly unit 43, then these two ends after release of the two cables 3 and 4 through the two cable gripping units 19th and 20 by applying a rotational movement of the gripper unit 44 associated gripper merged (Fig.4), the two cables 3 and 4 together by the Cable gripping unit 20 held, and then this two such merged ends after another Deflection of the pivot arm 21 to the double crimping unit 22 in the latter via a single crimp contact connected with each other.

Thereafter, the pivot arm 21 is swung back again, i.e. in the Kabelabwurfposition shown in Figure 5 where the first cable guiding and separating part 28 brought into engagement with the Separierklappe 24, and then the gripper of the cable gripping unit 20 is solved, so that the double crimping cable 25, as out of Figure 6 can be seen, with the cables 3 and 4 through the first cable guiding and separating part 28 separated, falls down into the first cable tray 26.

The arrangement and the pivot drive of the separating flap 24 is in particular on a larger scale from the figures 9, 10 and 11 can be seen.

As can be seen from these figures, the pivotable Kabelseparierklappe 24 and the drive 34 at the Kabelergreifungseinheit 20 flanged. For pivoting the Separierklappe 24 is the pneumatic drive 34th provided with a rotary piston 35, which as in particular 11, pneumatically by about 90 ° between the side stop surfaces of a fixed Stop element 36 within a cylinder 37th can be moved.

Of course it is also possible, only one cable gripping unit 20 provide and the two cables. 3 and 4 in two steps of the cable end merge unit 43 feed.

In operation of this Kabalablagevorrichtung 1 is first a certain batch size of finished double crimp cables 25 stored in the first cable tray 26 and after reaching this lot size while maintaining the separation of the cables 3 and 4 in the second cable tray 27 passed, which thereafter in their longitudinal direction C is moved and thus the finished double crimping cable 25 for their setting and removal by hand out of the danger zone of the cable processing machine 2 moved out.

After emptying the first storage tray 26 this can immediately be moved back to their shooting position, so that the preparation of the double crimp 25 can go on continuously, and to the safe Removal of the finished batch sizes on double crimp cables 25 by hand from the second cable tray 24 anyway enough time remains.
