Description

 Device for banding elongated objects

DESCRIPTION

The invention relates to a device for bandaging elongated objects according to the preamble of claim 1.

The field of application of the present invention lies primarily in the wrapping or bandaging of cable sets, in particular cable harnesses in the motor vehicle industry, as well as in trucks and other commercial vehicles and in the aerospace industry.

Bundling the cable sets makes it easier to install the cable harness in the end product. Further reasons for bandaging are the protection of the cables against mechanical stress (e.g. fraying), against dirt or against rattling noises. Depending on the requirements, various adhesive tapes, such as PVC tape, textile and fabric tape or fleece tape used.

The wrapping of the cables with adhesive tape is currently only carried out manually or semi-automatically. In the manual processing of the adhesive tape, the cable bundles are usually spanned on a laying board or a device. For bandaging, the adhesive tape is guided together with the roll of adhesive tape around the cable set and thus connected to form a cable harness. In the case of punctiform or only short line sections to be bandaged, the required pieces of adhesive tape are prepared, ie the required length of adhesive tape is pulled off, cut off, and only the adhesive tape section is wrapped around the line set. Machines such as those from ONDAL or DERFI are available on the market for semi-automatic bandaging. In these stationary machines, partial line sets are inserted into the taping machine by an operator. An adhesive tape roll is guided around the lines in the machine, so that the adhesive tape is placed around the partial line sets by these rotations. The rotation speed of the adhesive tape roll and the feed of the cable bundle are adjusted either manually or automatically.

European patent 0 219 739 describes a device for bundling or wrapping elongated things, in which the roll of adhesive tape is fixed in place. Instead, the object to be wrapped turns in the machine. A complicated system of deflection wheels ensures that the removed adhesive tape runs smoothly.

A disadvantage of these known machines is that their use is only possible with simple cable sets. A fully automatic bandaging of a main cable set, e.g. can contain up to 500 lines for a motor vehicle is not possible with the known machines.

The object of the present invention is to provide a device of the above. Provide a way with which even complex wiring harnesses can be bandaged fully automatically. Likewise, fully automatically assembled cable sets (1: 1 modules) should also be bandaged fully automatically.

The solution consists in a device with the features of claim 1.

With the device according to the invention it is possible to line sets that consist of a plurality of lines can bandage with a band over any distance with a freely selectable degree of coverage of the band fully automatically. This makes it possible, on the one hand, to tap automatic partial line sets, which are provided on both sides with fully automatic assembly machines with crimp contacts and are inserted in connector housings, fully automatically in the last necessary operation. This device is also capable of banding complex cable harnesses, such as those used for example in motor vehicles, directly after the manual laying of the cables on a laying board. The cable bundles are wrapped starting from the cable end inserted in a plug up to a branch. There the adhesive tape is automatically cut off and also automatically put back on the other side of the branch. This means that the entire line bundle can be bandaged successively. The compact design is an additional advantage because laying boards leave little space.

The use of the device according to the invention enables fully automatic bandaging with automatic cutting and attachment of the adhesive tape. Furthermore, different types of adhesive tape can be used with this device, and there is the possibility of freely selecting the degree of coverage of the adhesive tape. The taping data, such as the type of adhesive tape, degree of coverage, position of the attachment and cutting points and the taping length can be programmed. By using this device, high cost and quality advantages can be achieved.

Advantageous further developments result from the subclaims.

In the following an embodiment of this invention is described in more detail with reference to the accompanying drawings. Show it: Figure 1 is a schematic representation of the device according to the invention in its starting position;

Figure 2 shows the device attached to a robot arm according to Figure 1 with an inserted wiring harness;

Figure 3 is a schematic representation of the device according to the invention with a cable harness to be bandaged.

The device 1 according to the invention shown in FIGS. 1 and 2 essentially consists of a winding tool 2 with a fixed part 3 and a rotating part 4. A mechanical interface 5 is provided on one side of the winding tool 2, on which a robot arm shown only schematically is shown 6 can be provided. The outside diameter of the winding tool 2 is about 120 mm, the inside diameter about 50 mm.

The fixed part 3 essentially has two superimposed plates 10, 11 with a circular cross section. The plates 10, 11 are provided with a recess 12 which serves as a receptacle for the line bundle (40) to be wrapped, as can be seen from FIG. 2. On their outer circumference 10 ', 11', the plates 10, 11 do not lie one above the other, but form two legs 14, 15 of a bearing guide 13 into which the rotating part 4 is received in the form of a plain bearing 16 with a V-shaped cross section. On the plate 10, a cylinder 17 is provided in the exposed flat area facing the plate 11, which receives a locating pin 18 provided with bores 19. The plates 10, 11 are not completely congruent. The plate 11 has a recess 12 'which is slightly larger than the recess 12 of the plate 10 so that part of the flat area of the plate 10 is freely accessible.

The slide bearing 16 is V-shaped in cross-section with two flanks 16 ', 16 "and a base 20 in the bearing guide 13 so that the base 20 is freely accessible from the outside. Likewise, a flank 16' is at least partially exposed Purpose is the leg 15 of the plate 11 slightly shortened compared to the leg 14 of the plate 10.

The base 20 has a toothing 21 in which the toothing 23 of a toothed belt 22 engages. The toothed belt 22 runs over deflection rollers 24. A deflection roller is fastened to the interface 5 for the drive. This deflection roller also serves as a shaft for driving the toothed belt and is connected to an electric motor 25 which is provided on the side of the interface 5 opposite the deflection roller.

An adhesive tape roll 30 is in the middle of a holding device, not shown here, e.g. a pin or mandrel is rotatably attached to the flank 16 'of the plain bearing 16. The mandrel or pin is firmly seated on the slide bearing. The adhesive tape roll 30 or the like is around a sleeve. wound up, so that they can be put on the mandrel or pin and locked or otherwise fixed.

On the side of the adhesive tape roll 30 facing away from the winding tool 2, a cutting device 32 is fastened, which consists of an axis 33 and a cutting edge 34 provided with a bow spring 35.

The operation of the device according to the invention will now be described below. The robot arm with the open winding tool (FIG. 1) positions itself over the starting point of the cable harness section to be bandaged and moves into the cable harness from above (FIG. 2).

At the beginning of a bandaging process, the adhesive tape roll 30 is in the starting position at the vertically highest point (as shown in FIGS. 1 and 2), and the beginning of the adhesive tape sticks to the locating pin 18 (FIG. 2). The winding tool 2 is in this starting position in the open state, i.e. the fixed part 3 and the rotating part 4 of the winding tool 2 open the recess 12, so that a line bundle 40 can be approached from above. The winding tool then comprises the entire line bundle 40, as shown in Figure 2.

The rotating part 4 of the winding tool 2, driven by the toothed belt 22, moves with the adhesive tape roll 30 in a clockwise direction (arrow A in FIG. 2) around the cable bundle 40. The beginning of the tape is still fixed on the locating pin 18. Before the adhesive tape roll 30 has reached the starting position again after the first complete rotation through 360 °, the beginning of the tape is released from the locating pin 18. For this purpose, the mounting pin 18 is acted upon from the inside with compressed air, which penetrates through the bores 19 to the outside, so that the adhesive tape is partially or completely blown off from the mounting pin 18. In order to strip off any adhesive tape residues that may still be sticking, the locating pin 18 is drawn into the cylinder 17 and thereby performs a rotationally forced movement through 45 °. This ensures that the adhesive tape is detached from the locating pin 18.

After the locating pin 18 has been moved back into the winding tool 2 in the cylinder 17, the actual winding process can begin. The rotating part 4 of the Winding tool 2, on which the adhesive tape roll 30 is fixed, rotates clockwise around the cable bundle 40 and thereby bandages the cables with the adhesive tape. By coordinating the rotational movement of the rotating part 4 with the adhesive tape and the translational movement of the entire winding tool 2 with the aid of the robot arm 6, the degree of coverage of the adhesive tape can be determined. This process continues until the penultimate winding.

During the last rotation, namely in the second half, the locating pin 18 moves out of the cylinder 17 again. When the last rotation is completed by 360 °, the adhesive tape is again forced around the locating pin 18 and sticks to it. The rotating part 4 with the adhesive tape roll 30 rotates further into the starting position shown in FIG. 1. The adhesive tape now runs taut from the line bundle 40 over the locating pin 18 to the adhesive tape roll 30.

In the last step, the cutting device 32, driven by compressed air, now performs a very rapid rotation in the counterclockwise direction (arrow B in FIG. 2) and cuts the adhesive tape directly under the locating pin 18. The bow spring 35 attached to the cutting edge 34 of the cutting device 32 presses it remainder of the tape coming from the wire bundle 40 to the wire bundle 40. The second end of the tape sticks in the mounting bolt 18 and is additionally held on the bolt by negative pressure. The entire winding tool 2 moves vertically upward and releases the bandaged cable bundle 40. The winding tool 2 is ready for the next taping process, moves to the next starting position and the entire process begins again.

A reverse orientation of the rotary movement is naturally also conceivable, that is to say the rotation of the rotating part 4 counterclockwise and the movement of the

Cutter 32 clockwise. It is only necessary to ensure that the cutting edge 34 of the cutting device 32 does not hit the adhesive side of the adhesive tape and that the adhesive tape is wound accordingly onto the sleeve of the magazine.

When the tape roll 30 is completely processed, a tape roll change takes place at a change station. A pre-magazine station is also conceivable, on which the length of adhesive tape required for the next tape application is wound onto an adhesive tape change mandrel. Although this increases the number of changes, the end of the tape is always in a designated place.

By taking into account the required length of adhesive tape during a winding process, it is achieved that the tapes e.g. of a cable harness is exactly the length of adhesive tape required, and thus breaking off of the adhesive tape in the middle of a cable harness is avoided. In this way it is ensured that no manual intervention is required in the winding process and the entire winding process can thus be carried out fully automatically.

Compared to the prior art, the device 1 according to the invention thus represents a simple, compact, movable device which can be moved along the line bundle 40 to be bandaged, the individual bandaging steps and movements along the line bundle 40 being programmable. This makes it possible to easily tape complex cable harnesses, as shown in FIG. 3 using a simplified example.
