An independent claim is also included for the following: (a) a method of using the inventive arrangement.

Description

The invention relates to a device according to the preamble of the preamble of claim 1.

Cable sets in flat conductor technology are increasingly being used in all areas of vehicles and devices. For assembling these lines, it is often necessary to partially tape certain areas. Thus, one or more desired properties is achieved at the corresponding points of the line. The prior art is that this tape is manually applied by hand.

A device forming the genus is known from EP0219739A1, with which only elongated objects in a round shape can be bundled or enveloped or marked.

The invention is therefore based on the object to provide a device or a method that goes beyond bundling (wrapping, marking) of objects in a round shape or, with an adhesive tape bundling or wrapping or marking objects with a in the essential rectangular cross-section - such as flat cables - automatically performs.

This object is achieved according to the characterizing part of claim 1 or according to the characterizing part of claim 5. Further embodiments of the invention will become apparent from the dependent claims.

By arranging an upper pressure roller and a lower axis-parallel pressure roller which correspond to a carriage, for example, a more than 360 degree wrap (for example of up to 450 degrees) of the adhesive tape is possible.

The device is provided with a programming device for specifying a tape leader length, for specifying a width of a flat conductor to be processed, for specifying a cutting time and a carriage stroke, and for specifying a corresponding sequence of a third drive for the tape dispenser, a second drive for the carriage, and a first drive for the lower pressure roller, wherein the programming device operates either in the "repetition" mode or in the "sequence" mode.

By driving the lower pressure roller and its change in direction of rotation is ensured at right angles to the flat conductor longitudinal axis and wrinkle-free ironing of the adhesive tape on the underside of the flat conductor.

By synchronizing tape dispensers and ironing the adhesive tape, a wrinkle-free ironing of the adhesive tape running at right angles to the flat conductor longitudinal axis is ensured on the upper side of the flat conductor.

For example, by resilient adaptation of a gap between the two pressure rollers differently high flat conductor or rectangular objects can be wrapped or bundled or marked.

Fig. 1 shows in a side view an embodiment of a device 20 for automatically bundling or wrapping (wrapping 36) or marking objects 30 having a substantially rectangular cross-section, such as flat conductor 30.1,30.2,30.3, with several in a plane parallel to each other arranged cores or foil conductors by means of an adhesive tape 31, which can be carried out, for example, a marking, isolating, protecting, fixing, molding and grouping. The device 20 is provided with a tape dispensing device 1 with a cutting device 25 (upper blade 4, lower blade 5) for the adhesive tape 31 of an adhesive tape roll 11. The device 20 comprises slide 2.2.1, a compression spring 3, a first (pneumatic) drive 8 for a lower pressure roller 7, a second (pneumatic) drive 10 for the slide 2.2.1 and a third (pneumatic) drive 12 for the tape dispenser 1 as well as one Bandumlenkhilfe a tuyere 9. A reversal of the direction of rotation of the lower pressure roller 7 together with the blow bar 9 causes a bending of the adhesive tape 31. In most cases, a bending of the adhesive tape 31 can be achieved solely by reversing the direction of rotation of the lower pressure roller 7. To handle all types of adhesive tape (flexibility, strength, etc.), the Blasdüsenleiste 9 is advantageous.

FIG. 2 shows a front view of the device 20 according to FIG. Two juxtaposed metal jaws 13,13.1 are pneumatically moved downwards by means of a pneumatic cylinder 14 (FIG. 5) for fixing the flat conductor 30.1 (FIG. 8) to the carriage 2,2,1, wherein below the clamping jaws 13,13.1 an elastic layer 26 and below a hard plastic part 27 are arranged. As a result, an elastic fixing of the flat conductor 30.1 with the hard plastic part 27 is achieved. For pneumatic operation, the device 20 is connected via a line 18 to a control device 35 (FIG. 6).

FIG. 3 shows a side view of the front part of the device 20 with an upper pressure roller 6 raised by means of a swivel joint 16. By fitting a gap Y between the upper and lower pressure rollers 6, 7 by means of a compression spring 3, differently shaped flat conductors 30 , 30.2, 30.3 or rectangular objects 30 are wrapped or bundled or marked.

4 shows a side view of the front part of the device 20 with a lowered upper pressure roller 6.

Fig. 5 shows in a partial side view of the device 20 with clamping jaws 13,13.1, which are moved by a controllable pneumatic cylinder 14 via a guide 15 from an open to a lowered position. The clamping jaws 13,13.1 serve to hold objects to be bandaged or wrapped 30 or flat conductors 30.1, 30.2, 30.3.

6 shows a programmable control device 35 with a touchscreen 19 (display), a compressed-air accumulator 23 (shown in dashed lines), which is connected to a compressed-air line 18 of a compressed-air generator, not shown, a power supply 21 and a foot switch 22. On the touch screen 19, a specific program example is shown. The control device 35 of the device 20 is used to specify a strip length λ, to specify a width B of a processed flat conductor 30.1, to specify a cutting time and a carriage stroke, and to specify a corresponding sequence of a third drive 12 for the tape dispenser 1, a second drive 10 for the carriage 2.2.1 and a first drive 8 for the lower pressure roller 7, wherein the control device 35 either in the mode "repetition" (the same lead 30.1 is wrapped in different locations, for example, always step 3) or in the mode "sequence" ( a number of different flat conductors 30.1 are wrapped one behind the other, for example, always steps 1 to 4) works.

7: The corresponding sheath 36 on a flat conductor 30.1 comes about in that the flat conductor 30.1 is first fixed with two clamping jaws 13,13.1, right and left at the point to be wrapped on a slide 2,2.1.

Fig. 8: Now depending on the type of wrapping or depending on the respective width B and height H of the flat conductor 30.1 the adhesive tape 31 vorgespendet in the manner with a Bandvorspendelänge X that with a lower, first end 32 in front of the two axially parallel to each other Pressure rollers 6,7 hangs.

9: If now the carriage 2 is moved with the clamped flat conductor 30.1 into the device 1, the flat conductor 30.1 first strikes the adhesive tape 31 hanging in front of the pressure rollers 6,7.

Fig. 10: If the carriage 2 now moves between the two pressure rollers 6.7, the adhesive tape 31 is pressed or ironed on both long sides of the flat conductor 30.1.

FIG. 11: If a complete envelope 36 of the flat conductor 30.1 is desired, the adhesive tape 31 is cut to length in such a way that after passing through the pressure rollers 6,7, a second end 34 of the adhesive tape 31 projects beyond the flat conductor 30.1.

12 to 14: By an air flow 24 of a Blasdüsenleiste 9 (Figure 12), coupled with a reversal of the lower pressure roller 7, the protruding second end 34 of the adhesive tape 31 is moved in such a way (FIG is again pressed by the pressure rollers 6.7 in the opposite direction to the bottom 33 of the flat conductor 30.1 pressed or ironed (Fig. 14).

One or more flat conductors 30.1 are moved together with an adhesive tape 31 by adjusting in the height of the cross-section pressure rollers 6.7.

By appropriate provision of the adhesive tape 31 and changing the three drives 8, 10, 12 coordinated with one another, different cross-sections of flat conductors 30. 1 can be provided with a sheath 36.

By appropriate provision of the adhesive tape 31 before and after the pressure rollers 6, 7, different types of sheaths 36 can be produced around flat conductors 30. 1 (FIGS. 17 to 33).

The enclosure 36 may be partially - with a gap - or overlapping.

By means of the device 20, by simply overlapping the adhesive tape 31, a branch can be produced on the cross section to be enveloped on one side in order to produce a folded fixing therewith, for example (FIGS. 29 to 32).

By a synchronization of tape dispensing and ironing the adhesive tape 31, a wrinkle-free and at right angles to the longitudinal axis of the cross-section to be enveloped ironing of the adhesive tape 31 is ensured.

The device 20 allows processing of continuous single-sided adhesive tape 31.

Fig. 15 shows the device 20 in a perspective view obliquely from the front. To guide an elongate object 30, the device 20 is in the region of the slide 2.2.1, each with a leading edge 28 of a Guide rod 29 provided. The device 20 is provided with a housing which is provided with a handle 17 for opening.

FIG. 15a shows the device 20 according to FIG. 15, but with an object 30 (flat conductor 30.1, 30.2, 30.3), which is already provided with a wrapping 36 or wrapping or marking.
