Description

Processing unit for processing at least one wire bundle composed of a plurality of individual wires

Technical Field

The invention relates to a processing unit for processing at least one wire bundle composed of a plurality of individual wires into a bound wire bundle or cable bundle, and to a method for binding and/or coating a wire bundle or wire bundle composed of a plurality of individual wires (11), in particular a cable bundle, using the processing unit.

Background

Numerous devices for binding or applying adhesive to wire bundles are known from the prior art. The wire harness is typically held by two fixtures at the ends of the wire harness. The bundle of wires tensioned between the two fixtures is then bound. However, stretching wire bundles is very laborious and time consuming. Furthermore, this process cannot be easily automated.

Disclosure of Invention

It is therefore an object of the present invention to provide a processing unit and a method for binding and/or wrapping a wire set or bundle of wires consisting of a plurality of individual wires, which enable automatic binding of the wire bundle in a non-tensioned state.

This object is achieved by a combination of features according to claim 1.

According to the invention, a processing unit is proposed for processing at least one wire bundle consisting of a plurality of individual wires into a lashed or lashed and fixed cable bundle wire or cable bundle by means of a suitable material, said processing unit comprising: a bundling device designed for bundling the wires, which combines the individual wires into a wire bundle in a relevant intermediate zone in an operation from a starting position to an intermediate or ending position; means for compacting the bundled wires; and a binding device for binding the wire harness by winding with a binding element. The binding element is in particular a bandage, a tape, an adhesive tape, a strap or other material suitable for binding wires, such as a cable tie.

This has the advantage that the wire bundle does not have to be stretched for binding due to the processing unit. Furthermore, this enables automatic production of individual wire bundles outside the raceway. This provides a potentially higher level of automation throughout the process and can be linked to other automated production steps.

In an advantageous embodiment variant, the ligating means are designed as funnel-shaped or cone-shaped. This is particularly advantageous for bundling wires.

Preferably, the handling unit is designed such that the strapping device comprises two clamping arms, which are funnel-shaped or cone-shaped. Thus, the strapping device can be adapted and adjusted to the corresponding wire harness diameter. Furthermore, the respective separate binding device can be better contacted on the electric wire.

In one embodiment of the invention, the device for pressing comprises at least one forming roller. The at least one forming roller is in particular a roller with a concave profile, more in particular a roller made of rubber, or a roller made of flexible material applicable to the bundle of wires, in particular an air-filled roller. Advantageously, the means for compacting can exert pressure on the wire by means of adjustable or adjustable forming rollers and create the necessary friction on the wire in order to continuously tension the wire during the treatment.

The invention also provides a method for binding and/or covering a wire set or a wire bundle, in particular a cable bundle, consisting of a plurality of individual wires with a processing unit according to the above-disclosed publication, the method comprising first guiding a binding device in a processing direction along the individual wires from a starting position to an intermediate or final position for binding the wires into the wire bundle. The compression of the bundled wire bundle or wire set is then carried out by means of a device for compacting.

Wherein the processing unit tensions the wire set in a predetermined manner due to guiding in the processing direction at least during pressing and/or bundling. And then bound by means of the binding means of the processing unit, in particular during the pressing and binding of the wire bundle and/or in the state of the wire bundle being pressed and bound.

In this way, an automated method is achieved in which, thanks to the processing unit, the wire bundle does not have to be stretched for binding. Furthermore, this enables automatic production of individual wire bundles outside the raceway. This provides a potentially higher level of automation throughout the process and can be linked to other automated production steps.

In a preferred embodiment of the method, the individual wires are held on the fixed part, in particular on one side. In an advantageous variant, the invention provides that the electrical line is held immediately behind the plug housing of the electrical line group or at a node of the electrical line group. Advantageously, the wires do not have to be clamped at two fixing points and the possibility of automating the method outside the cable tray can be achieved.

It is further advantageous if the wires are oriented vertically, in particular in a suspended manner, such that the treatment direction is directed substantially vertically downwards when guided. In this way, bundling of the wires is made easier by means of gravity.

Furthermore, in an advantageous embodiment, the processing unit contacts the wire in the processing direction, in particular immediately after the fixed part of the wire, upon contact. In this way, the contact of the processing unit with the wires is optimized.

In a further advantageous variant, the invention unsubscribes from guiding the processing unit continuously along the wire.

In an advantageous embodiment variant, the two clamping arms are moved to the open position before contact and to the closed position after contact. The distance between the two clamping arms in the closed position is determined according to a predetermined diameter of the wire set. This has the advantage that the strapping device can be adapted and adjusted to the respective wire bundle diameter. Furthermore, the respective separate binding device can be better contacted on the electric wire.

Preferably, the method is performed in such a way that: during the extrusion, the at least one forming roller is guided along the bundled wire set and thereby extruded in a predetermined manner. Furthermore, the at least one forming roller may be movable. The at least one forming roller creates friction on the wire set so that the wire or wire set is held in tension during the method.

In an exemplary embodiment of the method, provision is made for the banding device to spread the banding element circumferentially around the wire set during banding. Wherein the banding device performs the cladding/banding in a spiral shape due to the movement of the process unit in the process direction.

In an additional or alternative embodiment of the method, the banding device spreads the Tape (Spot Tape) during banding. Wherein the ligating means encases/ligates the various locations spaced apart from one another. Tape means a banding element which is arranged correspondingly in a single position.

In a preferred embodiment variant of the method, the processing unit is arranged on the operating unit and, when contacted and guided, is moved and/or positioned and/or guided by the operating unit. The operating unit here also means in particular a robot, a robotic arm or a processing machine in which further processing steps for producing the wire group or the wire bundle or the cable bundle are carried out. This optimizes the automation of the method.

The features disclosed above may be combined in any way as long as this is technically feasible and they are not mutually contradictory.

Detailed Description

The drawings are exemplary schematic diagrams. Like reference numerals in the drawings denote like functional and/or structural features.

In fig. 1, a processing unit 1 is shown for processing at least one wire bundle 10 consisting of a plurality of individual wires 11 into a bundled wire or cable set, the processing unit comprising: a bundling device 2 designed for bundling wires 11, which in operation from a starting position to an intermediate or end position combines the individual wires 11 into a wire bundle 10 in a relevant intermediate area; means 3 for compacting the bundled wires 11; and a binding device 4 for binding the wire harness 10 by winding with the binding element 41. Depending on the application, the binding element is a bandage, tape, adhesive tape, band or other material suitable for binding the wires 11, such as a cable tie. The wires 11 are vertically suspended oriented such that the treatment direction is directed substantially vertically downwards when guided. Further, the electric wires 11 are each held at one side at the fixing portion 111, and are held immediately after the plug housing of the electric wire group 10.

Fig. 2a and 2b show a strapping device 2 of the processing unit 1 shown in fig. 1, fig. 2a shows a front view of the strapping device, and fig. 2b shows a cross-sectional view of the strapping device. The strapping device 2 comprises two clamping arms 21 extending in a funnel shape or a cone shape. The clamping arms 21 may be splayed or polymerized according to the diameter of the bundle 10 of wires, indicated by the respective arrows.

Fig. 3a and 3b show the device 3 of the processing unit 1 shown in fig. 1 for compacting a bundle of wires 11. Fig. 3a shows a perspective view of the device 3 for compacting a bundle of wires 11, and fig. 3b shows a front view of the device 3 for compacting a bundle of wires 11. The means 3 for compacting comprise four forming rollers 31. The corresponding forming roller 31 is a roller with a concave profile, which is made in particular of rubber, or an inflatable roller made of flexible material that can be adapted to the bundle of wires. Furthermore, the forming roller 31 of the device 3 for compacting can be moved according to the arrow shown.

The processing unit 1 shown in the above-mentioned figures is designed to perform a method for binding and/or wrapping a wire set or wire bundle 10 consisting of a plurality of individual wires 11, said method comprising first guiding the binding device 2 along the individual wires 11 in a processing direction 8 (indicated by the respective arrow in fig. 1) from its actual position to a middle or end position for binding the wires 11 into the wire bundle 10. The two clamping arms 21 are moved to the open position before contact and to the closed position after contact. The distance between the two clamping arms 21 in the closed position is determined according to the predetermined diameter of the electric wire set 10. The bundled wire harness 10 or wire set is then compressed by means of the device 3 for compacting. The processing unit 1 tightens the wire groups 10 in a predetermined manner based on the guidance in the processing direction at least at the time of pressing and/or bundling. At the time of extrusion, the four forming rollers 31 are guided along the bundled wire set 10 and thereby pressed in a predetermined manner. The forming roller 31 is movable and creates friction on the wire set 10 so that the wire set 10 remains tensioned during this process. And then bound by means of the binding device 4 of the processing unit 1, in particular during the pressing and binding of the wire bundle 10 and/or in a state in which the wire bundle 10 is pressed and bound. During the binding, the binding device 4 spreads the adhesive tape circumferentially around the electric wire set 10, wherein the binding device 4 wraps/binds in a spiral shape due to the movement of the processing unit 1 in the processing direction. Alternatively, the banding device 4 spreads the tape during banding, wherein the banding device 4 wraps/bands various positions spaced apart from each other.

In this method, when the processing unit 1 contacts the electric wire 11, the processing unit 1 contacts immediately behind the fixing portion 111 of the electric wire 11 in the processing direction. The processing unit 1 is continuously guided along the electric wire 11.

In addition, the processing unit 1 is arranged on the operation unit 7, and upon contact and guidance, the processing unit 1 is moved and/or positioned and/or guided by the operation unit 7.

The practice of the invention is not limited to the preferred exemplary embodiments given above. Instead, many variants are conceivable, which utilize the proposed solution even in radically different designs.
