Apparatus and method for coiling cable or wire pieces to give a coil having two further processable ends
Description
The invention relates to an apparatus and method for coiling cable or wire pieces to give a coil having two further processable ends.
Apparatus and methods for coiling cable or wire pieces to give a coil having two further processable ends are known. After a process for cutting cable or wire to length, they serve as a rule for producing an intermediate product, namely a coil, which is easier to transport and to store temporarily, in contrast to a loose cable or wire having a certain length. In particular, the invention is concerned with the coil as an intermediate product whose two ends (beginning and end of the cable or wire piece) are to be further processed after the production of the coil.
Various apparatuses are known for the purpose of removing a coil from its coiler. An obvious apparatus comprises the relaxation of a coil former in order to be able to remove the coil more easily after coiling. A coil former is relaxed and is rotated into a coil removal position (EP1387449A) . At the same time, this apparatus comprises two carriages which are displaceable along linear guides and have clamping apparatuses for the cable ends of a cable coil. With the aid of the carriages, the cable ends can be positioned relative to the coil or relative to the apparatus .
DE425975A describes a winder (= coil former) for coiling elongated objects, the diameter of the winder being variable and elastic. Such a winder has not been mentioned for the coiling of wires and cables. Such a design would not be suitable for an apparatus which is intended to bring the cable or wire ends to a particular, exactly defined position which is suitable for subsequent further processing.
DE3439628C specifies an apparatus in which the diameter of a winder can be changed for winding and unwinding of coils having different coil diameters. In the case of this apparatus, too, the ends of the cable or wire are not specially positioned by the apparatus itself.
The prior art is furthermore acquainted with apparatuses in which the leading end of a cable is held by a clamping apparatus on the coiler and accordingly can be spatially positioned. Coilers are also known in which the trailing end of the cable is gripped by a separate clamping apparatus so that both the leading and the trailing cable end can be spatially positioned in order, for example, to permit transfer of these ends to a further processing apparatus.
In these and other known apparatuses for coiling, it is furthermore envisaged to fix the coil in its spatial structure in such a way that a binder encompasses the coil - i.e. the wound layers of the cable or wire - with a suitable material so that the individual layers or windings cannot become detached from one another. Binders having adhesive tapes or binders having wires
or wire-supported tapes are available for this purpose.
However, all these known apparatuses cannot eliminate one deficiency: depending on the individual cable or wire length from the prior process for cutting to length, when the ends of the cable or wire are held firmly the coil will be more or less loosely wound or the last winding of the cable or wire may not rest tightly on the coil but form a lateral bulge in the form of a cable or wire loop to one side or will hang down loosely from the coil.
This complicates the further processing of the cable ends since this loop may become entangled with components of the further processing apparatuses and/or of the coiler. If in addition the coil is to be temporarily stored as an intermediate product without the two ends of the coil being continuously held, the ends may be at different distances from the coil, which complicates the automatic gripping of these ends.
It is therefore the object of the invention to develop a coiler and a coiling method in which the two free ends of the cable or wire automatically come to rest at predefined locations even without particular holding measures, or to design the coiler in such a way that the trailing end of the cable or wire comes to rest at the same distance from the geometrical centre of the coil as the leading end, independently of the cable or wire length, and in addition the leading and trailing ends are in an identical plane and are parallel to one another .
This positioning of the cable ends enables both ends to be accepted in a defined manner from, for example, clamping or holding apparatuses in order thus to permit the further processing of the ends. The cable or the wire should maintain the same predefined and desired tension everywhere in the coil. In particular, there should be no regions of the coil where the coiled cable or the cabled wire has an undefined position.
In the coiling process, the coiling axis of the coiler should not need to be moved relative to the clamping and holding apparatuses, in order to ensure a low level of complexity of construction.
This object is achieved by the use of the software- apparatus features of claims 1 and the method features of claim 8. Further developments of the invention and variants thereof are stated in the dependent subclaims.
A coiler according to the invention comprises a coil former adjustable in diameter under motor power and a rotary drive for the coil former and a computer control which comprises software which, in the operating state and with a knowledge of the cable or wire geometry and cable or wire length, varies the diameter of the coil former via its motor drive so that, during coiling of the cable or wire, the trailing end remains over in a certain predefined length.
In the context of the invention, coil formers are to be understood as meaning all those assemblies which are suitable for coiling a wire or a cable. A drive therefor is to be understood as meaning any - generally
electric - motor which rotates the coil former in a defined manner.
Variation of the diameter of the coil former is to be understood as meaning that the coil former geometry is changed so that the internal diameter of the coil is changed as a function of the geometry of the cable or wire piece, in particular as a function of its length, so that, on complete coiling of the wire or cable piece, a certain number of windings are wound onto the coil former and the trailing end then remains over in a certain length. Wire geometry and cable geometry are to be understood as meaning, inter alia, the external diameter of the cable or wire and its diameter form. Round cables and wires as well as flat cables and other special forms are included. However, coil former is also to be understood as meaning a "negative coil former", namely a coiling pot, which gives the coil its external diameter.
The knowledge of this geometry and length of the cable or wire pieces can be obtained by the computer control according to the invention directly via a communication interface, for example via a keyboard or a touch screen, or automatically from the respective control of the upstream processing apparatuses, such as, for example, an apparatus for cutting to length or a cut- and-strip machine (insulation stripping machine) . If appropriate, the corresponding controls may also be integrally formed or the commands for the diameter setting can also be taken from a superior control in the manner of a master-slave arrangement.
The invention achieves the set object in that not only
the leading end, which traditionally comes to rest at a predefined location, but also the trailing end comes to rest at a predefined location, for example parallel to the leading end or with a predefined length, e.g. the same length as the leading cable or wire end.
This effect according to the invention rests purely in the corresponding software or in the corresponding actuation of the drive for diameter adjustment and of the rotary drive for the coil former. Drive for diameter adjustment is to be understood as meaning any device which is suitable for adjusting the external diameter of the coil former and hence the internal diameter of the coil in a defined manner and under remote control or automatically.
The software or the mathematical principles on which it is based need not be specified for the person skilled in the art since the corresponding person skilled in the art is a mechanical engineer who is familiar with the relationship between diameter, circumference and the number pi. With knowledge of the invention, it is easy for any person skilled in the art to set up the corresponding formulas and to program the corresponding software or to have it programmed.
According to a particular development of the invention, a correction program is also provided in which, as a function of the result of the automatic coil diameter adjustment, the user can influence the software by input commands to enable the trailing end to be longer or shorter. Of course, this process can also be automatically monitored by monitoring the end position of the trailing end or that of the leading end - for
example optoelectronically - and automatically carrying out a readjustment by means of a control loop.
According to a particular development of the invention, a correction program is also provided by means of which the preselected cable tension can be taken into account during the coiling process.
The invention is visualized with reference to a schematic diagram (Fig.l) : it shows an axis 2 of rotation around which a coil former 1 with its coil arms is schematically indicated. This coil former (or its coil arms) is, according to the invention, variable in its diameter in a computer-controlled manner as a function of the cable or wire length and of the geometry of the cable or wire. The purpose according to the invention is accurately to position the leading end 3 and/or the trailing end 4 of the cable or wire relative to one another and relative to the coil former 2. According to a particular development, the cable or wire ends should be in the plane 5 parallel to one another and a certain distance 6 apart and should have the same length, i.e. the cable ends 3, 4 should be the same distance from the axis 2 of rotation.
However, the invention is not limited by the description of the figure and the claims. Rather, it also comprises embodiments which result from combinations with the contents of the following patent applications filed on the same date:
For the purpose of the combination of the device according to the invention or disclosed device, the patent applications (Applicant's references S73CH,
S75CH and S78CH) filed on the same date are hereby mentioned.
This combination is mentioned with regard to the grounds for priority of any later combined application.
In relation to S73CH, there is the following possibility for combination:
The device for binding with a tape is very suitable in combination with a coiler according to the invention. The coiler according to the invention can, for example, have the same mechanical design as that according to S73CH or S75CH.
In relation to S75CH, there is the following possibility for combination:
A coiler having a transport apparatus according to S75CH can easily be equipped with a device described above. The advantageousness arises especially from the fact that optimally wound coils can then be stored on a transport apparatus according to S75CH and can be delivered to a further processing apparatus.
In relation so S78CH, there is the following possibility for combination:
A coiler which produces ends true to position, as in the present application, is also very suitable for fixing the resulting coil by means of wire or tape according to S78. However, precisely a coil fixed in this manner in turn fits particularly well on a transport apparatus according to S75CH.
