Description

The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 10, a special coiling device for the devices according to claim 10, and a System according to claim 28.

A cable processing device in the sense of the invention is a device for processing a cable so that this on its surface or its geometry or in its position changed from the original state is. It usually has one along a cable feed axis arranged first cable feed device, a Cable processing tool (usually at least one knife, Crimping tool or a print head or the like.). Often ordered them over a second cable feed device, whereby both cable feeders the cable in at least one, often also against this first feed direction can move while the cable editing tool between the feed movements cable processing operations performs.

Cable processing machines are essentially understood a cable processing device for cutting and / or stripping and / or cutting a cable or at least one cable end of the cable.

The invention is not restricted to such a device. It also includes devices that only the cable sever (cutter) or transport (feeder).

Coiling means a device for Coiling a cable. It usually has one Coiling pan or a Coilingteller, in or on the a coil is created and, via a drive, the coiling pan or coiling plate drives. One coiling pan corresponds a coil plate with a peripheral wall lateral supports of a coil. In the description below both are to be understood as interchangeable. The coiling pans or coiling plates usually remain on site at the coiling device; for special Examples of such coiling pans or Coiling plate for further processing with the Coil stay connected, like pallets as a transport pad can be used.

Coiling is the coiling of one Cable. A coil is roughly circular in several layers stored cable. It is usually in several layers and has two cable ends (a cable section start and a cable section end), as a rule, however, no carrier or bobbin. Cable is understood in the context of the invention at least one electrical or light-optical conductor, which is externally insulated. typical Cable processing machines in the sense of the invention are so-called "Cut and Strip" machines or cutters like them e.g. under the designation CS 9050, CS9100, PS9500 Powerstrip or OC3950 launched by the applicant were.

Typical "cut and strip" machines have drive rollers, Drive belts or other drive devices, which is initially a cable along a first conveyor axis promote a transport direction and then in the course of the stripping processes again against the first in the opposite promote second transport direction to the individual Stripping steps - mostly on both cable ends of a cable section - perform.

Coiling is in the sense of a preferred embodiment the main invention primarily now such long, stripped at both ends or only cut, Form pieces of cable into a coil to them easier to transport, store or process close.

The SU-916012B describes a wire coiling machine a coiling pan into which a U-shaped one is used prior to coiling Tie tape is inserted to take out before of the finished coil to bind it and thus even more transportable close. The wire is turned by a Place the device in the pan. The structure is as Addition to wire rolling or wire drawing devices intended, where only one due to the production process Feed direction occurs.

US 4372141 describes another wire coiling device with an integrated cutting device for the wire. The feed speed of the wire is driven by two drive rollers driven by a gear generated. The feed rate is mechanical synchronized and varies with regard to the coil operation and the cutting company. The use of this wire coiling device as an addition to a cable stripping device is not scheduled. How does the SU-B work the construction with only one feed direction for the Wire.

Another form of synchronization (clock synchronization) between cable processing and coiling device is indicated in US 4663822 from 1987. Controls there only programmable electronic controller all Drives. A switch switches the cable path between two Cable channels to two selectable coiling pans. The two Coiling pans are powered by a motor via a clutch driven, which are optionally and alternately engaged or is solved. The electronic controller captured the cable feed and a length measuring sensor the position of the cable ducts via a proximity switch. It synchronizes the drives via the control of electropneumatic Spool. A spool moves e.g. the cable duct between two coiling pans assigned positions. Two more control pistons operate a clutch between the constantly rotating Engine and the coling pans. A clocked, synchronous Process is thus possible, provided it is during cable processing not to slip or feed losses comes. A game is possible in the coiling pans themselves, because the cables are shot in freely. unwanted Frictions or cable damage cannot be completely turned off. Free-flying insertion does not allow for exactly reproducible coil forms achieve.

An additional one, also controlled by the controller Disc brakes are provided around a rotating coiling pan slow down as soon as it is no longer driven. In this respect, this structure only knows two operating states of the Coiling pans: rotating at full speed or braked. An intelligently controlled drive with variable Velocities, acceleration moments or variable braking torque or feed reversal is despite electronic However, controller is not provided.

Apart from this, this structure is based on the operation or Programming is quite complex. So the only one Controller operated with all parameters relevant to results become. Reprogramming must take place if devices on the periphery (additional devices). But even if only operating parameters on the main tool or be changed at the feeds, corresponding must Changes in the operating parameters of the auxiliary devices be programmed by the operator. This is time consuming and in no way fault-tolerant. Before a corresponding Arrangement is workable, should each trial runs are made in which may with committee too to calculate.

The principle of a central computer for controlling Several cable processing devices also take place in the US 5343605 from 1994 application. There is a first data line there (command bus) to the upstream device and one second data line (command bus) to the "Cut and Strip" device. A data line runs from both devices to the computer back (status bus) is made by the computer, its program must always be adapted when another device is connected.

US-4546675, on the other hand, describes a complete cable cutting and stripping unit with connected coiler, which winds the cable on a lowerable mandrel. The mandrel is lowered to remove the coil. adversely there can be a frictional resistance between the Coil and the mandrel may affect to damage the Cable.

A support plate gets up along a cable feed nozzle and drove down to layer the coil in layers to be able to. A sensor measures the tension in the Cable and controls the traction on the Winding drum. So this older structure is opposite the US 822 theoretically more sensitive to the requirements of a cable when coiling. However, it is always reactive and can respond to rapid feed changes react only with a delay, what to bend the cable or can lead to excessive voltages in the cable. A feed reversal is not provided at all.

US-4869437 describes an apparatus for manufacturing a wire coil wound around mandrels arranged in a circle and at the same time from an outer circle of thorns to be led. To avoid removal problems a fully wound coil and for shaping coils with different diameters, the mandrels are eccentric stored so that they rotated about their eccentric axis can be while keeping the coil both on its inner as well as their outer diameter. When coiling itself is only a feed direction for the Wire provided.

US-4730779 describes instead of being arranged in a circle Thorns a stretchable bobbin for winding of paper tissue. After winding up the outside diameter of the bobbin and so the wound Tissue released. A lesson for an optimal Control of a coiling device after a cable processing machine cannot be derived from this.

US-4172374 describes a winding device for spring wires with a winding body made of two radially to each other sliding thorns (Fig. 9 and 10). A reference to the Use of movable mandrels in coiling devices is missing.

US-4669679 describes a cable cutting device connected coiling device with two coiling pans with a central mandrel each, around which with the help of conveyor belts "free-flying" a cable is wound. The cable is not loosely inserted and also not clamped to to wrap the thorn, but from the conveyor belt to the Thorn held down. Give both mandrel and conveyor belt Feed. This leads to the winding of the cable. there the wire feed nozzle is moved along the mandrel height in order to to achieve a multilayered ordered cable layering. The The movement of the nozzle is speed-coupled with the movement the conveyor belts. The speed of the cable feed through the cutting device and into the coiling device is kept constant. That by cutting each new cable end that is created is automatically inserted into the headed each other coiling pan so that the full Coiling pan can be emptied in the meantime. Since the Cable processing consists only in cutting the cable, there is no consideration of a feed direction reversal here either.

To avoid bending the cable are in feed channels Spring flaps arranged to bend the cable prevent. The winding body is in its outer diameter can also be reduced to make it easy to remove the coil to enable.

Incidentally, this US patent 4,669,679 quotes the extensive State of the art, which in this application as well quoted applies.

In addition, the following publications have emerged from the prior art considered: EP-B-330840, US-4881393, EP-A-584493, EP-B-396068, EP-A-864524 which, however, are not significant Offer solutions to the problem below.

A coiling device with a cutting device (no "Cut and Strip" but only "Cutter") is in US 4026483 specified. It has a gear controlled feed nozzle, which controls the cable layer by layer on the bobbin applying. Here, too, the cable only runs in one feed direction.

US-5063974 describes an automatic wire cutting coiling and binding system for the production of multiple wire bundles, where, among other things, a motor-driven Coiling device with a pneumatically operated clamping device to wrap the wire end around the mandrel. As well a guide roller is provided which has an annular Has guide groove for a wire depending on this of the desired inner diameter of the coil. A stripping device is not provided. The In the absence of a back and forth movement of the Wire are carried out without interference. The speed of rotation of the Coiling device can - due to lack of change in feed direction - can be easily coordinated with the feed rate.

Another form of clamping the wire or cable end can be found in a coiling device from Ramatech, where a clamping fork with conically converging Clamping bracket picks up the cable end. The clamps effect a self-clamping, but the clamping point is not positive is defined so that it also slips through the cable can come. The Ramatech arrangement also requires this manual threading of the cable end into the clamping device.

US-5374005 and US-5575455 describe a coiling device, where an optical fiber into a coil is placed in a coil pot by blowing air is blown from a nozzle into the rotating pot and loosely wraps around a thorn there. This procedure is only applicable for thin, light cables. The one achieved Coil is not exactly reproducible.

US-5485973 describes a comparable system for stronger cables that go through a gooseneck from the center of a coil pot are placed in it while rotating. However, this is not a coil system for Manufacture of removable coils, but around a cable storage. A pressure roller presses the inserted cable rings against the base plate so that it is as tight as possible to be arbitrated. Without the pressure device would be a systematic filling of the cylindrical ring Cavity of the coil pot is not possible. Because of the Gooseneck and the pressing device is the removal a coil or a coiled cable is not possible.

EP-A-474152 describes a cable processing machine, in which a pivotable, tubular cable routing device a cable from one processing station to one pivots in the subsequent processing station. Such Cable guides are also used in known coiling devices used with more than one coiling pan.

U.S. 4669679 describes e.g. such a coiling device with two coiling stations so that during one coil is removed from one station, in the other coiling station a next coil is generated. There, however not the cable duct, but an upstream one Switch adjusted to the cable of the correct coiling pan be forwarded.

The applicant brought one under the designation CP1250 freestanding coiling out, which is also about has two coiling pans, which also have two separate ones Alternating guide tubes with upstream switch Cables can be inserted. The coiling pans are rotated by motor, so that shooting Cable through the friction on the coiling pan wall taken away and put down to a coil. Downtown the coiling pans are fitted with mandrels that prevent that cables are stored in a shape that differs from the circular shape can be. The drive of the coiling pans is adjustable, so that every user his "optimal" speed can choose. This is usually something set faster than it necessarily regards the discarding speed or shooting speed the cable into the coiling pans would be required. This for security, to a stall of the cable feed and one Bend the cables out safely.

The CP1250 is therefore in contrast to others conventional coiling devices that try the Rotation speed of the coiling pans or other winding devices to adapt to the needs, e.g. the cable tension is measured and based on the measurement result the drive accelerates (tension drops) or braked (tension increases).

Both known methods are therefore oriented indirectly at the processing speed in front of the coiling device. As mentioned, the CP1250 uses e.g. a faster Rotation chosen as resulting from the previous processing would result; and with the tension measuring systems by means of Control loop for changes in delivery speed, which are detected by changes in tensile stress, reacted and adjusted the speed.

Both known methods have disadvantages: While there is a slip associated with one There is friction, which leads to grinding marks on the cables the other method can lead to irregularities, to bend open or unwanted tightening, if the control loop reacts too slowly. A sudden Elongation stress can disadvantageously affect the mechanical, electrical or optical properties of a cable negative influence.

The object of the invention is thus a new method or to find a new device that the known Avoids disadvantages and a uniform, accurate Control of two or more cable processing devices, e.g. of accessories on "cut-and-strip" machines allowed, e.g. the draft-free or with a defined train, reproducible laying of a cable to a coil allowed, without other known from the cited prior art Show disadvantages.

The combination of the features of claim 1 solves this Main task in a corresponding procedure. The The invention is not restricted to combinations of stripping machines with coiling machines. It relates generally refer to cable processing machines with functions, as specified in the claims. Through the basic independence from cable processing devices from each other and by assigning one each Program control, the invention breaks completely new ground. As The main advantage is that the new programming of the Program control of the stripping machine previously treated as the main unit.

Various things can be done on one cable processing device Additional devices can be connected, which are the required Get information from the first device and if necessary Return status information without, however mandatory in a rigid "master-slave relationship" from the first program control to be controlled. In the invention the "master-slave ratio" can change as needed - also several times in a row - reverse, or entirely omitted. For example, a standard command "feed 10m / s "in a first program control for the feed drive on a "cut and strip" machine in one over one Interface downstream coiling device via a second program control either the drive for a Rotation of a coiling pan to a comparable one Accelerate feed rate (slave ratio). However, it can, for example, be the second program control also report back automatically to the first program control: "This feed is too fast for a coil process, reduce the feed to half "(master ratio). The example given reduces the scope of protection of claim 1 not. It covers all types of cable processing devices in the sense of the invention.

Claim 2 represents the same according to the invention Basic ideas or the same inventive concept ab, but relates in particular on stack coiling or unwinding devices as cable processing devices (Additional devices) on other cable processing devices.

The dependent process claims 3 to 9 give special, further developed process steps.

The independent claim 10 aims at a composite Device made of new cable processing devices, that generally solves the tasks.

Claim 12 gives an important change compared to conventional Stripping devices on an inventive Formation of a device according to claim 10 facilitated.

Independent claim 28 indicates a system with the cable according to the invention can be processed.

The remaining dependent claims 11 and 13-27 provide improvements, Further developments or variants of the invention on.

In addition to the control aspects of stripping devices, the invention also includes but also new types of training Coiling device, which in principle is also independent of the control aspects could be used.

This is how it works e.g. for a positive detection and clamping of the Cable end in a coiling device - albeit the does not necessarily have to look like a conventional one Coiling pan, but e.g. even without side walls can get along, e.g. a coil plate - and more Improvements to coiling devices. The following will each referred to "coiling pans", -with it also "Coilingteller" or the like. are included.

When controlling a coiling device drive in Dependence on the program control of the cable drives an upstream cable processing device, it goes especially about the characteristic properties or Movements of the cable processing device or transported cables, e.g. Inertia, start-up and Braking behavior, feed and retraction etc.

Any feed directions are possible with the invention, start ramps and the like are also berücksichtigbar. This leads to reduced interference behavior and accurate coiling. The coils are independent of that previous cable processing reproducible, uniform than was previously possible.

According to a special embodiment of the method the program programmable so that along with the programming the cable processing machine also the drive the coiling device can be freely programmed.

According to a special embodiment of the invention which is a special data transfer unit - in this Case as an interface between the two connected devices trained (e.g. a FELD-BUS, especially a CANBUS - preferably CAN-SELECTRON - PROFIBUS, INTERBUS-S, AS-BUS, LON, ARCNET, EIB, ETHERNET) - that status information from the main device to the auxiliary device, and vice versa, e.g. from the coiling device to the program control of the first cable processing device and from there on Display will be delivered. In the text below and in the Claims will only ever refer to the FIELDBUS taken, but all the bus systems specified above encompassed.

Basically, the additional device (e.g. the coiling device) or its program control on its own Keyboard programmed. If necessary, are on the data transfer unit or via the interface and the first Program control, however, also program commands of the first Cable processing device possible, so that from the keyboard the cable processing device both this and the coiling device drive is programmed at the same time can be and on a possible display also the Setting values of the coiling device drive can be mapped are. On the other hand, variants are within the scope of the invention with its own display on the additional device, on which e.g. Status values of the main device can also be displayed, which are direct can be delivered via the interface.

It is the coiling device drive according to the invention therefore not - as is already known in the prior art - for a timed control of cable processing and Coiling device, but it's about an intelligent Activate the coiling device so that it is complete compatible with the cable processing machine runs. The means that a non-clocked movement of the Coiling device is possible. For example: the known one in advance The coiling pan can start up the stripping machine already program controlled by the electronics in Put movement, so pressure-voltage peaks of the pushing To prevent cables.

Table-based are therefore also within the scope of the invention Approach ramp controls for the coiling device drive, help to optimally reduce the tension changes in the cable. Special training variants are within the scope of the invention thus also braking and speed reversing operating modes for the coiler drive, etc.

Further improved solutions with further user security and further advantages compared to the stand The technology results from further technical details the new coiling device.

A controlled cable clamping device provides a safe one Clamping the cable end or beginning securely and enables the creation of reproducible coils. A fully automatic Coiling is possible if according to further training the invention, the cable feed to the coiling device program and / or position and / or sensor controlled. Especially for binding the This is beneficial to coils.

A sensor according to the invention is in a controlled one geometric relationship to the coiling pan or to the coil plate. It is preferably attached to a sensor arm that in a certain geometric relationship to a programmable Cable duct is available so that it e.g. the result of the cable feed through the cable duct monitor - or feed back - can. Apart from this Such a sensor could also be developed in a special way the geometric structure of a cable and / or one Record or control coils. Are preferably located Sensor arm and cable duct on a common axis, however axially offset from each other.

The interaction of cable duct and drive for coiling pan according to the invention is designed such that that after creating a coil that free cable end temporarily in the cable duct can remain. Thus, both the beginning of the cable Coils and the cable end can be reproduced under program control geometrically defined and stable in shape kept what binding as well as automatic further processing, the coil (e.g. transporting).

Known winding mandrels are used in a further development the invention preferably as a radially displaceable Mandrels provided that the wound coil when removing lead without tension. Preferably either Thorns can also be lowered or a base plate -the Coil carries, can be raised so that there are spikes and move the base plate relative to each other and thereby the coil is easier to remove. Raising the floor slab may be preferred insofar as such Coil is lifted up to the operating staff, whatever its Removal made easier.

The sensor-controlled according to a further development Determination of the coil diameter building up allowed automatic control of the speed of the coiling pan drive, around the cable speed on the coiling device the speed of the cable processing machine adapt. As an alternative to measuring the coil diameter e.g. by means of a light barrier, for example respective power consumption on the coiling pan drive as Measure for the speed regulation can be used. On known methods, such as the measurement of tensile stress in the Cables would also be conceivable, but due to the delayed response time is not preferred.

Double coiling devices known per se allow one continuous cable processing and coiling, with preference a new switch that is also independent of the rest Features of the invention would be applicable. Instead of known switches, which have a single inlet funnel with two different outputs, of which one or the other by swinging the Turnouts that have been positioned are now program-controlled two independent cable routing channels are provided, each of the cable exit of the cable processing machine be compared - especially by vertical or horizontal shift. This will result in higher operational reliability reached and jamming or misdirection of the cable avoided.

According to a special embodiment, the cable switch also removable by hand or motorized, so that any Reject production can be automatically ejected can. At least manual removal makes it easier Cable insertion and service work

A motor-controlled and preferably sensor-controlled one according to the invention Cable management arm increases the coil quality than he program-controlled the coil structure in cooperation with of the rotating coiling device. Multi-layer structure, but also end positioning of the second cable end or the end of the cable piece are solved optimally. Particularly in connection with a new one according to the invention exact detection of the rotational position of the coiling device, is such a final positioning of the coil for removal purposes simply possible.

The arrangement of two cable processing devices is within the meaning of the invention not limited to serial Arranging these devices so that cable processing strictly one after the other along a general Feed line takes place. Are recorded in particular also parallel cable processing, where e.g. a cable laterally offset from its general feed line or is pivoted and there by another cable processing device is processed and then again is swiveled or moved into the feed line.

Further improvements and details according to the invention result itself from the drawing, which is an inventive embodiment represents.

Fig.1 and Fig.2 point to a superordinate principle of Invention: Two basically equal cable processing devices 1 and 2 (several can also , as not shown), are via a data transfer unit 5a (own program control or computer) or 5b (special interface, e.g. FIELDBUS, etc.) with each other connected or connectable. Each of the cable processing devices 1,2 has its own program control 3,4 in contrast to the known with a central program control in a main unit. These program controls 3,4,5a can be influenced by any keyboards provided 6a, 6c or 6d or the like. They can also be influenced if necessary by feeding in measurement data from sensors or the like. (7a, 7b).

One of the innovations is the second program control 4 a program with arithmetic operations (symbolically with 24 indicated), the pure status or parameter data from the first program control 3 control data for the Calculate the second cable processing device 2. This Control data are fed to a controller 11 which e.g. drives a drive 25. The drive 25 is symbolic via a control loop 6b or the like. fed back so that at Requires the real drive data via the data transfer unit 5a or 5b as status information of the first program control 3 are made available for information.

The first program controller 3 could, in the context of the invention, as shown in the second program control 4, also have corresponding arithmetic operations (24), however, as is not shown in this example.

The symbolic keyboard 6d in Fig. 1 enables this Embodiment influencing the data transfer between the two cable processing devices 1 and 2.

3 shows a coiling device constructed according to the invention 2a on a frame 26. It comprises a housing 27, a connection field 28 for the energy connection (electricity, Compressed air or the like), a display 29, a keyboard 6a, a symbolically indicated program control 4a with a Interface 5b, a controller 11, two coil plates 8a and 8b and a cover 20, which is optionally a coil plate 8a - as shown - or the other coil plate 8b covers. A safety circuit prevents that Coiling operation of a coiling plate 8 when the cover 20 is missing.

The cover 20 is motorized via a spindle shaft 29 controlled, as can be seen from Fig. 6. Two limit switches 30a and 30b are part of the safety circuit according to the invention.

In the rear part of the coiling device 2a is on the housing 27 a cable switch 16 is mounted which can be swung out according to the invention is. For this purpose, a gag 31 can be released, whereupon the Cable switch 16 can be tilted about a pivot axis 32. By this tilting the two cable feed channels 17a and 17b from the area of the outlet 18 of a cable processing machine 1a removed. In the tipped state always one of the two cable feed channels 17a or 17b Exit 18 opposite. A motor adjustment 33 (compressed air or electro controlled) ensures program controlled for the correct positioning of the cable feed channels 17a or 17b, the other ends each with a cable feed arm 10 are connected, one of which is the right coil plate 8b and the other assigned to the left coil plate 8a is.

The Coilingteller 8 comprise a bottom 14, the latter Embodiment (not mandatory) removable spacers 15 wears. A coil snaps onto these spacers 15, so that an operator or a transport device or a binding device can reach under the coil.

It also includes motorized (pneumatic) actuation Winding mandrels 13, which are shown in the coil removal state are. In the winding state, these mandrels 13 are radially outward shifted so that it has the inside diameter of the coil define. One of the mandrels 13 cooperates with one Cable clamping device 9, which programmatically controls one cable end can clamp to precisely define the start of the coil.

The cable feed arm is spatially assigned to the coil plate 8b 10, which is connected to the cable feed channel via a plastic hose 17b is connected. A comparable arrangement is also provided for the coil plate 8a. The lifting or lowering the cable switch 16 thus leads to the manufacture a connection from the output 18 to the cable feed arm 10 or to the cable feed arm at the coil plate 8a.

The cable feed arm 10 is on a cable guide arm 19 mounted, the program-controlled on an axis 21 - comparable a turntable arm - is pivotable. additionally if necessary, he is still controlled in height adjustable. A coil can be controlled in this way wrap.

This winding process is monitored by a light-optical one Sensor 7a on a sensor arm 34, which is axially offset to the cable guide arm 19 is mounted on the same axis.

Fig. 5 shows the exploded structure of this embodiment with its swivel drive 35, its housing 36 and the controller 11 for the swivel drive 35 and other drives the coiling device 2a.

The cable guide arm 19 can be attached to a holder 37 can be mounted above or below. The height of the bracket 37 corresponds according to the invention to the height of the spacers 15, so the cable management arm 19 depending on the presence the spacer 15 at the top or bottom of the Bracket 37 is mounted.

The cable processing machine 1a is only symbolic in FIG indicated with a cable feed unit 22. she could e.g. by a "cut and strip" machine, e.g. one Powerstrip 9500 of the applicant.
