Abstract

A winding system has a common feed for parallel strips of material for winding onto a bank of reels mounted coaxially on a support frame. At least one reel has a separate mounting to allow reel change without interrupting the winding action for the other reels. The reels mountings are slid laterally to move the reels out of line for easy access. The sliding action requires less effort than a tilt action and can be performed manually and the drive to the reels is automatically uncouple when the reels are slid out of position.

Description

The invention relates to a winding device, in particular for a winding machine, which has a coil stand in which a number of coils are juxtaposed can be used on the successive one of the take-up fed via a threading material web can be wound by the Coil-carrying coil stand displaceable transversely to the feed direction of the material web is.

Such a winding device, in particular for a winding machine, is known from the earlier patent application Aktz. 00 108 733.7. It is intended that in order to facilitate loading and unloading of the take-up device allow at least one of the coils can be used in the coil stand independently from other coils from the winding position, where the coil is the material web can be fed, by a in the feed direction of the web and thus substantially transverse to the sliding direction of the coil stand Moving to a loading position where the spool can be inserted into the spool holder or is removable from this, is movable so that in the corresponding Coil holder this coil is pivotally mounted. Such Pivoting movement of the spool for its movement between loading and unloading position is sufficient for a variety of applications. Problems occur but then, when heavy coils are to be moved, as in the known Device o. G. Movement performed by pivoting the coils must become.

Another winding device for a winding machine is known from DE 85 34 634 U1 known. It is provided that on a common, the coils driving, mounted in a coil stand shaft a plurality of coils used and be rotated by the common shaft. After a Coil was wound with the material web fed by the winding machine, the material web is cut off and the coil stand is cut off by the distance moved further between two adjacent coils, so that the material web now can be wound on the coil next to the full bobbin. After this all coils arranged on the common shaft were fully wound, it is disadvantageously necessary that the winding machine in order Interruption of the supply of the web must be stopped to the full To remove coils from the common axis of the winder and put new, empty spools on the common axis. typically, This unloading and loading process of the coils takes about one third of the Fully winding the coils with the material web required time, so that in disadvantageous Way in the known winding device for a winding machine an inadequate efficiency is given.

Another disadvantage of provided in the known take-up Arrangement of all coils on a common axis is that - if a complication occurs in an internal coil - all in axially outward coils must be removed so that the inner coil is accessible. This fact also adversely affects Way the efficiency of the known winding device.

From DE 34 25 148 C2 a device for winding a roll is known having the pivotable in a winding machine holding arms. The holding arms can be moved along a guide over the working width of the machine and pivot about this guide, so that different width roles can be wound. For winding motors are provided, which are each secured to the associated pivotable support arms. Every engine drives in this case via a traction mechanism to the respective wound-up role. It is provided that the waves of adjacent rollers connected to each other be by one of the end face of the forming role facing away from the end at least two waves on the forming role rotatable about the supporting Retaining arm is extended out, and at each extended end of the respective Shaft is a part of a releasable coupling fastened, the coupling parts mutually facing parts of adjacent winding stations either with each other are connectable.

From DE 199 18 744 A1 is a winding device for a winding machine known, in which about a common shaft pivotable coil holders are provided. This rewinder is used on each spool holder a coil arranged so that the individual coils around the common The shaft can be swiveled from its winding position into a loading / unloading position are. Although this winding device has the advantage that the individual coils can be used independently of each other in the coil stand or from this are removable, it is disadvantageous, however, that a pivoting at very heavy, full bobbins or not realize only with considerable effort leaves.

It is therefore an object of the present invention, a winding device, in particular for a winding machine of the kind mentioned in the beginning, that even with very heavy coils loading and unloading the take-up is relieved.

This object is achieved in that at least one of in the coil stand usable coils independent of the other coils from a winding position, in which the coil, the material web can be fed, in the Feeding direction of the material web and thus substantially transversely to the direction of displacement the coil stand in a loading / unloading position in which the coil can be inserted or removed from the coil holder, is displaceable.

The inventive measures is achieved in an advantageous manner, that the at least one coil - after they in their winding position with the web fed by the winding machine was wound - especially can already be removed from the take-up while or after another spool is moved to its winding position by the full spool is moved to its loading / unloading position.

Advantageously, to move a coil now much lower Forces required, as for the well-known in the art pivoting since when pivoting a lifting work must be done, which in a move eliminated. In particular, be moved by the invention a full coil also known in the prior art panning occurring torques avoided. This has the advantage that the coil stand is exposed to much lower loads and therefore cost is executable in a lighter construction. While for a panning very heavy coils almost necessarily a corresponding drive necessary is, even very heavy coils - because no lifting work be done must - in principle by hand or possibly by a comparatively low power Move the engine.

The winding device according to the invention has the advantage that its fully wound Spools can be removed and replaced by empty spools while another coil of the winder is wound, so that in extremely advantageous manner the efficiency of the winding device according to the invention significantly increased compared to the known winding devices is.

Another advantage of the winding device according to the invention is that they only has a comparatively small footprint. In and of itself it is sufficient the loading / unloading position, in which the coil can be inserted into the coil holder or from this is removable, a coil diameter - or at a correspondingly large lateral distance between adjacent coils even Less - provided spaced from the winding position, so that only one corresponding short displacement and thus little space is needed.

An advantageous development of the invention provides that at least one of its winding position in its loading / unloading position movable coil on a Coil holder is mounted, which are preferably formed on a rail Guide is slidably guided. This measure according to the invention has the advantage that thereby a simple and inexpensive way is given, the inventively provided displaceability of the coils of Rewind device to reach.

A further advantageous embodiment of the invention provides that for all or almost all of the usable in the winding device according to the invention coils as a coil holder a displaceable arm is provided. This invention Measure has the advantage that in this way all or almost all coils of the rewinding device according to the invention independent of the other coils are manageable.

A further advantageous embodiment of the invention provides that at least a coil holder carries more than one coil, so that of a coil holder carried coils independently of the others in the coil stand recorded coils from its winding position to its loading / unloading position are movable. Such a measure provides that by the preferably Paired arrangement of at least two coils on a common Coil holder the number of in the reel stand of the winding device according to the invention be provided coil holders can be reduced.

A further advantageous embodiment of the invention provides that a coil drive is provided for driving at least one coil. This coil drive can each be provided on the coil holders or on a Be attached body, opposite which can be used in the coil stand Spools are displaceable. Preference is given to the latter alternative, since in this way a single drive is sufficient, which in each case with the winding coil or its coil holder comes into operative engagement. Especially it is preferred to form the coil drive as a friction wheel, which has a friction wheel which is in operative engagement with the spool or one with it cooperating friction disc can be brought. Such a friction wheel drive has the advantage that the friction wheel by a transverse displacement of the coil stand transverse to the feed direction of the material web without problems with the friction disk of next coil can come into operative engagement, so that wound another coil can be. For a good power transfer from the friction wheel to the coil, it is preferred that the coil drive by a pressing member against the coil or a cooperating friction disc is depressible. In itself can with the friction wheel, the coil are driven directly. For coils of inferior quality, For example, from cardboard or paper, however, it is difficult with the friction wheel To press a sufficient contact pressure against the coil, without this to damage. In these cases, a friction disc is preferably provided, which in operative engagement with the friction wheel and cooperating with the spool. Around with the friction wheel drive coils of different diameters to drive can, is preferred, the friction wheel vertically displaceable, in particular on one Sled, attached to the body, opposite which in the coil stand usable coils are displaceable. Additionally or alternatively Advantageously, the friction wheel may be provided on a pivot arm, so that the Friction wheel is pivotable with smaller coils to the coil.

Further advantageous developments of the invention are the subject of Dependent claims.

The illustrated in the figures first embodiment of a generally with 1 designated take-up device has a coil stand 2, in which a Number of coils 3a-3d is receivable. The coils 3a-3d become successive wound with a material web (not shown), which has a swiveling Threading head 5 are supplied. In this case, it is preferably provided that the threading head 5 is designed and arranged so that it is an increasing Diameter of the wound material web follows. After the first Coil 3a is fully wound with the fed via the threading head 5 web was, the web is cut off and the coil stand 2 is from a not shown in the figures, known displacement device (in Figure 1) to the left, ie in a direction transverse to the feed direction of the web Move direction, moved. The second coil 3b is then before the Threading head 5. Then, the second coil 3b is wound. After the second Reel 3b is full, in turn, the material web is cut off and the coil stand 2 again moves to the left by the distance between two coils, so that now the third coil 3c comes to rest in front of the threading head 5. This method will continue until all of the coils 3a-3d wound are.

In order not now - as in the known Aufwickelvorrichtungen - forced to be to stop the feed of the material strip, after also the last of the Coils 3a-3d has been fully wound, is in the described winding device 1 provided in an advantageous manner that at least one, preferably but all or almost all of the coils 3a-3d from their Wikkelposition shown in Figure 1 are displaceable in a loading / unloading position, as shown in FIG 2 is shown for the coil 3d. The coils 3a-3d are for this purpose in a in the Feeding direction of the web and otherwise substantially transverse to the direction of displacement of the coil stand 2 extending direction of movement from her Winding position to its loading / unloading position (and vice versa) by means of its in formed as rails guides 126 guided coil holders 10a-10d postponed.

Such a measure has the advantage that in this case with the removal z. B. the first coil 3a can already be started while the second coil 3b is wound with the material web. In a corresponding manner, the full second coil 3b are removed from the coil stand 2, during the third coil 3 c is supplied to the wound material web, etc. After the last coil 3d was wound, stands for the winding process of the material web at least one empty coil 3a-3c inserted in the meantime, so that by a simple displacement of the coil stand 2 to empty Coil - z. B. the coil 3a - the winding without major interruptions can be continued. The intended mobility of one or several coils 3a-3d independently of the other recorded in the coil stand 2 Coils 3a-3d thus has the advantage that, as a result, these coils 3a-3d are independent from the other coils 3a-3d manageable - z. B. for loading or unloading - are.

Advantageously, a shifting of the coils 3a-3d can be done even with very heavy Also cause coils by hand or with a relatively weak drive, because in contrast to a pivoting only inertial and frictional forces must be overcome, but no lifting work is to be made. In order to allow the easiest possible movement of the coils 3a-3d, are the coil holders 10a-10d in rails formed as rails 126 slidably guided.

In the embodiment, it can be seen that for each of the in the coil stand. 2 accommodated coils 3a-3d, a coil holder 10a-10d is provided. This but is not mandatory. It is also possible that only for almost all or only some of the coils 3a-3d, a coil holder 10a-10d is present.

It is also possible that a coil holder 10a-10d more than one coil 3a-3d, in which case it is preferred that a coil holder 10a-10d then preferably carries a pair, two pairs etc. of coils, preferably are arranged symmetrically on the coil holder 10a-10d.

It is preferred that the coil holders 10a-10d - as shown in Figure 4 - each having an arm 11, the coil 3a-3d at its first end 11 ' carries and attached at its second end 11 "on the carriage 130 (Figure 1) is, which slidably mounted on the guide 126 formed as a rail is. At its first end 11 ', the arm 11 and thus the coil holder 10a-10d a coil drive 20, on the shaft 21, the respective coil 3a-3d is stored. The coil drive 20 is - as best seen in FIGS to 6 visible - via a transmission element - in the case shown here via a Belt 23 - connected to a coupling element 24, through which the Coil drive 20 for the coils 3a-3d with the drive 6 respectively driven Shaft 15 of the winding device 1 is connectable. The education of a Coil holder 10a with such a coil drive 20 has the advantage that thereby the coils 3a-3d of a coil holder 10a independent of the on the other coil holders 10b-10d mounted coils 3b-3d rotatably driven are. It is possible that in each case only that coil 3a-3d weiterbewickelt while the other coils 3a-3d - in alignment of a coupling element 24 - stand still. In addition, it is possible that the next to be gewikkelnde Coil is already ramped up in its speed while the previous one Spool is still being filled. This embodiment has a particularly rapid Change between the coils 3a-3d.

By the measures in a manner a winding device. 1 formed, which is particularly suitable for a winding machine through which more than two coils can be wound. The inventively provided mobility one, some or substantially all of the held in the coil stand 2, three or more coils 3a-3d between their winding position and their Loading / unloading position is an advantage, as it allows a particularly simple independent handling of the individual coils is ensured.

In order now to be able to drive the coils 3a-3d in rotation, it is provided that the Coils 3a-3d are each mounted on a shaft 21 of a coil drive 20, via a transmission element in the form of a belt drive 23 with a Coupling unit 24 is connected to the respective shaft 15 of the respective Coil holder 10a-10d can be coupled.

FIG. 7 shows a second exemplary embodiment of a winding device 1 illustrated, which is its basic structure according to the first embodiment of Figures 1 to 3, so that corresponding parts with the same reference numerals can be provided and not described in detail Need to become. The main difference between these two Embodiments consist in the manner in which the coils 3a-3d rotate become. While in the first embodiment - as best is apparent from Figures 4 to 6 - is provided that the coils 3a-3d are driven via a respective spool drive 20, via the belt 23 and the coupling element 24 with the respective rotationally driven shaft 15th is connected, it is provided in the second embodiment that the drive the coils 3a-3d via a designed as a friction wheel drive further coil drive 120 takes place. The further coil drive 120 has one of a closer shown drive device driven friction wheel 121, which with a on one of the coils 3a-3d attached or connectable with this friction disc 124 or the coil 3 a - 3d interacts directly. The further coil drive 120 is disposed on a carriage 125, which in a guide 140 in vertical Directed displaced. This makes it possible, coils 3a-3d different Diameter with the common coil drive 120 to drive. The friction wheel 121 is provided on a pivot arm 129 which passes through its pivotability also to the adaptability of the coil drive 120 at Contributes coils 3a-3d of different diameters.

The operation of the coil drive 120 is as follows: When the coils 3a-3d are in their winding position, the coil drive 120 by a pressing element, which works electrically, hydraulically or pneumatically, against the coil to be driven, in the case shown here against the coil 3c, pressed and the friction wheel 121 is rotated. The friction wheel 121 is in this position in operative engagement with a larger outer diameter than the one to be driven Coil 3a-3d having friction plate 124, whereby the to be wound Spool 3a-3d is set in rotary motion.
