Abstract

A device for winding or unwinding web-like or tape-like materials (35) such as paper, films, textiles or the like is proposed, winding shafts (23) being provided which can be motor driven, are mounted rotatably, at least on one side, in sliding bearings (18) and can be moved and positioned individually along a self-contained guide path. A rotationally drivable guide drum (14), on which the sliding bearings (18) are guided in a freely displaceable manner, forms the guide path. Fastening devices which can be actuated independently of one another are used for fixing the sliding bearings (18) to the guide drum (14). For fixing the axle of rotation of the winding shaft to the machine, which shaft is in each case moved to a determinable winding position of the guide path, use is made of a holding device (33) which acts in accordance with the corresponding actuation. In this manner, the winding shafts can be moved independently of one another along the guide path, so that an automatic change of winding shaft is possible with short, free web lengths, without stopping the flow of material. <IMAGE>

Description

The invention relates to a device for unrolling or rolling up web-like or tape-like materials such as paper, foils, textiles or the like. With motor-driven winding shafts that are rotatably supported on at least one side in sliding bearings and that can be individually moved and positioned along a self-contained guideway are.

In such a device, known from EP-OS 014 5029, the winding shafts are individually movably guided and positioned in a rigid guide frame. You will need drive motors for the winding process and for positioning. In the known device, only short free web lengths occur in an advantageous manner, a flying reel change and thus a continuous mode of operation being possible nonetheless. With the great variability of the control and individual positioning of the winding shafts, the design and costs are not insignificant.

It is therefore an object of the present invention to provide a device of the type mentioned at the outset which has similar advantages to the prior art mentioned at the outset, namely allows only short free web lengths to arise during the winding process and enables flying reel changes, which, however, are structurally simpler and can be built more cheaply.

This object is achieved in that at least one rotationally drivable guide drum forming the guideway is provided, on which the sliding bearings are freely displaceable, that the sliding bearings are provided on the guiding drum and can be operated independently of each other and that the axis of rotation of the in each case a winding shaft which is fixed to a definable winding position of the guideway is provided with a correspondingly actuated holding device which fixes the machine.

At least the winding shafts involved in the winding process and the removal process of the finished wound roll can also be moved and positioned independently of one another in this structurally simpler device. Positioning drives individually assigned to the individual winding shafts are not necessary, since the positioning drives fixedly arranged on the machine frame can shift any or several of these winding shafts. The guideways designed as guide drums and the machine frame serving as the bearing point can be constructive be very simple. Nevertheless, a variable and individual winding process is possible, in which long free web lengths can be avoided, which can lead to wrinkles and a course of the edges with stretchable materials.

Advantageous further developments and improvements of the device specified in claim 1 are possible through the measures listed in the subclaims.

In a structurally particularly simple embodiment, a single, rigid guide drum is arranged on an outwardly extending drive shaft in the lateral region of the winding shafts outside the path of the materials to be wound. This simplifies the drive device for the single guide drum in a special way.

A more variable construction is achieved in that a single guide drum consisting of an inner and an essentially concentric outer area is arranged in the lateral area of the winding shafts outside the path of the materials to be wound, so that one area is designed to be drivable independently of the other area. that the sliding bearings are preferably guided so that they can move freely between the areas and that on each sliding bearing these are optionally provided with fixing devices which fix the inner or outer area. This will be an advantageous constraint guidance of the sliding bearing reached. Furthermore, e.g. the inner ring can be machine-fixed and the outer ring drivable, for example via an externally acting drive. Those sliding bearings that have to be positioned stationary can be fixed on the fixed inner ring, while the sliding bearings to be transported are fixed on the rotating outer ring. Of course, this can also be done in reverse. In the case of a rotating outer ring and at least three sliding bearings, the centering of the outer ring can take place on the fixed inner ring. An even greater variability is achieved in that both areas of the guide drum are designed to be drivable independently of one another.

In order not to overload the one-sided bearing points due to the great weight of a completely wound roll, the latter is guided on a guide segment which essentially extends from the winding position to a removal position for rolled-up material and which guides the free end of the winding shafts mounted on one side in sliding bearings. When the removal position is reached, it can be pivoted or moved to enable easy removal of the roll.

For safe and exact guidance of the roll from the winding position to the removal position, at least one guide gripper, which is pivotably driven about the axis of rotation of the guide drum, is expediently adjustable for gripping one winding shaft each radially to this axis of rotation. forms. For this purpose, the guide gripper or grippers are moved axially against the winding shaft located in the winding position, the end of the guide gripper which grips the winding shaft being preferably designed as a half bearing, while the counterbearing is formed on one winding shaft side by the guide drum and on the other winding shaft side by the guide segment will. For this reason, two guide grippers in the area of the two ends of the winding shafts have proven to be particularly favorable.

For safe and precise guidance, the winding shafts are rotatably supported on both sides in sliding bearings guided on two guide drums. The guide segment and the guide grippers can thus be omitted. Both the unwinded and the wound winding shafts are safely supported on both sides in every position. In the simplest case, the two guide drums are arranged on a common, continuous drive shaft. If the continuous drive shaft in the middle area between the two guide drums proves to be disruptive, these can also be arranged on separate drive shafts, each of which runs outward and are synchronously coupled to one another in terms of drive, in particular via a coupling shaft arranged parallel to the axis of rotation, which is connected to the two separate drive shafts or is connected to the two guide drums via synchronous drives. The space between the two drums can thus be fully utilized, that is to say that larger rollers can be formed with a relatively small diameter of the guide drum.

A more versatile and variably controllable arrangement results from the fact that the guide drums each consist of an inner and an essentially concentric outer area, that an area is designed to be motor-driven independently of the other area, and that the sliding bearings are preferably freely displaceable between these areas are guided and that on each sliding bearing this is optionally provided on the inner or outer fixing fixtures. One of the two areas, preferably the inner area, can be fixed in a machine-fixed manner, or both areas can be designed to be driven by a motor independently. With such a construction, the fixing to one of these areas in the winding position can serve as a holding device that fixes this winding shaft in a machine-fixed manner. A separate holding device can thus advantageously be omitted. The optional fixation on the inner or outer area allows a large variability of independent movements of the individual winding shafts. This can be increased further in that the inner and / or outer regions are additionally designed to be drivable independently of one another. The already described advantages of one-sided mounting of the winding shafts in a guide drum consisting of two areas naturally occur additively here.

When the winding shafts are supported on both sides in guide drums, it is no longer possible to pull the completely wound rolls off the winding shafts. For this Basically, the winding shafts are expediently releasably connected to the sliding bearings from both sides, so that the rollers can be removed together with the winding shafts or corresponding areas of the winding shafts. Axles which are axially displaceable and can be displaced in axial engagement with the winding shafts are particularly suitable for this purpose, at least the sleeve on the drive side forming a rotationally fixed connection. By retracting the quill, the wound winding shaft can preferably be removed in a simple manner in a lower position.

The holding device which fixes the axis of rotation of the winding shaft in the winding position can preferably consist of a bearing device which can be moved at the end against the rotating end of the winding shaft and, if required, additionally from a machine-fixed holding device for the opposite end. With the holding device actuated and the locking devices released, the drum or the drums can rotate independently of the fixed position and can move other winding shafts. As already stated, such a holding device can also be dispensed with if the winding shafts are supported on both sides and the guide drums consist of two areas.

To guide the sliding bearings along the guide drum, these sliding bearings are provided with guide rollers which roll on the guide drum or the guide drums. Each sliding bearing is preferably provided with at least 8 guide rollers, each in pairs grasp the guideway on the guide drum or support it in pairs on parallel guideways.

Friction brakes or locking elements which engage in structured braking surfaces are suitable as locking devices.

Embodiments of the invention are shown in the drawing and explained in more detail in the following description. Show it:

• 1 is a perspective view of a first exemplary embodiment of a reeling or unwinding device with winding shafts mounted on one side,
• 2 shows the embodiment shown in FIG. 1 in a side view, partly as a sectional view,
• 3 shows the same embodiment in an end view,

• 6 shows a further exemplary embodiment of a device with winding shafts mounted on two sides in a side view partially shown in section, two-part guide drums being used.

In the exemplary embodiments shown, only the actual winding part of such a machine is shown for the sake of simplicity, while the supply of the strip-like or web-shaped material to be wound via guide rollers and required longitudinal and cross-cutting devices or knock-off devices are not shown for simplification. The feed and the cutting devices are of course necessary in any case for a complete unwinding or reeling machine and are described in more detail, for example, in the prior art specified at the beginning. Furthermore, practically all machines on the market have such devices, so that a detailed description can be dispensed with here.

In the first exemplary embodiment shown in FIGS. 1 to 3, a machine frame 10 consists of a drive side 11, a bearing side 12 arranged parallel thereto, and a connecting part 13 between the drive side 11 and the bearing side 12. Further areas required for the stability of the machine frame 10, such as a support part are not shown for simplification.

On the left side of the interior of the machine frame 10 in the illustration, a guide drum 14 is drivingly connected to a hollow shaft 15, which extends outward from the guide drum 14 through the drive side 11. On the outside it will driven by a drive motor 16. The guide drum 14 has a double T-profile on average, the outer, curved profile surface 17 forming a guide track. In the exemplary embodiment, this guideway is circular, but it can also be oval or a polygon with rounded corners for special purposes.

On the outer profile surface 17 of the guide drum 14 three (according to FIG. 3) sliding bearings 18 are freely displaceably supported by guide rollers 19. These are eight of these guide rollers 19, each of which enclose the profile surface 17 in pairs in the region of the outer edges thereof. At both longitudinal ends of the sliding bearing 18 holding plates 20 are attached, which carry the guide rollers 19. Since these holding plates 20 overlap the profile surface 17, the sliding bearings 18 are thereby fixed in the axial direction. To reduce friction, the contact paths between the holding plates 20 and the profile surface 17 can also be provided with rollers in a manner not shown.

From the inner ends of the holding plates 20 as seen in the radial direction, angular locking devices 21 extend to the inside of the profile surface 17. There they are provided with a friction lining 22 which is pressed against the inside of the profile surface 17 when the locking devices 21 are actuated, so that the respective sliding bearing 18 is fixed to the guide drum 14.

In a modification of the arrangement shown, the guide rollers can for example also be supported in pairs on the parallel inner sides of the guide drum 14. The locking devices can in principle also act on another surface of the guide drum 14 which acts as a friction surface. The actuation can take place pneumatically, for example, or via eccentrics.

Winding shafts 23 are rotatably mounted in the sliding bearings 18 and can be set in rotation by drive motors 24 flanged to the outside on the sliding bearings 18.

Winding sleeves 25 can be pushed onto these winding shafts 23 from the free end, onto which the material to be wound can be wound and laterally pushed out together with the respective winding sleeve as a finished roll.

A drive shaft 26 runs through the hollow shaft 15 and is mounted in a bearing 27 at the end on the bearing side. It is driven from the outside of the drive side 11 by a drive motor 28. In this drive shaft 26, two guide grippers 29 are adjustably mounted radially to the axis of rotation of the drive shaft 26. The adjustment can for example not in Darge form pneumatically or via servomotors. The outer ends of these guide grippers 29 are designed as half bearings 30 and can accordingly encompass the winding shaft 23 on one side, on both sides of the winding tube 25 positioned on it.

On the bearing side 12, a guide segment 31 is pivotally mounted about a stopping point 32. This guide segment 31 is essentially designed as a 1/4 circle segment which has a curvature corresponding to the guide path of the winding shaft around the guide drum 14 and can be determined parallel to this guide path. The free end of a winding shaft 23 can be brought into abutment against this guide segment 31 by means of the guide gripper 29 arranged at the corresponding point, so that it represents a counter bearing and the winding shaft can be guided along this guide segment 31.

To fix one of the winding shafts 23 in a winding position, a holding device 33 is provided, which has a bearing device 34 designed as a tip bearing that can be moved against the free, rotating end of the winding shaft. At the opposite, drive-side location, a holding device (not shown or not shown in the drawing) for the drive motor 16 or the sliding bearing 18 of the winding tube 25 in the winding position is provided. In this way, a winding tube can be stored on both sides in the winding position independently of the guide drum 14.

This winding position is seen from the bearing side 12 in the horizontal plane of the drive shaft 26 to the right of the latter, while the removal position is located vertically below this drive shaft 26.

The web or band-shaped material 35 to be rolled up is located in a manner not shown on a supply roll and is fed to a motor-driven winding shaft which is in the winding position via guide rollers 36, only one of which is shown schematically in FIG. 4. It is essential here that the guide rollers are arranged close to one another or the last guide roller 36 is arranged close to the winding shaft in the winding position in order to avoid free web lengths. From a certain roll diameter of the resulting roll, this winding shaft is gripped by the guide grippers 29, the holding device 33 is released and the further rotating winding shaft moves downward along the guide path, so that there is no collision between the enlarging roll and the guide roller 36. The free path length can always be kept to a minimum.

The web-shaped material 35 is divided into three individual webs in the region of the guide rollers 36 by a longitudinal cutting device, so that three rolls are produced from one web. Such a longitudinal cutting device is described in the prior art specified at the outset. Of course, such a subdivision can also be divided into remain or another longitudinal division.

To the same extent as the winding shaft with the enlarging roller moves away from the winding position with the aid of the guide grippers 29, the subsequent winding shaft is pushed into the winding position by actuating its locking devices 21 and by rotating the guide drum 14. If it reaches this, it is gripped by the holding device 33, and the locking devices 21 can be released again. This winding shaft is now accelerated to the required winding speed with the aid of its drive motor 24.

When the desired roll diameter has been reached on the first winding shaft, the fed web is cut off with the aid of a cross-cutting device or a knock-off device and the new web thus formed is wound onto the pushed-on second winding shaft 23 in the winding position without interrupting the winding process. While this winding process is taking place, the winding shaft provided with the finished roll is brought into the removal position with the aid of the guide grippers 29. The guide segment 31 is pivoted, and the finished roll can be pulled off the winding shaft laterally through a corresponding recess 37 in the bearing side 12.

The guide segment 31 can now pivot back into its original position, the guide grippers 29 retracted and pivoted back to the winding position. The winding shaft 23 is fixed to the guide drum 14 by actuating its locking devices 21 and pivoted by rotation of the latter into a new position to the left of the drive shaft 26, where a new winding tube or new winding tubes 25 are pushed on.

This process continues continuously, the number of winding shafts 23 arranged on the guide drum 14 also being able to vary. Their minimum number is two, and their maximum number can also be greater than three. The smaller the rolls to be wound, the greater the number of winding shafts should be. If necessary, they can be removed or additionally mounted.

Of course, the drive motors for the winding shafts are switched off each time a winding process has ended.

4 shows a further exemplary embodiment for a guide drum 40. It consists of an inner region 41, which can be constructed, for example, according to the guide drum 14 already described. An outer annular region 42 is placed around this inner region 41 at a distance d. Guide rollers 43 are supported on the inner surface of the outer region 42 and on the outer surface of the inner region 41 by three sliding bearings 44, in which the winding shafts 23 are rotatably mounted. Eight guide rollers 43 are in turn arranged on each sliding bearing 44, as can be seen in connection with FIG. 6. By arranging at least three such sliding bearings 44, the outer region 42 is centered relative to the inner region 41. Holding plates 45 covering the two regions 41, 42 are in turn provided on both sides of the guide drum 41. Locking devices 46 are arranged between these and the inner area 41, while locking devices 47 are located between the holding plates 45 and the outer area 42. The locking devices can in turn be designed as eccentrics, for example, which are provided with a friction lining or act on such. The actuation can be pneumatic, and it is also possible to slide a friction lining directly onto a friction surface. Finally, the locking devices can also act as latching elements, which act on a structured, in particular toothed braking surface.

The guide drum 40 can be used instead of the guide drum 14, with either the inner region 41 or the outer region 42 being rigidly connected to the drive side 11 for positioning, while the other region is being driven. The inner area 41 can be driven according to FIG. 2, while the outer area can be driven according to FIG. 6 and will be described in more detail in connection with this figure.

If the locking device cooperating with the fixed area is actuated, then the associated sliding bearing 44 is fixed in a machine-fixed manner, while when the other locking device is actuated, a displacement of the sliding bearing together with the rotating area is possible. In this way, a machine-fixed fixation is possible, so that, for example, the holding device 33 need only consist of the bearing device 34 at the free end of the winding shaft.

It is of course also possible to drive both areas 41, 42 independently of one another, so that an even greater variation of the movements is possible.

In the embodiment shown in Fig. 5, the winding shafts 23 are supported at both ends in sliding bearings 18 so that the guide segment 31 and the guide gripper 29 can be omitted. The holding device 33 for fixing a winding shaft in the winding position is still required, but cannot be seen in the perspective view. Otherwise, the same or equivalent components are provided with the same reference numerals and are not described again.

The rotary movement of the hollow shaft 15 driving the left guide drum 14, which can now also be designed as a solid shaft, is parallel to the axis of rotation of the guide via a bearing mounted in the drive side 11 and the bearing side 12 drum 40 extending coupling shaft 50 transmitted to a drive shaft 51 which is mounted in the bearing side 12 and extends from there to the right guide drum 14. In this way, the space freed up can be used for other purposes by eliminating a connecting shaft between the guide drums 14. The coupling between the drive shafts 15 and 51 to the coupling shaft 50 takes place in the illustrated embodiment via two gears 52, of which only the gear 52 arranged on the outside of the bearing side 12 can be seen. Instead of a transmission, a belt or other drive can of course also be provided.

Of course, a continuous drive shaft can also be provided for both guide drums 14, in which case the coupling shaft 50 and the gears 52 can be omitted.

Since it is no longer possible to remove the wound rolls from the side as a result of the double-sided mounting of the winding shafts 23, removal takes place from the lower position downwards. For this purpose, an area 53 of the winding shafts 23 carrying the rolled-up material 35 is designed to be detachable and replaceable. For this purpose, axially displaceable sleeves 54 serve from the sliding bearings arranged on both sides. To remove the area 53 with the rolled-up material 35, the two sleeves 54 are retracted in the direction of the associated sliding bearings 18, so that the area 53 of the winding shaft 23 becomes free and can be removed downwards. To insert a new area 53, the two quills 54 are moved against each other again until the area 53 is fixed. It should be noted here that the left sleeve 54 on the drive side naturally creates a rotationally fixed connection with the area 53. As an alternative to the described mode of operation, the two guide drums 14 can also be driven independently of one another, so that a greater variability of the movements is possible. It is also possible to fix one of the two guide drums in a machine-fixed manner. Finally, the drive via the coupling shaft 50 can also take place directly via friction or gear wheels on the outer profile surface of the guide drums 14.

In the further exemplary embodiment shown in FIG. 6, identical or corresponding components are again provided with the same reference symbols and are not described again. The winding shafts 23 are in turn supported here on both sides, but now on guide drums 40, as shown in FIG. 4. The left guide drum 40 is shown in section and the right, identical guide roller 40 is shown in a side view. The two inner regions 41 are driven synchronously via a central, continuous drive shaft 60 which is driven by the drive motor 16 on the drive side 11. A second drive shaft 61, which runs parallel to the drive shaft 60 outside the guide drums 40, is likewise mounted in the drive side 11 and bearing side 12 and is driven on the drive side 11 by a drive motor 62. The transmission of the movement of the drive shaft 61 to the two outer regions 42 of the guide drums 40 takes place via gearwheels 63, which engage in peripheral gear rings 64 of the outer regions 42. Instead of a gear drive, a friction wheel drive, a chain drive, a belt drive or the like can in principle also be used. be provided.

The two drive motors 16, 62 should be designed to be self-locking, that is, when the respective motor is at a standstill, the associated drive shaft is fixed in the respective position.

In the embodiment shown in FIG. 6, a separate holding device 33 for fixing one of the winding shafts 23 in the winding position can be omitted, the fixing of the winding shaft 23 in question in the winding position now serving as a holding device via the locking devices. A winding shaft can namely be fixed to one of the areas 41, 42 and moved to the winding position, the relevant drive motor then being stopped. This causes a fixation in the winding position. When the reel becomes larger, this winding shaft can then be moved further with the same motor, while the subsequent winding shaft, which is fixed to the other area, with the other drive motor is moved into the winding position. The finished material rolls are removed in accordance with the exemplary embodiment shown in FIG. 5.

In a simpler embodiment, either the inner region 41 or the outer region 42 can also be fixed in a machine-fixed manner. Although this leads to a certain restriction of the movement possibilities, in principle a similar movement sequence can be achieved. Furthermore, it is also possible to drive corresponding areas of the two guide drums 40 independently of one another. This leads to an expansion of the range of motion.

Of course, the drive options, locking options and storage options described in the various exemplary embodiments can also be combined with one another without deviating from the basic inventive idea.

Finally, it is also possible to use the arrangements described not only for rolling up, but also for rolling off. The movements shown are basically reversible in their direction, so that e.g. a roll to be unwound is inserted in the removal position, then transferred into the winding position, which now serves as the unwinding position, the empty winding tube then being able to be removed after unwinding after a further displacement of the winding shaft.
