Abstract

The winding system for a paper slitter-rewinder can simultaneously wind several reels in different positions. A winding bar (11) is provided for each reel (9). The bar can be moved away from it and its height above reel support rollers (2, 3 ) can be varied. A feeder (22) fits cores (10) on the winding bar and removes completed reels from it.

Description

The invention relates to a roll winding device, especially for a slitter winder, for simultaneous winding of several winding rolls with one winding position for each winding roll, whereby several winding positions in the axial direction one behind the other are arranged, and with a backup roller arrangement below the winding positions.

The invention is described below using the example of paper webs described, which wound up into paper web rolls should be. However, the invention is also in other material web applicable in longer lengths are produced and therefore wound into winding rolls become.

Paper webs are usually made with larger widths manufactured when later used by a user, for example a print shop, can be used. Therefore, in one of the last manufacturing steps cut the wide paper mat lengthways and the resulting partial webs become too Winding rolls wound up. It is obvious, that these winding rolls are wound as similar as possible must, because also the supplied partial webs with arrive at the same feed rate.

Many are used as the core for the winding roll Cases winding cores or winding cores that act as tubes are formed, preferably from a cardboard box. The Sheets are attached to the winding tubes. The winding sleeves then turn and pull the web yourself. To prevent the winding tube from bending, the winding rolls are created from below by one Support roller arrangement supported. The backup roller assembly can have, for example, two support rollers, which together form a changing bed. It can but also be a single backup roller on which the winding rollers in the area of their upper half in contact being held. Finally, the backup roller assembly also be formed by a contact roller, on which the winding rollers only rest without them by weight. The backup roller assembly can also have other support elements, such as a circulating belt on which the winding rolls rest.

In all cases, you have to perform several tasks. To the one would like a certain winding hardness curve to reach. The winding rolls should be in the area of the roll core, i.e. the winding tube, a greater winding hardness have as on their outer edge, i.e. the winding hardness should decrease from the inside out. Furthermore you have to make sure that the winding rolls in system stay on the backup roller assembly, for example a jumping out of the winding rolls from the winding bed prevent.

After all, you want the winding of the winding rolls runs as quickly as possible, i.e. you want to set up or Keep dead times short between finishing a set of winding rolls and starting a new one Set of winding rolls is created. Here is a factor that the winding tubes according to the pattern Position correctly one behind the other in the axial direction and spend them in the right wrap positions got to.

The invention has for its object the handling to simplify when winding.

This task is done with a roll winding device of the type mentioned in that a by a predetermined number of winding positions continuous winding rod is provided outside the winding rollers in relation to the backup roller assembly adjustable in height is held in a stand arrangement and that a winding bar feeder is provided the winding tubes on the winding rod or Removes winding rolls from the winding bar.

With this training you can achieve a number of advantages. The winding rod initially has a holding function. With it, it is possible for the individual Winding rolls in contact with the support roller arrangement hold and a jumping out of the winding rolls from the To prevent changing bed. This is also possible when the individual winding rollers are practical in the axial direction connect to each other so that not enough Space is available to hold one for each winding roll to use your own winding head for holding. With help the winding rod can now also have a certain contact pressure the winding rollers on the backup roller assembly achieve so that you have some influence on the The hardness of the winding rolls can take, among other things from Niplast in a support or contact nip between the winding rollers and the backup roller assembly depends. In addition, the winding result can also improve. The individual winding rolls are on the Winding rod guided and turn everyone accordingly the same center. So you get a concentric Roller run in the changing bed. Non-circular roll cross-sections and an accompanying discontinuous course the winding hardness over the roll cross section of a Roll sets can thus be avoided. The result is a very low vibration, quiet winding and round winding rolls. Should there be thickness profile deviations surrender, then these will be wound up with everyone individual layer by wrapping more or less Air balanced immediately. This leads to comparisons with conventional carrier roller machines Winding hardness curve across the cross-section of the winding rolls essential for all roles of a role set is more even, especially when one uses a load roller because the nip forces also much more even on the load roller are. In addition, there will be differences in roll diameters, if at all, only in a very small one Set order of magnitude. Another advantage is that that the handling of the winding tubes is now essential is easier. You will, in turn, if necessary with the interposition of spacers, threaded onto the winding bar and are then in the correct winding position arranged both in the axial direction as well as in the radial direction. Possibly you can also make sure that the winding rod loaded outside of the actual winding position is, these equipments with winding cores during the winding of a previous roll set. This in turn saves time and enables a relative accurate work because of disturbances caused by the winding operation largely avoided.

Preferably, the backup roller assembly has for each Winding position at least one roller with an elastic Surface on. As stated above, smaller ones Thickness profile deviations even in modern paper machines cannot be completely excluded. This but are relatively small. If you have at least one elastic surface on a roller of the support roller arrangement used, then due to thickness profile deviations conditioned diameter deviations relative can be balanced easily.

The winding rod is preferably driven. In order to there is an additional parameter for influencing of winding hardness available. One can namely an additional one Introduce drive torque into each winding roll so that you are in the extreme positions of the winding roll can generate a predetermined web tension, which is "wrapped up". Centric driving of Winding rolls is known per se, but only then, if you have each winding roll with its own winding head or a pair of winding heads. This possibility So far there have not been any winding rolls with little or no axial spacing wraps one after the other, as it does for example with one Double carrier roller winder is the case.

The winding rod preferably has an activatable one Clamping device on. The activated tensioning device holds the winding rolls. If you look at the tensioner deactivated or released again, you can Winding rolls and the winding bar slightly apart separate. With this, if the winding rod is driven is much better defined drive conditions than when you create the winding cores only axially onto the winding rod under friction postpones. Above all, however, it is advantageous that the loading and discharge processes much faster and run more smoothly.

The winding rod is preferably via a coupling releasably held in the stand assembly. In this case it is possible not only to drive the winding bar, but also to take them out of the stand assembly. This enables you to do the same as described above realize using multiple winding bars being wound on a winding bar while the other winding rod for the next winding process is being prepared.

Preferably, the winding bar loading device a bracket that holds the winding bar on one End holds, and one acting parallel to the axis of the winding rod Conveyor arrangement. So the other is axial End of the winding rod free so that you can go from this end can slide out of bobbins or over this end can pull off the finished winding rolls. Because the winding bar but is held at one end, it lies in the Basically firmly, so that you have defined positions for loading or unloading. In in this case, the corresponding operations automate more easily. In addition, this configuration yet another advantage: the winding bar is fixed, so when loading or unloading not moved axially. The loading or unloading takes place rather, in that the individual sleeves one after the other be pushed onto the winding bar. In in the same way, the individual winding rolls are unloaded subtracted from the winding bar. With that is in Axial direction only one space is required, the length the winding rod plus the length of the largest, i.e. widest, Corresponds to the winding roll. Of course you get additional provide a certain handling space have to. Would you pull out the winding rod would require a space that is at least the corresponds to twice the length of the winding rod.

Preferably, the winding bar loading device at least one extendable support stamp on in the axial direction at a predetermined distance is arranged from the bracket. In particular with longer winding rods there is a risk that the winding rod bends under its own weight and the end leaves an area where there is still an automatic List of winding cores would be possible. If you now provide an extended support stamp, then this support stamp of the deflection or acts other lowering of the winding rod counter.

It is preferred that the support stamp as a support has a roll for the winding rod. So that's it possible, the individual winding tubes even then on the Slide the winding bar when the winding bar is open the support stamps. The winding tube then lifts the winding rod briefly from the roll. Another Movement of the winding tube is possible without any problems, because the winding tube then along the roll can roll.

In a particularly preferred embodiment, that the support stamp by a predetermined amount is retractable when the conveyor is a winding sleeve promotes on the winding bar. This configuration is particularly advantageous if you have at least has two support stamps. That holds a support stamp then the winding bar in the desired orientation. The other support stamp is when the winding tube passes pulled back briefly, basically it taken is only necessary to overcome the stage, that arises at the end of the winding tube. If the end face of the winding tube the support stamp happened, then the support stamp can be raised again to the winding rod then with interposition to support the winding tube. Even in the end the winding tube, it may be advantageous to use the support stamp lower briefly in order to make a sudden load to avoid the winding rod. In many In cases it is sufficient if the drive back is "passive" done, the support stamp against the force of one Spring is pressed down. This spring enables also the lifting movement when the winding tube is the support stamp happened.

The predetermined dimension preferably corresponds to this a wall thickness of the winding tube. That way it ensures one for the fact that even in the retracted state of the Support stamp the desired support of the winding rod preserved.

It is also advantageous if the support stamp with a Control device is connected, which drives him back.

In this case, the control device only has to be connected to the conveyor, the conveyor information about the axial length the winding tube has to position them anyway to be able to. Here, the end face of the winding sleeve less burdened.

Advantageously, the conveyor points back and forth outgoing driver, each of a winding tube promotes from a supply position on the winding rod. Accordingly, the conveyor does not necessarily have to Movable over the entire length of the winding bar his. Rather, it is sufficient if it is able to to push one winding tube onto the winding rod. This sleeve can then the rest, already on the Push the winding tube located on the winding tube. But it is also possible that the driver actually covers the entire axial length of the winding bar, to be able to position each winding tube individually. By using a driver that goes now and then the winding sleeves can be moved individually handle, which significantly simplifies loading.

The stock position is preferably on a sleeve table educated. So you can use the winding tubes Place them one after the other on the sleeve table. Each in The sleeve located in the stock position is placed on the winding rod pushed. By simply re-feeding of the individual winding tubes on the tube table in the Stock position can then be achieved that the individual Winding tubes one after the other onto the winding rod be postponed.

It is preferred that the sleeve table is inclined and has a stop. The stop is arranged that a winding tube resting at the stop automatically is in the stock position. Then if this The winding tube has been pushed onto the winding rod, the next winding tube slips or rolls, so that it is in the stock position. If you like said the individual winding cores in the order lying side by side, as they would later in a row (seen in the axial direction) arranged on the winding rod should be the right one Distribution.

Preferably, the sleeve table and possibly the Driver from a loading position to a rest position relocatable. So the sleeve table is just then moved to the loading position when actually the winding rod is loaded should. If he has been put in the resting position, then you can run other processes in the same place to let.

Preferably, the winding bar loading device a winding roll transport device on the Pulls out the winding rollers from the winding bar. If the Winding rolls have been completely wound, then located them on the winding bar. The winding bar is then held at one axial end and the Winding rolls are individually or together from the winding rod deducted. This may be a existing engagement between the winding rod and the Winding rollers lifted so that the winding rollers face each other the winding rod can move freely axially. It the winding roll transport device is then sufficient to put into operation, the winding rollers in the axial direction the winding rod is removed. This will the winding bar free.

It is preferred that the winding roll transport device has a first part and a second part, the two parts being controllable separately. With this configuration, it is possible for the individual To separate winding rolls of a roll set or roll throw. Both parts of the winding roll transport device are operated together until the first role of the first part on the second part of the winding roll transport device has arrived. Then the first one Part are shut down and the second part promotes the winding roll. Then if a predetermined distance reached between the first and the second winding roll the first part can be in operation again be taken to the second winding roll from the winding rod deduct. This process can be repeated until all the winding rolls are pulled off the winding bar and the desired distance from each other exhibit. You don't necessarily have to do the first part stop. You can also do both parts with different Let speeds work. In this Case, however, there is a risk that between the Surface of the winding rolls and at least one of the two parts of the winding roll transport device Slip arises, which negatively affects the outer layers the winding rollers can impact.

The second part preferably has a length that the longest expected winding roll plus a predetermined one Distance dimension between winding rolls corresponds. With such training you can Keep the winding roll transport device relatively short.

So you must the entire axial length of the roll winding device only exceed by the stated amount.

The winding roll transport device preferably has in the direction of gravity below one of the Bracket in the direction of the longitudinal extension of the winding bar extending line at least one opening, through which a support element is movable. The following applies here Basically the same as when loading with winding cores. With longer axial lengths, the winding rod tilts to bend. If you look at the winding roll transport device trained so that at certain Make openings through which you can drive support elements, then the winding rod also largely supported during unloading. The At least in the first nourishment, winding rolls have all that same diameter. If the winding rollers in the axial direction be pulled off, then the winding rod through a large part of the removal process supports the winding rolls themselves. As soon as one if the free length is too large, you can walk past it extend the support element of the last roll, to support the winding bar. Until then it works the winding roll itself as a support.

The loading position of the conveyor is preferably above the winding roll transport device arranged. You can then use the winding bar in loading and unloading in the same position hold and support in the same way with support stamps, which further simplifies handling.

A rolling surface between the Back-up roller arrangement and the winding roll transport device arranged. When the winding rolls are completely wound they are usually so heavy, that they only raised with a relatively high effort can be. If you look at the rolling surface between the support roller arrangement and the winding roll transport device then you can use the winding rolls together to the winding roll transport device let it roll. All winding rolls are in the axial direction still connected to each other via the winding rod, see above that the effort required to "catch" the winding rolls needed, can be kept small.

A transport arrangement with a Gripping head provided by the winding bar feeder movable to support roller arrangement is. The transport arrangement therefore takes over the transport the winding rod loaded with the winding tubes from the winding bar feeder to the backup roller assembly. It can be used to transport a automate completely prepared set of winding cores, i.e. there are no more manual interventions necessary. This arrangement therefore also holds the risk of accidents small.

The transport arrangement is preferably a transport arm trained, the pivotable and adjustable in length is trained. By swiveling cover a predetermined path relatively quickly. With the adjustable length of the transport arm can you have a relatively accurate positioning of the winding rod to reach.

A winding bar magazine is advantageous in the range of motion the gripping head arranged. The circular head cares then not just for transporting the loaded one Winding bar from the winding bar feeder to the support roller arrangement, it can also go a loaded or not loaded winding bar in the Deliver the winding bar magazine and another winding bar to fetch. This is advantageous, for example, if winding rods with different diameters or with different lengths are required.

The advantage here is that the winding rod magazine with several storage locations and possibly as a revolver magazine is trained. The revolver magazine has a rotatable plate or a rotatable Cylinder on which the possible stock positions for the winding bars on a circular line around the center of rotation are arranged. The individual storage locations can thus optionally in a transfer position be moved. This simplifies the control of the Gripping head.

The winding bar magazine is preferably above the Roll out surface arranged, the distance between Roll-out area and winding bar magazine is larger than the diameter of the largest winding roll plus the diameter the largest winding tube. In this case you can at the same time a loaded winding bar from the winding bar loading device for back-up roller arrangement transport and the winding rolls over the rolling surface roll to the winding roll conveyor to let. This keeps the set-up times short. You can go faster again with the start of a new set of Start winding rolls.

A roller winding device 1 has in the embodiment 1 and 2 two support rollers 2, 3 on together form a changing bed 4. The support rollers 2, 3 are rotatably mounted in stands 5, 6 and each have a drive 7, 8. Lie in the changing bed 4 when winding several winding rolls 9 so that their axes of rotation lie on a line. Every winding roll 9 has a winding tube 10, for example a cardboard tube. All winding tubes 10 are in one Winding rod 11 fixed, i.e. rotatable with the Winding rod 11 connected. The winding rod 11 can expansion organs not shown for this purpose have, for example, with compressed air from the inside can be tensioned against the winding tubes 10. If these expansion organs are relaxed, then let the winding tubes 10 are opposite the winding rod 11 move, i.e. rotate and move axially.

The winding tubes 11 each have an axial length, which corresponds to the axial length of the winding rolls 9, thus the width of the material web to be wound up. Shown is a situation where all winding rolls 9 the have the same width. However, this is not mandatory required. You can also use winding rolls 9 with of different widths. The winding rolls 9 lie with a predetermined distance 12 in the changing bed. To ensure this distance, one can if necessary 10 spacers between the winding tubes 13 on the winding rod 11 or arrange the winding tubes 10 with a small oversize based on the roll width cut to length.

The winding rod 11 is on each clutch 14 Side connected to a drive 15 in the stand 5, 6. By moving in the direction of a double arrow 16 the clutch 14 can be engaged or disengaged, so that the winding rod comes free from the drives 15 or can be connected to them in a rotationally fixed manner.

The drives 15 are with their couplings 14 in the Stands 5, 6 arranged height adjustable, what by a double arrow 17 is symbolized in Fig. 2. In order to can the distance of the winding rod 11 from the changing bed 4 change, so that one increases the winding Take the diameter of the winding rolls 9 into account can.

Above the winding rollers 9 there is a pressure roller 18 provided that is also adjustable in height in the stand 5, 6 is arranged, which is indicated by a double arrow 19 is shown. The pressure roller 18 can also Have 20 drive.

The winding rod 11 with the winding sleeves is now used for winding 10 provided. This can be done inside the changing bed 4 done. As you can see below, this winding rod 11 is preferably loaded outside the changing bed 4. The changing rod 11 is then coupled to the drives 15. The powered Winding rod 11 causes in the winding tubes 10 by winding the center drive of the winding rollers 9 a relatively hard core. Depending on size the winding rod, it is now possible to significantly larger Initiate drive power via the winding bar, than that with center drive machines today and clamping heads is sometimes possible. Additional drive torque can over the pressure roller 18 and / or two support rollers 2, 3 are initiated.

If the winding rod 11 is not driven, then she still has two jobs. On the one hand, it serves to guide the roles and thus to prevent a accidental ejection or reel kick-outs. Possibly it is also conceivable that you can use the winding rod 11 a roller load at the beginning of the winding process and a role relief after reaching one predetermined diameter of the winding rolls 9, so that the loading roller 18 under certain circumstances becomes dispensable.

At least one of the two support rollers 2, 3 is with one elastic or soft surface. Such a soft coating 21 has the advantage that deviations in the transverse profile of the material web to be wound, which are usually smaller than 1 µm, easily balanced and the pressure forces in the support ip can be minimized.

Carrier roller machines of this type that do not have a winding rod work, have the problem of diameter deviations of the individual winding rolls 9. Accordingly, the axially continuous load roller 18 normally unable to track the paper thickness profile deviations completely compensate. That means, that differ greatly on the loading roller 18 Adjust nip forces, causing an uneasy Changing in a changing bed due to eccentric Roller run, and thus leads to non-circular roles. The Winding hardness curve over the roll cross section of a This makes disc sets discontinuous. If there are differences in the roller knives of a set, leads this leads to speed differences and slip between the support rollers, the winding rollers 9 and the loading roller 18th

This is avoided with the winding rod 11. The winding rolls 9 and their winding tubes 10 no longer run eccentric, but are fixed by the winding rod 11 and led. All winding rollers 9 rotate around that same center, which is a concentric roller run in the Has a changing bed. The result is a very low-vibration, quiet winding and comparatively round rolls. Which may also apply to modern Paper machines still existing, but very small Paper thickness profile deviations become apparent with the winding every single layer by wrapping more or less air in the winding roll 9 immediately in each Level of paper balanced. This leads to - compared with known results - the winding hardness curve across the cross-section of the winding rolls for all rolls of a roller set is much more uniform because the Nip forces on the load roller 18 are also essential are more constant. There will also be differences in diameter the winding roll 9, if at all in minimal Set order of magnitude. These diameter deviations are by the elastic coverings 21 of Carrier and load rollers 2, 3, 18 balanced.

3 shows a somewhat modified embodiment, at the same elements with the same reference numerals are provided. Instead of two support rollers 2, 3 in this embodiment, a backup roller assembly used, which is formed only from a support roller 2. This support roller 2 also has an elastic covering 21 on. Since the winding rollers 9 are held on the winding rod 11 support from a support roller is sufficient 2 out.

Fig. 4 now shows the roll winding device 1 together with a winding bar feeder 22 which it allows the handling of the winding rolls 9 and their To simplify winding sleeves 10 quite considerably. Under "Feeding" should not only be the process of Loading or performing winding sleeves 10 on the Winding rod 11 are understood, but also that Unloading or pulling off completely wound winding rolls 9 from the winding bar.

4 shows an exemplary embodiment of FIG which can be deviated in many ways without to change the basic principle.

4 is in the left half of the partial views the winding device 1 shown as they are 2, but not in all partial views the winding roll 9 is shown. In addition to an ejector 23 is shown on the left support roller 2, which serves to remove the winding rolls from the winding bed 4 to press or hit a rolling surface 24, which is slightly inclined to one by the backup roller assembly Winding roll transport device 25 extends. There a roller catcher 26 is provided. The winding roll transport device 25 has two conveyor belts 27, 28 on, the V-shaped with a relatively large opening angle are inclined relative to each other and a gap leave between yourself in the one or more Support stamp 29 are arranged in the direction of a Double arrow 30 can be extended and retracted, such as a comparison of FIGS. 4a, 4b shows.

Above the rolling surface 24 is a winding bar magazine 31 arranged, the multiple storage locations 32 for Has winding rods 11. The winding bars 11 can different diameters or different have axial lengths. The winding bar magazine 31 is designed as a revolver magazine, i.e. it points a round plate or a short cylinder on the with the help of a drive 33 in the direction of the double arrow 34 can be rotated. The winding rod 11, the is in the lowest position, can from the Winding rod magazine 31 can be removed or a storage space, which is in the lowest position of the winding rod magazine 31 is located with a winding bar 11 are occupied. Only the is shown Plate on the stand 5. Especially when the roll winding device 1 is longer, but it is sensible, the roller bar magazine 31 with a corresponding Bearing plate on the opposite stand 6 equip. The definition of the winding rods 11 in Winding rod magazine 31 can then take place, for example, that axially movable bolt from both sides forth into the end faces of the respective winding rod 11 are inserted.

A swivel arm is located below the winding bar magazine 31 35 arranged around a pivot point 36 in the direction a double arrow 37 is pivotable. The Pivot 36 is approximately at the level of the roll-out surface 24 arranged. In addition, the swivel arm is 35 in Direction of a double arrow 38 extendable and retractable, therefore variable in length. At the free end, the Swivel arm 35 has a gripping head 39 which is capable of is to detect a winding rod 11. The swivel arm 35 is arranged outside the rolling surface 24, i.e. as a rule, also outside of the axial extension the support rollers 2, 3. It is obvious that such a swivel arm 35 also in the area of Stand 6 is arranged so that the winding rod 11th be gripped in the area of their two axial ends can.

4a, the swivel arm 35 is now pivoted and extended that the gripping head 39 in the lowest Position of the winding rod magazine 31 located winding rod 11 can take. The swivel arm 35 will then retracted and, based on Fig. 4a, clockwise pivoted until the winding rod 11, as in Fig. 4b is shown, above the winding roll transport device 25 stored in a performance position is in the winding tubes 10 on the winding rod can be postponed. In this position the Gripping head 39 the winding rod 11 free.

This performance position is intended to be explained in more detail with reference to FIGS are explained. As can be seen from FIG. 6, the winding rod 11 is one-sided, i.e. only on the left End (based on Fig. 6) held in one Bracket 40. Bracket 40 not only fixes that End of winding rod 11 but is also able absorb a certain torque load, so that the winding rod 11 from the bracket 40 substantially protrudes horizontally. On the bracket 40 is a Spacer 41 attached, within certain limits is adjustable.

With longer winding rods 11, however, the bracket would be Overwhelmed. The situation could also arise that the winding rod 11 bends. For this Reason are at predetermined intervals from the bracket 40, the support stamp 29 already mentioned above arranged, at the upper end of each a roller 42nd is arranged as a support surface. The support stamp 29 are extended so far that they the winding rod 11th support in the direction of gravity.

As can be seen from Fig. 5, a number of Winding tubes 10 held ready on a tube table 43. The sleeve table 43 is slightly inclined and points a stop 44 up to which the winding tubes 10 can roll. If the winding tubes 10 at the stop 44, then they are at the same time in alignment with the winding rod 11. Above the Winding rod 11 is a rodless cylinder 45 arranged with a driver 46 which in the direction of a Double arrow 47 is reciprocable. The driver 46 is therefore able to form a winding tube 10 to slide axially onto the winding rod 11. Once there a winding tube 10a in the area of a support stamp 29 arrives, this is a predetermined Route retracted, this distance being the radial Corresponds to the thickness of the winding tube 10a. This thickness is known and can be set beforehand. The winding tube 10a can then be pushed on and rolls because of the roller 42 on the support stamp 29. there the support function of the support stamp 29 is maintained. This process is repeated until the desired set of winding tubes 10, 10a on the Winding rod 11 has been pushed on. As a result of that the individual winding tubes 10 in the desired Patterns placed side by side on the sleeve table 43 reached one automatically the correct positioning of the individual winding tubes 10 on the winding rod 11, i.e. you can change patterns of winding cores 10 provide on the winding rod 11 without this major problems.

The support stamps 29 can be actively retracted, for example by a pneumatic or hydraulic Engine, for example in the form of a piston-cylinder unit. However, it is also possible to use the support stamp 29 by a spring or spring arrangement, not shown to support so that it is through the incoming Winding sleeve 10a is pressed down. The feather can on a stretch that is the wall thickness of the winding tube 10a corresponds to being set to "softer". On in this way it is possible with simple means that Realize support function and still retract allow. When the winding tube 10a the support stamp 29 has happened, the support stamp is again after pressed at the top.

Fig. 4b now shows the situation in which the winding rod 11 with the desired set of winding tubes 10 is. The gripping head 39 now grips the loaded one Winding rod 11 and pivots by almost 180 ° in the counterclockwise direction, until he has the winding rod 11 with the on it Place the winding sleeves 10 in the winding bed 4 can. The winding rod 11 is then over the clutches 14 connected to the drives 15. In itself in a known manner, the partial webs are now on the winding sleeves 10 listed and if necessary glued and the pressure roller 18 lowered onto the winding tubes 10 and the wrapping process can begin. During the Winding, in which the diameter of the winding rolls continuously enlarged, as shown in Fig. 4d is, the swivel arm 35 from a new winding rod pick up the winding bar magazine 31 and, as in the context with FIGS. 5 and 6 described, with winding tubes let loaded. The winding rolls 9 are now powered by up to four drives, namely the two Drives 7, 8 of the support rollers 2, 3, the drive 15 the winding rod 11 and, if appropriate, the drive 20 the loading roller 18. In addition, the loading roller 18 and the winding rod 11 forces in that Changing bed 4 can be exercised into it. In a later one Stage of winding when the diameter of the winding rolls 9 has become larger, the winding rod 11 however, can be used for relief.

After reaching the desired diameter, the Ejector 23 set in motion and in the direction of Double arrow 48 pivoted. The winding rolls 9 are thereby ejected from the changing bed 4 and over the Roll-out surface 24 to the winding roll transport device 25 rolled where they are stopped by the roller catcher 26. While rolling, the swing arm 35 can be a new one with winding tubes loaded winding rod 11 against the Swivel clockwise into the changing bed 4, what from Fig. 4e can be seen. This means dead times in which the roll winding device 1 cannot wind, kept small. Even if a real continuous Winding process is not yet possible, you can approximate this target very largely.

So that the winding rolls 9 on the winding roll transport device 25 can roll, it is necessary that the sleeve table 43 with the cylinder mounted thereon 45 is moved away. This is a not shown Drive available, the sleeve table 43 for example sideways in the direction of the double arrow 48 can shift.

7 to 9 now represent the situation on the winding roller transport device 25 if the procedural stage is reached, which is shown in Fig. 4f is. The winding rollers 9, which are with their winding tubes 10 are on the winding rod 11, lie as Block on the conveyor belts 27, 28 on. Here are the conveyor belts in a first part 28a and second part 28b divided. Both parts 28a, 28b can be driven separately. Same thing naturally also applies to the other conveyor belt 27, which is divided into two parts 27a, 27b, which are shown in FIGS 7 and 8 are not visible because of the parts 28a, 28b are covered.

The conveyor belt 28a is first driven so that the winding rod 11 is moved to the bracket 40 where it is again set unilaterally. The bracket 40 can be extended in the direction of an arrow 49 for this purpose become. When the winding rod 11 is set it is relaxed, i.e. deactivated. For example can extendable small support stamp 50 or Rubber membrane is relieved and thus retracted. The winding rollers 9 are then from the winding rod 11 solved and can be rotated on the winding rod 11 and especially axially.

The two parts 28a, 28b of the conveyor belt 28 are now set in motion and move the Winding rolls 9, as can be seen from Fig. 8, after right. As soon as all winding rolls 9 have a support stamp 29 have moved away, it is extended, to support the winding rod 11.

As soon as the first winding roll 9 on the second part 28b of the conveyor belt 28, the first part 28a of the conveyor belt stopped. By further transport the first winding roll 9 on the second part 28b the conveyor belt can now be a distance between generate adjacent winding rolls 9. The same situation results when the second winding roll 9 reaches the second part 28b of the conveyor belt 28 is, as can be seen from Fig. 8. The second Part 28b of the conveyor belt 28 can of course also be shorter be if at its end another transport device is available, the winding rolls thus formed transport to other processing stations, for example to a packing station.

The winding rod 11 fixed in the holder 40 can now be loaded again with winding cores 10. It it is also possible that the gripping head 39 in again Action occurs and the winding rod 11 from the illustrated Spends bracket in the winding rod magazine 31 and pick up a new winding bar there.
