Definitions
- Document (1) shows a winding machine with a central support roller and with (two) outer carrier rollers arranged on both sides of the same.
- the three Carrier rollers form two winding beds for winding a plurality of Rolls of paper that are made from longitudinally cut partial webs.
- Role change is carried out as follows:
- a separator is swung into the first changing bed from below. This is done here Cutting the partial web (s) in that the paper roll (s) from the Changing bed is or will be ejected into a drain table.
- the second The paper roll (s) located in the changing bed is or are first placed in a Ejected discharge table, after which one sunk in this discharge table arranged separator is brought into its working position. The Cutting takes place here e.g. by lowering the drain table.
- Document (2) shows and describes a method and a winding machine, which unwinds the paper web from a supply roll and into one Backup roller is guided.
- the backup roller has a perforated roller jacket and is vacuumable.
- the paper web wraps around the support roller on one part of their scope. It is at a certain point in the scope of the Back-up roller wound onto a winding tube to form a paper roll. Is a The roll is completely wound, so it becomes the first one running transversely to the running direction Glue track applied to the paper web. Seen in the running direction a perforation is applied to this glue track, through which the web is weakened, and again, subsequently, another crosswise Traces of glue applied on the paper web.
- the incoming web e.g. by slowing down the supply roll
- the incoming web jerkily slows down and thereby at the Zone of weakness severed.
- the first glue track in the running direction serves the resulting web end to the last layer of the finished roll and the second glue track (seen in the direction of travel) serves to the beginning of the path of the now following path to a new winding tube to stick.
- the web is not in the weakened zone tears off, but in front of it, e.g. in an area where the web is clear of Supports running.
- the subject of the document (3) is one across the entire Web width traversable weakening element during a standstill the machine against the web resting on a support roller in order to to squeeze the web and thereby weaken it. This traverse movement takes a relatively long time. There is also a risk of Damage to the surface of the backup roller. The complete cut is then done by increasing the web tension.
- the document (6) shows a method and a device for changing of winding rolls in machines for winding material webs, especially paper or cardboard webs on cores.
- Winding rolls become double-sided adhesive strips on the web upset.
- the adhesive strips are first placed against the web movable transfer element (transfer roller) with less adhesion than applied the material web, then the transfer element (Transfer roller) moved against the web and the adhesive strips to it to hand over.
- the invention has for its object a method and an apparatus according to the preambles of the independent claims, with what operational safety during the phase of the roll change - despite automatic process as fast as possible - can be increased.
- the finished roll (s) should be behind the glue point have the shortest possible free web end.
- the inventor has recognized that the cause of known in Defects (according to documents 2 or 3) is that the backup roller after cutting the web under the essentially at a standstill new web start continues and at the Paper web grinds. Thereby prevail between the lateral surface of the Backup roller and the web after severing undefined conditions, and the web runs sideways.
- the characterizing part of claim 1 specified method steps or those in the characterizing part of claim 13 specified device features provided.
- the invention can be different in several winding machines Apply type. Among them are winding machines that only one Back-up roller have (see document (2), Fig. 1), as well as winding machines two or three support rollers, which form one or two changing beds in pairs. In the latter case, the weight in the A roll of compressed air is created in the changing bed being constructed. This includes one from below between two Retractable seal assembly required for rollers (claims 16-18).
- the arrangement and design of such a sealing arrangement is - thanks to the method of severing the paper web according to the invention when changing roles - much easier, because the from publication (1) known (and can be inserted from bottom to top between two support rollers) Separating device is no longer required. So far has the necessary Consideration of this separator often creates difficulties.
- Preferred application of the invention are winding machines (with or without longitudinal cutting device), the "off-line", that is isolated from one Papermaking machine operated.
- Machine speed of the winding machine is generally higher than that of the paper making machine. This usually makes it necessary, according to claim 1, the machine speed for the Changing roles (i.e. temporarily) towards a crawling speed to reduce.
- the method according to the invention can have the features of claims 2 to 12 are further developed.
- To further increase the Operational safety during the phase change phase can be done Working speed of the winding machine after reaching the Gradually reduce the creep speed even further (claim 2).
- it is beneficial if you keep the work speed during the ejection of the rollers to zero or almost zero. If however, it is desired that the entire roll change operations be carried out in run for a particularly short time, then you can - as long as the Weakened and the adhesive is applied - the Keep creep speed substantially constant (claim 3). Also during the ejection of the roll (s) you can use the winding machine if necessary, let it run slowly (claim 4).
- the ejection of the roll (s) is preferably first (according to claim 5) then trigger when the adhesive traces have reached the roller (s) so that the intended web end is glued to the roll. It deviates from this however, it is also possible to eject the roll (s) shortly before trigger, so that the sticking of the web end during the ejection process takes place (claim 6).
- Claims 7 and 8 relate to different configurations of the method according to the invention a winding machine with two support rollers.
- Claims 9 and 10 relate to special configurations of the method for a Winding machine with three support rollers. A modification for a machine with only a single support roller is specified in claim 11.
- Claim 12 states that the The weakening point must immediately follow the traces of adhesive. It is it is basically irrelevant whether the application of the adhesive before or after or at the same time as the weakening point is incorporated. However, the adhesive dispenser (with regard to the Arrange web direction) behind the weakening device so that a Contamination of the weakening device with adhesive is avoided.
- Figure 1 shows schematically a slitter with a carrier roll winding machine.
- Figure 2 shows the lateral change in working speed during the role change.
- FIGS 3 to 5 show the timing of the role change in the 1.
- Figures 6 to 8 show the process of changing roles in a Winding machine with three support rollers.
- FIG. 9 shows an alternative to FIG. 5.
- FIG. 10 shows an alternative to FIG. 8.
- FIG. 11 is a top view of the winding machine according to FIG. 10.
- Figure 1 shows i.a. a carrier roller winding machine with two carrier rollers 1 and 2, which form a changing bed 19.
- the support roller 1 has a perforated Roll shell, the interior of which can be connected to a vacuum source.
- a paper web 3 comes e.g. from a unwind station from a supply roll 10, runs among others via guide rollers 13, 14 and is, for example, from below the support roller 1 brought up.
- the web wraps around this roller on one Part of its circumference and is on a winding tube 9 to a paper roll 3.1 wound up (or to several rolls of paper 3.1, if one Longitudinal cutting device 15 is activated). It is also conceivable that the train not from the unwind station but ("online") directly from a Paper making machine is fed.
- a perforating device 4 is shown schematically preferably according to utility model 29508732; its content is hereby a component of the present patent application.
- An adhesive dispenser 5 is Part of a plurality of glue dispensers across the width of the paper web 3 are arranged in a row. 7 with a conveyor belt is designated after changing the supply roll 10 to insert the new one Serves at the beginning of the path.
- the supply roll 10, the support rollers 1 and 2 and for example the guide rollers 13 and 14 are each provided with a drive are.
- Each of these drives is connected to a control line 30 to 34 central drive control unit 20 connected. This ensures that everyone driven rollers constantly at least approximately synchronous, i.e. With a desired path speed, controllable by means of a Setpoint generator 29.
- FIG. 1 shows the following: It may be desirable in the changing bed 19 to build up a compressed air cushion, thereby the weight of the Counteract paper roll (s) 3.1. This is intended to reduce the burden of Paper web at the support points 11 and 12 can be reduced.
- the purpose of the winding bed 19 is down by means of a sealing arrangement 26 sealed. In the example shown, this is part of a Compressed air box 27, which is connected to a compressed air source 28. For Cleaning purposes or to remove reject paper can Sealing arrangement 26, 27 are removed downwards. That in the changing bed 19 resulting compressed air cushion is also not shown Side shields sealed to the outside.
- the Adhesive dispenser 5 activated, for example until time D. Wear this on the paper web 3 on several adhesive traces 6 (see again Fig. 11).
- the entire slitter winder can e.g. shut down become; immediately afterwards (time F) the reel (s) are ejected 3.1, whereby the web is cut along the weakening point 8.
- the creep speed k remains constant from time B onwards, this is done stopping earlier, namely at time E '. This also happens Roll ejection earlier, namely at time F '.
- Another acceleration the entire process can be achieved in that the machine also when ejecting rolls and when inserting new ones Winding sleeves (9, Fig. 5) continues slowly, e.g. at the speed m, which is less than the creep speed k.
- FIGS. 3 to 5 The processes just described are repeated in FIGS. 3 to 5 shown.
- the weakening point 8 has just been created in FIG. 3; the Perforation device 4 is emerging from web 3 again. After that it remains in the rest position (see Figures 4 and 5).
- FIG. 3 shows the state at time C. of Figure 2; i.e. the adhesive dispensers 5 have just started Apply traces of adhesive 6 to the paper web 3.
- Figure 4 shows the State at time D in FIG. 2.
- the weakening point 8 almost arrived at the glue dispenser 5; that's why now Glue application finished.
- the distance from the end of the adhesive traces 6 to the weakening point 8 is therefore very small; it can be almost zero become.
- FIG. 5 shows the state at time E or shortly before this time.
- the traces of adhesive 6 are partially (or entirely) through Support point 11 (contact line between the paper roll 3.1 and the support roller 1) walked through.
- Support point 11 contact line between the paper roll 3.1 and the support roller 1.
- the machine will continue to slow down or at this point stopped; the paper roll (s) 3.1 is / are ejected.
- the through the cutting of the new beginning of the path is created under the Effect of the negative pressure inside the perforated support roller 1 prevails, held onto the roller shell.
- the embodiment according to FIGS. 6-8 is a Carrier roller winding machine with a central carrier roller 1 and with two outer carrier rollers 2.1 and 2.2 arranged on both sides. So two Changing beds are formed, one of which receives at least one paper roll 3.1 and the other at least one paper roll 3.2, each with a winding tube 9.1, 9.2.
- the paper web 3 is shown by - not shown - Slitter divided into a number of partial webs that are on the central one Accelerate roller 1. These are seen in a top view of the machine Partial webs alternately rolled up in the left and right changing beds (similar to Fig. 11).
- Each paper roll 3.1, 3.2 is in a known manner Guide heads, not shown, which are inserted into the sleeves 9.1, 9.2 intervention.
- Each partial web has one or more adhesive dispensers 5 (or 5a, 5b) assigned.
- the perforating device 4 extends over the entire Machine width.
- Each paper roll 3.1, 3.2 is one (only symbolic shown) associated ejector 18. The machine works in essentially like the double carrier roll winding machine according to FIGS. 1-5, but with the following differences:
- the Distance between the weakening points 8 'and 8' ' is chosen so that at the same time the second weakening point 8 ′′ the support point 4.1 of the roll 3.1 almost reached on the central support roller 1 '.
- the machine has stopped (or is running) further reduced speed m), the ejection of the rollers 3.1 and 3.2 with the help of the ejection devices 18 takes place in different ways as follows: On the first outer support roller 2.1, a brake 17 activated so that the role 3.1 when ejecting the stationary Carrier roller 2.1 rolls.
- the second outer support roller 2.2 remains free rotatable so that when the roller 3.2 is ejected, the latter and the roller 2.2 roll on each other like a rotating pair of gears (symbolic represented by arrows 36 and 37).
- Roller ejection in the area of the weakening point 8 '(on the roller 3.2) or 8' ' (on the roller 3.1) generates a high longitudinal tension in the web, so that it is severed properly. That the first weakening point 8 'also in the partial web for role 3.1 is not disturbing.
- FIG. 6 The embodiment shown in Figures 6 to 8 can be like Modify as follows: You can omit the outer support rollers 2.1 and 2.2 (as indicated by dash-dotted lines in FIG. 6). In this case the paper rolls 3.1 and 3.2 alone by means of not shown Guide bearings, which engage in the sleeves 9.1 and 9.2, in their position the support roller 1 'held. Incorporation of the weakening points 8 'and 8' ' and the application of the adhesive 6 'and 6' 'is in principle the same as described above.
- rollers 3.1 and 3.2 are preferably ejected when the Weakening point 8 '' is just before the support point 4.1 (as in Figure 8) and if at the same time the weakening point 8 '(deviating of Figure 8) shortly before the support point 4.3 of the roller 3.2 on the support roller 1 ' located.
- FIG. 9 shows a double carrier roll winding machine in which the Paper web 3 not from below but from above into the winding bed 19 comes in.
- the first support roller 1 may be without perforation, that is as normal non-absorbent roller.
- the condition is shown at time E when the machine is at a standstill.
- the adhesive application 6 and the weakening point 8 are beyond the support point 11 into the Area of the support point 12 arrives, so that now the ejection of the Roll (s) 3.1 takes place on the support roller 2.
- the winding bed 19 a compressed air cushion can be built up.
- the arrangement according to FIG. 9 is Particularly suitable for relatively airtight paper types because of the Compressed air cushion - due to the paper web running from above into the Changing bed 19 - no air can get between the layers of paper.
- Different in Figure 1 Here it is possible that at the gap 11 air from the Compressed air cushion gets between the layers of the paper web. That turns into with airtight paper grades there is a risk that the outer layers on the side run and / or that a bubble is formed in front of the support point 12. At On the other hand, thin, porous types of paper do not have this danger, for air can escape again.
- the weakening device 4 is in all embodiments preferably as a perforating device according to DE-GM 295 08 732.3 educated.
- the essential parts are a shaft with a Perforation comb 4a, which turns the shaft into the web immersed.
- the web is by means of an example.
