Definitions
- the proposed invention relates to the technical field of winding a web or the strips resulting therefrom by cutting according to the preamble of the appended claim 1.
- Such devices are known, for example, from US Pat. No. 817,025.
- web-like material is first drawn off a roll in order to be fed to a slitter. In this slitter, the originally full one
- Width of the web on the unwinding roll is cut into individual narrower strips by slitting, ie cutting in the running direction of the web. These strips alternately run to one of two winding stations, each winding station being formed, for example, by two so-called carrier rolls, that is to say rolls on which at least one roll formed by the winding process is supported, for example on account of its own weight can. Since two winding stations, each with two support rollers, are presented here, it is possible to feed one strip of the one winding location with one pair of support rollers and the other, for example, adjacent strips, to the other pair of support rollers of the other winding location.
- 4,374,575 shows such a device in which the originally wide web at least partially wraps around a central drum or roller in such a way that the individual narrow webs obtained from the wide web by slitting len strips can run towards the one side to the group of forming roles.
- Each group of rollers forming or each individual roller is assigned a separate pressure roller, so that at least two parallel rollers
- Pressure rollers are present in the machine. Basically, however, this machine is also nothing more than a machine with essentially one winding point, i.e. the originally wide web runs towards this winding point, is only divided here into narrower strips so that each strip can be individually wound into a roll.
- a mixed form of back-up roll winder and back-up roll winder can be found, for example, in European patent application 0 616965, in which the individual rolls that form strips are supported against a common back-up drum by means of a pair of relatively small back-up rolls.
- this mixed form of back-up roll winder and carrier roll winder also forms only one winding point, because here too the originally wide web is cut into individual strips only at this winding point with the aid of a longitudinal cutting device, so that the strips obtained by the cutting process alternate in the a carrier roller bed or in the other carrier roller bed can be wrapped.
- the individual features of the exemplary embodiment can each be implemented individually or in several arbitrary combinations with the aid of specialist knowledge of further embodiments of the invention.
- the proposed solution is now explained in more detail on the basis of an exemplary embodiment schematically depicted in the attached figure, which explains the inventive concept and does not limit it.
- the exemplary embodiment can also be modified in various ways or supplemented by further exemplary embodiments without leaving the framework defined by the basic idea.
- the figure does not show any essential machine parts that are well known to the person skilled in the art because of a clearer representation. Rather, the figure shows only those parts which are necessary for a more detailed explanation of the proposed solution and its advantages.
- a web 1 made of paper, foil, fabric, metal, plastic or the like runs in the direction of arrow 2 via guide rollers 3, 4, 5 and 6 to a deflection drum 7.
- the deflecting drum 7 is able to cooperate with at least one upper knife 8, so that for example the deflecting drum 7 and the at least one upper knife 8 represent a cutting device which is capable of cutting the up to here in the direction of travel of the web 1, ie in the direction of the arrow 2 to divide the web, which has not been divided in its full or substantially full width, into individual narrower strips at this point.
- several upper knives 8 can be arranged one behind the other.
- both a plurality of support rollers 9 and a plurality of support rollers 10 can be arranged one behind the other in the direction of view of the figure, as is previously known.
- Each roll 12 or the winding shaft or winding tube assigned to it is supported by means of at least one support arm 13 during the winding process rotatably supported.
- Each roller 11 is rotatably supported during de 5 winding operation of at least one support arm 14th
- a plurality of support arms 13 and 14 can be arranged one behind the other in the direction of view of the figure, for example in such a way that two such support arms can support a forming role, the winding shaft assigned to them or the winding tube.
- the support arms 13 and 14 are also provided with devices which allow the respective role being formed against the associated one
- support arms 13 and 14 are pivotally mounted on slides 17 and 18 with the aid of joints 15 and 16.
- Carriages 17 and 18 are supported, for example, on a guide 19, so that the support arms 13 and 14 can be adjusted according to the width of the strips to be wound into the rolls 11 and 12 in the direction of view of the figure and can be fixed at the desired location.
- Positions 6 to 19 in their entirety represent a first winding station.
- the proposed device contains a second winding station, which contains, for example, a support roller 20. Rollers 21 and 22 which are formed can be supported on this support roller during the winding process.
- the roller 22 is rotatably supported and held by means of at least one support lever 23 and the roller 21 by means of at least one support lever 24 during the winding process.
- the forming roll or rolls 22 are pressed with the aid of two Back-up rolls 25 and 26, which are rotatably mounted in a frame 27.
- the frame 27 can be pivoted with the aid of a pivot lever 28 about the pivot point 29 fixed to the frame with the aid of a pressure medium cylinder 30 in the direction of the arrow 31.
- the roller 21 or the rollers 21 are fastened and supported in an analogous manner to the roller 22.
- the web 1 can be fed to the second winding station with the aid of guide rollers 32, 33 and 34.
- a cutting device with an upper knife 35 divide the web 1 into individual narrower strips so that they can be wound up either to the roll 21 or the roll 22.
- the guide roller 34 can simultaneously be the lower knife to the upper knife 35.
- the figure also shows a switch 36 which can be pivoted about the pivot point 38 with the aid of a pressure medium cylinder 37.
- the switch 36 which represents a deflection device for the web 1 can additionally be provided with a knife which is capable of cutting the Pahn 1 in its entirety transversely to its direction of travel if necessary.
- the switch 36 can be pivoted in such a way that the web 1, in its substantially full width, is either a guide channel 39 or else can lead to a guide channel 40.
- the guide channel 39 feeds the web 1 in its full width to the first winding point, while the guide channel 40 feeds the web 1 in its full width to the second winding point.
- the guide channels 39 and 40 can consist, for example, of guide plates or guide rods, care being taken that the web is pushed through or dragged through the respective guide channel until the respective winding point is reached. This can be done, for example, in that air nozzles which are capable of carrying the web are arranged at an angle to the running direction on the inner sides of the respective guide channels in order to supply or drive the web to the respective winding point by air flow.
- first and the second winding point for the web 1 or the strips cut from it are arranged in the running direction of the web 1 indicated by the arrow 2 behind the switch 36 and in addition at least one cutting device consisting of the at least one upper ⁇ knife 8 and the guide drum 7 of the first winding point and the cutting device with the at least an upper knife 35 and the guide roller 34 is assigned to the second winding point, there is the possibility of moving the web in its running direction not only over the guide rollers 3 and 4 in its full width up to the guide roller 5, but also over it depending on the position of the switch 36 to essentially lead to the deflection drum 7 or in the other case to the guide roller 34.
- the one winding point - for example the first one - in such a way that the support arms 13 and 14 are fixed at certain positions along the guide 19 or at all to dispense with a slide guide for the guide 19, so that the Support arms 13 and 14 can maintain immovable positions.
- the support arms 13 and 14 and the support levers 23 and 24 it is possible to set the support arms 13 and 14 and the support levers 23 and 24 such that, for example, the support arms 13 and 14 maintain a different distance or different distances from one another than is the case with the support levers 23 and 24.
- the full one in one, for example in the second, winding station Width of the web 1 can be wound up, whereas the first winding point is set up to wind up certain narrower strips obtained from the web into relatively narrow rolls 11 and 12.
- the guide channel 39 contains, for example, the guide plate 41, the guide channel 40, for example, the guide plates 42 and 43. So that the support levers 23 and 24 can be appropriately guided during the winding process, they are provided with joints 44 and 45, about which they can be pivoted.
- the second winding point In the running direction of the web 1 indicated by the arrow 2, the second winding point, seen in the running direction, lies purely externally behind the first winding point, although both winding points can be operated alternately with the help of the web deflection device implemented by the switch 36.
- a carrier roller winder which contains at least one, but usually two carrier rollers, which take up the weight of at least one roller formed by the winding process and which supports at least one roller, so to speak, from below, it has backup rollers ⁇ winder as another type of winding device in the sense of the present invention, at least one roller or the like, to which the at least one roll forming during the winding process can lean, ie can be essentially supported.
- such a backup roller winder forms a winding point which, in turn, can comprise a plurality of groups of rolls forming. At least two such winding stations should be arranged one behind the other essentially in the running direction of the web 1.
- the web 1 can, for example, be cut straight at its edges, ie trimmed, before it passes the deflection device, but this does not essentially affect its width.
- a support roller roller represents a specific type of winding machine and a support roller roller, for example, another type.
