Definitions

  • the invention relates to a winding device for winding a roll of material, especially in a slitter, with means for rotating the roller about an axis of rotation.
  • the invention is based on a paper web described as an example of the material web. she is but also applicable to other material webs.
  • the invention is primarily on winding one Material web directed. The explanation is therefore made based on this approach. But it is just as good can be used when unwinding a material web from a roll.
  • the means of rotating the reel can vary limit to a simple roll storage. When winding up however, is often a drive for the role be provided, the means can be a when unwinding Include brake.
  • Paper webs that, after production, ultimately lead to Delivered, are often on winding cores wound, which are formed by cardboard tubes. At the The rolls are therefore wound by support rollers or Support rollers supported because the cardboard tubes in particular no longer the necessary stiffness for wider rolls and have load capacity to deflect the Prevent roll with increasing roll weight.
  • US B 396 551 A shows an automatic tape winding machine for tapes with a length of about 100 m to be wound on a winding roll. in this connection becomes a material web with a highly sensitive surface in a series of parallel ones Cut ribbons.
  • the tapes are made from a horizontal Feed position deflected into a vertical winding position and then wound up. For winding up one Sleeve on a sleeve guide and one-sided held. The exchange of the fully wound sleeve for a new sleeve is made in that the winding axis around Is pivoted down 180 °.
  • DE 1 951 820 A shows a device for feeding a sheet material to a machine for printing of business forms or otherwise Processing the material web.
  • the device comprises a table on which the paper web roll to be unwound with a vertically aligned axis. Can between the end of the roll and the table a compressed air cushion are formed and has this the table has a series of air vents, which are closed by valves. The valves are opened by the paper roll on top.
  • FR 1 521 131 A shows a guide for a role a rubberized tape from a dispenser into a processing machine.
  • the winding roll with the rubberized The tape stands vertically on a turntable.
  • the Belt is then over two vertical pulleys and then passed over an inclined pulley, to move from the vertical plane to a horizontal plane to get. Because of the redirection options, it plays no matter whether the tape with the rubberized side after has been wound outside or inside.
  • the invention is based, one for to create large rolls of usable winder.
  • This task is the beginning of a winding device mentioned type solved in that the axis of rotation stands vertically and a winding rod is provided is that a winding tube of the roll axially completely protrudes, with the winding rod on both sides the roll is held and variable in length is or a height-adjustable counter bearing on the Wrapping rod attacks in the area of the upper end of the roll.
  • the role now wrapped in an upright position i.e. the role is now directed vertically.
  • Your axis of rotation runs in the direction of gravity.
  • the weight forces of the Roll no longer act in the radial direction and accordingly, the weight forces can not Influence more on the winding hardness of the roll.
  • the Rather, the winding hardness of the roll can be within certain limits freely determined and thus also the winding hardness course.
  • the roller is mainly supported over the roll core.
  • the material web must anyway with a certain tension around the core respectively are laid around the lower material web layers, because you have to telescope when handling it later want to avoid. Accordingly, the causes Tension a friction between the individual layers of the Roll that can absorb the weight.
  • the winding rod facilitates the leadership of the role in winding.
  • the winding rod then supports the winding tube over its entire length, so that to the inherent rigidity the winding tube, which is often only designed as a cardboard roll is added to the rigidity of the winding rod. If the winding bar on both sides of the Roll is held, you can tilt the roll when Avoid wrapping. This in turn makes feeding easier the material web in the desired tangential direction. If the winding rod is variable in length you can use them in different roll widths to adjust. This is particularly advantageous if used the winder in a slitter that can produce changing roll widths got to. With a variable length winding rod protrudes the winding rod through the roll.
  • the winding device preferably has a deflection device on which is essentially the web of material horizontal infeed level in an redirects the substantially vertically oriented winding plane, which are aligned tangentially to the circumference of the roll is. So that the material web is wound smoothly on the roll it is recommended that the Material web fed tangentially to the roll or at Unwinding is carried away. At least immediately before The material web strikes the roll therefore in the winding level. This expression is used in following also retained for unwinding. Since the Material web usually from relatively large mother or Jumbo rolls is unwound, it is advantageous if you have these jumbo rolls with a horizontal winding axis can store. The jumbo rolls can be in easier to transport and handle in this location. Around the advantages of horizontal processing with a to be able to connect vertical winding one the deflection device.
  • the deflection device has first guide means that the material web divert into an intermediate level, and second guide means, which the material web from the intermediate level in redirect the winding plane. With such a double One is redirected when guiding the material web free.
  • first guide means in essentially transverse and the second guide means at an angle 45 ° to the running direction of the material web are. You then come with a single redirection in which the guide means are not transverse to the direction of travel the material web, but arranged at an angle are. This facilitates the control of the web run. In particular, you get practically no difference speeds based problems.
  • the intermediate level includes a particularly advantageous one An angle of approximately 90 ° with the feed plane. It has turned out to be from such an intermediate level most easily reached the winding plane.
  • At least one of the guide means is preferably as Guide roller trained. Guide rollers per se are known. They can therefore be used without major reworking.
  • the guide roller is preferably in the form of a bending adjustment roller educated. This can then be used for a wrinkle-free deflection worry and possibly also a certain Fulfill spreading function.
  • At least one of the guide means is designed as an air deflector his.
  • the material web is then with the help an air cushion or with the help of air steel, that they are supported on the redirection can.
  • the width of the web can then be changed set different differential speeds locally.
  • the drive is preferably designed as a center drive. It therefore acts on the winding core or the winding sleeve. Apart from the tensile forces of the incoming The attacking forces act essentially on the material web symmetrical on the roll.
  • the winding rod advantageously has a tensioning device with which it can be fixed to the winding tube is.
  • the winding tube then has a defined position Winding rod. You can use the winding bar at the same time use to drive the roller. Since it is on the winding tube can be determined, it can transmit a torque.
  • Clamping devices are known per se. You can operated pneumatically or mechanically, for example be, the diameter of the winding rod so is increased that the circumference of the winding rod at least in some areas on the inside of the roll core or the winding tube.
  • the tensioning device In both cases it is enough off when segments are in contact with the winding core.
  • the winding rod is preferably telescopic with several mutually displaceable rod sections formed, and the clamping device has several Holding sections, the distances between them during the process change the bar sections.
  • the length of the winding bar can be changed.
  • the bar sections With a short winding tube, i.e. a small one Roll width, the bar sections are moved into each other. With a large roll width, the Rod sections, however, extended. You can now several or even all sections of the winding bar Attach holding sections. If the rod sections are retracted, then they have a low one Distance from each other. When the winding bar is extended then the holding sections have one accordingly greater distance from each other. All roles will held with the same number of sections regardless of their axial length.
  • the holding sections are advantageously in the collapsed state Condition of the winding rod, possibly with Exception of holding sections at the end of the winding bar, to each other.
  • the holding sections then form simultaneously a limitation of the entry movement, so that one can avoid complicated control.
  • a support roller is advantageously parallel to the axis of rotation with its axis arranged in one area which varies from the incoming material web up to one parallel to it and through the axis of rotation Level extends.
  • the support or idler roller could be used to compensate the web tension or to counteract it is with one Roll with vertical axis of rotation is not more easily possible.
  • the backup roller is provided. The back-up roller can withstand such deflection counteract.
  • a stripper roller is advantageous in the area of impact the web of material arranged on the roll.
  • This stripping roller serves to trap air prevent, i.e. squeeze the air out at the point where the ascending web on the reel respectively the role hits. You can use this stripping roller, if necessary together with the backup roller, also use to control the winding hardness and / or the roll to drive the scope.
  • the back-up roller and the stripping roller are advantageous movable towards each other. Then they form a holding device for the material web. This makes it easier the role change, i.e. the conviction of the Material web from a completely wound roll onto the The core of a new role. As long as one with horizontal Axis of rotation is the problem of Keeping the material web of minor importance. The main problem here is how to "re-thread" the web. At a vertical roll, however, must always be taken care of be that the end of the web of material is held is, either by the holding device or by gluing the end to the roll. If letting go of the end, falling would End to a drastic deterioration in quality finished role.
  • Cutting and gluing device arranged. With help this cutting and gluing device can be the end the material web of the finished roll and the beginning of the Material web of the reel to be rewound with one Apply adhesive and then cut through the material web. One end is then on the finished roll glued and the other end to the core of the new one Role.
  • the roller is preferably on a support plate.
  • the Backing plate then absorbs the weight, so that the frictional connection between the winding rod and the winding sleeve essentially loaded only in the circumferential direction becomes.
  • the diameter of the support plate limited to the diameter of the winding tube is.
  • the bottom end of the roll will not used to support the roller. The front will spared with it. The risk of damage is lower.
  • the role is held together by the web tension, i.e. the web tension is designed so that the individual Lay the layers against each other with the necessary friction.
  • the support plate can also be set to the maximum Diameter of the roll can be designed so the individual layers of the material web are supported on it can. This leads to a particularly straight one Face.
  • a pivot drive for pivoting is advantageous the roll from the vertical winding position provided in a horizontal transport position.
  • the finished wound roll can then be removed from its upright position Position are stored, for example on a Transport cart or a conveyor belt. You can also toast and then to another extent Roll position. With a horizontal winding bar it is also easier to find a new role core postpone.
  • winding stations are included arranged vertically parallel to each other Rotation axes provided.
  • Such training is especially intended for a slitter rewinder which divides a material web into several partial webs, which then have to be wound up into partial web rolls.
  • the partial web roles i.e. the roles in the individual Changing stations tend to go up, but where in there is usually enough space.
  • the management of the material web to the individual winding stations becomes easier once the material web is in the required has been brought upright.
  • One is therefore with the arrangement of the winding stations more freely than with conventional winders with horizontal axes of rotation.
  • the lower ends of the rolls in all winding stations essentially in are arranged at the same height. Then at most they occur Differences at the top of the reels. The roles can all be done in the same way be handled.
  • the deflection devices are advantageous for the individual Winding stations in the feed level in two directions offset against each other. So you are one in the running direction and on the other hand transverse to the running direction the material web offset.
  • the winding stations are particularly advantageous on one arranged common carrier which is movable. So you can, for example, the individual winding positions move to positions where they are more easily accessible are, for example, with a new one To provide the roll core and prepare it. To the The winding position can be rolled up or further wound then be moved together with the carrier, which makes handling easier. In particular, results then automatically when moving a winding position moving the other winding positions so that one can achieve multiple effects in one operation.
  • the carrier is preferably about a vertical axis rotatable, around which the winding positions are arranged are.

  • the carrier has a common drive drum for several winding positions to which the rolls of the winding positions can be pressed are. With the drive drum everyone gets to it pressed winding rolls the same peripheral speed taught. This is especially important if all rolls with partial webs from the same material web be supplied. In addition, the Train tension can be influenced.
  • the winding positions are preferably in at least divided two winding position groups and only the winding positions a winding position group are simultaneous active. This has the advantage of having the roles can wrap in the active winding position group while one at the same time the winding positions of the others Can prepare or prepare the winding position group especially remove the finished rolls and one can insert new roll core.
  • the winding positions of both winding position groups alternately on the Carriers are arranged. It is then enough, the carrier a division, i.e. the distance between two winding position groups, to move (or the web of material accordingly to redirect this distance) if one from a finished roll to a new roll core wants to transfer. This also saves Space. You don't have to go that far anymore spaced apart that two full rolls of space to have. It is enough if a full role and one Roll core have room if you still have a certain one Leaves room for maneuver.
  • the invention is based on a slitter described for paper webs. but she is also suitable for other purposes, such as rewinders and bad roll cutters or when opening or closing Unwinding of other material webs.
