Definitions

  • the invention relates to a winding device according to the Preamble of claim 1.
  • EP 0 258 533 A2 shows such a winding device with a backup roller, on the winding rollers during winding lie sideways from above.
  • the winding rolls are held by pedestals on which mandrels on mandrel carriers in relation to the support roller radially, i.e. diagonally upwards, are slidable to one To be able to follow the increase of the winding roll diameter.
  • a sleeve gripper is used to feed new winding tubes provided that associated with a winding block is.
  • the winding tube gripper grasps winding tubes that fed on a feed path above the support roller are and leads them essentially parallel to the scope the back-up roller to a position where it is from the Mandrels can be gripped.
  • the feed path consists of two rails, each of which is attached to a support that adjusted in height independently of the other carrier can be.
  • the individual roll cores of a set are successively shifted into the respective axial position, which is assigned to a winding position. There become by lifting one or the other rail stored laterally and in brackets from which it also when the assigned carrier is raised again can no longer roll out. This makes it possible to separate the roll cores, i.e. on the individual Distribute winding position groups.
  • the bearers then with all the roll cores on it along a given, essentially straight line Trajectory raised so that the individual mandrels in every winding position in the roll cores can be retracted.
  • the feed path is above provided a backup roller assembly.
  • the feed path consists of a tube closed at the bottom that opens can be.
  • There are tentacles below the tube provided that the tips are directed upwards are and protrude through a central plane below the pipe.
  • the individual roll cores are made with the help of Tentacles on one side or the other of the middle plane derived.
  • the tentacles can also go down be folded away.
  • the roll cores then fall on one roof-like distribution device to their winding positions to roll. However, this winding device comes without the bearing pins on the axially displaceable Goats out.
  • the invention is based on the object, the charging a winding device with roll cores at one to design a high degree of automation possibilities that the cutting plan remains flexible and the Construction is simple.
  • This task is the beginning of a winding device mentioned type solved in that the feed path is arranged below the backup roller assembly, the Bearing mandrels arranged next to the backup roller arrangement and the head is a non-linear movement path outside around the backup roller assembly, which by a translatory part and by a Swivel portion is formed, the translational Share is temporally decoupled from the swivel share.
  • the gripper can be put together be moved in the axial direction with a trestle. To this Way you make sure that the gripper is always in is a position in which he has a core role that is in the corresponding winding position with a material web to be wound into a winding roll and placed in the wrapping position can. It is no longer necessary to use all roll cores to move together. Rather, it can be any core role are handled individually, which does not exclude that at the same time several roll cores from the feed path be brought into the winding position. All roll cores can, however, together in the winding device be introduced. Only the order and the axial alignment to the winding positions must be correct.
  • the feed path can be added without the need for additional Movements are kept rigid. She must just support the roll cores from below and one Accessibility from another side, for example from above or from the side or from above and from have the page ready. Then is only for the grippers a movement from the feed path to the mandrels necessary, but they are relatively easy to implement can. Linear movements would be exclusively run on a straight line or a circular line. In order to one not only avoids a collision between the Back-up roller arrangement and the head of the gripper. you is also in the dimensioning of the backup roller assembly free. For example, when the backup roller assembly is formed by a single backup roller can have a relatively large diameter, which improves stiffness.
  • the movement has one linear component, for example by a linear drive, realized like a piston-cylinder arrangement can be, and a swivel component that by pivoting the piston-cylinder arrangement generated by a suitably trained motor can be.
  • the trajectory consists of clearly separated ones Sections that run in succession. Only one drive must be in at a time Be put into operation, which further simplifies the control. Accordingly, the control device can be carried out relatively inexpensively.
  • the gripper is attached to its trestle. This makes it easier the controlled movement of the gripper together with the goat. As soon as the goat is moved, what for example necessary when changing the cutting plan the gripper is also moved. That way poses one makes sure with very simple means that in every Winding position of the gripper is present.
  • Each trestle preferably has a gripper. This further facilitates handling. You make sure that each roll core is gripped at two points can be. These two points are because of the gripper attached to the trestle, adjacent the ends of the roll core. This results in very stable storage. The The roll core cannot tip over during transport. At the same time, the roll core is held where the Bearings should be introduced into it, namely on The End. This means that even with less stable roll cores a very precise assignment between the position of the roll core and the position of the mandrels possible.
  • the two grippers on the sides of the trestles facing one another Pair are arranged. You are now automatically within an axial length that also extends the roll core is located. Further measures to the Then align the gripper axially to the roll core not necessary anymore.
  • the movement path is preferably a translatory one Portion and formed by a swivel portion.
  • the translational part is advantageously by two Sections before and after the swivel portion educated.
  • the head grabs a roll core, will retracted, swiveled and then extended again. This relatively simple movement is enough to get the roll core collision-free outside around the support roller arrangement around carry.
  • the Feed path arranged an adhesive application device, which the individual roll cores depending on the intended winding position group at a predetermined Provides peripheral portion with adhesive.
  • the individual Roll cores in the individual winding position groups relative a different orientation to the backup roller arrangement to have. If the material webs fed, the should be wound up without further handling to be attached to the roll cores, then you have to provide a suitable adhesive surface on the roll cores, which is then simply pressed against the material web must be started to start the winding process. If this adhesive surface when inserting the roll cores generated in the winding device, the further Handling easier.
  • a winding device designated 1 overall in FIG. 1 for a slitter has a backup roller 2 on the opposite side when winding Sides of winding rollers 3, 4 are in contact.
  • the winding rolls are wound on roll cores 5, 6 which for example, as winding sleeves made of cardboard could be.
  • the Roll cores With the help of a pressure roller arrangement 7, 8 pressed against the support roller 2. Otherwise they are Roll cores 5, 6 by only shown schematically Drive arrangement 9, 10 driven centrally.
  • the two winding rolls 3, 4 shown are in two different winding position groups 11, 12 arranged. In each of the winding position groups 11, 12 can several winding rollers 3 or 4 wound simultaneously become. The individual winding rolls 3 and 4 have then a certain axial distance from each other, so that the drive assemblies 9, 10 axially in the roll cores 5, 6 can retract.
  • the winding rolls 3 in the winding position group 11 are to the winding rolls 4 of the Winding position group 12 arranged on gap.
  • the Widths of the gaps correspond to the widths, i.e. the axial lengths of the winding rolls in the other Winding position group.
  • the webs to be wound come from a material web 13, which is guided by a cutting device 14 and there it is divided lengthways to the webs to create.
  • Roll cores 16 While the winding rolls 3, 4 are wound up can be a new set or set of roll cores 16 are introduced in the axial direction one after the other and at once, i.e. With a boost. The individual roll cores are previously on the corresponding axial length has been brought. At the The roll cores 16 can be inserted by means of adhesive application devices 17, 18 at certain peripheral areas be made sticky. Here, each time only one of the two adhesive application devices shown 17, 18 put into operation depending on which winding position group 11, 12 of the individual roll core 16 to be wound later should.
  • the bearing pins 19, 20 are on slides 21, 22 rotatably supported, at least one of the two Carriage 21, 22 a rotary drive 23 for driving the Bearing mandrel 20, which is designed here as a mandrel, having.
  • the slides 21, 22 are on trestles 24, 25 supported and there on the support roller 2 to or from your moving away. This is a movement perpendicular to the Drawing plane of Fig. 4. With this movement one can an increasing roll diameter when winding wear.
  • the blocks 24, 25 are in turn on one Foundation 26 can be moved in the direction of a double arrow 27.
  • One can by relocating, for example a shift or a procedure of the jacks 24, 25 cause changes in the cutting plan parallel to the winding axis, i.e. on the one hand, changing changing roll widths and secondly roles in different positions wrap.
  • a gripper 28, 29 is attached to each bracket 24, 25.
  • the gripper 28, 29 is therefore together with the associated one Bock 24, 25 postponed.
  • Each gripper 28, 29 has a piston-cylinder engine 30, 31, the lower End via a rotary drive 32, 37 with the bracket 24, 25 connected is.
  • a head 33, 34 is arranged with which the gripper 28, 29 grasp and hold the roll core 5 can. The detection can be done, for example, by clamping the roll core 5 take place. But it is also possible that suction means not shown in the head are provided to suck the roll core 5.
  • the grippers 28, 29 it is possible for the respective winding position provided roll core 5 to transport from the feed path 15 to the position where the bearing pins 19, 20, which are also called mandrels can be formed, retract into the roll core 5 can. Since the two grippers 28, 29 on the blocks 24, 25 are arranged, they are automatically in the Area of the axial ends of the roller core 5, so that the roller core 5 is supported there and the bearing pins 19, 20 retracted with high reliability can be.
  • Fig. 2a shows the beginning of the transport.
  • the gripper 28 has taken the roller core 16 with his head 33, the lies on the feed path 15 below the support roller 2.
  • a direct pivoting movement of the gripper 28 would not be possible because the head 33 is then on a trajectory 35 would run on which he collide with the backup roller 2 would.
  • the head 33 with the roller core 16 first drawn in (Fig. 2b), the length of the gripper 28 so diminished. If the gripper 28 then one Performs pivoting movement, then the head 33 has one Movement path 36 past the support roller 2. On this Movement path he gets into that shown in Fig. 2c Position. So that the head 33 with the roller core 16 die Reach the desired position in relation to the bearing pin 19 can, the gripper 28 is extended and thus the roller core 16 raised, which is shown in Fig. 2d is.
  • the movement path of the head 33 is again in Fig. 3 shown schematically. It consists of two translational sections 38 that have a pivoting section 39 are connected.
  • the backup roller 2 is shown in broken lines to show that the roller core 16 can be moved outside the support roller 2 is.
  • the path of movement can be divided into two Realize degrees of freedom, namely by a linear Movement by the piston-cylinder assembly 30, 31 the gripper 28 can be accomplished, and by a pivoting movement caused by the rotary drive 32, 37 can be accomplished. Because the individual movement sections can run in succession, the Control can be kept very simple.
