Abstract
In winding machines, known roll systems are used that contain a number of freely rotatable roll segments (3), which are situated next to one another face to face and mounted in a manner that enables them to move perpendicular to their rotation axis (4). According to the invention, the roll segments (3) are mounted so that only one respective face is mounted on a bearing journal (5), which is fastened in an interspaced manner to a bearing plate (6) that can move perpendicular to the rotation axis (4). An annular slot (15) is fashioned in at least one inner side of each bearing plate (6), and the end of a roll segment (3) can rotate without touching inside this annular slot.
Description
- The invention relates to a roll system, especially a contact roll system, for a winding machine having a multiplicity of roll segments which are journaled adjacent one another end face to end face for free rotation and are movable perpendicularly to their rotation axis and to a winding machine for winding up a traveling web of material, especially a paper web or a web of plastic foil or film, which contains the roll system as a contact roll system.
- In winding machines for the winding up of continuous traveling webs of material, especially paper webs or webs of plastic foil or film, contact rolls are used in a known manner as pressing rolls or squeezing rolls, especially in the case of high winding speeds, to prevent the incorporation of air into the wound roll as much as possible. When the winding machine is used for winding up a web of material which has been subdivided by longitudinal cuts into a plurality of wound rolls which are to have cores or sleeves on which the rolls are wound and which are contiguous or flush with one another, the contact roll for each wound roll must be individually movable to compensate for unavoidable diameter differences in the wound rolls. The axial length of a contact roll must thus be equal to or greater than the width of the wound roll against which it presses.
- DE 198 05 412-A1 and DE 198 48 532-A1 describe an advantageous roll system of the type which has been described in which each roll segment is held in a frame which is mounted so as to be movable perpendicularly to the rotation axis. Each frame of a roll segment contains two bearing plates which extend laterally and parallel to the end faces of a roll segment whereby the neighboring bearing plates of two roll segments are arranged one over the other perpendicular to the movement direction. The bearing plates have deep annular grooves in which end faces of the roll segments can rotate in a contactless manner. This arrangement enables each roll segment to be pressed individually against a wound roll and at the same time permits the gap between two neighboring roll segments to be held very small and thereby avoids markings on the wound rolls.
- The invention has as its object to simplify structurally a roll system of the type described.
- This object is attained in that the roll segments are each journaled only at one end face on a bearing pin which is mounted to project perpendicularly from a bearing plate which is movable perpendicularly to the rotation axis.
- By the advantageous embodiment according to
patent claim 2, each two roll segments are held by a common bearing plate from which the bearing pins project to opposite sides. - In order to hold the spacing between two roll segments as small as possible, in an especially advantageous embodiment according to
patent claim 3, in at least in an inner side of each bearing plate, an annular groove is machined in which an end of a roll segment can rotate contactlessly. - The further dependent claims contain preferred and especially advantageous refinements of the invention.
- The drawing serves for clarification of the invention based upon a simplified illustrated embodiment. The drawings thus show in
-
FIG. 1 the side view of a contact roll system according to the invention, -
FIG. 2 a cross section broken away through a first embodiment in which the two roll segments are held by a common plate, -
FIG. 3 a plan view of the contact roll system according toFIG. 2 and -
FIG. 4 a cross section through a second embodiment in which each bearing plate carries only one roll segment. - The contact roll system illustrated in the Figures is a component of a winding machine for winding up a continuous traveling
material web 1, especially a paper web or a web of a plastic film or foil. Thematerial web 1 subdivided by longitudinal cuts, is wound up on sleeves towound rolls 2. Thewound rolls 2 are mounted for the winding upon a common winding shaft or are each held by two clamping heads insertable into the sleeve. In order to prevent the penetration of air into thewound rolls 2, especially at high winding speeds, the winding machine has a contact roll system which is described in greater detail subsequently. - The contact roll system comprises a row of
roll segments 3 arranged adjacent one another, end face to end face, and whose axial lengths are smaller than the minimum width of awound roll 2. In the embodiment described, the length of aroll segment 3 is 50 mm to 150 mm. Each roll segment is either individually or as part of a pair together with a second roll segment, mounted so as to be movable perpendicular to itsrotation axis 4. Anindividual roll segment 3 or a pair of two roll segments 3.1, 3.2 can thus press independently from the other roll segments against arespective wound roll 2 to permit diameter differences in thewound rolls 2 to be compensated. - Each
roll segment 3 is journaled at one end face on abearing pin 5 in a cantilevered manner, the bearingpin 5 projecting from abearing plate 6 upon which it is fixed. Thebearing plates 6 are movable perpendicularly to therotation axes 4 of theroll segments 3, preferably by means of respective drives which are individual to the bearing plates. In the embodiment illustrated, thebearing plates 6 are shiftably mounted for movement back and forth with respect to thewound roll 2. For this purpose they have on their backsides turned away from thewound roll 2, arespective shank 7 with which they are slidably mounted in alinear guide 8, preferably a ball guide. Thelinear guides 8 are affixed to atraverse 9 which extends transversely over the working width of the wound machine. Thus ends of thebearing plates 6 with theroll segments 3 are mounted thereon are in turn mounted on the common transversely extendingtraverse 9. A pneumatic piston and cylinder unit can serve as the drive for the shifting movement, and is on the one hand is affixed to asupport plate 11 fastened to thetraverse 9 and on the other hand is fixed to the back side of thebearing plate 6. - As an alternative to the linear mobility illustrated in the Figures, the
bearing plates 6 can also be movably mounted on an arcuate track perpendicular to therotation axis 4. The bearing plates can be mounted so as to be limitedly swingable, for example respectively, on rockers each assigned to one of thebearing plates 6. - As can be seen from the side view of
FIG. 1 , each bearingplate 6 ends at its side opposite the fastening end at a slight distance behind thebearing pin 5 secured thereto. This means that aroll segment 3 extends peripherally beyond the extent of thebearing plate 6. The region of contact with thewound roll 2 is thus maintained free from obstruction. Amaterial web 1 running to awinding roll 2 can thus be so guided that it initially contacts aroll segment 3 and then thewinding roll 2. This has advantages from a technological viewpoint with respect to the winding operation. Because of the bevels at the end of thebearing plate 6 turned toward thewinding roll 2, the looping angle of theweb 1 around theroll segment 3 can be adjusted independently of the winding direction and symmetrically for both possible winding directions. The looping angle of theweb 1 on aroll segment 3 amounts to 5° to 30°, preferably between 8° and 20°, for the best ability to wind the web while avoiding the entrainment of air into the roll by adhesion to theweb 1. - Each
roll segment 3 is comprised of anannular roll jacket 13 of metal upon which an outer runninglayer 14 of rubber is applied. At least at an inner side of eachbearing plate 6, anannular groove 15 is machined concentric to thebearing pin 5. The curvature and outer dimensions of theannular groove 15 is so selected that the corresponding end of aroll segment 3 can project into it and can rotate in a contactless manner within theannular groove 15. Thewall 16 remaining as the base of thegroove 15 is made to be extremely thin since it defines the minimum distance between two neighboringroll segments 3. Preferably the thickness of thewall 16 amounts to 1 mm or less. The assembly has an axial free space between the end faces of theroll segments 3 and thewall 16 of about 0.2 mm to 2 mm and preferably about 0.3 mm. In spite of the minimum thickness of thewall 16, the requisite strength for supporting aroll segment 3 is provided since each bearingplate 6 is so shaped that the bending line must also run through thicker regions outside thegroove 15. Theannular groove 15 enables the requisite gap between two neighboring roll segments to be held very small. To avoid marking ofsensitive webs 1, the gap should amount to less than 5 mm and preferably the gap is between 0.8 mm and 5 mm. - In the embodiment of
FIGS. 2 and 3 , two roll segments 3.1 and 3.2 are shown to be respectively journaled on both sides of acommon bearing plate 6. For that purpose each bearingplate 6 has on each side a respective projecting bearing pin 5.1, 5.2 with a roller bearing 12 upon which a rolled segment 3.1, 3.2 is journaled so as to be freely rotatable. Thebearing plates 6 have on both sides respectively an annular groove 15.1, 15.2 in each of which one roll segment 3.1, 3.2 supported by thebearing plate 6 is rotatable. - In
FIG. 4 an embodiment of the invention has been illustrated in which each bearing plate has only one projecting bearingpin 5 on whichroll segment 3 is journaled. Thebearing pins 5 each have a respective flange with which they can be secured by screws to thebearing plate 6. With this embodiment, thebearing plate 6 has only on one inner side anannular groove 15 while the backside is planar and has a surface perpendicular to the axis ofrotation 4. Thebearing pin 5 and theannular grooves 15 are each located on the same side of therespective bearing plates 6 so that the free ends of the roll segments terminate at a slight distance from the rear wall of the neighboring bearing plate. In this embodiment as well, the thickness of thewall 16 at the base of thegroove 15 defines the minimum distance of tworoll segments 3 from one another. Since thebearing plate 6 has anannular groove 15 only at one side, it is simpler to fabricate. - In an embodiment which has not been illustrated, as in the embodiment of
FIG. 2 , each two roll segments 3.1, 3.2 are journaled on both sides of acommon bearing plate 6. The bearingplate 6 is configured as has been illustrated for the embodiment ofFIG. 4 , with only oneannular groove 15 on one side. On the back wall, without a groove, the second bearing pin 5.2 is affixed which carries the second roll segment 3.2. This embodiment has the advantage of the embodiment ofFIG. 12 , namely, that only onebearing plate 6 is provided for each two roll segments 3.1, 3.2. In addition, it utilizes abearing plate 6 of the type shown inFIG. 4 which is simpler to fabricate since it has anannular groove 15 on only one side. - According to a preferred embodiment, two neighboring
bearing plates 6 and thus roll segments held thereby can be mechanically so coupled together that the rotation axes 4 of theroll segments 3 exactly align. Theroll segments 3 which are coupled together thus form a rigid combined pressing roll which can press with a common pressure against a windingroll 2. The contact lines of all rollsegments 3 which are coupled with one another form an exact straight line or flush relationship. A coupling of twoadjoining roll segments 3 has been found to be advantageous when, because of large thickness tolerances in the web, wound rolls 2 can develop excessively great differences in diameter at different zones. It is then undesirable that eachroll segment 3 or each pair of roll segments 3.1, 3.2 match the actual diameter in their respective pressing zones. Acoupling 2 neighboringroll segments 3 is also advantageous whenroll segment 3 with excessive axial length projects beyond wound roll and thus concentrates its pressing force only at the part of its length which is in contact. - As coupling elements, preferably switchable keys or locks 17 are used as has been shown diagrammatically in
FIG. 1 and which may be movable parallel to therotation axis 4 on theshank 7 of abearing plate 6. Thelock 17 can be actuated, for example magnetically or by a pneumatic cylinder to engage with its end in a corresponding opening of the shank of the neighboringbearing plate 6.
