Definitions

  • the present invention relates to guiding rollers for calendeis, especially glazing calenders, with a tubular mantle rotatable by bearing means about a stationary axle, said mantle being divided along at least one plane perpendicular to its longitudinal axis.
  • customarily guiding rollers are employed which are intended to so influence the path of the goods or web of goods from one calender gap or bite to the other that no air or steam bubbles and folds of the goods move into the bite of the rollers.
  • the heretofore customary guiding rollers with undivided tubular roller mantle do not afford any possibility of compensating for a bend. Therefore, the diameter of such guiding rollers should be so selected that the bend of the guiding roller remains within small limits.
  • continuously increasing guiding roller diameters become necessary. As a result thereof, the distance between the guiding roller and thus also between the servicing platform and the roller gap or bite increases automatically whereby the manual introduction of the web of goods into the bite is made considerably more difficult.
  • the large fly wheel or gyrating mass of such guiding rollers impedes the starting of such guiding rollers and their movement by the frictional forces of the web of goods as well as the stopping of such guiding rollers when a tear occurs in the web of goods.
  • guiding rollers In order to compensate for the bend of guiding rollers having a great length, guiding rollers have been suggested which are provided with a mantle of two tubular sections which are rotatable one behind the other through the intervention of two self-aligning bearings and are joumalled on a stationary shaft. While the bearing means arranged toward the center of the roller are always concentrically supported by the axle, the two bearings at the ends of the guiding roller are adapted through the intervention of two eccentric bushings arranged one within the other to be adjusted eccentrically in conformity with the bend of the axle. This compensation of the bend by means of eccentric bushings is, however, not possible during the movement of the goods.
  • FIG. 1 shows the arrangement of a guiding roller with regard to the pertaining calender rollers.
  • FIG. 2 illustrates a heretofore known guiding roller with a twosectional roller mantle and with the stress analysis pertaining thereto.
  • FIG. 3 represents a guiding roller according to the invention with a three-sectional roller mantle and the stress analysis pertaining thereto.
  • FIG. 4 represents a longitudinal section through a guiding roller according to the invention.
  • FIG. 5 illustrates on a larger scale than that of FIG. 4 an adjusting device according to the invention for compensating for a bend of the guiding roller.
  • FIG. 6 is a cross-section taken along the line Vl-Vl of FIG. 5.
  • the guiding roller according to the present invention is characterized primarily in that a bushing is placed over the axle end pivot while the cylindrical surface section of the bushing has by means of a self-aligning bearing rotatably journalled thereon the outer end of each roller mantle section, said bushing being displaceable relative to the axle end pivots by hydraulic, pneumatic or mechanical adjusting means through the intervention of the flat guiding surfaces of the bushing and a section of the axle end pivots which have parallel plane surfaces.
  • the said adjusting means engage bolts rigidly connected to said pivots and extending perpendicularly thereto or therethrough.
  • the present invention thus consists in a novel eccentric adjusting device to compensate for the axial bend of the guiding roller, said adjusting device being operable during the movement of the goods and during the rotation of the mantle of the guiding roller.
  • roller mantle may consist of three tubular sections which in the longitudinal direction of the roller are arranged one behind the other and which are independently of each other rotatable on the roller shafi.
  • a further reduction in the diameter of the guiding roller can be realized over a heretofore known guiding roller with a two-sectional mantle.
  • the means for compensating for the axial bend may consist of a screw engaging a threaded bore in the bolt and being rotatably but longitudinally non-displaceably radially inserted into the bushing.
  • hydraulically or pneumatically actuated means may be provided for compensating the bend of the guiding roller.
  • FIG. 1 illustrates the arrangement of a guiding roller 1 relative to the calender rollers 2 which latter with each other form the roller gap or bite 3.
  • the web of goods 4 hits the guiding roller 1 at the incoming angle 5 and leaves the guiding roller 1 after forming a looping angle 6 at the outgoing angle 7.
  • the pulling force 8 exerted by the web of goods at the incoming side, the pulling force 9 of the goods on the outgoing side, and the vertical force of gravity 10 of the guiding roller 1 together produce the resulting force 11 on which the bend of the guiding roller depends. It will be obvious that changes in the angles 5, 6 and 7 as they occur frequently when the diameter of the calender rollers 2 is changed, will influence or affect the size and angular position of the bend of the guiding roller 1.
  • the adjusting device according to the invention for compensating for an axial bend will now be described in connection with FIGS. 4-6.
  • the three tubular sections 14, I6 and 14a are in axial arrangement one behind the other by means of self-aligning bearings 15 rotatably joumalled on the stationary guiding roller shaft 12.
  • the guiding roller shaft 12 is by means of its pivots 12a supported in customary manner in bearings 13 which are mounted on supports 17 on the bearing housing of the calender rollers or the connecting surfaces of the calender stands.
  • the outer bearings of the tubular sections 14, 14a do not directly rest on the shaft 12 but rest on a cylindrical surface section of a bushing 18 which surrounds the pivots 12a.
  • a flat guiding surface 20a through which extend the shaft pivots 12a.
  • the pivots 12a are within the region of the flat surface means 20a of bushing 18 provided with parallel plane surfaces 20 which are located opposite to adjacent plane surfaces 18a of the bushing 18.
  • Bushing 18 is displaceably guided with its surface means 18a by said plane surfaces 20.
  • the spacing between the oppositely located plane surfaces of the pivot 12a therefore corresponds to the width of the flat guiding surface means 180 the height of which is greater than the diameter of the pivot section which passes through the flat guiding surface means 18a.
  • a bolt 21 passes through each pivot 12a and is rigidly connected thereto by means of a transverse bolt 22.
  • a bolt could be welded to or screwed into the pivot 12a in a direction perpendicular to the longitudinal axis of pivot 12a.
  • Means referred to in detail further below are provided for displacing the bushing 18 and the ends of the tubular sections 14, 14a of the roller mantle which sections are joumalled on the bushing 18. These means engage the pivots 12a of the guiding roller shaft 12 eccentrically with regard to the pivots 12a through the intervention of the respective bolt 21 and through the flat guiding surface means 18a in bushing 18. In this way, when the guiding roller shaft is bent, an alignment of the tubular sections of the roller mantle can be realized.
  • the novel and advantageous feature of the present invention is seen in the possibility of effecting the adjustment during the operation, i.e. during the rotation of the guiding roller, so that a straightening of the roller mantle can be obtained when an axial bend occurs.
  • a screw 19 is radially rotatably inserted into the bushing 18 but is longitudinally non-displaceable.
  • Screw 19 has its threaded section 19a in threaded engagement with an axial threaded bore 21a of bolts 21.
  • its threaded section 19a will more or less enter the threaded bore 21a of bolt 21 whereby the bushing 18 and consequently also the roller mantle sections 14, 14a rotatably joumalled thereon are displaced relative to the pivot 12a.
  • a clamping connection 23 (FIG. 4) may be provided.
  • the guiding roller shaft 12 can be arrested after a rotation in any desired position.
  • surface 18a and bushing 18 rotate so that a bend of the guiding roller shaft 12 in any angular position can be compensated for by the above mentioned adjusting means according to the invention.
  • a guiding roller structure which includes: a shaft having a pivot at each end, a plurality of substantially axially aligned tubular mantle sections surrounding said shaft and being rotatably supported thereby, said tubular sections extending over the major portions of the length of said shaft and their outer surface forming the guidin surface of said guiding roller structure, each of said pivots 0 said shaft adjacent the outer ends of the end mantle sections having two substantially plane and parallel guiding surfaces located opposite each other, bushing means respectively arranged around said pivots, each of said bushing means having its inside provided with two substantially parallel sides longer than that diameter of the pertaining pivot which is located in that plane of symmetry of the pertaining pivot which is parallel to said parallel guiding surfaces thereof so as to permit a relative displacement of said bushing means with respect to the pertaining pivot, two selfaligning antifriction bearing means respectively interposed between said bushing means and the adjacent end portion of the respective adjacent tubular section for rotatably supporting the latter, and actuating means respectively associated with said bushing means and operable
  • a guiding roller structure according to claim 1 in which said shaft is surrounded by three substantially axially aligned tubular mantle sections, separate bearing means being provided for rotatably supporting said mantle sections independently of each other.
  • each of said actuating means respectively associated with said bushing means includes: bolt means extending through and connected to the pertaining pivot and having one end provided with a threaded hole, and a threaded pin axially non-displaceably connected to the pertaining bushing means and threadedly and adjustably engaging the threaded hole in said bolt means.
