Definitions

  • the present invention relates to a method of and an apparatus for making rolls of sheet material. More particularly this invention concerns a system for winding continuously delivered sheet material, such as polyethylene film. into large-diameter rolls.
  • a central shaft carries two oppositely directed pairs of outrigger arms between which cores are mounted. Both of these cores are rotated at a speed sufficiently high to wind up the foil or film as it is delivered to them. Film is wound around one of the cores until the outside of the roll approaches the rotation axis for the device. At that moment the entire apparatus is rotated through 180. the film is cut. and wrapping is continued on the new upper core. Meanwhile the completed roll is removed and an empty core substituted in its place.
  • Such an apparatus has a relatively limited capacity in that the maximum diameter of a roll can only be equal to twice the radial distance between the periphery of the central shaft of the device and the axis of the core.
  • a relatively tall piece of equipment must be used. thereby making it impractical to stack two or more winders for simultaneous operation.
  • Another difficulty is that it is necessary to provide heavy lifting equipment in order to remove the rather cumbersome rolls from the high machine.
  • Another object is an improved system for winding a continuously delivered sheet onto cores
  • a further object is to provide a relatively small machine, especially low height, which is capable of producing relatively large-diameter rolls.
  • the cores have axes which lie in a common plane with the rotation axis and at an angle of between 20 and 40. preferably to the vertical.
  • the deflecting elements or idler rollers have axes which are also coplanar with the rotation axis and which lie in a plane perpendicular to the plane of the core axis. Therefore in accordance with the present invention it is possible to unload the filled core at the bottom of the device.
  • the apparatus is dimensioned so that the spacing between the axis ofthe lowermost core and the floor is approximately equal to the spacing between this lower core axis and the outer surface of the upper core so that when the lower core is substantially filled, the roll has an outer surface closely approaching the upper core and very near the floor.
  • the machine operator need merely move one ofthe core holders axially outwardly so as to drop this filled core a short distance on to the floor. whence it can be rolled away.
  • the spacing between the core axis is between one-third and two-thirds. preferably one-half. of the spacing between 5 the axes of the elements.
  • These elements are deflecting rollers of cylindrical shape and serve to flatten the sheet and ensure a proper fold-free winding of this sheet onto the core.
  • Yet another feature of the invention resides in the provision of means for continuously feeding the sheet to the winding location including a feed roller above the mounting assemblies and having an axis parallel to the rotation axis thereof.
  • the rotation axis of this feed roller and the rotation axis of the mounting assemblies 5 define a plane lying between and preferably 5.
  • FIG. 1 is a vertical section through the apparatus according to the present invention.
  • FIGS. 2 and 3 are cross-sections taken along lines lI-II and lines Ill-Ill of FIG. 1 respectively;
  • FIGS. 4 and 5 are side views similar to FIG. I illustrating the machine in two stages of its operation
  • FIG. 6 is a side view illustrating the stacking of two similar machines as shown in FIGS. l-S;
  • FIG. 7 is a view similar to FIGS. 4 and 5 indicating in enlarged scale further details of the apparatus according to the present inventionv 6.
  • the apparatus according to the present invention comprises a housing 2 to which is continuously fed a polyethylene film l.
  • a pair of similar mounting assemblies (stars or spiders) 4 and 5 are rotatable on this housing 2 about a horizontal axis 3.
  • Each of these assemblies 4 and 5 comprises a mounting unit 13 carried on a shaft 27 and each carrying a pair of cone holders 6 which define two axes A parallel to and equispaced from the axis 3 and spaced apart by a distance 15.
  • One of the mounting units 13 is provided with a motor 28 which serves to rotate both of the cones 6 carried on the mounting unit.
  • the shafts 27 are slidable in hollow shafts 9 which carry a pair of arms 12 between whose ends extend parallel rollers 8 which lie on axes A parallel to and equispaced from the axis 3 and spaced apart by a distance 14 equal to twice the distance 15.
  • the shafts 27 are slidable within the shaft 9 so as to allow the assemblies 4 and 5 to be displaced between the solid-line position shown in FIG. 2 and the dot-dash line position. Thus an empty space is left between the mounting assemblies.
  • a motor 29 connected to the shafts 9 and 27 serves to rotate the assemblies 4 and 5 periodically about axis 3 through an are equal to 180.
  • the axes A and 3 define a plane P including axes A and perpendicular to a plane I" which includes axis A and lies at an angle of 30 to the horizontal as is shown in FIG. I when the assemblies 4 and 5 are stopped.
  • the sheet I as shown in FIG. 7 is looped over a compensating roller [8 carried on arm 30 and adapted to swing about a horizontal axis A" so as to compensate for minor variations in rotation speed. Thereafter the sheet 1 passes over a roller 16 and between a pair of rollers 21 and 22 carried as shown in FIG. 7 on a pair of arms 23 pivotal about a horizontal axis 24 and con nected via another arm 25 to a hydraulic cylinder 26 which can pivot these arms 23 between the dot-dash line position shown in FIG. 7 and the solid-line position.
  • the roller 22 has an axis A' which defines with the axis 3 an imaginary plane lying at 45 to the horizontal.
  • the apparatus according to the present invention functions as follows:
  • the sheet is allowed to wind up on this lower core until its outer surface very nearly approaches the upper empty core 7.
  • the distance between the axis A and the lower core 7 and the floor 31 substantially equal to distance 15 so that as the outside of the roll comes close to the core 7, it also approaches the floor 31 as illustrated in FIGS. 4 and S.
  • the cylinder 26 is actuated to draw the arms 23 down.
  • This brings the roll 21 into contact with the upper rotating core 7 and at the same time brings a heated blade 19 carried by these arms 23 into engagement with that section ofthe sheet 1 extending between the roller 21 and the deflecting roller 8.
  • a blast of air is emitted from nozzles 20 carried on the arms 23 so as to blow the cut end of the sheet I around the upper core 7, thereby causing the sheet to wind around this upper core.
  • the roll 11 is then released from between its two holders 6 and rolled away as shown in FIG. 5.
  • a new core 7 is mounted between those lower holders 6 and the motor 29 is again actuated to swing the mounting assemblies 4 and 5 through and start the cycle over again.
  • An apparatus for forming rolls of a continuously supplied sheet comprising:
  • two mounting assemblies jointly rotatable about a rotation axis and carrying two pairs of holders defining a pair of parallel core axes parallel to said rotation axis and diametrically across said rotation axis from each other.
  • one holder of each of said pairs being provided on each of said assemblies;
  • a method of making rolls of sheet material comprising the steps of:
