Definitions

  • ABSTRACT In a roller driving system for feeding sheet materials comprising a plurality of roller pair units in series, the sheet material being passed from roller pair unit to roller pair unit by being nipped between the two rollers of a roller pair unit which are rotating in opposite directions with reference to each other, at least one roller of a roller pair being driven by driving means, the improvement wherein the number of the driving means on one side of at least a portion of the roller system is substantially the same as the number of driving means on the other side of the roller system, such that across any two alternate roller pair units the nipping pressure applied to the sheet material in a direction perpendicular to and across the direction of sheet material flow is substantially equal.
  • This invention relates to a driving system for one or more pairs of rollers for feeding sheet materials, more particularly to an improved driving arrangement for one or more pair of rollers in a sheet material feeding system in which sheet materials as well as web materials (hereinafter all such materials are called sheet mate rial in this specification) are fed for processing.
  • the pressure of nipping is higher at the stationarilyfixed end of the shafts than at the driven end of the shafts, which is believed to be due to the fact that the pressure of nipping at the driven side of the rollers is lowered due to a repelling effect set up between the driving means, e.g., meshing gears.
  • Another object of the present invention is to provide a driving system for sheet material roller feeding sys tems in which fluid application onto the sheet material can be performed uniformly from end to end of the sheet material.
  • roller driving means are balanced across a pair of rollers, or adjacent pairs of rollers, so as to equalize the applied pressure in a direction along the long axis of the rollers over a pair of rollers or over adjacent pairs of rollers.
  • FIG. 1 is a front view showing a pair of rollers nipping a sheet material.
  • FIG. 2 is a graphical representation showing the distribution of the nipping pressure between a pair of rollers and the lateral position of the rollers.
  • FIG. 3 is a plan view showing a pair of rollers with a driving system in accordance with the present invention illustrated together with complementary graphs showing the lateral distribution of the nipping pressure along the rollers.
  • FIG. 4 is a left side view of one embodiment of the invention.
  • FIG. 5 is a plan view of the embodiment of FIG. 4.
  • FIG. 6 is a right side view of the embodiment of FIG. 6.
  • FIG. 7 is a front view showing a further embodiment of the present invention.
  • FIG. I a pair of gears la and lb are fixed to an end of shafts 2a and 2b protruding from rollers 3a and 3b.
  • a sheet material 4 is shown nipped therebetween.
  • the other end of shafts 2a and 2b of the rollers are supported in stationary supporting means (not shown) such as bearings or holes provided in an end plate.
  • the pressure of nipping exerted by the rollers on sheet material 4 has been proven to be as shown in the graph FIG. 2, wherein the pressure (p) of nipping increases from the driven end of the rollers to the nondriven end of the rollers.
  • the roller pair 3a and 3b is arranged so that the total nipping pressure is equal from end to end, as shown in FIG. 3, by changing the driven side of the roller in the roller pair.
  • the sum of the nipping pressure (p) at any one position along the nipping surface of the roller pair is substantially equal to the sum of the nipping pressure exerted at other positions along the nipping surface.
  • the total nipping pressure exerted on any one position of the sheet material is made substantially equal to that exerted on any other positions by making the number of driving gears on one side of the roller pair equal to the number of driving gears on the other side of the roller pair.
  • the end of the shaft of the roller is further provided with a worm wheel 5 at the driving gear side thereof.
  • shaft 2a or 2b is driven by the worm wheel 5 which is rotated by a worm 6 meshed therewith.
  • the worm 6 is mounted on a drive shaft 7.
  • a pair of drive shafts 7 are arranged on both sides of the roller system and a plurality of worms 6 are mounted on each of the drive shafts 7.
  • the worm wheels 5 are mounted so as to engage the right and left ends of the shafts on an alternating basis. Accordingly, the number of the right side worm wheels 5 is equal to that of the left side worm wheels 5.
  • FIG. 7 shows yet another embodiment of the invention where a roller pair 3a, 3b, having a sheet material 4 nipped therebetween are shown driven not only by gears la and 1b via shafts 2a and 2b, but also by gears 1c and 1d via shafts 2c and 2d, respectively.
  • roller shafts are driven by any type of driving means, i.e., the driving means need not be a worm or spur gear system, but can be any equivalent means such as frictionally engaged wheels, a belt drive, etc.
  • driving occurs on alternative sides of the upper and lower roller in a roller pair, on alternate sides of one roller of adjacent pairs of rollers or driving occur from both sides of both rollers in a single roller pair. It will be clear to one skilled in the art that systems could be used where various embodiments as described above are combined in a single processing line.
  • each roller pair unit comprising rollers on opposite sides of said sheet material, rotating in opposite directions with reference to each other and frictionally driving said sheet material bynipping said sheet material between the two rollers of said roller pair units to pass said sheet material from roller pair unit to roller pair unit
  • thevimprovement comprising: each of said roller pair units being driven from one side only with each roller of said roller pair units carrying a gear to the same side thereof and in mesh with one another with one roller ofa given roller pair unit driven by the other, the axes of said rollers for each roller pair unit defining a plane which is at right angles to the plane of sheet material moving between the rollers of the roller pair units, drive shafts extending along the direction in which the sheet materials are fed on each side of the roller pair units, gears carried by said drive shafts at locations corresponding to given roller pair units and in mesh with a gear carried by one of said rollers for each roller pair unit, the improvement wherein: each of said roller pair units
  • said gears carried by said drive shaft comprise worms in mesh with the gear at the end of said given roller for each roller pair unit.
