Definitions

  • the present invention relates to dispensers for sheets of paper and the like, of type comprising a tray adapted to hold a vertical stack of sheets and having oppo'site side walls defining an open end through which the sheets are withdrawn individually from the top of the stack, and a pair of sheet separator members having respective first portions which overlie the leading corners of the uppermost sheet in the stack and respective second portions which project downwardly from the first portions across the leading edges of the uppermost sheet and a number of the underlying sheets .
  • Dispensers of this type are disclosed, for example, in EP-A-0010280, GB-A-1135746 , GB-A-1185455 and GB-A-1206717 , and are intended mainly for use in photo ⁇ copying machines and the like, which withdraw- sheets of paper from the top of the stack with a predetermined pressure.
  • these trays In order to maintain the top of the stack at a constant level for withdrawal, these trays usually incorporate or are associated with resilient means which urge the stack towards the sheet withdrawal means of the machine - see, for example, EP 0031878, GB-B-2061231 and GB-B-2038289 •
  • the withdrawal means such as rubber rollers or suction pads, initially drag the top sheet of the stack against the separator members in order to buckle the sheet and separate it from the underlying sheet, and then remove the sheet in the feed direction-
  • the object of the present invention is to provide a dispenser for sheets of paper and the like, which avoids the drawbacks discussed above.
  • the invention also aims to provide a sheet dispenser adapted for use in a manual collation system.
  • the present invention provides a dispenser of the aforesaid type, in which the two said portions are carried by respective L-shaped parts of the separator members and are guided for vertical movement by respective key portions attached to or integral with the L-shaped parts and freely slidable in respective vertical keyway slots In the external surfaces of the two side walls, so that the weight of the separator members bears through the first portions upon the uppermost sheet of the stack in use of the dispenser.
  • a single sheet can be withdrawn from the tray simply by applying a finger to the central region of the upper- uppermost sheet just behind its leading edge, and moving it towards the open end of the tray to pull the sheet along due to the friction between the sheet and the finger.
  • the sheet As the sheet is withdrawn, its leading corners are restrained by the first and second portions of the separator members , causing the sheet to buckle slightly by arching in the regions- behind the leading corners and between the corners and the finger. Since the restrained corners are turned downwardly and bear upon the underlying sheet to hold it down, and the latter is prevented from moving towards the open end of the tray by the second portions of the separator members, the buckled uppermost sheet is separated from the underlying sheet.
  • the leading corners disengage themselves from the separator members and the sheet slides freely from the tray without entraining any of the underlying sheets, which are stil restrained by the separator members.
  • the dispensing tray of the present invention may be used individually for typing paper, information sheets and the like, but for use in a manual collating system to hold printed sheets which are to be put into sequence the tray should preferably be stackable with like trays.
  • the present invention provides a dispenser for sheets of paper and the like, comprising a tray adapted to hold a vertical stack of sheets and having opposite side walls defining an open end through which the sheets are withdrawn individually from the top of the stack, and a pair of sheet separator members having respective first portions which overlie the leading corners of the uppermost sheet in the stack and respective
  • the tray may have fixed dimensions for a specific sheet size, it preferably includes an adjustable back-stop so that one tray can accommodate a number of different common sizes of sheet.
  • the back-stop may be slidable longitudinally of the tray or , preferably, locatable at a number of discrete longitudinal positions along the base or the side walls.
  • Figure 1 is a perspective view of a dispensing tray for sheets of paper and the like, according to the present invention
  • Figure 2 is a view similar to Figure 1 showing the tray during the dispensing of a sheet
  • Figure 3 is a plan view of the tray of Figures 1 and 2 in its empty condition
  • Figure is a partial section of four interlocked, stacked trays of the invention, taken in the plane shown by the line IV-IV of Figure 3 ;
  • Figure 5 is a partial side view showing the stacking of three trays of the present invention.
  • Figure 6 is a partial perspective view of a detail of the tray of Figures 1, 2 and 3 on an enlarged scale, showing a separator member removed from the tray, and
  • Figure 7 is a view similar to Figure 6, showing the separator member in its raised position.
  • This tray 1 is made entirely of moulded plastics and comprises a base 3, two side walls 4 defining an open end 5 through which the sheets 2 are withdrawn from the top of the stack in use, an end wall 6, and an adjustable back-stop 7 facing the open end 5-
  • the " back-stop 7 is locatable in a number of discrete longitudinal positions between the side walls 4 by means of a pair of integral pins (not shown) which are engageable in an appropriate pair of holes of a longitudinal series of pairs of holes 8 in the base 3.
  • the adjustability of the back-stop 7 together with the chosen spacing between the side walls 4, enables the tray 1 to be adapted to accommodate different paper sizes, such as A4, foolscap and A5, with a clear ⁇ ance, typically 1-2 mm, between the walls 4 and the edges of the stacked sheets 2.
  • A4 foolscap and A5
  • a clear ⁇ ance typically 1-2 mm
  • the side walls 4 are formed with complementary tongues 9 and grooves
  • the opposite side walls 4 of the tray 1 are formed externally with complementary lateral hooks
  • sockets 12 Figures 1 and 2.
  • one side wall 4 has a hook 11 adjacent its upper edge near each end, and the other wall 4 has respective sockets 12 in corresponding positions.
  • the manner in which a number of trays 1 can be locked together side-by-slde and stacked is shown in Figure 4.
  • the sockets 12 are formed in the undersides of respectiv respective laterally outwardly projecting spacers 12A located at the upper ends of the grooves 10B , which are defined by respective pairs of vertical ribs 12B.
  • the tray 1 measures 330mm long, 210 mm wide, and 75 mm high internally.
  • the base 3 and side walls 4 have minium thicknesses of about 2 mm, and the back-stop 7 has a height of 60 ram.
  • each separator member 13 is moulded in plastics in a single piece and comprises an L-shaped part 14 extending from a key portion 15 freely slidable in the respective keyway slot 10A around the front or open end edge of the wall 4, and carrying respective first and second portions 16, 17 which project towards the other member 13.
  • the first portions 16 lie parallel to and rest on the top surface of the stack of sheets 2 at the leading corners of the uppermost sheet 2A, and the second portions 17 lie parallel to a plane containing the leading edges of the stacked sheets 2 and abut the. end portions of the leading edges of the uppermost sheet 2A and, say, ten of the underlying sheets 2.
  • the first and second portions 16, 17 of each separator member 13 comprise mutually-perpendicular tabs and the first portions 16 have smoothly rounded upper surfaces.
  • the sheets 2 are withdrawn individually from the tray 1 simply by applying a finger F to the centre of the uppermost sheet 2A just behind its leading edge, and moving the finger F towards the open end 5, in the direction of the arrow W in Figure 2, to draw the sheet 2A along by friction.
  • the sheet 2A As the sheet 2A is withdrawn, its leading corners are restrained by the first and. second portions 16, 17 of the separator members 13, causing the sheet 2A to buckle away from the immediately underlying sheet 2B. Since the restrained corners of the sheet 2A are turned downwardly and tend to hold the underlying sheet 2B down, and the latter is prevented from moving out of the open end 5 by the second portions 17 of the separator members 13, the uppermost sheet 2A becomes separated from the underlying sheet 2B.
  • the amount by which the separator member 13 impinge on the leading corners of the sheets 2 is not sufficient to crease or tear the uppermost sheet 2A as it is disengaged from the members 13, even when the sheet is of the flimsiest paper.
  • the rounded upper surfaces of the first portions 16 facilitates the smooth disengagement of the uppermost sheet 2A from the separator members 13. - 9 -
  • the separator members 13 When the tray 1 is to be loaded with a fre.sh stack of sheets 2, the separator members 13 are pushed upwardly in the keyway slots 10A to a raised position ( Figure 7) .
  • the keyway slots- 10A At their upper ends, the keyway slots- 10A have enlarged parts formed with steps 18 and the front edges of the side walls 4 have bevels 19, whereby the.key portions 15 of the separator members 13 rest on the respective steps 18 and the L-shaped parts 14 rest on the respective bevels 19, to support the separator members 13 in their raised positions.
