  • FIG. 5 is a section on the line lV-IV in FIG. 4, and
  • FIG. 6 is a section through part of an air bed, with a 'modified arrangement of air ducts.
  • a roller conveyor for conveying flat sheets lying in a horizontal plane consists of three successive conveyor sections 11a, 11b and 110.
  • the upstream section 11a and downstream section 11c are both similar and consist of a number of parallel driven rollers 12 extending across the full width of the conveying path.
  • the rollers rotate about horizontal axes and are provided with a plurality of tyres 13 at spaced positions along their length.
  • the middlesection 11b has similar rollers 14 extending across half theconveyor.
  • the other half of the conveyor consists of an air box 15 normally lying flat with its upper surface slightly below the upper peripheries of the tyres 13.
  • a sheet supported on the air bed over the box 15 is normally substantially coplanar with sheets lying on the tyres 13.
  • the inner edge 16 of the air box 15 is spaced slightly to one side of the centre line of the conveyor and both sides of the air box extend parallel to the direction of travel. of the glass which is indicated by the arrow A' in FIG. 1.
  • the light source and detector 22 is positioned at one side of the conveyor above the rollers 12..
  • the reflector 23 is positioned half-way across the conveyor below the level of the rollers 12. The light source directs light towards the reflector and if no glass sheet is present between them, light is reflected back to the detector giving a signal indicating the absence of a sheet.
  • the air box consistsof a rectangular hollow enclosure having a plurality of gas outlet passages 24 passing perpendicularly through the upper wall 25 of the air box.
  • the gas outlet passages 24 may, however, be so inclined that gas emitted therethrough tends to urge a sheet supported on the gas cushion towards the datum belt 18, eg. the passages may be at an angle of about to the upper wall 25 of the air box.
  • FIG. 6 Such an arrangement is shown in FIG. 6 in which similar reference numerals are used.
  • the interior of the box is subdivided into four sections by partitions 26, 27 and 28. Each section of the box is supplied with air under pressure through an inlet pipe 29. Air is fed into the box at a sufficient rate for the air jets escaping through the outlet passages 24 to provide a gas cushion to support a sheet passing over the upper surface of the air box. As shown in FIG. 3 the air box is pivotally mounted about a horizontal axis extending through the upper corners 30 of the box adjacent the edge 17. The lower surface of the inner edge 16 of the box is supported by a pneumatic jack device 31 sothat the inner edge 16 may be raised to the position shown in dashed lines in FIG.
  • the jack device is arranged to tilt the box through an angle of 5 when actuated.
  • the jack device 31 is mounted on a rigid support 32 and the piston rod 33 projecting from the jack device acts through a pivoted arm 34 to raise or lower a connecting rod 35 secured to the lower surface of the inner edge 16 of the box 15.
  • the jack device'31 consists of a double acting piston and cylinder, the opposite ends of the cylinder having separate air inlet pipes 36 and 37. Each of these pipes incorporates a flow regulator 38.
  • the two regulators 38 are connected to a main source of compressed air 40 through a solenoid valve 39.
  • the solenoid valve 39 is connected via two control lines 41 and 42 through a time control unit 46 to the optical sheet detector 22.
  • two glass sheets travel side-by-side along the upstream section 11a of the conveyor.
  • These two sheets which may have been formed by centre splitting of a larger sheet, will have a slight lateral separation a1- ready-due to use of an earlier separating mechanism. This may for example be as described in commonly assigned co-pending Application Ser. No 298,385, filed Oct. 17, 1972, for CONVEYING APPARATUS".
  • the sheet on the left hand half of the conveyor is detected by the optical detector 22 and an appropriate signal is fed to the control unit 46.
  • the sheet on the left hand half of the conveyor passes onto the air bed as shown by the plate marked 43 in FIG. 1.
  • the sheet on the right hand half of the conveyor continues on the rollers 14 past the air box 15.
  • the control unit 46 provides an adjustable time delay so that the solenoid valve 39 and thereby the jack device 31, is operated when two-thirds of the sheet has passed onto the air box 15.
  • the jack device then causes the air box to be tilted with its inner edge 16 moving upwards.
  • the plate 43 slides downwards towards the edge 17 while its momentum continues to move it forwardly towards the downstream section 11c of the conveyor.
  • the plate will pass along a path substantially as indicated by the line 44 in FIG. 3 until the plate lies against the belt 18 which provides a datumsurface adjacent the edge of the air box 15.
  • the timing control unit 46 is so adjusted that the jack device 31 lowers the air box back to the original position before'the leading edge of the 1 glass plate leaves the air box 15. In this way, the sheet when leaving the air box passes smoothly ontothe surface of the downstream section 1 1c of the conveyor. In the meantime, the sheet on the right hand side of the conveyor has also passed ontothe downstream section of the conveyor. The two sheets then continue to move together with a much greater lateral separation than was present on the upstream section of the conveyor. The sequence of events causing the lateral separation may be repeated for subsequent sheets arriving at the air bed. 7
  • the above described example is particularly suitable for providing a second stage oflateral separation in the process of cutting glass ribbon into separate sheets and providing the desired separation and alignment of sheets prior to arriving at a stacking station.
  • the momentum of the sheet passing across it may be sufficient to carry it across the air bed and onto the downstream section of the conveyor. This movement can however be assisted by the driving movement of the datum conveyor belt 18.
  • the gas ducts in the air box may be so inclined that the sheet is urged towards the datum belt 18 which can assist in holding the sheet against the belt.
  • the lateral separation is selectiv'ely controlled by actuation of the jack device 31.
  • each air box has its own datum means in the form of the conveyor belt 18.
  • the arrangement shown in FIG. 4 is the same as that described with reference to FIG. 1 except for the useoftwo air boxes rather than one.
  • the two boxes 15a and 15b are separated along their inner edges 52 and 53 so that both inner edges may be raised simultaneously to tilt the air boxes and cause the two sheets 50 and 51 to move outwardly in opposite directions.
  • the tilting mechanism which may be operated by a signal from a single sheet detector located in front of one of the air boxes, is shown in more detail in FIG. 5.
  • Each hollow box is mounted on a frame 55 having a pivot mounting 56 on a support 57.
  • the inner edge of each frame 55 normally rests on a stop member 58 such that boxes lie in a common horizontal plane.
  • Pivotally connected to the inner edge of frame 55 is a push rod 59 connected via a bell crank lever mechanism 60 to a pneumatic jack 6].
  • a counterweight 62 is connected on an arm 63 forming part of the lever mechanism 60 to counterbalance the weight of the air boxes.
  • Both pneumatic jacks 61 are connected to a common pneumatic supply so that both jacks are operated simultaneously to raise or lower the inner edges of the air boxes. The angle of tilt is about 5. Air to form the air cushion is supplied to both boxes through a common supply pipe 64, and flexible hoses 65 secured to pipes 66 adjacent the pivotal mounting 56.
  • a sheet of glass which has been scored along its centre line by a known form of scoring device schematically shown at 70 is fed centrally along the conveyor towards the air boxes which are lying horizontally.
  • the boxes are tilted and both halves move outwardly in opposite directions. Both halves move forwards on the air cushions and in controlled lateral positions due to the belts 18 as described with reference to FIG. 1.
  • the snapping may be effected by known snapping devices such as the rollers 67, 68 and 69 shown in FIG. 4.
  • the scored sheet may be fed over the air boxes so that the central score line lies over the space between the inner edges of the air boxes whereby when the boxes are tilted, the sheet is flexed about the score line so as to snap the glass and open up the out along the score.
  • the two smaller sheets so produced by splitting the relatively large sheet then move outwardly in opposite directions as previously described. In this way, the snapping and lateral separation can both be effected by the use of the tilting air beds alone.
  • a mechanical device such as a spring loaded finger may be positioned in the path of the advancing glass to detect the leading and/or trailing edges of successive sheets.
  • Apparatus for effecting a sideways shift of a forwardly travelling sheet member comprising conveyor means for conveying a sheet member lying in a gener ally horizontalplane in a forward direction, said conveyor means comprising upstream and downstream sections in the same horizontal plane, support means comprising a table provided in the conveying path, between the upstream and downstream conveyor sections, said table having two opposite edges extending along the conveyor path with pivotal mounting means adjacent one of said edges, said table further having ducts therein for the emission of gas through a surface thereof to provide a gas cushion on which the sheet member can be supported when passing over the table, lifting means, selectively operable to raise the other edge of the table and thereby tilt said table about said pivotal mounting means in a direction transverse to said forward direction between a horizontal position substantially coplanar with the conveyor means and a position inclined to the horizontal, for moving said sheet member in a direction transverse to said forward direction while the member is supported on the gas cushion, and datum means located adjacent said one edge of the table to arrest lateral movement and thereby locate at
