Definitions

  • the invention relates to a device for spreading sheets and the like in preparation to their being ironed in an ironing machine.
  • an article such as a sheet
  • the leading edge of the article is fed between the ironer rollers and the trailing part is drawn on thereby. Steps must be taken to ensure that the trailing part of the article is substantially free from rucks and folds before passing between the ironer rollers.
  • the present invention seeks to provide an improved spreading device through which the trailing part of the article may be drawn as it is fed to the ironer.
  • the device may be used if the sheet is fed by hand to the ironer but is particularly suitable for use in conjunction with an automatic feeding machine, particularly of the kind described in my copending patent applications Nos. 550,439, filed May 16, 1966 and 612,386, filed Jan. 30, 1967, where the spreading device of the present invention would take the place of the air-box spreading arrangements described.
  • a device for spreading a sheet or the like which is fed forwards with its centre on a centre line comprising two pairs of endless bands arranged symmetrically, one pair on either side of the centre line, each band having an inner run which faces the inner run of the other band of the pair, means for driving the bands in contra-rotating fashion, the inner runs having a component of movement outwardly from the centre line, and means for periodically moving a substantial length of the inner runs of each pair of bands together and apart, the arrangement being such that respective sides of the sheet are drawn between the inner runs and spread symmetrically sideways thereby, the periodic movement of the inner runs providing a periodically varying grip on the sheet.
  • the bands are all driven at the same peripheral speed and the periodic movements of both pairs of bands are synchronised and in phase. This is a particularly simple way of ensuring that the sideways drag of the two pairs of bands on the sheet is balanced and the spreading is symmetrical, even at relatively low periodic frequencies.
  • the periodic movement of the inner runs with respect to each other may be effected in a number of ways.
  • the bands, with their respective carriers may be moved bodily towards and away from each other or means may be provided within one or each .band of each pair for deflecting a substantial length of the respective inner run transversely towards the other inner run of the pair.
  • a pair of pivoted rocker arms arranged one at each end of the inner run so that the band slides over the ends thereof, simultaneous actuation of the two rocker arms swinging the ends towards the other belt of the pair and thereby moving substantially the whole of the inner run towards the other belt against the tension in the belt.
  • a mechanical linkage is provided between the drives for all the bands to ensure that they are all driven at the same peripheral speed, and preferably the rocker arms for the different pairs of bands are mechanically linked together to ensure synchronous operation.
  • the bands have raised pads spaced apart on their outer surfaces, the arrangement being such that the pads on the facing inner runs of the belts co-operate with each other to engage the sheet when the inner runs are brought together.
  • the spaces between the pads allow room for the convolutions in the sheet as they are progressively spread out.
  • the bands are disposed on either side of the centre line extending perpendicularly thereto, although if it is desired to apply more longitudinal drag, to the sheet the belts may be offset slightly from the perpendicular rearwardly from the centre.
  • FIGUREI is a perspective view of a laundry feeding machine incorporating the invention.
  • FIGURE 2 is a plan view of the spreading device of FIGURE 1;
  • FIGURE 3 is a perspective view of one of the rocker arms of FIGURE 2.
  • FIGURE 1 shows the conveyor of a feeding machine of the kind described in the aforementioned copending applications.
  • the sheet 1 is laid by a pair of grips (not shown) onto a forwardly moving conveyor 2 with its centre on a centre line 3.
  • the conveyor 2 draws the leading part of the sheet forwards in the direction indicated by the arrow and the trailing part of the sheet is drawn over a feed roller 4.
  • the spreading device in accordance with the invention is provided immediately beneath the feed roller and comprises four endless bands 5 arranged in two pairs, one pair on either side of the centre line 3.
  • the bands rotate continuously around vertical pulleys 6a and 6b which are all 4" diameter and which are rotated at about rpm.
  • FIGURE 2 is a schematic plan view of the spreading arrangement and shows means (for convenience not shown in FIGURE 1) for reciprocating the inner runs IF of the foremost bands transversely towards and away from the inner runs IR of the rear-most bands.
  • Means for convenience not shown in FIGURE 1 for reciprocating the inner runs IF of the foremost bands transversely towards and away from the inner runs IR of the rear-most bands.
  • Mounted within each of the foremost bands near the pulleys therefor are two right-angle rocker arms 13 pivoted on beams 26 about vertical pivots at 24 and having ends 25 which bear against the inside of the inner runs IF.
  • a tension member in the form of a link rod 16 couples the four rocker arms together, being pivoted to each, and movement of the link rod across the machine to the right rocks the rocker arms about their pivots to project the inner runs IF against the tension in the belts transversely towards the inner runs IR.
  • Rod 16 is reciprocated by the action of a cam 18 fixed to rotate with the left-hand pulley 6a and cut so that there is one complete reciprocal movement of the bands for every revolution of the pulley.
  • a cam 18 fixed to rotate with the left-hand pulley 6a and cut so that there is one complete reciprocal movement of the bands for every revolution of the pulley.
  • the bands carry raised pads 19 of felt 6" in length and spaced 2" apart.
  • the pads on runs IF and IR are arranged to cooperate with each other so that when the runs are together the pads grip the sheet but the spaces between the pads allow the convolutions in the sheet to be drawn out progressively.
  • FIGURE 2 illustrates the nature of the reversing drive employed between pulleys 6a and 6/). For convenience only that for the righthand pulleys is illustrated, shown comprising a chain 20 which is driven from the motor 7 via a sprocket 21 and which drives sprockets 22 and 23 mounted respectively on pulleys 6a and 6b in the manner shown.
  • FIGURE 3 shows in detail a rocker arm 13, which has the pivot 24 and the end 25 in the form of hollow tubes 24 and 25 welded together with a spacer 26, tube 24 constituting the shaft for a pivot axle (not shown) and an arm 27 being at its end coupled to the rod 16.
  • the pads 19 may be formed integrally in a thermoplastic belt, in which case suitable gripping profiles can be moulded in.
  • the tension member in the form of pushrod 16 may be replaced in the interests of light weight by a tension member in the form of a wire acting in tension against a return spring and fixed to the rocker arms.
  • the mark/space ratio of the engagement and disengagement of the bands may be varied by suitably cutting the cam and the speed of reciprocal motion in relation to the belt speed may be different from that shown by suitably gearing the cam to the pulley.
  • a device for spreading a sheet or the like which is fed forwardly with its center on a centerline of the device, the device comprising two pairs of endless bands positioned symmetrically with respect to said centerline,
  • each band having an inner run which faces the inner run of the other band of the pair, means coupled to said bands for driving the bands in contra-rotating fashion, the inner runs moving outwardly from the centerline, and means engageable with the inner runs of one band of each pair for periodically moving a substantial length of the inner runs of each pair of hands together and apart, whereby respective sides of a sheet positioned between the inner runs are drawn between the inner runs and spread symmetrically sideways, the periodic movement of the inner runs together and apart providing a. periodically varying grip on the sheet.
  • a device as claimed in claim 1 in which said means for moving the inner run comprises a pair of rocker arms pivotally mounted within one band of each pair, one at each end of the inner run with the band sliding over the free end thereof, and means associated with each pair of rocker arms for rocking the arms about their pivotal mounting to swing said free ends thereof towards and away from the other belt of the pair so as to give said periodic movement.
  • rocker arms for both pairs of bands are mechanically ilnked to move all the rocker arms together.
  • a device as claimed in claim 4 wherein the means for rocking the rocker arms comprises a tension member coupled with all the rocker arms and spring loaded in one direction and a cam engaged with the tension member for moving the tension member periodically in the other direction to rock the rocker arms.
  • each of the bands have raised spaced apart pads on their outer surfaces, the pads on the facing inner runs of the belts cooperating with each other to engage the sheet when the inner runs are brought together.
