Definitions

  • the present invention relates to laundry equipment and more particularly to a spreader and feeder machine for unfolding large sheets of fabric such as bed sheets prior to the feeding thereof into a subsequent machine such as a drier.
  • the machine which, as aforesaid, is used for large sheets of fabric, such as table cloths and other coverings of substantial size, is also adapted to remove wrinkles in the material before feeding thereof into the next machine thereby eliminating any manual handling.
  • the machine according to the invention is essentially characterized in that it generally comprises an upstanding frame; a work feeding mechanism at the upper end of the frame for receiving one end of a sheet to be treated; the mechanism forcing displacement of the sheet from front to rear of the frame at a predetermined speed, and conveying means forwardly of and below said feeding mechanism, travelling in the same direction and at a speed greater than said predetermined speed to force the remainder of the sheet, not engaged by said feeding mechanism, inwardly of the frame and in hanging condition from the mechanism.
  • the conveying mechanism includes spreader and straightener rollers having helically arranged ribs on their surfaces, disposed thereon from the center to the roller ends, the said ribs when the rollers rotate causing the fabric to be laterally stretched towards the edges thereof and flattened out. Also friction of the rollers on the opposite faces of the fabric stretches it longitudinally.
  • FIGS. 1, 2 and 3 are diagrammatic elevation views of the machine of the invention in three different stages of operation.
  • FIGURE 9 is an end view of the spreader and straightener smoothing rollers of FIGURE 8.
  • reference numerals 1 and 2 designate the lateral upstanding frame of the machine on which are mounted the bearings carrying the various rollers to be discussed hereinbelow.
  • Reference numeral 3 designates a conveying trolley supplying the sheets leaving a wringing machine to the input of the device of the invention.
  • the upper lefthand corner of the machine illustrated in :FIGURES l, 2 and 3 is in direct contact with the input of a drier (not shown).
  • Reference numeral 4 indicates, in dotted lines, a sheet, the evolution of which through the machine will now be followed hereinbelow.
  • Driving roller 9 is mounted, in a conventional manner, on a resiliently adjustable support allowing adjustment of the pressure between rollers 5 and 9.
  • the above described apparatus forms the work feeding mechanism.
  • the selvedge of a sheet is brought between rollers 5 and 9 which rotate in the directions indicated by the arrows drawn concentrically about the said rollers. Once gripped between the said driving rollers, the sheet carried by belts '7 and roller 6 is displaced at a constant speed in the direction of arrow 13, without being able to move backwardly.
  • roller 14- rotates more rapidly and in the opposite direction relatively to roller 6.
  • its surface rubs on the lower face of the sheet and exerts a force opposing the direction of displacement of the sheet in the Zone referred to by numeral 24.
  • conveyor belts 20- are displaced in the direction indicated by the arrow, the sheet 4 adopts successively, between the rollers 14 and 17, the various positions illustrated at 4a, 4b, 4c.
  • roller 17 rotates at a speed substantially equal to that of roller 14, the sheet very soon adopts the position illustrated in FIG- URE 2 at 4d, i.e. it has unfolded over a length which is substantially greater than that by which the sheet has advanced between the conveyor belts 7 and 10.
  • rollers 5 and 9 progressively raises the entire sheet between the belts 7 and 10, despite the opposing action of the friction developed by the spreader and straightener rollers, and an increasingly larger portion of the said sheet is engaged within the drier.
  • the speed of the fabric through the drier should be higher than the speed between driving rollers 5 and 9 of the work feeding mechanism, the object of this being to ensure that there will always be sufiicient tension in the sheet between the spreader and feeder machine and the drier.
  • the part of the sheet which passes last into the spreader and feeder machine has left rollers 5 and 9, it is then only maintained between the conveyor belts 7 and 10, and its speed is then that imparted by the rollers of the drier. Under these circumstances, the sheet slips between the set of belts 7 and 10, and this stretches and smooths out the terminal hem of the sheet.
  • a machine designed in accordance with the arrangements just described has permitted the easy engagement, by two non-skilled persons, of approximately 300 sheets per hour coming directly from the wringer.
  • FIGURES 5 and 6 The embodiment shown in FIGURES 5 and 6 is similar with respect to the driving rollers.
  • This machine comprises only two spreader and straightener rollers 25 and 26 which are identical with spreader rollers 14, 15 and 16. These rollers also rotate in a direction such that they oppose the movement of the sheet between rollers 5 and 9.
  • roller 25 is mounted on a fixed pivot
  • roller 26 is mounted on a pivot 27 carried at the end of an arm 28 articulated about a fixed point 29.
  • the control for the displacement of arm 28 about pivot 29 is obtained by a hydraulic or pneumatic control means 30 acting at a point 31 of lever 28. Pivot 27 is thus able to describe an arc of a circle 32 and to return into the position illustrated in FIGURE 6 between the driving roller 6 and spreader roller 25.
  • the sheet 4 is first laid between the driving rollers, whereafter it is allowed to bear on the spreader roller 26.
  • the latter withdraws the sheet from trolley 3 and causes it to drop within the machine, where it is able to enter into contact with smoothing roller 25.
  • roller 26 then adopts the position illustrated in FIGURE 6, in such a manner that the sheet is stretched simultaneously longitudinally and laterally on its two faces.
  • FIGURES 7, 8 and 9 relate to a novel arrangement involving the use of special features common to the embodiments illustrated in FIG- URES l to 4 on the one hand, and FIGURES 5 and 6 on the other hand, this embodiment further comprising a special arrangement of certain of the spreader rollers used in the machine.
  • this embodiment permits easy adjustment of the transverse spreading force acting on the sheet by relative positioning of two separate cooperating spreader rollers.
  • a spreader roller which can be pivoted toward and away from a second roller by the provision of a lever and connecting rod mechanism actuated by a hydraulic or pneumatic control means, the said roller being thus adjustably movable in relation to said second roller; the rollers being so disposed that the ribs thereon are in interengaging relationship when in frictional contact with the fabric.
  • rollers 16, 18 and 19 and also conveyor belts 21 and 22 have been dispensed with, so that, in accordance with the operation of the machine illustrated in FIGURES 5 and 6, the sheet 4 can drop vertically as far as the foot of the machine while bearing on the spreader roller 15.
  • lever 36 and roller 35 can oscillate through a certain clearance angle, in such a manner that roller 35 can be brought closer to roller 15, the extent of which is being limited by an adjustable stop screw 40.
  • FIGURES 8 and 9 show the two arms of the lever assembly 36 supporting roller 35 in frictional contact with roller 15, the ribs of the said rollers intermeshing. At most, the ribs of one roller frictionally contact the smooth surface of the opposite roller. In practice, however, a sufficient distance must always be left between the said rollers, as a function of the incompressible thickness of the sheet hems.
  • a spreader and feeder machine for unfolding large fabric sheets such as bed sheets prior to the feeding thereof into a subsequent apparatus, said machine comprising:
  • lever means for holding said conveying means at one of the ends thereof and pivotable about the other end
  • said conveying means includes:
  • said machine further comprising:
  • a rearwardly and upwardly inclined endless conveyor located below said second conveying means travelling at a speed equal to said second conveying means but in a direction reverse that of said second conveying means.
  • leverage means for moving said third roller away from and into frictional contact with the roller of said conveying means.
  • a machine as claimed in claim 6 wherein the surfaces of the roller of said conveying means and said third roller are provided with helically arranged projecting ribs disposed thereon from the center to the roller ends and in such a way that, When the rollers are in frictional contact, they are in interengaging relationship.
