Definitions

  • This invention relates to the cleaning of sacks, bags or the like which have contained flour or pulverised materials and which may leave in the sacks or bags or adhering thereto a quantity of dry orpartly dry flour, offal or powder.
  • the invention is concerned with the treatment of sacks or bags of canvas, hessian, or calico in which for example flour or meal has been carried.
  • the invention consists in a machine for cleaning sacks, bags or the like in which the article is cleaned by portions thereof being exposed in succession to the action of beaters and brushes when in the form of a balloon-like loop or pneumatic cushion.
  • Figure l is a front elevation of the machine.
  • Figure 2 is a transverse horizontal section across the upper part of the machine.
  • Figure 3 is a vertical transverse section taken on the line 3--3 of Figure 1, and
  • Figure 4 is a fragmentary view illustrating the cleaning of a sack.
  • the machine comprises a boxlike frame or housing (1 having a removable top I) to allow inspection or repair of the internal parts.
  • the lower part of the housing or casing comprises inwardly sloping plates 0 of a funnel or hopper-shaped construction to allow of the discharge of the material.
  • a horizontal shaft 0! upon which is carried a pair of spider frames e, the arms of which frame are designed to carry the heater and brushing members as will be hereshaft is supported in the walls of the casing a upon suitable bearings 1, projects outside the casing and a driving pulley or other member g is fitted thereon to be belt or chain driven, or where desired the shaft may be directly driven by means of an electric motor for example.
  • Each set of beating and brushing appliances within the casing is arranged side by side upon the centre shaft 0! and each set comprises two metal tipped beaters hcf leather or the like arranged oppositely to one another and alternately therewith two brushes is opposite one another and combined with blades or vanes Z to exert a beating action on the air within the casing.
  • One such construction comprises a pair of beaters h preferably of leather, riveted at h by their inner ends upon one of the spider frames e, the outer end of the beaters being split as shown in Figure 2, and the tip of each split portion having riveted or otherwise secured thereto metallic plates m preferably of steel.
  • pairs of beaters are arranged on the-frames at 180 apart around the shaft and those on one frame relatively staggered with those on the other frame. Alternating with these two oppositely arranged sets of beaters there are arranged also 180 apart, the brushes k and the air beater vanes l assooiated therewith.
  • a horizontal slot oropening 11 Arranged in one side wall of the casing a (the righthand wall Figure 3) is a horizontal slot oropening 11 having a fixed guard and bracket plate 11. at each end, and within such slot is normally positioned and parallel therewith a roller 0 freely carried upon a spindle o the ends of which project beyond the roller ends. Links p, Figure 4, are attached at the projecting ends of the spindle o, and the spindleends are each inafter described.
  • the bushingq is under the influence of a spring s encircling a tail piece attached to the bushing q and one end of the spring constantly presses the bushing q in one direction against an adjustable stop q, whilst the other end of the spring abuts against a part of the plate 1".
  • the outer end of the link p is pivoted to one arm 15 of a double armed lever fulcrummed at t on the guard bracket n, the other arm u of the lever being connected to the upper end of a link 11., its lower end being pivoted to an actuating treadle '0 fulcrummed at v at the base of the machine.
  • a space is provided which allows a sack to be placed in the machine so that it may be cleaned.
  • the sack is threaded beneath the roller 0, passed upward across the slot 11. around the inner side of the roller and the upper part of the sack is held by the operator, see Figure 3.
  • the treadle o is now released so that the sack is pressed inwards into the casing and the beaters h and brushes k are caused to rotate in the direction of the arrow at a suitable speed, at about 400 R. P. M. by way of example.
  • the upper part of the sack is held by the operator and as the beat ers commence to rotate the operator feels the suction effect and he permits the upper portion of the sack to be drawn in to the machine as far as he considers necessary, which thereby causes the portion of the sack within the machine to form a balloon or loop, as indicated in Figure 4, this being due partly to the suction effect created by the beaters and the ballooning being produced by air being forced through the interstices of the sack which accumulates within the loop or balloon thus formed so that the beaters and brushes act as it were on a cushion of air, the balloon itself being resilient and allowing the beaters and brushes to successively pass in rapid rota tion and thus to be constantly agitated or bounced up and down as well as beaten and brushed.
  • the treadle 12 can be slightly relaxed to ease the grip of the retarder w 50 that another part of the sack can be drawn up through the slot and around the roller for treatment by the beaters and brushes.
  • the process of cleaning the sack is therefore carried out in successive stages and if necessary the sack may be passed through the machine again if it has not been sufficiently cleaned.
  • a sack or bag may be first passed through the ma-' chine so that the outside is treated and may be then passed through the machine a second time after being turned inside out, so that thorough cleaning may be ensured.
  • the machine may be modified in various ways, for example, the beaters may be increased in number than that described in the foregoing and the beater devices although usually made of leather, may be made of spring sheet steel or of stout rubber to allow flexing.
  • the brushing members may consist of ordinary hard bristles'having much the same stiflness as a clothes brush, but any form of bristle may be used depending upon the material forming the sack and the Work to be done.
  • the air beating blades or vanes I attached to the brushes may be either flat or may be corrugated, or if desired may be furnished with perforations, and means may be provided to radially adjust either the brushes, the air beater vanes or the metal tipped beaters.
  • the movement outwards of the roller may coincide with the placing of a safety plate across the slot.
  • the treadle v of the machine at the other side of the fulcrum.
  • a machine for cleaning sacks and like articles comprising a casinghaving a slot therein for the introduction of a loop-like foldedpart of the article to be cleaned, guide means for said article located within the slot, means in said casing operable upon the exterior of said folded part to subject the latter to a cleaning action, and means for releasably clamping one portion of said article in position adjacent one part of said slot, the remaining portion ofthe article being freely movable through another part of said slot.
  • A'machine for cleaning sacks and like articles comprising a casing having a slot therein for the introduction of a loop-like folded part of the article to be cleaned, guide means for said article located within the slot, means in said casin operable upon the exterior of said folded part to subject the latter to a cleaning action, and means for displacing said guide means to an inoperative position to facilitate'intr'oduction and folding of said article.
  • a machine for cleaning sacks and like 'articles comprising a casing having 'a slot therein for the introduction of a loop-like folded part of the article to be cleaned, guide means for said article located within the slot, means in said casing operable upon the exterior of said folded part to subject the latter to' a cleaning action, means for releasably clamping the article in position adjacent said slot, and means for simultaneously displacing said guiding and clamping means to inoperative position.
