Definitions

  • the present invention relates to an apparatus for packaging loose granular material in bags or sacks which has been developed especially for thebagging of cereals, grains, feeds and other commodities of a like nature which have heretofore been bagged on auger packing machines.
  • the objects of the invention are to provide a machine for the purpose which will alleviate many of the disadvantages inherent in the use of existing machines.
  • One of the advantages of the present invention is the elimination of much of thedust which is created by existing types of machines, the bagging operation taking place in a closed casing from which the air is withdrawn and delivered to a dust separator located outside of the mill.
  • Another object is the attainment of greater compactness so that bags or sacks of any standard weights are substantially smaller. This is due to the fact that air is withdrawn from the chamber about the bag which causes the contents of the bags to be tightly packed.
  • Fig. 1 is a partial sectional view through the -machine with the casing closed, the outline of a. full sack being shown in dotted lines in this view.
  • Fig. 1a is an enlarged detail section at the point where the bag is clamped between the casing. and the mouth of the hopper.
  • Fig. 2 is a section through the bag support on theyline 2-2 of Fig. 1.
  • Fig. 3 is a horizontal section on the line 3-'-3 of Fig. 1.
  • Fig. 4 is a section on the line 4-4 of Fig. 3.
  • 'Fig. 5 is a view similar to Fig. 3, but showing the casing open.
  • a device which weighs out a charge of the grain.
  • Such devices arewell known in the art and the location of one of these devices is shown at I in Fig. 6.
  • Such a device functions to discharge a supply of the commodity for one bag and is usually provided with a manually operated discharge which empties the weighed contents of the device I into a feed chute or hopper 2, at the lower end of which is clamped the bag B.
  • the upper end of the hopper is not closed about the measuring device so that air may flow into the. upper end of the hopper.
  • Bags for granular commodities of the type which this machine is designed to handle are usually made. of heavy, coarsely woven fabric which is pervious to air. Surrounding the bag is a casing 4 which is provided with sealing means to be described which holds the bag in position to receive the charge and also provides an airtight seal about the mouth of the bag. In Fig. 6 the bag is shown in about the position it assumes before the weighed charge is delivered by the device I.
  • the casing is usually in two parts which close about the bag and this casing is connected to a source of vacuum here indicated as a conduit 6 which leads to a suction fan I from which the air evacuated from the casing is discharged in the conduit 6 and thence to a dust separator here shown as a separator 9 of the centrifugal type.
  • a source of vacuum here indicated as a conduit 6 which leads to a suction fan I from which the air evacuated from the casing is discharged in the conduit 6 and thence to a dust separator here shown as a separator 9 of the centrifugal type.
  • the discharge end of the chute 2 is provided with a band [0 about which is located a circular rib l2 by which'the upper end of the bag is clamped to the mouth of the chute. 7
  • the stand or support for the casing 4 This comprises an upright l 4 rising from a base plate l5 and a vertical shaft [6, the lower end of which is mounted on the plate l5 and the upper end of which is fixed to the upright [4 by a bracket II.
  • the shaft [6 is the pivot about which the two parts of the casing move from the open position shown in Fig. 5 to the closed position shown in Fig. 3.
  • Each section of the casing is shown as a semicircular or semi-elliptical shell 20 or 21 having a '34 is a cradle-like bag support 10.
  • each casing section is provided with two spaced ribs 26 and 21, which, when the casing is closed, fit above and below the rib [2 on the lower end of the chute.
  • a soft rubber gasket 28 which is of a sufiicient depth so that when the casing is closed about the mouth of the chute the mouth of the bag will be firmly held in position and the passage occupied by the bag will be air-sealed.
  • Fig. 1a shows this feature in detail.
  • each casing section is provided with a flange 30 to the upper side of which is secured a rubber gasket 32, the inner edge of which may project slightly beyond the flange 30 so as to make an airtight seal with the outer surface of an outlet pipe 34 projecting above a base 35 and connected to the duct 6.
  • the two-part casing 2fi-2i is opened and closed about the bag by the two operating links 40, one end of each link being pivotally connected to a lug 4
  • the operating links extend rearwardly of the machine where they are forked and pivotally connected to a cross head 44 which is slidably mounted in a guideway 45 fixed to the upper surface of a platform 46.
  • the platform 46 is secured to the rear face of the upright 14 and is supported at its outer end by the diagonal brace rod 48.
  • the cross head 44 is attached to the rod of a piston 50 located in the cylinder pivotally supported on a bracket 52 fixed on the upper surface of the platform 46.
  • Pressure lines 54 lead from opposite ends of the cylinder to a valve unit 55 located at a point convenient to the operator as he stands at the front of the machine.
  • Valves within the unit 55 and operated by pedals 5t control the admission and exhaust of fluid pressure from opposite ends of the cylinder 5
  • rods 60 are provided which are pivotally mounted at their outer ends in lugs 6
  • the other ends of the rods 60 are slidably received in guides 63 depending from and swivelly mounted in the ends of cross arm 65 attached to the underside of platform 46.
  • a coil spring 66 is located about each rod, the forward end of each spring lying against a collar 61 on the rod near the lug 6 I. As the casing sections move toward open position, the coil springs are compressed between the guides 63 and the collar 61.
  • Spring locking means is provided for holding the sections of the casing together at the moment that the casing is closed.
  • a simple form of lock for this purpose is illustrated in the drawings as a spring held latch 68 located on the section 2
  • the pivot 13 is located at one side of the center of 4 the cradle so that the cradle normally assumes the horizontal position shown in full lines in that view and rests upon a stop 16.
  • the cradle may be tilted downwardly as shown in dotted lines in Fig. 2 so that the filled bag may be more easily removed from the machine, but when the bag is removed thecradle returns to its'horizon'tal position.
  • the suction fan I may be run continuously.
  • the casing being open, the operator inserts a bag mouth over the band III, the mouth usually being stretched sufliciently so that the empty bag will be suspended on the rib l2.
  • the operator now steps on the appropriate treadle 56 and the casing sections 20 and 2
  • the lower end of the casing is also sealed about the pipe 34'.
  • the bag being empty at this moment will act as a partial closure for the lower end of the hopper and because air is thus prevented from flowing freely into the top of the casing, the air pressure within the casingwill be substantially reduced. At the same time, the bag will belly out due to the reduced pressure in the casing so that the charge may fall freely to the bottom of the bag.
  • the contents of the bag therefore leave a substantial area around the exposed top of the bag through which air may flow to relieve the vacuum within the casing about the bag.
  • the operator now releases the latch 68 and steps on the proper pedal 56 and the casing opens up.
  • the interval required for the operator to release the latch and operate the casing opening means is sufficient so that the differential between the inside of the casing and the outside air is not sufiicient to prevent the casing from opening freely.
  • the opening of the casing releases the top of the bag and the bag settles on the cradle 10 from which it may be removed.
  • valve mechanism which opens and closes the casing may also be employed to start and stop the fan, mechanism to accomplish this purpose being readily designed.
  • a machine for filling bags with grain or the like comprising a chute for delivering acharge of grain, means to suspend a bag from the chute with the mouth of the bag surrounding the 'deliv ery end of the chute, an expansible casing, sealing means around the upper edge of the casing to grip the mouth of the bag when the casing is contracted about the delivery end of the chute, means to close the casing around the bag while it is suspended from the chute, said casing when closed forming a chamber about the bag, and means to evacuate air from the interior of the chamber while the bag is receiving the charge of grain.
