INVENTOR ALLEN WMERRELL, 2412 25 United States Patent() 2,898,721 BAG FILLING MECHANISM Allen W. Merrell, Detroit, Mich., assignor to Sattley Company, Detroit, Mich, a'corporation of Michigan Application November 23, 19'55,-Serial No. 548,718

This invention relates to mechanism for filling bags and while not limited to the bagging of any particular material or articles, it has been developed more particularly for the bagging of cylindrical objects, and particularly to those of considerable weight for size, such as wrapped stacks of coins. For this purpose it is necessary to hold the mouth of the bag open or distended so as to permit ready loading of the articles. As shown this may be accomplished by the use of an open ended chute which may extend well into the bag and through which the articles or material may be fed thereinto. It may also be desired to fill the bag while the bag is supported on its side on a platform so that the Weight of the bag and contents may be carried thereby and avoid any excessive pressure of the articles or objects on the botom of the bag which might result with the bag in a more vertical position and the articles or objects on the bottom of the bag which It is also desirable to support the bottom of the bag independently of the support for the chute so as to maintain the bag in position on the support against any pressure exerted thereon by the articles or objects fed thereinto while the bag is being filled.

Means also may be provided to obstruct reverse flow of the articles or objects outwardly from the bag, and this may be constructed and arranged to position the articles in a predetermined manner.

In order to facilitate removal of the chute from a filled bag, the support for the bottom of the bag may be so mounted as to be movable out of contact therewith, whereby the open end of the bag and the chute may be tipped up and the chute removed from the bag and the bag mouth closed while the bag and its contents remain supported. When this has been accomplished the filled and closed bag may be removed from the support and replaced by an empty bag with the chute extending into it in position for the empty bag to be filled.

For a complete understanding of this invention, reference may be had to the accompanying drawings in which:

Figure 1 is a somewhat diagrammatic perspective view showing an empty bag with a chute extending thereinto supported on its side and with the support for the bottom of the bag in position, the parts being arranged in filling relation to a device for feeding wrapped coins into the outer end of the chute.

Figure 2 is a horizontal sectional view of the same showing the chute and bag with one layer of wrapped coins therein.

Figure 3 is a view similar to Figure 2, but showing a portion of a second layer of wrapped coins in position within the bag.

Figure 4 is a front elevation showing the bag and chute upwardly tilted.

Figure 5 is an exploded perspective view of the chute and the bag in vertical position.

Figure 6 is a view drawn to a larger scale of a latch mechanism for holding the bag bottom abutment in either of two positions.

on its side. An abutment 3 is carried by the support 1' and isshown as hinged for motion between a position shown in Figures 1, 2, and 3 where it engages the bottom 4 of the bag and holds the bag against motionexerted fromthe pressure of articles being fed thereinto, and an inoperative position showninFigure 4 as will later appear. In order that'the bag may be filled, its open end should-beheld distended and for this purpose there is illustrated an open ended chute 5, which may be inserted therein. Where wrapped coins are beingemployed, this chute "5 may besubstantially rectangular in cross section and with'an internal width slightly greater than the length "of thepa'ckage or 'roll of coins to befed thereinto. 'It will be recognized that these rolls vary in length, depending upon the denomination of the coins enclosed and the number of coins in each, and it is preferable to employ a series of chutes, one of which has a width suitable for receiving freely a roll of coins of the chosen denomination arranged transverse thereto.

The wrapped or rolled coins may be fed into position in front of the open end of the bag and the corresponding end of the chute by any suitable means such as a slideway 6 which delivers the wrapped rolls of coins from a suit-- able packaging machine, a portion of which is shown at 7. The particular type of wrapping machine is no part of the present invention and hence will not be further described, it being sufiicient to state that it includes a rotary disk 8 to one end of which is pivotally mounted a lever 9. This lever 9 is fulcrumed at 10 and its opposite end is pivoted at '11 to a plunger 12 which engages back of each wrapped roll of coins as it is delivered from the slide 6 and is moved axially to feed wrapped coins into the adjacent end of the chute 5.

A stop member 15 may be positioned to receive the rolls of coins as they drop from the end of the slide 6 and position them in proper relation to the open outer end of the chute 5. As shown best in Figures 1, 2, and 3, the forward end of this chute may be partially closed off by a wall member .16 in which may be mounted means such as a latch member 17 having a beveled end .18 positioned to be engaged by the rolls of coins and to be retracted against the pressure of a spring 19 to permit the rolls of coins to pass by and into the outer end of the chute 5. Cooperating with this latch 18 is a rise 20 in the form of a bevelled lug in the bottom of the chute, these two parts obstructing return motion of the articles from within the chute against the direction of feed of the articles into the chute. The member 20 also presents a laterally straight upwardly inclined front face which tends to aline the rolls in parallel relation and to guide those more recently entering into the chute end upwardly and over preceding layers of the rolled coins as illustrated in Figure 3.

T he bag being positioned on the chute in the position shown in Figures 1, 2 and 3, the desired number of rolls of coins are fed thereinto past the obstructing

means

19 and 20. The abutment 3 may thereafter be turned out of position to engage the bottom of the bag, permitting the bag and the chute to be tilted upwardly as shown in Figure 4. To facilitate this action, the abutment 3 is hinged to the support 1 and the hinge connection includes a disk member 21 carried by one of these parts and a spring latch 22 carried by the other, engageable selectively in either of a pair of angularly spaced notches 23 in the disk 21 so that the abutment may be latched in either the bag-engaging position shown in Figures 1 to 3 or may be turned downwardly in substantial alinement with the upper face of the support 1 as shown in Figure 4 and in full lines in Figure 6.

When the abutment is moved into this lowered position,

3 the bag and the chute may be tilted upwardly, a handle 25 attached to the chute outwardly of the mouth of the bag being employed if desired to facilitate this action. This permits the rolls of coins to pass down into the bag and the chute 5 to be withdrawn therefrom so that the filled bag may be closed and removed from the platform after which an empty bag with the chute extended there,- into may be placed in position for a succeeding filling operation.

From the foregoing description of an embodiment of this invention, it should be evident to those skilled in the art that various changes and modifications may be made therein without departing from its spirit or scope.

I claim:

In combination, a horizontal support on which a bag to be filled may be laid on its side, an abutment hinged to said support for engagement with the bottom of the bag, spring latch means releasably holding said abutment alternatively in a vertical operative position or in a horizontal position, and an independent open-ended chute extending into the bag to hold the bag distended, the open end of the chute within the bag pressing the bottom of the bag against said abutment, a bevelled lug mounted transversely within said chute near the other end thereof, said lug presenting an inclined face to objects entering the chute, and means for pushing successive objects into said chute and toward said lug.
