' SORTING MECHANISM FOR CONFECTION WRAPPING'MACHINES.

Original application filed May 3, 1917, Seria1'No. 166,134. Divided and i i :1923. Serial No." 656,508.

ToaZZw/wmz'tmay0011mm; I U Be it known that I. JOSEPH Pnnor REM- INGTON. a citizen of the United States, residing at. Philadelphia, county of Philadelphia. and State of Pennsylvania, have invented certain new and useful Improvements in Sorting Mechanism for Confectionrapping Machines, whereof the following ,isa. specification, reference being bad to the accompanying drawings. 7 p

. The invention relates to improvements in sorting mechanism for use in. connection with wrapping machines such as shown and described in my priorPatentNo.1,352,629, dated September 14th, 1920, for improvements in machines for wrapping confections, and also in my co-pending application, Serial No. 166,134, filed May 3, 1917, for improvements in positioning and feeding mechanism for confection wrapping machines ofwhich the present application isa division. 1

I The subject matter of this inventionis more particularly directed to mechanism for automatically sorting the articles to be wrapped asthey are beingcontinuously fed to the wrapping devices. i J 5 In order to accomplish this purpose, the machine constructed according to my invention includes in connection with means for continuously feeding the confections,'devices for ejecting confections notproperly positioned for subsequent wrapping. p The structure ,by which I attain these ends will be best understood from the drawings, in which+ I I Fig. I, is a plan view of a portionof a wrapping machine conveniently embodying my invention. 1. i

Fig. II, is a sectional elevation of the same as viewed in the direction of arrows II-II in Fig. I..

Figs. III, IV, andV, are detail views on an enlarged scaleof. the tilting devices for the feed belts. v l

Fig. IV, is a detail view'of one of the runways illustrating the method of guidance forv the confections and also the ejection of an improperly placed confection. Figs. VII, VIII, and IX, are cross secthis application filed August 9,

t'ions of the same taken respectively on lines VII VII, VIII-VIII, and .IXIX-, ,of Fig. VI. i I

The confections to be wrapped 1 are promiscuously discharged upon an: endless carrier 1, from a suitable hopper or other equivalent 1 1 container (not shown). This carrier ismountedupon, and driven by rollers, one of whichis indicated at 2, in Figs; I, and II- i v The carrier 1, clined chute 3. Along thischute and overhangingthe discharge end of the-carrier 1 are theguidestrips 4, spaced toform entrances to the runways and partitions-be tween them. Below the discharge end of the chute '3, is another. seriesof guiding walls 5, which. accomplish a narrowing of the runways, Corresponding to each of these runwaysisan endless carrier band 6,

discharges by way of an inmountedfat one] end upon a pulley-7, on the similar and,ad ustable tensionis put-upon all of the endless bands 6. I

Thesebands 6 pass between "the guiding walls 5, and then across an opening 11,

where theban'ds lack any side protection,

and-'are'sub'ected to tilting means." Extend ing'aoross t is opening immediately beneath the bands is a rockshaft 12, to the operative crank. 13, of which, is pivoted a linlr 15, capas ble ofbeing reciprocated in any well, known manner. Thisrock shaft 12, carries tilting collars 16, set one beneath each band 6. One of these is clearly shown in perspec tive in; Fig. V. It'is provided with two inclined surfaces1717, one sloping inone direction, and the other inthe opposite, and so related to each other-thatas the shaft 12 rocks, these inclined. surfaces/17,17 alternately push. against the'lower face-of each endlessband 6, and tiltit firstto one side and then to the other. The inclination of thesesurfaces 17-17, asshown in Fig. III, isinot sufficient to cause a confection resting upright to tumble off the band 6, but if a confection has reachedv said band rest ing upon its side, as shown in Fig. IV, the inclination or tilting of the band 6, due to the tilting collar 16 causes it to fall off, dro ping down to a receptacle 20, whence conihctions may be returned from time to time to the hopper. The interruptions in the runways also provide a means of eliminating an excess of confections, since suchv excess cannot remain on the bands 6 where there are no retaining sides to the runwa s. r

.or the remainder of its operative travel, each endless band 6 passes along'a metal channel 21. Initially, this channel 21 has low edges, as shown at 22-22, in Fig. VII, but first one edge is turned partway over, as illustrated in Fig. VI, at 23, and then the other, as shown at 24, so that during the latter part of its travel, the band 6 draws the confections through a partially closed channeled runway of such shape'that the confections are confined in their lateral movement, so that they cannot stagger enough to lock, and in their vertical movethe tilting collars 16 have for any reason failed to eject mis-shapen or improperly positioned confections, the turned edges 23, and 24, will insure this ejection after the manner illustrated in Figs. VI, and VIII.

In dropped goods, notwithstanding the variations in shape to which they are subject, there is a plane at a determinable height above the base at which all the goods have a common cross-section, and the channel 21 is so shaped that the line of contact of the channel sides touches the sides of the con-- fections in this plane.

As the confections pass along the runways, they are subject to inspection, while the rejection of any imperfect or misshaped I confections may be thusmanually facilitated if desired.

2 Channels 21, lead directly to a wrapping mechanism not shown, and by reason of the interposition of the devices above described, the confections are delivered positively in upright positions to the elements by which their envelopment is subsequently efi'ected.

-Having thus described my invention, I claim:

1. In a machine of the class described, a carrier band for conveying confections to a point where the are to be wrapped, means for placing con ections upon the band, and means whereb the carrier band is intermittently incline from the horizontal so that confections which have'reached said hand using upon their sides are caused to fall refrom.

2. In a machine of the class described, a carrier band for conveyingconfections to a point where the are to be wrapped, means for placing con ections upon the band, and tilting mechanism whereby the carrier band ment so that they cannot capsize. In case is intermittently inclined from the horizontal so that confections which have reached said band resting upon their sides are precipitated therefrom.

3. In a machine of the class described, a carrier band for conveying confections to a point where they are to be wrapped, means for placing confections upon the band, tilting mechanism whereby the carrier band is intermittently inclined from the horizontal so that confections which have reached said band resting upon their sides are precipitated therefrom, and a runway traversed by the carrier band having means for aligning the confections before they pass from'sai runway. Y

4. In a machine of the class described, a carrier hand for conveying confections to a point where the are to be wrapped, means for placingcon ections upon the band, tilting mechanism whereby the carrier band is intermittently inclined from the horizontal so that confections which have reached said band restingupon their sides. are precipitated therefrom, and a channel-section runway traversed by the carrier band having'its sides m'erginginto overhanging parallel relation, whereby an improperly positioned confection is ejected and the rest are moved into aligned relation centrally of the carrier band.

5. In a machine of the class described, a carrier band for conveying confections to a point where they are to be wrapped; means for placing confections upon the band; a rock shaft mounted below the band and provided with'inclined surfaces sloping in different directions, which, as the shaft rocks, intermittently incline the band first one way and then the other, whereby the confections which have reached the band restin upon their side are caused to drop off sai band.

6. In a machine of the class described, a I

runway for the confections formed by a channel, a part of which near the receiving end has low longitudinal edges, whereas for the remainder of itslength the sides overhang sutliciently to reject misplaced confections, in combination with a carrier band traveling along the runway; and means for 1=ontinuously feeding confections thereto, whereby the pressure of the on-coming line of confections traveling in the runway causes a misplaced confection which has been halted by the overhanging sides to be rejected and fall out of the channel.

'7. In a machine of the class described, a combination with a carrier band for conveying confections to a point where they are to be wrapped, of a channel section runway having longitudinal relatively low entry edges merging into overhanging parallel portions, said overhanging portions be- 8. In a machine of the class described, the combination with a carrier band for conveying confections to a point where they are to be wrapped, of a tilting mechanism comprising a rock-shafthaving a collar provided with peripheral and reversely inclined projections, and means for rocking said shaft whereby the carrier band is intermittently tilted to the right and left hand relative to its line of travel for the purpose 1 I specified.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania, this 7th dav of August, 1923.
