A suitable rin gear13 shown in the lower right hand corner o is secured to the member 8 as by olts'14 Figure 7. The ring gear 13 overhangs the.
bore in the member 8 and engages the upper marginal portion of the plate 9, whereby the latter will provide a -supportforthe ltable member 8, as will readily be understood by reference toFigure 4. A casting 15, having an upstanding annular flange 16, is suitably secured to the late 9 by such means as bolts 17, shown in Figure 7. An annular recess 18 is provided in the lower face of the casting adapted to receivethe ring gear 13, as shown in Figures 4 and 7. An inner cylindrical wall 19 is secured in fixedrelation to the flange 16 of the casting 15 and extends upwardly, as shown in Figure 4. An outer cylndrical wall 22 is secured to theI annulus 7 su .ported by the arms 6 of the bracket 5, an has its upper edge terminat# ing substantially inthe plane of the u er edge of the wall 19, asbest shown in igure 4.
Members 23 are secured to the circular table member 8 in spaced relation, as shown in Figure 1, and the adjacent side walls ofthe adjacent members 23 are arranged in substantiallyparallelrelation and cooperate with portions of the inner and outer cylindrical walls 19 and 22, to provide a series of spaced apart compartments, each adapted to receive filled bagn. u: i.
`The bottom ofeach compartment consists l VAof a movable plate 24, preferably having op- Vpositely extending ears 25 slidably engaged with guiderods 26 supported in the adjacent edge 'portions of -the vmembers 23, as best shown in igure 5. Suitable springs 27 are coiled about the guide rods 26 and have their lower ends engaged with the ears 25 of the plates 24, whereby a downward pressure is constantly exerted uponthe plates 24 to hold themin the position shown inl Figures 4V and 5. Resilient elements 28 such, for example, as rubber, are seated in depressions provided in the table member 8 and are adapted to support vthe plates 24 when in normal or lowermostpositions, as shown in ,Figure 4. Suit4 able clearance apertures 29 are provided in the sidewalls'of the members 23 to provide clearance for the ears 25 of the movable plates 24. Each movable bottom'24is provided with a depending rod 31, slidably received in hubs 32provided Aon the member 8, and each such rod 31 is preferably provided at its lower end l with a cap 33, as shown in Figure 4.
l Table 'vibrating meclzam'mf The means for imparting a vibratory or shaking motion to the table is here shown as consisting of a curved track 34 supported by a plurality of arms 35, preferably integrally formed with a circular frame 36 slidably supported upon the upright posts 11, as best shown in-'Figures 3 and 4. Pitman 37 have theirupper ends .pi'votally connected to the frame 36 as indicated at 38'inJFigure 4, and their lower ends operatively connected with cranks 39 suitably 'secured to a horizontal shaft 41 mounted in suitable bearings 42 provided inhangers 43 secured to the frame members 22 as'will ybe understood by reference to Figure 4. When the shaft 41 is rotated, an up-and-down motion will be imparted to the circularframe 36 which, Iin turn, will cause down into the bags. The leading end portion` 45 of the curved track 34'is shaped as shown in Figure 4,a'nd slopes downwardly sufficiently to cause the lower ends of the rods 33 to engagethe inclined upper face thereof, whereby the rods will ride upwardly over said face onto the horizontally disposed upper surface `of thetrack.
Table loading mechanism 'n a The means Afor successively feedin Ithe filled b ags into the compartments provi ed on the table is best shown in Figures 1 and 4, and comprises a loadin station Sincluding a small platformz46 W ereon the filled bags are placed as shown in Figure 1..- Thebags may be delivered to the station S from. a suitable bag filling and weighing machine, not shown in thedrawings.y g y. v l
vWhen paper bags are filled with iour or other finely divided material by an ordinary bag filling machine, the bodies-thereof usually become distorted so that they are more or less rounded in cross-section because .of the fact that such machines are not provided with means for retaining the bag-walls in properl shape during the fillingoperatijon. It is -a feature of this invention, in addition to the featuresof shaking andfeeding the bags,to shape the bodies .of the filled bags-so-that -whenthe latter are delivered toa bagclosing machlne, or other station, to havetheir tops closed and sealed, thewalls ofthe bag will be properly shaped whereby the bag when sealed, will presenta neat'appearance and all bags will be alike vinsizel and shape.
vThe means providedfor .thusjsha-ping. ther bagwalls is shown in Figuresli and 9, .and 'con sists of a pair ofy upright feed rollersf47.` and 48 operatively connectedtogether bya train* of gears 49 as shownin Figure 3, whereby the feed rollers` will rotate in opposite directions',` These rollers are located lat theloading station S. ,'Ilhe shortest distance between the perpheries of the two feed rollersis substantially less than the width o f-the bag 50,shown positioned upon the platform 46 at theload ing station S. .It therefore follows that when the bag 50 is fed by the rollers47` and 48 into the compartment alined therewith, the side walls of the bag will be pressed together so that the bag will readily enter' the'compartment, it being noted that the distance between the. peripheries of the rollersis also less than the widths of the pockets. -51 indicates a bag partially fed into a compartment of the feed rollers. 'When the bag 50 is fed between the rollers 47 and 48, rit will engagethe adjacent end of the bag 51 and move the latter into the compartment, until the leading end thereof engages and actuates a trip :lever`52` which' will cause the operating mechanism, which' will subsequently be described',to commence to function, and rotate the table one step, or -until the next following compartment moves into bag receiving position in alineme'nt with the two feed rollers. va The peripheral speed of the feed rollers .is substantially equalto the peripheral lspeed of the outer portions of the compartments so that as the bag 51, positioned in the comartment alined with the feed rollers, is fed rom the position shown in Figure 1 to the next succeeding osition indicated at B in Figure 1, the proJecting end wall of the bau will be pressed inwardly by the periphery of the'feed roller 47, as shown in Figure 9,l
whereupon the bag walls will be shaped to conform to the walls of the compartments,.
defined bythe spaced parallel walls of the members 23 and the inner and outer c lindrical walls 19' and 22, in which position the walls of the bags will be retained until the bags are successively ejected from the compartments. The means for thus shaping the walls of the bag forms an important part of this invention as it assures each bag as it is being vibrated to settle the contents therein,
is to be understood that the feed rollers areprovided with smooth peri heries so thatl they will not tear the walls o the bag which istemporarily held therebetween during rotation of the table from one step to the nextr i 'Feed roller operating means The mea for operating the feed rollers 47 and 48 shown in' Fi ures 2, 3, and 4, and comprises a bevel gear rive 53 adapted to be operated by a chain-and-sprocket drive 54, as shown in Figures 2 and The feed rollers 47 and 48 are provided with shafts 55 and .56, respectively, having intermediate poitiiis 'supported in suitable bearings 57 provided on the platform 46 of the loading station S. The lower portions of these shafts are rotatably mounted in bearings 58 supported upon the depending portion 59 of the platform 46. As here shown, the bevel gear drive 53 operatively connects the roller shaft 56 with the drive chain 54.
vThis chain is operated from a cross shaft 61 mounted in suitable bearings 62, preferably secured to the side frame members 2-2. The cross shaft 61 is driven from a main operating'shaft 63 by a suitable gear drive 64. The main drive shaft 63 may also function as a drive shaft for abag closing machine, not` shown in the drawings. The main drive shaft 63, the cross shaft 61, and the train of gears 49 are adapted for constant rotation.
Ak chain-and-sprocket drive 65 connects the crank shaft`41 with the cross shaft 61,
thereby causing the circular track 34 to operate continuously; when the feed rollers are rotating.
' Ejector `A'means for ejecting the bags from the compartments is shown in Figures 1 and 2, and ycomprises an upright"pusher plate 66 having a horizontally disposed portion 67 slidably Supported upon spaced apartrails 68 supported by uprightframe members 69 and ,71. L'The plate 66 is actuated by a con- 77v provided in the plate is suitably secured to the v table 81' is provided necting rod72 operatively connected with a crank arm 7 shaft 74 mounted in a suitablel bearing 75 provided in a bracket 76 and a lower bearing 9. The bracket 76 casting 15 by such meailis as bolts 78, shown in Figure 1.
T e the bags from the compartments and deliver them onto a suitable receiving means such, for example, as the receiving table 0I' conL veyer of a bag closing machine 79, a portion of which is diagrammatically illustrated in Figures 1, 2, and 3. As here shown, a fixed with upright side walls 82 and 83, between which fli hts 84 travel and feed the bags along the tale 81 to the bag top closing mechanism, not shownfin this application. The flights are operated by a conveyer chain 80. An operating shaft 85 is shown mounted directly7 a ove the main drive shaft 63 and has a suit.- able clutch gear wheel 86 loosely mounted thereon. The gear 86 meshes with a pinion 87 secured to the drive shaft 63, as indicated in Figure 2, whereby the gear 86 will rotate constantly with `the pinion 87. A suitable clutclrmechanism, not shown in the drawings, is provided within the gear wheel 86V and'is adapted to be actuated by an arm 88 to cause the Agear to become locked to the operating shaft 85, whereupon said shaft will rotate synchronously with the gear 86.` The,
shaft 85 is, of course, operatively connected with theconveyer chain so that when the shaft is rotated, the conveyer chain 80 will also operate. As' the receiving means bag closing machine) above described, forms no part of the present invention, it is 'unnecessary to describe the same in detail.'
, Zilaz'n operating mechanism The means provided for controlling the intermittent or step-by-step movement of the table is best shown in Figures 4, 6, and 7. A vertical shaft 88 is mounted in bearings 89 and 91 provided respectively in the bracket 5 and the plate 9. This'shaft has a bevel gear 92 secured to the lower end thereof which 'meshes with a pinion 93 secured to the hori? zontal shaft 41. The shaft 88 therefore operates continuously with the shaft 41, the latter being connected by the chain drive 65 to the cross shaft 61 which, in turn, is connected `r3 secured to thek upper end of a pusher plate 66 operates to discharge a series of conveyerv by the bevel shaft 63.
A pinion 94 is secured to the upper end of the shaft 88 and meshes with a gear wheel 95 loosely mounted upon a shaft 96 mounted in suitable bearings providedl in the bracket 76 and the plate 9, as shown in Figure 7. A crank arm 97 is keyed'to the shaft 96 directly above the hub of the gear 95 and carries a dog 98 adapted to be moved into engagement with an internal ratchet 99 provided in the gear 95. A suitable spring 101 connects the dog 98 with the crank arm 97 and constantly tends to move the dog into driving engagement with the ratchet 99, as will be noted by reference to Figure 8. A detent 102 is providedv upon the dog 98 and is positioned to be engaged b an abutment lever 103 pivotally mounte shown in Figures 1 and 6. The trip lever 52 is also pivoted to the casting 15, as indicated at 105 in Figure 8, and has one end projecting through an aperture 106 provided in the cylindrical wall 19 in alinement with the two feed rollers 47 and 48, and so that the trip lever may be engaged by a bag fed into the compartment alined with the feed rollers, as will be understood bylreference to Figure 1. The opposite end of the trip lever 52 is connected by a link 107 to the abutment lever 103, so that when a bag engages the opposite end portion of the trip lever, the arm 103 will be moved lout of engagement with the detent 102, whereupon the spring 101 will move the dog 98 into engagement with the ratchet 99 and causev the crank arm 97 to rotate synchronously with the gear 95. A suitable ten sion spring 108 normally retains the trip lever in the full line position shown in Figure 8. The trip lever 52 is shown provided with a hand grip 100 whereby it may be manually operated, when desired.
gears 64 to the main drive shaft 96 and is operatively connected with an intermittent pinion 111 secured to a sleeve 112 rotatably mounted upon a stud 113 secured tothe plate 9 andl bracket 76, as shown in Figure 7. The sleeve 112 is provided at its lower end with a spur pinion 114 which meshes with the ring gear 13 secured to the table member 8, as hereinbefore stat-ed. The4 intermittent gear 109 and pinion 111 are so designed and constructed that when the shaft 96 makes one revolution, the intermittent gear 111 will make one-third of a revolution,
whereby the table member 8 will be rotated one step, in this instance, one-eleventh of a revolution, whereupon the detent 102 of the dog 98 will engage the abutment arm 103 and cause the dog 98 to be moved out of engagementv with the ratchet 99 and thus tem` porarily interrupt further rotation of the shaft 96.
The ejector is actuated by an intermittent gear 115 secured to the shaft 96 and meshing upon the casting 15, as best with an intermittent pinion 116 secured to the' shaft 74 upon the upper end of which the crank arm 73 of the ejector is mounted. The
intermittent gears 115 and 116 are so designed that for each revolution of the shaft 96, the ejector crank arm 73 will make one revolution. These .gears 115 and 116 oper:-
.ate in timed relation with respect to the intermittent gears 109 and 111 so that the ejector does not commence to function until the table has been moved one full step, whereby a filled bag will be positioned in the path of the ejector, as shown in Figure 2.
When the novel bag shaker and feeder featured in this invention is operatvely connected with a bag closing machine, the operation of the latter is preferably controlled by the operation of the bag shaker and feeder. This may be accomplished by connecting the arm 88 of the clutch gear 86 with the operating mechanism ofthe bag shaker in such a manner that when the ejector is operating to eject a filled bag from a compartment and deliver it onto the table 81, the conveyer chain 8O of the bag closing machine will be at rest. As soon as the pusher plate has moved out of the path of the conveyer flights 84, on its back stroke, the lever 88 is operated to start the bag closing machine whereupon the conveyer chain 8O will operate to cause a flight 84 to engage the bag and feed it along the table or conveyer 81.
To thus actuate the lever 88, a suitable cam 117 is secured to the shaft 96 for direct rotation therewith. This cam is adapted to engage a roller 118 provided upon an arm 119 pivotally supported upon a bracket 121 suitablysecured to one of the upright guides or posts 11, as shown in Figure 3. The arm 119 Ais connected to one end of a rod 122, the opposite end of which is connected with the lever 88 so that when the cam 117 actuates the arm 119, the rod 122 will operate the lever 88 and cause the clutch gear 86 to operatively engage the shaft 85, whereupon the conveyer chain 80, which it is understood, 1s operatively connected with the shaft 85, will be operated one step, it being understood that the clutch gear 86 comes revolution in a manner similar to the gear 95, shown in Figure 8.
Operation fed into the compartment alined with the loading station. The bag, however, will come to rest in the position indicated at 51 in Figure 1. The next following bag 50 fed between the feed rollers, will engage the preceding bag 51 and move it into the compartto rest after each ment until the leading wall of thelatter engages the trip lever 52, whereupon the'mecha-k nism .will be actuated to cause the table to move one ste Because of the eripheral speed of the eed rollers being su stantially the same as the peripherall speed of the spacing members 23, the portion of the bag which projects out of the pocket into the gap be-V tween the two feed rollers will be pressed inwardly until the opposite end of the bag engages the cylindrical wall 19, as hereinbefore stated. It will also be noted, by reference to Figure 1, that the periphery of the feed roller 47 projects within the inner surface of the outer cylindrical wall 32, so that as the' 'bag leaves the feed roller 47, it will be confined within the opposite walls of the members 23 and the cylindrical walls 1.9 and 22,
which thereafter will retain the bag walls in proper shape. During rotation of the table, the bag positioned between the feed rollers will engage the outer surface 60 of the folf lowing member 23, as shown in Figure 9, which, having a smooth periphery, will slide ast the bag, at thersame time holding the ag against movement until the next followripheries of the feedrollers are` smooth sov that when the movement of the bag is tembag until the member 23 has moved out of engagement with the end of the bag.
The circular track 45 is of such length that f porarily interrupted by reason of one of the the rods 31 of the movable plates or bottoms i 24 of the compartments will move out of engagement therewith just lbefore each compartment comes to rest in alinement with the receiving means, in this instance, the table 81. The compartments, in traveling from the position in front of the ejector to the loading station S will remain idle, as willvreadily be understood by reference to Figure 3. The distance traveled by each bag from the time it is delivered into a compartment until it is ejected therefrom, 'is suicient to cause the vibratory action imparted to the plates 24 to cause the flour or finely divided material. contained in the bags to become thoroughly settled in the bags before the latter are ejected from the compartments. 4 The machine is also so constructed that it may vreadily be operated by an inexperienced operator, it being onlyvnecessary to place the bags on the platform 46 at the loading station S, whereupon the rollers 47 and 48 will successively feed the bags into the compartments and cause the machine to operate'.
