9 Claims.
1 My invention relates to improvements in machines for filling cases or the like and more particularly concerns improvements in case-fillingl machines including a discharge chamber or section which is gravity fed from a communicating magazine section.
In machines of this type, the flow of units to be packed, canned goods, for example, is arrested during each discharge operation by a gate between the two sections. When the gate is raised to permit the entry of additional units into the discharge section, there is an appreciable time lag before the units overcome their inertia and begin to gravitate toward the discharge section. My invention does away with this time lag, thus materially increasing the efliciency of the machine. In accordance therewith, I operatively associate with the means controlling the gate mechanism, means which, on restablishment of the conditions permitting ow of the units, positively initiate movement of the units.
I shall describe my invention with the aid of the accompanying drawings in which certain parts not directly related to the invention are illustrated diagrammatically and in which,
Fig. 1 is a side elevation of the working end of a case packing machine equipped according to the invention, and
Figs. 2 and 3 are sections on the lines indicated in Fig. 1.
In the drawings, the magazine section and the discharge section of the machine are indicated by the numerals IU and il, respectively. Within the magazine section and supported by the frame member I2 are superposed inclined runways or tracks I4 each of which has associated therewith ra pair lof outside rail members l5 and a spacer rail I6 (see Fig. 3). At either side of the runways is an assembly comprising a rotatable shaft I1 journaled in bearing plates IB and I9 secured to an upper false runway 20 and the lowermost run- Way, respectively. Keyed or otherwise fixedly secured to the shafts l1 centrally thereof are lever arms 2l carrying spring-loaded fingers 22 pivotally connected to the arms. The springs 23 urge the fingers inwardly about their pivot points (see Fig. 2). Lever arms 2l are connected to control bars 24 which, with their associated parts, will be hereinafter described, through connecting linkages 25 and 26. nected to the control bars.
In addition to lever arms 2l, each shaft Il has xed thereto `an upper and lower lever arm 21 and 28, respectively, carrying i'lngers 41 and 48, re-r spectively. These arms, unlike arm 2l, terminate Rods 25 are pivotally coni 2 at the shaft and are not directly linked to the control bar.
Within the discharge section il are a plurality of superposed trays 29 hingedly connected at their left hand corners to brackets 3D which may be fixed to the frame l2. Members 3l are adjustable stops. Mediate each pair of trays is a ram 32 (see Fig. 2) movable in the direction indicated by the arrow, the rams serving to clear the trays on the discharge operation.
Turning now to the control apparatus including the vertical bars 24, it will be observed that these bars are actuated through bell cranks 33 and 34 which are pivoted on pintles secured to brackets fixed to the frame I2. The lower arms of the bell cranks at each side of the machine are connected by Vertical bars 35 which themselves are linked at their lower ends through a shaft 3a extending under the machine. A lever system, terminating in a foot pedal 31 and including a balance lever engaged by limiting stops 38, connects with the shaft 36 through a linkage 48.
Extending between the upper and lower sections of the frame l2 are stationary bars 40 pivotally supporting bell-type crank members each comprising arms 4| and 42 and a journal pin 43 extending through the bar. Arms 42 carry rollers 44 .received by grooves 45 in the control bars 24, While arms 4l are connected to the trays 29 through short linkages 46.
In the operation of the machine, a constant backlog of the units being packed, shown as cans 5U, is maintained behind the magazine section which is thus replenished substantially as fast as it is emptied. In the case of the particular machine.. the cans enter the magazine section and pass therefrom into the discharge section in double les, the files being spaced by the rail members I6. v 'Y Assuming the several parts are positioned as in Fig. 1, the. operator releases ythe foot pedal 31, with the result that the bars 24 are shifted to the left by the action of the springs 39 which are under tension when the foot pedal is down. Shifting of the bars 24 isaccompanied by lower-l ing of the trays 29 to the positions indicated in dotted lines in Fig. l. In this position, the three uppermosttrays act as stops, preventing entry of additional cans into the discharge section. At
3 this point, multiple rams 32 are actuated to sweep the cans oi the trays into a case held by the operator.
When bars 25 are shifted to the left they carry with them the linkages 25 and 26, causing clockwise rotation of the shafts Il as seen in Fig. 2,
the arms 2lA being fixedly secured to the shafts. Thus all of the iingers held by the arms 2l, 27, and 28 are dragged vratchet-like over the chimes or rims of the adjacent cans, their ultimate positions being shown by the dotted line representation of iingers 22 in Fig. 2. It should be noted from Fig. 1 that the ngersvary in length depending upon the arms .onV which theyv are mounted.
The operator next depresses the foot pedal to bring the trays 29 into registry with the runways M. The consequent movement of the bars 2o to the right swings the finger-bearing arms inwardly so that the tips ofthe iingers engage with the chimes of the cans next following the rearmost cans acceptable on the trays. Accordingly, a positive initial thrust is given the cansmivhich compensates for. their inertia, and the discharge sectionv is more rapidly refilled with resultant obvious advantagesin respect of the time required to case. a given lot of cans. Engagement of the iingers with vthe chimes of the particular cans indicated is, of course, in no way critical, since a system iny which the ngers engage the rearmost cans acceptable by the trays, or cans two or three cansremoved from the rearmost cans, for example, is perfectly operable.
It is understood that the invention will not be considered as restricted to the precise details` of `construction indicated in the drawings, since various changes and modications may obviously be made without departing from the scope of theV invention or sacrificing the advantages derived romits use.
