PACKAGE-FILLING MACHINE.

Specification of Letters Patent.

Patented Apr. 10, 1917.

Application filed May 24, 1912. Serial No. 699,488.

To all whom it may concern:

Be it known that I, KARL GAMMEL, a subject of the Emperor of Germany, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvementsin Package- Filling Machines, of which the following is a specification.

My invention relates to package filling machines and has for its object the devising of means whereby packages may be filled with the required weight of the intended goods with a minimum amount of handling, on the part of the operator of the machines.

A further object of my invention is to provide a machine, continuous in its operation, wherein goods to be packed are weighed out in the desired amount and by a continuous process, are transferred to the package, which is then carried to a suitable place where it is removed from the machine and further disposed of as desired, as for instance, by transferring it to a moving platform where it may be carried to a convenient place for sealing or for otherwise handling it.

The various other objects of the invention will be more fully set forth in the following description of one form of mechanism embodying the invention which consists in the new and novel feature of construction and combination of parts hereinafter set forth and claimed.

Figure 1 is a central vertical section of the machine with some of the parts shown in full and showing the filling and emptying positions of the scales.

Fig. 9 is a plan with many of the parts removed, others shown in section, and others partly broken away showing principally the table and cams.

' Fig. 3 is an enlarged fragmental view of the left hand portion of Fig. 1 showing the parts in positions for removing the goods.

Fig. 4 is an enlarged fragmental view of the extreme right hand portion of Fig. 1 showing the parts in positions for weighing the goods.

Fig. 5 is a plan of a fragment of the machine comprised in the right hand portion of Fig. 1 and showing parts that were omitted in Fig. 2 in four different positions and,

Fig. 6 is a detailed central sectional view of the scale pan.

It will be apparent from the following description that the machine may be used for weighing and packing a large variety of goods. The machine is especially designed however, for weighing and packing such edibles as macaroni and similar products. Such goods are placed in the scale pans, comprised in the machine, in approximately correct quantities. For instance the goods may be measured by dry measure in approximately the desired amounts by any suitable means (not shown) and then placed in the scale pan. The scale readings indicate preferably, the number of pieces of macaroni or other goods required to be added or taken away to obtain the correct quantity.

The above illustrates one use the machine may be put to, but as before remarked its application is more or less general, and in most cases it is preferable that the scale be graduated to indicate weight instead of as above described, which latter graduations are only suitable where the goods packed are made up of substantially uniform pieces. Other than this the machine will require only such change, to adapt it for use with the various articles desired to be packed, as are within the scope of my invention.

The machine comprises a table 1 rotatably mounted upon a vertical shaft 2 through a hub 3 of suitable length and supported as through ball bearings 4; by the suitably constructed stand 5, into which is rigidly secured the shaft 2. The table is revolved by any convenient means, as the worm 6 and gear 7 A plurality of frames 8 are secured to the table as by clamps 9 and lock pins 10.

A scale is mounted upon each of these frames. A preferred type whereby the goods may be readily weighed and removed to the package, comprises a chute through which the goods are passed, an opening and closing end for the exit of'the goods, an op posite opening and closing end for the admission of the removing means, and means for covering the pan and for holding it rigid during the removing period.

The scales comprise a pair of balance beams 11-11 secured in spaced relation by bars 12 and bolts 13 to form a frame. This is fulcrumed to the frame 8 by means of knife bearings 14- supported by lugs 15. The two ends of the balance frame are pivotally connected to vertical frames; the outer frame being comprised of vertical bars 16 straddling the frame 8 and secured in spaced relation by fastenings at either end, and the inner frame being comprised of bars 17l. and other bars 18 18 secured in spaced relation by suitable fastenings at top, bottom, and intermediate positions thereof. he inner bars 17 extend upwardly and have secured thereon a support 19 for holding such weights (not shown) as may be found necessary to counterbalance the weight the goods being weighed. @ther weights are suitably mounted on pins projeeti g from the bars 17 to afford additional means for counterbalancing the goods weighed. The vertical frames are suspended from the ends of the balance frame by knife bearings 21 and 22 in the usual manner. They are weighted below their point of suspension, by weights 23, and maintained in vertical positions by links 24 pivotally connected to the ends of the frames and to the frame 8.

The scale pan 25 is rigidly secured to the upper ends of the bars 16, and for the particular purposes of the present construction is of a comparatively long trough shaped formation, and directed radially to facilitate the removal of the contents by the mechanism later to be described. During this period of transfer the scale pan is brought in contact with posts 26, upstanding from the frame 8 by means of pi e 27 secured on a. swinging arm 28 pivotally mounted on lugs 29 formed on the frames 8. The ends 30 of the scale pan are made removable through slots in the base thereof. They are supported .on arms 31 pivotally secured to the sides of the scale pan, and have branch arms 32 crossing in the path of the pins 27 to be struck by them in their downward movement to lower the ends 30, thereby leaving the pan free for the admission of the removing means the inner end and the removal of the goods at the outer end.

After the pins :27 have opened the ends of the pan they seat in the depressions formed in the sides of the pan and hole it firmly upon the posts 26. The arm is further provided with a plate 34- which enters the scale pan on its dowi vard move. ment, and serves as a cover therefor to facilitate the removal of the goods. The return of the ends 30 occurs automatically upon the raising of the arm 5'8 by means of springs 35 secured at one end to the respective arms 31 and anchored at their other ends to the scale pan.

A scale 36 is formed on an edge of the plate 34 which serves when in vertical position to indicate the amount of goods in the pan, although it is obvious that a permanent scale could be provided if desired. An indicator lever 37 is pivotally mounted on an arm 38 ri idly secured to the lug it One end of the lever is engaged by a pin 31' projecting from the adjacent ba 1? in its upward movement. The other end of the lever is arranged to pass over the scale 36 to indicate the weight of the goods in the scale pan, and is returnable to normal posi tion by the depended weight 40.

The arm 28 is reciprocated through its quarter revolution of motion from the vertical to the horizontal as shown by the broken are in Fig. 4, by means of a rod 411, pivo ally connected at its outer end within the bifurcated rear end of the arm and secured at its inner end to the slide bar loosel i, engaged in a groove formed in a drum 4:3

supported rotatably upon the shaft by collar 44-. The bar 42 is reciprecatec to the arm 28 by means of a cam 45 fixedly mounted on the shaft and engaging cam roller l6 rotatable on the bar 28 is positively lowered by this mechanism and is raised by a tension spring 4-7 secured at one end to the arm and at the other end to the drum, which also serves to retain the cam and roller in continuous engagement.

The drum i3 is rigidly secured to frames 8 by means of the tubular lial tier 48 whereby the drum revolved with the revolving table.

The goods are removed from the scale pan by means of a plunger secured to the outer end of the bar 50 which passes through the lug 29 and has secured to its inner end the head 51 adapted to reciprocate in the tubes 48. The plunger is reciprocated by means of an arm 52 pivoted at its lower end in brackets 53 secured to the base of the table, and having a slotted upper end for engaging roller 5-11: rotatably pinned in a slot formed in head 51. The arm 52 is posi tively moved outward to transfer the goods from the scale pan by means of cam fined on the shaft and a cam roller 5(3 secured on the arm. The plunger is returned to inactive position by means of tension spring 57 secured at one end to the r l 52 and the other end to hub 3 thro intervention of disk 58 secured thereto. ac spring at the same time serves to maintain the cam and roller in continuous engage- I ment.

The outer end of the scale pan is provided 59 over with a yielding chute or sleeve which the mouth of the paclra dotted lines at 60 is passed. is supported upon a swinging s pivotally secured to an extension on frame 8. The support is fern erably of the three sides 63,

62 f aed land or) which serve to hold the package while being filled pref- The arm and while being lowered. The rais"ig and lowering the support is accompli bed by means of a connecting rod pivotaliy connected to the support at one end and at the other end to arms 67 depending from slide bar 4(2 whereby the support is raised as the arm 28 is lowered and is lowered as the arm 28 is raised. The side 63 of the support 61 is provided with apertures (58 which registe'r with pins 69 extending from the front of the frames 10 as the support is lowered, whereby the filled package carried by the support is arrested and the support permitted to move free therefrom. The pack age then drops upon an endless belt 70 or other suitable conveyer, and is moved along where it can be sealed or otherwise handled as desired.

The cams l5 and 55 have their extended faces on the same side of the shaft in order that the operation of the different parts will be properly timed. The extended face 71 on the cam a5 is longer and begins in advance of the extended face 72 on the cam 55. This enables the scale pan to be closed at the top, the ends removed and the package supporter raised before t e goods removing plunger begins to operate.

Fig. 2 shows different positions of the cam rollers as they are traveling over their re spective cam surfaces. Fig. 5 shows four sections of the device in difierent positions of their travel over the extended surface 71. The lowermost section shows the parts as represented in Fig. 4 and the right hand Side of Fig. 1, while the uppermost section shows the parts in the position corresponding to Fig. 3 and the left hand side of Fig.1.

he above description has been confined to one section, but the other sections differ in nowise therefrom. Twenty-four of these sections are used in the present construction but the number may be varied as desired.

The operation of the machine is simple. The cams being stationary and the table continuously revolving, the parts will be as shown to the right in Fig. 1 for the greater part of the revolution. This gives the operator ampl opportunity to fill the scales with the required amount of goods and to slip the packages upon the sleeve or chute at the front of the scale pan. This must of course be completed before the cam rollers reach the extensions on the cam. Nhen this engagement begins the weighing has been completed and the particular section is in the neighborhood of the conveyor "elt. Here the package supporter comes under the package to support it, the top or cover to the scale pan comes down to cover it and to remove the ends of the pan. After this is done the plunger passes through the pan and forces the contents into the package. The cam wheels then continue on the other side of their cam extensions and the parts brought thereby to their first positions, the pan being then ready for a new charge. The lowering of the package supporter to its first position causes the projecting pins to hold the package in check and when the supporter has moved away, to permit the package to drop upon carried away for sealing and etc.

It can be seen from the above'that the machine is continuous in its operation and requires the minimum amount of handling of the goods intended to be packed.
