15 Claims.

This invention relates to a packaging machine,

and particularly as may be applied to the canning of Vienna sausages or like mass of material wherein the sausages or the like are bunched, cut to packaging length, and introduced lengthwise into a can or similar packaging container.

It is the object of this invention to produce an automatic packaging machine having a series of aligned holders for the uncut bunched sausage or like mass of material, each holder conforming substantially in size and contour to the container to be filled.

As applied to the packaging of such material, said holders are mounted for intermittent travel *upon a series of individual endless conveyors, one

for each series of holders. At the loading station the holders extend in axial alignment to receive the material, which may be of several cans length to extend throughout the aligned holders and The end holders are then returned to the loading station whilethe intermediate holders continue to the next following packing station. Again the charges of material in the end holders are introduced into their respective aligned cans, their holders returning to the loading station while the intermediate holders progress to the next followin packing station until the last holder is unloaded and caused to return to the loading station.

, Onefeature of the invention resides in the car- .rier transmission for intermittently conveying the individual holders to their respective packaging stations and returning them to the loading station.

jAno'ther feature ofthe invention resides in the mechanism for introducing containers to be packed into axial alignment with the end holders as they reach their respective packing stations,

and discharging the containers after packing onto a" suitable conveyor.

Another feature of the invention resides in the packing plungers and means for actuating said plu'ngers in association with the aligned holders and containers at their respective packing stations for discharging thecharge of cut and 2 bunched material endwise from the holder into the aligned container in timed relation with the travel of the holders and containers to be packed therefrom.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

Fig. l-A is a side elevation showing the forward portion of the packaging machine carrying sausages to be packed.

Fig. 1-3 is a continuation of Fig. 1-A showing the rear portion thereof.

Fig. 2-A is a plan view showing the forward portion of the machine with the sausages removed.

Fig. 2-3 is a continuation of Fig. 2-A showing the rear portion thereof.

Fig. 3 is a section taken on the line 33 of Fig. l-A with the sausages removed.

Fig. 4 is a, section taken on the line 4-4 of Fig. l-A with the sausages removed.

Fig. 5 is a section taken on the line 5-5 of Fig. l-A with the sausages removed.

Fig. 6 is a plan view of the driving mechanism.

Fig. 7 is a sectional view of one of the charging plungers.

Fig. 8 is a sectional view of another one of the charging plungers.

In the drawings there is shown as one modification of the invention a supporting frame for the machine including the legs l0, a lower horizontal frame support II for the driving mechanism and an upper frame support l2 for the packaging mechanism.

Mounted on the upper support l2 for intermittent travel longitudinally of the frame there are a series of endless conveyor chains l3 of varying length, there being illustrated herein eight such chains. Said chains are carried and driven at the loading end of the machine by a series of sprocket wheels l4 mounted in axial alignment and each secured to a shaft I5 rotatably supported in suitable bearings provided by the upstanding bearing supports I6. Said shaft is driven by the sprocket wheel ll keyed or otherwise secured to one end thereof which in turn is intermittently driven by the sprocket chain l8 from the power plant which will be hereinafter described.

Each of the sprocket chains carries a series of holders I9 secured thereto at equally spaced intervals. Each holder is herein shown for purposes of illustration as cup shaped and open at the top to receive a charge of material which may comprise a bunch of sausages 5, being circular endwisethereof and of a transverse size or diameter substantially that of the container to be packed. The axial length of each holder is substantially the axial length of such container or can. At the loading end of the machine the holders are aligned axially as shown in Fig. 3, and spaced from each other sumciently to permit passage of a cutting knife therebetween.

The several conveyor chains [3 with their respective holders in alignment move in the direction of the arrow past the cutting station with respective holders passing between the rotary knives protected by the housing 2| extending over the upper periphery of said knives. As the holders approach and pass between the knives they travel under a series of aprons 21 having the effect of closing their open tops to prevent any displacement of the sausages. Said knives are arranged in a gang for rotation by the shaft 22 (Fig. 4), the shaft being supported by opposed bearing mountings 23 carried on the frame l2. In order that the holders l9 may be guided between the knives 26 they are each provided with dependinglugs 19 adjacent each end thereof. In alignment with each knife 2% there is an elongated guide rod or spacer 2i)? with which the adjacent lugs slidably engage. Secured to the end of the shaft 22- there is a sprocket E4 driven by the, chains 2i": as hereinafter described.

As the holders progress past the cutting station the knives 20 will cut. the bunched sausages to substantially the length of the holder and, therefore, approximately the. length of the can to be packed. The butt ends of the sausages will be discharged down the waste chute 215 Upon the holders, still in axial alignment, passing through the cutting station they progress to the first packing station. .At this station there is provided a can feeding rack 26 adjacent the outer side of each of the outer holders. Stacked in each rack there are a plurality of empty cans 2'! adapted to be fed by. gravity into axial alignment with the end holders into can recesses 34 within an arcuate can retaining cage 28. At the first such station, and within the retaining cage 28, the. outer conveyor chains [3 carrying the end holders pass about the idler sprockets 29.

The. intermediate conveyor chains with their holders continue on to the next packing station at which station the then outer chain conveyors and their respective holders pass about the idler sprocket zfl within the. cage 28 The remaining conveyors and holders pass onto the third packing station where again the outer conveyor chains with their holders pass about the idler sprocket 29 within the cage 28 The remaining intermediate conveyor chains with their holders continue on with one of them passing about the idler sprocket 299 in the cage 280, while the other passes about the idler sprocket 29 within the cage 28 Each of the idler sprockets 29 to 29 inclusive, are secured to the shafts 32--32 respectively, rotatably supported in adjustable bearings 3030 and to which shafts are secured the respective can receiving wheels 33v as shown in Fig. 5. Said bearings 3fi.-3B are respectively mounted on upright standards 3| to 3 I inclusive, and each can feeding rack is carried by a bracket 26 extending upwardly from the respective hearing standards.

Said wheels are provided with four equally spaced can receiving recesses 34 arranged to be brought into axial alignment with the holders l9 and moved therewith about the idler sprocket. As. the outer holders, l9 move about the idler sprockets degrees, they are separated from the intermediate holders, and extend in axial alignment with the empty cans within the can recesses 34. At this point the cans are ready for packing. The packing operation then consists in forcing the charge of sausages, severed to length, longitudinally and axially from the holder through a cone shaped guide 34 mounted on the wheel, and into its aligned can 21 as shown in Figs. 7 and 8.

Following the packing of the cans at their respective packing stations they are ejected from their recesses 34 by fixed ejector blades 3:? into the discharge chutes 35. This occurs as the filled recess progresses from its packing position toward its lowermost ejecting position. Each ejecting blade M is secured to the frame 12, extending upwardly therefrom an alignment with the transverse slots 34 extending about the wheel through and centrally of the respective recesses 34. The ejecting edge of each blade is curved in concentric spaced relation to the lower portion of the cage 28, being spaced therefrom substantially the diameter of a can. Thus the ejecting action is progressive from just past the pack ing position to its lowermost, position. From the chutes 35 the packed cans drop onto a suitable conveyor indicated at 36 which carries them from the machine.

For transferring the charge of sausages from one of the holders to the can, there is provided a lunger 3'! adapted to reciprocate axially of the aligned holder as and the can 2?. The plunger is actuated by a pneumatic piston and cylinder assembly 38, 33 to cause the plunger to eject the charge of sausages from the holder to the can during the dwell period in timed relation with its intermittent movement. Since the open end of the can directed inwardly toward the holder on the outer side thereof, the packing plungers are necessarily positioned intermediate the two outer holders to force the sausages outwardly therefrom at the first. three packing stations as in Fig. For thisv purpose, as shown in Fig. 7, the plunger Si is provided with a gooseneck or reversely directed piston rod connection 39. At the last two stations said plunger maybe connected with the piston and cylinder assembly 38 by a short straight piston rod connection 39 The power plant. for the machine, shown in Figs. l-A and 6, comprises a motor d0 which drives the belt and pulley transmission H to a variable speed transmission within the housing 2, the transmission driving the coupler shaft 43 leading to a speed reducing gearing within the housing M from which a Geneva rotator 15 is driven for intermittently rotating the Geneva wheel 45. A position retaining wheel 45 prevents backlash or movement of the wheel during the dwell period. The wheel of course drives the shaft 41 to which the sprocket wheel :13 is keyed. Said sprocket wheel drives the sprocket l'i through the chain !8. Air lines 50 and 58* connect an air control valve 5i with theseveral piston and cylinder assemblies 33 and 33 respectively. The air valve 5| actuated. and. controlled by a timing. cam 52 driven with the Geneva rotator shaft from the housing 44. A suitable source of compressed air is connected with the valve 5%. Thus, the air lines and the Geneva drive are synchronized. Through such timed relation, the plungers 3? are actuated to eject the, charge of sausage from the holder into he anduring the; pause the movem nt of the holder upon reaching its position of alignment between the can and the plunger.

The cutting knives 20 are driven by the motor 53 which, through suitable gearing indicated at 54, drives the sprocket 55 which drives the chain of aligned holders to be closely spaced for rapid loading and packaging.

Whereas the machine has been herein shown and described in connection with the canning of Vienna sausages, it is equally applicable to any other material to be packaged, the holders and the knives serving to form the individual charges from a bunch or mass of material to be packed or canned. Wherein the material is of such character that it may be distorted when the butts are trimmed off by the knives, the first series of outer or end holders may be utilized to support or clamp the end butts, discharging them as waste at the first station instead of packaging them. When this is practiced, the number of holders may be accordingly increased.
