- the machine embodying the herein disclosed invention is intended to utilize any suitable sheet material, and particularly thin transparent material such as regenerated cellulose, preferably of the moisture proof type or any similar moisture proof transparent or semi-transparent material hereinafter referred to as packaging material, and in using such material, the sealing of the bottom, top, and if desired the side seam also, may be effected by the application of heated sealing units.
- the sealing members are preferably heated electrically by the use of resistance material. It will be understood, however, that the invention is not limited in this respect and it is contemplated that the joining of the material to form the tube top, bottom and side seams shall be by the use of adhesives or folds or any other improved method.
- I have shown generally a vertically disposed frame comprising the angle members I supported both for rigidity and to provide supports for other mechanism at spaced intervals by the angle members I21, I4, I6, I8, 20, 22 and 24.
- I provide pairs of supporting brackets 26, 28, 30 and 32 for a plurality of reels R of packaging material M.
- the packaging material may extend upwardly over the guide rollers 34 and around a directing roller 36 mounted in brackets 38 on the uprights 40 which form a part of the support for the hopper 42.
- the hopper 42 communicates with the revolving mechanism 44 provided with vertically disposed measuring cylinders 46.

- Figs. 3 to 6 the formation of the cylindrical tube will now be described.
- the feed tube 64 is provided with a semispherical cap 66 which causes the web of paper being drawn down about the same to take a natural formation thereabout and form the greater portion of a complete circle as it is drawn down around the tubular feed conduit 64.
- one of the edges M is overlapped over the other edge M so that as the material passes down around the conduit 64 inside of a guide collar 68, the material will be practically formed into a complete circular tube with the edge M overlapping the edge M In this position it is guided downwardly through a pair of similar collars I0 and I2, and when the web reaches the region of the side sealing means I4 the material is overlapped and may be sealed by a slight pressure of the heat sealing means against the side of the tube.
- the collar 68 may be adjustably mounted in a vertical bracket 69 which extends downwardly to support the same from the angle support members 22.
- the mechanism has all been devised as a duplex machine, consequently using two rolls of packaging material to provide a double thickness'package, and duplicate parts throughout the machine for making and filling the bags. Since these parts are identical, only one complete assembly will be herein described.
- the heat sealing means I4 for effecting the longitudinal seal in the tubes may comprise a heating member connected to a source of electricity by the conduits I6.
- Each of the heating members are mounted upon a bracket I8 supported upon vertical shafts positioned between the support members I6 and I8.
- a spring member 82 normally tends to hold the sealing member against the tube 64.
- To provide an intermittent motion I have provided a pair of rocker arm members 84 adapted to be rocked from the drive mechanism by the rod members 86. The arm 84 is thus rocked through a short angular motion with its end bearing against the bracket 18 so that in timed relation with the other mechanism the heaters I4 are moved away from the tube 64 during said intervals of operation.
- This mechanism may include dual sets of face gears mounted upon cross shafts 92 and 94 supported in brackets 96 and 98 upon the cross frame members I 2.
- the face gears which are of exactly the same size and engage each other, may be driven by a pair of bevelled gears I00 and I02 mounted upon a cross shaft I04.
- the shaft I04 is mounted in suitable bearings I06 and I08 connected to the vertical uprights I0.
- the drive for shaft I04 may be obtained from a suitable source of energy such as the electric motor IIO which carries a pulley 2 that drives a drive pulley II4 keyed to the shaft I04 by a plurality of belt members II6.
- Each of the four f-ace gears 90 carry a pivotally mounted connecting rod H8 which extends upwardly (see Figs. 7, 8 and 9), and connects to a pin I20 carried by a pair of levers I22 and I24.

- the rods I38 extend upwardly and are provided at their upper extremities with piston rod-s I40 that travel up and down in a cylinder I42 which is filled with oil or other suitable material.
- sealing jaws connected to the pistons I40 The purpose of having the sealing jaws connected to the pistons I40 is to provide the desired pressure upon the heat-sealing members during their downward stroke as well as to regulate the timing of the entire mechanism during its operation.
- .Ihe cylinders I42 as shown may be mounted upon a cross platform I46 positioned upon the support members I6, and may be connected at their upper ends by a cross brace I48.
- the making of the upper and lower seals of the bag is effected by a pair of sealing jaws I60 and I62 carried by the support bars I28.
- the sealing units may preferably be heat-sealing of the type used for making th longitudinal seal, and may be connected to a suitable source of electricity .to heat the same to the desired temperalture.
- the operation of the heat-sealing jaws is as follows: When the machine is started and the material has been formed about the filling tube 64 and reaches a point below the end 64a of the filling tube 64, the gears 90 will have revolved so that the connecting rods H8 will have carried the bearings I26 to their uppermost position.
- I provide a pair of knife members I80 which are mounted upon a cross bar I82 that is carried upon horizon tal stub members I84 of one oi the seal support bars I2 8.
- the knife support bars I-82 also carry a U-shaped member I86 which, during the upward travel of the jaw assemblies, is raised upon the outside of a pair of vertically disposed blades I88.
- the jaws are olosed u pon the beginning of the downwardslllloke tlre q frame I86 which connects to the crossl,member I82, is kept in the extended position during the downward travel of the jaws during thesealing operation.
- the U-rod I86 passes below the end of the blades I88, and by reason of the spring members I60 connected to the cross member I28,
- the knife assembly including the flat blades I80, the cross bar I82 and the U-rod I86, is pulled forward sharply, the knife traveling through the slot I92 in the frame I28 and th slot I94 in the heat-er element I60, thus sharply and quickly severing one bag from another at a point midway between the extremities of the seal.
- the upper and lower seal of adjacent bags is made simultaneously, and during the same cycle of operation and at the end ci a sealing operation, the lower bag is severed from the next higher bag.
- the severed bag may drop by gravity upon :a receiving platform 200 pivotally connected to a pair of movable bearings I 26, from which, during the reciprocation of these bearings, the bags are shaken off upon a suitable conveyor 202 to carry them from the machine.
- the filling mechanism is stopped, the longitudinal seal is moved away from the tube, the jaws grip the closed bag at a point above the top level of the charge of the product, move downwardly carrying the tubular bag with them, seal the upper end .of the filled bag and the lower end of the next succeeding bag, and at the bottom of their stroke the knife members snap into position and cut off the lower bag.

16 Claims.
My invention relates to machines of the general type capable of manufacturing or forming a bag, package or container from a roll of material, filling the same with a product in measured quantities and then closing the package and disconnecting it from the roll.
My invention relates more particularly to machines of this type that are automatic in operation and capable of making and filling bags in a continuous uninterrupted process.
Machines of the general type mentioned have been on the market for some time. Each of them, however, has certain defects in construction and operation which limits to some degree its usefulness and type of material which it can handle. For example, each of the machines of the prior art employ a forming device for forming the flat material from which the bag is constructed into a tubular shape. The packaging material is drawn from a reel and passed over the former by which it is bent to a tubular shape and the overlapping side edges are sealed to form the package. The bottom of this tubular portion is sealed; the article to be packed is dropped through the entire tube to its bottom; the top of the container is then sealed, preferably while it is still attached to the remainder of the tube; the filled container still attached is pulled down to the delivery position and severed from the remainder of the tube.
The bending of the package material over the former tends to tear and rip the same with the result that the machine must be stopped frequently to rethread the packa e material. While Cellophane or other similar bag material is extremely tough and does not tear so easily, other substances such as paper, glassine and other more frangible material tears and rips easily, particularly if flexed or bent over sharp corners or steep angles.
The principal object of my invention is to provide an improved package making and filling machine with a packaging material feed so arranged with respect to the filling tube that no forming mechanism need be employed, the packaging material being fed from above directly around the filling tube.
A further object is to provide a construction and assembly of elements, in a machine of the class described so constructed that tearing, ripping and otherwise disrupting the package material as it comes from the reel is eliminated.
A further object of the invention is to provide an improved longitudinal seal member for sealing the side edge of the tube and improved means for operating the same.
A further object is to provide improved crosssealing means for closing the upper and lower ends of the filled bags with automatically operated knife means that cut the filled bag from the lower end of the tubular column of package material.
A further object of my invention is to provide an improved combined heat-sealing and knife means whereby one bottom and one top bag seal is made and the bags are separated between said seals all in one cycle of operation.
A further object of my invention is to provide improved and simplified drive means for operating the mechanism described including means associated with the heat sealing members for intermittently advancing the package material from the rolls through the entire machine.
A further Object is to provide a sealing means for making the top and bottom seals in the bags capable during the sealing period of advancing the package material through the machine.
Other objects and advantages will be more apparent from the following description wherein reference is had to the accompanying six sheets of drawings, upon which Fig. 1 is a front elevational view of my improved machine;
Fig. 2 is a side elevational view thereof;
Fig. 3 is a somewhat diagrammatic View illustrating the manner in which the Web of package material passes over feed rollers to the top of the filling tube;
Fig. 4 is a fragmentary front elevational view of the parts generally shown in Fig. 3;
Fig. 5 is a fragmentary plan view of one of the horizontal feed rollers and the filling tube;
Fig. 6 is an enlarged sectional view through one of the guide collars for the web of material, and is taken on the line 66 of Fig. 3;
Fig. 7 is a fragmentary plan view through the lower part of the drive mechanism taken generally on the line 1-1 of Fig. 2;
Fig. 8 is a similar fragmentary section with parts of the frame omitted a short distance above Fig. '7; is taken generally on the line 8-8 of Fig. 2, and illustrates the bag sealing and severing mechanism in a closed position;
Fig. 9 is a fragmentary vertical sectional view through the machine taken generally on the line 9-9 of Fig. l and illustrates the bag closing mechanism in a position just starting to pull down on the web of material. The lowermost position of the closing jaws is shown in dotted lines in the same figure;
Fig. 10 is a fragmentary changed position view of the closing jaws of Fig. 9 shown just prior to the time that they have been closed about the bag and started on their downward stroke;
Fig. 11 is a similar fragmentary view showing the operation of the knife member in severing the packages;
Fig. 12 is a fragmentary plan view similar to Fig. 8 with the sealing jaws and associated mechanism shown in the same position as Fig. 10; and
Fig. 13 is a fragmentary vertical sectional view through the machine taken generally on the line l2I2 of Fig. 1.
The machine embodying the herein disclosed invention is intended to utilize any suitable sheet material, and particularly thin transparent material such as regenerated cellulose, preferably of the moisture proof type or any similar moisture proof transparent or semi-transparent material hereinafter referred to as packaging material, and in using such material, the sealing of the bottom, top, and if desired the side seam also, may be effected by the application of heated sealing units. Hence, in the construction shown, the sealing members are preferably heated electrically by the use of resistance material. It will be understood, however, that the invention is not limited in this respect and it is contemplated that the joining of the material to form the tube top, bottom and side seams shall be by the use of adhesives or folds or any other improved method. It is feasible in some instances to feed the articles into the tubular feed conduit either by hand or by hand controlled mechanism, but it is preferable in most cases to feed it automatically in timed relationship to the formation of the container. By so doing a very considerable speed of operation is obtained. Automatic feeds which may be employed will take different forms, depending upon the material to be fed and the quantity. In the form of the invention shown in the drawings, the feed mechanism is designated to feed into each container a measured quantity of small articles such as popcorn, peanuts, cracker jack, or other similar articles, and in the embodiment shown I have preferred to employ the type of feed mechanism shown and described in the patent to C. W. Vogt, No. 2,113,636; also, it is understood that other types of automatic feed mechanism may be employed.
In the embodiment of the invention which I have chosen for illustration, I have shown generally a vertically disposed frame comprising the angle members I supported both for rigidity and to provide supports for other mechanism at spaced intervals by the angle members I21, I4, I6, I8, 20, 22 and 24. I provide pairs of supporting brackets 26, 28, 30 and 32 for a plurality of reels R of packaging material M. The packaging material may extend upwardly over the guide rollers 34 and around a directing roller 36 mounted in brackets 38 on the uprights 40 which form a part of the support for the hopper 42. The hopper 42 communicates with the revolving mechanism 44 provided with vertically disposed measuring cylinders 46. These cylinders are rotated in timed relation to the sequence of operations of the machine by shaft members 48 drivingly connected to a pair of face gears 50. A pair of bevelled gears 52 connect the shaft 48 in driving relation to a ratchet 54 which is turned a portion of a revolution for each operation by a dog member 56 connected to a reciprocating lever 58.
The lever 58 is connected by a rigid rod member 60 to one of the brackets 62 hereinafter to be described.
Referring more particularly to Figs. 3 to 6, the formation of the cylindrical tube will now be described. When the web of material M passes over rollers 34 and 36, it is bent back upon itself and pulled around the vertical feed tube 64. The feed tube 64 is provided with a semispherical cap 66 which causes the web of paper being drawn down about the same to take a natural formation thereabout and form the greater portion of a complete circle as it is drawn down around the tubular feed conduit 64.
When the material is first threaded through the machine, one of the edges M is overlapped over the other edge M so that as the material passes down around the conduit 64 inside of a guide collar 68, the material will be practically formed into a complete circular tube with the edge M overlapping the edge M In this position it is guided downwardly through a pair of similar collars I0 and I2, and when the web reaches the region of the side sealing means I4 the material is overlapped and may be sealed by a slight pressure of the heat sealing means against the side of the tube. The collar 68 may be adjustably mounted in a vertical bracket 69 which extends downwardly to support the same from the angle support members 22.
As can be seen in Fig. 1, the mechanism has all been devised as a duplex machine, consequently using two rolls of packaging material to provide a double thickness'package, and duplicate parts throughout the machine for making and filling the bags. Since these parts are identical, only one complete assembly will be herein described.
The heat sealing means I4 for effecting the longitudinal seal in the tubes may comprise a heating member connected to a source of electricity by the conduits I6. Each of the heating members are mounted upon a bracket I8 supported upon vertical shafts positioned between the support members I6 and I8. A spring member 82 normally tends to hold the sealing member against the tube 64. To provide an intermittent motion I have provided a pair of rocker arm members 84 adapted to be rocked from the drive mechanism by the rod members 86. The arm 84 is thus rocked through a short angular motion with its end bearing against the bracket 18 so that in timed relation with the other mechanism the heaters I4 are moved away from the tube 64 during said intervals of operation.
The mechanism for making the cross seals and at the same time moving up and down to pull the web of material through the machine will now be described. This mechanism may include dual sets of face gears mounted upon cross shafts 92 and 94 supported in brackets 96 and 98 upon the cross frame members I 2. The face gears, which are of exactly the same size and engage each other, may be driven by a pair of bevelled gears I00 and I02 mounted upon a cross shaft I04. The shaft I04 is mounted in suitable bearings I06 and I08 connected to the vertical uprights I0. The drive for shaft I04 may be obtained from a suitable source of energy such as the electric motor IIO which carries a pulley 2 that drives a drive pulley II4 keyed to the shaft I04 by a plurality of belt members II6.
Each of the four f-ace gears 90 carry a pivotally mounted connecting rod H8 which extends upwardly (see Figs. 7, 8 and 9), and connects to a pin I20 carried by a pair of levers I22 and I24. Each of the levers I22 is connected to a vertically disposed sliding bearing I26 and each of the levers I24 is connected to a cross seal bracket I28. The bearings I26 reciprocate upon vertical rods -I=2'I fastened between the cross frame members I4 and IS. The bearings I126 are joined on each side by an adjustable cross bar I 30 provided at its opposite ends with right and left hand threads, whereby the tension upon the seal members may be increased or decreased. The pin members I20 are joined upon each side by a compression spring member I 32 for assisting in drawing the same together during a certain portion of the operation. The bearings I26 upon opposit sides of the machine are connected by a cross brace I34 which carries 'a socket I 36 into which a vertically disposed rod -I38 is fastened. The rods I38 (see Fig. 13) extend upwardly and are provided at their upper extremities with piston rod-s I40 that travel up and down in a cylinder I42 which is filled with oil or other suitable material. the operation of the machine, on the upward stroke of the piston I40 the oil is forced out and below the piston by means of a small by-pass I44, and during the down strok of the piston the action is reversed and the oil or other fluid is forced upwardly in the same manner.
The purpose of having the sealing jaws connected to the pistons I40 is to provide the desired pressure upon the heat-sealing members during their downward stroke as well as to regulate the timing of the entire mechanism during its operation. .Ihe cylinders I42 as shown may be mounted upon a cross platform I46 positioned upon the support members I6, and may be connected at their upper ends by a cross brace I48.
The making of the upper and lower seals of the bag is effected by a pair of sealing jaws I60 and I62 carried by the support bars I28. The sealing units may preferably be heat-sealing of the type used for making th longitudinal seal, and may be connected to a suitable source of electricity .to heat the same to the desired temperalture. The operation of the heat-sealing jaws is as follows: When the machine is started and the material has been formed about the filling tube 64 and reaches a point below the end 64a of the filling tube 64, the gears 90 will have revolved so that the connecting rods H8 will have carried the bearings I26 to their uppermost position. Due to the sets of links I22 and I24, the jaws I60 and I62 will have been retracted to the position shown in Fig. on their upward journey, thus passing upwardly about the sides of the bag. As the rods .I I8 pass over the peak of their rise and start to descend, the links I22 and I2=4 will be moved apart by the initial downward pulling action and the jaws will be forced together upon opposite sides of the material of the formed tube. Due to the retard action of the cylinders I42, a large amount of pressure will be brought to bear through the sealing jaws against the opposite sides of the material. This pressure will remain throughout the downward stroke of the rods M6, during which the jaws are carried downwardly to the dotted line position shown in Fig. 9. At this point it is desirable to sever the connection between the top of a lower bag and the bottom of the next highest bag.
Accordingly (see Figs. 8 and 11), I provide a pair of knife members I80 which are mounted upon a cross bar I82 that is carried upon horizon tal stub members I84 of one oi the seal support bars I2 8. The knife support bars I-82 also carry a U-shaped member I86 which, during the upward travel of the jaw assemblies, is raised upon the outside of a pair of vertically disposed blades I88. As the jaws are olosed u pon the beginning of the downwardslllloke tlre q frame I86 which connects to the crossl,member I82, is kept in the extended position during the downward travel of the jaws during thesealing operation. When the sealing jaw assembly has reached the position shown in dotted lines in Fig. 9, the U-rod I86 passes below the end of the blades I88, and by reason of the spring members I60 connected to the cross member I28,
the knife assembly, including the flat blades I80, the cross bar I82 and the U-rod I86, is pulled forward sharply, the knife traveling through the slot I92 in the frame I28 and th slot I94 in the heat-er element I60, thus sharply and quickly severing one bag from another at a point midway between the extremities of the seal.
In this manner the upper and lower seal of adjacent bags is made simultaneously, and during the same cycle of operation and at the end ci a sealing operation, the lower bag is severed from the next higher bag. The severed bag may drop by gravity upon :a receiving platform 200 pivotally connected to a pair of movable bearings I 26, from which, during the reciprocation of these bearings, the bags are shaken off upon a suitable conveyor 202 to carry them from the machine.
The operation of rod 86 to move the longitudinal heater member I4 away from the tube 64 is accomplished .by a cam 206 mounted upon the shaft 92 and operating against a pivoted lever .208 connected to the lower end of rod 86. To assist in steadying the operation of the reciprocating jaws, I provide a pair of comparatively heavy spring members 2-I0 connected to the cross braces I60 at their lower end, and at their upper end to the frame member 20.
From the above and foregoing description it will be apparent that I have provided a comparatively simple and e-fdcient machine for making and filling bags. It can be seen that in the cycle of operation, the bag is form-ed about the filling tube through which the product is delivered, the longitudinal seal is made directly against the side of the filling tube, the sealing jaws move up and close the bottom oi the tubular bag, draw the same downwardly and effect th sealing simultaneously of the upper end of one bag and the lower end of another. During the return movement of the jaws from the lower to the upper position, the charge of the product with which the bag is to be filled is delivered into the bag. At the same time the longitudinal seal is being made upon the next portion of the tube. When the jaws arrive at their upper station, the filling mechanism is stopped, the longitudinal seal is moved away from the tube, the jaws grip the closed bag at a point above the top level of the charge of the product, move downwardly carrying the tubular bag with them, seal the upper end .of the filled bag and the lower end of the next succeeding bag, and at the bottom of their stroke the knife members snap into position and cut off the lower bag.
