'7 Claims.

Our present invention relates to certain new and useful improvements in packaging machines and it is the object of this invention to greatly simplify certain organization of` parts in machines of this type, to obtain higher efficiency in both production and costs; and further to produce such a machine having automatic actions to perform all of its principal functions.

A further object of theinvention resides in means for imparting an intermittent drag feeding action of the material which is to form the packages and also the material comprising the contents of said' packages, said feeding action occurring simultaneously with the hermetically sealing operation, and with the cutting operation for progressively severing the finished packages from a composite web train of connected portions divided by adhesive lines, each portion constituting a package when sealed and cut free ,from said web train. i

A further object being to provide cutting means for simultaneously trimming the side edges of package forming webs, said cutting means also functioning as guides for maintaining the web train in true alignment in its passage or movement through the machine.

A still further object being to provide means for printing a trade name or other matter upon the upper web or cover sheet of the web train immediately following the disposition of the contents cf a package upon the base web and before the introduction of said upper web upon said contents as a cover therefor.

A still further object being to provide means for applying marginal lines of adhesive to the base-web and means for applying predeterminately spaced transverse lines thereto and controlled by devices operated by the intermittently drag-feed mechanism.

A further object of the invention being to provide means automatically operable when the drag feed mechanism is moving in the feeding direction for progressively cutting the finished packages from the web train.

We will now enter into a detailed description of the construction as disclosed in the drawings in which similar reference characters are ernployed to designate corresponding parts throughout the several views, -it being understood that variations and modications may be made within the scope of the broader claims herewith submitted.

The improved packaging machine may include a suitable supporting frame I0, comprising top side bars Il, corner legs or posts I2, and lower' rods or laterally side bars I3, together with cross bars, `shafts if required to brace the frame forming the webbut in practice, the many operative cross shafts of the mechanism may act to tie the side frames or bars together.

At the rear end of the machine is a paste box I4, preferably mounted for forward and backward adjustment on supports I5 at each side of the machine (but one being shown) and on the opposite bottom corners of the paste box I4, are appropriate lugs or projections I6, which rest each in a pocket I1 formed in opposite rack bars I8, which are slidable on the supports I5, and are operated by a cross-shaft I9, having gear parts 20 to mesh with the rack bars I8, and said shaft is manually turned through a hand-wheel 2|, fast thereto, for the purpose of adjustably sliding the paste-box I4, forwardly or backwardly on the frame I5, to change the tension or length of the horizontal pasted port-ion 22, of a comparatively heavy web or back-sheet 23, taken from a convenient source of supply 24, and drawn around an idler roller upwardly and over a. platen-roller 26, then forwardly to printing, sealing and feeding devices hereafter described.

Longitudinal, and spaced cross lines of

paste

21 and 28, respectively, are applied to the backsheet web 22 as it traverses the platen roll 26, in the following manner and by devices which will now be described:

A feed-roller 29, dips into the paste 30 in paste-box I4 and is mounted on a cross-shaft 3l, having fixed on an extended end thereof, a pair of gears 32, and loosely mounted to rotate freely on this extended end is a third gear 33,

`carrying a spring-pressed dog 34, in contact with the teeth of the outer 0f said xed gears.

Constantly in mesh with the free running gear 33, is a reciprocating rack 35, hereinafter referred to.

The platen-roller 26, is driven through its shaft 36 and a gear 31, thereon by a central gear 38 of a train including the inner one of the double gears 32; thus the longitudinal paste lines 21, are applied to the upper face of the backsheet or web 23, by disk paste applying rollers 39 which are supported on a shaft 40, carrying the saidcentral gear 38, said disk rollers having constant operative contact with the paste feed roll 29 and the said back-sheet 23, as it is draw-n over the platen-roller 26.

In operation, the rack 35 when moving backward or to the right in Fig. 13, rotates the loosegear 33 and drags the dog or pawl 34 inoperatively over teeth of the outer one of the double gears 32, but when the said rack starts forwardly the dog 34 picks up the double-gears 32, and through the said gear train, including the inner of the double-gears 32, central gear 38, and platen-roller gear 31, the

rollers

29, 39 and 26 are turned to permita determined length 0f the back-sheet 23 to be drawn around and over the platen-roll 26, the lengthof the shift being the longitudinal dimension of a determined package to be formed. by the machine.

Attached to suitable brackets 4I, secured to the back of the paste-box I4 is a scraper-blade 42, extending longitudinally of the feed-roll 29 and in constant contact therewith,` for arresting excessive paste carried upwardly on said roll which paste excess flows back into said pan I4.

Referring yet to Figs. 1, 12 and 13 of the drawings, a rock-shaft 43, is journalled in bearings 44, extending upwardly from the rear corners of the paste-box I4, front bearings 45 on this box serving 'as journals for the platen-roller 26, as will be obvious.

The rock-shaft 43, has a gear 46 keyed thereto, with which a gear-rack 41, secured t'o a crosshead 48, is meshed, and these parts are operatively held in mesh by a suitable two-part box casting 49, having opposite tubular bosses 50 loosely encompassing the said rock-shaft for permitting the gear-rack 41 and the attached crosshead 48 to have oscillating movements for the purpose presently set forth; the two-part box casting being held together by a cross-bolt or screw 5I, see Fig. 12.

Fixedly supported above the ends of the pastebox, I4, are angle plates 52, each having an arcuate slot 53, through which, pins 54 extending from the ends of the cross-head 48 operate to guide and limit the movements ofthe said crosshead, when it is manipulated in the operation of the rock-shaft 43 through said gear-rack 41.

The rock-shaft 43 (Fig. 13) is extended at one side as at 55, and keyed to the shaft extension Just outward of the corresponding bearing 44, is a friction gear or disk 56 provided with a frictional facing 51 adapted for coaction with a second friction gear or disk 58, united by a hub 59 with a spur gear 60 resting on and in constant mesh with the main power gear rack 35.

'I'he unit constituted by the said second frictionygear 58, the spur gear 60 and the connect- 30 ing hub 59, is free on the shaft extension 55, and to maintain the said friction gears and facing in proper operative contact for driving shaft 43, a charged spiral spring 6I is interposed between the spur gear 60 and a collar 62, pinned to said 35 shaft extension 55.

The transverse paste lines 28, are applied to the back-Web 23 in the following manner: A paste pad 63', (Fig. 12), is carried by the cross-head 48, and in the back or the dead stroke rack 35, when the back-web is at rest, the

gears

60, 58, 56 and 46 on shaft 43, and the gear rack 41, cooperate to move the cross-head forward to cause the projecting pins 54 to abut the forward ends of the arcuate slots 53, in the angleplates 52, and assume the positions indicated in dotted lines in said Fig. 12, with the paste-pad 63, resting on said back-sheet over the platen roller 26, and when the power-rack 35 is reversed in a manner hereafter described, the motion of the above describedcooperating gears and gearrack will be reversed for drawing the cross-head 48 backwardly, causing 'the pinsA 54 to abut the rear ends of said arcuate slots 53 and support the cross-head and paste pad slightly above and over the axis of the feed roller 29.

The arcuate slots have upturned rear ends as at 64, to suspend the head in a manner to cause the pad 63 to clear' the feed roller 29; but at the beginning of its forward movement, to apply l.

a transverse paste line on the back-web, said cross-head takes a sharp drop to permit contact of the paste pad 63 with the feed roller 29, to pick up a fresh supply of paste therefrom.

The supporting frame I5 of `the paste box and v".

its associated parts, may be of any desired construction to permit of horizontal adjustment, through the operation of the gear or gears 20 and gear rack or racks I8.

Our primary power means may comprise an of the gear 40 Ul l aoamse of the printing block |88, by a set of inking as at 1|, to maintain accurate respective power drive for opposite cranks 13, each having cooperative adjustable means for assuring synchronous movement of their connected driven elements, including directly connected c rank rods 14,. in turn connected to rock-arms 15, through a. crossbar 16, connecting both of said rock-arms, at opposite sides of the machine.

Each of the cranks 13, Fig. 8, is of box-like form, having an integral tubular boss 15', into which the ends of the crank-shaft 12 project and are locked by a bolt or screw 11. The crankshaft has a central bore 18, extending entirely through from end to end, to receive a coupling shaft 19, having bevel gears 88, fast on its opposite ends.

The cranks 13' have each a longitudinal chamber 8|, closed at its ends by bolt-secured

caps

82 and 83, the former having a socket 84, in which one end of .an adjusting screw 85 may rotate, the opposite end of the adjusting screw passes through a bore 86 in the bolted cap 83 and is squared at 81 to receive a socket-wrench or the like for turning the screw for adjusting a threaded crank-pin block 88, having a crank-pin 89 extending outwardly therefrom, and passing through the eye 98 of a crank rod 14, which is held on said crank pin 89 by a cross pin 9 .v This adjusting operation is transmitted to a similar screw of a similar crank on the opposite side of the machine, through a bevel gear 92, in mesh with one of said bevel gears 88 and through said coupling shaft 19 rotatable in crank-shaft 12; said coupling shaft having keyed thereto another of said bevel gears 88 to mesh with another of the bevel gears 92 (not shown) on the opposite side of the machine.

The adjusting screw 85 may have a thrust shoulder 93, and the outside walls of the cranks 13, may be formed with slots 94 in which the crank pin blocks 88 operate.

The printing mechanism, preferably located about centrally of the packaging machine, will now be described in detail with reference to Figs. l, 2, 3 and 4 of the drawings:-

Secured to the top of the frame I8, through flanges 95 by bolts 95, is an upright frame 91, comprising vparallel .side members 98, securely4 braced by a top bar 99, secured to the top portions of rounded guide posts |88, which are secured to and rest on the top face of the side bars I I of the frame I8. Slidable on these posts |88, are sleeves |8|, connected by a cross-bar |82 formed centrally of its length with an up.

standing bracket |83, having a slot |84 for adjustably supporting, through a pivoting bolt, 9, a revoluble inkplate |85 having peripheral ratchet teeth |88, which in operation are progressively contacted, by a spring finger or dog |81, for turning said ink-plate in step movements, when said cross-bar |82 is operatively reciprocated as and for the reasons presently described.

Fixed on thecros-bar |82, at the base of the upstanding bracket |83, is a printing block |88, for-carrying printing type or characters |89, of any desired pattern, see Fig. 3.

The contents of the packages are designated at ||8, and the finished packages are shown at said contents maypreferably comprise a stack of lace paper doilies smaller than the paper pocket encloring them, but the. contents and packages may be of other material and design if desired.

Printing ink carried on the ink plate |85 may be transferred at intervals to the type |89 rollers II2, mounted on a swingable frame II3, suspended from a cross-rod ||4; the frame being urged forwardly` by a looped spring ||5, like, see Figs. 1, 2 and 4.

For supplying the upper or cover sheet, preferably of glassine, a transparent material, and to vimpose said cover sheet upon the contents of packages to be formed, the following means are employedz- Backwardly directed bracket arms I6, extendor the ing from each side member 98 of the uprightv frame 91, are formed with bearing slots ||1, to receive the journals of a cross shaft I I8, on which a supply roll I9, of glassine or other cover sheet material is leddown under a direction roll |28, thence over a platen roll I2 I, bodily swingable on a tiltable frame |22; thence over a tension roller |23, rotatable on adjustable arms |24; thence under a roller |25, supporting cutters |26 andthen forwardly over the progressive contents of packages tobe made, said contents resting on the lower web or base-sheet 23, in spaced relation.

The printing means, including the cross-bar |82, parts thereof and the elements supported' thereby, have operative lvertical reciprocatory movements on said guide posts |88 and to impart these movements in a positive manner, the upper ends of gear racks |21, are bolted as at |28 to the sleeves |8| of the cross bar |82, said racks passing through suitable guides |29, on the side rails II, of the frame I8, and are held in constant mesh with gears |38 and |3I, (Fig. 3) locked on a cross-shaft |32, operating in bearings |33 also fixed on`the frame I8; the gear |38 having an operative face wider thanv gear |3I, to overlap the reciprocating rack-bar 35 and mesh with it to take driving power therefrom, thu; the printing sequences are perfectly timed with the feeding movements `of the machine.

A rock-shaft |34, is mounted in the side mem- 'bers 98 of the upright frame 91, near its base and said rockshaft is pinned to hubs |35 of said arms of the tiltable frame |22, one of the side arms having an extension or arm |38, which carries a roller |31 at its free end, which runs on a circumferential shoulder |38, on the master gear 18; the shoulder being provided at a point along its face with a short cam |39, which coni.

tacts with and elevates the roller |31 at the proper time, for tilting the frame |22, to move the glassine `sheet traversing the platen-roller |2| into the path of the printing block |88 to receive an imprint therefrom, the said blockiD moving' downwardly with the identical speed of said glassine sheet, to avoid smearing the printed result, the above tilting operation beingshown in Fig. 4, showing the roller |31, riding over the cam |39, and the printing block |88, entering into contact with the glassine sheet ||9 moving downwardly over the platen roller |2| at equal speeds, as above set forth.

Bearing plates |48, are bolted to the opposite side rails of the frame and have upstanding for supporting a threaded cross, rod |42, on which the tension arms |24 are portions I4 I,

of a sprocket shaft |41, which has pinned thereto a power driven gear |48, meshing with the power t0 hold rack 35, and a sprocket |49, carrying a chain connection |50 to a smaller sprocket |5| loose on an end of said cutter shaft, said -sprocket |5|, being formed with `a side flange |52, which carries a pawl or dog |53, engaging in ratchet wheel |54, fast with said cutter shaft |25. This arrangement permits the cutters to be driven in the feeding direction only by the forward movement of the power rack-bar 35, the ratchet riding the ratchet teeth as the said rack is moving backward in its partially dead movement, the only part of the machine operatively activated in that movement are the rack-bars |21, which are raised for a new printing operation.

In vertical alignment with the cutter shaft |25, and free to rotate in proper bearings in the side rails or bars of the frame |0, is a crossshaft |55, having adjustable shearing disk cutters |56 thereon, for operative coaction with the other disk cutters |26, said disk cutters operating in relative overlapping relation for trimming the side edges of the package forming base and cover webs 23 and I9, respectively, and for conning said webs against lateral movement in their run to the sealing and feeding devices, as hereinbefore set forth.

We will now proceed to describe the mechanism for feeding the composite web train; for sealing the webs thereof to provide packages, for cutting said packages progressively from said web train and for delivering the individual packages to a point remote from the packaging machine:

Referring to Figs. l, 5 and 11 of the drawings, we supply a carriage |51, preferably constructed as best shown in Fig. ll, and mounted on the side bars of the frame I0, said carriage beingactuated by the power cranks 13, through the crank rods 14, to impart intermittent reciprocating movements thereto, said movements being regulated, through the adjustability of the cranks 13, to a-distance equal to that between the centers of the transverse pastelines between the particular packages being formed; the size of the packages as here shown being about eleven inches Square. Of course, the adjustability o'f the parts hereinafter described make it possible to form packages of various dimensions within certain limits.; the adjustability of the crank actions hereinbefore described being the main essential to the machines capacity of adjustment.

In Fig. l1 the carriage |51 is shown in enlarged partial cross section, and includes vslide plates |58, confined within spacing strips |50, both resting on the upper faces of the side bars of the frame, the outer portions of the slide plates f |58 and the spacing strips |59, being held in position by gib plates |60, secured by bolts |6|, extending through the spacing strips and into threaded sockets in the side rails as shown in said gure.

The slide plates |58 are each preferably formed with one or more sockets |62, to receive friction plugs |63, backed by charged springs |64, for constantly urging said plugs against the under faces of the gib plates |60, to create sufficient friction to retard the movement of the slidable parts of said carriages until a sealing plate 65,

is raised from sealing contact with the edges of the package in the making, as will appear herey inafter.

The oppositely directed fingers |13 arev arranged to oscillate under fixed hooks |14, fast to the sealing plate |65, to raise and lower said plate through the rock-arms 15, attached to the ends of the rear rock-shaft |10. The free ends of said rock-arms having bearings |16 for the cross shaft' v16, which shaft is connected at its ends to the upper ends |18, of the crank-rods 14, at the opposite sides of the carriage |51.

For maintaining the sealing plate in constant moving relation with the base table |68, upright pins |19, threaded into said table, pass loosely through holes |80, in said sealing plate, permitting the plate to rise and fall as power is applied to the rock-arms 15, as will be obvious.

Fixed to a side of the frame I0 of the machine, is an angle bar |8|, having a recess |82 therein. A gate-piece |83 is loosely suspended from the cross bar 16, and has a curved recess |84, which underlies a roller 85, riding on the edge of the angle bar, as the carriage |51 is vbeing forced forwardly in its sealing and web feeding move ment; near the end of this forward movement the roller |85, will drop into and quickly ride out of said recess |82, which action permits the downward movement of a cutter |86, hingedly`connected at |81, with the movablecarriage |51, said cutter carrying a fixed arm |88, supporting said roller |85, and a weighted arm |89 also carried on said cutter, assures a positive quick cut of the web material laterally between the finished packages.

When the power cranks 13 are forcing the carriage forwardly in the sealing and feeding movement, as in- Fig. 9, the thrust of the'crank-rods 14, through the rock-arms 15 and intermeshed gears |12, will force the oppositely movable fingers |13 into downward thrusting contact with the top of the sealing plate |65 to grip the edges of the packages with great force, thus assuring air-tight sealing of the webs.

Following the movement of the cranks past their feeding dead centers, and just prior to the pick-up movement of the carriage for its backward return movement, the rock-arms 15, are swung to the left in Fig. 10, dragging the wide end of the gate-piece |83, to the left and raising the roller |85, to the level of the top of the angle bar and thus raising the cutter to the inoperative position. In the backward swing of the rockarms 15, the companion shafts |10 and |1| are rocked in opposed directions through the interlocked gears |12 and the oscillatory ngers |13, now moving upwardly, will engage the shoulders of the hooks |14 and raise the sealing plate above the packages on the base table |68, prior to its backward movement with the carriage a distance determined by the throw of the power cranks 13, after which another cycle is begun with the release and drop of the sealing plate upon the next coming unsealed portion of the web train of packages to be made, and these cycles are repeated over and over again, it being understood that one finished package is delivered at the forward end of the machine as each complete intermittent operation` of the parts of the machine occurs, the dead movements occurring as the cranks are verse bar passing the far and near dead centers, thus being of short duration for speed in production.

'Ihe sealing plate |85, may be and preferably is of heavy metal for its gravitational sealing value and, as best shown in Figs. 6 and 11, may carry sealing bars |90 near its sides and a trans- |9| at or near a central position of its length and on its underface, and these bars are made adjustable to coincide with various size packages by bolts |92, fixed in slots |93. Of course two or more transverse sealing bars may .be employed if desired andy more than two longitudinal sealing bars may be used if the nature of the work demands it.

Preferably, thesealing plate |55 may be cut to produce a Iguide notch |94 at either side to receive the bearing blocks in vertically movable relation. I

Figs. l, 2, and 7 disclose'more or less diagrammatically, belts which may be employed in the operation of the packaging machine.

These belts may all be driven from the motor shaft through transmission rolls or pulleys if desired.

The most important are shown or indicated as package supporting belts |95, driven as at |96 from the motor 55, and which after acting as means for supporting the web train of packages toifthe sealing station, are passed between direction rollers |91, to a lower level, to function as out-carriers or conveyors for delivering the nished products to a remote point for packing or storage. These belts may be carried out as far yas desired, over a pulley and returned to traverse a general drive roller |98. Other belts |99, in Fig. 5, driven from the same source, may be employed for carrying off the waste trimmings cut from the edges of the webs for making up the packages.

The rack bar 35,is appropriately connected to the base table |68, or to one of the slide plates |58 of the carriage |51, and is operated thereby through a suitable groove 202, formed with the side rail of the frame, or said groove may be formed by bolting a properly formed rail 203, (see best Fig. 2) to the side rail of the frame l0, said gear rack 35 being effectively heldin its groove by the overlapping gears 60, |30 and |48, and by its connection to a part of said carriage.

A pull-spring 204, draws the roller |31 into constant contact with the shoulder |38 of the master gear 10.
