My invention relates to packaging machinery of a type particularlv suitable for completing the packaging of such articles as rolls of exibie felt rooiing. It includes among its objects and advantages, a reduction in the complexity and number o parts involved, 'and simple and quick ady justment means for. taking care of rather wide variations in the size of the package.

In the accompanying drawings:

Figure l is a side elevation partly in section of a machine according to the invention;

Figure 2 is a planview as on line 2-2 of Figure 1;

Figure 3 is an enlarged cover applicators;

Figure 'l is a view oi the axial insert mechanismasonlined-ofrigure l;

Figure 5 is a section along the axis of the main article carrier as on line .5 5 which appears in FigureZandinlgure 1; and

Figure 6 is a detail section as on line 5-5 of Figure 5.

in the embodiment of the invention selected for illustration, the machine comprises a structural frame made up of angle end beams l@ and side i2 and preferably supported on caster wheels hl. Substantially the right haii oi the frame as seen in Figure l is occupied by the main article carrier and associated parts which are supported on side plates l. The left end of the machine is occupied by the paper magazine carrying the stach of wrapping paper i8. I provide a slightly inclined track or ruirvs'a,y extending the entireA length of the machine and interruptedvonly adjacent the main article carrier where the articles are picked up and ,transferred from the section oftrack leading into the main article carrier to the delivery section 2i! best shown at the right end oi Figure ll This track is formed in part by the stack of wrapin'ng paper i8 itself and completed by the incoming section 22 and the middle section 2d. as indicated in Figure 2 I prefer to unite the sections 22 and 2d by side members 2S lying on either side of the wrapping paper lsection of one of the end Y stack i3.

In Figure 1 I have indicated one o the articles to be packaged 28, on which as yet no operation is being performed. It will be .obvious that the section 22 may extend to the left indeiinitely and i that an indefinite number oi articles -23 may' lie inserting mechanism of Figure 4; the mechanism for applying adhesive to the wrapping paper; the escapement for periodically admitting an additional article at the proper time; and the main carrier for picking up the articles and spin# ning them to complete the packaging.

Adhesive application and wrapper pickup Duplicate paste pots 3B are suspended pivotally on the ends of duplicate arms 4Q rigid with parallel shafts d2 and dd extending across above the path o the articles as they roll down the track. The shaft c2 is connected with the shaft d4 for rotation in unison therewith by the drag link 5S pivoted to the ends of duplicate arms 68 on the'two shafts. Each paste pot contains a charge of iiuid adhesive and at its bottom a dis pensing roller 5B provided with a projecting tip 52 positioned to contact the top wrapper I8 and lift the roller 59 slightly in the paste container. This shifting movement each time the parts move into the position o Figure l causes a predetermined amount of adhesive to work down under the roller ed, and as the paste potis lifted again the movement of the roller 5d back intocontact with the bottom oi the paste pot will expel a predetermined amount of adhesive through suitable openings along. the bottom of the paste pot. In this way the lower outside surface oi the paste pot receives a predetermined increment of adhesive during each cycle of operation, and movement of the paste pot down into contact with the paper as shown in Figure l will apply adhesive in narrow lines roughly indicated at -in Figure 2. The shafts #2 and #l are given a reciprocating rotary movement by means of an arm 5d connected by a pitman 55 to a short crank El projecting from the end of the shaft 3%.

It will he apparent that such a roll as 3B in Figure l, when released by an escapement to be described hereinafter, will roll down of its own Weight from the position shown in Figure 1 directly over the paper i8. As this roll strikes the rst line of adhesive '5d it will adhere to and piek up the upper edge of the top wrapper, and

its own rolling movement will lroll the wrapper around the roll until the covered roll engages the lower paste line 5d. At that point paste at the lower edge of the wrapper sticks the lower edge of the wrapper to a previous convolution of .the same piece' of paper and the roll moves on and into the positionv oi the roll indicated in Figure 1 at 32 with a complete peripheral wrapping. As

` clearly indicated at 55 in Figure 5,-this peripheral roll itself.

wrapping does not extend beyond the ends or the Escapement Rigid with the shaft s2 is a release rever ss which constitutes the primary escapement for releasing the roll B at the proper time. Rotation of the shafts 42 and 44 in counterclockwise direction from the position of Figure 1 will move all the arms 40, 43, and 33 and lift the paste pots 33 far enough to clear the roll 33 as it slips out from under the release arm 33 and rolls down the track. Also rigid with the shaft 42 is the hold back segment 30, which will move down in front of the roll 23 simultaneously with the lifting of the release arm. 33 and block the forward movement of the roll 23 until the parts come back again almost to the position of Figure 1 at which time it will move high enough up to let the next roll roll down against the arm 33.

Inserts It is customary to sell roll roofing with a small package or carton of roofing nails and a small can of roofing cement housed inside each roll. The camshaft 32 (see Figures 1 and 4) is driven at the same speed as the shaft 33 by suitable means such as the sprocket 34 on the shaft 33 connected by the chain 33 to the sprocket ratchet |22 axial with and integral with the adjacent gear |33. A suitable holding pawl |24 completes the transmission.

spinning The main article carrier comprises parts I mounted for simple rotation and for planetary rotation about the transfer shaft |23 which is driven from the shaft 33 at one-fourth the speed of the shaft 33 as by means of the sprocket drive -at |23 and this shaft is journaled in the stawith sleeves 33 rotatable on the sleeves |33.

33 on shaft 32, and supported from the main frame in any suitable way as by bearing brackets 13. At each end of the shaft I provide an actuating lever 12 journaled on a fixed stud 14 and carrying a contact roller 13 pressing against the edge of an annular cam 13 mounted on the end of the shaft 32. At either end of the roll 33 I provide a magazine 13. vOne of the magazines may contain cans 13 of rooting cement and the other magazine may contain packages 11 of roofing nails. At the bottom of each magazine I provide a window 33 positioned to register with the hollow space at the center ofthe roll 33 when in the position of Figure 1. The upper end of the lever 12 is bifurcated at 32 to engage and actuate the pins 34 integral with the followers 33 which are resiliently pressed toward the center of the machine by springs 33, both fillers and springs being housed in suitable housings". At the moment when the shafts 42 and 44 pause in the position of Figure 1 because the crank 33 is on dead center, the steeply inclined surface portion 32 of the cam 13 moves across in front of the roller 13 and the spring 33 is permitted to expand and expel the lowest insert 'I3 or 11 into the roll 33. Thereafter, while the roll 33 goes on its way through the machine, the gently inclined cam surface 34 forces the lever 'l2 back into the position of Figure 4 and the stack of inserts in each of the magazines 13 drops down ready for the next cycle of operation.

Wrapper feed |33 (see Figure 2) driving a large sprocket |33 on a suitable countershaft. The large sprocket 33 is integral with the small sprocket 3 which drives the large sprocket ||2 on the shaft 33. The sprocket ||2 is free to rotate on the shaft 33 andis integral with'the eccentric ||4 which actuates the eccentric rod ||3. rod ||3 reciprocates the lever ||3which carries the pawl |23 Vengaging the teeth of a large The eccentric Each pair of spiders carries four' planetary roliers |33 rotatable on axes parallel to the axis of the shaft |23. All eight of the planetary rollers carry pinions |43 at one end and all these pinionsmesh with a gear |42 suitably driven from the shaft 33 at substantially the same speed as the shaft 33, as by the sprocket drive |44. With the two sets of spiders rigidly locked in the relative positions illustrated in Figure 1, it will be apparent that all the planetary rollers |33 will be in rotation counterclockwise as indicated bythe arrows in Figure 1, and that the roll 33 coming down the track in clockwise rotation will move into a position just a trifle lower than the position indicated at 32 in Figure 1, if the parts are properly timed, and will be continued in its rotation by fits contact with the planetary rollers |33 while it is carried from the position at 32 in an arcuate path around the axis of the shaft |23 to the discharge position at |43.

` Edge wrapping Adjacent the path of each end of the spinning article 32 on its way to position |43 I provide a holder |33. 0n this holder I provide first. a

operaia series oi idle rollers |10 for applying edge tape. The-tape is housed ina suitable supply roll at H2 and drawn over the roller |16, which dips into the adhesive bath at |16 and applies adhesive to the tape. It then passes down and around the rst roller il@ being held in contact therewith by an idler |18. It will be apparent of Figure 1 past the various rollers |10, it will wind the tape |12 around itself. When the article has progressed to substantially the next to the last roller |10, it may complete a suitable electric contact |19 to actuate the solenoid i80,

which solenoid actuates a lever pivoted at 82, which lever carriesa cutting knife |84 at its left end. The actuation of the solenoid will.

throw the cutting hilfe down to strike a sharp blow against the article and sever the tape H2.

A It will be apparent that the position of the knife i3d is such that this severance will leave a short reach of tape hanging down between the idler roller V10 and the adjacent roller |10 ready tov naled in vertical slots in the carrier plates.

|92 so that they rest by their own Weight on the article and are rotated by frictional contact therewith. y tube |90 carrying metal heads |96 at its ends and felt discs |88 projecting beyond metal heads 196. The Whole is journaled on the pivoted shaft 200, the ends of which ride in the slots i60; It will be apparent that as the article moves under the two rollers |87, the projecting portion of theA tape at |86 will be spun down into the position indicated in full lines inA Figure 5.

lI'hev tape |2 is cut on a bias so that it folds down readily without material or objectionable wrinkling or folding. To make' sure that the felt discs |08 do not stick to the tape, at least the rst discs |88 are provided with a stationary separator blade. I have indicated said blades for both sets of discs |88. The blade proper has its sharp leading edge positioned as indicated at |0| in Figure l. The body of the blade at |83 lies against part ofthe working face of the -disc |88, and vwhen'a roll 32 is present its other face may have light sliding contact with the tape H2. member |85, journaled at |81 on the rod 200, and prevented from rotating by a, rigid nger |89 entering a vertical slot |9| in the supporting plate |68. l

To take care of rolls 32 of dierent sizes, the plate |68 lhas end lugs |93 overlying stationary bosses |95 on brackets projecting from the end plates I6, and' is guided in vvertical adjustment between the bosses |95 by vertical edge portions |67 contacting the bosses. Set screws |99 enable the operator to raiseand lower the plate |68 to position it uso that the roll 32 will press against the idler' rollers |10 with an adequate force. The yweight' of the plates |68 and of the parte carried by the plates may be made such as to generate the exact force desired for the wormng pressure of rollers |10, in which case the operator adjusts the set screws |09 sothat each roll 32 barely lifts the set screws off the bosses |65. Thus the force used is accurately determined and if any individuali-oli 32 should happen toy be Each crimping roller comprises a The blade is supportedby a frame.

-'that as the article 32 moves from the position y a trie oversize, it will be handled without difnculty, as the plates 68 will merely be lifted an additional fraction of an inch as that particular roll 32 passes under the idle rollers |10.

End covers Before the edge tape |12 is applied, I position a cardboard cover disc 202 over each end of the article. The container 204 Vfor the discs 202 is shown in Figure 1 and its position is indicated in'dotted lines in Figure 2. To transfer one of the discs 202 from the container to the end 'of the article, I provide a carrier plate 206 rotating in unison with the shaft |26 and carrying four'- projecting head 2|8 extending beyond the'housing 2 l0 for contact with actuating cam members to be described hereinafter. The plunger is actuated by suction supplied through the connection at 220 forming part of a manifold 222 in open communication with ports 224. In the position of rest indicated in Figure 3, the ports 220 are covered by the end 226 of a half length sleeve 228, which end is provided with a pair of piston rings 230 to improve the seal. From the annular space between the housing 2|0 and the sleeve 228, vacuum becomes effective insideT the entire housing through ports 232 communi,- cating with the main space inside the housing; and the same suction is effective inside the tubular plunger rod 2|2 byreason of ports 230 inthe plunger rod. At lts front end the plunger rod 2l2 passes through a suitable packing 236 and at its outer end carries a exible suction cup 238 suitably swiveled about the axis of the plunger as by meansjof a metal ferrule 260 riding'under the ange 222 'of a metal ring heldA in place on the end of the plunger by the nut 2&6. The hollow rod 2|2 is open at its right end, as seen in Figure 3, so that only partial suction is effective in housing 208 by the throttling action of ports 236, until e. cardboard disc covers the cup 230 and completes the seal.

Referring now to Figures. 2 and 5, as each picker comes-into register with the end cap 202 it isl cammed axially toward the center of the machine by suitable means such as the cam 266 mounted on the stationary end plate |6. This initial displacement uncovers the ports 226, and the plunger immediately moves over and thrusts its suction cup 4against the adjacent piece of cardboard. Continued4 rotation of the plate 206 carries the piece of cardboard up almost to the position indicated at 32 in Figure 1, and during this movement of the plate 206, further inward movement of the plunger is restrained by a second cam 238the edge of Awhich lies in front of the head 2|8. At or a trifle above the position 32 as the tape |12 is starting to wind onto the article, the head passes out beyond the enduntil after the rollers |88 have completed the edge seal and wrapped the tape down over theedge of the disc 202. Thereafter, at any convenient point between the last roller |88 and the position of the-article at I, the suction delivered to the connection 220 is cut oit and the picker promptly movesY back to retracted position under the force of spring 2H ready for a .through suitable apertures in the plate 258.

Each connecting tube 250 is in communication with an L-shaped passage 264 debouching at the valve 258 receives suction from any suitable source through a conduit 266 which communicates with an arcuate valve port 268 to deliver contact surface of the manifold 252, and they suction to the conduit 250 beginning slightly bel fore the time when the cam 246 kicks the plunger into operative position, and continuing throughout the movement of the picker past the cam 2&8 and the rollers |81.

It will be obvious that while I have illustrated rolls of roofing and wrapping paper suitable for such rolls, the principles o f my invention are applicable to the packaging of articles of all sorts and sizes, including such items as foods, and pharmaceutical products in all sizes, and such wrapping materials paper.

Without further elaboration the foregoing will so fully explainmy invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service.
