Application ined my zo; i923.' serial no. 652,763.

To all whom z't may concern:

Be it known that I, CESARE BARBIERI, a

subject of the King of Italy, and a resident vented certain new and 'useful Im rove` of the city of New York in the county of New York and State of Nzew York, have inments in a Machine for Forming and luing Paper Cups; and I do hereby declare that l the following is a full, clear, and exact descri tion of the same, reference being had to t e accompanying drawings, and to the numerals of reference marked thereon, which form a part of this,` specification.

This invention relates more particularly to an improved automatic papercup forming machine and more particularly to mechanisms for the machine whereby paper cup blanks `are automatically fed singly into the machine and into the field of operation of an adhesive applying pad which acts at a predetermined-time to apply adhesive to a portion of the blank in a determined conlfiguration, afterwhich the blank is advanced between forming dies one of rwhich is spirally grooved so that while the blank is being wrapped around the other die the margin of the adhesived portion of the blank is not pressed against the main portion of the blank, thereby causing a paper cup to vbe formed wherein none of the adhesive is squeezed out from between overlapping' portions of the formed cup.

l It is an object of the invention to provide an automatic adhesive applying mechanism for a paper cup forming machine whereby adhesive is applied Jto a blank at a predetermined distance from one of the margins thereof so that when the blank is formed.

into a cup the adhesive will not be pressed out from between the overlapping portions of the blank.

It is also anobject of the invention to -provide a cup forming machine lwherein the cup blanks while being advanced toward .the forming dies are'acted upon by an adhesive 'applying pad which acts to applv adhesive to the blanks in apatch of a predetermined shape and at a distance from one of the margins thereof so that when the blanks are shaped into cups and stacked they will not stick to one another due to portions of the adhesive being squeezed out from between overlapping portions of the blanks.

It is a further'object of this invention to grooved to prevent pressure from being ap -plied to the edge of the adhesivedmargin of a cup blankbemg formed into a cup around the other of said dies. v

Still another object of the invention is to provide a cup forming machine wherein a blank after bei-ng removed from a magazine is stamped b an adhesive applying' pad and then grippe by a gripping mechamsm and' transferred to a lower level onto a reciprocating table. below resilient retainers to be advanced between forming dies and formed into acup thereby.

It is a further object of the invention/to provide a cup making machine wherein formed glued cups, when discharged from 'forming dies, are deposited to fall through a curved chute before reaching a cup stacking tube to afford time for the glue to set v before the formed cups are nested one with in the other in a cup holder which is adapted to be lowered within the stacking tube each time a formed cup is delivered thereto.

Another object of the invention is the construction of a cup forming machine provided with an vadhesive supply rolleragainst'A which a rotatable reciprocating adhesive distributing roller is adapted to engage to receive a supply of adhesive and then roll vover a reciprocating pad which is adapted to stamp a cup blank with a film of adhesive before the cup blank is advanced between the cup forming dies of the machine.

It is also an object of this invention to provide a cup making machine with a cup stacking mechanism having la long chute through which the finished cups pass before entering a stacking tube in which a cup re v ceiver is adapted `to be automatically lowered each time a cup is received, said chute being provided with a pivoted shutter adaptedvto close the Vlower end of the chute when in closed position to form a stop for cups in order that a stack of cups may be removed ingfmachine embodying the principles o of the machine.

yfrom ythe stacking tube without necessitating -tion to stampa cup blank with a film of adhesive in advance of the actionof a transfer mechanism which .transfers the adhesivedl blankonto a reciprocating table which advances the blank into the field of operation of cup forming dies.

Otheri and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawings.

The cu forming dies 8 and 15 areseparated atthe 'eginningf ofa cup forming operation due tothe action of the cam 10 on the beveled roller 11.

A stack of prepared cup blanks, of a shape similar to that illustrated i dotted lines in Figure .1, is placed in the -blank holdin magazine between the upright guides 71 and 76 with the lowermost lcup blank resting upon the bosses 72 and yupon the arms79.

f Theblanks are so shaped that they-v clear the inclined guide plate 77. 'The delivery yof a cup blank from the bottom of the stack is accomplished by means of the krotatablefeed reel 6ft-67 which carries thefriction pads I i 68. The feed reel is rotated by the gear 64 vwhich is in mesh` with the` gear 62` on lthe shaft 61 on which the beve ed gear 60 is mounted to be o erated by the beveled gear 59. The bevele gear 59 is'operatedA from the gear 53 which isdirectly'm mesh with the large gear 7 operated by the drive gear 6 on the shaft 3. When the feed reel is rotated, the friction pads .68 thereof are brought into contact with the bottom surface ofthe lowermost cup-blank,and'slidesaidy blank from the magazine between the feed rolls 101 andl102.l As the 'blank isjb'eing removed from the 'magazine the trailing A tip thereof is rstpulled out ofengagement inclined guideV pla-te 77.The .,lowrmost blank in the' magazine is l thus delivered tov thez'feed` rollers and the fstacko'f blanks falls operated by the gear, The cup blank received *between thefrollers 1101 'and-"102 ,is y

fed' forwardly v therebyy v ontovffth'e/ 'station-ary table 33 and beneath the guide-p "teil3v'5`on which the electric heater 1100;".isf mounted. As the 'cup' blank is dfed onto thestaltionary table one edge of 'the'cup' blank lslides along `the'-- guidey bar 111 until therad-vance Aedgevof the cup blank.I comes into contact with the'stop bar 112.l The cup blank is thus properly centered on they stationary table with a portion of thejcup blank on which glue is to be applied disposed over the table opening 34 in the field-of operation of the glue applying pad 1213. .v

The glue is carried in the tank in which the glue feed roller 123 operates. The glue feed roller is rotated from the shaft 61, `the chain 129 and thel gear y1,28v whichv rotates the shaft l124v on whichA the feed roller is mounted. Excess glue carried upwardly by the feed roller from lthe glue box 122 1s scraped from the roller by means of the scraper blade 130./ The' scraper blade.`

130 is adjustable with respectto the feed roller by means of the. tapered screws 134 which coact with4 the beveled block 133 secured on the scraper blade.

At this stage inthe operation the glue applying pad 113" is in its lowered,y position .(Fig. 16)v and thepad gluing roller'158 is thereby vactuating the arms 154 to cause the blocks 155 to slide forwardly on the guide rods 156 and thereby advance the'roller 158 which is caused to rotate vwhen the Vroller 159 comes in contact with the angle rail 160 (Figure 9). The advancin andi'rotating roller 158 isV thus advance ,"ofver the.- retracted pad 113 into contactwith the rotating glue feed roller 123. The roller- 158 isv thus supplied with a coating of glue and 4the arm 145 is positioned to cause an upward swing of the levers 141 thereby elevating the toggle member 140 and causing the same to push the bracket plate 115 upwardly. The glue pad 113 is thus advanced' upwardly through Vthe table opening 34 and stamps a film of glue on the under surface of the cup blank which is heated by the heater 100 so that the glue will readily adhere thereto. The shape of the film' of glue is. of course similar to the shape of the pad 113 as illustrated in Figure 6l and is apjied to la particular portion of the cup With lthe application of the'film ,of glue to the cup blank, the pad 113 is retracted. The glue stamped cup blank is'now ready to be transferred from' the stationary table f 33 onto the'reciprocating table 31. When the dies 8 and 15 are rotating the table 31.

is reciprocated by means of the -lever 30. The lever 30 is'oscillated from the shaft 26 which is rocked back and forth by the crank arm connected eccentrically by the link 24 to the gear 7 to receive a drive therefrom. Whenla glue stamped cupblank is on the stationary table 33 the table 31 starts to move. back permittin the spring controlled stop arms 191 (lgure 6) to swing upward1` into a vertical position by the" action o the spring 193. The lever now acts to gradually retract the table-31 bencath the stationary table 33.r Asthe table 31 moves into its retracted position the crank arm 173 acts on the-connecting..rod

' 174 to swing the bell crank 175-176 from j position upwardl face of the cup b ank to clamp a portion of the dot-ted Iline position of Figure 10 toward the full line position thereby causing the rack 182 to act on the gear segment 183 to move the lower gripper jaw 187 into closed against the bottom surthe cup blank between the gripper jaws 187 and 188.l After the jaws are closed the bel] crank 175-5-176 acts on the curved arm 186 onto the supporting fingers 39 free from contact with the table and alittle in advance by causing the presser arm 194 to swing up v wardly away from the table 31to permlt t e cup blank to be moved beneath the s amel lVith thevad- Vance of the `table 31, the action of the camv of the sto-ps 40 and As' the blank lis transferred onto the reciprocating table 31, it is conducted beneath the -tips of the resilient arms 194 and 195 -Which frictionally` contact the upper surface of the cup blank to pull the cup blank backwardly against the

stops

40 and 44 when the table 31 startsto ad- VanceI thereby properly centering. the cu blank on the table. being transferred onto the table 31 the cam .202 (Figure 7) acts on the vroller 201 to When the cup blank 1s cause the shaft 198 to partially rotate there- Y onto the reciprocating table.

202 permits the presser arm 194 to be lowered into frictional engagement with the cup blank. In addition to

thespring arms

194 and 195 which act to pull the cup blank into a centered position on the table 31, the upright arms 191 also act to push the cup blank backwardly on the advancing table andare then' lowered by theadvance end of said table which passes over the same. The centered cup blank is now advanced into the field of operation of the dies 8 and 15 to be gripped thereby as the table 31 again starts to move back. As the advancevend of the cup blank is projected between the separated dies 8 an. 15 the raised portion of the cam.10rotates away from the roller 11 thereby permitting the sleeve 12 to be lowered so that the presser die 15 moves downwardly toward the forming die 8 clamping the advance portion of the cup blank between the dies. The cup blank is thus automatically fed into the'fi'eld of operation of the forming dies.

The cup forming die 8, the main portion of the blank firstbeing formed into a cup' around the die 8 after which the glued portion .of the blank is graduallyl wrapped around the body of the cup to reinforce the same. As the glued port-ion of the cup blank is Wrapped around the conical cup, the spiral groove 16 of the presser die 15 engages over the margin 17 Figures -18 and 1,9) of the cup blank thereby preventing any vpressure from being applied'to said margin 17. The glue is accordlngly not pressed out from below the margin 17 and sticking of the formed cups, one within the other, is thus obVated. The

.completed cup is thus/,formed on gthe die 8 ready to be automatically discharged from the forming. die by'a blast of air from .the air, pipe 2 03 similar to the arrangement disclosed in my co-pending application for Patent Serial Number 259,986 for anAutolnatic cup forming machine filed October When a cupis inished the presser die 15 is of course first separated from the forming blank is now formed around the llll die bythe action of the beveled cam on the roller 11. The cup being released by the resser die itis discharged fro-m the formlng die and falls into the curved chute 5,204 and then enters the top of the receiving tube 205 to be received by the cupI holder provided within the tube and supportedon the end of the movable arm 206. The curved chute 204is provided to afford a long path between the forming die 8 and the cup stacki ing tube 205 so that therewill be a short i lapse oftime sufficient to permit the glue to 205 the movable supporting arm 206 is lowset before the cup enters the stacking tube 205 and is pressed against other cups within the tube.y

Each time a cup is delivered into the tube ered a predetermined distance by the action f of the bar 218 which operates the pawl217 and the ratchet wheel 216. VVhenfthe tube v is filled by a stack of nested cups the shutter A207 is moved into closed position across the bottom of the chute 204 to receive cups while the stack of cups in the tube 205 is removed.

' It will thus be noted that the machine need not be stopped during the time the tube 205 visemptie pull the latch bolt 94 from the full line position ofy Figure 13 into the d'otted'line release position of said figure. The plate is thus readily released and may be swung upwardly by means of the handle 88 about the shaft 87 ,(Figure 15) until the pin 86 strikes against the bar 82. When the plate 35 is yswung upwardly the cam block 84 acts against the pin 83 thereby pulling the bar 82 forwardly. Forward movement of the bar 82 acts to swing-the crank armq81 upwardly to partially rotate the shaft 78 where by the lifterarms 7 9 (Figure 1) are swung upwardly to raise the stack of cup blanks in the blank holding magazinefout of the field of operation of the blank feed reel pads 68 .80 thatno c'up blanks willfbe delivered from 'the magazine to thevblank feed rollers 101 and 102 when the plate 35 is raisedand the machine continues operating. l

\Forward movement of lthe bar 82 also' causes the crank arm 170 on the sleeve 80 vto swing downwardly from the position illustrated in 'Figure 2 to lower the rod 171 and push the flattened lower end thereof in fro-nt of the stop screw 163. The lower end of the rod 171 is thus positionedto be contacted by the boss 162 on thecrank arm 161F thereby shortening the forward throw of the levers 153 on the shaft 142 so that the arms 154 will not move the glue applying roller l 158 forward far enough to come into contact' with the glue feeding'roller 123. No gluefrom the roller 123J is distributed to the glue applying roller 158 when the' plate 35 is ralsed.

It will be noted that rwhen 1t becomes necessary to raise the blank guide pla-te 35 that the cam block 84 automatically acts to cause elevation of the cup blanks inthe magazine so that the feed of cup blanks into the machine is discontinued aswell asthefeeding of glue tothe roller 158 and fromsaid roller to the glue stamping pad 113.,

I am aware that numerous details ofconv struction may be varied through a wide .range without departing fromthe principles of this invention, and I therefore do not pur pose limiting the patent granted otherwise one of said dies having a spiralgroove'therein to engage over the margin of the ad-l hesived portion of the cup blankl so thatno pressure will be applied to saidmargin during the forming of the cup.
