Application November 27, 1946, Serial No. 712,552

This invention relates to apparatus for assembling linings in receptacle closure caps, the linings consisting of disks severed from a web of suitable material, such as heavy paper.

It is an object of the invention to double the production of assembled receptacle closure caps without increasing the size or cost of manufacture of the apparatus now in use for the same purpose.

It is another object of the invention to feed closure caps onto diametrically opposite portions of a rotatable closure cap support by a pair of conveyers and removing assembled closure caps from the rotatable support onto one of the pair of conveyers andonto another single conveyer to discharge the assembled closure caps from the apparatus.

It is a further object of the invention to provide an apparatus wherein the travel of the closure caps from the point of delivery of closure caps onto the rotatable support to the point of discharge of assembled closure caps from said rotatable support is less than 180.

Another object of the invention is to provide independent adjustment of a pair of endless belt conveyers and a single endless belt conveyer to vary the lengths of said conveyers.

A further object of the invention is to provide a reciprocatory head yieldingly counterbalanced against the weight thereof to prevent said head and punches carried thereby from assuming an undesired position when the apparatus is stopped.

Other objects and advantages of the invention will hereinafter appear in the detailed description thereof.

In carrying out the invention shown in the accompanying drawings, there is provided a table I having legs 8 at the opposite ends, as shown in Figure 2, for supporting the operative parts of the apparatus in elevated position.

The operative parts of the apparatus are actuated from a suitable source of. power shown as an electric motor 9 mounted on a platform l0 supported below the table by a transverse member of the legs 8 at one end of the table. The electric motor is operatively connected to the operative parts of the apparatus through a drive shaft I l directly connected to the electric motor by a belt l2 and rotatably supported below the table 7 by bearings I3 suspended from the opposite ends of said table.

Closure caps C into which linings are to be assembled are supplied by a pair of hoppers shown in a general way at M in Figure 6 and supported by a pair of standards I5 mounted on a bracket [6 fixed to the legs 8 at the end of the table opposite the end supporting the motor 9. As usual the hoppers have agitators, not shown, actuated from the drive shaft H through a belt I! engaged around a pulley I8 on a projecting end portion of the drive shaft and. pulleys l9 fixed on the shafts of the agitators. The closure caps are discharged from the hoppers l4 through a pair of chutes 20 communicating at one end with the hoppers to receive closure caps therefrom and the opposite end discharging closure caps onto the upper stretches of a pair of endless belt conveyers 2 I, 22, as shown in Figure 6, to be delivered to assembling means to be hereinafter described.

The endless belt conveyor 2| is supported between drums 23 and 24, drum 23 being rotatably supported between the legs of a U-shaped bracket 25 having one leg portion supported by a base 26 slidably mounted on the top of table I by a bolt 27 screw threaded in the table and engaged in a slot 28 in the base of the bracket, whereby the length of the endless belt conveyer 2| is varied end. of the table on which the hoppers M ar 3 mounted, the drum 2:; being between the bifurcation legs of one of said brackets.

The other endless belt conveyer 22 is supported between drums 33 and 34, the drum 34 being fixed on the end portion of the shaft 3| opposite to the end portion supporting the drum 24 and between the bifurcation legs of the other bracket 32. The drum. 33 is fixed on one end portion of a shaft 35 rotatably mounted at said end portion in the end portions of a pair of arms 35 extending on opposite sides of the endless belt conveyor 22 and having the opposite end portions slidably mounted in brackets-3l fixed on top of the table 7 to permit adjustment of the drum 33 toward and away from the adjacent end of the table to vary the length ofthe endless belt conveyer 22. The arms 36 are retained in adjusted position by set screws 38, ;as shown in dotted lines in Figure l.

The endless belt conveyers 2! and 22 are continuously actuated from the drive shaft ll through a belt 39 engaged. around. a.-.pulley.:.4t fixed on the drive shaft and a pulley 4i. fixed .on a shaft 42 having onerend portion slidably-and rotatably mounted. in a bearing. 43 fixed'onltop of the table F. The opposite end portion ofthe shaft 52 is rotatable in bearings mounted on one of the adjustable arms 35 .and retained against longitudinal movement. in saidbearings 44 by collars l secured on said shaft onopposite sides of one of the bearings 44, so that the adjustment otthe arms 33 in the brackets 31, will move the shaft 42 therewith and the shaft sliding in. the bearing 43. The end portion of :the

shaft :2 projecting from one of the collars 45 is operatively connected to-theudrum 33 of the endless belt conveyer 22 through a beveled pinion .43 fixed on said projectingend ofthe shaft 42 and meshing with a beveledgear l'i fixed on the portion ofthe shaft 35 extending from the inner arm 33, as, shown in Figure 1-. The pinion 63 and gear 4'! are .enclosed in a housing 48 .carried by the. adjacent arm 35 and hearing.

The closure caps C are retained on the upper stretches of the .endless belt conveyers 2i and 22 from' the discharge .ends of ,thechutes 2B toan intermediate portion oi-said conveyers by guide rails; es adjustably supportedpn the opposite sides of the conveyers by rightangular members 5i) adjustably mounted in .a bracket 5-] fixed, to

thetop of thertable l.

The travel of the closure caps on the upper stretches of the endless belt conveyers -21 and 22 is stopped by abutment plates 52152 adjust .ably mounted on plates 53, 54 supported ontop of the table l to extendin-spaced parallel relation to said table top and over the upper stretches of the conveyers. The abutment plates 52,52 are adj-ustablymounted on the plates 54 by. screws the standard 58 resting on the top of :thetable i and secured thereto by'bolts 5!, as shown in Figure 2. The flange 58 also rotatably supports the hub member 5? and the hub member is retained on the flange 68 by aring EZengaged on --thecylindrical standard 53. Theiscrew threaded 4 connection between the annular member 55 and the hub member 5'! permits adjustment of the annular member for closure caps of different heights. The annular member 56 is arranged with pockets for the engagement of closure caps therein to retain the closure caps in equidistantly spaced relation On the annular member 56. Said pockets are formed by a series of arcuate segments-=53 of a number to form a circle mounted on the upper end of the hub member 51 by v screws 64. The segments 33 are arranged with a series of arcuate recesses 65 corresponding to the curvature of the closure caps and equidistantly spaced around the periphery of the segveyers' 2| and. 22 to receive closure caps from said conveyers.

The rotatable support is intermittently actuated to successively ;.-pcsition the recesses or .pockets sdrelative to. the conveyers. 2 Land-22 to receive successivelclosure caps' fromf saidponveyers. The rotatable support is actuatedffrom sive recesses 7 equidistantly spaced around and radially extending inwardly from the periphery of a disk'lzlfixed. on one end of a shaft i3 rotatably mounted in bearings 14 on the underface of the table 3', as shown in Figures Z and 3. The opposite end of the shaft 13 is operatively connected to the rotatablesupport 55. live. beveled Pin on l5 meshing with a beveled annular gear l5 fixed to a laterally. extending flange ll of the hub member 57, as shown in Figure. 2. To hold. the disk .72 againstrotation during the periods of rest thereof concave faces 13 011 the periphery of said disk, between. therecesses. H are successively engaged by corresponding convex faces 19 at theoppositeends of a member 83 fixed to the face of thegear wheel 68 arranged with the pins Biland rollers it and said'member 85' having con- .cave sides St to permit movement of the disk f l2when. the pin 68 and rollers '19 are engaged in one of the recesses 1!, as shown in Figure 3.

The Genevamechanisni isenclosed in a protective shield 82 supported by the table l, as shown in Figure 3.

7 During. the periods of rest ofthe rotatable support 56 diametricallyop posite pockets are positioned in. alinem-ent with the closure caps engaged by the abutment plates'52, 52 as shown in Figure l, to simultaneously receive said jclosure caps from the conveyers 2i and 22. Said v closure caps are simultaneously transferred from the. conveyers 2i nd 22 into the ali ned pockets B5 by 1ike means so that a description of one will besufilcient to understand the structure and operation of both. .Said closure cap transferring means comprises a carrier block 83 slid- .ably mounted in a slideway 3 3 slidably supported connected to said carrier block by a pin 81 fixed in the carrier block and engaging in a slot 88 in the plate 86 to impart movement of the block to the plate in a direction toward the conveyers 2| and 22 and the rotatable support 56, and by a set screw 89 adjustably mounted in a depending portion of the plate 86 to abut the block 83 and impart retrograde movement of the block from the conveyers 2I and 22 and the rotatable support 56 to the plate 86. The set screw 89 is yieldingly maintained in engagement with the block by a spring 99 fixed at one end to the pin 81 and at the opposite end to a pin 9I fixed in and projecting from the plate 86, as shown in Figures 1 and 3. Reciprocation is imparted to the carrier blocks 83 from the drive shaft II through a gear 92 fixed on the drive shaft and meshing with a gear 93 fixed on a shaft 94 rotatably supported in bearings 95 suspended from the table I, as shown in Figure 2. Rotation of the shaft 94 is converted into reciprocation of the carrier blocks 83 by an eccentric 95 fixed on the shaft 94 and encircled by a strap 97 connected to one of the carrier blocks by a rod 98 secured at one end to the strap 91 and adjustably connected at the opposite end to a collar 99 pivotally connected to one end of a lever I89 pivotallysupported in a bracket I9I mounted on the table "I relative to the. mounting of the slideway' 84, as shown in Figures 1 and 3. The opposite end of the lever I is pivotally connected to the carrier block 83 by a link I02, as shown in Figure 3. The other carrier block 83 is operatively connected to the strap 91 by a rod I93 pivotally connected at one end to the strap and adjustably connected at the opposite end to a collar I04 pivoted to one end of a lever I95 pivotally supported on a bracket I06 suspended from the table 7 in alinement with the slideway 84. The opposite end of the lever I85 is pivotally connected to one end of a lever Iiii' by a link I68. The lever IiI'I is pivotally supported in a bracket I09 similar to the bracket IIBI and the opposite end of the lever III! is pivotally connected to the slide block 83 through a link I II), as shown in Figure 3. By the lever connections IIIO, the carrier block connected to the eccentric 96 by the rod I93 will be reciprocated toward and away from the rotatable support 56 in synchronism with the carrier block connected to the eccentric by the rod 98. To prevent the closure caps on the conveyers 2| and 22 engaged by the abutment plates 52 and 52 from moving onto the rotatable support 55 during the retrograde movements of the slide plates 86 and causing jamming of the segments 63, said caps are engaged by a pin I94 fixed in and extending from the underface of an end portion of an arm I95 pivotally mounted at the opposite end portion on the slideways 84, as shown at I96 in Figure 1, and said pins I94 are yieldingly positioned in thepath of travel of the slide plates 86 by a spring I91 fixed at the opposite ends to an intermediate portion of the arms I95 and the plates 53 and 54. The transferring movement of the closure caps by the slide plates 86 will move the arms I95 on their pivots I96 against the force of the springs I91 and out of the" path of said closure caps, as shown in Figure The closure caps engaged in the alinedipockets 65 by the slide plates 86 are intermittently conveyed by the rotatable support 56gto lining assembling means in the form of a of punch and die mechanisms to sever disks from; a pair of webs III and position said severed disks into mechanisms. A pair of dies II2 having a web guide II3 are mounted in spaced relation over diametrically opposite portions of the rotatable support 56 by brackets I I4 secured to the top of the table I. A pair of punches II5 are ad-' justably carried by arms I I 6 extending from diametrically opposite portions of a head II'I releasably mounted on a cylindrical slide member II8 slidable in the cylindrical standard 58 and reciprocated from the drive vshaft II by an eccentric disk II9 fixed on the drive shaft; and encircled by a strap I29 having a crank arm: I2I pivotally connected at the free end to a; pin I22 mounted in the lower portion of the: The: standard 58 is arranged diametrically opposite.-

slide member I I8, as shown in Figure 2.

recesses I23 to accommodate the sliding move-- ments of the arms H6 and prevent rotation of j the head I I! and slide member I I 8. The punches: II5 are arranged with ejectors comprising a rodi I25 having a head I 25 yieldingly engaged with. a shoulder formed by the bore and cutting recess: of the punches, as shown in Figure 2, by a spring; I26 engaged on an end portion of the rods I245 projecting from the upper ends of the punches: and compressed between said upper ends of the punches and a collar I21 fixed on said projecting: end portions of the rods. After the punches; have severed disks from the webs II I and before the retrograde movements of the punches, the rods I24 are actuated to move the heads I25 into) the cutting recesses of the punches and remove the severed disks from the cutting edges of the punches should the severed disks or linings ad-- here to said cutting edges. This is accomplished by kicker mechanisms comprising rocker arms. I28 pivotally mounted intermediate the ends thereof on DQsts I29 carried by the head II! with one end of the arms adapted to engage the projecting ends of the rods I24 and the opposite ends adapted to engage adjustable abutments in the form of screws I38 mounted in the upper end of the standard 58, as shown in Figure 2, at the terminus of the cutting movements of the punches. The slide member I I8 and the punches II5 are actuated to sever disks or linings from the webs III during the periods of rest of the rotatable support 56.

It has been found that when the apparatus is stopped the slide member I I8 will have a tendency to assume its lowermost position under the force of the weight thereof including the head iII, arms H6 and punches II5, which will. require the turning of the drive shaft II by a hand wheel I3I fixed to one end' of the drive.- shaft should it be necessary to replenish the: webs I II in the web guides II3 by raising the: punches II5 out of said web guides. This defect; has been overcome by incorporating means in: the slide member M8 to counterbalance the; weight carried by said member. Said counter balancing means comprises a spring I 32 mounted. within the slide member H8 and compressed be-'- tween a cap member I33 mounted in the upper" end of the slide member H8 and a rod I34 fixed at the opposit ends in diametrically opposed? crank members.

wall portions. of the standard 58 and e rtended transvei selyfof the slide. member s through ametric y opp'os df l t' 5, n he. s ide m mber as shown in. Figure 2, The, strength of the spring I32 is substantially equal to the weight (if the slide member I18. and the elements car ried thereby, so that said weight will not force the punches U5 into the web guides H3 when the apparatus is stopped with the punches in positiori out of the web guides. The rod I 34 is positioned in thelowerfportion of the standard 53 the lengths of the slots 135 are suiidcient to permit unobstructed reciprocation of the slide memb r us. The". head Lin is mounted on the dr p. member I33. of the slide member IIB.

Predetermined lengths'of thev websj II are fedtojthe'di'es H2 and web guides I13 during the intermittent actuation of. the rotatable] support 56, and the retrograde movements of the punches I15 bytwo pairs of rollers I35, I31, roller" I3 ,'I "being fixed 'on a'shaft I438. rotatably mounted in arms I39 extending from the bracket I I I ,as shown in Figure. 4, with the rollers I 31 below'the webs III. The rollers I3 5 are fixed on a shaft Ill rotatable in the bifurcation leg portions of a bifurcated mounting member I iI pivotally mounteclbetween the bracket arms I39. The rollers I3Ii1and I3] are driven 'one from. the oth r by es n s a I42 and 3, fi the shafts [4p and I38, respectively. The rollers I35 I are normally maintained in engagementwith h v ups t. ace o t e w b H I by e Weight of saidrollers and gears [42, The rollers I36 arepos'itionedffrom the rollers I31 by pivoting the members I 4 I when it is desired to engage a' 'new web III between the rollers I36 and I31, The rollers I3ii and I31. are provided with scrapers. MA carried by the bracket arms I39 adjacent to] the rollers to. remove lint from said rollers, as shown in Figure l The gears are intermittently rotated from the drive shaft II through pawl and ratchet mechanisms, each of said mechanisms comprising a ratchet wheel I d5 fixed on a shaft I46 rotatable in bracket arms ISB and anadditional arm M 'I. The ratchet wheel is actuated by a'p awl I48 pivoted on a carrier plate I49looselymountedon the shaft IiIG and the'pawl yieldingly urged into engagement with the teeth of the ratchet wheel I by a spring carried by the carrier plate, as shownat I53 in Figure a. The carrier plates. hi9 are reciprocated to actuate the pawls I 28. into. and out of engagement with the teeth of the ratchet wheels I45. and intermittently rotate the ratchetwheels by 'a track member i5! fixedon' the opposite ends ofl'the'shaft 94 through arodIS? pivoted at the opposite ends to the. carrier plate-sand v v The throw of the rods I52.is varied by adjustably mounting. the pivotal con-. nection between the rods and crank members on, the crank members, as shown at I53 in Figures 2 andv 3. The intermittent rotations of the shafts I-Gii are transmitted to the rollers I35 and I31 by a gear I5i fixed on the shafts I46 and meshing with the gears M 3. The feeding of either of the webs II I is stopped should there be no closure cap in a pocket 65 to be positioned in alinement below either of the dies II2 by the next intermittent movement of the rotatable support 56. This is accomplished by means to position either of the pawls I48 out of engagement with theteeth of its assgciated} ratchet wheel I45. Said means comprises a lever pivoted on the bracket arm I41 and having a sinuous portion ISEiadapted to engage a pin lfofi fixed in. and projecting. from the pawl [48. The sin ubus. portion i 5,5,i's, normally actuated by a spring Itili. attached. to one end portiondSJ. of said levers the table'l to. position the pawl I43 out. of engagement with the teeth of theratchet Wheel I45, The. end portion I57 of one of the pawl engaging levers is extended in. a vertical direction, as shown, at 58 in Figure 3, and then laterallyv over and in spaced relation to the con: veyer 2Iv to permit unobstructed travel of, the closure caps from the hopper It to theabutment plate. 52. The sinuous portion $55 is actuated outer engagement with thepin I56 by a closure cap C infsaid pocket 55, by a lever I53 pivpted on; the bracket [is and having one end por-. tion. arranged with a closure cap engaging finger I60. The opposite end of the lever I59 e'x-. tend over an end portion IEI of the pawl engaginglever opposite the end portion I5], wlrierle-v by the lifting of the finger I60, by acIosure. cap lowersthe end portion I6! and moves. the sinuous. portion I55 out of engagement with the pawl I5 5, as shown in Figure 4.

Thewebs. I I I are supplied from rollssupported on. a pair of reels I62 rotatably mounted'on a shaft I53 supported from the table 1 byabracket [Be as shown in Figures 1 and 3. The websare guided and supported from the reels I62 to the web guides II3 by pairs of rails. I65 supported by the bracket arms I39. The waste portions of the webs from which the. linings. have been punched are supported and guided by plates I66, having the longitudinal edges flanged upwardly and supported by the brackets H4, as shown in Figure 4. The waste portions of the webs. are deposited in a suitable depository, not shown.

The closure caps being conveyed from thedie and punch mechanisms by the rotatable support 56 and having linings assembled therein by the punches II5 and ejector rods. I24 are removed from the rotatable support in the following manner. The assembled closure caps whichorigie nally were delivered to the rotatable supportby the conveyor 2| are removed from therotatable support onto the portion of the upper stretchof the conveyor 22 extending from plate 54 to. the drum 33 by a guide plate I61 supportedbythe platform and extended between the rotatable support bfi and segments 63 to disengage the assembled closure caps from the pockets 85.; and guide the disengaged closure caps onto a plate I68 supported by the platform 85. Thesucceed ing disengaged closure caps will move the pre: ceding disengaged closure caps onto the plate I68 and the upper stretch of the conveyor 22. A- pair of plates I63 are removably mounted. on posts fixed in the table I and engaged in a slot in each of said plates I69 and the plates'clamped to said posts by a wing nut, as shown at H0 in Figure l. The plates I69 extend over the rotatable support 56 and segments 63 to guide the closure caps from the conveyers 2i and '22 and retain the closure caps on the rotatable support and in the pockets 65. A portion of the plate 54 and adjacentplate I69 have an edge I'II extending insuperposed relation to the plates I61 and I68 to guide the disengaged closure caps onto the conveyor 22. The assembled closure caps on the conveyer ZZare transported to a suitable depository, not shown, at the drum 32 and are guide ed along said conveyer by rails I12 supported by the table I andarmsSB.

The assembled closure caps which were delivered to therotatable support 55 by the conveyor 22are removed from the rotatable support by a g" 7 plate I13 supported by the platform 85 supporting the conveyer 2| and extended between the rotatable support '3 and the segments 63 to disengage said assembled closure caps from the pockets 65 and direct the disengaged closure caps onto a chute I14 having an inlet end adjacent to the periphery of the rotatable support 56 and supported by the table 1, as at I15 in Figure 5, to extend through an opening I16 in the table 1. The lower end of the chute constitutes the outlet thereof and from which end the assembled closure caps are discharged onto the upper stretch of an endless belt conveyer I11 supported between drums I18, I19, drum I18 being rotatably supported in bearings at the ends of arms I88 slidably supported at the opposite end portions in brackets I8I fixed to the end of the table 1 on which the arms 36 are supported. The slidable mounting of the arms I88 permits adjustment of sa d arms to vary the length of the conveyer I11 and said arms are retained in adjusted position by bolts screw threaded in the arms and engaged in slots in the brackets with washers engaged on the bolts between the heads thereof and the brackets, as shown at I82 in Figures 1 and 2. To provide simultaneously adjustment of the drums 33 and I18, the inner arms 36 and I80 are connected to each other by a bar I98 fixed at the opposite ends to said arms, as shown in Figure l. The drum. I19 is rotatable in a bracket I83 mounted on the bottom of the table 1. The conveyer I11 is continuously actuated from the drive shaft I I through the shaft by a sprocket chain I84 engaged around a sprocket wheel I85 fixed on the end of the shaft 35 and a sprocket wheel I86 fixed on the shaft of drum I18 on which s aft said drum is fixed. The end of the shaft 35 which carries the sprocket wheel I85 is rotatable in a vertical arm I81 fixed to the inner arm I 80, as shown in Figure 2. Slack is taken up in the conveyer I11 by a lever I88 pivotally su ported by the bottom of the table I and rol ers I89 carried by the opposite end portions of the lever with one roller extending transversely below the lower stretch of the conveyer and the other roller extending transversely above said lower stretch, as shown in Figure 2. The rollers I89 are actuated toward and away from the lower stretch of the conveyer I11 by a shaft I90 screw threadedly mounted in the table I and having one end operatively connected tothe end of the lever carrying the roller positioned below the lower stretch of the conveyer I11 and the opposite end of said shaft extending from the top of the table 1 and arranged with a manipulating wheel I9I. As shown in Figure 2, the conveyer I11 travels in an inclined plane from the drum I19 to the drum I18. The closure caps are retained on the up er stretch of the conveyer I11 by guide rails I92 supported from the table 1. The conveyer I11 delivers the assembled closure caps to the same depository to which the assembled closure caps are delivered by the conveyer 22. v The closure caps are retained on the rotatable support 58 and in the recesses 65 by a pair of arouate rails I93 supported by the top of the table 1 to extend over diametrically opposite portions of the rotatable support and in spaced relation to the open sides of the recesses. The opposed ends of the rails I 93 are spaced from each other to permit the delivery of closure caps from the conveyors 2! and 22 to the rotatable support 58 and assembled caps from the rotatable sup ort to the conveyors 22 and I11, as shown'in Figure 1.
