AUTOMATIC BOXi-BODY AND COVER ASSEIVIBLING APPARATUS.

iippiicaiimiY inca January e, 1923. semi No; 610,960.

My invention relates generally to apparatus for automatically assembling sheet vmet-al box bodies and covers, the particular adaptation herein shown and described being for the purpose of assembling boxes of the type commonly used. for the packaging of aspirin. a

A principal object of the invention is the provision of an assembling apparatus of `the character stated, which operates with a full automatic action to advance the box bodies and covers and perform successive asse1nbling operations thereon at a high rate of speed and efficiency and without-necessitating particular attention of theattendant.

A further'object ofthe invention is the provision, in apparatus of this character, of devices for automatically preventing congestion of either box bodies or covers in the passageways through which they are fed to and past the assembling mechanism.

VA still further object of my invention is the provision of mechanism for preventing the feeding, either of bodies or covers, to the assembly station inthe absence of a companion part for assembly therewith.

Other objects and advantages of the invention will be apparent as it isV better understood from the following description, which, taken in connection with the accom panying drawing, illustrates a preferred embodiinent thereof.

Fig. 2O is adetailed section taken substantially-aiong thea'xis of the body feedcontrol shaft showing the construction thereof.

Attention is rst called to Figs. 13 to 19,

inclusive, illustrating a box adaptedV to be assembled by the apparatus of my invention,

the sectional views showing the positions and relationship at the various stations in the machine. Y

The box body 21v may, of course,v be of any desired shape, 0r size, and in the present instance is formed with recesses 22 and a hinge forn'iing lug 23'inthe rear wall thereof. The recesses 22 are formed by outwardly extendperspective view of anfasico ingebead sections and the lug` 23 is beaded. Y

inwardly so that when brought to final position, a hinge bearing is provided.V The box cover '24 has a coi-operating hinge forming lug in the rear flange thereof, said Vflange being' cut away so that the ends of said lug project beyond the body thereof, these ends ,being adapted to be disposed in the recesses 22 when the parts Aare assembled. The varif ous operations ofthe machine will be under-y sitioned, if desired, in convenient relation-V ship to a press, or other machine performing a preceding operation upon the metal. he box bodies and covers are fed, in any suitable manner as by a conveyer, from such preceding machine into guideways28. and 29 (Figs.

3, 4 and 5), the former'of these being vertically arranged and adapted to. have the bodies fed in upright position therethrough-and `the latter being horizontally arranged, so

da, connecting rod (Fig.

in .closed position.

that the covers may remain in horizontal positionv throughout their course of travel. These passageways are :in adjacent relation ship, being arranged respectively alongV the Vapproximate lines 3-3 and 1*4, as shown in Fig. 1. As av means of directing the bodies and coifers along their passageways, I vemploy compressed air, which is delivered from a supply pipe 31 through branches 32 to` a chamber 33, from which openings. 34 lead into said'passageways.'

. A safety defyice isprovided for preventing the overcrowding of either the bodies or covers inthe channelsfthrough which they are fed, this mechanism beingV illustrated in de-V tail in Figs. 3 and 4. Referring first to Fig. 3, it will be noted that a trap door 35 is provided .at the bottom of the channel 28, this door being hinged at ,36 and normally held in closedV position by means of a spring 87 connected at one end to an arm 3 8 extending from the pivot of saiddoor, and at the. opposite end to a stationary part of the frame.-

A slide 39 .is mounted in a way 41 which is provided in an. upstandingbracket 42, and this slide is constantly reciprocated by means of a link 43, a bellfcrank lever-44 and The, bellcrank 44 is pivoted at 46 to ears 47. upstaudingrfrom the table 27, and the rod is reciprocated by certain,continuously operating mechanism to be hereinafter described. Upon the slide 39, there Ais piyotally secured a lever 48 and dependingfrom thislever,` at one end, is a rod 49` connected at its lower end vwith the trap door .At theopposite end of said lever 48, a detector rod, or pin, 51 is secured in a 4slot 52 and'extends through a bearing` and an aperture 54. into the channel. 28. During the constant reciproca tion of the slide 39, said pin 51Y is permitted to enter the channel 28, if nobody bein positionto obstructit, andthe door is held In the, event, however, that` the bodieshave backed up in the channelv 28 so that one is present beneath the aperture( 54y upon the downward stroke of the pin 51, the rod 49 is forced downwardly andthe trap door` 35 opened to permit the discharge of bodies positionedthereon. Said door, 35 is connected `by means of a linlxF 55 witha guard wing 56, which is pivoted at 57 to the frame and which obstructs the channel 28 when the door is opened.

Extending from the slide 39 above the lever 48 is a pin 58, which carries at its outer end a lever 59v which serves to operate a detector. pin G1, corresponding to the pin 51, and is connected by a rod 62 with a` trap door (53v (Fig. 4) at the .bottom of theapassagei29, being secured thereto by a. screw (i4. This mechanism. operates in a. manner similar to that shown in Fig. 3 and further description is, therefore, believed to `be unnccesiriry.

rEhe bodies and-covers' are directedtnrough the channels 28 and 29, which are illustrated insection` in Eig. 5, until the. covers arrive beneath anA opening 65, as shown.Y inV Fig. 1.

This opening, of course, permits escape of the. air which is employed as a feeding inedium andthe coyersstop-until moved further by instrumentalities tobe later described. 'lf he bodyr channel is cut awa); aft-6GA opposite to the` opening 65,. so'thatv a. body. and a cover are delivered to stationary positions in alignment .substantially on the line 6 6. in

A can body conveying.` arm 67 ismounted on: a squarecontrol shaft (38 (Fig. 29). which is mounted in bearings. 69. and 71 (Fig. 1), said arm beinginovable lengthwise, of said shaft through the instrumentality of a. slide 72 and an arm 73. Said slide 72 is reciprocated by` meansA of an arm 74, connected therewith by means ofa link 79, and cai* ried on av short shaftf75 havingibearings 7 6 onS the table 27, said shaft being rotated by anarm 77 (Fig. 5) on a short shaft 7 Rcarryingrat its lower enda roller adapted to ride inav grooye 79l of an operating cam 8l car-l rie-d on a main drive shaft 82, these parts being particularly illustrated in Figs. 2 and 54 of the drawings.

A finger 83 is securcdto the conveyor arni 57V and is norn'ially. disposed in the channel 29 in the pathof the boxv covers, as illustrated in Figs. 5 and 6. The shaft G8 is givenintermittent rocking motion by means of an arm 84. a` link. 85 and a bell-crank lover 86. the, latter being mounted on an auxiliary shaft 87 and carrying a cani roller 88 acted uponby Va cam 89 on the main drive shaft 82. The upper arm ofthe bell-crank 86 is connected by means of a spring- S0 with a depending flange 80 of the table 27. which tends to hold the conveyer arm G7 vin opera tive position.j Rotation of the shaft (SS in counter-clockwise direction li tsk the linger 83 and, while in its lifted position. it is moved rearwardly with the arm 67 and when again lowered, it engages within a cover which is moved forwardly upon the next movement of said arm toward the right, viewing Fig. 1.

titl

After the cover has been advanced to the station shown in Fig. 12, it is movedt-ransversely toward the body channel byV means of a slide indicated by the reference charac ter 91, said slidebeing reeiprocated by a bellcrank lever 92 connected by a link 93 with a depending arm 94: secured. to said slide by means of a screw 95. A cam roller 90 is carried in one arm of the bellecrank 02 and rides in a cam groove 07 in an operating cam 08 carried en the shaft I shallnow'describe the mechanism where b v feedingof a body to the assembling station is prevented in the absence of a cover in position to be attached thereto. Upon moveH nient of the slide 91. toward the left, viewing Fig. 12, the cover is brought beneath a retaining plate 99 and'above a. detector pin 101. Said detector pin normally engages the Slide 99 and is rounded at the iop to permit of the depression thereof by a cover in pass` ing thereover and at its lowerend. rests upon an arm 102 carried upon a shaft 103 having bearings in brackets 101 depending from the table 27. The plate 09 is vcarried on an arm 105, which is mounted on a shaft 100, the latter being given a slight rocking motion by means of anV arm 107, a link 103 and a bell-crank lever 109 mounted on the shaft 87 and carrying a: roller 111 riding 'in the groove of an operating cam 112 upon the shaft 82, these parts being shown most clearin Fig. 6.' Y 1f a cover ispositioned over the pin 101, the shaft 103 is rotated by the arm 102 and a second arm 113 on said'shaft 1,03 is forced downwardly against the action of a spring 114 secured to said. arm and to the bottom of the table 27. Said arm 113 is clearly shown in Fig. 5 in the position assumed when a-Vcover is not present above the pin `101 and it will be manifest that, with the arm 113 in its upper position, a pin on the knuckle 1.15, forming the connection between the arm 84: and the'link 85, Vis cngaged by a hook 116 on the arm 113 when said knnck e is forced into the sphere of action of said. lever by the bellecrank 86. It will thus be impossible for the shaft `(i310 be further rotated and the box body conveyor arm 67 is held in its outer, or inoperative position if a cover is present or in position over the pin 101, the shaft (i8 maybe freely rocked by means of the arm 311-, the arm 113 beingr held in position out of the path of the pin y 115 against the action of the spring 114 by the pin 101 permitting normal operation of the body feed.

I also provide a device for preventing the feeding of the covers in the absence of'a body at the assembling position, this device being illustrated in detail in Fig. 3. As the bodies reach the open section of the channel 28, and approximately at the` point indicated by the line 6-6 in Fig. 1, they are engaged by a rear finger *117 on the conveyor by the casting 118 latch 1231is pivotally secured at 1211` inthis recess.,v Said latch is normally forced out` wardly by ar pin 125,\which is under the tension of a spring 126. The latch `123 is provided centrally with a beveled surface127, upon which a body 21 is adapted to actin its forward movement under the influence of the linger 117 on the arm 67. lf a body be present at this point, the latch is forced inwardly and the body advanced tothe position indicated at 128 in Fig. 3. lhen the arm o? is again moved to the .left upon the shaft `68, a forward finger 120 on said arm engages the body vat the station 128 and the rear finger 11i7 engages a second cover which has been delivered by the air feed.V The forward cover, at this time, is positioned in aV recess 131 in the latch 123. Upon the next forward movement of the conveyer arm, the forward body is advanced to the right to the next operating` station. In the event that a body 21 isV not present to act upon the beveled surface 127` of the latch 123, the finger 117 on the arm 67 is forced ontwardlj, since the force of the spring 12S acting upon said latch is sinheient to overcome the weight ofsaid arm 67. 1n this manner, the body conveying arm is moved to inoperative position, which results in lifting the finger 83 by which the covers are advanced with con# sequent failure to advance a cover to the assembling station. The forward body, meantime, vill remain in the recess 1.31 of the latch. From the foregoing,it will be seen that neither a body nor a cover-can be advanced tovsaid assembling station in the absence of a Companion part to be `assembled tlierewith.V i Y l Assnining that a. box body and cover are positioned in adjacent relationship atthe assembling station, the next'joperation is the bending ofthe hinge lug 23 from the position illustrated in. Fig. 17 of ltie drawing to that illust-rated in Fig. V13.v The mecha-` nism for performing this operation is per haps bestillustrated in Figs. (i. 7 and 12. A sliding block 132 is carried iipon the arm 105 and a forward finger is pivotallyl connected at 134 to said sliding block 132.`

The linger 133 is normally held in lifted position by means of a spring-pressed pin v135 projecting from the block 132 and bearing against a lower extension 136 at the rear 0f the linger 1.33. Said slidingblock 132 is given a reciprocating movement imparted from the slide 91 through mechanism illustrated in detail in Fig. 7. Said mechanism comprises a reciprocating arm 137, which is rotatably mounted in abraclret 138 and is provided with a lower projection 139 which is acted upon by theslide 91, and with an upper projection 141 which acts upon the sliding-bloeit132tomove the same in unison with the slide 91, said arm'141 being also adapted to move the slide 132 rearwardly by means of a hook 140 extending beyond said arm .at the rear oifvthe slide. Upon movement of theblock 132toward the left, viewing Fig. 12, lower projection 136 on the finger 133 acts upon a pin 142 provided in an upward projection 143.011 the retaining plater 95), forcing the forward end ot said finger downwardly and against the inner lug 23 on the box body. The forward end o't said linger 133` ic grooved, as indicatedat 144, and vthus adapted to accurately engage the Vlug 23 and bend the sain-e to desired position, Upon the receding movement ot the block 132, the finger 133 is lifted bythe action ot the pin-135. At this point,'it may be noted that the arm 105, carrying the slidingbloclr 132 and the retaining plate 99, is providedwith a4 rear extension 145, which is normally pressed upwardly by a spring 146, the upward movement being limited by a set screwf 147. In this manner, all lost motion is prevented andV the desired limited rocking motion is imparted to the shaft 10.6.

Y After the lug 23is bent downwardly over thercorresponding lug on the cover and the hinge thus partially formed, the box is advanced onestep toward the right by the action of thev succeeding boxes thereon. The 4next operationis the opening of the box, accomplished by turning thebody 21 to the horizontal position, shown in Fig. 18, this being done by mechanism illustrated particularly in Fig. 9. n An arm 148'is pivoted at 149 to a vfixed member 151 on the vframe and is connected by a` curved link 152 4with a bell-crank 153 carried on the shaft 87 and operated by a cam 154, on the main drive shaft 82. The arm 148 is providedrwitha hinged extension 155, which is adapted to engage. overthe box 21 when in the forward position and to move the, same downwardly about its hinge .as a pivotal axis to horizontal position. It will `be noted that the cover 24. at this point, is held beneath a ,retaining guide 156. and the body, after being brought to horizontal position and again moved in forward direction, passes under a similar guide 157.

AThe action of the advancing boxes then brings the partially assembled body and cover to the final clinching` station, which is illustrated in Figs. 10 and 11. A sliding toggle mechanism is employed for this purpose and consists oi' a piston 158 extending through a bearing 150 and having at its front end a bifurcated portion'159 carrying a` pivoted member 161 11), which has a lower extension162. provided with a lclosing finger 163, andan upper extension 164 to which'is pivotally secured a second closing iinger 165. Said linger 165 isalso centrally pivotcd at 166 on a frame bracket 167 and is forced over center and caused to c0- operate with the linger' 163 upon forward movement oi'. the piston 158. "his: results in the .tinal clinching` otl the lugs 23 and 22 into the relationship shown in'Fig.19, thus completing the hinge.

The piston 158 is reciprocated to open and close the Clint-hing jaws by means o't' a cam 168, which operates an arm 169 connected by links 171 and 172 with said piston 158.

Alfter the assembly ot the bodies and covers is completed at this station, thefboxes are again moved toward the right in a channel 170 and ejected from the machine.

The main drive shaft 82 isvdri-ven by means of tight and loose pulleys-173and 17 4, the belt being shi'ttedvfrointhe one pulley to the other by means of a. belt shifter 179. Said shaft 82 has bearingsin brackets 175 and 176 depending from the table 27. rilhe shaft 87 is ,similarly supported from said table 27 by means ot brackets 177 yand 178.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made lin. the form, constructionv and arrangement ot the parts, without departing from the spiritand scope ofthe invention, or sacrificing all of its materialV advantages, the form hereinbetore described being merely a preferred embodimentthereof.
