Wang e jaja @y flexible material thereto for reinforcing andl Patented Mar. 3, 1931 UNITED STATES GNTHER MEYER-JAGENBEBG, 0F DUSSELDORF, GERMANY BOX-MAKING MACHINE Application led April 8, 1927, 'Serial No. 181,929, and in Germanyl July 30, 1926. l

This invention has reference to im rovements in the manufacture of boxes of su stantially flexible material and it relates in particular to means of applying pasting pieces of other purposes and for applying printed or stamped matter to the box sections or for directly printing and stamping the same or for submitting them to the treatment by means of dies and the like. The box sections in these i turn to its initial position which results inv operations are preferably treated in the WellknoWn manner by circularly arranged printing and stamping instrumentalities mounted on a turntable, the said instrumentalities, dies, pressing and printing means, stamps and the like being operated and controlled in accordance with this invention from a cam roller which is so arranged and constructed that it will participate in the-partial movements of the turntable or the like carrying the printing or pressing means, While after each individual partial rotation the cam roller will rethe lowering of the printing lor pressing means, plunger or the like at the feeding stav tion of the box sections and the simultaneous raising of the plunger or the like on the stationsoperating as ejecting means, While the pressing and printing instrumentalities which happen to be in the printing or stamping position will not be operated. It is another object of this invention to provide a safety appliance inconnection with the other instrumentalities, by means of which the admission of a piece or slip of coating paper which acquires adhesiveness by heat to the charging station of the box sections is prevented, in case of deficient feeding of a box section from any reason, so as to obvia-te the possibility of a piece of coating paper or the like being forced into an empty matrix and adhering to the pressing die or the like.

The invention will be further described by reference to the accompanying drawing showing by way of exemplification a preferred embodiment of the principles thereof,

Upon the base plate 1 and by means of posts 2 a'rotary carrier is mounted comprising a table plate 3 which carries the supports 4 with rollers 5. Upon these rollers the outer marginal portion of a turntable 6 is adapted to rest which is secured to a vertical shaft 7 which is supported on the base plate 1. Above the turntable 6 a cross-shaped skeleton bearing member 9 is arranged the apertures 10 of which lserve for the vertical guiding of the rods 11 of the pressing dies or plungers 12 the reciprocation of which in the ver"- tical direction is elfected by a cam cylinder 13 in the vcam groove 62 of which the free ends of the rods 11 are suspended by means of rollers 14. The cam 13 is retained in position on its top portion by the guide rollers 70. Below the pressingv lungers or dies 12 matrices 15 are arranged? each matrix having a supporting stem 15a slidably engaging the bore of a bracket member 15b and yieldingly supported therein by a backing spring 15e. vThe heating of .the matrices may be effected by gas burners or thelike 16. The lturntable 6 is operated bypmeans ofa train of gearing 66 and by the transmission gear'- ing 17 from a Geneva movement 18 which is driven by a roller 19 (Fig. 2) secured to 21 on the shaft 22 which transmits its movement by means of bevel gear wheels or initre wheels 58 to a shaft 59 (Fig. 4). On shaft 22 is a gear 22 receiving inotioii from a pinion 22b on a drive shaft 22c carrying pulleys 2,2d oi: other means for rcceiying motion from any suitable source of power. A dog or lock bar 24 which is operated by a'cani' surface of apdouble. cam disc 23V,mounted'v upon the shaft 59 (Figs. 4 and 5) serves for the arresting of the shaft 7 and of. the turn table 6, after the feeding of the Geneva wheel 18. On the shaft 22 a cani disc 25 is disposed which, by means of a lever 26. and the vertically disposed transmission shaft 2i carryingsaidlevelr operates and controls a Ptoothed'segnienth28 (Figure 2) which trans- I nitsv its oscillatingmovement to a curved rack orgear wheel 2901i the cani 13 and' in consequence' thereof this Cain is compelled vto perform an oscillatory movement likewise.

tha't is to say, first the movementI in the saine direction as the.` turn-table 6, and upon the reversal of the Ymovement'of the segni'entfi'n 'the direction opposite to that of the turntable. .A conveyor 30 transfers the box sections31 to a platform 32 (Figures 1 and 2) froin'wliich they are carried across the vmatrices y15 substantially at right angle to the direction of movement of the apron' or `.conveyor 30 and during this movement they are supported ybynarrow and spring sup- 37, a bar 38, anda spring 38. and to -which downward movement is imparted through a cam roller 39 from a cani disc 40 on the shaft 5S). The suction device delivers the paper wrapper 31 between thetongs or grippers 41, 71. Tongs 41 are mounted on non-.circular rods 72 which are rotatably and slidably itted in bear- ing eyes 73, 74. Onathe rods 72, between the veyes 74, are mounted crank arms 75 connectedby rods 76 with springpresscd bell-crank levers 77 carrying rollers 78 which respectively bear against a cam surface of the double ani disk 23. heretofore referred to, and against the cani surface of another cain disk 23', ou ,the rotationL which thctongs 41 are raised and lowered (opened and closed with respect to tongs 71) at proper intervals. The tongs 7l bars 42 which arc..,i no\ jable to and fro by Atongs-41 areythen loweredvso as to claiiip the wrapper between them and the tongs 71 and the-ntheclosed tongs, carrying with them the wrapper, are moved by parts42, 42 toward-the -niatrix 15 which is in receiving` position until the wrapper lies Vabove and in exact registry with the matrix. At this moment tongs'41'are again lift-ed, thus releasing the wrapper 34 which drops vonto the finan-ix.'l Parts 42,'[42 then operate t'oreturn the tongs to initial position. The box section 31 arriving yby way of thecoiiveying apron upon'the platform 32 is pushed' below the pressing plunger or die 12-and ab'ovethe anvil or matrix `15 by .i` slide 44 `(Fig. 7) and by the action of a spring '4.6l acting uponthe two-armed lever 45. The lmovement vof 4the lever 45 is produced .byniean-sof a cani disc 47 upon the shaft 59, uponwhich cam discthe free'end of said two-armed lever 45 is adapted to bear. To theslide or push arm 44 a safety device "is connected which consists of a locking pin 48 (Figures 5 and 7) adapted to become engaged behind an adjustable liig 50 of a. feeler 50 keyed to the shaft49 and rotatable therewith so that the slide'willbe locked from movement un'tilftli'e.

pinis released'by the'feeler. Further. this Afee-ler 50 acts on a bar 52. .with which it is connected by lever 51, which latter is' held rigidly on the pivot pin 49 of the feeler. The other end of the bar 52 isinounted on the standard pillar 2 in the slot' or bifurcation of a horizontally bifiircated guide inem"- ber 53, viii tlic top and bottom walls of which are registering cut-outs 54; and on the bar 52 there is provided a'corresponding' cut-out. 54. Depending upon the position of the ffeeler 50the bar 52 is: either in the, yposition according to Figs. 7 and 7a or according to Figs.,8 and 8a. ln thefirst-named position the cut-out 54 is at one side o1 or out of registry with cutout 5-'1-.while in thi` other position the cutouts 54 register.'v ln Fig.

'7a one finger 38 of hai' 38, VHwhich latter 'moves the sucker 35. so contacts with thc -bar 52that the linger is held in itslo-werniost position. But if tl'ie bar (Fig. 8) is moved to bring cut- outs 54, 54 into registry. then finger 38 Acan pass through cut-out -54 of bar 52 iipwardly. lf. them-feelin' 5t) is moved through a box 3l in upward direction (Fig. 8) andthe cani disk 40 releases the rod 38, then the spring 38 will pull the rod 38 so far upwardly. that the linger 38"engages in the cut-out 54 and the sucker 35 Yis moved over toward the pile 34. If a box fails to arrive, `then the -feelcry likewise will remain inthe p'ositioiiFig.l 7, the cut-out '54 jb'eingout of registry with thecut-outs` 51 of guide If now the rod 38is'released` from' "thecani disk`40, then'it is prevented from ascending because linger 38"contacts with Ofll'fst e .s from pile 134. Another'slide o`1 push arm`55 `(Figure 2) parallel 'to the' slide Hand operbar'. 52, the sucker 35 rei'nains in its position and no cover paperis withdrawn ated by a syst-em of levers 67: serves for the 'ejectionl offthe finished box portions', The

saidarni carries fingers'or the vlike' 56 (Figi'iref2) on the 'arms 68, which `inthe operative position `aredisposed above lthe frame o f'the die or matrice 15 and push the box portion offjthe same upon the raising of the pressing die o rpliinger'l. Anangle .piece 5T (Figu'i'e'2) securedvto'oi'ie of said arms 67, leads the box to be vdelivered onto.`

`an inclined chute orpiece of sliee'tfn'ietal 69.

' The operation of the vdevice described is substantially'as follows: The prepared box sections 31 are conducted by theconveying apron-or the like 80 to theplatform 32 where theywill press against the feeler the lock v ing'lug 50 of which will become disengagedl and Will releasethe slidej'or push lbar 44.

` Bars 61 rockingly disposed onthe shaft 60 (Figures land 3.) are bearing at the saine time with their free ends upon the box `sections, so thatowing to sufficient' friction with the conveying apron'being produced thereby the. reliable feeding forward of the boxparts l and the release of the f eeler arrangement f will only take place, when: the box section 'l has assunieditsproper position with relation to the slide 44. This slide will then push lthel fbox section sideways at substantially right `angle tothe lp re'v'ious direction of movement ontothe dieormatrice 15 located at the j pressing station I wherethe boxsection rests upon'the spring acting guide barsi33. At the saine time la wrapping paper is pulled off the-pile by the suction member 3 5, inasmuch as by` the release of the slide4f1 the locking of the bar 38 has been discontinued, the said piece of lwrapper beingr placed across thel matrice 15 by thetongs 41. The plunger or pressing die 12 is lowered by means of the cani race of the cam 13 and forces the b ox section 31 upon the wrapping paper 34 Figure 10), while the supporting'bars 33 spiing actingly yield in the downward direction. By the use of the heated matrice 15 the pasting of the wrapping or enveloping paper 1s effected in the usual manner, the paste upon said wrapping paper becoming sticky by heat, and upon continuing the downward movement of the plunger 12 the box parts are pressed together and united (Fig. 11). Under the action of this compressing pressure the box part is moved through the other treating stations II, III, IV. On the last station the compressing pressure is released,

invention, as expr the plunger or pressing die is raised,'and the fingers 56 of the -pusher or slide 55 push the finished box part oi'fthepressing die 12,'and

the pusher eiect-s it into the chute 69.

The raised' portion of the cam race 62 (Figur'e 2) moves up and down between the stations I and movement o IVin viewof the reciprocating the compression and the ejection at these stations is produced. The camlSparticipates with the same' angular velocity in the partial rotations of the tiirnt'able 6, While 'after each partial rotation it is rotated back again into its initiall position bythe' segment28. In

this last stage of movementth'e `plunger or pressing dieA 12 is lowered at the charging stationI, and atl the ejecting station the pluiigcr issimultaneoi'isly" raised, kwhereupon by means of thethen following 'partial rotation of the tu'rIiLtable 6' together ywith-the roi'tation' of'fthe cam 13' 'this raised plunger is transferred to the stationI. At the stations II 'and I II the pressing'dies or plungers 12 remain int-heir lowered position. i -Instead of four stations a greater' number thereofniay obviously' be employed, so that the duration of thep'ressing'operation is extended. Other changesan'd modifications are also possible within the "scope andspiritof vmy invention, as directed bylocal conditions andthe convenience Lof the user, and without thereby deviating from the principles of the 1.
