6 Claims.

This invention relates to a structurally and functionally improved applying or assembling machine.

In its more specific aspects the present invention aims to provide a machine of this character which will be of particular value in the assembling of tops for receptacles and especially tops involving a disk or head portion to which a sealing plug is secured. Ordinarily the disk or head portion may be formed of wood, molded phenol resin, or other suitable materials, and the plug may be formed of cork. While this is a preferred unit to be produced by the present machine, it is to be understood that with or without suitable modification the present apparatus might readily be employed to advantage for the production of units formed of different materials. I

Thus, it is an object of the invention to provide an apparatus of this type and by means of which the plugs will be treated so that they may be properly applied and coupled to cap or disk portions.

A further and more specific object of the invention is that of combining in the same machine improved mechanism whereby plugs will be drilled and coated with, for example, an adhesive substance.

Another object is that of furnishing an assembling machine in which the plugs will be properly applied to the cap or disk portions of the tops and so that there will be little if any likelihood of these parts subsequently separating from each other.

Still another object is that of constructing a vention, and in which:

Fig. 1 is a top plan view of a forming and applying machine;

Fig. 2 is a side view thereof;

Fig. 3 is a transverse sectional view taken along the lines 3--3 and in the direction of the arrows of Fi 1;

Figs. 4 and 5 are enlarged fragmentary sectional views taken along the line 4-4 and 5--5 and in the direction of the arrows of Fig. 1;

Fig. 6 is a transverse sectional view of the glue applying unit, and

Fig. 7 is a sectional view taken along the line 1-4 and in the direction of the arrows of Fig. 6.

In these views the numeral II] indicates the deck of the machine and upon which turntables II and I2 are rotatably mounted. The former is, as shown, arranged below the horizontal plane of the latter and the peripheral zones of these turntables overlap.

Turntable II is formed with a series of openings I3 which receive plugs I4. Turntable I2 is also formed with a series of openings I5, each receiving top or disk elements Iii. While the plugs and tops may, as aiore brought out, be formed of any desirable and suitable material, they are preferably constructed of cork and phenolic resin, respectively. The plugs and tops may be distributed one within each of openings I3 and I5, or they may be placed therein by any suitable type of mechanism (not shown). Suffice it to say, however, that as viewed in Fig. 1, plugs I4 may be placed one within each of the openings I3 of turntable II, from, for example, the position adjacent the uppermost edge of the turntable through a zone of ninety degrees in a clockwise direction. Conversely, tops may be distributed within openings I5 from, for example, a position slightly to the left of the upper edge of turntable I2, throughout a zone of substantially one hundred and eighty degrees in a counterclockwise direction. Also, the openings of turntable II may extend above a supporting strip I'I, especially as shown in Fig. 2, and which will prevent the plugs from passing through these openings.

Associated with turntable II is a drilling machine or unit which has been. best shown in Figs. 1 and 2. This unit may conveniently include a motor I8 driving a pulley I9, which, by means of a belt 20, serves to drive a spindle 2|. The latter has affixed to it a drill 22 disposed in a plane such that it may be projected through any one of the openings I3 as the latter move below it. Also, a tube 23 may be provided at this point and be connected to a suitable source of suction to constantly remove material which has been severed from the bodies of the plugs. It is in- -tendedaccording to the present inventionthat these plugs be drilled throughout only a portion of their length so that one end of the same is uninterrupted while the second end of the same presents the mouth of the bore formed by the drill 22. Obviously, however, the extent to which drilling is resorted may accord entirely to the desires of the operator and the purpose for which the sealing elements or units are to be subsequently employed.

Thus, as the turntable is moved intermit-- tently and in a manner hereinafter described, the drill may be lowered upon the turntable coming to rest; this resulting in bores being formed in the plugs. Any plug material thus removed will not clog the machine because of the suction nozzle 23.

The lowering and raising of drill 22 is efiected by a rod 2:1 connected through a pin 25 to a beam 26; such connection conveniently being established by forming the rod with a slot within which such beam rides. The depth to which the bore is to be cut may be regulated by a member 21, affixed to rod 24! and suitably connected to the spindle so that upon the member being reciprocated the drill will be correspondingly moved. If a deeper or shallower bore is to be formed this may obviously be accomplished by simply adjusting member 2! to any desired position along rod 24.

Also, in order to retain plugs l4 against displacement and during the drilling operation, the rod 24 may slidably mount a bracket 28 formed with an. opening of adequate area to accommodate the drill, but of insuflicient area to permit of the passage of the plugs. This bracket normally tends to move downwardly, into contact with the upper plug faces, under the urging of a spring 29 which has its opposite ends respectively coupled to the bracket and the beam 25. To periodically elevate the bracket, rod 24 may adjustably mount a. collar 3%] which, as the rod moves upwardly, engages the bracket and elevates the latter.

Thus, assuming that the movements of beam 26 are properly timed, it will be apparent that turntable H will shift to move one of the plugs M to a position below bracket 28. Thereupon, rod 24 will be depressed, the bracket will engage the upper face of the plug and continued.- movement on the part of rod 24 will cause the drill to be projected with respect to the bracket and to thus form a bore within the plug. The depth of this bore will correspond to the position to which member 2! has been caused to assume along rod 24. Thereupon arm 26 will move rod 24 upwardly. This will cause a withdrawal of the drill 22 and any chips will be removed by the suction nozzle 23 or its equivalent. Stop will contact bracket 28 so that as the drill clears the bore (or subsequently thereto), the bracket will be elevated to assume its initial position. Thereupon, turntable II will move forward one step, resulting in the presentation of the next succeeding plug to the drilling station and the shifting of the drilled plug towards the gluing station.

Referring to the latter station, there is presented a glue bath or receptacle 3| conveniently provided with a holder 32 to receive a glue reservoir. An applicator is provided by conveniently employing a plug 33 of sponge rubber or equivalent material, and having the upper end of this material confined within a clamping ring or collar 34. The latter is screw threaded or otherwise affixed to a shaft 35. It is consequently obvious that by utilizing a cylindrical section of rubber stock, this may be clamped between the ring and rod 35, so that the end of the applicator is at all times in the form of a plane surface,

, sition incident to the action of spring til.

proper for contact with the end of a plug to be coated. Also, if it becomes necessary to renew this element, this may readily be done, it being moreover understood that, for example, by a nut 3%, or otherwise, the rod 35 may be extended or retracted along rod 3'! so that the parts may be properly adjusted.

Rod 31 extends slidably within guides 38, forming a part of a plate 39. This plate is slidably supported between rail portions 5}. Rotatably mounted upon a wall il which supports rail portions 49 is a gear A2. The latter, by means of a crank pin 43 and slot 23', is. coupled to plate 39, it being thus obvious that as gear 42 rotates the plate will be reciprocated between rails ll).

The teeth of gear d2 also mesh with the teeth of gears 4 rotatably supported by wall ii. Each of these gears is coupled to cranks d5the movements of these cranks being synchronized. Supported by the cranks is a link it disposed in line with the end of rod 37. The relationship of the several gears is such that to each revolution of gear 42, gears 44 will be rotated twice. Accordingly if the parts are properly timed, it follows that when plate 39 is in its innermost position, the applicator will be projected to be immersed within the fluid in bath 3i. While the applicator is projected incident to the periodic contact which occurs between link to and the end of rod 31, it is obvious that the applicator and rod will normally be maintained in retracted po- This spring has its lower end bearing against the lower guide 3d while its upper end bears against a collar 31 affiXed to rod 3?. Likewise, with plate 39 projected to its outer position, the applicator will again be lowered. Due to the fact that in the latter condition of the parts the applicator is in line with one of the plugs it, it follows that the upper surface of the latter will be coated with glue or its equivalent.

As afore brought out, turntable l2 overlaps turntable H. Adjacent such point of overlapping, a stop plate 4'! may overlie both turntables and strip 11 may be formed with an opening 48. In line with opening 33 there is provided a pin or head 49 secured to rotatable shaft 5b. The latter has attached to it a convenient form of driving means such as a pulley 5|. Moreover, shaft 50 is supported upon a lever which may conveniently be L-shaped and present arms 52 and 53 respectively. Adjacent the point of juncture of these arms a rod 54 may be coupled. Thus, as rod 54 is projected, the pin or head) 49 will move upwardly through opening 58 thus ejecting plug M from the opening E3 of turntable I I, and moving the same upwardly to a point at which the stem 55 of the top or disk l6 may enter the bore of plug M. This movement is continued until the upper edge of the plug is in firm contact with the inner face of the top l5. Consequently, the plug will be attached to the top and a complete article will be furnished, it being borne in mind that strip M will prevent any upward displacement of the element l5 during this operation. Moreover the film of adhesive or equivalent material will be evenly and properly disposed over all surfaces which are to adhere to each other, due to the fact that incident to the rotation of shaft 58 the plug will not alone move into contact with the surfaces of the top, but will also be turned with reference to such surfaces. This turning will not occur to an ex? tent such that a detrimental effect would result. In other words, while shaft Ell is turning and causes rotation of plug 14 as the latter is elevated by rod 54, only a relatively minute degree of rotation will occur on the part of the plug with respect to the top and while the parts are firmly applied to each other. Immediately thereafter pin or head 49 will begin to retract so that its continued rotation will have no further effect on the plug which is now firmly fixed with respect to the top.

It will thus be seen that the plugs are transferred from turntable II to turntable I2 with which they now travel :to :a point adjacent delivery chute 56. Before departing from a consideration of this phase of operation, it is to be noted that as shown, especially in Fig. 4, the openings I3 of turntable II are tapered inwardly or downwardly while the openings I5 of turntable I2 are preferably tapered upwardly or outwardly. It has already been noted that strip I1 prevents plugs I4 from moving downwardly to too great an extent, such strip moreover supporting them throughout their entire path of travel. By conveniently having the openings I3 of tapered configuration a firm contact, is assured between the plugs and the edges of the openings to thus stabilize the former. Conversely, due to the tapering of openings I5, the end of the plug is guided and squeezed firmly as the latter is rammed upwardly by the pin or head 49. Not alone does this assure a proper contact between the stem 55 and the walls of the bore, but it moreover prevents any probability of dislodgement until a deliberate ejection of the article occurs adjacent the delivery chute. At this point the plugs are in line with arm 53 of the lever which carries an ejector element conveniently including a screw threaded stem 51 and a head 58 presenting angular surfaces the major one of which is inclined toward chute 56. Thus, with rod 54 projected, head 58 will be projected through one of the openings I5, thus ejecting and simultaneously diverting a complete closure element to delivery chute 55.

While various forms of drive may be employed in a machine of thischaracter, it is preferred, aside from rotation of drill 22, to utilize a single primary source of power. To this end there may be supported below the deck of the machine a rotatable shaft 59. The latter mounts cams 60.

Coupled to one of these is a crank rod 6| coua pled .to rod 54 to effect reciprocation of the latter. Coupled to the second cam is a crank arm 62 which may conveniently be secured to a rod 83 coupled to the end of lever 26. In this fashion thelever is rocked to elevate and depress rod 24 and the drill 22.

Also affixed to shaft 59 is a gear 84 which meshes with the teeth of a gear 55 to rotate a shaft 86. The latter mounts at Geneva drive including a roller and stud assembly 61. Positioned below turntable II is a Geneva plate assembly including, for example, a slotted plate 68 for co operation with the stud afore mentioned, and a steady plate 69 to coact with the roller of the assembly 61. Thus, an intermittent movement will be imparted to the shaft mounting turnt'able'l I. A gear II may also be secured .to this shaft and have its teeth intermesh with a gear I2 affixed to the shaft 13 which supports turntable I2. Thus, the movements of these turntables will be perfectly synchronized.

In order to effect proper operation of the glue applying mechanism, the shaft 59 additionally ported in brackets 11. At its upper end this shaft mounts a gear I8, the teeth of which mesh with the teeth of gear 19 to rotate a shaft 88. In turn, aflixed to the latter is a gear 8| the teeth of which mesh with the teeth of gear 82 the teeth of the latter, in turn, meshing with the teeth of gear 42 which will operate the parts in the manner heretofore described.

Finally, it will be observed that shaft I6 may also mount a pulley 83 which drives a belt 84 passing around pulley 5| to thus effect rotation of shaft 50. Of course, the several parts are all conveniently rendered capable of adjustment so that wear and varying conditions of operation may be compensated for.

As illustrated, turntables II and I2 will rotate once to each 20 revolutions of shaft 66. Also, shaft T9 may rotate, for example, 140 times to each revolutions of shaft 68, while the head 49 may rotate, for example, revolutions to each rotations of shaft I6. The foregoing furnishes one convenient form of drive ratio which has been found to be satisfactory. Obviously, this might be varied as desired.

Briefly reviewing the operation, it will be seen that with shaft 59 operating, the operator will distribute (automatically or otherwise) plugs I4 within openings I3 and tops I6 within openings I5. Thereupon, each of the plugs is drilled to the desired depth and is subsequently coated with adhesive. Such coating obviously occurs as the turntable indexes and comes to a position of rest. At such position, the parts are timed so that the applicator is projected outwardly or beyond the trough 3! and downwardly into contact with the upper face of the underlying plug. Prior to a further indexing of the turntable, the applicator will move upwardly under the action of spring 35'. immersing of the applicator occurs while the turntable is indexing or moving. Thus, an operator is assured that the applicator is properly coated with adhesive due to the fact that the latter is immersed within the trough in the intervals between which it coats successive plugs. After this has occurred, the plugs are twisted into contact with the tops. Of course, if the tops are of the type where-this action should not occur, then the drive to the pin or head 49 may be disconnected and this member may, if desired, be locked in place. Accordingly, if the stem 55 of the top be longitudinally ribbed, or corrugated, no detrimental twisting of the parts with respect to each other need, or will occur. These tops. have received no treatment up to this point, and while in association with turntable I2. Thereupon, they are ejected and distributed through chute 56 or otherwise.

Thus, among others, the several objects of the invention as afore noted are achieved. It is obvious that numerous changes in construction and rearrangement of the parts might be resorted to without departing from the spirit of the invention as defined by the claims.
