- the block 52 also carries a pair of opposed pinch blades 53 that cyclically are caused to move inwardly against the cap skirts and pinch opposite sides thereof against the cartridge necks.
- the pinch blades 53 are mounted to pivoted levers 54 that are spring-loaded to open position.
- the upper ends of the levers carry rollers that ride the surface of an endWise-rnovable cone 55.

- the spinning heads 60 of which there are two, are spaced apart a distance equal to four conveyor-chuck spaces. Accordingly, the lead cartridge of the pair leaving the pinch station will skip the first spinning head at station #8 and the second cartridge of that pair will come to a stop in axial alignment with the spinning head at station #8. On the next index movement the aforesaid lead cartridge Will move and come to a stop under the second spinning head at station #8A.

- each head 60 is constructed to revolve around a central non-rotating spindle 64 that carries ⁇ at its lower end an adjustable cap-.seating head 65 contoured at its end to fit the top of the particular cap.
- the capseating head 65 applies downward pressure on the cap and keeps it from rotating and from being dragged around by the pressure of the spinning rollers 66.
- the spinning rollers preferably three in each head, are journaled at the lower ends of levers 67 pivotally mounted in each spinning head body.
- the upper ends of the levers 67 carry antifriction rollers that ride the surface of an axially shiftable cone 68.

Scribner, Westfield, NJ., assgnors to Cozzoli Machine Company, Plainfield, NJ., a corporation of New Jersey Filed May 20, 1963, Ser. No. 281,564 14 Claims. (Cl. 53-37) This invention concerns improvements in an apparatus for handling cartridges or other small cylindrical vials with the least possible manual contact. In its more specitic aspects the invention undertakes to provide apparatus having the capacity for magazine loading of cartridges in horizontal position, followed by orientation to vertical position and placed in spaced pockets of a conveyor. The conveyor causes the cartridges to move intermittently to and through purging and filling sta-tions after which the cartridges have caps successively loosely applied. After the placing of the caps, the cartridges are moved to an adjacent preliminary pinching station Where the caps are given a light pinch suiiicient to retain them in place while lbeing moved to a spin-sealing station. At the spin-sealing station the skirt of the cap is rolled in under the lip of the cartridge to produce the finished seal, upon cornpletio-n of which, the filled and sealed cartridges are successively discharged from the conveyor and again oriented to horizontal position for convenient inspection.
A further aim of the invention is to provide cartridge handling apparatus having one or more of the above characteristics with additional features of adjustability to process cartridges of different diameters and/or different height, adjustability as to quantity of fill, adjustability for accepting caps of different styles, and with automatic compensation for variations in the nominal dimensions of the cartridges in any given lot or run.
Still a further objective of the invention is to construct a machine that will mechanically orient and load, till, cap, and seal cartridges at production rates greater than has been possible heretofore, and to that end we propose an apparatus for loading cartridges two-a-t-a-time, centering the necks of the cartridges and detecting for blanks tWo-at-a-tirne, successively applying caps to the cartridges while in motion, securing the caps two-at-a-tirne, spinseal two-at-a-time followed by successive discharge in groups of two. p
Another purport of the invention is the provision of a` drive transmission constructed and arranged to afford continuous motion to certain components of the system, inter. mittent motion to other components of the sys-tem, disconnect means for certain components so that they may be stopped while other components continue their particular functions in the sequence, and with segregated controls for main machine operation, for the loading operation, for cap feed, and for the spin-seal operation.
Other objects and advantages will be in part indicated in the following description and in part rendered apparent therefrom in connection with the annexed drawings.
To enable others skilled in the art so fully to apprehend the underlying features hereof that they may embody the same in the various ways contemplated by this invention, drawings depicting a preferred typical construction have been annexed vas a part of this disclosure and, in such drawings, like characters of reference denote corresponding parts throughout all the views, of which:
FIGURE 1 is a ow sheet illustrating schematically the primary components of the organization, the sequence of the operation identitied by stations numbered l to l0, the drive transmissions and their respective controls.
FIG. 2 is a front elevation of a machine incorporating the invention and which includes the mechanisms illustrated in FIG. 1 that are essential to the operational se- 3,277,629 Patented Oct. l1,- 1966 ice quence. The specific structure of the various mechanisms within the machine has not been illustrated as they consist of standard parts such as motors, gears, shafts, cams, `Geneva mechanisms, etc. which, in themselves, to detail would tend more to obscure than clarify the real invention and they have not, in the interests of clarity, been completely illustrated.
rFIG. 3 is a plan view of the machine of FIG. l.
FIG. 4 is a transverse sectional vieW of the loading mechanism taken in a vertical plane substantially along line A--A of FIG. 2.
FIG. 4A is an action diagram of the orienting and loading principle.
FIG. 5 is a plan view of the area adjacent the loading station.
iFIG. 6 is a detail View of the delivery end of the capplacing means.
tFIG. 7 is a detail view of the cap-pinching means at station 7.
`FIGS. 8 and 8A are detail views of the cap spin-sealing heads located at stations 8 and 8A.
The invention is illustrated schematically in the block diagram FIG. 1 in which the stations are numbered 1 through 10 and wherein the legends 2x mean two cartridges are processed `simultaneously at the stations identied. The Magazine at station 1 may be a portable case, is preloaded with empty cartridges, horizontally disposed With their open ends toward the viewer. The magazine is placed into the Feed Hopper at station 2 and a door in the front end of the case slid open to allow the cartridges to ro-ll into the hopper and rest against the surface of a notched pick-up wheel at station 3. W'hen the wheel is indexed the cartridges find their way into the notches and are brought from the hopper to the top of the wheel (marked INDEX A in FIG. 5) where a tipper block applies downward pressure on the projecting ends of the cartridges and tips them t-o a vertical position.v
Upon being tipped to vertical position the cartridges fall into spaced pockets of an intermittently movable conveyor (here represented by the dotted line oval). On a succeeding cycle of operation two cartridges are moved to a center and purge station #i4 (marked INDEX D in FIG. 2) where the necks are centered with jets that descend into the cartridges and discharge an inert gas to displace the air. Thereafter the pair of cartridges move to a Center, iBlank Detector, and Fill station #5 (marked INDEX E in FIG. 2) where the pair is lled with a measured charge of a medicinal product. As before, each cartridge is centered and a filling needle descends into the open end and delivers i-ts charge. If either or both conveyor pockets or chucks should be empty on arrival at the filling station, there will be no centering and the filling mechanism will be latched out of operation.
After filling a pair of cartridges move .through a Cap Pick-Up station #6 (marked INDEX F and INDEX G .in FIG. 6) where each cartridge picks up `an inverted cup-shaped cap wlhile it is moving from filling station # 5 to Pinch station # 7. At the latter station (marked INDEX G in FIG. 8) the caps are pressed down on the vitals with an equalizing presser f-o'ot (which automatically compensates for vital height vibrations) and given a preliminary pinch to hold the caps captive on the cartridges during their travel to the Spin- Seal stations # 8 and 8A. Because the spinning heads rotate and reciprocate vertically and include radically movable rollers, and it has been fou-nd desirable to space the spinning heads apart and operate upon 'alternate ones of alternate pairs on each cycle (as illustrated in FIG. 8 marked INDEX H and INDEX J). Each spinning head is constructed to have a limited end'wise ii-oat and will automatically compensate for an-y variation in vial height and a common actuator may be employed to impart the vertical movement of both heads in cyclic manner.
At the Spin-Seal stations the caps are pressed down more firmly -on the cartridges and the lower skirt portions of the caps rolled neatly under the lips of the vials. In this particular embodiment lthe closing-in of the spinning rolls -is air-.actuated whereas their rotation is effected by a separate motor M2. By suitably controlling the air pressure, the tightness of the seal may also be controlled. After spin-sealing the cartridges are indexed in pairs to a Discharge and Orient station #9 (marked INDEX K in FIG. 3) where they fall in rapid succession ou-t from the bottom of the conveyor chucks onto a curved chute. The chute delivers the 'lled and sealed cartridges to -a suitable support, basket, or moving conveyor for inspection. Steps ollowing inspection, such as sterilization, coding, aliixing other elements, packaging, etc. are not intended to be a part of this invention of automatic loading, lilling, capping and sealing of cartridges containing pharmaceutical preparations.
The diagram, FIG. 1, also ilustrates .the several transmission trains to the components of the sequence. Motor M1 drives the main machine through .a variable speed mechanism VS and reduction unit RED. A first branch transmission A operating through an intermittent motion producing mechanism INT. l propels the conveyor chucks intermittently in a closed path represented by the yoval shown in dotted lines. A second branch transmission B operating through a continuously rotating cam, raises and lowers the pinching and spinning 'heads in timed relation with the indexing movements imparted to the conveyor. A third branch C operates the centering, blank detecting, and lling mechanisms including needle elevating and lowering. rDhese components are cam opera-ted and also timed with the indexing movements of the conveyor. The main drive continues through a disconnect clutch means identified as Loading Clu-tc to a second intermittent motion-producing means INT. 2 to the cartridge pick-up wheel and tipping mechanism, identified generally as Orient .and Load at station 3. The orienting and loading mechanisms are thus driven intermittently and in timed relation with the movements of the"v conveyor s-o that two cartridge-s are inserted into the chucks during the dwell period and two picked up from the feed hopper during the moving peri-od of the conveyor. Disconnecting the drive by opening .the Loading-Clutch will suspend loading and will allow the remainder of .the mechanisms to function.
As will 'be understood from the block diagram, FIG. 1, the main motor M1 has its own control means such 'as a start-stop switch, the cap-sealing ino-tor M2 has its cont-rol means, the cap-feeding mechanism at station # 6 has its control means, andthe loading-clutch has its control means. Selective operation of the several components is thereby possible. It will also be evident from the diagram that an adjustment made to the variablespeed mechanism changes the speed of the conveyor, the operation of .the centering Iand filling units, the oper-ation of raisin-g and lowering of the filling needles and spinning heads, and the loading mechanisms, all in like ratio without effecting their relative timing. 'The spinning heads at stations 8 and 8A are caused however to revolve at a constant speed and have their own motor drive, and a cap feeding mechanism when operating, also operates to supply caps at a constant rate and has its own power unit.
. It may be noted at this point that while the cartridges are guided during their orientation Ato vertical position at station # 3, they fall freely and are loosely confined in the pockets or chucks of the conveyor. As they index into the purging station #'4 the bodies of the cartridges become clamped in the chucks and their tops are steadied for centering -and needle penetration. The cartridges remain so clamped throughout the remaining processing operations until they arrive at the discharge stat-ion #9 where they are released for free fall into an underlying delivery chute.
Referring m-ore particularly to FIGS. 2 and 3 the machine comprises a main frame 15 which houses the power transmission elements. The On-O switches that control the motors M1 and M2 Kand the cap feeding unit is illustrated at 16. The variable speed control knob is illustrated at 17, the loading-clutch control handle is 1-8 and the delivery chute is 19.
The top of the main frame supports the instrumentalities that perform the proces-sing operations, in which 20 is an endless conveyor made up of a chain of V-shaped, open-sided chucks 21. The open sides of the chucks on the forward run of the conveyor are effectively closed by `a guide 1rail 22 that houses a successi-on of overlapping spring-loaded pressure applying shoes 23. 'Ihe pressure shoes project slightly into the cartridge runway and serve continuously to press the cartridge bodies tirmly into the V-p-ockets of the respective chucks.
The conveyor and conveyor-drive and -filling mechanism of this invention is a carrying forward of the arrangement shown in the patent to Cozzoli No. 2,749,688. In this instance however, open-sided V-iblocks 211 of the conveyor replace the rollers 31 of the patent. V-pockets 21a herein function as the roller V-pockets 31a of the patent, to hold the cartridges upright. Also, in the present disclosure, the conveyor chain which carries the V- block type of chuck Geneva-indexed a distance to move the pockets 21a of two (2) chucks into a given station (or tout of a given station as the case may be) on each operational cycle,y whereas in the patent the conveyor movement -is Geneva-indexed .to move one repectacle at a time into -or out of a given position. In the .present invention the spacing of the several pairs of processing devices along the line has 'been made as compact as possible, having regard to the bulk and physical requirements of such devices. In any event, however, each index movement positions two (2)' untreated cartridges into the proper respective posi-tions to be operated upon by the device at the respective stations.
The feed hopper, indicated at 24, is open at its upper end for the reception of cartridges and also at its lower end to receive 4a portion of a notched pick-up wheel 25. The notches or grooves are in the rim of the wheel parallel to the wheel axis and in pairs whose spacing equals the spacing of .the V-pockets in the conveyor. The depth of each of the grooves is approximately half the diameter of the cartridges and will receive cartridges from the bottom of the pile in the hopper as the wheel is indexed. The captive cartridges are drawn ont of the hopper from beneath an adjustable gauge-gate 24a and brought to an upper position where the pair of cartridges straddle the vertical centerline of the Wheel and there momentarily dwell. As shown in FIG. 4, the rear wall 24b of the feed hopper extends beyond the end of the piek-up wheel so that the cartridges trapped in the grooves of the wheel overhang the end of the wheel as illustrated more clearly in FIG. 4A. When so positioned the over-hanging ends underlie a ledge 26h provided by a vertically movable tipper 'block 26. The tipper block is also provided with a pai-r of vertical grooves 26a whose function is xto receive the bodies of the cartridges. As the block descends the ledge 261; engages the overhanding ends of a pair of cartridges and with downward pressure tips the cartridges from horizontal position to vertical posi-tion off the wheel. The cartridges |are received by the vertical grooves 26a and drop vertically into the V-shaiped pockets of .the conveyor chucks 21 which at that moment are directly beneath and standing stationary. The action diagram represented by FIG. 4A illustrates the sequence of the operation. The upper igure of the group represents a cartridge is stopped position at the top of -t-he wheel-and its overhanging end underlying the ledge 2Gb of the tipper block 26; The
center ligure represents the cartridge in partially tipped up position, and the b-ottom figure represents the cantridge in vertical free-falling position about to be received by the conveyor chuck 21 directly below. On the next cycle the tipper block moves upwardly yand rests, the main conveyor indexes to take the `standing cartridges out of the position just described and to bring another pair of empty chucks into cartridge-receiving position beneath the tipper block. Meanwhile the pick-up Wheel 25 has indexed to bring another pair of cartridges to the tipping station at the top of the wheel. The front Wall 214C of the hopper 24 is inwardly adjustable and carries a gauge finger 24d that overlays the wheel rim. The gauge linger serves to guide the cartridges endwise to assume uniform or constant overhang and also acts as a banrier to restrain movement of the cartridges endwise in the opposite direction.
A portion of the pick-up wheel-and-tipper drive is shown in FIG. 2 and in FIG. 4 wherein a chain sprocket receives power from m-otor M1 at a take-olf point beyond the Loading Clutch .and drives a two-arm Geneva crank 31 on a shaft 32. The Geneva crank drives its complementary star-wheel 33 on another shaft- 34 which through a chain and sprocket drive 35 indexes the pickup wheel one station (two cartridges picked up) each 'half revolution of the crank shaft 32. The other end of the crank shaft 32 carries a two-lobe cam 36 which is tracked by a cam follower mounted to a yoke piece 37. The yoke piece 3-7 mounts `an adjustable connecting rod 38 whose upper end is pivotally connected to one end of a tipper-block link 39. The link 39 is fulcrumed at 40 and is pivot-ally connected to the tipper block 26. A second parallel link 41 is pivotally connected to the tipper block and to the support 42 and maintains the tipper block in vertical position during its slightly arcuate movement. A pull spring 38a connected between the rod 38 and the top of the machine causes the camdollower on the yokeblock 37 to track the cam 36 and which also allows the tipper block to yield during downward movement if there should be any jamming at the wheel.
As also seen in FIGS. 4 and 4A a normally-stationary but laterally-adjustable guide fence 43 stands between the end face of the lpick-u-p wheel 25 and the fronts of the conveyor chucks 21 for regulating lthe size of the receiving pocket in the chucks and also for preventing the standing cartridges from leanin-g `against the wheel during their indexing movements.
As above indicated the cartridges, now upstanding in the chucks, move intermittently `along an underlying track 21a to the gassing and filling stations where they become clam-pcd by the rail 22 and pressure shoes' 2-3 and are centered and gassed two-at-a-time. (Gassing may be omitted if the package product will tolerate air in the cartridges.) After gassng, that pair of cartridge-s are moved into the iilling station # 5 Where they are detected, centered, and filled in a known manner (see for example the filling structure in Patent No. 2,749,688 issued Iune 12, 1956, to Frank I. Cozzoli and No. 2,827,997 issued Mar. 25, 1958, to the same inventor). In the present machine-we use and actuate two s-ets of detectors and centering lingers, and iilling units in the same manner as the single units shown in the aforementioned patents.
After filling, the cartridges are moved through a cappick-up station # 6 and each picks up a cap from the spring fingers 45 at the delivery end of the chute 46. The chute 46 extends rearwardly and upwardly to a bowl feeder 47 which may be of the vibratory type that continuously supplies the chute with caps properly oriented as to position for proper pick-up. The feeder operation is individually controlled as previously mentioned. FIG. 6 illustrates in greater detail the picking up action and it is believed self-explanatory. Each of the pair of cartridges picks up its cap as it indexes into a preliminary pinching head 50 at station # 7. The pinching head comprises, essentially, a vertically movable carrier 51, carried by the spinning assembly, that pivotally supports a tunnel-like block 52. Ledges 52a formed within the tunnel, press downwardly on the tops of the caps on two standing cartridges. The block 52 also carries a pair of opposed pinch blades 53 that cyclically are caused to move inwardly against the cap skirts and pinch opposite sides thereof against the cartridge necks. The pinch blades 53 are mounted to pivoted levers 54 that are spring-loaded to open position. The upper ends of the levers carry rollers that ride the surface of an endWise-rnovable cone 55. The cone is actuated by an air cylinder 56 and lever 57 and is timed with the machine to effect the pinch operation during the dwell period of the cartridges at that station after the pinching head has moved down and has applied a yielding equalizing pressure on the cap tops.
After pinching the caps, the pinch lingers are caused to open, the head 51 lifts away and the pair of cartridges are indexed to the spin-sealing stations 8 and 8A. In this embodiment of the invention the spinning heads 60, of which there are two, are spaced apart a distance equal to four conveyor-chuck spaces. Accordingly, the lead cartridge of the pair leaving the pinch station will skip the first spinning head at station # 8 and the second cartridge of that pair will come to a stop in axial alignment with the spinning head at station # 8. On the next index movement the aforesaid lead cartridge Will move and come to a stop under the second spinning head at station # 8A. The second or trailing cartridge that was acted upon at station # 8 will be missed at station # 8A With a full complement of cartridges in the pockets of the conveyor, a cartridge and cap to be spin-sealed will be positioned under each spinning head on each operating cycle and two cartridges with their caps finished-sealed will move out of the spinning stations on each index. The pressure shoes 23 in the front guide rail terminates just past the second spin-seal station 8A and thereafter cartridges stand loosely in the chucks of the conveyor. In this loose state they are indexed to the end of the underlying supporting track and drop through a hole I in the top plate into the delivery chute 19 positioned therebeneath (see FIG. 3). The chute leads to the front of the machine where the cartridges discharge two-at-a-time in horizontal position upon a suitable support, moving or stationary, that may be provided ready for .individual inspection or other processing steps.
The spinning heads 60- are detachably connected to continuously rotating spindles 61 journaled in a housing 62 and belt driven by motor M2 located in the base of the machine. T he housing is supported upon a vertically movable column 62a (FIG. 2) and is reciprocated vertically by means such as a continuously rotating cam (part of transmission B) in the base of the machine, driven by motor M1.
Referring to FIG. 8, each spinning head 60 is mounted as to have a limited axial float, herein indicated by the gap 63 between the axially movable drive spindle 61 and housing 62 and this allows for independent vertical movement to compensate for minor vari-ations in cartridge height. In brief, each head 60 is constructed to revolve around a central non-rotating spindle 64 that carries `at its lower end an adjustable cap-.seating head 65 contoured at its end to fit the top of the particular cap. The capseating head 65 applies downward pressure on the cap and keeps it from rotating and from being dragged around by the pressure of the spinning rollers 66. The spinning rollers, preferably three in each head, are journaled at the lower ends of levers 67 pivotally mounted in each spinning head body. The upper ends of the levers 67 carry antifriction rollers that ride the surface of an axially shiftable cone 68. Each `cone is shifted axially by means of a yoke lever 69 that is connected to and responds to the action of an air cylinder 70. The air cylinder is oontrolled by a cam-actuated valve in the base of the machine,
the cam being driven continuously and in timed relation with the required operational cycle, as follows: the cartridges are indexed into the spin-sealing stations, the spinning heads 6G lower together and settle on the caps of their respective cartridges, after which the air cylinders 70 are actuated to bring the revolving spinning rollers 66 radially into engagement with the skirts of the caps` Continued inward movement of the revolving rollers 66 causes a rolling-in of `the cap skirt neatly under the lip at the neck of the cartridge to form the finished seal. By appropriately controlling the air pressure to cylinder 70, the degree of down pressure applied to the cap of the cartridge may he controlled as well as the radial pressure on the rolled-in portion of the cap skirt. The relation of Vthe down pressure to radial pressure is in part a function of the angle `of the cone 68 and the line pressure, and as modified by the axial float provided at the point 63 of each drive spindle.
The foregoing presupposes `a machine set-up for processing cartridges of a particular dimension as to height and diameter. Cartridges of a different height may be processed by shifting the gauge nger 24d at the feed hopper laterally to suit the length of the cartridge, and by raising and lowering the filling needles and centering devices at stations # 4 and #5; the cap chute and bowl feeder at station # 6; and the drive housing that carries the pinching head and spinning heads-on its supporting columns at stations # 7, 8 and 8A. If .a different diameter cartridge is to be run, the fence 43 and guide rail 22 are adjusted laterally, as Well as the lling needles and centering devices at stations # 4 and #5, the cap chute and feeder mechanisms at station # 6 and the drive housing at stations # 8 and 8A so that these components may function properly with relation to the changed centerline of the new cartridges conned in the V-pockets of the conveyor.
