First and Hans Grotewold, Philadelphia, Pa., asslgnors to Stokes and Smith Company, Summerdale, Pa., a corporation of Pennsylvania Application November 16, 1939, Serial No. 304,678 13 Claims. (Cl. 93-6) Our invention relates to systems for feeding and filling cartons.

In accordance with our invention, cartons are removed from. a stack thereof and delivered to a conveyor which transports them through a filling station with control of feed of cartons 'from the stack to the conveyor effected in dependence upon the amount of filling, in each of the successive cartons, lying between predeteritself of, or transport to their proper destination, those cartons which have received sufilcient filling.

Further in accordance with our invention, the

cartons, while flattened or collapsed, are in succession removed from a stack thereof by a gripper, preferably of the suction type, which so positions them that they are opened, in preparation for filling, by their engagement with abutments onthe conveyor; more particularly, the cartons are transferred to pockets or recesses provided on the conveyor by a member reciproeating lengthwise of the stack.

Further in accordance with our invention, upon removal of collapsed cartons from the forward end of the stack, the stack is advanced step by step by mechanism comprising a one-way clutch having an oscillating driving member which for feed of the stack is free to follow the movements of a reciprocating actuator to which it is resiliently coupled, preferably by an elastic fluid, and which driving member is precluded from following aforesaid movements of the actuator by a control member engaged by the forward end of the stack upon arrival of its forward end at a predetermined position.

Our invention further resides in the features of construction, combination, and arrangement hereinafter described and claimed.

For an understanding of our invention, reference is to be had to the accompanying drawings, in which:

Fig. 7, in perspec tive, with parts omitted and with parts broken away, illustrates ejector mechanism controlled by the apparatus shown in Fig. 6.

Referring to Fig. 1 which exemplifies operations performed upon cartons by a machine generally of the type disclosed in United States Letters Patent No. 1,527,050 to Delamere et al., the cartons C are, in turn, removed from the stack S by mechanism hereinafter more fully described, and delivered to an endless conveyor comprising a belt 2 (Figs. 6, 7) which passes about the drums 3, 25, Fig. 1, and from which extend blocks l forming a series of pockets or recesses for reception of the cartons. As each carton moves beyond the position of carton 20, Fig. 1, its bot tom flaps CI and C2 are turned upwardly and inwardly, and its flaps C3, C4 are bent upwardly and outwardly so that, as the carton moves toward and beyond the position of carton 40, Fig. 1, adhesive is applied by the roller AB to the under face of the four fiaps.

A preferred arrangement for supplying adhesive to the roll AB, and also to roll AT which, as hereinafter described, applies adhesive to the top flaps C5-C8 of the cartons, is disclosed in our copending application Serial No. 302,806, filed November 4, 1939.

As each carton moves beyond the adhesiveapplying roll AB, the flap C3 is turned downwardly and then upwardly into adhesive engagement with flaps Cl, C2 and finally the flap C4 is moved into overlying adhesive engagement with panel C3.

Each of the cartons with its bottom thus closed then, in turn, passes through a filling station F for filling by mechanism preferably of the type disclosed and claimed in our copending application Serial No. 302,807, filed November 4, 1939. During passage of the cartons through the filling station, the open upper end of each carton is aligned with a filling snout 4 depending from the rotating plate at a predetermined position of each carton, a. gate 6 supported by plate 5 for movement between a filling snout 4 and its associated measuring flask I swings outwardly to allow a charge of filling material within the flask to fall into the carton below it.

As each, carton moves beyond the filling station F, the quantity of material in each of them is checked by a device L, hereinafter more fully described, and if the filling in any carton is in error in amount, more particularly insuflicient, that carton, preferably at a subsequent position, is ejected from the conveyor by ejector mechanism E, hereinafter more fully described. Preferably, the mechanism for detecting error in quantity of material in the cartons also controls the feeding of cartons from stack S, so that when the device L detects improper amount of filling of cartons, supply of additional cartons to the conveyor 2 is interrupted.

Those cartons which are not ejected from the conveyor 2 continue to move therewith toward the adhesive-applying roll AT which applies a coating of adhesive to their top panels C5-C8 which, prior to arrival of each carton at roll AT, have been bent to the position shown, carton I6C. Thereafter, the flaps C1, C8 of each carton are folded over into adhesive attachment with each other and flaps C5, C6 to form the closed top of the carton.

The completed cartons are diverted from the conveyor belt 2 and turned through an angle of substantially 90 for travel broadside with respect to each other (cartons 22C, 23C, etc.) between belts, not shown, which apply pressure, for suitably long time, to the closed ends of the cartons during their travel to a discharge point. A preferred arrangement for turning the cartons and applying pressure to their ends during setting of the adhesive on the flaps is disclosed and claimed in our aforesaid copending application Serial No. 302,806.

Referring to Fig. 2, the stack of flattened cartons is disposed upon a support or plate 8 with the front end of the stack adjacent a region where the conveyor belt 2 passes about the periphery of drum 25. The knife 9 for entering each flattened carton is adjustably secured, as by nut III, to member II pivotally mounted at I2 to the upper end of the vertically reciprocable bar I3, or preferably, as indicated, to the adjustable extension I3A thereof. The spring I4 between the member II and its support I3A biases the knife 9 against the front face of the stack yet permits it to yield when the suction gripper device hereinafter described pulls the end carton of the stack toward the position shown in Fig. 2. When the cartons are of the type shown, with flaps C5,

'C6 shorter than the flaps C1, C8, the knife 9;

for uppermost position of its reciprocating support I3, bears against panel C8 at that region thereof exposed above the shorter flap C6. As the knife 3 descends, it swings the side SI of the carton in counterclockwise direction, as viewed in Fig. 2, and positively separates the sides SI, S2, S3 notwithstanding any inadvertent bond due, for example, to adhesive which may have been, during manufacture of the flattened carton, squeezed out of the usual seam between the sides SI, $2. This preliminary opening of the carton, which may often be dispensed with, insures opening of the cartons by the mechanism hereinafter described.

The reciprocating bar I3 which supports the for connection, by link I6, to the lever I1 upon which is mounted the cam follower I8 continuously engaged by the periphery of the cam IS on shaft 20 continuously driven from the drive shaft of conveyor belt 2 at such speed that cam l3 makes one revolution during advance of a carton by belt 2 through a distance corresponding with a distance between the center lines of adjacent cartons.

The knife 9 and its support are thus positively moved upwardly; however, the downward movement of the knife is preferably effected by biasing means capable of yielding in event the knife 9 is jammed in its descent, as by improper positioning of the cartons in the stack; for example, if the front face of the stack becomes inclined, the obstruction offered by the stack to the descending knife might seriously damage the mechanism. In the exemplary arrangement disclosed, the downward movement of the knife 9 is effected by spring 2I positioned between the guide 22 extending upwardly from the base of the housing I5 and the adjustable stops or nuts 23 on rod 24 24 which extends through the guide 22 for connection to one end of a chain 25 which passes about small sprocket 23 and is attached thereto. The large sprocket 21, also attached to shaft 28, is connected to one end of chain 29 which passes over an idler sprocket 30 for connection at 3| to the lower end of the reciprocable bar I3. Accordingly, the cam I9 in moving bar I3 upwardly effects compression of spring 2| for storage of a limited amount of energy to be expended in effecting downward movement of knife 9.

The cartons are in turn removed from stack S by suction-feed devices 32 attached to the hollow shaft 33 for movement therewith as it is oscillated, in timed relation to conveyor 2, by the cam the link 38 extending to the arm 39 attached to knife 3 extends downwardly into the housing I5 76 aforesaid hollow shaft 33. The spring 40 connected to link 38 biases the suction devices 32 toward engagement with the end carton of the stack S. At its lower end the hollow shaft 33 is connected, as by hose H, to a suitable source of suction, such as a suction pump, and intermediate its ends shaft 33 is provided with a relief valve 42, biased to closed position by spring 43, and opened by engagement with a stationary stop structure 44 when the suction devices 32 have removed a carton from the stack.

The opening of valve 42 occurs substantially concurrently with movement of the suction heads 32 in counterclockwise direction by or between the members 45 which serve as stops engaging the removed carton positively to strip it from the suction heads. The leading face of each of the conveyor blocks I is serrated to catch or engage the corner or edge of each carton between its panels S2, S3 and so by its movement coacts with the suction heads 32 to open the carton, for subsequent reception of filling, before or as it is transferred into the conveyor pocket.

Conveyor 2 is so timed that substantially concurrently with withdrawal of a carton by the suction feeders 32, a pocket or recess formed by a pair of conveyor blocks I is in position to receive the carton. Transfer of the open carton into this pocket or recess is effected by pusher mechanism comprising the horizontally reciprocating bar 46 slidably received by guides, not shown, at-

'pivotally connected to arm 6| tached to the housing IS. The bar 45 is connected by link 41 to bell-crank lever 48 pivotally supported from wall structure of housing l and connected by a link 49 to crank-pin 58 extending from the face of gear 5| driven by gear 52 on the shaft 28.

For each rotation of shaft 28, bar 46 reciprocates to transfer a carton which has been separated from the end of stack S into an empty pocket of the conveyor 2,

The feed of cartons from stack S may be in-' terrupted at any time, without interruption of operation of the other parts of the machine, by swinging a control handle 51 in clockwise direction from the position shown in Fig. 2, to position a latch 58 in the path of shoulder 59 of the member 68 attached to shaft 33. The angular disposition of member 68 on shaft 33 is such that the latch 58 will ride off shoulder 59 and fall behind it when the suction devices 33 are sub-- stantially away from the end of the stack of cartons S; latch 58 therefore restrains the devices 32 from movement by spring 38 toward the stack S. When latch 58 is released, as by return of handle 57 to the position shown in Fig. 2, the spring 48 is effective to reestablish normal operation of the suction heads 32 by cam 34.

Preferably the mechanical connections between the control handle 51 and the latch 58 comprise a toggle formed by the arm 6|, attached to the shaft 62 of latch member 58, and the arm 63 and slidable through the hub 64 of the control lever 51. The spring 65 is compressed when the control member 51 is moved in either direction to swing the arms 6|, 63 over center to break the toggle; stops 66 and 6! limit movement of the latch member 58 by spring 65 in both directions. When member 58 is in engagement with stop 66, it is substantially away from the member 68 and does not engage member 68, for any angular position thereof, until handle 51 has been moved sufficiently to break the toggle.

When it is desired to interrupt removal of cartons from stack S, the control lever 51 may be operated at any time in a revolution of shaft 28, yet the carton feed will not actually stop until there has been completed the removal and transfer of any carton whose removal from the stack has been initiated.

The control handle 51 may be operated at any time to resume feed of the cartons, but the resumption of feed will not actually begin until the conveyor 2, knife 9, and pusher bar 46, which have continued to operate, assume, with respect to suction heads 32, their proper positions for normal operation.

The latch 58 is also subject to the control of an electromagnetic device 68A whose armature or core member 68B is connected to the knee of the toggle 6|, 63 by the link 68. As hereinafter. more fully described, the solenoid 68A is energized, when a carton receives insufilcient'amount of filling material, to move the toggle arms 6|, 63 over center and so bias the latch 58 for interruption of the carton feed, as above explained in connection with manipulation of the manually operable control lever 51.

In Fig. 4, there is shown the mechanism for feeding the stack of cartons to position for successive removal of the cartons by the suctiongrippers 32. The rear carton of the stack is engaged by a plate 89 supported from the weighted member 18 resting upon and advanced by the chains ll. Preferably the engagement between the chains ii and member I8 is merely a frictional engagement afforded, for example, by a facing 12 of sponge-rubber or equivalent material attached to the under face of member 18.

The sides of the stack are engaged by uide bars 13 to whose forward ends are attached, as

by bolts 14, the adjustable stops '5 whose ends' spring arm 18, clears the top flap Cl, because of a notch therein, and engages the flap C8.

The spring arm 18 is adjustably secured, as by screw 19, to a bracket 88 which extends over the top of the stack and to which may be attached a spring member 8| for pressing against the top of the stack, particularly near the front end thereof.

As the stack is depleted by the automatic removal of cartons from the front end thereof, additional cartons are added to the rear of the stack by an operator who need simply lift off or slide back the member 18 and insert additiona1 cartons between the plate 69 of member 18 and the rear face of the cartons already in place.

Feed of the stack S is effected by the intermittent actuation of the chains II which pass over the sprockets 83, 83 on shaft 84 to which is attached the driven member 85 of a' ratchet or one-way clutch mechanism; i. e., a clutch effective for rotating driven member 85 during only one direction of rotation of the driving member 86, which driving member 86 is attached to or formed with an arm 82 connected by link 81 to a piston 88 slidable within a cylinder 89 attached to wall structure of housing l5. Piston 98, slidable within the cylinder 89, is connected by link 9| to arm 92 pivoted at 93 to the wall structure of the housing l5 and carrying a camfollower received by cam track 95 of the cam 98 attached to the continuously rotating shaft 28. As piston 98 is moved downwardly, the suction created within the cylinder 89 causes a follow-up movement of the piston 88. The resultant movement of the driving clutch member 86 in clockwise direction is transmitted by the rollers 98 to the driven clutch member 85.

Upon upward movement of piston 98, the air within the cylinder 89 is compressed and piston 88 is raised, with consequent movement of the clutch member 86 in reverse direction. This reverse movement of member 86 is not transmitted to the conveyor chains through the clutch rollers 98 and driven clutch member 85. Excess pres sure within the cylinder 89 is avoided by a simple relief valve comprising, for example, a light spring member 99 biased by its own resiliency to close a port extending through the piston '88.

Thus, for each revolution of shaft 28 the conveyor chains 1|, 1| advance by a small amount or short step to advance the stack S.

The extent to which the conveyor chains are moved for each revolution of shaft 28 can be controlled by adjustment of the stop I88 which engages the member l8! attached t and movable with the driving clutch member 86. The

position of stop I88 determines the lowermost position to which piston 88 can be moved by suetion created in cylinder 89; in other words, stop I provides means for adjusting the stroke of piston 88, and therefore adjustment of the increment of advance of chains 1I, notwithstanding constancy of the length of stroke of piston 90.

Interruption of operation of the stack-feeding chains H is controlled by a pivoted latch I02 which can be swung to position its shoulder I03 in the path of member IOI attached to the driving clutch member 86. When latch member I02 is swung in clockwise direction from its position shown in Fig. 4, so to engage member IN, the

piston 90 reciprocates idly without effecting corresponding reciprocation of the piston 68. The latch I02 may be controlled automatically in response to arrival of the front carton of the stack at the desired position for its removal by the suction heads 32; for example, in the particular arrangement disclosed, there is provided the feeler I04 attached to shaft I05 and biased, as by a suitably light spring I06, to engage the front of the stack. When the arm I04 by engagement by' the front end of the advancing stack is sufficiently moved in opposition to spring I06, the

arm I01, attached to shaft I05, effects operation of a switch I08 to energize solenoid I09 whose armature or core H0 is connected by link III to arm II2 attached to shaft II3 of aforesaid latch member I02; movement of armature H0 in response to energization of solenoid I09 posiu tlons latch member I02 in the path of the extension IOI of the clutch member 86 and so precludes further feed of the stack. The switch I08, though shown conventionally a of the pushbutton type, preferably is of known type requiring for'operation of its contacts only a very small force and an operating member moving through only a few thousandths of an inch.

When switch I08 is opened, the solenoid I09 is deenergized and spring I I2A connected between I02 and armature IIO to their positions shown in Fig. 4.

, In the modification shown in Fig. 5, the cartons, instead of being directly transferred from the stack S to the conveyor 2, are delivered by the carton-feeding mechanism shown in Figs. 2 and 3 to an intermediate conveyor member comprising a drum 25A having extending therefrom blocks IA providing recesses or pockets to receive the cartons which travel with the drum 25A until deflected therefrom by a stripper plate I I4 which coacts with the members II5 to form a gate through which each carton in turn is forced to pass between the pressing rolls H6, H6 rotating transferred from conveyor 2 to another machine for filling; when the cartons remain in conveyor 2 for the filling and closing operations shown in Fig. 1, the simpler arrangement shown in Fig. 3 is usually satisfactory for most kinds of cartons.

The device L, Fig. 6, for detecting whether or not the cartons have received proper amount of filling, comprises a .disc II1 having a plurality of circumferentially spaced pins II8 extending from one face thereof. Each pin passes through an elongated slot H9 in a feeler member I20 maintained in vertical position by its weighted feeling end I2I. From the upper end of each member I20 there extends a member comprising shaft I23 and roller I24 thereon for operating electric switch I35 under circumstances hereinafter discussed.

Disc H1 is mounted upon shaft I25 whose opposite ends are respectively received by slides I26 and I21 between which the row of filled cartons is transported by conveyor belt 2. The slide I26 is guided by bracket I28 extending upwardly from the bridge I29 which extends between the conveyor drums 3 and 25. With locking screw I30 released, the slides I26 and I21 may be raised or lowered by adjustment of screw I3I so to predetermine the lowest point of the path of travel of the weighted ends I2I of the members I20. From the lower end of slide I21 extends, bar I32 slidably received by bracket I33 which extends beneath belt I34 to the bridge member I29. 1

Upon the slide I21 is mounted a switch I35 which is closed to energize solenoid 68A of the carton-feed mechanism (Fig. 3) when one of the members I20 enters a carton which is insufliciently filled. The switch I35 which may be of any desired construction is mechanically connected to the member I36 pivotally mounted upon 40 arm II2 and pin 5 is efiective to return latch In passing from conveyor 25A to conveyor belt slide I21 and biased by spring I31 into the path of the rollers I24.

, Assuming the cartons are in proper amount filled, each of the members I20 as it enters a carton engages the filling to hold roller I24 suffi- '45 ciently high to prevent its engagement with member I36. When, however, a carton is insufficiently filled (carton CI3, Fig. 6), the member I20 which enters it moves downwardly beyond the usual position corresponding with proper amount of filling, so that roller I24 engages member I36 and thereby rocks it sufiiciently to effect closure of switch I35. The resulting energization of solenoid 68A, Fig. 3, interrupts the feed of cartons from stack S to the conveyor 2.

To prevent the detector L from repeatedly stopping the feed of cartons when the conveyor pockets passing beneath disc II1 are empty of cartons, as at the beginning of a run for example, there is provided a second switch I38 electrically in series with switch I35 to prevent energization of solenoid 68A by closure of switch I35 in event such closure is due to absence of a carton rather than insufficient or other improper filling of a carton. Switch I38, in the example disclosed, comprises an arm I39 which, when engaged by a carton whose sufficiency of filling is being checked, holds the switch contacts closed in opposition to a biasing spring I40; if no carton is present, spring I 40 opens switch I38 and so renders closure of switch I35 ineffective to energize solenoid 68A.

. For detecting over-filling or too great an amount of filling, the positions of member I36 and member I24 are relatively reversed, so to insufliciently filled by control of ejector mechanism E, preferably constructed as shown in Fig.

7. The ejector comprises two members I 4|, I42

normally to one side of the path of travel of the cartons and mounted to move parallel to each other respectively above and below the belt 2 to engage a carton to be ejected both near its top and bottom.

Intermediate their ends, the members I4I, I42 are pivotally connected to arms I43, I44 attached to the vertically mounted shaft I45; at its end more remote from belt 2, member I is pivotally connected to arm I46 attached to shaft I41 to which is also attached a bell-crank lever I48 one of whose arms is pivotally connected to ejector member I 42 and the other of whose arms is pivotally connected to a rod I49. To shaft H1 is also attached arm I50 carrying a follower ISI for engagement with the cam I52 on shaft I53 timed to make one revolution while conveyor 2 is advancing the cartons through a distance correspending with the distance between the center lines of a pair of adjacent cartons. Such timing may be effected by suitable gearing between shaft I53 (corresponding with shaft I of our aforesaid copending applications) and the drive shaft of conveyor drum 3.

With the parts in their positions shown in Fig. 7, the ejector members I4I, I42 are restrained against movement by the powerful spring I54 by engagement of stop member I55, on operating rod I49, with the latch member I56 connected by link I'I to the core or armature I58 of solenoid I59.

As thus far described, so long as latch member I56 remains in the position shownin Fig. '7, spring I54 remains compressed and does not operate ejector members HI, I 42. When, however, solenoid I59 is energized by closure of switch I35, Fig. 6, in response to detection of an insufficiently filled carton, latch I56 is moved downwardly, in opposition to biasing spring I60. out of the path of stop member I55 and is locked in its lower position by a second latching member I6I biased to its latching position by spring I62.

The ejector members I 4|, I42, however, do not operate immediately upon energization of solenoid I59: they remain in their retracted position until the insufficiently filled carton has moved beyond the light-weight detector and into the path of ejector members I4I, I42, whereupon the fall in cam I52 permits spring I54 abruptly to actuate members I4I, I42 and so forcibly eject the improperly filled carton from conveyor 2 through a gap in theside guides 54B.

At or near the end of forward movement of the ejector, the second latch member I6I is released from engagement with latch member I56 by the adjustable stop I63, whereupon latch member I56 is moved by spring I60 upwardly into engagement with the under face of extension I64 of stop member I55 on rod I49. As rod I49 is returned to its original position by the rise of cam I52, latch I56 slides along the under face of extension I64 and eventually passes beyond the extension I64, whereupon spring I60 eflects further upward movement of latch I56 to position predetermined by stop I65.

To avoid need for solenoid I59 to overcome the large frictional resistance otherwise existing between the latch .156 and stop I55, the cam I52 thrdughout the angle A is eflective to hold stop I 55 slightly away from engagement with latch I56 and it is within this angle that switch I35 of the light-weight detector operates, if at all, to energize solenoid I59.
