O'LE ICK M 1 ATTORNEY United States Patent ration of New Jersey Filed Dec. 14, 1959, Ser. No. 859,284 20 Claims. (Cl. 113-1) This invention relates to machines of the general nature described in Patents No. 2,216,733 dated October 8, 1940, No. 2,300,099 dated October 27, 1942, No. 2,861,529 dated November 25, 1958, and No. 2,892,430 dated June 30, 1959.

The machine of this invention is especially intended for the handling of pouring spouts of the general type disclosed in Patents Nos. 1,966,284 and 2,011,434 dated July 10, 1934, and August 13, 1935, respectively, although the machine embodying the present invention may be utilized for inserting other types of pouring spouts into other containers.

Machines of this type generally include means whereby at one or more stations the spouts in fiat blank form are fed successively, the blanks are bent to form body portions and sector-shaped wings in angular relation thereto, prongs are stamped up from the body portion of the spouts, and the containers are fed past said station or stations, the completed spouts being inserted into and secured to the walls of the containers as the containers move past said stations.

The machine described in Patent No. 2,216,733 includes mandrels mounted on a turret that are inserted into open upper ends of containers with a snug frictional fit and the containers are carried by the mandrels to the station at which the spouts are inserted during rotation of the turret, into the containers; and the mandrels carry anvils that cooperate with a spout-inserting member or ram for clinching the prongs of the spouts on the walls of the containers.

The machine of Patent No. 2,892,430 includes a linear conveyor for moving the containers to and from the spout-inserting station and the anvil is moved partially into the container into abutting relation to a container flap thereof that is to receiver the spout, while the spoutpushing member or ram is mounted on the frame of the machine in juxtaposed relation to the anvil so that said flap is received between the anvil and the ram.

In both of these patented machines, the spout-pushing member or ram and the anvil move momentarily synchronously with each container with a reciprocating or back and forth motion, and time is lost in the return motion of the ram and anvil, and one object of the invention is to provide a machine to eliminate this loss if possible so that the number of containers into which spouts may be inserted per unit of time may be increased.

Another object is to provide such a machine wherein the containers shall be moved continuously in one direction in a predetermined path in spaced succession or file formation, and there shall be a plurality of spout transfer and inserting units also movable continuously in spaced or file formation in the same direction so as to pick up spouts at spout-forming stations and transfer the spouts in succession to a predetermined point in juxtaposition to the containers and momentarily move synchronously with the containers, during which movement each spout shall be inserted into the portion of a container wall that is to receive the spout and thereafter said transfer units shall return in the same direction to the spout-forming station and pick up another spout.

It is a further object of the invention to provide such a machine wherein each spout transfer and inserting unit ice shall include a spout carrier, a ram for pushing the spout from the carrier into the container wall from the outer side thereof, and an anvil cooperative with the ram movable into and out of juxtaposition to the ram at the other side of the container wall, said anvil, spout carrier and ram being movable together as a unit as described and independently of each other during spout-inserting operations.

A further object of the invention is to provide such a machine wherein the spout carrier and ram shall be associated with each other so that the carrier will pick up the spout at the spout-forming station and move it into proper relation to the container wall and also into proper relation to the ram and to the anvil for insertion of the spout into the container wall.

In the operation of the spout forming and feeding mechanism, a completed spout is projected upwardly from the mechanism at the upper end thereof and in integral relation to the strip of spout blanks, the spouts being fed step by step by intermittent movement of the blank upwardly through the forming dies; and the completed spouts are severed from said strip of blanks by a cutter operable in timed relation to the feed of the spouts.

Further objects of the invention are to provide a novel and improved spout carrier which shall frictionally engage the completed spout prior to the severance of the spout from the blank strip and carry the spout from said forming mechanism to a container into which the spout is to be inserted; and to provide a novel and improved combination of such a carrier and a spout-inserting mechanism including a ram whereby the spout shall be accurately positioned by the carrier in proper relation to the container wall portion and the ram shall push the spout from the carrier and into said container wall portion.

Still another object is to provide novel and improved means in combination with said carrier for firmly pushing the spout therein after the spout has been severed from the blank strip.

It is a further object of the invention to provide in such a machine a plurality of spout-forming mechanisms and a plurality of spout carrier, inserting and anvil units moveable in timed relation so that one spout-forming mechanism will supply spouts for certain of the carrying, inserting and anvil units, while the other forming mechanism will supply spouts for alternate carrier, inserting and anvil units.

Other objects, advantages and results of the invention will be brought out by the following description in conjunction with the following drawings in which:

FIGURE 26 is a similar view approximately on the plane of the line 2626 of FIGURE 6, showing the spout completely inserted into and frictionally held in the carrier.

For the purpose of illustrating the principles of the invention, flle spout herein contemplated comprises a body portion a, prongs b on the body portion to penetrate and be clinched upon the container wall for securing the spout therein, and wings or flanges c to move in the pouring opening of the container as the spout is moved from closed to open position. As best shown in FIGURE 25, the spout wings c normally and initially diverge or flare away from each other and from the body portion a and are initially inherently resilient, and of course, the flanges are angularly related to each other forming and feeding mechanisms.

in the same way in which the longitudinal edges a of the body portion a are inclined to each other as shown in FIGURES 8 and 26.

Specifically describing the illustrated embodiment of the invention, the reference character A generally designates a conveyor for the containers B which are shown as comprising rectangular boxes having the usual side and end walls d and e, respectively, side flaps f and end flaps g. In accordance with the invention the containers are disposed on the conveyor in uniformly spaced apart relation and in file formation, the containers being accurately spaced apart by blocks C that are connected to a chain D that is driven longitudinally in any suitable manner, for example over sprockets. The blocks C and the containers B between them are slidable continuously in one direction in a predetermined path, on rails E which are mounted on a frame portion F, and the spout is to be inserted into a special zone of one of the end walls the plane of which is perpendicular to said path of movement of the containers. The blocks and containers are constrained to move in a straight line by lower guide rails and upper guide rails H that are secured on the frame portion F.

The conveyor moves the containers from a source of supply to a point intermediate the length of the conveyor that may be designated a spout-inserting station I, and as the conveyors move to the station I, one of the side flaps of each container is forced downwardly into approximately a horizontal position by a rod J beneath which the flap relatively slidably passes as best shown in FIGURES 1-4. After the containers have passed the spout-inserting station I, they slide over and along another rod K which swings the fiaps back to their normal vertical position in line with the corresponding side wall so that the container is ready for passage through a filling machine.

Coacting with the conveyor is a spout-carrying, spoutinserting and anvil mechanism generally designated L which receives finished spouts M from two spout-forming mechanisms N and O that may be of any suitable construction, preferably of the general type shown in the above mentioned Patents No. 2,216,733, No. 2,300,099, No. 2,861,529 and No. 2,892,430. The mechanism L includes a plurality of spout transfer and inserting units P each of which includes a spout carrier, spout-inserting ram and an anvil, and said units are moved continuously in spaced apart or file formation through a predetermined path a portion of which adjacent the spout-inserting station I is parallel to the path of movement of the containers.

The number of spout transfer and inserting units may be varied as desired, as may also the number of spout- The drawings herein show nine of the units P and two of the spout-forming and feeding units N and O. The units P are so spaced from each other and the spout-forming mechanisms are so spaced apart the spout carrier of certain of the units will pick up spouts from one of the forming and feeding mechanisms while other spout carriers will pick up spouts from the other forming and feeding mechanism. For example, as shown in FIGURE 1, the unit designated P1 is loaded with a spout that was picked up from the forming and feeding mechanism N, and the unit P2 is empty but will pick up a spout from the forming and feeding mechanism 0, while the unit P3 is about to pick up a spout from the forming and feeding mechanism N.

Generally describing the operation of the machine, a strip of spout blanks comprising flat spout blanks h connected in end-to-end relation is fed step by step to successively locate the blanks in proper relation to dies i and j (FIGURES 6, 7 and 8) which bend the sector-shaped Wings 0 of each spout relatively to the body portion a and also form the prongs b in the body portion, after which the completed spout at the leading end of the blank stripis projected into a position to be engaged by the spout carrier of one. of the units P. Then one of the carriers 5 moves into engagement with the spout, and in successive steps the spout is severed from the blank strip, the unit P of which the carrier forms a part moves with the spout therein to the spout-inserting station where the carrier is projected into the space between two containers B, and the anvil is moved inwardly of the container in juxtaposed position to one side of the portion of the container to receive the spout, in this instance, an end wall e as shown at the top of FIGURE 1, right hand side of FIGURE 2 and in FIGURE 21, whereupon the ram is actuated to force the flanges c of the spout through the container wall as shown in FIGURE 22 after which the ram is retracted .in the carrier, the anvil is raised out of the container and the carrier and anvil are withdrawn from between the containers, it being understood that the unit P moves vcontinuously synchronously With the container conveyor and in a path parallel to the path of movement of the container during the spout-inserting operation. The said unit continues to move along its predetermined path toward vthe corresponding spout-forming mechanism to pick up another spout, carrying it to another conveyor and insert it into a wall of another container. It will be understood that the spouts are formed and projected into the path of movement of the spout carriers in proper timed relation to the movement of the spout carriers, the spout blank being shown as fed step by step by a mechanism known in the above mentioned patents and generally designated .k

herein that is actuated by a cam m on a drive shaft 1 that also has a cam 11 thereon which actuates the die. One die icomprises a cutting member i that cooperates with a cutting edge j (FIGURES 6 and 7) for severing the spout from the blank strip.

The two spout-forming mechanisms N and 'O are simultaneously driven by a chain and sprocket connection with a maindrive shaft Q (FIGURES 3 and 4), said connectionbeing shown as comprising a sprocket on each shaft .1, an idler sprocket p journaled on the frame G of the machine, a sprocket q on the main drive shaft Q, and a chain -r that passes over said sprockets.

The main drive shaft 'Q is of course journaled in the main frame G and driven by any suitable source of power through beveledgearing S; and the units P are moved by said shaft through the instrumentality of the upper and lower chains T and T that pass around sprockets U and U and V andV' on the shaft 'Q and on a counter shaft W, respectively, to which the units P are connected by the respective brackets X and X at equidistantly spaced points along the length of the upper and lower chains T and T.

While the mechanism L and the units P may be constructed in different ways, for the purpose of illustration each unit is shown as comprising a rectangular support .plate 1 to the rear side of which at its upper and lower ends are connected the brackets X and X. 'The plate normally stands in a vertical plane and has a pair of support rollers'2 journaled on said side thereof at its lower end, anda pair of guide rollers 3 journaled on vertical axes on the upper edge of the plate as best shown in FIGURES and 13. The rollers 2 run in a track which includes two parallel grooved sections 4 each parallel to one reach of the chains U and U', one section being juxtaposed to the spout-formingmechanism N and O and the othersection being located in juxtaposition to the conveyor A or the path of movement of the containers. At the ends of the grooved :sections 4 are arcuately curved sections 5 that 'have'flat top surfaces to permit some lateral movement "of the rollers relative to the track as the unitsmove along said curvedportions.

The upper guide rollers '3 run in a continuously grooved track 6 that has two parallel portions 7 each disposed above and approximately parallel to one of the sections 4 of the lower track, and the ends of the parallel portions 7 merge into ar-cuate or curved portions 8 of a diameter somewhat greater'than the distance between the parallel sections 7 to compensate for the swinging movement .of the 6 plates 1 as they run through the arcuately curved portions 8.

FIGURE 1 shows all of the units P in top plan while in FIGURE 4 only one of the units is shown completely in plan view, portions of all the other units having been broken away or omitted for clearness in illustration; and FIGURE 13 shows one of the units in perspective with portions broken away.

Each support plate 1 has an opening therethrough in which is mounted a split tubular guide bracket 9 wherein is slidable a U-shaped mount 10 which carries the spout carrier generally designated 11, the ram or spout pusher generally designated 12, and the anvil generally designated 13.

Generally describing the operation of the units P, as the units pass along the straight sections 4 and 7 of the tracks that are juxtaposed to the spout-forming and feeding mechanisms, the spout carriers first are positioned so as to pick up the completed spouts at the upper ends of the spout blank strips, and the respective anvils are first and normally held in position to clear the spouts and the containers; and as the units move along the other straight sections of the tracks juxtaposed to the container conveyor, synchronously with the movement of the containers, the respective mounts 10 are actuated to move the corresponding carriers, rams and anvils transversely of the path of movement of the containers so that the spout carrier of each unit is projected between two adjacent containers in juxtaposition to the wall of one container and the corresponding anvil is 'at the same time projected into a position above the container and at the opposite side of said wall, whereupon the anvil is swung downwardly into the container close to said wall and immediately thereafter the spout pusher or ram is actuated to push the spout from the carrier through said container wall and cause a clinching of the spout prongs on the container wall, as shown in FIGURES 20-23. Then the anvil 'is withdrawn from the container, the ram is retracted to its original position, the mount is actuated to return the carrier, ram and anvil to their first-mentioned positions and the whole unit continues in its path of movement to the spout-forming and feeding mechanism to pick up the next spout.

More specifically describing the construction, each guide bracket 9 has two horizontal guide grooves 14 that extend perpendicularly to the path of movement of the units P, and each arm of the U-shaped mount 10 has a flange 15 slidably mounted in one of said guide grooves. The mount 10 has an arm 16 on which are two horizontally spaced rollers 17 journaled on vertical axes and receiving between them a cam track 18 fixed on the machine frame G (FIGURES l, 3 and 5) for reciprocating the mount in the guide bracket'in directions perpendicular to the path of movements of the units to move the anvil and spout carrier from their spout pick-up posit-ions to their spout-inserting positions and vice versa.

Projecting from the mount at the side thereof opposite the rollers 17 'is the spout carrier 11 that has a horizontal slot 19 therein opening through the underside thereof and of across-sectional shape approximatelycorresponding to the cross-sectional shape of the spout as best shown in FIGURES 5 and 8, the side walls 19 of the slot being inclined-withrespectto each other at an angle approximately corresponding to the angular relation of the resilient \v-ings c-of the spoutso thatsaid wings may'yieldingly frictionally engage the side walls of the slot at the front end thereof for rleasably holding the spout in the spout carrier.

A head block 20 of the spout pusher or ram 12 is slidably mounted in said slot 19 and normally disposed at the rear or trailing'endthereof. The block has acrosssectional shape approximately corresponding to that of the slot and has a-pin and slot connection 2 1 'with one end of a lever 22 which ispivotally mounted intermediate its ends "at 23 on the mount 14 and hasa roller 24 atits other 'endthat follows a cam 25 fixedly mounted on the frame 'ofthe machine (FIGURESL 4, '16 and 18'), whereby at the proper time the ram is slid in the slot 19 in the carrier to push the spout out of said slot and through the wall of the container. A tension spring 26 normally holds the roller in contact with the cam 25 and normally influences the lever 22 to retract the pusher into its normal position at the rear end of the slot 19 to permit the spout to be picked up by the carrier at the other end of said slot as best shown in FIGURES 7 and 19.

As above stated, the mount 10 also carries the anvil 13 and as shown (FIGURES 1, 2, 13 and 15), the anvil includes a head 27 of a width slightly less than the width of one of the containers and of a length suflicient to extend into the container in juxtaposition to the container wall that is to receive the spout as best shown in FIG- URES 21 and 24. The head has two elongated V-shaped notches 28 in its lower end to provide clearance for the spout Wings as the spout is inserted (FIGURES 15 and 24) and the head also has depressions 29 to receive and clinch the prongs b of the spout as shown in FIGURES 21 and 22. The anvil head is disposed on one end of a lever 30 which is pivotally mounted on a horizontal axis 31 on the mount (FIGURES 5 and and the other end of said lever has journaled thereon a roller 32 which follows a track 33 having a cam 33' (FIGURES 4 and 5) that is mounted on the main frame so that at the proper time and at the proper position of the corresponding unit P, the anvil will be swung from its normal position above the spout-forming mechanism and the containers (FIGURES 5, 3 and 20, respectively, and broken lines in FIGURE 15) to its spout-inserting position shown at the right hand side of FIGURE 2 and in FIGURES l, 4, 13, 15 and 21. A tension spring 34 normally biases the lever so as to cause the roller 32 to follow the cam and to influence the lever 30 to raise the anvil head into its normal retracted position above the spout-forming mechanism and containers as shown in FIGURE 5.

As hereinabove generally explained, the spout is picked up from the spout-forming mechanism and frictionally held by the spout carrier as the carrier moves over the forming mechanism, but desirably means is provided for forcing the spout into proper position in the carrier, especially when the spout is of the type wherein the straight edges p of the spout wings are disposed at an angle of less than ninety degrees to the plane of the spout body portion as best shown in FIGURES 6, 7 and 10-12. FIGURE 7 shows the carrier and the completed spout at the upper end of the spout blank strip in the relative positions assumed just prior to the severing of the spout from the blank strip with the spout partially inserted into the carrier slot 19 and the carrier moving in the direction indicated by the arrow. Upon closing of the forming dies 1' and i, the cutting edges 1'' and i (FIGURE 6) engage so as to sever the spout from the blank strip, whereupon the severed spout is moved by and with the carrier.

It is necessary that there be clearance between the top surfaces of the spout-forming mechanisms N, O and the lower surface of the spout carrier as shown in FIGURES 6 and 7, and, as hereinbefore indicated, it is also necessary that the spout be firmly frictionally gripped by the walls 19' of the slot 19 in the carrier. As shown, an upwardly inclined resilient plate 35 is secured at one end to each spout-forming mechanism as by screws 36 and has its other end otherwise unsupported so that the carrier and spout will move over said plate and the spout will be pushed upwardly into the carrier by sliding contact of the spout with the plate as best shown by a comparison of FIGURES 7 and 12 in the latter of which the spout is shown fully pushed into the carrier. As the spout is pushed upwardly, the Wings 0 are pressed or sprung toward each other from their normal position shown in FIGURES 8 and 25 into the position shown in FIGURE 26 and the inherent resiliency of the wings causes frictional contact thereof with the walls 19' of the slot 19 such that the spout is yieldingly frictionally held in the carrier.

The spout must also be pushed or tilted rearwardly to compensate for the acute angular relation of the lower edges c' of the wings to the body portion, from a position shown in FIGURE 10 immediately after the spout has been severed from the blank strip to the position shown in FIGURES 11, 6 and 26 where the spout body portion is shown as having been pushed rearwardly and firmly against the ram block 20. One means for so tilting the spout is shown in FIGURES 6, 7 and 10-12 and comprises a wheel 36 rotatably mounted on a horizontal headed pivot stud 38 and having a plurality of fingers 37 that project approximately radially and are curved in the same direction in the plane of the wheel with their free ends pointing toward the spout-forming mechanism and extending upwardly through a slot 39 in the plate 35 and with one of the fingers normally extending above the top surface of the plate as shown in FIGURE 6 so as to be engaged by the oncoming spout as shown in FIGURE 10. Rotation of the wheel under the pushing action of the spout is yieldingly restrained, preferably frictionally, and as shown in FIGURES 6 and 9, the wheel has a plurality of sockets 40, one for each finger, with which coact a spring pressed ball 41 that is mounted in a block 42 rigidly secured to the underside of the plate 35 and in which the headed pivot stud 38 is secured. A compression spring 43 is interposed between the head of the stud 38 and the wheel to normally press the wheel into frictional contact with the block 42 as best shown in FIG- URE 9 and thereby frictionally resist rotation of the wheel; and the ball 41 successively seats in the sockets 40 to cause proper step by step rotation of the wheel. Obviously the resistance of the wheel to the movement of the spout by the carrier causes the spout to be pushed rearwardly in the carrier as shown in FIGURES l0 and 11, and the wheel is rotated in the direction of the arrow by the force of the carrier so as to move the finger engaged by a spout out of the path of movement of the spout and carrier and at the same time move the next finger into position to tilt the next spout as shown in FIGURES 11 and 12.

It will be noted that it is necessary that the container closure flap i must be disposed outside of the container and in a horizontal plane or below it, when the anvil moves into and out of the container, so as not to interfere with the spout-inserting operation; and desirably the mount 10 for the anvil and spout carrier is provided with an arm 45 projecting outwardly therefrom toward the container conveyor and at an elevation slightly higher than the container flap f when the latter is swung outwardly of the container into a horizontal position as shown in FIGURE 1 and by broken lines in FIGURE 13, so that as the mount is slid outwardly to the spout-inserting position, the arm will move into overlying relation to the container flap and thus hold the flap against swinging upwardly during the spout-inserting operation.

It will also be understood that while the spouts herein shown have their wings c flaring away from the body portion and from each other and are inherently resilient so as to be frictionally gripped in the slot 19 of the carrier, the carrier could be formed to otherwise grip or hold the spouts and to hold spouts of different shapes.

While the invention has been shown as embodied in certain structural details, it will be understood by those skilled in the art that this is primarily for the purpose of illustrating the principles of the invention and that many modifications and changes can be made in the construction of a machine within the spirit and scope of the invention.
