Definitions

  • the containers are moved in a straight linear path in spaced apart relation on a conveyor with the wall of the container in which the spout is inserted approximately perpendicular to the paths of the container and the spout-inserting unit.
  • the containers are mounted on a rotary conveyor on arms that are radially disposed on a vertical shaft which is rotated to move the containers in an arcuate path with the walls to receive the spouts disposed radially to said arcuate path, and a primary object of the present invention is to provide a machine that shall be simple, relatively inexpensive, reliable and durable, for attaching spouts to containers handled by such a rotary conveyor that is commonly used in package forming and filling machines.
  • Another object is to provide a machine of this character with novel and improved means for mounting and moving the spout-inserting units in an endless course a portion of which is arcuate and approximately concentric with said rotary conveyor, whereby the spouts can be accurately and rapidly attached to or inserted into the walls of the containers while said containers are moved in said arcuate path and said spout-inserting units are moved along their said course of movement.
  • Each spout-inserting unit includes a spout carrier which picks up the spout at the spout-feeding station and carries it to the spout-inserting station, and another object of the invention is to provide novel and improved means for insuring that the spout shall be firmly seated in the carrier to prevent accidental dislodging of the spouts during movement of said unit.
  • FIGURE 1 is a schematic top plan view of a machine embodying the invention, with portions broken away and other portions omitted for clearness in illustration;
  • FIGURE 1B is an enlarged fragmentary elevation of one of the container conveyor arms and a container mounted thereon;
  • FIGURE 3 is an enlarged combined transverse vertical sectional view and side elevation taken approximately on the plane of the line 3-3 of FIGURE 1;
  • FIGURE 4 is a front elevation of the parts shown in FIGURE 3 and viewed approximately from the plane of the line 44;
  • FIGURE 5 is an enlarged fragmentary partial plan and partial horizontal sectional view approximately on the plane of the line 5-5 of FIGURE 2;
  • FIGURE 6 is an enlarged fragmentary vertical sectional view approximately on the line 6-6 of FIGURE 1, showing a completed spout at the end of the spout :blank strip about to be severed from the strip in position to be picked up by the spout carrier of the spout-inserting unit;
  • FIGURE 7 is a similar view showing the completed spout severed from the spout blank strip and the spout forming dies opened preliminary to feeding of the spout blank strip to locate the next completed spout in position to be picked up by another carrier, and showing a spouttipping mechanism in normal position;
  • FIGURE 8 is a similar view showing the initial operation of spout-tipping mechanism for pushing the spout into the carrier;
  • FIGURE 9 is a similar view showing the spout seated in the carrier.
  • FIGURE 10 is a fragmentary vertical sectional View approximately on the plane of the line 10I0 of FIG- URE 1, showing the carrier, the anvil and the carton in their relative positions immediately prior to the insertion of the spout into the container wall;
  • FIGURE 11 is a similar view showing the spout inserted into the wall
  • FIGURE 12 is a fragmentary horizontal sectional view approximately on the plane of the line 12-42 of FIG- URE l1;
  • FIGURE 13 is an end elevation of the spout-tipping mechanism and the spout carrier from approximately the plane of the line 1313 of FIGURE '7.
  • the spout herein contemplated is shown as comprising a body portion a, prongs b on the body portion to penetrate and to be clinched upon the upper 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.
  • 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 also the flanges are angularly related to each other in the same way in which the longitudinal edges of the body portion a from which the wings project are inclined to each other.
  • the reference character A generally designates a rotary conveyor for the container B which are shown as comprising rectangular boxes having the usual side and end walls d and a, respectively, side flaps f and end flaps g.
  • Any suitable means may be used for mounting the containers on the conveyor but for the purpose of illustration the containers are shown as disposed on arms C that are carried and project radially from a shaft D that is journaled in a suitable stationary support E to rotate about a vertical axis.
  • Each arm has a main plate F secured to its outer end in a vertical plane on which are mounted side jaws G and H between which is gripped one of the containers as best shown in FIGURES 1 and 1B.
  • the jaws are carried by the respective slide plates I and K which are slidably mounted on the plate F by pin and slot connections L.
  • the two slides are pivotally connected together by a lever M that is pivotally mounted at O on the plate F and has a hand grip N at one end so that the two plates will move simultaneously in opposite directions upon swinging of the lever.
  • the plates and corresponding jaws are normally biased in one direction by a spring P to grip a container between the jaws, and the jaws may be separated to insert and remove a container into and from the jaws by manual operation of the lever M.
  • the containers with their upper ends open, are set into the jaws at a desired point in the path of rotation of the jaws, and the carrier is rotated by any suitable means so that the containers are caused to move through an arcuate path to a spout-inserting station with the end wall e of each container that is to receive the spout disposed approximately radially to that arcuate path.
  • the conveyor may be driven by any suitable means but schematically there is shown a pulley and cross belt drive Q between the shaft D and a countershaft R which is driven as hereinafter described.
  • a spout-carrying, spoutinserting and anvil mechanism generally designated U which receives finished spouts X from a spout-forming and feeding mechanism V that may be of any suitable construction, preferably of the general type shown in Patents No. 2,892,438 or No. 3,025,813.
  • the unit W of which the carrier forms a part moves with the spout therein to the spout-inserting station where the carrier is projected into juxtaposition to the outer side of the end wall e of a container B that is being conveyed through the spout-inserting station, and the anvil 3 is moved inwardly of the container through the open upper end thereof in juxtaposition to the inside of the wall of the container as shown in FIGURES 1, 10, 11 and 12, whereupon the ram 2 is actuated to force the flanges c of the spout through the container wall as shown in FIGURES 11 and 12 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 the path of the containers, it being understood that the unit W moves continuously synchronously with the container conveyor and in the portion of its course
  • the spouts are formed and projected into the path of movement of the spout carriers in timed relation to movement of the latter, the spout blank being shown as fed step-by-step by a mechanism known and generally designated k that is actuated by a cam m on a drive shaft 1 that also has a cam n thereon which actuates the dies.
  • One die i has a cutting edge that cooperates with a cutting edge j on the other die for severing the spout from the blank strip.
  • the spout-forming mechanism is driven through a chain and sprocket connection Y by a drive shaft T which is journaled in the main frame I and has a driving connection S with the countershaft R from which is driven the container conveyor A.
  • the main drive shaft T is driven by any suitable source of power, and the units W are moved by said shaft through the instrumentality of upper and lower chains T and T" that pass around sprockets U and U" and V and V" on the shaft T and on a counter shaft R, respectively, to which chains the units W are connected at equi-distantly spaced points along the lengths of the chains.
  • each unit comprises a support element 5 in the form of a rectangular plate mounted in upper and lower tracks on the main frame.
  • rollers 6 and 7 roll on the respective horizontal track surfaces 8 and 9 which are vertically spaced apart in opposed relation to each other, the rollers being journaled on studs 12 secured in mounting brackets one of which is separably secured to the rear side of the plate at each of the upper and lower ends of the plate by cap screws 11, with the rollers 6 and the rollers 7 spaced apart longitudinally of the support element and extending through arcuate recesses 13 in the upper and lower edges of the plate, respectively.
  • Each support element or plate 5 is connected to the upper and lower chains T and T" adjacent the front or leading end of the plate.
  • a connector block 19 is pivotally connected to each pin 16 between the rollers 14 and 15 and the block is connected to the corresponding upper or lower chain by connector links 20 that are riveted to the connector block at 21 and the links of the chain at 22.
  • These connections are shown in FIGURE 5 and fragmentarily and schematically in FIGURE 1 where the connector links are omitted.
  • Each connector block has a lug 23 projecting from its trailing edge and adapted to simply abut the chain to limit pivotal movement of the connector block relative to the chain during the driving of the support elements.
  • An abutment block 24 is pivotally connected to the pin 16 of the set of rollers 14', 15' adjacent the rear or trailing end of the support element, the block 24 simply abutting the chain to limit swinging of the support element about the axis of the roller pivot pin 16 while driving forces are being applied to the chains and support elements.
  • the support elements may move through or over the curved portion of the chains and tracks with -a minimum of strains on any of the parts, the rollers being free to adjust themselves to the curvature of the tracks without imposing any excessive strains on the pivot pins 16, 16 or on the chains, and at the same time the support elements are firmly guided and held against excessive vibrations in the tracks.
  • rigid strut-spacer elements or plates 25 are mounted in the tracks and connected to the chains at spaced points along the length of the chains, preferably between adjacent support elements 5.
  • Each strut-spacer element has two sets 26 and 27 of rollers, corresponding to the sets of rollers 14, 15 and 14 and 15, respectively, journaled on a mounting bracket 28 like the bracket 10 and secured to the strutspacer element in the same manner that the bracket 10 is secured to the support element 5.
  • each strut-spacer element is connected to the chains T and T as indicated at 29 in identically the same manner in which the support element 5 is connected to the chains through the connector blocks 19, etc.; and the trailing end of the strut-spacer element has pivotally connected thereto abutment blocks 30 like the abutment block 24 on the support element 5. Rollers like 6, 7 are included.
  • the chains are constrained to move absolutely synchronously and with a minimum of possibility of looseness and slapping during the driving operation.
  • the manner of mounting and driving of the support elements insures that they shall be accurately moved along their course of movement and particularly the arcuate portion of the course that is approximately concentric with the path of movement of the containers.
  • Each support plate 5 has an opening therethrough in which is mounted a split tubular guide bracket 31 wherein is horizontally slidable a U-shaped mount 32 which carries the spout carrier 1, the ram or spout pusher 2 and the anvil 3.
  • the spout-forming and feeding mechanisms V are mounted on the main frame adjacent the straight portion of the lower track, and as the units W pass along said straight track portions, the spout carrier first is positioned so as to pick up the completed spout at the upper end of the spout blank strip (FIGURES 1 and 6), and the anvil is first and normally held in a position to clear the spout and the containers as shown by broken lines in FIGURE 3.
  • the mount 32 is actuated to move the carrier, ram and anvil transversely of the path of movement of the container so that the spout carrier of each unit is projected between two adjacent containers in juxtaposition to the outside of one wall of one container, and the corresponding anvil is at the same time projected into a position above the open end of the container and at the opposite side of said wall, whereupon the anvil is swung downwardly into the container close to said wall as shown in FIG- URE 10; and immediately thereafter the spout pusher or ram is actuated to push the spout from the cam'er through said container wall and cause a clinching of the spout prongs on the container wall as shown in FIGURES 11 and 12.
  • the anvil is withdrawn from the container, the ram is retracted to its original position, the mount is actuated to return the carrier, the ram and the anvil to their first-mentioned normal positions and the whole unit continues in its course of movement to the spoutforming and feeding mechanisms to pick up the next spout.
  • the mount is shown as actuated in the manner above described by a roller 33 journaled on the mount and running in a cam track 34 that is secured on the frame sup ported by stanchion plates 35 on the main frame of the machine.
  • This track 34 has an arcuate portion 34' concentric with the path of the container at the spout inserting station, and has a portion 34-" at each end of the arcuate portion to position the mount so that it cannot crush the container as the unit approaches and leaves the arcuate portion.
  • the track also has a straight portion 34 along which the mount and carrier are positioned to pick up a spout.
  • the anvil is carried by a lever 36 pivotally mounted between its ends at 37 on the mount and is actuated by a roller 38 on one end of the lever which follows a cam track 39 also mounted on the stanchion castings 35. Adjacent the spout-inserting station, the cam track 39 has a box cam portion 39 by which the lever 36 is actuated in both directions, while the other portion of the cam track holds the lever in its normal position as shown in FIG- URE 2 and by broken lines in FIGURE 3.
  • the ram is slidably mounted in a slot 40 in the carrier the cross section of which approximately corresponds to the shape of the spout as shown for example in FIGURES 3, 12 and 13.
  • the ram is actuated by a lever 41 pivotally connected intermediate its ends at 42 to the mount 32 and pivotally connected at one end 43 to the ram.
  • the lever has a follower roller 44 that rides over a cam block 45 pivotally mounted at 46 .on a hanger bracket 35' on the stanchion castings 35 adjacent the spout-inserting station.
  • the cam 45 is normally biased by a spring 47 into the path of the roller as shown by broken lines in FIGURE 12, and normally the ram is retracted as shown in FIGURE 10 and FIGURE 12.
  • the roller 44 strikes the cam block 45 and the lever is swung from the broken line position shown in solid lines in FIGURE 12 and in FIGURE 11 so as to push the spout from the carrier slot 40 through the container wall, the roller being guided by a cam track 45' in its travel to and from the cam block to hold the ram in proper position in the carrier.
  • the wings of the spout pass into clearance slots 48 in the anvil, shown in FIGURES l1 and 12, and the prongs are clinched by the pressure between the anvil and the ram to secure the spouts to the container wall.
  • the cam block 45 is swung against the resistance of the spring 47 into the solid line position shown in FIGURE 12 and as the roller 44 moves with the carrier, the action of the spring 47 on the block 45 urges the roller and lever into the broken line position shown in FIGURE 12 and simultaneously retracts the ram into its normal position shown in FIGURE 10.
  • the invention contemplates a spout-tipping mechanism and a seat for the spout in the carrier as shown in FIGURES 6-9 and 13.
  • a spring strip 49 is secured to the ram by for example a screw 50 and has one portion extending along the bottom of the ram and projecting from the front thereof as indicated at 51 to form a seat for the spout, While another portion of the spring extends along the top of the ram and has one end projecting beyond the front of the ram to form a spring detent finger as indicated at 52.
  • a tipping mechanism is mounted on a part of the spout-feeding mechanism or the frame I and comprises a tipping finger 53 rigidly connected to a gear '54 which is journaled on a stud shaft 55 secured in a bracket 56 that is fastened on the spout feeding mechanism or some part of the machine frame.
