Definitions

  • Each carton is moved at high speed with one end panel leading by a carton carrier along a first straight path, then along a curved path through a filling station, and then along a second straight path.
  • the carrier is attached to a drive chain, an the chain is trained around a sprocket to establish the curved path through the filling sta- ⁇ 541 MACHINE FOR FILLING CARTONS tion. Attached to the sprocket and extending radially outward 7 Claims, 5 Drawing Figs.
  • This invention relates to a machine for filling flexible walled canons and more particularly, to a machine in which the cartons to be filled have opposed end panels and opposed side panels and in which the cartons are advanced one at a time by a cari'ier through a filling station to receive a measured amount of product.
  • the primary aim of the present invention is to facilitate filling of the cartons by positively bowing the cartons to widely open positions during their advance toward the filling station and in a manner which enables advance of the cartons at faster speeds than has been possible heretofore and which, at the same time, avoids the danger of contaminating the insides of the carton during the bowing operation.
  • Another object is to position the fingers alongside opposite end panels of the cartons in a novel manner as the cartons are moved toward the filling station.
  • FIG. l is a fragmentary plan view of a carton filling machine embodying the novel features of the present invention.
  • FIG. 2 is an enlarged fragmentary cross section taken substantially along the line 2-2 of FIG. l.
  • FIG. 3 is a perspective view of a bowed carton.
  • FIG. 4 is a fragmentary cross section on a reduced scale taken substantially along the line 4-4 of FIG. 2.
  • FIG. 5 is an enlarged fragmentary elevation taken substantially along the line 5-5 of FIG. 4, the carton being shown in phantom.
  • the invention is embodied in a carton filling machine l0 (FIG. l) operable to dispense measured amounts of material such as ,strawberries and their juice into upright cartons ll (FIGS. l)
  • Each of the cartons ll herein comprises a closed bottom and two opposed, resiliently flexible side panels 14 and l5 (FIG. 3) connected along opposite side margins to two narrow rectangular end panels I6 and 16a.
  • side flaps I7 and 18 and end flaps 19 and 20 projecting upwardly from the panels are folded across the upper ends.
  • the closure flaps are resiliently hinged at 2l to the panels and normally assume upright positions until folded over and sealed closed.
  • the cartons ll are supported and advanced along a first straight path 22 (FIG. l), then along a semicircular path 23 through the filling station l2 and beneath the discharge nozzle 13 and finally along a second straight path 24.
  • the cartons are supported and advanced on an endless carrier comprising a pair of parallel horizontal chains 25 and 26 (FIG. 2) trained around vertically spaced lower and upper sprocket wheels 27 and 28 journaled on a frame 29 and suitably driven at a high rate of speed.
  • the bottoms ofthe cartons slide on a stationary track 30 (FIG.
  • each carton extends around the outside of ⁇ and beneath the chains while the inner side panel l5 and the end panels 16 and 16a of each carton fit into and are carried by two vertically spaced holders 3l (FIGS. l, 2 and 4)-s ⁇ paced equally along and connected to the outer sides of the chains.
  • Each holder is formed with outwardly projecting legs 32 (FIG. l) engaging the end panels and with a web 33 spanning the legs and supporting the inner side panel l5.
  • a curved horizontal rail 34 (FIG. 2) upstands from and is connected to the track and positioned alongside the semicircular portion 23 of the carton path to guide the side panels I4 as the cartons are advanced.
  • the end panels 16 and 16a of each carton 1l are forced toward one another just prior to the filling of the carton thus bowing out the side panel I4 to open the carton widely to receive a large amount of product in a short time interval and to receive product chunks larger than the unbowed thickness of the carton.
  • pairs of fingers 36 (FIG. 4) are suspended beneath and pivotally supported by the upper sprocket wheel 28 with the fingers of each pair spaced apart and positionable on opposite sides of the end panels of a carton. The fingers of each pair may be pivoted toward one another to engage the end panels of the carton thus forcing the end panels toward one another and bowing out the side panel 14.
  • each finger 36 is one portion of an L-shaped squeezer 37 (FIG. 4) which preferably is pivotally mounted to turn about a vertical axis by a pin 33 at the corner of the L on the horizontal leg 39 of an L-shaped support 40 (FIG. 2) whose other leg is vertically extending and connected by a pair of bolts 4l to the underside of the upper sprocket wheel 28.
  • the other portion of each squeezer is formed as a pivot arm 42, (FIG. 4) which extends at a right angle from the finger.
  • the fingers of each pair of squeezers are spaced apart a greater distance than the distance between the end panels 16 and 16a of the cartons ll. From FIG. 4, it will be observed that the fingers extend radially outwardly from the pivot pins 38 a distance great enough that the free ends of the fingers can project beyond the outer margins of the cartons.
  • the squeezers 37 are paired with the pivot arm 42 of each pair extending toward one another and with the fingers 36 extending generally parallel to one another in their normal positions as exemplified by the fingers in FIG. l which are not between the cartons. Because the upper sprocket wheel 28 is driven by the chain 26, the pairs of the squeezers are moved along a circular path, half of which is coextensive with the semicircular path 23 of the cartons ll, and the squeezers are moved along the path in timed relation with the advance of the cartons. At the point at which the first straight path 22 becomes generally tangent to the circular path of the squeezers, the fingers 36 of each pair of squeezers move into registry with an advancing carton.
  • each pair of squeezers 37 can be swung in unison to swing the free ends of the fingers 36 toward one another and into gagement with the end panels i6 and 16a of the carton disposed between the fingers.
  • the outer end portion of a link M (FIG. 4) is pivotally connected to each pivot arm.
  • the inner end portions of the pivot rods for each pair of squeezers are pivotally joined to one another and to the outer end portion of a cam rod 45 by a pin 45a, and the cam rod extends radially inwardly toward the axis of rotation of the upper sprocket wheel 28.
  • a roller 46 (FIG.
  • each cam rod rotatably mounted on the inner end portion of each cam rod extends upwardly therefrom and is seated in a cam track 47 (FIGS. ll, 2 and d).
  • the cam track is formed as a recess in a solid member 4d (FIG. 2) rigidly connected to the frame 29.
  • the cam track is, as seen in FIG. ll, generally eccentric and is nearer the axis of rotation of the upper sprocket wheel 28 in the area of the filling station i2.
  • each cam rod 45 is slidably mounted through and suspended from the upper sprocket wheel 28 by a guide 5B.
  • the guide is formed in this instance by a rectangular block 52 (FIG. 5) connected at its upper surface to the underside of the upper sprocket wheel 28 by four bolts 54 (FIGS. l and 5), and a recess 55 (FIG. 5) just slightly larger than the cam rod is formed in the bottom of the rectangular block.
  • a cover plate 56 is connected by bolts 57 to the underside of the rectangular block.
  • openings 57a (FIGS. l and 2) are formed in the upper sprocket wheel above each cam rod. Lubricant can be ejected into the recess 55 through a lubrication port 58 (FIG. 2) formed in the block 52.
  • the squeezers 37 are advantageously mounted on the I.'y shaped supports 40 so that one pivot pin 38 can be used to mount two squeezers.
  • One squeezer of one pair is mounted either under or over the adjacent squeezer of the adjacent pair of squeezers, and the pivot pin extends through both squeezers to pivotally connect them to the support.
  • the squeezers of the same pair are mounted on different levels. That is, one squeezer is the upper of two on one pivot pin and the other squeezer is the lower of two on the adjacent pivot pin.
  • a machine for filling cartons having opposed side panels, opposed end panels and open upper ends
  • a frame operable to support a succession of spaced cartons and advance the same open end up along a first predetermined path through a filling station with one of the end panels of each carton forming the leading end of the carton
  • a second carrier on said frame, at least one pair of opposed fingers each mounted on said second carrier to pivot about a vertical axis, said second carrier being operable to move said fingers along a second path coextensive with said first path from a point ahead of the filling station to a point beyond the filling station in timed relation with the advance of the cartons, and means operable when said paths are coextensive to pivot the fingers toward one another and into engagement with the end panels of one of the cartons to press the end panels toward one another and thereby bow at least one of said side panels away from the other side panel to spread the carton for receiving a charge of product at the filling station.
  • a frame a first carrier on said frame operable to support a succession of spaced canons and advance the same open end up along a first predetermined path through a filling station with one of the end panels of each carton forming the leading end of the carton
  • a second carrier on said frame, a number of pairs of opposed fingers supported on said second carrier with each finger being mounted to pivot about a vertical axis, the fingers of each pair normally being spaced apart a distance greater than the spacing between the end panels of each carton
  • said second carrier being operable to move said pairs of fingers in timed relation with the advance of the cartons along a second path which becomes coextensive with said first path from a point ahead of the filling station and which remains coextensive with said first path to a point beyond the filling station and being operable to move successive pairs of tingers into registry with successive cartons as said pairs of fingers and said cartons pass said point at which said paths become
  • a frame operable to support a succession of spaced cartons and advance the same open end up along a first predetermined path through a filling station with one of the end panels of each carton forming the leading end of the carton, said first path being substantially straight to a first point ahead of the filling station, arcuate to a second point beyond the filling station and thereafter straight, a second carrier on said frame, a number of pairs of opposed fingers supported on and spaced along said second carrier with each finger being mounted to pivot about a vertical axis, said fingers of each pair normally being spaced apart a distance greater than the spacing between the end panels of each carton, said second carrier being operable to move said fingers in timed relation with the advance of the cartons along a circular path having a portion coextensive with said arcuate portion of said first path and being operable to move successive pairs of fingers into registry with successive cartons as said pairs
  • said second carrier is a circular member mounted to rotate about a vertical axis, said pairs of fingers being angularly spaced about the periphery of said member, and further including a pivot member mounting one finger of each pair and the adjacent finger of the adjacent pair to pivot about a common vertical axis.
  • said means to pivot the fingers of each pair includes an actuator common to each pair and pivotally connected to each of said fingers.
