Definitions

  • This invention relates generally to methods of and apparatus for making packages, and more particularly a method of and apparatus for making packages of the type comprising a roll or rolls of paper, such as a paper towel roll or rolls of toilet tissue in flexible sheet wrapping material such as heat-sealable plastic film.
  • These packages are completed by folding each projecting end of the wrapper over the ends of the rolls to form four closure flaps overlying each end, a first flap constituting a first side flap, which may be referred to as the top flap, a second flap constituting a first end flap, a third flap constituting a second end flap, and a fourth flap constituting a second side flap which may be referred to as the bottom flap, the four flaps at each end of the rolls being heat-sealed together to complete their Formation as end closures for the package.
  • This invention has for its object the provision of a method of and apparatus for efficiently folding over the stated second end flap for formation of neat end closures in a high-speed operation and capable of handling packages of rolls of different sizes and different numbers of rolls.
  • the method of this invention involves continuously feeding packages forward one after another in a predetermined path at a predetermined speed with the packages extending transversely with respect to the direction of feed and with a trailing portion of the extending end of the wrapper extending laterally outwardly at one side of said path, and with the packages spaced at intervals along said path, and, as the packages are so fed forward, bringing a flexible folding member into engagement with the trailing side of said trailing portion of the extending end of the wrapper of each package, and moving said flexible folding member forward in the direction of movement of the package at a higher speed than the speed of the package to fold over said trailing portion or said end of the product to form said second end flap, and then moving said flexible folding member laterally outwardly away from said folder-over second end flap.
  • apparatus of this invention involves means for continuously feeding packages forward one after another in a predetermined path at a predetermined speed with the packages extending transversely with respect to the direction of feed and with a trailing portion of the extending end of the wrapper extending laterally outwardly at one side of said path, and with the packages spaced at intervals along said path, a flexible folding member for folding over said trailing portion on said end of the product, and means operable as the packages are so fed forward for bringing the flexible folding member into engagement with the trailing side of said trailing portion of the extending end of the wrapper of each package, and moving said flexible folding member forward in the direction of movement of the package at a higher speed than the speed of the package to fold over said trailing portion on said end of the product to form said second end flap, and then moving said flexible folding member laterally outwardly away from said folded-over second end flap.
  • a package comprising a unit of product indicated in its entirety at 1 which is illustrated as a set of two rolls each designated 3 of toilet tissue disposed side-by-side with their axes parallel, and a wrapper 13 wrapped around the product (the two rolls).
  • the wrapper is wider than the length of each roll measured from end-to-end of the roll and initially extends outwardly beyond each end 3e of the unit constituted by the two-roll set of rolls.
  • the wrapping is completed by folding over each extending end E of the wrapper on the respective end 3e of the unit as packages are continuously fed forward one after another in a predetermined path at a predetermined speed with the packages extending transversely with respect to the direction of feed to form four closure flaps F1-F4, namely a first side flap F1 at the top, a first end flap F2 at one end constituting the leading end of the wrapper, a second end flap F3 at the other end (the trailing end) of the wrapper and a second side flap F4 at the bottom.
  • top side flap, the leading end flap and the bottom side flap are readily folded over as, for example, by means of stationary plans in conventional manner, portions of the projecting ends of the wrapper engaging the plows as the package is fed forward for folding them over.
  • the top side flap may be blown down by a blast of air.
  • the formation of the trailing end flap F3 presents a problem, however, on account of the forward movement of the package, and this invention involves a method of and apparatus for folding over the trailing end flap for formation of neat end closures in a high speed operation (e.g. 250 packages per minute) capable of handling packages of rolls and different numbers and arrangements of rolls (e.g. the typical single-roll packs, two-roll packs and three-roll packs).
  • Packages P each having wrapper 13 with its extending ends E may be formed at relatively high speed (e.g. 250 packages per minute) by apparatus such as indicated in its entirety at A in Fig. 6, which apparatus is the same as that disclosed in the above-noted U.S. Patent 4,430,844 of Robert C. James, issued February 14, 1984 to Hayssen Manufacturing Company of Sheboygan, Wisconsin, this James patent being incorporated herein by reference.
  • Fig. 6 corresponds to Fig. 1 of said patent, showing web 5 of plastic film, e.g.
  • polyethylene being pulled from supply roll 7, perforated as indicated at 11 at wrapper length intervals by means 9, formed into tubing T around two-roll units 1 fed forward by means 15, the units being spaced lengthwise of the tubing with the lines of perforations in the spaces between the units, and pulling means 29 for pulling the tubing apart at the lines of perforations to form the packages P.
  • Each package P as formed by the apparatus A of Fig. 6 (the apparatus ot U.S. Patent 4,430,844) is delivered to a flight conveyor generally designated 31 which functions to feed the packages forward one after another in a predetermined path (a horizontal path) with the packages extending transversely with respect to the direction of feed and with the free ends E of the wrapper 13 extending laterally outwardly from the two-roll units 1 therein at opposite sides of said path.
  • a flight conveyor generally designated 31 which functions to feed the packages forward one after another in a predetermined path (a horizontal path) with the packages extending transversely with respect to the direction of feed and with the free ends E of the wrapper 13 extending laterally outwardly from the two-roll units 1 therein at opposite sides of said path.
  • the conveyor 31 comprises a slotted table 33 along which packages P are pushed by pushers or flights 35 on an endless chain 37 trained around a rear end sprocket 39 and a forward end sprocket 41 with an upper forward-moving reach 37a of the chain 37 just under the table and a lower return reach 37b below the upper reach.
  • the pushers or flights 35 are mounted on arms 43 which, along the upper reach of the chain, extend up through the slot 45 in the table 33.
  • the pushers act to push packages P forward along the table, and are spaced a distance greater than the width W of a package.
  • the chain is driven for forward movement of its upper reach generally at a predetermined constant speed by drive means such as indicated at 47 and its operation is so timed in relation to the delivery of packages P by the pulling means 29 of apparatus A that each package is delivered onto the table adjacent the rearward end of the table in front of an oncoming pusher or flight 35, the flights acting to push the packages forward one after another along the table with the packages spaced at intervals corresponding to the flight spacing D, with the wrapper ends E extending laterally outwardly from the roll unit ends 3e toward opposite sides of the table.
  • the wrapper ends E first pass through a station A (Fig. 6) where the top flaps F1 are folded over and down at both ends of the package by suitable conventional means (not shown) such as air blast means. They then pass through a station B (Fig. 7) where the leading end flaps F2 (the first end flaps) are folded back at both ends of the package by suitable conventional means (not shown) such as plows, one at each side of the table. They then pass through a station C (Fig.
  • the aforesaid folding or tucking means 49 comprises a left-hand unit 49L for folding or tucking the second (trailing) end flap F3 over on the left end of the package, i.e. folding or tucking it over to lie flat against the previously folded-over top flap F1 on the left end of the package, and a right-hand unit 49R for folding or tucking the second (trailing) end flap F3 over on the right end of the package, i.e. or folding or tucking it over to lie flat against the previously folded over top flap F1 at the right end of the package.
  • Left-hand and right-hand are as viewed in the direction of feed of the packages.
  • the left-hand and right-hand folding or tucking units 49L, 49R are essentially identical (being opposite hand versions of one another), each comprising an endless chain conveyor generally designated 51 at the respective side (the left-hand side or the right-hand side as the case may be) of the path along which the packages P are fed forward by the package conveyor 31 having a forward travelling linear (straight) inner reach 51a generally parallel to said path opposed to the respective package end and a rearward travelling linear outer return reach 51b.
  • At 51c is indicated the forward end reach of the conveyor 51 where it moves around in a semicircular path from the inner reach to the outer return reach
  • at 51d is indicated the rearward end reach of the conveyor 51 where it moves around in a semicircular path from the outer to the inner reach.
  • the endless chain conveyor 51 is constantly driven at a speed somewhat higher than the speed at which the packages p are fed forward by the conveyor 31, and carries a flexible folding member or tucker 53 movable forward at said higher speed along with the inner reach 51a of conveyor 51 which comes into engagement with the trailing side 55 of the trailing portion 57 of the respective end E of the wrapper of each package, moves linearly forward relative to the end of the package to fold over or tuck over said trailing portion of the end of the wrapper on the respective end of the set of rolls in the wrapper to form the stated second end flap F3, and then moves laterally outwardly away from the folded-over second end flap.
  • the endless conveyor 51 of each of the units 49L, 49R comprises a relatively short beam 59 mounted in position extending horizontally at the respective side (left or right) of the path, more precisely at a level somewhat above the level of the path, along which the packages P are fed forward by the conveyor 31.
  • Each beam 59 has a vertical bearing 61 at one end thereof, namely, its trailing or rearward end in respect to the direction of travel of the packages P and a vertical bearing 63 at its other end, which is its leading or forward end in respect to the direction of travel of the packages.
  • the beam 59 of the left-hand unit 49L is mounted as shown in Fig. 9 on a pedestal 65 at the left side and the beam 59 of the right-hand unit 45R is mounted on a pedestal 67 at the right side.
  • Shafts 69 and 71 are journalled in the bearings 61 and 63, respectively, each shaft having a sprocket 73 at its upper end and a sprocket 75 at its lower end.
  • a chain 77 is trained around the upper sprockets 73 and a chain 79 is trained around the lower sprockets 75.
  • the upper and lower sprockets are of equal diameter, and thus the chains have inner reaches travelling one above the other in a vertical plane delineating the inside reach 51a of the endless conveyor 51 and outer reaches travelling one above the other in a vertical plane constituting the outer return reach 51b of the endless conveyor 51.
  • Each of the chains comprises a series of links 81a and 81b pivotally interconnected by tubular pivot pins 83. Backups for the inner and outer reaches of the chains are indicated at 85 and 87, respectively.
  • the chains 77, 79 are driven in timed relation to the chain 37 of the package conveyor 31 by a drive such as indicated at 80 in Figs. 6 and 8 connected to shaft 71.
  • each of the aforesaid flexible folding or tucking units 49L, 49R includes a single flexible folding member or tucker 53 constituted by a brush adapted to brush or "wipe" over the respective second (rear) end flap F3, this brush comprising a rectangular back 93 having a pattern of bristles 95 on one face thereof, which pattern may be as shown in Fig. 10.
  • the brush 53 is carried by means generally designated 97 removably pinned in the upper and lower chains 77, 79 for movement of the brush with the chains and for movement of the brush relative to the chains with a special motion to be described.
  • the carrier means 97 for the brush comprises a pair of brackets 101 and 103 extending vertically between the upper chain 77 and the lower chain 77, the brackets being spaced from one another along the length of the chains and being movable with the chains in the direction of chain movement.
  • the first bracket 101 which is the leading bracket of the two brackets in relation to the direction of movement of the chains, comprises a bar 105 which extends vertically between the chains having a head 107 projecting laterally at its upper end and a foot 109 projecting laterally at its lower end.
  • Two pins each designated 111 are vertically slidable in holes 113 in the head between a raised extended position entered in two adjacent tubular pins 83 of the upper chain 77 for the removable attachment of the bracket at its upper end to the upper chain
  • two pins each designated 115 are vertically slidable in holes 117 in the foot between a lower extended position entered in two adjacent tubular pins 83 of the lower chain for the removable attachment of the bracket at its lower end to the lower chain 79.
  • the upper pins 111 extend up from a finger tab 119 by means of which they may be moved down to a retracted position withdrawn from the tubular chain pins 83 of the upper chain against the upward bias of a spring 121 (which biases the tab upwardly toward the bottom of the head 107.
  • the lower pins 115 extend down from a finger tab 123 by means of which they may be moved up to a retracted position withdrawn from the tubular chain pins 83 of the lower chain against the downward bias of a spring 124 (which biases the tab 123 downwardly toward the top of the foot).
  • the second bracket 103 which is the trailing bracket of the two brackets in relation to the direction of movement of the chains, comprises a bar 125 which extends vertically between the chains having a head 127 projecting laterally at its upper end and a foot 129 projecting laterally at its lower end.
  • Two pins each designated 131 are vertically slidable in holes 133 in the head between a raised extended position entered in two adjacent tubular pins 83 of the upper chain 77 for the removable attachment of the bracket 103 at its upper end to the upper chain
  • two pins each designated 135 are vertically slidable in holes 137 in the foot between a lower extended position entered in two adjacent tubular pins 83 of the lower chain 79 for the removable attachment of the bracket 103 at its lower end to the lower chain.
  • the upper pins 131 extend up from a finger tab 139 by means of which they may be moved down to a retracted position withdrawn from the tubular chain pins 83 against the upward bias of a spring 141 (which biases the tab upwardly toward the bottom of the head 127.
  • the lower pins 135 extend down from a finger tab 143 by means of which they may be moved up to a retracted position withdrawn from the tubular chain pins 83 of the lower chain against the downward bias of a spring 144 (which biases the tab 143 downwardly toward the top for the foot 129.
  • a shaft 147 journalled in the head 107 and foot 109 of the stated first or leading bracket 101 extends vertically downward from the bracket into a hole 149 in the back of 93 the brush 53 adjacent the leading end of the brush (the leading end in relation to the movement of the brush with the chains 77, 79) for pivoting the brush for swinging movement about the vertical axis of the shaft.
  • a crank arm 151 in the form of a yoke is pivotally mounted as indicated at 153 on a block 155 on the bar 125 of the stated second or trailing bracket 103 for swinging movement of the yoke relative to the bracket on a vertical axis.
  • a shaft 157 journalled at its upper end in the yoke 151 as indicated at 159 extends vertically downward from the yoke into a hole 161 in the back of the brush adjacent the trailing end of the brush.
  • the lower ends of the shafts 147 and 157 are secured as by set screws 162 in the back of the brush, the upper end of shaft 147 being rotatable in the bracket 101, the upper end of the shaft 157 being rotatable in the yoke 151 (which is pivoted at 153 on the bracket 153).
  • the brush 53 is movable by and with the chains 77 and 79 in an endless path having straight inner and outer reaches parallel to the straight inner and outer reaches 51a, 51b of the chains.
  • the arrangement is such that as the brush travels along the inner and outer reaches, it is held by the shafts 147 and 157 in a vertical position with its ylane parallel to the inner and outer reaches, the yoke 151 occupying the position relative to bracket 103 in which it appears in Fig. 14 extending outwardly generally at right angles relative to the plane of the inner reach of the chains 77, 79.
  • the arrangement is also such that the brush is adapted for swinging movement relative to the chains about the vertical pivot axis of the shaft 147 in the course of its travel with the chains 77, 79 as they travel around the sprockets 73, 75.
  • chain 37 of conveyor 31 is continuously driven at a predetermined speed so related to the delivery of packages P by pulling means 29 of apparatus A (see also the aforesaid James U.S. Patent 4,430,844), and in such timed relation to said delivery that each package issuing from apparatus A is delivered onto the table 33 in front of an oncoming flight 35 of conveyor 31.
  • Each package is then continuously fed forward by said flight along the table in a predetermined horizontal path at the predetermined speed of the flight.
  • the flights may be changed to accommodate packages of Different lengths.
  • the packaqes so fed forward extend transversely with respect to the direction of feed, with the free ends E of the wrapper 13 of each package extending laterally outwardly from the product unit 1 therein at opposite sides of the path.
  • each package P As each package P is fed forward, it first passes through station A where top flaps F1 are folded over and down at both ends of the package and then through station B where the leading flaps F2 are folded back at both ends of the package, as previously described. The package then passes between the left-hand and right-hand folding or tucking units 49L, 49R at station C.
  • the endless chain conveyor 51 of each of units 49L, 49R is continuously driven with chains 77 and 79 of the conveyor 51 of each unit 49L, 49R travelling at a speed higher than the speed at which the packages P are fed forward along the table 33.
  • Travel of the brushes 53 of units 49L, 49R is so phased with respect to the travel of packages as the packages pass between units 49L, 49R that the brushes come around the rearward or trailing end 51d of the endless conveyors 51 of units 49L, 49R, and into the forward-traveling inner reaches 51a of their paths of travel after a package has progressed forward beyond the rearward or trailing ends of units 49L, 49R.
  • the bristles of the brushes come into engagement with the trailing side 55 of the trailing portion 57 of each end of the wrapper 13 (which already has flaps F1 and F2 folded over), flex back as the brushes move linearly forward faster than the package, and fold or tuck over the trailing portion 57 of the ends of the wrapper on the ends of the set of rolls in the wrapper to form the rear end flaps F3.
  • the brushes 53 in effect, wipe over the rear end flaps F3, the wiping action occuring as the package is moving forward by reason of the brushes moving forward at a higher speed than the package.
  • bracket 101 for each chain starts travelling around in the forward end 51c of its path of travel with the chains around the forward sprockets 73,75.
  • This change in direction from linear (straight-line) forward travel to arcuate outward travel results in each brush swinging relative to its respective set of chains 77, 79 about the vertical axis of the respective shaft 147 (carried by bracket 101) with accompanying swinging of the crank arm or yoke 51 to a position such as illustrated at the left upper portion of Fig. 8 and in Fig. 9.
  • the apparatus is very forgiving of variations in the dimension of packages transversely of the conveyor (i.e. what may be referred to as the package length), and is adapted to allow the brushes to remain in contact with the folded-over flaps F3 right up to the point of overlapping with the plow 163.
  • the spacing of the flights 35 of the conveyor may change as, for example, by removing every other flight to double the flight spacing so as to accommodate the higher package width.
  • the apparatus may also be used to package single rolls of paper toweling, for example, adjusting the lateral spacing of the left and right-hand units 49L, 49R to accommodate the greater length of the paper towel package in which case it may be desirable to mount a second brush 53 on each brush conveyor 51 spaced halfway around the conveyor from the one brush 53.
  • addition of the second brush may be easily and quicky effected simply by retracting the pins 111 and 115 of bracket 101 and the pins 131 and 135 of bracket 103, positioning the bracket between the upper and lower chains, and then releasing the pins to slide into respective tubular chain pins 83. And with the retractable pin mounting of the brackets, the brush carriers 97 are readily removable for repair and/or replacement.
