Definitions

  • ABSTRACT Arrays of articles are stacked one on top of another in a U-shaped shroud structure which includes vacuum means to retain the upper array while the lower array of articles is positioned therebeneath.
  • a carton blank is simultaneously fed from a stack to a position over the pocket of an intermittently operated conveyor.
  • a vertically reciprocable mandrel forms the flat blank into a U-shape in one of these pockets.
  • Both the mandrel and shroud are mounted on a shifting carriage so that as the mandrel is moved to an inactive position, the shroud shifts the arrays of articles onto the bottom panel of the U-shaped carton blank. Flap folding devices then fold certain of the end flaps of the carton and the shroud is then raised clear of the partially formed box so that the top panel can be folded. The manufacturers flap and certain other end flaps are then folded up and the box conveyed by the pocket chain conveyor to a horizontal compression unit, Another version of this packer is adapted to handle single arrays in nested configuration for achieving a very tight pack,
  • FIG. I v FATENTEU FIG6 SHEET 5 BF 5 I02 200 1 H -i- -T- J H il Ii 1 I611 I08 I FIG. I v
  • This invention relates generally to forming a packing case around a slug of articles, and deals more particularly with a machine for handling either one, or more than one, slug of articles to be included in a single case.
  • U.S. Pat. No. 2,997,830 shows a machine for forming a multi-tier load of regularly shaped articles wherein the upper tiers are not positively supported but wherein the load is transferred into a generally U-shaped carton blank.
  • the case, with its load, is moved through successive folding stations by a pocket chain conveyor which has sets of removable and replaceable blocks to allow the machine to accommodate loads of various size and cartons of corresponding configuration.
  • the present invention not only provides an improved load handling mechanism with improved control of the load, but also allows the size of the load and of the cartons to be conveniently changed by the machine operator without any necessity for removing and replacing pocket defining blocks.
  • flat carton blanks are fed to a blank infeed station below a vertically reciprocable mandrel which folds the carton into a U-shape.
  • the articles are formed on a lift table in an orderly array and then raised up to be supported by a vacuum device provided for this purpose in an inverted U-shaped shroud.
  • the shroud and the mandrel are both mounted in a transfer carriage which shifts the load after a double tier of articles has been so formed, one in the shroud, the other on the lift table.
  • a depending leg of the U- shaped shroud will slide the lower tier off the lift table and into the U-shaped carton and at the same time, the mandrel which so formed the carton, will be retracted and shifted to an inactive position by the carriage.
  • the U-shaped carton and its load are formed in a pocket defined by two side-by-side conveyors or chains which operate together to move carton and load to a succeeding station for further folding and gluing up of the flaps.
  • a novel horizontal compression unit permits folding of the trailing manufacturers flap while the case is discharged from the pocket chain conveyor.
  • a single slug of articles is formed on a deadplate and the U-shaped shroud structure has depending legs which include camming devices for shifting alternate rows of articles in opposite directions relative to one another and by approximately one half of an article diameter.
  • these rows are nested by side guides to fit between the upright side panels of U-shaped blank.
  • bottom panel of the blank has a length and width to accommodate the nested array, and the various end flaps are folded up and glued as in the above-described embodiment.
  • FIG. 1 is a schematic view of the carton and its contents as they are handled by some of the more essential components of a machine embodying the present invention.
  • FIG. 2 is a side elevational view taken generally on the line 2-2 of FIG. 1.
  • FIG. 3 is an end elevational view taken generally on the line 3-3 of FIG. 1.
  • FIGS. 2A-2F inclusively are views similar to FIG. 2 but showing this view at successively later instants of time during a machine cycle.
  • FIGS. 3A 3F inclusively are views similar to FIG. 3 but showing this view at successively later instants of time during a machine cycle.

  • FIG. 1 articles A, A are fed generally toward an article infeed station, to be described, in orderly rows and columns on a conventional article infeed conveyor 10.
  • Suitable lane dividers and other structures have been omitted from this view for clarity and as will be apparent from the description to follow, the various views of the arrays of articles and the carton blanks, as well as the structure shown schematically in FIG. 1, have been exploded to better reveal the manner of operation of a machine embodying the present invention.
  • Means defining an article infeed station is represented schematically by the three views of the same apparatus depicted generally at 12 in FIG. 1.
  • the articles are segregated by conventional grouping means (not shown) into arrays or slugs as indicated generally at 14.
  • a vertically reciprocable lift table structure, indicated generally at 16, is adapted to receive the first slug of articles 14 from the infeed conveyor 10 in the first step of forming the load for a'wrap-around carton C. After so receiving a first array or slug 14, the lift table 16 is I raised upwardly so that the first slug of articles is received in an inverted U-shaped shroud structure 20.
  • the shroud structure 20 is also reciprocably mounted in the machine as indicated generally by the actuator 22.
  • This actuator 22 will cause the shroud 20 to descend as the lift table 16 raises the first slug of articles 14 into the position shown in FIGS. 2. and 2A, 3 and 3A.
  • the views of FIGS. 2A and 3A correspond to" the second or mid-view of the article infeed station 12 in FIG. 1.
  • FIGS. 2 and 3 show the inverted U-shaped shroud 20 in somewhat greater detail, and referring more particularly to FIG. 3, it will be apparent that this shroud structure 20 is mounted for vertical movement in a carriage 24.
  • the carriage. is itself movably mounted for limited horizontal shifting movement between the position shown in FIG. 3 andthat shown in FIG. 3C.
  • a series of vacuum cups 26 is provided in the carriage 24 and more particularly in association with the vertically movable shroud 20 and serves to hold the articles in the first slug referred to above in the U-shaped shroud during the horizontal shifting movement of the carriage.
  • a carton blank C is simultaneously folded into a generally U-shaped configuration at a box forming station 34 so that the double tier load can be received therein as indicated generally by the arrow 30.
  • a machine embodying the present invention includes a suitable magazine structure for storing a stack 32 of flat carton blanks. Means (not shown) is provided for withdrawing the lowermost blank in the stack and transferring it to the box forming station 34, indicated in exploded configuration.
  • the box forming station 34 also shows an initially flat box blank C as a first step in forming the box at said station, with sequential views showing the blank as it is being folded, and corresponding generally to the views depicted in FIGS. 2 and 2A, 3 and 3A.
  • the U-shaped shroud structure 20 will move the double tier load between the upstanding side panels of the box blank thereby providing a very high degree of control over the articles as a result of the depending legs of the 'U-shaped shroud, and the upstanding side panels of the U-shaped blank.
  • the load can be seen to follow a substantially horizontal path through the machine of FIG. 1, and this design concept carries through the entire machine, even to the horizontal compression section to be described. Only the requirement for lifting every other slug at the article infeed station sees any departure from this design concept.
  • a pair of side-by-side pocket defining chain conveyors 36 and 38 each carry one side member of a pocket defining structure, indicated generally at 40 and 42 respectively, and several such pocket defining members are arranged in spaced relationship in each of said chains.
  • a conventional intermittent drive mechanism, indicated generally at 44 is provided to advance these pockets as indicated in FIG. 1.
  • each such pocket issequentially presented to the box forming station 34 and it is an important feature of the present invention 1 that two such chain conveyors are provided, each one of which chain conveyors carries one side of each of the individual pocket defining structure.
  • Both chains are driven from a common drive mechanism 44, but each chain conveyor is independently adjustable one with respect to the other through a clutching device 46 in order to permit setting up the machine to form boxes of various size.
  • the lowermost blank in the stack 32 is fed to the box forming station immediately above a stationary pocket on the intermittently driven pocket chain conveyor, as best shown in FIG. 3 of the drawing, and more particularly as indicated generally at reference numeral 50.
  • the initially flat box blank 50 is supported by guides (not shown) and a box forming mandrel is slidably mounted in the carriage 24 for vertical movement in response to actuation of a fluid actuator 54.
  • a box forming mandrel is slidably mounted in the carriage 24 for vertical movement in response to actuation of a fluid actuator 54.
  • the lift table 16 is shown raising the first slug of articles at the article infeed station upwardly into the shroud 20, which shroud has been lowered slightly so that the vacuum cups 26, 26 will engage the upper sides of the articles to hold them in place.
  • the lift table 16 is then lowered for receiving the next slug of articles.
  • a depending skirt 17 is provided on the lift table 16 to prevent articles from prematurely moving 'off the infeed conveyor 10.
  • a lip 15 is also provided on the lift table 16 for controlling the position of both the first and second slugs of articles being handled by said lift table. Still with reference to FIG.
  • vacuum manifold 25 is provided in the carriage 24 to selectively connect the vacuum cups 26, 26 to a source of pressure that is less than atmospheric in order to securely hold the first slug of articles during the transfer of the double tier load from the FIG. 3B position to the FIG. 3C position.
  • the second, or lower slug of articles in the double tier load of FIG. 3B is positively shifted or transferred as a result of the depending leg 21 at the rearward side of the inverted U-shaped shroud 20.
  • the forward leg of the U-shaped shroud serves to positively control the load as it decelerates after having been transferred to the box forming station 34.
  • the lower or second slug of articles can be controlled as it is shifted horizontally off the lift table 16, across a deadplate (not shown) and onto the bottom panel of the generally U-shaped box blank 50 as shown in FIGS. 38 and 3C.
  • the carriage 24 can be seen to be slidably received for this horizontal shifting movement in a guideway 25 defined in the fixed frame of the machine.
  • the carton blank 50 comprises a conventional wraparound carton blank which includes a bottom panel together with associated side panels and a top panel connected to one edge of one of the side panels.
  • the top panel carries a manufacturer's flap, which is preferably oriented at the forward end of the blank at the box forming station 34.
  • the top panel is preferably folded back upon itself at least initially in a direction opposite that which it will ultimately assume, as indicated generally at the box forming station 34, and as suggested in FIGS. 2A and 2B.
  • End flaps are associated with the bottom panel, the side panels and the top panel as is conventional with a typical wraparound carton blank. The mechanism for folding up these flaps will now be described in detail.
  • FIGS. 2D and 3D show a trail ing end flap closing device 60 after having folded the trailing end flaps from the FIGS. 2C and 3C positions.
  • the flap folder 60 is of conventional construction, and serves to fold the trailing end flap through 90, where these flaps are held by the guide rail 64 of FIG. 2E. This rail 64 serves to fold the leading end flaps as the box is moved downstream from the box forming station as shown in FIGS. 2E and SE.-
  • a top flap folding device 66 is arranged to fold the top panel back in its proper direction as suggested generally in 2E and 2F. This folding of the top flap will be accomplished as the pocket chain conveyor system moves the partially folded carton blank together with its contents out of the box forming station and downstream as indicated generally by the arrow 68 in FIG. 1. Prior to this motion of the pocket chain conveyor system, it will be apparent that the shroud 20 must be retracted from the position shown in FIG. 2D to that of FIG. 2E. It is also noted that the vacuum cups 26, 26 are deactivated to release the upper slug of articles prior to raising of the shroud 20. The end flap folding device 60 associated with the trailing end flaps of the side panel of the carton blank are also activated prior to movement of the pocket chain conveyor system.
  • the pocket chain conveyor systern serves to advance the box, together with its contents, toward a deadplate which comprises part of the manufacturers flap folding apparatus of the present machine.
  • a limited switch 82 will be actuated in response to transfer of a box onto the deadplate 80 and this limit switch 82 initiates a series of events for folding the manufacturers flap as follows.
  • a vertically reciprocable plow 84 is raised as shown in FIG. 5A.
  • the vertically reciprocable plow 84 is itself mounted on a horizontally reciprocable structure including an actuator 88.
  • the actuator 92 extends as shown in FIG. 5B.
  • the manufacturers flap is provided with a fast setting adhesive by a device 73 in FIG. 1, as is conventional practive.
  • a device 73 in FIG. 1 When a succeeding box is fed onto the deadplate 80 as shown in FIG. 5B, and when the actuator 92 has fully extended, the plow 84 descends folding the flap 86 as shown in FIG. 5C.
  • the manufacturers flap of the preceeding case will be held in position by this next case to set the adhesive in what amounts to a horizontal compression unit.
  • Side belts may be provided in this horizontal compression unit as is conventional practice to restrict the freedom of horizontal movement of the packing cases being compressed therein.
  • FIGS. 6 ll inclusively
  • the preceding embodiment is quite similar to the alternative one in that the load of articles is handled in a controlled manner and restricted to motion in a horizontal plane only.
  • the alternative embodiment provides for handling a single slug of articles rather than the double tier load shown in FIGS. 1 5 inclusively, and also utilizes an improved method and means for compacting the load prior to transfer to the U-shaped blank to permit a tighter pack in the resulting box. From the description to follow, it will be apparent that the apparatus of FIG. 1 could be adapted to handle single slugs of articles with or without the load compacting feature to be described.
  • a charge or slug of articles A, A is formed on a deadplate 16a which need not comprise an elevator or lift table such as that described above, but which deadplate 16a receives columns of articles from the infeed conveyor 10 in much the same manner as described above with reference to the article infeed station of FIG. 1.
  • Lane defining means I00 is preferably provided over the infeed conveyor 10 as is conventional practice, and line brakes 102 are also provided to interrupt the flow of articles once a slug or charge has been formed as shown in FIGS. 6 and 7.

  • retractable lane defining plates 106, 106 are initially raised, as shown in FIG. 7, but are retracted once the slug is' formed to the FIG. 6 configuration.
  • FIG. 9 shows the retracted position of these plates 106, 106 and it will be apparent from this view that all of these plates are carried on a common rock shaft 108 so as to be conveniently retractcd from the FIG. 7 to the FIG. 9 position.
  • the inverted U-shaped structure 20a descends just as described above with reference to the first embodiment.
  • the leading and the trailing legs, 19a and 21a respectively, of this U-shaped structure 20a unlike those of the shroud 20 in FIG. 1, have inwardly facing camming devices 110, 110 and 112, 112 respectively, which shift every other row of articles ad depicted in FIG. 8.
  • the article engaging surface of these devices 110 and 112 is preferably. inclined as shown in FIG. 11 to better accomplish this shifting motion of the slug rows.
  • the present invention takes advantage of this space between rows to compact the slug as it is transferred by the U-shaped structure from the deadplate 16a onto the bottom panel of the carton blank (FIG. As the slug is so transferred, side guides 114 and 116 (FIG. 8) squeeze these rows into a more compacted or nested relationship to the extent permitted by the inside dimension of the devices 110 and 112 on the U-shaped structure 12a. In fact, except for the slight spacing achieved by shifting adjacent rows of articles in opposite directions, the slug of articles to be packed is well controlled in the apparatus shown.
  • the retractable plates keep the articles in orderly columns and rows, and as the U-shaped shroud descends, the lane detectors 104, together with the row of articles held back by the line brakes 102, restrain the articles in one direction while the devices 110 and 112 do the restraining in the other direction.
