Definitions

  • flats The art of manufacturing flat, glued, folded paper boxes, termed "flats" herein, has progressed to the extent that folding and gluing machines produce the same at such high speed that it becomes a problem for the packaging operators, at the end of the stacking aprons, to keep up with production.
  • the flats advance along the stacker apron, or conveyor, in shirgled formation, with every 50th flat counted and displaced slightly laterally out of the longitudinal shingled formation, so that the packaging operators can visually note what is called herein a lift, of fifty flats, or some other desired number thereof, reach over the stacking apron and grip between both hands as many as constitute a convenient lift and carry successive lifts manually over into an empty carton, until a slug, or row, is achieved in the carton.
  • a slug of one or more lifts of fifty flats is normally more than one operator can handle in one trip and is like an accordian in that if great compression pressure is not used, or if one part of each flat is extra thick to form a bulge, or if the operator, usually a woman, becomes tired or careless a slug can easily become deformed and the flats fall all over the floor. While picking up such flats, the stacker continues to feed shingled flats to the operator so that the need for a practical packaging apparatus, capable of handling entire slugs at a time, becomes apparent to assure against such mishaps and to match the speed of production.
  • the cartons, or trays are delivered in flat, folded form, at high speed, by the conventional stacker apron of a folder-gluer onto a secondary apron travelling at a slower speed and are caused to advance thereon, erect on one edge, pre-counted, with the count visible by, for example, each fiftieth flat projecting laterally from the advancing stack.
  • lift is used herein to mean the number of flats an operator can lift between her hands and repeatedly carry from a stacker apron over to an empty packing case without undue exhaustion and physical strain during a day's work.
  • slug is used herein to mean the number of such flats which fills an entire row in an empty packing case, and such a “slus” is normally too heavy, clumsy, and elongated for an eperator to lift and carry between her hands.
  • the number of flats in a "lift” or “slug” varies with the stock, area, and weight of the type of flats being run.
  • the slugs are handled as units, without separation into carryable lifts, and are always supported on a surface while slid therealong or even when being turned for.inspection.
  • a slug transfer table is provided, in the longitudinal path of the advancing flats, at the end of the secondary apron, so that the operator can grasp the leading slug, slide the slug past a backstop onto the transfer table and either release it, to be held between the compressor ram and the rear gate backstop, or, if necessary, turn it 90° for inspection of adhesion and folding.
  • a case presenter within easy reach of the operator, presents flat, folded, tubular, corrugated cases, with the leading closure flaps folded back, individually and successively, to the operator, who grips the endmost case by the corners, erects it into an open tube and inserts it into the case gripper of a case turner unit.
  • the case gripper is preferably poised at a level above the level of the transfer table and includes a support tongue for forming a temporary barrier closing the bottom minor flaps of the case and includes guides for holding the top minor flaps open with the case on its side and its opening facing the operator.
  • a start button pressed by the operator brings the case gripper and its case down to the level of the transfer table so that the operator can actuate a push bar to push the compressed, and inspected, lift into the case. If another layer of flats is to be inserted in the case, the case turner unit automatically brings the case gripper down to a second level for receiving a second layer. It then automatically turns the filled case back to rest on its bottom, closes the bottom major flaps, closes the minor top flats, and ejects the case to a bottom and top taping machine.
  • a single operator has ample time to keep up with the discharge rate of a modern folder-gluer and is easily able to grip and erect a flat case and insert it in the case gripper, then grasp a pre-counted lift of flats, slide it onto the transfer table, turn it for inspection, compress it, and push the compressed lift into the case in the case gripper, and repeat the operation while the next lift is advancing the length of a lift.
  • a conventional stacker 21 is shown fragmentarily in Fig. 5, the stacker having a stacker apron 22 upon which the flats 23 are advanced in shingled formation, having been folded and glued at high speed on a folder-gluer, not shown, but of well known type.
  • Suitable, well known counting mechanism automatically displaces every fiftieth flat, such as shown at 24, so that the individual, successive slugs 25 and 26 are segmented, and visually separated, into pre-counted groups capable of being grasped between the hands of the single operator and usually of such length that, when compressed, the slugs will each fit in a corrugated case 27.
  • a secondary stacker apron 28 is provided, in continuation of apron 22, but having an upper stretch 29 advancing along the longitudinal path 31 at a speed lower than the speed of apron 22, both aprons being driven by a suitable power train connection to the folder-gluer, not shown.
  • a hold down belt 32, (Fig. 4) having a lower stretch 33 advaneing in the direction of advance of the flats 23, and a hold down roller 34, are provided above the end roll 35 of the primary apron 22 to assist in raising the advancing flats from shingled formation to upstanding, edge supported, formations as shown at 36 in Figs. 4 and 5.
  • the individual and successive slugs 25 and 26 advance in substantially upright position, supported on secondary apron 28 and resting on their lower edges such as 37, the leading flat 38 leaning slightly rearwardly.
  • the operator can place her left hand on the exposed face 39 of leading flat 38 and her right hand on the rear face 41 of the projecting, fiftieth flat, 24, and slide the segregated slug forwardly past the backstop means 46 onto the transfer table 47 of the slug inspection and compression means 48.
  • the compression means 48 includes the substantially horizontal transfer table 47, in longitudinal extension of, and at substantially the same level as, the upper stretch 29 of secondary stacker apron 28.
  • Table 47 is vertically movable by the scissors type levers 49 and 51 on base 52, so,that the table, or platform 47, is substantially at the same level as the level of upper stretch 29 of secondary apron 28 and in longitudinal extension of the path 31.
  • Table 47 may be a hydraulically actuated lift table such as manufactured by Southworth Machine Company of South Portland, Maine.
  • the table or platform 47 is substantially horizontal and includes a backstop end 54, proximate stacker apron stretch 29, an opposite compressor ram end 55, a pusher bar side 56, at the side of the operator station 45 and an opposite slug discharge side 57.
  • the one-way backstop means 46 is provided at the backstop end 54 of transfer table 47, in the form of upper, laterally extending one-way cantilevered element 59 and lower, laterally extending, one-way element 61, both transverse to the longitudinal path 31 of the slugs 25 or 26, but spaced apart by a space 62 sufficient to pass each slug as slid therethrough in the hands of the operator.
  • the upper laterally, extending, one-way cantilevered element 59 can be a rod 63 only, the operator merely tilting the slug rearwardly to pass it through the space 62 and then shifting the flats to vertical to be compressed against the rod 63.
  • the upper one-way backstop element 59 can also be a gate, pivotally mounted from a rod 63, cantilevered above the path 31 and vertically adjustable relative to _an upright post 64, there being a stop so that it will swing in the direction of movement of the slug from the stacker apron onto the transfer table, buj; will not swing rearwardly when the slug is compressed thereagainst.
  • the upper, one-way backstop element 59 comprises a row of leaf springs, such as 65, each extending downwardly,at a slight angle, from the cantilevered rod 63 and each having a roller 66 at its free terminal end, so that the slug will raise the springs 65 and rollers 66, in being passed thereunder, but the springs and rollers then spring downwardly behind each trailing flat in the slug to serve as the upper backstop element 59-during compression of the slug.
  • leaf springs such as 65
  • the lower backstop element 61 preferably is a shoulder 67 extending across the path 31, directly below the row of rollers 66 of the cantilevered upper element 59, so that each successive individual slug 25, or 26, slid through the space 62, drops behind the shoulder 67 to enable it to form an immovable, one-way, lower backstop against compression.
  • the post 64 is on the slug discharge side 57 of transfer table 47 in order not to interfere with the sliding of the pre-counted slugs through the space 62 onto the table 47, ready for inspection, assembly, and compression.
  • the rod 63 is vertically adjustable on post 64 to conform to the height of the slugs 25 or 26 by screw 68 and hand wheel 69 on post 64.
  • Compressor ram means 71 is provided at the compressor ram end 55 of the transfer table 47, and includes a compression head 72 having at least one, and preferably two, spaced apart laterally extending, compressor rams 73 and 74 each with a row 75, or 76, of freely revolvable rollers, such as 77, to reduce friction during push bar discharge of the compressed slugs, (Fig. 1).
  • the compressor rams 73 and 74 are normally retracted, but are movable along the longitudinal path 31 toward the backstop means 46 by pneumatic piston 78 and cylinder 79, to compress each individual and successive slug 25 or 26 when the operator presses a switch 81.
  • a longitudinal slot 82 in transfer table 47 accommodates the connection 83 between the tip of piston 78 and the compression frame 80.
  • Compression head 72 is clamped in place on table 47 by clamp knob 132 to adjust to the length dimension of the cases 27.
  • the compressor ram power mechanism 84 is pneumatic, so as to be yieldable in case the hands of the operator are inadvertently caught therein.
  • the source of air pressure is a suitable air pump and tank, or mill air, not shown.
  • Push bar means 85 is provided at the push bar side 56 of transfer table 47, adjacent the operator station 45 and consisting of a longitudinally extending bar 86, having a knob 87, and mounted on a wheeled carriage 88, movable laterally of path 31 on a track 89 in a slot 91 in table 47 (Fig. 3).
  • Slot 91 is formed by a space between the plate 90, forming the shoulder 67 and the underlying surface 70 of transfer table 47.
  • the single operator at station 45 can slide each slug 25 or 26, through the space 62, of the one-way backstop means 46 onto the slug compression and inspection table 47, turn the slug on its longitudinal axis 90° to inspect the folds and adhesion of the flaps and tabs, turn it back through 90°, if desired, press the compressor ram switch 81 to compress the slug against the backstops 59 and 61, and push the compressed slug 92 laterally across the table 47 and off the discharge side 57.
  • corrugated cases are stacked in flat tubular condition, near the operator station 45 as at 93, at case presentation station 94.
  • Case presentation means 95 at case presentation station 94, includes a magazine 96 holding a stack 97 of flat, tubular, corrugated cases 98, the magazine being of the bottom feed type with a gateway 99 for passing one flat case at a time and each successive lowermost individual flat case being advanced through gateway 99 by lugs 101. on a feed chain 102, powered by a suitable motor and arranged to advance another case to easy reach of the operator, each time the lowermost case is extracted.
  • Suitable back fold hooks 103 and 104 fold back the leading flaps 105 and 106 of each_ case, as it advances to presentation position, so that the operator can grasp the opposite corners, erect the case into an open tube and insert it into the case gripper 107.
  • Case turning means 108 is located on the slug discharge side 57 of the slug transfer and compression table 47, and includes the case gripper 107, which is normally at a level above the level of the surface 70 of the table 47.
  • Case turning means 108 is mounted on an hydraulically actuated vertically movable, table 109 having scissors type levers 111 and 112 on a base 113 and being movable.from level 0, through level 1, and level 2 to level 3 by the control mechanism 114 as required by the run of flats, and cases.
  • Case gripper 107 includes a right hand turning fork 115, and a left hand turning fork 116, each having one end such as 117 mounted to pivot with a shaft 118 through an angle of 90° (Fig. 3), the forks 115 and 116 being normally horizontal to support an empty case 119 resting on its side wall 121 with its top opening 122 facing the operator at station 45 and facing transfer table 47.
  • Case gripper 107 also includes the support tongue, or backer plate, 123 which is mounted about mid-height of the case 119 to close the minor, bottom end flaps of the case, as it is inserted, as an open tube, into the case gripper and to serve as a backer when the compressed slug is pushed into the case.
  • a left. hand case side hopper 124 is adjustably mounted on compression head 72 and a right hand case side hopper 125 is adjustably mounted on upright post 64.
  • Each case side hopper includes a pair of arms 126 and 127 having slots such as 128 for bolts such as 129 tightenable in vertical slots such as 131.
  • case gripper 107 positioned in its normal position at a level above the level of the transfer table, and directly in rear of the side hoppers 124 and 125, the operator in a single motion can withdraw a flat tubular case by the corners from the case presenter means 95, erect the case into an open tube, push it into the side hoppers and into the case gripper 107, the backer plate 123 closing the minor bottom flaps of the case and the upper minor end flaps being held back, out of the way, by rods such as 137.
  • the case gripper 107 When the operator presses the sequence start button 138, the case gripper 107 is automatically lowered to the level of surface 70 of table 47, the first load position, with an empty case 119 ready to slidably receive a compressed slug such as 92.
  • an alignment bar 139 is at this time in raised position along the discharge side 57 of table 47 so that the push bar can align the flats in the slug against the bar 139, whereupon it automatically moves out of the path down into a slot 141 so that the slug may enter the empty case.
  • the sequence control mechanism 114 has four levels, to which it automatically moves the case gripper 107 from its normal level 0, poised above the transfer table to receive an empty case 119, down to level 1, where the side wall 121 is flush horizontally with surface 70 of transfer table 47. If the case 119 is of a predetermined width sufficient to contain two or more slugs, such as 24 or 25, the control mechanism automatically moves the case gripper 107 down to level 2, as soon as the first compressed slug is inserted by the push bar 86, so that the upper edges of the inserted slug are flush horizontally with surface 70 of table 47.
  • a limit switch 142 at the end of the path of the carriage 88 of the push bar 86 signals the control mechanism 114 to lower the case gripper 107. to level 2 or to level 3, if three layers are desired in one case 119.
  • the limit switch 142 signals control mechanism 114 to turn the now filled case 119 through an angle of 90° back onto its bottom flaps, and resting on support tongue 123 (Fig. 3).
  • the top major flap 147 at opening 122 is sufficiently stiff to remain up and out of the way of insertion of a compressed slug 92 into the interior 148 of an empty case 119, as shown in Fig. 3.
  • the lower top major flap 159,.at the opening 122, is folded under the empty case 119.
  • the minor top flaps 151 and 152 at the opening 122, are held back by the rods 137.
  • a pair of gripper rolls 135 and 136 each on an opposite side of case gripper 107, and each rotatable on vertical axis, cooperate with support tongue 123 in maintaining each empty case 119, erect and fully open while the case is being filled.
  • the gripper rolls remain in position, while rotatably contacting the side walls of a filled case, as the support tongue 123, the left hand turning fork 116 and right hand turning fork 115 turn the filled case back to rest on its bottom ready for discharge.
  • the front major bottom flap 146 is upfolded against the other side of the under face 172 of the support tongue 123, by the deflectors 173 and by the lateral advance of the front flap closer bar 174 carried by gear racks 175, _slidable in tracks 176, and meshed with spur gears 177 on driven shaft 178.
  • the presser roll 179 cooperates with the underface 172 of support tongue 123 in holding the lower major bottom flaps 145 and 146 closed as the case 119 is advanced along the tongue 123..
  • a top rear flap closer 181 extends in advance of the case pusher 153 to engage the top minor rear flap 152 first and downfold it before the filled case is engaged by the pusher 153.
  • An elongated top front minor flap closer 182 extends along the path of the case being moved by the case pusher 153 to down fold flap 151 as the case advances towards the box taper.
  • the rear flap closer 181 advances with the case pusher 153 to hold down rear flap 152 until it passes under flap closer 182, whereupon the box taper, 183 which is of well known, commercially available, construction,closes over the top major flaps and applies adhesive tape along the top and bottom central seams of the filled case 119 in the usual manner.
  • control mechanism 114 All of the above operations are controlled and sequenced by the control mechanism 114.
  • the case gripper rolls 135 and 136 shown in Figs. 2, 3 and 4 are rubber covered and each is provided with a one-way clutch such as indicated at 134.
  • the operator can easily push the case into the grip of the rolls, with the clutch allowing rotation in the direction of advance without damage to the case, and once seated in the case gripper the case cannot bounce back toward the operator.
  • the case turning forks 115 and 116 can turn the filled case baek, onto its bottom by overpowering the soft, resilient tension of the gripper rolls 135 and 136, together with the cooperation of the one-way clutches during the compound motion of the case in its rearward curved path.
  • the apparatus of the invention may consist only of the transfer table with one-way backstop; or gate, means 46.at one end and an upstanding support at the other end, the case gripper being located at the loading level of the transfer table.
  • the operator would grasp each successive individual slug between the hands, slide it past the one-way gate onto the transfer table, turn it for inspection if necessary, manually compress it and slide it into the case gripper.
  • the pivoted forks and support tongue would then turn through 90° to rest the filled case on its bottom ready for discharge to the taper.
  • powered compression and automatic vertical movement of the case gripper is much preferred.
