Waters, Chicago, n1. Application March 31, 1938, Serial No. 199,128 23 Claims. (cl. sis-58.2)

This invention relates to improvements in box blanking machines.

It is the primary object of the invention, broadly stated, to provide a machine by which box blanks can be manufactured with greater speed and at less expense than has heretofore been possible.

More specifically, the objects of the invention include the provision of means whereby inexpensive material may be scored longitudinally of the grain without any danger of cracking; the provision of an improved distributing means having a purely rotative motion whereby it functions more smoothly than the reciprocating or oscillatory deflectors heretofore used; and the provision of a machine in which the cutting and scoring die rolls and distributing rolls areunitarily assembled on a single sub-frame mounted on the machine bed for unitary interchange with other sub-frames, whereby the time and labor required to convert the machine for manufacturing boxes of different sizes and shapes is reduced to a minimum. In this latter connection it is important that the present machine takes into consideratlon the relation of the interchangeable units to the delivery belts and to the electric eye mechanism by which the functioning of the die and distributing rolls carried by the aforesaid units is made to synchronize with the printed matter carried by the web stock from which the box blanks are scored. v Other objects will appear in moredetail from the following disclosure wherein my invention is exemplified.

Like parts are identified by the same reference characters throughout the several'views.

While the particular source of web stock is broadly immaterial to the present invention, it 26 has a certain significance from an environmental standpoint in determining some specific details hereinafter to be disclosed. Consequently the preferred arrangement for feeding the web .is disclosed in full.

It is preferred to use a two ply web made up of relatively heavy box board drawn from a parent roll at I5 about guide rolls l6 and H, to which is glued a relatively lighter calendered and printed paper ply drawn from a parent roll l8 about guide rolls I9, 20 and 2| and the gluing roll 23. The glue roll rotates in a glue receptacle 24. The conventional distributing roll 25 assures that the face of the glue roll 23 is uniformly coated with adhesive. The guide roll 20 is mounted on arm 26 by means of which it can beadjusted between the full and dotted line position shown in Fig. 1. When raised to its dotted line position it lifts the paper web clear of the glue roll 23, thus preventing the web from sticking to the glue roll if the machine is at rest.

When the guide roll 20 is lowered to a full line position it brings the paper web partially behind the glue roll so that the web has a partial wrap about the glue roll. This gives a relatively '50 prolonged contact of the web with the glue roll and promotes a perfect coating of the paper with adhesive. A

The web 21 01' box board and the printed and calendered web 28 of paper are brought together Iii rolls to and 4|.

by the pressure roll sets 29 and 30 to form the composite two ply web 35 from which the box blanks are cut and scored.

In accordance with the preferred practice of this invention, the die roll set hereinafter to be described cuts and scores at least two distinctly different blanks during each rotation. If the machine is making boxes without covers it is possible to make two box blanks per rotation of the rolls, and these may be alike or different, as desired, the die rolls and distributing rolls being made accordingly. In the usual operation the machine will manufacture two tray-like boxes each having a bottom and four sides, one such tray-like box being slightly larger than the other to constitute a cover therefor. In such case the machine is made up to produce a box and its cover in each rotation of the die roll set. The particular arrangement herein disclosed contains a further development in that the die roll length is adequate so that from one web width a box and cover can be out side by side. In this arrangement the positions of a box and cover are made to alternate to avoid waste. Ihis has been indicated in Fig. 9 wherein a box blank is indicated at 36 and a cover blank is indicated at 31. From the waste stock indicated by shade line at 38 I cut price display cards 39 to be packed in the boxes when filled.

It will be noted from Fig. 9 that the top or printed paper ply of the stock. is uppermost. The cuts which have been made in the web by the cutting dies are represented by solid lines in Fig. 9, while the scoring is shown by dotted lines in Fig. 9. The transverse scoring is made on the printed surface of the composite web, but I have found that any attempt to use similar scoring longitudinally of the composite web parallel with the grain thereof will result in cracking. This is overcome by double scoring the box board on the under surface of the web along closely adjacent parallel lines as indicated in Fig. 9 by the double dotted lines which appear whenever the scoring extends longitudinally of the web, as at 396.

This cutting and scoring is done by the die These, are mounted in a subframe 42 longitudinally adjustable and freely interchangeable upon the bed 43 of the main frame. Details of the cutting and scoring dies are shown in Figs. 10, 11 andl2, the cutting dies being illus- 4 trated at 45, the transverse scoring die at 46,

and the longitudinal scoring dies at 50.

The cutting dies and transverse scoring dies 45 and 46 work against the solid face of roll 4| which supports the box board ply 21 of the composite web 35. The longitudinal scoring dies 56 are mounted on the lower die roll 4| in pairs, as clearly shown in Figs. 10 and 12. They can conveniently be made by soldering or otherwise securing piano wire to the face of the die roll. The opposed surface of .die roll 40 preferably comprises a strip of leather as indicated at The pairs of scoring dies operate on the relatively soft box board ply 2! of the composite web 35.

The box board ply is sufficiently soft so that when the box'blank is folded upon the double score line which results from the use of this mechanism, the portion of the box board between the two score lines wrinkles up like the fold formed between two adjacent creases in the palm of a persons hand, thus resulting in a slightly rounded rather than a perfectly square corner for the box. No cracking or breaking occurs Where this construction is employed.

aromas The cutting dies 45 have substantially completely severed the composite web 35 so that the resulting blanks 36 and 31 can be very readily separated from the waste stock 38. This separation is achieved by means of rolls 55 and 56 which, instead of being cut from solid stock, are preferably assembled by mounting a series of disks or other 'deflecting means on the shafts 51 and 58 respectively. An example of the use of disks is best shown in Figs. 3 and 6. An example of other deflecting means in which no disks contact the web appears in Fig. '7.

The disks will not necessarily be uniformly spaced upon their supporting shafts in the manner shown in Fig. 6. On the contrary, one of the advantages of this arrangement consists in the fact that the disks may be positioned on the shaft wherever any portion of the work needs support. It so happens that the sets of blanks shown in Fig. 9 have their support-requiring portions so uniformly distributed as to result in the uniform spacing of the disks as illustrated in Fig. 6.

Each of the various disks hereinafter to be described as constituting the u per roll 55, is preferably provided with a peripheral groove at 550. The two disks 59 at each end of the series are of circular outline and not otherwise noteworthy. They support the flat portions of the box blanks.

Immediately within the disks 59 at the ends of the series are the disks 60 positioned ,to engage the leading and trailing flaps offthe successive blanks. Each of these disks has at one point of its periphery a projecting cam finger 6|, diametrically opposite which such disk is notched at 62. The cam fingers push the blanks downwardly for delivery by one conveyor while the notches receive the next successive blanks for upward deflection for delivery from another conveyor, as will hereinafter be explained.

Between the two sets of deflecting disks 60 are the three remaining disks 64 and 65, the disk 65 being in the center. The disk 65 has at diametrically opposite points square cut notches 66 (Figs. 6 and 8), while disks-64 have notches 61 (Fig. 6) which are similar except that they need not open completely through to the far sides of the disks,

being merely shouldered into one face thereof.

The aligned notches 66 and 61 are made to receive the cards 39 which are thrust therein for discharge. Stripping fingers at H notched at 12 to pass the points 16 (Fi 3) remove the waste material 38 from the points.

The outer pair of disks 15 at each end of the series which constitutes the lower roll 56 are of plain circular form. They coact-with the plain disks 59 of the upper roll to support the laterally projecting flat portions of the box blanks and they have no distributing function.

Next within the outer disks 15 are the disks 60 which coact with disks 66 and are identicaltherewith except that they are provided with the waste impaling points instead of with the coacting grooves 58. Each of the disks 80 carries the cam finger 6| and is eccentrically notched or shouldered at 62, as above described. The arrangement is such that in the rotation of the must pass thereabove.

At the center of the lower roll are the three disks 82, each of which is provided with a score displacement cam at 83 (Fig. 8) which thrusts the card blank 39 bodily into the score recess 66 provided by the opposing disk 65 of the upper roll 55. The blank 38, thus segregated from the path of the remaining portions of the web, is engaged by a stationary arcuately curved guide bar 84 which defines an upward path of travel for the card in coaction with the spaced stationary stripping finger 85 which forced the card out of its recess 66 and between the feed rolls 31 and 88 by means of which it is ejected from the mechanism.

By using disks as shown in Figs. 3, 6 and 8, I am able to provide full support even for relatively light stock pending the deflection of such stock upwardly or downwardly as the case may be. Where the stock is sufficiently heavyand is fed in a substantially horizontal plane by the cutting and scoring rolls 40 and M, I do not need the complete disks as above described, and In lieu thereof I may provide the cam fingers 6| with just enough of a hub 89 to enable the cam fingers to be mounted on the respective shafts 51 and 58 as shown in Fig. 7. In this instance there is no opposing disk and consequently there is no occasion for any recess, the space opposite each successive cam finger being wide open to permit of the deflection of the blank to one side of the wedge 8| or the other. Nevertheless these skeletonized devices may be regarded as rolls within the contemplation of this disclosure.

In any case the distributing rolls 55 and 56, howeverconstituted, are preferably mounted, together with the stripping fingers 1|, Bland 85, upon a bracket 90 which carries these parts from the sub-frame 42. In any change of design of the cartons a new set of die and scoring rolls is required, and a new set of distributing rolls 55 and 56 is required, and these changes likewise necessitate changes in the various stripping fingers aforesaid. Consequently all of these parts are unitarily mounted on the sub-frame 42 to be interchangeable as a unit on the machine bed 43.

The conveyors by which the blanks are carried away and stacked do not require alteration to meet every change of box blank design. However, the set of conveyors which initially receive the box blanks does require a certain change of position compensatory for varying sizes of die and distributing rolls which may be required. Accordingly the first discharge conveyor set is preferably mounted to' be adjustable as a unit on a subframe 95 longitudinally of the machine bed 43. While any desiredmeans of adjustment is permissible, I prefer to slot the overhanging rail of bed 43 as indicated at 96. This mode of adjustment, being well known, requires no further explanation.

The conveyor set mounted on sub-frame 95 comprises three sets of idler pulleys on the shafts 91, 98 and 99 respectively, and four sets of driving pulleys mounted on the shafts I00, IOI, I02 and I03, at the discharge end of the conveyor set. The pulleys on shaft 91 are connected by upwardly inclined belts I04 with the pulleys on shaft I00. Some of the pulleys on shaft 88 are connected by coacting upwardly inclined belts I05 with the pulleys on shaft IIlI, while other pulleys.

on shaft 98 are connected by downwardly inclined belts I06 with the pulleys on shaft I02. Ccacting with belt I06 is belt I01 connecting the pulleys on shaft 99 with the pulleys on shaft I03. Thus shaft 98 serves in common an upwardly inclined conveyor and a downwardly inclined conveyor. Shaft 98 also serves as a convenient means of supporting the weight of the wedges BI, the wedges being flxed against rotation with such shaft by means of the cross rod I08.

The blanks delivered between belts I04 and I05 are received on the stacking conveyor IIO to be removed and packaged as desired. The conveyor III is merely an idler which receives its motion by resting on the work on conveyor H and serves to direct on to conveyor III! the work ejected from the relatively high speed conveyor which includes belts I04and I05.

Similarly, an idling conveyor II2 directs on to the stacking conveyor II3 the work ejected between belts I06 and I01. preferablyv comprise narrow belts and may con stitute ordinary V belts. They operate at high speed so as to pull the blanks free of the waste stock. The conveyors I I0 and H3, 'on the other hand, move very slowly so that the work is stacked thereon in successively overlapping piles as indicated in Fig. 1. 1

The drive of the machine is'as follows:

The belts I04 and I- The motor H5 is connected by a belt II6 with a variable speed drive such as the Reeves pulleys H1 and H8 and the interconnecting belt A pinion I20 on the driven pulley II8 meshes with an intermediate gear I2I which drives the gear I22. This gear meshes with gears I23 on the lower pressure rolls 29 and 30 of the sets, and-gears I23, in turn, mesh with gears I24 on the upper rolls of suchsets.

A bevel gear I25 on the face of gear I22 drives a pinion I26 on the shaft I21 which leads into the differential type speed regulating set I28. 'As diagrammatically illustrated in Fig. 5, shaft I21 carries a differential gear I29. The opposing shaft I30 carries differential gear I3I. The ring gear I32 which is preferably a worm gear, carries the differential pinions I33. When the ring gear is stationary the motion of shaft I21 is uniformly transmitted to drive shaft I30 in the opposite direction of rotation. The. ring gear may, however, be driven by the worm I35 from motor I36 by means of a chain I31. Motor I36 is reversible and if it rotates in one direction or the other its motion is transmitted at a reduced speed to add or subtract an increment of rotation to or from shaft I30 as compared with the motion of the shaft I21, thus accelerating or decelerating slightly the drive of the dies with respect to the feed of the web through the pressure roll sets 29 and 30.

The motion of shaft I38 reaches the die and distributing roll units as follows:

The pinion -I30 meshes with bevel gear I39 which is formed on the side of the driving gear I40 meshing with gear I H on the lower die roll 4|. Gear MI in turn meshes with gear I42 on the upper die roll 42 and with the intermediate gear I43 which drives gear I44 on the lower distributing roll 56. Gear I45 on the upper distributing roll 55 receives motion from gear I44 on the lower distributing roll.

A belt or chain I46 driven by gear I44 transmits motion to shaft IN on which gear I48 meshes with gear I49 on shaft I02. Gears onshafts MI and I02 respectively mesh with gears on shaft I00 and shaft I03.

The stacking conveyors H0 and H3 are separately driven by a motor I50 and speed reducer I5I the motion of conveyor I I5 being transmitted by a chain or belt at I52 to conveyor H0.

The conveyor I54 upon which the cards are stacked is likewise separately driven by the motor I55 and speed reducer I56.

To control the functioning of the reversible speed regulating motor I36 there is an electric eye or photoelectric cell at I which responds to a registration mark printed at I6I on the face ply of the web. The face of the web is illuminated by a lamp I62 and each passage of one of the marks I6I beneath the photoelectric cell I60 energizes the conventional relay (not shown) in the amplifying and relay box I63 to close the circuit of motor I36.

To determine whether the motor shall be energized in the forward or rearward direction or not at all, a rotary switch generically designated by reference character I64 is connected by chain I65 with the die roll gear I to turn in unison therewith in a synchronized relation to the die roll. There are two arcuately elongated stationary contacts I66 and I61 spaced for approximately the arcuate extent of the movable contact I68. If the movable contact isexactly centered beneath the stationary contacts I 66 and H51, the closing of the motor circuit by the photoelectric cell will produce no rotative effect in the motor. If the switch contactor I66 registers with stationary contact I66, however, the closing of the circuit by the electric eye will rotate motor I36 in a direction to operate the differential gearing to accelerate slightly the speed of the die rolls. If the moving contactor I68 engages contact I61 at the moment the motor circuit is closed by the electric eye, then the motor I36 will operate in a reverse direction to retard slightly (by means of the differential gearing) the rotation of the die rolls with respect to the rotation of the pressure roll sets. Thus, once the necessary synchronism is established between the pre-printed web and the die rolls, such synchronism would automatically be maintained by the cooperation of the rotary switch and the electric eye and the regulating mechanism which includes motor I36 and the differential gear set I38.

In operation a composite web is assembled on the machine by gluing a previously printed paper on to the surface of a ply of relatively coarse box board. The composite web is fed in closely controlled synchronism between the die rolls 40 and 4| which cut box blanks and cards from the waste portions of the web and provide the-box double and very dull piano wire scoring elements carried by the lower roll and coacting primarily with the box board ply of the composite web.

The distributing rolls must likewise operate in synchronism with the die rolls and the printed pattern on the web and the blanks cut therefrom. The distributing rolls lift or depress alternate portions of the severed blanks from the normal path of movement of the web, thereby guiding such blanks to the ejecting conveyors. At the same time the distributing rolls are removing and ejecting the waste and removing and ejecting any cards which may have been blanked, for purposes of economy, from what might otherwise have been waste between the box blanks.

The ejecting conveyors deliver the box blanks on to stacking conveyors which are carried by a separate sub-frame as clearly shown in Fig. 1.

The ejecting conveyors are mounted on their own sub-frame adjustable on the bed of the machine. The dies and distributing rolls likewise have their own sub-frame, and in this instance the subframe is not only adjustable on the bed but may readily be lifted by a crane from the bed to permit an entirely different sub-frame and sets of die and distributing rolls to be substituted therefor.

In order to interchange the sub-frame 42 with another sub-frame carrying a different set of rolls, it is only necessary to make a very few mechanical connections. The drive from the differential regulator must be connected to one of the die rolls. The drive to the control switch I64 must be connected and the drive to the ejecting conveyor set must be connected. Naturally these several driving connections are made to facilitate the interchange of the die and distributing roll units.
