Patented Juno 7, 1932 UNITED STATES PATENT OFFICE IRVING \T. GLNNON, OF WILLOUGEBY, AND GUY E. LINN, OF RITTMAN, OHIO, ASSIGNORS TO THE OHIO BOXBOARD COMPANY, OF RITTMAN, OHIO, A CORPORATION OF OHIO CUTTING DIE FOR SLOTTING MACHINES Application filed October 28, 1930. Serial No. 491,784.
This invention relates to machines for slotting partition members for the so-called honeycomb partitions used in packing and shipping containers such as bottle cases, egg boxes, boxes for incandescent electric lamps and the like; and it relates particularly to an improvement in the cutters for slotting machines of the type known as the Staude automatic partition slotting machine disclosed in the patent of George A. Fisher and John A. Morrison, No. 1,012,538, dated December 19, 1911.
As is well known, the formation of V- shaped leading ends or entrance openings in the partition slots at the edges of the partition members greatly facilitates the assem bling of the members in hone comb form, and one object of this invention is to proyide the cutters of the slotting machine with means whereby these V-shaped leading ends may be formed simultaneously with the formation of the slots.
Another object of the invention is to so form the cutters that in addition to forming the V-shaped leadin ends they may be adjusted to cut slots 0 any desired depth, and still have the V-shaped leading ends properly arranged at the edges of the partition members, as desired.
The invention consists in the combinatio with a partition slottin machine, of cutting dies for forming the s ots in the stock for forming the partition members, these cutting dies including slotting knives and V-shaped cutter members for forming similarly shaped notches or leading ends in the slots formed by'the slotting knives, and the knives being adjustable relatively to the V-shaped cutter members so that the de th of the slots may be t ier be explained. more In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a sectional side view of a partition slotting machine of the typehereinabove referred to provided with the cutting dies of the invention. Fig. 2 shows a plurality of partition members of various dimensions slotted in accordance with the invention. Fig. 3 is a plan view of a conventional assembly of partition members forming a honeycomb partition. Fig. 4 is an enlarged side View of the male cutting die of a pair of cutting dies constructed in accordance withthe invention, the opposite side to that shown in Fig. 1 being illustrated. Fig. 5 is an-edge view of the cutting die of Fig. 4. Fig. 6 is a section taken on line 66 of Fig. 4. Fig. 7 is a further enlarged detail perspective view of the two cutter members for forming the V-shaped notches. Fig. 8 is a side elevation of the female cutting die complemental to the male (lie of Fig. 4. .Fig. 9 is an edge view of same. Fig. 10 is a section taken on line 1010 of Fig. 8.
The slotting machine illustrated conventionally in Fig. 1, includes a bed 1, an adjustable hopper 2 in which are evenly stacked the blanks 3 from which the partition members are formed, two power driven cutter shafts 4 and 5 driven in opposite directions, as indicated, and upon which the cutters are mounted, and an intermittent feed mechanism including the slide 6 reciprocated by a cam and roller mechanism 7-8 driven by suitable gearing 9 in proper timed relation to the rotation of the shafts 4 and 5. The machine includes also a plurality of stripper fingers 10 and cleaner fingers 11, a delivery chute 12, a waste receiving box 13, a guard 14 and other adjuncts which enhance its perfection of o eration.
As herein efore indicated, partitions hav-.
ing V-shaped notches at their slot entrances are well known, and various machines have been devised for their manufacture, but all of these machines, so far as the prior art discloses, are of the reciprocating punch and die type.
Rotary slotting machines of the type illustrated have manufacturing advantages over reciprocating punch and die machines and, as previously pointed out, it is to the adaptation of these rotary slotting machines for slotting partitions with V-shaped entrance notches that this invention is primarily directed.
This adaptation is made by substitutin for the cutting dies customarily employed other modified cuttin dies having the characteristics now to be escribed.
These cutting dies are provided in pairs in the forms illustrated in Figs. 4 and 8, each 5 pair comprising a male cutting die (Fig. 4)
and a female cutting die (Fig. 8) so arranged on the shafts 4 and 5 respectively that they will cooperate in slotting relation. As many of the pairs of cutting dies are ar- 10 ranged upon the shafts 4 and 5 as there are to be slots in the partition members operated upon, and they are appropriately spaced as desired.
As will be seen, the shafts 4 and 5 are provided with splines 15 and 16, respectively, whose relative angular relation has a definite purpose, as will later appear.
Inasmuch as all of the male cutting dies and all of the female cutting dies, respectively, are characteristically and structurally similar, a detailed description of one of each will suflice for all.
Referring to Fig. 4 to 7 inclusive, it will be seen that, in the form illustrated, the male cutting die comprises a disk 17 having a central shaft-engaging opening 18 and a hub 19. The inner face of the disk 17 is recessed, as indicated at 20, and is provided with an annular groove or slideway 21. An annular 80 disk 22 recessed at 23 complementally to the disk 17 and provided with an annular groove or slideway 24 complemental to the slideway 21 of disk 17, is slipped over the hub 19 with a sliding fit, and between the disks 17 and 22 are clamped one or more cutting knives 25 by means of clamping screws 26. The knife or knives 25 extend radially beyond the peripheries of the disks, and are provided with inner flanges 27 which engage in the annular grooves 21 and 24 whereby the knives are held against radial movement but may be adjusted circumferentially of the disks 17 and 22 when the clamping screws 26 are loosened.
If desired, the knives 25 may have their cutting edges serrated in a well-known manner (not shown) to enhance their cutting qualities.
Recessed into the eripheries of the disks 17 and 22 and secured thereto as by screws 28 are plates 29-29, each of which carries a wedge or half V-shaped. cutting member or lug 31 ofi'standing radially therefrom a distance equal to the radial projection of the knife or knives 25, and they are so relatively spaced that the knife or knives 25 may slide between them for purposes of adjustment. These cutting members or lugs 31, in combination, cut the V-shaped entrance notch of the slot and the knife or knives 25 cut the slot itself. Inasmuch as the V-shaped notch is at the edge of the partition member, it will be apparent that the circumferential extension of the knife or knives 25 beyond the points of the lugs 31 will determine the depth of slot cut, and that that portion of the knife which extends as indicated at 32 behind the butt ends of the lugs 31 will have no efiect upon the cuttin of the slot because it is beyond the edge 0% the partition member. Thus the knife or knives 25 may be adjusted to cut any depth of slot relatively to the V- cutting lugs 31.
The hub 19 is provided with a key-way 33 for cooperation with the spline 15 of the shaft 4, and this key-way is arranged in a predetermined position relatively to the lugs 31. In all of the male cutting dies the relationship between these parts, key-way 33 and cutting lugs 31 is the same, and thus when a group of cutters is arranged upon the shaft 4 the angular arrangement of all of the lugs 31 will be the same and all will register or index simultaneously with the edge of the partition member to simultaneously cut similar V-shaped notches.
In order that the cutters may be held in fixed spaced relation upon the shaft, each cutter is provided with a set screw 34.
The female cutting die comprises a disk 35 recessed as at 36 upon its periphery and provided with a central opening 37 to receive the shaft 5. \Vithin the recess 36 are mounted cutting plates 38 held in place by screws 39, and these plates are bevelled at one end as shown at 40 to form complements for the wedge-shaped edges of the V-notch cutting lugs,31 These plates, when the female cutters are properly arranged upon the shaft 5 and held thereon in adjusted position by cooperation of key-ways 41 with the spline 16 and by set screws 42, will cooperate with the knives 25 and lugs 31 to cut the slots in the partition members and form the desired V-shaped entrance notches.
The manner of adjusting the knife or knives 25 relatively to the lugs 31 to determine the depth of slot to be out has already been described. In addition to this adjust.- ment for depth of slot, the width of slot to be cut, dependent upon the thickness of the stock used for the partition members, may be provided for by substituting knives 25 and plates 38 of cooperating different thicknesses for those illustrated and by providing for cooperation therewith differently form'ed lugs 31. Obviously, the bevels 40 of the plates 38 will correspond with the shape of the lugs 31 used.
It will thus be seen that the cutters of the invention may be adjusted or furnished to cut any depth or width of slots desired and that always these slots will be provided with the V-shaped entrance notches.
It will be understood, of course, that the female cutting dies will be so arranged axially and angularly of the shaft 5 that they will register in proper cutting relation with the male cutters on the shaft 4 as the two shafts rotate.
Inoperation, with the cutters thus properly relativel adjusted, as the partitlon blanks are fe one by one in timel relation to the rotation of the cutters, the edge of the blank will be V-notched by the lugs 31, and
' box 13.
III)
