2 Sheets-Sheet 2 ADJUSTABLE DIE PLATE BACKGROUND OF THE INVENTION The field of the invention relates to the fabrication of boxes, such as cardboard boxes.

One type of cardboard box fabricating machine has an elongated cylinder mounted therein for rotation. The rotary cylinder is hollow and has threaded holes which are evenly spaced longitudinally and circumferentially about the cylindrical wall of the longitudinal cylinder.

In the prior art, dies which included arcuate die plates with cutting and scoring blades mounted thereon were mounted by bolts in the evenly spaced holes in such a rotary cylinder to engage cardboard sheets as the rotary cylinder rotated. The dies performed cutting and scoring operations on the cardboard sheets so that boxes or other special purpose cardboard pieces could be formed out of the cardboard sheets. For instance, a series of four arcuate dies would be mounted on the rotary cylinder to cut and score a piece of cardboard in such a manner that the piece could easily be formed into an open or closed box having a certain style of corners.

In the manufacture of boxes, it is often necessary to fabricate similarly styled boxes of various sizes. However, to vary the length and width of a box being fabricated from four prior art dies mounted on the rotary cylinder, it was necessary to move three of the four dies to other evenly spaced holes in the cylinder. Thus, the variations in the length and width of similarly styled boxes were limited to the distances between the evenly spaced holes in the rotary cylinder. And, if it was necessary to fabricate a size of box that differed in length or width by some fraction of the distance between the evenly spaced holes, then new dies would have to be manufactured with the cutting and scoring blades in different positions.

Attempts have been made to vary one dimension, such as the length or the width of a box, by varying the longitudinal spacing or the circumferential spacing of the dies between the evenly spaced holes. However, insofar as known, no one has been able to successfully devise dies which can be adjusted on the rotary cylinder both longitudinally and circumferentially for distances less than the distance between the evenly spaced holes.

SUMMARY OF THE INVENTION.

It is an object of this invention to provide adjustable dies which provide for varying the dimensions of cardboard boxes made from cardboard sheets.

This and other objects are accomplished by providing an adjustable clamp which mounts an arcuate die plate on the rotary cylinder of a cardboard box fabricating machine. The clamp member engages the die plate and provides means for adjusting the position of said die plate both longitudinally and circumferentially a distance less than the distance between the longitudinally and circumferentially spaced holes on the rotary cylinder.

One feature of this invention is a system of four dies for making a cardboard box where the positions of the dies can be adjusted such that both the length and width of the boxes can be varied by distances which are some fraction of the distances between the evenly spaced holes.

BRIEF DESCRIPTION OF THE DRAWINGS The preferred embodiment of this invention will be described hereinafter, together with other features thereof, and additional objects will become evident from such description.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings forming a part thereof wherein an example of the invention is shown and wherein:

FIG. 1 illustrates a cardboard sheet which has been fabricated by the adjustable dies of the preferred embodiment of this invention;

FIG. 3 is a perspective view of the adjustable dies for cutting and scoring the other two comers of the cardboard sheet of FIG. 1;-

FIG. 4 is a detailed perspective view of the clamp member which provides means for adjusting a die plate both longitudinally and circumferentially of the rotary cylinder; 7

FIG. 5 is a perspective view of an adjustable die adapted for mounting at the end of a rotary cylinder; and

FIG. 6 is a detailed perspective view of the clamp member for the adjustable die of FIG. 5.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawings, the letter A generally designates a rotary cylinder which is mounted for rotation on a cardboard box fabricating machine (not shown). Roller means B which may take other forms, is a longitudinal roller B which is positioned adjacent to the rotary cylinder A in order to cause a cardboard sheet C, illustrated in FIG. 1 to be engaged by the rotating rotary cylinder.

A plurality of adjustable dies 10, ll, 12 and 13 are mounted on the rotary cylinder of the cardboard box fabricating machine in order to cut and score the corner areas of the cardboard sheet C so that a box can be formed therefrom. The rotary cylinder A has a plurality of evenly spaced holes 14 which are evenly spaced both longitudinally along the axis of rotation and circumferentially with respect to the rotary cylinder. The adjustable dies 10 and ll illustrated in FIG. 2 are mounted on one side of the rotary cylinder and the adjustable dies 12 and 13 shown in FIG. 3 are mounted on the other side of the rotary cylinder and are positioned such that the dies will engage the cardboard sheet C as the cardboard sheet is passed between the rotary cylinder A and the roller means B.

Before describing the actual structure and operation of the plurality of adjustable dies, it is necessary to examine the cardboard sheet C. The dotted lines l6, l7, l8 and 19 represent lines of indentation in the cardboard sheet which allow the cardboard sheet to be folded along these lines easily. These lines of indentation may be scored on the cardboard sheet C by means other than the rotary cylinder A and dies 10, ll, 12 and I3 described herein. Corner areas 20, 21, 22 and 2 3 of the cardboard sheet have slots such as 200 and a line of indentation such as 20b such that a box formed from the cardboard sheet C has identically styled comers.

The box that is formed from the cardboard sheet C is an open-ended box. The details of actually assembling the box are not related to this invention and are quite obvious to any person skilled in the area of fabricating boxes. The length of the box formed from the cardboard sheet C is the distance between the lines of indentation l7 and 19 and the width is the distance between the lines of indentation l6 and 18. After a box is formed from the cardboard sheet, the lines of indentation 20b, 21b, 22b and 23b allow the box to be flattened for shipping prior to use. In FIG. 1 the adjustable dies 10, I1, 12 and 13 are shown superimposed upon the cardboard sheet C to better illustrate the fabricating operations that the dies perform on the corner areas of the cardboard sheet C. The adjustable dies 10 and Il engage corner areas 20 and 21 as the cardboard sheet is passed between the rotary cylinder A and the roller means B cut slots 20a and 21a and indent or score" indented lines 20b and 21b. Similarly, the adjustable dies 12 and 13 engage the comer areas 22 and 23 and cut out slots 22a and 23a and score indented lines 22b and 23b.

As discussed previously, it is often desirable to change the length and the width of the box fabricated by amounts or distances less than the distances between adjacent evenly spaced holes 14 in the rotary cylinder A. In accordance with the preferred embodiment of this invention, the adjustable dies 11, 12 and 13 are provided so that an infinite number of box sizes may be fabricated using these dies. The adjustable die 10 includes an arcuate die plate 100 having a curvature such that it is adapted to conform to cylindrical wall 15 of the rotary cylinder. Mounted on the die plate 10a is a cutting blade 10b which cuts the slot 200 in the cardboard sheet C. A scoring blade 10c which is simply a blunt blade, is also mounted on the die plate 10a in order to score or indent the line of indentation b in the cardboard sheet as the sheet is driven between the die 10 and the roller B.

The die plate 10a is secured to the rotary cylinder by means of bolts such as 10d and l0e which extend through the die plate and threadedly engage threaded holes 14 in the rotary cylinder.

The adjustable die 11 comprises an arcuate die plate 11a adapted to be mounted on the rotary cylinder. A cutting blade 11b and a scoring blade 110 are mounted on the die plate 11a in order to cut the slot 210 and score the line of indentation 21b in the cardboard sheet C.

To adjust the length of the cardboard box to be fabricated means are provided for adjusting the position of the die plate 11a longitudinally with respect to the die plate 10a. This adjusting means is provided by the elongated slots 11d, He and 11f which extend longitudinally with respect to the rotary cylinder. Elongated washers such as 11g are counter sunk in the elongated slots in the die plate 110 to protect the die plate. Mounting means or bolts such as 11!: extend through the elongated slots to mount the die plate 110 on the rotary cylinder. The bolts 11h, when screwed to a position out of engagement with the washers 11g, allow the position of the die plate 11a to be adjusted longitudinally between adjacent, longitudinally spaced holes in the rotary cylinder. When the bolts are tightened down against the die plate 110, the die plate is secured on the rotary cylinder.

The elongated slots Ild, 11c and llf are approximately equal in length to the distance between any two adjacent, longitudinally spaced holes such that the die plate is adjustable to any fraction of the distance between two longitudinally spaced adjacent holes. Of course, if it is desired to adjust the length of the box more than a fraction of the distance between two adjacent, longitudinally spaced holes in the rotary cylinder, the bolts llf are simply moved to another of the longitudinally spaced holes and then the die plate is adjusted to whatever fraction of the distance between adjacent holes is necessary to attain the desired new length for the box to be manufactured.

A third adjustable die plate 12 also comprises an arcuate die plate 12a with a cutting blade 12b for cutting the slot 22a in the cardboard sheet and a scoring blade 12c for scoring the line of indentation 22b in the cardboard sheet.

The die plate 12a is mounted such that the position of the die plate is adjustable even to fractions of the distance between adjacent circumferentially spaced holes in the rotary cylinder. Arcuate, elongated slots such as 12d and 12e are cut in the die plate such that their longitudinal axis extends circumferentially with respect to the rotary cylinder. Arcuate elongated washers 12f and 12g are countersunk in the slots and bolts 121 and 12: extend through the slots 12d and 12e, respectively, in order to secure the die plate 120 on the rotary cylinder. With the bolts 1212 and 12i out of engagement with the elongated washers 12f and 12g, respectively, the die plate 120 is adjustable circumferentially with respect to the adjustable dies 10 and 11.

The length of the elongated slots 12d and 12e is substantially equal to the distance between adjacent, circumferentially spaced holes in the rotary cylinder such that the die plate 12 can be adjusted to any fraction of the distance between adjacent circumferentially spaced holes. As a point of interest, a circumferential scale 25 may be provided for ease in measuring linear distances in a circumferential direction about the cylinder.

The adjustable die 13, which is adjustable both longitudinally and circumferentially with respect to the other dies so that both the width and the length of a box can be adjusted, includes an arcuate die plate 130. A cutting blade 13b is mounted on the die plate to cut the slot 23a in the cardboard sheet and a scoring blade 13c is mounted thereon to score the line of indentation 23b in the cardboard sheet. One side of the die plate 13a is offset to provide mounting surfaces 13d, 13c and 13f; and, in a similar manner, the other side of the die plate has the mounting surfaces 13g, 13!: and 131'.

In order to adjust the die plate 130 both longitudinally and circumferentially with respect to the other dies, clamp members 30, 31, 32 and 33 are mounted onto the rotary cylinder against the die plate 130. Since the clamp members are identical, except for being disposed against opposite mounting surfaces on the die plate, only the clamp member 30 illustrated in FIG. 4 will be described in detail. The clamp member 30 has a substantially elongated slot 31 extending through the clamp member. The slot 31 is recessed such that a mounting surface 31a is provided.

The clamp member 30 is offset to provide a mounting face 32, which is adapted to engage the corresponding die plate mounting surface 13f. A mounting face 33 is adapted to engage the corresponding mounting surface l3e on the die plate; and, a mounting face 34 is adapted to engage the corresponding mounting surface 13d on the die plate.

A mounting bolt 35 extends through the elongated slot into threaded engagement with a hole in the rotary cylinder and bolt head 35a is seated on the recessed mounting surface 31a in the slot to secure the clamp member against the rotary cylinder.

A threaded nut 36 extedns through a threaded hole 37 in the clamp member and mounting face 33 to engage the corresponding mounting surface l3e to further secure the die plate against circumferential movement on the rotary cylinder. The clamp member 31 is mounted against the mounting surfaces 13d, l3e and I3f in a manner similar to the clamp member 30; and the clamp members 32 and 33 are mounted against the mounting surfaces 13g, 13h and 131 on the other side of the die plate 13a in a manner similar to the clamp member 30.

In order to adjust the position of the die plate 13a both longitudinally and circumferentially with respect to the other die plates, the bolts, such as the bolt 35 extending through the slot 31 in the clamp member 30, are loosened from the clamp members and the threaded nuts, such as the threaded nut 36 for the clamp member 30, are also loosened. With the bolts loosened or out of engagement with the recessed surfaces such as 31a of the slot 31 in the clamp member 30, the clamp members and the die plate are adjustable longitudinally with respect to the dies and 12 so that the length of the box to be manufactured may be varied, even to a fraction of a distance between adjacent, longitudinally spaced holes in the rotary cylinder.

The die plate 130 is also adjustable circumferentially with respect to the rotary cylinder A, and the loosened clamp members 30, 31, 32 and 33 by sliding the die plate 13a circumferentially with respect to the loosened clamp members 30, 31, 32 and 33. In this manner, the width of the box may be adjusted, even to a fraction of the distance between adjacent circumferentially spaced holes in the rotary cylinder. After the die plate 130 is in its adjusted position, the bolts, such as the bolt 35 for the clamp member 30, are tightened down into the elongated slots so that the clamp members secure the die plate against the rotary cylinder.

The threaded nuts such as 36 for the clamp member 30 may then be tightened against the corrsponding mounting surfaces 132 and 13h so that the die plate is further secured against the rotary cylinder. With the clamp members secured against the rotary cylinder, the faces 32, 33 and 34 on the clamp member 30, cooperate with the similar faces on the other clamp members to engage the corresponding mounting surfaces 13d, 13e, 13f, 13g, 13h and l3i to secure the die plate against any movement longitudinally or circumferentially. For example, mounting face 33 in the clamp member 30 secures the die plate 13a against movement circumferentially while the mounting faces 32 and 34 secure the die plate against movement longitudinally with respect to the rotary cylinder. I

Adjustable dies mounted on rotary cylinders may be used to perform other fabricating operations on cardboard sheets than providing corners for cardboard boxes. Referring to FIG. 2, an adjustable die 40 is mounted onto the rotary cylinder by clamp members 41 and 42 in order to cut a hole 43 in the cardboard sheet C. The adjustable die 40 includes a die plate 40a which has a circular blade 40b mounted thereon in order to actually cut the hole 43. The clamp members 41 and 42 are identical to the clamp member and, the die plate 60a is offset with mounting surfaces similar to the mounting surfaces 13d, 13c and l3fon the die plate 13a so that the clamp members 41 and 42 can be mounted on the rotary cylinder against the die plate 400. The clamp members 41 and 42 thereby allow the position of the die plate a to be adjusted both longitudinally and circumferentially on the rotary cylinder to any position desired. And, the position of the die plate 40a to be adjusted even distances which are only a fraction of the distance between the adjacent circumferentially spaced holes or adjacent longitudinally spaced holes in the rotary cylinder.

Sometimes it is necessary to mount a die near an end 15a of the rotary cylinder. Since the edge 50a of the die plate 50b for the die is quite close to the end 15a, it is not desirable to mount clamp members such as the clamp members 30 at the die plate edge 50a since they would extend over the end 1150 of the rotary cylinder and thereby interfere with the operation of the cardboard box fabricating machine. In this situation a rectangular aperture 50c may be cut in the die 50 and, mounting surfaces 51, 52 and 53 may be offset on one side of the aperture and mounting surfaces 54, 55 and 56 may be offset on the other side. In order to adjust the die 50 both longitudinally and circumferentially distances which are a fraction of the distance between adjacent holes, a clamp member 60, which is shown in detail in FIG. 6, may be mounted in the aperture 50c against the mounting surfaces of the die plate 50b. The clamp member 60 is substantially similar to the clamp member 30 already discussed except that the clamp member 60 has mounting faces machined at both ends 60a and 60b.

A elongated slot 600 is cut in the clamp member, and a bolt 61 is mounted in the slot with the bolt head 61a engaging recessed surface 60d in the slot when the clamp member is secured-against the rotary cylinder. At the end 60a of the clamp member, the lamp member mounting faces 62, 63 and 64 are adapted to engage the corresponding die plate mounting surfaces 53, 52 and 51, respectively. Similarly, the clamp member mounting surfaces 65, 66 and 67 at the end 60b of the clamp member are adapted to engage the corresponding die plate mounting surfaces 56, 55 and 54 in the aperture 50c. A threaded nut 68 is mounted for threaded engagement in a hole 69 extending through the mounting face 66 of the clamp member to engage the corre' sponding die plate mounting surface 55 and, a similar nut 70 is threadably mounted in a hole 7il-and may be rotated into engagement with the corresponding surface 52 in the aperture 56c.

With the bolt 61 loosened out of engagement with the clamp member 60, the die plate 50 is adjustable both longitudinally and circumferentially even distances less than the distances between adjacent holes similar to the other adjustable die discussed herein.

Of course, it is to be understood that the configuration of the cutting blades and scoring blades discussed herein and their relative positions on the die plates and the cardboard sheet C are merely a simple illustration of the styles of boxes that may be fabricated. It is to be understood that any form of box including open ended and closed boxes may be fabricated. For example, it is within the scope of this invention to provide adjustable one piece folder dies and five piece folder dies for making enclosed boxes.

In the preferred embodiments discussed herein the series or system of four adjustable dies 10, ll, 12 and 13 have been described for fabricating a box from the cardboard sheet C shown in the drawing. Also, the single adjustable die 40 has been described for cutting a hole in the cardboard sheet C. It is to be understood that the number of dies used in fabricating a box or in performing some other cutting or scoring operation on a cardboard sheet such as cutting a hole therein may include any numbers of dies; but, the inventive concepts disclosed herein are applicable to those systems also.

The sheet C discussed herein was described as being made of cardboard, it is to be understood that the same fabrication principles may be applied to any other material that on which arcuate dies can be used.

Also in the preferred embodiment of the adjustable dies 10, ll, 12 and 13, the depth of the box, that is, the distance from the line of indentation 16 to the edge 16a of the cardboard sheet C is constant since it is determined by the position of the cutting and scoring blades which are mounted on the dies themselves. Certainly, in embodiments of this invention, even the depth of the boxes produced may be adjustable.
