SLOTTING AND SCORING MACHINE.
Application filed November 5, 1926. Serial No. 146,310.
. The invention relates to a machine for forming slots and scores in blanks, for example, as-used in the manufacture of fibrous or corrugated paper board boxes. In the 5 manufacture of boxes of the above nature.
if a aper board of any substantial thickness be employed, it is necessary that the slots be of a width at least about e ual to the thickness of the board, and it 1s also necessary that the scores extend between the slots; that is to say, if the scores are located out of alinement with the slots, the blank will not fold properly into square box form. Usually it is desired to have the scores subslots.
Rotary slotting and scoring machines have been employed for the above purposes having male and female slotting heads, the male slotting head being provided with sectorlike blades cooperating with grooves in the female slotting head to cut out the slots, and being provided with scoring disks to form the scores. Since a box-makeris usuall required to produce boxes of various heights and widths, machines of the above type should be easily and rapidly adjustable to vary the relative angular positions of the blades on the slotting heads which cut out the slots, so as to alter the height of the box; and should also be easily and rapidly adjustable to vary the axial distances between adjacent. slotting and scoring units, thus altering the width of the box. In the latter operation it, furthermore, is very desirable that the scoring units be automatically kept in alinement with their corresponding slotting units, in order to insure that in all settings the proper alinement between the slots and scores will be maintained.
The present invention aims to provide a machine of the above type which w1ll satisfy all commercial requirements for forming proper slots and scores, insuring alinement between the slots and scores in different settings and nevertheless be much simplified as to number of parts'required, cost of construction and also be much easier and simpler to operate and adjust.
Further objects and advantages of the invention will be in part obvious and in part specifically pointed out in the description hereinafter contained which, taken in conjunction with the accompanying drawings,
stantially exactly in the center line ofthe discloses certain preferred embodiments thereof. Such embodiments, however, are to be considered as merely illustrative of its principles. In the drawings- 'Fig. 1 is a transverse sectional view, showing a pair of slotting heads and associated parts which are constructed to operate in accordance with the invention.
2 is a side view (with certain parts cut away for clearness) of the structure shown in Fig. 1.
Fig. 3 is a fragmentary view similar to Fig. 1 but showing a somewhat modified form of the invention.
In the drawings, I have not illustrated a slotting machine as a whole since the machine may be considered as having any suitable bed or table for receiving the blanks to be operated upon, together with any suitable means for feeding the blanks to the slotti heads in proper timed relation to the rotation of the latter, etc., for example as outlined in United States Patent No. 1,493,404 issued to Joshua Wagner and myself on January 4, 1923, the shafts 1 and 2 of the present application corresponding in a general way to the shafts 30 and 26 respectively of the above patent. The female slotting head 3 of the present application also may be constructed in a general way similar to the lower slotting head of the above patent, being provided, for example, with annular female slotting dies 4 and 5 which are spaced apart to provide a peripheral groove 6 in the female slotting die. As shown, the female slotting die is provided with a detachable annular side piece 7 in which the die 5 is received, and an annular stripper member 8 is carried in the groove 6 of the female slotting head to eject the paper out out in forming the slots as herelnafter described. As shown, the stripper member is slidably engaged with a fixed rod 9 which latter may be connected to the frame ofthe machine. Thus when the female slotting head is moved axially of its shaft 2, in adjusting the machine to operate upon blanks of diflferent widths, the stripper member 8 will automatically slide along with it. The complete machine will also be understood as usually provided with three or more sets of slotting heads and stripper members, all of the construction herein described.
The present invention aims primarily to provide a machine wherein the, formation slots of proper width, and scores in proper alinement with the slots, as well as a simple and quick adjustment of the machine to different sized box blanks while automatically maintaining the slots and scores in proper relation to each other, may be accomplished by slotting and scoringelements directly associated with the male slotting head. In accordance with the invention, the slotting blades are constructed and supported to overlie or overhang the scoring member and one slotting blade is angularly adjustable with regard to the other; thus when the angular adjustment is made the part of the scoring member which previously was covered by the slotting blade becomes exposed and performs its scoring function. In other words, the effective length of the scoring member is automatically correspondingly adjusted whenever the scoring blades are set, without requiring a separate adjusting operation for the scoring member. Since the slotting blades overlie the scoring member the slots also will be formed in alinement with the scores. It will be understood, however, that the alinement above referred to need not be such that the center line of the scores correspond exactly with the center lines of the slots, so long as the scores are not located wholly outside of the space between the slots, and the word alinement as used in the claims hereof, is to be construed as including variations in the position of the scores, within the above limits.-
For example, in the form of the invention illustrated in Figs. 1 and 2, the male slotting head 10 is provided with a creasing member made up of juxtaposed arcuate sections 11 and 12, the section 11 having in serted therein a slotting blade 13 which, in the position shown in the drawings, is engaging in the groove 6 of the female slotting head during the operation of cutting a slot. As illustrated in Figs. 1 and 2 the width of the active portions of the slotting blade 13 is equal to the combined thickness of the scorer sections 11 and 12 so that the blade overlies the beveled periphery of scorer section 12, while the inner portion of the blade 13 is cut away or made thinner so as to accommodate the scorer section 12. The slot; ting blade 13 is also shown in Fig. 2 as inserted in aga in the scorer section,11 and as provided wit holes 14 to receive pins 15.
The remaining scorer section 12 is shown as supported in an annular side piece 16, and a second slotting blade 17 is similarly associatd with scorer section 12, said blade 17 having its active portion overlying the beveled periphery of creaser section 11, and its inner portion cut away to receive creaser section 11. In angularly adjusting one of the slotting blades, its corresponding scorer section will move with it, and the remaining scorer section will be exposed, except as to the particular parts thereof which the slotting blade overlies in any particular angular position, and thus the proper length of scorer is always present between the slotting blades in all angular positions of the latter. In the form of the invention shown in Figs. 1 and 2, the slotting blade 17 may be angularly adjusted by loosening the bolts 18 which extend through arcuate slots 19 in side piece 16 and are bottomed in the main body of the male slotting head; it being possible to turn the side piece 16 and therefore the scorer section 12 and slotting blades 17 associated therewith, when these bolts are loosened. Ordinarily it will not be necessary to adjust the angular position,of the slotting blade 13, the latter being timed in relation to whatever feeding mechanism is employed for advancing the blanks, so as to begin to cut the first slot in the blank at the proper point. I
In the operation of the machine the blank to be slotted and scored will be fed in-between the two slotting heads by any suitable mechanism and they blades 13 and 17 will coact with groove 6 to cut slots in the forward and rear edges of the blank, forcing the strips thus cut out into groove 6 from whence such strips will be ejected by stripper member 8. The portions of the scoring member which are exposed between blades 13and 17 in themeantime will form a score between the slots, the groove 6 ofthe female slotting head also cooperating in the performance of the scoring function. In some instances the slotting heads may engage the blank so as to act as feeding rollers in advancing the blank past the head, or the blank may be fed through independent of any feed-roller action by the slotting heads.
In adjusting the slotting heads axially of shafts 1 and 2 to operate on box blanks of different widths, one of the slotting blades 13 or 17 will be engaged with the roove 6 of the female slotting head, after w ich the slotting heads may be loosened on their respective shafts 1 and 2 and slid along together either by hand or by any suitable force-applying mechanism, thereby adjusting both the slotting'and scoring elements in a unified movement.
A machine of the above type involves a substantially reduced number of parts as compared to prior machines which are capable of roducing properly slotted and scored blanks and of being'adjusted to suit different dimensions of blanks without requiring that the machine be taken apart. The machine is also very simple in regard to the adjustments necessary to be made in setting it for blanks of different dimensions.
In Fig. 3 I have illustrated in a general way another embodiment of the invention wherein a female slotting head 2 is provided with a peripheral groove 6 and a male slotting head 3 is provided with a fixed scoring ringll which forms a complete circle. A sector-like slotting blade 13 overlies the scoring ring and has its inner portion cut away to receive the scoring ring, the slotting blade being held in position by suitable ad ustable clamping devices, such as the bolts 18. In this instance the slots will be quite a little wider than the scores which is not objectionable for some purposes, and angular adjustment of the slotting blade may be made merely by loosening up the bolts 18 and moving the blade itself around to the desired posit-ion, the adjustment being usually indicated by suitable calibrations upon the periphery of the slotting head, in machines of this nature.
