WASTE EJECTOR FOR BOX-BLANKING MACHINES.

Application filed November 30, 1927. Serial No. 236,616.

The invention relates to machines for blanking out boxes, more particularly boxes made of heavy paper such as the double-faced corrugated paper board now in general use for such purposes, the blanking machine 1nvolving cooperating rotary male and female slotting heads which cut slots in the blank, leaving waste chips in the groove of the female slotting head which must be ejected therefrom.

llhe primary object of the present invention is to provide a waste ejector for machines of the above type which will be exceedingly simple and reliable in construction and operation, and which may be automatically adj usted along wit-h the corresponding slotting heads and scoring members, whenever the machine is set to operate on blanks of different widths, without requiring extra sliding connections or supporting parts to be included in the machine for the waste ejector.

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, discloses a preferred embodiment of the invention; such embodiment however is to be considered as merely illustrative of its principles. In the drawings- Fig. 1 is a vertical sectional view showing a waste ejector constructed in accordance with the invention. In operative relation to the slotting heads and scoring members of a rotary slotting and scoring machine.

Fig. 2 is a detail view of the parts making up the waste ejector hereinafter described.

The slotting and scoring mechanism of the machine may be of known type, involving for example a male slotting head 1 supported by and rotating with a shaft 2, and having a pair of sector-like slotting blades 3 which run in a peripheral groove 4 of a cooperating fe male slotting head 5 supported by and rolating with a shaft 6.

A suitable scoring member also will usually be employed consisting for example of a rotating disk 7, carried by shaft 8 and pressing the blank against some suitable surface such as roll 9, the paper blank being first fed between the scoring member 7 and roll 9 to form a crease or score therein, and then fed between the male and female slotting dies 1 and 5, to form slots at the opposite ends of the crease. The complete machine will also be understood as usually provided with three or more sets of slotting heads and scoring members as above described, and suitable means for feeding the blanks thereto in proper timed relation, which features of the machine it is not deemed necessary to describe in detail herein.

In accordance with the present invention, we provide a waste ejector running in the groove 4 of the female slotting head, which is held in proper position by the corresponding scoring member, such waste ejector being preferably of annular form and supported by the female slotting head, so that it entails the use of no added parts on the machine to hold it in place. For example, the waste ejector shown in the drawings has an annular body portion 10 which runs in the groove 4 of the female slotting head, and is supported by the latter, and said waste ejector is also provided with a concave portion 11 which is adapted to bear against creasing member 7 to hold the waste ejector in proper position, that is, prevent it from turning around with the female slotting head.

The invention has special advantages in connection with slotting and scoring machines of the quick-set type, that is in which the slotting and creasing members are interlocked so as to be simultaneously axially adjustable in setting the machine to operate upon blanks of Varying widths. As shown, the creasing member 7 also projects into the groove 4, of the female slotting head whereby when one of the slotting blades 3 of the male slotting head also engages in such groove, the slotting, scoring and waste ejecting elements are all interlocked so as to maintain proper alinement in setting the machine It will be noted furthermore that all extra parts for supporting the waste ejector so as to permit it to slide along when the n'lachine is adjusted, or to hold it in proper operative position, are eliminated.

To facilitate setting the slotting and scoring members axially for blanking out boxes of different widths and thicknesses, suitable means may be employed such as a bar hav ing a handle 12 adapted to fit in notches 13 of an angle bar 14; extending alon: of the machine, the branches 15 of t being adapted to bear against the hubs of the slotting heads 1 and 5, whereby as the b r is rocked with one of the blades in t. ment with the groove 4 of the female slotting ejector,

head and that it ejects the chips further under the machine than is the 'case with fingers as heretofore used for such purposes which usually have'thrown the chips out the back of the machine where they may fall in between the completed blanks. For convenience in assembling, the waste ejector may be made in two parts with overlapping ends 17 provided with screw holes to enable the parts to be fastened together when placed in the groove of the female slotting head.

While a speclfic embodiment of the invention has been disclosed it will be obvious that many chan es may be made therein without departing from its principles as set forth in the appended claims.

We claim 1. In a box making machine, a rotary female slotting head having a peripheral roove therein, a rotary male slotting head aving one or more blades adapted to project into said groove, a scoring member positioned at one side of the female slotting head, and a waste ejector acting in the groove of the female slotting head, said waste ejector being interposed between the scorin member and the bottom of the groove and liaving a part engageable with the scoring member to prevent rotation of said waste ejector.

2; In a box making machine, a female'slotting head, having a peripheral groove therein, a male slotting head having one or more blades adapted to project into said groove, a a scoring member positioned at one side of the female slotting head and a waste ejector acting in the groove of the female slotting head and held in position by said scoring member.

3. In a box making machine, a female slotting head having a peripheral groove therein, a male slotting head having one or more blades adapted to project into said groove, a scoring member ositioned at one side of the female slotting ead and an annular waste ejector acting in the groove of the female slotting head, said scoring'member also ongaging in said groove.

4. In a box making machine, a female slotting head having a peripheral groove therein, a male slotting head having one or more blades adapted to project into said groove, a scoring member positioned at one side of the female slotting head and an annular waste ejector acting in the groove of the female slotting head, means being provided to prevent rotation of said waste ejector.

5. In a box making machine, a female slotting head having a peripheral groove therein, a male slotting head having one or more blades adapted to project into said groove, a scoring member positioned laterally of the female slotting head, said scoring member engagingin the groove of the female slotting head, and a waste ejector also acting in said groove, said waste ejector being supported by the female slotting head.

'6. In a box making machine, a female slotting head having a peripheral groove therein, a male slotting head having one or more blades adapted to project into said groove, a scoring member positioned at one side of the female slotting head, and a waste ejector acting in the groove of the female slotting head, said waste ejector having a concave portion adapted to engage against the periphery of the scoring member.

.7. In a box making machine, a female slotting head having a peripheral groove therein, a male slotting head having one or more blades adapted to project into said groove, and a wasteejector acting in said groove, said waste ejector being supported by the female slotting head, whereby the waste ejector Wlll move axially with said female slotting head when the latter is shifted.

8. In a box making machine, a rotary female slotting head having a peripheral groove therein, a rotary male slotting head having one or more blades adapted to project into said groove and an annular waste ejector carried by the female slotting head in said groove and projecting outwardly from the groove at one or more points, means being provided to prevent said waste ejector from rotating with the female slotting head.

In witness whereof we have hereunto set our hands this 25th day of November, 1927.
