[EN- amaa -nmmansQ 66 ml 68 I5 5 ///l/\ 6 g 34' 2a Inventor 34 Mar/nus Van Brurnme/en Patented Dec. 7, 1948 UNITED STATES PATENT v OFF-ICE 6 Claims. 1

This invention relates generally to box making vmachines, and more particularly to a box blank rating individual box blanks from a plurality of such blanks stacked on a rack.

A primary object of this invention is to overcome the tendency of the boxes to catch on each other and to jam, as these boxes are moved from a rack onto a conveyor in conventional machines usedin the box making industry, particularly to overcome the tendency of boxes having slits or windows to jam when an end of a box blank contacts the edge of the slits or window openings in another blank.

Anotehr salient object of this invention is to provide a rotary separator having an anti-frictional member adapted to project through the window opening of such a blank, shifting the outermost blank from a plurality thereof stacked a rack, and bearing against the underlying blank to prevent the same from shifting from the rack.

Still another object of this invention is to provide a rotary separator with a plurality of arms, and means to render one or more of these arms inoperative. When two of these arms are provided, rendering of one of the arms inoperative will halve the rate at which the blanks are fed, when the device is turned at the same rotational speed.

Still another object of this invention is to provide means for a device of this character to prevent the blank contacting members from'moving rapidly relative to the rotating disk whereon they are supported, this feature preventing vibration and erratic action of the separator.

And a last object to be specifically mentioned is to provide a device of this character which is relatively inexpensive and practicable to manufacture, extremely simple to adjust and use, and which will give generally efi'icient and durable service.

With these objects definitely in view, this invention resides in certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail in this specification, particularly pointed out in the appended claims, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Fig. 1 is a top plan view of the separator mounted on a drive shaft, together with a rack and a plurality of box blanks having windows therein and stacked on this rack;

Figure 2 is a side elevational view of the structure shown in Figure 1 and also including a frag- 2 mentary portion of a conveyor positioned to receive the blanks as they are fed from the rack;

Figure 3 is another side elevational view of the assembled separator, the view being taken from the side opposite to the side illustrated in Figure 2;

Figure 4 is a vertical transverse sectional view ofthe separator, taken on the line 4-4 in Figure 3 and in the direction of the arrows; and,

Figure 5 is a sideelevational view of the disk used to mount the arm portions of the separator, portion-3 of the disk being broken away and the underlying portions shown in section and elevation to illustrate how the two halves of the disk are connected.

Similar characters'of reference designate similar or identical parts and portions throughout for use in feeding box blanks which are apertured or windowed as at E6 and these blanks will ordinarily be fed outwardly from the leading edge id of the rack onto a conveyor 20. It will be understood that the blanks i i may be in any one of many stages of manufacture, the windows l6 having already been formed therein, and that the same blanks will be transmitted by a conveyor 2d or some analogous structure to be operated upon, as in the application of adhesive or the application of Cellophane coverings for the window it.

The disk, generally indicated by the numeral 22 in Figure 5, is constructed in two parts 2 and 28, the part 26 having secured therein aligning pins 28 and the part 24 having-bores adapted to register with and to receive the ends of these aligning pins. Elongated studs.3fi are inserted through suitable bores formed in the part 26 and are threadingly engaged in aligning bores which are threaded in the part 25, thus facilitating the attachment of the disk to the drive shaft Hi. It

' will be understood that conventional means such as splines or keys may be added to assure rigid.

connection of the disk 22 on this shaft. Each of the parts of the disk are provided with transversely disposed arcuate slots 32' for the purpose hereinafter made abundantly clear. The rocker arm it, preferably of slightly s-shape is provided 3 in duplicate and pivoted to the disk by bolts 88 which may have incorporated therewith any suitable bearing structure, these bolts 36 being threadingly engaged in bores tapped and threaded in the disk 22, It should be noted that one of the rocker arms, that designated as St is formed with an aperture 38 and an adjacent portion of the disk is apertured as at 40, so that the arm may be moved into what is hereinafter referred to as the retracted position and retained in this position 'by inserting a bolt through the apertures 38 and 30, one of these apertures being preferably threaded to facilitate the securem-ent of this attaching bolt in place. If preferred, this attaching bolt may be carried on the disk by tightly threading the same therein, as indicated at 52 in Figure 3 One end of each arm 36 and 36' is provided with a transversely disposed journal member M and a bearing member 4'5 whereby a roller 58 is freely rotatably mounted. The other end of each arm is provided with a pin 50 rigidly secured therein and extending in both directions from the arm, the portion thereof extending toward the disk 22 being accommodated by the slot 32 and carrying the sleeve bearing 52. A spring 5 3 is terminally secured to the pin 58 and to a bolt 56, so as to bias the rocker arm in one direction. The other end of the pin 59 is pivotally secured, as at 58, to the outer end of the piston rod 65. This piston rod 60 is connected to a piston 62 comprising a metal washer and a flexible washer and adapted to reciprocate within the cylinder 6%. The disk E l is provided with a projecting lug 5B which is apertured to receive a pivotal attaching screw 68 threadedly engaged in the disk 22 and provided with a lock nut it and a spacer sleeve 52. The structure detailed above comprises a substantially conventional dash pot which may be generally indicated by the numeral 76, and it will be understood further that a suitable cap 16 will be threadedly engaged on the outer end of the cylinder 6d and that the base of the cylinder (i l will be provided with a very small aperture 18 in conventional manner. It will be understood that the spring structure and the dash pot structure is in duplicate and Similarly associated with the arms 3t and 3d.

The operation of this invention will be clearly understood from the foregoing description of the mechanical details thereof, taken in connection with the above recitation of the objects sought to be achieved by this invention. In recapitulation, the rollers 48 are consecutively brought into contact with the blanks M, a portion of the roller passing through the window it in the blank and bearing upon the blank underlying that blank which is shifted by the roller Q8. The Figure 2 clearly shows the main principle of operation of this invention, since this figure illustrates how the roller will prevent the underlying blank from moving away from the rack i2. Each of the rollers 43 is dimensionally adapted,. as to width and diameter, for partial entrance into, and frictional engagement with the edge of a window 16 in the outermost of a stack of blanks M, during the operation of the device. The roller will have rolling friction only with the immediately succeeding and underlying blank, while more forcefully engaging and shifting the outermost blank. Although the dimensioning of the roller and other portions of this invention is critical, it is believed that those skilled in the art to which this invention appertains will be enabled to construct and to use a machine according to this dinventicn and this disclosure of the invention, without the inclusion in this disclosure of the specific dimensions of the various parts. The device is so constructed that exacting adjustment of the biasing means for the arms is not required, and substitution of diflferent springs 66 may be used to adjust the device when required, it being obvious that many suitable means may be incorporated with these springs to make the same adjustable and that such minor modifications of this invention fall within the spirit and scope thereof. It is also within the scope of this invention to substitute means differing from the roller structure illustrated in the drawings and though there has been shown a particular embodiment of this invention, this application is not limited to this particular embodiment, but it is desired to include in the scope of this invention the construction, combination and arrangement of parts and portions substantially as set forth in the appended claims.
