' DELIVERY MECHANISM non BOX-FILLING MACHINES;

Application filed ,April 22, 1926. Serial No. 103,674.

This invention relates to box filling ma chines, and more especially to machines for filling match boxes of the tray and shuck' conveyer for transporting complementary trays and shucks, means for filling the trays with matches, and means for insertingthe filled trays in their shucks. The filled and closed boxes are advancedby the conveyer to a position'where they are discharged from the conveyerby gravity down an inclined chute leading to a suitable receiving table.

The object of the present invention is to provide a simple and eflicient mechanism whereby the boxes as rapidly as they are discharged from the conveyer are transported thence to, and are arrangedin an orderly manner in, a receiving element from which they may be manually removed in predetermined quantities for wrapping or be transferred to a. wrapping machine.

Accordingly, the invention comprises novel features of construction and combinations of parts which will be hereinafter describedand claimed.

Referring to the drawings, lOdesignates a part of the main frame, and 11 a partof the main drive shaft of a machine for filling trays with matches and associating the filled trays with their complementary shucks or covers. 12 designates the delivery end of a continuously driven tray and shuck conveyer, the upper longitudinal run whereof is arplementarycovers on the conveyer12. The

ranged to travel along a bedor table 13 sup- I V ported by the frame. This conveyer preferably comprises a chain of links having o'ut Wardly projecting blade-like members 14:, 15 60..

which are relatively arranged to afford a sue-c cession of. aligning holders for complementary trays and shucks. The conveyer passes about suitably-located sprocket wheels at the respective ends of. the table,.one of which wheelsiis shown at 16 fast on a shaft 16 to the main shaft, as, for example, by the cam 160 and pin wheel 161 fast. on the shaftsllj. and 16' respectively. v y Located at one side of the'conveyer 12is a second continuously moving conveyer' 17 comprising preferably a chain of box-like links suitably provided with. reciprocating transverse plungers 18 havingrolls 19 which travel in, an appropriate stationary cam-way 20 and are thereby actuated to reciprocate the plungers, which latter intheir; inward strokes pushtherfilled trays into their complunger conveyer 17 passes'about suitablyall as fullyset forth in Patent No. 1,300,7 62

aforesaid. I a

Mounted below and rearwardly of the discharging end of the convever 12 is av delivery element comprising in. its preferred construction a'wheel 22 having spaced periph- H eral ribs forming pockets 23 whichmare adapted inthe rotation of the wheel to reg-, ister with the shuck holders insuccession 24 is equipped. with a gear, 26 in mesh with 1 a similar gear 27 on' the driven shaft. 16', whereby the delivery wheel is rotated at the same surface speed as the conveyer 12;.

This wheel is equippedwith radially mov-: able plungers 28 which enter the respective g pockets and are provided with expanded end portions 29 which afford, in eflect, movable bottoms for the pockets. Fixed to the main frame, at one side of the wheel 22, is a I 1, 21,301. ur ;F 1cE.-;

which motion is suitably transmitted from i 80... located sprocketwheels. one of which is I and receive therefrom the filledandclosed 1 boxes discharged from the conveyer 12. :The wheel 22 is'faston a shaft 24. having its: hearings in suitable brackets 25 supported- "bythe main frame. ,One end of the shaft .and are supported y ,30

face cam B0 in the trace of which run {lat-- centric portion 32 of the cam race, so as gradually to retract the lungers 28 in succession as they progress to the initial end of the concentric portion.

'Wheneach succeeding box is' discharged from ,the conveyer '12 ,into a pocket of .the

delivery wheel, "the latter carries the box therewith while the roll of the plunger is traversing the concentric cam portion 32; The succession of boxes thus introduced in and'carried by the wheel are maintained in placeby means of a guard comprising segmental fr oinithe pocketed appropriate "

brackets

36, 37. on the main frame.

niin'atesiin the vicinity of the outward lead 33 ofthe cam race, and is connected to a 7 suitable receivingelement comprising, in the presenti-nsta-nce, an upwardly inclined takeoff trough 38 which is supported by the adjacent bracket 36.' As each succeeding box, in the rotation of the delivery wheel, clears the guard, the roll of the plunger whichis associated with the pocket in which the box 'is seated, escapes the concentric portion 32 of the ca m race and the plunger is t hereupon immediately projected outward by the action of a reciprocating ejecting "member '39 with "which the roll of the plunger co-acts at this stage, the plunger thus forcing the opposing box to and upon the take off trough, as'seen in Fig; 3.- The member 39 preferably comprises ahead formed on an angular arm 40 atthe upper end of a lever which is fulcru medat its lower end on a stud 42 projecting from the outer face of the cam body 30. The wall of this cam body is formed with an enlarged opening 453 through which the angular a-rm extends so as to support the head 39 adjacent the outward lead of the cam race, the inner wall of the latter beingcut,

away, as at 44, to permit the head to be swung into and from the race. The head is-maintained normally with its acting face if Within :the cam race means of a stout spring-145 which is interposed between the head and'a *fixed depending portion 46 within the cam body, such :face being inclined, as. at 457, from a point below the cam porsections 3.5 which are suitably spaced eriphery of the wheel The guard ter- 7 tion 33 to a pointwithin .the same and above "the opposing box .to the take-01f trough 38,

as previously described. The inclined face of the head is engaged by the rolls 31 of the respective plungers in succession, during the rotation of the wheel, and in consequence a' rapid and uniform delivery-of the boxes to the take-off trougn is accomplished. I

As each succeeding plunger roll escapes the head 39,1the roll enters the cam ,por-' tion and passes thence to the concentric portion 32 of the cam race, at which period the plunger is retracted to permit the entry of another box in the ivheeh Arranged at the sides of the receigving end of the trough are a pair of flared spring plates 48 which depend below the trough and are positioned to embrace and bear yieldingly against the ends of each box as it approaches and reaches the .end of the take-oil trough. These plates are preferably supported by a pair of spring strips i9 which are secured to the respective side walls of the trough. The resilient plates by their action against the ends of the box keep the latter in a central position relative to the trough preparatory to'the entry of the upper corner of theincoming box passes the lower corner of the box previously entered in the take-0d trough, before the plates have been suflieiently spread apart to allow the passage of the incoming box to the trough; and the upper ends of the plates4-8 extend slightly above the side walls of-the troughand support on their inner sides inclined bars 50 which are so disposed. as partially to overhang the ends of the upper side of thebox and thus prevent its beingaccidentally carried upward from the trough by i the projected plunger during the upward travel of the latter.

From the foregoing it will be seen :that a inechanismis provided whereby theboxes as rapidly as they are discharged from the traveling conveyer 12 of the l-iillingmachine enter the successive pockets of the rotating delivery wheeland are advanced thereby to a location Where they are succesively introduced in the take-0E trough in an orderly row from which predetermined quantities of the boxes can be manually removed for wrapping or be transferred to a wrapping machine.
