3 Claims.

This invention relates to an article forming machine, and more particularly to feeding mechanism for paper bottles.

Among the principal objects which the present 5 invention has in view are: To automatically control anti-jamming of parts of articles being assembled; to restrain further feeding of the duplicate parts to the one jammed; to avoid injury to the machine; to provide for ready return of 10 the machine to operation;' to make it obvious to the operator when a part is jammed; to secure simplicity of construction and operation; and to obtain other advantages and results as may be brought out in the following description.

As seen in the drawings, let it first be said that such part of a container-assembling machine as enters into the construction and operation of the particular invention herein involved has been 45 shown. Such machines provide suitable framework or bed structure 15 on which is mounted a rotating head or article carrier I6 having a plurality of holders or dies I! which are brought successively into alinement with a plunger la. The

successive dies 11 have a part of the article to be assembled inserted therein before said die comes into alinement with the plunger, and as here shown, the part 19 of the article inserted in the successive dies is the side or cylindrical 55 part of containers, such as paper milk bottles.

An instrumentality is provided for automatically positioning another part of the article, namely, the bottom 20, crosswise in front of the end of the plunger to be actuated by the plunger [8 and forced into the end of the other part 19 of the article. The present invention relates more particularly to the said instrumentality, and for convenience in the description thereof, the part of the article being fed thereby will be referred to merely as a disc, without implying any limitation as to circumferential shape, surface or other formation.

The several discs 20 are supplied in stacks as shown in Figure l, flatwise against each other in axial coincidence, with suitable pressure means, such as the weight-actuated rider 2!, for forcing the stack axially each time a disc is removed. The discs are .removed one at a time from the forward end of the stack by sliding such disc laterally from the stack. The above-mentioned instrumentality accomplishes this operation, effecting the removal of the disc from the end of the stack, a lateral transition and placement of the disc in the path of the plunger. As here shown, said instrumentality comprises a platelike guide member 22 the plane of which is normal to the axis of the stack of discs so that the forward end disc will rest fiatwise against said member near one end thereof (for convenience referred to as the upper end of the member). The said member is of a length more than two diameters of the discs, thereby enabling a disc to be moved laterally from the stack toa position at one side of the stack but still facing in the same general direction and in facial contact with said member. An imaginary center line of said member will intersect the axis of the aforementioned plunger It. The parts are so arranged that the axis of the stack and the axis of the plunger are parallel and spaced from each other more than a distance of one diameter of the discs 20. Thus there will be no overlapping of the discs remaining in the stack and the end disc which is moved laterally to its new position in axial coincidence with the plunger.

As shown, for instance in Figures '7 to 11, the said plate-like guide member 22 is provided with a foot 23 thereon by which said member is mounted in stationary position upon the bed 15 of the machine. The opposite faces of said memher are recessed longitudinally to provide the track construction. Noting particularly Figure '7, it will be observed the member provides side or marginal ribs 2 5 of a depth substantially that of the thickness of a disc 20 to be fed. On the other ill or outer side of said member are edge or marginal under-cut ribs for receiving and retaining a plate-like positively actuated slide 26 forming a part of what may be termed the actuator 21. This actuator also includes as part thereof a plate-like releasable slide 28 parallel to the said positively actuated slide 26, spaced therefrom by the intervening thickness of the guide member 22 and both said slides being fiatwise slidable upon the opposite faces of the intervening part of said member. In normal operation, both said slides reciprocate simultaneously. Both said slides are provided with disc openings, the inner or releasable slide having an opening substantially the diameter of the disc for an upper semi-circumference, and therebelow extending to the end of the slide. The outer or positively actuated slide is shown with an opening somewhat more than the diameter of the disc for an upper semi-circumference, and therebelow extending to the end of the slide. This larger size of opening in the outer slide is to pass the disc therethrough without any engagement of it en route. The opening in the inner or releasable slide is for purposes of receiving the end disc with a measure of accuracy and pushing it downward in the guide member. The open end for this opening permits the slide to retract to its upper position and leave the disc in the lower position to which it has been pushed.

Means are provided for obtaining a releasable actuation of the disc-engaging or inner slide 28, so that in event a disc becomes jammed, as illustrated in Figure 10, the positive actuation of the outer slide 26 is not communicated to the inner slide until the fault has been corrected by the operator. For this purpose, the upper end of the positively actuated slide is shown provided with a cross-head thereon consisting of a filler bar 29 between the two slides extending cross-wise of the slides, and a parallel yoke 33 extending across the inner face of the releasable slide. As clearly shown in Figure 6, this yoke is provided with holes 3| directed toward the slide, and in these holes, at their ends next the slides, are balls or other engaging means 32 pressed toward the slide by springs 33 in the holes in turn adjustably tensioned by screws 34 protruding from the outer ends of the holes. The slide is conveniently pro vided with depressions into which the balls or the like will snap while the slides are in normal position and operation, the depressions, with the holes and spring tension affording the requisite frictional engagement for actuating the releasable slide from actuation of the positively actuated slide. However, should a disc jam, the releasable slide encounters enough additional resistance thereby to effect release of the frictional engagement, and thereupon remains quiet even though the positively actuated slide continues to reciprocate. The upper end of the inner slide therefore remains outward, and the operator readily notices it, and can stop the machine to overcome the difiiculty.

I have discovered that one outstanding cause for jamming of the machine arises from failure of the discs to properly enter the opening in the releasable slide 28. I have overcome this problem by reducing to a minimum the edge engagement of the discs with the fixed support thereof where passing the guide, and particularly at the part of the perimeter of the disc at the front thereof when slid. As shown, I provide a face plate 35 which is positioned flatwise of the guide between the inner or releasable slide 28 and the stack feed. This plate has an opening 36 for passing the disc therethrough, and a lower opening 31 through which the plunger l8 may pass. The upper opening 36 has its upper half curved substantially on a semi-circle, the center for which is coincident with the axis of the stack. Its lower half is upon a semi-circle or otherwise, to off-set the same from coincidence with the disc perimeter thereat. From this lower enlarged opening edge, in the plane of the face plate, project two spaced retainers 38 directed in a radial direction with respect to the opening and projecting to substantially a distance to lie upon a theoretical continuation, shown by dot and dash line 39, of the semi-circular upper opening upon the same center of curvature. The end disc is thus fed through this face plate in contact with the upper semi-circular part of the opening of the plate and having a lower contact only with the ends of said retainers 38. This limited engagement not only augments the action to pass the disc into the slide opening, but renders it both possible and probable that the disc, if still engaged partly upon the retainers when the down-, stroke of the slide begins, will snap off of-the retainers into proper position in the slide opening. Reciprocation of the positively actuated slide 26 is effected by a crank arm 40 having a slot 4| longitudinally thereof taking over a stud 42 on the slide. The other end of said arm is fast upon a yoke 43 rotatably mounted on a shaft 44. The opposite end of the yoke is fast with respect to a clutch member 45 in turn engageable by a cooperating clutch member 46 splined upon said shaft so as to rotate therewith but slidable for permitting the clutch function to be performed. Shaft 44 is continuously rocked in synchronism with the rest of the machine elements through an arm 41 connected at its end and in turn shown connected to a link 48 carried by a rider 49 in turn operated by a cam 50. (See Figure 3.) Clutch member 46 is shown as automatically operated by a solenoid 5|, the core 52 of which is longitudinally movable and connected to a clutch operating lever 53. The electrical terminals of the solenoid complete a suitable circuit from a source of potential, such as battery 54 indicated, and through a switch 55 the closing of which is obtained by engagement of a part of the switch with the part of the article I!) carried by the rotating die l1. 1 In the event an article is present, the switch is closed, the clutch is thrown in and the slide is thereupon actuated to place a disc in its position in front of the plunger l8. Thereafter the forward movement of the plunger inserts the disc through the female die, forming the disc into the desired cupped end and inserting it into the said part of the article engaged by the switch. Consequently, in the absence of a part of the article in any one of the dies of the rotating carrier, no disc is lowered to the plunger and the plunger merely operates idly for that particular reciprocation.

I claim: 1. An article assembly machine instrumentality for removing discs and the like from a stack, comprising a slide for engaging the forward .disc edgewise and moving it laterally, said disc passing to said slide through an opening of greater size than said disc in the direction of sliding of the disc. 2. An article assembly machine instrumentality for removing discs and the like from a stack, comprising a slide for engaging the forward disc edgewise and moving it laterally, said disc passing to said slide through an opening of greater size than said disc in the direction of sliding of the disc, and radial retainers in said opening ex tending inwardly of the opening substantially to an equal distance to the center of curvature of 5 the opposite part of the opening.
