9 Claims.

This invention relates to a device for feeding paper inserts into insets in can covers.

An object of the invention is to provide a device of simple construction which will effectively feed paper inserts into can covers.

Another object of the invention is to provide a device which is capable of operating at a high rate of speed in an economical and efiicient manner.

A further object of the invention is to provide a means of inserting advertising matter in the form of paper booklets, cards or metal discs into insets in can covers or into other articles or packages having insets in their outer surfaces.

There are various machines known to the art which are capable of performing the functions of the machine of this invention. These de vices, however, are generally of an elaborate nature, containing many moving parts which necessarily involves a high initial cost and a similar cost of operation. Moreover, these machines are capable of feeding approximately sixty inserts per minute into can covers.

Our invention is of simple construction and is capable of feeding approximately one-hundred and fifty inserts per minute into can covers or packages. The machine as here set forth performs two functions; first, a reciprocating arm engages and moves an insert from a stack, and deposits said insert upon an inset in a can cover and, secondly, a rotary inserting device then presses the insert into the inset.

The embodiment of our invention consists of a can conveyor in the form of a continuous chain l2 having equally spaced lugs l3 which form seats for the cans l4. The chain is driven over the conveyor structure l5 and a supporting table I6 by means of a gear I! driven by a shaft l8. This shaft is driven by a sprocket I9 and chain 29 from reduction gearing 2|. A motor 22 employing commercial electric current drives the reduction gearing through shaft 23 and flexible coupling 24.

An intermittent clutch 25 is driven from the reduction gearing by means of

chain

26 and 5 sprockets 21 and 28. The clutch is positioned on a shaft 29 held in bearings 30 which are mounted on standards 3|. A driving clutch disc 32 carrying a lug 33 is made integral with the sprocket 28; both members running free on shaft 29. A driven clutch disc 34 fastened to the shaft 29 has a pin 35 outwardly urged by spring 359 and controlled by a lever 36 (Fig. 4). The pin has an inset 369 at its outer extremity to provide a clearance for the lug 33 when the pin is depressed by lever 36. When the lever is withdrawn, the pin urged outwardly by the spring, contacts the lug on the driving disc. The lever is bolted to a rod 37, supported by and freely movable in a guide 38 which is positioned on the standard 3|. The lower end of the rod is bolted to an arm 39 which carries a plate 40 normally held in the path of the moving cans seated on the con veyor by a contraction spring 4| (Fig. 2).

Each can passing along the conveyor contacts the plate and moves the arm, thus imparting a rotary movement to the lever which releases the pin 35 and allows it to engage the lug 33 upon the driven disc 32. Rotary movement is thus imparted to the shaft 29 and the cam 42 which is fastened to its extremity. After the momentary contact with a can upon the conveyor, the arm is returned to its normal position by action of the spring 41. This action also places the lever in a position to receive and depress the pin 35 thus disengaging it from the lug on the driving disc. The pin has also an offset 349 in its outer surface to engage an inset 330 in the upper surface of the lever, to preclude movement of the disc when it is not being driven by the disc 32. Thus the clutch is synchronized with the moving cans so that the driven clutch disc carrying the pin and driving the cam revolves once for each can, while the driving clutch disc makes one revolution to actuate the clutch and one free revolution for each space between the cans.

A link43 is fastened in a slot 44 in the cam by means of an adjustable lug 45. The link pivotally engages an inclined finger 46 riding in an inclined groove 41 upon the inclined table 48. The 50 finger is controlled by the cam 42 and reciprocated in the groove with each actuation of the cam. A demountable knife 49 bolted to the top of the finger has an inset 5D slightly less than the thickness of one of the inserts. The reciproeating finger carries the knife in a slot 5| under the insert stacking base 52. The knife engages one of the inserts 53 from the stack and carries it through aperture 54 and deposits it upon the inset 55 in a can cover. A downwardly urged stop 56 allows but one insert to pass through the aperture 54, with each outward stroke of the finger. Preferably our stacking device consists of two vertically inclined bars positioned on the stacking base 52 (Fig. 3) and against which the inserts 53 rest. When the insert stack is nearly exhausted it is only necessary to place additional inserts upon the stack to replenish it. The insert stack can, therefore, be replenished from time to time without necessitating the stopping of the entire mechanism thus providing a continuous feed which is highly desirous in this type of machine.

The inclined position of the table 48 and the parts thereon allow an insert, engaged by the knife 49, to move downwardly in an inclined position so that the lower edge of the insert is brought close to its position in the inset of the cover of a moving can before the knife is withdrawn.

A rotary inserting means consisting of ashaft .56, a hub 51 positioned on the shaft having projecting arms 58 which carry circular cups 59 in which are. seated rubber cylinders 60 having an inset 6| in their outer faces, is positioned on standards 62. This inserting means is driven by a sprocket .63 and a chain 64 connected to shaft '18 of the conveyor mechanism. The rotary movement .of this inserting means is so synchronized with the can conveying means that each rubber cylinder contacts an insert upon a can cover.. The rotary speed is somewhat faster than .the can movement so as to allow the rubber cylinder to move the insert directly over the inset and then press the insert into the can cover.
