Specification of Letters Patent.
Patented Oct. 15, 1918.
Application led November 24, 1917. Serial No. 203,706.
To all whom t may concern:
Be it known that we, ARVID P. EKVALL and HERMAN STARE, both citizens of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and Aof the character specified, with means for preventing disarrangement in the spaceintervals when a can is not present for regularly taking its place'in the series, and for synchronizing the timing of delivery intervals in relation to the action of the succeeding mechanisms in the afiixment of labels.
The nature, construction and mode of operation f our invention is explained in the following detailed description; the particular subject matter claimed being hereinafter definitely specified.
In the accompanying drawings, (two sheets) Figure l represents a section elevation view of our can-feeding and spacing mechanism, and such parts of a can-labeling machine as will illustrate the nature of our invention. Fig. 2 is a plan view of the same. Figs. 3, 4 and 5 represent vertical sectional views of the mechanism, showing the parts at various stages of their action. 6 is a separate detail View of the spacer devices. Fig. 7 is a vertical sectional view of the back of the spacer device, separate from other parts.
In the drawings, R indicatesthe rollway for cylindrical cans, or the like, which are delivered thereto by an inclined chute or conveyer A, of any desired length, upon i which the cans are placed manually or otherwise. The chute is preferably hinged to the ceive power and motion from any approved source. s
D indicates the overhead or top Aframe upon which the belt-pulley and feed mechanlsm are supported. In practicesaid frame4 is adjusted up or down to accommodate different sized cans. i
P indicates the yieldingly mounted presser rollers arranged across the lower run of the belts, as heretofore employed, and C- the cans in their passage in the mechanism. i
13 indicates the primary can-gummingl tating said rolls from a wheel upon the operating shaft 9; and 16 denotes the side guides between which the cans travel in their progress through the machine. E indicates the contacting member of the lapend gumming appliances, which may be of any suitable character, preferably adapted to act at uniformly timed intervals.
At a convenient position adjacent. the front of the belt-supporting pulley B+, we provide an oscillating plate or spacer element 20 arranged across the feed-delivery chute above the path of the incoming cans, and is connected `by suitable ears .2 with a transversely disposed axis-member or shaft Q1 mounted in bearings 19 upon the forward part of the overhead frame D,or'some equivalent support. The height of the spacer 20 above the surface upon which the cans C roll, is approximately equal tothe diameter of the can. The under surface of the spacer element (see Fig. 6) is preferably arched from its front to its rear edge, or made in the form of a cylindrical segment; the curvature of the arc being of equal or somewhat greater radius than the outside curvature of the largest sized cans to be operated upon. The under side of the spacer element 20 is vadapted for approximately embracing a segment of the cylindrical upper surface of the can, somewhat in the manner of a saddle, or as a can-housing member, for maintaining the can in accurate transverse relation upon fingers 1 and the pawl cated adjacent thereto, as at 26.
the. rollway; said'spacer element is tiltable or rockable for alternately elevating its front. and rear edges for admitting and releasing the can containedv thereunder. Said space-r is longitudinally stralght and arranged transverse of the rollway, parallel with the position of the can, and is provided on its upper Side at or near the rear edge with bearing lugs 3 in which there is ounted a rockable shaft 23, parallelwith the supporting shaft 21. The spacer 20, or 1ts axis shaft 21, has rigidly connected therewlthV a projecting arm 17 provided with a stud-roll 17+ that engages with a cam 2-1 arranged upon and revolving with the operating shaft 9 of the belt-carrying pulley B+. A suitably tensioned spring 7 is combined with the arm for keeping the end of the arm or lts studroll up against the cam, and for moving the spacer 20 as controlled thereby. The general shape of the cam 24 is indicated by dotted lines on Figs. 1, 3, 4 and 5.v A portion of its periphery is, 'in the present instance, formed on a circular arc-s1milar to that of the pulley B+; butit may be varied or made of larger or smaller dimension if in any 1nstance so required.
The arm 17 may be fixed or pinned upon the axis shaft 21, or attached to the spacerplate which is preferably pinned upon the shaft, so that said spacer is oscillated by movement of the arm, or in equivalent manner. Said arm, in the present instance, serves as the complement of lug 3, and has the bearing for the shaft 23 formed therein.
The lines III, IV, and V on Fig. G, indicate positions of the arm 17 corresponding to thepositions in views Figs. 3, l and 5.
In the operation: If there is no can in the feed-Way, as when starting up the machine, or if a can is absent from the approaching line in the chute, then when the swell of the cam presses down the arm 17 the pawl 5 is carried below the stud 25 andis swung by the action of the spring (i and rocking shaft 23 to a position behind the lug on stud 25, so that as the receding portion of the cam comes around the pawl engages therewith temporarily locking the fingers it in position for intercepting or arresting a later coming can when beneath the spacer 20,
and detaining it until the proper relation in action is attained. The front edge of said spacer element is lifted and its back edge depressed when the arm 17 is forced down bv the cam 24.. Fig. 3 shows the pawl at a position just before unlocking, and Fig. l is at a position after it has unlocked.
In normal running action the cans are placed in the inclined chute A. in any convenient manner, so as to roll down to the spacer mechanism in continued supply. The first can (l enters beneath the arched spacer while the front edge is elevated, and may be there detained until the spacer is oscillated rearward on its axis 21. The adjacence of the spacer element to the top of the cylindrical can requires an oscillative movement of the spacer t0 enable the can to pass beneath it. As thc reduced portion of the cam comes around it allows the spring 7 to lift the arm 17, thus raising the rear edge of the spacer and freeing the can at a prede-V termined time, so vthat the friction band 27 will positively roll the can under the propelling belts B, and depressing the front edge of said spacer to contact with, and arrest the second can C2, and those following (see Fig. 5) until the arched spacer element is oscillated to its primary receiving relation by the swell of the cam. pressingr down the arm. In like manner successive cans are individually released at spaced intervals of distance and time corresponding to the revolutions of the controlling cam, acting synchronous with other parts of the machine. i
During. the time, if any, that a can is retained by the spacer 20, the band 27 will slip on the surface of the can. The forward movement of a can is delayed only until the proper instant for its delivery, or until the preceding can has reached the predetermined interval of space therefrom.
When cans come to the spacer mechanism in an irregular manner, or with greater or.
less width of spaces between them, then if not in the exact proper spacerelation, as the front edge of the Spacer is lifted, the can may pass into contact with the fingers 4; which, under such condition, are always found-temporarily locked by the pawl 5, so that said lingers intercept and momentarily detains the can until it assumes the correct Working relation in respect to oscillating spacer; at which position the pawl becomes unlocked and the can becames released as above described; the movement of 'the can readily pressing back the fingers l which are then subject only to the slight resistance of the spring 6. By this means derangement in the space intervals is obviated, and the delivery intervals are synchronized with relation to the timing andspace intervals in the act-ion of the label-aiixing means or succeeding parts of the machine to which our invention may be applied.
We claim and desire to secure by Letters 1.
