This invention pertains to sheet feeding and delivery apparatus, and more particularly to means for progressively depositing in vertical positions a rapid succession of individual cards or sheets and automatically assembling them, side by side, into compact formation.

While the invention is particularly useful in assembling multiple printed sheets or cards as they leave a writing or imprinting apparatus or web severing or bursting machine, it is not necessarily limited thereto but may be utilized for assembly of metallic or plastic sheets or manufactured articles as they come from a stamping press, blanking machine or other forming apparatus.

For illustrative purposes, but with no intent to unduly limit or restrict the application or score of the invention it is herein especially described as for use in conjunction with strip feeding and imprinting apparatus, such as disclosed in patents to Sherman No. 2,172,414 and No. 2,177,675 and with web severing and bursting machines of the type illustrated in patents to Metzner, No. 2,252,- 720, Sherman et al. No. 2,252,733 and Zent No. 2,355,690, but obviously is not limited thereto.

The object of the invention is to improve the structure as well as the means and mode of operation of sheet delivery and assembly apparatus, whereby it may not only be economically manufactured but will be more eflicient in use, automatic in operation, uniform in action, having relatively few operating parts, and be unlikely to get out of repair.

A further object of the invention is to provide an apparatus which is adjustable for operation upon cards or sheets of different sizes and for depositing a rapid succession of cards in upright positions and for assembling the vertical cards into a compact packet.

A further object of the invention is to provide an apparatus of the character mentioned possessing the advantageous structural features, the inherent meritorious characteristics, and the mode of operation, herein described, or their equivalents.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to 'be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described or illustrated in the accompanying drawings.

In the accompanying drawings, wherein is illustrated the preferred, but obviously not nec- 15 Claims. (Cl. 271-87) 2 essarily the only form of embodiment of the invention,

Fig. 6 is a detail view of one of the feeding rollers, in relation to the trip and card pushing arms.

Like parts are indicated by similar characters of reference throughout the several views.

The present sheet feeding and delivery unit is employed in sequence with a writing, imprinting, severing or bursting machine, stamping or forming press or other production unit by which a series of separate sheets or cards |--l are supplied to the instant unit in rapid succession, and from which the present unit derives its motive power. The succession of individual sheets or cards l--l comprising the output of the preceding unit enter the apparatus over a guide table 2, and between a pair of feed rollers hereafter identified.

At the top of the unit is a drive shaft 3, which may be a driven shaft of the preceding supply unit of which it may constitute a delivery shaft, which progressively ejects the sheets or cards l-I, for which purpose the shaft 3 is shown provided with a series of knurled collars d-4.

The drive shaft 3 carries at its extremity a gear wheel 5 which meshes with a gear pinion 6 journaled on a stud I projecting inwardly from the side 8 of the main frame of the unit. Connected with the pinion 6 for unison rotation on the stud 1 is a sprocket wheel 9 by which an endless chain belt I0 is driven. The incoming sheets or cards l--l pass between a pair of feed rollers H and I2. The former carries a sprocket wheel driven by the chain belt Hi. The latter comprises a series of knurled collars peripherally engaging with the larger roller H to frictionally advance the sheets or cards I received from the preceding machine. The sheets or cards l-l are advanced by the rollers H and I2 over .the guide table 2 to a succeeding group of feed rollers l3, l4 and IS. The roller l3 preferably comprises a series of axially arranged relatively spaced sections, having narrow spaces therebetween. It is actuated by the same drive chain In in unison with the roller The rollers 4 and I5 each include series of knurled collars having cooperative relation with the larger roller |3 at peripherally spaced points. overhanging the roller l3 in peripherally spaced relation is a guide or deflector plate l6, supported at IT, through apertures in which the knurled collars of the rollers l4 and I5 project into frictional engagement with successive sheets or cards passing about the roller l3. The arrangement is such that the advancing sheets or cards passing beyond the guide table 2 are engaged between the rollers l3 and I4, and are deflected downwardly about the periphery of the roller l3 by the deflector plate |6. The dependent portions of the sheetsor cards are then engaged by the succeeding roller l5 which continues their advancement vertically as shown in Fig. 4.

Pivotally mounted at l8 back of the roller l3 and extending thence within the narrow spaces between succeeding axially aligned sections thereof, is a series of trip levers IS. The free ends of the trip levers l9 project slightly beyond andabove the periphery of the roller l3 into the path of the advancing sheets or cards The trip levers I 9 are interconnected by links with corresponding oscillatory pusher arms 2| pivoted at 22 eccentrically attached to each of which is a retractile spring 23 which tends to urge the pusher arm forwardly into engagement with the advanced card, and simultaneously elevates the trip arm l9. The advancing card passing about the periphery of the roller l3 beneath the deflector plate I 6 engages and depresses the ends of the trip levers l9, as shown in Fig. 4. The depression of the trip levers I9, by thrust motion of the links- IS, the latter is released and is retracted by the spring 23 acting through the push arm 2| and link 20. By the same action the push arm 2| exerts a thrust pressure upon the top marginal area of the released card or sheet, as shown in Fig. 3, to push the top margin of the card or sheet into engagement with the knurled periphery of the roller IS. The latter then, additional to its previous feeding function in the plane of the sheet, tilts the sheet or card bodily, broad side foremost, as shown in Fig. 3. At about the same moment, an oscillatory kicker sector 25 engages the bottom marginal area of the upright card or sheet and pushes it off the ledge onto a table 26, of which the ledge 24 comprises apart. Immediately beneath the feed roller I3 is a sprocket wheel 21 having driven engagement with the primary chain belt l0, and having attached thereto a sprocket wheel 21a for unison rotation, having driving engagement with a second endless chain belt 28. The chain belt 26 passes over an idler sprocket 29 and an intermediate guide and belt tightener 30. The reach of chain belt 28 between the sprockets 21a and 29 is substantially vertically aligned, and is medially engaged by a vertically adjustable sprocket wheel 3|. The latter is journaled upon a frame extension 32 of the vertically adjustable table 26 of which the ledge 24 is an integral part. The table 26 is mounted between the side frames 8 for vertical sliding adjustment, by means of a rack and gear adjuster 33 4 controlled by a hand wheel 33a. The outside of the side frame 8 is graduated at 34 with which a pointer 35, connected to the table 26, coacts to enable accurate adjustment of the table 26 to agree with the vertical dimensions of the sheets or cards.

As the table is elevated and lowered the sprocket wheel 3| travel to and fro relative to the drive chain belt 28, and is uniformly driven by the travel of the chain belt in any position of adjustment. The sprocket wheel 3| is connected by a pitman 36 with a crank 31 connected to the oscillatory fkicker sectors 25 and 26. The latter are movable to and fro in spaced slots in the ledge 24 of the table by rotation of the sprocket wheel 8| and oscillation of the crank 31, to push the lower portion of the sheet or card, broad side foremost, oil the ledge 24 and out of the path of the succeeding sheet or card. The table 26 is provided with an adjustable inclined follower 36 against which the succession of sheets or cards are assembled in a pack 39 as shown in Fig. 1.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in. order to comply with the statute the invention has been described in language more or less specific as to structural features. it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
