AUXILIARY TAG FEEDING MAGAZINE FOR PRINTING PRESSES v C. E. ZOOK 5 Sheets-Sheet 3 Filed OCT.. 22, 1956 kR.. Zw .N El I U c n .mi

My invention relates lto auxiliary tag feeding magazines for feeding shippingt'ags ofcorniilece in a pack seriatim to the suction feed `arm 'of printing presses 'of 'the Kluge type, especially, although not 'e'c'essarily,` 'such presses being 'exemplified as a type in U. S. Patent Nos. "1,694,015 v and 2,088,377 to A. VKluge et al. and dated December 4, 1928 and July 27, 1937, respectively.

By way, of premise, it isV the practice in such presses to feed a pack of sheets on edge, one behind aither, upwardly and forwardly on a stock feed magaine table in a straight line to position the 'sheets in a feed plane at the front of the pack parallel with across suction arm States Patent on a suction feed arm for feeding frorna feed plane to the press by said feed arm.

However, shipping tags, because'they are equipped with a grommet in one end thereof and must be fed to the press with their -grommetequipped ends at the same side of the pack, will not lie at against each other in a pack, because their gromme't-equipped ends space the tags apart further at said ends than at theirother ends. Therefore, such ytags cannot be yfed like sheets by the usual means for positioning the tags successively in a feed plane parallel with the cross suction arm of the suction feed arm. g p k Having the foregoing in mind, it -is the primary object of my invention to provide a tagV feeding Imagazine equipped with means for feeding a pack of such shipping tags, one behind the other, into the proper feed plane relative to the cross suction yarm, notwithstanding spacing ofthe tags in the pack further apart at Ytheir grommetequipped ends than at their other ends.

Another object is to accomplish the foregoing by feeding a pack of shipping tagsr in fanwise arrangement-to compensate for further spacingapart of their grommetequipped ends than their other ends and in yan arcuate path to position tags at the front of the pack in the proper feed plane.

Still another object is to provide in conjunction with the foregoing an arcuately swingable follower arm for feeding the pack of tags in an arcuate path into the proper feed plane to compensate for their fanwise arrangement and further spacing apart of t-he grommetequipped ends than the other ends in the pack.

Yet another object is to povide for 'driving the f'ollower arm by means of the conventional stock feed magazine drive shaft and the intermittent, step-by-step ratchet and pawl drive shaft operating means of such presses and which operates under control of the sensing means of the presses.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully heeinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and 4in which:

Referring to the drawings by numerals, and rst briey to the parts of the Kluge type of press with which my invention is" especially concerned, this type of lpress includes a sheet feed table 1 forming part of a sheet feed magazine of the press and which inclines forwardly and upwardly relative to the press platen, not shown, and has right and left sides 3, 5, right and left upstanding frames 7, 9 at said sides, and a front edge 11. A subjacent bracket 13 under the right side of the table 1 supports said table.

A horizontal drive shaft 15 forming part of the sheet feeding magazine of the press extends along the front edge 11 of said table above said edge and is journaled through the side frames 7, 9. The drive shaft 15 is driven intermittently, stepby-^step, clockwise as viewed in Figures l and 2 by an intermittent ratchet and pawl drive comprising the following.

A rocker plate 17 rotatable on the drive shaft 15 at the left side 5 of the table 1is rocked clockwise and' counterclockwise by a vertically reciprocating rod 19 operatively connected to said plate as at 21. A pivoted, gravity drive pawl 23 on the rocker plate 17 normally engages a ratchet wheel 25 fast on said shaft 15 and moves the shaft 15 clockwise when the rocker plate 17 is rocked clockwise. A spring press pivoted holding pawl 27 on a relatively fixed bracket 29 normally engages and prevents reverse rotation of said wheel 25 and shaft 15.

A circular, circumferentially flanged pawl releasing plate 31, having slots 33, 35 in its flange 37 through which the

pawls

23, 27 work, is rotatable on the shaft 15 so that said flange disengages said

pawls

23, 27 to permit of reverse rotation of the shaft 15 by a hand crank 33 thereon and for a purpose presently apparent. A weighted hand lever 39 on the pivot 41 of the pawl 27 holds said pawl 27 engaged. A slot and pin connection 43, 45 between said lever39 and plate 31 provides for rotating said plate 31 into'pawl releasing position by operation of the lever 39.

The Kluge type press further includes a suction feed aim 47 and a sensing control for the shaft 15. The suction feed arm 47 has a cross arm 49 with suction tips thereon, as at 51, and is oscillat'ably mounted to pick off` the front sheets, or the like, of a .pack fed on edge up to 'the front edge 11 of the table 1 into a feed plane parallel with said cross arm 49, all as described in detail in Patent No. 2,088,377 to A. Kluge et al. and to which reference may be had for a full disclosure of the suction feed and The sensing control comprises a rock shaft 53 journaled ,inA the frames 7, 9 abve the drive shaft 15 and having a sensing arm 55 depending therefrom, a spring tension crank arm 57 on said shaft tensioned by a spring 54 whereby said rock shaft is normally urged clockwise as viewed in Figure 2 to swing the sensing arm rearwardly clockwise over the table 1, a weighted pivoted drive pawl disengaging arm 59 on the plate 17 normally disengaging said drive pawl 23, as shown in Figure 4, and operating pin and slot lost

motion connections

61, 63 between said plate 17 and the crank arm 57, all forming the subject matter of Patent No. 1,694,015 to A. Kluge et al., previously noted, and to which no claim per se is made herein. Suffice it to explain that the sensing arm 57 moves rearwardly, as shown in Figure in the Kluge press, each time the stack is depleted at its front end, and when said stack has been depleted by a certain number, the sensing arm then swings the drive pawl disengaging arm 59 so that the drive pawl 23 can engage the ratchet wheel to cause operation of the drive shaft 15 for feeding a front'sheet in the stack into the feeding plane, and as the pack is thus fed, the sensing arm is swung forwardly to cause the drive pawl to be disengaged to stop the feed when the depleted pack has been fed to position a front sheet into the feeding plane. Also, the sensing arm 55 is swung forwardly and spaced from the pack, as shown in Figure 4, out of interference with operation of the suction arm 47 when said arm operates for feeding, all as described in the aforesaid Patent No. 1,694,015.

My auxiliary tag feeding magazine comprises a fiat deck panel fitting flatly on the table 1 between the frames 7, 9 to incline upwardly and forwardly like the table 1. The deck panel 75 is provided with right and left, front, upper corners 77, 79 projecting forwardly of the front edge 11 of the table 1 and with a rectangular front notch 81 between said corners into which shipping tags may drop off the panel 75 onto the table to be fed therefrom by the suction feed arm 47. Otherwise than as described, the deck panel 75 may be of any desired shape. The deck panel 75 is detachably secured to the table 1 by a threaded hook 85 extending through said corner 79 and which hooks over the front edge of the table 1 and is provided with a tightening nut 87 threaded thereon, said deck panel being further secured to the table 1 by a single screw 89 extending through the panel 75 and through the table 1.

Surmounting the deck panel 75 is a flat band arcuate guide bar 91 which curves upwardly from one side, a right side 94, of said panel 75 into overlying relation to the notch 81 for guiding a pack of shipping tags in an arcuate path laterally and upwardly to position the front tag in the feeding plane when said pack is fed by means presently described, and the pack of tags 93 is positioned edgewise on said panel 75 in fanwise position with the grommet-equipped ends 95 thereof resting against the guide bar 91, as shown in Figure l.

The pack feeding means comprises a follower arm 97 pivotally mounted for swinging laterally and upwardly of the panel 75 from a starting position about an axis normal to said panel 75 to feed the pack of tags 93. The follower arm 97 comprises a driving arm section 99 fixed on the bottom of a bevel gear 101 rotatable on a stud 103 fixedly extending upwardly through the panel 75 and at a normal angle thereto. A washer 105 on said stud 103 spaces said arm section 99 from the panel 75.

The arm section 99 carries an adjustable arm section 107 provided with a rectangular follower plate 109 fixed thereto, as by lug bolts 111, and having suitably fixed thereto as at 112 a rectangular pusher plate 113 adapted to push against the pack of tags 93. The follower plate 109 is provided with a front booster leaf spring 114 acting through a notch 115 in the pusher plate 113 against a rear tag 93 of the pack to prevent said rear vtag from adhering to the pusher plate 113. The adjustable arm section 107 is pivoted by a screw 118 to the arm section 99 for swinging adjustment to adjust the pusher plate into 4 radial position to the guide bar 91 for the following reasons.

The guide bar 91 is adjustably mounted for flexing to vary its arc of curvature for guiding packs of tags 93 of different sizes in arcuate paths and maintain it in its different adjustments substantially concentric to the axis of swinging movement of the follower arm 97, and for proper feeding of the pack of tags 93, the pusher plate 113 should be adjustedV substantially radially of the guide bar 91 in the different arcuate adjustments of said bar for swinging by the follower arm 97 in an arcuate path substantially concentric to the guide bar 91.

For adjustably mounting the guide bar 91, it is bolted adjacent its ends, as at 116, 118 to a pair of longitudinally slotted, lateral bars 117, 119 at the front and rear of the panel 75. The rear bar 117 is slidably and pivotably adjustable on a threaded stud 121 extending upwardly from the panel 75 through the slot 123 in said rear bar, the stud 121 being provided with clamping nuts 125 thereon for securing said bar 117 in adjusted position. The front bar 119 is lonigtudinally, slidably adjustable on a pair of threaded

studs

127, 129 extending upwardly from the panel 75 through the slot 131 in said bar 119, said

studs

127, 129 being provided with clamping nuts 133, for retaining said bar 119 in adjusted position.

The drive shaft 15 is drivingly connected to bevel gear 101 for swinging the follower arm 97 by the following means. A driven shaft 137 at the upper right hand corner 77 of the panel 75 is journaled parallel with said drive shaft 15 in a bearing 139 on the panel 75. A bevel gear pinion 141 fast on one end of the driven shaft 137 meshes with the bevel gear 101. A sprocket and chain drive 143 connects one end of the drive shaft 15 with the other end of the driven shaft 137 for a one to one ratio of drive from the shaft 15 to the shaft 137.

A spring wire tag hold-down and stop member 145 extends forwardly over the panel 75 diagonally over thc pack of tags to prevent upward displacement of said tags at one end of the tags. The member 145 includes a rear lonigtudinally slotted bar 147 pivotably and slidably mounted on a stud 149 rising from the rear portion of the panel 75 and extending through the slot 151 in the bar 147, the stud 149 being provided with clamping nuts 153 thereon for holding the bar 147 and hence the member 145 in adjusted position. As will be seen, the holddown member 145 is adjustable laterally and longitudinally as may be required for tags of different sizes and said member is provided with a hooked front stop end 155 for positioning in front of a front tag of the pack at the feed plane, said stop end 155 being positioned at the upper edge and at one side of the pack.

A curved resilient wire tag hold-down and stop member 157 extends forwardly over the pack of tags 93 at the other side of the pack for holding down tags in the feed plane at the front of the pack, and, together with the member 145, holds down the front tags of the pack 93 at top front corners of said front tags. The member 157 has a down-turned front stop end 159 for the front tag in the pack and is clamped on the stud 129 by collar 161 and a wing nut 163 on said stud 129.

Two resilient

wire stop members

165, 167 are provided at opposite sides of the pack of tags 93 for engaging the ends of the front tag of the pack below the

ends

155, 159 of the

members

145, 157 for coaction with said ends 155, 159 to yieldingly hold the front tag of the pack 93 in the feed plane.

The stop members curve forwardly laterally over the front tag 93 from stud 127 on which it is swingably adjustably mounted by a clamping collar 169 anda wing nut 171 for variably positioning in front of the front tag.

The stop member 167 curves forwardly and is provided with a hooked front stop end 173 and is mounted opposite the front end 175 of the guide bar 91 to form a second guide coacting with the front end 175 of the guide bar 91 to confine the tags 93 at the front end of the pack against displacement endwise. The member 167 is attached by a screw 177 to a horizontal slotted arm 179 swingably and longitudinally adjustably mounted on an angularly related arm 181 by a screw 183 extending through the slot 185 in the arm 179. The arm 181 has a longitudinal slot 187 straddling the stud 103 and is clamped on said stud by clamp nuts 189.

The operation of my auxiliary tag feeding magazine will be readily understood from the foregoing and the following further explanation thereof. To load the auxiliary magazine, the follower arm 97 is swung clockwise as viewed in Figure 1 to extend rearwardly of the deck panel 75, as regards its front edge, and to set and position the pusher plate 113 adjacent the right side 94 of said panel 75. This is accomplished by operating the drive shaft 15 by the hand crank 38 reversely, that is, counter-clockwise as viewed in Figures 1 and 3, whereby, through the described driving connections from the shaft 15 to the bevel gear 101, said gear 101 is driven clockwise as viewed in Figures 1 and 6 to correspondingly operate the follower arm 97 clockwise. The pack of tags 93 is then loaded on edge on the panel 75 in front of the pusher plate 113 and in the fanwise position, with grommet-equipped ends engaging the guide bar 91, all as previously described and as shown in Figure 1. Now, in response to intermittent drive of the drive shaft 15, clockwise as viewed in Figures 1 and 3, by the previously described ratchet and pawl drive means, the bevel gear 101 will be intermittently driven counterclockwise as viewed in Figures 1 and 3 to correspondingly drive the follower arm 97 so that the pusher plate 113 will intermittently push the pack of tags 93 in the previously described arcuate path up the deck panel 75 until the tags 93 are positioned seriatim against the stop ends 155, 159, 173 of the

members

145, 157, 167 and against the stop member 165 to be yieldingly held thereby in the feed plane for feed by the suction feed arm 47 to the press, not shown. When the foremost tag is in the feed plane, the operation of the drive shaft 15 is stopped to stop feed of the pack of tags 93, and as the pack is depleted at its front of a certain number of tags, the drive shaft 15 resumes its operation under control of the sensing means, all in a manner which will be clear from the foregoing description of parts and the before mentioned U. S. Patent No. 1,694,015.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be,resorted to, falling within the scope of the invention as claimed.
