((13. 83-1} This invention relates to an apparatus for separating various portions of bound multileaf documents. More particularly the invention relates to a novel apparatus for feeding, slitting and separating sheets from bound multileaf documents such as magazines.

In the retailing of magazines a vendor usually has one or more unsold copies of any particular magazine issue left over and these are usually returned to a distributor. After accumulating a quantity of old issues the distributor in many cases strips the covers from such issues and returns the same to a wholesaler for credit. The task of stripping the covers from the magazines has heretofore constituted a tedious and time consuming task and for the most part has been carried out by hand which gives rise to relatively high labor costs.

The prime object of the instant invention is to provide a machine which is capable of efliciently stripping the first sheet from multileafed documents such as magazines and delivering these first sheets and the remaining portions of the documents to separate collecting stations respectively.

Another object of the invention is to provide a novel magazine cover removing apparatus wherein after being moved past a slitting blade a magazine is flexed so as to urge the cover in the region of the slit to move away from the remaining portion of the magazine thereby facilitating separation of the out parts of the magazine.

Another object of the invention is to provide a novel impact producing mechanism for rapidly oscillating a portion of a slit magazine so that the slit cover thereof is shaken loose from the remaining portion of the magazine.

Another object of the invention is to provide a magazine separating apparatus having novel means for insur ing the severance of at least the cover from the remaining portions of the magazine and for reliably guiding the separated portions of the magaine along two distinct feed paths respectively.

Other objects of the invention will become apparent as the disclosure progresses.

FIG. 10 is an elevational view of a portion of the magazine cover transport means as seen from a direction indicated by arrow F of FIG. 1.

A very general description of the instant apparatus will be made with reference to FIG. 1. The machine comprises a document retaining means 1t) which is adapted to receive and support a stack of magazines that are to have their covers removed. Belt and pulley means are provided for serially transporting magazines from the retaining means it along a predetermined feed path 11 through the machine. As each magazine moves along said feed path it successively passes a cutting station 12; a magazine flexing station 13 and a cover intercepting station 14. From station 1d the severed magazine cover is guided along a divergent feed path 15 to a suitable collecting or stacking station while the remaining portion of the magazine continues its movement along the feed path 11 to another suitable collecting or stacking station.

Referring now to the structural details of the machine as shown in FIGS. 1 and 2 the instant apparatus comprises a main supporting frame 21), FIG. 2 having a horizontal upper deck plate 21 secured thereto. The deck plate 21 is contoured so as to essentially define the floor area of the stack retaining stat-ion 10, the relatively narrow longitudinal feed path 11, and the feed path 15, all as is generally illustrated in FIG. 1. Fixedly mounted on one end of the deck plate is a first vertically disposed edge guide plate 22 that is disposed substantially normal to said feed path 11, and a second vertically disposed and slightly elevated (FIG. 2) face guide plate 23 that is disposed parallel to and along the initial portion of said feed path; said guide plates being mounted on the machine frame by any suitable fastening means. A fillet type arcuate guide plate 24, FIG. 2, is fixedly mounted on the deck plate 21, the guide surfaces at the opposite ends thereof being respectively coextensive with and parallel to the operative guide surfaces of said guide plates 22 and 23. Four vertically disposed shafts 25, 26, 27' and 3d are rotatably mounted on the machine frame and extend through the deck plate 21, these shafts having feed rolls 31 and 32 and

pulleys

33 and 34 secured to their respective upper ends. Looped around

pulleys

33 and 34 is a pair of

belts

35 and 36, FIG. 2, the inner lengths or runs of which are disposed generally between the lower edge of guide plate 23 and the deck plate 21 and extend slightly beyond the plane of the guide plate 23 as is best seen in FIG. 1. The periphery of roll 31 is disposed adjacent the feed path 11 and extends through a suitable aperture formed in the arcuate guide plate 24 while the opposed and cooperating roll 32 extends beneath the lower edge of plate 23 and into said feed path. The lower ends of

shafts

25, 26, 27 and 34) are rotatably supported and driven by any suitable drive means mounted in the machine frame beneath the deck plate 21 so as to rotatably drive the various associated rolls and pulleys in the directions noted by the arrows in FIG. 1.

The roll 31 and its supporting shaft may be adjustably mounted for movement toward and away from the roll 32, the adjusting means here being the same as that for certain other positionally adjustable rolls to be subsequently described. This adjusting feature is provided for the various rolls so that the machine may accommodate magazines having various thicknesses.

A vertical pillar post 4t) is fixed to the machine frame and supports a horizontally disposed L-shaped outboard support bracket 11 that is secured thereto by any suitable fastening means. A vertical shaft 42 extends through a suitable opening in the deck plate 21 and is rotatably supported at its upper outboard end by said L-shaped bracket 41 as is best seen in FIG. 3. Rotatably fixed to the intermediate exposed portion of shaft 42 is a feed roll 43 having a peripheral portion which is disposed along said feed path and which cooperates at its lower end with an opposed roll 44 disposed on the other side of the feed path as is best seen in FIG. 3. Roll 44 is rotatahly mounted on an upstanding shaft 45 that extends through a suitable opening in the deck plate 21; shaft 45 being rotatably mounted in the free end of an adjusting lever 16 that in turn is pivotally mounted on an upstanding pivot shaft 47. The free end of lever 46 is articulately connected to a threaded link that extends horizontally through a suitable aperture 51 formed in an upstanding lug 52 fixed to the machine frame 24 A spring 53 operatively disposed between link and lug 52 effectively serves to yieldably bias the roll 44 toward roll 43 to an extent determined by the setting of a nut 54 that is threadedly engaged with the outer end of link 5%) and abuts the outer face of said lug 52. The pivot shaft 47 is fixedly mounted on the horizontally extending legs of a U-shaped bracket 55, FIG. 1, that is fixed to the machine frame.

A cutting blade 56, FIGS. 3 and 7, extends into the feed path 11 at a point below the roll 43 and opposite a lower portion of roll 4-4; the cutting blade being fixedly supported by means of a two piece laminated clamping bracket unit 57 that is secured to said pillar post 46 by means of a suitable screw 69, FIGS, 3 and 7. The aperture 61 in unit 57 through which screw 61) extends is elongated as shown in FIG. 3 so as to permit the adjustable positionment of the cutting edge of blade 56 with respect to the document feed path 11 thereby affording a control over the depth of cut produced by blade 56.

The machine station 13 for flexing the magazine after its cover has been slit comprises a second vertical shaft 63 that extends through a suitable aperture in the deck plate 21 and is rotatably supported at its outboard end in said L-shaped bracket 41. To the intermediate portion of shaft 63 is fixed a roll dd whose peripheral portion is disposed along the feed path and is adapted to cooperate with an opposed roll 65 that is fixed to a vertical shaft 6-6. The shaft as, FIG. 4, extends through a suitable aperture in the deck plate and is rotatably mounted in the horizon tally disposed leg portions of a U-shaped yoke 67, the horizontal lower leg of which is disposed in a suitable opening formed in the frame and deck plate. The yoke 67 is pivotally supported on said shaft 47 so as to permit roll 65 to be adjustably positioned relative to its cooperating roll 64; this positional adjustment being controlled by an adjusting device '72, FIG. 1, that is similar to that shown at Sit-54 for the lever 46. Fixed to the lower part of shaft 66 is a second roll 73, FIG. 4, that is disposed in opposed cooperating relation with respect to a four lobe cam 74, FIGS. 4 and 6, fixed to said shaft 63. Rotation of cam 74 causes the cam lobes to strike and intermittently fiex the lower edge of the magazine as the latter progresses along feed path 11 as will be described. The magazine camming station 13 of the machine also includes a curved cam arm 75, FIGS. 1, 2 and 4, that is pivotally mounted on said shaft 47 and extends generally downstream along said feed path as best shown in PEG. 1. The cam arm 75 is pivotally adjustably positioned with respect to the feed path by means of an adjusting device 76, FIG. 1, that is also similar to that shown at 5tl-5 i for said lever 46.

After leaving camming station 13 the magazine enters the cover separating station 14 which includes a generally vertically tapered separator blade Stl that is fixedly attached to the machine frame by any suitable means. The upstream nose portion 81 of the horizontally curved blade is vertically shortened as is best seen in FIG. 2 and extends into the center of the feed path at a point just downstream from the end of the curved cam arm '75 so as to be in a position to intercept, as illustrated in FIG, 5, the severed cover of the slightly flexed magazine that is moving out of the camming station 13. Disposed in opposed cooperating relation to the upstream portion of the separator blade 80 is a pair of axially spaced

rolls

82 and 83, FIG. 2, that are fixed to a shaft 84 that extends through a suitable aperture in the deck plate and is rotatably mounted in the horizontally disposed legs of a U-shaped bracket 35. Bracket 35 is pivotally mounted on said shaft 47 and is pivotally adjusted by means of an adjusting device 36 that is also similar to that shown at 513-54 for said lever 46.

When the severed cover and the remaining portion of the magazine are separated by the intercepting blade 80 they proceed along their respective divergent feed paths 15 and 11, KG. 1, under the action of separate feed drive means; such feed drive means including a roll 89, FIG. 1, fixed to a shaft that extends through a suitable aperture in the deck plate and is rotatably mounted on the horizontally extending arms of a U-type bracket 91 that is pivotally mounted on an upstanding stud 92 fixed to the deck plate 21. The pivotal position of bracket 91 may be adjusted by means of an adjusting device 9'3 that is also similar to that shown at 50-54 for said lever Roll 89 is disposed in opposed cooperating relation with respect to a roll 94 that is rotatably fixed to a vertical shaft 95. Shaft 95 extends through a suitable aperture in the deck plate 21 and has its upper outboard end rotatably supported by a horizontal projection 96, FIGS. 1 and 10, formed on an upstanding bracket 97 that is secured to the deck plate. Fixed to bracket 97 is a vertically disposed shaft 100 that rotatably supports a first and a second pair of similar arms 101 and M2 that respectively rotatably mount at the free ends thereof rolls 103 and 104. The arms 161 and 102 are suitably biased as by means of springs so as to yieldably swing the rolls 103 and 104 into peripheral engagement with the said roll 94. As will be apparent shaft 95 and roll 94% when driven will frictionally rotate the rolls 103 and 1%. Rolls 1% and 1124- extend a short distance through suitable slots formed in the adjacent portion of the separator blade 81D and thus are capable of frictionally engaging and driving magazine covers that are moving along the said divergent path 15.

Several light cantilevered type leaf spring elements are provided for guiding the documents through the separating station 14; such elements including a horizontally bowed leaf spring guide 165, FIG. 1, that is secured at one end to an upstanding post 1% fixed to the deck plate; the other free end thereof serving to yieldably bias the magazine covers into engagement with the said driven feed rolls 1% and 194. Post 1G6 also supports a similar leaf spring guide 1tl7 that extends downstream of feed path 15 so as to guide covers C along said path 15. A third leaf spring guide 108, FIG. 1, is secured to the lever 91 and extends upstream of feed path 11 so as to guide a magazine portion M between the rolls 89, 94. Any suitable hoppers, stackers or other receptacles may be provided for separately receiving the covers C and the remaining portions M of the magazines that move along the respective feed paths. A rnu-ltilator cutting blade 110, FIGS. 9 and 10, is fixedly supported on the machine frame below roll 94 by means 57a, FIG. 10, that are similar to that for blade 56, said blade operatively extending into the path 11 of movement of the magazine portion M so as to further slice or otherwise destroy the remaining portion of each magazine body.

It will be understood that the periphery of the various feed rolls are coated with a friction material such as rubber, and that the lower ends of the

shafts

42, 45, 63, 66, 84, 90 and 95 are rotatably supported and driven by any suitable means mounted on the machine frame 20 beneath the deck plate 21. These shafts may be driven from a main input shaft 111, FIG. 1, having a pulley 112 secured to the outer end thereof.

In the operation of the instant machine a stack 113 of magazines is placed on edge on the deck plate 21 so as to be received by the document retaining means defined essentially by guide plates 2244. As the leading magazine is engaged by the adjacent run of the driven

belts

35 and 36 it will be driven longitudinally along the feed path 11 and between the rolls 31 and 32 to the cutting station 12. The reversely rotating roll 31 permits only a single magazine to be fed at a time into said cutting station. As the magazine passes between the feed rolls 43 and 44- of station 12 the cutting blade 56 slits the front cover C along a line parallel and adjacent to the lower bound 5 edge 115, FIG. 3 of the magazine. The rolls 43 and 44 progressively feed the slit magazine along the feed path 11 and into the nip of rolls 64 and 65, FIG. 4, of the magazine flexing station 13. Here the camming blade 75 progressively flexes or bends the lower portion of the magazine and cover to the left as seen in FIG. 4 while the rotating four lobe cam 74 simultaneously intermittently strikes and displaces the lowermost bound portion 115 of the magazine thereby insuring that the actual severance of the slit cover from the rest of the magazine is complete. This camming and flexing of the lower portion of the magazine produces a bowing of the magazine such that the convex outer side of the latter faces the upper side of the feed path 11 as seen in FIG. 1. This bowing tends to separate the lower part of the cover C from the rest of the magazine M as illustrated best in FIG. 5 and the continued movement of the magazine into the cover separating station 14 will thus permit the leading edge 81 of the separator blade 80 to initially intercept the lower portion of the slit cover and thereafter cam the entire cover into the diverging feed path 15 as is sequentially illustrated by the diagrammatic sketches of FIGS. 8 and 9. The severed cover C is fed along path 15 by the drive action of the feed r-olls 103 and 104 while the remaining portion M of the magazine continues its movement along the path 11 under the driving action of the roll 94. Each successive magazine as it passes through the machine thus has its cover cut off and transported to a separate receptacle while remaining portion of each magazine is further out up by blade 110 while being transported to another receptacle. The collected remaining portions of the magazines are usually removed and disposed of while the magazine covers are returned to wholesalers as evidence of the amount of credit due.

As will be seen the instant machine can accommodate a wide variety of magazine sizes and once adjusted for a particular magazine thickness needs only to be supplied with stacks of that magazine whereafter the transport, cutting, flexing, and separating functions are automatically and rapidly carried out. One prototype of the instant machine has been constructed so as to efficiently process magazines at a rate in excess of 50 per minute.

The instant apparatus may be provided with any suitable base and power drive means such as that illustrated by U.S. Patents 753,207 and 1,377,853, or by the well known Model AV machine produced by Pitney-Bowes, Inc.
