  • This slide member 110 has a booklet supporting finger 112 pivoted thereon so as to be foldable flush with the top surface of the slide member 110 in the direction of advance of the accumulating booklets B (compare Figs. 7 and 9).
  • the supporting finger 112 is maintained in an erect position by a torsion spring 113 arranged at its pivot mounting on the slide member 110 and is thereby disposed for supporting the incoming booklets B uprightly as illustrated in Fig. 7.
  • the slide member 110 is further biased by a compression spring 114 that is disposed over a guide rod 115 extending from the slide member 110 into the mounting block 11 so as to urge movement of the slide member 110 on the mounting block 111 reversely to the direction of advance of the accumulating booklets B and thereby maintain the finger 112 positioned for supporting contact With the incoming booklets B.
  • This compression spring 114 also serves as a return means for the slide member 110 after each group G of the booklets B is accumulated, as will appear more fully presently.
  • the slide member 110 With the slide member 110 at its starting position, as determined by a suitable stop member such as is indicated by dotted lines at 116 in Fig. 7, and the supporting finger 112 erectly disposed, the first several incoming booklets B of a group G to be accumulated are held uprightly by the finger 112 as it shifts from a somewhat forwardly inclined to a vertical position against the pressure of its associated torsion spring 113, a back plate 117 being arranged on the mounting block 111 below the delivery pulley 26 as an opposed positioning stop. Also, when the supporting finger 112 reaches a vertical position, the slide member 110 as a whole will back off against the initial compression of the spring 114 as the incoming booklets B of the group being accumulated build up.
  • timing chain 118 may be driven in any suitable manner (not shown) from any convenient operating element of the booklet machine so as to provide it with a linear, rate of travel timed in accordance with the delivery rate of the booklets B and thereby cause it to move linearly at the same rate that the booklets B being accumulated advance in the booklet conveyor 101.
  • the top reach of the timing chain 118 may be arranged over the sprockets 119 in a length such that this positive advance continues until-the booklets B have been delivered in the number desired for the group G (which will be the number desired for ultimate packing as a group), at which time the slide member lug 122 will be released by the working lug 121 on chain 118 as it turns downwardly over the adjacent sprocket 119 to begin its return flight.
  • the released slide member 110 will be returned at once to its starting position by the compression spring 114, the supporting finger 112 folding fiush to pass beneath the accumulated group of booklets G and recover to an erect position for supporting the incoming booklets B of the next succeeding group to be accumulated, it being understood that the group of booklets just accumulated will be advanced as a group to the position indicated at G in Fig. 7 (by means to be described further below) as this recovery action of the slide member 110 and supporting finger 112 occurs.
  • the booklet conveyor 101 may be further fitted with yieldably biased gate members at its receiving end adjacent the delivery pulley 26 as illustrated in Figs. 10 and 11.

  • the advance of the booklets B as they accumulate in the conveyor 101 results in folding the gate elements 123 and 124 outwardly against the tension of their associated springs 126 and 127, and the gate elements 123 and 124 arranged to fold flush ultimately with the side guide elements 108 so that the advancing booklets B are then unobstructed as they accumulated under the control of the slide member 110 and supporting finger 112.
  • the upper and lower gate elements 123 and 124 are preferably provided to form these gate members so that the upper gate element 123 may remain unafifected while the lower gate element 124 is folded outwardly to allow passage when necessary for the advancing means provided for the fully accumulated booklet groups G, as described just below.
  • the fully accumulated booklet groups G are advanced in the booklet conveyor 101 by means of sprocket chains 128 carried on sprocket wheels 129 and 130 adjacent the receiving and delivery ends, respectively, of the conveyor 101, and arranged with its top reach riding on support rails 131 arranged at each side of the bottom guide element 109 (see Fig. 10).

The general'arrangement of the packing devicevv 100. of the-presentinvention for accomplishing this packmgoperqation isshowninFig. 4.of-,the drawing ascomprisiuga booklet-conveyor 101 arranged to receive the booklets continuously;v as at ;;B and advance themlntermittently n groups.- as at G.--to: an ejector, mechamsm 102 operating transverselwofthe booklet conveyor 101'to transfernthe groups of booklets G successively to booklet handling compartments 103, a plurality of which compartments 103 are supported in regularly spaced relation for circular movement about a common vertical axis as at 104 so that these compartments 103 travel successively between a loading station adjacent the booklet conveyor 101 and opposite the ejector mechanism 102 for receiving the transferred groups of booklets G, and a succeeding station adjacent a packing container conveyor 105 adapted for presenting empty packing containers C opposite the compartments 103 to receive a group of booklets G displaced therefrom in a manner to be described more in detail presently. The packing container conveyor 105 is arranged with carrying frames 106 in which the packing containers C are placed by hand ahead of the point at'which the groups of cigarette booklets G are received from the handling compartments 103, but otherwise the packing operation is carried out entirely automatically, the loaded packing cartons C being advanced past a further ejector mechanism 107 by which they are removed from the carry frames 106 to be collected suitably for storage or shipment.
The manner in which the booklet conveyor 101 is arranged for continuously receiving the booklets B and advancing them intermittently in groups G is shown best in Figs. 7 to 11 of the drawings. In Fig. 7, the receiving end portion of the booklet conveyor 101 in lon itudinal section with the booklets B being delivered uprightly by the terminal pulley 26 of the previously mentioned booklet machine delivery mechanism 24, which operates to direct the booklets B continuously from the booklet machine to the conveyor 101.
In order to receive the booklets B and allow them to be advanced uprightly as shown, the booklet conveyor 101 is constructed with a trough-like directing channel fitted with side guide elements 108 and a bottom guide element 109 (see Fig. Provision for accumulating the continuously delivered booklets B in the upright position shown is made by means of a slide member 110 carried in a mounting block 111 for reciprocation in aligned relation with the bottom guide element 109. This slide member 110 has a booklet supporting finger 112 pivoted thereon so as to be foldable flush with the top surface of the slide member 110 in the direction of advance of the accumulating booklets B (compare Figs. 7 and 9). Normally, however, the supporting finger 112 is maintained in an erect position by a torsion spring 113 arranged at its pivot mounting on the slide member 110 and is thereby disposed for supporting the incoming booklets B uprightly as illustrated in Fig. 7.
The slide member 110 is further biased by a compression spring 114 that is disposed over a guide rod 115 extending from the slide member 110 into the mounting block 11 so as to urge movement of the slide member 110 on the mounting block 111 reversely to the direction of advance of the accumulating booklets B and thereby maintain the finger 112 positioned for supporting contact With the incoming booklets B. This compression spring 114 also serves as a return means for the slide member 110 after each group G of the booklets B is accumulated, as will appear more fully presently.
With the slide member 110 at its starting position, as determined by a suitable stop member such as is indicated by dotted lines at 116 in Fig. 7, and the supporting finger 112 erectly disposed, the first several incoming booklets B of a group G to be accumulated are held uprightly by the finger 112 as it shifts from a somewhat forwardly inclined to a vertical position against the pressure of its associated torsion spring 113, a back plate 117 being arranged on the mounting block 111 below the delivery pulley 26 as an opposed positioning stop. Also, when the supporting finger 112 reaches a vertical position, the slide member 110 as a whole will back off against the initial compression of the spring 114 as the incoming booklets B of the group being accumulated build up.
After the first several booklets B of the group have been delivered, however, it is necessary to provide a positive means for shifting the slide member 110 against the increasing pressure of the compression spring 114, and this is done through a timing chain 118 arranged below the slide member 110 on sprockets 119 with an idler tensioning sprocket 120 for maintaining the upper reach of the chain 118 properly taut. This timing chain 118 may be driven in any suitable manner (not shown) from any convenient operating element of the booklet machine so as to provide it with a linear, rate of travel timed in accordance with the delivery rate of the booklets B and thereby cause it to move linearly at the same rate that the booklets B being accumulated advance in the booklet conveyor 101. Accordingly, by providing properly spaced lugs 121 on the timing chain 118 for engaging a complementary lug 122 arranged on the bottom of the slide member 110, it may be adapted readily for actuating a positive advance of the slide member after the first severed booklets B of a group G to be accumulated have been delivered as noted above.
Also, the top reach of the timing chain 118 may be arranged over the sprockets 119 in a length such that this positive advance continues until-the booklets B have been delivered in the number desired for the group G (which will be the number desired for ultimate packing as a group), at which time the slide member lug 122 will be released by the working lug 121 on chain 118 as it turns downwardly over the adjacent sprocket 119 to begin its return flight. As this happens, the released slide member 110 will be returned at once to its starting position by the compression spring 114, the supporting finger 112 folding fiush to pass beneath the accumulated group of booklets G and recover to an erect position for supporting the incoming booklets B of the next succeeding group to be accumulated, it being understood that the group of booklets just accumulated will be advanced as a group to the position indicated at G in Fig. 7 (by means to be described further below) as this recovery action of the slide member 110 and supporting finger 112 occurs.
To provide supplementary support for the first several incoming booklets B of each group, and thereby further insure orderly handling of these first several booklets B as the slide member 110 and supporting finger 112 are recovering to starting position, the booklet conveyor 101 may be further fitted with yieldably biased gate members at its receiving end adjacent the delivery pulley 26 as illustrated in Figs. 10 and 11. As shown, these gate members suitably comprise upper and lower gate elements 123 and 124 hinged as at 125 in relation to the side guide elements 108 and biased by tension springs 126 and 127 so that they normally extend laterally inward of the conveyor 101 to provide the above noted supplementary support for the first several booklets B. The advance of the booklets B as they accumulate in the conveyor 101 results in folding the gate elements 123 and 124 outwardly against the tension of their associated springs 126 and 127, and the gate elements 123 and 124 arranged to fold flush ultimately with the side guide elements 108 so that the advancing booklets B are then unobstructed as they accumulated under the control of the slide member 110 and supporting finger 112. The upper and lower gate elements 123 and 124 are preferably provided to form these gate members so that the upper gate element 123 may remain unafifected while the lower gate element 124 is folded outwardly to allow passage when necessary for the advancing means provided for the fully accumulated booklet groups G, as described just below.
The fully accumulated booklet groups G are advanced in the booklet conveyor 101 by means of sprocket chains 128 carried on sprocket wheels 129 and 130 adjacent the receiving and delivery ends, respectively, of the conveyor 101, and arranged with its top reach riding on support rails 131 arranged at each side of the bottom guide element 109 (see Fig. 10). The sprocket chains 128 fitted at spaced intervals with booklet advancing lugs 132, the spacing of these lugs 132 being such as to accommodate a fully accumulated group G of the booklets B, and the chains 128 being mounted so that the lugs 132 are disposed at rest to allow successive groups G of the booklets B to accumulate between them under the control of the previously described slide member 110 and supporting finger 112, and are advanced intermittently to take over control of each booklet group G as it is fully accumulated and move it a step forward in the conveyor 101 so that accumulation of the next booklet group G may continue immediately in the next succeeding spacing between the-lugs 132. A succession of the booklet groups G is accordingly advanced by the lugs 132 in a step-by-step fashion to the delivery end of the conveyor 101, this intermittent advance being actuated and timed in relation to the other operating elements of genome the packing device 100 by= a commonactuat-ing means Whichis described "further below.
. At the deliveryend ofthe-conveyor- 101, :annpstan'dlrig stop element 133 -is fixedon the bottom guide element 109-topositionthe booklet-groups G'properly as they are advanced opposite the previously mentioned e ector mechanism 102, and to compress the fully advanced group-of booklets-=G against the lugs 132that trail it-andthereby confine -this booklet group G within the reach of the ejector mechanism 102; As. already explained, thisejector mechanism operates transversely of the booklet conveyor 101 for transferring the booklet groups G successively "to the booklet handling compartments 103, and it comprises for this purpose" an air cylinder-134 disposedwith an;associated piston rod 135 carrying' a pusher plate 136 to-move transv'erselybetween the stop element 133 and-the adjacent trailinglugs 132 and sweep the booklet group G confined-therebet-ween into the oppositely disposed booklethandl-ing compartment103. This action takes place while the intermittentlyadvancing chains -128:0f.--thebooklet conveyor 101 andagai-n is timed" from-- the-previously'mentionedfcommon actuating 'means which is still to be described below.
Thev booklet handling compartments 103 which receive thebooklet groups "G transferred from-the booklet con- .veyor 101 inthe manner noted-above arearranged-ina circular series for movement (about thexpreviously-"mentioned common axis 104, and four of-these compartments '103 are provided in the illustrated embodiment (see Figs. 4 and 6), although a greater or lesser plurality might be employed if desired. The circular movement of the ,compartments'103 about the common axis 104 is also actuated intermittentlygso thatthey-come to rest successively at a loading station opposite the booklet conveyor ejector mechanism 102 to receive the transferred booklet groups G. This intermittent motion is obtained through a Geneva motion formed by a four-station Geneva stop 137 mounted on the common compartment axis shaft 104 and a Geneva driver plate 138 mountedvon an adjacentcountershaft 139' (compare Figs. and 6). Thislcountershaft 139 is,driven directly from the bookletimachine through a worm wheelj1'40 that engages a worm 141 carried on a main'drive shaft 142 for the packing device 100 which, extends from a bevel gear pair 143 at.,which;it is driven from a latershaft 144 that is connected through. a sprocket ,chainqor, the like asindicatediniFigs. 4 and 7. at ,145 tothe shaftcarrying the delivery pulley 26. Thezcountershaft 139,is accordingly driven intimed relation withthetoperation fthe booklet machine, vand by suitable speed redjuctionat the worm 141 and worn-1' -,wheel, 140 may be made .to actuate theintermittent motion of the-booklet handlingfcompartments l03twithithe timingrequired by the number; of booklets B contained in each grouptG.
It is the Geneva motionljust described-that alsoserves as the previously meutionedicomrnon actuating means for the intermittent motion of all of, the other operating elements ofthe packing vdevice.100. Thus the booklet conveyor advancing chains 128 are. drivenintermittently througha bevel gear 146 carried atthe ,lowerend of theGeneva stop shaft, 104 (i. e. the common compartment axis shaft) to engage one bevel. gearof an oppositely disposedpair arranged-on an intermediate stub shaft as at 147 (see Fig. 5) to drivea further bevelgear, 148 on av lateral shaft149. that runstto a sprocket, andchain connecti0nat150 with the shaft carryingithe sprockets 130 over whichrtheiadvancingl chains 128 are mounted atfthe. delivery end of the. conveyor-101'. A sprocket and chain connection ,151is also arrangedjfrornttheshaft .104 for actuating the;intermitte.nt mo tion of packingcontainer conveyor 10.5, and al tripjfifngcr 152 isarranged on the countershaft 139 below the,wormlwheel140ilfor timed actuation-of a micro switch 153 through which .the' ejector mechanismsg102 and-107 are operatedon the booklet and packing container conveyors .llfll andlfls, as islexplained more fullyjbelow.
The booklet handling compartments 103 are illustrated in' detail in Figs.j12, 13 and'14,;and as shown they comprise body blocks' 154 that are adapted throughassembly plates 155 and a bracing ring 156 for mounting in spaced relation around a circular mounting plate 157 which is fixed directly on thecommon 'ax'is shaft 104*for intermittent movement as controlled by 'theabove noted Geneva motion. Each body block1'54 is-fitted with out- --'wardly=extendingside 'frarningarms 1'58*onwhichmounting blocks :1599are carried toreceivel-slidable studs 160 that are biased downwardly-by springs 161and' extend upwardly te/carry .a cross 'member 162 on which :a ;top guide'163 for the booklet group G is fixed so as toform in effect the top wall of the compartments. 103, although it is -made. adjustable bythe springs 161to ease the entrance of a' bookletqgroup G;
.The bottom wallfor the compartments 103 is formed by a plate member .164 which is fixed in place on a bracket element 165 that-is in turn secured to the bottom face of the body block 154. This-bracket'element 165 also serves to carry'slidable end wall members 166 which arefitted wit-h grooved slide arms 167 having an upper portionshaped in a narrower width to fit closed-end slots- 168 in the bottom face of bracket element 165, and a wider lower portion fitting open-ended slots as at.16 9 intbottom cover plates 170-fixed to the bracket element 165; The upper narrower portions of the slide arms1i67 terminate short; of the full length of the bracket element slots-168 so as to allow sliding movement for theend wall=members166 and compression springs 171 are disposed to bear against the ends of these upper portions from a seat as at 172 in the closed ends of the bracket slots168 so as normally to bias the endwall members 166 openly against adjustable stops 173 carried bythe-side framing arms 1 58.
'Theipurpose of incorporating these sliclable end wall members 166 in thebooklet compartments 103 is to allow compression of the booklet groups G as they are moved to the succeeding station at which they are displaced for;packi ng in the containerstC. This compression serves two purposes. In the first place, itacts to grip the booklet group G more tightly in the compartments 103 against the centrifugal force tendingto throw thebooklets B outwardly during the circular movement of the compartments 103; and, even more importantly, the compression results in arranging the booklet groups G with adequate compactness for packing nicely in the containers C.
To actuate the slidable end wall members 166 for obtaining this compression, a slotted cam plate 174 is mounted on a central pivot stud 175 extending downwardly at the middle of the bracket element 165, and the curved slots of this camplate 174 engage following pins 176 extending downwardly from the end wall slide arms 167 through clearance slots 177 in the bottom cover plates 170, so that rotation of the cam plate 174 on its pivot, stud 175 in the-direction indicated by arrows in Figs. -4, 6' and 12 results in drawing the end wall members 16.6 and thereby compressing endwise a booklet group G contained inthe compartment 103. Rotation .of the ,cam plate 174for this purpose is effected through a roller;178,carried by-a radially disposed extending arm 179 to .ride ,aacam rail 180 shaped to obtain the rateand degree of compression desired, ahump 181 (see Fig. 6), for example, being preferably formed in the cam rail 180 to,give-a final relatively heavy degree of compression as the; compartments 103 reach the station at which the booklet, groups G. are displaced into the packing containersC.
Displacement of thebooklet groups G from the compartments-103iis eifecte'd through amovable back wall plate 182arrangedto sweep outwardly between the end wall members 166. This movement of the back wall plate182 is provided for through slide rods 183 extending backwardly in the body block 154 to a recess 184 therein of sufiicient size to.accommodatea'crosshead 185 fixed onthe rear ends of the slide rods 1 83. This crosshead 185-,isfitted with a forwardly extending guide stud 186 7, on whicha spring 187 is carried to bear againstthe front 0 the .back wall;plate-1 82 normally in its retracted position. The above mentioned crosshead 185, however, is also side ,ofthe body block recess 184a and thereby maintain fitted with a downwardly extending mounting stud 188 that carries-a cam follower 189 in relation to a quick return cam elementjl90 mounted on a jack shaft 191 that isdriven through a chain and sprocket connection 192 from,thQGeneva drive shaft 139; Through this driving connection192, thecamelement is made to rotate once during each rotation of'the Geneva drive plate 138, and by angularly disposing the cam element 1% properly it;ca-n accorldingly be made to actuate the cam follower 189duringthe idling periods of the Geneva motion and thereby shift the crosshead' 135 forwardly in the body block recess 184 to move the back wall plate 182 outwardlyin'the compartment 103 for displacement of a booklet group G therefrom while a rest occurs in its intermittent circular movement.
The booklet groups G displaced from the compartments 103 in this manner are inserted in the course of the displacement in packing containers C presented by the container conveyor 105. The packing containers C are carried on the conveyor 105, as already mentioned, in carrying frames 106. These carrying frames 106 (see Figs. 15 and 16) consist of a back mounting plate 193 fixed to lugs 194 of a sprocket chain carrier 195 and having side retaining flanges 196 fixed thereon by screws 197, these flanges 196 being provided with elongated mounting apertures 198 so that they may be adjusted for different sizes of packing containers C. The top of the carrying frames 106 are open except for relatively short tip portions 199 provided on the side flanges 196 to position the containers C from above, while the bottom is formed by a hinged plate 200 carried on the back mounting plate 193 and normally supported in a level bottom closing position by a depending roller 201 arranged to ride a supporting rail or flange 202 that extends beneath the carrying frames 106 from the frame structure of the container conveyor 105.
The containers C are placed by hand in the carrying frames 106 to be advanced intermittently past the booklet handling compartments 103 at the adjacent station for receiving the booklet groups G as they are displaced therefrom in the manner already described above. The intermittent advance of the carrying frames 106 is actuated, as previously noted, through the chain and sprocket connection 151 running from the Geneva motion. This chain and sprocket connection runs to a sprocket wheel 203 at the container conveyor 105 which is mounted for rotation with a gear wheel 204 arranged to engage a mating gear wheel 205 that is carried on a common mounting shaft with a drive sprocket 206 for the carrying frame carrier chains 195, a similar idler sprocket being provided at 207 for these chains 195.
As the packing containers C approach the adjacent compartment station in the carrying frames 106 to receive the booklet groups G, the projecting lids of the containers C come in contact with a guide bar 208 mounted on brackets 209 extending from beneath the carrying frame roller supporting rail 202 (compare Figs. 4 and 15). This guide bar 208 runs from the brackets 209 to an elevated position over the adjacent compartment station so as to displace the container lids and thereby avoid any interference from the lid as the booklet groups G are inserted in the containers C.
After loading with a booklet group G displaced from an adjacent compartment 103, the intermittent advance of the loaded containers C is continued in the carrying frames 106 until the ejector station 107 is reached. At this point a break in the supporting rail 202 is provided as at 210 so that the hinged bottom plate 200 is allowed to drop downwardly as the carrying frame comes to rest below the ejector 107 which is a substantial duplicate of the previously described ejector mechanism 102 provided on the booklet conveyor 101, except that on the container conveyor 105 the ejector mechanism 107 is disposed vertically instead of horizontally (compare Figs. 4 and 16). Otherwise, the ejector mechanism 107 comprises, as before, an air cylinder 211 and an associated piston rod 212 carrying a pusher plate 213 adapted to move between the side flanges 196 for stripping the loaded containers C from the carrying frames 106. Beyond the ejector 107, the supporting rail 202 is formed with a developed lifting face as at 214 adapted to guide the bottom plate roller 201 back to a position riding on the supporting rail 202 and thereby close the hinged bottom plate 200 so that the carrying frames 106 are again ready to have empty containers C placed therein for loading with the booklet groups G as they are advanced to the adjacent compartment station.
The manner in which the ejector mechanisms 102 and 107 for the booklet and container conveyors 101 and 105 are actuated is illustrated schematically in Fig. 17. The air supply is delivered through a main line 215 which may be fitted in the usual manner with a gate valve as at 216, a filter 217, a pressure regulator 218 and indicating gage 219, and a lubricator 220. This main supply line 215 thus runs to branch lines 221 and 222 under the control of a solenoid valve 223, which is arranged for actuation from the previously mentioned micro switch 153 that is operated by the trip finger 152 carried on the Geneva drive shaft 139. The electrical connection between the micro switch 153 and the solenoid valve 223 may suitably consist of a standard D. C. line circuit 224, which should include a loading bridge as indicated at 225 across the micro switch to prevent any sustained are. With this arrangement it will be understood that the solenoid valve 223 remains normally closed until actuated by the micro switch 153. Upon rotation of the tripping finger 152, however, as timed by the Geneva motion, the normally open micro switch 153 is closed to close the line circuit 224 and thereby energize the solenoid valve 223 to release air through the branch lines 221 and 222 for operating the ejector mechanisms 102 and 107 at the proper time.
