9 Claims. (Cl. 53-186) The invention relates to packing machines and more specifically to machines for packing articles such as groups of cigarettes disposed in block-like form.

Single path packing machines for packing cigarettes in packets having a tray-like portion slidable within a shell are known. Such machines operate as so-called transverse packers in which cardboard blanks for forming the packets are transported in interrupted working steps from station to station transversely to the longitudinal axis of the cigarettes to be later contained therein. Chain conveyors having individual cells and which are moved in a step-wise manner are preferably used for transporting the cardboard blanks.

A number of cigarettes are grouped to form a so called cigarette block and enveloped in aluminium foil. This cigarette block is introduced to the transverse feed path of the packing material perpendicularly thereto at a predetermined region. a

If it should be desired to construct this known machine in a double path manner by providing two feed paths side by side, then the two paths must be supplied with the cigarette blocks from opposite sides. This would make two cigarette supply magazines necessary and consequently require two opera-tors, one posted at each side of the machine. Moreover, difierent cardboard blanks would have to be used for the right and left hand sides, since it would be necessary for the second path to be a mirror image of the first path. As a result of these disadvantages, such a two pathed machine would be commercially unpractical, since it has disadvantages without having any particular advantages.

The invention consists in a packing machine for packing articles, such as groups of cigarettes disposed in blocklike form, in packets, comprising means defining two feed paths for the articles, one feed path being disposed at a higher level than the other, each article-feed path being intersected by at least one transverse feed path, means being provided for feeding the articles along the articlefeed paths, means being provided for feeding packets or portions of packets along the transverse feed paths, the transverse feed path or paths which intersect one or the other of the article-feed paths passing over the other or the one article-feed path without intersection therewith.

When the packets are of a kind having a tray-like slide part which is to be slidably disposed in a shell part, preferably two transverse feed paths are provided for each article-feed path, one for feeding the tray-like slide parts and the other for feeding the shell parts.

The arrangement of the article-feed paths and the transverse feed paths may be such that articles fed along the article-feed paths are engaged by the packets or packet portions fed along the transverse feed paths and are then further transported along the article-feed paths for removal from the machine.

In this case, the article feed paths may be intersected by a common transverse removal path into which the packed articles are laterally displaced from the articlefeed paths, the transverse removal path having an inclined part adapted to the difference in height of the article-feed paths.

Alternatively, the arrangement of the article-feed paths and the transverse feed paths may be such that articles fed along the article-feed paths are engaged by the packets or packet portions fed along the transverse feed paths and are then further transported along the transverse feed paths for removal from the machine.

In order to make the invention clearly understood, reference will now be made to the accompanying drawings which are given by way of example and in which:

FIG. 20 is a plan view of the machine of FIG. 18;

FIG. 21 is a perspective view of a hinged cap boX such as is used with the machine of FIGS. 18, 19 and 20; and

FIG. 22 is a perspective view of a cigarette block for insertion in the box of FIG. 21.

The packing machine has two straight ahead feed paths for cigarettes, disposed atdiiferent levels, these being intersected by transverse feed paths for tray-like slide portions of packets and for shell portions after cigarettes have been supplied to the slide portions.

Referring now to FIGS. 1 and 9, the transverse feed paths are provided between frame walls 1, 2 and 3 and the straight-ahead feed paths are provided between frame part of a cigawalls 4, and 6 and extension walls 7, 8 and 9. The transverse feed paths are formed by conveyor chains having conveyor cells secured thereto, one path being formed by cells 11 and 13, and the other path at a higher level than the said one path, being formed by cells 12 and 14.

The housing walls 1, 2 and 3 are spaced apart and stiffened by means of traverses 15 and 16, 15 being a rod and 16 being a tube which is slid over the rod 15. The frame walls 4, 5 and 6 and the extension walls 7, 8 and 9 are spaced apart and stiffened by traverses 17 and 18. The frame walls 4, 5 and 6 are screwed to the housing wall 1, and the extension walls 7, 8 and 9 arescrewed to the frame walls 4, 5 and 6 respectively.

A main control shaft 19 for the transverse part of the machine is driven through spur wheels 20 and 21 from a lay shaft 22, the lay shaft 22 being driven by a V-belt pulley 23 from a pulley 24 by means of a V-belt 25, the pulley 24 being driven by a motor 26. The motor 26 is mounted on rails 27, which are secured to the frame walls 2 and 3 by means of angle members 28. The main control shaft 19 is mounted in bearings 29 fixed on the frame wall 2. r

A main control shaft 31 for the straight-ahead part of the machine is driven by a pair of bevel wheels 30 from the main control shaft 19. The shaft 31 is partly carried in the frame walls 1, 2 and 3, and partly in bearings 32 fixed on the frame wall 5.

A horizontal control shaft 33 (see also FIG. 8) is driven by a pair of bevel wheels 34, which are mounted in the frame walls 4, 5 and 6, from the control shaft 31.

A further, vertical, control shaft 36 mounted in bearings 37 which are fixed to the frame wall 5 is driven by a pair of bevel wheels 35.

The conveyor paths 11 and 12 are provided for the slide parts of the cigarette packets, the path 12 lying at a higher level than path 11. The cells 11 and 12 are guided in path plate parts 38, 39 and 40, and are connected together by endless roller chains 41, which are entrained over chain wheels 42 and 43 for the chain 41 carrying the cells 11, and chain wheels 46 and 47 for the chain 41 carrying the cells 12. The chain wheel 42 is mounted on a shaft 44, chain wheel 43 on a shaft 45, chain wheel 46 on a shaft 48, and chain wheel 47 on a shaft 49. The shaft 45 is mounted in the frame walls 1, 2 and 3, and carries a spur wheel 50 at its end. The shaft 49 is mounted in the frame walls 2 and 3 and carries a spur wheel 51. The spur Wheels 50 and 51 are commonly driven by a spur wheel 52 which is mounted on a shaft 53. A roller plate 56 having follower rollers 54 is mounted on the shaft 53 and is fixedly connected with the spur wheel 52. The roller plate 56 is periodically indexed by a switching cam 55 provided on the control shaft 19, so that the cell chains are driven forward by one cell pitch for each revolution of the control shaft 19. The conveyor paths 13 and 14 are provided for the shell parts of the cigarette packets, the path 14 being at a higher level than path 13, corresponding to the height of the path 12. The chains 41 carrying the cells 13 and 14 are entrained over chain wheels 43 and 47 of equal size provided on shafts 45 and 49, and are driven thereby, and over chain wheels 58 and 57, which are mounted on shafts 59 and 60. The drive of these chains is effected likewise by the control cam 55. The shafts 44, 48, 59 and 60 are fixed on slides 61 (see also FIG. 5), which are slidably mounted on rails 62 and with the aid of which the chains 41 can be tensioned.

The feeding of the cells 11 and 12 with carton blanks for the slide of the cigarette packet is eifected at the cell chain stations I and II. By means of a suction device 65 (see also FIGS. 5 and 6), in each case the lowermost flat carton blank 66 is drawn from magazines 63 and 64 and is bent over a roller 67 into the horizontal position. The leading end of the carton blank 66 thus comes to lie on a stationary roller 68, while a movable upper roller 69 is swung downwardly. By means of the two rollers 68 and 69, the carton blanks are then drawn out of the respective magazines 63 and 64, and fed into a roller path, which is provided with pairs of rollers 70, 71 and 70, 72 and are thus fed onto the cells 11 and 12. Plungers 73 and 74 press the carton blanks into the cells in such manner that their previously scored or previously perforated side parts project upwardly. The plungers 73 and 74 are fixed by means of a traverse 187 on a slide rod 188 guided in bearings 189 and 190. The slide rod 188 is moved upwards and downwards by drive means (not shown). The carton blanks are now transported by the cells 11 and 12. In the course of the transport, in each case front tips of the carton slide members are urged downwardly by stationary blades 75 (see FIG. 11), whereas the oppositely lying upper part of the tips are urged downwardly by blades 76 and are held in this position during the further transport. The cells 11 and 12 are thus loaded with prepared carton slide members.

Cigarette blocks, that is to say groups of cigarettes which have been wrapped in metal foil, are prepared in the straight-ahead part of the machine and are now introduced into the prepared slide carton members in the stations III and IV.

The straight-ahead part comprises the two stations III and IV, station IV lying higher than III. This part of the machine is fed by a common cigarette supply hopper (see FIG. 8) which comprises a wall 10, side walls 80, distributing parts 79, distributor shafts 81 which rotate to and fro, fan shaped channels 82 and supply chutes 77 and 78. The arrangement of the distributor shafts is disclosed in my patent specification No. 3,127,971.

The part of the hopper shown in line with station III shows the production of two individual blocks parallel to each other, each of 10 cigarettes, and the part shown in line with station IV shows the production of a single block of 20 cigarettes.

Pushing dogs formed by transverse rails 84 (see FIG. 1) fixed on chains 83 which are entrained over chain wheels 85 and 96 in each case supply the lowermost row of cigarettes from the supply chutes 77 and 78 over feed plates 86, until they fall in a layer onto a further somewhat lower lying plate 87 at the end of the plate 86. After in each case two layers have been provided one on the other, pushing dogs 89 which are pivotally linked on chains 90, intermittently advance the cigarette blocks 91 thus formed.

A light easily displaced abutment 88 brings each cigarette block 91 into engagement against the pushing dog so that individual cigarettes do not project.

The claims are driven by chain wheels 96 and are entrained over the same. The front chain wheels 96 are arranged in pairs on drive shafts 97, whereas the rear chain wheels 96 are provided on idle shafts 98.

The front shafts 97 carry spur wheels at their ends which mesh with a spur wheel 100 on a shaft 101, this meshing with -a spur w-heel 106 on shaft 102. An indexing disc 103 with follower rollers 104 is provided on the shaft 102. This indexing disc 103 is intermittently driven by a control cam 105 provided on the control shaft 31, so that the pushing dogs 89 of the chains 90 are driven forward in each case by one step for each revolution of the control shaft 31. In the end position of advance. by the pushing dogs 89, the cigarette blocks pass onto an elevating plate 107 which is fixed to a push rod 108 and are there lifted to the level of plates 109 and 110.

Previously, the cigarette blocks 91 have been pushed by means of the pushing dogs 89 at the station E into engagement with a piece of metal foil, for example aluminimum, which is taken from a supply roll 95, this being formed in a U-shaped manner around the cigarette block, in a manner known per se.

The feed arrangement for the metal foil is known per se and consists of an advancing roller pair 94, cutting blades 93, a deviating roller 110, a compensating pendulum 111 and an advancing roller pair 112.

Whereas the advancing roller pair 112 continuously operates, the compensating pendulum 111 takes up the drawn off length of foil, the intermittently operating advancing rollers 94 and the cutting blades 93 are arranged at different heights, corresponding to the difference in height of the feed plates 87.

On the way from station E to station F, the lateral folds on the metal foil wrapping are effected by means of stationary folding elements or blades 113 (see FIG. 11), so that at station F wrapped blocks which are closed on five sides but which are rearwardly open are present. The pushing dogs 89 are swung rearwardly at station F by means of levers 114, whereupon lateral folding devices 118, lower folding devices 115, and upper folding devices 116 complete the end folds (see FIGS. 2, 3 and 4), while an abutment 117 holds the block in position against the folding pressure. Thereafter, the pushing dogs 89 at station F are again swung upwardly by means of the levers 114 and the blocks 91 are transported further thereby.

After elevation onto plat- forms 109 and 110, by the elevating plates 107, the blocks 91 are pushed by means of transport hooks 119 at stations III and IV into the prepared slide carton parts which lie in the cells 11 and 12.

The transport hooks 119 have rollers 12-7 at lateral arms thereof, which run over guide rails 128 and 129 and hold them in position. The transport hooks 119 are moreover provided on roller chains 120 which are guided over and driven by, in each case, four chain wheels 121. These transport chains 120 are driven without interruption, that is to say they run continuously. The drive of the lower chain is effected by a pair of spur wheels 131 and by a further roller chain 130 and chain wheels 122 and 123. Chain wheel 123 is provided on a shaft 126 which is driven by a pair of bevel wheels 134 from a chain lwheel 132 through a chain 135 and a chain wheel 133 provided on the control shaft 31 (FIG. 1). The upper chain 120 is driven through a pair of spur wheels 136 likewise from the shaft 126.

Opposite to the region of the cigarette block production in stations III and IV, devices for the removal and feeding of shell or sleeve carton parts with respect to the cells 13 and 14 are provided. By means of pushing dogs 139 in each case the lowermost flatly lying shell, which is already glued and formed into a collapsed box shape, is removed from magazines 137 and 138 (see FIGS. 1 and 2) and intermittently fed in the direction of the arrow A. Further pushing dogs 140 move the collapsed shells in each case by one station forwardly. The collapsed shells, after leaving the magazine, are erected by an arrangement disclosed in my German patent specification No. 1,097,-

889, and are introduced into the cells 13 and 14. The,

pushing dogs 139 and 140 are provided on slides 141 which have different lengths corresponding to the spacing of the delivery regions from the magazines 137 and 138.

The cells 11 and 13, and 12 and 14 move parallel up to stations V and VI (see FIGS. 9 and Further transport chains 144 having transport hooks 142 are provided here, which introduce the slide portion of the packet, together with the aluminium foil wrapped cigarette block present therein, into the allocated shell by means of tapered guides 145 and moreover convey the finished packet onto a delivery plate 146 of the machine.

The chains 144 for station IV, run over chain wheels 147 from a frame 166 up to a frame 163. These chains are guided over a supplementary chain wheel 150 in order that the transport hooks 142 can follow the inclined guide path 172. Thus the packets produced in the lower path are brought up to the level of the delivery plate 146. The chains for the station V run over chain wheels 147 from a frame 165 up to a frame 162. The drive of the chain wheels is effected in common through spur wheels on a shaft 178 and spur wheels meshing therewith on a shaft 179 and through a common intermediate spur wheel 149 on a shaft 180. A chain wheel 174 is provided on the shaft 179, and is driven by a chain 173 from a further chain wheel 181 on the control shaft 19. The drive of the chains 144 is effected continuously. The frames 162, 163, 164, and 166 are arranged in pairs and are mutually braced by means of traverses 170, 171, 167, 168 and 169. The transport hooks 142 have rollers 177 on lateral extensions, the rollers being supported on guides 160 and 161 and being linked with central studs 182 on the chains 144. The transport hooks 142 remain always in their suspended position.

The packet slide parts in the cells 11 and 12, containing the cigarette blocks, are further handled on the way from station III to station VI, or from station IV to station V respectively so that the still open introduction side is raised up by stationary blades 184 and 185 (FIG. 11) and the upper carton tip is folded over inwardly. In this manner, the slide part is completely introduced into the packet shell by means of the transport hooks 142 and the tapered guide 145.

Since the paths for the cells 12 and 14 lie higher than the paths for the cells 11 and 13, the supply of the aluminium-wrapped cigarette blocks to station IV by movement above the cells 11 and 13 on the way to the cells 12 is possible. Furthermore, the supply of the shells from station III from magazine 139 to the cells 13 by movement below the cells 12 is possible. Furthermore, the beginning of the paths of stations I and II are so displaced relatively to each other that at station I the supply of the slide carton part from magazine 63 to the cells 11 is possible. The same is the case for the ends of the paths formed by the cells 13 and 14 so that the delivery of the finished packets from station VI from the path for the cells 13 is readily possible without hindrance.

The difference in height of the paths for the cells 11 and 13 relative to the paths for the cells 12 and 14 is a basic feature of the invention. The way in which the paths are fed may vary, depending at which side of the machine the magazines 63, 64 and 137, 138 are to be arranged.

An alternative arrangement is illustrated in FIGS. 13, 14 and 15. Whereas in the first embodiment the shell magazines 137 and 138, the slide magazines 63 and 64, and the cigarette hopper 10 are arranged in front of the respective feed paths, in the alternative arrangement of FIGS. 13, 14 and 15, the shell magazines, the slide magazines and the cigarette hoppers are arranged on one side of the machine, an outlet passage 191 for finished packets being provided at the other side. The finished packets from both paths are brought together in the passage 191 and for convenience in final wrapping are disposed vertically one behind the other, this being effected by fixed blades 192.

The path for the cells 13 runs from station III below that of the slide supply device. The paths for the cells 11 and 13 run to station V below the path along which the cigarette blocks are fed. It is thus possible to work in two paths, using a common cigarette supply hopper for both paths, the supply of the packet blanks being effected in common from the same side or selectively from one or the other side of the machine.

The packet which is produced by the machine of FIGS. 1 to 12 or 13 to 15, is shown in FIGS. 16 and 17, FIG. 16 showing the slide part 194 and FIG. 17 showing the shell part 195.

An analogous problem arises in connection with cap box packing machines for cigarettes. These packing machines also operate according to the intersecting feed path system, and the production of double pathed cap box packing machines is subject to the same difficulties as for slide and shell transverse packing machines. The system of differently elevated packing paths according to the invention, can also be used with the same result in this case.

In FIGS. 18, 19 and 20, such a double pathed intersecting feed cap box packing machine for cigarettes is illustrated, a cap box and its contents being shown in FIGS. 21 and 22 respectively.

The machine has magazine chutes 201 and 202 in which the empty boxes are inserted and from which they are removed by carriers 203 of transverse transport chains 204 and 205 and introduced into the packing path.

On the way from station I to station II and from station IV to station V respectively, the lids of the cap boxes are opened, so that at stations II and V they are disposed as illustrated in FIG. 21. On the way from stations VII to station II and stations VIII to station V, the inner part is produced, as is shown in FIG. 22. Upper plungers 206 and 207 then press the inner part of FIG. 20 from above into the box of FIG. 21, so that the metal foil part 209 and 210 extends upwardly in an L-shape. At one of the next stations, the foil part 208 is lifted up by fixed rails so that the foil part 210 can be pushed below it, this being efiected by known folding means not illustrated. Thereafter, at further stations the foil part 208 is released, and the lid 211 of the cap box is closed, whereupon the finished, filled, boxes are stacked in chutes 212 and 213 at stations III and VI or are removed in another known manner.

The above-outlined construction and operation is possible because of the difference in height of the packing paths provided by the conveyor chains 204 and 205 and due to the fact that thepaths II to III and stations VIII to V are so disposed that one path can be guided above the other.

The common cigarette supply hopper for both paths is indicated by reference numeral 217, the supply chutes 216 thereof being of different heights corresponding to the different feed path heights. Continuously revolving chains 214, provided with transverse bars 215 remove in each case the lowermost cigarette layer from the supply chutes 216 and convey this onto guide plates 263. At the end of these guide plates, the cigarettes fall in layers onto the lower lying guide plates 229. Pushing dogs 219 on the permanently revolving chains 264 then push the thus formed cigarette block 266 after the required number of layers has been collected, onto a metal foil section 265. The metal foil section 265 is taken from a roll 220, winding rollers 221 removing the required length and supply rollers 226 periodically supplying this amount. During a period of rest of the supply rollers 226, cutters 227 and 228 out the foil section. At this instant, a cigarette block 266 arrives in front of the cut section and is pushed thereagainst so that the foil section is formed in a U-shaped manner about the cigarette block.

The cigarette block 266 which is now enveloped in U-shaped manner, is introduced into a pocket 233 which is movable to and fro and a rod 234, when the pocket is in its lowermost position, whereupon a pushing dog 219 tips rearwardly in known manner. The pocket 233 moves into its uppermost position and, for the front path V0, a pushing member 231 provided on an arm 232 pushes the cigarette block out of the pocket 233 in the position II above the path V0, where the prepared cap box of FIG. 19 lies. The plunger 206 then presses the cigarette block of FIG. 22 into the opened box.

For the rear path Hi, a transport chain 235 serves for feeding the cigarette block from the pocket 233 above the opened box in position V above the path Hi, since transport hooks 236 provided on the chain 235, and which are stabilized by means of rollers 237 and guided thereby, are brought into such a position in which the cigarette block of FIG. 22 is pressed by the plunger 207 into the open box of FIG. 21.

The further operation of the machine is similar to that of the machine of FIGS. 1 to 12.

The drive of the intermittently advanced chains 243 is effected by an indexing cam 251, which is provided on a common control shaft 252 and which drives an indexing plate 250 in such manner that for each control shaft revolution the plate 250 is rotated through a fixed angle of for example 60. Spur wheels 248 and 246 and 247, transfer the rotary movement onto the chain wheels 245 over which the chains 243 are entrained, the chains 243 being also guided over chain wheels 244.

The drive of the main control shaft 252 is effected by a motor 258 which is provided on a plate 259 in the machine frame 253. By means of a V-belt pulley 257 and a V-belt pulley 256 is driven from the motor shaft. A pinion 255 is provided on the same shaft as the pulley 256, and meshes with a spur wheel 268 on a control shaft 254. This control shaft 254 drives the control shaft 252 through a pair of bevel wheels 267.
