Description

SPECIFICATION Cigarette production and packaging installation This invention relates to a cigarette production and packaging installation.

In particular, this invention relates to an installation comprising a cigarette forming machine, and a packaging machine connected to the exit of said forming machine, its main purpose being to enable each of said two machines to operate at full capacity not only when the other machine is operating at a reduced production rate but also when it is completely halted.The present invention provides a cigarette production and packaging installation, comprising a cigarette forming machine, a packaging machine, and conveyor means for directly feeding the cigarettes from the exit of said forming machine to the inlet hopper of said packaging machine, said installation also comprising an auxiliary conveyor unit which at one end communicates with said conveyor means and at the other end communicates with said inlet hopper and comprises filling means arranged to receive the cigarettes produced by said forming machine and to fill a plurality of containers with them in succession, and overturning means for overturning the cigarettes contained in said containers into an auxiliary hopper communicating with said inlet hopper; said auxiliary unit also comprising at least one inlet-exit station for said containers, and at least one trolley arranged to cooperate with said station and comprising an upper frame and a lower frame each arranged to support a plurality of said containers; said station comprising an upper conveyor and a lower conveyor for said containers, actuator means being provided for vertically moving one or other of said upper and lower frames, independently of each other, between an upper position disposed above the level of said upper and lower conveyor respectively, and a lower postion disposed below the level of said upper and lower conveyor respectively.Further characteristics and advantages of the present invention will be apparent from the description given hereinafter with reference to the accompanying drawings, which show two nonlimiting embodiments thereof, and in which: Figure 1 is a block diagram of an installation according to the present invention; Figure 2 is a block diagram of an improved embodiment of the installation of Figure 1; Figure 3 is a diagrammatic view showing the installation of Figure 1 in elevation, with parts in section and parts removed for clarity; Figure 4 is a diagrammatic plan view of a detail of Figure 3; Figure 5 is a diagrammatic view showing a side elevation of a detail of Figure 4; Figure 6 is a perspective view to an enlarged scale of a detail of Figures 1 to 4;; Figures 7 and 8 are diagrammatic views of the detail of Figures 4 and Sand the detail of Figure 6 at two different moments of operation; Figure 9 is a diagrammatic elevation of the installation of Figure 2 with parts in section and parts removed for clarity; and Figure 10 is a perspective view to an enlarged scale showing a detail of Figure 9 during one stage of its operation.

Figure 1 shows a cigarette production and packaging installation 1 comprising a cigarette forming machine 2, and a packaging machine 3 directly connected at one end to the forming machine 2 and at the other end to an auxiliary unit indicated overall by 4. This latter constitutes part of the installation 1, and comprises in its turn a filling unit 5, the inlet of which is connected to the exit of the forming machine 2 in parallel with the packaging machine 3, and is arranged to receive cigarettes in order to feed them into so-called "box" containers of known form indicated by 6 (Fig. 3).The auxiliary unit 4 also comprises a loading and unloading unit 7 comprising a first inlet connected to the exit of the filling unit 5, and a first exit connected to a rotatable head 8 constituting part of the auxiliary unit 4 and arranged to receive full containers 6 from the unit 7, to overturn them in such a manner as to feed the relative cigarettes to the packaging machine 3 in parallel with the direct feed from the forming machine 2, and to return the empty containers 6 to the unit 7. This latter comprises a further exit through which the full containers 6 can be fed to a trolley 9 forming part of the auxiliary unit 4 and mobile between the unit 7 and a packing area or preferably a store 10 in order to transfer the full containers 6 in both directions between the unit 7 and the store 1 0.

In a preferred embodiment of the installation 1 shown in Figure 3, the exit of the forming machine 3 is constituted by a channel 11 defined in known manner by facing belt conveyors 12, which are arranged to feed cigarettes in bulk to a channel 13, also defined in known manner by facing belt conveyors 14 and communicating at one end with the inlet hopper 1 6 of the packaging machine 3 and at the other end with a known variable capacity store 1 6.

At the inlet to the hopper 15, the channel 1 3 communicates with a channel 17, defined in known manner by belt conveyors 1 8 mobile in both directions and connected to two channels 1 9 and 20, of which the first is defined by mobile belt conveyors 21 for feeding the cigarettes from the channel 1 7 to the hopper 22 of the filling unit 5, and the second is defined by mobile belt conveyors 23 for feeding to the channel 1 7 the cigarettes discharged from the rotatable head 8 into the inlet hopper 24 of the channel 20.

As shown in Figures 4 and 5, the filling unit 5 comprises two conveyors 25 and 26 (Fig. 5) disposed facing each other at a level below the level of the hopper 22 and to the side thereof, and extending parallel to the conveyors 21 in order to connect the filling unit 5 to the unit 7.

This latter comprises an inlet-exit station for the containers 6, comprising two overlying bidirectional conveyors 27 and 28 extending perpendicular to the conveyors 25 and 26. In particular, the conveyor 27 is disposed at the same level as the conveyors 25 and 26, and is arranged, when moved towards these latter, to successively feed the empty containers 6 on one end of the conveyor 25.

When it recieves an empty container 6, the conveyor 25 conveys it into the filling unit 5 in a position facing the hopper 22, into the path of a pusher 29 which is mobile from and towards the hopper 22 and is arranged to engage with said container 6 in order to move it on to the conveyor 26 in a position facing the hopper 22.

The said empty container 6 is filled in known manner by a pusher 30 opposing the pusher 29 and mobile through the hopper 22 in order to transfer the cigarettes from this latter to the said empty container 6, which in known manner is open on the side facing the hopper 22 and is retained in a position in front of it by the pusher 29. During the operation of the pusher 30, any flow of cigarettes to the hopper 22 is prevented by known shut-off means, not shown, disposed at the end of the channel 1 9.Once filled, each container 6 is fed from the conveyor 26 into the unit 7 in a position facing the conveyor 27, in which said container 6 can be picked up by a substantially vertical bidirectional elevator device 31 (Fig. 5) arranged to move the containers 6 between the aforesaid position, hereinafter indicated by the term "lower position", an intermediate facing position coplanar with the conveyor 28, and an upper position aligned with the rotatable head 8.

This latter, as shown in Figure 3, is disposed below one of the ends of a guide 32, the other end of which extends above said upper position and slidably supports a fork 33 arranged to move the containers 6 between the rotatable head 8 and said upper position.

As shown in Figure 5, the elevator device 31 cooperates with two pushers 34 and 35 arranged to laterally engage with respective containers 6 disposed in said lower position and in said intermediate position respectively, in order to push them on to the conveyor 27 and conveyor 28 respectively.

In the unit 7, the conveyors 27 and 28 are supported (Figure 5) between the arms of respective fork brackets 36 and 37 having a width less than the length of the containers 6.

Consequently when these latter are disposed in a transverse position on the conveyors 27 and 28, their opposing ends project outside the brackets 36 and 37 so as to grectiy simplify the depositing of the containers 6 on the conveyors 27 and 28 and their withdrawal from them.

The said depositing and withdrawal of the containers 6 are carried out by means of the trolley 9, which is shown in detail in Figure 6 and comprises two vertical side frames 38 connected together by a base plate 39 provided lowerly with brackets 40 which rotatably support two axles 41 each fitted with two wheels 42. The trolley 9 comprises two further frames 43 and 44 disposed horizontally, the first above the second between the two frames 38 and at a distance from each other which exceeds the height of the containers 6.

Each frame 43, 44 comprises two longitudinal lateral rods 45, each of which is connected to the adjacent frame 38 by a pair of cranks 46 which together with the relative rod 45 define an articulated quadrilateral.

The rods 45 of each frame 43, 44 are disposed at a distance apart which exceeds the width of the brackets 36 and 37, and each supports an undulated element arranged to define, together with the undulated element of the other rod 45 of the same frame 43, 44, a plurality of boxes each arranged to receive a container 6. In particular, as shown in Figure 6, the rods 45 of the upper frame 43 each support an undulated element 47 substantially in the shape of a saw-tooth wave, of which the teeth 48 define a plurality of boxes arranged to receive a plurality of full containers 6, disposed slightly inclined backwards in order to prevent cigarettes escaping from their front open side.The rods 45 of the lower frame 44 each support an undulated element 49 substantially in the form of a square wave, of which the teeth 50 define a plurality of boxes arranged to receive a plurality of empty containers 6 disposed in a vertical position.

Each frame 43, 44 is provided with actuator means, which in the example illustrated are shown diagrammatically as a hand grip 51, arranged to allow it to move, by rotating the cranks 46, between a lowered position shown in Figure 6 and a raised position. Conveniently, each frame 43, 44 is provided with at least one stop element 52, which by cooperating with one of the frames 38 acts as a locking element for the relative frame 43, 44 when this latter is in said lowered position, whereas it acts as a limit stop when said frame 43, 44 is moved into said raised position. In this position, each frame 43, 44 is held at rest by a locking device which in the example illustrated is shown diagrammatically as a compass element 53 disposed between each crank 46 and the relative frame 38.

The operation of the installation 1 will be described with reference to Figures 1 to 6, and, in particular, to Figures 7 and 8, relative to the case (CASE I) in which the packaging machine 3 stops, and the case (CASE II) in which the cigarette forming machine 3 stops, all other intermediate cases involving one or other of the machines 2 and 3 operating at reduced capacity being easily deduced from the aforesaid two extreme cases.

CASE 1 In the installation 1 , the stoppage of the packaging machine 3 for any reason does not automatically lead to the stoppage of the cigarette forming machine 2, as the cigarettes produced by this latter can be automatically fed to the store 10 for future use (see CASE II), or to a further unused packaging machine (not shown) which may be present, or simply unloaded on to one or more trolleys if the stoppage of the packaging machine 3 is of short duration.

When the packaging machine 3 stops, the cigarettes arriving in bulk from the channel 13 generate an overpressure at the mouth of the hopper 15, in response to which a sensor 54 (Figure 3) operates the conveyors 18 and 21 in such a manner as to feed the cigarettes produced by the machine 2 to the hopper 22 through the channels 13, 17 and 19.

At the same time, the filling unit 5 and unit 7 are started up, on the conveyor 27 of which there normally rest a number of empty containers 6 (Fig.

5), and on the conveyor 28 of which there normally rest a number of full containers 6.

As stated heretofore, the conveyor 27 is operated such as to feed an empty container 6 to the conveyor 25, which moves it into a position facing the pusher 29. By the action of this latter, said empty container 6 is transferred on to the conveyor 26, and when filled by virtue of the emptying of the hopper 22 by the pusher 30, is fed by the conveyor 26 to the elevator device 31 into said "lower position".

Following the operation of the device 31, said container 6 is raised from the "lower position" to said "intermediate position", and then transferred on to the conveyor 28 as a result of the operation of the pusher 35.

The operational cycle as heretofore described is repeated until all the originally emptry containers 6 disposed on the conveyor 27 have been filled and transferred on to the conveyor 28, and can be continued only if the full containers 6 are removed and replaced by other empty containers 6.

The operations involved in removing the full containers 6 from the conveyor 28 and replacing them by new emptry containers 6 on the conveyor 27 are illustrated diagrammatically in Figure 7, and are carried out by means of a trolley 9 in the manner described hereinafter.

In order to more easily understand the operations described hereafter, it should be noted that, as stated, the width of the brackets 36 and 37 is less than the distance between the two undulated elements 49 and 47 respectively.

Consequently, the trolley 9 can be disposed in such a manner that the brackets 36 and 37 penetrate into the space between the frames 38, and do not interfere with the frames 43 and 44 during their vertical movement. Furthermore, the cranks 46 are disposed and sized such that the undulated elements 47 and 49 are disposed, when in the lowered position, at a level less than that of the upper branch of the relative conveyors 37 and 36. Conversely, the level of the undulated elements 47 and 49 when disposed in their raised position is higher than that of the upper branch of the relative conveyors 37 and 36.

As stated, the full containers 6 are removed and substituted by empty containers 6 by means of a trolley 9, of which the upper frame 43 is completely unloaded, whereas the lower frame 44 is completely occupied by empty containers 6. The trolley 9 is brought up to the unit 7 so as to receive the brackets 36 and 37 thereof between its frames 38, and is arranged with its upper frame 43 in the lowered position so as not to interfere with the full containers 6 disposed on the conveyor 28, and its lower frame in the raised position in order to prevent the empty containers 6 supported by it from interfering with the conveyor 27 as the trolley 9 is moved up to the unit 7.

When the trolley 9 has been disposed in the position illustrated in Figures 4 and 7, the lower frame 44 is moved into the lowered position so as to deposit the full containers 6 on the conveyor 27, and the upper frame 43 is raised so as to raise the full containers 6 from the conveyor 28, their other ends remaining engaged between the teeth 48, the inclined sides of which enable the full containers 6 to lie in a backwardly inclined position so as to prevent cigarettes escaping from the open front side thereof.

By removing the trolley 9, it is then possible to remove the full containers 6 and leave the empty containers 6 on the conveyor 27. The full removed containers 6 can be fed to the store 10 for subsequent use, or can be kept on the trolley 9 which, in this case, itself acts as a store.

CASE II In the installation 1, if the cigarette forming machine 2 stops for any reason, it does not automatically lead to stoppage of the packaging machine 3, as this latter can be fed by the auxiliary unit 4 with cigarettes taken from the store 10 or brought directly by a plurality of trolleys 9. In this respect, stoppage of the cigarette forming machine 2 results in the operation of the unit 7, on the conveyor 27 of which there normally rest a number of empty containers 6 (Figure 5), and on the conveyor 28 of which there normally rest a number of full containers 6.

The conveyor 28 is operated in such a manner as to feed said full containers 6 in succession to the elevator device 31 in said "intermediate position".

As shown in Figure 8, when the device 31 has received a full container 6, it moves it into said "upper position" between the arms of the fork 33, which slides along the guide 32 to feed it to the rotatable head 8, This latter, as is known (see Italian patent No. 779,386 of the same applicant), is arranged to simultaneously support two containers 6 (Figure 5), of which one is disposed in an upright position between the arms of the fork 33, and the other is disposed in an overturned position (Figure 3) above the hopper 24.

When the rotatable head 8 rotates through 1 80o, it moves said full container 6 into the overturned position, so pouring its contents into the hopper 24, and moves the other container 6, which is already empty and present on the head 8, into an upright position between the arms of the fork 33, which moves along the guide 32 to feed it to the elevator device 31 in said "upper position".

The container 6 is then made to descend by the device 31 from the "upper position" to the "lower position", and is then moved on to the conveyor 28 by the pusher 34.

The described cycle is repeated until all the originally full containers 6 disposed on the conveyor 28 are fed to the conveyor 27 after pouring their contents of cigarettes into the hopper 24, from which the cigarettes are fed to the hopper 1 5 through the channels 20 and 1 7.

Further operation of the packaging machine 3 is successively ensured by the trolleys 9, by means of which it is possible to feed new full containers 6 on to the conveyor 28 and withdraw empty containers 6 disposed on the conveyor 27. In order to carry out the aforesaid operations, a trolley with its upper frame 43 loaded with full containers 6 and its lower frame 44 completely unloaded is disposed in the position shown in Figure 4 in such a manner as to receive the brackets 36 and 37 of the unit 7 between its lateral frames 38. The trolley 9 is brought up to the unit 7 with its upper frame 43 in the raised position, so that the full containers 6 supported by it pass above the unloaded conveyor 28, and with its lower frame 44 in the lowered position so that it passes below the empty containers 6 disposed on the conveyor 27.

When the position of Figure 4 has been reached, the upper frame 43 is moved into the lowered position, so as to unload the full containers 6 on to the conveyor 28, and the lower frame 44 is moved into the raised position in order to lift from the conveyor 27 the empty containers 6 previously disposed on it. The trolley 9 is then removed from the unit 7 to leave its conveyor 28 completely loaded with full containers 6, and its conveyor 27 completely unloaded. In this manner, the unit 7 is able to continue to supply cigarettes to the packaging machine 3 by way of the rotatable head 8, the hopper 24 and the channels 20 and 17, and the loading-unloading cycle heretofore described and carried out by means of the trolley 9 is repeated until the cigarette forming machine 2 is again in operation.

From the aforegoing, it will be noted that the installation 1 heretofore described is able to ensure continuity of operation of either of the machines 2 and 3 in the case of stoppage of the other, and is obviously able to compensate for any partial reduction in the production capacity of either of said two machines relative to the other. It should however be noted that the use of the installation 1 is normally advisable when the channel 13 which connects the exit channel 11 of the cigarette forming machine 2 to the inlet hopper 1 5 of the packaging machine 3 is of simple construction and relativity short length, i.e. when the channel 13 is of extremely high reliability.

However, all the drawbacks deriving from possible difficulties which might arise along the channel 13 are obviated, as will be apparent hereinafter, by the improved embodiment of the invention illustrated by way of non-limiting example in Figures 2, 9 and 10.

Figure 2 shows an installation 55 for producing and packaging cigarettes, in which a cigarette forming machine 2 is connected to a packaging machine 3 both directly and by way of an auxiliary unit 4' comprising a filling unit 5' arranged to receive cigarettes from the cigarrette forming machine 2, and to fill a plurality of containers 6 with them in succession (Figures 9 and 10).

The unit 4' also comprises a loading-unloading unit 7' arranged to receive the full containers 6 from the unit 5', and to unload them into the packaging machine 3 with the aid of a rotatable head 8. The auxiliary unit 4' finally comprises a trolley 9' substantially identical to the trolley 9 described heretofore, and able to transfer containers 6 from the units 5' and 7' both directly and by way of a store 10.

As shown in Figure 9, the filling unit 5' is disposed upstream of the channel 11 which is arranged to feed cigarettes in bulk to the channel 1 3 feeding the hopper 1 5 of the packaging machine 3, and is arranged to receive cigarettes 56 (Figure 10) directly from a horizontal conveyor 57 by means of which the cigarettes 56 leaving the cigarette forming machine 2 are moved forward individually into side-by-side positions transversely to their axis.

The filling unit 5', which is of substantially known type, is illustrated in particular in Figure 10, and comprises a loading-unloading station for the containers 6 comprising a lower conveyor 58 and an upper conveyor 59, the former disposed below and the latter above the level of the conveyor 57.

The conveyors 58 and 59 are disposed facing each other at the exit end of the conveyor 57, and extend perpendicular to this latter at substantially identical levels to those of the conveyors 27 and 28 respectively of the unit 7 of the installation 1.

Furthermore, the conveyors 58 and 59 have transverse dimensions which are substantially identical to those of said conveyors 27 and 28, and such as to enable them to be inserted between the lateral frames 38 of the trolley 9', the structure of which is substantially identical to that of the trolley 9 of the installation 1, and is indicated by the same reference numerals. By comparing Figures 10 and 6, it is apparent that the only difference between the trolleys 9 and 9' is that in the trolley 9' the square wave undulated elements 49 are supported by the upper frame 43, while the sawtooth wave undulated elements 47 are supported by the lower frame 44.

As shown in Figure 10, the filling unit 5' comprises an elevator device 60 which itself comprises a vertical rack 61 mobile in alternate vertical directions under the action of a pinion 62, and provided with a transverse bracket 63 mobile in a vertical plane and extending between the conveyor 57 and those ends of the conveyors 58 and 59 which face this latter. The bracket 63 is arranged to receive in succession the empty containers 6 disposed on the upper conveyor 59, and to convey them one-by-one on to the lower conveyor 58 by passing them, with their open side frontwards. to the end of the conveyor 57. During this passage, the cigarettes 56 arriving on the conveyor 57 are thrust in successive groups by a pusher 64 into the container 6 supported by the bracket 63.The pusher 64 has a width equal to the inner width of the containers 6, such that each of said groups of cigarettes corresponds to one layer of cigarettes inside a container 6. The conveyor 57 and rack 61 are synchronised such that when passage in front of the conveyor 57 is termined, the container 6 disposed on the bracket 63 is completely full. When in operation, a roll of empty containers 6 supported by the upper frame 43 of the trolley 9' is deposited on to the conveyor 59 by moving said upper frame 43 from an initial raised position to the lowered position. The conveyor 59 feeds said empty containers 6 in succession to the elevator device 60, which transfers them on to the conveyor 58, to which the containers 6 arrive full.Consequently, at the end of the operational cycle as heretofore described, all the empty containers 6 initially disposed on the conveyor 59 are located on the conveyor 58 in a full state, and from which they are withdrawn by moving the lower frame 44 from an initial lowered position to the raised position.

The full containers 6 disposed on the lower frame 44 of the trolley 9' can be fed either to the store 10 or directly to the unit 7'. This latter is substantially identical to the unit 7, from which it differs almost only in that it comprises an elevator device (not shown) similar to the device 31, but having only two stop positions, of which one is aligned with the lower conveyor (not shown) of the unit 7', and the other is aligned with the upper conveyor (not shown) thereof.

When in operation, a trolley 9' with its lower frame 44 loaded with full containers 6 received from the filling unit 5' (this would normally be the case if there is any failure of the conveying devices disposed along the channels 11 and 13), or from the store 10 (this would normally be the case if there is any failure of the cigarette forming machine 2, the store 10 having been loaded during a previous stoppage of the packaging machine 3) unloads said full containers 6 on to the lower conveyor (not shown) of the unit 7' by moving the lower frame 44 from its initial raised position to the lowered position. By means of said elevator device (not shown) of the unit 7', the full containers 6 are transferred to the level of the upper conveyor (not shown) of the unit 7', and fed to the rotatable head 8 by means of the fork 33 slidable along the guide 32.When they have been emptied, the containers 6 are returned by the fork 33 to the unit 7', and fed to the upper conveyor (not shown) thereof, from which they can be removed by moving the upper frame 43 of the trolley 9' from its initial lowered position to its raised position.

On being overturned by the rotatable head 8, the full containers 6 pour their contents into a hopper 65 communicating with the hopper 1 5 by way of a feed channel 66 defined by opposing conveyor belts 67.

The complete operation of the installation 55 does not require further explanation beyond that already given, as it is easily deduced from the operation of the installation 1 as heretofore described. However, it is important to emphasise the fact that by using one or more trolleys 9 and a plurality of containers 6, the installation 55 is perfectly able not only to compensate for any reduction in production capacity of one of the machines 2 and 3 and to keep each of said two machines active should the other stop, but also to maintain its own production rate unchanged in the case of stoppage of the feed systems disposed along the channels 11 and 13 which directly connect the cigarette forming machine 2 to the packaging machine 3.

Within the principle of the invention, numerous modifications can be made to the installations 1 and 55 which have been described by way of nonlimiting example, without leaving the scope of the inventive idea.

In particular, the means for supporting and vertically moving the frames 43 and 44 could be different from those described.
