Definitions
- the invention relates to a packaging machine of the type in which packaging cases (folding boxes) of cardboard or corresponding material are extracted from a magazine, the cases are erected and placed in holders on an endless conveyor track, along which track processing stations are arranged for performing necessary process operations on the cases, including filling these in order to provide finished cases, filled with product, in a delivery station of the packaging machine.
- Machines of this type have been on the market for a long time, and one type of such machines has been produced since the 1950s and has been marketed by the applicant of the present invention. This type of machine is marketed under the trademark "EXPRESSO” and is well known within the purchasing circle.
- the packaging cases which the machine delivers are cases without any type of inner bag and the cases are sealed powder-tight by means of a bottom which has a membrane closure and a correspondingly closed top, said cases having found widespread use, not only for powder type products but also for deep-frozen products, e.g. fruit juices.
- This case type is a leader from an environmental and recycling viewpoint and gives extraordinary possibilities for fulfilling present and future environmental requirements.
- This machine type works horizontally and the cases are transported to the different processing stations by an endless metal ribbon, chain or the like, which runs over two chain wheels, one of which is driven by a drive motor.
- the conveyor track has two opposed straight track portions and, in principle, processing of the bottom of the case is performed along one portion, filling of the cases is done in the connecting part-circular portion, and in the following straight conveyor portion the case tops are completed for feeding the cases out in a delivery station at the end of this straight conveyor portion.
- camshafts in the machine frame connected via a gearing arrangement to the drive motor; a lower horizontal camshaft and an upper horizontal camshaft.
- cam discs On these shafts there are cam discs which manoeuvre the processing tools in the various processing stations.
- the machine according to Swedish laid-open application 390 154 can be mentioned.
- the machine according to said publication is a further development of the original concept and has the purpose of making continuous operation also possible.
- the machine is however equipped with the traditional conveyor for the case holders and it has the conventional arrangement of drive shafts and camshafts.
- the problem with these known conveyors is that in certain environments they require a great deal of servicing, e.g. in the form of lubrication and cleaning, and in certain cases they can break down even to the point of destruction.
- GB patent no. 1233818 operates in a circular "conveyor track" and is constructed from a central drum horizontally supported on bearings. On the drum shaft there is a cam disc (plate) for producing cam functions acting radially from the centre. This machine also has a large mass which is to be rotated, and to handle this situation, in as far as possible, a larger number of processing stations has been put in the generatrix direction.
- the object of the invention is to obviate the aforementioned problems of known packaging machines and to provide a new type of conveyor with its associated processing stations in a packaging machine, which is particularly suitable for the manufacture of packaging cases of the aforementioned type.
- the new concept increases operational reliability and offers great flexibility in its design, and provides conditions for optimal manufacturing and operating costs.
- the object of the invention is achieved by a packaging machine having the basic structure defined in the preamble of claim 1.
- the unique features of the invention are defined in the characterizing part of claim 1, further developments being defined in the dependent claims.

- Fig. 9 shows an arrangement where a camshaft is placed centrally in the conveyor track.
- Fig. 1 schematically shows the principle of construction of a conveyor in one embodiment of the invention.
- a deck 11 is supported on uprights 10, and the outer race 13 of a circular bearing 14 is fixed to this deck by means of a bolted connection 12.
- the bearing 14 is of the type which normally occurs in e.g. wind power plants, digging machines, or armoured vehicles with a rotatable turret and is thus a standard product available at a reasonable cost.
- the circular bearing 14 can have a diameter of the order of 1-1.5 m.
- the inner race 15 of the bearing has a peripheral gear ring 16 and is coupled to the outer race 13 by rolling elements 17.
- a drive motor 18 is also supported in the machine frame, which drive motor can for instance be a servo-motor and which is provided with a gearing arrangement, for example a planetary gearing 19 and a belt transmission 20 on the output shaft from the gearing, which transmission is arranged for driving a shaft 21.
- a gearing arrangement for example a planetary gearing 19 and a belt transmission 20 on the output shaft from the gearing, which transmission is arranged for driving a shaft 21.
- the shaft 21 is supported in bearings at its upper end in the deck 11 and is otherwise supported by the machine frame 10 in a manner not shown.
- a number of case holders 23 are fixed on the inner race 15, which holders support the case blanks 24.
- the case blanks are extracted in a flat state from a magazine (not shown) placed in a supply station along the packaging machine conveyor which is formed by the bearing arrangement 13, 15.
- a number of processing stations are arranged along the conveyor track, for example a station for folding out the bottom end flaps of the cases, a station for sealing a membrane closure on to the folded-out flaps, a station for folding in the bottom flaps, a station for folding out the top flaps of the cases, a station for filling the cases through the open top, a station for sealing a membrane closure on to the top flaps, a station for folding in the top flaps and a station for feeding out filled and ready cases.
- processing stations are spaced out with a predetermined separation along the periphery of the circular conveyor.
- processing tools there are processing tools in the actual stations. Reference is made to these and their drives in a later part of the description.
- Fig.l only shows the principle of the conveyor arrangement, and it is of course implicit that the case holders 23, for example, do not have to be holders which grip around the cases, but they can equally be holders of the carrier finger type, which advance the cases along a sliding path in the circular conveyor track/path.
- Fig. 2 shows an embodiment of an arrangement suitable for said purpose.
- a fixed deck 25 is supported in the machine frame 10, said deck comprising bottom 26, top 27 and side panels 28.
- a bearing 29 being basically of the same type as that in Fig. 1 and provided with a gear ring, is fixed by means of a bolted connection 30 to the bottom 26 of the deck 25.
- a drive motor 31 is coupled via a worm drive 32 to a shaft 33, on which a pinion 34 is mounted in a rotationally-fixed manner for driving the inner race 35 of the bearing 29 by means of its peripheral gear ring 36.
- the shaft 33 is supported by bearings in the deck 25 and in the machine frame (not shown).
- the pinion or the gear ring 37 is in mesh with pinion 38, supported by the top 27 and arranged in suitable positions in the processing stations along the conveyor track.
- the conveyor and respectively the conveyor path for the cases have only been shown schematically in Fig.2 by the chain dotted line 39.
- Fig. 3 shows a further development of the case conveyor of Fig. 1.
- the deck 11 supporting the bearing 14 has been supplemented with a lower deck 40, on which the outer race 13' of a bearing 14", identical to the bearing 14, has been bolted by means of a bolted connection 41.
- the shaft 21 is provided with an additional rotationally- fixed pinion 22' which meshes with the gear ring 16' of the inner race 15'.
- the shaft 21 is made as a splined shaft and a positional adjustment of the deck 40 in the vertical direction is thus possible up to an end position which is shown in dashed lines in the figure.
- a holder arrangement (not shown) is provided on the shaft 21 for fixing the deck in the desired position.
- the circular conveyor is thus formed by two identical bearings coaxially arranged one above the other, where the driven inner race 15 of the bearing 14 supports the upper holder 23 for the cases, and the bearing race 15' supports the lower holder 23'.
- Fig. 4 shows a camshaft arrangement comprising upper and lower decks and intended for the case conveyor shown in Fig. 3.
- the deck 25 in Fig. 4 corresponds to the deck 25 in Fig. 2, and the double bearing races comprising the conveyor arrangement have been indicated by the chain dotted line 39.
- an additional deck 42 is arranged in a vertically displaceable manner as shown by the dashed lines.
- the outer race of a bearing 29' identical to the bearing 29 is fixedly bolted by a bolted arrangement 30' and the inner race 35 of the bearing is driven by a pinion 34' which is rotationally-fixed on to the shaft 33.
- a pinion or gear ring 37' is fixedly bolted to the rotatable inner ring 34', which pinion or gear ring 37' follows the circular rotational movement of the bearing race 35.
- pinions 38' In mesh with this pinion 37' along the periphery of the circular movement path there are additional pinions 38' arranged in suitable positions in the processing stations, which pinions 38' in a manner similar to the pinions 38, are intended to control and/or drive the processing tools.
- Fig. 5 shows a complete arrangement of two conveyor pivotal ring bearings (roller path bearings) and two camshaft pivotal ring bearings, 14, 14' and 29, 29' respectively. From the figure it is clear that the upper camshaft bearing 29 and the upper conveyor bearing 14 have their outer races bolted together by means of bolted connections 43 through the bottom 26 of the deck 25. In a similar way, the lower conveyor bearing 14' is bolted to the outer race of the lower camshaft bearing.
- the pair of inner races in the upper bearing pair 14, 29 is intended for conveyance of, and respectively contribution to processing of, the top of the cases, while the pair of lower conveyor race and camshaft race are intended for the bottom of the cases. Since the lower race pair is adjustable in the vertical direction, a minimum of operations is required for handling cases with differing height formats.
- the driving of the shaft 33 at constant speed is performed by the motor 31 and the gearing 32, and an absolute position sensor 44 (Fig. 4) transmits the current position of the camshaft race to the servomotor 44' which carries out necessary operations, for example intermittent displacement of the case holders 23 in the circular movement path by means of the planetary gearing 44".
- Fig. 6 shows an embodiment where each of the outer races 45, 45' of the camshaft bearings is driven by its own servo-motor 46 and 47 respectively.
- the drive of both the inner races of the conveyor bearings 14, 14' is performed by an additional separate servo-motor 48.
- the directly driven outer race performs the function of transmission to the processing tools with control of the programmable servomotors 46, 47.
- Fig. 6 gives a high degree of freedom and, if desired, the packaging machine can be made to be continuously operating.
- Fig. 7 corresponds to the principle in the embodiment of Fig. 5 with the exception of the drive for the camshaft arrangement and the drive shaft for the conveyor races.
- a revolution-controllable motor 49 is provided which drives shaft 33 via an angle gearing 50 and which drives, via angle gearing 51 and indexing box 52, the conveyor races for intermittent operation synchronised with the control of the camshaft arrangement and/or the drive of the operating tools.
- an indexing box another gearbox can be used e.g. one which allows continuous operation.
- a power take-off device is suitably arranged in the processing stations.
- the pinion 46 is intended to mesh with associated pinions 38 along the circular movement path of the camshaft race and, via an angle drive 47, to drive an output shaft 48.
- this shaft 48 drives processing tools directly or via a transmission mechanism.
- the invention allows a multitude of variations within the framework of the basic concept of a circular element defining the path of movement for a conveyor in a packaging machine.
- the conveyor element is not mounted on bearings in the centre, but at a radial distance from the centre, which in terms of cost gives many possibilities for variations in the detailed design and, not least, gives a machine which is manageable from a service point of view.
- the shown camshaft arrangement can e.g. be replaced with a camshaft placed in the centre of the conveyor track, which has a number of cam discs and curved discs for transmission of movement to the processing tools in the processing stations.
- Such an arrangement is shown in Fig. 9.
- a fixed deck 11 is supported in the machine frame 10 by means of an arrangement of guides 10' and holders 10'".
- the outer race 13 of a pivotal ring bearing 14 is suspended by means of a bolted connection 12.
- the inner race 15 has a plate 23' fixed to it which carries holders 23" for cases 24.
- the inner race 15 is in mesh with a drive pinion 22 on the output shaft of a star coupling 52.
- the star coupling is driven via a shaft 21 from an angle gearing 51 via an additional gearing 50 from a drive motor 49.
- a lower deck 53 is supported in bearings for vertical movement on said guides 10', and a ram arrangement 10" operates against the lower deck 53 and against an upper deck 54.
- the rams are arranged so that, during vertical adjustment, the decks 53, 54 are displaced equal distances from the horizontal plane of the machine defined by the case holders 23".
- a vertical camshaft 33' which is driven from the motor 49 via an angle gearing 50.
- the camshaft 33' is divided by a sleeve 55 applied to the shaft so as to be rotationally fixed thereto, said sleeve 55 allowing vertical displacement of the two shaft parts.
- cam discs 56, 57 Arranged on said shaft parts and fixed against rotation with respect thereto are cam discs 56, 57, movement- transmitting devices (not shown) co-operating with these discs to transmit the necessary movements for the various processing tools in the stations along the conveyor track to the cases on the conveyor race.
- cam discs 56, 57 thus follow the displacement of the decks 53, 54 and thereby take up positions at equal distances from the central plane 23", which allows a simple adjustment of the machine to different case heights.
