- Figure 8 shows a sectional side elevation o an expansion device of the filling device,
- Figure 9 shows a sectional end elevation of the expansion device, and
- Figure 10 shows diagrammatically a modified manner of filling a carton by means of the filling device.
- Referring to the drawings, the
machine 1 for carrying out aseptic packaging includes at one end of the machine aconventional device 2 for pre-forming (including bottom-sealing) gable-topped cartons. The open-topped, pre-formed cartons are taken to the other end of the machine through a closedchannel 3 by means of a chain system. Thechannel 3 is bounded by covers 4 individually liftable about hinges to give access to the channel interior. At this front end of the machine, the open-topped cartons are advanced stepwise and in a vertically upright condition by means of conveyingchains 5 along a hairpin-shaped path P of which an advance leg extends along the machine towards thedevice 2 and a return leg extends along themachine 1 back towards its front end. The cartons exit from thechannel 3 directly into anaseptic chamber 6 1 which totally encloses thechains 5 and which is provided with access covers 6' ' '. Thechains 5, which are arranged coextensively one above another, have projecting therefrom outwardly of the path P long lugs 5' which extend beyond guide strips extending along the path P, the cartons being received among and advanced along the path P by the long lugs 5' and being supported at one side by thechains 5 and at the other side by the guide strips. Thechains 5 carry the cartons first of all to a top pre-breaking , device 7, where the open top of each carton is pre- broken. Then the cartons are passed beneath high-intensity ultra-violetgermicidal lamps 8 which extend over a section of the hairpin-shaped path P which forms at least a major portion, in the present case in fact.a major portion, of the length of the advance leg of the path P. In the region of the beginning of this section of the path P, there is arranged some means for introducing into the interior of the carton a fine spray of hydrogen peroxide (H202). This means comprises a nozzle arrangement 7' incorporated in the pre-breaker 7 and serving to spray particularly the inside of the carton with H202. The combined effect on the interiors of the cartons of the ultraviolet radiation and the hydrogen peroxide has a synergistic sterilizing action which is highly germicidal. Where the degree of sterilisation required is not very great, it is possible to omit use of hydrogen peroxide. At the downstream end of this path section, thechains 5 carry the cartons round through 180° to start the return leg of the path P. On this leg, the cartons first arrive at afilling device 9 where the cartons are filled with an aseptic product, for example long-life milk, the cartons then proceeding to a top heating device 10 where thermoplastics surfaces of the top of each carton are heated to a tacky condition, and the cartons are then advanced to atop sealing device 11 where the gable tops are sealed. The cartons leave ' theaseptic chamber 6 at anexit hole 6" therefrom at the front end of the machine. Throughout the operation of the machine, aseptic air is fed from a main sterile air filter toaseptic air inlets 13 and 13' of thechamber 6, in which chamber the aseptic air flows from theinlet 13 relatively smoothly to the front end of thechamber 6, where the aseptic air leaves via anaseptic air outlet 14. Not only does the aseptic air act as a scavenging gas removing microbes and hydrogen peroxide from thechamber 6, particularly tending to prevent the microbes and the hydrogen peroxide from being carried up to thefilling device 9, but the aseptic air also maintains the interior of thechamber 6 at a pressure slightly above atmospheric and thus discourages the entry of ambient air into the chamber. - Referring particularly to Figures 4 and 5, the top pre-breaker 7 is in two
sections untal support 73 itself carried by twohorizontal arms 74 fixed to a verticallyreciprocating plunger 75. Thesection 71 comprises two substantiallytriangular flaps 76 turnable about respective substantially horizontal parallel pivots 77 by respectiveoscillatory cranks 78. Between each two advances of the stepwise-advanced cartons, the pre-breaking device 7 is lowered onto the two cartons beneath it, and performs its pre-breaking and simultaneously the H202 is sprayed into the carton immediately beyond thesection 72 by the nozzle device 7'. - The
filling device 9 is particularly designed to prevent microbes obtaining access to the aseptic liquid product being supplied to thechamber 6. Referring to Figures 6 to 9, the filling device includes amounting frame 20 which mounts four stainless steelreciprocatory bellows 21 having bottom walls which are reci- procatorily driven byrespective reciprocatory plungers 22 and having top flanges fixed to respective lower limbs of T-unions 23. Respective upper limbs of theunions 23 contain respective spring-loaded, non-return, inlet valves which open to allow downward flow through the limbs. Intermediate limbs of therespective unions 23 are connected to respectivearcuate pipes 24 which curve downwardly and which at their lower ends are connected torespective outlet nozzles 25 which contain respective spring-loaded, non-return, outlet valves. Thechains 5 advance the cartons stepwise directly below the line ofnozzles 25 and a selected number of thebellows 21 are operated each to deliver a predetermined a dosage of long-life milk to the vertically upright cartons, the number ofbellows 21 operated being dependent upon the nominal capacity of the cartons. Thus, with eachbellows 21 being pre-set to deliver a halfpint at each reciprocation, all fourbellows 21 are operated for cartons which can each hold one quart. On eachbellows 21 performing a pressure stroke, because the inlet valve in itsunion 23 is held closed by its spring and by the milk pressure, the inlet valve is automatically opened against the action of its spring so that thebellovs 21 can draw in milk from anexpansion device 26 shoun in Figures 8 and 9. Thedevice 26 is connected to the upper limbs of all of the T-unions 23 by way of itsoutlet 27. A pump (not shown) continuously pumps long-life milk into thedevice 26 through itsinlet 28. The interior of thedevice 26 is divided into anexpansion chamber 29 and a constant-pressure chamber 30 by anannular bellows 31 and a rigid, movable,end closure wall 32 thereof. Thechamber 30 is set at a substantially constant pressure owing to the provision of a pressure-regulated air supply to thechamber 30 via aport 33 in aremovable end wall 34 of thedevice 26. There extends through thewall 34 in a fluid-tight manner arod 35 which is fixed at one end to the plate'32. Therod 35 carriesabutment flanges 36 which limit the degree of movement of thewall 32 relative to thewall 34. Therod 35 also carries apointer 37 which moves over ascale 38 to indicate the position of thewall 32 in thedevice 26. In use of the machine, when the instantaneous rate of delivery of the pump to theinlet 28 exceeds the rate of drawing of the milk into thebellows 21 via theoutlet 27, thewall 32 is moved by the pressure of the milk to the right in Figure 9 against the action of the air pressure in thechamber 30, so that theexpansion device 26 acts temporarily as a reservoir until the rate of drawing of the milk into thebellows 21 exceeds the rate of delivery by the pump, in which case theplate 32 moves to the left in Figure 9 under-the action of the air pressure in thechamber 30. It will thus be appreciated that, at least between the pump (not shown) and the outlet valves in thenozzles 25, the filling system is always absolutely full of long-life milk, so that there are no voids or air spaces, which would possibly allow microbes to obtain access to the milk. Another advantage of the present filling system is that all of the internal surface area of the system which in use is in contact with the long-life milk can itself easily be sterilised by simply passing a very hot liquid, chemical cleaning fluid or steam through the filling system, so that all of that internal surface area comes into contact with the very hot liquid, the fluid, or the steam. - Referring to Figure 10, a carton C is shown being filled from one of the
nozzles 25. It will be noted that, in this modified manner of filling, the carton C is in a position inclined to the vertical, so that the milk flowing from thenozzle 25 falls down onto an internal face of. the carton C which face is inclined to the vertical and is directly below thenozzle 25. Compared to a conventional arrangement in which a nozzle pours milk down into a carton arranged in a substantially exactly upright position directly below the nozzle and thus the milk leaving the nozzle virtually always pours directly onto a body of milk in the carton, the arrangement shown in Figure 10 has the advantage of minimising the production of foam on the top of the milk. In the present case, the cartons C move along the path P in upright positions, except in the region of thefilling device 9, where they are in a tilted condition. It will be appreciated that movement of the carton from its upright condition to its tilted condition and then back to its upright condition can be produced in various ways, particularly by suitable design of thechains 5 and/or the guide strips for the cartons. - The
machine 1 also includes automatically controlled means for cleaning the internal surface of theaseptic chamber 6, this means consisting ofspray nozzles 41 distributed centrally along the length of the chamber. These nozzles serve to supply a cleaning fluid, e.g. a hot detergent solution or steam, to the interior of thechamber 6 in such a manner that the whole of the interior of thechamber 6 receives the cleaning fluid, which can then be drained off through a drain (not shown). - The
machine 1, particularly theaseptic chamber 6 and the associated machine parts, such as theitems 5 to 11, are so designed that the only non-aseptic matter deliberately introduced into thechamber 6 is the preformed cartons C. - The entry 3' where the empty cartons enter
theaseptic chamber 6 and the exit 6' ' where the filled cartons leave the aseptic chamber can be sealed off outside thechamber 6 by respective air curtains of aseptic air at higher-pressure. Thus the lower-pressure aseptic air inside thechamber 6 is prevented from escaping. These air curtains are established by slottedtubes chamber 6 itself.
