Abstract

A new automatic process is proposed for manufacturing, filling and evacuating large containers of (square) block-bottom type up to a capacity of 100 liters, particularly for milk powder. In addition, an automatic packaging and evacuating machine is proposed for manufacturing such evacuated block-bottom bags. The process is preferably effected while using a thermally processable laminated foil with excellent resistance to high mechanical stress, steam, gas and light permeability, in evacuating chambers operating simultaneously, though preferably discontinuously, with an appropriate vacuum capacity. Now it is possible, e.g., to load and position three block-bottom bags of each 100 liters per each cycle in the vacated empty evacuating chamber (14, 14'), while interposing a reciprocating charging device moving preferably at right angles to the direction of motion of the filled block-bottom bags. After closing the chamber, the evacuating is carried out until the desired minimum end pressure is obtained. Thereafter inert gas or a gas mixture may be introduced to reduce the minimum end pressure and during this operation the opposite chamber is unloaded and loaded respectively. Synchronical control takes care of constant alternating yet continuous presence of a number of block-bottom bags in either evacuating chamber until the predetermined rate of vacuum has been reached. Vacuum sealing is then finally effected within the evacuating chamber and following decompression of the evacuating chamber. The set of preshaped block-bottom bags is transported off upon a second conveyor. In view to the space requirements it is also preferable to position and displace the off transport device in a reciprocating manner perpendicular to the direction of the movement of the bags.

Description

The invention relates to an automatic method for producing, filling and evacuating large packaging in block-bottom containers up to 100 liters, especially for instant products and other powdery products or other hygroscopic foods such as milk powder.
The invention also relates to a packaging and evacuation machine for using the method.
The automatic process for the production, filling and evacuation of large packagings in block bottom containers up to 100 Ltr.content, especially for instant products and other powdery products or other hygroscopic foodstuffs such as milk powder, is new and cannot be used with known processes such as for vacuum-packed coffee Compare small packaging. A comparison with individual evacuation chambers is also not applicable due to their manual operation and the manual loading and emptying.
Rather, the method according to the invention intends to produce large packaging, which was previously not customary, continuously and automatically with a large output and therefore economically, for transport and storage at the lowest cost, for quickly perishable foods or foods which react to normal atmospheric influences. The packaging used so far, consisting of kraft paper / PE, protects products such as whole milk powder only to a limited extent. When transporting to so-called Third World countries due to climate influences, improper storage during and after transport, as well as insect infestation and the rapid oxidation of the product, which lead to spoilage, one point is that container or storage capacity that is not optimally utilized is another. As a result, considerable values are lost. It was therefore necessary to develop a process that allows large containers to be produced automatically and continuously using a composite film, economically and with a high output, even though this involved major difficulties. Food, such as whole milk powder, is an indispensable primary food for third world countries, which is currently exported in cylindrical cans due to the lack of alternatives. Enormous price increases in packaging and packaging goods, such as whole milk powder, make the product unaffordable for the masses in third world countries.
After extensive tests, it was found that with the new method according to the invention, and using a very suitable composite film, it is entirely possible and contrary to the opinion of experts that large quantities of inexpensive large packaging, for example for 25 kg of whole milk powder, are possible. to produce, which can replace the previous usual kraft paper / PE sack with its known disadvantages.
With the method according to the invention, it is now possible to economically fill and evacuate stackable block-bottom packaging of up to 100 liters or, for example, 25 kg of whole milk powder in large quantities, a fact that was previously considered absolutely impossible by relevant experts.

The new automatic process for manufacturing, filling and evacuating is characterized by the fact that under its application large packaging is produced in block-bottom containers up to 100 liters, especially for instant products and other powdery products or other hygroscopic foods such as Milk powder, using a thermoplastic composite film with excellent resistance to high mechanical stress, water vapor, gas and light permeability, but at the same time, however, preferably discontinuously operating evacuation chambers with a corresponding vacuum capacity, e.g. three 100 liter block bottom sacks per cycle, with a plug-in device that can be moved back and forth, preferably transversely to the direction of travel of the filled block bottom sacks, in order to insert and position the block bottom sacks into the currently free evacuation chamber; after the chamber has been closed, a vacuum is applied to it to reach the freely selectable final pressure, which can be reduced again after reaching it by adding an inert gas or a gas mixture, to the desired final pressure, during which the other chamber is emptied or filled, synchronized in such a way that always alternately but continuously, a set of block bottom bags remains in an evacuation chamber until it has reached the preselected vacuum values in order to be finally sealed inside the evacuation chamber, under vacuum, and after the decompression phase of the evacuation chamber as a solid block bottom bridge to be intermittently transported on a second transport device to the outside, preferably so that the retractable each is requested by the just waiting for extending evacuation chamber and therefore can be also preferably transversely to the outlet direction traverse back and forth.

To use the new process, a packaging and evacuation machine is provided for the production of vacuum packaging for perishable foods under normal atmosphere such as whole milk powder, preferably in block bottom packaging up to 100 liters, using the Method of the aforementioned method, which is characterized in that the machine forms at least one integral unit and comprises the following processing stations:

• a] automatic and continuous product supply;
• b] an automatic high-performance metering device;
• c] a block bottom forming, filling and sealing machine working vertically and from the roll, whereby the molding and filling tube is worked in such a way that a clean edge shaping is achieved, the product can be regulated at falling speed and a stable bottom can be inserted, sealing tools worked in this way are that a partial seal is achieved at the top seam, but a continuous seal including the bottom is achieved at the bottom seam and is folded over by means of a chilled beam;
• d] a plurality of automatically operating, infinitely variable transport units for the transport and pre-sorting of the block bottom packaging between the filling machine and the evacuation chambers;
• e] an automatic evacuation unit, consisting of one or more evacuation chambers, preferably adapted to the output of the packaging machine, but with a considerable vacuum capacity, preferably from a performance combination of 400/1000 m3 / h, for the simultaneous evacuation of up to several large block bottom containers with dimensions of e.g. 600 x 340 x 240 mm per unit.

In a preferred embodiment of the packaging and evacuation machine, an automatic and continuously working product feed is provided, which feeds a high-performance dosing device with a large capacity, preferably a net bulk weigher, which in turn is a, preferably vertically working, sack form, fill and seal machine with the requested product quantity supplied. An integrated transfer station transfers the partially closed block bottom bag to the downstream transport unit, which handles the transport and formatting of the block bottom bags. After reaching the formation, for example 3 block bottom containers of 25 kg whole milk powder each, the infeed conveyor of the evacuation stations is requested and the packaging is handed over. The transfer to the infeed conveyor is registered and the further transport to a free evacuation chamber is initiated. Reaching the open evacuation chamber, flush with the conveyor belt installed in it, starts the transfer inlet. The block bottom packaging now located in the evacuation chamber is again registered and the opened chamber half is closed. During the closing process, the packages are arranged on the side of the conveyor belt Sheets pressed on, the signal chamber to control the vacuum pump unit and the evacuation process begins, at the same time activating the film pressing device which secures the container against movement. As soon as the preselected negative pressure is reached, the minus pressure is compensated with an inert gas or a gas mixture. The negative pressure is compensated to a freely selectable final value between 0.0 and 760 Torr. The signal then given releases the sealing function. The thermostatically controlled sealing tools run in parallel are closed hydraulically with a definable pressure in order to carry out a continuous sealing underneath the already existing partial sealing. A separating knife integrated above the sealing surface and matched to the packaging material cuts off the protruding flag.
The sealing process initiates the remaining decompression of the evacuation chamber. As soon as the pressure equalization has taken place and is registered, the evacuation chamber opens and requests the discharge belt. Reaching the discharge belt flush with the conveyor belt permanently installed in the evacuation chamber enables the containers which have now become fixed by the atmospheric pressure to be removed. As soon as the transfer to the laterally movable conveyor belt has been registered, the side transport is initiated up to the center and flush with a further conveyor belt in the direction of palletizing.

Die Anlage 1, Fig. 1, womit das erfindungsgemässe Verfahren durchgeführt wird, ist zusammengesetzt aus zwei Verarbeitungsstationen, d.h. durch eine Abfüllstation 2 und durch den Evakuierungsautomaten 3. Auf der Abfüllstation 2 wird eine Verbundfolie von der Rolle zu einem am Boden geschlossenen Schlauch versiegelt. Während des Siegelns wird der Blockboden eingelegt. Ist das Gebinde fertig geformt, wird es über die Dosiereinrichtung 4 mit Produkt, z.B. 25 Kg Milchpulver, gefüllt. Nach dem Abfüllvorgang wird das Blockboden­gebinde 5, hier schematisch dargestellt, auf die Übergabestation 6 abgesenkt. Diese Übergabestation 6 schiebt das Blockbodengebinde 5 mittels einer hydraulisch betätigten Halbkasette 7 auf das erste Transportband 8 das den Transport bis zum zweiten Transportband 9 übernimmt.
Nach Erreichen des zweiten Transportbandes 9 taktet dieses das Blockboden­gebinde 5 exakt um eine Gebindebreite zuzüglich des gewünschten Abstandes zwischen den einzelnen Blockbodengebinde, weiter. Ist die Anzahl der vor­gewählten Gebindemenge auf dem zweiten Transportband 9 durch Sortieren erreicht, werden die Gebinde auf das Zufuhrband 10 des Evakuierungsautomaten 3 übergeben das sich dabei in seiner Grundstellung in der Fig. 2 befindet. Das Zufuhrband 10 ist, wie die Fig. 4 zeigt, auf einem Rahmen 11 seitlich verfahrbahr gelagert über ein Paar Gleitschienen 12 und der Antrieb wird übernommen von einem hydraulischen Zylinder 13 der sich unterhalb des Zufuhrbandes 10 befindet und üblicherweise einerseits fest mit dem Rahmen 11 und andererseits beweglich mit dem verfahrbaren Zufuhrband 10 verbunden ist. Weitere Konstruktionsdetails sind einfachshalber weggelassen. Sobald die Kammer 14 öffnet fordert sie damit gleichzeitig das Zufuhrband 10 an und dieses verfahrt mit den darauf sortierten Blockbodengebinde 5, z.B. drei Stück, in Richtung der offenen Kammer 14. In der Kammer 14 ist ein Kammertransportband 15 angeordnet. Nach Erreichen der bündigen Endposition, Fig. 6, setzt der Transport vom Zufuhrband 10 und Kammertransportband 15 in gleicher Laufrichtung ein. Nach erfolgter Positionie­rung innerhalb der Kammer 14 wird dieser Transport gestopt, die Kammer 14 schliesst sich, Fig. 5, und das Zufuhrband 10 verfährt danach wieder in seine Grundstellung. Das Signal "Kammer zu" schaltet die Pumpeneinheiten 16 auf Betrieb und der Vakuiervorgang beginnt. Während des Evakuierens werden die Gebinde 5 über Andruckrollen 17 in Position gehalten und geformt. Nach Erreichen des vorgewählten Minusdruckes wird entweder Rückbegast über Wechselventile 18 mit einem inerten Gas oder Gasmischung, bis zum gewünschten Minusenddruck. Der erreichte Enddruck gibt das Signal an die Siegeleinheit 19 und die End­verschweissung der drei Gebinden 5 werden gleichzeitig vorgenommen. Die erfolgte Endverschweissung leitet die entgültige Dekompression über Ausgleichs ventile 20 ein während die Andruckrolle 17 die noch hochstehende Restfahne der Verpackungsfolie umlegt. Nach Erreichen von NN fordert Kammer 14 das Abtransportband 21 an bei gleichzeitigem Öffnungsvorgang. Sobald die Kammer 14 geöffnet ist setzen sich das Kammertransportband 15 und das Abtransportband 21 synchron in Betrieb. Abtransportband 21 übernimmt die drei Gebinde 5. Die erfolgte Übernahme signalisiert den Seitenverschub in Richtung Grundstellung, Fig. 8. Sobald diese Grundstellung erreicht ist setzt der Transport und damit die Übergabe auf den Palettiereinlauf 22 ein. Der Zyklus von Kammer 14 ist beendet. Danach findet diskontinuierlich einen identischen zweiten Zyklus statt aber dann für die Zufuhr der nächsten sortierten Gebinde 5 in die zweite Kammer 14′ an der gegenüberliegenden Seite des Zentralgehäuses 23. Eine weitere Beschreibung davon wird einfachshalber nicht gegeben.
In den Fig. 4 und 9-12 ist noch gezeigt wie die Blockbodengebinde 5 sowohl ausserhalb als innerhalb der Kammer 14 zwischen je zwei aufstehenden Seiten­wanden 24 die sich seitlich des Transportbandes 27 befinden, positioniert werden.
Eine zentrale Prozessoreinheit 28 ist vorgesehen welche genau alle aufeinander­folgenden vorerwähnten Verfahrensschritte der Anlage 1 regelt. Weitere Einzelheiten der Anlage 1 ergeben sich noch aus der Zeichnung, Fig. 1 und 14. Die Verbundfolierolle 29 ist an der Unterseite des Rahmens 30 der Abfüll­station 2 untergebracht und die Verbundfolie wird hochgeführt bis sie etwa in der Nähe unterhalb des Milchpulverdosiergefässes 31 bis zu einem Schlauchfolie umgeformt wird. Das Dosiergefäss 31 wird gefuttert von dem grösseren Milch­pulverbunker 32 unter Zwischenschaltung von einer Zufuhr 33. Das Öffnen und Schliessen der Kammern 14 und 14′ findet statt durch einen ähnlichen Antrieb mit zwei hydraulischen Zylinder 34. Jede Kammerhälfte die sich öffnen kann ist mit dem beweglichen Zylinderteil verbunden, der feste Zylinderteil ist mit dem Rahmen 11 verbunden. In den Figuren ist weiter noch gezeigt dass die Seitenwanden 24 z.B. bei 35 ajustierbar sind damit Blockbodengebinde mit verschiedenen Dimensionen von der Anlage 1 hergestellt werden können.Further advantages are given below on the basis of the description of an exemplary embodiment of a packaging and evacuation machine.

The system 1 , FIG. 1 , with which the method according to the invention is carried out, is composed of two processing stations, that is to say by a filling station 2 and by the automatic evacuation device 3 . At the filling station 2 , a composite film is sealed from the roll to form a tube closed at the bottom. The block bottom is inserted during the sealing process. Once the container has been shaped, it is filled with product, for example 25 kg milk powder, via the metering device 4 . After the filling process, the block bottom container 5 , shown schematically here, is lowered onto the transfer station 6 . This transfer station 6 pushes the block bottom container 5 onto the first conveyor belt 8 by means of a hydraulically operated half-cassette 7 , which takes over the transport to the second conveyor belt 9 .
After reaching the second conveyor belt 9, this clocks the block bottom container 5 exactly by a container width plus the desired distance between the individual block bottom containers. Is the number of preselected containers amount on the second conveyor belt 9 achieved by sorting, the containers are on the infeed conveyor belt 10 to pass the evacuation machine 3 the case is in its initial position in FIG. 2. The feed belt 10 is, as shown in FIG. 4, mounted laterally movable on a frame 11 via a pair of slide rails 12 and the drive is taken over by a hydraulic cylinder 13 which is located below the feed belt 10 and is usually fixed on the one hand to the frame 11 and on the other hand, is movably connected to the movable feed belt 10 . Further construction details are omitted for the sake of simplicity. As soon as the chamber 14 opens, it requests the feed belt 10 at the same time and this moves with the block bottom containers 5 sorted thereon, for example three pieces, in the direction of the open chamber 14 . A chamber conveyor belt 15 is arranged in the chamber 14 . After reaching the flush end position, Fig. 6, the transport from the feed belt 10 and chamber conveyor belt 15 begins in the same direction. After positioning within the chamber 14 , this transport is stopped, the chamber 14 closes, FIG. 5, and the feed belt 10 then moves back into its basic position. The "chamber closed" signal switches the pump units 16 to operation and the vacuuming process begins. During the evacuation the Container 5 held in position by pressure rollers 17 and shaped. After the preselected negative pressure has been reached, either return gas is supplied via shuttle valves 18 with an inert gas or gas mixture until the desired negative final pressure is reached. The final pressure reached gives the signal to the sealing unit 19 and the final welding of the three containers 5 is carried out simultaneously. The final welding is carried out, the final decompression via compensating valves 20 while the pressure roller 17 folds over the remaining lug of the packaging film. After reaching NN, chamber 14 requests the removal belt 21 while opening at the same time. As soon as the chamber 14 is opened, the chamber conveyor belt 15 and the conveyor belt 21 start up synchronously. The conveyor belt 21 takes over the three containers 5 . The successful transfer signals the lateral shift in the direction of the basic position, FIG. 8. As soon as this basic position has been reached, the transport and thus the transfer to the palletizing inlet 22 begin. The cycle of chamber 14 has ended. Thereafter, an identical second cycle takes place discontinuously, but then for the supply of the next sorted container 5 into the second chamber 14 'on the opposite side of the central housing 23. A further description of this is not given for the sake of simplicity.
4 and 9-12 it is also shown how the block bottom containers 5 are positioned both outside and inside the chamber 14 between two upstanding side walls 24 which are located on the side of the conveyor belt 27 .
A central processor unit 28 is provided which controls exactly all successive aforementioned method steps of the system 1 . Further details of the system 1 can be seen from the drawing, FIGS. 1 and 14. The composite film roll 29 is accommodated on the underside of the frame 30 of the filling station 2 and the composite film is brought up until it is approximately in the vicinity below the milk powder metering vessel 31 Tubular film is formed. The metering vessel 31 is fed by the larger milk powder hopper 32 with the interposition of a feed 33 . The opening and closing of the chambers 14 and 14 'takes place by a similar drive with two hydraulic cylinders 34th Each chamber half that can open is connected to the movable cylinder part, the fixed cylinder part is connected to the frame 11 . In the figures, it is also shown that the side walls 24 can be adjusted, for example at 35 , so that block bottom containers with different dimensions can be produced by the system 1.
