    Device for manufacturing articles from biodegradable materials and method in which such device is used.
    The present invention relates to a device for manufacturing articles from biodegradable materials and to a method in which such a device is used.
    More specifically, the invention is intended for the manufacture of articles from agricultural products such as potato starch, corn, cassava, rice peels and the like that are biodegradable.
    It is known that biodegradable products are recyclable by nature and can replace synthetic plastics that give rise to an ever-increasing pile of waste from toxic and non-biodegradable products, often from plastic packaging.
    The plastic waste problem affects all countries in the world, but especially in the economically fast developing countries, the environment is threatened by this problem, making the waste problem the subject of several international conferences.
    Thus it is possible to produce utensils such as noodle cups, or lunch boxes from biodegradable materials. The daily consumption for each of these items in China alone is around 200 million units per day!
    A major advantage of biodegradable materials, such as starch, for example, is that the articles made from it can be recycled after use, either as cheap natural energy or as fertilizer in agriculture. These biodegradable materials are 100% degradable and dissolve in the soil within 20 days.
    Starch is a suitable material for the manufacture of food packaging such as hamburger boxes, cheese or meat dishes, fruit baskets and other dry food carriers.
    Rice peels are mainly used for products with a high water content and for food dishes such as those used for airplane meals.
    In addition to food packaging, the biodegradable materials are not only suitable for packaging smaller volumes, but also for higher-quality products such as electronic consumables.
    Biodegradable materials have since been developed to a point where mass production is possible for the consumer market.
    Traditionally, solid products such as starch are processed into a dough, from which objects can be pressed into a mold.
    But also more liquid products such as defragmented lactic acid or citric acid mixed with glycerol, enzymes and other plant materials can be processed for the production of objects. In this case the liquid is pumped with a controlled pressure with which the mold is filled.
    Often objects are made from synthetic polymers by extruding molten polymer into the desired shape or die, after which the shaped item is taken out of the die after cooling.
    This extrusion technique cannot be applied to biodegradable polymers, because they are not suitable for being melted and therefore must first be pressed or cast into a mold before heating or baking in the mold to give them their final shape.
    A problem arises when large quantities of articles have to be made from a biodegradable material. The use of a single mold, as is usual in extrusion technology, limits the speed with which a large number of objects, for example packages, can be manufactured.
    An additional problem arises when sets of different objects such as different packaging forms have to be manufactured and the mold has to be replaced by different ones. The machine must be shut down and converted, which, especially for small series of a certain package, has a very adverse effect on the cost price per package and makes the automation of the production more difficult.
    The present invention has for its object to provide a solution to the aforementioned and other disadvantages in that it provides a device for the manufacture of articles from biodegradable materials which makes it possible to simultaneously manufacture several articles of the same or of different shape from solid or liquid biodegradable materials by means of filling and heating molds in which each mold not only has an individualizable shape, but also runs through a computer-controlled individualizable process program and can be individually disconnected, without having to shut down the device.
    To this end, the invention relates to a device for manufacturing articles from biodegradable materials consisting of a storage tank with solid or liquid biodegradable material that is coupled to a distribution line along which a series of molds with an individualizable shape are filled and wherein each mold has an individualizable computer-controlled process program that determines the filling time, the pressure and the temperature and afterwards automatically opens the mold and removes the molded object, after which a subsequent copy can be pressed or cast in the same mold.
    An advantage of such a device is that several types of objects can be manufactured simultaneously on one machine in an automated manner, so that one operator can have several mold forms produced simultaneously.
    Preferably, each mold can be disconnected individually, whereby the operation of the entire device does not have to be stopped, and the remaining molds continue to produce, while one mold is replaced by a different one.
    An advantage of this detachability is that a certain mold shape can be used for a specific type of packaging, for example that has to be manufactured in a smaller series, after which this mold shape can be replaced by a different one for another, and without the production in to interrupt the other molds, so that production is possible continuously for 24 hours a day, 7 days a week.
    Preferably, each mold is automatically controlled by a computer-controlled individual process program, which opens the supply line from the distribution line, fills the mold, traverses a heating strip in the mold until the desired shape is baked in, opens the die, loosening the molded article, closing the die and automatically repeating these steps to produce a subsequent one, and this until the desired sequence has been completed.
    An advantage of such a computer-controlled process program is that the whole series of objects to be produced can be produced without manual assistance and without being interrupted by starting or stopping other series in the other molds connected to the distribution line.
    The mold is preferably opened by means of a computer-controlled electrically driven hydraulic piston which is connected via a pivot point with an eccentric point on a plate-shaped lever and which in a first phase covers the lid of the mold which, when closed, moves into a vertical position. position, opens by moving this lid horizontally over a small distance (10 mm), after which the lid is folded upwards by 90 ° using the plate-shaped lever that is hinged to the lid, until the lid is in a horizontal position .
    The molded article in the biodegradable material can now be detached from the mold and removed automatically.
    The invention also relates to a method for producing articles from a biodegradable material which comprises the following steps: - Collecting biodegradable raw materials or biological waste products from agriculture; - forming a dough or liquid from the biodegradable raw materials by mixing in water and biodegradable additives; - transporting the pourable or compressible mixture to a storage tank of a device for manufacturing articles from biodegradable raw materials as described in claim 1; - connecting suitable molds to a distribution line of a device as described in claim 1; - going through a production cycle as described in claim 3, wherein for each individual mold a computer-controlled individual process program is run adapted to the object to be manufactured; - the collection and packaging of the manufactured articles per type and per series size for dispatch to consumers.
    The biodegradable additives that are added to the degradable raw material are selected in function of the properties to be achieved in the manufactured articles. For example, vegetable resins can be used as binders or natural emulsifiers, while remaining fully biodegradable.
    With the insight to better demonstrate the characteristics of the invention, a preferred embodiment of a device for manufacturing objects from a biodegradable material according to the invention is described below, with reference to the accompanying drawings, as an example without any limiting character. , wherein: figure 1 schematically and in perspective represents a device for manufacturing objects from biodegradable materials according to the invention; Figure 2 represents a side view of Figure 1; figure 3 represents a top view of figure 1; figure 4 represents the plan view of one mold, indicated by F4 in figure 3, on a larger scale and in more detail; figure 5 represents a section along line V-V in figure 4; figure 6 represents in perspective some objects made of biodegradable material manufactured with the device shown in figure 1.
    Figure 1 shows a device for manufacturing objects from biodegradable materials 1 according to the invention, consisting of a supporting framework 2 with a platform 3 provided with a handrail 4, on which a storage tank 5 is placed for storing biodegradable material which is connected to a dividing line 6 which is lockably coupled to each of the in this case twelve molds 7, each provided with a cover 8 and each connected to a computer 9 with a touch screen from which the operation of the device can be controlled.
    Figure 2 shows a side view of Figure 1, perpendicular to the longitudinal direction of the distribution line 6, to which the twelve molds 7 are coupled. The lid 8 'of some molds is in the horizontal open position, while other molds are closed with the lid 8 in the vertical position.
    Figure 3 shows a top view of the device of Figure 1, on which it can be seen which molds 7 have been opened with their lid 8 'folded out to the horizontal position, while the others show their lid 8 in closed and vertical condition.
    Figure 4 shows in more detail the top view of one mold 7, the lid 8 of which is in the vertical closed state. Above the mold 7 there is an electrical housing 10, which is connected to a computer 9 via a cable 11 with USB connection 12 on the one hand, and on the other hand is connected via a flexible electrical cable 13 to the lid 8 of the mold 7. A plate-shaped lever 14 connects the horizontal axes 14a and 14b.
    Figure 5 shows a cross-section of Figure 4 on which the mechanism can be seen with which the lid 8 of the mold 7 can be brought into the open position 8 '. In the electrical housing 10 there is a computer-controlled electrically driven hydraulic piston 10 ', which is connected via pivot point 14c to an eccentric point on a plate-shaped lever 14 which is itself hinged in the electrical housing 10 on the one hand around shaft 14a and on the other hand around shaft 14b in the upper side of the lid 8 of the mold in the closed vertical position or of the lid 8 'in the open horizontal position. The mold 7 is attached to a head plate 15 in which four openings for supporting screws are provided as well as four openings for the supply of biodegradable material to the mold 7.
    Figure 6 shows in perspective some objects that were manufactured by means of the device represented in Figure 1. A lunch box 16 and a dish for noodles 17 are shown, as well as a dish for foods 18, all of which are made from starch.
    The operation of the device 1 for manufacturing articles from biodegradable materials according to the invention can be described as follows.
    The storage tank 5 of the device 1 is filled with a dough of biodegradable material such as vegetable starch or with a liquid form of a biodegradable material such as lactic acid or citric acid mixed with glycerol, enzymes and other plant materials.
    The biodegradable material is pressed or pumped in a continuous process into a mold 7, where it acquires the desired shape and is then heated to the desired temperature at which the article 17 is baked in a given time, giving it its final shape.
    The continuous process is controlled by a driver in a computer 9 that can be operated by means of a touch screen. The touch screen shows all molds 7 that are connected to the storage tank 5 via one distribution line 6.
    The computer 9 sends six basic commands to each mold 7 separately at the appropriate time: 1) opening the supply tap to the mold; 2) filling the mold 7 with dough or solution; 3) closing the supply tap to the mold; 4) controlling the baking time and the temperature in the mold 7 according to the object produced; 5) opening the mold 7 by folding open the lid 8 and removing the manufactured object 17 from the mold 7 for collection in a receptacle; 6) closing the mold 7 again by closing the lid 8 and restarting the production cycle for a subsequent one.
    Opening of the mold 7 by folding open the lid 8 is electronically controlled by the computer 9 by the movement of an electrically driven hydraulic piston 10 'which is connected via pivot point 14c to an eccentric point on a plate-shaped lever 14 which is itself hinged is in the electrical housing 10 around shaft 14a on the one hand and in the upper side of the cover 8 of the mold around shaft 14b on the other hand. In a first phase, the piston 10 'pushes against the pivot point 14c, the cover 8 of the mold 7 being moved over a small distance (10 mm) in the horizontal direction so that the cover 8 comes away from the mold 7 in which the object is formed. In a second phase, the piston 10 'pivots the plate-shaped lever 14 upwards through 90 °, the lid 8' now being in a horizontal position, and the manufactured object is pulled out of the mold 7 via an eye-shaped hook (not shown) on each side of the mold 7 after which the manufactured article 17 is guided to the desired conveyor belt.
    The closing of the mold 7 is controlled by the computer 9 by going through the above movements in reverse order, after which the cycle is repeated for a subsequent copy until the desired number of objects is produced. The duration of the production cycle of one item can vary from 15 seconds to 45 seconds depending on its size. The molds 7 and covers 8 are made of cast aluminum and have an anodized non-stick coating on the contact surface of the object to be produced. The mold 7 consists of a female part fixedly attached to the head plate 15, and a male part forming part of the movable lid 8. The weight of a mold varies from 10 to 16 kg depending on the object to be formed. Both the female part and the male part of the mold 7 are provided with an electric heating coil, which is controlled by the process program in the computer 9 and wherein each mold separately goes through a programmed temperature trace that is individually adjustable per mold 7.
    The computer 9 also controls the press or pump that supplies the distribution line 6. The operator can increase the pressure in the distribution line depending on the number of molds 7 in use. The speed of the feed flow can be regulated according to the weight of the objects to be manufactured per unit of time. The driver can control up to 30 molds in one distribution line of a device at a time. Multiple devices can be arranged in parallel with each other, so that a production line with high capacity can be formed.
    It goes without saying that the distribution line 6 of a device can be arranged not only horizontally, but also vertically or in other orientations depending on the circumstances.
    The present invention is by no means limited to the embodiment described by way of example and shown in the figures, but a device for manufacturing articles from biodegradable materials according to the invention can be realized in all shapes and sizes without departing from the scope of the invention .
