Definitions

  • the invention relates to a method for producing a storage container for liquids, in particular heating oil, made of thermoplastic, whereby at least two elementary containers are molded simultaneously in a blow mold or a rotary mold and the elementary containers are connected to one another by at least one lower and one upper connecting channel, wherein the elementary containers and the connecting channels are simultaneously formed as an integral part.
  • Plastic storage tanks for heating oil or any other liquid goods are manufactured with different capacities.
  • a container battery also known as a battery tank.
  • the larger the capacity of a container the greater the wall thickness of the container must be.
  • the elementary containers can have much smaller wall thicknesses than containers with large walls.
  • the elementary containers are cylindrical, arranged in a row and connected to one another via connecting channels.
  • the connecting channels lie in a longitudinal median plane of the container.
  • Distances are provided between the elementary containers, which cannot be avoided because of the design of the hollow form in which the container is formed.
  • the invention is based on the object of proposing a method of the type mentioned at the outset with which storage containers can be produced which, in relation to their space requirement, have a considerably larger capacity than the known storage containers which are dissolved in elementary containers.
  • the invention is also intended to propose design features for the container that are particularly advantageous for the basic concept.
  • a shape for the production of the container is also to be proposed by the invention.
  • the invention ensures that the elementary containers can be moved close together, preferably wall to wall, so that no unused space remains between the elementary containers. Further contributes to the better utilization of the space that the elementary containers are cuboid, so that there are no gussets between the elementary containers.
  • the arrangement of the connecting channels on edges instead of in the longitudinal center plane, as is the case with the known container according to DE-PS 2 758 838, is also an essential feature which contributes to the elementary containers being able to be joined together with or without a gap.
  • the invention is applicable not only for the production of containers in the blow molding process, but also for the production of containers in the rotary process.
  • the necessary plasticity can also be produced according to claim 4 by heating the connecting channels. Such subsequent heating is of course also possible with blown containers.
  • the elementary containers are placed against one another without a space.
  • small gaps may be appropriate, e.g. to allow an inspection of the elementary containers from the outside.
  • the method according to the invention is also particularly suitable for using the same shape to produce both independent elementary containers and larger containers which consist of two or more elementary containers, connection channels not being produced in the former case, while connection channels are formed in the case of larger containers.
  • the plastic plastic tube extruded into the mold is then squeezed in the space between two elementary containers. This enables a very efficient production of containers with single, double, triple, etc. capacity.
  • an elementary container can have a capacity of 1000 liters, so that containers with e.g. 1000 liters, 2000 liters and 3000 liters capacity can be produced.
  • cuboid should also be understood to mean containers which are strongly rounded at their edges, in particular at their vertical longitudinal edges, in order to maintain a high overall strength of the container at a given wall thickness.
  • the elementary containers can also have circumferential constrictions which further improve the strength.
  • substantially cuboid is thus intended to mean that a geometric cuboid is filled as completely as possible, taking into account the design features necessary for good strength, deviations in the volume of an elementary container from the volume of a circumscribing purely geome cubic cubic in the range of 5% to 15% of the volume of the geometric cuboid should be allowed and fall within the scope of the invention.
  • edges in particular side edges
  • edges it is generally not a question of edges in the narrower sense, but of the vertical corner regions of the elementary containers, which, as said, are rounded off with large radii can be and are then, for example, parts of cylindrical surfaces.
  • the cavities of the mold are preferably divided diagonally. With this type of division, the blow molding process extrudes the tube of plastic plastic material extruded between the mold halves as evenly as possible, thereby achieving a wall thickness that is as uniform as possible. This contributes to the saving of plastic material.
  • the inclination of the cuboid cavities to one another has the advantage that, after demolding, relatively small swiveling movements of the elementary containers are sufficient to bring them into the end position relative to one another.
  • the cavities can also be arranged relative to one another, which has the advantage that both halves of the shape are the same, as a result of which the shape can be produced cheaply.
  • Interchangeable insert parts can be quickly replaced with little effort, so that independent elementary containers or larger containers can be produced, which consist of several elementary containers, as required. So far, the transition to a different container size has involved extensive assembly work (removing a large and heavy mold and inserting a new, heavy mold, e.g. into a blow molding machine), which meant that a molding machine had to be down for a long time. The possibility of being able to produce different container sizes with the same mold is also a very important investment advantage, since such large molds are very expensive. Insert parts for a blow mold advantageously have a cavity for receiving displaced plastic material.
  • a special cuboid shape is advantageously provided for the elementary containers, namely the shape of a square column.
  • Containers shaped in this way are particularly advantageous in terms of strength, since all side walls have the same dimensions and the approximation to a cylindrical shape, which would be optimal in terms of strength, is particularly good.
  • the connecting channels can be shaped differently. They can have a flat, upright cross section. In this case, it is advantageous to support the large walls against one another by cusps molded onto them.
  • the connection channels can also have a circular cross section, in which case support bumps are not required.
  • the connecting channels preferably have corrugated walls, which facilitates the flexibility of the connecting channels.
  • Adjacent elementary containers are preferably locked together.
  • Various embodiments are specified in the claims for the formation of the lock.
  • the elementary containers engage in one another in a form-fitting manner, elevations on one elementary container engaging in recesses on the other elementary container.
  • the necessary nozzles are advantageously arranged on the ceiling of the elementary container concerned only on one elementary container. This is sufficient, since all elementary containers communicate with each other. On the other hand, it is advantageous to provide the possibility of attaching sockets to each elementary container, which is necessary if each elementary container is to be an independently usable container.
  • the storage container B consists of two elementary containers E i , E2, which communicate with one another via a lower connecting channel 1 and an upper connecting channel 2.
  • the elementary containers Ei, E2 and the connecting channels 1, 2 consist of a coherent piece.
  • the elementary containers E i , E2 have a relative position to one another, as is shown in FIG. 1.
  • the side walls 3, 4, which lie against one another later, run at an angle a to one another, which in the example shown is 45 ° .
  • the two elementary containers are fixed to one another in their swiveled-together position by locking points 7.
  • Two height-offset locking points 7 are preferably provided, which can be approximately at the height of the connecting channels 1, 2, for example.
  • the elementary containers are essentially in the form of a square column. However, where a square pillar has its longitudinal edges, there are roundings 8 which have a relatively large radius. In the lower third of each elementary container there is also a circumferential constriction 9; in the middle of the height of the constriction 9, each elementary container has a circular cross section. A ceiling 10 of each elementary container in turn merges with roundings 11 with a large radius in the container side walls. The container bottom 12 of each elementary container merges with edges 13 into the container side walls.
  • the shape described is essentially only the shape of a strictly geometric square column. The deviations described arise from the need to optimize the shape in terms of strength.
  • nozzles on the elementary container E2 There are three nozzles on the elementary container E2, namely a ventilation nozzle 14, a removal nozzle 15 and a filling nozzle 16. No nozzles are provided on the ceiling 10 'of the elementary container E 1 .
  • the storage container B can be produced both in a blow mold and in a rotary mold. In the following it is assumed that the container was produced by the blow molding process. Blow molds are shown in cross-section in FIGS. 4 and 5.
  • the shape designated overall by Fi consists of two mold halves 17, 18 which can be joined together on a separating surface 19.
  • the separating surface 19 runs essentially diagonally over the cavities Hi, H 2 and is bent over the edge 52, which roughly corresponds to the later bending line of the connecting channels 1, 2. This bend results from the fact that the cavities Hi, H 2 are to each other such that the angle ⁇ between the walls 20, 21 of the mold cavities Hi, H 2 is less than 90 °, in the present case, this angle is 45 °.
  • the mold contains insert pieces 22, 23.
  • the insert pieces have such a shape that there are 1, 2 mold connection channels 24 in the area of the connecting channels to be produced.
  • the mold halves 17, 18 are first moved far apart in the direction of the arrows 25, 26. Between the two mold halves, a hose is extruded in a blow molding machine, in which the mold F i is installed, and is still in a good plastic state initially hangs between the mold halves 17, 18. When the hose is completely extruded, the mold halves are moved together. After the mold has been closed, the space inside the tube is inflated, the tube wall being pressed against the inner walls of the cuboid cavities H 1 , H 2 .
  • the connecting channels 1, 2 also form.
  • connection channels 1, 2 can still be shaped, which can also be brought about in a targeted manner in that the shape in the area of the shape connection channels 24 is cooled less than in the rest of the area.
  • the elementary containers E 1 , E2 formed in the mold cavities Hi, H 2 are now brought into the relative position according to FIG. 2 to one another, as has already been described.
  • the necessary deformation of the connecting channels is relatively small because of the relatively small angle ⁇ , which is advantageous for the production.
  • the mold F 2 in FIG. 5 has mold halves 27, 28 which are of identical design.
  • the mold halves can be separated and joined together on a continuous separating surface 29.
  • the mold halves include cavities H ' 1 and H' 2 , which are oriented somewhat differently relative to one another than the cavities Hi, H 2 of the mold F 1 .
  • the angle ⁇ 'between the cavities is 90 ° here.
  • This arrangement has the advantage that the mold halves 27, 28 can be made the same. However, the connecting channels between the elementary containers then have to be deformed more than when manufactured in the form Fi.
  • the form F 2 contains inserts 30, 31 which separate the cavities H ' 1 and H' 2 from each other.
  • the mold F 2 could also contain moldings that leave mold connection channels between the cavities H ' 1 and H' 2 open.
  • Connectors 30, 31, which separate the cavities, are used when elementary containers are to be produced that can be used independently. In this case, of course, the necessary connectors must be molded onto both elementary containers.
  • the inserts 30, 31 and 22, 23 are quickly replaceable, as are the inserts for forming additional nozzles, so that a shape of manufacture is large with only minor conversion work ßer containers, which consist of several elementary containers, can be converted to the production of the smallest units, in which independent elementary containers are produced.
  • the inserts 30, 31 enclose a cavity 32 which is intended to hold plastic material which is obtained when the hose is squeezed.
  • the space 32 extends over the entire height of the cavities H ' 1 and H' 2 .
  • the connecting channel 1 (the connecting channel 2 is of identical design) has a flat cross section with large side walls 33, 34.
  • the side wall 33 merges into the side wall 34 via rounded portions 33a, 33b.
  • bumps 35, 36 are integrally formed on the side walls 33, 34. After a certain narrowing of the channel, these come into contact with one another and prevent further squeezing.
  • the clear cross section Q is at least equal to the cross section of the filling line which is to be connected to the filling nozzle 16. This ensures that communication between the two containers is possible without throttling, which hinders the compensation of the filling levels in the elementary containers.
  • the wall of the connecting channel is corrugated, which is shown in Fig. 7.
  • the bending axis lies approximately in the area of the inner side wall 34 of the channel 1.
  • FIGS. 8 and 9 a connecting channel 1 'is shown, which can be used instead of the channel according to FIGS. 6 and 7.
  • This connecting channel has a circular cross section, as can be seen from FIG. 8.
  • This channel also has a corrugated wall (see FIG. 9) with bead-shaped elevations 37 'and trough-shaped depressions 38'.
  • a connecting channel according to FIGS. 8 and 9 is dimensionally stable, so that there is no fear of crushing even when bending.
  • the ribbing which is formed by the elevations 37 and the depressions 38, also contributes to increasing the rigidity.
  • FIG. 10 and 11 show the formation of a locking point, as it is e.g. can be provided at 7 (see Fig. 2).
  • the eyes are offset in height such that they can overlap one another.
  • a connecting bolt 41 made of plastic is inserted through mutually aligned bores in the eyes.
  • the ends 41a, 41b of the bolt are crimped like a rivet, whereby the bolt 41 is axially secured.
  • the eyes 39, 40 are components of welded parts 42 of the same design. be injection molded from thermoplastic.
  • Each welding part 41 has a welding flange 43 which is connected to the container wall by welding.
  • the welding parts 42 are inserted into the blow mold. When the container is blown, the weld-on parts weld to the weld-on flanges 43 with the container wall.
  • the elementary containers Ei, E2 are held together by clips 44.
  • the clamp 44 engages around strips 45, 46, which in turn are components of weld-on parts.
  • the welded-in parts to be connected with the clamp 44 are at the same height, while in the embodiment according to FIGS. 10 and 11, as stated, there is a height offset.
  • the connection structures lie within a plane 47 which is applied to the side wall of the container.
  • FIGS. 14 and 15 which shows a further connection construction, also shows that there are two locking points above the height of the container.
  • the locking points described so far can be arranged at the same point as the straps 48, 49, which are used in the storage container according to FIGS. 14 and 15.
  • eyelets 50 and 51 are integrally formed on each elementary container, through which a belt 48 is pulled.
  • Two possible connection types are shown.

  • FIG. 16 shows a battery tank consisting of three containers B.
  • the elementary containers E i , E2 lie against one another without a gap, while there are distances 58, 59 between the individual containers B. This also enables a visual inspection of the container from the side. In principle, however, it is possible to omit the gaps 58, 59 to further save space. Since neither the connecting channels nor the locking constructions protrude laterally, the containers B can be moved closer together.
