Definitions
- the invention relates to a method for producing plastic container cells by injection molding according to the preamble of claim 1.
- Container cleaning machines for cleaning reusable containers, such as reusable bottles, are known in various designs. Within such a container cleaning machine, the containers are generally accommodated in container cells of container or bottle baskets guided through various treatment stations or zones in the interior of the container cleaning machine, wherein very different temperatures prevail within these treatment zones.
- the disadvantage here is that in the injection molding process only container cells can be produced reproducibly, the jacket of which has a sufficiently large minimum wall thickness, wherein the minimum wall thickness to be maintained depends on numerous factors, for example u.a. depends on the size of the container cells to be produced, the plastic material used, etc.
- the production by means of the injection molding process also does not allow the production of an outer contour of the container cells in any design and / or structuring, in particular it is necessary to avoid structures with undercuts that are not demoldable without a high cost of tooling costs. This is especially true for structures in the form of openings, Ausklin- kung, holes, even in the form of lattice or cage-like structures, etc. Due to these restrictive requirements of the injection molding can be, especially at an economically acceptable cost for the injection molding tools used only geometrically Produce simpler structures for container cells, with a substantially smooth and closed Be Strukturerzellenmantel.
- Object of the invention to show a method with which an inexpensive production of container cells with an optimized in terms of strength, mass and thus heat capacity design and / or structuring is possible.
- a method according to claim 1 is formed.
- first of all the production of a container cell blank which has at least the basic shape of the later container cell is, if possible, already formed with structures or design features, in particular also with those for the function and / or the attachment and / or the strength the subsequent container cell are necessary, but can be removed from the mold without difficulty in injection molding, so for example, have no undercuts, which lie in planes transverse to the axial direction in which the demolding of the respective container cell blank takes place in injection molding.
- this axis is the longitudinal axis of the respective container cell blank or the finished container cell.
- this blank is processed in terms of further optimization in terms of shaping and / or mass.
- This optimization is carried out, for example, by introducing openings and / or notches and / or openings and / or by removing material on surfaces to reduce the wall thickness, etc.
- the goal here is in particular the reduction of mass and thus the heat capacity of the container cell while maintaining the for the Use in a cleaning machine required strength.
- the invention is based on the finding that it is possible in a surprising manner by the at least one further step required following the injection molding of the blank to produce container cells which, with sufficient strength, have a greatly reduced heat capacity, and in that case the Additional costs of subsequent processing of the container cells alone are at least largely compensated for by the simplification of the mold used in injection molding, but in any case for the user of such container cells, these additional costs can be amortized by the savings achieved in energy costs already after a short time.
- the invention is further based on the finding that large portions of the surfaces and / or the lateral surface of container cells can be removed without detriment to their strength, whereby the heat content or the heat capacity is significantly reduced.
- a reduction of the mass and thus the heat capacity of the container cells by 25-30%, in a particularly advantageous embodiment even by 40-50% compared to the heat capacity of conventional, produced by injection molding container cells readily possible.

- FIG. 2 is a perspective detail view of a container cell;
- FIG. 3 shows the container cell of Figure 2 in side view.
- FIG. 4 shows a representation similar to FIG. 2 with another structuring produced by the aftertreatment
- Fig. 5 is a schematic block diagram for explaining the method according to the invention in the manufacture of the container cells.
- the container basket generally designated 1 in FIG. 1, consists essentially of a box-type cell carrier 2 made of sheet steel and of a plurality of bottle or container cells 3, which are respectively fitted in receptacles 2.1 of the cell carrier 2 and positioned in a secure manner against rotation are held.
- the container basket 1 is part of a container cleaning machine not shown for cleaning bottles or similar bottle-like containers and in particular part of a transport system of the container cleaning machine, which has a plurality of similar bottle baskets 1, with their cell carriers 2 at both ends with fastening tabs 2.2 on rotating transport elements, for example are held on circulating transport chains and with which the containers to be cleaned are moved through cleaning and treatment zones of the cleaning machine.
- the treatment of the container takes place at different temperatures, in such a way that the temperature of the container and thus the container baskets 1 and in particular the container cells 3 when passing the individual treatment zones, starting from a container task at which the container into the container baskets.
- each container cell 3 is composed of a tubular portion 4, which in the illustrated embodiment has a substantially polygonal or square outer and inner cross-section with rounded corners and in the illustration of Figure 1 at the top of the container basket 1 open is there or forms the open bottle or container cell end, as well as from an adjoining the section 4 downwards, frusto-conically tapered mouth region or section 5 together.
- a tubular portion 4 which in the illustrated embodiment has a substantially polygonal or square outer and inner cross-section with rounded corners and in the illustration of Figure 1 at the top of the container basket 1 open is there or forms the open bottle or container cell end, as well as from an adjoining the section 4 downwards, frusto-conically tapered mouth region or section 5 together.
- Against the inner surface of the section 5 is the respective received in the container cell 3 container with its mouth area.
- the container cell z. B. by locking twist-proof and held firmly on the cell carrier 2, in such a way that the portion 4 projecting with a portion above the top of the cell
- openings are provided in the wall of each container cell 3, in particular openings 6 in the section 5 which, in the illustrated embodiment, are in the longitudinal direction L of the container cell 3
- the section 4 at the top of the container cell 3 with a thickened, over the other outer surface of the container cell protruding edge region 8 trained.
- the container cell 3 is provided on the outer surface of the section 4 with a fastening structure, in the form of a slightly protruding edge 9 over the outer surface and in the form of locking lugs or locking strips 10 - 12.
- the production of the container cells 3 is carried out in one piece by injection molding of a suitable plastic and by a material-removing machining after injection molding, as will be explained in more detail below.
- each container cell 3 takes place according to FIG. 5 in at least two steps.
- an ingot 3a is first respectively produced with an injection mold or station 13.
- This blank 3a already has the basic shape of the container cell 3, consisting of the sections 4 and 5, wherein the respective blank 3a, for example, at least with a part of the necessary for the function and / or fastening and / or stability basic structure, ie is provided with at least a portion of the openings 6 and 7 and / or the reinforced edge portion 8 and / or the edge 9 and / or the latches 10, 11 and / or 12, as far as these functional element or structures are easily demoulded during injection molding.
- Each blank 3a produced is then subsequently material-removing or removing in a work station 14 according to a predetermined program, for example using at least one mechanical, material-removing tool, e.g. by milling and / or by water jet cutting and / or by laser cutting, preferably by laser cutting with a guided in a liquid or water jet laser beam, for example, for introducing openings and / or holes and / or openings and / or notches in the section 4 and / or 5 of the blank 3a and / or for the structured reduction of the wall thickness at the section 4 and / or 5 or at portions of these sections.
- the water cutting method, but also the laser cutting method and with a guided in a liquid or water jet laser beam allow reworking of the blanks 3a, with high operating speed without affecting the properties of the plastic material used for the production.
- the structures necessary for the function and / or attachment can be produced, in particular also those structures which would be difficult to demold.
- the post-processing in the processing station 14 to produce the openings 6 and 7, as well as the edge 9 and the locking lugs 10, the latter by reducing the thickness of the wall or section 4 between the edge 9 and the respective strip-like locking lug 10 or by introducing an opening 15 in the section 4 to form the edge 9 and the edge opposite strip-like locking lug 10.
- Other necessary for the function and / or attachment of the container cells 3 structures can be generated by the post , In particular, all structures that form perpendicular or transverse to the container cell longitudinal extent or axis-oriented undercuts.
- This subsequent patterning or processing of the blanks 3a in the work station 14 then takes place, for example, in such a way that grid, lattice, cage and / or rod-shaped structures for the container cells 3 result in the sections 4 and / or 5,
- the aftertreatment can take place in such a way that notches 16 are formed at the upper edge of section 4 and a grid-like structure consisting of a multiplicity of openings 17 and webs 18 lying therebetween is produced underneath.
- a grid-like structure consisting of a multiplicity of openings 17 and webs 18 lying therebetween is produced underneath.
- further slot-shaped openings 19 extending in the direction of the longitudinal axis L can also be introduced (FIG. 4).
- post-processing may cause a material erosion, i. a reduction of the wall thickness of the cell jacket takes place, as indicated by the hatched areas 20 in FIG.
- the inventive method with the production of the container cell blanks 3a by injection molding and subsequent material removal reworking of the blanks 3a makes it possible in a surprising manner, the container cells 3 inexpensive to produce with sufficient strength and greatly reduced mass and with greatly reduced heat capacity, the additional cost of the subsequent Processing of the blanks 3a can be at least partially offset by the simplification of the injection molds. Without affecting the function and / or the strength of the container cells 3, the mass and thus also the heat capacity of the container cells 3 by the inventive method in comparison to conventional plastic container cells in the same size by at least 25 - 30%, in particularly advantageous embodiments even by more than 40%, for example even be reduced by about 50%.
- a method according to the invention is likewise provided, in which the material chips or material sections or material residues arising during the processing of the container cell blanks (3a) are used for the production of new container cell blanks (3a). By doing so, it becomes possible to reduce the amount of plastic material required for manufacturing the container cell blanks (3a) and to further reduce the manufacturing cost.
