The technical field to which the invention relates.

The invention relates to a method of manufacturing cells for containers made of synthetic material by the method of injection molding according to the restrictive part of paragraph 1 of the claims.

The level of technology

Machine for washing reusable containers, such as bottles, reusable, well-known in different designs. In such washing machines for containers containers are located mainly in the cell recycle bins for cans or bottles, and the inside of the washing machine is transported through the various processing stations or zones, and within these treatment areas dominated by very different temperatures.

Thus, during the passage through the washing machine all turn around elements, i.e. not only be washing capacity, as well as cells for tanks, perceive the temperature prevailing in the individual treatment zones. This means that trash containers and bins for containers passing through different treatment area is first heated and then cooled, and thermal energy in a very significant amount is taken out of the treatment zones with a higher temperature to areas of lower temperature, without the possibility of effective use or return the desired SP is way in the desired amount imposed heat. For example, the temperature of the cells for tanks when tanks and output capacitances of the washer is about 35-40°C and reaches in treatment areas with high temperature, for example in alkaline baths, approximately 80°C.

As the washing machine for containers of medium size has generally 15000-20000 cells for bottles and during operation of the washing machine each cell for capacity turns out 3-4 times per hour, due to heat losses, which are cells for tanks of the treatment zones with high temperature in the treatment area with a lower temperature, to be a very significant thermal losses.

Already, attempts were made to reduce heat or energy losses to reduce the heat capacity of the cells for tanks, namely, by reducing the mass and the heat capacity through the use of synthetic material, e.g. a manufacturing cell for tanks by way of injection molding of synthetic material.

This has the disadvantage that the method of molding pressure can be produced in a reproducible manner only cells for tanks, a casing which has a sufficiently large minimum wall thickness. Moreover, subject to maintaining the minimum wall thickness depends on numerous factors, among other things, on the size of the liable the manufacturing cell for capacity, from applied synthetic material, etc.

Fabrication using the method of molding is not possible to avoid also works on forming the outer contour of the cells in the vessel of any shape and/or structure, in particular, when you need to, structures with openings that cannot be formed without the high cost of the instrument. This also applies to structures in the form of holes, boundary cuttings, holes, as well as structures having the form of grids or cells. Because of these limiting aspects of the method of injection molding, in particular, at economically acceptable costs on tools for a method of molding can be made only geometrically simplified structure for cells for tanks, namely, mainly with a smooth and closed body cells for capacity.

Disclosure of inventions

The objective of the invention is to provide a method and invention is an inexpensive manufacturing cells for tanks with optimized in terms of strength, mass, and this heat will form and/or structure. The technical result is achieved in the way of signs of paragraph 1 of the claims.

When proposed according to the invention the method of manufacturing the first is the manufacture of harvesting cells for capacity that is less than the least has the basic shape of the future cell for capacity, but possibly formed with structures and signs the form, in particular such that are needed for operation, and/or fixing and/or durability of the future for cell capacity and can easily removed from the mold when injection molding, ie, for example, do not have any cut-outs, which lie in planes orthogonal to the axis direction in which the molding is to be extracted from the shape of the corresponding blank cell for capacity. This axis, as a rule, is the longitudinal axis of the corresponding blank cell for capacity or made entirely of cell capacity. In the subsequent processing that may be performed on the stage of the way or in several partial steps, in this case, the workpiece is processed, subject to further optimization regarding the formation and/or mass. This optimization is carried out, for example, using hole punching, and/or regional deforestation, and/or apertures and/or by removing material on the surfaces to reduce the thickness of the walls, etc. the Goal is to reduce the mass and with it the heat capacity of the cells to the vessel while maintaining the strength required when using the washing machine.

The technical result is also that with the help of the, at least another operational step performed immediately after injection molding of the preform, it is possible to produce cells for containers that with sufficient strength are significantly reduced heat capacity, and additional costs for additional treatment of the cells themselves to capacity, at least for the most part compensated for using the simplify tool used in injection molding. For the user of such cells for tanks these additional costs are amortized within a short time through savings on energy production and its receipt from the outside.

A large part of the surfaces and/or surface of the body cells for tanks can be removed without compromising their strength, so that the enthalpy or heat capacity decreases significantly. In particular, using proposed according to the invention how without difficulty it is possible to reduce the mass and the heat capacity of the cells for tanks 25-30%, in a particularly preferred case, even by 40-50% compared with the heat capacity of existing manufactured using injection molding cells for containers.

Brief description of drawings

Below the invention is explained by using the drawings, in which:

figure 1 is a simplified perspective partial picture of the trash containers,consisting of carrier cells with multiple provided on the media bins for bottles or containers;

figure 2 is a perspective image of a single cell for capacity;

figure 3 - cell for capacity figure 2, a side view,

4 is an image similar to the one shown in figure 2, and the other obtained by the processing structure;

5 is a block diagram for explanation of proposed according to the invention, a method of manufacturing cells for containers.

The implementation of the invention

The figure 1 shows the basket 1 for tanks, consisting of mostly made of steel sheet having a box carrier 2 cells and multiple cells for 3 bottles or containers, which respectively are properly seated in the receiving device 2.1 media 2 cells and fastened it securely against twisting and fixed in position.

Basket 1 for tanks is part of a not shown machine for washing bottles or the like containers formed in the form of bottles, and a special part of the transport system of the machine for washing containers, which has a large number of such baskets 1 for tanks, which with their carriers 2 cells, respectively, on both sides by means of fixing planks 2.2 fixed on the rotating transport elements, for example on a rotating chain conveyors, and with which to be washing capacity on Igusa through the zones of washing and handling of the washing machine. The treatment zones are processing capacities at different temperatures, namely, so that the temperature of the containers and with them also baskets 1 for tanks and, in particular, cell 3 for tanks with the passage of the individual treatment zones, from the loading of the containers in which the containers are installed in basket 1 for tanks, first increases and before reaching the unloading of containers, in which the washed containers are retrieved from the baskets 1 for tanks, decreases again. Consequently, during each turn there is a heating and subsequent cooling of baskets 1 for tanks and cells 3 for tanks, for example, between temperatures in the range from 35 to 40 to 80°C, and thus there is significant removal of thermal energy from the treatment zones with high temperatures in the contiguous treatment area at a lower temperature. This made the heat energy, which, as a rule, cannot be used or in any case may not only be used with considerable cost, to a great extent also depends on the mass and the heat capacity of the cells for 3 tanks.

In General, the morphology of the cells for 3 tanks roughly fitted to the shaping is subjected to washing tanks or bottles, i.e. the casing or wall of each cell 3 in the vessel consists of a tubular section 4, in which pre is submitted to the form of implementation has mainly polygonal or square outer and inner cross-section with rounded corners and in the image in figure 1 is open on the upper side of the basket 1 for tanks or forms there open ends of the cells for bottles or containers, as well as from narrowing, which has the shape of a truncated cone the collar area or portion 5 adjacent to the bottom section 4. To the inner surface of the section 5 adjacent, respectively, located in cell 2 capacity with your neck area. Plot 4 cell for capacity, for example, by clamping is stationary in rotation and fixed on the carrier 5 cells, namely, so that the area 4 with a partial section protrudes above the upper side of the carrier 2 cells, and section 5 is placed at the bottom side of the carrier 2 cells.

To make it possible to process a suitable container located in the cell to the vessel, the walls of each cell 3 for tank openings are provided, namely, in particular, the holes 6 in section 5, which presents the form of the implementation is made in the form of slots extending in the longitudinal direction L of the cell 3 to the tank, as well as a large number of holes 7 in the bottom part of parcel 5. To strengthen the open end of the cell for bottles or containers section 4 on the upper side of the cell 3 for containers formed with thickened serving for the rest of the outer surface of the cell for tanks marginal region 8. Next, the cell 3 for capacity on the outer surface of the section 4 is equipped with prochnau the second structure, namely slightly protruding beyond the outer surface of the belt 9, and also in the form of ledges or strips 10-12 for fixing. Manufacturing cells for 3 tanks is carried out as a whole by using injection molding of a suitable synthetic material and by processing after molding, which consists in removing material, as is explained in more detail below.

To make the mass and heat capacity of the cell 3 for tanks if possible, low and with this the amount of heat removed from the washing machine from the treatment zones with a higher temperature in the treatment area with a lower temperature, namely, when the possibility of manufacturing cells for 3 tanks simplified way of injection molding or by using a simpler tool for injection molding, the manufacturing of each cell for capacity, respectively figure 5 is provided at least in two stages.

At the first stage in the form for casting under pressure or at the station 13 is first produced, respectively the workpiece 3A. This preparation 3A already has the basic shape of the cell 3 to the vessel, namely, consists of sections 4 and 5, and the corresponding workpiece 3A, for example, is equipped with at least part of the basic structure necessary for the operation and/or hardening, and/or sustainability, i.e. at least part of atverti and 7, and/or reinforced edge region 8, and/or edge 9, and/or stops 10, 11 and/or 12, how these elements or structures for the operation can be formed. Each manufactured workpiece 3A in this case is then processed on a workstation for a given program with the withdrawal or removal of material, for example, applying at least one mechanically removing the material of the tool, such as milling and/or cutting water jet and/or laser cutting, mainly laser cutting with a laser beam directed into the stream of liquid or water, namely, for example, to create holes and/or holes and/or apertures and/or regional deforestation in section 4 and/or 5 of the workpiece 3A and/or structured to reduce the thickness of the wall section 4 and/or 5 or in partial areas of these sites. Ways of cutting water, and how laser cutting and laser beam directed into the stream of liquid or water, allow additional processing of the workpieces 3A high speed without damaging the properties of the synthetic material used for manufacturing.

With additional processing can be created structures necessary for the functioning and/or hardening, in particular, such structures could be formed with difficulty. So, for example, with the help of additional the of processing on the workstation 14 can drill holes 6 and 7, as well as to form the edge 9 and the axial projections 10, namely, the latter by reducing the wall thickness or area 4 between the edge 9 and having a form corresponding strap resistant ledge 10 or by punching holes 15 in section 4 for the formation of an edge 9 and lying against the edge with a view of the strap of the thrust ledge 10. With additional processing can also be created and other structures necessary for the operation and/or hardening of cells 3 for containers, in particular all the structures that form the elements obtained by cutting, oriented perpendicular or transverse to the longitudinal extent of the cell containers or axis.

In addition to these structures necessary for the operation and/or hardening of cells for containers that can be manufactured by molding only with difficulty or only with a great tool cost, with additional processing other structures are formed to reduce the weight and the heat capacity, namely, again by creating holes and/or apertures and/or regional deforestation and/or removal of material, etc. so as not to cause damage to the functioning and strength of the cell 3 to the tank. This additional structure or processing of the workpiece 3A is carried out on a workstation 14, in this case is, for example, in the form of a mesh, grid, cell, and/or truss structures for the cells for 3 tanks on stations 4 and/or 5, namely, it is preferable structures that are distributed throughout or at least in the greater part of the volume of the lateral surface and/or extend in the longitudinal direction L or mainly in the longitudinal direction of the corresponding cell 3 for capacity on the largest possible length of the cell capacity.

For example, additional processing may be performed so that the upper edge of the section 4 are formed cutting edge 16 and the underlying lattice structure consisting of a large number of holes 17 and lying between them jumpers 18. In addition to having the form of a splined hole 6 can be formed even other shaped spline hole 19 extending in the direction of the longitudinal axis L (figure 4). In addition, by using additional processing can be performed removing the material, i.e. the reduction of the wall thickness of the body cells, as shown by the shaded areas 20 in figure 3.

Proposed according to the invention a method of manufacturing billets cells for tanks 3A by way of injection molding and subsequent processing of the workpiece 3A, associated with the removal of material, allows inexpensive manufacture of the cell 3 for tanks with sufficient p is acestu and with significantly reduced weight, and, thus, with greatly reduced heat capacity, and additional costs for additional processing of the workpieces 3A can at least partially be compensated by simplifying tools for injection molding. Without prejudice to the operation and/or strength of the cells 3 for vessels using the proposed according to the invention in comparison with existing cells for containers made of synthetic material can be reduced mass and, thus, the heat capacity of the cells for 3 tanks equal to the value of at least 25-30%, with a particularly preferred version even more than 40%, for example, even at about 50%.

According to the invention is provided in the way the use of chip material, or portions of material, or material residues, resulting in the processing of workpieces (3A) cells for tanks, for the manufacture of new pieces (3A) cells for tanks. This makes it possible to reduce the amount of synthetic material needed for the manufacture of preparations of cells (3A) for tanks, and even more to reduce the cost of manufacturing.
