Description

The invention relates to a washing machine according to the restrictive part of paragraph 1 of the claims.

Washing machines for bottles or vessels of this kind are known in various embodiments. In principle, machines of this kind represent an infinitely rotating drive transport system located inside the machine with a large number of cells for bottles or vessels for accommodating a vessel, respectively. They move through the transport system from the bottle inlet through several treatment zones or sections before they, in the form of washed vessels, enter the vessel outlet of the washing machine. At least one treatment zone (spray zone) is used to spray or pre-spray the vessels, in particular their outer or lateral surface, to remove labels, label residues or other adhering contaminants before the vessels are transported in this case to another treatment area, such as a dipping bath. In the spraying zone, the vessels with their vertically oriented axis are located vertically or mainly vertically in the vessel cells open on the lower side, and at the same time slide at least one sliding surface with their bottom part, which is usually formed by a sliding grid . Spraying vessels is carried out using spray nozzles from above. A disadvantage of the known washing machines is that in this spraying zone, damage to the vessels in their bottom part often occurs, but in particular, the labels on the sliding grating are also blocked and the vessels are blocked and skewed.

The objective of the invention is to provide such a washing machine in which, due to the corresponding execution of at least the process in the treatment zone formed as a spray zone, damage to the vessels in the bottom is prevented, as well as, in particular, warping, blocking of the vessels and / or labels. To solve this problem, a processing machine is proposed in accordance with the characteristics of paragraph 1 of the claims.

Due to the embodiment according to the invention of at least one sliding surface in the form of a sliding edge or sliding cross-section, which clearly protrudes above the rest of the sliding grating, free space is formed under the sliding surface for continuous removal of labels, label residues or other foreign substances.

Due to the sliding surface having the shape of a cross member or plate, a directional change in the position of the vessels in the vessel cells during the passage of the treatment zone is also possible, which greatly improves the accessibility of the outer or side surface during spraying and thereby the quality of the treatment. Further, thanks to the invention, it becomes possible in this way to select the material for the sliding surface or for the part forming the sliding surface with respect to the material of the vessels, so that the optimum sliding properties for the vessels are obtained and due to this, damage to the vessels is effectively prevented.

Improvements, advantages and applications of the invention result from the following description of embodiments and from the figures. Moreover, all described and / or graphically presented features in themselves or in any combination are, in principle, the subject of the invention, regardless of their annotation in the claims or their relationship. Also, the content of the claims is an integral part of the description.

The invention is further explained in more detail using the figures in the examples of implementation, which show

FIGS. 7 and 8 are a side view (FIG. 7) and a top view (FIG. 8) of one of the details of the slide grid according to another embodiment of the invention.

Figure 1 shows the processing zone of the otherwise not shown washing machine of vessels or bottles, which, in a manner known to the person skilled in the art, includes an infinitely circulating drive transport system, with which the bottles 2 move through several zones between the place of loading of the bottles to be washed and the place of unloading of washed bottles processing, including through processing zone 1. It is used to spray bottles 2, in particular their outer or lateral surfaces, to remove existing labels, label residues or other contaminating materials.

The transport system includes, in a manner likewise known to the person skilled in the art, on infinitely circulating drive chain conveyors 3 a large number of bottle baskets 4, which respectively have several adjacent to each other perpendicular to the direction A of transporting the cells 5 for bottles for placing respectively one bottle to be washed 2. Cells 5 for bottles, which in the processing zone 1 with their axis are oriented respectively in the vertical or mainly vertical direction, have a shape shaped to bottles 2, and form on their top end shown in FIG. 1 a lattice structure having a large number of holes, which in other processing zones serves as a support for the neck 2.1 of bottle 2. On its bottom shown in FIG. 1 end of cell 5 for bottles open. The axial size, as well as the internal cavity of the cells 5 for bottles is slightly larger than the height, as well as the maximum diameter of the bottle 2.

In the treatment zone 1, above the path of movement of the basket 4 for bottles, an atomizer pipe 6 with spray nozzles 7, oriented with its axis in the horizontal direction and perpendicular to the transportation direction A, is provided to create spray nozzles 8 for washing liquid, for example, water or alkali. In this case, the nozzles 7 are oriented so that at least one downward spraying torch 8 is fed through each nozzle 7 to the bottle cells 4 moving past under the nozzle 7. The number of spray nozzles 7 is at least equal to the number of cells 5 for bottles of each basket 4 for bottles.

The spray pipe 6 is, for example, stationary. In principle, it is also possible that the nozzle pipe 6 and / or its nozzle 7 can be movable in such a way that the corresponding spray torch 8 in a short section moves together with the corresponding bottle cell 5.

When passing through the processing zone 1, the bottles 2 located in the cell 5 for the bottles glide with their bottom 2.2, protruding from the lower open end of the cell 5 for the bottles, on a sliding grid or grating 9, due to which labels can be separated by jets 8 from the bottles 2, label residues, contaminants, etc. together with the washing fluid through the sliding grate 9, should be taken under the path of the cells 5 for bottles. With respect to the transport direction A, in front of the treatment zone 1 or in front of the sliding grating 9 and after the processing zone 1 or after the sliding grating 9, the bottles 2 with their bottom parts 22 of the bottles move along the slide guides 10 and 11, which, for example, are also formed in the form of lattice structures or perforated slip sheets.

In order to prevent damage, in particular due to blocking by labels or label residues, and to improve the processing of bottles 2 in the processing zone 1, the sliding grating 9 is formed with a special sliding structure, which during processing makes it possible to change the position of the surfaces 2 in the bottle cells 5 when the passage of the treatment zone 1, namely in such a way that a particularly effective treatment of the outer or side surface of the bottles with the corresponding spray torch 8 is obtained. The lattice structure in the embodiment shown in FIGS. 1 and 2 is formed by several plate-like sliding parts 12, which are oriented along the longitudinal direction L in the transport direction or mainly in the transport direction, and of which respectively the sliding part is located in the middle of the cell 5 for bottles. The number of sliding parts 12 is thus at least equal to the number of rows or groups of bottle cells extending respectively in the transport direction A.

Each sliding part 12 forms an edge-shaped or plate-like sliding surface 13, to which the bottles 2 are adjacent with their bottom part 2.2 and which has a section 13.1 rising one after the other from the sliding surface 10 in the form of a ramp and a lowering section adjoining it in the form of a ramp 13.2. and from it, the portion 13.3 rising again in the form of a ramp, which ends at or slightly above the level of the adjoining sliding surface 11. In all sections 13.1-13.3, the plate-like sliding surfaces 13 of each sliding part 12 are open, i.e. in all sections 13.1-13.3, the level of the plate-like sliding surface 13 of each sliding part 12 is higher than the level of the adjacent region of the sliding grating 9, so that the bottles 2, when passing the treatment zone 1 with their bottom part 2.2, glide exclusively on the sliding surfaces 13 of the sliding parts 12.

Due to the differently inclined sections 13.1 and 13.2, the aforementioned change in the position of the bottles 2 occurs during the passage of the spray torch 8 due to the raising and tilting or rotation of each bottle 2. The transition between the sections 13.1 and 13.2 is in the presented embodiment somewhat lower than the corresponding spray nozzle 7. The sliding surfaces 13 or their projection surfaces have a width in the range of about 2 to 15 mm.

As shown in particular in FIG. 2, the slide grate 9 in this embodiment consists of several, for example, made of metal flat material, for example, special steel, elements 14 and 15 of the slide grate, which are provided with recesses 14.1 or 15.1 forming the holes of the grate 9 of the slide, the elements are adjacent to each other in the horizontal direction and perpendicular to the direction of transportation A and between themselves take the details 12 of the slide, which with their surfaces 13 of the slide noticeably protrude above the plane e elements 14 and 15.

Replaceable sliding parts 12 are mounted on the sliding grating 9 and consist, at least in the area of their sliding surfaces 13, of the material providing optimal sliding properties for bottles, for example, synthetic material, in particular polypropylene, polyvinyl chloride, high density polyethylene. For detachable or replaceable fastening, the sliding parts 12 are respectively made with a fastening section or shoe 16, which in the embodiment shown in Figs. 1 and 2, for example, lies in a plane with the rest of the corresponding sliding part 12 and is secured with suitable fasteners, such as screws, locking pins or snap-in or locking joints with elements 14 and 15 or with mounting plates or sections provided thereon.

The sliding grating 9, mainly consisting of elements 14 and 15 of the sliding parts 13, is provided in the washing machine with the possibility of removal, for example, in the form of a complete structural element or in the form of individual elements, for example, by hanging or by sliding, for example, across direction A of transportation. Further, the elements 14 and 15 can be made integral with the lattice, and in this case, the elements 14 and 15 form the base elements of the sliding parts 12.

Figures 3 and 4 show a side view, respectively, a top view of the sliding part 12a, which again forms a sliding surface 13 with axially located (longitudinal axis L) adjacent sliding surfaces 13.1-13.3, but. different from the sliding part 12 in that the sliding part 12a for its fastening is formed integrally with a plate fastener or base element 16a, which in this form of implementation extends along the entire length of the sliding part 12 and is oriented with its sides of the surface perpendicular to the sides of the surface of the part 12a a slip forming a sliding surface 13 and protrudes away from the sliding part 12a. When using suitable fasteners, the sliding part 12a is fixed, for example, on the upper side of the flat cross members 17 of the sliding grating, namely, in such a way that when viewed from above on the sliding grating between each sliding part 12a and an adjacent element, for example, another cross-member 17 or detail 12a the sliding lattice of the slide remains a gap 18 of sufficient width, i.e., for example, with a width that is approximately equal to or preferably greater than the width of the base element 16a.

Following the passage of section 13.2, also the base element 16a approximately at the transition between sections 13.2 and 13.3 is thus bent so that the lower side of the support element 16a, facing away from the sliding surface 13, is formed by two sections, one after the other in the longitudinal direction of the sliding part, which form each other with the other, the angle is slightly less than 180 °, which opens to the upper side of the sliding part 12a having a sliding surface 13.

Figures 5 and 6 show a side view, respectively, from a top view of the sliding part 12b, which again has an upper sliding surface 13 with axially arranged (longitudinal axis L) and adjacent to each other sections 13.1-13.3. The sliding part 12b differs from the sliding part 12a in that there are two fastening sections, respectively, of the base member 16b, of which one extends, respectively, about half the length of the sliding part 12b. Both base elements 16b protrude above different sides of the surface of the plate sliding part 12b. Associated with the transport direction A, the second base member 16b has a bevel 19 at its front end associated with the transport direction A.

At the sliding part 12b, the planes of the lower sides of both base elements 16b facing away from the sliding surface 13 form exactly the same angle slightly less than 180, which opens to the upper side of the corresponding sliding part 1b.

FIGS. 7 and 8 show a side view and a top view of the sliding part 12, as another embodiment that differs from the sliding parts 12, 12a 12, 12a and 12b in that the sliding surface indicated in 13 by 13c, in a partial section also extends horizontally across or with a bevel towards direction A of the transport. In particular, the sliding surface 13 c has, in the transport direction A, one after the other: a ramp 13c.1 rising in the form of a ramp and extending in the transport direction A;

adjacent to it further in the form of a ramp rising and in its projection obliquely passing to the transport direction A from the middle of the base element 16c towards the edge of the section 13c.2; adjoining it in the form of a ramp and lowering in its projection exactly the same passing obliquely to the direction of transportation, as well as section 13c.3 equiaxial with section 13c.3; adjacent to it in the form of a ramp rising, in its projection, going backward with a bevel to the direction A of transportation, as well as to the middle of the base element 1bc, section 13c.4; as well as the ascending section 13c.5 adjacent to it further in the form of a ramp, which in its projection extends in the transport direction A and is located equiaxially with the section 13c.1 in the longitudinal axis L. Due to the orientation partially horizontally or mainly horizontally transverse to the transport direction A the passage of the plate-like sliding surface 13c in the sections 13 c.2-13c.4 is carried out in addition to the above described in connection with the sliding surface of the sliding part 12, the capsizing of the bottles 2 mainly around the axis to the transport direction A at the same time also tipping of these bottles around the axis parallel or mainly parallel to the transport direction A and with it further improving the processing of the bottles 2 in the processing zone 1.

In order to ensure as gentle as possible the sliding of the bottom parts of 2.2 bottles on the sliding surface 13, it is also inclined laterally in sections 13c.2-13c.4.

In the sliding parts 12a-12c, the width of the sliding surface 13 or 13c or their projection surface is again from about 2 to 15 mm. The width of the corresponding base element 16a-16c or its projection surface lies in the range between about 25 and 45 mm, so that the ratio of the width of the sliding surface 13 or 13 s to the width of the base element 16a, 16b or 16c is from 1/3 to about 1/5 .

The invention has been described above with reference to exemplary embodiments. It is understood that numerous changes as well as modifications are possible while maintaining the inventive idea underlying the invention.
