Description

A GLASS PLATE CLEANING APPARATUS
D E S C R I P T I O N
Field of application
The present invention is generally applicable to the field of glass processing machines and particularly concerns a washing apparatus for glass sheets.
State of the art
In a production line of glass sheets one of the stations consists of the washing apparatus for the produced sheets. Such washing is indispensable not only for aesthetic needs, but also and above all to eliminate processing residues and make the glass usable for often delicate subsequent processing.
Washing of flat glass sheets is generally not very complicated thanks to the arrangement of the glass and its shaping. In the prior art, in fact, the glass is generally arranged horizontally on conveyor belts and washing takes place on the upper part. Subsequently the glass is turned over and the opposite surface is washed.
Since the glass sheets are notoriously fragile, the need to carry out the washing with as few movements as possible is evident.
In this sense, in the known art it has been thought to use a pair of rollers that move on the two sides of the glass plate. However, to carry out such an operation the sheet must be kept upright, and this implicitly subjects it to greater risks of breakage.
brushes with specific shaping.
Presentation of the invention
The object of the present invention is to overcome at least partially the drawbacks mentioned above by providing a glass sheet washing apparatus which allows any type of sheet to be washed, whatever the shaping, subjecting the sheets themselves to the lowest possible risk of breakage.
In particular, an object of the invention is to provide a washing apparatus which allows to operate on the glass sheets by washing them with a lower or at least equal number of movements of the known equivalent apparatuses. In particular, another object of the invention is to provide a washing apparatus which allows the washing of the glass sheets keeping them in a horizontal position.
A further object of the present invention is to provide a washing apparatus which in any case allows the washing of both surfaces of a glass sheet without having to turn it on itself.
Said objects, as well as others which will become clearer in the following, are achieved by a glass sheet cleaning apparatus according to the claims that follows which are to be considered as an integral part of the present patent.
In particular, the cleaning apparatus comprises a support and transport assembly for a glass sheet as well as one or more washing elements of the sheet.
According to another aspect of the invention, the support and transport assembly comprises a plurality of first rollers rotatable according to an axis of longitudinal development arranged substantially vertical to the ground. In this way, advantageously, the glass sheet, which is arranged in abutment on these first rollers, is in a horizontal position during washing.
The first rollers are therefore sized to support and transport the glass sheet in the cleaning apparatus according to a direction of advancement within the apparatus itself.
According to another aspect of the invention, the first rollers are arranged according to two parallel orders spaced apart from each other to identify, between these two orders, a gap.
Advantageously, therefore, the gap between the first rollers allows accessibility to the lower surface of the glass sheet. It follows, again advantageously, that both the surfaces of the glass sheet, the upper and the lower, are immediately reachable for washing, thus avoiding potentially dangerous movements.
Moreover, still advantageously, this also allows the two surfaces of the glass sheet to be washed simultaneously, thereby reducing the operating times of such operation.
Brief description of the drawings Further features and advantages of the invention will become more evident in light of the detailed description of a preferred but not exclusive embodiment of a glass sheet cleaning apparatus according to the invention, illustrated by way of non-limiting example with the aid of the accompanying drawings wherein:
FIG. 1 represents a washing apparatus according to the invention in a front view;
FIG. 2 and 3 represent details of the apparatus of FIG. 1.
Detailed description of some preferred embodiments
With reference to the mentioned figures, and in particular to fig. 1 , a glass sheet cleaning apparatus 1 is described.
The apparatus 1 of the invention can be used indifferently within a glass sheet production line or as a single device.
According to an aspect of the invention, the cleaning apparatus comprises a support and transport assembly 2 for a glass sheet. Such assembly not only allows to support the sheet to be washed but moves it from the inlet of the washing apparatus 1 to the outlet. In this sense the support and transport assembly 2 typically comprises motor drive means 3.
According to another aspect of the invention, the washing apparatus comprises a pair of washing elements 5 of the glass sheet. These are arranged so as to operate from opposite sides of the sheet. In this way, therefore, the advantage of washing the glass sheet simultaneously on both surfaces thereof is obtained, with a consequent decrease in the execution times of the washing with respect to known equivalent apparatuses.
Typically, the washing elements 5 consist of brushes, but this aspect should not be considered as limiting for different embodiments of the invention where the brushes can be replaced or integrated with other washing elements such as, for example, fluid pressure spraying nozzles.
Also, the number of washing elements 5 in a feature that is not to be considered as limiting for the present invention.
According to the prior art, the transport assemblies consist of rollers at least as long as the glass sheets to be washed are large. In this sense, the sheets are arranged in abutment ensuring safety during treatment. However, it has previously been stated that the apparatus 1 of the invention acts simultaneously on both faces of the glass sheet by means of the washing elements 5. This condition, according to the prior art, is admissible only if the sheets are arranged standing and laying down on the support and transport assembly 2.
Since this would expose the glass sheets to greater risks of breakage, according to an aspect of the invention the support and transport assembly 2 comprises, as can be seen in the detail of fig. 2, a plurality of first rollers 10 rotatable according to an axis of longitudinal development arranged substantially horizontal to the ground. Moreover, the first rollers 10 are sized to support and transport the glass sheet in the cleaning apparatus 1 according to a direction of advancement within the apparatus 1 itself.
In order to improve the aforementioned situation, i.e. to arrange the sheets laying down and not standing, according to another aspect of the invention the first rollers 10 have a shorter length than the width of the glass sheet and are arranged according to two parallel orders 11. Moreover, such two orders 11 are spaced apart so as to have a gap between them. In this sense, when the glass sheet to be washed is laid thereon, each of the side edges thereof abuts on a respective order 11.
Advantageously, therefore, in the interspace between the two orders 11 of first rollers 10 one of the two washing elements 5 can act, thus reaching the lower surface of the glass sheet to be washed.
Such washing, still advantageously, takes place in any case safely due to the laid position of the glass sheet. Moreover, still advantageously, the glass sheet is washed on both sides without require any movement which could put it at risk of damage.
According to another aspect of the invention, the support and transport assembly 2 also comprises a plurality of second rollers 14 rotatable according to an axis of longitudinal development arranged substantially vertical to the ground. Also, these second rollers 14 are arranged according to two parallel orders 15 spaced apart from each other. In particular, they can be identified close to the respective two orders 11 of first rollers 10.
In this sense, when the sheet is arranged in abutment on the first rollers 10, the two orders 15 of second rollers 14 are laterally in contact with the side edges of the glass sheet to be washed. Advantageously, therefore, they not only cooperate in advancing the glass sheet, but hold it in position both during washing and during transport.
According to a further aspect of the invention, the first roller 16 of each order 15 of the second rollers 14 is movable in a direction transverse to the direction of advancement of the glass sheet. In other words, the first 16 of the second rollers 14 are expandable, i.e. their mutual distance is variable. In this way, advantageously, the horizontal insertion of the glass sheet to be washed is facilitated.
However, this latter aspect of the invention should not be considered as limiting. Not only, in fact, there may be no second rollers 14 movable according to the direction transverse to the direction of advancement of the glass sheet, but also the number of second rollers 14 with this feature can be anyone.
According to a further aspect of the invention, the apparatus also comprises a pair of mechanical arms 20. One of these mechanical arms 20 is represented in detail in fig. 3.
At their free end 21 a respective washing element 5 is stably coupled. There is also a programmable logic unit 22 operatively coupled to the mechanical arms 20 to control its movement. In this way, advantageously, the washing of the sheet by the washing elements 3 is controlled by the programmable logic unit 22.
This allows, still advantageously, to automate the washing by controlling the mechanical arms 20 and making this operation optimized, eliminating the possible human error.
According to another aspect of the invention, the apparatus 1 also comprises a data entry device, not shown in the figures, used to insert data into the programmable logic unit 22. Such data include, in particular, data relating to the shaping and dimensions of the glass sheet to be washed.
Advantageously, therefore, the programming of the logic unit 22 allows washing to be carried out on any glass sheet and, in particular, on sheets of any shaping, while still ensuring uniform cleaning. It will be sufficient to modify the programming of the logic unit 22 to adapt the control of the mechanical arms 20 to the particular shaping and dimension of the sheet to be washed.
According to a variant embodiment of the invention, moreover, this data entry device comprises a plurality of sensors which detect dimensions and shaping of the sheet and whose measurements are subsequently converted into instructions for the correct control of the mechanical arms 20.
This advantageously enables the washing apparatus 1 of the invention to be adapted automatically from time to time to the sheet to be washed.
According to a further aspect of the invention, the programmable logic unit 22 is also programmed to control the simultaneous action of the pair of washing elements 5 on the same portion of the glass sheet and on opposite sides.
Advantageously, consequently, the pressure exerted on the sheet by a washing element 5 is always balanced by the equal and opposite pressure exerted on the same portion of sheet by the other washing element 5. Consequently, again advantageously, the washing elements 5 can exert any pressure on the sheet without fear of breakages and at the same time ensuring an optimal and uniform cleaning of the sheet.
It is clear, however, that this configuration is admissible precisely due to the spaced arrangement of the two orders 11 of the first rollers 10.
After washing the glass sheet, it is advisable to proceed with drying.
In this sense, the cleaning apparatus 1 comprises a pair of drying elements 25 which can operate from opposite sides of the sheet operatively downstream of the washing elements 5.
Furthermore, such drying elements 25 are stably coupled to the free ends 26 of an additional pair of mechanical arms 27. In other words, advantageously, also the drying elements 25 are managed as the washing elements 5. In particular, also the additional pair of mechanical arms 27 is operatively connected to the programmable logic unit 22 which controls the contemporary action thereof on the same portion of the glass sheet and on opposite sides. In this way the drying does not subject the sheet to excessive stresses whatever the method with which it is carried out.
Typically, the drying elements 25 are constituted by conveyors of hot air under pressure, but also this aspect should not be considered as limiting for the present invention.
In light of the foregoing, it is understood that the washing apparatus of the invention achieves all the prefixed purposes.
In particular, it allows to wash any type of sheet, whatever the shaping, subjecting the sheets themselves to the lowest possible risk of breakage.
On closer inspection, in fact, the apparatus of the invention allows to operate on the glass sheets by washing them with a lower number of movements or at the most equal of the known equivalent apparatuses. The sheets are washed keeping them in a horizontal position and without having to turn them on themselves.
The invention might be subject to many changes and variants, which are all included in the appended claims. Moreover, all the details may furthermore be replaced by other technically equivalent elements, and the materials may be different depending on the needs, without departing from the protection scope of the invention defined by the appended claims.
