Abstract
A process and device for silk-screening flat objects, in particular ceramic tiles
(2), in which a rotary cylindrical silk screen (3) is made to pass between a
doctor (4) and a contrast element (5) made of teflon. Glaze is distributed on the
doctor (4), which glaze is forced by action of the doctor (4) and the contrast
element (5) to occupy perforations in the silk screen (3). A blower (6), internal
of the silk screen (3) and operating on a bottom generatrix thereof, directs a jet
of air downwards, so that the glaze contained in the screen perforations is
blown by the jet and transferred on to the upper surface of the tiles (2). The
invention considerably reduces wear on the silk screen (3).
Description
- Specifically, though not exclusively, the invention can be used for making silk screen designs on flat objects, especially ceramic tiles.
- The prior art teaches silk screening processes on ceramic tiles, where the screen is rotary and mounted on a cylinder. In these applications the silk screen is set in rotation about a horizontal axis and made to roll without dragging on underlying tiles transiting along a conveyor line. The screen is constituted by a net-type screen supported on a structure which makes the screen cylindrical.
- The liquid product to be distributed on the tiles, constituted by one or more ceramic glazes, is introduced internally of the screen, where a doctor, operating on the bottom generatrix of the screen, causes the glaze to pass through the spaces in the screen.
- This process exhibits some drawbacks.
- Firstly, contact between the tiles and the silk screen causes rapid screen wear, which means frequent screen substitution.
- Secondly, due to the screen action, the tiles can be subjected to flexion, especially if the screening is done in more than one stage. This can lead to serious risk of damage to the tiles.
- A further drawback is that in order to perform a correct silk screening process, the surface of the tiles must be completely smooth and flat; as a consequence traditional silk screening is not suited to tiles having a corrugated top surface, or a surface featuring reliefs.
- The main aim of the present invention is to obviate the above-mentioned drawbacks by provided a silk-screening process which considerably reduces wear on the silk screen.
- An advantage of the invention is that it eliminates risks of damage to the objects undergoing silk screening due to the action of the screen and the doctor on the objects themselves.
- A further advantage is that corrugated or otherwise non-flat surfaces can be silk-screened using the process.
- A further aim of the invention is to provide a device, constructionally simple and economical, which can be used to realise the process of the invention.
- These aims and advantages and others besides are all attained by the present invention, as it is characterised in the appended claims.
- Further characteristics and advantages of the invention will better emerge from the detailed description that follows of some preferred but non-exclusive embodiments thereof, illustrated purely by way of non-limiting example in the accompanying figures of the drawings, in which:
- figure 1 schematically shows a side view in vertical elevation of a first embodiment of the device of the invention;
- figure 2 schematically shows a side view in vertical elevation of a second embodiment of the invention;
- figure 3 schematically shows a side view in vertical elevation of a third embodiment of the invention.
-
- With reference to figure 1, 1 denotes in its entirety a device for silk-screening objects, advantageously utilsable in particular for silk-screening flat objects, such as
ceramic tiles 2. - The silk-screening device 1 is predisposed above a transport line along which the
tiles 2 can advance in ordered succession in an advancement direction indicated by arrow F. - The silk-screening device 1 comprises a
silk screen 3, the screen itself being made of a net material having perforations through which a glaze to be applied on an upper surface of the underlying tiles can pass. - In the embodiment of figure 1, the
screen 3 is cylindrical with an axis extending transversally of the tile advancement direction F. Thescreen 3 can be set in rotation about the axis, in coordination with the tile advancement motion, by means of a motor which is of known type and not illustrated. - The lower tract of the
screen 3, constituted in the example by its bottom generatrix, is mobile in a parallel direction to tile advancement direction F, and is located at a short distance from, but not touching, the underlying upper surface of thetiles 2 transiting along the transport line, without interacting with the tile surfaces. - Means are provided on the
screen 3 in a zone upstream of the bottom generatrix of the screen (by upstream we mean in reference to the rotation direction of the screen 3), which means are for filling the perforations in the screen with glaze. The means for filling comprise a fixed doctor 4 predisposed to operate on the internal surface of thescreen 3; set in opposition to thescreen 3, on the outside of the cylinder, is arigid contrast element 5 having a constrasting surface which can operate in contact with the outside surface of thescreen 3. During operation thescreen 3 is made to rotate contactingly between the doctor 4 and thecontrast element 5, and exhibits a curvature which corresponds to the curvature of the screen drum. The contrast surface is preferably made of a low-friction material, such as teflon. - The device 1 is also provided with known-type means (not illustrated) for distributing the glaze internally of the
screen 3 in the zone comprised between the doctor 4 and the internal surface of thescreen 3. - Blowing means are positioned above the bottom generatrix of the
screen 3, which means direct a jet of air downwards so as to strike the upper surface of the underlying and transitingtiles 2, through the perforations in thesilk screen 3. Theblower 6 is constituted by a pneumatic convector provided with a jet for expelling air downwards, which jet is elongate and narrow so as to interest the whole of the bottom generatrix of the screen drum. Thus the jet of air is concentrated on the generatrix, i.e. a narrow and long zone of the mobile bottom tract of thescreen 3 and parallel to the longitudinal axis of thescreen 3. - During operation, the
tiles 2 are fed in succession along the transport line, while thescreen 3 is set in rotation in the direction denoted by arrow G, so that the drum's peripheral speed coincides with that of the advancement of the tiles. - The glaze is distributed on the doctor 4 which, cooperating with the surface of the
contrast element 5 contrasting it, squeezes the glaze into the perforations in thescreen 3. The doctor 4 operates so as to scrape the excess glaze and to clean the full zones of the screen, leaving them substantially free of glaze. - When the screen is rotated and the glaze contained in the empty perforations in the
screen 3 passes under theblower 6, the jet of air issued drags the glaze with it and deposits it on the underlying and transitingtiles 2. The whole process, it is stressed, is continuous. - Figure 2 is an illustration of a further embodiment of the invention, where the doctor 4 operates on the external surface of the
screen 3, while the active surface of thecontrast element 5 operates on the internal surface of thescreen 3. The doctor 4 is located in the upper half of thecylindrical screen 3, whereas in figure 1 it was located in the bottom half. The glaze is distributed between the doctor 4 and the external surface of thescreen 3. Apart from this, the structural elements and the operation of the screen are substantially the same as in the first embodiment shown in figure 1. In figures 1 and 2 the same contructional elements are denoted with the same numbers. - In the embodiment of figure 3, the screen, though having like the other embodiments a tubular form with a longitudinal axis arranged transversally to the advancement direction F of the
tiles 2, is not cylindrical, but is made of flexible tape ring-wound aboutwheels 7 so that it can be drawn in movement about thewheels 7 themselves about a longitudinal axis thereof in the direction indicated by arrow D. A brief inferior tract of thescreen 3 is maintained in tension by means of two wheels situated side-by-side, in a flat, horizontal and parallel arrangement in relation to the upper surface of the transiting underlyingtiles 2. Theblower 6 operates at the lower, flat tract of thescreen 3. In this case too the filling of the screen matrix with glaze is done by a doctor 4 and acontrast element 5 counterposed thereto. The active surface of thecontrast element 5, which imitates the form of thescreen 3, is substantially flat and acts at an oblique tract of thescreen 3. The doctor 4 operates internally of thescreen 3, upstream of theblower 6 where theglaze 6 is distributed to fill the matrix. In this case too the glaze contained in the matrix of the screen is then struck by the air jet issued from theblower 6 and projected on to the upper surface of thetiles 2. The operation of the device of figure is substantially the same as in the other two embodiments. - In a further embodiment, not illustrated, during the application of the glaze on the tiles, the tiles themselves and the screen, with the matrix loaded with glaze, are immobile while the blower is horizontally mobile on the screen, which in this embodiment can be flat. The loading of the glaze in the screen perforations can be achieved, like in the previous embodiments, by a filler device which is mobile with respect to the screen, comprising a doctor and a counter-doctor, between which the screen is made to pass before being positioned on the waiting tile.
- In all of the above-described embodiments, the screen is never in contact with the upper surface of the tiles. The transfer of the glaze on to the tile is done by means of an air jet which passes through the matrix of the screen and transfers the glaze from the matrix on to the underlying tiles. The screen is subject only to a contact drag with the doctor contrast element, which can be made of an anti-friction material, with a subsequent considerable reduction in screen wear.
- During operation, the silk-screening devices actuate a process for silk-screening flat objects, in particular
ceramic tiles 2, in which the matrix of a silk-screen 3 made of a net material with perforations, is filled with glaze and then neared into a non-contacting facing position to the upper surface of thetile 2 to be glazed. - The loading of the perforations of the matrix with glaze by making the
screen 3 pass contactingly between a doctor 4 and a low-friction contrast surface, and distributing the glaze on the doctor 4 which, in cooperation with the contrast surface opposing it, forces the glaze into the matrix perforations. - When at least one zone of the matrix, loaded with glaze, is arranged facing the
tile 2, an air jet continuously strikes the glaze in that matrix zone. The jet is directed against thetiles 2, so that the glaze in drawn by the air jet and transferred on to the surface of thetile 2, while thescreen 3 is kept at a brief distance (but without touching) from the surface. The air jet should preferably be concentrated in a restricted zone of thescreen 3 and extended in a transversal direction to the advancement direction F of the screen itself and thetiles 2.
