Description

HOT AIR DEVICE FOR SUBLIMATION OF INK ON SUPPORTS PREVIOUSLY PRINTED BY PRINTING MACHINES, PREFERABLY BY DIGITAL PRINTING MACHINES, AND RELEVANT PRINTING PROCESS
The present invention relates to a hot air device for sublimation of ink on supports previously printed by printing machines, preferably by digital machines, and relevant printing process.
More particularly, the invention refers to the printing field employing sublimatic ink, carried out by printing machines, preferably digital machines, such as plotters, but also employing standard machines.
It is known, that sublimatic ink, after print, i.e. after deposition of the ink on support material (usually fabric), must be subjected to a passage from the solid state to the gaseous state, to be permanently fixed on the same support, said transformation only occurring at high temperatures.
In the traditional machines, available on the market since many years, support material printed with sublimatic ink is passed through a heated roll calender at adjustable speed and temperature: process must be continuously carried out to prevent burning or structural transformation of the support material, usually a synthetic material, that can occur in case of continuous and long contact with the hot surface. It causes the impossibility of feeding the calender directly from the printing machine wherein the support material is advanced stepping.
It is thus necessary winding the printed support material about a roll, which is then taken and placed on the uncoiler integral with calender.
Furthermore, at .present, printing with sublimatic ink occurs only on support materials, particularly fabrics already coupled with a paper support that must be separated before its introduction of the support material in the calender or it is carried out on a special paper and then transferred in calender on the support material.
Object of the present invention is that of realising a device that can be directly mounted on a printing machine employing sublimatic ink and avoiding the technical drawbacks described in the above. Furthermore, the device according to the invention allows printing directly on the support material, without the need of further coupling supports and without requiring winding the finished product about a roll. Further object of the invention is that said device can be realised with quite low costs, both for its manufacturing costs and for its handling and working costs.
Still another object of the present invention is that of providing a device of the above kind allowing carrying out sublimation of ink on each kind of support previously printed by printing machines, preferably by digital printing machines, without modifying the finishing of the same support. For example, the device according to the invention allows sublimation, beside on traditional supports, also on supports as alcantara and velvet.
Last but not least object of the invention is that of realising a device that is simple, safe and reliable.
These and other objects are obtained according to the present invention realising a hot air device for sublimation of inks after print and a printing process employing sublimatic ink.
It is therefore specific object of the present invention a hot air device sublimation of inks after print according to claim 1.
Further features of the device according to the present invention are described in the dependent claims 2 - 16. It is further a second object of the present invention a printing process employing sublimatic ink as claimed in claim 17.
Further features of the device according to the present invention are described in the following claims 18 - 21.
Advantageously, the device according to the present invention allows working the support material without inducing structural transformations, guaranteeing at the same time permanent fixing of ink on the same support material, without remarkable variations during the time.
Furthermore, in case material is a fabric or a porous structure material, hot air jet helps ink, when passing from solid state to gaseous state to deeply penetrate within the support material.
Further features advantages of the hot air device for sublimation of inks after their printing, according to the present invention, will be more evident from the following specification, which is exemplificative and not limitative, referred to the enclosed drawings, wherein: - Figure 1 shows a perspective view of a hot air device for sublimation of inks according to the present invention, provided downward the withdrawal roll of a printing machine;
- Figure 2 shows a perspective view of a particular of the device of figure i;
- Figure 3 shows a lateral schematic view of the device of figure
1 ;
- Figure 4 shows a front schematic view of the device of figure
1 ; - Figure 5 shows a lateral and partially in section schematic view of the air delivering apparatus of the device of figure 1 ;
- Figure 6 shows a front and partially in section schematic view of the air delivering apparatus of the device of figure 1 ; and
- Figure 7 shows a perspective view of a printing machine with the device according to the invention for working strips as support material.
Making reference to the enclosed figures, device according to the invention comprises a carriage 1 , movable along a sphere recycle prismatic guide 2, provided downward the withdrawal roll A of a printing machine with sublimatic ink. Stroke of the carriage 1 movable along the guide 2 is adjusted by a stop 3. Motorisation of movable carriage 1 is obtained by a direct current ratiomotor.
A hot air delivering apparatus 4, or an industrial hot air generator, is provided on the movable carriage 1 , placed inside a housing and provided with a suitable conveying joint 5 and with an ejection nozzle 6. The ejection nozzle 6 has a narrow shape (in the direction parallel to the one of extension of the guide 2) and extended (in the direction transversal to the one of extension of the guide 2). Particularly, in preferred embodiment of the invention, dimensions of hot air emission nozzle 6 are such to ensure an emission width of about 100 mm and an emission depth between 6 mm and 10 mm.
Above the air delivering apparatus 4, all along the guide 2, a abutting hollow hemi-cylinder 7 is provided, shaped in such a way to oppose the cylindrical surface 8 to the air delivering apparatus 4, said surface being comprised of stainless steel sheet. Curvature ray of the cylindrical surface 8 is preferably between 120 mm and 160 mm. Hemi- cylinder 7 is closed at the top by a lid 9, suitably shaped in order to prevent buckling due to the high temperatures, in such a way to create a chamber 10, within which hot air is sent by two blowers 11 , provided at the ends of chamber 10.
In order to maintain as much as possible constant the temperature of the cylindrical surface 8, and in order to limit power consumption of two blowers 11 , within chamber 10 it is also introduced a tank containing thermal oil. Higher thermal inertia of this oil allows reducing the temperature oscillations and deactivating blowers 11 once the desired temperature is reached. Printed support material arriving fro the printing machine is passed in the zone between the hemi-cylinder 7 and the hot air delivering apparatus 4. distance between hemi-cylinder 7 and hot air delivering apparatus 4 is preferably chosen within the range 15 - 30 mm.
A transmission idle roll 12, downward the hemi-cylinder 7, allows maintaining the printed support material always sufficiently tighten to adhere to the cylindrical surface 8 of the hemi-cylinder 7, at the same time maintaining constant the distance between the printed support material and the hot air delivering apparatus 4.
Afterwards, support material is sent, through further transmission means 13, to a winding roll 14.
Device further comprises control means (e.g. a touch screen, not shown) interacting with a programmable control logic unit (not shown) for controlling and setting the different operational parameters.
Operation of the hot air device for sublimation of inks, according to the present invention, is substantially as follows.
Support material arriving from the printing machine, is taken by withdrawal cylinder A and manually passed between hemi-cylinder 7 and hot air delivering apparatus 4 and through transmission rolls 12 and 13, up to the winding roll 14. The stop 3 is then placed to limit the hot air delivering apparatus 4 stroke in function of width of support material subjected to working. In order to prevent that inversion of motion of delivering apparatus can cause too high concentration and too long time of hot air on the working material, stop 3 is placed in such a way that the delivering apparatus 4 stoke goes beyond the ends of the working support material.
Now, hot air temperature and delivering apparatus group translations speed are set. Hot air temperature delivering apparatus group translations speed vary in function of the kind of ink and of support material used, and are strictly correlated each other. Preferably, this pair of parameters takes values varying respectively within the range between 4000C and 6000C, and between 12 and 20 m/min. The device is started.
Movable carriage 1 moves reciprocating from one end to the other one of the path delimited by stop 3, which is adjustable along the guide 2, delivering apparatus 4 continuously sending hot air all along the surface of the printed material and without causing burning or permanent deformations.
It is further allowed the operation of the two hot air blowers 11 within the chamber 10 inside the hollow hemi-cylinder 7, by which the oil contained within the tank of chamber 10 is heated. Thus, it is prevented the cooling of passing support material, increasing its temperature on the surface opposite to the one faced toward the hot air delivering apparatus 4.
In this way, a perfect and deep sublimation print is obtained.
In the embodiment of figure 7, wherein the same reference numbers are used to indicate elements similar to those shown in the previous figures, it is shown the use of the device according to the invention for feeding strip shaped supports, such as bands usually employed for hanging object like keys, phones, etc. on the neck.
In this case, rolls 15, longitudinally distributed along the machine, feed material strips, not shown. The present invention has been described for illustrative but not limitative purposes, according to its preferred embodiments, but it is to be understood that modifications and/or changes can be introduced by those skilled in the art without departing from the relevant scope as defined in the enclosed claims.
