Definitions
- the object of this Patent Invention is a device for the silk screening onto pottery articles that incorporates significant innovations and advantages compared to the present devices and systems used for the same purpose.
- the new invention consists of a device for the silk screen printing onto pottery items or materials having similar properties, and particularly, the front surface with a relief or curved surfaces that have a bed on which the pottery pieces are moved, a means of injecting the paint or dye onto the front surface and a template or screen that outlines the painted shapes onto said front surface.
- the silk screen printing process for pottery items is carried out by means of making contact between the parts by two spatulas or similar devices activated hydraulically in which by the inertia of the process chain, one of the spatulas spreads the paint onto the template on which there is a decoration determined by the drawing on the surface of the template, meanwhile the other spatula transfers the dye onto the part and removes the excess paint.
- the surface of the pieces must be flat so that the spatulas spread the paint in a homogeneous way over the whole surface.
- the present invention has been developed for the purpose of providing a device for the silk screen printing of pottery items that finds a solution to the previously mentioned disadvantages, in addition providing other additional advantages that will be clear from the description that is attached below.
- the device for the silk screen printing onto pottery items of the present invention in particular, with the front surface with a relief that has a bed on which the pottery pieces are moved, a means of injecting the paint or dye onto the front surface and a template or screen that outlines the painted shapes onto said front surface by means of lines or connecting points, and is characterised by the fact that in addition it includes a means for the creation of an air flow curtain under pressure that is arranged noticeably vertical and above the template or screen, without there being any physical contact between the front surface of the pottery item and any other element of the device, using said air curtain to transfer the ink from the template to the pottery item.
- an easily constructed device that allows the automation of the silk screening process for pottery items with relief, for example, decorative types, or roman or curved pieces, in such a way that the production costs and the number of employees necessary are reduced as the device can be installed on a production line for the pottery items or other materials having similar characteristics.
- the type of silk screening obtained has the same degree of quality as that obtained for flat pieces.
- the machine also has spatulas to spread the paint or dye onto the template and to eliminate the excess paint or dye remaining.
- the machine can silk screen items with or without a relief patterns without having to have two production lines for each type of piece.
- there are two spatulas so that painting can be carried out in two directions.
- An advantage is to have a means of regulating the air flow and the size of the curtain. In this way the air flow curtain can be adapted to different sized pieces to be silk screened.
- said means of regulation would be made up of a multitude of pistons.
- the means of creating the air flow curtain under pressure, the means for regulating the flow rate and the spatulas are arranged on a mobile support.
- the device (1) for the silk screening of pottery items of the present invention can be located on a production line for pottery items or materials having similar characteristics (being by preference prior to the firing stage of the pottery items), it is made up of a base (2) which has a section of conveyor belt or belt guide elements (3) for the item (4) (shown by broken lines) along which the pottery items (4) are moved, a means for the injection of paint or dye of a known type (not shown as it is not the object of the invention) in order to apply the paint onto the front surface of the item (4) and a template or screen (5) (shown by broken lines) that outline the painted shapes on said front side.
- the stated device (1) additionally has some means for the creation of an air flow curtain under pressure (6) arranged in an appreciably vertical manner and above the template or screen (5), without there being any physical contact of the front surface of the pottery item (4) with any other element of the device being necessary in order to carry out the silk screening.
- the flow of air is provided by means of a tube (10) connected at one end to an air supply source whilst the other end is fixed to a platform (11) that releases said air flow curtain.
- the device (1) is also made up of at least one conventional type spatula (7) to spread the paint or dye onto the template (5).
- the device (1) for the silk screening object of the invention also comprises of some means of regulation for the air flow and the size of the curtain, said means being a multitude of pistons (12) arranged in such a way as to make a rectangular shape.
- the assembly formed by the spatulas and also the means for creating of the flow curtain (6) are situated on a support (8) that is moveable in a perpendicular direction to the direction of the movement of the pottery items (4) during the silk screening operation. Said movement is carried out by means of a pair of transfer bars (9) that allow the movement to take place in the direction of the black arrows shown on figure 1.
- FIG. 4 a second embodiment of the device of the invention is shown.
- the main difference in comparison to the first preferred embodiment is the fact that the support (8) moves in the same direction as the pottery item (4) as and how shown by means of the black arrows.
