Description

SCREEN PRINTING METHOD AND MACHINE
The present invention relates to a screen printing method and machine . The known screen printing machines are endowed with a printing head, which is supported by two couple of columns that allow the printing head to be lifted and lowered.
The two couples of columns are in turn lifted and lowered by chains, driven by a first motor, which is linked to them.
In this way, it is possible to move said printing head in a direction parallel to a printing plane, in order to allow pinches and/or the above-mentioned plane to be moved and load the sheet to be screen-printed.
Said printing head is then parallel to the printing plane and can be moved in a direction orthogonal to it by the first motor.
The printing head is also linked to a bearer structure, which is able to support the printing frame while, at the same time, inclining the above-mentioned printing frame with respect to the printing plane.
In this way, it is possible to lift the fabric on the printing frame from its support . During this operation, the printing frame is gradually inclined with respect to the printing plane, on which the sheet to be screen-printed is placed. At the same time, the coating blade is made to slide on the printing frame, so as to distribute the ink, or inks that were previously placed on the printing frame. The inks spread on the mails of the printing frame and consequently on its openings, obtained through photographic techniques and directly exposed on the sheet to be screen-printed.
In this way, at the end of the printing operations a uniform ink layer is deposited on the parts of the sheet that have been exposed to the printing frame mails . The bearer structure, then, includes inclination means, aimed at allowing screen printing without ink overflowing and stickiness, due to its viscosity, a process called "peel off" . Said inclination means include a second motor, which is linked to an extremity of the printing frame and allows its inclination with respect to the printing head and, consequently, to the printing plane.
Moreover, said inclination means include an actuator, aimed at bringing the frame back to a position parallel to the printing plane. This allows the following operation, in which a blade is made to slide on the printing frame, so as to deposit more ink on the mails of the fabric, which is fixed to the frame, for the following screen-printing operation.
This operation must be performed with the frame parallel to the printing plane, in order to obtain a homogeneous layer of ink on all the frame surface. A disadvantages of the known screen-printing machines is that they are complex and costly devices, mainly due to their large number of components .
A disadvantage of the known screen-printing machines is the fact that the inclination means of the bearer structure do not allow immediate return of the blade, with the consequent waste of time and screen printing machine yield reduction.
In fact, the bearer structure has to be lowered by repositioning it parallel to the base plane and then the printing head has to be lifted before the ink spreading phase, when the blade goes back to its initial printing position.
A further disadvantage is that the inclination means include at least an actuator, such as for example a piston, which allows the bearer structure to be lowered, with the consequent repositioning of the printing frame parallel to the printing plane. The aim of the present invention is to realise a screen printing method and machine that allow a printing time reduction.
A further aim is to have a screen printing method and machine that allow a yield increase.
A further aim is to have a screen-printing method that is both simple and includes a reduced number of phases.
A further aim is to have a cheap screen-printing machine with a simple structure. These aims, according to the present invention, are achieved by realizing a screen-printing method and machine as exposed in claim 1.
Further characteristics of the present invention are exposed in the following claims . The features and advantages of a screen-printing method and machine, according to the present invention, shall become clearer from the following description, given as an example and not for limiting purposes, referring to the attached drawings, in which: figure 1 is a lateral left view from the above of a preferred realisation form of a screen-printing machine, according to the present invention; figure 2 is a lateral left view of the machine in figure 1, which also shows a first phase of a preferred form of realisation of a screen-printing method, according to the present invention; figure 3 is a lateral left view of the machine in figure 1, which shows a second phase of a preferred form of realisation of a screen-printing method, according to the present invention; figure 4 is a lateral left view of the machine in figure 1, which shows a third phase of a preferred form of realisation of a screen-printing method, according to the present invention; figure 5 is a lateral left view of the machine in figure 1, which shows a fourth phase of a preferred form of realisation of a screen-printing method, according to the present invention; figure 6 is a lateral left view of the machine in figure 1, which shows a fifth phase of a preferred form of realisation of a screen-printing method, according to the present invention.
With reference to these figures, a screen-printing machine (10) is shown, including a printing head (20) , a printing frame (32) and a printing frame (33) . Said printing head (20) is supported through a first couple (12) of columns and a second couple (14) of columns that can be lifted or lowered with respect to the printing plane (33) . Said screen-printing machine (10) includes said first couple of columns (12) , adjacent to each other, and a bearer structure (30) , which is fixed to said printing head (20) .
Moreover, said machine (10) includes a first motor (41) and a second motor (42) , driven independently from each other, which are respectively linked to the first couple of columns (12) and the second couple of columns (14) .
This has the aim of inclining said printing frame (32) with respect to said printing plane (33) , by lifting or lowering the first couple of columns (12) in an independent way from the second couple of columns (14) . Consequently, since said bearer structure (30) is fixed to said printing head (20) , by inclining said printing head (20) , said bearer structure (30) is inclined, as well.
Said machine (10) also includes at least a sliding joint (52) that links each column of said first couple of columns (12) to said printing head (20) . Said machine (10) also includes at least a sliding joint (51) that links each column of said second couple of columns (14) to said printing head (20) . In other words, at least one of the sliding joints (52) is essentially a joint that allows complete rotation with respect to a horizontal axis while, at the same time, being engaged with a corresponding slit (56) , which allows it to slide in a horizontal direction. Moreover, said machine (10) includes a plurality of guides (54) , housed on said printing head (20) , each one of which is respectively linked to a printing cart
(26) , which is in turn linked to said printing head (20) through said guides (54) , in order to allow said printing cart (26) to slide along a direction parallel to said printing head (20) .
Said machine (10) includes said printing cart (20) , which in turn includes a coating blade (27) and a blade (28) , which can be either lifted or lowered independently from each other in a vertical direction, through the action of the corresponding actuators linked to them (not shown here) . Alternatively, these can be lifted and lowered with a rotational motion with respect to their support bar.
In other words, said printing frame (12) is linked to the first and second couples of columns (13) and (14) through a plurality of sliding joints (52) and a plurality of joints (51) , in order to incline it with respect to said printing plane (33) .
Moreover, said printing plane (33) is linked to elements (17) , which are inserted in, and supported by, support portions (15) , essentially in the shape of a flange, of said plurality of first columns (12) and said plurality of second columns (14) . In particular, said support portions (15) are each one fixed to a corresponding fixed part of each column of said first couple of columns (12) or said second couple of columns (14), as shown in the figures. In this way, it is possible to get said printing frame (32) near to said printing plane (33) , simply by lifting or lowering at the same time said first couple of columns (12) and said second couple of columns (14) . This is due to the fact that said printing frame (32) is fixed to said printing head (20) and, moreover, both are in turn fixed, through the plurality of sliding joints (52) and the plurality of joints (51) , to said first couple of columns (12) and said couple of columns (14) . In particular, each sliding joint (52) is positioned on a corresponding moving part, preferably near the free extremity, of each column of said first couple of columns (12) . In particular, each joint (51) is positioned on a corresponding moving part, preferably near the free extremity, of each column of said second couple of columns (14) .
In this way, it is possible to incline said printing head (20) and said printing frame (32) with respect to said printing plane (33), simply by turning on a motor only, namely by turning on the first motor (41) or the second motor (42) .
In an equally simple way, it is also possible to translate said printing head (20) and said printing frame (32) in a vertical direction, parallel to the printing plane (33) , by turning on the first motor (41) and the second motor (42) at the same time. This has the aim of putting said printing frame (32) in contact with said printing plane (33) or taking it away from such plane before a new screen-printing operation takes place.
Advantageously, since said printing frame (32) is directly linked to said printing head (20) , there is no need of means for registering the position of said printing frame (20) with respect to said printing head (20) , such means being usually employed in the known screen-printing machines .
According to another aspect of the present invention, a preferred form of realisation of a screen-printing method is supplied, such method making use of a screen- printing machine, including a printing head (20) , a printing plane (33) , a printing cart (26) , endowed with a coating blade (27) and a blade (28) , and a bearer structure (30) , including a printing frame (32) and linked to a first couple of columns (12) and a second couple of columns (14) . Said screen-printing method, shown in particular in figures 2 to 6, includes the phases of: a) loading a sheet to be screen-printed on said printing plane (33) ; b) printing said sheet by progressively inclining said printing frame (32) , with respect to said printing plane (33) ; c) coating the mails of said printing frame (32) with ink. Said phase b) preferably includes the acts of lowering the printing head (20) and the printing frame (32) by getting the printing frame (32) as near as possible to the sheet supported by the printing plane (33) .
Said method includes the subsequent operation of lowering said coating blade (27) , so as to touch said printing frame (32) .
Said method includes the subsequent operation of moving said printing cart (26) along said guides (54) , from a printing start position to a printing end position, so as to push said coating blade (27) and make it slide on said printing frame (32) .
This has the aim of uniformly distributing the ink on said printing frame (32) , in particular on the portions of said printing frame that are directly exposed to the sheet to be screen-printed. Preferably, said phase b) includes the phase e) of progressively lifting said first couple of columns
(12) , so as to progressively incline said printing frame (32) during the movement of said coating blade (32) , from a printing start position to a printing end position.
At the end of phase b) and before said phase c) , said method includes the action of bringing said printing frame (32) back to a position parallel to said printing plane (33) while, at the same time, moving it to a disengagement position above said printing plane (33) . In other words, this preferably happens by rotating said printing frame (32) , which has four extremities, with respect to an axis including two such extremities, adjacent to each other and placed in a higher position than the two remaining extremities .
According to a preferred form of realisation, said phase d) preferably includes the phase of lifting said second couple of columns (14) to the same height as said first couple of columns (12) , as shown in figure 5.
With this simple operation, the bearer structure (30) is placed parallel to said printing plane (33) and, at the same time, is lifted together with said printing head (20) . In this way, the screen-printing procedure is advantageously and substantially simplified since, with the known state of the art, the same result was achieved with two subsequent phases, while it is now achieved with one only phase.
Said phase c) preferably includes the operations of lowering said blade (28) , so that it gets in touch with said printing frame (32) and said blade (28) slides on the surface of said printing frame (32) , from a position near the printing end position to a position near the printing start position.
This has the aim of coating the mails of the printing frame (32) with ink, before loading a new sheet for a subsequent screen-printing operation. It has then been shown that a screen-printing method and machine according to the present invention realise the above-mentioned purposes.
The screen-printing method and machine according to the present invention are susceptible to numerous modifications and variants, all covered by the present invention.
In practice, the employed materials, as well as their dimensions and the employed components can be whatever, according to the technical requirements .
