Abstract

Vacuum table application system projection printers, comprising a perforated table (2), to through which a vacuum aspiration is applied to fix the pieces (1) to be printed, arranged below the zones perforated table sides (2) limiters (3) that seal vacuum aspiration through areas not covered by the pieces (1), to avoid an influence of the aspiration on the  ink that is projected for printing.

Description

Vacuum table application system projection printers.

Technical sector

The present invention is related to printing processes on rigid or semi-rigid surfaces, by ink spray, proposing an application system vacuum to hold the pieces to be printed on the tables of the printers, so that this vacuum does not influence the ink that It is projected for printing.

State of the art

For printing on rigid surfaces or semi-rigid roller contact technique is known of printing, as well as the technique without contact by means of heads projection, the latter being of greater perfection and quality for the application of the inks.

It is also known to hold the parts intended to be printed on the machine table printers, by means of a vacuum application through the own one table, which can be fixed or formed by a tape conveyor, determining this table with a support surface of the perforated parts, to apply through of her the emptiness of subjection of the pieces.

It happens however that generally the pieces to  print are of a width less than the table surface of support, which in the lateral areas not covered by the piece of application there is a vacuum absorption effect that it can cause the ink to be diverted on the part to print, resulting in imperfections of the print on the piece and the loss of a part of the projected ink.

Object of the invention

According to the invention, a vacuum application system on printer tables, with a provision that cancels the performance of the vacuum in the areas not covered by the piece to be printed, thus avoiding the influence harmful vacuum for printing and ink losses wasted

According to this system of the invention, below of the lateral areas of the surface of the support table of the parts to be printed are provided with shutter limiters of the table perforations, said limiters incorporated in sliding assembly in the transverse direction of the table.

A provision is thus obtained with which the limiters close the vacuum aspiration passage through the lateral areas of the table on which the pieces to be printed support, preventing the effect of such aspiration from having an influence on the ink that is projected to make the impression on the piece ready to be printed.

The mobility of the limiters also allows regulate their position to adjust their placement in relationship with the side areas of the table that are not covered for the piece to be printed in each case, that is to say that it can be adapted the area of action of the vacuum across the table depending on the width of the pieces to be printed, so that the greater fixing force on the table, but without leaks of vacuum that may affect the ink that is projected for Print.

Therefore, said system of the invention results of certain advantageous characteristics, acquiring own life and preferred character for the application function to which is intended in relation to the printer tables that have a vacuum application to fix the pieces to to print.

Description of the figures

Figure 1 schematically shows the system of the invention on a printer table, according to an example of realization.

Detailed description of the invention

The object of the invention relates to a system designed to prevent vacuum losses at tables of inkjet printers, in which the holding of The pieces (1) to be printed are made by vacuum application to through the support table (2) of said parts (1) intended for be printed

The system consists of the provision of limiters (3) as plates, below the surface (4) of transmission of the vacuum to the table (2) provided with perforations (5), on which the pieces are placed ( 1) to be printed, from a chamber (6) to which the vacuum is supplied by a suction system (7), the arrangement being equally valid for fixed tables (2), or for tables (2) formed by a conveyor belt endowed with longitudinal movement
nal.

The limiters (3) are arranged in the assembly with freedom of movement in the transverse direction of the table (2) supporting the pieces (1), so that by said displacement the limiters (3) can be positioned so covering underneath the side parts of the table (2) that do not are covered by the piece (1) arranged on it to be printed.

Thus, the application of vacuum only affects the part of the table (2) covered by the piece (1), achieving a good effect of fixing said piece (1) by the vacuum action, while on the side areas of the table (2) that is not covered by the part (1) no absorption occurs with effect across the table (2), whereby the ink that is project from the heads (8) to make the impression, not it is affected and therefore the conditions of the projection that is applied for the printing of the piece (1).

The movement of the limiters (3), to adjust its position according to the width of the pieces (1) a print, can be done manually, or be equipped with a automatic actuation, without altering the concept of system, which is the sealing of the side areas of the table (2) not covered by the pieces (1) to be printed, so that the absorption of the fixing vacuum of the pieces (1) on the table (2) do not have a detrimental effect on printing.

Claims (2)

1. System of application of vacuum in tables of printers by projection, of the type that comprises a perforated table (2), fixed or mobile, for the support of the pieces (1) to print, with application of a vacuum aspiration through of the table itself (2) for fixing the pieces (1) on it, characterized in that below the side areas of the table (2) there are some limiters (3) in the form of plates that seal the passage of the vacuum aspiration through the areas that the pieces (1) do not cover the table (2).
2. Vacuum application system on projection printer tables, according to the first claim, characterized in that the limiters (3) are arranged in a displacement assembly in transverse direction with respect to the table (2), being able to regulate their placement depending on the width of the pieces (1) to be printed.
