Definitions
- the present invention relates to a squeegee system, provided with a squeegee.
- the invention also relates to a printing unit equipped with a doctor blade system.
- the invention finally relates to a gravure printing machine, incorporating at least one printing unit.
- Photogravure also called rotogravure
- rotogravure is a rotary printing process that can be used for many substrates, including paper or cardboard, using engraved cylinders. Gravure printing is used especially for high-quality editions and large prints where graphics must play an important role in promoting a product, such as a carton pack. This printing process makes it possible in one pass to print up to ten colors, with solvent, water or other inks; to print matt, glossy or structured varnishes; print on front and / or back and emboss.
- a medium to be printed in the form of a continuous strip passes through a succession of gravure printing units.
- the printing units are assembled and arranged one after the other from the input of the print medium upstream to its output downstream.
- Each printing group proceeds to print a pattern with a single specific color or a particular varnish, or even embossing.
- the principle in gravure is to engrave, on the periphery of a printing cylinder, cells that reproduce the pattern that you want to print.
- the engraved cylinder rotated is coated with ink by an applicator and rotates inside a tank containing the ink, which allows to fill the cells.
- the printing medium is then strongly applied against the engraved cylinder, so that the ink contained in the cells can be extracted and transferred onto the medium to be printed.
- a traditional printing group comprises: a printer carriage, itself presenting: an engraved cylinder, an ink applicator, which pours ink on the cylinder, an ink tray, which recovers the overflow of ink, and a squeegee system, which eliminates excess ink on the cylinder by means of scraping blade, leveling the peripheral surface of the cylinder and leaving only the ink that has penetrated into the cells; a pressure roller, which strongly presses the support to be printed on the cylinder; a pump, which conveys the ink from the reservoir to the ink applicator; and - a dryer, which ensures the rapid evaporation of solvents or water, or the polymerization of UV inks.
- the squeegee system provides a constant print quality, ensuring control of the amount of ink contained in the cells.
- the blade is brought into contact with the surface of the cylinder at a line immediately preceding, following the direction of rotation of the cylinder, the zone in which the cylinder comes to contact the medium to be printed.
- the blade is subjected to a movement back and forth on the surface of the cylinder, in the direction parallel to the axis of revolution of the cylinder.
- the angle formed by the plane of the blade with the surface of the cylinder also known as the angle of attack, is important to avoid vibrations of the blade or to prevent ink streaks.
- the contact pressure of the blade on the cylinder must also be adjusted, to allow the contact surface of the edge of the blade against the cylinder, as well as the angle of attack, to remain constant.
- the cylinder for gravure printing has dimensions and a very large weight which cause, on the one hand, transport difficulties, and on the other hand, positioning difficulties.
- the cylinder-tank group is removed by the removable printer carriage, which facilitates its handling and permutation, as described for example in document FR-2.539.325.
- the removable printer carriage which facilitates its handling and permutation, as described for example in document FR-2.539.325.
- the cylinder-tank group is removed by the removable printer carriage, which facilitates its handling and permutation, as described for example in document FR-2.539.325.
- STATE OF THE ART DE-38.41.116 discloses a device intended to be used in gravure printing which comprises a blade holder provided with a blade. Means for balancing the pressure of the blade are provided and incorporate two lateral support rods on each of which is embedded a spring, coming to rest against the doctor blade support, and adjusting elements of the hardness of the springs.
- the squeegee support, and thus the squeegee are also provided for pivoting, with respect to a central axis, passing through the squeegee support and perpendicular to the plane formed by the blade. A shaving of the printing surface is achieved with minimal wear of the blade, the squeegee pressure remaining guaranteed at all points along the squeegee.
- EP-0,765,745 discloses a cleaning device, used in gravure printing, which comprises a doctor blade that can follow the movement of a cleaning roller by means of a cam link mechanism.
- a carrier is secured with pins passing through elongated holes.
- a hydraulic cylinder is attached to the carrier, and an actuating portion of the hydraulic cylinder is connected to the doctor support. By actuation of the hydraulic cylinder, the squeegee carrier moves relative to the carrier, with elongated lumens, allowing the doctor blade holder to move forward and backward with respect to the roller independently.
- the connecting mechanism to follow the movement of the cleaning roller is essential to ensure that the blade comes touching the surface to be wiped. Since this linking mechanism is linked together Laterally with respect to the cylinder and the hydraulic cylinder is attached laterally to the carrier, the contact between the doctor blade and the surface will be very localized at a single point. In addition, the elongated lights limit the movements of the doctor blade support.
- EP-0,422,344 discloses a doctor blade device for use with a platen roller for gravure printing.
- the scraper device comprises a blade, a scraper holder mounted on journals, which are pivotable relative to corresponding lower parts.
- the lower parts, the squeegee holder and thus the squeegee move back and forth along the cylinder.
- the lower parts slide in guides towards the cylinder.
- Air pistons are mechanically connected and press directly on the doctor blade support, so as to slide the lower parts, the doctor blade holder and thus the blade, against the cylinder.
- the pistons provide a constant pressure, but only when a portion of the blade comes into contact with the peripheral surface of the cylinder.
- the presence of the trunnions for pivoting causes the thrust of the pistons against the squeegee carrier causes rotational movements of rotation.
- the back and forth movement also drives each of the pistons.
- a major problem to be solved by the invention is the development of a doctor blade system for optimal scraping of a peripheral surface of the cylinder.
- a second problem is to achieve a squeegee system allowing both a back and forth movement of the blade and an optimal efficiency of scraping the cylinder with the same blade.
- a third problem is that of providing a squeegee system remaining permanently in a printing unit, while ensuring its perfect adaptation to each new cylinder.
- a fourth problem is to use a squeegee system that is independent of the printer carriage and therefore the cylinder, with several possibilities of adjustment of the squeegee system relative to the cylinder.
- a fifth problem is to obtain a squeegee system for a printing group, which is both simple and inexpensive to produce. Still another problem is to mount a squeegee system in a gravure printing machine printing unit to provide high print quality.
- the invention therefore relates to a squeegee system, intended for a printing unit, of the type comprising:
- a doctor blade support provided with a blade, an edge of the blade being able to come into contact with a peripheral surface of an engraved cylinder; a carrier hub on which the doctor blade support is mounted;
- the doctor blade system is characterized in that: the means for reciprocating the blade directly drive the blade holder provided with the blade, and
- the pushing element or elements rest on the structure and move the carrier hub and the blade holder provided with the blade, so as to maintain a constant contact along the entire length of the edge of the blade with the peripheral surface of the engraved cylinder.
- the blade of the squeegee system will touch and remain constantly in contact with the cylinder, regardless of the angular positioning of the latter relative to the blade.
- its straight edge can land on the peripheral surface and remain in abutment along its length, during the complete rotation of the cylinder. If the cylinder has surface defects, wear or mounting inaccuracies, the means present on the squeegee system compensate for the differences, regular or variable, existing or occurring when the cylinder performs a revolution.
- the fine adjustments of the pressure exerted by the edge of the blade on the peripheral surface of the cylinder are not ensured by the thrust element or elements.
- the goal is to maintain a linear contact of the edge of the blade on the surface rotating cylinder device. Such contact will be obtained with each change of cylinder, when new work is requested.
- the back and forth means are used to prevent localized wear too fast blade, detrimental to the quality of printing.
- the doctor blade system thus combines for the blade an ability to move freely, until it enters and remains in constant contact with the surface of the cylinder, and an ability to go back and forth at that surface. of this cylinder.
- the means for ensuring a movement back and forth of the blade only move the doctor blade holder and blade, without the pushing elements, which results in a lightening of fast moving parts.
- the thrust element or elements can generate thrust forces that can be exerted on the carrier hub. These forces can be oriented in the plane defined by the blade.
- the doctor blade system may comprise two thrust elements, which may advantageously be in the form of two springs. These means of applying the thrust to maintain the contact are elastic. These two springs can be arranged laterally, on both sides of the carrier hub, so as to push each side of the carrier hub, towards the peripheral surface of the engraved cylinder.
- the system may comprise means for compensating a torque induced by the movement of the back and forth of the blade. The torque is induced by the additional degree of freedom imparted to the hub carrier, squeegee support and blade, associated with the reciprocating movement of the doctor carrier and the blade.
- the means for compensating the torque may comprise a washer, mounted at one end of an axis of rotation of the carrier hub. This axis of rotation allows the adjustment of an angle between the blade and the peripheral surface of the engraved cylinder and constitutes a point of attachment of the carrier hub with the structure.
- the means for reciprocating the blade may include a pulse finger projecting from the doctor support. This finger can come into contact with pulse means for the back and forth, which are motorized and independent of the doctor blade system.
- the means for reciprocating the blade may comprise a return spring, positioned between the doctor support and the carrier hub, and providing a free return of the blade. squeegee support, after impulse.
- a printing unit is characterized in that it is equipped with a doctor blade system having one or more of the technical features described above.
