Abstract

The invention relates to serigraphic machines for printing on any kind of flat stock. It comprises a sheet conveying system composed of two horizontal rails (R1/R2) all in one piece and two suction bars (B1/B2) sliding vertically to give precision in the conveying of sheets from the position (PM) to the position (PI). The bars (B1/B2) slide vertically downwards in order to take the sheets by depression. An alternative mounting of the ejection bar may consist of mounting this ejection bar (B2) so that it is pointing upwards in order to take the sheets by their underside. <IMAGE>

Description

La présente invention concerne les machines pour impression en sérigraphie sur des objets ou des feuilles de papier ou d'autres matériaux .The present invention relates to machines for screen printing on objects or sheets of paper or other materials.

Dans les machines existant actuellement, la feuille à imprimer est transportée vers le posted'impression par des systèmes à pinces, ou sur une table qui fait elle même le mouvement de va et vient, ou en l'absence de mécanisation placé manuellement, créant ainsi des contraintes de coûts de fabrication ou des pertes de productivité .In currently existing machines, the sheet to be printed is transported to the printing station by clamp systems, or on a table which does the same movement back and forth, or in the absence of mechanization placed manually, thus creating manufacturing cost constraints or productivity losses.

Dans l'invention décrite, le transport de la feuille F fig 1/4 se fait par un train de ventouses qui prend la feuille après que celle-çi ait été placé manuellement sur un poste de pré-marge PM indépendant du poste d'impression .In the invention described, the transport of the sheet F fig 1/4 is done by a train of suction cups which takes the sheet after it has been placed manually on a pre-margin station PM independent of the printing station .

Cette solution permet de diminuer les coûts de fabrication élevés sur les machines à pinces et d'augmenter les cadences de travail des machines à mouvement de table .This solution makes it possible to reduce the high manufacturing costs on gripper machines and to increase the working rates of machines with table movement.

La figure 1/4 représente une vue d'ensemble du système de transport des feuilles, figurant ici un chargement manuel du poste de pré-marge, ce poste pouvant être remplacé par un dépileur automatique de type de ceux déjà utilisés dans les métiers des arts graphiques. Dans cette option le poste de pré-marge PM est doté de courroies de transport .Figure 1/4 shows an overview of the sheet transport system, shown here manual loading of the pre-margin station, this station can be replaced by an automatic destacker of the type already used in the arts graphics. In this option the PM pre-margin station is equipped with conveyor belts.

La feuille à imprimer F est placée contre des butées de repérage, dès l'impulsion de démarrage du cycle, la feuille est aspirée par les ventouses existant sur la barre horizontale B, cette barre coulisse alors sur les rails R1/R2, et place la feuille sur le poste d'impression PI après que sa vitesse eut été réduite et que la barre B1 vienne en butée sur P, à ce moment précis l'aspiration des ventouses est supprimée et la feuille est plaquée par l'aspiration de la table T qui fait partie du poste d'impression PI. Le train de ventouses B1 revient alors à sa position initiale et le chassis porte écrans A descend en position d'impression . Fig 3/4The sheet to be printed F is placed against locating stops, as soon as the cycle start impulse, the sheet is sucked up by the suction cups existing on the horizontal bar B, this bar then slides on the rails R1 / R2, and places the sheet on the printing station PI after its speed has been reduced and the bar B1 abuts on P, at this precise moment the suction of the suction cups is removed and the sheet is pressed by the suction of the table T which is part of the PI printing station. The suction cup train B1 then returns to its initial position and the screen holder chassis A descends to the printing position. Fig 3/4

Lorsque la phase d'impression est achevée le train de ventouses B2 exécute un court mouvement en arrière, vient en butée sur P, les ventouses aspirent la feuille qui vient d'être imprimée et effectuent un mouvement de dégagement afin de déposer la feuille imprimée sur les courroies C qui vont assurer le dégagement de celle-çi vers le tunnel de séchage .When the printing phase is completed, the suction cup train B2 performs a short backward movement, abuts on P, the suction cups suck up the sheet which has just been printed and carry out a releasing movement in order to deposit the printed sheet on the belts C which will ensure the release of this one towards the drying tunnel.

La figure 2/4 représente une vue en coupe frontale .Figure 2/4 shows a front section view.

Ce type d'équipements peut-être utilisé dans des domaines très variés tels que l'impression d'affiches en grand ou petit format et tous les travaux d'impression sur tôles, bois, textiles, supports adhésifs, etc...This type of equipment can be used in a wide variety of fields such as large or small format poster printing and all printing work on sheets, wood, textiles, adhesive media, etc.

Claims (4)
