Definitions
- Figs. 1 and 2 show an apparatus for mounting a plate on a plate cylinder according to an embodiment of the present invention.
- Fig. 1 shows the apparatus when viewed from its side
- Fig. 2 partially shows the front left portion of the apparatus.
- a printing unit 1 comprises a pair of right and left frames 2 to cover the side surfaces of the printing unit 1.
- a plate cylinder 3 and a blanket cylinder 4 are arranged in contact with each other inside the frames 2.
- An inking apparatus and a dampening apparatus (neither are shown) for supplying ink and dampening water to the surface of the plate mounted on the plate cylinder 3 are arranged above the plate cylinder 3 and on the side thereof, respectively.
- a pair of right and left L-shaped arms 11 are fixed on the support shaft 9 mounted with the lever 10, so that the arms 11 are set in phase and have a predetermined angle with respect to the lever 10.
- the right and left arms 11 are pivoted through about 90° through the lever 10 and the support shaft 9, as indicated by solid lines and broken lines in Fig. 1, respectively.
- the arms 11 located at positions indicated by the solid lines are close to the horizontal surfaces 2a and vertical surfaces 2b of the right and left frames 2.
- the lower end portions of the right and left arms 11 are connected by a cover support shaft 12.
- Right and left vertical bars 14 constituting a safety cover 13 are pivotally supported at the two end portions of the cover support shaft 12.
- Fig. 3 shows a developed state of a plate in a state wherein reference pins are fitted in reference notches, respectively.
- two reference notches 32 are formed at a leading-side end portion 241 of the plate 24.
- the U-shaped reference notches 32 are open to the edges of the plate so that they are perfectly engaged with the reference pins 31, respectively.
- the support shaft 9 is pivoted through the lever 10, so that the right and left arms 11 supported by the support shaft 9 are pivoted to the positions indicated by the broken (chain and double-dotted) lines.
- the safety cover 13 having the vertical bars 14, the upper end portions of which are pivotally supported by the lower end portions of the arms 11, is moved to the position indicated by the broken lines while the plate is kept held as indicated by reference numeral 24A.
- a portion in front of the plate cylinder 3 is open.
- the pins 16 are linearly lifted along the longitudinal axis of the guide bars 17, so that the safety cover 13 is bent in an L shape at the position indicated by the broken lines.
- the plate press member 26 is exemplified as a plate holding member for pressing the plate downward while the upper end portion of the plate is inserted in the plate lockup device.
- the plate holding member is not limited to this.
- trailing-side end portion of a plate can be clamped by suction pads, rollers, or the like.
- the plate holding member for holding the plate so as to urge it downward is arranged in the vertically openable safety cover, the upper end portion of which is supported by a printing press member so that the safety cover is suspended from the printing press member, the recesses formed at the lower end of the plate can be accurately urged against and engaged with the reference pins of the plate lockup device by the weight of the plate and the behavior of the plate holding member.
- Mounting precision of the plate can be improved, and printing alignment precision can be improved accordingly.
- the alignment adjustment time can be almost eliminated to shorten the plate mounting time, thereby improving operation efficiency of the printing press and reducing the waste paper.
- the plate can be easily mounted without specific skill, thereby achieving energy saving.

- Appareil pour le montage d'une plaque sur un cylindre porte-plaque d'une presse à imprimer, comprenant des moyens (28) de fixation de plaque disposés sur ledit cylindre porte-plaque (3) pour recevoir et maintenir une extrémité d'attaque de la plaque,un élément support couplé à ladite presse à imprimer (2) et un couvercle de sécurité (13) supporté par ledit élément support et suspendu à partir de lui pour s'ouvrir verticalement et se refermer afin de recouvrir au moins ledit cylindre porte-plaque lors de l'impression,
ledit appareil étant caractérisé en ce qu'il comporteun organe (26) presseur de plaque monté sur ledit couvercle de sécurité (13) et susceptible de venir porter contre une partie d'extrémité de fuite de la plaque dans une position espacée desdits moyens de fixation de plaque d'une distance qui n'est pas supérieure à la longueur de la plaque mesurée entre l'extrémité d'attaque et de fuite de façon à appliquer une force dirigée vers le bas sur ladite plaque lorsque la partie d'extrémité d'attaque de ladite plaque (24) est introduite dans lesdits moyens de fixation (28) de plaque. - Appareil selon la revendication 1, dans lequel ledit organe presseur de plaque (26) comprend une dépression (26a) ouverte vers le bas pour y introduire ladite partie d'extrémité de fuite de la plaque, ladite dépression ouverte vers le bas comportant une surface supérieure s'ouvrant à un niveau inférieur à une position libre de ladite partie d'extrémité de fuite dans l'état d'ouverture dudit couvercle (13) de sécurité.
- Appareil selon la revendication 1 ou la revendication 2, dans lequel ledit couvercle de sécurité (13) comprend une partie supérieure comportant un organe de réception de plaque (21) et une partie inférieure comportant un élément de maintien de plaque (23), ledit organe de réception de plaque (21) supportant ladite plaque (24) et ledit élément de maintien de plaque (23)supportant ladite partie d'extrémité d'attaque de la plaque, maintenant ainsi la plaque.
- Appareil selon la revendication 3, dans lequel ledit organe presseur de plaque (26) est disposé entre ledit organe de réception de plaque (21) et ledit élément de maintien de plaque (23), et la plaque est maintenue par ledit organe presseur de plaque (26) et ledit organe de réception de plaque (21) montés à l'extérieur dudit couvercle de sécurité (13).
- Appareil selon l'une quelconque des revendications 1 à 4, comprenant en outre un guide plaque (25) de forme courbe disposé verticalement, positionné en dessous dudit organe (26) presseur de plaque et s'étendant à partir dudit couvercle de sécurité (13) de façon à être écarté de lui d'une distance prédéterminée en dessous dudit organe (26) presseur de plaque, ledit guide plaque (25) courbant la plaque (24) dont ladite partie d'extrémité de fuite est maintenue par ledit organe (26) presseur de plaque lors du montage de la plaque (24) sur ledit cylindre porte-plaque (3), de sorte que ladite partie d'extrémité d'attaque applique une force prédéterminée sur les moyens (28) de fixation de plaque dudit cylindre porte-plaque (3) dans lesquels la plaque (24) est introduite.
- Appareil selon la revendication 5, dans lequel ladite plaque (24) est entraînée vers le bas le long d'une surface interne courbe dudit guide plaque (25) lors de l'amenée de la plaque (24) audit cylindre porte-plaque (3), et ladite partie d'extrémité d'attaque de la plaque (24) qui est déplacée vers le bas est introduite et fixée aux moyens (28) de fixation de plaque dudit cylindre porte-plaque (3) disposés sur une ligne s'étendant à partir dudit couvercle de sécurité (13).
- Appareil selon l'une quelconque des revendications 1 à 6, comprenant en outre des moyens (28) de fixation de plaque côté d'attaque disposés dans un intervalle périphérique (27) dudit cylindre porte-plaque (3) et comportant des goupilles de référence (31) s'engageant respectivement avec des encoches de référence (32) formées au niveau de ladite partie d'extrémité d'attaque de la plaque (24), de sorte que ladite partie de fuite de la plaque (24) est pressée par ledit organe (24) presseur de plaque de façon à engager parfaitement lesdites goupilles de référence (31) avec lesdites encoches de référence (32) de ladite partie d'extrémité d'attaque de la plaque (24), assurant ainsi la fixation de ladite partie d'extrémité d'attaque de la plaque (24) par lesdits moyens de fixation (28) de plaque côté bord d'attaque.
