ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a printing press comprising a printing plate guiding device for guiding a new printing plate supplied to a plate cylinder or a discharged printing plate discharged from the plate cylinder.
2. Prior art
A conventional printing press comprising a printing plate guiding device for guiding a new printing plate supplied to a plate cylinder or a discharged printing plate discharged from the plate cylinder has previously been disclosed in Japanese Utility Model Registration No. 3032484.
In the device disclosed in Japanese Utility Model Registration No. 3032484, a holding member for guiding a discharged printing plate or a new printing plate is pivotally provided at a location near a plate cylinder. The holding member can be shifted between a discharged printing plate guiding position and a new printing plate guiding position by an operation unit.
In a printing press disclosed in Japanese Utility Model Registration No. 3032484, a holding member is provided at a location near a plate cylinder. Thereby, an operation space for checking the plate cylinder, etc. is restricted and operation efficiency is decreased.
To resolve the above drawback, for example, a printing press disclosed in Japanese Patent Laid-Open (Kokai) Publication No. 6-31901, a thin plate is swingably supported at a cover member upwardly movable. By pivotally moving the thin plate, a holding member can be shifted between a guiding position for guiding a discharged printing plate or a new printing plate and a shelter position and the maintenance of the plate cylinder and so on can be easily operated by upwardly moving the thin plate by increasing the cover member.
However, in the printing press disclosed in Japanese Patent Laid-Open (Kokai) Publication No. 6-31901, a sufficient space should be provided above a printing unit, since the operation space near the plate cylinder is formed by increasing the thin plate together with the cover member.
To address the above drawbacks, a purpose of the present invention is to provide a printing press which can form an operation space at a location near a plate cylinder even if a sufficient space can not be provided above a printing unit.
SUMMARY OF THE INVENTION
To resolve the above described drawbacks, a printing press according to the present invention comprises a pair of right- and left- frames, a first printing plate guide means provided at a location near a plate cylinder, the first printing plate guide means swingably supported so as to be moved between a guiding position for guiding a new printing plate supplied to the plate cylinder or a discharged printing plate discharged from the plate cylinder and a shelter position released from the plate cylinder, a second printing plate guide means provided at a location near the plate cylinder, the second printing plate guide means swingably supported so as to be moved between a guiding position for guiding a new printing plate supplied to the plate cylinder or a discharged printing plate discharged from the plate cylinder and a shelter position released from the plate cylinder, and a cover member swingably supported so as to be moved between a closing position for closing at least one part of a space formed between the pair of right- and left- frames and a releasing position for releasing the space, wherein a pivot axis of the first printing plate guiding means, a pivot axis of the second printing plate guiding means and a pivot axis of the cover are coaxial.
In the above described printing press, the printing press is characterized of comprising discharged printing plate storing means with a storing space for storing the discharged printing plate discharged from a plate cylinder, new printing plate storing means with a storing space for storing the new printing plate supplied to the plate cylinder, and a printing plate holding means swingably supported by the cover, the printing plate holding means movable between a shelter position for positioning the storing spaces of the discharged printing plate storing means and the new printing plate storing means at an exterior side of the cover and an operation position located at a location near the first printing plate guide means located at the guiding position.
In the above described printing press, the printing press is characterized in that the first printing plate guiding means comprises a switching guide swingably supported, the switching guide movable between a discharged printing plate guiding position for guiding the discharged printing plate discharged from the plate cylinder to the discharged printing plate storing means of the printing plate holding means located at the operation position and the new printing plate from the new printing plate storing means of the printing plate holding means located at the operation position to said plate cylinder.
