Automatic plate making machine equipped with photosensitive printing plate supplying apparatus and printing plate packaging means
View Patent ↗A photosensitive printing plate supplying apparatus for supplying a photosensitive printing plate to an automatic plate making machine for a photosensitive printing plate includes a printing plate packaging device which accommodates a bundle of photosensitive printing plates; a printing plate accommodating portion to which the printing plate packaging device is removably attached and which can completely shield light from the exterior; and a taking-out/conveying device which takes out the photosensitive printing plates from an interior of the printing plate packaging device in the light-shielded accommodation portion and conveys the photosensitive printing plates to a predetermined position. When the printing plate packaging means has an opening/closing lid, the photosensitive printing plate supplying apparatus may further include a lid opening/closing device. In this case, the lid opening/closing device operates in an interlocking manner with the taking-out/conveying device and is opened when the taking-out operation by the taking-out/conveying device is started, and is closed when the taking-out operation is completed.
1. A printing plate packaging box comprising:
a box main body which accommodates a bundle of photosensitive printing plates, which are not sealed within a light-shielding wrapper, and which is provided with a supply opening through which the photosensitive printing plates are taken out, said photosensitive printing plates being in direct contact with said box main body;
an opening/closing lid which is removably attached to said box for opening/closing the supply opening; and
a light-shielding member which prevents direct entry of light from outside into the inside of the box main body, provided in the vicinity of a zone in which the box main body and the opening/closing lid are contacted to each other in an assembled state, the light-shielding member being connected to the opening/closing lid such that the light-shielding member blocks the direct entry of light from outside into the inside of the box through the zone in which the box main body and the opening/closing lid are contacted to each other in the assembled state, and said light-shielding member being circumferentially larger than said box main body such that said light-shielding member surrounds and covers an outermost portion of said box main body,
wherein a sheet-type material of which surface is smooth and air tight is adhered onto an outer surface of said opening/closing lid.
2. A printing plate packaging box according to claim 1 , wherein said opening/closing lid is disposed on a top surface of the box main body.
3. A printing plate packaging box according to claim 1 ,
wherein the light-shielding member is configured such that an inner portion of the light-shielding member is in sliding contact with an outermost portion of the box main body when the lid is removed from the box main body.
4. A printing plate packaging box according to claim 1 , wherein the sheet-type material is positioned to be parallel with the bundle of photosensitive printing plates.
5. A combination of a printing plate packaging box and a bundle of photosensitive printing plates, comprising:
said bundle of photosensitive printing plates which are not sealed within a light shielding wrapper; and
said printing plate packaging box including;
a box main body which accommodates said bundle of photosensitive printing plates and which is provided with a supply opening through which said photosensitive printing plates are taken out, said photosensitive printing plates being in direct contact with said box main body;
an opening/closing lid which is removably attached to said box for opening/closing the supply opening; and
a light-shielding member being connected to the opening/closing lid such that the light-shielding member blocks the direct entry of light from outside into inside of the box through a zone in which the box main body and the opening/closing lid are contacted to each other in the assembled state, and said light-shielding member being circumferentially larger than said box main body such that said light-shielding member surrounds and covers an outermost portion of said box main body,
wherein a sheet-type material of which surface is smooth and air tight is adhered onto an outer surface of said opening/closing lid.
6. A combination of a printing plate packaging box and a bundle of photosensitive printing plates according to claim 5 ,
wherein the light-shielding member is configured such that an inner portion of the light-shielding member is in sliding contact with an outermost portion of the box main body when the lid is removed from the box main body.
7. A combination of a printing plate packaging box and a bundle of photosensitive printing plates according to claim 5 , wherein the sheet-type material is positioned to be parallel with the bundle of photosensitive printing plates.
8. A printing plate packaging box comprising:
a box main body which accommodates a bundle of photosensitive printing plates, which are not sealed within a light-shielding wrapper, and which is provided with a supply opening through which the photosensitive printing plates are taken out, said photosensitive printing plates being in direct contact with said box main body;
an opening/closing lid which is for opening/closing the supply opening, the lid being detachable from the box; and
a light-shielding member which prevents direct entry of light from outside into the inside of the box main body, provided in the vicinity of a zone in which the box main body and the opening/closing lid are contacted to each other in an assembled state, the light-shielding member being connected to the opening/closing lid such that the light-shielding member blocks the direct entry of light from outside into the inside of the box through the zone in which the box main body and the opening/closing lid are contacted to each other in the assembled state, and said light-shielding member being circumferentially larger than said box main body such that said light-shielding member surrounds and covers an outermost portion of said box main body,
wherein a sheet-type material of which surface is smooth and air tight is adhered onto an outer surface of said opening/closing lid.
9. A printing plate packaging box according to claim 8 ,
wherein the light-shielding member is configured such that an inner portion of the light-shielding member is in sliding contact with an outermost portion of the box main body when the lid is removed from the box main body.
10. A printing plate packaging box according to claim 8 , wherein the sheet-type material is positioned to be parallel with the bundle of photosensitive printing plates.
