Description

[Detailed description of the invention] The present invention is designed to prevent the surface of the plate material for printing plate production such as Al□ board or the photosensitive resin layer coated on the surface thereof from being damaged.
A plate material is taken out from a stacked plate group, which is a stack of plate materials and mounts for printing plate production, and applied to the surface of the plate material using a plate-making device that applies photosensitive resin to the surface of the plate material. It was developed to automatically and efficiently separate the plate material and mount, which is necessary when feeding the photosensitive resin layer to an exposure device that prints characters and designs for printing. A mechanism is provided on the side of the table on which the group of laminated plates is placed, and a mechanism is provided for separating plates and mounts from the group of laminated plates and taking them out one by one alternately. The present invention relates to an improvement in the apparatus for sorting plate materials for printing plate production, which includes a device for organizing and storing mounts in a stacked state.

Generally, the thickness of the mount inserted between adjacent plate materials is 7/1.
Due to the thinness of 00~8/100 mm, it was considered to provide a mount organizer and storage device to prevent the removed mounts from being scattered around, but Japanese Patent Application Laid-Open No. 52-12
As shown in Publication No. 4664, arranging the mount arrangement and storage device requires a large area in terms of plane, and moreover, it is necessary to place the mount arrangement and storage device in a position where the mount transfer guide path from the table to the mount arrangement and storage device is bent. When a mount organizing/accommodating device is deployed, the mount becomes curly and tends to wind up in a roll, making it difficult to store and organize.Furthermore, if work space is limited, deploying a mount organizing/accommodating device becomes extremely difficult. It was very difficult.

In view of the above-mentioned points, the present invention has been developed to reduce the overall size of the mount arrangement and storage device, which is installed in the device for sorting plate materials for printing plate production, and to facilitate the storage of mounts. The purpose is to

The device for sorting plate materials for printing plate production of the present invention is provided with a table on which a group of laminated plate materials, which are plates for printing plate production and mounts are stacked alternately, is placed, and on the side of this table, A plate for printing plate production, comprising a mechanism for separating the plates and mounts from the group of laminated plates and taking them out one by one alternately, and a device for arranging and storing the mounts taken out by this mechanism in a stacked state. To sort the materials, press a button on the device, arrange the mount organizing and storing device at a position below the table, and place the mounts taken out by the take-out mechanism between the mount organizing and accommodating device and the table in a stretched position. It is characterized by the provision of a transfer guide device consisting of a roller for bending and guiding the transfer and a movable chute.

Therefore, the following effects are achieved.

■ Since the mount organizing and storing device is placed below the table, the two-dimensional work area is reduced, making the whole compact.
It can now be used in narrow spaces.

＠ The mount arrangement storage device from the upper table to the lower mount Since the old mount transport guide route was inevitably crooked and muddy,
The drawback that the backing paper gets bent and winds up in a roll shape due to the bending transfer can be safely resolved by guiding the backing paper in a stretched position using the transfer guide device. It became possible to accumulate and store the
