Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic plate feeder (auto feeder) for supplying a plate material plate such as an image-exposed photosensitive plate to a machine such as an automatic developing machine, and more particularly to an automatic plate feeder for reducing the installation space. Regarding the structure of the device.

[0002]

[Prior Art]

 When using an automatic processor to process a photosensitive plate (a photosensitive layer whose solubility is changed by light irradiation is appropriately coated on both sides or one side of a support plate made of a metal plate such as an aluminum plate) In many cases, an automatic plate feeder (auto feeder) that is directly connected to an automatic developing machine and continuously supplies a large number of photosensitive plates to the automatic developing machine is used.

By the way, the above-mentioned photosensitive plate is a thick metal-based sensitive material as described above, and has a large area. Therefore, there are the following restrictions in handling. (1) Handling is poor unless there is a fairly large space. (2) If you hold it in an unreasonable posture, it will be bent. (3) In the automatic plate feeder, if the conveying path is changed in direction to a steep angle, creases are formed.

Therefore, the automatic plate feeder is conventionally configured to meet a requirement that it can be handled in a considerably large space, does not hold in an unreasonable posture, and has a simple transport path.

[0005]

[Problems to be solved by the device]

 For this reason, conventionally, when an automatic plate feeder is attached to an automatic developing machine, a considerably large space is required on the side of the automatic developing machine, and the automatic developing machine itself becomes large in size, so that a large amount of space is required in a room or the like. It occupies a large space and reduces the number of units installed per area, resulting in poor efficiency.

For example, conventionally known automatic plate feeders include a horizontal type as shown in FIG. 7 and a vertical type as shown in FIG. That is, the horizontal type automatic plate feeder 1 is configured such that, for example, a plurality of exposed photosensitive plates 4 are leveled on a plate feeding table 3 installed in series on the photosensitive plate insertion port side of the automatic processor 2. The photosensitive plates 4 are stacked and stocked one by one, and the photosensitive plates 4 are adsorbed one by one from above by using a suction cup 5 and sequentially fed to the automatic developing machine 2 by a conveying means such as a conveyor 6.

The vertical type automatic plate feeder 7 is configured, for example, by arranging a plurality of exposed photosensitive plates in a vertical direction on a plate feeding table 8 installed on the photosensitive plate insertion opening side of the automatic developing machine 2. The photosensitive plates are stocked one by one, and the photosensitive plates are sequentially fed to the automatic developing machine 2 by the conveying means 9. The horizontal type automatic plate feeder 1 requires a large installation space outside the automatic developing machine 2. The vertical automatic plate feeder 7 has a smaller installation space than the horizontal automatic plate feeder 1, but still requires a large space.

Further, a plurality of photosensitive plates 4 stocked on the plate feeding tables 3, 9 can be continuously fed to the automatic developing machine 2 one by one, but especially, the plate feeding tables 3, 9 are Since there is no insertion part or guide part for cutting in another photosensitive plate 4 which is not stocked above, it is difficult to insert an interrupt from the middle. The direction of the arrows in FIGS. 7 and 8 is the direction in which the photosensitive plate 4 is inserted by interruption from the middle.

In view of the conventional circumstances as described above, the present invention is compact and has a small installation space, and it is possible to easily feed in another photosensitive plate that is not in stock from the middle, which is highly useful. It is an object to provide an automatic plate feeding device.

[0010]

[Means for Solving the Problems]

 For this reason, the automatic plate feeder of the present invention is arranged on the upper surface of the device for supplying plate material plates, and has a plate feed table for horizontally stacking and mounting a plurality of plate material plates and a plate material for the device. The feeding means that captures and lifts the edge of the plate material plate located on the plate insertion port side, and moves to the outside of the device at the lifting position to separate it, and the plate material plate insertion port side of the device. A conveyance path that is convexly curved toward the outside of the device and that is provided with the plate material plate detachment position by the supply means as the transport inlet port and the plate material plate insertion port position of the device as the transport outlet port. The transport means is configured to include transport elements arranged along the transport means, and another transport path from the outer side of the device to the transport outlet as a transport inlet.

[0011]

[Action]

 In such a configuration, a plurality of plate material plates are placed on the plate supply table. Next, the supply means captures and lifts the end of the plate material plate, and moves to the outside of the device at the lifted position to separate it. At the same time when the transportation by the transportation means is started, the capture of the plate material plate by the supply means is released. Then, when the transportation by the transportation means is started, the plate material plate is transported in a curved state along the transportation path, and the leading end of the plate material plate passes through the transportation outlet and is inserted into the insertion port of the automatic developing machine. ..

According to this structure, the automatic plate feeding device can be provided by utilizing the space above the automatic developing machine and the space on the slightly outer side, and the installation space can be reduced. In such a case, a considerably large space is not required, and the automatic processor itself can be compacted. In a room, etc., the number of installations per area can be increased, and the operation efficiency can be improved.

[0013] Further, since the other side of the device is used as a transfer inlet and another transfer path is provided to reach the transfer outlet at the plate material plate insertion port of the device, a plurality of plates stocked on the plate supply table is provided. In addition to continuously feeding the material plates one by one to the equipment, another plate material plate that is not stocked on the plate supply table can be easily inserted in the middle of the process, thus improving the utilization.
