Regarding, the shift position of the plate 12 to be transferred next is shifted to the opposite side to the side of the bent part 21 of the plate 12 transferred immediately before, and the bent part 21 of the plate 12 to be transferred next is shifted. And a bending portion 21 of the printing plate 12 transferred immediately before are placed, and the surface of the printing plate 12 to be transferred next is transferred to the surface of the printing plate 12 transferred immediately before. It has the function to Further, in the control unit of the sorting device 16 (transfer device 35), based on the sorting information (job number) of the printing plate 12 read by the reading unit 29, the sorting information of the printing plate 12 to be transferred next (job If the number) is the same as the sorting information (job number) of the printing plate 12 transferred immediately before, the transfer position of the printing plate 12 transferred next is the first shift amount L1 (see FIG. 4). If the sorting information (job number) of the printing plate 12 to be transferred next is different from the sorting information (job number) of the printing plate 12 transferred immediately before, the printing plate 12 to be transferred next is moved. It has a function of shifting the mounting position by a second shift amount L2 (see FIG. 4) which is larger than the first shift amount L1.

The first shift amount L1 is a shift amount larger than the thickness of the printing plate 12, and is, for example, 5 mm. The second shift amount L2 is, for example, 30 mm, which is larger than the width of the bent portion 21 of the printing plate 12.

Next, the plate storage unit 17 is shown in FIG. The plate storage unit 17 is composed of a plate carriage 48 that can store and carry the plate 12 therein. The plate carriage 48 has a base 49, casters 50 running on the floor surface are attached to the four corners of the bottom surface of the base 49, and arms 51 for operating the plate carriage 48 are provided upright on the upper surface. ..

In the plate carriage 48, the bent portion 21 on one side of the plate 12 is oriented horizontally (on the right side in FIG. 3), and the plates 12 are placed in an inclined state and the surfaces of the plates 12 are Store in a stacked state.

On the upper surface of the printing plate carriage 48, a plurality of standing portions 52 for leaning the printing plate 12 are obliquely provided. Each standing portion 52 is provided with a placing portion 53 on which the lower edge of the printing plate 12 to be placed is placed. A storage space 54 for accommodating and stacking a plurality of printing plates 12 in a leaning state is formed by the leaning portion 52 and the placing portion 53.

Then, as shown in FIGS. 1 and 2, each plate carriage 48 is positioned and mounted on each plate sending portion 37 of the sorting device 16 with the storage space 54 facing the sorting device 16.

Next, the operation of the plate processing apparatus 10 will be described.

The plate 12 delivered from the plate making machine 11 is received by the direction changer 13 and is delivered from the direction changer 13 to the bender 14.

Then, the vendor 14 receives the printing plate 12 delivered from the direction changer 13 in the transport unit 27 and transports it into the vendor 14.

The positioning unit 28 of the bender 14 regulates the outer shape of the printing plate 12, and positions the printing plate 12 at a predetermined bending position in the bender 14.

The reading unit 29 of the vendor 14 reads the printing information display unit 24 of the printing plate 12 to obtain the printing information of the printing plate 12.

The plate bending unit 30 of the bender 14 bends the bending portion 21 on one side of the printing plate 12.

The transport unit 27 and the unloading unit 31 of the bender 14 unload the printing plate 12 for which printing information reading and bending have been completed to the sorting device 16. The plate 12 carried out from the bender 14 to the sorting device 16 has the bending portion 21 located on one side orthogonal to the carrying direction.

Further, in the sorting device 16, the transfer unit 38 is moved to the plate receiving portion 36 that receives the plate 12 carried out from the vendor 14.

At this time, the sorting device 16 confirms the sorting information such as the trolley number of the sorting destination (storing plate number) and the job number of each printed material from the acquired printing information of the printing plate 12, thereby stepping the moving mechanism 39. The motor is controlled to move the transfer unit 38 in the plate receiving portion 36 to a predetermined receiving position.

For example, based on the acquired printing information of the plate 12, if the plate 12 is not transferred to the plate carrier 48 that is the sorting destination, that is, if the plate carrier 48 is empty, the transfer unit 38 Is moved to the receiving position (origin position) of the first sheet of the first job.

The printing plate 12 delivered from the bender 14 is received by the transfer unit 38 that has moved to the receiving position (origin position).

The stepping motor of the moving mechanism 39 is controlled to move the transfer unit 38 to a fixed position of the plate sending unit 37 which is a sorting destination, and the plate 12 is transferred from the transfer unit 38 to the plate carriage 48. At this time, by tilting the upper surface side of the transfer unit 38 toward the plate carriage 48, the plate 12 on the transfer unit 38 is delivered to the plate carriage 48 and transferred.

After that, in order to receive the plate 12 to be transferred next, the stepping motor of the moving mechanism 39 is controlled to move the transfer unit 38 to the receiving position (origin position) of the plate receiving portion 36.

Then, when the printing information of the printing plate 12 to be transferred next is acquired, if the sorting destination of the printing plate 12 to be transferred next is the same plate carriage 48 as the printing plate 12 transferred immediately before, It is confirmed whether the job number of the printing plate 12 to be transferred next (for example, job number 1) is the same as the job number of the printing plate 12 transferred immediately before (for example, job number 1).

If the job numbers (for example, job number 1) are the same, the stepping motor of the moving mechanism 39 is controlled so that the transfer unit 38 corresponds to the bending portion 21 side of the plate 12 from the receiving position (origin position). The direction, that is, the right direction in FIG. 1 or 2, is shifted by a first shift amount L1 of 5 mm, for example.

The printing unit 12 to be transferred next from the vendor 14 is received by the transfer unit 38 whose reception position is shifted. FIG. 2 shows a state in which the position of the printing plate 12 received by the transfer unit 38 is shifted with respect to FIG. The printing plate 12 in FIG. 2 is the printing plate 12 for the few sheets, and shows a state in which the printing plate 12 is shifted by a larger amount than the first shift amount L1.

By controlling the stepping motor of the moving mechanism 39, the transfer unit 38 is moved to a fixed position of the plate sending unit 37 as a sorting destination, and the plate 12 is transferred from the transfer unit 38 to the plate carriage 48.

As a result, as shown in FIG. 4, the printing plate 12 to be transferred next has the first transfer position on the opposite side (left side in FIG. 4) to the bent portion 21 side of the printing plate 12 transferred immediately before. The amount of shift L1 of the printing plate 12 is shifted, and a gap is formed between the bending portion 21 of the printing plate 12 to be transferred next time and the bending portion 21 of the printing plate 12 transferred immediately before, and the printing to be transferred next time. The surface of the plate 12 is transferred in a state of being superposed on the surface of the printing plate 12 transferred immediately before.

After that, in order to receive the plate 12 to be transferred next, the stepping motor of the moving mechanism 39 is controlled to move the transfer unit 38 to the receiving position (origin position) of the plate receiving portion 36.

If the printing plate 12 to be transferred next has the same job number (for example, job number 1), the stepping motor of the moving mechanism 39 is controlled to move the transfer unit 38 from the receiving position (origin position) to the printing position. The first shift amount L1 for this time is added and shifted in the direction corresponding to the bent portion 21 side of the plate 12, that is, in the right direction of FIG. 1 or 2. That is, the shift amount is a value obtained by adding the first shift amount L1 of this time to the shift amount of the transfer unit 38 when the printing plate 12 transferred immediately before is received.

In this way, the plate 12 having the same job number (for example, job number 1) is transferred by the first shift amount L1 by the shift amount L1 and transferred and stored on the plate carriage 48.

On the other hand, the sorting destination of the printing plate 12 to be transferred next is the same plate carriage 48 as the printing plate 12 transferred immediately before, but the job number (for example, job number 2) of the printing plate 12 to be transferred next is When the job number of the plate 12 transferred immediately before is different from the job number (for example, job number 1), the stepping motor of the moving mechanism 39 is controlled to bend the plate unit 12 from the receiving position (origin position). The second shift amount L2 of this time is added and shifted in the direction corresponding to the portion 21 side, that is, in the right direction of FIG. 1 or 2. That is, the shift amount is equal to the shift amount of the transfer unit 38 at the time of receiving the plate 12 having a different job number (for example, job number 1) transferred immediately before, which corresponds to the second shift amount L2 which is, for example, 30 mm this time. Is the value obtained by adding.

The platen 12 having a different job number (for example, job number 2) to be transferred next from the vendor 14 is received by the transfer unit 38 whose reception position is shifted.

The stepping motor of the moving mechanism 39 is controlled to move the transfer unit 38 to a fixed position of the plate sending unit 37 which is a sorting destination, and the plate 12 is transferred from the transfer unit 38 to the plate carriage 48.

As a result, as shown in FIG. 4, the printing plate 12 having a different job number (for example, job number 2) to be transferred next is a printing plate having a different job number (for example, job number 1) transferred immediately before the transfer position. The bending portion 21 of the printing plate 12 to be transferred next and the printing plate transferred immediately before are shifted to the opposite side (left side in FIG. 4) of the plate 12 by the second shift amount L2. A large gap is formed between the plate 12 and the bent portion 21, and the surface of the plate 12 to be transferred next is transferred in a state of being superimposed on the surface of the plate 12 transferred immediately before.

After that, in order to receive the plate 12 to be transferred next, the stepping motor of the moving mechanism 39 is controlled to move the transfer unit 38 to the receiving position (origin position) of the plate receiving portion 36.

If the printing plate 12 to be transferred next has the same job number (for example, job number 2), the stepping motor of the moving mechanism 39 is controlled to move the transfer unit 38 from the receiving position (origin position) to the printing position. The first shift amount L1 for this time is added and shifted in the direction corresponding to the bent portion 21 side of the plate 12, that is, in the right direction of FIG. 1 or 2. That is, the shift amount is a value obtained by adding the first shift amount L1 of this time to the shift amount of the transfer unit 38 when the printing plate 12 transferred immediately before is received.

In this way, the printing plates 12 having the same job number (for example, job number 2) are transferred by the first shift amount L1 by the first shift amount L1 and transferred and stored on the printing plate carriage 48.

Therefore, as shown in FIG. 3 and FIG. 4, the plate carriage 48 has a plurality of plate plates 12 grouped for the same job number, and a large gap is formed between the bent portions 21 of the plate plates 12 having different job numbers. Aki, sorted by each group of printing plates 12 with the same job number.

Then, the printing plate carriage 48 in which the printing plates 12 have been stored is run, the printing plates 12 are transported to the location of the printing machine, and the printing plates 12 are mounted on the printing cylinder of the printing machine. At this time, since the printing plates 12 having the same job number are sorted into groups, it is possible to easily grasp the printing plates 12 to be mounted on the same printing machine and prevent the printing plates 12 from being erroneously mounted.

As described above, according to the plate processing apparatus 10 of the present embodiment, the bending portion 21 provided on one side of the plate 12 is laterally transferred to the plate carriage 48, and at the same time, a plurality of plates are mounted on the plate carriage 48. Since the surfaces of the plurality of printing plates 12 are transferred to each other without overlapping the bent portions 21 of the printing plate 12, even if the printing plate 12 is thin and easily deformed, Deformation can be prevented, and moreover, the bending portion 21 of the printing plate 12 housed in the printing plate carriage 48 is set to be horizontal, and a gap is formed between the bending portions 21 of the plurality of printing plates 12, so that the printing plate 12 can be checked and The handling property of the printing plate 12 such as taking it out can be improved.

Furthermore, by increasing the amount of shift between groups of plate 12 having different assortment information and increasing the gap between bent portions 21, it is possible to easily distinguish each group of plate 12 having the same assortment information. Sorting can be performed, and handling of the printing plate 12 can be improved.

The printing plate 12 made by the plate making machine 11 may be an unprocessed plate that is not subjected to development processing. In the case of this unprocessed plate, although the printing information is only drawn on the printing plate 12, the mechanical reading by the reading unit 29 or the like is possible, but it may be difficult to visually confirm. Therefore, when the printing plate 12 is mounted on the printing cylinder of the printing machine, it may be difficult to know which printing cylinder the printing plate 12 should be mounted on.

Therefore, as shown in FIG. 5, the print information adding unit 60 is installed in the vendor 14. The print information adding unit 60 displays the print information separately from the print information display unit 24 of the printing plate 12 based on the print information acquired by reading the print information display unit 24 of the printing plate 12 by the reading unit 29. A section (second print information display section) 61 is added to the printing plate 12.

The print information adding unit 60 uses, for example, an inkjet printer to print the character information of the print information. Alternatively, a number of punch holes may be provided according to the position of the printing cylinder of the printing machine.

In this way, when the printing plate 12 is an unprocessed plate, even if the printing information on the printing plate 12 is difficult to see, the printing information can be easily viewed by adding the visible printing information. It is possible to improve the property.
