For, the transfer position of the printing plate 12 to be transferred next is shifted to the opposite side to the bending portion 21 side of the printing plate 12 transferred immediately before, and the bending portion 21 of the printing plate 12 to be transferred next is transferred. And the bending plate 21 of the printing plate 12 transferred immediately before, and the surface of the printing plate 12 to be transferred next is superimposed on the surface of the printing plate 12 transferred immediately before. It has a function to do. Further, the control unit of the sorting device 16 (transfer machine 35), based on the sorting information (job number) of the printing plate 12 read and acquired by the reading unit 29, sort information (job) of the printing plate 12 to be transferred next. 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 to be 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 is different from the sorting information (job number) of the printing plate 12 transferred immediately before, the transfer of the printing plate 12 to be transferred next is transferred. It has a function of shifting the loading position by a second shift amount L2 (see FIG. 4) 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 5 mm, for example. 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, FIG. 3 shows the plate storage unit 17. The plate storage unit 17 is configured by a printing plate carriage 48 that accommodates the printing plate 12 and can carry it. The printing plate carriage 48 has a base portion 49, casters 50 that run on the floor surface are attached to the bottom corners of the base portion 49, and an arm 51 that operates the printing plate carriage 48 is erected on the upper surface. .

  The printing plate carriage 48 has a bent portion 21 on one side of the printing plate 12 facing sideways (right side in FIG. 3), and a plurality of the printing plates 12 are faced with the printing plates 12 standing obliquely. 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 erected obliquely. Each standing portion 52 is provided with a placing portion 53 on which the lower edge portion of the standing printing plate 12 is placed. The standing portion 52 and the placing portion 53 form a storage space 54 in which a plurality of printing plates 12 are stacked and stored in a leaning state.

  As shown in FIGS. 1 and 2, each plate carriage 48 is positioned and mounted on each plate delivery section 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 printing plate 12 carried out from the plate making machine 11 is received by the direction changing machine 13 and carried out from the direction changing machine 13 to the vendor 14.

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

  The outer shape of the printing plate 12 is regulated by the positioning unit 28 of the vendor 14, and the printing plate 12 is positioned at a predetermined bending position in the vendor 14.

  The printing information display unit 24 of the printing plate 12 is read by the reading unit 29 of the vendor 14 and the printing information of the printing plate 12 is acquired.

  The bending portion 21 is bent on one side of the printing plate 12 by the plate bending unit 30 of the vendor 14.

  The printing plate 12 that has been read and bent by the conveying unit 27 and the unloading unit 31 of the vendor 14 is unloaded to the sorting device 16. Note that the printing plate 12 carried out from the vendor 14 to the sorting device 16 has the bending portion 21 located on one side orthogonal to the conveying direction.

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

  At this time, the sorting device 16 checks the sorting information such as the cart number (plate storage part number) of the sorting destination and the job number for each printed matter 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 unit 36 to a predetermined receiving position.

  For example, based on the acquired printing information of the printing plate 12, if the printing plate 12 is not transferred to the printing plate carriage 48 serving as a sorting destination, that is, if the printing plate carriage 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 carried out from the vendor 14 is received by the transfer unit 38 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 as a sorting destination, and the plate 12 is transferred from the transfer unit 38 to the plate carriage 48. At this time, the upper surface side of the transfer unit 38 is inclined toward the printing plate carriage 48, whereby the printing plate 12 on the transfer unit 38 is transferred to the printing plate carriage 48 and transferred.

  Thereafter, in order to receive the printing 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 printing plate receiving portion 36.

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

  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 bent portion 21 side of the printing plate 12 from the receiving position (origin position). The first shift amount L1, which is 5 mm, for example, is shifted in the direction, that is, the right direction in FIG. 1 or FIG.

  The next transfer printing plate 12 transferred from the vendor 14 is received by the transfer unit 38 whose receiving position is shifted. FIG. 2 shows a state in which the position of the printing plate 12 received in the transfer unit 38 is shifted with respect to FIG. Note that the printing plate 12 in FIG. 2 is the second printing plate 12 and shows a state in which the printing plate 12 is shifted larger than the first shift amount L1.

  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 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 is first on the opposite side (left side in FIG. 4) to the bending portion 21 side of the printing plate 12 to which the transfer position was transferred immediately before. Is shifted by the shift amount L1, and a gap is made between the bent portion 21 of the printing plate 12 to be transferred next and the bent portion 21 of the printing plate 12 transferred immediately before, and the printing to be transferred next. The plate 12 is transferred so that the surface of the plate 12 is superimposed on the surface of the plate 12 transferred immediately before.

  Thereafter, in order to receive the printing 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 printing plate receiving portion 36.

  If the next plate 12 to be transferred 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 plate. The plate 12 is shifted by adding the current first shift amount L1 in the direction corresponding to the bent portion 21 side of the plate 12, that is, in the right direction in FIG. That is, the shift amount is a value obtained by adding the current first shift amount L1 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 1) are transferred and stored in the printing plate carriage 48 while being shifted by the first shift amount L1.

  On the other hand, the destination of the printing plate 12 to be transferred next is the same printing 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 the same. If it is different from the job number of the printing plate 12 transferred immediately before (for example, job number 1), the stepping motor of the moving mechanism 39 is controlled so that the transfer unit 38 is bent from the receiving position (origin position). The shift is performed by adding the current second shift amount L2 in the direction corresponding to the section 21 side, that is, in the right direction in FIG. That is, the shift amount is equal to the shift amount of the transfer unit 38 at the time of receiving the printing plate 12 with a different job number (for example, job number 1) transferred immediately before the second shift amount L2 which is, for example, 30 mm. The value obtained by adding.

  The plate 12 having a different job number (for example, job number 2) to be transferred next is transferred from the vendor 14 to the transfer unit 38 whose receiving 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 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, a printing plate 12 with a different job number (for example, job number 2) to be transferred next is printed with a different job number (for example, job number 1) at which the transfer position was transferred immediately before. The plate 12 is shifted to the opposite side (left side in FIG. 4) with respect to the bent portion 21 side of the plate 12 by the second shift amount L2, and then the bent portion 21 of the printing plate 12 to be transferred next and the printing plate transferred immediately before. A large gap is formed between the 12 bent portions 21 and the surface of the printing plate 12 to be transferred next is transferred onto the surface of the printing plate 12 transferred immediately before.

  Thereafter, in order to receive the printing 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 printing plate receiving portion 36.

  If the next plate 12 to be transferred also 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 plate. The plate 12 is shifted by adding the current first shift amount L1 in the direction corresponding to the bent portion 21 side of the plate 12, that is, in the right direction in FIG. That is, the shift amount is a value obtained by adding the current first shift amount L1 to the shift amount of the transfer unit 38 when the printing plate 12 transferred immediately before is received.

  As described above, the printing plates 12 having the same job number (for example, job number 2) are shifted and stored in the printing plate carriage 48 while being shifted by the first shift amount L1.

  Therefore, as shown in FIGS. 3 and 4, a plurality of printing plates 12 are collected for each same job number in the printing plate carriage 48, and there is a large gap between the bent portions 21 of the printing plates 12 with different job numbers. Aki is sorted into groups of printing plates 12 with the same job number.

  Then, the printing plate carriage 48 in which the printing plate 12 is stored is run, the printing plate 12 is transported to the place of the printing machine, and the printing plate 12 is mounted on the printing cylinder of the printing machine. At this time, since the printing plates 12 having the same job number are sorted for each group, the printing plates 12 to be mounted on the same printing machine can be easily grasped, and erroneous mounting of the printing plates 12 can be prevented.

  As described above, according to the printing plate processing apparatus 10 of the present embodiment, the bending portion 21 provided on one side of the printing plate 12 is transferred to the printing plate carriage 48 in the horizontal direction, and a plurality of sheets are transferred to the printing plate carriage 48. For example, even if the printing plate 12 is thin and easily deformed, it is transferred to the state in which the surfaces of the plurality of printing plates 12 are overlapped without overlapping the bending portion 21 of the printing plate 12. It is possible to prevent deformation, and the bending portion 21 of the printing plate 12 housed in the printing plate carriage 48 is turned sideways, 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 confirmed. The handling of the printing plate 12 such as taking out can be improved.

  Furthermore, by increasing the shift amount between the groups of the printing plate 12 with different sorting information and increasing the gap between the bent portions 21, it can be easily distinguished for each group of the printing plate 12 with the same sorting information. As a result, the handling of the printing plate 12 can be improved.

  Note that the 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 non-processed plate, the machine reading by the reading unit 29 or the like is possible only by drawing the printing information on the printing plate 12, but it may be difficult to visually confirm. For this reason, when the printing plate 12 is mounted on the printing cylinder of the printing press, it may be difficult to determine which printing cylinder the printing plate 12 may be mounted.

  Therefore, as shown in FIG. 5, a print information adding unit 60 is installed in the vendor 14. The print information adding unit 60 reads the print information display unit 24 of the printing plate 12 by the reading unit 29, and based on the print information acquired, makes the print information display visible separately from the print information display unit 24 of the plate 12 Part (second print information display part) 61 is added to the printing plate 12.

  The print information adding unit 60 prints character information of the print information using, for example, an ink jet printer. Or you may make it provide the number of punch holes according to the position of the cylinder of a printing machine.

  In this way, when the printing plate 12 is a non-processed plate, even if it is difficult to visually recognize the printing information on the printing plate 12, the printing information can be easily visually recognized by adding visible printing information, and the printing plate can be handled. Can be improved.
