[Problems to be solved by the invention]
However, in the case of the conventional packaging material for printing plates, since the printing plate is heavy, it is necessary to set it in a cassette several times. For this reason, when the printing plate is refilled from the packaging material for the printing plate into the cassette, there is a risk of damaging the recording layer of the printing plate. Therefore, careful work is required. Furthermore, the work effort of the worker is also difficult.
[0006]
In view of the above facts, the present invention has an object to provide a printing plate packaging material that can reliably prevent damage to the recording layer of the printing plate and that can reduce the labor of the operator. It is.
[0007]
[Means for Solving the Problems]
The packaging material for a printing plate according to the first aspect of the present invention is a packaging material for a printing plate to be used for packaging an unused printing plate having a recording layer provided on a support, and the upper surface is unpacked. The packaging material body has a box-like packaging material body whose surface is a non-unpacking surface, and the packaging material body is provided with a cutting portion for separating the upper surface or the lower surface from the packaging material body. The upper surface or the lower surface is separated from the cutting portion, and the plate can be directly loaded into the plate feeding portion of the image forming apparatus with the separated side facing upward.
[0008]
The packaging material for a printing plate according to the second aspect of the present invention is a packaging material for a printing plate that is used for packaging an unused printing plate having a recording layer provided on a support, the top surface of which is open. A box-shaped packing material body, and a lid body that closes the top surface of the packaging material body during packaging and is removed during unpacking to open the top surface of the packaging material body. It is characterized in that it can be directly loaded into the plate supply section of the image forming apparatus in a detached state.
[0009]
A packaging material for a printing plate according to a third aspect of the present invention is the packaging material for a printing plate according to the first or second aspect, wherein at least one of outer shape information and physical property information of the printing plate is encoded. Or at least one of the outer shape information and the physical property information is encoded and recorded on an information recording medium, and the information recording medium is attached to the surface of the packaging material for a printing plate. .
[0010]
According to the first aspect of the present invention, an unused printing plate having a recording layer provided on a support is packaged and shipped in a printing plate packaging material.
[0011]
Here, in this invention, since the cutting part is provided in the upper surface or lower surface of the packaging material for printing plates, an upper surface or a lower surface can be cut | disconnected from a cutting part in a shipping destination, and can be isolate | separated from a packaging material main body. When the upper surface or the lower surface is separated from the packaging material main body, the printing plate housed inside appears. At this time, when the printing plate is accommodated in the packaging material body so that the recording layer is on the lower side (support is the upper side) at the time of shipment, the upper surface, which is the unpacking surface, is separated from the packaging material body. A printing plate packaging material provided with a cutting portion is used. On the other hand, when the printing plate is accommodated in the packaging material body so that the recording layer is on the upper side (support is on the lower side) at the time of shipment, the lower surface, which is a non-unpacking surface, is separated from the packaging material body. A printing plate packaging material provided with a cutting portion is used, and once it is turned upside down during unpacking, the lower surface, which is a non-unpacking surface, is cut and separated. In this way, when the upper surface or the lower surface is separated from the packaging material body, the printing plate support always appears.
[0012]
Then, the printing plate packaging material is directly loaded into the plate supply unit of the image forming apparatus with the separated side facing upward. In the image forming apparatus, the printing plates positioned in the uppermost layer of the printing plate packing material loaded in the plate feeding unit are individually fed one by one, but the printing positioned in the uppermost layer of the printing plate packing material is performed. Since the plate always faces the support side upward, the recording layer of the printing plate is not damaged during sheet feeding.
[0013]
In addition, according to the present invention, the printing plate packaging material is directly loaded into the plate feeding portion of the image forming apparatus, that is, the printing plate packaging material is used in place of the conventional cassette. There is no need to refill the printing plate from material to cassette. Accordingly, the work effort of the operator is reduced.
[0014]
According to the second aspect of the present invention, an unused printing plate having a recording layer provided on a support is packaged and shipped in a printing plate packaging material.
[0015]
Here, in the present invention, the printing plate packaging material is configured to include a box-shaped packaging material body and a lid body that closes an upper surface that is an open surface of the packaging material body. The lid can be removed. When the lid is removed, the upper surface of the packaging material body is opened, and the printing plate stored inside appears. At this time, if the printing plate is accommodated in the packing material main body so that the recording layer is on the lower side (support is on the upper side) at the time of shipment, the printing plate support always appears when unpacked.
[0016]
Then, with the lid removed, the packing material body is directly loaded into the plate supply unit of the image forming apparatus. In the image forming apparatus, the printing plates positioned in the uppermost layer of the printing plate packing material loaded in the plate feeding unit are individually fed one by one, but the printing positioned in the uppermost layer of the printing plate packing material is performed. Since the plate always faces the upper side of the apparatus, the recording layer of the printing plate is not damaged during sheet feeding.
[0017]
Moreover, according to the present invention, since the packaging material body of the printing plate packaging material is directly loaded into the plate feeding portion of the image forming apparatus, that is, the printing plate packaging material is used instead of the conventional cassette, There is no need to refill the printing plate from the printing plate packaging material into the cassette. Accordingly, the work effort of the worker is reduced.
[0018]
Further, in the case of the present invention, unlike the invention according to claim 1 in which a part of the printing plate packaging material is cut, the printing plate packaging material is configured to have a packaging material body and a lid. Therefore, when the printing plate is used up, it is possible to cover the empty packing material body with the lid and return it to the manufacturer. For this reason, it can contribute to the recycling of the packaging material for printing plates.
[0019]
According to the third aspect of the present invention, at least one of the outer shape information and the physical property information of the printing plate to be packed is encoded and displayed on the surface of the packaging material for the printing plate, or the outer shape information and the physical property information At least one of them is encoded and recorded on an information recording medium, and the information recording medium is attached to the surface of the above-mentioned printing plate packaging material. Alternatively, it is possible to input a part or all of the information related to the printing plate necessary for processing only by reading the information recording medium using the information reading device provided in the printing plate processing device. Accordingly, it is possible to save the operator from manually checking individual information and inputting the information to the printing plate processing apparatus, or to eliminate the input work itself. As a result, even if the types of printing plates are different, the occurrence of troubles due to the differences can be greatly reduced. Furthermore, since the operator's manual input work can be greatly reduced or eliminated, there is no possibility of erroneous input and work efficiency can be greatly improved.

[0035]
[Configuration of packing box 38]
Next, the configuration of the packaging box 38 according to the main part of the present embodiment will be described.
[0036]
1A shows the packing box 38 in a packed state, and FIG. 1B shows the packing box 38 in an unpacked state. As shown in these drawings, the packing box 38 as the “printing plate packing material” and the “packing box body” is constituted by a relatively thin rectangular parallelepiped-shaped recycled cardboard. In FIG. 1B, the thickness of the packaging box 38 is not shown, and reference numeral 44 represents a slight gap between the packaging box 38 and the printing plate 12.
[0037]
The packing box 38 has an upper surface 38A as an unpacking surface and a lower surface 38B as a non-unpacking surface. When packing, the pair of unpacking portions 38A1 and 38A2 constituting the upper surface 38A are closed to form a gum tape or the like. The configuration is sealed with the adhesive tape 46.
[0038]
In the packing box 38 configured as described above, a predetermined number of unused printing plates 12 are accommodated in a stacked state. In the case of the present embodiment, as noted in FIG. 1A, the back surface (B surface) 12A of the printing plate 12 is the upper surface 38A side (in other words, the photosensitive surface (E surface) 12B of the printing plate 12). Is on the lower surface 38B side), the printing plate 12 is accommodated in the packing box 38. Note that a thin film-like interleaf paper 48 is interposed between the photosensitive surface 12B of the upper printing plate 12 and the back surface 12A of the lower printing plate 12 for protecting the photosensitive layer. Each time the printing plate 12 is taken out of the packing box 38 as will be described later, the slip sheet 48 is removed by a slip sheet removing mechanism (not shown).
[0039]
Further, a cut line 50 as a “cutting portion” is provided at each root portion of the pair of unpacking portions 38A1 and 38A2 constituting the upper surface 38A of the packaging box 38 described above. Accordingly, each unpacking portion 38A1, 38A2 can be cut along the cut line 50. The packaging box 38 in which the pair of unpacking portions 38A1 and 38A2 is cut out in this way and the upper surface 38A side is opened can be directly loaded into the accommodation unit 40 of the plate feeding portion 15 of the printing plate automatic exposure apparatus 10. . In other words, in the present embodiment, the packing box 38 from which the upper surface 38A has been cut off functions as a conventional cassette.
[0040]
Next, the operation and effect of this embodiment will be described.
[0041]
The unused printing plate 12 is stored in the packing box 38 alternately with a predetermined number of sheets 48. At this time, the printing plate 12 is stored in the packing box 38 so that the photosensitive surface 12B faces downward. After the printing plate 12 is accommodated in the packing box 38 in a stacked state, the pair of unpacking portions 38A1 and 38A2 are closed, and an adhesive tape 46 such as a gum tape is applied to the joint of both. Thereby, the packing operation of the printing plate 12 into the packing box 38 is completed, and the printing plate 12 is shipped from the manufacturing factory of the printing plate 12 to the factory that performs the exposure processing of the printing plate 12 by the transport vehicle.
[0042]
In a factory where exposure processing or the like is performed, first, unpacking work of the packing box 38 is performed. Specifically, it is cut along a tear line 50 provided at the base portion of the pair of unpacking portions 38A1 and 38A2 on the upper surface 38A of the packing box 38. After cutting, both ends of the adhesive tape 46 are peeled off (note that both ends may be cut). Thereby, as shown in FIG. 1B, the upper surface 38A of the packing box 38 is separated from the packing box 38, and the back surface 12A of the printing plate 12 appears.
[0043]
Next, in this state, the packing box 38 is loaded into the accommodation unit 40 of the plate feeding unit 15 of the printing plate automatic exposure apparatus 10. That is, the packing box 38 from which the upper surface 38A is separated is directly loaded into the accommodation unit 40 instead of the cassette.
[0044]
Thereafter, the printing plate automatic exposure apparatus 10 is operated. In general, as shown in FIG. 3, first, the drawer 52 and the moving table 56 are moved up and down to a position corresponding to the packing box 38 in which the printing plate 12 of the target size is accommodated. Next, after the arm portion 54 of the drawer portion 52 is extended to move the suction plate 53 to a predetermined pickup position, the suction plate 53 is lowered and brought into contact with the upper surface of the end portion of the printing plate 12. Next, suction by the suction plate 53 is started, and the upper surface of the end portion of the uppermost printing plate 12 is sucked by the suction plate 53. Next, the drawing portion 52 is operated in the reverse direction to hold the leading end portion of the printing plate 12 between the pair of nip rollers 58. The pair of nip rollers 58 are rotated by a predetermined amount, and the leading end of the printing plate 12 is once fed to the left side in the figure. Then, when the rear end of the printing plate 12 reaches between the nip rollers 58, the rotation is stopped, and the moving table 56 is raised to a position corresponding to the transport guide unit 18 of the exposure unit 14 as shown in FIG. In this state, the leading end portion of the printing plate 12 is in a state of hanging from the moving table 56. Next, as shown in FIG. 5, the pair of arms 60 of the moving table 56 are rotated (reversed) in the direction of the arrow by 180 degrees. Accordingly, the nip roller 58 is positioned on the entrance side of the conveyance guide unit 18.
[0045]
Thereafter, the nip roller 58 is reversed, whereby the printing plate 12 is fed from the rear end portion to the conveyance guide unit 18 of the exposure unit 14. In this state, since the plate feed guide 20 corresponds to the puncher 24, the printing plate 12 is sent to the puncher 24 and a predetermined punching process is performed. When this operation is completed, the printing plate 12 is once returned to the plate supply guide 20 and the conveyance guide unit 18 is rotated so that the outlet side thereof is positioned in the tangential direction of the rotary drum 16.
[0046]
The printing plate 12 fed from the conveyance guide unit 18 is tightly wound around the outer peripheral surface of the rotary drum 16 by the front end chuck 26 and the rear end chuck 36. Thereby, the positioning of the printing plate 12 for exposure with respect to the rotary drum 16 is completed. Thereafter, image data is read, and exposure processing is started by the light beam from the recording head unit 37. The exposure process is performed by a so-called scanning exposure method in which the recording head unit 37 is moved in the axial direction of the rotating drum 16 while rotating the rotating drum 16 at high speed (main scanning).
[0047]
When the exposure processing is completed as described above, the conveyance guide unit 18 is switched (that is, the plate discharge guide 22 is made to correspond to the outer peripheral surface of the rotary drum 16), and the rotary drum 16 is removed from the printing plate 12 (in the direction of arrow B). ). As a result, the printing plate 12 wound around the outer peripheral surface of the rotary drum 16 is discharged while being guided by the plate discharge guide 22. A developing unit (not shown) is provided on the discharge direction side of the plate discharge guide 22, and the discharged printing plate 12 is continuously developed by the developing unit.
[0048]
As described above, in the packaging box 38 according to the present embodiment, the cut line 50 is provided on the upper surface 38A so that the upper surface 38A can be cut and separated from the packaging box 38 when unpacking, and the printing plate can be obtained by removing the upper surface 38A. Since the 12 back surfaces 12A always appear, and the packing box 38 in this state is directly loaded into the storage unit 40 of the plate feeding unit 15 of the printing plate automatic exposure apparatus 10, it has been conventionally performed. There is no need to refill the printing plate 12 from the packaging box to the cassette, and the photosensitive surface 12B of the printing plate 12 is not damaged when the refilling operation is performed.
[0049]
Moreover, in the packing box 38 according to the present embodiment, a configuration in which the packing box 38 is directly loaded into the accommodation unit 40 of the plate feeding unit 15 of the printing plate automatic exposure apparatus 10, that is, a configuration in which the packing box 38 is used instead of a conventional cassette. Therefore, the work of refilling the printing plate 12 from the packing box to the cassette as in the prior art becomes unnecessary. Accordingly, it is possible to reduce the work effort of the worker.
[0050]
Furthermore, since the packaging box 38 according to the present embodiment does not require a cassette as described above, significant cost reduction can be achieved.
[0051]
Generally speaking, according to the packing box 38 according to the present embodiment, the cut packing box 38 can be directly loaded into the storage unit 40 instead of the cassette. As a result, it is possible to reliably prevent the photosensitive surface 12B of the printing plate 12 from being damaged, to reduce the work effort of the operator, and to obtain a significant cost reduction effect.
[0052]
