Description

The present invention relates to machining line of a planographic printing plate.

  A lithographic printing plate (hereinafter referred to as “PS plate”) is generally subjected to surface treatment such as graining, anodic oxidation, silicate treatment, and other chemical conversion treatments on a metal plate such as a sheet-shaped or coil-shaped aluminum plate alone or as appropriate. Next, after applying the photosensitive solution and drying treatment, it is cut into a desired size by the cutting unit, collected from the sheet state into a bundle state, packaged in a product form and shipped.

  However, PS plates are limited to photosensitive printing plates, but there are varieties such as small printing, large printing, newspaper printing, and laser plate making, and the plate thickness is 0.1 mm to 0.5 mm. Also, the size ranges from card size to tatami size, and is supplied to users according to each specification.

  Here, the shipment form according to each specification consists of a form in which a bundle of sheets is shipped with an interior material such as aluminum craft, with an equivalent of 20 kg per bundle as a guide, and an interior bundle bundled internally. Most of them are called individual packaging (corrugated cardboard packaging) that is packaged with a flat cardboard box (for example, Patent Document 1).

  On the other hand, with the widespread use of photosensitive printing plates, the usability of users has diversified, and bundled interior forms in which several bundles of interior bundles are stacked and shipped in pallet packaging, bulk forms in which hundreds of pallets are packaged together without interior decoration, Various shipping forms such as a skid form in which hundreds of sheets are stacked and packaged in a special iron skid without paper have been required.

  When performing individual packaging only, after cutting the PS plate to a desired size, it is possible to equip an automatic line relatively easily by directly connecting a packaging device for interior or individual packaging to the rear end of the cutting part. In order to correspond to the various shipping modes mentioned above, it is difficult to make an automatic line equipment. PS plates cut by the cutting section are once stacked on a pallet and stored, and sorted according to the shipping form. The PS plate must be removed and packaged manually.

Here, as an automation measure, it is possible to arrange various packaging devices in parallel at the rear end of the cutting part. However, when packaging in the specified form, other packaging devices become inactive and inefficient. It is.

  FIG. 1 shows a processing line 100 of a lithographic printing plate 10 (hereinafter referred to as “PS plate 10”) to which a packaging method according to an embodiment of the present invention is applied.

  On the upstream side (upper right side in FIG. 1) of the processing line 100, a feeder 14 for sequentially unwinding the web 12 previously wound in a roll shape is disposed. The long web 12 delivered from the delivery machine 14 is subjected to curl correction, and then an interleaf paper 18 is pasted together and brought into close contact by charging to reach the notch 20.

  The notch 20 is provided with a punched portion on the web 12 so that the cutting blade 24 constituting the cutting processing portion 22 can move in the width direction of the web 12 at the punching position. This makes it possible to change the cutting width of the web 12 while continuously cutting the web 12.

  In this way, the web 12 cut to a predetermined cutting width is cut by the running cutter 30 at the instructed timing. Thereby, the PS plate 10 having the set size is manufactured. Each PS plate 10 individually has information such as size and shipping form, and is controlled by the control unit 32 (see FIG. 2) according to the shipping form (described later).

  Then, the PS plate 10 is sent to a packaging step 36 described later by the conveyor 34, and is packed with a packaging material (tape, interior material, exterior material, etc.) according to each shipment form, and shipped to each user.

  Here, the web 12 has a photosensitive layer (or heat-sensitive layer) formed in advance on an aluminum support, and the surface on which the photosensitive layer (or heat-sensitive layer) is formed is the PS plate 10 (FIG. 1). Reference image forming surface (the surface of the web 12). The web 12 is processed by the processing line 100 to have a desired size, so that the PS plate 10 usable for printing is obtained.

  The aluminum plate as the support is, for example, JIS 1050 material, JIS 1100 material, JIS 1070 material, Al—Mg alloy, Al—Mn alloy, Al—Mn—Mg alloy, Al—Zr alloy, Al—Mg. -Si-based alloys and the like can be applied. In the manufacturing process of an aluminum plate at a manufacturer, an aluminum ingot that conforms to the above-mentioned standard is manufactured, the aluminum ingot is hot-rolled, and then subjected to a heat treatment called annealing, if necessary, by cold rolling. Finished with a strip-shaped aluminum plate.

  The PS plate 10 is formed by applying a coating film (a photosensitive layer in the case of a photosensitive printing plate, a thermal layer in the case of a thermal printing plate) on one side of a thin aluminum plate formed in a rectangular plate shape. Has been. The coating film is subjected to plate making processing such as exposure, development processing, and gumming, and is set in a printing machine, and ink is applied to print characters, images, and the like on the paper surface.

  The specific configuration of the PS plate 10 (web 12) is not particularly limited. For example, a lithographic printing plate that can be directly made from digital data by using a lithographic printing plate for a laser printing plate of a heat mode method and a photon method. It can be a version.

  The surface coated with the coating film is referred to as an image forming surface, and the opposite surface, that is, the surface not coated with the coating film is referred to as a non-image forming surface. Note that the PS plate 10 of the present embodiment is a stage before processing necessary for printing (exposure, development, etc.) and is sometimes referred to as a lithographic printing plate precursor or a lithographic printing plate material. There is also.

The PS plate 10 can be a lithographic printing plate corresponding to various plate making methods by selecting various components in the photosensitive layer or the heat sensitive layer. Examples of specific embodiments of the lithographic printing plate of the present invention include the following embodiments (1) to (11).
(1) An embodiment in which the photosensitive layer contains an infrared absorber, a compound that generates an acid by heat, and a compound that crosslinks by an acid.
(2) An embodiment in which the photosensitive layer contains an infrared absorber and a compound that becomes alkali-soluble by heat.
(3) A mode in which the photosensitive layer includes two layers of a compound that generates radicals upon irradiation with laser light, a layer containing an alkali-soluble binder, and a polyfunctional monomer or prepolymer, and an oxygen blocking layer.
(4) An embodiment in which the photosensitive layer is composed of two layers of a physical development nucleus layer and a silver halide emulsion layer.
(5) A mode in which the photosensitive layer includes three layers of a polymerization layer containing a polyfunctional monomer and a polyfunctional binder, a layer containing silver halide and a reducing agent, and an oxygen blocking layer.
(6) A mode in which the photosensitive layer includes two layers of a layer containing a novolac resin and naphthoquinone diazide and a layer containing silver halide.
(7) A mode in which the photosensitive layer contains an organic photoconductor.
(8) A mode in which the photosensitive layer includes 2 to 3 layers including a laser light absorbing layer to be removed by laser light irradiation, and a lipophilic layer and / or a hydrophilic layer.
(9) A compound in which the photosensitive layer absorbs energy to generate an acid, a polymer compound having a functional group that generates sulfonic acid or carboxylic acid by an acid in the side chain, and an acid generator by absorbing visible light The aspect containing the compound which gives energy to.
(10) The mode in which the photosensitive layer contains a quinonediazide compound and a novolac resin.
(11) A mode in which the photosensitive layer contains a compound that decomposes by light or ultraviolet rays to form a crosslinked structure with itself or other molecules in the layer and an alkali-soluble binder.

  In particular, in a lithographic printing plate having a photosensitive layer (or heat-sensitive layer) whose solubility in a developing solution is changed by irradiation with laser light, the photosensitive layer (or heat-sensitive layer) is easily damaged, and therefore the lithographic printing plate packaging structure of the present invention Is preferable because it can surely prevent so-called film peeling as described later.

In addition, the wavelength of the laser beam here is not particularly limited. For example,
(A) A laser having a wavelength range of 350 to 450 nm (as a specific example, a laser diode having a wavelength of 405 ± 5 nm).
(B) A laser having a wavelength range of 480 to 540 nm (specific examples are an argon laser having a wavelength of 488 nm, a (FD) YAG laser having a wavelength of 532 nm, a solid laser having a wavelength of 532 nm, and a (green) He—Ne laser having a wavelength of 532 nm).
(C) A laser having a wavelength range of 630 to 680 nm (specific examples are a He—Ne laser having a wavelength of 630 to 670 nm and a red semiconductor laser having a wavelength of 630 to 670 nm).
(D) A laser having a wavelength range of 800 to 830 nm (as a specific example, an infrared (semiconductor) laser having a wavelength of 830 nm).
(E) A laser having a wavelength of 1064 to 1080 nm (specifically, a YAG laser having a wavelength of 1064 nm).

  Etc. Among these, for example, both of the laser beams in the wavelength regions (b) and (c) can be applied to both the lithographic printing plate having the photosensitive layer or the heat-sensitive layer of the above-described aspect (3) or (4). It is. Further, both of the laser beams in the wavelength ranges of (d) and (e) can be applied to both the lithographic printing plates having the photosensitive layer or the heat-sensitive layer of the above-described aspect (1) or (2). Of course, the relationship between the wavelength range of the laser beam and the photosensitive layer or the heat-sensitive layer is not limited thereto.

  The shape or the like of the PS plate 10 is not particularly limited. For example, the photosensitive layer or the surface of one side of an aluminum plate having a thickness of 0.1 to 0.5 mm, a long side (width) of 300 to 2050 mm, and a short side (length) of 200 to 1500 mm is used. The heat sensitive layer may be applied.

  The interleaf paper 18 used may be a general one used for a lithographic printing plate, but typical examples are shown below. The specific configuration of the interleaf paper 18 is not limited as long as the coating film of the PS plate 10 can be reliably protected. For example, paper using 100% wood pulp or synthetic pulp without using 100% wood pulp is used. The paper used, and paper with a low density polyethylene layer provided on the surface of these papers can be used.

In particular, paper that does not use synthetic pulp reduces the material cost, so that the interleaf paper 18 can be manufactured at low cost. More specifically, basis weight 20-55 g / m ² made from bleached kraft pulp, density 0.7-0.85 g / cm ³ , moisture 4-6%, Beck smoothness 10-800 seconds, PH 4-6 A slip sheet having an air permeability of 15 to 300 sec can be mentioned, but the present invention is not limited to this.

  Next, the packaging process 36 according to the embodiment of the present invention will be described.

  As shown in FIGS. 1 and 2, the packaging process 36 includes a stacking unit 38, a bundle tape unit 40, a bundle interior unit 42, an exterior unit 44, a first shipping unit 46, a bundle accumulation unit 47, a batch interior unit 48, a piece. It is composed of a corrugated cardboard exterior portion 50, a top plate mounting portion 52, a band fastening portion 54, and a second shipping portion 56, which are arranged on a single line.

First, each step will be described below with reference to FIGS. 1 and 2.
(Accumulator 38)
As shown in (A) of FIGS. 3 (i) and (ii), a predetermined number of PS plates 10 are stacked in the stacking unit 38 (so-called stacked bundle 60). The number of PS plates 10 constituting one stacked bundle 60 is not particularly limited, but may be, for example, 10 to 100 sheets from the viewpoint of efficient transportation and storage. It is also possible to configure the laminated bundle 60 with a larger number of PS plates 10 so that it can be transported and stored more efficiently (with a smaller number of times of cargo handling).

  For example, the maximum number of PS plates 10 may be about 3000. Depending on the type of the PS plate 10, the interleaf sheet 18 that protects the coating film may be omitted, and the stacked bundle 60 may be configured by the PS plate 10 alone. In addition, the stacked bundle 60 may be directly stacked on the pallet 41 in the stacking unit 38.

  Here, each PS plate 10 has an information unit 160 in which information such as a size and a shipping form is individually recorded. The information unit 160 is read by a reader 162 arranged on the processing line 100. Information such as the recorded shipping form is read and a signal is transmitted to the control unit 32.

  As a result, in the stacking unit 38, in a state where a predetermined number of PS plates 10 are stacked (stacked bundle 60), the process of the bundled interior unit 42, the exterior unit 44, etc. selected by the control unit 32 according to the information in the information unit 160 The stacked bundle 60 moves to the bottom. Here, the stacking unit 38 is provided at one place, but a plurality of places may be provided.

  Next, as shown in FIGS. 3 (i) and (ii) (B), protective cardboard 62 (a so-called hitting ball 62, hereinafter referred to as a hitting ball 62) is provided on the upper and lower sides or one side of the laminated bundle 60. ) Is arranged. The contact ball 62 is cut in advance according to the size of the stacked bundle 60 in the cutting section 39 disposed in the vicinity of the stacking section 38 and supplied to the stacking section 38. The contact balls 62 prevent the PS plate 10 constituting the stacked bundle 60 from being bent, deformed or damaged by an external force.

Here, depending on the type of the PS plate 10, there is one (so-called “double-sided product”) in which a coating film is provided on both sides as well as one side. As the batting ball 62, a basis weight of 200-1500 g / m using a natural pulp such as wood pulp, hemp or the like, a synthetic pulp obtained from a linear polymer such as polyolefin, a regenerated cellulose or the like alone or a mixture thereof is used. ² , a paper having a density of 0.7 to 0.85 g / cm ³ , a moisture content of 4 to 6%, a Beck smoothness of 3 to 20 seconds, and a pH of 4 to 6 can be used, but is not limited thereto.

In particular, by selecting a low-cost material such as wood pulp or natural fiber fiber, the contact ball 62 can be manufactured at a low cost. More specifically, for example, raw material waste paper is beaten, and the sizing agent is 0.1% of the cardboard weight and the paper strength agent is 0.2% of the cardboard weight in the paper stock diluted to a concentration of 4%. In addition, there may be mentioned thick paper having a density of 0.72 g / cm ³ and a basis weight of 640 g / m ² obtained by making paper using a paper material in which aluminum sulfate is added until the pH becomes 5.0. Of course, it is not limited to this.
(Bundle tape section 40)
As described above, in the state where the contact balls 62 are arranged above and below the stacked bundle 60 (hereinafter referred to as “stacked bundle 64”), as shown in FIG. The adhesive tape (hereinafter referred to as “bundled tape 66”) is attached at a predetermined position. Thereby, it fixes so that the lamination | stacking bundle | flux 64 may not spread carelessly.
(Bundle interior part 42)
Next, as shown in (D) of FIGS. 3 (i) and (ii), regardless of the presence or absence of the bundle tape 66, the laminated bundle 64 is decorated with the interior paper 68 in the bundle interior portion 42 (interior). Hereinafter, the laminated bundle 64 that has been decorated with the paper 68 is referred to as an “interior bundle 74”. The interior paper 68 is made of a light-shielding and moisture-proof paper, and the interior paper 68 is used so that the interior of the laminated bundle 64 is completely blocked from the outside, so that the laminated bundle 64 can be secured. It can be shielded from light and moisture.

  The material of the interior paper 68 is not particularly limited as long as the laminated bundle 64 can be completely cut off from the outside and packaged as described above. For example, a single rectangular unexposed sheet having a predetermined size can be used. Can be composed of kraft paper.

  Here, as shown in FIG. 5A, the length of the long side 68L of the interior paper 68 is such that the long side 64L of the laminated bundle 64 and the short side 68S of the interior paper 68 are parallel to each other. In the state where the laminated bundle 64 is placed in the approximate center and the interior paper 68 is bent from both sides along the long side 64L of the laminated bundle 64, the vicinity of the short side 68S of the interior paper 68 is partially overlapped. .

  Further, as shown in FIG. 5B, the length of the short side 68S of the interior paper 68 is further folded on the long side 68L side of the interior paper 68 from the state where the vicinity of the short side 68S partially overlaps. When collapsed, the length is such that it partially overlaps the top surface of the stack 64 in plan view.

  In this way, by interiorizing the laminated bundle 64 with the interior paper 68, as shown in FIG. 5C, the laminated bundle 64 is covered with the interior paper 68 over the entire surface. Here, one end portion of the interior paper 68 positioned above in an overlapped state is glued with hot melt or the like, and is pasted at a predetermined position of the interior paper 68, and the interior paper 68 is inadvertently spread or dropped. Fix it so that it does not go. Heat sealing or tape fastening may be used instead of gluing.

5A to 5C is an example of a structure in which the laminated bundle 64 is housed by the interior paper 68, and it is needless to say that the present invention is not limited to this. In short, it is only necessary to cover the laminated bundle 64 with the interior paper 68 so that the PS plate 10 can be reliably shielded from light and moisture proof by being combined with the exterior material 70 as described later.
(Exterior part 44)
As shown in FIGS. 3 (i), (ii) (D) and FIG. 6, the exterior material 70 is made of cardboard, and is a cardboard box having an internal dimension capable of accommodating one or a plurality of interior bundles 74. ing. Therefore, in a state in which the interior bundle 74 is accommodated inside the exterior material 70, cardboard is arranged around the interior bundle 74, and even if an object hits from the outside during transportation or storage, This energy is absorbed by the exterior material 70.

Further, light from the outside of the exterior material 70 is blocked by the exterior material 70, and light reaching the interior paper 68 is extremely weak (substantially only light incident from a bonded portion of the exterior material 70 or the like). Furthermore, the exterior material 70 acts as a buffer against humidity changes and temperature changes outside the exterior material 70, and humidity changes and temperature changes inside the exterior material 70 are smaller than those outside.
(First shipping part 46)
In the first shipping unit 46, as described above, the interior bundle 74 that is exteriorized with the exterior material 70 is shipped to the user as one of the shipping modes.
(Bundle stacking unit 47)
On the other hand, as shown in (A) of FIG. 4 (i), the interior bundle 74 that is decorated with the interior paper 68 is stacked on a pallet 82 (hereinafter referred to as “stacked bundle 78”). The interior is packaged.
(Batch interior part 48)
Next, in the collective interior portion 48, as shown in FIGS. 4 (i) to (iv) (B), the integrated bundle 78 or the stacked bundle 64 is collectively integrated. Hereinafter, the stacking bundle 78 will be described as an example. As shown in FIG. 7, one end of the inner paper 80 is held in contact with the side surface of the stacked bundle 78, the turntable 102 on which the pallet 82 is placed is turned, and the inner paper 80 is moved to the side surface of the stacked bundle 78. Wrap around. At this time, the craft tape 84 is wound around the lower end portion of the interior paper 80 and the side surface of the stacking member 86, and the lower end portion of the interior paper 80 is bonded to the side surface of the stacking member 86. Alternatively, a double-sided tape may be attached to the lower part of the interior paper and bonded to the side surface of the stacking member 86.

  The interior paper 80 uses aluminum kraft paper in which aluminum foil is laminated on kraft paper for the purpose of ensuring light shielding and moisture proofing. A low density polyethylene layer or a black polyethylene film laminated on an aluminum foil is used.

Here, the width of the interior paper 80 exceeds the height of the stacking bundle 78, and is sized so that the upper portion of the stacking bundle 78 can be covered by folding the portion beyond the height of the stacking bundle 78 later. As shown in FIGS. 8A and 8B, when the interior paper 80 is wound once around the side surface of the bundle of bundles 78, the interior paper 80 is cut and the rear end portion and the front end portion thereof are tape 81 or hot. Adhere with an adhesive such as melt. Then, the upper part is folded to cover the upper surface of the bundle of bundles 78 and taped. The integrated bundle 78 that is collectively packaged in this way is hereinafter referred to as a packaged bundle 92.
(Single cardboard batch exterior 50)
Next, depending on the shipment form, as shown in FIGS. 4 (i) and (ii) (C), a single cardboard batch exterior is performed. That is, as shown in FIG. 9, a so-called single cardboard 94 is pulled out from the single cardboard roll 98 and wound around the side surface of the batch interior bundle 92 by the winding device 96.

  The wrapping device 96 is provided with a circular turntable 102 on which a pallet 82 on which a batch of inner bundles 92 is loaded is placed and swiveled clockwise (in the direction of arrow A in the figure) by a swiveling device (not shown). . On the turntable 102, a first tip holding device 104 that holds the tip of the corrugated cardboard 94 is erected with a gap from the side surface of the batch interior bundle 92.

  The first tip holding device 104 is a hollow rectangular columnar chamber, the inside of which is evacuated by a vacuum device (not shown), and a plurality of suction holes (not shown) are formed on the surface facing the side surface of the batch interior bundle 92. . As a result, the tip of the single cardboard 94 can be adsorbed, and when the turntable 102 is turned, the single cardboard 94 is unwound from the single cardboard roll 98 and wound around the side surface of the batch interior bundle 92.

  Further, there is provided a slack eliminating device 106 for bringing the corrugated cardboard 94 into close contact with the side surface of the collective interior bundle 92 when the turntable 102 is being swung to remove the slack of the wound corrugated cardboard 94.

  The slack eliminating device 106 includes a slack eliminating roll 108 and a U-shaped arm 110 that rotatably supports both ends in the axial direction of the slack eliminating roll 108, and the shaft portion 110A is supported by an air cylinder (not shown). The slack eliminating roll 108 is pressed against the side surface of the batch interior bundle 92.

Then, when the turntable 102 is turned once and the single cardboard 94 is wound around the side surface of the batch interior bundle 92, the second tip holding device 112 holds the single cardboard 94. Here, the cutting and holding device 114 cuts the single cardboard 94 and affixes it to the side surface of the batch interior bundle 92 with an adhesive such as tape or hot melt.
(Top plate mounting part 52)
Next, regardless of the presence or absence of the single-cardboard collective exterior, the collective interior bundle 92 drives the moving device 120 (see FIG. 10) as shown in (D) of FIGS. 4 (i) to (iv), The top plate 116 corresponding to the collective interior bundle 92 is transferred to the top surface of the collective interior bundle 92.

Here, as illustrated in FIG. 10, the moving device 120 is provided with a suction pad 122, and the top plate 116 is sucked by the suction pad 122 and moved above the batch interior bundle 92. The top plate 116 is formed in a plate shape having a size substantially the same as or slightly larger than the top surface of the collective interior bundle 92 depending on the size of the collective interior bundle 92. Even when an external force is applied from above, the energy is absorbed, and the deformation of the PS plate 10 is suppressed to such an extent that it does not cause a practical problem.
(Band fastening part 54)
Next, in the band fastening portion 54, as shown in FIGS. 4 (i) to (iv) (E) and FIG. 11, the whole of the pallet 82, the batch interior bundle 92 and the top plate 116 are integrated. A band 124 formed of a resin band is wound around the pallet 82, so that the pallet 82, the batch interior bundle 92, and the top plate 116 can be handled in an integrated manner. (Hereinafter, referred to as “bundled bundle 126”).
(Second shipping part 56)
In the second shipping unit 56, as described above, the bundled bundle 126 that has been band-fastened is shipped to the user as one of shipping modes.

  Next, the gist of the packaging method according to the embodiment of the present invention will be described.

  FIG. 2 schematically shows a line of the packaging process 36, and six types of shipping forms are shown as an example.

  For example, the shipping forms I and II are so-called bundled interior forms, and after the exterior part 44 is used for the exterior packaging with the exterior material 70 (so-called bundled interior forms, see FIGS. 3 (i) and (ii) (E)). ), Sent to the first shipping section 46 and shipped.

  Here, in the shipment form I, processing in each step of the stacking unit 38, the bundle tape unit 40, the bundle interior unit 42, and the exterior unit 44 (see (A) to (E) of FIG. 3I) is performed. In the shipping form II, the PS plate is accumulated, and the laminated bundle 64 is passed through the bundle tape portion 40 with the ball 62 disposed on the laminated bundle 60 and without the bundle tape 66, and the laminated bundle portion 64 is bundled. The bundle interior and exterior are performed (see (A) to (E) of FIG. 3 (ii)).

  Moreover, although the shipment forms III-VI are sent to the 2nd shipment part 56, these will pass the exterior part 44. FIG. For example, in the shipment form III, the interior bundle 74 (see (D) in FIG. 3 (i)) installed in the bundle interior portion 42 is bundled by the bundle accumulation portion 47 and passes through the collective interior portion 48. In the single cardboard collective exterior portion 50, a single cardboard collective package is formed (see (A) to (C) of FIG. 4 (i)). Then, the top plate 116 is placed on the top plate mounting part 52, and the band fastening part 54 is fastened to the band, and then sent to the second shipping part 56 (see (D) and (E) of FIG. 4 (i)). ).

  Here, the shipment form IV is substantially the same form as the shipment form III, but in the shipment form IV, the bundle tape 66 passes through the bundle tape portion 40 in a state where the contact balls 62 are arranged on the laminated bundle 60. The bundled interior is performed in a state where it is not performed (see (A) to (D) of FIG. 3 (ii)).

On the other hand, in the shipment forms V and VI, the PS plates are collected and passed through the bundle tape portion 40, the bundle interior portion 42, the exterior portion 44, and the bundle accumulation portion 47 in a state where the ball 62 is disposed on the laminated bundle 60. Then, the collective interior is formed by the collective interior portion 48 (see (A) and (B) of FIGS. 4 (ii) to (iv)).

The shipping form V includes a single cardboard batch exterior portion 50, a top plate mounting portion 52, and a band fastening portion 5
4, each process is performed (so-called bulk form, see (C) to (E) in FIG. 4 (ii)). In addition, in the shipment form VI, after the collective interior is formed by the collective interior part 48, it passes through the single cardboard collective exterior part 50 and is sent to the top plate mounting part 52 (so-called skid form, FIG. 4 (iii), ( (See (C) to (E) of iv)).

  Thus, the packaging process 36 (a cutting process part 22, the accumulation part 38, the bundle interior part 42, the exterior part 44, the 1st shipment part 46, the bundle accumulation part 47, the batch interior part 48, a piece provided with the several shipment form. Since the cardboard batch exterior portion 50, the top plate mounting portion 52, the band fastening portion 54, and the second shipping portion 56) are arranged on a single line, it is only necessary to pass the PS plate 10 in unnecessary steps. Since it is not necessary to store in accordance with the shipping form, and the line can be configured in synchronization with the processing step for processing the web 12 and the packaging step 36, the production efficiency is increased.

  In addition, by arranging the packaging process 36 on a single line, it is possible to completely automate the production process from the production of the PS plate 10 to the shipment in the processing line 100 of the PS plate 10.

  For example, as described above, information on the information section 160 (for example, barcode printing is performed by inkjet marking or the like) in which the size, the shipping form, and the display are individually recorded on each PS plate 10 is processed on the processing line 100. Reading is performed by the arranged reading device 162, and a signal is transmitted to the control unit 32.

  Then, the control unit 32 moves the PS plate 10 to a process such as the bundled interior part 42, the exterior part 44, and the bundle accumulation part 47 selected according to the information in the information part 160, thereby changing the shipping form. In contrast, the switching can be performed smoothly.

  That is, since the position of the predetermined PS plate 10 can be grasped by tracking in a controlled manner, after the packaging in the predetermined shipping form is completed, immediately after the line of the packaging process 36 is finished, the next shipping form It is possible to shift to the packaging process 36 line.

  Here, the information in the information unit 160 in which the size, shipping form, display, and the like are individually recorded is read by the reading device 162, but the present invention is not limited to this. For example, each PS plate 10 may be controlled by the control unit 32 as virtual data, and the consistency may be confirmed based on the final shipment volume information.

  By the way, as described above, in arranging the packaging process 36 on a single line, at least a part of the packaging form such as the interior and the exterior is unified in the so-called bundled interior form, bulk form, skid form and the like. It has become.

  That is, as shown in FIG. 12 and FIG. 13, in the conventional packaging form, the packaging method differs depending on each shipping form. For example, the bulk form (see FIG. 12 (i)) and the skid form (see FIG. 12). 12 (ii), (iii)) is obvious when compared.

  In the bulk form (see FIG. 12 (i)), as shown by the line 2 in VI of FIG. 13, after the collective interior A, the square cushioning material 130 and the sleeve 132 are respectively extrapolated (collective exterior B), A top plate 134 is placed and band fastening is performed.

On the other hand, in the skid configuration (see FIG. 12 (ii)), as indicated by the line V in FIG.
The interior paper 138 is placed so as to cover the upper surface and the side surface of the laminated bundle 64 from the upper part of the laminated bundle 64 that has been bundled. Then, the tape is taped in a state where the inner paper 138 is pressed with a pair of U-shaped corrugated cardboards 140 having a seam in the width direction (collective interior B), and the outer periphery is wound with a stretch member 142 (collective exterior C). A top plate 146 is placed on the upper surface of the bundle 144, and the top plate 146 is fastened with a tape 147 (stretch fastening).

  Further, in another skid configuration (see FIG. 12 (iii)), as shown by line 1 in VI of FIG. 13, the upper surface and the side surface of the stacked bundle 64 are covered from the upper portion of the stacked stack 64. Cover the inner paper 148 and tap the inner paper 148 while holding the inner paper 148 with a pair of U-shaped cardboards 150 having a seam in the longitudinal direction (collective interior C). A top plate 154 is placed and bolts are fastened.

  Further, in the case of shipping after bundled packaging, as shown by the lines I to IV in FIG. 13, after bundled packaging, it is shipped in two types of forms, cardboard exterior and collective exterior A, although not shown. The Rukoto.

  Thus, conventionally, since the packaging method differs according to each shipping form, the materials used for each shipping form also differ. For this reason, as shown in FIG. 13, in the conventional packaging process 156, a line cannot be unified but a several line is needed according to each shipment form. Accordingly, each material is stored according to the shipment form.

  However, as in the present invention, in each shipping form, by unifying at least a part of the packaging form such as the interior and the exterior, it becomes possible to share materials and to realize space saving. . Furthermore, the operating rate of the packaging process 36 can be increased, and the devices disposed in each process are not wasted.

  In addition, when processing must be performed in a dark place under a red light such as a photopoly laser writing type or a silver salt type laser writing type, it is possible to easily switch the illumination because the operation is synchronized by eliminating storage. .
