1.1.2.1. 印刷属性判定部
印刷属性判定部122は、印刷情報から印刷属性を判定する処理を行う。具体的には、印刷属性判定部122は、印刷情報が入力されると以下の処理を開始する。以下では、入力される印刷情報のファイル形式がビットマップである場合について説明する。なお、入力される印刷情報のファイル形式は、特に限定されず、例えばページ記述言語(例えばPostscript)などであってもよい。 1.1.2.1. Print Attribute Determination Unit The printattribute determination unit 122 performs processing of determining the print attribute from the print information. Specifically, when the print information is input, the print attribute determination unit 122 starts the following process. The following describes the case where the file format of the input print information is a bitmap. The file format of the print information to be input is not particularly limited, and may be, for example, a page description language (for example, Postscript).
印刷属性判定部122は、印刷情報から印刷属性を判定する処理を行う。具体的には、印刷属性判定部122は、印刷情報が入力されると以下の処理を開始する。以下では、入力される印刷情報のファイル形式がビットマップである場合について説明する。なお、入力される印刷情報のファイル形式は、特に限定されず、例えばページ記述言語(例えばPostscript)などであってもよい。 1.1.2.1. Print Attribute Determination Unit The print
印刷属性判定部122は、まず、印刷情報に基づいて、矩形ブロックを生成する。具体的には、印刷属性判定部122は、印刷情報に含まれる画素を白黒に2値化して連結画素を検知し、黒画素輪郭で囲まれる画素塊を抽出する。さらに、印刷属性判定部122は、抽出された黒画素塊の大きさを評価し、大きさが所定値以上の黒画素塊の内部にある白画素塊に対する輪郭追跡を行う。そして、印刷属性判定部122は、白画素塊に対する大きさ評価、内部黒画素塊の追跡というように、内部の画素塊が所定値以上である限り、再帰的に内部画素塊の抽出、輪郭追跡を行う。印刷属性判定部122は、上記のようにして得られた画素塊に外接する矩形ブロックを生成する。画素塊の大きさは、例えば、画素塊の面積によって評価される。
The print attribute determination unit 122 first generates a rectangular block based on the print information. Specifically, the print attribute determination unit 122 binarizes the pixels included in the print information into black and white, detects connected pixels, and extracts a pixel block surrounded by black pixel outlines. Furthermore, the print attribute determination unit 122 evaluates the size of the extracted black pixel block, and performs contour tracking on the white pixel block inside the black pixel block having a size equal to or larger than a predetermined value. Then, as long as the internal pixel block is equal to or larger than a predetermined value, the print attribute determination unit 122 recursively extracts the internal pixel block, and performs outline tracking, as in the size evaluation for the white pixel block and the tracking of the internal black pixel block. I do. The print attribute determination unit 122 generates a rectangular block circumscribing the pixel block obtained as described above. The size of the pixel block is evaluated, for example, by the area of the pixel block.
印刷属性判定部122は、次に、印刷情報から印刷属性を判定する。具体的には、印刷属性判定部122は、生成された矩形ブロックの形状や大きさ等から、矩形ブロックごとに印刷属性を判定する。印刷属性には、例えば、「文字(TEXT)」、「線画(LINE)」、「図面(PICTURE)」、「表(TABLE)」、「写真(PHOTO)」の5種類がある。
Next, the print attribute determination unit 122 determines the print attribute from the print information. Specifically, the print attribute determination unit 122 determines the print attribute for each rectangular block from the shape, size, and the like of the generated rectangular block. There are five types of printing attributes, for example, “TEXT”, “LINE”, “PICTURE”, “TABLE”, and “PHOTO”.
印刷属性判定部122は、例えば、矩形ブロックの縦横比が1に近く、大きさが所定の範囲の矩形ブロックを文字相当ブロックとし、近接する文字相当ブロックが規則正しく整列しているときに、これらの文字相当ブロックをまとめて、「文字領域矩形ブロック」を生成する。印刷属性判定部122は、例えば、扁平な画素塊を備えた矩形ブロックを、「線画領域矩形ブロック」とする。印刷属性判定部122は、例えば、一定の大きさ以上で、かつ四角形の白色画素塊を整列よく内包する黒画素塊を備えた矩形ブロックを、「表領域矩形ブロック」とする。印刷属性判定部122は、例えば、不定形な画素塊が散在している矩形ブロックを、「図面領域矩形ブロック」とする。印刷属性判定部122は、例えば、上記のいずれの印刷属性にも該当せず、不定形な画素塊を備えた矩形ブロックを「写真領域矩形ブロック」とする。
For example, when the aspect ratio of the rectangular block is close to 1 and the rectangular block of a predetermined size range is a character equivalent block, the printing attribute determination unit 122 determines that adjacent character equivalent blocks are regularly aligned. Character equivalent blocks are put together to generate a "character area rectangular block". For example, the print attribute determination unit 122 sets a rectangular block including a flat pixel block as a “line drawing area rectangular block”. The print attribute determination unit 122 sets, for example, a rectangular block including a black pixel block having a predetermined size or more and including a square white pixel block in a well-aligned manner as a “table area rectangular block”. For example, the printing attribute determination unit 122 sets a rectangular block in which irregular pixel blocks are scattered as a “drawing area rectangular block”. For example, the print attribute determination unit 122 does not correspond to any of the above-described print attributes, and sets a rectangular block including an irregular pixel block as a “photograph area rectangular block”.
例えば、入力される印刷情報が図2に示すような像を印刷するための情報である場合、印刷属性判定部122は、図4に示すように、Block1を「図面領域矩形ブロック」(印刷属性:図面)、Block2を「文字領域矩形ブロック」(印刷属性:文字)、Block3を「写真領域矩形ブロック」(印刷属性:写真)として、3つの矩形ブロックを生成する。Block1は、インク受容層104の第1部分104aに対応し、Block2は、第2部分104bに対応し、Block3は、第3部分104cに対応する。
For example, when the input print information is information for printing an image as shown in FIG. 2, the print attribute determination unit 122 sets Block 1 to “drawing area rectangular block” (print attribute as shown in FIG. 4). Drawing: 3 blocks are generated with Block 2 as "character area rectangular block" (printing attribute: character) and Block 3 as "photo area rectangular block" (printing attribute: photo). Block 1 corresponds to the first portion 104 a of the ink receiving layer 104, Block 2 corresponds to the second portion 104 b, and Block 3 corresponds to the third portion 104 c.
印刷属性判定部122は、さらに、生成された矩形ブロックの座標を求める。具体的には、印刷属性判定部122は、矩形ブロックの対角線上に位置する頂点の座標を求める。図4に示す例では、印刷属性判定部122は、矩形ブロックの左上の頂点(図2に示す例では-X軸方向側であって+Y軸方向側の頂点)と、右下の頂点(図2に示す例では+X軸方向側であって-Y軸方向側の頂点)と、の座標を求める。図4に示すXL1~XL3、YL1~YL3、XR1~XR3、およびYR1~YR3は、印刷属性判定部122により求められた任意の数値である。
The print attribute determination unit 122 further obtains coordinates of the generated rectangular block. Specifically, the print attribute determination unit 122 obtains coordinates of vertices located on the diagonal of the rectangular block. In the example shown in FIG. 4, the print attribute determination unit 122 sets the upper left vertex of the rectangular block (the vertex in the example shown in FIG. 2 that is on the −X axis direction side and + Y axis direction side) and the lower right vertex In the example shown in 2, the coordinates of + vertex in the + X axis direction and the vertex in the −Y axis direction) are determined. XL1 to XL3, YL1 to YL3, XR1 to XR3, and YR1 to YR3 shown in FIG. 4 are arbitrary numerical values obtained by the print attribute determination unit 122.
なお、上記では、印刷属性判定部122が矩形ブロックを生成する例について説明したが、印刷属性判定部122が生成するブロックの形状は、特に限定されず、例えば像の形状に対応した形状(像を一回り大きくした形状)であってもよい。
Although the example in which the print attribute determination unit 122 generates a rectangular block has been described above, the shape of the block generated by the print attribute determination unit 122 is not particularly limited. For example, the shape corresponding to the shape of the image (image The shape may be one size larger than
1.1.2.2. 印刷率導出部
印刷率導出部124は、印刷属性判定部122が生成した各矩形ブロックに対して、印刷情報から印刷率を導出(算出)する処理を行う。印刷率はプリンターや複写機などで利用されている数値で、印刷用紙の面積に対する、印刷される文字等の像の積算面積の比率のことである。すなわち、印刷用紙の上にどれだけインクやトナーがのっているかを表す数値である。印刷率の算出方法の詳細については省略する。 1.1.2.2. Print Rate Derivation Unit The printratio derivation unit 124 performs processing for deriving (calculating) the print ratio from the print information for each rectangular block generated by the print attribute determination unit 122. The printing rate is a numerical value used in printers and copiers, and is the ratio of the integrated area of an image such as characters to be printed to the area of printing paper. That is, it is a numerical value indicating how much ink or toner is deposited on the printing paper. The details of the method of calculating the printing rate will be omitted.

処理部120は、印刷属性判定部122および印刷率導出部124の処理により、図4に示すような表を生成し、該表を表示部140に表示するための処理を行ってもよい。図4に示すCR1~CR3は、印刷率導出部124により算出された任意の数字である。表示部140は、処理部120の解析結果を表示する機能を有している。表示部140は、例えば、LCD(Liquid Crystal Display)、CRT(Cathode Ray Tube)等によって実現される。
The processing unit 120 may perform processing for generating a table as shown in FIG. 4 and displaying the table on the display unit 140 by the processing of the printing attribute determination unit 122 and the printing ratio deriving unit 124. CR 1 to CR 3 shown in FIG. 4 are arbitrary numbers calculated by the printing rate deriving unit 124. The display unit 140 has a function of displaying the analysis result of the processing unit 120. The display unit 140 is realized by, for example, a liquid crystal display (LCD), a cathode ray tube (CRT), or the like.
1.1.2.3. 受容層厚決定部
受容層厚決定部126は、基材102上に形成するインク受容層104の厚さを、印刷情報に基づいて決定する処理を行う。具体的には、受容層厚決定部126は、印刷属性判定部122において判定された印刷属性、および印刷率導出部124において算出された印刷率の少なくも一方に基づいて、矩形ブロックごとにインク受容層104の厚さを決定する。好ましくは、受容層厚決定部126は、印刷属性および印刷率の両方に基づいて、矩形ブロックごとにインク受容層104の厚さを決定する。 1.1.2.3. Receiving Layer Thickness Determination Unit The receiving layerthickness determination unit 126 performs processing of determining the thickness of the ink receiving layer 104 formed on the substrate 102 based on the print information. Specifically, the receptive layer thickness determination unit 126 determines the ink for each rectangular block based on at least one of the print attribute determined by the print attribute determination unit 122 and the print ratio calculated by the print ratio derivation unit 124. The thickness of the receptive layer 104 is determined. Preferably, the receptive layer thickness determination unit 126 determines the thickness of the ink receptive layer 104 for each rectangular block based on both the printing attribute and the printing rate.
受容層厚決定部126は、基材102上に形成するインク受容層104の厚さを、印刷情報に基づいて決定する処理を行う。具体的には、受容層厚決定部126は、印刷属性判定部122において判定された印刷属性、および印刷率導出部124において算出された印刷率の少なくも一方に基づいて、矩形ブロックごとにインク受容層104の厚さを決定する。好ましくは、受容層厚決定部126は、印刷属性および印刷率の両方に基づいて、矩形ブロックごとにインク受容層104の厚さを決定する。 1.1.2.3. Receiving Layer Thickness Determination Unit The receiving layer
受容層厚決定部126は、印刷属性判定部122において判定された印刷属性に基づいて、例えば、インク受容層104を形成する層の数を決定する。具体的には、受容層厚決定部126は、矩形ブロックの属性が「文字」の場合は層の数を「1」と決定し、属性が「線画」の場合は層の数を「2」と決定し、属性が「図面」の場合は層の数を「3」と決定し、属性が「表」の場合は層の数を「2」と決定し、属性が「写真」の場合は層の数を「3」と決定する。
The receptive layer thickness determination unit 126 determines, for example, the number of layers forming the ink receptive layer 104 based on the print attribute determined by the print attribute determination unit 122. Specifically, the receptive layer thickness determination unit 126 determines the number of layers as “1” when the attribute of the rectangular block is “character”, and “2” when the attribute is “line drawing”. If the attribute is “drawing”, the number of layers is determined to be “3”. If the attribute is “table”, the number of layers is determined to be “2”. If the attribute is “photo” Determine the number of layers as "3".
受容層厚決定部126は、印刷率導出部124において算出された印刷率に基づいて、例えば、インク受容層104を形成する層の数を決定する。具体的には、受容層厚決定部126は、矩形ブロックの印刷率が5%未満の場合は層の数を「1」と決定し、印刷率が5%以上10%未満の場合は層の数を「2」と決定し、印刷率が10%以上の場合は層の数を「3」と決定する。
The receptive layer thickness determining unit 126 determines, for example, the number of layers forming the ink receiving layer 104 based on the printing rate calculated by the printing rate deriving unit 124. Specifically, the receptive layer thickness determination unit 126 determines that the number of layers is “1” when the printing ratio of the rectangular block is less than 5%, and the printing layer ratio of the layers when the printing ratio is 5% or more and less than 10%. The number is determined to be “2”, and when the printing rate is 10% or more, the number of layers is determined to be “3”.
受容層厚決定部126は、各矩形ブロックにおいて、印刷属性に基づいて決定した層の数と、印刷率に基づいて決定した層の数とが異なる場合は、数が大きい方の値を採用する。例えば、図4に示す「Block1」において、印刷属性に基づいて決定された層の数が「3」であり、印刷率に基づいて決定された層の数が「2」である場合、受容層厚決定部126は、「3」を採用し、「Block1」における層の数は「3」である旨の情報を受容層形成部200に出力(送信)する。
In each rectangular block, when the number of layers determined based on the printing attribute and the number of layers determined based on the printing rate are different in each rectangular block, the receptive layer thickness determination unit 126 adopts the value with the larger number. . For example, in “Block 1” shown in FIG. 4, when the number of layers determined based on the printing attribute is “3” and the number of layers determined based on the printing rate is “2”, the receiving layer is The thickness determination unit 126 adopts “3” and outputs (transmits) information to the effect that the number of layers in “Block 1” is “3” to the receiving layer forming unit 200.
なお、受容層厚決定部126は、矩形ブロックごとにインク受容層104の厚さを決定することができれば、インク受容層104を形成する層の数ではなく、インク受容層104の厚さと相関するその他の事項を決定することにより、インク受容層104の厚さを決定してもよい。例えば、受容層厚決定部126は、受容層形成部200の電位を決定することによりインク受容層104の厚さを決定してもよい。
If the thickness of the ink receiving layer 104 can be determined for each rectangular block, the receiving layer thickness determining unit 126 correlates with the thickness of the ink receiving layer 104, not the number of layers forming the ink receiving layer 104. The thickness of the ink receiving layer 104 may be determined by determining other matters. For example, the receiving layer thickness determining unit 126 may determine the thickness of the ink receiving layer 104 by determining the potential of the receiving layer forming unit 200.
1.1.3. 受容層形成部
受容層形成部200には、処理部120から、生成された矩形ブロックごとの座標に関する情報(矩形ブロック座標情報)および矩形ブロックごとに対するインク受容層104の厚さに関する情報(インク受容層厚さ情報)が入力される。図5は、受容層形成部200を模式的に示す図である。 1.1.3. Receptive Layer Forming Unit In the receivinglayer forming unit 200, the processing unit 120 generates information on coordinates of each rectangular block (rectangular block coordinate information) and information on the thickness of the ink receiving layer 104 for each rectangular block (ink acceptance Layer thickness information is input. FIG. 5 is a view schematically showing the receiving layer forming unit 200. As shown in FIG.
受容層形成部200には、処理部120から、生成された矩形ブロックごとの座標に関する情報(矩形ブロック座標情報)および矩形ブロックごとに対するインク受容層104の厚さに関する情報(インク受容層厚さ情報)が入力される。図5は、受容層形成部200を模式的に示す図である。 1.1.3. Receptive Layer Forming Unit In the receiving
受容層形成部200は、図5に示すように、基材供給部210と、搬送部220と、感光体230と、帯電部240と、露光部250と、現像部260と、転写部270と、定着部280と、を有している。搬送部220、感光体230、帯電部240、露光部250、現像部260、転写部270、および定着部280は、例えば、筐体290に収容されている。受容層形成部200は、インク受容層104を形成するための材料(複合体)を、基材102に付着させてインク受容層104を形成する。
As shown in FIG. 5, the receptive layer forming unit 200 includes a base material supply unit 210, a transport unit 220, a photosensitive member 230, a charging unit 240, an exposure unit 250, a developing unit 260, and a transfer unit 270. , And a fixing unit 280. The conveyance unit 220, the photosensitive member 230, the charging unit 240, the exposure unit 250, the developing unit 260, the transfer unit 270, and the fixing unit 280 are housed in a housing 290, for example. The receptive layer forming portion 200 adheres a material (composite) for forming the ink receptive layer 104 to the substrate 102 to form the ink receptive layer 104.
基材供給部210は、搬送部220に基材102を供給する。基材供給部210は、搬送部220に基材102を連続的に投入するための自動投入部である。基材供給部210は、基材102を1枚ごとに(毎葉に)供給してもよい。
The base material supply unit 210 supplies the base material 102 to the transport unit 220. The substrate supply unit 210 is an automatic loading unit for continuously loading the substrate 102 into the transport unit 220. The substrate supply unit 210 may supply the substrates 102 one by one (for each leaf).
搬送部220は、基材102を感光体230に向けて搬送する。搬送部220は、搬送ベルト222と、搬送ローラー224と、を有している。搬送ベルト222は、搬送ローラー224の回転に伴い、移動可動である。基材102は、搬送ベルト222上に載置されて搬送される。なお、搬送部220は、搬送ベルト222ではなく、搬送ローラー対によって基材102を挟持し搬送してもよい。
The transport unit 220 transports the substrate 102 toward the photosensitive member 230. The transport unit 220 has a transport belt 222 and a transport roller 224. The transport belt 222 is movable as the transport roller 224 rotates. The substrate 102 is placed on the transport belt 222 and transported. In addition, the conveyance part 220 may pinch and convey the base material 102 not by the conveyance belt 222 but by the conveyance roller pair.
感光体230は、基材102に、インク受容層104を形成するための複合体を転写させる。感光体230は、円筒状(ドラム状)の形状を有している。感光体230の表面(外周面)は、例えば、有機感光体によって形成されている。感光体230は、回転駆動する。感光体230の周囲には、感光体230の回転方向に沿って、帯電部240、露光部250、現像部260、および転写部270が順に配列されている。
The photoreceptor 230 transfers the composite for forming the ink receiving layer 104 to the substrate 102. The photosensitive member 230 has a cylindrical (drum-like) shape. The surface (outer peripheral surface) of the photosensitive member 230 is formed of, for example, an organic photosensitive member. The photosensitive member 230 is rotationally driven. Around the photosensitive member 230, the charging unit 240, the exposure unit 250, the developing unit 260, and the transfer unit 270 are arranged in order along the rotational direction of the photosensitive member 230.
帯電部240は、感光体230の表面を一様に帯電させる。帯電部240は、例えば、感光体230の表面を、負電位に帯電させる。帯電部240は、例えば、オゾンを照射するコロナ帯電器や帯電ブラシ、帯電フィルムであり、図示の例では、ローラーの形状を有している。
The charging unit 240 uniformly charges the surface of the photosensitive member 230. The charging unit 240 charges, for example, the surface of the photosensitive member 230 to a negative potential. The charging unit 240 is, for example, a corona charger, a charging brush, or a charging film that irradiates ozone, and in the illustrated example, has a shape of a roller.
露光部250は、感光体230の表面を露光し、感光体230の表面の電位を調整する。露光部250は、感光体230の表面に例えばレーザー光を照射し、複合体が感光体230の表面に移動付着されるような電位に調整する。露光部250は、例えば、感光体230の表面の一部を徐電することにより、感光体230の表面の電位を調整する。
The exposure unit 250 exposes the surface of the photosensitive member 230 and adjusts the potential of the surface of the photosensitive member 230. The exposure unit 250 irradiates the surface of the photosensitive member 230 with, for example, a laser beam, and adjusts the potential to move and deposit the composite on the surface of the photosensitive member 230. The exposure unit 250 adjusts the potential of the surface of the photosensitive member 230, for example, by discharging a part of the surface of the photosensitive member 230.
現像部260は、インク受容層104を形成するための複合体を、感光体230の表面に移動付着させる。現像部260は、カートリッジ261を有している。カートリッジ261には、攪拌機262、供給ローラー263、現像ローラー264、およびブレード265が収容されている。複合体は、カートリッジ261内の貯蔵部に収容されている。カートリッジ261は、受容層形成部200に着脱可能に装着されている。攪拌機262は、回転することにより複合体を攪拌し帯電させて、供給ローラー263に供給する。現像ローラー264は、供給ローラー263と電位差を有し、複合体を静電付着させる。ブレード265は、複合体を薄膜化し、摩擦帯電させる。現像ローラー264の表面に付着された複合体は、感光体230と現像ローラー264との間の電位差により、感光体230の表面に移動付着する。感光体230と現像ローラー264との電位は、適宜設定される。
The developing unit 260 moves and deposits the complex for forming the ink receiving layer 104 on the surface of the photosensitive member 230. The developing unit 260 has a cartridge 261. In the cartridge 261, a stirrer 262, a supply roller 263, a developing roller 264, and a blade 265 are accommodated. The composite is housed in a storage section in the cartridge 261. The cartridge 261 is detachably mounted to the receiving layer forming unit 200. The agitator 262 agitates and charges the complex by rotating and supplies it to the supply roller 263. The development roller 264 has a potential difference with the supply roller 263 to electrostatically attach the composite. The blade 265 thins the composite and frictionally charges it. The composite attached to the surface of the developing roller 264 is moved and attached to the surface of the photosensitive member 230 due to the potential difference between the photosensitive member 230 and the developing roller 264. The potentials of the photosensitive member 230 and the developing roller 264 are appropriately set.
転写部270は、感光体230の表面に付着された複合体を、基材102に転写する。図示の例では、転写部270は、ローラーの形状を有し、搬送ベルト222を移動させるローラーとしての機能も有している。転写部270は、搬送ベルト222を挟んで感光体230と対向し、感光体230とともに基材102を挟持可能な位置に設けられている。転写部270は、所定の電位を有している。感光体230の表面に付着された複合体は、感光体230と転写部270との間の電位差により、基材102に転写される。すなわち、複合体は、基材102に静電塗布される。搬送部220は、複合体が設けられた基材102を、定着部280に向けて搬送する。
The transfer unit 270 transfers the composite attached to the surface of the photosensitive member 230 to the substrate 102. In the illustrated example, the transfer unit 270 has a roller shape, and also has a function as a roller for moving the transport belt 222. The transfer unit 270 opposes the photosensitive member 230 with the conveyance belt 222 interposed therebetween, and is provided at a position where the base unit 102 can be held together with the photosensitive member 230. The transfer unit 270 has a predetermined potential. The composite attached to the surface of the photosensitive member 230 is transferred to the substrate 102 by the potential difference between the photosensitive member 230 and the transfer unit 270. That is, the composite is electrostatically applied to the substrate 102. The transport unit 220 transports the base material 102 provided with the composite toward the fixing unit 280.
定着部280は、基材102に転写された複合体を、基材102に定着させる。図示の例では、定着部280は、ローラーの形状を有している。定着部280は、例えば、基材102および複合体を挟持して加熱および加圧することにより、複合体を基材102に定着させる。定着部280が加圧する圧力は、例えば、100kg以上1000kg以下である。定着部280が加熱する温度は、例えば、100℃以上250℃以下である。
The fixing unit 280 fixes the composite transferred to the base 102 to the base 102. In the illustrated example, the fixing unit 280 has a roller shape. The fixing unit 280 fixes the composite on the substrate 102, for example, by sandwiching the substrate 102 and the composite, and applying heat and pressure. The pressure applied by the fixing unit 280 is, for example, 100 kg or more and 1000 kg or less. The temperature to which the fixing unit 280 heats is, for example, 100 ° C. or more and 250 ° C. or less.
処理部120は、例えば、矩形ブロック座標情報およびインク受容層厚さ情報に基づいて、感光体230および露光部250を制御し、各矩形ブロックに対応する感光体230の表面への、複合体の付着回数を制御する。これにより、各矩形ブロックに対応する部分に形成されるインク受容層104の厚さは、調整される。例えば、図4に示すような矩形ブロックの場合では、処理部120は、感光体230を3回転させる間に、「Block1」に対応する部分には複合体を3層(3回)付着させ、「Block2」に対応する部分には複合体を1層付着させ、「Block3」に対応する部分には複合体を3層付着させるように、露光部250を制御する。これにより、受容層形成部200は、受容層厚決定部126において決定された厚さを有する部分104a,104b,104cを、基材102上に形成することができる。
The processing unit 120 controls the photosensitive member 230 and the exposure unit 250 based on, for example, rectangular block coordinate information and ink receptive layer thickness information, and sets the composite on the surface of the photosensitive member 230 corresponding to each rectangular block. Control the number of adhesions. Thereby, the thickness of the ink receiving layer 104 formed in the portion corresponding to each rectangular block is adjusted. For example, in the case of a rectangular block as shown in FIG. 4, the processing unit 120 causes three layers (three times) of the composite to be attached to the portion corresponding to “Block 1” while rotating the photosensitive member 230 three times. The exposure unit 250 is controlled so that one composite layer is attached to the portion corresponding to “Block 2” and three composite layers are attached to the portion corresponding to “Block 3”. Thus, the receiving layer forming unit 200 can form the portions 104 a, 104 b and 104 c having the thickness determined by the receiving layer thickness determining unit 126 on the substrate 102.
さらに、受容層形成部200は、部分104a,104b,104cとともに、図2に示すシンボル用インク受容層105を形成する。シンボル用インク受容層105の厚さは、特に限定されないが、シンボルSIに応じた厚さにすることが好ましい。例えば、シンボルSIが文字の場合には、複合体を1層付着させる。
Furthermore, the receiving layer forming unit 200 forms the symbol ink receiving layer 105 shown in FIG. 2 together with the portions 104a, 104b, and 104c. The thickness of the symbol ink receptive layer 105 is not particularly limited, but is preferably a thickness corresponding to the symbol SI. For example, in the case where the symbol SI is a letter, one layer of the complex is attached.
以上により、受容層形成部200は、基材102と、インク受容層104と、を有する記録媒体106を形成する。記録媒体106は、例えば、図示せぬローラーによって、受容層形成部200の外部に排出され、例えば自動的にインクジェット印刷部300に搬送される。なお、記録媒体106を外部に排出するためのローラーは、定着部280が兼ねてもよい。
As described above, the receiving layer forming unit 200 forms the recording medium 106 having the base material 102 and the ink receiving layer 104. The recording medium 106 is discharged to the outside of the receiving layer forming unit 200 by, for example, a roller (not shown), and is automatically conveyed to the inkjet printing unit 300, for example. The fixing unit 280 may double as a roller for discharging the recording medium 106 to the outside.
なお、処理部120は、矩形ブロック座標情報およびインク受容層厚さ情報に基づいて、露光部250を制御し、各矩形ブロックに対応する感光体230の表面の電位を調整してもよい。これにより、各矩形ブロックに対応する部分のインク受容層104の厚さを調整してもよい。
The processing unit 120 may control the exposure unit 250 based on the rectangular block coordinate information and the ink receptive layer thickness information to adjust the potential of the surface of the photosensitive member 230 corresponding to each rectangular block. Thereby, the thickness of the ink receiving layer 104 in the portion corresponding to each rectangular block may be adjusted.
また、上記では、インク受容層104が複数の部分に分かれて島状に形成される例について説明したが、印刷情報によっては、インク受容層104は、基材102の全面もしくは余白を残した略全面に形成される場合もある。
Further, although the example in which the ink receiving layer 104 is divided into a plurality of portions and formed in an island shape has been described above, depending on the printing information, the ink receiving layer 104 is substantially the entire substrate 102 or the remaining margin. It may be formed on the entire surface.
1.1.4. インクジェット印刷部
インクジェット印刷部300は、図1に示すように、印刷情報受信部110が受信した印刷情報に基づいて、形成部100によって形成された記録媒体106のインク受容層104に印刷を行う。インクジェット印刷部300から吐出されたインクは、インク受容層104に浸透し、例えば図2に示すような記録物108が形成される。インクジェット印刷部300は、例えば、インクジェットプリンターによって実現される。なお、印刷情報は、処理部120を介してインクジェット印刷部300に入力されてもよいし、処理部120を介さずに印刷情報受信部110から直接インクジェット印刷部300に入力されてもよい。 1.1.4. Inkjet Printing Unit As shown in FIG. 1, theinkjet printing unit 300 performs printing on the ink receiving layer 104 of the recording medium 106 formed by the forming unit 100 based on the print information received by the print information receiving unit 110. The ink ejected from the ink jet printing unit 300 penetrates the ink receiving layer 104, and a recorded matter 108 as shown in FIG. 2, for example, is formed. The inkjet printing unit 300 is realized by, for example, an inkjet printer. The print information may be input to the inkjet printing unit 300 via the processing unit 120, or may be directly input to the inkjet printing unit 300 from the print information receiving unit 110 without via the processing unit 120.
インクジェット印刷部300は、図1に示すように、印刷情報受信部110が受信した印刷情報に基づいて、形成部100によって形成された記録媒体106のインク受容層104に印刷を行う。インクジェット印刷部300から吐出されたインクは、インク受容層104に浸透し、例えば図2に示すような記録物108が形成される。インクジェット印刷部300は、例えば、インクジェットプリンターによって実現される。なお、印刷情報は、処理部120を介してインクジェット印刷部300に入力されてもよいし、処理部120を介さずに印刷情報受信部110から直接インクジェット印刷部300に入力されてもよい。 1.1.4. Inkjet Printing Unit As shown in FIG. 1, the
インクジェット印刷部300は、図2に示すように、シンボル用インク受容層105にシンボルSIを印刷する。シンボルSIは、形成部100で形成されたインク受容層104の位置に関する情報を含む。具体的には、シンボルSIは、インク受容層104の部分104a,104b,104cに対応する矩形ブロックの座標に関する情報を含む。さらに、シンボルSIは、部分104a,104b,104cに対応する矩形ブロックの印刷率に関する情報を含んでいてもよい。さらに、シンボルSIは、記録媒体106を製造する企業や団体名などの組織名、所有者、記録媒体106に印刷された日時、記録物108が保存される期間等に関する情報を含んでいてもよい。
The inkjet printing unit 300 prints the symbol SI on the symbol ink receiving layer 105, as shown in FIG. The symbol SI includes information on the position of the ink receiving layer 104 formed in the forming unit 100. Specifically, the symbol SI includes information on the coordinates of the rectangular block corresponding to the portions 104 a, 104 b and 104 c of the ink receiving layer 104. Further, the symbol SI may include information on the printing ratio of rectangular blocks corresponding to the portions 104a, 104b, and 104c. Furthermore, the symbol SI may include information on an organization name such as a company or group name that manufactures the recording medium 106, an owner, a date printed on the recording medium 106, a period for which the recorded matter 108 is stored, and the like. .
シンボルSIは、例えば、1次元バーコード、2次元コード(QRコード(登録商標))等により実現される。または、シンボルSIは、文字、記号、図形、またはこれらを組み合わせたものにより実現されてもよい。ただし、記録できる情報量、リードソロモン符号による誤り訂正機能があること等を考慮すると、シンボルSIは、2次元コードにより実現されることが望ましい。
The symbol SI is realized by, for example, a one-dimensional barcode, a two-dimensional code (QR code (registered trademark)), or the like. Alternatively, the symbol SI may be realized by a character, a symbol, a figure, or a combination thereof. However, it is desirable that the symbol SI be realized by a two-dimensional code, in consideration of the amount of information that can be recorded, the presence of an error correction function by a Reed-Solomon code, and the like.
なお、シンボルSIは、インクジェット印刷部300ではなく、受容層形成部200によって形成されてもよい。すなわち、シンボルSIは、インクジェット印刷部300によって吐出されるインクではなく、インク受容層104によって(シンボル用インク受容層105によって)構成されていてもよい。より詳しくは、矩形のシンボル用インク受容層105に代えて、シンボルSIの像を表すように複合体を基材102に付着させればよい。これにより、インクジェット印刷部300によって吐出されるインクの消費量を抑えることができる。
The symbol SI may be formed not by the inkjet printing unit 300 but by the receiving layer forming unit 200. That is, the symbol SI may be configured by the ink receiving layer 104 (by the symbol ink receiving layer 105) instead of the ink ejected by the inkjet printing unit 300. More specifically, instead of the rectangular symbol ink receiving layer 105, a composite may be attached to the substrate 102 so as to represent an image of the symbol SI. Thereby, the consumption of the ink discharged by the inkjet printing part 300 can be restrained.

例えば、ユーザーの端末装置から送信された印刷情報を印刷情報受信部110が受信すると、処理部120は処理を開始する。
For example, when the print information receiving unit 110 receives the print information transmitted from the terminal device of the user, the processing unit 120 starts processing.
まず、処理部120の印刷属性判定部122は、印刷情報を受けて、上述のように矩形ブロックを生成する(ステップS2)。
First, the print attribute determination unit 122 of the processing unit 120 receives the print information and generates a rectangular block as described above (step S2).
次に、印刷属性判定部122は、生成された矩形ブロックの形状や大きさ等から、生成された矩形ブロックの印刷属性を判定する(ステップS4)。印刷属性判定部122は、さらに、生成された矩形ブロックの座標を求める(ステップS6)。なお、ステップS4とステップS6の順序は、特に限定されない。
Next, the print attribute determination unit 122 determines the print attribute of the generated rectangular block from the shape, size, and the like of the generated rectangular block (step S4). The print attribute determination unit 122 further obtains the coordinates of the generated rectangular block (step S6). The order of steps S4 and S6 is not particularly limited.
次に、処理部120の印刷率導出部124は、印刷属性が判定された矩形ブロックごとに、印刷率を算出する(ステップS8)。
Next, the printing ratio deriving unit 124 of the processing unit 120 calculates the printing ratio for each rectangular block for which the printing attribute has been determined (step S8).
次に、処理部120の受容層厚決定部126は、印刷属性判定部122において判定された印刷属性、および印刷率導出部124において算出された印刷率に基づいて、矩形ブロックごとにインク受容層104の厚さを決定する(ステップS10)。
Next, the receptive layer thickness determination unit 126 of the processing unit 120 determines the ink receptive layer for each rectangular block based on the printing attribute determined by the printing attribute determination unit 122 and the printing rate calculated by the printing rate deriving unit 124. The thickness of 104 is determined (step S10).
次に、インク受容層104を形成する(ステップS12)。具体的には、処理部120は、例えば、印刷属性判定部122において求められた矩形ブロック座標情報、および受容層厚決定部126において決定されたインク受容層厚さ情報に基づいて、受容層形成部200を制御する。より具体的には、処理部120は、矩形ブロック座標情報および受容層厚さ情報に基づいて、感光体230および露光部250を制御し、各矩形ブロックに対応する感光体230の表面への、複合体の付着回数を制御する。これにより、各矩形ブロックに対応する部分に形成されるインク受容層104の厚さは調整され、受容層形成部200は、受容層厚決定部126において決定された厚さを有する部分104a,104b,104cを、基材102上に形成することができる。このように、印刷情報に基づいて、基材102上にインク受容層104を形成し、記録媒体106を製造することができる。
Next, the ink receiving layer 104 is formed (step S12). Specifically, the processing unit 120 forms the receiving layer based on, for example, the rectangular block coordinate information obtained in the print attribute determining unit 122 and the ink receiving layer thickness information determined in the receiving layer thickness determining unit 126. Control unit 200; More specifically, the processing unit 120 controls the photosensitive member 230 and the exposure unit 250 based on the rectangular block coordinate information and the receptive layer thickness information, and controls the surface of the photosensitive member 230 corresponding to each rectangular block, Control the number of adhesions of the complex. Thereby, the thickness of the ink receiving layer 104 formed in the portion corresponding to each rectangular block is adjusted, and the receiving layer forming portion 200 has the portions 104a and 104b having the thickness determined in the receiving layer thickness determining portion 126. , 104c can be formed on the substrate 102. Thus, based on the printing information, the ink receiving layer 104 can be formed on the substrate 102, and the recording medium 106 can be manufactured.
次に、インク受容層104に印刷する(ステップS14)。具体的には、処理部120は、印刷情報に基づいてインクジェット印刷部300を制御する。これにより、インクジェット印刷部300は、インク受容層104にインクを吐出し、インクジェット印刷部300によって印刷された記録物108を得ることができる。そして、処理部120は、処理を終了する。
Next, printing is performed on the ink receiving layer 104 (step S14). Specifically, the processing unit 120 controls the inkjet printing unit 300 based on the printing information. Thus, the inkjet printing unit 300 can eject the ink to the ink receiving layer 104 and obtain the recorded matter 108 printed by the inkjet printing unit 300. Then, the processing unit 120 ends the processing.

As a result, the printing apparatus 1000 can prevent the material of the ink receiving layer 104 (the composite for forming the ink receiving layer 104) from being wasted. Therefore, in the printing apparatus 1000, cost reduction can be achieved. Furthermore, in the printing apparatus 1000, compared with the case where the ink receiving layer 104 is always formed on the entire surface of the substrate 102, for example, the processing time for forming the ink receiving layer 104 can be shortened. Furthermore, in the printing apparatus 1000, the substrate 102 can be reused by peeling off the ink receiving layer 104 printed by the inkjet printing unit 300.
印刷装置1000では、形成部100は、インク受容層104の厚さを、印刷情報に基づいて決定する。そのため、印刷装置1000では、印刷情報に基づいて、インク受容層104の部分104a,104b,104cの厚さを調整することができる。これにより、印刷装置1000では、基材102にまでインクが浸透することを抑制しつつ、インク受容層104の材料の消費量を抑えることができ、インク受容層104を効率よく形成することができる。
In the printing apparatus 1000, the forming unit 100 determines the thickness of the ink receiving layer 104 based on the print information. Therefore, in the printing apparatus 1000, the thickness of the portions 104a, 104b, and 104c of the ink receiving layer 104 can be adjusted based on the print information. Thus, in the printing apparatus 1000, the consumption of the material of the ink receiving layer 104 can be suppressed while the penetration of the ink to the substrate 102 can be suppressed, and the ink receiving layer 104 can be formed efficiently. .
印刷装置1000では、形成部100は、印刷情報から印刷率を導出する印刷率導出部124を有し、印刷率に基づいて、インク受容層104の厚さを決定する。そのため、印刷装置1000は、印刷率に応じた厚さのインク受容層104を形成することができる。
In the printing apparatus 1000, the forming unit 100 includes a print ratio deriving unit 124 that derives a print ratio from print information, and determines the thickness of the ink receiving layer 104 based on the print ratio. Therefore, the printing apparatus 1000 can form the ink receiving layer 104 having a thickness corresponding to the printing rate.
印刷装置1000では、形成部100は、印刷情報から印刷属性を判定する印刷属性判定部122を有し、印刷属性に基づいて、インク受容層104の厚さを決定する。そのため、印刷装置1000は、印刷属性に応じた厚さのインク受容層104を形成することができる。
In the printing apparatus 1000, the forming unit 100 includes a print attribute determination unit 122 that determines a print attribute from print information, and determines the thickness of the ink receiving layer 104 based on the print attribute. Therefore, the printing apparatus 1000 can form the ink receiving layer 104 having a thickness corresponding to the printing attribute.
印刷装置1000では、形成部100は、インク受容層104の位置に関する情報を含むシンボルSIを印刷するためのシンボル用インク受容層105を形成し、インクジェット印刷部300は、シンボル用インク受容層105にシンボルSIを印刷する。そのため、例えば、インクジェット印刷部300によって印刷されたインク受容層104を剥離する際に、シンボルSIを読み取って、形成されたインク受容層104の位置に関する情報を取得することができる。そして、取得したインク受容層104の位置に関する情報に基づいて、インク受容層104を剥離するための剥離処理を、記録物108の選択的な部分(インク受容層104が形成されている部分)に対して行うことができる。したがって、印刷装置1000では、剥離処理を選択的な部分に対して行うことができる記録物108を形成することができ、常に記録物108の全面に対して剥離処理を行う場合に比べて、剥離処理の時間短縮化および低コスト化を図ることができる。
In the printing apparatus 1000, the forming unit 100 forms a symbol ink receiving layer 105 for printing a symbol SI including information on the position of the ink receiving layer 104, and the inkjet printing unit 300 forms the symbol ink receiving layer 105. Print the symbol SI. Therefore, for example, when peeling off the ink receiving layer 104 printed by the inkjet printing unit 300, the symbol SI can be read to obtain information on the position of the formed ink receiving layer 104. Then, based on the acquired information on the position of the ink receiving layer 104, the peeling process for peeling the ink receiving layer 104 is performed on a selective portion (the portion on which the ink receiving layer 104 is formed) of the recorded matter 108. It can be done against. Therefore, the printing apparatus 1000 can form the recorded matter 108 capable of performing the peeling process on selective portions, and peeling is always performed as compared with the case where the peeling process is always performed on the entire surface of the recorded matter 108. The processing time can be shortened and the cost can be reduced.

FIG. 7 is a functional block diagram of theprinting apparatus 2000 according to the second embodiment. Hereinafter, in the printing apparatus 2000 according to the second embodiment, members having the same functions as the constituent members of the printing apparatus 1000 according to the first embodiment described above are given the same reference numerals, and the detailed description thereof is omitted. .
2.1. 印刷装置
次に、第2実施形態に係る印刷装置について、図面を参照しながら説明する。図7は、第2実施形態に係る印刷装置2000の機能ブロック図である。以下、第2実施形態に係る印刷装置2000において、上述した第1実施形態に係る印刷装置1000の構成部材と同様の機能を有する部材については同一の符号を付し、その詳細な説明を省略する。 2. Second Embodiment 2.1. Printing Device Next, a printing device according to the second embodiment will be described with reference to the drawings. FIG. 7 is a functional block diagram of the
印刷装置2000では、図7に示すように、基材状態判定部128と、読取部400と、シート製造装置500と、を有している点において、上述した印刷装置1000と異なる。
The printing apparatus 2000 is different from the above-described printing apparatus 1000 in that the printing apparatus 2000 includes a base material state determination unit 128, a reading unit 400, and a sheet manufacturing apparatus 500, as shown in FIG.
2.1.1. 基材状態判定部
処理部120は、基材状態判定部128を有している。基材状態判定部128は、基材102の状態に応じて、基材102上にインク受容層104を形成するか否かを判定する。具体的には、基材状態判定部128は、印刷情報受信部110からの印刷情報が入力されると、読取部400を制御して、基材102の表面をスキャンし、スキャン情報を取得する。そして、基材状態判定部128は、取得したスキャン情報に基づいて、基材102の状態を判定し、インク受容層104を形成するか否かを判定する。基材状態判定部128が「インク受容層104を形成する」と判定した場合、基材102は、例えば、自動的に受容層形成部200に搬送される。一方、基材状態判定部128が「インク受容層104を形成しない」と判定した場合、基材102は、例えば、自動的にシート製造装置500に搬送される。 2.1.1. Substrate state determination unit Theprocessing unit 120 includes a substrate state determination unit 128. The substrate state determination unit 128 determines whether to form the ink receiving layer 104 on the substrate 102 in accordance with the state of the substrate 102. Specifically, when the print information from the print information receiving unit 110 is input, the substrate state determination unit 128 controls the reading unit 400 to scan the surface of the substrate 102 and acquire scan information. . Then, the base material state determination unit 128 determines the state of the base material 102 based on the acquired scan information, and determines whether to form the ink receiving layer 104 or not. If the substrate state determination unit 128 determines that “the ink receiving layer 104 is to be formed,” the substrate 102 is, for example, automatically transported to the receiving layer forming unit 200. On the other hand, when the substrate state determination unit 128 determines that “the ink receiving layer 104 is not formed”, the substrate 102 is, for example, automatically conveyed to the sheet manufacturing apparatus 500.
処理部120は、基材状態判定部128を有している。基材状態判定部128は、基材102の状態に応じて、基材102上にインク受容層104を形成するか否かを判定する。具体的には、基材状態判定部128は、印刷情報受信部110からの印刷情報が入力されると、読取部400を制御して、基材102の表面をスキャンし、スキャン情報を取得する。そして、基材状態判定部128は、取得したスキャン情報に基づいて、基材102の状態を判定し、インク受容層104を形成するか否かを判定する。基材状態判定部128が「インク受容層104を形成する」と判定した場合、基材102は、例えば、自動的に受容層形成部200に搬送される。一方、基材状態判定部128が「インク受容層104を形成しない」と判定した場合、基材102は、例えば、自動的にシート製造装置500に搬送される。 2.1.1. Substrate state determination unit The
ここで、「基材102の状態」とは、「折り曲げ」や「しわ」等による基材102の汚損具合のことである。基材状態判定部128は、スキャン情報の各画素の濃度を利用して、横方向空間フィルタ処理と縦方向空間フィルタ処理とよって「折り曲げ」、「しわ」で変化する濃度を強調し、2値化処理で「折り曲げ」、「しわ」の画素を抽出する。そして、基材状態判定部128は、抽出した画素数または画素の濃度値の平均値などを算出することにより、汚損具合を推定し、推定した汚損具合と、例えば記憶部130に記憶されている基準値と、を特徴量解析により比較する。基材状態判定部128は、推定した汚損具合が基準値未満である場合、「インク受容層104を形成する」と判定する。一方、基材状態判定部128は、推定した汚損具合が基準値以上である場合、「インク受容層104を形成しない」と判定する。
Here, the "state of the base material 102" refers to the degree of contamination of the base material 102 due to "folding", "wrinkling" or the like. The substrate state determination unit 128 uses the density of each pixel of the scan information to emphasize the density that changes due to “folding” and “wrinkling” by the horizontal space filtering process and the vertical space filtering process, and provides a binary value. Extract the "folded" and "wrinkled" pixels in the image processing. Then, the base material state determination unit 128 estimates the contamination condition by calculating the extracted number of pixels, the average value of the density values of the pixels, and the like, and stores the estimated contamination condition, for example, in the storage unit 130. The reference value is compared by feature amount analysis. The substrate state determination unit 128 determines that “the ink receiving layer 104 is to be formed” when the estimated contamination degree is less than the reference value. On the other hand, the base material state determination unit 128 determines that “the ink receiving layer 104 is not formed” when the estimated contamination degree is equal to or more than the reference value.
なお、「折り曲げ」、「しわ」は、汚損具合の一例であり、他にも面積、太さ、方向、明度など画像情報から特定できる指標を、基材状態判定部128が計測する汚損具合として利用してもよい。
Note that “bending” and “wrinkle” are an example of the staining condition, and other indicators that can be specified from image information such as area, thickness, direction, and brightness are the staining condition measured by the substrate state determination unit 128 You may use it.
また、基材状態判定部128における汚れ具合の解析方法は、上記のような画素濃度解析による方法に限定されず、例えば、平均輝度計測法、画素数計測法等を用いてもよい。
Further, the method of analyzing the degree of contamination in the base material state determination unit 128 is not limited to the method by the pixel density analysis as described above. For example, an average luminance measurement method, a pixel count measurement method, or the like may be used.
2.1.2. 読取部
読取部400は、基材102の表面をスキャンする。読取部400は、例えば、CCD(Charge Coupled Devices)型のスキャナー、CIS(Contact Image Sensor)型のスキャナーによって実現される。なお、読取部400は、基材102の表面をスキャンすることができれば、スキャナーの型は上記に限定されない。 2.1.2. Reading Unit Thereading unit 400 scans the surface of the substrate 102. The reading unit 400 is realized by, for example, a CCD (Charge Coupled Devices) scanner and a CIS (Contact Image Sensor) scanner. The type of the scanner is not limited to the above as long as the reading unit 400 can scan the surface of the base material 102.
読取部400は、基材102の表面をスキャンする。読取部400は、例えば、CCD(Charge Coupled Devices)型のスキャナー、CIS(Contact Image Sensor)型のスキャナーによって実現される。なお、読取部400は、基材102の表面をスキャンすることができれば、スキャナーの型は上記に限定されない。 2.1.2. Reading Unit The

Sheet manufacturing apparatus Thesheet manufacturing apparatus 500 manufactures a sheet by disentangling the base material 102 determined as the base material state determination unit 128 "does not form the ink receiving layer 104". The detailed description of the sheet manufacturing apparatus 500 will be described later. The base material 102 determined to “do not form the ink receiving layer 104” may be discarded without being transported to the sheet manufacturing apparatus 500. FIG. 8 schematically shows the sheet manufacturing apparatus 500. As shown in FIG.
シート製造装置500は、基材状態判定部128が「インク受容層104を形成しない」と判定した基材102を解繊して、シートを製造する。シート製造装置500の詳細な説明は、後述する。なお、「インク受容層104を形成しない」と判定された基材102は、シート製造装置500に搬送されずに、廃却されてもよい。図8は、シート製造装置500を模式的に示す図である。 2.1.3. Sheet manufacturing apparatus The

The supply unit 10 supplies the raw material (the base material 102 determined as “do not form the ink receiving layer 104” in the base material state determination unit 128) to the crushing part 12. The feeding unit 10 is, for example, an automatic feeding unit for continuously feeding the raw material into the crushing unit 12.
粗砕部12は、供給部10によって供給された原料を、大気中(空気中)等の気中で裁断して(粗砕して)粗砕片にする。粗砕片の形状や大きさは、例えば、数cm角の細片である。粗砕部12は、例えば、粗砕刃14と、シューター(ホッパー)16と、を有している。粗砕部12は、粗砕刃14によって、投入された原料を裁断することができる。粗砕部12としては、例えば、シュレッダーを用いる。粗砕刃14によって裁断された原料は、シューター16で受けてから管2を介して、解繊部20に移送(搬送)される。
The crushing unit 12 cuts (crushes) the raw material supplied by the supply unit 10 in air (in the air) or the like in the atmosphere (in the air) or the like to form crushed pieces. The shape and size of the coarse fragments are, for example, several cm square pieces. The crushing unit 12 includes, for example, a crushing blade 14 and a shooter (hopper) 16. The crushing unit 12 can cut the input raw material by the crushing blade 14. As the crushing part 12, a shredder is used, for example. The raw material cut by the crushing blade 14 is received by the shooter 16 and then transferred (conveyed) to the defibrating unit 20 through the pipe 2.
解繊部20は、粗砕部12によって裁断された原料(粗砕片)を解繊物に解繊する。ここで、「解繊する」とは、複数の繊維が結着されてなる原料(被解繊物)を、繊維1本1本に解きほぐすことをいう。解繊部20は、原料に付着した樹脂粒やインク、トナー、にじみ防止剤等の物質を、繊維から分離させる機能をも有する。
The defibration unit 20 disintegrates the raw material (crushed pieces) cut by the crusher 12 into disintegrated materials. Here, "disintegrate" refers to disentangling a raw material (broken material) in which a plurality of fibers are bound into one fiber. The defibrating unit 20 also has a function of separating substances such as resin particles, ink, toner, and anti-smearing agents attached to the raw material from fibers.
解繊部20を通過したものを「解繊物」という。「解繊物」には、解きほぐされた解繊物繊維の他に、繊維を解きほぐす際に繊維から分離した樹脂(複数の繊維同士を結着させるための樹脂)粒や、インク、トナーなどの色剤や、にじみ防止材、紙力増強剤等の添加剤を含んでいる場合もある。解きほぐされた解繊物の形状は、ひも(string)状や平ひも(ribbon)状である。解きほぐされた解繊物は、他の解きほぐされた繊維と絡み合っていない状態(独立した状態)で存在してもよいし、他の解きほぐされた解繊物と絡み合って塊状となった状態(いわゆる「ダマ」を形成している状態)で存在してもよい。
What passed through the defibrating unit 20 is referred to as "defibrated material". “Diswoven materials” include, in addition to disentangled fibrillated fibers, resin particles (resin for binding a plurality of fibers) particles separated from the fibers when disentangling fibers, ink, toner, etc. And additives such as anti-smearing agents and paper strength agents. The shape of the defibrated material is in the form of a string or a ribbon. The disentangled disaggregated material may exist in a non-entangled state (independent state) with other disentangled fibers, or as entangled with other disentangled disintegrated objects It may exist in a state (in a state of forming a so-called "dummy").
解繊部20は、乾式で解繊を行う。ここで、液体中ではなく、大気中(空気中)等の気中において、解繊等の処理を行うことを乾式と称する。解繊部20として、本実施形態ではインペラーミルを用いる。解繊部20は、原料を吸引し、解繊物を排出するような気流を発生させる機能を有している。これにより、解繊部20は、自ら発生する気流によって、導入口22から原料を気流と共に吸引し、解繊処理して、解繊物を排出口24へと搬送することができる。解繊部20を通過した解繊物は、管3を介して、選別部40に移送される。なお、解繊部20から選別部40に解繊物を搬送させるための気流は、解繊部20が発生させる気流を利用してもよいし、図8に示すように気流発生装置であるブロアー26を設け、その気流を利用してもよい。
The defibrating unit 20 fibrillates in a dry manner. Here, performing processing such as disentanglement in air, such as in the air (in air), not in liquid, is referred to as dry. In the present embodiment, an impeller mill is used as the defibrating unit 20. The defibrating unit 20 has a function of generating a gas flow that sucks in the raw material and discharges the defibrated material. Thereby, the defibrating unit 20 can suck the raw material from the introduction port 22 together with the air flow by the air flow generated by itself, carry out the disintegration processing, and transport the defibrated material to the discharge port 24. The defibrated material that has passed through the defibrating unit 20 is transferred to the sorting unit 40 via the pipe 3. Note that the air flow for conveying the defibrated material from the defibrating unit 20 to the sorting unit 40 may use the air flow generated by the defibrating unit 20, and as shown in FIG. 26 may be provided and the air flow may be used.
選別部40は、解繊部20により解繊された解繊物を導入口42から導入し、繊維の長さによって選別する。選別部40は、ドラム部(篩部)41と、ドラム部41を収容するハウジング部(覆い部)43と、を有している。ドラム部41としては、例えば、篩(ふるい)を用いる。ドラム部41は、網(フィルター、スクリーン)を有し、網の目開き(開口)の大きさより小さい繊維または粒子(網を通過するもの、第1選別物)と、網の目開きの大きさより大きい繊維や未解繊片やダマ(網を通過しないもの、第2選別物)と、を分けることができる。すなわち、選別部40は、解繊物を第1選別物と第2選別物とに選別することができる。例えば、第1選別物は、管7を介して、混合部50に移送される。第2選別物は、排出口44から管8を介して、解繊部20に戻される。具体的には、ドラム部41は、モーターによって回転駆動される円筒の篩である。ドラム部41の網としては、例えば、金網、切れ目が入った金属板を引き延ばしたエキスパンドメタル、金属板にプレス機等で穴を形成したパンチングメタルを用いる。
The sorting unit 40 introduces the defibrated material defibrated by the defibrating unit 20 from the introduction port 42, and sorts according to the length of the fiber. The sorting unit 40 includes a drum unit (sieve unit) 41 and a housing unit (cover unit) 43 that accommodates the drum unit 41. For example, a sieve is used as the drum unit 41. The drum unit 41 has a net (filter, screen), and fibers or particles (those that pass through the net, the first sort) smaller than the size of the net opening (opening), and the size of the net opening It can be divided into large fibers, unbroken pieces and lumps (those not passing through the net, second sorted matter). That is, the sorting unit 40 can sort the defibrated matter into the first sorted matter and the second sorted matter. For example, the first sorted matter is transferred to the mixing unit 50 via the pipe 7. The second sorted matter is returned from the discharge port 44 to the defibrating unit 20 via the pipe 8. Specifically, the drum unit 41 is a sieve of a cylinder rotationally driven by a motor. As the mesh of the drum unit 41, for example, a wire mesh, an expanded metal obtained by extending a metal plate with cuts, and a punching metal in which holes are formed in a metal plate by a press machine or the like are used.
第1ウェブ形成部45は、選別部40を通過した第1選別物を、混合部50に搬送する。第1ウェブ形成部45は、メッシュベルト46と、張架ローラー47と、吸引部(サクション機構)48と、を含む。
The first web forming unit 45 conveys the first sorted matter that has passed through the sorting unit 40 to the mixing unit 50. The first web forming unit 45 includes a mesh belt 46, a tension roller 47, and a suction unit (suction mechanism) 48.
吸引部48は、選別部40の開口(網の開口)を通過して空気中に分散された第1選別物をメッシュベルト46上に吸引することができる。第1選別物は、移動するメッシュベルト46上に堆積し、ウェブVを形成する。メッシュベルト46、張架ローラー47および吸引部48の基本的な構成は、後述する第2ウェブ形成部70のメッシュベルト72、張架ローラー74およびサクション機構76と同様である。
The suction unit 48 can suction the first sorted matter dispersed in the air through the opening (the opening of the net) of the sorting unit 40 onto the mesh belt 46. The first sort is deposited on the moving mesh belt 46 to form the web V. The basic configuration of the mesh belt 46, the tension roller 47, and the suction unit 48 is the same as the mesh belt 72, the tension roller 74, and the suction mechanism 76 of the second web forming unit 70 described later.
ウェブVは、選別部40および第1ウェブ形成部45を経ることにより、空気を多く含み柔らかくふくらんだ状態に形成される。メッシュベルト46に堆積されたウェブVは、管7へ投入され、混合部50へと搬送される。
The web V passes through the sorting unit 40 and the first web forming unit 45, and is formed in a soft and flexible state including a large amount of air. The web V deposited on the mesh belt 46 is introduced into the pipe 7 and conveyed to the mixing unit 50.
回転体49は、ウェブVが混合部50に搬送される前に、ウェブVを切断(分断)することができる。図示の例では、回転体49は、基部49aと、基部49aから突出している突部49bと、を有している。突部49bは、例えば、板状の形状を有している。図示の例では、突部49bは4つ設けられ、4つの突部49bが等間隔に設けられている。基部49aが方向Rに回転することにより、突部49bは、基部49aを軸として回転することができる。回転体49によってウェブVを切断することにより、例えば、堆積部60に供給される単位時間当たりの解繊物の量の変動を小さくすることができる。
The rotating body 49 can cut (divide) the web V before the web V is transported to the mixing unit 50. In the example of illustration, the rotary body 49 has the base 49a and the protrusion 49b which protrudes from the base 49a. The protrusion 49 b has, for example, a plate-like shape. In the illustrated example, four protrusions 49 b are provided, and four protrusions 49 b are provided at equal intervals. By rotating the base 49 a in the direction R, the projection 49 b can rotate around the base 49 a. By cutting the web V by the rotating body 49, for example, it is possible to reduce the fluctuation of the amount of defibrated material supplied to the deposition unit 60 per unit time.
回転体49は、第1ウェブ形成部45の近傍に設けられている。図示の例では、回転体49は、ウェブVの経路において下流側に位置する張架ローラー47aの近傍に(張架ローラー47aの横に)設けられている。回転体49は、突部49bがウェブVと接触可能な位置であって、ウェブVが堆積されるメッシュベルト46と接触しない位置に設けられている。これにより、メッシュベルト46が突部49bによって磨耗する(破損する)ことを抑制することができる。突部49bとメッシュベルト46との間の最短距離は、例えば、0.05mm以上0.5mm以下である。突部49bとメッシュベルト46との間の最短距離が上記の範囲であれば、回転体49は、メッシュベルト46に損傷を与えることなくウェブVを切断することができる。
The rotating body 49 is provided in the vicinity of the first web forming unit 45. In the example of illustration, the rotary body 49 is provided in the vicinity of the tension roller 47a located in the downstream in the path | route of the web V (besides the tension roller 47a). The rotating body 49 is provided at a position where the projections 49 b can contact the web V and does not contact the mesh belt 46 on which the web V is deposited. As a result, the mesh belt 46 can be prevented from being worn out (broken) by the projections 49 b. The shortest distance between the protrusion 49 b and the mesh belt 46 is, for example, 0.05 mm or more and 0.5 mm or less. If the shortest distance between the projection 49 b and the mesh belt 46 is in the above range, the rotating body 49 can cut the web V without damaging the mesh belt 46.
混合部50は、選別部40を通過した第1選別物(第1ウェブ形成部45により搬送された第1選別物)と、樹脂を含む添加物と、を混合する。混合部50は、添加物を供給する添加物供給部52と、第1選別物と添加物とを搬送する管54と、ブロアー56と、を有している。図示の例では、添加物は、添加物供給部52からシューター9を介して管54に供給される。管54は、管7と連続している。
The mixing unit 50 mixes the first sorted matter (the first sorted matter conveyed by the first web forming unit 45) which has passed through the sorting unit 40 and the additive containing the resin. The mixing unit 50 includes an additive supply unit 52 for supplying an additive, a pipe 54 for transporting the first sorted matter and the additive, and a blower 56. In the illustrated example, the additive is supplied from the additive supply unit 52 to the pipe 54 via the shooter 9. The tube 54 is continuous with the tube 7.
混合部50では、ブロアー56によって気流を発生させ、管54中において、第1選別物と添加物とを混合させながら、搬送することができる。なお、第1選別物と添加物とを混合させる機構は、特に限定されず、高速回転する羽根により攪拌するものであってもよいし、V型ミキサーのように容器の回転を利用するものであってもよい。
In the mixing section 50, an air flow can be generated by the blower 56, and can be conveyed while mixing the first sorted matter and the additive in the pipe 54. The mechanism for mixing the first sorted matter and the additive is not particularly limited, and may be stirring with a blade rotating at a high speed, or using rotation of the container like a V-type mixer. It may be.
添加物供給部52としては、図8に示すようなスクリューフィーダーや、図示せぬディスクフィーダーなどを用いる。添加物供給部52から供給される添加物は、複数の繊維を結着させるための樹脂を含む。樹脂が供給された時点では、複数の繊維は結着されていない。樹脂は、シート形成部80を通過する際に溶融して、複数の繊維を結着させる。
As the additive supply unit 52, a screw feeder as shown in FIG. 8, a disc feeder (not shown) or the like is used. The additive supplied from the additive supply unit 52 includes a resin for binding a plurality of fibers. When the resin is supplied, the plurality of fibers are not bound. The resin is melted when passing through the sheet forming unit 80 to bind a plurality of fibers.
添加物供給部52から供給される樹脂は、熱可塑性樹脂や熱硬化性樹脂であり、例えば、AS樹脂、ABS樹脂、ポリプロピレン、ポリエチレン、ポリ塩化ビニル、ポリスチレン、アクリル樹脂、ポリエステル樹脂、ポリエチレンテレフタレート、ポリフェニレンエーテル、ポリブチレンテレフタレート、ナイロン、ポリアミド、ポリカーボネート、ポリアセタール、ポリフェニレンサルファイド、ポリエーテルエーテルケトン、などである。これらの樹脂は、単独または適宜混合して用いてもよい。添加物供給部52から供給される添加物は、繊維状であってもよく、粉末状であってもよい。
The resin supplied from the additive supply unit 52 is a thermoplastic resin or a thermosetting resin, and, for example, AS resin, ABS resin, polypropylene, polyethylene, polyvinyl chloride, polystyrene, acrylic resin, polyester resin, polyethylene terephthalate, Polyphenylene ether, polybutylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyether ether ketone, and the like. These resins may be used alone or in combination as appropriate. The additive supplied from the additive supply unit 52 may be fibrous or powdery.
なお、添加物供給部52から供給される添加物には、繊維を結着させる樹脂の他、製造されるシートの種類に応じて、繊維を着色するための着色剤や、繊維の凝集や樹脂の凝集を抑制するための凝集抑制剤 、繊維等を燃えにくくするための難燃剤が含まれていてもよい。混合部50を通過した混合物(第1選別物と添加物との混合物)は、管54を介して、堆積部60に移送される。
The additive supplied from the additive supply unit 52 includes, in addition to the resin for binding the fiber, a coloring agent for coloring the fiber, aggregation of the fiber, and resin depending on the type of sheet to be produced. A cohesion inhibitor for suppressing cohesion, and a flame retardant for making it difficult to burn fibers and the like may be contained. The mixture (mixture of the first sort and the additive) which has passed through the mixing section 50 is transferred to the deposition section 60 via the pipe 54.
堆積部60は、混合部50を通過した混合物を導入口62から導入し、絡み合った解繊物(繊維)をほぐして、空気中で分散させながら降らせる。さらに、堆積部60は、添加物供給部52から供給される添加物の樹脂が繊維状である場合、絡み合った樹脂をほぐす。これにより、堆積部60は、第2ウェブ形成部70に、混合物を均一性よく堆積させることができる。
The deposition unit 60 introduces the mixture having passed through the mixing unit 50 from the inlet 62, loosens the entangled disintegrated material (fiber), and causes the mixture to fall in the air while falling. Furthermore, if the resin of the additive supplied from the additive supply unit 52 is fibrous, the deposition unit 60 loosens the entangled resin. As a result, the deposition unit 60 can deposit the mixture uniformly on the second web forming unit 70.
堆積部60は、ドラム部(篩部)61と、ドラム部61を収容するハウジング部(覆い部)63と、を有している。ドラム部61としては、回転する円筒の篩を用いる。ドラム部61は、網を有し、混合部50を通過した混合物に含まれる、網の目開き(開口)の大きさより小さい繊維または粒子(網を通過するもの)を降らせる。ドラム部61の構成は、例えば、ドラム部41の構成と同じである。
The deposition unit 60 includes a drum unit (sieve unit) 61 and a housing unit (cover unit) 63 that accommodates the drum unit 61. As the drum unit 61, a sieve of a rotating cylinder is used. The drum unit 61 has a net, and lowers fibers or particles (that pass through the net) smaller than the size of the mesh opening (opening) contained in the mixture that has passed through the mixing unit 50. The configuration of the drum unit 61 is, for example, the same as the configuration of the drum unit 41.
なお、ドラム部61の「篩」は、特定の対象物を選別する機能を有していなくてもよい。すなわち、ドラム部61として用いられる「篩」とは、網を備えたもの、という意味であり、ドラム部61は、ドラム部61に導入された混合物の全てを降らしてもよい。
In addition, the "sieve" of the drum part 61 does not need to have a function which screens a specific target object. That is, the “sieve” used as the drum unit 61 means that the mesh unit is equipped with a net, and the drum unit 61 may lower all of the mixture introduced to the drum unit 61.
第2ウェブ形成部70は、堆積部60を通過した通過物を堆積して、ウェブWを形成する。第2ウェブ形成部70は、例えば、メッシュベルト72と、張架ローラー74と、サクション機構76と、を有している。
The second web forming unit 70 deposits the passing material that has passed through the depositing unit 60 to form the web W. The second web forming unit 70 includes, for example, a mesh belt 72, a tension roller 74, and a suction mechanism 76.
メッシュベルト72は、移動しながら、堆積部60の開口(網の開口)を通過した通過物を堆積する。メッシュベルト72は、張架ローラー74によって張架され、通過物を通しにくく空気を通す構成となっている。メッシュベルト72は、張架ローラー74が自転することによって移動する。メッシュベルト72が連続的に移動しながら、堆積部60を通過した通過物が連続的に降り積もることにより、メッシュベルト72上にウェブWが形成される。メッシュベルト72は、例えば、金属製、樹脂製、布製、あるいは不織布等である。
While moving, the mesh belt 72 deposits the passing material that has passed through the opening (opening of the net) of the deposition unit 60. The mesh belt 72 is stretched by a stretching roller 74 so as to make it difficult for the passing material to pass through and air to pass through. The mesh belt 72 moves as the tension roller 74 rotates. The web W is formed on the mesh belt 72 as the material passing through the stacking unit 60 is continuously deposited while the mesh belt 72 moves continuously. The mesh belt 72 is, for example, metal, resin, cloth, non-woven fabric, or the like.
サクション機構76は、メッシュベルト72の下方(堆積部60側とは反対側)に設けられている。サクション機構76は、下方に向く気流(堆積部60からメッシュベルト72に向く気流)を発生させることができる。サクション機構76によって、堆積部60により空気中に分散された混合物をメッシュベルト72上に吸引することができる。これにより、堆積部60からの排出速度を大きくすることができる。さらに、サクション機構76によって、混合物の落下経路にダウンフローを形成することができ、落下中に解繊物や添加物が絡み合うことを防ぐことができる。
The suction mechanism 76 is provided below the mesh belt 72 (opposite to the side of the deposition unit 60). The suction mechanism 76 can generate an air flow (air flow from the deposition unit 60 to the mesh belt 72) directed downward. The suction mechanism 76 can suction the mixture dispersed in the air by the deposition unit 60 onto the mesh belt 72. Thereby, the discharge speed from the deposition unit 60 can be increased. Furthermore, the suction mechanism 76 can form a downflow in the dropping path of the mixture, and can prevent entanglement of defibrated substances and additives during dropping.
以上のように、堆積部60および第2ウェブ形成部70(ウェブ形成工程)を経ることにより、空気を多く含み柔らかくふくらんだ状態のウェブWが形成される。メッシュベルト72に堆積されたウェブWは、シート形成部80へと搬送される。
As described above, by passing through the deposition section 60 and the second web formation section 70 (web formation process), the web W containing a large amount of air and in a soft and bloated state is formed. The web W deposited on the mesh belt 72 is conveyed to the sheet forming unit 80.
なお、図示の例では、ウェブWを調湿する調湿部(ウェブWを加湿する加湿部)78が設けられている。加湿部78は、ウェブWに対して水や水蒸気を添加して、ウェブWと水との量比を調節することができる。図示の例では、加湿部78は、メッシュベルト72の上方(堆積部60側)に設けられている。メッシュベルト72の下方(加湿部78側とは反対側)には、サクション機構78aが設けられている。サクション機構78aは、下方に向く(加湿部78からメッシュベルト72に向く)気流を発生させることができる。これにより、ウェブWを厚さ方向に均一性よく加湿することができる。
In the illustrated example, a humidity control unit (humidifying unit humidifying the web W) 78 that humidity-controls the web W is provided. The humidifying unit 78 can add water or steam to the web W to adjust the amount ratio of the web W to water. In the illustrated example, the humidifying unit 78 is provided above the mesh belt 72 (at the side of the deposition unit 60). A suction mechanism 78 a is provided below the mesh belt 72 (opposite to the side of the humidifying unit 78). The suction mechanism 78a can generate an air flow directed downward (directed from the humidifying unit 78 to the mesh belt 72). Thereby, the web W can be humidified with sufficient uniformity in the thickness direction.
また、図示の例では、メッシュベルト72上のウェブWを、シート形成部80に搬送する搬送部79が設けられている。搬送部79は、例えば、メッシュベルト79aと、張架ローラー79bと、サクション機構79c、を有している。サクション機構79cは、気流を発生させてウェブWを吸引し、メッシュベルト79aにウェブWを吸着させる。メッシュベルト79aは、張架ローラー79bの自転により移動し、ウェブWをシート形成部80に搬送する。メッシュベルト72の移動速度と、メッシュベルト79aの移動速度とは、例えば、同じである。
Further, in the illustrated example, a transport unit 79 that transports the web W on the mesh belt 72 to the sheet forming unit 80 is provided. The transport unit 79 includes, for example, a mesh belt 79a, a tension roller 79b, and a suction mechanism 79c. The suction mechanism 79c generates an air flow to suction the web W, and causes the mesh belt 79a to adsorb the web W. The mesh belt 79 a is moved by rotation of the tension roller 79 b and conveys the web W to the sheet forming unit 80. The moving speed of the mesh belt 72 and the moving speed of the mesh belt 79a are, for example, the same.
シート形成部80は、メッシュベルト72に堆積したウェブWを(堆積部60により堆積された堆積物を)加圧加熱してシートSを成形する。シート形成部80では、ウェブWにおいて混ぜ合された解繊物および添加物の混合物に、熱を加えることにより、混合物中の複数の繊維を、互いに添加物(樹脂)を介して結着することができる。
The sheet forming unit 80 forms the sheet S by pressurizing and heating the web W deposited on the mesh belt 72 (the deposit deposited by the depositing unit 60). In the sheet forming unit 80, heat is applied to the mixture of the defibrated material and the additive mixed in the web W to bind a plurality of fibers in the mixture to each other via the additive (resin). Can.
シート形成部80は、ウェブWを加圧する加圧部82と、加圧部82により加圧されたウェブWを加熱する加熱部84と、を備えている。加圧部82は、一対のカレンダーローラー85で構成され、ウェブWに対して圧力を加える。ウェブWは、加圧されることによりその厚さが小さくなり、ウェブWの密度が高められる。加熱部84としては、例えば、加熱ローラー(ヒーターローラー)、熱プレス成形機、ホットプレート、温風ブロアー、赤外線加熱器、フラッシュ定着器を用いる。図示の例では、加熱部84は、一対の加熱ローラー86を備えている。加熱部84を加熱ローラー86として構成することにより、加熱部84を板状のプレス装置(平板プレス装置)として構成する場合に比べて、ウェブWを連続的に搬送しながらシートSを成形することができる。ここで、カレンダーローラー85(加圧部82)は、加熱ローラー86(加熱部84)によってウェブWに印加される圧力よりも高い圧力をウェブWに印加することができる。なお、カレンダーローラー85や加熱ローラー86の数は、特に限定されない。
The sheet forming unit 80 includes a pressing unit 82 that presses the web W, and a heating unit 84 that heats the web W pressed by the pressing unit 82. The pressure unit 82 includes a pair of calendar rollers 85 and applies pressure to the web W. The pressure of the web W reduces its thickness, and the density of the web W is increased. As the heating unit 84, for example, a heating roller (heater roller), a heat press molding machine, a hot plate, a hot air blower, an infrared heater, and a flash fixing device are used. In the illustrated example, the heating unit 84 includes a pair of heating rollers 86. Forming the sheet S while conveying the web W continuously by configuring the heating unit 84 as the heating roller 86 as compared to the case where the heating unit 84 is configured as a plate-like pressing device (flat plate pressing device) Can. Here, the calendar roller 85 (pressure unit 82) can apply a pressure higher than the pressure applied to the web W by the heating roller 86 (heating unit 84) to the web W. The number of calender rollers 85 and heating rollers 86 is not particularly limited.
切断部90は、シート形成部80によって成形されたシートSを切断する。図示の例では、切断部90は、シートSの搬送方向と交差する方向にシートSを切断する第1切断部92と、搬送方向に平行な方向にシートSを切断する第2切断部94と、を有している。第2切断部94は、例えば、第1切断部92を通過したシートSを切断する。
The cutting unit 90 cuts the sheet S formed by the sheet forming unit 80. In the illustrated example, the cutting unit 90 includes a first cutting unit 92 for cutting the sheet S in a direction intersecting the conveyance direction of the sheet S, and a second cutting unit 94 for cutting the sheet S in a direction parallel to the conveyance direction. ,have. The second cutting unit 94 cuts, for example, the sheet S that has passed through the first cutting unit 92.
以上により、所定のサイズの単票のシートSが成形される。切断された単票のシートSは、排出部96へと排出される。
As described above, a single-cut sheet S of a predetermined size is formed. The cut single-cut sheet S is discharged to the discharge unit 96.
なお、シート製造装置500では、解繊部20を通過した解繊物は、管3を介して、分級部(図示せず)に移送されてもよい。そして、分級部において分級された分級物が、選別部40に搬送されてもよい。分級部は、解繊部20を通過した解繊物を分級する。具体的には、分級部は、解繊物の中で比較的小さいものや密度の低いもの(樹脂粒や色剤や添加剤など)を分離して除去する。これにより、解繊物の中で比較的大きいもしくは密度の高いものである繊維の占める割合を高めることができる。分級部としては、例えば、サイクロン、エルボージェット、エディクラシファイヤーなどを用いる。
In the sheet manufacturing apparatus 500, the defibrated material that has passed through the defibrating unit 20 may be transferred to the classification unit (not shown) via the pipe 3. Then, the classified material classified in the classification unit may be transported to the sorting unit 40. The classification unit classifies the defibrated material that has passed through the defibration unit 20. Specifically, the classified part separates and removes relatively small ones or low-density ones (resin particles, coloring agents, additives, etc.) among the defibrated materials. This makes it possible to increase the proportion of relatively large or dense fibers among the fibrillated materials. As a classification part, a cyclone, an elbow jet, an Eddy classifier, etc. are used, for example.
シート製造装置500によって製造されたシートSは、基材102として、自動的に読取部400に搬送されてもよいし、自動的に受容層形成部200に搬送されてもよい。
The sheet S manufactured by the sheet manufacturing apparatus 500 may be automatically transported to the reading unit 400 as the substrate 102, or may be automatically transported to the receiving layer forming unit 200.

例えば、ユーザーの端末装置から送信された印刷情報を印刷情報受信部110が受信すると、処理部120は処理を開始する。
For example, when the print information receiving unit 110 receives the print information transmitted from the terminal device of the user, the processing unit 120 starts processing.
まず、処理部120の基材状態判定部128は、基材102の状態を判定し、インク受容層104を形成するか否かを判定する(ステップS1)。具体的には、基材状態判定部128は、読取部400を制御して、基材102の表面をスキャンし、スキャン情報を取得する。そして、基材状態判定部128は、取得したスキャン情報に基づいて、基材102の状態を判定し、インク受容層104を形成するか否かを判定する。
First, the base material state determination unit 128 of the processing unit 120 determines the state of the base material 102 and determines whether to form the ink receiving layer 104 (step S1). Specifically, the base material state determination unit 128 controls the reading unit 400 to scan the surface of the base material 102 and acquire scan information. Then, the base material state determination unit 128 determines the state of the base material 102 based on the acquired scan information, and determines whether to form the ink receiving layer 104 or not.
ステップS1において基材状態判定部128が「インク受容層104を形成する」と判定した場合(ステップS1:Yes)、処理部120は、ステップS2の処理を行う。以降の処理は、上述の「1.2. 印刷方法」で説明したとおりである。
When the substrate state determination unit 128 determines that “the ink receiving layer 104 is to be formed” in step S1 (step S1: Yes), the processing unit 120 performs the process of step S2. The subsequent processing is as described above in “1.2. Printing method”.
ステップS1において基材状態判定部128が「インク受容層104を形成しない」と判定した場合(ステップS1:No)、処理部120は、処理を終了する。なお、処理部120は、「インク受容層104を形成しない」と判定された基材102をシート製造装置500に搬送するための処理を行った後に、処理を終了してもよい。
When the substrate state determination unit 128 determines that “the ink receiving layer 104 is not formed” in step S1 (step S1: No), the processing unit 120 ends the process. The processing unit 120 may end the processing after the processing for transporting the base material 102 determined to “do not form the ink receiving layer 104” to the sheet manufacturing apparatus 500.
