FIG. 1 is a schematic diagram showing the configuration of a sheet manufacturing apparatus 100.
片材製造裝置100將含有纖維之原料MA纖維化，執行再生成新的片材S之再生處理。片材製造裝置100可製造複數種片材S，亦可例如藉由對原料MA混合添加物，配合用途而附加片材S之結合強度或白度之調製、或顏色、香味、阻燃等功能。又，片材製造裝置100可調整片材S之密度或厚度、尺寸、形狀。作為片材S之代表例，除了A4或A3之標準尺寸之印刷用紙、地板掃除用片材等掃除用片材、油污用片材、廁所掃除用片材等片材狀製品外，舉出紙盤形狀等。片材製造裝置100相當於本發明之纖維原料再生裝置及纖維處理裝置。
The sheet manufacturing apparatus 100 fiberizes the fiber-containing raw material MA, and executes a regeneration process for regenerating a new sheet S. The sheet manufacturing apparatus 100 can manufacture a plurality of sheets S, and can also add the modulation of the bonding strength or whiteness of the sheet S, or the functions of color, fragrance, flame retardancy, etc., for example, by mixing additives to the raw material MA and matching the application. . In addition, the sheet manufacturing apparatus 100 can adjust the density, thickness, size, and shape of the sheet S. As a representative example of the sheet S, in addition to sheet-like products such as A4 or A3 standard-sized printing paper, floor cleaning sheets, and other sheet-like products such as oil stain sheets, toilet cleaning sheets, etc. Disk shape, etc. The sheet manufacturing device 100 corresponds to the fiber raw material regeneration device and fiber processing device of the present invention.
片材製造裝置100具備供給部10、粗碎部12、解纖部20、篩選部40、第1網片形成部45、旋轉體49、混合部50、堆積部60、第2網片形成部70、搬送部79、成形部80及切斷部90。粗碎部12、解纖部20、篩選部40及第1網片形成部45係構成將原料MA微細化而獲得片材S之材料之解纖處理部101。又，旋轉體49、混合部50、堆積部60、第2網片形成部70、成形部80及切斷部90係構成對以解纖處理部101獲得之材料進行處理而製造片材S之製造部102。
The sheet manufacturing apparatus 100 includes a supply unit 10, a coarse crushing unit 12, a defibrating unit 20, a screening unit 40, a first mesh forming unit 45, a rotating body 49, a mixing unit 50, a stacking unit 60, and a second mesh forming unit 70. The conveying part 79, the forming part 80, and the cutting part 90. The coarse portion 12, the defibrating portion 20, the screening portion 40, and the first mesh forming portion 45 constitute a defibrating processing portion 101 that obtains the material of the sheet S by miniaturizing the raw material MA. In addition, the rotating body 49, the mixing section 50, the accumulation section 60, the second mesh forming section 70, the forming section 80, and the cutting section 90 are configured to process the material obtained by the defibration processing section 101 to manufacture the sheet S Manufacturing Department 102.
供給部10係收容原料MA且對粗碎部12連續投入原料MA之自動投入裝置。原料MA只要為含有纖維者即可，例如為回收紙、廢紙、紙漿片材。
The supply unit 10 is an automatic feeding device that stores the raw material MA and continuously feeds the raw material MA to the coarse crushing unit 12. The raw material MA only needs to contain fibers, for example, recycled paper, waste paper, and pulp sheet.
粗碎部12具備將由供給部10供給之原料MA裁斷之粗碎刀14，將原料MA藉由粗碎刀14於空氣中裁斷，成為數cm見方之細片。細片之形狀及大小為任意。粗碎部12例如可使用碎紙機。由粗碎部12裁斷之原料MA由料斗9收集，經由管2被搬送至解纖部20。
The coarse crushing section 12 includes a coarse crushing knife 14 that cuts the raw material MA supplied from the supplying section 10, and the raw MA is cut in the air by the coarse crushing knife 14 into fine pieces of several cm square. The shape and size of the flakes are arbitrary. For the coarse shredder 12, for example, a paper shredder can be used. The raw material MA cut by the coarse crushing section 12 is collected by the hopper 9 and is transferred to the defibrating section 20 via the tube 2.
解纖部20對由粗碎部12裁斷之粗碎片進行解纖。所謂解纖是指將結著有複數條纖維之狀態之原料MA拆解成1條或少數條纖維之加工。原料MA亦可稱為被解纖物。藉由解纖部20將原料MA解纖，亦可期待使附著於原料MA之樹脂粒、墨水、增色劑、防滲劑等物質自纖維分離之效果。將通過解纖部20者稱為解纖物。解纖物中除了經拆解之解纖物纖維以外，亦可包含拆解纖維時自纖維分離之樹脂粒、墨水、增色劑等色劑、及防滲
材料、紙力增強劑等添加劑。解纖物所含之樹脂粒係於製造原料MA時用以使複數條纖維彼此結著而混合之樹脂。解纖物所含之纖維之形狀為串(string)狀或帶(ribbon)狀。解纖物所含之纖維亦可不與其他纖維交纏，而以獨立之狀態存在。或者，亦可與其他經拆解之解纖物交纏成塊狀，以形成所謂「團塊」之狀態存在。解纖部20相當於微細化部。又，後述之解纖物MB相當於微細化物。
The defibrating unit 20 defibrates coarse chips cut by the coarse crushing unit 12. The so-called defibration refers to the process of disassembling the raw material MA in which a plurality of fibers are bound into one or a few fibers. The raw material MA can also be called defibrated. By defibrating the raw material MA by the defibrating unit 20, the effect of separating resin particles, ink, color enhancer, impermeable agent, and other substances adhering to the raw material MA from the fiber can also be expected. Those passing through the defibrating unit 20 are called defibrating objects. In addition to the disassembled defibrated fiber, the defibrated material may also contain resin particles, ink, coloring agent and other colorants separated from the fiber when the fiber is disassembled, and anti-seepage
Additives such as materials and paper strength enhancers. The resin particles contained in the defibrated material are resins used to bind and mix a plurality of fibers with each other when manufacturing the raw material MA. The shape of the fibers contained in the defibrated material is string or ribbon. The fibers contained in the defibrated material can also exist in an independent state without being entangled with other fibers. Alternatively, it can be intertwined with other dismantled defibrating objects to form a so-called "clump". The defibrating unit 20 corresponds to a miniaturization unit. In addition, the defibrating material MB described later corresponds to a finely divided material.
解纖部20以乾式進行解纖。所謂乾式是指不於液體中而是於大氣中(空氣中)等氣體中進行解纖等處理。解纖部20例如可使用葉輪粉碎機等解纖機構成。具體而言，解纖部20具備旋轉之轉子(省略圖示)、及位於轉子(省略圖示)之外周之襯墊(省略圖示)，將粗碎片夾於轉子與襯墊之間進行解纖。
The defibrating unit 20 performs defibrating in a dry manner. The so-called dry type means that the treatment of defibration and the like is carried out in a gas such as the atmosphere (in the air) not in the liquid. The defibrating unit 20 can be configured using a defibrating machine such as an impeller pulverizer. Specifically, the defibrating unit 20 includes a rotating rotor (not shown) and a spacer (not shown) located on the outer periphery of the rotor (not shown), and sandwiches coarse debris between the rotor and the spacer for decompression Fiber.
將粗碎片藉由氣流自粗碎部12搬送至解纖部20。可為由解纖部20產生該氣流之構成，亦可於粗碎片或解纖物之搬送方向上之解纖部20之上游或下游側設置鼓風機(省略圖示)而使氣流產生。又，將解纖物藉由氣流自解纖部20經由管3移送至篩選部40。將解纖物搬送至篩選部40之氣流可由解纖部20產生，亦可利用上述鼓風機之氣流。
The coarse fragments are transferred from the coarse crushing section 12 to the defibrating section 20 by airflow. The air flow may be generated by the defibrating unit 20, or a blower (not shown) may be provided on the upstream or downstream side of the defibrating unit 20 in the conveying direction of coarse debris or defibrated material to generate airflow. In addition, the defibrated material is transferred from the defibrating unit 20 to the screening unit 40 via the tube 3 by airflow. The airflow that transports the defibrated material to the screening section 40 can be generated by the defibrating section 20, or the airflow of the blower described above can be used.
篩選部40根據纖維之尺寸而篩選由解纖部20解纖後之解纖物中所含之成分。纖維之尺寸主要是指纖維之長度。篩選部40具有對筒部41導入解纖物之導入口42、及自筒部41排出後述之第2篩選物之排出口44。排出口44藉由管8而連接於解纖部20，篩選部40將第2篩選物通過管8回送至解
纖部20。
The screening unit 40 screens the components contained in the defibrated fiber defibrated by the defibrating unit 20 according to the size of the fiber. The size of the fiber mainly refers to the length of the fiber. The screening unit 40 has an introduction port 42 for introducing the defibrated material into the tube unit 41 and a discharge port 44 for discharging a second screening product to be described later from the tube unit 41. The discharge port 44 is connected to the defibrating unit 20 through the tube 8, and the screening unit 40 returns the second screening material to the defibration through the tube 8

As shown in FIGS. 1 and 2, the screening unit 40 has a cylindrical portion 41 and a shell portion 43 that accommodates the cylindrical portion 41.
筒部41例如使用篩而構成。具體而言，筒部41具備具有開口而作為篩發揮功能之網、過濾器、網篩等。具體而言，筒部41為圓筒形狀，藉由第1篩馬達40a(驅動部、篩驅動部)，以圓筒之軸為中心而被旋轉驅動。筒部41之周面之至少一部分為網。筒部41之網係以將金網、具有刻痕之金屬板加以延展之金屬網、衝孔金屬板等構成。圖2中以符號41a表示筒部41之開口。將筒部41藉由第1篩馬達40a之動力而動作之動作速度設為速度VB。速度VB亦可稱為筒部41之旋轉速度。另，筒部41之旋轉方向不限於圖2所示之方向，可為反方向，亦可藉由第1篩馬達40a切換旋轉方向而進行往返動作。速度VB不限於圖2之箭頭所示方向之速度，其係指相對於靜止狀態之筒部41之相對速度。
The cylindrical portion 41 is configured using, for example, a sieve. Specifically, the cylindrical portion 41 includes a mesh, a filter, a mesh screen, and the like having an opening and functioning as a screen. Specifically, the cylindrical portion 41 has a cylindrical shape, and is driven to rotate about the axis of the cylinder by the first sieve motor 40a (driving portion, sieve driving portion). At least a part of the circumferential surface of the cylindrical portion 41 is a net. The mesh of the barrel portion 41 is composed of a metal mesh expanded by a gold mesh, a metal sheet with a score, a punched metal sheet, and the like. In FIG. 2, the opening of the cylindrical portion 41 is indicated by a symbol 41a. The operating speed at which the cylindrical portion 41 is operated by the power of the first sieve motor 40a is defined as the speed VB. The speed VB may also be referred to as the rotation speed of the cylinder 41. In addition, the rotation direction of the cylindrical part 41 is not limited to the direction shown in FIG. 2, it may be a reverse direction, and the rotation direction may be switched by the first sieve motor 40a to perform a reciprocating operation. The speed VB is not limited to the speed indicated by the arrow in FIG. 2, and refers to the relative speed with respect to the cylindrical portion 41 in the stationary state.
筒部41相當於本發明之篩部。又，被導入至筒部41之解纖物MB及通過開口41a篩選出之第1篩選物MC相當於材料。
The cylindrical part 41 corresponds to the screen part of this invention. In addition, the defibrated material MB introduced into the cylindrical portion 41 and the first screening material MC screened through the opening 41a correspond to materials.
第1網片形成部45具備網帶46、張力輥47及抽吸部48。網帶46為環形狀之金屬製帶，架設於複數個張力輥47。網帶46環繞由張力輥47構成
之軌道。網帶46之軌道之一部分在筒部41之下方為平坦，網帶46構成平坦面。
The first mesh forming portion 45 includes a mesh belt 46, a tension roller 47, and a suction portion 48. The mesh belt 46 is a ring-shaped metal belt, which is erected on a plurality of tension rollers 47. The mesh belt 46 is surrounded by a tension roller 47
Track. A part of the track of the mesh belt 46 is flat below the cylindrical portion 41, and the mesh belt 46 constitutes a flat surface.
張力輥47中之一者為驅動網帶46之驅動輥47a。驅動輥47a由第1帶馬達47b驅動而旋轉，於圖中箭頭所示之方向驅動網帶46。將網帶46藉由第1帶馬達47b之驅動力而動作之動作速度設為速度VA。速度VA亦可稱為網帶46之搬送速度。
One of the tension rollers 47 is a driving roller 47a that drives the mesh belt 46. The driving roller 47a is driven to rotate by the first belt motor 47b, and drives the mesh belt 46 in the direction indicated by the arrow in the figure. The operating speed at which the mesh belt 46 is operated by the driving force of the first belt motor 47b is set to the speed VA. The speed VA may also be referred to as the conveying speed of the mesh belt 46.
對於第1篩馬達40a及第1帶馬達47b，可使用伺服馬達、步進馬達等眾所周知之馬達。亦可於第1篩馬達40a與筒部41之間，設置傳達動力之齒輪、連桿等其他傳達機構。驅動輥47a與第1帶馬達47b之間亦同。
For the first screen motor 40a and the first belt motor 47b, well-known motors such as a servo motor and a stepping motor can be used. Other transmission mechanisms such as gears and connecting rods that transmit power may be provided between the first sieve motor 40a and the cylindrical portion 41. The same is true between the driving roller 47a and the first belt motor 47b.
自導入口42被導入至筒部41之內部之解纖物MB藉由筒部41之旋轉，而分成通過筒部41之開口41a之通過物及未通過開口41a之殘留物。通過開口41a之通過物含有小於開口41a之纖維或粒子，將其設為第1篩選物，以符號MC表示。殘留物含有大於開口41a之纖維、未解纖片或團塊，將其稱為第2篩選物。第1篩選物MC於殼部43內之內部向第1網片形成部45下降。第2篩選物如上述，藉由管8自排出口44搬送至解纖部20。篩選部40相當於分離部。
The defibrated material MB introduced into the inside of the cylindrical portion 41 from the introduction port 42 is divided into a passing object passing through the opening 41 a of the cylindrical portion 41 and a residue not passing through the opening 41 a by the rotation of the cylindrical portion 41. The passage material passing through the opening 41a contains fibers or particles smaller than the opening 41a, and this is designated as the first screening material and is indicated by the symbol MC. The residue contains fibers, undefibrated sheets or agglomerates larger than the opening 41a, and this is called the second screen. The first screening substance MC descends to the first mesh forming part 45 inside the shell 43. As described above, the second screening material is transported from the discharge port 44 to the defibrating unit 20 through the tube 8. The screening unit 40 corresponds to the separation unit.
藉由筒部41之旋轉，通過開口41a之第1篩選物MC於殼部43之內部向網帶46下降。於網帶46形成有多個開口。自筒部41下降之第1篩選物MC中，大於網帶46之開口之成分堆積於網帶46。又，第1篩選物MC中小於
網帶46之開口之成分通過開口。將通過網帶46之開口之成分設為第3篩選物D。第3篩選物D包含解纖物所含之纖維中短於網帶46之開口之纖維，或含有藉由解纖部20自纖維分離之樹脂粒、墨水、增色劑、防滲劑等之粒子。網帶46相當於本發明之堆積部。
By the rotation of the cylindrical portion 41, the first screening substance MC passing through the opening 41a descends to the mesh belt 46 inside the shell portion 43. A plurality of openings are formed in the mesh belt 46. In the first screening substance MC descending from the cylindrical portion 41, components larger than the opening of the mesh belt 46 accumulate on the mesh belt 46. In addition, the first screen MC is less than
The component of the opening of the mesh belt 46 passes through the opening. Let the component passing through the opening of the mesh belt 46 be the third screening substance D. The third screening substance D contains fibers shorter than the opening of the mesh belt 46 among the fibers contained in the defibrating material, or particles containing resin particles, ink, color enhancer, impermeable agent, etc. separated from the fibers by the defibrating portion 20 . The mesh belt 46 corresponds to the accumulation portion of the present invention.
抽吸部48可自網帶46之下方抽吸空氣。抽吸部48經由管23連結於第1集塵部27。第1集塵部27具有將第3篩選物自氣流分離之過濾器。於第1集塵部27之下游，設置第1捕集鼓風機28，第1捕集鼓風機28自第1集塵部27抽吸空氣。
The suction part 48 can suck air from below the mesh belt 46. The suction part 48 is connected to the first dust collecting part 27 via the tube 23. The first dust collector 27 has a filter that separates the third screening material from the airflow. Downstream of the first dust collecting part 27, a first collecting blower 28 is provided, and the first collecting blower 28 sucks air from the first dust collecting part 27.
藉由該構成，將下降至網帶46之第1篩選物MC中尺寸較小之第3篩選物D藉由第1捕集鼓風機28之抽吸力抽吸，且藉由第1集塵部27之過濾器而捕集。通過第1集塵部27之過濾器之空氣藉由管29排出。
With this configuration, the third filter D having a smaller size among the first filters MC dropped to the mesh belt 46 is sucked by the suction force of the first trapping blower 28, and passed through the first dust collector 27 filters. The air passing through the filter of the first dust collecting part 27 is discharged through the tube 29.
藉由吸引部48抽吸之氣流，將自筒部41下降之第1篩選物MC朝網帶46吸引，故有促進堆積之效果。
The airflow sucked by the suction part 48 attracts the first screening substance MC descending from the cylinder part 41 toward the mesh belt 46, so that it has an effect of promoting accumulation.
堆積於網帶46之第1篩選物MC成為網形狀，構成第1網片W1。
The first screening material MC deposited on the mesh belt 46 has a mesh shape and constitutes a first mesh W1.
第1網片W1係以第1篩選物所含之成分中大於網帶46之開口之纖維為主要成分，形成為包含較多空氣之柔軟膨脹狀態。第1網片W1隨著網帶46之移動被搬送至旋轉體49。
The first mesh W1 is composed of fibers larger than the opening of the mesh belt 46 among the components contained in the first screening material, and is formed into a soft expanded state containing a large amount of air. The first mesh W1 is transported to the rotating body 49 as the mesh belt 46 moves.
返回至圖1，旋轉體49具備連結於馬達等驅動部(省略圖示)之基部49a、及自基部49a突出之突部49b，藉由基部49a於方向R旋轉，突部49b
以基部49a為中心而旋轉。突部49b例如具有板狀之形狀。圖1之例中，於基部49a等間隔設有4個突部49b。
Returning to FIG. 1, the rotating body 49 includes a base 49a connected to a driving portion (not shown) such as a motor, and a protrusion 49b protruding from the base 49a. The protrusion 49b is rotated in the direction R by the base 49a
Rotates around the base 49a. The protrusion 49b has a plate shape, for example. In the example of FIG. 1, four protrusions 49b are provided at equal intervals on the base 49a.
旋轉體49位於網帶46之軌道中平坦部分之端部。在該端部，由於網帶46之軌道向下方彎曲，故網帶46向下方彎曲而移動。因此，網帶46所搬送之第1網片W1自網帶46突出，與旋轉體49接觸。第1網片W1藉由突部49b與第1網片W1碰撞而被拆解，成為小纖維塊。該塊通過位於旋轉體49下方之管7，被搬送至混合部50。第1網片W1如上述，為纖維堆積於網帶46而形成之柔軟構造，與旋轉體49碰撞時容易被分斷。
The rotating body 49 is located at the end of the flat part in the track of the mesh belt 46. At this end, since the rail of the mesh belt 46 bends downward, the mesh belt 46 bends downward and moves. Therefore, the first mesh W1 carried by the mesh belt 46 protrudes from the mesh belt 46 and comes into contact with the rotating body 49. The first mesh W1 is disassembled by the protrusion 49b colliding with the first mesh W1, and becomes a small fiber block. This block is transferred to the mixing unit 50 through the tube 7 located below the rotating body 49. As described above, the first mesh W1 is a soft structure formed by fibers deposited on the mesh belt 46, and is easily broken when it collides with the rotating body 49.
旋轉體49之位置為突部49b可與第1網片W1接觸之位置，突部49b設置於不與網帶46接觸之位置。突部49b與網帶46最接近之位置處之相互間之距離較佳設為例如0.05mm以上0.5mm以下。
The position of the rotating body 49 is a position where the protrusion 49b can contact the first mesh W1, and the protrusion 49b is provided at a position where it does not contact the mesh belt 46. The distance between the protrusion 49b and the mesh belt 46 at the closest position is preferably set to, for example, 0.05 mm or more and 0.5 mm or less.

The additive supply part 52 is provided with an additive cassette 52a for storing additive. The additive cassette 52a may be detachable to the additive supply unit 52. The additive supply unit 52 includes an additive extraction unit 52b that takes out the additive from the additive cassette 52a, and an additive input unit 52c that discharges the additive taken out by the additive extraction unit 52b to the tube 54. The additive supply part 52b is equipped with a feeder that successively feeds out additives containing fine powder or fine particles inside the additive cassette 52a (omitted figure)
Shown), the additive is taken out from a part or all of the additive cassette 52a. The additive taken out by the additive taking part 52b is sent to the additive putting part 52c. The additive input part 52c accommodates the additive extracted by the additive extraction part 52b. The additive input part 52c is provided with a shutter (not shown) that can be opened and closed at the connecting part with the tube 54, and by opening the barrier, the additive taken out by the additive extraction part 52b is sent to the tube 54.
自添加物供給部52供給之添加物包含用以使複數條纖維結著之樹脂(結著劑)。添加物所含之樹脂通過成形部80時熔融，使複數條纖維結著。該樹脂為熱塑性樹脂或熱硬化性樹脂，例如為AS樹脂、ABS樹脂、聚丙烯、聚乙烯、聚氯乙烯、聚苯乙烯、丙烯酸樹脂、聚酯纖維樹脂、聚對苯二甲酸乙二酯、聚苯醚、聚對苯二甲酸丁二醇酯、尼龍、聚醯胺、聚碳酸酯、聚縮醛、聚苯硫醚、聚醚醚酮等。該等樹脂可單獨使用，亦可適當混合使用。

示)之構成，亦可為連結葉片與盒體之構成。又，混合鼓風機56除了使氣流產生之葉片以外，亦可具備使第1篩選物與添加物混合之混合器。以混合部50混合之混合物藉由混合鼓風機56產生之氣流被搬送至堆積部60，且被導入至堆積部60之導入口62。
The mixing blower 56 generates air flow in the tube 54 connecting the tube 7 and the accumulation part 60. In addition, the first screening substance transported from the tube 7 to the tube 54 and the additive supplied to the tube 54 by the additive supply unit 52 are mixed when passing through the mixing blower 56. The hybrid blower 56 can be provided with, for example, a motor (not shown), a blade driven by the motor (not shown), and a box containing the blade (not shown)
The structure shown) may also be a structure connecting the blade and the box body. In addition, the mixing blower 56 may be equipped with a mixer that mixes the first screening substance and the additive in addition to the blade that generates the air flow. The airflow generated by the mixing blower 56 of the mixture mixed by the mixing section 50 is transported to the accumulation section 60 and introduced into the introduction port 62 of the accumulation section 60.
堆積部60將混合物之纖維拆解，使其一面於空氣中分散一面下降至第2網片形成部70。自添加物供給部52供給之添加物為纖維狀之情形時，該等纖維亦於堆積部60被拆解，下降至第2網片形成部70。第2網片形成部70使自堆積部60下降之混合物堆積，形成第2網片W2。
The accumulation part 60 disassembles the fibers of the mixture, and lowers the fibers of the mixture to the second mesh forming part 70 while being dispersed in the air. When the additive supplied from the additive supply part 52 is fibrous, the fibers are also disassembled in the accumulation part 60 and descend to the second mesh forming part 70. The second mesh forming portion 70 accumulates the mixture lowered from the accumulating portion 60 to form the second mesh W2.
圖3係顯示堆積部60及第2網片形成部70之概略構成之圖，為要部側視圖。
FIG. 3 is a diagram showing a schematic configuration of the accumulation part 60 and the second mesh forming part 70, and is a side view of the main part.
如圖1及圖3所示，堆積部60具有筒部61及收容筒部61之殼部63。
As shown in FIGS. 1 and 3, the accumulation portion 60 has a cylindrical portion 61 and a shell portion 63 that accommodates the cylindrical portion 61.
堆積部60具有筒部61及收容筒部61之殼部63。筒部61為構成之圓筒形狀之構造體。圖3係以符號61a表示筒部61之開口。
The accumulation portion 60 has a cylindrical portion 61 and a shell portion 63 that accommodates the cylindrical portion 61. The cylindrical portion 61 is a cylindrical structure. In FIG. 3, the opening of the cylindrical portion 61 is indicated by a symbol 61a.
筒部61例如與筒部61同樣地，使用篩而構成。具體而言，筒部61具備具有開口而作為篩發揮功能之網、過濾器、網篩等。具體而言，筒部61為圓筒形狀，藉由第2篩馬達60a(驅動部、篩驅動部)，以圓筒之軸為中心而被旋轉驅動。筒部61之周面之至少一部分為網。筒部61之網係以將金網、具有刻痕之金屬板加以延展之金屬網、衝孔金屬板等構成。筒部61藉由第2篩馬達60a之動力而旋轉，作為篩發揮功能，供藉由筒部61之旋轉
而被拆解之混合物通過開口61a而下降。此處，將自導入口62導入之混合物以符號MX表示。
The cylindrical portion 61 is configured using a sieve, for example, similar to the cylindrical portion 61. Specifically, the cylindrical portion 61 includes a mesh, a filter, a mesh screen, and the like having an opening and functioning as a screen. Specifically, the cylindrical portion 61 has a cylindrical shape, and is driven to rotate about the axis of the cylinder by the second sieve motor 60a (driving portion, sieve driving portion). At least a part of the circumferential surface of the cylindrical portion 61 is a net. The mesh of the barrel portion 61 is composed of a metal mesh expanded by a gold mesh, a metal plate with a score, a punched metal plate, and the like. The cylindrical portion 61 is rotated by the power of the second sieve motor 60a and functions as a sieve for rotation by the cylindrical portion 61
The disassembled mixture descends through the opening 61a. Here, the mixture introduced from the introduction port 62 is represented by the symbol MX.
將筒部61藉由第2篩馬達60a之動力而動作之動作速度設為速度VD。速度VD亦可稱為筒部61之旋轉速度。另，筒部61之旋轉方向不限於圖3所示之方向，可為反方向，亦可藉由第2篩馬達60a切換旋轉方向而進行往返動作。速度VD不限於圖3之箭頭所示方向之速度，其係指相對於靜止狀態之筒部61之相對速度。
The operating speed at which the cylindrical portion 61 is operated by the power of the second screen motor 60a is referred to as the speed VD. The speed VD may also be referred to as the rotation speed of the cylinder 61. In addition, the rotation direction of the cylindrical part 61 is not limited to the direction shown in FIG. 3, and may be the reverse direction, and the rotation direction may be switched by the second sieve motor 60a to perform the reciprocating operation. The speed VD is not limited to the speed indicated by the arrow in FIG. 3, but refers to the relative speed with respect to the cylindrical portion 61 in the stationary state.
於筒部61之下方配置第2網片形成部70。第2網片形成部70具有例如網帶72、張力輥74、及抽吸機構76。
The second mesh forming portion 70 is arranged below the cylindrical portion 61. The second mesh forming portion 70 includes, for example, a mesh belt 72, a tension roller 74, and a suction mechanism 76.
網帶72係以與網帶46相同之環形狀之金屬製帶構成，架設於複數個張力輥74。網帶72環繞由張力輥74構成之軌道。網帶72之軌道之一部分在筒部61之下方為平坦，網帶72構成平坦面。又，於網帶72形成有多個開口。
The mesh belt 72 is formed of a metal belt having the same loop shape as the mesh belt 46, and is erected on a plurality of tension rollers 74. The mesh belt 72 surrounds the track formed by the tension roller 74. A part of the track of the mesh belt 72 is flat below the cylindrical portion 61, and the mesh belt 72 constitutes a flat surface. In addition, a plurality of openings are formed in the mesh belt 72.
張力輥74中之一者為驅動網帶72之驅動輥74a。驅動輥74a由第2帶馬達74b驅動而旋轉，於圖中箭頭所示方向驅動網帶72。將網帶72藉由第2帶馬達74b之驅動力而動作之動作速度設為速度VC。速度VC亦可稱為網帶72之搬送速度。
One of the tension rollers 74 is a driving roller 74a that drives the mesh belt 72. The driving roller 74a is driven to rotate by the second belt motor 74b, and drives the mesh belt 72 in the direction indicated by the arrow in the figure. The operating speed at which the mesh belt 72 is operated by the driving force of the second belt motor 74b is defined as the speed VC. The speed VC may also be referred to as the conveying speed of the mesh belt 72.
對於第2篩馬達60a及第2帶馬達74b，可使用伺服馬達、步進馬達等
眾所周知之馬達。亦可於第2篩馬達60a與筒部61之間，設置傳達動力之齒輪、連桿等其他傳達機構。驅動輥74a與第2帶馬達74b之間亦同。
For the second screen motor 60a and the second belt motor 74b, a servo motor, a stepping motor, etc. can be used
Well-known motor. Other transmission mechanisms such as gears and connecting rods for transmitting power may be provided between the second screen motor 60a and the cylinder 61. The same is true between the driving roller 74a and the second belt motor 74b.
藉由筒部61之旋轉，筒部61內部之混合物MX通過開口61a，向網帶72下降。自筒部61下降之混合物MX中大於網帶72之開口之成分堆積於網帶72。又，混合物中小於網帶72之開口之成分通過開口。
By the rotation of the cylinder 61, the mixture MX inside the cylinder 61 passes through the opening 61a and descends toward the mesh belt 72. The components of the mixture MX descending from the cylinder 61 that are larger than the opening of the mesh belt 72 accumulate on the mesh belt 72. In addition, components in the mixture smaller than the opening of the mesh belt 72 pass through the opening.
抽吸機構76連接於管66。管66經由第2集塵部67而連接於第2捕集鼓風機68。第2集塵部67具備捕集通過網帶72之粒子或纖維之過濾器。第2捕集鼓風機68為抽吸通過管66之空氣之鼓風機，將抽吸之空氣排出至片材製造裝置100之外部，或片材製造裝置100內之特定位置。抽吸機構76藉由第2捕集鼓風機68之抽吸力，自網帶72之下方抽吸空氣，藉由第2集塵部67捕集抽吸之空氣中所含之粒子或纖維。第2捕集鼓風機68抽吸之氣流將自筒部61下降之混合物朝網帶72吸引，有促進堆積之效果。又，第2捕集鼓風機68之抽吸氣流於混合物自筒部61落下之路徑形成降流，亦可期待防止纖維於落下過程中交纏之效果。堆積於網帶72之混合物MX於網帶72之平坦部成為網形狀，構成第2網片W2。
The suction mechanism 76 is connected to the tube 66. The tube 66 is connected to the second collecting blower 68 via the second dust collecting part 67. The second dust collector 67 includes a filter that collects particles or fibers that pass through the mesh belt 72. The second trapping blower 68 is a blower that sucks air passing through the tube 66, and discharges the sucked air to the outside of the sheet manufacturing apparatus 100, or a specific position within the sheet manufacturing apparatus 100. The suction mechanism 76 sucks air from below the mesh belt 72 by the suction force of the second collecting blower 68, and collects particles or fibers contained in the sucked air by the second dust collecting part 67. The airflow sucked by the second collecting blower 68 draws the mixture descending from the cylindrical portion 61 toward the mesh belt 72, which has an effect of accelerating accumulation. In addition, the suction airflow of the second collecting blower 68 forms a downflow on the path where the mixture falls from the cylindrical portion 61, and the effect of preventing the entanglement of fibers during the falling process can also be expected. The mixture MX deposited on the mesh belt 72 becomes a mesh shape at the flat portion of the mesh belt 72, and constitutes the second mesh W2.
返回至圖1，網帶72之搬送路徑中，於堆積部60之下游側設置調濕部78。調濕部78為將水變成霧狀而向網帶72供給之霧式加濕器。調濕部78例如具備貯存水之槽，或將水變成霧狀之超音波振子。由於藉由調濕部78供給之水霧來調整第2網片W2之水分含量，故可期待抑制纖維因靜電而向網帶72吸附等之效果。
Returning to FIG. 1, in the conveyance path of the mesh belt 72, a humidity control section 78 is provided on the downstream side of the accumulation section 60. The humidity control unit 78 is a mist humidifier that supplies water to the mesh belt 72 into a mist. The humidity control unit 78 includes, for example, a tank for storing water, or an ultrasonic transducer that turns water into mist. Since the moisture content of the second mesh W2 is adjusted by the water mist supplied from the humidity control unit 78, the effect of suppressing the attraction of the fibers to the mesh belt 72 due to static electricity can be expected.
第2網片W2藉由搬送部79自網帶72剝離，並向成形部80搬送。搬送部79具有例如網帶79a、輥79b、及抽吸機構79c。抽吸機構79c具備鼓風機(省略圖示)，藉由鼓風機之抽吸力，而通過網帶79a產生朝上之氣流。藉由該氣流，第2網片W2自網帶72分離而被吸附於網帶79a。網帶79a藉由輥79b之旋轉而移動，將第2網片W2搬送至成形部80。
The second mesh W2 is peeled off from the mesh belt 72 by the transport unit 79 and transported to the forming unit 80. The transport unit 79 has, for example, a mesh belt 79a, a roller 79b, and a suction mechanism 79c. The suction mechanism 79c includes a blower (not shown), and the suction force of the blower generates upward airflow through the mesh belt 79a. With this airflow, the second mesh W2 is separated from the mesh belt 72 and is attracted to the mesh belt 79a. The mesh belt 79a moves by the rotation of the roller 79b, and conveys the second mesh W2 to the forming section 80.
成形部80藉由對第2網片W2施加熱，而使第2網片W2所含之來自第1篩選物之纖維藉由添加物所含之樹脂而結著。
The molding section 80 applies heat to the second mesh W2, so that the fibers from the first screen contained in the second mesh W2 are bound by the resin contained in the additive.

The forming section 80 includes a pressing section 82 that presses the second mesh W2, and a heating section 84 that heats the second mesh W2 pressed by the pressing section 82. The pressing portion 82 is composed of a pair of calender rollers 85 and 85. The pressing section 82 is connected to a driving mechanism such as a pressing mechanism (not shown) that applies nip pressure to the calender rolls 85 and 85 by hydraulic pressure, and a driving section such as a motor that rotates the calender rolls 85 and 85 toward the heating section 84 ( (Not shown). The pressing unit 82 presses the second mesh W2 with the specific nip pressure by the calender rollers 85 and 85 and transports it to the heating unit 84. The heating section 84 includes a pair of heating rollers 86 and 86. The heating unit 84 includes: a heater (not shown) that heats the peripheral surface of the heating roller 86 to a specific temperature; and a driving unit (not shown) such as a motor that rotates the heating rollers 86 and 86 toward the cutting unit 90 . The heating section 84 applies heat while sandwiching the second mesh W2 whose density is increased by the pressing section 82, and is transported to the cutting section 90. The second mesh W2 is heated in the heating section 84 to a higher temperature than the glass transition point of the resin contained in the second mesh W2, and becomes the sheet S.
切斷部90將以成形部80成形之片材S切斷。切斷部90具有第1切斷部92，其沿著圖中符號F所示之與片材S之搬送方向交叉之方向將片材S切
斷；及第2切斷部94，其在與搬送方向F平行之方向將片材S切斷。切斷部90將片材S之長度及寬度切割成特定尺寸，形成單片之片材S。以切斷部90切割之片材被收容於排出部96。排出部96具備收容製造出之片材之托盤或堆料機，排出至托盤之片材S可由使用者取出使用。
The cutting section 90 cuts the sheet S formed by the forming section 80. The cutting section 90 has a first cutting section 92 which cuts the sheet S in a direction crossing the conveying direction of the sheet S as indicated by symbol F in the figure
Off; and the second cutting portion 94, which cuts the sheet S in a direction parallel to the conveying direction F. The cutting section 90 cuts the length and width of the sheet S into a specific size to form a single sheet S. The sheet cut by the cutting unit 90 is stored in the discharge unit 96. The discharge section 96 is provided with a tray or a stacker that houses the manufactured sheets, and the sheets S discharged to the tray can be taken out and used by the user.

[1-2.第1網片之形成條件]
[1-2. Conditions for forming the first mesh sheet]
此處，參照圖2，針對以第1網片形成部45形成之第1網片W1之形成條件進行說明。
Here, referring to FIG. 2, the forming conditions of the first mesh W1 formed by the first mesh forming portion 45 will be described.
第1網片W1之厚度係根據供給於網帶46之材料即第1篩選物MC之量、及網帶46之每單位時間之移動量而決定。網帶46之每單位時間之移動量為圖中之速度VA。
The thickness of the first mesh W1 is determined according to the amount of the first screening material MC supplied to the mesh belt 46 and the amount of movement of the mesh belt 46 per unit time. The movement amount of the mesh belt 46 per unit time is the speed VA in the figure.
作為決定供給於網帶46之第1篩選物MC之量、即通過開口41a之第1篩選物MC之量之要素，可舉出速度VB。速度VB愈高速，解纖物MB在筒部41內愈被快速拆解，第1篩選物MC易通過開口41a。又，速度VB愈高速，第1篩選物MC愈易通過開口41a。因此，速度VB愈快，通過開口41a之第1篩選物MC之量愈多。
As an element that determines the amount of the first screen MC supplied to the mesh belt 46, that is, the amount of the first screen MC passing through the opening 41a, the speed VB can be cited. The faster the speed VB is, the more quickly the defibrating material MB is disassembled in the cylindrical portion 41, and the first screening material MC easily passes through the opening 41a. In addition, the higher the speed VB, the easier the first screen MC passes through the opening 41a. Therefore, the faster the speed VB, the greater the amount of the first screen MC passing through the opening 41a.
通過開口41a之第1篩選物MC之量會於筒部41自停止狀態啟動時變動。於筒部41內，由於藉由筒部41之旋轉而於第1篩選物MC所含之纖維與纖維之間產生摩擦，故第1篩選物MC帶電。若第1篩選物MC因該靜電而凝集，則不易通過開口41a。另一方面，筒部41停止期間，因帶電之第1篩選物MC之電荷放電，故第1篩選物MC所含之纖維之凝集被解開。因此，筒部41自停止狀態開始旋轉時，即啟動時，第1篩選物MC為易通過開口41a之狀態。在此種狀態下，通過開口41a之第1篩選物MC之量會暫時變多。
The amount of the first screening substance MC passing through the opening 41a changes when the cylindrical portion 41 is started from the stopped state. In the cylindrical portion 41, the rotation between the cylindrical portion 41 causes friction between the fibers contained in the first screening material MC and the fibers, so the first screening material MC is charged. If the first screening material MC aggregates due to the static electricity, it will not easily pass through the opening 41a. On the other hand, while the cylindrical portion 41 is stopped, the charge of the charged first screen MC is discharged, so that the aggregation of the fibers contained in the first screen MC is released. Therefore, when the cylindrical portion 41 starts to rotate from a stopped state, that is, when it is started, the first screening substance MC is in a state where it easily passes through the opening 41a. In this state, the amount of the first screen MC passing through the opening 41a temporarily increases.
又，通過開口41a之第1篩選物MC之量會受到筒部41內之濕度之影響。此處，濕度可稱為相對濕度(RH)。若筒部41內之濕度較高，則第1篩
選物MC所含之纖維之帶電獲得緩和，故可抑制纖維之凝集，因此纖維凝集被解開之量較少。因此，筒部41內之濕度愈高，則通過開口41a之第1篩選物MC之量之變動愈少。又，若筒部41內之濕度較低，則第1篩選物MC所含之纖維之帶電不易緩和，而易大幅產生纖維之凝集，故纖維之凝集被解開之量較大。因此，筒部41內之濕度愈低，通過開口41a之第1篩選物MC量之變動愈大。
In addition, the amount of the first screening substance MC passing through the opening 41a is affected by the humidity in the cylindrical portion 41. Here, the humidity may be referred to as relative humidity (RH). If the humidity in the barrel 41 is high, the first sieve
The electrification of the fibers contained in the selection material MC is alleviated, so that the aggregation of the fibers can be suppressed, so the amount of the fiber aggregation to be unwound is small. Therefore, the higher the humidity in the cylindrical portion 41, the less the change in the amount of the first screen MC passing through the opening 41a. In addition, if the humidity in the cylindrical portion 41 is low, the electrification of the fibers contained in the first screening material MC is not easy to relax, and the aggregation of the fibers is likely to occur greatly, so the amount of the aggregation of the fibers is unwound is large. Therefore, the lower the humidity in the cylindrical portion 41, the greater the variation in the amount of the first screen MC passing through the opening 41a.
又，通過開口41a之第1篩選物MC之量會因第1篩選物MC所含之纖維長度而變動。較短的纖維易通過開口41a。因此，第1篩選物MC所含之纖維愈短，通過開口41a之第1篩選物MC之量愈多。
In addition, the amount of the first screen MC passing through the opening 41a varies depending on the fiber length contained in the first screen MC. Shorter fibers easily pass through the opening 41a. Therefore, the shorter the fibers contained in the first screen MC, the greater the amount of the first screen MC passing through the opening 41a.
即，決定自筒部41供給於網帶46之第1篩選物MC之量之最大要素為筒部41之速度VB。又，作為使第1篩選物MC之量變動之要素，舉出筒部41是否為啟動時、筒部41內之濕度、及第1篩選物MC所含纖維之長度。
That is, the maximum factor that determines the amount of the first screening substance MC supplied from the cylindrical portion 41 to the mesh belt 46 is the speed VB of the cylindrical portion 41. In addition, as an element that changes the amount of the first screen MC, whether the tube portion 41 is at startup, the humidity in the tube portion 41, and the length of the fiber contained in the first screen MC are cited.
若第1網片W1之厚度變動，會導致供給至第1網片形成部45之後續步驟之材料之量之變動，而影響到片材製造裝置100製造之片材S之品質。
If the thickness of the first mesh W1 changes, the amount of material supplied to the subsequent step of the first mesh forming portion 45 will change, which will affect the quality of the sheet S manufactured by the sheet manufacturing apparatus 100.
因此，片材製造裝置100藉由控制部150執行用以抑制第1網片W1之厚度變動之控制。
Therefore, the sheet manufacturing apparatus 100 performs the control for suppressing the thickness variation of the first mesh W1 by the control unit 150.
為進行第1網片W1之厚度相關之控制，片材製造裝置100具備檢測速度VA之第1帶速度檢測部322(圖4)，及檢測速度VB之第1篩速度檢測部321(圖4)。
In order to control the thickness of the first mesh W1, the sheet manufacturing apparatus 100 includes a first belt speed detection unit 322 (FIG. 4) that detects the speed VA, and a first sieve speed detection unit 321 (FIG. 4) that detects the speed VB ).
又，片材製造裝置100可檢測筒部41內之濕度。本實施形態中，作為一例，具備第1溫濕度檢測部323(濕度檢測部)。第1溫濕度檢測部323可作為具備溫度感測器及濕度感測器之感測器單元而構成。溫度感測器例如可使用熱敏電阻、測溫電阻體、熱電耦、IC溫度感測器等元件。濕度感測器只要可檢測相對濕度即可，可使用電阻式濕度感測器或靜電電容式濕度感測器。第1溫濕度感測部323檢測筒部41之內部空間中之溫度及相對濕度。第1溫濕度檢測部323可輸出類比信號作為溫度或濕度之檢測值，亦可輸出表示檢測值之數位資料。又，亦可輸出綜合溫度之檢測值與濕度之檢測值之資料。
In addition, the sheet manufacturing apparatus 100 can detect the humidity in the cylindrical portion 41. In this embodiment, as an example, a first temperature and humidity detection unit 323 (humidity detection unit) is provided.

控制部150進行第1篩馬達40a之動作相關之設定處理(步驟ST1)。步驟ST1之設定處理係進行啟動第1篩馬達40a時之第1篩馬達40a之速度相關之設定之處理。對於設定處理，參照圖7於下文敘述。
The control unit 150 performs setting processing related to the operation of the first sieve motor 40a (step ST1). The setting process in step ST1 is a process for setting the speed of the first screen motor 40a when the first screen motor 40a is started. The setting process will be described below with reference to FIG. 7.
控制部150於設定處理之後，開始啟動順序(步驟ST2)。啟動順序係指片材製造裝置100自停止狀態使片材製造裝置100之各部依序啟動之一連串動作。具體而言，自粗碎部12、解纖部20、篩選部40、第1網片形成部45、旋轉體49、混合部50、堆積部60、第2網片形成部70、成形部80及切斷部90停止之狀態，使該等各部啟動。

FIG. 7 is a flowchart showing the setting process of step ST1 of FIG. 6 in detail.
控制部150判定筒部41之內部是否有解纖物MB(步驟ST21)。解纖物MB之有無例如亦可基於觸控感測器117之輸入而判定。
The control unit 150 determines whether or not there is a defibrated material MB inside the tube 41 (step ST21). The presence or absence of the defibrating object MB can also be determined based on the input of the touch sensor 117, for example.

When it is determined that there is no defibrillator MB in the barrel 41 (step ST21; NO), the control unit 150 sets the first speed condition as a condition for accelerating the speed of the first sieve motor 40a (step ST22), and ends the setting process.
判定筒部41之內部有解纖物MB之情形時(步驟ST21；是)，控制部
150判定藉由第1溫濕度檢測部323檢測出之濕度是否為基準值資料162所含之基準值以上(步驟ST23)。濕度為基準值以上之情形時(步驟ST23；是)，控制部150判定解纖物MB所含纖維之長度是否為基準值資料162所含之基準值以上(步驟ST24)。
When it is determined that there is a defibrillator MB inside the barrel 41 (step ST21; YES), the control unit
150 It is determined whether the humidity detected by the first temperature and humidity detection unit 323 is greater than or equal to the reference value included in the reference value data 162 (step ST23). When the humidity is greater than or equal to the reference value (step ST23; YES), the control unit 150 determines whether the length of the fiber contained in the defibrated material MB is greater than or equal to the reference value contained in the reference value data 162 (step ST24).
纖維之長度為基準值以上之情形時(步驟ST24；是)，控制部150設定第2速度條件作為將第1篩馬達40a之速度加速之條件(步驟ST25)，結束設定處理。
When the length of the fiber is equal to or greater than the reference value (step ST24; YES), the control unit 150 sets the second speed condition as a condition for accelerating the speed of the first screen motor 40a (step ST25), and ends the setting process.
再者，纖維之長度短於基準值之情形時(步驟ST24；否)，控制部150設定第3速度條件作為將第1篩馬達40a之速度加速之條件(步驟ST26)，結束設定處理。
In addition, when the length of the fiber is shorter than the reference value (step ST24; NO), the control unit 150 sets the third speed condition as a condition for accelerating the speed of the first sieve motor 40a (step ST26), and ends the setting process.
另一方面，濕度低於基準值之情形時(步驟ST23；否)，控制部150判定解纖物MB所含纖維之長度是否為基準值資料162所含之基準值以上(步驟ST27)。
On the other hand, when the humidity is lower than the reference value (step ST23; NO), the control unit 150 determines whether the length of the fiber contained in the defibrated material MB is greater than or equal to the reference value contained in the reference value data 162 (step ST27).
纖維之長度為基準值以上之情形時(步驟ST27；是)，控制部150設定第4速度條件作為將第1篩馬達40a之速度加速之條件(步驟ST28)，結束設定處理。
When the length of the fiber is equal to or greater than the reference value (step ST27; YES), the control unit 150 sets the fourth speed condition as a condition for accelerating the speed of the first sieve motor 40a (step ST28), and ends the setting process.
又，纖維之長度短於基準值之情形時(步驟ST27；否)，控制部150設定第5速度條件作為將第1篩馬達40a之速度加速之條件(步驟ST28)，結束設定處理。
When the length of the fiber is shorter than the reference value (step ST27; NO), the control unit 150 sets the fifth speed condition as a condition for accelerating the speed of the first sieve motor 40a (step ST28), and ends the setting process.
第1~第5速度條件為筒部41啟動時將速度VB自零加速之情形之基本條件，包含第1篩馬達40a之目標速度、及達到目標速度為止之時間或第1篩馬達40a之加速度。
The first to fifth speed conditions are the basic conditions for the case where the speed VB is accelerated from zero when the barrel 41 starts, including the target speed of the first screen motor 40a, the time until the target speed is reached, or the acceleration of the first screen motor 40a .
圖8係顯示筒部41之動作速度VB及第1網片W1之厚度之變化例之圖表。速度VB係第1篩速度檢測部321之檢測值，第1網片W1之厚度係第1厚度檢測部324之檢測值。
FIG. 8 is a graph showing an example of changes in the operating speed VB of the cylindrical portion 41 and the thickness of the first mesh W1. The speed VB is the detection value of the first screen speed detection section 321, and the thickness of the first mesh W1 is the detection value of the first thickness detection section 324.
圖8(1)顯示速度VB，(2)顯示第1網片W1之厚度。即，(2)顯示速度VB如(1)般變化之情形之第1厚度檢測部324之檢測值。縱軸為速度VB，及第1網片W1之厚度，縱軸之座標0表示速度0(停止狀態)，及第1網片W1之厚度0。圖8之橫軸為時間之經過，座標0相當於啟動順序之開始時點。啟動順序開始後，將第1篩馬達40a開始旋轉之時刻設為時刻T1。
FIG. 8 (1) shows the speed VB, and (2) shows the thickness of the first mesh W1. That is, (2) the detection value of the first thickness detection section 324 when the display speed VB changes as (1). The vertical axis is the speed VB and the thickness of the first mesh W1. The coordinate 0 on the vertical axis indicates the speed 0 (stopped state) and the thickness 0 of the first mesh W1. The horizontal axis of Fig. 8 is the passage of time, and the coordinate 0 corresponds to the start point of the start sequence. After the start sequence is started, the time at which the first sieve motor 40a starts to rotate is set to time T1.
又，將對第1網片W1之厚度設定之目標值設定為厚度TH1。該動作例中，第1網片W1之厚度保持在厚度TH1較為理想。厚度TH1例如可設為含在2mm~10mm之範圍內之值，但可為更厚，亦可更薄。
In addition, the target value set for the thickness of the first mesh W1 is set as the thickness TH1. In this operation example, the thickness of the first mesh W1 is preferably kept at the thickness TH1. The thickness TH1 can be set to a value included in the range of 2 mm to 10 mm, for example, but it may be thicker or thinner.
圖8係控制部150按照第1速度條件控制第1篩馬達40a之例，將第1厚度檢測部324檢測出之值顯示於(2)。
8 shows an example in which the control unit 150 controls the first sieve motor 40a according to the first speed condition, and displays the value detected by the first thickness detection unit 324 in (2).
圖8及後述之圖9~圖12之例中，將速度VB之目標速度設定為速度V1。目標速度V1相當於本發明之第1速度。目標速度V1例如可設為含在50rpm~1000rpm之範圍內之值，但可為更低速，亦可為更高速。
In the example of FIG. 8 and FIGS. 9 to 12 described later, the target speed of the speed VB is set to the speed V1. The target speed V1 corresponds to the first speed of the present invention. The target speed V1 may be set to a value included in the range of 50 rpm to 1000 rpm, for example, but may be lower speed or higher speed.
又，以下之說明中，將用以將速度VB加速至目標速度V1所需要之時
間稱為加速時間。
In the following description, it will be used to accelerate the speed VB to the target speed V1
The time is called acceleration time.
第1速度條件係於時刻T2速度VB達到目標速度V1之條件。換言之，加速時間係時刻T1至時刻T2之期間TE1。期間TE1例如可設為含在1秒~10秒之範圍內之值，但可為更短時間，亦可為更長時間。
The first speed condition is that the speed VB reaches the target speed V1 at time T2. In other words, the acceleration time is the period TE1 from time T1 to time T2. The period TE1 may be, for example, a value included in the range of 1 second to 10 seconds, but it may be shorter or longer.
如上述，若於筒部41之內部存在解纖物MB之狀態下啟動筒部41，則自筒部41下降之第1篩選物MC之量會暫時多於筒部41中不存在解纖物MB之情形。因此，第1篩馬達40a開始旋轉後下降至網帶46之第1篩選物MC之量會暫時多於適於製造片材S之量。其結果，如圖8(2)所示，導致第1網片W1之厚度超出厚度TH1，厚度之峰值TH2大幅大於厚度TH1。
As described above, if the barrel 41 is activated with the defibrillator MB present inside the barrel 41, the amount of the first screening substance MC descending from the barrel 41 will temporarily be greater than the absence of the defibrillator in the barrel 41 MB situation. Therefore, after the first screen motor 40a starts rotating, the amount of the first screen MC that is lowered to the mesh belt 46 is temporarily larger than the amount suitable for manufacturing the sheet S. As a result, as shown in FIG. 8(2), the thickness of the first mesh W1 exceeds the thickness TH1, and the peak thickness TH2 is significantly larger than the thickness TH1.
圖7之設定處理中，於解纖物MB存在於筒部41之情形時，控制部150設定第2~第5速度條件中之任一者。第2~第5速度條件之任一者皆為將速度VB設為於特定時間低於目標速度V1。具體而言，將加速時間設為較期間TE1更長。
In the setting process of FIG. 7, when the defibrated object MB is present in the cylinder 41, the control unit 150 sets any one of the second to fifth speed conditions. Any one of the second to fifth speed conditions is to set the speed VB to be lower than the target speed V1 at a specific time. Specifically, the acceleration time is set to be longer than the period TE1.
第2速度條件係於筒部41中存在解纖物MB、第1溫濕度檢測部323檢測出之濕度為基準值以上、且纖維長度為基準值以上之情形時設定。第2速度條件係以加速時間長於期間TE1之方式調整之條件。因此，在第2速度條件下速度VB達到目標速度V1之時刻較時刻T2更晚。
The second speed condition is set when the defibrated material MB is present in the cylindrical portion 41, the humidity detected by the first temperature and humidity detection portion 323 is equal to or greater than the reference value, and the fiber length is equal to or greater than the reference value. The second speed condition is a condition adjusted so that the acceleration time is longer than the period TE1. Therefore, the time when the speed VB reaches the target speed V1 under the second speed condition is later than the time T2.
第4速度條件係於筒部41中存在解纖物MB、第1溫濕度檢測部323檢
測出之濕度為低於基準值之低濕度、且纖維長度為基準值以上之情形時設定。該情形時，與設定第2速度條件之情形相比，筒部41內之濕度較低，故自筒部41下降之第1篩選物MC之量暫時變得更多。因此，第4速度條件係將加速時間調整為較第2速度條件更長之條件。在第4速度條件下速度VB達到目標速度V1之時刻較第2速度條件下之時刻更晚。
The fourth speed condition is the presence of the defibrated material MB in the cylinder 41 and the detection by the first temperature and humidity detector 323
Set when the measured humidity is low humidity below the reference value and the fiber length is above the reference value. In this case, the humidity in the cylinder part 41 is lower than that in the case where the second speed condition is set, so the amount of the first screening substance MC descending from the cylinder part 41 temporarily becomes larger. Therefore, the fourth speed condition is to adjust the acceleration time longer than the second speed condition. The time when the speed VB reaches the target speed V1 under the fourth speed condition is later than the time under the second speed condition.
第3速度條件係於筒部41中存在解纖物MB、第1溫濕度檢測部323檢測出之濕度為基準值以上、且纖維長度短於基準值之情形時設定。該情形時，與設定第2速度條件之情形相比，纖維長度較短，故自筒部41下降之第1篩選物MC之量暫時變得較多。因此，第3速度條件係將加速時間調整為較第2速度條件更長之條件。在第3速度條件下速度VB達到目標速度V1之時刻較第2速度條件下之時刻更晚。
The third speed condition is set when the defibrated material MB is present in the cylindrical portion 41, the humidity detected by the first temperature and humidity detection portion 323 is equal to or greater than the reference value, and the fiber length is shorter than the reference value. In this case, the fiber length is shorter than in the case where the second speed condition is set, so the amount of the first screening substance MC descending from the cylindrical portion 41 temporarily becomes large. Therefore, the third speed condition is to adjust the acceleration time to be longer than the second speed condition. The time when the speed VB reaches the target speed V1 under the third speed condition is later than the time under the second speed condition.
又，將第3速度條件與第4速度條件進行比較之情形時，速度VB達到目標速度V1所需要之時間可相同，亦可不同。
In addition, when comparing the third speed condition with the fourth speed condition, the time required for the speed VB to reach the target speed V1 may be the same or different.
加速時間之長短係考量筒部41內之濕度對第1篩選物MC之下降量賦予之影響，及解纖物MB之纖維長度對第1篩選物MC之下降量賦予之影響之何者較大而決定。
The length of the acceleration time considers the effect of the humidity in the cylinder 41 on the drop of the first screen MC, and the effect of the fiber length of the defibrating material MB on the drop of the first screen MC is greater. Decide.
若筒部41內之濕度對第1篩選物MC之下降量賦予之影響大於解纖物MB之纖維長度者，較佳為將第4速度條件之加速時間調整為較第3速度條件之加速時間更長。又，若筒部41內之濕度對第1篩選物MC之下降量賦予之影響小於解纖物MB之纖維長度者，較佳為將第3速度條件之加速時間
調整為較第4速度條件之加速時間更長。
If the influence of the humidity in the cylinder 41 on the decrease of the first screening material MC is greater than the fiber length of the defibrating material MB, it is preferable to adjust the acceleration time of the fourth speed condition to the acceleration time of the third speed condition Longer. In addition, if the influence of the humidity in the cylindrical portion 41 on the decrease of the first screening material MC is less than the fiber length of the defibrating material MB, it is preferable to increase the acceleration time under the third speed condition
Adjust the acceleration time to be longer than the fourth speed condition.
第5速度條件係於筒部41中存在解纖物MB、第1溫濕度檢測部323檢測出之濕度較基準值更低濕度、且纖維長度短於基準值之情形時設定。第5速度條件之加速時間較第1~第4速度條件全數更長。在第5速度條件下速度VB達到目標速度V1之時刻較第1~第4速度條件之任一者更晚。
The fifth speed condition is set when the defibrated material MB is present in the cylindrical portion 41, the humidity detected by the first temperature and humidity detection portion 323 is lower than the reference value, and the fiber length is shorter than the reference value. The acceleration time of the fifth speed condition is longer than that of the first to fourth speed conditions. The speed VB reaches the target speed V1 under the fifth speed condition later than any of the first to fourth speed conditions.
如此，控制部150於自筒部41下降至網帶46之第1篩選物MC之量暫時變多之情形時，藉由使第1篩馬達40a啟動時使速度上昇之態樣變化，而抑制第1網片W1之厚度變動。再者，對應於第1溫濕度檢測部323檢測之濕度或所要解纖之材料之纖維長度，於筒部41啟動時(換言之，第1篩馬達40a啟動時)，使將筒部41之速度上昇之態樣變化，藉此可進而抑制第1網片W1之厚度變動。藉此，片材製造裝置100於製造片材S之步驟中，可使供給至第1網片形成部45之後續步驟之第1篩選物MC之量穩定，可抑制片材S之品質變動。因此，可減輕用以抑制片材S之品質變動之人為的調整作業之負擔。
In this manner, when the amount of the first screening substance MC that has descended from the cylindrical section 41 to the mesh belt 46 temporarily increases, the control section 150 suppresses this by changing the speed increase when the first screening motor 40a is started. The thickness of the first mesh W1 varies. In addition, according to the humidity detected by the first temperature and humidity detection section 323 or the fiber length of the material to be defibrated, when the barrel section 41 is started (in other words, when the first screen motor 40a is started), the speed of the barrel section 41 is adjusted. The change in the rising state can further suppress the thickness variation of the first mesh W1. Thereby, in the step of manufacturing the sheet S, the sheet manufacturing apparatus 100 can stabilize the amount of the first screening material MC in the subsequent step supplied to the first mesh forming section 45, and can suppress the quality variation of the sheet S. Therefore, the burden of manual adjustment work for suppressing the quality variation of the sheet S can be reduced.
圖9、圖10、圖11及圖12係顯示筒部41之動作速度VB及第1網片W1之厚度變化之例之圖表，且係顯示設定第2~第5速度條件之情形之例。該等圖中，(1)係顯示藉由第1篩速度檢測部321檢測之速度VB，(2)係顯示藉由第1厚度檢測部324檢測之第1網片W1之厚度。該等各圖之縱軸、橫軸、目標速度V1、厚度TH1、TH2、時刻T1與圖8共通。又，該等各圖中，為進行比較而圖示圖8所示之時刻T2。
9, 10, 11, and 12 are graphs showing examples of changes in the operating speed VB of the cylinder 41 and the thickness of the first mesh W1, and examples showing the setting of the second to fifth speed conditions. In these figures, (1) shows the speed VB detected by the first screen speed detection section 321, and (2) shows the thickness of the first mesh W1 detected by the first thickness detection section 324. The vertical axis, the horizontal axis, the target speed V1, the thicknesses TH1, TH2, and the time T1 in these drawings are common to FIG. 8. In addition, in these figures, the time T2 shown in FIG. 8 is illustrated for comparison.
圖9係使速度VB階段性變化之例，尤其係顯示使速度VB兩階段變化之例。控制部150於將速度VB加速至目標速度V1之前，設置以較目標速度V1為低速之中間速度V2維持之期間。具體而言，控制部150以於時刻T1開始第1篩馬達40a之旋轉、於時刻T3速度VB達到中間速度V2之方式進行加速。控制部150以如下方式進行控制：將速度VB維持在中間速度V2直到時刻T4，使第1篩馬達40a自時刻T4起進而增速，於時刻T5達到目標速度V1。
FIG. 9 shows an example of changing the speed VB in stages, and particularly shows an example of changing the speed VB in two stages. Before accelerating the speed VB to the target speed V1, the control unit 150 sets a period during which the intermediate speed V2 is maintained at a lower speed than the target speed V1. Specifically, the control unit 150 accelerates so that the rotation of the first sieve motor 40a starts at time T1, and the speed VB reaches the intermediate speed V2 at time T3. The control unit 150 controls such that the speed VB is maintained at the intermediate speed V2 until time T4, the first screen motor 40a is further increased from time T4, and reaches the target speed V1 at time T5.
圖9之例中，速度VB達到目標速度V1之時刻T5較上述時刻T2更晚。即，控制部150開始第1篩馬達40a之旋轉後，於時刻T1~T5期間，維持速度VB低於目標速度V1之狀態(速度V2)。如圖9(2)所示，第1厚度檢測部324之檢測值自時刻T2附近變動，但第1網片W1之厚度之峰值TH3小於圖8所示厚度之峰值TH2。因此，可知第1網片W1之厚度變動受到抑制。
In the example of FIG. 9, the time T5 at which the speed VB reaches the target speed V1 is later than the time T2 described above. That is, after the control unit 150 starts the rotation of the first sieve motor 40a, it maintains the state where the speed VB is lower than the target speed V1 (speed V2) from time T1 to T5. As shown in FIG. 9(2), the detection value of the first thickness detection unit 324 varies from around time T2, but the peak value TH3 of the thickness of the first mesh W1 is smaller than the peak value TH2 of the thickness shown in FIG. Therefore, it can be seen that the thickness variation of the first mesh W1 is suppressed.
圖10係使速度VB階段性變化之例，尤其係顯示使速度VB三階段變化之例。控制部150於將速度VB加速至目標速度V1之前，設置以較目標速度V1為低速之中間速度V4及中間速度V5維持之期間。具體而言，控制部150以於時刻T1開始第1篩馬達40a之旋轉、於時刻T11速度VB達到中間速度V4之方式進行加速。控制部150以如下方式進行控制：將速度VB維持在中間速度V4直到時刻T12，使第1篩馬達40a自時刻T12起進而增速，於時刻T13達到目標速度V5。控制部150以如下方式進行控制：將速度VB維持在中間速度V5直到時刻T14，使第1篩馬達40a自時刻T14起進而增
速，於時刻T15達到目標速度V1。
FIG. 10 shows an example of changing the speed VB in stages, and particularly shows an example of changing the speed VB in three stages. The control unit 150 sets a period during which the intermediate speed V4 and the intermediate speed V5 are maintained at a lower speed than the target speed V1 before accelerating the speed VB to the target speed V1. Specifically, the control unit 150 accelerates so that the rotation of the first sieve motor 40a starts at time T1, and the speed VB reaches the intermediate speed V4 at time T11. The control unit 150 controls such that the speed VB is maintained at the intermediate speed V4 until time T12, the first screen motor 40a is further increased from time T12, and reaches the target speed V5 at time T13. The control unit 150 controls such that the speed VB is maintained at the intermediate speed V5 until time T14, and the first screen motor 40a is further increased from time T14.
Speed, reaching the target speed V1 at time T15.
圖10之例中，速度VB達到目標速度V1之時刻T15較上述時刻T2更晚。即，控制部150開始第1篩馬達40a之旋轉後，於時刻T1~T5期間，維持速度VB低於目標速度V1之狀態。
In the example of FIG. 10, the time T15 at which the speed VB reaches the target speed V1 is later than the time T2 described above. That is, after the control unit 150 starts the rotation of the first sieve motor 40a, it maintains the state where the speed VB is lower than the target speed V1 during the time period T1 to T5.
如圖10(2)所示，第1厚度檢測部324之檢測值自時刻T11附近變動，但第1網片W1之厚度之峰值TH4小於圖8所示厚度之峰值TH2。尤其，於第1篩選物MC之下降量易增大之筒部41開始旋轉後，立即設置以較目標速度V1更大幅低速之中間速度V4旋轉之期間(時刻T1~T12)，藉此將厚度之峰值TH4成功抑制為較低。
As shown in FIG. 10(2), the detection value of the first thickness detection unit 324 varies from around time T11, but the peak value TH4 of the thickness of the first mesh W1 is smaller than the peak value TH2 of the thickness shown in FIG. In particular, immediately after the rotation of the cylindrical portion 41 where the fall amount of the first screening substance MC tends to increase, a period of time (time T1 to T12) at an intermediate speed V4 that is significantly lower than the target speed V1 is set, thereby reducing the thickness The peak TH4 was successfully suppressed to a low level.
如圖9及圖10所示之例，控制部150可使速度VB階段性變化，速度VB之階段數或中間速度可任意變更。例如，亦可使速度VB以四階段以上變化。
As shown in the examples shown in FIGS. 9 and 10, the control unit 150 can change the speed VB in stages, and the number of steps or the intermediate speed of the speed VB can be arbitrarily changed. For example, the speed VB may be changed in four stages or more.
圖11係顯示使速度VB線性變化之例。控制部150將速度VB自速度0線形加速至目標速度V1，使速度VB達到目標速度V1之時刻T21遲於時刻T2。即，加速時間係較期間TE1(圖8)更長之例。如圖11(2)所示，第1網片W1之厚度之峰值TH5小於圖8所示之厚度之峰值TH2，成功抑制第1網片W1之厚度變動。
Fig. 11 shows an example of linearly changing the speed VB. The control unit 150 linearly accelerates the speed VB from the speed 0 to the target speed V1, so that the time T21 at which the speed VB reaches the target speed V1 is later than the time T2. That is, the acceleration time is longer than the period TE1 (FIG. 8). As shown in FIG. 11(2), the peak TH5 of the thickness of the first mesh W1 is smaller than the peak TH2 of the thickness shown in FIG. 8, which successfully suppresses the thickness variation of the first mesh W1.
圖11之例中，控制部150之第1篩馬達40a之控制較為簡單。因此，有容易管理用以控制第1篩馬達40a之各種資料、條件之設定及調整較為簡單
等優點。
In the example of FIG. 11, the control of the first screen motor 40a of the control unit 150 is relatively simple. Therefore, it is easy to manage the setting and adjustment of various data and conditions for controlling the first screen motor 40a
Etc.
圖12係顯示使速度VB非線形變化之例。控制部150係以於速度VB自速度0加速至目標速度V1之期間使加速度變化、於時刻T31速度VB達到目標速度V1之方式控制第1篩馬達40a。
Fig. 12 shows an example of changing the velocity VB non-linearly. The control unit 150 controls the first sieve motor 40a so that the acceleration changes while the speed VB accelerates from the speed 0 to the target speed V1, and the speed VB reaches the target speed V1 at time T31.
詳細而言，包含：於時刻T1開始旋轉後立即減小加速度，其後隨著時間經過使加速度增大的第1動作，及進而隨著速度VB接近目標速度V1而使加速度減少的第2動作。
In detail, it includes: the first action to decrease the acceleration immediately after the rotation starts at time T1, and then the first action to increase the acceleration as time passes, and the second action to decrease the acceleration as the speed VB approaches the target speed V1 .
圖12之例中，由於速度VB達到目標速度V1之時刻T31遲於時刻T2，故加速時間長於期間TE1(圖8)。又，由於速度VB之變化率即加速度之變動較和緩，故抑制施加於筒部41內部之解纖物MB之力的變動。因此，可期待抑制自筒部41下降之第1篩選物MC量之變動之效果。如圖12(2)所示，第1網片W1之厚度之峰值TH6小於圖8所示之厚度之峰值TH2，成功抑制第1網片W1之厚度變動。
In the example of FIG. 12, since the time T31 at which the speed VB reaches the target speed V1 is later than the time T2, the acceleration time is longer than the period TE1 (FIG. 8). In addition, since the change rate of the speed VB, that is, the change in acceleration is relatively gentle, the change in the force applied to the defibrating material MB inside the cylinder 41 is suppressed. Therefore, the effect of suppressing the change in the amount of the first screening substance MC that has fallen from the cylindrical portion 41 can be expected. As shown in FIG. 12(2), the peak TH6 of the thickness of the first mesh W1 is smaller than the peak TH2 of the thickness shown in FIG. 8, which successfully suppresses the thickness variation of the first mesh W1.
第2~第5速度條件可採用圖9~圖12所示之各例。例如，第2~第5速度條件全數皆可應用圖9所示之2階段之加速模態。該情形時，第2~第5速度條件係以速度VB達到目標速度V1之時刻T5為不同時刻之方式設定。又，第2~第5速度條件亦可如圖9所示，包含使速度VB變化之各種參數。
For the second to fifth speed conditions, the examples shown in FIGS. 9 to 12 can be used. For example, the 2nd to 5th speed conditions can be applied to the acceleration mode of 2 stages shown in FIG. 9. In this case, the second to fifth speed conditions are set such that the time T5 at which the speed VB reaches the target speed V1 is a different time. In addition, the second to fifth speed conditions may include various parameters that change the speed VB as shown in FIG. 9.
又，第2~第5速度條件下之速度VB之變化態樣亦可非共通。例如，第2~第5速度條件亦可為以圖9~圖12所示態樣中不同之態樣使速度VB變
化之條件。
In addition, the change of the speed VB under the second to fifth speed conditions may not be common. For example, the second to fifth speed conditions may also be different from the patterns shown in Figures 9 to 12 to change the speed VB
Conditions.
又，圖9~圖12所示之例中，速度VB達到目標速度V1後維持固定，但於片材S之製造中，速度VB之目標速度V1亦可不固定。例如，亦可對應於片材S之製造條件或片材製造裝置100之動作狀態，使速度VB變化。
In addition, in the examples shown in FIGS. 9 to 12, the speed VB remains constant after reaching the target speed V1, but in the manufacture of the sheet S, the target speed V1 of the speed VB may not be fixed. For example, the speed VB may be changed according to the manufacturing conditions of the sheet S or the operating state of the sheet manufacturing apparatus 100.
又，作為對應於所檢測之濕度之控制，亦可基於解纖處理部101停止時檢測之濕度、及解纖處理部101重新起動後檢測之濕度之結果，進行決定較目標速度V1更低速之中間速度V2之控制。
In addition, as control corresponding to the detected humidity, it is also possible to determine the speed lower than the target speed V1 based on the humidity detected when the defibration processing unit 101 is stopped and the humidity detected after the defibration processing unit 101 is restarted. Control of intermediate speed V2.
如上說明，應用本發明之第1實施形態之片材製造裝置100具備筒部41，其篩選含有纖維之材料即第1篩選物MC；及網帶46，其使自筒部41排出之第1篩選物MC堆積。片材製造裝置100具備作為對堆積於網帶46之第1篩選物MC進行加工之加工部之製造部102之各部。製造片材S之動作中、即加工執行中，筒部41以目標速度V1動作，筒部41自停止狀態啟動之情形時，於筒部41啟動後，執行包含筒部41以較目標速度V1更低速進行動作之狀態之啟動動作。此處，加工部可為第1網片形成部45之後續步驟之任一者，例如，自構成製造部102之各部任意選擇。
As described above, the sheet manufacturing apparatus 100 to which the first embodiment of the present invention is applied includes the cylindrical portion 41 that screens the first screening material MC that is a fiber-containing material; and the mesh belt 46 that makes the first discharged from the cylindrical portion 41 Screen MC is stacked. The sheet manufacturing apparatus 100 includes each unit of the manufacturing unit 102 as a processing unit that processes the first screening material MC deposited on the mesh belt 46. During the operation of manufacturing the sheet S, that is, during the execution of processing, the cylinder 41 operates at the target speed V1, and when the cylinder 41 is started from the stop state, after the cylinder 41 is started, the operation including the cylinder 41 at the target speed V1 is performed. The starting action in the state where the action is performed at a lower speed. Here, the processing portion may be any one of the subsequent steps of the first mesh forming portion 45, for example, it may be arbitrarily selected from each portion constituting the manufacturing portion 102.
根據本發明之纖維處理裝置及應用纖維處理裝置之控制方法之第1實施形態之片材製造裝置100，於自筒部41移動至網帶46之第1篩選物MC之量易變動之啟動時，適當調整筒部41之動作速度。藉此，可抑制第1篩選物MC量之變動。因此，可抑制第1網片W1之厚度變動，故於片材製造裝置100製造片材S之步驟中，可使供給至第1網片形成部45之後續步驟之第1篩選物MC之量穩定化。例如，可抑制片材S之品質變動，可減輕用以使
片材S之品質穩定化之人為的調整作業之負擔。
The sheet manufacturing apparatus 100 according to the first embodiment of the fiber processing apparatus and the control method using the fiber processing apparatus of the present invention is activated when the amount of the first screening substance MC moving from the cylinder 41 to the mesh belt 46 is easily changed , Adjust the operating speed of the barrel 41 appropriately. This can suppress the change in the MC amount of the first screening substance. Therefore, the thickness variation of the first mesh W1 can be suppressed, so that in the step of manufacturing the sheet S by the sheet manufacturing apparatus 100, the amount of the first screening substance MC in the subsequent step supplied to the first mesh forming portion 45 can be made Stabilization. For example, the quality variation of the sheet S can be suppressed and the
The burden of manual adjustment of the quality of the sheet S is stabilized.
片材製造裝置100於啟動動作中，將筒部41以較第1速度更低速進行動作之狀態維持特定時間。例如，如圖9~圖12所示之例，可將速度VB未達到目標速度V1之狀態，維持較期間TE1(圖8)更長時間。藉此，於自筒部41下降之第1篩選物MC之量易增大之時點，將速度VB維持在較目標速度V1更低速，故可有效抑制第1篩選物MC量之變動。
In the starting operation, the sheet manufacturing apparatus 100 maintains the state in which the cylindrical portion 41 operates at a lower speed than the first speed for a specific time. For example, as in the examples shown in FIGS. 9-12, the state where the speed VB does not reach the target speed V1 can be maintained for a longer period of time than the period TE1 (FIG. 8). As a result, at a time when the amount of the first screen MC falling from the cylinder portion 41 is likely to increase, the speed VB is maintained at a lower speed than the target speed V1, so that the change in the amount of the first screen MC can be effectively suppressed.
又，片材製造裝置100於啟動動作中，以將筒部41之動作速度較目標速度V1更低速之第2速度維持特定時間之方式使筒部41動作。第2速度例如於圖9之例中相當於中間速度V2，於圖10之例中相當於中間速度V4、V5。該情形時，藉由將速度VB維持在低於目標速度V1之一定速度，而可有效抑制自筒部41移動至網帶46之第1篩選物MC量之變動。
In addition, during the start-up operation, the sheet manufacturing apparatus 100 operates the cylinder 41 so that the second speed at which the cylinder 41 operates at a lower speed than the target speed V1 is maintained for a specific time. The second speed corresponds to the intermediate speed V2 in the example of FIG. 9, and corresponds to the intermediate speeds V4 and V5 in the example of FIG. 10. In this case, by maintaining the speed VB at a certain speed lower than the target speed V1, it is possible to effectively suppress the change in the amount of the first screening substance MC that moves from the cylinder 41 to the mesh belt 46.
又，片材製造裝置100於啟動動作中，以將筒部41之動作速度較第1速度更低速之狀態維持特定時間之方式，使筒部41之動作速度變化。例如，如圖11之例，使速度VB線形變化，或如圖12之例，使速度VB非線形變化之情形時，維持速度VB低於目標速度V1之狀態。該情形時，藉由將速度VB維持在低於目標速度V1之一定速度，而可有效抑制自筒部41移動至網帶46之第1篩選物MC量之變動。
In addition, during the start-up operation, the sheet manufacturing apparatus 100 changes the operation speed of the cylinder 41 so that the operation speed of the cylinder 41 is kept at a lower speed than the first speed for a certain period of time. For example, when the speed VB is linearly changed as in the example of FIG. 11, or when the speed VB is non-linearly changed as in the example of FIG. 12, the state where the speed VB is lower than the target speed V1 is maintained. In this case, by maintaining the speed VB at a certain speed lower than the target speed V1, it is possible to effectively suppress the change in the amount of the first screening substance MC that moves from the cylinder 41 to the mesh belt 46.
又，片材製造裝置100中，於筒部41中存在解纖物MB之狀態下，筒部41自停止狀態啟動。該情形時，執行上述啟動動作。藉此，於自筒部
41下降之第1篩選物MC之量易增大之狀態下，控制速度VB，藉此可有效抑制第1篩選物MC量之變動。又，於自筒部41下降之第1篩選物MC之量不易變動之狀態下，執行通常之啟動順序，故可防止片材S之製造效率降低。
In addition, in the sheet manufacturing apparatus 100, when the defibrated material MB is present in the cylindrical portion 41, the cylindrical portion 41 is started from the stopped state. In this case, the above start-up action is performed. By this, in the self-tube part
41. In a state where the amount of the first screening substance MC that has fallen is likely to increase, the speed VB is controlled, thereby effectively suppressing the change in the amount of the first screening substance MC. In addition, in a state where the amount of the first screening material MC descending from the tube portion 41 is not easily changed, the normal start-up sequence is executed, so that the manufacturing efficiency of the sheet S can be prevented from being lowered.
片材製造裝置100具備控制筒部41之動作之控制部150，控制部150於製造片材S之動作中，基於目標速度V1使筒部41動作。控制部150於筒部41啟動後，基於較目標速度V1更低速之設定速度，使筒部41動作特定時間。設定速度例如於圖9之例中相當於中間速度V2，於圖10之例中相當於中間速度V4、V5。該情形時，藉由將速度VB控制為低於目標速度V1之速度，而可有效抑制自筒部41移動至網帶46之第1篩選物MC量之變動。
The sheet manufacturing apparatus 100 includes a control unit 150 that controls the operation of the cylindrical portion 41. During the operation of manufacturing the sheet S, the control unit 150 operates the cylindrical portion 41 based on the target speed V1. The control unit 150 operates the cylinder unit 41 for a specific time based on the set speed lower than the target speed V1 after the cylinder unit 41 is activated. For example, the set speed corresponds to the intermediate speed V2 in the example of FIG. 9, and corresponds to the intermediate speeds V4 and V5 in the example of FIG. 10. In this case, by controlling the speed VB to a speed lower than the target speed V1, it is possible to effectively suppress the change in the amount of the first screening substance MC moving from the cylinder 41 to the mesh belt 46.
又，片材製造裝置100具備檢測濕度之第1溫濕度檢測部323。控制部150對應於第1溫濕度檢測部323所檢測之濕度之資訊，控制設定速度。因此，可適當對應於因濕度變動所致之第1篩選物MC量之變動，可有效抑制第1篩選物MC量之變動。例如，如上述，筒部41內之濕度愈高，通過開口41a之第1篩選物MC量之變動愈少。又，若筒部41內之濕度較低，則不易緩和第1篩選物MC所含之纖維之帶電，易大幅產生纖維之凝集，故纖維凝集被解開之量較大。因此，筒部41內之濕度愈低，通過開口41a之第1篩選物MC量之變動愈大。例如，可由第1溫濕度檢測部323之檢測值檢測或推測筒部41內之濕度之情形時，藉由對應於筒部41內之濕度控制設定速度，可適當應對因濕度影響所致之第1篩選物MC量之變動。
In addition, the sheet manufacturing apparatus 100 includes a first temperature and humidity detection unit 323 that detects humidity. The control unit 150 controls the set speed in accordance with the humidity information detected by the first temperature and humidity detection unit 323. Therefore, it is possible to appropriately respond to the change in the amount of MC of the first screening substance due to the change in humidity, and to effectively suppress the change in the amount of MC of the first screening substance. For example, as described above, the higher the humidity in the cylindrical portion 41, the less the change in the amount of the first screening substance MC passing through the opening 41a. In addition, if the humidity in the cylindrical portion 41 is low, it is not easy to relax the electrification of the fibers contained in the first screening material MC, and it is easy to greatly agglomerate the fibers, so the amount of fiber agglomeration is unwound is large. Therefore, the lower the humidity in the cylindrical portion 41, the greater the variation in the amount of the first screen MC passing through the opening 41a. For example, when the detection value of the first temperature and humidity detection unit 323 detects or estimates the humidity in the barrel 41, by controlling the set speed corresponding to the humidity in the barrel 41, the first 1 Changes in the MC amount of the screening substance.
又，筒部41構成為圓筒形狀，於筒部41之周面設有開口，且以圓筒之軸為中心而旋轉。因此，若於筒部41之內部存在解纖物MB之狀態下啟動筒部41，則於啟動時下降至網帶46之第1篩選物MC之量易變動。該構成中，藉由控制部150之控制，確保筒部41以較目標速度V1更低速旋轉之期間，故可抑制第1篩選物MC量之變動。
In addition, the cylindrical portion 41 is configured in a cylindrical shape, an opening is provided on the peripheral surface of the cylindrical portion 41, and rotates around the axis of the cylinder. Therefore, if the cylindrical portion 41 is activated in the state where the defibrated material MB is present inside the cylindrical portion 41, the amount of the first screening substance MC that has dropped to the mesh belt 46 at the time of activation is likely to vary. In this configuration, under the control of the control unit 150, the period during which the cylindrical portion 41 rotates at a lower speed than the target speed V1 is ensured, so that the variation in the amount of the first screening substance MC can be suppressed.
應用本發明之纖維原料再生裝置之片材製造裝置100具備作為將含有纖維之原料MA微細化之微細化部之解纖部20。片材製造裝置100具備：筒部41，其篩選藉由微細化部微細化之解纖物MB；及作為堆積部之網帶46，其使自筒部41排出之第1篩選物MC堆積。片材製造裝置100具備製造部102之各部，作為對堆積於網格46之第1篩選物MC進行加工之加工部。又，片材製造裝置100於片材S之製造中即加工部之加工執行中，使筒部41以目標速度V1動作。片材製造裝置100中，於筒部41中存在解纖物MB之狀態下筒部41自停止狀態啟動之情形時，於筒部41啟動後，執行包含筒部41以較目標速度V1更低速進行動作之狀態之啟動動作。根據該構成，於第1篩選物MC自筒部41移動之量易變動之狀態下，藉由將筒部41之速度設為較目標速度V1更低速，而可抑制第1篩選物MC量之變動。
The sheet manufacturing apparatus 100 to which the fiber material recycling device of the present invention is applied includes a defibrating unit 20 as a miniaturizing unit that miniaturizes a fiber-containing material MA. The sheet manufacturing apparatus 100 includes a cylindrical portion 41 that screens the defibrated material MB fined by the miniaturizing portion, and a mesh belt 46 as a stacking portion that stacks the first screening material MC discharged from the cylindrical portion 41. The sheet manufacturing apparatus 100 includes each section of the manufacturing section 102 as a processing section that processes the first screening substance MC deposited on the grid 46. In addition, the sheet manufacturing apparatus 100 operates the cylindrical portion 41 at the target speed V1 during the manufacture of the sheet S, that is, during the processing of the processing portion. In the sheet manufacturing apparatus 100, when the barrel 41 is started from the stop state in the state where the defibrated material MB is present in the barrel 41, after the barrel 41 is started, the cylinder 41 is included at a lower speed than the target speed V1 The starting action in the state of the action. According to this configuration, in a state where the amount of movement of the first screening material MC from the cylindrical portion 41 is easily changed, by setting the speed of the cylindrical portion 41 to be lower than the target speed V1, the amount of the first screening material MC can be suppressed change.
第1實施形態中，使筒部41之速度VB變化之態樣不限於圖9~圖12所示之例。例如，筒部41啟動後，亦可使速度VB較目標速度V1更高速。具體而言，控制部150亦可為如下態樣：於筒部41啟動之情形時，將速度VB加速至較目標速度V1更高速，於加速完成後之特定時間，維持筒部41以
不同於目標速度V1之速度VB進行動作之狀態。如此，於啟動動作中，亦可執行包含如下動作之動作：第1動作，其使筒部41之加速度隨著時間而增大；及第2動作，其於上述時間經過後，使筒部41之加速度減少。該情形時，藉由將筒部41之速度變化適當控制，而可將第1篩選物MC量之變動減緩。例如，藉由以控制部150控制筒部41之加速度之變化，可抑制因筒部41之加速度變化而施加於筒部41內之解纖物MB之力。該情形時，可期待將第1篩選物MC量之變動減緩之效果。
In the first embodiment, the manner of changing the speed VB of the cylindrical portion 41 is not limited to the examples shown in FIGS. 9 to 12. For example, after the cylinder 41 is activated, the speed VB may be higher than the target speed V1. Specifically, the control unit 150 may be as follows: when the barrel 41 is activated, the speed VB is accelerated to a higher speed than the target speed V1, and the barrel 41 is maintained at a specific time after the acceleration is completed.
The state in which the speed VB different from the target speed V1 operates. In this way, in the start-up operation, an operation including the following operations can also be performed: the first operation, which increases the acceleration of the cylinder 41 with time; and the second operation, which causes the cylinder 41 after the above time has passed The acceleration is reduced. In this case, by appropriately controlling the speed change of the cylinder part 41, the change in the amount of the first screening substance MC can be alleviated. For example, by controlling the change in the acceleration of the cylinder 41 with the control unit 150, the force applied to the defibrating object MB in the cylinder 41 due to the change in the acceleration of the cylinder 41 can be suppressed. In this case, the effect of reducing the change in the MC amount of the first screening substance can be expected.

In the above-described first embodiment, an example in which the speed VB of the cylinder part 41 is adjusted by the drive control unit 152 controlling the first screen motor 40a during the starting operation has been described.
第2實施形態係說明驅動控制部152藉由於啟動動作中控制第2篩馬達60a，而調整筒部61之速度VD之例。第2實施形態中，筒部61相當於篩部，藉由筒部61篩選之混合物MX相當於材料，網帶72相當於堆積部。第2溫濕度檢測部333相當於濕度檢測部。
The second embodiment describes an example in which the drive control unit 152 adjusts the speed VD of the cylinder 61 by controlling the second screen motor 60a during the starting operation. In the second embodiment, the cylindrical portion 61 corresponds to the sieve portion, the mixture MX screened by the cylindrical portion 61 corresponds to the material, and the mesh belt 72 corresponds to the accumulation portion. The second temperature and humidity detection unit 333 corresponds to the humidity detection unit.
[2-1.第2網片之形成條件]
[2-1. Conditions for forming the second mesh sheet]
此處，參照圖3，針對以第2網片形成部70形成之第2網片W2之形成條件進行說明。
Here, with reference to FIG. 3, the formation conditions of the second mesh W2 formed by the second mesh forming portion 70 will be described.
第2網片W2之厚度係根據供給於網帶72之材料即第2混合物MX之量，及網帶72之每單位時間之移動量而決定。網帶72之每單位時間之移動量為速度VC。
The thickness of the second mesh W2 is determined based on the amount of the second mixture MX that is the material supplied to the mesh belt 72 and the amount of movement of the mesh belt 72 per unit time. The movement amount of the mesh belt 72 per unit time is the speed VC.
作為決定供給於網帶72之混合物MX之量、即通過開口61a之混合物MX之量之要素，舉出速度VD。速度VD愈高速，筒部61內之混合物MX愈被快速拆解，故混合物MX易通過開口61a。又，速度VD愈高速，混合物MX愈易通過開口61a。因此，速度VD愈快，通過開口61a之混合物MX之量愈多。
As an element that determines the amount of the mixture MX supplied to the mesh belt 72, that is, the amount of the mixture MX passing through the opening 61a, the speed VD is cited. The higher the speed VD, the more quickly the mixture MX in the barrel 61 is disassembled, so the mixture MX easily passes through the opening 61a. Also, the higher the speed VD, the easier the mixture MX passes through the opening 61a. Therefore, the faster the speed VD, the greater the amount of the mixture MX passing through the opening 61a.
通過開口61a之混合物MX之量會於筒部61自停止狀態啟動時變動。由於在筒部61內，因筒部61之旋轉使得混合物MX所含之纖維與纖維間產生摩擦，故混合物MX帶電。若混合物MX因該靜電而凝集，則不易通過開口61a。另一方面，由於在筒部61停止期間，帶電之混合物MX之電荷放電，故混合物MX所含之纖維之凝集被解開。因此，筒部61自停止狀態開始旋轉時、即啟動時，通過開口61a之混合物MX之量會暫時變多。
The amount of the mixture MX passing through the opening 61a will change when the cylinder 61 starts from the stopped state. Since the rotation of the cylindrical portion 61 causes friction between the fibers contained in the mixture MX and the fibers in the cylindrical portion 61, the mixture MX is charged. If the mixture MX is aggregated due to the static electricity, it will not easily pass through the opening 61a. On the other hand, since the charge of the charged mixture MX is discharged while the cylindrical portion 61 is stopped, the aggregation of the fibers contained in the mixture MX is released. Therefore, the amount of the mixture MX passing through the opening 61a temporarily increases when the cylindrical portion 61 starts to rotate from the stopped state, that is, when it starts.
又，通過開口61a之混合物MX之量會受到筒部61內之濕度之影響。此處，濕度可稱為相對濕度。若筒部61內之濕度較低，則混合物MX帶電，易產生纖維之凝集。因此，筒部61內之濕度愈低，筒部61自停止狀態開始旋轉時、即啟動時，通過開口61a之混合物MX之量愈暫時變多。
In addition, the amount of the mixture MX passing through the opening 61a is affected by the humidity in the cylinder 61. Here, the humidity may be referred to as relative humidity. If the humidity in the cylindrical portion 61 is low, the mixture MX is charged, and fiber aggregation is likely to occur. Therefore, the lower the humidity in the cylinder 61, the more temporarily the amount of the mixture MX passing through the opening 61a is increased when the cylinder 61 starts to rotate from the stopped state, that is, at startup.
又，通過開口61a之混合物MX之量會根據混合物MX所含之纖維長度而變動。短纖維易通過開口61a。因此，混合物MX含有之纖維愈短，通過開口61a之混合物MX之量愈多。
In addition, the amount of the mixture MX passing through the opening 61a varies according to the fiber length contained in the mixture MX. Short fibers easily pass through the opening 61a. Therefore, the shorter the fibers contained in the mixture MX, the greater the amount of the mixture MX passing through the opening 61a.
即，決定自筒部61供給於網帶72之混合物MX之量之最大之要素為筒部61之速度VD。又，作為使混合物MX之量變動之要素，舉出筒部61是否為啟動時、筒部61內之濕度及混合物MX所含纖維之長度。
That is, the factor that determines the maximum amount of the mixture MX supplied from the cylinder 61 to the mesh belt 72 is the speed VD of the cylinder 61. In addition, as an element that changes the amount of the mixture MX, whether the cylinder portion 61 is at startup, the humidity in the cylinder portion 61, and the length of the fiber contained in the mixture MX are cited.
若第2網片W2之厚度變動，則導致供給於第2網片形成部70之後續步驟之材料之量之變動，影響到片材製造裝置100製造之片材S之品質。
If the thickness of the second mesh W2 changes, the amount of material supplied to the subsequent step of the second mesh forming portion 70 changes, which affects the quality of the sheet S manufactured by the sheet manufacturing apparatus 100.
因此，片材製造裝置100藉由控制部150執行用以抑制第2網片W2之厚度變動之控制。
Therefore, the sheet manufacturing apparatus 100 uses the control unit 150 to perform control for suppressing the thickness variation of the second mesh W2.
由於控制裝置110進行第2網片W2之厚度相關之控制，故可取得第2厚度檢測部334之檢測值。又，如圖4所示，控制裝置110可控制第2篩馬達60a及第2帶馬達74b之旋轉速度。
Since the control device 110 controls the thickness of the second mesh W2, the detection value of the second thickness detection unit 334 can be obtained. As shown in FIG. 4, the control device 110 can control the rotation speed of the second screen motor 60a and the second belt motor 74b.
[2-2.片材製造裝置之動作]
[2-2. Operation of sheet manufacturing apparatus]
控制部150藉由驅動控制部152執行圖6所示之動作。在步驟ST1之設定處理中，控制部150進行第2篩馬達60a之動作相關之設定。該情形時，控制部150以圖7之設定處理，設定筒部61之速度VD相關之第1~第5速度條件。第1實施形態中，對筒部41之速度VB設定第1~第5速度條件，但第1~第5速度條件亦可對筒部61之速度VD設定。
The control unit 150 performs the operation shown in FIG. 6 by the drive control unit 152. In the setting process of step ST1, the control unit 150 performs settings related to the operation of the second sieve motor 60a. In this case, the control unit 150 uses the setting process of FIG. 7 to set the first to fifth speed conditions related to the speed VD of the cylinder 61. In the first embodiment, the first to fifth speed conditions are set for the speed VB of the barrel 41, but the first to fifth speed conditions may also be set for the speed VD of the barrel 61.
控制部150對速度VD執行圖7之設定處理。控制部150判定筒部61之內部是否有混合物MX(步驟ST21)。混合物MX之有無例如亦可基於觸控感測器117之輸入而判定。
The control unit 150 executes the setting process of FIG. 7 for the speed VD. The control unit 150 determines whether or not the mixture MX is present inside the cylinder 61 (step ST21). The presence or absence of the mixture MX can also be determined based on the input of the touch sensor 117, for example.
判定筒部61之內部無混合物MX之情形時(步驟ST21；否)，控制部150設定第1速度條件作為將第2篩馬達60a之速度加速之條件(步驟ST22)，結束設定處理。
When it is determined that there is no mixture MX in the cylinder 61 (step ST21; NO), the control unit 150 sets the first speed condition as a condition for accelerating the speed of the second sieve motor 60a (step ST22), and ends the setting process.
判定筒部61之內部有混合物MX之情形時(步驟ST21；是)，控制部150判定藉由第1溫濕度檢測部323檢測出之濕度是否為基準值資料162所含之基準值以上(步驟ST23)。濕度為基準值以上之情形時(步驟ST23；是)，控制部150判定混合物MX所含纖維之長度是否為基準值資料162所含之基準值以上(步驟ST24)。由於混合物MX所含之纖維來自原料MA，故與解纖物MB所含之纖維之長度相同。
When it is determined that there is a mixture MX inside the cylinder 61 (step ST21; YES), the control unit 150 determines whether the humidity detected by the first temperature and humidity detection unit 323 is greater than or equal to the reference value contained in the reference value data 162 (step ST23). When the humidity is greater than or equal to the reference value (step ST23; YES), the control unit 150 determines whether the length of the fiber contained in the mixture MX is greater than or equal to the reference value contained in the reference value data 162 (step ST24). Since the fiber contained in the mixture MX comes from the raw material MA, it has the same length as the fiber contained in the defibrated material MB.
纖維之長度為基準值以上之情形時(步驟ST24；是)，控制部150設定第2速度條件作為將第2篩馬達60a之速度加速之條件(步驟ST25)，結束設定處理。
When the length of the fiber is equal to or greater than the reference value (step ST24; YES), the control unit 150 sets the second speed condition as a condition for accelerating the speed of the second screen motor 60a (step ST25), and ends the setting process.
又，纖維之長度短於基準值之情形時(步驟ST24；否)，控制部150設定第3速度條件作為將第2篩馬達60a之速度加速之條件(步驟ST26)，結束設定處理。
When the length of the fiber is shorter than the reference value (step ST24; NO), the control unit 150 sets the third speed condition as a condition for accelerating the speed of the second screen motor 60a (step ST26), and ends the setting process.
另一方面，濕度低於基準值之情形時(步驟ST23；否)，控制部150判定混合物MX所含纖維之長度是否為基準值資料162所含之基準值以上(步驟ST27)。
On the other hand, when the humidity is lower than the reference value (step ST23; NO), the control unit 150 determines whether the length of the fiber contained in the mixture MX is greater than or equal to the reference value contained in the reference value data 162 (step ST27).
纖維之長度為基準值以上之情形時(步驟ST27；是)，控制部150設定
第4速度條件作為將第2篩馬達60a之速度加速之條件(步驟ST28)，結束設定處理。
When the length of the fiber is more than the reference value (step ST27; YES), the control unit 150 sets
The fourth speed condition is a condition for accelerating the speed of the second sieve motor 60a (step ST28), and the setting process is ended.
又，纖維之長度短於基準值之情形時(步驟ST27；否)，控制部150設定第5速度條件作為將第2篩馬達60a之速度加速之條件(步驟ST28)，結束設定處理。
When the length of the fiber is shorter than the reference value (step ST27; No), the control unit 150 sets the fifth speed condition as a condition for accelerating the speed of the second screen motor 60a (step ST28), and ends the setting process.
第1~第5速度條件為筒部61啟動時將速度VB自零加速之情形之基本條件，包含第2篩馬達60a之目標速度及達到目標速度為止之時間或第2篩馬達60a之加速度。
The first to fifth speed conditions are the basic conditions for the case where the cylinder 61 accelerates the speed VB from zero, including the target speed of the second screen motor 60a and the time until the target speed is reached or the acceleration of the second screen motor 60a.
速度VD之啟動相關之控制可採用圖8~圖12所示之態樣。即，藉由將圖8~圖12之各圖(1)所示之速度VB作為基於第2篩速度檢測部331之檢測值之速度VD，而可作為速度VD之速度相關之資料處理。
The control related to the start of the speed VD can adopt the form shown in Figs. 8-12. That is, by using the speed VB shown in each figure (1) of FIGS. 8 to 12 as the speed VD based on the detection value of the second sieve speed detection unit 331, it can be processed as speed-related data of the speed VD.
此處，速度VD之目標速度V1可與速度VB之目標速度V1相同，亦可為不同速度。
Here, the target speed V1 of the speed VD may be the same as the target speed V1 of the speed VB, or may be different speeds.
又，第2~第5速度條件下之加速時間可同樣地理解為與速度VD相關之加速時間。各速度條件下之加速時間之長短關係亦與上述第1實施形態相同。
In addition, the acceleration time under the second to fifth speed conditions can be similarly understood as the acceleration time related to the speed VD. The relationship between the length of the acceleration time under each speed condition is also the same as in the first embodiment described above.
第2實施形態中，藉由控制部150之控制，自筒部61下降至網帶72之混合物MX之量暫時變多之情形時，藉由控制筒部61啟動時之速度VD，而可抑制第2網片W2之厚度變動。藉此，於片材製造裝置100製造片材S
之步驟中，可使供給於第2網片形成部70之後續步驟之混合物MX之量穩定，可抑制片材S之品質變動。因此，可減輕用以抑制片材S之品質變動之人為的調整作業之負擔。
In the second embodiment, under the control of the control unit 150, when the amount of the mixture MX from the cylinder 61 to the mesh belt 72 temporarily increases, it can be suppressed by controlling the speed VD when the cylinder 61 starts The thickness of the second mesh W2 varies. With this, the sheet S is manufactured in the sheet manufacturing apparatus 100
In this step, the amount of the mixture MX supplied to the second mesh forming part 70 in the subsequent step can be stabilized, and the quality variation of the sheet S can be suppressed. Therefore, the burden of manual adjustment work for suppressing the quality variation of the sheet S can be reduced.
對速度VD設定之第1~第5速度條件可與第1實施形態中說明之第1~第5速度條件相同，亦可使用對筒部61之動作最佳化之第1~第5速度條件。
The first to fifth speed conditions set for the speed VD may be the same as the first to fifth speed conditions described in the first embodiment, and the first to fifth speed conditions optimized for the operation of the cylinder 61 may also be used .
如上說明，應用本發明之第2實施形態之片材製造裝置100具備筒部61，其篩選含有纖維之材料即混合物MX；及網帶72，其使自筒部61排出之混合物MX堆積。片材製造裝置100具備作為對堆積於網帶72之材料進行加工之加工部之製造部102之各部。在片材製造裝置100中，於製造片材S之動作中，筒部61以速度VD(第1速度)動作，筒部61自停止狀態啟動之情形時，於筒部61啟動後，執行包含以較第1速度更低速進行動作之狀態之啟動動作。此處，加工部可為第2網片形成部70之後續步驟之任一者，例如為成形部80或切斷部90。
As described above, the sheet manufacturing apparatus 100 to which the second embodiment of the present invention is applied includes the cylindrical portion 61 that screens the mixture MX that is the material containing fibers; and the mesh belt 72 that accumulates the mixture MX discharged from the cylindrical portion 61. The sheet manufacturing apparatus 100 includes each unit of the manufacturing unit 102 as a processing unit that processes the material deposited on the mesh belt 72. In the sheet manufacturing apparatus 100, during the operation of manufacturing the sheet S, the cylindrical portion 61 operates at a speed VD (first speed), and when the cylindrical portion 61 is started from a stopped state, after the cylindrical portion 61 is started, the execution includes The start-up operation is performed at a speed lower than the first speed. Here, the processing portion may be any of the subsequent steps of the second mesh forming portion 70, for example, the forming portion 80 or the cutting portion 90.
根據本發明之纖維處理裝置，及應用纖維處理裝置之控制方法之第2實施形態之片材製造裝置100，於自筒部61移動至網帶72之混合物MX之量易變動之啟動時，適當調整筒部61之動作速度。藉此，可抑制混合物MX量之變動。因此，可抑制第2網片W2之厚度變動，故於片材製造裝置100製造片材S之步驟中，可使供給於第2網片形成部70之後續步驟之混合物MX之量穩定化。例如，可抑制片材S之品質變動，可減輕用以使片材S
之品質穩定化之人為的調整作業之負擔。
According to the fiber processing apparatus of the present invention, and the sheet manufacturing apparatus 100 of the second embodiment applying the control method of the fiber processing apparatus, when the amount of the mixture MX moving from the cylindrical portion 61 to the mesh belt 72 is easily changed, it is appropriate Adjust the operating speed of the barrel 61. This can suppress the variation of the MX amount of the mixture. Therefore, the thickness variation of the second mesh W2 can be suppressed. Therefore, in the step of manufacturing the sheet S by the sheet manufacturing apparatus 100, the amount of the mixture MX supplied to the subsequent step of the second mesh forming portion 70 can be stabilized. For example, it is possible to suppress the quality variation of the sheet S, and to reduce the use of the sheet S
The burden of man-made adjustments to stabilize the quality.
片材製造裝置100於筒部61啟動後之啟動動作中，亦可將筒部61以較第1速度更低速進行動作之狀態維持特定時間。例如，如圖9~圖12所示之例，可維持速度VD未到達第1速度之狀態。藉此，於自筒部61下降之混合物MX之量易增大之時點，將速度VD維持在較第1速度更低速，故可有效抑制混合物MX量之變動。
The sheet manufacturing apparatus 100 may maintain the tube 61 at a lower speed than the first speed for a certain time during the start operation after the tube 61 is started. For example, as shown in the examples shown in FIGS. 9 to 12, the state where the speed VD does not reach the first speed can be maintained. As a result, at a time when the amount of the mixture MX descending from the cylinder portion 61 tends to increase, the speed VD is maintained at a lower speed than the first speed, so the change in the amount of the mixture MX can be effectively suppressed.
又，片材製造裝置100亦可於筒部61啟動後之啟動動作中，以將筒部61之動作速度較第1速度更低速之第2速度維持特定時間之方式使筒部61動作。該情形時，藉由將速度VD維持在低於第1速度之一定速度，而可有效抑制自筒部61移動至網帶72之混合物MX量之變動。
In addition, the sheet manufacturing apparatus 100 may also operate the cylindrical portion 61 in a startup operation after the cylindrical portion 61 is activated, to maintain the second speed at a lower speed than the first speed for a specific time. In this case, by maintaining the speed VD at a certain speed lower than the first speed, it is possible to effectively suppress the change in the amount of the mixture MX moving from the cylindrical portion 61 to the mesh belt 72.
又，片材製造裝置100亦可於筒部61啟動後之啟動動作中，以將筒部61之動作速度較第1速度更低速之狀態維持特定時間之方式使筒部61之動作速度變化。例如，可採用如圖11之例，使速度VD線形變化，或如圖12之例，使速度VD非線形變化之動作。該等情形時，由於速度VD維持在低於第1速度之狀態，故可有效抑制自筒部61移動至網帶72之混合物MX量之變動。
In addition, the sheet manufacturing apparatus 100 may change the operating speed of the cylindrical portion 61 so as to maintain the operating speed of the cylindrical portion 61 at a lower speed than the first speed for a specific time during the starting operation after the cylindrical portion 61 is activated. For example, an action such as changing the speed VD linearly as in the example of FIG. 11 or a non-linear change in the speed VD as in the example of FIG. 12 may be adopted. In such cases, since the speed VD is maintained at a state lower than the first speed, it is possible to effectively suppress the change in the amount of the mixture MX that moves from the cylinder 61 to the mesh belt 72.
又，在片材製造裝置100中，於筒部61中存在混合物MX之狀態下，筒部61自停止狀態啟動。該情形時，執行上述啟動動作。藉此，於自筒部61下降之混合物MX之量易增大之狀態下，控制速度VD，藉此可有效抑
制混合物MX量之變動。又，於自筒部61下降之混合物MX之量不易變動之狀態下，執行通常之啟動順序，故可防止片材S之製造效率之降低。
In addition, in the sheet manufacturing apparatus 100, when the mixture MX is present in the cylindrical portion 61, the cylindrical portion 61 is started from the stopped state. In this case, the above start-up action is performed. By this, the speed VD is controlled in a state where the amount of the mixture MX descending from the barrel portion 61 is easy to increase, thereby effectively suppressing
Changes in the amount of MX in the mixture. In addition, in a state where the amount of the mixture MX descending from the tube portion 61 is not easily changed, the normal start-up sequence is performed, so that the reduction in the manufacturing efficiency of the sheet S can be prevented.
片材製造裝置100藉由控制部150控制筒部61之動作。控制部150於片材S之製造中，基於第1速度使筒部61動作。筒部61啟動後，基於較第1速度更低速之設定速度，使筒部61動作特定時間。設定速度於第2實施形態中應用圖9之控制之情形時，相當於中間速度V2，在圖10之例中相當於中間速度V4、V5。該情形時，藉由以速度VD成為低於第1速度之速度之方式進行控制，而可有效抑制自筒部61移動至網帶72之混合物MX量之變動。
The sheet manufacturing apparatus 100 controls the operation of the tube portion 61 by the control portion 150. In the manufacture of the sheet S, the control unit 150 operates the cylinder 61 based on the first speed. After the cylinder 61 is started, the cylinder 61 is operated for a specific time based on the set speed lower than the first speed. The set speed corresponds to the intermediate speed V2 when the control of FIG. 9 is applied in the second embodiment, and corresponds to the intermediate speeds V4 and V5 in the example of FIG. 10. In this case, by controlling the speed VD to be lower than the first speed, it is possible to effectively suppress the change in the amount of the mixture MX moving from the cylinder 61 to the mesh belt 72.
又，片材製造裝置100具備檢測濕度之第2溫濕度檢測部333。控制部150對應於以第2溫濕度檢測部333檢測出之濕度之資訊，控制設定速度。因此，可適當因應因濕度變動所致之混合物MX量之變動，可有效抑制混合物MX量之變動。例如，如上述，筒部61內之濕度愈高，通過開口61a之混合物MX量之變動愈少。又，若筒部61內之濕度較低，則混合物MX所含之纖維之帶電不易緩和，易大幅產生纖維之凝集，故纖維凝集被解開之量較大。因此，筒部61內之濕度愈低，通過開口61a之混合物MX量之變動愈大。例如，可由第2溫濕度檢測部333之檢測值檢測或推測筒部61內之濕度之情形時，可藉由對應於筒部61內之濕度控制設定速度，而適當應對因濕度影響所致之混合物MX量之變動。
In addition, the sheet manufacturing apparatus 100 includes a second temperature and humidity detection unit 333 that detects humidity. The control unit 150 controls the set speed in accordance with the humidity information detected by the second temperature and humidity detection unit 333. Therefore, it is possible to appropriately respond to changes in the amount of MX in the mixture due to changes in humidity, and to effectively suppress changes in the amount of MX in the mixture. For example, as described above, the higher the humidity in the cylinder 61, the less the change in the amount of the mixture MX passing through the opening 61a. In addition, if the humidity in the cylindrical portion 61 is low, the charging of the fibers contained in the mixture MX is not easy to relax, and the fiber aggregation is likely to be greatly generated, so the amount of fiber aggregation is released is large. Therefore, the lower the humidity in the cylinder 61, the greater the variation in the amount of the mixture MX passing through the opening 61a. For example, when the detection value of the second temperature and humidity detection unit 333 detects or estimates the humidity in the barrel 61, the speed set corresponding to the humidity in the barrel 61 can be controlled to appropriately respond to the effects caused by the humidity Changes in the amount of MX in the mixture.
又，筒部61構成為圓筒形狀，於筒部61之周面設有開口，且以圓筒
之軸為中心而旋轉。因此，若於筒部61之內部存在混合物MX之狀態下啟動筒部61，則於啟動時下降至網帶72之混合物MX之量易變動。該構成中，藉由控制部150之控制，確保筒部61以較第1速度更低速旋轉之期間，故可抑制混合物MX量之變動。
In addition, the cylindrical portion 61 is configured into a cylindrical shape, an opening is provided on the peripheral surface of the cylindrical portion 61, and the cylindrical
The axis rotates around the center. Therefore, if the cylinder portion 61 is activated in the state where the mixture MX is present inside the cylinder portion 61, the amount of the mixture MX that drops to the mesh belt 72 at the time of activation is likely to vary. In this configuration, under the control of the control unit 150, the period during which the cylindrical portion 61 rotates at a lower speed than the first speed is ensured, so that the variation in the amount of the mixture MX can be suppressed.
應用本發明之纖維原料再生裝置之片材製造裝置100具備作為將含有纖維之原料MA微細化之微細化部之解纖部20。片材製造裝置100具備：筒部61，其篩選藉由微細化部予以微細化之混合物MX；及作為堆積部之網帶72，其使自筒部61排出之混合物MX堆積。片材製造裝置100具備製造部102之各部，作為對堆積於網帶72之混合物MX進行加工之加工部。又，片材製造裝置100於片材S之製造中即加工部之加工執行中，使筒部61以第1速度動作。在片材製造裝置100中，於筒部41中存在混合物MX之狀態下，筒部61自停止狀態啟動之情形時，於筒部61啟動後，執行包含筒部61以較第1速度更低速動作之狀態之啟動動作。根據該構成，混合物MX自筒部61移動之量易變動之狀態下，藉由將筒部61之速度設為較第1速度更低速，而可抑制混合物MX量之變動。
The sheet manufacturing apparatus 100 to which the fiber material recycling device of the present invention is applied includes a defibrating unit 20 as a miniaturizing unit that miniaturizes a fiber-containing material MA. The sheet manufacturing apparatus 100 includes a cylindrical portion 61 that screens the mixture MX that has been refined by the refining portion, and a mesh belt 72 as a stacking portion that stacks the mixture MX discharged from the cylindrical portion 61. The sheet manufacturing apparatus 100 includes each section of the manufacturing section 102 as a processing section that processes the mixture MX deposited on the mesh belt 72. In addition, the sheet manufacturing apparatus 100 operates the tubular portion 61 at the first speed during the manufacture of the sheet S, that is, during the processing of the processing portion. In the sheet manufacturing apparatus 100, in a state where the mixture MX is present in the cylinder 41, when the cylinder 61 starts from the stop state, after the cylinder 61 is started, the cylinder 61 is included at a lower speed than the first speed. The start action of the action state. According to this configuration, in a state where the amount of movement of the mixture MX from the cylindrical portion 61 is likely to fluctuate, by setting the speed of the cylindrical portion 61 to be lower than the first speed, the fluctuation of the amount of the mixture MX can be suppressed.
第2實施形態中，使筒部61之速度VD變化之態樣不限於圖9~圖12所示之例。例如，於筒部61啟動後，亦可使速度VD較第1速度更高速。具體而言，控制部150亦可為如下態樣：於筒部61啟動之情形時使速度VD加速至較第1速度更高速，於加速完成後之特定時間，維持筒部61以不同於第1速度之速度VD動作之狀態。如此，於啟動動作中，執行包含使筒部61之加速度隨時間而增大之第1動作、及於上述時間經過後使筒部61之加速
度減少之第2動作之情形時，藉由使筒部61之速度變化適當，而可將混合物MX量之變動減緩。例如，藉由以控制部150控制筒部61之加速度之變化，而可抑制因筒部61之加速度變化而施加於筒部61內之混合物MX之力。該情形時，可期待將混合物MX量之變動減緩之效果。
In the second embodiment, the manner of changing the speed VD of the cylindrical portion 61 is not limited to the examples shown in FIGS. 9 to 12. For example, after the cylinder 61 is activated, the speed VD may be higher than the first speed. Specifically, the control unit 150 may be as follows: when the barrel 61 is activated, the speed VD is accelerated to a higher speed than the first speed, and the barrel 61 is maintained to be different from the first speed at a specific time after the acceleration is completed. 1 State of speed VD action. In this way, during the start-up operation, the first operation including increasing the acceleration of the cylinder 61 with time, and accelerating the cylinder 61 after the above time has passed
In the case of the second action in which the degree is reduced, by appropriately changing the speed of the cylinder 61, the change in the amount of MX of the mixture can be reduced. For example, by controlling the change in the acceleration of the cylinder 61 with the control unit 150, the force applied to the mixture MX in the cylinder 61 due to the change in the acceleration of the cylinder 61 can be suppressed. In this case, the effect of mitigating the change in the amount of MX in the mixture can be expected.
