　本発明は、ガラス板用合紙のクリーニング装置及びクリーニング方法及びガラス板積層体及びガラス板梱包体及びガラス板用合紙の製造方法並びガラス板用合紙に関する。 The present invention relates to a cleaning device and cleaning method for glass sheet interleaving paper, a glass sheet laminate, a glass sheet packing body, a method for producing glass sheet interleaving paper, and glass sheet interleaving paper.
　特許文献１には、液晶ディスプレイ、プラズマディスプレイ等のＦＰＤ（Flat Panel Display）に用いられるガラス板を、緩衝材としての合紙を介して積層し、この積層体を梱包するパレットが開示されている。 Patent Document 1 discloses a pallet for laminating a glass plate used for FPD (Flat Panel Display) such as a liquid crystal display and a plasma display through a slip sheet as a cushioning material, and packing the laminated body. .
　前記積層体は、ガラス板製造工場にてパレットに梱包された後、ディスプレイ組立工場にトラック等の輸送手段によって輸送される。 The laminate is packed in a pallet at a glass plate manufacturing factory and then transported to a display assembly factory by a transportation means such as a truck.
　前記積層体に使用される合紙は、合紙ロールから帯状の合紙を引き出し、帯状の合紙をカッターによって所定のサイズに切り出すことによって使用される。合紙としては、バージンパルプを原料としたもの、セルロースを含有したもの、又は古紙が使用される。 The slip sheet used for the laminate is used by pulling out a strip-shaped slip sheet from a slip-sheet roll and cutting the strip-shaped slip sheet into a predetermined size by a cutter.

　ところで、ガラス板は、その表裏面が合紙に圧接された状態で積層されるため、ガラス板の表裏面に、合紙の異物が付着するという問題がある。 By the way, since the glass plate is laminated in a state where the front and back surfaces thereof are pressed against the slip sheet, there is a problem that foreign matter of the slip sheet adheres to the front and back surfaces of the glass plate.
　ガラス板の表裏面に付着した前記異物は、前記洗浄工程にて除去されるものの、異物の付着量が多い場合には、洗浄により取りきれない異物が発生し品質の低下を招く。 Although the foreign matter adhering to the front and back surfaces of the glass plate is removed in the cleaning step, when the amount of foreign matter attached is large, foreign matter that cannot be removed by the cleaning is generated and quality is deteriorated.
　よって、積層体の状態において、ガラス板の表裏面に付着する前記異物の付着量を低減できれば、ガラス板の品質を向上することが可能になり機能層形成工程以後の後工程の歩留まりが向上するという利点がある。 Therefore, if the amount of the foreign matter adhering to the front and back surfaces of the glass plate can be reduced in the state of the laminated body, the quality of the glass plate can be improved, and the yield of subsequent processes after the functional layer forming process is improved. There is an advantage.
　なお、ガラス板に付着する合紙の異物とは、合紙に存在するパルプ及び粘着性異物等の樹脂成分の屑をいい、ここでは総じてパーティクルともいう。また、前記粘着性異物とは、合紙を製造する段階で古紙を混入した際に、古紙回収ルートの途中で古紙に貼着されていた粘着テープ等の完全に固化されていない粘着成分、又は紙から脱落した紙粉や紙中に含まれる粘着性の樹脂分をいう。 In addition, the foreign material of the slip sheet adhering to the glass plate refers to resin component waste such as pulp and adhesive foreign matter existing in the slip sheet, and is also generally referred to as a particle herein. In addition, the adhesive foreign matter is an adhesive component that is not completely solidified, such as an adhesive tape that has been attached to the used paper in the middle of the used paper collection route when the used paper is mixed in the step of manufacturing the slip paper, or Paper dust that has fallen off the paper and the adhesive resin content contained in the paper.
　本発明は、このような事情に鑑みてなされたもので、合紙からガラス板に付着する異物の付着量を低減することができるガラス板用合紙のクリーニング装置及びクリーニング方法及びガラス板積層体及びガラス板梱包体及びガラス板用合紙の製造方法並びにガラス板用合紙を提供することを目的とする。 The present invention has been made in view of such circumstances, and is capable of reducing the amount of foreign matter adhering to the glass plate from the interleaving paper. It is another object of the present invention to provide a glass plate package, a method for producing a glass plate interleaf, and a glass plate interleaf.
　本発明の一態様のガラス板用合紙のクリーニング装置は、前記目的を達成するために、複数枚のガラス板の各々のガラス板間に介在される合紙に対し、前記合紙の表裏面のうち少なくとも一面に当接して異物を掻き出すブラシ手段と、前記ブラシ手段によって掻き出した前記異物を前記合紙から吸引除去する吸引手段と、を備える。 In order to achieve the above object, a glass sheet slip sheet cleaning device according to an aspect of the present invention is provided with front and back surfaces of a slip sheet with respect to a slip sheet interposed between each glass sheet of a plurality of glass sheets. A brush unit that abuts against at least one surface and scrapes out the foreign matter, and a suction unit that sucks and removes the foreign matter scraped out by the brush unit from the slip sheet.
　本発明の一態様のガラス板用合紙のクリーニング方法は、前記目的を達成するために、複数枚のガラス板の各々のガラス板間に介在される合紙に対し、前記合紙の表裏面のうち少なくとも一面をブラシ手段によって擦り、前記一面の表層に存在する異物を掻き出すとともに、掻き出した前記異物を吸引手段によって前記合紙から吸引除去する。 In order to achieve the above object, a method for cleaning a glass sheet slip sheet according to an aspect of the present invention is performed on the front and back surfaces of the slip sheet with respect to a slip sheet interposed between each glass sheet of a plurality of glass sheets. At least one surface is rubbed with a brush means to scrape out foreign matter existing on the surface layer of the one surface, and the scraped-out foreign matter is sucked and removed from the interleaf by a suction means.
　本発明の一態様のガラス板積層体は、前記目的を達成するために、本発明のガラス板用合紙のクリーニング方法によって異物が除去された合紙が、複数枚のガラス板の各々のガラス板間に介在されてなる。 In order to achieve the above object, the glass sheet laminate of one embodiment of the present invention is a glass sheet in which a foreign material is removed by the method for cleaning a glass sheet slip sheet of the present invention. It is interposed between the plates.
　本発明の一態様のガラス板梱包体は、前記目的を達成するために、本発明のガラス板積層体が梱包容器に梱包されてなる。 The glass plate package of one aspect of the present invention is formed by packing the glass plate laminate of the present invention in a packing container in order to achieve the above-described object.
　本発明の一態様のガラス板用合紙の製造方法は、前記目的を達成するために、本発明のガラス板用合紙のクリーニング方法によって異物を除去する工程を含む。 In order to achieve the above object, the method for producing a glass sheet slip sheet according to one aspect of the present invention includes a step of removing foreign matters by the glass sheet slip sheet cleaning method of the present invention.
　本発明の一態様のガラス板用合紙は、前記目的を達成するために、複数枚のガラス板の各々のガラス板間に介在される合紙であって、クラス１００００のクリーンルームにてＡ４サイズの前記合紙を重ねて１往復／ｓｅｃで擦り合わせたときの発塵量（１ｆｔ３の立方体中の０．５μｍ以上の異物の数）が１００００個以下となる。 In order to achieve the above object, a slip sheet for a glass plate according to an aspect of the present invention is a slip sheet interposed between glass plates of a plurality of glass plates, and is A4 size in a class 10000 clean room. The dust generation amount (the number of foreign matters of 0.5 μm or more in a 1 ft 3 cube) when the slip sheets are overlapped and rubbed at 1 reciprocation / sec is 10,000 or less.
　本発明の一態様によれば、合紙の一面をブラシ手段によって擦り、一面に存在する異物を掻き出し、掻き出した異物が一面に再付着しないように、掻き出した異物を吸引手段によって吸引除去する。これにより、本発明の一態様によれば、合紙の一面からガラス板に付着する異物の付着量を低減することができる。例えば、合紙の一面からガラス板に付着した所定の大きさを有するパーティクル（例えば直径１μｍ以上）の個数を約４０％低減することができる。 According to one aspect of the present invention, one surface of the slip sheet is rubbed by the brush means, the foreign matter existing on the one surface is scraped, and the scraped foreign matter is sucked and removed by the suction means so that the scraped foreign matter does not reattach to the one surface. Thereby, according to 1 aspect of this invention, the adhesion amount of the foreign material adhering to a glass plate from the one surface of a slip sheet can be reduced. For example, the number of particles having a predetermined size (for example, a diameter of 1 μm or more) attached to the glass plate from one surface of the slip sheet can be reduced by about 40%.
　また、異物を掻き出して異物を吸引除去（以下、「クリーニング」ともいう。）した合紙を使用することにより、異物の付着量を低減したガラス板積層体、及びこのガラス板積層体を梱包容器に梱包してなるガラス板梱包体を提供できる。 In addition, a glass sheet laminate in which the amount of foreign matter adhered is reduced by using a slip sheet in which the foreign substances are scraped and removed by suction (hereinafter also referred to as “cleaning”), and the glass plate laminate is packed in a packaging container.

In addition, a pair of openings 30 for inserting and removing forklift claws (not shown) is provided on the front surface of the base 18.
　底受け板２０は、搭載面２８と底受け板２０との間に配置された複数の三角形状の底片３２を介して搭載面２８上に傾斜して載置される。また、底受け板２０は、その主面が台座１８の搭載面２８に対して好ましくは５°～２５°、より好ましくは１０°～２０°、特に好ましくは約１８°に傾斜して配置される。これにより、ガラス板積載装置（不図示）によるパレット１４へのガラス板積載時に、ガラス板Ｇの位置決め作業が容易になる。また、各ガラス板Ｇの主面は自重によって背受け板２４側のガラス板Ｇの主面に接するので、各ガラス板Ｇの主面間に無駄な隙間が生じることはない。更に、載置するガラス板Ｇの安定化を図ることができ、ガラス板Ｇの前方（図１の矢印Ｘの方向）へのずれや崩壊を防止でき、併せて傷や割れを防止できる。 The bottom receiving plate 20 is inclined and placed on the mounting surface 28 via a plurality of triangular bottom pieces 32 disposed between the mounting surface 28 and the bottom receiving plate 20. The bottom receiving plate 20 is arranged such that its main surface is inclined with respect to the mounting surface 28 of the pedestal 18 preferably at 5 ° to 25 °, more preferably 10 ° to 20 °, and particularly preferably about 18 °. The This facilitates the positioning operation of the glass plate G when the glass plate is loaded on the pallet 14 by the glass plate loading device (not shown). Further, since the main surface of each glass plate G is in contact with the main surface of the glass plate G on the back plate 24 side by its own weight, no useless gap is generated between the main surfaces of the glass plates G. Furthermore, the glass plate G to be placed can be stabilized, the glass plate G can be prevented from shifting or collapsing forward (in the direction of the arrow X in FIG. 1), and at the same time, scratches and cracks can be prevented.
　なお、図１に示したパレット１４に、積層体１２のＹ方向の横ずれを規制する横押さえ部材を設けてもよい。また、図１に示したパレット１４は、積層体１２を縦積みするパレットであるが、積層体１２を水平方向に平積みする形態のパレットであってもよい。すなわち、積層体１２がパレットに梱包されてなる梱包体は、図１、図２の梱包体１６に限定されるものではない。 In addition, you may provide the horizontal pressing member which regulates the lateral shift | offset | difference of the laminated body 12 in the Y direction on the pallet 14 shown in FIG. Moreover, although the pallet 14 shown in FIG. 1 is a pallet which stacks the laminated bodies 12 vertically, the pallet of the form which laminates | stacks the laminated bodies 12 in a horizontal direction may be sufficient. That is, the packaging body in which the laminated body 12 is packaged on a pallet is not limited to the packaging body 16 in FIGS.
　〔積層体１２〕
　積層体１２は、パレット１４に対し、複数枚のガラス板Ｇと複数枚の合紙１０とを交互に積層することにより構成される。 [Laminate 12]
The laminated body 12 is configured by alternately laminating a plurality of glass plates G and a plurality of interleaving papers 10 on the pallet 14.
　〈ガラス板Ｇ〉
　ガラス板Ｇは、液晶ディスプレイ用等のＦＰＤ用ガラス板に使用されるものであり、その厚さは０．７ｍｍ以下であることが好ましい。また、ガラス板Ｇは、第５世代（Ｇ５）と称される縦約１３００ｍｍ×横約１１００ｍｍのサイズのガラス板であるが、ガラス板Ｇのサイズは、第５世代に限定されるものではなく、第６世代（縦約１５００ｍｍ×横約１８００ｍｍ）以上のサイズまたは第５世代未満のガラス板であってもよい。 <Glass plate G>
The glass plate G is used for FPD glass plates for liquid crystal displays and the like, and the thickness is preferably 0.7 mm or less. Further, the glass plate G is a glass plate having a size of about 1300 mm in length and about 1100 mm in width called a fifth generation (G5), but the size of the glass plate G is not limited to the fifth generation. The glass plate may have a size of the sixth generation (approximately 1500 mm long × approximately 1800 mm wide) or a glass plate of less than the fifth generation.
　〈合紙１０〉
　合紙１０は、ガラス板Ｇを保護するために、ガラス板Ｇよりも大きいサイズの紙である。また、合紙１０の上部片１０Ａは、合紙１０からガラス板Ｇを引き剥がす際に、合紙用吸着部材（不図示）に吸着保持されるため、ガラス板Ｇの上縁から所定量（例えば５０～１００ｍｍ）食み出される。また、合紙１０の側部片１０Ｂも同様に、合紙１０からガラス板Ｇを引き剥がす際に、前記合紙用吸着部材に吸着保持されるため、ガラス板Ｇの側縁から所定量（例えば５０～１００ｍｍ）食み出される。 <Interleaf 10>
In order to protect the glass plate G, the interleaf paper 10 is a paper having a size larger than that of the glass plate G. Further, since the upper piece 10A of the interleaf paper 10 is adsorbed and held by an adsorbing member for interleaf paper (not shown) when the glass plate G is peeled off from the interleaf paper 10, a predetermined amount (from the upper edge of the glass plate G) For example, 50 to 100 mm). Similarly, the side piece 10 </ b> B of the slip sheet 10 is also sucked and held by the slip sheet suction member when the glass sheet G is peeled off from the slip sheet 10, so that a predetermined amount (from the side edge of the slip sheet 10 ( For example, 50 to 100 mm).
　また、本実施形態の合紙１０は、発塵量が少なくなるように製造される。合紙１０の発塵量は、以下に説明する測定方法にて異物が１００００個以下となるものであり、好ましくは８０００個以下、さらに好ましくは５０００個以下となるものである。発塵量の測定方法は、次のとおりである。Ａ４サイズに切り出した２枚の合紙１０を用意する。クラス１００００のクリーンルーム内に、内寸法が３０５×３０５×３０５ｍｍの空間を有する立方体を準備する。立法体は１つの面が開口していて、そこから合紙の取り出しが可能である。この立方体内で切り出した合紙１０を重ねて両手で擦り合わせる。擦り合わせは、１往復／ｓｅｃの速度にて１０回実施する。このときの立方体内の粒径が０．５μｍ以上の異物の数をパーティクルカウンターにて測定する。これを発塵量（１ｆｔ３の立方体中の０．５μｍ以上の異物の数）とする。 Further, the slip sheet 10 of the present embodiment is manufactured so that the amount of dust generation is reduced. The dust generation amount of the interleaf paper 10 is such that the number of foreign matters is 10,000 or less, preferably 8000 or less, and more preferably 5000 or less, by the measurement method described below. The method for measuring the amount of dust generation is as follows. Two slip sheets 10 cut out to A4 size are prepared. A cube having a space of 305 × 305 × 305 mm is prepared in a clean room of class 10000. The legislature has an opening on one side, from which the slip sheet can be taken out. The slip sheets 10 cut out in the cube are stacked and rubbed with both hands. The rubbing is performed 10 times at a speed of 1 reciprocation / sec. At this time, the number of foreign matters having a particle size of 0.5 μm or more in the cube is measured with a particle counter. This is the dust generation amount (the number of foreign matters of 0.5 μm or more in a 1 ft 3 cube).
　なお、合紙１０の原料は、バージンパルプが好ましいが、セルロース等を含有している原料でもよく古紙でもよい。また、合紙１０中の有機化合物の含有量が０．０８質量％以下であることが好ましい。有機化合物の含有量が０．０８質量％以下であると、ガラス板に有機化合物が転写しにくくなる。ここでいう有機化合物とは、ＪＩＳ　Ｐ８２２４にて測定される合紙１０の樹脂分である。 The raw material of the interleaf paper 10 is preferably virgin pulp, but it may be a raw material containing cellulose or the like or used paper. Moreover, it is preferable that content of the organic compound in the interleaving paper 10 is 0.08 mass% or less. When the content of the organic compound is 0.08% by mass or less, it becomes difficult to transfer the organic compound to the glass plate. An organic compound here is the resin part of the slip sheet 10 measured by JIS P8224.
　ガラス板用合紙１０の製造方法としては以下のとおりである。
　まず、紙原料液（パルプを水で希釈した液体）を均一の厚さになるようにシート状に広げ、脱水して、湿紙（紙）を形成させる。湿紙は、プレスローラや無端帯状のフェルトなどによって、さらなる脱水とプレスとが同時に行われる。脱水されプレスされた湿紙は、１００～１５０℃の雰囲気で乾燥される。この工程を経ることで紙の状態となる。 The manufacturing method of the interleaf paper 10 for glass plate is as follows.
First, a paper raw material liquid (liquid obtained by diluting pulp with water) is spread in a sheet shape so as to have a uniform thickness and dehydrated to form wet paper (paper). The wet paper is further dewatered and pressed simultaneously by a press roller, an endless belt-like felt or the like. The dewatered and pressed wet paper is dried in an atmosphere of 100 to 150 ° C. A paper state is obtained through this process.
　乾燥された紙は、必要に応じて、カレンダロールによる挟持搬送等によってカレンダ処理を施されて、表裏面を平滑化してもよい。また、乾燥とカレンダ処理との間で、平滑化された紙の表面に塗料等を塗布してもよい。以上の工程を経た紙は、ガラス板用合紙としてリール等に巻き取られ、ロール状にされる。 The dried paper may be subjected to a calendering process such as nipping and conveying with a calender roll as necessary to smooth the front and back surfaces. Further, a paint or the like may be applied to the smoothed paper surface between the drying and the calendering process. The paper that has undergone the above steps is wound on a reel or the like as a glass sheet slip sheet, and is rolled.
　なお、合紙１０は、紙原料液を調製する前に、原料となるパルプの洗浄を行ってもよいし、湿紙を乾燥させる前にシャワー洗浄を行ってもよい。このような洗浄工程を経ることにより、合紙１０中の異物を減少させることができる。 Note that the interleaf paper 10 may be washed with pulp as a raw material before preparing a paper raw material solution, or shower washed before drying wet paper. By going through such a cleaning process, foreign matter in the interleaf paper 10 can be reduced.
　また、合紙１０は、後述する実施形態のクリーニング装置によって、その表裏面に存在する異物が除去されたものである。すなわち、合紙１０の表裏面のうち少なくとも一面をブラシ手段によって擦り、一面の表層に存在する異物を掻き出すとともに、掻き出した異物を吸引手段によって合紙から吸引除去する工程を含んでいる。この工程は、合紙をロール状に巻き取る前に実施してもよいし、ロール状に巻き取られた合紙から送り出した帯状の合紙に実施してもよい。 Further, the interleaf paper 10 is obtained by removing foreign substances existing on the front and back surfaces thereof by a cleaning device according to an embodiment described later. That is, it includes a step of rubbing at least one of the front and back surfaces of the interleaving paper 10 with the brush means, scraping out the foreign matter existing on the surface layer of the one surface, and sucking and removing the scraped foreign matter from the interleaving paper with the suction means. This step may be performed before winding the interleaf into a roll, or may be performed on a strip of interleaf fed from the interleaf that has been wound into a roll.

　〈第１の実施形態のクリーニング装置４０の構成〉
　図３（Ａ）は、第１の実施形態のクリーニング装置４０の側面図、図３（Ｂ）は、クリーニング装置４０の要部平面図である。 [Cleaning device]
<Configuration of Cleaning Device 40 of First Embodiment>
FIG. 3A is a side view of the cleaning device 40 according to the first embodiment, and FIG. 3B is a plan view of the main part of the cleaning device 40.
　クリーニング装置４０は、複数のディスクブラシ（ブラシ手段）４２、複数の吸引装置（吸引手段）４４、合紙供給装置（合紙供給手段）４６、及び合紙巻取装置（合紙巻取手段）４８から構成される。 The cleaning device 40 includes a plurality of disc brushes (brush means) 42, a plurality of suction devices (suction means) 44, a slip sheet supply device (slip sheet supply means) 46, and a slip sheet take-up device (slip sheet take-up means) 48. Composed.
　複数のディスクブラシ４２、複数の吸引装置４４は、合紙供給装置４６と合紙巻取装置４８との間の合紙走行経路５０において、帯状の合紙１１を挟んで上下の対称位置に一対配置される。合紙１１の上下に配置された複数のディスクブラシ４２、２台の吸引装置４４は同一構成なので、ここでは、上方に配置された複数のディスクブラシ４２、２台の吸引装置４４について説明し、下方に配置された複数のディスクブラシ４２、２台の吸引装置４４については同一の符号を付して説明は省略する。 A plurality of disk brushes 42 and a plurality of suction devices 44 are arranged in a symmetrical position on the upper and lower sides of the belt-like interleaf 11 in the interleaf travel path 50 between the interleaf feeding device 46 and the interleaf take-up device 48. Is done. Since the plurality of disc brushes 42 and the two suction devices 44 arranged above and below the slip sheet 11 have the same configuration, here, the plurality of disc brushes 42 and the two suction devices 44 arranged above are described. The plurality of disk brushes 42 and the two suction devices 44 arranged below are assigned the same reference numerals and description thereof is omitted.
　〈合紙供給装置４６、合紙巻取装置４８〉
　合紙供給装置４６には、クリーニング前の帯状の合紙１１がロール状に巻き取られて配置される。この合紙１１は、合紙供給装置４６の巻取軸５２に巻き取られており、巻取軸５２をモータ５４によって送り出し方向に回転させることにより矢印Ｂ方向に送り出される。送り出された合紙１１は、合紙走行経路５０を通過する際にディスクブラシ４２及び吸引装置４４によって、表面および裏面に存在する異物４５が除去されてクリーニングされた後、合紙巻取装置４８の巻取軸５６に巻き取られる。巻取軸５６は、モータ５８によって巻き取り方向に回転される。 <Interleaf Supply Device 46, Interleaf Paper Winding Device 48>
In the slip sheet supply device 46, the strip-shaped slip sheet 11 before cleaning is wound up in a roll shape and disposed. The interleaf paper 11 is wound around a take-up shaft 52 of the interleaf supply device 46, and is sent out in the direction of arrow B by rotating the take-up shaft 52 in the feed direction by a motor 54. When the interleaving paper 11 passes through the interleaving paper travel path 50, the disc brush 42 and the suction device 44 remove and clean the foreign matter 45 existing on the front and back surfaces, and then the interleaving paper take-up device 48 It is wound around the winding shaft 56. The winding shaft 56 is rotated in the winding direction by a motor 58.
　ここで、ディスクブラシ４２による異物４５の掻き出し時において、合紙走行経路５０を通過する合紙１１に所定のテンションを付加し、ディスクブラシ４２で押しつけて圧を加えても合紙１１に皺を発生させないことが、異物４５の掻き出し性能を向上させる点で好ましい。 Here, when scraping out the foreign matter 45 by the disc brush 42, even if a predetermined tension is applied to the interleaf paper 11 passing through the interleaf travel path 50 and the disc brush 42 presses and applies pressure, the interleaf paper 11 is wrinkled. It is preferable not to generate it in terms of improving the scraping performance of the foreign matter 45.
　テンションを付加する機能としては、モータ５８による巻取速度を、モータ５４による送り出し速度よりも高速に設定し、かつ合紙供給装置４６の巻取軸５２にトルク制限装置を設けることが好ましい。トルク制限装置とは、所定のトルク以上のトルクが巻取軸５２に負荷された際に、巻取軸５２をモータ５４の動力伝達系に対してスリップさせて、巻取軸５２を巻取軸５６のトルクのみに依存させて回転させる装置である。トルク制限装置を設けることにより、合紙走行経路５０を走行中の合紙１１は、常にテンションが付加されているので、ディスクブラシ４２による異物４５の掻き出しが良好に行われる。 As a function of adding tension, it is preferable to set the winding speed by the motor 58 to be higher than the feeding speed by the motor 54 and to provide a torque limiting device on the winding shaft 52 of the interleaf feeder 46. The torque limiter means that when a torque greater than a predetermined torque is applied to the take-up shaft 52, the take-up shaft 52 is slipped with respect to the power transmission system of the motor 54 so that the take-up shaft 52 is taken up. It is a device that rotates depending on only 56 torque. By providing the torque limiting device, since the tension is always applied to the slip sheet 11 traveling along the slip sheet travel path 50, the foreign matter 45 is scraped out by the disc brush 42 satisfactorily.
　なお、トルク制限装置に代えて、合紙１１の主面に対して垂直方向に移動するダンサーローラに合紙１１を巻回し、合紙走行経路５０を走行中の合紙１１にテンションを付加させてもよい。また、合紙１１の走行速度は、ディスクブラシ４２及び吸引装置４４によるクリーニング能力が十分に発揮できる速度に適宜設定されるものである。 Instead of the torque limiting device, the slip sheet 11 is wound around a dancer roller that moves in a direction perpendicular to the main surface of the slip sheet 11, and tension is applied to the slip sheet 11 that is traveling along the slip sheet travel path 50. May be. The traveling speed of the interleaf paper 11 is appropriately set to a speed at which the cleaning ability of the disc brush 42 and the suction device 44 can be sufficiently exhibited.
　〈ディスクブラシ４２〉
　ディスクブラシ４２は、円盤状の支持体に複数本の軟性毛材が植設されて構成され、軟性毛材の先端部が所定の圧力（面圧）を持って合紙１１の表裏面に当接される。また、モータ６０からの動力が伝達されて矢印Ｃの如く回転される。これにより、合紙１１の表裏面に存在する異物が掻き出される。ディスクブラシ４２の回転軸Ｐ１は、合紙１１の主面に対して垂直方向に設定されるが、垂直方向とは厳密な垂直方向を意味するものではなく、ディスクブラシ４２によるクリーニング性能を担保できる許容範囲において傾斜した角度を含むものである。 <Disc brush 42>
The disc brush 42 is configured by implanting a plurality of soft bristle materials on a disk-shaped support, and the tip of the soft bristle material has a predetermined pressure (surface pressure) applied to the front and back surfaces of the interleaf paper 11. Touched. Further, the power from the motor 60 is transmitted and rotated as indicated by an arrow C. Thereby, the foreign material which exists in the front and back of the slip sheet 11 is scraped off. The rotation axis P1 of the disc brush 42 is set in a direction perpendicular to the main surface of the interleaf paper 11, but the vertical direction does not mean a strict vertical direction, and the cleaning performance by the disc brush 42 can be ensured. It includes an angle that is inclined within an allowable range.
　ディスクブラシ４２は、図３（Ｂ）に示すように、合紙１１の矢印Ｂで示す送り出し方向に対し、直交する方向である合紙１１の幅方向（図３（Ｂ）のＷ方向）に所定の間隔を持って配置される。また、ディスクブラシ４２はジグザグ状に配置されており、複数のディスクブラシ４２を通過する合紙１１の全面が複数のディスクブラシ４２によって擦られる構成となっている。 As shown in FIG. 3 (B), the disc brush 42 extends in the width direction of the slip sheet 11 (W direction in FIG. 3 (B)) that is orthogonal to the feed direction indicated by the arrow B of the slip sheet 11. They are arranged with a predetermined interval. The disk brushes 42 are arranged in a zigzag shape, and the entire surface of the slip sheet 11 passing through the plurality of disk brushes 42 is rubbed by the plurality of disk brushes 42.
　〈吸引装置４４〉
　吸引装置４４は、ディスクブラシ４２に対し、合紙１１の走行方向の上流側及び下流側にディスクブラシ４２に近接して配置される。 <Suction device 44>
The suction device 44 is disposed adjacent to the disc brush 42 on the upstream side and the downstream side in the traveling direction of the interleaf paper 11 with respect to the disc brush 42.
　吸引装置４４は、合紙１１の矢印Ｂで示す送り出し方向に対し、直交する方向に長手軸を有する筐体６２、及び吸引ポンプ６４を備えて構成される。 The suction device 44 includes a housing 62 having a longitudinal axis in a direction orthogonal to the feed direction indicated by the arrow B of the slip sheet 11 and a suction pump 64.
　吸引装置４４の配置位置は、前記上流側及び下流側の２箇所に限定されず、少なくとも下流側に設置すればよい。上流側の吸引装置４４は、ディスクブラシ４２による異物掻き出し前の予備洗浄の機能を有し、下流側の吸引装置４４は、ディスクブラシ４２によって掻き出された異物４５を吸引除去する機能を有する。よって、吸引装置４４は、少なくとも下流側に設置すればよい。 The arrangement position of the suction device 44 is not limited to the two locations on the upstream side and the downstream side, and may be installed at least on the downstream side. The upstream suction device 44 has a function of pre-cleaning before the foreign matter is scraped by the disc brush 42, and the downstream suction device 44 has a function of sucking and removing the foreign matter 45 scraped by the disc brush 42. Therefore, the suction device 44 may be installed at least on the downstream side.
　筐体６２の長さＬ１は、合紙１１の幅Ｗよりも長く、かつ、合紙１１の幅全域を覆うように合紙１１に対し、離間して配置される。筐体６２の合紙対向面には、吸引口６６が筐体６２の長手方向に沿って複数本又は１本のスリットとして設けられている。よって、ディスクブラシ４２が回転駆動され、かつ吸引ポンプ６４が駆動されることにより、ディスクブラシ４２によって掻き出された異物４５が吸引口６６から筐体６２を介して吸引ポンプ６４によって吸引除去される。 The length L1 of the housing 62 is longer than the width W of the interleaf paper 11 and is disposed away from the interleaf paper 11 so as to cover the entire width of the interleaf paper 11. A suction port 66 is provided as a plurality of slits or one slit along the longitudinal direction of the casing 62 on the surface of the casing 62 facing the interleaf. Accordingly, when the disc brush 42 is driven to rotate and the suction pump 64 is driven, the foreign matter 45 scraped by the disc brush 42 is sucked and removed from the suction port 66 through the housing 62 by the suction pump 64. .
　なお、吸引手段の形態は、吸引装置４４に限定されるものではなく、ディスクブラシ４２によって掻き出された異物４５を、合紙１１に再付着させることなく吸引除去できる形態であれば適用できる。例えば、ディスクブラシ４２に吸引口を設け、この吸引口と吸引ポンプ６４とをロータリージョイントを介して接続し、ディスクブラシ４２にて掻き出された異物４５をディスクブラシ４２の吸引口から吸引除去する形態でもよい。また、全てのディスクブラシ４２を筐体で覆い、この筐体の吸引口から吸引除去する形態でもよい。 It should be noted that the form of the suction means is not limited to the suction device 44, and any form that can suck and remove the foreign matter 45 scraped by the disc brush 42 without reattaching to the interleaf paper 11 can be applied. For example, the disk brush 42 is provided with a suction port, and the suction port and the suction pump 64 are connected via a rotary joint, and the foreign matter 45 scraped by the disk brush 42 is sucked and removed from the suction port of the disk brush 42. Form may be sufficient. Alternatively, all the disk brushes 42 may be covered with a casing and sucked and removed from the suction port of the casing.
　〈クリーニング装置４０の作用〉
　合紙供給装置４６及び合紙巻取装置４８を駆動して、合紙１１を合紙走行経路５０に沿って、所定のテンションを付加させた状態で走行させる。 <Operation of Cleaning Device 40>
The slip sheet supply device 46 and the slip sheet take-up device 48 are driven to cause the slip sheet 11 to travel along the slip sheet travel path 50 with a predetermined tension applied.
　合紙１１の走行が開始されると、ディスクブラシ４２及び吸引装置４４を駆動する。 When the slip sheet 11 starts running, the disk brush 42 and the suction device 44 are driven.
　これにより、合紙１１の表裏面が回転するディスクブラシ４２に擦られて、表裏面に付着した異物４５がディスクブラシ４２によって掻き出され、掻き出された異物４５は吸引装置４４によって合紙１１から吸引除去される。そして、異物４５が除去されたクリーニング後の合紙１１が合紙巻取装置４８に巻き取られる。 As a result, the front and back surfaces of the slip sheet 11 are rubbed against the rotating disk brush 42, and the foreign matter 45 attached to the front and back surfaces is scraped by the disc brush 42, and the scraped foreign matter 45 is sucked by the suction device 44. Is removed by suction. Then, the cleaned interleaf paper 11 from which the foreign matter 45 has been removed is taken up by the interleaf paper winding device 48.
　したがって、実施形態のクリーニング装置４０によれば、合紙１１のクリーニングを自動化することができる。また、クリーニング後の合紙１１をロール状で保管することができる。 Therefore, according to the cleaning device 40 of the embodiment, the cleaning of the slip sheet 11 can be automated. Further, the interleaving paper 11 after cleaning can be stored in a roll shape.
　この後、ガラス板Ｇ用の合紙１０として使用する場合には、クリーニング後のロールから帯状の合紙１１を引き出し、帯状の合紙１１をカッターによってガラス板のサイズに対応したサイズに切り出す。よって、図１に示した積層体１２では、合紙１０からガラス板Ｇに付着する異物４５の付着量を低減できる。 Thereafter, when using as the slip sheet 10 for the glass sheet G, the strip-shaped slip sheet 11 is pulled out from the roll after cleaning, and the strip-shaped slip sheet 11 is cut out to a size corresponding to the size of the glass sheet by a cutter. Therefore, in the laminated body 12 shown in FIG. 1, the adhesion amount of the foreign material 45 adhering to the glass plate G from the interleaf paper 10 can be reduced.
　これにより、合紙１０からの異物４５の付着量を低減した積層体１２、及びこの積層体１２をパレット１４に梱包してなる梱包体１６を提供できる。 Thereby, it is possible to provide the laminated body 12 in which the amount of the foreign matter 45 from the interleaf paper 10 is reduced, and the packaging body 16 formed by packing the laminated body 12 on the pallet 14.

　クリーニング装置７０は、図３に示したクリーニング装置４０に対し、ディスクブラシ４２に代えてロールブラシ７２を使用した点が相違し、他の構成部材は同一である。よって、同一の構成部材については同一の符号を付し、その説明は省略する。 The cleaning device 70 differs from the cleaning device 40 shown in FIG. 3 in that a roll brush 72 is used instead of the disc brush 42, and the other components are the same. Therefore, the same components are denoted by the same reference numerals, and the description thereof is omitted.
　ロールブラシ７２は、その回転軸の表面に複数本の軟性毛材が植設されて構成され、軟性毛材の先端部が所定の圧力（面圧）を持って合紙１１の表裏面に当接される。また、モータ７４からの動力が伝達されて矢印Ｄの如く回転される。これにより、合紙１１の表裏面に存在する異物４５が掻き出される。 The roll brush 72 has a structure in which a plurality of soft bristle materials are implanted on the surface of the rotating shaft, and the tip of the soft bristle material has a predetermined pressure (surface pressure) applied to the front and back surfaces of the interleaf paper 11. Touched. Further, the power from the motor 74 is transmitted and rotated as indicated by the arrow D. As a result, the foreign matter 45 existing on the front and back surfaces of the slip sheet 11 is scraped off.
　ロールブラシ７２の回転軸Ｐ２は、合紙１１の主面に対して平行方向に設定されるが、平行方向とは厳密な垂直方向を意味するものではなく、ロールブラシ７２によるクリーニング性能を担保できる許容範囲において傾斜した角度を含むものである。 The rotation axis P2 of the roll brush 72 is set in a direction parallel to the main surface of the interleaf paper 11, but the parallel direction does not mean a strict vertical direction, and the cleaning performance by the roll brush 72 can be ensured. It includes an angle that is inclined within an allowable range.
　ロールブラシ７２は、合紙１１の矢印Ｂで示す送り出し方向に対し、直交する方向に配置され、かつ、ロールブラシ７２の長さＬ２は、合紙１１の幅Ｗよりも長く、かつ、合紙１１の幅全域を覆うよう配置される。 The roll brush 72 is arranged in a direction orthogonal to the feeding direction indicated by the arrow B of the slip sheet 11, and the length L2 of the roll brush 72 is longer than the width W of the slip sheet 11, and the slip sheet 11 is arranged so as to cover the entire width.
