Description

本発明は、ガラス基板を積層梱包する際に用いる合紙等の紙葉類を切断する装置に関する。   The present invention relates to an apparatus for cutting paper sheets such as slip sheets used when stacking and packing glass substrates.

液晶ディスプレイ、プラズマディスプレイなどのフラットパネルディスプレイ用ガラス基板は、近年において大型化および薄型化が進められている。例えば、第８世代、Ｇ８と称されているガラス基板になると、ガラス基板のサイズは２５００ｍｍ×２２００ｍｍ、厚さ０．７ｍｍ程度とされる。
この種フラットパネルディスプレイ用のガラス基板を搬送するには、合紙を介しガラス基板を縦置きして複数枚積層し梱包容器に収容するか、合紙を介し積層したガラス基板を横置きに積層した状態で梱包容器に収容し、梱包容器に収容した状態で輸送機械により搬送している。
ガラス基板の間に介在させる合紙は、通常、ロール装置に巻き付けてロール状に収容されているので、このロールから必要な長さの合紙をコンベア等の搬送路上に引き出し、搬送路上で裁断して１枚の合紙とされ、コンベア上を流れてくるガラス基板の上に載置する形でガラス基板に重ねられる。
規模の大きなガラス基板用の梱包容器では１００〜２００枚ものガラス基板を梱包容器に収容することが知られている。 In recent years, glass substrates for flat panel displays such as liquid crystal displays and plasma displays have been increased in size and thickness. For example, in the case of a glass substrate called 8th generation, G8, the size of the glass substrate is about 2500 mm × 2200 mm and the thickness is about 0.7 mm.
To transport a glass substrate for this kind of flat panel display, a plurality of glass substrates are stacked vertically through a slip sheet and stacked in a packaging container, or a glass substrate stacked through a slip sheet is stacked horizontally. It is housed in a packaging container in a state of being transported, and is transported by a transport machine in a state of being housed in a packaging container.
Since the interleaving paper interposed between the glass substrates is usually wound around a roll device and accommodated in a roll shape, the required length of interleaving paper is drawn out on a conveying path such as a conveyor and cut on the conveying path. Thus, a single slip sheet is formed, and is stacked on the glass substrate in a form of being placed on the glass substrate flowing on the conveyor.
In a packaging container for a large-scale glass substrate, it is known that 100 to 200 glass substrates are accommodated in the packaging container.

ところで、ロール紙を切断する装置として、以下の特許文献１に記載のように、ロール状記録紙から引き出された記録紙部分を引き出し方向と直交する方向にシート状にカットするカッタ刃を備えたロール紙切断装置が知られている。この装置は、記録紙部分の移動方向と同じ方向に同じ速度でカッタユニットを移動させながらロール状記録紙を引き出し方向と直交する方向に切断できる装置として構成されている。
また、紙葉類を切断する他の例の装置として、以下の特許文献２に記載のようにギロチン式の平板状切断刃を上下移動自在に設けた構造を有し、紙葉類を紙載台上に複数枚積み重ねてセットし、その所定箇所を切断刃で裁断する構成の裁断装置が知られている。 By the way, as an apparatus for cutting roll paper, as described in Patent Document 1 below, a cutter blade that cuts a recording paper portion drawn from a roll-like recording paper into a sheet shape in a direction perpendicular to the drawing direction is provided. A roll paper cutting device is known. This apparatus is configured as an apparatus capable of cutting a roll-shaped recording sheet in a direction perpendicular to the pulling-out direction while moving the cutter unit at the same speed in the same direction as the moving direction of the recording sheet portion.
Further, as another example apparatus for cutting paper sheets, a guillotine type flat cutting blade is provided so as to be movable up and down as described in Patent Document 2 below. A cutting device having a configuration in which a plurality of sheets are stacked and set on a table and a predetermined portion thereof is cut with a cutting blade is known.

特開平５−２２８８９３号公報JP-A-5-228893 特開２００９−１７２７４３号公報JP 2009-172743 A

前述のフラットパネルディスプレイ用の合紙は長さ、幅、共に極めて大きく、切断する距離も長いので特許文献１に記載の装置のようにカッタユニットを記録紙の移動方向に移動させる構造は採用できない問題がある。
そこで、従来では、図３、図４に示す板状のギロチン式の切断刃を上下方向に移動自在に設けた構造であって、切断刃を上刃１００と下刃１０１の上下２枚構造とした切断装置１０２が知られている。 The above-described flat panel display slip sheet is extremely large in both length and width, and has a long cutting distance. Therefore, the structure in which the cutter unit is moved in the moving direction of the recording paper as in the apparatus described in Patent Document 1 cannot be adopted. There's a problem.
Therefore, in the prior art, a plate-shaped guillotine cutting blade shown in FIGS. 3 and 4 is provided so as to be movable in the vertical direction, and the cutting blade is composed of an upper blade 100 and a lower blade 101. A known cutting device 102 is known.

この切断装置１０２は、水平に配置した供給ロール１０３に合紙をロール巻きしておき、この供給ロール１０３に押し付けた駆動ロール１０４を回転させることで供給ロール１０３から水平方向に合紙を引き出すことができる構成とされている。供給ロール１０３の近傍に水平方向に合紙を搬送できる搬送路１０５が設けられ、この搬送路１０５の途中にギロチン方式の上刃１００と下刃１０１が設けられている。上刃１００と下刃１０１は、図４に示すように上下に対向配置され、上刃１００が板状のベース１０６に取り付けられるとともに、ベース１０６が下向きのエアーシリンダ装置１０７のシリンダロッド１０８の下端部にコネクター部材１０９を介し取り付けられ、シリンダロッド１０８の上下移動とともに上刃１００が上下移動する。   The cutting device 102 rolls a slip sheet around a supply roll 103 arranged horizontally, and pulls the slip sheet from the supply roll 103 in a horizontal direction by rotating the drive roll 104 pressed against the supply roll 103. It can be configured. A conveyance path 105 capable of conveying the slip sheet in the horizontal direction is provided in the vicinity of the supply roll 103, and a guillotine upper blade 100 and a lower blade 101 are provided in the middle of the conveyance path 105. As shown in FIG. 4, the upper blade 100 and the lower blade 101 are vertically opposed to each other, the upper blade 100 is attached to a plate-like base 106, and the lower end of the cylinder rod 108 of the air cylinder device 107 with the base 106 facing downward. The upper blade 100 moves up and down as the cylinder rod 108 moves up and down.

図３、図４に示す従来の切断装置１０２において、上刃１００の幅方向一側端部には下向きに短冊状に延出形成された案内板１００ａが設けられ、下刃１０１の幅方向一側端部に案内部１０１ａが形成され、この案内部１０１ａに沿って案内板１００ａが上下方向にスライド移動自在に挿入されている。切断装置１０２において、上刃１００の案内板１００ａを下刃１０１の案内部１０１ａに挿通することで上刃１００と下刃１０１の互いの刃先部分が位置ずれしないように上下動の軌跡が制限されており、上刃１００の刃先と下刃１０１の刃先の位置ずれが抑制されている。なお、上刃１００の刃先部１００ｂは図４に示すようにその幅方向一側端部から他側端部にかけて傾斜する刃先部とされ、案内板１００ａを形成した側の刃先部が反対側の刃先部よりも下側に位置するように傾斜されている。
図３、図４に示す切断装置１０２において、搬送路１０５の横に金属製の堅牢なフレーム部材１１０が立設され、その上端部にシリンダ装置１０７が設けられ、該シリンダ装置１０７のシリンダロッド１０８の下端部に厚い金属製のベース部材１１１が設けられ、このベース部材１１１を介し板状の上刃１００が支持されている。
切断装置１０２において上刃１００を厚い金属製のベース部材１１１に取り付けることで刃先の位置ずれを抑制しており、上刃１００と下刃１０１の間に挟んだ合紙１１２を位置ズレすることなく繰り返し切断することができる。 In the conventional cutting device 102 shown in FIGS. 3 and 4, a guide plate 100 a that extends downward in a strip shape is provided at one end in the width direction of the upper blade 100. A guide portion 101a is formed at the side end, and a guide plate 100a is inserted along the guide portion 101a so as to be slidable in the vertical direction. In the cutting device 102, the trajectory of the vertical movement is limited by inserting the guide plate 100 a of the upper blade 100 into the guide portion 101 a of the lower blade 101 so that the cutting edge portions of the upper blade 100 and the lower blade 101 are not displaced from each other. Therefore, the positional deviation between the cutting edge of the upper blade 100 and the cutting edge of the lower blade 101 is suppressed. As shown in FIG. 4, the blade edge portion 100b of the upper blade 100 is a blade edge portion that is inclined from one end portion in the width direction to the other end portion, and the blade edge portion on the side where the guide plate 100a is formed is on the opposite side. It is inclined so as to be located below the blade edge part.
In the cutting device 102 shown in FIGS. 3 and 4, a solid metal frame member 110 is erected on the side of the conveyance path 105, and a cylinder device 107 is provided at an upper end portion thereof, and a cylinder rod 108 of the cylinder device 107 is provided. A thick metal base member 111 is provided at the lower end of the plate, and the plate-like upper blade 100 is supported via the base member 111.
In the cutting apparatus 102, the upper blade 100 is attached to a thick metal base member 111 to suppress the positional deviation of the blade edge, and the slip sheet 112 sandwiched between the upper blade 100 and the lower blade 101 is not displaced. Can be cut repeatedly.

しかし、図３、図４に示す堅牢な構造の切断装置１０２であっても、上述のフラットパネルディスプレイ用ガラス基板のような大型のガラス基板対応の合紙１１２を繰り返し切断している間に上刃１００と下刃１０１の位置ずれが生じることがあった。
例えば、ガラス基板は更なる大型化がなされており、第１０世代、Ｇ１０と称される大型のガラス基板は２８８０ｍｍ×３１３０ｍｍの大きさに形成される。これに伴い、上述の上刃１００も大型化されてきており、例えば、厚さ１６ｍｍ、幅（長さ）３ｍ以上の大型の上刃１００も登場している。
このため、上刃１００を取り付けたベース部材１１１を金属製の剛性が高い厚板構造としても、剛性（ねじれ剛性、曲げ剛性）が十分ではなくなる問題が生じている。
例えば、合紙の切断を繰り返すうちに、ベース部材１１１に歪みが生じ、上刃１００と下刃１１１との噛み合わせにずれが生じ、切れ味が悪くなる、という問題が生じている。
また、合紙の厚さは約０．０８ｍｍと極めて薄いため、上刃１００と下刃１０１とがロール紙１１２を切断する際の刃先間隔について０〜０．０１ｍｍ程度の極めて小さな間隔を維持する必要があるが、上述したように上刃１００の大型化に伴ない、間隔の正確な維持は困難になってきている。 However, even the cutting device 102 having a robust structure shown in FIGS. 3 and 4 is in the process of repeatedly cutting a large glass substrate compatible paper 112 such as the glass substrate for flat panel display described above. The positional deviation between the blade 100 and the lower blade 101 may occur.
For example, the glass substrate has been further increased in size, and a large glass substrate called 10th generation, G10, is formed to have a size of 2880 mm × 3130 mm. Along with this, the above-described upper blade 100 has also been increased in size. For example, a large upper blade 100 having a thickness of 16 mm and a width (length) of 3 m or more has appeared.
For this reason, even if the base member 111 to which the upper blade 100 is attached has a thick plate structure made of metal with high rigidity, there is a problem that rigidity (torsional rigidity, bending rigidity) is not sufficient.
For example, while the cutting of the slip sheet is repeated, the base member 111 is distorted, the meshing between the upper blade 100 and the lower blade 111 is shifted, and the sharpness is deteriorated.
Further, since the thickness of the interleaf paper is as extremely thin as about 0.08 mm, an extremely small interval of about 0 to 0.01 mm is maintained with respect to the blade edge interval when the upper blade 100 and the lower blade 101 cut the roll paper 112. Although it is necessary, as the upper blade 100 becomes larger as described above, it is difficult to accurately maintain the interval.

これらの背景に基づき、本発明者は、大型のガラス基板対応の合紙などの紙葉類を切断する装置において、切断刃を支持するベースの剛性を高め、多数の紙葉類を切断する場合であっても切断刃の位置ずれが生じないようにして切断精度を高めた紙葉類の切断装置の提供を目的とする。   Based on these backgrounds, the present inventor increases the rigidity of the base that supports the cutting blade and cuts a large number of paper sheets in an apparatus that cuts paper sheets such as slip sheets for large glass substrates. Even so, it is an object of the present invention to provide a paper sheet cutting apparatus with improved cutting accuracy so that the position of the cutting blade does not shift.

本発明は、供給ロールから引き出したロール紙をその幅方向に沿って切断する紙葉類の切断装置であって、引き出したロール紙を案内する搬送路と、該搬送路に沿って移動するロール紙に対しその厚さ方向両側にロール紙を挟むように配置され前記ロール紙より幅の広い一対の板状の切断刃と、対向する一対の側壁およびこれら側壁を接続する接続壁とからなる中空構造をなし、前記切断刃の一方を取り付ける取付面を前記側壁の表面に有し、前記ロール紙の厚さ方向に移動自在に設けられ、前記取付面に切断刃を取り付けたベースと、該ベースを前記ロール紙の厚さ方向に移動させて前記ベースに備えた切断刃を前記他方の切断刃の刃先前方位置のロール紙に対し押し付けて前記他方の切断刃とともにロール紙を切断するための駆動機構とを備えたことを特徴とする。   The present invention is a paper sheet cutting device for cutting a roll paper drawn from a supply roll along the width direction thereof, a conveyance path for guiding the drawn roll paper, and a roll moving along the conveyance path A hollow composed of a pair of plate-like cutting blades arranged so as to sandwich the roll paper on both sides in the thickness direction with respect to the paper, wider than the roll paper, a pair of opposing side walls, and a connection wall connecting these side walls A base having a structure and having a mounting surface for mounting one of the cutting blades on the surface of the side wall, provided movably in the thickness direction of the roll paper, and having the cutting blade attached to the mounting surface; For cutting the roll paper together with the other cutting blade by moving the roll blade in the thickness direction of the roll paper and pressing the cutting blade provided on the base against the roll paper at the front edge position of the other cutting blade Mechanism and Characterized by comprising.

本発明において、前記ベースの側壁の一部に係止部が形成され、該側壁の側方に前記係止部を支持して前記ベースの移動を阻止するストップ機構が設けられた紙葉類の切断装置とすることができる。 In the present invention, the base is formed into a rectangular tubular shape from a pair of side walls facing each other and a connection wall connecting both side walls, and a paper sheet cutting apparatus in which a reinforcing material is installed between the facing side walls. Can do.
In the present invention, there is provided a paper sheet in which a locking portion is formed on a part of the side wall of the base, and a stop mechanism is provided on a side of the side wall to support the locking portion and prevent the base from moving. It can be a cutting device.

本発明は、前記搬送路の近傍に支柱部が立設され、該支柱部に前記搬送路に対し接近離間自在にロッドを配置した直動装置が取り付けられ、前記ロッドの先端部に前記ベースが取り付けられて前記ベースが搬送路に対し接近離間自在に支持された構成にできる。
本発明は、前記ロール紙の厚さ方向に対し移動自在に設けられた一方の切断刃の刃先部より基端側に、前記他方の切断刃の刃先部との干渉を避けるための凹型の逃げ部が形成された構成にできる。 In the present invention, a support column is provided upright in the vicinity of the conveyance path, and a linear motion device in which a rod is disposed on the support column so as to be able to approach and separate from the conveyance path is attached. The base is attached to the tip of the rod. It is possible to adopt a configuration in which the base is attached and supported so as to be close to and away from the conveyance path.
The present invention provides a concave relief for avoiding interference with the cutting edge portion of the other cutting blade on the proximal side from the cutting edge portion of one cutting blade provided movably in the thickness direction of the roll paper. The part can be formed.

本発明は、前記ベースに複数の被検知体が取り付けられ、前記ベースの近傍に前記被検知体の移動を検知して移動自在とされた前記切断刃の位置を検出するセンサが設けられた構成にできる。 In the present invention, the transport path is a transport path for horizontally transporting the roll paper, the one cutting blade is an upper blade, the other cutting blade is a lower blade, and the lower blade is the transport path. The upper blade is fixed to the mounting surface of the base so as to be movable up and down together with the base with the blade tip portion facing downward, and the inner surface of the upper blade on the lower blade side interferes with the lower blade. It is possible to make a configuration in which an escape portion for avoiding the above is formed.
In the present invention, a plurality of detected bodies are attached to the base, and a sensor is provided in the vicinity of the base for detecting the position of the cutting blade that is movable by detecting the movement of the detected body. Can be.

本発明によれば、側壁の取付面に切断刃を取り付けたベースを側壁と接続壁とからなる中空構造として、従来構造の板状のベースより剛性を向上させたベースとしたので、多数の紙葉類を切断した場合であってもベースが歪むおそれが少なく、切断精度の低下を引き起こすことなく高精度のまま、切れ味の良い切断ができる紙葉類の切断装置を提供できる。
また、本発明の切断装置によれば、フラットパネルディスプレイ用ガラス基板に挟む梱包用の合紙のように、縦横数ｍに及ぶ巨大な合紙などのような大きな紙葉類を多数枚切断する処理を行ったとしても、ベースの歪みを少なくすることが可能となり、切れ味の低下が生じない、高精度のまま切断のできる紙葉類の切断装置を提供できる。 According to the present invention, since the base having the cutting blade attached to the attachment surface of the side wall has a hollow structure composed of the side wall and the connection wall, the base has a higher rigidity than the plate-like base of the conventional structure. Even when the leaves are cut, the base is less likely to be distorted, and it is possible to provide a paper sheet cutting device capable of cutting with high sharpness while maintaining high accuracy without causing a reduction in cutting accuracy.
Further, according to the cutting apparatus of the present invention, a large number of large paper sheets such as huge slip sheets having a length and width of several m are cut like packing slip sheets sandwiched between flat panel display glass substrates. Even if the processing is performed, it is possible to reduce the distortion of the base, and it is possible to provide a paper sheet cutting device capable of cutting with high accuracy without causing sharpness deterioration.

本発明の切断装置において、ベースの側壁に設けた係止部をストップ機構で係止してベースの移動を阻止するならば、切断刃の移動を阻止した状態で紙葉類や搬送路あるいは付帯設備等のメンテナンスを安全に行うことができ、メンテナンス作業時の安全性を向上できる効果がある。
本発明の切断装置において、搬送路を横断するように移動する一方の切断刃の刃先部より基端側に、他方の切断刃の刃先部の逃げ部を設けたので、一方の切断刃と他方の切断刃の接触による摩耗を抑制できる効果がある。また、逃げ部を設けることにより一方の切断刃と他方の切断刃の摩耗粉の発生を抑制できるので、切断対象の紙葉類を摩耗粉で汚してしまうことがない。 In the cutting apparatus of the present invention, if the locking portion provided on the side wall of the base is locked by the stop mechanism to prevent the movement of the base, the paper sheet, the conveyance path, or the accessory in a state where the movement of the cutting blade is blocked. The maintenance of facilities and the like can be performed safely, and the safety during maintenance work can be improved.

An interleaf paper 9 as one kind of paper sheets is wound around the supply roll 2 in a roll shape, and a drive roll 8 above the roll body formed by the interleaf paper 9 is pressed with a predetermined tension. . By rotating the drive roll 8 while pressing the drive roll 8 against the supply roll 2, the slip sheet 9 wound around the supply roll 2 can be fed out to the necessary length conveyance path 3 side. The supply roll 2 and the drive roll 8 are supported by a bearing (not shown) and are rotatably supported. In FIG. 1, the bearing portions and the support mechanism of the supply roll 2 and the drive roll 8 are not shown. Only the position of each roll is shown in a simplified manner.
On the side of the supply roll 2, transport tables 12, 13, 15 supported by the gantry 10, 11, etc. are horizontally installed, and these transport tables 12, 13, 15 are horizontally positioned on the side of the supply roll 2. A conveyance path 3 extending in the direction of is formed.

前記搬送テーブル１２、１３は搬送路３に沿って所定の間隔をあけて配置され、搬送テーブル１２、１３の間に、架台１０に支持された下刃６が水平に固定されている。この下刃６は搬送路３の幅方向に細長い水平向きの平板状の本体部６ａを有し、搬送路３の下流側に位置する本体部６ａの一側端縁上部に刃先部６ｂが形成されている。この刃先部６ｂは、一例として、図２（ｃ）に示すように鋼材からなる本体部６ａの一側端縁に超硬合金チップや刃物合金チップを固定し構成されている。   The conveyance tables 12 and 13 are arranged at a predetermined interval along the conveyance path 3, and the lower blade 6 supported by the gantry 10 is horizontally fixed between the conveyance tables 12 and 13. The lower blade 6 has a horizontally-oriented flat plate-like main body portion 6a that is elongated in the width direction of the conveyance path 3, and a blade edge portion 6b is formed at the upper end of one side edge of the main body portion 6a that is located on the downstream side of the conveyance path 3. Has been. As an example, the cutting edge portion 6b is configured by fixing a cemented carbide tip or a blade alloy tip to one side edge of a main body portion 6a made of steel as shown in FIG. 2 (c).

下刃６の刃先部６ｂの先端位置より若干搬送路３に沿って下流側であって、搬送テーブル１３との間に上刃５を導入するための隙間Ｄが形成され、この隙間Ｄの上方にほぼ垂直向きに上刃５が上下に移動自在に設けられている。この上刃５は、搬送路３の幅方向に細長い上下方向向きの板状の本体部５ａからなり、この本体部５ａの下端縁に刃先部５ｂが形成されている。この上刃５の幅方向一側端縁部には図４を基に先に説明した案内板１００ａと同等構造の案内板５ｃが下向きに突出形成されている。また、下刃６の幅方向端縁部にも図４を基に先に説明した案内部１０１ａと同等形状の案内部（図示略）が形成されていて、下刃６の案内部に沿って上刃５の案内板５ｃを挿通することで上刃６の上下移動の軌跡を制限し、下刃６に対して上刃５を位置ズレすることなく、正確に移動できるように上刃５の上下動が規制されている。なお、本実施形態の上刃６において先に説明した上刃１００と同様、上刃５の刃先部５ｂは傾斜されていて、案内板５ｃを設けた側の刃先部５ｂの位置がその反対側の端部の位置よりも低い位置となるように傾斜されている。   A gap D for introducing the upper blade 5 is formed between the lower edge 6 and the conveying table 13 slightly downstream from the tip position of the cutting edge 6b of the lower blade 6 and above the gap D. The upper blade 5 is provided so as to be movable vertically in a substantially vertical direction. The upper blade 5 is composed of a plate-like main body portion 5a that is elongated in the width direction of the conveyance path 3 and is oriented in the vertical direction. A blade edge portion 5b is formed at the lower edge of the main body portion 5a. A guide plate 5c having a structure equivalent to that of the guide plate 100a described above with reference to FIG. 4 is formed to protrude downward on one side edge of the upper blade 5 in the width direction. Further, a guide portion (not shown) having the same shape as the guide portion 101a described above with reference to FIG. 4 is formed at the edge portion in the width direction of the lower blade 6, and along the guide portion of the lower blade 6. By inserting the guide plate 5c of the upper blade 5, the trajectory of the vertical movement of the upper blade 6 is limited, and the upper blade 5 can be moved accurately without being displaced with respect to the lower blade 6. Vertical movement is restricted. In the upper blade 6 of the present embodiment, like the upper blade 100 described above, the blade edge portion 5b of the upper blade 5 is inclined, and the position of the blade edge portion 5b on the side where the guide plate 5c is provided is the opposite side. It is inclined so as to be at a position lower than the position of the end portion.

前記上刃５の刃先部５ｂと下刃６の刃先部６ｂは、上刃５の刃先部５ｂを下降させて下刃６の刃先部６ｂと同等高さとした場合、若干の間隙（０．０１ｍｍ以下）をあけて対向するように配置されている。即ち、下刃６の刃先部６ｂの若干前方位置（搬送路３に沿って若干下流側の位置）を上刃５の刃先部５ｂが鉛直方向に上下移動できるように上刃５が設置されている。
より詳細には、図２（ａ）（ｂ）に示すように、水平に設置されている下刃６において図２（ａ）の右端縁の上面側（搬送路３の下流側端縁の上面側）に超硬合金チップあるいは刃物合金チップを固定して刃先部６ｂが構成されている。また、垂直に設置されている上刃５の本体部５ａにおいて下刃６側（下端縁左側）の端縁部に刃物金属あるいは超硬合金などからなるチップを固定して刃先部５ｂが構成されている。上刃５において刃先部５ｂを形成した位置の若干上側の部分（基端側部分）に本体部５ａを部分的に薄くするように凹溝型の逃げ部５ｃが形成されている。この逃げ部５ｃは、図２（ｂ）に示すように上刃５を下降させて下刃６の刃先部６ｂの前方を通過させた場合、下刃６の刃先部６ｂが上刃５の本体部５ａと擦れないように、本体部５ａを部分的に摩耗することを防止するために形成されている。従って、逃げ部５ｃの上端位置５ｃ１は、上刃５が下端位置まで移動した場合であっても下刃６の刃先部６ｂが逃げ部５ｃの内側に存在するように形成されていることが好ましく、逃げ部５ｃの下端部５ｃ２は刃先部５ｂの若干上側に形成されていることが好ましい。 The cutting edge portion 5b of the upper blade 5 and the cutting edge portion 6b of the lower blade 6 have a slight gap (0.01 mm) when the cutting edge portion 5b of the upper blade 5 is lowered to the same height as the cutting edge portion 6b of the lower blade 6. Are arranged so as to face each other. That is, the upper blade 5 is installed so that the blade edge portion 5b of the upper blade 5 can move vertically in a slightly forward position of the blade edge portion 6b of the lower blade 6 (position slightly downstream along the transport path 3). Yes.
More specifically, as shown in FIGS. 2 (a) and 2 (b), in the lower blade 6 installed horizontally, the upper surface side of the right edge in FIG. 2 (a) (the upper surface of the downstream edge of the conveyance path 3). A cutting edge portion 6b is configured by fixing a cemented carbide chip or a blade alloy chip to the side). Further, in the main body portion 5a of the upper blade 5 installed vertically, a tip made of a blade metal or cemented carbide is fixed to the edge portion of the lower blade 6 side (lower edge left side) to form the blade edge portion 5b. ing. A concave groove type relief portion 5c is formed in a portion slightly above the position (base end side portion) where the blade edge portion 5b is formed in the upper blade 5 so as to partially thin the main body portion 5a. As shown in FIG. 2 (b), the escape portion 5 c is configured such that when the upper blade 5 is lowered and passed in front of the blade edge portion 6 b of the lower blade 6, the blade edge portion 6 b of the lower blade 6 is the main body of the upper blade 5. It is formed to prevent the main body portion 5a from being partially worn so as not to rub against the portion 5a. Thus, the upper end position 5c 1 of the relief portion 5c is that the upper knife 5 is cutting edge 6b of the lower blade 6 even when moving are formed so as to present inside the relief portion 5c to the lower end position preferably, the lower end portion 5c 2 of the relief portion 5c is preferably formed slightly above the cutting edge 5b.

前記下刃６の上方側であって、上刃５の側面側には、鋼材からなる中空構造のベース本体１７を主体として構成されたベース１９が設けられている。前記ベース本体１７は、上刃５側に取付面１７ａを向けた一側の側壁１７Ａと、この側壁１７Ａに距離をあけて対向配置された他側の側壁１７Ｂと、これら側壁１７Ａ、１７Ｂの上端部に連続一体化された接続壁（上部壁）１７Ｃと、側壁１７Ａ、１７Ｂの下端部に連続一体化された接続壁（底部壁）１７Ｄとからなる中空構造（略矩形管構造）とされている。また、ベース本体１７の内底部側に側壁１７Ａ、１７Ｂを貫通するようにパイプ状の補強材１８が架設されている。この補強材１８は、ベース本体１７の幅方向（搬送路３の幅方向）に１０数本〜１０数本程度、等間隔に溶接により架設され、補強材１８によりベース本体１７が補強され、歪みが生じないように強化されている。
なお、補強材１８の設置本数はベース本体１７の横幅の大小に応じて必要数設けることができる。例えば、Ｇ１０クラス（第１０世代クラス）の大きさのガラス基板に対応するための合紙の場合、例えば、幅３ｍを超えるベース本体１７の大きさとなるので、その場合は２０数本程度、補強材１８を設けることができる。
また、ベース本体１７の形状は側面視矩形管に限らず、横断面井桁状や田型、♯型等の中空構造でも良く、対向する側壁とそれらを一体化する接続壁を備えた剛性の高い中空形状であれば任意の形状でよい。また、管状に限らず、ボックス型であってもよい。 On the upper side of the lower blade 6 and on the side surface of the upper blade 5, a base 19 composed mainly of a base body 17 having a hollow structure made of steel is provided. The base body 17 includes one side wall 17A with the mounting surface 17a facing the upper blade 5 side, the other side wall 17B disposed opposite to the side wall 17A at a distance, and upper ends of the side walls 17A and 17B. A hollow structure (substantially rectangular tube structure) comprising a connection wall (upper wall) 17C continuously integrated with the portion and a connection wall (bottom wall) 17D continuously integrated with the lower ends of the side walls 17A and 17B. Yes. A pipe-shaped reinforcing member 18 is installed on the inner bottom side of the base body 17 so as to penetrate the side walls 17A and 17B. The reinforcing member 18 is installed by welding at equal intervals in the width direction of the base main body 17 (width direction of the conveyance path 3), and the base main body 17 is reinforced by the reinforcing member 18 to be distorted. It has been strengthened so as not to occur.
The number of reinforcing members 18 can be set according to the width of the base body 17 as required. For example, in the case of a slip sheet for accommodating a glass substrate having a size of G10 class (10th generation class), for example, the size of the base body 17 exceeds a width of 3 m. A material 18 can be provided.
The shape of the base body 17 is not limited to a rectangular tube when viewed from the side, and may be a hollow structure such as a cross-beam shape, a paddle shape, or a # shape, and has a highly rigid structure including opposing side walls and connection walls that integrate them. Any shape can be used as long as it is hollow. Moreover, it is not limited to a tubular shape but may be a box type.

前記一側の側壁１７Ａの表面はフライス加工などにより平滑な平面状に加工されていて、この加工面が取付面１７ａとされている。この取付面１７ａの下部側に上下３本の対になる取付ボルト（固定具）２０、２１、２２により上刃５が鉛直向きに取り付けられている。なお、上刃５をベース本体１７の側壁１７Ａに取り付けるために上刃５と側壁１７Ａを複数の取付ボルト２０、２１、２２が貫通するので、これらのボルト２０、２１、２２が貫通することによりベース本体１７の剛性が低下する分をこれらの補強材１８が補っている。
前記ベース本体１７は搬送路３の幅方向長さに対応するように形成され、図１の例ではコーナ部に若干Ｒを持たせた矩形管として描かれている。 The surface of the side wall 17A on the one side is processed into a smooth flat surface by milling or the like, and this processed surface serves as an attachment surface 17a. The upper blade 5 is vertically attached to the lower side of the mounting surface 17a by three upper and lower mounting bolts (fixing tools) 20, 21, and 22. In order to attach the upper blade 5 to the side wall 17A of the base body 17, a plurality of mounting bolts 20, 21, and 22 penetrate through the upper blade 5 and the side wall 17A, so that these bolts 20, 21, and 22 penetrate. These reinforcing members 18 compensate for the decrease in the rigidity of the base body 17.
The base main body 17 is formed so as to correspond to the length in the width direction of the transport path 3, and in the example of FIG. 1, it is drawn as a rectangular tube having a slightly rounded corner.

ベース本体１７の側壁１７Ａに配置された取付面１７ａに沿って上刃５の上端部が沿わせられ、上刃５の上端部において上部側を貫通する取付ボルト２０と、上刃５の上端部において下部側を貫通する取付ボルト２１と、それらの間に介在されて上刃５を貫通する取付ボルト２２により上刃５がベース本体１７の取付面１７ａの底部側に固定されている。なお、取付ボルト２０、２１、２２は上刃５の幅方向（搬送路３の幅方向）に沿って複数形成されている。図１では上下３つの取付ボルト２０、２１、２２のみが描かれているが、図１の紙面垂直方向、即ち、上刃５の幅方向に複数、例えば、数１０個程度の取付ボルト２０、２１、２２が設けられている。   An upper end of the upper blade 5 is provided along the mounting surface 17 a disposed on the side wall 17 </ b> A of the base body 17, and the upper end of the upper blade 5 is attached to the mounting bolt 20 penetrating the upper side of the upper blade 5. The upper blade 5 is fixed to the bottom side of the mounting surface 17a of the base body 17 by means of a mounting bolt 21 penetrating the lower side and a mounting bolt 22 interposed between them and penetrating the upper blade 5. A plurality of mounting bolts 20, 21, and 22 are formed along the width direction of the upper blade 5 (width direction of the transport path 3). In FIG. 1, only the three upper and lower mounting bolts 20, 21, and 22 are depicted, but a plurality of, for example, several tens of mounting bolts 20 in the direction perpendicular to the paper surface of FIG. 1, that is, the width direction of the upper blade 5, 21 and 22 are provided.

前記搬送路３の幅方向両側端部の側方にそれぞれ架台１１に支持されて支柱部２５が立設され、これらの支柱部２５の上端部に横方向に延出されたフレーム部材２６を介しエアーシリンダなどのシリンダ装置（伸縮装置）２７が取り付けられている。このシリンダ装置２７は下向きのピストンロッド２７ａを上下方向に移動自在に備えていて、ピストンロッド２７ａの下端部に接合部材２８を介し前述のベース本体１７の接続壁１７Ｃが接合されている。
シリンダ装置２７がピストンロッド２７ａを上下移動させると、この上下移動に連動してベース本体１７を上下移動させることができ、ベース本体１７の取付面１７ａに固定されている上刃５が搬送路３に対し鉛直下向きに向いたまま上下移動する。 Supporting columns 11 are respectively supported on the sides of both ends in the width direction of the conveying path 3 and support columns 25 are erected, and frame members 26 that extend laterally at the upper ends of these support columns 25 are provided. A cylinder device (extension device) 27 such as an air cylinder is attached. The cylinder device 27 is provided with a downward piston rod 27a so as to be movable in the vertical direction, and the connecting wall 17C of the base body 17 is joined to the lower end portion of the piston rod 27a via a joining member 28.
When the cylinder device 27 moves the piston rod 27a up and down, the base body 17 can be moved up and down in conjunction with the up-and-down movement, and the upper blade 5 fixed to the mounting surface 17a of the base body 17 moves the conveyance path 3. Move up and down while facing vertically downward.

前記支柱部２５の上部側に水平方向に移動自在にストップピン３０ａを備えたストップ機構３０が設けられている。このストップ機構３０は小型シリンダ装置あるいはストップピン３０ａを水平方向に移動自在に送る送りねじ機構などを備えた直動型のアクチュエータからなる。ストップ機構３０はストップピン３０ａの先端部を支柱２５に近い位置の側壁１７Ａに向けて水平に取り付けられている。ストップピン３０ａの前方に位置する側壁１７Ａの一部にはストップピン３０ａの先端部と対向する位置にストップピン３０ａの先端部を挿通可能な大きさの係止孔（係止部）１７ｅが形成されている。   A stop mechanism 30 having a stop pin 30a is provided on the upper side of the support column 25 so as to be movable in the horizontal direction. The stop mechanism 30 is composed of a small cylinder device or a direct-acting actuator provided with a feed screw mechanism that feeds a stop pin 30a so as to be movable in the horizontal direction. The stop mechanism 30 is mounted horizontally with the tip of the stop pin 30a facing the side wall 17A at a position close to the column 25. A part of the side wall 17A located in front of the stop pin 30a is formed with a locking hole (locking part) 17e having a size capable of inserting the tip of the stop pin 30a at a position facing the tip of the stop pin 30a. Has been.

前記ストップ機構３０はストップピン３０ａを側壁１７Ａ側に伸長させた場合にその先端部を係止孔１７ｅに挿入してベース本体１７の上下移動を阻止することができ、この挿入状態でベース本体１７の下降を阻止するストッパーとして機能する。
なお、ストップ機構３０について本実施形態においては係止孔１７ｅにストップピン３０ａの先端部を挿入してベース本体１７の下降を阻止した構成としたが、ベース本体１７の下降を阻止できる構造として、ストップ機構の構成は本実施形態の構成に限らない。例えば、係止孔１７ｅの代わりに、係止片や係止突起、係止凹部などをベース本体１７に形成し、これらにストップピン３０ａの先端部を係合させてベース本体１７の下降を阻止できる構造等、種々変更が可能である。 When the stop pin 30a is extended to the side wall 17A, the stop mechanism 30 can prevent the base body 17 from moving up and down by inserting its tip into the locking hole 17e. It functions as a stopper that prevents the descent of the camera.
In the present embodiment, the stop mechanism 30 has a structure in which the tip of the stop pin 30a is inserted into the locking hole 17e to prevent the base body 17 from being lowered. The configuration of the stop mechanism is not limited to the configuration of the present embodiment. For example, instead of the locking hole 17e, locking pieces, locking projections, locking recesses, etc. are formed in the base body 17, and the tip of the stop pin 30a is engaged with these to prevent the base body 17 from descending. Various modifications, such as a possible structure, can be made.

前記支柱部２５に近いベース本体１７の端部側における側壁１７Ａの一部であって、前記取付ボルト２０、２１を設けた位置より若干上方に板状の被検知体１７ｆが突出形成されている。なお、ベース本体１７は上刃５よりも幅が大きく形成され、上刃５の端部よりも側方に突出した部分に他の部品と干渉しないように被検知体１７ｆが取り付けられている。
また、前記支柱部２５の側部に前記被検知体１７ｆの先端位置を検出できる第１のセンサ３１が設けられ、前記支柱部２５において前記第１のセンサ３１の下方に、前記被検知体１７ｆの先端位置を検出できる第２のセンサ３２が設けられている。 A plate-like detected body 17f is formed so as to protrude from a part of the side wall 17A on the end side of the base body 17 close to the support column 25 and slightly above the position where the mounting bolts 20 and 21 are provided. . The base body 17 is formed wider than the upper blade 5, and a detected body 17 f is attached to a portion protruding laterally from the end of the upper blade 5 so as not to interfere with other components.
In addition, a first sensor 31 capable of detecting the tip position of the detected body 17f is provided on a side portion of the support column 25, and the detected object 17f is provided below the first sensor 31 in the support column 25. The 2nd sensor 32 which can detect the tip position of is provided.

第１の被検知体１７ｆの取付位置高さと第１のセンサ３１の取付位置高さ、第２のセンサ３２の取付位置高さは、ベース１９の上下移動により上下する上刃５の上端位置（上死点位置）と下端位置（下死点位置）を検出するために設けられている。例えば、図１に示すようにベース１９をシリンダ装置２７により一番高い位置に引き上げた場合、上刃５は刃先部５ａを搬送路３の上方に所定の距離をあけて停止する。この位置が上刃５の上死点であり、上刃５がこの位置であることを第１のセンサ３１が被検知体１７ｆの位置を検出することで把握することができる。
また、シリンダ装置２７によりベース１９を一番下まで下降させると、上刃５の刃先部５ａは搬送路３を横切って下刃６の刃先部６ａより下方の位置まで下降する。この位置が上刃５の下死点であり、上刃５がこの位置であることを第２のセンサ３２が被検知体１７ｆの接近で検知する。 The mounting position height of the first detected body 17f, the mounting position height of the first sensor 31, and the mounting position height of the second sensor 32 are the upper end position of the upper blade 5 that moves up and down by the vertical movement of the base 19 ( It is provided to detect the top dead center position) and the bottom edge position (bottom dead center position). For example, as shown in FIG. 1, when the base 19 is pulled up to the highest position by the cylinder device 27, the upper blade 5 stops the blade edge portion 5 a with a predetermined distance above the conveyance path 3. This position is the top dead center of the upper blade 5, and it can be grasped by the first sensor 31 detecting the position of the detected body 17f that the upper blade 5 is in this position.
Further, when the base 19 is lowered to the lowest position by the cylinder device 27, the blade edge portion 5 a of the upper blade 5 is lowered to a position below the blade edge portion 6 a of the lower blade 6 across the conveying path 3. This position is the bottom dead center of the upper blade 5, and the second sensor 32 detects that the upper blade 5 is in this position by the approach of the detected object 17f.

前記搬送路３において搬送テーブル１３の下流側には搬送テーブル１５との間に幅広の間隙ｄが形成され、この間隙ｄの下側に紙葉類の送り出しのための送出装置３５が設けられている。この送出装置３５は案内ローラ３６と補助ローラ３７を有し、搬送路３の上に水平に載置された合紙９をこれらのローラ３６、３７で挟んでローラ３６、３７を回転させることで搬送路３の下流側（図１の右側に）に切断後の合紙９を送り出すことができる。なお、送出装置３５は搬送路３の間隙ｄの下方に斜め上向きに設置されている。送出装置３５は図示略の上下移動機構によりローラ３６、３７を上下に移動自在に設けられており、必要に応じてローラ３６、３７の上下位置を調整して搬送路３上の合紙９を送り出すことができるが、図１では送出装置３５の上下移動機構については記載を略している。   A wide gap d is formed between the conveyance path 3 and the conveyance table 15 on the downstream side of the conveyance table 13, and a feeding device 35 for feeding paper sheets is provided below the gap d. Yes. This feeding device 35 has a guide roller 36 and an auxiliary roller 37, and the rollers 36, 37 are rotated by sandwiching the interleaving paper 9 placed horizontally on the conveying path 3 between these rollers 36, 37. The cut slip sheet 9 can be sent to the downstream side of the transport path 3 (on the right side in FIG. 1). The delivery device 35 is installed obliquely upward below the gap d in the transport path 3. The feeding device 35 is provided so that the rollers 36 and 37 can be moved up and down by a vertical movement mechanism (not shown). Although it can be sent out, the vertical movement mechanism of the sending device 35 is not shown in FIG.

以上説明の切断装置１を用いて合紙９を切断するには、シリンダ装置２７のピストンロッド２７ａを上昇させて図１に示すように上刃５を上死点位置まで上昇させ、搬送路３の上方に間隔をあけて支持しておく。
この状態において、駆動ロール８とともに供給ロール２を回転させ、供給ロール２から合紙９を必要長さ搬送路３上に引き出し、引き出した合紙９を搬送路３に沿って水平に設置する。
合紙９を必要長さ引き出した時点で合紙９の引き出しを停止し、シリンダ装置２７のピストンロッド２７ａを下降させ、ベース本体１７と上刃５を下降させる。 In order to cut the slip sheet 9 using the cutting device 1 described above, the piston rod 27a of the cylinder device 27 is raised to raise the upper blade 5 to the top dead center position as shown in FIG. It is supported above with a space.
In this state, the supply roll 2 is rotated together with the drive roll 8, the interleaf sheet 9 is pulled out from the supply roll 2 onto the necessary length of the conveyance path 3, and the extracted interleaf sheet 9 is installed horizontally along the conveyance path 3.
When the required length of the slip sheet 9 is pulled out, the pulling out of the slip sheet 9 is stopped, the piston rod 27a of the cylinder device 27 is lowered, and the base body 17 and the upper blade 5 are lowered.

ここで上刃５はその刃先部５ｂを下にして下刃６の刃先部６ｂの先端前方の間隙Ｄを上から下に通過するので、下刃６の刃先部６ｂと上刃５の刃先部５ｂとで合紙９を挟んで合紙９を幅方向に切断できる。上刃５が下刃６とともに合紙９を挟んで切断する際、図２（ａ）〜図２（ｂ）に示すように刃先部６ｂの前方を合紙９を挟んで狭い間隔（０〜０．０１ｍｍ程度）で刃先部５ｂが通過するので、上刃５の刃先部５ｂより上側（基端側）の側面を刃先部６ｂの先端が擦り付けて摩耗させるおそれがある。しかし、上刃５において刃先部５ｂより上側には凹溝型の逃げ部５ｃが形成されているので、刃先部６の先端が上刃５の側面を摩耗させるおそれが少なく、摩耗粉の発生を抑制できる。このため、切断した合紙９の上面に上刃５からの摩耗粉を落下させることがない。
なお、上述の合紙９をフラットパネルディスプレイ用ガラス基板の梱包用として用いた場合、合紙９の上に摩耗粉が存在すると、ガラス基板側に摩耗粉を付着させてしまうおそれがあるが、本実施形態の切断装置１を用いて合紙９を切断することにより、摩耗粉の付着を無くすることができる。 Here, the upper blade 5 passes the gap D in front of the tip of the blade edge portion 6b of the lower blade 6 from the upper side to the lower edge with the blade edge portion 5b down, so the blade edge portion 6b of the lower blade 6 and the blade edge portion of the upper blade 5 The interleaf sheet 9 can be cut in the width direction by sandwiching the interleaf sheet 9 with 5b. When the upper blade 5 is cut along with the lower blade 6 with the interleaf paper 9 interposed therebetween, as shown in FIGS. 2A to 2B, the front edge of the blade edge portion 6b is narrowly spaced with the interleaf paper 9 interposed therebetween (0 to 0). Since the blade edge portion 5b passes at about 0.01 mm, the tip of the blade edge portion 6b may rub against the side surface of the upper blade 5 above the blade edge portion 5b (base end side). However, since the concave portion 5c is formed on the upper blade 5 above the blade edge portion 5b, the tip of the blade edge portion 6 is less likely to wear the side surface of the upper blade 5, and generation of wear powder is prevented. Can be suppressed. For this reason, the abrasion powder from the upper blade 5 is not dropped on the upper surface of the cut slip sheet 9.
In addition, when the above-mentioned slip sheet 9 is used for packing a glass substrate for a flat panel display, if wear powder is present on the slip sheet 9, there is a possibility that the wear powder may adhere to the glass substrate side. By cutting the slip sheet 9 using the cutting device 1 of the present embodiment, it is possible to eliminate the attachment of wear powder.

合紙９を上刃５と下刃６とで切断すると、シリンダ装置２７がピストンロッド２８を上昇させて上刃５を上端位置まで上昇させるとともに、送出装置３５が案内ローラ３６と補助ローラ３７で合紙９を挟んで搬送路３の下流側に送るので、上刃５と下刃６の間の搬送路３が空いた状態となる。ここで、再び供給ロール２から合紙９を搬送路３に必要長さ送り出すことができ、上刃５の上述と同じ作動により合紙９を切断できる。
以上の操作の繰り返しにより合紙９を多数枚切断した場合、上刃５を支持しているベース本体１７が側壁１７Ａ、１７Ｂと接続壁１７Ｃ、１７Ｄからなる堅牢な鋼材からなる中空構造とされていて、従来の単板状のベースよりも剛性を向上させた、ベース１９とされているので、ベース１９が歪むおそれは少なく、上刃５の位置ずれを起こすおそれが少ない。このため、フラットパネルディスプレイ用ガラス基板の梱包用などのような大型の合紙９を多数切断したとしても、切断刃５、６の切れ味が鈍るおそれが少なく、切断精度が低下することもない。
また、ベース本体１７はその底部を貫通している複数本の補強材１８により更に強化されているので、ベース１９の剛性を更に高くできており、切断精度に狂いが生じ難い切断装置１を提供できる。 When the slip sheet 9 is cut by the upper blade 5 and the lower blade 6, the cylinder device 27 raises the piston rod 28 to raise the upper blade 5 to the upper end position, and the feeding device 35 is guided by the guide roller 36 and the auxiliary roller 37. Since the interleaving paper 9 is sandwiched and sent to the downstream side of the conveyance path 3, the conveyance path 3 between the upper blade 5 and the lower blade 6 becomes empty. Here, the required length of the interleaving paper 9 can be sent again from the supply roll 2 to the conveying path 3, and the interleaving paper 9 can be cut by the same operation as described above of the upper blade 5.
When a large number of slip sheets 9 are cut by repeating the above operation, the base body 17 supporting the upper blade 5 has a hollow structure made of a solid steel material including side walls 17A, 17B and connection walls 17C, 17D. Since the base 19 has improved rigidity compared to the conventional single plate base, the base 19 is less likely to be distorted and the upper blade 5 is less likely to be displaced. For this reason, even if a large number of large slip sheets 9 such as those for packing a glass substrate for a flat panel display are cut, the cutting blades 5 and 6 are less likely to become dull and the cutting accuracy is not lowered.
Further, since the base body 17 is further reinforced by a plurality of reinforcing members 18 penetrating the bottom thereof, the base 19 can be further increased in rigidity, and the cutting apparatus 1 is provided in which the cutting accuracy is unlikely to occur. it can.

また、シリンダ装置２７のピストンロッド２８を上昇させてベース１９を上端位置まで上昇させた場合、必要に応じてストップ機構３０を動作させてストップピン３０ａをベース本体１７の係止孔１７ｅに挿通することにより、ベース本体１７の下降を阻止できる。このため、上刃５の下降を阻止した状態とすることが確実にできるので、装置のメンテナンス時に上刃５を上昇させたまま安全にメンテナンス作業ができる。   When the piston rod 28 of the cylinder device 27 is raised to raise the base 19 to the upper end position, the stop mechanism 30 is operated as necessary to insert the stop pin 30a into the locking hole 17e of the base body 17. Thus, the lowering of the base body 17 can be prevented. For this reason, since it can be made into the state which prevented the fall of the upper blade 5, it can maintain safely with the upper blade 5 raised at the time of the maintenance of an apparatus.
