Description

【0001】
【発明の属する技術分野】
本発明は、円筒を把持する装置並びに方法に関するものであり、特に円筒の内径が異なるものに関する。
【0002】
【従来の技術】
膨張・収縮可能な弾性体に加圧気体(または加圧液体)を充填して膨張させることにより、円筒状基体の内側を把持する装置が種々開示されており、異径の円筒状基体内側を把持する装置も種々開示されている。
前記円筒状基体装置としては、給排通路から両端が密封されたチューブ内へ流体を供給して、チューブを膨張させたときに、可動部材がチューブの他端を一端に近づけるように、スライドすることにより、チューブの両端間の距離が縮まり、チューブの膨張が大きくなることによって、異径の円筒状基体も把持可能なものが提案され(例えば、特許文献1)、また、外筒に内筒の溝に嵌め込まれた円環状の弾性体を変形させて把持する作動ロッドに、Cワッシャを差込み簡単に把持装置を取付可能として、異径の円筒状基体も把持可能にしたものが提案されている(例えば、特許文献2参照)。
【0003】
特許文献1に開示されている円筒状基体把持装置の場合、異径のものに対して、チューブ外径の2倍程度まで把持可能であるが、チューブの膨張量には、限界があり、それ以上の円筒状基体を把持するとチューブがパンクする恐れがあった。
【0004】
異径のものに対して専用の把持装置を保有させた円筒状基体把持装置についての提案がなされているが、この提案によるとパンクする恐れ等はないが、専用の把持装置のため、決まった円筒状基体内径のものしか把持できないといった問題があった(例えば、特許文献2参照。)。

以下、図面により本発明について説明を行なう。
図1に、本発明の把持装置の筒状袋(2)の、大気下時(通常状態)、伸縮時(バキューム状態)および給気時(給気状態)の様子を示す。
該袋(2)の外径は、大気圧下では円筒基体(3)の内径(ΦX)よりも大きく、バキューム時では脱気パイプ(1)に張り付くほど小さくなり(ΦZ1)、また給気時では脱気パイプ(1)と平行になるよう膨らむ(ΦZ2)。
【0010】
図2は、筒状袋の変化状態を示すものである。
筒状袋(2)の上下部分の径は、円筒基体の径よりも大きなものとし、筒状袋(2)の中心部分を貫通するように、気体の給気とバキュームが可能な脱気パイプ(1)が設けられてある。
筒状袋(2)は、両端がシールされてあり、例えば図3に示されるように内径の異なる3つの円筒状基体(3)を用いる場合、通常状態時には3つの円筒状基体(3)の各内径Φd、Φd、Φdよりも大きな外径ΦDを有し、バキューム時にはこれらの3つの円筒状基体のすべての内径より小さい外径となるようにすることができ、円筒状基体内径が異なったものでも、円筒状基体把持装置を径に合わせて交換せずに、1つの円筒状基体把持装置にて円筒状基体を把持することが可能である。
【0011】
また、脱気パイプ(1)は、その外径ΦD’を、図3に示されるような円筒状基体(3)の内径Φd、Φd、Φdより小さく、かつ円筒状基体(3)を把持した時の軸(芯棒)となり、円筒状基体(3)の内径が異なったものでも、円筒状基体把持装置を径に合わせて交換せずに、1つの円筒状基体把持装置にて円筒状基体を把持することが可能である。
【0012】
筒状の袋(2)は、袋内部のエアーを脱気パイプ(1)よりバキュームすることにより、脱気パイプ(1)と筒状の袋(2)とが密着することにより、異径の円筒状基体のものも把持可能であり、円筒状基体内径が異なったものでも、円筒状基体把持装置を径に合わせて交換せずに、1つの円筒状基体把持装置にて円筒状基体を把持することが可能である。
【0013】
また、脱気パイプ(1)は、図2に示されるように筒状の袋(2)の両端を貫通しており、貫通している箇所は、筒状の袋内部のエアー漏れがないようにシールすることによって、円筒状基体内部を気密にすることが可能である。
【0014】
さらに、円筒状基体(3)内部に筒状の袋(2)を挿入する際には、図4のように、筒状の袋(2)は、バキューム状態にして、脱気パイプ(1)に密着した状態で挿入することにして、円筒状基体内径が異なったものでも、円筒状基体把持装置を径に合わせて交換せずに、1つの円筒状基体把持装置にて円筒状基体を把持することが可能である。
【0015】
図5は脱気パイプの例を示す図であり、図5−(a)に示される脱気パイプには給気・バキュームを兼ねた気体流路(4)を、また図5−(b)の脱気パイプに給気用気体流路(5)・バキュームの気体流路(6)を個々に有するものとすることができる。
【0016】
また、図6の例では、脱気パイプ(1)に給気用エアーバルブ(7)とバキューム用エアーバルブ(8)が設けられている。
【0017】
図7の例では、円筒状基体把持装置用袋を貫通して設けられた脱気パイプ(1)の上端には、円筒状基体を把持した際のフレを防止するためのテーパー部材(9)を有している。
テーパー部材は、例えば、図3の円筒状基体内径Φd、Φd、Φdの径に対応したテーパーを有しており、円筒状基体内径が異なったものでも、円筒状基体把持装置を径に合わせて交換せずに、1つの円筒状基体把持装置にて円筒状基体を把持することが可能である。
【0018】
図8の例では、円筒状基体把持装置用袋を貫通して設けられた脱気パイプ(1)の下端には、図3の円筒状基体内径Φd、Φd、Φdより小さく、円筒状基体内部に挿入する際の、ガイド部材(10)を有している。
【0019】
図2の筒状の袋(2)の材質は、非弾性部材(ポリプロピレン等)若しくは、弾性部材(NBR、EPDM等)である。
図3の異径の円筒状基体を把持した際には、筒状の袋が重なり合って隙間なく膨らむことによって、円筒状基体内部を気密状態とすることが可能である。
この円筒状基体把持装置は、電子写真感光体の製造装置に使用することが可能である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus and a method for gripping a cylinder, and more particularly to an apparatus and a method for gripping a cylinder having different inner diameters.
[0002]
[Prior art]
Various devices have been disclosed for gripping the inside of a cylindrical base by filling a pressurized gas (or pressurized liquid) into an expandable / contractible elastic body and expanding the same. Various gripping devices have been disclosed.
In the cylindrical base device, when a fluid is supplied from a supply / discharge passage into a tube whose both ends are sealed and the tube is expanded, the movable member slides so that the other end of the tube approaches one end. As a result, it has been proposed that the distance between both ends of the tube is reduced and the expansion of the tube is increased, so that a cylindrical substrate having a different diameter can be gripped (for example, Patent Document 1). A C-washer is inserted into an operating rod that deforms and holds an annular elastic body fitted in the groove of the above, so that a holding device can be easily attached, and a cylindrical body having a different diameter can also be held. (For example, see Patent Document 2).
[0003]
In the case of the cylindrical substrate gripping device disclosed in Patent Document 1, it is possible to grip a tube having a diameter different from that of a tube to about twice the outer diameter of the tube, but the amount of expansion of the tube is limited. When the above-mentioned cylindrical substrate is gripped, there is a risk that the tube will be punctured.
[0004]
A proposal has been made for a cylindrical substrate holding device that has a dedicated holding device for those having different diameters, but according to this proposal there is no danger of puncturing, etc. There has been a problem that only the inner diameter of the cylindrical substrate can be gripped (for example, see Patent Document 2).

Hereinafter, the present invention will be described with reference to the drawings.
FIG. 1 shows a state of the tubular bag (2) of the gripping device of the present invention in the atmosphere (normal state), during expansion and contraction (vacuum state), and during air supply (air supply state).
The outer diameter of the bag (2) is larger than the inner diameter (ΦX) of the cylindrical substrate (3) under atmospheric pressure, becomes smaller as it sticks to the deaeration pipe (1) during vacuum (ΦZ1), and Then, it expands so as to be parallel to the degassing pipe (1) (ΦZ2).
[0010]
FIG. 2 shows the changing state of the tubular bag.

The cylindrical bag (2) is sealed at both ends. For example, when three cylindrical substrates (3) having different inner diameters are used as shown in FIG. each inner diameter .PHI.d 1, .PHI.d 2, has a larger outer diameter ΦD than .PHI.d 3, it can be made to be all outer diameter smaller than the inner diameter of the three cylindrical substrate in vacuum during, the cylindrical body inner diameter However, it is possible to hold the cylindrical substrate with one cylindrical substrate holding device without replacing the cylindrical substrate holding device according to the diameter.

The degassing pipe (1) has an outer diameter ΦD ′ smaller than the inner diameters Φd 1 , Φd 2 , Φd 3 of the cylindrical body (3) as shown in FIG. 3, and the cylindrical body (3). Even when the cylindrical substrate (3) has a different inner diameter, the cylindrical substrate gripping device can be replaced with one cylindrical substrate gripping device without replacing the cylindrical substrate gripping device according to the diameter. It is possible to grip a cylindrical substrate.
[0012]
The cylindrical bag (2) has a different diameter because the air inside the bag is vacuumed from the degassing pipe (1) so that the degassing pipe (1) and the cylindrical bag (2) come into close contact with each other. It is also possible to hold a cylindrical substrate with one cylindrical substrate holding device without changing the cylindrical substrate holding device according to the diameter, even if the cylindrical substrate has a different inner diameter. It is possible to do.

The degassing pipe (1) penetrates both ends of the cylindrical bag (2) as shown in FIG. 2, and the penetrating portion is designed so that there is no air leakage inside the cylindrical bag. By sealing the inside, it is possible to make the inside of the cylindrical substrate airtight.
[0014]
Further, when inserting the cylindrical bag (2) into the cylindrical substrate (3), as shown in FIG. 4, the cylindrical bag (2) is set in a vacuum state and the deaeration pipe (1). Even when the cylindrical substrate has a different inner diameter, the cylindrical substrate holding device can be gripped by one cylindrical substrate holding device without replacing the cylindrical substrate holding device according to the diameter. It is possible to do.

[0018]
In the example of FIG. 8, the lower end of the deaeration pipe (1) provided through the bag for the cylindrical substrate holding device is smaller than the cylindrical substrate inner diameters φd 1 , φd 2 , and φd 3 of FIG. It has a guide member (10) for insertion into the inside of the substrate.
[0019]
The material of the cylindrical bag (2) in FIG. 2 is a non-elastic member (eg, polypropylene) or an elastic member (eg, NBR, EPDM).
When the cylindrical substrates of different diameters shown in FIG. 3 are gripped, the inside of the cylindrical substrate can be made airtight by overlapping the cylindrical bags and expanding without gaps.
The cylindrical substrate holding device can be used in an electrophotographic photoreceptor manufacturing apparatus.
[0020]
This cylindrical substrate gripping device allows the gas in the airtight space in the cylindrical substrate immersed in the coating liquid to flow out of the cylindrical substrate without flowing through the coating liquid in FIG.
