【考案の詳細な説明】
本考案は複写機等にむける紙搬送装置に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a paper conveyance device for copying machines and the like.
従来紙搬送装置としては第１図に示すようにガイド板５
１に形成された穴５２に球５３を回動自在に装着したも
のが多く用いられていた。As shown in FIG. 1, a conventional paper conveying device has a guide plate 5.
In many cases, a ball 53 was rotatably mounted in a hole 52 formed in the ball 1.
このような紙搬送装置では、ジアゾ複写機に用いられる
場合のように紙を円滑に案内するためには多くの球を必
要とし、したがって一枚のガイド板に多数の穴を絞り加
工等により形成する必要がある。Such paper conveyance devices require many balls to guide the paper smoothly, such as those used in diazo copying machines, and therefore a large number of holes are formed in one guide plate by drawing, etc. There is a need to.
多数の穴を絞り加工することは手間のかかることであり
、ガイド板の平面度の維持がむずかしい。Drilling a large number of holes is time-consuming and difficult to maintain the flatness of the guide plate.
単に穴をプレス等によりあけるだけの場合には加工には
あ１り手間がかからないが、平面度の維持がむずかしく
、又球がガイド板から回転力により飛び出す危険がある
。If the holes are simply made using a press or the like, the machining process does not take much time, but it is difficult to maintain flatness, and there is a risk that the balls may fly out of the guide plate due to rotational force.
球の飛び出しを防止するためにはガイド板がほぼ球の中
心を通るように配置する必要があり、このときにはガイ
ド板と搬送ベルトとの間隔が大きくなり、搬送される紙
の耳折れやジャム発生の原因となる。In order to prevent the ball from flying out, it is necessary to arrange the guide plate so that it passes almost through the center of the ball. In this case, the gap between the guide plate and the conveyor belt becomes large, which may cause folded edges or jams of the paper being conveyed. It causes
間隔を小さくするため球の径を小さくすると、球が軽く
なるので搬送力の低下を生ずることになり得策ではない
。If the diameter of the balls is made smaller in order to reduce the spacing, the balls will become lighter, which will result in a reduction in the conveying force, which is not a good idea.
本考案は上記の従来の紙搬送装置の欠点を解消し、安価
で平面度が容易に維持されベルトとの間隔を小さくする
ことのできるガイド板を有する紙搬送装置を提供するこ
とを目的としている。The present invention aims to solve the above-mentioned drawbacks of the conventional paper conveying device, and to provide a paper conveying device having a guide plate that is inexpensive, whose flatness is easily maintained, and whose distance from the belt can be reduced. .
本考案の詳細な図に示す実施例により説明する。The invention will now be explained by way of embodiments shown in detailed drawings.
第２図及び第３図において搬送ベルト１例えば無端ベル
ト１により紙が搬送される。In FIGS. 2 and 3, paper is conveyed by a conveyor belt 1, for example, an endless belt 1. In FIG.
搬送ベルト１により紙を、滑りを生じることなく確実に
搬送するために紙、を搬送ベルトに押圧しかつ紙のガイ
ドをなすガイド板２が設けられる。In order to reliably convey the paper by the conveyor belt 1 without causing slippage, a guide plate 2 is provided which presses the paper against the conveyor belt and guides the paper.
ガイド板２は所定の間隔で規則正しい凹凸状に形成され
ている。The guide plate 2 is formed with regular irregularities at predetermined intervals.
凹凸の形状とし、ては−例として図に示すように鋸刃状
に形成し、紙の側すなわち搬送ベルト１の側からみて、
紙の進行方向に凸部２ａから凹２ｂへへ移行する部分は
ほぼ直角に、凹部から凸部へ移行する部分は傾斜面とし
て形成されると、ガイド板２と搬送ベルト１との間を搬
送される紙の折れ曲がり及びジャムが防止される。It has an uneven shape, for example, it is formed into a saw blade shape as shown in the figure, and when viewed from the paper side, that is, the conveyor belt 1 side,
If the transition from the convex portion 2a to the concave portion 2b in the traveling direction of the paper is formed at a nearly right angle, and the portion transitioning from the concave portion to the convex portion is formed as an inclined surface, the paper can be conveyed between the guide plate 2 and the conveyor belt 1. This prevents paper from folding and jamming.
更にガイド板２の凸部２ａと搬送ベルト１との間の間隔
ａをできるだけ狭くすると紙のガイドが一層確実になる
。Further, if the distance a between the convex portion 2a of the guide plate 2 and the conveyor belt 1 is made as narrow as possible, the paper can be guided even more reliably.
ガイド板２の凹部２ｂを形成する板面には球の直径より
小さな直径の穴３が形成され、球４が回動自在に穴３に
はめ込オれている。A hole 3 having a diameter smaller than the diameter of the ball is formed in the plate surface forming the recess 2b of the guide plate 2, and a ball 4 is fitted into the hole 3 so as to be rotatable.
穴３が形成される板面ばベルト面から球４の半径より犬
で直径より小なる位置にくるように設定される。The plate surface on which the hole 3 is formed is set to be at a position smaller than the diameter of the ball 4 from the belt surface.
本考案によりガイド板が凹突形状に形成されることによ
り、ガイド板と搬送コンベアの間隔を最適の狭い間隔に
保持され、しかも球４が紙を搬送ベルト１にしつかり抑
圧できるように装着されることができる。By forming the guide plate into a concave shape according to the present invention, the distance between the guide plate and the conveyor can be maintained at an optimally narrow interval, and the balls 4 are mounted so as to hold and suppress the paper on the conveyor belt 1. be able to.
球４例えば鋼球４は高速度紙搬送により高速回転しても
、ガイド板２に形成された穴３の直径を球４の直径より
も小さいため、球４がガイド板２から飛び出すことが防
止できる。Even if the ball 4, for example, the steel ball 4, rotates at high speed due to high-speed paper conveyance, the diameter of the hole 3 formed in the guide plate 2 is smaller than the diameter of the ball 4, so the ball 4 is prevented from jumping out from the guide plate 2. can.
ガイド板２は凹凸に形成されることにより、ガイド板２
は折り曲げ形成されることになり、剛性が増す。The guide plate 2 is formed in an uneven manner so that the guide plate 2
is formed by bending, increasing the rigidity.
又ガイド板２の撓みが小さくおさえることができ、ガイ
ド板２の平面度も保持されることができる。Further, the deflection of the guide plate 2 can be suppressed to a small extent, and the flatness of the guide plate 2 can also be maintained.
本考案によりガイド板には球を装着する穴を深絞り加工
する必要もなく、少量生産にむいても安価ガイド板が得
られる。According to the present invention, there is no need to deep draw holes for mounting balls in the guide plate, and an inexpensive guide plate can be obtained even for small-scale production.
