【考案の詳細な説明】
（産業上の利用分野）
本考案は、印刷機、複写機等における、修理、
交換を容易にした、用紙送り出しロールに関す
る。[Detailed description of the invention] (Field of industrial use) This invention is suitable for repair, repair, etc. of printing machines, copying machines, etc.
This invention relates to a paper feed roll that is easy to replace.
（従来の技術）
印刷機、複写機等の用紙（カツトシート）を取
扱う装置においては、用紙送り出しのため回転軸
に数個のデイスク状ロールを嵌装、固定したロー
ル装置が用いられることが多い。(Prior Art) In devices that handle paper (cut sheets), such as printing machines and copying machines, a roll device in which several disc-shaped rolls are fitted and fixed to a rotating shaft is often used to feed the paper.
この種のロールは円形または半月形をなし、用
紙の搬送を確実にするため、その外周の円周面に
ラバーを接着するか或はロール全体をラバーで製
作し、かつこれらのロールを回転軸と一体化して
いる。 This type of roll has a circular or half-moon shape, and in order to ensure paper conveyance, rubber is glued to the outer circumferential surface or the entire roll is made of rubber, and these rolls are rotated around a rotating shaft. It is integrated with.

スエンジニヤによつてロール装置をアセンブリと
して一括して交換していた。 By the way, during use, the rubber part of the paper feed roll that comes into contact with the paper and feeds it out may lose its initial performance due to factors such as wear, deterioration over time, and adhesion of paper dust, etc. For example, misfeeding may occur. It becomes impossible to fully perform its functions. Therefore, during periodic inspections, etc., the roll device was replaced all at once as an assembly by a service engineer.

た場合に専問いでないユーザでは必要に応じて修
理するわけにゆかず、サービスエンジニヤに依頼
しなければならなかつた。 As mentioned above, the structure of a conventional roll device is such that a disk-shaped roll is fitted and fixed on a shaft, and one of the several rolls cannot be replaced. Even if the rolls are replaced as an assembly, both ends are supported by bearings and there is a transmission connected to a drive source beyond that, so if a defect is discovered in the rolls, non-specialized users will not be able to do so. It was not possible to repair it as needed, so we had to ask a service engineer to do it.
そのため、従来の用紙送り出しロールは、その
修理、交換のため長時間機械を停止することを余
儀なくされ、またその費用も高価につくという欠
点を免れなかつた。 Therefore, conventional paper feed rolls have the disadvantage that the machine has to be stopped for a long time for repair or replacement, and the costs are high.
（考案が解決しようとする問題点）
本考案は、ユーザが必要に応じて容易にかつ安

換することが可能になつた。(Means and effects for solving the problem) According to the present invention, the paper feed roll is composed of a half-moon-shaped core attached to a rotating shaft and an endless belt-shaped rubber that is detachable from the core. consists of a core body to which the belt is attached and a cylindrical part fitted and fixed to the rotating shaft, and a belt attachment/detaching groove that opens to one side in the axial direction is formed between the core body and the cylindrical part. By doing so, when the belt-shaped rubber wears out, it has become possible to replace it with a new one very easily.
（実施例）
以下、図面を参照し、実施例に基づいて本考案
を説明する。(Example) Hereinafter, the present invention will be described based on an example with reference to the drawings.
本考案による用紙送り出しロールは、第１図

月状コア１と、これに着脱可能な無端ベルト状ラ
バー６とから構成されている。 As shown in FIGS. 1a and 1b, the paper feed roll according to the present invention is composed of a half-moon-shaped core 1 attached to a rotating shaft 7 and an endless belt-shaped rubber 6 that can be attached to and detached from the half-moon-shaped core 1.

コア本体２と円筒部３の間には溝５が形成されて
いる。すなわち、コア本体２と円筒部３とはコア
１の一端部においてのみ連結され、他端は自由に
出入しうるようになつている。 The core 1 includes a core body 2 to which a belt 6 is attached on the circumferential surface, a core body 2 fitted to a shaft 7, and a pin 8 to which a belt 6 is attached.
It consists of a cylindrical part 3 fixed in a predetermined position by
A groove 5 is formed between the core body 2 and the cylindrical portion 3. That is, the core body 2 and the cylindrical part 3 are connected only at one end of the core 1, and the other end can freely go in and out.
無端ベルト状ラバー６は、上記の溝５を利用し

ラバー６を挟持するようになつている。 The endless belt-like rubber 6 is attached to the circumferential surface of the core body 2 using the groove 5 (inside the groove 5, the rubber 6 is pulled from both ends of the core body 2, so it is rather attached to the cylindrical part). 3),
In order to prevent displacement in the axial direction, collars 4, 4 are provided along both end surfaces of the core body 2, and the rubber 6 is held between them.

できる。 First, the core 1 is fitted onto the shaft 7 and fixed in a predetermined position by driving the pin 8. Then, the assembly is completed by attaching the endless belt-like rubber 6. Since the rubber 6 wears out during use, its position is shifted in the circumferential direction of the rubber 6 at an appropriate time to expose a new surface. Furthermore, the rubber 6 is replaced at an appropriate time thereafter. When replacing, insert rubber 6 into groove 5.
By pulling it out to the side, only the rubber 6 can be replaced with a new one, leaving the core body 2 as is.

できる。(Effect of the invention) Since the paper feed roll according to the invention is configured as described above, when the paper delivery roll according to the invention ceases to function adequately due to causes such as wear, aging, and adhesion of paper powder, the paper feed roll can be used immediately. , and can be replaced with a new one extremely easily and without the hassle of a service engineer, minimizing the downtime of mechanical equipment such as printing machines and copying machines where paper feed rolls are installed. Productivity can be improved.
しかも、必要な無端ベルト状ラバーの交換のみ
で済むので、修理の経費を節約することができ、
経済的にもきわめて有利である。 What's more, all you need to do is replace the endless belt-shaped rubber, so you can save on repair costs.
It is also extremely advantageous economically.
