Description

本発明は、エスカレータのレール製造方法に係り、特に、平板を曲げ加工して成形するエスカレータのレール製造方法に関する。   The present invention relates to an escalator rail manufacturing method, and more particularly, to an escalator rail manufacturing method in which a flat plate is bent and formed.

エスカレータは、上階床と下階床とに跨って設置される枠に複数のレールを連設して配置し、これらのレール上を踏段に設けられたローラが転動することで、複数の踏段が案内されつつ循環移動するようになっている。   The escalator arranges a plurality of rails in a continuous manner on a frame installed across the upper floor and the lower floor, and the rollers provided on the steps roll on these rails, thereby The steps are circulated while being guided.

図8は従来のエスカレータのレール製造方法を示す斜視図である。   FIG. 8 is a perspective view showing a conventional escalator rail manufacturing method.

従来、レール10は、平板に曲げ加工を施すことで、ローラが転動する転動面10aと、この転動面10aと直交し、ローラの外側面と対向する案内壁面10bとを形成するようになっていた。   Conventionally, the rail 10 is formed by bending a flat plate to form a rolling surface 10a on which the roller rolls and a guide wall surface 10b orthogonal to the rolling surface 10a and facing the outer surface of the roller. It was.

しかしながら、前述した従来のものでは、平板を所定の角度まで曲げ加工することに伴う捩れから、図8に示すように、レール10の端部に局部膨れ10cが生じていた。エスカレータは複数のレールが連設されて踏段の移動を案内する構造であり、レールの端部に局部膨れがあると、レールとレールとの継ぎ目に隙間が生じ、振動や騒音の原因となる。このため、作業員の手作業で局部膨れを除去する加工をしていたが、この作業に手間がかかるとともに、十分に局部膨れが除去されない状態で据付けられ、エスカレータの精度を低下させる恐れもあった。   However, in the conventional device described above, a local bulge 10c is generated at the end of the rail 10, as shown in FIG. 8, due to the twist associated with bending the flat plate to a predetermined angle. An escalator has a structure in which a plurality of rails are connected in series to guide the movement of a step. If there is a local bulge at the end of the rail, a gap is formed at the joint between the rails, causing vibration and noise. For this reason, the worker manually removes the local bulge, but this work is time-consuming and may be installed in a state where the local bulge is not sufficiently removed, which may reduce the accuracy of the escalator. It was.

本発明は、前述した従来技術における実状からなされたもので、その目的は、曲げ加工により局部膨れが生じることを防ぐことのできるエスカレータのレール製造方法を提供することにある。   The present invention has been made from the above-described prior art, and an object of the present invention is to provide a method of manufacturing an escalator rail that can prevent local swelling due to bending.

前記目的を達成するために、本発明の請求項1に係る発明は、上階床と下階床とに跨って設置される枠と、無端状に連結され前記枠内を循環移動する複数の踏段と、前記枠に連続して取付けられ、前記踏段に設けられるローラが転動する転動面、およびこの転動面と直交し、前記ローラの外側面と対向する案内壁面とを少なくとも有する複数のレールとを備えたエスカレータのレール製造方法において、平板の長手方向端部に、長手方向に向かって所定の奥行き寸法を有するとともに、短手方向に向かって所定の幅寸法を有する切込みを形成し、次いで、前記切込みに沿って前記平板に曲げ加工を施し、少なくとも前記転動面および前記案内壁面を形成することを特徴としている。   In order to achieve the above object, an invention according to claim 1 of the present invention includes a frame installed across an upper floor and a lower floor, and a plurality of endlessly connected frames that circulate in the frame. A plurality of steps having at least a step, a rolling surface that is continuously attached to the frame and on which a roller provided on the step rolls, and a guide wall surface that is orthogonal to the rolling surface and faces the outer surface of the roller In the rail manufacturing method of the escalator including the rail, a notch having a predetermined depth dimension in the longitudinal direction and a predetermined width dimension in the lateral direction is formed at the longitudinal end portion of the flat plate. Then, the flat plate is bent along the notches to form at least the rolling surface and the guide wall surface.

本発明の請求項1に係る発明では、あらかじめ平板の長手方向端部に切込みを形成し、この後、この切込みに沿って平板を曲げ加工を施すことで、曲げ加工に伴う捩れにより局部膨れが生じることを防ぐことができる。   In the invention according to claim 1 of the present invention, a notch is formed in the longitudinal end portion of the flat plate in advance, and thereafter, the flat plate is bent along the notch so that the local swelling is caused by the twist associated with the bending. It can be prevented from occurring.

本発明によれば、曲げ加工により局部膨れが生じることを防ぐことでレールとレールとの継ぎ目を円滑なものとし、これによって、振動や騒音の少ない高精度なエスカレータを実現することができる。   According to the present invention, the joint between the rails can be made smooth by preventing the occurrence of local bulging by bending, thereby realizing a highly accurate escalator with less vibration and noise.

以下、本発明に係るエスカレータのレール製造方法の実施の形態を図に基づいて説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a rail manufacturing method for an escalator according to the present invention will be described based on the drawings.

Is a schematic configuration diagram of an escalator to which the present invention is applied, FIG. 5 is a perspective view of a portion A of FIG. 1 showing a joint portion of a rail of the escalator, FIG. 6 is a view corresponding to FIG. FIG. 7 is a view corresponding to FIG. 2 showing still another shape of the cut.

エスカレータは、図4に示すように、上階床と下階床とに跨って設置される枠に複数のレール1を連設して配置し、これらのレール1上を踏段2に設けられたローラ3が転動することで、踏段2が案内されつつ循環移動するようになっている。   As shown in FIG. 4, the escalator is provided with a plurality of rails 1 connected to a frame installed across the upper floor and the lower floor, and provided on the step 2 on these rails 1. As the roller 3 rolls, the step 2 is circulated while being guided.

そして、レール1は、まず、図2に示すように、平板1aの長手方向端部に、長手方向に向かって所定の奥行き寸法を有するとともに、短手方向に向かって所定の幅寸法を有する切込み1bを形成する。なお、図3に示すように、本実施形態では前述した奥行き寸法が、例えば0.5mm、幅寸法が、例えば20mmにそれぞれ設定されている。次いで、切込み1bに沿って平板1aに曲げ加工を施し、ローラ3が転動する転動面1cと、この転動面1cと直交し、ローラ3の外側面と対向する案内壁面1dとを形成する。また、転動面1cの端部には、ローラ3の脱落防止として内側面と対向する内側案内壁面1eが曲げ加工により形成されるが、この内側案内壁面1eは、曲げ加工しても局部膨れが生じない45度以下の曲げ角度であることから、切込みをあらかじめ形成する必要はない。すなわち、45度以上の曲げ加工を行なう場合に切込みを設けることで局部膨れが生じることを防ぐものである。この後、図1および図5に示すように、複数のレール1を連設して配置することで、踏段2の走行路を形成するが、このとき、互いのレール1の端部には局部膨れがないことから、レール1とレール1との継ぎ目を密着させて配置することが可能となる。   As shown in FIG. 2, first, the rail 1 has a predetermined depth dimension in the longitudinal direction and a predetermined width dimension in the lateral direction at the longitudinal end portion of the flat plate 1a. 1b is formed. As shown in FIG. 3, in the present embodiment, the depth dimension described above is set to 0.5 mm, for example, and the width dimension is set to 20 mm, for example. Next, the flat plate 1a is bent along the notch 1b to form a rolling surface 1c on which the roller 3 rolls, and a guide wall surface 1d that is orthogonal to the rolling surface 1c and faces the outer surface of the roller 3. To do. In addition, an inner guide wall surface 1e facing the inner surface is formed by bending at the end of the rolling surface 1c so as to prevent the roller 3 from falling off. The inner guide wall surface 1e is locally swollen even when bent. Therefore, it is not necessary to form a cut in advance. That is, when a bending process of 45 degrees or more is performed, a local bulge is prevented by providing a cut. Thereafter, as shown in FIG. 1 and FIG. 5, a plurality of rails 1 are arranged in series to form a travel path for the step 2, but at this time, local ends are located at the ends of the rails 1. Since there is no swelling, the joint between the rail 1 and the rail 1 can be disposed in close contact.

本実施形態によれば、曲げ加工により局部膨れが生じることを防ぐことでレール1とレール1との継ぎ目を円滑なものとし、これによって、振動や騒音の少ない高精度なエスカレータを実現することができる。また、切込み1bの奥行き寸法を0.5mm、幅寸法を20mmに設定することで、曲げ加工により局部膨れが生じることを防ぐとともに、ローラ3が転動する際に切込み1b上を走行し振動や騒音が生じることを防ぐことができる。さらに、内側案内壁面1eを曲げ加工しても局部膨れが生じない45度以下の曲げ角度とすることにより切込みが不要となり、これによって、不要な工程をなくし、高効率な製造方法とすることができる。   According to the present embodiment, the joint between the rail 1 and the rail 1 is made smooth by preventing the occurrence of local bulging by bending, thereby realizing a highly accurate escalator with less vibration and noise. it can. In addition, by setting the depth dimension of the notch 1b to 0.5 mm and the width dimension to 20 mm, it is possible to prevent local bulging by bending and to run on the notch 1b when the roller 3 rolls. Generation of noise can be prevented. Further, by making the bending angle of 45 degrees or less that does not cause local swelling even when the inner guide wall surface 1e is bent, the incision becomes unnecessary, thereby eliminating unnecessary processes and providing a highly efficient manufacturing method. it can.

なお、本実施形態では、切込み1bの形状を略V字の断面形状を有するものとしたが、本発明はこれに限らず、例えば、図6に示すように、略U字の断面形状を有する切込み11bや、図7に示すように、略コ字の断面形状を有する切込み21bとしてもよい。   In the present embodiment, the shape of the cut 1b has a substantially V-shaped cross-sectional shape. However, the present invention is not limited to this, and for example, has a substantially U-shaped cross-sectional shape as shown in FIG. A cut 11b or a cut 21b having a substantially U-shaped cross section as shown in FIG.
