しかしながら、上述した特開平3−138294号公報に記載された乗客コンベアの改造方法では、既設フレームの長手方向の略全幅に亘って上面にガイドレールを設ける必要があり、乗客コンベアの改造工期が長くなってしまうとともに、改造コストが大幅にアップしてしまうという問題があった。   However, in the method for remodeling a passenger conveyor described in Japanese Patent Laid-Open No. 3-138294 described above, it is necessary to provide a guide rail on the upper surface over substantially the entire width in the longitudinal direction of the existing frame, and the time required for remodeling the passenger conveyor is long. As a result, there was a problem that the remodeling cost would be significantly increased.

また、上述した従来技術では左右方向を押える手段が無いため、新設コンベアユニット走行移動時に左右にずれてしまい、新設コンベアユニットが既設フレームに衝突し壊れるばかりでなく、最悪脱輪して作業者を傷つけるような事故につながる危険性がある。   In addition, since there is no means for pressing the left and right directions in the above-described conventional technology, the new conveyor unit shifts to the left and right when moving, and the new conveyor unit not only collides with the existing frame and breaks, but also causes the worker to escape from the worst. Risk of injury.

本発明は、上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、既設フレームにガイドレールを設置することなく、コンベアユニットを既設フレーム内の所定の収納位置まで安全に、かつ容易に移動させることを可能にする乗客コンベアの改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 its purpose is to move the conveyor unit safely and easily to a predetermined storage position in the existing frame without installing guide rails in the existing frame. It is an object of the present invention to provide a method for remodeling a passenger conveyor that makes it possible.

前記目的を達成するために、本発明の第1の手段は、既設乗客コンベアのうち既設フレームを残して、既設乗客コンベアを取り除き、無端状に配されて移動するステップ、このステップ及びこのステップと同期して移動するハンドレールを駆動する駆動装置及び前記ステップを案内するレールを含んだ各種の部品が装着された新しい乗客コンベアを、前記既設フレームの長手方向に複数個のコンベアユニットに分割し、その各コンベアユニットを前記既設フレームの長手方向に沿って前記既設フレーム内の所定の収納位置まで移動させて順次組み付けることで、前記既設フレームに前記新しい乗客コンベアを収納設置する乗客コンベアの改造方法において、前記各コンベアユニットに、前記既設フレームの上面に当接して回転するローラ部と、このローラ部の端縁部に設けられ前記既設フレームの長手方向に直交する方向への変位を規制するつば部と、このつば部と前記ローラ部との間に延設されるテーパ部とを有して構成したつば付走行ローラと、前記既設フレームの上面に取り外し可能で且つ前記ローラ部とつば部との間の段差より大きな高さ寸法を有するスロープ部材と、を取付けた後、前記つば付走行ローラのローラ部を前記既設フレームの上面及び前記スロープ部材上で転動させることにより、前記各コンベアユニットを前記既設フレーム内の所定の収納位置まで移動させて順次組み付けることで、前記既設フレーム内に前記新しい乗客コンベアを収納設置するようにしたことを特徴とする。 In order to achieve the above-mentioned object, the first means of the present invention is the step of leaving the existing frame among the existing passenger conveyors, removing the existing passenger conveyors, moving in an endless manner, this step, and this step. A new passenger conveyor equipped with various parts including a driving device that drives a handrail that moves synchronously and a rail that guides the step is divided into a plurality of conveyor units in the longitudinal direction of the existing frame, In a passenger conveyor remodeling method for storing and installing the new passenger conveyor in the existing frame by moving each conveyor unit along the longitudinal direction of the existing frame to a predetermined storage position in the existing frame and sequentially assembling the conveyor units. A roller portion that rotates in contact with the upper surface of the existing frame on each conveyor unit; A flange portion provided at an edge portion of the roller portion for restricting displacement in a direction perpendicular to the longitudinal direction of the existing frame, and a tapered portion extending between the flange portion and the roller portion is provided. a flanged running rollers configured by, after installing a slope member having a greater height dimension than the step between the possible and the roller portion removably to the upper surface and the flange portion of the existing frame, the flanged By rolling the roller portion of the traveling roller on the upper surface of the existing frame and the slope member, the conveyor units are moved to a predetermined storage position in the existing frame and sequentially assembled, thereby The new passenger conveyor is housed and installed.

また本発明の第2の手段は、第1の手段において、前記つば付走行ローラは、前記既設フレームの方向に押圧される押圧力付与手段を有し、前記押圧力付与手段により前記既設フレームの方向に押圧されながら前記既設フレームの上面及び前記スロープ部材上を転動することを特徴とする。 The second means of the present invention, in the first means, the running roller with the collar has a pressing force imparting means which is pressed in the direction of the existing frame, the existing frame by the pressing force imparting means It rolls on the upper surface of the existing frame and on the slope member while being pressed in the direction.

本発明によれば、既設フレームに新たにガイドレールを設置することなく、既設フレームの上面及びスロープ部材上を転動すると共に、つば部によって左右方向(前記既設フレームの長手方向に直交する方向)のずれを規制したつば付き走行ローラによって、各コンベアユニットを、安全に、かつ容易に既設フレーム内の所定の収納位置まで移動させることが可能となる。 According to the present invention, it rolls on the upper surface of the existing frame and on the slope member without newly installing a guide rail on the existing frame, and the left and right direction by the collar portion (direction orthogonal to the longitudinal direction of the existing frame). By using the travel rollers with the ribs that restrict the deviation, each conveyor unit can be safely and easily moved to a predetermined storage position in the existing frame.

また本発明によれば、つば付走行ローラにテーパ部を設けたため、既設フレームの上面部近傍に残部材があっても干渉しにくいので、つば付走行ローラの損壊を防止して安全に、かつ容易に既設フレーム内の所定の収納位置まで移動させることが可能となる。   Further, according to the present invention, since the tapered running roller is provided with a tapered portion, even if there is a remaining member near the upper surface portion of the existing frame, it is difficult to interfere with it. It can be easily moved to a predetermined storage position in the existing frame.

以下、本発明に係る乗客コンベアの改造を実施するための最良の形態を図に基づいて説明する。   Hereinafter, the best mode for carrying out a modification of a passenger conveyor according to the present invention will be described with reference to the drawings.

本発明の第1実施形態に係る乗客コンベアの改造方法について図1,2を用いて説明する。図1は本発明に係る乗客コンベアの改造方法の第1実施形態における、新設コンベアユニットを既設フレームに収納する手順を説明するための斜視図、図2は本発明に係る乗客コンベアの改造方法の第1の実施形態におけるつば付走行ローラの正面図である。   A method for remodeling a passenger conveyor according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view for explaining a procedure for housing a new conveyor unit in an existing frame in a first embodiment of a passenger conveyor remodeling method according to the present invention, and FIG. 2 is a passenger conveyor remodeling method according to the present invention. It is a front view of the travel roller with a collar in a 1st embodiment.

始めに、既設乗客コンベアをトラス構造からなる既設フレーム1のみを残した状態とし、他の部品をすべて撤去する。その場合、既設フレーム1の上弦部材1aの側面に補強のために連結した補強部材が取り付けられていれば、その補強部材を取り除いておく。   First, the existing passenger conveyor is left in a state where only the existing frame 1 made of a truss structure is left, and all other parts are removed. In that case, if the reinforcement member connected for reinforcement is attached to the side surface of the upper chord member 1a of the existing frame 1, the reinforcement member is removed.

次に、予め製作工場などにて複数に分割した新設コンベアユニット3を改造現場に搬入し、この新設コンベアユニット3に、少なくとも二対以上のつば付走行ローラ6を、取付けブラケット9および取付けボルト6aを介して取付ける。   Next, the newly installed conveyor unit 3 divided in advance at a production factory or the like is carried into the remodeling site, and at least two pairs of bridging travel rollers 6 are attached to the newly installed conveyor unit 3 with mounting brackets 9 and mounting bolts 6a. Install through.

ここで、つば付走行ローラ6は、既設フレーム1の上面に当接して回転するローラ部7と、このローラ部7の端縁部に設けられ既設フレーム1の長手方向に直交する方向への変位を規制するつば部7aと、このつば部7aと前記ローラ部7との間に延設されるテーパ部7cと、ローラ部7とつば部7aとを取付けブラケット9に固定されたローラ軸8へ回転可能に、しかも既設フレーム1の長手方向に直交する方向への変位可能にローラ移動量Sの隙間をもたせて取付けてある。   Here, the travel roller 6 with a collar is displaced in a direction perpendicular to the longitudinal direction of the existing frame 1 provided on the edge portion of the roller portion 7 and a roller portion 7 rotating in contact with the upper surface of the existing frame 1. To the roller shaft 8 fixed to the mounting bracket 9, the flange portion 7 a for restricting the flange portion, the tapered portion 7 c extending between the flange portion 7 a and the roller portion 7, and the roller portion 7 and the flange portion 7 a It is attached with a gap of the roller movement amount S so as to be rotatable and displaceable in a direction perpendicular to the longitudinal direction of the existing frame 1.

次に、既設フレーム1上部に据付雇い2を取付け、強固なチェーンやロープ等の索状体2aにて、据付雇い2と新設コンベアユニット3を接続する。   Next, the installation employer 2 is attached to the upper part of the existing frame 1, and the installation employer 2 and the new conveyor unit 3 are connected by a cord-like body 2a such as a strong chain or rope.

その後、既設フレーム上面1a上につば付走行ローラ6のローラ部7が当接するように位置を調整し、つば部7aで既設フレーム1の長手方向に直交する方向への変位を規制するようガイドさせながら新設コンベアユニット3をおろしていく。   Thereafter, the position is adjusted so that the roller portion 7 of the flanged traveling roller 6 contacts the existing frame upper surface 1a, and the collar portion 7a is guided to regulate the displacement in the direction orthogonal to the longitudinal direction of the existing frame 1. The new conveyor unit 3 is lowered.

同様に、他の新設コンベアユニット3を順次おろしていき、最後につば付走行ローラ6を取外し、新設コンベアユニット3同士を接続することで据付が完了する。   Similarly, the other newly installed conveyor units 3 are sequentially lowered, and finally the travel roller 6 with the collar is removed, and the newly installed conveyor units 3 are connected to each other to complete the installation.

なお、図1では上方より新設コンベアユニット3をおろしているが、下方より引き上げても良い。   Although the new conveyor unit 3 is lowered from above in FIG. 1, it may be pulled up from below.

このように構成した第1実施形態によれば、既設フレーム1の上面にガイドレールを取り付けることなく、既設フレーム1の上面1aを利用して、新設コンベアユニット3を、既設フレーム1内の所定の位置に移動させて、順次組み付けることができるので、改造工期の短縮及び改造コストの低減化が図られる。   According to the first embodiment configured as described above, the new conveyor unit 3 is attached to the predetermined frame in the existing frame 1 by using the upper surface 1a of the existing frame 1 without attaching guide rails to the upper surface of the existing frame 1. Since it can be moved to the position and assembled sequentially, the modification period can be shortened and the modification cost can be reduced.

さらに、つば付走行ローラ6が移動できる構成としているので、既設フレーム1の上面1a間の距離が変化しても、既設フレーム1に追従しスムーズに走行するので効率よく作業することが出来る。   Furthermore, since the travel roller 6 with a collar can be moved, even if the distance between the upper surfaces 1a of the existing frame 1 changes, it can follow the existing frame 1 and travel smoothly, so that it can work efficiently.

さらに、新設コンベアユニット3が左右に大きく蛇行した場合でも、つば付走行ローラ6につば部7aを設けているので、左右方向(既設フレーム1の長手方向に直交する方向)の移動量を制限し、脱落してしまうことを阻止できるので、安全に作業を行うことができる。   Furthermore, even when the newly installed conveyor unit 3 is meandering to the left and right, since the collar 7a is provided on the collar-equipped travel roller 6, the amount of movement in the left-right direction (the direction perpendicular to the longitudinal direction of the existing frame 1) is limited. Since it can be prevented from falling off, the work can be performed safely.

前述した通り、既設フレーム1の上弦部材1aに取り付いていた補強部材を取り除いているが、切断不可能な残部材1bは除去できない。そこで本実施形態によれば、つば付走行ローラ6にテーパ部7cを設けた。よって既設フレームの上面部1a近傍に残部材1bがあっても干渉しにくいので、つば付走行ローラの損壊を防止して安全に、かつ容易に既設フレーム内の所定の収納位置まで移動させることが可能となる。   As described above, the reinforcing member attached to the upper chord member 1a of the existing frame 1 is removed, but the uncuttable remaining member 1b cannot be removed. Therefore, according to the present embodiment, the tapered travel roller 6 is provided with the tapered portion 7c. Therefore, even if there is a remaining member 1b in the vicinity of the upper surface portion 1a of the existing frame, it is difficult to interfere, so that it is possible to prevent the bridging travel roller from being damaged and to move it safely and easily to a predetermined storage position in the existing frame. It becomes possible.

さらにテーパ部7cが残部材1bに干渉したとしても、ローラ移動量Sの範囲でローラ部7とつば部7aとを、図2中の実線と破線との間で変位可能としたので、実線の位置に変位すれば、残部材1bを回避可能であり、つば付走行ローラ6の損壊を防止して安全に、かつ容易に既設フレーム1内の所定の収納位置までコンベアユニット3を移動させることが可能となる。   Furthermore, even if the taper portion 7c interferes with the remaining member 1b, the roller portion 7 and the collar portion 7a can be displaced between the solid line and the broken line in FIG. If it is displaced to the position, it is possible to avoid the remaining member 1b, and it is possible to safely and easily move the conveyor unit 3 to a predetermined storage position in the existing frame 1 by preventing the bridging travel roller 6 from being damaged. It becomes possible.

次に、本発明の第2実施形態の構成を図3により説明する。図3は本発明に係る乗客コンベアの改造方法の第2の実施形態におけるつば付走行ローラの正面図である。   Next, the configuration of the second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a front view of a flanged traveling roller in a second embodiment of the passenger conveyor remodeling method according to the present invention.

この第2実施形態のつば付走行ローラ6は、前記既設フレーム1の方向にローラ部7とつば部7aと押圧するばね部からなる押圧力付与手段15を設けて構成したため、前記既設フレーム1の方向に、ローラ部7とつば部7aとが押圧されながら前記既設フレーム1の上面1a上を転動するよう構成している。   The travel roller 6 with the collar of the second embodiment is configured by providing a pressing force applying means 15 including a roller portion 7 and a spring portion that presses the collar portion 7 a in the direction of the existing frame 1. In the direction, the roller part 7 and the collar part 7a are configured to roll on the upper surface 1a of the existing frame 1 while being pressed.

従って前述のつば付走行ローラ6と同様に、テーパ部7cが残部材1bに干渉したとしても、ローラ移動量Sの範囲で変位すれば、残部材1bを回避可能であり、つば付走行ローラ6の損壊を防止して安全に、かつ容易に既設フレーム1内の所定の収納位置までコンベアユニット3を移動させることが可能となる。   Therefore, similarly to the above-described travel roller 6 with the collar, even if the taper portion 7c interferes with the remaining member 1b, the remaining member 1b can be avoided if it is displaced within the range of the roller movement amount S. It is possible to safely and easily move the conveyor unit 3 to a predetermined storage position in the existing frame 1.

さらに残部材1bを回避後は、ばね部15により押圧されて、回避前の位置へ戻るためコンベアユニット3の左右方向(既設フレーム1の長手方向に直交する方向)の移動量を確実に制限することができ、安全に効率よく作業することが出来る。   Further, after avoiding the remaining member 1b, the amount of movement of the conveyor unit 3 in the left-right direction (direction perpendicular to the longitudinal direction of the existing frame 1) is surely limited to be pressed by the spring portion 15 and return to the position before avoidance. Can work safely and efficiently.

この第2実施形態の押圧力付与手段15は、ばねに限らず、押圧力を付与できるものであれば油圧ダンパーなど他の部材でも同等の効果を得られる。   The pressing force applying means 15 of the second embodiment is not limited to a spring, and other members such as a hydraulic damper can obtain the same effect as long as the pressing force can be applied.

次に、本発明の第3実施形態の構成を図4,5により説明する。図4は本発明に係る乗客コンベアの改造方法の第3の実施形態におけるスロープ部の取付け状態を示す斜視図、図5は本発明に係る乗客コンベアの改造の第3の実施形態におけるつば付走行ローラの正面図である。   Next, the configuration of the third embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a perspective view showing an attachment state of the slope portion in the third embodiment of the passenger conveyor remodeling method according to the present invention, and FIG. 5 is a brim travel in the third embodiment of the passenger conveyor remodeling according to the present invention. It is a front view of a roller.

本発明の第1実施形態で説明したように、既設フレーム1の上面1aに取り付いていた補強部材を取り除く作業があるが、切断不可能な残部材1bが残ってしまう。この状態で、既設フレーム1上を走行してきたつば付走行ローラ6は残部材1bに接触するため、乗り上げて通過しなければない。しかし、コンベアユニット3は重量物であるために乗り上げるのには相当の力が必要であり、つば付走行ローラ6も相当な強度が必要となってしまう。   As described in the first embodiment of the present invention, there is an operation of removing the reinforcing member attached to the upper surface 1a of the existing frame 1, but the uncuttable remaining member 1b remains. In this state, the travel roller 6 with the collar that has traveled on the existing frame 1 contacts the remaining member 1b, and therefore has to ride and pass. However, since the conveyor unit 3 is heavy, a considerable force is required to ride on the conveyor unit 3, and the bridging travel roller 6 also requires a considerable strength.

そこで、本発明の第3実施形態は、残部材1b付近の既設フレーム1の上面1aに取外し可能で且つ前記ローラ部とつば部7aとの間の段差H2より大きな高さ寸法H1を有するスロープ部材10をスロープ部材取付けボルト11、ナット12を介して取付け、このスロープ部材10上を前記つば付走行ローラ6を転動させるようにした。 Therefore, in the third embodiment of the present invention, the slope having a height dimension H1 that can be removed from the upper surface 1a of the existing frame 1 near the remaining member 1b and that is larger than the step H2 between the roller portion 7 and the flange portion 7a. The member 10 is mounted via a slope member mounting bolt 11 and a nut 12, and the travel roller 6 with a collar is caused to roll on the slope member 10.

このように構成した第3実施形態によれば、つば付走行ローラ6が残部材1bを通過する際、スロープ部材10上を走行するため、上弦部材出張り部1bと接触することなくスムーズに走行するので効率よく作業することが出来る。   According to the third embodiment configured as described above, when the travel roller 6 with the collar travels on the slope member 10 when passing through the remaining member 1b, it travels smoothly without coming into contact with the upper chord member projecting portion 1b. So you can work efficiently.
