Description

燃料タンク内蔵部品及び燃料タンク内蔵部品の取付方法Fuel tank built-in parts and fuel tank built-in parts mounting method
　本発明は、燃料タンク内蔵部品及び燃料タンク内蔵部品の取付方法に関する。 The present invention relates to a fuel tank built-in component and a method for mounting the fuel tank built-in component.
　従来、自動車等の燃料タンクを製造する際に、ブロー成形等で製造される燃料タンク本体の内部に、ブラケットや波消板等の燃料タンク内蔵部品を取り付けることが行われている。燃料タンク内蔵部品を取り付ける際には、燃料タンク内蔵部品を昇降自在に支持する昇降装置を使用し、金型の所定位置に燃料タンク内蔵部品を配置するのが一般的である。 Conventionally, when a fuel tank for an automobile or the like is manufactured, a fuel tank built-in component such as a bracket or a wave-dissipating plate is attached to the inside of the fuel tank body manufactured by blow molding or the like. When attaching the fuel tank built-in component, it is common to use an elevating device that supports the fuel tank built-in component so that the fuel tank built-in component can be moved up and down, and arrange the fuel tank built-in component at a predetermined position of the mold.
　例えば、特許文献１には、燃料タンク内蔵部品を下側から支持する支持棒と、支持棒を上下にスライドさせるスライド機構とを備えた昇降装置を使用し、支持棒を上側にスライドさせることで、金型の所定位置に燃料タンク内蔵部品を配置する発明が記載されている。 For example, Patent Document 1 uses an elevating device that includes a support rod that supports a fuel tank built-in component from below and a slide mechanism that slides the support rod up and down, and slides the support rod upward. An invention is described in which a fuel tank built-in component is arranged at a predetermined position of a mold.
特開２０１０－７６２９９号公報JP 2010-76299 A
　特許文献１に記載の発明では、燃料タンク内蔵部品の下端部から上端部付近に亘って形成された凹部に支持棒を下側から挿入し、支持棒で燃料タンク内蔵部品の上端部付近を支持している。したがって、金型の所定位置に燃料タンク内蔵部品を配置したときに、支持棒の上端部が金型の中央部付近又はそれよりも上側に達し、昇降ストロークが長くなるため、成形サイクルが長くなるという問題があった。 In the invention described in Patent Document 1, a support rod is inserted from below into a recess formed from the lower end portion of the fuel tank built-in component to the vicinity of the upper end portion, and the vicinity of the upper end portion of the fuel tank built-in component is supported by the support rod. is doing. Therefore, when the fuel tank built-in component is arranged at a predetermined position of the mold, the upper end of the support rod reaches near the center of the mold or above the mold, and the lifting stroke becomes longer, so the molding cycle becomes longer. There was a problem.
　本発明は、このような観点から創案されたものであり、成形サイクルを短縮することができる燃料タンク内蔵部品及び燃料タンク内蔵部品の取付方法を提供することを課題とする。 The present invention was created from such a viewpoint, and an object of the present invention is to provide a fuel tank built-in component and a method for mounting the fuel tank built-in component that can shorten the molding cycle.
　このような課題を解決するために、本発明は、燃料タンク本体の成形時に、離間した一対の成形型の間に挿入されるとともに前記燃料タンク本体の内部に取り付けられる燃料タンク内蔵部品であって、挿入方向の後側の端部に形成され、昇降装置で支持される被支持部を備えており、前記被支持部は、前記昇降装置による支持をガイドする支持ガイド部と、前記燃料タンク本体に貯留される燃料の揺動を抑制する揺動抑制部とを有していることを特徴とする。なお、燃料タンク内蔵部品とは、ブラケット、バルブ、ポンプ、波消し部材等の燃料タンク本体の内部に取り付けられる部品をいう。 In order to solve such a problem, the present invention provides a fuel tank built-in component that is inserted between a pair of spaced apart molds and molded inside the fuel tank body when the fuel tank body is molded. A support portion formed at a rear end portion in the insertion direction and supported by an elevating device, the supported portion supporting a support by the elevating device, and the fuel tank body And a rocking suppression portion that suppresses rocking of the fuel stored in the tank. The fuel tank built-in parts refer to parts attached to the inside of the fuel tank body such as brackets, valves, pumps, wave eliminating members and the like.
　本発明によれば、被支持部が燃料タンク内蔵部品の挿入方向の後側の端部に形成されるため、昇降装置で燃料タンク内蔵部品の挿入方向の後側の端部を支持することができる。これにより、昇降ストロークが短くなるため、成形サイクルを短縮することができる。
　また、本発明によれば、被支持部が支持ガイド機能と燃料揺動抑制機能とを併有するため、燃料揺動抑制部材を別途設ける必要がない。これにより、燃料タンク内蔵部品の数を低減し、コストダウンを図ることができる。 According to the present invention, since the supported portion is formed at the rear end of the fuel tank built-in component in the insertion direction, the lifting device can support the rear end of the fuel tank built-in component in the insertion direction. it can. Thereby, since a raising / lowering stroke becomes short, a shaping | molding cycle can be shortened.
Further, according to the present invention, since the supported portion has both the support guide function and the fuel fluctuation suppression function, it is not necessary to separately provide a fuel fluctuation suppression member. Thereby, the number of fuel tank built-in parts can be reduced and cost reduction can be aimed at.
　また、前記支持ガイド部は、相互に対向する一対の基部を含んで構成されており、一対の前記基部の向かい合う内側面は、前記挿入方向の後側の端部に位置するほど相互に遠ざかるように傾斜しており、一対の前記内側面は、前記昇降装置に設けられた基部側支持部材にそれぞれ当接支持されることが好ましい。 The support guide portion includes a pair of base portions facing each other, and the inner side surfaces of the pair of base portions facing each other are located farther from each other as they are positioned at the rear end portion in the insertion direction. Preferably, the pair of inner side surfaces are in contact with and supported by a base side support member provided in the lifting device.
　かかる構成によれば、一対の基部の内側面の間隔が挿入方向の後側の端部に位置するほど広がっているため、昇降装置に設けられた基部側支持部材を一対の内側面の間に挿脱しやすくなる。これにより、昇降装置に対する燃料タンク内蔵部品の設置作業や取外作業を迅速に行うことができる。 According to such a configuration, the distance between the inner side surfaces of the pair of base portions increases as the distance between the inner side surfaces of the pair of base portions increases, so that the base side support member provided in the lifting device is interposed between the pair of inner side surfaces. Easy to insert and remove. Thereby, the installation operation | work of the fuel tank built-in component with respect to an raising / lowering device and the removal operation | work can be performed rapidly.
　また、前記揺動抑制部は、板状を呈し、一対の前記基部同士を連結するとともに相互に離隔して複数設けられ、前記挿入方向の後側の端部に位置するものほど幅狭になっており、各前記揺動抑制部の板幅方向に沿った両端部は、昇降装置に設けられた揺動抑制部側支持部材にそれぞれ当接支持されることが好ましい。 In addition, the swing suppression portion has a plate shape, and a plurality of the base portions are connected to each other and spaced apart from each other, and the portion located at the rear end portion in the insertion direction becomes narrower. In addition, it is preferable that both end portions along the plate width direction of each of the swing suppression portions are respectively supported by a swing suppression portion side support member provided in the lifting device.
　かかる構成によれば、揺動抑制部が挿入方向の後側の端部に位置するものほど幅狭になっているため、昇降装置に設けられた揺動抑制部側支持部材の間に揺動抑制部を挿脱しやすくなる。これにより、昇降装置に対する燃料タンク内蔵部品の設置作業や取外作業を迅速に行うことができる。 According to this configuration, since the swing suppression portion is narrower as it is located at the rear end of the insertion direction, the swing suppression portion is supported between the swing suppression portion side support members provided in the lifting device. It becomes easy to insert and remove the suppressing portion. Thereby, the installation operation | work of the fuel tank built-in component with respect to an raising / lowering device and the removal operation | work can be performed rapidly.
　また、本発明は、燃料タンク本体の成形時に、離間した一対の成形型の間に下側から挿入し前記燃料タンク本体の内部に燃料タンク内蔵部品を取り付ける燃料タンク内蔵部品の取付方法であって、下端部に被支持部が形成された燃料タンク内蔵部品を用意するとともに、前記燃料タンク内蔵部品を着脱自在かつ昇降自在に支持する昇降装置を用意する用意工程と、前記燃料タンク内蔵部品を昇降装置に設置する設置工程と、を含み、前記用意工程では、前記被支持部に前記昇降装置による支持をガイドする支持ガイド部を形成し、前記設置工程では、前記昇降装置で前記支持ガイド部を下側から支持することを特徴とする。 Further, the present invention is a method for mounting a fuel tank built-in component that is inserted from a lower side between a pair of spaced apart molds when the fuel tank main body is molded, and the fuel tank built-in component is mounted inside the fuel tank main body. Preparing a fuel tank built-in component having a supported portion formed at the lower end, and preparing a lifting device for detachably supporting the fuel tank built-in component so as to be movable up and down; and raising and lowering the fuel tank built-in component In the preparation step, a support guide portion for guiding the support by the lifting device is formed in the supported portion, and in the installation step, the support guide portion is mounted by the lifting device. It is characterized by being supported from below.
　本発明によれば、被支持部が燃料タンク内蔵部品の下端部に形成されるため、昇降装置で燃料タンク内蔵部品の下端部を支持することができる。これにより、昇降ストロークが短くなるため、成形サイクルを短縮することができる。 According to the present invention, since the supported portion is formed at the lower end portion of the fuel tank built-in component, the lifting device can support the lower end portion of the fuel tank built-in component. Thereby, since a raising / lowering stroke becomes short, a shaping | molding cycle can be shortened.
