Description

本発明は、インクジェットプリンタ・プロッタなどの描画装置に関し、特に、大型のプリンタ・プロッタなどの描画装置の脚体構造に関する。   The present invention relates to a drawing apparatus such as an ink jet printer / plotter, and more particularly to a leg structure of a drawing apparatus such as a large printer / plotter.

A1やA0の用紙対応のプリンタでは、強度の点で、プリンタ本体の重量があまり問題にならない。そのため、従来の此の種のプリンタでは、比較的簡単な構造でプリンタ本体を支えている(例えば特許文献1及び特許文献2参照)。
特開2001−171204号公報(第1ページ、第1図) 特開2003−182119号公報(第1ページ、第1図)
In a printer that supports A1 and A0 paper, the weight of the printer body is not a problem in terms of strength. Therefore, this type of conventional printer supports the printer body with a relatively simple structure (see, for example, Patent Document 1 and Patent Document 2).
JP 2001-171204 A (first page, FIG. 1) JP2003-182119A (first page, FIG. 1)

2mを越える用紙幅対応の大型のプリンタ・プロッタにおいては、装置の幅が長くなり、また装置の重量も重くなるとともに、装置本体を支える脚の間隔が非常に大きくなるため、左右の脚の間において、装置本体が撓むことが起きる。その装置本体の撓みは、特にインクジェット等の印字機構を使用した場合は、装置の性格上、非常に問題が大きく、印字精度などに重大な影響が出る恐れがある。   In a large printer / plotter that supports a paper width exceeding 2 m, the width of the device becomes longer, the weight of the device becomes heavier, and the distance between the legs that support the device body becomes very large. In this case, the apparatus main body is bent. The deflection of the main body of the apparatus is extremely problematic due to the characteristics of the apparatus, particularly when a printing mechanism such as an ink jet is used, and there is a possibility that the printing accuracy may be seriously affected.

装置本体の撓みを無くすために、装置本体の機体を構成する部材を太くすることが考えられるが、そのようにすると装置本体の重量が更に重くなり、また、脚にかかる負担も大きくなり脚を強固に作らなければならなくなる。しかし、装置の移動、搬送などの利便性から重たいものよりは軽い方が良いことは当然であり、その兼ね合いは非常に難しいものがある。また、通常の脚の構造でも、ある程度の、上からの荷重に対しては強い構造をもつが、横方向の力にはあまり強度がでないという問題点もある。
本発明は上記問題点を解決することを目的とするものである。
In order to eliminate the bending of the device body, it is conceivable to increase the thickness of the members constituting the machine body of the device body. However, if this is done, the weight of the device body will become heavier, and the load on the legs will also increase. It must be made firmly. However, it is a matter of course that the lighter is better than the heavy one because of the convenience of moving and transporting the apparatus, and the trade-off is very difficult. In addition, a normal leg structure has a structure that is strong against a certain amount of load from the top, but there is also a problem that the lateral force is not very strong.
The present invention aims to solve the above problems.

上記目的を達成するため本発明は、機体に描画機構が支持された描画装置本体と、該描画装置本体を床面から所定の高さに保持する該描画装置本体の左右に配設された脚体とを備えた描画装置において、左右の脚体間に床面に対して略水平に梁材を架設し、該梁材に斜め梁材を連結し、これら梁材によって前記脚体間にトラス構造体を形成したものである。
また本発明は、前記梁材は、左右の脚体の下部間に架設された下部梁材と左右の脚体の上部間に架設された上部梁材とからなり、該上部梁材と前記描画装置本体の下面との間に1又は複数の高さ調整機構が配置されていることを特徴とするものである。
また本発明は、前記左右の脚体を中空構造とし、該脚体内に部品またはインクタンク等の収納部を形成したものである。
また本発明は、前記トラス構造体を複数の三角形を備えた構造としたものである。
また本発明は、機体に描画機構が支持された描画装置本体と、該描画装置本体を床面から所定の高さに保持する該描画装置本体の左右に配設された脚体とを備えた描画装置において、左右の脚体間に床面に対して略水平に梁材を架設し、該梁材は、左右の脚体の下部間に架設された下部梁材と左右の脚体の上部間に架設された上部梁材とからなり、前記上部梁材と下部梁材間に斜め梁材を連結し、これら梁材によって前記脚体間に複数の三角形を備えたトラス構造体を形成し、前記上部梁材と前記描画装置本体の下面との間に複数の高さ調整機構を配置したものである。
In order to achieve the above object, the present invention provides a drawing apparatus main body in which a drawing mechanism is supported by a machine body, and legs disposed on the left and right of the drawing apparatus main body that hold the drawing apparatus main body at a predetermined height from the floor surface. In a drawing apparatus comprising a body, a beam member is laid between the left and right legs substantially horizontally with respect to the floor surface, and an oblique beam member is connected to the beam member. A structure is formed.
Further, in the present invention, the beam material includes a lower beam material erected between the lower portions of the left and right legs and an upper beam material erected between the upper portions of the left and right legs, and the upper beam material and the drawing One or more height adjusting mechanisms are arranged between the lower surface of the apparatus main body.
According to the present invention, the left and right legs are hollow, and storage parts such as parts or ink tanks are formed in the legs.
In the present invention, the truss structure has a structure having a plurality of triangles.
The present invention also includes a drawing apparatus main body in which a drawing mechanism is supported by the machine body, and legs disposed on the left and right of the drawing apparatus main body that hold the drawing apparatus main body at a predetermined height from the floor surface. In the drawing apparatus, a beam member is laid between the left and right legs substantially horizontally with respect to the floor surface, and the beam member includes a lower beam member erected between the lower portions of the left and right legs and an upper portion of the left and right legs. The upper beam member is installed between the upper beam member and the lower beam member, and oblique beam members are connected between the upper beam member and the lower beam member to form a truss structure having a plurality of triangles between the legs. A plurality of height adjusting mechanisms are arranged between the upper beam member and the lower surface of the drawing apparatus main body.

本発明は脚体間に配設した斜め梁材によるトラス構造によって脚体の強度を高めたので、装置本体を下向き及び横方向の荷重に対して強固に支持することができるとともに、その撓みも解消できる。また左右の脚体に大きな強度が要求されないので、脚体を中空構造とすることが可能となり、脚体を部品やインクタンク等の収納などに有効利用することができる。   In the present invention, the strength of the leg is enhanced by the truss structure formed by the diagonal beam members disposed between the legs, so that the apparatus main body can be firmly supported against the load in the downward and lateral directions, and the deflection thereof is also achieved. Can be resolved. In addition, since the left and right legs are not required to have high strength, the legs can have a hollow structure, and the legs can be effectively used for storing parts, ink tanks, and the like.

以下に本発明の構成を添付した図面を参照して詳細に説明する。
図1において、符号2は大型のインクジェットプリンタからなる描画装置であり、描画装置本体4と、それを床面から所定の高さに保持する脚部6とから構成されている。前記装置本体4は、長尺状のY軸レール(図示省略)と、該Y軸レールに沿って移動可能なプリントヘッド(図示省略)と、用紙搬送機構と、コントロール部とからなる描画機構を有し、該描画機構は、装置本体4の機体(図示省略)に直接または間接的に支持されている。前記描画装置本体4の描画機構はカバー8によって覆われ、前記用紙搬送機構の構成要素の一つであるプラテン10の一部が描画装置2の正面側に露出している。
Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
In FIG. 1, reference numeral 2 denotes a drawing apparatus composed of a large-sized ink jet printer, which is composed of a drawing apparatus body 4 and legs 6 that hold the drawing apparatus at a predetermined height from the floor surface. The apparatus main body 4 includes a drawing mechanism including a long Y-axis rail (not shown), a print head (not shown) movable along the Y-axis rail, a paper transport mechanism, and a control unit. The drawing mechanism is directly or indirectly supported by a body (not shown) of the apparatus main body 4. The drawing mechanism of the drawing apparatus main body 4 is covered with a cover 8, and a part of the platen 10 that is one of the components of the paper transport mechanism is exposed to the front side of the drawing apparatus 2.

脚部6は、一対の脚体12,14と、脚体12,14間に設けられたトラス構造体16とから構成されている。前記脚体12,14は、描画装置本体4の下面の長手方向の両端近傍に、床面に対して垂直に配置され、各上端が描画装置本体4の機体に固定されている。各脚体12,14の下端は、これらと一体的な足部材18,20を介して、床面上に載置されている。前記脚体12,14は、本実施形態では非中空状の鋼材により構成されている。 The leg portion 6 includes a pair of leg bodies 12 and 14 and a truss structure body 16 provided between the leg bodies 12 and 14. The legs 12 and 14 are arranged in the vicinity of both ends in the longitudinal direction of the lower surface of the drawing apparatus main body 4 so as to be perpendicular to the floor surface, and each upper end is fixed to the body of the drawing apparatus main body 4. The lower ends of the leg bodies 12 and 14 are placed on the floor surface via foot members 18 and 20 integral with them. In the present embodiment, the legs 12 and 14 are made of a non-hollow steel material.

前記トラス構造体16は、床面及び描画装置本体4の下面に対して、水平に延び、両端が前記脚体12,14の上部に架設固定された鉄骨材とこれと一体的な板材とからなる上部梁材22と、床面及び描画装置本体4の下面に対して、水平に延び、両端が前記脚体12,14の下部に架設固定された鉄骨材とこれと一体的な板材からなる下部梁材24と、一対の斜め梁材26,28とを主たる構成要素としている。斜め梁材26,28の各一端は、連結具30,32を介して、下部梁材24の両端に角度を有して固定されている。各他端は、連結具34を介して、上部梁材22の中間部に角度を有して固定されている。 The truss structure 16 extends horizontally with respect to the floor surface and the lower surface of the drawing apparatus main body 4, and includes a steel frame member having both ends erected and fixed on the upper portions of the leg members 12 and 14, and a plate member integral therewith. The upper beam member 22, the floor surface, and the lower surface of the drawing apparatus main body 4, are formed of a steel frame member that extends horizontally and has both ends erected and fixed to the lower portions of the legs 12 and 14, and a plate member that is integral therewith. The lower beam member 24 and a pair of oblique beam members 26 and 28 are main components. One end of each of the oblique beam members 26 and 28 is fixed at an angle to both ends of the lower beam member 24 via the coupling members 30 and 32. Each other end is fixed with an angle to an intermediate portion of the upper beam member 22 via a connector 34.

前記上部梁材22と、前記描画装置本体4の下面の中央との間には高さ調整機構36が配置されている。高さ調整機構36は、上部梁材22に固着された板ナット38と、これに螺合するボルトとからなり、ボルトの突出量は適宜調整可能となっている。前記高さ調整機構36は、斜め梁材26,28と下部梁材24とで形成される三角形の頂部に配置されている。描画装置本体4の下面中央には、その撓みが補正された状態で、上部梁材22を支点として、高さ調整機構36の上端が圧接し、描画装置本体4の中間部を押し上げ、描画装置本体4の撓みを矯正している。 A height adjusting mechanism 36 is disposed between the upper beam member 22 and the center of the lower surface of the drawing apparatus main body 4. The height adjustment mechanism 36 includes a plate nut 38 fixed to the upper beam member 22 and a bolt screwed to the plate nut 38, and the protruding amount of the bolt can be adjusted as appropriate. The height adjusting mechanism 36 is disposed at the top of a triangle formed by the diagonal beam members 26 and 28 and the lower beam member 24. In the center of the lower surface of the drawing apparatus main body 4, the upper end of the height adjustment mechanism 36 is pressed against the upper beam member 22 with the upper beam member 22 as a fulcrum, and the intermediate portion of the drawing apparatus main body 4 is pushed up. The bending of the main body 4 is corrected.

上記した構成において、脚体12,14間のトラス構造体16により、脚部6の下方向の荷重に対する強度及び横方向の荷重に対する強度が増大する。そして脚体の中間部にて描画装置本体を下から支える構造を付加したので描画装置本体4の撓みを解消し、そして、描画装置本体4を安定的に支持することができる。尚、上部梁材22を描画装置本体4の下面に一体的に設けるようにしても良い。   In the above configuration, the truss structure 16 between the legs 12 and 14 increases the strength against the downward load of the leg 6 and the strength against the lateral load. And since the structure which supports a drawing apparatus main body from the bottom is added in the intermediate part of the leg, the bending of the drawing apparatus main body 4 can be eliminated, and the drawing apparatus main body 4 can be supported stably. The upper beam member 22 may be integrally provided on the lower surface of the drawing apparatus body 4.

上記実施形態では、脚体12,14間に、斜め梁材26,28により、1個の三角形を形成したが、斜め梁材40,42,44,46を4本用いることで、図2に示すように、2個の三角形を形成した、より強度の大きなトラス構造体48とすることが可能である。勿論、描画装置本体4の長さに応じて、更に、斜め梁材による三角形を増加させることができる。図2において、上部梁材22には、トラス構造体48の三角形の2つの頂部に対応して、2個の高さ調整機構50,52が配設されている。   In the above embodiment, one triangle is formed between the legs 12 and 14 by the diagonal beam members 26 and 28. However, by using four diagonal beam members 40, 42, 44 and 46, FIG. As shown, a stronger truss structure 48 formed with two triangles is possible. Of course, according to the length of the drawing apparatus main body 4, the triangles formed by the oblique beam members can be further increased. In FIG. 2, two height adjusting mechanisms 50 and 52 are disposed on the upper beam member 22 so as to correspond to the two triangular tops of the truss structure 48.

次に、図3を参照して本発明の他の実施形態について説明する。
54,56は脚体であり、比較的薄い板金によって、断面四角の筒状に構成され、中空の内部に部品またはインクタンク等の収納部が形成されている。脚体54,56の上部は、描画装置本体4の両端に固定され、各下端は、足部材59,60を介して、床面に載置されている。前記脚体54の部品またはインクタンク等の収納部には、コントロール部のプリント基板58が格納されている。
Next, another embodiment of the present invention will be described with reference to FIG.
Reference numerals 54 and 56 denote legs, which are formed by a relatively thin sheet metal into a cylindrical shape with a square cross section, and a storage portion such as a component or an ink tank is formed inside the hollow. Upper portions of the leg bodies 54 and 56 are fixed to both ends of the drawing apparatus main body 4, and lower ends of the leg bodies 54 and 56 are placed on the floor surface via leg members 59 and 60. A printed circuit board 58 of the control unit is stored in a storage unit such as a component of the leg 54 or an ink tank.

また、前記脚体56の部品またはインクタンク等の収納部には、出し入れ自在なキャビネット64,66が設けられ、これらにインクタンク68が格納されている。前記脚体54,56間には、トラス構造体16が配設されている。このトラス構造体16の上部梁材20と下部梁材24には、基板70やその他の所要の装置(図示省略)が取り付けられている。尚、トラス構造体16の梁材に、インク供給システムその他の装置を配設することが可能である。 In addition, cabinets 64 and 66 that can be taken in and out are provided in a storage portion such as a part of the leg body 56 or an ink tank, and an ink tank 68 is stored in these cabinets. A truss structure 16 is disposed between the legs 54 and 56.
