【発明の属する技術分野】
この発明は、往復直線移動する可動体に取付けられた各種の駆動部材に対して電力、信号、エアー又は油等の流体(以下、制御信号手段という)を伝達するホース或いはケーブル(以下、制御信号伝達手段という)を屈曲案内するケーブルチェーンに関する。
【0002】
【発明が解決しようとする課題】
各種の機械においては、往復直線移動する可動体に取付けられた駆動部材に対して電力、制御信号、流体等の制御信号手段を供給するため、両者間に制御信号伝達手段を接続しているが、該制御信号伝達手段自体、少なくとも可動体の最大移動距離の長さからなるため、可動体の移動に伴って引きずられたり、屈曲したりして破損するおそれがあり、可動体に対して制御信号手段を確実に伝達できなかった。
【0003】
この欠点を解決するため、例えば特開平2−186146号公報に示すように、一端部に軸部及び他端部に軸支部を有した一対のリンクプレートと、該リンクプレートの上下に設けた案内板とを枠形に形成してなる複数のガイド部材を、軸支部に軸部を係合させて屈曲可能に連結すると共に前記案内板は夫々可撓性を有する舌片を、前後方向の少なくとも一方に突設すると共に前記舌片が前記案内板間を閉鎖するようにしたケーブルチェーンが各種開発されているが、この種のケーブルチェーンは、可動体の移動距離に応じた多数のガイド部材相互を、一方のリンクプレートにおける軸部を他方のリンクプレートにおける軸支部に係合させて長尺状に連結した後に一対のリンクプレート間に制御信号伝達手段を収容させると共に上端部を閉鎖部材により閉鎖しなければならなかった。
【0004】
このため、ガイド部材における連結構造が複雑化してその製作コストが高くなると共にガイド部材相互の連結作業に多くの時間がかかり、取付け作業性が悪かった。
【0005】
又、上記した構造のケーブルチェーンはその屈曲に伴ってチェーン単位部材の端部相互が磨耗して樹脂粉が発生していた。このため、食品を加工処理したり、電子部品を製造するクリーンルームに設置される各種加工機の可動体に接続される制御信号伝達手段を屈曲案内するためのケーブルチェーンとしては使用できなかった。
【0006】
本発明は、上記した従来の欠点を解決するために発明されたものであり、その課題とするところは、チェーン単位部材の構造を簡易化して低コスト化することができるケーブルチェーンを提供することにある。
【0007】
又、本発明の他の課題は、チェーン単位部材相互の連結作業を簡易化して取付け作業を短時間に行うことができるケーブルチェーンを提供することにある。
【0008】
更に、本発明の他の課題は、チェーン単位部材相互の磨耗による樹脂粉等の発生を防止することができるケーブルチェーンを提供することにある。
【0009】
【課題を解決するための手段】
本発明の請求項1は、所定の間隔をおいて相対する一対の側板の下部を連結する支持板及び一対の側板の上部に、開口部を有した上面板を一体形成した多数のチェーン単位部材と、隣設するチェーン単位部材相互を屈曲可能に連結するヒンジ特性を有した合成樹脂からなるヒンジ部材とからなることを特徴とする。
【0010】
また、本発明の請求項2は、所定の間隔をおいて相対する一対の側板の下部を連結する支持板を一体形成して連結した多数のチェーン単位部材と、各チェーン単位部材における一対の側板に沿って垂下し、側板に設けられた係合部に係合可能な被係合部を有した垂下板及び垂下板の上部を連結する上面板を有して上部開口を覆う閉鎖部材と、隣設するチェーン単位部材相互を屈曲可能に連結するヒンジ特性を有した合成樹脂からなるヒンジ部材とからなることを特徴とする。
【0013】
【発明の実施の形態】
以下、本発明の実施の形態を図に従って説明する。
【0014】
実施の形態1
図1〜図3において、ケーブルチェーン1は多数のチェーン単位部材3相互を、ヒンジ部材5により連結した構造からなる。
【0015】
各チェーン単位部材3はポリプロピレン、ポリアミド樹脂、塩化ビニール樹脂等の合成樹脂により内部に中空部を有した正面がほぼロ字形に一体成形されている。チェーン単位部材3の正面形状はこの形状に限定されるものでないことは勿論である。
【0016】
各チェーン単位部材3の支持板7は連結直交方向が、連結方向に対して長尺状からなり、該支持板7の上面全体には凹所9が形成され、該凹所9の前後側及び中央部には複数(図示のものは3個)の係合孔11が連結直交方向に対して等間隔に形成されている。各係合孔11は上部に小径部11a及び下部に大径部11bを有した形状に形成されている。
【0017】
各支持板7の連結直交方向両端部には脚部13が所定の幅で垂下するように一体成形されると共に相対する一対の側壁部15が所定の高さで起立するように一体成形され、各側壁部15の上部には上面板17が支持板7と平行状に一体成形されている。そして各上面板17には連結方向(或いは連結直交方向)に対して所定の角度で傾斜する開口部17aが形成されている。
【0018】
各チェーン単位部材3は夫々の開口部17aの傾斜方向が互い違いとなるように配列した状態でヒンジ部材5により連結される。該ヒンジ部材5はポリプロピレン樹脂、ポリアミド樹脂等のようにヒンジ特性に優れた合成樹脂からなり、支持板7の凹所9に挿嵌可能な厚さ及び幅で、複数のチェーン単位部材3に亘る連結方向長さからなる。そしてヒンジ部材5の底面には各係合孔11に係合する係合軸部19が一体形成されている。夫々の係合軸部19の先端部には大径部11bに係合する大径頭部19aが一体形成され、各係合孔11に圧入された際に大径部11bに対する大径頭部19aの係合により抜け止めしている。
【0019】
各チェーン単位部材3間に位置する各ヒンジ部材5には連結直交方向へ延出する逆V字形の溝部5aが形成され、該溝部5aによりヒンジ部材5の屈曲性を良好にしている。該溝部5aはヒンジ部材5の板厚のほぼ1/2以上の深さに形成される。
【0020】
又、ヒンジ部材5としては、予め上記したヒンジ特性を有した合成樹脂により帯状で、底面の係合軸部19を有した板状に形成し、ヒンジ部材5の係合軸部19を各チェーン単位部材3の各係合孔11に圧入して固定してチェーン単位部材3相互を連結してもよい。このように予め成形されたヒンジ部材5における係合軸部19の大径頭部19aを弾性変形させながら係合孔11に圧入してチェーン単位部材3相互を連結する場合にあっては、図3に示すように大径頭部19aに先割り溝19bを形成することにより弾性変形を容易化し、固着作業を効率化することができる。
【0021】
更に、夫々の開口部17aが互い違い状となるように配列された複数個のチェーン単位部材3を1ユニット(図示のものは2個のチェーン単位部材3を1ユニットとしている)とし、チェーン単位部材3における任意の係合孔11から上記の合成樹脂を凹所9内に一体成形してもよい。隣設する複数個のチェーン単位部材3に対してヒンジ部材5を二次成形してチェーン単位部材3相互を連結する場合にあっては、凹所9に対するヒンジ部材5の融着及び係合孔11内への充填融着により各チェーン単位部材3相互を強固に連結することができる。
【0022】
尚、チェーン単位部材3に対してヒンジ部材5を上記の合成樹脂により二次成形する場合にあっては、係合孔11としては非貫通状態の穴であってもよい。又、チェーン単位部材3に対してヒンジ部材5を上記の合成樹脂にて二次成形する場合にあっては、該チェーン単位部材3及びヒンジ部材の樹脂の種類によっては相互の融着性が悪い場合もあるが、チェーン単位部材3に対してヒンジ部材5の一部が係合孔11内に充填して係合されるため、相互が非融着状態であってもチェーン単位部材3相互を強固に連結することができる。
【0023】
可動体の取付け側及び供給源の取付け側(何れも図示せず)に位置するチェーン単位部材3は端部側のヒンジ部材5を切除して係合孔11を開放し、開放した係合孔11に固定ねじ(図示せず)を挿通してケーブルチェーン1の各端部を可動体及び供給源に固定すればよい。
【0024】
次に、上記のように形成されたケーブルチェーンの使用例を説明する。
【0025】
図4及び5において、各チェーン単位部材3における上面板17の開口部17aに対し、制御信号伝達手段41を順に湾曲させながら挿入してケーブルチェーン1内に収容させる(図4参照)。この収容状態においては、ケーブルチェーン1内にて制御信号伝達手段41がほぼ直線状態になっているため、波形に連続する夫々の開口部17aから制御信号伝達手段41が抜け出すのを防止し、収容状態を保つことができる。
【0026】
上記のようにケーブルチェーン1及び収容された制御信号伝達手段41の一方端部を制御信号手段の供給源に、又他方端部を可動体に夫々取付ける。そして可動体が往復移動されると、図5に示すようにケーブルチェーン1は可動体の往復移動に追従してヒンジ部材5を溝部5aにて屈曲させることにより各チェーン単位部材3相互が屈曲しながら湾曲し、収容された制御信号伝達手段41を湾曲するように案内している。これにより収容された制御信号伝達手段41の損傷を防止している。
【0027】
このように本実施形態は、各チェーン単位部材3を連結するヒンジ部材5によりケーブルチェーン1を屈曲可能に構成しているため、従来のケーブルチェーンのようにリンクプレートに軸部及び軸支部や回動量規制部を設ける必要がなく、チェーン単位部材自体の構造を簡素化して低コスト化することができる。又、各チェーン単位部材3に対してヒンジ部材5を、ヒンジ特性を有した合成樹脂により二次成形した場合には組立て作業を省くことができる。
【0028】
上記説明は、複数個のチェーン単位部材3に亘る長さの帯状のヒンジ部材5により支持板7の上面を全体的に覆ってチェーン単位部材3相互を連結する構造としたが、図6に示すようにチェーン単位部材3における支持板7の相対する端部に凹所7aを夫々形成し、夫々の凹所7aに挿嵌するようにヒンジ部材5を上記のように圧入したり、又は二次成形してチェーン単位部材3相互を連結する構造であってもよい。
【0029】
実施の形態2
図7及び8において、ケーブルチェーン61はチェーン単位部材63相互をヒンジ部材65により連結した構造からなる。そしてチェーン単位部材63はポリプロピレン、ポリアミド樹脂、塩化ビニール樹脂等からなるベース部67と、該ベース部67の中空部を覆う閉鎖部材としてのカバー69とから構成されている。
【0030】
ベース部67は支持板71の連結直交方向端部に相対する一対の側板73が一体成形された正面がほぼ横向きコ字形からなり、支持板71の連結方向両端部には凹所75が連結直交方向に亘って夫々形成されている。そして各凹所75には複数の穴77が連結直交方向へ所定の間隔をおいて形成されている。尚、ベース板67の形状はこれに限定されるものではないことは勿論である。
【0031】
各側板73の外面中央部には係合部としての軸79が外方へ突出するように夫々一体成形され、各軸79における軸端面の上半分には上方に向って徐々に高さが低くなるテーパ面79aが形成されている。
【0032】
カバー69は各側板73の外面に沿って垂下する一対の垂下板81と、各垂下板81上部を連結する上面板83とを一体成形した、正面がほぼ横向きコ字形に形成されている。そして各垂下板81の下端部内面にはテーパ面81aが軸79のテーパ面79aとほぼ一致するように形成されると共にその中央部には被係合部としての軸支孔81bが軸79に挿嵌するように形成されている。
【0033】
ヒンジ部材65は、例えばポリプロピレン樹脂、ポリアミド樹脂等のようにヒンジ特性を有した合成樹脂により、隣設された各ベース部67における夫々の凹所75に亘る連結方向長さの板状体で、連結方向の各端部下面に軸部65aが穴77に係合するように一体成形されている。該ヒンジ部材5としては、予め上記したヒンジ特性を有した合成樹脂により成形された板状体を、隣設された各ベース部67における凹所75に挿嵌されると共に軸部65aを穴77に圧入したり、圧入接着してベース部67相互を連結するもの、又は隣設された各ベース部67における凹所75に対して上記したヒンジ特性を有した合成樹脂を穴77に充填させながら融着してベース部67相互を連結するものであってもよい。
【0034】
尚、ベース部67相互間に位置するヒンジ部材65には溝部65bが連結直交方向にわたって形成されている。
【0035】
又、予め成形されたヒンジ部材65を使用してベース部67相互を連結する場合、図9に示すように穴77を貫通させると共に支持板71における穴77の周囲に大径部71aを形成する一方、軸部65aの先端部を大径状で先割り形状に成形し、穴77に圧入された軸部65aの先端を大径部71aに係合させることにより抜け止めすればよい。
【0036】
上記のように構成されたケーブルチェーン61による制御信号手段の支持作用については、上記した実施の態様1のケーブルチェーン1と同様であり、その説明を省略する。
【0037】
上記説明は、隣設するチェーン単位部材63における支持板71の一部上面が露出した状態でヒンジ部材65により連結する構造としたが、実施の態様1と同様に複数個のチェーン単位部材63における支持板71の上面の全体に亘るようにヒンジ部材65を取付けてチェーン単位部材63相互を連結する構造であってもよい。
【0038】
【発明の効果】
このため本発明は、チェーン単位部材の構造を簡易化して低コスト化することができる。又、本発明は、チェーン単位部材相互の連結作業を省いて取付け作業を短時間に行うことができる。更に本発明はチェーン単位部材相互の磨耗による樹脂粉等の発生を防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hose or cable (hereinafter, referred to as a control signal) for transmitting a fluid (hereinafter, referred to as control signal means) such as electric power, a signal, air, or oil to various driving members attached to a movable body that reciprocates linearly. Transmission means).
[0002]
[Problems to be solved by the invention]
In various types of machines, control signal transmission means is connected between the two to supply control signal means such as electric power, control signals, and fluid to a driving member attached to a movable body that moves linearly in a reciprocating manner. Since the control signal transmission means itself is at least as long as the maximum moving distance of the movable body, there is a possibility that the control signal transmission means may be dragged or bent with the movement of the movable body and may be damaged. The signaling means could not be transmitted reliably.
[0003]
In order to solve this drawback, for example, as shown in JP-A-2-186146, a pair of link plates having a shaft at one end and a shaft support at the other end, and guides provided above and below the link plate. A plurality of guide members formed in a frame shape with a plate are connected to bendable by engaging a shaft portion with a shaft support portion, and the guide plates each have a flexible tongue piece at least in the front-rear direction. Various types of cable chains have been developed that are protruded on one side and the tongue pieces close between the guide plates. This type of cable chain has a large number of guide members depending on the moving distance of the movable body. After the shaft portion of one link plate is engaged with the shaft support portion of the other link plate and connected in a long shape, the control signal transmitting means is housed between the pair of link plates and the upper end portion is closed. It had to be closed by wood.
[0004]
For this reason, the connecting structure of the guide members is complicated, the manufacturing cost is increased, and the connecting work between the guide members takes much time, and the mounting workability is poor.
[0005]
Further, in the cable chain having the above-described structure, the ends of the chain unit members are worn together with the bending, and resin powder is generated. For this reason, it could not be used as a cable chain for bending and guiding control signal transmission means connected to movable bodies of various processing machines installed in a clean room for processing food or manufacturing electronic components.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional drawbacks, and an object of the present invention is to provide a cable chain capable of simplifying the structure of a chain unit member and reducing the cost. It is in.
[0007]
Another object of the present invention is to provide a cable chain capable of simplifying a connection operation between chain unit members and performing an installation operation in a short time.
[0008]
Still another object of the present invention is to provide a cable chain that can prevent the generation of resin powder and the like due to wear between chain unit members.
[0009]
[Means for Solving the Problems]
Claim 1 of the present invention is a large number of chain unit members integrally formed with a support plate connecting lower portions of a pair of side plates facing each other at a predetermined interval and an upper surface plate having an opening at an upper portion of the pair of side plates. And a hinge member made of a synthetic resin having hinge characteristics for connecting adjacent chain unit members to bend.
[0010]
Further, a second aspect of the present invention provides a plurality of chain unit members integrally formed and connected with a support plate that connects lower portions of a pair of side plates facing each other at a predetermined interval, and a pair of side plates in each chain unit member. A closure member that has an upper surface plate that connects the upper portion of the hanging plate and an upper portion of the hanging plate that has an engaged portion that can be engaged with the engaging portion provided on the side plate and covers the upper opening, And a hinge member made of a synthetic resin having a hinge characteristic for connecting adjacent chain unit members in a bendable manner.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
[0014]
Embodiment 1
1 to 3, a cable chain 1 has a structure in which a number of chain unit members 3 are connected to each other by a hinge member 5.
[0015]
Each of the chain unit members 3 is integrally formed in a substantially rectangular shape with a hollow portion inside in front by a synthetic resin such as polypropylene, polyamide resin, or vinyl chloride resin. Of course, the front shape of the chain unit member 3 is not limited to this shape.
[0016]
The support plate 7 of each chain unit member 3 is elongated in the direction perpendicular to the connection with respect to the connection direction, and a recess 9 is formed on the entire upper surface of the support plate 7. A plurality (three shown) of engagement holes 11 are formed in the center at equal intervals in the direction orthogonal to the connection. Each of the engaging holes 11 is formed in a shape having a small diameter portion 11a at an upper portion and a large diameter portion 11b at a lower portion.
[0017]
At both ends in the connection orthogonal direction of each support plate 7, a leg 13 is integrally formed so as to hang down with a predetermined width, and a pair of opposing side walls 15 are integrally formed so as to stand at a predetermined height, An upper surface plate 17 is integrally formed on the upper portion of each side wall portion 15 in parallel with the support plate 7. Each upper surface plate 17 has an opening 17a that is inclined at a predetermined angle with respect to the connection direction (or the connection orthogonal direction).
[0018]
The chain unit members 3 are connected by the hinge members 5 in a state where the inclination directions of the openings 17a are alternately arranged. The hinge member 5 is made of a synthetic resin having excellent hinge characteristics, such as a polypropylene resin or a polyamide resin, and has a thickness and a width that can be inserted into the recess 9 of the support plate 7 and extends over the plurality of chain unit members 3. Consists of the length in the connecting direction. An engagement shaft portion 19 that engages with each engagement hole 11 is integrally formed on the bottom surface of the hinge member 5. A large-diameter head 19a that engages with the large-diameter portion 11b is integrally formed at a tip end of each of the engagement shaft portions 19, and the large-diameter head against the large-diameter portion 11b when pressed into each of the engagement holes 11 is formed. It is prevented from coming off by the engagement of 19a.
[0019]
Each hinge member 5 located between the chain unit members 3 is formed with an inverted V-shaped groove 5a extending in a direction orthogonal to the connection, and the groove 5a makes the hinge member 5 bendable. The groove 5a is formed at a depth of at least approximately 1 / of the plate thickness of the hinge member 5.
[0020]
In addition, the hinge member 5 is formed in a plate shape having an engagement shaft portion 19 on the bottom surface in a band shape from a synthetic resin having the above-described hinge characteristics in advance, and the engagement shaft portion 19 of the hinge member 5 is formed in each chain. The chain unit members 3 may be connected to each other by press-fitting into the engaging holes 11 of the unit members 3 and fixing them. In the case where the chain unit members 3 are connected to each other by press-fitting into the engagement holes 11 while elastically deforming the large-diameter head 19a of the engagement shaft portion 19 in the hinge member 5 formed in advance as described above, FIG. As shown in FIG. 3, by forming the leading groove 19b in the large diameter head 19a, elastic deformation can be facilitated, and the fixing work can be made more efficient.
[0021]
Further, the plurality of chain unit members 3 arranged such that the openings 17a are alternately arranged are defined as one unit (the illustrated one assumes two chain unit members 3 as one unit), The synthetic resin described above may be integrally formed in the recess 9 from an arbitrary engaging hole 11 in 3. In the case where the hinge members 5 are secondarily formed on a plurality of adjacent chain unit members 3 to connect the chain unit members 3 to each other, the hinge members 5 are fused to the recesses 9 and the engagement holes are formed. The chain unit members 3 can be firmly connected to each other by filling and fusing the inside of the chain unit members 11.
[0022]
In the case where the hinge member 5 is secondarily formed on the chain unit member 3 with the above-described synthetic resin, the engaging hole 11 may be a non-through hole. In the case where the hinge member 5 is secondarily molded with the above-mentioned synthetic resin for the chain unit member 3, mutual fusion is poor depending on the type of resin of the chain unit member 3 and the hinge member. In some cases, since part of the hinge member 5 fills and engages with the chain unit member 3 in the engagement hole 11, the chain unit members 3 can be connected to each other even in a non-fused state. Can be firmly connected.
[0023]
The chain unit member 3 located on the mounting side of the movable body and the mounting side of the supply source (neither is shown) cut off the hinge member 5 on the end side to open the engaging hole 11 and open the engaging hole. 11 may be inserted through a fixing screw (not shown) to fix each end of the cable chain 1 to the movable body and the supply source.
[0024]
Next, an example of use of the cable chain formed as described above will be described.
[0025]
4 and 5, the control signal transmitting means 41 is inserted into the opening 17a of the upper surface plate 17 of each chain unit member 3 while being curved sequentially, and accommodated in the cable chain 1 (see FIG. 4). In this housed state, since the control signal transmitting means 41 is in a substantially linear state in the cable chain 1, the control signal transmitting means 41 is prevented from coming out of each opening 17a continuous with the waveform, and is housed. State can be maintained.
[0026]
As described above, one end of the cable chain 1 and the accommodated control signal transmitting means 41 are attached to the supply source of the control signal means, and the other end is attached to the movable body. When the movable body is reciprocated, as shown in FIG. 5, the cable chain 1 follows the reciprocating movement of the movable body and bends the hinge members 5 in the groove portions 5a, whereby the respective chain unit members 3 bend each other. While being bent, the control signal transmitting means 41 housed therein is guided to be bent. This prevents damage to the accommodated control signal transmitting means 41.
[0027]
As described above, in the present embodiment, since the cable chain 1 is configured to be bendable by the hinge members 5 that connect the chain unit members 3, the shaft portion, the shaft support portion, and the rotation are provided on the link plate as in the conventional cable chain. There is no need to provide a moving amount restricting portion, and the structure of the chain unit member itself can be simplified and the cost can be reduced. Also, when the hinge member 5 for each chain unit member 3 is secondarily formed of a synthetic resin having hinge characteristics, the assembling work can be omitted.
[0028]
In the above description, a structure in which the chain unit members 3 are connected to each other by entirely covering the upper surface of the support plate 7 with the strip-shaped hinge member 5 having a length extending over the plurality of chain unit members 3 is shown in FIG. Recesses 7a are formed at opposite ends of the support plate 7 in the chain unit member 3 as described above, and the hinge members 5 are press-fitted as described above so as to be fitted into the respective recesses 7a, or A structure in which the chain unit members 3 are formed and connected to each other may be used.
[0029]
Embodiment 2
7 and 8, the cable chain 61 has a structure in which chain unit members 63 are connected to each other by hinge members 65. The chain unit member 63 includes a base portion 67 made of polypropylene, polyamide resin, vinyl chloride resin, or the like, and a cover 69 as a closing member that covers a hollow portion of the base portion 67.
[0030]
The base portion 67 has a substantially horizontal U-shape in front in which a pair of side plates 73 facing the connection orthogonal direction end of the support plate 71 are integrally formed, and a concave portion 75 is formed at both ends of the support plate 71 in the connection direction.
