Description

本発明は、ワークの背面側に形成されたリブを挟持して該ワークを搬送するワーク搬送用治具及びこれにワークを固定させるためのワーククランパに関する。   The present invention relates to a workpiece conveying jig for conveying a workpiece while holding a rib formed on the back side of the workpiece, and a workpiece clamper for fixing the workpiece to the workpiece.

水圧転写は、印刷模様が施された水溶性フィルムを浮かべた水面にワークを水没させることにより、ワーク表面にその印刷模様を転写する表面装飾技術であり、樹脂製品に木目、皮革、天然石等の模様を施して高級感を付与することが行われている。   Water pressure transfer is a surface decoration technology that transfers the printed pattern onto the surface of the work by submerging the work in a water surface with a water-soluble film with a printed pattern on it. Resin products such as wood grain, leather, natural stone, etc. A pattern is given to give a sense of quality.

この場合、ワークは、水圧転写槽上を走行するコンベアや、所定の軌跡でアームを動かすロボットにより搬送されながら水没される。しかし、ワークをコンベアに直接固定したり、ロボットのアームに固定することはできないので、搬送用治具に固定して、その治具をコンベアやロボットで搬送しながら水圧転写を行っている。   In this case, the workpiece is submerged while being conveyed by a conveyor that runs on the hydraulic transfer tank or a robot that moves the arm along a predetermined locus. However, since the workpiece cannot be fixed directly to the conveyor or to the arm of the robot, it is fixed to a transfer jig, and hydraulic transfer is performed while the jig is transferred by the conveyor or robot.

樹脂製品には、成型加工上、装飾を施さない裏面側にリブが形成されているので、搬送用治具は、そのリブを挟持するクリップをリブの位置に対応させて所定間隔で設けて形成してある。
そして、水圧転写槽まで搬送されてきたワークを作業者が水圧転写用の搬送用治具に取り付けた後、着荷位置でコンベアやロボットに着荷され、脱荷位置でコンベアやロボットから脱荷された搬送用治具から作業者がワークを外しているのが実情である。
この場合に、作業者の負担を軽減するためにワークを装着し易く、しかも、水圧転写中に脱落し難いクランパが要求されるが、最も重要視されるのは後者である。 In resin products, ribs are formed on the back side that is not decorated for molding, so the conveying jig is formed by providing clips that sandwich the ribs at predetermined intervals corresponding to the positions of the ribs. It is.
Then, after the work that had been transported to the hydraulic transfer tank was attached to the transport jig for hydraulic transfer, it was loaded onto the conveyor or robot at the loading position, and unloaded from the conveyor or robot at the unloading position. The actual situation is that the operator removes the workpiece from the conveying jig.
In this case, a clamper is required that is easy to mount a work to reduce the burden on the operator and that does not easily fall off during hydraulic transfer, but the latter is the most important.

図３はこのような従来の搬送用治具５１を示し、コンベアやロボットで搬送されるベース５２にワークＷの背面に形成されるリブＲを挟持するワーククランパ５３が所定間隔で取り付けられている。
ワーククランパ５３は、ベース５２に固定される剛性板５４に可撓性板５５の片端側が重ねられて熔接固定され、剛性板５４と可撓性板５５の間にその自由端側５５ｂから差し込まれるワークＷを可撓性板５５の弾撥力により挟持させるようになっている。
可撓性板５５は折り曲げ形成されて、剛性板５４に当接される先端側部分がワークＷをクランプする挟持部５３ａに形成されている。
ワークＷを挟持部５３ａにスムースに差し込めることができるように、剛性板５４及び可撓性板５５は、挟持部５３ａの先端側が外側に広がって互いに離れるように形成されている。 FIG. 3 shows such a conventional conveying jig 51, and a work clamper 53 for holding a rib R formed on the back surface of the work W is attached to a base 52 conveyed by a conveyor or a robot at a predetermined interval. .
The work clamper 53 is welded and fixed by superimposing one end of a flexible plate 55 on a rigid plate 54 fixed to the base 52, and is inserted between the rigid plate 54 and the flexible plate 55 from its free end side 55b. The workpiece W is held by the elastic force of the flexible plate 55.
The flexible plate 55 is formed by bending, and the tip end side portion that comes into contact with the rigid plate 54 is formed in a clamping portion 53 a that clamps the workpiece W.
The rigid plate 54 and the flexible plate 55 are formed so that the front end side of the clamping portion 53a spreads outward and is separated from each other so that the workpiece W can be smoothly inserted into the clamping portion 53a.

また、挟持部５３ａに差し込まれたワークＷに対し、可撓性板５５の先願側でワークＷを挟持することができるように、可撓性板５５は、固定端５５ａから外側に広がるように折り曲げられた後、内側に折り曲げられて懐部５６を形成している。
これにより、その懐部５６の入る厚さまでならワークＷの厚さに関係なく、可撓性板５５の先端側がワークＷに当接されて、ワークＷは挟持される。 Further, the flexible plate 55 extends outward from the fixed end 55a so that the workpiece W can be clamped on the prior application side of the flexible plate 55 with respect to the workpiece W inserted into the clamping portion 53a. After being folded, the inner portion 56 is folded to the inside.
As a result, the tip end side of the flexible plate 55 is brought into contact with the workpiece W regardless of the thickness of the workpiece W up to the thickness where the pocket portion 56 enters, and the workpiece W is clamped.

しかしながら、最近では、水圧転写槽内に水流を生じさせ、その下流側から上流側に向ってワークを移動させながら水圧転写することが行われ、水圧転写を行うときのワークＷの相対速度が速くなっていることから、その水流抵抗も大きくなり、実験では、ワークＷが水圧転写槽内で脱落することもあった。
このため、可撓性板５５として、より厚いものを用いてバネ強度（剛性）を高くしたワーククランプを試作してみたが、治具５１へのワークＷの着脱が困難になり、その割にはクランプ強度にそれほど大きな変化はないことが判明した。
しかも、厚い板バネを複数回折り曲げて形成しなければ成らないことから製造コストも嵩むという問題があった。 However, recently, a water flow is generated in the water pressure transfer tank, and the water pressure transfer is performed while moving the work from the downstream side toward the upstream side, and the relative speed of the work W when performing the water pressure transfer is high. Therefore, the water flow resistance is increased, and in the experiment, the workpiece W may fall off in the hydraulic transfer tank.
For this reason, a prototype of a work clamp having a higher spring strength (rigidity) using a thicker flexible plate 55 is used, but it becomes difficult to attach and detach the work W to and from the jig 51. It was found that there was no significant change in clamp strength.
In addition, since a thick leaf spring must be formed by bending a plurality of times, there is a problem that the manufacturing cost increases.

そこで本発明は、製造コストがそれほど嵩むことなく、簡単な構成で、ワークを容易に装着させることができ、しかも、搬送中に外力が作用しても脱落しないようにすることを技術的課題としている。   Therefore, the present invention has a technical problem that a work can be easily mounted with a simple configuration without increasing the manufacturing cost, and is not dropped even if an external force is applied during conveyance. Yes.

この課題を解決するために、本発明は、可撓性板の片端側が剛性板に重ねられて熔接固定され、剛性板と可撓性板の間にその自由端側から差し込まれるワークを前記可撓性板の弾撥力により挟持させるワーククランパであって、前記可撓性板は、その自由端側が内側に鋭角的に折り曲げられ、その頂点から固定端側が自由端を剛性板側に付勢する板バネ部となり、その頂点から自由端までがその先端エッジをワークに喰い込ませる折返部となったフック状カンチレバーに形成され、前記剛性板には、可撓性板の上から前記板バネ部を剛性板側に付勢する補強用平板カンチレバーが熔接固定されたことを特徴としている。   In order to solve this problem, according to the present invention, one end of a flexible plate is overlapped with a rigid plate and fixed by welding, and a workpiece inserted from the free end side between the rigid plate and the flexible plate is inserted into the flexible plate. A work clamper that is clamped by the elastic force of a plate, wherein the flexible plate has its free end side bent acutely inward, and from its apex the fixed end side biases the free end toward the rigid plate side It is formed in a hook-shaped cantilever that becomes a spring part, and the tip edge to the free end is a folded part that bites the tip edge into the workpiece, and the rigid plate has the plate spring part from above the flexible plate. A reinforcing flat plate cantilever for urging the rigid plate is welded and fixed.

本発明のワーククランパによれば、可撓性板の自由端側が内側に鋭角的に折り曲げられてフック状カンチレバーに形成されているので、可撓性板と剛性板の隙間にワークＷを差し込んでいけば、ワークは頂点から自由端に至る折返部のテーパ面に案内されて、可撓性板をその弾撥力に抗して押し広げながら侵入し、先端エッジが当接されて挟持される。
ここで、ワークを抜き取る方向に外力が作用すると、先端エッジが引っ掛かって可撓性板を押し広げる方向に力が作用するので、先端エッジがさらにワークに喰い込んでワークが脱落するのを阻止する。
しかも、補強用カンチレバーにより可撓性板の上から板バネ部が剛性板側に付勢されているので、先端エッジはより強固に喰い込むことになる。
また、可撓性板は先端側を折り曲げるだけで足り、補強用カンチレバーも平板で足り、加工が極めて簡単であるので、熔接回数が多少増えることはあっても製造コストが大幅に嵩むこともない。 According to the work clamper of the present invention, the free end side of the flexible plate is bent acutely inward and formed into a hook-shaped cantilever, so that the workpiece W is inserted into the gap between the flexible plate and the rigid plate. If it goes, the workpiece is guided by the taper surface of the folded part from the apex to the free end, and enters the flexible plate while pushing against the elastic force, and the tip edge is brought into contact with and pinched. .
Here, when an external force acts in the direction of extracting the workpiece, the tip edge is caught and the force acts in the direction of spreading the flexible plate, so that the tip edge further bites into the workpiece and prevents the workpiece from falling off. .
In addition, since the leaf spring portion is biased toward the rigid plate from the top of the flexible plate by the reinforcing cantilever, the leading edge bites more firmly.
In addition, the flexible plate only needs to be bent at the front end, and the reinforcing cantilever is sufficient as a flat plate. The processing is extremely simple, so the manufacturing cost does not increase significantly even if the number of weldings increases slightly. .

本例では、製造コストがそれほど嵩むことなく、簡単な構成で、ワークを容易に装着させることができ、しかも、水圧転写中に脱落しないようにするという目的を、可撓性板の形状を改良し、且つ、補強材を設けることにより達成した。   In this example, the shape of the flexible plate is improved for the purpose of making it possible to easily mount the workpiece with a simple configuration without increasing the manufacturing cost, and to prevent it from falling off during hydraulic transfer. And by providing a reinforcing material.

図１は本発明に係るワーク搬送用治具を示す説明図、図２は本発明に係るワーククランパを示す説明図である。   FIG. 1 is an explanatory view showing a workpiece conveying jig according to the present invention, and FIG. 2 is an explanatory view showing a work clamper according to the present invention.

図１に示すワーク搬送用治具１は、ワークＷの背面側に形成されたリブＲを挟持して該ワークＷを搬送するもので、コンベアやロボット（図示せず）で搬送されるベースＢに、前記リブＲを挟持するワーククランパＣがそのリブＲと対応する位置に所定間隔で取り付けられて成る。   A workpiece conveying jig 1 shown in FIG. 1 conveys the workpiece W while sandwiching a rib R formed on the back side of the workpiece W. A base B conveyed by a conveyor or a robot (not shown). In addition, a work clamper C that holds the rib R is attached to a position corresponding to the rib R at a predetermined interval.

ワーククランパＣは、ベースＢに固定される剛性板２に可撓性板３の片端側が重ねられて熔接固定され、剛性板２と可撓性板３の間にその自由端３ａ側から差し込まれるワークＷを可撓性板３の弾撥力により挟持させるようになっている。
剛性板２は可撓性板３より曲げ剛性（ＥＩ値）の高い金属材料が使用され、同質材料でも厚さ×幅が大きなものを選定することにより剛性を高くしている。
なお、剛性板２の大きさはワークＷによって様々であるが、例えば幅７ｃｍ×高さ１５ｃｍ×厚さ４ｍｍのステンレス板が用いられている。 The work clamper C is welded and fixed by superimposing one end of the flexible plate 3 on the rigid plate 2 fixed to the base B, and inserted between the rigid plate 2 and the flexible plate 3 from the free end 3a side. The workpiece W is clamped by the elastic force of the flexible plate 3.
The rigid plate 2 is made of a metal material having a higher bending rigidity (EI value) than that of the flexible plate 3, and the rigidity is increased by selecting a homogeneous material having a large thickness × width.
The size of the rigid plate 2 varies depending on the workpiece W. For example, a stainless plate having a width of 7 cm, a height of 15 cm, and a thickness of 4 mm is used.

また、可撓性板３は、剛性板２より曲げ剛性（ＥＩ値）の低い金属材料が使用され、例えば幅５ｃｍ×高さ１０ｃｍ×厚さ１.５ｍｍのステンレス板が用いられている。
そして、自由端３ａ側が内側に鋭角的に折り曲げられ、その頂点３ｂから固定端３ｃ側が自由端３ａを剛性板２側に付勢する板バネ部３ｄとなり、その頂点３ｂから自由端３ａまでがその先端エッジ３ｅをワークＷに喰い込ませる折返部３ｆとなる二つ折りのフック状カンチレバーに形成されている。 The flexible plate 3 is made of a metal material having a bending rigidity (EI value) lower than that of the rigid plate 2, for example, a stainless plate having a width of 5 cm × a height of 10 cm × a thickness of 1.5 mm.
Then, the free end 3a side is bent acutely inward, the apex 3b to the fixed end 3c side becomes a leaf spring portion 3d that urges the free end 3a toward the rigid plate 2, and the apex 3b to the free end 3a It is formed in a half-folded hook-shaped cantilever that becomes a folded portion 3 f that bites the leading edge 3 e into the workpiece W.

可撓性板３がフック状に折曲形成されていることから、自由端３ａの先端エッジ３ｅは頂点３ｂよりも固定端３ｃ側に位置し、自由端３ａから頂点３ｂに至る折返部３ｆが自由端３ａ側から見て外側に広がるテーパ面となっており、剛性板２もその先端部２ａが外側に広るテーパ面となっている。
したがって、剛性板２の先端部２ａと可撓性板３の折返部３ｆが互いに離れる方向に広がって形成され、この部分がワークＷを剛性板２と可撓性板３の間にスムースに導く案内部となっている。
また、折返部３ｆがテーパ面となっていることから、ワークＷを差し込んだ状態で自由端３ａを拡大してみると、可撓性板３の板厚部分の角部である先端エッジ３ｅがリブＲに喰い込むように当接されることがわかる。 Since the flexible plate 3 is bent in a hook shape, the leading edge 3e of the free end 3a is located closer to the fixed end 3c than the vertex 3b, and the folded portion 3f extending from the free end 3a to the vertex 3b is formed. The rigid plate 2 has a tapered surface that widens outward, as seen from the free end 3a side.
Accordingly, the distal end portion 2 a of the rigid plate 2 and the folded portion 3 f of the flexible plate 3 are formed so as to be separated from each other, and this portion smoothly guides the workpiece W between the rigid plate 2 and the flexible plate 3. It is a guide.
Further, since the folded portion 3f has a tapered surface, when the free end 3a is enlarged with the workpiece W inserted, the leading edge 3e, which is a corner of the thickness portion of the flexible plate 3, is formed. It turns out that it contacts so that it may bite into rib R.

さらに、剛性板２には、可撓性板３の上からその板バネ部３ｄを剛性板２側に付勢する補強用カンチレバー４が熔接固定されている。本例では、このは可撓性板３と同じ材質、同じ板厚のものが用いられている。
そして、板バネ部３ｄを剛性板２側に付勢していることから、頂点３ｂが剛性板２側に付勢され、その結果、先端エッジ３ｅが剛性板２に強固に押し当てられ、ワークＷが差し込まれたときに、先端エッジ３ｅをワークＷに確実に喰い込ませることができるようになっている。 Further, a reinforcing cantilever 4 for urging the plate spring portion 3d toward the rigid plate 2 from above the flexible plate 3 is welded and fixed to the rigid plate 2. In the present example, the same material and the same thickness as the flexible plate 3 are used.
And since the leaf | plate spring part 3d is urged | biased to the rigid board 2 side, the vertex 3b is urged | biased to the rigid board 2 side, As a result, the front-end | tip edge 3e is firmly pressed against the rigid board 2, and a workpiece | work When W is inserted, the leading edge 3e can be securely bited into the workpiece W.

このように、ワーククランパＣは、先端のみ外側に広げられた平板状の剛性板２と、フック状に二つ折りされた可撓性板３と、平板状の補強用平板カンチレバー４を順に熔接すればたり、製造コストを押えることができる。
また、可撓性板３は二つ折に形成するだけで足り、補強用カンチレバー４も平板で足り、加工が極めて簡単であるので、熔接回数が多少増えることはあっても製造コストが大幅に嵩むこともない。
さらに、これらを金属板等で製造する場合に、その大きさから廃材等を利用して製造することができ、より製造コストを低減することができる。 In this way, the work clamper C is formed by welding the flat plate-like rigid plate 2 that is spread outward only at the tip, the flexible plate 3 folded in a hook shape, and the flat plate-shaped reinforcing plate cantilever 4 in order. In short, the manufacturing cost can be suppressed.
Further, it is sufficient to form the flexible plate 3 in two folds, and the reinforcing cantilever 4 is also sufficient as a flat plate. Since the processing is extremely simple, the manufacturing cost is greatly increased even if the number of weldings is slightly increased. There is nothing.
Furthermore, when manufacturing these with a metal plate etc., it can manufacture using a waste material etc. from the magnitude | size, and can reduce manufacturing cost more.

以上が本発明の一例構成であって、次にその作用について説明する。
ワークＷを装着するときは、図２（ａ）に示すように、剛性板２の先端部２ａと可撓性板３の折返部３ｆのテーパ面に沿ってリブＲをワーククランパＣの剛性板２と可撓性板３の間に差し込んで行く。
このとき、リブＲは剛性板２の先端部２ａと可撓性板３の折返部３ｆのテーパ面に案内されるので、その間にスムースに差し込むことができる。
そして、図２（ｂ）に示すように、リブＲ先端が可撓性板３の折返部３ｆを押し広げることにより、板バネ部３ｄが固定端３ｃを中心として外側に撓み、折返部３ｆが頂点３ｂを中心として折り畳まれるように撓み、その弾撥力により先端エッジ３ｅがリブＲに食い込むように挟持される。 The above is an example configuration of the present invention, and its operation will be described next.
When mounting the workpiece W, as shown in FIG. 2A, the rib R is connected to the rigid plate of the work clamper C along the tapered surfaces of the tip portion 2a of the rigid plate 2 and the folded portion 3f of the flexible plate 3. 2 and the flexible plate 3 are inserted.
At this time, since the rib R is guided by the tapered surface of the tip 2a of the rigid plate 2 and the folded portion 3f of the flexible plate 3, it can be smoothly inserted between them.
Then, as shown in FIG. 2 (b), the tip of the rib R pushes the folded portion 3f of the flexible plate 3 so that the leaf spring portion 3d bends outward about the fixed end 3c, and the folded portion 3f The tip 3b is bent so as to be folded around the vertex 3b, and the tip edge 3e is pinched so as to bite into the rib R by its elastic force.

次いで、搬送用治具１に取り付けられている全てのワーククランパＣにリブＲを挟持させた状態で、その治具１をロボットアームに持たせて水圧転写槽（図示せず）内にワークＷを水没させてこれを引き上げる。
この間、ワークＷが水流などによる抵抗を受けて、クランパＣに挟持されているリブＲが抜ける方向に外力が作用すると、リブＲに喰い込むように当接されている先端エッジ３ｅが抜取方向に移動させられ、その結果、折返部３ｆの頂点３ｄにおける折畳角が広げられて、頂点３ｄが外側に移動することとなる。 Next, in a state where the ribs R are held between all the work clampers C attached to the transfer jig 1, the jig 1 is held by the robot arm and the work W is placed in a hydraulic transfer tank (not shown). And submerge it up.
During this time, when the workpiece W receives resistance due to a water flow or the like and an external force acts in a direction in which the rib R sandwiched by the clamper C is pulled out, the leading edge 3e that is in contact with the rib R is pulled in the extraction direction. As a result, the folding angle at the vertex 3d of the folding portion 3f is widened, and the vertex 3d moves outward.

即ち、リブＲを抜こうとすると、図２（ｂ）鎖線で示すように、板バネ部３ｄと補強用平板カンチレバー４の弾撥力に抗してこれらを撓ませながら頂点３ｂを外側に移動させなければならないだけでなく、二つ折りされた可撓性板３の弾撥力に抗して折返部３ｆの折畳角を押し広げていかなければならない。
そして、これらが撓めば撓むほどその弾撥力が強くなって、先端エッジ３ｅはより強固にリブＲに喰い込むので、リブＲを容易に抜き取ることはできない。
したがって、ワークＷが水流などの抵抗を受けてリブＲがクランパＣから抜ける方向に外力が作用しても、先端エッジ３ｅがリブＲに喰い込むので、ワークＷが簡単に脱落することはない。 That is, when the rib R is removed, the vertex 3b is moved outward while bending the plate spring portion 3d and the reinforcing flat plate cantilever 4 against the elastic force as shown by the chain line in FIG. 2 (b). In addition to this, the folding angle of the folded portion 3f must be increased against the elastic force of the flexible plate 3 folded in half.
And if these are bent, the elastic force will become so strong that it will be bent, and since the front-end edge 3e will bite into the rib R more firmly, the rib R cannot be extracted easily.
Therefore, even if an external force is applied in a direction in which the workpiece W receives resistance such as a water flow and the rib R is removed from the clamper C, the tip edge 3e bites into the rib R, so that the workpiece W does not easily fall off.

以上述べたように、本発明は、コンベアやロボットに直接取り付けられたないワークを搬送したり、搬送しながら何らかの処理を施す場合に、そのワークを比較的簡単に且つ確実にクランプする用途に適用することができる。   As described above, the present invention can be applied to applications in which workpieces that are not directly attached to a conveyor or a robot are transported, or when the workpiece is subjected to some processing while being transported, relatively easily and securely clamped. can do.
