Description
本発明は、樹脂めっき処理前の樹脂成形品のパートライン、即ちばりを研磨する研磨装置に係り、特に凹凸部、角部や曲面部を有する樹脂成形品の周囲に形成されたパートラインを研磨する樹脂成形品のパートライン研磨装置に関するものである。 The present invention relates to a part line of a resin molded product before resin plating treatment, that is, a polishing apparatus for polishing a flash, and in particular, polishing a part line formed around a resin molded product having uneven portions, corner portions and curved surface portions. The present invention relates to a part line polishing apparatus for resin molded products.
樹脂めっきを施す樹脂成形品については、その樹脂めっきした後、クラック割れが生じやすいので、樹脂成形する際に形成された外周部のパートラインを研磨している。また、直接人の手が触れる樹脂成形品については、パートラインを必ず研磨する必要がある。例えば、図５に示すように合成樹脂製の取っ手５１のような樹脂成形品Ｗでは金型成形の際にその接合部に形成されたパートライン５２を研磨していた。 About the resin molded product which resin-plats, since the crack crack is easy to occur after the resin plating, the part line of the outer peripheral part formed when resin-molding is grind | polished. Moreover, it is necessary to polish a part line about the resin molded product which a human hand touches directly. For example, as shown in FIG. 5, in a resin molded product W such as a synthetic resin handle 51, the part line 52 formed at the joint portion is polished at the time of mold forming.
従来は、このような樹脂成形品のパートラインについては、一つ一つの樹脂成形品を手作業で研磨していた。しかし、１個の樹脂成形品の研磨作業に約３０秒から２分以上もかかり研磨処理に長時間を要していた。しかも、手作業の研磨はバラツキが多く、製品の一定品質を維持することが困難であった。 Conventionally, for each part line of such resin molded products, each resin molded product has been manually polished. However, it took about 30 seconds to 2 minutes or more to polish one resin molded product, and the polishing process took a long time. Moreover, manual polishing has many variations, and it has been difficult to maintain a constant quality of the product.
そこで、樹脂成形品を自動研磨する技術が提案されている。例えば、特許文献１の特開２０００−１７６８０７号公報「樹脂成形品のばり取り装置」のように、板状の樹脂成形品の外周部のばりを除去するための樹脂成形品のばり取り方法であって、複数の上記樹脂成形品を積層し、該積層状態の樹脂成形品の外周部に１以上の回転ブラシを接触させた状態で、該回転ブラシを回転駆動しつつ上記積層状態の樹脂成形品と上記回転ブラシとを該樹脂成形品の積層方向に相対移動させて各樹脂成形品の外周部のばりを順次除去することを特徴とする樹脂成形品のばり取り方法が提案されている。 Thus, a technique for automatically polishing a resin molded product has been proposed. For example, as disclosed in Japanese Patent Application Laid-Open No. 2000-176807 “Resin deburring device for resin molded products”, a deburring method for resin molded products for removing deburring on the outer periphery of a plate-shaped resin molded product. A plurality of the resin molded products are stacked, and the one or more rotating brushes are in contact with the outer peripheral portion of the stacked resin molded product, and the rotating brush is rotationally driven while the stacked resin molded products are stacked. There has been proposed a deburring method for a resin molded product, in which the outer peripheral portion of each resin molded product is sequentially removed by relatively moving the product and the rotating brush in the stacking direction of the resin molded product.
また、特許文献１には、積層状態の樹脂成形品を外周部の一部を露出させて積層方向に移動可能に案内支持する第１ガイド部と、上記第１ガイド部上の樹脂成形品の上記露出部分のばりを除去する第１回転ブラシと、上記第１ガイド部に接続して設けられ、上記積層状態の樹脂成形品を外周部の上記第１回転ブラシによるばりの除去が行われない部分を露出させて積層方向に移動可能に案内支持する第２ガイド部と、上記第２ガイド部上の樹脂成形品の上記露出部分のばりを除去する第２回転ブラシと、上記各樹脂成形品の外周部のばりが上記第１及び第２回転ブラシにより順次除去されるように上記積層状態の樹脂成形品を上記第１及び第２ガイド部上で積層方向に移動させる移動機構とを備えていることを特徴とする樹脂成形品のばり取り装置が提案されている。
特許文献１のばり取り方法、ばり取り装置は、スリットを有するような外周形状であっても、樹脂成形品のばり以外の部分に傷を付けることなく、かつ整列状態のままでばりの除去作業を行い、ブロックベルトのブロックのような板状の樹脂成形品の外周部のばりを除去することができる。しかし、合成樹脂製の取っ手のような凹凸部と曲面部を共に有する樹脂成形品の外周部のパートラインは研磨することは困難である。即ち、複雑な形状の樹脂成形品については、そのパートラインを円滑に研磨することができないという問題を有していた。 Even if the deburring method and deburring device of Patent Document 1 have an outer peripheral shape having a slit, the deburring operation is performed without damaging portions other than the flash of the resin molded product and in an aligned state. The flash of the outer peripheral part of a plate-shaped resin molded product like a block of a block belt can be removed. However, it is difficult to polish the part line of the outer peripheral part of the resin molded product having both the uneven part and the curved part such as a handle made of synthetic resin. That is, the resin molded product having a complicated shape has a problem that its part line cannot be polished smoothly.
また、特許文献１のばり取り方法、ばり取り装置では、回転ブラシを採用しているので、樹脂成形品の研磨面に回転方向の傷が付きやすく、その後の樹脂めっきに不具合が生じやすいので、手に触れたときに違和感が生じる製品になりやすいという問題を有していた。 In addition, since the deburring method and deburring apparatus of Patent Document 1 employs a rotating brush, the polishing surface of the resin molded product is easily scratched in the rotation direction, and defects in subsequent resin plating are likely to occur. There was a problem that it was easy to become a product that was uncomfortable when touched.
本発明は、かかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、研磨ベルトと、仕上研磨する板状の研磨板とを隣接配置すると共に、樹脂成形品 の方向を可変させながら研磨する機構を設けることで、パートラインが様々な形状からなる樹脂成形品の何れも研磨処理することができる樹脂成形品のパートライン研磨装置を提供することにある。 The present invention has been developed to solve such problems. That is, the object of the present invention is to arrange a polishing belt and a plate-like polishing plate to be polished, and to provide a mechanism for polishing while changing the direction of the resin molded product. Another object of the present invention is to provide a part-line polishing apparatus for resin molded products that can polish any of the resin molded products.

本発明のパートライン研磨装置は、樹脂成形品Ｗのパートライン５２を研磨する、略垂直方向に回転するように無端ベルト状の研磨ベルト１と、この研磨ベルト１に隣接し、樹脂成形品Ｗのパートライン５２を仕上研磨する研磨板２とを配置したものである。樹脂成形品Ｗは、ワーク保持具３を用いてそのパートライン５２が略水平方向になるように担持するようになっている。このワーク保持具３は、ワーク保持具可動機構４により樹脂成形品Ｗと共に略水平の所定方向に移動させながら、凹凸部、角部や曲面部を有する樹脂成形品Ｗに形成されたパートライン５２を研磨するようになっている。
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view showing a part-line polishing apparatus for a resin molded product according to the present invention. FIG. 2 is a plan view showing a part-line polishing apparatus for a resin molded product according to the present invention. FIG. 3 is a side view showing a part-line polishing apparatus for a resin molded product according to the present invention.
The part-line polishing apparatus of the present invention polishes the part line 52 of the resin molded product W, and is adjacent to the polishing belt 1 so as to rotate in a substantially vertical direction, and the resin molded product W. The polishing plate 2 for finish polishing the part line 52 is disposed. The resin molded product W is supported using the work holder 3 so that the part line 52 is in a substantially horizontal direction. The workpiece holder 3 is a part line 52 formed on the resin molded product W having uneven portions, corner portions, and curved surfaces while being moved in a substantially horizontal predetermined direction together with the resin molded product W by the workpiece holder moving mechanism 4. Is supposed to be polished.
図１から図３の図示例では、研磨ベルト１と研磨板２とワーク保持具３とを配置したものを示している。実際のパートライン研磨装置は、樹脂成形品Ｗのパートライン５２を研磨した研磨滓が飛散しないように、これらの装置を筐体内に収容する。筐体の一面には、樹脂成形品Ｗを出し入れする部分だけに窓を設ける。この筐体の一面は内部が見られるように透明板で製造する。 In the illustrated examples of FIGS. 1 to 3, a polishing belt 1, a polishing plate 2, and a work holder 3 are arranged. The actual part line polishing apparatus accommodates these apparatuses in a housing so that the polishing rods polished on the part line 52 of the resin molded product W are not scattered. On one surface of the housing, a window is provided only in a portion where the resin molded product W is taken in and out. One side of this housing is made of a transparent plate so that the inside can be seen.
研磨ベルト１による研磨は、樹脂成形品Ｗのパートライン５２がめっき後に膨れ、クラックの起点となるため、この段差を除去することを目的とするものである。図１と図３の図示例では、樹脂成形品Ｗを研磨する位置において、上から下に向けて回転させている（矢示線参照）。これは、ワーク保持具３に取り付けた樹脂成形品Ｗが研磨中に外れないようにするためである。ワーク保持具３に対して樹脂成形品Ｗを取り付ける状態に応じて研磨ベルト１の回転方向が決定される。 Polishing with the polishing belt 1 is intended to remove this step because the part line 52 of the resin molded product W swells after plating and becomes a starting point of cracks. In the illustrated examples of FIGS. 1 and 3, the resin molded product W is rotated from the top to the bottom at the position where the resin molded product W is polished (see the arrow line). This is to prevent the resin molded product W attached to the workpiece holder 3 from being detached during polishing. The rotation direction of the polishing belt 1 is determined according to the state in which the resin molded product W is attached to the work holder 3.
この研磨ベルト１は、図３に示すように、略四角形状に配置したプーリ５と駆動輪６に掛け渡した。この駆動輪６は、モータ等の駆動機７に連結してプーリ５を回転させるものである。この駆動輪６又はプーリ５のいずれか1個は、研磨装置の使用に際して、研磨ベルト１にテンションをかけるようになっている。本発明の研磨装置を使用していないときは、駆動輪６又はプーリ５を研磨ベルト１に接触させないで、研磨ベルト１が伸びないようにしている。 As shown in FIG. 3, the polishing belt 1 was wound around a pulley 5 and a drive wheel 6 arranged in a substantially square shape. The driving wheel 6 is connected to a driving machine 7 such as a motor to rotate the pulley 5. Either one of the drive wheel 6 or the pulley 5 applies tension to the polishing belt 1 when the polishing apparatus is used. When the polishing apparatus of the present invention is not used, the driving belt 6 or the pulley 5 is not brought into contact with the polishing belt 1 so that the polishing belt 1 does not extend.
この研磨ベルト１は、例えば布製研磨ベルトで、ヤスリ目は＃１２０〜２０００が適当であった。この研磨ベルト１は、ベルトの伸びが使用中に比較的に小さいものが好ましい。研磨ベルト１の伸びが大きいと、一日の研磨後の製品のばらつきが大きくなるからである。この研磨ベルト１の長さと幅は、樹脂成形品Ｗの寸法やパートライン研磨装置の規模に応じて決定される。 The polishing belt 1 is, for example, a cloth polishing belt, and # 120 to 2000 is suitable for the file. The polishing belt 1 is preferably one in which the elongation of the belt is relatively small during use. This is because when the elongation of the polishing belt 1 is large, the variation of products after one day of polishing becomes large. The length and width of the polishing belt 1 are determined according to the dimensions of the resin molded product W and the scale of the part line polishing apparatus.
研磨ベルト１が樹脂成形品Ｗのパートライン５２を研磨する面と反対の面を、研磨ベルト１の内側から押圧するパッド８を設ける。このパッド８は樹脂成形品Ｗの凹部のパートライン５２を的確に研磨するものである。このパッド８により、樹脂成形品Ｗのパートライン５２の平坦面と曲面を均一に研磨できる。このパッド８の前後動の駆動は、樹脂成形品Ｗのパートライン５２の形状に応じて制御するようになっている。例えば、直線形状が多いパートライン５２には、押圧面が直線形状のパッド８を用い、凹凸が多いパートライン５２には、押圧面が小さいパッド８を用いることで、パートライン５２の様々な形状に対応できるようにする。また、パッド８の前後動の駆動制御はプログラムに連動させることができる。 A pad 8 is provided to press the surface opposite to the surface where the polishing belt 1 polishes the part line 52 of the resin molded product W from the inside of the polishing belt 1. The pad 8 accurately polishes the part line 52 of the concave portion of the resin molded product W. With this pad 8, the flat surface and the curved surface of the part line 52 of the resin molded product W can be uniformly polished. The back-and-forth movement of the pad 8 is controlled according to the shape of the part line 52 of the resin molded product W. For example, a pad 8 having a straight pressing surface is used for the part line 52 having a large linear shape, and a pad 8 having a small pressing surface is used for the part line 52 having a large unevenness. To be able to handle Further, the drive control of the back-and-forth movement of the pad 8 can be linked to the program.
研磨ベルト１に隣接して研磨板２を配置した。この研磨板２による仕上研磨は、研磨ベルト１の研磨により発生した樹脂成形品Ｗ周囲のエッジが膨れ、クラックの原因となるため丸みを付けるために仕上研磨することを目的とする。研磨板２は、略水平に配置した回転軸９に連結した回転板１０に取り付けたものである。本発明では研磨ベルト１の研磨する面と、研磨板２の研磨面とにより形成される角度αが９０度から１８０度の範囲内になるように、研磨ベルト１と研磨板２とを配置した。これは、研磨ベルト１による研磨に引き続いて研磨板２による仕上研磨するために樹脂成形品Ｗを迅速に移動させやすくするためである。 A polishing plate 2 was disposed adjacent to the polishing belt 1. The purpose of the finish polishing by the polishing plate 2 is to perform finish polishing in order to round off the edges around the resin molded product W generated by polishing the polishing belt 1 and causing cracks. The polishing plate 2 is attached to a rotating plate 10 connected to a rotating shaft 9 arranged substantially horizontally. In the present invention, the polishing belt 1 and the polishing plate 2 are arranged so that the angle α formed by the polishing surface of the polishing belt 1 and the polishing surface of the polishing plate 2 is in the range of 90 degrees to 180 degrees. . This is for facilitating the rapid movement of the resin molded product W in order to perform the final polishing with the polishing plate 2 following the polishing with the polishing belt 1.
研磨ベルト１を回転させる装置の一部に、研磨ベルト１に付着した研磨滓を除去するクリーニング機構１１を設ける。このクリーニング機構１１では、研磨ベルト１を超音波洗浄する方法を用いた。樹脂成形品Ｗの種類に応じては、水中で洗浄する方法、圧縮空気を吹き付ける方法、振動モータで落下させる方法等を用いることができる。このクリーニング機構１１では冷却効果も期待できる。このクリーニング機構１１により、研磨ベルト１の作動中に、研磨滓を除去しながら、樹脂成形品Ｗを研磨することができる。そこで、研磨ベルト１の研磨面の目詰まりによる研磨能力を低下させることなく連続的に研磨することが可能になる。 A cleaning mechanism 11 that removes polishing soot adhering to the polishing belt 1 is provided in a part of the apparatus that rotates the polishing belt 1. In this cleaning mechanism 11, a method of ultrasonically cleaning the polishing belt 1 was used. Depending on the type of the resin molded product W, a method of washing in water, a method of blowing compressed air, a method of dropping with a vibration motor, or the like can be used. The cleaning mechanism 11 can also be expected to have a cooling effect. With the cleaning mechanism 11, the resin molded product W can be polished while the polishing belt 1 is being operated while removing the polishing wrinkles. Therefore, it is possible to perform continuous polishing without reducing the polishing ability due to clogging of the polishing surface of the polishing belt 1.
研磨板２は、上述した研磨ベルト１より細かいヤスリ目であって、硬さが柔らかいものが好ましい。この研磨板２は硬すぎると研磨目が粗くなり、めっき後はそこが傷のようになることがあるからである。 The polishing plate 2 is preferably a file that is finer than the above-described polishing belt 1 and has a soft hardness. This is because if the polishing plate 2 is too hard, the polishing grain becomes rough and the plating plate may become scratched after plating.
図示例の研磨板２は、樹脂成形品Ｗを研磨する位置において、上から下に向けて回転させている。これは、ワーク保持具３に取り付けた樹脂成形品Ｗが研磨中に外れないようにするためである。ワーク保持具３に対して樹脂成形品Ｗを取り付けた状態に応じて研磨板２の回転方向が決定される。 The polishing plate 2 in the illustrated example is rotated from top to bottom at a position where the resin molded product W is polished. This is to prevent the resin molded product W attached to the workpiece holder 3 from being detached during polishing. The rotation direction of the polishing plate 2 is determined according to the state in which the resin molded product W is attached to the workpiece holder 3.
なお、回転軸９に、研磨板２を取り付ける回転板１０を偏心して連結することも可能である。このように研磨板２を偏心させて回転させ、樹脂成形品Ｗの周囲のパートライン５２を仕上研磨することにより、樹脂成形品Ｗの研磨面に回転方向の傷を付けないようにすることができる。 In addition, it is also possible to eccentrically connect the rotating plate 10 to which the polishing plate 2 is attached to the rotating shaft 9. In this way, the polishing plate 2 is eccentrically rotated and the part line 52 around the resin molded product W is finished and polished so that the polishing surface of the resin molded product W is not scratched in the rotational direction. it can.
研磨板２は、振動装置（図示していない）で振動研磨するように構成することも可能である。更に、この振動装置で研磨材３を振動の振幅を可変させながら、樹脂成形品Ｗの研磨面に傷を付けないように樹脂成形品Ｗの周囲のパートライン５２を仕上研磨することができる。 The polishing plate 2 can also be configured to vibrate and polish with a vibration device (not shown). Furthermore, the part line 52 around the resin molded product W can be finished and polished so as not to damage the polishing surface of the resin molded product W while varying the amplitude of vibration of the abrasive 3 with this vibration device.
ワーク保持具３は、スタンドの上に棒状の部材１２を立て、この上部に樹脂成形品Ｗの研磨する必要のない部分に開けた孔部分で回動しないように止め、更に枝部１３で上下方向への揺れが生じないように支える。例えば、合成樹脂製の取っ手では、ドア機構としての軸止め用の孔やスリットが開けられた部分を、棒状の部材１２に嵌めこみ、枝部１３で支えて研磨処理中に不要な揺れが生じないようにする。 The work holder 3 has a rod-like member 12 placed on a stand, and is stopped from rotating at a hole portion formed in a portion of the resin molded product W that does not need to be polished. Support so as not to shake in the direction. For example, in a handle made of a synthetic resin, a portion with a hole or slit for a shaft stop serving as a door mechanism is fitted into a rod-shaped member 12 and supported by a branch portion 13 to cause unnecessary shaking during the polishing process. Do not.
ワーク保持具可動機構４は、ワーク保持具３を樹脂成形品Ｗと共に、略水平の所定方向に移動させる機構である。例えば、３軸直交ロボットを用いて、研磨装置内において樹脂成形品Ｗを載せたワーク保持具３を移動させるものである。このワーク保持具可動機構４の動作は、樹脂成形品Ｗのパートライン５２の形状に応じて制御するようになっている。例えば、プログラムに連動してワーク保持具３を所定の方向に移動させることができる。 The workpiece holder moving mechanism 4 is a mechanism that moves the workpiece holder 3 together with the resin molded product W in a substantially horizontal predetermined direction. For example, the work holder 3 on which the resin molded product W is placed is moved in the polishing apparatus using a three-axis orthogonal robot. The operation of the workpiece holder moving mechanism 4 is controlled according to the shape of the part line 52 of the resin molded product W. For example, the workpiece holder 3 can be moved in a predetermined direction in conjunction with the program.
このワーク保持具可動機構４は、必ずしも略水平方向のみ移動させる必要はない。更に上下方向の移動を組み合わせることができる。例えば、パートライン５２が直線的に形成されていない樹脂成形品Ｗであっても、その形状に合わせて樹脂成形品Ｗを水平方向と上下方向の移動を組み合わせながら研磨することができる。同様に、パートライン５２が直線的に形成されている樹脂成形品Ｗであっても、樹脂成形品Ｗの軸方向に対して傾斜状態でワーク保持具３を取り付けたときにも、そのパートライン５２の形状に合わせて樹脂成形品Ｗを水平方向と上下方向の移動を組み合わせながら研磨することができる。
あるいは、ワーク保持具３自体は、昇降し得るように構成することも可能である。
The workpiece holder moving mechanism 4 is not necessarily moved only in the substantially horizontal direction. Furthermore, movement in the vertical direction can be combined. For example, even if the part line 52 is a resin molded product W that is not formed linearly, the resin molded product W can be polished while combining the movement in the horizontal direction and the vertical direction according to the shape. Similarly, even when the part line 52 is a resin molded product W formed linearly, when the workpiece holder 3 is attached in an inclined state with respect to the axial direction of the resin molded product W, the part line 52 According to the shape of 52, the resin molded product W can be polished while combining the movement in the horizontal direction and the vertical direction.
Alternatively, the workpiece holder 3 itself can be configured to be able to move up and down.

While moving the product W in a substantially horizontal direction, the part line around the resin molded product W is continuously polished. Thus, smooth polishing of the part line 52 can be performed.
次に、樹脂成形品Ｗの凹形状部のパートライン５２を、図４の（ｆ）から（ｊ）に示すように、研磨板２に押し当てながら仕上研磨し、樹脂成形品Ｗの周囲のパートライン５２が研磨板２を擦るように、樹脂成形品Ｗを略水平方向に移動させながら、樹脂成形品Ｗの周囲のパートライン５２を連続して仕上研磨する。これにより円滑にパートライン５２の仕上研磨を実施することができる。 Next, as shown in (f) to (j) of FIG. 4, the part line 52 of the concave portion of the resin molded product W is finished and polished while being pressed against the polishing plate 2. The part line 52 around the resin molded product W is finish-polished continuously while moving the resin molded product W in a substantially horizontal direction so that the part line 52 rubs the polishing plate 2. Thereby, the finish polishing of the part line 52 can be carried out smoothly.
このように凹凸部、角部や曲面部を有する樹脂成形品Ｗに形成されたパートライン５２について、研磨ベルト１による連続した研磨と、研磨板２による連続した仕上研磨が終了したら、ワーク保持具３から取り外し研磨処理が完了する。上述と同様な工程で次の樹脂成形品Ｗをセットする。 When the continuous polishing by the polishing belt 1 and the continuous finish polishing by the polishing plate 2 are finished for the part line 52 formed on the resin molded product W having the uneven portion, the corner portion, and the curved surface portion in this way, the workpiece holder 3 is removed and the polishing process is completed. The next resin molded product W is set in the same process as described above.
なお、本発明は上述した発明の実施の形態に限定されず、研磨ベルト１による研磨と、研磨板２を隣接配置し、ワーク保持具可動機構４を可動させて樹脂成形品Ｗのパートライン５２を迅速に連続して研磨することができる構成であれば、図示したような構造に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。 The present invention is not limited to the embodiment of the invention described above, and the polishing by the polishing belt 1 and the polishing plate 2 are arranged adjacent to each other, and the workpiece holder moving mechanism 4 is moved to move the part line 52 of the resin molded product W. Of course, the structure is not limited to the structure shown in the figure as long as it can rapidly and continuously be polished, and various changes can be made without departing from the scope of the present invention.
本発明の樹脂成形品のパートライン研磨装置は、凹凸部、角部や曲面部を有する樹脂成形品について利用できるだけでなく、板状の単純な形状の樹脂成形品のパートラインの研磨に利用することができる。 The resin molded product part-line polishing apparatus according to the present invention can be used not only for resin molded products having uneven portions, corners and curved portions, but also for polishing a plate-shaped simple-shaped resin molded product part line. be able to.
