Description

【0001】
【発明が属する技術分野】
本発明は、樹脂成形機から成形品を取出す際に成形品を保持するチャック姿勢を反転回動する成形品取出機のチャック姿勢制御装置に関する。
【0002】
【従来技術】
成形品取出機により金型内からの成形品を樹脂成形機の外部に取出す際には、チャックの成形品保持面を金型のパーティング面に相対する垂直状態に、また金型外の解放位置に成形品を解放する際には、チャックの成形品保持面が下方を向く水平状態になるようにそれぞれ反転回動するようにチャック姿勢を制御している。
【0003】
このチャック姿勢を制御するチャック姿勢制御装置としては、支持体にシリンダーチューブが固定された油圧作動や空圧作動のシリンダーのロッドにトグル機構やリンク機構を介してチャック取付け部材を連結し、シリンダーの作動に伴ってチャック取付け部材を約90度の角度で往復回動するように構成している。
【0004】
【発明が解決しようとする課題】
上記したチャック姿勢制御装置にあっては、垂直位置と水平位置の間でチャックを短時間で、かつ高い位置精度で回動させると共に回動停止時にはチャックによる成形品の保持不良や位置ずれを防止する必要から衝撃を少なくすることが要求される。
【0005】
しかし、上記したシリンダー構造のチャック姿勢制御装置にあっては、チャックをそれぞれの位置で回動停止させる際には、チャック取付け部材を支持体に設けられたゴムブロック等のストッパに衝突させて衝撃を吸収しているが、チャック取付け部材の衝撃を有効に吸収するには、ストッパを大型化する必要がある。
【0006】
しかし、チャック取付け部材の取付け箇所にはトグル機構やリンク機構が設けられて余剰空間が少ないため、大型のストッパを取付けることが事実上困難で、衝撃を有効に吸収できなかった。
【0007】
また、ストッパにより回動停止時の衝撃を緩衝する構造にあっては、それぞれの回動位置にストッパを取付ける必要があるが、狭い空間内に複数のストッパを取付けるためのスペースを確保すること自体が困難で、衝撃を充分に吸収することができなかった。
【0008】
これらの欠点は、シリンダーを低速度で作動させることにより解決できるが、この場合にあってはチャックの反転回動時間が長くなって成形品の取出し時間(サイクル)が長くなる問題を有している。
【0009】
更に、チャック取付け部材の回動停止時の衝撃を吸収する部材としては、内蔵された軸の当接に従って内蔵された空気や油を徐々に放出して衝撃を和らげるアブソーバを一般に使用しているが、狭い空間にこの種のアブソーバを取付ける場合にあっては、回動支点とアブソーバの距離が短くなることによりアブソーバの偏角度が大きくなって軸に過大な負荷が作用することになる。これによりアブソーバ自体の耐久性が悪くなり、長期にわたって安定的に衝撃を吸収できない問題を有している。
【0010】
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、その課題とする処は、チャックを高速度で姿勢制御しながら回動停止時における衝撃を緩和して成形品の位置ずれや保持不良を防止することができる成形品取出機のチャック姿勢制御装置を提供することにある。
【0011】
本発明の他の課題は、異なる位置でチャックを回動停止させる場合であっても1個の衝撃吸収部材を使用して回動停止時における衝撃を効率的に吸収して装置自体の簡易化及び低コスト化を図ることができる成形品取出機のチャック姿勢制御装置を提供することにある。
【0012】
本発明の他の課題は、チャックの回動停止時における衝撃を長期にわたって安定的に吸収して停止位置精度を確保することができる成形品取出機のチャック姿勢制御装置を提供することにある。
【0013】
本発明は、成形品を保持するチャックを移動制御して樹脂成形機から成形品を取出す成形品取出機に装着され、チャックの成形品保持面を所望の第1位置と第2位置の間で回動させるチャック姿勢制御装置は、チャックを移動させる可動部材に取付けられる支持体に対し、チャック取付け面に取付けられたチャックの上記成形品保持面が第1及び第2位置の間で往復回動するように支持されるチャック取付け部材と、支持体に基端部が揺動可能に支持されると共にチャック取付け部材の回動中心から偏位した箇所にロッドが連結され、上記成形品保持面が第1及び第2位置にそれぞれに回動した際に、常に一定位置で揺動停止するシリンダー部材と、シリンダー部材に設けられ、上記成形品保持面が第1及び第2位置にそれぞれ回動停止する際に、支持体との協働により衝撃を吸収する衝撃吸収部材とを備えたことを特徴とする。
【0014】
【発明の実施形態】
以下に実施形態を示す図に従って本発明を説明する。
図1〜図2において、成形品取出機1はチャック3を樹脂成形機(図示せず)の長手方向(前後方向)、長手直交方向(左右方向)及び上下方向の三次元方向へ移動制御して金型内の成形品を樹脂成形機外へ取出すもので、左右方向へ延出する本体フレーム5はその基台部が樹脂成形機の固定側プラテン7の上面に固定されている。
【0015】
本体フレーム5上には左右走行体9が左右方向へ移動するように支持され、前後方向へ延出して左右走行体9に設けられた前後フレーム11には前後走行体13が前後方向へ移動するように支持されている。
【0016】
該前後走行体13には昇降アーム15が上下方向へ移動するように支持され、昇降アーム15の下部にはチャック3が、チャック姿勢制御装置17を介して取付けられる。該チャック姿勢制御装置17は支持体としての支持ベース19の上部にシリンダーチューブ21aの基端部が揺動可能に軸支されたシリンダー21と、支持ベース19の下部に設けられた軸支部23に回動するように軸支され、一端部にシリンダー21のロッド21bが連結されるアーム25aを有した取付けブラケット25とから構成される。
【0017】
取付けブラケット25はシリンダー21のロッド21bが伸長作動した際に、取付けブラケット25のチャック取付け面25b、従ってチャック3の成形品保持面が垂直になる第1位置と、シリンダー21のロッド21bが縮小作動した際に、チャック取付け面25b、従ってチャック3の成形品保持面が下方を向いて水平になる第2位置との間で回動される。
【0018】
また、取付けブラケット25に対するロッド21bの連結は、取付けブラケット25が第1位置及び第2位置にそれぞれ位置した際にシリンダー21が共通の揺動原点位置に戻り、かつ第1位置及び第2位置の回動途中、具体的には取付けブラケット25が45度回動した際にシリンダー21の揺動角度が最大になるように軸支位置から偏位した箇所で連結する。
【0019】
シリンダーチューブ21aの先端側には取付けブラケット25の回動停止時における衝撃を吸収する空圧式または油圧式のアブソーバやゴム等の弾性ブロック等からなる1個の衝撃吸収部材27が取付けられる。図はアブソーバ形式の衝撃吸収部材27を示し、取付けブラケット25が第1位置及び第2位置において回動停止する際に、支持ベース19に当接するプランジャー27aによりエアー又は油を徐々に放出させることにより回動停止に伴う衝撃を吸収するものである。
【0020】
尚、チャック3は取付けブラケット25のチャック取付け面25bに着脱可能に固定されるチャック板3aに対し、成形品を吸着する吸着部材や把持するエアーシリンダ等の複数個の保持部材3bを取付けた構造からなる。
【0021】
次に、チャック姿勢制御装置17の作用を説明するのに先立って成形品取出機1の成形品取出し作用を説明すると、チャック3が樹脂成形機の金型上方に位置した状態で樹脂成形機から型開完了信号が入力されると、昇降アーム15を下降制御してチャック3を型開した金型間に進入させた後、前後走行体13を前進移動制御してチャック3を可動金型内に保持させた成形品を近接させる。
【0022】
上記状態にて可動金型内の突き出し機構を駆動して成形品をチャック3に向って突き出して保持させるタイミングで前後走行体13を後退移動制御してチャック3に保持された成形品を可動金型内から完全に抜き出した後、昇降アーム15を上昇制御してチャック3を金型間から抜け出させる。尚、チャック3が金型間から抜け出すタイミングで樹脂成形機へ成形開始指令信号を出力して次の成形作業を開始させる。
【0023】
次に、チャック3が上方へ移動した状態で左右走行体9を本体フレーム5の端部に設定された解放位置側へ移動制御した後、必要に応じて前後走行体13を前後進移動及び昇降アーム15を昇降移動させてチャック3を所定の解放位置に位置させた後にチャック3による成形品の保持を解除して取出し動作を完了する。
【0024】
成形品を保持したチャック3を上昇位置へ移動する際或いは成形品を保持したチャック3を解放位置へ移動した際に、チャック姿勢制御装置17を作動してチャック3による成形品の保持姿勢を制御させる。
【0025】
即ち、成形品を保持したチャック3が左右方向へ移動する際に成形品の高さを低くしてタイバーに干渉するのを回避するため、成形品を保持したチャック3が金型から抜け出す上昇位置へ移動する途中に反転回動して水平状態にしたり、また、解放位置においてチャック3による成形品の保持を解除する際に、例えば成形品が取出される搬出コンベヤーや搬出シューターの載置面に成形品を相対させるために反転回動して水平状態にさせることがある。
【0026】
上記した何れの場合であっても、シリンダー21をそのロッド21bが縮小する方向へ作動し、軸支部23を中心に取付けブラケット25を回動してチャック取付け面25bを水平状態にさせる。このとき、図3及び図4に示すようにシリンダー21は取付けブラケット25の回動に伴って所定の角度で揺動した後に原位置に戻ることになるが、該取付けブラケット25が水平状態で回動停止する際に、支持ベース19に対して衝撃吸収部材27を徐々に当接させることにより取付けブラケット25が回動停止する際の衝撃を吸収させる。
【0027】
反対に、チャック取付け面25bが水平状態を向いた状態から垂直状態を向く状態に戻すには、シリンダー21を、そのロッド21bが伸張する方向へ作動して軸支部23を中心に取付けブラケット25を回動してチャック取付け面25bを垂直状態にさせる。このとき、シリンダー21は取付けブラケット25の回動に伴って所定の角度で揺動した後に原位置に戻ることになるが、該取付けブラケット25が垂直状態で回動停止する際に、図5に示すように支持ベース19に対して衝撃吸収部材27を徐々に当接させることにより取付けブラケット25が回動停止する際の衝撃を吸収させる。
【0028】
本実施形態は、取付けブラケット25を90度の角度をおいた垂直位置と水平位置との間で回動させる際に所定の角度で往復揺動するシリンダー21に装着された衝撃吸収部材27により取付けブラケット25が回動停止する際の衝撃を吸収することにより取付けブラケット25を高速度で回動させる場合であっても、チャック3に保持された成形品が位置ずれしたり、保持不良になったりするのを回避することができる。
【0029】
また、取付けブラケット25が上記した垂直位置と水平位置の間で回動停止する際にシリンダー21自体、常に一定の位置に揺動停止するように連結されるため、各回動位置に共通して1個の衝撃吸収部材27により衝撃を吸収することにより部品点数を少なくして装置自体を低コスト化することができる。
【0030】
更に、シリンダー21の揺動支点から距離をおいた位置に衝撃吸収部材27を取り付け、支持ベース19に対するプランジャー27aの偏角度を小さくして過大な負荷が作用するのを防止することができ、回動停止時の衝撃を長期にわたって安定的に吸収することができる。
【0031】
上記説明は、チャックを三次元方向へ移動制御して成形品を取出す形式の成形品取出機としたが、本発明に係るチャック姿勢制御装置が装着される成形品取出機としては、チャックを旋回移動させて成形品を取出す旋回形式、チャックを樹脂成形機の側方から進入させて成形品を取出す横走行形式のいずれであってもよい。
【0032】
【発明の効果】
本発明は、チャックを高速度で姿勢制御しながら回動停止時における衝撃を緩和して成形品の位置ずれや保持不良を防止することができる。また、異なる位置でチャックを回動停止させる場合であっても1個の衝撃吸収部材を使用して回動停止時における衝撃を効率的に吸収して装置自体の簡易化及び低コスト化を図ることができる。更に、チャックの回動停止時における衝撃を長期にわたって安定的に吸収して停止位置精度を確保することができる。

[Technical field to which the invention belongs]
The present invention relates to a chuck posture control device for a molded product take-out machine that reverses and rotates a chuck posture for holding a molded product when taking out the molded product from a resin molding machine.
[0002]
[Prior art]
When taking out the molded product from the mold by the molded product take-out machine to the outside of the resin molding machine, make the molded product holding surface of the chuck perpendicular to the parting surface of the mold and release it outside the mold. When the molded product is released to the position, the chuck posture is controlled so that the molded product holding surface of the chuck is rotated in the reverse direction so as to be in a horizontal state facing downward.
[0003]
As a chuck posture control device for controlling the chuck posture, a chuck mounting member is connected to a rod of a hydraulically or pneumatically operated cylinder in which a cylinder tube is fixed to a support body via a toggle mechanism or a link mechanism. The chuck mounting member is configured to reciprocate at an angle of about 90 degrees with the operation.
[0004]
[Problems to be solved by the invention]
In the chuck attitude control device described above, the chuck is rotated between the vertical position and the horizontal position in a short time with high positional accuracy, and when the rotation is stopped, the holding of the molded product by the chuck and misalignment are prevented. It is required to reduce the impact because it is necessary.
[0005]
However, in the chuck posture control device having the above-described cylinder structure, when the chuck is stopped at each position, the chuck mounting member is caused to collide with a stopper such as a rubber block provided on the support to perform an impact. However, it is necessary to enlarge the stopper in order to effectively absorb the impact of the chuck mounting member.
[0006]
However, since a toggle mechanism and a link mechanism are provided at the attachment location of the chuck attachment member and there is little excess space, it is practically difficult to attach a large stopper, and the impact cannot be absorbed effectively.
[0007]
In addition, in the structure where the impact when stopping rotation is buffered by the stopper, it is necessary to attach the stopper to each rotation position, but securing the space for mounting a plurality of stoppers in a narrow space itself It was difficult to absorb the impact sufficiently.
[0008]
These disadvantages can be solved by operating the cylinder at a low speed. In this case, however, there is a problem that the time for reversing rotation of the chuck becomes long and the take-out time (cycle) of the molded product becomes long. Yes.
[0009]
Further, as a member that absorbs an impact when the chuck mounting member stops rotating, an absorber that gradually releases the built-in air or oil according to the contact of the built-in shaft is generally used. When this type of absorber is mounted in a narrow space, the distance between the rotation fulcrum and the absorber is shortened, so that the eccentric angle of the absorber is increased and an excessive load is applied to the shaft. As a result, the durability of the absorber itself deteriorates, and there is a problem that the shock cannot be stably absorbed over a long period of time.
[0010]
The present invention has been invented in order to solve the above-described conventional drawbacks. The problem is that the position of the molded product is reduced by reducing the impact when the rotation is stopped while controlling the posture of the chuck at a high speed. An object of the present invention is to provide a chuck posture control device for a molded product take-out machine that can prevent displacement and holding failure.
[0011]
Another object of the present invention is to simplify the apparatus itself by efficiently absorbing the impact when the rotation is stopped by using one impact absorbing member even when the chuck is stopped at different positions. Another object of the present invention is to provide a chuck posture control device for a molded product take-out machine that can reduce costs.
[0012]
Another object of the present invention is to provide a chuck attitude control device for a molded product take-out machine that can stably absorb a shock at the time of stopping the rotation of the chuck over a long period of time and ensure the stop position accuracy.
[0013]
The present invention is mounted on a molded product take-out machine that takes out a molded product from a resin molding machine by controlling the movement of a chuck that holds the molded product, and the molded product holding surface of the chuck is placed between a desired first position and a second position. chuck posture control device for pivoting, against the support to be attached to a movable member for moving the chuck, the molded article holding surface of the chuck mounted on the chuck mounting surface reciprocally rotated between the first and second position A chuck mounting member that is supported in such a manner that the base end portion is swingably supported by the support body, and a rod is connected to a position that is deviated from the center of rotation of the chuck mounting member. A cylinder member that always oscillates and stops at a fixed position when rotated to the first and second positions respectively, and provided on the cylinder member, and the molded product holding surface stops rotating at the first and second positions, respectively. Do In, characterized in that a shock absorbing member for absorbing the shock in cooperation with the support.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the drawings showing embodiments.
1 to 2, the molded product take-out machine 1 controls the movement of the chuck 3 in the three-dimensional direction of the resin molding machine (not shown) in the longitudinal direction (front-rear direction), the longitudinal orthogonal direction (left-right direction), and the vertical direction. The molded product in the mold is taken out of the resin molding machine, and the main body frame 5 extending in the left-right direction has a base portion fixed to the upper surface of the stationary platen 7 of the resin molding machine.
[0015]
The left and right traveling bodies 9 are supported on the main body frame 5 so as to move in the left and right directions, and the front and rear traveling bodies 13 move in the front and rear directions on the front and rear frames 11 that extend in the front and rear directions and are provided on the left and right traveling bodies 9. So that it is supported.
[0016]
A lift arm 15 is supported on the front and rear traveling body 13 so as to move in the vertical direction, and a chuck 3 is attached to a lower portion of the lift arm 15 via a chuck posture control device 17. The chuck attitude control device 17 includes a cylinder 21 in which a base end portion of a cylinder tube 21 a is pivotally supported on an upper portion of a support base 19 as a support, and a shaft support portion 23 provided on a lower portion of the support base 19. The mounting bracket 25 includes an arm 25a that is pivotally supported so as to rotate and is connected to the rod 21b of the cylinder 21 at one end.
[0017]
In the mounting bracket 25, when the rod 21b of the cylinder 21 is extended, the chuck mounting surface 25b of the mounting bracket 25 , and hence the molded product holding surface of the chuck 3 is vertical, and the rod 21b of the cylinder 21 is contracted. At this time, the chuck mounting surface 25b , and hence the molded product holding surface of the chuck 3, is rotated between the second position where the chuck mounting surface 25b is directed downward and becomes horizontal.
[0018]
Further, the rod 21b is connected to the mounting bracket 25 when the mounting bracket 25 is positioned at the first position and the second position, respectively, when the cylinder 21 returns to the common swinging origin position, and the first position and the second position. In the middle of the rotation, specifically, when the mounting bracket 25 is rotated 45 degrees, the cylinder 21 is connected at a position deviated from the shaft support position so that the swing angle of the cylinder 21 is maximized.
[0019]
One shock absorbing member 27 made of a pneumatic or hydraulic absorber, an elastic block such as rubber, or the like that absorbs an impact when the mounting bracket 25 stops rotating is attached to the distal end side of the cylinder tube 21a. The figure shows an absorber-type shock absorbing member 27. When the mounting bracket 25 stops rotating at the first position and the second position, air or oil is gradually released by a plunger 27a that contacts the support base 19. This absorbs the impact associated with the rotation stop.
[0020]
The chuck 3 has a structure in which a plurality of holding members 3b such as an adsorbing member that adsorbs a molded product and an air cylinder that holds a molded product are attached to a chuck plate 3a that is detachably fixed to the chuck mounting surface 25b of the mounting bracket 25. Consists of.
[0021]
Next, prior to explaining the operation of the chuck posture control device 17, the operation of taking out the molded product of the molded product take-out machine 1 will be described. From the resin molding machine with the chuck 3 positioned above the mold of the resin molding machine. When a mold opening completion signal is input, the lifting arm 15 is controlled to move down and the chuck 3 is moved between the molds that have been opened, and then the front and rear traveling body 13 is controlled to move forward to control the chuck 3 within the movable mold. The molded product held in is brought close to each other.
[0022]
In this state, the ejector mechanism in the movable mold is driven to eject the molded product toward the chuck 3 and hold the molded product back and forth so that the molded product held on the chuck 3 can be moved. After complete extraction from the mold, the lifting arm 15 is controlled to be lifted so that the chuck 3 is pulled out from between the molds. A molding start command signal is output to the resin molding machine at the timing when the chuck 3 comes out from between the molds, and the next molding operation is started.
[0023]
Next, after the chuck 3 is moved upward, the left and right traveling bodies 9 are controlled to move to the release position set at the end of the main body frame 5, and then the front and rear traveling bodies 13 are moved forward and backward as needed. After the arm 15 is moved up and down to position the chuck 3 at a predetermined release position, the holding of the molded product by the chuck 3 is released and the take-out operation is completed.
[0024]
When the chuck 3 holding the molded product is moved to the raised position or the chuck 3 holding the molded product is moved to the release position, the chuck posture control device 17 is operated to control the holding posture of the molded product by the chuck 3. Let
[0025]
That is, when the chuck 3 holding the molded product moves in the left-right direction, the height of the molded product is lowered to avoid interference with the tie bar, so that the chuck 3 holding the molded product is lifted out from the mold. When the molded product is held in the horizontal state by being reversed and rotated in the middle of the movement, or when the holding of the molded product by the chuck 3 is released at the release position, for example, on the placing surface of the carry-out conveyor or carry-out shooter from which the molded product is taken out In order to make a molded product relatively, there is a case where it is reversed and rotated to be in a horizontal state.
[0026]
In any case described above, the cylinder 21 is operated in the direction in which the rod 21b is contracted, and the mounting bracket 25 is rotated about the shaft support portion 23 to bring the chuck mounting surface 25b into a horizontal state. At this time, as shown in FIGS. 3 and 4, the cylinder 21 swings at a predetermined angle as the mounting bracket 25 rotates, and then returns to the original position. However, the mounting bracket 25 rotates in a horizontal state. When the movement is stopped, the shock absorbing member 27 is gradually brought into contact with the support base 19 to absorb the shock when the mounting bracket 25 stops rotating.
[0027]
On the other hand, in order to return the chuck mounting surface 25b from the horizontal state to the vertical state, the cylinder 21 is operated in the direction in which the rod 21b extends to mount the mounting bracket 25 around the shaft support portion 23. It rotates to bring the chuck mounting surface 25b into a vertical state. At this time, the cylinder 21 swings at a predetermined angle along with the rotation of the mounting bracket 25 and then returns to the original position. When the mounting bracket 25 stops rotating in the vertical state, the cylinder 21 is shown in FIG. As shown, the impact absorbing member 27 is gradually brought into contact with the support base 19 to absorb the impact when the mounting bracket 25 stops rotating.
[0028]
In this embodiment, when the mounting bracket 25 is rotated between a vertical position and a horizontal position at an angle of 90 degrees, the mounting bracket 25 is mounted by an impact absorbing member 27 mounted on a cylinder 21 that reciprocally swings at a predetermined angle. Even when the mounting bracket 25 is rotated at a high speed by absorbing an impact when the bracket 25 stops rotating, the molded product held by the chuck 3 may be misaligned or may be poorly held. Can be avoided.
[0029]
In addition, when the mounting bracket 25 stops rotating between the vertical position and the horizontal position, the cylinder 21 itself is connected so as to always swing and stop at a fixed position. By absorbing the impact by the single impact absorbing member 27, the number of parts can be reduced and the cost of the apparatus itself can be reduced.
[0030]
Furthermore, an impact absorbing member 27 is attached at a position away from the swinging fulcrum of the cylinder 21, and the deflection angle of the plunger 27a with respect to the support base 19 can be reduced to prevent an excessive load from acting. The impact at the time of stopping rotation can be stably absorbed over a long period of time.
[0031]
In the above description, the molded product take-out machine is a type that takes out the molded product by controlling the movement of the chuck in the three-dimensional direction. However, as the molded product take-out machine to which the chuck attitude control device according to the present invention is attached, the chuck is swung. Either a swivel type in which the molded product is taken out by moving, or a lateral running type in which the chuck is entered from the side of the resin molding machine to take out the molded product may be used.
[0032]
【The invention's effect】
According to the present invention, it is possible to mitigate the impact at the time of stopping the rotation while controlling the posture of the chuck at a high speed to prevent the misalignment and the holding failure of the molded product. Even when the chuck is rotated and stopped at different positions, the impact of the rotation is effectively absorbed by using one impact absorbing member, thereby simplifying the apparatus itself and reducing the cost. be able to. Furthermore, it is possible to stably absorb the impact at the time of stopping the rotation of the chuck over a long period of time and ensure the stop position accuracy.
