Description

本発明は、成形品を射出成形機の機外に取り出す成形品取出装置と組み合わされた射出成形機に関し、エジェクト装置の突き出し動作に加えて型締装置の型開き動作を行うことによって、成形品を金型から成形品取出装置の成形品受け取り装置に受け渡す射出成形機に関する。   The present invention relates to an injection molding machine combined with a molded product take-out device for taking out a molded product out of an injection molding machine, and by performing a mold opening operation of a mold clamping device in addition to an ejecting operation of an eject device. The present invention relates to an injection molding machine that delivers a product from a mold to a molded product receiving device of a molded product take-out device.

金型で成形された成形品は、多くの場合、型締装置の近傍に装備された成形品取出装置によって金型から射出成形機の側方に取り出される。このため、従来の成形品取出装置は、成形品をクランプするチャック又は吸着する吸着パッド若しくは収容する収容ポケット等を有する受け取り装置と、その受け取り装置を金型と前記側方との間で往復させる長尺のアーム装置と、その受け取り装置をそのアーム装置と共に型開閉方向に移動する型開閉方向移動軸装置と、その受け取り装置をその型開閉方向に対して直角な方向に移動する取出方向移動軸装置と、それらのための駆動制御装置とを備えていた。そして、この成形品取出装置は、通常固定プラテン上に固定される。このように、従来の成形品取出装置は、少なくとも、型開閉方向移動軸装置と取出方向移動軸装置の2つの移動軸装置を含んでいた。   In many cases, the molded product molded by the mold is taken out from the mold to the side of the injection molding machine by a molded product take-out device installed in the vicinity of the mold clamping device. For this reason, the conventional molded product take-out device reciprocates the receiving device having a chuck for clamping the molded product, a suction pad for suction or a receiving pocket for storing the receiving device, and the side between the mold and the side. A long arm device, a mold opening / closing direction moving shaft device that moves the receiving device together with the arm device in a mold opening / closing direction, and a take-out direction moving shaft that moves the receiving device in a direction perpendicular to the mold opening / closing direction Devices and drive control devices for them. And this molded product taking-out apparatus is normally fixed on a stationary platen. As described above, the conventional molded product take-out device includes at least two moving shaft devices, ie, a mold opening / closing direction moving shaft device and a taking-out direction moving shaft device.

このような成形品取出装置の取り出し制御は、射出成形機側の型開きから型閉じまでの間に成形品を突き出す通常のエジェクト動作と関連付けられた制御であるが、別途に挿入される特殊な制御であった。それで、従来の射出成形機の制御装置には、型締装置の可動プラテンの型開閉位置や型締力を設定する従来の型開閉設定画面と、エジェクト装置の突き出し動作を設定する従来の突き出し設定画面は用意されていたが、取出装置の細かい設定制御画面は用意されておらず、その画面は取出装置側で用意されるものであった。もっとも、このことは、成形品の取り出し動作中に射出成形機側の可動プラテンを型開閉方向に移動制御する必要が全くなかったから当然のことである。   Such take-out control of the molded product take-out device is a control associated with a normal eject operation for ejecting the molded product between the mold opening and mold closing on the injection molding machine side, but is a special insert inserted separately. It was control. Therefore, the conventional injection molding machine control device has a conventional mold opening / closing setting screen for setting the mold opening / closing position and clamping force of the movable platen of the mold clamping device, and a conventional ejection setting for setting the ejection operation of the ejection device. Although the screen was prepared, the detailed setting control screen of the take-out device was not prepared, and the screen was prepared on the take-out device side. However, this is natural because there was no need to control the movement of the movable platen on the injection molding machine side in the mold opening / closing direction during the operation of taking out the molded product.

ところで、射出成形の分野では、より精密で微細な成形品を成形する分野が拡大の一途にある。この分野では、成形品の数量が莫大であることから、高い生産性が当然に要求され、取出装置においても成形のハイサイクル化に対応することが要求される。その上、取出装置そのものの低コスト化と長期にわたる耐久性も要求される。特に成形機が小型である場合には、成形機に対する取出機の価格が割高であってはならず、また、構成が可能な限り簡素化されてハイサイクル運転でも故障が最小限に抑えられなければならない。   By the way, in the field of injection molding, the field of molding more precise and fine molded products is expanding. In this field, since the number of molded products is enormous, high productivity is naturally required, and the take-out device is also required to cope with a high cycle of molding. In addition, the cost of the take-out device itself and long-term durability are also required. Especially when the molding machine is small, the price of the unloader with respect to the molding machine must not be expensive, and the configuration should be simplified as much as possible to minimize failures even in high cycle operation. I must.

そこで、このハイサイクル化と確実な取り出し性能のために、成形品よりも大きな収納ポケットを有して、それをエアー通路から吸引して負圧にすることにより、成形品をその収納ポケットに吸引して収納する取出機が提案されている(特許文献1参照)。また、同様の目的に加えて取出装置の低コスト化を図るために、成形品を受け取る成形品受けがエアーの噴射によるエアーの流れにより成形品を補足する構成の成形品の取り出し装置が提案されている(特許文献2参照)。特にこの特許文献2は、その駆動手段をカセット式金型の交換装置によって代替えする取り出し装置を開示している。
特開昭63−209913号公報 特許2802294号公報
Therefore, for this high cycle and reliable take-out performance, it has a storage pocket larger than the molded product, and sucks it from the air passage to make negative pressure, so that the molded product is sucked into the storage pocket. A take-out machine for storing is proposed (see Patent Document 1). In addition to the same purpose, in order to reduce the cost of the take-out device, a molded product take-out device is proposed in which the molded product receiver that receives the molded product supplements the molded product with the air flow caused by air injection. (See Patent Document 2). In particular, this Patent Document 2 discloses a take-out device in which the drive means is replaced by a cassette type mold exchanging device.
JP-A 63-209913 Japanese Patent No. 2802294

しかしながら、上記特許文献の取出機又は成形品の取り出し装置は、その装置の低コスト化と耐久性の向上という課題を充分に解決しているとは言い難い。   However, it is difficult to say that the take-out machine or the take-out apparatus for molded articles in the above-mentioned patent document sufficiently solves the problems of cost reduction and durability improvement of the apparatus.

前者の公報で開示された取出機又は成形品の取り出し装置は、型開閉方向移動軸装置を有するのでその分だけ装置を簡素化することができず、取り出し装置の低コスト化にも限界がある。その上、その取出機は剛性的に不充分で故障し難いとは言えない。なぜなら、その取出機は、長尺のアーム装置の先端に受け取り装置を備えて型開閉方向への移動をそのアーム装置の基部の型開閉方向移動軸装置によって行うので、受け取り装置の型開閉方向への移動の際に、その移動軸装置とそのアーム部分の基部の近傍とに大きな曲げモーメント的な負荷を受けるからである。   The take-out machine or molded product take-out device disclosed in the former publication has a mold opening / closing direction moving shaft device, so the device cannot be simplified correspondingly, and there is a limit to the cost reduction of the take-out device. . In addition, the unloader is not rigid enough to fail. This is because the take-out machine is provided with a receiving device at the tip of the long arm device and moves in the mold opening / closing direction by the mold opening / closing direction moving shaft device at the base of the arm device. This is because a large bending moment-like load is applied to the moving shaft device and the vicinity of the base portion of the arm portion during the movement.

また、後者で開示された取出機は、カセット式金型の交換装置を利用するので受け取り装置に駆動装置を不要としているが、その交換装置の型開閉方向の移動軸装置を利用する限り、取出機の型開閉方向移動軸装置に相当するその移動軸装置において上記の前者における問題点を依然として有している。その上、その移動軸装置の稼動回数が格段に増加するための新たな設計変更が必要となる。   Further, since the take-out machine disclosed in the latter uses a cassette type mold exchanging device, the receiving device does not require a drive device. The moving shaft device corresponding to the moving shaft device in the mold opening / closing direction of the machine still has the above-mentioned problems. In addition, a new design change is necessary for the number of operations of the moving shaft device to increase dramatically.

そこで、本発明の射出成形機は、上記の問題点を解決するため、金型(4)を型開閉方向に移動制御する型締装置(3)と、成形品(11)を前記金型から前記型開閉方向に突き出すエジェクト装置(35)とを含む射出成形機であって、前記金型から突き出された前記成形品を成形品受け取り装置(61)に受け取って前記型開閉方向に対して垂直な方向に取り出す成形品取出装置(6)と組み合わされた射出成形機(1)において、前記成形品の突き出しの際に前記エジェクト装置が前記成形品を突き出すことに加えて前記型締装置が前記金型を前記型開閉方向に開くことによって、前記成形品を前記金型から前記成形品受け取り装置に受け渡すことを主要な特徴とする。   Therefore, in order to solve the above-described problems, the injection molding machine according to the present invention includes a mold clamping device (3) for controlling the movement of the mold (4) in the mold opening / closing direction, and the molded product (11) from the mold. An injection molding machine including an ejecting device (35) projecting in the mold opening / closing direction, wherein the molded product projecting from the mold is received by a molded product receiving device (61) and perpendicular to the mold opening / closing direction. In the injection molding machine (1) combined with the molded product take-out device (6) for taking out in any direction, in addition to ejecting the molded product when the molded product is ejected, the mold clamping device The main feature is that the molded product is transferred from the mold to the molded product receiving device by opening the mold in the mold opening / closing direction.

また、本発明の射出成形機は、金型(4)を型開閉方向に移動制御する型締装置(3)と、成形品(11)を前記金型から前記型開閉方向に突き出すエジェクト装置(35)とを含む射出成形機であって、前記金型から突き出された前記成形品を成形品受け取り装置(61)に受け取って前記型開閉方向に対して垂直な方向に取り出す成形品取出装置(6)と組み合わされた射出成形機(1)において、前記成形品取出装置が前記成形品受け取り装置を前記型開閉方向に移動制御する移動軸を有さない装置に構成され、前記成形品の前記成形品受け取り装置への受け渡し動作が前記エジェクト装置の前記成形品を突き出す動作と前記型締装置の前記金型を前記型開閉方向に開く動作とによって行われても良い。   The injection molding machine of the present invention also includes a mold clamping device (3) for controlling the movement of the mold (4) in the mold opening / closing direction, and an ejecting device (11) for ejecting the molded product (11) from the mold in the mold opening / closing direction. 35), and a molded product take-out device (61) for receiving the molded product protruding from the mold in a molded product receiving device (61) and taking it out in a direction perpendicular to the mold opening / closing direction. 6) In the injection molding machine (1) combined with 6), the molded product take-out device is configured as a device that does not have a moving shaft for moving and controlling the molded product receiving device in the mold opening / closing direction, and The delivery operation to the molded product receiving device may be performed by an operation of projecting the molded product of the ejecting device and an operation of opening the mold of the mold clamping device in the mold opening / closing direction.

また、本発明の射出成形機は、その成形品受け取り装置が前記成形品を吸引して収容する成形品収容ポケット(71)を備え、前記成形品の前記成形品受け取り装置への受け渡し動作が、前記収容ポケットの吸引動作と、前記エジェクト装置の前記成形品を突き出す動作と、前記型締装置の前記金型を前記型開閉方向に開く動作とによって行われても良い。   The injection molding machine of the present invention includes a molded product receiving pocket (71) in which the molded product receiving device sucks and stores the molded product, and the operation of delivering the molded product to the molded product receiving device includes: You may perform by the suction operation of the said storage pocket, the operation | movement which protrudes the said molded product of the said eject apparatus, and the operation | movement which opens the said metal mold | die of the said mold clamping apparatus in the said mold opening / closing direction.

また、本発明の射出成形機は、その成形品受け取り装置が前記成形品を吸着する吸着パッドを備え、前記成形品の前記成形品受け取り装置への受け渡し動作が、前記吸着パッドの吸着動作と、前記エジェクト装置の前記成形品を突き出す動作と、前記突き出し動作に同期する前記金型を前記型開閉方向に開く動作とによって行われても良い。   Further, the injection molding machine of the present invention is provided with a suction pad that the molded product receiving device sucks the molded product, the delivery operation of the molded product to the molded product receiving device, the suction operation of the suction pad, You may perform by the operation | movement which protrudes the said molded article of the said eject apparatus, and the operation | movement which opens the said metal mold | die synchronized with the said protrusion operation | movement in the said mold opening / closing direction.

また、本発明の射出成形機は、前記成形品の前記取り出し動作の直前における前記型締装置の可動プラテン(32)の開き位置は、標準型開位置(O)より前記成形品受け取り装置に近い副型開位置(R)に設定されても良い。   In the injection molding machine of the present invention, the opening position of the movable platen (32) of the mold clamping device immediately before the taking-out operation of the molded product is closer to the molded product receiving device than the standard mold opening position (O). It may be set to the sub mold open position (R).

なお、上記括弧内の符号は、含まれる構成要素を図面と参照するものであり、それらを図面のものだけに限定するものではない。   In addition, the code | symbol in the said parenthesis refers to the component contained in drawing, and does not limit them only to the thing of drawing.

本発明の射出成形機によれば、エジェクト装置による成形品の突き出しの際に射出成形機の型締装置が型開閉方向に開くことによって、成形品取出装置は、その型開閉方向に移動しなくてもその成形品をその金型から成形品受け取り装置に受け取ることができる。それで、成形品取出装置は、型開閉方向に移動しないことによって剛性的にも耐久性においても有利になる。成形品取出装置の型開閉方向の移動軸装置が稼動せずにそのアーム部分の基部近傍に既述されたような曲げモーメント的な負荷がかからないからである。その上、射出成形機が小型である場合には、可動プラテン等の可動部の慣性が小さいことから、可動部の制御性が良好になり、その駆動エネルギも小さくて済む。   According to the injection molding machine of the present invention, when the molded product is ejected by the ejecting device, the mold clamping device of the injection molding machine opens in the mold opening / closing direction, so that the molded product removing device does not move in the mold opening / closing direction. However, the molded product can be received from the mold to the molded product receiving apparatus. Therefore, the molded product take-out device is advantageous in terms of rigidity and durability by not moving in the mold opening / closing direction. This is because the moving shaft device in the mold opening / closing direction of the molded product take-out device does not operate and the bending moment load as described above is not applied in the vicinity of the base portion of the arm portion. In addition, when the injection molding machine is small, since the inertia of the movable part such as the movable platen is small, the controllability of the movable part is improved and the drive energy is small.

また、本発明の射出成形機によれば、成形品取出装置が型開閉方向の移動軸を有さない装置として構成されると共に、エジェクト装置による成形品の突き出しの際に、型締装置が型開閉方向に開くことによって、成形品受け取り装置はその構成が簡単なままで成形品をその金型から受け取ることができる。したがって、その成形品取出装置は、その移動制御軸の省略によって簡素化され小型化されることはもちろんその価格も抑えられる。特に射出成形機が小型である場合には、成形品取出装置の価格が成形機のそれに対して割高になることがより効果的に回避される。   Further, according to the injection molding machine of the present invention, the molded product take-out device is configured as a device that does not have a moving shaft in the mold opening / closing direction, and the mold clamping device is configured to eject the molded product when the ejected device is ejected. By opening in the opening / closing direction, the molded product receiving apparatus can receive the molded product from the mold with its simple structure. Therefore, the molded product take-out device can be simplified and downsized by omitting the movement control shaft, and the price can be reduced. In particular, when the injection molding machine is small, it is more effectively avoided that the price of the molded product take-out device is higher than that of the molding machine.

また、本発明の吸引式の収容ポケットを有する成形品受け取り装置を備えた射出成形機によれば、成形品受け取り装置は、前記成形品の突き出しの際に前記エジェクト装置の突き出し動作と前記型締装置の前記型開閉方向の開き動作とが順次行われることによって成形品を金型から受け取ることができる。それで、その開き動作とその突き出し動作の制御は簡単な順次動作的な制御で済む。   Further, according to the injection molding machine provided with the molded product receiving apparatus having the suction type accommodation pocket of the present invention, the molded product receiving apparatus is configured such that the ejecting operation of the ejecting device and the mold clamping are performed when the molded product is ejected. The molded product can be received from the mold by sequentially performing the opening operation in the mold opening / closing direction of the apparatus. Therefore, the opening operation and the protrusion operation can be controlled by simple sequential operation control.

また、本発明の吸着パッドを有する成形品受け取り装置を備えた射出成形機によれば、前記成形品の突き出しの際に、成形品受け取り装置がスプールをクランプ方式によって受け取る。それで、成形品受け取り装置は、スプールを回収容器に分別回収する際にそれの不測なタイミングでの落下を確実に防止して、結果的にスプールと成形品の混入をより確実に回避する。   Further, according to the injection molding machine including the molded product receiving apparatus having the suction pad of the present invention, the molded product receiving apparatus receives the spool by the clamp method when the molded product is ejected. Therefore, the molded product receiving apparatus reliably prevents the spool from being dropped at an unexpected timing when the spool is separately collected in the collection container, and as a result, the mixture of the spool and the molded product is more reliably avoided.

また、成形品突き出し時の可動プラテンの開き位置が標準型開位置より前記成形品受け取り装置に近い副型開位置に設定される本発明の射出成形機によれば、副型開位置迄の後退距離が短い分だけ時間的・負荷的な無駄が避けられる。   Further, according to the injection molding machine of the present invention in which the opening position of the movable platen at the time of ejecting the molded product is set to the sub mold open position closer to the molded product receiving device than the standard mold open position, the reverse movement to the sub mold open position is achieved. The waste of time and load can be avoided by the short distance.

本発明の射出成形機1は、図1に示されるように、機台2に搭載された型締装置3と、その型締装置3に向かって移動する射出装置5と、型締装置3の近傍、好ましくはその側方に取り付けられた成形品取出装置6とを含む。   As shown in FIG. 1, the injection molding machine 1 of the present invention includes a mold clamping device 3 mounted on a machine base 2, an injection device 5 that moves toward the mold clamping device 3, and a mold clamping device 3. And a molded product take-out device 6 attached in the vicinity, preferably on the side thereof.

型締装置3は、固定プラテン31と可動プラテン32とを備え、可動プラテン32を固定プラテン31に対して移動制御することによって可動側金型42を固定側金型41に対して開閉する。このため、可動プラテン32は、油圧シリンダあるいはサーボモータとボールねじ及びボールねじナットを含む公知の型締駆動装置33によって移動制御される。型締装置3が可動側金型42の開閉を行う方向は、型開閉方向と特定される。   The mold clamping device 3 includes a fixed platen 31 and a movable platen 32, and opens and closes the movable mold 42 with respect to the fixed mold 41 by controlling the movement of the movable platen 32 with respect to the fixed platen 31. For this reason, the movable platen 32 is controlled to move by a known mold clamping drive device 33 including a hydraulic cylinder or servo motor, a ball screw, and a ball screw nut. The direction in which the mold clamping device 3 opens and closes the movable mold 42 is specified as the mold opening / closing direction.

金型41、42から成る金型4には、図1及び図2に示されるように、成形品11を成形するキャビティ43が形成されている。そして、固定側金型41には、ランナ13を介してキャビティ43に連通するスプールブッシュ44が挿嵌されている。それで、溶融樹脂は、射出装置5のノズル51からこのスプールブッシュ44を通して射出されてキャビティ43に充填される。型開き直後の図1で、12はスプールブッシュ44で形成されるスプール、11は成形品、そして13はそれらの間で生ずるランナである。この形態の成形では、ランナ13と成形品11とは固定側金型41に形成されたトンネルゲート45で連通する場合が多い。この場合、金型が開くときにランナ13と成形品11とはこのトンネルゲート45によって切断される。   As shown in FIGS. 1 and 2, a cavity 43 for molding the molded product 11 is formed in the mold 4 including the molds 41 and 42. A spool bush 44 that is in communication with the cavity 43 via the runner 13 is inserted into the stationary mold 41. Thus, the molten resin is injected from the nozzle 51 of the injection device 5 through the spool bush 44 and filled into the cavity 43. In FIG. 1 immediately after the mold opening, 12 is a spool formed by a spool bush 44, 11 is a molded product, and 13 is a runner formed between them. In this form of molding, the runner 13 and the molded product 11 often communicate with each other through a tunnel gate 45 formed in the fixed mold 41. In this case, the runner 13 and the molded product 11 are cut by the tunnel gate 45 when the mold is opened.

可動プラテン32にはエジェクタロッド36を含むエジェクト装置35が設けられ、可動側金型42にはエジェクタプレート47と、これと一体のエジェクタピン46が設けられる。そして、エジェクタプレート47は、通常エジェクタロッド36によって押し出されリターンスプリング48によって押し戻される。それで、成形品11とスプール12はエジェクタピン46によって金型4から突き出される。   The movable platen 32 is provided with an ejecting device 35 including an ejector rod 36, and the movable die 42 is provided with an ejector plate 47 and an ejector pin 46 integral therewith. The ejector plate 47 is normally pushed out by the ejector rod 36 and pushed back by the return spring 48. Therefore, the molded product 11 and the spool 12 are ejected from the mold 4 by the ejector pins 46.

成形品取出装置6は、図1及び図2に示されるように、金型4から突き出された成形品11及びスプール12を受け取る受け取り装置61と、受け取り装置61を先端に有するドライブロッド62と、それを進退させる駆動装置63と、ドライブロッド62に並行に設けられて受け取り装置61の移動の真直性を担保するガイドロッド64と、そのガイド装置65とを少なくとも含み、ブラケット66を介して機台2の側方に固定される。より詳細には、ベース部材61bはドライブロッド62及びガイドロッド64に接続される。ガイド装置65は、例えば丸棒のガイドロッド64を支承する円筒状の直動ボールベアリング軸受として構成される。そして、駆動装置63は、流体シリンダあるいはサーボモータとボールねじ及びナットを含む電動駆動装置から構成される。このような構成の駆動軸装置は、受け取り装置61を前記型開閉方向に対して垂直な方向に移動制御する、従来の取出方向移動軸装置と同じ構成である。   As shown in FIGS. 1 and 2, the molded product take-out device 6 includes a receiving device 61 that receives the molded product 11 and the spool 12 protruding from the mold 4, a drive rod 62 having the receiving device 61 at the tip, It includes at least a drive device 63 that advances and retreats, a guide rod 64 that is provided in parallel with the drive rod 62 and ensures the straightness of movement of the receiving device 61, and a guide device 65, and a machine base via a bracket 66. 2 is fixed to the side. More specifically, the base member 61 b is connected to the drive rod 62 and the guide rod 64. The guide device 65 is configured as, for example, a cylindrical linear motion ball bearing that supports a round guide rod 64. And the drive device 63 is comprised from the electric drive device containing a fluid cylinder or a servomotor, a ball screw, and a nut. The drive shaft device having such a configuration is the same as the conventional take-out direction moving shaft device that controls the movement of the receiving device 61 in a direction perpendicular to the mold opening / closing direction.

受け取り装置61は、可動側金型42のパーティング面に対して略密着する、図3ないし図4に示されるような受け取り部材61aとその背面のベース部材61bとを含み、その受け取り部材61aに、可動側金型42のパーティング面から突き出される成形品11やスプール12を収容して受け取る収容ポケット71、72、あるいは吸着して受け取る図示省略された吸着パッドを備えている。これらの収容ポケット71、72、あるいは吸着パッドは、後に実施例1あるいは実施例2として説明される。   The receiving device 61 includes a receiving member 61a as shown in FIGS. 3 to 4 and a base member 61b on the back surface thereof, which are in close contact with the parting surface of the movable mold 42, and the receiving member 61a includes the receiving member 61a. In addition, there are provided storage pockets 71 and 72 for receiving and receiving the molded product 11 and the spool 12 protruding from the parting surface of the movable side mold 42, or suction pads (not shown) for suction and reception. These accommodation pockets 71 and 72 or suction pads will be described later as Example 1 or Example 2.

以上説明されたこの発明における成形品取出装置6は、従来の取出装置が備えている、受け取り装置を型開閉方向に移動する型開閉方向移動軸装置と、そのための駆動装置とを備えていなくても良いという特徴を有する。また、射出成形機1は、成形品の突き出し時に可動プラテン32をその型開閉方向に移動制御するという特徴を有する。それで、受け取り装置61の型開閉方向の移動動作は、型締装置3の型締駆動装置33による可動プラテン32の型開閉動作によって相対的に制御され、例えば、成形品11等の突き出し時に受け取り装置61を可動側金型42のパーティング面に略密着させる動作は、可動プラテン32側の型開閉動作によって代行される。   The molded product take-out device 6 according to the present invention described above does not include the mold opening / closing direction moving shaft device that moves the receiving device in the mold opening / closing direction and the drive device therefor provided in the conventional take-out device. It has the feature of being good. The injection molding machine 1 has a feature that the movable platen 32 is controlled to move in the mold opening / closing direction when the molded product is ejected. Therefore, the movement operation of the receiving device 61 in the mold opening / closing direction is relatively controlled by the mold opening / closing operation of the movable platen 32 by the mold clamping drive device 33 of the mold clamping device 3, for example, when the molded product 11 or the like is ejected. The operation of bringing 61 substantially into close contact with the parting surface of the movable mold 42 is performed by a mold opening / closing operation on the movable platen 32 side.

上記のような可動プラテン32の開閉制御は、射出成形機1の図示省略された制御装置においてつぎのように制御される。図5には、その制御によって移動制御される可動プラテン32の型開閉方向における動作位置や、成形品取出装置6の取出方向における動作位置を示す線図が示される。   The opening / closing control of the movable platen 32 as described above is controlled as follows by a control device (not shown) of the injection molding machine 1. FIG. 5 is a diagram showing an operation position in the mold opening / closing direction of the movable platen 32 controlled to move by the control and an operation position in the extraction direction of the molded product extraction device 6.

従来の射出成形機の制御装置には図示省略された従来の型開閉設定画面と突き出し設定画面が用意されており、その型開閉設定画面で可動プラテン32の型開閉位置や型締力が設定され、その突き出し設定画面でエジェクト装置35の突き出し動作が設定される。したがって、少なくとも可動プラテン32の標準的な型開位置Oと型閉じ位置Sはその従来の型開閉設定画面で設定される。もちろん、従来の設定画面には、可動プラテン32の型開閉速度の設定欄やエジェクト装置35の突き出し速度の設定欄も用意されている。   A conventional mold opening / closing setting screen and a protrusion setting screen (not shown) are prepared in the control device of the conventional injection molding machine, and the mold opening / closing position and mold clamping force of the movable platen 32 are set on the mold opening / closing setting screen. The ejecting operation of the ejecting device 35 is set on the projecting setting screen. Therefore, at least the standard mold opening position O and mold closing position S of the movable platen 32 are set on the conventional mold opening / closing setting screen. Of course, the setting screen for the mold opening / closing speed of the movable platen 32 and the setting field for the ejection speed of the ejecting device 35 are also prepared on the conventional setting screen.

これに対して、本発明の制御装置には、それらの設定画面に加えて、成形品11等の突き出し及び取り出し時の可動プラテン32の開閉位置を設定する副型開閉設定画面(図示省略されている。)が用意されており、その副型開閉設定画面で成形品11の突き出し時に可動側金型42のパーティング面を受け取り装置61に略密着させる位置が密着位置Cとして設定される。そして、望ましくはその副型開閉設定画面に、受け取り装置61が後退する直前に可動プラテン32が後退している位置である副型開位置Rが設定されると良い。この副型開位置Rは、成形品11等を受け取った受け取り装置61が可動側金型42と干渉することなく後退できる位置であるが、可動プラテン32の移動距離をできるだけ抑えることを意図した位置である。このような副型開閉設定画面とその画面における設定値に従って、成形品取出時の可動プラテン32の型開閉方向への開閉が制御される。なお、副型開閉設定画面でのその型開閉方向への開閉速度については、従来の型開閉設定画面と同様に可動プラテン32の型開閉速度の設定欄が用意されて、それに標準速度に対する割合(%)が設定される。   On the other hand, in addition to these setting screens, the control device according to the present invention sets a sub-type opening / closing setting screen (not shown) for setting the opening / closing position of the movable platen 32 when the molded product 11 and the like are ejected and taken out. The position where the parting surface of the movable mold 42 is brought into close contact with the receiving device 61 when the molded article 11 is projected is set as the contact position C on the sub-die opening / closing setting screen. Desirably, a sub mold opening position R, which is a position where the movable platen 32 is retracted immediately before the receiving device 61 is retracted, is set on the sub mold opening / closing setting screen. The sub-die opening position R is a position where the receiving device 61 that has received the molded product 11 and the like can be retracted without interfering with the movable mold 42, but is a position intended to suppress the moving distance of the movable platen 32 as much as possible. It is. According to such a sub mold opening / closing setting screen and the setting value on the screen, opening / closing of the movable platen 32 in the mold opening / closing direction at the time of taking out the molded product is controlled. As for the opening / closing speed in the mold opening / closing direction on the sub mold opening / closing setting screen, a setting field for the mold opening / closing speed of the movable platen 32 is prepared as in the conventional mold opening / closing setting screen, and a ratio to the standard speed ( %) Is set.

以上説明されたように、受け取り装置61の型開閉方向の移動制御が可動プラテン32の開閉動作によって代替えされることによって、成形品取出装置6は従来の型開閉方向移動軸装置を備えなくても良い。それで、成形品取出装置6はその軸装置が省略される分だけ構造的に簡略化されてその価格も抑えられる。その上、この構成の成形品取出装置6は、既述された曲げモーメント的な負荷を発生することなく、型開閉方向の動作を本来的に高剛性の型締装置によって無理なく行うことができる。そして、特に射出成形機1が小型である場合には、型締装置の可動部の慣性が小さいことから、その制御性や応答性及び省エネルギー性において優れる。特に副型開位置Rが設定される場合には、可動プラテン32の移動ストロークが標準型開位置Oより小さくて済み、成形品取り出しのサイクルがその分だけ短縮される。   As described above, the movement control in the mold opening / closing direction of the receiving device 61 is replaced by the opening / closing operation of the movable platen 32, so that the molded product take-out device 6 does not have the conventional mold opening / closing direction moving shaft device. good. Therefore, the molded product take-out device 6 is structurally simplified by the amount of the shaft device being omitted, and the price can be reduced. In addition, the molded product take-out device 6 having this configuration can perform the operation in the mold opening / closing direction without difficulty by the inherently high-rigid mold clamping device without generating the bending moment load described above. . And especially when the injection molding machine 1 is small, since the inertia of the movable part of the mold clamping device is small, it is excellent in its controllability, responsiveness and energy saving. In particular, when the sub mold opening position R is set, the moving stroke of the movable platen 32 can be smaller than the standard mold opening position O, and the cycle of taking out the molded product is shortened accordingly.

図1、図2及び図5が示すように、機台2の側方には回収容器7が配置される。この取り付け位置の中心は、成形品取出装置6が成形品11等を回収する回収位置P2になる。それで、成形品11の取り出しは、成形品等が突き出される金型4の中心位置である成形品突き出し位置P1とその回収位置P2との間で受け取り装置61を往復することによって行われる。   As shown in FIGS. 1, 2, and 5, a collection container 7 is disposed on the side of the machine base 2. The center of the attachment position is a collection position P2 where the molded product take-out device 6 collects the molded product 11 and the like. Thus, the molded product 11 is taken out by reciprocating the receiving device 61 between the molded product ejection position P1 which is the center position of the mold 4 from which the molded product or the like is ejected and the collection position P2.

以上の受け取り装置61に設けられる収容ポケット又は吸着パッド、成形品を回収する回収容器、及びそれらを使用して成形品を取り出す制御は、以下の実施例でより具体的に説明される。   The storage pocket or suction pad provided in the receiving device 61, the collection container for collecting the molded product, and the control for taking out the molded product using them will be described more specifically in the following embodiments.

図2及び図4に示される成形品受け取り装置61は、その受け取り部材61aに成形品11等を吸引して収容する収容ポケットを備えている。その収容ポケットは、成形品11を収容する成形品収容ポケット71とスプール12を収容するスプール収容ポケット72とからなり、型開きの際に可動側金型42のパーティング面上に出現する成形品11とスプール12の配置位置に対応した位置に形成される。これらの収容ポケット71、72は、成形品11とスプール12を強く吸引するように、それら収容ポケットの入口内側寸法が成形品等の外形寸法より若干大きめの寸法に形成される。また、それらの深さ寸法は、成形品等の長さ寸法より数mm長めに形成される。この数mmの寸法差は、成形品等と収容ポケットとの深さ方向の隙間となる寸法であるが、成形品11等がエジェクタピン46で突き出されるときに金型4から離型する突き出しストローク以上の寸法に形成される。   The molded product receiving apparatus 61 shown in FIG. 2 and FIG. 4 includes an accommodation pocket for sucking and housing the molded product 11 and the like in the receiving member 61a. The storage pocket includes a molded product storage pocket 71 that stores the molded product 11 and a spool storage pocket 72 that stores the spool 12, and a molded product that appears on the parting surface of the movable mold 42 when the mold is opened. 11 and the position corresponding to the arrangement position of the spool 12. These storage pockets 71 and 72 are formed such that the inside dimensions of the entrances of the storage pockets are slightly larger than the external dimensions of the molded product or the like so as to strongly suck the molded product 11 and the spool 12. Moreover, those depth dimensions are formed several mm longer than the length dimension of a molded product or the like. This dimensional difference of several millimeters is a dimension that forms a gap in the depth direction between the molded product and the storage pocket, but the projection that releases from the mold 4 when the molded product 11 or the like is projected by the ejector pin 46. It is formed with dimensions that are greater than the stroke.

深さ寸法をこのように形成することによって、成形品11等の突き出し際に、可動プラテン32を成形品受け取り装置61に密着させたままでエジェクタロッド36を突き出すことができ、エジェクト装置35の突き出し動作と可動プラテン32の開き動作とを順次に行うことができる。こうして、成形品11等の受け取り装置61への受け渡しが確実になると共に副型開閉設定画面における可動プラテン32の型開閉の設定が単純化される。当然、後に実施例2の副型開閉設定画面で説明されるような、エジェクト装置35の突き出し速度と可動金型32の後退速度の同期制御は全く必要ない。   By forming the depth dimension in this way, the ejector rod 36 can be ejected while the movable platen 32 is kept in close contact with the molded product receiving device 61 when the molded product 11 or the like is ejected. And the opening operation of the movable platen 32 can be sequentially performed. Thus, the delivery of the molded product 11 and the like to the receiving device 61 is ensured and the setting of the mold opening / closing of the movable platen 32 on the sub mold opening / closing setting screen is simplified. Naturally, the synchronous control of the ejecting speed of the ejecting device 35 and the retreating speed of the movable mold 32 as described later on the sub mold opening / closing setting screen of the second embodiment is not necessary.

図4に示されるように、成形品収容ポケット71は、通常複数個成形される成形品11の数に合わせて複数個用意される。そして、それらに共通して連通する溝状のチャンバ71bが枠状の1つの溝としてベース部材61bに形成されて、それらの収容ポケット71とチャンバ71bとが透孔71aによってそれぞれ連通する。ベース部材61bにはエアシリンダのシリンダ室のような第一切換室73aを有する第一切換シリンダ73が設けられ、その切換室73aがチャンバ71bに透孔71cを介して連通する。そして、この第一切換室73aが、その側方に取り付けられたエアシリンダ75のピストン75aによって、前室73fと後室73rに区分される。これらの前室73fと後室73rは、空気が吸引される吸引配管と空気が噴出される噴出配管にそれぞれ接続される。   As shown in FIG. 4, a plurality of molded product accommodation pockets 71 are prepared in accordance with the number of molded products 11 that are usually molded in a plurality. A groove-like chamber 71b that communicates with them in common is formed in the base member 61b as one frame-like groove, and the accommodation pocket 71 and the chamber 71b communicate with each other through the through holes 71a. The base member 61b is provided with a first switching cylinder 73 having a first switching chamber 73a such as a cylinder chamber of an air cylinder, and the switching chamber 73a communicates with the chamber 71b through a through hole 71c. The first switching chamber 73a is divided into a front chamber 73f and a rear chamber 73r by a piston 75a of an air cylinder 75 attached to the side thereof. The front chamber 73f and the rear chamber 73r are respectively connected to a suction pipe from which air is sucked and a jet pipe from which air is jetted.

一方、スプール収容ポケット72は、透孔72aを介して第二切換シリンダ74の第二切換室74aに連通する。この切換室74aは、先に説明された第一切換室73aと同様に構成され、エアシリンダ76のピストン76aによって、前室74fと後室74rに区分される。これらの前室74fと後室74rも、同様に吸引配管と噴出配管にそれぞれ接続される。なお、上記透孔71a、72aは、図示省略されたフィルタを含んでいる。   On the other hand, the spool accommodation pocket 72 communicates with the second switching chamber 74a of the second switching cylinder 74 through the through hole 72a. The switching chamber 74a is configured in the same manner as the first switching chamber 73a described above, and is divided into a front chamber 74f and a rear chamber 74r by the piston 76a of the air cylinder 76. The front chamber 74f and the rear chamber 74r are similarly connected to the suction pipe and the ejection pipe, respectively. The through holes 71a and 72a include filters not shown.

これらの収容ポケット71、72は、成形品11やスプール12をエアの吸引によって収容しエアの噴出によって排出する。まず、エアシリンダ75、76のピストン75a、76aの位置が切り換えられて図示のように後退するとき、吸引配管に連通する前室73f、74fが成形品収容ポケット71、スプール収容ポケット72に連通する。それで、それらの収容ポケット71、72は負圧になって成形品やスプールを吸引する。つぎに、ピストン75a、76aが前進するとき、噴出配管に連通する後室73r、74rが収容ポケット71、72に連通する。それでそれらの収容ポケットにエアの噴出が生じて成形品等が外に排出される。吸引と噴出が、このように収容ポケット71、72の直近に設けられた切換弁で切り換えられるので、収容ポケット71、72での成形品等の受け取りと排出が迅速に切換られかつ確実に行われる。   These accommodation pockets 71 and 72 accommodate the molded product 11 and the spool 12 by sucking air and discharging them by ejecting air. First, when the positions of the pistons 75a and 76a of the air cylinders 75 and 76 are switched and retracted as shown in the figure, the front chambers 73f and 74f communicating with the suction pipe communicate with the molded product accommodation pocket 71 and the spool accommodation pocket 72. . Therefore, the receiving pockets 71 and 72 are under a negative pressure and suck the molded product and the spool. Next, when the pistons 75 a and 76 a advance, the rear chambers 73 r and 74 r communicating with the ejection pipe communicate with the accommodation pockets 71 and 72. As a result, air is blown into the receiving pockets, and the molded product is discharged outside. Since the suction and the ejection are thus switched by the switching valve provided in the immediate vicinity of the storage pockets 71 and 72, the receiving and discharging of the molded product and the like in the storage pockets 71 and 72 are quickly switched and performed reliably. .

もちろん、第一切換シリンダ73、第二切換シリンダ74が省略されて透孔71c、72aがそれぞれ一つの配管に連通していても良い。この場合、図示省略されているが、その一つの配管のそれぞれが噴出と吸引とが切り換えられる切換弁に連通し、その切換弁が噴出装置と吸引装置に連通するように構成される。     Of course, the 1st switching cylinder 73 and the 2nd switching cylinder 74 may be abbreviate | omitted, and each of the through-holes 71c and 72a may be connected to one piping. In this case, although not shown in the figure, each of the one pipes is configured to communicate with a switching valve for switching between ejection and suction, and the switching valve is configured to communicate with the ejection device and the suction device.

成形機1の機台2の側面に取り付けられた回収容器7は、図1及び図5で示されるように、中仕切り板によって2つの収容箱に区分され、成形品受け取り装置61に近い位置の1つの収容箱が成形品11を収容する成形品収容箱7aとして、また、それより遠い位置の1つの収容箱がスプール12を収容するスプール収容箱7bとして機能する。そして、これらの収容箱7a、7bは、望ましくは開閉する蓋や昇降する仕切り板等を有し、成形品受け取り装置61から時間差をおいて排出される成形品11とスプール12とを確実に分別回収する。これらの部材は常套的に採用されるもので良いからその図示は省略される。   As shown in FIGS. 1 and 5, the collection container 7 attached to the side surface of the machine base 2 of the molding machine 1 is divided into two storage boxes by a partition plate, and is located near the molded product receiving device 61. One storage box functions as a molded product storage box 7 a that stores the molded product 11, and one storage box farther than that functions as a spool storage box 7 b that stores the spool 12. The storage boxes 7a and 7b preferably have lids that open and close, partition plates that move up and down, and the like, and reliably separate the molded product 11 and the spool 12 that are discharged from the molded product receiving device 61 with a time lag. to recover. Since these members may be conventionally employed, their illustration is omitted.

上記の実施例1において、成形品11等の突き出しの際に可動プラテン32が既述されたように型開閉方向に移動して、突き出された成形品等が受け取り部材61に受け渡される。このため、射出成形機1の制御装置には、既述された副型開閉設定画面が従来の型開閉設定画面及び突き出し設定画面の他に用意されて、その画面で成形品取り出し時の可動プラテン32の開閉位置が設定される。より具体的には、成形品11等の突き出し時に可動側金型42のパーティング面が受け取り装置61に対して略密着する、既述された密着位置Cがあらかじめ設定され、望ましくは、受け取り装置61が成形品11等を受け取った後に金型4と干渉することなく後退する副型開位置Rが更に設定される。特に、この実施例1の副型開閉設定画面での可動プラテン32の型開閉速度は、エジェクト装置35の突き出し速度と同期するように設定される必要はない。   In the first embodiment, the movable platen 32 moves in the mold opening / closing direction as described above when the molded product 11 or the like is ejected, and the ejected molded product or the like is delivered to the receiving member 61. For this reason, the control device of the injection molding machine 1 is provided with the previously described sub mold opening / closing setting screen in addition to the conventional mold opening / closing setting screen and the ejection setting screen, and the movable platen at the time of taking out the molded product on the screen. 32 open / close positions are set. More specifically, the above-described contact position C where the parting surface of the movable mold 42 is substantially in close contact with the receiving device 61 when the molded article 11 or the like is projected is set in advance, and preferably the receiving device. A sub-die opening position R is set which moves backward without interfering with the mold 4 after 61 receives the molded article 11 or the like. In particular, the mold opening / closing speed of the movable platen 32 on the sub mold opening / closing setting screen of the first embodiment need not be set so as to be synchronized with the ejecting speed of the ejecting device 35.

副型開位置Rが設定される場合には、可動プラテン32の後退距離が僅かではあるが短くて済み、その分だけ成形サイクルの短縮化が図れる。ただし、副型開位置Rが省略されてそれが標準型開位置Oで代替えされても良い。この場合、当然可動プラテン32が標準型開位置Oまで後退することになるが、副型開位置Rの設定が不要になり、型開閉制御もその分だけ簡単に済む。   When the sub mold opening position R is set, the retracting distance of the movable platen 32 is small but short, and the molding cycle can be shortened accordingly. However, the sub mold opening position R may be omitted and replaced with the standard mold opening position O. In this case, the movable platen 32 is naturally retracted to the standard mold opening position O, but the setting of the sub mold opening position R is not required, and the mold opening / closing control is simplified accordingly.

以上に説明された実施例1で、成形品の取り出しは、図5の動作図及び図6のフローチャートのように行われる。先に、従来の射出、保圧そして冷却が行われ可動側金型42が標準の型開位置Oまで開かれた後に成形品の取り出しが開始される(スタート)。まず、ドライブロッド62が前進して受け取り装置61が成形品突き出し位置P1まで前進する(ST1)。つぎに可動プラテン32が前進して可動側金型42を既述された密着位置Cで設定された位置まで前進させ、成形品受け取り装置61と可動側金型42とをほぼ密着する(ST2)。つぎにエアシリンダ75、76が作動してピストン75a、76aが移動して、第一切換シリンダ73、第二切換シリンダ74が切換られて収容ポケット71、72の吸引が開始される(ST3)。   In the first embodiment described above, the molded product is taken out as shown in the operation diagram of FIG. 5 and the flowchart of FIG. First, after the conventional injection, pressure holding and cooling are performed and the movable side mold 42 is opened to the standard mold opening position O, the removal of the molded product is started (start). First, the drive rod 62 moves forward and the receiving device 61 moves forward to the molded product ejection position P1 (ST1). Next, the movable platen 32 advances to advance the movable mold 42 to the position set at the contact position C described above, and the molded product receiving device 61 and the movable mold 42 are substantially in close contact (ST2). . Next, the air cylinders 75 and 76 are operated to move the pistons 75a and 76a, the first switching cylinder 73 and the second switching cylinder 74 are switched, and suction of the accommodation pockets 71 and 72 is started (ST3).

つぎにエジェクト装置35はエジェクタロッド36を突き出して成形品11及びスプール12を突き出す(ST4)。すると、成形品11とスプール12はそれぞれ収容ポケット71、72内に吸引されてその奥の底部に当接して吸着される。このとき、収容ポケット71、72が既述された深さ寸法に形成されているので、成形品11等が可動側金型42から離型する前に収容ポケット71、72の底に干渉することはない。   Next, the ejecting device 35 projects the ejector rod 36 to project the molded product 11 and the spool 12 (ST4). Then, the molded product 11 and the spool 12 are respectively sucked into the accommodation pockets 71 and 72 and brought into contact with and adsorbed to the bottom portion at the back. At this time, since the storage pockets 71 and 72 are formed to the above-described depth dimensions, the molded product 11 or the like interferes with the bottoms of the storage pockets 71 and 72 before releasing from the movable mold 42. There is no.

つぎに、例えばエジェクタロッド36の突き出しストロークが検出され、その検出結果から突き出し動作の完了が確認される(ST5)。この完了確認はこの突き出しストロークの監視以外にもいろいろあるが、それらの図示と説明は省略される。この後、エジェクタロッド36が元の位置に後退し(ST6)、つぎに可動プラテン32が後退する(ST7)。このとき可動プラテン32が後退する位置は、簡易には可動側金型42を標準型開位置Oまで後退させる位置であり、好ましくは既述された副型開位置Rである。後退位置が特に副型開位置Rである場合には、可動プラテン32は標準型開位置Oより受け取り装置61に近い副型開位置Rで停止する。   Next, for example, the ejection stroke of the ejector rod 36 is detected, and the completion of the ejection operation is confirmed from the detection result (ST5). There are various completion confirmations other than the monitoring of the protruding stroke, but illustration and explanation thereof are omitted. Thereafter, the ejector rod 36 is retracted to the original position (ST6), and then the movable platen 32 is retracted (ST7). At this time, the position where the movable platen 32 moves backward is simply a position where the movable die 42 is moved backward to the standard mold opening position O, and preferably the sub mold opening position R described above. When the retracted position is the sub mold open position R, the movable platen 32 stops at the sub mold open position R closer to the receiving device 61 than the standard mold open position O.

この後、成形品11等が収容ポケット71、72に存在するかどうかが確認される(ST8)。この在席確認もいろいろな方法によって行われ、例えば、吸引圧力の変化や、光電管による遮光の検出等で確認される。特に在席が検出されない場合には、警報を発して成形を中断する等の異常処理が適宜になされる(ST9)。成形品11等の在席が確認されると、ドライブロッド62が後退して受け取り装置61が回収位置P2まで後退する(ST10)。   Thereafter, it is confirmed whether or not the molded product 11 or the like is present in the accommodation pockets 71 and 72 (ST8). This presence confirmation is also performed by various methods. For example, the presence confirmation is confirmed by detecting a change in suction pressure, light blocking by a photoelectric tube, or the like. In particular, when the presence is not detected, abnormal processing such as issuing an alarm and interrupting molding is appropriately performed (ST9). When the presence of the molded product 11 or the like is confirmed, the drive rod 62 moves backward and the receiving device 61 moves backward to the collection position P2 (ST10).

受け取り装置61が回収位置P2に達すると、収容ポケット71、72の吸引が停止され噴出が開始される(ST12)。一方、可動プラテン32が閉じてつぎの射出工程が再開される(ST11)。噴出への切換は、例えば、つぎのように順番に行われる。まずスプール収容ポケット72にエアが噴出されてスプール12が排出され、つぎに成形品11の収容ポケット71にエアが噴出されて成形品11が排出される。こうして、成形品11とスプール12とは順次排出されて回収容器7に回収される。回収が終了すると噴出が停止され(ST13)、一連の取出動作が終了する(エンド)。   When the receiving device 61 reaches the collection position P2, suction of the storage pockets 71 and 72 is stopped and ejection is started (ST12). On the other hand, the movable platen 32 is closed and the next injection process is restarted (ST11). Switching to the ejection is performed in the following order, for example. First, air is ejected into the spool accommodating pocket 72 and the spool 12 is discharged, and then air is ejected into the accommodating pocket 71 of the molded article 11 and the molded article 11 is ejected. Thus, the molded product 11 and the spool 12 are sequentially discharged and collected in the collection container 7. When the collection is completed, the ejection is stopped (ST13), and a series of extraction operations is completed (end).

以上の射出成形機1において、成形品受け取り装置61は以下のように構成されても良い。ただし、個々の構成は従来公知のものであるからその図示は省略される。成形品受け取り装置61の可動金型42に面する表面には、上記の収容ポケットに代えて、底の浅い、あるいは全く底のない多孔性のパッドが設けられる。そして、その吸着パッドの背面内側にはチャンバが形成され、そのチャンバは、吸着パッド表面での吸着とエアーの噴出の両方を切り換えて行えるように吸引配管と噴出配管の両方に接続される。吸引と噴出の切換装置は既述された実施例1と同様に構成される。一方、スプール12の収容ポケットは、実施例1と同様にスプールが収容される大きさの収容ポケットとして同様に形成されるが、その内部にスプール12を把持するチャックを含むクランプ装置を備えている。   In the above injection molding machine 1, the molded product receiving device 61 may be configured as follows. However, since the individual configurations are conventionally known, illustration thereof is omitted. On the surface facing the movable mold 42 of the molded product receiving apparatus 61, a porous pad having a shallow bottom or no bottom is provided instead of the above-described accommodation pocket. A chamber is formed inside the back surface of the suction pad, and the chamber is connected to both the suction pipe and the jet pipe so that both suction on the suction pad surface and air ejection can be switched. The switching device for suction and ejection is configured in the same manner as in the first embodiment. On the other hand, the storage pocket of the spool 12 is formed in the same manner as the storage pocket of the size in which the spool is stored in the same manner as in the first embodiment, and includes a clamping device including a chuck for gripping the spool 12 therein. .

このような実施例2の成形品受け取り装置61においても、既述された実施例1に準じた成形品11等の突き出し動作が行われてそれらが成形品受け取り装置61に受け渡されるが、特にこの場合には、成形品等の突き出しの際に吸着パッドやクランプ装置が型開閉方向に移動しないことから成形品等を移動させることができない。それで、成形品等は吸着パッドやクランプ装置と共に静止した状態で可動金型42から突き出される必要がある。このため、エジェクト装置35の突き出し速度と可動金型42の後退速度は等しく、より好ましくは全く同期するように制御される。具体的には、記述された副型開閉設定画面に可動プラテン32の型開速度の入力設定欄が用意され、その入力設定欄で少なくとも可動プラテン32の型開速度がエジェクト装置35の突き出し速度に等しく設定できて、結局可動プラテン32の型開速度とエジェクト装置35の突き出し速度とが等しく制御されるように構成される。より好ましくは、その副型開閉設定画面に同期制御のオンオフが切換設定できる入力欄あるいはスイッチが単に用意される方が良い。この場合には、同期制御のオン設定だけで一方の速度が制御装置にフィードバックされて、他方の速度が一方の速度に自動的に追従制御される。   Also in the molded product receiving apparatus 61 of the second embodiment, the protruding operation of the molded article 11 and the like according to the above-described first embodiment is performed and transferred to the molded product receiving apparatus 61. In this case, since the suction pad and the clamp device do not move in the mold opening / closing direction when the molded product or the like is ejected, the molded product or the like cannot be moved. Therefore, the molded product or the like needs to be ejected from the movable mold 42 together with the suction pad and the clamp device. For this reason, the ejecting speed of the ejecting device 35 and the retracting speed of the movable mold 42 are equal, and more preferably controlled so as to be completely synchronized. Specifically, an input setting field for the mold opening speed of the movable platen 32 is prepared on the described sub mold opening / closing setting screen, and at least the mold opening speed of the movable platen 32 is set as the ejection speed of the ejecting device 35 in the input setting field. The mold opening speed of the movable platen 32 and the ejecting speed of the ejecting device 35 are eventually controlled to be equal. More preferably, it is better to simply provide an input field or a switch on the sub-type opening / closing setting screen where the on / off of the synchronous control can be switched. In this case, one speed is fed back to the control device only by setting the synchronous control ON, and the other speed is automatically controlled to follow one speed.

このような実施例2による取り出し動作は、図7のフローチャートのように行われる。まず、ステップST1とST2とが実施例1と同様に行われ、つぎに、吸着パッドによる成形品11の吸着が開始されチャックによるスプール12のクランプが行われる(ST30)。つぎに、可動プラテン32の後退速度とエジェクタロッド36の突き出し速度とが同期制御されて、成形品11とスプール12はあたかも静止しているような状態で可動金型42から突き出される。その結果、成形品11等は移動することなく可動金型42から離型して、成形品11とスプール12とが吸着パッドとチャック装置に受け取られる(ST40)。このとき、可動プラテン32の後退距離とエジェクタロッド3の突き出しストロークは一致している。この後、実施例1と同様に突き出しの完了が確認され(ST5)、エジェクタロッド36が後退すると共に可動プラテンが更に後退して(ST60)、ステップST7からST10までのステップが実施例1と同様に行われる。   The take-out operation according to the second embodiment is performed as shown in the flowchart of FIG. First, steps ST1 and ST2 are performed in the same manner as in the first embodiment. Next, suction of the molded article 11 by the suction pad is started, and the spool 12 is clamped by the chuck (ST30). Next, the retreating speed of the movable platen 32 and the ejecting speed of the ejector rod 36 are controlled synchronously, and the molded product 11 and the spool 12 are ejected from the movable mold 42 as if they were stationary. As a result, the molded product 11 and the like are released from the movable mold 42 without moving, and the molded product 11 and the spool 12 are received by the suction pad and the chuck device (ST40). At this time, the retreat distance of the movable platen 32 and the ejecting stroke of the ejector rod 3 are the same. Thereafter, the completion of the protrusion is confirmed as in the first embodiment (ST5), the ejector rod 36 moves backward and the movable platen further moves backward (ST60), and the steps from step ST7 to ST10 are the same as in the first embodiment. To be done.

ステップ10が行われると、つぎに成形品11等が回収容器7に回収される(ST120)。この成形品11等の回収に際して、チャックによるスプール12のクランプが解かれてアンクランプされる一方で吸着パッドによる成形品11の吸着が停止されてエアーの噴出が開始される。これらのアンクランプと噴出開始は、スプール12と成形品11の分別回収の態様によっていろいろなタイミングで行われる。成形品11とスプール12の分別回収が完了すると噴出が停止され、一連の取り出しが終了する(エンド)。   When step 10 is performed, the molded product 11 and the like are then recovered in the recovery container 7 (ST120). When the molded product 11 or the like is collected, the spool 12 is unclamped and unclamped by the chuck, while the suction of the molded product 11 by the suction pad is stopped and the ejection of air is started. These unclamping and ejection start are performed at various timings depending on the manner of separate collection of the spool 12 and the molded product 11. When the separated collection of the molded product 11 and the spool 12 is completed, the ejection is stopped, and a series of removal is finished (end).

この実施例2では、可動プラテン32の後退速度とエジェクタロッド36の突き出し速度が等しく制御あるいは同期制御されることからその制御に高度性が要求されるが、射出成形機1の型締駆動装置33そのものがそのような制御に適しており、特に問題にはならない。それどころか、成形品11とスプール12の分別回収においては優位な面がある。なぜなら、成形品受け取り装置61は、チャックによってスプール12をクランプして受け取るので、それを回収容器7に排出する際にスプール12の不測なタイミングでの落下を確実に防止して、結果的にスプール12と成形品11の分別回収をより確実にするからである。この場合には、回収容器7は、分別回収のために容器自体を適宜にスライドさせたりあるいは蓋板を開閉する必要がなくなる。   In the second embodiment, since the retreating speed of the movable platen 32 and the ejecting speed of the ejector rod 36 are controlled to be equal or controlled synchronously, a high degree of control is required, but the mold clamping drive device 33 of the injection molding machine 1 is required. As such, it is suitable for such control and is not particularly problematic. On the contrary, there is an advantage in the separate collection of the molded product 11 and the spool 12. This is because the molded product receiving device 61 clamps and receives the spool 12 with the chuck, so that when the molded product receiving device 61 discharges the spool 12 to the collection container 7, the spool 12 is reliably prevented from dropping at an unexpected timing, and as a result, the spool This is because the separation and collection of the molded product 12 and the molded product 11 is further ensured. In this case, it is not necessary for the collection container 7 to slide the container itself appropriately or open and close the lid plate for separate collection.

上記の実施例1及び2において、成形品受け取り装置61は回収容器上で90度旋回するように構成されても良い。この場合、図示が省略されているが、ドライブロッド62やガイドロッド64の先端に旋回ベースが接続され、この旋回ベースに成形品受け取り装置61を90度旋回する回転装置が取り付けられると良い。受け取り装置61がこのように構成されることによって、回収位置P2で受け取り装置61が90度旋回し、まずスプール12を落下させ、つぎに成形品11を落下させてそれらを分離回収することができる。   In the first and second embodiments, the molded product receiving device 61 may be configured to turn 90 degrees on the collection container. In this case, although not shown, it is preferable that a turning base is connected to the distal ends of the drive rod 62 and the guide rod 64, and a rotating device for turning the molded product receiving device 61 by 90 degrees is attached to the turning base. By configuring the receiving device 61 in this way, the receiving device 61 rotates 90 degrees at the collection position P2, and the spool 12 is dropped first, and then the molded product 11 is dropped to separate and collect them. .

以上説明された本発明の射出成形機は、従来の取出機と組み合わせた場合でも利用可能である。従来の取出機であってもその取出方向移動軸装置を使用しないことによって、既述された曲げモーメント負荷による問題点が多いに解消されるからである。また、本発明の射出成形機は、特に小型の射出成形機である場合に特に効果的である。この場合、型締装置の可動部の慣性が小さいことより可動部の型開閉方向の移動制御が高精度に応答良くできるからである。したがって、より効果的には、取出機側で型開閉方向に移動する型開閉方向移動軸が省かれると良い。   The injection molding machine of the present invention described above can be used even when combined with a conventional take-out machine. This is because, even in the conventional take-out machine, by not using the take-out direction moving shaft device, many problems due to the bending moment load described above are solved. The injection molding machine of the present invention is particularly effective when it is a small-sized injection molding machine. In this case, because the inertia of the movable part of the mold clamping device is small, the movement control of the movable part in the mold opening / closing direction can be performed with high accuracy and good response. Therefore, more effectively, the mold opening / closing direction moving shaft that moves in the mold opening / closing direction on the unloader side may be omitted.
