Description

本発明は、成形品取出装置に関し、特に、プレス機によりプレス成形して成形品を取り出す際、プレス機のプレス速度を速めても、容易に成形品をプレス機外に搬出可能な成形品取出装置に関するものである。   The present invention relates to a molded product take-out apparatus, and in particular, when taking out a molded product by press molding with a press machine, the molded product can be easily taken out of the press machine even if the press speed of the press machine is increased. It relates to the device.

一般的に、プレス機によってプレス成形された成形品を取り出す方法としては、プレス成形後、プレス機内に残された成形品を、プレス機の固定ラムと昇降ラムとの間を進退運動する取り出しアーム先端に固定されたマグネットで吸着して、プレス機外に搬出する方法やエアブローでプレス機から吹き飛ばして搬出する方法等が採用されている。   Generally, as a method of taking out a molded product that has been press-molded by a press machine, a take-out arm that moves the molded product remaining in the press machine between the fixed ram and the lifting ram of the press machine after press molding. A method of adsorbing with a magnet fixed to the tip and carrying it out of the press machine, a method of blowing off from the press machine with air blow, and the like are adopted.

しかしながら、昇降ラムの昇降ストローク量を極力小さくして、プレス機のプレス速度を速める場合、上述したマグネットの吸着による成形品の搬出方法では、プレス機のプレス速度に対応して、取り出しアームの進退速度を速める必要があるが、取り出しアームの進退速度を速めてしまうと、取り出しアーム先端のマグネットに成形品が確実に吸着されず、成形品が昇降ラムの下型上に残ってしまい、成形品を押し潰してしまう虞があった。さらに、このマグネットの吸着による成形品の搬出方法では、マグネットにより金型が磁化していまい、プレス成形後に発生するバリが金型に付着して、次に、プレス成形された成形品に、バリの噛み込みによる傷をつける虞があった。
また、上述したエアブローによる搬出方法では、一回のプレス動作で複数個プレス成形された各成形品を同時に分別して取り出すことが困難であった。 However, when the press stroke of the press machine is increased by making the lift stroke of the lift ram as small as possible, the above-described method of carrying out the molded product by magnet adsorption, the advancement and retreat of the take-out arm corresponding to the press speed of the press machine. Although it is necessary to increase the speed, if the advance / retreat speed of the take-out arm is increased, the molded product will not be securely adsorbed to the magnet at the tip of the take-out arm, and the molded product will remain on the lower mold of the lifting ram. There was a risk of crushing. Furthermore, in this method of carrying out the molded product by magnet adsorption, the mold is magnetized by the magnet, the burrs generated after press molding adhere to the mold, and then the burrs are applied to the press molded product. There was a risk of scratches caused by biting.
Further, in the above-described method of carrying out by air blow, it is difficult to separate and take out each molded product that has been press-molded by a single press operation.

そこで、プレス成形後の成形品を取り出す装置として特許文献１には、プレス機械の被加工物取出装置が開示されている。
すなわち、この特許文献１に開示されたプレス機械の被加工物取出装置は、昇降ラムの型上の被加工物を引っ掛けて被加工物を引き摺り出す被加工物引き摺りヘッドと、被加工物引き摺りヘッドを固定ラムと昇降ラムとのラム空間とその外部との間を運動させる前後運動と被加工物引き摺りヘッドをラム空間内で昇降ラム上の被加工物の上方と被加工物を引っ掛けるように昇降ラムの型上又はそれに近い位置との間を昇降する昇降運動をさせるヘッド駆動手段とを備えている。そして、このプレス機械の被加工物取出装置は、プレス成形されたリング状製品及びスクラップが昇降ラム上の型上に残されると、被加工物引き摺りヘッドをリング状製品及びスクラップの上方をラム空間に向けて、リング状製品及びスクラップを引っ掛ける位置までヘッド駆動手段によって前進運動させて、被加工物引き摺りヘッドをヘッド駆動手段によりリング状製品及びスクラップを引っ掛ける位置まで下降させると共に、被加工物引き摺りヘッドをヘッド駆動手段によって後退運動させて、リング状製品及びスクラップをプレス機械から引き摺り出して、それぞれを搬送手段により所定の位置に導く構成となっている。
特公平７−１２４９９号公報 Therefore, Patent Document 1 discloses an apparatus for taking out a workpiece of a press machine as an apparatus for taking out a molded product after press molding.
That is, a workpiece take-out device for a press machine disclosed in Patent Document 1 includes a workpiece drag head that hooks a workpiece on a lifting ram mold and drags the workpiece, and a workpiece drag head. The ram space between the fixed ram and the lifting ram moves between the ram space and the outside, and the workpiece dragging head moves up and down in the ram space so that the workpiece is hooked above the workpiece on the lifting ram. And a head driving means for moving up and down between the ram mold and a position close thereto. Then, when the ring-shaped product and scrap that have been press-molded are left on the mold on the lifting ram, the workpiece take-out device of this press machine moves the workpiece dragging head from above the ring-shaped product and scrap to the ram space. Toward the position where the ring-shaped product and scrap are hooked by the head driving means, and the workpiece dragging head is lowered to the position where the ring-shaped product and scrap are hooked by the head driving means, and the workpiece dragging head Is moved backward by the head driving means, and the ring-shaped product and scrap are dragged out from the press machine, and each is guided to a predetermined position by the conveying means.
Japanese Patent Publication No.7-12499

しかしながら、上述した特許文献１の発明では、ヘッド駆動手段の構成である、被加工物引き摺りヘッドを前後運動させる前後運動駆動源と、被加工物引き摺りヘッドを昇降運動させる昇降運動駆動源とをプレス機とは別途に設けているために、構造が相当複雑になり、コストアップの要因となる。
また、プレス機の昇降ラムのストローク量を小さくして、プレス速度を速くした場合に、前後運動駆動源及び昇降運動駆動源もプレス速度に対応してその速度を速める必要があるために、その容量を大きくする必要があり、装置自体が大型化してしまう等、更なる問題点が生じる虞がある。
さらに、この特許文献１の発明では、リング状製品及びスクラップを引き摺り出す手段として、被加工物引き摺りヘッドを採用しており、この被加工物引き摺りヘッドでは、例えば、複数の成形品を同時にプレス成形して、各成形品を分別して取り出す際、各成形品をプレス機外に案内する案内面を各成形品に対応して複数備え、さらには、各成形品を対応する各案内面へ導くための手段を備える必要があり、構造が相当複雑化する。 However, in the invention of Patent Document 1 described above, a longitudinal drive source that moves the workpiece dragging head back and forth, and an up / down motion drive source that moves the workpiece dragging head up and down, which are the configuration of the head driving means, are pressed. Since it is provided separately from the machine, the structure becomes considerably complicated, which causes an increase in cost.
In addition, when the stroke speed of the lifting ram of the press machine is reduced and the pressing speed is increased, the forward / backward movement driving source and the lifting / lowering driving source need to increase the speed corresponding to the pressing speed. It is necessary to increase the capacity, which may cause further problems such as an increase in the size of the device itself.
Furthermore, in the invention of Patent Document 1, a workpiece dragging head is employed as a means for dragging out the ring-shaped product and scrap. In the workpiece dragging head, for example, a plurality of molded products are simultaneously press-molded. When separating and taking out each molded product, a plurality of guide surfaces for guiding each molded product to the outside of the press machine are provided corresponding to each molded product, and further, each molded product is guided to each corresponding guide surface. It is necessary to provide this means, and the structure becomes considerably complicated.

本発明は、かかる点に鑑みてなされたものであり、プレス機のプレス速度が速くした場合でも、構造が複雑化することなく、プレス成形後の成形品を確実に外部に取り出すことのできる成形品取出装置を提供することを目的とする。   The present invention has been made in view of such points, and even when the press speed of the press machine is increased, the molded product that can reliably take out the molded product after press molding without complicating the structure. An object is to provide an article take-out device.

Each of the molded product collection boxes 22 has an open top surface and a side wall and a bottom wall formed in a mesh shape so that air can pass through the inside. Each molded product recovery box 22 is installed in each box-shaped member 50, and the other end of each flexible hose 23 is inserted into each box-shaped member 50 and each box-shaped member 50 is suctioned. Each suction device 52 is communicated with each other through the pipe member 51.
Further, as shown in FIG. 1, air is applied to the side of the lower die 6 on the lifting ram 4 of the press 1 slightly above the upper surface of the lower die 6 and in a substantially horizontal direction toward the nozzle portion 20. A pressure feeding device 53 for spraying is arranged.
Each of the suction device 52 and the pressure feeding device 53 introduce each molded product 8a left on the upper surface of the lower mold 6 into each linear passage 21 of the nozzle portion 20 and convey the inside thereof into the press machine 1. This corresponds to the molded product recovery means 17 to be carried out.

次に、本発明の実施の形態に係る成形品取出装置２の動作を、図１〜図３に基いて説明する。
まず、図１に示すように、プレス機１の上型５と下型６との間には、空間が形成されており、この空間内に配された被成形材押え７の下面に近接した位置に、被成形材供給装置より供給された被成形材８が配置される。また、この被成形材８の下方には、ノズル部２０の各直線状通路２１の一端に設けた各開口部２５が下向きになるようにして、且つ、その各開口部２５が下型６の各凹部１１を臨むように配置される。この状態が待機状態となる。 Next, operation | movement of the molded article extraction apparatus 2 which concerns on embodiment of this invention is demonstrated based on FIGS. 1-3.
First, as shown in FIG. 1, a space is formed between the upper die 5 and the lower die 6 of the press machine 1, and is close to the lower surface of the molding material presser 7 arranged in this space. The molding material 8 supplied from the molding material supply device is disposed at the position. Further, below the material 8 to be molded, each opening 25 provided at one end of each linear passage 21 of the nozzle portion 20 faces downward, and each opening 25 is formed on the lower mold 6. It arrange | positions so that each recessed part 11 may be faced. This state is a standby state.

次に、プレス機１を作動させると、図２に示すように、昇降ラム４が上昇すると同時に、被成形材押え７が上型５の下面に近接した位置まで上昇する。
すると、昇降ラム４と共に各ブロック体４８が上昇して、各第２連結アーム４７が、昇降ラム４との固定部４７ａを中心にプレス機１から離間する方向に回動されると共に、各第１連結アーム４６との固定部４７ｂが第１連結アーム４６の軸方向に沿って各スライドコマ４５側にスライドする。
これと同時に、各第１連結アーム４６は、固定ラム３との固定部４６ａを中心にプレス機１から離間する方向に回動されて、各第１連結アーム４６の一端に固定された各スライドコマ４５が各ブロック体４８のレール４９上をプレス機１から離間する方向にスライドし、ノズル部２０の各開口部２５が、上型５と下型６との間の空間からその外部に後退する。
この動作の際には、ノズル部２０の他端に固定された連結部材３６の各管部３８は、各フレキブルホース２３の一端に固定された各円形状管部材３５内にスライド自在に嵌入されているために、ノズル部２０の後退距離は、各円形状管部材３５内で吸収され、各フレキシブルホース２３がノズル部２０の進退方向に大きく揺れることはない。 Next, when the press 1 is operated, as shown in FIG. 2, the elevating ram 4 is raised, and at the same time, the material presser 7 is raised to a position close to the lower surface of the upper die 5.
Then, each block body 48 rises together with the lifting ram 4, and each second connection arm 47 is rotated in a direction away from the press machine 1 around a fixing portion 47 a with the lifting ram 4, and each second The fixing portion 47b with the first connecting arm 46 slides toward the slide pieces 45 along the axial direction of the first connecting arm 46.
At the same time, each first connecting arm 46 is rotated in a direction away from the press machine 1 around a fixing portion 46 a with the fixed ram 3, and each slide fixed to one end of each first connecting arm 46. The top 45 slides on the rail 49 of each block body 48 in a direction away from the press 1, and each opening 25 of the nozzle portion 20 recedes from the space between the upper die 5 and the lower die 6 to the outside. To do.
In this operation, each tube portion 38 of the connecting member 36 fixed to the other end of the nozzle portion 20 is slidably fitted into each circular tube member 35 fixed to one end of each flexible hose 23. Therefore, the retreat distance of the nozzle part 20 is absorbed in each circular pipe member 35, and each flexible hose 23 does not shake greatly in the advancing / retreating direction of the nozzle part 20.

また、プレス機１では、被成形材押え７が上型５の下面に近接した位置で停止された状態であり、被成形材押え７の下面からは、上型５の各ポンチ部１０が相対的に突出するようになる。その後、さらなる昇降ラム４の上昇によって、被成形材８は下型６によって押し上げられると共に、被成形材押え７との間で挟持されつつ、各ポンチ部１０により各成形品８ａが打ち抜かれる。この打ち抜かれた各成形品８ａは、下型６に設けた各凹部１１内に配置される。この状態が被成形材８が各ポンチ部１０で打ち抜かれた瞬間の状態である。   Further, in the press machine 1, the molding material presser 7 is stopped at a position close to the lower surface of the upper mold 5, and each punch portion 10 of the upper mold 5 is relative to the lower surface of the molding material presser 7. Project. Thereafter, as the elevating ram 4 is further raised, the molding material 8 is pushed up by the lower mold 6 and is sandwiched between the molding material presser 7, and each molded product 8 a is punched out by each punch portion 10. Each punched molded product 8 a is disposed in each recess 11 provided in the lower mold 6. This state is a state at the moment when the molding material 8 is punched by the punch portions 10.

次に、図３に示すように、昇降ラム４及び各ブロック体４８が元の位置まで降下すると、各第２連結アーム４７が、昇降ラム４との固定部４７ａを中心にプレス機１に近接する方向に回動されると共に、各第１連結アーム４６との固定部４７ｂが各第１連結アーム４６の軸方向に沿って固定ラム３側にスライドする。
これと同時に、各第１連結アーム４６が、固定ラム３との固定部４６ａを中心にプレス機１に近接する方向に回動されて、各第１連結アーム４６の一端が固定された各スライドコマ４５がプレス機１に近接する方向にブロック体４８上のレール４９をスライドすると共に、ノズル部２０が上型５と下型６との間の空間に前進して、ノズル部２０の各開口部２５が下型６の各凹部１１を臨むように配置された状態で停止する。 Next, as shown in FIG. 3, when the elevating ram 4 and each block body 48 are lowered to their original positions, each second connecting arm 47 approaches the press machine 1 around a fixing portion 47 a with the elevating ram 4. And the fixing portion 47b with each first connecting arm 46 slides toward the fixing ram 3 along the axial direction of each first connecting arm 46.
At the same time, each first connecting arm 46 is rotated in a direction approaching the press machine 1 around a fixing portion 46a with the fixed ram 3 so that one end of each first connecting arm 46 is fixed. While the top 45 slides on the rail 49 on the block body 48 in the direction approaching the press machine 1, the nozzle portion 20 advances to the space between the upper die 5 and the lower die 6, and each opening of the nozzle portion 20 is opened. It stops in a state where the portion 25 is disposed so as to face each concave portion 11 of the lower mold 6.

そして、図３に示すように、下型６の各凹部１１内に配置されていた各成形品８ａは、エジェクタ１２により下型６の上面と略同一面上に突出された状態となっているために、これら各成形品８ａは、各吸引装置５２及び圧送装置５３により、ノズル部２０の各開口部２５から各傾斜面２６に沿って各直線状通路２１に導入される。
さらに、ノズル部２０の各直線状通路２１に導入された各成形品８ａは、主に、各吸引装置５２によって、各フレキブルホース２３内を、各成形品回収箱２２まで搬送されて、プレス機１外に搬出される。そこで、圧送装置５３は、その空気圧によって下型６の上面に残されたバリ等を外部に吹き飛ばす機能も有している。
その後、被成形材押え７の下面に近接して配置された状態のスクラップ８ｂは、被成形材供給装置により図３の紙面方向に搬送されると共に、新しい被成形材８が、被成形材押え７の下面に近接した位置に供給されて、再びプレス機１が作動して、上述した動作が再現される。 And as shown in FIG. 3, each molded product 8a arrange | positioned in each recessed part 11 of the lower mold | type 6 is the state protruded by the ejector 12 on the substantially the same surface as the upper surface of the lower mold | type 6. As shown in FIG. Therefore, these molded products 8 a are introduced into the linear passages 21 along the inclined surfaces 26 from the openings 25 of the nozzle portion 20 by the suction devices 52 and the pressure feeding devices 53.
Further, each molded product 8a introduced into each linear passage 21 of the nozzle portion 20 is mainly conveyed by each suction device 52 to each molded product recovery box 22 through each flexible hose 23 and pressed. It is carried out of the machine 1. Therefore, the pressure feeding device 53 also has a function of blowing away burrs and the like left on the upper surface of the lower mold 6 by the air pressure.
After that, the scrap 8b in the state of being disposed in the vicinity of the lower surface of the molding material presser 7 is conveyed by the molding material supply device in the direction of the paper surface of FIG. 3, and the new molding material 8 is transferred to the molding material presser. 7 is supplied to a position close to the lower surface of 7 and the press machine 1 is operated again to reproduce the above-described operation.

以上説明したように、本発明の実施の形態に係る成形品取出装置２は、特に、プレス機１の昇降ラム４の昇降運動を、ノズル部２０の各直線状通路２１に設けた各開口部２５を上型５と下型６との間の空間とその外部との間を進退させる進退運動に変換させる、駆動手段１６である各第１連結アーム４６及び各第２連結アーム４７を備えているので、昇降ラム４のストローク量を小さくして、プレス速度が速くなった場合でも、ノズル部２０が昇降ラム４の昇降運動に対応しながら進退運動するために、下型６の上面に残された各成形品８ａを、確実にノズル部２０の各直線状通路２１から、各フレキブルホース２３を介して各成形品回収箱２２に搬出させることができる。
また、ノズル部２０を駆動させる駆動手段１６は、モータ等による駆動源を有する構成ではないので、プレス速度を速くした場合でも、構造が複雑化することはない。 As described above, the molded product take-out device 2 according to the embodiment of the present invention particularly has the openings provided in the linear passages 21 of the nozzle portion 20 for the lifting movement of the lifting ram 4 of the press machine 1. The first connecting arm 46 and the second connecting arm 47 which are driving means 16 for converting 25 into an advancing / retreating movement for moving the space 25 between the upper die 5 and the lower die 6 and the outside thereof. Therefore, even when the stroke amount of the elevating ram 4 is reduced and the press speed is increased, the nozzle portion 20 moves forward and backward while responding to the elevating movement of the elevating ram 4, so that it remains on the upper surface of the lower mold 6. Each molded product 8a can be reliably carried out from each linear passage 21 of the nozzle portion 20 to each molded product collection box 22 via each flexible hose 23.
Further, since the driving means 16 for driving the nozzle unit 20 does not have a drive source such as a motor, the structure is not complicated even when the press speed is increased.

さらに、ノズル部２０は、直線状通路２１を複数並設されて構成されており、これら各直線状通路２１が各フレキブルホース２３を介して各成形品回収箱２２に連通されているので、一回のプレス動作で複数プレス成形される各成形品８ａを、分別して各成形品回収箱２２に搬出させることができる。
しかも、下型６の近傍に備えられた圧送装置５３は、各成形品８ａをノズル部２０の各直線状通路２１内に導入させる機能に加え、下型６の上面に残されたバリ等を吹き飛ばす機能も備えているので、次に、プレス成形された成形品８ａにバリ等が噛み込むことはない。 Further, the nozzle portion 20 is configured by arranging a plurality of linear passages 21 in parallel, and each of the linear passages 21 communicates with each molded product recovery box 22 via each flexible hose 23. Each molded product 8 a that is press-molded by a single press operation can be sorted and carried out to each molded product collection box 22.
Moreover, the pressure feeding device 53 provided in the vicinity of the lower mold 6 has a function of introducing each molded product 8 a into each linear passage 21 of the nozzle portion 20, in addition to burrs and the like left on the upper surface of the lower mold 6. Since it also has a function of blowing away, next, burrs or the like do not bite into the press-molded molded product 8a.

なお、本発明の実施の形態に係る成形品取出装置２では、成形品回収手段１７は、各吸引装置５２と圧送装置５３とから構成されることを説明したが、各吸引装置５２が、各成形品８ａを各成形品回収箱２２まで吸引して搬出させると共に、下型６の上面に残されたバリ等も吸引できる吸引力を有していれば、必ずしも、圧送装置５３を設ける必要はない。   In the molded product extraction device 2 according to the embodiment of the present invention, it has been described that the molded product recovery means 17 includes the suction devices 52 and the pumping devices 53. If the molded product 8a is sucked and carried out to each molded product collection box 22 and has a suction force capable of sucking burrs and the like remaining on the upper surface of the lower mold 6, it is not always necessary to provide the pressure feeding device 53.
