- two mold stockers are arranged adjacent to the press machine so that the mold can be carried in or out of the press machine from two directions, for example, the mold can be carried out in one direction from the press machine. At the same time, a new mold can be carried into the press from the other direction. Thereby, the work time for selecting and exchanging a plurality of types of dies is further reduced.
- the molds can be replaced simultaneously at each stage of the press machine, and more molds can be replaced in a short time. Can do.
- the press machine 10 On the upper surface of the base 1 in the die changer for a press machine, there are provided one press machine 10 and two mold stockers 30 arranged adjacent to both the left and right sides of the press machine 10.
- the press machine 10 is a multi-stage type in which a plurality (three) of molds 28 are connected in each opening / closing direction (vertical direction).
- a plurality of types of replacement molds 28 are placed at positions corresponding to the respective stages of the press machine 10. Then, the mold 28 stocked in the mold stocker 30 and the mold 28 at each stage of the press 10 can be exchanged by the cooperation of the transport mechanism T described later.

Abstract
Description
また、プレス機には、例えば特許文献1で開示されているように複数の金型を個々の開閉方向に連ねた多段式があり、この場合には各段の金型を一斉に交換している。
プレス機に対して金型を交換するためのプレス機用金型交換装置であって、プレス機に隣接した位置で回転制御可能に配置され、かつ複数種類の交換用の金型が載せられている金型ストッカーと、この金型ストッカーとプレス機との間において金型を搬送することが可能な搬送機構とを備え、金型ストッカーの回転制御によって選択された金型を搬送機構によってプレス機に搬入あるいは搬出するように構成されている。
また、プレス機に隣接して二つの金型ストッカーが配置され、プレス機に対して二方向から金型の搬入あるいは搬出が行えるようにすることで、例えばプレス機から一方向へ金型を搬出し、これと併行して他方向から新しい金型をプレス機に搬入することができる。これにより、複数種類の金型を選択して交換する作業時間がより短縮される。
さらに、多段式のプレス機を対象として金型ストッカーおよび搬送機構が設けられている場合は、そのプレス機の各段において同時に金型を交換でき、より多くの金型を短時間で交換することができる。
プレス機用金型交換装置におけるベース1の上面には、一つのプレス機10と、このプレス機10の左右両側から隣接して配置された二つの金型ストッカー30とが設けられている。プレス機10は、図1および図5に示されているように複数個(3個)の金型28をそれぞれの開閉方向(上下方向)に連ねた多段式である。また、両金型ストッカー30は、プレス機10の各段に対応する位置において複数種類の交換用の金型28が載せられている。そして、後述する搬送機構Tの協働により、金型ストッカー30にストックされている金型28とプレス機10の各段の金型28とを交換することができる。
後述する金型交換が行われるときのプレス機10は、図5(B)の型締め状態において各ダイプレート18に設けられている上型用クランプ24および下型用クランプ26を開放した後、ダイプレート18A,18B,18Cを上死点まで上昇させた図1あるいは図5(C)で示す状態になる。
前述のようにターンテーブル34を回転させることにより、該ターンテーブル34に載せられている各金型28を、選択的にプレス機10と向き合った出し入れ位置P(例えば図2あるいは図4)に移行させることができる。この出し入れ位置Pの金型28がプレス機10の金型28と交換されることになる。したがって、ターンテーブル34の回転を位置検出センサー38によって検出し、その信号に基づいてモータ36の駆動を制御するようになっている。
なお、上段および中段のターンテーブル34についても、それぞれの出し入れ位置Pの下部にベース1側のフレームが位置しており、そこに個々のストッカー側搬送ユニット60の昇降ブラケット62が昇降可能に支持されている。
プレス機10は図1あるいは図5(C)で示す金型交換状態にあるものとし、各段の金型28は個々のダイプレート18B,18C,18D上でスライド可能である。また、両金型ストッカー30は、それぞれのモータ36の駆動によって回転支柱32の軸心回りに回転させる。これにより、例えば一方の金型ストッカー30においてはターンテーブル34上の交換しようとする金型28を出し入れ位置Pに移動させ、他方の金型ストッカー30においてはターンテーブル34上に金型28が載ってない空きスペースを出し入れ位置Pに移動させる。
以上により、プレス機10の各段において「No.1」の金型28と「No.2」の金型28との交換が完了する。この後、図5(B)で示すようにプレス機10の各ダイプレート18を下降させ、かつ上型用クランプ24および下型用クランプ26によって「No.2」の金型28をクランプすることにより、プレス機10で次工程の加工を続けることができる。
例えば、プレス機10は多段式でなく通常のタイプであってもよく、それによって当然に金型ストッカー30のターンテーブル34も一段で済むことになる。また、二つの金型ストッカー30については、いずれか一方を省略することも可能である。その場合の金型交換には、一つの金型ストッカー30にプレス機10から金型28を搬出し、金型ストッカー30の回転によって交換する金型28を選択し、その金型28をプレス機10に搬入するといった手順を要するが、それでも金型交換の作業効率は従来よりも向上する。
なお、プレス機10の金型28は、金属板等のプレス加工用に限らず、樹脂材の射出成形用であってもよい。
