〔考案の技術分野〕
本考案は射出成形機等の金型搬送装置に関す
る。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a mold conveying device for an injection molding machine or the like.
従来から射出成形機等においては、短時間に効
率良く金型を交換する必要があり、このため金型
交換装置として金型の搬入搬出用台車がしばしば
使用されている。
Conventionally, in injection molding machines and the like, it is necessary to exchange molds efficiently in a short time, and for this reason, a carriage for carrying in and out of molds is often used as a mold changing device.
このような台車には軌道上を走行するものもあ
れば、軌道外走行するものもあり、走行しない固
定式のものもあるが、最近では金型交換時間の一
層の短縮を計るため、台車上に搬入搬出用の２つ
のステーシヨンを持つた型式のものが多く見うけ
られる。 Some of these types of carts run on tracks, others run off the tracks, and some are fixed types that do not run, but recently, in order to further shorten the mold change time, There are many models that have two stations for loading and unloading.
そしてこれら各ステーシヨンにそれぞれ、金型
を射出成形機内から搬出、あるいは成形機内に搬
入するための駆動装置が具備されている。 Each of these stations is equipped with a drive device for carrying the mold out of or into the injection molding machine.
ところで、その駆動装置には、チエンを案内溝
内で進退させる、いわゆるスネークチエン方式が
あり、チエン先端部に取付けたフツク部を金型と
係合させて金型の搬入搬出を行なうようになつて
いる。また別の方式としては、例えば特公昭55−

取付け金型の搬入搬出を行なつているものがあ
る。 By the way, this drive device has a so-called snake chain method in which the chain is moved forward and backward within the guide groove, and the hook attached to the tip of the chain engages with the mold to carry in and out of the mold. ing. Another method is, for example,
As seen in No. 48535 and Japanese Unexamined Patent Publication No. 54-37060, the conveyor roller is driven and can be rotated forward and backward to carry in and out, and the fixed platen and movable platen in the molding machine are also driven in the same way. Some machines are equipped with rollers to transport molds in and out.
そして成形機内の受ガイドローラ、あるいは駆
動ローラ部と、台車までの受け渡しローラについ
ては、成形機側の受ガイド部を延長したり、また
台車側からローラ付ブラケツトを延長したり、両
者から独立したローラ付架台を設けるなどにより
金型の受け渡しが完全に行なわれるようになつて
いる。 As for the receiving guide roller or drive roller part in the molding machine and the delivery roller to the cart, it is possible to extend the receiving guide part on the molding machine side, extend a bracket with rollers from the cart side, or install a roller that is independent from both. By providing a stand with rollers, etc., the molds can be completely transferred.
以上のように従来例に見られる金型搬送装置
は、ローラを駆動させるための装置を必要とする
が、溝にガイドされたスネークチエン方式などに
より、成形機の型開閉方向に対して直角方向に金
型の搬入搬出を行なつていた。 As mentioned above, conventional mold conveying devices require a device to drive the rollers, but by using a snake chain system guided by grooves, etc. Molds were being brought in and taken out.
すなわち、従来のこれらの金型交換動作をより
具体的に説明すると、はじめに、つぎの成形に使

使用中の金型搬出位置に停車し、台車上の空ステ
ーシヨン側に成形機内の金型を搬出する。 In other words, to explain these conventional mold exchange operations in more detail, first, the mold to be used for the next molding is lifted by a crane from the mold storage and transferred to a trolley near the molding machine. Alternatively, the trolley is carried to the molding machine, stopped at the mold unloading position currently in use with respect to the molding machine, and the mold in the molding machine is transported to the empty station on the trolley.
そして台車に積載されているつぎの成形で使用
する金型を成形機内に搬入するという動作により
金型交換が行なわれている。 The mold is replaced by carrying the mold loaded on the cart into the molding machine to be used for the next molding.
しかして工場のレイアウト上では台車の両側に
成形機を設けることができれば、スペースの有効
活用の面で理想的であるが、チエン牽引方式でこ

の左右いずれの成形機への金型搬入搬出は可能で
あるが、成形機側に必ずローラ駆動装置を設けな
ければならず、したがつて両者ともコスト的に割
高になつてしまう。 However, in terms of factory layout, it would be ideal if molding machines could be installed on both sides of the trolley in terms of effective use of space. A trolley is required, and if the drive roller method is used, it is possible to carry molds into and out of the molding machine on either the left or right side of the trolley, but a roller drive device must be installed on the molding machine side. Both become expensive in terms of cost.
まして小さな成形機においては、成形機内に上
記のような駆動装置を具備することは、スペース
的にも極めて困難であり実用性のないものであつ
た。 Furthermore, in a small molding machine, it is extremely difficult in terms of space and impractical to provide the above-mentioned drive device inside the molding machine.
本考案はこれに鑑み、台車の左右いずれの成形

せる。 First, the trolley 20 of the mold conveying device according to the present invention
is placed next to the molding machine, and the apparatus main body 1 is moved to the overhanging part 24 of the molding machine, so that both the first roller 21, the second roller 23, and the space part 22 are aligned with each other.
つぎに第２ネジ軸７側のモータ１０を駆動して
第２ネジ軸７を回転させる。第２ネジ軸７の回転
と同時に第１ネジ軸６側のモータ１０を駆動し、
第１ネジ軸６を回転させる。 Next, the motor 10 on the second screw shaft 7 side is driven to rotate the second screw shaft 7. Simultaneously with the rotation of the second screw shaft 7, the motor 10 on the first screw shaft 6 side is driven;
The first screw shaft 6 is rotated.
第２ネジ軸７の回転運動は、前記ガイド部材２

第７図および第８図において左側へ進行させるの
で、第２ネジ軸７を支承している支承手段２７の
水平部材２７ａもともに、ガイド部材２８のレー
ル２８ｂに沿つて左進する。 The rotational movement of the second screw shaft 7 is caused by the rotation of the guide member 2.
Since the second threaded shaft 7 is advanced to the left side in FIGS. 7 and 8 by the threaded portion 29 provided in the threaded part 8, the horizontal member 27a of the support means 27 supporting the second threaded shaft 7 is also moved. Move left along the rail 28b of the guide member 28.
また、第１ネジ軸６の回転により、押引具本体
２６を水平部材２７ｂにガイドされながら第１ネ
ジ軸６上を左進し、成形機内の金型１４に近づ
く。 Further, due to the rotation of the first screw shaft 6, the push/pull tool main body 26 moves to the left on the first screw shaft 6 while being guided by the horizontal member 27b, and approaches the mold 14 in the molding machine.
そして押引具２６ｂが金型１４に取付けられて
いる連結片１５に接触する範囲まで近づいた時点
で、押引具２６ｂの先端を起伏させて連結片１５
に係合させる。 When the push/pull tool 26b comes close to contacting the connecting piece 15 attached to the mold 14, the tip of the push/pull tool 26b is raised and lowered, and the connecting piece 15
to engage.
この時点で、第１ネジ軸６、第２ネジ軸７のモ

に搬出される。 At this point, when the motors 10, 10 of the first screw shaft 6 and the second screw shaft 7 are rotated in reverse, the push/pull tool 26b
begins to retreat, and the support means 27 also retreats, so the mold 14 is pulled out onto the first roller 21 and second roller 23 of the apparatus main body 1 and carried out from the overhang 24 onto the carriage 20.
同様に装置本体１につぎに使用する金型がある
ときは、押引具２６ｂと金型の連結片１５を係合
