【World’s First Automatic Wood-Chip Discharging Operation with Actual Cargo】KTN News report

We Iknow Machinery Co., Ltd. is succeed the automatic wood chip discharging operation with actual cargo using by full electric deck crane in late August, 2021 under the huge support and cooperation of Nippon Paper Industries and Nippon Yusen Kabushiki Kaisha. The details are mentioned in the attached file.

We would like to take this opportunity express our appreciation to the shipowner Fukunaga Kaiun Co.,Ltd. and ship management company Misuga Kaiun Co., Ltd.

Then crane installed on the vessel is jib type crane and cargo handling method is luffing cargo handling type
(Fall down the crane jib forward and release the cargo into the hopper).

In case of luffing cargo handling, the pendulum movement of the grab occurs and difficult to release the cargo into the hopper but the point of practical use was the motion control in which the grab was stationary on the hopper could be adopted.

This stationary control is improved and developed of control theory for this project which has been studied for many years in the laboratory of professor Mr.Terashima (current president) of Toyohashi University of Technology and applied for a joint patent with Sinfonia Technology Co., Ltd. and our company.

Our office shall be closed for Summer Holiday from 11th Ougust 2021 to 17th Ougust.

We will be back on 18th Ougust 2021

本年度開発中のチップ船向けクレーン部分自動運転装置の実証試験を今月10日完了した。大島造船所と日本郵船の協力を得て、同造船所で建造中の木材チップ専用船に同装置を搭載して実施。ホールド内部でのグラブの揺れや通信状況などが課題となったが、実験ではいずれも問題なく稼働することを確認し、世界初のチップ船ジブクレーン自動運転実用化に向けて大きく前進した。2021年度後半の実用化を目指す。

木材チップのクレーン荷揚げは、貨物倉の木材チップを専用グラブでつかみ、巻き上げ、上甲板に設置されているホッパーに投入する繰り返し作業。運転者は通常、昼夜交代で作業し、１つのクレーンで２ホールド同時荷揚げを行う場合は約3000回もの繰り返し作業を行う。同社はこれらの荷役作業のうち、中層部の単純で繰り返しの多い作業を、運転者の監視の下で自動化する機能をクレーンに搭載して運転者の負荷低減につなげる。同自動運転装置の開発で、単純作業のうち７～８割が自動化すると見込む。

新開発の自動運転装置は、グラブに装着した３つのセンサーで荷の表面を検知して信号をクレーンに無線送信、グラブが下降し、荷表面に近づくとスピードを落として着地する仕組みだ。また、モヤの発生で荷の表面を目視できないケースを想定し、３つのセンサーで荷の傾斜を検知して、傾斜が過剰である場合はグラブが転倒しないよう着地操作を行うグラブ転倒防止機能も装備。ホッパー満載時はチップ投入を一旦停止しなければならないが、自動運転中はセンサーでホッパーの状態を監視し、自動で待機する機能も持たせた。

We, IKNOW machinery, has introduced KOIKE Fiber Laser Cutting Machine System.
This fiber laser cutting system is different from other laser machines as it provides edge preparation cutting function.
Also, the fiber of the system not only improves the precision of cutting and stabilizes the quality of the products but also reduces the edge preparation process.
In addition, the installation of the printing function enabled the burden on the operator to be reduced and the labors to be saved.
Furthermore, it became possible for us to reduce costs significantly due to it’s scheduling function, which is also one of the merits of the laser cutting machine.
We are delighted to deliver reliable products to customers.
