Publication number: 20190161296Abstract: There is provided with a feeding apparatus that feeds sheets to an apparatus serving as a feeding destination. A sheet storage unit stores the sheets and be able to be pulled out from the feeding apparatus. A stacking unit stacks the sheets. A detection unit detects a connected state and a separated state. A control unit places the sheet stacked on the stacking unit at the predetermined height when the detection unit detects the connected state. A control unit lowers the stacking unit so as to place the sheet at the predetermined height stacked on the stacking unit to a position lower than the predetermined height in accordance with detection of a change from the connected state to the separated state by the detection unit.Type: ApplicationFiled: November 20, 2018Publication date: May 30, 2019Inventor: Shin Iwasaki

Publication number: 20170334117Abstract: This pelletizer apparatus includes an observation unit for observing, from the outside of a housing chamber, a cut section of a synthetic resin cut by cutting teeth inside the housing chamber. The observation unit includes an optical system which sends an optical image of the cut section from the inside of the housing chamber to the outside of the housing chamber. Thus, with this pelletizer apparatus, the cut section can be visually checked clearly via the optical system.Type: ApplicationFiled: October 5, 2015Publication date: November 23, 2017Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Chitaka MANABE, Kaname ARAKI, Eiji TAKAHASHI, Shin IWASAKI

Patent number: 9333674Abstract: The present invention provides kneading/extruding equipment capable of stable operation by keeping the pressure of kneaded material before a first-stage gear pump in steady operation (molding) and preventing fluctuation of the pressure of kneaded material before the first-stage gear pump constant from largely affecting the pressure of kneaded material before a latter-stage gear pump at start-up or upon change of production rate, and thus capable of responding to an increase in production rate while securing a high-quality molded product, and an operation control method thereof. The kneading/extruding equipment comprises: a rotational speed feedback control unit for a first gear pump, which feedback-controls the rotational speed of the first gear pump, and a rotational speed feedforward control unit for a second gear pump, which feedforward-controls the rotational speed of the second gear pump.Type: GrantFiled: February 5, 2013Date of Patent: May 10, 2016Assignee: Kobe Steel, Ltd.Inventors: Shinichi Asagiri, Satoshi Abe, Shin Iwasaki, Yoshinori Kuroda, Kazuo Iritani, Kayoko Minami

Patent number: 8727761Abstract: A die for an underwater cutting type pelletizer, the die including a die orifice part in which a thermoplastic resin is inhibited from solidifying within the die orifices. The die can have a reduced difference in temperature between the die orifice part and an inner periphery-side fixing part for fixing the die orifice part to a mixer/extruder, and can thereby inhibit the generation of thermal stress. The die is characterized by being equipped with a heating jacket for heating the inner periphery-side fixing part, the heating jacket being disposed within the inner periphery-side fixing part along an inner annular passage formed within either the die orifice part or the inner periphery-side fixing part or both along the boundary between the die orifice part and the inner periphery-side fixing part.Type: GrantFiled: December 10, 2009Date of Patent: May 20, 2014Assignee: Kobe Steel, Ltd.Inventors: Kazuo Iritani, Shin Iwasaki, Nobuki Nagami

Patent number: 8602762Abstract: In a resin granulating apparatus of the present invention, a bracket extending in the outward radial direction over an outer peripheral surface of a sleeve is provided for the sleeve for rotatably supporting a cutter shaft of a cutter for shearing a material extruded from a die. Stopper means cooperating with the bracket to regulate movement of the sleeve toward the die and moving a regulation position in the axial direction is provided on the radially outer side over an outer diameter of the sleeve. With such a configuration, installation space is compactified so as to additionally provide the stopper means in the existing facilities, and a position of the cutter relative to a die surface is precisely adjusted so as to stably produce a pellet of a best shape.Type: GrantFiled: March 5, 2010Date of Patent: December 10, 2013Assignee: Kobe Steel, Ltd.Inventors: Keizo Arita, Yasuo Yoshii, Kazuo Iritani, Osamu Ikeda, Yoshiaki Nakata, Shin Iwasaki

Publication number: 20130042738Abstract: Provided is a knife holder (10) for use with an underwater cutting pelletizing device which includes a die plate (40) and the knife holder (10). The die plate (40) includes an annular projected portion (52) and a plurality of die holes (51) having an opening on the projected portion (52). The knife holder (10) holds a plurality of knives (30) which slide on the surface of the projected portion (52) to thereby cut melt resin, which has been pushed through each of the die holes (51), into resin pellets in cooling water. The knife holder (10) can reduce the deflection of the knife (30) and thereby the gap that appears between the sliding plane thereof and the die plate projected portion (52). The knife holder (10) includes a knife holder body (11) and a plurality of rib portions (12). The knife holder body (11) has an outer circumference end (11a) which is located inside the inner circumference end of the projected portion (52) of the die plate (40) in the radial direction.Type: ApplicationFiled: June 3, 2011Publication date: February 21, 2013Applicant: KABUSHIKI KAISHA KOBE SEIKO SHO (Kobe Steel, Ltd.)Inventors: Shin Iwasaki, Kazuo Iritani, Yoshiaki Nakata
