Patent number: 9197111Abstract: A work output device is revealed. The work output device includes two motor rotors respectively arrange at two ends of a horizontal main rotating shaft. An outer transmission shaft of each motor rotor starts rotating after the power is turned on. The rotating outer transmission shaft drives the main rotating shaft to rotate in one direction through a speed change gear mechanism. The motor rotors are synchronously driven to rotate around the main rotating shaft and move from a lower position to a higher position. At the moment, the power is turned off and the motor rotors turn back from the higher position to the lower position with the help of gravity. Thus a cycle of repetitive up-and-down half circle rotation is completed. Moreover, the main rotating shaft drives a work output shaft to rotate by a torque controller.Type: GrantFiled: November 7, 2013Date of Patent: November 24, 2015Inventor: Jui-An Tsai

Patent number: 6805479Abstract: At least one screw of a screw-type extruder drive-connected via a coupling to a gearing that is driven by a motor, the coupling being able to be coupled to and decoupled from the screw. A gearing carriage is provided which is configured such that the gearing can be drawn by a short distance on the gearing carriage in the direction of the longitudinal axis of the screw in order to decouple the coupling, and which gearing carriage can be swiveled or can move transverse to the longitudinal axis of the screw. The gearing with the coupling can be moved away from the screw to such an extent that the screw can then be withdrawn completely from the extruder counter to the feed direction of the screw, and a screw-changing device is provided by which the existing screw of the extruder can be received and can be replaced by another screw located in the screw-changing device.Type: GrantFiled: May 20, 2002Date of Patent: October 19, 2004Assignee: Berstorff, GmbHInventor: Siegfried Chszaniecki

Publication number: 20040151058Abstract: The invention relates to a method for regulating the minimal value of the pressure in the first half of the metering zone in a direction of conveyance in a single-screw degassing extruder or in a cascade extruder during the conveying of a melt consisting of a thermoplastic. The single-screw degassing extruder or the cascade extruder each have a first screw section (13), a degassing zone (14), a metering zone (22), and a measuring control loop (M), which includes a pressure measuring sensor (P) in the first half of the metering zone, a regulator (R) and an actuator (S) for influencing the pressure in the metering zone. The pressure is measured by the pressure measuring sensor (P) and is set by the regulator (R) and the actuator (S) so that the minimal value at the location of measurement ranges from 0.1 to 10 bar.Type: ApplicationFiled: November 28, 2003Publication date: August 5, 2004Inventors: Bernhard Schafer, Michael Meier-Kaiser

Publication number: 20040076073Abstract: A treatment material agitating and processing apparatus comprises a casing (1) having a supply inlet (13) and a delivery outlet (12) provided therein, an agitator (2) of a screw form arranged to extend lengthwise in the casing (1), and a driving mechanism (3) for driving the agitator (2) to rotate in the casing (1). The agitator (2) repeats a given pattern of its forward and backward rotating actions thus to agitate and convey the treatment material (A) throughout the casing (1). Accordingly, while the duration of the treatment material (A) staying in the casing is favorably determined by the pattern of the forward and backward rotating actions of the agitator (2), the agitated effect of the treatment material (A) can be preset to a desired level by adjusting the rotating speed of the agitator (2).Type: ApplicationFiled: August 21, 2003Publication date: April 22, 2004Inventors: Yaoguang Yao, Kaoru Fujimori, Motonobu Fujimori, Tadao Tishiro

Publication number: 20040013029Abstract: A bread maker having an oven compartment and an electric component compartment, a pair of parallel kneading drums inside the oven compartment that reverse rotary direction periodically and to which are attached opposite ends of a mixing bag containing bread ingredients, and a drum driving part in the electric component compartment rotating the kneading drums. A rotation sensing part senses a rotation rate of one of the kneading drums. A controller stops the drum driving part when the sensed rotation rate is greater than a predetermined rotation rate.Type: ApplicationFiled: December 13, 2002Publication date: January 22, 2004Applicant: Samsung Electronics Co., Ltd.Inventors: Yong-Hyun Kwon, Dong-Bin Lim, Jang-Woo Lee

Patent number: 6632009Abstract: An extruder has a housing and a screw rotatable in the extruder housing about an axis. A drive has a drive housing fixed to the extruder housing, an extension fixed directly to the screw and extending along the axis into the drive housing, and a sleeve-shaped rotor centered on the axis in the drive housing and coaxially surrounding the screw extension. Structure rotation-ally fixes the rotor directly to the screw extension. A sleeve-shaped stator centered on the axis and fixed in the drive housing coaxially surrounds the rotor. The stator and rotor together form a motor that can rotate the screw about the axis.Type: GrantFiled: August 6, 2001Date of Patent: October 14, 2003Assignee: Reifenhauser GmbH & Co.

Publication number: 20030123321Abstract: A method for mixing flowable polymer material with particulate additive utilizes a continuous process. A pre-blend of the polymeric material and additive is made in a hopper. The pre-blend is compacted and fed into a first mixing arrangement to form an intermediate blend. The first mixing arrangement has a rotor with a helical flight located within a chamber. The intermediate blend is fed into a second mixing arrangement to form a final blend. The second mixing arrangement has a conical rotor with blades. The rotors of the first and second mixing arrangements are coaxial but operate at different speeds.Type: ApplicationFiled: November 15, 2002Publication date: July 3, 2003Inventor: Philip Kenneth Freakley

Patent number: 6533447Abstract: A plasticizing apparatus used for a pre-plasticization-type injection molding machine is equipped with a screw drive section which comprises a rotational drive section supported in an axially moveable manner and adapted to rotate the screw; and an advancement/retraction drive section including a servomotor and a ball-screw mechanism for converting rotational motion of the servomotor to linear motion in order to axially move the rotational drive section. By virtue of the above-described structure, the screw disposed within the barrel is rotated by the rotational drive section of the screw drive section, so that the molding material within the barrel is plasticized (melted) and is then supplied to the injection apparatus. Further, the rotational drive section (screw) is advanced and retracted by the advancement/retraction section of the screw drive section, so that the resin passage of the barrel is opened and closed in accordance with the position of the screw.Type: GrantFiled: October 13, 1999Date of Patent: March 18, 2003Assignee: Nissei Plastic Industrial Co. Ltd.Inventors: Atsushi Koide, Jun Nakazawa
