Patent number: 8378600Abstract: An electric power tool “A” operates a working part 5 by repeating rotation of a motor 4 in a normal direction and in a reverse direction one or more times. The motor 4 includes a brushless motor. Sensors H for detecting a position of a rotor 15 are provided on the motor 4 so as to be advanced by an electrical angle of 30°±?° from an intermediate position between respective stator teeth 16 in a direction of the normal rotation of the rotor 15. A control part 20 for controlling the rotation of the motor 4 controls a driving signal of the motor 4 based on the results of detection by the sensors H. Moreover, the control part 20 selects a detection signal of the sensors H so that relation between the rotor 15 and the detection signal of the sensors H is equivalent in either of the normal rotation and the reverse rotation of the rotor 15.Type: GrantFiled: March 7, 2012Date of Patent: February 19, 2013Assignee: Max Co., Ltd.Inventors: Kouji Katou, Kazuya Takeuchi, Ichiro Kusakari, Osamu Itagaki, Takahiro Nagaoka

Patent number: 8251104Abstract: In a reinforcing bar binder in which a wire reel around which a reinforcing bar binding wire is wound is rotatably housed in a housing chamber in a binder main body, the wire is pulled out from the wire reel and wound around reinforcing bars, and the reinforcing bars are bound by twisting the wound portion, an opening is formed through one of both side walls of the housing chamber at a position corresponding to a shaft receiving portion formed on the wire reel. On the one side wall, a reel receiver which is supported so as to come into and come out from the opening is fitted to the shaft receiving portion of the wire reel when it is pushed into the inside of the side wall. A reel stopper moves along the wall surface of the one side wall and can engage with the reel receiver fitted to the shaft receiving portion. A leaf spring urges the reel stopper engaged with the reel receiver to the pushing-in side.Type: GrantFiled: May 14, 2009Date of Patent: August 28, 2012Assignee: Max Co., Ltd.Inventors: Osamu Itagaki, Ichiro Kusakari, Takahiro Nagaoka

Patent number: 8122916Abstract: A wire reel containing portion 3 of a reinforcing bar binding machine 1 is provided with a rotation detecting lever 8 and a photosensor 7. When a wire reel is rotated in starting to bind a wire, rotation thereof is detected by the rotation detecting lever switched ON/OFF by a projected portion formed at a side face of the wire reel, the photosensor detects a reflection mark of the wire reel to determine a kind of the wire from a number of the marks, and a twist torque or the like is controlled. Wire information is detected not in an initializing operation (in setting wire) of rotating the wire reel at low speed but in a binding operation of rotating at high speed and therefore, an amount of swinging the rotation detecting lever is large and wire information can firmly be detected.Type: GrantFiled: October 13, 2010Date of Patent: February 28, 2012Assignee: Max Co., Ltd.Inventors: Takahiro Nagaoka, Ichiro Kusakari

Patent number: 8033303Abstract: Two guide pins 11 and 12 formed upright in a guide plate 7 are received in guide pin fitting holes 13 and 14 formed in a guide member 8. Fixed screws 23a and 23b are screw-connected to the guide pins 11 and 12. One guide pin 12 is fitted to the corresponding guide pin fitting hole 14 with a play. Screw holes 20 and 21 are formed through the inner surface of the guide pin fitting hole 14 and the outer surface of the guide member 8. An angle of the guide member 8 with respect to the guide plate 7 is adjusted by allowing front ends of embedded screws 22a and 22b respectively screw-inserted in the screw holes 20 and 21 to respectively engage with a peripheral surface of the guide pin 12.Type: GrantFiled: February 20, 2007Date of Patent: October 11, 2011Assignee: Max Co., Ltd.Inventors: Ichiro Kusakari, Takahiro Nagaoka, Osamu Itagaki, Akira Kasahara

Patent number: 7866597Abstract: A reinforcement binding machine (1), comprising a wire reel storage part (3) having a rotation detection lever (8) and a photo sensor (7). When a wire reel is rotated in starting binding, the rotation detection lever is turned on and off by a projected part formed on the side face of the wire reel to detect the rotation, and the photo sensor detects a reflection mark on the wire reel to discriminate the type of the wire by a mark number so as to control torsional torque, etc. Since wire information is detected in binding operation when the wire reel is rotated at a high speed not in initialization operation (in setting the wire) when the wire reel is rotated at a low speed, the swing amount of the rotation detection lever is large and, accordingly, the wire information can be securely detected.Type: GrantFiled: April 27, 2005Date of Patent: January 11, 2011Assignee: Max Co., Ltd.Inventors: Takahiro Nagaoka, Ichiro Kusakari
