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.

An operation method of a reinforcing bar binding machine includes an initializing operation. During the initializing operation, a cutter of a wire cutting mechanism shuts off a wire passageway, a wire is fed by a wire feed mechanism while the wire passageway remains shut off, and the wire feed mechanism is stopped when a leading end of the wire butts against the cutter.

A rechargeable electric tool includes a warning device which monitors a voltage of a power source battery and indicates a warning by means of an LED or a buzzer when the power source voltage is reduced to be equal to or lower than a reference voltage. The tool is configured such that, even when the warning is indicated, a control to interrupt a power supply to a motor is not performed, thereby enabling a usual operation in response to an activating operation on a trigger switch.

A reverse rotational number of a binding wire feed mechanism is set such that a binding wire is completely pulled back regardless of a boldness or flexibility of the binding wire, a diameter of a reinforcing bar or the like. A driven gear 14 having a V groove of the binding wire feed mechanism is brought into elastic contact with a main drive gear 13 having a V groove by a spring and the binding wire is fed by pinching the binding wire by the main drive gear 13 having the V groove and the driven gear 14 having the V groove. After feeding out the binding wire to form a loop around the reinforcing bar and clamping a front end of the binding wire by a twist mechanism, the binding wire feed mechanism is rotated reversely and the binding wire is pulled back to be wound around the reinforcing bar. After stopping the binding wire, the main drive gear 13 having the V groove and the driven gear 14 having the V groove are slipped relative to the binding wire to rotate idly and continue to rotate reversely until a predetermined rotational number.

A twisting shaft 33 and a remover 34 fitted around the twisting shaft 33 are provided with forks 37, 44 at their respective front portions, and hooks 38 bent from front ends of the forks of the twisting shaft in the forward rotational direction are provided. The remover is rotatable by a one-way stopper mechanism in the forward direction only. When the twisting shaft and remover are rotated forward, a binding wire loop is hung on the hooks 38 and twisted. When the twisting shaft is reversely rotated after the completion of the twisting operation, the remover stops being rotated by the one-way stopper mechanism, and the twisting shaft alone is reversely rotated. As a result, the hooks 38 hide themselves behind the forks 44 of the remover 34, and the binding wire engaged with the hooks 38 is pressed by the forks 44 and removed.

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.

摘要:
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.

A reinforcing bar binding machine is provided with a control unit operated in such a manner that at the time of turning on an electric power source switch, a setting position of a motor drive adjustment dial and a state of a trigger lever are read, and when the motor drive adjustment dial is at a specific setting position and when the trigger lever is turned on, a binding wire cutting mechanism is driven by a predetermined number of times for warming up the binding wire cutting mechanism. When the warming-up operation is carried out in a cold environment, it is possible to reduce the viscosity of grease coated on a mechanism portion. Therefore, it is possible to lower a viscosity of grease applied on a mechanical portion and conduct a reinforcing bar binding work without wasting a binding wire in the same manner as that in a warm environment.

A final gear (23) and a ball screw shaft (24) of a rotation drive system of a binding line twist mechanism are connected by a spline and a shaft portion of a center clamp plate (26) of a binding line clamp apparatus (25) is connected to a front end of the ball screw shaft (24). A shift mechanism for moving the ball screw shaft (24) and the binding line clamp apparatus (25) in a front and rear direction by a slide motor (22) is provided. A wire (W) is wound around a reinforcing bar (S) by a binding line feed mechanism, the wire is grasped by a front end portion of the binding line clamp apparatus (25) and thereafter, a shift mechanism applies a tension to a loop of the wire by moving rearward the binding line clamp apparatus (25). The binding line clamp apparatus (25) is rotated by a twist motor (21) and the shift mechanism twists up the wire by moving forward the binding line clamp apparatus (25). Since the wire is applied with the tension and twisted, a reinforcing bar binding strength of the wire loop is stabilized.
