The device (1) for forming binding elements (2), for winding around at least one element to be bound (3,4) comprises a support structure or framework (5), a forming unit (10) carrying a forming member (11) mobile with respect to the framework (5) between an inoperative position and an operative forming position, a unit (20) for feeding binding elements (2) adapted to be formed in suitable binding means (2') by the forming member when it is activated in the operative forming position.

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 reinforcing bar binding machine is provided with a cutting die (114) having a wire through hole (117) which penetrates through the die along a direction in which a wire (105) is fed out, a blade portion (115a) adapted to move along an open plane (118) of an opening (117a) at one end of the wire through hole (117) to cut a terminating end portion (105b) of the wire (105) which has passed through the wire through hole (117) and an engagement portion (130) adapted to be brought into engagement with a portion of the wire (105) which lies in the vicinity of the terminating end portion (105b) thereof when the blade portion (115a) is rotated so as to bend to hold the portion lying in the vicinity of the terminating end portion. The machine further comprises a first (123), a second (124) and a third guide pin (125), applying a curling tendency to the wire. Said cutting die (114) is disposed between the second and the third guide pin.

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.

A machine for forming a two-stage wire tie around a pair of bars to bind the bars together. The machine comprises an arrangement for passing the wire in a loop around the bars and a twisting head for twisting the ends of the loop together. The twisting head comprises an arrangement for gripping the ends of the wire and a tie plate through which the ends of the wire pass, and the head is resiliently mounted relative to the bars so as to allow the tie plate to move through a predetermined amount of travel towards the bars, to thereby define the length of a first stage of the tie. The machine is adapted thereafter to release the ends of the wire and continue twisting these to form a second stage of the tie.

An apparatus for tying a wire (46) around one or more objects (2) has means for passing said wire in a loop around the objects and means for twisting the ends of said loop together. The twisting means includes at least one gripping means (32) for gripping the wire so that the wire does not slip therethrough. The apparatus also comprises means (54) for applying a biasing force between the twisting means and an object (2) being tied such that as the wire (46) is twisted the twisting means is drawn towards the object (2) against the biasing force.

摘要:
A binding apparatus for binding a wire around one or more objects is provided. The binding apparatus is adapted to bind the wire such that a predetermined tension in the wire is achieved. A method of binding a wire around one or more objects so as to achieve a desired tension of the wire in the binding is also provided.
