BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic tying machine mainly for tying long strips of steel with a tying wire.

[0002]

2. Description of the Related Art Conventionally, a plurality of angle steel materials such as angle materials and H-section steels are bundled with wires and shipped. This binding operation is usually performed by an automatic binding machine. Such an automatic binding machine A is shown in FIG. 5 and will be described briefly. Referring to FIG. 5, the automatic tying machine A includes a tying mechanism 30 for tying the above-mentioned steel bar, and an automatic tying machine main body 10.
And a wire guide mechanism 20 provided on the upper part of the wire. The binding wire W is drawn out of a wire magazine (not shown), guided by the wire guide 21 and the guide wheel 22 of the wire guide mechanism 20, and guided to the binding mechanism 30 from above.

[0003] In order to bind the steel bar, a steel material is inserted into a wire guide ring 31 of the binding mechanism 30, and then a wire W is fed by a wire feeder 32, and the wire W is passed through the wire guide ring 31. It is wrapped around and arranged in a loop. Then, the wire feed portion 32 is reversed, the wire W is drawn, the wire W is removed from the wire guide ring 31, and the wire W is wound around the steel material. After winding the wire W in this manner, the wire twist cutting section 33 twists and cuts the end of the loop of the wire W at the same time.

The reason why the wire guide mechanism 20 is attached to the upper portion of the automatic binding machine main body 10 is that the wire W is easily guided into the binding mechanism 30 due to the structure of the automatic binding machine A. The slack of the excess wire W generated when the wire W is drawn is reduced by the wire guide 21.
This is to allow in the space between the wire magazine.

[0005]

When the wire W is supplied to the automatic binding machine A or when the wire W is exchanged, it is necessary to set the wire W again. That is, it is necessary to pull out the wire W from the wire magazine and guide the wire W to the wire feeder 32 via the wire guide 21 and the guide wheel 22.

However, since the automatic tying machine A has a function of tying a die steel or the like, the height of the wire guide 21 and the guide wheel 22 is more than 2 meters from the base of the automatic tying machine A. For this reason, the work from the base is very dangerous and difficult. Accordingly, an object of the present invention is to provide a wire guide mechanism of an automatic binding machine that can easily and safely set a binding wire from a base of the automatic binding machine.

[0007]

According to a first aspect of the present invention, a wire guide mechanism for an automatic binding machine is provided in an automatic binding machine having a binding mechanism for winding and binding a binding wire around a body to be bound. It has a frame arranged on the upper part of the body of the binding machine, and a wire guide and a guide wheel attached to the frame, and the binding wires sequentially fed from the wire magazine are sequentially passed through the guide wheel and the wire guide. In the wire guide mechanism of the automatic binding machine that guides the binding mechanism from above, the lower part of the frame is hinged to the main body of the automatic binding machine so that the wire guide and the guide wheel can be tilted in the lateral direction of the binding mechanism. It is characterized by having been done.

According to a second aspect of the present invention, there is provided a wire guide mechanism for an automatic binding machine according to the first aspect, wherein a wire guide and a wire guide are provided between the frame and the main body of the automatic binding machine. A damper for gently tilting the guide wheel is interposed.

[0009]

According to the wire guide mechanism of the automatic binding machine of the first aspect, the lower portion of the frame of the wire guide mechanism is hingedly connected to the main body of the automatic binding machine. Can be tilted sideways. Thus, the height of the guide wheel and the wire guide from the base of the main body can be reduced.

Further, according to the wire guide mechanism of the automatic binding machine of the second aspect, the wire guide mechanism is gently tilted by the damper provided on the frame.
