Abstract

PROBLEM TO BE SOLVED: To improve an automatic binder so that the operation of bonding a fine net-shaped object to wire gauze or the like can be done by one operator. SOLUTION: This binder includes: a wire feeder for feeding a binding wire; a guide arm 5 by which the wire curved at its end and fed from the wire feeder is guided so that it is wound in the form of a loop around a part to be bound; a twisting device 6 for twisting and fastening the wound wire by holding one end of the loop; a support arm 7 guiding the loop of the wire to the twisting device 6; and a cutting device for cutting the loop wound. In this case, the guide arm 5 and the support arm 7 have their respective ends sharply pointed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of attaching a fine net-like material (vegetation net) to a wire net or the like in a soil retaining step in a construction work or the like, and binding them together with a wire (wire). And a bonding machine for bonding.

[0002]

2. Description of the Related Art In general, when there is a step between a road and a site in a construction work such as a road, the step is often constructed with a concrete wall. And exposing the soil between the lattices, and planting plants such as turf in the soil. At this time, the inside of the concrete grid
A wire mesh and a vegetation net are arranged in this order to prevent soil from flowing out and to make it easier for the plants to settle.

In the above construction, it is necessary to attach a wire net and a vegetation net. Conventionally, when attaching this fine net to a wire net or the like, two workers are required to use a hacker. A sticking operation was being performed. That is, workers were arranged on both sides of the wire mesh, one worker A sent a binding wire of a predetermined length through the net and the wire mesh to the opposite side, and the other worker B was sent out. The binding wire is grasped, and then pierced again to the opposite side and sent out (at this time, the binding wire is U-shaped and penetrates the net and the wire mesh), and worker A twists both ends of the binding wire with a hacker. Tied together and performed the sticking work.

[0004]

In the above-mentioned work, two workers are required, and two workers need to cooperate with each other with the object to be bound separated. Time and man-hours. Furthermore, in the operation of attaching a net with poor transmittance, the opposite side of the net is not visible, so the binding wire suddenly protrudes through the net, and the worker waiting on one side pierces the protruding binding wire. Was at risk.

[0005] The applicant has proposed a portable binding machine that automatically twists and binds the above binding wires (Japanese Patent Application Laid-Open No. Hei 9-165005). This binding machine,
When the trigger is pulled after inserting the guide arm of the machine into the object to be bound, the binding wire is automatically sent out in a loop and the object to be bound is wound, and the twisting device automatically grips one end of the loop and twists it. It is something to be done. However, the automatic binding machine was not used because it could not be inserted by being hindered by a net and a wire net because the tip of the guide arm was not sharpened.

The present invention improves and provides the above-described automatic binding machine in order to solve the above-mentioned drawbacks and to allow a single person to perform the work of attaching a fine net-like object to a wire netting or the like. That is the subject.

[0007]

In order to solve the above-mentioned problems, a binding machine according to the present invention comprises a wire feeder for sending out a wire for binding and a wire fed from the wire feeder with a curved tip. A guide arm for guiding a loop around the binding portion, a torsion device for gripping and twisting a part of the loop of the wound wire, and a support for guiding the loop-shaped wire to the torsion device In a binding machine provided with an arm and a cutting device for dividing a wound loop, the distal ends of the guide arm and the support arm are formed at sharp points.

[0008]

FIG. 1 shows a binding machine according to the present invention. The binding machine 1 includes a wire 3 disposed behind a main body 2.
, A wire feeding device and a wire cutting device (not shown) disposed in the main body 2 for feeding the wire 3 forward of the main body 2, and guiding the fed wire 3 into a loop 13. A guide arm 5 disposed above the front end of the main body 2 to be twisted, and a support arm 7 disposed below the front end of the main body 2 for guiding the wire 3 guided by the guide arm 5 to the twisting device 6. ing. The distal end 9 of the guide arm 5 is tapered forward,
The top 10 is formed at a point. Similarly, the distal end 11 of the support arm 7 is also tapered forward, and the top 12 is formed at a pointed point. The guide arm 5 is disposed so as to extend further forward than the state in which the wire 3 is guided in a loop shape 13.

Next, the mode of use of the binding machine having the above configuration will be described. First, the binding machine 1 is inserted into the vegetation net 14 and the wire mesh 15 as shown in FIGS. At this time, the net and the wire mesh are inserted from the intermediate portion between the guide arm 5 and the support arm 7 until it comes between the twisting device 6, but the tip portions 9 and 11 of the guide arm 5 and the support arm 7 are formed at the pointed ends. Therefore, when the tops 10 and 12 enter the gaps between the fibers, they can be smoothly inserted into the state shown in FIG. 2 without applying any extra force while expanding or tearing the fibers.

When the trigger 8 is pulled in this state, the wire feeder is driven by a motor (not shown) to feed out the wire 3 wound on the reel 4. The fed wire 3 is given a bending habit by the guide arm 5,
The vegetation net 14 and the wire net 15 sandwiched between the guide arm 5 and the support arm 7 are wound in a loop, guided by the support arm 7 and sent to the guide arm 5 again, and the vegetation net 14 and the The wire mesh 15 is wound around a loop. At this time, the fiber of the vegetation net 14 is expanded and pushed in a direction perpendicular to the direction in which the guide arm 5 and the support arm 7 are inserted, or is torn, or the wire 3 is wound in a loop. When turning, there is no obstacle such as the wire 3 being hooked.

After the winding, the wire 3 is cut by a wire cutting device, one end of the loop 13 is gripped and twisted by the twisting device 6, and the vegetation net 14 is turned on as shown in FIG.
And the wire net 15 are bound.

Thus, the operator inserts the binding machine 1 into the binding target member, makes holes at the sharp distal ends of the guide arm 5 and the support arm 7, and then pulls the trigger to perform automatic binding. In addition, the work conventionally performed by two people can be performed by one person, and the man-hour can be greatly reduced, and the work efficiency is dramatically improved. Also, there is no danger of the worker being injured by the binding wire protruding for one person.

In an environment in which a guide arm of a conventional binding machine cannot be inserted in a binding operation of a wire mesh and a wire mesh, a wire mesh and a reinforcing bar, and a reinforcing bar and a reinforcing bar, it has been conventionally performed manually by a hacker. Since the binding machine of the present invention has the above-described configuration, the binding machine can be applied to such an environment or a complicated place, and the working efficiency can be increased and the physical fatigue can be greatly reduced.

In the above-described embodiment, the binding of the vegetation net and the wire net has been described as the binding object. However, the binding object is not limited to this, and for example, a fine fiber such as a sheet, a net, a cloth, or a net-like material. Also, any sharp end portions of the guide arm and the support arm of the binding machine of the present invention that can be pierced or pierced can be applied.

Further, in the above embodiment, the guide arm and the support arm are fixed to the main body, but the present invention is not limited to this. That is, as described above, the present invention only needs to be able to pierce the object to be bound by piercing the vertically arranged arms. For example, the guide arm and the support arm can be opened and closed (the guide to the object to be bound). The configuration is also applicable to a configuration in which the arm is opened when the arm is inserted, and closed when the wire is wound in a loop, and the distal ends of the guide arm and the support arm are joined to each other.
