[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a wire rod cutting device for wire mesh.

[0002]

2. Description of the Related Art The applicant of the present invention has proposed "Kaikai Sho 63-7406," a continuous measuring device for wire. This will be briefly described with reference to FIG. 4. When the wire rod B is fed into the traveling path A and the tip of the wire rod B hits the stopper 10 that has come out downward from the measuring rod 1, the measuring rod 1 also starts to move together and the rear portion of the measuring rod 1 It is cut by running with the shearing blade C of. In the figure, a wire B of length L ₃ is obtained, which is immediately removed from the road A. Since the moved measuring rod 1 compresses the spring 4, the operation of automatically returning by the reaction force of the spring 4 is repeated.

In the prior proposal of FIG. 4, the drive frame 2 for pushing down the stopper 10 is not attached to the measuring rod 1 and does not move.
Placed in. In the conventional device up to that point, each driving member was attached to the measuring rod 1 itself, and therefore the measuring rod 1 became heavy and did not move smoothly.

[0004]

The above-mentioned proposal makes the measuring rod 1 move lighter than the conventional device, but the movement of the measuring rod 1 and the stopper 10 becomes sluggish when it is used for a long time. Came out. As a result of researching this, as in the embodiment of FIG. 4, the engagement portion between the driving body (fluid pressure cylinder) 2 and the stopper 10 is set to the rolling engagement between the pressure roller 7 and the pressure receiving plate 8 and the driving is performed. When the fluid pressure cylinder as the body is returned by the spring 9 as in the conventional case, all the driving bodies 2 always push the pressure receiving plate 8, and particularly the driving body 2 having the stopper 10 lowered is strongly pressed. Only by reducing the lightness of the measuring rod 1 and by compressing the spring 9 having sufficient strength to restore the piston of the fluid pressure cylinder, the pressing force also becomes large, and the pressing force is stopped by the movement of the measuring rod 1. A bending moment was added to 10, and it was clarified that the stopper 10 gradually bends and becomes unstable during use, and based on this clarification, an improvement measure was pursued, and this invention is the present invention.

[0005]

The wire rod cutting device for wire netting of the present invention is provided with stoppers at several positions along the wire rod running path, the stoppers penetrating the rod and moving the tip into and out of the running path. If the tip of the wire rod that is provided and continuously fed hits any of the stoppers, the measuring rod starts to move together with the wire rod, and the shearing blade at the rear of the measuring rod cuts the wire rod by running. The rod stoppers can be pushed in and out of the wire rod entry path by pushing out and pulling back by the respective drive bodies fixed at the corresponding positions of the machine frame. It is characterized in that it is composed of a rectangular plate having an elongated hole and a bifurcated member for axially supporting a pair of rolling elements in the elongated hole at regular intervals by a forked portion sandwiching the rectangular plate.

[0006]

The previous proposal of FIG. 4 uses the return spring 9 which has been used as a return means after the reduction of the driving body (fluid pressure cylinder) attached to the measuring rod 1 itself. However, according to the present invention, this is eliminated, and the driving body performs both pushing and pulling back of the stopper 10. This eliminates the maximum cause of the above-mentioned problems, and further, the engaging portion of each drive member and each stopper is a rectangular plate with an elongated hole, and a bifurcated member that pivotally supports a pair of rolling elements in the elongated hole. Since it is configured as described above, it is impossible to generate a bending moment enough to bend the stopper with a pressing force that merely holds the stopper in the depressed position.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows an embodiment of the present invention in comparison with the prior proposal (FIG. 4), and parts having the same functions are designated by the same reference numerals. As is conventional, the stopper 10 that penetrates the measuring rod 1 at several points along the traveling path A of the wire rod to move the lower end into and out of the traveling path A
When the tip of the continuously fed wire B hits any of the stoppers 10, the measuring rod 1 starts to move together with the wire B, and the shearing blade C at the rear of the measuring rod travels and cuts the wire B. Is.

One of the two points that this device differs from the prior proposal is that
Since each stopper 10 of the measuring rod 1 is driven, each driving body 2 fixed at a corresponding position of the machine frame 6 of the apparatus is driven not only by pressurization as in the conventional case but also by pulling back. This is the point that the return spring 9 is unnecessary. The other is that the engaging portion between the driving body 2 and the stopper 10 is improved as follows.

That is, a rectangular plate 11 having an elongated hole 11a extending along the wire running path A is fixed to the upper end of the stopper 10, and the rectangular plate 11 is attached to the lower end of the rod of the reciprocating hydraulic cylinder which is the driving body 2. Due to the forked part sandwiched, the long hole 1
A bifurcated member 13 for axially supporting a pair of rolling elements (rollers in this case) 12 in 1a at fixed intervals was fixed.

In this way, since the driving body 2 and the stopper 10 are engaged with each other by the pair of rolling elements 12 and the rectangular plate 11 having the elongated hole which receives the rolling elements 12, the wire B hits the stopper 10. Even if the measuring rod 1, each stopper 10 and the rectangular plate 11 thereof mounted on the guide roller 3 move to the positions indicated by the chain lines in FIG. 1, the bending moment to bend the stopper 10 does not occur.

FIGS. 1 and 2 are explanatory views in comparison with FIG. 4, but FIG. 3 is a plan view for production of the present invention, and the wire rod running path A is in the slot of the semi-tubular measuring rod 1 '. The stopper 10 extends from the left and right of the measuring rod 1'to the traveling path A, and the driving body 2 is also on both sides. In FIG. 3, the wire B is abbreviated and only the arrow in the approach direction is shown. Since the wire rod running path A is put in the measuring rod 1 ', the guide and stop of the wire rod are surely performed, and the stopper 1
Since 0s are provided on both right and left sides, wire rods of more types can be obtained. The invention is not limited to the above-mentioned two embodiments, and various changes can be made without changing the gist of the invention.

[0012]

EFFECTS OF THE INVENTION In the present invention, when the idea of the above-mentioned present invention applied by the present applicant is realized, a problem arises when the hydraulic cylinder, which is the conventional driving body, is spring-returned. Clarified. And we have developed a configuration that does not cause problems.

That is, by making the drive body for driving the stopper a reciprocating drive body which does not require a return spring, it does not pressurize the stopper but merely holds it in position, which causes the above-mentioned problems due to the pressurization. lost. Since the engaging portion of the driving body and the stopper is a combination of a rectangular plate with a long hole, a pair of rollers, and a bifurcated member, the stopper holding action of the driving body does not change even if the measuring rod moves.
Bending moments due to springs have also disappeared.
