Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rod transfer device for holding a wire rod and applying it to a transmission means to a gripping mechanism provided in a wire rod processing machine.

[0002]

2. Description of the Related Art Conventionally, a wire rod discharged from a wire rod feeder has been transferred to a wire rod processing machine through the operation of a plurality of drive sources.

In some conventional wire rod transfer devices, individual movement sources perform horizontal movement, vertical movement, and 90-degree standing of the wire rod while the wire rod is being transferred. .

[0004]

In order to perform the above operation, the transfer mechanism of the transfer section becomes complicated, and the manufacturing cost is increased.

In view of the above point, the present invention has an object to provide a wire rod transfer device for transferring a wire rod to a wire rod processing machine by one drive source.

[0006]

In order to achieve the above object, in the wire rod transfer device of the present invention, the wire rod is horizontally moved and swung only by the swinging action and transferred to the gripping mechanism of the wire rod processing device. It

A finger for gripping the wire is provided at the outlet of the wire feeder, a swinging lever is connected to the finger, and a holder for linearly guiding the finger is rotatably provided by a relay shaft. Moves horizontally, and further swings so as to swivel and stand up together with the transfer plate and the holder.

Further, the present apparatus is formed so that the wire rod gripped by the fingers matches the gripping mechanism of the wire rod processing machine.

That is, according to the present invention, there is provided a wire rod transfer device which holds a wire rod discharged from the wire rod feeder and has a finger which directly moves in association with an oscillating lever, and which directly moves and swivels. The finger moves in a range (B) until a holder for guiding the transfer plate comes into contact with a finger stopper abutted on the transfer plate by restraint of a spring, while the holder contacts the transfer plate stopper. The wire rod transfer device is characterized in that it can move within the range (A) until it comes into contact, and that the range (A) is smaller than the range (B).

Further, according to the present invention, in the wire rod transfer device, the lever is fixed to a relay shaft provided in the holder, and the swing end of the lever and the finger are connected by a connecting rod. The wire rod transfer device is characterized in that the holder is rotatably provided via a relay shaft, and the lever swings when the relay shaft is rotated by a drive source.

Further, according to the present invention, in the wire rod transfer device, only the fingers move horizontally until the range (BA) is reached, and when the fin gas topper comes into contact with the holder, the fingers are moved. The wire rod transfer device is characterized in that the wire rod transfer device is characterized by swiveling and standing up around the relay shaft via the plate and the holder.

As described above, in the transfer device configured as described above,
The wire rod can be transferred to the wire rod processing machine simply by swinging the lever.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a wire rod transfer device of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of a wire rod transfer device of the present invention. FIG. 3 is a front view showing the basic operation at the time of starting the wire rod transfer device of the present invention in FIG.

As shown in FIGS. 1 and 3, in this apparatus, a finger 2 is provided with a guide block 6, and a guide rail 7 on a transfer plate 5 is moved by the guide block 6 so that the finger 2 rolls. The wire 1 transferred by 22 is guided.

Further, in the finger 2, when the guide block 6 has finished moving to the roll 22 side via the guide rail 7, the finger stopper 12 and the transfer plate 5 via the spring 8 are provided.
However, they abut and are stopped and restrained. On the other hand, the fingers are
The maximum movement range of the finger 2 is moved by moving the range (B) until the holder 9 for guiding the movement of the transfer plate 5 is brought into contact with the finger stopper 13 via the finger stopper 12 which is brought into contact with the transfer plate by the restraint of the spring. Is limited to the range (B).

The guide rail 7 also guides another guide block 6a to which the holder 9 is fixed. The movement of the fingers 2 is smaller than the range (B) by the transfer plate stoppers 14 and 15, the fingers 2 move on the transfer plate, and the transfer plate stopper 1
It is also limited to the range (A) until the holder 9 comes into contact with 5.

Further, the holder 9 is rotatably provided coaxially with the relay shaft 19 for transmitting the power of the drive source 20, and its rotation direction is limited by the holder stoppers 16 and 17.

The swing end 10a of the lever 10 fixed to the end of the relay shaft 19 is connected to the finger 2 via a connecting rod 11.

On the other hand, as shown in FIG. 2, when a coil-shaped wire rod is cut into a certain length by a wire rod feeder 21 (see FIG. 1) and discharged by a roll 22, the wire rod 1 is rolled into a roll 22.
The guide plate 3 provided at the exit of the unit drops it to the top of the V-shape, and the end of the wire is forced by the guide 4.

When the wire 2 is gripped by the fingers 2, as shown in FIG.
The lever 10 starts rotating counterclockwise in the direction opposite to the minute hand of the clock.

By rotating the lever 10 counterclockwise, the fingers 2
Moves along the guide plate 3 and the transfer plate 5 that are in contact with the finger 2 by the spring 8 to the holder 9 side, that is, to the left in the range (A) until it contacts the transfer plate stopper 15.

The fingers 2 and the transfer plate 5 are swivelable, and by moving to the left side, interference with the wall 23 which is a part of the wire rod feeder 21 can be avoided.

When the lever 10 is further rotated, the transfer plate 5 is moved to the transfer plate stopper 1 as shown in FIG.
While stopped by 4, 15, only the finger 2 is pulled by the connecting rod, and the finger stopper 13 is moved to the left until the finger stopper 13 comes into contact with the holder 9, and the range (B) shown in FIG.
Move up to and stop.

Therefore, the wire rod 1 held by the finger 2
Part of the wire appears from the guide plate 3, and the wire rod 1 in the next step
It will be easier to grab.

When the lever 10 is further rotated, as shown in FIG. 6, the fingers 2, the transfer plate 5, and the holder 9 are provided.
Rotates about the relay shaft 19 until it contacts the holder stopper 17 on the substrate 18.

When it comes into contact with the holder stopper 17, the left rotation of the driving source 20 is stopped, and the wire rod 1 is gripped with the gripping mechanism 24 of the wire rod processing machine.

When the wire 1 is transferred to the gripping mechanism 24, the drive source 20 starts rotating to the left, and when the opened finger 2 returns to its original position, the wire 1 is ejected again, and the above operation is repeated. become.

[0029]

Since the wire rod transfer device of the present invention is configured as described above, it is transferred by a plurality of drive sources in the related art, and therefore various mechanisms are required, but one drive source is used. Therefore, the manufacturing cost of the mechanism can be reduced and the moving speed can be increased.
