[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire entanglement detecting device for detecting entanglement of a wire fed from a drum around which the wire is wound.

[0002]

2. Description of the Related Art Generally, in a wire drawing machine, when a wire having a large wire diameter is drawn, a mechanism for supplying the wire to the wire drawing machine is wound around an outer periphery of a rotatable drum that is rotatably provided. It is known that a drawn wire is pulled out sideways while rotating a rotary drum and is sent to a wire drawing machine side.

[0003]

In the above-described mechanism for supplying a wire, the winding habit is generated when the wound wire is unwound from the rotating drum and pulled out to the side. There is a problem that the wire cannot be pulled out smoothly and tangled. When the wire is entangled in this way, the rotary drum is pulled toward the wire drawing machine, and in some cases, a problem occurs such that the rotary drum falls, so it is necessary to immediately stop the operation of the wire drawing machine. Heretofore, there has been no suitable means for quickly and surely detecting entanglement of a wire rod, and its development has been desired.

[0004] Further , when the entanglement of the wire rod can be eliminated in a short period of time.
If the wire drawing machine is stopped every time,
It is inefficient. The present invention has been made in view of the above circumstances, and its purpose is to be able to quickly and reliably detect entanglement of a wire rod, and to avoid a problem such as a fall of a drum for supplying the wire rod , line
If the tangling of the material is resolved in a short period of time,
An object of the present invention is to provide a wire entanglement detection device that can prevent the operation of the wire rod from being stopped .

[0005]

In order to achieve the above object, the present invention provides a wire entanglement detecting device for detecting entanglement of a wire fed from a drum around which the wire is wound.
It said drum, on the inclined surface inclined upwardly toward the delivery direction of the wire, that is from the middle provided freely <br/> move to come down by its own weight, and this drum is the inclined surface It is provided with a detector for detecting that it has moved upward by a predetermined distance.

[0006]

According to the wire rod entanglement detecting device of the present invention, the wire rod is entangled as the wire rod is sent out from the drum.
If the supply of the wire is not performed smoothly, the drum is pulled in the feeding direction together with the wire, and the detector detects the movement of the drum at a stage where the drum moves upward by a predetermined distance on the inclined surface. On the other hand, when the entanglement of the wire is resolved in a short time,
The drum that has risen to the middle of the slope,
After going down this slope, it returns to its original state.

[0007]

1 and 2 show an embodiment of the present invention.
It will be described based on.

In these figures, reference numeral 1 denotes an inclined table, and four outer edges 2 of the inclined table 1 are formed to protrude upward. Then, the upper surface (inclined surface) of the inclined table 1
Numeral 3 is formed so as to incline upward toward the wire drawing machine (not shown) (to the right in FIG. 2). A carriage 5 is provided movably along the inclined surface 3. A support shaft 6 is provided upright on the traveling vehicle 5, and a rotary drum 7 is rotatably mounted on the support shaft 6. A wire 8 is wound around the outer periphery of the rotary drum 7, and the leading end of the wire 8 is sent to a wire drawing machine (not shown). Further, a detector 9 for detecting the movement of the traveling vehicle 5 is provided on the upper surface 3 of the inclined table 1 on the wire drawing machine side (the right side in FIG. 2).

[0009] In the wire drawing machine provided with the entanglement detecting device configured as described above, if the wire 8 is not properly delivered from the rotary drum 7 and the wire 8 is entangled,
Since the rotary drum 7 is pulled to the wire drawing machine side together with the wire rod 8, the support shaft 6 and the traveling vehicle 5 supporting the rotary drum 7 move to the wire drawing machine side along the inclined surface 3 of the inclined base 1. I do. When the traveling vehicle 5 reaches the upper end of the inclined surface 3, the detector 9 detects this and immediately stops the operation of the wire drawing machine. Therefore, there is no possibility that the rotating drum 7 is pulled further and falls down.

Further, even if the wire 8 becomes entangled, the tangling of the wire 8 may be eliminated in a short period of time. In this case, the traveling vehicle 5 reaches the middle of the inclined surface 3, but the At the stage where the wire rod 8 does not move to the end and the entanglement of the wire rod 8 is resolved ,
The inclined surface 3 due to the weight of the rotating drum 7 and the traveling carriage 5
And return to the original position. Therefore, since the detector 9 does not react and stop the wire drawing machine, the operation of the wire drawing machine is not erroneously stopped despite the state in which the entanglement of the wire 8 is easily eliminated.

[0011]

As has been described above devised, the present invention is, in the entanglement detection device of the wire for detecting the tangle sent from the drum by winding a wire rod wire, the drum, upwardly toward the delivery direction of the wire on the inclined surface inclined, therein
It is provided movably so that it comes down from the belly by its own weight ,
And, since this drum in which detector for detecting that moves over the inclined surface at a predetermined distance upward is provided,
When the wire is entangled with the delivery of the wire from the drum, and the supply of the wire is not smoothly performed, the drum is pulled in the delivery direction together with the wire, and at a stage where the drum is moved a predetermined distance upward on the inclined surface, the detector By detecting the movement of the drum, the entanglement of the wire can be detected quickly and reliably, and the entanglement of the wire is not erroneously detected, and the drum around which the wire is wound is pulled. The problem of falling down can be prevented beforehand.
Furthermore, when the entanglement of the wire is resolved in a short time,
The drum that has risen to the middle of the slope
Down the slope and return to the original position.
The operation of the wire machine can be prevented from being stopped,
A decrease in efficiency can be prevented.
