Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire body tangle detection device that detects tangles of a wire body disposed between a coil receiver and a wire drawing machine, and more specifically, a wire body supported by the coil receiver. The present invention relates to an apparatus for detecting an entanglement of a striated wire that detects a tangled wire that is drawn from a coil toward a wire drawing machine and transmits a signal by detecting the tangled wire.

Generally, the wire rod drawing apparatus has a configuration as shown in the schematic diagram of FIG.
That is, in FIG. 3, reference numeral 11 indicates a receiving device for the coil 12 in which a wire body (wire) 20 is coiled, and reference numeral 13 indicates a wire drawing machine. The coil receiving device 11 and the wire drawing machine are respectively shown. Reference numeral 13 is fixed on the floor surface 10 by anchor bolts or the like. Between the coil receiving device 11 and the wire drawing machine 13, a smart stand 14 is disposed as a main part of the tangle detection device.

  As shown in FIG. 2, the snare stand 14 has a passage opening 15 for a linear body 20 on the upper end side, and a linear body with a shaft 17 on a machine frame 16 fixed to the floor surface 10 on the base side. It is supported so that it can be tilted in a direction parallel to the traveling direction of 20. The machine frame 16 is provided with a first sensor 18 for detecting that the snare stand 14 is tilted by a certain amount.

  As shown in FIG. 1, the coil receiving device 11 includes a base 21 fixed on the floor 10, a coil fixing portion 22 fixed vertically to the right end of the base 21, and a horizontal to the coil fixing portion 22. A coil receiver (also serving as a wire guide) 23 projecting in the shape of a coil, a flipper 24 attached to the coil receiver 23 so as to be swingable (movable up and down), and a flipper receiver projecting below the coil receiver 23 25.

  In use, the coil 12 is held by the coil receiver 11, and the wire rod 20 is pulled out from the coil 12 by rotation of the wire drawing hook 26 of the wire drawing machine 13 (rotation drive source is a motor not shown). Move toward 13. As a result, the wire body 20 is guided from the coil 12 to the coil receiver (also serves as a wire guide) 23 while being gradually unwound from the coiled state, and is formed on the snare stand 14. It passes through the opening 15 of the strip 20 and reaches the wire drawing machine 13.

  In order to smoothly feed the wire 12 from the coil receiver 11 one coil at a time, the leading end of the coil receiver 23 is set to be higher than the installation position of the first die 27 of the wire drawing machine 13. ing. Further, the center height of the passage opening 15 of the snare stand 14 and the height of the first die of the wire drawing machine 13 are set to be substantially the same.

  In the case where the wire body 20 that has been wound in a coil shape is smooth before the wire body 20 is pulled out from the coil 12 and reaches the wire drawing machine 13, a snail stand is provided. 14 smoothly passes through the passage opening 15 of the linear body 20 formed in 14.

  However, when the striate body 20 is not unwound smoothly in the above-described process, that is, when entanglement remains, the striate body 20 is entangled when passing through the passage opening 15 of the striate body 20. The location is caught in the passage opening 15 and the snare stand 14 is tilted in the traveling direction of the linear member 20. When the snare stand 14 is tilted by a predetermined angle or more, the sensor 18 detects this, and a signal for stopping the operation of the wire drawing device is transmitted by the sensor 18, and the wire drawing device automatically stops the operation by this signal. This operation can prevent the wire body 20 from being disconnected when the tangle occurs.

In the above-described conventional striated device for detecting striate, 100% can be detected when the striate is tangled out of the feeding and jumps out from the coil to the wire drawing machine. When the striated body is tangled and squeezed on the coil receiver, sufficient detection can be achieved with a configuration in which the snare stand is tilted with respect to the traveling direction of the striated body, such as the above-described conventional tangle detection device. There is a problem that it cannot be done.
The present invention is intended to solve such a problem in the conventional tangled body tangle detection device.

  The present invention provides a snare stand as a main part of the entanglement detection unit that can be tilted with respect to the traveling direction of the striate body, while ensuring the same entanglement detection effect as described above, and further -The configuration is such that the passage opening portion of the linear body of the stand is movable upward, and when the linear body is drawn out, the passage opening portion of the linear body of the smart stand is It is an object of the present invention to provide an apparatus for detecting tangling of a striated body that is capable of detecting a case in which the striated body is narrowed by feeding by adopting a configuration that shifts upward.

  Specifically, the present invention is a tangled body entanglement detecting device disposed between a coil receiving device and a wire drawing machine, and the detecting device can be tilted in the traveling direction of the striated body. A snare stand comprising: a supported base portion; and a movable portion which is guided and supported by the base portion so as to be movable upward, and has a passage opening for the above-mentioned striate body on the upper end side. A first sensor for detecting the tilt of the stand, means for holding and restoring the movable part at a normal position, and a second sensor for detecting upward movement of the movable part, To do.

  Further, in the above-described linear body tangling detection device, the base portion is formed of a hollow cylindrical body, and the movable portion is slidably guided and supported by the hollow portion of the base portion.

  Furthermore, in the above-described striated body tangling detection device, the means for holding and restoring the movable portion at a normal position is constituted by an elastic body such as a coil spring or a hydraulic or pneumatic cylinder device.

  In the tangled body entanglement detecting device of the present invention, a snow stand that forms the main part of the detecting device is guided and supported on the base portion so as to be movable upward, and the striated body passes on the upper end side. Since the base portion is supported on the base or the floor so as to be tiltable in the advancing direction of the linear body, the linear body is pulled out from the coil. If the striated body tangled and jumped out before reaching the wire drawing machine, the snare stand column was pulled by the striated body and tilted in the direction parallel to the traveling direction of the striated body. To do. And since it is the structure which a 1st sensor detects this inclination, this tangle can be detected completely.

  Furthermore, since the movable part that forms a part of the snare stand can be moved upward, the movable part is moved upward when the wire is tangled on the coil receiver. Displace. Since the second sensor detects this displacement, it is possible to detect the case where the filament is drawn out.

  As described above, according to the tangled body tangle detection device of the present invention, the striated body is tangled out from the feeding and jumps out from the coil until it reaches the wire drawing machine. Even in cases where the case or the striated object is tangled by being drawn out, the snare stand is tilted or a part thereof is displaced upward. Since this tilt or displacement can be detected by the first and second sensors, the operation of the wire drawing device is automatically stopped by the detection signals of the first and second sensors. It is possible to avoid disconnection due to trouble (entanglement of the striate body) in feeding out the striate body in the wire drawing device.

Hereinafter, the present invention will be specifically described with reference to embodiments shown in the drawings.
FIG. 1 is a partial cross-sectional side view of a linear body entanglement detection device according to an embodiment of the present invention.

  The striated body tangling detection device according to this embodiment is also disposed between the coil receiving device 11 and the wire drawing machine 13 in the striated wire drawing device shown in FIG. Reference numeral 1 denotes a machine frame fixed on the floor 10 of the wire drawing device. In this machine frame 1, the base portion 3 of the snare stand 2 is parallel to the traveling direction of the linear body 20 (see FIG. 3). Further, it is supported by the shaft 4 so as to be tiltable.

  The base portion 3 is formed of a hollow cylinder having a square cross section, and a columnar movable portion 6 having a square cross section in which a passage opening 5 of the linear body 20 is formed on the upper end side in the hollow portion. The guide stand is slidably supported in the direction in which it extends, and a snare stand 2 is formed as the main part of the striated body tangle detection device. While the base portion 3 is formed of a hollow body and the movable portion 6 is formed of a column body that is slidably guided and supported by the hollow portion of the base portion 3, it is possible to ensure the sliding of the movable portion 6 in the vertical direction. The structure of the snare stand 2 can be simplified and the cost can be reduced. Reference numeral 7 denotes a first sensor that detects the inclination of the snare stand 2 provided in the machine casing 1.

The machine frame 1 is provided with a second sensor 8 for detecting the upward movement (extension direction) of the movable part 6, and for holding and restoring the movable part 6 to the neutral position (normal position). A coil spring 9 is interposed between the machine frame 1 and the movable part 6 to hold the movable part 6, that is, the vertical position of the passage opening 5 of the filament 20 at the neutral position (normal position). Alternatively, it can be restored to the neutral position (normal position).
As a means for holding and restoring the movable part at a normal position, an elastic body such as a coil spring 9 is preferable in terms of cost, but a similar effect can be obtained even with a hydraulic or pneumatic cylinder device. it can.

Next, the operation of this apparatus will be described.
The coil 12 is held by the receiving device 11 (see FIG. 3, the same applies hereinafter), and in this state, the coil 12 is rotated from the coil 12 by the rotation of the wire drawing hook 26 of the wire drawing machine 13 (the rotational drive source is not shown). The wire body 20 is pulled out and moved toward the wire drawing machine 13. Then, the wire body 20 is guided from the coil 12 to the coil receiver (also serves as a wire guide) 23 while being gradually unwound in a coiled state, and is formed on the snare stand 2 (FIG. 1). The wire rod 13 passes through the opening 5 of the wire rod 20 that is present.

  In the case where the wire body 20 that has been wound in a coil shape is smooth before the wire body 20 is pulled out from the coil 12 and reaches the wire drawing machine 13, a snail stand is provided. When passing through the passage opening 5 formed in 2, the filament 20 is substantially linear. Therefore, in such a case, the striate body 20 can pass through the passage opening 5 smoothly, and the snare stand 2 does not tilt.

  However, when the filament 20 does not unwind smoothly, that is, when “entanglement” (a state where the coil is entangled) remains, when the filament 20 passes through the passage opening 5. The tangled portion of the linear body 20 is caught in the passage opening 5 and the snare stand 2 is tilted in a direction parallel to the traveling direction of the linear body 20. When the snare stand 2 is tilted more than a predetermined angle, the first sensor 7 detects this, and a signal for stopping the operation of the wire drawing device is transmitted by the first sensor 7, and the wire drawing device automatically operates by this signal. Stop. By this operation, it is possible to prevent the wire body 20 from being disconnected at the time of occurrence of tangles in which the wire body protrudes from feeding.

  Further, in the same process, when the striated member is squeezed by feeding and tangled, when the striated member 20 passes through the passage opening 5, the tangled member of the striated member 20 is caused by this tangling. 2 passing hole 5, that is, the movable body 6 of the snare stand 2 is displaced upward with respect to the floor surface (in the direction of lifting the snail stand). When the movable body 6 is displaced upward by a predetermined length or more, the second sensor 8 detects this, and a signal for stopping the operation of the wire drawing device is transmitted by the second sensor 8, and the wire drawing device is operated by this signal. To stop automatically. By this operation, it is possible to prevent the wire body 20 from being disconnected at the time of occurrence of entanglement in which the wire body is drawn out.

  As described above, according to the striated body tangling detection device of this embodiment, the striated body jumps out from the feeding during the process of pulling out the striated body 20 from the coil 12 and moving it toward the wire drawing machine 13. If the tangles are squeezed into the wire or the striated material by feeding, the first sensor 7 or the second sensor 8 can detect the occurrence of these tangles, and the wire drawing device can be automatically stopped. The disconnection caused by this can be avoided, thereby improving the operating rate. The first sensor 7 or the second sensor 8 can be used regardless of contact type or non-contact type such as a proximity switch or a limit switch.

It is a partial cross section side view of the linear body tangle detection apparatus which concerns on one Embodiment of this invention. It is a partial cross section side view of the conventional linear body tangle detection apparatus. It is the schematic of the wire drawing apparatus of a general linear body.
