Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire feeding device for feeding a wire from a coiled wire.

2. Description of the Related Art In the manufacturing process of wires made of metals such as steel, copper, and aluminum, scraping is performed to thinly peel off the outer skin of the wires in order to remove flaws, oxide films, foreign substances, and the like on the surfaces of the wires. This debarking is performed by arranging a debarking device between a wire feeding device that supports the coiled material wound in a coil shape and a winding device that winds up the wire. The wire rod is shaved by the scraping device while the reeled-out wire rod is wound by the winding device.

When the wire is wound in a coil shape, the coil material has a local bend or a part where the wire materials are entangled with each other. As a result, the wire is not fed out smoothly, and the tension (feeding force) acting on the wire increases, resulting in wire breakage and the wire feeding device being pulled by the wire and being displaced. Therefore, it has been proposed to provide a damper that absorbs fluctuations in the drawing-out force acting on the drawn-out wire to prevent wire breakage due to an increase in the drawing-out force of the wire (for example, Patent Document 1).

In addition, as a wire rod feeding device for metal wire rods, a type in which the axis of the coil rod is vertically supported is often adopted. The actual situation is that no arrangement structure has been proposed. Furthermore, if the wire rod feeding device is displaced beyond the permissible range due to fluctuations in the feeding force, the wire rod will not be properly supplied to the device (bark scraping device, etc.) downstream in the wire feeding direction, resulting in quality problems. However, Patent Document 1 does not give any consideration to positional deviation of the wire feeding device.

It is configured to be biased in a direction away from the delivery portion S (opposite to the moving direction of the carriage 21 due to the delivery force). In addition, the first air cylinder 28 is below the coil material 13 supported by the supply stand 22 positioned at the wire rod feeding portion S, and the carriage 21 is located between the wire rod feeding portion S and the first coil loading portion S1 ( It is arranged at a position where it does not come into contact with the carriage 21 when it moves to and from the second coil loading section S2). Further, the first air cylinder 28 is positioned on the rear side of the carriage 21 positioned in the wire feeding portion S, and pushes the wire rod 12 fed forward of the carriage 21 from the coil material 13 loaded on the supply reel 24 . It is designed not to face the delivery path.

As shown in FIGS. 5 and 6, the first rod 28b of the first air cylinder 28 has a rod body 28c extending along the first cylinder 28a and a rectangular connecting block 28d. The connecting block 28d is provided at the end of the rod body 28c. The connecting block 28d is provided with an elongated hole 28e that penetrates in the vertical direction and extends along the extending direction of the rails 20, 20 as an opening through which a pin 34, which will be described later, can be inserted. Further, rollers 30, 30 are rotatably supported by the first rod 28b, and the rollers 30, 30 are provided in the installation portion 29 and extend along the extending direction of the rails 20, 20. It is rotatably supported on the platform 31 . That is, the first rod 28b is configured to move forward and backward while being supported by the support base 31 . Further, the support base 31 is formed with a groove 31a extending along the forward and backward movement direction of the first rod 28b at a position corresponding to the lower side of the long hole 28e in the first rod 28b.

As shown in FIGS. 3 and 8, a second air cylinder 32 is arranged at the rear portion of the truck 21 in an inverted posture. The second air cylinder 32 includes a second cylinder 32a disposed at the upper end of a mounting member 33 fixed to the carriage 21, and a second rod 32b that can protrude from the lower end of the second cylinder 32a. Prepare. Further, the mounting member 33 is provided with a guide hole 33a extending in the vertical direction and opened at the lower end. A pin 34 as a connecting member connected to the second rod 32b is slidably inserted in the guide hole 33a. supported by By urging the second air cylinder 32, the pin 34 is guided by the guide hole 33a to move up and down between the upper retracted position and the lower connected position. At the retracted position, the pin 34 is located above the elongated hole 28e of the first rod 28b of the first air cylinder 28, and disconnects the carriage 21 from the first air cylinder 28 (see FIG. 8 ( a)). Also, at the connection position, the pin 34 is configured to pass through the long hole 28e so that the lower end extends downward from the first rod 28b to connect the carriage 21 and the first air cylinder 28. (See FIG. 8(b)). Since the groove 31a of the support base 31 faces below the long hole 28e, the movement of the pin 34 to the connecting position is permitted. In the example, a second air cylinder 32 moving the pin 34 between the retracted position and the connected position provides connecting means connecting the carriage 21 to a first air cylinder (limiting device) 28 and the first air cylinder 32 .

Here, when the running motor 27 is stopped in order to position the carriage 21 running on the rails 20, 20 by driving the running motor 27 at the wire feeding portion S, the stop position of the carriage 21 is It may change in the front-rear direction. Therefore, in the first air cylinder 28, at the standby position where the first rod 28b is retracted most toward the first cylinder 28a side, the pin 34 remains in the long hole 28e even if the stop position of the carriage 21 changes. The length and position of the long hole 28e are set so that it can be inserted.

As shown in FIG. 2, the pit 19 is provided with a laser rangefinder 35 as a measuring means capable of measuring the movement distance of the truck 21 by irradiating the truck 21 with laser light and detecting the reflected light. is placed. The laser rangefinder 35 is arranged at a position capable of irradiating the carriage 21 of the supply stand 22 positioned at the wire feeding portion S with a laser beam, and winds the wire 12 around the winding drum 14 b of the winding device 15 . The moving distance of the carriage 21 in which the wire rod 12 is drawn out from the coil material 13 by the pulling force generated by the pulling is measured. As shown in FIG. 7, the control device 36 has a determination section 37, to which the winding motor 14a, the feeding motor 25 and the laser rangefinders 35, 35 are connected. The control device 36 constantly monitors whether or not the moving distance measured by the laser rangefinder 35 exceeds the threshold. , the wire rod feeding devices 10 and 11 (feeding motors 25 and 25) and the winding device 15 (winding motor 14a) are controlled to stop. The threshold value is set to a value shorter than the maximum stroke allowed for the first rod 28b in the first air cylinder 28, so as to prevent the first air cylinder 28 from being damaged due to movement of the carriage 21. It is designed to be preventable. When the control device 36 determines that there is an abnormality, the control device 36 may operate alarm means such as a buzzer or a lamp (not shown) to notify the operator of the abnormality.

[Action of Example]
Next, the operation of the wire rod feeding device of the embodiment constructed as described above will be described.

In the first wire rod feeding device 10, when the carriage 21 is moved by the traveling motor 27 to position the supply stand 22 at the first coil loading position S1, the coil material 13 is loaded onto the supply reel 24 at the first coil loading position S1. loaded. After the supply stand 22 of the second wire rod feeding device 11 is moved to the second coil loading position S2, the traveling motor 27 of the first wire rod feeding device 10 moves the carriage 21 to move the supply stand 22 to the wire rod feeding portion S. do. When the supply stand 22 is positioned at the wire feeding portion S, the pin 34 provided on the carriage 21 faces above the elongated hole 28e of the first rod 28b of the first air cylinder 28 (see FIG. 8(a)). ). By urging the second air cylinder 32 to lower the pin 34 from the retracted position to the connection position, the pin 34 passes through the long hole 28e, and the carriage 21 and the first air cylinder 28 are connected. They are connected (see FIG. 8(b)).

In the wire rod processing apparatus, the wire rod 12 pulled out from the coil material 13 of the supply stand 22 positioned in the wire rod feeding portion S is passed through the pinch roll 16, the straightening device 17, and the skin scraping device 18, and the end portion of the wire rod 12 is cut. It engages with the winding drum 14 b of the winding device 15 . By synchronously rotating the feeding motor 25 of the supply stand 22 and the winding motor 14 a of the winding device 15 , the wire 12 fed from the coil 13 of the supply stand 22 is straightened by the straightening device 17 . After being straightened and scraped by the scraping device 18, the strip is taken up by the take-up drum 14b of the take-up device 15.例文帳に追加

In the first wire feeding device 10, if the wire 12 of the coil 13 loaded on the supply reel 24 is locally bent or entangled, the wire 12 is not fed smoothly, and the feeding force of the wire 12 increases. . That is, the supply stand 22 is pulled toward the winding device by the drawing force of the wire 12, and the supply stand 22 moves forward in the wire drawing portion S. As shown in FIG. At this time, the pin 34 passing through the long hole 28e of the first rod 28b of the first air cylinder 28 contacts the front wall of the long hole 28e, thereby restricting the movement of the supply stand 22. be. Further, when the drawing force of the wire rod 12 becomes larger than the biasing force of the first air cylinder 28, the first rod 28b with which the pin 34 abuts moves together with the carriage 21 against the biasing force (Fig. 8(c)). reference). Then, when the increase in the feeding force of the wire rod 12 due to the local bending and entanglement of the wire rod 12 of the coil material 13 is eliminated, the supply stand 22 is moved to the wire rod feeding portion S by the biasing force of the first air cylinder 28. is pulled backwards at . That is, by allowing the carriage 21 to move so as to pull out the first rod 28b from the first cylinder 28a, fluctuations in the carry-out force acting on the carriage 21 can be absorbed. Further, even if the supply stand 22 moves forward at the wire feeding portion S, the supply stand 22 can be returned backward at the wire feeding portion S by the first air cylinder 28, and the supply stand 22 can be positioned at a fixed position. The wire rod 12 can be properly let out from the coil rod 13 at the bottom. Furthermore, when the carriage 21 moves due to a sudden increase in the drawing force of the wire rod 12, the load acting on the carriage 21 can be buffered by the biasing force of the first air cylinder 28, and the carriage 21 is inertially moved. can prevent large movements.

Here, the moving distance of the supply stand 22 (carriage 21) positioned at the wire feeding portion S is measured by the laser rangefinder 35 and constantly monitored by the control device 36. As shown in FIG. When the determination unit 37 determines that the moving distance measured by the laser rangefinder 35 has exceeded the threshold value, the control device 36 turns the feeding motor 25 of the supply stand 22 and the winding motor 14a of the winding device 15 on. Stop control. That is, the moving distance of the supply stand 22 is increased, and the pulling force of the winding device 15 can prevent the carriage 21 from moving further. Also, since the threshold value is set to a value shorter than the maximum stroke of the first rod 28b in the first air cylinder 28, it is possible to prevent the first air cylinder 28 from being damaged by movement of the carriage 21. can be done. Furthermore, it is possible to prevent the carriage 21 of the supply stand 22 from derailing and the supply stand 22 from overturning.

When the supply stand 22 of the first wire feeding device 10 and the supply stand 22 of the second wire feeding device 11 are exchanged, the second air cylinder 32 in the supply stand 22 of the first wire feeding device 10 is energized. , the pin 34 at the lowered position is raised to the retracted position, thereby disconnecting the wire rod feeding portion S from the first air cylinder 28 of the supply stand 22 . By driving the traveling motor 27 of the cart 21, the supply stand 22 is moved from the wire feeding section S to the first coil loading section S1, and then the traveling motor 27 of the second wire feeding device 11 moves the cart 21. to move the supply stand 22 from the second coil loading section S2 to the wire rod feeding section S. When the supply stand 22 is positioned at the wire feeding portion S, the second air cylinder 32 in the second wire feeding device 11 is energized to lower the pin 34 from the retracted position to the connection position in the same manner as described above. The pin 34 penetrates the long hole 28e of the first air cylinder 28, and the carriage 21 and the first air cylinder 28 are connected.

In the wire rod feeding apparatuses 10 and 11 of the embodiment, the first air cylinder 28 as a restricting device for restricting the movement of the supply stand 22 (truck 21) is moved from the coil material 13 supported by the supply stand 22 (truck 21). Since it is arranged on the lower side and the first air cylinder 28 does not face the delivery path of the wire 12 delivered from the coil 13, the delivery of the wire 12 is hindered by the first air cylinder 28. It is possible to perform smooth delivery without Also, even if the supply stand 22 (carriage 21) moves forward due to local bending or tangling of the wire rod 12, the supply stand 22 can move forward if the increase in the carrying force of the wire rod 12 surrounded by the local bending or entanglement is eliminated. The (carriage 21) can be pulled back to the original position by the biasing force of the first air cylinder 28. That is, by positioning the supply stand 22 (carriage 21) at the wire feeding portion S, the wire 12 can be fed out from the coil 13 appropriately.

In the wire rod feeding devices 10 and 11 of the embodiment, before the moving distance of the carriage 21 positioned at the wire rod feeding portion S exceeds the threshold value, the wire rod 12 is subjected to local bending, entanglement, or the like, and the wire rod 12 is subjected to the feeding force. When the increase is eliminated, the processing of the wire rod 12 can be continued without stopping the wire rod processing apparatus, so that the operation rate of the apparatus can be prevented from decreasing. When the moving distance of the cart 21 exceeds the threshold value, the wire rod processing apparatus can be stopped to avoid derailment of the cart 21 and overturning of the supply stand 22 . In addition, the laser rangefinder 35 for measuring the moving distance of the carriage 21 can accurately measure the moving distance of the carriage 21 even in an environment where dust or the like is generated. can be done. The laser range finder 35 has high durability, a long service life, and can reduce running costs.

The wire rod feeding devices 10 and 11 of the embodiment release the connection between the carriage 21 and the first air cylinder 28 simply by urging the second air cylinder 32 to move the pin 34 from the connection position to the retracted position. Therefore, the two supply stands 22, 22 can be easily exchanged with respect to the wire feeding section S. Further, the connection between the carriage 21 and the first air cylinder 28 is achieved simply by inserting the pin 34 into the elongated hole 28e of the first rod 28b, so that the configuration can be simplified. Further, since the pin 34 is passed through the long hole 28e to connect the truck 21 and the first air cylinder 28, even if the truck 21 is pulled by the pulling force of the wire rod 12 and the truck 21 tilts, , the pin 34 is difficult to come off from the long hole 28e, and the connection state between the carriage 21 and the first air cylinder 28 can be maintained. Furthermore, since the opening through which the pin 34 is inserted in the first rod 28b is the elongated hole 28e extending along the extending direction of the rails 20, 20, the carriage 21 is positioned at the wire rod feeding portion S by the traveling motor 27. , the pin 34 can be inserted through the elongated hole 28e and connected to the first air cylinder 28 without adjusting the position of the carriage 21, even if the position of .

Here, the initial relationship between the pin 34 and the elongated hole 28e of the first rod 28b when the carriage 21 is stopped so as to be positioned at the wire feeding portion S is as shown in FIG. 8(b). When the pin 34 is separated from the front wall of the elongated hole 28e in the rearward direction, the pin 34 comes into contact with the front wall due to an increase in the drawing force and moves further forward. The position where the pin 34 (carriage 21) is returned to the rear by the biasing force of the air cylinder 28 of 1 is the distance between the pin 34 in the initial relationship and the front wall of the long hole 28e from the position shown in FIG. 8(b). Forward. Thus, the position where the carriage 21 is stopped and the position where the carriage 21 is returned rearward by the biasing force of the first air cylinder 28 differ only by the distance, but the difference between the two positions is that the wire 12 is removed from the coil 13. The installation position of the first air cylinder 28, the length of the elongated hole 28e, and the like are set so as to be within the allowable range of fluctuation when drawing out.
