Description

  The present invention relates to a supply device that supplies metal wires one by one to a predetermined position.

  2. Description of the Related Art When supplying metal wires with chamfering, flaw detection, correction, or the like, a supply device is known that supplies metal wires to a machine one by one from a large number of metal wires accumulated in advance. When supplying a metal wire with such a supply device, the small-diameter metal wire has low rigidity, so if it is supplied by a conventional metal wire supply device, the wire is likely to be bent in the middle and cross with other wires. For this reason, good feeding could not be performed.

  In order to solve such a problem, in Patent Document 1, a first feed rotor in which rake blades are radially formed in the vicinity of the upper end portion of the inclined portion is disposed, and a rake groove is formed in an intermediate portion of the inclined portion. An invention is disclosed in which the second feed rotor is arranged in parallel with the first feed rotor. According to such an invention, the metal wire can be fed stepwise by the first feed rotor and the second feed rotor, so that even a small-diameter metal wire can be supplied efficiently and reliably.

Japanese Utility Model Publication No. 7-942

However, in the structure described in Patent Document 1 described above, the depth of the rake groove of the second feed rotor needs to be formed to a depth suitable for scooping up one or two metal wires. For this reason, there existed a problem that the thickness of the metal wire which can be handled with a supply apparatus will be restricted.
Then, this invention makes it a subject to provide the supply apparatus of the metal wire which can handle the metal wire of various thickness.

  The present invention has been made to solve the above-described problems, and is characterized by the following.

  The invention according to claim 1 includes an inclined portion in which the metal wire is carried, and a plurality of feed rotors arranged so as to protrude from the inclined portion. A rake portion for scooping up the metal wire is sometimes formed, and the rake portion of the feed rotor arranged on the upstream side of the inclined portion is deeper than the rake portion of the feed rotor arranged on the downstream side of the inclined portion. And at least one of the plurality of feed rotors is movable in a direction to be buried with respect to the inclined portion.

  In addition to the features of the invention described in claim 1, the invention described in claim 2 is a drive device, a drive pulley connected to the drive device, a driven pulley connected to the feed rotor, A belt wound around the drive pulley and the driven pulley, and a belt guide provided so as to face the drive pulley across the belt, and the belt guide has the feeding rotor at the inclined portion. On the other hand, when the belt moves in the direction of burying, the belt is loosely supported so as not to be detached from the drive pulley.

  The invention according to claim 1 is as described above, and the rake portion of the feed rotor disposed upstream of the inclined portion is deeper than the rake portion of the feed rotor disposed downstream of the inclined portion. Since it is formed, the metal wire can be divided and sent in stages by a plurality of feed rotors. According to such a structure, even a small-diameter metal wire with low rigidity can be supplied efficiently and reliably.

  In addition, since at least one of the plurality of feed rotors can move in the direction of burying with respect to the inclined portion, the feed rotor to be used can be changed in accordance with the thickness of the metal wire. For example, if the feed rotor arranged on the downstream side is moved in a direction to be buried in the inclined portion, even a relatively large diameter metal wire that cannot be scooped up by the feed rotor arranged on the downstream side. Can be handled by the same feeding device.

  The invention according to claim 2 is as described above, and is a belt that supports the belt with loose tension so that it does not come off the drive pulley when the feed rotor moves in a direction to be buried in the inclined portion. Since the guide is provided, the belt does not come off the drive pulley even when the feed rotor is moved up and down. Therefore, even when the feed rotor is repeatedly moved up and down, it is possible to make it difficult to cause a malfunction due to a poor meshing between the belt and the drive pulley.

FIG.

  Embodiments of the present invention will be described with reference to the drawings.

  The apparatus for supplying metal wire W according to the present embodiment is for supplying the metal wire W one by one to a chamfering machine, for example, as shown in FIG. 1 and FIG. An accumulation unit 11 and a separation supply unit 20 are provided.

  The stacking unit 11 is for stacking a large amount of metal wire W. The stacking portion 11 is configured by connecting a horizontal portion 11a and a vertical portion 11b in an L shape, and is supported rotatably with respect to the base 10 by a support shaft 12 provided at the tip of the horizontal portion 11a. Has been. A stacking unit cylinder device 13 is disposed below the stacking unit 11, and the stacking unit 11 tilts when the stacking unit cylinder device 13 operates. Specifically, when it is desired to accumulate the metal wire W on the accumulation portion 11, the accumulation portion 11 is inclined slightly rearward, and the metal wire W is accumulated in the valley formed by the horizontal portion 11a and the vertical portion 11b. . On the other hand, when the metal wire W is sent in the direction of the separation supply unit 20, the stacking unit 11 is tilted forward in the direction of the separation supply unit 20, and the metal wire W is rolled over the horizontal part 11 a to Send in the direction.

  Note that the method of sending the metal wire W from the stacking unit 11 to the separation supply unit 20 is not limited to the above-described configuration. For example, the metal wire W may be sequentially moved to the separation supply unit 20 by a plurality of hooks on which a large number of metal wire W can be placed.

  The separation supply unit 20 includes an inclined part 21 to which the metal wire W is conveyed, a plurality of rows of feed rotors 22 and 27 arranged so as to protrude from the inclined part 21, and a feed for moving the feed rotor 27. And a rotor cylinder device 33.

  The inclined portion 21 is connected to the horizontal portion 11a of the accumulation portion 11, and is inclined so that the side connected to the accumulation portion 11 becomes higher in order to roll the metal wire W sent from the accumulation portion 11. . As shown in FIG. 1, the inclined portion 21 is configured by arranging a plurality of parallel plate-like materials at predetermined intervals.

  The feed rotors 22 and 27 are for adjusting the number of metal wires W rolling on the upper surface of the inclined portion 21 in a stepwise manner. In the present embodiment, the feed rotors 22 and 27 are formed between the first feed rotor 22 and the second feed rotor 27. Two feed rotors 22 and 27 are provided. The rotation shafts of the feed rotors 22 and 27 are provided so as to be orthogonal to the feed direction of the metal wire W.

  These feed rotors 22 and 27 are formed by forming a plurality of scoop portions 22b and 27b on the outer peripheral surfaces of the cylindrical portions 22a and 27a. The scooping portions 22b and 27b are for scooping up the metal wire W on the inclined portion 21. The shape of the scooping portions 22b and 27b may be any shape that can scoop the metal wire W when the feed rotors 22 and 27 are rotated. For example, the scooping portions 22b and 27b have a wing shape (protruding shape) as shown in FIG. There may be a groove shape.

  As shown in FIG. 1, these feed rotors 22 and 27 are configured by arranging a plurality of cylindrical portions 22a and 27a coaxially, and are formed between the plurality of cylindrical portions 22a and 27a. In the gap G, the inclined portion 21 described above and a transition plate 34 described later are disposed.

  As shown in FIG. 2, drive devices 23 and 28 (for example, electric motors) are operatively connected to the feed rotors 22 and 27, respectively, and their operation timing, speed and the like are controlled by a control device (not shown). Has been. When the driving devices 23 and 28 are operated, the driving pulleys 24 and 29 connected to the driving devices 23 and 28 rotate. When the drive pulleys 24 and 29 are rotated, the driven pulleys 25 and 30 connected to the feed rotors 22 and 27 are rotated in conjunction therewith. That is, belts 26 and 31 are wound around the driving pulleys 24 and 29 and the driven pulleys 25 and 30, and the driving force of the driving devices 23 and 28 is sent to the feed rotors 22 and 27 via the belts 26 and 31. Communicated. As a result, the feed rotors 22 and 27 rotate to scoop the metal wire W and supply it downstream.

  By the way, the first feed rotor 22 is arranged on the upstream side of the inclined portion 21 with respect to the second feed rotor 27. Further, the rake portion 22 b of the first feed rotor 22 is formed to be deeper than the rake portion 27 b of the second feed rotor 27. With such a configuration, the metal wire W on the inclined portion 21 is sent in stages by the plurality of feed rotors 22 and 27.

  That is, first, a large amount of the metal wire W is accumulated in the accumulation unit 11. Then, the horizontal portion 11 a of the stacking portion 11 is slightly tilted forward by operating the stacking portion cylinder device 13, and a part of the metal wire W is dropped onto the tilted portion 21. The metal wire W that has dropped onto the inclined portion 21 hits the first feed rotor 22 and stops. Then, when the first feed rotor 22 is rotated, several metal wires W are scooped by the scooping portion 22 b and moved forward, and the inclined portion 21 is rolled to stop before the second feed rotor 27. . When the second feed rotor 27 rotates, a smaller number of metal wires W than the number of the first feed rotor 22 scooped are scooped by the scooping portion 27b and moved forward in the rotation.

  The feed rotor cylinder device 33 is for moving the second feed rotor 27 in a direction to be buried in the inclined portion 21. The feed rotor cylinder device 33 is an actuator for vertically moving the pedestal portion 36 that pivotally supports the second feed rotor 27, and slides inside the base 33 a and a base 33 a fixed to the base 10. A piston rod 33b. A pedestal 36 is fixed to the tip of the piston rod 33b.

  When the feed rotor cylinder device 33 is operated, the second feed rotor 27 moves up and down, and the second feed rotor 27 protrudes from the inclined portion 21 as shown in FIG. As shown in FIG. 4B, it is possible to switch between the state in which the second feed rotor 27 is buried in the inclined portion 21. The mechanism for moving the second feed rotor 27 up and down is not limited to the cylinder device as described above, and may be another mechanism, for example, a mechanism for manually moving the second feed rotor 27 up and down. .

  In this way, by moving the second feed rotor 27 up and down, it is possible to switch whether or not the second feed rotor 27 is used. For example, when a metal wire W having a relatively small diameter is fed, if the feeding device is operated using the second feed rotor 27, even the metal wire W having a small diameter with low rigidity can be reliably fed. Can do. When the metal wire W having a relatively large diameter is fed, if the feeding device is operated without using the second feed rotor 27, the second feed rotor 27 cannot be scooped up. It can also correspond to a metal wire W having a diameter.

  By the way, in this embodiment, when the 2nd feed rotor 27 exists in the state which protruded with respect to the inclination part 21, as shown to Fig.4 (a) etc., the rotating shaft of the 2nd feed rotor 27 is an inclination part. Therefore, a slit (not shown) through which the shaft of the second feed rotor 27 passes is opened on the upper surface of the inclined portion 21. Therefore, when the metal wire W rolls on the inclined portion 21 with the second feed rotor 27 buried in the inclined portion 21, the metal wire W may fall into the slit of the inclined portion 21. is there. Thus, when there exists a possibility that the metal wire W may fall to the slit of the inclination part 21, the fall of the metal wire W can be prevented by providing the transition board 34 as shown in FIG. The crossover plate 34 is for closing the slit of the inclined portion 21. In this embodiment, the metal wire W is placed on the crossover plate 34 by rotating around the rotary shaft 35 to close the slit. Can be rolled, so that the metal wire W does not fall into the slit.

  As described above, the feed rotors 22 and 27 according to the present embodiment receive the driving force of the driving devices 23 and 28 via the belts 26 and 31 and rotate. For this reason, if the second feed rotor 27 is buried (lowered) in the inclined portion 21, the tension of the belt 31 may be loosened, and the belt 31 may be detached from the drive pulley 29. If the belt 31 is disengaged from the driving pulley 29, even if the second feed rotor 27 is moved up next and the tension of the belt 31 is restored, the meshing between the belt 31 and the driving pulley 29 is not stable, resulting in malfunction. There is a risk of becoming. In the present embodiment, in order to avoid such a problem, the belt guide 32 is provided so as to face the drive pulley 29 with the belt 31 interposed therebetween.

  As shown in FIG. 2, the belt guide 32 is a substantially U-shaped member provided so as to cover the lower half circumference of the drive pulley 29, and the second feed rotor 27 is embedded in the inclined portion 21. The belt 31 that is loose in tension is supported so that it does not come off the drive pulley 29 when it moves. By providing such a belt guide 32, the belt 31 does not come off the drive pulley 29 even when the second feed rotor 27 is moved up and down. Therefore, even when the vertical movement of the second feed rotor 27 is repeated, it is possible to make it difficult for malfunctions caused by the inadequate meshing between the belt 31 and the drive pulley 29 to occur.

  As described above, according to the present embodiment, the rake portion 22 b of the first feed rotor 22 disposed on the upstream side of the inclined portion 21 is not connected to the second feed rotor 27 disposed on the downstream side of the inclined portion 21. Since the metal wire W is formed so as to be deeper than the rake portion 27b, the metal wire W can be divided and fed in stages by the plurality of feed rotors 22 and 27. According to such a structure, even a small-diameter metal wire W with low rigidity can be supplied efficiently and reliably.

  Moreover, since at least one of the plurality of feed rotors 22 and 27 is movable in the direction of burying with respect to the inclined portion 21, the feed rotors 22 and 27 used in accordance with the thickness of the metal wire W 27 can be changed. For example, if the second feed rotor 27 disposed on the downstream side is moved in a direction to be buried in the inclined portion 21, the second feed rotor 27 disposed on the downstream side cannot be scooped up. Even the metal wire W can be handled by the same supply device.

  In the above description, the second feed rotor 27 is configured to be movable up and down, but the present invention is not limited thereto, and the first feed rotor 22 may be configured to be movable up and down. In the above description, the number of feed rotors 22 and 27 is two. However, the number is not limited to this, and the number of feed rotors may be three or more. For example, a large number of feed rotors having different rake portion depths may be arranged and used in appropriate combinations so that the wire rods can be adapted to metal wires W of various diameters. For example, if three feed rotors are provided and all the feed rotors are movable up and down, eight combinations (2 to the power of 3) are possible. Thus, the feed rotor to be used may be finely changed depending on the type of the metal wire W to be handled.

  Although not specifically described above, a pressing member or kicker as described in Patent Document 1 (Japanese Utility Model Publication No. 7-942) may be provided on the downstream side of the feed rotors 22 and 27.
