Description

  The present invention particularly relates to a supply device for an ultrafine wire material for separating ultrafine wires having a diameter of about 0.5 mm to 2 mm one by one for the processing and supplying the separated wires from one position to another position.

  Various devices have been proposed in the past for separating wires one by one for processing and processing and supplying them from one position to another. Most of them are wire rod feeding devices using a rotating rotor. . A wire rod feeding device using a rotating roller forms a stepped portion on the circumferential surface of the rotor along which the wire rod can be engaged along the longitudinal direction. When rotating the rotor, the wire rod is engaged with the stepped portion. The wire is rotated and fed.

  Therefore, according to this wire rod feeding device, if a step portion on the order of one wire rod is formed on the rotor, theoretically, the wire rods can be separated one by one and supplied from one side of the rotor to the other side. (For example, refer to Patent Document 1).

In addition, as a device that separates and supplies separate wires one by one, the wire gripping device equipped with a chuck consisting of a pair of claw portions is moved up and down, and the chuck claw portion is opened by the operation of the cylinder device when the chuck moves down. It is also known that the chuck is opened and pushed into a stocker section in which wire rods are accumulated, the chuck is closed, only one is gripped and lifted, and then moved to another position (for example, Patent Document 2). reference).
Japanese Patent No. 2942245 JP 2003-165615 A

  However, in the apparatus for feeding the wire by the rotation of the rotor described above, even if the stepped portion of the rotor is formed to a width that can engage only one wire, oil adheres to the surface of the accumulated wire. If this is the case, there is a disadvantage that the oil serves as an adhesive and is sent by the rotor in a state where, for example, two wires are attached. Accordingly, the reliability in that the wires are reliably separated and sent one by one is poor.

  Also, the above-mentioned gripping device having a chuck composed of a pair of claws is moved up and down, and when the chuck is moved downward, it is pushed into the stocker section where the wire is stored, and the chuck is opened, and the chuck is closed and only one is gripped. In a device that lifts and moves to another position, the wire mechanism can be surely picked up one by one by the gripping mechanism, but the structure of the structure is because the claw portion of the chuck needs to be opened and closed by the air cylinder device. Further, the opening and closing operation of the chuck is complicated, and the installation of the air cylinder device is expensive. There is a problem.

  Therefore, the present invention provides an improved structure of the supply device that solves the problems of the supply device for the ultrafine wire described above, and particularly focuses on the improvement of the chuck portion for gripping the wire in the latter described above. Without a special opening / closing device for opening and closing the chuck claw, the structure is simple, and the chuck claw is automatically pushed into the wire stock stored in the stocker, which is the wire stock storage. The wire can be securely gripped by the chuck, eliminating the need for a device for opening and closing the chuck, such as an air cylinder device, thereby reducing costs and ensuring only one wire. It is an object of the present invention to provide an apparatus for separating and supplying extra fine wire that can be separated and supplied.

In order to solve the above-mentioned problem, the invention according to claim 1 of the present invention is arranged such that a stocker portion for temporarily storing several extra fine wires and a vertically movable portion on one side of the upper portion of the stocker portion. A gripping device that grips one end of only one extra fine wire separated from among the several extra fine wires, and a reciprocation from one side of the stocker unit to the other side arranged between the stocker unit and the grasping device And a scooping member capable of scooping up the other end of the separated fine wire rod, which is movably disposed and gripped at one end by the gripping device, and is separated by the gripping device. After gripping one end of the extra fine wire, the rake member is moved from one side of the stocker unit to the other so that only one separated extra fine wire can be supplied for predetermined wire processing. Pole In the separation feed device of the wire, the gripping device comprises a chuck comprising a rotatable claw portion within a predetermined range of a pair provided on the downward, the pair of claw portions are opposed to each other with a slight gap to each other own weight each blade attachment holder of the gripping device to suspended pivotally mounting support, the openable to face the claw portion of the upper Symbol pair with each other in the distal end portion inside of the chuck in a predetermined restricted zone A tapered pinching portion is formed, and when the chuck is pushed into the wire rod in the stocker portion in which several extra fine wire rods are accumulated, the taper pinching portion at the tip of the pinch is pressed against the predetermined limit by the pushing force. Opening in the region, separating from the inside of the ultrafine wire accumulated in the stocker portion inside the tapered pinching portion, gripping and gripping only one ultrafine wire, and raising the chuck Location in, characterized in that a engageable baffle member ultrafine wire raised gripping by the gripping device.

  According to the first aspect of the present invention, in the separation and supply device for the ultrafine wire material, the gripping device includes a pair of chucks each including a pair of claw portions that are pivotable within a predetermined range. The claw portions of the chuck are opposed to each other to form a tapered pinching portion that can be opened and closed within a predetermined restriction area inside the tip end portion of the chuck, and the chuck serves as a wire material in a stocker portion in which several extra fine wires are accumulated. By pushing against the taper, the tapered pinching portion at the tip thereof opens within the predetermined restricted area, and is separated from the inside of the ultrafine wire accumulated in the stocker portion inside the tapered pinching portion. Since only one extra fine wire is sandwiched and gripped, the chuck can be pushed into the stock of the stocker part where the extra fine wire has accumulated, and the tapered pinch is limited to a predetermined limit. Open the Kana region, thereby entering into the innermost of the intruded wire into the pinching portion only one wire rod can be securely gripped. And since the baffle member that can be engaged with the ultrafine wire rod gripped by the gripping device is arranged at a position where the chuck is raised, the gripped ultrathin wire material hits the baffle member during the lift and from the gripping device. Since it isolate | separates, the said extra fine wire can be supplied on a scooping member.

  Therefore, a device for opening and closing the chuck such as an air cylinder device is unnecessary, and the cost can be reduced.

Further , the pair of claws of the chuck are rotatably supported and supported by the claw attachment holding parts of the gripping device so as to face each other with a slight gap and hang down under their own weight. By pushing in against the wire stock of the stocker part where the accumulator is accumulated, the pair of claws are rotated within the range allowed by the slight gap by the pushing force, and the chuck is moved within the predetermined limited area. Only one wire rod that opens and enters the innermost portion sandwiched between the tapered claw portions can be securely gripped. Therefore, a special device for opening and closing the chuck pawl is not required, and the cost can be reduced accordingly. Further, by removing the gripped wire, the chuck claw can be automatically suspended by its own weight and returned to the initial position.

  The upper pulley 11 and the lower pulley 12 over which each conveyor 1 is stretched are attached to rotating shafts 13 and 14 that extend in the width direction of the device A disposed at the upper and lower portions of the supply device A, respectively. The rotating shaft 13 is driven by a motor M1 through a transmission pulley 15 attached to the end of the shaft (see FIG. 4), whereby the conveyors 1 are mutually at the same speed through rotation of the shafts 13 and 14. 1 and 5 are rotated counterclockwise.

  On the outer periphery of the belt conveyor 1, a large number of receiving buckets 10 of wire rods W having a substantially L shape in a side view with the front in the rotational direction open are provided continuously along the outer peripheral surface of the belt of the conveyor 1. Several ultrafine wires w supplied for processing such as polishing and polishing are accommodated together in one inclined substantially L-shaped bucket 10, and the operation of accommodating the wire w in the bucket 10 is usually manual. Is made by When the substantially L-shaped bucket 10 on the outer peripheral surface of the belt conveyor 1 is reversed, several ultrafine wires w in the bucket 10 are automatically supplied onto the receiving portion 21 of the first guide portion 2. It is made so that.

  As described above, the first guide portion 2 includes the receiving portion 21 that receives the wire w sent from the belt conveyor 1 and the inclined portion 25 that follows the receiving portion 21, and the receiving portion 21 includes a cylinder device. A rotating shaft 23 that rotates via an arm portion 22 that swings when the end portion is pushed up by a push-up rod 20a, and a plurality of rotating plates 24 that are attached to the rotating shaft 23 at a predetermined interval are provided. In this embodiment, for convenience, five rotating plates 24 are attached to the rotating shaft 23, and the wire w supplied to the receiving portion 21, that is, supplied onto the rotating plate 24, is supplied to the rotating shaft 24. By forming the inclined surface that lowers the wire supply direction by rotating the plate 24 counterclockwise in the drawing, the plate 24 is sent from the rotating plate 24 onto the inclined portion 25 made up of a number of equally spaced plate-like members. It has been made so that it can.

  The inclined portion 25 that continues to the rotating plate 24 is lowered in front of the wire supply direction side, and the front of the inclined portion 25 forms a step portion with the second guide portion 4 that follows this, The step portion forms the accumulation portion 3 of the wire w. A rotating shaft 30 that is rotated by driving of the motor M2 is provided along the longitudinal direction of the collecting portion 3 of the wire w, and the rotating shaft 30 is provided with a number of wire feeding wheels 31 at equal intervals along the axis. The wire feed wheel 31 is provided with a plurality of feed claws 32 capable of feeding several wires w simultaneously at equal intervals on the rotation circumference.

  Then, several wire rods w accumulated in the wire rod accumulating portion 3 by the counterclockwise rotation of the wire rod feeding wheel 31 can be simultaneously sent to the second inclined guide portion 4.

  The second guide part 4 is composed of a number of equally spaced plate-like members, and the front part of the inclined part which is lowered in front of the wire supply direction side is formed as an extension part of the following guide part 4. A step portion is formed with the inclined guide portion 6, that is, a step portion composed of a concave portion is formed in each of the plurality of plate-like members, and the step portion is a wire rod w which is also a second wire accumulation portion. The stocker portion 5 is formed.

  The stocker unit 5 of the wire rod w is provided with a gripping device 50 that grips one side of the wire rod w on the upper side of the stocker unit 5 in the longitudinal direction. The wire rod gripping device 50 is connected to the one side of the stocker unit 5. The chuck 50b is formed as an elevating part of the cylinder device 50a fixed to the stay P1 protruding from the upper end of the column P. The chuck 50b is a plate located on the outermost side near the one side by the cylinder device 50a. The outside of the member can be moved up and down. Therefore, the tip of the chuck 50b can be moved downward from the lower part of the integrated wire w supported by the stepped portion, so that even if there is only one integrated wire w, it can be securely gripped. .

  As can be understood by referring to FIG. 6, a pair of claw portions 50c are attached downward to the chuck 50b, and the chuck 50b has a tapered inner pinch formed by the pair of claw portions 50c facing each other. 50d is provided. Each of the pair of claw portions 50c of the chuck 50b is rotatable to the claw attachment holding portion 50i via the shaft support portion 50g of the base portion 50h so that the base portions 50h can be opposed to each other with a slight gap D0. Installed.

For example, in a state where the claw portion 50c is suspended by its own weight with no acting force other than gravity applied, the gap 50 between the base portions 50h of about 0.5 mm is formed so as to face each other, and the pair of claw portions 50c The chuck 50b is attached to the claw mounting holding portion 50i so as to be rotatable without any biasing force such as a spring.

  Accordingly, the chuck 50b composed of the pair of claw portions 50c is chucked within a range allowed by the slight gap D0 between the base portions 50h of the claw portions 50c, that is, until the base portions 50h of both the claw portions 50c are in contact with each other. 50b can be opened.

  The tapered inner pinching portion 50d of the chuck 50b, which is composed of a pair of claw portions 50c that slightly opens and closes, is opposed to the stocker portion 5 of the wire material w, and the taper wide mouth portion 50e that faces the stocker portion 5 is followed by the tapered portion 50e. The entrance 50f of the loose gap D0 is provided, and the entrance 50f is, for example, about 0.9 mm in the free hanging state.

  Then, the chuck 50b pushed into the stocker unit 5 holds several wire rods w in the wide opening 50e of the inner pinching part 50d, so that the pinching part 50d is within the range allowed by the slight gap D0. And the chuck 50b is further pushed in, and the one of the several wire rods w held inside the tapered wide opening 50e of the pinching portion 50d slightly opened is inserted into the innermost side. Only the wire w1 is sandwiched near the entrance 50f of the sandwiching portion 50d and is gripped by the chuck 50b.

  As illustrated in FIG. 5, the space S between the chuck 50 b of the gripping device 50 that holds the wire rod w that moves up and down and the stocker unit 5 is refracted so that the front in the supply direction of the wire rod w is lowered. A scooping member 51 made of a square-shaped member having a portion 51 a is disposed so as to be able to reciprocate between both struts P on one side and the other side, and this reciprocating motion of the scooping member 51 is one in the longitudinal direction of the stocker portion 5. A wire gripping device that moves up and down along the rail 51b (see FIG. 3), which is fixed between the pillars P erected in the vicinity of the side and the vicinity of the other side and extends in the horizontal direction, and above the stocker unit 5 in the longitudinal direction. This is performed so as to pass below the lift position of the 50 chucks 50b.

  In order to reciprocate the scooping member 51 along the rail 51b, a chain 51c (see FIG. 3) driven in the horizontal direction by the motor M3 is stretched between the support pillars P. The member 51 is connected.

  The reciprocation between the one side in the longitudinal direction and the other side above the stocker portion 5 of the scooping member 51 is caused by the other side in which one wire w1 hanging down by only one of the one side is gripped by the chuck 50b of the gripping device 50. The wire rod w <b> 1 is placed on the third inclined guide portion 6 by shifting forward using the inclined portion 51 a of the scooping member 51 while lifting the wire upward. The moving end position of the scooping member 51 on the gripping device 50 side is set so as to be disengaged from the one end portion of the stocker unit 5.

  As can be understood from FIGS. 3 and 5, the wire w1 gripped by the chuck 50b of the gripping device 50 is dropped in the vicinity of the wire gripping device 50 via a support arm (not shown) extending from one column P. A dropping rod (baffle member) 52 is provided, and the dropping rod 52 is at a position perpendicular to the longitudinal direction of the wire w1 gripped by the chuck 50b and at a position in the middle of the chuck 50b rising (see FIG. 5). Reference) is configured to be positioned.

  Then, the other half of the hanging portion of the wire w1 that is gripped and lifted by the chuck 50b of the wire gripping device 50 is synchronized with the timing at which the majority is placed on the third inclined guide portion 6 by the movement of the scooping member 51. Then, the tip 52a of the drop bar 52 is held by the chuck 50b and engages with the upper part of the wire w1 that rises, so that the wire w1 is separated from the chuck 50b by the drop bar 52 (also in FIG. 7). reference).

  The lower portion in the supply direction of the guide portion 6 that is the third inclined portion forms the position adjusting portion 7 of the wire rod w where the one dropped wire rod w1 is stationary, and the position adjusting portion 7 of the wire rod w1 A cylinder device 70 is disposed at the bottom near the both ends (see FIG. 3), and a cross beam 71 (see FIGS. 2, 3, and 5) is attached across the upper end of the push-up rod 70a of these cylinder devices 70. A large number of wire pushing members 72 having upper end portions 72 a formed as inclined surfaces 72 b at equal intervals along the longitudinal direction of the cross beam 71 are provided on the upper portion of the beam 71.

  Accordingly, the wire rod w1 is simultaneously pushed up at a plurality of locations in the longitudinal direction through the wire rod push-up member 72 provided on the cross beam 71 by the simultaneous raising of the push-up rods 70a of the two cylinder devices 70, and the upper end portion 72a of the push-up member 72 is lifted. It is brought close to the lower side of the inclined surface 72b and is lifted while contacting the front wall of the position adjusting portion 7 so as to be placed on the inclined portion of the fourth guide portion 8 made up of a number of equally spaced plate-like members. Has been made.

  A transport device 9 composed of a large number of transport rollers 90 arranged in series is disposed in a lower portion in front of the supply direction of the fourth guide portion 8, and is supplied via an inclined portion of the fourth guide portion 8. Further, the single wire rod w1 is placed on the conveyance roller 90 of the conveyance device 9 so as to be supplied to a processing device (not shown) for performing predetermined processing such as cleaning and polishing.

  The separating and supplying apparatus A for the wire rod w in the present embodiment is as described above.

  Here, the operation of the wire separating and supplying apparatus A in the present embodiment will be described.

  First, several ultrafine wires w are placed and accommodated in the bucket 10 of the belt conveyor 1. The supply operation of the wire rod w into the bucket 10 is usually performed manually while observing the state of the entire flow of the wire rod w in the supply device A with respect to the belt conveyor 1 in a driving state.

  Several wire rods w sent above the conveyor 1 by the belt conveyor 1 to be driven are turned on the receiving portion 21 of the first guide portion 2 from the bucket 10 by the reversal of the bucket 10 due to the direction change of the conveyor belt 1. When the release of the wire w onto the receiving portion 21 is detected, the push-up rod 20a of the cylinder device 20 rises and the rotation shaft 23 rotates through the swinging of the arm portion 22 to rotate. The wire w is fed onto the inclined portion 25 in front of the supply side by the swinging of the rotating plate 24 accompanying the rotation of the shaft 23.

  Several wires w rolling or sliding down on the inclined portion 25 are accumulated in the collecting portion 3 of the wire w in front of the inclined portion 25, and the accumulation of the wire w on the wire collecting portion 3 is detected by the detecting device S1 (see FIG. 2). Is detected, the wire feed wheel 31 provided with the feed claw 32 rotates, and several wires w are simultaneously fed onto the inclined portion of the second guide portion 4 by the rotation of the wheel 31 and roll on the inclined portion. Several wire rods w that move or slide are accumulated in the stocker section 5 in the front of the supply direction.

  When the wire w accumulates in the stocker unit 5, the state is detected by the detection device S <b> 2, and the wire gripping device 50 arranged on one side of the stocker unit 5 is activated, and several wires w accumulated in the stocker unit 5 are actuated. On the one side, most of the gripping device 50 is caught in the wide opening 50e of the chuck 50b by being pushed into the stocker portion 5 by the lowering of the chuck 50b of the gripping device 50, but slightly opened by further pushing of the chuck 50b. Only one side of one wire rod w1 that has entered the innermost portion of the one side of the wire rod w that enters the gap D1 between the pair of claw portions 50c that narrows above the chuck 50b is gripped (see FIG. 6). .

  That is, as can be understood by referring to FIG. 6, the pair of claws 50c of the chuck 50b are suspended by the base 50h forming a predetermined gap D0 under the action of gravity. It is pushed into the stocker unit 5 and several wire rods w are held by the wide mouth portion 50e of the inner pinching portion 50d, and the pair of claw portions 50c are pushed by the slight gap D0 of the base portion 50h by further pushing of the chuck 50b. Within the permissible range, they open outward (see the phantom line), whereby the wire w caught by the wide opening 50e of the chuck 50b moves upward along the slightly opened gap D1 of the tapered pinching portion 50d. The wire w1 that has entered the entrance portion 50f of the slight gap D0, which is a gentle taper portion that has become narrower at the farthest side, enters the deeper portion from the lower side by another wire w. Sandwiched between headed pushed in both the claw portion 50c towards will consequently be pressed against the grip on the tapered upper part between Ryotsume portion 50c.

  The chuck 50 b of the gripping device 50 that grips one side of the single wire rod w <b> 1 is raised by the operation of the cylinder device 50. One wire w1 that has been gripped and lifted by the raising of the chuck 50b hangs down on the other side of the gripping portion, but when the raising of the chuck 50b reaches a predetermined position, that is, the moving position of the scooping member 51 is changed. When the height is exceeded, the switch (not shown) of the driving motor M3 of the scooping member 51 is turned on, and the scooping member 51 starts to move. As the scooping member 51 moves from one side of the stocker portion 5 to the other side, the hanging portion of the wire rod w is sequentially lifted and sequentially moves forward along the inclined portion 51a of the scooping member 51.

  When the majority of the hanging portion of the wire rod w1 moves forward due to the rise of the chuck 50b and the movement of the scooping member 51, the wire rod w gripped on one side by the chuck 50b engages with the dropping rod 52 during the ascent. Thus, one side of the wire rod w1 that has been separated from the chuck 50b (see FIG. 7) falls onto the inclined portion of the third guide portion 6.

  Therefore, since the other side of the wire w1 rests on the inclined portion 51a of the scooping member 51 and one side rests on the inclined portion of the third guide portion 6, it rolls or slides down on these inclined portions and moves forward on the supply side. It moves and stops at the position adjustment portion 7 that is lowered in front of the inclined portion of the third guide portion 6.

  When the wire rod w1 is stopped at the position adjusting unit 7, the detecting device S3 detects it, and immediately, the push-up rods 70a of the cylinder devices 70 at the left and right ends of the position adjusting unit 7 are simultaneously lifted and attached across the upper end of the push-up rod 70a. A number of push-up members 72 on the horizontal beam 71 are pushed up, and the wire rod w1 is pushed up by the inclined surface 72b of the push-up member 72 so that the wire rod w1 is brought close to the wall portion in front of the position adjusting unit 7 so that the wire rod w1 The wire w1 is placed on the inclined portion of the fourth guide portion 8 while correcting the position straight.

  The wire w1 placed on the inclined portion of the fourth guide portion 8 rolls or slides down on the inclined portion and is placed on the transfer roller 90 of the transport device 9, and this state is detected by the ground detection device S4. Thus, the transport device 9 is driven, and one wire rod w1 is supplied to a predetermined wire rod processing device (not shown).

  Since the wire separating / supplying apparatus A according to the present embodiment has the above-described structure, the following effects can be obtained.

  The pair of claws 50c of the chuck 50b of the gripping device 50 is provided with a tapered pinching portion 50d and hangs down with a predetermined slight gap D0 under the action of gravity in its free state under its own weight. The chuck 50b can be opened and closed within a range allowed by the slight gap D0, and is automatically opened by the pushing force when pushed into the wire rod w in the stocker unit 5, so that the tapered pinching portion 50d Only one wire rod w1 that has entered the innermost part can be reliably gripped. Therefore, a conventionally used cylinder device or the like for opening and closing the claw portion 50c of the chuck 50b becomes unnecessary.

  One wire w1 gripped by the tapered pinching portion 50d and lifted on one side thereof is lifted by a scoop member 51 whose other side hangs down along the wire w1 and placed on the inclined portion 51a. Simultaneously with pushing forward, the grip on the one side is removed by the drop bar 52, so that one wire w1 is surely sent to the next wire feeding step.

  In this manner, the wire w can be picked up and separated only by the vertical movement of the chuck 50b and the dropping bar 52, and a special opening / closing mechanism (cylinder device), a motor, a sensor and the like for driving the chuck 50b are provided. Since it is not necessary, the structure is simple and the cost can be kept low.
