Technical field
The present invention relates to a kind of wire-cut electric discharge machining apparatus, this wire-cut electric discharge machining apparatus takes place to discharge and workpiece is processed at the machining gap that is formed between line electrode and workpiece, and this line electrode moves between a pair of line guiding piece.The present invention particularly relates to a kind of slotting exchange device of transfer matic that automatically line electrode is erected at the wire-cut electric discharge machining apparatus between a pair of line guiding piece.
Background technology
Wire-cut electric discharge machining apparatus with numerical control device has so-called transfer matic and inserts exchange device (AutomaticWireThreader); This transfer matic is inserted exchange device automatically makes line electrode insert the logical guiding piece of reaching the standard grade, beginning hole, the guiding piece that rolls off the production line successively, rolls seizure by batching.The beginning hole is for being formed at the hole about the 1mm in the workpiece before edm.Say that typically the diameter of line electrode is 0.20mm, the line guiding piece has φ 0.21mm inserting hole.
Fig. 7 representes to be called as the known high-precision line guiding piece of " circle mould ".Each line guiding piece is housed in the guiding piece assembly.Each guiding piece assembly has the spout nozzles of supplying with working fluid towards machining gap.Spout nozzles typically has the opening about φ 6mm.The line guiding piece is in than the opening of the spout nozzles position further from workpiece inevitably.
Generally speaking, the slotting exchange device of transfer matic has the jet nozzle that forms working fluid jet (to call " jet " in the following text) at the transport direction of line electrode coaxially.Jet constrained line electrode on one side is advanced to the guiding piece that rolls off the production line on one side.
Patent documentation 1 discloses jet nozzle by being arranged on the slotting exchange device of transfer matic in the guiding piece assembly with the coaxial mode of spout nozzles.Jet nozzle typically has the opening of φ 1.5mm.In order to utilize the line electrode channeling conduct of jet to the guiding piece that passed through to reach the standard grade, the opening of jet nozzle be configured in the guiding piece of reaching the standard grade under.Therefore, there is suitable distance in the opening from jet nozzle to the guiding piece that rolls off the production line.Therefore, jet constrained line electrode and the power that advances diminish, and in jet, are easy to generate turbulent flow.As a result, jet makes line electrode insert the probability step-down in the hole of leading to the guiding piece that rolls off the production line.
Particularly, only more difficult by jet guide line electrode in the occasion of using the line electrode that diameter is little, rigidity is extremely low.In addition, in the little occasion of diameter of beginning boring ratio jet, jet can not correctly guide to the front end of line electrode the occasion that begins the hole in the inlet disorder that begins the hole more.
In addition, long to the distance in beginning hole from jet nozzle can not make the occasion of upward guide piece assembly near the beginning hole because of the shape of workpiece, extremely difficult line electrode is inserted led in the beginning hole.

Yet, since the opening of jet nozzle have than spout nozzles little the diameter of Duoing, so, the jet nozzle that has prolonged to line electrode in the last angle that tilts between the guiding piece of rolling off the production line, be that cone angle has produced big restriction.
Patent documentation 3 and 4 discloses the transfer matic with the jet nozzle that can move up and down and has inserted exchange device.Insert when logical when carrying out transfer matic, insert logical success rate in order to improve line, make the opening of jet nozzle drop to spout nozzles opening near.When adding man-hour, the opening of jet nozzle rises under the guiding piece of reaching the standard grade, so that jet nozzle does not produce big restriction to cone angle.Yet, since the opening of jet nozzle have than spout nozzles little the diameter of Duoing, so jet nozzle has still limited cone angle.
Patent documentation 5 discloses the transfer matic with guiding tube that can move up and down that line electrode passes through and has inserted exchange device.Line electrode is inserted in the guiding tube, through supplying to the jet flow of guiding tube, line electrode is guided to the guiding piece that rolls off the production line.Typical guiding tube has the external diameter of 2mm and the internal diameter of 1mm.
Patent documentation 5 discloses the line guiding piece that can cut apart in order to pass guiding tube.Fig. 8 representes to be called as the line guiding piece that typically can cut apart of " composite die ".If the guiding piece of reaching the standard grade is a composite die, then can make guiding tube opening be positioned at the inlet in beginning hole.As a result, transfer matic is inserted logical success rate raising.
Yet, can think that the composite die durability is low, easy abrasion.In addition, can think that composite die is compared with the circle mould, position error is big.Can think that particularly composite die is than the circle mould, use in the processing of the last line electrode that tilts between the guiding piece of rolling off the production line, promptly precision is relatively poor in so-called " awl processing ".
Patent documentation 6,7 and 8 discloses the transfer matic with the jet nozzle that is called as " auxiliary jet " and has inserted exchange device.Auxiliary jet is limited to online inserting through the mode with the opening of sealing spout nozzles in the journey and is installed on the spout nozzles.Auxiliary jet can flatly be cut apart usually, so auxiliary jet can be dismantled from spout nozzles after online arc-spark stand was located at and rolls off the production line between the guiding piece.
Insert in the exchange device at such transfer matic, in the upward guide piece assembly, do not have the jet nozzle that limits cone angle.Because the opening part that can make auxiliary jet is in the position near the inlet that begins the hole, so line is inserted logical success rate height.Auxiliary jet is different with guiding tube, does not need composite die.And, even can not make the occasion of upward guide piece assembly because of the shape of workpiece, also can make the external diameter auxiliary jet easily approaching beginning hole littler than spout nozzles near the beginning hole.

As shown in Figure 3, mobile device 80 makes jet nozzle 20 swing on direction of rotation 1D with opening and closing device 70 between retreating position 10A and installation site 10B.Retreating position 10A that kind as shown in Figure 4 is the behind that transfer matic is inserted the main body 10 of exchange device 1.Installation site 10B that kind as shown in Figure 3 be spout nozzles 46 opening under.10B moves 1 stroke to jet nozzle 20 to the installation site from retreating position 10A, so line is inserted through the needed time shortening of journey.
Mobile device 80 has rocking bracket 81, drive unit 82, reaches linkage 83.Rocking bracket 81 is installed on the main body 10.Drive unit 82 is that fulcrum makes main unit 90 swing as putting around the X of level axle with the installation site 80X of rocking bracket 81, moves back and forth in direction of rotation 1D rotation.Linkage 83 is transformed into the straight reciprocating motion of drive unit 82 the rotation reciprocating motion back transmission of main unit 90.
The air source compressed and supplied air that the compressor that drive unit 82 is not represented from figure for utilization is such or the cylinder or the such cylinder assembly of hydraulic cylinder that move from the compressed oil that oil groove is supplied with.Drive unit 82 is taken in cylinder barrel at the groove position 10C of the behind of the main body 10 of being located at the slotting exchange device 1 of transfer matic shown in Figure 4 with the mode of vertical configuration.
When drive unit 82 drops to the lower position when the piston that makes cylinder assembly; Move towards the below with the first connecting rod 83V of the direct-connected linkage 83 of piston rod; One end utilizes the second connecting rod 83W of the linkage shown in Figure 3 83 that joint is connected with first connecting rod 83V; With pushing away on the main unit 90 that is bearing on the rocking bracket 81, jet nozzle 20 is swung towards retreating position 10A.When making piston rise to upper limit position, first connecting rod 83V moves toward the top, and second connecting rod 83W descends main unit 90, and jet nozzle 20 is swung to installation site 10B.
Be located at the occasion of behind that transfer matic is inserted the main body 10 of exchange device 1 at retreating position 10A with main unit 90; In the move mode of the combination of moving based on straight line; In order to make jet nozzle move to installation site 10B, need move it via a plurality of strokes from retreating position 10A.Mobile device 80 shown in Figure 4 constitutes with mode that can oscillating jet nozzle 20, so, can make jet nozzle 20 arrive installation site 10B by 1 stroke along the rotation motion track from retreating position 10A.Therefore, can not insert the logical needed time and cause important loss, can main unit 90 be housed in the position that does not hinder operation or processing transfer matic.
In following explanation, for ease, establishing the position that jet nozzle 20 is installed is the front side (front portion) of main unit 90, as the front end position of a pair of finger 61,62.In addition, along the central axis 90C through the position, rear end is made as the place ahead with the direction at front end position from the front end position of the main unit 90 that comprises opening and closing device shown in Figure 6 70.
In addition, will be made as vertically along the direction of the direction 1A quadrature of jet, will be made as laterally, will be made as the outside to the direction 1E that laterally leaves from central axis 90C with central axis 90C quadrature and with the direction of axis quadrature longitudinally with respect to central axis 90C.In addition; Will be parallel and be made as mounting plane with the face of axis quadrature longitudinally with central axis 90C; Below the face of will be parallel with mounting plane and being in the direction 1A of jet is called (back side), above the face that will be in the direction opposite with the direction 1A of jet is called (surface).
Insert in the opening and closing device 80 of attaching/detaching apparatus 7 of exchange device at the transfer matic of embodiment; Mobile device 80 makes main unit 90 swings; By 1 stroke jet nozzle 20 is configured in installation site 10A, so, for 10B is configured in spout nozzles 46 coaxially with jet nozzle 20 in the installation site; That kind as shown in Figure 3 is installed with respect to the mode of the mounting plane inclination of main unit 90 with jet nozzle 20.Therefore, though the axis longitudinally of main unit 90 is correctly not parallel with respect to the direction 1A of jet, the direction 1A of axis and jet regards as abreast and describes longitudinally.
First finger 61 and second finger 62 move towards mutually opposite direction in the direction with the amalgamation face quadrature of each amalgamation nozzle 91,92 of jet nozzle 20, promptly twoly open two modes of closing and open and close by so-called.Specifically, first finger 61 and second finger 62 are that the center moves back and forth around 1 mutually opposite direction rotation of court longitudinally of the direction 1A that is parallel to jet with same fulcrum 65.
At each position, rear end of first finger 61 and second finger 62; With from the front end position of the main unit 90 that comprises opening and closing device 70 the central axis 90C quadrature through the position, rear end and also with axis quadrature longitudinally laterally, form the semicircular otch 63,64 of head of opening at the direction 1E that leaves from central axis 90C.Therefore, the otch 64 of being located at the otch 63 of first finger 61 and being located at second finger 62 is at mutually opposite direction opening.Through otch 63,64 position, rear end of each finger 61,62 is formed hook-type.
Opening and closing device 70 makes first finger 61 and second finger 62 move and open and close towards mutually opposite direction in the direction with the amalgamation face quadrature of each amalgamation nozzle 91,92 of jet nozzle 20.10B opens and closes a pair of finger 61,62 to opening and closing device 70 in the installation site, the first amalgamation nozzle 91 is combined with the second amalgamation nozzle 92 or separates, makes the first amalgamation nozzle 91, the second amalgamation nozzle 92, and spout nozzles 46 combinations or separation simultaneously.
Specifically, opening and closing device 70 make first finger 61 and second finger 62 with same fulcrum 65 be the center around 1 longitudinally, as with the mounting plane of the direction of the amalgamation face quadrature of each amalgamation nozzle 91,92 on direction of rotation 1F move back and forth towards mutually opposite direction rotation and open and close.
Two pair structures of closing of opening that a pair of finger 61,62 in the attaching/detaching apparatus 7 opens and closes for the mutually opposite direction rotation of middle mind-set moves back and forth with same fulcrum 65; 10B makes the first amalgamation nozzle 91 combine with the second amalgamation nozzle 92 or separates in the installation site; Simultaneously, can make the first amalgamation nozzle 91, the second amalgamation nozzle 92, and spout nozzles 46 combine or separate.
Therefore, illustrated transfer matic is inserted exchange device 1 can be through 1 time action dismounting jet nozzle 20 and spout nozzles 46, can reduce the process number in the dismounting of jet nozzle 20, and shorten transfer matic and insert the logical needed time, be effective in this.In addition, the main points of the structure of Fig. 5 and main unit 90 shown in Figure 6 are: jet nozzle 20 is swung between retreating position 10A and installation site 10B.
Opening and closing device 70 comprises drive unit 78, arm 71,72 and conversion shaft coupling 73; This drive unit 78 is made up of the cylinder assembly that 1 direction of principal axis 90Y at the front and back straight line parallel with the central axis 90C of main unit 90 carries out straight reciprocating motion; This arm 71,72 is made up of a pair of arm, and this a pair of arm moves to mutually opposite direction rotation around the direction of rotation 1G of 1 direction of principal axis on mounting plane longitudinally with the mode that opens and closes a pair of finger 61,62 simultaneously; This conversion shaft coupling 73 is transformed into the straight reciprocating motion of 1 direction of principal axis 90Y of drive unit 78 the rotation reciprocating motion of the direction of rotation 1G of arm 71,72.
Drive unit 78 is the air actuated cylinder of air source compressed and supplied through from figure, not representing.The favourable part of cylinder is, with size compared, can make the direction of each amalgamation nozzle 91,92 mutual amalgamation of jet nozzle 20 apply necessary enough power at the pressure that overcomes water under high pressure.
Arm 71,72 specifically by from the front in the face of the time the right side the first arm 71 and from the front in the face of the time second arm 72 in left side constitute; This first arm 71 moves back and forth on the direction of rotation 1G opposite with direction of rotation 1F, being rotated around 1 direction of principal axis longitudinally on the mounting plane identical with the direction of rotation 1F of first finger 61, and first finger 61 is rotated at direction of rotation 1F; This second arm 72 moves back and forth on the direction of rotation 1G opposite with direction of rotation 1F, being rotated around 1 direction of principal axis longitudinally on the mounting plane identical with the direction of rotation 1F of second finger 62, and second finger 62 is rotated at direction of rotation 1F.
Each arm 71,72 has the cylinder element 74 of the roll form of the amalgamation that keeps jet nozzle 20 respectively.When arm 71,72 when direction of rotation 1G rotation is moved, the edge of the semicircular otch 63,64 of head that cylinder element 74 1 edges are respectively formed at the position, rear end of a pair of finger 61,62 moves around cylinder center's axle rotation on one side.The diameter of cylinder element 74 is littler than the diameter of the semi-circular arc part of otch 63,64.
As shown in Figure 5, when arm 71,72 near the direction of rotation 1G of central axis 90C rotation the time, be rotated and move while a part of side of cylinder element 74 contacts the edge that forms hook-type of otch 63,64.Therefore, because each arm 71,72 will pull to finger 61,62 rear of main unit 90 respectively, so each finger 61,62 is the center in opposite with the direction of rotation 1G direction of rotation 1F rotation of leaving from central axis 90C with fulcrum 65 and is drawn back.As a result, jet nozzle 20 is divided into the first amalgamation nozzle 91 and the second amalgamation nozzle 92.
On the other hand, as shown in Figure 6, when arm 71,72 during,, a part of side of cylinder element 74 moves while contacting the edge rotation of otch 63,64 in the direction of rotation 1G that leaves from central axis 90C rotation.Therefore; Because each arm 71,72 will push away the place ahead toward main unit 90 with each finger 61,62 respectively; So to be the center in the direction of rotation 1F rotation near central axis 90C opposite with direction of rotation 1G be urged each finger 61,62 closes with fulcrum 65.As a result, jet nozzle 20 amalgamations.
When a pair of finger 61,62 is urged when having closed, a part of side of cylinder element 74 stops with the edge of the straight line portion that is stuck in otch 63,64 and the mode of releasing to the place ahead of main unit 90.At this moment, the first arm 71 and second arm 72 just in time become to the place ahead of main unit 90 and stretch out arm and push up such state.
Because the mode that cylinder element 74 is released towards the place ahead with the edge of the straight line portion that is stuck in otch 63,64 stops; So; Only through being applied to the power that a pair of finger 61,62 is pushed back the straight line of the directive effect of opening; Cylinder element 74 does not move in the direction near central axis C, becomes the state of half locking.Be in the edge with respect to the straight line portion of otch 63,64 has extended such state by the right angle or near the angle at right angle occasion respectively at each arm 71,72; By the power living, that will expand jet nozzle 20 of cutting down output in the water under high pressure; Carrying out the direction transmission of the axis longitudinally of the substantially parallel arm 71,72 of 1 direction of principal axis 90Y of straight reciprocating motion with the cylinder assembly of drive unit 78; Be attached on the arm 71,72, a pair of finger 61,62 that will retreat with the supporting of two arms does not move it.
In the structure of illustrated opening and closing device 70; When having closed a pair of finger 61,62; Be applied on the piston pressing in the cylinder of the cylinder assembly of drive unit 78 so that conversion shaft coupling 73 is in the mode of the anterior position of main unit 90, the power that overcomes the water under high pressure that will make jet nozzle 20 separation is held the combination of jet nozzle 20 through compressed-air actuated trying hard to keep.
Therefore; The cylinder element 74 that is installed in the front end of arm 71,72 is revolted the power of the direction that each finger opens when jet nozzle 20 amalgamations; Actual landform becomes the state of locking, and cylinder assembly does not make jet nozzle 20 separate by the auxiliary confining force that keeps the combination of jet nozzle 20 of compressed-air actuated power.Therefore; The structure of Fig. 5 and supporting arm shown in Figure 6 60 and opening and closing device 70; Owing to can reduce the size of the proportional cylinder assembly of driving force and size cardinal principle, so, the size of the drive unit 78 of opening and closing device 70 can be reduced; Make main unit 90 compactnesses, and help preventing the separation of jet nozzle 20.
When jet nozzle 20 amalgamations, cylinder element 74 stops with the mode of forwards releasing at the edge of the straight line portion of otch 63,64, is the blocked state of direction that will open at a pair of finger 61,62; But because the structure that be cylinder element 74 rotate around cylinder center's axle, so, when conversion shaft coupling 73 rearward straight line move; Spur arm 71,72 and make it when rotating near the direction of central axis 90C; Cylinder element 74 rotations are moved, and deviate from the straight line portion of otch 63,64 simply, so; Cylinder assembly can easily make piston retreat, and can cut apart jet nozzle 20.
Say from principle; Certainly; In jet nozzle 20 amalgamations the time the stop position of cylinder element 74 surpass the rectangular position, edge with the straight line portion of otch 63,64 significantly, and arm 71,72 is in the too open occasion of the direction 1E that leaves from central axis 90C, when conversion shaft coupling 73 rearward moves; Arm 71,72 will can not rotate to the direction near central axis 90C at the direction 1E that leaves from central axis 90C to the direction rotation of leaving.Therefore, as Fig. 5 and shown in Figure 6, the stop position of the cylinder element 74 in the time of need having made jet nozzle 20 amalgamations is in arm 71,72 often to the position of returning near the direction of central axis 90C, but the design on have no problem.
One example of the action of the slotting exchange device of transfer matic is described with reference to Fig. 1~Fig. 6 below simply.
When carrying out automatic connecting, jet nozzle 20 that kind as shown in Figure 4 are in retreating position 10A.When jet nozzle 20 was in retreating position 10A, in order to prevent the damage of jet nozzle 20, a pair of finger 61,62 was closed.Yet,, a pair of finger 61,62 is opened in order to make the action that jet nozzle 20 is installed simpler.
According to input from the touch sensor on the screen of the button on the control panel in the numerical control device, switch or LCD, or according to the command signal of the NC program of having been deciphered, the not control device of expression starting among the figure.Control device is plugged in the sequencer of exchange device action for the order by regulation makes transfer matic.
At first, line electrode 2 is cut off in cutter 18 actions, makes the front end of line electrode 2 consistent.When line electrode 2 remains in the recovering mechanism 5, drive batching of discharger 56 and roll, residual line electrode 2 is discharged in the bucket 58.In addition, when having produced the cut off machine of line electrode 2, cut off machine is discharged to outside the machine with the front end processing device of not representing among the figure.
Then, make drive unit 82 actions of the mobile device 80 of attaching/detaching apparatus 7 according to signal, forwards push away main unit 90 from control device.That kind as shown in Figure 4 is closed and when being accommodated, between 90 shaking peroids, is made drive unit 78 actions of opening and closing device 70 in main unit when a pair of finger 61,62, opens a pair of finger 61,62, cuts apart jet nozzle 20.
As shown in Figure 3; The main unit 90 of the attaching/detaching apparatus 7 that has been depressed be bearing in fulcrum 81X be the center around X-direction with the pendulum shape on the rocking bracket 81 that direction of rotation 1D rotation is moved; So, swing to the installation site 10B under the opening that is in spout nozzles 46 once at direction of rotation 1D from retreating position 10A by 1 stroke.
In case jet nozzle 20 is in installation site 10B, that kind then as shown in Figure 6 makes drive unit 78 actions of the opening and closing device 70 in the main unit 90, and conversion shaft coupling 73 is advanced.If conversion shaft coupling 73 moves to the place ahead of main unit 90, then arm 71,72 is around axis is mobile to mutually opposite direction rotation at direction of rotation 1G towards the outside longitudinally.
Move while contact in the rotation of the edge of the otch 63,64 at the position, rear end that is formed at each finger 61,62 a part of side of cylinder element 74, to each finger 61,62 of the place ahead of main unit 90 release.Supported by fulcrum 65 by each finger 61,62 of forwards releasing; So; Being the center with fulcrum 65 moves being in direction of rotation 1F rotation on the mounting plane identical with the direction of rotation 1G of arm 71,72, opposite with direction of rotation 1G; Make amalgamation nozzle 91, the 92 mutual amalgamations of having installed in opposite directions, simultaneously, amalgamation nozzle 91,92 is combined with spout nozzles 46 with the front end position.
At this moment; Annular projection 48 with inclined plane is set on spout nozzles 46; At the top inner peripheral surface 24 of the housing 23 of each amalgamation nozzle 91,92 of the housing that constitutes jet nozzle 20, be formed on and annular projection 48 position in opposite directions with the cannelure 25 of annular projection 48 corresponding shape.Therefore; When 10A makes jet nozzle 20 amalgamations in the installation site; Cannelure 25 is chimeric along the inclined plane of annular projection 48, absorbs the offset of each amalgamation nozzle 91,92 and spout nozzles 46, does not unsuccessfully make each amalgamation nozzle 91,92 mutual amalgamation conscientiously; Simultaneously, each amalgamation nozzle 91,92 is combined in spout nozzles 46.
In addition; Jet nozzle 20 is at least on the top amalgamation face 23U of the housing 23 of each amalgamation nozzle 91,92, suitable with the position that forms chamber 22 housing upside, with in the mode chimeric each other with respect to the direction of the radially 1C quadrature of jet nozzle 20, incessantly mountain shaped protrusions 26 and be entrenched in the paddy shape groove 27 of the shape on the mountain shaped protrusions 26 is set in opposite directions.Therefore, when in the installation site during 10A amalgamation jet nozzle 20, paddy shape groove 27 is chimeric by the inclined plane guiding of mountain shaped protrusions 26, the amalgamation face amalgamation correctly of the first amalgamation nozzle 91 and the second amalgamation nozzle 92, and simultaneously, amalgamation face is sealed.
Like this; The transfer matic of embodiment is inserted exchange device and only just can jet nozzle 20 be installed on the spout nozzles 46 through 2 operations; These 2 operations swing to the operation of installation site 10B and 10B makes the first amalgamation nozzle 91 and the second amalgamation nozzle amalgamation jet nozzle 20 is installed in the operation of spout nozzles 46 in the installation site for make jet nozzle 20 with 1 stroke from retreating position 10A.In addition, the transfer matic of embodiment insert exchange device only the switching through a pair of finger 61,62 just can jet nozzle 20 be combined on the spout nozzles 46 and install.Therefore, the action of the slotting exchange device of the transfer matic of embodiment is fairly simple, and operation quantity is few.
After being installed in jet nozzle 20 on the spout nozzles 46, that kind as shown in Figure 2 supplies to jet nozzle 20 along the direction 1B that supplies with water under high pressure from spout nozzles 46 with water under high pressure.Supply to the water under high pressure of chamber 22, and spray coaxially in the direction that the direction 1A of jet sees line electrode 2 off from jet nozzle main body 21.
During this period, from jet feed unit 14 shown in Figure 1 jet is supplied to guiding tube 12.In addition, make upside energising body 32 shown in Figure 2 retreat into the position that does not hinder with the mode of leaving in the path of seeing off from line electrode 2.
Guiding tube 12 is descended; Up to the front end of guiding tube 12 cross upside energising body 32 arrive the guiding piece 31 of reaching the standard grade directly over height and position; And; Through dual-purpose is to see the tensioning of rolling off to roll 42 and do not break away from and see path ground off seeing off of seeing off of line electrode 2 rolled 16 co-operating, and the line electrodes 2 in the guiding tube 12 are seen off.
As shown in Figure 2, the direction 1B that the front end of the line electrode 2 of the guiding piece 31 that passed through by guiding tube 12 guiding to reach the standard grade, an edge are supplied with water under high pressure around, guiding, is sent to jet nozzle main body 21 by the water under high pressure of supplying with Yi Bian keep the seeing the path off of line electrode.Then, retraining by jet and to advance, be directed to the inlet in beginning hole.Insert and to lead to the beginning hole and the front end of the line electrode 2 of the guiding piece that passed through to roll off the production line, rolled by batching of discharger shown in Figure 1 56 and catch and wiring.
If obtain the signal that wiring has been accomplished, the then conveying of control device stop line electrode 2 by sensor.In addition, control device stops the supply of jet from jet feed unit 14 shown in Figure 1, and guiding tube 12 is risen, and arrives the initial position that is positioned at cutter 18 upsides up to the front end of guiding tube 12, and, stop the supply of water under high pressure from spout nozzles 46.
Then, as shown in Figure 5, make drive unit 78 actions of the opening and closing device 70 that is in main unit 90, make conversion shaft coupling 73 retreat into initial position.If conversion shaft coupling 73 moves to the rear of main unit 90, then each arm 71,72 moves to mutually opposite direction rotation at direction of rotation 1G towards the inboard near central axis 90C.At this moment, on one side a part of side of cylinder element 74 contacts the edge rotation that forms hook-type of the otch 63,64 at the position, rear end that is formed at each finger 61,62 respectively,, each finger 61,62 is pulled to the rear of main unit 90 Yi Bian move.
When each finger 61,62 is pulled to the rear; Each finger 61,62 with fulcrum 65 be the center, on the opposite direction of rotation 1F of the direction of rotation 1G that narrows to the inside near central axis 90C ground with arm 71,72; Move and open around 1 mutually opposite direction rotation of court longitudinally, each amalgamation nozzle 91,92 of the jet nozzle that is installed in the front end position in opposite directions 20 is cut apart.
Then, make the cylinder assembly action of the drive unit 82 of mobile device 80, with main unit 90 pull-up rearward.That kind as shown in Figure 3; The main unit 90 that has been pulled to the rear be bearing in fulcrum 81X be the center around X-direction by the pendulum shape on the rocking bracket 81 that direction of rotation 1D rotation is moved; So 10B swings to along direction of rotation 1D and is in the retreating position 10A of behind that transfer matic is inserted the main body 10 of exchange device 1 from the installation site with 1 stroke quickly.
Will be housed in the moment of the retreating position 10A of initial position making jet nozzle 20 pull down, make its swing from spout nozzles 46 separation, the wiring of line electrode 2 is accomplished, so line electrode 2 has been in the state that rolls off the production line between guiding piece that is erected at.At this moment; Jet nozzle 20 promptly, is vertically being cut apart from central authorities for two pair structures of closing of opening to the left and right with halving; A pair of finger 61,62 moves and opens and closes to mutually opposite direction; So each amalgamation nozzle 91,92 can not hang on the line electrode 2 that sets up and deviate from, thereby can leave from installation site 10B.
The line that the slotting exchange device of transfer matic of the present invention is not limited to illustrate is particularly inserted the structure of exchange device, as several examples of enumerating, can implement in the scope internal strain that does not break away from technological thought of the present invention.
