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 in 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, main unit 90 can be housed in the position that does not hinder operation or processing transfer matic.
In the following description, for convenience, 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 by 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 jet nozzle 20 being configured in spout nozzles 46 coaxially at installation site 10B, as shown in Figure 3, install 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.
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 by 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, be located at the otch 63 of first finger 61 and be located at the otch 64 of second finger 62 at mutually opposite direction opening.By 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.Opening and closing device 70 opens and closes a pair of finger 61,62 at installation site 10B, make the first amalgamation nozzle 91 and the second amalgamation nozzle 92 in conjunction with or separates, make simultaneously the first amalgamation nozzle 91, the second amalgamation nozzle 92, and spout nozzles 46 in conjunction with or separation.
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, installation site 10B make the first amalgamation nozzle 91 and the second amalgamation nozzle 92 in conjunction with or separate, simultaneously, can make the first amalgamation nozzle 91, the second amalgamation nozzle 92, and spout nozzles 46 in conjunction with or separate.
Therefore, illustrated transfer matic is inserted exchange device 1 can be by 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 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 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 simultaneously in the mode that opens and closes a pair of finger 61,62; 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.
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 rotates when mobile at direction of rotation 1G, 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 on one side around cylinder center's axle rotation.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,,, a part of side of cylinder element 74 moves while contacting the edge rotation of otch 63,64 when arm 71,72 during in the direction of rotation 1G that leaves from central axis 90C rotation.Therefore, because each arm 71,72 will push away each finger 61,62 the place ahead toward main unit 90 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 by 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 respectively with respect to the edge of the straight line portion of otch 63,64 by the right angle or the occasion of having extended such state near the angle at right angle 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 by 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, Fig. 5 and supporting arm 60 shown in Figure 6 and the structure of opening and closing device 70, owing to can reduce driving force and the size size of proportional cylinder assembly substantially, so, can reduce the size of the drive unit 78 of opening and closing device 70, make main unit 90 compactnesses, and help preventing the separation of jet nozzle 20.
When jet nozzle 20 amalgamations, cylinder element 74 is with at otch 63, the mode that the edge of 64 straight line portion is forwards released stops, for at a pair of finger 61, the blocked state of 62 directions that will open, but owing to be the structure of cylinder element 74 around cylinder center's axle rotation, so, when conversion shaft coupling 73 rearward straight line move, pulling arm 71,72 and make it the time near the rotation of the direction of central axis 90C, cylinder element 74 rotations are moved, deviate from otch 63 simply, 64 straight line portion, so cylinder assembly can easily make piston retreat, and can cut apart jet nozzle 20.
From the principle, certainly, in jet nozzle 20 amalgamations the time the stop position of cylinder element 74 surpass 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 is rearward mobile, 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, reach as shown in Figure 6 as Fig. 5, 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 has no problem in the design.
One example of the action of the slotting exchange device of transfer matic is described simply below with reference to Fig. 1～Fig. 6.
When carrying out automatic connecting, jet nozzle 20 is in retreating position 10A as shown in Figure 4.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 decoded NC program, the not control device of expression starting among the figure.Control device makes transfer matic plug in the sequencer of exchange device action for order in accordance with regulations.
At first, line electrode 2 is cut off in cutter 18 actions, makes the front end unanimity of line electrode 2.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.As shown in Figure 4, close and when being accommodated, between 90 shaking peroids, make drive unit 78 actions of opening and closing device 70, open a pair of finger 61,62, cut apart jet nozzle 20 in main unit when a pair of finger 61,62.
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 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, then as shown in Figure 6, make drive unit 78 actions of the opening and closing device 70 in the main unit 90, 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, releases each finger 61,62 to the place ahead of main unit 90.Each finger 61,62 of forwards being released is by fulcrum 65 supportings, 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 opposite to each other with the front end position, simultaneously, amalgamation nozzle 91,92 is combined with spout nozzles 46.
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 making jet nozzle 20 amalgamations at installation site 10A, cannelure 25 is chimeric along the inclined plane of annular projection 48, absorb the position skew of each amalgamation nozzle 91,92 and spout nozzles 46, unsuccessfully do not 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 mutually 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 at installation site 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 jet nozzle 20 can be installed on the spout nozzles 46 by 2 operations, these 2 operations swing to the operation of installation site 10B and make the first amalgamation nozzle 91 and the second amalgamation nozzle amalgamation jet nozzle 20 is installed in the operation of spout nozzles 46 at installation site 10B from retreating position 10A for make jet nozzle 20 with 1 stroke.In addition, the transfer matic of embodiment insert exchange device only the switching by a pair of finger 61,62 just jet nozzle 20 can 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, as shown in Figure 2, water under high pressure is supplied to jet nozzle 20 along the direction 1B that supplies with water under high pressure from spout nozzles 46.Supply to the water under high pressure of chamber 22, and spray coaxially in the direction that the direction 1A of jet sends line electrode 2 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 in the mode of leaving in the path of sending 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, by dual-purpose is to send the tensioning of rolling to roll 42 and do not break away from and send path ground sending of sending of line electrode 2 rolled 16 co-operating, and the line electrodes 2 in the guiding tube 12 are sent.
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 sending the path 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 finished, 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, around longitudinally 1 move and open towards the rotation of mutually opposite direction, each the amalgamation nozzle 91,92 that is installed in the jet nozzle 20 at front end position is opposite to each other cut apart.
Then, make the cylinder assembly action of the drive unit 82 of mobile device 80, with main unit 90 pull-up rearward.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, swing to along direction of rotation 1D from installation site 10B with 1 stroke quickly and to be in the retreating position 10A of behind that transfer matic is inserted the main body 10 of exchange device 1.
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 finished, 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 is two pair structures of closing of opening, promptly, vertically cutting apart to the left and right from central authorities 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.
