Description
The application is to be May 22 nineteen ninety-five the applying date, and application number is 03122075.4, and denomination of invention is divided an application for the patent application of " Strip processing device ".
Technical field
The present invention relates to the Strip processing device of steel plate etc., for example electroplanting device, purification device etc., particularly in liquid bath, the homopolarity electrode of subtend configuration male or female etc., the Strip processing device that band is passed through between these electrodes.
Background technology
In above-mentioned Strip processing device, in order to increase output or to boost productivity, generally be wish to shorten interelectrode interval such as band and male or female or the treatment solutions such as electroplate liquid between the electrode of band and male or female etc. are stirred and supply with ion between the electrode of band and male or female etc.Therefore, the applicant has developed a kind of device, that is at the identical electrodes inner face of subtend configuration, subtend ground or dispose isolator (stabilizer) alternately, on these isolators, be provided with working direction, from the oblique a kind of device of the conical surface (spy opens flat 3-20494) of electrode side direction band inclination along band.In this way, the interelectrode gap of homopolarity can be made minimumly, improve the productivity of above-mentioned band device.
, also there are some problems, need be improved for above-mentioned Strip processing device.
The 1st problem relates to regulate the electrode mechanism at interval each other.For above-mentioned Strip processing device, because interpolar is narrow, if electrode is made when fixed, the rope of initial stage during logical plate can not pass through.Perhaps, in exploitation originally, when the portion that is connected of band because during thickenings such as welding, this part contacts with stabilizer can cause the stabilizer breakage.Therefore, owing to these reasons, be necessary to be provided with the on-off mechanism of electrode.
In the past, the space of rope when leading to plate in order to ensure the initial stage, and make the weld part of band in current, not collide, and being provided with as shown in figure 13, the electrode that makes each both sides is at the openable on-off mechanism of opposite side and its operating portion.
Among Figure 13, in vertical bath type liquid bath 1, the treatment solutions of not representing in the load map such as electroplate liquid.Electrode 2 can use male or female, and perhaps anode and negative electrode can permutable electrodes.And the upside of electrode 2 uses lateral electrode carriage 3 support, is provided with the air cylinder 4 that the side switch of electrode is used on this upside electrode bracket 3.And support with downside electrode bracket 5 that at the downside of each electrode 2 be provided with the cam 6 that side switch is used on this downside electrode 5, interelectrode switch motion is carried out in action in the time of by a pair of air cylinder 4 and pair of cams 6.
Therefore, owing to will open both sides' electrode, particularly to guarantee to be in the electrode of induction tube 7 offsides, promptly be arranged in the mobile space of liquid bath 1 wall lateral electrode 2a at liquid bath 1, so need bigger liquid bath, cost strengthens, and when in existing liquid bath 1, Strip processing device being installed, if when not having this space, must transform to liquid bath 1.
In addition, the downside that must stretch out configured electrodes 2 to the outside of liquid bath 1 from the wall of liquid bath 1 opens and closes the operating portion of using cam 6, promptly in liquid bath 1 upper shed, thereby can cause the problem that liquid leaks.
When observing the actual motion operation, find the overlapping weld part that welds of the band of thickness of slab 1.2mm, and between the stabilizer if the distance of 6mm is arranged, just can lead to plate non-contiguously and operate., the rope the when switch of electrode 2, just logical in the early stage plate by the time just can.Thus, not only can address the above problem, and new save space equipment can be set.
The 2nd problem is to stir about treatment solutions such as electroplate liquids.In above-mentioned Strip processing device, as shown in figure 14, between the stabilizer 8 of electrode 2, be provided with a plurality of open-works 9 (with reference to special fair 6-13759 communique) that are communicated with outside in the electrode.Under this structure situation, when band 10 is passing between electrode 2,2 (not expressing among opposed electrode 2 figure),, cause the fluid that confuses,, cause the fluidic circulation in the inner face side of electrode 2 and exterior side by through hole 9 as the arrow sample 8,8 of stabilizers.Its result becomes the structure that the new fluid of the old fluid of electrode inner face side and electrode exterior side is changed.
This method forms the slow part of flow velocity between open-work and open-work, produces the liquid stream of the uneven striated of flow velocity.And the inhomogeneous liquid of this striated fail to be convened for lack of a quorum cause the chemistry ununiformity.The spacing of cancellation open-work and open-work, opening a vertical slotted hole on direction of travel is to prevent that the miscarriage of striated liquid is living.This method produces the problem on the pole strength, is head it off, must add the size of large electrode.
The 3rd problem is the liquid level stability problem that can cause treatment solution when walking between electrode about band.(this figure (a) is an orthographic plan of removing side's electrode as shown in figure 15; should scheme for easy to understand in addition; cut the part of band); electrodes such as male or female 2,2 mutual intervals are made extremely narrow, when operation shown in Figure 15 (b); along with band 10 moves and entrained liquids to down direction; make interpolar liquid level instability, promptly liquid level knee-action shown in symbol p and q can produce like this and electroplate mottling or clean spot.
Therefore, (this figure (a) is an orthographic plan of removing side's electrode, should scheme for easy to understand in addition as shown in figure 16, cut the part of band), on the top of electrode 2 fluid infusion apparatus 11 is set, injects liquid to interpolar, prevent the instability of liquid level in the interpolar with this method.And then, for purification device like that when the electrifying electrodes, even liquid level water level reduces, the decline of voltage is also very little, and for electroplanting device, liquid level water level reduces, when the distance of conduction roller and water level was elongated, the decline of voltage strengthened, owing to need too much electric power, more liquid need be injected into 2,2 at electrode for improving liquid level water level.
So, need fluid infusion apparatus 11, but on the top of the male or female of being furnished with various devices, pipe fitting etc., and then during the configuration fluid infusion apparatus, will make electroplanting device or purification device extremely complicated.In addition, after stabilizer 8 was set, injecting liquid (Figure 16) at 2,2 at extremely narrow electrode was not a nothing the matter, in order to overcome these problems, and then needed additional various device.Therefore, the cost of electroplanting device or purification device increases, and maintenance also becomes complicated, thus hindered stabilizer (8) is set after, popularizing of narrow electroplanting device of poling or purification device (spy opens flat 3-20494) done at the interval of electrode 2,2.

Effect for the band device that reaches the 1st purpose at first is described.Determine a lateral electrode of the homopolarity electrode of subtend configuration behind the position and fix, the opposite side electrode dispose can switch on-off mechanism.Therefore, when the rope of logical plate of initial stage passes through, only need open the opposite side electrode and just can obtain necessary interpole gap.At this moment, the electrode of a side is owing to be fixed on the position of closing, so during logical in the early stage plate, worry to contact with band, but owing on the pole-face isolator (stabilizer) is arranged, band slides on this isolator, and can not contact with pole-face.In addition, on band, be not added with tension force, so can not destroy isolator (stabilizer) yet.The electrode of liquid bath wall side is made fixed side electrode, and needn't guarantee its mobile space, thus small-sized liquid bath can be used, and, in having the existing liquid bath of this spatial, Strip processing device can be installed yet.Only be mounted on the opposite side electrode owing to on-off mechanism in addition, so can reduce the cost of on-off mechanism.
When homopolarity electrode vertical direction is configured in the liquid bath, the liquid level upside that all being configured in of on-off mechanism operating portion is higher than liquid bath, so there is no need to draw operating portion in the upper shed of liquid bath wall, thereby prevent the leakage of liquid, in addition, prevented that also operating portion is immersed in the liquid, so just prevented the fault of operating portion to take place.Here said operating portion is meant the part of the power that produces driving switch mechanism, when using manual drives, be meant the part that hand acts on, when driving automatically, be meant the motivating force part takes place, just the linear driving part of the rotary transmission part of revolving cylinder etc., air cylinder etc.
On-off mechanism is to have following structure, promptly be supported on the pair of electrodes carriage with a rotatable axle, and fixing cam respectively on the position, both ends of opposite side electrode, and by an end be provided with operating portion camshaft and, be fixed on the both ends of opposite side electrode, and constitute with a pair of framework that the cam meshing of above-mentioned camshaft closes, so can obtain simple mechanism, and the little on-off mechanism that takes up space, in addition the both ends of opposite side are supported in camshaft on the pair of electrodes carriage and switch side by side by axle, so can carry out switch motion exactly.
When homopolarity electrode vertical direction ground subtend is configured in the liquid bath, by be arranged between upside electrode bracket and opposite side electrode bus bars sliding system and, be arranged on the upside electrode bracket, the linear driving member that the opposite side electrode is slided has constituted on-off mechanism, so can be than mobile opposite side electrode under the low-frictional force, therefore just can traveling electrode with very little power, driving member can make compact type.
Below explanation is in order to reach the electroplanting device and the washing unit of the 2nd purpose.In this device, for the current upstream side of the band between stabilizer, liquid becomes negative pressure state.This is because when band is current, and liquid is along the direction of advancing and the mobile cause.Therefore, this part becomes the suction side.Then, by being communicated with the open-work of outside in the electrode, insert the liquid into the electrode inner face from the electrode exterior side.This liquid at first enters in the liquid storage device of the rectification part that is arranged on the suction side.Then in this reservoir, make pressure equalization, be introduced into towards band from the hole of slit-shaped.
At this moment, the liquid stream of drawing from the hole of slit-shaped is uniformly, does not electroplate or cleans so can there be spot.
Then, the downstream side that the band between stabilizer is current, owing to stopping of stabilizer, the pressure of electrode inner face raises, so become the discharge side of liquid, by the open-work outside being communicated with in the electrode, and liquid is discharged to the electrode outside.
In addition, a part of liquid flows to the current upstream side of band along the electrode inner face.
At this moment, because the mobile generation difference of meshed portion and no bore portion, so when the discharge side is provided with rectification part, also can flow equably at the fluid of discharging side.
In addition, in discharging side, spacing by control punch and size etc. also can not need rectification part sometimes.
When rectification part was installed, it is that part of that discharge face only reduces rectification part, if but when making stabilizer double as rectification part, can prevent the minimizing of above-mentioned discharge face.
When utilizing the recess formation liquid storage device on the electrode, can reduce the height of rectification part, during stabilizer double as rectification part, can prevent that with this method the height of stabilizer from increasing, so can keep short pole distance.
Rectification part makes with heat-stable material and/or drug-resistant material.Owing to being heated or medicine is out of shape, keep the function of rectification part so can prevent rectification part.In addition, rectification part distortion back and phenomenons such as band contacts have been prevented.
The double as rectification part is set on electrode or rectification part to be installed the hole of usefulness and eliminates the hole of extending owing to the thermal expansion of rectification part etc.Thus, though the material of rectification part and electrode different (or because of thermal expansion differences), or, therefore can prevent that rectification part from contacting with band because the rectification part swelling also can prevent the deflection deformation of rectification part.
Below explanation is for the electroplanting device that reaches the 3rd purpose and the effect of washing unit.To liquid, flow into ion or adhere to ion at the discharge face of negative electrode and electroplated afterwards or cleaned from the anodic discharge face, but because the upper end position of the discharge face of male or female is positioned at the liquid level lower position of liquid bath, so the discharge face part necessarily is present in the liquid, therefore can have spot and electroplate or clean.

Embodiment
Describe in detail at first with reference to the accompanying drawings to reaching the embodiment of the 1st purpose.Shown in Fig. 1 (a), storing in vertical bath formula liquid bath 1 has electroplate liquid (omitting among the figure), and in this electroplate liquid, vertically subtend is disposing anode electrode 2,2, and makes its top 2d be arranged in the upside of liquid bath 1 liquid level (figure omits).The outstanding isolator (stabilizer) that is provided with of the inner face of electrode 2, along the place ahead (below of figure) of the current direction of band, isolator forms from the oblique conical surface (omitting the figure) of electrode side direction band inclination.The upper end of electrode 2 is installed with bus 2c, powers with this.
In addition, the opposite side electrode 2a at the homopolarity electrode of subtend configuration is being fixed.Be upside electrode bracket 3, downside electrode bracket 5, behind the position of having determined bus fitting portion 3a, 5a disposed thereon, be fixed in the liquid bath 1, be arranged on the bus 2c of the upper and lower ends of opposite side electrode 2a, be entrenched among bus fitting portion 3a, the 5a, be fixed with this back, position of determining opposite side electrode 2a.Moreover upside electrode bracket 3 is positioned at the liquid level upside of liquid bath 1.Opposite side electrode 2a also can be fixed near the wall side of liquid bath 1.
Then, the last side bus 2c of opposite side electrode 2b is positioned on the upside electrode bracket 3 slidably, and therefore for a lateral electrode 2a, becoming can on off state.On the other hand, linking part 3b, the 5b that can determine opposite side electrode 2b closing condition position is arranged on the upper/lower electrode carriage 3,6.And on opposite side electrode 2b, be provided with on-off mechanism 20.Just, camshaft 20a is supported in up and down on the pair of electrodes carriage 3,5 with the axle of rotation, and is fixing cam 20b respectively on the end positions of opposite side electrode 2b, and in the upper end, is fixedly installing the operating portion 20c that is made of hand lever.Operating portion 20c is positioned at the upside of liquid bath 1 liquid level.And cam 20b is shown in Fig. 1 (b), it is discoideus and eccentric cam, the direction of hand lever 20c made with the electrode side meet at right angles under the state of direction, when opposite side electrode 2b is expressed to the state of contact part 3b, 5b, electrode a for a side closes, when the direction of hand lever 20c is made the state parallel with electrode surface, with framework 20d described later together, make opposite side electrode 2b be in the state opened for a lateral electrode 2a.Moreover the size that sets of the offset of eccentric 20b, only make because moving of opposite side electrode and aperture that rope is passed through.Framework 20d is by being fixed on the bus 2c, and is arranged on the both ends of opposite side electrode.Framework 20d is a rectangle, and has the width with cam 20b equal diameters, and cam 20b is entrenched among the framework 20d.Can be with combining when therefore, the position of eccentric wheel 20b changes at its position upper frame body 0d.
The bottom of liquid bath 1 is disposing induction tube 7, at the strip coil that walks in 2,2 of pair of electrodes on induction tube 7 and change direction.
By such structure, when logical plate rope of the initial stage of carrying out by the time, move hand lever 20c after, make its direction parallel with electrode surface (dotted line of Fig. 1 (b)).So in two sides of the upper end of opposite side electrode and bottom, because framework is along with eccentric wheel moves, so open the opposite side electrode.At this moment, the upper end of opposite side electrode and the both sides of bottom are opened, and positively become open and-shut mode.In addition, only the hand lever 20c by operating the liquid level upside just can, so can easily operate.In addition, a lateral electrode is owing to be fixed on the position of closing, so contact with band when worrying logical in the early stage plate, still because of on the pole-face isolator (stabilizer) arranged, so band sliding contact on this isolator can not contact with pole-face.On band because any tension force in addition not, so can not destroy isolator.
Then, under this state,, and, then move hand lever 20c, make its direction vertical with electrode surface (solid line of Fig. 1 (b)) with responding to the direction that tube 7 changes bands by the rope of logical plate of initial stage.So with above-mentioned the same, framework 20d is along with eccentric wheel 20b, move towards reverse direction when opening, opposite side electrode 2b closes.At this moment, the opposite side electrode finishes closing movement with after contact part 3b, 5b contact, and because eccentric wheel 20b further is crimped on bus 2c on contact part 3b, the 5b, can contact exactly.In addition, the rotation of hand lever 20c during this owing to set the specified length of hand lever 20c, just can be carried out with very little power according to lever principle.
After logical so in the early stage plate rope passage finishes, use the electrode 2 at narrow interval, can carry out the plating of high current density band.
Then,, as required, can open opposite side electrode 2b once more, it is passed through when by because welding waits when having the band of thick connection portion, then once more with the above-mentioned plating of similarly carrying out high current density.

Figure 12 (a) is an orthographic plan of removing side's electrode, cuts for a part that is easy to interpret blueprints band in addition.Figure 12 (b) is a side-view.It is the orthographic plan and the side-view of bus and electrode that Figure 12 (c) reaches (d).
In the figure (a) and (b), storing electroplate liquid or scavenging solution 80 in the liquid bath (omitting among the figure), electrode 2 is that subtend is disposing,
Shown in this figure (c), (d), at the interior side-prominent stabilizer 8 that is being provided with of electrode 2, on stabilizer 8, the place ahead along the direction of travel of band forms one from the oblique conical surface 8a of electrode side direction band inclination.And suspending electrode 1 in midair and flowing through the bus 82 of electric current, near suspention electrode 2 positions, make surface insulation, and slightly be the bending of U font below with the material of regulation.And on this bend 84, suspending electrode 2 in midair.In addition, the multiple layer of quilt that does not have isolator on the electrode 2.The crooked degree of depth of the bend 84 of bus 82 is determined according to following principle, i.e. suspention when hanging with the bus 82 of this electrode 2 in liquid bath, the upper end that the make electrode 2 just lowest positions r of the multiple portion of quilt of bus 82 is in than on the also low lower position of the q bottom of liquid level change in the interpolar.
Then, conduction roller (omitting among the figure) is set above electrode 2, behind the band 10 contact conduction rollers, moves, between bus 82 and conduction roller, power in 2 downward directions of counter electrode.
According to such formation, when band moved, because interpolar is narrow, the liquid level that makes in the interpolar of carrying secretly of liquid descended, and changes between position, the top P and lowest positions q.The upper end r of discharge face, therefore, can not have spot and electroplates or clean so discharge face necessarily is present in the liquid owing to be positioned at the downside of the lowest positions q that is lower than the liquid level change.
In the present embodiment, the bus 82 of surface insulation is bent to the liquid level downside, its downside is suspending electrode in midair, thus be higher than electroplate liquid level with top, can prevent that band from contacting with electrode and produce scar etc.And then, because crooked, can make the water level of conduction roller and liquid level approaching, can reduce loss of voltage, but so also conservation of power.
The present invention since make just the opposite side electrode can switch, so there is no need to guarantee a lateral electrode mobile space, therefore can use little liquid bath.In not having the existing liquid bath of this spatial, the Strip processing device that is provided with stabilizer can be installed in addition.Can enlarge the scope of utilizing of this Strip processing device.Because on-off mechanism only is mounted on the opposite side electrode, so the cost of on-off mechanism reduces half.
When being configured in homopolarity electrode vertical direction ground subtend in the liquid bath, because the operating portion of on-off mechanism is configured in the upside of liquid bath liquid level all, so there is no need to draw operating portion in the upper shed of liquid bath wall, thereby can prevent that liquid from leaking, prevented that in addition operating portion is immersed in the liquid, so prevented the fault of operating portion.
Because the rectification part in the hole with liquid storage device and slit-shaped is set, so the hole by slit-shaped, liquid contacts with band, makes uniform liquid flow and contact with band not have the plating or the cleaning of spot among the present invention.
In addition, among the present invention, the upper end position of the discharge face of male or female is positioned at the liquid level downside of liquid bath, so no matter how liquid level changes plating or cleaning that also can not have spot.Simultaneously, the formation of device is extremely simple, therefore, can extremely easily implement the present invention at low cost, in addition, maintains also extremely simple.Thereby, will obtain very big popularizing along the outstanding electroplanting device and the washing unit that have from the male or female subtend configuration of electrode side direction band inclination scalene cone isolator of being provided with of band direction of travel.
