The specific embodiment
Below use Fig. 1～Fig. 3 to specify the DF coating machine of embodiment of the present invention.
Fig. 1 is the figure of overview of the DF coating machine 1 of expression embodiment of the present invention.
As shown in Figure 1; DF coating machine 1 possesses: the intrasystem supplying tank 10 that is used for coating 2 is supplied to DF coating machine 1; Be configured in this supplying tank 10 the downstream, be used to remove at the deaeration machine 12 of the coating 2 inner bubbles that produce and the DF coating machine in downstream that is disposed at this deaeration machine 12 with 14.
In addition, DF coating machine 1 possesses return tank 16, and this return tank 16 is positioned at the DF coating machine with 14 downside, is used to store from the DF coating machine flow down the coating 2 that the back is collected by drain pan 15 with 14.
And then; DF coating machine 1 possesses: supply with and to deliver to the dilution flow container 18 of DF coating machine with the dilution 3 in 14; Be configured in a plurality of by-pass valve controls 21 on the pipe arrangement 20 that connects this dilution flow container 18 and DF coating machine usefulness 14; The downstream that is used to control the control module 22 of above-mentioned by-pass valve control 21 and be positioned at the direction of travel of the base material that transports for coating (being in a ratio of the downstream with 14), detect the thickness of filming after coating base material, the scanner 23 of level ground number (perhaps coating weight) at the width of base material with the DF coating machine.
Should explain that above-mentioned by-pass valve control 21 is the valves that can threshold switch be adjusted the flow of dilution 3 based on control signal, for example can use electromagnetic switch valve, electric valve etc.In addition, also can use extruding rubber tubulation and the pinch valve of adjusting flow waits the flow of adjusting trace.
Fig. 2 be represent briefly to the DF coating machine with 14 supply with the structure of dilutions 3 an ideograph, Fig. 3 is a DF coating machine shown in Figure 2 with the sectional view of 14 A-A line.
As shown in Figure 2, the DF coating machine (transports and the width of the base material that comes at the paper left and right directions with 14.That is, base material from the paper of Fig. 2 nearby side direction paper depths side transport) form strip, its length is longer than the length of the width of base material.
In addition, this DF coating machine with 14 shown in the sectional view of Fig. 3 combination 2 members (member 14a, member 14b) and constituting.In member 14b, form the concave part that extends along its length on composition surface with member 14a, under the state (state of Fig. 3) of assembling this member 14a and member 14b, this concave part is constituted coating chamber 31 by obturation.
As shown in Figure 2, from the coating inlet 32 of the paper right-hand end that is arranged at length direction coating 2 is injected in these coating chamber 31.Injection utilizes above-mentioned deaeration machine 12 (referring to Fig. 1) to carry out deaeration and utilizes the 2nd circulating pump 13 to transport and next coating 2 in this coating inlet 32.Should explain that the both side ends of coating chamber 31 can not spilt coating 2 by not shown obstruction component obturation.
And then, the DF coating machine with 14 in, form the gap that extends to downside from coating chamber 31 down in the state of combined member 14a and member 14b, constitute spray nozzle part 33 by this gap.This spray nozzle part 33 likewise forms slit-shaped along its length continuously with coating chamber 31.Thus, the coating that flows down through spray nozzle part 33 from coating chamber 31 relies on deadweight to flow down from the bottom of spray nozzle part 33 and forms the curtain film.
Further, the DF coating machine is with 14 as Fig. 2 and shown in Figure 3 is formed at member 14a and be communicated to a plurality of supply ports 30 in the coating chamber 31 from the outside of member 14a towards the formation of general horizontal direction ground.This supply port 30 is as shown in Figure 2 roughly uniformly-spaced to be formed on straight line along its length (about 50mm spacing in this embodiment).In addition, the aperture position of above-mentioned supply port 30 be member 14a the outside planar portions and be disposed at respectively coating chamber 31 near, thereby make the handling ease of this supply port 30.
Should explain that supply port 30 needn't be provided with being arranged in a straight line, shape of the planar portions in the outside that also can mating component 14a etc. and disposing alternately at above-below direction.But, must be at the DF coating machine with 14 roughly equally spaced configuration of width.In addition, though supply port 30 is formed towards horizontal direction, so long as the direction of handling ease, also can be towards above-below direction.
As shown in Figure 2, pipe arrangement 20 Jie that also connect from dilution flow container 18 branches are connected to above-mentioned a plurality of supply port 30 by by-pass valve control 21.Should explain that supply port 30 is situated between with pipe arrangement 20 and is connected respectively by not shown attaching nut, becomes the watertight structure that can not spill dilution 3 from this supply port 30.
In addition, control module 22 and carry out wiring through distribution 24 respectively corresponding to the by-pass valve control 21 of each supply port 30 can be through control module 22 gauge tap action respectively separately.That is, can individually in coating chamber 31, supply with dilution 3 or carry out the flow adjustment by which supply port 30 arbitrarily.
Above-mentioned supply port 30 formation toroidals as shown in Figure 2.Its shape depends on that supply port 30 uses drill bits etc. to process or be used to easily install above-mentioned attaching nut's female screw thread processing etc. easily.
In addition, the details of above-mentioned dilution 3 are described, can be changed the concentration of coating 2 and change the coating weight of dried coated face, for example can make the coating (reduce the concentration of coating 2 and obtain coating) of water or low concentration etc.But if the concentration difference of the concentration of dilution 3 and coating 2 is too greatly different, then dilution 3 is difficult to mix in coating chamber 31 with coating 2, possibly on the face of curtain film, form striped.So, the coating that dilution 3 preferred working concentrations are more lower slightly than coating 2.
With the coating of this low concentration during as dilution; For example shown in Figure 5, be provided for water 103 is supplied in the dilution flow container 18 and coating 3 branches that will between deaeration machine 12 and DF coating machine are with 14, flow and introduce pipe arrangement 120, pump 113 and the static mixer 125 of pipe arrangement 20.This pump 113 realizes coating 3 is sent into the function of static mixer 125, and static mixer 125 performances make from the dilution flow container 18 interior water of sending here via the 4th circulating pump 19 103 and mix with coating 3, and pass out to the function of pipe arrangement 21.In addition, valve 130 (can be type hand, also can be control type) can be set also at the upstream side of pump 113, the influx of adjustment coating 2, thereby the concentration of adjustment dilution.
Then, use Fig. 1～Fig. 3 that the effect of the DF coating machine 1 of embodiment of the present invention is described.
In DF coating machine 1, the base material before the coating that is rolled into web-like (symbol 51 shown in Figure 6) with take-off device (not shown) uncoiling, is rolled into web-like through coiler device (not shown) once more.At this moment, the base material side of uncoiling is walked the limit at a high speed through curtain film, the surface coated of this base material at the DF coating machine with 14 downside.
When being coated with DF coating machine 1; As shown in Figure 1, at first, coating 2 is supplied to (referring to Fig. 1) in the supplying tank 10; After removing the bubble in the coating 2 by deaeration machine 12 (referring to Fig. 1), the coating after the deaeration 2 is sent into the DF coating machine with the coating chamber 31 in 14.Coating 2 injects from the coating inlet 32 (referring to Fig. 2) of the end of the length direction of coating chamber 31.
At this moment, in the coating 2 in coating chamber 31, in everybody of the length direction of the coating chamber 31 living difference in flow (for example flow becomes many in the end of the coating chamber 31 of injecting coating 2, and along with away from this end, flow reduces) of buying property.Make coating 2 from the DF coating machine during under this state with 14 membranaceous the flowing down of 33 one-tenth curtains of spray nozzle part; Because of this difference in flow make the shape of curtain film take place chaotic (part that for example flow is many under the thicker of curtain film, the thin thickness of the curtain film under the part that flow is few).And then, when being coated with, at coated face generation crawling or deep or light (color of the part that for example flow is many is dense, and the color of the part that flow is few is shallow) of substrate surface through such curtain film.
So,, reduce the concentration of the coating of the many parts of flow through in coating chamber 21, supplying with dilution 3 from the supply port 30 of the many parts of flow.Thus, in the many parts of flow, coating is thinning because of dilution 3.But the quantitative change of coating (make the base material that is applied dry and make the coating that remains in the reality of coated face after the water evaporates) of coating the essence of base material is few.So coating content basic identical (evenly) with the essence of the few part of flow becomes.So can be adjusted at the coating weight of the dried whole coated face of hothouse equably.
Supplying with the method for dilution 3 can carry out through manual operation, also can based on from the control signal of control module 22 with by-pass valve control 21 switches, supply with.
In addition; The part that flow is many, promptly need supply with the judgement of the supply port 30 of dilution 3 can be through every flows of measuring time per unit at a distance from each spacing (each position of supply port 30) such as for example not shown flowmeters; Obtain flow profile at the width of base material; Adjust repeatedly, measure based on this, judge best supply position.In addition, can determine the supply position of dilution 3 based on the knowledge that obtains by rule of thumb, can also be based on confirming from the detection signal of scanner 23.
Situation by rule of thumb is meant the situation that can grasp the part more than the flow according to the length of the for example length direction of coating chamber 31, the kind etc. that supplies to the coating 2 in the coating chamber 31 in advance by rule of thumb.At this moment, do not use control module 22 or scanner 23 just can confirm to supply with the supply port 30 of dilution 3.In this case, operating personnel can supply with dilution 3 through manual operation.In addition, can the information issuing that rely on these experiences to be grasped in advance be become program, use the CPU control by-pass valve control 21 in the control module 22 to make its automatic switch.
In addition, under the first situation of using such as coating 2, perhaps want to carry out under the situation such as management of coated face tightlyer, also can use scanner 23 or control module 22 to carry out FEEDBACK CONTROL.In detail, can use scanner 23 to detect thickness of filming or the coating weight (perhaps level ground number) of coating substrate surface, confirm supply port 30 corresponding to this uneven part at the width of base material (DF coating machine with 14 length direction).Thus, can carry out FEEDBACK CONTROL to the switch of supply port 30 based on the state of filming of substrate surface etc.
DF coating machine 1 according to the embodiment of the present invention; Because it is a plurality of and be communicated to the supply port 30 in the coating chamber 31 from the DF coating machine with 14 the outside that the DF coating machine is provided with devices spaced apart configuration along its length with 14; The dilution 3 that this supply port 30 is used for dilution is stored in the concentration of the coating 2 in the coating chamber 31 supplies in the coating chamber 31; So the part through the flow of the coating 2 in coating chamber 13 is many is supplied with dilution 3, thereby can reduce the concentration of the coating 2 of the many parts of this flow.Thus, with dilution 3 dilutions, can make the amount of the coating that is applied in the essence of base material (dry back water evaporates and remain in the coating of the reality of coated face) roughly even through the part that the part of the thicker of curtain film and flow velocity is fast.So after making the base material drying, the coating that residues in base material becomes roughly even, coated face is difficult to occur deep or light and uneven.Therefore, do not make die lip 55 (referring to Fig. 6) carry out tractive action and the thickness of adjustment curtain film just can make the coated face of base material be difficult to occur deep or light and uneven.
In addition; Can be because on the pipe arrangement that is connected in supply port 30 20, be provided with respectively based on the by-pass valve control 21 of adjusting the quantity delivered of dilution 3 from the signal of control module 22, so can dilution 3 suitably be supplied to the many parts of flow of the coating 2 in the coating chamber 31.Thus, the thickness of not adjusting the curtain film just can make the coated face of base material be difficult to occur deep or light and uneven.
And then, because supply port 30 for the DF coating machine with the planar portions in 14 the outside and be respectively formed at coating chamber 31 near, so can easily carry out the processing of supply port 30.In addition because be respectively formed at coating chamber 31 near, so can be by supply port 30 is processed from the mode that planar portions easily is communicated to coating chamber 31.
In addition; Because have detection at the thickness of the width of the base material that is applied or the scanner 23 of coating weight; Control module 22 carries out FEEDBACK CONTROL based on the information of sending from scanner 23 to each by-pass valve control 21; Even so producing under the situation of uneven (confusion) on the face of curtain film, also can revise automatically through control module 22 should inequality.The thickness that the result does not adjust the curtain film just can make the coated face of base material be difficult to occur deep or light and uneven.
More than the DF coating machine 1 of embodiment of the present invention is described, but the present invention is not limited to above-mentioned embodiment, can carry out various distortion and change based on technical conceive of the present invention.
For example in this embodiment, the shape with supply port 30 as shown in Figure 2 forms toroidal, but also can be shown in Fig. 4 (a) and Fig. 4 (b), and the shape of supply port 300 is formed slotted hole 301 (slotted hole of shape of slit).More in detail, the part that supply port 300 will be installed attaching nut (not shown) forms circular hole, and will become slotted hole 301 towards the hole shape of coating chamber's 31 1 sides.This slotted hole 301 forms with 14 length direction mode unanimous on the whole with its long axis direction and DF coating machine, and its shape can be elliptical shape, also can be for having the rectangular shape of length direction.
Through being this long hole shape; When the dilution 3 that supplies to supply port 300 is admitted in the coating chamber 31; Shape with based on slotted hole 301 is supplied with the mode of the length direction diffusion of 140 (being made up of member 140a, 140b) at the DF coating machine; Thereby for the coating 2 that is stored in the coating chamber 31, the concentration that can dilute wider coating 2.In addition, through being long hole shape, the slotted hole of adjacency reduced distances each other can make the scope of supplying with dilution 3 bigger.And then, needn't make the spacing of supply port 300 short excessively.
In addition, on flow container 18 and the pipe arrangement 20 that a plurality of supply ports 30 are connected by-pass valve control 21 is set and controls will diluting, but also can use the hand switch valve of manual adjustment.At this moment, operating personnel confirm to coat the state that filming of base material waited, and decision is to which supply port 30 supply dilutions 3 of the width of base material, through manually coming the valve of this part of switch.
And then in this embodiment, for the supply method of coating 2 and dilution 3, with coating 100%: dilution 0% be basis, only carries out the adjustment that the part more than the flow is diluted.On the contrary; Also can take following adjustment method: the coating 2 that for example flows out 90% amount of final flow all the time from coating inlet 32; Flow out simultaneously 10% dilution 3 all the time from supply port 30, further reduce the amount of dilution of the few part of flow and increase coating weight.Thus, can reduce the position of adjustment in advance.
