Abstract

Web treatment apparatus 1 has two process tanks 2,3, each with respective upper and lower bearing fluid bearings 21,22; 31,32. In use, a web 4 passes sinuously around them for treatment with chemical solution 23 in tank 2 and washing with water 33 in tank 3. Respective substantially identical air knives 5,6 are provided at the outlet from tank 2 / inlet to tanks 3 and at the outlet from tank 3. The web 4 is passed around a plurality of other fluid bearings 10, which guide it in and out of the tanks.
Each air knife is comprised of four parts, up- and down-stream parts 71.72 fixed together as a lower member 7 and like parts 81,82 fixed together as an upper member 8. The up-stream parts 71,81 have plain mating faces 73,83; whilst the down-stream parts 72,82 have machined faces 74,84 providing air supply plenum chambers 75,85 air supply slots 76,86, inner plenum chambers 77,87 and air knife slits 78,88. Non-shown means is provided for supply of air to the plenum chambers 75,85 whereby extended air jets exit the slits 78,88 towards each other. They impinge on the web when between the air knife members.
From the slits, the air flows along the top and bottom 41,42 faces of the web. The air flow exits the air knife in the up- and down-stream direction, passing out from between opposed faces 79,89 of the knife members. In doing so the air blows away any droplets tending to be drawn in between the members.
The grooves 9 comprise up- and down-stream, opposed semi-circular grooves 91,92 in the opposed faces 79,89. I believe that they operate as plenum chambers thoroughly equalising the pressure and flow of the air over the faces 41,42 of the web 4 outwards of them. The grooves improve evenness of drying.

Description

液體移除裝置 liquid removal device

本發明係關於用於自幅材移除液體之裝置，且詳言之(但非排他地)，用於在處理台內圍阻液體及避免液體由幅材自處理台攜載之裝置。 The present invention relates to a device for removing liquid from a web, and in particular (but not exclusively), a device for containing liquid within a processing station and preventing it from being carried by the web from the processing station.

類比於隔離閥將此圍阻及避免攜載稱作「隔離」。 This containment and avoidance of carryover is called "isolation" in analogy to an isolation valve.

藉由移除液體，意欲移除大量液體及/或液體液滴，亦即，表面乾燥。通常不期望移除大量液體及液滴液體導致完全乾燥。物質可保持潮濕或潤濕或攜載微觀液體，儘管為表面上乾燥的。因此，對「隔離」之引用包括表面隔離，且不限於如同醫院隔離病房之至最大範圍可能的隔離。 By removing liquid, it is intended to remove a large amount of liquid and/or liquid droplets, ie the surface is dry. It is generally not desirable to remove large amounts of liquid and droplets of liquid resulting in complete drying. Substances may remain moist or wet or carry microscopic liquids despite being superficially dry. Thus, references to "isolation" include superficial isolation and are not limited to isolation to the greatest extent possible as in a hospital isolation ward.

已知經由儲槽將幅材藉由溶液中化學成分進行處理。舉例而言，已知以無電極方式將銅鍍敷至聚合物幅材上以供在諸如觸控式螢幕中使用。幅材可能需要自具有一種化學物質之溶液的儲槽傳遞至另一儲槽，在此情況下，不使一種化學物質自其儲槽攜載至第二化學物質之儲槽為重要的。換言之，具有一種化學物質之液體應與具有另一化學物質之液體隔離。此外，在清洗槽設置於化學物質槽之間的情況下，化學物質液體應與清洗液體隔離。 It is known to treat webs with chemicals in solution via storage tanks. For example, electrodeless plating of copper onto polymeric webs is known for use in, for example, touchscreens. The web may need to be transferred from a storage tank with a solution of one chemical to another storage tank, in which case it is important not to carry one chemical from its storage tank to the second chemical storage tank. In other words, liquids with one chemical should be isolated from liquids with another chemical. Furthermore, in the case where the cleaning tank is provided between the chemical tanks, the chemical liquid should be isolated from the cleaning liquid.

可藉由在槽之間使用幅材乾燥機來避免化學物質之夾帶。然而，鑒於已在英國專利申請案第GB 2,500,564號中使用數個重疊空氣軸承類型乾燥導引件，轉移台可為大體積的，且實際上涉及不均勻乾燥之風險。不均勻乾燥可引起與例如鍍敷液體之不均勻接觸，且因此引起不均勻鍍敷。 Entrainment of chemicals can be avoided by using a web dryer between the tanks. However, given that several overlapping air bearing type drying guides have been used in UK Patent Application No. GB 2,500,564, the transfer table can be bulky and in practice involves the risk of uneven drying. Uneven drying can cause uneven contact with, for example, the plating liquid, and thus uneven plating.

已將氣刀用於自焊料整平至板乾燥之許多應用中。然而，對於將標準氣刀用於幅材乾燥並不覺得有信心。 Air knives have been used in many applications from solder leveling to board drying. However, I do not feel confident using standard air knives for web drying.

「氣刀」在本發明上下文中意謂：具有對置表面之一對對置構件，該等對置構件各自具有空氣可吹過之狹縫或孔隙之線性陣列，用於在通過方向中自於對置構件之間通過的板、片或幅材(「幅材」偶爾單獨用以包括此等各者中之任一者)之對置表面吹除液體。 "Air knife" in the context of the present invention means: a pair of opposing members having opposing surfaces, each having a linear array of slits or apertures through which air can be blown, for freeing in the passing direction The opposing surfaces of a plate, sheet, or web ("web" is occasionally used alone to include any of these) passing between opposing members is blown away with liquid.

通常，狹縫或孔隙將成角以與幅材之行進方向相反地導引氣流，藉此將液體朝向用液體對幅材進行處理所在之區域吹回且幅材係自該區域行進，攜載殘餘液體。 Typically, the slits or apertures will be angled to direct the airflow against the direction of travel of the web, thereby blowing the liquid back towards the area where the web is being treated with the liquid and from which the web travels, carrying residual liquid.

本發明之目標為提供用於液體移除之改良型裝置。 It is an object of the present invention to provide an improved device for liquid removal.

根據本發明，提供一種液體移除裝置，其包含：一氣刀，其在一對對置構件之對置表面中的至少一者中具有至少一個細長凹槽或槽口，該凹槽或槽口就通過方向而言在該各別狹縫或孔隙之線性陣列上游或下游。 According to the present invention, there is provided a liquid removal device comprising: an air knife having at least one elongated groove or notch in at least one of the opposing surfaces of a pair of opposing members, the groove or notch Either upstream or downstream of the respective linear array of slits or apertures with respect to the direction of passage.

通常，幅材在該通過方向中將比其橫向寬度長。該氣刀將具有橫向於該通過方向的比該幅材之寬度長的長度，但在其通過方向中相較 於其長度狹窄。 Typically, the web will be longer in this passing direction than its transverse width. The air knife will have a length transverse to the pass direction that is longer than the width of the web, but compared in its pass direction narrow in its length.

如此，該或各細長凹槽或槽口將至少實質上平行於該各別狹縫或孔隙之線性陣列。 As such, the or each elongated groove or slot will be at least substantially parallel to the respective linear array of slits or apertures.

在一或多個凹槽之情況下，該或各對置表面延伸超出該凹槽，該凹槽至少實質上在該各別狹縫或孔隙之線性陣列處與自身齊平。 In the case of one or more grooves, the or each opposing surface extends beyond the groove, the groove being at least substantially flush with itself at the linear array of the respective slits or apertures.

該等凹槽宜成對地提供，一個凹槽在一個對置表面中，另一凹槽在另一個對置表面中。較佳地，此等凹槽將彼此對置地對準，以將幅材在該等對置表面之間集中地保持在凹槽之間。然而，該等凹槽可能交錯。 The grooves are preferably provided in pairs, one groove in one opposing surface and the other groove in the other opposing surface. Preferably, the grooves will be aligned opposite each other to centrally retain the web between the grooves between the opposing surfaces. However, the grooves may be staggered.

通常，與多對對置凹槽相比較，期望提供單對對置凹槽。可能存在該等狹縫或孔隙之單對上游或單對下游。在不尋常配置中，設想使用與一平面對置構件相對之一上游凹槽及/或一下游凹槽。替代地，將細長凹槽提供為多對對置凹槽。 Typically, it is desirable to provide a single pair of opposed grooves, as opposed to multiple pairs of opposed grooves. There may be a single pair upstream or a single pair downstream of the slits or pores. In unusual configurations, it is envisaged to use an upstream groove and/or a downstream groove opposite a planar opposing member. Alternatively, the elongated grooves are provided as pairs of opposing grooves.

在一或多個槽口之情況下，該或各槽口遠離該各別狹縫或孔隙之線性陣列朝外延伸至有槽口的對置構件之一邊緣。該槽口可橫跨其寬度具有恆定深度或具有變化深度。該槽口之該寬度可大於該槽口與該或各狹縫或孔隙之線性陣列之間的該對置表面之範圍。 In the case of one or more slots, the or each slot extends outwardly away from the linear array of respective slits or apertures to an edge of the slotted opposing member. The slot may have a constant depth or a varying depth across its width. The width of the slot may be greater than the extent of the opposing surface between the slot and the linear array of or each slit or aperture.

通常，一凹槽或槽口在該等對置構件中之一者的該等對置表面中之一者上的存在將由凹槽或槽口在另一對置構件之對置表面中在類似或鏡像位置中的存在反映，藉此在使用中該幅材在兩側上類似地起作用。 Typically, the presence of a groove or notch on one of the opposing surfaces of one of the opposing members will be determined by the presence of a groove or notch in the opposing surface of the other opposing member in a similar Or presence mirroring in a mirror image position whereby in use the web acts similarly on both sides.

再次，通常該等對置表面將 Again, usually the opposing surfaces will be

●在其遠端邊緣處倒角及/或 chamfering and/or chamfering at its distal edge

●至少實質上平坦。 ● At least substantially flat.

此外，該等對置表面之分離在該或各凹槽外部比在凹槽內部大，藉此，當氣流在該(等)凹槽與該狹縫或孔隙線之間使用中，該氣流在該(等)凹槽之朝外比朝內慢。 Furthermore, the separation of the opposing surfaces is greater outside the groove(s) than inside the groove, whereby, when the air flow is in use between the groove(s) and the slit or aperture line, the air flow is The groove(s) are slower towards the outside than towards the inside.

亦即，在一個對置構件為彎曲的、較佳地至少部分地為圓柱體圓形，該對置構件可為平面的而無槽口，亦無凹槽，特別在該彎曲構件為在一幅材之曲度內越過其之一軸承構件之情況下。在此情況下，該另一對置構件可互補地彎曲，但不必如此。 That is, where an opposing member is curved, preferably at least partially cylindrically circular, the opposing member may be flat without notches or grooves, particularly where the curved member is a In the case of passing over one of its bearing members within the curvature of the web. In this case, the other opposing member may be bent complementary, but need not be so.

在一特定彎曲軸承構件具體實施方式中，內部對置構件具有一中心狹縫或孔隙陣列以供空氣提供任一側上之液體隔離，具有用於在該空氣狹縫或陣列上游及下游的各別液體之其他孔隙。 In one particular flexural bearing member embodiment, the inner opposing member has a central slot or array of apertures for air to provide liquid isolation on either side, with separate slots for upstream and downstream of the air slot or array. Other pores of other liquids.

就對置構件而言，包括已在對置表面處切削兩個部件以提供一狹縫且該等部件已固定在一起以提供一對對置構件之單一構件的情形。 In relation to opposing members, this includes situations where two parts have been cut at the opposing surfaces to provide a slit and the parts have been secured together to provide a single member of a pair of opposing members.

設想在兩種液體之間使用該液體移除裝置。因此，應強調使用「隔離」，如同液體移除氣刀之相對側上的液體隔離，以指代存在兩種液體(一種液體在一側上且另一種液體在另一側上)的情形，藉由移除在該幅材移動至氣刀中時流動至氣刀中的上游液體及防止下游液體自氣刀之下游側向上游回流而維持隔離該等液體。換言之，液體移除提供兩種液體彼此之隔離。 It is envisaged to use the liquid removal device between two liquids. Therefore, the use of "isolation", as in liquid isolation on opposite sides of a liquid removal air knife, should be emphasized to refer to the situation where two liquids are present (one on one side and the other on the other), The isolation of the liquids is maintained by removing upstream liquid flowing into the air knife as the web moves into the air knife and preventing downstream liquid from flowing back upstream from the downstream side of the air knife. In other words, liquid removal provides isolation of the two liquids from each other.

應亦強調，有凹槽之氣刀及有槽口之氣刀，或實際上氣刀之有凹槽側及氣刀之有槽口側，將通常用於不同情形中；亦即，在液體與氣刀之一側接觸之情況下，該側將具有凹槽，而在液體不與該側接觸之情況下，該側將具有槽口。 It should also be emphasized that fluted air knives and notched air knives, or indeed the fluted side of air knives and the notched side of air knives, will generally be used in different situations; that is, in liquids. In the case of contact with one side of the air knife, this side will have grooves, and in the case of liquid not in contact with this side, this side will have notches.

當一氣刀側面在一幅材向上或向下移動的情況下與自上方流動之液體接觸，或在一幅材向上或向下移動的情況下在一自由表面位準下方再次與下方液體接觸，或實際上在該幅材水平地移動的情況下在一自由表面位準下方與任一側或兩側上之液體接觸；接著在此等情形中之任一者中，且詳言之在幅材移動之方向便於將液體攜載至氣刀中的情況下，觀察到，儘管液體必須抵抗凹槽外之氣流而在該等對置構件之間傳遞，但一些液體仍可進入凹槽中。然而，該等凹槽用以使該氣刀之中心區域與該液體隔離。至凹槽中之氣流排出進入凹槽中之任何液體且使液體返回其來自之處。 When the side of an air knife comes into contact with liquid flowing from above with a web moving up or down, or again below a free surface level with a web moving up or down, or actually in contact with liquid on either or both sides below a free surface level with the web moving horizontally; then in either of these cases, and in detail in the web Where the material is moved in a direction that facilitates the carrying of liquid into the air knife, it was observed that some liquid can enter the groove although the liquid must pass between the opposing members against the gas flow outside the groove. However, the grooves are used to isolate the central region of the air knife from the liquid. Air flow into the grooves displaces any liquid that enters the grooves and returns the liquid to where it came from.

氣流在該幅材之兩側上及在該氣刀之該上游及下游側上通常將對稱。因此傾向於在幅材之自身中心支撐該幅材，其中氣刀之中心部分充當一空氣軸承。在凹槽外側，液體有助於在該等對置構件之中心軸承支撐該幅材。液體傾向於進入且再次排出，且在此過程中參與保持該幅材與該等對置構件間隔開。 The airflow will generally be symmetrical on both sides of the web and on the upstream and downstream sides of the air knife. There is thus a tendency to support the web at its own center, with the central portion of the air knife acting as an air bearing. Outside the grooves, the liquid helps support the web at the central bearing of the opposing members. Liquid tends to enter and exit again, and in the process participates in keeping the web spaced from the opposing members.

已發現，在幅材來自一無液體區域或傳遞至一無液體區域之情況下，在該等情境中之任一者中，不存在需要彼此隔離之兩種液體存在，將凹槽併入至對置表面中可允許幅材顫動而與該等對置構件接觸。在此等情形下，較佳使用有槽口之氣刀或氣刀之有槽口側。該等有槽口的對置構件在其邊緣處使幅材顫動而與該等對置構件接觸之機會較少。 It has been found that where the web comes from or is passed to a liquid-free area, in either of these scenarios, there are no two liquids present that need to be isolated from each other, incorporating the grooves into The opposing surfaces may allow the web to flutter into contact with the opposing members. In such cases, it is preferable to use a notched air knife or the notched side of the air knife. The slotted opposing members have less chance of fluttering the web at their edges to come into contact with the opposing members.

如較佳地，在經由狹縫將空氣供應至氣刀中之情況下，空氣沿著幅材在兩側上在幅材移動之上游及下游行進。對於幅材之對稱軸承支撐，該等對置表面之間的間隙(小於幅材之厚度)實質上等於供應空氣之 狹縫的寬度。此行進至幅材且接著在幅材之各側上分成兩個，且在此情況下僅需要截面流動區域之一半來維持類似流動條件。此藉由在幅材之相對側上可用的相同大小間隙之一半來提供。 As preferably, where air is supplied into the air knife through the slit, the air travels upstream and downstream of the web movement on both sides along the web. For symmetrical bearing support of the web, the gap between the opposing surfaces (less than the thickness of the web) is substantially equal to the supply air The width of the slit. This travels to the web and then splits into two on each side of the web, and in this case only one half of the cross-sectional flow area is required to maintain similar flow conditions. This is provided by one half of the same size gap available on opposite sides of the web.

不管液體在凹槽外部抑制幅材之橫向移動的傾向，儘管如此，在凹槽外部的對置表面區域較佳地大於在內部區域。 Regardless of the tendency of the liquid to inhibit transverse movement of the web outside the groove, the opposing surface area outside the groove is preferably greater than the interior area, nonetheless.

在分別在上游或下游提供有凹槽配置且在下游或上游提供有槽口配置之情況下，自狹縫至凹槽及自狹縫至槽口的區域之長度較佳地大體上相同，藉此幅材之軸承支撐在上游及下游係類似的，無幅材觸碰該等對置表面之傾向。 Where a groove arrangement is provided upstream or downstream and a notch arrangement is provided downstream or upstream, respectively, the lengths of the areas from slit to groove and from slit to notch are preferably substantially the same, whereby The bearing support of the web is similar upstream and downstream, with no tendency for the web to touch the opposing surfaces.

相比於將氣刀用於焊料整平之先前使用，在空氣狹縫交錯以自一個方向及接著自另一方向清除焊料(詳言之，自穿過鍍錫板中之通孔)之情況下，在液體隔離氣刀中，較佳將空氣狹縫以彼此對置之方式置放，以使得該等空氣狹縫用來使幅材在該等對置表面之間居中。 In contrast to previous use of air knives for solder leveling, where air slits are staggered to remove solder from one direction and then the other (specifically, from through holes in tinplates) Next, in liquid-isolated air knives, the air slits are preferably placed opposite each other so that the air slits serve to center the web between the opposing surfaces.

儘管已在上文給出凹槽及槽口之替代方案，但實際上關於液體移除裝置之其他特徵，狹縫或孔隙線之布建可具有替代方案。詳言之，一個或各對置表面可具有兩個或甚至更多個狹縫或孔隙線。宜將平面表面部分設置於狹縫或孔隙線之間，藉此將來自各別狹縫/孔隙線之氣流分別向外導引，以確保上游及下游之均勻氣流。凹槽/槽口係設置在兩個狹縫/孔隙線外。替代地或另外地，設置於狹縫之間的平面表面部分彼此平均間隔。 Although alternatives to grooves and notches have been given above, in practice the arrangement of slits or aperture lines may have alternatives with regard to other features of the liquid removal device. In particular, one or each opposing surface may have two or even more slits or aperture lines. Planar surface portions are preferably provided between the slits or aperture lines, whereby the airflow from the respective slit/aperture line is directed outwards, respectively, to ensure uniform airflow upstream and downstream. The grooves/notches are provided outside the two slit/aperture lines. Alternatively or additionally, the planar surface portions disposed between the slits are evenly spaced from each other.

該等對置構件可各自由三個部件組成，該等部件在接合面處互補地切削且固定在一起以提供該等對置構件中之一者，●具有該等部件之一平面中心部件及該等部件之兩個有凹槽或有槽 口部件，該等部件在其接合處經切削以在該中心部件與有凹槽或有槽口部件中之一者之間提供一個該狹縫，及在該中心部件與有凹槽或有槽口部件中之另一者之間提供另一個該狹縫，且●該中心部件在該等狹縫之間與該等其他部件齊平。 The opposing members may each consist of three parts that are complementarily cut at the joints and fixed together to provide one of the opposing members, a planar central part having one of the parts and Both of these parts are grooved or grooved Mouth pieces that are cut at their junctures to provide one of the slits between the center piece and one of the fluted or slotted pieces, and between the centre piece and the fluted or slotted pieces Another of the slits is provided between the other of the mouth pieces, and • the central piece is flush with the other pieces between the slits.

為幫助理解本發明，現將藉助於實例且參考附圖來描述本發明之特定具體實例，其中：圖1為根據本發明的包括氣刀之幅材處理裝置之截面側視圖；圖2為裝置之沖洗儲槽的更大比例之類似視圖，在沖洗儲槽之上游及下游有氣刀；圖3再次為下游氣刀之更大比例的類似視圖；圖4為氣刀中之一者本身的透視截面圖；圖5為根據本發明之繪示凹槽的圖4之氣刀的局部視圖；圖6為併有本發明之液體移除裝置的處理浴槽及清洗儲槽之另一具體實例的截面圖； 圖7為包括於圖6之具體實例中的液體移除及隔離氣刀之局部視圖；圖8為組合式氣刀及液體軸承之類似視圖；圖9為包括本發明之氣刀的清洗台之水平配置的類似於圖6之視圖；圖10為另一變化形式氣刀的類似於圖4之視圖；且圖11為另一變化形式氣刀的類似於圖8之視圖。 To aid in the understanding of the invention, specific embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which: Figure 1 is a cross-sectional side view of a web processing apparatus including an air knife according to the present invention; Figure 2 is the apparatus A similar view on a larger scale of the flush tank with air knives upstream and downstream of the flush tank; Figure 3 is again a similar view on a larger scale of the downstream air knife; Figure 4 is a view of one of the air knives itself perspective cross-sectional view; FIG. 5 is a partial view of the air knife of FIG. 4 showing grooves according to the present invention; Sectional view; Fig. 7 is a partial view of the liquid removal and isolation air knife included in the embodiment of Fig. 6; Fig. 8 is a similar view of a combined air knife and liquid bearing; Fig. 9 is a view of a cleaning station including the air knife of the present invention Figure 10 is a view similar to Figure 4 of another variant air knife; and Figure 11 is a view similar to Figure 8 of another variant air knife.

參考圖式，幅材處理裝置1具有兩個處理儲槽2、3，各自具有各別上部軸承流體軸承21、31及下部軸承流體軸承22、32。在使用中，幅材4圍繞該等軸承蜿蜒地通過，以在儲槽2中用化學溶液23處理及在儲槽3中用水33沖洗。各別氣刀5、6設置於自儲槽2之出口/至儲槽3之進口處及自儲槽3之出口處。儘管定向不同，但該等氣刀實質上相同，且將詳細描述僅一個氣刀。幅材4圍繞複數個其他流體軸承10傳遞，該等流體軸承導引該幅材4進出該等槽。 Referring to the figures, the web processing apparatus 1 has two processing tanks 2, 3, each with a respective upper bearing fluid bearing 21, 31 and a lower bearing fluid bearing 22, 32, respectively. In use, the web 4 is meandered around the bearings for treatment with chemical solution 23 in tank 2 and flushing with water 33 in tank 3 . The respective air knives 5 and 6 are arranged at the outlet from the storage tank 2 / the inlet to the storage tank 3 and the outlet from the storage tank 3 . Although oriented differently, the air knives are substantially the same and only one will be described in detail. The web 4 is passed around a plurality of other fluid bearings 10 which guide the web 4 in and out of the slots.

各氣刀由四個部件組成：固定在一起作為下部構件7的上游部件71及下游部件72，及固定在一起作為上部構件8的類似部件81、82。該等上游部件71、81具有平面配合面73、83；而該等下游部件72、82具有切削面74、84，該等切削面提供空氣供應充氣室75、85、空氣供應槽76、86、內部充氣室77、87及氣刀狹縫78、88。提供用於將空氣供應至該等充氣室75、85之未繪示構件，藉此延伸空氣噴流朝向彼此退出該等狹縫78、88。空氣噴流在幅材處於該等氣刀構件之間時沖射於該幅材上。 Each air knife consists of four parts: an upstream part 71 and a downstream part 72 fixed together as the lower member 7 , and similar parts 81 , 82 fixed together as the upper member 8 . The upstream parts 71, 81 have planar mating surfaces 73, 83; and the downstream parts 72, 82 have cutting surfaces 74, 84 that provide air supply plenums 75, 85, air supply grooves 76, 86, Internal plenums 77, 87 and air knife slits 78, 88. Means not shown are provided for supplying air to the plenums 75, 85 whereby the extended air jets exit the slits 78, 88 towards each other. Air jets impinge on the web as it is between the air knife members.

自該等狹縫，該空氣沿著該幅材之頂部及底部的面41、42流動。在不存在凹槽9之情況下，如正根據本發明將描述，氣流在上游及 下游方向中退出該氣刀，自該等刀構件之對置面79、89之間離開。在此情況下，空氣吹掉傾向於吸入於該等構件之間的任何液滴。 From the slits, the air flows along the top and bottom faces 41, 42 of the web. In the absence of grooves 9, as will be described in accordance with the present invention, the gas flow is upstream and The air knife is withdrawn in the downstream direction, away from between the opposing surfaces 79, 89 of the knife members. In this case, the air blows away any droplets that tend to be drawn between the components.

原先期望氣刀對幅材進行有充分的乾燥效果。然而，已經歷過看起來起因於凹槽9不存在之情況下的不均勻乾燥的效果。 The air knife was originally expected to have a sufficient drying effect on the web. However, effects that appear to result from uneven drying in the absence of grooves 9 have been experienced.

凹槽包含對置面79、89中之上游對置半圓形凹槽91及下游對置半圓形凹槽92。咸信該等凹槽作為在其外部徹底等化空氣在幅材4之面41、42上之壓力及流動的充氣室而操作。 The grooves include an upstream opposed semicircular groove 91 and a downstream opposed semicircular groove 92 in the opposed surfaces 79 , 89 . It is believed that these grooves operate as plenums that completely equalize the pressure and flow of air on the faces 41 , 42 of the web 4 outside them.

此外，對置面在凹槽外略微地解開，其中對置面之分離101大於其在凹槽內之分離102。因此，流動不僅變得均勻，而且亦減慢。再次，此為出人意料但有效的。 Furthermore, the opposing faces are slightly unwound outside the groove, wherein the separation 101 of the opposing faces is greater than their separation 102 inside the groove. Therefore, the flow not only becomes uniform, but also slows down. Again, this is unexpected but effective.

現轉而參看圖6至圖8，另一幅材處理裝置具有處理儲槽202，其中進口空氣軸承210在其表面上方具有空氣噴嘴211之陣列，其導引幅材204越過空氣噴嘴至處理儲槽中。為軸承供應加壓為略高於大氣壓力之經過濾空氣。可將空氣處理成稱為CDA空氣(Clean,Dry Compressed Air；清潔、乾燥、壓縮空氣)之標準。空氣自產生空氣軸承層之噴嘴發出，從而使得幅材能夠在軸承上方經過而不與其接觸。 Turning now to Figures 6-8, another web processing apparatus has a processing reservoir 202 with an inlet air bearing 210 having an array of air nozzles 211 above its surface that guide the web 204 past the air nozzles to the processing reservoir in the slot. Supply the bearing with filtered air pressurized slightly above atmospheric pressure. The air can be treated to a standard called CDA air (Clean, Dry Compressed Air; clean, dry, compressed air). Air is emitted from the nozzles that create the air bearing layer, allowing the web to pass over the bearing without contacting it.

儲槽具有各別上部液體承載軸承221及下部液體承載軸承222。為此等軸承供應液體223，在儲槽中經由類似噴嘴(圖中未示)以液體223對幅材進行處理，所供應液體負壓且產生軸承薄膜以供幅材沿著圍繞軸承之蛇形路徑通過，而不觸碰軸承。 The sump has respective upper 221 and lower 222 fluid-carrying bearings. To this end the bearings are supplied with liquid 223, the web is treated with the liquid 223 in a tank via similar nozzles (not shown), the liquid is supplied under negative pressure and a bearing film is created for the web to follow the serpentine around the bearing The path passes without touching the bearing.

自處理儲槽垂直地離開，幅材204傳遞至液體隔離氣刀206。相比於上述氣刀6，在氣刀狹縫2061上方與下方之氣刀配置不同。在 狹縫上方，氣刀之對置構件2062在其對置面20641、20642中具有對置凹槽2063。凹槽用來穩定CDA空氣之向上流動，使得存在於氣刀上方之清洗液體233並不穿透於氣刀之對置構件2062之間。在狹縫下方，對置表面解開，形成槽口2065。此等槽口朝下打開，使得幅材上自儲槽抽取出之任何處理液體由自槽口發出之空氣吹回，且若任何液體進入槽口中，則該液體在空氣自狹縫下方之對置面2064的未解開帶2066之間的狹窄氣隙發出時由空氣吹回。 Exiting vertically from the processing tank, the web 204 is passed to a liquid-isolated air knife 206 . Compared with the above-mentioned air knife 6, the air knives above and below the air knife slit 2061 are arranged differently. exist Above the slit, the opposing member 2062 of the air knife has opposing grooves 2063 in its opposing surfaces 20641, 20642. The grooves serve to stabilize the upward flow of the CDA air so that the cleaning liquid 233 present above the air knife does not penetrate between the opposing members 2062 of the air knife. Below the slits, the opposing surfaces unravel, forming notches 2065. These slots open downwards so that any process liquid drawn from the reservoir on the web is blown back by the air emanating from the slots, and if any liquid enters the slots, it is blown back against the air from below the slits The narrow air gap between the unreeled straps 2066 of the placement surface 2064 is blown back by air as it emerges.

已發現在幅材厚0.1mm之情況下將空氣供應至狹縫及0.5bar下令人滿意之典型尺寸為：狹縫2061之寬度 0.1mm Typical dimensions that have been found to be satisfactory for supplying air to the slit with a web thickness of 0.1 mm and at 0.5 bar are: Width of slit 2061 0.1 mm

對置面20641處的間隙 0.2mm至0.3mm Gap at the opposing surface 20641 0.2mm to 0.3mm

對置面20642處的間隙 0.4mm The gap at the opposite surface 20642 is 0.4mm

凹槽2063之直徑 5mm Diameter of groove 2063 5mm

面20641處狹縫至凹槽 1.5mm Slit to groove 1.5mm at face 20641

面20642處之凹槽至倒角 5.5mm Groove at face 20642 to chamfer 5.5mm

面2066處之狹縫至槽口 2.5mm Slit at face 2066 to notch 2.5mm

就此等尺寸為有效的而言，期望各別尺寸減半至倍增亦將為有效的。 For these dimensions to be effective, it is expected that halving to doubling the respective dimensions will also be effective.

在氣刀206之一側上方及至一側，在清洗儲槽203之上游設置兩個清洗液體轉移軸承2031。清洗液體233，典型地為去離子水，經抽汲至該等軸承，從而在軸承上方形成軸承薄膜。液體中之一些沿著幅材向下回流至氣刀206，在該處液體圍繞幅材之邊緣流動以開始沖洗幅材之另一側。 Above and to one side of the air knife 206, two cleaning liquid transfer bearings 2031 are provided upstream of the cleaning reservoir 203. A cleaning liquid 233, typically deionized water, is pumped to the bearings, thereby forming a bearing film over the bearings. Some of the liquid flows back down the web to the air knife 206 where it flows around the edge of the web to begin flushing the other side of the web.

自轉移軸承，幅材傳遞至清洗儲槽203之第一部分2032中。在此，幅材圍繞配備有清洗液體之另一軸承2034傳遞，該軸承在儲槽中之清洗水的正常深度2036上方。因此，幅材向上傳遞至複合式軸承及氣刀207。此氣刀具有軸承汽缸2071，其內部地劃分成兩個清洗液體通道20721、20722，其間具有中心空氣通道2073。各通道具有軸承噴嘴2074。在汽缸2071上方配置有具有中心氣刀狹縫2076及上游及下游槽口2077的氣刀對置構件2075。 The web is transferred into the first part 2032 of the cleaning tank 203 from the transfer bearing. Here, the web is passed around another bearing 2034 equipped with washing liquid above the normal depth 2036 of the washing water in the sump. Thus, the web is passed up to the composite bearing and air knife 207 . This air knife has a bearing cylinder 2071 which is internally divided into two cleaning liquid channels 20721, 20722 with a central air channel 2073 in between. Each channel has a bearing nozzle 2074. Above the cylinder 2071, an air knife opposing member 2075 having a central air knife slit 2076 and upstream and downstream notches 2077 is arranged.

在幅材越過軸承汽缸且空氣供應至狹縫2076及中心通道且清洗液體供應至通道20721、20722之情況下，氣流隔離清洗儲槽203之各別部分2032、2033的清洗液體。在上游槽口2077處吹回由幅材向上攜載至汽缸2071上之幅材的頂部之任何清洗液體。同等地，儘管相同液體經抽汲至上游通道20721且經由其噴嘴出，但來自中心通道2073之空氣將此液體吹回，防止其通過狹縫2074。 With the web passing over the bearing cylinders and air being supplied to the slot 2076 and central channel and cleaning liquid being supplied to the channels 20721, 20722, the air flow isolates the cleaning liquid of the respective portions 2032, 2033 of the cleaning tank 203. Any cleaning liquid carried up by the web to the top of the web on the cylinder 2071 is blown back at the upstream slot 2077 . Equally, although the same liquid is pumped to the upstream channel 20721 and out through its nozzle, air from the central channel 2073 blows this liquid back, preventing it from passing through the slit 2074.

儘管可將相同清洗液體抽汲至通道20722，但亦可在複合式軸承及氣刀207中及實際上在清洗儲槽之第二部分2033中將此保持為單獨的，從而改良沖洗。以類似方式，來自中心通道之空氣傾向於吹回來自第二通道20722之任何液體，液體可傾向於經過中心空氣噴嘴2074流動返回。來自通道20722及其噴嘴2074之軸承液體傳遞至第二儲槽部分2033中。 Although the same cleaning liquid can be pumped to the channel 20722, this can also be kept separate in the composite bearing and air knife 207 and indeed in the second portion 2033 of the cleaning tank, improving flushing. In a similar manner, air from the central channel tends to blow back any liquid from the second channel 20722, which may tend to flow back through the central air nozzle 2074. The bearing fluid from the channel 20722 and its nozzle 2074 is transferred into the second sump portion 2033.

在此儲槽部分中，幅材圍繞另一濕式軸承2037傳遞且直至氣刀208。應注意，沖洗發生在軸承處，其中與浸沒於儲槽部分2032、2033中之液體中相反，清洗液體相對於幅材作為流體動力軸承薄膜流動。 In this sump section, the web is passed around another wet bearing 2037 and up to the air knife 208 . It should be noted that flushing occurs at the bearings, where the cleaning liquid flows relative to the web as a hydrodynamic bearing film, as opposed to being submerged in the liquid in the sump portions 2032, 2033.

氣刀208具有類似於槽口2065之上部及下部槽口2081。因 此，幅材傳遞至空氣軸承209及至後續處理台上或至繞動台(兩者均未繪示)。 Air knife 208 has upper and lower notches 2081 similar to notches 2065. because Here, the web is transferred to an air bearing 209 and onto a subsequent processing station or to an orbiting station (neither of which are shown).

轉而參看圖9，可使用流體隔離氣刀當正在處理之幅材或板水平地以及按上文所描述之各種角度行進。圖9繪示一對沖洗台(301、302)，諸如英國專利第2,459,055號中所繪示，沖洗台各自具有上部及下部、上游及下游的流徑界定板3011、3012、3013、3014、；3021、3022、3023、3024，其具有雙交錯清洗液體狹縫3015、3025。幅材304在板與噴口之間通過。氣刀305、306、307配置在沖洗台之上游與下游之間。 9, the fluid isolation air knife can be used when the web or board being processed is traveling horizontally and at various angles as described above. Figure 9 shows a pair of flushing stations (301, 302), such as shown in UK Patent No. 2,459,055, each having upper and lower, upstream and downstream flow path defining plates 3011, 3012, 3013, 3014,; 3021, 3022, 3023, 3024 with double staggered cleaning liquid slits 3015, 3025. The web 304 passes between the plate and the spout. Air knives 305, 306, 307 are disposed upstream and downstream of the wash station.

台301與302之間的氣刀306具有在其對置構件中之凹槽3061、3062，及倒角上游及下游邊緣3063。配置如此以使得清洗台板之邊緣接近氣刀構件，使得清洗液體流動至頂部板之頂部上且保持以免自幅材底下自由地流動，藉此儘可能長時間地將幅材曝露於清洗液體。因此，氣刀之倒角使清洗液體在倒角與幅材之間。儘管如此，自倒角開始之凹槽有效地自對置構件之間提供均勻氣流，藉此液體不流入氣刀而流經倒角。 The air knife 306 between the tables 301 and 302 has grooves 3061, 3062 in its opposing members, and chamfered upstream and downstream edges 3063. The configuration is such that the edge of the cleaning platen is proximate the air knife member so that the cleaning liquid flows onto the top of the top plate and is kept from flowing freely from under the web, thereby exposing the web to the cleaning liquid for as long as possible. Therefore, the chamfer of the air knife keeps the cleaning liquid between the chamfer and the web. Nonetheless, the grooves starting from the chamfer effectively provide a uniform airflow from between the opposing members, whereby the liquid does not flow into the air knife and flows through the chamfer.

氣刀305、307在其面朝清洗台板之側處具有類似凹槽。在外側處，氣刀具有槽口，諸如槽口2065、2077、2081。槽口與中心氣刀狹縫之間的區域如凹槽與氣刀狹縫之間，藉此將來自狹縫之氣流分為上游及下游流動。 The air knives 305, 307 have similar grooves on their side facing the wash platen. At the outside, the air knife has notches, such as notches 2065, 2077, 2081. The area between the notch and the central air knife slit, such as between the groove and the air knife slit, thereby divides the gas flow from the slit into upstream and downstream flows.

在圖10及圖11中繪示兩個另外變化形式。相對於圖4中所示之兩部件構造，圖10之氣刀17具有三部件構造。在對此變化形式之描述中，並不單獨地描述上部部件及下部部件，此係因為該等部件實際上彼此相同。除了彼此為鏡像外，具有凹槽192之外部部件171、172係相同，此 係因為各部件具有提供空氣供應充氣室175、空氣供應槽176、內部充氣室177及氣刀狹縫178之切削面174。此等外部部件緊靠平面最內部件190。因此，提供兩個氣刀狹縫，供應有相同空氣。最內部件及外部部件跨狹縫齊平，且最內部件在幅材通道處為平面的。就無空氣可自狹縫朝內流動而言，流動朝外，期望在上游及下游方向兩者中有接近類似之流動。狹縫之間的間距必須顯著地寬於外部空氣軸承表面，則可提供凹槽(或槽口)以防止最內部件與幅材之間的接觸。 Two further variants are depicted in FIGS. 10 and 11 . As opposed to the two-part configuration shown in FIG. 4, the air knife 17 of FIG. 10 has a three-part configuration. In the description of this variant, the upper part and the lower part are not described separately, since these parts are practically identical to each other. The outer parts 171, 172 with the grooves 192 are identical except that they are mirror images of each other, this This is because each component has a cutting face 174 that provides an air supply plenum 175 , an air supply slot 176 , an inner plenum 177 and an air knife slit 178 . These outer parts abut the planar innermost part 190 . Therefore, two air knife slits are provided, supplied with the same air. The innermost part and the outer part are flush across the slit, and the innermost part is planar at the web channel. To the extent that no air can flow inward from the slit, the flow is outward, and a near-similar flow is expected in both the upstream and downstream directions. The spacing between the slits must be significantly wider than the outer air bearing surface, grooves (or notches) may be provided to prevent contact between the innermost component and the web.
