Description
本發明是有關於用於捕集被過濾氣體中所含有的粒子的過濾器濾材之製造裝置,特別是有關於製造使形成片狀之濾材胚料經打褶加工而成之過濾器濾材者。 The present invention relates to a device for producing a filter medium for trapping particles contained in a filter gas, and more particularly to a filter medium for producing a sheet-shaped filter material billet which is pleated.
以往在製造半導體和液晶之工廠的無塵室(clean room)等,會使用構成為可捕集被過濾氣體中所含有的粒子之過濾器濾材。這種過濾器濾材是使用使形成片狀之濾材胚料在複數個位置彎曲以形成皺褶狀者。此種過濾器濾材包含,使濾材胚料彎曲所形成的彎曲部和,可將該彎曲部以外的區域配置成相面對而形成的複數個平板部和,用於保持相鄰平板部彼此之間隔的複數個間隔保持部。 In the clean room or the like of a factory for manufacturing semiconductors and liquid crystals, a filter medium configured to trap particles contained in the filtered gas is used. Such a filter medium is formed by bending a billet-shaped filter material billet at a plurality of positions to form a wrinkle shape. Such a filter medium includes a curved portion formed by bending a filter material blank, and a plurality of flat portions formed by facing the curved portion and facing each other for holding adjacent flat portions A plurality of interval holding portions spaced apart.
製造此種過濾器濾材之製造裝置可使用設有打褶加工部、黏著劑塗布部及濾材形成部者,前述打褶加工部係構成為使片狀之濾材胚料一邊沿一個方向被搬送一邊在複數個位置彎曲(作打褶加工)以形成皺褶狀,前述黏著劑 塗布部係對經該打褶加工部進行打褶加工之濾材胚料塗布黏著劑,前述濾材形成部係使經該黏著劑塗布部塗布黏著劑之濾材胚料再次形成皺褶狀以形成過濾器濾材(參照專利文獻1以及2)。 In the manufacturing apparatus for producing such a filter medium, a pleated portion, an adhesive application portion, and a filter material forming portion are provided, and the pleated portion is configured to convey the sheet-shaped filter material in one direction. Bending (pleating) at a plurality of positions to form a wrinkle shape, the aforementioned adhesive The coating unit applies an adhesive to the filter material blank which is pleated by the pleated portion, and the filter material forming portion re-forms the filter material blank coated with the adhesive through the adhesive application portion to form a filter. Filter medium (refer to Patent Documents 1 and 2).
如上述之製造裝置,藉由在打褶加工部形成彎曲部,可對濾材胚料上成為彎曲部之區域賦予折痕特性。因此,在黏著劑塗布部將黏著劑塗布至濾材胚料時,即使濾材胚料之形成皺褶狀的區域(以下,亦記載為皺褶狀區域)被拉伸展開,也變得可以容易地在濾材形成部回復成皺褶狀。 According to the manufacturing apparatus described above, by forming the curved portion in the pleated portion, it is possible to impart crease characteristics to the region of the filter blank which is the curved portion. Therefore, when the adhesive is applied to the filter blank in the adhesive application portion, even if the wrinkle-forming region (hereinafter referred to as a wrinkle region) of the filter blank is stretched and unwound, it becomes easy to The filter medium forming portion returns to a wrinkle shape.
為了良好地保持此種折痕特性,而提出還設有使濾材胚料之皺褶狀區域沿一個方向壓縮之打褶壓縮部的製造裝置之方案。該打褶壓縮部,由於可壓縮皺褶狀區域以使平板部彼此之間隔相接近,故可強化濾材胚料之折痕特性。藉此,即使皺褶狀區域從受到壓縮的狀態展開時,仍能良好地維持濾材胚料之折痕性狀。 In order to maintain such crease characteristics well, it is proposed to provide a manufacturing apparatus for a pleated compression portion that compresses the crease-like region of the filter material blank in one direction. In the pleated compression portion, since the pleated regions can be compressed so that the flat portions are spaced apart from each other, the crease characteristics of the filter material can be enhanced. Thereby, even if the wrinkle-like region is unfolded from the compressed state, the crease property of the filter material blank can be favorably maintained.
然而,在如上述之製造裝置中,因濾材胚料和製造裝置會滑動接觸,而有使濾材胚料帶電之虞。並且,當使濾材胚料之皺褶狀區域在打褶壓縮部以受到壓縮的狀態帶電,並使皺褶狀區域從受到壓縮的狀態展開時,會有平板部彼此之間隔變寬而在相鄰的平板部之間放電的情形。此類放電,變成在平板部形成貫通孔的主要原因,並會因為形成此種貫通孔,造成過濾器濾材之集塵效率下降。 However, in the manufacturing apparatus as described above, since the filter material blank and the manufacturing apparatus are in sliding contact, there is a possibility that the filter material is charged. Further, when the wrinkle-like region of the filter material blank is charged in a state where the pleated compression portion is compressed, and the crease-like region is unfolded from the compressed state, the interval between the flat plate portions is widened and the phase is widened. A situation in which the adjacent flat portions are discharged. Such discharge becomes a factor that forms a through hole in the flat plate portion, and the dust collecting efficiency of the filter medium is lowered due to the formation of such a through hole.

專利文獻2:日本專利特開2004-321937號公報 Patent Document 2: Japanese Patent Laid-Open Publication No. 2004-321937
因此,本發明之課題在於提供一種過濾器濾材之製造裝置,其可在平板部彼此之間隔變寬時防止相鄰平板部之間發生放電,並可抑制因為此種放電在濾材胚料形成貫通孔而導致過濾器濾材之集塵效率下降。 Accordingly, an object of the present invention is to provide a filter medium manufacturing apparatus which can prevent discharge between adjacent flat plate portions when the interval between the flat plate portions is widened, and can suppress formation of a blank in the filter material due to such discharge. The pores cause a decrease in the dust collecting efficiency of the filter medium.
本發明的過濾器濾材之製造裝置,包含:打褶加工部,藉由在片狀濾材胚料之一個方向上複數個位置沿垂直相交於一個方向之另一個方向彎曲濾材胚料以形成複數個彎曲部,同時使該等彎曲部以外的區域配置成相面對以形成複數個平板部,而使濾材胚料形成皺褶狀;打褶壓縮部,使濾材胚料中形成皺褶狀之區域一邊沿一個方向搬送一邊沿一個方向壓縮以使平板部彼此之間隔相接近;除電部,在該打褶壓縮部之位於濾材胚料搬送方向下游側之端部對濾材胚料放出離子以執行濾材胚料之消除靜電;及打褶展開部,使該濾材胚料中受到打褶壓縮部壓縮的區域從受到壓縮的狀態展開以使平板部彼此之間隔相較於在打褶壓縮部時變寬。 The apparatus for manufacturing a filter medium according to the present invention comprises: a pleating unit that bends a filter material billet in a direction intersecting perpendicularly in one direction in a plurality of positions in one direction of the sheet-shaped filter material to form a plurality of The curved portion is configured such that the regions other than the curved portions are disposed to face each other to form a plurality of flat plate portions, and the filter material blank is formed into a wrinkle shape; the pleated compression portion is formed to form a wrinkled region in the filter material blank Compressing in one direction while compressing in one direction to bring the flat plate portions closer to each other; the static eliminating portion discharges ions to the filter material blank at the end portion of the pleated compression portion on the downstream side in the filter material conveying direction to execute the filter material The static elimination of the billet; and the pleating development portion expands the region of the filter material billet compressed by the pleated compression portion from the compressed state so that the interval between the flat plate portions is wider than when the pleated compression portion is formed .
透過此種構成,由於設有除電部,在打褶展開部使平板部彼此之間隔變寬之時,可以防止相鄰平板部之間發生放電之情形。具體而言,在打褶壓縮部之位於濾材胚料搬送方向下游側之端部處,濾材胚料中形成皺褶狀之區域(以下,亦記載為皺褶狀區域),會變成平板部彼此之間隔相接近之狀態。也就是說,由於在打褶壓縮部之位於濾材胚料搬送方向下游側的端部處,會使濾材胚料之皺褶狀區域變成帶電狀態,藉由在此端部從除電部對濾材胚料放出離子,可透過濾材胚料與離子之接觸而使濾材胚料被消除靜電。藉此,就算在打褶展開部使平板部彼此之間隔變寬時,仍然可以防止相鄰平板部之間發生放電。 According to this configuration, since the static eliminating portion is provided and the interval between the flat plate portions is widened in the pleating and expanding portion, it is possible to prevent the occurrence of discharge between the adjacent flat plate portions. Specifically, in the end portion of the pleated compression portion on the downstream side in the direction in which the filter material is conveyed, a region in which a wrinkle-like region is formed in the filter material blank (hereinafter also referred to as a wrinkle-like region) becomes a flat portion. The interval is close to the state. That is, since the wrinkle-like region of the filter material billet becomes a charged state at the end portion of the pleated compression portion on the downstream side in the direction in which the filter material is conveyed, the filter body is removed from the static electricity portion at the end portion. The material releases ions, which can pass through the contact between the filter material and the ions, so that the filter material is statically eliminated. Thereby, even when the pleating development portion widens the interval between the flat plate portions, it is possible to prevent the discharge from occurring between the adjacent flat plate portions.
前述打褶壓縮部宜設有:挾持部,係從濾材胚料的雙面側包夾濾材胚料中形成皺褶狀之區域;及加壓部,係相較於該挾持部配置於濾材胚料搬送方向之下游側,用以至少從濾材胚料其中一面側對濾材胚料中形成皺褶狀之區域加壓;且,前述除電部宜構成為可在加壓部之位於濾材胚料搬送方向下游側之端部對濾材胚料放出離子。 Preferably, the pleating and compressing portion is provided with a gripping portion that forms a wrinkle-like region from the double-sided side of the filter material blank, and a pressurizing portion that is disposed on the filter embryo than the grip portion a downstream side of the material conveying direction for pressurizing at least one side of the filter material blank to form a wrinkle-like region in the filter material blank; and the static electricity removing portion is preferably configured to be transported in the filter material at the pressurizing portion The end portion on the downstream side of the direction discharges ions to the filter material blank.
透過此種構造,使濾材胚料的皺褶狀區域以受到挾持部包夾之狀態搬送,同時以受加壓部加壓之狀態搬送,故會因挾持部以及加壓部的滑動接觸而容易帶電。然而,由於是在加壓部之濾材胚料搬送方向下游側之端部從除電部對濾材胚料放出離子,故可在進入打褶展開部前(亦即,相鄰平板部間不發生放電之狀態下)使濾材胚料被消除靜電。藉此,就算在打褶展開部使平板部彼此之間隔變寬 時,仍然可以防止相鄰平板部之間發生放電。 With this configuration, the wrinkle-like region of the filter material is conveyed in a state of being sandwiched by the gripping portion, and is conveyed while being pressurized by the pressurizing portion, so that it is easy to slide by the grip portion and the pressurizing portion. charged. However, since the ions are discharged from the static electricity removing portion to the filter material billet at the end portion on the downstream side in the filter material billet conveying direction of the pressurizing portion, it is possible to enter the pleating development portion (that is, no discharge occurs between the adjacent flat plate portions). In the state of the filter material, the filter material is statically removed. Thereby, even if the pleating expansion portion widens the interval between the flat portions At the same time, it is still possible to prevent discharge from occurring between adjacent flat plate portions.
前述除電部宜構成為從濾材胚料其中一面側朝濾材胚料之搬送方向上游側放出離子。 Preferably, the static eliminating portion is configured to emit ions from one side of the filter material blank toward the upstream side in the conveying direction of the filter material.
透過此種構成,以從濾材胚料其中一面側朝濾材胚料之搬送方向上游側放出離子的方式構成除電部,藉此,使從除電部放出的離子可對濾材胚料形成有效率的接觸。藉此,可以有效率地執行濾材胚料之消除靜電,且在打褶展開部使平板部彼此之間隔變寬時,也可以更有效地防止相鄰平板部之間發生放電。 According to this configuration, the electricity removing unit is configured to discharge ions from one side of the filter material to the upstream side in the conveying direction of the filter material, whereby the ions discharged from the static eliminating unit can efficiently contact the filter material. . Thereby, it is possible to efficiently perform the static elimination of the filter material blank, and it is possible to more effectively prevent the discharge between the adjacent flat plate portions when the pleating development portion widens the interval between the flat plate portions.
如以上所述,透過本發明,可在平板部彼此之間隔變寬時,防止相鄰平板部之間發生放電,並可抑制因為此種放電在濾材胚料形成貫通孔而導致過濾器濾材之集塵效率下降。 As described above, according to the present invention, when the interval between the flat plate portions is widened, the discharge between the adjacent flat plate portions can be prevented, and the filter medium can be prevented from being formed in the filter material blank by the through holes. Dust collection efficiency is reduced.

The porous sheet body is not particularly limited, and may be appropriately selected depending on the use of the filter medium F1. For example, a sheet of PTFE sheet, a melt-blown nonwoven fabric, an electret filter, or a glass fiber can be used. In the present embodiment, a PTFE sheet is used as the porous sheet. The pressure loss of the PTFE sheet at a penetration flow rate of 5.3 cm/sec is preferably 50 mmH 2 O or less. In addition, it is preferable that the PTFE sheet has a collection efficiency (calculated as in the following examples) at a flow rate of 5.3 cm/sec and a particle diameter of 0.1 μm or more and 0.2 μm or less, which is 80% or more. The ratio is preferably 99.9% or more, and the PF value is preferably 22 or more.

Further, the pleated portion 2 is provided with a pair of blade-shaped blades 2a and 2a formed in a plate shape. Further, the pleating processing unit 2 is configured to convey the filter material blank A between the pair of blade plates 2a and 2a. Moreover, the pair of blades 2a and 2a are arranged in the other direction (width direction) perpendicularly intersecting one direction (longitudinal direction) of the filter blank A. Further, the filter material blank A when being conveyed to the pleating portion 2 should be cut to a predetermined width.
並且,可藉由使一對刀板2a、2a分別沿軌道2L 作動,以對濾材胚料A作打褶加工。具體而言,是以其中一方的刀板2a使濾材胚料A從其中一面側朝另一面側沿寬度方向彎曲,同時沿濾材胚料A之長度方向在與經其中一方之刀板2a彎曲之區域間隔相距的位置,透過另一方之刀板2a使濾材胚料A從另一面側朝其中一面側沿寬度方向彎曲。亦即,打褶加工部2構成為(往復式),透過一對刀板2a、2a,使濾材胚料A朝向長度方向以間隔隔開並交互地被折入(打褶加工)。藉此,在片狀濾材胚料A之一個方向(長度方向)上複數個位置沿另一個方向(寬度方向)使濾材胚料A彎曲以形成複數個彎曲部F1a,同時使該等彎曲部F1a以外之區域配置成相面對以形成複數個平板部F1b,因而在片狀之濾材胚料A中形成呈皺褶狀之區域(以下,亦記載為皺褶狀區域)。 And, by making the pair of blades 2a, 2a respectively along the track 2L Actuate to pleat the filter blank A. Specifically, the blade blank 2a is bent in the width direction from one side to the other side by the blade 2a, and is bent along the longitudinal direction of the filter blank A with the blade 2a passing through one of the blades 2a. The position of the regions is spaced apart, and the filter blank A is bent in the width direction from the other side toward the one side by the other blade 2a. In other words, the pleated portion 2 is configured to be reciprocating, and the filter blanks A are passed through the pair of blades 2a and 2a so as to be spaced apart from each other in the longitudinal direction and alternately folded (folded). Thereby, the filter material blank A is bent in the other direction (width direction) in one direction (length direction) of the sheet-shaped filter material blank A to form a plurality of curved portions F1a, and the curved portions F1a are simultaneously formed. The other regions are arranged to face each other to form a plurality of flat plate portions F1b, and thus a wrinkle-like region (hereinafter also referred to as a wrinkle-like region) is formed in the sheet-shaped filter material blank A.
濾材胚料A之皺褶狀區域將被搬送至打褶壓縮部5。打褶壓縮部5構成為使濾材胚料A之皺褶狀區域一邊沿一個方向(相當於片狀濾材胚料A之一個方向之方向,即,長度方向)被搬送一邊沿一個方向被壓縮。具體而言,打褶壓縮部5設有挾持部5a及加壓部5b,前述挾持部5a係從濾材胚料A之雙面側包夾濾材胚料A之皺褶狀區域,前述加壓部5b係相較於該挾持部5a配置於濾材胚料A之搬送方向下游側並至少從濾材胚料A其中一面側對濾材胚料A之皺褶狀區域加壓。 The corrugated region of the filter material blank A is conveyed to the pleated compression portion 5. The pleated compression portion 5 is configured such that the crease-like region of the filter material blank A is compressed in one direction while being conveyed in one direction (corresponding to the direction of one direction of the sheet-shaped filter material blank A, that is, the longitudinal direction). Specifically, the pleated compression unit 5 is provided with a holding portion 5a that sandwiches the crease-like region of the filter material blank A from the double-sided side of the filter material blank A, and the pressurizing portion 5a. The 5b is placed on the downstream side in the transport direction of the filter material blank A compared to the grip portion 5a, and pressurizes the wrinkle region of the filter material blank A from at least one side of the filter material blank A.
在本實施形態中,打褶壓縮部5是由用於載置濾材胚料A之皺褶狀區域的下側板5c和,配置於該下側板5c 上方之上側板5d和,用於加壓濾材胚料A之皺褶狀區域的加壓裝置5e所構成。並且,透過下側板5c之位於搬送方向上游側之區域和上側板5d構成挾持部5a,同時透過下側板5c之位於搬送方向下游側之區域和加壓裝置5e構成加壓部5b。 In the present embodiment, the pleated compression portion 5 is a lower side plate 5c for placing a corrugated region of the filter material blank A, and is disposed on the lower side plate 5c. The upper upper side plate 5d and the pressurizing device 5e for pressurizing the corrugated region of the filter material blank A are constituted. In addition, the region of the lower side plate 5c located on the upstream side in the conveyance direction and the upper side plate 5d constitute the holding portion 5a, and the region of the lower side plate 5c on the downstream side in the conveyance direction and the pressurizing device 5e constitute the pressurizing portion 5b.

Thereby, the grip portion 5a (specifically, the lower side plate 5c and the upper side plate 5d) is brought into contact with the surface of each of the curved portions F1a on the mountain side. Then, by holding the corrugated region of the filter material blank A in one direction, the grip portion 5a (specifically, the lower side plate 5c and the upper side plate 5d) is in sliding contact with each curved portion F1a.
另一方面,加壓部5b構成為使下側板5c上所載置的濾材胚料A之皺褶狀區域承受來自上方之加壓裝置5e的加壓。如此,藉由以加壓部5b加壓濾材胚料A之皺褶狀區域,在打褶壓縮部5內的濾材胚料A之搬送速度,會變得比從打褶加工部2往打褶壓縮部5之濾材胚料A的搬送速度還慢。因此,在打褶壓縮部5內,使濾材胚料A之皺褶狀區域沿一個方向(濾材胚料A之長度方向)壓縮,變成平板部F1b彼此之間隔相接近的狀態,同時強化彎曲部F1a之折痕特性。如此,藉由強化折痕特性,即使在後述的黏著劑塗布部3使濾材胚料A之皺褶狀區域拉伸展開,也可以容易地在濾材形成部4回復成皺褶狀。再者,為了有效地保持折痕特性,較佳為使打褶壓縮部5還設有用於加溫(具體而言,加溫至80℃左右)濾材胚料之加溫機構(圖未示)。 On the other hand, the pressurizing portion 5b is configured to receive the pressurization of the pressurizing device 5e from above by the wrinkle region of the filter material blank A placed on the lower side plate 5c. By pressing the corrugated region of the filter material blank A by the pressurizing portion 5b, the transport speed of the filter material blank A in the pleated compression portion 5 is pleated from the pleated portion 2 The conveying speed of the filter material blank A of the compression unit 5 is also slow. Therefore, in the pleated compression portion 5, the crease-like region of the filter material blank A is compressed in one direction (the longitudinal direction of the filter material blank A), and the flat portion F1b is brought closer to each other, and the bending portion is strengthened. F1a crease characteristics.

Further, the static eliminating device 6 is preferably configured to discharge ions to the entire region covering the width direction of the filter material blank A. Moreover, the static eliminating device 6 is configured to discharge ions from one side of the filter material blank A toward the upstream side in the conveying direction of the filter material blank A.

濾材形成部4是使在黏著劑塗布部3塗布有黏著劑(已形成為熔合道部B)之濾材胚料A在各彎曲區域A3再度彎曲以形成皺褶狀。由於已在各彎曲區域A3中,如上述地賦予折痕特性,故容易再度彎曲,並使濾材胚料A形成皺褶狀。藉此,可使各非彎曲區域A4配置成相面對。並且,使形成於相鄰的非彎曲區域A4、A4之其中一面側熔合道部B、B彼此接合,同時也使另一面側熔合道部B彼此接合。藉此,形成如圖3所示之過濾器濾材F1。該過濾器濾材F1設有複數個使濾材胚料A彎曲而形成的彎曲部F1a,同時設 有複數個由濾材胚料A之彎曲部F1a以外的區域(非彎曲區域A4)所形成的平板部F1b。又,過濾器濾材F1設有複數個用於保持相鄰的平板部F1b、F1b彼此之間隔的間隔保持部F1c。該等間隔保持部F1c是藉由使各個其中一面側熔合道部B(或者,各個另一面側熔合道部B)彼此接合而形成。 In the filter medium forming portion 4, the filter material blank A to which the adhesive agent (formed as the fusion trajectory portion B) is applied to the adhesive application portion 3 is bent again in each curved region A3 to form a wrinkle shape. Since the crease characteristics are imparted as described above in each of the curved regions A3, it is easy to bend again, and the filter material blank A is formed into a wrinkle shape.

There are a plurality of flat plate portions F1b formed by a region other than the curved portion F1a of the filter material blank A (non-bending region A4). Further, the filter medium F1 is provided with a plurality of space holding portions F1c for maintaining the interval between the adjacent flat plate portions F1b and F1b. The spacer holding portions F1c are formed by joining the one side side fusion fused portions B (or the other other surface side fused portions B) to each other.
再者,使用熱熔膠作為構成熔合道部B之黏著劑的情況中,當軟化至熱熔膠彼此可接合的程度(開放時間內)時,宜使濾材胚料A再度形成為皺褶狀。 Further, in the case where hot melt adhesive is used as the adhesive constituting the fusion fused portion B, when the softening to the extent that the hot melt adhesives can be joined to each other (opening time), the filter blank A is preferably formed into a wrinkle shape. .

Moreover, the interval between the curved portion F1a on the side of the filter material blank A and the curved portion F1a on the other side of the filter material blank A is the height L2 of the filter medium F1.
如上述所形成之過濾器濾材F1如圖4所示設有分別位於濾材胚料A其中一面側以及另一面側的間隔保持部F1c。又,各間隔保持部F1c是沿過濾器濾材F1之高度L2方向形成直線狀。又,過濾器濾材F1其中一面側的各間隔保持部F1c以及另一面側的各間隔保持部F1c,是沿過濾器濾材F1之長度L1方向(具體而言,是在直線上)交互地排列。 As shown in FIG. 4, the filter medium F1 formed as described above is provided with a space holding portion F1c which is located on one side and the other side of the filter material blank A, respectively. Further, each of the interval holding portions F1c is formed in a straight line along the height L2 direction of the filter medium F1. Further, each of the interval holding portions F1c on one side and the interval holding portions F1c on the other side of the filter medium F1 are alternately arranged along the length L1 direction of the filter medium F1 (specifically, on a straight line).
如上述之過濾器濾材F1,可收置於構成為可收置過濾器濾材F1之框體中以當作過濾器單元使用。該框體設有用於收置過濾器濾材F1之內部空間和,與連通至該內部空間的一對開口部。藉此,框體構成為使被過濾氣體可從其中一方的開口部側向另一方的開口部側通過。 The filter medium F1 as described above can be placed in a frame which is configured to accommodate the filter medium F1 to be used as a filter unit. The frame body is provided with an inner space for accommodating the filter medium F1 and a pair of openings communicating with the inner space. Thereby, the casing is configured such that the filtered gas can pass from one opening side to the other opening side.
框體之形狀,只要是可收置過濾器濾材F1之形狀,並無特別限制,可舉例如,直方體狀和圓形狀等。又,框體之材質並無特別限制,可使用鋁製者。 The shape of the casing is not particularly limited as long as it can accommodate the shape of the filter medium F1, and examples thereof include a rectangular parallelepiped shape and a circular shape. Further, the material of the frame is not particularly limited, and aluminum may be used.
過濾器濾材F1和框體之間充填有填縫劑。該填縫劑可使用例如,雙液型環氧樹脂填縫劑(具體而言,為將 公司(Henkel AG & Co.KGaA)所製造之MACROPLAST 8104MC-18和,MACROPLAST UK5400以3:1之比例混合而成者)。 A sealant is filled between the filter medium F1 and the frame. The caulking agent can use, for example, a two-liquid epoxy resin caulk (specifically, The company (Henkel AG & Co. KGaA) manufactured by MACROPLAST 8104MC-18 and MACROPLAST UK5400 in a ratio of 3:1).
此種過濾器單元適合作為無塵室等的HEPA(High Efficiency Particulate Air)過濾器,以及ULPA(Ultra Low Penetration Air)過濾器使用。 Such a filter unit is suitable for use as a HEPA (High Efficiency Particulate Air) filter such as a clean room or a ULPA (Ultra Low Penetration Air) filter.
如上述所構成的過濾器單元是使過濾器濾材F1之長度L1方向相對於被過濾氣體的流通方向配置成相交叉(具體而言,概呈垂直相交)。亦即,過濾器單元是配置成使被過濾氣體從過濾器濾材F1之高度L2方向接觸過濾器濾材F1。藉此,使從框體其中一方的開口部流入過濾器單元內部之被過濾氣體在內部空間通過過濾器濾材F1以從框體另一方的開口部排出。 The filter unit configured as described above is such that the length L1 direction of the filter medium F1 is arranged to intersect with each other in the flow direction of the filtered gas (specifically, substantially perpendicularly intersects). That is, the filter unit is disposed such that the filtered gas contacts the filter medium F1 from the height L2 of the filter medium F1. Thereby, the filtered gas that has flowed into the inside of the filter unit from one of the openings of the casing is discharged through the filter medium F1 in the internal space from the other opening of the casing.
如以上所述,透過本發明之過濾器濾材的製造裝置,可在平板部彼此之間隔變寬時,防止相鄰平板部之間發生放電,並可抑制因為此種放電在濾材胚料形成貫通孔而導致過濾器濾材之集塵效率下降。 As described above, according to the apparatus for manufacturing a filter medium of the present invention, when the interval between the flat plate portions is widened, the discharge between the adjacent flat plate portions can be prevented, and the formation of the filter material in the filter material can be suppressed. The pores cause a decrease in the dust collecting efficiency of the filter medium.
即,製造裝置1,藉由設置除電裝置6,可以在打褶展開部7使平板部F1b彼此之間隔變寬時,防止相鄰平板 部F1b之間發生放電。具體而言,在打褶壓縮部5之濾材胚料A搬送方向下游側的端部處,濾材胚料A中形成皺褶狀之區域(以下,亦記載為皺褶狀區域),會變成使平板部F1b彼此之間隔相接近之狀態。也就是說,在打褶壓縮部5之濾材胚料A搬送方向下游側的端部處,濾材胚料A之皺褶狀區域變成帶電狀態,故藉由在此端部從除電裝置6對濾材胚料A放出離子,可透過濾材胚料A與離子之接觸而使濾材胚料A被消除靜電。藉此,就算在打褶展開部7使平板部F1b彼此之間隔變寬時,仍然可以防止相鄰平板部F1b之間發生放電。 That is, in the manufacturing apparatus 1, by providing the static eliminating device 6, it is possible to prevent the adjacent flat plates when the pleating development portion 7 widens the interval between the flat plate portions F1b. A discharge occurs between the portions F1b. Specifically, in the end portion on the downstream side in the conveyance direction of the filter material blank A in the pleating and compressing portion 5, a region in which the crepe-like region (hereinafter also referred to as a crease-like region) is formed in the filter material blank A becomes The state in which the flat plate portions F1b are spaced apart from each other. In other words, at the end portion on the downstream side in the conveying direction of the filter material blank A of the pleating and compressing portion 5, the crease-like region of the filter material blank A becomes a charged state, so that the filter medium is removed from the static eliminating device 6 at this end portion. The billet A emits ions, which can pass through the contact between the filter material billet A and the ions, so that the filter material billet A is eliminated from static electricity. Thereby, even when the pleating development portion 7 widens the interval between the flat plate portions F1b, it is possible to prevent the discharge from occurring between the adjacent flat plate portions F1b.
又,由於濾材胚料A之皺褶狀區域是以受到挾持部5a包夾之狀態搬送,同時以受加壓部5b加壓之狀態搬送,會因為與挾持部5a以及加壓部5b的滑動接觸而容易帶電。然而,由於會在加壓部5b之濾材胚料A搬送方向下游側之端部從除電裝置6對濾材胚料A放出離子,故可在進入打褶展開部7前(亦即,相鄰平板部間F1b不發生放電之狀態下)使濾材胚料A消除靜電。藉此,就算在打褶展開部7使平板部F1b彼此之間隔變寬時,仍然可以防止相鄰平板部F1b之間發生放電。 In addition, the wrinkled region of the filter material blank A is conveyed in a state of being sandwiched by the holding portion 5a, and is conveyed while being pressurized by the pressurizing portion 5b, and is slid with the grip portion 5a and the pressurizing portion 5b. It is easy to electrify when in contact. However, since ions are discharged from the static eliminating device 6 to the filter material blank A at the end portion on the downstream side in the conveying direction of the filter material blank A of the pressurizing portion 5b, it is possible to enter the pleating development portion 7 (i.e., adjacent flat plates). In the state where the inter-part F1b does not discharge, the filter material blank A is eliminated from static electricity. Thereby, even when the pleating development portion 7 widens the interval between the flat plate portions F1b, it is possible to prevent the discharge from occurring between the adjacent flat plate portions F1b.
此外,以從濾材胚料A其中一面側朝濾材胚料A之搬送方向上游側放出離子的方式構成除電裝置6,可使從除電裝置6放出的離子相對於濾材胚料A形成有效率的接觸。藉此,可以有效率地執行濾材胚料A之消除靜電,且在打褶展開部7使平板部F1b彼此之間隔變寬時,也可以更有 效地防止相鄰平板部F1b之間發生放電。 Further, the static eliminating device 6 is configured such that ions are discharged from one surface side of the filter material blank A toward the upstream side in the conveying direction of the filter material blank A, and the ions discharged from the static eliminating device 6 can be efficiently contacted with the filter material blank A. . Thereby, the static elimination of the filter material blank A can be performed efficiently, and when the pleating development portion 7 widens the interval between the flat plate portions F1b, it is possible to further Effectively preventing discharge from occurring between adjacent flat plate portions F1b.
再者,本發明之過濾器濾材之製造裝置不限於上述實施形態,並可在不脫離本發明主旨的範圍下作各種變更。又,亦可隨意地採用並組合上述複數個實施形態之構成和方法等(其中一個實施形態之構成和方法等也可以適用至其他實施形態之構成和方法等),此外,當然亦可隨意選擇下列各種變更例之構成和方法等,並在上述實施形態之構成和方法等中採用。 In addition, the apparatus for manufacturing the filter medium of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. Further, the configuration, method, and the like of the above-described plural embodiments may be used arbitrarily (the configuration and method of one embodiment may be applied to other configurations, methods, and the like), and of course, may be arbitrarily selected. The configurations, methods, and the like of the following various modifications are employed in the configurations, methods, and the like of the above embodiments.
例如,在上述實施形態中,雖使其中一面側熔合道部B和另一面側熔合道部B形成為端部彼此隔著濾材胚料A相重疊,但不應以此為限,也可以形成不使該等端部彼此重疊。 For example, in the above-described embodiment, one of the side fusion side portions B and the other surface side fusion side portion B are formed such that the end portions overlap each other with the filter material blank A therebetween, but it should not be limited thereto or may be formed. The ends are not allowed to overlap each other.
又,上述實施形態中,雖然使用由單一層多孔質層A1和一對基材層A2形成的濾材胚料A構成過濾器濾材F1,但不應以此為限,也可以使用例如,由單一層多孔質層A1和單一層基材層A2形成的濾材胚料。或者,也可以使用僅由多孔質層A1形成的濾材胚料,也可以使用使單一層基材層A2包夾多孔質層A1所形成的濾材胚料。 Further, in the above-described embodiment, the filter medium F1 composed of the single-layer porous layer A1 and the pair of base material layers A2 is used, but the filter medium F1 is not limited thereto, and for example, a single sheet may be used. A filter material blank formed by a layer of porous layer A1 and a single layer of substrate layer A2. Alternatively, a filter material blank formed only of the porous layer A1 may be used, or a filter material blank formed by sandwiching the porous layer A1 with the single-layer base material layer A2 may be used.
又,在上述實施形態中,打褶加工部2雖然是採用反復方式,但不應以此為限,也可以構成為可藉由將濾材胚料A搬送至外周配置有複數個刀板的一對輥筒之間以對濾材胚料A進行打褶加工(旋轉式)。 Further, in the above-described embodiment, the pleating portion 2 is a repetitive method, but it should not be limited thereto, and a configuration in which a plurality of knives are disposed on the outer circumference by transporting the filter blank A may be employed. The filter material blank A is pleated (rotary) between the rolls.
又,在上述實施形態中,雖然是使用形成長條狀的濾材胚料A,但不應以此為限,例如也可以使用以一個方 向為長邊而形成單片體狀之濾材胚料。 Further, in the above-described embodiment, the filter material blank A which is formed into a long strip shape is used, but it should not be limited thereto. For example, one side may be used. A monolithic filter material blank is formed for the long side.
又,為了在打褶加工部2上有效地使濾材胚料A被拉伸展開,宜將夾送輥設置成具有高低差。又,為了防止打褶加工後的濾材胚料A帶電,宜對進行打褶加工之環境作加濕處理,並讓構成製造裝置1之構件接地。並且,在製造裝置1之所有步驟中,宜使濾材胚料A之帶電量為0.3kV以下。 Further, in order to effectively stretch the filter material blank A on the pleated portion 2, it is preferable to set the pinch roller to have a height difference. Further, in order to prevent the filter material blank A after the pleating process from being charged, it is preferable to humidify the environment in which the pleating process is performed, and to ground the member constituting the manufacturing apparatus 1. Further, in all the steps of the manufacturing apparatus 1, it is preferable that the amount of charge of the filter material blank A is 0.3 kV or less.
又,黏著劑塗布部3是透過夾送輥將形成有熔合道部B之濾材胚料A搬送至濾材形成部4。因此,為了不使熔合道部B接觸夾送輥,宜透過設有溝槽的夾送輥將形成有熔合道部B之濾材胚料A搬送至濾材形成部4。 Moreover, the adhesive application portion 3 conveys the filter material blank A on which the fusion fused portion B is formed, to the filter medium forming portion 4 via the pinch roller. Therefore, in order to prevent the fusion path portion B from contacting the pinch roller, the filter material blank A on which the fusion path portion B is formed is preferably conveyed to the filter medium forming portion 4 through the pinch roller provided with the groove.
在濾材形成部4所形成的過濾器濾材F1,可透過輸送帶等的搬送機構搬送至濾材形成部4。此種搬送機構之搬送速度是設定成,比往濾材形成部4之濾材胚料A的搬送速度慢。再者,宜依據搬送機構之搬送速度和往濾材形成部4之搬送速度之比以及黏著劑之塗布量,決定彎曲濾材胚料A之間隔。 The filter medium F1 formed in the filter medium forming portion 4 can be transported to the filter medium forming portion 4 through a transport mechanism such as a conveyor belt. The conveyance speed of the conveyance mechanism is set to be slower than the conveyance speed of the filter material blank A to the filter medium forming portion 4. Further, it is preferable to determine the interval of the curved filter material blank A in accordance with the ratio of the conveying speed of the conveying mechanism and the conveying speed to the filter forming portion 4 and the amount of the adhesive applied.
以下,將就本發明之實施例作說明。又,本發明非受限於下述實施例者。 Hereinafter, embodiments of the invention will be described. Further, the present invention is not limited to the embodiments described below.

3.過濾器濾材之製作 3. Filter filter production
使用上述實施形態之製造裝置1,對濾材胚料A作打褶加工,同時在打褶壓縮部5進行對濾材胚料A之皺褶狀區域之特性賦予。具體而言,以特定的張力陸續傳送濾材胚料A,並以打褶加工速度為70PLT/min,高度L2為35mm的方式進行打褶加工。又,打褶壓縮部5中對濾材胚料A之加熱溫度是設定成80℃。又,除電裝置6是使用(KEYENCE)製造的SJ-HA。之後,在黏著劑塗布部3對濾材 胚料A塗布黏著劑,並在濾材形成部4形成過濾器濾材F1。再者,於打褶展開部7測定濾材胚料A之皺褶狀區域的帶電量。測定結果,如下述表1所示。 According to the manufacturing apparatus 1 of the above-described embodiment, the filter material blank A is pleated, and the characteristics of the crease-like region of the filter material blank A are imparted to the pleated compression portion 5. Specifically, the filter material blank A was successively conveyed at a specific tension, and pleating was performed so that the pleating speed was 70 PLT/min and the height L2 was 35 mm. Further, the heating temperature of the filter material blank A in the pleated compression portion 5 was set to 80 °C. Moreover, the static elimination device 6 is used SJ-HA manufactured by (KEYENCE). Thereafter, an adhesive is applied to the filter material blank A in the adhesive application portion 3, and a filter medium F1 is formed in the filter medium forming portion 4. Further, the charge amount of the wrinkle region of the filter material blank A is measured in the pleating development portion 7. The measurement results are shown in Table 1 below.
4.評估 4. Evaluation
將以實施例1~6之製造裝置1所製得的各過濾器濾材F1拉伸展開成打褶加工前之狀態而形成片狀者作為試驗樣品。 Each of the filter media F1 obtained in the production apparatus 1 of each of Examples 1 to 6 was stretched and developed into a state before the pleating process to form a sheet shape as a test sample.
並且,依據EN1822-3(2009)所規定的方法,針對各試驗樣品進行捕集效率之測定。具體而言,是將試驗樣品設置在圓環狀之支架(有效面積:100cm2)上,進行捕集效率之測定。測定條件為,使含有聚α-烯烴(poly-alpha-olefin,簡稱為PAO)之粒子(粒徑:0.1μm以上0.2μm以下,個數:108個/L以上)的被過濾氣體(穿透流速:5.3cm/sec)通過試驗樣品,以微粒子計(Particle-Counter)測定通過試驗樣品之PAO粒子的濃度。並且,透過以下之式(1)算出捕集效率。各實施例之試驗過濾器之捕集效率,如下述表1所示。 Further, the measurement efficiency of each test sample was measured in accordance with the method specified in EN1822-3 (2009). Specifically, the test sample is disposed in the annular holder (effective area: 100cm 2), the collection efficiency was measured. The measurement conditions are such that the particles containing the poly-α-olefin (PAO) particles (particle diameter: 0.1 μm or more and 0.2 μm or less, number: 10 8 /L or more) are filtered. Permeation flow rate: 5.3 cm/sec) The concentration of PAO particles passing through the test sample was measured by a particle-counter by a test sample. Then, the collection efficiency is calculated by the following formula (1). The collection efficiency of the test filters of the respective examples is shown in Table 1 below.
捕集效率(%)={1-(通過試驗過濾器之粒子濃度/被過濾氣體之粒子濃度)}×100………(1) Collection efficiency (%) = {1 - (particle concentration through the test filter / particle concentration of the filtered gas)} × 100... (1)
<比較例> <Comparative example>
以和實施例相同之方法,製作多孔質片體以及濾材胚料A。並且,除了製作過濾器濾材時不使用除電裝置6以外,以和實施例相同的方法製作試驗過濾器,並使用該試驗過濾器計測通過之粒子,以進行捕集效率之計算。各測定位置之捕集效率,如下述表1所示。 A porous sheet and a filter material blank A were produced in the same manner as in the examples. Further, a test filter was produced in the same manner as in the example except that the static filter device 6 was not used in the production of the filter medium, and the passed particles were measured using the test filter to calculate the collection efficiency. The collection efficiency at each measurement position is shown in Table 1 below.
<總結> <summary>
參見表1,可看出實施例這組之捕集效率具較高的數值。這是因為,在實施例中,藉由使用除電裝置6,可在打褶壓縮部5之下流側端部,對濾材胚料A之皺褶狀區域放出離子。因此,於平板部F1b彼此之間隔變寬前(亦即,皺褶狀區域被搬送至打褶展開部7之前),可使濾材胚料A消除靜電。並發現可藉此在平板部F1b彼此之間隔變寬時(亦即,皺褶狀區域被搬送至打褶展開部7之時),防止相鄰平板部F1b彼此之間發生放電。 Referring to Table 1, it can be seen that the capture efficiency of the set of examples has a higher value. This is because, in the embodiment, by using the static eliminating device 6, the flow side end portion can be discharged under the pleated compression portion 5, and ions are released to the creased region of the filter material blank A. Therefore, before the interval between the flat plate portions F1b is widened (that is, before the pleated region is conveyed to the pleating development portion 7), the filter material blank A can be eliminated from static electricity. It has been found that when the interval between the flat plate portions F1b is widened (that is, when the pleated region is conveyed to the pleating development portion 7), discharge between the adjacent flat plate portions F1b is prevented.
從而,發現可藉由在打褶壓縮部之下游側端部設置對濾材胚料之皺褶狀區域放出離子之除電裝置,抑制因放電於濾材胚料形成貫通孔而使過濾器濾材的捕集效率下降。 Therefore, it has been found that by providing a static eliminating device for discharging ions to the wrinkle-like region of the filter material billet at the downstream end portion of the pleated compressing portion, it is possible to suppress the trapping of the filter medium by the formation of the through-hole by the discharge of the filter material. The efficiency is declining.
