Description

運送帶製造裝置 Conveyor manufacturing equipment

本發明係關於用以製造電子零件收納用運送帶之運送帶製造裝置。 The present invention relates to a conveyor belt manufacturing apparatus for manufacturing a conveyor belt for storing electronic parts.

一般而言，作為收納電子零件(特別是晶片電阻、晶片LED、晶片電容器等非常小的晶片零件)等之包裝體，可使用以頂端覆蓋膠帶(以下，亦僅稱「覆蓋膠帶」。)封閉電子零件收納用運送帶(以下，亦僅稱「運送帶」。)而構成之包裝體。 Generally speaking, as a packaging body for storing electronic parts (especially very small chip parts such as chip resistors, chip LEDs, chip capacitors, etc.), a top cover tape (hereinafter, also simply referred to as "cover tape") can be used for sealing. A packaging body constituted by a conveyor belt (hereinafter, also simply referred to as a "conveyor belt") for storing electronic parts.

作為運送帶，可使用於帶狀薄片的一部分，藉由沖壓加工形成穿通孔後在薄片下表面貼附底帶，形成凹形零件收納部(袋部)之沖壓運送帶(參照例如專利文獻1)、於帶狀薄片的一部分，藉由壓縮加工形成袋部之衝壓運送帶(參照例如專利文獻2)、於帶狀薄片的一部分，藉由成形加工(加壓成形、真空滾筒成形、衝壓成形等)形成袋部之壓紋運送帶(參照例如專利文獻3)等。 As the conveyer belt, a part of the belt-shaped sheet can be punched by forming a through hole by punching, and a bottom belt is attached to the lower surface of the sheet to form a concave part storage part (bag portion). ). A part of the belt-shaped sheet is formed by a compression conveying belt (refer to, for example, Patent Document 2), and a part of the belt-shaped sheet is subjected to forming processing (pressure forming, vacuum roll forming, press forming). Etc.) forming an embossed conveyor belt for a bag portion (see, for example, Patent Document 3) and the like.

如圖9、圖10、圖11所示之沖壓運送帶及衝壓運送帶可作為薄片基材使用，紙製者為主流。此等紙製運送帶在將電子零件對表面安裝機喂料之際，會自薄片本身產生紙粉。因此紙粉，有會發生電子零件焊接不良或電子零件吸附噴嘴被阻塞之問題。且有袋部內起毛、吸濕導致袋部尺寸變化、由於因安裝時剝離覆蓋膠帶之際產生之靜電而帶電等，電子零件吸附噴嘴易於發生誤拾之問題。 As shown in FIGS. 9, 10 and 11, the punching conveyor belt and the punching conveyor belt can be used as a sheet substrate, and papermakers are the mainstream. These paper conveyor belts generate paper dust from the sheet itself when feeding electronic parts to a surface mount machine. Therefore, paper powder may cause problems such as poor welding of electronic parts or blocking of the suction nozzles of electronic parts. In addition, there are problems such as fluffing and moisture absorption in the bag portion, change in the size of the bag portion, and charging due to static electricity generated when the cover tape is peeled off during installation, and the electronic component suction nozzle is prone to mistaken pickup.

且一般於上述沖壓運送帶，會對應收納之電子零件之高度，設定薄片厚度(與袋部深度相同)。因此，於用來收納高度低的電子零件之沖壓運送帶，需減少薄片厚度。此時，因薄片強度不足，於收納電子零件，封閉覆蓋膠帶之黏貼程序(以下亦僅稱「黏貼」。)或電子零件安裝程序中，以鏈輪輸送沖壓運送帶之際，沖壓運送帶之進給孔會變形。因如此之變形，發生進給不良，而有黏貼時收納穩定性降低或安裝時發生誤拾之問題。且於薄片下表面需貼附底帶，故資材購入費或加工費等增加，而有導致運送帶成本增加之問題。 And generally, the thickness of the sheet (same as the depth of the bag portion) is set on the stamped conveyor belt according to the height of the stored electronic parts. Therefore, it is necessary to reduce the sheet thickness in a punching and conveying belt for storing electronic components having a low height. At this time, due to the insufficient strength of the sheet, in the process of adhering electronic parts and sealing the adhesive tape (hereinafter also referred to as "adhesive") or in the process of installing electronic parts by sprocket conveyors, press the conveyor belt. The feed holes are deformed. Due to such deformation, poor feeding occurs, and storage stability is reduced during sticking, or misplacement occurs during installation. In addition, a bottom tape needs to be attached to the lower surface of the sheet, so the purchase cost of materials or processing costs increase, and there is a problem that the cost of the conveyor belt increases.

另一方面，如圖12、圖13、圖14所示之壓紋運送帶中，薄片袋部之內側呈突起狀。因此，與前述沖壓運送帶或前述衝壓運送帶併用時，需對黏貼機及表面安裝機進行裝置改造或零件交換，需莫大的成本。且將壓紋運送帶捲繞於捲筒而輸送之際，於薄片內側之突起會造成負載。因此，有零件收納部變形或捲繞崩塌、捲繞鬆弛發生之問題。且於黏貼後將壓紋運送帶捲繞於捲筒時，於外側層捲繞之薄片內側突起會對於內側層捲繞之袋部部分之覆蓋膠帶加壓。其結果，有覆蓋膠帶損傷或電子零件破損之問題。 On the other hand, in the embossed conveyor belt shown in FIGS. 12, 13, and 14, the inside of the sheet bag portion is projected. Therefore, when it is used in combination with the aforementioned punching conveyor belt or the aforementioned punching conveyor belt, it is necessary to perform device modification or parts exchange on the bonding machine and the surface mounting machine, which requires a great cost. In addition, when the embossed conveyor belt is wound around a roll and conveyed, a protrusion on the inside of the sheet causes a load. Therefore, there is a problem in that the component housing portion is deformed, the coil is collapsed, and the coil is loosened. And when the embossed conveyor belt is wound on the roll after the sticking, the inner protrusion of the sheet wound on the outer layer will press the covering tape of the bag portion wound on the inner layer. As a result, there is a problem that the cover tape is damaged or electronic parts are damaged.

本發明可解決習知技術如此之問題點。本發明之目的在於提供一種運送帶製造裝置，可製造黏貼及表面安裝穩定性提升，經無塵化對應之電子零件收納用運送帶。 The invention can solve such a problem of the conventional technology.

首先，在說明本發明之運送帶製造裝置及運送帶製作用薄片製造裝置前，先說明關於包含使用本發明之運送帶製造裝置製造之電子零件收納用運送帶之包裝體。 First, before describing the conveyor belt manufacturing apparatus and the sheet manufacturing apparatus for manufacturing a conveyor belt of the present invention, a package including a conveyor belt for storing electronic parts manufactured using the conveyor belt manufacturing apparatus of the present invention will be described.

<包裝體> <Package body>

<<第1構成例>> << First configuration example >>

圖1係顯示包含由本發明之運送帶製造裝置製造之運送帶之包裝體之第1構成例之部分立體圖。圖2係沿圖1之線A-A之剖面圖。圖3係沿圖1之線B-B之剖面圖。圖4係顯示圖1包裝體具有之電子零件收納用運送帶之俯視圖。又，以下說明中，稱圖1~3中之上側為「上」，下側為「下」。且圖1中，為顯示由包裝體具有之運送帶之第1凹部內收納之電子零件，將包裝體具有之任意覆蓋膠帶部分卸除。且為更清楚地顯示第1凹部內部，將電子零件自前頭袋部內省略。 FIG. 1 is a partial perspective view showing a first configuration example of a packaging body including a conveyor belt manufactured by the conveyor belt manufacturing apparatus of the present invention. Fig. 2 is a sectional view taken along line A-A of Fig. 1. Fig. 3 is a sectional view taken along line B-B of Fig. 1. FIG. 4 is a plan view showing a conveyor belt for storing electronic parts included in the package of FIG. 1. FIG. In the following description, the upper side is referred to as "upper" and the lower side is referred to as "lower" in Figs. In addition, in FIG. 1, in order to show the electronic parts stored in the first recess of the conveyor belt included in the packaging body, any covering tape portion included in the packaging body is removed. In order to display the inside of the first recess more clearly, the electronic components are omitted from the front pocket portion.

包裝體100包含具有收納電子零件40之第1凹部(電子零件收納用凹部；袋部)12之電子零件收納用運送帶(以下亦僅稱「運送帶」。)1，與封閉運送帶1第1凹部12之開口之頂端覆蓋膠帶(以下亦僅稱「覆蓋膠帶」。)20。 The package 100 includes an electronic parts storage conveyor belt (hereinafter also simply referred to as a "conveyor belt") 1 having a first recessed portion (recessed portion for storing electronic components; a bag portion) 12 that stores the electronic components 40, and a closed conveyance belt. 1 The top end of the opening of the recessed portion 12 is covered with a tape (hereinafter also referred to simply as "covering tape") 20.

圖1~3所示之運送帶1由帶狀薄片10構成，為樹脂製。此運送帶1上側第1面15包含沿其長邊方向呈1列配置之複數第1凹部12，與和複數第1凹部12平行而呈1列配置之複數進給孔11。 The conveying belt 1 shown in FIGS. 1 to 3 is composed of a belt-like sheet 10 and is made of resin. The first surface 15 on the upper side of this conveyor belt 1 includes a plurality of first recessed portions 12 arranged in a row along the longitudinal direction thereof, and a plurality of feed holes 11 arranged in a row in parallel with the plurality of first recessed portions 12.

且本實施形態中，運送帶1中第1面15之相反側(下側)第2面13大致平坦。 Further, in the present embodiment, the second surface 13 on the opposite side (lower side) of the first surface 15 in the conveyor belt 1 is substantially flat.

換言之，本實施形態中，運送帶1包含朝第1面15側開放之有底第1凹部12，與穿通第1面15及第2面13之進給孔11。第2面13相對於第1凹部12底部及其外周部附近，以實質上無段差之面構成。 In other words, in the present embodiment, the conveying belt 1 includes a bottomed first recessed portion 12 opened toward the first surface 15 side, and a feed hole 11 passing through the first surface 15 and the second surface 13. The second surface 13 is formed with a substantially non-stepped surface with respect to the bottom of the first recessed portion 12 and the vicinity of the outer peripheral portion.

如圖1所示，複數第1凹部12以等間隔方式設置，俾沿帶狀薄片10之長邊方向，於第1面15排成1列。於此等第1凹部12，可分別收納電子零件40。 As shown in FIG. 1, the plurality of first recessed portions 12 are arranged at equal intervals, and are arranged in a row on the first surface 15 along the long side direction of the band-shaped sheet 10. The first recessed portions 12 can accommodate the electronic components 40 respectively.

且如圖1所示，複數進給孔11以等間隔方式設置，俾沿薄片10之長邊方向穿通第1面15及第2面13，排成1列。惟不使用進給孔而實施將電子零件對表面安裝機喂料時，亦可省略此進給孔11之形成。 Also, as shown in FIG. 1, the plurality of feed holes 11 are arranged at equal intervals, and the cymbals pass through the first surface 15 and the second surface 13 along the long side direction of the sheet 10 and are arranged in a row. However, when feeding electronic components to a surface mounter without using a feed hole, the formation of the feed hole 11 may be omitted.

又，本實施形態中，如圖1、2所示，電子零件40其整體形狀呈立方體狀。收納電子零件40之第1凹部12之形狀亦對應電子零件40之整體形狀而呈立方體狀。因此，第1凹部12之俯視形狀雖呈長方形狀，但亦可對應應收納之電子零件40之形狀，呈如三角形、五角形、六角形之多角形狀或圓形狀等。 In this embodiment, as shown in FIGS. 1 and 2, the overall shape of the electronic component 40 is a cube. The shape of the first recessed portion 12 accommodating the electronic component 40 also has a cube shape corresponding to the overall shape of the electronic component 40. Therefore, although the planar shape of the first recessed portion 12 is rectangular, it can also correspond to the shape of the electronic component 40 to be stored, such as a triangular, pentagonal, or hexagonal polygonal shape or a circular shape.

且於第1凹部12內周面，為提升電子零件吸附噴嘴之拾取性等，亦可沿運送帶1之厚度方向，形成凸條或凹條。 In addition, on the inner peripheral surface of the first recessed portion 12, in order to improve the pickup performance of the suction nozzle of the electronic component, etc., a convex strip or a concave strip may be formed along the thickness direction of the conveying belt 1.

且於第1凹部12之底面，亦可設置段差。藉此，例如於電子零件40之底面形成端子等時，可防止此端子接觸第1凹部12之底面。因此，可確實防止於運送帶1輸送時等，端子等破損。 In addition, a step may be provided on the bottom surface of the first concave portion 12. Thus, for example, when a terminal is formed on the bottom surface of the electronic component 40, the terminal can be prevented from contacting the bottom surface of the first recessed portion 12. Therefore, it is possible to reliably prevent damage to the terminals and the like during the conveyance of the conveyor belt 1 and the like.

如圖1、2所示，複數進給孔11排成1列以等間隔方式設置，俾形成與複數第1凹部12平行之列。此等進給孔11用於將由第1凹部12收納之電子零件40對表面安裝機喂料之際。 As shown in FIGS. 1 and 2, the plurality of feed holes 11 are arranged in a row at equal intervals, and the rows are formed in a row parallel to the plurality of first concave portions 12. These feeding holes 11 are used when feeding the electronic component 40 accommodated in the first recessed portion 12 to the surface mounter.

且進給孔11之尺寸在運送帶1之短邊方向寬為8mm時，其平均內徑宜設定為約Φ1.5~1.6mm，更宜設定為約Φ1.5~1.55mm。運送帶1之短邊方向寬為4mm時，進給孔11之尺寸其平均內徑宜設定為約Φ0.76~0.84mm，更宜設定為約Φ0.78~0.82mm。藉此，可確實實施以表面安裝機使用進給孔11包裝體100之喂料。 And when the size of the feed hole 11 is 8mm in the short side direction of the conveyor belt 1, its average inner diameter should be set to about Φ1.5 ~ 1.6mm, more preferably about Φ1.5 ~ 1.55mm. When the width of the short side of the conveyor belt 1 is 4mm, the average inner diameter of the size of the feed hole 11 should be set to about Φ0.76 ~ 0.84mm, and more preferably set to about Φ0.78 ~ 0.82mm. Thereby, the feeding of the package 100 using the feed hole 11 by the surface mounting machine can be performed reliably.

又，複數第1凹部12與複數進給孔11雖皆沿薄片10之長邊方向排成1列設置，但第1凹部12及進給孔11之配置間隔未特別限定。例如圖4(a)、(b)所示，可沿該長邊方向，於2個進給孔11之間配置2個以上第1凹部12，亦可如圖4(c)所示，於2個進給孔11之間配置1個第1凹部12。 In addition, although the plurality of first recessed portions 12 and the plurality of feed holes 11 are arranged in a row along the longitudinal direction of the sheet 10, the arrangement interval of the first recessed portions 12 and the feed holes 11 is not particularly limited. For example, as shown in Figs. 4 (a) and (b), two or more first recesses 12 may be arranged between the two feed holes 11 along the longitudinal direction, or as shown in Fig. 4 (c), A first recessed portion 12 is arranged between the two feed holes 11.

又，為圖4(a)之構成時，可使用運送帶1之短邊方向寬為8mm，各進給孔11之長邊方向之間隔為4mm，第1凹部12之間隔為2mm之構成(a1)、運送帶1之短邊方向寬為8mm，各進給孔11之長邊方向之間隔為2mm，第1凹部12之間隔為1mm之構成(a2)與運送帶1之短邊方向寬為4mm，各進給孔11之長邊方向之間隔為2mm，第1凹部12之間隔為1mm之構成(a3)。各構成(a1)、(a2)及(a3)中F1宜設定為0±0.05mm，更宜設定為0±0.03mm。各構成(a1)、(a2)及(a3)中F2宜分別設定為 2±0.05mm、1±0.05mm及1±0.05mm，更宜分別設定為2±0.03mm、1±0.03mm及1±0.03mm。各構成(a1)、(a2)及(a3)中G宜分別設定為3.5±0.05mm、3.5±0.05mm及1.8±0.05mm，更宜分別設定為3.5±0.03mm、3.5±0.03mm及1.8±0.03mm。 In the configuration shown in FIG. 4 (a), the width of the short-side direction of the conveyor belt 1 is 8 mm, the interval between the long-side directions of the feed holes 11 is 4 mm, and the interval between the first recesses 12 is 2 mm ( a1) The width of the short side of the conveyor belt 1 is 8mm, the interval between the long sides of each feed hole 11 is 2mm, and the interval between the first recesses 12 is 1mm (a2) and the width of the short side of the conveyor 1 It is 4 mm, the space | interval of the longitudinal direction of each feed hole 11 is 2 mm, and the space | interval of the 1st recessed part 12 is 1 mm (a3). In each of the configurations (a1), (a2), and (a3), F1 should be set to 0 ± 0.05mm, and more preferably 0 ± 0.03mm. In each configuration (a1), (a2), and (a3), F2 should be set as 2 ± 0.05mm, 1 ± 0.05mm and 1 ± 0.05mm, more preferably set to 2 ± 0.03mm, 1 ± 0.03mm and 1 ± 0.03mm respectively. In each of the components (a1), (a2), and (a3), G should be set to 3.5 ± 0.05mm, 3.5 ± 0.05mm, and 1.8 ± 0.05mm, and more preferably 3.5 ± 0.03mm, 3.5 ± 0.03mm, and 1.8, respectively. ± 0.03mm.

且為圖4(b)之構成時，可使用運送帶1之短邊方向寬為8mm，各進給孔11之長邊方向之間隔為4mm，第1凹部12之間隔為1mm之構成(b)。該構成(b)中F1宜設定為0±0.05mm，更宜設定為0±0.03mm。構成(b)中F2宜設定為1±0.05mm，更宜設定為1±0.03mm。構成(b)中F3宜設定為2±0.05mm，更宜設定為2±0.03mm。構成(b)中F4宜設定為3±0.05mm，更宜設定為3±0.03mm。構成(b)中G宜設定為3.5±0.05mm，更宜設定為3.5±0.03mm。 In the configuration of FIG. 4 (b), the width of the short side of the conveyor belt 1 is 8 mm, the interval between the long sides of each feed hole 11 is 4 mm, and the interval between the first recesses 12 is 1 mm (b ). In this configuration (b), F1 should be set to 0 ± 0.05mm, and more preferably set to 0 ± 0.03mm. In the configuration (b), F2 should be set to 1 ± 0.05mm, and more preferably 1 ± 0.03mm.

In configuration (b), G should be set to 3.5 ± 0.05mm, and more preferably set to 3.5 ± 0.03mm.

且為圖4(c)之構成時，可使用運送帶1之短邊方向寬為8mm，各進給孔11之長邊方向之間隔為4mm，第1凹部12之間隔為4mm之構成(c)。該構成(c)中，F2宜設定為2±0.05mm，更宜設定為2±0.03mm。構成(c)中G宜設定為3.5±0.05mm，更宜設定為3.5±0.03mm。 In the configuration of FIG. 4 (c), the width of the short side of the conveyor belt 1 is 8 mm, the interval between the long sides of each feed hole 11 is 4 mm, and the interval between the first recesses 12 is 4 mm (c ). In this configuration (c), F2 is preferably set to 2 ± 0.05mm, and more preferably 2 ± 0.03mm. In configuration (c), G should be set to 3.5 ± 0.05mm, and more preferably set to 3.5 ± 0.03mm.

又，此等者中，構成(a1)或構成(a3)尤佳。藉此，可更確實實施以表面安裝機使用進給孔11包裝體100之喂料。 Among these, the constitution (a1) or the constitution (a3) is particularly preferable. Thereby, the feeding of the package 100 using the feed hole 11 by the surface mounting machine can be performed more reliably.

且由本發明之運送帶製造裝置製造之運送帶1係樹脂製。因運送帶1為樹脂製，將電子零件對表面安裝機喂料之際，如紙粉之微粉不自運送帶1本身產生。因此，可防止發生電子零件焊接不良或電子零件吸附噴嘴被阻塞。且可防止第1凹部12內起毛或吸濕造成第1凹部12尺寸變化。且更可防止安裝時剝離覆蓋膠帶20之際發生之靜電帶電，可提升電子零件吸附噴嘴之拾取性。藉此，充分對應無塵化，並可實現黏貼及表面安裝穩定性之提升、生產力之提升。 The conveyor belt 1 manufactured by the conveyor belt manufacturing apparatus of the present invention is made of resin. Because the conveyor belt 1 is made of resin, when electronic components are fed to the surface mounting machine, fine powder such as paper powder is not generated from the conveyor belt 1 itself. Therefore, it is possible to prevent the occurrence of poor soldering of the electronic parts or the blocking of the suction nozzles of the electronic parts. In addition, fluff or moisture absorption in the first recessed portion 12 can be prevented from causing a change in the size of the first recessed portion 12. Furthermore, it is possible to prevent static electricity from being generated when the cover tape 20 is peeled off during installation, and to improve the pickup performance of the suction nozzle of the electronic component. Thereby, it can fully respond to dust-free, and can improve the adhesion and surface mounting stability and productivity.

且因運送帶1為樹脂製，相較於紙製等時，薄片10之強度上昇。藉此， 即使在為收納高度低之電子零件40，減少薄片10之厚度時，亦可防止黏貼時或安裝時輸送運送帶1之際，運送帶1之進給孔11變形或運送帶1裂斷等。藉此，可充分抑制進給不良，提升黏貼時之收納穩定性或安裝時之拾取性。其結果，可實現黏貼及表面安裝穩定性之提升、生產力之提升。 In addition, since the conveying belt 1 is made of resin, the strength of the sheet 10 is increased compared to when it is made of paper or the like. With this, Even when the thickness of the sheet 10 is reduced for the storage of the electronic component 40 having a low height, it is possible to prevent the feeding hole 11 of the conveying belt 1 from being deformed or broken when the conveying belt 1 is conveyed during sticking or mounting. Thereby, it is possible to sufficiently suppress poor feeding, and improve the storage stability at the time of sticking or the pick-up property at the time of mounting. As a result, it is possible to improve adhesion and surface mounting stability, and productivity.

且作為構成運送帶1之樹脂，雖無特別限定，但可舉出例如聚苯乙烯、聚乙烯、聚丙烯、聚酯(聚對苯二甲酸乙二酯等)、聚碳酸酯、聚氯乙烯、聚醯胺、聚縮醛之各種樹脂(各種熱可塑性樹脂)，可組合此等者中1種或2種以上使用之。且可因應所需，於此等樹脂中混合碳黑、石墨、碳纖維等導電性填料。藉此，賦予運送帶1導電性，防止帶電，故可更防止靜電造成電子零件40被破壞。且亦可因應所需，添加發泡劑或滑劑等各種添加劑。且亦可於運送帶1表面，使矽氧系樹脂、氟系樹脂等所構成之剝離劑或具有導電性之被覆膜等成膜。且運送帶1之薄片10之層構成亦可為滿足此等要件之單層或是多層。 The resin constituting the conveyor belt 1 is not particularly limited, but examples thereof include polystyrene, polyethylene, polypropylene, polyester (such as polyethylene terephthalate), polycarbonate, and polyvinyl chloride. Various resins (poly thermoplastic resins) of polyamine, polyacetal, and various kinds of thermoplastic resins can be used in combination of one or more of them. According to requirements, conductive fillers such as carbon black, graphite, and carbon fiber can be mixed into these resins. Thereby, since electrical conductivity is provided to the conveyor belt 1 and electrification is prevented, the electronic component 40 can be more prevented from being damaged by static electricity. In addition, various additives such as a foaming agent and a lubricant can be added according to the needs. In addition, on the surface of the conveyor belt 1, a release agent composed of a silicone resin, a fluorine resin, or the like, or a conductive coating film can be formed. In addition, the layer structure of the sheet 10 of the conveyor belt 1 may be a single layer or multiple layers that satisfy these requirements.

且本實施形態中，第1凹部12形成於運送帶1之第1面15，運送帶1中第1面15之相反側之第2面13大致平坦。亦即，第2面13相對於第1凹部12之底部及其外周部附近，以實質上無段差之面構成。因此，即使在使用沖壓運送帶或衝壓運送帶用黏貼機及安裝機時，亦可與沖壓運送帶或衝壓運送帶相同地使用運送帶1。藉此，不需新的設備投資等，可提升價格競爭力。且將運送帶1捲繞於捲筒輸送之際，第2面13大致平坦，故可防止捲繞崩塌或捲繞鬆弛。藉此可防止第1凹部12變形或覆蓋膠帶20損傷。 Further, in the present embodiment, the first recessed portion 12 is formed on the first surface 15 of the conveyor belt 1, and the second surface 13 on the opposite side of the first surface 15 in the conveyor belt 1 is substantially flat. That is, the bottom surface of the second surface 13 with respect to the bottom portion of the first recessed portion 12 and the vicinity of the outer peripheral portion thereof is configured as a surface having substantially no step. Therefore, even when a punched conveyor belt or a sticking machine for a punched conveyor belt and a mounting machine are used, the conveyor belt 1 can be used in the same manner as a punched conveyor belt or a punched conveyor belt. In this way, no new equipment investment is required, which can enhance price competitiveness. In addition, when the conveying belt 1 is wound on a reel, the second surface 13 is substantially flat, so that it can prevent the winding from collapsing or being loosened. This prevents the first recessed portion 12 from being deformed or the cover tape 20 from being damaged.

且藉由如此之構造，可提供對應更薄型化之電子零件之運送帶。有時可對應包裝之電子零件40之大小適當設定第1凹部12之深度。亦即，將電子零件40收納在形成於運送帶1與覆蓋膠帶20之間之內部空間中，故為自保管時或輸送時之撞擊、污染等保護電子零件40，宜設計第1凹部12，俾相對於電子零件40之高度，設置些許間隙(例如0~0.3mm)。因此，伴隨著現今電子零件之薄型化，薄片本身亦需薄型化，故因此沖壓運送帶之強度不充分，有裂斷等之虞。另一方面，運送帶1中，即使配合包裝之電 子零件40減少第1凹部12之深度，亦不需使薄片10本身之厚度薄型化，故可具有充分之強度，直接對應經薄型化之電子零件。 With such a structure, it is possible to provide a conveyor belt corresponding to thinner electronic parts. The depth of the first recessed portion 12 may be appropriately set depending on the size of the electronic component 40 to be packaged. That is, the electronic component 40 is housed in the internal space formed between the conveyor belt 1 and the cover tape 20, so that the electronic component 40 is protected from impact, pollution, etc. during storage or transportation, and the first recess 12 should be designed.设置 A small gap (for example, 0 to 0.3 mm) is provided relative to the height of the electronic component 40. Therefore, with the current reduction in thickness of electronic parts, the sheet itself also needs to be reduced in thickness. Therefore, the strength of the punching conveyor belt is insufficient, and there is a risk of cracking and the like. On the other hand, in the conveyor belt 1, The sub-component 40 reduces the depth of the first recessed portion 12 and does not need to reduce the thickness of the sheet 10 itself. Therefore, it can have sufficient strength to directly correspond to the thinned electronic component.

且第1凹部12之深度為A(mm)，運送帶1中第1凹部12之底部之厚度為B(mm)，運送帶1中該凹部以外之部分之厚度為C(mm)時，宜形成第1凹部12及運送帶1，俾大致滿足A+B=C。所謂大致滿足A+B=C係例如滿足-0.1<C-(A+B)<0.1，滿足-0.05<C-(A+B)<0.05更佳。藉由滿足該式而形成第1凹部12及運送帶1，第2面13更平坦，可防止將運送帶1捲繞於捲筒而保管時或輸送之際捲繞崩塌或捲繞鬆弛。 When the depth of the first recessed portion 12 is A (mm), the thickness of the bottom of the first recessed portion 12 in the conveyor belt 1 is B (mm), and the thickness of the portion other than the recessed portion in the conveyor belt 1 is C (mm). The first recessed portion 12 and the conveyor belt 1 are formed, and 俾 substantially satisfies A + B = C. The so-called substantially satisfying A + B = C system satisfies, for example, -0.1 <C- (A + B) <0.1, and more preferably -0.05 <C- (A + B) <0.05. By satisfying this formula, the first recessed portion 12 and the conveying belt 1 are formed, and the second surface 13 is flatter, and it is possible to prevent the winding collapse or slack in the winding of the conveying belt 1 when it is wound around a roll and stored.

且對應包裝之電子零件40之高度設定第1凹部12之深度A。電子零件40之高度為Z(mm)時，第1凹部12之深度A宜滿足0≦A-Z≦0.3，滿足0.05≦A-Z≦0.15更佳。第1凹部12之深度A與電子零件40之高度Z之關係處於該較佳範圍內，故可提升黏貼時之收納穩定性或安裝時之拾取性，自運送帶1保管時或輸送時之撞擊、污染等防止電子零件40破損。且運送帶1中第1凹部12以外之部分之厚度C與運送帶1之薄片10之厚度大致相同。在此，C之厚度宜在0.1mm以上1.0mm以下，在0.2mm以上0.5mm以下更佳。厚度C處於該較佳範圍內，故運送帶1之生產力提升，且可防止運送帶1之進給孔11變形或運送帶1裂斷等。 And the depth A of the first recessed portion 12 is set corresponding to the height of the packaged electronic component 40. When the height of the electronic component 40 is Z (mm), the depth A of the first concave portion 12 should preferably satisfy 0 ≦ A-Z ≦ 0.3, and more preferably satisfy 0.05 ≦ A-Z ≦ 0.15. The relationship between the depth A of the first recessed portion 12 and the height Z of the electronic component 40 is within this preferred range, so it can improve the storage stability during the sticking or the pick-up performance during the installation, and the impact from the conveyor belt 1 during storage or transportation , Pollution, and the like to prevent damage to the electronic component 40. The thickness C of the portion other than the first recessed portion 12 in the conveying belt 1 is substantially the same as the thickness of the sheet 10 of the conveying belt 1. Here, the thickness of C is preferably 0.1 mm to 1.0 mm, and more preferably 0.2 mm to 0.5 mm. The thickness C is within the preferred range, so the productivity of the conveyor belt 1 is improved, and the feed holes 11 of the conveyor belt 1 can be prevented from deforming or the conveyor belt 1 from being broken.

且對應包裝之電子零件40之尺寸設定第1凹部12之尺寸。第1凹部12之尺寸為D(mm)×E(mm)，D≦E，電子零件40之尺寸為X(mm)×Y(mm)，X≦Y時，第1凹部12之尺寸及電子零件40之尺寸宜滿足0<D-X≦0.3，0<E-Y≦0.3，滿足0.05≦D-X≦0.15，0.05≦E-Y≦0.15更佳。第1凹部12之尺寸及電子零件40之尺寸處於該較佳範圍內，故可提升黏貼時之收納穩定性或安裝時之拾取性，自運送帶1保管時或輸送時之撞擊、污染等防止電子零件40破損。 The size of the first recessed portion 12 is set corresponding to the size of the packaged electronic component 40. When the size of the first recessed portion 12 is D (mm) × E (mm), D ≦ E, and when the size of the electronic component 40 is X (mm) × Y (mm), and X ≦ Y, the size of the first recessed portion 12 and electronics The size of the part 40 should satisfy 0 <DX ≦ 0.3, 0 <EY ≦ 0.3, more preferably 0.05 ≦ DX ≦ 0.15, and 0.05 ≦ EY ≦ 0.15. The size of the first recessed portion 12 and the size of the electronic component 40 are within the preferable range, so it can improve the storage stability during the sticking or the pick-up performance during the installation, and prevent the impact and pollution from the conveyor belt 1 during storage or transportation. The electronic component 40 is broken.

且運送帶1以第2面13為捲筒(芯材)側，在捲繞之狀態下被保管、輸送。用於此時之捲筒其直徑宜約5~300mm，約30~250mm則更佳。 In addition, the conveying belt 1 has the second surface 13 as the roll (core material) side, and is stored and conveyed in a wound state. The diameter of the roll used at this time should be about 5 ~ 300mm, more preferably about 30 ~ 250mm.

在此，由第1凹部12收納之電子零件40如圖2所示呈長方形狀時，若以前述Y(mm)×X(mm)記載電子零件40俯視時之尺寸，通常使用0.6mm×0.5mm、0.6mm×0.3mm、0.4mm×0.2mm之尺寸之電子零件40。且有人說將來會使用0.3mm×0.15mm、0.2mm×0.1mm之尺寸之電子零件40。因此，可將Y(mm)約0.2~0.6mm，X(mm)約0.1~0.5mm之尺寸之電子零件40收納於第1凹部12。 Here, when the electronic component 40 accommodated in the first recessed portion 12 is rectangular as shown in FIG. 2, if the dimensions of the electronic component 40 in plan view are described by the aforementioned Y (mm) × X (mm), usually 0.6mm × 0.5 Electronic components 40 with dimensions of mm, 0.6mm × 0.3mm, 0.4mm × 0.2mm. And some people say that in the future, electronic parts 40 with dimensions of 0.3mm × 0.15mm and 0.2mm × 0.1mm will be used. Therefore, the electronic component 40 having a size of about 0.2 mm to about 0.6 mm in Y (mm) and about 0.1 mm to about 0.5 mm in X (mm) can be stored in the first recessed portion 12.

且通常設定如此之電子零件40之高度Z(mm)約0.1~0.35mm。 And the height Z (mm) of such an electronic component 40 is usually set to about 0.1 to 0.35 mm.

假定捲繞運送帶1之捲筒之直徑φ為F(mm)，捲繞之際，第1凹部12之開口部側，亦即覆蓋膠帶20側平坦化時，第1凹部12之深度A之變化量G(mm)經本案發明人探討結果得知可以下述式(1)表示。此時，變化量G(mm)減小第1凹部12之深度A而作用，故第1凹部12之實質深度為A-G(mm)。 It is assumed that the diameter φ of the roll of the winding conveyor belt 1 is F (mm). At the time of winding, the opening side of the first recessed portion 12, that is, when the side of the cover tape 20 is flattened, The amount of change G (mm) was found from the results of the present inventors' investigation, and can be expressed by the following formula (1). At this time, the amount of change G (mm) acts by reducing the depth A of the first recessed portion 12, so the substantial depth of the first recessed portion 12 is A-G (mm).

且假定捲繞之際，第1凹部12之底部側平坦化時，可以下述式(2)表示第1凹部12之深度A之變化量H(mm)。此時，變化量H(mm)增大第1凹部12之深度A而作用，故第1凹部12之實質深度為A+H(mm)。 When the bottom side of the first recessed portion 12 is flattened at the time of winding, the change amount H (mm) of the depth A of the first recessed portion 12 can be expressed by the following formula (2). At this time, the amount of change H (mm) acts by increasing the depth A of the first recessed portion 12, so the substantial depth of the first recessed portion 12 is A + H (mm).

在此，使用上述式(1)及式(2)，求取將如上述之尺寸之電子零件40收納於第1凹部12內之狀態下，運送帶1捲繞於直徑5~300mm之捲筒之際之變化量G及變化量H，則變化量G及變化量H分別在2.0×10-5~ 1.33×10-2mm，及2.0×10-5~1.46×10-2mm之範圍內。 Here, using the above formulas (1) and (2), in a state in which the electronic components 40 having the dimensions described above are housed in the first recessed portion 12, the conveyor belt 1 is wound around a reel having a diameter of 5 to 300 mm. The amount of change G and the amount of change H at this time are respectively within the range of 2.0 × 10 -5 to 1.33 × 10 -2 mm and 2.0 × 10 -5 to 1.46 × 10 -2 mm .

又，以第1凹部12俯視時之大小較電子零件40俯視時之大小縱及橫皆大0.05mm，第1凹部12之底部之厚度為0.1mm，第1凹部12之深度與電子零件40之高度之差(A-Z)為0.15mm之情形為代表例，求取該變化量G及變化量H。 In addition, the size of the first recessed portion 12 in plan view is 0.05 mm larger than the size of the electronic component 40 in plan view. The thickness of the bottom of the first recessed portion 12 is 0.1 mm. The depth of the first recessed portion 12 and the size of the electronic component 40 are 0.05 mm. A case where the difference in height (AZ) is 0.15 mm is a representative example, and the change amount G and the change amount H are obtained.

因此，若將第1凹部12之深度與電子零件40之高度之差(A-Z)如上述，設定為作為更佳範圍之約0.05≦A-Z≦0.15，則變化量G及變化量H相較於(A-Z)皆小。藉此，即使將運送帶1捲繞於如上述之直徑之捲筒，亦可確實抑制或防止因電子零件40覆蓋膠帶20被撐破，或於覆蓋膠帶20發生捲皺。且可更強固地進行運送帶1相對於捲筒之捲繞，故可確實防止發生捲繞崩塌或捲繞鬆弛。 Therefore, if the difference (AZ) between the depth of the first concave portion 12 and the height of the electronic component 40 is set as described above as about 0.05 ≦ AZ ≦ 0.15 as a better range, the change amount G and the change amount H are compared to ( AZ) are small. Thereby, even if the conveying belt 1 is wound on a roll having the above-mentioned diameter, it is possible to reliably suppress or prevent the electronic component 40 from being broken by the cover tape 20 or the wrinkle from occurring on the cover tape 20. Furthermore, since the winding of the conveying belt 1 with respect to the roll can be performed more firmly, it is possible to reliably prevent the occurrence of winding collapse or winding slack.

且該第1凹部12之內側緣部14宜以曲率半徑在0.2mm以下之方式彎曲，在0.1mm以下更佳。藉由如此彎曲第1凹部12，即使在包裝薄型電子零件40時，亦可增大第1凹部12與底面正交之側壁面直線部。藉此，可防止凹部側壁面自底部橫跨緣部擴張，故可提升電子零件40之收納穩定性。 In addition, the inner edge portion 14 of the first recessed portion 12 is preferably curved so that the curvature radius is 0.2 mm or less, and more preferably 0.1 mm or less. By bending the first recessed portion 12 in this manner, even when the thin electronic component 40 is packaged, the side wall surface straight portion of the first recessed portion 12 orthogonal to the bottom surface can be increased. Thereby, the side wall surface of the recessed portion can be prevented from expanding from the bottom to the edge portion, so the storage stability of the electronic component 40 can be improved.

圖1、2所示之覆蓋膠帶20呈帶狀。覆蓋膠帶20貼合收納電子零件40於第1凹部12內之狀態之運送帶1之第1面15。 The covering tape 20 shown in Figs. 1 and 2 has a band shape. The cover tape 20 is adhered to the first surface 15 of the conveyor belt 1 in a state where the electronic component 40 is stored in the first recessed portion 12.

藉由該構成，第1凹部12之開口由覆蓋膠帶20封閉。其結果，可使用包含運送帶1與覆蓋膠帶20之包裝體100，於第1凹部12收納電子零件40。 With this configuration, the opening of the first recessed portion 12 is closed by the cover tape 20. As a result, the electronic component 40 can be stored in the first recessed portion 12 by using the package 100 including the transporting belt 1 and the cover tape 20.

此覆蓋膠帶20可與運送帶1相同地以樹脂構成。作為構成覆蓋膠帶20之樹脂，可使用與於運送帶1舉出者相同者。 This covering tape 20 can be made of resin similarly to the conveying belt 1. As the resin constituting the cover tape 20, the same ones as those listed for the conveyer belt 1 can be used.

此等運送帶1與覆蓋膠帶20可例如以熱封黏接。可使用密封機，沿覆 蓋膠帶20長邊各緣進行熱封。又，亦可不使用熱封，代之以黏接劑黏接運送帶1與覆蓋膠帶20。 These conveyor belts 1 and the cover tape 20 can be adhered, for example, by heat sealing. Can use sealing machine The lid tape 20 is heat-sealed at each of the long edges. In addition, instead of using heat sealing, the conveyance belt 1 and the cover tape 20 may be bonded with an adhesive.

如此之包裝體100藉由沿包裝體100之長邊方向拽拉覆蓋膠帶20，自運送帶1剝離覆蓋膠帶20，藉此，取出電子零件40。 In such a package 100, the cover tape 20 is pulled along the longitudinal direction of the package 100, and the cover tape 20 is peeled from the transporting belt 1, thereby taking out the electronic component 40.

且此包裝體100以第2面13為捲筒(芯材)側捲繞，保管並輸送。藉此，可實現包裝體100保管時及輸送時之省空間化。 The packaging body 100 is wound around the second surface 13 as a roll (core material) side, and is stored and transported. Thereby, space saving can be achieved during storage and transportation of the package 100.

<運送帶製作用薄片> <Sheets for Conveyor Production>

具有如以上構成之包裝體100如前述，藉由貼合運送帶1與覆蓋膠帶20製得。以既定寬使運送帶製作用薄片155開縫(切斷)，俾包含沿其長邊方向分別呈1列配置之複數第1凹部12與複數進給孔11，藉此製造包含構成此包裝體100之第1凹部12與進給孔11之運送帶1。 The packaging body 100 having the above-mentioned structure is manufactured by bonding the conveyer belt 1 and the cover tape 20 as described above. The sheet 155 for making a conveyor belt is slit (cut) with a predetermined width, and the package includes a plurality of first recesses 12 and a plurality of feed holes 11 arranged in a row in the longitudinal direction of the conveyor belt. The first concave portion 12 of 100 and the conveying belt 1 of the feed hole 11.

且沿該長邊方向排列之複數第1凹部12之列，與沿該長邊方向排列之複數進給孔11之列沿製作用薄片155之短邊方向，交互配置，俾分別相互平行。 The rows of the plurality of first recesses 12 arranged along the long side direction and the rows of the plurality of feed holes 11 arranged along the long side direction are arranged alternately along the short side direction of the sheet 155 for production, and 俾 are parallel to each other.

該構成之運送帶製作用薄片155包含1對複數第1凹部12的1個列與複數進給孔11的1個列，藉由沿製作用薄片155之長邊方向，以既定寬使運送帶製作用薄片155開縫，獲得2個運送帶1。亦即，藉由沿圖5中所示之想像線使運送帶製作用薄片155開縫(切斷)，可製造2個包含1對複數第1凹部12的1個列與複數進給孔11的1個列之運送帶1。 The sheet 155 for producing a conveyor belt of this configuration includes a pair of one row of the plurality of first recessed portions 12 and one row of the plurality of feed holes 11, and the conveyor belt is formed in a predetermined width along the longitudinal direction of the sheet 155 for production.

That is, by slitting (cutting) the conveyer belt making sheet 155 along the imaginary line shown in FIG. 5, two rows including a pair of plural first recesses 12 and plural feed holes 11 can be manufactured. 1 of the conveyor belt 1.

藉由將此運送帶製作用薄片155以第1面15或第2面13為捲筒(芯材)側而捲繞，保管並輸送，可實現製作用薄片155保管時及輸送時之省空間化。且此時使用之捲筒其直徑宜約5~300mm，約30~250mm更佳。藉此，可實現製作用薄片155保管時及輸送時之省空間化，並可確實抑制或防止因此捲繞，第1凹部12及進給孔11非本意之變形。 By winding, storing and conveying the sheet 155 for producing the conveyor belt with the first surface 15 or the second surface 13 as the roll (core material) side, it is possible to save space during storage and transportation of the sheet 155 for production Into. And the diameter of the roll used at this time should be about 5 ~ 300mm, more preferably about 30 ~ 250mm. Thereby, it is possible to save space during storage and transportation of the manufacturing sheet 155, and it is possible to reliably suppress or prevent unintended deformation of the first recessed portion 12 and the feed hole 11 due to the winding.

<<第1實施形態>> << First Embodiment >>

可藉由適用本發明之運送帶製作用薄片之製造方法製造如以上構成之運送帶製作用薄片155。於以下，首先，說明關於用於此運送帶製作用薄片155之製造方法之運送帶製作用薄片製造裝置。 The conveyer belt manufacturing sheet 155 configured as described above can be manufactured by the manufacturing method of the conveyer belt manufacturing sheet to which the present invention is applied. In the following, first, a sheet production apparatus for producing a conveyor belt used in the method for producing the sheet 155 for producing an conveyor belt will be described.

圖7係顯示本發明之運送帶製作用薄片製造裝置之第1實施形態之立體圖。圖8係圖7之C箭視圖。又，以下說明中，稱圖7中上側為「上」，下側為「下」。 Fig. 7 is a perspective view showing a first embodiment of a sheet manufacturing apparatus for producing a conveyor belt according to the present invention. FIG. 8 is an arrow C view of FIG. 7. In the following description, the upper side in FIG. 7 is referred to as "upper", and the lower side is referred to as "downward".

圖7、8所示之運送帶製作用薄片製造裝置500包含薄片供給部700與成形部800。 The sheet manufacturing apparatus 500 for producing a conveyor belt shown in FIGS. 7 and 8 includes a sheet supply section 700 and a forming section 800.

薄片供給部700由本實施形態中，不圖示之擠製機與連接擠製機熔融樹脂噴吐部之T字模600構成。藉由此T字模600，對成形部800供給熔融狀態或軟化狀態之帶狀熔融薄片(sheet)。 The sheet supply unit 700 is composed of an extruder (not shown) and a T-shaped die 600 connected to the extruder molten resin ejection unit in this embodiment. By this T-shaped die 600, a molten sheet or a softened sheet-shaped molten sheet is supplied to the forming section 800.

T字模600係以擠製成形法將熔融狀態或軟化狀態之熔融薄片150在呈帶狀薄片之狀態下擠出之擠製成形部(送出成形部)。T字模600中，裝填有構成前述運送帶1(運送帶製作用薄片155)之樹脂呈熔融狀態之熔融樹脂。藉由將此熔融樹脂自T字模600具有之開口部601擠出，將作為呈帶狀之薄片之熔融狀態或軟化狀態之熔融薄片150連續送出。藉由以如此擠製成形法獲得熔融薄片150之構成，可使經形成之運送帶1(製作用薄片155)之薄片厚度穩定化。 The T-shaped die 600 is an extrusion-molded portion (feed-out portion) that is extruded in a molten state or a softened state from the molten sheet 150 in a state of a band-shaped sheet by an extrusion method. The T-shaped mold 600 is filled with a molten resin in which the resin constituting the aforementioned conveyor belt 1 (the conveyor belt production sheet 155) is in a molten state. By extruding the molten resin from the opening portion 601 provided in the T-shaped die 600, the molten sheet 150 in a molten state or a softened state as a sheet-like sheet is continuously fed out. By obtaining the structure of the molten sheet 150 by the extrusion molding method as described above, the sheet thickness of the formed conveyor belt 1 (the sheet 155 for production) can be stabilized.

These rollers can be individually rotated by a motor (driving mechanism) (not shown). By rotating these rollers, the sheet 151 can be continuously fed out. The molten sheet 150 that has been melted or softened at least on the first surface 15 side of the sheet 151 is continuously fed into this forming portion 800, the first recessed portion 12 is formed on the first surface 15 side of the molten sheet 150, and the molten sheet 150 is secondly formed. The surface 13 is flattened.

且將通過冷卻滾筒120與接觸滾筒110之間之熔融薄片150對冷卻滾筒120與後段冷卻滾筒130之間供給之，其後，對後段冷卻滾筒130與後段冷卻滾筒140之間供給之，藉此冷卻熔融薄片150。 And the molten sheet 150 between the cooling drum 120 and the contact drum 110 is supplied between the cooling drum 120 and the rear cooling drum 130, and thereafter, it is supplied between the rear cooling drum 130 and the rear cooling drum 140, thereby The molten sheet 150 is cooled.

冷卻滾筒(第1滾筒)120包含將由T字模600供給，呈熔融狀態之熔融薄片150冷卻之冷卻機構，與於其外周面，具有用來使第1凹部12成形之突起物201之第1模具部200。本實施形態中，此第1模具部200包含沿冷卻滾筒120外周面周向以等間隔方式設置之複數突起物201。於冷卻滾筒120外周面設置2個該構成之第1模具部200。藉由使熔融薄片150抵靠如此之冷卻滾筒120，於其第1面15形成第1凹部12，並冷卻熔融薄片150。 The cooling roller (first roller) 120 includes a cooling mechanism for cooling the molten sheet 150 supplied from the T-shaped die 600 in a molten state, and a first mold having a projection 201 on the outer peripheral surface for forming the first recessed portion 12. Department 200. In the present embodiment, the first mold part 200 includes a plurality of protrusions 201 provided at regular intervals along the circumferential direction of the outer peripheral surface of the cooling drum 120. On the outer peripheral surface of the cooling drum 120, two first mold portions 200 having this structure are provided. By causing the molten sheet 150 to abut against such a cooling drum 120, a first recessed portion 12 is formed on the first surface 15 thereof, and the molten sheet 150 is cooled.

本實施形態中，藉由具有複數突起物201之第1模具部200構成成形模具220。 In the present embodiment, the forming die 220 is configured by the first die portion 200 having a plurality of protrusions 201.

接觸滾筒(第2滾筒)110係外周面具有平滑性之滾筒，與冷卻滾筒(第1滾筒)120對向配置。藉由對如此之接觸滾筒110與冷卻滾筒120之間供給熔融薄片150，熔融薄片150第2面13平坦化。 The contact roller (second roller) 110 is a roller having a smooth outer peripheral surface, and is opposed to the cooling roller (first roller) 120. By supplying the molten sheet 150 between the contact drum 110 and the cooling drum 120 in this manner, the second surface 13 of the molten sheet 150 is flattened.

後段冷卻滾筒130、140皆具有冷卻熔融薄片150之冷卻機構，配置於接觸滾筒110及冷卻滾筒120後段。又，本實施形態中，後段冷卻滾筒140配置於較後段冷卻滾筒130更後段。更詳細而言，後段冷卻滾筒130與冷卻滾筒120對向配置，且後段冷卻滾筒140與後段冷卻滾筒130對向配置。藉由對如此之後段冷卻滾筒130、140供給熔融薄片150，可更確實地冷卻熔融薄片150。 The rear cooling drums 130 and 140 each have a cooling mechanism for cooling the molten sheet 150 and are arranged at the rear of the contact drum 110 and the cooling drum 120. Further, in the present embodiment, the rear cooling drum 140 is disposed at a later stage than the rear cooling drum 130. More specifically, the rear-stage cooling drum 130 and the cooling drum 120 are arranged to face each other, and the rear-stage cooling drum 140 and the rear-stage cooling drum 130 are arranged to face each other. By supplying the molten sheet 150 to the subsequent cooling rollers 130 and 140, the molten sheet 150 can be cooled more reliably.

又，本實施形態中，配置接觸滾筒110、冷卻滾筒120及後段冷卻滾筒130、140，俾此等滾筒中心搭載於一直線上。藉由如此配置滾筒，熔融薄片150第1面15可抵接冷卻滾筒120直到冷卻滾筒120旋轉180°，熔融薄片150第2面13可抵接後段冷卻滾筒130直到後段冷卻滾筒130旋轉180°， 熔融薄片150第1面15可抵接後段冷卻滾筒140直到後段冷卻滾筒140旋轉90°。藉此，可在熔融薄片150第1面15及第2面13交互抵接各冷卻滾筒120、130、140之狀態下冷卻熔融薄片150，故可確實防止於第1面15或第2面13側發生翹曲之狀態下冷卻熔融薄片150。 In this embodiment, the contact roller 110, the cooling roller 120, and the rear-stage cooling rollers 130 and 140 are arranged, and these roller centers are mounted on a straight line. By arranging the rollers in this way, the first surface 15 of the molten sheet 150 can contact the cooling roller 120 until the cooling roller 120 rotates 180 °, and the second surface 13 of the molten sheet 150 can contact the rear cooling roller 130 until the rear cooling roller 130 rotates 180 ° The first surface 15 of the molten sheet 150 may abut the rear cooling drum 140 until the rear cooling drum 140 rotates 90 °. With this, the molten sheet 150 can be cooled in a state where the first surface 15 and the second surface 13 of the molten sheet 150 abut on each of the cooling rollers 120, 130, and 140 alternately, so that it can be reliably prevented from being on the first surface 15 or the second surface 13. The molten sheet 150 is cooled with the side warped.

又，本實施形態中，雖已說明關於冷卻滾筒120具有冷卻機構，接觸滾筒110無冷卻機構之情形，但不由此情形限定，只要冷卻滾筒120及接觸滾筒110中至少一方具有冷卻機構即可，可接觸滾筒110具有冷卻機構，冷卻滾筒120無冷卻機構，亦可冷卻滾筒120與接觸滾筒110雙方皆具有冷卻機構。 In this embodiment, the case where the cooling drum 120 has a cooling mechanism and the contact drum 110 does not have a cooling mechanism has been described, but it is not limited to this case, as long as at least one of the cooling drum 120 and the contact drum 110 has a cooling mechanism, The accessible roller 110 has a cooling mechanism, and the cooling roller 120 has no cooling mechanism, and both the cooling roller 120 and the contact roller 110 have a cooling mechanism.

<運送帶製作用薄片之製造方法> <Manufacturing method of sheet for making conveyor belt>

藉由使用如以上之運送帶製作用薄片製造裝置500之運送帶製作用薄片之製造方法，可製造第1形態例之製作用薄片155。 According to the manufacturing method of the sheet for manufacturing a conveyor belt using the sheet manufacturing apparatus 500 for manufacturing a conveyor belt as described above, the manufacturing sheet 155 of the first embodiment can be manufactured.

運送帶製作用薄片之製造方法包含將作為呈帶狀之薄片之熔融狀態或軟化狀態之熔融薄片150擠出之擠製程序，與於薄片151第1面15使第1凹部12成形之成形程序。 The method for manufacturing a sheet for producing a conveyor belt includes an extrusion process of extruding a molten sheet 150 in a molten state or a softened state as a sheet-like sheet, and a forming process of forming the first recessed portion 12 on the first surface 15 of the sheet 151 .

以下，詳述關於用來製造製作用薄片155之各程序。 Hereinafter, each procedure for manufacturing the manufacturing sheet 155 will be described in detail.

〔A〕首先，將作為呈帶狀之薄片之熔融狀態或軟化狀態之熔融薄片150擠出之(擠製程序)。 [A] First, a molten sheet 150 which is a molten state or a softened state of a sheet-like sheet is extruded (extrusion process).

此擠製程序中，藉由將構成前述製作用薄片155(運送帶1)之樹脂呈熔融狀態之熔融樹脂自T字模600具有之開口部601擠出，將作為呈帶狀之薄片之熔融狀態或軟化狀態之熔融薄片150連續送出。 In this extrusion process, the molten resin constituting the resin 155 (conveying belt 1) constituting the sheet for production mentioned above is melted from the opening portion 601 provided in the T-shaped die 600, and is melted as a sheet in the shape of a belt. The molten sheet 150 in a softened state is continuously fed out.

換言之，將熔融狀態或軟化狀態之熔融薄片150自開口部601擠出，以擠製成形法成膜。 In other words, the molten sheet 150 in a molten state or a softened state is extruded from the opening portion 601 and formed into a film by extrusion.

〔B〕其次，於薄片151第1面15使第1凹部12成形(成形程序)。 [B] Next, the first recessed portion 12 is formed on the first surface 15 of the sheet 151 (forming process).

藉由對接觸滾筒110與冷卻滾筒120之間供給熔融薄片150進行此成形程序。 This forming process is performed by supplying the molten sheet 150 between the contact drum 110 and the cooling drum 120.

此時，冷卻滾筒120外周面(外周)包含具有複數突起物201而呈滾筒狀之第1模具部200。配置該突起物201，俾沿冷卻滾筒120周向以等間隔方式排列。因此，於熔融薄片150第1面15，複數對應突起物201之形狀之第1凹部12沿薄片151之供給方向亦即薄片151之長邊方向以等間隔方式形成。 At this time, the outer peripheral surface (outer periphery) of the cooling drum 120 includes a first mold part 200 having a plurality of protrusions 201 and having a drum shape. The protrusions 201 are arranged, and the ridges are arranged at equal intervals in the circumferential direction of the cooling drum 120. Therefore, on the first surface 15 of the molten sheet 150, a plurality of first recesses 12 corresponding to the shape of the protrusion 201 are formed at regular intervals along the supply direction of the sheet 151, that is, the long side direction of the sheet 151.

如此，於本程序〔B〕，為使第1凹部12成形使用冷卻滾筒120所具備之具有突起物201之第1模具部200。 In this way, in this procedure [B], the first mold portion 200 having the protrusion 201 provided in the cooling drum 120 is used to form the first recessed portion 12.

且接觸滾筒110外周面呈具有平滑性之滾筒狀，故熔融薄片150第2面13因抵靠具有平滑性之接觸滾筒110外周面而平坦化。 In addition, the outer peripheral surface of the contact roller 110 has a smooth roller shape. Therefore, the second surface 13 of the molten sheet 150 is flattened against the outer peripheral surface of the contact roller 110 having smoothness.

如此，於本程序〔B〕，為使第2面13平坦化使用接觸滾筒110。 In this way, in this procedure [B], the contact roller 110 is used to flatten the second surface 13.

〔C〕其次，使薄片151冷卻(冷卻程序)。 [C] Next, the sheet 151 is cooled (cooling procedure).

將熔融薄片150對冷卻滾筒120與後段冷卻滾筒130之間供給之，其後，對後段冷卻滾筒130與後段冷卻滾筒140之間供給之，藉此進行此冷卻程序。 The molten sheet 150 is supplied between the cooling drum 120 and the rear cooling drum 130, and thereafter, is supplied between the cooling drum 130 and the rear cooling drum 140, thereby performing this cooling process.

藉此，熔融薄片150中，熔融薄片150第1面15抵接冷卻滾筒120直到冷卻滾筒120旋轉180°，熔融薄片150第2面13抵接後段冷卻滾筒130，直到後段冷卻滾筒130旋轉180°，熔融薄片150第1面15抵接後段冷卻滾筒140，直到後段冷卻滾筒140旋轉90°。 Thereby, among the molten sheets 150, the first surface 15 of the molten sheet 150 abuts the cooling drum 120 until the cooling drum 120 rotates 180 °, and the second surface 13 of the molten sheet 150 abuts the rear cooling drum 130 until the subsequent cooling drum 130 rotates 180 ° The first surface 15 of the molten sheet 150 abuts the rear cooling drum 140 until the rear cooling drum 140 rotates 90 °.

在此，本實施形態中，冷卻滾筒120、後段冷卻滾筒130及後段冷卻滾筒140皆具有冷卻機構，故如上述，因熔融薄片150與各滾筒120、130、 140抵接(接觸)，於第1面15形成第1凹部12之熔融薄片150被冷卻。其結果，獲得於第1面15第1凹部12成形之薄片151。 Here, in this embodiment, the cooling drum 120, the rear cooling drum 130, and the rear cooling drum 140 each have a cooling mechanism. Therefore, as described above, the molten sheet 150 and each of the drums 120, 130, and 140 abuts (contacts), and the molten sheet 150 forming the first recessed portion 12 on the first surface 15 is cooled. As a result, a sheet 151 formed on the first surface 15 and the first recessed portion 12 is obtained.

又，本實施形態中，可在熔融薄片150第1面15及第2面13交互抵接各冷卻滾筒120、130、140之狀態下冷卻熔融薄片150。因此，可確實防止於第1面15或第2面13側發生翹曲之狀態下冷卻熔融薄片150。 In the present embodiment, the molten sheet 150 can be cooled in a state where the first surface 15 and the second surface 13 of the molten sheet 150 alternately contact each of the cooling rollers 120, 130, and 140. Therefore, the molten sheet 150 can be reliably prevented from being cooled in a state where warpage occurs on the first surface 15 or the second surface 13 side.

如以上，於本程序〔C〕，為冷卻熔融薄片150使用具有冷卻機構之各冷卻滾筒120、130、140。 As described above, in this procedure [C], each of the cooling drums 120, 130, and 140 having a cooling mechanism is used to cool the molten sheet 150.

〔D〕其次，於第1凹部12成形之薄片151，形成進給孔11(進給孔形成程序)。 [D] Next, the sheet 151 formed in the first recessed portion 12 forms a feed hole 11 (feed hole forming process).

藉此，可獲得具有第1凹部12與進給孔11之製作用薄片155。 Thereby, the manufacturing sheet 155 which has the 1st recessed part 12 and the feed hole 11 is obtained.

又，例如藉由使用具有對應進給孔11之形狀之頭部之衝壓機衝壓薄片151應形成進給孔11之位置，可形成如此之進給孔11。 In addition, such a feed hole 11 can be formed by punching the sheet 151 at a position where the feed hole 11 should be formed using a punch having a head corresponding to the shape of the feed hole 11.

且進給孔11之形成不需如本程序〔D〕，在第1凹部12成形後進行，亦可例如於該成形程序〔B〕，與第1凹部12之成形一併進行。 In addition, the formation of the feed hole 11 need not be performed after the first concave portion 12 is formed as in this procedure [D], but may be performed together with the formation of the first concave portion 12 in the forming procedure [B], for example.

且不使用進給孔而實施將電子零件對表面安裝機喂料時，可省略此進給孔11之形成程序。 When feeding electronic components to a surface mounter without using a feeding hole, the forming process of the feeding hole 11 can be omitted.

〔E〕其次，將獲得之製作用薄片155以第1面15或第2面13為捲筒(芯材)側捲繞之(捲繞程序)。 [E] Next, the obtained production sheet 155 is wound with the first surface 15 or the second surface 13 as the roll (core material) side (winding procedure).

藉由如此將製作用薄片155於捲筒捲繞之，可對製作用薄片155保管時及輸送時之省空間化有所貢獻。 By winding the production sheet 155 on a roll in this way, it is possible to contribute to space saving during storage and transportation of the production sheet 155.

又，保管時及輸送時製作用薄片155之形態不限於捲繞於捲筒，例如，亦可將呈帶狀之製作用薄片155於其途中沿寬方向裁斷而使其呈細長狀，以細長狀之製作用薄片155重疊之狀態保管並輸送。 In addition, the form of the production sheet 155 during storage and transport is not limited to being wound on a roll, and for example, the production sheet 155 having a band shape may be cut in the middle in a wide direction to be elongated and elongated. The shaped production sheet 155 is stored and conveyed in an overlapping state.

如以上，在捲繞於捲筒之狀態下製造製作用薄片155。 As described above, the production sheet 155 is manufactured in a state of being wound on a roll.

又，在本程序〔E〕前，亦可先使所獲得之製作用薄片155包含1對排成1列之複數第1凹部12與排成1列之複數進給孔11，沿製作用薄片155之長邊方向，以既定寬使製作用薄片155開縫(切斷)。藉此，可獲得2個運送帶1，於本程序〔E〕，可製造2個捲繞於捲筒之狀態之運送帶1。如此使製作用薄片155以既定寬開縫而獲得運送帶1時，藉由使製作用薄片155以既定寬開縫者構成切斷部，製造電子零件收納用運送帶之本發明之運送帶製造裝置500除薄片供給部700與成形部800外，更具有該切斷部。 Before the procedure [E], the obtained manufacturing sheet 155 may include a pair of a plurality of first recesses 12 arranged in a row and a plurality of feeding holes 11 arranged in a row. In the longitudinal direction of 155, the production sheet 155 is slit (cut) with a predetermined width. Thereby, two conveyer belts 1 can be obtained, and in this procedure [E], two conveyer belts 1 wound on a roll can be manufactured. In this way, when the production sheet 155 is slit with a predetermined width to obtain the conveyor belt 1, the production sheet 155 is formed with a predetermined width slit to form a cutting section, and the conveyor belt manufacturing of the present invention is to manufacture a conveyor belt for electronic parts storage. The apparatus 500 includes the cutting portion in addition to the sheet supply portion 700 and the forming portion 800.

<<第14實施形態>> << 14th Embodiment >>

其次，說明關於第14實施形態之運送帶製作用薄片製造裝置500。 Next, a sheet manufacturing apparatus 500 for producing a conveyor belt according to the fourteenth embodiment will be described.

圖33係顯示本發明之運送帶製作用薄片製造裝置之第14實施形態之縱剖面圖。 Fig. 33 is a longitudinal sectional view showing a fourteenth embodiment of the sheet manufacturing apparatus for producing a conveyor belt of the present invention.

以下，說明與前述第1實施形態之運送帶製作用薄片製造裝置500之相異點，就相同事項，省略其說明。 Hereinafter, the differences from the sheet manufacturing apparatus 500 for producing a conveyor belt according to the first embodiment will be described. The same matters will be omitted, and descriptions thereof will be omitted.

此第14實施形態之運送帶製作用薄片製造裝置500中，薄片供給部700不以擠製成形部構成，代之以加熱帶狀薄片，使該薄片至少第1面15側呈熔融狀態或軟化狀態供給之加熱部。 In the sheet manufacturing apparatus 500 for producing a conveyor belt according to the fourteenth embodiment, the sheet supply section 700 is not configured as an extruded section, but is instead heated by a belt-shaped sheet to make the sheet at least on the first surface 15 side in a molten state or softened. State-provided heating section.

亦即，本實施形態之運送帶製作用薄片製造裝置500不具有T字模600，代之以包含滾子156與頭部750。 That is, the sheet manufacturing apparatus 500 for producing a conveyor belt according to this embodiment does not include a T-shaped die 600 and instead includes a roller 156 and a head 750.

滾子156係送出帶狀薄片151之送出機構。於此滾子156捲繞薄片151。 滾子156可藉由不圖示之馬達(驅動機構)旋轉，藉由滾子156旋轉，薄片151可自滾子156連續送出。 The roller 156 is a feeding mechanism for feeding the band-shaped sheet 151. Here, the roller 156 winds the sheet 151. The roller 156 can be rotated by a motor (driving mechanism) (not shown), and the roller 156 can rotate, and the sheet 151 can be continuously sent out from the roller 156.

且頭部750係自其開口部751吹出加熱之熱風之加熱機構。頭部750經配置於滾子156與冷卻滾筒120之間，藉由對自滾子156被送出之薄片151第1面15吹送加熱之熱風，可熔融或軟化薄片151至少第1面15側。 The head 750 is a heating mechanism that blows hot air from the opening 751 of the head. The head 750 is disposed between the roller 156 and the cooling drum 120, and blows heated hot air to the first surface 15 of the sheet 151 sent out from the roller 156 to melt or soften at least the first surface 15 side of the sheet 151.

又，頭部750不限於如圖33，自開口部751對第1面15吹送加熱之熱風。例如亦可使加熱之熱板靠緊第1面15。亦即，加熱機構只要可加熱薄片151，使其至少第1面15側熔融或軟化，亦可係任何構成。 The head 750 is not limited to the one shown in FIG. 33, and hot air is blown from the opening 751 to the first surface 15. For example, the heated hot plate may be brought into close contact with the first surface 15. That is, the heating mechanism may have any structure as long as it can heat the sheet 151 to melt or soften at least the first surface 15 side.

又，關於對薄片151吹送熱風之程度，亦即薄片151之加熱程度，只要第1面15側軟化至抵緊第1模具部200之際，於薄片151第1面15形成第1凹部12之程度即可，第1面15側未必需熔融。且包含第2面13側之整體亦不需軟化或熔融。 In addition, regarding the degree of blowing hot air to the sheet 151, that is, the degree of heating of the sheet 151, as long as the first surface 15 side is softened to abut the first mold part 200, the first recess 15 of the sheet 151 is formed on the first surface 15 The degree is sufficient, and it is not necessary to melt the first surface 15 side. Moreover, the whole including the side of the second surface 13 does not need to be softened or melted.

如此之本實施形態之運送帶製作用薄片製造裝置500中，藉由滾子156與頭部750構成加熱部。藉由此加熱部，可構成供給至少第1面15側呈熔融狀態或軟化狀態之帶狀薄片之薄片供給部700。 In such a sheet manufacturing apparatus 500 for producing a conveyor belt according to this embodiment, the roller 156 and the head 750 constitute a heating section. With this heating section, a sheet supply section 700 for supplying a strip-shaped sheet in a molten state or a softened state on at least the first surface 15 side can be configured.

該構成之本實施形態之運送帶製作用薄片製造裝置500中，首先，藉由不圖示之馬達之驅動，使滾子156旋轉，將捲繞於滾子156之薄片151對接觸滾筒110與冷卻滾筒120之間連續送出(供給)。 In the sheet manufacturing apparatus 500 for producing a conveyor belt of this embodiment having the above configuration, first, a roller 156 is rotated by driving of a motor (not shown), and the sheet 151 wound on the roller 156 is brought into contact with the rollers 110 and 110. The cooling drum 120 is continuously sent out (supplied).

接著，於滾子156與冷卻滾筒120途中，自頭部750之開口部751對薄片151第1面15吹送加熱之熱風。藉此，薄片151至少第1面15側熔融或軟化，其結果，薄片151於接觸滾筒110與冷卻滾筒120之間，作為至少第1面15側呈熔融或軟化狀態之熔融薄片150被送出。 Next, in the middle of the roller 156 and the cooling drum 120, heated hot air is blown from the opening 751 of the head 750 to the first surface 15 of the sheet 151. As a result, the sheet 151 is melted or softened at least on the first surface 15 side. As a result, the sheet 151 is sent out between the contact drum 110 and the cooling drum 120 as a molten sheet 150 in a molten or softened state on at least the first surface 15 side.

又，本實施形態中，捲繞於滾子156而呈帶狀(長條狀)之薄片151 雖於接觸滾筒110與冷卻滾筒120之間被送出，但送出之薄片151不由該構成限定。例如，亦可呈細長狀預先裁斷呈帶狀之薄片151，亦可將此呈細長狀之薄片151朝接觸滾筒110與冷卻滾筒120之間送出。此時，運送帶製作用薄片製造裝置500中，省略滾子156之配置，加熱部由頭部750構成。 In the present embodiment, the sheet 151 is wound around a roller 156 and has a strip-like shape (strip shape). Although it is sent out between the contact roller 110 and the cooling roller 120, the sheet | seat 151 sent out is not limited by this structure. For example, the strip-shaped sheet 151 may be cut in advance in an elongated shape, and the strip-shaped sheet 151 may be sent out between the contact roller 110 and the cooling roller 120. At this time, in the sheet manufacturing apparatus 500 for producing a conveyor belt, the arrangement of the rollers 156 is omitted, and the heating section is constituted by a head 750.

如此，即使在不以擠製成形部構成薄片供給部700，而代之以加熱部之情形下，亦可獲得與以前述第1實施形態說明者相同之效果。 As described above, even when the sheet supply unit 700 is not configured by an extruded portion and is replaced by a heating portion, the same effects as those described in the first embodiment can be obtained.

惟藉由如前述第1~13實施形態，以擠製成形部構成薄片供給部，可以一連串動作一併進行薄片151之製造與在薄片151形成第1凹部12。因此，不需預先存貨、準備開縫為必要之厚度、寬度、長度之帶狀薄片，可解決資材購入費或加工費等增加，招致高成本化之問題。 However, according to the aforementioned first to thirteenth embodiments, the sheet supply portion is formed by the extruded portion, and the sheet 151 can be manufactured in a series of operations and the first recessed portion 12 can be formed in the sheet 151. Therefore, it is not necessary to store inventory in advance, and to prepare slit-shaped strips with the necessary thickness, width, and length, which can solve the problem of increasing the purchase cost of materials or processing costs and causing high costs.

In the lengthwise direction of 155, the production sheet 155 is slit with a predetermined width, whereby two conveying belts 1 can be obtained. That is, by slitting the production sheet 155 along the imaginary line shown in FIG. 33, it is possible to manufacture two rows of one row having a pair of plural first recesses 12 and one row of the plural feeding holes 11. With 1.

於如此之運送帶製作用薄片155，在本形態例中，於具有第2凹部(位置修正用凹部)16之點，與第1形態例之製作用薄片155不同。為以後述製作用薄片155之製造方法，設置複數進給孔11，俾與複數第1凹部12平行，使用此第2凹部16。亦即，為以相對於第1凹部12優異之位置精度設置進給孔11，使用第2凹部16。 The sheet 155 for producing such a conveyor belt is different from the sheet 155 for production of the first embodiment in that the second embodiment has a second recessed portion (position-correcting recessed portion) 16. For the manufacturing method of the sheet 155 described later, a plurality of feed holes 11 are provided, and 俾 is parallel to the plurality of first recessed portions 12, and this second recessed portion 16 is used. That is, in order to provide the feed hole 11 with excellent positional accuracy with respect to the 1st recessed part 12, the 2nd recessed part 16 is used.

此第2凹部16之深度為J(mm)，運送帶製作用薄片155中第2凹部16底部之厚度為K(mm)，製作用薄片155中該第1凹部及第2凹部以外之部分之厚度為C(mm)時，宜形成第2凹部，俾大致滿足J+K=C。所謂大致滿足J+K=C係例如滿足-0.1<C-(J+K)<0.1，滿足-0.05<C-(J+K)<0.05更佳。藉由滿足該式，第2面13更平坦，可防止將運 送帶製作用薄片155捲繞於捲筒而保管時或輸送之際捲繞崩塌或捲繞鬆弛。 The depth of the second recessed portion 16 is J (mm), and the thickness of the bottom of the second recessed portion 16 in the sheet 155 for conveyor belt production is K (mm). When the thickness is C (mm), it is preferable to form a second recess, and 俾 approximately satisfies J + K = C. The so-called substantially satisfying J + K = C system satisfies, for example, -0.1 <C- (J + K) <0.1, and more preferably -0.05 <C- (J + K) <0.05. By satisfying this formula, the second surface 13 is flatter and prevents The sheet preparation sheet 155 is wound on a roll and is wound or collapsed during storage or during transportation.

且第2凹部16之深度J依運送帶製作用薄片155中該第1凹部及第2凹部以外之部分之厚度C變化。第2凹部16之深度J宜滿足C-0.15≦J≦C-0.05，C-0.13≦J≦C-0.07更佳。因第2凹部16之深度J處於該較佳範圍內，於製作用薄片155之製造方法，可收納後述位置修正用指引器及位置限制用指引器在第2凹部16中，並可確實防止於此等收納時第2凹部16裂斷。 The depth J of the second recessed portion 16 varies depending on the thickness C of a portion other than the first recessed portion and the second recessed portion in the sheet 155 for producing a conveyor belt. The depth J of the second concave portion 16 should satisfy C-0.15 ≦ J ≦ C-0.05, and more preferably C-0.13 ≦ J ≦ C-0.07. Since the depth J of the second recessed portion 16 is within the preferable range, the manufacturing method of the sheet 155 can store the position correction guide and position limiter described later in the second recessed portion 16 and can be reliably prevented from During such storage, the second recessed portion 16 is broken.

且該第2凹部16內側緣部18宜以曲率半徑在0.2mm以下之方式彎曲，在0.1mm以下更佳。因第2凹部16採取如此之構成，可增大第2凹部16與底面正交之側壁面之直線部。藉此，可防止第2凹部16側壁面自底部橫跨緣部擴張，故可確實收納位置修正用指引器及位置限制用指引器於第2凹部16內。 In addition, the inner edge portion 18 of the second recessed portion 16 is preferably bent so that the curvature radius is 0.2 mm or less, and more preferably 0.1 mm or less. Since the second recessed portion 16 adopts such a configuration, the linear portion of the side wall surface orthogonal to the bottom surface of the second recessed portion 16 can be increased. Thereby, since the side wall surface of the second recessed portion 16 can be prevented from expanding from the bottom to the edge portion, the position correction guide and the position restriction guide can be surely stored in the second recess 16.

本實施形態中，電子零件收納用運送帶之製造方法包含：加熱程序，將帶狀薄片151加熱，使薄片151至少第1面15側熔融或軟化；成形程序，於薄片151第1面15使第1凹部12成形；冷卻程序，使薄片151冷卻；及沖壓程序，於薄片151加工進給孔11。 In this embodiment, the method for manufacturing a conveyor belt for storing electronic parts includes a heating procedure, which heats the strip-shaped sheet 151 to melt or soften at least the first surface 15 side of the sheet 151; and a forming process, which is performed on the first surface 15 of the sheet 151 The first recessed portion 12 is formed; the cooling process cools the sheet 151; and the punching process processes the feed hole 11 in the sheet 151.

以下，詳述關於各程序。 Hereinafter, each program will be described in detail.

〔A〕首先，將作為呈帶狀之薄片之熔融狀態或軟化狀態之熔融薄片150擠出之(擠製程序)。 [A] First, a molten sheet 150 which is a molten state or a softened state of a sheet-like sheet is extruded (extrusion process).

此擠製程序中，藉由將構成前述製作用薄片155(運送帶1)之樹脂呈熔融狀態之熔融樹脂自T字模600具有之開口部601擠出，將作為呈帶狀之薄片之熔融狀態或軟化狀態之熔融薄片150連續送出。 In this extrusion process, the molten resin constituting the resin 155 (conveying belt 1) constituting the sheet for production mentioned above is melted from the opening portion 601 provided in the T-shaped die 600, and is melted as a sheet in the shape of a belt. The molten sheet 150 in a softened state is continuously fed out.

〔B〕其次，於薄片151第1面15使第1凹部12及第2凹部16成形(成形程序)。 [B] Next, the first concave portion 12 and the second concave portion 16 are formed on the first surface 15 of the sheet 151 (forming process).

藉由對接觸滾筒110與冷卻滾筒120之間供給熔融薄片150進行此成形程序。 This forming process is performed by supplying the molten sheet 150 between the contact drum 110 and the cooling drum 120.

冷卻滾筒120外周面(外周)具有成形模具220，成形模具220包含：第1模具部200，具有複數突起物201而呈滾筒狀；及第2模具部210，具有複數突起物211而呈滾筒狀。 The cooling drum 120 has a forming die 220 on its outer peripheral surface (outer periphery), and the forming die 220 includes a first die portion 200 having a plurality of protrusions 201 in a roll shape, and a second die portion 210 having a plurality of protrusions 211 in a roll shape. .

配置複數突起物201，俾沿冷卻滾筒120周向以等間隔方式排列，且配置複數突起物211，俾沿薄片151之短邊方向與複數突起物201平行，並沿冷卻滾筒120周向以等間隔方式排列。 A plurality of protrusions 201 are arranged, 俾 are arranged at equal intervals along the circumferential direction of the cooling drum 120, and a plurality of protrusions 211 are arranged, 俾 are parallel to the plurality of protrusions 201 along the short side direction of the sheet 151, and are uniformly arranged along the circumferential direction of the cooling drum 120. Spaced arrangement.

因此，於熔融薄片150第1面15，沿薄片151之供給方向亦即薄片151之長邊方向以等間隔方式形成複數對應突起物201之形狀之第1凹部12，且沿薄片151之長邊方向以等間隔方式形成複數對應突起物211之形狀之第2凹部16，俾沿薄片151之短邊方向與複數第1凹部12平行。 Therefore, on the first surface 15 of the molten sheet 150, the first recesses 12 corresponding to the shape of the protrusions 201 are formed at equal intervals along the feeding direction of the sheet 151, that is, the long side direction of the sheet 151, and along the long side of the sheet 151 The second recessed portions 16 corresponding to the shape of the plurality of protrusions 211 are formed at equal intervals in the direction, and the second recessed portions 16 along the short side direction of the sheet 151 are parallel to the plurality of first recessed portions 12.

如此，於本程序〔B〕，為使第1凹部12成形使用冷卻滾筒120包含之具有突起物201之第1模具部200，為使第2凹部16成形使用具有突起物211之第2模具部210。 In this way, in this procedure [B], the first mold portion 200 having the projection 201 included in the cooling drum 120 is used to form the first recessed portion 12, and the second mold portion having the projection 211 is used to form the second recessed portion 16. 210.

且接觸滾筒110外周面呈具有平滑性之滾筒狀，故熔融薄片150第2面13因抵靠具有平滑性之外周面而平坦化。 In addition, the outer peripheral surface of the contact roller 110 has a smooth roll shape, so the second surface 13 of the molten sheet 150 is flattened against the outer peripheral surface having smoothness.

如此，於本程序〔B〕，為使第2面13平坦化使用接觸滾筒110。 In this way, in this procedure [B], the contact roller 110 is used to flatten the second surface 13.

〔C〕其次，使薄片151冷卻(冷卻程序)。 [C] Next, the sheet 151 is cooled (cooling procedure).

將熔融薄片150對冷卻滾筒120與後段冷卻滾筒130之間供給之，其後，對後段冷卻滾筒130與後段冷卻滾筒140之間供給之，藉此進行此冷卻程序。 The molten sheet 150 is supplied between the cooling drum 120 and the rear cooling drum 130, and thereafter, is supplied between the cooling drum 130 and the rear cooling drum 140, thereby performing this cooling process.

藉此，熔融薄片150中，熔融薄片150第1面15抵接冷卻滾筒120，直到冷卻滾筒120旋轉180°，熔融薄片150第2面13抵接後段冷卻滾筒130，直到後段冷卻滾筒130旋轉180°，熔融薄片150第1面15抵接後段冷卻滾筒140，直到後段冷卻滾筒140旋轉90°。 Thereby, among the molten sheets 150, the first surface 15 of the molten sheet 150 abuts on the cooling drum 120 until the cooling drum 120 rotates 180 °, and the second surface 13 of the molten sheet 150 abuts on the rear cooling drum 130 until the subsequent cooling drum 130 rotates 180 °, the first surface 15 of the molten sheet 150 abuts on the rear cooling drum 140 until the rear cooling drum 140 rotates 90 °.

在此，本實施形態中，冷卻滾筒120、後段冷卻滾筒130及後段冷卻滾筒140皆具有冷卻機構，故如上述，因熔融薄片150與各滾筒120、130、140抵接(接觸)，於第1面15形成第1凹部12及第2凹部16之熔融薄片150被冷卻。其結果，可獲得第1凹部12及第2凹部16成形於第1面15之薄片151。 Here, in this embodiment, the cooling drum 120, the rear cooling drum 130, and the rear cooling drum 140 each have a cooling mechanism. Therefore, as described above, the molten sheet 150 abuts (contacts) with each of the drums 120, 130, and 140. The molten sheet 150 forming the first recessed portion 12 and the second recessed portion 16 on one surface 15 is cooled. As a result, a sheet 151 in which the first concave portion 12 and the second concave portion 16 are formed on the first surface 15 can be obtained.

又，本實施形態中，可在熔融薄片150第1面15及第2面13交互抵接各冷卻滾筒120、130、140之狀態下冷卻熔融薄片150。因此，可確實防止於第1面15或第2面13側發生翹曲之狀態下冷卻熔融薄片150。 In the present embodiment, the molten sheet 150 can be cooled in a state where the first surface 15 and the second surface 13 of the molten sheet 150 alternately contact each of the cooling rollers 120, 130, and 140. Therefore, the molten sheet 150 can be reliably prevented from being cooled in a state where warpage occurs on the first surface 15 or the second surface 13 side.

如以上，於本程序〔C〕，為冷卻熔融薄片150使用具有冷卻機構之各冷卻滾筒120、130、140。 As described above, in this procedure [C], each of the cooling drums 120, 130, and 140 having a cooling mechanism is used to cool the molten sheet 150.

〔D〕其次，對第1凹部12及第2凹部16成形之薄片151加工進給孔11(沖壓程序)。 [D] Next, the feed hole 11 is processed into the sheet 151 formed by the first recessed portion 12 and the second recessed portion 16 (pressing process).

進行此進給孔11之對薄片151之加工(沖壓)時，使用運送帶製作用薄片製造裝置500具有之沖壓模具900。 When the sheet 151 is processed (punched) in the feed hole 11, a punching die 900 included in the sheet manufacturing apparatus 500 for producing a conveyor belt is used.

此時，以沖壓模具900對薄片151之進給孔11之第1次沖壓與第2次以後之沖壓中，沖壓模具900具有之各部用途不同。因此，於以下，首先，說明關於以沖壓模具900進行之第1次沖壓，接著，說明關於第2次沖壓。 At this time, in the first punching of the feed hole 11 of the sheet 151 by the punching die 900 and the second and subsequent punches, the parts of the punching die 900 have different uses. Therefore, in the following, first, the first punching performed by the punching die 900 will be described, and then, the second punching will be described.

<<第1次沖壓>> << The first punching >>

首先，進行以沖壓模具900對薄片151之進給孔11之第1次沖壓，亦即使用沖壓工具921衝壓薄片151之最初之第1次。第1次沖壓中，沖壓模具900具有之各部對應第1凹部12及第2凹部16成形之薄片151各部，如以下配置。 First, the first punching of the feed hole 11 of the sheet 151 with the punching die 900 is performed, that is, the first first punching of the sheet 151 using the punching tool 921. In the first press, each part of the punching die 900 corresponds to each part of the sheet 151 formed by the first recessed part 12 and the second recessed part 16 and is arranged as follows.

亦即，如圖39(a)所示，位置修正用指引器932在自薄片151上側觀 察薄片151時，沖壓工具921具有之突起物922之薄片151前進方向入口側與出口側各外側，對應第2凹部16，將其前端部***第2凹部16內。 That is, as shown in FIG. 39 (a), the position correction guide 932 is viewed from above the sheet 151. When inspecting the sheet 151, the sheet 151 of the protrusion 922 provided in the punching tool 921 is located on the outside of the inlet side and the outlet side of the advancement direction, corresponding to the second recessed portion 16, and the front end portion is inserted into the second recessed portion 16.

且位置限制用指引器923於位置修正用指引器932之薄片151前進方向入口側與出口側各外側，亦即，沖壓工具921具有之突起物922之薄片151前進方向入口側與出口側各外側，對應第2凹部16，將其前端部***第2凹部16內。 In addition, the position restricting guide 923 is located on the outside of the entrance side and the exit side of the sheet 151 in the advancing direction of the position correcting guide 932, that is, the entrance 151 and the exit side of the sheet 151 of the protrusion 922 provided in the punching tool 921 , Corresponding to the second recessed portion 16, the tip portion is inserted into the second recessed portion 16.

且指引器銷931於沖壓工具921具有之突起物922之薄片151前進方向出口側，對應薄片151因第2次以後之沖壓形成進給孔11之位置，將其前端部抵接薄片151。 And the guide pin 931 is on the exit side of the sheet 151 of the protrusion 922 provided in the punching tool 921 in the advancing direction of the sheet 151, and the tip of the sheet 151 abuts the sheet 151 corresponding to the position of the feed hole 11 formed by the second and subsequent punching.

以下，依序說明關於使用如此配置各部之沖壓模具900，形成進給孔11之方法。 Hereinafter, a method of forming the feed hole 11 using the punching die 900 in which the parts are arranged in this manner will be described in order.

〔D-1a〕首先，將如圖40(a)所示形成第1凹部12及第2凹部16之薄片151自薄片151前進方向(搬運方向)入口側(上游側)朝出口側(下游側)搬運，藉此在支持台950上，亦即，支持台950與沖壓頭910之間，搬運(供給)薄片151(參照圖41(a))。 [D-1a] First, as shown in FIG. 40 (a), the sheet 151 forming the first recessed portion 12 and the second recessed portion 16 is moved from the entrance side (upstream side) of the sheet 151 in the advancing direction (conveying direction) to the exit side (downstream side). ), Thereby carrying (supplying) the sheet 151 on the support table 950, that is, between the support table 950 and the punch 910 (see FIG. 41 (a)).

〔D-2a〕接著，使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，使位置限制用指引器923沿薄片151之厚度方向朝下側移動，藉此將位置限制用指引器923前端部***第2凹部16內(參照圖41(b))。 [D-2a] Next, the punching head 910 is moved downward in the thickness direction of the sheet 151, that is, the position restricting guide 923 is moved downward in the thickness direction of the sheet 151, thereby guiding the position restricting The distal end portion of the holder 923 is inserted into the second recessed portion 16 (see FIG. 41 (b)).

藉此，第2凹部16因位置限制用指引器923被限制位置。 Thereby, the position of the second recessed portion 16 is restricted by the position restricting guide 923.

在此，本程序中，位置限制用指引器923前端部雖***第2凹部16，但位置限制用指引器923前端部之形狀，與第2凹部16之形狀中可舉出例如以下關係者。 Here, although the front end portion of the position restriction guide 923 is inserted into the second recessed portion 16 in this procedure, the shape of the front end portion of the position restriction guide 923 and the shape of the second recessed portion 16 include, for example, the following relationships.

亦即，首先，如圖45(A1)所示，可舉出下列者：位置限制用指引器 923前端部長度為P(mm)，前端部寬為Q(mm)時，前端部呈前端部寬Q自基端朝前端一定之形狀，如對應此形狀，第2凹部16之深度為J(mm)，底部之厚度為K(mm)，寬為L(mm)，第1凹部及第2凹部以外之部分之厚度為C(mm)時，第2凹部16呈第2凹部16之寬L沿深度(厚度)方向一定之形狀。 That is, first, as shown in FIG. 45 (A1), the following can be cited: a position-limiting director 923 When the length of the front end portion is P (mm) and the width of the front end portion is Q (mm), the front end portion has a shape in which the front end width Q is constant from the base end to the front end. If corresponding to this shape, the depth of the second recess 16 is J ( mm), the thickness at the bottom is K (mm), the width is L (mm), and when the thickness of the portion other than the first and second recesses is C (mm), the second recess 16 has the width L of the second recess 16 A certain shape along the depth (thickness) direction.

此時，宜形成位置限制用指引器932前端部之形狀與第2凹部16之形狀，俾滿足J<P，並滿足0<L-Q≦0.06，更宜形成為滿足0<L-Q≦0.03。 At this time, it is preferable to form the shape of the front end portion of the position-limiting guide 932 and the shape of the second recessed portion 16 so that 俾 satisfies J <P and 0 <L-Q ≦ 0.06, and more preferably forms 0 <L-Q ≦ 0.03.

且V=(L-Q)/2，如後述，第2凹部16由位置修正用指引器932限制位置之最大量為U(mm)，位置修正用指引器932前端部前端側寬為N(mm)，U=(L-N)/2時，宜形成為滿足V<U，滿足(L-Q)/2<(L-N)/2，更滿足Q>N。 And V = (LQ) / 2. As described later, the maximum position of the second recessed portion 16 by the position correction guide 932 is U (mm), and the width of the front end side of the front end portion of the position correction guide 932 is N (mm). When U = (LN) / 2, it should be formed to satisfy V <U, (LQ) / 2 <(LN) / 2, and more preferably Q> N.

形成位置限制用指引器932前端部之形狀與第2凹部16之形狀，俾滿足如此之關係，藉此如圖44(A2)、(A3)所示，於第2凹部16內，將對應其形狀之位置限制用指引器923前端部***，以如後述可於第2凹部16內，將對應其形狀之位置修正用指引器932前端部在位置不偏離之情形下，以更優異之精度收納之。 The shape of the front end portion of the position-limiting guide 932 and the shape of the second recessed portion 16 are formed so as to satisfy such a relationship. As shown in FIGS. 44 (A2) and (A3), the second recessed portion 16 corresponds to the shape of the second recessed portion 16. The front end portion of the shape position restricting guide 923 is inserted, so that the front end portion of the position correction guide 932 corresponding to the shape can be stored in the second recess 16 as described later, and the position can be stored with better accuracy. Of it.

且如圖45(B1)所示，可舉出下列者：位置限制用指引器923前端部長度為P(mm)，前端部寬為Q(mm)時，前端部呈前端部寬Q自基端朝前端縮短(減小)之形狀，如對應此形狀，第2凹部16之深度為J(mm)，底部之厚度為K(mm)，寬為L(mm)，第1凹部及第2凹部以外之部分之厚度為C(mm)時，第2凹部16呈第2凹部16之寬L沿深度(厚度)方向朝底部側縮短之形狀。 And as shown in FIG. 45 (B1), the following can be cited: When the length of the front end portion of the position restricting guide 923 is P (mm) and the width of the front end portion is Q (mm), the front end portion has a front end width Q from the base The shape that is shortened (decreased) toward the front end. If corresponding to this shape, the depth of the second recess 16 is J (mm), the thickness of the bottom is K (mm), the width is L (mm), the first recess and the second When the thickness of the portion other than the recessed portion is C (mm), the second recessed portion 16 has a shape in which the width L of the second recessed portion 16 is shortened toward the bottom side in the depth (thickness) direction.

此時，前端部中心軸與前端部側面構成之角度為β(°)，薄片151之厚度方向與第2凹部16之內周面構成之角度為θ(°)時，宜形成位置限制用指引器932前端部之形狀與第2凹部16之形狀，俾滿足β=θ，10°≦θ≦30°， 滿足L≦Q。 At this time, when the angle formed by the central axis of the front end portion and the side surface of the front end portion is β (°), and the angle formed by the thickness direction of the sheet 151 and the inner peripheral surface of the second recessed portion 16 is θ (°), a guide for position limitation should be formed. The shape of the front end of the device 932 and the shape of the second concave portion 16 satisfy 俾 = θ, 10 ° ≦ θ ≦ 30 °, Meet L ≦ Q.

且如圖45(B2)所示，沿薄片151之厚度方向，位置限制用指引器923前端部與薄片151第1面15一致之際前端部中心軸與第2凹部16前端部之位置偏離之大小為V(mm)時，V可以V=L/2+J×Tanθ-Q/2=J×Tanθ-(Q-L)/2表示。此時，宜形成位置限制用指引器932前端部之形狀與第2凹部16之形狀，俾滿足0.03<V<0.5。 Further, as shown in FIG. 45 (B2), along the thickness direction of the sheet 151, when the front end portion of the position restricting guide 923 coincides with the first surface 15 of the sheet 151, the position of the center axis of the front end portion deviates from the position of the front end portion of the second recess portion 16. When the size is V (mm), V can be expressed as V = L / 2 + J × Tanθ-Q / 2 = J × Tanθ- (QL) / 2. At this time, it is desirable to form the shape of the front end portion of the position-limiting guide 932 and the shape of the second recessed portion 16 so that 俾 satisfies 0.03 <V <0.5.

且如圖45(B3)所示，對應第2凹部16而***位置限制用指引器923前端部之際，***第2凹部16內之前端部之深度(大小)為δ(mm)時，δ可以δ=J-(Q-L)/(2×Tanθ)表示。此時，宜形成位置限制用指引器932前端部之形狀與第2凹部16之形狀，俾滿足δ≧0.15。且此時，第2凹部16中心軸，與位置限制用指引器923中心軸之位置偏離之大小為V(mm)之際，V可以V=0表示。 As shown in FIG. 45 (B3), when the front end portion of the position limiting guide 923 is inserted corresponding to the second recessed portion 16, when the depth (size) of the front end portion inserted into the second recessed portion 16 is δ (mm), δ It can be expressed by δ = J- (QL) / (2 × Tanθ). At this time, it is preferable to form the shape of the front end portion of the position-limiting guide 932 and the shape of the second recessed portion 16 so that 俾 satisfies δ ≧ 0.15. At this time, when the positional deviation of the central axis of the second recessed portion 16 from the central axis of the position-limiting guide 923 is V (mm), V can be expressed as V = 0.

藉由滿足如此之關係，如圖45(B2)、(B3)所示，於第2凹部16內，將對應其形狀之位置限制用指引器923前端部***，藉此如後述可於第2凹部16內，將對應其形狀之位置修正用指引器932前端部在位置不偏離之情形下，以更優異之精度收納之。 By satisfying such a relationship, as shown in FIGS. 45 (B2) and (B3), the front end portion of the position-limiting guide 923 corresponding to the shape is inserted into the second recessed portion 16, so that it can be used in the second portion as described later. The front end portion of the position correction guide 932 corresponding to the shape of the recessed portion 16 is accommodated in the recessed portion 16 with higher accuracy without being deviated.

〔D-3a〕接著，更使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，使指引器銷931沿薄片151之厚度方向朝下側移動，藉此使指引器銷931前端部抵接薄片151第1面15(參照圖41(c))。 [D-3a] Next, the punch 910 is further moved downward in the thickness direction of the sheet 151, that is, the pointer pin 931 is moved downward in the thickness direction of the sheet 151, thereby leading the tip of the pointer pin 931 Part abutment sheet 151 first surface 15 (see FIG. 41 (c)).

此時，指引器銷931其基端側部因彈簧材933偏壓，故可防止薄片151第1面15被撐破。 At this time, the base pin side of the guide pin 931 is biased by the spring material 933, so that the first surface 15 of the sheet 151 can be prevented from being broken.

〔D-4a〕接著，更使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，使位置修正用指引器932沿薄片151之厚度方向朝下側移動，藉此將位置修正用指引器932前端部***第2凹部16內(參照圖41(d))。 [D-4a] Next, the punch 910 is further moved downward in the thickness direction of the sheet 151, that is, the position correction guide 932 is moved downward in the thickness direction of the sheet 151, thereby moving the position correction The front end portion of the guide 932 is inserted into the second recessed portion 16 (see FIG. 41 (d)).

藉此，第2凹部16由位置修正用指引器932限制位置。 Thereby, the position of the second recessed portion 16 is restricted by the position correction guide 932.

又，依如此之順序實施之以位置限制用指引器923及位置修正用指引器932限制位置時，第2凹部16由位置修正用指引器932限制位置之最大量，亦即，沿薄片151之厚度方向，位置修正用指引器932前端部與薄片151第1面15一致之際前端部之中心軸，與第2凹部16前端部之位置偏離之大小為U(mm)，第2凹部16中心軸與位置限制用指引器923中心軸之位置偏離最大量為V(mm)時，宜滿足V≦U，滿足0≦U-V≦0.5。藉由滿足該關係，呈實施以位置限制用指引器923限制位置後，以位置修正用指引器932限制位置之構成，藉此於後程序〔D-6a〕，可使進給孔11以更優異之位置精度形成於薄片151。 In addition, when the position is restricted by the position restriction guide 923 and the position correction guide 932 in this order, the maximum amount of the position of the second recess 16 is restricted by the position correction guide 932, that is, along the sheet 151. In the thickness direction, when the front end portion of the position correction guide 932 coincides with the first surface 15 of the sheet 151, the center axis of the front end portion is deviated from the front end portion of the second recessed portion 16 by U (mm), and the center of the second recessed portion 16 When the maximum deviation between the position of the shaft and the central axis of the position-limiting guide 923 is V (mm), it should satisfy V ≦ U and 0 ≦ UV ≦ 0.5. By satisfying this relationship, a configuration is implemented in which the position is restricted by the position restricting guide 923 and then the position is corrected by the position correcting guide 932. With the following procedure [D-6a], the feed hole 11 can be changed more The excellent position accuracy is formed in the sheet 151.

在此，本程序中，位置修正用指引器932前端部雖***第2凹部16，但位置修正用指引器932前端部之形狀，與第2凹部16之形狀中可舉出例如以下關係者。 Here, although the front end portion of the position correction guide 932 is inserted into the second recessed portion 16 in this program, examples of the shape of the front end portion of the position correction guide 932 and the shape of the second recessed portion 16 include the following.

亦即，首先，如圖46(A1)所示，可舉出下列者：位置修正用指引器932前端部長度為M(mm)，前端部前端側寬為N(mm)時，前端部呈前端部寬N自基端朝前端縮短(減小)之形狀，相對於此，第2凹部16之深度為J(mm)，底部之厚度為K(mm)，寬為L(mm)，第1凹部及第2凹部以外之部分之厚度為C(mm)時，第2凹部16呈第2凹部16之寬L沿深度(厚度)方向一定之形狀。 That is, first, as shown in FIG. 46 (A1), the following can be cited: When the length of the front end portion of the position correction guide 932 is M (mm) and the front end side width is N (mm), the front end portion is The shape of the width N of the front end is shortened (decreased) from the base end toward the front end. In contrast, the depth of the second recess 16 is J (mm), the thickness of the bottom is K (mm), and the width is L (mm). When the thickness of the portion other than the first recessed portion and the second recessed portion is C (mm), the second recessed portion 16 has a shape in which the width L of the second recessed portion 16 is constant along the depth (thickness) direction.

此時，宜形成位置修正用指引器932前端部之形狀與第2凹部16之形狀，俾滿足M=J，滿足N<L。 At this time, the shape of the front end portion of the position correction guide 932 and the shape of the second recessed portion 16 should be formed, and 俾 satisfies M = J and N <L.

且U=(L-N)/2，如後述，指引器銷931之中心軸，與進給孔11之中心軸之位置偏離之大小為W(mm)，進給孔11之內徑為R(mm)，指引器銷931之基端部側外徑為S(mm)，W=(R-S)/2時，宜形成位置修正用指引器932前端部之形狀與第2凹部16之形狀，俾滿足U>W，滿足(L-N)/2>(R-S)/2，更滿足L-N>R-S。 And U = (LN) / 2. As will be described later, the position of the center axis of the guide pin 931 from the center axis of the feed hole 11 is W (mm), and the inner diameter of the feed hole 11 is R (mm). ), When the outer diameter of the base end portion side of the guide pin 931 is S (mm), and W = (RS) / 2, the shape of the front end portion of the position correction guide 932 and the shape of the second recess 16 should be formed. U> W, satisfying (LN) / 2> (RS) / 2, and more satisfying LN> RS.

且前端部基端側寬在前端部中心軸與前端部側面構成之角度為α(°)時，可以N+2×M×Tanα表示。此時，宜形成位置修正用指引器932前端部之形狀與第2凹部16之形狀，俾滿足L+0.04≦N+2×M×Tanα≦L+0.1。 In addition, when the angle of the base end side width of the front end portion formed by the central axis of the front end portion and the side surface of the front end portion is α (°), it can be expressed by N + 2 × M × Tanα. At this time, it is preferable to form the shape of the front end portion of the position correction guide 932 and the shape of the second concave portion 16 so that 俾 satisfies L + 0.04 ≦ N + 2 × M × Tanα ≦ L + 0.1.

藉由滿足如此之關係，如圖46(A2)、(A3)所示，可於第2凹部16內，將對應其之位置修正用指引器932前端部在不偏離位置之情形下，以更優異之精度收納之。 By satisfying such a relationship, as shown in FIGS. 46 (A2) and (A3), the front end portion of the position correction guide 932 corresponding to the second recessed portion 16 can be changed in a more stable manner without deviating from the position. It is stored with excellent precision.

且如圖46(B1)所示，可舉出下列者：位置修正用指引器932前端部長度為M(mm)，前端部寬為N(mm)時，前端部呈前端部寬N自基端朝前端縮短(減小)之形狀，如對應此形狀，第2凹部16之深度為J(mm)，底部之厚度為K(mm)，寬為L(mm)，第1凹部及第2凹部以外之部分之厚度為C(mm)時，第2凹部16呈第2凹部16之寬L沿深度(厚度)方向朝底部側縮短之形狀。 As shown in FIG. 46 (B1), the following can be cited: When the length of the front end portion of the position correction guide 932 is M (mm) and the width of the front end portion is N (mm), the front end portion has a front end width N from the base The shape that is shortened (decreased) toward the front end. If corresponding to this shape, the depth of the second recess 16 is J (mm), the thickness of the bottom is K (mm), the width is L (mm), the first recess and the second When the thickness of the portion other than the recessed portion is C (mm), the second recessed portion 16 has a shape in which the width L of the second recessed portion 16 is shortened toward the bottom side in the depth (thickness) direction.

此時，前端部中心軸與前端部側面構成之角度為α(°)，薄片151之厚度方向與第2凹部16之內周面構成之角度為θ(°)時，宜形成位置修正用指引器932前端部之形狀與第2凹部16之形狀，俾滿足α=θ，10°≦θ≦30°，滿足L≦N。 At this time, when the angle formed by the central axis of the front end portion and the side surface of the front end portion is α (°), and the angle formed by the thickness direction of the sheet 151 and the inner peripheral surface of the second recessed portion 16 is θ (°), a guide for position correction should be formed. The shape of the front end portion of the device 932 and the shape of the second recessed portion 16 satisfy α = θ, 10 ° ≦ θ ≦ 30 °, and L ≦ N.

且如圖46(B2)所示，沿薄片151之厚度方向，位置修正用指引器932前端部與薄片151第1面15一致之際，前端部之中心軸，與第2凹部16前端部之位置偏離之大小，亦即，第2凹部16由位置修正用指引器932限制位置之最大量為U(mm)時，U可以U=L/2+J×Tanθ-N/2=J×Tanθ-(N-L)/2表示。此時，宜形成位置修正用指引器932前端部之形狀與第2凹部16之形狀，俾滿足0.03<U<0.5。 As shown in FIG. 46 (B2), along the thickness direction of the sheet 151, when the front end portion of the position correction guide 932 coincides with the first surface 15 of the sheet 151, the center axis of the front end portion and the front end portion of the second concave portion 16 The size of the position deviation, that is, when the maximum position of the second recessed portion 16 restricted by the position correction guide 932 is U (mm), U may be U = L / 2 + J × Tanθ-N / 2 = J × Tanθ -(NL) / 2. At this time, the shape of the front end portion of the position correction guide 932 and the shape of the second recessed portion 16 should be formed, and 俾 satisfies 0.03 <U <0.5.

且如圖46(B3)所示，對應第2凹部16而***位置修正用指引器932前端部之際，***第2凹部16內之前端部之深度(大小)為γ(mm)時， γ可以γ=J-(N-L)/(2×Tanθ)表示。此時，宜形成位置修正用指引器932前端部之形狀與第2凹部16之形狀，俾滿足γ≧0.15。且此時，第2凹部16中心軸，與位置修正用指引器932之中心軸之位置偏離之大小為U(mm)時，U可以U=0表示。 When the front end of the position correction guide 932 is inserted corresponding to the second recess 16 as shown in FIG. 46 (B3), when the depth (size) of the front end inserted into the second recess 16 is γ (mm), γ can be expressed by γ = J- (N-L) / (2 × Tanθ). At this time, it is preferable to form the shape of the front end portion of the position correction guide 932 and the shape of the second concave portion 16 so that 俾 satisfies γ ≧ 0.15. At this time, when the position of the central axis of the second recessed portion 16 from the central axis of the position correction guide 932 is U (mm), U can be expressed by U = 0.

藉由滿足如此之關係，如圖46(B2)、(B3)所示，可於第2凹部16內，將對應其形狀之位置修正用指引器932前端部在位置不偏離之情形下，以更優異之精度收納之。 By satisfying such a relationship, as shown in FIGS. 46 (B2) and (B3), the position of the front end of the position correction guide 932 corresponding to the shape in the second recessed portion 16 can be adjusted so that the position does not deviate. More excellent precision storage.

〔D-5a〕接著，更使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，在維持以位置限制用指引器923及位置修正用指引器932限制位置之狀態下，使按壓板(剝離器)940沿薄片151之厚度方向朝下側移動，藉此使按壓板940下表面抵接薄片151第1面15(參照圖42(a))。 [D-5a] Next, the press head 910 is further moved downward in the thickness direction of the sheet 151, that is, while the position is restricted by the position restricting guide 923 and the position correcting guide 932, the pressing is performed. The plate (peeler) 940 is moved downward in the thickness direction of the sheet 151, and the lower surface of the pressing plate 940 is brought into contact with the first surface 15 of the sheet 151 (see FIG. 42 (a)).

藉此，薄片151第1面15由按壓板940下表面按壓，其結果，薄片151由按壓板940限制位置。 Thereby, the first surface 15 of the sheet 151 is pressed by the lower surface of the pressing plate 940. As a result, the position of the sheet 151 is restricted by the pressing plate 940.

〔D-6a〕接著，更使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，在維持以位置限制用指引器923、位置修正用指引器932及按壓板940限制位置之狀態下，使沖壓工具921沿薄片151之厚度方向朝下側移動，直到其突起物922到達承接板952具有之穿通孔內(參照圖42(b))。 [D-6a] Next, the punch 910 is further moved downward in the thickness direction of the sheet 151, that is, the position is restricted by the position restricting guide 923, the position correcting guide 932, and the pressing plate 940. Next, the pressing tool 921 is moved downward in the thickness direction of the sheet 151 until the protrusion 922 reaches the through hole provided in the receiving plate 952 (see FIG. 42 (b)).

藉此，薄片151對應突起物922抵接之位置之部分作為沖壓物17被衝壓，其結果，如圖40(b)所示，於薄片151形成進給孔11。 As a result, the portion of the sheet 151 corresponding to the position where the protrusion 922 abuts is punched as the punch 17, and as a result, the feed hole 11 is formed in the sheet 151 as shown in FIG. 40 (b).

如此以沖壓工具921衝壓薄片151之際，因位置限制用指引器923、位置修正用指引器932及按壓板940，薄片151被限制位置，故可確實防止薄片151位置偏離。因此，可相對於第1凹部12以優異之位置精度形成進給孔11。 When the sheet 151 is punched with the punching tool 921 in this manner, the position restriction guide 923, the position correction guide 932, and the pressing plate 940 restrict the position of the sheet 151, so that the position deviation of the sheet 151 can be reliably prevented. Therefore, the feed hole 11 can be formed with excellent positional accuracy with respect to the first recessed portion 12.

〔D-7a〕接著，使沖壓頭910沿薄片151之厚度方向朝上側移動，亦即，使位置限制用指引器923、指引器銷931、位置修正用指引器932及按壓板940沿薄片151之厚度方向朝上側移動，藉此解除以此等者限制薄片151之位置(參照圖42(c))。 [D-7a] Next, the punch 910 is moved upward in the thickness direction of the sheet 151, that is, the position restricting guide 923, the guide pin 931, the position correcting guide 932, and the pressing plate 940 are moved along the sheet 151. By moving the thickness direction upward, the position of the restriction sheet 151 is released (see FIG. 42 (c)).

又，將此薄片151自薄片151前進方向入口側朝出口側搬運之，藉此供薄片151第2次進給孔11之衝壓。 The sheet 151 is conveyed from the entrance side toward the exit side of the sheet 151 in the advancing direction, whereby the sheet 151 is punched by the second feeding hole 11.

依如以上之程序，實施進給孔11之第1次沖壓。 According to the above procedure, the first punching of the feed hole 11 is performed.

<<第2次沖壓>> << Second press >>

其次，進行以沖壓模具900對薄片151之進給孔11之第2次沖壓，亦即使用沖壓工具921衝壓薄片151之第2次。第2次沖壓中，沖壓模具900具有之各部對應形成第1凹部12、第2凹部16及第1次進給孔11之薄片151各部，如以下配置。 Next, the second punching of the feed hole 11 of the sheet 151 with the punching die 900 is performed, that is, the second punching of the sheet 151 using the punching tool 921 is performed. In the second punching, each part of the punching die 900 corresponding to each part of the sheet 151 forming the first recessed part 12, the second recessed part 16, and the first feeding hole 11 is arranged as follows.

亦即，如圖39(b)所示，位置修正用指引器932在自薄片151上側觀察薄片151時，沖壓工具921具有之突起物922之薄片151前進方向入口側與出口側各外側，對應第2凹部16，將其前端部***第2凹部16內。 That is, as shown in FIG. 39 (b), when the position correcting guide 932 observes the sheet 151 from the upper side of the sheet 151, the sheet 151 of the projection 922 provided in the punching tool 921 advances in the entrance side and the exit side of the exit side, corresponding to The second recessed portion 16 has a distal end portion inserted into the second recessed portion 16.

且指引器銷931於沖壓工具921具有之突起物922之薄片151前進方向出口側，對應因第1次沖壓形成之進給孔11，其前端部插通進給孔11。 The guide pin 931 is on the exit side of the sheet 151 of the protrusion 922 provided in the punching tool 921 in the advancing direction, and corresponds to the feed hole 11 formed by the first punching, and the front end portion thereof is inserted into the feed hole 11.

以下，依序說明關於使用如此配置各部之沖壓模具900，形成進給孔11之方法。 Hereinafter, a method of forming the feed hole 11 using the punching die 900 in which the parts are arranged in this manner will be described in order.

〔D-1b〕首先，如圖40(b)所示，將形成第1凹部12、第2凹部16並因第1次沖壓形成進給孔11之薄片151自薄片151前進方向入口側朝出口側搬運之，藉此在支持台950上搬運薄片151(參照圖43(a))。 [D-1b] First, as shown in FIG. 40 (b), the sheet 151 that forms the first recessed portion 12 and the second recessed portion 16 and forms the feed hole 11 by the first punching is moved from the inlet side of the sheet 151 to the exit side The sheet 151 is conveyed on the side by this (see FIG. 43 (a)).

〔D-2b〕接著，使沖壓頭910沿薄片151之厚度方向朝下側移動，亦 即，使指引器銷931沿薄片151之厚度方向朝下側移動，藉此指引器銷931前端部插通因第1次衝壓形成之進給孔11內(參照圖43(b))。 [D-2b] Next, the punch 910 is moved downward in the thickness direction of the sheet 151, and That is, the pointer pin 931 is moved downward in the thickness direction of the sheet 151, whereby the front end portion of the pointer pin 931 is inserted into the feed hole 11 formed by the first punching (see FIG. 43 (b)).

藉此，因第1次衝壓形成之進給孔11由指引器銷931限制位置。 Thereby, the position of the feed hole 11 formed by the first punching is restricted by the pointer pin 931.

在此，本程序中，指引器銷931前端部雖插通進給孔11，但作為指引器銷931前端部之形狀，可舉出例如以下構成。 Here, although the front end portion of the pointer pin 931 is inserted into the feeding hole 11 in this procedure, the shape of the front end portion of the pointer pin 931 may be, for example, the following configuration.

亦即，首先，如圖47(A1)所示，可舉出下列者：指引器銷931之基端部側外徑為S(mm)，前端側外徑為T(mm)，進給孔11之內徑為R(mm)時，指引器銷931呈於自其基端朝前端途中縮徑，且其前端部以平坦面構成之形狀。 That is, first, as shown in FIG. 47 (A1), the following can be cited: the outer diameter of the base end portion of the guide pin 931 is S (mm), the outer diameter of the front end side is T (mm), and the feed hole When the inner diameter of 11 is R (mm), the guide pin 931 is reduced in diameter from its base end to its front end, and its front end portion is formed with a flat surface.

此時，如圖47(A1)所示，沿薄片151之厚度方向，指引器銷931前端平坦面與薄片151第1面15一致之際，指引器銷931之中心軸，與進給孔11之中心軸之位置偏離之大小，亦即，進給孔11因指引器銷931限制位置之最大量為ε(mm)時，ε可以ε=(R-T)/2表示。此時，宜形成指引器銷931前端部之形狀，俾滿足ε≧0.2。 At this time, as shown in FIG. 47 (A1), along the thickness direction of the sheet 151, when the flat surface of the front end of the pointer pin 931 coincides with the first surface 15 of the sheet 151, the center axis of the pointer pin 931 and the feed hole 11 The magnitude of the deviation of the position of the central axis, that is, when the maximum position of the feed hole 11 restricted by the pointer pin 931 is ε (mm), ε can be expressed by ε = (RT) / 2. At this time, it is preferable to form the shape of the front end portion of the pointer pin 931 so that 俾 satisfies ε ≧ 0.2.

且如圖47(A2)所示，指引器銷931插通薄片151，俾沿薄片151之厚度方向，指引器銷931前端縮徑之部分自薄片151第2面13突出之際，指引器銷931之中心軸，與進給孔11之中心軸之位置偏離之大小為W(mm)時，W可以W=(R-S)/2表示。此時，宜形成指引器銷931前端部之形狀，俾滿足0<W≦0.015。 And as shown in FIG. 47 (A2), the pointer pin 931 is inserted through the sheet 151, and along the thickness direction of the sheet 151, when the part of the front end of the pointer pin 931 has a reduced diameter protruding from the second surface 13 of the sheet 151, the pointer pin When the position of the central axis of 931 deviates from the central axis of the feed hole 11 by W (mm), W can be expressed as W = (RS) / 2. At this time, the shape of the front end portion of the guide pin 931 should be formed, and 俾 satisfies 0 <W ≦ 0.015.

如此，如圖47(A1)、(A2)所示，指引器銷931插通進給孔11，而此時，指引器銷931之中心軸與指引器銷931前端部(縮徑部)側面構成之角度為λ(°)時，宜形成指引器銷931前端部之形狀，俾滿足0<R-S≦0.03，0≦T≦S-0.4，滿足10°≦λ≦30°。 In this way, as shown in FIGS. 47 (A1) and (A2), the pointer pin 931 is inserted into the feed hole 11, and at this time, the center axis of the pointer pin 931 and the side of the front end portion (reduced diameter portion) of the pointer pin 931 When the formed angle is λ (°), the shape of the front end of the guide pin 931 should be formed. 俾 satisfies 0 <RS ≦ 0.03, 0 ≦ T ≦ S-0.4, and 10 ° ≦ λ ≦ 30 °.

藉由滿足如此之關係，如圖47(A1)、(A2)所示，於進給孔11內，對應其之指引器銷931將其插通，藉此如後述可於第2凹部16內，將對應其形狀之位置修正用指引器932前端部在位置不偏離之情形下，以更優異之精度收納之。 By satisfying such a relationship, as shown in FIGS. 47 (A1) and (A2), the guide pin 931 is inserted into the feed hole 11 so as to be inserted into the second recess 16 as described later. The front end portion of the position correction guide 932 corresponding to its shape is stored with better accuracy without being deviated.

且如圖47(B1)所示，可舉出下列者：指引器銷931之基端部側外徑為S(mm)，進給孔11之內徑為R(mm)時，指引器銷931以自其基端從朝前端途中即縮徑，其前端部為針狀之形狀構成。 And as shown in FIG. 47 (B1), the following can be cited: when the outer diameter of the base end side of the pointer pin 931 is S (mm), and the inner diameter of the feed hole 11 is R (mm), the pointer pin 931 is reduced in diameter from the base end toward the front end, and the front end portion is needle-shaped.

此時，如圖47(B1)所示，沿薄片151之厚度方向，呈針狀之指引器銷931前端與薄片151第1面15一致之際，指引器銷931之中心軸，與進給孔11之中心軸之位置偏離之大小，亦即，進給孔11因指引器銷931限制位置之最大量為ε(mm)時，ε可以ε=R/2表示。 At this time, as shown in FIG. 47 (B1), along the thickness direction of the sheet 151, when the front end of the needle-shaped pointer pin 931 coincides with the first surface 15 of the sheet 151, the center axis of the pointer pin 931 and the feed The magnitude of the deviation of the position of the central axis of the hole 11, that is, when the maximum limit position of the feed hole 11 due to the pointer pin 931 is ε (mm), ε can be expressed by ε = R / 2.

且如圖47(B2)所示，指引器銷931插通薄片151，俾沿薄片151之厚度方向，指引器銷931前端縮徑之部分自薄片151第2面13突出之際，指引器銷931之中心軸，與進給孔11之中心軸之位置偏離之大小為W(mm)時，W可以W=(R-S)/2表示。此時，宜形成指引器銷931前端部之形狀，俾滿足0<W≦0.015。 And as shown in FIG. 47 (B2), the pointer pin 931 is inserted through the sheet 151, and along the thickness direction of the sheet 151, when the part of the front end of the pointer pin 931 has a reduced diameter protruding from the second surface 13 of the sheet 151, the pointer pin When the position of the central axis of 931 deviates from the central axis of the feed hole 11 by W (mm), W can be expressed as W = (RS) / 2. At this time, the shape of the front end portion of the guide pin 931 should be formed, and 俾 satisfies 0 <W ≦ 0.015.

如此，如圖47(B1)、(B2)所示，指引器銷931插通進給孔11，而此時，宜形成指引器銷931前端部之形狀，俾滿足0<R-S≦0.03。 In this way, as shown in FIGS. 47 (B1) and (B2), the pointer pin 931 is inserted into the feed hole 11, and at this time, the shape of the front end portion of the pointer pin 931 should be formed so that 俾 satisfies 0 <R-S ≦ 0.03.

藉由滿足如此之關係，如圖47(B1)、(B2)所示，於進給孔11內，對應其之指引器銷931將其插通，藉此如後述可於第2凹部16內，將對應其形狀之位置修正用指引器932前端部在位置不偏離之情形下，以更優異之精度收納之。 By satisfying such a relationship, as shown in FIGS. 47 (B1) and (B2), the guide pin 931 is inserted into the feed hole 11 so that it can be inserted into the second recess 16 as described later. The front end portion of the position correction guide 932 corresponding to its shape is stored with better accuracy without being deviated.

〔D-3b〕接著，更使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，使位置修正用指引器932沿薄片151之厚度方向朝下側移動，藉此 將位置修正用指引器932前端部***第2凹部16內(參照圖43(c))。 [D-3b] Next, the punch 910 is moved further downward in the thickness direction of the sheet 151, that is, the position correction guide 932 is moved downward in the thickness direction of the sheet 151, thereby The tip of the position correction guide 932 is inserted into the second recessed portion 16 (see FIG. 43 (c)).

藉此，第2凹部16由位置修正用指引器932限制位置。 Thereby, the position of the second recessed portion 16 is restricted by the position correction guide 932.

R2 = W = (RS) / 2. At this time, if it is assumed that the sheet 151 is rotated around the center PC1, the rotation angle ωp of the feed hole 11 can be expressed by the following formulas (5-1) and (5-2). When the intersections of circles 935 and 936 are respectively PP41 and PP42, and the coordinates of their intersections are (Xp41, Yp41) and (Xp42, Yp42), the coordinates of these intersections can be expressed by the following formulas (6) and (7), respectively. .

When the relationship of ωr11 to 14 <ωp is used, the position correction guide 932 cannot be used to limit the second recessed portion 16. Its location.

又，依如上述之順序實施，以指引器銷931及位置修正用指引器932限制位置時，第2凹部16由位置修正用指引器932限制位置之最大量為U(mm)，指引器銷931插通薄片151，俾沿薄片151之厚度方向，指引器銷931前端縮徑之部分自薄片151第2面13突出之際指引器銷931之中心軸，與進給孔11之中心軸之位置偏離之大小為W(mm)時，宜滿足W≦U，滿足0.015≦U-W≦0.5。藉由滿足該關係，實施以指引器銷931限制位置後，以位置修正用指引器932限制位置之構成，藉此於後程序〔D-5b〕，可使進給孔11以更優異之位置精度形成於薄片151。 When the position is restricted by the guide pin 931 and the position correction guide 932, the maximum amount of the position of the second recessed portion 16 restricted by the position correction guide 932 is U (mm). 931 is inserted into the sheet 151, and along the thickness direction of the sheet 151, the central axis of the pointer pin 931 and the central axis of the feed hole 11 when the part of the front end of the pointer pin 931 shrinks from the second surface 13 of the sheet 151 When the position deviation is W (mm), it should satisfy W ≦ U and 0.015 ≦ UW ≦ 0.5. By satisfying this relationship, after the position is restricted by the director pin 931 and the position is restricted by the position correction director 932, the following procedure [D-5b] can be used to make the feed hole 11 a better position Precision is formed in the sheet 151.

〔D-4b〕接著，更使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，在維持以指引器銷931及位置修正用指引器932限制位置之狀態下，使按壓板(剝離器)940沿薄片151之厚度方向朝下側移動，藉此使按壓板940下表面抵接薄片151第1面15(參照圖43(d))。 [D-4b] Next, the pressing head 910 is moved further downward in the thickness direction of the sheet 151, that is, while the position is restricted by the guide pin 931 and the position correction guide 932, the pressing plate ( The peeler) 940 moves downward in the thickness direction of the sheet 151, thereby bringing the lower surface of the pressing plate 940 into contact with the first surface 15 of the sheet 151 (see FIG. 43 (d)).

藉此，薄片151第1面15由按壓板940下表面按壓，其結果，薄片151由按壓板940限制位置。 Thereby, the first surface 15 of the sheet 151 is pressed by the lower surface of the pressing plate 940. As a result, the position of the sheet 151 is restricted by the pressing plate 940.

〔D-5b〕接著，更使沖壓頭910沿薄片151之厚度方向朝下側移動，亦即，在維持以指引器銷931、位置修正用指引器932及按壓板940限制位置之狀態下，使沖壓工具921沿薄片151之厚度方向朝下側移動，直到其突起物922到達承接板952具有之穿通孔內(參照圖44(a))。 [D-5b] Next, the punch 910 is further moved downward in the thickness direction of the sheet 151, that is, while maintaining the position restricted by the guide pin 931, the position correction guide 932, and the pressing plate 940, The pressing tool 921 is moved downward in the thickness direction of the sheet 151 until the protrusion 922 reaches the through hole provided in the receiving plate 952 (see FIG. 44 (a)).

藉此，薄片151對應突起物922抵接之位置之部分作為沖壓物17被衝壓，其結果，如圖40(c)所示，於薄片151形成進給孔11。 As a result, the portion of the sheet 151 corresponding to the position where the protrusion 922 abuts is punched as a punch 17. As a result, as shown in FIG. 40 (c), the feed hole 11 is formed in the sheet 151.

如此以沖壓工具921衝壓薄片151之際，以指引器銷931、位置修正用指引器932及按壓板940限制薄片151之位置，故可確實防止薄片151位置偏離。因此，可相對於第1凹部12以優異之位置精度形成進給孔11。 When the sheet 151 is punched with the punching tool 921 in this manner, the position of the sheet 151 is restricted by the guide pin 931, the position correction guide 932, and the pressing plate 940, so that the position of the sheet 151 can be reliably prevented from deviating. Therefore, the feed hole 11 can be formed with excellent positional accuracy with respect to the first recessed portion 12.

〔D-6b〕接著，更使沖壓頭910沿薄片151之厚度方向朝上側移動，亦即，使指引器銷931、位置修正用指引器932及按壓板940沿薄片151之厚度方向朝上側移動，藉此解除以此等者限制薄片151之位置(參照圖44(b))。 [D-6b] Next, the punch 910 is further moved upward in the thickness direction of the sheet 151, that is, the guide pin 931, the position correction guide 932, and the pressing plate 940 are moved upward in the thickness direction of the sheet 151. Thus, the position of the sheet 151 is released by these persons (refer to FIG. 44 (b)).

又，將此薄片151自薄片151前進方向入口側朝出口側搬運之，藉此供對薄片151衝壓第3次進給孔11。 In addition, the sheet 151 is conveyed from the inlet side toward the exit side of the sheet 151 in the advancing direction, thereby punching the sheet 151 for the third feeding hole 11.

依如以上之程序，實施進給孔11之第2次沖壓。又，藉由重複實施此第2次沖壓，亦即，依序實施第2次以後之沖壓，形成複數進給孔11，其結果，可製造於薄片151具有第1凹部12、第2凹部16及進給孔11之製作用薄片155。 According to the above procedure, the second punching of the feed hole 11 is performed. Furthermore, the second punching is repeatedly performed, that is, the second and subsequent punches are sequentially performed to form a plurality of feed holes 11. As a result, the sheet 151 can be manufactured with the first recessed portion 12 and the second recessed portion 16. And a sheet 155 for manufacturing the feed hole 11.

〔E〕其次，將獲得之製作用薄片155以第1面15或第2面13為捲筒(芯材)側捲繞之(捲繞程序)。 [E] Next, the obtained production sheet 155 is wound with the first surface 15 or the second surface 13 as the roll (core material) side (winding procedure).

藉由如此將製作用薄片155於捲筒捲繞之，可對製作用薄片155保管時及輸送時之省空間化有所貢獻。 By winding the production sheet 155 on a roll in this way, it is possible to contribute to space saving during storage and transportation of the production sheet 155.

如以上，在捲繞於捲筒之狀態下製造製作用薄片155。 As described above, the production sheet 155 is manufactured in a state of being wound on a roll.

又，亦可在本程序〔E〕前，先使所獲得之製作用薄片155包含1對排成1列之複數第1凹部12與排成1列之複數進給孔11，且排除排成1列之複數第2凹部16，沿製作用薄片155之長邊方向，以既定寬使製作用薄片155開縫(切斷)。藉此，可獲得2個運送帶1，於本程序〔E〕，可製造2個捲繞於捲筒之狀態之運送帶1。如此使製作用薄片155以既定寬開縫而獲得運送帶1時，藉由使製作用薄片155以既定寬開縫者構成切斷部，本發 明之運送帶製造裝置以除薄片供給部700、成形部800與沖壓部外，更包含該切斷部者構成。 In addition, before the procedure [E], the obtained manufacturing sheet 155 may include a pair of plural first recesses 12 arranged in one row and plural feeding holes 11 arranged in one row, and the arrangement may be excluded. The plurality of second recessed portions 16 in one row are slit (cut) in a predetermined width along the longitudinal direction of the production sheet 155 with a predetermined width. Thereby, two conveyer belts 1 can be obtained, and in this procedure [E], two conveyer belts 1 wound on a roll can be manufactured. When the production sheet 1 is obtained by slitting the production sheet 155 in a predetermined width in this manner, the cutting portion is formed by forming the production sheet 155 with a predetermined width.
