Description

拉鏈鏈條的矯正裝置及矯正方法Correction device and method for zipper chain

本發明有關於一種當實施使用超臨界流體的染色處理時，對因熱收縮而產生有捲曲傾向（curling tendency）的染色後的拉鏈用拉鏈鏈條的形態進行矯正的矯正裝置及矯正方法。The present invention relates to a correction device and a correction method for correcting the shape of a dyed slide fastener chain that has a curling tendency due to heat shrinkage when a dyeing process using a supercritical fluid is performed.

先前，於進行纖維製品的染色的情況下，使用大量的水作為染色介質，但被指出水資源的節約或廢液處理的問題等，要求開發對於環境的負載更低的染色技術。其中，作為廢液的排出量極少且對於環境的負載小的染色方法，提出有使用超臨界流體作為染色介質的方法。In the past, when dyeing fiber products, a large amount of water was used as a dyeing medium. However, problems such as water conservation and waste liquid treatment have been pointed out, and development of a dyeing technology with a lower load on the environment has been required. Among them, a method using a supercritical fluid as a dyeing medium is proposed as a dyeing method in which the discharge amount of waste liquid is extremely small and the load on the environment is small.

超臨界流體為在溫度及壓力為物質的臨界溫度及臨界壓力以上時所形成的凝縮性高密度流體，且兼具氣體的擴散性與液體的溶解性。另外，作為成為超臨界流體的化合物，已知有水或二氧化碳等。使用超臨界二氧化碳作為超臨界流體的染色方法為於超臨界二氧化碳中溶解染料而對纖維製品等進行染色的方法。A supercritical fluid is a condensable high-density fluid formed when the temperature and pressure are above the critical temperature of the substance and the critical pressure, and has both the diffusivity of a gas and the solubility of a liquid. Moreover, as a compound which becomes a supercritical fluid, water, carbon dioxide, etc. are known. A dyeing method using supercritical carbon dioxide as a supercritical fluid is a method of dissolving a dye in supercritical carbon dioxide and dyeing a fiber product or the like.

例如與使纖維製品浸漬於染色液中的現有的染色方法相比，使用該超臨界二氧化碳的染色方法具有可縮短染色時間、可循環使用二氧化碳、不排出染色廢液、不需染色後的纖維製品的乾燥步驟、可回收過剩的染料等大量的優點。For example, compared with the conventional dyeing method in which a fiber product is immersed in a dyeing solution, the dyeing method using the supercritical carbon dioxide has a shortened dyeing time, can recycle carbon dioxide, does not discharge dyeing waste liquid, and does not require fiber products after dyeing. There are a lot of advantages such as a drying step, and excess dye can be recovered.

關於此種使用超臨界二氧化碳的染色方法，例如日本專利特開2005-273098號公報（專利文獻1）中揭示有使用超臨界二氧化碳而於纖維製品等被染色物上再現性良好地形成具有濃淡的漸變（gradation）圖案的方法及裝置。Regarding such a dyeing method using supercritical carbon dioxide, for example, Japanese Patent Application Laid-Open No. 2005-273098 (Patent Document 1) discloses that supercritical carbon dioxide is used to form reproducible dyed materials with good reproducibility on dyed objects such as fiber products. Method and device for gradation pattern.

專利文獻2的高壓釜111以如下方式形成：可於將纖維製品捲繞於未圖示的滾筒（drum）（或繞線管（bobbin））的狀態下將纖維製品連同該滾筒收容於內部並加以保持。另外，高壓釜111具有使超臨界二氧化碳流入內部的流入口、與使超臨界二氧化碳自內部流出的流出口。於該情況下，自流入口流入高壓釜111內的超臨界二氧化碳自保持於高壓釜111內的滾筒的中心軸部朝向外側沿徑方向流動，而自高壓釜111的流出口流出至循環路徑112。The autoclave 111 of Patent Document 2 is formed in such a manner that the fiber product can be accommodated inside the drum (or bobbin) in a state where the fiber product is wound around a drum (or bobbin) (not shown) and Keep it up. The autoclave 111 has an inflow port through which supercritical carbon dioxide flows into the interior, and an outflow port through which supercritical carbon dioxide flows out from the inside. In this case, the supercritical carbon dioxide flowing into the autoclave 111 from the inflow port flows radially outward from the central axis portion of the drum held in the autoclave 111, and flows out from the outflow port of the autoclave 111 to the circulation path 112.

循環路徑112連接於高壓釜111的流出口與流入口，並且於循環路徑112上設置有循環泵113與加熱×冷卻部114。藉由該循環路徑112，可使自高壓釜111的流出口流出的超臨界二氧化碳再次返回至高壓釜111的流入口而加以循環。The circulation path 112 is connected to the outflow port and the inflow port of the autoclave 111, and a circulation pump 113 and a heating × cooling section 114 are provided on the circulation path 112.

The temperature in the autoclave 111 is controlled by the temperature control unit 115. The pressure control unit 116 includes a pressure sensor 116a that measures the pressure in the autoclave 111, and a pressure control main unit that controls the operation of the supply pump 122 and the opening and closing of the discharge valve 131 based on the measurement result of the pressure sensor 116a. 116b. The pressure in the autoclave 111 is controlled by the pressure control unit 116.

供給單元120包括：儲存罐（storage tank）121，貯存二氧化碳；供給泵122，自儲存罐121朝向染色×清洗單元110供給二氧化碳；冷卻器（cooler）部（第1冷卻器部）123，配置於儲存罐121與供給泵122間；及預熱部124，配置於供給泵122的下游側，於供給至染色×清洗單元110前對二氧化碳進行預加熱。The supply unit 120 includes a storage tank 121 that stores carbon dioxide, a supply pump 122 that supplies carbon dioxide from the storage tank 121 toward the dyeing × washing unit 110, and a cooler unit (first cooler unit) 123, which is disposed at Between the storage tank 121 and the supply pump 122; and the preheating unit 124 is disposed on the downstream side of the supply pump 122, and pre-heats carbon dioxide before being supplied to the dyeing × washing unit 110.

供給單元120的供給泵122自儲存罐121吸引液狀的二氧化碳而送給至染色×清洗單元110。另外，該供給泵122通過染色×清洗單元110的壓力控制部116而控制二氧化碳的流量（供給量）。The supply pump 122 of the supply unit 120 sucks liquid carbon dioxide from the storage tank 121 and sends it to the dyeing × washing unit 110. The supply pump 122 controls the flow rate (supply amount) of carbon dioxide by the pressure control unit 116 of the dyeing / washing unit 110.

另外，藉由將供給泵122設置於配置在與循環路徑112不同的路徑的管路，於在高壓釜111內製品的染色處理結束後，一面利用循環泵113使超臨界二氧化碳於高壓釜111及循環路徑112中循環，一面將不含染料的純的超臨界二氧化碳連續地供給至洗淨單元。因此，可緊接著染色處理而連續地進行製品及高壓釜111的清洗處理。In addition, the supply pump 122 is provided in a pipeline disposed on a path different from the circulation path 112. After the dyeing process of the products in the autoclave 111 is completed, the supercritical carbon dioxide is applied to the autoclave 111 and the circulation pump 113 while While circulating in the circulation path 112, pure supercritical carbon dioxide containing no dye is continuously supplied to the washing unit. Therefore, the washing process of the product and the autoclave 111 can be continuously performed immediately after the dyeing process.

供給單元120的冷卻器部123配置於供給泵122的上游，對藉由供給泵122而自儲存罐121吸引來的二氧化碳進行冷卻。藉由利用該冷卻器部123對二氧化碳進行冷卻，可將二氧化碳以液體狀態送至供給泵122，藉此，可使供給泵122中的二氧化碳的供給穩定。The cooler section 123 of the supply unit 120 is disposed upstream of the supply pump 122 and cools the carbon dioxide that is sucked from the storage tank 121 by the supply pump 122. By cooling the carbon dioxide with the cooler unit 123, the carbon dioxide can be sent to the supply pump 122 in a liquid state, whereby the supply of the carbon dioxide in the supply pump 122 can be stabilized.

預熱部124可於供給至染色×清洗單元110前對通過供給泵122的二氧化碳進行預加熱而形成為超臨界狀態。另外，於供給泵122與染色×清洗單元110之間設置有可將自供給泵122送給的二氧化碳不經由預熱部124而供給至染色×清洗單元110的旁通路徑125。進而，於預熱部124的上游位置與旁通路徑125配置有用以切換二氧化碳的流路的第1開閉閥126及第2開閉閥127。The pre-heating unit 124 may pre-heat the carbon dioxide passing through the supply pump 122 before being supplied to the dyeing × washing unit 110 to form a supercritical state. A bypass path 125 is provided between the supply pump 122 and the dyeing / washing unit 110 to supply carbon dioxide sent from the supply pump 122 to the dyeing / washing unit 110 without passing through the preheating unit 124. Furthermore, a first on-off valve 126 and a second on-off valve 127 for switching the flow path of carbon dioxide are arranged at the upstream position of the preheating unit 124 and the bypass path 125.

排出單元130具有自循環路徑112排出超臨界二氧化碳的排出閥131、與配置於排出閥131的下游側的分離槽132。於該情況下，排出閥131與壓力控制部116連接，且排出閥131的開閉由壓力控制部116控制。分離槽132將染料及其他雜質自所排出而氣化的二氧化碳分離。The discharge unit 130 includes a discharge valve 131 that discharges supercritical carbon dioxide from the circulation path 112 and a separation tank 132 that is disposed on the downstream side of the discharge valve 131. In this case, the discharge valve 131 is connected to the pressure control unit 116, and the opening and closing of the discharge valve 131 is controlled by the pressure control unit 116. The separation tank 132 separates carbon dioxide that is vaporized from the discharged dye and other impurities.

回收單元140具有自分離槽132吸引氣體狀態的二氧化碳並加以壓縮的壓縮機141、與將經壓縮的二氧化碳冷卻而形成為液體狀態的後冷卻器（after cooler）部142。利用後冷卻器部142液化的二氧化碳被搬送至供給單元120的儲存罐121並加以貯存。The recovery unit 140 includes a compressor 141 that sucks and compresses carbon dioxide in a gaseous state from the separation tank 132, and an after cooler unit 142 that cools the compressed carbon dioxide into a liquid state. The carbon dioxide liquefied by the aftercooler unit 142 is transferred to the storage tank 121 of the supply unit 120 and stored.

於使用如上所述的專利文獻2的染色×清洗裝置100對纖維製品進行染色處理的情況下，首先，將纖維製品捲繞於滾筒，並將纖維製品連同滾筒收容於高壓釜111的內部並加以保持。另外，將染料（分散染料）與纖維製品一起收容於該高壓釜111內。In the case where the fiber product is dyed using the dyeing × washing device 100 of Patent Document 2 described above, first, the fiber product is wound around a drum, and the fiber product and the drum are housed inside the autoclave 111 and are applied. maintain. A dye (disperse dye) is contained in the autoclave 111 together with the fiber product.

繼而，驅動供給單元120的供給泵122，將二氧化碳自儲存罐121經由供給泵122及預熱部124而供給至染色×清洗單元110。此時，二氧化碳經供給泵122升壓，進而經預熱部124加熱，以超臨界狀態供給至染色×清洗單元110。Next, the supply pump 122 of the supply unit 120 is driven to supply carbon dioxide from the storage tank 121 to the dyeing / washing unit 110 via the supply pump 122 and the preheating unit 124. At this time, the carbon dioxide is boosted by the supply pump 122, and further heated by the preheating unit 124, and is supplied to the dyeing / washing unit 110 in a supercritical state.

染色×清洗單元110中，於自供給單元120供給超臨界狀態的二氧化碳（以下，稱為超臨界二氧化碳）時，驅動循環泵113而使所供給的超臨界二氧化碳於循環經路112及高壓釜111中循環。於該情況下，導入高壓釜111內的超臨界二氧化碳自捲繞纖維製品的滾筒的中心軸部向外周部沿徑方向流動，而自高壓釜111的流出口流出。In the dyeing / washing unit 110, when supercritical carbon dioxide (hereinafter referred to as supercritical carbon dioxide) is supplied from the supply unit 120, the circulation pump 113 is driven to supply the supplied supercritical carbon dioxide in the circulation path 112 and the autoclave 111. In the loop. In this case, the supercritical carbon dioxide introduced into the autoclave 111 flows in the radial direction from the central axis portion of the drum wound with the fiber product toward the outer peripheral portion, and flows out from the outflow port of the autoclave 111.

另外，溫度控制部115藉由一面對高壓釜111內的溫度進行測定，一面對配置於循環經路112上的加熱×冷卻部114的運轉進行控制，而將高壓釜111內的溫度保持為預先設定的規定的設定溫度。進而，壓力控制部116藉由一面對高壓釜111內的壓力進行測定，一面對供給泵122的運轉與排出閥131的開閉進行控制，而將高壓釜111內的壓力保持為預先設定的規定的設定壓力。In addition, the temperature control unit 115 measures the temperature in the autoclave 111 and controls the operation of the heating × cooling unit 114 disposed on the circulation path 112 to maintain the temperature in the autoclave 111. It is a predetermined temperature set in advance. Further, the pressure control unit 116 measures the pressure in the autoclave 111 and controls the operation of the supply pump 122 and the opening and closing of the discharge valve 131 to maintain the pressure in the autoclave 111 in advance. Specified set pressure.

藉由將如上所述的超臨界二氧化碳於高壓釜111中的循環進行規定的時間，收容於高壓釜111內的纖維製品的纖維因超臨界二氧化碳的熱而膨潤，並且溶解有染料的超臨界二氧化碳進入至該膨潤的纖維中並擴散，因此將纖維製品染色。此種使用超臨界二氧化碳的染色處理中，可於不使用水的條件下以相對較短的時間對纖維製品進行染色。By circulating the supercritical carbon dioxide in the autoclave 111 as described above for a predetermined period of time, the fibers of the fiber product contained in the autoclave 111 swell due to the heat of the supercritical carbon dioxide, and the supercritical carbon dioxide in which the dye is dissolved is dissolved. It enters into this swollen fiber and spreads, so the fiber product is dyed. In such a dyeing process using supercritical carbon dioxide, a fiber product can be dyed in a relatively short time without using water.

進而，專利文獻2的染色×清洗裝置100中，所述染色處理結束後，對纖維製品與高壓釜111等的超臨界二氧化碳所通過的部位連續地進行清洗處理。該清洗處理中，一面進行利用循環經路112的超臨界二氧化碳的循環，一面驅動供給泵122，並且打開排出閥131。藉此，不含染料的純的超臨界二氧化碳自供給單元120供給至染色×清洗單元110，同時溶解有染料的超臨界二氧化碳自染色×清洗單元110經由排出閥131而被排出。Furthermore, in the dyeing × washing device 100 of Patent Document 2, after the dyeing process is completed, the fiber products and the parts through which supercritical carbon dioxide such as the autoclave 111 passes are continuously cleaned. In this cleaning process, the supply pump 122 is driven while the supercritical carbon dioxide cycle using the circulation path 112 is being circulated, and the discharge valve 131 is opened. Thereby, pure supercritical carbon dioxide containing no dye is supplied from the supply unit 120 to the dyeing × washing unit 110, and the supercritical carbon dioxide with the dye dissolved therein is discharged through the discharge valve 131.

其結果，可一面使於高壓釜111及循環路徑112中循環的超臨界二氧化碳中的染料的濃度隨時間經過而逐漸減少，一面利用該超臨界二氧化碳進行纖維製品或高壓釜111等的清洗。另外，此時，一面進行纖維製品等的清洗，一面利用溫度控制部115對加熱×冷卻部114進行控制，而使高壓釜111內的溫度以規定的降溫速度降低至玻璃轉移溫度以下。藉此，可抑制溶解於超臨界二氧化碳的染料析出，並且使染色時所膨潤的纖維製品的纖維收縮，抑制染料自纖維脫出而顏色脫落。As a result, while the concentration of the dye in the supercritical carbon dioxide circulating in the autoclave 111 and the circulation path 112 gradually decreases with the passage of time, the supercritical carbon dioxide can be used to clean the fiber products, the autoclave 111, and the like. In addition, at this time, while the fiber products and the like are being cleaned, the temperature control unit 115 is used to control the heating × cooling unit 114 so that the temperature in the autoclave 111 is reduced to a glass transition temperature or lower at a predetermined cooling rate. This can suppress the precipitation of dyes dissolved in supercritical carbon dioxide, shrink the fibers of the swollen fiber product during dyeing, and prevent the dye from coming out of the fibers and the color from falling off.

另一方面，經由排出閥131所排出並氣化的二氧化碳被搬送至分離槽132，利用該分離槽132將染料自二氧化碳分離。其後，分離了染料的二氧化碳經壓縮器壓縮後，經後冷卻器部142冷卻而液化。而且，液體狀態的二氧化碳自後冷卻器部142返回至儲存罐121而加以再利用。On the other hand, the carbon dioxide discharged and vaporized through the discharge valve 131 is transferred to a separation tank 132, and the dye is separated from the carbon dioxide by the separation tank 132. Thereafter, the carbon dioxide from which the dye has been separated is compressed by a compressor, and then cooled by the aftercooler portion 142 to be liquefied. Then, the carbon dioxide in a liquid state is returned from the aftercooler unit 142 to the storage tank 121 and reused.

根據如上所述的專利文獻2的染色×清洗裝置100，可緊接著染色處理而連續地進行纖維製品及高壓釜111的清洗處理，藉此，可高效地清洗纖維製品及高壓釜111。 [現有技術文獻] [專利文獻]According to the dyeing / washing device 100 of Patent Document 2 described above, the fiber product and the autoclave 111 can be continuously washed immediately after the dyeing process, thereby efficiently cleaning the fiber product and the autoclave 111.

[專利文獻1]日本專利特開2005-273098號公報 [專利文獻2]國際公開第2012/105011號[Patent Document 1] Japanese Patent Laid-Open No. 2005-273098 [Patent Document 2] International Publication No. 2012/105011

[發明所欲解決之課題] 關於使用超臨界流體的染色方法，如上所述，由於染色處理高效或對於環境的負荷低等，故亦對將其用於拉鏈用的拉鏈鏈條的染色的情況進行了研究。[Problems to be Solved by the Invention] As described above, the dyeing method using a supercritical fluid is also used for dyeing a zipper chain for a zipper because the dyeing process is efficient or the load on the environment is low. Research.

此處，拉鏈鏈條具有左右一對的拉鏈帶、與形成於各拉鏈帶的相對向的帶側緣部的左右鏈牙列，通常的拉鏈鏈條中，左右鏈牙列處於彼此咬合的狀態。另外，拉鏈鏈條的鏈牙列是藉由如下方式而形成：將合成樹脂製的單絲纖維呈線圈狀成形而形成連續狀的多個拉鏈鏈牙，進而將所成形的多個拉鏈鏈牙載置於拉鏈帶的帶側緣部中的一個帶面並加以縫接。Here, the zipper chain has a pair of left and right fastener tapes, and left and right element rows formed on opposite side edges of each of the fastener tapes. In a normal zipper chain, the left and right element rows are engaged with each other. In addition, the fastener element rows of the zipper chain are formed by forming a monofilament fiber made of synthetic resin in a coil shape to form a plurality of continuous fastener elements, and further carrying the formed plurality of fastener elements. One of the belt side edges of the fastener tape is placed and sewed.

因此，具有包含線圈狀的多個拉鏈鏈牙的鏈牙列的拉鏈鏈條具備如下形態：處於咬合狀態的左右鏈牙列於左右拉鏈帶的相對向的帶側緣部（拉鏈鏈條中的帶寬度方向的中央部分）中自拉鏈帶的帶表面或帶背面膨出。Therefore, a zipper chain having an element row including a plurality of coil-shaped zipper elements has a form in which the left and right elements in an engaged state are arranged at the opposite side edges of the left and right zipper belts (the width of the belt in the zipper chain) Center part of the direction) bulges from the tape surface or the tape back surface of the zipper tape.

相對於此種拉鏈用的拉鏈鏈條，例如於使用所述專利文獻2中所記載的圖4的染色×清洗裝置100而利用超臨界流體的染色方法進行染色處理的情況下，需要將筆直且長條的拉鏈鏈條於滾筒上捲繞多重，將該拉鏈鏈條連同滾筒收容於高壓釜111的內部。With respect to such a zipper chain, for example, when performing a dyeing process using a supercritical fluid dyeing method using the dyeing × washing device 100 of FIG. 4 described in the aforementioned Patent Document 2, it is necessary to make the straight and long The zipper chain of the strip is wound on the drum multiple times, and the zipper chain and the drum are housed inside the autoclave 111.

此處，如上所述，拉鏈鏈條具有處於咬合狀態的左右鏈牙列自拉鏈帶的一個帶面膨出的形態，因此於為了進行超臨界流體的染色處理而將拉鏈鏈條於滾筒上重疊捲繞多重的情況下，該拉鏈鏈條例如與如下情況同樣地一面在滾筒的軸方向上錯開一面呈螺旋狀捲繞，所述情況為將拉鏈鏈條在捲繞於滾筒的狀態下浸漬於染色液進行染色的現有的染色處理的情況。如此般將拉鏈鏈條呈螺旋狀捲繞於滾筒的捲繞方式亦有時稱為橫向捲繞（traverse winding）。Here, as described above, the zipper chain has a form in which the left and right element rows in the occluded state bulge from one side of the zipper tape. Therefore, the zipper chain is superimposed and wound on a drum in order to perform a supercritical fluid dyeing treatment. In the case of multiple, the zipper chain is spirally wound while being staggered in the axial direction of the drum in the same manner as in the case where the zipper chain is dipped in a dyeing liquid to be dyed while being wound on the drum. Of the existing dyeing process. A winding method in which a zipper chain is spirally wound around a drum in this manner is sometimes referred to as a traverse winding.

藉由如此般將拉鏈鏈條呈螺旋狀捲繞於滾筒，拉鏈鏈條的鏈牙列於其內側難以與已捲繞於滾筒的鏈牙列重合，而可將拉鏈鏈條高效地捲繞於滾筒，另外，可使捲繞於滾筒的拉鏈鏈條難以產生位置偏移。By spirally winding the zipper chain around the drum in this manner, the elements of the zipper chain are hardly overlapped with the element rows already wound on the drum, and the zipper chain can be efficiently wound on the drum. It can make it difficult for the zipper chain wound around the drum to shift position.

但是，在將拉鏈鏈條呈螺旋狀捲繞於滾筒的狀態下，實際嘗試利用使用超臨界流體的染色方法的染色處理時，判明：因拉鏈鏈條的染色處理中的超臨界流體的高溫度的加熱與染色處理後的冷卻，而會於包含合成纖維的拉鏈帶與合成樹脂製的鏈牙列上進行模仿捲繞於滾筒的形態的熱定型（heat setting），從而拉鏈鏈條整體變形。However, when the zipper chain was spirally wound around the drum, when a dyeing process using a dyeing method using a supercritical fluid was actually attempted, it was found that the high temperature heating of the supercritical fluid during the dyeing process of the zipper chain With the cooling after the dyeing process, the zipper tape containing synthetic fibers and the element rows made of synthetic resin are heat-set to imitate the shape of being wound around a roller, so that the entire zipper chain is deformed.

即，試著將染色後的經冷卻的拉鏈鏈條自滾筒抽出並觀察時，該拉鏈鏈條例如如圖3所示，對應於橫向捲繞相對於滾筒的捲繞方向而產生有偏置形狀的捲曲傾向，所述偏置形狀的捲曲傾向於拉鏈鏈條的平面視時，呈現出左右一對的鏈牙列中的一者朝向對方的鏈牙呈凸狀翹曲，並且另一者朝向對方的鏈牙呈凹狀翹曲的彎曲狀的形態。That is, when the dyed and cooled zipper chain is tried to be pulled out from the drum and observed, the zipper chain, for example, as shown in FIG. 3, has an offset-shaped curl corresponding to the lateral winding and the winding direction of the drum. When the curl of the offset shape is inclined to the planar view of the zipper chain, one of the left and right fastener element rows is convexly warped toward the opposite element, and the other is facing the opposite chain. The teeth have a curved shape with concave warping.

拉鏈鏈條因此種捲曲傾向而具備彎曲狀的形態，鏈牙列中的各拉鏈鏈牙間的間隔（換言之，拉鏈鏈牙的安裝間距）於左側的鏈牙列與右側的鏈牙列之間稍微不同，其結果，當形成拉鏈時，存在使拉頭（slider）的滑動性或操作性降低的問題。另外，如上所述般的殘留捲曲傾向的拉鏈亦產生難以筆直且完美地安裝於衣服等拉鏈附著製品的問題。The zipper chain has a curved shape due to this curling tendency. The interval between the zipper elements in the element row (in other words, the installation distance of the zipper element) is slightly between the left element row and the right element row. The difference is that, as a result, when a slide fastener is formed, there is a problem that the sliding property or operability of a slider is reduced. In addition, the zipper with a tendency to remain curled as described above also has a problem that it is difficult to mount the zipper to a zipper-attached product such as clothes straight and perfectly.

因此，判明：於在將拉鏈鏈條呈螺旋狀捲繞於滾筒的狀態下，進行利用使用超臨界流體的染色方法的染色處理的情況下，需要將因捲曲傾向所造成的染色後的彎曲的拉鏈鏈條的形態恢復為染色處理前的筆直的狀態。Therefore, it was found that when a dyeing process using a dyeing method using a supercritical fluid is performed while the zipper chain is spirally wound around a drum, it is necessary to bend the zipper after dyeing due to curling tendency. The shape of the chain returned to the straight state before the dyeing process.

本發明是鑒於所述現有的課題而成，其具體目的在於提供一種當在將拉鏈鏈條呈螺旋狀捲繞於滾筒的狀態下對該拉鏈鏈條實施使用超臨界流體的染色處理時，可容易矯正因熱收縮而產生有捲曲傾向的染色後的拉鏈鏈條的形態的拉鏈鏈條的矯正裝置及矯正方法。 [解決課題之手段]The present invention has been made in view of the conventional problems, and a specific object thereof is to provide a zipper chain that can be easily corrected when a zipper chain is dyed with a supercritical fluid while the zipper chain is spirally wound around a drum.

繼而，由本發明提供的拉鏈用拉鏈鏈條的矯正方法為如下拉鏈鏈條的矯正方法，當在捲繞於滾筒的狀態下實施使用超臨界流體的染色處理時，為了去除因熱而產生有捲曲傾向的染色後的拉鏈用拉鏈鏈條的所述捲曲傾向，而對所述拉鏈鏈條的形態進行矯正，且所述拉鏈鏈條的矯正方法的最主要特徵在於包括：供給產生有所述捲曲傾向的所述拉鏈鏈條並以規定的搬送速度進行搬送；一面搬送所供給的所述拉鏈鏈條，一面利用鏈條加熱部進行加熱；一面搬送經加熱的所述拉鏈鏈條，一面利用鏈條冷卻部進行冷卻；及對流經所述鏈條加熱部及所述鏈條冷卻部的所述拉鏈鏈條施加張力。Next, the method for correcting a zipper chain for a zipper provided by the present invention is a method for correcting a zipper chain.

After dyeing the curl tendency of the zipper chain, the shape of the zipper chain is corrected, and the most important feature of the method for correcting the zipper chain includes: supplying the zipper with the curl tendency The chain is conveyed at a predetermined conveying speed; the supplied zipper chain is heated while being heated by a chain heating section; the heated zipper chain is conveyed while being cooled by a chain cooling section; Tension is applied to the zipper chain of the chain heating portion and the chain cooling portion.

另外，本發明的矯正方法較佳為包括：一面使所述拉鏈鏈條呈鋸齒狀曲折前進，一面進行搬送；及將於所述鏈條加熱部中所搬送的所述拉鏈鏈條的搬送距離設定為短於在所述鏈條冷卻部中所搬送的所述拉鏈鏈條的搬送距離。In addition, the correction method of the present invention preferably includes: carrying the zigzag chain in a zigzag manner while conveying it; and setting a short distance of the zipper chain to be transported in the chain heating section.

Above and below 120 ° C. In addition, the correction method of the present invention is preferably included in the chain cooling section, while the zipper chain is transported, and cooled at least below a glass transition temperature by natural air cooling. [Effect of the invention]

本發明的拉鏈鏈條的矯正裝置包括：鏈條供給部，供給產生有捲曲傾向的拉鏈鏈條；鏈條搬送部，配置於鏈條供給部的下游側；鏈條加熱部，配置於鏈條供給部與鏈條搬送部間，對拉鏈鏈條進行加熱；鏈條冷卻部，配置於鏈條加熱部及鏈條搬送部間，對經加熱的拉鏈鏈條進行冷卻；及鏈條張力施加部，對流經鏈條加熱部及鏈條冷卻部的拉鏈鏈條施加張力。The straightening device for a zipper chain of the present invention includes a chain supply section for supplying a zipper chain having a tendency to curl; a chain transfer section disposed on a downstream side of the chain supply section; and a chain heating section disposed between the chain supply section and the chain transfer section. Heating the zipper chain; the chain cooling section is arranged between the chain heating section and the chain conveying section to cool the heated zipper chain; and the chain tension applying section applies the zipper chain flowing through the chain heating section and the chain cooling section tension.

此種本發明的矯正裝置中，藉由鏈條搬送部將彎曲狀的產生有捲曲傾向的拉鏈鏈條自鏈條供給部沿搬送路徑以規定的搬送速度進行搬送，並且一面利用鏈條加熱部對拉鏈鏈條進行加熱，一面利用鏈條張力施加部對流經該鏈條加熱部的拉鏈鏈條施加張力。藉此，可於鏈條加熱部的搬送路徑上，一面對拉鏈鏈條進行加熱一面延伸，而將拉鏈鏈條的形態形成為筆直，並且可於左右鏈牙列間使拉鏈鏈牙間的間隔（以下，略記為鏈牙間隔）一致。In such a correction device of the present invention, a zipper chain having a curved tendency to curl is transported from the chain supply section at a predetermined transport speed along the transport path by the chain transport section, and the zipper chain is transported by the chain heating section While heating, the chain tension applying portion applies tension to the zipper chain passing through the chain heating portion. With this, the zipper chain can be heated and extended while facing the zipper chain on the conveying path of the chain heating section, and the zipper chain can be spaced between the left and right element rows (the following) , Slightly referred to as the element interval).

另外，本發明的矯正裝置中，利用鏈條加熱部對拉鏈鏈條進行加熱後，一面利用鏈條冷卻部對該經加熱的拉鏈鏈條進行冷卻，一面利用鏈條張力施加部對流經該鏈條冷卻部的拉鏈鏈條施加張力。藉此，利用鏈條加熱部矯正為筆直的拉鏈鏈條一面維持其形態一面被冷卻，因此可固定該筆直的拉鏈鏈條的形態並穩定地保持。進而，亦可防止鏈牙列的鏈牙間隔於左右鏈牙列間偏移。因此，可去除捲曲傾向而獲得具有筆直的形態的經染色的拉鏈鏈條。In addition, in the correction device of the present invention, after the zipper chain is heated by the chain heating section, the heated zipper chain is cooled by the chain cooling section, and the zipper chain flowing through the chain cooling section is countered by the chain tension applying section. Apply tension. Thereby, the straight zipper chain corrected by the chain heating portion is cooled while maintaining its shape, so that the shape of the straight zipper chain can be fixed and stably maintained. Furthermore, it is possible to prevent the elements in the element rows from being shifted between the left and right element rows. Therefore, the tendency to curl can be removed to obtain a dyed zipper chain having a straight form.

進而，本發明中，由於對流經鏈條冷卻部的拉鏈鏈條施加固定大小的張力，因此拉鏈鏈條的熱收縮量受到限制，從而可遍及整個帶長度方向將左右鏈牙列中的鏈牙間隔調整為固定大小。藉此，減小左右鏈牙列間的尺寸的偏差或左右鏈牙列的帶長度方向上的尺寸的偏差，而遍及整個拉鏈鏈條使鏈牙列的尺寸穩定，因此可提高拉鏈鏈條的尺寸精度。Furthermore, in the present invention, since a fixed amount of tension is applied to the zipper chain flowing through the chain cooling section, the amount of heat shrinkage of the zipper chain is limited, so that the interval between the elements in the left and right element rows can be adjusted throughout the length of the belt to Fixed size. Thereby, the size deviation between the left and right fastener element rows or the size deviation of the left and right fastener element strips in the length direction is reduced, and the size of the fastener element rows is stabilized throughout the entire zipper chain, thereby improving the dimensional accuracy of the zipper chain. .

於此種本發明的矯正裝置中，於鏈條供給部與鏈條搬送部之間配置使拉鏈鏈條的搬送路徑呈鋸齒狀曲折前進的多個導引輥。藉此，可穩定地確保拉鏈鏈條的搬送路徑的長度，同時可實現矯正裝置的小型化。In such a correction device of the present invention, a plurality of guide rollers are provided between the chain supply section and the chain conveyance section to make the conveyance path of the zipper chain meander in a zigzag manner. This makes it possible to stably secure the length of the conveying path of the fastener chain, and to reduce the size of the correction device.

另外，於該情況下，將於鏈條加熱部中所搬送的拉鏈鏈條的搬送距離設定為短於在鏈條冷卻部中所搬送的拉鏈鏈條的搬送距離。如此般將鏈條加熱部的搬送距離設定為短於鏈條冷卻部的搬送距離而高效地進行利用鏈條加熱部的拉鏈鏈條的加熱，藉此可實現矯正裝置的進一步小型化。進而，藉由利用搬送路徑短的鏈條加熱部將拉鏈鏈條的形態延伸為筆直，於結果上可縮短將拉鏈鏈條在彎曲狀的產生有捲曲傾向的狀態下搬送的距離，因此可使拉鏈鏈條的搬送進一步穩定。In this case, the conveying distance of the zipper chain conveyed in the chain heating section is set to be shorter than the conveying distance of the zipper chain conveyed in the chain cooling section. In this way, by setting the conveying distance of the chain heating section to be shorter than the conveying distance of the chain cooling section and efficiently heating the zipper chain using the chain heating section, further miniaturization of the correction device can be achieved. Furthermore, the shape of the zipper chain is extended straight by the chain heating section with a short conveying path. As a result, the distance that the zipper chain can be transported in a curved state with a tendency to curl can be shortened. Transport is further stabilized.

另外，藉由使鏈條冷卻部的搬送距離長於鏈條加熱部的搬送距離，可於鏈條冷卻部中一面對經加熱的拉鏈鏈條施加張力一面緩慢地（緩慢而細致地）冷卻。因此，可防止拉鏈帶及鏈牙列急劇收縮，且可使拉鏈帶及鏈牙列的熱收縮量更難以產生偏差。In addition, by making the conveying distance of the chain cooling section longer than that of the chain heating section, the chain cooling section can be slowly (slowly and carefully) cooled while applying tension to the heated zipper chain. Therefore, it is possible to prevent the shrinkage of the fastener tape and the fastener element row from rapidly contracting, and it is possible to make the heat shrinkage of the fastener tape and the fastener element row less likely to vary.

於該情況下，鏈條加熱部具有夾配於曲折前進的搬送路徑的熱源。藉此，於搬送距離短的鏈條加熱部中，可利用該熱源高效且穩定地對拉鏈鏈條進行加熱。另外，可緊湊地集中熱源的設置空間，且可實現省空間化。進而，鏈條加熱部的熱源形成為可以30℃/min以上的升溫速度對拉鏈鏈條進行加熱。藉此，可利用搬送距離短的鏈條加熱部將拉鏈鏈條穩定且迅速地加熱至規定的溫度。In this case, the chain heating section has a heat source that is sandwiched between the zigzag conveying path. Thereby, in the chain heating section with a short conveying distance, the heat source can be used to efficiently and stably heat the zipper chain. In addition, the installation space of the heat source can be compactly concentrated, and space saving can be achieved. Furthermore, the heat source of the chain heating part is formed so that the fastener chain can be heated at a temperature rising rate of 30 ° C./min or more. Accordingly, the chain heating unit with a short conveying distance can stably and quickly heat the zipper chain to a predetermined temperature.

尤其，藉由鏈條加熱部的熱源為板狀的紅外線加熱器（遠紅外線加熱器），可以簡單的結構形成鏈條加熱部，並且可穩定地進行鏈條加熱部中的拉鏈鏈條的加熱。再者，作為鏈條加熱部的熱源，例如亦可利用電阻加熱等。In particular, since the heat source of the chain heating portion is a plate-shaped infrared heater (far infrared heater), the chain heating portion can be formed with a simple structure, and the zipper chain in the chain heating portion can be heated stably. In addition, as a heat source of the chain heating section, for example, resistance heating can be used.

另外，於本發明的矯正裝置中，鏈條加熱部形成為可將拉鏈鏈條加熱至形成該拉鏈鏈條的拉鏈鏈牙的合成樹脂的玻璃轉移溫度以上且120℃以下的溫度。In the correction device of the present invention, the chain heating portion is formed so as to heat the zipper chain to a temperature higher than or equal to 120 ° C and a glass transition temperature of the synthetic resin forming the fastener elements of the fastener chain.

藉由利用鏈條加熱部將拉鏈鏈條加熱至拉鏈鏈牙的玻璃轉移溫度以上，可矯正左右鏈牙列而使鏈牙間隔穩定地一致。尤其，於該情況下，藉由利用鏈條加熱部將拉鏈鏈條加熱至形成拉鏈帶的合成纖維的玻璃轉移溫度以上，可於鏈條加熱部中將產生有捲曲傾向的拉鏈鏈條進一步穩定地延伸為筆直的形態。By heating the zipper chain to a temperature higher than the glass transition temperature of the zipper elements by the chain heating portion, the left and right element rows can be corrected and the element intervals can be stably uniform. In this case, in particular, by heating the zipper chain to a temperature higher than the glass transition temperature of the synthetic fiber forming the zipper tape by the chain heating portion, the zipper chain having a tendency to curl can be further stably extended straight in the chain heating portion. Shape.

另一方面，藉由於鏈條加熱部中將拉鏈鏈條加熱至120℃以下的溫度，可防止於使用超臨界流體而染色的拉鏈鏈條中產生褪色，並且亦可防止拉鏈鏈條的染色牢固度因鏈條加熱部的加熱而降低。On the other hand, by heating the zipper chain to a temperature below 120 ° C in the chain heating portion, it is possible to prevent discoloration in the zipper chain dyed with a supercritical fluid, and also prevent the dyeing fastness of the zipper chain from being heated by the chain. The heating of the part decreases.

進而，於本發明的矯正裝置中，鏈條冷卻部形成為可一面搬送拉鏈鏈條，一面藉由自然空氣冷卻而至少冷卻至玻璃轉移溫度以下。藉此，可利用鏈條冷卻部將拉鏈鏈條緩慢且穩定地冷卻，且可使拉鏈帶及鏈牙列的熱收縮量更難以產生偏差。另外，亦可抑制設備成本的增大。Furthermore, in the correction device of the present invention, the chain cooling section is formed so that the zipper chain can be transported while being cooled by natural air and at least cooled to a temperature below the glass transition temperature. Thereby, the zipper chain can be cooled slowly and stably by the chain cooling part, and the variation in the heat shrinkage of the zipper tape and the element row can be made less difficult. In addition, an increase in equipment cost can be suppressed.

另外，於本發明的矯正裝置中，鏈條張力施加部具有對拉鏈鏈條賦予荷重的張力調節輥。藉此，可簡單地形成鏈條張力施加部，並且可對流經鏈條加熱部及鏈條冷卻部的拉鏈鏈條穩定地施加規定的大小的張力。Moreover, in the correction apparatus of this invention, a chain tension application part has the tension adjustment roller which applies a load to a fastener chain. This makes it possible to simply form the chain tension applying portion, and to stably apply a predetermined magnitude of tension to the zipper chain passing through the chain heating portion and the chain cooling portion.

另外，於該情況下，張力調節輥配置於鏈條冷卻部中的搬送路徑的靠鏈條加熱部的位置，藉此難以受到鏈條加熱部的加熱的影響。進而，藉由張力調節輥配置於所述位置，可對流經鏈條冷卻部的拉鏈鏈條穩定地施加張力，並且亦可對流經鏈條加熱部的拉鏈鏈條穩定地施加張力。Moreover, in this case, since the tension adjustment roller is arrange | positioned by the chain heating part of the conveyance path in a chain cooling part, it is hard to be influenced by the heating of a chain heating part. Further, by disposing the tension adjusting roller at the position, tension can be stably applied to the zipper chain flowing through the chain cooling section, and tension can also be stably applied to the zipper chain flowing through the chain heating section.

繼而，由本發明提供的拉鏈用拉鏈鏈條的矯正方法中，供給產生有捲曲傾向的拉鏈鏈條並以規定的搬送速度進行搬送，並且一面利用鏈條加熱部對該拉鏈鏈條進行加熱，一面對流經該鏈條加熱部的拉鏈鏈條施加張力。藉此，可於鏈條加熱部的搬送路徑上，一面對拉鏈鏈條進行加熱一面延伸，而將拉鏈鏈條的形態形成為筆直，並且可於左右鏈牙列間使鏈牙間隔一致。Next, in the method for correcting a zipper chain for a slide fastener provided by the present invention, a zipper chain having a tendency to curl is supplied and conveyed at a predetermined conveying speed, and the zipper chain is heated by a chain heating section while flowing through Tension is applied to the zipper chain of the chain heating portion. Thereby, on the conveying path of the chain heating section, the zipper chain can be heated while being extended while facing the zipper chain, and the shape of the zipper chain can be formed straight, and the interval between the elements can be made uniform between the left and right element rows.

如上所述般利用鏈條加熱部對拉鏈鏈條進行加熱後，將該經加熱的拉鏈鏈條搬送至鏈條冷卻部，於鏈條冷卻部中，一面對拉鏈鏈條進行冷卻，一面對流經該鏈條冷卻部的拉鏈鏈條施加張力。藉此，利用鏈條加熱部矯正為筆直的拉鏈鏈條一面維持其形態一面被冷卻，因此可固定該筆直的拉鏈鏈條的形態並穩定地保持。進而，亦可防止鏈牙列的鏈牙間隔於左右鏈牙列間偏移。因此，可去除捲曲傾向而穩定地獲得具有筆直的形態的經染色的拉鏈鏈條。After the zipper chain is heated by the chain heating section as described above, the heated zipper chain is transported to the chain cooling section. In the chain cooling section, one side of the zipper chain is cooled, and the other side is cooled by flowing through the chain. Tension is applied to the zipper chain at the bottom. Thereby, the straight zipper chain corrected by the chain heating portion is cooled while maintaining its shape, so that the shape of the straight zipper chain can be fixed and stably maintained. Furthermore, it is possible to prevent the elements in the element rows from being shifted between the left and right element rows. Therefore, it is possible to stably obtain a dyed zipper chain having a straight form by removing the curl tendency.

進而，本發明中，藉由對流經鏈條冷卻部的拉鏈鏈條施加固定大小的張力，可遍及整個帶長度方向將左右鏈牙列中的鏈牙間隔調整為固定大小。藉此，減小左右鏈牙列間的尺寸的偏差或左右鏈牙列的帶長度方向上的尺寸的偏差，而可遍及整個拉鏈鏈條使鏈牙列的尺寸穩定，因此可提高拉鏈鏈條的尺寸精度。再者，於該情況下，亦可藉由改變對拉鏈鏈條施加的張力的大小來調整鏈牙列的鏈牙間隔。Furthermore, in the present invention, by applying a fixed amount of tension to the zipper chain passing through the chain cooling section, the interval between the elements in the left and right element rows can be adjusted to a fixed size throughout the length direction of the belt. This can reduce the size deviation between the left and right element rows or the size deviation of the left and right element rows in the belt length direction, and can stabilize the size of the element rows throughout the entire zipper chain, thereby increasing the size of the zipper chain. Precision. Furthermore, in this case, it is also possible to adjust the element interval of the element row by changing the amount of tension applied to the zipper chain.

於此種本發明的矯正方法中，藉由一面使拉鏈鏈條呈鋸齒狀曲折前進一面進行搬送，可穩定地確保拉鏈鏈條的搬送路徑的長度，同時可實現矯正裝置的小型化。In such a correction method of the present invention, the zipper chain is zigzagged forward while being conveyed while being conveyed, so that the length of the zipper chain conveying path can be stably secured, and the size of the correction device can be reduced.

另外，於該情況下，將於鏈條加熱部中所搬送的拉鏈鏈條的搬送距離設定為短於在鏈條冷卻部中所搬送的拉鏈鏈條的搬送距離，而高效地進行利用鏈條加熱部的拉鏈鏈條的加熱，藉此可使矯正裝置進一步小型化。進而，藉由縮短鏈條加熱部的搬送路徑並將拉鏈鏈條的形態延伸為筆直，於結果上可縮短將拉鏈鏈條在彎曲狀的產生有捲曲傾向的狀態下搬送的距離，因此可使拉鏈鏈條的搬送進一步穩定。In this case, the transfer distance of the zipper chain transferred in the chain heating section is set shorter than the transfer distance of the zipper chain transferred in the chain cooling section, and the zipper chain using the chain heating section is efficiently performed. Heating, which can further miniaturize the correction device. Furthermore, by shortening the conveying path of the chain heating section and extending the shape of the zipper chain straight, as a result, the distance that the zipper chain can be transported in a bent and curled state can be shortened. Transport is further stabilized.

另外，本發明的矯正方法中，於鏈條加熱部中，將拉鏈鏈條以30℃/min以上的升溫速度加熱至形成該拉鏈鏈條的拉鏈鏈牙的合成樹脂的玻璃轉移溫度以上且120℃以下的溫度。藉由以30℃/min以上的升溫速度對拉鏈鏈條進行加熱，可利用鏈條加熱部將拉鏈鏈條穩定且迅速地加熱至規定的溫度。另外，藉由利用鏈條加熱部將拉鏈鏈條加熱至拉鏈鏈牙的玻璃轉移溫度以上、進而將拉鏈鏈條加熱至形成拉鏈帶的合成纖維的玻璃轉移溫度以上，可將具有捲曲傾向的拉鏈鏈條進一步穩定地延伸為筆直的形態。另外，藉由利用鏈條加熱部將拉鏈鏈條加熱至120℃以下的溫度，可防止於使用超臨界流體而染色的拉鏈鏈條中產生褪色，並且亦可防止拉鏈鏈條的染色牢固度因鏈條加熱部的加熱而降低。In the correction method of the present invention, in the chain heating section, the zipper chain is heated at a temperature increase rate of 30 ° C./min or more to a glass transition temperature of the synthetic resin forming the zipper elements of the zipper chain above 120 ° C. temperature. By heating the zipper chain at a temperature rising rate of 30 ° C./min or more, the zipper chain can be stably and quickly heated to a predetermined temperature by the chain heating section. In addition, by heating the zipper chain to a temperature higher than the glass transition temperature of the fastener elements by the chain heating portion, and further heating the zipper chain to a temperature higher than the glass transition temperature of the synthetic fiber forming the zipper tape, the zipper chain having a tendency to curl can be further stabilized. The ground extends into a straight form. In addition, by using the chain heating section to heat the zipper chain to a temperature below 120 ° C, discoloration in the zipper chain dyed with a supercritical fluid can be prevented, and the fastness of dyeing of the zipper chain due to the chain heating section can be prevented. Reduced by heating.

進而，本發明的矯正方法中，於鏈條冷卻部中一面搬送拉鏈鏈條一面藉由自然空氣冷卻而至少冷卻至玻璃轉移溫度以下，藉此可利用鏈條冷卻部將拉鏈鏈條緩慢且穩定地冷卻，且可使拉鏈帶及鏈牙列的熱收縮量更難以產生偏差。Furthermore, in the correction method of the present invention, while the zipper chain is being transported in the chain cooling section, it is cooled to at least below the glass transition temperature by natural air cooling, whereby the zipper chain can be slowly and stably cooled by the chain cooling section, and This makes it more difficult for the heat shrinkage of the fastener tape and the element row to vary.

圖1是示意性地表示本實施例的矯正裝置的示意圖。於本實施例中，使用圖1的矯正裝置進行矯正處理的對象物是如圖3所示的彎曲狀的產生有捲曲傾向的染色後的拉鏈鏈條，其是由例如使用圖4所示的裝置對圖2所示的拉鏈（slide fastener）用拉鏈鏈條實施染色及清洗處理而得。FIG. 1 is a schematic view showing a correction device according to this embodiment. In this embodiment, the correction object using the correction device of FIG. 1 is a dyed zipper chain that is curved and has a tendency to curl as shown in FIG. 3. For example, the device shown in FIG. 4 is used. The slide fastener chain shown in FIG. 2 is obtained by dyeing and washing.

此處，圖2所示的拉鏈鏈條1具有左右一對的拉鏈牙鏈帶（fastener stringer）2，且形成於左右拉鏈牙鏈帶2的鏈牙列3相互咬合。另外，各拉鏈牙鏈帶2分別包括由聚酯纖維的織物形成的拉鏈帶（fastener tape）4、與縫合於拉鏈帶4的對向側緣部的線圈狀的多個拉鏈鏈牙5，且鏈牙列3由安裝於拉鏈帶4的多個拉鏈鏈牙5形成。Here, the zipper chain 1 shown in FIG. 2 includes a pair of left and right fastener stringers 2, and the element rows 3 formed on the left and right zipper chain 2 are engaged with each other. Each of the fastener element belts 2 includes a fastener tape 4 made of a polyester fiber fabric, and a plurality of coil-shaped fastener elements 5 stitched to the side edges of the opposite side of the fastener tape 4. The element row 3 is formed of a plurality of fastener elements 5 attached to the fastener tape 4.

於該情況下，拉鏈帶4具有縫合拉鏈鏈牙5的鏈牙安裝部、與自鏈牙安裝部的一側緣向帶寬度方向的外側延伸存在並縫接於衣服等拉鏈附著製品的帶主體部。In this case, the fastener tape 4 has a fastener element attaching portion for sewing the fastener element 5 and a belt body extending from the side edge of the fastener element attaching portion to the outside in the tape width direction and sewn to a zipper-attached product such as clothes. unit.

另外，多個拉鏈鏈牙5藉由將包含聚酯的單絲纖維呈線圈狀成形而呈連續狀形成，各拉鏈鏈牙5包括：咬合頭部；上下腳部，自咬合頭部向帶寬度方向延伸出；連結部，將上腳部或下腳部的端部與鄰接於前後的鏈牙的下腳部或上腳部連結。此種線圈狀的拉鏈鏈牙5在使芯繩插通於上下腳部間的狀態下，設為使咬合頭部自拉鏈帶4的鏈牙安裝部側的帶側緣向外方突出，並藉由縫製絲6的雙線包縫（two-thread overcasting stitch）而縫接於鏈牙安裝部。In addition, the plurality of fastener elements 5 are formed continuously by forming a monofilament fiber containing polyester in a coil shape, and each fastener element 5 includes a bite head, upper and lower feet, and a width from the bite head to the belt. Extending in the direction; a connecting portion that connects an end portion of the upper leg portion or the lower leg portion with the lower leg portion or the upper leg portion of the front and rear adjacent elements. The coil-shaped fastener element 5 is configured such that the bite head protrudes outward from the belt side edge of the fastener element mounting portion side of the fastener tape 4 in a state where the core rope is inserted between the upper and lower legs, and The two-thread overcasting stitch of the sewing wire 6 is sewn to the element attachment portion.

於使用圖4所示的染色×清洗裝置100對此種拉鏈鏈條1進行利用超臨界流體（超臨界二氧化碳）的染色處理的情況下，如上所述，首先，將長條的拉鏈鏈條1捲繞於未圖示的滾筒，將拉鏈鏈條1連同該滾筒與染料一起收容於高壓釜111內。此時，拉鏈鏈條1中的左右鏈牙列3自拉鏈帶4的帶表面膨出，因此，於滾筒上，拉鏈鏈條1一面呈螺旋狀在軸方向上錯開位置，一面藉由橫向捲繞而捲繞於其上。In a case where the zipper chain 1 is dyed with a supercritical fluid (supercritical carbon dioxide) using the dyeing × washing device 100 shown in FIG. 4, as described above, first, the long zipper chain 1 is wound. The zipper chain 1 is stored in an autoclave 111 together with the drum and the dye in a drum (not shown). At this time, the left and right element rows 3 in the zipper chain 1 bulge from the belt surface of the zipper tape 4. Therefore, on the drum, the zipper chain 1 is spirally staggered in the axial direction, and is wound horizontally. Wind it up.

將拉鏈鏈條1及染料收容於高壓釜111內後，如上所述，將超臨界二氧化碳自供給單元120供給至染色×清洗單元110。進而，驅動染色×清洗單元110的循環泵113，而使超臨界二氧化碳於循環路徑112及高壓釜111中循環，並且利用溫度控制部115及壓力控制部116對高壓釜111內的溫度及壓力進行控制。藉此，將在捲繞於滾筒的狀態下收容於高壓釜111內的拉鏈鏈條1染色。After the zipper chain 1 and the dye are stored in the autoclave 111, supercritical carbon dioxide is supplied from the supply unit 120 to the dyeing × washing unit 110 as described above. Further, the circulation pump 113 of the dyeing / washing unit 110 is driven to circulate supercritical carbon dioxide in the circulation path 112 and the autoclave 111, and the temperature and pressure in the autoclave 111 are controlled by the temperature control unit 115 and the pressure control unit 116. control. Thereby, the fastener chain 1 accommodated in the autoclave 111 in the state wound by the drum is dyed.

染色處理進行規定時間而結束後，連續地進行清洗處理。該清洗處理中，如上所述，使於高壓釜111及循環路徑112中循環的超臨界二氧化碳中的染料的濃度隨時間經過而逐漸減少，並且一面使高壓釜111內的溫度以規定的降溫速度降低至玻璃轉移溫度以下，一面利用該超臨界二氧化碳進行纖維製品或高壓釜111的清洗處理。After the dyeing process is completed for a predetermined time, the washing process is continuously performed. In this cleaning process, as described above, the concentration of the dye in the supercritical carbon dioxide circulating in the autoclave 111 and the circulation path 112 is gradually reduced with the passage of time, and the temperature in the autoclave 111 is reduced at a predetermined rate While reducing the temperature below the glass transition temperature, the supercritical carbon dioxide is used to perform cleaning treatment on the fiber product or the autoclave 111.

藉此，抑制染色於拉鏈鏈條1的顏色脫落，同時可清洗纖維製品及高壓釜111。於該情況下，在拉鏈鏈條1呈螺旋狀捲繞於滾筒的狀態下，藉由圖4所示的染色×清洗裝置100進行染色×清洗處理，因此對染色處理及清洗處理後所獲得的拉鏈鏈條1進行乾燥，且該拉鏈鏈條1因染色處理後的熱收縮而產生有如圖3所示般彎曲的偏置形狀的捲曲傾向。Thereby, it is possible to suppress the color drop of the dyed zipper chain 1 and clean the fiber product and the autoclave 111 at the same time. In this case, in a state where the zipper chain 1 is spirally wound around the drum, the dyeing × washing device 100 shown in FIG. 4 is used to perform the dyeing × washing treatment. Therefore, the zipper obtained after the dyeing treatment and the washing treatment is performed. The chain 1 is dried, and the zipper chain 1 has a tendency to curl in an offset shape that is curved as shown in FIG. 3 due to heat shrinkage after the dyeing process.

再者，拉鏈鏈條1對應於將拉鏈鏈條1呈螺旋狀捲繞於滾筒的朝向而具有如圖3所示的朝左彎曲的捲曲傾向或其相反的朝右彎曲的捲曲傾向。另外，例如當將拉鏈鏈條1呈螺旋狀捲繞於滾筒時，於將拉鏈鏈條1交替地進行如下捲繞方式的情況下，拉鏈鏈條1交替地形成朝左彎曲的捲曲傾向與朝右彎曲的捲曲傾向，所述捲繞方式為一面在滾筒的軸方向的一方向（例如上方）錯開一面呈螺旋狀捲繞的捲繞方式、與一面在滾筒的軸方向的另一方向（例如下方）錯開一面呈螺旋狀捲繞的捲繞方式。Note that the zipper chain 1 has a curl tendency to bend to the left as shown in FIG. 3 or an opposite curl tendency to bend to the right corresponding to the direction in which the zipper chain 1 is spirally wound around the drum. In addition, for example, when the zipper chain 1 is wound spirally on a drum, when the zipper chain 1 is alternately wound as follows, the zipper chain 1 alternately forms a curling tendency bent to the left and a bent tendency to the right. Curl tendency, the winding method is a winding method in which one side is staggered in one direction of the axial direction of the drum (for example, upward), and a winding direction is staggered in another direction (for example, downward) in the axial direction of the roller. A winding method in which one side is spirally wound.

再者，所述染色處理或清洗處理只不過僅為用以說明因超臨界流體的染色處理而於拉鏈鏈條1中產生有捲曲傾向的一例。本發明的目的在於在如下情況下，使用以下所說明的矯正裝置10來去除該拉鏈鏈條1的捲曲傾向，所述情況為藉由在拉鏈鏈條1呈螺旋狀捲繞於滾筒的狀態下進行超臨界流體的染色處理而於拉鏈鏈條1中產生有因捲繞於滾筒所造成的捲曲傾向。因此，本發明中，對拉鏈鏈條1實施的使用超臨界流體的染色處理或其後的清洗處理中的具體方法或條件等並不特別限定。It should be noted that the dyeing process or the washing process is merely an example for explaining the tendency of curling in the zipper chain 1 due to the dyeing process of the supercritical fluid. The object of the present invention is to remove the curl tendency of the zipper chain 1 by using the correction device 10 described below in the case where the zipper chain 1 is spirally wound around a roller in a state where the zipper chain 1 is spirally wound. The critical fluid dyeing process causes the zipper chain 1 to have a tendency to curl due to being wound around a roller. Therefore, in the present invention, specific methods or conditions in the dyeing process using a supercritical fluid or the subsequent washing process performed on the fastener chain 1 are not particularly limited.

With this plate-shaped infrared heater 42, the zipper chain 1, which flows downward from the first guide roller 11a toward the second guide roller 11b, and the third guide roller 11c from the second guide roller 11b The zipper chain 1 flowing upward is heated.

使用此種板狀的紅外線加熱器42，藉此可效率良好地加熱至拉鏈鏈牙5的內部。另外，由於可將紅外線加熱器42在夾於上下往返的搬送路徑的狀態下設置得細長，故可將自第1導引輥11a經由第2導引輥11b而流動至第3導引輥11c的拉鏈鏈條1穩定地加熱至規定的溫度。By using such a plate-shaped infrared heater 42, the inside of the fastener element 5 can be efficiently heated. In addition, since the infrared heater 42 can be provided in a long and thin state while being sandwiched between the up and down transport path, it can flow from the first guide roller 11a to the third guide roller 11c through the second guide roller 11b. The zipper chain 1 is stably heated to a predetermined temperature.

進而，本實施例中，可將鏈條加熱部40設置於狹小的空間，且可實現鏈條加熱部40的省空間化或矯正裝置10整體的省空間化。再者，本發明中，亦可代替紅外線加熱器42而使用中波長碳加熱器作為鏈條加熱部40的熱源。Furthermore, in this embodiment, the chain heating section 40 can be installed in a small space, and the space saving of the chain heating section 40 or the space saving of the entire correction device 10 can be achieved. Furthermore, in the present invention, a medium-wavelength carbon heater may be used as a heat source of the chain heating section 40 instead of the infrared heater 42.

於該情況下，鏈條加熱部40形成為可藉由紅外線加熱器42而進行拉鏈鏈條1的加熱，以使拉鏈鏈條1的溫度（尤其拉鏈鏈牙5的溫度）在將拉鏈鏈條1自外殼部41搬出時，至少成為作為拉鏈鏈牙5的材質的聚酯的玻璃轉移溫度（70℃）以上、且於經染色的拉鏈鏈條1中難以產生因加熱所造成的褪色的120℃以下。另外，鏈條加熱部40形成為可藉由紅外線加熱器42而以30℃/min以上的升溫速度對拉鏈鏈條1進行加熱。藉此，可將拉鏈鏈條1穩定且迅速地加熱至規定的溫度。In this case, the chain heating portion 40 is formed so that the zipper chain 1 can be heated by the infrared heater 42 so that the temperature of the zipper chain 1 (especially the temperature of the zipper element 5) is such that the zipper chain 1 is removed from the outer shell portion. At the time of carrying out 41, at least the glass transition temperature (70 ° C) of the polyester which is the material of the fastener element 5 is 120 ° C or lower at which the discoloration of the dyed fastener chain 1 due to heating is unlikely to occur. In addition, the chain heating section 40 is formed so that the fastener chain 1 can be heated by the infrared heater 42 at a temperature increase rate of 30 ° C./min or more. Thereby, the fastener chain 1 can be heated stably and quickly to a predetermined temperature.

鏈條冷卻部50設置於鏈條加熱部40與鏈條搬送部30之間。該鏈條冷卻部50中，自第4導引輥11d至第17導引輥11q呈鋸齒狀流動的拉鏈鏈條1藉由自然空氣冷卻（自然冷卻）而冷卻。此處，所謂自然空氣冷卻，是指在未利用風扇機等來產生強制性的風的狀態下，一面將拉鏈鏈條1暴露於常溫的空氣中一面進行搬送，藉此進行冷卻，且不進行使拉鏈鏈條1通過低於常溫的冷氣內或對拉鏈鏈條1吹附冷氣等。The chain cooling section 50 is provided between the chain heating section 40 and the chain transfer section 30. In this chain cooling unit 50, the zipper chain 1 flowing in a zigzag manner from the fourth guide roller 11d to the 17th guide roller 11q is cooled by natural air cooling (natural cooling). Here, the natural air cooling means that the zip chain 1 is transported while being exposed to the air at normal temperature in a state where a forced wind is not generated by using a fan or the like, and cooling is performed without performing cooling. The zipper chain 1 passes through the cold air at a temperature lower than normal temperature, or blows air to the zipper chain 1.

若如此般鏈條冷卻部50為進行拉鏈鏈條1的自然空氣冷卻者，則可以簡單的結構形成鏈條冷卻部50，且可抑制設備成本的增大。於該情況下，鏈條冷卻部50中，對應於拉鏈鏈條1的搬送速度，鏈條搬送路徑以可藉由自然空氣冷卻將拉鏈鏈條1冷卻至玻璃轉移溫度以下、較佳為常溫（例如30℃以下）的長度形成。If the chain cooling section 50 is a natural air cooler for the zipper chain 1 in this way, the chain cooling section 50 can be formed with a simple structure, and an increase in equipment cost can be suppressed. In this case, in the chain cooling section 50, the chain conveying path can cool the zipper chain 1 below the glass transition temperature, preferably normal temperature (for example, 30 ° C or lower) by natural air cooling in accordance with the conveying speed of the zipper chain 1. ) Length formed.

鏈條張力施加部60具有與拉鏈鏈條1接觸且旋轉的一個張力調節輥61。該張力調節輥61以重物的形式對拉鏈鏈條1賦予荷重，因此於鏈條冷卻部50中的拉鏈鏈條1的曲折前進的搬送路徑中，配置於下側的折返端部的位置。The chain tension applying portion 60 includes one tension adjusting roller 61 that is in contact with the fastener chain 1 and rotates. Since the tension adjustment roller 61 applies a load to the zipper chain 1 as a weight, the tension adjusting roller 61 is arranged at a position of the lower folding end portion in the zigzag forward conveying path of the zipper chain 1 in the chain cooling section 50.

張力調節輥61如上所述般配置，藉此可對自拉鏈鏈條1中的被供給輥部22的驅動供給輥22a及供給壓接輥夾持的部分起至被鏈條搬送部30的驅動搬送輥32及搬送壓接輥夾持的部分的整體穩定地賦予延伸拉鏈鏈條1的方向的張力。The tension adjusting roller 61 is arranged as described above, so that it can be driven from the portion between the driving supply roller 22a and the supply crimping roller of the zipper chain 1 to be driven by the supply roller portion 22 to the driving transportation roller of the chain transportation portion 30. The entirety of 32 and the portion held by the transfer crimping roller stably imparts tension in the direction in which the fastener chain 1 is extended.

再者，該鏈條張力施加部60中，可藉由改變張力調節輥61的重量來改變拉鏈鏈條1所受到的張力的大小，例如，本實施例中，藉由張力調節輥61而對拉鏈鏈條1施加2 kg以上的荷重、較佳為4 kg以上的荷重。Moreover, in the chain tension applying part 60, the magnitude of the tension experienced by the zipper chain 1 can be changed by changing the weight of the tension adjustment roller 61. For example, in this embodiment, the zipper chain is adjusted by the tension adjustment roller 61. 1 Apply a load of 2 kg or more, preferably a load of 4 kg or more.

另外，本實施例中，張力調節輥61配置於流經鏈條冷卻部50的拉鏈鏈條1的搬送路徑上的靠鏈條加熱部40的位置。若進一步具體說明，則本實施例的張力調節輥61於鏈條冷卻部50中配置於上下往返的七個往返路徑中的最靠鏈條加熱部40的往返路徑（即，鏈條加熱部40之後於最先通過的第4導引輥11d與下一第5導引輥11e之間所形成的往返路徑）中的下側的折返端部。Moreover, in this embodiment, the tension adjustment roller 61 is arrange | positioned by the chain heating part 40 on the conveyance path of the fastener chain 1 which passes through the chain cooling part 50. If it is further described in detail, the tension adjusting roller 61 of this embodiment is arranged in the chain cooling section 50 among the seven round-trip paths that are up and down and which are closest to the chain heating section 40 (that is, the chain heating section 40 The lower end of the turn-back path in the reciprocating path formed between the fourth guide roller 11d that passed first and the next fifth guide roller 11e).

張力調節輥61配置於所述鏈條冷卻部50的區域，藉此難以受到利用鏈條加熱部40的紅外線加熱器42的加熱的影響，因此可提高張力調節輥61的耐久性。Since the tension adjusting roller 61 is disposed in the region of the chain cooling section 50, the tension adjusting roller 61 is hardly affected by the heating by the infrared heater 42 of the chain heating section 40. Therefore, the durability of the tension adjusting roller 61 can be improved.

進而，張力調節輥61配置於鏈條冷卻部50的區域中的最靠鏈條加熱部40的拉鏈鏈條1的往返路徑，藉此利用該張力調節輥61，不僅可對流經鏈條冷卻部50的拉鏈鏈條1與流經鏈條加熱部40的拉鏈鏈條1穩定地施加張力，而且可對流經鏈條加熱部40的拉鏈鏈條1進一步有效地施加大的張力。藉由如此般對流經鏈條加熱部40的拉鏈鏈條1施加大的張力，可高效地延伸經加熱的拉鏈鏈條1而將彎曲狀的拉鏈鏈條1於更早的階段恢復為筆直的形態。Furthermore, the tension adjusting roller 61 is arranged in the back-and-forth path of the zipper chain 1 closest to the chain heating section 40 in the region of the chain cooling section 50. By using the tension adjusting roller 61, not only the zipper chain flowing through the chain cooling section 50 can be used 1 and the zipper chain 1 flowing through the chain heating portion 40 are stably applied with tension, and a large tension can be further effectively applied to the zipper chain 1 flowing through the chain heating portion 40. By applying a large tension to the zipper chain 1 flowing through the chain heating portion 40 in this manner, the heated zipper chain 1 can be efficiently extended to return the curved zipper chain 1 to a straight shape at an earlier stage.

再者，於本發明中，鏈條張力施加部60亦可並非具有如上所述的張力調節輥61者，例如可為具有與拉鏈鏈條接觸且旋轉並且可在上下方向上位移的接觸輥、與藉由控制該接觸輥的高度位置而可對拉鏈鏈條1賦予規定的荷重的高度位置控制部者。Furthermore, in the present invention, the chain tension applying portion 60 may not have the tension adjusting roller 61 as described above. For example, the chain tension applying portion 60 may be a contact roller that is in contact with the zipper chain and rotates and can be displaced in the vertical direction. A height position control unit that can apply a predetermined load to the fastener chain 1 by controlling the height position of the touch roller.

鏈條回收部70由上端部開口的方柱狀或圓柱狀的箱體形成。該鏈條回收部70配置於鏈條搬送部30的下方，藉此使自鏈條搬送部30排出的拉鏈鏈條1以自身的重量落下，藉此可簡單地回收通過鏈條加熱部40及鏈條冷卻部50的拉鏈鏈條1。The chain recovery part 70 is formed by a rectangular columnar or cylindrical box body whose upper end portion is opened. The chain recovery section 70 is disposed below the chain transfer section 30, so that the zipper chain 1 discharged from the chain transfer section 30 falls by its own weight, and thus the chain passing through the chain heating section 40 and the chain cooling section 50 can be easily recovered. Zipper chain 1.

繼而，針對如下方法進行說明：使用如上所述的本實施例的矯正裝置10，對如圖3所示的彎曲狀的具有捲曲傾向的拉鏈鏈條1進行矯正拉鏈鏈條1的形態的矯正處理。於本實施例中，產生有捲曲傾向的拉鏈鏈條1如此般捲繞於滾筒8，另外，該滾筒8保持於矯正裝置10的滾筒保持部21。Next, a method for correcting the shape of the zipper chain 1 by using the correction device 10 of the present embodiment as described above to correct the shape of the zipper chain 1 with a tendency to curl as shown in FIG. 3 will be described. In this embodiment, the zipper chain 1 having a tendency to curl is wound around the drum 8 in this manner, and the drum 8 is held by the drum holding portion 21 of the correction device 10.

因此，當進行拉鏈鏈條1的矯正處理時，首先，藉由使供給輥部22的驅動供給輥22a以規定的旋轉速度旋轉驅動，而自滾筒8連續地抽出拉鏈鏈條1，並將該拉鏈鏈條1經由供給部導引輥23傳送至鏈條加熱部40及鏈條冷卻部50。Therefore, when performing the correction process of the zipper chain 1, first, the zipper chain 1 is continuously pulled out from the drum 8 by rotating the driving supply roller 22a of the supply roller portion 22 at a predetermined rotation speed, and the zipper chain 1 is pulled out. 1 is conveyed to the chain heating part 40 and the chain cooling part 50 via the supply part guide roller 23.

另外，同時使鏈條搬送部30的驅動搬送輥32以規定的旋轉速度旋轉驅動，藉此利用鏈條搬送部30引進自鏈條供給部20供給的拉鏈鏈條1。藉此，將拉鏈鏈條1自供給輥部22至鏈條搬送部30沿藉由第1導引輥11a～第17導引輥11q與張力調節輥61所形成的鋸齒狀的搬送路徑以規定的搬送速度進行搬送。進而，此時，藉由鏈條張力施加部60的張力調節輥61對自鏈條供給部20搬送至鏈條搬送部30的拉鏈鏈條1施加規定的大小的張力（tension）。At the same time, the driving and conveying roller 32 of the chain conveying section 30 is rotated and driven at a predetermined rotation speed, whereby the zipper chain 1 supplied from the chain supplying section 20 is introduced by the chain conveying section 30. Thereby, the zipper chain 1 is conveyed from the supply roller portion 22 to the chain conveyance portion 30 along a sawtooth-shaped conveyance path formed by the first guide rollers 11a to 17th guide rollers 11q and the tension adjustment roller 61 at a predetermined conveyance. Speed to carry. Furthermore, at this time, a tension of a predetermined magnitude is applied to the zipper chain 1 transferred from the chain supply section 20 to the chain transfer section 30 by the tension adjustment roller 61 of the chain tension application section 60.

再者，當開始利用該矯正裝置10的矯正處理時，預先將暫設的帶體或拉鏈鏈條沿鋸齒狀的搬送路徑自鏈條供給部20架設至鏈條搬送部30，並且將帶有捲曲傾向的拉鏈鏈條1的前端連接於該虛設的帶體的後端。藉此，使供給輥部22的驅動供給輥22a與鏈條搬送部30的驅動搬送輥32旋轉驅動，藉此可緊接著虛設的帶體而將拉鏈鏈條1沿鋸齒狀的搬送路徑穩定地搬送，且可對整個拉鏈鏈條1的長度方向進行矯正處理。Furthermore, when the correction process using the correction device 10 is started, a temporary belt body or a zipper chain is set in advance from the chain supply section 20 to the chain transport section 30 along a zigzag conveying path, and The front end of the zipper chain 1 is connected to the rear end of the dummy belt body. Thereby, the drive supply roller 22a of the supply roller section 22 and the drive conveyance roller 32 of the chain conveyance section 30 are rotationally driven, so that the zipper chain 1 can be stably conveyed along the zigzag conveyance path immediately after the dummy belt body. And the longitudinal direction of the entire zipper chain 1 can be corrected.

繼而，自供給輥部22供給的拉鏈鏈條1通過供給部導引輥23及第1導引輥11a而導入至鏈條加熱部40的外殼部41內。此時，為了對拉鏈鏈牙5高效地加熱，而將拉鏈鏈條1以按照鏈牙列3與紅外線加熱器42相對向的朝向進行往返的方式搬送至外殼部41內。Then, the zipper chain 1 supplied from the supply roller portion 22 is introduced into the housing portion 41 of the chain heating portion 40 through the supply portion guide roller 23 and the first guide roller 11 a. At this time, in order to efficiently heat the fastener elements 5, the fastener chain 1 is transported into the housing portion 41 so as to reciprocate in a direction in which the element rows 3 and the infrared heater 42 face each other.

另外，於鏈條加熱部40的外殼部41內，拉鏈鏈條1在藉由張力調節輥61而被施加張力的狀態下，以沿藉由第1導引輥11a～第3導引輥11c所形成的搬送路徑在上下方向上一往返的方式流動，並且藉由夾配於該往返的搬送路徑的板狀的紅外線加熱器42而被加熱。In addition, in the case portion 41 of the chain heating portion 40, the zipper chain 1 is formed along the first guide roller 11a to the third guide roller 11c in a state where tension is applied by the tension adjustment roller 61. The conveying path in the direction of one-round reciprocation flows in the up-and-down direction, and is heated by a plate-shaped infrared heater 42 sandwiched by the reciprocating conveying path.

此時，拉鏈鏈條1藉由紅外線加熱器42而加熱，以使拉鏈鏈條1自外殼部41搬出時的拉鏈鏈牙5的溫度至少成為作為拉鏈鏈牙5的材質的聚酯的玻璃轉移溫度（70℃）以上且120℃以下，較佳為成為80℃以上且110℃以下。At this time, the zipper chain 1 is heated by the infrared heater 42 so that the temperature of the zipper element 5 when the zipper chain 1 is carried out from the housing portion 41 becomes at least the glass transition temperature of polyester as the material of the zipper element 5 ( 70 ° C or higher and 120 ° C or lower, preferably 80 ° C or higher and 110 ° C or lower.

於該情況下，紅外線加熱器42的溫度設定為高於經加熱的拉鏈鏈牙5的溫度。另外，經加熱的拉鏈鏈牙5的溫度例如可使用利用雷射的非接觸式的溫度計來測定。In this case, the temperature of the infrared heater 42 is set higher than the temperature of the heated fastener element 5. The temperature of the heated fastener element 5 can be measured using, for example, a non-contact thermometer using a laser.

如上所述，拉鏈鏈條1於鏈條加熱部40的外殼部41內，在施加有張力的狀態下，藉由紅外線加熱器42而加熱至70℃以上的規定的溫度，藉此可延伸彎曲狀的拉鏈鏈條1而消除（或減小）拉鏈帶4的應變（翹曲），從而矯正為筆直的形態。另外，藉此，可於左右的鏈牙列3間使大小不同的鏈牙間隔彼此一致。As described above, the zipper chain 1 can be stretched into a curved shape by being heated to a predetermined temperature of 70 ° C. or higher by the infrared heater 42 under tension in the case portion 41 of the chain heating portion 40. The zipper chain 1 eliminates (or reduces) the strain (warping) of the zipper tape 4 and corrects it to a straight shape. In addition, by this, it is possible to make the intervals of the elements of different sizes between the left and right element rows 3 coincide with each other.

進而，藉由將拉鏈鏈條1的加熱溫度設為120℃以下，可有效地防止經染色的拉鏈鏈條1因加熱而褪色或拉鏈鏈條1的染色牢固度降低，另外，亦可防止拉鏈鏈牙5的形狀因加熱而崩塌。Furthermore, by setting the heating temperature of the zipper chain 1 to 120 ° C. or lower, the dyed zipper chain 1 can be effectively prevented from discoloring due to heating or the dyeing fastness of the zipper chain 1 is reduced, and the zipper element 5 can also be prevented. The shape collapsed by heating.

尤其，本實施例中，在以上下一往返的短的搬送距離搬送期間，利用紅外線加熱器42例如以30℃/min以上的升溫速度高效地對拉鏈鏈條1加熱，藉此可將拉鏈鏈條1迅速地加熱至規定的溫度，並且可於相對較早的階段將拉鏈鏈條1的形態延伸為筆直。藉此，於結果上可縮短將拉鏈鏈條1自供給輥部22以彎曲狀態搬送的距離，因此可使拉鏈鏈條1的搬送進一步穩定。In particular, in the present embodiment, the zipper chain 1 can be efficiently heated by the infrared heater 42 at a temperature raising rate of 30 ° C./min or more during the short transfer distance of the previous and next rounds, whereby the zipper chain 1 can be heated. It is quickly heated to a predetermined temperature, and the shape of the zipper chain 1 can be extended straight at a relatively early stage. As a result, the distance that the zipper chain 1 can be transported in a bent state from the supply roller portion 22 can be shortened as a result, so that the transportation of the zipper chain 1 can be further stabilized.

繼而，鏈條加熱部40中延伸為筆直的拉鏈鏈條1通過第3導引輥11c及第4導引輥11d後被搬送至鏈條冷卻部50並加以冷卻。鏈條冷卻部50中，拉鏈鏈條1一面沿藉由第4導引輥11d～第17導引輥11q與張力調節輥61所形成的上下呈鋸齒狀七往返的搬送路徑搬送，一面在利用張力調節輥61施加張力的狀態下，藉由自然空氣冷卻而至少冷卻至玻璃轉移溫度以下。於該情況下，拉鏈鏈條1較佳為利用鏈條冷卻部50以大於0℃/min且60℃/min以下的冷卻速度進行冷卻。Then, the zipper chain 1 extending straight in the chain heating section 40 passes through the third guide roller 11c and the fourth guide roller 11d, and is then transported to the chain cooling section 50 and cooled. In the chain cooling unit 50, the zipper chain 1 is conveyed along the up-and-down zigzag seven-return conveyance path formed by the fourth guide rollers 11d to 17d guide rollers 11q and the tension adjustment roller 61, while tension adjustment is being used. In a state where the roller 61 is under tension, it is cooled to at least the glass transition temperature by cooling with natural air. In this case, the fastener chain 1 is preferably cooled by the chain cooling section 50 at a cooling rate of more than 0 ° C./min and 60 ° C./min or less.

本實施例的鏈條冷卻部50中，一面以上下七往返的長的搬送距離搬送拉鏈鏈條1，一面在施加有張力的狀態下，藉由自然空氣冷卻而緩慢地（緩慢而細致地）冷卻，因此可抑制拉鏈帶4及鏈牙列3急劇收縮而於拉鏈鏈條中產生收縮斑，另外，可於拉鏈鏈條1的長度方向及寬度方向中使拉鏈帶4及鏈牙列3的熱收縮量難以產生偏差。In the chain cooling unit 50 of this embodiment, the zipper chain 1 is conveyed by a long conveyance distance of seven rounds, one side, and one side, and is slowly (slowly and finely) cooled by natural air under tension, Therefore, it is possible to suppress the rapid shrinkage of the fastener tape 4 and the element row 3 to generate shrinkage spots in the fastener chain, and to make it difficult for the heat shrinkage of the fastener tape 4 and the element row 3 in the longitudinal direction and width direction of the fastener chain 1 Deviation.

藉此，可維持利用前段的鏈條加熱部40延伸為筆直的拉鏈鏈條1的形態，並穩定地固定該筆直的形態。另外，亦可防止鏈牙列3的鏈牙間隔於左右的鏈牙列3間偏移。其後，利用鏈條冷卻部50冷卻至玻璃轉移溫度以下（尤其常溫）的拉鏈鏈條1自鏈條搬送部30排出而由鏈條回收部70回收。Thereby, the shape which extended by the front-stage chain heating part 40 to the straight fastener chain 1 can be maintained, and this straight shape can be stably fixed. In addition, it is possible to prevent the elements of the element row 3 from being shifted between the left and right element rows 3. Thereafter, the fastener chain 1 cooled to a glass transition temperature (particularly normal temperature) by the chain cooling section 50 is discharged from the chain transfer section 30 and recovered by the chain recovery section 70.

如上所述，藉由使用本實施例的矯正裝置10來對進行了超臨界流體的染色處理而成的、彎曲狀的產生有捲曲傾向的拉鏈鏈條1進行矯正處理，從而去除拉鏈鏈條1的捲曲傾向，並可穩定地獲得如圖2所示的具有筆直的形態的經染色的拉鏈鏈條1。As described above, the correction device 10 of this embodiment is used to correct the curly zipper chain 1 having a tendency to curl, which is subjected to the dyeing treatment of the supercritical fluid, thereby removing the curl of the zipper chain 1. It is possible to stably obtain a dyed zipper chain 1 having a straight shape as shown in FIG. 2.

尤其，本實施例中，於鏈條冷卻部50中，拉鏈鏈條1於長的搬送距離中一面被施加張力，一面緩慢地冷卻，因此拉鏈鏈條1的熱收縮量受到限制，可遍及整個帶長度方向將左右的鏈牙列3中的鏈牙間隔調整為固定大小。藉此，遍及整個拉鏈鏈條1使鏈牙列3的尺寸穩定，因此可提高拉鏈鏈條1的尺寸精度。In particular, in the present embodiment, in the chain cooling section 50, the zipper chain 1 is slowly cooled while being applied with tension during a long conveying distance. Therefore, the amount of heat shrinkage of the zipper chain 1 is limited and can extend throughout the length of the belt. The interval between the fastener elements in the left and right fastener element rows 3 is adjusted to a fixed size. Thereby, the size of the element row 3 is stabilized throughout the entire zipper chain 1, so that the dimensional accuracy of the zipper chain 1 can be improved.

再者，本實施例中，根據對拉鏈鏈條1施加的張力的大小而可改變（或調整）鏈牙列3的鏈牙間隔。例如，預先以各種條件進行拉鏈鏈條1的矯正處理，針對拉鏈鏈條1的搬送速度、利用張力調節輥61所施加的張力的大小、鏈條加熱部40的加熱溫度等各處理條件，預先彙集資料並加以累積，藉此可基於該所累積的資料來適當設定處理條件而進行矯正處理，藉此，可將拉鏈鏈條1中的鏈牙列3的鏈牙間隔容易且穩定地調整為規定的大小。Furthermore, in this embodiment, the element interval of the element row 3 can be changed (or adjusted) according to the amount of tension applied to the zipper chain 1. For example, the correction processing of the zipper chain 1 is performed in advance under various conditions.
