Description

制造微波成型鞋的系统及其方法 【技术领域】
本发明涉及一种制造微波成型鞋的自动化系统。
【背景技术】
鞋子是人类的好朋友，史前时代的人类就知道穿鞋。最早的鞋子譬如以植物编织成草鞋、动物皮缝成的皮靴、木头作的木屐。有了纺织技术后逐渐发展出丝织布或麻布与动物皮结合，或以木材或金属作为鞋底的各种鞋靴。同时，文明的发展也使得鞋子用途不止于保护脚部更要求美观时尚甚至成为身份地位的表征。工业革命后，机械自动化加上塑橡胶材料的发明大幅地改变鞋类的材料与制造过程，逐渐使得鞋子从原本的纯手工转成得以大量地工业化生产。然而，即使鞋子已有漫长的发展历史，现今鞋子的制作技术能难以避免的繁杂的粘贴等劳工步骤和多次冗长的机器烘烤程序。因此有必要提供一种更有效率的制鞋技术。
【发明内容】

【具体实施方式】
为使本发明及其所要主张的申请专利范围能被充分地理解，以下将示范本发明的优选实施例。为避免模糊本发明的内容，以下说明可能会省略已知的元件、相关材料、及其相关处理技术。
以下将参考所附图式示范本发明制造微波成型鞋的的优选方法，其包含步骤(a)提供一模具，该模具有一鞋型空间；步骤(b)将一鞋楦置于该鞋型空间，该鞋楦为一鞋面所包覆；步骤(c)提供一鞋底基材于该鞋型空间，该鞋底基材包含发泡粒子，该发泡粒子可为热塑性聚氨基甲酸酯；及步骤(d)微波照射该鞋底基材，以使该鞋底基材结合该鞋面。
首先说明步骤(a)：提供一模具，该模具有一鞋型空间。模具可参考中国台湾专利M565121的可透微波的模具结构(如图1)或其他合适的模具。参考图1，模具100具有一上模板110及一下模板120。上模板110及下模板120组合后内部可构成一鞋型空间130。模具100的特点在于具有锁合结构可防止模具100因膨胀导致上模板110及下模板120松脱。详言之，参考图1，锁合结构具有第一卡设件31、第二卡设件32及结合件33，第一卡设件31设置于上模板110，第二卡设件32设置于下模板120，结合件33结合于第一卡设件31与第二卡设件32之间，使上模板110及下模板120于承受外张的压力时，能透过结合件33的对应面抵于第一卡设件31及第二卡设件32的卡抵面，进而使上模板110及下模板120不会因为模具100内部压力增加而分离。当上模板110及下模板120密合时，必须施加适当地压力于模具100上，如此结合件33才得以置放在第一卡设件31与第二卡设件32之间进而将模具100的上模板110及下模板120锁合。如要解锁， 同样地必须施加适当地压力于模具100上，如此结合件33才能从第一卡设件31与第二卡设件32之间移开，进而解锁。模具100主要由塑胶材料或陶瓷所制成，如聚丙烯、聚氯乙烯、聚对苯二甲酸二甲酯、聚四氟乙烯、石英、液态硅酮橡胶同、环氧树脂等。模具100可含少量的金属，其作为锁合部件用以加强密合性，金属以铁为较佳。模具100的金属含量不超过模具100的总体积的10体积百分率，或更佳而言，金属含量范围为模具100的总体积的2至6体积百分率。
参考图2，显示一已包覆鞋面220的鞋楦210。鞋面220可有各种变化，可为各种鞋的面，如拖鞋、凉鞋、皮鞋、运动鞋等。参考图3，显示步骤(b)的进行是将鞋楦210连同鞋面220置于鞋型空间130中。
以下说明步骤(c)：提供一鞋底基材于鞋型空间130，鞋底基材包含发泡粒子，例如热塑性聚氨基甲酸酯。此步骤所使用的发泡粒子主要作为鞋底。除发泡粒子外，鞋底基材可视需要包含鞋边条、鞋大底、其它功能性组件等、及/或各组件间粘着层或与鞋面的界面间的粘着层。发泡粒子可以是分散的，也可以是已经过一次微波而互相连结的多个发泡粒子。此外，发泡粒子为热塑性聚氨基甲酸酯时也具有粘着功能。由于热塑性聚氨基甲酸酯照射微波时会产生粘性，因此欲与发泡粒子接触相连的鞋面或各组件/元件并非一定需要额外粘着层，其可视实际材料的施作状况调整。图4A及图4B显示步骤(c)的实施例，直接分配多个发泡粒子400于该鞋面220上。多个发泡粒子400的总数目应多到足以形成强度足够的鞋底，图4A只显示的实际所用总粒子数的一部分。可视需要置入鞋大底410或其他功能性组件于鞋型空间130中，如图4B。完成步骤(c)后，将上模板110及下模 板120密合或更佳地锁合，然后将模具100送入微波室进行步骤(d)：以微波照射发泡粒子，使鞋底基材与鞋面220结合。步骤(d)完成后，即可获得本发明所述的微波成型鞋。
图5显示本发明将上述方法改良的系统70用以至少部分自动化地制造微波成型鞋。本发明的制造微波成型鞋的系统70包含：至少一模具，该模具包含一鞋型空间；一鞋楦，用以置于该鞋型空间中，该鞋楦为一鞋面所包覆；一鞋底基材，用以置于该鞋型空间，该鞋底基材包含多个发泡粒子。系统70中有关模具、鞋型空间、鞋楦、鞋面、鞋底基材、多个发泡粒子可参考前述。如图5所示，系统70更包含一装卸单元71，该装卸单元将该鞋楦及该鞋底基材装入该模具或取出一微波成型鞋；一锁合单元73，锁合模具；一微波单元74，微波鞋底基材以形成结合该鞋面锁合单元73的一鞋底；一解锁单元75，解锁该模具；以及一传送带72，用以在上述四个单元的任意两个之间传送该模具。于一优选实施例，传送带72可实质地穿过每个单元。
装卸单元71主要执行上述的步骤(b)(将一鞋楦置于该鞋型空间，该鞋楦为一鞋面所包覆)以及步骤(c)(形成一鞋底基材于该鞋型空间，该鞋底基材包含发泡粒子)的工作。装卸单元71也包含清模工作。以上述的模具100为例(但不以此为限)，清模工作例如打开模具100(将上模板110及下模板120分离)取出微波成型鞋，或对模具100作清洁保养等等。上述工作可藉由人工或机械来执行。于装卸单元71完成步骤(b)及(c)后，可进一步将模具100的上模板110及下模板120密合但尚未锁合。密合后的模具100接着经由传送带72移动到锁合单元73。于一实施例，传送带72更包含可移 动式平台721(显示于图6)，用以放置模具100。可移动式平台721会随着模具100一起被传送带72带动。每个可移动式平台721对应一个模具100。
如图6所示，锁合单元73主要包含加压装置600，设置于传送带72的一预定位置。当模具100到达该预定位置时，加压装置600施加适当地压力于模具100上以使结合件33得以置入模具100中将其锁合。锁合后的模具100接着经由传送带72移动到微波单元74。
微波单元74主要执行上述的步骤(d)(微波照射鞋底基材，以使鞋底基材结合鞋面)。参考图7，微波单元74主要包含微波装置731、控制面板732、隧道腔体733、及设置在隧道腔体733两端的闸门734、温度感测器(未显示)、辐射感测器(未显示)、散热装置(未显示)等等。闸门734可在微波装置731作用期间关闭隧道腔体733以防止微波外泄。使用者可经由控制面板732调整微波装置731的微波频率、微波时间或其他各种功能。微波单元74可具有监视器736用以观察隧道腔体733内的状况。另外，也可于微波单元74设置管控系统70整体的控制处理器737，如此使用者可通过连结控制处理器737的控制面板732以管控系统70整体。
微波单元74可一次微波一个以上(含一个)的模具100。于优选实施例，微波单元74的隧道腔体733设计成足以使n个模具100于隧道腔体733同时微波，n为不大于10的正整数。于更佳的实施例，n大于1而小于7。系统70能运作的模具100的总数目不大于4n。在多个模具100同时微波的状况，此等模具100可在微波单元74的闸门734外排队等候，直到所有待微波模具100均到齐后，藉由传送带72将成串地待微波模具100送进微波单元74的隧道腔体733，接着关上闸门734进行微波。
完成微波后，经由传送带72将模具100从微波单元74移动到解锁单元75。从微波单元74移动到解锁单元75的期间可称为塑型期。于优选实施例，系统70的控制处理器被配置成使每个模具100从微波单元74移动到解锁单元75的期间不超过10分钟的范围。
解锁单元75与锁合单元73相似，可参考图8，解锁单元75主要包含加压装置800，设置于传送带72的一预定位置。当模具100到达该预定位置时，加压装置800施加适当的压力于模具100上，以使结合件33(图未示)得以从模具中移除。解锁后的模具100接着经由传送带72移动到装卸单元71。
于一实施例，模具100的锁合是在装卸单元71中将模具100密合时一并完成。举例而言，当模具100停留在装卸单元71的预设位置时，在移动式平台721上的模具100可以全面人工或部分地由机械辅助方式进行开模、清模、装填材料及锁模，在此实施例没有实质上被传送带72分隔的装卸单元71与锁合单元73，即传送带72并没有将模具100从装卸单元71送到锁合单元73而是直接送到微波单元74。相较此实施例，装卸单元71与锁合单元73实质上被传送带72分隔的实施例其实际产出的良率较佳。
于另一实施例，模具100的解锁是在装卸单元71中进行清模前完成。在此实施例没有实质上被传送带72分隔的装卸单元71与解锁单元75，即传送带72直接将模具100从微波单元74直送到装卸单元71。相较于此实施例，装卸单元71与解锁单元75实质上被传送带72分隔的实施例其实际产出的良率较佳。同一单元的工作复杂度的降低，可减少发生错误机会。于优选实施例，此系统100是通过控制处理器737配置成使模具100 于20分钟之内自微波单元74再回到微波单元74。
应注意以上仅示范优选微波成型鞋，本发明仍包含于其他各种微波成型体。而且上述的微波成型鞋是用于说明本发明并非用以限定本发明。凡其它未脱离本发明所揭示的精神下所完成的等效改变或修饰，均应包含在下述的申请专利范围内。
