参照相关申请
1、根据35U.SC.§119(e)，本申请要求申请日为2003年6月20日、临时美国申请US60/797,909的优先权，其全部内容在此引入作为参考。
技术领域
本发明通常涉及注射成型系统控制器，尤其是模具和热流道控制器。
背景技术
注射成型系统用于形成一些塑料或树脂和诸如金属和粉末型等其它材料的物体。通常，注射成型系统包括具有挤压机的注模机，可通过连杆连接的机器压板和机座。机器压板用于固定模板，模板包括模腔和模芯。每一模具通常具有两部分，冷半模和热半模。在注射成型工艺中，冷半模和热半模紧密配合形成适合的形状。热半模包括热流道系统，热流道系统包括歧管和一个或多个热流道喷嘴，热流道喷嘴包括流道，熔体流穿过该流道，经过一个或多个模具口到达模腔。为了最佳成型，熔体流必须保持在诸如温度和压力等操作工艺参数相当小的范围内。为此，模具的冷半模和热半模通常包括用于监控这种熔融物物理性质的传感器。例如，热半模通常包括安装在适当位置的热电偶，以监控不同位置例如沿着熔融物流道的温度。
注射成型系统通常包括至少一个机器控制器，用于在注模机内和有时在模具内监控和调节诸如温度和压力等临界工艺条件。有时，除机器控制器外，有分开热流道或和模具控制器的需要。热流道控制器通常配置在车间内注模机旁的地板上，且通过连接模具和控制器的电缆接收来自传感器的信息。为了在工艺过程中在注射成型系统内更好地控制熔融物的特性，在标准注射成型系统内有许多需要分别监控和调节的区域，使得在每个模腔内都能最佳成型。因此，标准注射成型系统的每个区域都有自己的自动调节闭环控制。
为了在模具内部监控和调节工艺条件，注射成型系统使用以微处理机为基础的控制器。控制器通常响应被配置在模具热半模内适当位置的传感器的输出，通过给注射成型系统内部的装置传送控制信号，该注射成型系统能够按控制信号改变工艺条件。例如，如果模具内的传感器报告模具某一区域处于较低的温度，控制器将响应，通过传送控制信号给加热装置，则能够提高该区的温度到适当的标准。
在标准注射成型控制系统中，当报告模具的工艺条件时，模具传感器提供信号给控制器。从每一个传感器得来的这些信号通过导线传送给控制器，和在有模腔32，64，或96的注射成型系统内，可能需要成百根导线。在标准注射成型系统中，由于其特大的尺寸，控制器与模具之间有一定距离。承载从注模到控制器的导线所需电缆的数量和尺寸是庞大的，因为电缆需要沿着地板，在地板下，或在地板上延伸，存在存储和机器通道问题和不方便性等问题。
除了特大尺寸之外，为了保护控制器远离正常注射成型工艺中产生的高温，标准注射成型系统的控制器同样与模具之间有一定距离。如果控制模块就安装在注模上，注射成型工艺产生的热量有可能对控制器内部电子设备的性能和可操作性有负面的影响。安装在模具上的公知的控制器需要冷却机构来阻止这种负面影响。同样这些控制器对特定的模具和热流道系统完全是专用和定做的，所以它们能够随着模具和热流道系统从一个机器移到另一个机器。用来注射新产品的新模具和新热流道系统在大多数情况下将需要重新定做的控制器。进一步地，在标准注射成型系统中，控制器和定做的热流道系统必须兼容和有兼容连接器。
发明内容
本发明一方面提供一种注模机，包括：安装在机器压板上的注模，所述注模具有热半模和冷半模；至少一可控装置，为了改变注模的工艺条件与注模连接；至少一与注模连接的传感器，报告工艺条件的值；和一控制模块，安装在机器压板上，所述控制模块与所述至少一传感器和所述至少一可控装置相连，所述控制模块收集所述至少一传感器的输出，处理所述传感器输出，和提供控制信号给所述至少一可控装置。
附图说明

通过详细描述本发明的特点和优点将更明显，该详细描述结合附图阐明下面的内容，在附图中相同的附图标记自始至终标识相应的部件。在附图中，相同的附图标记通常表示相同的，功能相似和/或结构相似的部件。
具体实施方式
参照图1和2A，概括显示注模机100。该注模机包括安装在机座102上的固定机器压板104和注模。所述注模包括热半模106和冷半模234，热半模106与机器压板104可拆装地连接，其在图2B中示出。冷半模234可沿机器连杆108滑动与热半模106配合。如图2A中所示，热半模106包括至少一与歧管111连接的热流道喷嘴107。歧管111接收来自源点(未示出)的可模压材料的熔体流并将上述熔体流经喷嘴107输送到模腔113。模腔113设在热半模106和冷半模234之间。
喷嘴107通过加热器109A被加热。为了在其中提供温度测量，把热电偶110A与喷嘴107连接。本领域技术人员可以理解的是，热半模中同样也可以使用诸如例如压力传感器的其它的传感器110以监控工艺条件。
控制模块216通过机板连接器218安装在固定机器压板104上。除了将控制模块216安装在固定机器压板104的外部之外，控制模块216也可以可选择地安装在固定机器压板104的内部。至少一电缆222将机板连接器218和模板连接器220连接起来。电缆222包括至少一向控制模块216输送信号的导线、和至少一从控制模块216输出信号的导线。特别地，在一实施例中，每一监控区域使用两根导线，一根导线向控制模块216输送传感器输出信号，一根导线从控制模块216向诸如加热器的可控装置109输送动力信号。信号输送可通过应用光纤技术或本领域技术人员公知的其它技术完成。
模板连接器220连接注模的热半模106，尤其连在传感器110上，例如热半模106中的热电偶110A。连接器218，220和电缆222可以封装在固定机器压板104的内部，或可以在其外部。机器压板104上的控制模块216的配置是这样的：不需要在工作区内敷设电缆，在注射成型工艺过程中所产生的热量对控制模块216的操作没有负面影响。
机板连接器218通常是一个电接线盒，通过它电缆222的一端与控制模块216连接。在一实施例中，如图3中所示，控制模块216和机板连接器218之间的连接是通过插塞接头360。这种插座的应用使控制模块216的拆卸和更换迅速高效。本领域技术人员显然也可以使用其它类型的连接器。
返回参照图1，为了与不同厂家生产的不同类型的注模相适合，对于不同的电缆222和模板连接器220，电缆222和模板连接器220可以更换。这就允许不同厂家生产的注模使用相同的控制模块216，而不依赖模具厂家。这就使得控制模块更通用，且使注模机的转换更有效和更少时间消耗。控制模块216和机板连接器218应用和替换的灵活性使控制模块216可被迅速地和便利地移到另一个机器。进一步地，可以去除控制模块216，且当其没有安装在机器上时被用来检测注模。
控制模块216从电源228获得3相220伏交流电，电源228或位于注模机100上，或位于地板上与注模机100分开。电源228的电力通过电力电缆230输送到控制模块216。
控制模块216起监控和响应传感器110提供的信号的作用。例如，在一实施例中，该实施例中传感器110是用于感测温度的热电偶，传感器110通过电缆222内的导线将温度数据的输出信号输送给控制模块216。控制模块216接收传感器的输出信号并进行处理。如果温度需要升高，控制模块216通过电缆222内的导线传送控制信号给可控装置109在本场合中可控装置是加热器，以提供更多的电力。如果温度需要降低，控制模块216通过电缆222内的导线传送控制信号给可控装置109以使其提供较少的电力。
参照图2B，注模机100被更详细地显示。如图所示，机器注射单元232与固定机器压板104相通，以向其输送热熔流。进一步地，冷半模234安装在可动机器压板236上。在操作中，可动机器压板236通过行程汽缸242可沿连杆108移动，使热半模106与冷半模234配合形成完整的注模。夹紧缸244包括安装在固定夹紧板238上的夹紧柱塞240。夹紧柱塞240推动可动机器压板236和冷半模234向固定热半模106靠拢，一旦冷半模234和热半模106配合，夹紧柱塞240维持冷半模234和热半模106对接，以防止在注射工艺过程中冷半模234和热半模106分离。
参照图2C，示出可能如上所述监控的不同的传感器110A、110B、110C。这些传感器包括，但不限于此，温度传感器110A、压力传感器110B和阀销位置传感器110C。可控装置109包括加热器109A和阀销109C。
图2A中所示的电缆222更详细地显示在一实施例中用于两个区域。标准注模机包括更多的区，但为了简明在此描述两个。每一个区域包括被连接到模板连接器220上的模具电缆250A，250B、常规模具连接器252A，252B和热流道连接器254A，254B。热流道连接器254A，254B的适配器256和机器电缆258将热流道连接器254A，254B和机板连接器218连接起来，然后机板连接器218连接控制模块216。适配器256允许控制模块与不同厂家生产的注模相连接。
根据图1中所示的注模机100的实施例，显示界面模组(DIM)226被提供。DIM 226有三个主要作用。参照图4的框图，DIM 226的一个作用是从控制模块216接收已处理的传感器输出数据信号480，在存储器488内存储数据480，存储器488位于DIM控制单元484中，和在屏幕486上为用户显示数据480。DIM 226的第二个作用是收到用户输入的给定值数据例如温度给定值数据或压力给定值数据，例如，在位于DIM控制单元484内的存储器488内存储用户输入的给定值数据，和向控制模块216提供用户输入的给定值数据482。包括DIM 226和控制模块216之间的信号480，482的通讯，穿过诸如串联通信接口的通信接口发生。通过处理数据电缆内的导线，通过无线装置或通过其它本领域技术人员公知的或通常使用的通信装置可以传送这些信息。例如，DIM 226和控制模块216之间的通讯可以通过图1中所示的控制模块216中的收发器217和DIM 226中的收发器227完成。DIM 226和控制模块216输出和输入通信的信息载体被概括地描述如224。DIM 226的第三个主要作用是为控制模块216的电源开关。
DIM 226内的存储器488既能够存储从传感器110收集到的历史信息，也能够存储由用户输入的、代表热半模106内的工艺条件期望值的给定值数据。DIM226同样可以包括存储器，例如存储器488，用于存储从摄像机收集的数字或视频数据，所述摄像机为了进行监控可以安装在注射成型系统的内部。DIM 226是易于移动的且能够与其它注模机交换。例如，DIM 226能够远离注射成型系统，能够被牢固装配在注射成型系统上，或能够安装在注模机上任一适宜的位置，例如应用磁铁或能够摆动的臂(未示出)。DIM 226的可移动性，连同它的存储特性，允许在生产装配中将准备好的用户输入给定值数据立即应用在其它注射成型系统中。
图5描述注模机100的控制系统的操作方法且通过附图标记500大概地示出。如步骤504中所示，通过注模内的传感器报告注模的工艺条件。在步骤506中，如上所述的控制模块收集传感器的输出。在步骤508中，控制模块处理传感器输出。在步骤510中，可在控制模块和DIM之间进行交换通信。步骤510中的通讯在图6中被进一步描述。在步骤512中，通过控制模块响应传感器输出或响应用户输入的给定值数据产生控制信号。在步骤514中，将控制信号输送到可控装置，可控装置能够根据控制信号改变工艺条件。在步骤516中，所述方法重复步骤502。控制信号不必只由热半模106内的可控装置109应用。在本发明的另一实施例中，也将控制信号传送给分开的机器控制器(未示出)，同样通过机器应用来调节参数。机器控制器是注射成型系统机器的主要控制器。
参照附图，方法500的步骤510被更详细地显示。步骤510在步骤602开始，且立即向步骤604移动。在步骤604中，控制模块向DIM提供已处理的传感器输出。在步骤606中，在DIM的存储器中存储已处理的传感器输出。在步骤608中，在DIM上将已处理的传感器输出显示给用户。在步骤610中，DIM能够接收与可控装置有关的用户输入的给定值数据。在步骤612中，将用户输入的给定值数据存储在DIM的存储器内。在步骤614中，DIM向控制模块提供用户输入给定值数据。在步骤616中，该方法转移到图5的步骤512。根据本发明的另一实施例，处理传感器(未示出)配置在冷半模234上用来监控不同的工艺条件，例如模具核心冷却剂的温度，加热器或模腔的压力。配置在冷半模234的传感器110和控制模块216之间的线路包括按入式连接器或其它电接点，在模具打开期间物理地断开。
虽然本发明的特殊实施例已在上面描述，可以理解的是，它们只是作为例子提出，而不是对本发明的限制。本领域技术人员可以理解，虽然在其形式和细节上可以产生各种各样的变化，但没有离开本发明附加的权利要求所限定的精神和范围。因而，本发明的范围及其延伸不限于任一上述示范的实施例，只不过依照下面的权利要求及其等效加以限定。
