Description

用于定位工件的方法和装置
背景
本发明大体涉及工件的定位，更具体地说，涉及用于使被输送通过辊带式输送带上的作业区域的工件的所有侧部呈现给工具的输送机和方法。
肉制品经常以盒装的形式被传送到肉切割设备。盒内的物品是处于密封袋中的多个肉切块。典型地，盒经常被手动地切开，且肉袋被放置在输送机上以由其他操作员打开。手动切割耗费人力，并且存在安全风险。
X射线和其他检查工具或感应工具被用于鉴定物品或针对可疑容纳物而检查物品。如果从不同视角检查物品，则检查更加费力。
概述
一方面，实施本发明特征的工件定位装置包括可在第一方向上或在与第一方向相反的方向上推进的输送带。输送带具有工件支撑辊，工件支撑辊可在被定向为与第一方向倾斜的轴线上旋转。输送带辊在具有四个侧部的作业区域内支撑工件。沿作业区域的每个侧部而设置的引导面对齐并引导工件。工具设置在沿作业区域的每个侧部的中间位置处，以与沿着侧部而抵靠引导面对齐的工件的侧面相互作用。输送带被选择性地在第一方向和在与第一方向相反的方向上推进，且辊与输送带的推进相配合地被选择性地致动和退动(deactuated)。此配合使得工件沿着引导面没有旋转地平移通过作业区域并沿着作业区域的每个侧部经过工具，使得工件的每个侧面呈现给工具。
在本发明的另一方面，用于定位工件的方法包括：(a)在双向输送带的倾斜地可旋转的辊的顶部上在沿着矩形作业区域的侧部的矩形路径上没有旋转地平移工件；以及(b)沿着作业区域的每个侧部将工件的不同侧面呈现给工具。

详述
图1示出采用实施本发明特征的工件定位输送机11的盒切割系统10。操作人员12从剪刀式提升器16上的托盘层卸下工件，在此示例中，工件是盒14，并将工件放置在进料输送机18上。操作员按下按钮(未示出)，以将盒引入盒切割器20中。在盒的所有四个侧面或板P均被切割之后，盒的底部24和封装的容纳物26与盒的顶部28一起从盒切割器而卸载到卸料输送机30例如倾斜的输送机或斜道上。在盒被切割的同时，操作员将未切割的盒放在进料输送机上。然后操作员在卸料输送机30上或在取走输送机32上将所切割的盒的顶部和底部与盒的容纳物分离。操作员将盒的顶部和底部堆积在除杂输送机34上以用于处理。取走输送机32将容纳物26运送到下游处理站。进料输送机与卸料输送机、取走输送机和除杂输送机紧密地邻近，这允许操作员有效地执行这些步骤。
图1-3显示了盒切割器20的细节。如图2A-2C所示，盒切割器包括工件定位系统11，工件定位系统11具有能够在向前方向38或相反方向39上推进的输送带36。输送带被常规地布置成在上部路程(upper run)的每一端处围绕滑轮或链轮(未示出)。在此示例中，输送带通过使轴41驱动的马达40而被双向地驱动，其中在返回路程(return run)中间接合带的驱动链轮安装在轴41上。如图3A-3F所示，输送带具有延伸穿过带的厚度的多个辊40，以支撑盒的底部。辊在形状上通常是圆柱形且安装在形成旋转轴线44的轴杆上，旋转轴线44倾斜于带运行的方向38、39。美国路易斯安那州Harahan的Intralox L.L.C制造并出售的一种倾斜辊模块化塑料带，
Figure BDA0000131941350000031
系列400型活动辊TM带(400 activated rollerTM belt)，适合于此应用。
如图2A-2C所示，输送带36的上部路程在盒切割器20中限定矩形作业区域46。因为上部路程的长度等于输送带的宽度，所以矩形作业区域大体与等长度的四个侧部48、49、50、51相符。如图1所示，盒切割器包括切割头52，其中四个切割工具例如圆形锯54安装到切割头52的侧壁56。锯沿着切割头的每个侧壁而安装在相对连接的侧壁之间的中间位置比如中点处。切割头可由例如位于盒切割器拐角处的伸缩腿57中的提升器而升高以允许盒进入和退出盒切割器，且切割头被降低以定位切割工具从而在盒上操作。切割头52的四个侧壁56的内侧包括引导面58，引导面58使盒对齐并引导盒沿着作业区域的每个侧部而经过切割工具。切割头还在作业区域上方形成安全盖并防止锯尘从切割器逃逸。
如图3A-3F所示，当带在任一方向上推进时，倾斜带辊42通过将支撑表面62选择性地升高和降低(如箭头60所示)成与突出穿过带底部的辊接触和脱离接触而被致动和退动。支撑表面可以以非升高和降低的方式而运动成与辊接触和脱离接触。例如，在带运行方向上延伸并且以与带辊的纵向列相同的距离侧向地间隔开的一系列的平行支撑表面可通过侧向平移而运动成接触和脱离接触。另外，支撑表面可形成在辊的外周上而不是在平盘或带状物上。如图3C和3E所示，当支撑表面接触辊时，带的运动引起辊在辊斜轴线44上旋转，具有在带的运行方向上在受支撑的盒下方的一个运动分量和垂直朝向带的侧部的另一分量。所以，随着支撑表面接触辊，辊被致动。当支撑表面降低或者以其他方式运动成脱离与带辊接触时，辊在其轴线上不旋转，其被退动。当辊退动时，仅当被支撑在辊的顶部上的盒遇到障碍物比如阻碍其在带的运行方向上推进的引导面时，辊才在其斜轴线上旋转，如图3B、3D和3F所示。在这些情形下，倾斜辊旋转而具有与带的运行方向相反的运动分量和与阻碍的引导面平行的正交分量，这使盒抵着引导面而滑动同时将盒推靠在引导面上。通常，当带辊通过某些东西而被活动地旋转例如在支撑面上滚动、而不是与在带运行方向上的推进受到阻碍的盒相互作用时，带辊被认为是“被致动的”。
如图4所示，盒切割器由控制器64控制。控制器可被实现为可编程序逻辑控制器、台式计算机、工作站、内置微控制器或任何合适的可编程设备。控制器协调带的运行方向和带辊的致动，以使盒围绕作业区域而移动经过每个切割工具。控制器具有三个主输出信号：例如通过线性致动器69来升高和降低支撑表面的致动/退动信号66，控制输送带马达40的方向的向前/反向信号67，以及对于升高和降低切割头的提升马达70的上/下信号。其他输出信号(未示出)包括用以驱动进料输送机驱动装置以及可能的卸料输送机驱动装置74、取走输送机驱动装置75和除杂输送机驱动装置76(如图1)的信号以及用以打开和关闭切割工具的信号。控制器还接收来自传感器80比如压力开关或光学设备的输入信号78，当盒与沿着作业区域的侧部的其中一个引导面接触时，传感器80进行感应。
参照图2、3和5描述了用盒切割器来切割盒的操作顺序。如图2A所示，操作员12将盒14放置在与盒切割器20的矩形作业区域46相符的进料输送机18上。同时，如由图5的时序图表所示，切割工具处于升高的位置(UP)以允许盒进入作业区域。输送带以向前的方向(FWD)38推进，并且带辊42是退动的。为了图示性的目的，作业区域的四个侧部由图中圆圈中的数字1-4表示。图5中的从带圆圈的数字向下延伸的每个竖直虚线表示盒与由相关的圆圈中的数字指示的侧部初始接触或初始交叉的时间。盒循着大体矩形的路径而通过作业区域。路径区段在图2中以A-F来标识且大体对应于图3A-3F和图5中的时间间隔A-F。
盒通过进料输送机而被引到切割器作业区域的侧部3上。一旦盒经过侧部3，控制器便通过将上/下信号的状态改变至下信号的状态(图5中的82)而降低切割头。因为输送带向前运动且辊是退动的，所以盒循着线性路径区段A到达作业区域的侧部1。如图3A所示，支撑表面62被降低且辊不旋转。只要盒的向前侧板P1碰撞到作业区域的侧部1处的引导面48，盒的向前推进就被阻止，这引起退动的辊如图3B所示地旋转，并通过侧部1上的引导面的引导而沿着图2A中的路径区段B将盒推动至右侧。
一旦右侧板P2碰撞到作业区域的侧部2处的引导面，来自用于侧部2的传感器的信号便会通知控制器以使输送带反转并使带辊致动(图5中的83)。位于作业区域中的输送带下方的支撑表面62被升高至与辊的底部接触，这使辊在与路径区段B相同的方向上保持滚动，而且还沿着侧部2上的引导面而推动盒经过旋转的圆形锯片并朝向侧部3。锯片沿着侧板P2切割出水平狭缝。
当盒的向后侧板P3(现在是向前地)碰撞到作业区域的侧部3处的引导面时，来自用于侧部3的传感器的信号通知接触的控制器。控制器使辊退动(图5中的84)，这引起在反向运行的输送带上的盒抵着侧部3处的引导面沿着线性路径区段D而侧向地滑动到图2中的左侧。当盒滑过时，侧部3上的切割工具在盒的侧板P3中切割出水平狭缝。
当盒的左侧板P4碰撞到作业区域的侧部4处的导轨时，用于侧部4的传感器发信号给控制器，以使输送带反转回到向前的方向并使带辊退动(图5中的85)。这引起退动的辊如图3E所示地旋转，并在盒沿着路径区段E被输送时将盒推靠在作业区域的侧部4处的引导面上。当盒经过时，沿侧部4的锯在盒的侧板P4中切割出水平狭缝。
当盒的向前侧板P1到达作业区域的侧部1时，来自用于作业区域的侧部1的传感器的信号通知控制器，控制器然后使辊退动(图5中的86)。因为盒被侧部1处的引导面阻挡，所以退动的辊反转其方向并使盒在路径区段F上沿着侧部1的导轨滑动。就在侧部1上的切割工具在盒的向前板P1中切割出水平狭缝之后，控制器发信号给提升器以升高(图5中的87，上)，以使盒可在作业区域的侧部2上被卸料至卸料输送机30上。此循环重复以用于下一个进入的盒。
因而，盒切割器的工件定位带输送机将盒在大体矩形的路径中平移而不旋转，盒被按顺序地推靠在四个侧部上的限制作业区域的引导面上并经过每个侧部上的切割工具。每个切割工具在盒的一个侧板中切割出水平狭缝。狭缝是对齐的，使得围绕盒的周围形成连续的切口以允许容易地去除其容纳物并容易处理盒的切段。
如图6所示，工件定位带输送机11可与沿作业区域46的每个侧部被定位的其他工具90一起使用，其他工具90例如条形码或其他光学阅读机、RFID标签阅读机、X射线扫描器或其他检查工具90。所示检查工具被安装到与图1的盒切割器的切割头类似的盖子92的四个侧部。(图6中所示的盖子处于升高的位置)因为当盖子被降低时，工件的每个侧面94均呈现给一个工具，所以工具与其面对的侧面相互作用。在检查工具的情形下，呈现给检查工具的工件侧面可被直接检查，或者工件的容纳物可被通过侧面进行检查。工件定位输送机在使工件的每个侧面呈现给以某种方式与所呈现的侧面相互作用的工具上是有效的。
虽然本发明已被参照特定型式而详细地描述，但其他的型式也是可能的。例如，所示的输送带具有延伸穿过带的底部以接合支撑表面的辊。但也可以在盒切割器中使用不是必须延伸至带的底部下且可以其他方式被致动的辊，例如电动辊或磁性致动辊。作为另一个例子，控制器可被编程以在不同路径上将工件输送通过作业区域。可以使用被设置为在盒的侧部中切割出不同形状的切口的不同种类的检查工具或传感器或切割工具。因此，如这几个示例所建议的，权利要求不意味着限制于本公开内容的细节。
