本申请披露了一种用于从贴标签机中的标签条(6)切割标签(5)的固定刀片组件(3、3’)，包括：支撑件(9)以及由所述支撑件(9)支撑的刀片(10)；刀片(8)包括适于切割所述标签(5)的至少两个切割刃(11a、11b、11c、11d)。

Description

固定刀片组件
技术领域
本发明涉及一种固定刀片组件。
背景技术
贴标签机是已知的，尤其是使用标签卷的类型，标签从该标签卷上切割并施加到物品(特别是填充有可流动食品的物品)上。
被称为辊供给式贴标签机的上述机器大致包括使物品沿着一路径前行的传送带、以及将多个标签施加到沿着该路径的相关物品上的贴标签单元。
详细地，该贴标签单元包括：
-至少一个机动供给辊，用于使来自标签卷的标签条朝向传送带移动；
-切割单元，用于从该标签条上切割给定长度的标签；以及
-真空抽吸滚筒，接收切割好的标签并将该标签转移至传送带中的物品。
切割单元包括定位成邻近真空抽吸滚筒的旋转刀片组件和固定刀片组件。
更准确地说，旋转刀片包括旋转滚筒和布置在旋转滚筒的外周处的一个或多个切割刃。
固定刀片组件包括支撑件和从该支撑件向外突出的刀片。
标签条在其自由端由真空滚筒抽吸，并且在切割单元的固定刀片与旋转刀片之间穿过。
更准确地说，由于真空滚筒以比标签条的速度更高的速度旋转，因而真空滚筒拉动标签条的端部。
标签条从而在由旋转刀片和固定刀片限定的通道中穿过。当旋转刀片和固定刀片面向彼此时，真空滚筒从标签条的其余部分切割并分离一标签。
固定刀片截面通常为五边形或三角形，并且仅包括一个切割刃。
此外，固定刀片通常由比旋转刀片更软的材料制成。
旋转刀片通常为具有多个可用边缘的方形。
此外，旋转刀片通常由较硬的材料(诸如硬质合金(carbide))制成，以抵抗由于标签滑过切割刃而导致的磨损。
因此，固定刀片需要比旋转刀片更换得更频繁。
工业上需要减少与固定刀片的更换相关的时间和成本，以增加贴标签机的生产能力(throughput)。
发明内容
本发明的一个目的是提供一种设计成满足上述要求的固定刀片组件。
根据本发明，提供一种用于从贴标签机中的标签条切割标签的固定刀片组件，包括：支撑件；以及由支撑件支撑的固定刀片；特别地，固定刀片包括适于切割标签的至少两个切割刃，固定刀片包括：锋锐地连接以形成一个相关的切割刃的至少一对第一表面；彼此相对的一对第二表面；以及彼此相对且横向于第二表面的一对第三表面；第一表面介于相关的第二表面与相关的第三表面之间。
附图说明
将参照附图以实例的方式描述本发明的优选但非限制性实施例，附图中：
图1示出了包括根据本发明第一实施例的固定刀片组件的切割单元的示意性顶视图；
图2为图1的切割单元的一些部件的放大图；以及
图3示出了根据本发明第二实施例的固定刀片组件的截面的放大图。
实施本发明的最佳模式
图1中的标号1整体表示用于从标签条6上切割标签5的切割单元。
切割单元1适于结合到贴标签机中，尤其是结合到用于将标签5施加至相关物品(特别是装满可流动产品的容器)的辊供给式贴标签机中。
详细地，该辊供给式贴标签机(未示出)大致包括：
-标签卷，标签条6从电动辊沿着路径A从该标签卷展开(unwind)；
-传送带，用于使物品沿着另外的弯曲路径前行；以及
-贴标签单元，用于将标签5施加到通过传送带前行的相关物品上。
贴标签机还包括至少一个供给辊，用于使标签条6从卷朝向传送带移动。
切割单元1从标签条6切割标签5并将它们朝向传送带传送。
切割单元1大致包括：
-滚筒2，围绕轴线B旋转；
-固定刀片组件3，适于与滚筒2相互作用以从标签条6分离标签5；以及
-真空抽吸滚筒4，适于使已从标签条6的其余部分分离的每个切割好的标签5前行。
详细地，滚筒2包括圆柱形主体7以及从主体7的外周12向外突出的刀片8。刀片8设置有切割刃39。
滚筒2还可包括多个刀片8。
组件3包括支撑件9以及从支撑件9向外突出的刀片10。
刀片10和主体7的外周12限定用于标签条6的通道15。
以在图1中示出的滚筒2的给定角位置，刀片8和刀片10的操作边缘紧邻地面向彼此或随着随后的切割动作而有极少的接触。
在这样的条件下，刀片8、10切割标签5并将其从标签条6分离。
真空抽吸滚筒4围绕与轴线B平行的轴线D旋转，并且通过施加到这样的切割好的标签5上的真空而将切割好的标签5朝向传送带传递。
刀片10有利地包括多个切割刃11a、11b、11c、11d，在所示实施例中为四个。
特别地，刀片10包括(图2)：
-彼此相对且平行的一对矩形夹持表面16；以及
-彼此相对且平行的一对矩形定位表面17。
刀片10在一个表面17至与其相邻的一个表面17之间还包括：
-横向于表面16的表面60；
-与表面60正交的表面50；
-与表面50正交的表面51；以及
-与表面51正交的表面61。
表面61、50；50、51；以及51、60彼此正交。
表面61、50、51、60通过使用砂轮来磨光。
彼此相邻的每一对表面50、51锋锐地连接，以形成相关的切割刃11a、11b、11c、11d。
彼此相邻的表面61、51；50、60彼此锋锐地连接。
表面60起始于相关表面16并从相关表面16开始彼此偏离。
表面61起始于相关表面17并从相关表面17开始彼此会聚。
表面16具有对称轴线C。
表面17具有与轴线C正交的对称轴线Y。
切割刃11a、11b、11c、11d相对于与轴线C、Y正交的轴线X略微倾斜。
切割刃11a、11b、11c、11d还相对于刀片8的切割刃39是倾斜的。
刀片组件3包括多个可释放的连接元件13，用于将表面16连接至支撑件9(图1)。
在所示实施例中，连接元件13由五到九个螺杆组成。
特别地，表面16限定由相关连接元件13接合的多个孔14。
连接元件13具有杆身(shank)，这些杆身成间隙地穿过相关的孔14。
孔14具有平行于轴线C的其自身的轴线。
支撑元件9包括主体20和从主体20突出的附件21(图1)。
主体20由壁29约束，所述壁与刀片10的一个表面16配合并且连接元件13拧到所述壁上。
附件21在主体20的相对的侧上从壁29突出。
刀片组件3还包括调节装置，以在接触调整之后使刀片10的最终位置稳定。
在所示的实施例中，调整装置包括：
-顶推螺杆(jacking screw)30，其穿过附件21并与刀片10的一个表面17配合；以及
-锁定螺母31，与螺杆30耦接。
从其中切割刃11c处于切割区域中的构造开始描述刀片组件3的操作。
标签条6从标签卷展开并且通过机动辊沿着路径A前行。
标签条6在其端部处由真空抽吸滚筒4抽吸，并且在通道15内前行，所述通道在其两侧上由切割刃11c和外周12限定。
由于滚筒2的围绕轴线B的旋转，在特定时间，刀片8面向组件3的刀片10的切割刃11c并且与这样的刀片8一起关闭通道15。
在图1中示出的这样的位置中，通过刀片8和刀片10的切割刃11c、39的动作从标签条6的其余部分切割一个标签5。
由于切割刃11c、39相对于彼此是倾斜的事实，因而切割动作是渐进的(progressive)。
切割好的标签5然后通过真空抽吸滚筒4的抽吸作用而朝向传送带传送，所述标签在该传送带处通过贴标组而施加到相关物品上。
在刃11c已经切割给定数量的标签5之后，刃11c变得磨损或钝化。在该阶段，连接元件13从支撑件9释放，刀片10旋转以使用刃11a来切割标签5。
参照图2，刀片10围绕轴线X转动180度，以便将刃11b布置在切割区域中的滚筒2的前方。
在该阶段，通过使用连接元件13，刀片10再次连接至支撑件9。
一旦刃11b也变得磨损或钝化，则刀片10通过支撑件9脱离连接，围绕轴线Y转动180度，以便将刃11d布置在切割区域中的滚筒2的前方。
在该阶段，通过使用连接元件13，刀片10再次连接至支撑件9。
最后，一旦刃11d也变得磨损或钝化，则刀片10围绕轴线X转动180度，以便将刃11a布置在切割区域中的滚筒2的前方。
图3中的标号3’表示根据本发明的刀片组件的第二实施例；刀片组3、3’彼此相似，以下的描述仅限于它们之间的差别，并且如果可能的话，对相同或对应的部件使用相同的标记。
刀片组件3’与刀片组件3的不同之处在于，支撑件9’包括多个圆角端臂40’。
臂40’在其靠近真空抽吸滚筒4和滚筒2的端部处具有接合刀片8的底座41’。
底座41’包括一对平坦壁42’，所述平坦壁面向彼此且位于与轴线C平行的平面上，并且靠近位于与轴线C正交的平面上的壁43’。
壁43’与刀片10’的表面16配合，并且壁42’分别与刀片10’的表面17配合。
连接元件13’部分地容纳在刀片10的孔14’内并且部分地容纳在由端臂40’限定的相关孔46’中。
与轴线C正交的壁43’的长度大于与轴线C平行的壁42’的长度。
刀片组件3’的操作与刀片组件3的操作类似并且不详细描述。
通过对根据本发明的固定刀片组件3、3’的特征的分析，本发明得以达成的优点是显而易见的。
特别地，刀片组件3、3’包括具有一个以上切割刃11a、11b、11c、11d的刀片10、10’。
通过简单地使刀片10、10’围绕轴线X或轴线Y转动180度，可容易地更换有效地切割标签5的切割刃。
因此，与在本说明书的前序部分中描述的解决方案相比，延长了刀片10、10’的寿命。
此外，降低了与刀片10的更换相关的时间损失和成本，从而提高了贴标签机的生产能力。
另外，由于刃11c、39相对于彼此是倾斜的事实，因而切割动作是渐进的。
最后，明显的是，可对固定刀片组件3、3’做出不背离权利要求的保护范围的修改和变型。
