Description

用于卷起材料幅面的卷绕装置
技术领域
本发明涉及一种用于将沿着运行方向运行的材料幅面卷起的卷绕装置，所述卷绕装置具有至少一把用于将材料幅面沿着幅面方向分割成多个子材料幅面的刀并且具有用于将所述子材料幅面的棱边翻折的翻折装置。
背景技术
拉伸膜用于对各个物品、比如堆放在货板上的袋进行烧结和包装。所述物品在此用拉伸膜来包缠，使得所述物品借助于自附着的伸拉膜来彼此连接。已经证实的是，伸拉膜的边缘经常是在包缠和包装的期间引起断膜的起点。在伸拉膜卷的边缘或者棱边处的损坏可能使所述伸拉膜卷不能用。如果伸拉膜的卷绕完毕的卷违反操作规程地被运送或者落到地上，那比如就会产生这样的损坏。
已知的是，在卷到卷筒上之前通过对于边缘的翻折或者折叠所述伸拉膜相对于损坏变得更具抵抗力并且后来出现的撕断较少。不过，对于边缘的翻折也会导致以下情况，即：在棱边笔直地缠卷薄膜卷时会产生棱边堆积，所述棱边堆积同样让薄膜卷变得不能用。因此，在翻折棱边时，需要将薄膜的边缘彼此错开地卷在卷筒上。这比如能够通过卷轴的侧向振荡来进行。
由US 8,221,298 B2已知一种用于制造塑料膜的未翻折的棱边的装置，其中在每把刀的后面设置了翻折元件并且其中每个翻折元件产生两条被翻折的棱边。
由WO 2015/055726 A1已知一种用于卷起连续的材料幅面的卷绕装置，所述卷绕装置具有至少一把用于将材料幅面沿着幅面方向分割成多个子材料幅面的刀并且具有用于将子材料幅面的棱边翻折的折叠装置。所述卷绕装置包括振荡装置，用所述振荡装置能够使所述至少一把刀横向于幅面方向运动。
由EP 2 952 459 B1已知用于制造一定数量的被卷起的薄膜卷的一种装置和一种方法，其中所述薄膜在其边缘区域中通过翻折而得到增强。两个并排布置的薄膜区段的侧面的端部区段在此借助于两个相邻的翻折元件来翻折。
对于已知的卷绕装置来说，折叠单元直接布置在刀的后面并且机械地与所述刀耦合。为了对棱边进行折叠而使用折叠单元，所述折叠单元将相邻的薄膜幅面的两条对置的棱边一起翻折。在此已观察到，在所述薄膜上可能产生折皱，所述折皱本身可能对薄膜的功能产生影响。
发明内容
以此为出发点，本发明的任务是，提供一种卷绕装置，所述卷绕装置能够尽可能无折皱地卷起具有被翻折的棱边的材料幅面。
所述任务通过一种根据权利要求1所述的卷绕装置来解决。优选的实施方式从从属权利要求中产生。
按照本发明，为所述子材料幅面的每条棱边设置了翻折元件。用第一振荡装置能够使所述至少一把刀横向于运行方向运动。用第二振荡装置能够使用于子材料幅面的沿着运行方向看的左棱边的翻折元件横向于运行方向运动。用第三振荡装置使用于子材料幅面的沿着运行方向看的右棱边的翻折元件横向于运行方向运动。用控制单元能够如此操控所述第一振荡装置、第二振荡装置和第三振荡装置，使得所述子材料幅面的被翻折的棱边能够错开地卷起。
与已知的卷绕装置相比，用所述按本发明的卷绕装置能够调节被翻折的棱边的宽度。对于变化的机器参数来说，被翻折的棱边的宽度能够以相应的方式由所述控制单元来保持恒定。通过这种方式，总是能够在振荡的刀的一个周期的期间卷起相同数量的薄膜层，由此能够有效地降低薄膜上的折皱的产生。
根据一种优选的实施方式来规定，所述第一振荡装置、第二振荡装置和第三振荡装置分别由一个由马达驱动的偏心轮来构成。
根据另一种优选的实施方式来规定，通过所述控制单元能够分开地调节所述第一振荡装置、第二振荡装置和第三振荡装置的频率。
根据另一种优选的实施方式来规定，通过所述控制单元能够分开地调节所述第一振荡装置、第二振荡装置和第三振荡装置的行程。
根据另一种优选的实施方式来规定，测量所卷起的卷筒的厚度分布并且将其传送给所述控制单元。
根据另一种优选的实施方式来规定，测量所述材料幅面的幅面速度并且将其传送给所述控制单元。
根据另一种优选的实施方式来规定，所述材料幅面是在浇铸薄膜设备上或者在吹塑薄膜设备上制造的伸拉膜。
附图说明
借助于附图对本发明的另外的细节和优点进行描述。
图1示出了按照本发明的第一种实施方式的刀梁的原理图；
图2示出了按照本发明的第二种实施方式的刀梁的原理图；
图3示出了按本发明的翻折装置的俯视图；并且
图4示出了按照图3的视图的透视图。
具体实施方式
图1示出了按照本发明的第一种实施方式的刀梁的原理图。所述材料幅面101是在浇铸薄膜设备上制造的伸拉膜。
所述伸拉膜101在其制造之后沿着方向102来运送并且由此到达刀梁103处。所述刀梁103通过振荡装置沿着方向104来回运动并且总共具有5把切割刀105。在边缘上在左边并且在右边分别产生边角料111和112，能够为了其他用途而继续对其进行加工。
在所述刀梁103的后面产生S形的条带106、107、108和109并且更确切地说以如在图1中所示出的一样的形状来产生所述条带。所述S形的边缘在此不必绝对是均匀的。所述振荡装置的运动的幅度和频率也能够是不规则的。除此以外，也能够考虑，各把刀105单个地被操控并且由此执行不同的运动。
图2示出了按照本发明的第二种实施方式的刀梁的原理图。所述材料幅面201又是在浇铸薄膜设备上制造的伸拉膜。
所述伸拉膜201在其制造之后沿着方向202被运送并且由此到达刀梁203处。所述刀梁203通过振荡装置沿着方向204来回运动并且总共具有3把切割刀205。因为左右两边的最外面的边缘未被切割，所以与按照图1的实施方式相比没有产生边角料。
在所述刀梁203的后面产生S形的条带206、207、208和209并且更确切地说以如在图2中所示出的一样的形状产生所述条带。所述S形的边缘在此不必绝对是均匀的。所述振荡装置的运动的幅度和频率也能够是不规则的。除此以外，也能够考虑，各把刀205单个地被操控并且由此执行不同的运动。
最外面的条带206和209分别具有笔直的和S形的边缘并且以这种形状为特殊的用途而继续被加工。
图3示出了按本发明的翻折装置的俯视图。所述翻折装置沿着运行方向看处于如比如按照图1或者按照图2所描述的一样的刀梁的后面。所述翻折装置由横杆301构成，第一导轨302和第二导轨303被固定在所述横杆上。四个子材料幅面305、306、307和308沿着运行方向304运行，所述四个子材料幅面此前在所述刀梁103或者203处被从整个宽度范围内运行的材料幅面中分割出来。
所述翻折装置如此设计而成，从而为所述子材料幅面305、306、307和308的每条棱边设置了翻折元件。在所述第一导轨302上，所述翻折元件309、310、311和312可移动地得到导引，所述翻折元件由此沿着运行方向304看对所述子材料幅面305、306、307和308的左棱边进行翻折。以相应的方式，在所述第二导轨303上所述翻折元件313、314、315和316可移动地得到导引，所述翻折元件由此沿着运行方向304看对所述子材料幅面305、306、307、308的右棱边进行翻折。
所述翻折元件309、310、311和312与传动杆318相连接，所述传动杆由偏心轮马达317来驱动。以相应的方式，所述翻折元件313、314、315和316与由偏心轮马达319驱动的传动杆320相连接。
第一振荡装置已经参照按照图1的刀梁103或者参照按照图2的刀梁203进行了描述。除此以外，所述偏心轮马达317代表着第二振荡装置，用所述第二振荡装置能够使用于子材料幅面的沿着运行方向304看的左棱边的翻折元件309、310、311和312横向于运行方向运动。以相应的方式，所述偏心轮马达319代表着第三振荡装置，用所述第三振荡装置能够使用于子材料幅面的沿着运行方向304看的右棱边的翻折元件313、314、315和316横向于运行方向304运动。
下面对所述第二振荡装置的作用原理进行描述。相应的描述也适用于所述第三振荡装置。所述偏心轮马达317的转动运动被转换为所述翻折元件309、310、311和312的横向于运行方向304的线性运动。所述偏心轮马达317在此不是连续地转动，而是在预先给定的角分段之内执行变换的部分转动。由此，用所述角分段的张角能够调节所述翻折元件309、310、311和312的行程。此外，变换的部分转动的频率相应于所述翻折元件309、310、311和312的运动频率。如果所述翻折元件309、310、311和312和翻折元件313、314、315和316的往复直线运动相对于彼此以偏移来执行，则对此能够调节被翻折的棱边的宽度。
所述三个振荡单元的频率和行程通过控制单元来如此彼此协调，使得所述子材料幅面的被翻折的棱边能够错开地卷起，从而避免上面所提到的棱边堆积。
图4示出了按照图3的视图A的透视图。相同的部件设有相同的附图标记，因而就此而言要参照按照图3的描述。除此以外，在按照图4的图示中可以看出，每个翻折元件具有能操控的升降缸，其中为简明起见在图4中仅仅所述翻折元件313的升降缸用附图标记401来表示。借助于所述升降缸，所述翻折元件能够分别相对于幅面路径摆动到里面或者摆动出来。通过这种方式，比如可以减小用于新订单的调试时间，方法是：操作者能够通过相应的机器指令来控制多个翻折元件的同时的向里摆动。此外，在干扰时能够避免间接损失，方法是：在识别出干扰时使所述翻折元件从幅面路径中摆动出来。
