本申请涉及上料技术领域，特别是涉及一种上料装置和上料方法。
背景技术
随着工业领域的自动化技术的逐渐发展，对于上料的自动化要求也越来越高。实际生产中，在使用上料装置进行上料的过程中，难以准确预估余料的长度，因此需要在还剩余一定余料的情况下，降低上料速度，同时人工关注余料长度，在余料长度接近零时手动停机。一方面，该上料过程对于人工的依赖程度较高，不利于自动化程度的提高；另一方面，减速时间过长，不利于生产效率的提高。
因此，如何提供一种上料装置和上料方法，以提高生产效率和自动化程度是一项亟待解决的技术问题。

随着工业领域的自动化技术的逐渐发展，对于上料的自动化要求也越来越高。实际生产中，在使用上料装置进行上料的过程中，难以准确预估余料的长度，因此需要在还剩余一定余料的情况下，降低上料速度，同时人工关注余料长度，在余料长度接近零时手动停机。一方面，该上料过程对于人工的依赖程度较高，不利于自动化程度的提高；另一方面，减速时间过长，不利于生产效率的提高。
基于此，本申请提供了一种上料装置，上料装置包括卷轴、传感器和控制单元。卷轴上设置有料卷，上料装置用于转动卷轴以输送料卷中的料带。传感器用于感测料卷信息并将料卷信息发送至控制单元。控制单元用于根据料卷信息控制卷轴的转动状态。这样，可以利用传感器检测料卷的状态并感测料卷信息，从而便于控制单元根据料卷信息控制卷轴的转动状态，例如，根据料卷信息控制卷轴减速、停止转动等。一方面，通过传感器的设置，可以检测到料卷信息；另一方面，通过控制单元的设置，可以根据料卷信息，及时控制卷轴的转动状态。因此，在本申请实施例的方案中，一方面，不需要人工实时关注料卷状态，从而可以减小对人工的依赖程度，提高自动化程度；另一方面，可以在料卷状态发生变化时及时控制卷轴的转动状态，有利于提高生产效率。

料卷12包括料带121，也可以说，料卷12由料带121卷绕形成。在使用上料装置1进行上料的过程中，随着卷轴11的转动，料卷12中的料带121在上料装置1 的作用下，被输送至目的地。
上料装置1用于转动卷轴11以输送料卷12中的料带121，可以包括以下情况。例如，上料装置1包括驱动单元，例如马达，马达与卷轴11连接以驱动卷轴11转动，随着卷轴11的转动，料卷12逐渐放出料带121，从而上料装置1(例如上料装置的输送单元)输送料带121。
料卷12可以为工业生产中所需要输送的材料，例如，料卷12为一卷极片。本申请对料卷12的具体材料和种类不作具体限制。
图2为本申请一实施例的上料装置的示意图。结合图1和图2所示，上料装置1还包括传感器13和控制单元14。

料卷信息可以为与料卷12的状态有关的信息。料卷信息可以包括料卷12的余料信息，例如，料卷12中剩余的料带的长度，料卷12的走带长度；料卷信息还可以包括断料信息，例如料带121的出卷位置发生断料等。
传感器13可以为测距传感器、测厚传感器、光电传感器等，只要可以感测料卷信息即可，本申请实施例对此不作具体限制。
控制单元14用于根据料卷信息控制卷轴11的转动状态。
控制单元14可以根据料卷信息控制卷轴11开始转动，停止转动或减小转动速度等。也就是说，控制单元14可以根据料卷信息灵活地控制卷轴11的转动状态。
在本申请实施例中，上料装置1包括卷轴11、传感器13和控制单元14。卷轴11上设置有料卷12，上料装置1用于转动卷轴11以输送料卷12中的料带121。传感器13用于感测料卷信息并将料卷信息发送至控制单元14。控制单元14用于根据料卷信息控制卷轴11的转动状态。这样，可以利用传感器13检测料卷12的状态并感测料卷信息，从而便于控制单元14根据料卷信息控制卷轴11的转动状态，例如，根据料卷信息控制卷轴11减速、停止转动等。一方面，通过传感器13的设置，可以检测到料卷信息；另一方面，通过控制单元14的设置，可以根据料卷信息，及时控制卷轴11的转动状态。因此，在本申请实施例的方案中，一方面，不需要人工实时关注料卷状态，从而可以减小对人工的依赖程度，提高自动化程度；另一方面，可以在料卷状态发生变化时及时控制卷轴11的转动状态，有利于提高生产效率。
在一实施例中，传感器13设置于料带121的出卷位置B，传感器13用于感测第一信息并将第一信息发送至控制单元14，第一信息用于指示料带121的出卷位置B发生断料；控制单元14用于根据第一信息控制卷轴11停止转动。
第一信息可以为数字信号，例如数字信号的值与数值1相对应时，代表此时发生断料；数字信号的值与数值0对应时，代表此时未发生断料。
出卷位置B可以为料带121沿料带121的输送方向A-A开始输送的位置。
断料可以指料带121在出卷位置B处断开，其可以包括料卷已全部用完，料卷中的余料长度为0这种情况，也可以包括料带121因缺陷而在出卷位置B处断开这种情况。
控制单元14用于根据第一信息控制卷轴11停止转动。这样，在发生断料的情况下，控制单元14可以控制卷轴11停止转动。相比于在料卷12还剩余一定余料的情况下，就对卷轴进行减速，本申请的技术方案可以减少卷轴11的减速时间，有利于提高生产效率；此外，相比于通过人工判断是否断料，本申请的技术方案可以减少对人工的依赖程度，提高自动化程度；同时还可以避免因人工失误造成的误判，从而可以避免卷轴过早停止转动或过晚停止转动，可以兼顾生产效率和生产安全性。
可选地，控制单元14控制卷轴11停止转动，可以为控制单元14控制卷轴11在预设时间内停止转动，预设时间可以根据实际转轴11的转速等具体设置。

可选地，上料装置1还可以包括输送单元。输送单元可以用于输送料带121，输送单元输送料带121的速度可以与料卷12放出料带121的速度相同，也即，与转轴11的转速相关，例如，与转轴11的线速度相同。
可选地，控制单元14在控制卷轴11停止转动或减速的同时，也可以同时控制输送单元的停止运行或减速。
可选地，输送单元包括纠偏机构15，抚平装置16和辊轴17等中的至少一个。例如，沿料带121的输送方向A-A，纠偏机构15，抚平装置16和辊轴17依次设置。纠偏机构15和辊轴17可以用于使料带121沿特定的输送方向输送，抚平装置16可以用于减小料带121表面的打皱。本申请对于偏机构15，抚平装置16和辊轴17的具体结构不作限制。
可选地，控制单元14还可以根据第一信息控制上料装置1中的其他输送单元停止工作，以停止对料带121的输送。
本申请的上料装置1可以应用于工业生产领域，例如，应用于模切、分条等领域。
在该实施例中，传感器13设置于料带121的出卷位置B，传感器13用于感测第一信息并将第一信息发送至控制单元14，第一信息用于指示料带121的出卷位置B发生断料。控制单元14用于根据第一信息控制卷轴11停止转动。这样，可以利用传感器13及时检测到断料的发生，从而在发生断料的情况下，控制单元14可以及时控制卷轴11停止转动。一方面，通过传感器13的设置，可以检测到断料的发生；另一方面，通过控制单元14的设置，可以在断料发生时，及时控制卷轴11停止转动。因此，在该实施例的方案中，一方面，不需要人工实时关注余料长度，从而可以减小对人工的依赖程度，提高自动化程度；另一方面，可以在断料时及时控制卷轴11停止转动，从而可以减小转轴11的减速时间，提高生产效率。
在一实施例中，上料装置1还包括料夹18，料夹18相对于传感器13沿料带121的输送方向远离卷轴11；控制单元14还用于：根据第一信息，控制料夹18夹紧料带121，以阻止料带121的料尾从料夹18滑出。
料夹18为固定料带121的一种结构，料夹18用于在卷轴11停止转动的同时，固定料带121以防止料带121继续移动。
图3为本申请一实施例的料夹的示意图。如图3所示，料夹18包括相对设置的滚轮181。在料夹18夹紧料带121的过程中，滚轮181贴附料带121滚动，起到固定料带121并阻止料带121沿输送方向移动的作用。
在该实施例中，在发生断料时，控制单元14根据第一信息控制卷轴11停止转动，同时控制单元14同步控制料夹18夹紧料带121，避免料带121的料尾从料夹18滑出。这样，可以避免料尾脱离料夹和/或输送单元，从而可以避免人工重新走料，有利于提高生产效率和生产质量。
在一实施例中，上料装置1还包括余料测量单元19，余料测量单元19用于测量料卷12中的余料的长度信息并将料卷12中的余料的长度信息发送给控制单元14；控制单元14还用于：在根据第一信息控制卷轴11停止转动之前，根据余料的长度信息控制卷轴11减速。
可选地，余料测量单元19为测距仪，测距仪设置于距离卷轴11的一定距离的固定位置处，从而可以根据测距仪与料卷12之间的距离计算料卷12中的余料的长度。
料卷12中的余料的长度信息可以为与余料的长度有关的信息，例如余料的长度，料卷的走带长度等。通过余料的长度信息可以计算出余料的长度。
在该实施例中，通过余料测量单元19可以检测料卷12的余料长度信息，从而控制单元14可以根据余料的长度信息控制卷轴11减速，以便在发生断料时及时控制卷轴11停止转动。
在一实施例中，余料测量单元19包括第一余料测量单元191和第二余料测量单元192。
第一余料测量单元191相对于传感器13沿料带121的输送方向远离卷轴11，第一余料测量单元191用于测量料卷12的走带长度并将料卷12的走带长度发送给控制单元14。
料卷12的走带长度可以为，料卷12中的已经输送的料带的长度，例如，经过第一余料测量单元191的料带的长度。
可选地，第一余料测量单元191设置于料夹18之后，即，在料带121的输送过程中，料带先经过料夹18，再经过第一余料测量单元191所在的位置。例如，第一余料测量单元191设置于料夹18之后3米的位置处。
可选地，第一余料测量单元191为计数编码器，料卷12的走带长度L p＝n*2πR 1，其中，n为计数编码器轮的转动的圈数，R 1为记数编码器轮的半径。第一余料测量单元191可以为输送单元的一部分，料带121在输送的过程中与第一余料测量单元191接触，这样，第一余料测量单元191可以测量得到料卷12的走带长度。
第二余料测量单元192用于测量第二余料测量单元192与料卷12之间的当前距离并将该当前距离发送给控制单元14。
随着上料装置1对料带121的输送，料卷12的厚度逐渐减小，料卷12与第二余料测量单元192之间的距离也逐渐增大。料卷12的厚度减小值为料卷12与第二余料测量单元192之间的初始距离d 1与料卷12与第二余料测量单元192之间的当前距离d 2之间的差值。
料卷12与第二余料测量单元192之间的距离可以为料卷12的第一侧与第 二余料测量单元192之间的直线距离，其中，料卷12的第一侧可以为，料卷12作为一个整体，沿料卷12的径向方向，远离卷轴11的一侧。
可选地，第二余料测量单元192为测距传感器，该测距传感器设置于距离卷轴11的一定位置处。本申请对第二余料测量单元192的具体设置位置不作具体限定，只要可以测得距离料卷12的距离即可。
在该实施例中，分别通过第一余料测量单元191和第二余料测量单元192获取余料的长度信息，相比于只通过一种方式获得料卷的余料的长度信息，通过结合第一余料测量单元191和第二余料测量单元192获得的余料的长度信息，可以提高获取到的料卷的余料的长度信息的准确性。
在一实施例中，控制单元14用于：根据料卷12的走带长度，计算第一余料长度；根据当前距离，计算第二余料长度；在第一余料长度和第二余料长度中的较小的一个达到第一阈值的情况下，控制卷轴11减速至第一速度；在第一余料长度和第二余料长度中的较大的一个达到第一阈值的情况下，控制卷轴11减速至第二速度，第二速度小于第一速度。
料卷12中的料带的初始总长为L 0，第一余料长度L 1＝L 0-L p；第二余料长度L 2＝L 0-2π(d 2-d 1)，其中，d 2为第二余料测量单元192与料卷12之间的当前距离，d 1为第二余料测量单元192与料卷12之间的初始距离。
可选地，第一余料测量单元191可以在计算出第一余料长度后，将第一余料长度发送给控制单元14。

可选地，第一余料长度的误差小于2米。
可选地，第二余料长度的误差小于1米。
第一阈值可以根据实际情况具体设置，例如第一阈值为料卷12的总长度的5％。
在该实施例中，控制单元14可以获取同一时刻的第一余料长度和第二余料长度，第一余料长度和第二余料长度因第一余料测量单元和第二余料测量单元的不同可能会有所差异。在第一余料长度和第二余料长度中的任意一个达到第一阈值，例如小于或等于第一阈值时，控制单元14控制转轴减速至第一速度；在第一余料长度和第 二余料长度中的另一个达到第一阈值时，控制单元14控制转轴减速至第二速度。这样，既可以控制转轴11提前减速，又可以避免转轴11的减速时间过长导致的生产效率的降低。
在该实施例中，相比于只通过第二余料长度或第一余料长度控制卷轴11减速，该实施例中的方案结合第一余料长度和第二余料长度，既可以避免卷轴11过早减速导致的减速时间过长，又可以避免卷轴11减速较晚导致的卷轴11难以在断料时停止，从而可以兼顾生产效率和安全性。
在一实施例中，第一速度为卷轴11的预定速度的50％，第二速度为卷轴11的预定速度的25％。这样，可以快速有效地实现卷轴11的减速，同时也有利于在发生断料时，实现卷轴11的快速停转。
卷轴11的预定速度可以为在正常输送料带121的过程中，卷轴11的转速。
可选地，第一速度和第二速度可以根据实际情况具体设置，例如第一速度为卷轴11的预定速度的30％，第二速度为卷轴11的预定速度的5％。
在一实施例中，上料装置1还包括换料单元10。控制单元14用于：在根据第一信息控制卷轴11停止转动之后，根据第一信息，控制换料单元10更换料卷12。
在该实施例中，在控制单元14根据第一信息控制卷轴11停止转动后，控制单元14根据第一信息控制换料单元10更换料卷12。也就是说，只要在出卷位置B发生断料，就进行换卷操作，其中，出卷位置B发生断料可以包括料卷为空料卷的情况，也可以包括料卷不是空料卷，但料带因为缺陷发生断裂的情况。这样，实现了断料后换料的自动化，提高了上料装置1的自动化程度。此外，在该换料工序中，不需要工人进入换料平台进行换料，有利于提高生产的安全性。
可选地，控制单元14还用于：在根据第一信息控制卷轴11停止转动之后，根据第一信息和第二信息，第二信息用于指示料卷12为空料卷12。这样，避免料卷12未用完就进行换卷的情况。
可选地，第二信息可以根据第二余料测量单元192获得。
在一实施例中，换料单元10包括自动导引运输车(Automated Guided Vehicle，AGV)；控制单元14还用于：根据第一信息，控制自动导引运输车取出卷轴11并将新料卷安装于卷轴11。这样，通过自动导引运输车就可以自动完成换料，提高了自动化程度。

在一实施例中，换料单元10包括气缸和自动导引运输车，气缸与卷轴11连接；控制单元14还用于：根据第一信息，控制气缸顶出卷轴11，控制自动导引运输车将新料卷安装于卷轴11。这样，通过气缸顶出空卷轴11，通过自动导引运输车安装新料卷，实现了换料的自动化。
可选地，上料装置1还可以包括接带平台，接带平台沿料带121的输送方向相对于料夹18远离卷轴11；在控制单元14控制换料单元10完成换料后，可以由人工在接带平台进行接带操作，即，将新料卷与上个料卷的剩余的料带的料尾连接。
在一实施例中，传感器13为光电传感器。这样，通过光电传感器接收到的光通量的变化，可以及时检测到断料的发生。
传感器13可以通过识别接收到光通量发生变化而输出动作信号，比如为遮光式光电传感器、扩散发射型光电开关等。
传感器13可以沿平行与料带121的厚度方向设置并垂直于料带121的输送方向，在料带121未发生断料时，传感器13接收到的光通量在一定的范围内；当料带121发生断料时，传感器13接收到的光通量发生较大变化，当接收到的光通量超过上述范围时，传感器13可以产生第一信息。
