在一种实施方式中，传动机构包括凸轮和连杆，连杆的一端转动且偏心连接在凸轮上，另一端铰接连接在刀具31上，第二驱动机构驱动凸轮转动，并带动连杆摆动，在刀架32 轨道321的限制作用下，连杆驱动刀具31实现往复直线运动。
在一个具体的实施例中，参照图2，传动机构33包括传动轴331、第一凸轮332和第二凸轮333。第一凸轮332、第二凸轮333分别同轴地连接在传动轴331的两端，传动轴331转动时能够驱动两个凸轮(332、333)同步转动。传动机构33还包括第一连杆334和第二连杆335。第一连杆334的其中一端与第一凸轮332偏心连接，另一端与刀具31铰接连接，第二连杆335的其中一端与第二凸轮333偏心连接，另一端与刀具31铰接。传动轴331被配置为：通过第一凸轮332、第二凸轮333驱动第一连杆334、第二连杆335同步运动，进而带动刀具31运动。
第一凸轮332和第一连杆334可以设置在运输组件2的其中一侧，第二凸轮333和第二连杆335可以设置在运输组件2的另一侧；第一连杆334可以连接在刀具31的其中一端，第二连杆335可以连接在刀具31的另一端，避免干涉运输组件2上的物料。通过上述结构，传动机构33能够同时向刀具31的两端传递驱动力，避免刀具31上的应力过于集中而导致刀具31变形。
具体地，传动轴331可以横向地设置在运输组件2的下方，并且与运输组件2的延伸方向垂直，传动轴331可以通过若干个轴座安装在架体1上。第二驱动机构与传动轴331传动连接，驱动传动轴331转动。第二驱动机构包括电机，电机的输出端可以直接同轴连接传动轴331，也可以通过齿轮、皮带等部件与传动轴331传动连接，本公开中对此不做限定。
图4是本公开一实施例提供的去除防护罩的切割装置的结构示意图。在一些实施方式，如图4所示，架体1上设置有挡板12，挡板12挡设在运输组件2的相对两侧，并且高于运输组件2的承载面，挡板12能够对运输组件2上的物料5进行限制，防止物料5从运输组件2两侧掉落。
在一个具体的实施例中，运输组件2的传送带24至少部分露出箱型结构的架体1，输组件2两侧的挡板12可以倾斜设置，并且可以在运输组件的两侧形成扩口，便于将物料放置到运输组件2上。两侧挡板12的顶部可以向相对的方向水平翻折，构成平台，平台上可以开设孔或槽，以供刀架32、传动组件33向上伸出。
在一些实施方式中，参照图4，架体1上还设置有导向组件，导向组件被配置为：沿着运输组件2的延伸方向设置，对运输组件2上的物料5进行导向。导向组件可以设置在运输组件2的相对两侧或者上方，并且高于挡板12的高度。导向组件可以包括但不限于导向杆、导向板、导向辊轮等结构，只要能够对运输组件2上的物料进行导向即可。
在一种实施方式中，导向组件包括多个导向辊4，多个导向辊4可以分布在运输组件2的上方或着两侧，导向辊4可以竖立设置、横向设置或者倾斜设置。导向辊4可以沿着运输组件2的延伸方排列设置，运输组件2每侧至少设置有一个导向辊4。多个导向辊4可以从运输组件2的上料端21排列至下料端22，也可以仅排布在上料端21、下料端22之间的部分区域。例如，导向辊4只分布在运输组件的上料端21与切割组件3之间。导 向辊4与物料接触时能够相对物料滚动，产生的摩擦阻力较小。
在一种实施方式中，运输组件2的两侧均设置有挡板12和导向辊4，并且，导向辊4的位置高于挡板12。具体地，导向辊4可以安装在挡板12的顶部边缘从处。对于体型较大的物料，例如冬瓜，在运输组件2上运动时，超出两侧挡板12之间的范围，能够与导向辊4之间产生滚动摩擦，导向辊4对物料造成的阻力较小，以使物料能够在运输组件2上顺利运送。
在一些实施方式中，参照图4，导向辊4包括固定导向辊41和倾斜导向辊42。其中，固定导向辊41至少设置在运输组件2的其中一侧，固定导向辊41可以沿着运输组件2的延伸方向排列，固定导向辊41均竖立设置，且位置相对架体1固定。倾斜导向辊42，至少设置在运输组件2的其中一侧，倾斜导向辊42以上端逐渐靠近运输组件2的方式倾斜设置，能够压设在物料4上，对物料5起到限位作用。
倾斜导向辊42可以通过活动结构连接在架体1上，其倾斜角度能够通过活动结构进行调整，活动结构可以是铰接结构、弹性装置等，以适应不同大小的物料。倾斜导向辊42的位置可以通过限位结构进行限定，限位结构可以是锁紧螺栓、阻尼装置等。当倾斜导向辊42根据物料调整好角度并压住物料后，通过限位结构进行限定，使倾斜导向辊42能够相对架体1固定。物料5被切割时，在刀具31的压力作用下可能出现晃动，影响切割精度，倾斜导向辊42能够有效的对物料5进行限定，从而提高切割精度，减少损耗。在较佳的实施例中，倾斜导向辊42的位置可以靠近切割组件3，从而更好的起到限定作用。
在一个具体实施例中，参照图4，运输组件2的其中一侧排列设置有多个固定导向辊41，另一侧设置有一个倾斜导向辊42。固定导向辊4和倾斜导向辊42均设置在运输组件2的上料端21和切割组件3之间，并且，倾斜导向辊42的位置靠近于切割组件3。工作人员可以站在倾斜导向辊42所在的一侧，将物料5放至运输组件2，并且对倾斜导向辊42进行调整。
在一种些实施方式中，参照图1，架体1上可以设置有防护罩13，防护罩13至少罩设在切割组件3的外部。切割组件3具有一定的危险性，防护罩13罩设在切割组件3外部，能够防止工作人员直接接触切割组件3，提高安全性。此外，防护罩13上应当留有供物料5进出的开口。
实施例二
本实施例与实施例一的不同之处在于，切割装置还包括控制系统，控制系统被配置为控制运输组件2和切割组件3启闭和运动速度。重复部分在此不再赘述。
物料为生鲜产品时，物料的外形大多不规则，例如冬瓜、萝卜、玉米等，运输组件2和切割组件3的行程一定时，物料切割成的单份成品长度均匀，但重量不均匀。对此，可以在控制系统内设置预设算法，调整运输组件2和切割组件3的相对运动速度。
具体的，控制系统可以向第一驱动机构的电机、第二驱动机构的电机分别发送控制信号，控制电机的启闭和转速，从而控制运输组件2和切割组件3启闭和运动速度。通过调 整控制运输组件2和切割组件3之间的相对运动速度，能够控制物料5被切割的长度。
在一种实施方式中，如图5所示，切割装置还包括称重单元61和测量单元62。其中，称重单元61被配置为获取物料5的重量数据T；测量单元62被配置为至少获取物料5的长度数据L。称重单元61、测量单元62能够将获得的重量数据T、长度数据L发送至控制系统。
在一种实施方式中，测量单元62能够检测物料5的轮廓数据，包括物料的长度数据L以及物料每一处的径向尺寸数据，由于冬瓜等生鲜产品的形状通常是不规则的，因此测量单元62获得的物料每一处的径向尺寸数据存在差别。
称重单元可以是压力传感器等，测量单元可以采用三维成像模组，例如深度相机或全景相机等摄像装置。本领域技术人员能够想到的其他类型的常规的用于测量物料重量、长度、轮廓等数据的装置均包含在本公开的保护范围之内。
切割装置可以包括信息采集位置6。信息采集位置6可以设置用于放置物料的平台。称重单元61和测量单元62设置在信息采集位置6处，称重单元61能够获取放置在信息采集位置平台上的物料的重量数据T，测量单元62至少能够获取放置在信息采集位置的物料的长度数据L。
信息采集位置6可以与架体1设置在一起或者分开设置。工作时，先将物料5放置在信息采集位置6上，通过称重单元、测量单元获取物料的重量数据T、长度数据L，然后将物料5转移到运输组件2的上料端21。
在一种实施方式中，如图5所示，信息采集位置6与架体1设置在一起。将信息采集位置6处的平台设置在运输组件2的上料端21处，并且与运输组件2的承载面齐平，在信息采集位置6上通过称重单元61、测量单元62获取物料5的重量数据T、长度数据L后，可以直接将物料5推送到运输组件2的上料端21。进一步地，信息采集位置6处的平台上可以设置输送装置，例如电致动的输送辊、输送带等等，能够代替人工直接将平台上的物料5运送至齐平的输送组件2的上料端21，使用更加便利。
详细地，称重单元61可以采用压力传感器，并且设置在信息采集位置6的平台上，物料放置在平台后，压力传感器能够检测到物料对平台产生的压力，从而生成物料的重量数据T。测量单元62可以采用摄像装置，并且设置在信息采集位置的上方或侧边，能够扫描放置在信息采集位置平台上的物料，获取物料的长度数据L。具体地，测量单元62可以通过连接在平台或者架体1上的支架支撑在信息采集位置的上方。
控制系统具有预设算法，控制系统被配置为：基于重量数据T、长度数据L、预设的物料的单份目标标准重量T′，以及预设的修正因数，通过预设算法进行计算，得到单份目标长度L′；然后基于单份目标长度L′调整运输组件2和切割组件3的相对运动速度，将外形不规则的物料精确的切割成长度为单份目标长度L′且重量均匀的单份成品。
在一种实施方式中，如图5所示，切割装置还包括控制面板7，控制面板7可以采用显示屏和控制按钮，或者控制面板可以直接采用触控板。控制面板7与控制系统电连接或 通信连接。控制面板7上设置有开启、关闭、暂停等控制按钮，并且控制面板7能够显示代表运输组件2和切割组件3的工作状态的数据，例如第一驱动机构、第二驱动机构的交流电频率、输出功率，切割组件3每刀切割出的成品的实际长度等等。通过控制面板7可以向控制系统预设物料的单份目标标准重量T′、修正因数等参数。
控制系统、控制面板可以集成在切割装置的架体1上，也可以分开设置，实现对切割装置进行远程控制。
切割装置上还可以设置报警单元，报警装置可以设置为对第一驱动机构的电机、第二驱动机构的电机的工作状态进行检测，当检测到工作状态达到报警预设值时，报警装置被触发。报警装置被触发后可以采用发出提示音、亮起警示灯等方式进行报警，还可以将异常情况显示在控制面板7上。控制面板7上可以设置关闭警报单元的控制按钮。
控制系统可以设置自动和手动两种控制模式。在自动模式下，控制系统根据预设算法进行计算，得到切割物料的单份目标长度L′，然后基于单份目标长度L′自动调整运输组件2和切割组件3的相对运动速度，将物料切割成长度为单份目标长度L′的成品。在手动模式下，工作人员可以通过控制面板7自主调整运输组件2和切割组件3的相对运动速度，将物料切割成任意的长度。手动模式能够弥补自动模式在灵活性、可控性方面的缺点，使切割装置的功能更加完善。
实施例三
本公开还提供了一种应用于上述切割装置的切割方法，如图6所示，包括：
S100、获取物料的重量数据T和长度数据L。
工作时，将物料放置在信息采集位置上，称重单元、测量单元能够对信息采集位置上的物料进行检测，获取物料的重量数据T、长度数据L，并且能够将获得的重量数据T、长度数据L发送至控制系统。采集数据后，将物料从信息采集位置运送到运输组件的上料端。
S200、基于预设的单份目标标准重量T′和修正因数、以及重量数据T、长度数据L通过预设算法进行计算，得到单份目标长度L′。
通过控制面板向控制系统预先设定单份目标标准重量T′和修正因数。其中，单份目标标准重量T′是需要切割物料得到的单份成品的重量，修正因数用于修正物料的在切割过程中的长度损耗或物料外形的不规则等因素所造成的误差，提高预设算法的计算精度。
具体地，修正因数包括数量修正因素X，数量修正因素X为容许物料损耗的成品数量。预设算法包括：
基于预设的单份目标标准重量T′以及重量数据T，确定重量比值。其中，重量比值可以是重量数据T：单份目标标准重量T′的比值。
基于重量比值和数量修正因数X确定修正差值。其中，修正差值可以是重量比值减去数量修正因数X的差值。
基于修正差值和长度数据L，获得单份目标长度L′。其中，单份目标长度L′可以是长度数据L：修正差值的比值。
将物料根据所需的预设单份目标标准重量T′切割成若干份成品时，会存在一定的损耗。比如，物料的重量数据T为14kg，需要的预设单份目标标准重量T′为500G，加工出的每份成品重量大于或等于500g时才算成品，理论上可以产出28份成品，但是，由于精度误差，实际的切割过程中会出现损耗，有的成品可能重量大于500g,有的成品可能重量小于500g而成为废品。因此，在确定产出的成品数量时，可以减少X份，数量修正因素X是为了容许损耗而减去的成品数量，减少重量小于500g的废品。
S300、将单份目标长度L′发送至切割装置，控制切割装置将物料切割成长度为单份目标长度L′的成品。
控制系统通过控制运输组件的第一驱动机构和/或切割组件的第二驱动机构，能够调整运输组件和切割组件的相对运动速度，运输组件的运动行程在切割组件切割动作的间隔时间内为单份目标长度L′，以使切割组件基于相对运行速度，将物料切割成长度为单份目标长度L′的成品。
在本实施例的切割方法中，控制系统基于预设单份目标标准重量T′和数量修正因数X，以及物料的重量数据T和长度数据L，通过预设算法计算出了单份目标长度L′，并切割装置调整运输组件和切割组件的相对运动速度，将物料切割成单份目标长度L′的成品，切割出的每份成品的重量为单份目标标准重量T′。相对于目前的人工切割方式，本公开的切割方法有效节省的了人力劳动，并且提高了成品重量的精确度。
实施例四
本公开还提供了一种应用于上述切割装置的切割方法，与实施三公开的方法的不同之处在于，本实施例的方法还包括：获得物料的轮廓数据，轮廓数据包括物料的长度数据L和物料的径向尺寸数据。
切割装置的测量单元为摄像装置，能够获取物料的整体轮廓数据，并将轮廓数据发送至控制系统。轮廓数据包括物料的长度数据L和物料每一处的径向尺寸数据。
本实施例中，修正因数包括数量修正因素X和长度修正因数Y，数量修正因素X是用于容许切割损耗而减去的成品数量，长度修正因数Y用来修正物料外形不规则所带来的误差。
本实施例中，步骤S200的预设算法包括：
基于预设的单份目标标准重量T′以及重量数据T，确定重量比值。其中，重量比值可以是重量数据T：单份目标标准重量T′的比值。
基于重量比值和数量修正因数X确定修正差值。其中，修正差值可以是重量比值减去数量修正因数X的差值。
基于修正差值和长度数据L，确定修正比值。其中，修正比值可以是长度数据L：修正差值的比值。
基于修正比值和长度修正因数Y，获得单份目标长度L′。其中，单份目标长度L′可以是修正比值减去长度修正因数Y的差值。
Y值可以设定为范围值或者多个数值，可以通过对物料体积的精密计算获得，也可以通过一定量实际数据的积累进行确定。并且，长度修正因数Y设置为与物料的轮廓数据的径向尺寸呈负相关。
例如，将长度修正因数Y设置为0、0.5和1，控制装系可以统根据物料的径向尺寸数据调整Y值的大小。当物料运动至切割组件的部分径向尺寸在60cm-55cm之间时，将Y值调整为0，当物料运动至切割组件的部分径向尺寸在55cm-50cm之间时，将Y值调整为0.5，当物料运动至切割组件的部分径向尺寸在50cm-45cm之间时，将Y值调整为1。当物料被切割的部分径向尺寸越小，Y值则需要调整的越大，以增加计算出的单份目标长度L′，弥补切割出的成品的体积，实现将物料精确地切割成重量均匀的单份成品。
本实施例的切割方法中，在预设公式中设置长度修正因数Y，有效的修正了物料外形不规则所带来的误差，从而使切割装置能够更加精确的切割出重量均匀的单份成品，提高了工作产成率。
在一种应用场景中，通过切割装置将冬瓜切割成多分成品。冬瓜的两端处形状不规则，其两端切割出的成品误差较大，因此，加工前可以先人工将冬瓜两端的不规则处切除，然后再放入切割装置。
操作时，将去除两端的冬瓜放置在信息采集位置上，通过称重单元、测量单元检测物料的重量数据T和轮廓数据，并通过控制面板向控制系统预设单份目标标准重量T′，以及数量修正因素X和长度修正因数Y。
然后将冬瓜以图1所示的姿态运送到运输组件2的上料端22；控制系统基于重量数据T、轮廓数据中的长度数据L、数量修正因素X和长度修正因数Y，根据预设公式进行计算，得到切割冬瓜的单份目标长度L′，然后基于单份目标长度L′调整运输组件2和切割组件3的相对运动速度。
运输组件2将冬瓜向切割组件3方向运送，经过切割组件3时被刀具31切断，切割组件3能够将冬瓜切割成若干份长度为单份目标长度L′的成品，每份成品的重量为单份目标标准重量T′。
本公开的切割装置能够代替人工加工物料，能够将外形不规则的物料切割成重量均匀的成品，减轻了人力劳动，提高了工作效率，并且有效地减少了损耗量，提高了物料的成品率。
