参考图1-2，本申请第一种实施方式提出一种送料装置1，包括至少两个用于围设形成移动通道11的侧板12，可限制所述移动通道11内物料移动的限位单元13。当然，若侧板数量多于两个，则围设成的移动通道为多个，对应于多个移动通道设置多个限位单元13。
本申请提供的送料装置，通过限位单元设置，能够实现对于移动通道内出口或进口处物料间隔的控制，从而可以有效防止物料之间粘连的发生，同时，在料仓已满或需要短时间暂停时，通过限位单元限制移动通道内物料的移动，达到停止进料的目的，从而无需不断启动传送带，操作方便也不会影响设备使用寿命。
两个侧板12围设形成物料的移动通道11。所述侧板12包括侧板本体121，以及与所述侧板本体121铰接的活动件122，从而所述活动件122可以根据需要移动。活动件122作为移动通道11的出口，可根据送料需要相对侧板本体121转动，使移动通道11的出口与不同的料仓对接。
所述限位单元13用于限制所述移动通道11内物料的移动。所述限位单元13可选取气缸，气缸可向所述移动通道11内伸缩来拦截物料或通过将物料压在所述侧板12上来使物料停止移动。此处需要说明的是，所述限位单元并不限定为气缸，可采用其他形式，如以一定速度转动的半轮等结构，可以拦截所述移动通道内的物料移动即可。限位单元13固定在移动通道11外侧，包括可向移动通道11内伸缩的限位部131和与限位部131连接以驱动限位部131伸缩的第一驱动件132。具体地，限位单元13设于移动通道11外侧，可设于其中一个侧板12的外侧，或者两个侧板12外侧均设置限位单元13，以从移动通道11 两侧限制物料移动。为了缓冲限位单元与物料的碰撞，可在气缸的伸缩端与物料接触的部位连接接触部，接触部材质优选柔性材料，例如橡胶。所述限位单元13可设置在所述移动通道11的进口、出口或中间，可根据需要设置。
进一步的，所述送料装置1还包括用于检测物料通过的检测单元14，所述检测单元14可设于所述移动通道11的出口、进口或中间，可根据需要设置。所述检测单元可采用光电检测、超声检测、视频检测等检测方式，只要可以检测是否有物料通过即可，此处优选为使用光电检测。
进一步的，如图3所示，所述送料装置1还包括用于计数的计数单元15，所述计数单元15与所述检测单元14电性连接，用于统计检测单元14所检测到的物料数量，从而计算输入或输出的物料的数量。当检测单元14设于移动通道11的出口时，与其连接的计数单元15统计的是物料输出移动通道11的数量，当检测单元14设于移动通道11的进口时，与其连接的计数单元15统计的是物料输入移动通道11的数量。此外，若所述送料装置与料仓连接，在移动通道出口处设置检测单元和与检测单元电性连接的计数单元，此时所述计数单元还可与从料仓中抓取物料的抓料单元的计量单元电性连接，则计数单元可以计算出送料装置为料仓送料的数量和抓料单元从料仓中取走的物料数量，从而计算得出料仓内现有的物料的数量。可为料仓设定一个补料界限值和停料界限值，当料仓内现有物料的数量低于补料接限值时，送料装置继续为料仓送料，当料仓内现有物料的数量大于停料界限值时，送料装置停止为料仓送料。一般情况下只需要为料仓设置停料界限值，即，只有当该料仓的物料数量大于停料界限值时才暂停送料，以保证料仓中物料充足，避免抓料单元因为料仓供料不足停止工作，影响装料效率。
可选地，所述检测单元14设于所述移动通道11的出口和进口，与所述检测单元14连接的计数单元15从而可以计算出输入所述移动通道11内的物料数量，以及所述移动通道11输出的物料数量，从而可以计算出移动通道11内剩余的物料数量，根据移动通道11内剩余物料的数量控制移动通道11的进料。
进一步的，所述送料装置1还包括与两个所述侧板12连接的第一驱动单元16，所述第一驱动单元16可以驱动两个所述侧板12同步移动，从而可以实现所述移动通道11出口方向或进口方向的改变。当侧板12数量多于两个时，每两个形成移动通道11的侧板12与一个第一驱动单元16连接，以实现对每个移动通道11的单独控制。本实施方式中，所述第一驱动单元16与所述活动件122连接，所述第一驱动单元16驱动所述活动件122绕所述侧板本体121向同一侧旋转，从而使两个活动件122向同侧偏转，无需使整个侧板12移动而带动移动通道中的物料一起移动，即可迅速改变所述移动通道11的出口方向或进口方向。第一驱动单元可采用多种形式，如电缸或气缸，如仅需对两个料仓进行送料，则可使用气缸，如需对两个以上的料仓进行送料，此处可采用电缸，预设多个移动位置，可以对多个料仓送料。
进一步的，所述送料装置1还包括与两个所述侧板12连接的第二驱动单元17，所述第二驱动单元17用于驱动两个所述侧板12相向或相对移动，以控制两个所述侧板12之间的距离，从而调整所述移动通道11的宽度，用于适应不同尺寸的物料。当侧板12数量多于两个时，每两个形成移动通道11的侧板12均可相向或相背移动，以调节每个移动通道11的宽度。第二驱动单元优选为使用双螺纹丝杠的电缸，从而可以实现精确控制，此处丝杠可为滚珠或梯形丝杠，此外，也可使用手摇轮与丝杠的组合，成本低，也可手动调节。需要说明的是， 所述第二驱动单元17为两个，分别与侧板本体121和活动件122连接，两个第二驱动单元17可同步运动，也可分别控制，可根据需要设置。第二驱动件单元17设于所述第一驱动单元16下部，第一驱动单元16带动第二驱动单元17和侧板12同步移动。具体地，侧板本体121与第一连接部1211连接，第一连接部1211与第二驱动单元17连接，第一连接部1211带动侧板本体121在第二驱动单元17驱动下同步移动。活动件122与第二连接部1221连接，第二连接部1221与第二驱动单元17连接，第二驱动单元17安装在第一安装架123上，位于活动件122上方的第一驱动单元16与第一安装架123连接，从而带动第二驱动单元17和活动件122同步移动。
作为优选，两个侧板本体121与直线导轨124连接。具体地，在两个侧板本体121的外侧分别设有平行与侧板本体121的两个直线导轨124，侧板本体121通过第三连接部125与直线导轨124连接，第三连接部125可滑动的套设在直线导轨124上。第一连接部1211与直线导轨124相连，从而第二驱动单元17可带动侧板本体121移动。活动件122与侧板本体121夹角呈180度时，移动通道11为直线型，其可以为与活动件122对齐的料仓供料，当需要与切换料仓时，第一驱动单元16带动活动件122相对侧板本体121旋转一定角度，使得活动件122与预设料仓对接。侧板本体121在活动件122带动下沿着直线导轨124移动一段距离，两个侧板本体121的方向和间距保持不变。
如图3所示，送料装置1还包括控制器18，所述控制器18分别与所述限位单元13、第一驱动单元16、第二驱动单元17电性连接，可以控制所述限位单元13和所述第一驱动单元16按照预设的规则移动，从而限制所述移动通道11内的物料按照预设的规则停止运动，并控制所述第一驱动单元16按照预设的 规则使所述移动通道的活动件122移动至预设的位置。所述控制器18可连接存有预设程序的计算机可读介质，也可内置设定的计算机程序，或使用PLC编译的控制逻辑等。本实施方式中所述控制器18可控制所述限位单元13实现以下控制步骤：
可按照预设的时间间隔限制所述移动通道11内物料的移动，与所述移动通道11内物料的移动速度相匹配，可控制经过所述限位单元13的物料之间的间隔；
在所述计数单元15到达预设的数值时，即料仓已满，短时间内无需送料时，所述限位单元13限制所述移动通道11内的物料的移动，暂时停止送料；
如向多个料仓送料，在某一个料仓已满，另一个料仓未满时，所述第一驱动单元16驱动所述活动件122至预设位置，向未满料仓送料。
本申请提供的送料装置，通过限位单元和控制器的设置，能够实现对于移动通道内出口或进口处物料间隔的控制，从而可以有效防止物料之间粘连的发生，同时，在料仓已满或需要短时间暂停时，通过限位单元限制移动通道内物料的移动，达到停止物料运输的目的，从而无需不断启动传送带，操作方便也不会影响设备使用寿命。通过设置检测单元和计数单元，可以有效的实现准确计数。限位单元选用气缸，结构简单，成本低且易于控制。将与活动件连接的第一驱动单元与控制器电性连接，实现自动变道控制。通过活动件和侧板本体的结构设置，变道移动更加轻巧快捷。通过第二驱动单元的设置，可以调整两个侧板之间的宽度，可适应不同尺寸的物料。
本申请第二种实施方式提供一种包装机，包括如上所述的送料装置。
作为优选，所述包装机还包括与送料装置1对接的导向装置3，参考图4 至图7，所述导向装置3，包括多组侧板组件31，至少一组传动组件32，以及联动组件33。所述侧板组件31包括两个相对设置的第一供料侧板311和第二供料侧板312，所述传动组件32包括与所述第一供料侧板311连接的第一传动件321，以及与所述第二供料侧板312连接的第二传动件322，所述联动组件33分别与所述第一传动件321和所述第二传动件322连接。每组侧板组件31与一组传动组件32对应连接，即每组侧板组件的第一供料侧板311和第二供料侧板312分别与一组传动组件的第一传动件321和第二传动件322连接。
进一步的，所述第一传动件321和所述第二传动件322为两个平行设置的滚珠丝杠，两个所述滚珠丝杠的螺纹相反，即一个为左旋螺纹，另一个为右旋螺纹，从而可以通过控制两个所述滚珠丝杠的同向同速的转动，从而带动所述第一供料侧板311和所述第二供料侧板312相向或相背移动，实现所述第一供料侧板和所述第二供料侧板之间距离的快速调节。
具体地，所述联动组件33包括分别套设于所述第一传动件321和所述第二传动件322上的两个转动件，以及分别与两个所述转动件连接的同步件。具体地，所述联动组件33包括套设于所述第一传动件321上的第一转动件331，套设于所述第二传动件322上的第二转动件332，以及分别与所述第一转动件331和所述第二转动件332连接的第一同步件333。第一转动件331与第一传动件321同时转动，第二转动件332与第二传动件322同时转动，第一同步件333使第一转动件331和第二转动件332同步转动，从而第一传动件321和第二传动件322同步转动，带动第一供料侧板311和第二供料侧板312同步运动。
进一步的，所述导向装置3还包括与所述第一传动件321连接的第二驱动件34，通过所述第二驱动件34驱动所述第一传动件321，进而带动第二传动件 322转动，从而实现所述第一供料侧板311和所述第二供料侧板312之间的距离调整。当然，第二驱动件34也可以与第二传动件322连接。如图5和图7所示，第二驱动件可选取手摇轮或者电机。
进一步的，所述传动组件32为多组并且相互间隔设置，所述联动组件33与多组所述传动组件32连接以使多组所述传动组件32联动，多个所述传动组件32可同步运动。即，所述联动组件33还包括连接各个传动组件的第三转动件334和第四转动件335，以及分别与所述第三转动件334和所述第四转动件335连接的第二同步件336。本实施方式中，传动组件一共有三组，分别为第一传动组件、第二传动组件以及第三传动组件，分别设于侧板组件的三处不同位置。现在以第一传动组件和第二传动组件为例，说明两组传动组件联动的实现。第三转动件334和第四转动件335在第二同步件336带动下同时转动，第三转动件334与第一传动组件3201的第二传动件322同时转动，第四转动件335与第二传动组件的3202第一传动件321同时转动，从而使得第一传动组件3201和第二组传动组件3202同步转动。以此类推，可以实现多组传动组件32的联动，进而实现对侧板组件31的多个位置同时调节，从而实现侧板组件31的位置调节的同步和均匀性，满足物料移动和导向的需要。第一同步件333和第二同步件336均可采用同步带。多个所述传动组件间隔设置在述侧板组件的不同位置，例如进口、出口和中间位置。每组第一供料侧板311和第二供料侧板312可以形成一条供料通道35。传动组件32的位置根据所述供料通道35的长度进行调节，满足所述第一供料侧板311和第二供料侧板312的同步调节以及板材的受力条件即可。
本申请提供的包装机还包括抓料单元2，抓料单元2可从导向装置3中抓 取物料。
如图4至图7所示，本实施方式中侧板组件31一共形成三条供料通道35，分别为第一供料通道351、第二供料通道352和第三供料通道353。每组第一供料侧板311与第二供料侧板312形成的供料通道长度可以有所差异，如图6所示，第三供料通道353相比第一供料通道351，其长度较小，与第三供料通道353相连的传动组件32有两组，这是因为两组传动组件32已经满足第三供料通道353的宽度调节和移动的需要。另外，长度差异的供料通道35其取料位置也相互错开，可以方便抓料单元2从不同供料通道35的取料位置抓取物料料，避免抓料单元2相互干扰。
进一步的，所述供料通道出口端设置有限位件，所述限位件用于拦截供料通道中的物料，使物料停留在供料通道中，为抓料单元供料。若供料通道需要继续将物料转运，则可不用设置限位件。
导向装置与送料装置配合，可为多个供料通道进料，每个供料通道可同步且相互独立的为抓料单元供料。送料装置可以变道为不同供料通道进料，当其中一个供料通道暂时货满时，送料装置的限位单元限制移动通道内物料移动，第一驱动单元驱动活动件移动至预设位置，以变换移动通道出口使其与其他供料通道对接，从而为其他供料通道进料。导向装置为包装机的抓料单元提供多个供料通道，允许多组抓料单元同时抓取物料，提高了包装机的作业效率。
