为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
目前一次性卫生用品生产过程中使用的翻转机构，由于翻转前后产品组的位移较大，不仅导致包装设备进行转产换码步骤繁琐，并且导致包装机的设计成增加，同时会降低产品的包装速率，提高企业的生产成本以及管理成本，不能满足高速产品生产线的需要。
为解决现有的翻转机构翻转前后产品组的位移较大的问题，本发明提供一种翻转机构，参见图1～图10所示，该翻转机构包括翻转机架1、翻转盒装置2、翻转驱动装置3以及曲杆组件4；其中，翻转机架1用于对翻转盒装置2、翻转驱动装置3以及曲杆组件4进行支撑固定，该翻转机架1可以固定在包装机的机 架上；翻转盒装置2用于对待包装的一次性产品进行翻转换向；翻转盒装置2与翻转驱动装置3分别设置于翻转机架1的两端；翻转驱动装置3通过曲杆组件4与翻转盒装置2相连，翻转驱动装置3通过曲杆组件4来带动翻转盒装置2进行翻转换向，以实现对放置于翻转盒装置2中的待包装产品的翻转换向。
本申请中的翻转盒装置2包括翻转盒底座21，以及与翻转盒底座21转动连接的翻转盒22，其中翻转盒22用于盛放待包装的产品，翻转盒底座21与翻转机架1滑动连接；翻转盒底座21与翻转机架1可以通过相适配的滑槽与滑块来实现滑动连接；本申请优选翻转机架1上固定连接有翻转盒导轨副11，翻转盒底座21与翻转盒导轨副11上的滑块相连，以实现翻转盒底座21与翻转机架1的滑动连接；进一步的，本申请优选在翻转机架1上还设置有翻转盒导轨垫块12，翻转盒导轨副11通过该翻转盒导轨垫块12与翻转机架1固定连接。
本申请中的曲杆组件4包括摆杆41、翻转连杆42以及移动连杆43；其中摆杆41的第一端与翻转驱动装置3相连，第二端与翻转连杆42以及移动连杆43转动连接；同时，翻转连杆43上远离摆杆41的一端与翻转盒22转动连接；移动连杆43上远离摆杆41的一端与翻转盒底座21转动连接。
该翻转机构工作过程中，参见图1～图3所示，翻转盒22位于初始状态，通过推杆5将排列整齐的待包装产品6推入翻转盒22中，在驱动装置3驱动下，摆杆41逆时针摆动；在摆杆41的带动下，移动连杆43向左推动翻转盒底座21水平移动，同时带动位于翻转盒底座21上方的翻转盒22向左水平移动；并且，翻转连杆42带动翻转盒22与翻转盒底座21发生顺时针方向的相对转动，即，在翻转驱动装置3以及曲杆组件4的带动下，翻转盒22发生向左水平移动，同时顺时针旋转的复合运动；当翻转盒22顺时针旋转90°后停止，通过与翻转盒22相适配的推手7将翻转盒22内进行90°翻转换向后的待包装产品6推出，翻转驱动装置3驱动摆杆41顺时针方向摆动，在摆杆41的带动下，移动连杆43向右拉动翻转盒底座21水平移动，同时带动位于翻转盒底座21上方的翻转盒22向右水平移动；并且，翻转连杆42带动翻转盒22与翻转盒底座21发生逆时针方向的相对转动，即，在翻转驱动装置3以及曲杆组件4的带动下，翻转盒装置2复位，等待下一次翻转。
由于翻转盒22发生顺时针方向旋转的同时，会产生向右的位移；本申请通 过翻转连杆42以及移动连杆43的协同作用，使得翻转盒22发生向左水平移动，同时顺时针旋转的复合运动，从而可以通过向左水平运动来抵消顺时针旋转过程中产生的向右的位移，实现翻转盒22的原位90°翻转，进而实现待包装产品6的原位90°旋转。
本发明提供的翻转机构，在翻转驱动装置3与驱动组件4的带动下，使得翻转盒22能够实现原位90°旋转，从而避免翻转机构翻转前后产品组发生位移，使得该翻转机构与包装设备的衔接更加方便，有利于降低包装设备的设计成本，提高包装速率，降低企业的生产成本及管理成本，使得该翻转机构能够匹配高速生产线的运行。
本申请优选翻转驱动装置3包括相连的驱动电机31以及减速机32，减速机32的输出端与摆杆41相连，以便于通过驱动电机31与减速机32来驱动摆杆41顺时针或逆时针旋转，进而实现翻转盒22的原位翻转。
参见图4、图5所示，本申请中的翻转盒底座21包括底板211；该底板211与翻转机架1滑动连接，具体的，本申请优选底板211与翻转盒导轨副11上的滑块相连；进一步的，底板211上连接有支座2111，以及与支座2111转动连接的移动销轴2112；移动连杆43与移动销轴2112转动连接，从而使得移动连杆43能够通过该移动销轴2112来带动翻转盒底座21沿水平方向移动。
本申请中的翻转盒底座21还包括分别垂直连接于底板211两端的第一侧板212与第二侧板213；其中第一侧板212以及第二侧板213仅用于对两个侧板进行区分，并不构成对侧板位置的限定；翻转盒22包括翻转盒本体221，与翻转盒本体221相连的摆臂组件222，以及支轴223；其中翻转盒本体221通过四个板状结构依次首尾相连构成，该翻转盒本体221的两端均设置有开口结构，以便于通过两端的开口结构来对待包装产品6进行取放；四块板状结构围合构成用于放置待包装产品的容纳腔；该翻转盒本体221的具体结构及尺寸可根据待包装产品6进行确定；并且，为避免通过推手7将翻转盒本体221内的待包装产品6推出时与翻转盒本体221发生干涉，本申请优选翻转盒本体221的上端面上设置有避让槽；摆臂组件222通过支轴223与第一侧板212以及第二侧板213转动连接，即，支轴223位于第一侧板212与第二侧板213之间，支轴223的两端分别与第一侧板212以及第二侧板213相连，同时摆臂组件222与支轴223转动连接； 且摆臂组件222上远离翻转盒本体221的一端与翻转连杆42转动连接，从而使得摆臂组件222的一端与翻转盒本体221相连，另一端与翻转连杆42相连，支轴223位于翻转盒本体221与翻转连杆42之间。
在驱动装置3驱动下，摆杆41逆时针摆动时，在摆杆41的带动下，移动连杆43向左推动翻转盒底座21水平移动，使得翻转盒装置2整体向左水平移动；翻转连杆42推动摆臂组件222上远离翻转盒本体221的一端向左移动，使得摆臂组件222绕支轴223顺时针方向转动，从而使得与摆臂组件222相连的翻转盒本体221绕支轴223顺时针方向旋转，翻转盒22与翻转盒底座21发生顺时针方向的相对转动，进而在翻转驱动装置3以及曲杆组件4的带动下，翻转盒本体221发生向左水平移动，同时顺时针旋转的复合运动，实现翻转盒本体221的原位90°翻转；相反，当翻转盒本体221顺时针旋转90°后停止，通过翻转驱动装置3驱动摆杆41顺时针方向摆动，移动连杆43向右拉动翻转盒底座21水平移动，使得翻转盒装置2整体向右水平移动；翻转连杆42拉动摆臂组件222上远离翻转盒本体221的一端向右移动，使得摆臂组件222绕支轴223逆时针方向转动，从而使得与摆臂组件222相连的翻转盒本体221绕支轴223逆时针方向旋转，进而在翻转驱动装置3以及曲杆组件4的带动下，翻转盒本体221发生向右水平移动，同时逆时针旋转的复合运动，实现翻转盒本体221的复位，等待下一次翻转。
进一步的，本申请中第二侧板213的上端连接有挡板214，以便于在翻转盒本体221处于初始位置，未进行翻转前，参见图1所示，挡板214位于翻转盒本体221的末端，即远离推杆5的一端，待包装产品6通过推杆5被推入翻转盒本体221中的容纳腔中时，在挡板214的阻挡作用下，保证待包装产品不会被推出容纳腔的外侧；当翻转盒本体221进行翻转后，参见图2所示，翻转盒本体221远离挡板214，从而使得容纳腔内的待包装产品能够顺利被推出。
通过在第二侧板213的上端设置挡板214，结构简单；在将待包装产品6推入翻转盒本体221中时，能够避免待包装产品6溢出；同时，该挡板214的设置又不会影响在翻转后将待包装产品6从翻转盒本体221中推出。
本申请中的摆臂组件222包括摆臂2221、支臂2222以及翻转销轴2223；本申请优选摆臂组件222设置于第一侧板212与第二侧板213之间；其中摆臂组件 222通过支臂2222与翻转盒本体221相连；摆臂2221与支臂2222固定连接，并且摆臂2221与支臂2222中的至少一个与支轴223转动连接；本申请优选摆臂2221与支轴223转动连接；进一步的，为便于翻转盒本体221进行翻转，本申请优选摆臂2221与支臂2222之间设置有一夹角；摆臂2221通过翻转销轴2223与翻转连杆42转动连接，从而在翻转连杆42移动时，能够带动翻转盒本体221绕支轴223进行转动。
本申请提供的翻转机构中，翻转盒22还包括压缩组件224，以便于能够在翻转过程中通过该压缩组件对待包装产品6进行压缩；该压缩组件224包括压缩板2241、导板2242以及导向柱2243；压缩板2241位于翻转盒本体221内，支臂2222与压缩板2241固定连接，且支臂2222与翻转盒本体221滑动连接；本申请优选翻转盒本体221的底板上设置有与支臂2222相适配的安装孔，支臂2222穿过该安装孔与压缩板2241相连；导板2242的一端与翻转盒本体221固定连接，另一端通过导向柱2243与第一侧板212转动连接；导向柱2243与支轴223沿竖直方向分布，且导向柱2243位于支轴223的下方。
参见图6所示，翻转盒本体221未进行翻转前，放置于翻转盒本体221容纳腔中的待包装产品6处于未压缩状态，厚度为W1；摆杆41逆时针摆动时，在摆杆41的带动下，翻转连杆42推动摆臂2221向左移动，使得支臂2222绕支轴223顺时针方向转动，从而使得与支臂2222相连的压缩板2241绕支轴223沿顺时针方向转动；同时，翻转盒本体221沿顺时针方向移动；由于翻转盒本体221与导板2242相连，导板2242又通过导向柱2243与第一侧板212转动连接，因此，翻转盒本体221绕导向柱2243沿顺时针方向旋转；又由于导向柱2243与支轴223沿竖直方向分布，且导向柱2243位于支轴223的下方，导向柱2243相对于支轴223固定，因此，翻转过程中，迫使翻转盒本体221相对于压缩板2241发生向下的位移，参见图7所示，使得翻转盒本体221内容纳腔的容积减小，待包装产品6被压缩；翻转盒本体221翻转90°后，待包装产品6的厚度被压缩至W2，即翻转后待压缩产品6的厚度减小了△W＝W1-W2，实现了在翻转过程中对待压缩产品6进行压缩，从而将翻转工序与压缩工序合为一个工序进行，有助于减少包装步骤，简化包装工序，提高包装效率，降低包装成本。
为提高结构的稳定性，本申请优选压缩组件224还包括压缩导轨副2244， 该压缩轨道副2244沿竖直方向分布，压缩导轨副2244与支臂2222固定连接，且导板2242以及翻转盒本体221均与压缩导轨副2244的滑块固定连接。
在翻转过程中，一方面，在支臂2222的带动下，压缩板2241绕支轴223沿顺时针方向转动，同时，连接于支臂2222上的压缩导轨副2244同步沿顺时针方向转动；另一方面，又由于导板2242以及翻转盒本体221均与压缩导轨副2244的滑块固定连接，因此，翻转盒本体221在导板2242以及压缩导轨副2244的共同作用下，绕导向柱2243进行顺时针旋转，同时又与滑块一起，与支臂2222发生相对移动；并且在翻转盒本体221旋转90°后，通过压缩导轨副2244的滑块来对翻转盒本体221在竖直方向上的位置进行限定；本申请优选翻转盒本体221旋转90°后，压缩导轨副2244的滑块滑至最低点时，导板2242沿水平方向分布，压缩板2241与翻转盒本体221的底板分离，翻转盒本体221内容纳腔的高度减小，压缩板2241对待包装产品6进行压缩。
进一步的，本申请优选导板2242上设置有与导向柱2243相适配的导向槽2245，导向柱2243嵌于导向槽2245内；并进一步优选导向槽2245为长形槽。
进一步的，为扩大翻转机构的使用范围，便于转产换码，本申请优选压缩组件224还包括第一调整螺杆2246以及挡块2247，挡块2247与第一侧板212相连，第一调整螺杆2246的上端通过螺纹与导向柱2243相连，第一调整螺杆2246的下端与挡块2247转动连接，以便于通过旋转第一调整螺杆2246来对导向柱2243的高度进行调节，进而对导板2242以及翻转盒本体221翻转后的高度进行调节，实现对翻转后翻转盒本体221内容纳腔高度的调节；其中翻转后容纳腔高度的减小值即为上文所述的待包装产品6的厚度减小值△W＝W1-W2，该△W为支轴223与导向柱2243之间的竖直距离；当将导向柱2243调节至与支轴223同轴，即高度相同时，容纳腔高度的减小值为0，即翻转过程中对待包装产品6无压缩。
本申请中翻转盒本体221以及压缩板2241的型号可以根据生产需要进行换码；通过设置第一调整螺杆2246来对导向柱2243的高度进行调节，使得换码后翻转盒本体221相对于压缩板2241的位置，也就是翻转盒本体221中容纳腔的高度可以根据需要进行调整，从而有助于进行转产换码，扩大翻转机构的使用范围。
本申请优选进行翻转前后，放置于翻转盒本体221内的待包装产品6的底面高度保持不变，以便于更利于翻转机构与包装机上的前后通道进行衔接，在进行转产换码时更加方便。
本申请优选压缩板2241为空腔结构，且压缩板2241的上表面设置有气孔，从而能够通过向压缩板2241的空腔中接入压缩空气，压缩空气通过气孔吹向位于压缩板2241上的待包装产品6，使得压缩板2241上表面与待包装产品6之间的摩擦力减小，进而降低将被压缩的待包装产品6从翻转盒本体221中推出的难度。
为进一步扩大该翻转机构的使用范围，本申请进一步优选翻转驱动装置3与翻转机架1滑动连接，具体的，本申请优选翻转机架1上设置有驱动导轨垫块13，以及安装于驱动导轨垫块13上的驱动调整导轨副14；翻转驱动装置3还包括减速机固定板33，减速机固定板33安装于驱动调整导轨副14上；具体的，驱动导轨垫块13的侧面安装有丝杆挡块15，该丝杆挡块15上安装有丝杆16；减速机固定板33上安装有螺母板331，该螺母板331通过螺纹与丝杆16相连，以便于通过该丝杆16来调节翻转驱动装置3以及翻转盒装置2水平方向上的位置，进而根据使用需求将翻转盒装置2调节至需要的位置；减速机32安装于减速机固定板33的外侧，并且减速机33的输出端与摆杆41固定连接。
本申请进一步优选摆杆41的第二端设置有滑槽，滑槽内设置有滑块411，滑块411通过第二调整螺杆412与摆杆41螺纹连接；翻转连杆42以及移动连杆43均与滑块412转动连接；具体的，本申请优选滑块411的两端各设置有一转轴，两个转轴均与减速机32的输出轴平行设置，位于上方的转轴与翻转连杆42转动连接，位于下方的转轴与移动连杆43转动连接；通过第二调整螺杆412来调节滑块411于滑槽411内的位置，进而实现对翻转连杆42以及移动连杆43位置的调节；当滑块411离减速机32的输出轴越近，翻转过程中产生的水平位移量越小，反之越大。
譬如，参见图8所示，翻转盒本体221中容纳腔在翻转前竖直中心面为A，翻转后竖直中心面为B，若A面与B面能够始终重合，则当容纳腔与包装机上前后通道进行衔接时，AB面与前后通道的竖直中心面也重合，即所有通道中心面相同；进行转产换码后，需要重新调整容纳腔进行翻转前后的位 置，以使其满足上述要求；本申请提供的翻转机构，通过丝杆16与第二调整螺杆412共同调节，即可满足上述需求，使得翻转机构与包装机上前后通道实现无缝衔接。
本发明提供的翻转机构，通过推杆5将包装机内整齐排列的产品组，即待包装产品6推入翻转盒本体221内，翻转盒本体221在翻转驱动装置3的驱动下，通过曲杆组件4带动进行水平移动，同时自身进行90°翻转；实现待包装产品6的原位翻转；再通过推手7将翻转后的待包装产品6从翻转盒本体221内推出，推出的待包装产品6进入下一工序，同时翻转盒本体221在翻转驱动装置3以及曲杆组件4作用下，返回原位，等待下一次翻转；该翻转机构通过对待包装产品6进行原位翻转，有利于简化包装设备进行转产换码的步骤，并使翻转机构与包装机上前后通道实现无缝衔接。
本申请中的翻转机构，可以应用于单通道包装机，也可以应用于双通道包装机；当应用于双通道包装机上时，可有采用两组翻转机构对称布置的方案。
当转产至不翻转包装形式时，首先使本申请提供的翻转机构始终保持翻转后的状态，然后更换所需的翻转盒本体221及压缩板2241，调整前后通道的宽度，调整翻转盒本体221位置，使容纳腔与前后通道一一对应。工作时，待包装产品6被推杆5推入翻转盒本体221内，然后，压缩板2241空腔内接通压缩空气，推手7将待包装产品6推出翻转盒本体221，此过程中翻转盒本体221仅作为过渡通道的作用。
虽然本公开披露如上，但本公开的保护范围并非仅限于此。本领域技术人员，在不脱离本公开的精神和范围的前提下，可进行各种变更与修改，这些变更与修改均将落入本发明的保护范围。
