下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
此外,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中,“多个”的含义是至少两个,例如两个,三个等,除非另有明确具体的限定。
在本申请中,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或成一体;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通或两个元件的相互作用关系,除非另有明确的限定。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本申请中的具体含义。
如图1及图2所示,本申请的一实施例中提供的一种自动换卷装置,包括安装架10、 放卷机构20、备料机构30及接带机构40。放卷机构20包括绕自身轴线可转动地连接于安装架10的放卷轴21。备料机构30包括备料轴32及推料件33(见图5)。备料轴32具有对接端320。备料轴32绕转动轴线可转动地连接于安装架10。推料件33用于为备料轴32上的备料卷提供轴向推力。备料轴32绕该转动轴线转动的过程中包括推料位置。当备料轴32处于推料位置时,备料轴32的对接端320与放卷轴21对接,推料件33受控推动备料轴32上的备料卷转移至放卷轴21。可以理解的是,由于要实现备料轴32旋转至推料位置,因此上述转动轴线与备料轴32的轴线不相互平行。优选地,转动轴线与备料轴32的轴线相垂直。
接带机构40设置于安装架10,用于将放卷轴21放出的工作料带切断,并将切断的工作料带连接于放卷轴21上的备料卷。
上述自动换卷装置,当放卷轴21上的工作料卷用完,需要更换料卷时,首先利用接带机构40将放卷轴21上放出的工作料带切断,卸下放卷轴21上的料筒(料卷包括料筒以及卷绕在料筒上的料带)。然后备料轴32绕转动轴线转动,使得备料轴32的对接端320与放卷轴21对接,接着推料件33推动备料轴32上的备料卷转移至放卷轴21上。最后,利用接带机构40将切断后的工作料带连接于放卷轴21上的备料卷,从而实现自动换卷。如此,与现有技术中需要配备互为备用的两套放卷机构的自动换卷装置相比,本申请的自动换卷装置利用备料轴32及推料件33,实现将备料轴32上的备料卷推送至放卷轴21,不需要配备两套放卷机构20,从而大大简化了自动换卷装置的结构,有利于减小占用空间。
需要说的是,推料件33为备料轴32上的备料卷提供轴向推力应该理解为:推料件33提供的推力可以是该推力本身平行于备料轴32的轴向,也可以是具有平行于备料轴32轴向的分力,只要能够实现将备料轴32上的备料卷推送至放卷轴21上即可,在此不作限定。
本申请的实施例中,放卷轴21沿自身轴向相对安装架10可移动。如此,可通过放卷轴21沿自身轴向移动来实现纠偏(即调整料带在其宽度方向上的位置)。
请一并参见图3及图4所示,本申请的实施例中,放卷机构20还包括第一导柱22、旋转轴23、第一驱动组件24及第二驱动组件25。第一导柱22沿自身轴线可移动地连接于安装架10。旋转轴23沿轴向固定且沿周向可转动地配接于第一导柱22内。也就是说,第一导柱22为中空柱,旋转轴23套设于第一导柱22内,旋转轴23可绕自身轴线相对第一导柱22转动,且在旋转轴23的轴向上相对第一导柱22固定。放卷轴21固定连接于旋 转轴23的一端,以使放卷轴21随旋转轴23同步转动,从而实现放卷。第一驱动组件24设置于安装架10,并与第一导柱22传动连接,使得第一驱动组件24驱动第一导柱22沿自身轴向相对安装架10移动,从而带动放卷轴21沿自身轴线移动。第二驱动组件25设置于第一导柱22,并与旋转轴23传动连接,使得第二驱动组件25驱动旋转轴23绕自身轴线旋转,从而带动放卷轴21旋转。如此,通过第一驱动组件24和第二驱动组件25分别实现驱动放卷轴21沿自身轴线移动且绕自身轴线转动运动,结构简单,运行稳定。并且,将旋转轴23套设于第一导柱22内有利于减小结构体积,减小占用空间。优选地,第一导柱22、旋转轴23及放卷轴21三者同轴设置。
具体到实施例中,旋转轴23可通过轴承安装于第一导柱22内,从而实现旋转轴23相对第一导柱22可转动,且在轴向方向上相对第一导柱22固定。
一些实施例中,放卷机构20还包括过辊组件26。该过辊组件26包括第二导柱261及过辊262。第二导柱261沿与第一导柱22相平行的方向可移动地连接于安装架10,且第二导柱261与第一导柱22可控地相互连接或分离。过辊262安装于第二导柱261,用于对放卷轴21放出的工作料带进行导向。如此,当需要对工作料带进行纠偏时,控制第二导柱261与第一导柱22连接,使得第二导柱261和第一导柱22同步移动,从而实现放卷轴21和过辊262同步地沿平行于放卷轴21的轴线方向移动,进而实现对料带宽度方向上的位置进行调整(即纠偏),如此避免了在纠偏过程中工作料带与过辊262产生在放卷轴21的轴向方向上的相对移动,从而对工作料带造成磨损的现象,有利于提高产品质量。当不需要纠偏时,控制第二导柱261与第一导柱22分离,从而防止第一导柱22沿自身轴线移动时(例如换卷和卸料时)带动第二导柱261和过辊262移动。
具体到实施例中,第一导柱22上固定连接有驱动部241。第二导柱261上固定连接有安装件263。过辊组件26还包括固定抱紧件264及活动抱紧件265。固定抱紧件264安装于安装件263,且抵接于驱动部241的一侧。活动抱紧件265可移动地连接于安装件263。活动抱紧件265在移动地过程中可与驱动部241的相对的另一侧相抵,从而利用固定抱紧件264和活动抱紧件265抱紧驱动部241,即实现了第二导柱261和第一导柱22的连接。当需要使得第二导柱261和第一导柱22分离时,可移动活动抱紧件265,使得活动抱紧件265和固定抱紧件264松开,与驱动部241分离。可选地,第二导柱261可包括相互平行的两根或两根以上,如此,一方面提高过辊262的移动稳定性,减小过辊262晃动;另一 方面能够起到防止第二导柱261转动的作用。
进一步地,过辊组件26还包括过辊安装板266,过辊安装板266固定连接于第二导柱261,过辊262安装于过辊安装板266。
具体到实施例中,过辊组件26还包括第一滑轨2630及第一驱动件267。第一滑轨2630固定连接于安装件263。活动抱紧件265设置于该第一滑轨2630,且沿第一滑轨2630可滑动。第一驱动件267固定连接于安装件263,且传动连接于活动抱紧件265,以驱动活动抱紧件265沿第一滑轨2630移动。如此,利用第一滑轨2630及第一驱动件267实现活动抱紧件265的移动,使得抱紧和松开动作稳定、可靠。可选地,第一驱动件267可为气缸。可以理解的是,第一驱动件267也可为其它能够实现直线往复运动的驱动件,在此不作限定。
进一步地,固定抱紧件264与活动抱紧件265分别位于驱动部241在与第一导柱22相垂直的方向上的两侧,从而防止当固定抱紧件264和活动抱紧件265松开驱动部241时对第一导柱22沿自身轴线的运动产生干涉。
进一步地,驱动部241朝向活动抱紧件265的一侧具有可与该活动抱紧件265相配合的配合槽。如此,进一步提高活动抱紧件265和固定抱紧件264对驱动部241抱紧时的稳定性。可选地,固定抱紧件264和活动抱紧件265均可为滚轮。当固定抱紧件264和活动抱紧件265松开时,固定抱紧件264可在驱动部241的表面滚动,减小摩擦。
一些实施例中,过辊组件26还包括锁定件268及锁定杆269。锁定件268固定连接于安装件263,锁定杆269固定连接于安装架10。锁定杆269与第二导柱261相平行,锁定件268可控地与锁定杆269连接或分离。如此,当不需要纠偏时,将第二导柱261与第一导柱22分离,此时为了防止过辊262移动,可使锁定件268与锁定杆269连接。当需要纠偏时,将锁定件268与锁定杆269分离,并将第二导柱261与第一导柱22连接,从而可使得第二导柱261和第一导柱22同步沿第一导柱22的轴向方向移动,即过辊262和放卷轴21同步沿放卷轴21的轴向移动,进而实现纠偏。可选地,锁定件268可为夹爪气缸。
一些实施例中,第一驱动组件24包括第一丝杆242、第一丝杆螺母243及滑动件244。第一丝杆242一端可绕自身轴线转动地连接于安装架10,且与第一导柱22相平行。第一丝杆螺母243螺纹连接于第一丝杆242。滑动件244固定连接于第一导柱22和第一丝杆螺母243。如此,通过第一丝杆242的转动驱动第一丝杆螺母243沿第一丝杆242移动,从 而带动滑动件244和第一导柱22沿第一导柱22的轴向方向移动,进而带动放卷轴21沿自身轴线移动。进一步地,驱动部241固定连接于滑动件244。
具体到实施例中,第一驱动组件24还包括第三导柱245、第一安装座246及丝杆驱动件247。第三导柱245的一端固定连接于安装架10,且与第一导柱22相平行。第一安装座246固定连接于第三导柱245的另一端。丝杆驱动件247安装于第一安装座246,且与第一丝杆242远离安装架10的一端传动连接,以使丝杆驱动件247驱动第一丝杆242绕自身轴线转动。进一步地,滑动件244设置于第三导柱245,且沿第三导柱245可滑动,从而对滑动件244进行导向,使得滑动件244的移动更加稳定。具体地,丝杆驱动件247可为电机。
可选地,丝杆驱动件247的输出轴可通过联轴器传动连接于第一丝杆242。
为了使各个滑动部件的移动更加稳定,可选地,滑动件244可通过导套可滑动地安装于第三导柱245。第一导柱22也可通过导套可滑动地安装于安装架10。第二导柱261也可通过导套可滑动地安装于安装架10。
一些实施例中,第二驱动组件25包括第二安装座251、旋转驱动件252及传动结构。第二安装座251固定连接于第一导柱22。旋转驱动件252安装于第二安装座251。传动结构传动连接于旋转驱动件252与旋转轴23之间,以由旋转驱动件252驱动旋转轴23绕自身轴线旋转,从而带动放卷轴21绕自身轴线旋转。具体到实施例中,第二安装座251固定连接于滑动件244上。
具体到实施例中,传动结构包括相互啮合的主动齿轮253和从动齿轮254。主动齿轮253安装于旋转驱动件252的输出轴,以使主动齿轮253和旋转驱动件252的输出轴同步转动。从动齿轮254安装于旋转轴23,以使从动齿轮254与旋转轴23同步转动。如此,通过相互啮合的主动齿轮253和从动齿轮254将旋转驱动件252输出的旋转运动传递至旋转轴23,从而驱动旋转轴23旋转。需要说明的是,传动结构并不仅限于采用齿轮传动结构,也可采用例如带传动等结构,在此不作限定。可选地,旋转驱动件可为电机。
需要说明的是,放卷轴21和过辊262位于安装架10的同一侧,以使放卷轴21放出的料带通过过辊262导向。第一导柱22和第二导柱261贯穿安装架10的相对两侧,第三导柱245位于安装架10背离放卷轴21的一侧。
本申请的实施例中,备料机构30还包括抵推件34(见图1)。备料轴32还具有相对 对接端320的抵推端322。抵推件34固定连接于抵推端322。备料轴32绕上述转动轴线转动地过程中还包括备料位置。当备料轴32处于备料位置时,抵推件34朝向放卷轴21,用于抵推放卷轴21上的备料卷。如此,推料件33将备料轴32上的备料卷推送至放卷轴21上之后,放卷轴21沿其轴线向远离备料轴32的方向移动,备料轴32绕转动轴线转动至备料位置,以使抵推件34朝向放卷轴21。然后放卷轴21沿其轴线向靠近备料轴32的方向移动,抵推件34紧抵于放卷轴21上的备料卷,从而使得备料卷与放卷轴21产生沿放卷轴21的轴线产生相对移动,以对备料卷在放卷轴21上的位置进行调整(即定位)。可选地,抵推件34包括固定连接于抵推端322的本体及围绕本体布设的多个推爪。每一推爪均向本体背离抵推端322的一侧延伸,用于与放卷轴21上的备料卷接触,进而对备料卷进行抵推。如此,避免放卷轴21与抵推件34接触。
需要说明的是,为了防止对备料轴32绕转动轴线转动至备料位置的过程中,放卷轴21及放卷轴21上的备料卷对抵推件34的运动产生干涉,因此,在将备料轴32转动至备料位置之前,放卷轴21需要沿其轴线向远离备料轴32的方向移动,从而有效避位。当备料轴32转动至备料位置后,放卷轴21沿其轴线向靠近备料轴32的方向移动,同时利用抵推件对放卷轴21上的备料卷进行抵推,从而实现备料卷在放卷轴21上的定位。
具体到实施例中,放卷轴21上设置有定位块27。如此,在抵推件34抵推放卷轴21上的备料卷直至抵靠在定位块27上实现定位,即实现了将备料卷抵推到位。
需要说明的是,备料卷在放卷轴21上的定位并不仅限于采用在备料轴32上安装抵推件的方式,在另一些实施例中,也可设计独立的抵推机构。请参见图8所示,抵推机构包括抵推轴52及抵推件53,抵推轴52绕自身轴线可转动地连接于安装架10。抵推件53安装于抵推轴52。在抵推轴52绕自身轴线转动地过程中,抵推件53包括抵推位置。当抵推件53位于抵推位置时,抵推件53位于放卷轴21与备料轴32之间,用于抵推放卷轴21上的备料卷。
如此,当推料件33将备料轴32上的备料卷推送至放卷轴21上后,放卷轴21沿自身轴线向远离备料轴32的方向移动,抵推机构的抵推轴52转动从而带动抵推件53处于抵推位置,此时抵推件53位于放卷轴21和备料轴32之间。然后,放卷轴21沿自身轴线向靠近备料轴32的一端移动,从而使得抵推件53紧抵放卷轴21上的备料卷,进而将备料卷抵推到位。最后,抵推轴52转动带动抵推件53转动至初始位置,放卷轴21沿自身轴 线移动至工作位置。
具体到实施例中,抵推机构包括第三安装座54及抵推驱动件55。第三安装座54固定安装于安装架10。抵推轴52绕自身轴线可转动地连接于第三安装座54。抵推驱动件55设置于第三安装座54,且传动连接于抵推轴52,以驱动抵推轴52绕自身轴线转动。
进一步地,抵推驱动件55可为气缸。抵推机构还包括驱动块57及铰接座56。驱动块57固定连接于抵推轴52,铰接座56固定连接于第三安装座54。抵推驱动件55的固定端铰接连接于铰接座56,且铰接轴线与抵推轴52的轴线相平行。抵推驱动件55的驱动端铰接连接于驱动块57,且铰接轴线与抵推轴52的轴线相平行且不共线。如此,通过抵推驱动件55的驱动端伸缩,从而驱动抵推轴52绕自身轴线转动,从而带动抵推件53摆动。
进一步地,抵推机构还包括旋转支撑座57,旋转支撑座57固定连接于第三安装座54。抵推轴52穿设于旋转支撑座57,且可相对旋转支撑座57转动。具体地,抵推轴52通过轴承安装于旋转支撑座57。
具体到实施例中,抵推机构还包括调节块58、调节杆59及第一弹性件591。调节块58固定连接于抵推轴52,抵推件53沿抵推轴52的轴线可移动地安装于抵推轴52的一端。调节杆59的一端贯穿调节块58,并连接于抵推件53。第一弹性件591设置于调节块58远离抵推件53的一侧,且第一弹性件591的一端抵接于调节杆59,相对的另一端抵接于调节块58,以提供使抵推件53具有沿抵推轴52的轴线向调节块58移动趋势的预紧力。可选地,第一弹性件591可为压缩弹簧。该压缩弹簧套设于调节杆59,且位于调节块58远离抵推件53的一侧。可选地,调节杆59为螺杆,螺杆螺纹连接于抵推件53。
如此,当抵推件53处于抵推位置(即放卷轴21和备料轴32之间)时,放卷轴21沿自身轴线朝向备料轴32移动,放卷轴21上的备料卷接触抵推件53,从而压缩第一弹性件591进行缓冲,并使得抵推件53抵接备料轴32实现支撑。放卷轴21沿自身轴线朝向备料轴32继续移动时,抵推件53推动放卷轴21上的备料卷相对放卷轴21移动,使其到达工作位置。
进一步地,抵推机构还包括导杆592。该导杆592穿设于调节块58,并相对调节块58可滑动,且导杆592的一端固定连接于抵推件53。如此,导杆592可对抵推件53沿抵推轴52的轴线滑动进行导向。可以理解的是,导杆592平行于抵推轴52。
请一并参见图5、图6及图7,本申请的实施例中,备料轴32为空心轴。备料轴32 的周向侧壁开设有至少一条滑槽321。该滑槽321沿备料轴32的轴向纵长延伸。推料件33沿备料轴32的轴向可滑动地设置于备料轴32内,且由对应的滑槽321伸出至备料轴32外。如此,备料卷套装于备料轴32上,推料件33沿滑槽321滑动时,推料件33伸出滑槽321的部分推动备料卷沿备料轴32移动,直至将备料轴32推送至放卷轴21上。
一些实施例中,备料机构30还包括推料驱动组件,推料驱动组件包括推料丝杆361、推料丝杆螺母35及推料驱动件36。推料丝杆361设置于备料轴32内,且相对备料轴32可旋转。推料丝杆螺母35螺纹连接于推料丝杆361。推料件33与推料丝杆螺母35相对固定设置。推料驱动件36安装于备料轴32的一端,且与推料丝杆361传动连接,以驱动推料丝杆361转动。如此,当需要将备料轴32上的备料卷推送至放卷轴21上时,推料驱动件36驱动推料丝杆361旋转,从而带动推料丝杆螺母35沿推料丝杆361移动,进而带动推料件33沿推料丝杆361移动(即沿备料轴32的轴向移动)。可以理解的是,推料丝杆361与备料轴32的轴向相互平行。优选地,推料丝杆361同轴设置于备料轴32内。
具体到实施例中,推料驱动组件还包括相互啮合的主动锥齿轮362和从动锥齿轮364。主动锥齿轮362安装于推料驱动件36的输出轴,从动锥齿轮364安装于推料丝杆361的一端。如此,通过相互啮合的主动锥齿轮362和从动锥齿轮364实现了推料驱动件36和推料丝杆361之间的传动。可选到,推料驱动件36可为电机。
具体到实施例中,推料驱动组件还包括固定套设于推料丝杆螺母35外的驱动轮37。推料件33固定连接于驱动轮37。
为了对驱动轮37进行导向,在一个实施例中,推料驱动组件还包括固定安装于备料轴32内的推料导向杆,该推料导向杆平行于备料轴32的轴线,且贯穿驱动轮37,驱动轮37可沿推料导向杆滑动。如此,推料导向杆用于对驱动轮37的移动进行导向,使得推料件33的移动更加稳定,推料动作稳定可靠。需要说明的是,在另一个实施例中,也可不设置推料导向杆,而是通过备料轴32的内壁对驱动轮37的移动进行导向。也就是说,驱动轮37与备料轴32的周向内壁滑动配合,以使驱动轮37可沿备料轴32的周向内壁滑动,从而实现对驱动件37的移动进行导向。
具体到实施例中,推料驱动组件还包括安装于驱动轮37的导向滚轮,该导向滚轮滚动配合于滑槽321内,以沿滑槽321滚动,从而对驱动轮37及推料件33沿备料轴32的轴向移动进行导向,使得推料件33推料更加稳定。由于设置了导向滚轮进行导向,因此 推料件33可仅通过滑槽321穿出至备料轴32外,而不与滑槽321的内壁接触而进行导向,从而避免了推料件33与滑槽321的内壁接触而产生磨损。
更加具体地,备料轴32上开设有两条滑槽321,每个滑槽321对应设置一个推料件33。如此,设置两个推料件33分别沿两条滑槽321移动,使得推料件33推料更加稳定。两条滑槽321位于备料轴32的底部。
具体到实施例中,备料机构30还包括第一传感器391。备料轴32的周侧开设有检测口。第一传感器391安装于检测口,用于检测驱动轮37的位置。如此,可通过第一传感器391对驱动轮37的位置的检测,以对驱动轮37的运动范围进行限定,防止驱动轮37碰撞备料轴32两端的部件。可以理解的是,驱动轮37设置有与第一传感器391对应的感应块。
具体到实施例中,备料轴32沿其轴向具有至少一个用于供备料卷套设的备料位。每一备料位均设置有第二传感器。该第二传感器用于检测对应的备料位是否套设有备料卷。如此,通过第二传感器392可检测备料轴32上的各个备料位是否有备料卷。
优选地,第一传感器391包括两个,检测口也包括两个,两个检测口沿备料轴32的轴向间隔布设,两个第一传感器391分别安装于两个检测口内。为了避免第二传感器392影响备料轴32装载备料卷,可在备料轴32的周测开设检测凹槽,该检测凹槽连通两个检测口。多个第二传感器392设置于检测凹槽内。进一步地,备料机构30还包括盖板393,盖板393盖设于检测凹槽,用于防止第二传感器392脱落。盖板393对应于第二传感器392的位置开设有检测缺口。第二传感器392通过对应的检测缺口检测备料卷。

具体到实施例中,备料轴32的周向侧壁上设置有耐磨条326。耐磨条326沿备料轴32的轴向纵长延伸。耐磨条326用于防止备料卷在备料轴32上频繁移动时造成备料轴32的磨损。进一步地,备料轴32的周向侧壁上开设有用于安装耐磨条326的安装凹槽。耐磨条326部分凸出于备料轴32的周侧表面。
具体到实施例中,备料轴32的对接端320的周向外表面开设有涨紧槽,备料机构还包括设置于所述涨紧槽内的涨紧组件327。该涨紧组件327可受控的沿备料轴32的径向移动,从而伸出或缩回涨紧槽。当涨紧组件327沿备料轴32的径向移动而伸出涨紧槽时,涨紧组件327涨紧套设于对接端320的备料卷,此时该备料卷相对备料轴32固定,即备料卷不能沿备料轴32的轴向移动,防止了备料轴32旋转过程中在离心力的作用下将备料卷甩出。当涨紧组件327沿备料轴32的径向移动,从而缩回涨紧槽时,涨紧组件327对套设于对接端320的备料卷的涨紧解除,备料卷可沿备料轴32的轴向移动,以便于进行换卷。
进一步地,涨紧组件327包括涨紧块及膨胀件。涨紧块设置于备料轴32涨紧槽,且涨紧块可沿备料轴32的径向移动而伸出或缩回该涨紧槽。膨胀件设置于涨紧槽底壁和涨紧块之间。该膨胀件可受控的膨胀或收缩,以驱动涨紧块沿备料轴32的径向移动。可选地,膨胀件可为气囊。当需要固定备料卷时,对气囊充气,可以使得涨紧块沿着备料轴32的径向向外移动,涨紧块伸出涨紧槽,从而将备料卷相对备料轴32固定。当不需要固定备料卷时,对气囊放气,可以使得涨紧块沿着备料轴32的径向向内移动,涨紧块缩回涨紧槽内,从而将备料卷松开。
具体到实施例中,备料机构30还包括分别固定安装于备料轴32的对接端320和抵推端322的第一端盖324和第二端盖325。推料丝杆361的相对两端分别通过轴承可转动地连接于第一端盖324和第二端盖325。

进一步地,备料传动组件包括备料主动轮314、备料从动轮315、备料传动带316及备料旋转轴317。旋转支架312通过备料旋转轴317绕转动轴线可转动地连接于安装支架311。备料主动轮314安装于备料驱动件313的输出轴,以与备料驱动件313的输出轴同步 转动。备料从动轮315安装于备料旋转轴317,以与备料旋转轴317同步转动。备料传动带316套设于备料主动轮314与备料从动轮315之间,以使备料主动轮314和备料从动轮315同步转动。需要说明的是,备料传动组件并不仅限于采用上述带传动的方式,在其它实施例中也可采用例如齿轮传动的方式,在此不作限定。可选地,备料驱动件313可为电机。
请一并参见图1及图9所示,本申请的实施例中,自动换卷装置还包括废料收集机构60,用于卸下放卷轴21上的料筒。在将备料轴32上的备料卷推送至放卷轴21上之前,需要将放卷轴21上的料筒卸下,废料收集机构60即用于卸下放卷轴21上的料筒。
废料收集机构60包括绕第一轴线可转动地连接于安装架10上的抓取组件62。抓取组件62在绕该第一轴线转动地过程中包括抓取位置和放料位置。当抓取组件62处于抓取位置时,抓取组件62用于抓取放卷轴21上的料筒;当抓取组件62处于放料位置时,抓取组件62释放料筒。如此,当放卷轴21上的工作料卷快用完时,利用接带机构40将放卷轴21上放出的工作料带切断。然后将抓取组件62绕第一轴线转动至抓取位置,并对放卷轴21上的料筒进行抓取。再然后,放卷轴21沿轴线移动,从而使得料筒与放卷轴21分离。随后,抓取组件62绕第一轴线转动至放料位置,即将与放卷轴21分离的料筒转移至放料位置并释放。也就是说,实现了自动卸下废料,避免了采用人工卸料,降低了人工成本,提高了生产效率。
一些实施例中,抓取组件62包括转动轴621、第二驱动件622、第一摆臂623及抓手624。转动轴621绕自身轴线可转动地连接于安装架10。可以理解的是,转动轴621的轴线即为上述第一轴线。第二驱动件622设置于安装架10,且传动连接于转动轴621,以驱动转动轴621绕自身轴线转动。第一摆臂623的一端固定连接于转动轴621,抓手624设置于第一摆臂623的另一端。如此,当第二驱动件622驱动转动轴621转动,带动抓手624至抓取位置时,抓手624抓取放卷轴21上的料筒,即料筒相对抓手624固定。然后放卷轴21沿其轴线移动,使得料筒于放卷轴21分离。再然后第二驱动件622驱动转动轴621转动,带动抓手624至放料位置,此时,抓手624释放料筒,从而实现放卷轴21上料筒的卸载。可选地,抓手624可为夹爪气缸。

进一步地,第一摆臂623的一侧具有导轨6232,第一滑块625设置于该导轨6232,且可沿导轨6232滑动。第一摆臂623相对的另一侧设置有第三驱动件626。也就是说,第一滑块625和第三驱动件626分别位于第一摆臂623的相对两侧。如此,使得抓手624的移动更加平稳、可靠。
具体到实施例中,第二驱动件622的输出轴可通过联轴器传动连接于转动轴621。可选地,第二驱动件622可为电机。更加具体地,第二驱动件622可通过固定座固定安装于安装架10,以保证第二驱动件622的连接稳定性,减弱第二驱动件622的振动。
一些实施例中,废料收集机构60还包括存储组件64。存储组件64位于抓取组件62的下方。存储组件64包括滑座641。滑座641具有沿第一方向间隔布设的多个用于存放料筒的储料区域(多个储料区域中的“多个”应该理解为两个或两个以上)。滑座642沿第一方向可滑动地连接于安装架10,以带动多个储料区域顺序地移动至放料位置的下方,便于承接由抓手624释放的料筒。如此,抓取组件62在放料位置释放料筒,使得料筒落入储料区域内。并且当一个储料区域存满料筒后,滑座641沿第一方向移动,使得另一储料区域移动至放料位置的下方。
优选地,第一方向与第一轴线相平行。如此,有利于减小废料收集机构60在垂直于第一轴线方向上所占用的体积。
具体到实施例中,存储组件64还包括第二丝杆及第四驱动件643。第二丝杆绕自身轴线可转动地连接于安装架10。滑座641螺纹连接于第二丝杆。第四驱动件643设置于安装架10,且传动连接于第二丝杆,以驱动第二丝杆绕自身轴线转动。如此,第四驱动件643驱动第二丝杆转动,从而使得滑座641沿第二丝杆的轴线方向移动,进而实现将多个储料区域顺序地移动至放料位置的下方。可以理解的是,第二丝杆的轴线平行于上述第一方向。更加具体地,存储组件64还包括第二丝杆螺母。第二丝杆螺母螺纹连接于第二丝杆。滑座641固定连接于第二丝杆螺母。也就是说,滑座641通过第二丝杆螺母间接地螺纹连接于第二丝杆。
进一步地,存储组件64还包括导向杆644。导向杆644的一端固定连接于安装架10。且与第二丝杆相平行。滑座641可滑动地连接于导向杆644。如此,通过导向杆644对滑座641的滑动进行导向,使得滑座641的移动更加稳定、可靠。
可选地,第四驱动件643可为电机。第四驱动件643的输出轴可通过联轴器传动连接于第二丝杆。
具体到实施例中,存储组件64还包括两个支撑杆645。两个支撑杆645固定连接于滑座641。该两个支撑杆645间隔布设且均平行于第一方向。两个支撑杆645之间形成用于承载料筒的储料空间。该储料空间包括沿第一方向布设的多个储料区域。如此,可从两个支撑杆645上方将料筒放置于储料空间内的储料区域,使得两个支撑杆645对料筒进行承载而实现存储。当需要卸下料筒时,只需将料筒向上提起即可与支撑杆645分离。需要说明的是,为了实现对料筒进行承载,两个支撑杆645之间的间距小于料筒的直径。
进一步地,存储组件64还包括多个分隔件646。多个分隔件646固定连接于两个支撑杆645,且沿支撑杆645的纵长方向间隔布设,以将多个储料区域分隔开来(即每相邻两个储料区域之间设置一分隔件646)。也就是说,多个分隔件646将储料空间沿支撑杆645的纵长方向分隔为多个储料区域,每个储料区域用于存储一个料筒。如此,分隔件646的设置有效避免了位于相邻两个储料区域内的两个料筒之间相互影响。
请一并参见图10、图11及图12,本申请的第一实施例中,接带机构40包括第二摆臂41、第一夹持组件42及第一切刀43。第二摆臂41的一端绕第二轴线可转动地连接于安装架10,第一夹持组件42绕第三轴线可转动地连接于第二摆臂41的另一端,第一夹持组件42用于夹持工作料带,第一切刀43设置于第二摆臂41,且可朝向第一夹持组件42靠近或远离,第一切刀43用于切断该料带。如此,当需要换卷时,接带机构40的第一夹持组件42将放卷轴21上放出的工作料带夹紧。然后第一切刀朝向第一夹持组件42靠近而切断被夹紧的工作料带。再然后废料收集机构60卸下放卷轴21上的料筒,推料件33将备料轴32上的备料卷推送至放卷轴21上,并对放卷轴21上的备料卷进行定位。第一夹持组件42绕第三轴线转动使得切断后的工作料带部分包裹在第一夹持组件42外侧。最后,第二摆臂41转动使得第一夹持组件42夹持的工作料带靠近放卷轴21上的备料卷,以将工作料带粘贴于放卷轴21上的备料卷。
优选地,第二轴线与放卷轴21的轴线相平行。第三轴线与第二轴线相平行。
一些实施例中,第一夹持组件42包括第一转盘421、固定夹辊422及活动夹辊423。第一转盘421绕第三轴线可转动地连接于第二摆臂41的一端。固定夹辊422安装于第一转盘421,活动夹辊423可朝向固定夹辊422靠近或远离地连接于第一转盘421。如此,通过活动夹辊423的朝向固定夹辊422靠近或远离来实现对工作料带的夹紧或松开。也就是说,当需要对工作料带进行夹持时,活动夹辊423朝向靠近固定夹辊422的方向移动,从而夹紧位于活动夹辊423和固定夹辊422之间的工作料带。当将工作料带连接于备料卷之后,需要松开工作料带时,活动夹辊423朝向远离固定夹辊422的方向移动,从而松开工作料带。并且,在将工作料带粘贴于备料卷时,第一转盘421转动从而使得切断的工作料带部分包裹于固定夹辊422或活动夹辊423并朝向备料卷,以便于粘贴。需要说明的是,为了更好的对放卷轴21放出的工作料带进行夹持,活动夹辊423和固定夹辊422均平行于第二轴线,即平行于放卷轴21。
具体到实施例中,固定夹辊422和活动夹辊423其中之一可绕自身轴线可转动。也就是说,当固定夹辊422与活动夹辊423夹紧工作料带,在一定的外力拉动工作料带时,可带动固定夹辊422或活动夹辊423绕自身轴线转动。如此,第二摆臂41转动使得活动夹辊423和固定夹辊422夹紧的工作料带靠近放卷轴21上的备料卷,直至包裹有工作料带的固定夹辊422或活动辊423抵压于备料卷上,以使工作料带粘贴于备料卷。然后备料卷随放卷轴21转动,从而通过工作料带带动固定夹辊422或活动辊423绕自身轴线转动,以将工作料带的尾端完全粘贴于备料卷,避免出现由于工作料带尾部部分未粘贴于备料卷而形成自由端,在走带过程中容易抖动而掉粉,从而影响产品质量的现象。优选地,固定夹辊422可绕自身轴线可转动。如此,在将工作料带粘贴于备料卷之前,第一转盘421转动从而使得切断的工作料带部分包裹于固定夹辊422上,并朝向备料卷。
具体到实施例中,第一夹持组件42还包括设置于第一转盘421的第五驱动件424。该第五驱动件424传动连接于活动夹辊423,以驱动活动夹辊423朝向固定夹辊422靠近或远离。更加具体地,活动夹辊423通过活动夹辊座安装于第五驱动件424的驱动端。可选地,第五驱动件424可为夹爪气缸。
具体到实施例中,固定夹辊422也可通过固定夹辊座固定连接于第一转盘421,从而固定夹辊422的连接更加稳固。
进一步地,第一夹持组件42还包括设置于活动夹辊座与固定夹辊座之间的第二弹性 件,该第二弹性件用于提供使得活动夹辊座具有朝向固定夹辊座远离的运动趋势的预紧力。如此,第二弹性件的设置,一方面起到缓冲作用,避免活动夹辊423和固定夹辊422夹持工作料带时对工作料带造成刚性冲击而损坏工作料带。另一方面,第五驱动件424驱动活动夹辊423并与固定夹辊422配合而夹紧工作料带,同时压缩第二弹性件。当需要松开工作料带时第五驱动件424卸力,在第二弹性件的作用下活动夹辊423朝向固定夹辊422远离,从而松开工作料带。由此,第五驱动件424可采用单气路夹爪气缸,从而减少了气路,减小气路缠绕的风险。

进一步地,第一固定架44上具有第二滑轨441,第二滑块45滑设于第二滑轨441上。也就是说,第二滑块45可沿第二滑轨441滑动。

进一步地,上述第一传动轴491可为空心轴。该第一传动轴491同轴套设于第一摆轴47外侧,且相对第一摆轴47可转动。如此,将第一传动轴491与第一摆轴47套设,使得结构更加紧凑,有利于简化结构,减小占用空间。可选地,第一传动轴491可通过轴承同轴安装于第一摆轴47外侧。
具体到一个实施例中,第一接带机构40还包括第一滑动板451及第一轴安装座452。第一滑动板451固定连接于第二滑块45。第七驱动件48固定安装于第一滑动板451上。第一轴安装座452固定连接于第一滑动板451。第一摆轴47绕自身轴线可转动地连接于第一轴安装座452。第一传动轴491套设于第一摆轴47外侧。第八驱动件49固定安装于第一轴安装座452上。可选地,第二滑块45可包括两个或两个以上,从而进一步提高接带机构40动作的稳定性。

需要说明的是,本申请的自动换卷装置并不仅限于采用上述实施例中的接带机构40实现将工作料带切断并粘贴至备料卷上。请一并参见图12、图13及图14,本申请的第二实施例中,接带机构40’包括移动件41’、用于夹持工作料带的第二夹持组件42’及用于切断工作料带的第二切刀43’。移动件41’朝靠近或远离备料卷可移动地设置于安装架10。第二夹持组件42’绕第三轴线可转动地连接于移动件41’。如此,当在换卷的过程中需要将工作料带粘贴于备料卷时,接带机构40’的第二夹持组件42’将工作料带夹紧。第二切刀43’将工作料带切断。第二夹持组件42’绕第三轴线转动使得部分工作料带包裹于第二夹持组件42’的外侧,移动件41’带动第二夹持组件42’朝向放卷轴21上的备料卷靠近,以将工作料带粘贴于放卷轴21上备料卷。
在本实施例中,第二夹持组件42’包括第二转盘421’、至少两个第一夹辊422’以及夹板423’。第二转盘421’绕上述第三轴线可转动地连接于移动件41’。每一第一夹辊422’均设置于第二转盘421’,夹板423’设置于第二转盘421’。
其中,该至少两个第一夹辊422’与夹板423’中至少一者可在外力作用下相当另一者靠近或远离,以在该至少两个第一夹辊422’与夹板423’之间形成用于夹持工作料带的夹持位。也就是说,夹板423’可朝向该至少两个第一夹辊422’靠近或远离;或者,夹板423’固定连接于第二转盘421’,该至少两个第一夹辊422’可朝向夹板423’靠近或远离。或者,该至少两个第一夹辊422’和夹板423’均可移动而相互靠近或远离。
第二切刀43’设置于移动件41’,且可由任意相邻两个第一夹辊422’之间切入或退出夹持位。当需要切断工作料带时,第二切刀43’由相邻两个第一夹辊422’之间切入夹持位,从而将被夹持于夹持位的工作料带切断,然后第二切刀43’由该相邻两个第一夹辊422’之间退出夹持位而恢复至初始位置。
上述接带机构40’,利用至少两个第一夹辊422’与夹板423’之间形成用于对工作料带进行夹持的夹持位,且第二切刀43’由任意两个第一夹辊422’之间切入该夹持位,从而将夹持于该夹持位的工作料带切断。与现有技术中切刀切断工作料带时只有切刀一侧的工作料带被压紧相比,本实施例中由于第二切刀43’切断工作料带时,第二切刀43’两侧均有第一夹辊422’将工作料带压紧于夹板423’,从而有效避免了出现切断面撕烂的情况,减小了毛刺,切断效果好,有利于提高产品质量。
具体到实施例中,夹板423’朝向上述至少两个第一夹辊422’的一侧具有一夹持面,各个第一夹辊422’沿夹持面间隔布设,且相互平行。
更加具体地,第二夹持组件42’包括两个第一夹辊422’,两个第一夹辊422’之间形成供第二切刀43’通过的切刀通道。夹持面上开设有对应切刀通道的避让槽d’。如此,第二切刀43’可由切刀通道切入夹持位直至避让槽d’,从而将工作料带切断。避让槽d’的设置一方面确保切断工作料带;另一方面,避免第二切刀43’与夹板423’接触,从而损坏夹板423’和第二切刀43’。
需要说明的是,在一个实施例中,第二切刀43’移动的过程中包括切断位置,当第二切刀43’处于切断位置时,第二切刀43’由切刀通道切入避让槽d’内。如此,当第二切刀43’由切刀通道切入避让槽d’内到达切断位置时,夹持面上的工作料带被切断。
具体到实施例中,每一第一夹辊422’均可绕自身轴线可转动地连接于第二转盘421’。如此,通过夹板423’和上述至少两个第一夹辊422’相互靠近或远离来实现对工作料带的夹紧或松开。在将工作料带粘贴于备料卷时,第二转盘421’转动从而使得工作料带部分包裹在外侧的一个第一夹辊422’上,并朝向备料轴32上的备料卷。移动件41’移动使得该包裹有工作料带的第一夹辊422’抵压在备料卷上,从而将工作料带粘贴于备料卷上。由于第一夹辊422’可绕自身轴线转动,因此可在第一夹辊422’抵压在备料卷上时放卷轴21带动备料卷转动,从而通过工作料带带动第一夹辊422’滚动,进而将工作料带的整个尾端均粘贴于备料卷,避免了出现工作带料的尾端留有一小段不能粘贴于备用料卷 上尾巴的现象出现,有利于提高产品质量。
需要说明的是,采用第二切刀43’由相邻两个第一夹辊422’之间切入夹持位而切断工作料带的方式,工作料带的尾端长度较短(即工作料带的切断面至被第一夹辊422’和夹板423’夹持的位置的长度),有利于简化将工作料带的整个尾端均粘贴于备料卷的操作,即简化了粘贴动作,提高粘贴动作的可靠性。
具体到实施例中,移动件41’为摆臂,移动件41’的一端绕第二轴线可转动连接于安装架10,第二转盘421’绕上述第三轴线可转动地连接于移动件41’的另一端。其中,移动件41’绕第二轴线转动的过程中,夹持组件42’可靠近或远离放卷轴21上的备料卷。如此,通过移动件41’绕第二轴线的转动来实现第二夹持组件42’靠近或远离放卷轴21上的备料卷,有利于接带过程稳定可靠,且节省占用空间。
优选地,第二轴线与放卷轴21的轴线相平行。第三轴线与第二轴线相平行。需要说明的是,为了更好的对放卷轴21放出的工作料带进行夹持,每一第一夹辊422’均平行于第二轴线,即平行于放卷轴21。
还需要说明的是,为了实现带动第二夹持组件42’可靠近或远离备料卷,并不仅限于采用如上述实施例中的摆臂摆动的形式。在其他实施例中,也可采用移动件沿直线或曲线移动的方式来实现,在此不作限定。
在一个实施例中,第二夹持组件42’还包括设置于第二转盘421’的第九驱动件424’。该第九驱动件424’传动连接于夹板423’,以驱动夹板423’朝向各个第一夹辊422’靠近或远离。即夹板423’相对第二转盘421’移动,而各个第一夹辊422’不相对第二转盘421’移动。更加具体地,夹板423’通过夹板座安装于第九驱动件424’的驱动端。各个第一夹辊422’均通过第四安装座425’安装于第二转盘421’。
在另一个实施例中,第二夹持组件42’还包括第四安装座425’及第九驱动件424’,各个第一夹辊422’均安装于第四安装座425’,第四安装座425’设置于第二转盘421’。第九驱动件424’设置于第二转盘421’,且传动连接于第四安装座425’,以驱动安装有第一夹辊422’的第四安装座425’朝向夹板423’靠近或远离。即第四安装座425’及安装于第四安装座425’上的各个第一夹辊422’相对第二转盘421移动,而夹板423’不相对第二转盘421’移动。
在又一个实施例中,各个第一夹辊422’均安装于第四安装座425’,第四安装座425’ 设置于第二转盘421’,第九驱动件424’包括两个,两个第九驱动件424’设置于第二转盘421’,且分别传动连接于夹板423’和第四安装座425’,以分别驱动夹板423’和安装有第一夹辊422’的第四安装座425’相对运动而相互靠近或远离。即安装有第一夹辊422’的第四安装座425’和夹板423’均相对第二转盘421’移动。
可选地,第九驱动件424’可为夹爪气缸。
一些实施例中,第二夹持组件42’还包括第三弹性件426’,第一夹辊422’设置于第四安装座425’,第四安装座425’设置于第二转盘421’。第三弹性件426’设置于第四安装座425’与夹板423’之间,以提供使第四安装座425’及夹板423’具有朝向彼此背离的方向移动趋势的弹力。如此,在第一夹辊422’和夹板423’相互靠近而对工作料带进行夹持时,第三弹性件426’的设置起到缓冲作用,避免第一夹辊422’和夹板423’之间产生硬冲击。还需要说明的是,第九驱动件424’驱动第四安装座425’和夹板423’相互靠近,使得夹板423’和至少两个第一夹辊422’夹持工作料带,同时压缩第三弹性件426’。当需要松开工作料带时第九驱动件424’卸力,在第三弹性件426’的作用下第四安装座425’和夹板423’相互远离,从而松开工作料带。由此,第九驱动件424’可采用单气路夹爪气缸,从而减少了气路,减小气路缠绕的风险。
具体到实施例中,接带机构40’还包括第二固定架44’、第三滑块45’及第十驱动件46’。第二固定架44’固定连接于安装架10。第三滑块45’沿与第二轴线相平行的方向可移动地连接于第二固定架44’。移动件41’远离第二夹持组件42’的一端绕第二轴线可转动地连接于第三滑块45’。第十驱动件46’安装于第二固定架44’,且传动连接于第三滑块45’,以驱动第三滑块45’沿与第二轴线相平行的方向移动。如此,当需要对放卷轴21放出的工作料带夹紧时,第十驱动件46’驱动第三滑块45’沿平行于第二轴线的方向(即平行于放卷轴21的方向)移动,从而带动第二夹持组件42’的第一夹辊422’和夹板423’沿平行于第二轴线的方向移动,以便工作料带插入第一夹辊422’和夹板423’之间。然后第一夹辊423和夹板423’相互靠近,以实现对位于夹板423’和第一夹辊422’之间的工作料带的夹紧。可选地,第十驱动件46’可为平移气缸。
进一步地,第二固定架44’上具有第三滑轨441’,第三滑块45’滑设于第三滑轨441’上。也就是说,第三滑块45’可沿第三滑轨441’滑动。

进一步地,上述第二传动轴491’可为空心轴。该第二传动轴491’同轴套设于第二摆轴47’外侧,且相对第二摆轴47’可转动。如此,将第二传动轴491’与第二摆轴47’套设,使得结构更加紧凑,有利于简化结构,减小占用空间。可选地,第二传动轴491’可通过轴承同轴安装于第二摆轴47’外侧。

支撑座71固定连接于安装架10,且具有用于供第一导柱22穿设的轴孔。由于支撑座 71相对安装架10固定,第一导柱22相对安装架10沿自身轴线可移动,因此第一导柱22相对支撑座71沿自身轴线可移动。旋转轮72绕轴孔的轴线可转动地连接于该支撑座71。导向驱动件73设置于安装架10,且传动连接于旋转轮72,以驱动该旋转轮72绕轴孔的轴线旋转。旋转臂76一端固定连接于旋转轮72,导向辊77设置于旋转臂76的另一端。如此,导向驱动件73可驱动旋转轮72旋转,从而带动旋转臂76及导向辊77随旋转轮72转动,进而可调节导向辊77的位置,以对工作料带导向。与现有技术中导向辊77沿直线运动相比,由于本实施例中通过旋转结构安装导向辊77,且支撑座71可通过轴孔套设于第一导柱22,使得结构紧凑,减小占用空间,使用更加灵活。
具体到实施例中,轴孔的轴线与放卷轴21的轴线共线,使得导向辊77位置调节更加灵活,且进一步减小占用空间。进一步地,导向辊77的轴线与轴孔的轴线相平行,即导向辊77与放卷轴21相平行,从而能够更好的对放卷轴21放出的料带进行导向。

请参见图18所示,基于上述自动换卷装置,本申请还提供一种换卷方法。如下以自动换卷装置采用第一实施例中的接带机构40为例进行说,换卷方法包括步骤:
S100:利用接带机构40将放卷轴21放出的工作料带切断,然后卸下放卷轴21上的料筒。
具体地,第六驱动件46驱动第二滑块45沿与第二轴线相平行的方向(即与放卷轴21的轴线相平行的方向)移动,使得工作料带插入固定夹辊和活动夹辊之间。然后第五驱动件驱动活动夹辊朝向固定夹辊移动,从而夹紧工作料带。再然后,第一裁切驱动件431驱动第一切刀切断工作料带。
第二驱动件622驱动转动轴621转动,带动抓手624至抓取位置,抓手624抓取放卷轴21上的料筒,即料筒相对抓手624固定。然后放卷轴21沿其轴线移动,使得料筒与放卷轴21分离。再然后第二驱动件622驱动转动轴621转动,带动抓手624至放料位置,此时,抓手624释放料筒,料筒落入储料区域内而被收集。
进一步地,为了方便工作料带插入固定夹辊和活动夹辊之间,可通过导向组件的旋转轮72旋转,从而利用导向辊77调整工作料带的位置,使得工作料带与固定夹辊和活动夹辊之间的缝隙对齐。
S200:转动备料轴32使得备料轴32的对接端320与放卷轴21对接。然后推料件33将备料轴32上的备料卷推送至放卷轴21。
具体地,转动备料轴32,使得备料轴32的对接端320朝向放卷轴21。然后驱动放卷轴21沿自身轴线朝向对接端320移动,以使放卷轴21与对接端320接触而对接。备料轴32上的推料件33沿备料轴32移动,从而将备料轴32上的备料卷推送至放卷轴21上。

具体地,第八驱动件49驱动第一转盘421旋转,使得工作料带的部分包裹在固定夹辊422或活动夹辊423上。
第七驱动件48驱动第二摆臂41绕第一摆轴47转动,使得上述包裹有部分工作料带的固定夹辊422或活动夹辊423与放卷轴21上的备料卷相接触,从而将工作料带粘接于备料卷(为便于料带的连接,备料卷的备料料带的起头端具有双面胶,利用该双面胶与工作料带粘接)。放卷轴21转动,从而带动放卷轴21上的备料卷转动,进而通过工作料带带动固定夹辊422或活动夹辊423绕自身轴线转动,使得工作料带的整个尾部均粘贴于备料卷上。然后,第五驱动件驱动活动夹辊背离固定夹辊移动,从而松开工作料带。
第六驱动件46驱动第二滑块45沿与第二轴线相平行的方向移动,第七驱动件48驱动第二摆臂41绕摆轴47转动,使得接带机构40回到原位。
进一步地,为了避免接带机构40回到原位的过程中带动工作料带,可利用导向组件的导向辊77挑起工作料带,使得工作料带与接带机构40分离。当接带机构40回到原位之后,导向组件的导向辊77带动工作料带至合适位置进行放卷。
一些实施例中,在步骤S200之后还包括步骤S201:将放卷轴21上的备料卷沿放卷轴21的轴线抵推到位。
具体到一个实施例中,步骤S201具体包括:放卷轴21沿自身轴线向远离备料轴32的方向移动,备料轴32转动使得备料轴32上的抵推件53朝向放卷轴21。放卷轴21沿自身轴线向靠近备料轴32的方向移动,以使抵推件53将放卷轴21上的备料卷抵推到位(即备料卷接触定位块27)。可以理解的是,放卷轴21沿自身轴线向远离备料轴32的方向移动是为了避位,防止备料轴32转动使得备料轴32上的抵推件53朝向放卷轴21时对抵推件53产生干涉。
在另一个实施例中,步骤S201具体包括:放卷轴21沿自身轴线向远离备料轴32的方向移动。抵推机构的抵推轴52绕自身轴线转动,以带动抵推件53转动至抵推位置,即抵推件53位于备料轴32与放卷轴21之间。放卷轴21沿自身轴线向靠近备料轴32的方向移动,以使抵推件53将放卷轴21上的备料卷抵推到位(即备料卷接触定位块27)。
需要说明的时,当备料轴32的对接端320背离放卷轴21时,备料轴32的对接端320可与例如AGV等上料装置对接,以便将一个或多个备料卷装载于备料轴32上。
