Description

一种瓶盖铝圈分拣系统 技术领域
本发明涉及瓶盖生产加工领域，主要涉及一种瓶盖铝圈分拣系统。
 背景技术
随着自动化生产的发展，各行各业都在由原来人工装配发展为自动化生产线装配，瓶盖生产厂家也不例外，逐步由人工装配、检测替换成现在自动化成型、装配、检测，其大大提高了工作效率，降低了人工劳动成本，提高了公司的生产效益，瓶盖是食品与饮包装重要的一环，也是消费者最先与产品接触的地方。瓶盖具有保持内容物产品密闭性能，还具有防盗开启及安全性方面的功能，因此广泛的应用在瓶装产品上，所以瓶盖为食品，饮业，酒，化工业，制药业的上游产业，是瓶容器包装之关键性产品。瓶盖的发展早期是使用软木材质，马口铁皇冠盖及旋开盖，至今续开发出铝质的长颈铝盖，碳酸饮铝盖，热充填铝盖，注射液铝盖，药盖，掀开式环盖，安全钮爪盖及塑胶瓶盖等产品。
其材质和结构各不相同，也有根据需要进行结合的方式，本申请是针对铝塑分体式瓶盖结构中的铝圈的结构在进行装配过程中如何实现自动化装配的，铝圈在整个瓶盖是实现压紧固定瓶盖内塞的结构，因为其结构是薄薄的铝圈的结构，其材质比较软，容易变形，而且比较小，采用现有结构中传统的分拣系统，其虽然可以实现分拣的目的，但铝圈在分拣过程中由于大量的铝圈在分拣盘内堆积，容易变形，而且在分拣过程中只能实现铝圈的逐个平齐摆放，无法对铝圈的上端口和下端口进行筛选调整，因此在装配时，还需要人工对其方向进行分辨，然后再套装到生产线上的内塞上。
因此需要对传统的分拣系统进行改进，使其能够保证铝圈在下料分拣过程中不变形，且能够对变形的铝圈进行及时的剔除，能够对铝圈的上端口和下端口进行统一筛选调整，满足装配时铝圈上端口朝上，同时保证取料装配时保证铝圈不变形。
 技术问题
本申请是针对铝塑分体式瓶盖结构中的铝圈的结构在进行装配过程中如何实现自动化装配的，铝圈在整个瓶盖是实现压紧固定瓶盖内塞的结构，因为其结构是薄薄的铝圈的结构，其材质比较软，容易变形，而且比较小，采用现有结构中传统的分拣系统，其虽然可以实现分拣的目的，但铝圈在分拣过程中由于大量的铝圈在分拣盘内堆积，容易变形，而且在分拣过程中只能实现铝圈的逐个平齐摆放，无法对铝圈的上端口和下端口进行筛选调整，因此在装配时，还需要人工对其方向进行分辨，然后再套装到生产线上的内塞上。
因此需要对传统的分拣系统进行改进，使其能够保证铝圈在下料分拣过程中不变形，且能够对变形的铝圈进行及时的剔除，能够对铝圈的上端口和下端口进行统一筛选调整，满足装配时铝圈上端口朝上，同时保证取料装配时保证铝圈不变形。

所述的铝圈输出导向轨道由多段槽体组成，其包括有进料段，中间过渡段和出料段，所述进料段的槽体的截面为U形结构，且U形槽的宽度略大于铝圈的高度，其进料端与筛选模板的出料端对接且略低于筛选模板的出料端，从而保证从筛选模板出料端进入到铝圈输出导向轨道的进料段时铝圈呈竖向结构，所述中间过渡段为L形板体结构，其L形板体的底端面为倾斜向外设置的板体，所述L形板体的进料端上方架设有沿其长度方向设置的挡条，所述挡条从进料至出料方向上略倾斜向下设置，且出料端的挡条距离L型板体底端面的距离略大于铝圈的高度，所述出料段为横向设置的U型槽体，且U型槽体的内侧边设有与其长度方向配合的限位挡边，所述U型槽体的进料端与中间过渡段L形板体的底端面对接，所述U型槽体的进料端与铝圈出料轨道对接。
所述的铝圈出料轨道包括有槽体，所述槽体的出料端设有方便取料的弹性限位组件，所述槽体的底端面下方设有气腔，所述槽体的底端面上分布有间隔设置的出气口，所述出气口与气腔连通，所述气腔的进气口通过鼓风机，所述槽体的正上方设有高度可调的压条，所述压条的两端分别通过螺杆固定在槽体一侧的固定耳上，所述固定耳上开设有U形槽，所述螺杆的固定端穿过U形槽且通过锁紧螺纹固定安装在固定耳上。
所述的弹性限位组件包括有限位挡块，所述限位挡块上开设有用于容纳出料端端部铝圈的卡槽，所述限位挡块的底端卡装在固定座上，所述限位挡块的底端设有导柱，所述固定座上分布有与导柱导向配合的导向孔，所述限位挡块与固定座之间的导柱上套装有弹簧，所述导柱的底端套装有限位块，所述限位挡块的上端面的卡槽的外侧开设有方便取料卡爪动作的台阶面。
所述的气动夹紧式取料组件包括有架设在铝圈出料轨道正上方的固定梁，所述固定梁上导向安装有水平移动的滑座，所述滑座的移动通过水平移动气缸驱动，所述滑座的底端安装有活塞杆伸出端竖直向下设置的升降气缸，所述升降气缸的活塞杆伸出端安装有夹持固定座，所述夹持固定座的底端部安装有导向座，所述导向座的中部设有两对称设置的锥形槽，所述锥形槽内分别安装有锥形导块，所述锥形导块的上端分别铰接有驱动杆，所述驱动杆的上端部均铰接在取放气缸的活塞杆伸出端，所述夹持固定座上开设有供驱动杆活动的空腔，所述锥形导块的底端面分别固定安装有夹持块，所述夹持块的夹持端面上分别设有用于卡装铝圈的半圆形卡槽，所述半圆形卡槽内壁设有固定有橡胶层。
其原理是：通过分拣盘上方的储料箱结构，一方面可将大量的备料铝圈放置到静置的储料箱内进行储放，而分拣盘的供料则通过间隙抖动式投料的出料槽，进行间断式的出料，出料掉落至分拣盘上即可实现少量的铝圈产品随着分拣盘的转动进行有规律的分拣，分拣时，产品在分拣盘转动的离心力的作用下，铝圈进入到圆形围挡内壁的导向轨道，随着转动的进行，铝圈不断的进入，从而推动前面的铝圈沿着导向轨道和圆形围挡内壁螺旋导向移动，直至移动到最上方的导向轨道处，即完成了对落料的铝圈进行逐步分拣排列。
从导向轨道输出的铝圈虽然均是水平排列的，但由于铝圈比较软因此在落料或者分拣过程中有可能会出现变形的情况，变形的铝圈肯定是不合格品，因此需要对其进行剔除，并列铝圈的上端口和下端口的结构不同，因此需要对其端面朝向进行调整，本申请中通过筛选模板，首先通过弧形漏料开口一对变形的铝圈进行剔除，通过弧形漏料开口二以及两侧的弧形限位挡板一和弧形限位挡板二结构的配合，对水平输送过来的上端面向上的铝盖进行剔除，下端口朝上的铝圈则继续导出，从而保证了合格切开口朝向统一的铝圈进行到铝圈输出导向轨道上。
通过铝圈输出导向轨道的结构，可对从筛选模板出来的铝圈进行调整方向，使其上端口朝向上方，从而满足铝圈装配时的朝向的要求，其具体过程时，首先通过进料段的槽体的结构，将输出的下端口朝向的铝圈进行竖向排列，先竖向输送，然后进入到中间过渡段，配合挡条的结构，可对其竖向排列的铝圈进行限位，使其朝向挡条的另一侧进行翻转，且挡条出料端和中间过渡段的板体之间构成导向通道，从而使得输出的铝圈均是上端口朝上，之后再通过出料端的U型槽体和限位挡边通过的输送通道进行导向，从而保证铝圈的输出。
对铝圈进行调整方向之后进入到铝圈出料轨道上，沿着铝圈出料轨道进行整体的排列，然后再通过出料端的气动夹紧式取料组件进行夹取放置到装配线上，从而满足自动化取料装配的要求。
 有益效果
本发明结构结构设计合理，通过分拣盘、储料箱、筛选模板、铝圈输出导向轨道、铝圈出料轨道以及气动夹紧式取料组件的结构设计结合，能够保证铝圈在下料分拣过程中不变形，且对变形的铝圈进行及时的剔除，并列对铝圈的上端口和下端口进行统一筛选调整，满足装配时铝圈上端口朝上，而且保证取料装配时保证铝圈不变形，实现了将大量的铝圈进行排列输送、筛选、导向、取放料的过程，满足了自动化装配生产的加工要求。

一种瓶盖铝圈分拣系统，包括有分拣盘1，分拣盘1的正上方架设有储料箱2，储料箱2的底端设有向分拣盘1间隙抖动式投料的出料槽3，分拣盘1的周边固定安装有圆形围挡4，圆形围挡4内侧壁上分布有螺旋向上设置的导向轨道5，导向轨道5的出料端设置有用筛选铝圈朝向的筛选模板6，筛选模板6的出料端设置有与其对接有铝圈输出导向轨道7，铝圈输出导向轨道7的出料端设置有铝圈出料轨道8，铝圈出料轨道8的出料端设置有气动夹紧式取料组件9。
 本发明的实施方式
一种瓶盖铝圈分拣系统，包括有分拣盘1，分拣盘1的正上方架设有储料箱2，储料箱2的底端设有向分拣盘1间隙抖动式投料的出料槽3，分拣盘1的周边固定安装有圆形围挡4，圆形围挡4内侧壁上分布有螺旋向上设置的导向轨道5，导向轨道5的出料端设置有用筛选铝圈朝向的筛选模板6，筛选模板6的出料端设置有与其对接有铝圈输出导向轨道7，铝圈输出导向轨道7的出料端设置有铝圈出料轨道8，铝圈出料轨道8的出料端设置有气动夹紧式取料组件9。
进一步，储料箱2的底端部设有出料口，出料槽3由底板、后板和两侧板构成的槽体，槽体的后端部两侧分别通过吊环10，吊环10通过拉簧11与储料箱2的底端部弹性连接固定，出料槽的后板焊接有耳板12，耳板12上铰接有过渡板13，过渡板13固定安装在传动轮的偏心轴上，传动轮固定安装在驱动电机14的输出轴端。通过由底板、后板和两侧板构成的出料槽，其具有一定的缓存储料功能，其悬吊于出料口的下方，出料的驱动通过驱动电机转动，带动传动轮转动，从而带动偏心轴转动，过渡板的一端随着偏心轴转动，另一端实现往复运动，从而实现出料槽的间隙抖动式投料。
进一步，分拣盘1包括有盘体，盘体的中心轴转动安装在其下方的底座15上，盘体的上端面呈锥形面，导向轨道5的截面为板体结构，板体呈倾斜设置，从内至外倾斜角度为5-15°，板体的宽度约为一个铝圈的直径，且导向轨道的螺距大于一个铝圈的直径。通过盘体中部的锥形面的结构，具有一定的导向性，使下料的铝圈沿着盘体的边缘分布，同时在转动离心的作用下传动至导向轨道，通过导向轨道的结构，可使一同位置的导向轨道的板体上只能存留一个水平放置的铝圈，但有可能会存在两个铝圈竖直过来的，从而保证了分拣过程中铝圈有序的排列，保证分拣的高效进行。导向轨道5最上方的一段板体内侧设置有将铝圈整齐排放输出的导向面16，导向面16紧邻出料端，导向面16为斜坡面，且斜坡面的倾斜角度为10-30°，其外侧面与最上方导向轨道5的内侧面对接，导向面16的上方架设有将铝圈逐个输出的导向板17，导向板17为弧形板，其设置在导向面16的出料端至出料端的导向轨道5的内侧边，导向轨道5的出料端内侧设有辅助导向的弧形导板18，弧形导板18沿出料端导向轨道5的内侧面设置。通过导向轨道最上方出料端设置的导向面结构，其一方面通过导向面的角度的设置，可保证竖直导向移动过来的放不稳，从而使其水平放置，另一方面可用于缓存出料端的铝圈，配合导向板的结构，可将铝圈进行逐个输出。
进一步，筛选模板6包括有与导向轨道5过渡对接且沿导向轨道圆周方向上设置的弧形底板6-1，弧形底板6-1沿其长度方向上开设有间隔设置的弧形漏料开口一6-2和弧形漏料开口二6-3，弧形漏料开口一6-2的下方设有倾斜向下设置的接料槽6-4，弧形漏料开口二6-3的下方设有倾斜向下设置的导料槽6-5，所弧形底板6-1的两侧边分别设有向上翻折的挡边6-6，弧形漏料开口二6-3处的弧形底板6-1内侧安装有弧形限位挡板一6-7，外侧安装有弧形限位挡板二6-8，弧形限位挡板二6-8距离弧形底板的高度略小于铝圈的高度，且弧形限位挡板二6-8的内侧面位于对应的弧形漏料开口二6-3外侧面的内侧，弧形限位挡板一6-7的高度距离弧形底板6-1的高度与铝圈的高度配合，弧形限位挡板一6-7厚度小于铝圈翻边沿口的宽度。
通过筛选模板的结构，其结构是针对逐个水平导向输出的铝圈进行再次筛选，通过弧形漏料开口一对变形的铝圈进行剔除，通过弧形漏料开口二以及两侧的弧形限位挡板一和弧形限位挡板二结构的配合，由于弧形限位挡板一厚度小于铝圈翻边沿口的宽度，因此如果铝圈的上端口朝上，且铝圈的上端口则不能沿弧形限位挡板一的底端面与弧形底板以及挡边之间构成卡放铝圈侧壁的卡槽导向，铝圈只有内侧的底边有支撑，其则会向外侧倾倒而落料，若铝圈的下端口向上，其铝圈的内侧边底端通过弧形底板支撑，侧边则正好卡放到卡槽内，弧形限位挡板一的底端部对其上端部进行限位，从而使其能够在弧形限位挡板二的内侧面的抵紧力，弧形底板的底部支撑，弧形限位挡板一的上端限位构成三点支撑，从而使在后方铝圈的推力下能够导向通过，对水平输送过来的上端面向上的铝盖进行剔除，下端口朝上的铝圈则继续导出，从而保证了合格切开口朝向统一的铝圈进行到铝圈输出导向轨道上。弧形漏料开口一6-2的宽度略小于铝圈的直径，弧形漏料开口二6-3的宽度略小于弧形漏料开口一的宽度大于铝圈的半径，弧形漏料开口二的长度为两个铝圈的直径，弧形漏料开口一的长度大于弧形漏料开口二的长度。通过对弧形漏料开口一和弧形漏料开口二的长度和宽度限制，从而使变形的剔除和上端口朝向顺利的落料，尺寸过大或过小都会影响其剔除工作。
进一步，铝圈输出导向轨道7由多段槽体组成，其包括有进料段7-1，中间过渡段7-2和出料段7-3，进料段7-1的槽体的截面为U形结构，且U形槽的宽度略大于铝圈的高度，其进料端与筛选模板6的出料端对接且略低于筛选模板6的出料端，从而保证从筛选模板6出料端进入到铝圈输出导向轨道7的进料段7-1时铝圈呈竖向结构，中间过渡段7-2为L形板体结构，其L形板体的底端面为倾斜向外设置的板体，L形板体的进料端上方架设有沿其长度方向设置的挡条19，挡条19从进料至出料方向上略倾斜向下设置，且出料端的挡条19距离L型板体底端面的距离略大于铝圈的高度，出料段7-3为横向设置的U型槽体，且U型槽体的内侧边设有与其长度方向配合的限位挡边20，U型槽体的进料端与中间过渡段7-2L形板体的底端面对接，U型槽体的进料端与铝圈出料轨道8对接。
进一步，铝圈出料轨道8包括有槽体8-1，槽体8-1的出料端设有方便取料的弹性限位组件21，槽体8-1的底端面下方设有气腔，槽体的底端面上分布有间隔设置的出气口8-2，出气口8-2与气腔连通，气腔的进气口通过鼓风机，槽体8-1的正上方设有高度可调的压条8-3，压条8-3的两端分别通过螺杆固定在槽体8-1一侧的固定耳8-4上，固定耳8-4上开设有U形槽，螺杆的固定端穿过U形槽且通过锁紧螺纹固定安装在固定耳8-4上。通过槽体底端气腔的结构，为铝圈在槽体输送提供动力，通过槽体上方的压条的结构，可保证铝圈在槽体中连续输送的稳定性，避免其受其底端的出气口气力的作用而飞出的现象。弹性限位组件21包括有限位挡块21-1，限位挡块21-1上开设有用于容纳出料端端部铝圈的卡槽21-2，限位挡块21-1的底端卡装在固定座21-3上，限位挡块21-1的底端设有导柱21-4，固定座21-3上分布有与导柱21-4导向配合的导向孔，限位挡块21-1与固定座21-3之间的导柱21-4上套装有弹簧21-5，导柱21-4的底端套装有限位块21-6，限位挡块21-1的上端面的卡槽的外侧开设有方便取料卡爪动作的台阶面21-7。通过限位挡块的结构，可实现铝圈输出的限位，从而对铝圈出料的位置进行限位，而限位挡块通过导柱和弹簧安装在其下方的固定座上，采用了导向浮动的结构，一方面不影响其限位，另一方面由于铝圈的中空的结构，而且比较软，因此无法采用传统的吸盘的取放料的结构，其浮动的空间，在保证铝圈定位的同时，方便了本申请中的气动夹紧式取料组件的夹取操作。
进一步，气动夹紧式取料组件9包括有架设在铝圈出料轨道8正上方的固定梁9-1，固定梁9-1上导向安装有水平移动的滑座9-2，滑座9-2的移动通过水平移动气缸驱动，滑座9-2的底端安装有活塞杆伸出端竖直向下设置的升降气缸9-3，升降气缸9-3的活塞杆伸出端安装有夹持固定座9-4，夹持固定座9-4的底端部安装有导向座9-5，导向座9-5的中部设有两对称设置的锥形槽9-6，锥形槽9-6内分别安装有锥形导块9-7，锥形导块9-7的上端分别铰接有驱动杆9-8，驱动杆9-8的上端部均铰接在取放气缸9-9的活塞杆伸出端，夹持固定座9-4上开设有供驱动杆活动的空腔9-10，锥形导块9-7的底端面分别固定安装有夹持块9-11，夹持块9-11的夹持端面上分别设有用于卡装铝圈的半圆形卡槽9-12，半圆形卡槽9-12内壁设有固定有橡胶层9-13。通过水平移动气缸带动滑座的移动，满足了取放料位置移动的要求，通过升降气缸带动夹持固定座的结构上下移动，满足取放料过程中竖向位置移动的要求，通过导向座的结构，保证锥形导块在移动范围，保证夹持块的夹持的开合空间，取放气缸动作，带动驱动杆升降，从而带动锥形导块在锥形槽内移动，从而实现了夹持块的开合动作，通过橡胶层的结构，可使其夹持端面是弹性夹紧，从而保证了铝圈在夹持过程中不容易变形。
 工业实用性
通过分拣盘上方的储料箱结构，一方面可将大量的备料铝圈放置到静置的储料箱内进行储放，而分拣盘的供料则通过间隙抖动式投料的出料槽，进行间断式的出料，出料掉落至分拣盘上即可实现少量的铝圈产品随着分拣盘的转动进行有规律的分拣，分拣时，产品在分拣盘转动的离心力的作用下，铝圈进入到圆形围挡内壁的导向轨道，随着转动的进行，铝圈不断的进入，从而推动前面的铝圈沿着导向轨道和圆形围挡内壁螺旋导向移动，直至移动到最上方的导向轨道处，即完成了对落料的铝圈进行逐步分拣排列。
从导向轨道输出的铝圈虽然均是水平排列的，但由于铝圈比较软因此在落料或者分拣过程中有可能会出现变形的情况，变形的铝圈肯定是不合格品，因此需要对其进行剔除，并列铝圈的上端口和下端口的结构不同，因此需要对其端面朝向进行调整，本申请中通过筛选模板，首先通过弧形漏料开口一对变形的铝圈进行剔除，通过弧形漏料开口二以及两侧的弧形限位挡板一和弧形限位挡板二结构的配合，对水平输送过来的上端面向上的铝盖进行剔除，下端口朝上的铝圈则继续导出，从而保证了合格切开口朝向统一的铝圈进行到铝圈输出导向轨道上。
通过铝圈输出导向轨道的结构，可对从筛选模板出来的铝圈进行调整方向，使其上端口朝向上方，从而满足铝圈装配时的朝向的要求，其具体过程时，首先通过进料段的槽体的结构，将输出的下端口朝向的铝圈进行竖向排列，先竖向输送，然后进入到中间过渡段，配合挡条的结构，可对其竖向排列的铝圈进行限位，使其朝向挡条的另一侧进行翻转，且挡条出料端和中间过渡段的板体之间构成导向通道，从而使得输出的铝圈均是上端口朝上，之后再通过出料端的U型槽体和限位挡边通过的输送通道进行导向，从而保证铝圈的输出。
对铝圈进行调整方向之后进入到铝圈出料轨道上，沿着铝圈出料轨道进行整体的排列，然后再通过出料端的气动夹紧式取料组件进行夹取放置到装配线上，从而满足自动化取料装配的要求。
