Description

用于焊接连续卷材的旋转装置
技术领域
本发明涉及一种连续卷材的旋转焊接装置。
特别地，根据本发明的装置被构造为根据预定的焊缝间距沿着与卷材馈送方向横切的方向焊接卷材。
背景技术
众所周知，旋转焊接装置使用支撑多个焊接单元的旋转元件，该多个焊接单元被构造为在旋转元件围绕其自身的旋转轴线进行旋转期间焊接连续卷材。
焊接单元相对于旋转元件的旋转轴线的径向定位限定了焊接单元的预定的工作圆周，从而限定了相应的焊缝间距。
为了改变装置的焊接步骤，需要改变焊接单元相对于旋转元件的旋转轴线的径向定位，以确定获得期望的焊接步骤所沿的工作圆周。
发明内容
在这种背景下，为了能够改变用于焊接连续卷材的步骤，有必要制造一种用于焊接连续卷材的旋转装置，其包括围绕其自身的旋转轴线旋转的旋转元件、由该旋转元件支撑的用于支撑连续卷材的一个或多个支撑元件以及由旋转元件支撑的用于焊接连续卷材的多个焊接单元。
每个焊接单元被构造为从非操作位置转移到操作位置，或者反过来转移。
每个焊接单元包括相应的焊嘴和能相对于焊嘴移动的相应的砧座元件。
每个焊接单元包括相应的第一移动装置，其被构造为驱动砧座元件相对于焊嘴从砧座元件与焊嘴成角度地间隔开的初始位置旋转到最终位置，或者反过来旋转。
在最终位置，焊嘴的表面和砧座元件的表面彼此平行，并且与焊嘴的所述表面成直角的轴线和与砧座元件的所述表面成直角的轴线沿着同一条对齐轴线对齐。
每个焊接单元包括用于使砧座元件相对于焊嘴从起始位置移动到到达位置或者反过来移动的第二移动装置，在起始位置焊嘴的表面和砧座元件的表面彼此平行并且沿着同一条对齐轴线彼此对齐，在到达位置砧座元件的表面和焊嘴的表面在介于它们之间的相应区域中接触连续卷材的相应部分。
第一驱动装置驱动第一移动装置以使砧座元件从初始位置转移到最终位置，或者反过来转移。
第二驱动装置驱动第二移动装置以引起从起始位置到到达位置的转移，或者反过来转移。
第一驱动装置和第二驱动装置被构造为改变焊嘴相对于旋转元件的旋转轴线的相对定位。
有利地，第一驱动装置和第二驱动装置允许根据所需的焊缝间距确定相应的焊接单元的工作圆周。
附图说明
本发明的其他特征及其优点在下面对附图所示的用于连续卷材的旋转焊接装置的优选但非排他性的实施方式的非限制性描述中变得更加清楚，在附图中：
图1是根据本发明的吸水制品的旋转焊接装置的示意性正视图；
图2是由图1的装置处理的连续卷材的示意性平面图；
图3是处于非操作位置的图1的焊接单元的示意性侧视图；
图4是处于操作位置的图1的焊接单元的示意性侧视图。
具体实施方式
本说明书中的附图标记1表示连续卷材的旋转焊接装置。
本说明书的装置1被构造为根据焊缝间距P焊接连续卷材2。
连续卷材2具有用于通过装置1根据焊缝间距P进行焊接的至少两条重叠的边缘。
连续卷材2具有主要的纵向延伸部L。
装置1被构造为沿着与纵向延伸部L的方向横切的方向T焊接连续卷材2。
更具体地，参照图2，装置1根据焊缝间距P在相应的焊接区域4中沿着连续卷材2的横向方向T形成多条焊缝。
例如，连续卷材2是吸水制品的连续带材，特别是尿裤(所谓的“训练裤”)的连续卷材。
该连续带材是沿着吸水垫的中心线折叠的一系列吸水制品。
例如，根据本发明的装置被构造为焊接吸水制品或尿布的连续卷材，以焊接围绕使用者的腰部的尿裤的弹性侧收缩部。
根据另外的例子，连续卷材2是容纳液体(具体是诸如饮料的液体食品)或诸如注入用物质的固体食品的小袋的连续带材。
在装置1的下游，切割装置(未被示出)作用在连续卷材2的每个焊接区域4处、特别是它们各自的中心线处，以用于分离出独立长度3的连续卷材2。
旋转焊接装置1包括围绕旋转轴线5a旋转的旋转部件5。
旋转部件5的旋转轴线5a优选为水平轴线。
替代地，旋转部件5的旋转轴线5a是竖直轴线。
装置1包括用于焊接连续卷材2的多个焊接单元6。
焊接单元6安装在旋转部件5上，并因此围绕旋转部件5的旋转轴线5a旋转。
焊接单元6围绕旋转部件5的旋转轴线5a成角度地彼此等距分隔开。
焊接单元6的周向间距决定了连续卷材2的焊接区域4的焊缝间距“P”。
因此，由焊接单元6围绕旋转部件5的旋转轴线5a的间距限定的直径是可变参数。
每个焊接单元6包括相应的焊嘴7和焊嘴7的相应的相对元件8或砧座元件8。
每个焊接单元6的砧座元件8具有用于连续卷材2的相应部分的接触表面8a。
砧座元件8的接触表面8a具有与表面8a正交的轴线8b。
接触表面8a具有预定的焊接图案。
每个焊接单元6的焊嘴7具有用于连续带材2的相应部分的接触表面7a。
焊嘴7的接触表面7a具有与表面7a正交的轴线7b。
优选地，焊嘴是超声焊嘴7。
替代地，焊嘴7是热机械焊嘴。
优选地，焊接单元6的每个焊嘴7朝向旋转部件5的内侧设置，而相应的砧座元件8朝向外侧设置。
以这种方式，优化了相关的总体尺寸，使该方案更加紧凑并因此是优选的。
每个焊接单元被构造为从非操作位置转移到操作位置，或者反过来转移。
在非操作位置，砧座元件8的表面8a与和连续卷材2的部分进行接触的焊嘴7的表面7a相对地间隔开(见图3)。
在非操作位置，与焊嘴的表面7a正交的轴线7b投射到与砧座元件8的表面8a正交的轴线8b上。
在焊接单元6的操作位置，砧座元件8的表面8a和焊嘴7的表面7a与介于它们之间并预期会变成焊接区域4的连续卷材2的相应部分进行接触。
在操作位置，与焊嘴的表面7a正交的轴线7b和与砧座元件8的表面8a正交的轴线8b沿着同一条对齐轴线V对齐。
装置1包括用于支撑连续卷材2的多个支撑元件9。
用于支撑连续带材2的支撑元件9安装在旋转部件5上，并因此围绕旋转部件5的旋转轴线5a旋转(见图3)。
焊接单元6和支撑元件9彼此交替地安装。
换句话说，每个焊接单元6介于相应的一对支撑元件9之间。
每个支撑元件9具有用于保持连续卷材2的保持表面12。
每个支撑元件9的保持表面12优选是弧形表面。
替代地，每个支撑元件9的保持表面12优选是平坦表面。
优选地，支撑元件9被构造为通过吸力来保持连续卷材2。
在此方面，保持表面12设有抽吸孔图案。
装置1包括用于馈送要被焊接的连续卷材2的工位10和经过焊接的连续卷材2的出料工位11。
通过围绕旋转轴线13a进行旋转的辊13(优选为抽吸辊)馈送连续卷材2通过馈送工位10，使其以不打滑的方式卷绕在支撑元件9的保持表面12上。
应注意的是，如果连续卷材2是吸水制品的连续带材，则其在装置1的支撑元件9上被卷绕为使得连续系列的重叠的弹性收缩部面朝装置的可由操作员接近的前部。
通过围绕旋转轴线14a旋转的辊14(优选为抽吸辊)将经过焊接的连续卷材2通过出料工位11送出。
连续卷材2的馈送辊13的旋转轴线13a和经过焊接的连续卷材2的输送辊14的旋转轴线14a彼此平行。
旋转元件5的旋转轴线5a平行于连续卷材2的馈送辊13的旋转轴线13a和经过焊接的连续卷材2的输送辊14的旋转轴线14a。
根据本发明，每个焊接单元6包括第一移动装置15，其用于通过施加使砧座元件8朝向焊嘴7移动的运动和使砧座元件8远离焊嘴7移动的运动而使砧座元件8相对于焊嘴7移动。
朝向的运动包括将砧座元件8定位在其与焊嘴7对齐的位置处(即，协同位置)，使得砧座元件8的接触表面8a平行于焊嘴7的接触表面7a并且使得与砧座元件8的接触表面8a正交的轴线8b和与焊嘴7的接触表面7a正交的轴线7b沿着同一条对齐轴线V对齐。
第一移动装置15被构造为驱动砧座元件8相对于焊嘴7从初始位置旋转到最终位置或者反过来旋转，在该初始位置砧座元件8与焊嘴7成角度地间隔开，在该最终位置焊嘴7的表面7a和砧座元件8的表面8a彼此平行并且沿着同一条对齐轴线V彼此对齐。
在初始位置，与砧座元件8的表面8a正交的轴线8b的方向特别是以形成锐角的方式投射到与焊嘴7的表面7a正交的轴线7b的方向上。
第一移动装置15包括至少一个铰接系统30，其包括至少一个控制曲柄19以及通过曲柄19进行移动的杠杆21，该杠杆21相对于其摆动轴线21a进行摆动。
杠杆21围绕摆动轴线21a的摆动引起砧座元件8朝向和远离焊嘴7移动，也就是说，引起砧座元件8相对于焊嘴7从初始位置转移到最终位置或者反过来转移。
第一移动装置15包括与曲柄19连接的至少一个第一连杆20以及与第一连杆20和杠杆21连接的第二连杆22。
第一连杆20和第二连杆22将受控的运动从曲柄19传递至杠杆21。
特别地，第二连杆22在相对于杠杆21的主要纵向延伸部的中心位置处连接至杠杆21。
第一连杆20通过销38被可旋转地连接至曲柄19。
将第一连杆20连接至曲柄19的销38与曲柄19形成为一体。
第二连杆22通过与杠杆21形成为一体的销39被可旋转地连接至杠杆21的相应部分。
第一连杆20通过销40被可旋转地连接至第二连杆22。
第一移动装置15的曲柄19、第一连杆20、第二连杆22和杠杆21限定了铰接的“肘节”系统。
第一移动装置15包括彼此相对设置的一对铰接系统30。
根据替代的实施方式，针对每个焊接单元6，第一移动装置15都包括同步驱动的双铰接“肘节”系统。
曲柄19的逆时针旋转引起第一连杆20和第二连杆22的相对运动，使相应的杠杠21围绕摆动轴线21a在顺时针方向上摆动，使得砧座元件8相对于焊嘴7从初始位置转移到最终位置或者反过来转移。
参考所示的实施方式，曲柄19的顺时针反向旋转引起相应的杠杆21围绕摆动轴线21a的逆时针摆动，使得砧座元件8远离焊嘴7移动，也就是说，从最终位置转移到初始位置。
在砧座元件8相对于焊嘴7的最终位置，至少第一连杆20和第二连杆22在相对于杠杆21的位置倾斜的位置处彼此对齐。
特别地，在相互对齐的位置，至少第一连杆20和第二连杆22沿着与杠杆21的位置成直角的方向定位。
在该相互对齐的位置，从曲柄19到杠杆21，连接销38、39、40定位为彼此平行。
第一驱动装置17控制第一移动装置15的运动。
曲柄19、第一连杆20、第二连杆22和杠杆21在砧座元件8相对于焊嘴7的最终位置处采用的构造使得焊接力不会传递至第一驱动装置17，因为该力被第一移动装置15的铰接系统30所采用的构造减除。
第一驱动装置17控制第一移动装置15的铰接系统30的曲柄19的运动。
第一驱动装置17被构造为可相对于旋转元件5的旋转轴线5a在径向方向上移动。
有利地，第一驱动装置17的径向运动允许改变每个焊接单元6的工作圆周，而不改变第一移动装置15的铰接系统30的元件，因此这保持了其运动传动比。
每个焊接单元6包括第二移动装置16，其用于使砧座元件8相对于焊嘴7从起始位置移动到到达位置，在该起始位置砧座元件8的接触表面8a和焊嘴7的接触表面7a彼此平行并且沿着同一条对齐轴线V彼此对齐，在该到达位置砧座元件8的接触表面8a和焊嘴7的接触表面7a与介于它们之间的连续卷材2进行接触。
到达位置对应于焊接单元6的操作位置。
从起始位置到到达位置，砧座元件8朝向相应的焊嘴7平移，直到它与介于它们之间的连续卷材2接触。
相反，第二移动装置16被构造为使砧座元件8远离焊嘴7平移，从而脱离介于它们之间的连续卷材2。
第二移动装置16由第二驱动装置18进行驱动。
第二移动装置16包括至少一个铰接系统33，其包括用于对被可旋转地连接至杠杆21的摆动轴线21a的连杆35进行控制的曲柄34。
曲柄34和连杆35通过销41被可旋转地连接。
销41连接至曲柄34。
曲柄34、连杆35和杠杆21限定了铰接的“肘节”系统33。
根据替代的实施方式，针对每个焊接单元6，第二移动装置16都包括同步驱动的双铰接“肘节”系统。
在到达位置，连杆35沿着与曲柄34成直角的方向定位。
在到达位置，连杆35沿着与杠杆21成直角的方向定位。
第二移动装置16包括彼此相对设置的一对铰接系统33。
第二移动装置16包括气动系统37，其被构造为用于确定借助于上述铰接系统33进行的相对于焊嘴7朝向或远离砧座元件8的平移或者反过来的平移。
气动系统37允许在砧座元件8和焊嘴7之间施加并保持预定压力，以使压力在整个焊接过程中(即，只要焊接单元6处于操作位置)保持尽可能恒定。
当启动焊嘴7形成焊接区域4时，介于砧座元件8的表面8a与焊嘴7的表面7a之间的连续卷材2的区域被焊接。
气动系统37连接至第二移动装置16的曲柄34。
气动系统37包括活塞44，其杆45被可旋转地连接至臂46，该臂46被可旋转地连接至第二移动装置16的曲柄34。
在到达位置，与活塞44的杆45连接的臂46与连接至曲柄34的臂46以及曲柄34对齐。
这种对齐有利地可以将气动系统37产生的力直接传递至焊嘴7。
铰接系统33的杠杆比使气动系统37产生的力加倍。
有利地，这种对齐允许气动系统产生的力与第二移动装置16的铰接系统33隔离开，从而防止它们影响第二驱动装置18。
第二驱动装置18控制第一移动装置15的铰接系统30的曲柄19的运动。
第二驱动装置18被构造为可相对于旋转元件5的旋转轴线5a在径向方向上移动。
有利地，第二驱动装置18的径向运动允许改变每个焊接单元6的工作圆周，而不改变第二移动装置16的铰接系统33的元件，因此这保持了其运动传动比。
第一驱动装置17和第二驱动装置18包括单个控制构件26以及相应的第一驱动传递单元32和第二驱动传递单元24。
控制单元26包括围绕相应的旋转轴线旋转的转鼓29，其在外周表面上具有用于凸轮从动辊27的多条滑动轨道28。
第一运动传递单元32包括杆状元件31，其在一端具有至少一个凸轮从动辊27，该凸轮从动辊27被构造为接合在转鼓29的相应的轨道28中。
杆状元件31相对于旋转元件5的旋转轴线5a在径向方向上延伸。
转鼓的轨道28被构造为沿着至少一个伸展部产生杆状元件31的旋转。
杆状元件31的旋转引起第一移动装置15的运动。
第一驱动传递单元32包括至少一个旋转传递元件43，其将旋转从杆状元件31传递给第一移动装置15的铰接系统30的曲柄19。
传动元件43被可滑动地约束在杆状元件31上，以改变砧座元件8的径向位置。
在沿着杆状元件31采用的任何位置，传递元件43都受到杆状元件31的旋转的约束。
曲柄19通过轴25被可旋转地连接至传动元件43，该轴25围绕其旋转轴线25a旋转。
双铰接系统30的曲柄19连接至轴25。
第二运动传递单元24包括杆状元件23，其在一端具有至少一个凸轮从动辊27，该凸轮从动辊27被构造为接合在转鼓29的相应的轨道28中。
杆状元件23相对于旋转元件5的旋转轴线5a在径向方向上延伸。
转鼓的轨道28被构造为沿着至少一个伸展部产生杆状元件23的旋转。
杆状元件23的旋转对运动传递单元32产生致动，以使第二移动装置16进行移动。
第二驱动传递单元24包括至少一个旋转传递元件48，其将旋转从杆状元件23传递给第二移动装置16的铰接系统33的曲柄19。
传动元件48被可滑动地约束在杆状元件23上，从而能够改变砧座元件8的径向位置。
在沿着杆状元件23采用的任何位置，传动元件48都受到杆状元件23的旋转的约束。
曲柄34通过轴49被可旋转地连接至传动元件48，该轴49围绕其旋转轴线49a旋转。
双铰接系统33的曲柄34连接至轴49。
杆状元件23的旋转对运动传递单元24产生致动，以使第二移动装置16进行移动。
有利地，使第一驱动装置17的运动传递元件43和第二驱动装置18的运动传递元件48沿着相应的杆状元件31、23平移的可能性可以改变砧座元件8相对于旋转元件5的旋转轴线5a的位置。
这种位置变化可以根据焊缝间距来限定工作圆周。
