Description
本发明涉及包装袋加工设备领域，具体而言涉及一种双层袋的内袋与外袋粘合机构及粘合方法。
双层袋主要应用在化工原料、各类化肥、食品原料添加剂以及动物饲料等容易受潮的产品。外袋体一般为编织袋(PP材质)、BOPP复膜袋、淋膜袋或者纸塑复合袋。内袋体则采用PE膜，分为LDPE低压膜及HDPE高压膜。双层袋目前一般都采用超声波人工封袋口，但超声波长期长时间噪音及辐射对人体有一定损伤。而且，该种封袋方式也同时需要使用人工进行封口，但人工重复动作耗损体力巨大，特有的封口动作需要专业培训后才能上岗工作。
此外，双层袋的制造是将内袋体一端开口加热封合后，再套设入外袋体的内部。内袋体与外袋体的开口端则利用加热或是黏着处理的方式，将外袋体的开口内侧面与内袋体开口的外侧面相互接合。
以上可知，现有技术中用于生产双层袋的设备的生产流程比较复杂，且结构较为繁琐，影响设备稳定性能及生产效率。因此，提出一种生产流程及结构均较为简单的双层袋制造设备是亟需解决的技术问题。

下面将结合附图和具体实施方式，对本发明的技术方案作详细说明，应理解这些实施方式仅用于说明本发明而不用于限制本发明的范围，在阅读了本发明之后，本领域技术人员对本发明的各种等价形式的修改均落入本申请所附权利要求所限定的范围内。
实施例
请参考图1-图6所示，本发明的实施例公开了一种双层袋的内袋与外袋粘合机构。该双层袋的内袋与外袋粘合机构主要包括基座10、第一吸盘20、第二吸盘30、第三吸盘40以及接合装置50等。相较于现有技术中粘合机构的接合装置50位于外袋81外侧的设置方式，本发明的双层袋的内袋与外袋粘合机构的接合装置50可与第三吸盘40设置在一起且可以从双层袋80的内袋82的内侧来粘合外袋81和内袋82，进而避免了前述背景技术中所提到的技术问题，使得整个粘合外袋81及内袋82的动作减少，生产效率及稳定性显著提高。
请参考图8所示，本发明所指的双层袋80为具有内袋82及外袋81的结构。内袋82及外袋81的同一端分别具有一个开口，另一端封闭。内袋82可以套设在外袋81的内部且内袋82及外袋81开口的一端可以连接到一起。在本实施例中，外袋81可以为PP聚丙烯的编织袋，内袋82可以为PE膜的袋体。粘合是指外袋81和内袋82可以通过加热方式破坏，冷却融合后在一起。外袋81及内袋82的设计方式，使得双层袋80在具有一定强度的同时，还能使装入袋中的物料与外部相隔离，从而实现密封防潮的效果。
请参考图1所示，双层袋的内袋与外袋粘合机构的基座10大体可以包括上座11和下座12。本实施例的上下方向为面上纸面的上下方向。基座10的两侧可以分别设置一类似E字形结构13。E字形结构13的上面两个横向设置的结构可以为上座11，E字形结构13下面一个横向设置的结构可以为下座12。例如，两个类似E字形结构13的下部连接到一起，进而形成下座12结构，其余结构为上座11。两个E字形结构13的中间可以分别设置有各部件，例如第一吸盘20、第二吸盘30、第三吸盘40以及接合装置50等。但本申请的基座10并不限于该实施例所列的结构，基座10的形状可以根据实际的需求来进行改变。
第一吸盘20用于吸附外袋81并将吸附到的外袋81提升或者放下。第一吸盘20可以设置于基座10上，且可以位于基座10的上座11的前方位置处。本实施例中，需要说明的，以远离第三吸盘40的方向为前方，以靠近第三吸盘40的方向为后方。
第一吸盘20可以包含第一上吸盘21及第一下吸盘22。第一上吸盘21与第一下吸盘22相对设置且相对的两个侧面上可以分别设置有多个吸孔。第一上吸盘21及第一下吸盘22可相对于上座11上下移动。第一上吸盘21可选择性地贴合于第一下吸盘22。第一吸盘20用以吸附双层袋80的外袋81。具体的，第一上吸盘21通过吸孔吸附外袋81的上侧面，第一下吸盘22通过吸孔吸附外袋81的下侧面。第一上吸盘21借由设置于基座10上的第 一伺服电机23驱动可向下移动直至贴靠于第一下吸盘22，亦或是向上移动与第一下吸盘22保持一特定距离，进而能打开及关闭外袋81的开口。
在另一可选的实施例中，为了配合接合装置50对外袋81及内袋82进行粘合，第一上吸盘21及第一下吸盘22具有吸孔的一面上还设置有刀垫25。该刀垫25可以具有一定的弹性及耐热性，当第一上吸盘21及第一下吸盘22下压接合装置50时，刀垫25可以起到隔热及缓冲的作用。
第二吸盘30用于吸附内袋82并将吸附到的内袋82提升或者放下。第二吸盘30可以设置于基座10上，且相对于第一吸盘20靠后设置一点。同样的，第二吸盘30包含第二上吸盘31及第二下吸盘32。第二上吸盘31与第二下吸盘32相对设置且相对的两个侧面上可以分别设置有多个吸孔。
在一可选的实施例中，第二上吸盘31及第二下吸盘32的吸附面上沿横向及纵向开设有多个凹槽。多个凹槽等间隔地排布进而能将吸附面分割为多个矩形区域。吸孔设置在矩形区域内。这种吸附面的设计方式可以保证第二吸盘30具有比较好的吸附效果。
在对内袋82及外袋81粘合时，第二上吸盘31及第二下吸盘32可相对于上座11上下移动。第二上吸盘31可选择性地贴合于第二下吸盘32。在本实施例中，第二吸盘30用以吸附双层袋80的内袋82。第二上吸盘31可相对于上座11上下移动。在本实施例中，第二吸盘30用以吸附双层袋80的内袋82外侧面。具体的，第二上吸盘31通过吸孔吸附内袋82的上侧面，第二下吸盘32通过吸孔吸附内袋82的下侧面。第二上吸盘31借由设置于基座10上的伺服电机驱动可向下移动直至贴靠于第二下吸盘32，亦或是向上移动与第二下吸盘32保持一特定距离，进而能打开及关闭内袋82的开口。
第一上吸盘21及第一下吸盘22可以与设置在上座11上的第一滑轨24滑动连接。具体的，第一滑轨24可以沿上下方向设置在基座10的上座11的位置，从而使得第一上吸盘21及第一下吸盘22能在上下方向上相对上座11滑动。
为了保证第一吸盘20和第二吸盘30能同步运动，从而能对内袋82及外袋81同步的吸附，第一吸盘20和第二吸盘30可以固定连接到一起。例如，在对双层袋80进行粘合时，外袋81和内袋82可以同步地分别被第一吸盘20和第二吸盘30吸起，进而能同步打开外袋81及内袋82的开口，从而保证第三吸盘40及接合装置50能较为方便地插入到内袋82内。第一上吸盘21及第一下吸盘22上可以分别设置有第二吸盘30连接调节座，第二上吸 盘31及第二下吸盘32再分别与第二吸盘调节座37固定连接，从而使得第一吸盘20与第二吸盘30能固定连接到一起。
较佳的，第二吸盘30能调节在第二吸盘调节座37上的位置，进而调节第一吸盘20与第二吸盘30之间的相对位置。例如，可以根据内袋82端部超出外袋81端部的距离而调节第一吸盘20和第二吸盘30之间的相对位置，从而保证第一吸盘20和第二吸盘30能准确地吸取并提升起外袋81和内袋82。当然，可以理解的，在其他的实施例中，第一吸盘20与第二吸盘30之间的连接的方式还包括其他的形式，本申请对此不做限制。
在本实施例中，第一吸盘20及第二吸盘30可以通过第一伺服电机23的驱动而运动。相比于现有技术采用气缸的驱动方式。伺服电机可以精确计算行程及反馈信息，且可以做悬停步进等动作，进而能准确地定位到需要粘合的位置。然而，气缸的控制精度不高，无法做到精确地同步吸附两侧内袋82同时进入外袋81，这样失误率导致成品率低下。因此，采用伺服电机驱动的方式可以进一步地提高产品的成品率。
为了能驱动第一吸盘20及第二吸盘30，双层袋的内袋与外袋粘合机构还包括同步轮33，凸轮传动轴34以及凸轮35。同步轮33为两个，两个同步轮33分别对应于第一上吸盘21及第一下吸盘22设置。同步轮33与凸轮传动轴34相连接，凸轮35套设在凸轮传动轴34上，第一上吸盘21及第一下吸盘22分别与凸轮35连接。第一伺服电机23与两个同步轮33传动连接，以使两个同步轮33能同步转动。
为了实现第一吸盘20及第二吸盘30具有一定的吸附力，第一吸盘20及第二吸盘30上按照预设的排列方式开设有多个吸孔，多个吸孔分别与位于第一吸盘20及第二吸盘30上的真空负压接头90相连通。真空负压接头90能与外部的真空负压设备连通。当真空负压设备开启后，第一吸盘20和第二吸盘30因此具有一定的吸附力，进而可以对外袋81及内袋82进行吸附。可以理解的，因第一吸盘20包括上下对称设置的第一上吸盘21及第一下吸盘22，两个吸盘上的结构也均相同。第二吸盘30也同理，在此不再赘述。
在本实施例中，为了能将外袋81及内袋82粘合到一起，双层袋的内袋与外袋粘合机构还可以包括第三吸盘40。第三吸盘40可以为沿着基座10的宽度方向延伸的长方形构件。第三吸盘40的长度可以与内袋82的宽度相适配，进而保证第三吸盘40能较好地对内袋82进行吸附。第三吸盘40的基本构造与前述的第一吸盘20及第二吸盘30基本一致，即第三吸盘40的上下两侧包括多个吸孔，多个吸孔与真空负压设备连接。当真空负压设备开 启后，第三吸盘40因此具有一定的吸附力，进而可以对内袋82进行吸附。第三吸盘40与第一吸盘20及第二吸盘30的不同在于，第三吸盘40仅为一个。
第三吸盘40可以滑动设置在沿基座10的前后方向设置的第二滑轨41上，使得第三吸盘40可以在前后方向上滑动。第三吸盘40的运动方向与第一吸盘20及第二吸盘30的运动方向相垂直。双层袋的内袋与外袋粘合机构还包括一第三吸盘基座43，第三吸盘基座43滑动设置在第三滑轨上，第三吸盘40设置在第三吸盘基座43上。
例如在双层袋的内袋与外袋粘合机构工作的过程中，当第一上吸盘21及第二上吸盘31分别吸附外袋81及内袋82的上侧，第一下吸盘22及第二下吸盘32分别吸附外袋81及内袋82的下侧后，在第一伺服电机23及同步轮33的带动下，第一上吸盘21及第二上吸盘31向上运动，第一下吸盘22及第二下吸盘32向下运动或保持不动，进而将外袋81及内袋82的开口打开。同时，第三吸盘40在第二伺服电机42的驱动下沿第二滑轨41滑动并伸入到内袋82内。当第三吸盘40水平前进一段处，真空负压设备打开，第三吸盘40吸附内袋82，第二上吸盘31和第二下吸盘32真空关闭。第三吸盘40水平前进二段，第三吸盘40推进使内袋82与外袋81袋口齐平绷紧。
进一步的，为了保证第二吸盘30与第三吸盘40能较好地配合，第二吸盘30与第三吸盘40可以连接到一个真空负压设备上，通过真空切换器控制真空负压设备与第二吸盘30及第三吸盘40的通断，而控制第二吸盘30及第三吸盘40吸附内袋82的时机。
当第三吸盘40推进使内袋82与外袋81袋口齐平绷紧后，接合装置50用于将内袋82与外带粘合到一起。在本实施例中，接合装置可以为热合封刀50(以下简称封刀50)。封刀50利用发热元件作用在包装容器封口部位而将外袋81和内袋82通过加热方式破坏，冷却融合后在一起，以封闭包装容器。对于本领域的技术人员来说，可以理解的，接合装置50不以此为限，任何可达到加热功效使得内袋82及外袋81产生熔化接合的装置皆可，如热熔机、超声波封口机等。
本申请的一关键创新在于，将现有技术中位于外袋81外侧的接合装置50改变为位于内袋82内，即从之前的外部粘合的方式，改变为从内部粘合。封刀50可以与第三吸盘40集成设置在一起，即第三吸盘40在从内袋82的内侧吸附内袋82的同时，封刀50可以将外袋81和内袋82粘合在一起。在本实施例中，“集成”意思是指封刀50与第三吸盘40可以设置在同一个部件上，例如，参照图5所示，封刀50可以位于第三吸盘40的后侧，从外部看，封刀50与第三吸盘40可以为一个部件。具体的，该部件可以为：封刀50与第 三吸盘40在结构上可以为先制造好封刀50及第三吸盘40，然后再将两者组装到一起；或者可以在一个结构中分别设计有封刀50及第三吸盘40，使得能在生产制造阶段一体地被制造出来，进而可以加工步骤及提高生产效率。总之，基于本发明的一个思路在于将现有技术中的位于外袋81外侧的接合装置50改变为位于内袋82内，而做出的任何能实现本发明思路的实施方式，都是落入到本专利的保护范围之内。
封刀50的结构具体可以包括位于中间的封刀基座51。该封刀基座51可以为铝制结构，进而在保证强度的前提下可以减轻封刀50的重量。较佳的，封刀基座51的表面可以涂覆特殊材料铁氟龙，进而达到齿部表面光滑，内袋82受热融化，降低黏刀的情况，使用寿命更加长，久易于维护保养。
参照图6所示，封刀基座51的上下两侧分别设置有封刀基板52。封刀基板52与封刀基座51之间可以通过弹簧53连接，使得封刀基板52能在外力的作用下相对封刀基座51运动。封刀基座51的上下两侧还沿基座10的高度方向设置有多个封刀齿54。该封刀齿54可以为大体为柱状结构的金属件，位于封刀基座51内部的加热元件可以通过热传导而将热能传递到封刀齿54上。封刀齿54再将内袋82与外袋81粘合到一起。进一步的，为了保证封刀50的安全性，封刀基板52上开设有对应于封刀齿54数量的孔。当第三吸盘40水平前进二段而使内袋82与外袋81袋口齐平绷紧后，第一上吸盘21及第一下吸盘22向内靠近并下压封刀基板52，位于第三吸盘40上下两侧的封刀基板52在第一上吸盘21及第一下吸盘22的挤压下弹簧53收缩而朝向封刀基座51运动时，封刀齿54的端部可以穿过封刀基板52的孔而露出于封刀基板52之外，粘合内袋82与外袋81。当粘合完成后，第一上吸盘21及第一下吸盘22复位，封刀基板52又能在弹簧53的带动下复位，使得封刀齿54又能位于封刀基板52之下，从而保证整个粘合过程的安全。
在另一较佳的实施例中，为了提高封刀50的强度，封刀基板52的外表面的一侧还可以设置有一层防护板，防护板可以包括铜板55或其他硬质板材。铜板55上还可以贴铁氟龙布，进而增加封刀基板52外表面的平滑度及一定程度。
较佳的，为了降低封刀50的铜板55的温度，保证外侧温度不会影响内袋82，产生变形对产品产生影响，铜板55的内侧面还可以设置有冷却装置56。该冷却装置56可以包括中空铜管，中空铜管中间通水冷却。例如，冷却装置56可以将循环水温度控制在40度以内，使得封刀50加热温度在250以下，封刀50表面温度控制在50度，不影响内膜。
在本实施例中，为了在对内袋82与外袋81粘合时，内袋82及外袋81粘合处更加地平整，双层袋的内袋与外袋粘合机构还可以包括展开装置60。该展开装置60可以包括：展开装置基座61、两个展开臂62以及驱动装置65，其中所述驱动装置65为伺服电机或气缸。所述展开装置基座61滑动设置在第二导轨上。所述展开臂62位于所述第三吸盘40的两侧。所述驱动装置65设置在所述展开装置基座61上，所述驱动装置65用于驱动所述展开臂62。当第三吸盘40伸入到内袋82内后，位于第三吸盘40两侧的展开臂62可以在驱动装置65的驱动下向第三吸盘40的左右两侧展开，进而能将内袋82及外袋81开口的一端展平，使得封刀50粘合后的内袋82及外袋81接合处更为的平整。
具体的，因展开装置60也可以滑动设置在第二滑轨41上，因此展开装置基座61与第三吸盘基座43可以为同一个，从而保证展开装置60可以与第三吸盘40及封刀50同步运动以及提高结构的紧凑。气缸可以滑动设置在导轨上，气缸借由摆臂63及展开调节丝杆64而与展开装置60的分别位于两侧的展开装置60固定连接，达到左右开合同步。需要说明的，在本实施例中，平整是指内袋82被展开臂62向外撑开，进而使得构成内袋82的膜被撑得较为平整。
在另一较佳的实施例中，所述展开臂62上还可以设置有吸孔，所述吸孔用于吸附所述内袋的内表面。
展开装置60除了应用于本实施例中外，展开装置60作为一个能单独实现具体功能的部件，其还可以应用于其他类似的双层袋制造机构中，例如，接合装置50位于外袋81外的双层袋制造机构。本申请并不对展开装置60的具体适用的机构作仅限实施例的限制。
在另一优选的实施例中，双层袋的内袋与外袋粘合机构还可以包括内袋82吹平装置70。内袋82吹平装置70可以位于上座11上且相较于第一吸盘20而更加远离第二吸盘30设置。内袋82吹平装置70用于当为粘合的外袋81及内袋82位于该机构上时，内袋82吹平装置70可以利用鼓风吹气的方式将外袋81及内袋82吹平。
为了使本领域的技术人员能更为清楚地理解本发明，以下将结合以下步骤对本发明的一种双层袋的内袋与外袋粘合机构的工作流程进行说明。
步骤一：进料(S101)
借由输送装置将双层袋80输送至基座10，其中双层袋80的内袋82的开口与外袋81的开口位于同侧边，且内袋82的开口一端突出于外袋81的开口一端形成一突出部83，当双层袋80位于作业位置时，外袋81邻近于开口的位置位于第一吸盘20的第一上吸盘21 与第一下吸盘22之间。内袋82的突出部83位于第二吸盘30的第二上吸盘31与第二下吸盘32之间。在本实施例中，突出部83突出的距离至少2cm以上，实际操作中可以根据使用情况选用突出部83的突出距离以适应不同工况，本实施例中仅提供一种实施举例但不局限于此。
较佳的，参照前述内容，双层袋的内袋与外袋粘合机构还可以包括内袋82吹平装置70。当双层带输送至基座10上后，内袋82吹平装置70开始工作，内袋82吹平装置70朝向内袋82鼓风进而平整舒展内袋82。
步骤二：撑口(S102)
前述步骤一之后，将第一吸盘20的第一下吸盘22吸住外袋81的下侧面，第一上吸盘21吸住外袋81的上侧面并且往上方移动和/或第一下吸盘22往下移动。第二下吸盘32吸住内袋82的突出部83的下侧面，第二吸盘30的第二上吸盘31吸住内袋82的突出部83的上侧面并且往上方移动和/或第二下吸盘32往下移动。在本实施例中，第一上吸盘21与第二上吸盘31向上移动距离为3到5cm，但不以此为限，移动的距离可依使用者需求改变。
步骤三：定位(S103)
前述步骤二后，外袋81及内袋82的开口被打开，将该第三吸盘40移动进入该内袋82内并吸住该内袋82，此时该第二吸盘30取消吸附，该第三吸盘40往该外袋81内部移动直至该内袋82的开口对齐于该外袋81的开口。由于第三吸盘40具有两斜面设计，使得在移动进入内袋82的过程中能够以较小的进入面积达到更容易进入内袋82的效果。
较佳的，在该步骤中，当第三吸盘40伸入到内袋82内后，位于第三吸盘40两侧的展开装置60地展开臂62可以在动力装置的驱动下向第三吸盘40的左右两侧展开，进而能将内袋82及外袋81开口的一端展平，使得封刀50粘合后的内袋82及外袋81更为的平整。
步骤四：接合(S104)
前述步骤三后，因封刀50与第三吸盘40集成设置在一起且封刀50位于第三吸盘40的后面，因此在第三吸盘40往该外袋81内部移动直至该内袋82的开口对齐于该外袋81的开口后，第一上吸盘21向下运动并下压封刀50。结合前述对封刀50结构的具体说明可以理解，当第一上吸盘21下压封刀50后，封刀齿54从封刀50内弹出，完成外袋81及内袋82的粘合，进入下个工序。
步骤五：出料(S105)
前述步骤四接合完成后，双层袋80形成内袋82与外袋81接合且开口切齐的状态，且接合处形成环状的连接部，而第一吸盘20及第三吸盘40取消吸附并归位，借由输送装置将双层袋80移送至收料处。
本发明已经通过上述实施例进行了说明，但应当理解的是，上述实施例只是用于举例和说明的目的，而非意在将本发明限制于所描述的实施例范围内。此外本领域技术人员可以理解的是，本发明并不局限于上述实施例，根据本发明的教导还可以做出更多种的变型和修改，这些变型和修改均落在本发明所要求保护的范围以内。本发明的保护范围由附属的权利要求书及其等效范围所界定。
