Description

预制袋包装机的物料包装方法 技术领域
本发明涉及到物料包装技术领域，尤其涉及一种预制袋包装机的物料包装方法。
背景技术
包装机代替传统人工包装，具有速度快，包装整齐美观的特点。包装机的包装物料可以是糖果、饼干、纸巾等。其中，纸巾包装机主要用于各种规格的软抽纸巾的套袋包装，纸巾包装机从大类上可以区分为：卷纸包装机，抽纸包装机，三维纸包装机，钱夹式纸包装机等。近年来，又出现了预制袋包装机，预制袋包装机广泛应用于纸巾包装，尤其适合于擦手纸、扁卷纸、卷筒纸和软抽纸，中包和大包均可。现有的预制袋包装机结构复杂，占地面积大，而且包装效率低，能耗高。现有技术中的预制袋包装物料的包装机械和工艺存在很大的问题和缺陷，具体如下：
1、推料机构需要将排列好的物料从物料排列位置处一直推送至预制袋内，物料进入预制袋内之后，推料机构还需要继续推送，将包裹好物料的预制袋推送至封口机构处对预制袋开口进行封口，然后推料机构返回，这就导致了推料机构推送物料的行程较长，推料机构运动轨迹较长。2、推料机构在推送物料时，由于推料机构的行程较长，也就导致推料机构机架较大，从而导致整机设备占地面积较大。3、推料机构在推送物料时，由于推料机构的行程较长，为了包装效率，一般会提高推料机构的推送速度，会造成推料机构与物料之间的冲击力较大，会造成物料发生倒料的情况。4、从包装效率上来讲，现有技术的预制袋包装机均是推料机构将物料和预制袋推送至封口机构处完成一个行程，然后推料机构退回至物料排列位置处进行下一物料的推送，在此过程中，物料排列位置处的物料必须等待推料机构完成一个动作行程返回才能被推送，而物料需要在排列位置处等待，造成包装效率的下降。5、从包装工位上而言，现有技术的预制袋包装机械各个工位之间行程较长、且各个工位处的工序较为复杂，如在推料机构推送物料的物料待推工位时，是与物料排列工位结合在一起的，物料既在该工位处进行排列，又在该工位处被推送，又如开袋工位既对预制袋进行开袋，物料也在该工位处入袋，这就造成了单个工位上需要完成多个动作，而在该工位处必须等待所有动作全部完成之后才能进行下一物料的动作，降低了包装效率。6、从包装效果上而言，现有的预制袋包装机械，在物料被推送至包装袋内时，物料与包装袋产生摩擦，很容易造成包装袋的损坏，尤其是针对块状物料的包装，块状物料的棱角会对预制袋的袋体发生擦挂，且物料是在推料机构的推送下进入袋体的，在推料机构的作用下，物料很容易将预制袋的袋体损坏，造成预制袋袋体破损。
公开号为CN 104129542A，公开日为2014年11月05日的中国专利文献公开了一种扁卷卫生纸的包装方法，其步骤如下：第一步，压扁：物料由输送装置输送到首次压扁机构，物料在首次压扁机构中被压扁，经过首次压扁机构压扁的物料由输送装置输送到转向装置处，物料经转向装置将两端调转，调转后的物料由输送装置输送至二次压扁机构，进行二次压扁；第二步，叠层：将经过二次压扁后的物料，通过两条侧输送机构输送至主输送机构两侧的第一推送平台和第二推送平台上，先将第一推送平台的物料推送至主输送机构上，主输送机构将物料输送至第二推送平台时停止输送，第二输送平台上的物料被推送至主输送机构上，且叠放在之前的物料之上，叠放完成后，主输送机构将叠层后的物料输送至包装平台上；第三步，推包入袋：将主输送机构输送至包装平台上的叠层后的物料，由包装平台上方的推包装置推送至吸袋开袋装置处，同时，取膜机构将包装袋从包装袋库中取出，放到送膜装置上，送膜装置将包装袋输送至吸袋开袋装置处，吸袋开袋装置将包装袋打开，物料由推包装置推入包装袋内，并推送至刀封装置处；第四步，包装封口：当物料被推包装置推送到刀封装置处时，刀封装置的上下封膜刀打开，物料被推包装置从刀封装置的上下封膜刀打开的开口处推送出去，当包装袋的开口处处在刀封装置开口处，推包装置退回，刀封装置的上下封膜刀闭合，对包装袋进行封口；第五步，反复包装：重复上述第一步到第四步，进入下一循环。该专利文献公开的扁卷卫生纸的包装方法，其中推包入袋步骤，物料先由包装平台上方的推包装置推送至吸袋开袋装置处，再通过取膜机构将包装袋从包装袋库中取出，放到送膜装置上，通过吸袋开袋装置将包装袋打开，最后物料由推包装置推入包装袋内，整个物料包装行程长，物料包装效率较低。
公开号为CN 104627394A，公开日为2015年05月20日的中国专利文献公开了一种全自动预制袋给袋式包装机，其特征在于：包括输送放袋装置、取袋装置、旋转驱动装置、开袋装置、吹气装置、辅助输送带、下料装置、成品检测装置、上封装置和成品输出装置；取袋装置位于输送放袋装置右端上方；取袋装置固定设于旋转驱动装置左端下方；旋转驱动装置驱动连接夹持装置，若干个夹持装置均匀分布 在旋转驱动装置上；开袋装置和上封装置位于旋转驱动装置中段两侧；吹气装置固定设于开袋装置右侧上端；下料装置和成品检测装置位于旋转驱动装置右端，成品检测装置位于下料装置左侧；辅助输送带位于旋转驱动装置右端，辅助输送带位于下料装置下方；成品输出装置位于旋转驱动装置左端。该专利文献公开的全自动预制袋给袋式包装机，其中夹持装置夹持袋子与物料输送是单独动作的，物料包装行程长，物料输送包装效率低，此外，占地空间也较大。
公开号为CN 201989972U，公开日为2011年09月28日的中国专利文献公开了一种预制袋自动装袋包装机，包括机架、电动控制箱、链条推杆输送装置和封口装置，其特征在于：所述预制袋自动装袋包装机还包括自动供应预制袋装置，所述封口装置设置在链条推杆输送装置和自动供应预制袋装置之间，所述自动供应预制袋装置包括装载腔体、送袋气缸、上袋气缸、进撑气缸、压袋气缸和撑袋气缸，上袋气缸竖直设置在装载腔体的下方且与装载腔体连接，在装载腔体的两侧壁的外侧分别设有一个下吸嘴气缸且两个下吸嘴气缸相对设置，每一个下吸嘴气缸与一个下吸嘴连接，两个下吸嘴位于装载腔体的两侧壁的内侧，在装载腔体的上方设有两套互成角度的进撑气缸，在两进撑气缸之间设有限位气缸，撑袋气缸与两套互成角度的进撑气缸的后侧部连接，送袋气缸与撑袋气缸连接，在两套互成角度的进撑气缸与装载腔体之间设有采用真空进行吸取的上吸嘴，上吸嘴的前侧部设有撑板，压袋气缸设置在装载腔体的前侧。该专利文献公开的预制袋自动装袋包装机，通过装载腔体、送袋气缸、上袋气缸、进撑气缸、压袋气缸和撑袋气缸的相互配合对袋子进行张袋，各气缸动作配合要求严格，张袋效率低，物料包装行程长，而且维护成本高。
综上所述，现有技术中的预制袋包装机存在推料行程长、机器设备占地面积较大、物料不规整容易倒料、预制袋破袋、各工位处包装工序较多、包装效率低等问题。

二十一、本发明，张袋板由前端张板、中端张板和后端张板一体成型而成，前端张板为竖直板，竖直板的角为圆角，预制袋在完全张开前，首先通过前端张板接触预制袋，将前端张板的角设置呈圆角，较小了棱线，通过圆角过渡，减小预制袋底部所受冲击，能够防止预制袋底部被戳坏，保障预制袋完好。
二十二、本发明，中端张板的横截面呈“U”字型，整个张袋板与预制袋接触面积最大的是中端张板，通过将中端张板设置成“U”字状，中端张板的外壁与预制袋内壁接触时，实现了良好的圆弧过渡，利于实现预制袋被完好的张开，没有破损。
二十三、本发明，后端张板为倾斜板，后端张板的顶部高于中端张板的顶部，后端张板采用倾斜设置，能够防止整个张袋板没入预制袋中，当物料被装入到张开的预制袋后，张袋板更易脱离预制袋，不易造成预制袋口褶皱，从而利于提高物料包装工整度。
