A laminated paperboard-like packaging material in the form of a laminated paperboard material (10) comprises a non-solid core of lightweight material having regular polygons in the form of hexagonal open-ended cells (14) defined by walls (16), the core being cemented between lightweight outer sheets of laminate material (18), the core itself being flexurally deformable. The core (12) and outer laminate (14) are laminated to form a laminated paperboard (10) having improved strength and resistance to bending in all planar directions, particularly in mutually perpendicular directions as indicated by axes (20 and 22), to bending in the direction indicated by arrow (24). The strength imparted to the laminate (10) by the core (12) is due at least in large part to the effect of the core pattern, by which the laminated paperboard can be made from lightweight materials.

Description

层压纸板类纸板材料及其制造方法和设备Laminated cardboard-like cardboard material and its manufacturing method and equipment

本发明涉及一种层压纸板类材料及其制造方法和制造设备。The invention relates to a laminated cardboard-like material and its manufacturing method and manufacturing equipment.

这类纸板类包装材料是公知的。瓦楞纸板作为包装材料得到非常广泛的应用。包装箱就是用这种纸板制成的。通常这种材料的板芯成瓦楞状被粘合层压在外层压纸之间。作为包装材料必须重量很轻，但强度很高。虽然通常的瓦楞纸板类的包装材料的重量很轻，但其缺点在于其增强方向垂直于瓦楞方向，所以瓦楞方向并没有得到增强，致使在瓦楞方向易于弯折或换句话说易于变形。Such cardboard-like packaging materials are well known. Corrugated cardboard is widely used as packaging material. The packing box is made of this kind of cardboard. Typically the core of this material is corrugated and adhesive laminated between outer laminates. As a packaging material it must be light in weight but high in strength. Although the usual corrugated cardboard packaging materials are light in weight, their disadvantage is that their reinforcing direction is perpendicular to the corrugated direction, so the corrugated direction is not strengthened, so that it is easy to bend or in other words easily deformed in the corrugated direction.

本发明的目的在于提出一种可耐在任何平面方向弯折的包装用纸板材料。The object of the present invention is to propose a cardboard material for packaging which can withstand bending in any plane direction.

下面将结合附图举例对本发明加以说明。图中示出：The present invention will be described below with examples in conjunction with the accompanying drawings. The figure shows:

图1示出本发明的层压纸板材料形式的层压纸板类包装材料10。Figure 1 shows a laminated paperboard-like packaging material 10 in the form of a laminated paperboard material according to the invention.

层压纸板10包括一由轻质材料构成的非实心的芯12，该芯成在室壁16之间形成的六角形的端面开口的室14形式的有规律的多边形，粘合固定在两相对的薄的轻质的外层压材料纸18之间。尽管外层压材料纸18本身将受到弯曲变形的作用，但由其组合成的层压纸板10将对其进行增强，从而使其基本耐所有平面方向，尤其是在两个相互垂直的轴线20和22所示的方向的弯折；因而可以耐箭头24所示的弯折作用。The laminated paperboard 10 comprises a non-solid core 12 of lightweight material in the form of a regular polygon in the form of a hexagonal open-ended chamber 14 formed between chamber walls 16, adhesively secured between opposite sides of the chamber. Between the thin lightweight outer laminate paper 18. Although the outer laminate paper 18 itself will be subject to bending deformation, the laminated paperboard 10 from which it is combined will reinforce it so that it is substantially resistant in all planar directions, especially in the two mutually perpendicular axes 20 Bending in the directions shown in and 22; thus can withstand the bending action shown in arrow 24.

通过芯12实现的层压板10的强度是芯的图形的作用所致，由于具有该图形，因而可以采用轻质材料制造层压纸板材料。该芯一般由槽纹型材料构成，其平方米克数为125g/m2。The strength of the laminate 10 achieved by the core 12 is due to the effect of the pattern of the core, thanks to which it is possible to manufacture the laminated paperboard material from lightweight materials. The core is generally constructed of fluted material having a grammage of 125 g/m 2 .

外层压材料纸18也是由轻质材料构成，一般由牛皮纸覆层材料构成，并且其平方米克数为150 g/m2。The outer laminate paper 18 is also constructed of a lightweight material, typically a kraft overlay material, and has a grammage of 150 g/ m2 .

当层压纸板10作为包装材料采用时，层压板必须具有必要的薄度，以便可以用层压板或多块层压板10采用传统的方式相互固定在一起制成很轻并且不笨重的容器等。就此点而言，其厚度应在1至10mm之间，优选在2至5mm之间。作为纸板包装材料的典型值，层压纸板10的平方米克数为500g/m2。When laminated paperboard 10 is used as packaging material, the laminate must have the necessary thinness so that light and not bulky containers and the like can be made from the laminate or multiple laminates 10 secured to each other in conventional manner. In this regard, its thickness should be between 1 and 10 mm, preferably between 2 and 5 mm. As a typical value for paperboard packaging materials, the laminated paperboard 10 has a grammage of 500 g/m 2 .

制造层压板10的工艺涉及对芯材的预制。如图2和3所示，制造芯12的方法涉及利用通过沿每层纸26主要表面形成的偏置的粘接带30实现的相宜交错平行的固定区，将多个构成芯的纸26相互粘接成层叠28。如图2(a)所示，粘接带30沿交替的层26相互偏置。图2(a)示出构成层叠28前的情况，而图2(b)强调示出构成层叠28的情况。为保证形成的室14为有规律的六角形，粘接带30具有相同的宽度，沿交替的纸层26偏移粘接带30间隔距离的一半。如果需要另一种室形状，宜对粘接带30和间隔进行相应的改变。The process of making laminate 10 involves prefabrication of the core material. As shown in Figures 2 and 3, the method of making the core 12 involves bonding a plurality of papers 26 constituting the core to each other using suitably staggered parallel fastening zones achieved by offset adhesive strips 30 formed along the major surfaces of each ply of paper 26. Bonded to form a stack 28 . As shown in FIG. 2( a ), the adhesive strips 30 are offset from each other along alternating layers 26 . FIG. 2( a ) shows the situation before forming the stack 28 , while FIG. 2( b ) highlights the situation after forming the stack 28 . To ensure that the cells 14 are formed in a regular hexagonal shape, the adhesive strips 30 have the same width, offset along the alternating paper layers 26 by half the distance between the adhesive strips 30 . If another chamber shape is desired, the adhesive strip 30 and spacing should be changed accordingly.

而且不仅限于此方法，采用如图3所示的设备，可以很容易地沿纸层26形成粘接带30。设备32包括一个在两个侧部分之间的机架34，在该机架上旋转安装有一个压送辊36、多个粘接剂涂布辊和输送辊40。由电机42对辊40进行驱动，同时辊36和38由辊40通过啮合链轮44驱动。一旦设备投入使用，则辊32滚动过容纳有粘接剂液体的溜槽。And not limited to this method, the adhesive tape 30 can be easily formed along the paper layer 26 by using the equipment shown in FIG. 3 . The apparatus 32 includes a frame 34 between two side sections on which a nip roll 36, adhesive applicator rolls and delivery rolls 40 are rotatably mounted. Roller 40 is driven by motor 42 , while rollers 36 and 38 are driven by roller 40 through intermeshing sprockets 44 . Once the apparatus is in use, the rollers 32 roll through a chute containing the adhesive liquid.

通过沿在压送辊36与涂布辊38之间的辊隙36.1对连续的纸的轧压实现在纸26上的粘接剂的涂布。连续的纸26以所需的横向间隔沿设备32被交替横向偏移轧压，从而实现如上所述的粘接带30的所需的偏移涂布。Application of the adhesive on the paper 26 is effected by nibbling the continuous paper along the nip 36 . 1 between the nip roll 36 and the applicator roll 38 . The continuous web 26 is alternately laterally offset calendered along apparatus 32 at desired lateral intervals to achieve the desired offset coating of adhesive tape 30 as described above.

如图2(b)所示，因此连续的纸26通过粘接带30的粘合作用相互粘合固定，形成层叠。As shown in FIG. 2(b), the continuous papers 26 are thus bonded and fixed to each other by the adhesive action of the adhesive tape 30 to form a laminate.

在下一个步骤中形成芯12，并且在图2(c)中示出顺进入图2(b)的方向的层叠，如图2(c)所示采用铡刀式剪切机等(图中未示出)通过对层叠的剪切将端部分46与层叠分离。端部分46的厚度主要决定层压纸板10的宽度，这是由于其一旦展开，将形成芯，该端部分46短于10mm，优选为2至5mm，从而实现所需的层压纸板的宽度。将层叠28对齐，以便实现多个芯基，所述芯基被展开形成芯12。甚至可以通过同时对层叠28的裁切，形成多个芯基。The core 12 is formed in the next step, and the lamination along the direction into FIG. 2( b) is shown in FIG. 2( c), using guillotine shears etc. OUT) the end portion 46 is separated from the stack by shearing the stack. The thickness of the end portion 46 primarily determines the width of the laminated paperboard 10 since it will form the core once unrolled, being shorter than 10 mm, preferably 2 to 5 mm, to achieve the desired laminated paperboard width. The stacks 28 are aligned so as to achieve a plurality of core bases which are unfolded to form the core 12 . It is even possible to form multiple core bases by simultaneously cutting the laminate 28 .

如图2(c)和2(d)所示，形成芯12的最后步骤涉及简单的将由层叠28上切割下来的芯基29按箭头48所示方向的展开，形成六角形室物件。为实现此效果，纸26由一种坚固的但可弯曲的材料构成，因而由层叠上切割下来的条带可以进行必要的变形，形成晶格状的芯12。As shown in Figures 2(c) and 2(d), the final step in forming the core 12 involves simply unfolding the core base 29 cut from the laminate 28 in the direction indicated by arrow 48 to form a hexagonal cell object. To achieve this effect, the paper 26 is formed of a strong but bendable material so that strips cut from the stack can undergo the necessary deformation to form the core 12 in the form of a lattice.

一旦制成芯12后，则制造层压板10的最后步骤涉及的是将其尺寸相互配合的外层压纸18简单的与芯12的两个相反侧的粘接固定。可以采用任何一种相宜的粘接剂将外层压材料纸18粘合固定在芯12上并将板层26相互粘接固定并可将纸层26相互粘接。在南非作为公知的粘接剂是克瓦尔化学有限公司生产的商品名为QAR 173A的聚醋酸乙烯树脂乳液。Once the core 12 is formed, the final steps in the manufacture of the laminate 10 involve the simple adhesive attachment of the outer laminate paper 18 , sized to match, to opposite sides of the core 12 . Any suitable adhesive may be used to adhesively secure the outer laminate paper 18 to the core 12 and to bond the plies 26 to each other and the paper layers 26 to each other. In South Africa, as known bonding agent is the polyvinyl acetate resin emulsion of trade name QAR 173A produced by Keval Chemical Co., Ltd.

虽然可以分别制作板层10，但应看到，这种过程将耗费大量的时间。While the plies 10 could be fabricated separately, it will be appreciated that such a process would be time consuming.

图4示出用于连续制造层压纸板10包装材料的设备50。作为通常制造层压板材料的设备50，除了特殊的说明外，一般具有两个外层压纸材料供给卷筒52和芯馈送、预处理和干燥/硬化设备54。设备54包括一芯供给架，在芯供给架上储存有上述结合图2和3所述制成的并粘合固定的折叠的尚未展开的芯基。芯供给架通常是弹簧承载的，从而可以保证一旦设备投入使用易于实现芯的供给。FIG. 4 shows an apparatus 50 for the continuous manufacture of laminated paperboard 10 packaging material. As an apparatus 50 for making laminated board material in general, there are generally two outer laminated paper stock supply rolls 52 and a core feeding, pre-treating and drying/hardening apparatus 54 unless otherwise specified. Apparatus 54 includes a core supply rack on which are stored folded, yet unfolded, core bases formed and adhesively secured as described above in connection with FIGS. 2 and 3 . The core supply rack is usually spring loaded to ensure easy core supply once the equipment is in service.

设备50包括一外层压纸预处理单元60和连续干燥和硬化站62、一轧压和层压站64、一层压纸板旋裁转切单元66和一存储架68。The apparatus 50 includes an outer laminate paper pretreatment unit 60 and continuous drying and curing station 62 , a calendering and lamination station 64 , a laminated paperboard rotary cutting unit 66 and a storage rack 68 .

使用时，卷筒52与芯供给架56同步，从而实现芯材料70和外层压材料纸72向层压站64的供给。一旦两相对的外层压纸由卷筒52拉出，首先通过单元60，在该单元一般通过涂布、印刷和/或任何标准包装材料的预处理等处理，同时通过相应的导辊和处理辊组74。这时材料72到达干燥和硬化站62，在该站在材料通过导辊和处理辊组76的同时，对其以通常的包装处理方式进行干燥和硬化。此时，材料72通过导辊组78被馈送给层压站。In use, the roll 52 is synchronized with the core supply rack 56 to effectuate the supply of core material 70 and outer laminate material paper 72 to the lamination station 64 . Once the two opposing outer laminated papers are drawn from the roll 52, they first pass through the unit 60 where they are typically treated by coating, printing and/or pre-treatment of any standard packaging material, while passing through corresponding guide rollers and processing Roll set 74. The material 72 then reaches the drying and curing station 62 where it is dried and cured in the usual packaging handling manner as it passes through the set of guide and handling rollers 76 . At this point, the material 72 is fed to the lamination station by means of guide roller sets 78 .

与材料72的供给同步，芯材料70被由芯供给架56提取出。如图2和3所示，为实现芯材料70的连续的供给，由层叠28上切割下来的各个芯基如图2(d)所示端头沿端面35对齐，相互粘合固定，并且堆叠在架上的芯因此形成连续的长度并且基本处于未展开状态，但在折叠弯曲处略有展开除外。因此芯材料70通过芯材料递送辊80并沿展开和固定压送辊组82被前送，在此处芯基被相应展开成图2(d)所示的晶格状。这时在站64处，对外层压纸材料72的相应的面或芯材料70相对的棱上或两者上涂布粘接剂，外层压纸材料72和芯材料70被层压并被轧压在一起。其中必须对压力的大小进行控制，以便保证芯材料在处理过程中不被损坏。Synchronously with the supply of material 72 , core material 70 is withdrawn from core supply rack 56 . As shown in Figures 2 and 3, in order to realize the continuous supply of the core material 70, the ends of the core bases cut from the stack 28 are aligned along the end faces 35 as shown in Figure 2 (d), bonded and fixed to each other, and stacked The core on the shelf thus forms a continuous length and is substantially in an unfolded condition, except for a slight unfolding at the bends of the folds. The core material 70 is thus fed through the core material delivery rolls 80 and along the set of unrolling and fixed nip rolls 82 where the core base is accordingly unrolled into the lattice as shown in Figure 2(d). Now at station 64, adhesive is applied to the respective faces of the outer laminate paper material 72 or the opposing edges of the core material 70, or both, and the outer laminate paper material 72 and core material 70 are laminated and bonded. Rolled together. The magnitude of the pressure must be controlled in order to ensure that the core material is not damaged during handling.

利用输送机86对层压纸板材料84进行输送，输送过程中实现层压板材料84的干燥和硬化，层压纸板材料84被输送至裁切单元66，在此处对连续的层压纸板进行处理，使制之变成包装纸板类产品，例如纸板半成品，并到达堆叠站88，在该站被裁切好的单块层压板10被存储在存储架68上。另外也可以直接对层压纸板进行进一步的涂布和处理。The laminated cardboard material 84 is transported by a conveyor 86, during which the laminated cardboard material 84 is dried and hardened, and the laminated cardboard material 84 is transported to the cutting unit 66, where the continuous laminated cardboard is processed , so that it becomes a packaging cardboard product, such as a cardboard semi-finished product, and arrives at the stacking station 88, where the individual laminated panels 10 that have been cut are stored on the storage rack 68 at this station. In addition, further coating and treatment can be carried out directly on the laminated paperboard.

上面对本发明的优点作了专门的表述，即本发明提出了一种主要用于包装的层压纸板材料，但显然也并不排除其它的应用。The advantages of the invention have been specifically stated above, namely that the invention proposes a laminated paperboard material mainly for packaging, although other applications are obviously not excluded.
