Description

[0001] The present invention relates to a roll centering device,

The present invention maximizes the supply quality of the fabric by matching the center of the fabric supplied to the fabric take-up roll, such as a cardboard for manufacturing corrugated cardboard, to the center of the supply line, and more specifically, And more particularly, to a center adjusting device for a cloth winding roll which is capable of precisely detecting the center of a wound roll of the roll and feeding the roll at an accurate position.

Generally, a joint such as corrugated cardboard is formed by attaching three or more kinds of paper or paperboard to each other to increase the buffering, keeping warm or durability according to the deformation state. The fabric is formed by adhering the cloth to each other with an adhesive or a heat- It is called corrugated fabric.

The corrugated cardboard is widely used as a packaging material. It is made of a double wall corrugated cardboard (double wall) or a double wall corrugated cardboard (double wall) depending on the use and environment of use. In some cases, In some cases,

On the other hand, the corrugated cardboard is manufactured by loosening a raw paper (fabric) in a roll form and sending it to a bone forming machine to form a bone, and then feeding a new roll of raw paper to one side of the formed bone, a double faced web or a double faced web including a process of attaching a backing sheet to another side of the single side web or a process of adding another type of single side fabric and then adhering the backing sheet, (Mask) manufacturing process, and the corrugated cardboard fabric is made only through these two processes.

In the latter two processes, when one side or both sides of one side and the other side are fed side by side on the other side in order to become the corrugated cardboard fabric, the input positions of the respective fabrics or sheets must be uniformly aligned so that the loss And the productivity and quality are different according to the sorting method. The apparatus for processing this process is referred to as a double facer (double facer) and a thermal bonding method is used.

Examples of the material of the bonding paper include all kinds of paper and plastic films such as polarizing paper, glazinc paper, white paper, kraft paper and cardboard; films such as cellophane, vinyl chloride, polyethylene and polypropylene; metals such as aluminum and iron plate; It can be used for fabrics such as fabrics.

The reason why the paper is subjected to multiple bonding and processing as described above is to increase the thickness and strength, and to increase the impact resistance and strength, such as corrugated cardboard. Such a bonding area may be a packaging box, a beverage container such as milk or juice, And the like.

Such a laminator for bonding multiple fabrics can be fabricated by supplying the fabrics as disclosed in Korean Patent Application No. 10-2008-0039292 (entitled " Alignment Device for Multiple Fabric Joining and Method Therefor, Apr. 28, 2008) An aligning unit for aligning the raw material supplied from the raw material supplying unit, and a joint unit for joining the raw materials aligned by the aligning unit.

The aligning unit aligns the single-side fabric fed from the single-sided producing unit of the raw-material supplying unit and is related to the present invention.

The joining portions are bonded to each other while heating them at a temperature at which the adhesive is heated to a temperature at which the single-sided fabric and the backing paper are preheated by the preheater and supplied to the ends of the formed corrugated paste.

The adhesive is an adhesive composed of a starch component. When the adhesive is heated in a molten state, the adhesive is viscous. As a result, when the adhesive is heated at the end of the bone as described above, the adhesive is viscous and adhered to the backsheet.

The corrugated board formed by the joining portion is stacked by the stacker after passing through a width dividing device and a cutter for cutting the length, forming a folding line at a pre-designed position.

For this purpose, the aligner aligns the positions of the one side faces inserted into the joining portion with respect to the center line or side edge of each one side face fabric.

The aligning unit is provided with a guide plate so as to be in contact with both ends of the fabric at a position where the one-side fabric passes, and aligning and aligning the entrance position of the fabric while moving the guide plate laterally as the fabric passes .

That is, the pair of guide plates capable of adjusting the lateral movement can be provided on both sides of the entry path on which the fabric enters, and the fabric is supplied between the guide plates so that the side ends of the advancing fabric are forcedly aligned by the guide plates And moves to the adapter.
