Description

Detailed Description of the Invention

Industrial application fields

  The present invention relates to a corrugated board manufacturing apparatus.

Corrugated cardboard sheets are manufactured continuously while splicing the base paper with a splicer. Currently, double-sided adhesive tape is used to join the base paper. In many cases, it is bonded with double-sided adhesive tape using aluminum, and the sheet containing the part joined after rolling is detected with a metal detection sensor and discharged with a defect removal device so that it does not enter the product. May become a complaint. If the double-sided adhesive tape has a large volume, the amount of waste is reduced. However, considering the convenience of workers, it is as short as 50m.
Usually, there are many corrugators that can produce double-sided corrugated cardboard. Recently, paper is frequently changed in small lots, and the amount used is considerably large. Also, several types of double-sided adhesive tapes with different performances are used depending on the type of paper. By the way, the double-sided pressure-sensitive adhesive tape is used after peeling off the release paper, but becomes waste together with the paper tube. In addition, the defective sheet containing the double-sided adhesive tape dropped by the defect removing apparatus is crushed and repeatedly recycled to the corrugated base paper.

Problems to be solved by the invention

  Since screen adhesive tape is used to bond the base paper, release paper that becomes waste, paper foil, and aluminum foil with adhesive material are generated. These are not enough to be recycled in one factory, but halfway. At present, they are discarded without being recycled due to technical and cost problems. In addition, the tape application work is very difficult to automate and is performed manually by the workers. By automatically applying an adhesive having an adhesive performance equal to or better than that of the double-sided pressure-sensitive adhesive tape with the non-contact type applicator 1 and adhering the base paper, waste can be eliminated, the environmental load can be reduced, and labor saving and cost reduction can be simultaneously performed.

Means for solving the problem

  A non-contact type automatic coating device that does not use metal double-sided adhesive tape that is difficult to recycle, is difficult to automate, and does not use high-cost metal-based double-sided adhesive tape. Thought. FIG. 1 shows a conceptual diagram. The control panel 6 receives an adhesive application start signal from the production management device, starts the traverser 2, detects the width of the base paper 5 by the sensor 3, and uses the non-contact type applicator 1. The adhesive 4 is applied in a bead shape by a pressure type supply device.

Action

  If an adhesive that does not interfere with paper recycling is used, almost no waste is generated, so the amount of waste is reduced and the environmental load can be reduced. In addition, automation can be achieved and the workload of workers can be reduced. In addition, the adhesive is cheaper than the double-sided adhesive tape, and the waste disposal cost is almost eliminated, thereby reducing the cost.

Example 1
An example of using this apparatus is shown in which splicing of corrugated cardboard paper is performed in a splicer in order to continuously manufacture corrugated cardboard sheets without decelerating. Actually, while the base paper is being unwound on one base paper hook, preparation for paper splicing is made on the other side, so one splicer and two base paper hooking devices are a set. Although not shown, two applicators are alternately controlled on one surface of the control panel 6. When the adhesive application start signal of the production management device is input to the control panel 6, the traverser 2 using the air-driven rodless cylinder attached to the splice unit (7) starts and starts moving from the end, and the sensor 3 After the end of the base paper 5 is detected, the applicator 1 starts supplying adhesive in a plurality of rows of beads through a pressure line of the adhesive, and after detecting the other end, a predetermined position before the end of the base paper is detected. Complete the supply at the location. At the time of splicing, the base papers are pressed against each other and the bead-like adhesive is spread to secure a bonding area and at the same time adhere.

The invention's effect

  Waste generation is almost eliminated and environmental impact is reduced, and automation can be achieved. Although initial investment is required, the cost of expensive double-sided adhesive tape is reduced, and costs can be reduced in the long run.

  It is a conceptual diagram of this invention.
