Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for supplying a thread-like material or tape-like material to be bonded to a veneer veneer or a corrugated pole for the purpose of connection or reinforcement.

(b) Prior art In the past, in the process of reeling a veneer veneer peeled off from logs using a rotary race, adhesive tape was attached to both sides of the veneer, and adhesive tape was applied while the narrow veneer was intermittently transferred. The liner and the core paper are interposed with adhesive tape and bonded by polymerization during the manufacturing process of the one-stage pole. were all supplied by hand by workers.

(c) The problem that the invention seeks to solve.

It is extremely dangerous if the known tape or yarn etc. is applied while the adhesive material, veneer veneer or cardboard base paper, is being transferred, so the manufacturing equipment must be stopped, and each time the yarn, etc. runs out, it is extremely dangerous. The work was interrupted every time and the work was supplied, resulting in a decrease in work efficiency.

Moreover, the work is difficult because the area for supplying the yarn etc. is narrow.

(D) Means for Solving the Problems The present invention aims at directing the blowing part of the conductive gas toward the material to be bonded The aforementioned problems were solved by introducing the tip side of the elongated material into a jet stream ejected from the jet air flow and causing the elongated material to reach the adhered material X by the jet stream.

(E) The working gas is set so that its ejection part is directed toward the moving path of the veneer veneer or corrugated pole base paper, and compressed air is sent into the gas by a compressor, and at the same time, adhesive tape or thread is introduced into the gas conductor. Then, the threads, etc. ride on the jet stream ejected from the spouting part and reach the veneer veneer or cardboard base paper to which it is to be bonded, and are caught in the veneer reeling process, and are caught in the corrugated pole manufacturing process. It is sandwiched between the liner and core paper and adhered to each other.

(F) Example An example of the present invention will be explained with reference to the drawings. One of the adhesive-attached elongated materials 1 used in the present invention is, for example, an adhesive in which an adhesive is added to substantially untwisted yarn. Thread 1a, or adhesive thread 1b made into a tape by passing the adhesive thread 1a under pressure with a pair of rollers, and a plurality of thin threads that are not substantially twisted when young are aligned and an adhesive is added. A yarn IC such as adhesive yarn made into a tape shape,
These threads 1a to 1c are suitable for making narrow veneer veneers horizontally or reinforcing corrugated poles, and are also suitable for applying re-adhesive adhesive 1d on one side and template agent on the other side. The paper tape 1e that has been wound up and the composite tape 2 in which the threads 1a, lb or IC are attached to the adhesive ld side of the paper tape 1e are attached to both sides of a band-shaped veneer veneer that is peeled off from the rotary race. Suitable for use in gluing and preventing cracking during the drying process, the adhesive may be a solvent-based adhesive (the solvent contains water), a thermoplastic adhesive, a chemically reactive adhesive, an animal or plant-based adhesive, or Regarding adhesives, etc., a rewetting adhesive was used as the adhesive attached to the paper tape in this example, and a thermoplastic adhesive was used as the adhesive attached to the thread 1axlc.

Next, we will explain how to supply the above-mentioned elongated material l to the rolled up part in the gluing process of the veneer veneer 3 or to the polymerized adhesive part in the step pole manufacturing process. It shows the process of reeling the strip-shaped veneer veneer 3 that is peeled off,
The elongated material 1 is supplied to the left and right sides of the winding part of the rolled ball supported by the reeling device 6, and is rolled up, and the rolled ball is transferred to the dryer.

FIG. 2 shows a method of supplying elongated material to the corner or middle part of a box in the corrugated board manufacturing process, in which the back liner 7 is supplied from one side to the press roll 8, and the core raw paper 9 is supplied from one side to the press roll 8.
are sequentially wound around a pair of interlocking corrugating rolls 10 and 10 to form a tier, and adhesive is applied to the lower top portion of the tier using an applicator roll 11 and then adhered to the back liner 7.

The single-sided corrugated board A obtained in this way is guided to the rider roll 13, adhesive is applied to the protruding part of the lower surface of the center core 15 of the single-sided corrugated pole A by the applicator roll 1B, and a corrugating belt is applied to the lower side of the adhesive. 17, and the heating part 18 is placed in the front and the cooling part 20 is placed in the rear.
19 is the starting end of the full gating belt 17 and the heating section 18
In supplying the starting end of the corrugated pole box, a plurality of the elongated materials 1 are supplied from the front side of their polymerized bonded parts, and the supply position is the part that becomes the horizontal ruled line of the corrugated pole box (the vertical ruled line of the box). or corrugated pole boxes for storing heavy products, etc., which require reinforcement depending on the purpose of use, such as the middle part or other appropriate parts.

Next, to explain the method of supplying the elongated material L, Fig. 3 shows an example of a feeding device, in which the material to be bonded X is a plywood veneer 3 that is rolled up in the reeling process, and A single-sided corrugated pole A and a front liner 19 are used, and the supply section Y is a winding part in the former case, and an overlapping part of the single-sided corrugated pole A and the front liner 19 in the latter case.

A gate-shaped frame 21 is installed in front of the supply section Y.

A guide rod 23 is fixed to 2 and 22, and a support rod 25 parallel to the guide rod 23 is slidably supported, and a plurality of gas conductors 26 and e are attached to the support rod 25 at appropriate intervals via a mounting frame 27. The support rod 25 can be moved laterally by operating an air cylinder or a motor under automatic control, thereby adjusting the position of the gas conductor 2B, and the mounting frame 27 can be moved with respect to the support rod 25. If slidably mounted, the movement of the individual gas conductors 26 can be adjusted manually or by automatic control. At that time, conductive gas 2B
When the pipe is constructed of a pipe and the elongated material l is supplied from different directions, the middle part should have a double structure that can be expanded and slid.

The gas guide 26 is provided with an air supply pipe 26 whose base communicates with the compressor. When the gas guide 26 is constructed of a pipe 26a or a flexible hose as shown in FIG. 4, the tip of the air supply pipe 26 is It is inserted diagonally into the pipe 26a and bent in the direction of air introduction. At that time, if a return air supply pipe 31a is also attached as shown in FIG.

FIG. 6 shows another embodiment of the gas conductor 2B,
This gas guide 26 is configured in the shape of a gutter, with its tip oriented toward the supply section Y, and the air supply pipe 26 facing the groove obliquely from above so that the jet stream flows in a fixed direction.

If the place where the elongated material 1 is supplied to the gas conductor 26 (the place where the feeding device is installed) is directly above or directly below the material to be bonded X, the feeding operation will be difficult and dangerous. It is preferable to supply the material X from the side of the transfer line, and as shown in FIG. In the case where the air supply pipe 26 for transfer is attached to the side and the middle part, and the bent part is bent, the resistance at the bent part due to the elongated material 1 is large and the inside corner side will wear out. An opening is provided in the casing, and a curved ceramic piece roller 32 with excellent abrasion resistance is provided which is internally supported in the casing, or an intake hole or compressed air is actively ejected toward the inside. good.

In addition, when guiding the elongated material l to the supply section Y through a bending path, if it is to be carried out manually at the start of supply, the plurality of guide pipes 33-. should all be made straight as shown in FIG. A trachea 26... is attached, and a ceramic roller 34110 is provided at the entrance.

Furthermore, the supply method shown in FIG. 7 is suitable when the space on the side of the transfer line is narrow, and if there is some extra space, the supply method shown in FIG.

When adhering, a plurality of gas conductors 26φ are attached to − number of mounting frames 27.

In the apparatus shown in FIG. 10(a), when a plurality of gas conductors 26 are arranged in parallel, the diameter of the pipe constituting the gas conductors 26 is Since they are constant, it is impossible to make them narrower than when they are in contact with each other. Therefore, the guide plate 29 having a plurality of guide holes 29a is placed at position a when feeding the elongated material, and moved to position a'' after the feeding is completed. When the elongated members 1 are rotated as shown by the chain lines in FIG. 10(b), the distance between the elongated members 1 in plan view can be narrowed.
