Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative plywood production for manufacturing a decorative plywood by laminating a core material and a surface material with a two-component mixed type adhesive consisting of a main agent and a curing accelerator. Regarding the device.

[0002]

2. Description of the Related Art Generally, a decorative plywood used as a face material for a system kitchen or the like is manufactured by laminating a surface layer material such as a melanin decorative board on the surface of a core material such as a particle board. In particular, as the adhesive used for bonding the core material and the surface layer material, in order to shorten the curing time, a so-called two-liquid mixing type in which a main agent and a curing accelerator are mixed is applied. Sometimes.

Conventionally, as shown in FIG. 7, the manufacture of a decorative plywood using such a two-component mixed type adhesive has generally been done manually.

That is, first, as shown in FIG.
The core material P is inserted into the adhesive application device a and the main agent is applied to the adhesive surface. On the other hand, the surface layer material Q has a curing accelerator applied to its adhesive surface by using a brush or the like. Then, the surface layer material Q is loaded into a drying oven using a far infrared heater (not shown) and the curing accelerator is dried to some extent and then taken out. This is because when the curing accelerator is dried to some extent, a larger adhesive strength can be obtained. Next, as shown in FIG. 2B, the adhesive surface of the core material P coated with the main agent and the adhesive surface of the surface layer material coated with the curing accelerator are placed facing each other. Subsequently, as shown in FIG. 3C, these P and Q are set in a press machine b, and the core material P and the surface layer material Q are pressed to form a decorative plywood.

As shown in FIG. 8, in the adhesive applying device a, the doctor roll 102 is arranged close to the lateral side of the applying roll 100, and the feed roll 104 is arranged just below the applying roll 100. Has been done. Then, while the core material P is being transferred by the feed roll 104, the coating roll 1
No. 00 and the doctor roll 102, the main agent is continuously applied to the upper surface of the core material P through the gap between the application roll 100 and the doctor roll 102, and the main agent adhered on the application roll 100. In this case, the amount of the main agent applied to the core P is adjusted by changing the gap between the application roll 100 and the doctor roll 102.

[0006]

As described above, in the production of the conventional decorative plywood, the core material P for the adhesive applying device a is formed.
Insertion work, work to overlap the core material P and the surface material Q,
Since the setting work and the like on the press machine after the superposition of both P and Q are all performed manually, a large amount of manpower is required and mass productivity is insufficient. In addition, when the core material P and the surface layer material Q are superposed on each other, a defect such as a positional deviation between the core material P and the surface layer material Q is likely to occur, and there is a problem that the product yield of the decorative plywood is poor.

Further, an adhesive material applying device a having the structure shown in FIG.
In the above, since the base material applied to the core material P has a relatively high viscosity, when the core material P is not interposed between the application roll 100 and the feed roll 104, the base material attached to the application roll 100 is It does not drip onto the feed roll 104 within a short time.

On the other hand, when an attempt is made to apply the curing accelerator to the surface layer material Q using the adhesive application device a having the same construction as that shown in FIG. 8, the following problem will occur. That is, the surface material Q
The viscosity of the curing accelerator applied to the coating material is much lower than that of the base material. Therefore, when the surface layer material Q is not present between the coating roll 100 and the feed roll 104, the curing accelerator adhered on the coating roll 100. Feed roll 10 within a short time
It drips on top of 4. Further, if the surface layer material Q is thin, the gap between the coating roll 100 and the feed roll 104 is also small. Therefore, when the surface layer material Q is not present between the two rolls 100, 104, it adheres to the coating roll 100. The curing accelerator existing on the transfer roll 104 easily gets over the feed roll 104. Therefore, when the next surface layer material Q is transferred by the feed roll 104, there occurs a problem that the curing accelerator is also applied to the lower surface of the surface layer material Q.

Under these circumstances, in order to apply the low-viscosity curing accelerator to the surface layer material Q, the adhesive applying device a having the structure shown in FIG. 8 cannot be used as it is. I had no choice but to resort to manual work using a brush or the like. Therefore, the coating work requires an excessive amount of labor.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to easily apply a main agent to a core material and a curing accelerator to a surface layer material with a small amount of manpower, and It is an object to improve the product yield of decorative plywood by reducing the incidence of defective products while improving productivity by minimizing the number of steps when manufacturing a decorative plywood by bonding with a surface layer material. To do.

[0011]

The present invention adopts the following constitution in order to solve the above problems.

That is, in the apparatus for manufacturing a decorative plywood according to the present invention, a main agent applying equipment for applying a main agent to the adhesive surface of the core material, a curing accelerator applying equipment for applying a curing accelerator to the adhesive surface of the surface layer material, At least one of the drying equipment for drying the curing accelerator applied in the curing accelerator application equipment, the core material coated with the main ingredient in the main ingredient application equipment, and the surface layer material in which the curing accelerator is dried in the drying equipment And a transfer facility for transferring and superimposing the core material and the surface layer material which are superposed on each other by the transfer facility,
A transport facility for transporting the core material and the surface layer material to each of the predetermined facilities is included.

In particular, this hardening accelerator coating equipment is provided with a coating roll and a pair of feed rolls. The coating roll is partially immersed in a pan for storing the hardening accelerator, while both feed rolls are fed. The roll is arranged above the coating roll and before and after a vertical plane passing through the rotation axis of the coating roll.

Further, the conveyance equipment located on the carry-in side of the main agent coating equipment and the curing accelerator coating equipment is provided with a conveyance manner enforcing means, and the conveyance manner enforcing means is arranged in the conveying direction on the delivery end side of the conveyor. A stopper plate is arranged transversely, and a driving means for driving the stopper plate up and down is connected to the stopper plate, and a detecting means for detecting whether or not one side of the core material or the surface layer material is in contact with the stopper plate, Control means for activating the drive means in response to the detection output of the detection means.

[0015]

In the above structure, the core material and the surface layer material are transported to the main agent coating facility and the curing accelerator coating facility, respectively, by the transport facility. Then, the core material transferred to the main agent coating facility is coated with the main agent on its adhesive surface, and the surface layer material transferred to the curing accelerator coating facility is coated with the curing accelerator on its bonding surface. Then, the surface layer material coated with the curing accelerator is dried to some extent in the drying facility. Next, after the core material coated with the main agent in the main agent coating facility and the surface layer material in which the curing accelerator has been dried in the drying facility are transferred to each other's bonding positions by the transfer facility and overlapped with each other,
Both are pressed by the press equipment. In this way, since a series of steps are automatically and continuously performed, the number of steps for manufacturing the decorative plywood is saved, the productivity is increased, and the product yield is also improved.

In particular, in the curing accelerator coating equipment, even when the viscosity of the curing accelerator is low, the curing accelerator is abruptly transferred onto the feed roll and the curing accelerator is coated on both surfaces of the surface layer material as in the conventional case. Since there is no inconvenience such as being caused, the curing accelerator can be surely applied only to the required adhesive surface of the surface layer material, and the application operation becomes easy.

Further, the core material and the surface layer material are forced into the main agent coating facility and the curing accelerator coating facility after being forced by the transport mode forcing means so that their transport directions are parallel to the transport direction. Since it is not carried in in an obliquely shifted state, inconveniences such as the core material and the surface material coming into contact with each other in the facility and being damaged are surely avoided.
