ところが、この可使時間と硬化時間とは相関関係があり
硬化時間を短くすれば可使時間も短くなるという関係が
ある。Adhesives were formulated by putting the base agent and hardening agent in a stirring tank, stirring them, and feeding them manually to the applicator or pumping them into the applicator. Once the adhesive is mixed with a curing agent, it begins to harden quickly, so it must be used up within the time it takes to harden. This time is called pot life. On the other hand, once applied as an adhesive, it is better to cure it as quickly as possible so that the next work can be carried out, so the shorter the curing time, the better. However, there is a correlation between the pot life and curing time, such that the shorter the curing time, the shorter the pot life.

ていた。Therefore, even if a large amount of adhesive is blended at once, there is a problem that if the amount used is small, the pot life will be exceeded and the adhesive will begin to harden even though it can be used up completely. On the other hand, there is a problem in that it takes time and effort to mix small amounts in order to use up the product within its pot life. Traditionally, it has taken a lot of effort to formulate adhesives with a short pot life, such as room-temperature curing adhesives used to bond laminated wood, etc., and it has been difficult to press them together at room temperature in a short time. there were. In order to solve these problems, it has been a challenge to develop an adhesive supply method and device that can mix the adhesive in an appropriate amount depending on the amount to be used.

る。The adhesive supply method and apparatus of the present invention will be explained in detail below. FIG. 1 is a piping system diagram of an apparatus used in the adhesive supply method of the present invention, and FIG. 2 is a sectional view showing the structure of a stirring tank of the same apparatus. In the drawing, a base agent tank 1 contains a urea resin, and a curing agent tank 2 contains a 20% ammonium chloride solution. The main agent pump 3 sends the main agent sucked from the main agent tank 1 to the first stirring tank 9 or the second stirring tank 10 via the main agent flow meter 5 and the main agent switching valve 7. The curing agent pump 4 sends the curing agent sucked in from the curing agent tank 2 to the first stirring tank 9 or the second stirring tank IO via the curing agent flow meter 6 and the curing agent switching valve 8. The adhesive in the first stirring tank 9 is taken out by opening the first air cylinder valve 13 and supplied to the applicator 15. The adhesive in the second stirring tank 10 is taken out by opening the second air cylinder valve 14 and supplied to the applicator 15. When the photoelectric sensor 16 detects that the adhesive from the first stirring tank 9 to the applicator 15 has run out, the first air cylinder valve 13 is closed, the second air cylinder valve 14 is opened, and the first air cylinder valve 14 is opened. 9 to the second stirring tank 10 to supply adhesive. Both the first stirrer 11 and the second stirrer 12 have the same structure as shown in FIG. In FIG. 2, a ribbon mixer 19 is provided on the shaft 22 of the stirrer 11, 12, a dispersion blade 20 is fixed to the lower part of the shaft 22, and a shaft of an anchor-shaped blade 21 is fixed to the lower end of the shaft 22, respectively. has been done. The ribbon mixer 19 has a strip of material spirally arranged around the shaft 22, and generates an upward flow in the liquid in the tank in the ribbon mixer 19 portion. The dispersion blades 20 push up the liquid in the tank and change the flow of the liquid in the circumferential direction. The ribbon mixer 19 and the dispersing blades 20 constitute central stirring means. The anchor-shaped feather 21 has an anchor-shaped center portion fixed to the shaft 22, and the anchor-shaped spear portion rotates along the inner surface of the peripheral wall of the stirring tank, thereby scraping off the adhesive adhering to the wall surface. It is something. At the upper part of the stirring tanks 9 and 10, an input port 23 is provided into which the main agent and curing agent are input. The pressure air connection 24 is connected to a dry pressure air source 17, such as a compressor, via a pressure air valve 25,27. This stirring tank9. Since the IO is configured in a confidential manner, when pressurized air is applied, the liquid surface of the adhesive is pushed,
When the air cylinder valves 13 and 14 at the bottom of the tank are opened, the air cylinders are taken out. Examples of the composition of the main resin and curing agent and their pot life are shown below. 20%
Blend 0.25 kg of ammonium chloride solution. At this time, the pot life is 12 minutes, and there is no problem with the pot life in summer. In addition, the main ingredient vinyl acetate latex emulsion 5
1 kg of isocyanate polymer as a hardening agent per kg
may also be blended. At this time, the pot life is 12 minutes,
There is no problem with the pot life in summer. Adhesion can be achieved by applying it to wood and pressing it at a press pressure of 10 kg/cnr for 20 minutes. Further, 0.25 kg of an isocyanate polymer may be blended as a curing agent with 5 kg of a solvent-based rubber resin as a main ingredient. At this time, the pot life is 30 to 50 minutes, but since it is used for about 12 minutes, there is no problem with workability. This greatly improves heat resistance.In this way, according to the adhesive supply device of this invention, even adhesives with a short pot life can be supplied to each of the first stirring tank and the second stirring tank. Mixing and working can be done efficiently by mixing the ingredients in amounts appropriate for the working time and using them alternately. The supply operation by the adhesive supply device having the above configuration will be explained below. 1 and 2, first, the main agent switching valve 7 and the curing agent switching valve 8 are connected to the first
Switching to the stirring tank side, the main agent pump 3 and the hardening agent pump 4 are operated, and the main agent and hardening agent are fed into the first stirring tank 1 and stirred. At this time, the control device 26 monitors the signals from the base resin flowmeter 5 and the hardening agent flowmeter 6, and when the cumulative flow rate of the base resin reaches 5 kg, the base resin pump 3 is stopped, and the cumulative flow rate of the hardening agent reaches 0.25 kg. When the amount reaches kg, the curing agent pump 4 is stopped. Next, the pressure air valve 25 is opened to press the adhesive surface with pressure air, and the first air cylinder valve 13
is opened and the blended adhesive is supplied to the applicator 15. While supplying from the first stirring tank 9 in this way, the solenoid valve 27 of the second stirring tank 10 and the second air cylinder valve 14 are closed, and the main agent switching valve 7
