DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a code dipping machine , and more particularly, to a code dipping machine for impregnating a cord used for a core wire of an industrial belt for power transmission or the like with a treatment liquid serving as an adhesive liquid. About.

[0002]

2. Description of the Related Art Industrial belts for power transmission, such as V-belts, V-ribbed belts, and toothed belts, are made of a fiber material such as polyester fiber, aramid fiber, or glass fiber as a core wire as a tensile member. And the code is used. This cord is RFL-treated only, or RFL-treated after pre-treatment with epoxy or isocyanate compound, or RF-
After the L treatment, rubber paste was adhered.

[0003] The cord is continuously pulled out of the creel while applying a constant tension by a first driving roll in a cord dip processor, impregnated with an adhesive in a first dip tank, and then placed in a first oven. After being sent and dried by heating, it is cooled outside the oven to complete the first processing step, and then repeatedly passes through the same processing steps as the second, third and fourth steps, and a different blending is performed for each step. The belt was heated and stretched under different oven temperature conditions and tension conditions to impart optimum cord physical properties to a belt, wound around a reel, and completed the dipping process.

[0004] In a cord dip processing machine, the winding of an untreated white cheese cord and the beginning of the winding of another white cord cheese are usually joined together at a creel stand, while the winding reel of the treated cord has a spare. When the reel is ready to take up the cord, the reel is switched to the spare reel, and the continuous processing operation is performed regardless of the length of one turn of the white cord.

In this case, it was necessary to frequently replenish the processing liquid in each dip tank in order to keep it at a constant level.
Therefore, possesses service tank for each dip tank, to automatically supply the process liquid from the service tank, a least number of level switch also detects the height of the liquid level in the dip tank, the signal An automatic supply device equipped with a pipe having an automatic switching valve that opens and closes upon receiving the gas was equipped.

[0006]

In such a dip tank, the upper and lower limits of the processing liquid level are detected, and the ON-
In the liquid supply system that controls OFF, there is a difference in the liquid height between the start and end of the supply of the dip liquid. This resulted in a difference in the immersion time, and a precise basis weight of the treatment liquid with respect to the cord could not be ensured, resulting in variation in the properties of the cord.
If an excessive level of the basis weight processing is performed in order to avoid the shortage of the basis weight, the cost has increased.

[0007] Further, since the treatment liquid uses a solution based on rubber or resin, these contents may be solidified during a long-time operation. There has been a problem that the automatic opening / closing valve is clogged due to the adhesion of the solidified matter, and the trouble of malfunction is easily caused. In addition, since processing solutions containing organic solvents such as toluene, which are generally used as solvents, are used, in these processes, in order to prevent fire and disaster, a level switch, an automatic switching valve, etc., should come into contact with the processing solution. Needed to use explosion-proof equipment. However, it has many drawbacks such as an increase in size due to heavy equipment, difficulty in maintenance work, and an increase in equipment costs.

Further, in recent years, reflecting the trend toward small-lot production of various types, the number of processing liquid switching setups and the number of types of processing liquids have increased due to the reduction in the number of code processing lots and the number of processing liquids.
The number of service tanks and their associated feeders has increased, and improvements have been strongly sought.

In view of the above situation, the present invention has been made to solve such problems, and a processing liquid in a processing liquid tank is always supplied to a dip tank in a substantially constant amount, and the processing liquid is attached to and detached from the dip tank. It is an object of the present invention to provide a code dip processing machine which can always perform accurate and stable dip processing irrespective of the length of the code dip processing time by using a possible processing liquid tank and which is easy to handle.

[0010]

That is, according to the present invention, a cord used for a core wire of an industrial belt for power transmission or the like is treated with a treatment liquid.

Dodip processing machine.

Further, the present invention makes it possible to disassemble the processing liquid tank with a lower flange having an inner diameter equal to the inner diameter of the body at the lower end of the body and a lower flange in which a conduit is fitted. It includes a processing liquid supply device in a mounted code dip processing machine, and a code dip processing machine in which at least two or more processing liquid tanks and conduits connected to each processing liquid tank are arranged for one dip tank.

Further, the present invention also includes a code dip processor provided with means for displaying the weight of the processing liquid tank on a bracket for mounting the processing liquid tank on the dip tank.

[0013]

According to the first aspect of the present invention, since the conduit having the on-off valve is connected between the processing liquid tank which is detachable and contains the processing liquid and the dip tank, the on-off valve is connected. When the opening is opened, the processing liquid in the processing liquid tank is discharged by its own weight to the dip tank located below, and the liquid level rises.
To reach the opening of the conduit and shut off the atmosphere. Inside the dip tank
When the processing liquid is consumed and the liquid level drops, air
Instantaneously penetrates into the tank, and at the same time the processing liquid is discharged,
At this time, the internal pressure increases due to the increase in the volume of the space in the processing tank.
While the discharge of the processing liquid is stopped. Thereafter, as the processing liquid in the dip tank is consumed, the above operation is repeated, so that the level of the processing liquid in the dip tank can always be kept substantially constant, so that accurate and stable dip processing can be performed. Also, the only movable part of the processing liquid supply device of the code dip processing machine is the open / close valve, and the frequency of opening / closing is limited when the processing liquid tank is filled with the processing liquid and when it is attached to and detached from the dip tank. It is possible to prevent an unexpected trouble during the operation due to the sticking of the residue and the bitten of the residue, and it is possible to stably supply the processing liquid.

According to the second aspect of the present invention, a flange having an inner diameter equal to the inner diameter of the main body and a flange fitted with a conduit are detachably attached to the lower end of the main body of the processing liquid tank. Therefore, the lid of the processing liquid tank can be opened by separating and disassembling the flange portion. As a result, it is possible to easily check and clean the residue and solid matter of the liquid to every corner in the processing liquid tank. Since the flange is located at the lower end of the main body, after filling the processing liquid, the pipe should be oriented downward and installed in the dip tank, making it very easy to leak liquid from the joint of the flange before use. Presence, that is, the sealing function of the tank can be checked.

According to the third aspect of the present invention, by replacing the processing liquid tank, it is possible to cope with long-term continuous operation and to supply a processing liquid having a stable quality at all times. In addition, when the same type of code is subjected to the dip processing, the consumption amount of the processing liquid per time is almost constant, the liquid filling amount in the processing liquid tank is measured, and the liquid amount in one processing liquid tank is reduced. Oh
With extra time, use a spare processing solution tank together,
By temporarily supplying the two processing liquid tanks until one of the processing liquid tanks becomes empty, the processing operation can be performed without being strictly restricted by the switching time. For this reason, the operator can handle a plurality of dip processing machines or perform other tasks, and thus very high convenience can be obtained.

According to the fourth aspect of the present invention, by previously measuring the empty weight of the processing liquid tank, the amount of liquid in the tank can be constantly grasped, and the amount charged at the end of the dip processing operation is minimized. And the remaining amount of the processing solution can be reduced.
