BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dip device for a cord processing machine, and more particularly to a dip device for applying a cord used for a core wire of an industrial belt for power transmission or the like with a treatment liquid such as an adhesive. A leader code for guidance is connected before and after the power code, and the dip tank is automatically raised or lowered immediately before or immediately after the connecting portion of the leader code passes through the dip tank, and the processing liquid is supplied to the main part of the leader code. The present invention relates to a dip device in a code processing machine that does not adhere.

[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 (resorcin formalin latex) treated only, or RFL treated after pre-treatment with epoxy or isocyanate compound, or rubber glue is adhered after RFL treatment in order to enhance the adhesiveness with rubber material. I was

[0003] The above code is used in a code processing machine.
It is continuously pulled out from the creel while applying a certain tension by the driving roll, impregnated with the adhesive liquid in the first dip tank, sent to the first oven, heated and dried, cooled outside the oven, and cooled. After the completion of the first processing step, the same processing steps as the second, third, and fourth steps are repeated, and each processing step is impregnated with a processing solution having a different composition, and then, a different oven temperature is applied. Under the conditions and tension conditions, the belt was heated and stretched, the belt was given optimum cord physical properties and wound up on a reel, and the dip treatment was completed.

[0004] In the cord processing machine, usually the end of winding of a white cheese cord untreated in a creel stand;
The other end of the cheese cord on the white background is tied at the beginning and the spare reel is prepared as a reel for the processed cord. When the detection sensor detects the passage of the cord joint, it automatically switches to the spare reel. Therefore, continuous processing operation was performed regardless of the length of one turn of the white background cord. (For example, disclosed in JP-A-4-146229)

When the dipping process is completed,
An aramid fiber cord, which is a heating cord that does not change with heat, was joined to the end of the cord to be finally treated. When the dip processing is completed, the detection sensor detects the passage of the joint, and when the joint reaches the winder, heating of the oven heater, cord feeding, and the like are stopped. Further, even when the temperature of the oven for heating and drying is increased, the heating cord located in the oven does not change due to heat, thereby eliminating the cord loss. (See, for example, JP-A-4-1462)
No. 32)

[0006]

However, in the conventional code processor, the guide code is immersed in the processing liquid stored in the dip tank while the leader code for guiding is stopped, and the processing liquid adheres. The cord was running around the oven. Since the leader code extends from the creel stand to the length of the winder, and the processing liquid is adhered almost over the entire length of the heating cord, the usage amount of the processing liquid has increased.

Therefore, conventionally, when the leader code passes, all the dip tanks have been manually lowered by the operator. Then, manually raise the tip of the cord to be processed immediately before entering the dip tank, or manually supply the processing liquid to each preset dip tank,
At the end of the dipping process, each dipping tank was manually lowered in the reverse order. Therefore, the operation of moving a large number of dipping tanks up and down in view of the timing is complicated and not only requires human labor, but also at the start of the dipping process, the level (amount) of the processing solution tends to vary, making it difficult to perform an accurate dipping process. There were problems such as becoming.

The present invention has been made in view of the above situation, and has been made to solve such a problem. The present invention automatically moves up and down a dip tank without requiring any manual operation and only when passing a cord to be processed. It is an object of the present invention to provide a dipping device in a code processor capable of adhering a processing liquid and maintaining a level of the processing liquid constant over almost the entire length of a code to be processed, and capable of always performing accurate and stable dipping.

The control means 110 activates the first, second, third, fourth, etc. dip tank lifting / lowering means after a while, starts and stops the operation of the code processor 1, and starts and stops the heating of the oven. , A signal for starting and stopping the hot air circulating fan 9, the processing speed of the code (reference speed),
A function is provided for performing arithmetic processing using the stretching ratio, the oven temperature, that is, the dimensional change of the oven due to thermal expansion, and the path distance, which is the distance from the detection means to each dip tank, as parameters.

Specifically, as shown in FIG. 7, the control means 110 comprises a sensor control circuit 111, a roll drive control circuit 112, and a dip tank elevating control circuit 113. The sensor control circuit 111 sends a signal for determining the start and end of processing from the detection means 25 for detecting the passage of the connecting portion 18. The signal drives the roll drive control circuit 112 and the dip tank elevating control circuit 113.
In the roll drive control circuit 112, the rotation speed of the roll is calculated by a computer using the data A based on the reference speed of the code, and the rotation of the drive roll 17a is adjusted by the speed control device 115 to extend the data A and the preset code. The rotation of the drive roll 17b is controlled by the data B calculated based on the rate, and the drive roll 17c is controlled by the data C calculated based on the data B and the elongation rate of the code.

The movements of 17d and the dip tank 34 are completely reversed from those at the start. Detecting means 25 includes code 10 and reader code 10
When the passage of the connecting portion 18 with R is detected, the dip tank raising / lowering control circuit 113 operates to immediately lower each dip tank 34 to the lower limit position immediately after the connecting portion 18 passes each dip tank 34. At the same time, a signal is sent to the control circuit of the oven, and when the connecting portion 18 arrives immediately before the winder 70, the winder 70 and the driving rolls 17a to 17a.
17e is stopped, the cord feed is stopped, and the heating of the oven in all the processing units is stopped. When the oven reaches the fan stop temperature arbitrarily set, the hot air circulating fan 9 is also stopped to operate the cord processing machine 1. Stop. Since parameters such as the path distance differ depending on the type of the code to be processed, the parameters are managed as a parameter group for each code type together with parameters such as the reference speed, the elongation ratio, the oven temperature, that is, the dimensional change of the oven due to thermal expansion.

The connecting portion 18 is separated, and the cord 10 is switched to another take-up reel 72. Thereafter, the code 10 can be processed continuously. When the connecting portion between the cords 10 passes through the detecting means 25, the control means 110 is stopped in advance.

(6) When the dip processing of the code 10 is completed, the reader code 10R is connected after the code 10. Detecting means 25 has code 10 and reader code 10R
The first dip tank lifting / lowering means 80 is activated immediately after the connection portion 18 has passed the first dip tank 34 by this detection signal, and the dip tank 34 is moved to the upper limit position. To the lower limit position. That is, the rod 94 of the cylinder 90 is extended to move the slider 91 downward, and the dip tank support 81
The dipping tank 34 is lowered to the lower limit position and stopped against the elastic force of the leg portion 84 while pressing the tray 85 of FIG.

(7) The second, third, fourth, etc. dip tank lifting / lowering means 80 are activated after a certain time by the control signal transmitted from the control means 110. Then, the control means 110
When the connecting portion 18 reaches just before the winder 70, the winder 70 and the driving rolls 17a to 17e are stopped, and the heating of the oven is stopped. Further, when the temperature of the oven drops to an arbitrary set fan stop temperature,
The hot air circulation fan 9 of the oven is stopped. In this way, the processing operation of the code processor 1 is automatically stopped before the connecting portion 18 is wound on the winding reel 72 of the winder 70.
In preparation for the next operation, the worker separates the connecting portion 18 between the code 10 and the leader code 10R, sends out the leading end of the leader code 10R to the winder 70 by the operation of feeding the code, and winds it around another reel 72 several times. Keep it. At this time, the leader code 10R is passed over the entire processing zone from the creel stand 15 of the code processor to the winder 70.
