Description

[Detailed description of the invention] The present invention relates to a thermal control device.

An example of a conventional vulcanizer will be explained based on a tie-P vulcanizer shown in FIGS. 1 to 6.

As shown in Fig. 1, when the tie 'pT is vulcanized in the molds a and b of the upper and lower two-sided structure (but not limited to this), from the inside, the pipe line i, Warm water through 0. By introducing steam or other vulcanizing media, the material is further heated and vulcanized through a 1-mu-made Zurata C.

Reference numeral 1B denotes a mold heating temperature detector, which controls the mold heating temperature with respect to the predetermined temperatures set in 2 above 16 to 18.

Here, due to the change in tie P size, Stellazu and Funksy-1I shown in Fig.
The setting is changed above, and the corresponding mold heating temperature is changed by the operator by changing the temperature setting pointer of the recording controller 16 by MS degrees. For this reason, there is a risk of setting errors and setting misalignment, which is difficult to discern from the appearance of the product type P, and quality deterioration becomes apparent after it is released on the market.
This carries the risk of generating a large number of defective tires.

The present invention was proposed in view of the above-mentioned VC points.

The purpose is to provide a mold heating control device for a vulcanizer that can solve the problems of conventional ones and improve reliability.

The present invention provides a mold temperature control device that controls the vulcanizing medium supplied to the object to be vulcanized in the mold by a control program timer that sets the vulcanization step and function data. In the vulcanizer, the heating temperature of the mold is controlled by setting the heating temperature of the mold by pairing with the data in the 0 column timer, and also controlling the heating temperature of the mold by the output signal from the 0 column timer. It is characterized by having a control system for controlling the mold temperature control device, and the mold heating temperature is set in conjunction with the vulcanization step and fasciculation data on the 5vC-jO gram timer as described above. Since the mold temperature control device is controlled by the output signal of the timer, the mold heating temperature can be set and controlled automatically, thereby eliminating any accidents caused by setting errors, etc. I can do it.

The present invention will be explained below based on illustrated embodiments.

In FIG. 4, numerals 1 to 18 are similar to those shown in FIG. Microphone O Computer 20. Card Gita 21. Facility 3 output mechanism 7. Consisting of mold heating temperature output mechanism 23, tie P specification a
No.

The data on the card 22, which stores the required data such as time, temperature, and mold heating temperature, is sent to the card reader 2.
1, process it with the coater 20,
The output is converted into an external drive signal by the facilitation output mechanism 7 and the mold heating temperature output mechanism 26, and outputted as the funk displacement signal 81 and the mold heating temperature setting signal 24. The signal 8 from the 6-B output mechanism 7 causes the vulcanization step to reach 15V as shown in Figure 2 (each vulcanization step': 15V
In order to introduce the vulcanizing medium into the C type pIE3, the internal pressure ON-OFF control valve group 9 is sequentially opened and closed, and the temperature and pressure of the medium are recorded on the recording controller 13 through the detector 11, and The temperature detected by the metal plate internal temperature detector 18 is feedback-controlled by the adjustment function of the controller 16, and the opening degree of the steam flow control valve 16 is automatically adjusted based on the output signal, thereby controlling the steam flow type to the hot plate. By this, the hot plate temperature C (mold heating temperature) is maintained at a predetermined value.

When the tie P size is changed in the above.

corresponded to its size. 5P specification NO, step time, fu? Insert the card 22, which has been heated to the desired temperature and the mold heating temperature, into the card slot 21 of the timer (2), and store these data in the microcoater 2°.

When the Tachibana vulcanization mechanism sends a vulcanization start command @monthly, the time generator 52 of the timer H starts measuring time, and 5 cycles of phagic A signal is issued, and the vulcanizing medium inside the tire is sequentially introduced and discharged by opening and closing the valve group 9, and its temperature and pressure are recorded on the recorder 13, and the mold heating temperature is also sent to the set value signal 24 from the timer ■. Based on the record/control meter 13. Temperature detector 18. The temperature is maintained at a predetermined value by the flow control valve 16 and recorded.

As mentioned above, the mold heating temperature is set and set in conjunction with the vulcanizing medium step and fascictic settings, and in conjunction with the 51-P specification.
Since it is controlled, there are no setting errors, and it can be easily implemented without making major changes to conventional equipment.

In carrying out the present invention, various applications of the above-mentioned embodiments, such as those described below, can be considered.

All are included within the scope of the present invention.

1) For the timer H card 22, in addition to a magnetic card or Pasiticart, it is also possible to use an EPROM or central data transmission method from the main controller, but in any case, it is possible to use the type P specification, Stellar, fax machine, and mold. The gist of the present invention can be utilized by processing data of heating temperatures as a pair. In addition, if the card capacity is small, divide it into two cards, tie P specification NO, '4 and put this NO. The gist of the invention is satisfied.

2) With conventionally used recording controllers, there are cases in which the temperature setting signal 24 cannot be directly input depending on the model, but this can be handled by incorporating a converter such as an electro-pneumatic converter.

6) Timer Micro], 7Depending on the capacity of the coater 20, it is also possible to incorporate the function of the adjustment side 16.

Further, although the recorder/controller 13 is a shared device, it is also possible to have it separated.

4) In mold heating temperature control, it is also possible to automatically output an alarm when the detected value and the actual measured value are different.

5) It can be applied not only to tires but also to vulcanization of other rubber products.

6) By setting the step time, speed settings, and temperature settings individually on two cards, and setting the recognition data between cards on the cards, you can use general-purpose small capacity cards and avoid card selection mistakes. can also be prevented.
