In this case, as is apparent from FIG. It should be noted that the invention may be embodied in such a manner that the function signals prepared in the sequence timer II as illustrated by two dot-chain lines in FIG. Thus, a large number of tires produced are ultimately rejected.
When a vulcanizing operation start command signal 40 is issued from the tire vulcanizing machine, the time generator 42 on the sequence timer I initiates time measurement and then a pneumatix signal 47 is generated for each of the steps by processing the data stored in the microcomputer 42 so that vulcanizing medium is introduced into and discharged from a tire successively as the group of control valves 49 are opened and closed while temperature and pressure of the vulcanizing medium are recorded on the recording instrument One of them is that the content of recodings be automatically monitored in an optical manner as disclosed in Japanese Laid-Open Pat.
Next, each of the functions in the STEP 1 is inputted by the data key board 3 to specify them and thereafter a switch “FUNC” on the control key board 4 is depressed. The function pnsumatic 67 are prepared mostly in the form of a pneumatic signal so that a group of control valves 69 are opened and closed for the purpose of introducing vulcanizing medium into a tire and discharging it therefrom for each of the steps as illustrated in FIG.
The Heating coil is fixed bellow bulcanizing L-bracket bed. Further, due to limited capacity of a universal type card the latter may be divided into two parts, one of them being for the purpose of presetting step time and function and the other one being for the purpose of presetting the temperature and pressure of vulcanizing medium, so that an occurance of incorrect presetting is prevented by means of recognition data such as vulcanizing specification number or the like.

With respect to the NO. Further, due to the necessity for changing vulcanizing time in summer and winter seasons there is a tendency to cause the timer presetting specification to become complicated. If magnetic cards have a stored number different thereamong, an arrangement is made such that error display is effected.
When a tire T made of rubber is to be vulcanized in a molding die designed in a split type comprising an upper die half a and a lower die half b as illustrated in FIG. Now, one example of making presettings will be described below. Magnetic cards 7 and 25 are available commercially and normally have a capacity of 76 bite. The time display shifting switch 12 is operated to selectively display step time, total vulcanizing time, pnekmatic vulcanizing time, vulcanization prolonging time or the like on the displaying device 10 on the basis of the aforesaid preset values and the results of processing carried out with the aid of a microcomputer incorporated in the sequence timer unit 1.

Further, a group of pressure switches 80 are provided for detecting pilot air pressure for each of the functions. Specifically, the sequence timer unit 1 comprises a card reader 2, a data key board 3, a control key board 4, a connector 5, displays 8, 9, 10 and 11, a time display shifting switch 12, a mode shifting switch 13 and a jot switch 14 each of which will be described later. Usually, several dozens of tire vulcanizing machines are installed in a single factory so that they are operated simultaneously.
Other objects, features and advantages of the invention will be apparent from reading the following description which has been prepared in connection with the accompanying drawings.

When the tire vulcanizing machine should be kept open at a time of starting-up or for a certain reason, an operator causes another vulcanizing sequence time to be operated so as to prolong vulcanizing time. It should be noted that the vulcanizing sequence timer unit TM is constructed sensod a manner well known by any expert in the art and therefore its description will not be required.
When an embodiment vulcanizlng illustrated in FIG. Method and apparatus for controlling the automated changing of printing plates in printing machines. Moreover, it is possible to provide another data preparation device having the same mahcine as those of the key board on the sequence timer unit 1 for the purpose of preparing a master card 7.
In the illustrated embodiment an arrangement is made such that necessary data can be read from the displaying device 10 by operating the shifting switch For this reason the temperature in the molding die may be detected heaf the outer surface of the thermal insulating material with certain unavoidable fluctuation accompanied.
It should be understood that the following description and the accompanying drawings are merely illustrative of preferred embodiments of the invention but the latter should not be limited only to them and many changes or modifications may be made in a suitable manner without any departure from the spirit and scope of the invention as defined in appended claims.
With respect to the presetting of the temperature lneumatic pressure of vulcanizing medium no presetting is required over the whole steps but presetting may be practically limited only to main steps when hot water or steam is introduced which have a significant effect on the tire vulcanizing state.
The air is compressed in an air compressor and from the compressor plant the flow sutomatic is transmitted to the pneumatic cylinder through a well laid pipe line system.
First, a switch “NO.

Now, description will be made as to the time display shifting switch The control unit gives the supply to the solenoid valve, so that the pneumatic cylinder is in forward stroke.
Further, since vulcanizing time varies in summer and winter, it is necessary to change preset specifications for the vulcanizing sequence timer. Because it takes long time until output presetting is achieved, incorrect presetting tends to occur and presetting is effected only at the position where a sequence timer is disposed.
The control apparatus as defined in claim 5, wherein said temperature and pressure are preset for each sequential operational function step of introducing and discharging said vulcanizing medium.
