Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is used in connection with a sequence controller in order to make each installed device perform a predetermined control operation when constructing a plant for manufacturing liquid foods such as beverage foods and liquid pharmaceuticals. The present invention relates to a wiring device for individual solenoid valve built-in valves.

[0002]

[Prior art]

 Conventionally, the sequence controller 1 and a large number of solenoid valve built-in type valves 2 are connected to the sequence controller 1 by using individual cables 3 for octopus foot wiring as shown in FIG. The number of connected cables 3 must be at least as many as the number of solenoid valve built-in valves 2, and the length of each cable 3 will inevitably become long, and the wiring will be proportional to this. The number of work sites has more than doubled, and labor costs and material costs for construction have increased.

[0003]

[Problems to be solved by the device]

 In consideration of the above situation, the present invention has been devised to simplify the instrumentation work, thereby reducing the number of wiring man-hours and operation check man-hours at the site, and reducing the labor cost and material cost of the work. It is an object of the present invention to provide a new solenoid valve built-in valve wiring device.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a solenoid valve built-in valve wiring device according to the present invention comprises an I / O module mounting base 17, a communication I / O module 18, a terminal block connector 19, and a valve operating solenoid valve 20. A large number of built-in valves 15 are connected to the head portion 16 and the communication master unit 12 is connected to the sequence controller 11 by a dedicated cable 21. The terminals of this communication master unit 12 and the above-mentioned many valves 15 are connected. The terminal block connector 19 in the head portion 16 of each is connected in series by a crossover wiring with a capty cable 14.

[0005]

【Example】

 In the embodiment of the present invention, as shown in FIG. 1, the sequence controller 11 and the communication master unit 12 are connected to each other through the captyre cable and the dedicated cable 21 so that the valves 15 can be connected to each other in series by wiring. In order to implement this system, as shown in FIG. 2, the I / O module mounting base 1 and 7 communication I / O modules (4 inputs, 4 outputs) are installed in the head part 16 of the valve 15 as shown in FIG. (4 points) 18, a terminal block connector 19 and a solenoid valve 20 for valve operation are built in, and each valve 15 is a valve head control system having a controller.

The communication master unit 12 is for switching the signal of the input / output module of the sequence and the packet signal on the communication wiring,

The controller of each valve 15 drives the solenoid valve 20 by a packet on the communication wiring and reflects the limit signal on the packet on the communication wiring.

In the figure, reference numeral 13 is a T-type branch terminal block 13, which is used in an effective place for construction.

The present invention may be embodied by incorporating an address allocation snap switch device for inserting an interrupt into a packet signal on a communication wiring and forcibly executing an on / off operation.

[0010]

[Effect of the invention]

 Since the solenoid valve built-in valve wiring device according to the present invention has the above-described configuration, that is, by incorporating the terminal block connector 19 and the like in the head portion 16, wiring can be performed between the valves. As a result, the labor cost and material cost for construction work can be significantly reduced, and it is extremely effective in achieving the intended purpose.
