It states conveyor roller and is divided into several roller-way group sections, each roller-way group section is made of conveying roller described at least one, each roller
Road group section corresponds to a cooling water injection equipment；
The state of the roller-way group Duan Shangyou rolled piece is set as first state by the state for detecting the roller-way group section, will
The state of rolled piece is not set as the second state in roller-way group section；
When the state of roller-way group section is first state, it is cold to control the corresponding cooling water injection equipment closing of the roller-way group section
But water；When the state of roller-way group section is to be switched to the second state by first state, the corresponding cooling water of roller-way group section is controlled
Injection equipment opens cooling water to the roller-way group section spray cooling water.
Preferably, the cooling water injection equipment unlatching cooling water is to the roller-way group section spray cooling water when continuing one section
Between after close, wherein described a period of time be setting time.
Preferably, the setting time is 30 seconds.
Rolled piece conveyor roller cooling control system of the invention and its method are not stopped on conveyor roller using rolled piece
Stagnant rule optimizes.Rolled piece reaches a roller-way group section, then this roller-way group section cooling water is closed, when rolled piece leaves this roller-way
Group section, then this roller-way cooling water is opened.Cooling water be ensure that the cooling effect of conveyor roller, in turn avoid water waste and
Influence to rolled piece temperature.
Detailed description of the invention
Fig. 1 is the structural block diagram of rolled piece conveyor roller cooling control system of the invention；
Fig. 2 is the flow chart of rolled piece conveyor roller cooling control method of the invention.
Specific embodiment
Explain a specific embodiment of the invention in detail with reference to the accompanying drawings.
As shown in Figure 1, rolled piece conveyor roller cooling control system of the invention, including detection unit 10, control unit 20
With roller track cooling device 30, the conveyor roller is made of several conveying rollers, and the conveyor roller is divided into several roller-way groups
Section, each roller-way group section are made of conveying roller described at least one；The roller track cooling device 30 has multiple cooling water injections
Mechanism, each corresponding roller-way group section of the cooling water injection equipment, is used for the roller-way group section spray cooling water.
The detection unit 10 is used to detect the state of the roller-way group section, by the state of the roller-way group Duan Shangyou rolled piece
It is set as first state, by the state of rolled piece is not set as the second state in roller-way group section.The detection unit 10 can adopt
With for video camera, image tracking is carried out to rolled piece by video camera, it is existing for using video camera to carry out the specific method of image tracking
There is technology, which is not described herein again.The detection unit 10 can also use thermometal detector, can also be using other sensings
Device.The testing result of detection unit detection includes the first state of roller-way group Duan Shangyou rolled piece, does not roll in roller-way group section
The state that the second state and rolled piece of part are left from roller-way group section, that is, be switched in roller-way group section by first state
Second state.
Described control unit 20 controls the cooling water injection equipment according to the testing result of the detection unit, works as roller-way
When the state of group section is first state, controls the corresponding cooling water injection equipment of the roller-way group section and close cooling water；When roller-way group
When the state of section is the second state, first judge whether it is that the second state is switched to by first state, if so, controlling the roller-way group
The corresponding cooling water injection equipment of section opens cooling water to the roller-way group section spray cooling water, if it is not, closing cooling water.
