Description

TECHNICAL FIELD

[0001] The present application relates to the field of wind force tobacco feeding technology, in particular to a wind force tobacco feeding tobacco distribution control system. BACKGROUND

[0002] The wind force tobacco feeding technology is the main equipment for conveying tobacco in a cigarette factory. The finished tobacco after being flavored and mixed is conveyed to a cigarette making machine through a tobacco feeding machine and a pipeline. Since the environment requirements of the area for storing tobacco and the area for the cigarette making machine are inconsistent, they are usually in different areas. The wind force tobacco feeding technology adopts a closed tobacco conveying mode, and a production mode is that one tobacco specification is conveyed by one tobacco feeding machine, corresponding to one or more cigarette making machines. The production specifications of the cigarette making machine and the tobacco feeding machine can be changed, and when the corresponding relationship needs to be switched, the tobacco distribution system needs to switch the conveying pipeline in the wind force tobacco feeding system.

[0003] The existing tobacco distribution mode mainly adopts manual pipeline switching, and the control mainly relies on manual disassembly and assembly. The installation precision affects the quality of tobacco. The biggest problem of the manual switching mode is that it is easy to cause pipeline misconnection risk, and there is no automatic monitoring and alarm after misconnection, which easily causes the risk of using wrong materials.

[0030] A wind force tobacco feeding and distribution control system, comprising a centralized control device and a local control device installed on a wind force tobacco feeding machine 3. The wind force tobacco feeding machine 3 comprises two spray valves 6 and two tobacco feeding pipes 2, and a tobacco feeding machine motor 4. The two spray valves 6 are connected to the two tobacco feeding pipes 2 respectively;

[0031] The centralized control device comprises a central control computer, an industrial switch, and a CP communication module. The central control computer is used to display the running state of the equipment, and set the parameters of the motor frequency and the plug valve switching. The central control computer is established with ifix configuration software. The central control computer communicates with the industrial switch through a bus. The industrial switch communicates with the data transmitting module and the data receiving module through the bus. The CP communication module comprises the data transmitting module and the data receiving module. The data receiving module is used to receive the tobacco request signal from the cigarette making machine and the in-place signal of each manual plug valve 5 and automatic plug valve 1. The data transmitting module is used to transmit the tobacco feeding machine start signal and the spray valve 6 start signal. The central control computer is connected to the industrial switch through a PN network cable, and the industrial switch is connected to the CP communication module through a PN network cable.

[0032] The local control device comprises an industrial computer, a controller, a distributed substation box, a manual plug valve 5, an automatic plug valve 1, and a frequency converter. The manual plug valve 5 is installed on one of the two tobacco feeding pipes 2, and the automatic plug valve 1 is installed on the other tobacco feeding pipe 2 connected to the spray port of the wind force tobacco feeding machine 3. The automatic plug valve 1 is controlled by a pneumatic piston to open and close, and two contact type position sensors are arranged on the automatic plug valve 1 to sense the opening and closing of the automatic plug valve 1. The manual plug valve 5 is controlled to open and close by manually pulling the plug, and two contact type position sensors are arranged on the manual plug valve 5 to sense the opening and closing of the manual plug valve 5. The above-mentioned contact type position sensors are connected to the controller respectively.

[0033] The controller is connected to the central control computer, the distributed substation box and the frequency converter respectively. The frequency converter is connected to the motor 4 of the wire feeder. The central control computer is used to display the running or stopping state of each wind force wire feeder 3, and to modify the controller parameters.

[0034] The centralized control device is connected to one or more local control devices.

[0035] A wind force wire feeding tobacco distribution control method, comprising the following steps:

[0036] The manual plug valve 5 and the automatic plug valve 1 are numbered based on the numbering of the cigarette making machine at the end of the wind force wire feeding, and the corresponding pipes of the wind force wire feeder 3 connected to the cigarette making machine are sequentially numbered. Since the cigarette making machine can be connected to 1-3 wire feeders through the pipes, and each cigarette making machine can only receive the tobacco from a unique wire feeder during the wire feeding operation, when the numbered automatic plug valve 1 and the manual plug valve 5 on the same wire feeder are opened, the automatic and manual plug valves 5 on other wire feeders must be closed to successfully start the equipment.

[0037] The opening and closing states of the manual plug valve 5 and the automatic plug valve 1 are determined by the central control computer. The opening and closing states of the manual plug valve 5 and the automatic plug valve 1 corresponding to the same wind force wire feeder 3 must be consistent, and the next step can be executed only after the correctness is determined. For example, 1# and 2# wire feeders are connected to 23# cigarette making machine. At this time, 1# wire feeder needs to be fed, and 2# wire feeder does not need to be fed. When the manual plug valve and the automatic plug valve 1 at the outlet of 1# wire feeder are opened, and the manual plug valve and the automatic plug valve 1 at the outlet of 2# wire feeder are closed, the signal is correct, and the equipment can be normally started. If any of the opening and closing states is incorrect, both wire feeders cannot be started.

[0038] It is detected whether the tobacco request signal from the cigarette making machine is received or not, and the next step is performed after the tobacco request signal is received.

[0039] The in-place information of the manual plug valve 5 and the automatic plug valve 1 is transmitted to the controller at the same time. At this time, the controller transmits a start instruction to the corresponding frequency converter, and sends a tobacco request signal to the upper tobacco storage cabinet, to drive the wind force wire feeder 3 to complete the wind force wire feeding.

[0040] When the cigarette making machine needs to switch to other air force tobacco feeding machine 3, after setting the pipeline path using the centralized control system, the disabled pipeline closes the automatic plug valve 1 and the manual plug valve 5, and the other side pipeline to be enabled opens the automatic plug valve 1 and the manual plug valve 5. After the opening and closing sensor signal on the manual plug valve 5 is unified with the automatic plug valve 1 opening and closing sensor signal, the air force tobacco feeding machine 3 can be started to work, so that each cigarette making machine can only receive the tobacco of the unique air force tobacco feeding machine 3.

[0041] The above has carried on the detailed introduction to the present application, the principle and the implementation mode of the present application are set forth by applying the specific example in this paper, the above example is only for helping understanding the method of the present application and its core idea; simultaneously, for the person skilled in the art, according to the idea of the present application, there will be changes in the specific implementation mode and the application range, and the above-mentioned description should not be understood as the limitation of the present application.
