By pushing either one of switches PB1 to PB5 of a desired sub-tank, a safety circuit and a valve change-over control circuit not shown in the drawing are actuated to change over dampers of branched ducts to the prescribed positions through an electro- magnetic change-over valve not shown in the drawing, corresponding to either one of the switches PB1 to PB5 pushed, and pilot lamps PL8 to PL15 and pilot lamps PL2 to PL6 corresponding to the switches are lighted, whereby the flowing routes come to be indicated by lighting on a control panel Z so that the malfunction can be prevented and the smooth change-over can be achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for remotely centrally controlling a system for transporting and distributing a conveyed material from one location, such as a parent tank, to multiple locations, such as multiple child tanks, by means of fluid pressure, and a system that can be directly used in its implementation. The present invention relates to a directional distribution damper device.

For example, a group of empty plastic bottles for lactic acid drinks discharged from multiple molding machines can be centrally pooled in one parent tank, and placed in child tanks of multiple lactic acid drink filling machines located in separate buildings separated by walls. In the conventional system for distributing and distributing empty bottles from the parent tank through branch ducts by wind pressure, a damper is attached to a Y-shaped branch duct interposed in multiple stages in the middle of the branch duct. The two-way switching operation involved manually switching the damper of each Y-shaped branch duct one by one, so it was necessary to always have personnel available for the switching operation, and it was time-consuming to set up the switching operation. This was a problem that needed to be resolved as soon as possible, as it was difficult to systematically understand the distribution routes, and misunderstandings led to malfunctions and various other troubles.

It is an object of the present invention to provide a remote centralized operation control method and a two-way distribution damper device for a flow distribution system that overcomes and solves the above technical problems.

Press BB to operate the slave tank switching operation control circuit≠3. The child tank switching operation control circuit≠3 is constructed so that the child switches PB, -PB+ do not overlap each other. In response to this, the safety control circuit 1I-6 operates, and the electromagnetic coil 0R21 for the blower/2 interlock operates.
At the same time, the closing contact OR21 is opened to excite and energize the blower power supply operation control circuit≠ to keep it inactive, and the cylinder trouble timer relay coil TM2 with a set time of 20 seconds for the safety control circuit≠6 is activated. Energized and energized. In parallel with this, the valve switching control circuit≠♂ operates, and switches the left and right electromagnetic switching valves VI to V4 of A1-A4 related to the pressed child switches FBI to PBa, and the R solenoid 5Q.
Since L1 to 5OLa are excited, the right solenoid 5OL2

Pressure air is blown into the air cylinder 30 from the lower port 31r, and the piston rod 3.2 is moved out of the air cylinder 30 to lift the crank arm 21A upward, so that it rotates clockwise around the rotating shaft 20. , the switching damper 23 is oscillated to the left imaginary line position shown in FIG. 2 to close the left branch ducts 7c to 10c, thereby communicating the right branch ducts 7b to 10b. Following the operation of the pulp switching control circuit Hiro, the damper left/right switching status display control circuit≠2 operates, and the pilot lamps PLs to PLI5 corresponding to the activated left and right solenoids SQL+ to 5OL8 of the electromagnetic switching valves ■1 to ■4 light up. The damper switching operation completion display control circuit 1AII- operates and the pilot lamps PL2- of the pressed child switches PBs-PB11
Turn on one of PLa.

Therefore, at this stage, according to the lighting display of the small pilot lamps PLa to PL+s on the control panel z and the pilot lamps PLt to PLa of the child switches PBs to PBs, it is possible to switch from the parent tank/ to one child tank 2 to B selected from the parent tank/. It is possible to confirm that there are no errors in the distribution route.

After that, following the operation of the damper switching operation completion display control circuit ≠≠, the switching completion alarm relay coil 0 of the alarm control circuit ≠ 3

Excite and energize the relay open contact f:! Close R1o, turn on the flicker buzzer BZ, and close the slave tank switching operation control circuit 'I.
By opening the automatic reset type timer relay closing contact TM+ of -3 after 10 seconds, the slave tank switching operation control circuit 11-3 is deactivated and the switching completion alarm of the alarm control circuit 4'J- is activated. The relay coil OR+o is demagnetized and an alarm is sounded until the relay opening contact ORto is opened.

In this way, when the child tank switching operation control circuit l/L3 is inoperable, the safety control circuit 4/-6 is also linked and inoperable, and the relay closing contact 0R21 of the blower operation power supply control circuit is closed, and By turning on the switch SN2, the blower operation control circuit is enabled.

Here, B first enters the operating state of the safety control circuit 4,
If 20 seconds or more elapse before the deactivation occurs, the timer relay coil TM2 is activated and the flicker occurs unless the timer relay open contact TM2 of the alarm control circuit ≠j is closed and the alarm stop push button switch PBa is pressed. - Continuing to blink the buzzer BZ causes an inconvenience in the two-way distribution damper device W, and is notified that there is a delay due to trouble with the air cylinder 30, and each two-way distribution damper device W is inspected quickly. Perform maintenance to return to normal operating condition.

Thus, the blower operation control circuit ≠ gA1 switch 8N
When 2 is pressed by a person, the air pressure from the blower 2 is sent into the branch duct // together with the empty bottles, and is supplied to the selected child tanks 2 to B along the distribution route.

During this time, the blower start display circuit≠7 also operates, lights up the pilot lamp FLIT, and opens the relay closing contact 0R22 of the slave tank switching operation control circuit≠3. Switch PB 1”P
Even if B5 is pressed, the slave tank switching operation control circuit 3 is kept inactive.

When the child tanks 2 to B selected from the parent tank are filled with empty bottles, the parent switch 8N2 of the blower operation control circuit tl-ta is turned off and pressed.

By the way, the blowing pressure of blower/2 is a certain standard pressure, for example 3
．． When the pressure drops to 5 to 4.0 or less during the above-mentioned operation and a group of empty bottles cannot be transferred, the open contact PS+ of the pressure switch of the alarm control circuit≠j is closed, and the alarm stop push button is also pressed. By continuing to sound the alarm unless the switch PBe is pressed, it will be notified that a problem has occurred in the flow pressure system including blower/2, and each part of the flow pressure system will be quickly inspected and the system will be restored to normal operating condition. do.

After that, when switching to supply empty bottles from the parent tank L to other child tanks 2 to B, press the child switches FB+ to PBs corresponding to the selected child tanks 2 to B, and follow the same procedure as above. You will need to operate control panel 2.

In the present invention, we have exclusively explained the case of five child tanks, but the number can be increased or decreased as desired, and the branch duct //, sequence control circuit Y, and control panel 2 can be assembled in this way. It is better to use a sequencer instead of a sequence control circuit.
You may also use Furthermore, in the present invention, the feed material is not limited to lactic acid drink bottles, but the object to be treated is applied to other processing lines, and wind pressure is used as the flow medium, but other fluid pressure may be used. Similar effects can be expected.

In this way, the present invention enables remote centralized control of the flow distribution system Therefore, there are fewer erroneous operations, and when a problem occurs, the location of the problem can be accurately identified, so inspection and repair can be carried out quickly.
