The operation method comprises the following steps: power on, water pump on, time setting, filling, water pump off and power off;
starting up:
after the power switch is turned on and the state setting window 25 displays all "8", the state n or o of each filling valve 5 is then displayed. n represents the respective filling valve 5 in the closed state, and o represents the respective filling valve 5 in the open state.
The water pump switch 32 is turned on to feed into the reservoir 1 of the machine.
The filling operation can be performed when the return pipe 19 has liquid flowing out.
Setting the filling time:
the serial numbers of the filling valves 5 from left to right are 1, 2, 3, 4, 5 and 6 in sequence, and the corresponding time settings are 'setting + 1', 'setting + 2', 'setting + 3', 'setting + 4', 'setting + 5' and 'setting + 6' in sequence.
Setting time:
the six heads can be respectively provided with different specifications, and the setting method is similar. The following is given as an example only. Description of the drawings: and the photoelectric device is arranged to fully fill the material in the pipeline. The filling heads are in the corresponding order 1, 2, 3, 4, 5, 6 in the counterclockwise direction from left to right when viewed from the front.
The setting method and procedure will be described by taking the two ends near the control box 17 as an example.
The number "2" on the keyboard is pressed first, and the display on the panel corresponding to the two heads is changed from "O" to "n". Then the measuring cup is placed under the second filling valve. Firstly, pressing a setting key, and displaying a window: and the 'SJ' is put on the number key '2', the eyes look at the prefabricated scales of the measuring cup, for example, 200 ml of the liquid is filled, the eyes look at the scale marks of 200 ml, the fingers press the key 2 but do not leave, the filling head starts to feed, after the materials are filled to the prefabricated scales, the fingers press the key 2 quickly, and then the 'confirm' key is pressed. At this point, the measuring cup or the filling container is carefully compared with the prefabricated scale marks: if the requirements are just met, the setting is finished. If the filling amount is more than the filling amount, the checking key can be pressed, then the key 2 is pressed, then the key micro-reduction is pressed, the time is reduced by 0.01 millisecond once, the continuous pressing is carried out, and the corresponding filling time of the corresponding filling head displayed on the upper edge can be correspondingly changed. Much worse, the micro-minus key can be pressed a few more. And after the time is reduced to a proper value, pressing a confirmation key. After the photoelectric light of the 2 heads is turned on, the filling quantity is compared with the scale marks, and the filling quantity is adjusted accurately in sequence. And treading the foot switch again, weighing the filling quantity, and carrying out fine adjustment if errors exist. The fine tuning is referred to as a "check" operation. Other filling heads may be adjusted in this manner. It is very fast and simple to operate. Otherwise, the filling amount is small, and the same method can be used for adjusting by slightly adding keys.
Setting delay time:
the photoelectric switch 12 is used for controlling blanking, the response is very sensitive, and in order to prevent the filling valve 5 from starting to act under the condition that the filling container is not in place, the working program of the machine increases the function of filling delay. The specific operation is as follows:
pressing the set key to display SJ, pressing 7 to display YS,
a number between 0 and 5 may be entered, with 0 representing no delay, a corresponding 1 representing a delay of 1 second, 2 representing a delay of 2 seconds, and so on.
In general, this delay time may be set to 1 second.
The delay time you can know the current delay time by looking up the key + 7.
And (3) checking operation:
the current working time of each filling valve can be known by a "check" operation. The method comprises the following specific operations: pressing the check key displays that JC appears in the window, and then pressing the corresponding filling valve number displays the current filling time of the valve. Such as displaying: "2 = 3.68", which indicates that the second filling valve filling time is 3.68 seconds.
If you want to fine-tune the time of a certain filling valve 5, you can press the check key and then press the corresponding number key, and after the time of the valve is displayed, you can fine-tune by pressing the micro-plus and the micro-minus. Every time the 'micro plus' key is pressed, the corresponding time is increased by 10 milliseconds; each time the "minify" key is pressed, the corresponding time is reduced by 10 milliseconds. Such as: fill valve number 1 had a time of "1 = 2.24" seconds, and was pressed a "micro" time, indicating a change to "1 = 2.25", and was pressed a second time, indicating "1 = 2.26". And so on. Conversely, if you want to reduce the filling time, you can press "minification", also taking valve No. 1 as an example: if the current time for valve No. 1 is "1 = 2.24", then press a "nudge" for a time of "1 = 2.23", press a second time to "1 = 2.22", and so on. "micro-addition" and "micro-subtraction" can only be used for fine adjustment, and for larger errors, should be directly modified by setting time so as to reach the standard value most quickly.
The work is as follows:
respectively obtaining the corresponding filling time of each filling head according to the method;
setting a delay time;
and (4) placing the container on a workbench, aligning the bottle mouth to the filling head, placing the bottle mouth stably, then separating the bottle mouth by hand, placing the next container, delaying the time, then starting filling the previous container, removing the filled container after filling, and then placing a new container to continue filling.
If one filling head is not operated, the state of the position is changed from 'o' to 'n' only by pressing the corresponding number key, and the filling head is not operated. If the user wants to open the head continuously, the corresponding number key is pressed again.
Shutdown:
the machine has the power-down protection function, data input by the PLC can not be lost after shutdown, and new setting is not needed when the machine works again. When the power-off is carried out, the water pump is firstly turned off, and then the power supply is turned off.
The utility model is simple, practical, high efficiency, high precision and fast; the device has simple structure, is controlled by a key and is convenient to operate; the material storage box is arranged at the top of the frame, so that the pressure difference is increased, and the filling speed is higher; the device is used under the condition of constant pressure and sectional area, the filling quantity can be controlled by using the PLC to control the filling time only according to the proportional relation between the flow of the fluid and the time, and the filling precision is ensured
