Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mobile refueling device that is mounted on, for example, a truck or truck carrier and delivers kerosene or the like.

[Conventional technology]

Such a refueling device is equipped with a refueling pump, a flow meter, a retractable refueling hose, and a refueling nozzle at the tip of the refueling hose, which is installed in parallel with a small oil storage tank that can be placed on a loading platform. A refueling amount display needle with a series of mouth-shaped display segments that are driven by the engine is attached to the exterior case, allowing the remaining amount to be read from the outside. However, this display meter can display only one display content, and for example, a large number of individual display meters must be provided to display the current amount of oil supplied, the total amount of oil supplied, a malfunction, etc.

[Problem that the invention seeks to solve]

By the way, these mobile refueling devices often use regular gasoline refueling stations for refueling cars, etc., and the fuel storage tanks are relatively small, so it is necessary to keep track of the amount loaded and the remaining amount. In addition, when performing preset lubrication, it is necessary to display the amount in advance for confirmation.

In addition to the total amount of refueling up to now and the amount of refueling at that time,
Providing individual display hands to display the amount loaded into the tank at the supply base, the remaining amount in the tank, the preset amount, or the number of refuelings with the same preset amount would take up space and make the entire device thick ( Also, since many display meters are arranged in parallel, it is difficult to see, and there is a risk of misreading the contents of the neighboring display hands.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the disadvantages of the conventional example and to provide a mobile refueling device that is small in size and has an easy-to-read display.

c. Means for Solving Problems] In order to achieve the above object, the gist of the present invention is to provide a multipurpose display meter that displays various information with one display hand.

[Effect]

According to the device of the present invention, one display hand displays various contents by operation, so it does not take up much space, is easy to read, and has little risk of misreading.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a perspective view showing an embodiment of the oil supply device of the present invention;
The figure is a block diagram of the same as above, and in the figure, 1 is a small truck, on whose loading platform 1a an oil storage tank 2 and an oil supply device 3 of the present invention are mounted.

The refueling device 3 has a flow meter equipped with a refueling pump driven by a motor 5 and a flow rate pulse transmitter 6 attached to a pipe disposed inside an exterior case 4 and communicating with the oil storage tank 2, and a flow meter equipped with a flow rate pulse transmitter 6 is installed at the tip of the pipe. It has a nozzle 7 and is connected to a refueling hose 8 that can be drawn out from the case 4.

Furthermore, the oil supply amount W3 is determined by the CPU (central processing unit) 9a,
, CLOCK 9b, ROM 9c, RAM 9d storage devices, etc. are built-in micro-combination controllers 9, including a power switch tOa, a tank remaining amount switch 10b, a preset switch 10c, a refueling switch 10d, and a hose winding switch. The outputs of various switches arranged on the operating section such as 10e are introduced into this control device 9, while the outputs from the control device 9 are sent to the refueling motor 5, the flow rate pulse transmitter 6, and the display meter 11 attached to the exterior case 4.
A and display meter 11B are respectively introduced.

The RAM 9d of the control device 9 has an integrated oil supply area 9d-1.
, tank remaining amount area 9d-2, preset amount area 9d
-3, Refueling frequency area 9d-4 and refueling amount area 9d-
5 various storage areas are formed. Further, the refueling motor 5 drives the hose reel by turning on the hose winding switch toe and reversing the switch, so that the refueling motor 5 also serves as a winding motor for the refueling hose 8.

On the other hand, the display meters 11A and IIB both have 7 or 5 mouth-shaped display segments arranged in parallel using liquid crystals or diodes as display elements, and display 7-digit and 5-digit numbers. Use a device in which each digit can be scrolled and flashed, and different contents can be displayed sequentially.

Next, to explain the usage and operation, first, when the power switch 10a is turned on, the numerical value in the cumulative oil supply area 9d-1 is read out, and the past total oil supply amount of this oil supply device 3 is displayed on the display meter 11A. The total is displayed in digit numbers [Fig. 3 Ste knob (a) and (b)], and the 5-digit number on display meter B has returned to zero.

Next, either the tank remaining amount switch tab, the preset switch 10c, or the refueling switch 10d is turned on [steps (c), (d), and (e)].

When turning on the remaining tank level switch tab, this is often done at a refueling station that serves as a replenishment base, and the step shown in Figure 4 (
When the switch 10b is turned on as shown in b), the display meter 11
The display of the accumulated amount up to that point disappears on A, and the remaining amount on the calculated value!
(For example, if tank 2 is full and 20001 oil is stored, after refueling 100N, 19006 is set to 200.
100 is subtracted from 0 by the flow rate signal and displayed),
It is read out from the tank remaining amount area 9d-2 and displayed.

This display is r 1001900J and the first "1"
indicates the mode, and the last four digits indicate the amount [step (b)].

The operation is divided depending on whether the tank remaining amount switch 10b is turned on again within 5 seconds or whether the remaining amount remains as it is (steps (c) and (d)); in the latter case, the display on the display meter 11A returns to displaying the accumulated amount. . In the former case, tank 2 has been filled with kerosene and the amount of oil stored is measured with a measuring rod, and when the switch tab is turned on, the last four digits of V will flash and scrolling will be possible. Become. The scrolling is performed in order from the ones digit, and if the scale amount is 1870/, the thousands digit scrolls and flashes from O to 2, and the desired digit, in this case "1", appears in that digit. Sometimes, by releasing the switch tab, "1" is displayed in the thousands place.
” [step (to) (g))].

Similarly, for digits less than 100, switch 1ob is pressed again to scroll and flash the digit, and when the desired number is obtained, switch 10b is released. In this way,
The display meter 11 displays r 2001870J. The first digit indicates the mode.

If the switch TAB is not pressed for 5 seconds or more while scrolling through each digit, the lower digits are displayed as rOJ and the value is set in the tank remaining amount area 9d-2 [Step (w)]. Then, the display meter 11A returns to the original integrated amount display [step (e)].

Next, I will explain the case of preset lubrication.
Two types of preset settings are possible: 181 and 2ON, and as shown in Fig. 5, when the preset switch 10c is turned on [step (a)], "3000018" is displayed on the display 11A regarding 181. is displayed, and this is set in the preset amount area 9d-3 [step (b)]. The first digit indicates the mode.

207 instead of 181! If you want to change the preset amount, turn on the preset switch 10c again [step (c)], and the display meter 11A changes to "r 3000020" and instead of the 181 setting, it reads 207! is set in the preset amount area 9d-3 [step (d)].

On the other hand, if you want to proceed with the setting 181, turn on the refueling switch 10d without turning on the preset switch 10c for the second time, and preset refueling will be executed [Step (e)]
. Similarly, if you want to execute preset oiling with the setting of 20f, you can turn on the oiling switch 10d after turning on the preset switch 10c for the second time [step (g)].

If the preset switch 10c is turned on for the third time without turning on the refueling switch 10d, the display on the display meter 11A returns to the original integrated amount display [Step (H)].
], then turn on the refueling switch lOd and turn on [step (
)] Free lubrication is possible instead of preset lubrication. On the other hand, when the preset switch 10c is turned on instead of the refueling switch 10d [step (N)], the procedure shifts to the aforementioned step (B).

Next, the operation after the refueling switch 10d is turned on in step (E), (G), or (S) of FIG. 5 will be explained with reference to FIG. 6. ], in the case of free refueling without preset refueling, the refueling motor 5 rotates [step (c) in Figure 6], and in this state, when the nozzle 7 is opened, kerosene is pumped up from the tank 2. The signal from the flow rate pulse transmitter 6 provided on the flow meter is added and stored in the oil supply area 9d-5, and the oil supply amount is displayed on the display meter 11B. At the same time, this value is the cumulative oil supply area 9d-
It is added to the stored numerical value of 1 and subtracted from the stored numerical value of tank remaining amount area 9d-2.

Once the desired amount of oil has been refilled, the nozzle 7 is closed and the refueling switch 10d is turned off, thereby stopping the motor 5 and completing the refueling operation [step (d)].

On the other hand, in the case of preset lubrication in step (B), the motor 5 rotates, and for example, if the setting is 181, the display meter 11A will display roooo018 J, and the first digit "0" indicates the number of preset lubrications. It shows [step (e)].

For preset lubrication, the signal from the flow rate pulse transmitter 6 is
This is done by comparing the value stored in the preset amount area 9d-3, and when the actual lubrication and the preset value match, the motor 5 is stopped by the action of the control device 9 and the lubrication is completed [step (to) (to)). Then, "1" is added to the numerical value in the refueling frequency area 9d-4. Note that the numerical values in each area are added and subtracted, and the amount of refueling is displayed on the display hand 11B, as in the case of free refueling.

In this way, once the motor 5 has stopped and 5 seconds have elapsed, [
The process will automatically proceed to step (H)] and step (E), and the motor 5 will rotate again and become ready for refueling, so please return the nozzle 7 to another empty container before the next Perform preset lubrication. In this case, the display meter 11A
The display of the first digit changes from the value in the refueling frequency area 9d-4, that is, rOJ., to "1", indicating that one refueling has been completed.

On the other hand, if the refueling switch 10c is turned off before 5 seconds have elapsed after the motor 5 has stopped [step (S)], the amount of refueling ends there.

〔Effect of the invention〕

As described above, since the mobile refueling device of the present invention uses a multi-purpose display meter as the display meter, various indications can be made with a 1 irM display meter, and as a result, the entire device can be displayed without taking up much space. can be made smaller.

The displayed contents are easy to see, and there is no possibility of misreading the display with the display next to it.
