Description

Description: TECHNICAL FIELD The present invention relates to a mobile refueling device that is mounted on, for example, a truck carrier and delivers kerosene or the like.

[Conventional technology]

Such a refueling device is provided in parallel with a small oil storage tank that is mounted on a cargo bed, and is equipped with a refueling pump, a flow meter, a refueling hose that can be drawn out, and a refueling nozzle at the tip of the refueling pump. The oil supply amount indicator, which is driven by the sun, is arranged on the outer case so that it can be viewed from the outside. However, this indicator can display only one display content. For example, in order to display the amount of refueling at that time, the total amount of refueling, the failure display, and the like, a large number of indicators must be provided individually.

[Problems to be Solved by the Invention]

By the way, such a mobile refueling device often uses an ordinary gasoline refueling station for fueling automobiles and the like as a refueling base, and an oil storage tank is relatively small, so it is necessary to grasp the loading amount and the remaining amount. In addition, when performing preset refueling, 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,
It would take a lot of space to install a separate indicator to display the loading amount in the tank at the refueling station, the tank remaining amount, the preset amount, or the number of refueling with the same preset amount. I will end up. Also, since many indicators are arranged side by side, it is difficult to see, and there is a risk of misreading the contents of the adjacent indicator.

The object of the present invention is to eliminate the inconvenience of the conventional example, and to display the cumulative amount of refueling, the remaining tank amount, the preset amount, and the number of times of preset refueling with a single indicator, and as a result, save the entire device without taking up space. Another object of the present invention is to provide a mobile refueling device that can be downsized, that the displayed contents are easy to see, and that there is no misunderstanding with the adjacent indicator.

[Means for solving problems]

MEANS TO SOLVE THE PROBLEM This invention memorize | stores the integrated refueling amount area which memorize | stored the integrated refueling amount, the tank residual amount area which memorize | stored the residual oil amount in a tank, the preset amount area which memorize | stored the preset amount, and the frequency of preset refueling. A control device having a RAM in which a preset refueling frequency area is formed,
The power switch, the tank remaining amount switch, the preset switch, the refueling switch is formed into an operating section, and the integrated refueling amount, the tank remaining amount, the preset amount,
A multi-purpose indicator for selectively displaying the preset number of times of refueling is provided adjacent to the refueling amount indicator, and the control device outputs each switch such as a power switch, a tank remaining amount switch, a preset switch, and a refueling switch in the operation unit. Based on the above, the gist is to control the multi-purpose indicator so as to selectively display the cumulative amount of refueling, the remaining tank amount, the preset amount, and the preset number of times of refueling.

[Action]

According to the present invention, since one indicator displays various contents by operation, it does not take up space and is easy to see, and there is little risk of reading errors.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

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

The refueling device 3 is provided with a flow meter provided with a refueling pump driven by a motor 5 and a flow rate pulse generator 6 in a pipe arranged in the outer case 4 and communicating with the oil storage tank 2, and refueling the pipe at the tip thereof. It is connected to an oil supply hose 8 that has a nozzle 7 and can be pulled out from the case 4.

Further, the refueling device 3 is a CPU (central processing unit) 9a, CLOCK9
b, a control device 9 for a microcomputer including a storage device such as a ROM 9c or a RAM 9d, and a power source switch 10a, a tank remaining amount switch 10b, a preset switch 10c, a refueling switch 10d, a hose winding switch 10e, etc. The outputs of the various switches arranged in line are introduced into the control device 9, while the output from the control device 9 is attached to the refueling motor 5, the flow rate pulse transmitter 6, and the outer case 4, and the multipurpose indicator 11A, refueling Introduced into the volume indicator 11B respectively.

Of these, the multi-use indicator 11A is a single indicator that selectively displays the cumulative amount of refueling, the remaining amount of the tank, the preset amount, and the number of preset refueling operations. It is provided adjacent to the quantity indicator 11B.

Then, the RAM 9d of the control device 9 has an integrated refueling amount area 9d-
1, tank remaining area 9d-2, preset amount area 9d-
3, various storage areas such as a refueling number area 9d-4 and a refueling amount area 9d-5 are formed.

The control device 9 includes various switches 10a, 10b, 10c, 10d.
Based on the output from the multi-purpose indicator 11A, the multi-purpose indicator 11A is controlled to selectively display the cumulative amount of refueling, the remaining tank amount, the preset amount, and the preset number of times of refueling.

Further, the refueling motor 5 drives the hose lease by inserting the hose winding switch 10e and reversing it.
The take-up motor of the fuel supply hose 8 is also used.

On the other hand, the multipurpose indicators 11A and 11B both have 7 or 5 date-shaped display segments, which are liquid crystal or diodes, as display elements, and display 7-digit and 5-digit numbers. A total of 11A is used in which each digit can be scrolled and flushed and different contents can be sequentially displayed.

Next, the usage and operation will be described. First, when the power switch 10a is turned on, the numerical value of the integrated refueling amount area 9d-1 is read out, and the past total refueling amount of the refueling device 3 is displayed on the multipurpose indicator 11A. The digits are integrated and displayed (steps (a) and (b) in FIG. 3], and the five-digit number on the display B is zero.

Next, the remaining tank switch 10b or the preset switch 1
Either 0c or refueling switch 10d will be turned on [step (c) (d) (e)].

When the tank remaining amount switch 10b is turned on, it is often performed at a gas station as a refueling base, and the step (a) in FIG. 4 is performed.
When the switch 10b is turned on, the multi-purpose indicator 11A disappears from the accumulated amount display until then, and the remaining amount in the calculated numerical value (for example, if the tank 2 is full and 2000l of oil is stored, 1
After 00l refueling, 1900l is displayed by subtracting 100 from the set value 2000 by the flow rate signal) is read from the tank remaining amount area 9d-2 and displayed. This display is "1 ○ 1900", 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 not, and the operation is continued as it is [Step (c) (d)]. In the latter case, the multi-purpose indicator 11A displays the accumulated amount display. Return to. In the case of the former, it is tank 2 by then
The kerosene is replenished to and the amount of stored oil is measured with a measuring stick. When the switch 10b is turned on, the last four digits of the figure are flushed to enable scrolling. The scrolling is performed in order from the 1st digit, and if the measuring amount is 1870l, the 1000th digit scrolls and flashes from 0 to 2, and when the desired digit in this case "1" appears in that digit. The switch 10b is released to set "1" to the thousands position (step (f) (g)). Similarly, for a digit of 100 or less, press switch 10b again to scroll and flush that digit, and switch when the desired digit is obtained.
Release 10b. In this way, the multipurpose indicator 11A displays "2 ○○ 1870". The number in the first digit indicates the mode.

When the switch 10b cannot be turned on for 5 seconds or more during the process, the digits below it are displayed as "0" and the value is set in the tank remaining amount area 9d-2 [step (wo)]. . Then, the multipurpose indicator 11A returns to the original accumulated amount display [step (e)].

Next, explaining the case of preset refueling,
There are 2 types of presets, 18l and 20l.
As shown in the figure, when the preset switch 10c is turned on [step (a)], the indication "3 ○○○○ 18" is displayed on the multipurpose indicator 11A for 18l first, and this is displayed in the preset amount area 9d-3. It is set [step (b)].
The number in the first digit indicates the mode.

If you want to set a preset amount of 20l instead of 18l, turn on the preset switch 10c again [step (c)], and the multi-purpose indicator 11A will change to "3 ○○○○ 20" and change to 18l instead of 20l. Is the preset amount area 9d-3
On the other hand, if it is desired to proceed with the setting of 18l, the preset refueling is executed if the refueling switch 10d is turned on without turning on the preset switch 10c for the second time [step (e)]. Similarly, if it is desired to execute the preset refueling with the setting of 20 l, the refueling switch 10d may be turned on when the preset switch 10c is turned on 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 [step (f)], the display of the multipurpose indicator 11A returns to the original accumulated amount display [step (h)], and then the refueling switch When step 10d is inserted, it becomes a state where free refueling is possible instead of preset step refueling.When preset switch 10c is inserted in place of refueling switch 10d, the procedure proceeds to step (b) and step (b) above. To do.

Next, the operation after the refueling switch 10d is turned on in step (e) or (g) or (d) of FIG.
Explaining in the figure, the refueling switch 10d is turned on [step (a)], and in the case of free refueling without preset refueling, "step (b)" refueling motor 5 rotates [Fig. 6 step (c)], If the nozzle 7 is opened in this state, kerosene is pumped up from the tank 2 and discharged, and the signal from the flow rate pulse transmitter 6 provided in the flow meter is the oil supply amount area 9d-
5 is added and stored, and the amount of refueling is displayed on the refueling amount indicator 11B. At the same time, this value is added to the stored numerical value in the integrated refueling amount area 9d-1 and subtracted from the stored numerical value in the tank remaining amount area 9d-2.

When the desired amount of oil has been refilled, close the nozzle 7 and refueling switch.
When 10d is turned off, the motor 5 is stopped and the refueling work is completed [step (d)].

On the other hand, in the case of preset lubrication at the step (b) stage, the motor 5 rotates, and for example, in the case of the setting of 18l, the multi-purpose indicator 11A displays "0000018" and the first digit "0" is preset. The number of times of refueling is shown [step (e)].

Preset refueling uses the signal from the flow pulse generator 6
It is performed by comparing with the numerical value stored in the preset amount area 9d-3. When the actual refueling matches the preset value, the motor 9 is stopped by the action of the control device 9 and the refueling is completed. (G)] Then, “1” is added to the numerical value in the refueling frequency area 9d-4. In addition, the value of each area is added and subtracted, and the amount of refueling is the refueling amount display meter.
Displayed on 11B is the same as for free refueling.

In this way, once the motor 5 has stopped for 5 seconds [step (h)], the procedure automatically moves to the step (e), and the motor 5 rotates again to enable refueling. Then, the nozzle 7 is replaced with another empty container and the next preset lubrication is performed. In this case, a multipurpose indicator
The display of the first digit of 11A is changed from the value of the refueling number area 9d-4, that is, from "0" to "1", indicating that one refueling is completed.

On the other hand, if the refueling switch 10c is turned off 5 seconds after the motor 5 is stopped [step (i)], the refueling operation is finished there.

〔The invention's effect〕

As described above, the mobile refueling device of the present invention can display the integrated refueling amount, the tank remaining amount, the preset amount, and the preset refueling number with one indicator, and as a result, the device can be stored in a small space. The entire device can be downsized, the displayed contents are easy to see, and there is no misunderstanding with the adjacent indicator.
