Description

The present invention relates to a liquid delivery system for delivering a liquid to a user.

Conventionally, when delivering a liquid such as lubricating oil or fuel to a user, a drum can filled with the liquid is delivered to the user by a truck or the like, and the user collects the empty drum can after the liquid is consumed. A liquid delivery system using the above is widely used (see, for example, Patent Document 1). Drums with a capacity of 200 liters are generally used.

Japanese Unexamined Patent Publication No. 10-265055

However, when the liquid is filled in a drum can having a capacity of 200 liters, the weight exceeds 200 kg. The delivery and transportation of such heavy objects imposes a heavy physical burden on the operator, and care must be taken in handling the drums in order to ensure the safety of the work.
In addition, the user pumps the liquid from the drum can and uses it, but since it is difficult to detect the remaining amount of liquid in the drum can, the amount of liquid used at that time does not remain in the drum can, or the pump is used. Since it is found that the drum can is empty after the liquid cannot be pumped out, it is inconvenient that the work to be carried out using the liquid is stopped in some cases because it is waited until the new liquid is delivered. there were.

Further, in order to reuse an empty drum can collected from a user, depending on the type of liquid, cleaning including a plurality of cleaning steps using a plurality of different detergents is performed in order to remove stains on the inner wall surface. I needed it.
Such a cleaning process increases the cost required for reusing the drum can, generates a relatively large amount of waste liquid and imposes a burden on the environment, and since the drum can can be reused only several times, the drum can can be reused. Was not actively reused, and it was common to shred it with a burner or the like and use it as an iron resource.
Further, in the liquid delivery system using the drum can, the retail price of the liquid must include the cost required for the drum can, which imposes a heavy burden on the user.

An object of the present invention is to reduce or eliminate the waiting time of the user while reducing the physical burden on the operator, improving the safety of the work, and reducing the environmental burden when delivering the liquid to the user. To provide a liquid delivery system that can.

As a result of diligent studies to solve the above problems, the present inventors have made a liquid delivery system capable of delivering a liquid to a user in a timely manner according to a liquid consumption situation in the user without using a drum can. The present invention has been completed.

According to the liquid delivery system of (1) above, the storage tank, the remaining amount information detection unit that detects the remaining amount information of the liquid in the storage tank, and the reception of the remaining amount information provided in the delivery source, the delivery vehicle, or the like. By installing a transmission unit that transmits to the unit for each user who is the delivery destination, a delivery vehicle can be dispatched according to the remaining amount of liquid in the storage tank, and the liquid can be replenished to the storage tank. The user's waiting time for delivery can be reduced or eliminated.
Further, by replenishing (injecting) the liquid in the delivery vehicle, it is possible to retail, for example, in units of 1 liter according to the user's request, so that the burden on the user can be reduced.

In addition, by installing storage tanks at each delivery destination and using a delivery vehicle equipped with a delivery tank that is not a drum can, the use of drum cans becomes unnecessary, so workers who deliver liquids to users Significantly reduces the physical burden on the user who handles the liquid, significantly improves the safety of work and handling, shortens the work time, increases the cost associated with the reuse of drums, wastes resources, and so on. The burden on the natural environment can be eliminated.
In addition, since it is possible to replenish the liquid before the liquid in the storage tank runs out, the capacity of the storage tank can be made smaller than that of the drum can, for example, depending on the consumption status of the liquid by the user. It is not necessary to provide a relatively large space such as a drum storage space, and the space can be effectively used.
Further, since the retail price of the liquid may be lower than before due to the non-use of the drum can, the burden on the user can be reduced in this respect as well.

As the transmission unit 11, for example, a communication terminal device that uses a telecommunication circuit may be used.
As the communication terminal device, for example, a computer, a workstation, a smartphone terminal, a tablet terminal, a mobile phone terminal, or the like can be used.

The transmission unit 11 of another form is composed of, for example, an electronic circuit for detecting the remaining amount information including a CPU (central processing unit), a memory, a timer, and the like, and a communication terminal device.
In the present embodiment, the CPU controls the detection of the remaining amount information at predetermined time intervals by the remaining amount information detection unit, writes the obtained remaining amount information to the memory once, and then receives the remaining amount information via the communication terminal device. Send to.
When a communication terminal such as a computer, a workstation, a smartphone terminal, or a tablet terminal is used, the electronic circuit built therein can be used as the electronic circuit for detecting the remaining amount information.
Further, the CPU of the transmission unit 11 compares the remaining amount with the reference amount, and when the remaining amount is equal to or less than the reference amount, the delivery source 3 uses information indicating that the remaining amount is equal to or less than the reference amount as the remaining amount information. It can also be set to send to.

Further, the tank body 20 is provided with a remaining amount warning means (not shown), and when the remaining amount reaches a predetermined amount (amount larger than the reference amount for determination), the liquid is supplied to the worker at the delivery destination 2. You can also set it to let you know that the time is approaching.
For example, a lamp, an analog meter, a digital meter, a buzzer, or the like can be used as the remaining amount warning means.

More specifically, in the memory of the electronic circuit for detecting the remaining amount information or the electronic circuit built in the communication means, the date and time of the previous liquid replenishment, the date and time elapsed from the previous date and time of the liquid replenishment, and the date and time per day at the delivery destination 2. Enter information such as standard liquid consumption in advance.
Then, the CPU in the electronic circuit calculates the date and time until the next liquid replenishment is required based on the above information and the remaining amount information, and the date and time until the next liquid replenishment is, for example, 2 based on the calculation result. It is determined whether it is within 2 days or more than 2 days, and based on the determination result that it is within 2 days, the CPU sends a control signal to the remaining amount warning means, the lamp, the meter, etc. blink in different colors, and also. The buzzer or the like can be controlled so that a warning sound is emitted, and the worker at the delivery destination 2 or the like can be notified that the liquid supply time is approaching.

Further, it is possible to set the delivery source 3 to send the information indicating that the refueling time is approaching as a part of the remaining amount information.

Next, the computer 12 installed in the delivery source 3 will be described. A communication interface circuit (not shown) corresponding to the above-mentioned telecommunications means is connected to the computer 12.
In the present embodiment, the computer 12, more specifically, the electric circuit including the CPU, memory, timer, etc. built in the computer 12 also serves as a determination unit and a delivery instruction unit, and the communication interface circuit serves as a reception unit. ..

The remaining amount information and the current position information of the delivery vehicle 4 are input to the memory through a telecommunication circuit. Further, in the memory, for example, a reference amount (numerical value) for determining the remaining amount information, the capacity of the storage tank 10 (tank body 20) installed in each delivery destination 2, and the liquid used in each delivery destination 2. Type, standard consumption of liquid at each delivery destination 2, last replenishment date and time and replenishment amount of liquid at each delivery destination 2, address of each delivery destination 2, remaining amount information and standard amount are compared, and the remaining amount A program for determining the information, a program for calculating the estimated time until the liquid runs out at the delivery destination 2 from the remaining amount information and the standard consumption of the liquid at the delivery destination 2, and the like are input in advance.
The reference amount may be uniform regardless of the delivery destination 2, but it is preferable to set the reference amount according to the liquid consumption amount for each delivery destination 2.
The standard consumption of the liquid at the delivery destination 2 is, for example, a value obtained by dividing the total consumption of the liquid within the predetermined period at the delivery destination 2 by the number of days in the predetermined period.

In this embodiment, the CPU functions as a determination unit and a delivery instruction unit. More specifically, the CPU extracts the remaining amount information and the reference amount from the memory, compares them, and determines whether or not the remaining amount information is equal to or less than the reference amount.
When the CPU determines that the remaining amount information is less than or equal to the reference amount, the CPU transmits instruction information including the name and address of the delivery destination 2 requiring liquid replenishment to the delivery vehicle 4 through a telecommunication circuit. , The delivery vehicle 4 is dispatched to the delivery destination 2.
Further, the CPU displays the instruction information on the screen of the computer 12, the driver and the delivery staff of the delivery vehicle 4 waiting at the delivery source 3 confirms the screen on which the instruction information is displayed, and the delivery vehicle 4 is displayed by itself. It can also be set to dispatch the vehicle to the delivery destination 2.
As described above, when the transmission unit 11 transmits the remaining amount information indicating that the remaining amount is equal to or less than the reference value, the computer 12 (CPU) is in the storage tank 10 when the remaining amount information is received. It may be determined that the remaining amount is equal to or less than the reference value, and the instruction information may be transmitted or displayed on the screen.

Further, when the CPU determines that the remaining amount information is equal to or less than the reference amount, the approximate amount of liquid replenishment is calculated from the remaining amount information and the capacity of the storage tank 10 (tank body 20) at the delivery destination 2. Then, the estimated time until the liquid runs out at the delivery destination 2 is calculated from the remaining amount information and the standard consumption of the liquid at the delivery destination 2, and these calculation results are included in the instruction information to the delivery vehicle 4. It can also be set to send. The program for executing the above calculation is input to the memory in advance.

When there are a plurality of delivery destinations 2 that require liquid replenishment, the CPU determines the delivery destination 2 from the estimated time until the liquid runs out at each delivery destination 2, the address of each delivery destination 2, the current position of the delivery vehicle 4, and the like. It is also possible to determine the vehicle allocation priority and the vehicle allocation route to the vehicle, and set to transmit the instruction information including the vehicle allocation route to the delivery vehicle 4.
Further, when a plurality of delivery vehicles 4 are running, the CPU travels the delivery vehicle closest to the delivery destination 2 based on the address of the delivery destination 2, the current position information of each delivery vehicle 4, and the like. It is also possible to set the instruction information to be transmitted to 4.

In the liquid delivery system 1 of the present embodiment, as described above, the liquid can be replenished in units of 1 liter, for example.
That is, in the present embodiment, the storage tank 10 can be replenished with an amount of liquid that is fully filled or an amount that is not fully filled.
Utilizing this point, for example, the determination unit can be set to execute the following determination based on the delivery destination information input in advance in the memory.
The delivery destination information is, for example, the address of the delivery destination 2, the remaining amount information for each delivery destination 2, the tank capacity of the storage tank 10 (tank body 20) for each delivery destination 2, the liquid consumption history for each delivery destination 2, and the like. be.
The liquid consumption history is, for example, a monthly data table of the past liquid consumption of the delivery destination 2.

First, the determination unit sets a group including a plurality of delivery destinations 2 based on the delivery destination information, and determines the liquid standard consumption amount for each delivery destination 2 from the liquid consumption history of each delivery destination 2 in the group.
The group may be set to include, for example, delivery destinations 2 located nearby based on the address of delivery destination 2, or may be set to include a plurality of delivery destinations 2 having similar liquid consumption histories. can.
The liquid standard consumption is, for example, a daily calculation of the liquid consumption in the same month as the delivery month in the liquid consumption history.
Next, the determination unit determines that the next replenishment time is approximately the same for all delivery destinations 2 in the group, based on the remaining amount information, tank capacity, and liquid standard consumption for each delivery destination 2. A unique liquid replenishment standard amount is determined for each delivery destination 2.
Here, the same period is, for example, in the range of 1 to 2 days, although it differs depending on the area area in the group and the like.

The liquid replenishment standard amount can be the actual replenishment amount as it is when the liquid consumption amount of the delivery destination 2 is almost constant, and the delivery destination 2 may consume a large amount of liquid irregularly or the delivery destination. When the liquid consumption of No. 2 tends to increase, it is preferable to add the correction amount to the liquid replenishment reference amount to obtain the actual replenishment amount.
The irregular mass consumption of the liquid at the delivery destination 2 is input to the memory as a part of the liquid consumption history.
In addition, the case where the liquid consumption tends to increase is, for example, the case where the liquid consumption in the three months before the delivery month has increased by 5 to 10% or more compared to the same month of the previous year, or before the delivery month. For example, when liquid consumption has been continuously increasing for 6 months.
The amount of correction varies depending on the delivery destination 2, but for example, it may be appropriately selected from the range of about 1 to 50 liters.
It is preferable that the liquid replenishment reference amount is not set to a constant value, but is calculated again by the CPU based on the above-mentioned delivery destination information for each replenishment opportunity.

The delivery instruction unit notifies the delivery vehicle 4 of the instruction information including the liquid reference replenishment amount set by the determination unit or by displaying it on the screen of the computer 12, and the delivery vehicle 4 is based on the notification. , Route delivery is performed to the delivery destination 2 of the group, and the liquid supply reference amount of liquid is injected into the storage tank 10 of each delivery destination 2.
Since the liquid replenishment standard amount is not necessarily the amount that fully fills the storage tanks 10 of all the delivery destinations 2, it may or may not be fully filled depending on the tank capacity of the delivery destination 2 or the standard liquid consumption. Can occur.
With such a setting, it is possible to improve the efficiency of route delivery of the delivery vehicle 4.

In the present embodiment, the computer 12 and the communication interface circuit connected to the computer 12 are used as the receiving unit, the determination unit, and the delivery instruction unit, but the present invention is not limited to this, and the same as the transmission unit 11 of the delivery destination 2.
