[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kerosene vending machine and a dedicated container used in combination with the vending machine.

[0002]

2. Description of the Related Art Conventionally, kerosene has been retailed by various companies such as gas stations, liquor stores, and miscellaneous goods businesses.
The sales form is manned, either by the vendor delivering kerosene-filled cans, or by the vendor weighing and filling kerosene into a container brought by the purchaser and receiving a price commensurate with the metered amount. Was.

On the other hand, with the liberalization of imports of petroleum products, it is expected that sales channels for petroleum products will be diversified, sales competition will intensify, and sales prices will decrease. At that time, the reduction of labor-related labor costs, which had been added to the selling price in the past, is an important theme, and the unmanned sales of gasoline and other products in Europe and the United States will spread to Japan in the future, which will affect the sales of kerosene. Is also expected to extend.

[0004] However, in the unmanned sale of kerosene, which is a dangerous substance, it is not merely necessary for the purchaser to perform the refueling operation, which has been conventionally performed by the seller, and even ordinary customers can safely and easily handle the refueling operation. Unmanned sales equipment is required. Until now, however, there has been little need for equipment for unmanned kerosene sales, and such equipment has not been developed in practice.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a kerosene vending machine which can be safely and easily handled by a general customer himself, and a special container used in combination with the vending machine.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventor has found that a kerosene receiving container having a single shape and capacity is used to simplify the mechanism of a vending machine. The present invention was completed based on the idea that it is advantageous to perform quantitative sales using this and the idea of its related functions.

Thus, according to the present invention, (1) a vending machine for receiving kerosene and supplying kerosene to a dedicated container, wherein a quantitative function for automatically stopping every time kerosene for one container is pumped from a tank outside the machine. With pump
An oil supply nozzle connected to the pump by a flexible pipe and a sensor nozzle provided with a detection end of each sensor for detecting a residual oil amount and a residual oil type in a dedicated container are attached to a horizontal member so as to face downward. A nozzle block, a container storage space provided below the nozzle block, a fireproof shutter for shutting off the storage space from the outside, and determining whether a container placed on the floor in the storage space is a dedicated container. The container is identified based on the external dimensions of the container, and when the container is recognized as a special container, a container fixing arm for fixing the container at a predetermined position, and whether or not the container is a special container is determined by the shape and position of the lid of the container. Further, based on the above, when the container is recognized as a dedicated container, a lid opening arm for opening and closing the lid of the container, the nozzle block is moved under the ground, and the tip of each nozzle is inserted into the opening of the container. A kerosene vending machine comprising: a nozzle elevating device to be detached; and a cash automatic payment and dispensing device for issuing a start command to the pump when a predetermined price is received and a predetermined safety is confirmed. A kerosene receiving container used in combination with the vending machine described in the above item (1), a predetermined outer dimension for container identification by the container fixing arm, and two openings adapted to the respective nozzles; And a lid having a shape that fits into the hole of the grip at the tip of the lid opening arm.

The kerosene vending machine according to the present invention (hereinafter referred to as "the machine") enables the unattended sale of kerosene by the purchaser's own operation and payment. In this machine, a dedicated container having a predetermined size, structure, and capacity is used in order to simplify a mechanism for performing various safety checks.

[0009] Basic items to be ensured for safety in the machine are: a) confirmation of whether or not the container placed in the machine is a dedicated container, and b) whether or not there is residual oil in the container. And c) confirmation of whether or not the residual vapor in the container is kerosene. If the answer to these confirmations is no, kerosene will not be sold.

[0010] The supply of kerosene by the present machine is performed by inserting a refueling nozzle into one of the openings of the container, and the confirmation of the above b and c is performed by inserting the sensor nozzle into the other opening of the container. Since these operations are performed, these operations cannot be guaranteed for containers other than the dedicated containers. Therefore, it is necessary to confirm whether the container placed in the apparatus is a dedicated container as described in a) above. This confirmation is performed twice through the operation of the container fixing arm and the lid opening arm.

[0011] The confirmation of whether there is no residual oil in the container in the above-mentioned b) is performed to ensure the receiving side capacity which does not overflow even if a predetermined amount of kerosene is dispensed from the fixed amount supply pump, and c). The confirmation of whether or not the residual steam in the container is kerosene is performed in order to avoid the danger of mixing low-boiling oil such as gasoline in kerosene.

Hereinafter, the basic operation of the apparatus will be described step by step. First, when a predetermined price is paid to the automatic cash settlement / payout device, the fire shutter is opened and a series of operations is started. The fire shutter is made of a non-combustible material such as a metal and always shuts the inside and outside of the apparatus. This machine's automatic payment
As the dispensing device, for example, a known device disclosed in Japanese Patent Publication No. 49-36440 can be used. Also,
A card reader may be provided to enable the use of a prepaid card or a credit card. In addition, since this machine only supplies a fixed amount to a special container in principle, it is not necessary to set the refueling amount and display the sales volume and amount each time. It becomes possible to do.

When the fireproof shutter is opened, a container housing space for placing a kerosene receiving container appears below the nozzle block, and the kerosene purchaser places the brought container on the floor in the space. When the container is placed, the fire shutter closes and the container is held and fixed at its bottom by two container fixing arms. At this time, if the final distance between the container fixing arms is different from the predetermined value, the container is determined to be other than the dedicated container, and the acceptance is rejected.

When the fixing of the container is completed, the two lid-opening arms which have been waiting at the position where they are not in the way are actuated to find the two lids of the exclusive container, and turn the screw-type lid to remove it. At this time, if the lid opening arm cannot find the lid at the predetermined position, or if the shape of the hole of the grip at the tip of the arm does not match the shape of the lid and it can not fit into the lid, the container is dedicated It is determined that the container is not a container, and is rejected.

When the opening of the lid is completed, the nozzle elevating device operates to move the nozzle downward, and the refueling nozzle and the sensor nozzle are inserted into the two openings on the upper surface of the dedicated container. Then, the confirmation items b and c described above are executed.

If there is no problem in confirming b and c, a start command is issued from the automatic cash settlement / dispensing device to the fixed-rate supply pump. After a predetermined amount of kerosene is supplied to the dedicated container through the refueling nozzle, the pump is automatically stopped, and the nozzle elevating mechanism operates to raise the nozzle upward. Subsequently, the lid opening arm is operated again to attach the two lids to the dedicated container, the container fixing arm is opened to release the container from the fixed state, and the fire shutter is opened to allow the container to be taken out. In this case, for example, a constant displacement pump may be used as the constant-rate supply pump, and the pump may be controlled so that the power is automatically cut off when the number of revolutions after startup reaches a predetermined value.

In the above description, the lid of the exclusive container has a shape corresponding to the shape of the hole of the grip at the tip of the lid opening arm, but it is necessary to reduce the chance that the lid coincides with the lid of a container other than the exclusive container. It is desirable to avoid simple circles and the like. If a transparent window for confirming the amount of oil is provided on the side of the container, it is convenient for a kerosene purchaser to confirm the amount of oil.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention include the following (3) to (6). (3) an in-machine oil storage tank having the same capacity as a dedicated container is provided between the pump and the refueling nozzle, and the refueling nozzle is provided with an automatic valve;
When the prescribed price is received and the prescribed safety confirmation is made,

Vending machine.

In the present embodiment, an in-machine oil storage tank as an intermediate tank is added between the fixed-rate supply pump and the oil supply nozzle. When kerosene is supplied directly from the metering supply pump to the dedicated container, the capacity of the pump must be increased in order to shorten the supply time. However, when the oil storage tank is used to supply oil to the oil storage tank in advance using the idle time of the machine, the pump capacity may be small.
The oil storage tank may be provided integrally with the nozzle block. By doing so, the oil supply nozzle protrudes directly from the bottom of the oil storage tank, reducing the pipe resistance,
Dispensing time is reduced.

When using the oil storage tank of the present embodiment,
It is necessary to slightly change the control method of this machine. That is, it is necessary to provide a valve for the oil supply nozzle in order to always keep the outlet of the oil storage tank closed. This valve must be an automatic valve because it is opened and closed by remote control from a cash automatic payment and dispensing device. When this valve opens, the kerosene in the oil storage tank is dispensed to a special container, and after a certain time, the oil storage tank is emptied. To refill the oil storage tank with kerosene, it is necessary to close the valve and give a start command to the fixed-rate supply pump.

(4) Instruction means for instructing insertion of a container into the storage space, a container sensor for detecting the container, a timer for measuring the time from the instruction to container detection, A shutter opening / closing mechanism for opening and closing the fire prevention shutter in response to a signal;
Or the kerosene vending machine according to (3).

When a predetermined price is paid to the automatic cash settlement / payout device of the machine, a fire shutter is opened and a series of operations is started. At this time, it is desirable to instruct insertion of the container by an instruction means such as a display panel or an audio device. In this state, if there is no insertion of the container even after waiting for a certain period of time, it is preferable from the viewpoint of safety that the user does not intend to purchase and closes the fire prevention shutter. The timer of the present embodiment measures the elapsed time during that time. If the container is inserted within a certain period of time, a normal process should be started, so that the fireproof shutter needs to be closed immediately. The above-mentioned container sensor detects that a container has been inserted for that purpose.

(5) The sensor for detecting the residual oil amount is a liquid level sensor using a float hanging down from the tip of the sensor nozzle, and the sensor for detecting the residual oil type includes an intake pipe opening in the sensor nozzle. The kerosene vending machine according to the above (1) or (3), which is a vapor sensor having:

In accordance with the present embodiment, residual oil amount detection sensor, for example a float may be designed to detect the residual oil liquid surface by, in this case, the float is provided in the form of hanging from the tip of the sensor nozzle, The sensor body is desirably provided on a vertical earth side of the sensor nozzle. Further, as the residual oil type detection sensor, a vapor sensor using a known ultrasonic propagation time method, a contact combustion method, a semiconductor chemical adsorption method, or the like can be used. It is desirable that an intake pipe that collects the vapor in the container and sends it to the vapor sensor main body is also opened in the sensor nozzle.

[0025] (6) by refluxing kerosene between said outboard of tank and the oil storage tank, kerosene vending machine of the above (3) wherein the always kept below a specified value the temperature of the oil storage tank.

The present invention is not limited to the possibility of being installed outdoors in a place where direct sunlight is strong. However, when the in-machine oil storage tank is employed as in the embodiment (3), there is a possibility that kerosene vapor may fill the inside of the machine particularly when the temperature of the oil storage tank increases in summer. In order to avoid this danger, it is desirable to provide a certain temperature control device and always keep the temperature of the oil storage tank below a specified value. As the type of the temperature control device, besides the one using a normal refrigerant, as in the embodiment (6), kerosene is intermittently interposed between an outside tank and an oil storage tank which maintain a substantially constant temperature, for example. It is possible to control the temperature by refluxing.
