Description

INDUSTRIAL APPLICABILITY The present invention is a detectable tool suitable for a fuel oil distribution system that prevents oil mixing that accompanies the work of loading fuel oil onto a tank truck at an oil depot and unloading the loaded fuel oil into an oil storage tank at a service station. Regarding.

Tank trucks, which are responsible for delivery from oil depots to refueling stations, store gasoline,
When loading oil types such as light oil and kerosene without mixing them up, and when unloading into underground tanks at gas stations, we mix oil in order to unload fuel oil from each hatch into an underground tank for each oil type. It is necessary to prevent

For this reason, when loading tank trucks at oil depots, in order to prevent the loading of a different type of fuel oil from the desired oil type into each hatch of the tank truck and the occurrence of overflow, For example, a tank lorry vehicle described in Patent Document 1 has been proposed.
Further, in order to prevent oil from being mixed or overflowing when unloading from a tank truck to an underground tank at a gas station, for example, a tank truck control device described in Patent Document 2 has been proposed.

These inventions are effective, but the tools to be detected during loading at oil depots are hatch numbers, and the tools to be detected when unloading at gas stations are underground tank numbers and oil types. In fuel oil delivery systems, which are on the rise, there is a need to collate additional information, and there is a problem that the amount of information is insufficient only with conventional magnetic devices to be detected.

JP-A-7-172493 JP-A-1-226592

The present invention has been made in view of such problems, and its object is to improve the efficiency of management of loading at an oil depot and unloading at a service station. An object of the present invention is to provide a device to be detected of a system, particularly a device to be detected that is suitable for a reader disclosed in Japanese Patent Application No. 2019-088820.

In order to achieve such a task, the present invention provides a detector at each hatch of a loading arm or tank truck at an oil depot, and a device to be detected at each hatch or loading arm of the tank truck, so that the detector is connected to the detector. In addition to inserting a device to be detected to prevent erroneous loading, a detector is provided in the unloading hose of the lorry, and a device to be detected is provided in the oil filling port that communicates with the oil storage tank of the filling station, and the device to be detected is connected to the detector. In the detection tool of the mixed oil prevention device that inserts the detection tool to prevent erroneous unloading,
The object to be detected has a storage recess formed in a main body housing made of metal. An IC tag sensor unit is housed and fixed in the storage recess by resin sealing. A lid portion made of resin that is below the surface is provided.

According to the present invention, the amount of information that can be stored can be increased, and the information stored in the IC tag sensor unit can be output by reliably transmitting radio waves with the resin cover. improves.

FIG. 2 is an exploded view showing an IC tag sensor unit storage area of an embodiment of a device to be detected according to the present invention; The figure which shows one Example of the to-be-detected tool of this invention in the state which removed the cover part of the IC tag sensor unit storage part. The figure which shows the external appearance of one Example of the to-be-detected tool of this invention.

Therefore, the details of the present invention will be described below based on the illustrated embodiments.
In FIG. 1, a main body housing 2 made of metal that can be inserted in the direction of an arrow 1 has a housing recess 4 in which an IC tag sensor unit 3 is built in at the tip side in the direction of insertion. A resin cup 5, a magnetic sheet 6, and an IC tag sensor unit 3 are stacked in order from the lower side to the opening side of the body housing 2 in the housing recess 4, and resin is poured from above them. A lid portion 7 made of resin, which is lower than the upper surface, is pushed in and finally fixed to the main body housing 2 with a plurality of screws 8 so that the whole is accommodated and fixed.

In the completed state, the upper surface of the lid portion 7 is below the surface of the main body housing 2 as shown in FIG. 3, so smooth insertion into the tag reader is guaranteed.

The IC tag sensor unit 3 is housed in a resin cup 5 surrounded by a magnetic sheet 6 with only its upper surface exposed.

A plurality of claws 7a are provided on the outer periphery of the lid 7 made of resin, and on the inner peripheral surface of the storage recess 4, there are receptacles that engage with the claws 7a when the lid 7 is loaded in the normal position and posture. A part (not shown) is formed.

A projection 5a is formed on the back surface of the resin cup 5 (the surface facing the housing recess), and a recess 4b is formed on the bottom surface of the housing recess 4 at a position that meshes with the projection 5a when the resin cup 5 is properly loaded. there is

As a result, the resin cup 5 and the IC tag sensor unit 3 accommodated therein
can be relatively accurately positioned and fixed to the body housing 4 . Although the projection 5a is provided on the resin cup and the recess 4b is provided on the storage recess 4 in the above embodiment, the resin cup 5 may be provided with a recess and the storage recess 4 may be provided with a projection.

The unevenness of the resin cup 5, the unevenness of the housing recess 4, the claw portion 7a of the lid portion 7 made of resin, the magnetic sheet 6, and the lid portion 7 allow the IC tag sensor unit 3 to be positioned and accommodated at a prescribed position in the main body housing 2. can do

Further, a recess 4a into which the filled resin flows is formed in the inner surface of the storage recess 4, and the filling resin flows into the recess 4a and is fixed. As a result, the IC tag sensor unit 3 can be accurately positioned and fixed in the storage recess 4 of the main body housing 2 as a waterproof structure that prevents water from entering from the outside.

Since the IC tag sensor unit 3 is accommodated and fixed in the storage recess 4 of the main body housing 2 made of metal with the magnetic sheet 6 interposed on the main body housing 2 side, the magnetic sheet 6 separates the IC tag sensor unit 3 from the main body housing. The information of the IC tag sensor unit 3 can be stably read out by eliminating the radio wave interference with the metal constituting the IC tag sensor unit 2 and by stabilizing the magnetic flux to prevent the influence of the main body housing made of metal as much as possible.

The main body housing 2 is formed with a non-slip groove 9 on the side surface of the rear end in the direction of insertion, a hole 10 through which a string for attachment to each hatch or loading arm of the tank truck is passed, and an arrow 11 indicating the direction of insertion. It is Due to the presence of the groove 9, the tag can be easily and simply attached to the reader even while wearing work gloves, and workability can be improved.

A nameplate 12 describing the type of oil can be attached to the surface of the body housing 2 as needed. As a result, a field worker can easily obtain general information by visual inspection without going through the device.
