Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an entire fuel draining device for separating and collecting residual fuel from a fuel tank of a discarded automobile. The illustrated device is a device that is attached to a dismantling line (not shown) for dismantling an end-of-life vehicle and removes residual liquid, particularly fuel during pretreatment. A base fuel drainer is assigned. Needless to say, the illustrated fuel draining device can be installed separately from the dismantling line, and can be used and profited independently. As used herein, the term “disused car”, that is, the term “disused car (SC)” refers to a discarded car from the beginning,
The concept includes all vehicles that can be used but are obsolete, such as new models under research and development.

[0007] The fuel draining device 1 is designed so that an operator can use a floor (F.
L.) In order to be able to work in a standing position, the vehicle has a steel gantry 3 having an upper surface portion on which a scrap car (SC) that is higher than the floor can be mounted correspondingly.
Although it is assumed that the scrap car (SC) is mounted on the upper surface of the gantry 3 by a forklift, another loading device (not shown) such as a crane may be used.

A puncturing device 11 is provided in the gantry 3 for piercing a fuel drain hole in a fuel tank on the bottom of a waste vehicle. As can be understood from FIGS. 2 and 3, puncturing device 1
1 is movable in the Y direction by engaging four free rollers 15 such as pulleys of the self-propelled portion 13 attached to the substantially center thereof with a pair of horizontal vertical rail members 19 of the bogie portion 17, In addition, four free rollers 21 such as pulleys at both ends of the vertical rail member 19 of the bogie unit 17 are engaged with a pair of horizontal rail members 23 installed on the floor (perpendicular to the Y direction) to make X. It can move in any direction. In other words, the puncture device 11 can be easily and easily translated in two horizontal directions of XY by an operator's force to a lower position corresponding to the position of the fuel tank on the bottom of the waste vehicle on the gantry. It is configured.

The puncture device 11 includes (i) a puncture tool 31 made of, for example, a sharp-pointed harpoon-shaped fitting for making a fuel drain hole in the fuel tank, and (ii) a puncture tool 31. A pneumatically actuated first cylinder device (first drive device) 33 that moves up and down in the vertical direction, and (iii) puncturing tool 3
1 and a fuel receiving container 35 having an open upper part,
v) A bellows-like seal member 37 made of, for example, rubber, which can hermetically and liquid-tightly seal an annular contact portion between the opened upper portion of the fuel receiving container 35 and the fuel tank, and the element (i) above (v)
-(Iv) is a second type of pneumatically operated type that moves up and down as a whole.
And a cylinder device (second drive device) 39.
The two cylinder devices 33 and 39 are of a pneumatic type from the viewpoint of ease of handling and less inconvenience of leakage. However, from the viewpoint of operation stability, controllability, high output, and the like. A hydraulic (hydraulic) operation type can also be used.

At the base side of the puncture tool 31 of the puncture device 11, a ground wire 41 for discharging electric charge is provided at the base side of the puncture tool 3 in order to reduce an electric spark which is likely to be generated when a hole for discharging fuel is formed.
Considering one vertical movement stroke, they are electrically and mechanically connected with a certain slack. Puncture device 11
The fuel receiving container 35 is preferably made of a transparent or translucent resin-made cylindrical material whose inside can be seen.

The fuel receiving container 35 has an inert gas (specifically, a carbon dioxide gas or a nitrogen gas) at least at a location where the puncture tool 31 pierces the fuel tank being hermetically sealed by the bellows-like sealing member 37. And the like, and a nozzle device (inert gas supply device) 43 connected to an inert gas source (not shown) is provided in order to suppress the generation of sparks (ignition of residual fuel) by injecting and filling sparks. .

In order to measure the specific gravity of the fuel that falls and accumulates in the fuel receiving container 35, for example, a float type hydrometer (specific gravity measuring means) including a transparent cylinder and a float is used. 45 is provided so that the state can be visually recognized from the outside. Further, the fuel receiving container 35 has, for example, a three-port, three-position closed center for switching a piping path for guiding accumulated fuel to a collection tank (that is, a gasoline collection tank and a light oil collection tank (not shown)) corresponding to the specific gravity. A manual-type directional switching valve 47 of a type is additionally provided. The manual directional control valve may be configured to be easily operated by an electric switch near the operator instead of the electromagnetically operated type. In addition to this modified configuration, the specific gravity measuring means includes, for example, a differential transformer capable of electrically detecting the liquid level displacement, and an electronic control capable of identifying the specific gravity of the fuel, and thus the type of fuel, based on the detection signal. It is also possible to automatically control or semi-automatically control the switching of the piping path by configuring the apparatus so as to include the apparatus.

The actual operation of the fuel draining device of the present embodiment having the above configuration will be briefly described below. First, the operator moves the puncture device 11 in the X and Y directions to a position below the bottom surface of the waste vehicle (SC) set on the gantry 3 corresponding to the position of the fuel tank.

Next, by operating an operation switch (not shown), the second cylinder device 39 is operated to raise the first cylinder device 33 and the fuel receiving container 35 above the first cylinder device 33, and the bellows-shaped upper opening of the fuel receiving container 35 is opened. Seal member 3
7 is brought into contact with the fuel tank. Next, the puncture tool 31 is raised by the operation of the first cylinder device 33, but before or at the same time, the nozzle device 43 injects and fills a pierced portion with an inert gas to suppress spark generation. The rise of the puncture tool 31 causes a hole in the fuel tank, and stops or delays the rise of the puncture tool 31 while the diameter of the hole being formed is small. Housed in Then, whether the fuel is gasoline or light oil is discriminated by the specific gravity meter 45 attached to the fuel receiving container 35.

Next, by switching the direction switching valve 47, the fuel receiving container 35 and the corresponding recovery tank are connected in a flow path. Next, the puncture tool 31 is further raised to penetrate the tank bottom wall, and then the puncture tool 31 is lowered. At this time, the widened stepped portion on the base side of the puncture tool 31 deforms the peripheral portion of the hole downward like a funnel (funnel / funnel), thereby making it difficult for fuel to stay inside the tank, and The fuel flows out (falls) without leaving the fuel in the container.

Thus, the residual fuel in the fuel tank is
The fuel is reliably collected in the corresponding collection tank via the fuel receiving container 35 through the hole. As described above, in the present embodiment, it is possible to easily and simply and safely make a hole in the tank in which the fuel remains, and easily identify what kind of fuel the fuel is in during making the hole. As a result, it is possible to appropriately and promptly collect in the collection tank. Thereby, workability, efficiency, and the like of the fuel removal operation can be dramatically improved.
