Description of the Related Art In a gas supply system for supplying a gas filled in a gas container (gas cylinder), a belt, a chain or the like is provided on a wall surface of a gas container installation portion such as a cylinder cabinet in order to prevent the gas container from falling over. The gas container fixing member is provided, and the gas container is fixed by the gas container fixing member.

On the other hand, in recent years, the use of various gases having different compositions by adding other component gases to a base gas has been increasing as a gas to be filled in a gas container. This tendency is remarkable. At this time, when the base gas is the same gas, the same gas container is usually used even if the types and addition amounts of the other component gases are different. For this reason, even if the composition of the filled gas is different, the external shape and coating color of the gas container itself are the same, and the type and shape of the container valve and the pipe connection are the same.

[0004]

Accordingly, in a gas supply facility for handling a plurality of gases having different types and amounts of component gases as described above, an empty gas container (empty container) is replaced with a new filled container (filled container). When the gas container is replaced with a filled container having a different gas composition, the gas supply pipe can be connected to the gas supply pipe as usual, so that a gas having a different composition is supplied.

[0005] In order to prevent such erroneous replacement of the gas container, a label specifying the gas name, composition, and the like is usually attached to these gas containers. However, it was difficult to completely prevent erroneous exchange.

Accordingly, an object of the present invention is to provide a gas container fixing device capable of reliably preventing erroneous replacement of a gas container by utilizing a gas container fixing member used for preventing a gas container from overturning. And

[0007]

In order to achieve the above object, a gas container fixing device according to the present invention is a gas container fixing device for preventing a gas container from overturning, in which a gas container body is fixed to a wall surface. The fixing member is provided with locking means for locking the fixing state of the gas container by the fixing member, and
A key member for locking or unlocking the locking means is attached to the gas container, and the type of gas to be filled in the gas container and the locking means are in one-to-one correspondence.

Further, in the gas container fixing device according to the present invention, the gas container has a storage portion for storing the key member, and the key member has a gas container corresponding to the type of gas to be filled. Is attached to the gas container via a string-shaped member having one end attached to the vicinity of the container valve, and when the length of the string-shaped member is fixed to a predetermined position by the fixing member, The key member attached to the gas container is set to a length that does not allow unlocking of the locking means, and the key member performs an unlocking operation of the locking means. The storage means has a function that, after performing the first unlocking operation, does not allow the second and subsequent unlocking operations, the locking means, By the key member corresponding to the lock means Be seen locked, the fixing member, the locking means is provided at one end, with the other end is formed of a rigid material mounted pivotably on the wall,
The attachment portion at the other end is provided with biasing means for rotating the fixing member in the locking direction of the locking means.

[0009]

1 and 2 show an embodiment of a gas container fixing device according to the present invention. FIG. 1 is a front view and FIG. 2 is a plan view. A fixing member 2 for fixing each of the gas containers B1, B2, and B3 to the wall surface 1 is provided on a wall surface 1 of a gas container installation portion such as a cylinder cabinet for accommodating a plurality of gas containers B1, B2, and B3. Is provided according to. The fixing member 2 is formed of a bendable member such as a normal belt or a chain. One end 2a is fixed to the wall surface 1 and the other end 2b is fixed to the wall mounting portions at both ends.
Locking means 3a, 3b, 3c are provided respectively.

The lock means 3a, 3b, 3c may be a normal lock, for example, a padlock. However, the lock means 3a-3c may be one type depending on the type of gas filled in the gas containers B1-B3. For one-to-one correspondence, locking means for locking / unlocking with the same key member if the type of gas is the same for the fixing members provided in other gas supply facilities and gas container installation parts. I have.

[0011] Further, when the locking means is locked,
A type in which a bar, a latch, a bolt, or the like is operated by hand or with a key member may be used, and a so-called auto-lock type using a latch in which locking is automatically performed and a key member is used only for unlocking is used. Such a thing may be used. Further, the locking means is not limited to the one provided on the wall mounting portion of the fixing member 2, and the fixing member 2 may be divided and the locking means may be provided at the divided part.

On the other hand, the lock means 3 is provided in each gas container.
An accommodating portion 5 for accommodating a key member 4 for locking / unlocking a to 3c is provided. This storage unit 5
For example, a suitable holding means which is fixed to the container valve portion by a suitable fixing means such as a belt or a chain so that the stored key member 4 does not fall off, for example, a spring for clamping the key member 4 is provided. ing.

The above-mentioned key member 4 is a key member 4 corresponding to the type of the charged gas stored in the storage portion 5 of the gas container and shipped at the filling factory. The key member 4 corresponding to the type of gas is always attached. This key member storage operation may be performed simultaneously with the pasting of a label in which the name of the gas, the composition, and the date of filling are conventionally performed.

In such a configuration, as shown in FIG. 1, when the gas container B1 of “C ₂ F ₆ ” is emptied and replaced with a new filled gas container (filled container) B11, The key member 4 is taken out of the storage portion 5 of the filling container B11, and the locking means 3a of the fixing member 2 fixing the gas container B1 is unlocked by the key member 4. At this time,
The locking means 3b on the “SiH ₄ ” side cannot be unlocked because the key member does not fit, and similarly, “C ₂ F ₆ ”
With a key member attached to a gas container filled with a gas other than the above, the lock means 3a of “C ₂ F ₆ ” cannot be unlocked.

Therefore, the locking means can be unlocked only when the empty container and the filling container are of the same type of gas, so that the gas container is accidentally replaced with a gas container filled with a different type of gas. Disappears. The key member 4 after the replacement of the gas container is stored in the storage portion 5 of the empty container and returned to the manufacturer or the like. By performing such a cycle, erroneous replacement of the gas container can be reliably prevented.

The means for attaching the key member 4 to the gas container is optional. For example, a ring-shaped hooking member may be attached to the key member 4 and hooked to the container valve portion. .

FIGS. 3 and 4 show preferred examples of the shape of the key member 4. FIG. The key member 4 is provided with a plurality of notches 6 and notches 7 corresponding to locking means on a plate-shaped member, and is similar to a plate-shaped key used for a so-called bath lock. Things. By using such a plate-like key member 4, the type of gas corresponding to the lock means 3 that locks / unlocks using the key member 4,
For example, as shown in FIG. 3 and FIG.
In the case of a gas containing 0% silane, “20% SiH ₄ / H
e _", in the case of C ₂ F 6 100% may have been described the display such as" _C 2 _{F 6} ", clearly with a relatively large characters. Therefore, not only the unlocking operation of the lock means but also the confirmation of the key member at the filling factory can be easily performed, and the management of the key member 4 is also facilitated.

Further, it is not necessary to use the same type of lock means 3 and key member 4 for all gas types. For example, the above-mentioned bathhouse lock and padlock are used for the adjacent fixing member 2. Is also good. Further, the key member may be of an electronic type (electric type, magnet type, optical type, etc.). In this case, the key member is provided with a storage circuit for storing that the locking means has been unlocked, and after performing the first unlocking operation,
By adding a function that disables the unlocking operation for the second and subsequent times, unauthorized use of the key member can be prevented.

FIG. 5 shows another embodiment in which the key member 4 is attached to the gas container B. The key member 4 includes a string-shaped member having one end attached to the vicinity of a container valve of the gas container B,
For example, the key member 4 does not reach the lock means 3 when the gas container B is fixed at a predetermined position by the fixing member 2 because the wire 8 is fixed to the gas container B via the wire 8. Set to length.

Therefore, when replacing the gas container B, the locking means 3 is unlocked using the key member attached to the new filling container. The unlocking operation at this time is
It can be performed by using the height of the pedestal of the cylinder cabinet in which the gas container B is installed, or by using the inclination of the gas container placed obliquely on the cylinder carrier. It can also be performed by tilting to the third side. In any case, when the type of gas is different, the locking and unlocking of the locking means 3 cannot be performed as described above, so that erroneous replacement of the gas container can be reliably prevented.

As described above, the gas container is exclusively used for a specific gas, and the key member 4 corresponding to the gas container is fixed to the gas container, thereby preventing the key member 4 from being erroneously attached or lost.

FIG. 6 shows that the fixing member 2 is formed of a rigid material such as a metal such as stainless steel or aluminum.
The lock means 3 provided at one end is of an automatic lock type, and a biasing means for rotating the fixing member 2 in the locking direction of the lock means 3 is provided on the wall mounting portion 2b at the other end. As the urging means, a normal coil spring or the like can be used, and as a whole structure, for example, a structure similar to a lock device used for an umbrella stand can be adopted. With such a configuration, the locking of the locking means 3 after the replacement of the gas container B can be automatically performed.

The gas container fixing device of the present invention can be applied to a gas supply facility which handles only one kind of gas, and can cope with an erroneous delivery of a gas container.

[0024]

As described above, according to the gas container fixing device of the present invention, erroneous replacement when replacing the gas container can be reliably prevented.
