JP2003118579A - Carrier for conveying vessel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To dispense with reloading work in a front room of a dustproof room and to suppress dust generation from a carrier and a vessel in conveying a relatively heavy vessel of liquid, gas, or the like from the outside to the dustproof room. SOLUTION: A space is disposed under a vessel loading part of the carrier, and an upper loading plate for loading the vessel is provided with an opening in a place corresponding to the bottom of the vessel. A suction port for suction in the space is provided. In carrying the vessel into the dustproof room, dusts adhered to the bottom of the vessel are sucked via the opening and the space by the suction in the space from the suction port. Thus, the bottom of the vessel can be cleaned while being loaded on the carrier, though this is conventionally difficult.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carriage for transportation, and more particularly, to a container such as a canister containing an irregularly shaped object such as gas, liquid, or powder, which has a cleanliness level of a general level and a dust-proof chamber level or higher. The present invention relates to the structure of a dolly for carrying to and from a clean environment.

[0002]

2. Description of the Related Art Conventionally, when a canister container or the like containing an irregular shape such as a liquid chemical is carried into a dustproof room or a clean room from the outside, a canister container has a carry-in port. It is a general method that the container is transported to the front chamber, washed with high-pressure air, and then transferred to a dust-proof chamber or a clean room after the container is placed on a carriage or the like dedicated to loading.

[0003]

However, in the above method, a remounting work in the antechamber occurs, and particularly when the object to be transported is a heavy load, a lot of manpower or equipment for the remounting is required. Is required, and a lot of costs are required. In addition, accidents such as injuries during moving work may occur.

At the same time, since it is difficult to blow air with such a heavy object in a lifted state, the dust adhering to the bottom of the container cannot be removed. It scatters and causes a decrease in cleanliness in the room, which causes failure of products manufactured indoors.

The object of the present invention is to carry a particularly heavy container, such as a canister, which can be easily cleaned without leaking and can be carried into a dustproof chamber without having to replace the container between vehicles. To provide a dolly.

[0006]

The carriage of the present invention comprises:
At least, it has a loading section for loading containers,
The stacking unit, an upper stacking plate for mounting the container,
There is a space surrounded by a lower support plate and a side wall provided between the upper loading plate and the lower supporting plate, and at least a part of a portion of the upper loading plate corresponding to the container loading position is provided. An opening communicating with the space above the loading section and the space is provided, and a suction port for sucking the space is provided in any of the upper loading plate, the lower support plate, and the side wall. It is characterized by being.

According to the present invention, the container bottom, which has been difficult to clean conventionally, is sucked from the suction port via the opening and the space provided in the upper stacking plate, so that the cleaning can be achieved. . Moreover, since the trolley can be cleaned as it is, it is not necessary to replace the trolley in the front chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [Embodiment 1] FIG. 1 is a schematic sectional view of a carrier truck according to a first embodiment of the present invention. In the figure, 1 is an upper loading plate for loading containers 8, 2 is a lower supporting plate, 3 is a side wall, and a space 9 is surrounded by the upper loading plate 1, the lower supporting plate 2 and the side wall 3. Further, the upper stacking plate 1 is provided with an opening 6 at a position corresponding to a part of the bottom portion 8A of the container 8 when the container 8 is installed. further,
The side wall 3 is provided with a suction port 7 connected to the space 9.
Reference numeral 5 is a handle used for transportation, and has a structure that can be attached to and detached from the main body of the carriage, which is not shown.

The operation of the truck is as follows. (1) The container is stored or temporarily placed in a storage or the like while being placed on a trolley. At this time, by removing the handle 5, the occupied area can be saved and the utilization efficiency of the storage location is improved. (2) Attach the handle 5 at the time of unloading and transport it as a trolley to the front chamber of the dustproof chamber. (3) High pressure air is blown to clean the surfaces of the container 8 and the carriage. (4) A suction hose such as a vacuum cleaner is connected to the suction port 7 (not shown) to suck the inside of the space 9. As a result, the dust attached to the bottom portion 8A of the container 8 is sucked through the opening 6 and the bottom portion 8A of the container is cleaned. (5) Bring the trolley as it is into the dustproof room, and install it as it is at the container installation location. (6) After the container is empty, carry it out as a cart.

In the dolly to which the present invention is applied, the number of dusts around the container in the dustproof chamber is reduced to about half of that in the conventional carrying-in method.

In this embodiment, the handle 5 has a detachable structure, but it may have a fixed structure or a foldable structure that is not removable.

[Embodiment 2] FIG. 2 is a schematic sectional view of a carrier truck according to a second embodiment of the present invention. In the first embodiment, the stain on the contact portion 10 of the container bottom portion 8A with the upper stacking plate 1 could not be removed even by air blowing from the outside and suction from the suction port 7. In this embodiment, a suction plate 11 having an adhesive surface is provided at a position of at least a portion 10 of the upper stacking plate 1 that comes into contact with the container. As a result, it is possible to significantly suppress the generation of dust due to the dirt on the contact portion. The suction plate 11 may be a non-reusable sheet-peel type adhesive mat or a reusable adhesive rubber. In the sheet-peel type mat, by peeling the sheet each time it becomes dirty, the adhesive rubber In this case, it is possible to maintain the cleanliness by washing as needed.

[Embodiment 3] FIG. 3 is a schematic cross-sectional view of a carrier truck according to a third embodiment of the present invention. In this embodiment, in addition to the truck of the first or second embodiment, the container bottom 8A is further added.
Nozzle 12 for blowing gas to the nozzle and its nozzle 1
Attachment 1 for connecting 2 to the gas pipe from the outside
3 is added.

In operation, in the antechamber, a gas pipe for supplying clean air, nitrogen or the like is connected to the attachment 13 (not shown), and the nozzle 12 is connected to the bottom 8 of the container.
At the same time that the gas is blown to A, a suction hose (not shown) is connected to the suction port 7 to suck the inside of the space 9.

According to this embodiment, gas is blown to the bottom 8A of the container, and the blown dust is sucked from the suction port 7 at the same time, so that the cleanliness can be further improved.

The shape of the nozzle 12 is not limited to the simple one shown in FIG. 3, but a plurality of jet outlets are provided on radially branched branches or concentric circles so that the bottom surface 8A can be widely sprayed. Various things are conceivable, such as a pipe provided with a plurality of ejection ports, a pipe provided with a large number of ejection ports on a spherical surface, and the like.

Further, although the suction plate 11 described in the second embodiment is not shown in FIG. 3, it is naturally applicable.

[0018]

According to the present invention, it is possible to easily clean the bottom of a heavy container, which has been difficult to clean conventionally, and to suppress dust generation in the dustproof chamber or the clean room. Further, since the entire trolley can be cleaned, it is not necessary to replace the trolley on the pedestal in the front chamber of the container, which can reduce the man-hours and equipment costs for the remounting, and can reduce the occurrence of accidents during the remounting.
