Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a carton used for sending out radioactive solid waste in a carton box, which is generated, for example, from a nuclear research facility, to an incinerator or the like one by one. The present invention relates to a transportation device for miscellaneous solids in a box.

(Prior Art) Generally, radioactive miscellaneous solid waste is packed in polyethylene bags and sent to incinerators, but in nuclear research facilities, there is a possibility that waste containing liquid will be generated, The waste is put in a waterproof paper bucket carton box, and the outside of the carton box is wrapped in a polyethylene bag and sent to an incinerator or the like as a crude solid in a carton box.

Since it is necessary to sequentially load one such carton box-containing miscellaneous solids into the incinerator one by one, conventionally, an operator manually placed it on a conveyor for loading, but for this reason, manpower is required all day long. In addition, there is a problem that the possibility of radiation exposure is not zero because long-term radioactive solid waste is handled.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems of the related art, and the carton can be automatically sent to the incinerator or the like one by one without the need for manpower. It has been completed to provide a carrier for miscellaneous solids in a box.

(Means for Solving the Problems) The present invention made to solve the above problems is to provide a wide stock conveyor that intermittently transfers a plurality of carton box-containing miscellaneous solids in a plurality of rows at a constant pitch. , A single-row conveyor that is provided at a right angle below the tip of this stock conveyor and has partition bars with a constant pitch on its surface, and is installed between the tip of the stock conveyor and the single-row conveyor. A guide chute provided with a vertical partition wall for guiding the cartons box-containing miscellaneous solids to be overturned and simultaneously falling onto the single-row conveyor.

(Example) Hereinafter, the present invention will be described in more detail with reference to the illustrated example.

In the figure, (1) is a wide stock conveyor having a width of about 1 m and a length of about 6 m, for example. In the embodiment, the stock conveyor (1) is divided into three rows by the guide rails (2), and the carton box-containing miscellaneous solids (3) are placed in three rows.

The miscellaneous solid (3) contained in a carton box is a shape in which radioactive waste is stored in a paper bucket-shaped carton box whose inner surface is waterproofed and the outer side is wrapped in a polyethylene bag as described above. For example, the diameter is about 30 cm and the height is about 35 cm. Such miscellaneous solids (3) in a carton box are arranged at a constant pitch along partition bars (4) projecting at a constant pitch on the surface of the stock conveyor (1). Although only the three frontmost rows are shown in FIG. 1, they are arranged in three rows at a constant pitch over the entire length of the stock conveyor (1). The stock conveyor (1) intermittently advances by the pitch of the partition bars (4).

(5) is a single-row conveyor provided below the tip of the stock conveyor (1) in a direction perpendicular to the stock conveyor (1). This single-row conveyor (5) is also provided with partition bars (6) with a constant pitch on its surface, and guides (7) for preventing fall are provided on both sides. The width of the single-row conveyor (5) is dimensioned so that the miscellaneous solids (3) contained in the carton box can be conveyed in a state of being laid sideways as shown.

(8) is a guide chute installed between the tip of the stock conveyor (1) and the single-row conveyor (5). In this guide chute (8), the miscellaneous solids (3) containing carton boxes in each row sent from the stock conveyor (1) fall onto the single-row conveyor (5) while rolling over at the tip of the stock conveyor (1). This is for guiding the operation and is provided with a vertical partition wall (9) inside the box whose side surface and lower surface on the stock conveyor (1) side are open.

(Operation) The operation of the transporting device of the present invention thus configured is as follows.

First, at the start of work, a large number of miscellaneous solids (3) in carton boxes are arranged along the partition bars (4) on the stock conveyor (1) in a plurality of rows (3 rows). The stock conveyor (1) is preferably sized so that it can carry the carton box-containing miscellaneous solids (3) in an amount that can be incinerated a day. Although this work can be performed by a robot or manually, the work can be completed in a relatively short time even when manually performed.

Next, when the stock conveyor (1) is moved forward by one pitch, the carton box-containing miscellaneous solids (3) at the tip of the stock conveyor (1) are guided by the vertical wall (9) of the guide chute (8) to form three solids. At the same time, it falls and is stored in a horizontal state between partition bars (6) of a single-row conveyor (5) provided at right angles below the tip of the stock conveyor (1). At this time, the miscellaneous solids (3) in the carton box are separated from the vertical partition wall (9) of the guide chute (8).
Guided by, and securely enters between the partition bars (6) having a constant pitch formed on the surface of the single-row conveyor (5). After that, the single-row conveyor (5) advances by 3 pitches, and prepares for the next dropping of the carton boxed coarse solids (3) from the stock conveyor (1). The interval of intermittent movement of the stock conveyor (1) and the single-row conveyor (5) as described above may be appropriately set according to the capacity of the incinerator, but in the case of the embodiment, the interval is set to several minutes. There is.

By alternately repeating the forward movement of the stock conveyor (1) and the forward movement of the single-row conveyor (5) in this way, the carton box-containing miscellaneous solids (3) placed on the stock conveyor (1) automatically move to 1 They are arranged in rows and sent to the next process such as an incinerator by a single row conveyor (5).

(Effects of the Invention) As described above, according to the carton box-containing miscellaneous solids conveying device of the present invention, the carton box-containing miscellaneous solids placed on the stock conveyor are automatically incinerated without requiring human labor. Etc. can be sent one by one. Also, since the stock conveyor is wide and the carton box-containing miscellaneous solids can be placed in multiple rows on it, an extremely large number of carton box-containing miscellaneous solids can be stocked and a day's worth of stock can be stocked. After that, fully automatic driving becomes possible after that. Moreover, the transfer from the stock conveyor to the single-row conveyor is surely performed, and there is no fear of failure.

As a result, according to the present invention, the labor of the worker and the risk of radiation exposure can be significantly reduced, so that it contributes to the development of the industry as a carrier device for a miscellaneous solid contained in a carton box that eliminates the conventional problems. The place to do is extremely large.
