Description

[Detailed Description of the Invention] This invention relates to a collecting device used for collecting articles from the outside while being transported in a closed container.

Generally, when transporting highly dust-producing powders, hazardous substances, dangerous substances, etc., a closed conveyance device is used that conveys the goods along a conveyance path formed by arranging a belt conveyor or chain conveyor inside a closed container. There is. When conveying using such a closed conveyance device, it is necessary to collect the articles currently being conveyed because the articles currently being conveyed cannot be observed from the outside and for component analysis. When performing this collection, the closed conveyance device itself or the hopper etc. that are connected to it in an airtight state are often placed under negative or pressurized conditions to prevent dust generation. It is desirable to collect without affecting the pressure state. Moreover, it is desirable that the collection can be performed from various positions along the conveyance path.

The object of this invention is to provide a collection device that can collect samples from various positions in the conveyance path of a closed container without affecting the pressure state.

Hereinafter, this invention will be explained in detail based on one embodiment shown in the drawings.

In FIG. 1, reference numeral 1 denotes a closed container, and a belt conveyor 3 is arranged horizontally so as to connect an input port (not shown) and a discharge port 2 of the container. The closed container 1 and the belt conveyor 3 constitute a closed conveyance device. Note that an input hopper (not shown), for example, is connected to the input port, and an output hopper (not shown), for example, is connected to the discharge port in an airtight manner.

A communication hole 4 is bored at a position lower than the belt conveyor 3 in the front wall 1a of the closed container 1 forward of the starting end of the belt conveyor 3.

A collection case 6 having a generally L-shaped longitudinal section is attached to the outside of the communication hole 4 via an airtight opening/closing shutter 5 . Therefore, by opening the airtight shutter 5, the collection case 6 communicates with the airtight container 1. A receiving box 8 is detachably attached to the lower end of the vertical portion 7 of the collection case 6.

A container 10 is arranged in the horizontal part 9 of the collection case 6, and this container 10 has an arm 12 led out through the front wall 11 of the collection case 6, and this arm 12 is connected to the operating rod 13. Connected with screws. The arm 12 and the operating rod 13 rotate around the axis of the arm 12 and the operating rod 13 so that the container 10 can move forward and backward between the horizontal portion 9 of the collection case 6 and the belt conveyor 3 of the closed container 1. Possibly, the container 10 is supported on the front wall 11 of the collection case 9 so as to be pivotable in the width direction of the belt conveyor 3, as shown in FIG.

This support structure will be explained with reference to FIG. A circular through hole 15 is bored in the front wall 11, and a cylindrical sleeve 1 is inserted into the through hole 15.
6 is arranged, and a sphere 17 is attached to the outer periphery of the sleeve 16, and this sphere 17 is attached to the through hole 15.
It is in contact with a pedestal 18 provided inside. The arm 12 and the operating rod 13 are inserted into the sleeve 16. Therefore, the container 10 moves forward and backward as described above.
Can rotate and swivel. A flange 19 is formed at the rear end of the sleeve 16.
9 is in contact with protrusions 20, 20 formed on the upper and lower parts of the rear end of the through hole 15, and prevents the container 10 from moving in the vertical direction and allows the sleeve 16 to come out. It prevents Further, a flange 21 is attached to the front end edge of the sleeve 16, and regulating members 22, 22 are provided on the front side of the through hole 15 so as to narrow the through hole 15 from above and below. Sleeve 21 and regulating member 22 Sleeve 1
6 functions as a retainer.

Collecting articles being transported using such a collecting device is performed in the following manner. It is now assumed that the airtight shutter 5 is closed, the container 10 is located in the collection case 9, the operating rod 13 and the arm 12 are separated, and the receiving box 8 is attached to the collection case 9. In this state, the operating rod 13 is screwed to the arm 12, the airtight shutter 5 is opened, and the operating rod 1
Press 3 to push the container 10 into the sealed container 1.
3, the container 10 is pushed as it is to the lower front of the conveyor 3, and when collecting the article at the position shown as 10a or 10b in FIG. After rotating the rod 13 in the direction of arrow 23a or 23b, the container 10 is pushed to the lower front of the conveyor 3. After storing the article in the container 10, the operation rod 13
, return the container 10 to the collection case 9, and close the opening/closing shutter 5. Then, by rotating the operating rod 13, the container 10 is rotated and the articles therein are transferred to the receiving box 8. Thereafter, the collecting of the articles is completed by removing the receiving box 8 from the collecting case.

The collection device configured as described above includes a collection case 6 that communicates with the closed container 1, and an airtight opening/closing shutter 5 between the closed container 1 and the collection case 6.
Since the container 10 is provided inside the collection case 6 so as to be movable between the closed container 1 and the collection case 6, the articles inside the closed container 1 can be collected without changing the pressure state inside the closed container 1. Can be collected. moreover,
Since the container 10 can be moved in the width direction of the belt conveyor 3 within the closed container 1, articles at various transport positions can be collected. Moreover, after collecting the sample in the container 10, return the container 10 to the collection case 6,
When the operating rod 13 is rotated, the collected sample is transferred to the receiving box 8, and by removing this receiving box 8 from the collection case 6, the collected sample can be easily taken out. Further, although the operating rod 13 and the arm 12 are connected by screws, various methods can be used to connect the two.
