Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powder sampler, and more particularly to a powder sampler for a robot.

<Description of Prior Art> Conventionally, methods for collecting powder samples using robots or manipulators include (1) placing a sampling container on a balance, and dropping the sample into the container in small amounts using the vibrations of a vibrator; Collection method (2) A method is known in which a fixed amount of sample is collected using a volumetric filling device.

However, the former method is not suitable for continuously collecting samples, and when handling multiple types of samples, the sample container must be cleaned or replaced each time the type of sample changes to prevent contamination. Must be. The latter method is suitable for separating a fixed amount of sample, but is not suitable for separating an arbitrary amount of sample.

The inventors of the present invention have completed the present invention after intensive study on a powder sampler for a robot that can continuously and arbitrarily collect powder samples.

An embodiment of the present invention is shown in FIG. 1 and will be described in more detail.

A collar 3 is provided at the upper part of the outer cylinder 1, and the size of the collar 3 is preferably larger than the opening of the test tube when a test tube is used as the separation container. The inner tube 2 is longer than the outer tube 1 and is inserted into the outer tube. The ring 6 is attached to a groove provided on the outer periphery of the lower part of the inner cylinder, supports the lower part of the inner cylinder in the lower part of the outer cylinder, prevents the inner cylinder from shifting, and maintains airtightness within the instrument. The ring 5 is attached to the inner cylinder 2 above the upper end of the outer cylinder. The ring 5 is the support tube 4
This also prevents the inner cylinder from shifting and maintains airtightness within the instrument. The numbers of the rings 5 and 6 are not particularly limited and may be appropriately determined within a range that allows the inner cylinder to move smoothly within the outer cylinder and maintains sufficient airtightness. A circular filter 7 is fitted into the lower end of the inner cylinder 2. The filter 7 can be replaced every time the sample particles change, and a filter having a pore size smaller than the particle size of the sample may be appropriately selected and used. The inner tube is provided with a collar 8 above a portion of the same length as the outer tube, and the collar 8 serves to support the instrument when the instrument is stored in a rack or the like. In addition, at that time, the size of the main brim 8 is larger than the size of brim 3.
It is more convenient to increase the size of . There is no particular restriction on the shape of the brim 3 and 8, but a circular shape is generally preferred. The support cylinder 4 is fitted into both cylinders when the inner cylinder 2 is inserted into the outer cylinder 1, and simultaneously supports the upper part of the outer cylinder above the collar 3 and the lower part of the inner cylinder below the collar 8. At this time, the lower part of the support cylinder is fitted into the outer cylinder 1, and the inner diameter of the upper part is larger than the outer diameter of the inner cylinder and smaller than the outer diameter of the ring 5. A connecting cylinder 9 is fitted into the upper end of the inner cylinder 2. A suction/exhaust nozzle is attached to the connecting tube, and by applying suction or pressurization to the inside of this instrument, a powder sample can be collected or discharged by suction.
Furthermore, if a chamfer is provided at the upper end of the connecting tube, the nozzle can be more smoothly attached to the connecting tube.

Next, an outline of the operation method using a robot or the like will be explained.

1. This instrument is first set easily with the inner cylinder pulled up.

2 The robot fits the suction nozzle into the connecting tube 9,
After placing the lower end of the outer cylinder on the capacity setting table, push down the collar 8 to set the lower end of the inner cylinder to an arbitrary position. At this time, the height of the capacity setting table from the base surface, data on the physical properties of the sample, etc. are set in the computer, and the push-down position of the robot is commanded by giving the required weight for collection.

3. Next, the robot inserts this instrument into the sample container, applies suction, and collects the sample into the space at the lower end of the outer cylinder by suction.

4. After collecting the sample, pull up this device and scrape the sample at the bottom of the outer cylinder with the edge of the sample container to stabilize the amount collected, then move it and insert it into the preparative container. The inner tube is pushed up and dropped into a container for sample collection, and finally compressed air is added to completely eject the tube. At this time, the collar 3 serves as a lid for the sample container to prevent the sample from scattering.

5. After collecting the sample, use a balance to measure the weight of the collected sample and measure the accurate weight to further improve accuracy.

<Effects of the invention> By using the powder sampler of the present invention, powder samples can be collected continuously and in arbitrary amounts. It is an excellent vessel.
