プルフィーダに関する。[Detailed Description of the Invention] [Industrial field of application] The present invention shifts the sample container to the sample receiver of the electronic balance and vibrates the sample container to transfer the powder sample inside to the sample receiver of the electronic balance. The present invention relates to a sample feeder that can make a small drop income.
従来のサンプルフィーダは、粉体試料を扉（風防）のな
い天秤の試料受器まで延びるシュートを用いて当該試料
受器に導入し秤量をすることができる構成になってい
た。A conventional sample feeder has a structure in which a powder sample can be introduced into a sample receiver of a balance without a door (windshield) and can be weighed using a chute extending to the sample receiver.
このような従来例にあっては、天秤に風防がないため、
粉体試料のフィード時に周囲の風向変化等の影響を直接
受けて安定せず、１mg以下の粉体試料を秤量することが

シュート上に付着するため異種試料を取り扱う場合に
は、前の粉体試料による汚染を防ぐため、シュートを完
全に洗浄しなければ次の粉体試料をフィードできないと
いう課題があった。In such a conventional example, since the balance has no windshield,
Not only is there a problem that when powder samples are fed, they are not directly affected by changes in the wind direction around them and are not stable, making it impossible to weigh powder samples of 1 mg or less, and the powder samples adhere to the chute. Therefore, when handling different kinds of samples, there is a problem that the next powder sample cannot be fed unless the chute is completely washed in order to prevent contamination by the previous powder sample.
本考案は上記の課題を解決するためになされたもので、

進手段とよりなる構成としたものである。That is, the sample feeder of the present invention includes an electromagnetic vibrator 19 having a container mounting portion 10 for holding the sample container 11 with the opening inclined upward as shown in the figure, and the sample container 11 when the door 18 of the electronic balance 14 is opened. When the opening advances to the upper position of the sample receiver 16 of the electronic balance 14, the sample container 11 is vibrated and the sample container 11 is vibrated.
An operating means for vibrating the electromagnetic vibrator 19 to drop the powder sample in 11 into the sample receiver 16 little by little, and a sample container
A means for stopping the vibration of the electromagnetic vibrator 19 when the powder sample in 11 reaches the set weight value, and the electromagnetic vibrator 19
Is constituted by a forward / backward moving means for moving forward and backward when the door 18 is opened and closed, respectively.

にこぼれることはない。Thus, in cooperation with the electronic balance 14 with the door 18, the powder sample in the sample container 11 is gradually dropped into the sample receiver 16 of the electronic balance 14 by the operation of the electromagnetic vibrator 19, and the powder sample in the sample container 11 is Even if the amount is extremely small (about 0.1 mg), the measured value can be accurately measured. Further, since the powder sample is put in the sample container 11 and fed, not only is it not affected by changes in the wind direction of the surroundings during the feeding, but also a separate sample container 11 is used for each powder sample. As a result, contamination between different powder samples can be avoided. Moreover, since the opening of the sample container 11 is inclined upward, the powder sample does not return and spill extra.

状態となる。First, the feeder main body 15 is in the state shown in FIG.
14 is in a state where the door 18 is closed (shown by the solid line in FIG. 2).
A sample container (11) containing a powder sample is inserted between the container mounting spring plates (10) with the opening inclined upward. Electronic balance 14
When a door open signal is input to, the motor operates and the door 18 opens (indicated by the phantom line in FIG. 2). At the same time the feeder body
The container moving motor 1 of 15 is driven to rotate the spur gear 2 attached to the rotating shaft of the motor 1. As a result, the motor 1, the slide metal 5, and the electromagnetic vibrator 19 move (move forward) on the rack gear 3 along the rail 4 in the direction of the end point stop limit switch 13 and stop when they contact the end point stop limit switch 13. When the motor 1 is in contact with the end point stop limit switch 13 and stopped, the opening of the sample container 11 is positioned right above the sample receiver 16 on the weighing pan 17.

で秤量値が読み取られる。When the drop stop signal is input at the stage when the weight of the powder sample in the sample receiver 16 reaches a preset weight, the vibration of the electromagnet 6 stops and the drop of the powder sample stops. At the same time, the motor 1, the slide metal 5, and the electromagnetic vibrator 19 move (reverse) along the rail 4 toward the starting point stop limit switch 12 and stop when they contact the starting point stop limit switch 12. After the sample container 11 which moves backward together with the motor 1, the slide metal 5 and the electromagnetic vibrator 19 is pulled out from the electronic balance 14, the motor is activated by the signal of the closing door and the door 18 is closed ( 2) (shown by the solid line in Fig. 2). Next, when the electronic balance 14 becomes stable, the measured value is read.
