(Field of Industrial Application) The present invention relates to an automatic powder weighing device that can accurately weigh a wide variety of powder samples without contaminating each other. (Prior Art) In recent years, in order to mix inorganic substances such as ceramics and cement to produce new mixtures, there has been a need to automatically and accurately weigh powder samples on the order of milligrams. Conventionally, as a device capable of accurately weighing a powder sample for this purpose, a device is equipped with a vibrating feeder at the outlet of a powder sample hopper and automatically feeds the powder sample into a predetermined container on an electronic balance. It has been known. (Problems to be solved by the invention) However, the above-mentioned powder sample weighing device
All of them were constructed for the purpose of weighing one type of powder sample. Therefore, in order to weigh powder samples of other types, you must replace the hopper of the powder sample and also replace or clean the vibration feeder.
It was necessary to make sure that the powder sample that had been weighed just before was not mixed in, which had the disadvantage of being time-consuming. Furthermore, even if such measures are taken to prevent contamination with the powder used immediately before, contamination cannot be completely eliminated, and weighing accuracy is not sufficient, and cross-contamination of samples is not allowed. There was a drawback that it could not be applied to weighing powder. SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned problems and provide an automatic powder weighing device that can accurately and automatically weigh a wide variety of samples. (Means for Solving the Problems) The automatic powder weighing device of the present invention includes a weighing device comprising an electronic balance for measuring the weight of powder, and a weighed powder sample held in a weighing cup tray. A weighing cup supplying device consisting of a weighing cup for storage, a weighing cup transfer device for transferring the weighing cup from the weighing cup tray to the weighing device and returning it to the weighing cup tray after completion of weighing, and a weighing cup held in the sample container tray, A sample container with a feeder for storing a powder sample to be weighed, which also serves as a vibrating feeder and has a removable lid, and a vibrator unit for feeding the sample in the sample container with a feeder into a weighing cup on a weighing device. and a sample container transfer device that selects a desired container from sample containers with feeders held in a sample container tray and transfers the selected container to the vibrator unit of the sample container tray. and,
The present invention is characterized by comprising a control device that controls the operations of the weighing device, the weighing cup supply device, and the sample supply device and performs predetermined calculations. The term "powder" used in the present invention is a concept that includes fine powder, coarse powder, and granular powder. (Function) In the above-described configuration, a plurality of sample containers each containing a variety of powder samples are held, and a predetermined powder sample is exchanged by automatically exchanging the sample containers. A wide variety of powder samples can be weighed automatically. In addition, since we use a sample container with a feeder that has a lid with an integrated vibrating feeder as the lid of the sample container, even if you change the product type, you can prevent the contamination of the sample from the previous sample without having to change or clean the feeder. can. Note that it is preferable to provide a blade of a predetermined shape in the sample container with a feeder, since powder samples that tend to agglomerate due to vibration can be suitably fed to the feeder, thereby preventing deterioration of weighing accuracy due to agglomerated particles. Further, it is preferable that the sample supply device has a hopper and a vibration feeder for supplying powdered additives, since the additives that need to be repeatedly supplied can be suitably mixed into the sample. . Furthermore, when the sample container with feeder is vibrated by the vibrator unit to supply the sample into the weighing cup for weighing, the voltage applied to the vibrator unit is controlled by the control device while detecting the amount of powder supplied to the weighing cup. It is preferable to change the weight in multiple stages, increase or decrease the vibration of the vibrator, and converge the vibration to achieve the target weight, since more accurate weighing can be achieved. (Example) FIG. 1 and FIG. 2 are a plan view and a front view showing an example of an automatic powder weighing device of the present invention. In this embodiment, first, a plurality of weighing cups 1, each containing 10 weighing cups 1 containing nothing therein, are held in the weighing cup trays 2-1 and 2-2. The weighing cup trays 2-1 and 2-2 are configured so that they can be alternately positioned to be conveyed by a tray slide mechanism 3 to the cup conveying position, that is, the position of tray 2-2 in the figure. The weighing cups 1 in the weighing cup tray 2-1 or 2-2 at the cup transporting position are sequentially transported by the weighing cup transfer device 4 onto an electronic balance 5 as a weighing device. The weighing cup transfer device 4 includes a container gripping mechanism 6 that clamps the weighing cup 1, and a container lifting/lowering transfer mechanism 7 that transports the weighing cup 1 onto the electronic balance 5 while holding the weighing cup 1. Also,
As the electronic balance 5, any commercially available one can be selected depending on the weighing accuracy, and in this embodiment, an electronic balance with a maximum weighing value of 200 g and a reading limit of 0.1 mg is used. A powder sample in the sample container 8 with a feeder to be weighed is loaded into the weighing cup 1 on the electronic balance 5 by a sample supply device 11 consisting of a sample container 8 with a feeder, a sample loading device 9, and a sample container transfer device 10. By supplying small amounts of powder into the weighing cup 1 and measuring the weight at regular intervals, the amount of powder supplied is detected, and the target weight value is achieved by increasing or decreasing the vibration of the vibrator unit. That is, ten sample containers 8 with feeders each containing a different sample are held in each of the sample container trays 12-1 and 12-2. Each sample container tray 12
-1, 12-2 are sample container tray slide mechanism 1
3, it can be transported to the position of the sample container transfer device 10, and furthermore, it is configured so that it can be transported in a direction perpendicular to the transport direction at that position. The sample container transfer device 10 is moved by the sample container tray slide mechanism 13.
The sample container 8 with a feeder that accommodates the sample to be weighed next reaches the position indicated by the imaginary line in FIG. The sample container is transported and fixed on the unit 15 by the drive of the sample container transfer device 10. If the sample container 8 that has already finished weighing the sample is clamped by the container clamp mechanism 14, first, the predetermined position in the sample container tray 12-1 or 12-2 to which the sample container 8 should be returned is set for sample container transfer. After driving the tray slide mechanism 13 to the position of the device 10, the sample container transfer device 10 is driven at that position to return the sample container 8 to a predetermined position, and then the above-described transfer and fixing operation of the sample container 8 is performed. are doing. The sample loading device 9, which has fixed the sample container 8 to be weighed by the clamp mechanism 14, returns to the position indicated by the solid line in the figure, and transfers the sample in the sample container 8 into the weighing cup 1 on the electronic balance 5 by the vibration of the vibrator unit 15. The target weight value is determined by supplying the weight. At this time, the vibration of the vibrator unit 15 can be kept constant up to the target weight, but the weight of the powder supplied to the weighing cup is measured at regular intervals and the voltage applied to the vibrating feeder is increased or decreased. This is preferable because accurate weighing can be achieved by converging the strength of the vibration that controls the amount of body supplied to the weighing cup so as to achieve the target weight. In this embodiment, powder hoppers 16-1, 16-2 and electromagnetic feeder units 17-1, 17-2 are movably provided in the sample supply device 11 described above to the positions shown by the imaginary lines in FIG. -1 or 16-2 is configured to be able to be weighed by supplying the additive powder in weighing cup 1 together with the sample. Powder to be supplied in large quantities is preferably supplied by these devices. The weighing cup 1 in which a predetermined sample and additive powder are weighed and housed is the same as the above-mentioned weighing cup 1.
In the reverse process of transferring the cup onto the electronic balance 5, the weighing cup transfer device 4 returns it to a predetermined position on the weighing cup tray 2-1 or 2-2. The operations of these devices described above are all controlled by the control device 18. As the control device 18,
I am using a regular computer. FIGS. 3a and 3b are cross-sectional views showing an example of a container with a feeder 8 used in the present invention. The sample container 8 shown in FIG. 3a is composed of a container body 21 and a lid 23 having a feeder 22. As shown in FIG. As the container body 21, a commercially available glass weighing bottle is used. The feeder 22 is formed integrally with the lid 23 via the powder supply port 24, and is connected to the container body 21.
A lid 23 is attached to the sample container 8 with a feeder. When the sample container 8 with a feeder is vibrated by the vibrator unit 15 in the state shown in FIG. Supplied within 1. The sample container 8 with feeder shown in FIG. 3b shows another example,
The difference from the example shown in FIG. 3a is that a blade 25 is provided inside the container body 21. This blade 25 has the role of loosening the aggregated powder by vibration, and in this embodiment, more accurate weighing of the sample can be achieved. The operation of the automatic powder weighing device of the present invention described above is as follows. First, weighing cup tray 2-
Place an empty weighing cup 1 at 1, 2-2. Next, the sample containers 8 with feeders each containing a different sample are placed at predetermined positions in the sample container trays 12-1, 12-2, and the positions, types, and order of weighing are input into the control device 18. . Here, the weighing cup transfer device 4 is driven to transport the weighing cup 1 in the weighing cup tray 2-1 or 2-2 onto the electronic balance 5. Next, sample container tray 12-1
Alternatively, a predetermined feeder-equipped container 8 in 12-2 is attached by the clamp mechanism 14 to the tip of the sample input device 9 tilted by the sample container transfer device 10.
After the sample input device 9 returns to its original position, the vibrator unit 15 starts vibrating to supply a predetermined amount of sample into the weighing cup 1. At this time, it is necessary

きる。[Table] As can be seen from the results in Table 1, the automatic weighing device of the present invention allows accurate weighing regardless of the type of powder. The present invention is not limited only to the embodiments described above, and numerous modifications and changes are possible. For example, in the above example, each sample container was filled with different powders, but if you want to weigh a large amount of a certain kind of sample, you can also put the same sample in a sample container and perform the same operation. . Furthermore, it is clear that the type of sample container is not limited to commercially available glass weighing bottles, and the number of weighing cups, sample containers, trays, etc. is not limited only to the embodiments described above. (Effects of the Invention) As is clear from the above detailed explanation, the automatic powder weighing device of the present invention has a plurality of sample containers each storing a variety of powder samples, and Since a predetermined powder sample is replaced by automatically replacing the sample container, a wide variety of powder samples can be automatically weighed.
In addition, since we use a sample container with a feeder that has a lid with an integrated vibrating feeder as the lid of the sample container, even if you change the product type, you can prevent the contamination of the sample from the previous sample without having to change or clean the feeder. can.
