A lifting cylinder (33) is arranged. An elevating cylinder (26) for elevating the electric furnace (17) is provided directly below the vibrating piece (3) below the moving carriage (25) on the fixed base (21).

By the way, the expansion / contraction operation of the rod of the horizontal cylinder (24) is performed by the limit switch (not shown) incorporated therein and the photoelectric switch (not shown) arranged outside, as in the above embodiment. It is controlled by double detection with.

The lifting cylinder (26) and the liquid container lifting cylinder (33) have the vibrating piece (3) inside the sample container (2) at the uppermost position of the stroke end of the rod, as in the lifting cylinder in the first embodiment. It is controlled so as to be immersed in the fluid to be measured (1), the standard viscosity liquid in the liquid container (18) or the cleaning liquid (19). The rotation table (31) controls the rotation of the motor (34) so that it can be intermittently stopped at 60-degree intervals by a photoelectric switch (not shown).

Further, at one end on the left side in the figure of the fixed base (21), a hopper lifting cylinder (4

6b) and is lifted upward, and at the stroke end of the rod (33a), this rod (33a)
Extension is stopped. At this stop position, the vibrating element (3) is moved to the standard viscosity liquid or the cleaning liquid (1) in the liquid container (18).
9) Be sure to be immersed in.

The method of immersing the vibrating piece (3) in the standard viscosity liquid or the cleaning liquid (19) is the same as that described in the first embodiment, ie, the standard viscosity liquid A → the cleaning liquid I → the cleaning liquid II → the standard viscosity liquid B → the cleaning liquid I. → The cleaning liquid II → the standard viscosity liquid C → ..., but if the liquid containers (18) containing these liquids are sequentially placed in advance on the rotary table (31), the liquid containers (18 )

Then, the material supply hopper (45) is driven by the tilting motor (44).
Is tilted to feed the raw material powder into the sample container (2) through the raw material supply chute (45a) without being scattered into the electric furnace (17). The liquid level in 1) can be easily adjusted.

The amount of the raw material powder to be replenished is calculated based on the composition of the raw material powder by calculating the volume at the time of melting required for an appropriate liquid level, and the difference from the melting volume of the raw material powder supplied in advance. Ask.

As described above, in the vibration type viscometer according to the second embodiment, the vibrating piece (3) is automatically immersed in the fluid to be measured (1), the standard viscosity liquid or the cleaning liquid (19). In addition to that, even if the fluid to be measured (1) is at a high temperature, the work of adjusting the liquid level can be easily performed, so that the viscosity of the fluid to be measured (1) can be measured in an extremely short time. This can be done, and furthermore, the individual error between the measurers can be eliminated.

In the above, an example in which the vibrating reed (3) is immersed in the fluid to be measured (1), the standard viscosity liquid or the cleaning liquid (19) and raised by means for moving up and down each of the containers in which they have been described has been described. Conversely, even if the vibration type viscometer main body (m) itself is lowered, the same effects as those of the respective embodiments described above can be obtained. Further, the lower structures of these examples can be applied to the conventional vibrating viscometer disclosed in JP-A-59-15837.

The above-mentioned vibration type viscometer is only a specific example of the present invention, and therefore, the scope of the technical idea of the present invention is not limited by these examples, and the scope of the technical idea is not deviated. Design changes within the range are free.

Further, according to the vibrating viscometer according to the fourth aspect of the present invention, in addition to the above effects, the raw material powder is supplied to the sample container by the raw material supply hopper to uniformly maintain the liquid level of the fluid to be measured. As a result, there is no variation in the immersion addition of the vibrating piece, and it becomes possible to reliably reduce individual differences such as the measurer, and the work efficiency of viscosity measurement using this type of viscous viscometer can be reduced. And the accuracy of measurement are greatly improved.
