DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for weighing various kinds of substances having different set volumes within a measuring range of each substance.

[0002]

2. Description of the Related Art In the pharmaceutical, food and other industrial fields,
Substances with different content components such as powders, liquids, etc.
Mixing is performed within the measurement and measurement range of each substance. Conventionally, when mixing various kinds of substances described above within the measurement and measurement range of each substance, different measurement containers are required depending on the measurement and measurement range.

[0003]

Therefore, in order to move each weighing container, moving devices as many as the number of weighing containers are required. For example, 30 types of substances can be measured in three ranges (100-1000 g, 1 kg-10 kg, 1 kg).
Weighing between 0 kg and 100 kg), requires three measuring containers per measuring weighing range, in this case,
Three moving devices were required.

When three weighing containers are moved by an elevator or the like, if they are moved separately, it takes three times as long to transport. If three weighing containers are moved at the same time to reduce the time, three weighing containers are required. A device for integrating the measuring containers into a single unit was required. Further, after the movement, a device for separating the individual measuring containers combined into one unit for each measuring container is also required. Therefore, the apparatus for weighing becomes large-scale, and the work of processing each weighing container after weighing is also inefficient.

Is a plurality of hoppers that respectively accommodate the hoppers.

The moving table 3 on which the large weighing container 1 and the small weighing container 2 are placed can be moved on the moving device 13 in a fixed direction, but is stopped in a predetermined position by a stopper 14 in a stepwise manner. In this stop position, there is a large measuring device 8 below the large measuring container 1 and a small measuring device 9 below the stop position of the small measuring container 2. A plurality of hopper groups 4 to 7 are located above the stop position of the large weighing container 1, and a plurality of hopper groups 17 to 2 are located above the stop position of the small weighing container 2.
0 is located.

The moving table 3 on which the large measuring container 1 and the small measuring container 2 are placed moves in the direction of arrow A in FIG. 1, and the moving table 3 is at a predetermined position, that is, the large measuring container 1 is When the cylinder 14 reaches the lower surface of the object to be measured, the stopper 14 which can be moved up and down by the crank mechanism by the cylinder 15 projects above the base 12 and the moving device 13 to stop the moving table 3. In this state, when the large weighing device 8 is lifted by the elevating device 10, the support 16 protruding from the upper portion of the large weighing device 8 passes through the base 12 and the moving device 13 and protrudes above the moving table 3 to be weighed large. Since the container 1 is lifted and the large measuring container 1 is supported by the large measuring device 8, the large measuring container 8 receives the load of the large measuring container 1. In addition, the moving base 3 and the base 1
2, a gap is formed for the support 16 to protrude upward.

With the large weighing device 8 supporting the large weighing container 1, for example, an object to be measured such as a powdery or particulate substance or a liquid within a predetermined measurement weighing range in the order of the first hopper 4 to the fourth hopper 7 is large. When put into the measuring container 1, the individual hoppers 4,
The large measuring device 8 measures and weighs the input amounts of 5, 6, and 7,
When the predetermined weighing value is reached, the charging of the measured object from each of the hoppers 4, 5, 6, and 7 is completed. Thereafter, when the large weighing device 8 is lowered to a predetermined position by the elevating device 10, the large weighing container 1 is fixed on the moving table 3.

In addition, the loading of the object to be measured from each of the hopper groups 4 to 7 is started by a command from the control device when the preparation for weighing is completed. The end of the charging is controlled by the measured value data from the large measuring device 8.

For example, the first hopper 4 is 15 kg,
When the hopper 5 is set to supply 18 kg, the third hopper 6 is set to 14 kg, and the fourth hopper 7 is set to input the object to be measured having different content components, the larger than the hopper 4 by a command from the control device. The charging is started into the weighing container 1 and the control device is controlled by the hopper 4 based on the measured value data from the large weighing device 8 so that the charged amount becomes the same as the set value.
Stop feeding from. In this way, the hopper 5,
Objects to be measured are sequentially put on the large weighing container 1 from 6 and 7. Incidentally, as the hoppers 4, 5, 6 and 7, conventionally known hoppers can be used.

As described above, when the objects to be measured having the set values are inputted from the hopper groups 4 to 7 into the large weighing container 1, the movable table 3 is automatically moved in the direction of the arrow B. FIG.
As shown in the figure, the small weighing container 2 has a plurality of hopper groups 17 to
When reaching the lower surface of the workpiece input port 20, the stopper 14 having the same mechanism as the above-mentioned structure projects and stops the movable base 3.
Next, when the small weighing device 9 is lifted by the lifting / lowering device 11 and the support 16 lifts the small weighing container 2 above the moving table 3 and is in a measurable state, the hoppers 17, 18, 19, and 20 are removed The measured object of each set value is a small weighing container 2
It is thrown in in order. These working procedures are exactly the same as those of the large weighing container 1. However, there is a difference that the input amount from each of the hopper groups 17 to 20 is small. An object to be measured having a set value is introduced into the small weighing container 2, and when the introduction is completed, the object is lowered by the elevating device 11, and the small weighing container 2 is fixed on the movable table 3.

Next, the moving table 3 is moved in the direction of arrow C. When reaching the predetermined position, the large weighing container 1 and the small weighing container 2 are lowered from the moving table 3, and the object to be measured contained in the large weighing container 1 and the small weighing container 2 is put into another large container. Mixed. Incidentally, in the drawing, the hopper groups 4 to
7 and the hopper groups 17 to 20 have the same size, but since the amount of the hoppers 17, 18, 19, and 20 charged into the small weighing container 2 is small, the hoppers 17, 1
8, 19 and 20 may be smaller than hoppers 4, 5, 6 and 7. In addition, hopper group 4
Although the number of hopper groups 17 to 20 and the like is four, the number can be changed as required. Further, three or more weighing containers can be used.

In the above-described embodiment, a case has been described in which the object to be measured is charged into the large weighing container 1 and then the object to be measured is charged into the small weighing container 2. However, the order may be reversed. .

FIG. 3 and FIG. 4 show a second embodiment of the present invention, in which the same parts as those in the above-mentioned embodiment use the same reference numerals.
The present embodiment is characterized in that a predetermined amount of an object to be measured is put into the large measuring container 1 and the small measuring container 2 from a group of hoppers. For this reason, in the present embodiment, the large scale 8
The small weighing instrument 9 and the small weighing instrument 9 are placed and fixed on a single carriage 21, and the carriage 21 is movable in the same direction as the movable platform 3. In addition, stoppers 14 are provided on the base 12 at two positions along the moving direction of the moving base 3.

In FIG. 3, the moving table 3 is sent on the moving device 13 from the direction of the arrow D, and the small weighing container 2 is
When reaching the lower surfaces of the non-measurement object inlets 5, 6, and 7, the first stopper 14a projects above the moving device 13 and stops the moving table 3. When the carriage 21 moves in conjunction with the movement of the movable base 3 or separately from the movement of the movable base 3 and the carriage 21 is positioned below the stopped movable base 3, the lifting / lowering device 11 is operated, and the small scale 9 is raised, The support 16 lifts the small weighing container 2 above the moving table 3. Objects to be measured having a set value are sequentially put into the small weighing container 2 from the hoppers 4, 5, 6, and 7 controlled by the weighing value data of the small weighing device 9, and when the total amount reaches a predetermined amount, the charging is stopped. Then, the small weighing container 2 is lowered by the elevating device 11, and the small weighing container 2 is

When the charging into the small measuring container 2 is completed, the stopper 14a is retracted below the base 12, and the movable base 3 is moved in the direction of the arrow E. As shown in FIG. 4, when the large weighing container 1 reaches below the measured object inlet of each of the hopper groups 4 to 7, the second stopper 14 b projects above the moving device 13 to stop the moving table 3. At this time, the bogie 21 also moves in the same direction and the same distance as the movable base 3, so that the vertical positional relationship between the large measuring container 1 and the large measuring device 8 and the small measuring container 2 and the small measuring device 9 may not be changed. Absent.

In this state, the lifting / lowering device 10 raises the large weighing device 8 and the support 16 lifts the large weighing container 1 above the moving table 3. Is charged into the large weighing container 1 as in the case of the small weighing container 2. When the charging of the predetermined amount of the object to be measured is completed, the large weighing device 8 descends and the large weighing container 1
Is placed on the moving table 3.

Thereafter, the stopper 14b is retracted downward, and the moving table 3 advances in the direction of the arrow F. When reaching the predetermined positions, the large measuring container 1 and the small measuring container 2 are lowered from the moving table 3, and the large measuring container 1 and The contents accommodated in the small measuring container 2 are put in another large container and mixed.

The carriage 21 returns to the predetermined position and is ready for the next operation. In addition, although the case where the carriage 21 moves in the same direction as the moving carriage 3 has been described, if the stopper 1
When the presence of 4a hinders the movement, the carriage 21 on which the large weighing device 8 and the small weighing device 9 are placed can be moved in a direction (a depth direction in the drawing) orthogonal to the moving direction of the movable platform 3. Is also good. If the positional relationship between the large weighing container 1 and the large weighing device 8 and between the small weighing container 2 and the small weighing device 9 is automatically selected, the operation can be easily performed.

A large weighing device 8 for weighing the large weighing container 1 and a device 10 for raising and lowering the large weighing container 1 are installed below the rails 22.

The operation of putting the object to be measured into the large weighing container 1 from each of the hoppers 4, 5, 6, and 7 is the same as that in each of the above embodiments, and the detailed description is omitted. Large measuring container 1
When the loading of the trolley 22 is completed, the carriage 22 advances in the direction of the arrow G by the driving device 24, the object to be measured is loaded into the small weighing container 2 from the hopper group of small loading, and the set value is measured by the small weighing device 9 (not shown). This is the same as in the above embodiments.

The driving of the driving device 24 is also performed by the above-mentioned control device. The carriage 23 may be stopped at a predetermined position by a stopper. Alternatively, the drive unit 24 may be stopped by an appropriate device or mechanism capable of detecting the position of the carriage 23 to perform positioning.
