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, 1-10 Kg, 10-
In the case of weighing at 100 kg), three measuring containers were required for each measuring weighing range, in this case, and thus 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.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a box-shaped movable cart, and a plurality of weighing containers having different capacities are placed on a support plate 1a of the movable cart 1. The one shown is capacity 10
0Kg large measuring container 1 and 1000g small measuring container 2
Are shown.

A large weighing device 4 and a small weighing device 5 for weighing the large weighing container 2 and the small weighing container 3, respectively, are installed below the support plate 1a in the movable carriage 1. The large weighing device 4 is located below the large weighing container 2 and the small weighing device 5 is located below the small weighing container 3, and both the weighing devices 4, 5 are moved by lifting devices 6, 7 such as cylinders. Is held. Reference numerals 8, 9 and 10, 11... N denote a plurality of hopper groups each containing a substance (measurement object) having a different content component, and are arranged in parallel above the moving trolley 1 along the transfer direction. It is arranged.

The mobile trolley 1 can move in a certain direction, and the mobile trolley 1 sent from the left side of the drawing now.
When the upper large weighing container 2 reaches the lower surface of the workpiece input port of the first hopper group 8, 9, the movable carriage 1 is stopped by a suitable stopper (not shown) or other stopping machine, and the stopped state is maintained. Is done.

When the movable carriage 1 stops, the lifting device 6 operates to move the large measuring device 4 upward, and the support 12 projecting above the large measuring device 4 is moved from the through hole 13 formed in the support plate 1a. The large weighing container 2 protrudes upward and is lifted above the movable trolley 1. Accordingly, the load of the large measuring container 2 is applied to the large measuring device 4. In this state, in the large measuring container 2,
Substances (objects to be measured) having different content components are sequentially supplied from the hoppers 8 and 9 by a set amount.

The movement of the mobile trolley 1, the stop at a predetermined position, the elevation of the large weighing device 4 by the lifting / lowering device 6, and the like are all set to operate automatically and in conjunction with each other by electrical control by a control device (not shown). ing. In particular, the input of the object to be measured from the hoppers 8 and 9 is started by a command from the control device when the preparation for weighing is completed. Further, the end of the charging is controlled by the measured value data from the large measuring device 4.

The amount of the object to be measured from each of the hoppers 8 and 9 is set in advance.
When the input amount of Kg and the hopper 9 are set to the input amount of 36 kg, when the set amount is input from the hopper 8, the control device controls the input from the hopper 8 based on the measured value data from the large scale 4. Stop. Next, when 36 kg of the substance is charged from the hopper 9, the measured value data from the large measuring device 4 is sent to the control device, and the charging is stopped. Incidentally, a conventionally known hopper can be used.

When the loading of the objects to be measured from the hoppers 8 and 9 is completed, the large weighing device 4 is lowered to a predetermined position by the lifting device 6, and the large weighing container 2 is placed on the support plate 1a.
Next, the mobile trolley 1 is transferred in the direction of arrow A, and stops when the large weighing container 2 reaches below the next hopper group 10, 11, and the same operation as described above is performed. In this way, when different substances are charged into the large weighing container 2 by a required amount from a plurality of hoppers, a small amount of the different substances are charged into the small weighing container 3 from the plurality of hoppers in the next stage. The charging operation is exactly the same as that of the large weighing container 2.

In the above description, first, in the large measuring container 2,
From a plurality of hoppers installed in the transfer direction of the mobile trolley 1,
Although the case where the measuring object is charged into the small measuring container 3 after the setting amount of the measuring object of each hopper is charged has been described,
It is not limited to this. That is, the hoppers 8 and 9
, A set amount of the substance is put into the small weighing container 3, the movable trolley 1 is slightly moved, and the set amount is put into the large weighing container 2 from the hoppers 8 and 9.
The objects to be measured may be input in the order of the small weighing container 3 → the large weighing container 2 at 0 and 11, and this may be repeatedly performed by each hopper group in the transfer direction of the movable carriage 1. In this case,
It is necessary to switch the input amount of each hopper between large and small.

In the above description, in order to protect the measuring devices 4 and 5, the large measuring device 4 and the small measuring device 5 have the large measuring container 2 and the small measuring device 5 during non-weighing and while the movable carriage 1 is moving. The load of the container 3 is not applied, and the large weighing container 2 and the small weighing container 3 are lifted by the lifting devices 6 and 7 only at the time of weighing. However, if the measuring device that the load of the large measuring container 2 and the small measuring container 3 can always apply to the large measuring device 4 and the small measuring device 5 is used, the lifting devices 6 and 7 are unnecessary. In this case, the support plate 1a of the movable trolley 1 is unnecessary, and the large weighing container 2 is attached to the large weighing device 4 and the small weighing container 3
May be directly set on the small scale 5.

[0017]

According to the present invention described above, a plurality of weighing containers having different capacities are placed on one movable trolley, and each weighing container can be weighed by a weighing device installed on the trolley. Therefore, by placing the weighing container below a plurality of hopper groups arranged above the moving direction of the movable trolley, the hoppers continuously feed substances having different content components and different input amounts from each hopper. be able to. Moreover,
At the time of material introduction, each measuring container is weighed by a measuring device, and the amount of input from the hopper is detected by the measuring device, and the measured value data is sent to the control device, so that weighing can be performed with high precision. It is possible to improve work efficiency. Since multiple weighing containers and weighing instruments are mounted on a single moving trolley, it is possible to select not only movement in a straight line but also movement in a curved direction depending on the arrangement of the hopper group. The moving range is extremely wide. If each weighing container can be directly placed on the weighing device on the movable trolley, the lifting device is not required, and the entire device can be reduced in size.
