Many of these are capable of weighing a few tens of grams with an accuracy of 0.1 grams, but as described above, most of them are discharged from the cylinder, discharge valve, etc. in the weighing hopper. It has a mechanism. Since an electronic balance is adopted for the measuring unit, if a discharge mechanism such as a cylinder or a discharge valve is added, the measured value will vary due to vibration and reaction force during operation of the discharge mechanism. Therefore, in weighing, there is a problem that the processing time becomes long because it is necessary to wait for stabilization of vibrations and the like caused by the discharging mechanism during the previous weighing before performing the next weighing. Further, the conventional weighing device has many components of the discharging mechanism and is expensive.

来る（図６）。The operation when the measuring device is the above means will be described. First, in the means (1), when a signal to start weighing is input to the controller 16, the drive unit 5a of the supply feeder 5 is started and the raw material powder and the like are fed into the weighing hopper 4. The data (weight value) of the balance 3 is transmitted to the controller 16 as a weight signal. When the input amount of the raw material powder or the like reaches the set value, the drive unit 5a of the supply feeder 5 stops, and at the same time, an operation signal is sent to the solenoid valve 14 for operating the cylinder 10.
Then, the drive shaft 10a of the cylinder 10 moves upward, and the leaf spring 9 lifts the shutter 6 to discharge the raw material powder and the like from the weighing hopper 4 (FIG. 4). Next, when the inside of the weighing hopper 4 becomes empty, the solenoid valve 14 is operated and the cylinder 10
The leaf spring 9 fixed to the drive shaft 10a pushes down the shutter 6. In this case, the tip portion (end tool 11) of the leaf spring 9 pushes down the projecting plate 6b from the upper side to move the shutter 6 to the trough 4a.
Push it to the side to close (Fig. 5). According to the means of
When the drive shaft 10a of the cylinder 10 is moved further downward after the shutter 6 is lowered, that is, when the end tool 11 at the tip of the leaf spring 9 is further operated to push down the projecting plate 6b from above, the plate is moved. The leaf spring 9 comes into contact with a stopper 15 provided on the lower side of the intermediate portion of the spring 9, and a pushing force acts on the leaf spring 9, so that the tip end portion (end member 11) of the leaf spring 9 floats and is fixed to the shutter 6. The protruding plate 6b is separated from the protruding plate 6b and is not pushed. In this way, it is possible to prevent impact, reaction force or vibration from acting on the balance 3 through the weighing hopper 4 (FIG. 6).

っている。Between the eave plate 6a and the projecting plate 6b, one end of a leaf spring 9 is arranged with the bolt 7 loosely fitted therein. The other end of the leaf spring 9 is fixed to a drive shaft 10a of a cylinder (either hydraulic or air) 10 installed outside the weighing hopper 4 and can move up and down within a predetermined range. Also, the end piece 1 surrounding the bolt 7 above and below the tip of the leaf spring 9 and penetrating the bolt 7
1 is fixed and attached. However, the end tool 11
Is for evenly pushing the central portions of the eaves plate 6a and the protruding plate 6b up and down as described later. A fluid supply joint 12 and a throttle valve 13 are attached to the cylinder 10, and the cylinder 10 operates a solenoid valve 14 to drive a leaf spring 9 up and down. That is, when the cylinder 10 operates to drive the leaf spring 9 up and down, the leaf spring 9 pushes the eaves plate 6a fixed to the shutter 6 upward by the end tool 11 fixed to the tip end of the leaf spring 9. By pressing the protruding plate 6b downward, the shutter 6 is moved up and down. Therefore, the eaves plate 6a and the protruding plate 6b are two protrusions provided on the side surface of the shutter 6, and the end portion of the leaf spring 9 is arranged between these protrusions. Reference numeral 15 denotes a stopper installed below the intermediate portion of the leaf spring 9, which comes into contact with the leaf spring 9 when the shutter 6 is lowered, as will be described later.

を示している。This weighing device has the above-mentioned structure. Next, the operation at the time of weighing will be described. First, when a signal to start weighing is input to the controller 16, the drive unit 5a of the supply feeder 5 is started and the raw material powder and the like are fed into the weighing hopper 4. The data (weight value) of the balance 3 is transmitted to the controller 16 as a weight signal. When the input amount of the raw material powder or the like reaches the set value, the drive unit 5a of the supply feeder 5
Stop, and at the same time the solenoid valve 14 for operating the air cylinder 10

Moves upward and lifts the shutter 6 by the leaf spring 9 to discharge the raw material powder and the like from the weighing hopper 4. 2 and 3 show a state where the shutter 6 is opened by operating the cylinder 10.

振動が生じるのを防止するように構成されている。Next, when the raw material powder and the like have been discharged from the weighing hopper 4, the solenoid valve 14 is switched by the controller 16 so that the drive shaft 10a of the cylinder 10 is moved downward. Then, the drive shaft 10a moves downward and the leaf spring 9 pushes down the shutter 6. Normally, when the shutter 6 is pushed down in this way, it takes time for the trough portion 4a of the weighing hopper 4 to be impacted by the shutter 10 to generate a reaction force or vibration and to stabilize. However, this weighing device is constructed so as to prevent such impacts and vibrations as will be described below.

離れた状態を示している。In FIG. 4, the solenoid valve 14 is operated by the controller 16, and the leaf spring 9 fixed to the drive shaft 10a of the cylinder 10 raises the shutter 6 to discharge the raw material powder and the like in the weighing hopper 4. It shows the state. In this case, the end tool 11 fixedly provided at the tip of the leaf spring 9 pushes up the eaves plate 6a from the lower side to open the shutter 6. Next, when the inside of the weighing hopper 4 becomes empty, the solenoid valve 14 is operated to operate the cylinder 1
The leaf spring 9 fixed to the drive shaft 10a of 0 pushes down the shutter 6. In this case, the end tool 11 fixedly provided on the tip of the leaf spring 9 pushes down the projecting plate 6b from the upper side to push the shutter 6 toward the trough 4a to close it. FIG. 5 shows a state in which the shutter 6 is just pushed and closed. At this time, the drive shaft 10a of the cylinder 10 is further moved downward, that is, the end tool 11 at the tip of the leaf spring 9 is further operated to push down the protruding plate 6b from the upper side. Then, the leaf spring 9 comes into contact with the stopper 15 provided on the lower side of the middle portion of the leaf spring 9, and a pushing force acts on the leaf spring 9, so that the end tool 11 at the tip of the leaf spring 9 floats and is fixed to the shutter 6. The protruding plate 6b thus separated is no longer pushed. FIG. 6 shows a state in which the tip end portion of the leaf spring 9 is lifted and separated from the projecting plate 6b of the shutter 6.

When the shutter 6 is not completely dropped by the operation of 0 and the shutter 6 does not fall completely, or the shutter 6 is pressed by the spring force of the dropped leaf spring 9, the leaf spring 9 then comes into contact with the stopper 15 and bends back. As can be seen from FIG. 6, when the shutter 6 is closed, the shutter 6 and the leaf spring 9 (the end piece 1
It is separated from 1) and becomes ready for weighing by the balance 3. Further, it is possible to prevent impact, reaction force or vibration from acting on the balance 3 through the weighing hopper 4.
