A distribution mechanism CD+ that can be stopped automatically is provided, and the linked switching drive mechanism ta+ and the distribution mechanism (2) are connected to each load support device (4), prisoner storage device fl), is)
In a device configured to be used cyclically for one pair of K, it is detected that the displacement amount due to storage of the object to be weighed in each of the load supporting devices shown in (A) above has become equal to or greater than the set value. Based on the detection results, a load supporting device (4) is provided with a detection mechanism (Ka) that performs a detection operation preferentially among these detection mechanisms rxm)t(Ka). ) is linked to the balancing device @1.
11flEl linkage switching drive mechanism (control mechanism (2) for automatically lowering the Q is provided, and the balancing device (
All the balancing devices (B) are provided with one mechanism (rotation) that detects when the load supporting device (4) linked to B3 has reached the hair position at the time of supplying a predetermined metered amount. Based on the detection results! IIE! Linkage switching drive mechanism (Q
A control mechanism (8) is provided for automatically transitioning to the next operation in its cycle operation.

The linkage switching drive mechanism (Q is, for example, as shown in the figure, each load support device (A), the platform i31 in fAl, 1
With respect to the standoff frames (4) and (4) from 3+, cams that are out of phase with each other support the other standoff frames (4) from the ground when separated from the seven standoff frames (4). (11, (6)
A rotating shaft (6) with a rotating shaft (6) attached to the shaft end is pivotally supported on a fixed frame (8), and a balancing device (B) K is provided. A locking member (11), (+t) is attached to each stand frame t4t, +41 to be selectively suspended and locked to a weighted bar tto installed horizontally at the free end of the rod (9). The vertical frame (4) on the lowered side separated from the cam (6) has its locking member (11) locked to the weight bar 11 and is linked to the balancing device (Ill). The lifting frame (4) on the side supported and lifted by the cam (!i) has its locking member (ll) floating from the weight bar ■ and the balancing device (8)
It is constructed so that it is insulated from the

It is desirable that the driving machine (Ma) and the rotating shaft (@) be provided with a round locking device to check the rotation of the other side thereof.
As the drive mt7), there are a geared motor, a V cylinder, etc.

The said distribution mechanism (2) is, for example, as shown in the figure, with a single continuous supply path (in front of each storage tool (1)).

The device is equipped with a diverter atr that guides the distribution toward the mouth) and a ninth driving machine that moves the diverter atr to change the distribution ratio. Storage equipment 1
When there are two flow dividers, a simple chevron-shaped one as shown in the drawing can be used as the nine flow dividers.

In addition to the V-cylinder, the driving machine a may be a nine-motor with a gear that engages the rack.
If there are more than one, use a rotary type as a one-way diverter.

The balancing device ('B) includes a rod (9) that tilts as the load on the load support device (4) increases, and a weight 1194 attached to the rod (9), and the load support device (A) When the K-supported storage tool (1) stores an amount close to the predetermined measurement amount, for example, 90% of the object to be measured,
It is operated by the rod (11) tilted at an angle corresponding to this, thereby actuating the drive machine 01 to maintain the supply amount to the flow dividing device (the storage device n in the state of measuring the odor) at the previously fully opened state. The displacement detection mechanism (8) at the time of supplying a predetermined amount is operated by a switch (S) that operates to reduce the supply amount by a wide margin, for example, to 20%. Apart from that, the rod fl)
The corresponding control mechanism TI') is connected not only to the odor but also to the driver 61 of the flow diverter atr, and at the time of detection, switches the flow diverter a fully open with respect to its storage utensil opening). FIG. 3 is a diagram of each of the load supporting devices.

.

(Km) has meaning only at the start of the weighing operation, and after either one of the detection mechanisms is activated, the common detection mechanism (6)
A corresponding control mechanism (7) controls the entire system.

Next, an example of the operation when the load supporting device, that is, the storage tool (1) is in a hanger position, will be described in detail.

FIG. 8 is a graph showing changes in the supply amount per unit time for the left and right storage tools 11) and fl+, respectively.
In addition, in FIGS. 8 to 7, the balancing device (Bl) is shown in a different positional relationship from the one next to the dormitory for easy understanding.

At the time of starting weighing, the link switching drive mechanism ((2) determines whether the right load support device is linked to the balance device CB1 or the left load support device (Al) is linked to the balance device CB1. They are either in a neutral position with no coordination.

Also, at the same time, the distribution is 100% on the right for mechanism (2), and -0 on the right.
%, right O%, or right 10%.
Furthermore, at the start of measurement, there is no guarantee that there is a normal correlation between the two mechanisms +Cl) and (b); in fact, there are many cases where they are not normal.

However, no matter what the relationship is, the distribution of the flow rate will be different between the right and left sides. Therefore, after a certain period of time has elapsed after the start of measurement, each detection mechanism (Ka) is inevitably activated.

One of (Ka) performs a detection operation before the other. The control mechanism (8) then detects the mechanism (le

However, if it is in its normal linked state 1!1 from the beginning does not transmit and continues the current state as it is.Assume that in this way, for example, the right load supporting device fA) is linked with the balancing device IBIK with priority.

At this time, the vertical frame (4) of the right load support device is cam + l.

%, or right to % and left to 0% [root cause of right side priority].

■ When the predetermined measured amount of deO% is stored in the right storage tool (1), the rod te+ moves away from the switch (S) and closes it. As a result, as shown in Fig. 3, the drive side 1 is activated, and the distribution tool (I4) is displaced so that the ratio is 0% on the right and 10% on the left, and a small amount is distributed to the right storage tool Ill K.
A large amount is supplied to the left storage tool opening).

use

As a result, the control mechanism (Takumi) activates the drive mechanism and as shown in Fig. 4, the flow diverter (12) is displaced relative to the right storage tool (seal) so that it is fully closed. %, left is 700%. At the same time, the control mechanism (linkage switching drive mechanism (0) is operated via the barb, and the rotation axis (6) is rotated once.

As shown in Fig. 5, lift and support the right side frame (4) with the cam +11K, and then move the left side frame (41 away from the cam (6) and its locking portion III) to engage the weight bar fllK. The left load supporting device (A) is then linked to the balancing device (G). This switching to the left hand linkage is memorized in the control device f[FI, and preparations are then made to reverse the direction of action of the drive Ql. After this, remove the full right storage tool and set the empty new one on the right loading table + S1 K:.

[4] When the predetermined measured amount of glue 0% is stored in the left storage tool +1), the rod (11) closes the switch (S).

As a result, as shown in FIG. 6, the distribution of the flow diverter 0 is shifted to the left, 20%, and right 10%.

[5] When a predetermined measured amount is stored in the left storage tool +1), the rod (9) acts on the common detection mechanism (2).

As a result, the flow divider (1) is fully closed to the left storage tool (1) via the control mechanism (F'l) as shown in Figure 7. At the same time, the control mechanism (Vl) Activate the switching drive mechanism (Q and put the right storage tool (1) into the weighing state again. This will return to the [1] (corresponding state). After this, remove the full left storage tool + 1 and replace it with an empty new one. Place it on the left platform (1).

This completes the operation of the cycle, and the cycle is repeated thereafter. The graph in FIG. 8 shows the cosiac μ.

Note that the timing of closing the switch (Sl) can be set at any percentage of the predetermined measured quantity. In addition, the ratio of right and left distribution in the left and right simultaneous supply state is arbitrary. Furthermore, instead of changing the supply amount stepwise as shown above, it may be changed continuously. The storage device may be a bag or a container. In the case of a container, it may be detachable from the platform (8), or it may be fixed and equipped with a discharge gate. The weighing machine may be of any type other than the scale type shown in the example above; for example, it may be a platform scale type as shown in Figure 9. Left and right hanging rods 51, O

Below, I have explained in detail about the implementation process.

The main point W of the continuous weighing device according to the present invention is that a single balancing device (Bl) is provided with a plurality of load supporting devices, and a drive mechanism (Q) that can selectively link and switch between the In the load supporting device diagram of (A), each storage device (1), (1) is connected to a single continuous supply path (2) for objects to be weighed.

When a predetermined amount is supplied to the storage tool (1) in the load supporting device diagram, which is connected to the balancing device (1 ()), the supply to the storage tool (1) can be automatically stopped.

In other words, if the correlation between the link switching drive mechanism (mechanism (2) for weight and distribution is not correct at the start of the weighing record), this can be confirmed and the subsequent corrections performed using the conventional method.
