Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to extracting a desired weight of granules from a hopper which stores the granules supplied by the calyx.

When weighing and bagging granular materials, the amount is increased or decreased relative to the target weight e depending on the dryness of the granular materials. Increases or decreases in quantity compared to this standard W mode are carried out by the operator's settings at the start of weighing. If the power is turned off for this reason, the above-mentioned increase or decrease settings will be lost. Therefore, if you restart the work, the amount will be increased again or pi:
I have to go back and forth with the weight loss settings, but sometimes I forget to reset them.

This invention solves the inconvenience of @ and is constructed as follows. That is, a hopper (11 (

In a weighing and bagging device that is provided with a shutter (13) through FI M, and which bags granular materials of a desired weight by appropriately operating this shutter (3), 3) is provided to link the control circuit (61, u) to the hopper mouth by turning on the confirmation switch (8) that displays the supply amount control value of the control circuit (61 on the display (7)). This invention, which has a control circuit that can start the drive motor (M) of the supply mechanism (9) for supplying granular materials, has the following technical effects. The confirmation switch (8) must be turned ON in order to activate the filling device, and at this time, check the supply amount control value, that is, the bagging weight displayed on the display (7), and press S. Therefore, even when resuming business, there will be no omissions in checking the bagging weight, and it will be possible to bag the desired weight accurately.
The specific configuration of this invention will be explained with reference to embodiments shown in the drawings.

The weighing and bagging device used in this embodiment is a vertical granule sorter, as shown in Figure t. To explain the general operating state of this vertical granule sorter, the granules inputted from the input hopper 00) are lifted into the granule sorting mechanism 1 which is the feeding mechanism (9).
While being sorted in this way, the large-diameter particles are transferred to hopper C1)
One is sent. In the hopper 0), the opening and closing of the shutter 13) at the outlet (2) is controlled by the operation of the solenoid 1', and the sized particles are fed into the tare bag 0 at a set weight.

(4) is a scale, (7) is a display that digitally displays the weight signal from the scale (41), and (M) is a motor that drives the lift sorting mechanism (9).

The electrical connection in this embodiment 1 has a circuit structure as shown in FIG. 2 or 3. Next eko,
The configuration and operation mode of this circuit will be explained.

First, see Figure 2.

are both tp,=, and the contacts R2-ax form a self-holding circuit. In addition, the contact R2-a2 is closed, so that the control circuit (6) becomes conductive and the solenoid 01) starts operating. When the shutter 13) of the hopper 111 is opened and the tare 02) on the weighing scale (4) is supplied with this cane, the weight of the particles in the tare (2) reaches the desired setting.
When this is reached, solenoid 01) is activated and the shutter (3) is activated.

In the embodiment described in mI, a circuit is constructed using a plurality of relays. However, it is also possible to change to an appropriate implementation means, such as implementation using a non-contact circuit.
