Abstract

PROBLEM TO BE SOLVED: To prevent a shutter from being left open after weighing operation by energizing a solenoid by turning off a power switch provided on a control panel, retreating/advancing a shutter arm via a reciprocating member and fully closing a supply port with the arm releasing from the shutter side. SOLUTION: A power switch provided on a control panel is electrically connected with a solenoid 7. If good brown rice in a reservoir tank 1 runs out during weighing and weighing operation is finished, a shutter 3 keeps fully opened or partially opened. At this time an off-button of the power switch provided on the control panel is pressed, whereby the solenoid 7 is energized, and a shutter arm retreats/advances via a reciprocating member 6 and releases from the shutter 3 side. Then the shutter 3 is released from a state of keeping fully opened or partially opened to have a supply port 2 fully closed. Thus the shutter 3 can be prevented from being kept open after weighing operation is finished.

[0002]

2. Description of the Related Art As described above, a reciprocating member which operates via a solenoid by measuring a set amount of a weighing scale is connected to a shutter arm, and the shutter arm is retracted with its upper end serving as a fulcrum. The applicant has developed and prototyped an automatic cereal weighing machine in which the shutter is switched between full opening, partial opening, and full closing by releasing / engaging the shutter with the arm. However, in the configuration of this prototype, there is no mechanism for fully closing the shutter except during weighing, so the shutter may be left open after weighing,
In addition, what is trapped in the storage tank or the like at the start of the work is scattered from the supply port.

[0003]

As described above, the prototype developed last time has no mechanism for fully closing the shutter except at the time of weighing. Therefore, the shutter is left open after the weighing operation. In addition, there are drawbacks such as those that are trapped in the storage tank or the like at the start of the work and are scattered from the supply port. It was an attempt to embody a good one and led to an improvement.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a shutter provided at a supply port at a lower portion of a storage tank, and a shutter provided at a lower portion of the storage tank in order to solve the drawbacks described in the preceding paragraph and to realize a product which is easy to handle. A shutter arm having an upper end pivotally attached to a support attached to the lower side, and a reciprocating member that operates via a solenoid by measuring a set amount of a weighing scale, and the reciprocating member is connected to the shutter arm. The shutter arm is retracted with the upper end as a fulcrum, and the supply port is fully opened / partially opened / closed by the detachment / engagement of the shutter arm with the shutter.
When the power switch is fully closed, a power switch provided on an operation panel is electrically connected to the solenoid, and the power is supplied to the solenoid by an "OFF" operation of the power switch to retreat a shutter arm through a reciprocating member to release a shutter. The supply port was completely closed by separating from the nipple.

With this configuration, when the shutter is fully opened in the weighing operation, the shutter arm is engaged with the shutter to maintain the fully open state, and the grains in the storage tank fall from the supply port. When the grains are supplied into the bag and the grains in the bag reach the set amount, the solenoid is momentarily energized and the reciprocating member moves forward, and the shutter arm disengages and the shutter is released from the frame. The shutter moves down due to its weight. At that time, the shutter arm moves back and the moving down shutter engages with the alligator to hold the supply port partially open, so that the shutter is moved little by little. When the cartridge is dropped from the supply port and packed in a predetermined amount in the bag, the solenoid is energized and the reciprocating member moves forward and separates from the shutter, and the shutter fully closes the supply port.

As described above, the supply port is fully opened / partially opened / closed completely by the shutter, and the set amount is sequentially packed in a bag. Even when the operation is completed, the shutter is maintained in a fully opened state or a partially opened state. So, at the end of this work,
The power switch provided on the operation panel is turned "OFF". Then, the solenoid is energized, the shutter arm retreats via the reciprocating member, the shutter is released from the arm, and the shutter is released from the open state, and the shutter is fully closed. If the main power supply is subsequently turned "OFF", the reciprocating member moves back and the shutter arm also moves back.
