Abstract

PURPOSE: To improve working accuracy and working efficiency when vegetables are bagged to be delivered by providing an indicating means that indicates whether a weight of the vegetables taken out therefrom is in a range of an adequate quantity or out of the range. CONSTITUTION: A whole weight of vegetables, e.g. spinach including a container loaded on a weighing table 3 is measured to be indicated on a digital indicator 14. Before this stage, a bagging weight thereof to be delivered is determined. For example, a range from 140g to 160g is set by operating dials 6a, 6b based on 150g. An operator grabs the spinach and takes it out in his visual estimation. When the weight of an amount of the grabbed spinach is within the range of 140-150g, a blue indication lamp 15 is turned on, then the operator understands the weight of the grabbed spinach is within the adequate range and bags it. When the weight is not more than 140g, a yellow indication lamp 17 is turned on and when it is not less than 160g, a red indication lamp is turned on, thereby the operator may execute adding work or returning work thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the present invention will be described in detail with reference to the drawings. Reference numeral 1 is a weighing machine main body, and a microcomputer control unit CPU is provided on the lower side.
A built-in box frame 2 is provided, and a weighing platform 3 is provided above it. The weighing platform 3 is supported by a strain gauge of a load cell, and the strain detection amount of the strain gauge is transmitted to the control unit CPU side as an electric signal. The display board 4 is
It is fixed to the upper part of the column 5 standing on the front side of the box frame 2,
This is equipped with a display lamp and an indicator for the measured value and the number of times of measurement.

Further, the box frame 2 is provided with a dial 6 as a measurement adjustment setting mechanism, a dial 7 as a required measurement time setting mechanism, a dial 8 for adjusting a weighing device, and the like.
Further, a petal-type transmitter 9 capable of transmitting a reset signal can be appropriately connected to the control unit CPU.
Further, the defective product weighing device 10 is attached to the weighing device main body 1 and attached thereto.
Is provided, and the signal of the measured value by the weighing device 10 is transmitted to the control unit CPU on the main body 1 side. The defective item weighing device 10 is also composed of a strain gauge using the same load cell as the main body weighing device 1. Reference numeral 12 is a weighing table, and 13 is a dial for adjusting the tare.

The input signal and output signal of the control unit CPU will be described below.
Is provided with a memory unit, a calculation unit, and a timer-function unit, and as an input signal, a signal of the measured value of the weighing object placed on the weighing platform 3, and the defective item weighing device 10 weighs it. The signal of the measured value, the setting signal from the various dials 6, 7 and 8 and the reset command signal from the reset transmitter 9 are accepted, and further, the timer signal for setting the measured time is accepted.

Further, as an output signal, the weighing value of the vegetables separated and taken out for bagging from the shipping vegetables placed on the upper surface of the weighing table 3 for each tare is output and digitally displayed. Indicator 14, output signal to blue lamp indicator 15, which is an indication of an appropriate signal to display when the weighed value of the separated and taken out vegetables is an appropriate amount within the range of a preset target weighed value, an appropriate amount There is an output signal to the red lamp indicator 16 for displaying an unsuitable amount on the increase side and an output signal to a yellow lamp indicator 17 for displaying an unsuitable amount on the decrease side. In addition, this display means is "appropriate amount", "large amount", "small amount" by audio or visual.
It may be a display means such as. Further, an output to the number-of-times indicator 18 for counting the number of times of taking out an appropriate amount is also configured to be output.

By the way, the actual calculation function and display function in the above-mentioned structure will be specifically described. After the power is turned on, the harvested leaf vegetables, for example, a container 20 containing spinach 19 is placed on the weighing platform 3. Place. Further, the container 21 is appropriately placed on the weighing table 12 on the defective item weighing device 10 side. Then, the tare adjusting dial 13 is adjusted so that the tare weight becomes zero.

At the time of this initial setting, the total weight of the spinach 19 including the container 20 placed on the weighing table 3 is measured and displayed on the digital display 14. At least before this stage, the baggage amount for shipping the spinach 19 is determined, and for example, when 150 g is used as a reference, the upper limit side 10 g and the lower limit side 10 g are set as the allowable shipping weight range, the dial is a setting mechanism. 6 is operated to operate from the small amount side 140 g to the large amount side 160 g by operating the small amount set dial 6a and the large amount set dial 6b. Further, by operating the dial 7, the required calibration time suitable for the operator who takes out one predetermined amount at a time is set to, for example, 15 seconds. Then, this setting signal is stored in the memory of the control unit CPU, and this becomes the standard of the work standard.

When the setting of the metering required time setting mechanism by the dial 7 is not performed, a petal type transmitter 9 can be connected in series and manually reset for each stroke. That is, it is possible to switch to a work that is not time consuming by stepping on the petal for each measurement measurement. After these initial settings, work is started. First, in the work for 15 seconds of automatic time setting, the worker grasps the spinach 19 stored in the container 20 with a register. Then, if the grasped amount is within 140 to 160 grams, the "blue" of the display lamp 15 is turned on. Therefore,
The worker may recognize that the spinach 19 thus taken out was within the proper weighing range and confidently put it in a suitable bag.

Then, after a lapse of 15 seconds, the second take-out work is performed. At this time, when the second take-out amount is 140 g or less or 160 g or more, the “blue” of the display lamp 15 does not light up and the value is 140
When the weight is less than gram, "yellow" of the display lamp 17 is turned on, and when the weight is 160 grams or more, "red" of the display lamp 16 is turned on. When this improper amount is displayed, the worker may additionally take out the container 20 or correct the taken-out amount until the "blue" of the display lamp 15 is turned on by the returning work of the extra amount. Then, if this "blue" lamp is turned on in 15 seconds, it may be packed in a bag. Hereinafter, this work is continued to carry out the bag filling work.

In the middle of the work, insect-eating leaves, dead leaves, etc., which cannot be shipped in the case of leaf vegetables, are mixed. In this case, the defective leaf vegetables must be removed and packed in a bag. At this time, if such leaf vegetables that cannot be shipped are mixed in the picked leaf vegetables, they are naturally removed. Then, the removed items are placed in the container 21 placed on the weighing platform 12 on the side of another defective item weighing device 10 without remaining. Then, the weight of the defective vegetables is measured and the signal is sent to the microcomputer control unit CPU, and the weight of the defective vegetables is added, and the total weight of the initial measurement remains as it is, and the grasped amount from this is accurate. Is subtracted from. That is, in this embodiment, the extraction amount is subtracted based on the total weight of the spinach 19 which is the originally set leaf vegetable.

If it is not necessary to calculate how much such defective leaf vegetables are mixed in the whole, it is sufficient to incorporate a means for resetting to a new weight in the control unit CPU at the time-out in the previous time setting. With this resetting means, it is sufficient to always indicate whether the measurement is passed or failed in the first measurement. By doing so, there is no problem even if the defective leaf vegetables are discarded as they are, and the configuration is simplified. Further, if the container 20 to be placed on the weighing table 3 is appropriately separated and a defective product returning portion is provided in advance, it is not necessary to perform another weighing measurement, and the defective leaf vegetables returned to the returning portion is returned. Remains as it is and is weighed on the weighing platform 3, so that another defective item weighing device 1
It is not necessary to set 0.

During the work, when the work set time is not appropriate, for example, 15 seconds, the work can be changed to 10 seconds or 20 seconds by appropriately adjusting it according to the suitability of the operator. Further, if the microcomputer control unit CPU is provided with an automatic learning rewriting means, the state of the working speed of the worker is written every time the work is performed, and the automatic working time setting taking into consideration the margin time on the safe side is based on this. Can be configured to be If a means for displaying this automatic set time to the operator with another digital display is provided, it can be used as a guide for the work speed of the operator and the work can be performed efficiently.

Further, if the means for transmitting the reset signal from the side of the petal type transmitter 9 which is another manual type reset device to the control unit CPU is used, the work can be adjusted to one's own pace. It will be very useful when there are too many bad leaf vegetables and the bagging work time is uneven and there is no guide. At the end of the work, if the first defective product measuring means is provided, the yield of the shipped amount can be immediately known. Also, the number of bags packed in the shipping bag can be known by the number of times indicator 18 which counts the number of times of taking out an appropriate amount.

[0017]

According to the present invention, when the leaf vegetables are packed in a bag and shipped, the operator grasps the grasped amount on a weighing machine as in the conventional case, and an operator determines whether or not it is within an appropriate range. Without making a judgment, it is possible to very easily measure the weight within a determined range and display the appropriate amount and the inadequate amount to the operator to improve the work accuracy and work efficiency.
