DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing device for weighing an object to be weighed to a predetermined amount.

[0002]

2. Description of the Related Art Normally, a scale is used to measure an unknown quantity such as a weighing scale, for example, and a predetermined quantity to be used, for example, when packing food or the like into bags or boxes. There are two main purposes, namely, weighing a sample. In the latter case, for example, a weighing device 1 as shown in FIG. 9 is used. The weighing device 1 includes a weighing unit 2 having a mounting table 2a on which an object to be weighed S 'is placed, and a support 3 at the center thereof.
And an indicator 4 provided with a display unit 4a for digitally displaying the weight of the object to be weighed. The operator places the object to be weighed S ′ on the mounting table 2a while holding the display unit 4.
The value of “a” is read, and the amount of the weighing object S ′ on the mounting table 2a is adjusted so that the value shown on the display unit 4a falls within the target weight range. Then, when the range of the target weight is displayed on the display unit 4a, the operator determines that the weight of the object S ′ placed on the mounting table 2a has reached the target weight,
Complete weighing.

[0003]

That is, in the weighing operation, the operator places the display 4 of the weight of the object to be weighed on the mounting table 2a.
While reading the value of a, it is determined whether or not the weight is within the target weight range based on the value, and the weight of the object to be weighed is adjusted. Usually, such work is repeated tens of times, hundreds (in some cases, thousands) times a day, and is performed for a long time. That is, you need to watch the digital display many times,
For example, work efficiency deteriorates due to eye fatigue and the like. Also,
The operator must remember the allowable range of the target weight of the object to be weighed.
At that time, the allowable range of the target weight is mistakenly determined to be the weighing completion, and the object to be weighed, which is supposed to be weighed, may not have a weight within the target weight range.

[0004] The present invention has been made in view of the above problems, and has as its object to provide a weighing device capable of reliably weighing a predetermined amount and improving the work efficiency.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a weighing unit for measuring the weight of an object to be weighed, comprising a mounting table for placing the object to be weighed, and a weighing unit arranged above or beside the weighing unit. A detection unit that is lit based on the output of the weighing unit, and a reception unit that receives a signal from an operation unit or a computer, wherein the detection unit is at least mounted on the mounting table. A first lighting unit that lights up when the weighed object is within the target weight range and a second lighting unit that lights up when the weighed object placed on the loading table exceeds the upper limit of the target weight. And a lighting unit, wherein the signal received by the receiving unit is a signal for setting at least an upper limit and a lower limit of the target weight.

[0006] Further, the above object is to provide a weighing unit having a mounting table on which an object to be weighed is placed, and measuring the weight of the object to be weighed.
A detection unit disposed above or to the side of the weighing unit and illuminated based on the output of the weighing unit, and a receiving unit for receiving a signal, wherein the detection unit is at least the cradle. A first lighting unit that lights when the weighing object placed on the weighing object is within the range of the target weight, and when the weighing object placed on the loading table exceeds the upper limit of the target weight. A plurality of first weighing device units having a second lighting unit for lighting;
A weighing device characterized by comprising at least an operating unit or a computer for transmitting the signal for setting an upper limit and a lower limit of the target weight.

That is, when the first lighting section is turned on, it can be seen at a glance whether or not the weight of the object to be weighed is within the target weight range. Since it can be seen at a glance that the upper limit of the target weight is exceeded, it is not necessary to read the numerical value of the weight. Further, when the second lighting unit is turned on, the weight of the object placed on the weighing unit exceeds the target weight range, so that the weight of the object is reduced, and the first lighting unit and If the second lighting section does not light up, the weighing object placed on the weighing section has not reached the target weight range, so that it is possible to immediately increase the weight of the weighing object. it can. That is, it is possible to immediately determine how to adjust the amount of the weighing object placed on the mounting table in the lighting state of the first lighting unit and the second lighting unit, so that the adjustment of the weighing object can be quickly performed. It can be carried out. That is, work efficiency can be improved. Further, since the range of the target weight is determined by receiving a signal from the operation unit or the computer, the operator reads the numerical value of the measured weight of the object to be weighed, and based on the numerical value, the object is weighed based on the target weight. Since it is unnecessary to determine whether or not the weight is within the range, the weighed object can be surely within the range of the target weight.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, there is provided a mounting table for placing an object to be weighed, a weighing section for measuring the weight of the object to be weighed, and a weighing section disposed above or beside the weighing section. A detection unit that is turned on based on the output of the weighing unit, and a reception unit that receives a signal from an operation unit or a computer, wherein the detection unit is at least an object to be weighed placed on the loading table. A first lighting section that lights up when the weight is within the target weight range, and a second lighting section that lights up when the object placed on the loading table exceeds the upper limit of the target weight. A second lighting unit that has a signal received by the receiving unit and that is turned on when exceeding the weighing device limit, wherein the signal is a signal for setting at least an upper limit and a lower limit of the target weight. And a weighing device having: Alternatively, there is a weighing unit for measuring the weight of the object to be weighed, which has a mounting table for placing the object to be weighed, and a detection device that is disposed above or beside the weighing unit and is turned on based on the output of the weighing unit. A first lighting unit, which comprises a unit and a receiving unit that receives a signal, wherein the detecting unit is lit at least when the object placed on the mounting table is within the target weight range, A plurality of first weighing device units having a second lighting unit that is lit when the object placed on the mounting table exceeds the upper limit of the target weight;
The weighing device includes at least an operating unit or a computer that transmits a signal for setting an upper limit and a lower limit of the target weight.

With such a weighing device, the first lighting section of the detection section turns on the light to indicate that the object to be weighed is within the target weight range, and the second lighting section turns on the lighting section. It can be seen that the weighing object exceeds the upper limit of the target weight, and the first lighting unit and the second lighting unit do not light up, so that the weighing object is below the lower limit of the target weight,
You can see at a glance. Therefore, it is possible to immediately understand how to adjust the object to be weighed on the mounting table in the lighting state of the first lighting section and the second lighting section, and to immediately adjust the weighing object to the target weight range. Therefore, work efficiency is improved. In addition, it is not necessary to read the value of the weight of the object to be weighed in order to keep the object to be weighed in the range of the target weight. It is not necessary to determine whether or not to do so. Therefore, even if the work of setting the object to be weighed within the target weight range is repeatedly performed for a long time, the fatigue is far reduced, and the working efficiency is not reduced as compared with the conventional case. Further, since the range of the target weight is determined by a signal from the operating unit or the computer, the operator (which is an operator observing the detection unit of the weighing device) has the object to be weighed within the range of the target weight. Since it is not determined whether or not the object is weighed, the object to be weighed can be more reliably measured within the range of the target weight.

If the weighing device has a plurality of first weighing devices, the operating unit or the computer may set the upper and lower limits of the target weight of the plurality of weighing devices to one first weighing device. A configuration that is set for each unit (for example, a configuration that is set when the operation unit is pointed at the receiving unit of the first weighing device unit such that the transmitting unit of the operating unit is directed to the receiving unit of the first weighing device unit, such as a remote controller of a television). Alternatively, they may be set collectively. To set them all at once,
For example, when the same weighing operation is performed at a plurality of locations, it takes almost no time to set the first lighting unit and the second lighting unit, and there is a mistake that only a certain weighing device unit has different set values. This does not occur, and the object to be weighed can be reliably weighed at any point in the range of the target weight. In the case where the first weighing device section is set one by one by the operation unit, the set values of the upper limit and the lower limit of the target weight are not changed until the operation unit performs a predetermined operation. If the value of the set value is maintained even if the set value is transmitted, the same effect as when collectively set can be obtained without setting all the first weighing devices at once. be able to.

In the present invention, the signal received by the first weighing unit or the receiving unit of the weighing device may be either wireless or wired, and may be received by both wireless and wired. Is also good. When the set value of the target weight is transmitted to each first weighing device unit via the computer or from the computer, the computer turns on the first lighting unit, the second lighting unit, or the third lighting unit. By collecting information such as the number of times, it is also possible to know the object to be weighed that has reached the target weight, that is, the weighed number. When the target weight is set by the operation unit or the computer, it is preferable to provide a display unit together with the setting unit so that the set value can be confirmed at the time of setting.

When the weighing device has a plurality of first weighing devices, the weighing unit having a mounting table for measuring the weight of the object to be weighed and the weight of the object to be weighed on the mounting table in a digital value are measured. A display unit for displaying, a setting unit for setting an upper limit and a lower limit of the target weight, and a transmitting unit for transmitting the upper limit and the lower limit of the target weight set by the setting unit to the first weighing device unit. If the second weighing device is provided, the weighing device can be calibrated as necessary, and the set value can be changed. In addition, one of these first weighing device units
Finally, if the function of the second weighing device is also used, the weighing device can be calibrated as necessary without increasing the structure of the weighing device having the plurality of first weighing devices. The set value can be changed. Also, the first
The target weight at which the lighting section or the second lighting section is lit may be set by providing a setting section in the operation unit or the computer.

Further, if the detecting section of the above-mentioned weighing device is provided with a third lighting section which is lit when the shortage of the target weight is less than a predetermined amount below the lower limit of the target weight in the vicinity of the target weight range, Until the third lighting section is turned on, the object to be weighed may be increased by a large amount, and after the third lighting section is turned on, if the object to be weighed is increased little by little, the work efficiency is further improved. be able to. In addition, a fourth lighting unit that lights up when no object is placed on the mounting table and turns off when the weight of the object is within the target weight range may be provided. In this case, the fourth lighting unit may be provided. Since it is known that the object to be weighed is within the target weight range by the lighting and the turning off of the fourth lighting unit, the object to be weighed can be more reliably weighed to the target weight. Note that the third lighting section and the fourth lighting section may be provided with either one or both of them. It is needless to say that the weighing device of the present invention may have a function similar to a known weighing device, for example, a function such as a known tare subtraction or a known zero point correction.

Further, the first lighting section, the second lighting section, the third lighting section and the fourth lighting section may be constituted by one corresponding lamp, but each of the first lighting section, the second lighting section, the third lighting section and the fourth lighting section is constituted by a plurality of lamps. Of course, such a configuration may be adopted. Further, the detection unit of the present invention may be provided with a lighting unit that lights up, for example, at a constant weight. For example, as shown in FIG. 8, nine lamps are provided as the detection unit 69,
The rightmost ramp 62 'and the second ramp 6 from the rightmost
2 is a second lighting section, a third lamp 61 'from the right end
And the fourth lamp 61 from the right end as the first lighting unit,
Also, the leftmost lamp 64 is the fourth lighting section,
Although the center lamp 63 is provided as the third lighting unit, the detection unit 69 may be further provided with lamps 65, 66, and 67. At this time, the lighting section 65,
Reference numerals 66 and 67 denote lamps that are turned on when the lamp 63, which is the third lighting unit, is turned on at, for example, 4/5 of the target weight, at every 1/5 of the target weight. For example, when the lower limit of the object to be weighed is set to 200 g using the detection unit 69, the lamp is turned on as follows. First, when the weighing object is not placed on the loading table,
The lamp 64 lights up. Next, when the weight of the object exceeds 40 g, the lamp 65 is turned on.
Is turned on, and the lamp 67 is turned on when the object to be weighed exceeds 120 g. When the object to be weighed exceeds 160 g, the lamp 63 is turned on. Thus, this lamp 65,
By referring to which of the lamps 66, 67, and 63 is turned on, it is possible to understand a guide of how much more should be increased until reaching the target weight.

When the detector 69 is used, the lamps 61 and 61 'are turned on when the target weight is reached, and the lamp 64 is turned on.
Turns off. At this time, the lamp 61 and the lamp 61 'may be turned on at the same time. For example, the lamp 61' is turned on when the target weight is close to the lower limit, and when the target weight is close to the upper limit. You may do so. When the target weight exceeds the upper limit, the lamp 6
2 and 62 'are turned on. In this case, the lamp 62 and the lamp 62' may be turned on at the same time when the target weight is exceeded. If it is significantly different from the above, the lamp 62 'may be turned on. In addition, like the detection unit 69 in FIG.
When a plurality of lamps are used, a lamp that is lit with a slightly smaller weight when the object to be weighed has a certain weight (for example, when a weighed object weighs 130 g, the lamp is lit at 120 g) Lamp 67) may be turned on, or all the lamps (in this case, lamps 65 and 66) which are turned on at a lower weight may be turned on.

When the first lighting section, the second lighting section, the third lighting section, or the fourth lighting section includes a plurality of lamps, the first lighting section is turned on, and the second lighting section is turned on. A partition may be provided between the lamp, the lamp that lights up as the third lighting unit, and the lamp that lights up as the fourth lighting unit, to make it easier to see which lighting unit the lighting lamp is lighting. Good. That is, for example,
As shown in FIG. 8, it is preferable to provide a partition B (this may be a simple line described on the detection unit 69 or a wall protruding toward the worker).

Further, the first lighting section, the second lighting section, the third lighting section, and the fourth lighting section may be lit in the same color with, for example, a white light bulb. The first lighting unit that lights when the weight is within the target weight range is green, the second lighting unit that lights when the object exceeds the upper limit of the target weight is red, and the first lighting unit is a predetermined amount from the lower limit of the target weight. Hereinafter, the third lighting section, which is a point when it is insufficient, may be lit in different colors, such as yellow. When the lamps are illuminated with different colors in this manner, especially when the first lighting unit, the second lighting unit, the third lighting unit, and the fourth lighting unit are formed of a plurality of lamps, it is more clear which lighting unit is lit. , Become clear.

As described above, according to the weighing device of the present invention, it is not necessary for the operator to read the numerical value of the weight of the object to be weighed. It is not necessary to determine whether the weight is within the target weight range. In addition, since the first lighting section or the second lighting section is lit and both the first lighting section and the second lighting section are not lit, the weight of the weighing object placed on the mounting table is reduced. Can be easily and immediately understood. Therefore, the work efficiency of the weighing work can be improved. Further, since the operator does not judge whether or not the object to be weighed is within the range of the target weight, the object to be weighed can be more reliably measured within the range of the target weight than before. .
