数する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to the combination counting of items whose individual weights (hereinafter referred to as unit weights) vary slightly, such as bolts, nuts, cups filled with milk, etc. , relates to a more accurate method of counting items.

重を求めることができる。 Conventionally, a large number of items are divided into multiple weighing machines with appropriate variations, and the number of items is calculated by dividing the weight of the item obtained by each weighing machine by the unit weight of the item. There is a combination counting method in which combinations are calculated to find a combination that is equal to or closest to a set number of items, and items are discharged from a weighing machine that corresponds to the combination. In this case, if there is an error in the unit weight, an error will also occur in the calculated number of pieces for each weighing machine, and of course there will also be an error in the combined number obtained by combining the numbers. This will result in inaccurate counting. Also,
The larger the number of items weighed by one weighing machine, the larger the error in the calculated number of items. Therefore, in order to accurately calculate the number of items, it is necessary to accurately determine the unit weight. However, as mentioned above, there are variations in products, so it is meaningless to accurately weigh a single product to find the unit weight. Instead, it is pointless to weigh many products and divide the weight by the number of items. It is better to determine the unit weight by weighing the product, and the more items to be weighed, the more accurately the unit weight can be determined.
また組合せ計数を繰り返していると、時間経過
に従つて品物の単重が全体的に徐々に減少（増
加）することもある。これは例えばミルクをカツ
プに充てんする場合に、ミルクの粘度が周囲温度
の変化によつて変動するために起きる。 Furthermore, when combination counting is repeated, the overall unit weight of the items may gradually decrease (increase) over time. This occurs, for example, when filling a cup with milk, because the viscosity of the milk fluctuates due to changes in the ambient temperature.
従つて計量開始時に適当な手段で数値設定した
品物の単重は計量毎に演算して得られる単重によ
つて、次々と更新するほうがよい。 Therefore, it is better to update the unit weight of the item, which is numerically set by an appropriate means at the start of weighing, one after another using the unit weight obtained by calculating each weighing.

れを先に出願している。 Therefore, in order to achieve this objective, the applicant weighs a large number of items using multiple weighing machines, and calculates the number of items in each weighing machine by dividing the weight measured by each weighing machine by the unit weight. Then, calculate the number of combinations by calculating the combination of each number, find one combination in which the number of combinations is equal to or closest to the set number, and calculate the weight of any one or more weighing machines and the number of pieces mentioned above. We have invented a system that calculates a new unit weight based on the number of items in a weighing machine or multiple weighing machines, and uses this new unit weight when calculating the next number of items, and we have previously filed an application for this.

されて、次回からの組合せ演算に使用される。 Here, we will discuss the new unit weight calculation method in the conventional method. For example, the first method is to take an example of the conventional new unit weight calculation. After the combination calculation, based on the result, when the item is discharged from the weighing machine, whether the weight of the discharged item is equal to the set weight or not. Alternatively, there is a method in which the new unit weight is calculated by dividing the combined weight closest to it by the number of items discharged, that is, the set number. This new unit weight is stored in the calculation control section 4 and used for the next combination calculation.
この他にも新単重算出の方法はいくつかある

精度を逆に低下させる方向に単重の再記憶をする
結果となつている。 There are several other methods for calculating a new unit weight, but all of them involve recalculating and re-memorizing the unit weight for each combination count. However, it is not always the case that the unit weights are approximately the same for each combination count, or that they only change in the same direction of increase or decrease. For example, if the unit weight repeats increases and decreases each time a combination is counted, it is assumed that the unit weight of the items participating in the current combination count changed in the increasing direction (decreasing direction) during the previous combination counting. This means that the unit weight is changing in the decreasing direction (increasing direction), that is, in the opposite direction to the re-memorized unit weight. In this case, the result is that the unit weight is re-stored in a manner that conversely reduces the accuracy when converting the number of pieces.
そこで、本発明は上記問題を解決するためにな

重として再記憶をするようにしたものである。 Therefore, the present invention was made to solve the above problem, and instead of re-memorizing the unit weight for each combination count, the unit weight obtained by n combination counts is stored, and n After the number of times, the average value of the unit weights for the n times is re-stored as a new unit weight for the next n times of combination counting.
このようにして単重の再記憶をｎ回おきに行な
えば個数変換の精度を上げることができる。 In this way, if the unit weight is re-stored every n times, the accuracy of the number conversion can be improved.
以下本発明を実施例に従つて説明する。 The present invention will be explained below based on examples.

行する。 A large number of items are divided into n weighing machines 1 1 ... 1 o , and a start signal a is sent to the calculation control unit 4 from a packaging machine (not shown) that wraps the counted items.
, the arithmetic control section 4 outputs the selection signal b to the multiplexer 2. According to the selection signal b, the multiplexer 2 converts each analog weight voltage input from each weighing machine 11 ... 1o into an A/D converter.
The respective weights that are sequentially input to the converter 3 and A/D converted are stored in the calculation control section 4. The arithmetic control unit 4 divides each stored weight by the unit weight set by the unit weight setting unit 5 (however, the updated unit weight after being updated by the calculated value described later), and rounds the result to an integer. , the weight of the items in each weighing machine 1 1 ... 1 o is converted into the number of items and stored. Next, the arithmetic control unit 4 calculates the number of combinations by adding up the numbers of each weighing machine 1 1 ... 1 o already stored in correspondence with all the combination codes representing the combination of each weighing machine. The combination number and combination code are stored in pairs, and the set number set in the number setting section 6 is compared with all the stored combination numbers, and a combination code with a matching number is searched and stored. . However, if there is no combination with matching numbers, for example, a warning lamp is turned on and the process proceeds to an appropriate error process.

待機状態に入る。 Furthermore, the arithmetic control unit 4 controls each weighing machine 1 according to the combination code whose combination number matches the set number.
1 ...Calculate the combined weight by adding the weights of 1 o , search for a combination of weights that is equal to or closest to the set weight set in the weight setting section 7 from among these combined weights, and select one. Only the combination weight and combination code are stored. Then, this stored combined weight is compared with the upper limit weight set in the upper limit weight setting section 8 and the lower limit weight set in the lower limit weight setting section 9, and this combined weight is not between the upper limit weight and the lower limit weight. If this is the case, for example, a warning lamp is lit and a transition is made to appropriate error processing, and if there is a difference between the two, an ejection signal is outputted from the arithmetic processing section 4 in accordance with the combination code of this combined weight. The items of the weighing machine corresponding to the outputted ejection signal are discharged, and the number of items equal to the set number of items is sent to the packaging machine. At this time, the calculation control unit 4 calculates the unit weight (A) by dividing the weight of the discharged items, that is, the combined weight that is equal to or closest to the set weight, by the number of discharged items, that is, the set number. Calculate and memorize. At this time, there are various methods for determining the unit weight (A) in addition to the first method described above, which will be explained in detail later. This unit weight (A) is not immediately used for the next combination calculation. That is, until n calculation unit weights (A1 to n) are stored, the unit weights that have already been set and stored are used. In other words, when the unit weight is calculated and stored for each combination count, it is determined whether the unit weight has been calculated a preset n times. If the number has not been n times, the unit weight (A) of this time is only stored, and the unit weight for converting the number of pieces is not updated, and the process is shifted to a standby state for the start signal a from the packaging machine. Also, the number of times the unit weight is calculated is n
When the unit weight for the nth time has arrived, add up all the memorized unit weights for n times, divide it by n to calculate the average unit weight (A1+A2+...An)/n, and add this average unit weight to the new unit weight. The unit weight for number conversion is updated and stored as the weight. Note that the unit weight updated at this time is the unit weight set by the unit weight setting section 5 at the time of the first update, and thereafter is the average unit weight calculated last time. Then, the machine enters a standby state again for the start signal a from the packaging machine.
以後、上記動作を繰り返し組合せ計数のｎ回目
毎に新単重を算出して、個数変換用の単重の記憶
更新を行う。 Thereafter, the above operation is repeated to calculate a new unit weight every nth combination count, and update the memory of the unit weight for number conversion.

Therefore, there are various methods for calculating the unit weight after each combination count is completed, in addition to the first method described above, which is the method of dividing the combined weight of the discharged combinations by the number of discharged pieces.

組合せ計数動作も、前述したデジタル式の構成例
の動作と同様に行なわれる。 Although the configuration shown in FIG. 1 above is an example of a configuration in which all data to be handled is once converted into digital quantities and then subjected to arithmetic processing, the present invention can also be applied to a configuration in which arithmetic processing is performed using analog quantities. Of course, the configuration example of the combination counting device in this case is shown in the third section.

However, in this case, since the number of pieces closest to the set number is not necessarily equal to the set number, the unit weight is calculated by dividing the combined weight by the number of pieces closest to the set number.

For each combination counting, the average value of n unit weights obtained by n combinations is used.
Even if there are irregular fluctuations, such as when the unit weight of items participating in combination counting repeats increases and decreases,
Does not reduce the accuracy of number conversion. Therefore, the probability of counting errors in combination counting can be further reduced.
