Description

Description: TECHNICAL FIELD The present invention relates to a quantitative assortment weighing machine for obtaining a fixed amount of weight by combination.

(Prior art) When packing foodstuffs such as side dishes in a certain weight, a quantitative assortment weighing device may be used.

This quantitative assortment weighing machine separates small food items such as fried foods and processed foods into weighing pans of multiple scales,
In the case of seafood, one to several fish (pieces) are placed and the weight obtained from each scale is sent to the arithmetic unit. The arithmetic unit executes a combination calculation based on each weight value obtained by each of these weighing devices. , The optimum combination for the set value is obtained, and a signal is sent to the indicator attached to the corresponding measuring instrument to display that the measuring instrument is selected as the optimum combination. The operator removes the item placed on the scale and packs it in a container or the like according to the display of the indicator.

(Problems to be Solved by the Invention) In such a quantitative assorted weighing instrument, the combination is completed, and a lighting instruction signal is output to the indicator of the scale selected for the combination, for example, the indicator lamp, and the lighting is constant. Hold for time. Then, the hold is released on condition that all the items are removed from each scale and the weight returns to zero or minus.

However, if a small amount of residue such as an article, especially a side dish, remains on the balance, the hold state is not released, and there is a problem that the next process cannot be performed.

Therefore, the present invention provides a platter weighing machine for the purpose of solving the problems of the prior art.

(Means for Solving Problems) The quantitative assortment weighing machine of the present invention is configured as follows. That is, target weight setting means for setting the target weight in advance,
Means for detecting the weight of each item placed on a plurality of weighing scales, means for executing a combination calculation based on the detected weights according to a predetermined combination pattern, and each scale being provided with a target weight. On the other hand, an instruction means for displaying that the optimum combination has been selected, a means for holding the display for a certain period of time on the selection instruction means, and a weight value of the balance after the item is removed from the balance is smaller than a preset value. In this case, a control means for sending a signal for releasing the hold is provided.

(Operation) In the quantitative assortment weighing machine of the present invention, the display hold of the indicator provided corresponding to the balance selected as the optimum combination for the target weight is set to a value near zero when the weight is preset by removing the item. Since it is canceled on condition that it becomes smaller than the value of, the weighing process can be performed efficiently.

Example An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of the assorted weighing machine of the present invention.

In the figure, W _{1 to} W ₁₀ are scales for weighing articles, L _{1 to} L ₁₀ are indicators such as indicator lights, A is a weight sensor such as a load cell provided for each scale, B is an A / D converter, C is I / O port, CPU,
A controller provided with a memory, a bus line, etc., D is an input device such as a keyboard, E is a display device, F ₁ is a carry-in conveyor, F ₂ is a carry-out conveyor, G ₁ and G ₂ are worktables, P ₁ , P ₂ is a worker.

This platter weighing machine operates as follows. the first,
The control device is set to the registration mode by the function key from the input device, the product name code and the target weight are set for each product to be weighed, and the product name code and the target weight are stored in the registration area of the memory. Before starting weighing, the input device inputs the product name code to call the target weight, and sets the control device to the weighing mode.

When goods to be weighed is loaded on a workbench G ₁ from input conveyor F _1, the operator P ₁ balance W ₁ and especially the articles by a suitable amount
~ Place on W ₁₀ . The weight of the item placed on each scale is detected by the weight sensor A, converted into a digital signal by the A / D converter B, and input to the control device C. The control device C executes a combination operation according to a predetermined pattern,
Set the balance that is the optimum combination for the target weight,
It is attached to the balance from the indicator signal line indicator L ₁ ~L
_A signal is sent to ₁₀ , and the indicator, for example, the indicator lamp is turned on for a certain period of time. The worker P ₂ removes the item from the scale corresponding to the display on the indicator, performs packing processing on the work table G ₂ , and carries out the packed item from the carry-out conveyor F ₂ .

In the present invention, the hold release of the indicator is determined when the weight near zero, which is preset in the scale, becomes 5 g, for example, so that the indicator display can be displayed even if the remnant is placed on the scale. It is characterized in that it is erased so that the next process can be performed. The range in which the hold can be released is set by the input device. Also, this set value can be changed, and depending on the type of item,
It is possible to arbitrarily set the residual allowable range of the residue, for example, the higher the unit price, the narrower this setting range to reduce the loss due to measurement, and the lower the unit price, the larger the setting range, We can speed up weighing work.

FIG. 2 is a flowchart showing the processing procedure of the present invention. Next, this flowchart will be described.

(1) Initialize settings such as hold release weight (step S ₁ ) and input weight data from all scales, for example, 10 scales (step S ₂ ). Then run a combination calculation (Step S _3), the combination of optimal checks whether established for target weight (step
S ₄ ). If the combination is not established, the processing of step S ₁ and subsequent steps is repeated until the combination is established.

(2) If the combination is established, the combination weight and the indicator corresponding to the scale, for example, the lighting of the indicator lamp is held (step S ₅ ), and the item is removed from the scale (step S ₅ ).
S ₆ ).

(3) combination enter the weight data from the scale that participated (step S _7), to check whether a specified weight or less input data of a certain balance is set (step
S ₈ ). If the determination is NO, the operator performs a process such as the removal of residue from the balance, performs the process of step S _7, S ₈ again. If less specified weight by weight data of the scale is set, to check whether a specified weight or less by weight of the subsequently joins the combination weigher is set (step S _9), the determination is familiar with YES if releasing the hold (step S _10).

Here, the designated weight for releasing the hold should be narrowed by an input device, such as a numeric keypad, to increase the accuracy by increasing the unit price and increase the working speed by decreasing the unit price. , Any value depending on the item to be weighed.

Although the gist of the present invention has been described above with reference to the specified embodiment, it is apparent that various changes and modifications can be made to the present invention based on what has already been described.

(Effects of the Invention) As described above, in the quantitative assorted weighing machine of the present invention, the display hold of the indicator corresponding to the scale selected in the optimum combination with respect to the target weight is preset to the weight obtained by the scale. Since it is canceled on condition that the weight has become less than or equal to the designated weight set to around zero, the conventional condition that the remaining state of the item is placed on the scale and the hold state continues and the subsequent processing cannot be executed. Technical problems can be solved and efficient weighing can be performed.
