Next, the operation of the automatic weight sorter will be explained.

(1) Main program operation of external control device 29.

This main program operation kJ1 As shown in FIG. 8, upon receiving the start command F1, the equipment 29 is set to the initial state F2. At this initial setting edge, the CPU 66 performs processing for menu selection F3 according to a predetermined zologram. That is, the CPU 66 reads the data of each function setting item A to E from the ROM 67 or the like, and displays it on the display device 62 via the peripheral controller 4. Here, when the operator selects one function setting item from the display menu of the display device 62, the CPU 66 receives this selection data and reads out the contents of the one function setting item from the ROM 67 etc. 6

The CPU 66 transmits one function setting item data selected from the menu and one data or change data selected from the one function setting item data through the data transmission F4 via the interface 69.
11t, it is sent to the sorting machine main body 2I side. When the sorting machine main body 21 receives change data from the external control device 29,
Rewrite the specific peaks and valleys of the item. Therefore, the sorting machine main body 21 performs weight sorting of the objects to be weighed on the basis of the rewritten data.

(2) Program operation of the sorting machine main body 21.

In this operation, as shown in FIG. 9, upon receiving a start command G1, the sorting machine main body 2Z is set to an initial state G2. After this initial setting, the CPU 43 performs a self-diagnosis G3 to determine whether the sorting machine main body 2I is normal or not. If it is abnormal, the CPU 43 outputs an abnormality processing G4, for example, an alarm, and also outputs an alarm signal to an external control device. 29 is also transmitted to indicate that there is an abnormality. On the other hand, if it is normal, the internal parameter reading operation G5 is performed. This internal/e parameter reading G5 is for reading parameters (setting values) necessary for heavy-M-selection from among the function setting items A and E from the ROM etc. 44-46. When this internal parameter reading operation G5 is completed, external data reading G6 is performed. This external data 1 backlash G6 is an operation to read necessary data from the external control device 29, as will be specifically explained in section (3) below, and when this operation is finished, key manual processing G7 Go to Z. This key manual processing G7 is based on data obtained from the weighing machine line and other places, such as the run-up section 23, h.
This is a process to check whether the drive motors of the I-Makotsu unit 24, sorting unit 26, etc. are operating properly.

When each operation is completed as described above, necessary data processing 08 and the like are performed using the data obtained from each operation to control each component of the weight sorting machine. The control of each component includes, for example, the number of sorting stages, sorting direction, instruction method, operation sequence, timer time, function mode,
Standard values, etc. will be raised. Specifically, the number of sorting stages is a control that sorts the objects into three or more stages depending on the weight of the objects to be weighed, and the sorting direction refers to the direction in which the objects to be weighed at each stage are discharged. It is the control of what is done. The indication method is '0: rJIliIh1° object measurement indication range, scale interval, decimal point, unit (kgl, li', l1li; II)
This is a control to set. The operation sequence means, for example, the setting suppression of non-stop weighing, stop weighing, pulse sorting, and hold sorting, and the timer setting for one hour is the run-up time of the object to be weighed,
Setting control for weighing time, discharge time, etc., and function modes include, for example, preset settings, deviation value/absolute value setting control, reference values, etc., and setting control for reference weight, upper/lower limit values, target dismissal button, etc. A series of these setting controls is then given to the necessary components at various locations. Furthermore, the data processing G8 performs various processes when actually measuring one view of the object to be measured, such as M (resistance 6111 constant value, pass/fail determination, etc.) and outputs these 6111 constant results, determination results, etc. .

After the data processing in G8 is performed, necessary display processing G9 is performed, such as displaying one view, displaying the number of objects, and displaying an abnormality.

(3) External data reading routine in the sorting machine main body 2I.

The sorting machine main body 2I reads external data at G6 in FIG. 9, and this reading operation is performed according to the routine shown in FIG. 10. That is, when the CPU 43 of the sorting machine main body 2Z proceeds to the external data reading G6 according to the predetermined zologram, it first determines whether or not it is the reading G62 of the operation function setting item A, and then proceeds to the reading G62 of the item A.
If so, the external control device 2 via the interface 50
A request signal for reading the operational function setting items is sent to the CPU 66 of 9. Here, the CPU 66 of the external control device 29
reads the necessary data from the operation function setting items based on the request signal from the sorting machine main body 2 and sends it to the sorting machine main body 21 via the interface 69. The CPU 43 reads the operation function setting item data -7/, G63. After reading this data, the CPU 43 proceeds to the next step and determines whether it is the correction data generation item G64, and then selects the correction data generation item B. For reading, a request signal is similarly sent to the external control device 29 via the interface 50, and the correction data is read G65.After reading the correction data,
Correction processing is performed based on this correction data.

After this correction processing, the CPU 43 determines whether or not a diagnostic processing item is to be read G66, and if the item is to be read, data necessary for the diagnostic processing is similarly read from the external control device 29 and the diagnostic processing G67 is performed. Using the same procedure, determine whether the reference value etc. setting item C is read G6B,
If the item C is read 06B, the external side (FFJ1 equipment 29 reads data such as necessary reference values). Data processing G in Figure 9

68, etc., and if data needs to be changed, the change data is input and one data change is performed. When the data change processing is completed, the data is stored in the RAM 29 and transmitted to the sorting machine main body 21 side. Weighing instruction range/scale interval A21, operation sequence AJ7. A similar routine is performed when special function A41 is selected.

(5) Routine for correction data generation item B in external control device 29.

This operation is also performed after the correction data generation item B is selected by menu selection F3 in FIG. 8, and specifically, it is performed according to the processing routine shown in FIG. 12. That is, this correction data generation is performed after selecting correction data generation item B by performing linearity correction, for example, on the display device 62tlC.
Characters such as scale temperature correction and indicator temperature correction are displayed. After selecting one of the display contents, for example, straight spinning correction BII, by menu selection Bl,
When the number of correction points is set, a correction curve is displayed according to the points, so input correction data to each correction point while looking at the display. When this correction data is input, a correction calculation is performed in row 1g based on this correction data, and after this calculation, error curves before and after correction are displayed.

If it is determined from this display content that it is OK, that is, the correction data generation has ended, the operator returns to menu selection B1. Scale temperature correction B21. Follow the same procedure for indicator temperature correction.

(6) Routine for setting reference values, etc. of the external control device 29.
