It has become so.

  The weighing conveyor 32 conveys the inspection object under predetermined conveying conditions. Further, the object W to be inspected is conveyed to the sorting section 5 in the subsequent stage after being weighed and sorted.

  The transport unit 3 is composed of a run-up conveyor 31 and a weighing conveyor 32. The run-up conveyor 31 runs the test object W before the test object W conveyed from the preceding belt conveyor 14 moves to the weighing conveyor 32. The run-up conveyor 31 includes two rollers 31a and 31c and these rollers. And an endless conveyor belt 31b wound around the roller.

  The weighing conveyor 32 is supported above the weighing unit 21 that weighs the inspection object W, and includes two rollers 32a and 32c, an endless conveyor belt 32b wound around these rollers, and a roller 32c. It is configured by a motor (not shown) that is driven. The roller 32c is driven to rotate by driving a motor.

  The carry-in sensor 4 is arranged between the run-up conveyor 31 and the weighing conveyor 32, and is composed of a transmission type photoelectric sensor including a pair of a light projecting section 4a and a light receiving section 4b. The light projecting section 4a is arranged on the apparatus main body section 2 side of the conveyor belt 32b. The light receiving section 4b is arranged on the other side surface side of the conveyor belt 32b so as to face the light projecting section 4a.

  The carry-in sensor 4 starts the carry-in of the test object W by the test object W passing between the light projecting section 4a and the light receiving section 4b and the light receiving section 4b being shielded by the test object W. It is designed to detect The carry-in start signal detected by the carry-in sensor 4 is output to the overall control unit 7 in the apparatus main body 2.

  The weighing unit 21 is a load sensor that supports the weighing conveyor 32 and outputs a weighing signal based on the load due to the mass of the object W to be inspected. The weighing unit 21 is composed of a weighing mechanism such as an electromagnetic balance mechanism, and the object W to be inspected is weighed. While being conveyed by the conveyor 32, the load applied to the weighing unit 21 is measured. The weighing unit 21 may be any weighing mechanism that can measure the weight, and may be configured by a weighing mechanism such as a differential transformer mechanism or a strain gauge mechanism.

  The comprehensive control unit 7 includes a signal processing unit 71, a weighing unit 72, a storage unit 73, a control unit 74, and a pass / fail judgment unit 76.

  The signal processing unit 71 receives the weighing signal from the weighing unit 21 and performs signal processing based on a predetermined signal processing condition to output a signal-processed signal, and A / A that converts an analog signal into a digital signal. It is equipped with a D converter. Specifically, the signal processing unit 71 uses a filter selected from a plurality of low-pass filters having different types and characteristics with respect to the weighing signal from the weighing unit 21 to perform signal processing on only the low frequency component of the weighing signal. It is designed to pass as a signal. The low-pass filter selected by the signal processing unit 71 may be one or a combination of a plurality of low-pass filters.

  The weighing unit 72 is configured to calculate (gram conversion) the weighing value of the inspection object W based on the signal processed signal output from the signal processing unit 71. Further, in the weighing unit 72, after the carry-in sensor 4 detects that the inspected object W is carried into the weighing conveyor 32, the inspected object W is completely transferred to the weighing conveyor 32 and further output from the weighing section 21. After the reference time Tk required for the weighing signal to stabilize is measured, the object to be inspected W is weighed before being discharged from the weighing conveyor 32, and the weighing unit 21 outputs the weighing signal to be inspected. The weight value of the object W is calculated. The individual weights calculated by the weighing unit 72 are stored in the storage unit 73 as calculation data.

  In the weighing unit 72, weighing parameters relating to weighing are selected based on inspection conditions such as the measurement range, measurement capability, and inspection accuracy in accordance with the type (especially size) of the inspection object W. According to the type of the inspection object W, for example, the measurement range is selected from 6 g to 600 g, and the measurement capacity is selected at a maximum of 150 pieces / min.

  In this case, the reference time Tk for each inspected object W is set to a minimum of 400 msec, and the reference time Tk may be 400 msec or more, but the size of the inspected object W and the processing capacity of the line , Production and other conditions.

Let me remember.

  The storage unit 73 stores the transport speed and the LPF (Low Pass Filter) characteristic of the condition parameter corresponding to each product type number assigned to each product of the inspection object W. The storage unit 73 also stores, as inspection parameters, upper and lower reference values as a non-defective product range for determining the quality of the inspection object W.

  Here, the transport speed is the speed of the transport unit 3 that transports the inspection object W, the LPF characteristic indicates what kind of characteristics the low-pass filter has, and the non-defective range is determined to be non-defective It is a range of the measured value of the inspection object W to be inspected.

  The stored information is stored in advance by a setting operation from the setting unit 11 or a connection with an external device. The storage unit 73 is configured to store various data such as a measured value, a quality determination result, statistical data, and setting information from the setting unit 11 via the control unit 74.

  The control unit 74 controls the weighing conveyor 32 by reading out a predetermined transport condition and a predetermined signal processing condition from the storage unit 73 according to the type of the inspection object W.

  Further, the control unit 74 controls the transport unit 3 and the quality determination unit 76 by sequentially switching the condition parameters and the inspection parameters corresponding to the plurality of product types stored in the storage unit 73. Further, the control unit 74 drives and controls the rotation speed (rpm) of a motor (not shown) to control the transport speed of the inspection object W by the transport unit 3.

  The quality determination unit 76 is composed of a determination circuit and the like, and is configured to determine and output a quality determination result based on the comparison between the measurement value calculated by the measurement unit 72 and the quality determination reference value.

  Specifically, when the acceptability determination unit 76 receives the measured value of the inspection object W output from the measurement unit 72, it reads the upper limit value and the lower limit value stored in advance in the storage unit 73 and calculates the calculated inspection object. The measured value of the object W is compared with the upper limit value and the lower limit value, respectively, and it is determined whether or not the measured value of the inspection object W is within the allowable range determined by the upper limit value and the lower limit value. There is.

  The determination result determined by the quality determination unit 76 is output to the display unit 10 and displayed as a good product or a defective product. In addition, the determination result is output to the sorting unit 5 connected to the subsequent stage of the article inspection device 1 so that the inspection object W is sorted as a good product or a defective product. Further, this determination result is output to the storage unit 73, and the determination result for each inspection object W is stored.

  As shown in FIG. 1, the display unit 10 is provided on the upper end of the apparatus body 2 on the side of the transport unit 3 and is configured by a touch panel. The display unit 10 is configured to display the operating state of the article inspection device 1, the measured value of the inspection object W, the quality determination result, the inspection parameter, and the statistical data. Further, the display unit 10 is adapted to display an indication regarding the setting of the inspection parameter. The setting unit 11 may be integrated with the display unit 10 and all setting operations may be input from the display unit 10 by touch operation. A display example of the display unit 10 will be described later.

  The sorting unit 5 is connected to the subsequent stage of the article inspection device 1 and includes a sorting mechanism unit 5a and a conveyor belt 5b. The sorting mechanism portion 5a is configured by a flipper type (arm type) mechanism.

  The sorting mechanism unit 5a, while the inspection object W conveyed from the upstream weighing conveyor 32 is conveyed in the direction of the arrow B by the conveyance belt 5b, the inspection object W determined as a defective product is placed on the conveyance belt 5b. It is discharged from the side to the side, and is sorted by distinguishing it from the non-defective inspection object W. The sorting mechanism section 5a may be a sorting mechanism such as an extrusion type, a dropout type, and an air jet type as long as it can sort good products and defective products.

  The conveyor belt 5b is composed of a roller 5c and a roller (not shown) arranged so as to face the roller 5c, and an endless conveyor belt wound around these rollers. The inspection object W is conveyed downstream at a predetermined speed.

  As shown in FIG. 3, the operation determination table is stored in the storage unit 73. This operation determination table defines an operation related to the summation of statistical data when a predetermined trigger condition is satisfied. Specifically, in the operation determination table, whether or not to add newly generated statistical data to already generated statistical data is determined for each of a plurality of trigger conditions. In addition, the action defined by the action determination table includes information on whether to display a dialog screen for prompting the operator to confirm whether or not to add the statistical data.

  The operation determination table defines, for each of a plurality of trigger conditions, a case where statistical data is added up, a case where statistical data is not added up, and a decision dialog screen to be described later is displayed. The decision dialog screen is a dialog screen for prompting the operator to confirm whether or not to add the statistical data.

  Further, the operation defined by the operation determination table includes saving the statistical data already generated for a predetermined period when the statistical data is not added. That is, in some of the trigger conditions of this operation determination table, it is stipulated that the statistical data is not summed and the already generated statistical data is stored for a predetermined period. The contents of the operation determination table can be set and changed by the setting operation from the setting unit 11.

  The operation determination table of FIG. 3 defines a plurality of trigger conditions identified by the flag numbers 1 to 89 and an operation related to the summation of statistical data when the trigger conditions are satisfied.

  The flag number 0 has a trigger condition that the operation of starting the device is performed and the operation is started (start of inspection). When the trigger condition is satisfied, the determination dialog is displayed on the display unit 10. On the decision dialog screen, the operator decides whether or not to add the statistical data.

  Further, the flag number 1 has a trigger condition that the device is temporarily stopped and the operation is restarted. When this trigger condition is satisfied, the statistical data is summed up. An approval dialog screen may be displayed to allow the operator to confirm that the statistics will be continued when the operation is restarted. By doing this, if the operator approves the statistics continuously on the approval dialog screen, the operation is restarted and the statistical data is added. If the operator does not approve, the operation cannot be restarted or the statistical data is added. Can be prevented from being executed, and an erroneous operation related to the summation of statistical data due to a setting error in the contents of the operation determination table can be prevented.

  The flag number 2 has a trigger condition that the product type switching operation is performed and the operation is started. When the trigger condition is satisfied, the determination dialog is displayed on the display unit 10 as in the case of the flag number 0, and the operator is allowed to determine whether to add the statistical data.

  The flag number 3 has a trigger condition that the lot switching operation is performed. When this trigger condition is satisfied, statistics are not continued for new inspection results, that is, statistical data is not summed. In addition, the statistical data that has already been generated is retained for a predetermined period without being immediately deleted.

  The flag number 88 has a trigger condition that a printing operation is performed. When this trigger condition is satisfied, the statistical data is not summed. Moreover, the statistical data already generated is immediately deleted.

  The flag number 89 has a trigger condition that the statistics erasing operation has been performed. When this trigger condition is satisfied, the statistical data is not added like the flag number 88, and the already generated statistical data is immediately deleted. The control unit 74 executes the operation related to the summation of the statistical data according to the operation determination table.

  FIG. 4 is a flowchart showing a statistical data-related operation that is an operation related to the summation of statistical data. This statistical data-related operation is repeatedly executed at a predetermined short cycle during system startup.

  In FIG. 4, the control unit 74 first determines whether or not the trigger condition is satisfied (step S1). Here, the control unit 74 determines whether or not all the trigger conditions are satisfied. If there is a satisfied trigger condition, the process proceeds to step S2, and if there is no satisfied trigger condition, the current operation ends. To do.

  In step S2, the control unit 74 refers to the operation determination table and determines an operation related to the summation of statistical data.

  Next, the control unit 74 proceeds to step S3, and determines whether or not the operation determination table is set to add the statistical data. If the determination in step S3 is NO, the control unit 74 proceeds to step S7 and determines whether or not the operation determination table specifies that statistical data should not be added together. When the determination in step S7 is NO, the control unit 74 proceeds to step S11.

  If the determination in step S3 is YES (statistical data is added), the control unit 74 displays an approval dialog screen on the display unit 10 (step S4) and determines whether or not the operator has approved (step S5). When the approval is obtained in step S5, the control unit 74 adds up the statistical data (step S6), and ends the operation of this time. On the other hand, if there is no approval in step S5, the control unit 74 does not add up the statistical data (step S10) and ends the current operation.

  If the determination in step S7 is YES (statistical data is not added), the control unit 74 displays an approval dialog screen on the display unit 10 (step S8) and determines whether or not the operator has approved (step S9). When the approval is obtained in step S9, the control unit 74 does not add up the statistical data (step S10) and ends the operation of this time. On the other hand, if there is no approval in step S9, the control unit 74 adds up the statistical data (step S13), and ends the operation of this time.

  In step S11, the control unit 74 causes the display unit 10 to display the determination dialog screen. On this decision dialog screen, the operator decides whether or not to add the statistical data.

  Next, the control unit 74 determines whether or not the operator has decided to add the statistical data (step S12). When the summation of the statistical data is determined in step S12, the control unit 74 sums the statistical data (step S13) and ends the operation of this time. On the other hand, if it is determined in step S12 that the statistical data is not added up, the statistical data is not added up (step S14) and the operation of this time is ended.

  In the flow described above, an example has been described in which the approval dialog screen for allowing the operator to confirm that the statistics are continued is displayed, but the approval dialog screen may not be displayed. In the example in which the approval dialog screen is not displayed, if the determination in step S3 is YES, the process proceeds to step S6 to add the statistical data, and if the determination in step S7 is YES (the statistical data is not added), the process proceeds to step S10. The operation ends without summing up the statistical data with. That is, in an example in which the approval dialog screen is not displayed, steps S4 and S5 and steps S8 and S9 are omitted.
