A function for detecting the posture (inclination information) or the like can be executed at a predetermined timing.

<1.1.3. Hardware configuration of weight sorter>
FIG. 3 is a front view showing an example of the configuration of the weight sorter 5. The bag BG filled with the article X to be packaged in the vertical bag making and packaging machine 3 is conveyed to the seal checker 4 to check the sealing condition, and then conveyed to the weight sorter 5.

  For example, the weight sorter 5 measures the weight of a product (measurement object 55) carried from a previous process such as a bagging process, and distributes the product based on the measurement result. As shown in FIG. 3, the weight sorter 5 mainly includes a take-in device 51, a weighing device 52 (weighing machine), and a sorting device 56.

  As shown in FIG. 3, the capture device 51 mainly includes a capture conveyor 511 and a gyro sensor 593a (second inclination detection unit). The take-in device 51 conveys the weighing object 55 to the downstream weighing device 52 side when viewed from the conveyance direction AR3 of the weighing object 55.

  The take-in conveyor 511 is a transport unit disposed downstream of the seal checker 4 when viewed from the transport direction AR3. The gyro sensor 593a (second inclination detection unit) is a so-called angle sensor, similar to the gyro sensor 293 and the gyro sensor 393, and detects the inclination of the take-in conveyor 511. As shown in FIG. 1, the gyro sensor 593 a is disposed below the intake conveyor 511.

  As shown in FIG. 3, the weighing device 52 mainly includes a weighing conveyor 521, a weight sensor 591, a GPS sensor 592, and a gyro sensor 593 b, and a weighing object conveyed by the weighing conveyor 521. Weigh 55.

  The weighing conveyor 521 is a transport unit disposed between the take-in conveyor 511 and the transport conveyor 561. The weighing conveyor 521 conveys each sorting object 55 delivered from the take-in device 51 to the sorting device 56. As shown in FIG. 3, the weighing conveyor 521 is supported by the strain body 531 of the load cell unit 591 (weight sensor) via the attachment member 525.

  Therefore, the strain body 531 receives the load of the weighing conveyor 521 and the weighing object 55 conveyed on the weighing conveyor 521, and the weight sensor 591 receives a load signal corresponding to the weight of the weighing conveyor 521 and the weighing object 55. Is output.

  The GPS sensor 592 is a receiver that receives GPS signals from a plurality of GPS satellites, like the GPS sensor 292 and the GPS sensor 392. Further, the gyro sensor 593b (first inclination detection unit) is a so-called angle sensor similarly to the gyro sensor 593a, and detects the inclination of the weighing conveyor 521. As shown in FIG. 1, the GPS sensor 592 and the gyro sensor 593 b are disposed below the weighing conveyor 521.

  As shown in FIG. 3, the distribution device 56 mainly includes a transfer conveyor 561, a lever 562, and a gyro sensor 593 c (third inclination detection unit). The sorting device 56 sorts the weighing object 55 delivered from the weighing device 52 and conveyed by the conveyor 561 based on the measurement result of the weighing device 52.

  The transport conveyor 561 is a transport unit that transports the weighing target object 55 that has been delivered from the weighing device 52 along the transport direction AR3. The lever 562 is pivotable about a pivot shaft 562a that is substantially perpendicular to the transport direction AR3, and distributes the weighing object 55 transported by the transport conveyor 561.

  Similar to the gyro sensors 593a and 593b, the gyro sensor 593c (third inclination detection unit) is a so-called angle sensor and detects the inclination of the transport conveyor 561. As shown in FIG. 1, the gyro sensor 593 c is disposed below the transfer conveyor 561.

  For example, when the measurement result by the weighing device 52 falls within the non-defective range, the lever 562 is rotated so that the length direction thereof is substantially parallel to the conveyance direction AR2 and is located on the side of the conveyance conveyor 561. . As a result, the weighing object 55 is transferred to a non-defective product line (not shown) arranged on the extension of the transport direction AR3.

  On the other hand, when the measurement result by the weighing device 52 is out of the non-defective range, the lever 562 is rotated so as to block the conveyance of the selection target 55. As a result, the selection object 55 that has reached the lever 562 moves along the lever 562 and is delivered to a defective product line (not shown) provided on the side of the conveyor 561.

<1.2. Functional configuration of weighing packaging system>
FIG. 4 is a block diagram showing an example of the functional configuration of the combination weighing machine 2 and the vertical bag making and packaging machine 3. FIG. 5 is a diagram illustrating an example of the data structure of the regional parameter storage unit 271. FIG. 6 is a block diagram illustrating an example of a functional configuration of the weight sorter 5. Below, the function structure of each control unit 20, 30, 50 is demonstrated in order of the weighing machine control unit 20, the packaging machine control unit 30, and the weight sorter control unit 50.

<1.2.1. Functional configuration of combination weighing machine>
As shown in FIG. 4, the CPU 20b mainly realizes a weight detection function, a position detection function, an attitude determination function, and a region parameter extraction function. In addition, a storage area for the regional parameter storage unit 271 is secured on the memory 20a.

  Here, the regional parameter storage unit 271 is a table (two-dimensional table) that stores regional parameters determined by the installation location of the combination weighing machine 2 and position information in association with each other. As shown in FIG. 5, the regional parameter storage unit 271 mainly includes an “identification ID”, “latitude upper limit”, “latitude lower limit”, “longitude upper limit”, and “longitude lower limit” used as position information, Each field (column) includes “weight unit information” and “language information” used as regional parameters.

  The “identification ID” field stores a value for uniquely identifying each record (each row) included in the regional parameter storage unit 271. In each field of “latitude upper limit”, “latitude lower limit”, “longitude upper limit”, and “longitude lower limit”, a latitude value and a longitude value used for the extraction process of the regional parameters are stored.

  In the “weight unit information” field, information on the weight unit to be used is stored. For example, in an area designated by “identification ID” = “10020”, “gram” is used as a weight unit. The “language information” field stores information about the language used. For example, in an area designated by “identification ID” = “10021”, “English” is used as the language (official language).

  The weight detection unit 281 detects the weight of the measurement object based on the load signal output from the weight sensor 291. In the present embodiment, the weight detection unit 281 directly calculates the weight of the weight unit specified by the weight unit information from the load signal for the weight unit information extracted as the regional parameter. That is, the weight detection unit 281 does not employ a calculation method of calculating the weight of the weighing object in a different weight unit different from the installation location, and then converting it to a weight unit corresponding to the installation location. No rounding error occurs. Therefore, the weight detection unit 281 can suppress a decrease in weight detection accuracy due to the calculation.

  The position detection unit 282 detects position information of an installation location of the combination weighing machine 2 based on a plurality of GPS signals received by the GPS sensor 292. The extraction unit 284 extracts a regional parameter corresponding to the installation location from the regional parameter storage unit 271 based on the position information detected by the position detection unit 282.

  For example, regarding the detected location information (latitude value and longitude value) of the combination weighing machine 2, the latitude value of the installation location is not less than “latitude lower limit” in the regional parameter storage unit 271 and smaller than “latitude first chord”; When the longitude value of the installation location is not less than “longitude lower limit” and smaller than “longitude first chord” in the regional parameter storage unit 271, a corresponding record is extracted from the regional parameter storage unit 271.

  The posture determination unit 283 determines the posture of the combination weighing machine 2 based on the tilt information detected by the gyro sensor 293. For example, when it is determined that the tilt information detected by the gyro sensor 293 is within the allowable range, the posture determination unit 283 has the tilt of the combination weighing machine 2 within the normal range and can perform normal weighing processing. Judge. On the other hand, when the tilt information is out of the allowable range, the posture determination unit 283 determines that the combination weighing machine 2 is not correctly installed and normal weighing processing cannot be performed.

  Here, the tilt information of the vertical bag making and packaging machine 3 is outside the allowable range, while the tilt information of the combination weighing machine 2 stacked above the vertical bag making and packaging machine 3 is within the allowable range. Consider the case. In this case, the combination weighing machine 2 is not inclined with respect to the inclination reference plane (for example, the floor surface) of the vertical bag making and packaging machine 3, but is inclined with respect to the vertical bag making and packaging machine 3. The combination weighing machine 2 is not correctly arranged with respect to the vertical bag making and packaging machine 3. As a result, the measurement accuracy by the combination weighing machine 2 may be reduced.

  Therefore, in the present embodiment, the posture determination unit 283 includes each of the gyro sensor 293 (first inclination detection unit) of the combination weighing machine 2 and the gyro sensor 393 (second inclination detection unit) of the vertical bag making and packaging machine 3. The posture of the combination weighing machine 2 is determined based on the inclination information detected by the above. Thereby, the posture of the combination weighing machine 2 stacked above the vertical bag making and packaging machine 3 can be accurately grasped. Therefore, the combination weighing machine 2 can be satisfactorily installed above the vertical bag making and packaging machine 3, and the weighing accuracy of the weighing object by the combination weighing machine 2 can be improved.

  The display unit 294 is configured by a liquid crystal display, for example, and can display characters, images, and the like on the screen. Therefore, the display unit 294 can display information (such as the name and weight of the measurement object) regarding the measurement object whose weight has been detected based on the regional parameters determined by the extraction unit 284.

  Further, the display unit 294 can display the weight of the measurement object in the weight unit designated by the weight unit information for the weight unit information extracted as the regional parameters. In this case, the display unit 294 can output the weight of the weighing object in units of weight according to the installation location. Therefore, the user does not need to switch the weight unit regardless of the installation location, and the work burden on the user is reduced.

  Further, the display unit 294 can display information related to the measurement object in the language specified by the language information for the language information extracted as the regional parameters. In this case, the display unit 294 can display characters and the like in a language corresponding to the installation location (that is, a language corresponding to the user of the installation location). Therefore, it is possible to prevent a decrease in work efficiency due to language regardless of the installation location.

  The display unit 294 can output the determination result of the posture determination unit 283. Thereby, the user can grasp | ascertain the attitude | position of the combination weighing machine 2 easily. Therefore, the combination weighing machine 2 can be installed satisfactorily, and the weighing accuracy of the weighing object can be improved. As described above, the display unit 294 is used as an output unit for information on the measurement object.

  In addition, the display unit 294 has a function as a “touch panel” that can specify a position on the screen by touching the screen with a finger or a dedicated pen. Therefore, the user can cause the combination weighing machine 2 to execute a predetermined operation by giving an instruction using the “touch panel” function of the display unit 294 based on the content displayed on the display unit 294. . Thus, the display unit 294 is also used as an input unit.

  The printing unit 295 records characters, images, and the like on recording paper. Similarly to the display unit 294, the printing unit 295 can record information on the weighing object whose weight has been detected on a recording sheet based on the regional parameters determined by the extraction unit 284. As described above, the printing unit 295 can be used as an output unit for information on the measurement object, similarly to the display unit 294.
