That is, for example, a plurality of control boards may be provided according to various controls, and the control device 3 may be configured by the plurality of control boards. The control device 3 is not necessarily provided in the combination weigher. For example, the control device 3 may be controlled by the external control device 3 by connecting a personal computer or the like as the external control device 3.

  Furthermore, the storage unit 32 stores information on each peripheral device that can be connected to the combination weigher. FIG. 5 is a diagram showing a storage table related to peripheral devices stored in the combination weigher shown in FIG. As shown in FIG. 5, in the storage unit 32, for each peripheral device, the position relative to the combination weigher, the interlock condition, and the connection locations on the combination weigher side and the peripheral device side corresponding to the interlock condition (for example, The connection terminal numbers as shown in FIG. 5 are stored.

The position coordinates of each peripheral device based on the coordinate system on the display screen may be stored.

  Here, the interlock condition of each peripheral device will be described. The interlock condition means a condition of the combination weigher or the peripheral device for the corresponding peripheral device to perform a predetermined operation or stop by the relationship between the combination weigher and the peripheral device or the relationship between the peripheral devices. For example, the combination weigher of this embodiment, a hopper (weighing hopper 1 and the supply hopper 4) biting, when all discharge operation or the reject operation of the conveyor 16 occurs, capable of stopping the supply conveyor 51 It is configured as follows. Therefore, the interlock condition for the supply conveyor 51 can selectively employ at least one of hopper biting, full discharge operation, and transfer conveyor 16 rejection operation. Note that the full discharge operation is a process of opening the gates of all hoppers to discharge the objects to be weighed in all hoppers, and when there is no discharge combination, when cleaning in the hopper, This is the process performed during zero adjustment. Moreover, the reject operation of conveyor 16, when the weight value in the check conveyor 53 (conveyor 16) is not within a predetermined combination weight range, to reverse the conveying direction of the conveyor 16 (the packaging machine on the side opposite to the Means to drive in the direction and discharge as a measurement error).

It is configured to be able to switch the independent mode for independent operation regardless of the state of each peripheral device. As the predetermined operation, for example, for the first collective hopper 54, the subsequent peripheral devices (secondary conveyor 55, packaging machine 57, etc.) are stopped. In addition, regarding the secondary conveyor 55 and the second collective hopper 56, the subsequent packaging machine 57 does not output a discharge request signal. Further, for the packaging machine 57, the combination weigher has received the discharge command signal from the packaging machine 57.

  As described above, as the interlock condition for the first collective hopper 54, the secondary conveyor 55, and the second collective hopper 56, either alone or interlocking can be selectively adopted. Further, the combination weigher is configured to be able to employ a plurality of stop conditions according to the specifications of the packaging machine 57. In the present embodiment, for example, a normal specification mode common to the manufacturer of the packaging machine 57 and each company specification mode corresponding to each manufacturer can be selected. In this case, as the interlocking condition of the combination weigher for the packaging machine 57, for example, any one of the normal specification mode, the A company specification mode, and the B company specification mode can be selectively adopted.

  Further, the combination weigher is configured to be able to switch whether or not to use the article detection sensor 52 and the check conveyor 53. When the article detection sensor 52 is in the ON state, when the article detection sensor 52 detects that the amount of the object to be weighed on the top plate 14 exceeds a predetermined value, the interlock condition selection state for the supply conveyor 51 is set. Regardless, an interlock signal is sent to the supply conveyor 51. That is, the interlock condition of the supply conveyor 51 changes according to the ON / OFF state of the article detection sensor 52.

  The storage unit 32 stores a plurality of interlock conditions as described above for each peripheral device. Furthermore, in the storage unit 32, a device selection screen 321 for selecting a plurality of peripheral devices that can be connected to the combination weigher, and an arrangement screen 322 that can selectively display schematic diagrams of the plurality of peripheral devices are selected.

Ri, functions as a storage means. Each display screen may be stored independently or may be stored in association with each other. For example, regarding an interlock test screen 327 described later, an arrangement screen 322 and a predetermined command execution button are stored in the storage unit 32, and when the interlock test screen 327 is displayed, the arrangement screen 322 is displayed from the storage unit 32. The interlock test screen 327 may be displayed by reading the command execution button and displaying the command execution button on the arrangement screen 322. In addition, the schematic diagram is not particularly limited as long as the positional relationship with the semi-automatic combination weigher is displayed on each display screen to an extent that can be understood at first glance. For example, a schematic diagram illustrating the shape of the peripheral device A block diagram with peripheral device names added is included. The schematic diagram group 320 and the screens 321 to 327 may not be stored in the storage unit 32 but may be input to the control unit 31 from the outside.

Then, the selection completion button (save button in FIG. 7) 71 on the device selection screen 321 is touch-selected. Thereby, the control unit 31 recognizes that the selection of the peripheral device has been completed. The control unit 31 determines whether or not the selection of the peripheral device is completed (step S2). When the control unit 31 determines that the selection of the peripheral device is completed, the storage unit 32 stores the selected combination of one or more peripheral devices. And the position (positional coordinates, etc.) of each peripheral device in the system constituted by the selected one or more peripheral devices is read from the storage unit 32 (step S3). The control unit 31 functions as the display control unit 31a, and displays the schematic diagram of the selected peripheral device at each position (position coordinate) on the arrangement screen 322 at the read position, thereby selecting the combination weigher and the selected scale. A layout of the system constituted by the peripheral devices is displayed on the setting display device 8 (step S4). At this time, peripheral devices not selected are not displayed on the arrangement screen 322.
