[Configuration of weighing device]

  As shown in FIG. 1, the weighing device 1 includes a transport unit 2, a detection unit 3, a weighing unit 4, a sorting unit 5, a control unit 6, an input unit 7, a display unit 8, and a notification. A lamp 9 and a speaker 10 are provided. The weighing device 1 is installed in a production line for an article G such as food, for example. The weighing device 1 measures the mass of the article G while conveying the article G along the conveyance direction A, and distributes the articles G according to the measurement result of the article G.

  The transport unit 2 transports the article G along the transport direction A. The transport unit 2 includes transport conveyors 21, 22, and 23 arranged in parallel along the transport direction A. The detection unit 3 is, for example, a photoelectric sensor, and is provided at the upstream end of the central conveyor 22. The detection unit 3 detects the article G conveyed by the conveyance unit 2.

  The weighing unit 4 is provided on a central conveyor 22. The weighing unit 4 measures the mass of the article G conveyed by the conveyor 22 (that is, performs a mass inspection). The weighing unit 4 is a dynamic weighing (first weighing) that measures the mass of the article G without stopping the conveyance of the article G, and a stationary weighing (second weighing) that stops the conveyance of the article G and measures the mass of the article G. Weighing) can be carried out. As an example, the weighing unit 4 includes a gantry 41, a weighing cell 42, and an AFV (Anti Floor Vibration) cell 43.

  The weighing cell 42 measures the mass of the article G located on the transport conveyor 22. The weighing cell 42 includes a strain body 42a, a movable rigid body portion 42b, and a fixed rigid body portion 42c. The strain body 42a is connected to each of the movable rigid body portion 42b and the fixed rigid body portion 42c. The movable rigid part 42b supports the conveyor 22. The fixed rigid portion 42 c is fixed to the gantry 41. The weighing cell 42 outputs a weighing signal corresponding to the mass of the article G to the first filter unit (not shown) and the control unit 6. The first filter unit performs filtering processing on the weighing signal output from the weighing cell 42 to remove noise from the weighing signal, and outputs the filtered weighing signal to the control unit 6.

  The AFV cell 43 detects disturbance vibrations of the weighing unit 4 including the weighing cell 42 (vibrations transmitted from the floor F to the weighing unit 4, vibrations of the conveyor 22, etc.). The AFV cell 43 is connected to the fixed rigid part 42c. The AFV cell 43 outputs a vibration signal corresponding to disturbance vibration to a second filter unit (not shown). The second filter unit performs filtering processing on the vibration signal output from the AFV cell 43 to remove noise from the vibration signal, and outputs the vibration signal after the filtering processing to the control unit 6. In the control unit 6, the influence of disturbance vibration and the like is determined from the measurement signal based on the measurement signal output from the measurement cell 42, the measurement signal output from the first filter unit, and the vibration signal output from the second filter unit.

The allocating unit 5 has a pusher 5 a that can advance and retract in the horizontal direction intersecting the transport direction A. The pusher 5a is driven by, for example, an air cylinder (not shown). The sorting unit 5 sorts the articles G conveyed by the conveyor 23 by advancing and retracting the pusher 5a according to the weighing result of the articles G by the weighing unit 4. As an example, when the mass of the article G measured by the weighing unit 4 is out of a predetermined range, the sorting unit 5 pushes the article G conveyed by the conveyance conveyor 23 in the horizontal direction intersecting the conveyance direction A. Thus, pusher 5a is advanced. Thereby, the article G is discharged from the transport conveyor 23. On the other hand, when the mass of the article G weighed by the weighing unit 4 is within a predetermined range, the sorting unit 5 retracts the pusher 5a. Thereby, the article G is transported by the transport conveyor 23.

  The control unit 6 controls the operation of each unit in the weighing device 1. The control unit 6 uses the detection of the article G by the detection unit 3 as a trigger to control the timing of the mass inspection of the weighing unit 4 and the timing of the distribution operation of the distribution unit 5, and based on the inspection result of the measurement unit 4. Thus, the sorting operation of the sorting unit 5 is controlled. The control unit 6 is configured as a computer device including a processor, a memory, a storage, a communication device, and the like. In the control unit 6, the processor executes predetermined software (program) read into the memory or the like, and controls reading and writing of data in the memory and storage, and communication by the communication device, thereby controlling the control unit 6. Function is realized.

The input unit 7 receives various inputs by the operator, such as input of operating conditions by the operator. The input unit 7 includes a jog dial 7a and a plurality of input keys 7b. A backlight (not shown) is provided on the back side of the jog dial 7a and the plurality of input keys 7b. The input unit 7 emits light according to the operation status of the weighing device 1 and the like. The display unit 8 displays various information such as the mass of the article G weighed by the weighing unit 4. The display unit 8 may be configured as a touch panel, for example, and may have a function as an input unit. The notification lamp 9 emits light according to the operation status of the weighing device 1 and the like. The notification lamp 9 emits red, yellow and green light, for example. The speaker 10 emits a sound according to the operation status of the weighing device 1 and the like. The input unit 7, the display unit 8, and the notification lamp 9 function as a notification unit that emits light according to the operation status of the weighing device 1. The speaker 10 functions as a notification unit that emits a sound in accordance with the operation status of the weighing device 1 and the like.
