It is thrown into. The belt conveyor supplies the non-dried foods put on the belt conveyor to the plurality of feeding units 9 in small amounts according to a command from a control unit (not shown). Each input section 9 is located on the weighing hopper 8 and supplies pasta to each weighing hopper 8.

  In this combination scale 4, pasta is weighed by each of a plurality of weighing hoppers 8, a combination of weighing hoppers 8 in which the total weight of the weighed pasta is a predetermined weight is selected, and the pasta is discharged from the selected weighing hopper 8. To do. The pasta is supplied to the weighing hopper 8 from which the pasta has been discharged through a feeding unit 9 by a belt conveyor built in the supply unit 10.

  The chute 6 is arranged at the lower part of the combination weigher 4 and collects the pasta discharged from each weighing hopper 8. The chute 6 is arranged at the lower part of the collective chute 12 and adjusts the timing for discharging the pasta. The funnel 16 is disposed below the timing hopper 14 and fills a predetermined container with pasta.

  2A and 2B are diagrams showing the configuration of the weighing hopper 8 of the combination weigher 4 according to the embodiment, where FIG. 2A is a front view and FIG. 2B is a top view. The weighing hopper 8 has a structure in which two gates 8b are provided in a lower portion of a rectangular tube-shaped main body portion 8a that is open at the top and bottom. Here, the gate 8b of the weighing hopper 8 is opened and closed by a command from a control unit (not shown), and when the gate 8b is closed, the weight of the pasta is measured by a measurement unit (not shown) such as a load cell. Further, the pasta in the weighing hopper 8 is discharged when it is in the open state.

  3A and 3B are diagrams showing the configuration of the collective chute 12 according to the embodiment, in which FIG. 3A is a front view and FIG. 3B is a top view. As shown in FIG. 3 (b), the collecting chute 12 has a charging port 12a that is a rectangular opening into which pasta discharged from the weighing hopper 8 is charged, and the distance between the inner walls on the short side, And each of the distance of the inner wall surfaces of a long side has a shape which becomes narrow as it goes to the discharge port 12b which is a rectangular opening. Around the outer wall surface of the collective chute 12, a jacket-type heating unit 18 (heat insulation device) that heats by circulating warm water or steam is wound.

  The heating unit 18 is provided with a flow path for circulating heated hot water or steam, and the temperature of the inner wall surface of the collecting chute 12 measured by a temperature sensor (not shown) is within a predetermined range. The outer wall surface of the collective chute 12 is heated by controlling the temperature so as to be (50 to 60 degrees).

  4A and 4B are diagrams showing the configuration of the timing hopper 14 according to the embodiment, where FIG. 4A is a front view and FIG. 4B is a top view. The timing hopper 14 has a structure in which a gate portion 25 having two gates 24 is provided at a lower portion of a rectangular tube-shaped main body portion 22 having upper and lower openings. Here, the gate 24 opens and closes according to a command from the control unit, temporarily stores the pasta discharged from the collective chute 12 during the closed state, and discharges the stored pasta when the open state is reached.

  A jacket-type heating unit 26 similar to the heating unit 18 is wound around the outer wall surface of the main body 22 of the timing hopper 14. A jacket-type heating unit 27 similar to the heating unit 18 is attached to the gate unit 25 of the timing hopper 14. The heating units 26 and 27 are connected to the main body 22 and the gate so that the temperature of the inner wall surface of the main body 22 and the gate 24 measured by a temperature sensor (not shown) is in a predetermined range (50 to 60 degrees). The outer wall surface of the part 25 is heated.

  5A and 5B are diagrams showing the configuration of the funnel 16 according to the embodiment, where FIG. 5A is a front view, and FIG. 5B is a top view. The funnel 16 has an input port 16a for inputting pasta discharged from the timing hopper 14 and an output port 16b for discharging pasta. Here, the discharge port 16b is formed in a size corresponding to a container filled with pasta. A jacket-type heating unit 30 similar to the heating unit 18 is wound around the outer wall surface of the funnel 16. The heating unit 30 heats the outer wall surface of the funnel 16 so that the temperature of the inner wall surface of the funnel 16 measured by a temperature sensor (not shown) becomes a predetermined range of temperature (50 to 60 degrees). Below the funnel 16, a container transport unit (not shown) such as a belt conveyor for continuously transporting containers filled with pasta is disposed.

  When filling the container with pasta by the filling device 2 according to this embodiment, when the pasta introduced by the operator from the insertion port 9 of the combination scale 4 is supplied to each weighing hopper 8, a plurality of weighing hoppers 8 are provided. , The pasta is weighed, the combination of the weighing hopper 8 in which the weighed pasta has a predetermined weight is selected, and the pasta is discharged from the selected weighing hopper 8.

  The pasta discharged from the weighing hopper 8 is collected in the collecting chute 12 and filled into the container via the timing hopper 14 and the funnel 16. In this case, the outer wall surfaces of the collecting chute 12, the timing hopper 14 and the funnel 16 are heated by the heating units 18, 26, 27 and 30, and the inner wall surfaces of the collecting chute 12, the timing hopper 14 and the funnel 16 are within a predetermined range. Since it is kept at the temperature, the sauce of the pasta can be prevented from being cooled and solidified. Accordingly, since the pasta falls smoothly in the collecting chute 12, the timing hopper 14 and the funnel 16, it is possible to prevent the pasta and the source from adhering to the inner wall surfaces of the collecting chute 12, the timing hopper 14 and the funnel 16. .

  According to the filling device 2 according to this embodiment, it is possible to prevent pasta from adhering to the inner wall surfaces of the weighing hopper 8, the collecting chute 12, the timing hopper 14, and the funnel 16, and the non-dried food with high accuracy. Can be weighed and filled into containers.

  In the filling device 2 according to the above-described embodiment, the jacket type heating units 18, 26, 27, and 30 are used. However, the heater type heating unit including a rubber heater or a ceramic heater is not limited thereto. It may be used.

  Next, the accuracy of metering and filling when the filling device 2 of the present invention is operated will be described. In the filling device 2, the container was filled with the pasta 1500 times in 30 minutes. The target amount of pasta to be filled in one container was set to 14 g. For pasta, macaroni with carbonara sauce was used. Table 1 shows the standard deviation σ (g) of the filling amount into the container when 30 minutes have elapsed from the start of operation of the filling device 2.

  Next, the weighing and filling accuracy when the conventional apparatus is operated will be described. The conventional apparatus measures pasta with a plurality of weighing hoppers, selects a combination of hoppers in which the total weight of the weighed pasta is a predetermined weight, discharges the pasta, collects the discharged pasta through a collecting chute, and packaging apparatus It is a weighing device to supply to. In the conventional apparatus, the heating unit 30 according to the present invention is not wound around the outer wall surface of the collective chute.

  As in the above-described filling device 2, the conventional device supplies pasta to the packaging device 1500 times in 30 minutes, and sets the target amount of pasta to be supplied at one time to 14 g. Table 2 shows the standard deviation σ (g) of the supply amount to the packaging device when 30 minutes have elapsed since the start of operation of the conventional device.

  It has been found that the filling device 2 of the present invention has extremely excellent metering and filling accuracy compared to the conventional device.
