  Further, in order to prevent the fruits and vegetables 16 from accumulating in the connection portion 38 by reducing the transport speed of the horizontal transport conveyor 20 and the intermediate transport conveyor 26 instead of shortening the time for replacing the container 14, the container 14 It is possible to maintain a stable weighing accuracy by maintaining the time for replacement. In addition, the time which replaces | exchanges the container 14 is about 2 to 3 second at present. Moreover, since the conveyance speed of the horizontal conveyance conveyor 20 and the intermediate conveyance conveyor 26 is lowered only when the containers 14 are replaced, the article boxing facility 10 does not have insufficient capacity.

  When the containers 14 are replaced, the horizontal conveyor 20 conveys the fruits and vegetables 16 at the second horizontal conveyance speed V12, and the intermediate conveyance conveyor 26 has the second intermediate conveyance speed and the second horizontal conveyance speed. The fruits and vegetables 16 are transported at a speed V22 lower than the transport speed V12, and the transport speed V3 (a) of the main transfer conveyor 28 (a) and the transport speed V3 (b) of the sub-transfer conveyor 28 (b) are zero. That is, when the container 14 is replaced, the conveyance speed is reduced in three stages as it goes downstream from the lateral conveyance conveyor 20 to the intermediate conveyance conveyor 26, the main transfer conveyor 28 (a), and the sub transfer conveyor 28 (b). It will be done. Therefore, when the containers 14 are replaced, the fruits and vegetables 16 can be arranged as evenly as possible on the horizontal transfer conveyor 20, the intermediate transfer conveyor 26, the main transfer conveyor 28 (a), and the sub transfer conveyor 28 (b). It becomes possible. In addition, another intermediate transfer conveyor is provided between the horizontal transfer conveyor 20 and the intermediate transfer conveyor 26, or between the intermediate transfer conveyor 26 and the main transfer conveyor 28 (a) and the sub transfer conveyor 28 (b). When the container 14 is replaced, the conveyance speed may be decreased in four or more stages as it goes downstream from the horizontal conveyance conveyor 20.

  Here, the main transfer conveyor 28 (a), the sub transfer conveyor 28 (b), the main dropping conveyor 24 (a), and the sub dropping conveyor 24 (b) were stopped to stop the dropping of the fruits and vegetables 16 into the container 14. At the same time, it is not limited to transporting the fruits and vegetables 16 to the lateral transport conveyor 20 at the second lateral transport speed V12 and transporting the fruits and vegetables 16 to the intermediate transport conveyor 26 at the second intermediate transport speed V22. For example, when the main transfer conveyor 28 (a), the sub-transfer conveyor 28 (b), the main dropping conveyor 24 (a), and the sub-dropping conveyor 24 (b) are stopped to stop dropping the fruits and vegetables 16 into the container 14 After a certain period of time has elapsed, the vegetables and fruits 16 are conveyed to the intermediate conveyance conveyor 26 at the second intermediate conveyance speed V22, and after a certain period of time, the fruits and vegetables 16 are conveyed to the horizontal conveyance conveyor 20 at the second horizontal conveyance speed V12. It may be conveyed. When the main transfer conveyor 28 (a), the sub-transfer conveyor 28 (b), the main dropping conveyor 24 (a) and the sub-dropping conveyor 24 (b) are stopped to stop dropping the fruits and vegetables 16 into the container 14. After a certain period of time has elapsed, the vegetables and fruits 16 are conveyed to the horizontal conveyor 20 at the second lateral conveying speed V12, and after a certain period of time, the fruits and vegetables 16 are conveyed to the intermediate conveyor 26 at the second intermediate conveying speed V22. It may be conveyed. When the container 14 is replaced, if the horizontal conveyance conveyor 20 that conveys at a speed higher than the conveyance speed of the intermediate conveyance conveyor 26 is decelerated first, the fruits and vegetables 16 are transferred to the horizontal conveyance conveyor 20, the intermediate conveyance conveyor 26, and the main transfer conveyor. 28 (a) and the auxiliary transfer conveyor 28 (b) can be arranged as evenly as possible.
