If the destinations of the goods are different, the two goods cannot be properly sorted. That is, when the arm member 94 is arranged on the main transport path 91, not only the articles on the downstream side but also the articles on the upstream side are guided to the sub-transport path 92 side by the arm member 94, and the arm member 94 is mainly used. When evacuated from the transport path 91, both articles move to the downstream side of the main transport path 91.
  • the articles must be transported at intervals so that the preceding article has completely passed through the area where the arm member 94 is arranged, and then the succeeding article has entered the area where the arm member 94 is arranged. , Subsequent articles cannot be sorted properly. Therefore, inevitably, the distance between the articles is widened, and the number of articles that can be sorted per unit time is reduced.
  • the first aspect of the present invention for solving the above problems is an article sorting device for sorting articles by switching the conveying direction of the articles in a conveyor device having a main transport path and a sub transport path intersecting the main transport path.

Since it is possible, the transport direction can be set for each section independently of the other sections. Further, since the transport direction of each section of the sorting area is switched to the transport direction of the subsequent articles in order from the upstream side in the transport direction, even if the upstream article and the downstream article are close to each other or in close contact with each other, the upstream side article is used. When the article enters the sorting area, it is properly urged in the transport direction. Therefore, the goods on the upstream side are smoothly transported in an appropriate transport direction. That is, according to this aspect, even if the articles on the upstream side and the articles on the downstream side in the transport direction are close to each other or in close contact with each other, each article can be appropriately sorted.
  • the length in the direction from the upstream side to the downstream side in the transport direction of each section is shorter than the length in the direction from the upstream side to the downstream side of the article assumed to be transported, and the preceding article leaves the section. It is preferable to switch the transport direction of each section to the transport direction of the succeeding article in order from the upstream side in the transport direction when the preceding article is separated from the section.
  • the length in the direction from the upstream side to the downstream side in the transport direction of each section is shorter than the length in the direction from the upstream side to the downstream side of the article assumed to be transported. It straddles multiple sections and passes through each section. Then, when the preceding article leaves the section or when the preceding article leaves the section, the transport direction of each section of the sorting area is set to the transport direction of the succeeding article in order from the upstream side in the transport direction. By switching, subsequent articles are transported in the appropriate transport direction. That is, the preceding article passes through each section arranged from the upstream side to the downstream side in order from the upstream side section.
  • the succeeding article invades the section through which the preceding article has passed, but the transport direction (the urging direction) of the section in which the succeeding article invades is changed promptly and in a timely manner. Therefore, the subsequent articles are appropriately transported in the transport direction.
  • the transport direction of the article is on the side of the secondary transport path intersecting the main transport path, the downstream side of the article is in the secondary transport path, and the upstream side of the article remains in the article sorting device. , It is preferable to switch the transport direction of the article sorting device to the straight-ahead direction side.
  • the transport direction of the preceding article is on the sub-transport path side where the main transport path intersects, the downstream side of the article is in the sub-transport path, and the upstream side of the article is in the article sorting device. Since the transport direction of the article sorting device is switched to the straight-ahead direction side in the remaining state, the downstream side (front side in the traveling direction) of the article is urged in the crossing direction, and the upstream end (rear side in the traveling direction). However, it is urged in the straight direction. As a result, a moment is generated in the article, and the front side of the article faces the intersecting transport direction. That is, the articles are transported from the main transport path to the sub transport path so that the same side is always the front side.
  • Each section of the sorting area has a transport unit composed of a plurality of spherical bodies or short rollers that are rotationally driven, and the rotation axis of each spherical body or each short roller of each transport unit in each section is It is preferable that the orientations are the same and the orientations can be changed in the same direction at the same time, and the orientation of the rotation axis of each spherical body or each short roller can be set for each of the transport units.

Since the direction of the rotation axis of each spherical body or each short roller can be set for each transport unit, the article can be supported in a state of straddling each section. Further, the article can be urged for each section. Therefore, even if the preceding article and the succeeding article are close to each other or in close contact with each other, both articles can be appropriately sorted in each transport direction by switching the transport direction of the transport unit for each section.

Abstract

La présente invention concerne un dispositif de tri d'articles (50) pour commuter la direction de transport d'articles et trier les articles dans un dispositif de transport (1) ayant un trajet de transport principal (2) et un trajet de transport secondaire (3) qui croise le trajet de transport principal (2). Le dispositif de tri d'articles (50) présente une zone de tri (A3) dans la zone du trajet de transport principal (2) dans laquelle le trajet de transport secondaire (3) est raccordé, la zone de tri (A3) est divisée en une pluralité de compartiments dans la direction allant du côté amont au côté aval des articles dans la direction de transport, la direction de transport des articles peut être commutée entre le côté trajet de transport principal (2) et le côté trajet de transport secondaire (3) pour chaque compartiment dans la zone de tri (A3), et la direction de transport de chaque compartiment dans la zone de tri (A3) est commutée vers la direction de transport des articles suivants dans l'ordre depuis le côté amont dans la direction de transport.
