[Industrial applications]

 The present invention relates to a sorting conveyor that sorts or sorts various types of transported goods into a plurality of types.

[0002]

[Prior art]

 Conventionally, sorting conveyors with various structures have been proposed and put into practical use as devices for sorting various types of packages (conveyed goods) into multiple types at a distribution center or into multiple destinations. See, for example, JP-A-4-148719 and JP-B-5-45487). FIG. 4 shows an example of such a sorting conveyor. A traveling path 1 arranged in a loop, and a large number of the traveling paths 1 are arranged on the traveling path 1 along the traveling direction (arrow in the figure). A carriage 2 with a tray which circulates in the direction of (1), a loading chute 4 which is provided at a predetermined position on one side of the traveling path 1, and whose guideway 3 is directed to the traveling path 1, and one side of the traveling path 1. A plurality of sorting chutes 6 provided at other predetermined positions, the guide paths 5 of which are inclined along the conveying direction and the guards 5a and 5b are erected on both sides of the proposed path 5. As shown in FIG. 5, the two trays 2a and 2b, which are front and rear with respect to the traveling direction, are set as one set, and these trays 2a and 2b are provided below the trays 2a and 2b, respectively. A tripper device 7 that tilts toward one side (lower side in the figure) is provided. Since the carry-in chute 4 can be provided at a predetermined position on the other side of the traveling path 1, the carry-in chute 4 can be branched to both sides at the same position.

In this sorting conveyor, in the case of a small load 8, the load 8 is mounted on the tray 2a so that the front end 8a of the load 8 matches the front end of the tray 2a, and the load 8 is set. Of the sorting chute 6, and then the tripper device 7 is driven to tilt the tray 2a to one side of the traveling path 1 so that the load 8 on the tray 2a is guided to the guiding path 5 of the sorting chute 6. To move. Further, in the case of a large baggage 9, the baggage 9 is mounted on the trays 2a and 2b so that the front end 9a of the baggage 9 matches the front end of the tray 2a. The trays 2a and 2b are simultaneously moved to one side of the traveling path 1 by driving the tripper device 7 of each of the trays 2a and 2b to sort the loads 9 on the trays 2a and 2b. The chute 6 is moved to the guideway 5. As described above, the luggage can be sorted into a plurality of courses. The above-mentioned method of mounting the load 8 (9) on the tray 2a (2a, 2b) is referred to as "front combining".

[0004]

[Problems to be solved by the device]

 By the way, in the sorting conveyor described above, for example, in the case of a small load 8, since the load 8 moves to the guide path 5 on the front side in the traveling direction, the drop between the load 8 and the guide 5b becomes large, and The left side in the traveling direction of the luggage 8 moved to the guideway 5 hits the guide 5b and bounces off, which may cause the luggage 8 to rotate or be damaged by a collision with the guide 5b. This becomes more remarkable as the load 8 is smaller. Further, in the case of a large luggage 9, when moving from the trays 2a, 2b to the guideway 5, the luggage 9 does not move along the guide 5b of the guideway 5, and the guide 5a is provided in the middle of the guideway 5. , 5b, there is a risk that the flow will be stagnated, and therefore there is a drawback that the subsequent luggage 9 can not be loaded. Therefore, conventionally, the position of the tripper, which is a branch point, is shifted to the downstream side, but the load 8 does not immediately follow the guide 5b, and the impact cannot be reduced.

The present invention has been made in view of the above circumstances, and by smoothly and promptly transferring various kinds of conveyed goods to a sorting chute, the conveyed goods are not impacted and trouble-free. It is to provide a sorting conveyor that can be quickly sorted or sorted.

[0006]
