According to the present invention, the installation cost for joining two sorting chute conveyors carrying cargo sorted by the sorting machine to the joining chute conveyor is low, and the sorting can be performed continuously even if the goods are concentrated in the same shipping direction, and the work efficiency is reduced. To a sorted cargo consolidation system.

Conventionally, cargo collected at a collection point such as a truck terminal is sorted by shipment direction by a sorting machine or the like and seated on a sorting chute conveyor and then conveyed to the rear of the truck for shipment. In this case, when a lot of sorting processing capacity is required, it is necessary to install a plurality of sorting machines in response to this, and finally, the cargo classified in the same shipment direction is finally joined to one chute conveyor.

One embodiment of a conventional sorted cargo confluence system that meets these conditions is shown in FIG. In the drawings, reference numerals 1 and 2 denote chute conveyors for carrying cargo classified in the same shipping direction, and arrows indicate a conveying direction. In such a system, the chute conveyors 1 and 2 have the same effective width with each other, so that merging cargoes at the same time is likely to cause cargo blockage. Therefore, in order to prevent this, the cargo on one chute conveyor 1 flows preferentially, and the cargo on the other chute conveyor 2 is joined to the confluence of the chute conveyor 1 by a sensor which detects the presence or absence of cargo at the confluence part. When there is cargo in 3), the chute conveyor 2 is stopped, and after confirming the passage of the cargo of the confluence part 3, the chute conveyor 2 is started and the cargo is joined on the chute conveyor 1 by the way. . Specifically, a photoelectric sensor is installed upstream of the confluence of the chute conveyor 1, and after the previous cargo passes (shields), there is no cargo on the conveyor under the condition that the next cargo does not pass (shields) within the set time. Judging, the cargo on the chute conveyor 2 is thrown in on the chute conveyor 1. Documents describing such a method include Patent Document 1 and Patent Document 2.

This method is excellent in that the merging control is automatically performed, so that the cargo can be directly transported to the truck without the need for one-handed work. However, the control for the automatic merging is required, and the installation cost is high. In addition, if the cargo on the chute conveyor 2 is temporarily suspended while the cargo on the chute conveyor 1 is concentrated, if more than this cargo is sorted, it becomes full, and the diverter locks the cargo to flow downstream of the classifier. This lowers the sorting ability. Therefore, it is necessary to divide the chute conveyor in order to hold much cargo, which also increases the installation cost. In addition, the cargo flowing at the downstream end of the classifier must be sorted again automatically or manually, thereby reducing work efficiency.

On the other hand, if two sorters are installed in the same manner as the method shown in Fig. 1, the two chute conveyors are not joined to each other, but there is a method of proceeding in parallel to the rear of the truck for shipment. One embodiment of such a classification cargo confluence system is shown in FIG. This system is excellent in that confluence control is unnecessary and there is no waiting cargo, so it is not necessary to divert the cargo upstream of the chute conveyor, but the width of the conveyor is doubled after the two conveyors are parallel. At the downstream end, twice as much space is needed and floor space is reduced. Therefore, when the sorting processing capacity is required and a large number of chute conveyors are required, it is very difficult to adopt. In addition, since the two conveyors are positioned in parallel as it is, alignment of cargoes by one hand is necessary.

In this embodiment, the confluence control is used to join the sort chute conveyors, but this is a method used when the sort chute conveyor has more than two lines, for example, in the case of four lines, in this case The cargoes are filled on the conveyors 3 and 4, and when more of the cargo is sorted, the classifier diverter locks and flows the cargo downstream of the classifier. Since the first consigned cargo is discharged and merged from the sorting chute conveyors (1, 2) to the joining chute conveyor without installing confluence control, this part is inexpensive to install and reduce the cost of the system. Can be. In addition, since the sorting chute conveyors 1 and 2 directly joining the joining chute conveyor do not need to discharge cargo to the downstream end of the sorting machine or stay in the chute conveyor, equipment for this is unnecessary, thereby reducing costs. . In addition, since the effective width of the combined chute conveyor is set to 1.5 times or more and less than 2.0 times the effective width of the split chute conveyor, the same effects as those of the above-described embodiment can be obtained, such as clogging of cargo and avoiding damage to cargo. .
