EXAMPLES A sorting chute in an article sorting machine of the present invention will be described below with reference to the illustrated examples. In the figure, reference numeral 1 denotes a running path having a loop shape or other required shape formed in accordance with a transportation process of sorting articles. Although the supply unit 2 is provided at one location in this embodiment, it can be provided at two or more locations, and each supply section 2 has 3 to 4 input devices, and the sorting unit is also provided. The section 3 is provided with a large number of sorting chutes 4, 4, ... 4, Adjacent to one or both sides of the straight portion of the traveling path 1. In addition, the installation location and the number of the supply unit 2 and the sorting unit 3,
Furthermore, the shape of the traveling path is not limited to this.

As shown in detail in the figure, the sorting section 3 has a large number of sorting chutes 4 at predetermined intervals with a predetermined inclination angle.
4 are arranged, and the goods transferred from the feeding conveyor of the supply unit 2 are circulated along the traveling path 1 to be sorted by the destination or the like and delivered to the sorting chute 4 at a predetermined position for sorting. In addition, along with the sorting section 3 in which the large number of sorting chutes 4 and 4 are arranged, a sorting commodity receiving stand, a conveyor, or the like is arranged in a parallel or orthogonal direction in the lower portion, if necessary.

As shown in detail in FIG. 1, each sorting chute 4 is provided with a chute bottom plate 42 with a required inclination angle so that the sorting articles slide on the bottom surface between the partition plates 41, 41 for partitioning adjacent sorting chutes. At the same time, a movable shelf 43 is provided on the upper end side of the sorting chute, and a movable stopper 44 is provided on the lower end side. The movable shelf 43 has a size capable of closing the upper opening position of the sorting chute 4 and supports the base end side of the sorting chute 4 via a support shaft 45 so that the movable chute bottom plate 42 can swing.
Is provided with a drive device 46 which is driven by air or a hydraulic cylinder, an electric motor or the like for swinging the same.

The main body of the drive device 46 is attached to the partition plate 41 or the frame, the tip of the rod is pivotally attached to a part of the movable shelf 43, and the link pin 47 is attached to the partition plate 41 on the side of the movable shelf 43. It penetrates through the perforated elongated hole 48 and is projected to the outside. When the movable shelf 43 swings around the support shaft 45, the elongated hole 48 has the same arc shape as that drawn by the link pin 47, and thus also serves as a guide when the movable shelf 43 swings.

A movable stopper 44 is provided on the lower end side of each sorting chute 4 such that its base end side is swingable on the chute bottom plate 42 side via a support shaft 49 and has an arc shape provided on the partition plate. A link pin 51 is projectingly provided on a side portion of the movable stopper 44 so as to penetrate the elongated hole 50. Then, a link 5 is provided between the movable shelf and the link pin 47, 51 of the stopper.
2 is installed so that when the movable shelf swings, the movable stoppers also interlock with each other via a link so as to swing in mutually opposite directions. The link 52 may be omitted, and the movable shelves and the movable stoppers may be provided with drive devices, respectively, so that the operations in opposite directions can be interlocked with each other.

In the sorting apparatus having the above-described structure, when the products to be sorted are supplied from the supply unit to the transport carriage traveling on the traveling path, they are transported to the sorting chute designated by the traveling of the transport carriage to sort at a predetermined position. At the chute position, the tilting device tilts the loading platform of the cart to dispense the goods from the loading platform and transfer them to the sorting chute side. At this time, when the sorted products are sent to the lower end portion of the sorting chute, the movable stopper is erected when the movable shelf is tilted, whereby the sorted products are stopped in the sorting chute by the movable stopper.

[0013] Then, the commodities are sequentially sorted, and if the sorting destinations are different before the articles accumulated in the sorting chute are taken out, the movable shelves are operated by the drive device to stand up. As a result, the sorting chute is closed at the upper position, and the movable stopper is collapsed at the lower part to discharge the products in the chute, and at the same time, the next sorted product is temporarily held on the movable shelf. For this reason, even if the sorting destinations of the products that are sorted continuously using the same sorting chute are different, the sorting can be surely performed only by operating the movable shelves and stoppers.
