Therefore, a large number of chutes are arranged adjacent to each other according to the number of sorts.
Sorting of each chute is determined in advance, and it is impossible to sort more than the number of sort chute. For this reason, when the number of sorting destinations increases, the number of shoots inevitably increases, and the entire sorting apparatus becomes larger. There is no problem as long as the sorting destination is always constant for each shot, but depending on the application, the sorting destination may be switched and used at certain intervals. In such a case, since the sorting destination is different even for the same chute, it cannot be used continuously.

Therefore, according to the present invention, a chute that is independent for each sorting destination is sorted by providing movable shelves and stoppers at the base end (upper end) and distal end (lower end) of the chute so as to be interlocked. The aim is to reduce the number of adjacent sorting chutes, reduce the size of the equipment, and efficiently sort products by using the same sorting chutes according to the work time as chutes for different sorting destinations. And

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sorting chute in an article sorting machine according to the present invention will be described below with reference to the illustrated embodiment. 1 in the figure
Is a traveling path having a required shape formed in accordance with a loop-like or other sorting article conveying process. The traveling section 1 has an arbitrary position on the traveling path 1 and a supply section 2 for sorting commodities and a sorting section 3 for sorting. In this embodiment, the number of the supply units 2 is one. However, the number of the supply units 2 can be two or more, and each supply unit 2 has three to four input devices. A large number of sorting chutes 4, 4... 4 are arranged adjacent to one or both sides of the straight section of the traveling path 1. In addition, the installation location and the number of the supply unit 2 and the sorting unit 3 and the shape of the traveling path are not limited thereto.

As shown in detail in the drawing, the sorting section 3 has a large number of sorting chutes 4 at predetermined intervals with a predetermined inclination angle.
4 is disposed, and the goods transferred from the feeding conveyor of the supply unit 2 to the transport trolley circulating along the traveling path 1 are sorted by the destination or the like, delivered to the sorting chute 4 at a predetermined position, and sorted. At the same time, along the sorting section 3 on which the large number of sorting chutes 4 and 4 are provided, a sorting product receiving table or a conveyor or the like is arranged in a lower part along a parallel or orthogonal direction as required.

As shown in FIG. 1, each of the sorting chutes 4 is a partition plate 41 for separating adjacent sorting chutes.
A chute bottom plate 42 is provided at a required inclination angle so that the sorted articles slide down on the bottom surface, and a movable shelf 43 is provided at an upper end of the sorting chute and a movable stopper 44 is provided at a lower end of the chute. The movable shelf 43 has a size such that the upper opening of the sorting chute 4 can be closed.
The chute bottom plate 42 is provided with a drive unit 46 driven by air or a hydraulic cylinder, an electric motor, or the like for swinging the chute bottom plate 42.

The main body of the driving device 46 is attached to a partition plate 41 or a frame, and a rod end is pivotally attached to a part of the movable shelf 43, and a link pin 47 is provided on a side portion of the movable shelf 43. Through the long hole 48 pierced to the outside. The long hole 48 is provided with a movable shaft 43 for supporting a shaft 45.
When the movable shelf 43 swings around the movable shelf 43, the movable shelf 43 also serves as a guide when the movable shelf 43 swings.

A movable stopper 44 is provided at the lower end of each of the sorting chutes 4 so that the base end thereof is swingable on the chute bottom plate 42 side through a support shaft 49, and an arc-shaped stopper is provided on the partition plate. A link pin 51 protrudes from the side of the movable stopper 44 so as to penetrate into the long hole 50. A link 52 is provided between the movable shelf and the link pins 47 and 51 of the stopper so that when the movable shelf swings, the movable stopper also swings in opposite directions via the link.
