Further, it is preferable to cover the guide wheels 16 with a cover portion 19 so that the guide wheels 16 are not exposed on the upper surface side of the belt 14.

In order to sort the conveying tray unit 10 according to the destination of conveyed objects, a tray unit sorting operation device 28 as shown in FIGS. 5 and 6 is provided at a required sorting location. As shown in the figure, the tray unit sorting actuating device 28 includes a guide track device 40 that guides the guide wheel 16, and a gate device 4 that can move up and down to switch and guide the guide wheel 16 along the guide track device 40.
2, and an actuating device 4 for vertically operating the gate device 42.

As clearly shown in FIG. 5, a pair of straight tracks 45.45 extend parallel to the conveying direction at intervals, and two sets of X-shaped slopes are provided between the straight tracks 45.45. As shown in FIG. 2, a guide wheel 16 located on the underside of the belt 14 guides and engages with a guide track device 40.A gate device 42, which can move up and down, is fixed. A gate 49 is fixed to the upper end of a vertical operating rod 48 which is attached to the frame 2 of the frame 2 so as to be movable up and down, and a wheel 50 is rotatably provided to the lower end of the operating rod 48. It consists of a spring 51 and a guide track device 40.
are arranged at each intersection of the straight track 45 and the inclined track 46. Further, an actuating device 44 for vertically operating such a gate device 42 is provided so as to carry a wheel 5o for each gate on a slide plate 52 provided slidably in the transport direction with respect to the frame 2. a cam member 53, a hydraulically or pneumatic actuator 54 provided to slide the slide plate 52 in the transport direction, and a bracket 57 mounted on the frame 2 to slide and support the slide plate 52 via a bearing 55. 58.

In the automatic sorting apparatus of the present invention configured in this way, the inner leg portion 17 of the conveying tray unit 10 is connected sequentially to the adjacent conveying tray unit 10 by the dog 20, so that it is configured in an endless manner. , the guide wheels of each leg 17.18 are driven by an electric motor SO via a drive chain 32 on which is mounted a bracket 36 having a dog pusher 34 which engages in meshing engagement with the dog 20 connecting the transport tray unit 10 in this way. 22 and 23, it is driven to run along the guide rails 4 and 5.

The automatic sorting system of the present invention, which is driven to travel in this manner, is capable of loading conveyance objects of any shape or type, including silk articles, bags, regular shapes, and irregular shapes, on each conveyor tray unit (10) of the apparatus at the loading section. It is transported to the sorting location. In sorting the conveyed objects, a suitable control device such as a computer gives a sorting instruction to the tray unit sorting actuating device 28 at a predetermined sorting position and actuates the actuator 54 according to various codes displayed on the conveyed objects.

For example, if the actuator 54 is actuated as shown in FIG. The guide wheel 16L on the left side in the direction of travel hits the raised gate 49a and enters the inclined track 46 from the straight track 45,
The right guide wheel 16R passes over the lowered gate 49b of the straight track 45 and moves outward from the straight track 45.

Therefore, the left guide wheel 16 is connected to the inclined track 46.
As the transport tray unit 10 moves, the belt 14 is moved in a direction perpendicular to the transport direction, that is, the upper surface of the belt 14 is moved in the direction of arrow B. At the intersection of the inclined tracks 46, the guide wheel 16L is further moved along the inclined track 46 by the raised gate 49c and the lowered gate 49d,
The belt 14 is therefore rotated further. When the guide wheel 16L reaches the intersection of the straight track 45 and the inclined track 46, the belt 14 has been rotated by 1/4 and the conveyed objects for sorting have not yet been sent out.

Next, the previous guide wheel τ/L-1'6 L passes through the lowered gate 49e of the straight track 45 and moves outward, and the next guide wheel 16 on the left passes through the lowered gate 49f of the straight track 45. There are people on the straight track-45.
Then, it is guided to the next X-shaped inclined track 46 by the raised gate 49g. Therefore, guide wheel 1
6 moves along the inclined track 46 and the inclined track 4
49h at the intersection of the inclined track 46 and the straight track 45. Movement of the guide wheel 16 to this position causes the belt 14 to rotate an additional 1/4 turn, thus making a total of 1 turn.
/2 rotation, and the conveyed object placed on the belt 14 is completely pushed out from above the belt 14 to the left and sorted into a predetermined sorting chute 8, where required sorting is performed.

In this way, the automatic sorting system of the present invention operates the actuator of the tray unit sorting actuator to operate the gate device at a predetermined sorting location in response to a sorting command from an appropriate control device such as a computer. The belt is operated by guiding and moving the guide foil of the belt of the conveying tray unit by a necessary guide track device, and the conveyed objects placed on the belt can be sorted into predetermined positions. In addition, since a belt is used for the conveyance tray unit, it is possible to convey and sort any conveyed object, regardless of its shape or type, such as silk, bags, regular shapes, irregular shapes, etc.
