DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sorting device for a sorting device, and more specifically, a sorting device for sorting is related to a discharging device. The sorting of objects corresponds to the classification at the discharge position, and the sorting that discharges the objects to be sorted from the sorting conveyor is related to the discharge device.

[Conventional technology]

Conventionally, this kind of sorting has used an arm-type branching device with an arm that can rotate at a predetermined angle on the side of the branching point of the conveyor, or a floating conveyor at the branching point of the carrying conveyor. A scraper is installed above the branching point of the conveyor, or a conveyor stack-type branching device that protrudes from the top surface of the conveyor and sends it to the side when the article to be discharged onto the conveyor is conveyed. There were various devices such as a scraper-type branching device that scraped out and branched items by running a chain.

[Problem to be solved by the invention]

The various sorting and discharging devices shown in the above-mentioned conventional techniques are suitable when articles conveyed on a conveyor are conveyed at predetermined intervals in the traveling direction.

However, when the articles to be conveyed are conveyed continuously on the conveyor, the sorting on the conveyor is connected to the article scheduled to be discharged at the discharge position, and the subsequent articles that are not discharged at the discharge position are , it is necessary for the preceding article to temporarily wait on the conveyor during the discharge operation, and the sorting operation has the disadvantage that the discharge operation cannot be performed continuously and smoothly. had the disadvantage of not being able to handle the amount of processing.

Further, according to the above-mentioned conventional sorting and discharging device, the articles to be sorted and discharged are arranged in a fixed manner in which the branching conveyor is arranged in a direction perpendicular to the sorting conveyor or in a direction that gradually branches along the direction in which the sorting conveyor advances. The layout of the expression is

[Effect]

According to the discharging device of the sorting device configured as described above, the trays containing the objects to be sorted transported on the sorting conveyor are
When the sorting of the objects to be sorted corresponds to the classification and reaches the discharge position, an actuating device is actuated to actuate an engaging device in which the engaging member is configured to be able to project. Then, the engaging member of the activated engaging device projects to the lower part of the tray and engages with the inner surface of the peripheral wall of the tray. The tray, while being engaged with the engagement member of the engagement device, is ejected from above to the side of the sorting container by the rotational force of a rotary table on which a plurality of engagement devices are disposed. Then, when the discharged tray reaches a predetermined position on the side of the sorting conveyor, an engagement release device that releases the engagement between the tray and the engagement member acts to disengage the tray and the engagement member. By releasing the engagement, the tray can be discharged together with the objects to be sorted from the sorting conveyor to a predetermined position on the side of the sorting conveyor.

〔Effect of the invention〕

As described above, in the present invention, the trays containing the objects to be sorted are conveyed on the sorting conveyor of the sorting device, and the objects to be sorted are sorted according to the classification at the discharge position, and the objects to be sorted are discharged from the sorting conveyor together with the objects to be sorted. The sorter configured to do so is a discharge device. That is, the trays that have been conveyed by the sorting conveyor and have reached the sorting/discharging position are rotated at approximately the same speed as the conveying speed of the sorting conveyor as the engaging member of the sorting/discharging device engages with the engaging portion of the tray. Since the structure is such that the materials are discharged to a predetermined position on the side, even if they are sent continuously and in tandem on the sorting conveyor, they can be sorted and discharged smoothly without stagnation, making it efficient. Sorting can be discharged.

Furthermore, it can be used for sorting conveyors that run at high speeds by simply adjusting the rotation speed of the rotary table, making it highly versatile.

Furthermore, no matter how the discharge conveyor is arranged according to the layout of the sorting device, sorted items can be discharged to any position (direction) simply by moving the restoring rail position that releases the engagement with the receiving tray. This has the effect that sorting can be performed with a high degree of freedom even in the limited installation space of the sorting device and in the layout of connections with downstream equipment.
