Apparatus for sorting article

Abstract

The article classification device of the present invention can save space, classify articles into a plurality of types, and has good work efficiency. The stocker (5) constituting the article sorting device (2) is provided with first to fifth sliding plates (21A to 21E) on which the sorting trays (4) are placed in a state where a plurality of sorting trays (4) are stacked, and A drive mechanism (22) for holding these sliding plates in upper and lower layers and driving each sliding plate to reciprocate in the horizontal direction. Furthermore, an empty tray supply mechanism (7) is also provided at a position close to the stocker. When the first transfer and placement mechanism (6) places the LED elements (1) on the corresponding sorting tray corresponding to the grade transfer, the stocker moves the sliding plate to expose the sorting tray corresponding to the article. When a predetermined number of articles are accommodated on a required sorting tray, the first transfer and placing mechanism stacks the empty sorting tray held by the empty tray supply mechanism on the sorting tray containing the predetermined number of articles.

Description

technical field [0001] The present invention relates to an article sorting device, and specifically relates to an article sorting device that transfers and places articles corresponding to classification results to a required sorting tray placed on a stocker. Background technique [0002] In the prior art, there are known article sorting devices (patent documents 1 and 2) that are provided with a stocker and a transfer loading mechanism. The stocker is loaded with a plurality of sorting trays for storing articles. The mechanism transfers and places the articles supplied to the supply position on the required sorting tray on the stocker in accordance with the sorting result. [0003] Among them, in the article sorting device of Patent Document 1, the sorting trays are respectively placed on the unloading parts of the three positions set on the stocker, and the chucks as the transfer loading mechanism transfer and place the articles on the unloading parts. On the sorting tray...

Problems solved by technology

[0007] However, in Patent Document 1, when there are many types of article classification, multiple sorting trays must be arranged in the horizontal direction, which will not only increase the installation space, but also increase the operating range of the transfer and placement mechanism, so it will lead to The problem that the takt interval time increases and the classification cannot be performed effectively

[0008] In addition, in Patent Document 1, the transfer and placement of articles and the supply of empty trays are performed by different transfer and placement mechanisms, so the structure of the article sorting device becomes complicated, and there is a problem of high cost.

[0009] Furthermore, in Patent Document 2, only one sorting tray is placed on the slide plate constituting the above-mentioned sorting unit, and a plurality of articles cannot be accommodated. Therefore, the device must be stopped every time a predetermined number of articles are stored on the sorting tray. And the tray is discharged, and there is a problem that the work efficiency of the device is low
