METHOD AND DEVICE FOR SORTING THE ARTICLES (VARIANTS) Russian patent published in 1994 - IPC

FIELD: sorting of articles. SUBSTANCE: method ensures single-row feed of articles item by item to the zone of check, determination of minimum number of required bearing members of the conveyer section on which the article being checked is orthographically projected. Number of bearing members makes it possible to carry out the object when the bearing members forming this section at destination are removed. Destination is determined depending on the indication of sorting which is found through measuring the present magnitude of the sorting indication, comparing it with the preset magnitude in accordance with the requirements of the User and distributing the articles among destinations according to the results of comparison. Then articles are moved to destination and are carried out. Device for sorting the articles has unit 4 for item-by-item feed of articles 2, conveyer 3 with bearing members 4, device 5 for carrying the articles to destinations, device 6 for returning the bearing members to the initial position, automatic control system 7 with device 8 for measuring the present magnitudes of the sorting indication, actuating mechanisms, unit 10 for determination of the number of bearing members on which the article is orthographically projected and unit 11 for indication of motion of the bearing members which is linked with unit 10. Device for measuring the present magnitudes of the sorting indication is connected with unit 10 for determination of the number of bearing members. Provision is made for various versions of conveyer: linear, longitudinal and rotary horizontally closed conveyer. Bearing members may be mounted horizontally on one conveyer, on two conveyers arranged in parallel, as well as at angle to each other forming V-shaped passage for receiving the articles being checked. The device is operated with the aid of automatic control system by algorithm in accordance with the User's requirements. EFFECT: enhanced reliability. 11 cl, 13 dwg
