item separation device

Abstract

The invention relates to an article separation device. The article separation device comprises two support elements, a first contact element and a second contact element, wherein the two support elements are arranged at an interval in a first direction; a separation channel is formed between the two support elements; the first contact element and the second contact element are arranged at an interval in the first direction; the first contact element comprises a first roller; the second contact element comprises a second roller; the first roller and / or the second roller is rotatablely arranged to apply friction forces in directions forming a certain included angle with the first direction separately on articles; and moreover, at least one of the amplitudes and the directions of the friction forces applied by the first roller and the second roller is different, so that the articles are pushed to rotate. In the article separation device, at least one of the amplitudes and the directions of the friction forces applied by the first roller and the second roller is different, so that the articles can be pushed to rotate, and then are separated from the support of the support elements and fall off from the separation channel, and rapid, accurate and automatic separation for the articles is realized.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an article separation device. Background technique [0002] The drawing papers used for large-scale technical examinations are all painted on the front side. In order to protect the screen of the answer sheet, mechanical separation is adopted and the front side of the test paper cannot be touched during the counting process; The drawing paper often has irregular deformation on the surface after drying and handing in the paper. It is difficult to adjust the mechanical paddle sorting equipment, and it is difficult to stably separate the drawing paper with the air blowing sorting equipment. At present, all examination papers are counted manually. [0003] During the examination process, it is necessary to check the test papers many times in the pre-group examination, the issuance, collection and inspection of the examination papers during the examination process, which con...

[0002] The drawing papers used for large-scale technical examinations are all painted on the front side. In order to protect the screen of the answer sheet, mechanical separation is adopted and the front side of the test paper cannot be touched during the counting process; The drawing paper often has irregular deformation on the surface after drying and handing in the paper. It is difficult to adjust the mechanical paddle paging equipment, and it is difficult to separate the drawing paper stably with the air blowing paging equipment. At present, all the examination papers rely on manual counting.

[0003] During the examination process, it is necessary to check the test papers many times in the pre-group examination, the issuance, collection and inspection of the examination papers during the examination process, which consumes a lot of manpower and time. It is easy to make mistakes, once there is an error in the test paper, it will lead to serious teaching accidents
