Problems solved by technology

[0002] In existing examinations (assessment or election), most of the answering methods for objective questions are done by painting the answer sheet with a pencil, and the painted answer sheet needs to be read by a card reader. Ordinary card readers are generally Single-channel single-output bin design, the card reader automatically stops when encountering an invalid card or a different type of card, and sends an indication signal until the operator takes out the invalid card or a different type of card. Still has strong dependence, cannot realize automatic classification and screening, and it is difficult to improve work efficiency

Embodiment 1

[0027] Example 1, such as Figure 1-3 As shown, in the initial state, the toggle wheel 12 is arranged inside the box body 9. In this embodiment, the telescopic drive unit 10 is an electric telescopic rod, and the axis of the toggle wheel 12 is perpendicular to the axial direction of the telescopic drive unit 10. The box body The side wall of 9 is provided with the protruding groove 15 of the toggle wheel 12. When the telescopic drive unit 10 is extended, the outer side of the toggle wheel 12 can extend out of the box body 9 along the protruding groove 15 and contact the card to hold the card. tight. The bottom plate of the box body 9 is provided with a guide rail 16 parallel to the axial direction of the telescopic drive unit 10. The toggle wheel 12 and the drive motor 11 are all arranged on the slide block 17, and the slide block 17 is guided and matched with the guide rail 16 to facilitate The toggle wheel 12 moves back and forth to reduce friction.

[0028] In order to pr...

Embodiment 2

[0037] Embodiment 2 is substantially the same as Embodiment 1, as Figure 4 As shown, the difference is that the telescopic drive unit 10 includes a push rod 20 hinged at one end to the box body 9, an electric telescopic rod 21, and one end of the electric telescopic rod 21 is in contact with one side of the push rod 20, or The two ends of the telescopic rod 21 are respectively hinged with the ejector rod 21 and the box body 9. In this embodiment, one end of the electric telescopic rod 21 is preferably in contact with one side of the ejector rod 20; The toggle wheel 12 is connected, and the controlled end of the electric telescopic rod 21 is connected with the control end of the controller, wherein the guide rail 16 is an arc guide rail.

[0038] The concrete steps of the control method of this intelligent selection machine are as follows:

[0039] A. The controller controls and controls the automatic card issuing unit 2 to issue cards sequentially according to the specified ti...

Embodiment 3

[0045] Embodiment 3 is substantially the same as Embodiment 1, as Figure 5 As shown, the only difference is that the frame 1 is provided with a blowing pipe 19 located above the screening channel 6 and opening towards the upper cardboard 7, and the end of the blowing pipe 19 is provided with a controlled end connected to the controller. Hair dryer, when step E is performed, the controller controls the blower to work to supply air to the blower pipe 19. Specifically, the blower pipe 19 can be set to an oblique upward state to provide additional upward force for the card in step E to ensure that the card can Enter into the upper splicing board 7.

[0046] The invention relates to an intelligent selection machine and its control method, which integrates card scanning and classification, and can accurately and effectively distinguish valid and invalid cards, or two different types of cards, completely avoiding the need to stop the machine to pick up cards The tedious steps of re...

Abstract

The invention relates to an intelligent evaluation machine and a control method thereof and belongs to the technical field of card reading equipment. The intelligent evaluation machine comprises a machine frame, a controller arranged on the machine frame, an automatic card sending unit, a conveying channel, a card collecting bin and a data acquisition module arranged on one side of the conveying channel, wherein the automatic card sending unit, the conveying channel, the card collecting bin and the data acquisition module are sequentially arranged in the conveying direction of cards. A screening channel composed of a baffle parallel to the conveying channel and a driving assembly is formed between an output end of the conveying channel and the card collecting bin, and the card collecting bin includes an upper paper collecting board and a lower paper collecting board which are positioned at the upper and lower outlets of the screening channel respectively; the driving assembly includesa box body, retractable driving units horizontally arranged on the box body and pulling wheels which are connected with the retractable driving units and provided with a driving motor, wherein a firstcard detection sensor and a second card detection sensor are arranged in the conveying channel and the screening channel respectively. The intelligent evaluation machine can automatically classify invalid cards or cards of different types, does not require manual participation, and achieves efficient automatic classification output.

Description

technical field [0001] The invention belongs to the technical field of card reading equipment, and relates to an evaluation or election equipment, in particular to an intelligent selection machine and a control method thereof.
