Description
Technical field
The present invention relates to a kind of paper detection, relates in particular to a kind of infrared reflection formula paper detection.
Background technology
In the automatic carriage device, be a kind of indispensable assembly in order to the paper detection of test paper tension position.But along with the variation of automatic carriage device paper feeding, the effect of paper detection detection paper significantly has influence on the running of automatic carriage device.
Fig. 1 to 3 shows a kind of scheme drawing of traditional paper detection.As shown in Figure 1, traditional paper detection 100 comprises first guide plate 110, second guide plate 120, projector 130, receptor 140 and catadioptre 150.First guide plate 110 and second guide plate 120 constitute paper travel path 102.When not having paper to pass through this paper travel path 102, the signal S that projector 130 sends can pass first opening 112 of first guide plate 110 and second opening 122 of second guide plate 120, pass through second opening 122 and first opening 112 again by catadioptre 150 reflections then, receive by receptor 140 then.
As shown in Figure 2, when paper 104 passed through this paper travel path 102, the signal S that projector 130 is sent was received by paper 104, can't reflex to receptor 140.
Yet when paper 104 has smooth surface, or paper 104 as shown in Figure 3, can produce the signal S ' of scattering when being twisted, and receives and be received device 140, thereby makes paper detection produce misoperation.
Therefore, how providing a kind of and can not produce the paper detection of misoperation because of Deformation of Paper, is problem to be solved by this invention.
Summary of the invention
The purpose of this invention is to provide a kind of reflection type paper detector, it can effectively prevent Deformation of Paper and produce misoperation.
In order to achieve the above object, the invention provides a kind of reflection type paper detector.Reflection type paper detector comprises first guide plate, second guide plate, projector, receptor and reflecting part.First guide plate and second guide plate constitute the paper travel path.Be formed with the first signal feed opening and the first signal output opening on first guide plate.Be formed with secondary signal feed opening and secondary signal outlet opening on second guide plate.Projector is arranged on first side of paper travel path and the first signal feed opening of close first guide plate.Receptor is arranged on first side of paper travel path and the first signal output opening of close first guide plate.Reflecting part is arranged on second side of paper travel path and near second guide plate, this second side is at the opposition side of described first side.Projector sends signal and arrives reflecting part by the first signal feed opening and secondary signal feed opening, and arrives receptor by the reflecting part reflection by the secondary signal outlet opening and the first signal output opening.
In above-mentioned state, secondary signal feed opening and secondary signal outlet opening can be merged into one second opening.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and in conjunction with the accompanying drawings, be elaborated hereinafter.

The specific embodiment
Fig. 4 to 5 shows the scheme drawing according to the paper detection of first embodiment of the invention.Shown in Fig. 4 to 5, a kind of reflection type paper detector 1 of present embodiment comprises first guide plate 10, second guide plate 20, projector 30, receptor 40 and reflecting part 50.
Both constitute paper travel path 2 first guide plate 10 and second guide plate 20.Be formed with the first signal feed opening 12 and the first signal output opening 14 on first guide plate 10.Be formed with secondary signal feed opening 22 and secondary signal outlet opening 24 on second guide plate 20.First distance D 1 between the first signal feed opening 12 and the first signal output opening 14 is greater than the second distance D2 between secondary signal feed opening 22 and the secondary signal outlet opening 24.
Reflecting part 50 is catadioptre normally, and its second side that is arranged on paper travel path 2 is also near the opposition side of second guide plate, 20, the second sides in first side.
When not having paper to exist in the paper travel path 2, as shown in Figure 4, projector 30 sends signal S and arrives reflecting part 50 by the first signal feed opening 12 with secondary signal feed opening 22, and arrives receptor 40 by reflecting part 50 reflections by the secondary signal outlet opening 24 and the first signal output opening 14.
When having paper in the paper travel path 2, as shown in Figure 5, projector 30 sends signal S and arrives paper 4 by the first signal feed opening 12.Because the cause that has first middle part of guide plate 10 on figure to stop, so no matter by paper reflection or absorption, signal S can not arrive receptor 40.Can avoid the situation of reflection type paper detector 1 erroneous judgement thus.
For the ease of allowing user or maintainer adjust, reflection type paper detector 1 can also comprise adjusting mechanism 60, and it is connected to projector 30 and receptor 40, in order to for example to adjust the position of projector 30 and receptor 40 along the horizontal direction of drawing.Adjusting mechanism 60 can be to rely on plus-minus screw or motor and form.In an example, projector 30 and receptor 40 can relative motions, and 60 of adjusting mechanisms are not adjusted the position of projector 30 and receptor 40.Perhaps, projector 30 can be fixed on substrate 5 with receptor 40 and can not relative motion, and adjusting mechanism 60 can be adjusted the position of substrate 5 and adjust the position of projector 30 and receptor 40 synchronously.Perhaps, can provide adjusting mechanism in addition or utilize adjusting mechanism 60 to adjust the position of reflecting part 50.
Fig. 6 shows the scheme drawing according to the paper detection of second embodiment of the invention.As shown in Figure 6, the reflection type paper detector 1 ' of present embodiment is similar to first embodiment, and difference is only to be formed with on second guide plate 20 second opening 26.When in paper travel path 2, not having paper to exist, projector 30 sends signal S and arrives reflecting part 50 by the first signal feed opening 12 and second opening 26, and arrives receptor 40 by reflecting part 50 reflections by second opening 26 and the first signal output opening 14.
The front-view schematic diagram of the crooked detection module of Fig. 7 display application paper detection of the present invention. the schematic top plan view of the crooked detection module of Fig. 8 display application paper detection of the present invention. shown in Fig. 7 and 8, crooked detection module comprises two reflection type paper detectors 1 that are positioned at the left and right sides, pass through the time point of two reflection type paper detectors 1 in order to the leading edge that detects paper 4 respectively, detect the crooked amount of paper thus, proofread and correct the crooked amount of paper for subsequent treatment.
Rely on paper detection of the present invention, significantly limited the scope of the signal that receptor can receive, feasible when twisting or level and smooth paper when passing through, can not produce the situation of erroneous judgement.Therefore, paper detection provided by the present invention has significantly increased its suitable application area.
The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to convenient explanation technology contents of the present invention; but not with narrow sense of the present invention be limited in the foregoing description; under the situation that does not exceed spirit of the present invention and claim; the many variations of being done is implemented, and all belongs in the scope of protection of the invention.
