Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in this utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the planar structure schematic diagram of Double-sheet detection device one detailed description of the invention detected for front cover and back cover of the present utility model.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, this utility model is described in detail; but it should what illustrate is; these embodiments are not limitation of the utility model; those of ordinary skill in the art, according to the equivalent transformation in these embodiment institute work energy, method or structure or replacement, belong within protection domain of the present utility model.
As it is shown in figure 1, the Double-sheet detection device detected for front cover and back cover of the present utility model, it can install additional and be positioned at manufacture this equipment cover, back cover exit position place, and the double sheet problem of front cover, back cover is detected.Specifically, described Double-sheet detection device, in relevant device, original running roller 200 is arranged, and described Double-sheet detection device includes: the first detection wheel 10, second detects wheel 20, alarm mechanism, governor motion.
Forming the feed station of front cover or back cover between described first detection wheel 10 and the original running roller of described equipment, when front cover 300 or back cover 300 are carried, described first detects wheel 10 and described running roller synchronous axial system.Described first detection wheel 10, near described second detection wheel 20 setting, has therebetween spacing, thus, when front cover or back cover are individual, due to the existence of spacing, the second detection wheel 20 will not be driven.When front cover or back cover occur that double sheet or multiple and paper have grand bar problem, described first detection wheel 10 moves, and contacts with the second detection wheel 20, thus driving described second detection wheel 20 rotation.Wherein, the minima of described spacing is 0.1mm.It is supported additionally, pass through to support spring 30 between described first detection wheel 10 and described second detection wheel 20.
As a kind of embodiment, described first detection wheel 10 is positioned at the underface of described second detection wheel 20, and directly over the original running roller of the equipment that is positioned at, and between described first detection wheel 10 and described second detection wheel 20, there is spacing, described spacing is corresponding with the thickness of a piece of paper, described first detection wheel 10 also has the amount of movement on vertical direction, and described amount of movement is corresponding with described spacing.Thus, when front cover or back cover occur that double sheet or multiple and paper have grand bar problem, described first detection wheel 10 moves up, and drives the second detection wheel 20 rotation, during the second detection wheel 20 rotation, triggers alarm mechanism and reports to the police.
Described alarm mechanism is for carrying out automatic alarm when double sheet or multiple and paper have grand bar problem occurring.Specifically, described alarm mechanism is near described second detection wheel 20 setting, and described second detection wheel 20 triggers described alarm mechanism by the mode rotated.In order to realize this purpose, described second detection wheel 20 is additionally provided with and stirs pin 21, during described second detection wheel 20 rotation, trigger described alarm mechanism by described pin 21 of stirring, to carry out automatic alarm.
Further, described alarm mechanism includes microswitch 41 and alarm unit, and wherein, described microswitch 41 is electrically connected with described alarm unit, and controls the work of described alarm unit.For achieving the above object, described microswitch 41 has initial position and trigger position, and when described microswitch 41 is positioned at described initial position, described alarm unit is not reported to the police;When described alarm unit is positioned at described trigger position, described alarm unit starts, and can carry out automatic alarm.Correspondingly, when described second detection wheel 20 remains stationary, described microswitch 41 is in described initial position;During described second detection wheel 20 rotation, described microswitch 41 is in described trigger position.Further, during described second detection wheel 20 rotation, it triggers described microswitch 41 by microswitch sheet.
Described governor motion is for regulating the spacing between described first detection wheel 10 and the second detection wheel 20, and specifically, described governor motion includes regulating handle 51 and regulating support 52.Additionally, described Double-sheet detection device also includes fixed mechanism, described fixed mechanism includes fixed mount 61 and fixing bar 62, wherein, described fixing bar 62 is vertically installed on described fixed mount 61, and meanwhile, described first detection wheel 10 and the second detection wheel 20 are connected on described fixed mount 61.Described adjustment handle 51 is connected with described fixing bar 62 by adjusting rod 53, and described adjusting rod 53 is set with adjustment spring 54, and described adjustment spring 54 is at described fixing bar 53 and regulates between support 52.When needing to regulate the spacing between the first detection wheel 10 and the second detection wheel 20, can pass through to rotate described adjustment handle 51 and realize.
In sum; the Double-sheet detection device detected for front cover and back cover of the present utility model installs additional and is positioned at manufacture this equipment cover, back cover exit; occur double sheet or multiple and when paper has grand bar; first detection wheel drives the second detection wheel; thus triggering alarm mechanism automatic alarm; inform that machine operations person has defective products (double sheet, grand bar), it is not necessary to shut down, it is ensured that the quality of product.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
