Description

A kind of pay-off

Technical field

The utility model relates to the conveying machinery field, refers to especially a kind of pay-off.

Background technology

Producing supermatic today, operation has obtained the more and more segmentation of precise treatment, and increasing producer or workshop may only be produced for one or several operation.Therefore, productive force is greatly improved.But, exactly because the segmentation of operation, from the original paper that obtains of an operation may come from different manufacturers or workshop, thereby pay-off has been proposed to great test.Traditional pay-off adopts air cylinder driven or manipulator sorting mostly.Although such pay-off can meet the demand of automation, because its complex structure, manufacturing cost are quite high, and also stable not.Therefore, a kind of pay-off need to be proposed, in order to meet in the market the demand to feeder structure is simple, with low cost, result of use is stable.

The utility model content

The utility model proposes a kind of pay-off, solved in prior art that feeder structure is complicated, manufacturing cost is quite high, and stable not problem.

The technical solution of the utility model is achieved in that

A kind of pay-off, comprise: mechanics and electric part, mechanics comprises: circular hopper, electromagnet, armature, shell fragment and base, circular hopper madial wall is provided with spiralling spiral conveying road, circular hopper lower surface is fixedly connected with armature, and electromagnet is fixedly connected with base, and the shell fragment that circular hopper is arranged by rule is connected with base, shell fragment quantity is n, 3≤n≤6; Electric part comprises: inductive detection module and control output module, inductive detection module and control output module are electrically connected, inductive detection module comprises shock sensor, and shock sensor is arranged on described circular hopper, controls output module and electromagnet and is electrically connected.

Further, described inductive detection module also comprises rectifier filer and linear amplifier, and linear amplifier and described shock sensor are electrically connected, and described rectifier filer and linear amplifier are electrically connected.

Further, described control output module comprises: silicon controlled toggle and impulse deviser, and impulse deviser is electrically connected with silicon controlled toggle, electromagnet respectively, and silicon controlled toggle and rectifier filer are electrically connected.

Further, described shell fragment is along the distribution that is centrosymmetric of described circular hopper axis.

Further, described shell fragment quantity is four.

Further, tile in described spiral conveying road and be useful on the resin bed of damping and slide-prevention.

Further, go back rule on described base and be provided with damping rubber pad.

The beneficial effects of the utility model are: pass through such scheme, replaced excitation and the erasing characteristics of electromagnet will be utilized, alternately attract, break away from armature, make elastic element that elastic deformation, recovery alternately occur simultaneously, make hopper alternately descend, rise, thereby make the workpiece in circular hopper produce displacement, thereby realize feeding, the utility model is simple in structure, be easy to manufacture, and stable working state.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The planar structure schematic diagram that Fig. 1 is an embodiment of a kind of pay-off of the utility model;

The circuit theory connection structure schematic diagram that Fig. 2 is pay-off shown in Fig. 1.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.

The embodiment referring to the utility model pay-off shown in Fig. 1 and Fig. 2 comprises: mechanics and electric part, mechanics comprises: circular hopper 1, electromagnet 3, armature 2, shell fragment 5 and base 4.Circular hopper 1 madial wall is provided with spiralling spiral conveying road 6, circular hopper 1 lower surface is fixedly connected with armature 2, electromagnet 3 is fixedly connected with base 4, and the shell fragment 5 that circular hopper 1 is arranged by rule is connected with base 4, and described shell fragment 5 is along the distribution that is centrosymmetric of described circular hopper 1 axis.Preferably, shell fragment 5 quantity are 4, also can be three, five or six, the stability of shell fragment 5 quantity and the 1 vibrations feeding of circular hopper is linear, more shell fragments 5 arrange, circular hopper 1 stability when the vibrations feeding is higher, thereby more be not prone to the feeding caused because of single shell fragment 5 elastic failures, does not end situation.

Base 4 is provided with the damping rubber pad 7 that rule distributes, and because of the pay-off vibrations, damage is caused in ground when preventing from shaking feeding.The 6 inside face tilings of spiral conveying road are useful on the resin bed of damping and slide-prevention, make when helical feed, and workpiece can not occur because vibrations and spiral conveying road 6 bump damaging, and is unlikely to occur the landing phenomenon.

Electric part comprises: inductive detection module 12 and control output module 11, inductive detection module 12 and control output module 11 are electrically connected.Inductive detection module 12 comprises shock sensor, rectifier filer and linear amplifier, and linear amplifier and described shock sensor are electrically connected, and described rectifier filer and linear amplifier are electrically connected, and shock sensor is arranged on described circular hopper 1.Preferably, shock sensor adopts the condenser shock sensor, highly sensitive.Control output module 11 and comprise silicon controlled toggle and impulse deviser, impulse deviser is electrically connected with silicon controlled toggle, electromagnet 3, power supply respectively, and silicon controlled toggle and rectifier filer are electrically connected.

In working order, under the effect of the impulse singla that electromagnet 3 sends at impulse deviser, armature 2 is alternately attracted, discharges, simultaneously, alternately elastic deformation and recovery occurs in shell fragment 5, thereby makes circular hopper 1 alternately fall, rise.Workpiece in circular hopper 1 produces displacement, thereby enter spiral conveying road 6, realizes feeding.

Simultaneously, because the continuous conveying of workpiece causes the variation of the total mass of circular hopper 1 and interior workpiece thereof, or because add suddenly a large amount of workpiece, this mass change can cause the variation of default vibration frequency and intensity.Shock sensor is sensed the variation of circular hopper 1 vibration frequency and amplitude, mechanical signal is converted into to electric signal transmission and to linear amplifier, carries out the signal amplification, signal after amplification conducts to rectifier filer, send signal instruction through silicon controlled toggle paired pulses producer again after excluding the interference signal, the impulse singla that impulse deviser is sent changes, again the impulse singla after changing is issued to electromagnet 3, the attraction of electromagnet 3 discharges frequency and change of flux, thereby reaches required vibration frequency and the amplitude of circular hopper 1 met after quality changes.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
