Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with Figure of description, the specific embodiment of the present invention is described in detail.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but the present invention can also adopt other to be different from alternate manner described here to be implemented, those skilled in the art can do similar popularization when without prejudice to intension of the present invention, and therefore the present invention is not by the restriction of following public specific embodiment.
Secondly, " embodiment " or " embodiment " referred to herein refers to the special characteristic, structure or the characteristic that may be included at least one implementation of the present invention.Different local in this manual " in one embodiment " occurred not refer both to same embodiment, neither be independent or selective and that other embodiments are mutually exclusive embodiment.
As it is shown in figure 1, it illustrates a kind of filling bottle to correct the agent structure schematic diagram pushed in the embodiment rinsing conveying fill fortune lid spiral cover labeling stamp system.Wherein, described filling bottle is corrected to push to rinse and is carried fill fortune lid spiral cover labeling stamp system to include: correcting device 100, pushing device 200, Portable carrying device 300 and equipment for rinsing 400, go forward one by one device 500, conveyer device 600, filling apparatus 700, fortune lid arrangement 800, impact extrusion device 900, cap rotating device 1000 and labeling stamp device 1100, in this embodiment, filling bottle is corrected to push to rinse and is carried fill fortune lid spiral cover labeling stamp system certainly to further comprises control circuit, the operation control rinsing conveying fill fortune lid spiral cover labeling stamp system is pushed in order to whole filling bottle to be corrected.
Referring to Fig. 2, in this embodiment, correcting device 100 is the cavity of one end open, and its inside cavities wall is provided with the material road 101 risen in the shape of a spiral;Cavity bottom is the accommodating chamber comprising certain space, the interior volume that accommodating chamber is formed is provided with driver (not shown), driver enables to described correcting device 100 and produces whirling vibration power, thus creates a twisting vibration on the vertical axis and a vertical linearity vibration simultaneously.In this embodiment, described driver includes main electromagnet 102 and main vibration spring 103, in one embodiment, main vibration spring 103 can be flat spring, main vibration spring 103 tilts to connect bottom and the top of described accommodating chamber, when switching on power, main electromagnet 103 produces suction therewith, under the effect of electromagnetic attraction, correcting device 100 deviates equipoise and movement, then make to synchronize to reverse around central axis, main vibration spring 103 produces elastic deformation simultaneously, when electromagnetic attraction diminishes, correcting device 100 starts the change direction of motion sharply, and surmount initial equipoise and reach a certain upper limit, this is because main vibration spring 103 has had enough elastic deformation energies, so it is repeatedly performed up and down, it is the formation of high frequency micro breadth oscillation.The result of the produced high frequency micro breadth oscillation of correcting device 100, makes each point except central axis of the material road 101 closely coupled with correcting device 100 itself carry out high frequency micro breadth oscillation all along respective a bit of spatially spiral line tracking.In the process that filling bottle is transferred along material road 101, unification mechanism on material road 101 makes part form unified attitude, due to decrease speed quickly, so filling bottle can float in the air, under gravity, fall into and be again delivered up along material road 101 spiral bottom material road 101, carry out automatic orientation arrangement motion.
And in the present embodiment, to enter owing to filling bottle is follow-up in Portable carrying device 300 and be carried out, so need proal filling bottle bottom screening filling bottle.As shown in Fig. 3~Fig. 6, in material road 101 a certain section or a few sections arranges arc track 104 and bottle falling mouth 105, arc track 104 divides into first half section and second half section with the filling bottle direction of motion, this arc is circular arc, bottle falling mouth 105 is arranged at the second half section of arc track 104, its width is more than the width of filling bottle, and its length is the half of described filling bottle length.So, when bottom filling bottle, proal filling bottle enters this arc track 104, first half section is intersected (referring to Fig. 4) owing to filling bottle can be formed with bottle falling mouth 105, so can't be blocked by bottle falling mouth 105 or drop down;And enter arc track 104 second half section will pass through time (referring to Fig. 5), owing to filling bottle self center of gravity is closer to the particular design of bottom the bottle of filling bottle point and arc track 104 and bottle falling mouth 105, so proal filling bottle will not drop down from bottle falling mouth 105 bottom filling bottle;And when the second half section that the proal filling bottle of filling bottle bottleneck enters this arc track 104 (referring to Fig. 6), owing to filling bottle self center of gravity is divided bottom the bottle of filling bottle, so the proal filling bottle of filling bottle bottleneck drops down from bottle falling mouth 105 due to the unbalance meeting of center of gravity, thus realizing the screening to filling bottle proal bottom filling bottle.
As shown in Figure 10, in this embodiment, arc track 104 is the circular arc of R for radius, so, filling bottle, when affecting without high frequency micro breadth oscillation, agravic deviation (" agravic deviation " refers to the impact of gravity deflection when filling bottle is not risen by the filling bottle caused because material road is spiral uprising shape) herein, is calculated respectively through with following formula by the big I of shared arc track 104 wide (l) in arc track 104 process:
L=d1d3-d1d2+d3d4+d4d5+d5d6(1)
d1d3=Gsin α (2)
d1d2=(b1/2)·cosα(3)
d3d4=2Rsin [(alpha-beta)/2] sin [(alpha+beta)/2] (4)
d4d5=(L-G) sin β (5)
d5d6=(b2/2)·cosβ(6)
Formula (2)~formula (6) is substituted into formula (1) obtain:
L=[(b1-b2)/2]·(cosα-cosβ)+G(sinα-sinβ)+L·sinβ+2R·sin[(α-β)/2]·sin[(α+β)/2];
In formula, b1For filling bottle bottleneck width;b2For filling bottle bottle bottom width degree;L is filling bottle length;G is the filling bottle center of gravity distance to filling bottle bottleneck, measures filling bottle position of centre of gravity between 3/5 L~4/5 L according to filling bottle bottle production standard and by suspension method theory, this numerical value of filling bottle criticized according to difference can Accurate Determining, G in Figure 101、G2It is only difference different time and is in the focus point of diverse location, the not different center of gravity of same filling bottle self;R is filling bottle running orbit radius of curvature;α is initial steer angle during filling bottle entrance arc track;β is that filling bottle is ultimately steering to angle when moving out arc track.
But in practice, when running due to correcting device 100, filling bottle is in high frequency micro breadth oscillation all the time, and filling bottle is by the impact of this high frequency micro breadth oscillation and self gravitation, producing side-play amount (Δ l), its side-play amount (Δ l) calculates with following formula:
Δ l=(μ θ R sinU)/v;
In formula, when μ is characteristic frequency high frequency micro breadth oscillation, the filling bottle average speed by this arc track;U is the inclination angle, material road risen in the shape of a spiral;Setting θ=alpha-beta, its unit takes rad;R is filling bottle running orbit radius of curvature;When v is with characteristic frequency same frequency high frequency micro breadth oscillation, filling bottle is by the average speed of the air line distance identical with the length of arc track.
By principle of stacking, when correcting device 100 carries out high frequency micro breadth oscillation, the width (W) of arc track is set as:
W=l+ Δ l;
The experiment proved that, filling bottle, when the arc track 104 of width, is 100% pass through, and when when can't not occur narrow, filling bottle be blocked, wide, filling bottle does not reach the problem of screening, the problem mostly fallen down from bottle falling mouth 105.
