The specific embodiment
Through specific embodiment graininess medicament metering dispensing device of the present invention is done further to describe in detail below.
The end at each said each position of embodiment of this description is consistent with the end and the side of the equal dative wheel of side, and promptly the lattice wheel axis is oriented to end, and the parallel axes direction is a side.
The present invention is based on research, disclose micropowder and can be ground fixed and parts are transported in locking, also can import the moisture locking that bonds from the external world and transport parts through the slit at friction surface to micropowder behavior in the dispensing device; In other words, in case micropowder gathers, all can locking transport parts no matter do to wet; The basic structure of the existing the object of the invention of historical facts or anecdotes comprises two aspects; The one, take turns as transporting parts with the lattice of axis horizontal setting, make carriage direction to greatest extent near gravity direction, all give outlet and the trend of micropowder to confirm at each position; Weaken its cumulative condition greatly, with the fixed locking on the surface of significantly reducing friction; The 2nd, with drug storage bottle upper and lower opening and add a cover, when being in storage configuration, upper flap presses closer lid; The tight bottom of The lower flap; The slit of transporting relevant each parts with it of parts just no longer is communicated with extraneous, and when opening additional granule suitable for reading, end opening still covers tightly; Said slit directly is not communicated with extraneous, the bonding locking of making moist and causing with the micropowder importing steam that accumulates in these slits of remarkable minimizing.
Present embodiment is promptly showed the concrete anti-lock structure of technique scheme, and the structure of associated components and assembly relation be referring to Fig. 1, assemble ready and device that granule is gone in storage referring to Fig. 2.Wherein:
(1) to the fixed locking of friction surface---among Fig. 1, Fig. 2, the hole shape lattice wheel chamber 7-3 of axis horizontal is set in the lattice wheel seat 7.Lattice wheel 8 rotates and is arranged in the lattice wheel chamber 7-3, the two be the hole and spool between movingly.With respect to horizontally rotating of axis normal setting, the lattice wheel 8 that axis horizontal is provided with promptly belongs to vertical rotation.Several hold medicine lattice 9 the periphery uniform distribution of lattice wheel 8, and each volume that holds medicine lattice 9 all equates.It is fixing that the lattice wheel seat 7 of lattice wheel 8 of having packed into is put into drug reservoir 3 along Fig. 1 up arrow direction; At this moment; Lattice wheel seat 7 is sealed and matched with the discharging opening 3-2 of drug reservoir 3, is communicated with the spatial lattice wheel seat of drug reservoir 3 drug storages upper shed 7-1 for advancing the medicine passage, and lattice wheel seat under shed 7-2 is row's medicine passage.Top cover 1 connects the drug reservoir 3 that granule 11 is gone in storage along Fig. 1 down arrow direction.Lattice wheel 8 does not rotate at ordinary times, the top that the granule 11 in the drug reservoir 3 is intercepted at drug reservoir 3 by lattice wheel 8.Again referring to Fig. 3; When needing allotment; Make lattice take turns 8 one-directional rotation; Corresponding circularly lattice wheel seat upper shed 7-1 and the under shed 7-2 of being communicated with of the appearance medicine lattice 9 of its periphery, the granule 11 in the drug reservoir 3 just through the vertical rotation of lattice wheel 8 square from it advance row's medicine passage discharge that the medicine passage is transported to its underpart.
Obviously, lattice wheel 8 also is that a kind of standardize solution transports parts, the gram number that every kind of medicine is all demarcated every lattice in advance and held, and the accumulated dose that needs allotment is through hold adding and reaching of the medicine lattice amount of producing one by one.Holding medicine lattice 9 is exactly the pit that lattice are taken turns 8 peripheries, takes turns 8 axis directions along lattice and is of a size of the length L of holding medicine lattice 9, takes turns 8 circumferencial directions along lattice and is of a size of the width W of holding medicine lattice 9, and Fig. 4 holds medicine lattice 9 with the part displaying of lattice wheel 8.The length of holding medicine lattice 9 promptly becomes groove by pit as if the width more than or equal to lattice wheel 8, does not illustrate in addition.
Horizontal reciprocating movement just is the effect of gravity to granule and micropowder thereof with the difference of vertical one-directional rotation: the former granule and micropowder thereof all are that level is transported, and be vertical with gravity direction, and the effect of gravity is that short its is stranded in horizontal rubbing surface; Add alternation indefinite roll direction, it is fixed more to have aggravated gathering of micropowder, and the latter's granule and micropowder thereof all are to transport from top to bottom; Consistent with gravity direction, in most ways of transporting, the effect of gravity all is to help it to leave friction surface; Still see Fig. 3, lattice are taken turns the first quartile in chamber 7 in the drawings, and its bore area is recessed cylinder; Have only second quadrant that fovea superior is just arranged; But also all be to tilt descending, gravity all helps it to leave friction surface to move towards under shed 7-2, and other quadrants are the appearance medicine lattice of emptying.Visible by Fig. 5 again; The end face of lattice wheel 8 and the inner vertical walls friction of drug reservoir 3; Gravity also help the to bleed micropowder 13 in the two end face slit is discharged drug reservoirs 3; It also is row's powder passage that lattice are taken turns constriction 14 between 8 other ends and the travelling gear 15, and micropowder 13 arrives and just no longer rolled here and with the smooth and easy discharge of rotation of lattice wheel 8.
The end opening of drug reservoir 3 can be connected with the drug sack-filling device; Drug reservoir 3 suitable for reading also can with add drug storage bottle 29 and be connected (down with); As shown in Figure 6: drug reservoir 3 end openings are plugged in the plug socket 16 of drug sack-filling device along the down arrow direction, and the driven wheel 18 of the lattice wheel drive motor 17 on the plug socket 16 drives lattice through idler gear 19 and takes turns the travelling gear 15 of an end and make 8 rotations of lattice wheel, and travelling gear 15 surfaces are uniformly distributed with case sensing sign; The appearance medicine lattice quantity of its quantity dative wheel equates; The drug sack-filling device also is provided with the pick off corresponding to these sensing signs, the lattice number that turns over through these sensing sign perception, thereby control granule 11 go out dose.Said sensing sign can be Magnet or hole, and corresponding sensor then is hall device or reflective infrared device.The sensing of present embodiment is masked as Magnet 20, and pick off is a hall device 21, referring to Fig. 7.Discharge the micropowder 13 of discharging opening 3-2 and also together go to the drug sack-filling device with the granule that leaves under shed 7-2, the micropowder output, is very little, can not influence measuring accuracy.The kind of drive except above-mentioned points, some other known drive mechanism all can be used, for example, lattice wheel drive motor 17 axle heads also can be provided with worm screw, directly drive the worm gear that lattice are taken turns 8 one ends, do not give unnecessary details in addition and illustrate.The non-category of the present invention of drug sack-filling device no longer launches to detail.
Above-mentioned lattice wheel 8 in lattice wheel chamber 7 be wheel be again axle, be the simple and practical structure of a kind of ten minutes, in order to intercept granule more reliably; Also can take turns 8 two ends at lattice axle head 22 is set, the both ends of the surface in lattice wheel chamber 7 are provided with lattice wheel chamber end wall 7-4 respectively, and correspondence is provided with axis hole on it; Axle head 22 rotates and is arranged at axis hole, at this moment sludge groove 23 can be set in the axis hole end, the outlet of leaving axis hole is provided for the micropowder that gets into axis hole; Sludge groove 23 leads to outside the discharging opening 3-2, referring to Fig. 8.Further again, can helicla flute be set at the periphery of two axial ends 22, when being 8 rotations of lattice wheel, its rotation direction impel micropowder to sludge groove 23 motions, do not illustrate in addition.
Thereby the present invention adopts the lattice of vertical one-directional rotation to take turns the moving situation that can effectively improve micropowder, the fixed locking on the surface of significantly reducing friction.Through actual testing authentication, as long as granule does not make moist, even long-term continuous operation, micropowder can not gather fixed yet, transports parts and need not to clean.This also shows simultaneously, keeps the drying of granule very important.
(2) to the bonding locking of making moist and causing---still see Fig. 2; The charging aperture 3-1 of drug reservoir 3 is with top cover 1 or add drug storage bottle 29 and be threaded; Seam is provided with rubber seal 2; Bottom 5 is hinged through swivel pin 10 and is connected to the outer wall of discharging opening 3-2, and drug reservoir 3 end openings and bottom 5 seams are provided with rubber seal 6.When granule was in storage configuration, upper flap presses closer lid and with hasp 12 fastening bottoms 5, the lattice wheel just no longer is communicated with extraneous with the slit of its each parts; When opening additional granule suitable for reading; End opening still covers tightly, and said slit directly is not communicated with extraneous, so can be effectively moistureproof.Though will open bottom 5 during allotment, like Fig. 3, because of allotment time ratio resting period much shorter; One to be deployed finishing stops to arrange medicine, and bottom 5 is closed again at once, recovers airtight storage configuration; The time that lasting exposure is made moist is of short duration, so making moist during the allotment is extremely slight.
Said bottom 5 inwalls also can be provided with the resilient stake 24 of spring or rubber-like corresponding to travelling gear 15 or worm gear place; Behind hasp 12 fastening bottoms 5; Resilient stake 24 can prop up gear 15 or worm gear, and the case that makes lattice wheel 8 is positive lock during storage, referring to Fig. 9.
Perhaps, the upper and lower opening of drug reservoir all is designed to round mouth, and bottom is a dome, the suitable for reading and top cover of drug reservoir or add the drug storage whorl of bottleneck and be connected, and the end opening of drug reservoir also is threaded with bottom, and seam all is provided with rubber seal up and down, diagram in addition.
Thereby the present invention adopts the drug storage bottle of upper and lower opening and the bonding locking that air-tight manner can effectively keep away from moisture and cause thereof.
For realizing further purpose of the present invention; Notice that at first the granules in the granule 11 plaid matching wheel seat upper shed 7-1 places appearance medicine lattice 9 after drug reservoir 3 tops especially add drug storage bottle 29 have pressure; And reduce gradually along with the discharge of granule; Though force value and changing value thereof are all little, be influential for the unit weight that gets into the granule that holds medicine lattice 9.For the constant volume type metering device, the minor variations of unit weight just is enough to influence the measuring accuracy of granule.Thereby; Present embodiment is provided with taper voltage stabilizing cover 4 above lattice wheel seat upper shed 7-1 place, bear all pressure of granule of its top by it, and the granule that flows into voltage stabilizing cover 4 belows keeps constant controlling level; Thereby make the granule pressure that gets into appearance medicine lattice 9 keep stable; Significantly reduce to hold the variation of medicine lattice 9 endoparticle agent unit weights, reach the purpose that improves measuring accuracy, still see Fig. 3.The shape of said voltage stabilizing cover 4 is not limited to taper; Directly do not bear the pressure that drug reservoir 3 tops especially add the granule 11 behind the drug storage bottle 29 as long as make lattice wheel seat upper shed 7-1 place hold granules in the medicine lattice 9, be convenient to again around voltage stabilizing cover 4, flow into and hold medicine lattice 9 and get final product.Test shows: after adopting voltage stabilizing cover 4, from fully loaded to single-frame weighing removal period output the SS difference than not adopting the standard deviation of voltage stabilizing cover to reduce more than 30%.
As a kind of constant volume type metering device, the volume that needs each to hold the medicine lattice is as far as possible little, can satisfy the allotment required precision of microdosage, but when heavy dose, then has a strong impact on adjustment efficient, and dosage is big more, and efficient is just low more.For this reason, present embodiment increases a lattice wheel seat 7 ' on the foregoing description basis, and structure dative wheel seat 7 is identical; Offer the cylindrical lattice wheel chamber 7-3 ' of hollow in the lattice wheel seat 7 ' along its horizontal direction, Da Rong medicine sound of laughing wheel 8 ' is set in the lattice wheel chamber 7-3 ', form a kind of pair of lattice wheel construction; Referring to Figure 10; Wherein Da Rong medicine lattice 9 ' capacity is the several times of Xiao Rong medicine lattice 9, and two lattice wheels drive respectively, and promptly an end of lattice wheel 8 and 8 ' links through power transmission shaft and driving device respectively.During allotment, the control system of drug sack-filling device will need the major part in the ingredients amount to distribute to Da Rong medicine sound of laughing wheel 8 ', and fraction is distributed to 8, two lattice wheels of Xiao Rong medicine sound of laughing wheel and rotated simultaneously, forwards the lattice number that need change separately to and gets final product.Like this, the lattice number that each lattice wheel need change seldom just can be accomplished the allotment task in very short time.For example; Prescription needs certain medicine 23.5 gram; Da Rong medicine lattice 9 ' every lattice capacity 1.84 grams in the metering dispensing device that this flavor medicine independently is equipped with, Xiao Rong medicine lattice 9 every lattice capacity 0.13 grams, instruction lattice actuation makes Da Rong medicine sound of laughing wheel change 12 lattice after the computing of drug sack-filling device Control Computer; Xiao Rong medicine sound of laughing wheel changes 11 lattice, the row of adjustment dose: 1.84 * 12+0.13 * 11=23.51 gram.If Da Rong medicine sound of laughing wheel lattice 8 ' one Thursday, Xiao Rong medicine sound of laughing wheel 8 one Zhou Bage, then many with 1 week as long as rotated for 3 weeks respectively, and if changeed by Xiao Rong medicine sound of laughing wheel 8 entirely, just need to rotate 181 lattice, 22 weeks are many, allocate revolution and consuming timely differ very greatly different.
Moreover, the total revolution that reduces the lattice wheel has promptly reduced the friction number of times, reduces consuming time promptly having shortened the time that lasting exposure is made moist of allotment, more helps further reducing transporting the probability of parts locking.
On the concrete structure; Two lattice wheels can be provided with the betwixt mountains tandem by axle; Shown in figure 10, this moment, inner chamber was suitably strengthened in the bottom of drug reservoir 3, and voltage stabilizing cover 4 also is deformed into infundibulate thereupon; The upper opening in lattice wheel chamber is communicated with the top of drug reservoir jointly separately; The lower openings in lattice wheel chamber is communicated with the drug sack-filling device jointly, and all the other some structural elements such as voltage stabilizing cover, sludge groove, driving member, case sensing sign, bottom and resilient stake etc. all can not narrated and diagram like embodiment 1 in addition.In like manner, diaxon is set up in parallel abreast but two lattice are taken turns also, does not give unnecessary details and illustrates.
For the ease of kind identification and access addressing, the also available various known conventional methods of the outer wall of drug reservoir 3 are set up TM card or IC-card, all do not give unnecessary details and illustrate.
Two lattice wheel constructions of this metering dispensing device can increase substantially adjustment efficient, also help simultaneously further reducing transporting the probability of parts locking.
In order to adapt to the unit weight difference of variable grain, fully satisfy the allotment of the following microdosage of 0.5 gram, the structure that present embodiment adopts is: the appearance medicine lattice of said each case of aforementioned each embodiment are divided into several sections; The appearance medicine lattice that axial location is identical are measure-alike; Anticipating is the continuous whole face of cylinder of taking turns for lattice between section and the section, blocks the wherein medicine storage cavity volume of each case of mode classification change of plurality of sections appearance medicine lattice with the segmented baffle of changeable, and said segmented baffle 28 is made up of a vertical edges and a horizontal sides; The lower edge of vertical edges is a concave arc; The concave arc radius is taken turns radius corresponding to lattice, and both sides datives wheel chamber two side-to-side anastomosis suitable for reading of vertical edges place the vertical edges of segmented baffle 28 and hold the intersegmental of medicine lattice; The horizontal sides of segmented baffle 28 is blocked the appearance medicine lattice of a lattice wheel chamber end suitable for reading and below thereof, is screwed in lattice wheel seat 7.For ease of observe and drawing for purpose of brevity, segmented baffle is transparent effect and does not draw hold-down screw among the figure, down with, referring to Figure 11.Hop count is got many more, and the progression of adjusting is thin more.But it is meticulous to need not in the practical application, is provided with 2 to 3 sections usually and gets final product, and has been enough to adapt to respectively the need of large and small two-stage unit weight or large, medium and small three grades of particulate adjustment of unit weight.Situation with said three grades of adjustings is an example: most kinds are medium unit weight, segmented baffle 28 is installed blocks appearance medicine lattice 9-1, open wide two sections and hold the medicine lattice; For the kind of the big unit weight of minority, can increase another same segmented baffle 28 and block appearance medicine lattice 9-3, open wide one section and hold the medicine lattice; For the kind of the little unit weight of minority, segmented baffle then is not installed, three sections appearance medicine lattice all open wide, and do not illustrate in addition.
Segmented baffle 28 can have multiple structure, the W shape of the both sides band wing for example shown in Figure 12, both sides dative wheel seat upper shed 7-1 two side-to-side anastomosis of W shape; The bottom surface is a cancave cambered surface; The concave arc radius is taken turns radius corresponding to lattice, and both wings are fixed in lattice wheel seat 7 with screw, and is same; For drawing for purpose of brevity, do not draw hold-down screw among the figure.Differ and one enumerate.
According to the said structure deduction: also can the lattice wheel be divided into several sections; Every section all is the appearance medicine groove that open at two ends, presss from both sides the isometrical cylinder with bright finish between the lattice wheel, or changes the different lattice wheel of appearance medicine lattice volume at lattice wheel intracavity; Coaxial again or in drug reservoir bottom a plurality of lattice wheel seats are set; The lattice wheel that dative wheel chamber is rotatably assorted is set respectively in each lattice wheel seat, offers the different appearance medicine lattice of volume respectively on the periphery of lattice wheel, link through a same power transmission shaft and a driving device between the lattice wheel; Principle and on be as good as, enumerate no longer one by one and illustrate.
Segmentation of this metering dispensing device is held medicine lattice and is cooperated baffle plate to regulate, can adaptive all kind granule, also be convenient to accurately allocate microdosage.
Through above-mentioned each embodiment, this metering dispensing device is difficult for the accumulation micropowder, can prevent effectively that granule from making moist, and is difficult for locking, need not disassembly, cleaning, and adjustment precision and efficient greatly improve, and adaptive all the kind granules of ability, also are convenient to accurately allocate microdosage.
