Drug packing equipment

Technical field

The present invention relates to according to the each amount of taking of patient the technology that the drug packing equipment of tablet, medicinal powder concentrated area packing is cleaned.More particularly, the present invention relates to following technology, promptly, adopt sweeping compound, will such as, be attached to packing disk in the medicinal powder packaging facilities, draw out the medicinal powder on the medicament contact component of device, hopper, chute etc., the tablet of powdered is removed, and prevents the pollution of post-processing medicine, makes the technology of cleaning property raising.

Background technology

In the past, as shown in Figure 39, packing disk 201 had in the form of a ring, the cross section is circular-arc groove (below be called " R groove ") 202, and it is made by No. 304 corrosion-resistant steels, by lapping compound, it was ground to degree near minute surface.In addition, by with draw out device 203 in silicone rubber 204 contact, the medicinal powder that is piled up in equably on this packing disk 201 is drawn out, it is supplied with packaging facilities.In addition, if by such packing disk 201, the medicinal powder packing that will form by calcium lactate, then the particle of calcium lactate is held between the surface of the silicone rubber 204 drawn out in the device 203 and the R groove 202 in the packing disk 201, by drawing out the silicone rubber 204 in the device 203, with its compression.Consequently, as shown in Figure 40, the lactic component that comprises in the calcium lactate 205 shape that is in a liquid state floats on the surface of particle, and the lactic component 206 of this liquid state is when being involved in calcium, on the surface attached to the R groove 202 of packing disk 201, has the problem of adhering to.

The dispenser adopts not shown vacuum cleaner nozzle (with reference to the flat 09-132201 document of TOHKEMY), and the medicinal powder that object adheres to like this cleans, or by automatic rotating suction clearing apparatus, it is cleaned automatically.

In addition, in tablet package equipment, formation can be opened the structure of medicament path, the dispenser opens the medicament path termly, it is checked, the medicament that is attached on the medicament path is carried out wiping, with its cleaning (with reference to the flat 09-201399 document of TOHKEMY) by cloth, nonwoven fabrics etc.

Particularly in the occasion of medicinal powder packaging facilities, often take place because of the adsorption affinity of static, material, the effect of heat, medicament is attached to the situation on hopper, the branch packaging container etc.Have the occasion of the stronger effect of hypertoxic medicine, poison, psychotropic drug, anaesthetic etc. at the medicament of packaging, even under a spot of situation, in the medicament of the patient after will being blended into, this situation is bad.Even in medicament, very little sneak under the situation of pilin (pilin), still produce allergic reaction with the patient who pilin (pilin) class medicament is produced situations such as allergy.

Thus, have the medicament of above-mentioned stronger effect in packing after, the teacher that adjusts holds above-mentioned cleaning equipment, carefully clean, or, drop into an amount of lactose from dropping into hopper, the setting agent of adjustment starch etc., to pack with pickling agent according to a certain amount of medicament that residues on the medicament path, thus, remove medicament.

Occasion at the capsule ball, do not form powder, and residue in the medicament path, but, naked ball, wrap up in sugar-pill, compression solid ball etc. and produce powder bits because of impact, the contact of dropping, its powder bits residue in the medicament path, then, be attached to packaging the capsule ball, wrap up on sugar-pill etc., have the patient takes medicine component with hoot danger.In the occasion of pilin (pilin) class medicament, in order to prevent such danger, do not pack by shared path, only pilin (pilin) class medicament is packed individually in addition.

As above-mentioned, the residual medicine of drug packing equipment is handled by the cleaning of dispenser's manual working and is undertaken, this operation be complicated, must spend time, the operation of time.In addition, if not paying special attention to cleaning, the danger of sneaking into owing to the medicament that patient is afterwards produced strong effect increases really, so this operation is the operation of concentrating on.

The present invention proposes for above problem, problem of the present invention is to provide a kind of drug packing equipment, this drug packing equipment can alleviate dispenser's labour by simple and positively clean residual medicine in the medicament path, supplies with safe medicament to the patient.

Summary of the invention

Before the technical scheme that is used to solve above-mentioned problem was described, the principle that medicament is adhered to described.People know, if employed medicament is a pulvis in drug packing equipment, then for pulvis towards the adhering to of the wall of object, the absorption energy of object, static and liquid bridge formation power are major causes.For most medicament, the absorption energy of object and static are the main reasons of adhering to.For the medicament of a part, such as, calcium lactate, as aforementioned, if exert pressure, vibrate, then the moisture in the particle floats on the surface, and this medicament adheres on the object by this moisture, and thus, liquid bridge formation power also is the major cause of adhering to.

Refer to gravitation between the object as the absorption energy of the 1st major cause.The absorption energy of object is represented by the Hamaker constant.This Hamaker constant is big more, and then the absorption energy of object is high more, easy more absorption.For the complex class that forms by different materials, represent setting up of Hamaker constant in conjunction with theorem by following formula.

Mathematical formulae 1 $A_{12}=\sqrt{\left(A_{11}{A}_{12}\right)}$

A ₁₂: the Hamaker constant between material 1 and the material 2

A ₁₁: the Hamaker constant between material 1 and the material 1

A ₂₂: the Hamaker constant between material 2 and the material 2

In addition, the absorption energy of object is in the occasion of ball to ball, is different with ball to the occasion on plane.In the occasion of ball, because area of contact is littler to the occasion on plane than ball, so the absorption energy is less to ball.In the powder packaging facilities, because medicinal powder and medicament contact component are in ball to flat state, so the absorption energy is bigger, medicinal powder is in the environment that is attached to easily on the medicament contact component.Usually, object according to 0.4 receive the micron (nanomicron) contact, if but object have roughness of surface, then have the little characteristic of energy of adsorption quantitative change of object.Such as, the occasion of the contact between 10 microns spheroids if make both have 0.1 micron roughness, is then compared with the occasion that does not have roughness, and the absorption energy of object is reduced to 1/60000th.So in order to reduce the absorption energy of object, Hamaker constant materials with smaller must be adopted in the surface, and suitable roughness must be provided, and area of contact is reduced.

Have with particle or the uncharged situation of contact surface is irrelevant and contact electrification effect causes adheres to as the absorption of the static of the 2nd major cause, and particle or the charged static that causes of contact surface and adhering to of forming.

Adhering to of contact electrification is that this effect refers to that because of the contact potential difference between the object that is contacted, electric charge moves, and keeps stable effect because of following effect produces.In same material, owing to there is not contact potential difference, be difficult to because of contact electrification, generation is adhered to.But,,, produce contact potential difference slightly because of the difference of production place, job operation even for same material.The adhesive stress that contact electrification causes (stress of Maxwell) Pce is represented by following formula.

Mathematical formulae 2

Pce＝-(1/2)εE ²

ε: the specific inductance capacity of material

E: the electric field intensity that material had

In above-mentioned formula,, then obtain following formula if electric field E is Vc/z.

Mathematical formulae 3

Pce＝-εVc ²/2z ²

Vc: electrostatic capacity

Z: institute's contact distance between the object (usually, less than 0.4nm)

The such ball of medicinal powder packaging facilities is to the occasion of plane contact, if passage area factor ds carries out integration to aforementioned formula, then the adhesive ability of contact electrification is represented by following formula.

Mathematical formulae 4

Fce＝∫PcedsPce·S

S: area of contact (=π a ²)

,, consider that contact surface resembles rubber sphere bigger situation here,, contact radius of a circle and represent by following formula according to the Hertz theory in when contact for the material of the such softness of medicinal powder particle.

Mathematical formulae 5

a＝(3Fkd/8) ^1/3

K: elastic behavior constant

(＝(1-υ ₁ ²)/E ₁+(1-υ ₂ ²)/E ₂)

Particle diameter is big more, and the adhesive ability of contact electrification is high more.But in fact, separating force that separates because of gravity, centnifugal force, vibration etc. and 3 powers of particle diameter are proportional, and thus, comparatively speaking, particle grain size is more little, and this particle is easy more to be adhered to, and also is difficult in addition separate.

Because object is charged, produce adhering to owing to static.Situation about increasing with the increase of following carried charge is opposite, and its adhesive ability disappears when losing charged electronics.Electrostatic adhesive force between the approaching charged particle is represented by following formula.

Mathematical formulae 6

Fe＝-πσ ₁σ ₂d ²/ε _o

σ _i: surface charge density (=-q _i/ π D _Pi ²)

q _i: electric charge

D _Pi: particle diameter

D: conversion grain diameter

ε _o: the specific inductance capacity of vacuum

Because+charged right-charged, produce because the absorption of static, be the occasion of identical polarity at charged current potential, produce and repel.For the absorption with such static is suppressed at minimum degree, must reduce contact potential difference as much as possible, the conductive material that the select tape electric potential moves easily.

Be adsorbed as following phenomenon as what the liquid bridge formation power of the 3rd major cause produced, this phenomenon refers on the outside of pulvis particle, forms the film of moisture, and film and film adsorb because of the surface tension of moisture.Because moisture is micro-, so usually, the medicinal powder that is used for the medicinal powder packaging facilities does not develop into the absorption that liquid bridge formation power produces.But the machinery of the compression during owing to medicament packing, transmission, slip, vibration etc. produces the absorption that liquid bridge formation power causes.That is, if to medicinal powder applied pressure or vibration effect for a long time, then the moisture in the medicinal powder particle flows to the outside, forms film, produces the absorption that body bridge formation power causes.In order to suppress the absorption of this liquid bridge formation power, also consider the contact surface of medicament contact component is refused water treatment.

If the measure of taking adhering at pulvis is summarized, then following measure is considered in the absorption of the absorption energy of object relatively.

(1), covers the pulvis contact surface by the less material of Hamaker constant.

(2) according to the Hamaker constant in conjunction with theorem, select the pulvis contact surface.

(3), set the roughness that is fit to the medicinal powder contact surface.

In addition, at the absorption that static causes, consider to adopt following measure.

(1) the medicament contact surface is carried out surface treatment or selects material, reduce contact potential difference.

(2) make the harder or relative pulvis grain diameter in surface make it thicker, reduce area of contact.

(3) suppress charged, promote movement of electric charges.

At the absorption that liquid bridge formation power causes, consider to adopt following measure.

(1) by the surface treatment of medicinal powder contact surface, improves and refuse the water effect.

According to these situations, in order to remove residual medicine, between accompanying particle and sweeping compound, establish the bigger relation of Hamaker constant, the deadweight of adhering to medicament is increased, even in this case, judge that still residual medicine reduces.

The specific embodiment

A. the surface treatment of medicament contact component

1. input hopper

Input hopper 1 shown in Figure 1 is the chamfered edge taper, and the top that it is arranged at vibra feeder 2 has the memory function of quantitative dispatch medicament.Portion stores medicament within it, if by vibra feeder 2, send this medicament, then micro powder is attached on the inwall of above-mentioned input hopper 1.Such as, as shown in Figure 2, if medicament is an aspirin, then above-mentioned input hopper 1 is existing corrosion-resistant steel, then by the vibration of vibra feeder 2, produces static, but, because above-mentioned input hopper 1, vibrating feed tank 3 are connected to chassiss, so usually, charged (Coulomb force) that static causes takes place hardly for it.But, because aspirin is the crystal that the cuboid by 0.2～0.8mm forms, so the planar portions of this crystal, be attached on the inwall of input hopper 1 resembling under the state of laying bricks fitly side by side, be created in the firm adhesive ability that does not drop under the knocking slightly.

This major cause of adhering to is the aspectant stronger absorption energy that causes that contacts between aspirin and the stainless input hopper 1.Because dropping into hopper 1 is metal, so the value of Hamaker constant is bigger, the absorption energy is also bigger.In addition, because aspirin is a crystal, so its planar portions also is the stronger reason of adhesive ability with the planar portions effect to stainless input hopper 1 largely.Such as, if make to drop into hopper 1, carry out same test by polycarbonate because the value of the Hamaker constant of resin system material is less, thus aspirin be attached on the wall power a little less than, understand because of deadweight and drop.In addition, because resinous material is an insulating material, so the charged current potential ground connection that vibration is caused.But, even be higher than at charged current potential under the situation of stainless input hopper 1, adhering to of the charged aspirin that causes still do not appear.Like this, decidable, aspirin are attached to the absorption energy that the major cause on the stainless input hopper 1 is an object.

Drop into the occasion that hopper 1 is formed by resin, primary problem tackles static (Coulomb force).In the occasion of drug packing equipment, be necessary for the type of the multiple medicament of reply.The material that drops into hopper 1 forms by using the material of sneaking into conductive material in resin, thus, and to improve to a certain degree because the charged tack of the medicament of static.But,,, still less to the effect of the medicament of micro powder class even then under the situation that is resinous material if the contact potential that drops between hopper 1 and the medicament is higher.Because the deadweight of this micro powder class medicament is lighter, so can't drop by knocking slightly.At particle diameter is the occasion of 10 μ m, and the energy that is used to make the micro powder of such medicament to drop is necessary for 10,000 times power of this particle weight, and 3 powers of separatory power and particle diameter are proportional, and thus, particle diameter is more little, and it can't drop by knocking slightly more.In addition, noise is also violent.Promptly, set following condition, even this condition refers to select make under the situation that above-mentioned micro powder class medicament drops by knocking, the value of Hamaker constant is materials with smaller still, and in this case, contact potential difference is still less between multiple medicament, seeks overall counter-measure, so that by knocking slightly, this medicament just drops.

Analysis through the inventor is learnt, by adopting the composite material that describes below on the surface of dropping into hopper 1, can suppress the absorption energy of object, aspect the measure of opposing static (Coulomb force), is that actv. is handled.

(composite material 1)

The composite material 1 that adopt on the surface of input hopper 1 is such, forms by aluminium and drops into hopper 1, in its surface, forms fire coat, makes resin infiltrate in the crack that produces in this fire coat or the inside of porous matter, covers this surface.

In this surface treatment, as shown in Figure 4, on aluminum mother plate 4, form the passivation aluminium lamination 5 of thickness in the scope of 5～100 μ m, teflon resin 7 is infiltrated in the hole 6 of the porous matter part that produces in passivation aluminium film forming process.

Perhaps,, passivation aluminium lamination 5 is heated to 300～400 ℃,,,, produces crack 8, teflon resin 7 is infiltrated in the hole 6 of this crack 8 and porous matter portion on the surface of passivation aluminium lamination 5 by these measures etc. then to its rapid cooling as shown in Figure 5.

Aluminum mother plate 4 is defined in aluminium, or aluminum alloy materials, and die casting has film formation tendency out of order.The surface of such processing is the dispersion complex film of aluminium oxide and fluorocarbon resin, has corresponding superperformance.Such as, for the value of Hamaker constant, aluminium oxide is 15.5, and resin is in 3.2～12.3 scope, and these values are than 49.2 of corrosion-resistant steel (Fe/Ni alloy) low values.

The shaping of metal solder is also considered in the shaping of aluminum mother plate 4, still, if the changes in material of weld part, if carry out surface treatment, owing to produce color spot, so, preferably do not adopt this mode from the product property aspect.For this reason, from packing quality aspect, preferably adopt the shaping of rotary pressing processing, deep draw, dewax fusible pattern molding casting method, die-casting technique, casting etc., but, for wherein dewax fusible pattern molding casting method, die-casting technique, casting, as aforesaid, the quality of passivation aluminium is not so well.

As the preferred forming process of aluminium parts 4, such as, make as shown in Fig. 6 (a), by spinning roller 9, be the coniform goods that carry out rotary pressing processing,, pass through punch process as shown in Fig. 6 (b), be pyramid-shaped, as shown in Fig. 6 (c), cut unnecessary part, residue handle portion 10, as shown in Fig. 6 (d), handle portion 10 is carried out bending machining.Because from need not to adopt the aspect of abradant material, the forming efficiency of this forming process is good, so can suppress cost.

Mention in front,, necessarily require roughness of surface to a certain degree in order to suppress adhering to of medicament, still, if since roughness of surface greater than 12 μ m, then showy at the residual medicament of slot part, so the best surfaces roughness is less than 12 μ m.

In the hopper that has been shaped, having outside, pellicle forms the electrode that extra electric field is used in the liquid.This electrode is fixed in the position of the admittance that does not hinder medicinal powder, and it is supported on this position by pressing plate.Owing to also can after surface treatment, the hopper that is fixed with electrode be carried out fine limit work handle, so the fine limit work quality improves.Because in the occasion by the pressing plate supporting, in any case, can not carry out surface treatment at clamp portion, the surface treatment of the relative black of this part is white in color, very eye-catching, pulvis adheres to easily.

Hopper is pyramidal shape, wherein, the top broad, the below is narrower.At the peripheral part of hopper, welding is used for hopper is installed on supporting member 11 on the device.This supporting member 11 also can pass through adhesive securement, so that replace the mode of welding.If lining cement adopts the type of not peeling off in treating process, then be preferably in the surface-treated process, processing gallantly, as required, according to aforesaid Fig. 6 step, installing component.

Here, according to the diagram of circuit of Fig. 7, the basic procedure that passivation aluminium is handled is described.

When accepting passivation aluminium and handle, at first,, carry out whether problematic inspection to the material of processing element.Such as, also to the adhering to of adhesive tape (tape), coating etc., the Sorting Materials of the copper alloy that the film formed processing method of appearance is different, having or not etc. of defective checked.

For the up-to-standard processing material of material acceptace inspection,,,, passivation aluminium is set according to the mode that can suitably handle being used to make electric current flow through the arc-spark stand of goods in the mounting bracket step.

If mounting bracket finishes, make and handle material at each support, be soaked in the ungrease treatment groove, carry out ungrease treatment.For the kind of degreasing, main division has or not the etch degreasing, goes delustring pool degreasing, electrode degreasing.At every kind of degreasing, conditioning fluid is different, still, mainly adopts the liquid of alkali system, such as, sodium hydroxide system, neutrality or organic system purging medium account for major part.Acid degreaser adopts fluoric acid, nitric acid, hydrochloric acid.Degreasing time is followed conditioning fluid, processing method and difference, and still, in the occasion of going delustring pool degreasing, this time is in 1～3 minute scope.After degreasing finishes, will handle material and be soaked in the rinsing bowl, degreaser is cleaned.

Then, in order to remove the fire coat (pellicle outside the thin natural passivation aluminium) that on the passivation aluminium surface of handling material, forms naturally, carry out corrosion treatment.For this corrosion treatment, the main division has electrolytic polishing method and chemical grinding method.In the occasion of electrolytic polishing method, be soaked in the liquid of sulfuric acid, phosphoric acid handling material, carry out electrolytic polishing.In the occasion of chemical grinding, adopt phosphoric acid, nitric acid, acetic acid etc.Occasion adopting phosphoric acid is soaked in inorganic agent in the conditioning fluid of temperature in 80～100 ℃ scope, reaches 6～120 seconds, in rinsing bowl, it is cleaned.Then, corresponding to the kind of corrosion treatment, necessarily require to carry out neutralization procedure, water-washing step.

If these pre-treatment steps finish, then carry out passivation aluminium treatment step.For the outer pellicle of passivation aluminium, follow kind, the formation speed of Treatment Solution, the roughness of porous matter changes, and the color of film also changes.

In the occasion that forms hard passivation aluminium, adopt the bath liquid of oxalic acid system, sulfuric acid system.Occasion in oxalic acid system flows through 100～2000A/m ²Electric current, carry out greater than 60 minutes processing, form outer pellicle.At this moment, in order to reduce the density of porous matter, the temperature of bath liquid remained in 5～10 ℃ the scope.If the temperature of bath liquid is too high, then the porous qualitative change is thick, and superficial hardness reduces, and can't form hard passivation aluminium.Owing to follow the growth of outer pellicle, surface portion is insulated, current value reduces, so can pass through current value, confirms the situation of outer pellicle.

If the outer pellicle of passivation aluminium is finished, then take out from bath, in rinsing bowl, it is cleaned.At this moment, if clean insufficiently, then produce the color spot be called " ablation ".

Then, infiltrate processing, so long as can infiltrate the material in the porous matter part that on pellicle outside passivation aluminium, produces, any material can, omit the description that the non-tack as the medicament of purpose of the present invention is not had the painted infiltration of effect.

Such as, infiltrating the occasion of PTFE, as shown in Figure 10, will pass through fluorated solvent etc., the liquid fluorine lubrication solution has been carried out dilution and the solution of formation is accommodated in the container 12, will handle in the solvent that material 1 ' is soaked in this container 12.Then, this container 12 is sunken in the water of super sonic bath 13, it is positioned on the netted platform 15 on the oscillator 14.At this moment, in order to promote this infiltration, apply vibration by ultrasonic generator 16.Then, handle the washing of material 1 ', as required, handle, blow steam, carry out hot water wash, then, it is carried out drying, remove support, check as sealing of hole.

In the occasion of infiltrating metallic ion, adopt same step equally, still, the occasion infiltrating silver ion at cathode side set handling material, is provided with silver electrode in anode-side.

Infiltration step to fluorine system, metal system is described above, still, also can infiltrate acrylic resin, epoxy resin resin.

Like this, in passivation aluminium, infiltrate the surface of processing material of PTFE as shown in Figure 8, by passivation aluminium Al ₂O ₃Form with the PTFE resin.For the adhesive ability of pharmacy particle, in the bigger occasion of the influence of contact potential difference, the relation of passivation aluminium＞PTFE is set up, otherwise in the bigger occasion of influence of static (Coulomb force), the relation of passivation aluminium＜PTFE is set up.

Here, in the bigger occasion of the cohesiveness of medicament, because the value of the particle diameter dx that produces because of cohesion is bigger, so by knocking, vibrating, its easy and sur-face peeling slightly.Relative therewith, in the less occasion of the cohesiveness of medicament, the size of the diameter d of pharmacy particle has considerable influence to the effect of peeling off of knocking, vibrating, certainly, if the diameter d of pharmacy particle is less, then since peel off desiredly knock, 3 powers of the diameter d of vibratory force and pharmacy particle are proportional, so be difficult to drop.

If consider the bigger occasion of influence of contact potential difference, because adhesive ability for pharmacy particle, the relation of passivation aluminium＞PTFE is set up, so only be attached to the medicament in the lower PTFE zone of contact resistance to certain percussion power, peel off effect, but can stay the medicament that is attached to the higher passivation aluminium zones of contact resistance.That is, form the possibility of residual medicine higher for being attached to the medicament of passivation aluminium zones.In addition, in the bigger occasion of the cohesiveness of this medicament, because it is big that the value of the particle diameter dx that produces because of cohesion becomes, so opposite with the situation of the further increase of the effect of peeling off of relative certain vibration, the medicament of PTFE area peripheral edge (being attached to medicament on the passivation aluminium zones) also condenses.Here, if the effect of peeling off is got the upper hand, also peel off because of cohesiveness owing to be attached to the medicament of passivation aluminium zones, so compare with aforesaid condition, the amount of residual medicine reduces.Consequently, the adhesive ability of peeling off the more weak passivation aluminium zones of effect effectively reduces.

Consider the bigger occasion of influence of static (Coulomb force) below, the above-mentioned effect of peeling off is opposite.Because passivation aluminium is difficult to be subjected to the influence of static, the situation that is attached to the medicament on the PTFR zone that is subjected to electrostatic influence easily is opposite with leaving, and the medicament that is attached to the passivation aluminium zones is under certain vibration, and effect is peeled off in performance.Thus, produce residual medicine in the PTFE zone easily.In this occasion,,, be involved in equally, it is peeled off so also will be attached to the medicament in PTFE zone because the medicament that is attached to the passivation aluminium zones is easy to generate the effect of peeling off under certain vibration if the cohesiveness of medicament is bigger.Consequently, the residual dose of single-piece reduces.

For the processing material that in passivation aluminium, infiltrates metallic ion, can think equally in the bigger occasion of the influence of contact potential difference, and the bigger occasion of influence of static (Coulomb force), 2 kinds of surface material mutual actions, various medicaments is said on the whole relatively, and residual dose is reduced.

Like this, the hopper that infiltrates fluorine resin, metallic ion in passivation aluminium can peel off the medicament that temporarily adheres to easily by exterior stress is provided.Should " exterior stress " refer to, apply and knock, vibrate hopper, or the suction process of employing dust collecting fan etc.

In addition, as the material that penetrates in the passivation aluminium treated side, will specifically describe by the composite material 2 in the back, still, it also can be, such as, the metallic material of copper, gold, silver, nickel, tin, titanium etc.Adhere in the measure of preventing at medicament, silver, titanium oxide is effective especially.Infiltrate material for these, can think, as aforesaid, in the bigger occasion of the influence of contact potential difference, and the bigger occasion of influence of static (Coulomb force), 2 kinds of surface material mutual actions, multiple relatively medicament on the whole, reduces residual dose.

When carrying out aforesaid surface treatment, should be noted that electrode is arranged at and irrelevant position of adhering to of medicament.

In addition, common passivation aluminium no matter, hard passivation aluminium all can infiltrate processing.

The resin that infiltrates also can be polyethylene etc. except PTFE, PFA, generally adopt PTFE.The infiltration method also can be corresponding to resin material, and has corresponding mode.

In the occasion of infiltrating resin, preferably adopt the mode of not extracting out from the hole that is formed on the basal plane according to resin, carry out the mode of hole encapsulation process, stable so that quality keeps chronically.

By by aluminium oxide Al ₂O ₃Basal plane and the resin that penetrates in the hole of this basal plane, such as, the composite surface of the face of fluorocarbon resin, the contact potential difference between pulvis and the face diminishes, thus, the non-tack of the pulvis in the medicament improves.

Basically, following situation becomes focus, and this situation refers to the non-attachment characteristic for pulvis, by aluminium oxide Al ₂O ₃The composite surface that forms of the face of basal plane and resin in the contact potential difference of relative pulvis be bigger, still less.The non-attachment characteristic that is not fluorocarbon resin directly exerts an influence, and the non-tack of pulvis is improved.If the face of fluorocarbon resin is with respect to aluminium oxide Al ₂O ₃The ratio of basal plane improve, owing to being subjected to significantly because of contact the influence of the contact potential difference that produces with fluorine, so the non-tack variation of pulvis.

In the general occasion that adopts homogenous material, have the tendency that the metallo-contact potential difference rises, still, wherein the contact potential difference of aluminium oxide is less, by oxidation, contact potential difference can be suppressed to littler degree.

Table 1

Contact potential difference

Oxide based material	6～15
		Metal	15～50
Resin	3.2～12.3

For resin, general, most cases is that contact potential difference is lower, and still, insulativity is higher, otherwise pulvis is in that contact is charged after leaving repeatedly, and because of the effect of this influence, pulvis adheres to.

Aluminium oxide Al ₂O ₃Basal plane be insulator, still, subsurface middle level is aluminium oxide or aluminium oxide alloy, satisfactory electrical conductivity is higher.Thus, handle, do not produce because of charged the situation that pulvis adheres to by the passivation aluminium before and after the thickness 50 μ m.Because the particle of resin is very little, so the static that produces between the resin that has infiltrated does not produce bigger electrostatic capacity.Thus, even hypothesis under charged situation, because electronics moving at thin outer pellicle inner face, so in infiltration the passivation calorize of resin is arranged, does not have higher static.

(composite material 2)

Then, the composite material 2 that is used to drop into the surface of hopper 1 infiltrates material as the metallo-of the effect of the non-tack that can confirm pulvis, adopts titanium oxide and silver ion, and it is penetrated in the alumina surface.

In order in infiltrating step, to infiltrate silver ion, silver is positioned in the treatment trough as anode plate, electric current is flow through, silver ion is dissolved in infiltrates in the Treatment Solution, to put in this solution by the processing material that passivation aluminium is handled, add cathode voltage, at this moment, infiltrate silver ion in the hole that in the passivation aluminium lamination, produces.For infiltration the surface of silver ion is arranged, the influence of material has bigger effect to the quality of the non-tack of pulvis.Passivation aluminium is handled through hard passivation aluminium, and the hole that is formed at the surface is according to degree formation more closely.

The better material of non-attachment characteristic of pulvis is to penetrate into A1100-0 material (annealed material), and the material of A2017-0 material (annealed material) has the identical effect of material of infiltrating above-mentioned PTFE resin.Be 2017 materials equally, for heat treatment product T5, T6 (high temperature cools off the artificial age-hardening suddenly to be handled, and after the melt processing, the artificial age-hardening handles) or F (the former state goods that produce), opposite non-attachment characteristic variation.In addition, the non-attachment characteristic of A5052-0 material, 6061-0 material is all bad.Can think that its reason is: be subjected to the influence of alloy auxiliary material largely.Such as, occasion at the A2017 material, it is believed that: because in passivation aluminium treating process, the Cu metal is when forming ion, form passivation aluminium, so apparent condition is also chapped the quantity in hole, density, size variation easily, if infiltrate silver, then the distribution proportion of the silver of expanding on the surface is realized increase and decrease.If the ratio of silver increases, then the contact potential difference on surface rises, and adheres to pulvis.

For the material that infiltrates titanium oxide, because the contact potential difference of titanium oxide was lower originally, so be difficult to be subjected to the influence of the character of material.

Know, like this,, adopted the contact potential difference composite material of lower material originally, have effect by use in order to improve the non-attachment characteristic of pulvis.In addition, it is believed that the electric conductivity that has immersed the material passivation aluminium surface of silver ion improves, the charged current potential step-down of static also improves the tack owing to static, and consequently, the non-attachment characteristic of pulvis improves.

In the occasion of infiltrating titanium oxide, silver ion, be preferably in and carry out the hole encapsulation process after infiltration is handled equally, it can not be extracted out from the hole that is formed on the basal plane, stable so that quality keeps chronically.

Also can in the packing hopper 18 of packing department shown in Figure 9 17, use by the surface treatment that above-described composite material 1, composite material 2 form.Because packing hopper 18 constitutes in the following manner, this mode is: because of the influence of the dry air of 19 heating of the warm-up mill by packing department 17, be easy to generate static, and simultaneously at the in-to-in that medicinal powder is stored in packing hopper 18 temporarily, it is supplied with packing department 17, so the small medicament of particle is attached to the inside of packing hopper 18 easily.But by also packing hopper 18 being carried out aforesaid surface treatment, the amount that is attached to the small medicament of in-to-in particle of packing hopper 18 reduces.Residue under the in-to-in situation of packing hopper 18 even suppose small medicament, still can nearly all medicament be dropped by the knocking of the knocking device that during preparing, carries out.

As the further mode that improves of the non-tack of the medicament that makes this packing hopper 18, it is believed that, ultrasonic oscillator is fixed on the packing hopper 18, the mode that makes its vibration is an actv., but, if material is an aluminium, the problem that then exists the vibration resonance efficient of ultrasonic oscillator to reduce by half.So, if as shown in Fig. 9 (a), on the lateral surface of packing hopper 18, attach stainless steel sheet 20, oscillating action spread in whole packing hopper 18, then the vibration resonance efficient of ultrasonic oscillator 21 returns to certain certain value.But, to compare with the occasion on directly being attached to the corrosion-resistant steel hopper, the vibration resonance efficient of ultrasonic oscillator 21 is bad.So, above-mentioned packing hopper 18 adopts the type that forms by following method, this method is: aluminium oxide ceramics is carried out molded, it is carried out roasting, then, infiltrate fluorine, on the lateral surface of these goods, direct mount ultrasonic oscillator 21, at this moment, though can expect that cost is higher, the hopper of characteristic good.

Because in above-mentioned packing hopper 18, base material is metal, pottery, thus can be because of near warm-up mill 19 heats do not melt, or be not easy the demoulding, and do not resemble and burn the resin moulded parts.But if because of the heat of warm-up mill 13, the temperature of packing hopper 18 rises to 60 ℃, then is detained or the temperature that is slipped to the in-to-in medicinal powder of packing hopper 18 also rises, and is attached to easily on the inside face of packing hopper 18.Particularly digoxin preparation, benzathine penicillin G, Off エ バ ノ-Le, stone first south (madical) are adhered to easily.So, also can be as shown in Fig. 9 (b), outside at this packing hopper 18, heating pipe 22 is set, it is positioned at the bottom of this packing hopper 18 according to heat absorbing side, and the heat release side is positioned at the mode at the top of this packing hopper 18 and installs, and in the heat release side radiating gill (heat sink) is installed, and this radiating gill is cooled off.Perhaps, also can near this packing hopper 18, fan 24 be set,, dry, this packing hopper 18 is cooled off along the radiating gill 25 that is arranged on this packing hopper 18 as shown in Fig. 9 (c).

Because the value of the contact potential difference of oxide material is less basically, so preferably adopt aluminium, magnesium, the titanium that forms metallic oxide easily.

If consider processing, material behavior, aluminium is expected to prevent adhering to of medicament, also can suppress productive costs by hopper being carried out mode such as deep draw.

In addition, rotary pressing processing also is expected to suppress productive costs.

2. vibrating feed tank

Vibrating feed tank 3 generally is processing like this, and electrolytic polishing is carried out on stainless surface, is ground-glass appearance, and fine limit work is carried out on its surface.In such groove 3, as shown in Figure 11, confirming has the surface of calcium lactate at groove 3, leaves the phenomenon of gushet.If produce so residual medicine, then the medicament that the patient took lacks than the actual amount that drops into.Such phenomenon is called " the medicament percent recovery of packaging facilities ".Usually, the medicament of powdery type, its percent recovery is poor more, and rare have when for the medicament of particle etc., and because of factors such as beating in distributing, the percent recovery descends.

In order to solve the phenomenon that gushet is arranged at the remained on surface of above-mentioned groove 3, basically, can carry out non-tack to the surface and handle, still just opposite with regard to the situation on surface, non-tack variation.

Such as, in the occasion of coating, in coating agent, mix the PTFE resin, in addition, the pulvis of hybrid ceramic etc., strengthening surface hardness.If handle by such coating agent, then as shown in Figure 13, tiny pulvis particle enters into the jog on the surface that produces because of spraying plating, is attached to thinly on the whole, non-attachment characteristic variation.

In addition, this time charged by the vibration realizing of vibra feeder because of the influence of static if mix the PTFE resin in large quantities, the generation pulvis is attached to phenomenon on the whole thinly.The incorporation rate of PTFE resin is preferably in 15～30% the scope.For the coating thickness,, then little by little be subjected to the influence of static easily if surpass 30 μ m.Its reason is: even be under the metallo-situation at matrix, the charged electronics of coated surfaces still is difficult to move by base material.

For the state smoothing ground to coated surfaces carries out fine limit work, best, apply by screen printing, but, if the viscosity of coating material can be suppressed at than low degree, then equally for the occasion of the coating of spraying plating, also have effect, but it should be noted that the thickness of film is not excessive.Such as, in the mode that applies by printing, have the color steel sheet that adds fluorocarbon resin.

Usually, such material is as the dressing of a surface plate of gas furnace etc., still, if adopt this material groove, then judge eliminate the calcium lactate that takes place in the past remained on surface at groove be the mesh-shape decorative pattern medicament phenomenon aspect, cleaning property is good.

The composition of this steel plate is such, as shown in Figure 12, plate golding aluminium zinc alloy is carried out on the surface of steel plate 31 handle, then, thereon, carry out the processing of conversion coating 33, on the conversion coating 33 on surface, insert and put priming paint 34, with screen printing the steel plate of fluor resin coating 35, under the temperature about 200 ℃, carry out roasting and constitute, in the lower-cost alkide resin coating 36 of inner face screen printing.

In addition, because the processing that the color steel sheet of such infiltration fluorocarbon resin can not weld etc. then is being used for the occasion of groove, be connected with oscillator institutional, section gets rusty etc. can the formation problem.So, form groove by deep draw, as shown in Figure 14, with common cut-out portion recurvation, form curled portion 37, thus, section is not exposed on the surface, and by bending machining, form the ear 38 that is connected usefulness with the mechanicalness of oscillator, above-mentioned these problems can be eliminated.

The surface treatment of groove 3 also considers to make fluorocarbon resin to penetrate into processing in the passivation aluminium.

The same occasion of handling in such infiltration can solve and is the mesh-shape decorative pattern, and medicament residues in the phenomenon on the surface of groove 3, still, also has the amount of following vibration, medicament, and medicament is certain mesh-shape decorative pattern and the occasion of residual phenomenon.But, can clean easily by dust collecting fan etc.

Why making fluorocarbon resin penetrate into the occasion of the processing of passivation aluminium resin, can produce the amount of following vibration, medicament, medicament is the mesh-shape decorative pattern and residual phenomenon, can think that its reason is relevant with the smoothness on surface, still, does not verify reason at present.

Make fluorocarbon resin penetrate into the occasion of the processing of passivation aluminium, width has numerous about 2～5 μ m, the degree of depth shallow slightly groove in the scope of 1～3 μ m on the surface.In addition, by the resonance of groove 3, at the surface element of groove 3, vibrative strong and weak zone, the lactic acid of the trace that comprises in the calcium lactate on the groove 3 liquefies because of vibration, and film floats on the surface of calcium lactate pulvis particle in the mode that spreads out.If from such situation supposition, then think: the countless groove on above-mentioned surface is compared with planar portions, the adhewsive action of calcium lactate increases, and because of the amount of vibration, medicament, on treated side, adheres to calcium lactate or non-cohesive calcium lactate partly.

Like this, owing to be present in the effect of the lip-deep countless groove of groove 3, what make non-attachment characteristic variation, if but clean by dust collecting fan etc., then can be easily by the attraction mode, removal is the residual medicament of mesh-shape decorative pattern.

Thus,, can the groove cleaning nozzle 39 of cleaning equipment be moved as shown in Figure 15, can be by preventing to pollute with the surface-treated Overlay.In addition, if make this groove cleaning nozzle 39 move to the lens component of the sensor 39a that drops, then also can eliminate following problem in the past, promptly, micro powder is attached on the sensor 39a that drops, and is in the state that can not detect, and makes no matter when all can not move from distributing operation.

In order to make this groove cleaning nozzle 39 actions, necessarily require action step as shown in Figure 16.

At first, finish fully, then drop into hopper 1 and return provisionally from groove 3 if supply with action.Then, the dust collecting fan in the cleaning equipment begins suction, and then this groove cleaning nozzle 39 descends, and contacts with the surface of groove 3.The contact part of this groove cleaning nozzle 39 can adopt the type of the softness of CR sponge, brush etc.In addition, above-mentioned groove cleaning nozzle 39 moves on the surface of groove, if not shown sensor arrives its terminal part, then as-is condition makes in opposite direction to move and turns back.Then, if detect the leading section of groove, then above-mentioned groove cleaning nozzle 39 as-is conditions clean, and the position until the lens of the sensor 39a that drops turns back to the fixed position again.Cleaning action at last from the leading section of groove, be up to the reason of the lens of the sensor 39a that drops: prevent that the medicament that is attached to sponge, brushes from being attracted, and residue in the situation on the groove 3.Be positioned at the fixed position if detect above-mentioned groove cleaning nozzle 39, or, then will drop into hopper 1 and turn back to the fixed position near in the process of this fixed position.Be positioned at the fixed position if detect above-mentioned groove cleaning nozzle 39 with input hopper 1, then produce the received signal of next processing.If by this signal, expression can be carried out next prescription and handles, or makes the wait feeding device, waits for and drops into medicament or operation such as drop into automatically.

In infiltration the occasion of the color steel sheet of fluorocarbon resin is arranged, because the treatment surface characteristic is very good, by the mask printing, be suppressed to the thickness about 20 μ m, apply, so flatness is higher, the distribution of the PTFE that exposes from the teeth outwards is certain.Thus, even the stronger position of vibration in the strong and weak zone of the vibration on the surface of the groove 3 that the resonance because of groove 3 produces still can guarantee non-attachment characteristic, calcium lactate can not be the mesh-shape decorative pattern and be residual.

Adopt fluorocarbon resin to infiltrate the occasion of color steel sheet on the surface of groove 3, manufacturing process is defined in deep draw, and in the occasion of supplying with by small lot, the cost of mould etc. rises, and this is unpractical.So,, be scattered in lip-deep amount more than 15% according to about as processing corresponding to such small lot, fluorocarbon resin is blended in the lower coating material of viscosity,, it is carried out spraying plating according to the degree about 20 μ m, under 220 ℃ temperature, it is carried out roasting.Thus, the surface finish of the non-attachment characteristic that fluorocarbon resin is arranged is had both on its surface, to infiltrate color steel sheet identical with aforesaid fluorocarbon resin, do not produce to be netted decorative pattern and residual medicament.

In addition; the characteristic that fluorocarbon resin infiltrates coating material is mainly by the condition control of the auxiliary material that are used to protect coating material, superficial hardness etc.; but, preferably make the surface distribution ratio of surface smoothness and non-attachment characteristic material basically, and keep balance between the charging property of generation of static electricity.

3. draw out device

As shown in Figure 180, draw out device 40 by following component set-up, these following parts comprise round rubber dish 41, the medicinal powder that this round rubber dish 41 will be piled up on the packing disk impales, and it is swept together; Rubber is drawn plate 42, and it is used for the medicinal powder of sweeping is together drawn out packing department 17 (with reference to Fig. 9); Rubber spacer block 43, the medicament that these rubber spacer block 43 guiding are swept together makes it not scattered in the zone of next part.

These parts were to add silicone rubber to carry out roasting and use in corrosion-resistant steel in the past, still, had pulvis and were attached to problem on the stainless steel parts.Thus, in order to remove the medicament that is attached on corrosion-resistant steel, the silicone rubber, the effect of the mode of removing by sheet rubber, brush etc. is not so good, and the dispenser adopts dust collecting fan, cleans manually.

In occasion of the present invention, as shown in Figure 17, the 2 blocks of plectanes 44,45 with holes that round rubber dish 41 is made by aluminum and the silicone rubber 46 of ring-type constitute.In round rubber dish 41, with the circular protrusion 47 that is formed at wherein on the edge of the hole 44a in the plectane 44, be pressed among the hole 45a of another plectane 45, silicone rubber 46 is clamped between roasting face 44b, the 45b that is on the outer peripheral edges that conical surface-shaped is formed at 2 blocks of plectanes 44,45.In the past, in order to keep the intensity of roasting of silicone rubber, unnecessary roasting position is set, but, if silicone rubber to expose area more, then adhering to of medicament also becomes many, thus, according to the present invention, only expose at the diametric consumption position of the width of silicone rubber 46.In addition, passivation aluminium is carried out on the surface of 2 plectanes 44,45 of being formed by aluminium handle, polytetrafluoroethylene is penetrated in this passivation aluminium lamination.

If carry out such surface treatment, because the cohesive resistance of medicament reduces, so as shown in Figure 180, only approaching by the nozzle 48 that makes dust collecting fan, the present invention can be easily with the medicament removal of having adhered to.That is, at the origin position of drawing out device the nozzle 48 of dust collecting fan is set, finishes if draw out step, the medicament of then can be automatically round rubber dish 41, rubber being drawn the surface of plate 42 and rubber spacing block 43 cleans.

The reason that the nozzle 48 of dust collecting fan is set is: by dropping of knocking bigger particle is had effect, the medicinal powder molecule to the smoke screen shape that produces in the action of drawing out device 40 does not have effect fully, has problems in the processing after medicament is dropped.

If draw out the nozzle 48 of device 40 near dust collecting fan, then the nozzle 48 of dust collecting fan begins suction, simultaneously, draws out the device revolution.Preferably when rubber is drawn plate 42 near the pump orifice of vacuum cleaner nozzle 48, suction inlet leaves repeatedly, approaching action, so that can be swept into the boss portion of drawing out device 40.

In addition,, brush 49 is set near the nozzle 48 of dust collecting fan, then cleans effect and improve if in order to improve the cleaning effect.

This brush 49 also can be acrylic fiber etc. to plant hair right, also can adopt the CR sponge.In addition, for fear of sneaking into foreign matter, the position that is provided with of brushing the cleaner of 49 grades is preferably the position that the end face with the packing disk leaves.

In occasion of the present invention, the surface treatment of fluorocarbon resin is infiltrated in employing in aluminium, but, also can be according to condition, employing is blended into fluorocarbon resin in the surface of steel plate with coating, and the goods that form are thus carried out the mask printing, the type that surface accuracy is improved, so long as the type that the contact potential difference of employing and medicament diminishes is then no problem.

4.V shape rises the bucket disk

In the past, V-arrangement rises the bucket disk and adopts corrosion-resistant steel, still, and owing to medicament is attached on the inlet inner face, so most medicament for can't in the packing treatment step, reclaiming.In order to improve this percent recovery, adopt and scrape pocket knife, the medicament seldom that has adhered to is dropped on the packing disk.In addition, because when on-off action, disk in the outer shroud damage is so if use all the year round, then have the problem that the medicament adhesion amount also increases.

Thus, as shown in Figure 19, it is the aluminum alloy A5052 material of 3mm that the interior ring 51 that V-arrangement rises bucket disk 50 adopts thickness, is carrying out after hard passivation aluminium handles, and it is carried out fluorine infiltrate and handle, and thus, improves the non-tack of medicament.In addition, the outer shroud 52 employing thickness that V-arrangement rises bucket disk 50 are the aluminum alloy A5052 material of 1mm, after carrying out the processing of hard passivation aluminium or common passivation aluminium, it is carried out the fluorine immersion handle.The shaping of these parts is processed as spinning or punching press.

Because by like this, V-arrangement is risen the bucket disk process, when the on-off action of outer shroud 52, the medicament that has adhered to drops because of impact, so the percent recovery improves, does not need to scrape blade.

In addition, the non-tack that rises the interior ring 51 of bucket disk 50 for V-arrangement is handled, after being preferably in hard passivation aluminium and handling, carry out fluorine and infiltrate and handle, even with situation that the gold-plated grade of nickel fluorine eutectoid is compared under, consider from tack, superficial hardness, also be favourable.Particularly, the gold-plated surface of nickel fluorine eutectoid is with in hard passivation aluminium is handled, and carries out fluorine and infiltrates situation about handling and compare, and contact potential difference presents high value, can't medicament be dropped by rise the impact of the on-off action of bucket disk 50 by V-arrangement.

In addition,, the non-tack of coating system also can't guarantee superficial hardness, so preferably do not handle as the non-tack of V-arrangement liter bucket disk 50 because handling.

Also have, the aluminum alloy materials that rises bucket disk 50 as V-arrangement adopts the reason of A5052 material to be: the hardness of the hard passivation aluminium of this material is very carried out fine limit work in the highland.

Rise the occasion of the outer shroud 52 of bucket disk 50 at V-arrangement, also can be after hard passivation aluminium be handled, carry out fluorine and infiltrate processing, if but the contact that harder material impacts each other repeatedly, because both sides produce abrasion, so best V-arrangement rises the outer shroud 52 of bucket disk 50 and adopts after carrying out common passivation aluminium processing, carries out fluorine and infiltrates the mode of handling, thereby make the contact circle of outer shroud 52 can produce abrasion.In addition, because the difference that passivation aluminium is handled, usually, it is different with the color of outer shroud 52 that V-arrangement rises the interior ring 51 of bucket disk 50.But if adopt the A5052 material, then irrelevant with the difference of passivation aluminium processing, form and aspect are silver color series, do not have the not same feeling.Such as, if adopt A6063 material etc., then V-arrangement rises bucket disk 50 and is processed into darker light yellowly, outer shroud 52 is processed into silver color.In order to suppress this aberration, can suppress the not same feeling by making the thickness of film of passivation aluminium of interior ring 51 that V-arrangement rises bucket disk 50 in the scope of 20～30 μ m, still, the difference of form and aspect can easily be confirmed.

Figure 20 rises the figure of the cleaner 53 of bucket disk 50 for the expression V-arrangement.As shown in Figure 19, medicament is assigned to V-arrangement to be risen in the bucket disk 50, V-arrangement rises the position that the S. A. of bucket disk 50 and the packing disk that is arranged at its bottom staggers mutually, after distributing end, move to position on the identical axis at the S. A. that above-mentioned V-arrangement is risen bucket disk 50 and the S. A. of packing disk 54, open the bottom that V-arrangement rises bucket disk 50, the medicament that has distributed is dropped on the packing disk 54.If the reception of medicament finishes, then V-arrangement rises bucket disk 50 and turns back to distribution locations, uses for next preparation.

Here, as shown in Figure 20, by motor 55, V-arrangement rises 56 rotations of bucket pipe, and CR sponge 56a rises the disk 50 that struggles against with V-arrangement and contacts.With this action, by motor 55, by drive transmitting belt 57, skirt shape (skirt) nozzle swing pinion 58,59 rotations of skirt shape (skirt) nozzle, CR sponge 59a partly contacts with the skirt shape that V-arrangement rises the interior ring 51 of bucket disk 50.At this state, make not shown vacuum action, make V-arrangement rise 50 rotations of bucket disk, V-arrangement is risen bucket disk 50 clean.After end, V-arrangement rises bucket disk 56 and turns back to the initial position with skirt shape nozzle 59.

Because as above-mentioned, by after V-arrangement liter bucket disk 50 is carried out the processing of passivation aluminium, it carried out the fluorine infiltration handle, the raising of cleaning property can be not residual more in the past than the medicament of Duoing, thus, can prevent to pollute.

5.V shape rises bucket

As shown in Figure 21, consideration is to following apparatus, carry out the situation that non-tack is handled, in this device, medicament is spread V-arrangement rise in the bucket 60, make surfacing even, open the bottom that V-arrangement is risen bucket 60, medicament is dropped in the branch packaging container 70 of below, by packing hopper 18, medicament in the branch packaging container 70 is dropped in the packing department, and each bag ground is packed it.

In the past, V-arrangement is risen bucket carry out the processing of hard passivation aluminium, still, at the bad also not bad state of the non-tack of medicament, the medicament of micro powder class is attached on the surface.Like this, slightly residue in lip-deep medicament according to handling by the mode of dust collecting fan cleaning, still, obviously, the percent recovery variation of medicament.

So, according to the present invention, after V-arrangement liter bucket 60 is carried out the processing of hard passivation aluminium, it is carried out fluorine infiltrate processing, still, when opening the bottom of V-arrangement liter bucket 60, medicament not exclusively drops, from the teeth outwards, the still slightly residual medicament that has micro powder to be.Yet cleaning property significantly improves, and only by making nozzle approaching, can remove residual slightly medicament.

Even V-arrangement liter bucket 60 is being carried out under the above-mentioned surface-treated situation, the reason that medicament still less drops is: the on-off action that V-arrangement rises bucket 60 moves quietly, when on-off action, does not produce vibration.

So as shown in Figure 21, by support unit 61, by resonant spring parts 62, the supporting V-arrangement rises bucket 60, when on-off action,, provide and knock by screw actuator etc.Thus, slightly be attached to the effect that lip-deep medicament also is subjected to percussion power, can drop 8 one-tenth.That is, such surface treatment improves the non-tack on surface, and by applying vibration, effect increases, and can not improve the non-tack of medicament only by surface treatment.

As making V-arrangement rise the mechanism of bucket 60 vibrations, also can form like this, promptly, rise at V-arrangement on the back plate 64 of header board 63 of bucket 60, form a plurality of grooves 65, the fixed part that is fit to that rises bucket 60 at V-arrangement is installed flexure strip, the projection 66a that is arranged at its leading section is contacted, when V-arrangement rises the switching of bucket 60, when projection 65a crosses groove 65 successively with above-mentioned groove 65, whole V-arrangement rises bucket 60 vibrations, in addition, also can pass through the screw actuator knocking device, knock V-arrangement and rise bucket 60, or, make its vibration by ultrasonic oscillator.At this moment, best, act on long-term effectively in order to make vibration, by leaf spring etc., V-arrangement is risen bucket 60 provides supporting very effective.In addition, also can pass through dust leg 67, the medicament that suction has been adhered to.

Owing to rise in the surface treatment of bucket 60 at V-arrangement, do not require superficial hardness, so even for applying the surface treatment of class, also it doesn't matter, but, can not expect very good effect in the occasion that does not apply vibration.
