The powder anti-locking apparatus 3 of building bridge is to make to importing with the device that does not produce the partial coagulation such as powder bridge formation in the powder material of sleeve pipe 4 interior importings.Specifically, powder is built bridge and is prevented locking apparatus 3, possess to be disposed at and import with in the sleeve pipe 4, in powder material, around a plurality of wire-like members 31 of the S. A. rotary actuation of horizontal direction and be disposed at and import with sleeve pipe 4 outsides, carry out the rotating driving device 32 of the rotary actuation of wire-like members 31.Simultaneously, through importing in the powder material with sleeve pipe 4 interior conveyings, a plurality of wire-like members 31 are rotated driving, to prevent that bridge formation occurs in the powder material waits aggegation.Also have, importing forms along the roughly periphery (with reference to Fig. 2) of the rotary motion trace of wire-like members 31 below the powder conveying space 41 in the sleeve pipe 4.The detailed construction of the anti-locking apparatus 3 of powder bridge formation will be narrated below.
Import with in the sleeve pipe 4, powder build bridge powder conveying space 41 that the wire-like members 31 of anti-locking apparatus 3 rotates more below part, form that top and powder conveying space 41 Even lead to, the importing space 61 of the powder material of the section that is roughly the U font is arranged.In this example, the part (below be designated as jacket casing pipe 62) of delimiting this importing space 61 forms the part of cylinder 6.And, be connected with the end of jacket casing pipe 62 with the delivery pipe 63 of jacket casing pipe 62 Even earthings with powder material.That is to say that in this example, cylinder 6 is by forming the jacket casing pipes 62 that import with the importing space 61 of the below in the powder conveying space 41 of sleeve pipe 4, and with the logical delivery pipe that extends 63 formations of this jacket casing pipe 62 Even.Also have, in this example, form holistic situation as example describes take jacket casing pipe 62 and a part that imports with sleeve pipe 4, still also can replace this this situation, will import with sleeve pipe 4 and jacket casing pipe 62 and form separate member.
Cylinder 6, roughly form generally cylindric, jacket casing pipe 62 its upper openings, it is logical with powder conveying space 41 Even to import space 61.At cylinder 6 interior configuration screw rods 5.Screw rod 5, have screw shaft and be formed at scraper plate on the screw shaft side face, keep suitable gap that the outer circumference end of scraper plate is not contacted with the inner peripheral surface of cylinder 6, under such state, in cylinder 6 (being jacket casing pipe 62 and delivery pipe 63), screw rod 5 is rotated driving.
Specifically, screw rod 5 is made of the 2nd screw rod 54 that is disposed at the 1st screw rod 51 in the jacket casing pipe 62, be connected in delivery pipe 63 interior configurations with the 1st screw rod 51.The 1st screw rod 51 has screw shaft 52, is formed at scraper plate 53, the 2 screw rods 54 on screw shaft 52 side faces, has screw shaft 55 and is formed at scraper plate 56 on screw shaft 55 side faces.
Connect the axial side of jacket casing pipe 62, dispose the end 52a of the screw shaft 52 of the 1st screw rod 51, in the side of jacket casing pipe 62, possess the spiro driving device 57 of this screw shaft of rotary actuation 52 end 52a.Also have, spiro driving device 57 is by CD-ROM drive motor 58 (with reference to Fig. 2), and the rotation amount that the propulsive effort of CD-ROM drive motor 58 is transformed to regulation is consisted of the gear case 59 that the 1st screw rod 51 is rotated driving.
The end of downstream side of the delivery pipe 63 of cylinder 6 forms powder material from the cylinder 6 inner discharge orifice 63a that discharge, and this discharge orifice 63a is logical with sleeve pipe 7 Even with discharge.Also have, discharge possesses the filter unit 71 that is captured in the powder material that dances in the air the inner space with sleeve pipe 7.
Again, each formation section of powder supply device 1 is supported by common substrate 8.
Below, be used as powder build bridge anti-locking apparatus 3 the main portion pie graph Fig. 3 and describe as the build bridge detailed construction of anti-locking apparatus 3 of the powder that Fig. 4 of Fig. 3 A-A line cutaway view possesses powder supply device 1.
As shown in Figure 3 and Figure 4, powder is built bridge and is prevented locking apparatus 3, possess the horizontal direction of being disposed at a plurality of wire-like members 31, support a plurality of wire-like members 31 both ends pair of discs member 33 and with wire-like members 31 equidirectional configurations, simultaneously at the fixing rotating driveshaft 34 of pair of discs member 33.Also have, rotating driveshaft 34, the electrical motor that has with rotating driving device 32 not shown among Fig. 3 and Fig. 4 links, and can be rotated driving.
Wire-like members 31 is in the situation about being driven in rotation in powder material for example, can not support this state under the cantilever status of support, has the wire-like members of tiny section form.Again, preferably form the section form do one's utmost to reduce the face area that contacts with powder material, have that for example circular cross section is then better.In this example, wire-like members 31 adopts has for example 16 linearity members of the circular cross section of the following diameter of 5mm.
Each wire-like members 31 at the periphery of disc element 33 to support the both ends of each wire-like members at the state of 1 first-class arranged spaced of circumference.By supporting both ends at such pair of discs member 33, the support form with wire-like members 31 of smaller circular cross section keeps linearity.Also have pair of discs member 33 and each wire-like members 31 orthogonal configuration that disposes in the horizontal direction.
Rotating driveshaft 34 forms the section rigid body more much bigger than wire-like members 31.Rotating driveshaft 34 the central authorities of disc element 33, be each wire-like members 31 at the center that circumference is arranged, fixedly the pair of discs member 33.
In such powder was built bridge anti-locking apparatus 3, the electrical motor that utilizes rotating driving device 32 was rotated when driving rotating driveshaft 34, drives each wire-like members 31 by pair of discs member 33.Each wire-like members 31 is configured on 1 circumference centered by rotating driveshaft 34, so other whole wire-like members 31 are rotated at the swing-around trajectory of 1 wire-like members 31.
The below describes the relation of screw rod in the powder supply device 1 with such structure 5 with cylinder 6 with the schematic configuration diagram of powder supply device shown in Figure 51.
As shown in Figure 5, cylinder 6 roughly is divided into 2 districts on its throughput direction.Specifically, as 2 districts, be divided into the 1st district S1 that imports powder material and the powder material of carrying from the 1st district S1 is compressed, simultaneously with the 2nd district S2 of powder material to cylinder 6 outer discharges.Also have, the 2nd district roughly also can be described as the district that carries out the conveying of powder material in delivery pipe 63.
The 1st district S1 mainly is made of jacket casing pipe 62 and the 1st screw rod 51, but also can comprise the part of delivery pipe 63 and the 2nd screw rod 54.At the 1st district S1, by hopper 2 and importing sleeve pipe 4, prevented that by the powder bridge formation powder material of the state that locking apparatus 3 stirs is imported in the importing space 61 that is formed between jacket casing pipe 62 and the 1st screw rod 51.Also have, such as Fig. 1 and shown in Figure 5, at the 1st district S1, the angle of scraper plate 53 (angle that direction of principal axis and scraper plate 53 form) is set smallerly, and again, the pitch of teeth also Indeed of scraper plate 53 protects as higher value, can import more equably powder material to 53 of each scraper plates.
The 2nd district S2 mainly is made of delivery pipe 63 and the 2nd screw rod 54.At the 2nd district S2, to compare with the upstream side of throughput direction, the diameter of the delivery pipe 63 in downstream is little, and delivery pipe 63 has the shape that narrows.Therefore, less with the more past downstream of volume in the space of interior all diameter formation of delivery pipe 63 at the 2nd screw rod 54, can compress powder material.Carry out the compression of powder material at the 2nd district S2, can compress like this powder material of 56 of scraper plates, seek to make powder material quantification and the uniformization of conveying.Also have, at the 2nd district S2, the angle initialization of scraper plate 56 must be larger, and set the pitch of teeth of scraper plate 56 smaller.
Simultaneously, will quantitatively carry to discharge orifice 63a at the powder material of delivery pipe 63 interior compressions, and be discharged to from discharge orifice 63a and discharge with in the sleeve pipe 7.
And closely be close to by the discharge orifice 63a that such dispersion member 64 is arranged at delivery pipe 63, can utilize the powder material of 64 pairs of delivery pipe 63 interior conveyings of a plurality of dispersion members to apply resistance.By applying such resistance, can improve the compression to powder material.
Shown in the External view of the 2nd screw rod 54 of Fig. 5 and Fig. 7, arrange on the position that disperses member 64 at the 2nd district S2, on the circumferencial direction hand of rotation of the 2nd screw rod 54 (namely along), form otch 57 at scraper plate 56, prevent from respectively disperseing member 64 and scraper plate 56 mutually to hinder.Such otch 57 preferably forms the size that can avoid disperseing member 64 and scraper plate 56 to be in contact with one another.
And, at the 2nd district S2, also form the scraper plate 58 of the 2nd screw rod 54 in the downstream of the setting position that disperses member 64.Utilize this scraper plate 58, can apply the thrust that makes Qi Qian Jin to utilizing the powder material that disperses member 64 to disperse.
The below is to carrying the action of supplying with powder material to describe in the powder supply device 1 of this example with such formation.
At first, powder material is dropped into hopper 2 when interior, the powder material of input is directed into and imports with in the sleeve pipe 4.Importing with in the powder conveying space 41 of sleeve pipe 4, utilize 32 pairs of a plurality of wire-like members 31 of rotating driving device to be rotated driving, the situation that the partial coagulations such as bridge formation occur in powder material is suppressed.
Specifically, utilize pair of discs member 34 to support a plurality of wire-like members 31 at each both ends in case rotate, all wire-like members 31 is just rotated at a public swing-around trajectory.Again, wire-like members 31 if support its both ends without pair of discs member 34, just can not keep it to support the light-gauge member that has of form (for example linearity form).And wire-like members 31 has the circular cross section little with the face area that contact of powder material around it, and its section form has level and smooth curved surface (being that section is circular), diminishes with the friction force that contacts generation between the powder material.
By consisting of so a plurality of wire-like members 31, even each wire-like members 31 is rotated, the friction force that occurs between the powder material of the interior periphery adjacency of its swing-around trajectory also reduces greatly.Thereby, even a plurality of wire-like members 31 is rotated, also can suppress around it generation of the situation that nearby powder material and wire-like members 31 1 start as far as possible.Therefore can prevent that the rotation of a plurality of wire-like members 31 is on the impact of the powder pressure generation of the powder material around it.Again, such wire-like members 31 also can be described as the member of the impact ground rotation that can not be subjected to powder pressure.
On the other hand, a plurality of wire-like members 31 do to cut off the powder material rotation at swing-around trajectory.Therefore can cut off the aggegations such as bridge formation that produce in the powder material, the generation of inhibition bridge formation etc.
Such effect by means of the anti-locking apparatus 3 of powder bridge formation, as shown in Figure 5, even powder material is in the situation of material horizontal L1 or is in the situation of material horizontal L2 in the hopper 2, also can make the bulk density that imports with the powder material that exists on the following level of the upper end height and position of the swing-around trajectory of sleeve pipe 4 interior a plurality of wire-like members 31 approach the necessarily state of (evenly).
Thereby, can be on one side the stirring of powder material be suppressed on one side the change of the powder pressure of powder material is suppressed, can prevent from simultaneously producing in the powder material powder and build bridge, can improve the quantitative accuracy of the powder material in the 1st district S1 that imports cylinder 6.
At the 1st district S1, at jacket casing pipe 62 interior configuration the 1st screw rods 51, the powder material of importing is drawn towards the space of 53 of the scraper plates of the 1st screw rod 51.The 1st screw rod 51 is rotated driving by spiro driving device 57, and the powder material of introducing 53 of scraper plates utilizes the rotary actuation of the 1st screw rod 51 to be sent to the 2nd district S2 along direction of principal axis.
At the 2nd district S2, the 2nd screw rod 54 is rotated driving with the 1st screw rod 51 by spiro driving device 57.The powder material that the 1st district S1 carries is carried along direction of principal axis by means of the rotary actuation of the 2nd screw rod 54 to 56 movements of scraper plate of the 2nd screw rod 54.At the 2nd district S2, the volume in the space that forms between the interior week of the 2nd screw rod 54 and delivery pipe 63 is set to more past downstream to be reduced, and is simultaneously carrying powder material therefore, and powder material is compressed.And closely be close to by the discharge orifice 63a at delivery pipe 63 a plurality of dispersion members 64 are set, make and disperse member 64 to form resistances, can improve the compression to the powder material of carrying.By like this powder material being compressed, can 56 of scraper plates with impaction state configuration powder material, make the bulk density of powder material keep certain.Particularly, in this example, owing to utilize the anti-locking apparatus 3 of powder bridge formation to seek to make the powder material quantification of the 1st district S1 that imports cylinder 6, can further improve the quantitative accuracy of the bulk density of powder material.
On the other hand, at the 2nd district S2, by means of the 2nd screw rod 54 is rotated driving, while make powder material along the interior revolution of delivery pipe 63 with its conveying.The powder material of carrying like this is in case contact with the member 64 that respectively disperses that is fixed in delivery pipe 63, just by means of powder material with respect to the relatively rotating of dispersion member 64, apply shearing force by 64 pairs of powder materials that compressed of dispersion member.Utilize this shearing force effectively to disperse the powder material that compressed, make the powder material under the state of compressing form homodisperse state.
The powder material of disperse state provides the thrust of Qian Jin by being arranged at the scraper plate 58 that disperses member 64 downstreams.By means of this, the powder material of homogeneously dispersed state is from discharge orifice 63a to discharging with discharging with quantitative and uniform state in the sleeve pipe 7.
If adopt the powder supply device 1 of this example, then be formed on and import with in the sleeve pipe 4, a plurality of wire-like members 31 of rotating in powder material form the have light section member of (for example circular cross section), and whole wire-like members 31 structures of rotating at a public swing-around trajectory.Therefore, even a plurality of wire-like members 31 is rotated, the friction force that produces between the interior periphery of this swing-around trajectory and adjacent powder material also greatly reduces.Thereby, even a plurality of wire-like members 31 are rotated, the powder material that also can do one's utmost to suppress around it nearby makes it mobile with wire-like members 31, can prevent because the rotation of a plurality of wire-like members 31 and powder pressure of the powder material around it is exerted an influence.On the other hand, a plurality of wire-like members 31 are rotated at swing-around trajectory cutting powder material.Therefore can suppress to occur in the powder material situation of the aggegations such as bridge formation.Thereby, can be on one side the stirring of powder material be suppressed on one side the change of the powder pressure of powder material is suppressed, can prevent that simultaneously the powder that produces in the powder material from building bridge, can improve the quantitative accuracy of the interior powder material of the 1st district S1 that imports cylinder 6.
Again, at the 2nd district S2, more reduce in the more past downstream of volume that is set as the space that forms between the interior week of the 2nd screw rod 54 and delivery pipe 63, can be simultaneously powder material to be compressed carrying powder material therefore.And by near the discharge orifice 63a of delivery pipe 63, a plurality of dispersion members 64 being set, can utilizing and disperse the powder material of 64 pairs of conveyings of member to apply resistance, strengthen the compression to powder material.By like this powder material being compressed, can at 56 state configuration powder materials to compress of scraper plate, at the 2nd district S2 the bulk density of powder material be kept necessarily.
At the 2nd district S2 of cylinder 6, a plurality of dispersion members 64 that are fixed in highlightedly delivery pipe 63 from the inside face of delivery pipe 63 to the inner space are set again.Therefore utilize the rotary actuation of the 2nd screw rod 54 to disperse member 64 to relatively rotate along the powder material that the interior revolution of delivery pipe 63 is carried with respect to each on one side on one side.Thereby, contact with disperseing member by making the closely powder material that compressed at the 2nd district S2, can utilize to relatively rotate the dispersion effect that increases powder material.
Also by the downstream at the setting position that disperses member 64 scraper plate 58 is set, to utilizing the powder material that disperses under the state that member 64 disperseed, can applies Qian Jin De Tui Jin power, from discharge orifice 63a it is discharged quantitatively.
Thereby, in powder supply device 1, can improve quantitative accuracy and the homogeneity of carrying the powder material of supplying with.
In the superincumbent explanation, wire-like members 31 is illustrated as an example of situation with circular cross section example, but so long as can reduce and powder material on every side between the section form of friction get final product, form curved surface with the part of the outer circumferential side of swing-around trajectory and interior all side contacts and get final product.Also have, from so that the face area that contact with powder material is reduced to minimal consideration, wire-like members 31 formation circular cross sections are desirable.
The situation of the above take the support form of the wire-like members 31 between the pair of discs member 34 as linearity is illustrated as example, but supports that form also can be the mixed style of curve-like or straight line and curve.But, from the consideration of the face area that reduces to contact with powder material, support that form is that linearity is desirable.
Simultaneously, wire-like members 31 also can adopt the member of wire-like or piano wire etc., is utilizing pair of discs member 34 to give the member of being supported under the state of tension force.
Again, the characteristic of velocity of rotation and powder material is preferably considered in the setting of the number of wire-like members 31, is set as to make the powder material can be with certain delivery speed by between the adjacent wire-like members 31.
Powder material for example adopts easily because friction occurs in the situation of raw material of static, uses the powder of this example anti-locking apparatus 3 of building bridge can reduce friction between powder material and the wire-like members 31, suppresses the generation of static, suppresses the formation of bridge formation etc.
Also have, the above is configured in the situation of the direction (being horizontal direction) of throughput direction (the being above-below direction) orthogonal of powder material take each wire-like members 31 and is illustrated as example, but as long as the direction of intersecting at the throughput direction with powder material disposes wire-like members.
Simultaneously, support that the disc element 34 of a plurality of wire-like members 31 can not be discoid also, also can adopt the tabular component of other shapes such as polygon.
As powder build bridge the hopper 2 that consists of beyond the anti-locking apparatus 3, import with sleeve pipe 4, tins 6 the 1st district S1 etc. and can adopt form beyond the above-mentioned formation.
Can adopt the determinator that makes powder supply device 1 possess the weight of the powder material in the determinator, can measure the weight minimizing of the powder material in the device of carrying powder material and causing to outer discharge of device, to the reduction of weight quantitative powder supply device in addition.
The above is illustrated as example take build bridge situation that anti-locking apparatus 3 is used in powder supply device 1 of powder, but so long as have the device in the powder conveying path that requirement quantitatively carries, just can use powder of the present invention to build bridge and prevent locking apparatus.
