Description
Technical field
The present invention relates between device for conveying and switching corresponding to the powder and granular material between the downstream air carrying path of the upstream side air carrying path of the dual system of two kinds of powder and granular materials and triangular web.
Background technology
In the past, pulverize waste material resins such as the sprue follow forming synthetic resin to produce, cross gate by comminutor, mixed this comminution of material and original (virgin) material, utilized this composite material section various synthetic resin articles that are shaped.
Thus, can keep quality to a certain degree, and by utilizing the waste material resin to come cost-cutting again.
Perhaps, also can mix multiple material, to this composite materials of supply such as ester moulding machines.
But, when mixing not same material as described above, in order to keep molded item quality, need be with the broken material of cooperation ratio mixed powder and the firsthand data of regulation.In addition, even when mixing multiple material, also need to be mixed into the cooperation ratio of regulation.Therefore, in the following way, promptly, from stockpiling comminution of material and firsthand data respectively, perhaps the powder and granular material of two kinds of powder and granular materials stockpiles groove (blowing engine: the drip catcher blower) is carried comminution of material and firsthand data or two kinds of powder and granular materials by attracting air, and mixes with the cooperation ratio of regulation to being connected suction pump via the air carrying path.
In such mode, use the device for conveying and switching of following powder and granular material, its from stockpiled respectively that two powder and granular materials of same material not stockpile the upstream side air carrying path of the dual system that groove begins and as the downstream air carrying path of carrying the destination between.
For example, motion has between corresponding to the shifter between the air carrying path of the triangular web in the air carrying path of the dual system of two kinds of powder and granular materials and its downstream in following patent documentation 1.
This shifter roughly possesses: two barrel (upstream side breeches pipe) of upstream side are connected with the air carrying path of above-mentioned dual system respectively; Glide base (lower case: 1ower case), offer two peristomes that are communicated with these two barrel respectively, and two peristomes are approaching mutually; Tabular transfer valve slides in this glide base; Base seat lid (upper case: upper case), connect the downstream be arranged on this transfer valve, offer the downstream peristome that is communicated with the air carrying path of the triangular web in above-mentioned downstream.
Based on Figure 25 above-mentioned shifter in the past is described roughly.In addition, the example of use cylinder as the driver element of transfer valve is described.
In Figure 25, above-mentioned shifter 100 roughly is shown, the transfer valve 120 that illustrates glide base 110, in this glide base 110, slides, make the cylinder 130 of an example of the driver element of its slip as this transfer valve 120 of Sliding Control.
On above-mentioned glide base 110, along the direction of slip of transfer valve 120, offer two peristomes 111,112, and two peristomes 111,112 are approaching mutually.Each of these peristomes 111,112 and the piping shape kissing of air carrying path are combined in the circle of overlooking under the observation, in addition, consider respectively the thickness that connects the pipe arrangement (above-mentioned two barrel) on the upstream side that is arranged on these peristomes 111,112 etc., separate certain interval and offer these peristomes 111,112.
Above-mentioned transfer valve 120 forms tabular, has two occlusive parts 121,122 of cylinder side of laying respectively at (rear side) and front side and is opened in through-hole part 123 between these occlusive parts 121,122 along direction of slip.For the powder and granular material of carrying air to carry glibly, this through-hole part 123 be with above-mentioned peristome 111,112 roughly unidimensional with shape in the circle of overlooking under the observation.
Above-mentioned cylinder 130 possesses usually: piston 131 is arranged in the cylinder housing; Piston rod 132 is connected from cylinder housing flexible with this piston 131; Inrush of air flows out pipeline 134,135, is located at respectively on the end, direction of slip front and back of cylinder housing, is used to pass air into outflow.
Above-mentioned piston rod 132 and transfer valve 120 link together by connecting portions such as tie bolt 133.
In the shifter 100 of said structure, certain occlusive part 121,122 by transfer valve 120 stop up glide bases 110 peristome 111,112 one of them the time, for example, shown in Figure 25 (a), when the occlusive part 122 of the front side that passes through transfer valve 120 stops up the peristome 112 of front sides, through-hole part 123 is overlooked to observe and is overlapped with the peristome 111 of rear side, and thus, the air carrying path that is communicated with the upstream side that is provided with this peristome 111 is communicated with the air carrying path in downstream.
Shifter 100 according to such formation, for the powder and granular material of carrying by the attraction air, by the transfer valve 120 that slides at orthogonal directions roughly, powder and granular material is snapped between the face (upper surface of sliding tray) of sliding support transfer valve 120 of the face (back side) of glide base 110 1 sides of transfer valve 120 and glide base 110, therefore, can reduce because of snapping in the spillage of the conveying escape of air that powder and granular material causes.
Patent documentation 1: TOHKEMY 2007-320686 communique.
But, in above-mentioned patent documentation 1, in the shifter 100 of motion, may produce following such problem.
Shown in Figure 25 (a), under with the situation of cylinder 130 as the driver element of transfer valve, when the piston rod 132 that is in the shortening state is stretched out, flow out the rear side space importing pressurized air of the piston 131 of pipeline 134 in cylinder housing from the inrush of air of rear end side.Thus, utilize pressurized air piston 131 forwards to move, piston rod 132 stretches out, and transfer valve 120 forwards slides and moves.At this moment, shown in Figure 25 (b), in cylinder housing, import pressurized air, and in the front face side of piston 131, the air that exists in the side space follows the mobile of piston 131 to be compressed in front to the rear side space of piston 131.The cutoff port that is provided with on the inrush of air outflow pipeline 135 of the front that is connected in cylinder housing etc. is adjusted at the discharge of compressed air in this front face side space, gently flows out compressed air in this front face side space.In addition, piston 131 forwards moves when being subjected to the resistance that compressed air produced in this front face side space.
Follow piston 131 forwards to move as described above, transfer valve 120 forwards moves.In this moves, shown in Figure 25 (c), between rearward end upstream side edge of opening (paper in the birds-eye view is by the lining direction) 123a of the through-hole part 123 of leading section downstream edge of opening (the outer direction of the paper in the birds-eye view) 111a of the rear side peristome 111 of glide base 110 and transfer valve 120, might snap in powder and granular material p.In diagram, omitted the following state that snaps in, but it is opposite, promptly, shown in Figure 25 (d), stretching out to greatest extent from piston rod 132, the state that transfer valve 120 the is positioned at front side piston rod 132 that begins to withdraw, transfer valve 120 rearward slides when mobile, might snap in powder and granular material p between rearward end downstream edge of opening (the outer direction of the paper in the birds-eye view) 112a of the front side peristome 112 of leading section upstream side edge of opening (paper in the birds-eye view is by the lining direction) 123b of this through-hole part 123 and glide base 110.
If snap in powder and granular material p on above-mentioned position, then transfer valve 120 stops to slide and moves, because this powder and granular material p, the rear side occlusive part 121 that rear side peristome 111 is not switched valve 120 stops up fully, and formation gap sp1.
If form such gap sp1, then leak the attraction air that is used for the air conveying, on the side that should carry, promptly from the rear side peristome 111 that snaps in powder and granular material p, in the side opening portion 112, the flow that is used for the attraction air of air conveying reduces forwardly.As a result, can not be glibly downstream side carry powder and granular material p, powder and granular material might stop up the air carrying path.In addition, on the contrary, that is, between the rearward end downstream edge of opening 112a of the front side peristome 112 of the leading section upstream side edge of opening 123b of through-hole part 123 and glide base 110, snap under the situation of powder and granular material, also be formed with gap sp1 same as described above.
In addition, as the other problems point, as originally in the past shown in the example, with cylinder during as the driver element of transfer valve, owing to snap in powder and granular material p as described above, transfer valve 120 stops to slide under the mobile state, and the pistons 131 in the cylinder 130 also stop to move.At this moment, because from outflow air such as above-mentioned cutoff ports, so the front face side space of piston 131 becomes approximate atmospheric environment.Under such state, drop, cut off or rupture at the powder spare material p that snaps in above-mentioned position, when the state of snapping in is disengaged, even in piston 131 stops, also import pressurized air to its rear side space, in addition, because the front face side space becomes the environment approximate with barometric pressure as described above, so do not produce the enough resistances that produce because of pressurized air as described above, thereby piston 131 forwards moves on the front inner wall that might collide cylinder housing (omit explanation but identical when opposition side moves) at a high speed.
For the high-speed mobile of such piston 131, under the bigger situation of residue stroke amount (amount of movement) st1 (with reference to Figure 25 (c), (d)) of front end from the stop position of piston 131 to cylinder housing or rear end, the air that exists in the front face side space of piston 131 or the rear side space is compressed because of the mobile of piston 131, generation is from the resistance of this compressed air, and therefore the high-speed mobile of piston 131 is as described above slowed down.
Therefore, in order to prevent the high-speed mobile of piston 131, consider to form significantly the space between front side peristome 112 and the rear side peristome 111, and utilize the big cylinder of stroke amount, increase because of snap in that powder and granular material produces from the stop position of piston 131 to the front end of cylinder housing or the residue stroke amount of rear end.But, if become such structure, then device maximizes, and snapping under the situation of powder and granular material, the peristome of the side that should carry is overlooked observation and is not overlapped with the through-hole part of transfer valve, perhaps diminish, carry thereby might carry out air glibly to overlook observation coincidence area.Therefore, need moderately near offering front side peristome 112 and rear side peristome 111.
On the other hand, smaller below the normally about 5mm of the size of the powder and granular material that snaps in (powder diameter), thus the above-mentioned residue stroke amount st1 that is in the state that snaps in powder and granular material and stop to diminish.As a result, in the front face side space or rear side space of as described above piston 131, pressurized air does not produce enough resistances, piston 131 at a high speed forwards or the rear move, might collide on the front end or rear end inwall of cylinder housing.
The impact load that produces when above-mentioned collision acts on the piston rod 132 of cylinder 130 and the transfer valve 120 bonded assembly connecting portions 133 mainly as compression, tensile load, but as described above, snap in then piston 131 high-speed mobile of state if remove, therefore the permissible stress that might this impact load surpasses connecting portion 133 is because this impact load makes connecting portion 133 fractures.
Perhaps, if repeatedly as described above snap in powder and granular material and releasing snaps in powder and granular material, repeatedly impact load of effect then might cause the fatigue damage of this connecting portion 133 on connecting portion 133.

In addition, shown in Fig. 4 (c), (d), shorten at piston rod 43, transfer valve 20 is positioned under the state of rear position, the through-hole part 22 of transfer valve 20 overlaps with the rear side peristome 14 of glide base 10, through-hole part 22 is communicated with rear side peristome 14, and the front side occlusive part 23 of transfer valve 20 stops up the front side peristome 13 of glide base 10.
As mentioned above, under the state that does not snap in powder and granular material, since the through-hole part 22 of transfer valve 20 with become the identical circular under overlooking of approximate diameter as described above respectively with each upstream side peristome 13,14 of these through-hole part 22 bonded assemblys, become the state of coincidence fully so overlook.In addition, become following state, that is,, stop up the front side peristome 13 and the rear side peristome 14 of glide base 10 respectively fully by the front side occlusive part 23 and the rear side occlusive part 24 of transfer valve 20.
In addition, under this state, also same as described above at above-mentioned each notch 15,16 that each of the front side peristome 13 of glide base 10 and rear side peristome 14 forms near side end, become the state that the front side occlusive part 23 that is switched valve 20 and rear side occlusive part 24 stop up.
On the other hand, stretch out at piston rod 43, transfer valve 20 forwards slides when mobile the position, shown in Fig. 6 (a) and (b), at the rearward end upstream side edge of opening 22b of the through-hole part 22 of transfer valve 20 be located between the rear side notch 16 on the leading section of rear side peristome 14 of glide base 10 and snap under the situation of powder and granular material p, above-mentioned through-hole part 22 not exclusively overlaps under overlooking with front side peristome 13, side is because above-mentioned snapping in forms gap sp2 in the wings.
In addition, on the contrary, promptly, shorten at piston rod 43, transfer valve 20 rearward slides also identical when mobile in the position, shown in Fig. 6 (c), (d), at the leading section upstream side edge of opening 22a of the through-hole part 22 of transfer valve 20 be located between the front side notch 15 on the rearward end of front side peristome 13 of glide base 10 and snap under the situation of powder and granular material p, above-mentioned through-hole part 22 and rear side peristome 14 not exclusively overlap overlooking down, side is because above-mentioned snapping in forms gap sp2 forwardly.
Even under the situation that snaps in powder and granular material p as described above, device for conveying and switching 1 according to the powder and granular material of present embodiment, because as described above each upstream side peristome 13,14 near side end on form notch 15,16 respectively, so the powder and granular material p that snaps in is directed to these notchs 15,16, snap in notch 15,16, therefore, can make gap sp2 less than the shifter that illustrates in the above-mentioned example in the past.Therefore, can reduce from what the upstream side peristome 13,14 of the side that snapped in powder and granular material p leaked and be used for the attraction leakage of air amount that air is carried.
Especially, in the present embodiment, because forming, overlooks down above-mentioned each notch 15,16, its radius of curvature is less than the little circular shape of the radius of each upstream side peristome 13,14, so at slip transfer valve 20, the direction of slip terminal part of through-hole part 22 was overlooked the coincidence area that is coinciding down with the notch 16 that is located on the rear side peristome 14 when side opening portion 13 slips forwards of the through-hole part 22 of transfer valve 20 were mobile, became less than for example only being circular peristome.Therefore, can reduce the rate that snaps in of powder and granular material p effectively.
In addition, the radius of curvature of notch 15,16 is at more than 2 times of powder diameter of powder and granular material p, and below 2/3 of radius at upstream side peristome 13,14, therefore can more effectively reduce the rate of snapping in, even and under the situation that snaps in powder and granular material p, also can reduce the leakage of air amount in the peristome that snaps in side.
Further, as mentioned above, owing to make each notch 15,16 become little circular-arc under overlooking respectively, so when on position as described above, having snapped in powder and granular material, on the direction that the through-hole part 22 of transfer valve 20 slides, become easily along this roundlet arc to each notch 15,16 these powder and granular material of guiding.That is, do not make transfer valve 20 stop to move midway at the powder and granular material that snaps in of each notch 15,16, be easy to along this roundlet arc with this plastochondria material guide to each notch 15,16 near side end.
And, in the present embodiment, each notch the 15, the 16th only forms the structure of recess in transfer valve 20 sides, form stage portion 15a, 16a as mentioned above, therefore compare with the situation that on the whole thickness direction of glide base, forms notch, can improve rigidity and air-tightness between the upstream side peristome 13,14.
In addition, on the position of the upstream side of separately upstream side peristome 13,14, be formed with stage portion 15a, 16a and do not form notch, therefore, owing to exist this position to be difficult to snap in the powder and granular material of carrying to each upstream side peristome 13,14 air, thereby can more effectively reduce the rate that snaps in of powder and granular material.
Further, in the present embodiment, the step upper surface of above-mentioned stage portion 15a, 16a becomes respectively side (below) bevelled dip plane upstream, therefore can reduce adhering to, piling up of powder body etc.In addition, can not become such dip plane, and become horizontal surface.
In addition, as mentioned above, if the maximum width of each notch 15,16 of little circular shape becomes about 1/2～2 times of powder diameter of powder and granular material, then under the situation of the powder and granular material p that snaps in the air conveying, snapped in powder and granular material p to overlook down the mode that is contained in these notchs 15,16, the upstream side peristome that snaps in side becomes the state that the occlusive part 23,24 that is switched valve 20 roughly stops up, and therefore can more effectively reduce the leakage of air amount in the peristome that snaps in side.
Especially, in the present embodiment, owing to become the maximum width that the average powder diameter of the powder and granular material of carrying with air matches, so under the situation that snaps in powder and granular material p, snap in powder and granular material p to overlook down the mode that is contained in fully in the notch 15,16, therefore can more effectively reduce the leakage of air amount in the peristome that snaps in side.
The action of the cylinder 40 when then, illustrating that based on Fig. 5 and Fig. 7 transfer valve 20 carries out change action.
Shown in Fig. 5 (a), when elongation was in the piston rod 43 of shortening state, the rear side space of flowing out the piston 42 of pipeline 45 in cylinder housing 41 from the rear end side inrush of air imported pressurized air.Thus, piston 42 forwards moves because of pressurized air, and piston rod 43 slowly extends.
At this moment, shown in Fig. 5 (b), in cylinder housing 41, importing to piston 42 rear side spaces has pressurized air, and in the front face side of piston 42, the air that exists in the side space follows the mobile of piston 42 to be compressed in front.Flowing out cutoff port on the pipeline 44 etc. at this compressed air in front face side space by the front inrush of air that is located at cylinder housing 41 adjusts discharge and slowly flows out.In addition, it is forwards mobile that piston 42 bears the resistance that compressed air produced in this front face side space.
By piston 42 is forwards mobile as described above, shown in Fig. 5 (c), piston rod 43 extends to greatest extent, and transfer valve 20 is positioned at anterior position.
In addition, omit detailed explanation, but opposite, that is, when piston 42 was rearward mobile, the front face side space of flowing out the piston 42 of pipeline 44 in cylinder housing 41 from the front inrush of air imports pressurized air, and was same as described above, and piston 42 is rearward moved.
On the other hand, forwards slide when mobile the position at piston rod 43 elongation, transfer valve 20, shown in Fig. 7 (a) and (b), at the rearward end upstream side edge of opening 22b (with reference to Fig. 6 (b)) of the through-hole part 22 of transfer valve 20 be located between the rear side notch 16 on the leading section of rear side peristome 14 of glide base 10 and snap under the situation of powder and granular material p, shown in Fig. 7 (c), the piston 42 in the cylinder housing 41 stops to move.
If piston 42 stops like this, then owing to, be similar to atmospheric environment so the front face side space of piston 42 becomes from being located at the outflow air such as cutoff port on the above-mentioned front inrush of air outflow pipeline 44.
Under above-mentioned state, if snapping in the powder and granular material p of above-mentioned position drops, cut off or rupture and removed the state that snaps in powder and granular material p, even then in piston 42 stopped processes, also flow out pipeline 45 and import pressurized air to its rear side space from the rear end side inrush of air, in addition, in front in the side space, owing to become as described above and be similar to atmospheric environment, so pressurized air does not produce enough resistances as described above, piston 42 forwards moves at a high speed, the front inner wall of collision cylinder housing 41 and stop (Fig. 7 (d)).
In addition, omit detailed explanation, but opposite, promptly also identical when piston 42 is rearward mobile, piston 42 rearward moves at a high speed, the rear end inwall of collision cylinder housing 41 and stopping.
As mentioned above, if the front inner wall of piston 42 high-speed mobile collision cylinder housing 41, then as the above-mentioned explanation of example in the past, impact load acts on the tie bolt 25, according to present embodiment, owing to form notch 15,16, the powder and granular material p that snaps in is directed to notch 15,16, compare with above-mentioned shifter in the past, the position that snaps in powder and granular material p moves to the direction of slip end side of transfer valve 20.Thus, even the powder and granular material p that snaps in drops, cut off or rupture and remove under the situation that snaps in powder and granular material p, also can make from because of the stop position that snaps in the piston 42 that powder and granular material p stopped to the residue stroke amount st2 (with reference to Fig. 7 (c), (d)) of the piston 42 of the front end of cylinder housing 41 or rear end inwall less than above-mentioned example in the past.
Therefore, piston 42 moves aforesaid residue stroke amount st2, thereby can reduce the impact load that acts on the tie bolt 25 that piston rod 43 is connected with transfer valve 20 that inwall produced of collision cylinder housing 41.Therefore, the fracture or the fatigue damage of connecting portion can be reduced effectively, thereby the durability of device can be improved.

In addition, the device for conveying and switching 1A of the powder and granular material of the present embodiment also device for conveying and switching 1 with the powder and granular material of above-mentioned first embodiment is identical, can be applied to the delivery system based on the powder and granular material of Fig. 8 explanation.
In the device for conveying and switching 1A of the powder and granular material of present embodiment, on glide base 10C, not establish notch, and on transfer valve 20A, establish notch, this point is the main point different with above-mentioned first embodiment.
Promptly, shown in Figure 12 (a) and (b), transfer valve 20A forms the notch 28,29 (front side notch 28 and rear gal notch 29) that extends to outside (the place ahead and rear) on the both ends of the direction of slip of the through-hole part of offering along the substantial middle portion in tabular valve body 21A 22.
Each notch 15,16 of the little circular shape that above-mentioned each notch 28,29 and above-mentioned first embodiment are illustrated is identical, overlooks (looking up) and is little circular shape, and its radius of curvature is less than the radius of the through-hole part 22 of circular.
The powder diameter of the powder and granular material that the above-mentioned radius of curvature of these notchs 28,29 can be carried corresponding to air or the diameter of through-hole part 22 are suitably set, but it is identical with above-mentioned first embodiment in the present embodiment, at more than 2 times of powder diameter of powder and granular material, and in below 2/3 of radius of through-hole part 22.
In the present embodiment, when the average powder diameter of powder and granular material p (with reference to Figure 13) was 3mm, the diameter of through-hole part 22 was 42mm, and the radius of curvature of each notch 28,29 is respectively 12.5mm, but is not limited thereto, can be in above-mentioned scope.
In addition, the maximum width of each notch 28,29 of above-mentioned little circular shape, promptly, the powder diameter of the powder and granular material that can carry corresponding to air to the width of the direction of slip outermost method, edge of each notch 28,29 from the edge, both ends of through-hole part 22 etc. is suitably set, but identical with above-mentioned first embodiment, preferably become about 1/4～5 times of powder diameter of powder and granular material.More preferably make above-mentioned maximum width become about 1/2～2 times of powder diameter of powder and granular material.In the present embodiment, as mentioned above, when the average powder diameter of powder and granular material p was 3mm, the above-mentioned maximum width of above-mentioned each notch 28,29 was 3mm.
Through-hole part 22 and each notch 28,29 each center of circle are located along the same line along direction of slip, and notch 28,29 each center of circle lay respectively at the foreign side that compares with the center of circle of through-hole part 22.
In addition, in the present embodiment, notch 28,29 is not formed on the whole thickness direction of tabular valve body 21A of transfer valve 20A, only cuts the upstream side of this tabular valve body 21A, only forms recess in glide base 10C side.By like this notch 28,29 being formed the recess structure, on its downstream side part, form stage portion 28a, 29a.
That is, can not see two notchs 28,29 from the upper surface side of transfer valve 20A, and through-hole part 22 that only can the visuognosis circular.
Further, the step surface of above-mentioned stage portion 28a, 29a is respectively side (top) bevelled dip plane downstream.
In addition, shown in Figure 12 (c), (d), above-mentioned glide base 10C removes and do not form beyond the notch, and is identical with the glide base structure of above-mentioned first embodiment.
Then, the change action of the transfer valve 20A among the device for conveying and switching 1A of powder and granular material of said structure is described based on Figure 13 and Figure 14, and the action of the cylinder 40 of this transfer valve 20A when carrying out change action.
Figure 13 (a)～(d) is used for illustrating the instruction diagram that snaps in the state of powder and granular material at same device for conveying and switching, (a) be approximate vertical view, (b) be the summary longitudinal section of (a), (c) be approximate vertical view, (d) be the summary longitudinal section of (c), Figure 14 (a)～(d) is the approximate vertical view that schematically is illustrated in the action of the cylinder under the state that snaps in powder and granular material in the same device for conveying and switching.
In addition, when regular event, the transfer valve 20A that does not promptly snap in the state of powder and granular material carries out change action, and the action of the cylinder 40 of this transfer valve 20A when carrying out change action is identical with above-mentioned first embodiment, therefore omits explanation.
The change action of transfer valve 20A at first, is described based on Figure 13.
Shown in Figure 13 (a) and (b), forwards slide when mobile the position at piston rod 43 elongation, transfer valve 20A, between the leading section downstream edge of opening 14a of the rear side peristome 14 of rear side notch 29 that the rearward end upstream side incision of the through-hole part 22 of transfer valve 20A forms and glide base 10C, snap under the situation of powder and granular material p, above-mentioned through-hole part 22 and front side peristome 13 are overlooked coincidence fully under the observation, side in the wings, because the above-mentioned powder and granular material p that snaps in like that forms gap sp3.
In addition, on the contrary, promptly, shorten at piston rod 43, transfer valve 20A rearward slides also identical when mobile in the position, shown in Figure 13 (c), (d), between the rearward end downstream edge of opening 13a of the front side peristome 13 of front side notch 28 that the leading section upstream side incision of the through-hole part 22 of transfer valve 20A forms and glide base 10C, snap under the situation of powder and granular material p, above-mentioned through-hole part 22 and rear side peristome 14 are overlooked down not exclusively coincidence, side forwardly, because the above-mentioned powder and granular material p that snaps in like that forms gap sp3.
Even under the above-mentioned situation that snaps in powder and granular material p like that, device for conveying and switching 1A according to the powder and granular material of present embodiment, owing on the direction of slip both ends of the through-hole part 22 of transfer valve 20A, form notch 28,29 respectively as mentioned above, so the powder and granular material p that snaps in is directed to these notchs 28,29, snap in notch 28,29, therefore can make gap sp3 less than the illustrated shifter of above-mentioned example in the past.Therefore, can reduce from what the upstream side peristome 13,14 of the side that snaps in powder and granular material p leaked and be used for the attraction leakage of air amount that air is carried.
Especially, in the present embodiment, because above-mentioned each notch 28,29 forms and overlooks, its radius of curvature is less than the little circular shape of the radius of through-hole part 22, so slide at transfer valve 20A, the through-hole part 22 of transfer valve 20A forwards side opening portion 13 slides when mobile, is located at the rear side notch 29 of direction of slip terminal part (rearward end) of through-hole part 22 and the leading section of rear side peristome 14 and overlooks the coincidence area that coincides under the sight, becomes less than for example only being circular through-hole part.Therefore, can reduce the rate that snaps in of powder and granular material p effectively.
In addition, the radius of curvature of notch 28,29 is at more than 2 times of powder diameter of powder and granular material p, and below 2/3 of radius at through-hole part 22, therefore can more effectively reduce the rate of snapping in, even and under snapping in powder and granular material p situation, also can reduce leakage of air amount in the peristome that snaps in side.
Further, as mentioned above, each notch 28,29 is respectively the little circular shape under overlooking, when therefore on position as described above, snapping in powder and granular material, on the reversing sense that the through-hole part 22 of transfer valve 20A slides, be easy to along this roundlet arc to each notch 28,29 these powder and granular material of guiding.That is, each notch 28,29 snap in powder and granular material midway, transfer valve 20A does not stop to move, and along this roundlet arc this powder and granular material is guided to the direction of slip most external of each notch 28,29 easily.
In addition, in the present embodiment, each notch 28,29 constitute only at glide base 10C side formation recess, form stage portion 28a as described above, 29a, therefore as described above at the edge of opening and the upstream side peristome 13 of the direction of slip end side of the through-hole part 22 of transfer valve 20A, 14 near there being the powder and granular material of air in carrying between the side end edge of opening, when snapping in powder and granular material as described above, cut off this powder and granular material stream and snap in powder and granular material, and by above-mentioned stage portion 28a, 29a more effectively cuts off powder and granular material stream and reduces the attraction leakage of air.
Further, in the present embodiment, the step surface of above-mentioned stage portion 28a, 29a is difference side (top) bevelled dip plane downstream, therefore can reduce the influence to the powder and granular material that normally carries out the air conveying.

In addition, during regular event, promptly do not snap in the change action of the transfer valve 20A in the state of powder and granular material, and the action of the cylinder 40 of this transfer valve 20A when carrying out change action is identical with above-mentioned first embodiment, therefore omits explanation.
The change action of transfer valve 20A at first, is described based on Figure 17.
Shown in Figure 17 (a) and (b), forwards slide when mobile the position at piston rod 43 elongation, transfer valve 20A, snap under the situation of powder and granular material p at rear side notch 29 that the rearward end upstream side incision of the through-hole part 22 of transfer valve 20A forms with between the rear side notch 16 that the leading section downstream incision of the rear side peristome 14 of glide base 10 forms, above-mentioned through-hole part 22 not exclusively overlaps under overlooking with front side peristome 13, side in the wings, owing to snap in above-mentioned powder and granular material p, form gap sp4.
In addition, on the contrary, promptly, shorten at piston rod 43, transfer valve 20A rearward slides also identical when mobile in the position, shown in Figure 17 (c), (d), between the front side notch 15 that forms at front side notch 28 that the leading section upstream side incision of the through-hole part 22 of transfer valve 20A forms with in the rearward end downstream of the front side peristome 13 of glide base 10, snapped in powder and granular material p, this moment, above-mentioned through-hole part 22 not exclusively overlapped under overlooking with rear side peristome 14, side forwardly, owing to snap in this powder and granular material p, form gap sp4.
Even under the above-mentioned situation that snaps in powder and granular material p like that, device for conveying and switching 1B according to the powder and granular material of present embodiment, on the direction of slip both ends of the through-hole part 22 of transfer valve 20A, form notch 28,29 respectively as mentioned above, and the upstream side peristome 13,14 of glide base 10 separately near side end on form notch 15,16, therefore the powder and granular material p that snaps in is directed snapping in notch 15,16,28,29 to these notchs 15,16,28,29.That is, shown in Figure 17 (a) and (b), be directed between the rear side notch 16 of rear side peristome 14 of the rear side notch 29 of through-hole part 22 of transfer valve 20A and glide base 10, and snap between these.Perhaps, shown in Figure 17 (c), (d), be directed between the front side notch 15 of front side peristome 13 of the front side notch 28 of through-hole part 22 of transfer valve 20A and glide base 10, and snap between these.
Therefore, can make because of snapping in gap sp4 that powder and granular material p forms much smaller than the illustrated shifter of above-mentioned example in the past, and can be less than above-mentioned first embodiment and second embodiment.Therefore can reduce the attraction leakage of air amount that is used for the air conveying of leaking from the upstream side peristome 13,14 that snaps in powder and granular material p one side.
Especially, in the present embodiment, above-mentioned each notch 15,16,28,29 form its radius of curvature respectively less than through-hole part 22 and each upstream side peristome 13 under overlooking, the little circular shape of 14 radius, therefore slide at transfer valve 20A, when side opening portion 13 slips forwards of the through-hole part 22 of transfer valve 20A are mobile, the front side notch 16 that is located at the rear side notch 29 on the direction of slip terminal part (rearward end) of through-hole part 22 and is located on the leading section of rear side peristome 14 is overlooked the coincidence area that is coinciding down, less than for example only becoming circular through-hole part and/or upstream side peristome.Therefore, can reduce the rate that snaps in of powder and granular material p effectively.
In addition, the radius of curvature of notch 15,16,28,29 is at more than 2 times of powder diameter of powder and granular material p, and below 2/3 of radius at through-hole part 22, therefore can more effectively reduce the rate of snapping in, even and under the situation that snaps in powder and granular material p, also can reduce the leakage of air amount in the peristome that snaps in side.
Further, as mentioned above, each notch 15,16,28,29 becomes the little circular shape under overlooking respectively, when in aforesaid position, snapping in powder and granular material, direction along the through-hole part 22 of transfer valve 20A slides is easy to along these roundlet arcs to each notch 15,16,28,29 these powder and granular material of guiding.Promptly, snap in powder and granular material midway at each notch 15,16,28,29, transfer valve 20A does not stop to move, and along these little circular arcs, this powder and granular material is guided to the direction of slip most external near side end and each notch 28,29 of each notch 15,16.
In addition, in the present embodiment, therefore each notch 15,16 of glide base 10 and each notch 28,29 of transfer valve 20A form step shape, can play to be equal to the effect that stage portion produced that above-mentioned first embodiment and second embodiment illustrate respectively.
In addition, as mentioned above, if the maximum width of each notch 15,16,28,29 of little circular shape becomes about 1/2～2 times of powder diameter of powder and granular material, then when snapping in the powder and granular material p of air conveying, snap in powder and granular material p in the mode that under overlooking, is housed in the notch 15,16,28,29, the upstream side peristome that snaps in side becomes the state that the occlusive part 23,24 that is switched valve 20A roughly stops up, and therefore can more effectively reduce the leakage of air amount in the peristome that snaps in side.
Especially, in the present embodiment, form the maximum width that the average powder diameter of the powder and granular material of carrying with air matches, when snapping in powder and granular material p, under overlooking, to be contained in fully between notch 16 and the notch 29, or the mode between notch 15 and the notch 28 snaps in powder and granular material p, thereby can more effectively reduce the leakage of air amount in the peristome that snaps in side.
