The specific embodiment
(roll feedway)
Roll feedway of the present invention and carrying method are described below with reference to the accompanying drawings.
Fig. 3 is the instruction diagram of air flow condition of the air supporting roller section of expression roll feedway of the present invention.
Specifically, be provided with the plate 26 of becalming being included in the opposition side of a side of circumvolution roll 25 of air supporting roller that cylindric surface is provided with urceolus 21, air fed inner core 22, the edge rollers 24 of the squit hole that is used to spray air.By adopting this structure, the air-flow that downward direction flows out among the figure flows and flows to the left and right along the Width of roll 25.Like this, in the downflow system Clean room, airflow flowing is with from up to down airflow flowing is mobile to the left and right.Thus, the generation of the eddy current that produces by air-flow etc. can be reduced with doing one's utmost, dust adhering to can be reduced to roll 25 surfaces.
Be described in more detail according to Fig. 4, Fig. 5.Fig. 4 represents the block diagram of roll feedway of the present invention, and Fig. 5 represents section-drawing.The air supporting roller comprises inner core 22, urceolus 21 and not shown edge rollers.Inner core 22 is a hollow shape, is formed with a plurality of squit holes around it.Not shown axle support fixed bearing is passed through at the both ends of this inner core 22, and linking respectively at its both ends has not shown air supplying tubing.In addition, urceolus 21 also is columnar hollow shape, and portion contains inner core 22 within it.Surface at the cylindrical shape conveyor surface of this urceolus 21 (face that is covered by roll when carrying roll) is formed with a plurality of air squit holes.
Bottom at this air supporting roller is fixed with the plate 26 of becalming by not shown supporting mass.This length of becalming plate 26 its roll 25 Widths forms narrower than roll 25 width, or the length of its roll 25 direct of travels forms roughly the same length with two intervals near roller 23 that are arranged at the front and rear of air supporting roller.In addition, the air supporting roller is preferably 10～100 (mm) with the distance H of the plate 26 of becalming, and has confirmed that in the experiment that the inventor did the plate 26 of then becalming can not contact with roll 25, and can control dust adhering to roll as long as in this distance range.In addition, are shapes roughly the same near roller 23 with the air supporting roller, support its two ends axial region freely by not shown bearing rotation, and the upper surface of roll 25 is contacted supporting.
In the roll feedway of above structure, when supplying with pressurized air from inner core 22 two ends of air supporting roller, this pressurized air from the not shown air squit hole that is formed at inner core 22 to the ejection of the outside of inner core 22.The air of this ejection further sprays to the outside from the air squit hole that is arranged at urceolus 21, utilizes the air of this ejection that roll 25 is floated conveying.
In addition, when carrying roll 25, therefore the upper surface near roller 23 supporting rolls 25 of the front and rear by being arranged at the air supporting roller, can make the floatation volume of roll 25 of conveyor surface of urceolus 21 of air supporting roller stable.
In above structure, the air that sprays from air supporting roller urceolus 21 squit holes floats roll 25 in the direction that has roll 25, but air forms airflow flowing in the direction that does not have roll 25.On the other hand, never exist the air former state of squit hole ejection of the urceolus 21 of roll 25 to flow out.
Therefore, the air that sprays from the squit hole that is arranged at air supporting roller urceolus 21 is formed on the direction airflow flowing that does not have roll 25.In roll feedway of the present invention, this air communication is crossed the direction that the plate 26 of becalming that is arranged at air supporting roller bottom is changed air current flow, becomes at the air supporting roll shaft to being roll 25 Width airflow flowing.Afterwards, this air-flow flows out to the outside around the air supporting roller, and with airflow flowing interflow in the Clean room, dust that will swim in air-flow and air-flow are transported to the place of leaving roll 25 together, thereby can prevent that it is attached on the roll 25.
More than, in the structure of roll feedway of the present invention, the air-flow in the Clean room can not produce disorder, can prevent dust adhering to roll 25 with simple structure.
At this, except the setting of above-mentioned explanation is becalmed the roll feedway of structure of plate 26 monomers, by adopting following structure the flow adjustment of air-flow can be become best flowing, described structure is as shown in Figure 6 at the air supporting roller that is made of urceolus 22 and inner core 22 and becalm the structure of surface plate 27 is set between the plate 26 in addition; As shown in Figure 7 at the air supporting roller that constitutes by urceolus 22 and inner core 22 and becalm the structure of snyed plate 28 is set between the plate 26; And as shown in Figure 8 at the air supporting roller that constitutes by urceolus 22 and inner core 22 and becalm between the plate 26 structure of the breaker plate 29 that is made of porous body is set.
In addition, as shown in Figure 9, the reason that the distance H of the above-mentioned air supporting roller and the plate 26 of becalming is preferably 10～100 (mm) is, when distance H when 100 (mm) are above, when then air-flow contacts with the plate 26 of becalming, air-flow changes the flow direction in the direction vertical with respect to the face of the plate 26 of becalming, and thus, adheres to dust sometimes on roll 25.On the contrary, when 10 (mm) are following, when the variation because of air pressure or conveyance tension makes roll 25 vibration, because of contacting with the plate 26 of becalming etc., roll 25 causes the bad of roll 25 sometimes.In sum, the air supporting roller is preferably 10～100 (mm) with the distance H of the plate 26 of becalming.
In addition, under roll feedway of the present invention is arranged at situation in the downflow system Clean room, the width of roll 25 Widths of plate 26 of preferably becalming is narrower than the width P of roll 25, and wideer than the interval S of the edge rollers 24 that is arranged at air supporting roller both sides.Adopt the width of this scope, then the air from 21 ejections of air supporting roller urceolus can directly not flow with strong air quantity downward direction, produces eddy current thereby can reduce air-flow, in addition, can not hinder airflow flowing in the Clean room.
