Definitions

  • This invention relates to a dust removing system.
  • a dust removing system which can remove adhesive dust, dust stuck in a base member, sticky dust such as feather-like fiber at an edge portion of a base member of, for example, paper or films as well as dust on surface of a base member of such as paper or films is required.
  • a conventional dust removing system is disclosed in EP 0 640 411.
  • the dust removing system disclosed here has a casing having an air discharging chamber and an air sucking chamber and provided with a first jetting nozzle and a second jetting nozzle on the underside thereof. The first jetting nozzle and the second jetting nozzle blow supersonic jets such that these approach each other.
  • a sucking nozzle is located between the first jetting nozzle and the second jetting nozzle to allow the working air to be sucked into the casing.
  • FIG. 11 Another conventional dust removing system for adhesive dust is, as shown in Fig. 11, provided with a dust removing head 103 comprising a rotating brushroll 101 which slides on a travelling work 105 (a base member) and an air sucking chamber 102 possessing said brushroll 101 therein.
  • Dust removing systems of that kind are, for example, disclosed in the patent specifications US 4,996,746 (Flat cleaning apparatus for a card) and CH 654753 (Method and apparatus for cleaning the periphery of a cylindrical filter element).
  • FIG 1 and Figure 2 are showing an embodiment of a dust removing system, and this dust removing system is possessed with a dust removing head 1, a blower unit (not shown) and a traveler means (not shown) which makes work 2 traverse toward arrow A as the work 2 is arranged to be close to the head 1.
  • the dust removing head 1 is comprising an air sucking chamber 4 having an air sucking opening 3 which opens at a position near the work 2, a rotating brushroll 5 disposed inside the air sucking chamber 4 slidable on the work 2, and a nozzle 6 which sucks and removes dust R adhered to the rotating brushroll 5.
  • the dust removing head 1 possesses a casing 7 which is long in a width direction of the work 2, and inside the casing 7 the air sucking chamber 4 is formed corresponding to a substantially whole longitudinal length of the casing 7.
  • the slit-like air sucking opening 3 having a longitudinal length L longer than a width Wa of the work 2 is formed.
  • One end of an air sucking passage not shown in the attached drawings is connected to the air sucking chamber 4, and a blower unit which sucks air in the air sucking chamber 4 is connected to other end of the air sucking passage.
  • a blower unit which sucks air in the air sucking chamber 4 is connected to other end of the air sucking passage.
  • the rotating brushroll 5 is provided to be rotatable on axis M which is parallel to the slitted air sucking opening 3 inside the air sucking chamber 4 of the casing 7, and the brushroll 5 is rotated by a rotation driving means not shown in the attached drawings toward arrow F in Figure 1. With this rotating brushroll 5, the dust R adhered to a surface of the work 2 is wiped off.
  • Nozzle 6 is stuck to an under surface of a partition wall 8 which is provided above the brushroll 5 in the air sucking chamber 4.
  • the nozzle 6 has a slit hole 10 extended corresponding to a whole axial length of the brushroll 5.
  • the nozzle 6 is possessed with a pair of blade portions 21 having concave face portions 20 which are formed on edges of end portions of outer faces thereof. Tip portions of the blade portions 21 are tip thin portions 22. Between inner faces of the pair of blade portions 21 opposing each other, a slit hole 10 extended corresponding to the whole axial length of the axis M of the brushroll 5 is formed.
  • An end of nozzle 6 extended corresponding to the whole axial length of the axis M is arranged to be close to or contact with a circumferential face of the brushroll 5.
  • a plurality of air passage slits 9 are provided on the partition wall 8 in the air sucking chamber 4, and one of said air passage slits 9 communicates the slit hole 10 of the nozzle 6.
  • a diameter D of the rotating brushroll 5 and an inner width W parallel to a traveling direction of the work 2 of the air sucking chamber 4 are arranged to be D ⁇ W ⁇ (D+20mm). Therefore a space between the rotating brushroll 5 and an inner wall surface of the air sucking chamber 4 is possible to be smaller, and air inside the air sucking chamber 4 can flows at high speed, hereby dust R sucked in the air sucking chamber 4 can quickly flow into the air sucking passage, and the dust R can be prevented not to remain in the air sucking chamber 4, and readhering of the dust R to the work 2 can be also prevented.
  • the diameter D and the inner width W are arranged to be (D+3mm) ⁇ W ⁇ (D+10mm), and the air inside the air sucking chamber 4 flows still more smoothly and at higher speed than the case arranged to be D ⁇ W ⁇ (D+20mm), therefore a possibility of the dust R remaining in the air sucking chamber 4 can be prevented.
  • D > W the brushroll 5 contacts the inner wall surface of the air sucking chamber 4, and no space exist between the brushroll 5 and the inner wall surface of the air sucking chamber 4. Therefore a velocity of the air flow inside the air sucking chamber 4 is considerably lowered and power of sucking dust R of the dust removing head 1 will lose.
  • W > (D+20mm) a space between the brushroll 5 and the inner wall surface of the air sucking chamber 4 becomes too large, and a velocity of the air flow inside the air sucking chamber 4 becomes lower.
  • Air passes between divisional walls 11 which form an air sucking opening 3 and a work 2 is arranged to be at a velocity V of 50 to 60 m/s. Therefore dust R is removed from the work 2 still more effectively and is sucked into the air sucking chamber 4 for certain. Furthermore dust R adhered to a work 2 which is difficult to be exfoliated depending on quality of a material of the work 2 by a conventional dust removing system is possible to be removed with the dust removing system of the present invention in some cases.
  • a velocity of air flow V is arranged to be below 50 m/s, dust R swept out by the brushroll 5 is possible to go outside through a space between partition walls 11 and a surface of the work 2. Even if a velocity of air flow V is more than 60 m/s, an efficiency of removing dust R does not change very much.
  • a rotating brushroll 5 is arranged to rotate within a range of 1600 to 3000 r.p.m.. Therefore dust R adhered to the work 2 is effectively removed and a possibility of the work 2 to be scratched by the brushroll 5 can be prevented. If rotation of the brushroll 5 is below a range of 1600 r.p.m., dust R stuck strongly to the work 2 may not be removed in some cases. If rotation of the brushroll 5 is above a range of 3000 r.p.m., a surface of work 2 is possible to be scratched and damaged by the brushroll 5.
  • a length B of bristle end portions 12a among brush bristles 12 of said rotating brushroll 5 contactable to the surface of the work 2 and a thickness T of said work 2 are arranged to be 0 ⁇ B ⁇ T. Therefore while this dust removing system is working, as shown in Figure 5, each of the brush end portions 12a slides surely on the surface of the work 2 in a condition that the brush bristle 12 is slightly bent and is moderately stored elastic energy. For this reason dust adhered to the work 2 is removed still more surely, and the work 2 can be prevented to be damaged. If a length B of the bristle end portion 12a is arranged to be 0 > B, i.e.
  • the brushroll 5 will not have a function of removing dust. If B > T, the brush bristle 12 bends largely and hits and scratches the surface of the work 2 hardly.
  • dust R adhered to the work 2 is removed surely and efficiently by the rotating brushroll 5 of the present dust removing system. Moreover dust R adhered to the brushroll 5 is removed by applying the nozzle 6, and the dust R adhered to the work 2 again which is removed once from the work 2 is possible to be prevented. Especially, for example, sticky dust, dust stuck in the work 2, fluff of the end rim of the work 2 (in case the work 2 is paper) are removed effectively.
  • the dust removing head 1 of the dust removing system can be prevented to be dirty. That is to say, a space between the rotating brushroll 5 and an inner wall surface of an air sucking chamber 4 becomes smaller than that of the conventional dust removing system, and air inside the air sucking chamber 4 flows at high speed and dust R sucked in the air sucking chamber 4 can quickly flow into the air sucking passage. Therefore the dust R is prevented not to remain in the air sucking chamber 4 after an operation of the dust removing system. That is to say, the dust R is prevented not to remain in the rotating brushroll 5 and the inner wall surface of the air sucking chamber 4. Therefore the dust removing head 1 can be used for a long term without cleaning, and a frequency of cleaning and exchanging of the brushroll 5 can be decreased. In consequence, maintenance of the dust removing system would be easy and a running cost would be decreased at the same time.
  • the brush bristle 5 can be made of, for example, polyamide resin, acrylic resin, metal, conductive fiber, but it is possible to be made of other materials.
  • the work 2 which dust is removed therefrom can be, for example, paper, film or other materials.
  • FIG. 6 shows another embodiment of a dust removing system.
  • This dust removing system possesses first and second air discharging chambers 15, 16 arranged on an upstream side H and a downstream side J of an air sucking opening 3 of an air sucking chamber 4 and are provided with first and second ultrasonic nozzles 13, 14 which respectively change air to air knife K including ultrasonic pressure wave P and blow the air knife K against said work 2.
  • Divisional walls 11 divide inside a casing 7 of a dust removing head 1 into the air sucking chamber 4 and the first and second discharging chambers 15, 16 on the upstream side H and the downstream side J of said air discharging chamber 4. Structures of rest of parts of this embodiment are almost same as those shown in Figure 1 to 5.
  • the first and second air discharging chambers 15, 16 are provided with air from a blower unit not shown in the attached drawings through an air discharging passage not shown in the attached drawings.
  • the air passes the first and second ultrasonic nozzle 13, 14, and becomes air knife K including ultrasonic pressure wave P and blown against a work 2. After that the air knife K is sucked in the air sucking chamber 4 together with the dust R, and the air goes back to said blower unit through an air sucking passage.
  • an ultrasonic pressure wave P destroys a boundary layer 25 and an air knife K directly hits a surface of a work 2 and dust R can be exfoliated effectively. Therefore two kinds of dust removing operation which are of the brushroll 5 and of the air knife K including the ultrasonic pressure wave P, the dust R adhered to the work 2 can be removed still more surely. Especially, for example, adhesive dust, dust stuck in the work 2, fluff on an end rim of the work 2 (if the work 2 is paper) are removed effectively.
  • FIG 9 shows further embodiment of a dust removing system.
  • the dust removing system possesses an air sucking chamber 17 arranged on a downstream side J of an air sucking chamber 4, and first and second air discharging chambers 15, 16 arranged on the downstream side J of said air sucking chamber 4 and provided with first and second ultrasonic nozzles 13, 14 which blow air knife K including ultrasonic pressure wave P against a work 2 on an upstream side H and a downstream side J of said air sucking chamber 17.
  • the dust removing system is constructed as described above, after exfoliated adhesive dust R stuck to the work 2 with the brushroll 5 in the air sucking chamber 4 on the upstream side H of the air sucking chamber 4, the air knife K including the ultrasonic pressure wave P blown from the first and second ultrasonic nozzles 13, 14 on the downstream side J of the air sucking chamber 4 is possible to strongly suck and remove dust R remained in the work 2.
  • the dust R adhered to the work 2 is removed by two steps of dust removing operations which are operations of the brushroll 5 and the air knife K on the downstream side of the air sucking chamber 4 including the ultrasonic pressure wave P. The dust can be removed still more surely by two steps of the dust removing operation.
  • FIG 10 shows a dust removing system according to the present invention.
  • a casing 7 is possessed with partition walls 11 wherein (for example) blade edge portions 30 having triangular cross sections are obliquely formed on lower end edges thereof (as shown in Figure 10), and a gap between the lower end edge of the partition wall 11 (i.e. the blade edge portion 30) and (an outer circumferential face of) the brushroll 5 is reduced. Therefore a velocity of air flows in the gap between the lower end edge of the partition wall 11 (i.e. the blade edge portion 30) and the outer circumferential face of the brushroll 5 is increased, and fine dust R separated from the surface of the work 2 can be sucked into the air sucking chamber 4 for certain.
