Detailed Description
Hereinafter, preferred embodiments of the membrane cleaner of the present invention will be described in detail with reference to the accompanying drawings. The terms or words used below are not limited to the conventional meanings or the meanings in the dictionary, and should be interpreted as the meanings and concepts conforming to the technical idea of the present invention, on the basis of the principle that the inventor can appropriately define the concept of the terms in order to explain his invention in the best way.
The membrane cleaner 100 according to the present invention winds around the roller 10 and removes foreign substances attached to the surface of the membrane 20 moving from the rear to the front by air, as shown in fig. 1, and includes a cleaner head 110, an air supply pipe 210, and an air suction pipe 220.
The air supply pipe 210 is used to supply air, which is sprayed toward the surface of the membrane 20, to the cleaner head 110, and is connected to the left side plate 128a of the cleaner head 110. In the present embodiment, two gas supply pipes 210 are provided. And the suction pipe 220 for sucking the air injected toward the surface of the membrane 20 and the foreign substances separated from the surface of the membrane 20 by the air is connected with the right side plate 128b of the cleaner head 110. Of course, the air supply pipe 210 may be connected to the right side plate 128b, and the air suction pipe 220 may be connected to the left side plate 128 a.
The cleaner head 110 is a member extending in the width direction (left-right direction) of the film 20, and has facing surfaces 122, 132, 142, 174, and 184 facing the film 20. As shown in fig. 2, when the film cleaner 100 is disposed under the roller 10 that moves so as to wrap the film 20, the facing surfaces 122, 132, 142, 174, and 184 are located under the film 20 with a predetermined distance from the film 20.
As shown in fig. 1 to 3, such a cleaner head 110 includes a center block 120, a front block 130, a rear block 140, and a plurality of double bolts 160.
The center block 120 is a block formed to extend in the left-right direction at the center of the cleaner head 110, and has a facing surface center portion 122 as a center portion of the facing surfaces 122, 132, 142, 174, and 184. The left and right side plates 128a and 128b are fastened to the left and right ends of the center block 120 by bolts 129.
The center block 120 has discharge holes 122a and 124 extending in the left-right direction at the center. In the present embodiment, the discharge holes 122a and 124 are formed by a long hole 122a extending in the left-right direction at the center portion 122 of the facing surface, and an internal space 124 formed inside the center block 120 so as to be located at a lower portion of the long hole 122a and communicating with the long hole 122 a. The air jetted toward the surface of the film 20 and the foreign substances separated from the surface of the film 20 by the air are discharged through the discharge holes 122a and 124. On the other hand, the portion of the facing surface center portion 122 located around the elongated hole 122a is formed by the concave surface 122b having a larger curvature (i.e., a smaller curvature radius) than the facing surface center portion 122, which facilitates all foreign matters separated from the surface of the film 20 to be promptly discharged through the discharge holes 122a, 124.
Further, the center block 120 has an exhaust passage 126 extending in the left-right direction from the lower portion of the exhaust holes 122a, 124, more specifically, from the lower portion of the internal space 124. The discharge duct 126 communicates with the discharge holes 122a and 124 through a plurality of communication holes 124a formed in the bottom surface of the internal space 124, and communicates with the intake pipe 220. And the left and right ends of the exhaust duct 126 are blocked by the left and right side plates 128a and 128 b. Thus, when the intake pipe 220 performs intake, the air injected toward the film 20 and the foreign substances separated from the surface of the film 20 are drawn into the intake pipe 220 through the discharge holes 122a and 124 and the exhaust passage 126.
The front block 130 is a member having a facing surface front portion 132 located in front of the facing surface center portion 122, and extends in the left-right direction between the left side plate 128a and the right side plate 128 b. The front block 130 faces the front surface of the center block 120, and a slit-shaped gap extending in the left-right direction between the facing surface center portion 122 and the facing surface front portion 132 is formed, and the slit-shaped gap also serves as a nozzle 150 for ejecting air onto the surface of the film 20.
The rear block 140 is a member having a facing surface rear portion 142 located rearward of the facing surface center portion 122, and extends in the left-right direction between the left side plate 128a and the right side plate 128 b. The rear block 140 faces the rear surface of the center block 120, and a slit-shaped gap extending in the left-right direction between the facing surface center portion 122 and the facing surface rear portion 142 is formed, and the slit-shaped gap also serves as a nozzle 150 for ejecting air onto the surface of the film 20.
When the front block 130 and the rear block 140 face the front surface and the rear surface of the center block 120, an air supply passage 154 is formed between the front block 130 and the rear block 140 and the front surface and the rear surface of the center block 120, and an airtight member 152 is inserted. The air supply duct 154 extends in the left-right direction so that the air supply pipe 210 communicates with the nozzle 150. Whereby the air supplied from the air supply pipe 210 is sprayed to the surface of the membrane 20 through the air supply passage 154 and the nozzles 150. The air-tight member 152 is positioned on the opposite side of the nozzle 150 with respect to the air supply passage 154 and extends in the left-right direction. Whereby air of the air supply passage 154 is injected only through the nozzle 150 without leaking to the opposite side of the nozzle 150. Fig. 2 and 3 show an example in which grooves are formed in the front and rear surfaces of the center block 120 to form the air supply passage 154 and to insert the air-tight member 152.
The plurality of double bolts 160 are members having a function of fixing the front block 130 and the rear block 140 to the center block 120 and a function of uniformly forming the front-rear direction width of the nozzle 150 along the entire length in the left-right direction, and are arranged in the left-right direction in the front block 130 and in the left-right direction in the rear block 140. Each double bolt 160 is composed of an outer bolt 162 and an inner bolt 164.
The outer bolt 162 is screwed to the front block 130 and the rear block 140, and is fastened to the front block 130 and the rear block 140 so as to penetrate the front block 130 and the rear block 140. The ends of the outer bolts 162 fastened to the front block 130 and the rear block 140 are in contact with only the front and rear surfaces of the center block 120 and are not screwed together. Accordingly, after all the outer bolts 162 are fastened to the front block 130 and the rear block 140, the front block 130 and the rear block 140 are placed so that the end portions of the plurality of outer bolts 162 are in contact with the front surface and the rear surface of the center block 120, and thereby the front-rear direction width of the nozzle 150 formed between the facing surface center portion 122 and the facing surface front portion 132 and the rear portion 142 becomes uniform along the entire length in the left-right direction.
The inner bolt 164 is screwed to the outer bolt 162 and is fastened to the outer bolt 162 so as to penetrate the outer bolt 162. The inner bolt 164 penetrating the outer bolt 162 is also screwed into the screw grooves formed on the front and rear surfaces of the center block 120. Therefore, after all the inner bolts 164 are fastened, all the outer bolts 162 fastened to the front block 130 and the rear block 140 are fixed to the center block 120, whereby the front-rear direction width of the nozzle 150 is maintained in an original uniform state along the entire length in the left-right direction and the front block 130 and the rear block 140 are also fixed to the center block 120.
On the other hand, the cleaner head 110 further includes a front cover 170, a rear cover 180, and a sound absorbing material 190.
The front cover 170 is coupled to one surface of the center block 120 by a plurality of bolts 172 to be positioned in front of the front block 130, and left and right ends of the front cover 170 are coupled to the left and right side plates 128a and 128b by bolts 129. And the rear cover 180 is coupled to one surface of the center block 120 by a plurality of bolts 182 to be positioned at the rear of the rear block 140, and left and right ends of the rear cover 180 are coupled to the left and right side plates 128a and 128b by bolts 129.
The front cover 170 and the rear cover 180 have facing surface forming portions 174 and 184 constituting a part of the facing surfaces 122, 132, 142, 174, and 184, the facing surface forming portion 174 of the front cover 170 is positioned in front of the facing surface front portion 132, and the facing surface forming portion 184 of the rear cover 180 is positioned behind the facing surface rear portion 142.
The front cover 170 and the rear cover 180 surround a predetermined space filled with a sound absorbing material 190 together with the front block 130, the rear block 140, and the center block 120, as shown in fig. 2. The sound absorbing material 190 absorbs noise generated inside the cleaner head 110 due to the flow of air, thereby being capable of reducing noise generated in the cleaner head 110 when the membrane cleaner 100 is used.
As shown in fig. 1 and 2, a plurality of exposure holes 176 and 186 are formed in the facing surface forming portions 174 and 184 of the front cover 170 and the rear cover 180, and the sound absorbing material 190 is exposed from the gaps between the film 20 and the facing surfaces 122, 132, 142, 174, and 184 through the plurality of exposure holes 176 and 186. Thus, noise generated by the air flow in the gaps between the film 20 and the facing surfaces 122, 132, 142, 174, 184 is also absorbed by the sound-absorbing material 190 and reduced.
On the other hand, a sound absorbing material 190a may be additionally provided at the exhaust passage 126 of the center block 120, and the sound absorbing material 190a may be provided at the front and rear without obstructing the flow of air in the exhaust passage 126, as shown in fig. 2. And a pair of clamps 192 of the same form are provided in the center of the exhaust duct 126 in a left-right direction separated manner so that the sound absorbing material 190a separated in the front-rear direction is pressurized in the front-rear direction. Such sound absorbing material 190a does not at all impede the flow of air in the exhaust passage 126 and will absorb noise generated in the exhaust passage 126, thereby helping to reduce noise generated in the cleaner head 110 when the membrane cleaner 100 is in use.
As shown in fig. 4, each jig 192 includes a bracket 194 extending in the left-right direction, a pair of supports 194a bent forward and backward respectively are formed at the lower end of the bracket 194, and a bolt hole 194b is formed in at least one of the plurality of supports 194 a. A bolt (not shown) passing through the bolt hole 194b is fastened to the bottom surface of the exhaust passage 126, thereby fixing the bracket 194.
A blade member 196 extending in the front-rear direction is fixed to the upper end of the bracket 194, and a pressing member 198 extending in the left-right direction is fixed to the front-rear end of the blade member 196. The sound absorbing material 190a provided separately in the front and rear of the exhaust passage 126 is pressurized in the front and rear directions by the above-described pressurizing member 198.
The case where the above jig 192 is provided with two jigs separately provided in the left-right direction is described as an example. The two clamps 192 may be connected as a single body. The shape of the jig 192 may be different from the above-described one, and the sound absorbing material 190a may be provided so as to be separable in the front-rear direction by being pressed in the front-rear direction.
On the other hand, when the membrane cleaner 100 is started in a state where the preparation for movement of the membrane 20 is completed, air is supplied to the air supply pipe 210 and air is sucked into the air suction pipe 220. After that, the membrane 20 moves, and then the air of the air supply pipe 210 is sprayed to the surface of the membrane 20 through the air supply passage 154 and the nozzle 150, and the foreign substances are separated from the surface of the membrane 20, and the sprayed air and the separated foreign substances are sucked into the air suction pipe 220 through the discharge holes 122a and 124 and the air discharge passage 126.
In the above process, noise generated in the cleaner head 110 due to the flow of air and noise generated in the gaps between the membrane 20 and the facing surfaces 122, 132, 142, 174, 184 are absorbed by the sound absorbing materials 190, 190a, thereby reducing noise generated when the membrane cleaner 100 operates significantly.
As described above, although the present invention has been described with respect to the limited embodiments and the accompanying drawings, the present invention is not limited thereto, and a person having ordinary skill in the art to which the present invention pertains can make various modifications and variations without departing from the technical spirit of the present invention and the equivalent scope of the claims described below, and various combinations of the above-described embodiments can be made.
