Description

  The present invention relates to a mat cleaning apparatus for cleaning a mat placed on a building passage, a stair landing, or a floor.

  Conventionally, a mat in which flocking is performed covering the surface of a flexible sheet is well known. This is called a foot-wiping mat or the like, and can adsorb sand, dust, or dirty water attached to the back of a passer's shoe by being entangled with the flocked hair. Therefore, since sand and the like gradually accumulate on the surface of the mat, regular cleaning is indispensable. The following patent documents disclose techniques related to mat cleaning.

JP 2003-190897 A (Patent No. 3546038) JP 2001-46990 A

  In order to wash the mat with water, water must be continuously sprayed at a water pressure high enough to extrude sand or the like that has entered the surface of the mat from the surface. In this case, a large and high-power pump that can pressurize a large amount of water at a time, or a large compressor is required, so that the entire cleaning device is inevitably increased in size. In order to further enhance the cleaning effect, a detergent may be used in combination. However, mass consumption of water, water contamination by detergents, or power consumption by the above-described compressor or the like is not preferable from the viewpoint of reducing environmental load.

  Accordingly, an object of the present invention is to provide a small mat cleaning apparatus that can efficiently clean a mat without using a detergent.

The present invention includes a carrying means for carrying the surface and flocked mat to the surface having a rear surface from scratch end, and unloading means for unloading from the other end of the mat is carried by該搬guide means, said carrying Conveying means for generating tension on the mat by setting the speed at which the carrying-out means carries out the mat faster than the speed at which the means carries the mat, and a swinging piece extending in the carrying direction in which the carrying means carries the mat but by repeatedly colliding with the back surface of the mat while moving up and down with the operation of the crank rocker by the rotating machine, a blow means for striking toward the back surface of the mat downward, the surface of the front Kemah Tsu DOO and a fountain means for fountain wash water, a luma Tsu preparative cleaning apparatus and a dewatering means for removing the wash water from the mat, the conveying means, one of the plurality of rollers spaced horizontally from each other The mat is carried in accordance with the rotation of the roller, the endless chain is wound around the sprockets provided on the plurality of rollers, and the other roller of the plurality of rollers is wound on the one roller. The diameter of each of the plurality of rollers so that the mat can be carried out according to the rotation of the other roller at a speed faster than the speed of the mat carried in accordance with the rotation of the one roller. Or the number of sprocket teeth of each of the plurality of rollers is different .

Furthermore, the present invention includes a rotating brush for sliding contact with the surface of the front Symbol mat, at a location opposing the front surface and the back surface of the mat you anda吹水means for respectively injecting air.

  Further, the present invention is characterized in that a dust collecting member is provided below the hitting means, and a water collecting member for collecting the washing water is provided below the fountain means, the rotating brush, and the water blowing means. And

  Furthermore, the present invention is characterized by comprising water supply means for circulating the wash water collected by the water collecting member and pumping the wash water to the fountain means, and purification means for purifying the wash water.

  According to the mat cleaning apparatus of the present invention, the conveying means directs the mat from one end to the other end, and the surface of the matted mat is directed downward in the course of the conveying, and the back surface of the mat in this posture is hitting means. Hits downward, so that the dust that has entered the surface of the mat can be knocked out of the surface, and at the same time, the dust can be dropped from the mat. In this way, the dust is expelled by mechanical impact, so the device is downsized by the amount that pumps or compressors are unnecessary compared to the conventional case of injecting water continuously at a high water pressure. can do. Moreover, excessive power consumption can be avoided. Further, there is an advantage that the dust once dropped from the mat does not adhere to the mat again.

  Furthermore, in the mat cleaning device according to the present invention, the hitting means, the fountain means, the rotating brush, and the water spray means are arranged in order from one end to the other end of the transport means, so that the hitting means generates sufficient dust. After the fountain means fountains the washing water onto the discharged mat surface, the rotating brush slides into contact with the mat surface.

  Since only the dust mainly composed of relatively small particles or light particles of specific gravity remains on the surface of the mat after being hit by the hitting means, such dust is washed water sprayed from the fountain means. Can be washed away easily. Moreover, even if dust adheres to or adheres to the surface of the mat, the dust is peeled off from the surface of the mat due to vibrations when the rotating brush slides on the surface of the mat at the same time that the rotating brush is scraped off. Can be subsidized.

  As described above, according to the device, dust can be removed efficiently without depending on the surface active action of the detergent, so there is no need to use any detergent and greatly contributes to the improvement of environmental problems due to water pollution. it can. Further, the water pressure at which the fountain means fountains the washing water does not need to be set so high that the sand dust that has entered the surface of the mat can be pushed out, so a high-power pump or a large compressor is not required. Therefore, as described above, it is possible to achieve downsizing and energy saving of the device.

  Subsequently, before the mat is carried out from the other end of the conveying means, the water blowing means injects air to the opposing portions of the front surface and the back surface of the mat, so that the washing water is blown off from the surface of the mat. The time required for the surface of the mat to dry after it is unloaded from the other end of the transport means can be shortened. At the same time, water droplets or dust scattered from the surface of the mat in the cleaning process described above may slightly adhere to the back surface of the mat, but such water droplets or dust are reliably removed from the back surface of the mat. can do.

  Furthermore, the mat cleaning device according to the present invention can, for example, rotate a roller made of a material excellent in water absorption to the surface of the mat, or suck the cleaning water that has permeated the surface of the mat using negative pressure. When the constructed dehydrating means is provided, the washing water can be positively removed from the mat conveyed to the other end of the conveying means. Thereby, after the mat is carried out from the other end of the conveying means, the time required for the mat surface to dry can be further shortened.

  Further, since the mat cleaning device according to the present invention is provided with the dust collecting member below the hitting means, when the mat is hit by the hitting means, the dust collecting member can receive the dust falling from the mat. . Moreover, since the water collecting member is provided below the fountain means, the rotating brush, and the water blowing means, the dust collected from the surface of the mat together with the washing water can be collected by the water collecting member. Accordingly, it is possible to easily dispose of only the sand dust while eliminating the trouble of separating the dust falling from the mat and the dust contained in the washing water.

  Further, according to the mat cleaning apparatus of the present invention, the cleaning water collected by the water collecting member is circulated by the water supply means and pumped to the fountain means. Therefore, when the mat is continuously cleaned, the fountain is applied to the mat. There is no need to discard the washed water and no need to replenish new wash water. Therefore, consumption of tap water etc. can be minimized. In addition, the cleaning means purifies the cleaning water in the process of circulating the cleaning water, so that there is an advantage that the dust once washed from the mat does not adhere to the mat again.

  Furthermore, according to the mat cleaning apparatus of the present invention, the speed at which the carry-out means carries out the mat from the other end is set faster than the speed at which the carry-in means carries the mat from one end. Generate and tension the entire mat. For this reason, even if the striking means strikes the mat at a high speed or the rotating brush comes into strong contact with the mat and the resistance to the mat is prevented, the mat is twisted during the cleaning process. There is no such thing. Therefore, it is possible to prevent the mat from being entangled with the striking means or the rotating brush, and to realize a stable operation of the apparatus.

The side view which shows the outline of the principal part of the mat | matte washing apparatus which concerns on embodiment of this invention. Schematic which shows the outline of the circulation route of the washing water applied to the mat washing | cleaning apparatus which concerns on embodiment of this invention.

  As shown in FIG. 1, the mat m handled in the embodiment of the present invention is obtained by using a flexible sheet having a front surface 1 and a back surface 2 as a base, and flocking the surface 1. Normally, the mat m is laid on the floor or the like with the back surface 2 facing downward. When the mat m is cleaned using the mat cleaning device 3, the front surface 1 is directed downward.

  The mat cleaning device 3 strikes the mat m with a conveying means 4 for conveying the mat m from one end (right side in the figure) to the other end (left side in the figure) of the housing not shown in the drawing and the back surface 2 of the mat m facing downward. Compressing the striking means 5, the fountain means 6 for spraying cleaning water on the surface 1 of the mat m, the rotating brush 7 slidingly contacting the surface 1 of the mat m, and the opposite surfaces of the surface 1 and the back surface 2 of the mat m And water blowing means 8 for injecting air.

  The transport means 4 includes a plurality of rollers 41 to 45 that are rotatably disposed in the housing so as to be horizontally spaced from each other. Further, all the other rollers 41 to 44 are driven by a roller 45 through an endless chain 46 made of a chain or the like. A pressure roller 47 that presses the back surface 2 of the mat m downward is disposed directly above each of the rollers 41, 43, and 45, and frictional force between the rollers 41, 43, and 45 and the surface 1 of the mat m is disposed. Therefore, the mat m can be reliably conveyed in accordance with the rotation of the roller 45. An arrow T indicates a transport direction in which the transport unit 4 transports the mat m. The roller 41 serves as a carrying-in means for carrying in the mat m from one end of the housing, and the roller 45 serves as a carrying-out means for carrying out the mat m carried in by the carrying-in means from the other end of the housing. .

  The striking means 5 has a swing piece 51 extending along the conveying direction of the mat m attached to the rotary shaft 52, for example, the crank swing arm G is connected to the hitting rotary machine M2, and the rotary shaft 52 is output by the output of the crank swing arm G. Are alternately rotated clockwise or counterclockwise in the figure. As the rotary shaft 52 moves, the swing piece 51 repeatedly collides with the back surface 2 of the mat m while moving up and down in small increments.

  Although only one swinging piece 51 appears in the drawing, in reality, the rotating shaft 52 has a shape extending in the width direction of the mat m (horizontal direction orthogonal to the conveying direction), and thus A plurality of oscillating pieces 51 that are spaced apart from each other in the width direction are attached to the rotating shaft 52. Similarly, a plurality of fountain means 6 and fountain means 8 are also arranged in the width direction.

  The fountain means 6 includes a cleaning nozzle 61 having a front end facing the back surface 2 of the mat m, and a water supply means 62 comprising a pump that draws the cleaning water from the water supply tank 9 shown in FIG. . The rotating brush 7 is provided with a brush 72 on the circumferential surface of a cylindrical body 71 extending in the width direction of the mat m, and the brush body of the brush 72 is brought into contact with the back surface 2 of the mat m so that the cylindrical body 71 is moved to the brush rotating machine M3. Rotate clockwise in the figure. The water blowing means 8 supplies the compressed air from a supply source 82 such as an air compressor to a pair of air nozzles 81 sandwiching the mat m from above and below and facing the respective front end ports, thereby providing a front surface 1 and a back surface of the mat m. 2 is used to inject compressed air.

  According to the mat cleaning device 3 described above, the striking means 5 strikes the back surface 2 of the mat m downward while the transport means 4 transports the mat m, so that it has entered the front surface 1 of the mat m. Dust can be knocked out of the mat m. In this way, the dust is expelled by mechanical shock, so compared to the conventional case where water is continuously injected at a high water pressure, a large pump or a large-scale compression to pump water strongly. No machine is required. Accordingly, the mat cleaning device 3 can be reduced in size, and excessive power consumption can be avoided. Further, since the dust once struck from the mat m falls from the mat m as it is, the dust does not adhere to the mat m again.

  Further, the striking means 5, the fountain means 6, the water blowing means 8, the rotating brush 7, and the water blowing means 8 are arranged in order from one end to the other end of the housing. After the fountain means 6 fountains the washing water onto the surface 1 of the mat m from which the dust has been discharged, the rotating brush 7 is brought into sliding contact with the surface 1 of the mat m. At this time, since the surface 1 of the mat m already hit by the striking means 5 is left with only dust mainly composed of relatively small particles or light particles of specific gravity, such dust is The washing water fountained from the fountain means 6 can be easily washed away. Moreover, even if the dust adheres to or adheres to the surface 1 of the mat m, the dust is generated by the vibration when the rotating brush 7 slides on the surface 1 of the mat m at the same time that the rotating brush 7 scrapes off. Peeling from the surface 1 of the mat m can be aided.

  Therefore, dust can be efficiently removed without depending on the surface active action of the detergent, so that no detergent is required. Further, the water pressure at which the fountain means 6 fountains the washing water is not so high as to allow the sand dust that has entered the surface 1 of the mat m to be pushed out, so that a high-power pump or a large compressor is not required.

  Subsequently, before the mat m is carried out from the other end of the conveying means 4, the water blowing means 8 injects the compressed air to the opposite portions of the front surface 1 and the back surface 2 of the mat m. After washing water is blown off from the surface 1 and the mat m is unloaded from the other end of the housing, the time required for the surface 1 of the mat m to dry can be shortened. At the same time, water droplets or dust scattered from the surface 1 of the mat m in the cleaning process described above may slightly adhere to the back surface 2 of the mat m. It can be reliably removed from the back surface 2.

  Further, although not shown in the figure, the mat cleaning device 3 is made of, for example, a material excellent in water absorption, in order to positively remove moisture from the mat m blown off the cleaning water by the water blowing means 8. And a dehydrating unit configured to rotationally contact the roller 1 with the surface 1 of the mat m. Or you may comprise so that the washing water which permeate | transmitted the surface 1 of the mat m can be attracted | sucked using a negative pressure.

  Further, since the mat cleaning device 3 is provided with the dust collecting member 10 below the hitting means 5, the dust collecting member 10 receives the dust falling from the mat m when the hitting means 5 hits the mat m. Furthermore, dust can be collected by the dust collector 11. Moreover, since the water collecting member 12 is provided below the fountain means 6, the rotating brush 7, and the water blowing means 8, the water collecting member 12 collects dust washed away from the surface 1 of the mat m together with the washing water. It is done. Accordingly, it is possible to easily dispose of only the dust collected in the dust collector 11 while saving the trouble of separating the dust falling from the mat m and the dust contained in the washing water.

  On the other hand, the wash water collected by the water collecting member 12 is once sent to the water supply tank 9 by the pump 13, but is again sent to the fountain means 6 by the water supply means 62. Since the washing water can be circulated in this way, when washing the mat m continuously, the washing water sprayed on the mat m is not discarded and it is not necessary to supply new washing water. Therefore, consumption of tap water etc. can be minimized. Moreover, in the process of circulating the cleaning water, the cleaning water can be purified using, for example, the purifying means 14 based on the principle of the cyclone and the filter not shown in the figure, so that the dust once washed away from the mat m is again in the mat m. It will not adhere to.

  Further, it is desirable that the speed at which the roller 43 or the roller 45 (unloading means) unloads the mat m is faster than the speed at which the roller 41 (loading means) loads the mat m. Such a speed difference can be set, for example, by changing the diameters of the individual rollers 41, 43, 45, or by changing the number of teeth of the sprockets around which the endless chain 46 is wound around the rollers. . As a result, tension can be generated in the mat m and the entire mat m can be tensioned. For example, the striking means 5 strikes the mat m at high speed, or the rotating brush 7 strongly contacts the mat m. The mat m is not twisted even if a resistance to prevent the conveyance of the mat m is applied to the mat m. Therefore, it is possible to prevent the mat m from being entangled with the striking means 5 or the rotating brush 7.

  It should be noted that the present invention can be implemented in variously modified, modified, or modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, each of the hitting means 5, the fountain means 6, the water blowing means 8, the rotating brush 7, and the water blowing means 8 is illustrated as one, but any one or all of these may be increased to two or more. good.

  The mat cleaning apparatus according to the present invention is useful for cleaning a mat placed on a front door of a home in addition to a mat placed in a wide area such as a store or a public facility. Further, since the mat cleaning device is small and can be mounted on a truck or the like, the mat can be easily cleaned by traveling to the site where the mat is laid.
