Description

  The present invention relates to a cleaning device and a cleaning method for cleaning dust adhering to a surface to be cleaned.

  As a method for cleaning dust adhering to the surface to be cleaned, such as toner adhering to the corrugated cardboard, either a method of scattering dust with an air blow or a method of sucking and collecting with a vacuum cleaner can be used.

  In the method of scattering by air blow, it takes time and effort to collect the scattered dust. In order to save this effort, an apparatus for capturing scattered dust is required, but the apparatus becomes large and equipment costs increase (see, for example, Patent Document 1).

Also, with the method of sucking and collecting dust with a vacuum cleaner, the dust does not scatter, so you can save time after cleaning the surface to be cleaned, but only a small area of dust facing the suction port of the vacuum cleaner. Since it cannot be inhaled, the cleaning work itself takes time.
JP 2004-261712 A

  The present invention has been made in consideration of the above-described facts, and it is an object of the present invention to clean the dust adhered to the surface to be cleaned without scattering and to shorten the cleaning time.

  The cleaning device according to claim 1 is a cleaning device that sucks dust adhering to a surface to be cleaned, the sheet material covering and closely contacting the surface to be cleaned, and suction between the surface to be cleaned and the sheet material A suction nozzle that is inserted with the mouth sideways and is slid on the surface to be cleaned, and a suction unit that sucks dust adhering to the surface to be cleaned from the suction nozzle.

  In the cleaning device according to claim 1, the sheet material covers and closely contacts the surface to be cleaned to which dust adheres, and the suction nozzle is inserted between the surface to be cleaned and the sheet material with the suction port facing sideways. . The suction nozzle is slid between the surface to be cleaned and the sheet material, and dust attached to the surface to be cleaned is sucked from the suction nozzle by the suction means.

  Here, since the suction nozzle is inserted between the surface to be cleaned and the sheet material with the suction port facing sideways, the upper surface of the suction nozzle and the surface of the suction nozzle are sucked by the suction force from the suction port in front of the suction port. It is brought into close contact with the cleaning surface, and the sealing performance between the sheet material, the surface to be cleaned, and the suction nozzle is increased. As a result, an air flow path directed only to the suction port is formed in front of the suction port.

  For this reason, since the suction force of the suction means acts on the surface to be cleaned without loss, the dust adhering to the surface to be cleaned can be suctioned vigorously. In addition, a wide range of dust can be sucked at once. Therefore, the cleaning time can be shortened.

  Further, since dust adhering to the surface to be cleaned can be sucked into the suction means without being scattered, it is not necessary to clean up the dust after cleaning the surface to be cleaned. Therefore, the number of work steps can be reduced and the equipment cost can be reduced.

  The cleaning device according to claim 2 is the cleaning device according to claim 1, wherein the suction nozzle is a slit in which the suction port extends along the surface to be cleaned.

  In the cleaning device according to the second aspect, the suction port of the suction nozzle is a slit extending along the surface to be cleaned. For this reason, the suction nozzle can be made thin, and the gap between the sheet material and the surface to be cleaned can be narrowed, so the suction force of the suction means acting between the sheet material and the surface to be cleaned is increased, The speed of sucking up dust increases. Therefore, the cleaning time can be shortened.

  The cleaning device according to claim 3 is the cleaning device according to claim 2, wherein the ratio A: B of the length A in the longitudinal direction and the length B in the short direction of the suction port is 20: 1 to 1. 150: 1.

  In the cleaning device according to claim 3, the ratio A: B of the length A in the longitudinal direction and the length B in the short direction of the suction port of the suction nozzle, which is a slit extending along the surface to be cleaned, is set to 20: 1. 150: 1. That is, the short direction length B is remarkably shortened with respect to the long direction length A. Thereby, since the sealing performance between the sheet material and the surface to be cleaned and the suction nozzle can be increased, the flow rate of air between the sheet material and the surface to be cleaned can be increased. Accordingly, the dust adhering to the surface to be cleaned can be suctioned vigorously, so that the cleaning time can be shortened. Further, dust can be prevented from scattering from between the sheet material, the surface to be cleaned, and the suction nozzle.

  A cleaning device according to a fourth aspect is the cleaning device according to any one of the first to third aspects, wherein the surface to be cleaned is a surface to which corrugated cardboard dust is attached.

  In the cleaning device according to the fourth aspect, the corrugated cardboard is covered with a sheet material so that the corrugated cardboard and the sheet material are in close contact with each other, and a suction nozzle is inserted between the corrugated cardboard and the sheet material. The suction nozzle is slid with the lower surface in close contact with the cardboard and the upper surface in close contact with the sheet material, and the suction means is activated. As a result, the dust adhering to the corrugated board covered with the sheet material can be sucked from the suction nozzle at a stroke, so the cleaning time of the corrugated cardboard with the dust attached can be shortened and the work of collecting the dust removed from the corrugated board can be eliminated. be able to.

  A cleaning device according to a fifth aspect is the cleaning device according to any one of the first to fourth aspects, wherein the thickness of the sheet material is 0.2 to 2.0 mm.

  In the cleaning apparatus according to the fifth aspect, the thickness of the sheet material that covers the surface to be cleaned is 0.2 to 2.0 mm. Here, when the sheet material is too thin, the sheet material is sucked into the suction port and the suction port is blocked by the sheet material, so that the dust attached to the surface to be cleaned cannot be sucked. When the sheet material is too thick, no suction force acts on the sheet material, and the sheet material is not in close contact with the surface to be cleaned, so that the suction force from the suction nozzle is weakened. Therefore, it is possible to satisfactorily absorb dust by setting the thickness of the sheet material to an appropriate thickness of 0.2 to 2.0 mm.

  A cleaning device according to a sixth aspect is the cleaning device according to any one of the first to fifth aspects, wherein the sheet material is urethane.

  In the cleaning device according to the sixth aspect, the material of the sheet material is urethane. Urethane has an appropriate strength and is not sucked into the suction port of the suction nozzle to close the suction port, so that the surface to be cleaned can be cleaned well.

  The cleaning method according to claim 7 is a cleaning method for sucking and cleaning dust adhering to the surface to be cleaned, covering the surface to be cleaned with a sheet material, bringing the sheet material into close contact with the surface to be cleaned, and suctioning While the nozzle is inserted between the surface to be cleaned and the sheet material with the suction port sideways and is slid on the surface to be cleaned, the suction means connected to the suction nozzle is operated to perform the cleaning. Dust adhering to the surface is sucked from the suction nozzle.

  The cleaning method according to claim 7, wherein the surface to be cleaned is covered with a sheet material, the sheet material is brought into close contact with the surface to be cleaned, the suction nozzle is set sideways and the surface to be cleaned and the sheet material are placed sideways. Insert between. Then, dust adhering to the surface to be cleaned is sucked into the suction means from the suction nozzle while sliding the suction nozzle between the surface to be cleaned and the sheet material.

  Here, since the suction nozzle is inserted between the surface to be cleaned and the sheet material with the suction port facing sideways, the upper surface of the suction nozzle and the surface of the suction nozzle are sucked by the suction force from the suction port in front of the suction port. It is brought into close contact with the cleaning surface, and the sealing performance between the sheet material, the surface to be cleaned, and the suction nozzle is increased. As a result, an air flow path directed only to the suction port is formed in front of the suction port.

  For this reason, since the suction force of the suction means acts on the surface to be cleaned without loss, the dust adhering to the surface to be cleaned can be suctioned vigorously. In addition, a wide range of dust can be sucked at once. Therefore, the cleaning time can be shortened.

  Further, since dust adhering to the surface to be cleaned can be sucked into the suction means without being scattered, it is not necessary to clean up the dust after cleaning the surface to be cleaned. Therefore, the number of work steps can be reduced and the equipment cost can be reduced.

  Since the present invention has the above-described configuration, cleaning can be performed without scattering dust adhering to the surface to be cleaned, and the cleaning operation time can be shortened.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, in this embodiment, the cleaning device 10 cleans the toner adhering to the cardboard D by sucking it. The cleaning device 10 includes a suction device 12 that sucks dust, a suction nozzle 16 attached to a tip end of a suction hose 14 of the suction device 12, and a sheet material 18 that covers the cardboard D.

  The suction device 12 is the same as a normal suction-type vacuum cleaner, but the suction nozzle 16 and the sheet material 18 are jigs created exclusively in the present embodiment. The size of the cardboard D is 80 cm in length to 100 cm in width.

  The cardboard D is placed on the table 20 with the cleaning surface facing upward, and the sheet material 18 is placed on the cardboard D. The size of the sheet material 18 is 100 cm long to 120 cm wide and slightly larger than the cardboard D in the vertical and horizontal directions, and the sheet material 18 is set so as to cover the entire surface of the cardboard D. The sheet material is urethane and has a thickness of 0.25 mm. However, the material may be other plastics such as vinyl chloride, and any material having a thickness of 0.2 to 2 mm is applicable.

  A fixing member 22 is placed on one end of the corrugated board D and the sheet material 18 in the longitudinal direction. The fixing member 22 is a square member that is heavy and cannot be overturned, and fixes one end side in the longitudinal direction of the corrugated cardboard D and the sheet material 18 (hereinafter referred to as a fixing side).

  The suction nozzle 16 is a thin and hollow trapezoidal columnar solid. The suction nozzle 16 includes trapezoidal side surfaces 16A and 16B opposed to each other, and the tip of the suction hose 14 is attached to one of the side surfaces 16A. The suction nozzle 16 includes rectangular side surfaces 16C and 16D opposed to each other with the side surfaces 16A and 16B interposed therebetween, and the suction surface which is a slit of 2 mm in length and 80 mm in width is provided on the side surface 16C having the smaller area. 17 is formed.

  Moreover, as shown in FIG. 2, the suction nozzle 16 includes a rectangular upper surface 16E and a lower surface 16F that face each other above and below the side surfaces 16A to 16D. The upper surface 16E is inclined with respect to the lower surface 16F, and the inside of the suction nozzle 16 expands from the suction port 17 toward the back. Further, the upper surface 16E and the lower surface 16F are flat, and the area is significantly wider than the side surfaces 16A to 16D. Therefore, the sheet material 18 and the corrugated board D are arranged from the other end in the longitudinal direction of the corrugated board D (hereinafter referred to as the non-fixed side) with the suction nozzle 16 facing the lower surface 16F downward, the upper face 16E facing upward and the suction port 17 facing sideways. Are inserted between the lower surface 16F and the upper surface 16E are in close contact with the cardboard D. Further, a gap is formed between the cardboard D and the sheet material 18 in front of the suction port 17.

  When the suction device 12 is operated in this state, the sheet material 18 is brought into close contact with the upper surface 16E of the suction nozzle 16 and the cardboard D by the suction force from the suction port 17 in front of the suction port 17. And the sealing performance between the suction nozzles 16 becomes high. Thus, an air flow path directed only to the suction port 17 is formed in front of the suction port 17. For this reason, since the suction force of the suction device 12 acts on the cardboard D without losing it, the toner adhering to the cardboard D can be sucked up vigorously.

  Then, as shown in FIG. 1, the suction device 12 is operated while moving the suction nozzle 16 from the non-fixed side to the fixed side of the cardboard D (in the direction of arrow A in the figure), so that the direction of travel of the suction nozzle 16 ( The cardboard D is cleaned along the direction of arrow A in the figure. Further, the suction nozzle 16 is shifted in the short direction of the cardboard D (in the direction of arrow B in the figure), and the suction device 12 is operated while moving again from the non-fixed side to the fixed side of the cardboard D. The surface where the toner is cleaned spreads in the direction of arrow B in the figure.

  In this manner, the upper surface 16E of the suction nozzle 16 is brought into close contact with the sheet material 18 and the lower surface 16F is brought into close contact with the cardboard D, and the suction nozzle 16 is inserted between the cardboard D and the sheet material 18 with the suction port 17 facing sideways. Therefore, a wide range of toner on the cardboard D can be sucked at once. Therefore, the cleaning time can be shortened.

  In addition, since the toner adhering to the cardboard D can be sucked into the suction device 12 without being scattered, it is not necessary to clean up the toner after cleaning the cardboard D. Therefore, the number of work steps can be reduced and the equipment cost can be reduced.

  In addition, since the suction port 17 of the suction nozzle 16 is a slit extending along the cardboard D, the suction nozzle 16 can be thinned, and the gap between the sheet material 18 and the cardboard D can be narrowed. For this reason, the suction force of the suction device 12 acting between the sheet material 18 and the cardboard D is increased, and the speed of sucking the toner is increased. Therefore, the cleaning time can be shortened.

  In the present embodiment, the ratio A: B between the length A in the longitudinal direction and the length B in the short direction of the suction port 17 of the suction nozzle 16 is 40: 1 (A = 80 mm, B = 2 mm). If the thickness is too large with respect to the width of the suction nozzle 16, the sealing performance between the sheet material 18 and the corrugated board D and the suction nozzle 16 is lowered, so A: B is 20: 1 to 150: 1. It is desirable to be satisfied.

  In this embodiment, since A: B satisfies the above conditions, the sealing performance between the sheet material 18 and the cardboard D and the suction nozzle 16 can be sufficiently increased. It is possible to increase the air flow rate between the two. Accordingly, the toner adhering to the cardboard D can be suctioned vigorously, and the cleaning time can be shortened.

  In the present embodiment, the thickness of the sheet material 18 is 0.25 mm. Here, when the sheet material 18 is too thin, the sheet material 18 is sucked into the suction port 17 and the suction port 17 is blocked by the sheet material 18, so that the toner attached to the cardboard D can be sucked. In addition, if the sheet material 18 is too thick, no suction force acts on the sheet material 18 and the sheet material 18 is not in close contact with the cardboard D, so that the suction force from the suction nozzle 16 is weakened. For this reason, it is desirable for the thickness of the sheet material 18 to be an appropriate thickness of 0.2 to 2.0 mm. In the present embodiment, since the thickness of the sheet material 18 satisfies the above condition, it is possible to absorb the toner satisfactorily.

  In the present embodiment, the material of the sheet material 18 is urethane. It has been confirmed that urethane has an appropriate strength and is not sucked into the suction port 17 of the suction nozzle 16 to block the suction port. However, as long as the material of the sheet material 18 has the same strength as urethane, other materials such as vinyl chloride may be used.

  Further, in the present embodiment, the present invention has been described by taking the cleaning device 10 that sucks toner adhering to the cardboard D as an example. However, the present invention is not limited to this, and the present invention is used when dust adhering to a flat surface or curved surface is sucked. Is applicable. Note that when dust adhering to a curved surface is sucked, the lower surface of the suction nozzle can be curved to seal the surface to be cleaned, the sheet material, and the suction nozzle.

  Further, in the present embodiment, the shape of the suction nozzle 16 is a trapezoidal columnar shape, but the shape of the suction nozzle 18 may be any shape as long as the lower surface is in contact with the surface to be cleaned and the upper surface is in close contact with the sheet material. A suction port may be formed in a columnar shape on an elliptical side surface. In this case, since the sealing performance between the curved upper surface and the sheet material is increased, the suction force can be further increased than in the present embodiment.

It is a perspective view which shows the cleaning apparatus of this embodiment. It is sectional drawing which shows the cleaning apparatus of this embodiment.
