  Packing packing materials such as air cushions, foam sheets, foam cushions, etc. in packaging containers such as cardboard boxes in order to prevent breakage in the process of shipping packaging made of glass or resin. Is generally done. However, static electricity is easily generated on the surface of the packaging material described above due to friction or the like. When static electricity is generated, dust adheres to the packaging material. The dust adhering to the packaging material in this way easily adheres to a packaging container made of glass or the like that is an object to be packed.

  The present invention provides a dust removing device having a static eliminator for avoiding such inconveniences, more specifically, providing a dust removing device capable of removing dust on both the front and back surfaces of the packing material at the same time, and further, packing material to be dust removed. It is an object of the present invention to provide a dust removal device for packing materials that can continuously convey and remove packing materials of different thicknesses and forms continuously, regardless of the thickness of the packaging materials.

  In order to solve the above problem, the dust removing apparatus according to claim 1 uses a rope conveyor as a conveying means for conveying the packing material, and ionized air blowing for blowing ionized air generating means and ionized air onto the surface of the packing material. The static eliminator provided with the means was arranged on the upper and lower surfaces of the transport path in the rope conveyor. Further, the dust removing apparatus according to claim 2 is configured such that the ionized air is blown on the upper surface and the lower surface of the packaging material simultaneously and substantially perpendicularly to the packaging material.

  Further, in the dust removing device according to the third aspect, a suction fan is disposed on the lower surface of the transport path. According to a fourth aspect of the present invention, there is provided a dust removing apparatus according to any one of the first to third aspects, wherein a plurality of rod-shaped pressing members are provided on a rope conveyor in the vicinity of the static eliminator placement position.

  The following describes how the present invention configured as described above solves the problems with reference to the drawings.

The dust removal process of the dust removal apparatus according to the present invention will be described with reference to FIG. The packing material to be dust-removed is placed on the rope conveyor 20 at the lower left in FIG. 1 and conveyed toward the upper right in the drawing. At this time, ionized air is blown from the static eliminator 10 disposed on the upper surface of the rope conveyor 20 as the transport path and the static eliminator 11 disposed on the lower surface, so that the charges are removed by the ions and the attached dust is compressed. It is removed from the surface of the packaging material by air.

  As described above, according to the present invention, since the static eliminators 10 and 11 are disposed on the upper and lower surfaces of the rope conveyor 20 and the rope conveyor is used, not only the upper surface of the packing material is used for ionizing air. It is possible to spray on the lower surface. That is, it is possible to remove dust on the front and back surfaces of the packing material in one step. In other words, it is not necessary to perform dust removal in two steps, such as turning the packing material upside down after the dust is removed in the first step and removing the opposite surface in the next step. .

  Further, in the dust removing apparatus according to the second aspect, the ionized air is blown on the upper and lower surfaces of the packaging material at the same time and substantially perpendicularly to the packaging material. At the same time, since it is blown almost vertically on the upper and lower surfaces, it is possible to eliminate as much as possible the problem that the packing material to be removed is blown away by compressed air, and it is possible to efficiently remove dust on both sides of the packing material efficiently. It becomes.

  In the dust removing device according to the third aspect, as shown in FIG. 2, a plurality of suction fans 30 are arranged on the lower surface of the transport path. The suction fan 30... Has a structure that sucks air in the vicinity of the conveyance path downward through a filter 31. That is, it acts to bring the packing material into close contact with the rope conveyor 20 and can more efficiently prevent the packing material as a dust removal target from being blown off by ionized air.

  In the dust removing apparatus according to the fourth aspect, a plurality of bar-shaped pressing members 40 are provided on the rope conveyor 20 near the positions where the static eliminators 10 and 11 are disposed. The pressing member 40 acts to press the packing material against the rope conveyor 20. Thereby, the disadvantage that the packing material is blown away by the ionized air can be avoided.

  As described above, according to the present invention, it is possible to prevent as much as possible packing materials, which are usually light in weight, from being scattered by ionized air, and to set the ionizing air blowing strength and installation position of the static eliminator. There is no need to adjust according to the thickness and form of the packing material to be removed. In other words, it becomes possible to sequentially and continuously remove packing materials having different thicknesses and forms.
