[Problems to be solved by the invention]
As in Patent Document 1, the following problem has occurred in an apparatus for cleaning by inserting a collection tube from the opening of a container having an open top to the vicinity of the bottom of the inside.
[0005]
The first problem is that it takes a lot of time to clean the entire interior of the container. That is, in Patent Document 1, a collection tube is inserted to the bottom of a carton container, and a dust collecting hood that spreads paper dust, polyethylene dust, etc. scattered by the injection of high-pressure air to the inside diameter of the container is drawn. A structure that sucks up from the mouth is adopted. For this reason, high-pressure air does not reach above the hood, and a sufficient scattering effect cannot be expected. Therefore, in order to clean the entire inside of the container completely, it is necessary to move the recovery pipe up and down inside the container. Therefore, it takes a lot of time to sufficiently clean one carton container.
[0006]
The second problem is that the size of the container to be cleaned is extremely limited. In Patent Document 1, an air injection nozzle for injecting high-pressure air and a powder recovery hood are provided in the recovery pipe. In particular, as described above, the opening of the hood for collecting powder is expanded to the vicinity of the inner diameter of the container so that paper dust, polyethylene dust, and the like scattered by jetting high-pressure air can be collected effectively. However, if the diameter of the opening of the hood is extremely smaller than the inner diameter of the container, not only the dust collection effect by the hood will be drastically reduced, but also paper dust, polyethylene dust, etc. scattered by high-pressure air may There is also a risk of splashing outside and contaminating another container that has already been cleaned. That is, the container can be effectively cleaned only when the diameter of the hood opening approximates the inner diameter of the container.
[0007]
In addition, if high-pressure air is jetted at a position away from the bottom of the container, the opening of the hood for collecting the powder is also separated from the bottom, and there is a possibility that the scattered paper powder, polyethylene dust and the like cannot be collected effectively. As a result, the containers that can be cleaned are limited to containers that are at least sized so that the collection tube can be inserted to the bottom. Therefore, in the removal apparatus described in Patent Document 1, as described above, the diameter of the opening of the hood is close to the inner diameter of the container, and only the container having a size in which the recovery tube can be inserted to the vicinity of the bottom. Can be used. Other containers cannot be used at all, or even if they can be used, a sufficient cleaning effect cannot be expected, and the size of the container to be cleaned is extremely limited.
[0008]
As described above, the conventional removal apparatus has various problems such as a long cleaning time and a very limited size of the container that can be cleaned. Therefore, the present invention was created to solve the above-described problems, and an object of the present invention is to provide a container cleaning device that can be sufficiently cleaned in a short time and that can be widely applied to the size of containers. Is.
