BACKGROUND OF THE INVENTION
The present invention relates to a box used when an empty tube container before filling contents is stored in a box body and transported from a tube container manufacturing factory to a contents filling factory.
[0002]
[Prior art]
In general, in a tube container filled with contents such as creamy medicines and cosmetics, a cap is screwed into the mouth until the contents are filled, and at the end of the body of the tube container. there skirt is packed in Kayoibako while being opened. Most of the boxes are made of synthetic resin boxes, and empty tube containers are packed in a tube container manufacturing factory, loaded on a truck or the like, and transported to a content filling factory. In the content filling factory, the tube container in the pass box is supplied to the filling machine, and the empty tube container is filled with the content. As such a conventional box, there is one as shown in FIG. In FIG. 8, a plurality of empty tube containers 104 are stored in the box body 101. After the storage, the lid of the box body 101 is covered with the lid, and the opening of the box body 101 is securely closed. Then, the passing box 100 transported to the content filling factory is flowed on the conveyor, and after the lid is removed, an empty tube container is manually pulled out from the box body 101, and then on the conveyor of the content filling machine. I was doing work to transfer to. However, manual transfer work has poor work efficiency, and the idea of transferring it with the industrial robot 102 has emerged. That is, a plurality of holders 103 attached to the tip of the hand of the industrial robot 102 are inserted into the opening at the bottom of the tube container 104, and the tube container 104 of 10 to 20 units is This is extracted from the box body 101. The pass box 100 from which all the tube containers 104 have been extracted is returned again to the tube container manufacturing factory in order to pack the tube containers 104. And the pass box 100 is used repeatedly.
[0003]
In addition to the above-described box, a box with a supply hole having a supply hole in the box body is used. That is, when a tube container with a supply hole is used to pack a tube container into a box at a tube container manufacturing factory, the supply hole of the box body is closed by a contact plate, and the tube container is a content filling factory. When the abutment plate is removed from the box body, the tube container is fluidly supplied directly from the supply hole of the box body to the filling machine. It is what is done.
[0004]
[Problems to be solved by the invention]
However, such an invention has the following drawbacks. As shown in FIG. 8, a gradient θ of about 0.5 to 2 ° is provided between the bottom surface 105 and the side surface 106 of the box 100. The reason why the gradient θ is provided is that the pass box 100 is usually formed by pouring molten resin into a mold, but the box body 101 of the pass box 100 can be easily removed from the mold after molding. It is to do. That is, in order to facilitate extraction, the gradient θ is provided so as to spread from the bottom surface 105 side of the box body 101 toward the opening side. When a plurality of holders 103 of the industrial robot 102 are inserted into the skirt of the tube container 104 stored in the box body 10 having such a gradient θ, the tube container 104 is not stored vertically. Since the hand holder 103 cannot be inserted into the opening at the bottom of the tube container 104, it cannot be removed by the industrial robot 102, and the tube container 104 is used as a content filling machine. There was a drawback that it could not be transferred. Similarly, in the box with a supply hole, since a gradient θ of about 0.5 to 2 ° is provided between the bottom surface and the side surface of the box, it is directly connected to the filling machine at the content filling factory. When the tube container is set and supplied, the tube container is inclined in the box body, so that the tube container is not smoothly supplied from the supply hole to the filling machine.
[0005]
The present invention has been made paying attention to such a conventional problem, and requires a smooth and efficient extraction operation using an industrial robot and quick transfer to a content filling machine without the need for human resources. An object of the present invention is to provide a through box which can be operated and can smoothly supply a tube container to a filling machine.

In the middle of the flow of the conveyor 41, the tube container 6 is transferred onto the conveyor 42 of the content filling machine 40 by the plurality of tube holding jigs 9 at the tip of the hand 8 of the industrial robot 7. That is, as shown in FIG. 3, a holding jig 9 is inserted from the opening of the tube container 6, and the tube container 6 is sandwiched by expanding the holding jig 9 to the outside, and 10 to 20 pieces at a time from the box body 1. The empty tube container 6 is extracted. The industrial robot 7 rotates the direction of the hand 8 in the direction of the conveyor 42 to transfer the tube container 6. In this way, the tube container 6 can be easily transferred from the passing box 1 to the tube holder 43 on the conveyor 42 of the content filling machine 40. The tube container 6 transferred to the tube holder 43 is supplied to the content filling machine 40, and the tube container 6 is filled with the content. Then, the empty box 1 is returned again to the tube container manufacturing factory in order to pack the tube container 6.
[0015]
FIG. 6 is a perspective view showing a second embodiment when the vacuum molded body 10 is applied to a conventional box with a supply hole. The box with supply holes is a contact plate 38, the supply holes 37 of the box body 31 are closed, and the tube container 36 is transported from the tube container manufacturing factory to the content filling factory. Then, as shown in FIG. 7, in the content filling factory, after setting directly on the box mounting base 40 a of the filling machine 40, the contact plate 38 is removed from the box body 31, thereby directly connecting the tube container 36. Is fluidly supplied from the supply hole 37 to the filling machine 40. In the second embodiment which is such a box with a supply hole, since the box body 31 has the extraction gradient θ as in the first embodiment, the box body 31 is attached to the box of the filling machine 40. When set on the table 40 a, the tube container 36 is inclined and flows out from the supply hole 37 because the bottom side of the tube container 36 is lowered and inclined. Therefore, similarly to the first embodiment, by providing the vacuum formed body 34 in the box body 31, the tube container 36 is held horizontally in the box body 31 as shown in FIG. Therefore, the tube container 36 flows out horizontally from the supply hole 37 to the filling machine, and the supply flow of the tube container 36 to the filling machine can be smoothed.
