Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for washing off dirt adhering to a cylindrical container or a conical container.

[0002]

2. Description of the Related Art In a printing factory, when dyeing a cloth, a dye and a sizing agent are put in a container and agitated. The stain adhered to the container must be washed off. However, the adhering substance obtained by mixing the above-mentioned dye and sizing agent is difficult to wash off, and it takes too much time for the worker to manually perform the work, resulting in heavy labor. That is, in a printing factory, a large number of containers are used, and not one or two containers. And when a worker manually cleans, it is not only time-consuming and hard labor as described above, but also because the worker himself is contaminated with these dyes and pastes, even in a work field that is often avoided. is there. In addition, the unwashed residue also occurs.

[0003]

As described above, when cleaning a large number of containers, there are the above problems. The problem to be solved by the present invention is this problem, and provides a container cleaning device capable of automatically washing off the dirt attached to the inner surface and the outer surface of the container.

[0004]

The container cleaning apparatus of the present invention is an apparatus in which a conveyor and a cleaning machine are combined, and the container conveyed by the conveyor is cleaned by the cleaning machine, and the cleaned container is carried out. It is configured to be done. The conveyor may be a belt conveyor or a chain conveyor, but the container is carried by being locked by a claw attached to the belt or the chain. In this case, the container is conveyed upside down and washed in the upside down state.

Then, the washing machine clamps and positions the container, and at the same time, sprays the washing liquid while rotating. Dirt mixed with dye and paste has a strong adhesive force and is washed off with a cleaning liquid that is sprayed at high speed from a nozzle. Therefore, a plurality of arms having a roller at the tip and swinging are provided, and by rotating the rollers, the container is brought into contact with the container, and the container is positioned and rotated. Even if the size of the container changes, the roller is correctly positioned in the center of the washing machine. Further, the nozzle for ejecting the cleaning liquid is attached to a curved pipe, and the pipe is controlled so that the cleaning liquid is spread to every corner of the container which swings and rotates. The curved pipes are provided inside and outside the container, respectively, and a stationary nozzle may be provided at a predetermined position.

The swing angle of the curved pipe is determined by the size of the container, and therefore the size is detected by a sensor before entering the washing machine. Here, the number of curved pipes and the number of injection nozzles are not limited. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 (a) and 1 (b) are embodiments showing the outline of a container cleaning apparatus of the present invention. In FIG. 1, 1 is a cleaning machine, 2 is a supply conveyor, and 3 is a discharge table. ing. And (a) shows the case where the washing machine 1 is arranged between the supply conveyor 2 and the discharge table 3 and arranged linearly, (b)
Is a device that can arrange three washing machines 1, 1, ... In parallel and supply the containers 4, 4, ... To each washing machine 1, 1 ,. Therefore, the containers 4, 4, ... Which have been conveyed by the supply conveyor 2 enter the cleaning machine 1 to be cleaned,
It is discharged to the discharge table 3.

FIG. 2 shows the case where the containers 4, 4 ... Are conveyed by the supply conveyor 2, the conveyor chain 5 is wound around the sprockets 6, 6 and runs, and the claws are placed at various places on the conveyor chain 5. 7, 7, ... Are attached. The containers 4, 4, ... Mounted on the supply conveyor 2a are pushed by the tabs 7, 7 ,. This supply conveyor 2a
Is connected to another supply conveyor 2b provided below the washing machine 1.

FIG. 3 is a sectional view of the supply conveyor 2. A guide rail 8 is provided between the sprockets 6 and 6 to support the conveyor chain 5 so as not to bend. A connecting member 9 is hung between the conveyor chains 5 and 5, and the pawl 7 is attached to the connecting member 9. The supporting frame is located above the conveyor chain 5 and at a position lower than the protruding claw 7 and the supporting pieces 10, 10
Is provided, and the container 4 is carried while sliding on the support pieces 10 and 10.

FIG. 4 shows an injection nozzle 1 provided in the washing machine 1.
.., 11 ... Curved pipes 12a and 12b are mounted above the container 4 so as to be swingable about shafts 13a and 13b, and a curved pipe 14 is mounted inside the container 4 so that they can be swung around a shaft 15. ing. The swing angles of these curved pipes 12a, 12b, 14 are adjusted according to the size of the container 4 to be washed, but the pistons of the air cylinders 16a, 16b, 17 connected to the arms extending from the shafts 13a, 13b15. It is connected to the rod.

By the way, while the container 4 is rotating, water sprayed from the spraying nozzles 11, 11 ... Provided on each of the curved pipes 12a, 12b, 14 or high pressure hot water is used to wash dirt on the surface. Be dropped. in this case,
The distance between the injection nozzle 11 and the container surface and the rotation speed of the container are important for enhancing the cleaning effect, and the cleaning effect does not increase even if the distance between them is too great or the rotation speed is too high. Generally, the distance is 10 to 20 cm, and the rotation peripheral speed of the container at this time is preferably 20 m / min or less.

Then, the liquid used for cleaning flows down and passes through the filter. At this time, solid substances which are difficult to pass through the nozzle are removed and temporarily stored in the lower tank. Then, this liquid is pumped up and used again for cleaning. However, as the number of circulations used increases, the polluted concentration of the liquid becomes remarkable, which causes trouble in cleaning. For this reason, fresh water is constantly replenished in the tank to prevent pollution, while part of the used old liquid is discharged from the overflow hole of the tank. Also, as the final washing after washing, the liquid in the tank is not used, only fresh water is pumped up and spouted from the nozzle, and the old liquid in the entire tank is rinsed out, thereby suppressing the increase in the pollutant concentration of the liquid in the tank. I can.

By the way, the container 4 that has entered the washing machine is located at the center and rotates at a constant speed. While rotating, the washing liquid is ejected from the jet nozzle to wash off the dirt adhering to the surface. Therefore, the washing machine 1 is equipped with a device for positioning and rotating the container. 5, 6, and 7
Is a concrete example showing this device.
