It is installed so that it can be moved up and down.

  As shown in FIGS. 1, 2, and 3, the dust removing mechanism 40 has a cylindrical shape that can enter the body 11 of the 18 liter can 10 while keeping a predetermined gap from the inner surface of the body. Suction cylinder 41 and a disc-shaped rotating disk 42 disposed above the suction cylinder 41. The turntable 42 has a diameter that does not protrude outside the suction drum 41.

  The suction cylinder 41 is closed at the upper end by a closing plate 43. Further, the lower part is connected to an exhaust cylinder 44 that is thinner than the suction cylinder 41 at a substantially right angle, and an exhaust pipe (not shown) is connected to the outer end of the exhaust cylinder 44, and a dust collector (not shown) is connected via the exhaust pipe. Can be connected with.

  A suction port 45 is formed in each upper side wall of the suction drum 41 so that each suction port 45 faces the inner surface of the barrel portion 11 of the 18 liter can 10.

  The turntable 42 is connected to and supported by the upper end of a rotation support rod 46 that is rotatably installed along the central axis of the suction drum 41.

  An air supply pipe 47 is introduced into the rotation support rod 46. As shown in FIG. 3, a cross-shaped rib 48 is provided on the upper surface of the turntable 42. The tips of the ribs 48 substantially coincide with the outer periphery of the rotating disk 42.

  In the can cleaning apparatus according to the present invention, an air outlet is provided on the distal end side of the suction drum 41 on the side where the dust removing mechanism 40 is inserted into the 18 liter can 10 through the opening 14 of the 18 liter can 10. However, in the illustrated embodiment, air jets 49 and 50 are opened on the tip surface and one side surface of the rib 48, respectively. In the illustrated embodiment, one air jet 49 is opened at the tip surface of the rib 48, and a plurality (three in the figure) of air jets 50 are opened on one side of the rib 48. The positions at which the air jets are arranged on the upper end side of the suction drum 41 and the number thereof are not limited to the illustrated form, but when the suction drum 41 moves up and down in the 18 liter can 10 as will be described later, As shown in FIGS. 1 to 3, the air outlet and the inlet 45 are arranged close to each other so that the inlet 45 and the inlet 45 are integrally moved up and down in the 18 liter can 10. It is desirable.

  The air outlets 49 and 50 are communicated with an air supply pipe 47 through an air passage (not shown in the figure) provided in the rib 48, and the compressed air supplied through the air supply pipe 47 receives each air. It can eject from the ejection ports 49 and 50. The compressed air is supplied through a supply pipe (not shown) connected to the air supply port 51 of the air supply pipe 47.

  In the illustrated embodiment, the air outlet 50 formed on one side surface of the rib 48 provided on the upper surface of the turntable 42 is formed so as to be inclined so that the air to be jetted is directed obliquely upward. Further, the air outlet 49 formed on the front end surface of the rib 48 is formed in the longitudinal direction of the rib 48 so that the air to be ejected is directed in the longitudinal direction of the rib 48.

  The dust removing mechanism 40 configured in this way is moved up and down (not shown) (the dust removing mechanism 40 is moved from the outside of the main plate 12 by the can holding means 20 toward the 18 liter can 10 to move the inside of the 18 liter can 10. 1) through the opening 14), and moves up and down as indicated by arrows 1 and 2 in FIG. 1, and enters and retracts into the 18 liter can 10 held below the can holding means 20. It has been made possible.

  Further, a rotation driving mechanism (not shown) is connected to the rotation support rod 46 installed along the central axis of the suction drum 41, and the rotary disk 42 is moved as shown by the arrow 3 in FIG. It can be rotated in the direction.

  The can cleaning device of the illustrated embodiment further includes an air ejection nozzle 52 having a tip opening facing a joint 15 formed by welding or the like along one corner of the body 11 of the 18 liter can 10. Is provided.

  The air ejection nozzle 52 is fixedly provided on the suction drum 41 that constitutes the dust removing mechanism 40. The upper end of the suction cylinder 41 extends obliquely downward from one corner of the closing plate 43 so that the front end opening faces the joint 15 of the 18 liter can 10. Although the figure shows the case where there is one air ejection nozzle 52, a plurality of air ejection nozzles 52 may be provided in the longitudinal direction in which the joint 15 extends.

  An air supply pipe (not shown) introduced through the suction cylinder 41 is connected to the air ejection nozzle 52 provided in the suction cylinder 41, and compressed air is supplied to the air ejection nozzle 52 through the air supply pipe. Compressed air can be ejected to the inner surface of the joint 15 of the 18 liter can 10.

  The inside of the 18-liter can 10 can be cleaned as follows by the can cleaning device configured as described above.

  The 18-liter can 10 with the base plate 12 wound around the body portion 11 is positioned and held by the can holding means 20 with the opening 14 being the portion to be tightened as shown in FIG. Next, the dust removing mechanism 40 is moved up as indicated by the arrow 1 to enter the 18 liter can 10. In this case, for example, the rotating plate 42 of the dust removing mechanism 40 is raised until it is sufficiently close to the inner surface of the main plate 12.

  When the dust removing mechanism 40 is moved up and down in the directions of arrows 1 and 2, the rotating disk 42 is rotated in the direction of arrow 3 and compressed air is supplied from the air jets 49 and 50 formed in the ribs 48 of the rotating disk 42 to the arrow 49a. , 50a. Further, the dust collector connected to the exhaust cylinder 44 is also operated, and the compressed air ejected through the suction port 45 formed in the suction cylinder 41 is sucked as indicated by an arrow 45a.

  After the turntable 42 is sufficiently close to the main plate 12 of the 18 liter can 10 due to the rise of the dust removal mechanism 40, the dust removal mechanism 40 is lowered and retracted out of the 18 liter can 10. When the dust removal mechanism 40 is lowered, the compressed air is continuously ejected from the air ejection ports 49 and 50 and the compressed air is sucked through the suction port 45.

  As described above, when the dust removing mechanism 40 is moved up and down, the compressed air is blown onto the entire inner surface of the main plate 12 and the inner surface of the trunk portion 11 when the compressed air is ejected from the air ejection ports 49 and 50 while rotating the rotating plate 42. . For this reason, the metal powder and other dust adhering to the inner surface of the main plate 12 and / or the inner surface of the trunk portion 11 are removed from the inner surface by the compressed air and float on the flow of the compressed air. The floating dust is sucked into the suction port 45 formed on the side wall of the suction drum 41 and collected.

  The air jets 49 and 50 provided in the rotating disk 42 and the suction port 45 formed in the suction cylinder 41 are relatively close to each other as shown in FIGS. Since the dust is lifted and lowered integrally, the dust that has been blown and removed from the inside of the can by air as described above can be reliably collected without being reattached to the inner surface of the main plate 12 or the trunk portion 11 by scattering. Thus, the dust removal mechanism 40 can be sufficiently cleaned by one elevation, and the efficiency of the cleaning work can be improved.

  For example, a manufacturing process is performed in which a base plate 12 is wound around a body 11 and a container such as oil is charged into an 18-liter can 10 having an opening on the side where the top plate is to be tightened, and the top plate is wound and sealed. In the line, while the 18 liter can 10 is being transported by a transport device such as a conveyor, the cleaning operation is continuously and efficiently performed in the manner described above using the can cleaning device of the present invention. be able to.

  In the case of the cleaning device of the illustrated embodiment in which the air ejection nozzle 52 is provided on the suction drum 41 side, compressed air is also ejected from the air ejection nozzle 52 as indicated by an arrow 52a when the dust removal mechanism 40 is moved up and down. Since the compressed air ejected from the air ejection nozzle 52 is intensively blown to the joint portion 15 of the 18 liter can 10, dust attached to the joint portion 15 can be more reliably separated. Part of the dust separated from the joint 15 can be collected through the suction port 45 and part of the dust can be discharged outside through the opening 14 of the 18 liter can 10.

  Although the compressed air ejected from the air ejection ports 49 and 50 is basically performed by continuous ejection, the compressed air can be intermittently ejected for cleaning by using the air supply means as an intermittent supply means. Similarly, the compressed air to be ejected from the air ejection nozzle 52 with the tip opening facing the joint 15 is basically continuous ejection, but the air supply means may be intermittent ejection with the intermittent supply means. it can.

  Whether the compressed air is ejected continuously or intermittently is determined by the nature of the dust adhering to the inner surface of the 18 liter can 10.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to such embodiments, and various forms are possible within the technical scope grasped from the description of the claims. Can be changed.
