Abstract

PROBLEM TO BE SOLVED: To make it possible to efficiently execute a scraping treatment to remove the deposits of small articles with lessened manpower. SOLUTION: A drum 3 formed to a bell shape is arranged to be made freely rotatably in an inclined state in such a manner that a feed and discharge port 8 faces diagonally upward. The inner peripheral surface of the drum 3 is provided with vanes 57 for scraping up the small articles. The drum 3 is partly immersed into a water collecting tank 5. The deposits on the many small articles are efficiently removed with the lessened manpower by the collision of the small particles against each other by raking up and dropping thereof and the swelling of the deposits by water.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to various small parts,
For example, the present invention relates to a cleaning device for removing deposits on metal parts such as steel pipe clamps which are building materials.

[0002]

2. Description of the Related Art At a construction site, a steel pipe clamp used for assembling a scaffold or the like causes adhesion of concrete, paint, and the like. Therefore, it is necessary to remove the attached matter for reuse after collection. is there.

[0003] Conventionally, a worker removes deposits on a steel pipe clamp by hand manually one by one.

[0004]

However, the manual operation of keren has a problem that the work efficiency is extremely poor, the processing cost is high, and the work is heavy labor.

Accordingly, the present invention provides a small part cleaning device capable of simultaneously and automatically performing the cleaning of a large number of small parts, thereby reducing the labor required for the cleaning work, improving the efficiency and reducing the processing cost. That is the task.

[0006]

In order to solve the above problems, according to the invention of claim 1, the tip opening of the bell-shaped drum serves as a supply / discharge port for small parts, and the drum is supplied / discharged. The shaft is tilted so that the outlet is obliquely upward, and it is rotatably arranged. Inside the drum, small parts are removed when the drum rotates in the keren direction, and small parts are directed to the supply / discharge port during reverse rotation. It adopts a configuration in which blades are provided for feeding.

According to a second aspect of the invention, in the first aspect of the invention, a structure is provided in which a water collecting tank for submerging the lower portion of the drum is provided immediately below the drum.

[0008] Here, when small parts are put into the drum from the supply / discharge port and the drum is rotated in the keren direction, the small parts are repeatedly lifted up and dropped by the blades, so that the small parts collide with each other. Adhesives are automatically peeled and removed, and small parts can be discharged by reversing the drum.If water is attached to the small parts with the water in the water collection tank, the small parts can be exfoliated by swelling due to water. When the blades are repeatedly picked up and dropped, the small particles collide with each other, and the deposits are automatically separated and removed.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the drum 3 placed on the water collecting tank 5 is formed in a bell shape by connecting a truncated cone-shaped cylinder 52 to the rear end of the cylindrical cylinder 51, and the tip opening of the cylindrical cylinder 51 supplies small parts. A shaft 53 fixed to the center of the rear end face of the truncated cone body 52 is rotatably supported by a bearing of a support base 54, and a lower portion of the cylindrical body 51 is supported by a pair of receiving rollers 55. The axis is inclined so that the outlet 8 faces obliquely upward.

In the drum 3, the frustoconical cylinder 52 and the cylindrical cylinder 51 are formed of a porous plate, and the lower portion of the drum 3 is soaked in the water in the water collecting tank 5 as shown in FIG. Forward / reverse rotation is applied by the motor 13.

On the inner peripheral surface of the drum 3, screw blades 56 are fixed near the feed / discharge port 8 of the cylindrical body 51. Further, a large number of screw blades 56 are provided from the middle of the cylindrical body 51 to the inner end of the truncated cone body 52. The blades 57 are fixed at an angle in the circumferential direction.

The screw blades 56 smoothly feed and discharge small parts into and out of the drum 3 by the forward and reverse rotations of the drum 3, and a large number of blades 57 raise the small parts and feed them in the axial direction. Play a role.

On the upper outside of the supply / discharge port 8 of the drum 3, a small component supply conveyor 38 and the conveyor 3 are provided.
A chute 39 for guiding the small parts discharged from the drum 8 into the drum 3 is arranged, and a chute 41 for accommodating the small parts discharged from the drum 3 in a container is further provided at a position on the lower outside of the supply / discharge port 8. Are arranged.

The keren device of the present invention has the above-mentioned structure. When the drum 38, into which small parts are introduced by the conveyor 38 and the chute 39, is rotated in the forward direction by the motor 13, the small parts are screw blades 56 and a large number of small parts. The blade 57 moves to the inside of the drum 3, and the blade 57 repeats raising and dropping.

Since the lower part of the drum 3 rotates while being immersed in the water in the water collecting tank 5, the deposits of small parts swell due to the deposit of water, and are effectively peeled and removed.

When the drum 3 is reversed after the cleaning, the small parts are sent to the supply / discharge port 8 by the blades 57 and the screw blades 56, and taken out to the outside by the chute 41.

[0018]

As described above, according to the present invention, the blades provided on the inner periphery of the drum cause mutual collision of the small parts, and the water supply means by the water collecting tank gives water to the small parts. Therefore, it is possible to automatically and efficiently perform a large number of cleaning operations to remove the deposits on small parts at the same time. Also, by swelling the deposits with water and improving the peelability, it is possible to clean the small parts. Processing efficiency can be improved and labor can be saved, and processing costs can be reduced.

Further, by forming the drum in a bell shape, it is possible to easily arrange the drum in a partially flooded state with respect to the water in the water collecting tank by the inclination.
