Description

The present invention relates to an apparatus suitable for polishing long materials such as long-sized flat plates, square members, strips, and other irregularly shaped materials having obtuse angles by projecting abrasive grains while moving.

Conventionally, long materials are generally cleaned by passing a long material through a cabinet that is equipped with an abrasive grain projection device and constitutes a polishing chamber.

  However, in the conventional scouring device configured as described above, it is necessary to carry out scouring by taking a long material into the factory where the scouring device is installed. When a large number of adhering long materials and the like are cleaned, there are problems such as lack of convenience.

The problem to be solved is one of the components that make up the equipment, but when a large number of long materials, etc., to which harmful substances have adhered are to be cleaned, the conventional polishing equipment lacks convenience. is there.

  In order to solve the above problems, the movable long material blasting device in the present invention is a device for projecting abrasive grains while moving and scouring the long material, wherein the long material is horizontal. A surrounding chamber that can penetrate the hollow chamber and that is movable in the horizontal direction, and projects abrasive grains obliquely upward toward the long material that is attached to the lower portion of the surrounding device and penetrates the hollow chamber One centrifugal abrasive grain projecting device having an impeller, a reflecting member mounted on the upper inner surface of the surrounding means and reflecting downwardly projected abrasive grains from the centrifugal abrasive grain projecting device, and the enclosure Abrasive feeding means for feeding abrasive grains in the lower part of the means to the centrifugal abrasive grain projection device.

In the structure configured as described above, after the long material is inserted into the surrounding means, the entire polishing apparatus is moved along the long material while projecting abrasive grains from the centrifugal abrasive grain projecting device. Thereby, a long material can be cleaned.

As is apparent from the above description, the present invention comprises a surrounding chamber in which a long material can be horizontally penetrated and movable in the horizontal direction, and the hollow chamber mounted on the lower portion of the surrounding means. One centrifugal abrasive grain projection device having an impeller for projecting abrasive grains obliquely upward toward the long material penetrating, and a projection from the centrifugal abrasive grain projection device mounted on the upper inner surface of the surrounding means A reflecting member that reflects the abrasive grains downward and an abrasive feeding means that feeds the abrasive grains in the lower part of the enclosing means to the centrifugal abrasive projection device. After inserting the material, the long material can be properly cleaned by simply moving the entire polishing device along the long material while projecting abrasive grains from the centrifugal abrasive grain projection device. Excellent practical effect.

Hereinafter, the best mode of the mobile long material polishing apparatus to which the present invention is applied will be described in detail with reference to FIG. 1 &#12316; FIG. This mobile long-abrasive device for long materials constitutes a hollow chamber that can be penetrated in a state in which a flat surface of a rectangular plate W as a long material extends in the horizontal direction, and can be moved in the horizontal direction. Means 1 and an impeller for projecting abrasive grains obliquely upward toward the plate member W that is attached to the lower part of the surrounding means 1 and penetrates the hollow chamber, and a group of abrasive grains that are projected and spread in a fan shape One centrifugal abrasive grain projection device 2 substantially orthogonal to W, and a reflection that is attached to the upper inner surface of the surrounding means 1 and reflects the abrasive grains projected from the centrifugal abrasive grain projection device 2 downward. A member 3 and a screw conveyor 4 as abrasive grain feeding means for feeding abrasive grains in the lower part of the surrounding means 1 to the centrifugal abrasive grain projection device 2 are configured.

The surrounding means 1 forms a lower narrow space and, as shown in FIG. 2, a plurality of rollers 5 and 5 are axially attached to the upper left and right outer surfaces with appropriate intervals in the front-rear direction. The hopper 6 and a hood 7 having an arched longitudinal section that forms a space so as to surround the upper end opening of the hopper 6 are configured, and the plurality of rollers 5 and 5 support a plate material. Mounted on the upper surface of the support means 20 so as to be horizontally movable, the surrounding means 1 can move in the left-right direction on the upper surface of the support means 20 via the plurality of rollers 5 and 5 in FIG. It is like that. In addition, the reflective member 3 is mounted in the vicinity of the center of the lower surface of the ceiling portion of the hood 7. Further, the ceiling portion of the hood 7 has a number of rubber warmers 8 and 8 for preventing abrasive grains from jumping out. It is suspended in the left-right direction at an appropriate interval. Further, as shown in FIG. 1, a suction port (not shown) communicating with a dust collector (not shown) is provided on the left side of the hopper 6, and further, scattered abrasive grains are collected on the right side of the hopper 6. A receiving hopper 9 is provided.

Further, as shown in FIG. 3, the centrifugal abrasive grain projection device 2 includes an impeller 9, a case 10 surrounding the impeller 9, a distributor 11 for dispersing abrasive grains in the impeller 9, an impeller 9, and The motor 12 is configured to rotate the distributor 11.

Further, the screw conveyor 4 is attached to the cover 13 with a hook-like cover 13 with a left end closed attached to the lower end opening of the hopper 6, a screw shaft 14 rotatably disposed in the cover 13, and a cover 13. It is composed of a shielding member 17 that forms an abrasive grain entrance 15 and an exit 16 and a motor 18 that rotates the screw shaft 14, and abrasive grains that have entered the cover 13 through the entrance 15 The screw shaft 14 can be rotated toward the center of the distributor 11 of the centrifugal abrasive grain projection device 2 by the rotation of the screw shaft 14.

In this configuration, the screw shaft 14 is rotated by driving the motor 18 of the screw conveyor 4 to feed the abrasive grains in the hopper 6 through the cover 13 into the distributor 11 of the centrifugal abrasive grain projection device 2. At the same time, the impeller 9 and the like are rotated by driving the motor of the centrifugal abrasive grain projection device 2 to project the abrasive grains in the direction of the reflecting member 3, and the plate material W is inserted into the hood 7, and then the support means 20 is interposed. The entire polishing apparatus is moved to the left along the plate material W. Thereby, the lower surface of the board | plate material W can be cleaned.

It is a front view which shows the best form of this invention. It is a right view of FIG. FIG. 2 is an enlarged detail view of part A in FIG. 1.
