SOLUTION: The continuous adhered powder removing device for moldings having a base plate 1, a conveyor 1 which is fixed onto this bare plate 1 has a net-like belt 3 and transports the moldings and nozzles 6 which are successively connected to means for injecting air and blows the air to the moldings is used, by which the moldings are placed on the net-like belt 3 and are transported and the air is intermittently or continuously blown to the moldings under transportation from above.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for continuously removing powder adhering to a molded article, which can efficiently remove powder adhering to the molded article without touching the molded article without manual operation.

[0002]

2. Description of the Related Art Generally, fragile molded products, such as compression molded products before heat curing in powder metallurgy and injection molded products before heating, are fragile and difficult to handle. When removing, it is common that the removal is manually performed using a brush.

In order to solve this problem, the applicant of the present invention has already disclosed in Japanese Patent Application No. 266256 in 1995 a substrate, an actuator fixed on the substrate, and a molded product in conjunction with the actuator. There has been disclosed an apparatus capable of removing powder adhering to a molded product without a manual operation, comprising an arm and a nozzle provided at a position higher than the arm and connected to a means for injecting air to blow air to the molded product.

[0004]

However, since the apparatus disclosed in the above-mentioned 1995 Patent Application No. 266256 uses an actuator, it is not possible to continuously remove the powder of the molded product. Processing capacity does not increase. Also, in rare cases, when transferring a molded product, the molded product is destroyed when it touches the arm, and there is a problem that productivity is reduced,
Further, there is a problem that it is difficult to remove the powder adhering to the contact portion between the arm and the molded product. It is an object of the present invention to solve these problems, and to provide an apparatus for removing adhered powder of a molded product capable of efficiently removing powder with high processing capability, high productivity, and high efficiency.

[0005]

Means for Solving the Problems The present inventor has conducted studies to solve the above problems and achieve the above object, and as a result,
The present invention has been completed by finding that the object can be achieved by changing the transfer means of the molded product and combining the transfer means with an air blowing means.

That is, the present invention mainly comprises a conveyor for conveying a molded article having a net-like belt fixed on a substrate, and a nozzle for blowing air to the molded article connected to means for jetting air. An apparatus for continuously removing adhered powder from a molded product.

In the present invention, a molded article is conveyed on a mesh belt by operating a molded article conveying conveyor having a mesh belt, and air is intermittently or continuously fed from above the molded article being conveyed. By blowing the powder, the powder adhering to the molded product is blown off and removed.

In the present invention, the air blowing nozzle is
The object can be achieved by providing at least one position in an arbitrary positional relationship or angle. The present device is particularly effective when the molded product is a fragile material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described with reference to the accompanying drawings.

FIG. 1 is a schematic diagram showing an embodiment of the present invention. Reference numeral 1 denotes a board, and 2 denotes a conveyor, which is fixed on the board 1. Reference numeral 3 denotes a conveyor belt, which is mesh-shaped, has a high opening ratio, and has a shape that allows easy passage of air. Mounting plates 4 and 5 are mounted on the left and right sides of the conveyor. 6 is a nozzle for blowing air intermittently or continuously,
It is held by a column 7 established on the mounting plate 4 and connected to an air supply source (not shown). On the other hand, reference numeral 8 denotes a pair of guide plates, which are provided at a larger interval than the molded product 9 and prevent the molded product 9 from moving in the horizontal and vertical directions due to the pressure of air. The molded article 9 is placed on the conveyor belt 3 from the side opposite to the air blowing nozzle 6 under the guide plate 8 and is supplied in a line by a pair of alignment plates 10. The guide plate 8 and the alignment plate 10 are the mounting plates 4 and 5
Although fixed above, the interval can be adjusted as necessary according to the size of the molded article 9.

Since the apparatus of the present invention is configured as described above, when the conveyor 2 is operated, the molding 9 is continuously transferred below the air blowing nozzle 6. Then, air is intermittently or continuously blown from the upper side to the lower side of the molded article 9 from the air blowing nozzle 6 to blow off and remove the powder adhering to the molded article 9. This operation is repeated as necessary. It is needless to say that this device can be a fully automatic device.

[0012]

As described above, according to the present invention, the powder adhering to the molded product can be efficiently removed without damaging the molded product and without manual operation. Further, the powder can be continuously removed, and the molded product is not damaged during the transfer.
