Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing device, and more particularly to a polishing device for effectively removing burrs and the like generated in products when metal is pressed.

[0002]

2. Description of the Related Art In many conventional automatic polishing apparatuses, as shown in FIG. 6, an object to be polished such as a press-worked product is placed on a conveyor belt 42 while being conveyed, and the polishing belt 41 is attached thereto.
The other surface of the object was polished by pressing other polishing means.

In such a polishing apparatus, since the polishing means rotates at high speed and comes into pressure contact with the object, there is a possibility that the object may be flipped away in the rotational direction by the rotational movement thereof, in order to prevent this. , A means for fixing the object on the belt was needed. For example, a strong magnet 43 at the bottom of the belt
The object was held on the belt by the magnetic force of the magnet, and this was polished.

[0004]

However, the above-described conventional structure cannot be applied to a material that does not attract the object by magnetic force, such as aluminum, and the object is attracted by magnetic force. Even in the case of materials, there is a problem that it cannot be applied to products that do not like remanence. In addition, even if there is a material such as an iron material that does not have these problems, in the relationship between the rotation speed and pressure of the polishing belt and the holding force due to the magnetic force, if the former force exceeds the latter, the object is flipped, If the force of the former is much smaller than the latter, it will not be sufficiently polished, so
There was a problem that it was difficult to control, such as the need to maintain a delicate balance between the former and the latter in order to perform proper polishing.

Further, in the above-mentioned conventional structure, it is possible to polish a flat object, but when polishing a three-dimensional object having unevenness, the object is inclined on the conveyor. Therefore, there is a problem that the object cannot be uniformly polished.

The present invention solves the above-mentioned conventional problems, and makes it possible to automatically hold an object, regardless of the material used, while holding it easily during polishing. It is also an object of the present invention to obtain a polishing apparatus that can uniformly polish an object regardless of the shape of the object.

[0007]

Means for solving the above problems according to the present invention are, as described in the above-mentioned claims, a conveying means for feeding an object in a traveling direction and a conveying means for slanting in the traveling direction. The polishing device and the transporting means are composed of a polishing means for moving the polishing surface and polishing the object, and a guide provided in parallel with the traveling direction for restricting the movement of the object in the same direction as the polishing surface. A belt conveyor that conveys an object by contacting it from its upper part, and a polishing means is a belt-shaped polishing means that contacts the lower part of an object and polishes it, and the conveying means is an elastic member provided on the belt. Including those that hold objects by.

[0008]

In the polishing apparatus of the present invention, the object is automatically moved by the conveying means for feeding the object in the traveling direction. The polishing means moves the polishing surface in a direction oblique to the traveling direction of the conveying means to convey the object, and the polishing means for polishing the object is an object in a direction oblique to the traveling direction of the object moved by the conveying means. To polish.

The guide, which is provided in parallel with the traveling direction and regulates the movement of the object in the same direction as the polishing surface, prevents the object from moving in the polishing direction of the polishing means, and
The object is guided so that the object moves in the traveling direction.

[0010] The object is polished while moving in the traveling direction by the movement of the transporting means, the movement of the polishing means, and the regulation by the guide, and is discharged in the forward direction after the polishing is completed.

FIG. 4 is a sectional view taken along the line AA of FIG. 3 for explaining the function of the present invention. In the figure, 1 is a polishing device, 2 is a conveyor belt, 3 is a polishing belt, 4 is a guide, 5 is an inlet conveyor, 6 is an outlet conveyor, 7 is a pressing cylinder, and 8 is a pressing plate.

In the example shown in FIG. 3, the object to be polished is placed on the entrance conveyor 5 with the polishing surface facing down and conveyed sequentially. Since the entrance conveyor 5 is rotated to the right by a drive device (not shown) in the figure, the object to be polished is conveyed rightward in the figure and moved to the lower part of the conveyor belt 2. The conveyor belt 2 is rotated counterclockwise by a drive device (not shown) at substantially the same speed as the entrance conveyor, contacts the polishing object from above, and urges the polishing object in the right direction in the figure. Therefore, even after the object to be polished is separated from the entrance conveyor, the object to be polished is moved to the right in the figure. The polishing belt 3 is installed obliquely with respect to the traveling direction of the conveyor belt 3 and rotates rightward at a high speed in FIG. When the object to be polished is removed from the entrance conveyor, it moves onto the polishing belt 3, and the lower part of the object to be polished is rapidly polished by the polishing belt 3. At the same time, the object to be polished is strongly urged in the rotating direction of the polishing belt 3. Then, it tries to move in a direction deviating from the traveling direction of the conveyor belt. The guide 4 contacts the end of the object to be polished and restricts the object to be polished from coming off the traveling direction of the conveyor belt. Therefore, the lower part of the object to be polished is conveyed in the traveling direction of the conveyor belt 3 while the lower part thereof is being polished, and when the polishing is completed by removing from the polishing belt 3, it is moved onto the exit conveyor 6 and discharged from the apparatus. It

When the object to be polished is on the polishing belt 3, a pressing plate 8 interlocked with a pressing cylinder 7 installed above the conveyor belt 2 moves the conveyor belt 2 downward so that the lower part can be efficiently polished. , And an appropriate pressure is applied to the object to be polished.

As shown in the side view of FIG. 5, the conveyor belt 2 of this example is composed of a belt body 22 and a large number of elastic plates 23 connected to the belt body 22. Therefore, even if the non-polished surface to be polished has irregularities, the irregularities can be absorbed and the polished surface to be polished can be uniformly applied to the polishing belt, and polishing can be achieved uniformly. Depending on the object to be polished, the structure of the conveyor belt does not need to have a complicated structure as in this embodiment, and the structure that absorbs irregularities also employs an elastic member such as another synthetic resin or a coil spring-like elastic member. It is possible to adopt an arbitrary configuration such as employing a member, and it is not limited to the configuration of this embodiment.

Further, the constitution of the polishing means and the conveying means is not limited to the constitution of the above-mentioned embodiment, and the positional relationship can be reversed upside down, and another known polishing means is adopted as the polishing means. It is also possible.

[0016]

As described above, the polishing apparatus of the present invention is capable of automatically holding an object while easily holding it at the time of polishing, regardless of the material used. The object can be polished uniformly regardless of the shape, and a large number of objects can be polished extremely rapidly and continuously.
