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 polishing a plate-like object such as a glass plate.

[0002]

2. Description of the Related Art A conventional apparatus for polishing a glass plate is as follows.
Polishing the glass plate placed on the table by reciprocating under the rotating polishing tool installed in the fixed position,
It is configured to remove irregularities, undulations, and the like on the surface of the glass plate, improve flatness, and make the thickness uniform.

[0003]

However, this conventional polishing apparatus can polish only one glass plate at a time, resulting in poor polishing efficiency. Further, in order to prevent the glass plate from being blown off by a load received from the rotary polishing tool during polishing (hereinafter, this is referred to as floating), a special adhesive is used when placing the glass plate on the table. A glass plate is applied and fixed on a table, and after polishing, the glass plate is peeled off from the table to remove the special adhesive adhering to the glass plate. As described above, in the conventional polishing apparatus, the above operation must be performed every time the glass plate is polished, and there is a problem that the operation efficiency is very poor. Furthermore, in such a method of fixing a glass plate, if the amount of the special adhesive applied is insufficient, the glass plate moves loosely during polishing, and conversely, if the amount of the applied adhesive is large, the glass plate is used for subsequent peeling and removing operations. It takes time and causes various problems in terms of workability.

SUMMARY OF THE INVENTION It is an object of the present invention to continuously polish a plate-like object, and to obviate any troublesome work for fixed mounting at the time of polishing the plate-like object. It is an object of the present invention to provide a continuous polishing apparatus for a plate-like object having a function of preventing the occurrence of a problem.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a transport conveyor for continuously placing and transporting each plate-like object in one direction, and a plate transported by the transport conveyor. A rotary polishing tool having a polishing work width substantially equal to the width of the object, a side guide installed on both sides of the conveyor and guiding and regulating both widthwise sides of the plate-like object conveyed by the conveyor, and a conveyor And a pressing roller for preventing the plate-like object conveyed in the above from moving in the conveying direction.

[0006] With the above structure, the plate-like object on the conveyor is prevented from moving in the width direction by the side guide against the load from the rotary polishing tool, and the floating motion in the conveying direction is controlled by each rotary polishing tool. Is prevented by the pressing rollers before and after. Since the rotary polishing tool is configured to have a polishing operation width substantially equal to the width dimension of the plate-shaped object, the rotary polishing tool can uniformly polish over the entire length of the plate-shaped object in the width direction. Therefore, the plate-like object is securely fixed and placed continuously without the need for the application of a special adhesive and the peeling-off operation after the completion of polishing as in the related art when the plate-like object is carried into the conveyor. It is designed to be polished.

FIG. 1 is a side view showing an embodiment of the apparatus of the present invention, FIG. 2 is a plan view thereof, and FIG.
2 is an enlarged plan view of a main part in FIG. 2, wherein 1 is a plate-like object such as a glass plate, 2 is a conveyor, 3 is a rotary polishing tool, Indicates a side guide, 5 indicates a pressing roller, 6 indicates a carry-in conveyor, and 7 indicates a carry-out conveyor.

The plate-like material 1 is continuously carried in and supplied from the carry-in conveyor 6 onto the conveyor 2 at appropriate intervals. The transport conveyor 2 has a configuration in which a transport belt 2c is stretched endlessly between a driving pulley 2a and a driven pulley 2b, and the driving pulley 2a is rotated at an appropriate speed by a motor (not shown). Each of the loaded plate-like objects 1 is continuously placed and conveyed in one direction to pass through the position where each rotary polishing tool 3 is arranged. The upper surface is sequentially polished, and the polished one is sequentially carried out from the carry-out conveyor 7. In addition, a plate 2d for supporting the polishing pressure applied to the plate-like material 1 from the lower surface of the transport belt 2c as a backup is disposed in the arrangement range of each rotary polishing tool 3.

The rotary polishing tools 3 are arranged at appropriate intervals in the conveying direction of the conveyor 2 and have a polishing operation width substantially equal to the width dimension w of the plate-like object 1 conveyed by the conveyor 2.
A disc-shaped one that rotates a large disc-shaped one at its center is arranged.

Side guides 4 are provided on both sides of the conveyor 2, and are notches so as to guide and restrict both sides in the width direction of the plate-like object 1 conveyed by the conveyor 2 and to prevent interference with the rotary polishing tool 3. The case where the portion 4a is formed is illustrated. In the case where the thickness of the plate-shaped object 1 is large, the thickness of the side guide 4 may be partially or entirely smaller than the thickness of the plate-shaped object 1 instead of forming the notch 4a. Good. In FIG. 2, the notch 4 b is provided in the side guide 4 at the position of the holding roller 5 to prevent interference with the holding roller 5. However, instead of providing such a notch 4 b, the holding The pressing width of the roller 5 may be smaller than the guide regulation width of the side guides 4 on both sides. In this way, the side guide 4 can be formed continuously without having to provide a cutout at the installation position of the pressing roller 5.

The pressing roller 5 prevents the plate-like object 1 conveyed by the conveyor 2 from moving in the conveying direction.
In this embodiment, it is disposed on both sides of the rotary polishing tool 3, and the bearings 5a, 5a on both sides of each pressing roller 5 are equipped with elastic springs 5b, 5b for applying downward pressing force. . Although the arrangement of the pressing roller 5 is not limited to the above, in order to more reliably fix and place the plate-like object 1, at least 2 It is preferable to arrange the pressing roller 5 so as to abut on the location. In addition, it is preferable that the pressing rollers 5, 5 on the loading side and the unloading side of the plate-like material 1, among the disposed pressing rollers 5, are positively driven.

The embodiment of the apparatus according to the present invention has the above-mentioned configuration, and the operation will be described below. The plate-like object 1 is a carry-in conveyor 6
, Is continuously carried in and supplied to the conveyor 2 at appropriate intervals, and is sequentially fed and polished by the conveyor 2 from the start end to the end of the arrangement group of the rotary polishing tools 3, and the polished one is sequentially carried out from the unloading conveyor 7. You. During this polishing operation, the play in the width direction of the plate-like material 1 due to the polishing load acting on the plate-like material 1 to be polished by each rotary polishing tool 3 is prevented by the side guides 4 and 4, and the play in the transport direction is prevented. It is prevented by the pressing roller 5.

The apparatus of the present invention is applicable to polishing of glass plates, ceramic plates, metal plates, plastic plates, and other plate-like objects.

[0014]

According to the present invention, a plate-like object can be continuously and efficiently polished, and no troublesome work is required for fixed mounting of the plate-like object, and the floating of the plate-like object during polishing can be ensured. It is possible to provide a continuous polishing apparatus for a plate-like object having a function of preventing the occurrence of a sheet.
