ABSTRACT:
TECHNICAL FIELD
The present invention relates to a machine for bend-breaking a glass plate or the like.
BACKGROUND ART
Glass-plate bend-breaking machines have been proposed in which a press-breaking device is moved within a plane, which is parallel to the surface of a glass plate placed on an endless belt, and along a bend-breaking line formed on the glass plate, while a glass-plate receiving device is moved below the endless belt in correspondence with the movement of the press-breaking device.
In the above-described glass-plate bend-breaking machine, since the placing of the glass plate on the endless belt is effected by a manual operation, in a case such as where a bend-breaking line (main cut line) has been formed in advance on the glass plate in a preceding process, unless the placing is effected by exercising precautions sufficiently, there is a possibility that the glass plate becomes bend-broken at the bend-breaking line, so that this operation entails an extreme danger.
In addition, with the above-described glass-plate bend-breaking machine, a multiplicity of openings are formed in a supporting plate for supporting the endless belt, and press-breaking devices and glass-plate receiving devices are arranged in correspondence with the multiplicity of openings, respectively, and bend-breaking is effected in an apportioned manner in each opening. Consequently, unless a bend-breaking line with a certain measure of depth has been formed, there is a possibility that bend-breaking cannot be effected completely at a position between adjacent openings.
The present invention has been devised in view of the above-described aspects, and its object is to provide a glass-plate bend-breaking machine which is capable of automatically placing the glass plate on a flexible member such as an endless belt without involving a manual operation, and which does not entail a danger in the bend-breaking operation of the glass plate.
Another object of the present invention is to provide a glass-plate bend-breaking machine which is capable of bend-breaking the glass plate reliably along a cut line without a bend-breaking error.
Still another object of the present invention is to provide a glass-plate bend-breaking machine in which even if a single or a small number of openings are provided in a supporting member for supporting the flexible member such as the endless belt, the flexible member is prevented from sagging much.
DISCLOSURE OF THE INVENTION
In accordance with the present invention, the above objects are attained by a machine for bend-breaking a glass plate comprising: a flexible member on which the glass plate is placed; a supporting member for supporting a peripheral portion of the flexible member; a glass plate receiving device disposed below the flexible member and including a glass plate receiving surface for receiving the glass plate from a lower surface of the glass plate by means of the flexible member in a region surrounded by the supporting member; a first moving device for moving the glass plate receiving surface of the glass plate receiving device within a plane, which is parallel to the surface of the glass plate; a press-breaking device disposed above the endless belt and including a pressing surface for press-breaking the glass plate which is placed on the flexible member and on which a cut line is formed, along the cut line, in the region surrounded by the supporting member; a second moving device for moving the pressing surface of the press-breaking device within a plane, which is parallel to the surface of the glass plate; and a carrying-in and carrying-out means for carrying the glass plate to be subjected to bend-breaking into the region surrounded by the supporting means and for carrying the glass plate subjected to bend-breaking out of the region surrounded by the supporting member, the first and second moving devices operating such that a moving position of the pressing surface corresponds to a moving position of the glass plate receiving surface in a press-breaking operation of the pressing surface of the press-breaking device for the glass plate above the endless belt in the region surrounded by the supporting member.
In accordance with the present invention, the above objects are also attained by a machine for bend-breaking a glass plate comprising: a flexible member on which the glass plate is placed; a supporting member for supporting a peripheral portion of the flexible member; a plurality of glass plate receiving devices each disposed below the flexible member and including a glass plate receiving surface for receiving the glass plate from a lower surface of the glass plate by means of the flexible member in a region surrounded by the supporting member; a plurality of first moving devices each for moving the glass plate receiving surface of the corresponding glass plate receiving device within a plane, which is parallel to the surface of the glass plate; a plurality of press-breaking devices each disposed above the endless belt and including a pressing surface for press-breaking the glass plate which is placed on the flexible member and on which a cut line is formed, along the cut line, in the region surrounded by the supporting member; a plurality of second moving devices each for moving the pressing surface of the corresponding press-breaking device within a plane, which is parallel to the surface of the glass plate; and a carrying-in and carrying-out means for carrying the glass plate to be subjected to bend-breaking into the region surrounded by the supporting means and for carrying the glass plate subjected to bend-breaking out of the region surrounded by the supporting member, the first and second moving devices each operating such that a moving position of the corresponding pressing surface corresponds to a moving position of the glass plate receiving surface in a press-breaking operation of the pressing surface of the corresponding press-breaking device for the glass plate above the endless belt in the region surrounded by the supporting member.
Further, according to the present invention, the above objects are also attained by a machine for bend-breaking a glass plate comprising: a flexible member on which the glass plate is placed; a supporting member for supporting the flexible member; a glass plate receiving device including a glass plate receiving surface for receiving the glass plate from a lower surface of the glass plate by means of the flexible member; a first moving device for moving the glass plate receiving surface of the glass plate receiving device; a press-breaking device including a pressing surface for press-breaking the glass plate; a second moving device for moving the pressing surface of the press-breaking device; and a carrying-in and carrying-out means for carrying the glass plate to be subjected to bend-breaking in and for carrying the glass plate subjected to bend-breaking out; the first and second moving devices operating such that a moving position of the pressing surface corresponds to a moving position of the glass plate receiving surface in a press-breaking operation of the pressing surface of the press-breaking device for the glass plate.
In one aspect of the present invention, the first moving device includes a moving mechanism for moving the glass plate receiving surface in one direction and in another direction intersecting with the one direction, within the plane, which is parallel to the surface of the glass plate, and in another aspect, the second moving device includes a moving mechanism for moving the pressing surface in one direction and in another direction intersecting with the one direction, within the plane, which is parallel to the surface of the glass plate.
In another aspect of the present invention, the glass plate receiving surface has a movable supporting surface capable of advancing and retracting with respect to the lower surface of the glass plate for supporting the glass plate by means of the endless belt, and the glass plate receiving device including an advancing/retracting means for advancing an
