SUMMARY OF THE INVENTION In order to achieve the above-described object, the present invention provides a method of positioning a window plate by positioning means, holding the positioned window plate by a transfer device, and pre-setting a frame member. A method of manufacturing a window plate with a frame material, which is transferred to a vicinity of a molded mold, and the frame material is protruded from the mold and attached to a peripheral portion of the window plate material, wherein the window material is positioned. Various members are attached to predetermined positions of the window plate by a mounting device disposed in a predetermined positional relationship with respect to the positioning means, and the window plate is held by the transfer device with the various members attached. And a method for producing a window plate with a frame, wherein the plate is transferred to the vicinity of the mold.

In order to accurately attach the frame material to the window plate,
It is necessary to accurately transfer the window plate to a predetermined position with respect to the mold by the transfer device. For that purpose, it is necessary to accurately hold a predetermined position of the window plate material by the transfer device.
Detecting the displacement of the window plate and finely adjusting the transfer device so that the predetermined position of the window plate is held by the transfer device, the equipment becomes large,
Productivity decreases. Therefore, it is practical to position the window plate before being held by the transfer device at a predetermined position, and to hold and transfer the window plate by a transfer device that performs a certain operation. For this reason, the window plate before being held by the transfer device is positioned at a predetermined position by the positioning means.

Thus, according to the present invention, various members can be accurately, easily and quickly attached to the window plate. Further, the frame member can be accurately, easily and quickly attached to the window plate to which various members are attached.

In the present invention, the window plate is positioned by the positioning means in a substantially horizontal state such that the inner side surface of the window plate is on the lower side, and various members are mounted by a mounting device disposed below the inner side surface of the vehicle. Attach it to a predetermined position on the inside surface of the vehicle, hold the window plate with the various members attached to it by the transfer device, transfer it to the upper part of the mold while keeping it approximately horizontal, and project the frame material upward from the mold to Preferably, it is attached to the peripheral edge of the side surface. In this specification,
The “substantially horizontal state” includes the following meaning in addition to the state in which the plane direction of the flat window plate is oriented in a direction perpendicular to the direction of gravity. First, although the window plate is curved two-dimensionally or three-dimensionally and its plane direction is not necessarily perpendicular to the direction of gravity, various members and frame members for the window plate are used. The "horizontal horizontal state" includes a state in which the window plate is kept substantially horizontal in a well-balanced manner so as not to impair the mountability of the window. The “horizontal horizontal state” includes a state in which the plane direction of the flat window plate is not perpendicular to the direction of gravity within a range that does not impair the attachment of various members and the frame member to the window plate. It is.

[0010] In this case, since the mounting direction of the various members by the mounting device is the same as the direction in which the frame material protrudes from the mold, the window plate material is inverted during the transfer of the window plate material by the transfer device. No need. Therefore, the structure of the transfer device can be simplified. In addition, since the frame member is projected upward from the mold, the frame member can be easily and reliably attached to the window plate.

Although the form of the positioning means is not limited, a plurality of positioning pins or the like abutting on a plurality of positions on the peripheral end surface forming the outer periphery of the window plate can be exemplified. The positioning pin preferably has a cylindrical outer peripheral surface, and the outer peripheral surface supports the peripheral end surface of the window plate material by point contact or line contact. In addition, from the viewpoint of being compatible with window plates having various sizes and shapes, it is preferable that at least one of the plurality of positioning pins is movable in a direction perpendicular to the axial direction. . Although the form of the transfer device is not limited, a suction transfer device that suctions and holds the window plate material by the suction unit can be exemplified. Generally, the frame member and various members are attached to the inside surface of the window plate. In particular, various members are often attached to the peripheral portion of the vehicle inner side surface so as to be covered with a dark-colored coating material provided on the vehicle inner side surface at the peripheral portion of the window plate material and not to be seen from the vehicle outside. Therefore, it is preferable that the outer side surface of the window plate is sucked and held by the suction transfer device so as not to hinder the work of attaching the frame member and various members to the inside surface of the window plate. Although the form of the mounting device is not limited, a pressing device provided with a pressing portion that can be protruded and retracted (movable forward and backward) can be exemplified. As the pressing device, a holding portion capable of holding various members is provided in the pressing portion, and the pressing portion performs a projecting and retracting operation once in a state where at least one of the various members is held in the holding portion, so that the various members can be window-mounted. What can be attached to a board for use is preferred.

Examples of the window plate material include a transparent or translucent glass plate and a resin plate. A chromatic glass plate or a resin plate may be used as long as it has sufficient transparency. Examples of the glass plate include a single glass plate and a laminated glass.
Further, the glass plate may be provided with a functional coating such as a strengthening treatment or a heat ray reflective film.
