The projecting plate 21 comes into contact with the bolt 19 with a delay from the shaft 6 that rotates via the member 7 to rotate the base 16, but the lower stage base 17 on the base moves vertically. Nda 22 and the vertical movement guide 23,2
3, the vertical movement guide and the vertical movement cylinder 2 are provided.
An upper stage base 24 is attached to the rod end of 2, and a transverse cylinder 25 projecting and reciprocating in the center direction of the roll conveyor 1 is sandwiched between the upper stage bases, and transverse guides 26 are provided on both sides thereof.
26, the traverse guide and traverse cylinder 25
A bottom plate 28 having a bottom stopper 27 is attached to the rod end of the base plate, and a rail 29 is fixed to the side surface of the bottom plate on the conveyor 1 side, as shown in FIG. A bottom auxiliary stopper 32 that bends in a Z shape and is fixed to the end of the slide shaft 30 is attached to a mounting member 33 that is mounted on the rail and moved, is traversable by a slide shaft 30, and is positioned and fixed by a lock member 31.
The bottom end of the bottom auxiliary stopper is the bottom stopper 27.
Positioning is performed at the same height as in the horizontal direction by the slide shaft 30.

Means for moving the bottom plate 28 up and down,
The vertical moving cylinder 22 on the lower base is the glass plate
The size of the bottom plate 27 may be installed as required. A cushioning material, such as a rubber material, is attached to the side surfaces of the bottom side stopper 27 and the bottom side auxiliary stopper 32 provided on the bottom side plate to cushion the abutting glass plate 2. It is desirable to wear.

The operation of the present invention will be described below. The glass plate 2 is conveyed by the roll conveyor 1 , and the length of the glass plate 2 in the conveyance direction is measured by an encoder (not shown) that generates a pulse signal in synchronization with the rotation of the detection sensor 3 and the roll 9 provided on the upstream side of the conveyor. When the rotation of the roll 9 is stopped, the glass plate 2 is placed at a predetermined position on the conveyor 1.
The bottom plate 28 descends and projects to a predetermined position by the interlocking movement of the vertical movement cylinder 22 and the traverse cylinder 25, and the bottom stopper 27 integrated with the bottom plate and the slide shaft 30 and the rail 2 in advance.
The lower end of the bottom auxiliary stopper 32 whose position is set by 9 is stopped by providing a gap of about 2 mm from the upper surface of the roll 9, and the eccentric cam 14 is rotated by the operation of the interlocking elevation motor 13 to rotate the elevation lever 12. When the lower end is pressed toward the center of the roll conveyor 1 , the L attached to the shaft 6
The shaped member 7, the support rod 8 fixed to the L-shaped member, and the elevating arms 11, 11 ... Installed in parallel with the support rod are rotated around the center of the shaft 6 and attached to the rotating shaft 6. If the projecting plate 21 also comes into contact with the bolts 19 and is pressed to rotate the base 16 with a delay, the lower and upper bases 17 and 24 installed on the base, and the cylinder 2 installed on the base.
2, 25 and the bottom plate 28 supported via the guides 23, 26 also tilts, and the bottom stopper 27 and the bottom auxiliary stopper 32 that are integrated with the bottom plate 28 or attached are also tilted, but at the end of the elevation arm 11. The glass plate 2 supported by the roll 9 which is stopped by lifting and turning,
The free bears 10 provided on the elevation arm 11 slide on the bottom plate 28 side, and the gap between the upper surface of the roll 9 and the lower ends of the bottom stopper 27 and the bottom auxiliary stopper 32 is smaller than the rotation angle of the elevation arm 11. The rotation angle of the bottom plate 28 that tilts following the arm is small, that is, the rotation angle of the shaft 6 is delayed in proportion to the gap between the projecting plate 21 and the bolt 19 fixed to the same shaft 6, and is provided on the base 16. By rotating the bottom plate 28, the gap is narrowed, and the bottom stopper 27 and the bottom auxiliary stopper 32 block the sliding movement to prevent the bottom of the glass plate 2 from protruding from the gap and perform transverse positioning, so that the The backward movement of the elevation arm 11 and the bottom plate 28 tilted by the reverse rotation of the motor 13, the vertical movement cylinder 22, and the traverse system. The bottom plate 28 is separated from the roll 9 by the backward movement of the binder, and the glass plate 2 having the bottom positioned is moved downstream by the drive of the conveyor 1, and a positioning stop device (not shown) provided downstream of the conveyor, such as a glass detection sensor and The highly accurate glass stopping device, which is a combination of a pulse generator and a hard counter, again positions the sheet in the conveying direction, thereby enabling accurate positioning of the deformed glass sheet.

The positioning device of the present invention is effective for positioning a glass plate having a complicated shape with an uneven bottom, for example, a base plate such as an automobile side glass.

[0012]

EFFECTS OF THE INVENTION The sensor is stopped at a predetermined position on the conveyor in the conveying direction, and the stopper of mechanical means adjustable in the transverse direction and the elevation arm for traversing the glass plate position the transverse direction of the bottom of the glass plate. Therefore, even a glass plate having a complicated shape can be positioned, and accurate positioning can always be surely performed by performing positioning in the transport direction again.
