[Prior art]

 Various proposals have been made as a device for handling a plate-like body horizontally placed on a conveyor or the like, for example, a glass plate by an adsorption plate, and leaning and transferring the glass plate on a trolley or a pallet. No. 14501 discloses that a chuck frame having a large number of vacuum chucks is lowered from above to adsorb a glass plate, and a chuck frame lifting device operates until the vacuum chuck reaches a certain degree of vacuum. A hoist for hoisting a glass plate or a plate-like body is disclosed in which the chuck frame is rotated and the glass plate is obliquely stacked while being moved in a required direction after the operation of the lifting device. As an improvement on the reversal of the device for adsorbing the particles, for example, in Japanese Utility Model Publication No. 44-21533, a bogie mounted on a rail and allowed to move laterally along the rail, From the horizontal beam, which is vertically hung vertically from the horizontal beam and has fan gears on both sides, an elevator drive machine supported on the carriage and whose lower end working end is connected to the horizontal beam, and a proper number of suction cups and the fan gear. A suction frame equipped with a fan-shaped gear that meshes with, a linking rod that pivotally mounts the above-mentioned suction frame to the horizontal beam, an arm integrally formed with the linking rod, and one end that is pivotally attached to the arm and the other end is long. A vertical rod pivotally attached to a pin on the trolley via a hole is used to raise the horizontal beam by the elevating and lowering machine so that the suction frame is initially in a horizontal position until the pin contacts the lower end of the long hole. A suction reversal device such as a steel plate is constructed so that the suction frame is automatically raised to a substantially vertical position while rising by the cooperative operation of the vertical rod arm, the connecting rod and the fan gear. Disclosed Further, in a conventional device as shown in FIG. 3, a sprocket 12 is provided on a shaft portion for rotating a beam 15 having a suction plate 16 attached thereto, and both ends of a chain 20 meshing with the sprocket are stretched in a suspended manner. There is known a device which is connected to the rod ends of two cylinders 19 ', 19' to be installed, and which rotates the shaft portion to about ± 90 ° via the sprocket 12 by the operation of descending and ascending movement of the rods against each other. ing.

[Problems to be solved by the device]

 In the case of Japanese Patent Publication No. 40-14501 of the above-mentioned prior art, a large area, heavy glass plate is transferred to the glass mounting table, and thus the equipment must be upsized, weighted and complicated. Therefore, since the chuck frame for reversing the glass plate is pivotally attached to one side of the lower end of the elevating cabinet by the pivot, the reversing direction is limited to transfer only on the glass mounting table placed on the pivot side. However, the one disclosed in Japanese Utility Model Publication No. 44-21533 has a simple structure in which the suction frame for sucking a steel plate or the like is automatically moved to a substantially vertical position while being raised by the operation of the cylinder. Similarly, there is a problem that the substantially vertical posture is limited to one side and it cannot be transferred on the glass mounting subject placed on the other side. Rotate in the desired direction The rotation angle can also be obtained, but the forward / reverse operation of the rod by a pair of cylinders causes a back pressure in the cylinder due to the rod speed control adjustment valve provided in the driven cylinder, causing an instantaneous time difference in the operation of the cylinder rod. The load on the chain that causes the sprocket to rotate due to the time lag acts as a load that pulls up the shaft of the sprocket through the sprocket. However, there is a problem in that the deflection causes damage to the glass plate during reverse transfer or damage to the bearing portion.

[0004]

[Means for solving problems]

 In view of such a problem, the present invention has a simple structure, enables simple drive transmission, and allows the reversal angle up to about ± 90 °, and for the purpose of providing a maintenance-free device, reciprocates along a rail installed above. A hoist portion is provided on a cart that can traverse freely, and a bearing portion is provided in the hoist portion below a main frame that can be suspended vertically via a subframe, and a shaft that locks a sprocket on the bearing portion. In the plate-shaped body transfer device, in which a plurality of suction discs for sucking the plate-like body are attached to the shaft-mounted beam through the parts, and the sprocket is rotated to invert the beam, the main body above the sprocket is provided. A rotatable idler that is axially attached to the frame is provided, and a chain that meshes with the idler and the sprocket is stretched via a connecting member, and is fixed to the main frame with the connecting member to move up and down. A transfer device for a plate-like body, characterized in that a cylinder for closing is provided in a suspended manner.

[0005]

[Action]

 The horizontal beam that supports the plate-like object by suction from multiple points on the hoist and suspension main frame from the truck is supported by a horizontal beam that traverses the truck to one side of the pallets placed on both sides. The plate-shaped body is moved to a predetermined height by the operation, and the sprocket is rotated through the idler and the tension chain by the upward or downward operation of the cylinder rod suspended in the main frame. , The beam axially attached through the shaft portion that locks the sprocket together with the plate-like body that is adsorbed to the suction plate rotates approximately 90 °, and the plate-like body moves in the transverse movement of the carriage and the fine movement of the hoist portion. When the suction plate is moved to the pallet and the suction plate is released, the plate-like object is transferred onto the pallet, and the cylinder, hoist section, and bogie are returned to the original state, and the next plate-like object is sucked. Dolly, cylinder work It is possible to transfer the plate-shaped body on a pallet placed in the opposite direction if the direction of the opposite.
