Abstract

PROBLEM TO BE SOLVED: To transfer a glass plate in a vertical attitude so that glass plates are not brought into contact with each other when a plate-like body such as the glass plate is drawn out of a loaded truck with simple constitution by drawing out the sucked glass plate from the truck, and feeding it on a conveyor in the vertical attitude. SOLUTION: A glass plate feeding device elevates by an elevating/lowering means 30 a lower end part of a glass plate G loaded in the vertical direction while separated one by one by a rod erected on a loading truck 1, and then, sucks a lower corner part of the glass plate G by a sucking means. The glass plate G which is sucked and drawn from the loading truck 1 by a suction part reciprocating means is transferred to a glass plate carrying device to carry the glass plate G and to regulate the angle of inclination of the glass plate G by an attitude regulating means so as to meet the angle of inclination in the next process. Every time one glass plate G is drawn out, the loading truck 1 is moved by the loading pitch of the glass plate G by a truck pitch feeding means.

[0024]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a glass sheet supply apparatus according to the present invention. First, as shown in FIG. 4, a loading truck on which the glass plates are separated from each other is placed in the truck supply unit 65. After contacting the stopper 66, the loading cart 1
Is turned by 90 degrees and transferred to the bogie pitch feed means 60 by a drive mechanism (not shown).

As shown in FIG. 3, guide rolls 2, 2 provided on the lower center line of the loading truck 1 regulate the traveling route by a gap in the roller guide 61 of the truck pitch feeding means 60, and are guided by the truck conveyor 62. The loading cart 1 runs at the loading interval pitch of the glass plates.

The glass plate facing the outermost side on the loading cart stops at a predetermined position, that is, at the position of the transfer roll 55 of the glass plate transfer means 50. The lifting roll 32 of the lifting means 30 is brought into contact with the lower end of the outermost glass plate between the auxiliary roll of the loading cart 1 and the bottom plate, and the lifting roller 32 is raised by the lifting cylinder to slightly lift the glass plate.

As shown in FIGS. 5 and 6, the pressing cylinder 15 of the suction means 10 is protruded so that the suction pad 11 is pressed against the lower corner of the glass plate and sucked by a vacuum source (not shown). The glass plate is transported so that the glass plate is extracted from the loading cart 1 by the means 20. At this time, the glass sheet G is simultaneously conveyed by the glass sheet conveying means 50, and the glass sheet G is supported on the lower end side of the glass sheet by conveyance rolls 55, 55,. Rolls 56, 56, ...
56 ', 56',...

When the transfer of the glass plate G onto the inclined conveyor by the glass plate conveying means 50 and the suction part reciprocating means 20 is completed, the suction pad 11 releases the glass plate and returns to the loading cart side. Further, in order to adjust the inclination angle of the conveyor in accordance with the angle of the inclined conveyor in the next process, the attitude adjusting cylinder 41 of the attitude adjusting means 40 is operated to incline the glass plate G in the upright state by about 6 degrees from the vertical direction. . The inclined glass sheet G is again carried out by the glass sheet conveying means 50, and when the carrying out is completed, the posture adjusting cylinder 41 is operated to stand up, and the next glass sheet G is received.

The truck pitch feed means 60 is also a glass plate G.
Each time one sheet is removed, the carriage is transported in a pitch unit so that the outermost glass plate G always stops at a predetermined position.

A dog for identifying a truck number is attached to the loading truck 1 so that the dog can be read by a sensor, and when loading onto the loading truck 1, a glass plate G of what size and on which truck is placed. If the information as to whether or not the material is loaded can be input and stored in a computer or the like, confusion can be avoided at the time of processing in a later process, and the work can be performed smoothly.

Although the preferred embodiment has been described above, the present invention is not limited to this, and various applications can be considered. The drive motor 22 of the suction unit reciprocating means 20 may be replaced by driving by an air cylinder, and the attitude adjusting cylinder 41 of the attitude adjusting means 40 may be replaced by driving by a motor.

Further, if the glass plate conveying means 50 and the attitude adjusting means 40 are divided into two and used as shown in FIGS. 1 and 4 according to the glass size, the processing tact becomes faster and the efficiency is improved. . That is, when the glass plate is small, only the conveyor near the truck is operated.

Alternatively, a frame for preventing the glass sheet G from falling over the top of the back frame may be provided so that the glass sheet G on the transport roll 55 of the glass sheet transport means 50 does not fall over.

Alternatively, the loading cart 1 is supplied to the truck pitch feeding means 60 in a direction perpendicular to the drawing direction of the glass plate G as shown in FIG. 4, but is supplied in the drawing direction of the glass plate G. You may do it.

Alternatively, the direction of supply of the carriage from the carriage supply section 65 and the direction of removal of the carriage take-out section 70 are set to be perpendicular to the direction of carriage transportation of the carriage pitch feed means 60, but are assumed to be the same direction as the carriage transportation direction. Is also good.

Alternatively, a desired glass plate G is pressed from the side of the loading truck 1 on the truck pitch feeding device 20 opposite to the side of the suction device 10 where the suction device 10 is located, and is sucked by the suction pad 11 and extracted. Is also good.

Alternatively, the plate G is a glass plate, a panel material, or the like, and the glass plate is a single plate such as a tempered glass plate, a semi-tempered glass plate, a green plate, or a plurality of tempered glass plates, or a pair of tempered glass plates. Combining glass and raw glass
The target is an intermediate film such as VB or EVA or a laminated glass adhered by resin injection, and a glass plate to which a scattering prevention resin film is adhered.

[0038] The rod 4 of the loading cart 1 is formed by applying Japanese Patent Application No. Hei 9-2.
As described in Japanese Patent No. 56769, a rod-shaped or pipe-shaped metal having a strength enough to withstand the weight of a single glass plate G, a non-rusting metal such as stainless steel, or a rubber or Since it was covered with a resin tube such as vinyl chloride, loading the glass plate,
The glass plate is not damaged or broken when unloading.

The loading truck 1 used in the present invention is capable of loading about several tens of glass plates G from small size to large size. The size is not limited to the same size, but may be different sizes and different thicknesses. It may be mixed.

[0040]

According to the present invention, it is possible to transfer a plate-like body such as a glass plate in a vertical configuration so that the glass plates do not come into contact with each other when the plate-like body is removed from the loading cart.

Further, since the lower end is slightly raised by the elevating means at the time of extracting from the loading truck, the lower end of the glass plate rises from the floor bar of the loading truck at the time of extracting, and the contact area is reduced. Extraction became easy.

Further, since the sheets are automatically picked up one by one by being sucked by the suction pads, the sheets can be picked up without damaging the glass plate surface, and the working efficiency and production efficiency are improved.
