BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a glass plate take-out device is provided with a base frame portion attached to the tip of an arm which is movable and rotatable, and glass plate adsorbing and carrying means is attached near the four corners of the base frame portion. The glass plate adsorbing and supporting means is known to have a glass plate adsorbing tool at its tip, as shown in the proposal.

However, in the glass plate adsorbing and supporting means according to the present invention, each glass plate adsorbing tool is close to the glass plate,
Since the advancing / retreating adjusting means is provided so as to be able to adjust the separation, and each of the glass plate suction tools can be operated independently, it becomes easier to attach the next glass plate, that is, release the blocking.

Further, in the present invention, when the one glass plate suction tool sucks a glass plate and pulls it out, the glass plate is bent by pressing a proper place in the central portion of the glass plate surface by pressing and tapping means. Or by further knocking by pressing / tapping means, that is, by repeatedly giving a light impact, the adhesion of the next glass plate can be prevented.

Further, when the glass plates are brought into direct contact with each other, they are often chemically bonded to each other by the action of mainly alkaline components existing in the glass and moisture in the air to form an adhesive state (in this state, the glass plates are peeled off from each other. In some cases, interleaving paper or powder-like inclusions are usually interposed between the glass plates to prevent this, but when interposing the interleaving paper, it is necessary to eliminate this. The lower end of the frame portion is provided with an interleaving sheet adsorbing means that adsorbs and holds the interleaving sheet and is capable of advancing and retracting.

As proposed in Japanese Patent Application No. 5-161688 relating to the present applicant, air is provided between a glass plate to be taken out at a proper position at the upper end or side end of the base frame and the next glass plate as auxiliary means. You may make it attach an air blower in order to spray.

Further, there are various glass plate sizes, and it is desirable that the glass plate adsorbing tool in the glass plate adsorbing and supporting means is arranged so as to correspond to the four corners of the glass plate as much as possible. As one of the means, each glass plate adsorption supporting means can be provided with a slide adjusting mechanism for moving along the surface of the base frame portion.

It is time-consuming and time-consuming to move each of the glass plate adsorption / holding means in accordance with the size of the glass plate. Therefore, as a more preferable means, it is desirable to be able to move one glass plate adsorption supporting means. The one glass plate adsorbing and supporting means is arranged to first draw out one corner of the glass plate as described later.

The interleaving paper adsorbing means 15 has an advancing / retreating mechanism, for example, an air cylinder 17 so that the suction end 16 can be freely moved forward / backward, and as described in Japanese Patent Application No. 3-106374 proposed by the present applicant. Lifting mechanism for paper suction means
It is preferable to provide (not shown).

The glass plate on the stacker is taken out by the following general operation procedure, and one situation is shown in FIGS. 2A and 2B. 2A and 2B, the respective operation mechanisms such as the advancing / retreating adjusting mechanism of the glass plate adsorbing and supporting tool and the sliding adjusting mechanism of the glass plate adsorbing and supporting means are omitted.

After the glass plate take-out device 1 is made to face the glass plate G1 on the loading tool P by operating the robot arm 2,
Each of the glass plate adsorbing and supporting means 6a, 6b ---- adheres the suction members 7a, 7b, ---- at its tip to the glass plate G1 by driving the advancing / retreating mechanism (air cylinder) to suck it.

Next, the glass plate adsorbing tool in the slide-adjusted glass plate adsorbing means 6a facing one end near the lower side of the glass plate G1 is pulled back to pull out the glass plate front portion. At that time, the next glass plate often comes into close contact with the blocking phenomenon described above and is pulled out together, but in order to prevent this, the pressing / tapping means 9 is driven under the drive of the advancing / retreating adjustment mechanism to the surface of the glass plate G1. Press the glass plate G1
The next glass plate G is released by bending. Alternatively, the adhering of the next glass plate may be released by further repeatedly advancing / retreating the pressing / tapping means 9 and knocking.

Therefore, the glass plate adsorption supporting means 6a, 6c (glass plate adsorption tool 7
This is because it is extremely easy to set the position in the height direction of a, 7c). However, the present invention is not limited to this, and an appropriate means such as detecting one corner of the glass plate with a sensor and corresponding a glass plate adsorption supporting means (glass plate adsorption supporting tool) based on the detected corner can be adopted.

The glass plate adsorbing tool can be advanced and retracted to and from each piece by an advancing / retreating adjusting mechanism attached thereto, but when the glass plate adsorbing tool is pulled back and the glass plate is taken out, as described above, for example, the glass plate adsorbing and carrying means 6a. If the glass plate suction-supporting tool in (2) is slightly retracted and then the glass plate suction-supporting tools in the adjacent glass plate suction-supporting means are sequentially retracted, the blocking of the portion is easily released in sequence. Further, the pressing / tapping means can be operated during that time so as to knock.

After the glass plate G1 is once taken out, the interleaving paper adsorbing means 15 adsorbs the interleaving paper, and moves the robot arms respectively.
It is moved to a predetermined place by rotation and the next glass plate is taken out continuously, and these operations are the same as those proposed in Japanese Patent Application No. 3-106374 concerning the invention of the present applicant. .
