Description

TECHNICAL FIELD The present invention relates to a method of reliably separating and picking up flexible works stacked in a container one by one even at high speed.

(Prior art and its problems) Generally, as a method of separating and taking out the flexible works stacked in the container, an air nozzle or the like is used to separate the works near the upper layer and a baffle plate or the like is provided in the process of taking out the works. There is a method of separating and taking out one by one.

However, in the case of flexible work such as a magnetic disk, which has a very smooth surface, air between the works is pushed out due to the self-weight of the stacked works, which causes a close contact. However, it is difficult to surely separate the sheets one by one.
Further, contact with the recording surface when taking it out like a magnetic disk may cause scratches and stains on the recording surface, and it may not be possible to write a recording signal. It was even more difficult to separate and take out.

Therefore, in view of the problems in the conventional method for separating and taking out the flexible work described above, the present invention can easily and surely separate the flexible works one by one to prevent the development of the lifting work. Provided is a method for separating and taking out a flexible work having excellent characteristics such that the work surface of the work can be taken out without being scratched or soiled, the assembly can be performed at high speed, and the facility cost can be reduced. That is the purpose.

(Summary of the Invention) In order to achieve the above-mentioned object, a method for separating and taking out flexible works of the present invention is a method for separating and taking out the flexible works stacked in a container one by one from above. Has a rotating shaft extending in the horizontal direction above the side of the flexible work, and while rotating in the direction facing the upper surface of the stacked flexible works about the rotating shaft, the flow rate is intermittently increased. At least one air valve capable of ejecting different air is provided, and the air is blown from the air valve to the end of the stacked flexible workpieces, and the stacking can be performed by a suction disc equipped with a bending mechanism. The uppermost flexible work of the flexible works is adsorbed, and the flexible work is bent into a mountain shape and taken out to further enhance the effect of separating the works one by one.

(Effects of the Invention) According to the method of the present invention, a flexible work is positively used between works by using an air valve provided with a special blowout hole pattern (discontinuous) and a suction plate that takes out the work while bending it into a chevron shape. The air can be sent in a reliable manner, and even at high speeds 1
It is possible to separate and take out one by one.

Further, according to the present invention, even if the portion that can come into contact when taking out is limited like a magnetic disk, according to the present invention, only the inner peripheral portion and the like can be easily bent into a chevron shape to obtain the effect of separating the sheets one by one. be able to.

(Examples) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a configuration in which the drive unit of the present invention is omitted, and FIG.
(A) and (B) are plan and front views of an embodiment of the present invention,
FIGS. 3 (A) to (C) are views showing the operation sequence of the separation and takeout of the present invention, and FIGS. 4 and 5 (A) and (B) are views of the configuration and the embodiment of the air valve of the present invention. is there.

As shown in FIG. 3 (A), flexible works 2 (such as magnetic disks) are stacked in a container 1 (not shown).
The vicinity of the upper layer is floated by the pair of air valves 6a and 6b. The rotation direction of the air valve is the direction facing the upper surface of the flexible work 2, that is, the direction in which the flexible work is blown down, as shown by the arrow in FIG. 3 (B).

Next, when the flexible work 2 on the uppermost surface is chucked by the suction board 3, the work 2 has a drive section (not shown).
Thus, the work 2a is bent as shown in FIG. 3 (B).

At this time, when two or more flexible workpieces 2 are in close contact with each other by being bent, a slight deviation occurs between the uppermost workpiece 2a and the next workpiece 2b due to the difference in the radius of curvature or the center of the arc. . In this state, the suction plate 3 rises, but the air valves 6a and 6b blow downward intermittently with different amounts of air, so that air penetrates between the work 2a and the work 2b, and is reliably separated one by one. It

The air valves 6a and 6b are preferably arranged above the uppermost surface of the flexible work 2. The structure of the air valve is such that the rotary nozzle 6 rotates around a fixed nozzle 7 extending in the horizontal direction as shown in FIG. 4 and has blowout holes which are discontinuous in the rotational direction.
The fixed nozzle 7 is arranged such that the rotary nozzle 6 and several blow-out holes 8 are always opposed to each other, and when the rotary nozzle 6 rotates, the fixed nozzle 7 is intermittent and has a different blow-out amount depending on the number of the blow-out holes facing each other. Is blown out.

The air valves 6a and 6b are rotary nozzles 6 as shown in FIG. 5 (B).
The fixed nozzle 7 and the fixed nozzle 7 may be reversed. Further, the pattern of the blowing holes may be any as long as the arrangement in the direction perpendicular to the rotation direction is not the same. It should be noted that one pair of air valves may be further provided at right angles.

As for the method of bending the means 3 for taking out the flexible work 2, any number of suction plates 3 may be used, and the bending operation may be performed separately. For example, the uppermost surface is chucked by a picked-up portion (here, the suction plate 3), and a fixed and flexible head is provided a little above, and the head is handed over to form a flexible state. In the present invention, the specific direction of bending does not matter, and it is important to surely bend in a chevron shape.

When the flexible work is separated and taken out by the above method, the work is bent and air easily enters between the works, and further, due to the intermittent and different amount of air blown out from the air valves 6a and 6b. Work pieces can be reliably separated and taken out one by one at high speed.
Further, since the flexible work need only be bent, it can be handled without touching an important part of the work.
