Abstract

PURPOSE:To surely perform pickup of one sheet by setting one unsealed side of a jacket at right angles to a traveling direction, laminating it in a stocker setting the position at a rear side, and providing a supporting roller, a toothed rubber roller, an ejecting roller, and a tearing roller at a lower part. CONSTITUTION:One unsealed side of the jacket 2 is set at right angles to the traveling direction, and it is laminated in the stocker 3 setting the position at the rear side, and the supporting roller 7, the toothed rubber roller 8 to send an unsealed disk at the lowest position to the outside, the ejecting roller 9 which forms a gap almost equivalent to the thickness of the sealed part of the jacket 2, and the tearing roller 10 are provided. The ejecting roller 9 is rotated synchronously with the toothed rubber roller 8 in the same direction, and a tearing roller 10 is rotated in a reverse direction. Since the toothed rubber roller 8 is stuck closely on the jacket 2 and an appropriate frictional force is generated, a sending force is not changed even in the lapse of time. Also, when the sheet is ejected accompanied by the second sheet and after, it is blocked by the reverse rotation of the tearing roller 10. In such a way, it is possible to surely pick up one sheet.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is directed to a floppy disk inspection device.
This invention relates to a method for separating and taking out unsealed floppy disks stacked in a stocker.

[Prior Art] Flexible floppy disks, which have recently been widely used as information recording media in various fields, are enclosed in paper jackets, and during media inspection at the manufacturing stage, it is difficult to detect whether the jacket is unsealed or not. It may be performed in a barking state (hereinafter simply referred to as an unsealed jacket or an unsealed disc). In this case, the unsealed disks stacked in the stocker are taken out one by one starting from the one at the bottom and inspected.

FIG. 2 shows the concept of a conventional ejecting mechanism for ejecting unsealed discs from a stocker.

The floppy disk 1 is inserted into a square jacket 2, and the three sides 2a, 2b, and 2c of the jacket are sealed.
Place the unsealed part 2d on the remaining side in the direction shown in the figure and place it in the stocker 3.
are laminated on. A conveyance mechanism consisting of a belt 5 and a pulley 6 that drives the belt is provided at the bottom of the stocker, and the belt contacts the F side of the jacket 2, sending out the lowest layer of the stack and discharging it in the direction of arrow A. do. In this case, a knife 4a is provided at the lower end of the partition plate 4 to cut off one disk so that two disks are not taken along with other disks located above.

[Problems to be Solved] The above-described ejection mechanism has several problems. Second
In the figure, since the unsealed part 2d is parallel to the disk feeding direction 2d is thin, and therefore a gap is created in the unsealed part with respect to the knife blade 4a, resulting in incomplete cutting and two pieces being removed. In order to avoid this, it is possible to tilt the knife, but this adjustment is surprisingly difficult. In addition, the surface of the belt 5 is worn out due to deterioration over time, resulting in a weak removal force and an unreliable ability to take out one sheet.

This invention provides an unsealed system that ensures one-sheet removal by dividing υF the disadvantage of incomplete cutting due to the directionality of the unsealed portion or unreliable one-sheet removal due to age-related deterioration of the belt. The purpose of this invention is to provide a separate and ejecting method for floppy disks.

[Means for Solving the Problems] The present invention is a method for separating and taking out unsealed floppy disks one by one, which are inserted into a jacket whose three outer sides are sealed and the other side is unsealed. The jackets are stacked on a stocker with one unsealed side perpendicular to the feeding direction and with that position at the rear, and a support roller for supporting the stack and a bottom of the stack are placed near the center of the bottom of the stocker. Each is provided with a toothed rubber roller for outwardly discharging the unsealed discs in position. In addition, an exit roller and a scraping roller are respectively provided on the lower and upper sides of the stocker exit, with a gap approximately equal to the thickness of the sealing dz portion of the jacket. The lower discharge roller rotates synchronously in the same direction as the toothed rubber roller, and the second scraping roller rotates in the opposite direction to the discharge roller.

In the second mechanism, the toothed rubber roller that feeds out the unsealed disk at the lowest position is in close contact with the jacket and generates an appropriate frictional force, so the feeding force does not change over time. At this time, even if Yu is taken out after the second photo,
It is blocked by the next rotation of the scraping roller in the opposite direction,
Only one unsealed disk at the lowest position is worn out and ejected by the ejection roller.

[Embodiment] FIG. 1 shows a structural diagram of an embodiment of a method for separating and taking out an unsealed floppy disk according to the present invention.

In the figure, the jackets 2 into which the floppy disks have been inserted are stacked in the stocker 3 so that the unsealed portions 2d are at right angles to the X direction of feeding and are at the rear. Two support rollers 7 for supporting the jacket on the instep and two toothed rubber rollers 8 for contacting the jacket and sending it out by rotation are arranged in the do part of the stocker. The rollers 7.8 are arranged in a balanced manner on both sides of the center hole 2e of the jacket to support the jacket at four points. next,
A discharge roller 9 is provided below the outlet of the stocker, and two scraping rollers 10 are provided above the discharge roller 9 with a gap approximately equal to the thickness of the sealing part 2a of the jacket. The toothed rubber roller 8 and discharge roller 9 are gears or pulleys! 1 to rotate synchronously in the same direction. The scraping roller 10 is rotated in the opposite direction. −[1
The rollers shown are connected by shafts 7a+8a+9a+ and IOa, respectively. Note that the partition plate 4 of the conventional mechanism explained in FIG. 2 may be provided if necessary, but the knife 4a is unnecessary.

To explain the operation of the above configuration, the support roller 7
The jacket 2 is stably supported by the toothed rubber roller 8, and by rotation of the toothed rubber roller, the unsealed disk of the lowest jacket in the stack is sent out in the direction of arrow A, and is ejected outward by the ejection roller. . Here, if the second and subsequent jackets are taken out, they will be blocked by the scraping roller rotating in the opposite direction, and only the lowest one will be ejected. be.

As is clear from the explanation in ``Effects of the Invention'', the unsealed floppy disk separation and removal method according to the present invention has the following features:
Since the unsealed part of the jacket is stacked on the stocker with the unsealed part perpendicular to the feeding direction, the thickness of the sealed part of the jacket in that direction is uniform, and by placing the unsealed part at the rear, the lowest position of the jacket One sheet passes stably through the gap between the scraping roller and the discharge roller and is ejected, ensuring that one sheet is taken. In addition, the toothed rubber roller used for the feed drive, regardless of the material of the jacket,
In addition, it does not deteriorate over time, and the jacket can be sent out stably by always changing the appropriate frictional force, so it can be applied to inspection equipment for unsealed floppy disks, and has a great effect in ensuring reliable separation and removal.
