Abstract

PURPOSE:To provide suction transport of only the uppermost one of the stacked sheet-formed disks, whose center holes are penetrated by a vertical shaft, by heaving them afloat through blowing of a gas to one of the sides of the stack, creating there an air layer, and thereby preventing double feed of disks. CONSTITUTION:The uppermost one of the sheet-formed disks stacked on a vertical motion table 3 fitted on a vertical shaft 2 is moved by a motor 6 to be actuated by a location sensor 7, and controlled into a certain specified level. Air is jetted from a longitudinal slitted jet 8 provided in a blowoff member 4 to cause heaving one of the disk sides afloat, and there an air layer is formed to provide inclined state. The inclined disk 1 is attracted by air holes 9 and transported, wherein the holes are bored in the suction surface of a transport member 5 and serve the suction in two separate systems. In the case of a floppy disk, for ex., having a thickness of 80mum and an outside dia. of 10cm, only the uppermost disk 1 is attracted with a gap of 0-5mm interposed.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Industrial Application Field The present invention mainly relates to a transport device for disks on sheets such as floppy disks, and in particular, a transport device in which a stack of disks is taken out one by one from the top. Regarding equipment.

B. Prior Art and Problems As a device for taking out stacked sheet-like disks in order from the top, the present inventor has developed a device that sucks the top surface of the disks with air and pulls them up one by one.

However, with this device, when the top surface of the uppermost disk is suctioned and pulled up, two disks may be suctioned together. This is because when members with mirror-like surfaces are brought into close contact, the air on the pressing surface is exhausted and attracted, and if the disk is made of a material that is easily charged with static electricity, it is attracted by static electricity. It is difficult to reliably peel and transport each disc one by one, and especially when the speed of pulling up the disc is fast, there is a drawback that multiple discs are transported at the same time.

The present inventor proposed a method in which air is blown toward the disks from the side parallel to the disks while the disks are suctioned and pulled up together, and the lower suction disks are separated by the air. developed. However, this method has the disadvantage that it takes time to separate the disks and does not improve processing capacity, since air is blown toward the disks after the transfer member attracts the disks and pulls them up.

In particular, the longer the air injection time was made to reduce multiple transfers of disks, the lower the processing efficiency became.

The present inventor has developed a method for solving the problem of multiple transfer of disks by blowing air from the side toward the stacked disks to create an air layer between the stacked disks. However, even if an air layer is provided in the stacked disks,
When the top surface was pressed to attract the uppermost disk, the air between the stacked disks was easily expelled, and the disks were attracted again, making it impossible to eliminate multiple transfers.

The present inventor has further developed the invention with the aim of solving this drawback, and an important purpose of the present invention is to inject gas from the side toward the stacked disks, and also to , a unique configuration in which the topmost disk is adsorbed while remaining in a gas floating state, which greatly reduces the number of multiple transfers of disks and significantly shortens the processing time for transferring a single disk. We are in the process of providing equipment.

C0 Means for Solving Conventional Problems The stacked disks with the center hole inserted through the vertical shaft are blown with gas from the side by a gas blowing member to form a gas layer on at least one side between the stacked disks. is formed and maintained in a gas floating state.

The transfer member does not press strongly against the upper surface of the disk.
While floating in air, the upper surface of the disk is attracted, pulled up, and transferred to the next process.

01 Actions and Effects In the Mi layer state, at least one side of the disk is held in a gas floating state, and its upper surface is attracted to the transfer member and pulled up. Even if the disks are separated from the next disk due to the gas layer and some of them are in contact with each other, the upper disk is pulled up, allowing air to flow smoothly between the disks, and the lower disk is attracted to the upper disk. This will greatly reduce the number of things that can happen.

In the device of the present invention, after the transfer member adsorbs the disks, the adhering disks are not peeled off, but the adsorption of the disks is released when the disks are stacked, so the transfer member simply adsorbs the upper ends of the disks and transfers them. If possible, the delay in processing time due to the separation of multiple adsorbed discs can be eliminated and the transfer time per disc can be minimized.

In addition to the faster processing time, since air is blown onto the disks in a stacked state, it is possible to blow air onto the disks for a long time, ensuring that each disk can be separated, and minimizing the probability of multiple transfers. Features that can reduce the amount of energy used are also realized.

Furthermore, since the uppermost disk is not adsorbed by the lower end disk and tends to float in a gaseous state and easily peel off, the transfer member can easily and quickly and reliably adsorb the uppermost disk. Ru.

E. Preferred embodiment Embodiments of the present invention will be described below based on the drawings.

The device for taking out stacked sheet-like disks shown in FIG. A blowing member 4 that sprays the disc 1, and a transfer member 5 that sequentially takes out the disc 1 from the top.

Even if the disks l are taken out sequentially from the top, the upper and lower stands 3
so that the top disk l is always located on the same plane.
That is, it is mounted on a base so that it can move up and down, and is moved up and down by the motor 6 so that it rises as the disk I is taken out.

The motor 6 is controlled by a position sensor 7 for the disk l, and when the disk l is taken out by the transfer member 5, the motor 6 is driven to control the vertical position of the uppermost disk l to be constant.

The air blowing member 4 is provided on the side surface of the disk l so as to blow air horizontally toward the stacked disks l.
Air is blown onto the disk 1 through an air blowing hole 8 in the form of a vertically long slit, which is arranged to extend somewhat from the outer periphery of the disk 1.

As shown in FIG. 1, in the case where the blowing member 4 is disposed only on one side of the disk 1 and blows air from one side, one side of the disk 1 is floated by air and an air layer is provided on one side. The disk 1 is slightly tilted. In this configuration, one side of the disks 1 is brought into contact with each other and air is injected between the disks 1, so that the air blown between the disks does not pass through and the rear part of the disk can be efficiently floated with air. Therefore, a portion of the disk 1 can be efficiently floated with a small amount of air blowing out.

When the inclined disk l is attracted to the transfer member 5,
Air flows into the space between the disks from the floating portion and is attracted to the transfer member 5 in a horizontal position.

However, in the present invention, the position of the blowing member 4 is not limited to one side of the disk 1, and it is also possible to blow air onto the disk 1 from both sides to float the disk 1 as a whole.

When the number of stacked disks I is small, the blowing member 4 injects air all over the stacked disks from top to bottom. just,
When a large number of disks are stacked, air may be injected only to the upper disks.

The amount of air injected from the blowing member 4 can be controlled by the size of the air blowing hole 80 and the air pressure supplied thereto. The ideal amount of air to be blown is when the disk 1 floats in the air and stands still. In the inventor's experiments, when the disk is a floppy disk with a thickness of 80 microns and a diameter of approximately 10 cm, the blowing member is In the state shown in Fig. 1, in which the air blowing hole 8 is installed on one side, the optimal condition is that the total length of the air outlet 8, that is, the vertical length, is 30 mm, the width is 0.1 mm, and the supply air pressure is 2 to 3 kg/crn2. Ta. However, if the disk is heavy, it is better to increase the amount of air blown out to float the disk.

The blowing member 4 can use almost any gas instead of air, such as nitrogen or carbon dioxide.

When the blowing member 4 injects air, the blowing member 4 is connected to a compressor, and when injecting nitrogen or carbon dioxide gas, the blowing member 4 is connected to a gas cylinder.

The gas injected from the blowing member 4 is preferably passed through a filter or the like (not shown) to remove dust.

As the transfer member 5, any member that can attract the upper surface of the stacked disks 1, lift them up from the vertical shaft 2, and transfer them to the next step can be used. The transfer member 6 in FIG. 1 has an air hole 9 opened in the suction surface at the lower end for adsorbing the disk with air, and this air hole 9 is connected to the air suction means 11 via a hose lσ. .

A plurality of air holes 9 are opened so that the disk l can be reliably adsorbed, and the plurality of air holes 9 are divided into two series, and the two divided series of air holes 9 are independently and It is connected to air suction means 11.

The lowering position of the transfer means 5 during suction is set so that the disk 1 can be suctioned while floating in the air, that is, so that the disk 1 is not pushed down strongly from above to exhaust air from the disk 1riff and are not brought into close contact with the disk 1. According to experiments conducted by the present inventor, when the disk is a floppy disk with a thickness of 80 microns and an outer diameter of 10 cm, the distance between the upper surface of the air-floated disk and the lower surface of the transfer member is, for example, 0 to 10 mm, preferably 0 to 10 mm. It was possible to reliably adsorb it with a diameter of 5 mm.

The present invention is not limited to floppy disks, and can be used to transport all sheet-like disks.

If the disk is made of magnetic metal, an electromagnet can also be used for the transfer member 5.

When using an electromagnet, if the structure is such that the attracted disk magnetically shorts the NS pole of the electromagnet to form an open magnetic path, as shown in Figure 2, the magnetic path will flow from the top disk to the bottom disk. The magnetic flux leakage can be reduced, and the magnetic attraction force can prevent the lower disk from being attracted together.

F0 Usage state of the device The center hole of the disk 1 is inserted into the vertical shaft 2, and the required number of disks 1, for example, several hundred to several thousand disks, are stacked on the upper and lower stands. In this state, the blowing member 4 blows air from the side over the top or the entire disk 1, forming an air layer between the disks and causing the disk 1 to float in the air. The transfer member 5 contacts or approaches the upper surface of the uppermost disk, attracts it, and pulls it up.

At this time, air is flowed throughout the space between the disks to prevent the upper and lower disks from adhering to each other, and the uppermost disk 1 is separated from the lower disk and pulled up by the transfer member. When one disk is removed and the top surface position of the stacked disks falls, the vertical table 3 moves up and adjusts the top surface position of the disk 1 to the desired position.This operation is then repeated, one disk at a time. The sheet will be taken out securely.

By the way, in FIG. 1, the lowering position of the transfer member 5 is kept constant by gradually raising the upper and lower table 3 having the vertical shaft 2, but the lowering position of the transfer member 5, which is the disk suction position, is adjusted depending on the number of disks to be taken out. If the structure is such that as the disk is taken out, the suction position of the transfer member 5 is lowered by the thickness of the disk, it is not necessarily necessary to raise the upper and lower tables 3. However, in this case, the blowing member 4 needs to be lowered in accordance with the number of stacked disks so as to blow air at least above the upper portions of the stacked disks.
