Abstract

PURPOSE:To restart immediately a normal operation with a handling device for recording medium when an electric supply is applied again after a service interruption, etc., by detecting the state of an arm member which supports a sucking head for the recording medium through an encoder. CONSTITUTION:A handling unit 1 consists of an arm unit 7 and a shift control mechanism 8 and shifts a floppy medium 3 and a separator 4 to an inspection unit 5 and then sends the medium 3 to a storing part C. An encoder is provided with an encoder plate 100 fixed to the shaft of the unit 7 and photodetecting elements 111a-115a and light emitting elements 111b-115b. When a current is supplied again after the service interruption, a sequence control circuit in a control unit 11 discriminates the specific state of the working sequence of the unit 7 from the states of the output signals S1-S5 of the elements 111a-115a. Thus the operations of a motor and the unit 5 are controlled and a normal working sequence is reset quickly.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for handling flat recording media such as floppy recording media (hereinafter abbreviated as floppy media), and particularly relates to a device for handling flat recording media such as floppy recording media (hereinafter abbreviated as floppy media), and in particular, The present invention relates to a recording medium handling device suitable for use in lifting up and transporting a bare recording medium before it is housed in a jacket or case.

[Prior art]

Conventional recording medium inspection devices for 51/4-inch mini floppies and 8-inch standard floppies are designed to handle floppy media housed in a partially open jacket.

[Intermediate points that the invention attempts to solve]

On the other hand, with the progress of office automation, the demand for small floppy media of 3.5 inches or less, called mini-floppies and micro-floppies, is rapidly increasing.

Media such as mini-floppies are often housed in plastic cases instead of conventional jackets, and in this case, it is preferable in terms of the manufacturing process to completely seal the case at the stage of storing it in the case.

Therefore, if such small floppy media are inspected while housed in a case as in the past, if the product fails, the entire product including the case must be discarded, and the cost must be kept low. In the case of mini-floppy media, this cannot be ignored.

Conventionally, if a semi-floppy disk failed an inspection, only that medium was discarded and its jacket or case was reused (for this reason, the jacket or case was not completely removed). (Inspections were conducted with part of the container open without being sealed.)

In addition, in conventional equipment that is inspected while housed in a jacket, the lead to/from the floppy medium for inspection is
Writing must be performed through the access window of the jacket, and it is not easy to adopt a method of shortening inspection time by using multiple heads to read/write the floppy medium at high speed. Therefore, recently,
Inspection of small 70-ply media such as microfloppies is becoming increasingly difficult for conventional inspection equipment to handle in terms of processing speed.

For this reason, it is considered desirable to inspect small floppy media such as microfloppies in a naked state without being housed in a jacket or case. However, conventional devices are not designed to handle bare floppy media, and if they were to be processed, problems such as damage to the floppy media may occur during handling.

[Purpose of the invention]

An object of the present invention is to relate to a recording medium handling device suitable for picking up a bare recording medium in a recording medium inspection unit, transferring it to an inspection section, and transferring the inspected recording medium to its storage section. .

[Means to solve problems]

A recording medium handling device according to the present invention includes: an arm member supported to be vertically movable and rotatable; a suction head supported by the arm member for suctioning and holding a recording medium;
Raise the arm member according to a predetermined operation sequence,
It consists of a mechanism for lowering, rotating, or stopping, an encoder plate that rotates together with the arm member, and a sensor combined with the encoder plate, and detects the state in which the arm member is in its operation sequence and determines the state. It is specially mandated to be equipped with an encoder that outputs a signal shown in FIG.

[Effect]

Since the recording medium is held by suction with a suction head, the recording medium is less likely to be scratched even when a bare recording medium is handled. In addition, since the state of the arm member is detected by an encoder, normal operation can be resumed immediately when the device is turned on, or when the power is turned on again after being turned off due to a power outage or emergency. Start the operation, or if the operation cannot be started, suspend the start of the operation to reliably prevent damage to the device or destruction of the recording medium.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing an example of a floppy recording medium inspection apparatus to which the present invention is applied. The handling unit 1 constitutes a recording medium handling device that is directly related to the present invention. This handling unit 1 picks up from a pallet 2 (referred to as a supply pallet) supplied to a predetermined supply position of a supply section A, floppy media 3 and separators 4 (second
(see Figures 3 and 3) are picked up one by one and transferred to the 7-4-Pie inspection unit 5, and only the floppy medium 3 is dropped onto the inspection unit 5. After that, the handling unit 1 again picks up the floppy medium 3 that has been inspected from the floppy inspection unit 5, transfers it to a specific storage position in the storage section C, and transports it to a specific storage position in the storage section C, and sets the pallet there (referred to as a storage pallet). Now, the inspected floppy medium 3 and separator 4 are stored in the storage pallet 61 set in the storage position.

Here, the storage pallets 6m, 6b, 6c, and 6d are placed on the stacker table 9, and by rotating the stacker table 9 by a predetermined amount (an integral multiple of 90 degrees), The storage pallet is set in the storage position. The storage pallets 6m, 6b, 6a, and 6d are transferred from the empty supply pallet 2 from the supply section and set on the stacker table 9. The four storage pallets 6, 6b, 6e, and 6d are respectively assigned to store floppy media that pass, top side fails, bottom side fails, and both sides fail.

In addition, the supply pallet 2 (storage pallets 6a, 6b, 6
As shown in FIG. 2 (Kl, (b)), the floppy media 3 and the separators 4 are stacked alternately and stored with the separators 4 on top.The opening of the separators 4 The inner diameter of 4& is the opening 3 of the floppy medium 3.
Larger than the inner diameter of a turtle. It should be noted that the floppy medium 3 referred to here is the bare floppy disk itself before being housed in a jacket or case.

One separator 4 and one medium 3, each with separator 4 facing upward, are adsorbed and held at the tip of suction head 10, which is evaporated onto handling unit 1, under negative pressure.

The handling unit 1 includes an arm unit 7 and a transfer control mechanism 8. The arm unit and door each support three suction heads 10 at 120 degree intervals in a loosely fitted state, with arms 7m and 7b, respectively. It has c. On the other hand, the transfer control mechanism 8 raises, lowers, rotates (120 degrees), or stops the arm unit 7 according to a fixed operation sequence. The transfer control mechanism 8, arm unit 7, and suction head 10 constitute the recording medium handling device of the present invention. The encoder associated with the arm unit is included in the transfer control mechanism 8.

The floppy inspection unit 5 is a so-called floppy disk drive device, and a drive motor spindle 51 is disposed above it. This spindle 5
The floppy medium 3 is set on top of the floppy medium 3, and a test is performed for predetermined recording characteristics. For this purpose, there are a total of six magnetic heads, for example, three for each side of the floppy medium.
For example, they are arranged at intervals of 120 degrees. Each magnetic head on each side is controlled to simultaneously read, write, or erase radially different areas of the floppy medium. Illustrations and explanations of mechanisms related to such a magnetic head will be omitted.

FIG. 3(a) is an overall sectional view of the suction head (head assembly) 10. Here, the state of the suction head 10 located at the supply pallet 2 or the storage pallet (6m, 6″b, 6a, 6dl) when the arm unit 7 has descended to the lowest position is shown. The suction head 10 has a generally triple cylindrical structure, and the outermost cylinder is the head part 1 for suctioning the separator 4.
01, and a suction port is opened on its tip surface.

The cylinder l on the inside is the head part 10b for suctioning the floppy medium 3, and is fitted into the outermost cylinder so that it can move up and down. There is. This head portion IQb is the tip portion F.
It consists of two blocks: and a rear main body R. An air passage (not shown) leading to the suction port passes through the boundary between the tip F and the rear body R, and can be opened when they are separated. Inside the head part 1ob,
A collet 10c for positioning the floppy medium 3 with respect to the spindle 51 is housed.

This collet 10c is rotatably supported via a bearing at the tip of a shaft 10d that is electrically distributed to the center of the head 10. The collet 10c has a tapered side surface. The shaft 104 is coupled to the rear body R via a built-in spring. The tip F is rotatable together with the collet 10c, and a spring is interposed between them. The window 16 is
Movable claw 17 provided on the arm (Fig. 3)
(see) is the opening into which it is inserted. A bottle 10e is provided protruding from the rear end portion (upper end portion in the figure) of the head portion 1ON, and a bottle 10f is similarly provided protruding from the rear end portion of the head portion 10m.

When the arm unit 7 is lowered to the lowest position, the suction head 10 located at the supply pallet lowers by its own weight to a position where its tip touches the separator 4 and the floppy medium 3 in the supply pallet 2, as shown in FIG. stand still in a state like a 凰). Suction head 10 located on the supply pallet
descends to a similar state and comes to rest. In this state, the height positions at which the supply pallet and the storage pallet are set are determined so that the bin 1Of is located above the rising arm, and the bin 10e is located above the rear end of the head section 101. ing. Further, in such a state, the bottle 10g provided on the shaft 10cl does not engage with the claw 17.

FIG. 3(b) is a schematic cross-sectional view showing a state in which the separator 4 and the floppy medium 3 are attracted and transferred by the suction head 1G. The head gtoa is held at a predetermined height position by a bin 10f provided thereon that engages with the upper surface of the arm.

On the other hand, the inner head portion 10b has a height such that the bottle 10e provided thereon engages with the rear end portion of the outer head portion 10m, and its tip is located a predetermined distance below the tip of the head portion 10m. Thus, the floppy medium 3 is held a predetermined distance below the separator 4, as shown.

The operation of dropping the floppy medium 3 held by the suction head 10 onto the spindle 51 and holding it on the spindle 51 will be described. When the arms 71, 7b, and 7c descend, the bar 15 extending from the head portion 101 of the suction head 10 that has reached that position engages with the stopper 14 provided only near the floppy inspection unit 5. , the rear main bodies R of the head portions 10m and 10b no longer descend (see FIG. 4(, )). When the arm further descends and the arms 7m, 7b, and 7c come down to the window 16, their claws 17 engage with the window 16 and the bottle on the φ axis 10d, as shown in FIG. 3 (el).

Reference is made to FIG. 4 below. As the arm descends further,
The shaft 10d is pushed down by the claw 17 against the force of the built-in spring, and at the same time, the tip F of the head portion 10b and the collet 10a descend. The tip F is separated from the rear main body R, and the suction port of the tip F becomes atmospheric pressure because the air passage is opened, and the floppy medium 3 adsorbed at the tip naturally falls onto the spindle 51. (Figure 4 Tbl
reference). As the arm further descends, the collet 10a further protrudes as shown in FIG. be aligned with the center of spindle 5&.

As the arm further descends, the collet 10c fits into the recess 5b of the spindle 51, as shown in FIG. So, floppy medium 3
is held under pressure. In this state, the tip F and the floppy medium 3 rotate following the spindle 5m.

Although the gap between the tip F and the rear body R is exaggerated in FIG. 4, the gap is actually extremely small, for example, about 2 mm.

In addition, the supply pallet 2 and the storage pallets 41° 4b, 4
c and 4d are located at approximately the same height, and the spindle 5a is located at a predetermined amount higher than that position. The supply section A and the storage section C are not provided with anything equivalent to the stopper 14.

Therefore, in that position, the head 10 is not prevented from descending, but descends together with the arm, and the claw 17
Therefore, the state shown in FIG. 3(1) is reached.

, 1 Note that 11 in FIG. 1 is a control unit that controls each mechanism of the inspection equipment housing, and the output signal of the encoder is input to the sequence control circuit of this control unit 11. 12 is a read/write control circuit section of a read/write head (not shown) in the inspection unit.

Next, the overall operation of the 70-piece recording medium inspection apparatus will be explained.

Now, the arm unit 7 is in an elevated position at an angle as shown in FIG. 1, and the floppy medium 3i to be inspected separator 4 is placed on the suction head 10 supported by the arm 7b as shown in FIG. 3 Tbl. It is adsorbed and held in the state of 1
- It is assumed that the floppy medium 3 and the separator 4, which have also been inspected, are held by suction on the suction head 10 supported by the frame 7C.

When the arm unit 7 is lowered by the transfer control mechanism 8, the suction heads 10 of the arms 7a and 7c descend without being hindered since there is no stopper 14, and are supported by the arms in a loosely fitted state. Therefore, regardless of the number of floppy media in the supply pallet 2 or the storage pallet, it stands still in the state shown in FIG. 3 (1F).In this way, the suction head is supported on the arm in a loosely fitted state. This absorbs the effects of variations in the number of floppy media on the supply pallet or storage pallet.

On the other hand, when the suction head 10 supported by the arm 7b descends to a certain height, the bar 15 engages with the stopper 14.
The head portion 1011 and the rear main body R of the head portion 10b cannot be lowered any further.

When the arm further descends, the pawl 17 engages the bottle 10g of the shaft 10d, as described in connection with FIG. 3(c), and the shaft 10d is pushed down, thereby By the above operation, 70 pieces of medium 3 fall from the suction head 10 onto the spindle 5a, are centered and set on the spindle 5a. After this,
Reading, writing, and erasing from the floppy medium 3 are performed at high speed by a total of six magnetic heads, and predetermined electrical characteristics related to recording are inspected.

When this inspection is completed, the head portion 10m of the suction head 10 of the arm 7C,
10b is switched from negative pressure to atmospheric pressure, the separator 4 and floppy medium (inspected) 3 that were held there are both released, and the storage pallet set in the storage position (
In the figure, they are stacked and stored in 61). Note that the rotation of the stacker table 9 is controlled in advance so that the storage pallet corresponding to the inspection result of the floppy medium is set at the storage position.

Further, when the test in the floppy test unit 5 is completed, the transfer control mechanism 8 operates in response to the completion signal to raise the arm unit 7 which is in the lowered state. Regarding the head 10 supported on the arm 7b, the claw 17
Since the pushing down of the shaft 10d is released, the shaft 10d is pulled up by the action of the built-in spring as the arm rises, and the collet 10c is separated from the spindle 51.

In addition, the tip F is pulled up by the action of the built-in spring between it and the collet loc, and is recombined with the rear body R.
Since the suction port becomes negative pressure again, the floppy medium 3 on the spindle 51 is suctioned and held by the head portion 10b. When the arm 7b further rises and the bottle 10f of the suction head engages with its upper surface, the suction head thereafter rises together with the arm, and finally reaches the state shown in FIG. 3 Tb).

In this way, the suction head 10 is configured to hold the picked up recording medium below the separator that was picked up at the same time, so the recording medium can be dropped and set on the spindle 5a without being obstructed by the separator. can. In addition, with a simple operation, the inspected recording medium can be attracted to the suction head 10, and the recording medium and the separator can be attached to the suction head 10 in the same positional relationship as immediately after being picked up.
It can be held at 0. Therefore, by lowering the suction pad 10 onto the storage pallet and then releasing the suction, the recording medium and the separator can be stored in a stacked state on the storage pallet.

Now, the suction head 10 supported by the arm 71 maintains the state shown in FIG. After reaching the separator 4, the suction head
Then, it rises together with the arm while adsorbing and holding the floppy medium 3, and finally reaches the state shown in FIG. 3(b).

After the arm unit 7 has risen to the highest position, the arm unit 7 is rotated 120 degrees in a predetermined direction (direction of arrow G in FIG. 1) by the transfer control mechanism 8, and the arm 7 is
a moves to the position of the floppy inspection unit 5, arm 7b moves to the storage position, and arm 7c moves to the supply position. During this rotation period, the control unit 11 controls the rotation of the stacker table 19 according to the inspection results, and the storage pallet corresponding to the inspection results is set at the storage position.

Below a, the arm unit 7 descends and the aircraft resumes operation.

In this way, this floppy recording medium inspection apparatus picks up, inspects, sorts, and stores floppy media in parallel, and can continuously and efficiently execute the floppy medium inspection process. Also, the floppy media may be scratched.
Be able to handle the transportation and other matters quickly. Since the floppy medium is in a bare state, if the medium uses a plastic case or jacket, such as a microfloppy, the rejected product will be the medium t! It is economical because all you have to do is to dispose of the case or jacket. Furthermore, since the floppy medium is handled in a bare state, the floppy inspection unit is equipped with multiple heads as mentioned above, and each head is assigned to a different area in the radial direction of the medium and can read/write and even erase at the same time. It is also easy to conduct the test and shorten the inspection time. This, combined with continuous processing, can greatly speed up inspection processing. Furthermore, since the sorting of accepted floppy media and rejected floppy media is done by selecting a storage pallet, the space required for sorting can be easily reduced compared to the conventional sorting by switching conveyance paths. The device can be made smaller accordingly, and floppy media are less likely to be damaged during sorting.

Next, the transfer control mechanism 8 will be explained with reference to FIG. In this figure, 32 is a shaft fixed to the center of the arm unit 7, and the lower end of this shaft 32 is rotatably supported by a bearing 36.

A gear 34 is inserted in the middle of the shaft 32. This gear 3
4 rotates integrally with the shaft 32, but with respect to the shaft 32,
It is movable along its length. 48 is a cam, and a motor 58 is connected to a bevel gear 54 fixed to a shaft 52 of the cam.
A bevel gear 56 fixed to the rotating shaft is meshed with the rotating shaft. Therefore, when the motor 58 is activated, the cam 48 rotates. A Geneva gear 46 is provided adjacent to the cam 48. The Geneva gear 46 has six pairs of teeth 46a provided at equal angular intervals, and the lower surface of the cam 48 has pins 5 that intermittently engage with each pair of teeth 46a of the Geneva gear 46.
0 is provided protrudingly. A cam 48 including this bin 50;
The Geneva gear 46 constitutes a Geneva mechanism (intermittent rotation drive mechanism). A gear 42 that meshes with the gear 34 is fixed to a shaft 44 inserted into the Geneva gear 46. cam 48
When the gear 46 rotates once, the Geneva gear 46 rotates 60 degrees.

Gears 42.34 double the amount of rotation of shaft 44 and rotate shaft 32.
It has a speed increasing effect that is transmitted to However, motor 5
8, the arm unit 7 rotates intermittently by 120 degrees as described above. Here, since the Geneva gear 46 engages with the pin 50 only during a part of one rotation period of the cam 48, it is less likely to cause interference compared to the -i type gear mechanism.

Reference numeral 38 denotes a lever that can swing up and down about the support shaft 40, and is disposed on both sides of the shaft 32 (only one is shown in the figure). The bearing 36 is connected to a pair of levers 38
is supported via a connecting rod 37 at the tip. Lever 3
A connecting rod 68 inserted into a portion near the tip of the lever 8 is supported by the tip of another lever 62 via a connecting member 66.

This lever 62 can swing up and down about a support shaft 60, and a cam pin 64 that engages with a cam groove 49 carved in the side surface of the cam 48 is provided near the base end of the lever 62. There is. When the cam 48 rotates, the lever 62 swings up and down according to the cam groove 49, and this swing causes the lever 38 to rotate.
is amplified and transmitted, and the arm unit 7 moves up and down. That is, the mechanism including the lever 38.62 and the cam 48 constitutes a mechanism for moving the arm unit 7 up and down. Here, the cam groove 49 is determined in accordance with the relationship between the rotation and up/down movement of the arm unit as described above. The swinging motion of the lever 62 is determined by the cam groove 49. Therefore, the rotation and vertical movement of the arm unit 7 are completely synchronized.

Now, the movement control mechanism 8 is provided with an encoder for detecting the state of the arm unit 7. As shown in FIG. 6, this encoder includes a disc-shaped encoder plate 100 and a photodetector element 111 such as a phototransistor.
a~115m, and light emitting element 1 such as a light emitting diode
From 11b to 115b.

As shown in FIG. 5, the encoder plate 100 is fixed to the shaft 32 of the arm unit 7 at a specific angle with respect to each arm 7-7C, and rotates and moves up and down integrally with the arm unit 7. . This encoder plate 100 is punched out of a thin metal plate, for example, and has three notches 101 and elongated holes 102 to 3 for each arm, as shown in FIG.
One each of one round hole 104 and one round hole 105 are formed at predetermined positions.

Photodetecting elements 1111 to 1151 and light emitting elements 111b to 1
Each pair of 15b constitutes an optical sensor associated with a notch, elongated hole, or round hole of the encoder plate 100, and is positioned with appropriate support means as shown in FIG. It is supported by a bearing 36 of an intervening shaft 32. The photodetecting elements 111a to 115a have corresponding light emitting elements 111b to 115 depending on the rotation angle of the encoder plate 100.
Light from b is selectively incident. Therefore, a certain relationship is established between the states of these output signals 51 to S5 and the state of the arm unit 7 in the operation sequence. In other words, the position and size of the cutout hole in the encoder plate 100 is determined so that the state of the arm unit in its operation sequence can be identified from the states of the output signals S1 to S5. The output signals 51-55 are input to the sequence control circuit in the control unit 11 as binary status codes. Note that the driving of the motor 58 is handled by this sequence control circuit.

Now, let us consider a case where, for example, a power outage occurs while the floppy recording medium inspection apparatus is in operation, and then the power is turned on again. The sequence control circuit in the control unit 11 recognizes the operating state at that time based on the state code (31 to S5) from the encoder, and depending on the state, the sequence control circuit controls the drive source of the motor 58 and other mechanisms, and also controls the drive source of the floppy drive. The operation of the inspection unit 5 can be appropriately controlled and the normal operation sequence can be quickly returned. If the operation is restarted, it may cause destruction of the floppy medium, destruction of other mechanical parts, abnormality in the inspection process, etc. (If there is a risk, the sequence control circuit will issue an alarm and take measures such as suspending the start of the operation.) Take.

In this way, since the encoder that detects the state of the arm unit 7 is provided, the state of the arm unit 7 can be recognized and used even when the power is turned on again after a power outage, without backing up the device power with a battery. Be able to reliably control the operation of the equipment.

In the embodiment described above, the suction heads are arranged at intervals of 120 degrees, but the invention is not limited thereto. The number of suction heads may also be changed as appropriate.

Further, the support mechanism of the suction head can also be changed as appropriate. Although the floppy medium suction head portion is locked to the separator suction head portion to determine the mutual height relationship, the floppy medium suction head portion may be directly locked to the arm. In addition, the suction position of the floppy medium is not limited to the vicinity of the center hole, but if the suction position is selected near the center type, the suction head can be designed compactly as described above, and the vicinity of the center hole of the floppy medium can be It has many advantages, such as being a part that is not used for recording and not having to be subject to strict conditions against scratches. Further, the suction head may have a shape other than the cylindrical shape a.

Furthermore, the head section for suctioning floppy media is divided into a tip section and a rear main body, and the negative pressure at the suction port is released by dividing the two sections, but the negative pressure state can also be controlled by other appropriate methods. good. However, the configuration in the embodiment can control the negative pressure state at the same time as the lifting and lowering of the tip and the collet, so the mechanism can be simplified, and the operation can be stabilized.
The control can be facilitated.

Furthermore, the mechanism for intermittently rotating the arm unit and the mechanism for moving it up and down can also be changed as appropriate.

However, the above configuration has the advantage that the arm unit can be rotated and moved up and down by a common drive source (motor), and the entire mechanism is simple and can be easily miniaturized.

Further, instead of the optical sensor of the above embodiment, a sensor that electrically or electrostatically detects the cutout hole may be used. Alternatively, an encoder plate having a shading pattern printed on a transparent plate may be used, and the shading pattern may be detected by an optical sensor.

Furthermore, the shape of the encoder plate is also arbitrary.

Note that the present invention can be similarly applied to applications that handle other planar recording media such as optical discs. Also, this invention (
It is also applicable to a device for handling recording media housed in a jacket or case.

Furthermore, it goes without saying that the recording medium handling device of the present invention can be used for purposes other than recording medium inspection devices.

〔Effect of the invention〕

The recording medium handling device according to the present invention raises, lowers, rotates, or stops an arm member supporting a suction head that attracts a recording medium according to a predetermined sequence of operations, and the arm member supports a suction head that suctions a recording medium, and raises, lowers, rotates, or stops the arm member at any time during the sequence of operations. The encoder detects whether the state is
Even if you handle bare recording media, the recording media will not be easily scratched.
In addition, even if the device power is not backed up by a battery, normal operation may start immediately or the device may not be able to start operating when the device is turned on or when the power is turned on again after being turned off due to a power outage or emergency. In such a situation, it is necessary to suspend the start of operation to reliably prevent malfunction or destruction of the device and destruction of the recording medium. can meet the conditions as follows. By using the recording medium handling device of the present invention, it is possible to easily realize a device for inspecting bare recording media.
