Description

  The present invention relates to a disk processing apparatus, and more particularly to an apparatus having a stocker rack having a plurality of stockers capable of stacking and storing a plurality of information recording disks. The present invention relates to an improvement in a disk processing apparatus capable of performing movement control.

  In recent years, information recording discs such as CD-R, CD-RW, DVD-R, and DVD-RW have been widely used as digital information storage media. Since these information recording discs are relatively inexpensive and easy to carry and distribute, they are effective for distributing digital information. For example, it is used not only for mass-production general sales, but also for recording digital information for advertisements and samples of companies and products, and for creating labels for indie music. On such a distribution information recording disk, digital information is written and a label is printed on the surface of the information recording disk in order to display the information content of the disk.

  In general, DVDs containing music CDs and movies are mass-produced using large-scale equipment, but cost is reduced. However, in the case of small-scale production of several hundred pieces as described above, large equipment Is not suitable considering the equipment cost and running cost. In view of this, there has been proposed a portable type disk processing apparatus equipped with a digital information recording unit, a label printing unit, a disk transport unit, and the like having the same functions as a large-scale facility (see, for example, Patent Document 1). .

  In the apparatus disclosed in Patent Document 1 described above, a stocker (unprocessed information recording disk on the left side and processed information recording disk on the right side) that stacks and stores a plurality of information recording disks on the left and right sides of the front side of the apparatus is disposed, A recording unit such as a CD-R writer and an arbitrary printing unit such as an ink jet type, a thermal transfer type, and a sublimation type are stacked in a central portion on the back side. Each of the recording unit and the printing unit has a disc tray that can freely move back and forth, and is configured to come to a position between the left and right stockers arranged on the front side when the disc tray advances to the eject position. Further, a guide rail is formed so as to cross the left and right stockers and the advanced disk tray, and the disk transport device (unit) can be moved along the guide rail.

  In this way, during the process of writing data to the information recording disk and label printing, the left and right stockers can insert and remove the information recording disk, and are performed as necessary, so that the production status can be grasped. For this purpose, it is necessary to know the quantity of information recording disks in the stocker. Normally, stockers are equipped with sensors that detect when the stocker is “empty” and when it is “full”, but since detailed quantity detection has not been performed, There was always a need to check the quantity. As an apparatus for confirming the quantity in the stocker, for example, there is a printer apparatus. Such a printer apparatus has a sensor that always optically recognizes the remaining amount of paper in the stocker or predicts based on the weight (for example, Patent Document 2).

JP 2003-331479 A JP 2001-114451 A

  The storage capacity of the information recording disk of a stocker mounted on a portable type device as shown in Patent Document 1 is generally about 50, and although it is a small-scale production, there are frequent cases where the production exceeds the stocker capacity. To do. In this case, it is necessary to load and unload the stocker a plurality of times in order to add an unprocessed information recording disk and to remove a processed information recording disk. In this case, it becomes difficult to grasp the production amount, and the work becomes complicated and the production efficiency decreases. For this reason, for example, a plurality of unprocessed and processed stockers are mounted, and using a stocker rack that moves a desired stocker to an arbitrary position, the moved information recording disk is picked up and transported by a disk transport device, and a predetermined stocker is used. It is conceivable to perform processing. In this case, it is possible to reload a large number of information recording disks at a time, reducing the number of times the stocker is taken in and out, and improving the production efficiency. On the other hand, however, the quantity of information recording disks of individual stockers varies greatly, and management of the information recording disks of the individual stockers becomes complicated. Even when the quantity in each stocker is recognized using the technique of Patent Document 2, the stocker of the information recording disk is taken out and stored, and the unprocessed information recording disk is added or ejected after processing. Therefore, the management of the quantity of each stocker becomes complicated, and the quantity balance of the information recording disks among the stockers tends to be lost. If the balance between stockers is lost, it may cause abnormal noise or vibration during movement of the stockers, or cause wear or damage to mechanical parts. Therefore, the operator must individually instruct removal from the stocker before processing and storage in the stocker after processing based on the recognized quantity in the stocker so that the balance between stockers is not lost. There is a problem that handling of the recording disk becomes more complicated.

  Therefore, the present invention, in an apparatus having a stocker rack having a plurality of stockers capable of stacking and storing a plurality of information recording disks, makes it possible to select an optimal stocker while easily recognizing the number of information recording disks of each stocker, It is an object of the present invention to provide a disk processing apparatus capable of smoothly moving a stocker rack and managing an information recording disk.

  The disk processing apparatus of the present invention includes a processing means for performing predetermined processing on an information recording disk, a pre-processing stocker capable of storing a plurality of information recording disks before processing, and a plurality of information recording disks after processing. At least one stocker for storing at least one of post-processing stockers that can be stored and at least one stocker rack capable of moving a predetermined stocker to an arbitrary position, and information before processing from the stocker for processing by the processing means Quantity detection for detecting the quantity of information recording disks stored in each stocker mounted on the stocker, and a disk transport means for taking out the recording disk and transporting the processed information recording disk for storage in the stocker And the balance of movement of the stocker rack based on the number of information recording disks in each stocker. Characterized in that it comprises a selection control means for information selection retrieval stocker and / or storage stocker of the recording disk for causing Joka, a.

  Here, the processing means is, for example, a recording unit for writing digital data on an information recording disk, a printing unit for printing a label on a non-recording surface of the information recording disk, or the like. As the recording unit, for example, a CD-R writer, a CD-RW writer, a DVD-R writer, a DVD-RW writer, or the like is used. As the printing unit, for example, an ink jet type, a thermal transfer type, a sublimation type or the like is adopted. be able to.

  According to this configuration, the quantity management of the information recording disks of each stocker can be easily performed, and the stocker selection for stabilizing the movement balance of the stocker rack is automatically performed, so that the disk processing apparatus can be driven stably. It can be performed.

  Further, the disk processing apparatus according to the present invention has the above-described configuration, wherein the stocker rack includes a rotation mechanism that rotatably arranges a plurality of stockers and moves a predetermined stocker to a predetermined position. Is characterized by detecting the quantity of information recording disks stored in each stocker during the rotational movement.

  According to this configuration, by rotating the stocker rack at least once, the single quantity detection unit can sequentially detect the quantity for a plurality of stockers.

  In the disk processing apparatus according to the present invention, in the above configuration, the quantity detection unit includes an optical sensor that irradiates the label surface of the information recording disk with light and performs distance measurement based on reflected light from the label surface. It is characterized by that.

  According to this configuration, it is possible to accurately detect the number of information recording disks in a non-contact manner by an easy and inexpensive means.

  In the disk processing apparatus of the present invention having the above-described configuration, the quantity detection unit performs a measurement operation on the information recording disk at a plurality of points, and the information recording stored in the corresponding stocker based on the average value. It is characterized by detecting the number of disks.

  According to this configuration, even when the light reflection state on the label surface of the information recording disk is partially unsatisfactory, the quantity measurement can be stably performed. Further, by performing the measurement operation at a plurality of points, it is possible to detect the inclination of the information recording disk.

  In the disk processing apparatus according to the present invention, in the above configuration, the quantity detection unit detects an initial quantity of information recording disks of each stocker when the stocker rack is loaded in the apparatus or when the apparatus power supply is activated. The selection control means recognizes the quantity of information recording disks of each stocker being processed based on the movement state from the initial quantity, and selects the stocker.

  According to this configuration, the number of times of information recording disk quantity detection can be minimized, and the processing speed of the entire apparatus can be improved.

  In the disk processing apparatus according to the present invention, the processing unit includes a printing unit that performs label printing on at least a label surface of the information recording disk, and the quantity detection unit prints at least the printing unit printing. Each data has a correction value for correcting a detection value of reflected light of the optical sensor.

  It is desirable to perform label printing on the information recording disc for each content of the information recording disc in order to indicate the data recording content. In addition, in order to obtain a distinction from the information recording disc before processing, arbitrary printing may be performed merely in a design sense. However, depending on the printing contents, the light from the optical sensor causes irregular reflection or the reflectance is lowered, so that the reflection state differs individually. As a result, it may not be possible to obtain sufficient reflected light for accurate quantity detection. Further, when the number of information recording disks before and after printing is to be detected, the reflection state is greatly different, so that it is necessary to provide a dedicated optical sensor for tuning.

  By the way, when printing by the printing means is finished and the information recording discs stored in the stocker are sequentially rotated and moved by the stocker rack and measurement is performed by the optical sensor, the measurement position by the optical sensor is recorded regardless of the printing content. It becomes a certain position (area) on the disc. Therefore, by preparing a correction value according to the print content, it is possible to accurately detect the quantity by correcting the received reflected light based on the correction value. Even in the case of non-printing, the state of the label surface varies depending on the type of the information recording disc, and the reflection state may change. Usually, the change is within the detection allowable range of the optical sensor, but a correction value for each type of information recording disk may be prepared as necessary.

  According to this configuration, it is possible to accurately detect the number of information recording discs regardless of the print contents and to perform a good stocker selection. Further, it is not necessary to tune the optical sensor according to the contents of printing.

  Also, the disk processing apparatus of the present invention is characterized in that, in the above configuration, the optical sensor surrounds the light projecting portion with a cylindrical member having a predetermined length to form spot light.

  According to this configuration, the light emitted from the optical sensor can be spotted, more accurate distance measurement can be performed, and accurate quantity detection can be easily performed.

  Further, the disk processing apparatus of the present invention, in the above configuration, includes a pre-processing stocker rack capable of mounting a plurality of pre-processing stockers and a post-processing stocker rack capable of mounting a plurality of post-processing stockers. It is characterized by.

  Stocker racks before processing are only reduced in number of information recording disks, and stocker racks after processing are only increased. Therefore, it is easy to balance storage amounts of stockers on individual stocker racks.

  Hereinafter, embodiments of the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

  FIG. 1 is a perspective view illustrating a schematic configuration of a disk processing apparatus 10 according to the present embodiment. FIG. 1 shows a state in which an upper surface cover on the upper surface is removed from the housing 12 and a partition wall that divides the interior into an upper layer portion and a lower layer portion is removed for explanation of the internal configuration. FIG. 1 shows a state in which an optional part 14 is attached, as will be described later. Further, FIG. 2 shows a schematic top view of FIG.

  As shown in FIGS. 1 and 2, the disk processing apparatus 10 has processing means for performing predetermined processing in the apparatus. Specifically, a recording unit for writing desired digital data on an unprocessed information recording disk (for example, CD-R, CD-RW, DVD-R, DVD-RW, etc.) or an information recording disk after data writing is completed. The non-recording surface includes a printing unit or the like that prints characters, symbols, diagrams, or the like corresponding to or not corresponding to the recorded contents. In the case of FIG. 1, as the recording unit 16, two CD-R writers are arranged in the upper right part on the apparatus rear side, and as the printing unit 18, for example, a thermal transfer type printer is arranged in the upper left part on the apparatus rear side. The configuration of the two recording units 16 requires more time for data writing than the printing. Therefore, the configuration of the two recording units 16 improves the operating efficiency of the printing unit 18 and the disk processing apparatus 10. This is to improve the overall operation efficiency. Of course, the number of recording units 16 and printing units 18 mounted is arbitrary.

  In addition, a disk transport device 20 for supplying and discharging information recording disks to and from the recording unit 16 and the printing unit 18 is disposed at the upper part on the front side of the disk processing apparatus 10. As will be described later, the disk transport device 20 has a guide rail 22 extending in the left-right direction of the disk processing device 10, and a carriage 24 is driven by a drive mechanism such as a motor and a drive belt along the guide rail 22. It can be moved arbitrarily. The carriage 24 is mounted with a substantially panda graph type clamper arm that expands and contracts in the downward direction of the apparatus, for example. Of course, the structure of the clamper arm is also arbitrary, and other than the panda graph type, a carriage type that moves along a guide rail extending in the vertical direction of the apparatus may be used.

  Further, a stocker rack 30 in which a plurality of stockers 28 in which a plurality of information recording disks 26 are stacked and stored is mounted on the lower layer of the upper layer of the apparatus in which the recording unit 16, the printing unit 18, the guide rail 22 and the like are arranged. Is arranged. The stocker rack 30 has a motor 32 as a rotational drive source at a substantially central portion, and can move a desired stocker 28 within an operation range of a clamper arm supported by the carriage 24. As shown in FIG. 2, in the stocker rack 30, an unprocessed stocker 28a for storing an unprocessed (data not written and label unprinted) information recording disk 26, processed (data written and label printed) is stored. A processing stocker 28b for storing the information recording disk 26 and a processing error stocker 28c for storing the error (data writing failure or label printing failure) information recording disk 26 are mounted. In addition, each stocker 28a-28c is freely detachable with respect to the stocker rack 30, and the number and arrangement position of each stocker can be changed according to a use.

  In this embodiment, as described above, stocker racks are added as optional parts 14. In this case, for example, all the stockers of the upper stocker rack 30 shown in FIG. 2 are used as the unprocessed stocker 28a, and the stocker 28b for processing and the stocker 28c for processing error are mounted on the stocker rack added by the optional part 14. can do. In this case, since the clamper arm of the disk transport device 20 needs to be able to access the upper and lower stocker racks, an access opening 34 is formed in a part of the upper stocker rack 30 as shown in FIG. A clamper arm that clamps the information recording disk 26 can freely pass through the access opening 34. As described above, when the stocker rack 30 is composed of one unit, as shown in FIG. 2, the stockers 28 a and 28 b are arranged at opposing positions, and the access opening 34 has an opposing position at the opposing position. It is preferable to arrange the stocker 28c.

  In FIGS. 1 and 2, the illustration is omitted for the purpose of explaining the internal structure, but the upper layer of the apparatus in which the recording unit 16, the printing unit 18, the guide rail 22, etc. are arranged, and the stocker rack 30 Between the lower layer portion disposed, a recording unit 16 and a printing unit 18 are placed, and a partition for ensuring the strength of the entire disk processing apparatus 10 is formed. Therefore, an access opening similar to the access opening 34 formed in the stocker rack 30 is formed in the partition wall.

  FIG. 3 shows an example of a configuration block diagram of the disk processing apparatus 10.

  The disk processing apparatus 10 is mainly configured by a main CPU 36 that mainly controls the recording unit 16 and the printing unit 18 described above, and a robot control CPU 38 that mainly performs drive control of the disk transport device 20 and the stocker rack 30. . The main CPU 36 is connected to a storage unit (for example, HDD) 40 that stores digital data to be written on the information recording disk 26, label image data, and other various data. Although not shown, an input unit for performing various operations, a display unit for displaying an operation state and an operation state, and the like are connected. Note that a dedicated or general-purpose external computer (external PC) 42 is connected to the disk processing apparatus 10 of the present embodiment, and recording and printing are performed while processing digital data and label image data to be written on the information recording disk 26. To do. In this case, the main CPU 36, the HDD 40, the input unit, the display unit, and the like described above may be omitted and all functions may be provided on the external PC side. Of course, the function of the robot control CPU 38 may also be performed on the external PC 42 side.

  The robot control CPU 38 interconnected with the main CPU 36 includes an arm motor 44 for expanding and contracting the clamper arm, a carriage motor 46 for moving the carriage 24 of the disk transport device 20, a rack motor 48 for rotating the stocker rack 30, and the like. Is connected. The robot control CPU 38 also detects whether the carriage 24 (arm) has moved during the clamping operation by the clamper arm, and whether the stocker rack 30 has moved during the clamping operation by the clamper arm. Rack sensor 52 for detecting the disk, and a disk detection sensor for detecting whether or not the information recording disk 26 exists when the clamper arm attempts to perform a clamping operation, or whether or not the tip of the clamper arm contacts the information recording disk 26 54, a remaining amount sensor 56 for detecting the remaining amount of the information recording disk of each stocker 28a to 28c is connected. As these sensors, optical sensors, mechanical limit sensors, and the like can be used. The remaining amount sensor 56 can also be configured by a weight sensor or the like provided on the lower surfaces of the stockers 28a to 28c. The arm sensor 50, the rack sensor 52, and the like also perform position detection regarding whether or not the stocker rack 30 or the carriage 24 has moved to a predetermined clamping operation position, and the carriage motor 46 and the rack motor 48 are feedback-controlled. So that the signal is supplied. In the configuration of FIG. 3, the robot control CPU 38 is connected to a display unit (for example, LCD) 58 for displaying the amount of information recording disks of each stocker 28 and displaying the operation state of each drive unit. Of course, it may be displayed on the external PC 42 side.

  FIG. 4 shows a state in which the door 59 is opened and the stocker rack 30 is pulled out in order to load an unprocessed information recording disk 26 in the disk processing apparatus 10 or to remove a processed or error information recording disk 26. It is shown. The stocker rack 30 can be pulled out when the disk transport device 20 is not in operation, and the information recording disk 26 can be arbitrarily loaded and unloaded. The disk processing apparatus 10 checks the quantity of the information recording disks 26 of the stockers 28a to 28c by using the remaining amount sensor 56 every time the stocker rack 30 is pulled out and stored and the door 59 is closed.

  The remaining amount sensor 56 is attached to, for example, a part of the inner wall of the housing 12 or the ceiling surface of the partition wall, and recognizes the quantity of the information recording disk 26 for each stocker by rotating the stocker rack 30 once. By this recognition, even if an unprocessed information recording disk 26 is added or a processed information recording disk 26 is taken out during a series of disk processing operations, the total number of processes can be accurately managed. Further, by recognizing the amount of the information recording disk 26 stacked on the stocker every time the door 59 is closed, the amount of fluctuation of the information recording disk 26 of each stocker 28a to 28c while the door 59 is closed is also determined. It is possible to accurately grasp, and it is possible to accurately control the extension of the clamper arm described later.

  FIG. 5 shows a perspective view of the stocker rack 30 alone. As described above, the stocker rack 30 is provided with a freely rotatable motor 32 (decelerated to a predetermined speed by a gear train or the like) at the center. A rotating cap 32 a having a flange around it is connected to the rotating shaft of the motor 32. A plurality of pins are formed on the flange portion, and the stockers 28a to 28c are rotated by a predetermined amount in synchronization with the rotation of the motor 32 by engaging with the engagement holes formed in the stockers 28a to 28c. . Each stocker 28 a to 28 c moves on the base plate 30 b along a circular recess 30 a formed in the stocker rack 30. Therefore, it is preferable that rollers or the like are appropriately formed on the back surfaces of the stockers 28a to 28c. Further, each stocker 28a to 28c needs to stop at a predetermined position where the information recording disk 26 is clamped and released by the clamper arm, so that it needs to perform an intermittent operation at a predetermined angle (60 ° in FIG. 5). There is. Therefore, it is preferable that a rotation moderation mechanism or the like is provided so that it can be stopped at every predetermined angle.

  FIG. 5 shows a state in which the access opening 34 is opened to access the stocker rack of the optional part 14. Of course, the stocker 28 can be attached to that portion, and six stockers 28 are provided. Can also be used. Conversely, it is also possible to use the required number of stockers 28 (for example, three).

  FIG. 6A shows a perspective view of a stocker 28a for stacking and storing unprocessed information recording disks 26, and FIG. 6B shows stacking and storing of information recording disks 26 for processed or processing errors. A perspective view of the stocker 28b (28c) is shown. As is clear from FIGS. 6A and 6B, the stocker 28a and the stocker 28b (28c) only use the guide pin 60a and the guide pin 60b for supporting the information recording disk 26 in a stacked manner. Is used. Therefore, a plurality of guide pin standing holes 64 are formed in the base 62.

  In the case of the unprocessed stocker 28a shown in FIG. 6A, the outer diameter portion of the information recording disk 26 is supported by the thin guide pin 60a. In FIG. 6A, four guide pins 60a are erected as an example, but if three or more, the information recording disk 26 can be favorably supported, and the number is arbitrarily selected. be able to. By supporting the outer periphery of the information recording disk 26, the tip end of the clamper arm can be inserted into the clamp opening 26a (see FIG. 5) formed in the center of the information recording disk 26 to support the clamp. It becomes possible.

  On the other hand, in the case of the processed or error stocker 28b (28c) shown in FIG. 6B, a large-diameter guide pin 60b is stacked and accommodated by being inserted into the clamp opening 26a in the center of the information recording disk 26. ing. In the case of a processed or error information recording disk 26, the clamp opening 26a of the information recording disk 26 is easily inserted into the guide pin 60b by opening the clamper arm clamp in the vicinity of the tip of the guide pin 60b. In addition, the information recording disk 26 can be stably supported.

  In addition to the position of the guide pin 60a shown in FIG. 6A, a guide pin standing hole 64 is formed in the base 62. This is because, for example, it corresponds to an information recording disk other than a 12 cm circular disk such as an 8 cm circular disk or a square disk. Further, on the side surface of the base 62, a ball 66 that can be moved forward and backward by a spring or the like that constitutes the rotational moderation mechanism of the stocker 28 is disposed. The ball 66 is engaged with a recess formed on the inner surface of the circular recess 30a of the stocker rack 30, so that a good sense of moderation can be obtained.

  FIG. 7 shows details of the carriage 24 of the disk transport device 20 and the clamper arm 68 mounted on the carriage 24.

  The carriage 24 has a substantially box shape with an open lower surface, and the upper surface is slidably engaged with a guide rail 22 provided in the housing 12 of the disk processing apparatus 10. The disk transport device 20 has a motor (not shown) as a drive source, and transmits the driving force of the motor to the carriage 24 via a transmission mechanism such as a drive belt. Accordingly, the carriage 24 moves in the horizontal direction in the drawing along the guide rail 22 in accordance with the driving amount of the motor.

  On the other hand, the clamper arm 68 has a panda graph structure that opens and closes in a “substantially square shape” by a link mechanism having a clamper 72 supported by a clamper holder 70 at the tip. The link mechanism includes a first link 74 having fan-shaped gears 74a and 74b at both ends, a second link 76 having a fan-shaped gear 76a at one end and the other end rotatably connected to the clamper holder 70, and a first link 76. A link plate 78 that maintains engagement between the sector gear 74b of the link 74 and the sector gear 76a of the second link 76, a first auxiliary link 80 that operates in parallel with the first link 74, and a first that operates in parallel with the second link 76. 2 auxiliary links 82. The 1st link 74, the 2nd link 76, the 1st auxiliary link 80, and the 2nd auxiliary link 82 are engaged so that rotation is possible, respectively. For example, one end of the first link 74 and the first auxiliary link 80 is pivotally supported on the inner wall surface of the carriage 24, and the other end is pivotally supported on the link plate 78. Further, one end of the second link 76 and the second auxiliary link 82 is rotatably supported on the link plate 78, and the other end is rotatably supported on the clamper holder 70.

  When a motor (not shown) rotates, the drive gear 84 rotates in the counterclockwise direction, for example, and the sector gear 74a of the first link 74 rotates in the clockwise direction. As a result, the first link 74 rotates in the clockwise direction. At this time, since the sector gear 76a of the second link 76 is engaged with the sector gear 74b of the first link 74, the second link 76 is rotated in the counterclockwise direction. As the rotational movement of the first and second links 74 and 76 proceeds, the first and second links 74 and 76 open in a “substantially square shape” as shown by broken lines in FIG. Is lowered in a substantially vertical direction. At this time, due to the presence of the first and second auxiliary links 80 and 82, the clamper holder 70 can be moved up and down without tilting. Further, the first and second auxiliary links 80 and 82 contribute to the improvement of link rigidity and realize a smooth operation. In FIG. 7, the position indicated by the solid line is the state in which the clamper arm 68 is retracted to the home position, and the position indicated by the broken line is extended to clamp the information recording disk 26 stored in the unprocessed stocker 28a. It is in a state (as an example, a state in which the information recording disk 26 stored at the bottom is clamped).

  Further, the clamper arm 68 can be stopped at an arbitrary height according to the rotational driving amount of the motor. Therefore, in FIG. 7, the disk tray 16a of the recording unit indicated by the two-dot chain line is stopped at an optimum height, and the information recording disk 26 can be smoothly supplied and discharged. 7 shows a partition wall 86 that separates the upper layer portion and the lower layer portion, which are not shown in FIGS. The partition wall 86 is formed with an opening 86a through which the information recording disk 26 clamped by the clamper arm 68 can be passed.

  FIG. 8 shows the detailed structure of the clamper 72 supported by the clamper holder 70. 8A is a top view of the clamper 72, FIG. 8B is a side view (hatching is given importance to distinguishing each member), and FIG. 8C is a view of the clamper holder 70. It is explanatory drawing explaining the relationship with the clamper 72. FIG. The clamper 72 is arbitrary as long as it clamps by performing a pressing operation on the information recording disk 26. However, in the present embodiment, a head portion having an engaging element (for example, a sphere) that can move forward and backward. A description will be given by taking as an example a configuration in which the recording medium is inserted into the clamping opening 26a of the information recording disk 26.

  As shown in FIGS. 8A and 8B, the clamper 72 includes a clamper body 90 having a clamper head 88 at a substantially central portion, and a clamper body 90 sliding in the vertical direction as shown in FIG. A clamper holder 70 (only a part of which is shown) is movably supported. Sliding pins 90 a (for example, two on each side) are erected on the side wall of the clamper body 90 and engaged with a long slot 70 a formed in the clamper holder 70. An urging means (not shown) (not shown) is arranged between the clamper body 90 and the clamper holder 70, and always urges the clamper body 90 downward. Then, as shown in FIG. 7, the clamper arm 68 extends and the clamper body 90 (clamper 72) contacts the information recording disk 26, so that the clamper body 90 moves upward. That is, a damper mechanism is formed to absorb an impact generated when the clamper arm 68 and the information recording disk 26 come into contact with each other, and the information recording disk 26 can be smoothly pressed and clamped by the clamper arm 68.

  A disc detection sensor 54 (for example, an optical sensor) that detects the presence or absence of the information recording disc 26 is arranged inside the clamper body 90, and whether or not the information recording disc 26 exists in the facing stocker 28a or the like, and the clamper body Whether or not 90 and the information recording disk 26 are in contact with each other is detected. Further, a clamper movement sensor 96 (for example, an optical sensor) is disposed inside the clamper body 90. The clamper movement sensor 96 detects whether or not the clamper body 90 has contacted the information recording disk 26 and the clamper body 90 has moved a predetermined amount depending on whether or not the shielding plate 70b formed on the clamper holder 70 has blocked the sensor. Yes. Based on this detection result and the detection result of the disk detection sensor 54, it is determined whether or not the clamping operation has been completed. Of course, a determination based on one of the results is also possible.

  As shown in FIGS. 8A and 8B, a slider 98 that moves in the left-right direction in FIG. 8A as a result of the clamper body 90 being moved upward by the information recording disk 26 inside the clamper body 90. A self-holding solenoid 100 that holds the moved slider 98 is disposed. Also, a crank arm 102 that operates according to the movement of the slider 98, a cam 104 that rotates by the crank arm 102, a chucking ball 106 that moves forward and backward to clamp the information recording disk 26 (in this embodiment, for example, 3), a coil spring 108 for returning the slider 98, a coil spring 110 for preloading the cam 104, and the like are arranged.

  The operation of the clamper 72 configured as described above will be described. As shown in FIG. 7, when the clamper arm 68 extends and the clamper body 90 comes into contact with the information recording disk 26 and further presses, the clamper body 90 moves in the direction of arrow A in FIG. Here, a cam 98 a having an inclined surface is erected on the slider 98, and a leaf spring 70 c is fixed to the clamper holder 70. Accordingly, as the clamper body 90 moves in the direction of arrow A, the leaf spring 70c contacts the cam 98a and moves the slider 98 in the direction of arrow B.

  As shown in FIG. 8A, since the crank arm 102 is rotatably engaged with the slider 98 via the joining pin 98b, the crank arm 102 is moved along with the movement of the slider 98 in the arrow B direction. Rotates around the point O in the direction of arrow C. Further, since the crank arm 102 is engaged with the cam 104 via the joining pin 104a, the cam 104 rotates in the direction of arrow D in FIG. As the cam 104 rotates, the slope 104b of the cam 104 pushes the chucking ball 106 outward (in the direction of arrow E) of the clamper head 88. At this time, the information recording disk 26 is in close contact with the clamper body 90 and is positioned above the chucking ball 106 as shown in FIG. 8B. The information recording disk 26 is clamped between the lower surface of the clamper body 90 supported from the side. Since the coil spring 110 is disposed between the slider 98 and the crank arm 102 and the cam 104 applies a load, the urging state of the chucking ball 106 by the cam 104 is maintained, and the information recording disk 26 is stabilized. Retention can be performed.

  Simultaneously with the pushing operation of the series of chucking balls 106 as described above, the slider 98 moves against the biasing force of the coil spring 108 by the magnetic force of the self-holding solenoid 100 connected to the tip of the slider 98. And the clamped state of the information recording disk 26 is maintained.

  On the other hand, when the clamper arm 68 moves to the position of the disk tray 16a or the processed stocker 28b with the information recording disk 26 clamped, it is necessary to release the clamp of the information recording disk 26. In this embodiment, the magnetic force is released by applying a predetermined voltage to the solenoid 100. As a result, the slider 98 moves in the direction opposite to the arrow B by the urging force of the return coil spring 108, and accordingly, the crank arm 102 and the cam 104 also rotate in the anti-C direction and the anti-D direction. That is, the urging force of the cam 104 with respect to the chucking ball 106 disappears, and the chucking ball 106 can freely move. As a result, the information recording disk 26 can be detached from the clamper head 88 due to its own weight, and land on the disk tray 16a or the processed stocker 28b.

  In the disk processing apparatus 10 configured as described above, in order to drive the stocker rack 30 smoothly, it is necessary to take out and store the information recording disk 26 in a well-balanced manner so that it does not rotate eccentrically. When the balance between taking out and storing the information recording disk 26 is lost, the stocker rack 30 rotates, causing vibrations and abnormal noises, and causing unnecessary loads on the motor 32 and other mechanical parts to cause wear and damage. It also becomes. Therefore, in the present embodiment, the quantity of the information recording disks 26 stored in the stockers 28a to 28c is accurately recognized, and the information recording disks 26 are taken out from the appropriate stocker 28a based on the remaining number, Control which suppresses that the above-mentioned balance is lost by storing in the stocker 28b (28c) is performed.

  As described above, the robot control CPU 38 is connected to the remaining amount sensor 56 for detecting the quantity of the information recording disks 26 of the stockers 28a to 28c. The remaining amount sensor 56 functions as a quantity detecting means for detecting the quantity of the information recording disk 26 together with the main CPU 36. As shown in FIG. 9, the remaining amount sensor 56 is an optical sensor disposed on a partition wall 86 (see FIG. 7) immediately above the stocker 28 that moves on the door 59 side of the disk processing apparatus 10. Light and light are received. As described above, since the stocker rack 30 has a configuration that can be rotated by the motor 32, the information recording disk 26 accommodated on the stockers 28a to 28c can detect a certain label surface by rotating. The position 112 (hatched position) passes through the position directly below the remaining amount sensor 56.

  As shown in FIG. 10, the remaining amount sensor 56 includes a light projecting unit 56a and a light receiving unit 56b, and a triangulation that includes a cylindrical guide member 56c for converting the light emitted from the light projecting unit 56a into spot light. This is a distance measuring sensor capable of. By narrowing the light emitted from the light projecting portion 56a using the guide member 56c, even if irregular reflection occurs on the label surface of the information recording disk 26, the influence is minimized and the detection error is suppressed. Yes. Further, as described above, various printings are performed on the label surface of the information recording disk 26, and the reflectance of reflected light varies depending on the printing contents. By narrowing down the spot diameter, this variation in reflectance can be minimized. The spot diameter can be adjusted according to the length of the guide member 56c. This adjustment is performed both when the information recording disk 26 is fully loaded in the stocker 28 and when it is empty. It is desirable to adjust to a state where appropriate good sensitivity can be obtained.

  The reflected light emitted from the light projecting unit 56a and reflected by the label surface 26b of the information recording disk 26 and received by the light receiving unit 56b is A / D converted and supplied as an output level a to the main CPU 36 via the robot control CPU 38. Is done. On the other hand, the main CPU 36 detects the output level b detected by the remaining amount sensor 56 and the information recording disk 26 when the stocker 28 stored in advance in the HDD 40 or a separately provided storage unit is empty. By reading the output level c and calculating | a−b | / c, the quantity (remaining amount) of the information recording disk 26 of the stocker 28 currently being measured can be detected.

  It is sufficient to calculate the quantity of the information recording disk 26 once for each stocker 28. However, as described above, the state of the surface of the information recording disk 26 (the state of the substrate before label printing and the printing after printing). The reflection state varies depending on the content state. Therefore, distance measurement is performed a plurality of times at the detection position 112 shown in FIG. 9, and when the variation of each measurement value is within the allowable range, the quantity calculation of the current information recording disk 26 of the stocker 28 is performed based on the average value. It is desirable. Of course, when there are extremely different measurement values due to irregular reflection or the like, the calculation is performed with the values ignored.

  In addition, when a foreign object is caught between the information recording disks 26 stacked and stored in the stocker 28, or when the information recording disk 26 is caught by the guide pins 60a, 60b, etc. In some cases, the stocker 28 is held obliquely. In addition, the stocker 28 itself may be set obliquely due to the insertion of foreign matter or the like. Since the thickness of the information recording disk 26 is generally around 1.2 mm, accurate quantity recognition cannot be performed in the case of detecting the quantity once per stocker and when the information recording disk 26 is tilted. On the other hand, when the measurement is performed at a plurality of points, when the information recording disk 26 is tilted, the measured values change sequentially, so that the tilt of the information recording disk 26 can be easily detected. Error messages can be output easily and quickly. That is, it can contribute to prevention of erroneous recognition.

  As shown in FIG. 9, in the stocker rack 30, an unprocessed stocker 28a is disposed at an opposing position, and a processed stocker 28b is disposed at another opposing position. Therefore, the robot control CPU 38 takes out the information recording disk 26 so that the difference in the quantity of the information recording disks 26 of the opposite stocker 28 is reduced based on the quantity of the information recording disks 26 accommodated in each stocker 28. The stocker 28a for performing storage and the stocker 28b for performing storage are selected. For example, in FIG. 9, the stocker 28a with the largest quantity of the unprocessed information recording disk 26 is selected in the first quantity detection. For example, the information recording disk 26 is removed from the stocker 28a in the 12 o'clock direction. After the predetermined processing is completed, the processed information recording disk 26 is stored in the stocker 28b having the smallest quantity, for example, the stocker 28b in the 8 o'clock direction. Next, when the stocker 28a having the largest number of unprocessed information recording disks 26 is, for example, the stocker 28a in the 6 o'clock direction, the information recording disk 26 is taken out from the stocker 28a. After the predetermined processing is completed, in the case of the stocker 28b having the smallest quantity, for example, the stocker 28b in the 2 o'clock direction, the processed information recording disk 26 is stored in the stocker 28b. By repeatedly performing the same selection process, the selection is performed so that the difference in the storage quantity between the opposing stockers 28 is always minimized. As a result, when the stocker rack 30 is driven to rotate, the stocker rack 30 always shifts in the direction in which the rotation balance is improved, so that vibration and noise can be generated, and the load on each member can be suppressed.

  In the case where the selection is made and the stored quantity of the opposing stocker 28a is equal, the quantity balance between the adjacent stocker 28b and the opposing stocker 28b is referred to and the adjacent stocker 28b is adjacent to the larger stocker 28b. The stocker 28a is taken out, and selection is made so that the stocker rack 30 as a whole is balanced. When selecting storage, based on the same concept, the storage is performed in the stocker 28b adjacent to the stocker 28a on the smaller quantity side.

  The overall operation of the disk processing apparatus 10 including the selection process of the stocker 28 as described above will be described based on the flowchart of FIG.

  First, the main CPU 36 determines whether or not the disk processing apparatus 10 is powered on (S100). Subsequently, it is determined whether or not the door 59 is closed (S101). When the door 59 is opened, this means that the stocker rack 30 may be pulled out and the unprocessed or processed information recording disk 26 may be taken in and out, and the stocker rack 30 may not be set. To do. This determination can be easily made by a sensor (for example, a mechanical sensor) provided on the door 59 or the like.

  When the door 59 is closed in step (S101), the main CPU instructs the robot control CPU 38 to detect the quantity of the information recording disk 26 of each stocker 28. The robot control CPU 38 controls the remaining amount sensor 56. In addition to being activated (may be always active), the rack motor 48 is used to rotate the stocker rack 30 at least once. That is, during the rotation operation of the stocker rack 30, the quantity of the information recording disk 26 is detected for each stocker 28 at the detection position 112 shown in FIG. 9 (S102). Therefore, every time the power is turned on, the number of information recording disks 26 is always detected. When the quantity detection is completed for each stocker 28 (S103), after confirming again whether the door 59 has been opened or closed (S104), as described above, the unprocessed state of taking out the information recording disk 26 is not performed. The stocker 28a is selected (S105), and the robot control CPU 38 drives the rack motor 48 (S106), and further drives the carriage motor 46, the arm motor 44, and the like from the selected stocker 28a using the clamper arm 68. One information recording disk 26 is taken out (S107). At this time, the robot control CPU 38 performs feedback control of the arm motor 44, the carriage motor 46, the rack motor 48, and the like based on signals from the arm sensor 50, the rack sensor 52, the disk detection sensor 54, and the like.

  The taken out information recording disk 26 is supplied to the recording unit 16 and the printing unit 18 and subjected to predetermined disk processing (S108). For example, predetermined digital data writing processing is performed by the recording unit 16, and label surface printing processing is performed by the printing unit 18. Of course, the processing for the information recording disk 26 is arbitrary, and printing may be performed first, or either data writing processing or printing processing may be performed.

  When the processing for the information recording disk 26 is completed, the robot control CPU 38 checks whether or not the door 59 has been opened and closed during the disk processing (S109). During the disk processing, the door 59 is opened, and an unprocessed information recording disk 26 can be added to the stocker rack 30 and a processed or error information recording disk 26 can be taken out. This is because the total amount of can vary. If the door 59 is opened and closed, the robot control CPU 38 performs steps (S110) and (S111) after the closing operation of the door 59, detects the quantity in each stocker again, and then performs the processing. The stocker 28b for storing the information recording disk 26 is selected based on the quantity status of each stocker 28 (S112). That is, the quantity detection is always performed when the stocker rack 30 is inserted into or removed from the disk processing apparatus 10.

  Of course, when the door 59 is not opened and closed, the total amount of the information recording disks 26 in the stocker rack 30 is constant, and the quantity of the information recording disks 26 in each stocker 28 is the initial value quantity detected in step (S102). Since the main CPU 36 can recognize the information recording disk 26 based on the moving state of the information recording disk 26, an appropriate stocker 28b can be immediately selected without re-detecting the quantity. That is, the rack motor 48 is driven (S113), and the selected stocker 28b is moved to the standby position of the clamper arm 68, so that the information recording disk 26 can be quickly stored (S114). In this way, the quantity detection of the information recording disk 26 in the disk processing apparatus 10 can always be accurately performed by always detecting the quantity of the information recording disk 26 when the stocker rack 30 is taken in and out. In addition, the number of times of quantity detection can be minimized, and the processing speed of the entire disk processing apparatus 10 can be improved.

  Thereafter, the main CPU 36 confirms whether or not the processing of the predetermined number of information recording disks 26 instructed initially is completed (S115). If the predetermined number of disk processing is not completed, the process proceeds to step (S104). Then, the above process is performed again. When a predetermined number of disk processes have been completed, a series of operations of the disk processing apparatus 10 is terminated, and the next process start command is awaited.

  In the flowchart shown in FIG. 11, the opening / closing confirmation of the door 59 is performed in step (S109) to increase the degree of freedom of loading and unloading of the information recording disk 26. However, the opening / closing of the door 59 is permitted. The conditions to be set can be set such as “when the clamper arm 68 is not operating” or “when there is no disk being processed”, and by restricting the opening and closing of the door 59, steps (S109) to (S111) can be omitted.

  By performing such processing, it is possible to smoothly perform selection control of the optimal stocker 28 in consideration of a balanced operation of the stocker rack 30, and the number of information recording disks 26 of each stocker 28 can be easily obtained. While grasping, it is possible to satisfactorily suppress vibration and abnormal noise during operation of the disk processing apparatus 10 and prevent wear and breakage of mechanical parts.

  By the way, when printing is performed on the label surface of the information recording disk 26, the reflected state of the light projected by the remaining amount sensor 56 varies depending on the printing content, and there may be a case where light reception for good distance measurement cannot be performed. Therefore, in the present embodiment, a correction value for correcting the detection value of the reflected light in accordance with the printing state of the label surface is prepared in advance, for example, in the HDD 40 or other storage unit for each print content. In the present embodiment, the printed information recording disk 26 taken out by the clamper arm 68 from the disk tray 18a of the printing unit 18 is always stored in the stocker 28b that has moved to the same clamp opening position. That is, if the information recording disk 26 has the same print contents, the same print portion always comes to the detection position 112 in FIG. Accordingly, the remaining amount sensor 56 can always perform a light receiving operation at a portion of the scheduled print content. That is, if the correction value of the detection value is set for each print content and the measurement value is corrected, the main CPU 36 can make a quantity determination based on a certain threshold value. For example, when the reflectance is poor depending on the print content, it is possible to perform a correction to increase the correction value and perform the same quantity determination as when good reflection is obtained, and suppress detection errors caused by the print content. be able to. Therefore, it is not necessary to tune the optical sensor according to the contents of printing, etc., and by setting an appropriate correction value, it is possible to use an inexpensive general-purpose sensor that does not have a very high detection accuracy, reducing costs and increasing design flexibility. It can also contribute to improvement.

  In the case of the unprinted information recording disk 26, the state of the base of the label surface differs depending on the type, and the reflection state may change. Usually, the change is within the detection allowable range of the optical sensor. If necessary, a correction value for each type of the information recording disk 26 is prepared, and the unprocessed information recording disk 26 stored in the stocker 28a is prepared. You may correct | amend a measured value.

  In the above-described embodiment, an example in which control is performed so that the stocker rack 30 is well balanced using one stocker rack 30 has been described. However, as shown in FIG. Racks can be added. In this case, all of the upper stocker racks 30 can be unprocessed stockers 28a, and the lower stocker racks 30 can be processed stockers 28b. Also in this case, when the information recording disk 26 is taken out, when the information recording disk 26 of the upper stocker 28a is taken out in order from the largest quantity (if all are the same quantity, from an arbitrary position) and stored, The storage processing is performed in order from the smallest number of the information recording disks 26 of the lower stocker 28b (if all are empty, from an arbitrary position). In this case, the supply of the unprocessed information recording disk 26 to the disk processing apparatus 10 and the discharge of the processed information recording disk 26 can be performed for each stocker rack, so that errors in and out of the information recording disk 26 are suppressed. And can contribute to the improvement of work efficiency.

  The upper stocker rack 30 is formed with an access opening 34 through which a clamper arm 68 for transporting the information recording disk 26 passes to the lower stocker rack. A stocker 28c can be arranged. Even when a processing error information recording disk 26 is generated, the occurrence rate is low, and even if it is stored at a position opposite to the access opening 34, the balance of the entire stocker rack 30 is not significantly affected. Of course, the stocker 28c may be mixed with the lower processed stocker 28b. In addition, when a plurality of types of information recording disks 26 having different printing contents are continuously produced, an error stocker 28c may be disposed at a position opposite to the stocker 28b that accommodates the information recording disk 26 with a small production amount. This is effective in balancing the rotation of the entire stocker rack.

  The structure shown in the present embodiment is an example, and a stocker and a process for detecting the quantity of the information recording disks 26 stored in the stocker 28 mounted on the stocker rack 30 and taking out the information recording disks 26 for disk processing. As long as the stocker for storing the information recording disk 26 after completion is appropriately selected and has a structure and control that can balance the drive of the stocker rack, the mechanism part of each figure, the configuration block of FIG. 3, and the flowchart of FIG. Etc. can be appropriately changed, and the same effects as those of the above-described embodiment can be obtained.

  Further, in the present embodiment, the case where the stocker rack 30 is rotationally driven has been described as an example. However, as long as the stocker rack is configured so that a plurality of stockers 28 are mounted and moved sequentially, the quantity detection is possible even for a linear movement type, for example. Therefore, it is possible to move the stocker rack in a balanced manner and to select an optimal stocker, and the same effects as in this embodiment can be obtained. Further, the quantity detection means is arbitrary as long as the quantity of the information recording disk 26 in the stocker can be detected. For example, the quantity detection means can also be used by using an ultrasonic wave, and the same effect as in the present embodiment can be obtained.
