Description

  The present invention relates to a technique for protecting a movable part from vibration, impact, etc. during transportation of the apparatus by fixing the movable part included in the apparatus.

  An example of a technique related to a library apparatus is disclosed in Patent Document 1. The library apparatus of Patent Document 1 includes cartridge transport means, storage, and medium drive means. The hangar has a plurality of shelves divided in the vertical and horizontal directions on the front surface, and each shelf stores a cartridge containing a recording medium. The medium driving means is provided outside the storage and drives the recording medium of the inserted cartridge. The cartridge transport means transports and inserts the cartridge between the storage and the medium driving means. As a result of the above configuration, the library device of Patent Document 1 drives a recording medium selected from a plurality of recording media.

  However, the library apparatus of Patent Document 1 has a problem that cartridge transport means, which is a robot mechanism for transporting and inserting / removing cartridges, is vulnerable to vibration and impact during transport of the library apparatus.

  The library apparatus has movable parts such as an accessor and a picker. Therefore, when the library apparatus is transported, it is desirable to protect it from vibrations and shocks during transportation by fixing the movable parts to the housing of the library apparatus (transport lock state).

  An example of a technique for protecting a library apparatus from vibration and impact during transportation is disclosed in Patent Document 2. The disk reproducing device of Patent Document 2 includes a transport unit that moves within the device main body, and a transport unit fixing unit that protrudes from the device main body and prevents the transport unit from moving when the device main body engages with the packing material. Including. As a result of the above configuration, in the disc reproducing device of Patent Document 2, it is easy to fix the transport unit when the disc reproducing device is transported.

  However, the disc reproducing apparatus of Patent Document 2 has a problem that a dedicated packing material is required during transportation.

  Therefore, in general, it is desirable that the library apparatus itself has a transport lock mechanism that fixes movable parts such as an accessor and a picker. For example, in the library apparatus, before the transportation, when the power is turned off by software control, and when the accessor and the picker are in the sleep mode, the transportation lock mechanism is operated to bring the accessor and the picker into the transportation locked state. Is possible. Then, for example, in the library apparatus, when the power supply is turned on after transportation, the transportation lock mechanism is automatically released, so that the accessor and picker positioning that can occur when the accessor and picker are operated in the transportation locked state. It is possible to prevent inaccuracy and breakage of accuracy.

  An example of a technique in which the library apparatus itself has a transport lock mechanism is disclosed in Patent Document 3. The transport lock device of Patent Document 3 includes a lock member, a lock actuator, and a slot. The locking member is attached to the carriage so that it can move between a locked position and an unlocked position. The lock actuator cooperates with the lock member to move the lock member between the locked position and the unlocked position. The slot is provided in the frame and is dimensioned to engage the lock member when the carriage is in the stowed position and when the lock member is in the locked position. As a result of the above configuration, the transport lock device of Patent Document 3 protects the internal mechanism from destruction when transporting a data storage system that processes and stores data cartridges.

  In the picker transport lock mechanism of Patent Document 3, the picker transport lock mechanism is moved between the lock position and the unlock position by the operation of the picker (thum assembly) installed on the accessor. However, even when the picker is retracted to accommodate the cartridge, the picker transport lock mechanism is always moved to the locked position. That is, the number of operations of the picker transport lock mechanism is large. Therefore, there is a problem that the picker transport locking mechanism reaches the end of its life quickly. On the other hand, in order to prevent the picker transport lock mechanism from always being moved when the picker transport lock mechanism is retracted to accommodate the cartridge, it is necessary to enlarge the accessor. That is, there is a problem that the space for storing the data cartridge is reduced.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings, equivalent components are denoted by the same reference numerals, and description thereof is omitted as appropriate.
(First embodiment)
The first embodiment of the present invention, which is the basis of each embodiment of the present invention, will be described.

  A configuration in the present embodiment will be described.

  FIG. 1 is a block diagram showing an example of the configuration of the movable object moving device according to the first embodiment of the present invention.

  The movable object moving device 300 in the present embodiment includes a lock mechanism 100, a movable object 200, and a control unit 310.

  FIG. 2 is an exploded perspective view showing an example of the configuration of the locking mechanism according to the first embodiment of the present invention. 2 and the subsequent drawings, the width direction of the device (housing) is indicated by “Y”, the depth direction is indicated by “X”, and the height (thickness) direction as viewed from a certain direction. Is represented by “Z”. That is, the X direction, the Y direction, and the Z direction are substantially orthogonal to each other. In each of the Y direction, the X direction, and the Z direction, the right direction, the back direction, and the upward direction are referred to as “positive side”, and the left direction, the front direction, and the downward direction are referred to as “negative side”. In the drawings after FIG. 2 and the following description, the direction in which the apparatus is installed is an example, and the direction in which the apparatus is actually installed may be arbitrary. In the following description, the positive side in the X direction is the “X +” side, the negative side in the X direction is the “X−” side, the positive side in the Y direction is the “Y +” side, and the negative side in the Y direction is The “Y−” side, the positive side in the Z direction is also referred to as the “Z +” side, and the negative side in the Z direction is also referred to as the “Z−” side.

  The movable object 200 is movable in the X direction and the Y direction. The movable object 200 may be movable in the Z direction.

  The lock mechanism 100 fixes and releases the movable object 200 in the Y direction. The lock mechanism 100 may fix and unlock the movable object 200 also in the X direction or the Z direction.

  The control unit 310 controls the movement of the movable object 200 in the X direction and the Y direction. The controller 310 may also control the movement of the movable object 200 in the Z direction.

  Lock mechanism 100 includes a fixing portion 160, a lever 110, and a retainer 150.

  The fixed portion 160 locks the movement of the movable object 200 toward the Y-side at a predetermined fixed position. Here, the predetermined fixing position is the Y-side of the lever 110.

  The lever 110 can be locked to the movable object 200 from the Y + side. The lever 110 is urged from the Y + side.

  The retainer 150 can be locked to the lever 110 from the X-side at a predetermined position in the lever 110 in the Y direction (for example, a position of a locking portion 120 (described later)). The retainer 150 is biased from the X-side. Further, the retainer 150 can be released from the lock on the lever 110 by being moved to the X-side by the movable object 200.

  Details of an example of the configuration of the lock mechanism 100 shown in FIG. 2 will be described.

  The urging with respect to the retainer 150 is realized by the elastic force of an elastic body connected to the retainer 150, for example. The retainer 150 is, for example, a rectangular plate perpendicular to the Y direction.

  The lever 110 includes, for example, an urging portion 130 and a locking portion 120. The lever 110 is, for example, a long plate having the Y direction as the long side, the X direction as the short side, and perpendicular to the Z direction.

  The locking part 120 has a shape that can be locked and released from the retainer 150. When the locking part 120 is locked to the retainer 150, the movable object 200 has a shape that can be unlocked from the retainer 150 by pushing the retainer 150 to the X− side. The locking part 120 has a shape for locking the lever 110 about the Y-side when locked to the retainer 150. The locking part 120 has a shape that does not lock the lever 110 in the Y direction when not locked to the retainer 150. The locking portion 120 is, for example, a notch formed on the Y-side and the X-side of the long plate of the lever 110.

  The biasing portion 130 has a shape that can be locked and unlocked with respect to the movable object 200 from the Y + side. The urging portion 130 has a shape that can be locked to the movable object 200 when the locking portion 120 is released from the retainer 150. If the urging unit 130 is engaged with the movable object 200 and the engagement part 120 is not engaged with the retainer 150, the urging unit 130 urges the movable object 200 toward the Y-side. The urging of the urging unit 130 is realized by, for example, the elastic force of an elastic body connected to the urging unit 130. The urging unit 130 is, for example, a plate that stands upright from the long plate to the Z + side on the Y + side of the long plate of the lever 110.

  The operation in this embodiment will be described.

  An operation in which the movable object moving device 300 fixes the movable object 200 will be described.

  FIG. 3 is a plan view for explaining the operation of the movable object moving device according to the first embodiment of the present invention. Specifically, FIG. 3 is a snapshot at each stage of the operation of the movable object moving device 300. However, FIG. 3 shows an example in which the movable object 200 has a shape including the shaft portion 220 in addition to the main body portion 210.

  FIG. 4 is a flowchart showing an operation of fixing the movable object of the movable object moving device according to the first embodiment of the present invention. Note that the flowchart shown in FIG. 4 and the following description are merely examples, and the processing order and the like may be changed, the processing may be returned, or the processing may be repeated depending on the processing that is appropriately obtained.

  First, the lever 110 and the fixed portion 160 do not fix the movable object 200 (FIG. 3A, step S110 in FIG. 4). Here, for example, since the locking portion 120 is locked to the retainer 150, the lever 110 is prevented from moving to the Y-side.

  Next, the control unit 310 moves the movable object 200 to the first preparation position 410 (step S120 in FIG. 4). Here, the first preparation position 410 is a position in the X direction in which the movable object 200 can move to the second preparation position 420 without colliding with the lock mechanism 100. Further, the second preparation position 420 is a position in the Y direction where the retainer 150 can be released from the lever 110 when the movable object 200 moves in the X direction. In FIG. 3, the first preparation position 410 and the second preparation position 420 are illustrated with the X− side and Y + side ends of the movable object 200 as reference positions of the movable object 200.

  Subsequently, the control unit 310 moves the movable object 200 to the second preparation position 420 (step S130 in FIG. 4).

  Subsequently, the movable object 200 moves to the X-side and pushes out the retainer 150 (FIG. 3B, step S140 in FIG. 4).

  Subsequently, the locking portion 120 is released from the retainer 150 (FIG. 3C, step S150 in FIG. 4).

  Subsequently, the lever 110 is urged to the Y-side (step S160 in FIG. 4).

  Subsequently, the lever 110 and the fixing unit 160 fix the movable object 200 in the Y direction (FIG. 3D, step S170 in FIG. 4).

  An operation in which the movable object moving device 300 releases the fixation of the movable object 200 will be described.

  FIG. 5 is a flowchart showing an operation of releasing the fixation of the movable object of the movable object moving device according to the first embodiment of the present invention. Note that the flowchart shown in FIG. 5 and the following description are merely examples, and the processing order and the like may be changed, the processing may be returned, or the processing may be repeated depending on the processing that is appropriately obtained.

  First, the lever 110 and the fixed portion 160 fix the movable object 200 in the Y direction (FIG. 3D, step S210 in FIG. 5). Here, for example, since the locking portion 120 is not locked to the retainer 150, the lever 110 is urged to the Y-side.

  Next, the control unit 310 moves the movable object 200 to the third preparation position 430 (step S220 in FIG. 5). Here, the third preparation position 430 is a position in the Y direction where the retainer 150 can be locked to the lever 110 (for example, the locking portion 120) by the movable object 200 moving in the X direction. In FIG. 3, the third preparation position 430 is illustrated with the X− side and Y + side end of the movable object 200 as the reference position of the movable object 200.

  Subsequently, the control unit 310 moves the movable object 200 to a position in the X direction where the movable object 200 is unlocked from the lever 110 (step S230 in FIG. 5).

  Subsequently, the lever 110 moves to the Y-side (step S240 in FIG. 5).

  Subsequently, the lever 110 (for example, the locking portion 120) is locked to the retainer 150 (step S250 in FIG. 5).

  Subsequently, the lever 110 is not biased to the Y-side (step S260 in FIG. 5).

  Subsequently, the lever 110 and the fixing unit 160 release the fixation of the movable object 200 (FIG. 3A, step S270 in FIG. 5).

  As described above, the movable object moving device 300 in the present embodiment includes the lock mechanism 100. The lock mechanism 100 is engaged with the fixed portion 160 that locks the movement of the movable object 200 to the Y-side at a predetermined fixed position, the retainer 150 biased from the X-side, and the retainer 150. And a lever 110 biased from the Y + side that can be unlocked. When the movable object 200 is not fixed by the lock mechanism 100, the movable object moving device 300 can unlock the lever 110 from the retainer 150 by moving the movable object 200. Then, the movable object moving device 300 allows the movable object 200 from the Y + side by the lever 110 and locks the movement of the movable object 200 from the fixed portion 160 to the Y− side at a predetermined fixed position. The animal 200 is fixed in the Y direction. Further, when the movable object 200 is fixed by the lock mechanism 100, the movable object moving device 300 can lock the lever 110 to the retainer 150 by moving the movable object 200. Then, the lock mechanism 100 releases the fixation of the movable object 200 in the Y direction when the movable object 200 is not urged from the Y + side by the lever 110. Since the lock mechanism 100 includes parts having three simple shapes (fixing portion 160, retainer 150, and lever 110), it is easy to reduce the size. In addition, the lock mechanism 100 operates by locking and unlocking parts having three simple shapes when the movable object 200 is fixed or unlocked, and thus has high durability. Therefore, the movable object moving device 300 according to the present embodiment has an effect that it is possible to reduce the size and durability of the movable object lock mechanism.

  The movable object moving device 300 may include another movable object that is fixed and released when the movable object 200 is fixed and released.

The movable object moving device 300 may also fix the movable object 200 or another movable object in the X direction or the Z direction when the movable object 200 or another movable object is fixed in the Y direction.
(Second Embodiment)
Next, a second embodiment of the present invention based on the first embodiment of the present invention will be described. The movable object moving device in the present embodiment includes another movable object that is fixed and released in response to the fixation and release of the movable object. Moreover, the movable object moving apparatus in the embodiment fixes the movable object and another movable object also in the X direction or the Z direction.

  With reference to FIG. 1 again, the configuration of the present embodiment will be described.

  The movable object moving device 301 in the present embodiment includes a lock mechanism 101, a movable object 201, a movable object 251, and a control unit 311.

  FIG. 6 is a plan view illustrating the configuration and operation of the movable object moving device according to the second embodiment of the present invention. Specifically, FIG. 6 shows an example of the configuration of the movable object moving device 301 and a snapshot at each stage of operation.

  The lock mechanism 101 includes a fixing portion 161, a lever 111, and a retainer 150.

  The control unit 311 controls the movement of the movable object 201 and the movable object 251 in the X direction and the Y direction. The control unit 311 may also control the movement of the movable object 201 and the movable object 251 in the Z direction.

  The lever 111 locks the movable object 201 from the Y + side, and the fixing unit 161 locks the movable object 201 at a predetermined fixed position, so that the lock mechanism 101 fixes the movable object 201 in the Y direction.

  When the movable part 201 is locked on the Y-side, the fixed part 161 has a shape that locks the movable object 201 so as not to move in one or two directions orthogonal to the Y direction. Here, the one direction is an arbitrary direction in the XZ plane, and is the X direction in the example shown in FIG. The two directions are arbitrary two directions different from each other in the XZ plane, for example, the X direction and the Z direction.

  The movable object 201 has a locking end 231 on the Y-side, for example. And the fixing | fixed part 161 latches the latching end 231 in the Y- side. For example, the fixing portion 161 has a shape that can be fitted to the unevenness on the surface of the locking end 231 on the surface that is locked to the locking end 231. For example, when the locking end 231 has a convex shape composed of two side surfaces of a triangular prism, the fixing portion 161 has a concave surface that can be fitted to the convex surface on the surface that is locked to the locking end 231. Alternatively, for example, when the locking end 231 has a convex shape formed of a conical side surface, the fixing portion 161 has a concave surface that can be fitted to the convex surface on the surface locked to the locking end 231. Alternatively, for example, when the locking end 231 has a convex shape formed of each side surface of a pyramid, the fixing portion 161 has a concave surface that can be fitted to the convex surface on a surface locked to the locking end 231. The unevenness may be reversed.

  The lever 111 has a movement restraining mechanism 171. The movement inhibiting mechanism 171 inhibits the movement of the movable object 251 on the Y + side with respect to the lever 111 when the lock mechanism 101 fixes the movable object 201. The movement inhibiting mechanism 171 also inhibits the movement of the movable object 251 relative to the lever 111 in the X direction or the Z direction when the lock mechanism 101 fixes the movable object 201.

  The movable object 251 is locked to the Y-side at another predetermined fixed position. The movable object 251 is movable in the Y direction except that the movement toward the Y-side is locked at another predetermined fixed position. The movable object 251 can also move in the X direction or the Z direction. However, the movable object 251 is assumed to be movable to a position that can be locked to the movement restraining mechanism 171 before the lock mechanism 101 fixes the movable object 201 in the Y direction.

  For example, when the movable object 251 has a concave shape composed of two side surfaces of a triangular prism, the movement suppression mechanism 171 has a convex surface that can be fitted to the concave surface on the surface that is engaged with the movable object 251. Alternatively, for example, when the movable object 251 has a concave shape formed of a conical side surface, the movement suppression mechanism 171 has a convex surface that can be fitted to the concave surface on a surface that is engaged with the movable object 251. Alternatively, for example, when the movable object 251 has a concave shape formed of each side surface of a pyramid, the movement suppression mechanism 171 has a convex surface that can be fitted to the concave surface on a surface that is locked to the movable object 251. The unevenness may be reversed.

  Other configurations in the present embodiment are the same as those in the first embodiment of the present invention.

  As described above, in the movable object moving apparatus 301 according to the present embodiment, when the fixed unit 161 locks the movable object 201 from the Y-side, the movable object 201 cannot be moved in the X direction or the Z direction. Stop. That is, the movable object 201 is fixed in two directions (on one straight line) or in three directions (one point). Therefore, the movable object moving apparatus 301 in the present embodiment has an effect that the movable object 201 can be more stably fixed.

In the movable object moving device 301, when the lever 111 locks the movable object 251 from the Y + side, the movable object 251 is locked so as not to move in the X direction or the Z direction. That is, the movable object 251 is fixed in two directions (on one straight line) or in three directions (one point). Therefore, the movable object moving device 301 in the present embodiment has an effect that the movable object 251 can be fixed. Further, the movable object moving device 301 in the present embodiment has an effect that the movable object 251 can be stably fixed on one straight line or at one point.

  FIG. 19 is a flowchart showing a library unlocking operation according to the third embodiment of the present invention.

  Note that the flowcharts shown in FIGS. 18 and 19 and the following description are merely examples, and the processing order and the like may be changed, the processing may be returned, or the processing may be repeated depending on the processing that is appropriately obtained.

  When the soft power source (not shown) in the library 1 is cut off or when the library 1 is in the sleep mode, the picker base 7 moves to the Z-side hard stop position (step S310 in FIG. 18).

  FIG. 10 shows a state in which the accessor 6 that has received a movement instruction from the control unit (not shown) included in the library 1 to the position in the transportation lock state (transportation lock position) is moving to the transportation lock position. Here, the transport lock position of the accessor 6 is a position further moved to the X-side than the front side of the Y-side of the use area 22 at the time of cartridge delivery.

  FIG. 11 shows the following state (step S320 in FIG. 18). First, as a result of the accessor 6 being further moved to the X-side, the picker arm 13 is completely moved to the X-side position from the use area 22 at the time of cartridge delivery. After that, as a result of the picker 8 moving to a position that exceeds the transport lock position to the Y + side, the picker 8 moves to a position immediately before the X + side of the position where the transport lock mechanism 9 is operated.

FIG. 12 shows that as a result of the accessor 6 being further moved to the X-side, the picker arm 13 installed on the picker 8 pushes the shipping lock retainer 15 to the X-side, and the fixing of the shipping lock lever 14 by the shipping lock retainer 15 is released. This represents the state (step S330 in FIG. 18).
FIG. 13 shows a state in which the shipping lock lever 14 that biases the picker arm 13 to the Y-side as a result of the picker 8 moving to the Y-side has also moved to the Y-side (transportation locked state) (step of FIG. 18). S340).

  In FIG. 14, the accessor 6 is restricted from moving to the X + side by contact with the shipping lock lever 14 and the accessor movement restriction region 20, and is restricted from moving to the X− side by contact with the housing of the library 1. Represents the state. Further, FIG. 14 shows that the picker base 7 is restricted from moving to the Z + side by the contact between the shipping lock lever 14 and the picker movement restricting region 21 and moved to the Z− side by the contact with the housing of the accessor 6. Represents a restricted state (the first half of step S350 in FIG. 18).

  FIG. 15 shows a state in which the shipping lock lever 14 is restricted from moving to the Y− side by contact with the shipping lock retainer 15 and is restricted from moving to the Y + side by urging by the lock lever spring 17. As a result of the movement of the shipping lock lever 14 being restricted, the movement in the Y direction of the picker 8 engaged with the shipping lock lever 14 via the picker arm 13 is also restricted (the second half of step S350 in FIG. 18).

  FIG. 16 shows that when a power source (not shown) in the library 1 is turned on or when the library 1 is released from the hibernation mode, the picker 8 moves to the Y + side and moves the shipping lock lever 14 to the Y + side. Represents the state. As a result, the movement restriction of the accessor 6 and the picker base 7 by the shipping lock lever 14 is released (step S410 in FIG. 19).

  FIG. 17 shows that as a result of the movement of the accessor 6 to the X + side, the locking between the picker arm 13 and the shipping lock lever 14 is released, and at the same time, the shipping lock retainer 15 is pushed by the retainer spring 19 and moves to the X + side. In this state, the shipping lock lever 14 is fixed (steps S420 and S430 in FIG. 19).

  A control unit (not shown) included in the library 1 performs an initialization operation for searching for the origin in the movement of the picker 8 in the Y direction and the origin in the movement of the accessor 6 in the X direction (step S440 in FIG. 19).

  As described above, the library 1 in the present embodiment includes the transport lock mechanism 9. The transport lock mechanism 9 includes a biased shipping lock retainer 15 and a biased shipping lock lever 14 that can be engaged with and released from the shipping lock retainer 15. When the picker arm 13 is not fixed by the transport lock mechanism 9, the library 1 can unlock the shipping lock lever 14 from the shipping lock retainer 15 by moving the picker arm 13. The library 1 fixes the picker arm 13 by urging the picker arm 13 with the shipping lock lever 14. Further, when the picker arm 13 is fixed by the transport lock mechanism 9, the library 1 can engage the shipping lock lever 14 with the shipping lock retainer 15 by moving the picker arm 13. Then, the transport lock mechanism 9 releases the picker arm 13 from being fixed when the picker arm 13 is not biased by the shipping lock lever 14. As the picker arm 13 is fixed or released, the picker 8 and the accessor 6 connected to the picker arm 13 are fixed or released. Since the transport lock mechanism 9 is composed of two parts (shipping lock lever 14 and shipping lock retainer 15) having simple shapes, it is easy to reduce the size. Further, since the transport lock mechanism 9 operates by locking and unlocking parts having two simple shapes, the transport locking mechanism 9 has high durability. Therefore, the library 1 according to the present embodiment has an effect that the lock mechanism of the movable object can be downsized and the durability can be improved.

  In the library 1 according to the present embodiment, the picker 8 and the accessor 6 are fixed and released by the transport lock mechanism 9 so that the picker 8 and the accessor 6 can carry out the normal operation (or the natural operation). This is realized by extension. Therefore, the library 1 in the present embodiment has an effect that a dedicated mechanism for fixing and releasing by the transport lock mechanism 9 is unnecessary.

  In the library 1 according to this embodiment, the transport lock mechanism 9 is fixed to the housing of the library 1. The positions of the picker 8 and the accessor 6 that pass when the transport lock position and the transport lock are set and released are different from the positions that the picker 8 and the accessor 6 pass when the cartridge 5 is transported. Therefore, the library 1 according to the present embodiment has an effect that the number of operations of the transport lock mechanism 9 can be suppressed without increasing the accessor 6.
