Description

  The present invention relates to an accessor transfer device for transferring a hand accessor, and a library device using the accessor transfer device.

  Currently, library devices such as tape library devices are used to store large-capacity data with low access frequency. In such a library apparatus, electronic data is recorded on a magnetic tape or the like accommodated in a box-shaped medium.

  In such a library apparatus, a plurality of media are arranged and loaded in a rectangular parallelepiped magazine in the left-right direction. Further, in a deep type library apparatus, a plurality of media are arranged and loaded in a magazine in the front-rear direction.

  A general library apparatus is formed with a magazine storage section in which a magazine is inserted in the left-right direction and loaded. Furthermore, there are currently multi-layered library devices in which a plurality of media are arranged not only in the left-right direction but also in the up-down direction and loaded into a magazine, and a plurality of magazines are arranged in the up-down direction and loaded.

  In such a multi-layered library apparatus, a hand accessor transferred by an accessor transfer apparatus puts and removes a medium into and from a magazine in a plurality of magazine storage units arranged in the vertical direction.

  In such an accessor transfer device of the library apparatus, in order to move the hand accessor up and down, for example, a frame-like accessor moving mechanism for moving the hand accessor up and down is formed.

  Further, in order to move the accessor moving mechanism in the left-right direction, a rack and pinion is installed in the lower part of the accessor transfer device, and a guide rail is installed in the upper part. The accessor moving mechanism is moved in the left-right direction by the lower rack and pinion with the upper part supported by the guide rail.

  Since the hand accessor moves vertically in such an accessor moving mechanism, the hand accessor of the accessor transfer device can now access a plurality of magazine storage units arranged in the library device in the vertical direction. (For example, refer to Patent Document 1).

  As described above, in the deep type library apparatus, a plurality of media are loaded in the front-rear direction in a rectangular parallelepiped magazine. For this reason, when the magazine is stored in the magazine storage section of the library apparatus, the hand accessor can directly access the medium in front of the magazine, but cannot access the medium on the back side.

  In order to solve this, in the deep type magazine, when the medium on the front side is taken out, the medium on the back side is urged by the bullet mechanism so that it moves to the front. For this reason, a medium lock lever for holding the medium in front is mounted on the magazine so that a plurality of media loaded in the magazine do not jump out.

  The medium lock lever is elastically biased and is engaged with the medium in front, and is released when pressed by a hand accessor that moves to the left and right opposite to the elastic force. At this time, the medium engaging claw of the hand accessor engages with the medium held by the medium lock lever.

  For this reason, the hand accessor releases the medium lock lever and simultaneously engages the medium engaging claw with the medium, so that the medium in front can be pulled out. When the medium in front is pulled out to the hand accessor in this way, the medium on the back side is pressed by the bullet mechanism in the magazine and moves to the front.

JP 2011-204293 A

  As described above, in the deep type magazine, the medium lock lever that holds the plurality of media loaded in the magazine by being urged by the bullet mechanism is pressed and released by the hand accessor that moves to the left and right.

  However, the accessor moving mechanism for moving the hand accessor up and down as described above is moved in the left-right direction by the lower rack and pinion with the upper part supported by the guide rail. In other words, in the accessor transfer device as described above, the medium lock lever is released by the pressure of the rack and pinion.

  For this reason, in a state where the hand accessor is positioned below, the pressure of the rack and pinion is well transmitted from the accessor moving mechanism to the hand accessor, and the medium lock lever is reliably pressed and released.

  However, in a state where the hand accessor is positioned above, the accessor moving mechanism may be deformed or inclined, and the pressure of the rack and pinion may not be transmitted well to the hand accessor, and the medium lock lever may not be released. This problem becomes more serious as the number of stages of the multilayer structure of the magazine storage portion of the library apparatus is increased.

  In addition, when performing maintenance and inspection of the hand accessor, the accessor moving mechanism may be removed from the library apparatus. In this case, the work is performed in a state where the power of the library apparatus is turned off, and the operator pulls out the accessor moving mechanism by hand. At this time, if the accessor moving mechanism is deformed or inclined, it may be difficult to take out the accessor moving mechanism.

  The present invention has been made in view of the above-described problems, and provides an accessor transfer device that can suppress deformation and inclination of an accessor moving mechanism, and a library device using such an accessor transfer device. is there.

A driven gear G16 is fixed to the lower end portion of the drive shaft 1150, and an intermediate gear G13 constituting the lower gear train 1134 is engaged with the driven gear G16.

  In such a downward drive mechanism 1130, when the drive shaft 1136b is rotated by the drive source 1136, the pinion gear G15 of the lower pinion 1133 is moved via the drive gear G10 and the plurality of gears G12 to G14 constituting the lower gear train 1134. Driven by rotation. As a result, the pinion gear G15 moves while rotating along the rack 1132, and moves the lower lift plate 1122, that is, the lower part of the accessor lift 1120, in the left-right direction along the lower guide rail 1131.

  As shown in FIGS. 3, 11 to 13, and 17 to 19, the intermediate gear G <b> 21 that is the upper gear 1144 and the pinion gear G <b> 22 that is the upper pinion 1143 that constitute the upper drive mechanism 1140 are respectively connected to the rotation shafts 21 s. , 22s are supported by a lift upper plate 1121 (see FIG. 3) so as to be rotatable about an axis and mesh with each other.

  An upper end portion of the drive shaft 1150 is supported by a lift upper plate 1121 (see FIG. 3) so as to be rotatable around an axis. A drive gear G23 is provided at the upper end of the drive shaft 1150. When the drive gear G23 is engaged with the intermediate gear G21, the rotational force from the drive source 1136 is transmitted from the lower drive mechanism 1130 side to the upper drive mechanism 1140 via the drive shaft 1150, and the pinion gear G22 rotates via the gear G21. Driven. Thus, the pinion gear G22 moves while rotating along the upper rack 1142, and moves the lift upper plate 1121, that is, the upper part of the accessor lift 1120, in the left-right direction along the upper guide rail 1141.

By the way, as shown in FIGS. 18 and 19, the above-described drive gear G23 as an example of the disengagement mechanism and the gear has a first position P1 at which the pinion gear G22 can be driven by meshing with the intermediate gear G21, and the first position P1. The position P1 is offset along the axial direction of the drive shaft 1150 and is separated from the intermediate gear G21 so as to be movable between the second position P2 where the pinion gear G22 cannot be driven.
That is, as shown in FIGS. 17 to 20, a flat portion 1152 that is continuous along the axial direction of the drive shaft 1150 is formed in the upper portion of the drive shaft 1150. In the portion where the flat portion 1152 is formed, the drive shaft 1150 has a substantially D-shaped cross section orthogonal to the axial direction. On the other hand, a shaft support hole 1153 having a D-shaped cross section corresponding to the drive shaft 1150 having a D-shaped cross section is formed in the drive gear G23. The drive gear G23 is formed with a flat surface portion 1152 while the rotation of the drive shaft 1150 in the circumferential direction is restricted by inserting the upper end portion of the drive shaft 1150 into the shaft support hole 1153. Within the range, it can slide in the axial direction of the drive shaft 1150. Here, the plane portion 1152 is formed in a range in which the drive gear G23 can slide between the first position P1 and the second position P2.

An arm 1154 as an example of a lock member extending along the axial direction of the drive shaft 1150 is integrally formed on the drive gear G23 via a cylindrical sleeve 1158 as a lock member. The arm 1154 is a flat plate having a rectangular cross section, and a reinforcing rib 1155 is integrally formed at a connection portion with the drive shaft 1150 to increase the bending strength at the proximal end portion of the arm 1154 on the pinion gear G22 side.
Further, a C-shaped clamp claw member as an example of an engaging claw and a lock member formed at the lower end portion of the arm 1154 so as to be orthogonal to the extending direction of the arm 1154 and project toward the drive shaft 1150 side. 1156 is provided. The clamp claw member 1156 can be elastically deformed in a direction in which both end portions 1156a and 1156a approach and separate from each other.
A groove 1157 is continuously formed in the drive shaft 1150 in the circumferential direction. As shown in FIGS. 18A and 19A, the C-shaped clamp claw member 1156 is at the first position P1 where the pinion gear G22 can be driven by the engagement of the drive gear G23 with the intermediate gear G21. Sometimes, it can be fitted into the groove 1157. By inserting the C-shaped clamp claw member 1156 into the groove 1157, the drive gear G23 is restrained in the axial direction of the drive shaft 1150 at the first position P1.
Then, as shown in FIGS. 18B and 19B, when both end portions 1156a and 1156a of the C-shaped clamp claw member 1156 are pressed in a direction orthogonal to the axial direction of the drive shaft 1150, the C-shape When the claw-shaped clamping claw member 1156 interferes with the groove 1157 of the drive shaft 1150, both end portions 1156a and 1156a are opened in a direction away from each other. At the same time, the arm 1154 is bent around the upper end portion on the drive gear G23 side. As a result, the C-shaped clamp claw member 1156 is moved in a direction orthogonal to the axial direction of the drive shaft 1150 to be detached from the groove 1157, and the restraint in the axial direction of the drive shaft 1150 can be released. Then, the drive gear G23 can be slid along the axial direction of the drive shaft 1150, and can be retracted from the first position P1 to the second position P2.

  In the present embodiment, to simplify the drawing, the lower rack 1132 is illustrated as a part of the lower guide rail 1131 and the upper rack 1142 is illustrated as a part of the upper guide rail 1141.

  However, in practice, the lower rack 1132 is formed over the substantially entire length of the lower guide rail 1131, and the upper rack 1142 is formed over the substantially entire length of the upper guide rail 1141.

  In the configuration as described above, the library apparatus 1000 of the present embodiment is also a deep type multi-layered tape library apparatus, and a plurality of media 1310 containing magnetic tapes are arranged in a magazine 1320 in the front-rear and up-down directions. The plurality of magazines 1320 are loaded and individually accommodated in a plurality of magazine storage units 1210 arranged in the vertical direction.

  As described above, in the deep type magazine 1320, when one medium 1310 is removed, the medium 1310 is urged by the bullet mechanism so that the other medium 1310 moves to the front.

  For this reason, as shown in FIG. 14, a medium lock lever for holding the medium 1310 on the front side of the front side of the magazine 1320 so that the plurality of mediums 1310 loaded in the magazine 1320 do not jump forward. 1321 is mounted.

  Since the medium lock lever 1321 is urged to the right, when the hand accessor 1110 accesses the medium 1310 on the front side locked by this, the hand accessor 1110 is moved to the rear as shown in FIG. 15 and FIG. The medium lock lever 1321 is pushed leftward by the stopper engaging portion 1112 on the left end, and is displaced.

  At this time, the medium engagement claw 1111 on the right side of the rear end of the hand accessor 1110 engages with the engagement recess of the medium 1310 on the front side, so that the medium 1310 is held by the hand accessor 1110 without protruding forward due to the elastic force. Is done.

  Since the library apparatus 1000 of this embodiment is a deep type and has a multilayer structure as described above, a plurality of media 1310 are also arranged in the vertical direction and are detachably loaded as shown in FIG.

  The accessor lift 1120 that supports the hand accessor 1110 up and down is formed into a rectangular frame shape by a lift upper plate 1121, a lift lower plate 1122, a lift left portion 1123, and a lift right portion 1124. ing. For this reason, there is a concern that the accessor lift 1120 may be deformed or inclined when stress is applied to the upper side and the lower side in the left-right direction on the opposite side.

  However, in the accessor transfer device 1100 of the library apparatus 1000 according to the present embodiment, the stress of the hand accessor 1110 that presses the medium lock lever 1321 as described above causes the lower and upper portions of the accessor lift 1120 supporting the hand accessor 1110 to The lower drive mechanism 1130 and the upper drive mechanism 1140 act in common.

  Therefore, even when the hand accessor 1110 is positioned above the accessor lift 1120, the accessor lift 1120 is deformed by the power of the lower drive mechanism 1130 and the upper drive mechanism 1140 and the reaction force of the medium lock lever 1321, and the hand accessor 1110. However, it is possible to prevent the medium lock lever 1321 from being unlocked.

  That is, even if the accessor transfer device 1100 of the library apparatus 1000 of the present embodiment is a deep type and has a multilayer structure, the hand accessor 1110 can reliably insert and remove an arbitrary medium 1310.

  Therefore, it is not necessary to reinforce the accessor lift 1120 formed in the rectangular frame shape by the lift upper plate 1121, the lift lower plate 1122, the lift left portion 1123, and the lift right portion 1124 so as not to be deformed or inclined. The existing accessor lift 1120 can be used.

  Moreover, in the accessor transfer device 1100 of this embodiment, the lower drive mechanism 1130 includes the drive source 1136, and the drive of the lower drive mechanism 1130 and the upper drive mechanism 1140 is mechanically interlocked by the drive shaft 1150.

  Therefore, it is not necessary to mount the drive source 1136 on both the lower drive mechanism 1130 and the upper drive mechanism 1140, and the upper drive mechanism 1140 can be downsized. In particular, the current library apparatus is equipped with a lower drive mechanism 1130 having a drive source 1136.

  For this reason, if the upper drive mechanism 1140 and the drive shaft 1150 are added to the accessor transfer device of the existing library apparatus, the library apparatus 1000 of this embodiment can be easily realized.

  Further, in the existing library apparatus, it is difficult to mount the drive source 1136 on the upper part due to a structural problem, but the upper drive mechanism 1140 including the upper gear 1144, the upper pinion 1143, and the like can be mounted without any problem. . In particular, since the drive shaft 1150 has a simple structure and a planar area occupied to a minimum, it can be easily added to an accessor transfer device of an existing library device.

  Further, in the accessor transfer device 1100 of the library apparatus 1000 of the present embodiment, the lower drive mechanism 1130 and the upper drive mechanism 1140 have a rack and pinion, and the lower rack 1132 is integrally formed in parallel with the lower guide rail 1131. The upper rack 1142 is integrally formed in parallel with the upper guide rail 1141.

  Therefore, it is possible to form the lower rack 1132 and the upper rack 1142 simply by modifying the existing lower guide rail and upper guide rail, and it is necessary to add the lower rack 1132 and the upper rack 1142 as new parts. Absent.

  Since the lower drive mechanism 1130 and the upper drive mechanism 1140 made of rack and pinion are mechanically interlocked by simply connecting them with the drive shaft 1150 as described above, the upper drive mechanism corresponds to the drive of the lower drive mechanism 1130. There is no need to control the driving of 1140.

  Further, since the drive shaft 1150 is connected to the lower gear train 1134 of the lower drive mechanism 1130 and the upper gear 1144 of the upper drive mechanism 1140, as shown in the drawing, the lower pinion 1133 and the upper pinion 1143 having different numbers of teeth Can be driven appropriately.

Incidentally, the hand accessor 1110 may be taken out from the library apparatus 1000 when performing work such as maintenance and inspection of the hand accessor 1110. In this case, the work is performed with the power supply of the library apparatus 1000 turned off, and the operator pulls out the accessor lift 1120 supporting the hand accessor 1110 up and down by hand. At this time, the accessor lift 1120 moves along the lower rack 1132 and the upper rack 1142 in a no-load state (a state where the power is turned off and the driving force from the driving source 1136 is not acting). At this time, in the upper drive mechanism 1140 and the lower drive mechanism 1130, as the accessor lift 1120 moves along the lower rack 1132 and the upper rack 1142, the lower pinion 1133 and the lower gear engaged with the lower rack 1132 and the upper rack 1142, respectively. Row 1134, drive shaft 1150, upper pinion 1143, and upper gear 1144 rotate.
When the height dimension of the accessor lift 1120 is large, an inclination may occur when the accessor lift 1120 is pulled out. Then, the difference in rotational resistance increases between the lower drive mechanism 1130 and the upper drive mechanism 1140, and the deformation and inclination of the accessor lift 1120 may be further deteriorated. Then, it becomes difficult to pull out the accessor lift 1120.

Therefore, as shown in FIGS. 18B and 19B, when performing work such as maintenance and inspection of the hand accessor 1110, the C-shaped clamp claw member 1156 is previously placed in the axial direction of the drive shaft 1150. Is moved away from the groove 1157 to release the restraint of the drive gear G23 in the axial direction of the drive shaft 1150, and then the arm 1154 is pulled downward. Then, the drive gear G23 is retracted from the first position P1 to the second position P2. In this state, the lower drive mechanism 1130 and the upper drive mechanism 1140 are disconnected from each other via the drive shaft 1150, and the lower drive mechanism 1130 and the upper drive mechanism 1140 can be independently rotated.
When the operator performs the above operation, the accessor lift 1120 is hardly deformed or inclined when the accessor lift 1120 is pulled out. Further, even if the accessor lift 1120 is inclined, the lower drive mechanism 1130 and the upper drive mechanism 1140 operate independently and smoothly. Therefore, the hand accessor 1110 can be easily pulled out and workability is improved.

  Further, in order to constrain the drive gear G23 in the axial direction of the drive shaft 1150 at the first position P1, an elastically deformable arm 1154 and a groove formed on the tip of the arm 1154 and formed in the drive shaft 1150 And a clamp claw member 1156 that can be engaged with 1157. Such a configuration is very simple and can be easily operated by an operator.

  In addition, this invention is not limited to said each embodiment, A various deformation | transformation is accept | permitted in the range which does not deviate from the summary. For example, in the above embodiment, the lower drive mechanism 1130 and the upper drive mechanism 1140 are mechanically interlocked with each other by the drive shaft 1150 that is a drive interlock mechanism.

  However, a gear train, a gear chain mechanism, a cocked belt mechanism, or the like can be used as a drive interlocking mechanism that mechanically interlocks the lower drive mechanism 1130 and the upper drive mechanism 1140 (not shown). .

  Further, in the above embodiment, the drive source 1136 is mounted on the lower drive mechanism 1130 and the drive source is not mounted on the upper drive mechanism 1140. However, the lower drive mechanism on which the drive source 1136 is not mounted and the upper drive mechanism on which the drive source is mounted may be coupled by a drive interlock mechanism such as the drive shaft 1150 (not shown). A drive source may be mounted on each of the lower drive mechanism and the upper drive mechanism that are not connected to each other (not shown).

  A worm mechanism, a gear chain mechanism, a cocked belt mechanism, a linear motor, a linear actuator, or the like can be used as the lower drive mechanism and the upper drive mechanism that are not mechanically connected by the drive interlocking mechanism in this way ( Not shown).

  Further, when individually driving the lower drive mechanism and the upper drive mechanism that are not mechanically connected by the drive interlocking mechanism in this way, for example, when the hand accessor 1110 is positioned below, The driving torque and moving position may be expanded from the upper driving mechanism, or when the hand accessor 1110 is positioned above, the driving torque and moving position of the upper driving mechanism may be expanded from the lower driving mechanism.

  Further, in the above embodiment, only the medium lock lever 1321 of the magazine 1320 is moved left and right with the hand accessor 1110 that moves left and right, but the present invention is not limited to this. For example, on a general medium 1310, a protect notch for setting recording permission and recording prohibition is mounted so as to be displaceable in the left-right direction (not shown).

  The protect notch is moved to the left and right by manual operation and is arranged at one of the data recording permission position and the prohibition position. When such a medium 1310 is loaded into the library apparatus 1000, the drive unit detects whether the protect notch is in the permitted position or the prohibited position (not shown), and the drive unit is only in the permitted position when the medium is in the permitted position. Data recording is executed at 1310.

  Therefore, when changing the setting of recording permission and recording prohibition of the medium 1310 accommodated in the library apparatus 1000, conventionally, the magazine 1320 is manually extracted from the library apparatus body, and the medium 1310 is manually operated from the magazine 1320. And the protect notch of the medium 1310 is displaced manually.

  Further, the medium 1310 in which the protect notch is displaced by manual operation in this way is reloaded in the magazine 1320 by manual operation, and the magazine 1320 is reloaded by manually operating the library apparatus main body.

  For this reason, it is complicated to change the medium 1310 loaded in the library apparatus 1000 to permit or prohibit recording as described above. Further, since it is necessary to execute all the operations manually as described above, the wrong medium 1310 may be changed in setting, or the changed medium 1310 may be loaded in the wrong position of the magazine 1320. It was.

  Moreover, as described above, the library apparatus 1000 loaded with the medium 1310 in the magazine 1320 executes the inventory process. For example, in the case of a deep type and a multi-layer structure, this inventory process requires several tens of minutes. For this reason, a great deal of time is required in total with the above-described manual operation.

  Therefore, the library apparatus 1000 as described above may include a notch engaging portion, a medium specifying unit, and an accessor control unit (not shown). The notch engaging portion is formed as a convex portion or the like on the rear surface of the hand accessor 1110, and engages and disengages with the protect notch.

  The medium specifying unit includes a keyboard and receives an input operation for specifying at least one for changing the setting of recording permission and recording prohibition from the medium 1310 loaded in the library apparatus 1000.

  The accessor control means includes a logic circuit that generates output data corresponding to input data, a microcomputer on which an appropriate computer program is mounted, and the like, and a hand that moves the protect notch of the medium 1310 to the left and right in response to an input operation. The notch engaging portion of the accessor 1110 is displaced in the left-right direction.

  In such a library apparatus 1000, it is possible to change the setting of recording permission and recording prohibition while the medium 1310 is loaded. Therefore, as described above, in order to change the setting of recording permission and recording prohibition of the medium 1310 loaded in the library apparatus 1000, the magazine 1320 is manually removed from the library apparatus body, and the medium 1310 is removed from the magazine 1320. The medium 1310 is removed by manual operation, the protect notch of the medium 1310 is manually displaced, the medium 1310 having the protect notch displaced by this manual operation is manually loaded into the magazine 1320, and the magazine 1320 is loaded into the library apparatus main body. There is no need to reload it manually.

  For this reason, the complicated work as described above is not necessary, and it is possible to prevent the wrong medium 1310 from being changed in setting or the medium 1310 whose setting has been changed from being loaded in the wrong position of the magazine 1320.

  In addition, since the inventory process executed when the medium 1310 is loaded in the library apparatus 1000 by the magazine 1320 as described above does not occur, the recording permission and the recording prohibition and setting of the medium 1310 accommodated in the library apparatus 1000 are performed. It can be changed very quickly.

In the above embodiment, the flat portion 1152 is formed on the upper portion of the drive shaft 1150, the upper portion of the drive shaft 1150 is substantially D-shaped in cross section, and the shaft support hole 1153 having a D-shaped cross section is formed in the drive gear G23. Has been. However, as long as the drive gear G23 can be slidably moved in the axial direction while being restricted in the rotational direction with respect to the drive shaft 1150, other configurations can be appropriately employed. For example, the drive shaft 1150 and the drive gear G23 may be connected by a spline, and the spline on the drive shaft 1150 side may be formed with a length corresponding to the sliding amount of the drive gear G23. In addition to this, the upper portion of the drive shaft 1150 and the shaft support hole 1153 of the drive gear G23 are formed in a polygonal shape such as a square shape, or a key groove continuous in the axial direction is provided on the upper portion of the drive shaft 1150, while the drive gear G23 is provided. A key that fits into the key groove may be provided in the shaft support hole 1153.
In addition to this, as long as it does not depart from the gist of the present invention, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
