Description

  The present invention relates to a rail member mounting jig.

  Conventionally, when an information processing apparatus is mounted on a rack, first, a pair of left and right rail members are attached to the rack, and the information processing apparatus is supported by the rail members attached to the rack. Here, the current situation is that the mounting operation of the rail member is performed depending on the visual observation of the operator. In other words, the mounting operation is performed by using marks such as marking lines provided on the rack so that the rail member does not tilt in the front-rear direction of the rack. However, the long rail member is inclined forward and backward, and can be screwed to the wrong mounting position. Such a situation can also occur when a skilled worker works. Moreover, although a rail member is normally made into a pair on the left and right, it may happen that the rail member is attached to different heights on the right and left sides of the rack.

  For these situations, it is conceivable to use a level, for example. For example, Patent Document 1 discloses a laser level. It is considered that the rail member can be accurately attached to the rack by using the laser level.

JP 2011-191320 A

  However, even if the laser level disclosed in Patent Document 1 is used, it is difficult to find out the exact mounting position of the rail member when it is unfamiliar with its handling. For this reason, even if a laser level or the like is used, the possibility that the rail member is still attached to the wrong position cannot be solved.

  In one aspect, the present invention is directed to facilitating accurate rail member attachment to a rack.

  The rail member mounting jig disclosed in the present specification includes a first rail mounting portion, a second rail mounting portion adjacent to the first rail mounting portion and the first direction side, the first rail mounting portion, and the A rail member attached to a rack, comprising: a third rail attachment portion adjacent to a second direction side different from the first direction; and a fourth rail attachment portion located diagonally to the first rail attachment portion. A mounting jig that is detachable from the first rail mounting portion, and that is directed toward the third rail mounting portion and a first launching portion that launches a detection medium toward the second rail mounting portion. A first unit that includes a second launching unit that launches a detection medium, and a first detection that is detachable with respect to the second rail attachment unit and detects arrival of the detection medium launched from the first launching unit. And the first detector detects the detection medium. A second unit comprising: a first attachment permission portion that permits attachment of a rail member to the second rail attachment portion; and a third launching portion that fires a detection medium directed toward the fourth rail attachment portion. A second detection unit that is detachable from the third rail attachment unit and detects the arrival of the detection medium emitted from the second emission unit; and when the second detection unit detects the detection medium A third unit including a second attachment permission portion that permits attachment of a rail member to the third rail attachment portion, and is detachable from the fourth rail attachment portion, and is emitted from the third launching portion. A third detection unit that detects arrival of the detected detection medium, and a third attachment permission unit that permits attachment of the rail member to the fourth rail attachment unit when the third detection unit detects the detection medium. That comprises a fourth unit.

  The first attachment permission portion permits attachment of the rail member when the heights of the first unit and the second unit match. The second attachment permission portion permits attachment of the rail member when the heights of the first unit and the third unit match. The third attachment permission portion permits attachment of the rail member when the heights of the second unit and the fourth unit match. As described above, the rail member mounting jig disclosed in this specification is permitted to be mounted when the mounting heights of the units coincide. In other words, when the mounting height does not match between the units, the operator cannot mount the rail member. For this reason, the situation where a rail member is attached diagonally in front and back, or it is attached in a step difference in right and left is avoided, and the attachment of a precise rail member to a rack becomes easy.

  According to one embodiment, accurate mounting of the rail member to the rack is facilitated.

≪Overall structure≫
First, the rack 100 to which the rail member 5 is mounted using the mounting jig 10 of the first embodiment will be described. In the following description, for the sake of convenience, the front-rear direction and the width (left-right) direction of the rack 100 are defined as shown in FIGS. The rack 100 includes a first support column 1 serving as a first rail mounting portion on the right front side. In the first embodiment, the first support column 1 is used as a reference. The rack 100 includes a first column 1 and a second column 2 adjacent to the left and right direction side. The 2nd support | pillar 2 is corresponded to a 2nd rail attaching part. The rack 100 includes a third column 3 adjacent to the first column in the front-rear direction. The 3rd support | pillar 3 is corresponded to a 3rd rail attachment part. The rack 100 includes a fourth column 4 positioned diagonally with the first column 1. The fourth support column 4 corresponds to a fourth rail mounting portion. As described above, the rack 100 includes rail mounting portions at the four corners. In the first embodiment, the first direction is the left-right direction and the second direction is the front-rear direction. However, the first direction can be the front-rear direction and the second direction can be the left-right direction.

  A pair of rail members 5 are attached to such a rack 100. One rail member 5 is attached to the first support column 1 and the third support column 3. The other rail member 5 is attached between the second support column 2 and the fourth support column 4.

  FIG. 3A to FIG. 3C show an example of variations of the rail member 5. 3 (A) to 3 (C) are marked with R indicating that they are attached to the right side of the rack 100. Each of the rail members 5 is attached to the rack 100 by being screwed at two places on the front side and two places on the rear side. The rail member 5a shown in FIG. 3 (A) has the same screwing position at the front and rear. In the rail member 5b shown in FIG. 3B, the interval between the screwing positions is different between the front and rear. In the rail member 5c shown in FIG. 3C, the interval between the screwing positions is different between the front and rear, and one screwing position is arranged close to the lower side. Thus, the shape of the rail member 5 is various. Since the rail member 5 is long, it is difficult to attach the rail member 5 to the correct position of the rack 100. Such a difference in shape also contributes to making it difficult to attach the rail member 5 correctly. ing. For this reason, when it is going to perform attachment work without using the attachment jig 1 of Example 1, there exists a possibility that the rail member 5 may become diagonal in front and back, or may be in the state where the height differs in right and left. is there.

  The mounting jig 10 includes a first unit 20 that is detachable with respect to the first support column 1, a second unit 40 that is removable with respect to the second support column 2, a third unit 60 that is removable with respect to the third support column 3, and a fourth unit. A fourth unit 80 detachably attached to the column 4 is included.

The first unit 20 includes a first light emitting unit 25, a second light emitting unit 26, a power source 27, and a display unit 28 in the housing 21. Here, the first light emitting unit 25 corresponds to a first emitting unit, and the second light emitting unit 26 corresponds to a second emitting unit. That is, in Example 1, a laser beam is used as the detection medium. Any detection medium may be employed as long as it proceeds toward the opposing detection units and can be confirmed by the detection unit to match the height position. For example, light having high straightness like the laser beam used in Example 1 is suitable as a detection medium.

  The 1st light emission part 25 emits the laser beam which goes to the 2nd support | pillar 2 side. The second light emitting unit 26 emits a laser beam toward the third support column 3 side. The changeover switch 22, the light emission switch 23, the first light emission unit 25, the second light emission unit 26, the power source 27, and the display unit 28 are all electrically connected to the control circuit 24. The change-over switch 22 switches which light is emitted between the first light emitting unit 25 and the second light emitting unit 26. The changeover switch 22 also serves as a power switch for the first unit 20. The light emitting switch 23 causes the selected side of the first light emitting unit 25 and the second light emitting unit 26 to emit light when pressed by the operator. The display unit 28 is an LED lamp, and indicates whether the first unit 20 is turned on or off, and indicates which of the first light emitting unit 25 and the second light emitting unit 26 is selected. The control circuit 24 controls the state of each unit in accordance with the operator's operation. Note that the power source 27 is built in the housing 21, but may be a type that is pulled in from the outside. Referring to FIG. A pin hole 21 a is provided on the bottom surface of the housing 21.

Here, the first light receiving unit 48 corresponds to a first detection unit, and the third light emitting unit 49 corresponds to a third emitting unit. The third light emitting unit 49 uses a laser beam as a detection medium in the same manner as the first light emitting unit 25 and the second light emitting unit 26.

  The first light receiving unit 48 detects the arrival of the laser beam emitted from the first light emitting unit 25 included in the first unit 20. The size of the first light receiving portion 48 is set to a size that cannot receive the laser beam even if the mounting of the rail member 5 is shifted by one mounting hole. The third light emitting unit 49 emits a laser beam toward the fourth support column 4 side. The first shielding plate 43 corresponds to a first attachment permission portion. The power switch 42, the motor 45, the light emitting switch 46, the first light receiving unit 48, the third light emitting unit 49, the power source 50, and the display unit 51 are all electrically connected to the control circuit 47. The power switch 42 turns the power of the second unit 40 on and off. The light emission switch 46 causes the third light emitting unit 49 to emit light when pressed by the operator. The display unit 51 is an LED lamp, and indicates whether the power of the second unit 40 is turned on or off, and also indicates the light emitting state of the third light emitting unit 49 and the light receiving state of the first light receiving unit 48. The 1st shielding board 43 interlocked with the motor 45 closes the object attachment hole provided in the 2nd support | pillar 2 when the 1st light-receiving part 48 has not detected the laser beam. Further, the first shielding plate 43 opens the target mounting hole by the rotation of the motor 45 when the first light receiving unit 48 detects the laser beam. Thereby, the operator can confirm the coincidence of the height positions, and can perform the attaching operation of the rail member 5. The control circuit 47 controls the state of each unit in accordance with the operator's operation. Although the power supply 50 is built in the housing 41, it may be of a type that is drawn from the outside. Referring to FIG. A pin hole 41 a is provided on the bottom surface of the housing 41.

≪Third unit≫
Next, the third unit 60 will be described with reference to FIGS. 2, 8 </ b> A, 8 </ b> B, and 9. FIG. 8A is a perspective view of the third unit 60 as viewed from above, and FIG. 8B is a perspective view of the third unit 60 as viewed from below. FIG. 9 is an exploded view of the third unit 60.

  The third unit 60 can be attached to and detached from the third support column 3 by using a table member 90 described in detail later. The third unit 60 includes a reversing switch 62, a motor 65, and a control circuit 66 in a housing 61. The third unit 60 includes a second light receiving unit 67, a power source 68, and a display unit 69 in the housing 61. A second shielding plate 63 is attached to the tip of a rotating shaft member 64 that is connected to the motor 65 and extends to the outside of the housing 61. Here, the second light receiving unit 67 corresponds to a second detection unit.

  The second light receiving unit 67 detects the arrival of the laser beam emitted from the second light emitting unit 26 included in the first unit 20. The size of the second light receiving portion 67 is set to such a size that the laser beam cannot be received even if the mounting of the rail member 5 is shifted by one mounting hole. The second shielding plate 63 corresponds to a second attachment permission portion. The reversing switch 62, the motor 65, the second light receiving unit 67, the power source 68, and the display unit 69 are all electrically connected to the control circuit 66. The reversing switch 62 switches the rotation direction of the motor 65. The reversing switch 62 also serves as a power switch for the third unit 60. The display unit 69 is an LED lamp, and indicates whether the third unit 60 is turned on or off, and also indicates the light receiving state of the second light receiving unit 67. The second shielding plate 63 interlocked with the motor 65 closes the target mounting hole provided in the third support column 3 when the second light receiving unit 67 does not detect the laser beam. Further, the second shielding plate 63 opens the target mounting hole by the rotation of the motor 65 when the second light receiving unit 67 detects the laser beam. Thereby, the operator can confirm the coincidence of the height positions, and can perform the attaching operation of the rail member 5. The second shielding plate 63 can be attached to the rotating shaft member 64 with the front and back reversed. The control circuit 66 controls the state of each part according to the operator's operation. Although the power source 68 is built in the housing 61, it may be of a type that is pulled in from the outside. Referring to FIG. A pin hole 61 a is provided on the bottom surface of the housing 61.

≪4th unit≫
Next, the fourth unit 80 will be described with reference to FIGS. 2 and 10. FIG. 10 is a perspective view showing a state in which the second shielding plate 63 included in the third unit is reversed to form the fourth unit 80. That is, the third unit 60 reverses the second shielding plate 63 upside down to form the third shielding plate 83 and attaches it to the rotating shaft member 64 (84), and reverses the rotation direction of the rotating shaft member 64 (84). There can be four units 8.

  The fourth unit 80 can be attached to and detached from the fourth support column 4 by using a table member 90 described in detail later. The fourth unit 80 includes an electric reversing switch 82, a motor 85, and a control circuit 86 in a housing 81. The fourth unit 80 includes a third light receiving unit 87, a power supply 88, and a display unit 89 in the housing 81. A third shielding plate 83 is attached to the tip of the rotating shaft member 84 that is connected to the motor 85 and extends to the outside of the housing 81. Here, the third light receiving unit 87 corresponds to a third detection unit.

  The third light receiving unit 87 detects the arrival of the laser beam emitted from the third light emitting unit 49 included in the second unit 40. The size of the third light receiving portion 87 is set to such a size that the laser beam cannot be received even if the rail member 5 is attached by one mounting hole. The third shielding plate 83 corresponds to a third attachment permission portion. The reversing switch 82, the motor 85, the third light receiving unit 87, the power supply 88, and the display unit 89 are all electrically connected to the control circuit 86. The reversing switch 82 switches the rotation direction of the motor 85. The reversing switch 82 also serves as a power switch for the fourth unit 80. The display unit 89 is an LED lamp and indicates whether the fourth unit 80 is turned on or off, and also indicates the light receiving state of the third light receiving unit 87. The 3rd shielding board 83 interlocked with the motor 85 closes the object attachment hole provided in the 4th support | pillar 4 when the 3rd light-receiving part 87 has not detected the laser beam. In addition, the third shielding plate 83 opens the target mounting hole when the motor 85 rotates when the third light receiving unit 87 detects a laser beam. Thereby, the operator can confirm the coincidence of the height positions, and can perform the attaching operation of the rail member 5. The control circuit 86 controls the state of each part in accordance with the operator's operation. Although the power supply 88 is built in the housing 81, it may be of a type that is pulled in from the outside.

  As described above, the fourth unit 80 is prepared by reversing the second shielding plate 63 of the third unit 60 so that the second shielding plate 63 is reversed and mounted on the rotating shaft member 64, and reversing the rotating direction of the rotating shaft member 64. be able to. For this reason, it is not always necessary to prepare the fourth unit 80 separately from the third unit 60. The worker may use the third unit 60 as the fourth unit 80 during the work.

≪Table material≫
Next, the table member 90 will be described with reference to FIGS. 11 (A) and 11 (B). FIG. 11A is a perspective view of the table member 90 as viewed from above, and FIG. 11B is a perspective view of the table member 90 as viewed from below. The table member 90 is used when attaching the first unit 20 to the fourth unit 80 to the first support column 1 to the fourth support column 4 included in the rack 100.

  The table member 90 includes an installation table 91 and a vertical plate 92 orthogonal to the installation table 91 and extending downward. The vertical plate 92 is provided with a protrusion 93 that is inserted into the mounting hole provided in each of the first support column 1 to the fourth support column 4. The protrusions 93 are provided on the left and right sides of the vertical plate 92. Thereby, it can attach to any support | pillar on either side. The table member 90 includes a mounting pin 94 on the installation table 91. The mounting pin 94 corresponds to a fixing portion that fixes any one of the first unit 20 to the fourth unit 80 to the table member 90. The mounting pin 94 is inserted into the pin holes 21 a, 41 a, 61 a, 81 a, and any one of the first unit 20 to the fourth unit 80 can be fixed on the installation base 91. The table member 90 can adjust the mounting height of the first unit 20 to the fourth unit 80 by selecting the mounting holes provided in the first column 1 to the fourth column 4 respectively.

≪How to use≫
Next, a usage example of the mounting jig 1 as described above will be described with reference to FIGS. FIG. 12 is an explanatory view showing a state in which the positions of the mounting holes are shifted before and after the rail member 5. FIG. 13 is an explanatory view showing a state where the mounting hole is shielded by the second shielding plate. FIG. 14A shows a state in which the positions of the mounting holes coincide before and after the rail member 5, and FIG. 14B is an explanatory view showing a state in which the shielding by the second shielding plate is released. FIG. 15 is an explanatory view showing a state in which the left and right rail members 5 are in a different state. FIG. 16 is an explanatory view showing a state where the mounting hole is shielded by the first shielding plate. FIG. 17A shows a state in which the left and right rail members have the same height, and FIG. 17B is an explanatory view showing a state in which the shielding by the first shielding plate is released.

  First, the operator attaches the table member 90 for the first unit 20 to the first support column 1 using a marking line or the like as a guide. The installation position of the table 90 is a reference for subsequent work. Next, the worker temporarily fixes the right rail member 5 to the first support column 1 using the attached table member 90 as a guide. Next, the worker moves to the rear side of the rack 100 and installs the table member 90 for the third unit 60 under the rail member 5 temporarily fixed to the first support column 1. After the mounting of the table member 90 is completed, the first unit 20 is installed on the table member 90 mounted on the first support column 1. The 1st unit 20 is located inside the 1st support | pillar 1, ie, the 2nd support | pillar 2 side. The operator installs the third unit 60 on the table member 90 installed on the third column 3. The third unit 60 is located on the inner side of the third column 3, that is, on the fourth column 4 side. At this time, the motor 65 included in the third unit 60 is set by the reversing switch 62 so as to rotate clockwise. Moreover, the 2nd shielding board 63 is the state which closed the object attachment hole.

  Next, the worker presses the light emission switch 23 provided in the first unit 20 and emits a laser beam from the second light emitting unit 26. If the positions of the first unit 20 and the third unit 60 are shifted as shown in FIG. 12, the laser beam is not irradiated to the second light receiving unit 67 as shown in an enlarged view in FIG. In such a state, the control unit 66 does not rotate the motor 65. That is, the target mounting hole is closed without rotating the second shielding plate 63. As a result, the operator cannot recognize the mounting position of the table member 90 because the mounting operation of the rail member cannot be performed. Then, the operator adjusts the position where the third unit 60 is attached to the third column 3. Then, when the laser beam is adjusted to the position where the second light receiving unit 67 receives light as shown in FIG. 14A, the control unit 66 issues a command to the motor 65, as shown in FIG. 14B. The second shielding plate 63 is rotated to open the target mounting hole. Thereby, the operator can attach the rail member 5 to the correct position. That is, the right rail member 5 can be attached to the rack 100 without being inclined in the front-rear direction.

  Next, the worker moves to mounting the left rail member 5. The table member 90 for the second unit 40 is mounted on the second support column 2 using a marking line or the like as a guide. Next, the operator temporarily fixes the left rail member 5 to the second support column 2 using the attached table member 90 as a guide. Next, the worker moves to the rear side of the rack 100 and installs the table member 90 for the fourth unit 80 under the rail member 5 temporarily fixed to the second support column 2. After the mounting of the table member 90 is completed, the second unit 40 is installed on the table member 90 mounted on the second support column 2. The 2nd unit 40 is located inside the 2nd support | pillar 2, ie, the 1st support | pillar 1 side. The operator installs the fourth unit 80 on the table member 90 installed on the fourth support column 4. The fourth unit 80 is located inside the fourth support column 4, that is, on the third support column 3 side. The fourth unit 80 is prepared by removing the third unit 60 and attaching the second shielding plate 63 with the front and back reversed. The motor 85 is set so as to be counterclockwise by the reversing switch 62 (84). The 3rd shielding board 83 is the state which closed the object attachment hole.

  Next, the operator sets the state in which the first light emitting unit 25 can emit light by the changeover switch 22 of the first unit 20, presses the light emitting switch 23, and emits a laser beam. If the positions of the first unit 20 and the second unit 40 are shifted as shown in FIG. 15, the laser beam is not applied to the first light receiving unit 48 as shown in an enlarged view in FIG. In such a state, the control unit 47 does not rotate the motor 45. That is, the target mounting hole is closed without rotating the first shielding plate 43. As a result, the operator cannot recognize the mounting position of the table member 90 because the mounting operation of the rail member cannot be performed. And an operator adjusts the attachment position to the 2nd support | pillar 2 of the 2nd unit 20. FIG. Then, as shown in FIG. 17A, when the laser beam is adjusted to a position where it is received by the first light receiving unit 48, the control unit 47 issues a command to the motor 45, as shown in FIG. 17B. The first shielding plate 43 is rotated to open the target mounting hole. Thereby, the operator can attach the rail member 5 to the correct position. That is, the rail member 5 can be attached at the same height as the attachment position to the first support column 1.

  Next, the operator attaches the rail member 5 to the fourth support column 4 in the same manner as the attachment of the rail member 5 to the third support column 3. That is, the light emitting switch 46 provided in the second unit 40 is pressed, and a laser beam is emitted from the third light emitting unit 49 to check the height. Subsequent operations are the same as in the case of the rail member 5 to the third support column 3, and thus detailed description thereof is omitted.

  By the above operation, the pair of rail members 5 can be attached to the rack 100 without being inclined in the front-rear direction and in a state where the heights are matched on the left and right. By using the mounting jig 1, for example, the rail member 5 can be easily mounted in a place where many racks are arranged. That is, when many racks are arranged, an operator's moving distance also becomes long and it becomes difficult to grasp | ascertain the exact attachment position of a rail member. Even in such a case, even if there is only one worker, the rail member mounting operation can be completed accurately and quickly.

  The characteristics of the mounting jig 1 are summarized as follows. That is, the mounting jig is detachable with respect to the rail mounting portion serving as a reference of the rack, and a launching unit including a launching unit that launches a detection medium toward another rail mounting portion adjacent to the reference rail mounting portion. Is provided. The 1st unit 20 provided with the 1st light emission part 25 and the 2nd light emission part 26, and the 2nd unit 40 provided with the 3rd light emission part 49 are equivalent to a launch unit. In addition, an installation permission unit that performs installation permission is provided. The second unit 40 including the first shielding plate 43, the third unit 60 including the second shielding plate 63, and the fourth unit 80 including the third shielding plate 83 correspond to an attachment permission unit. The attachment permission unit is detachable from other rail attachment parts, and includes a detection part that detects arrival of a detection medium emitted from the emission part. The attachment permission unit includes an attachment permission portion that permits attachment of a rail member to the other rail attachment portion when the detection portion detects a detection medium.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications, within the scope of the gist of the present invention described in the claims, It can be changed.
