And a wheel guide 12 provided at 11B.

  Each of the mounting surface portions 11A and 11B has a planar mounting surface 14 positioned on the same horizontal surface. The mounting surface portions 11A and 11B extend along the X-axis direction, and are juxtaposed at a predetermined distance (a distance corresponding to the distance between the wheels 202 in the Y-axis direction) in the Y-axis direction. The mounting surface portions 11A and 11B are fixed to the frame 15.

  The wheel guide 12 guides the rolling carriage 200 to be carried in and out, and corrects the rolling carriage 200 in order to suppress unintended movement of the rolling carriage 200. The wheel guide 12 is provided from one end to the other end of the mounting surface portion 11B. The wheel guides 12 have a pair of plate-like members erected on the placement surface 11B so as to be parallel to each other and to be aligned in the Y-axis direction. The wheel guide 12 cooperates with the mounting surface 14 to form a groove. The width of the groove is set to be slightly wider than the width of the wheel 202, and is set to such a width that the wheel 202 can not freely turn. The wheel guide 12 regulates the turning of the wheel 202 positioned therein, and maintains the orientation of the wheel 202 in the transfer direction (X-axis direction).

  The wheel guide 12 is divided into a plurality of parts, and includes a first wheel receiving portion 16, a second wheel receiving portion 17 and a guide rail 18. The first wheel receiving portion 16 is provided at one end in the X-axis direction in the mounting surface portion 11B. The second wheel receiving portion 17 is provided at the other end in the X-axis direction in the mounting surface portion 11B. The first wheel receiving portion 16 and the second wheel receiving portion 17 are fixed to the frame 15. The wheels 202 of the loaded rolling carriage 200 are positioned in the groove portions of the first wheel receiving portion 16 and the second wheel receiving portion 17, respectively.

  The height of the first wheel receiving portion 16 is not particularly limited, but, for example, is set higher than the height for lifting the rolling carriage 200 by the transfer device 124. The height of the second wheel receiving portion 17 is not particularly limited, but, for example, is set to be lower than the height for lifting the rolling carriage 200 by the transfer device 124. The tip end portions of the first wheel receiving portion 16 and the second wheel receiving portion 17 on the outer side in the X-axis direction are formed in a tapered shape so that the groove width becomes wider toward the outer side (see FIG. 5). The wheel guides 12 hold the wheels 202 of the rolling carriage 200 in the automated warehouse 100.

  As shown in FIG. 8, a fixing block 19 for positioning the wheel 202 of the mounted rolling carriage 200 is provided on the mounting surface portion 11B. The fixing block 19 here is disposed at a position corresponding to the inside of the groove portion of the first wheel receiving portion 16. The fixing block 19 functions as a stopper that regulates rolling of the wheel 202. The fixed block 19 has a wedge shape and is disposed in front of and behind the wheel 202. The fixed block 19 is set to allow, for example, a looseness of about 5 mm. The height of the fixed block 19 is set to be lower than the height for lifting the rolling carriage 200 by the transfer device 124.

  As shown in FIGS. 6, 7 and 9, the guide rail 18 is disposed between the first wheel receiving portion 16 and the second wheel receiving portion 17 in the mounting surface portion 11B, and along the X axis direction. To extend. The upper portion of the guide rail 18 is formed in a tapered shape so as to increase its groove width as it goes upward (see FIG. 9). Thereby, when the rolling carriage 200 is transferred, even when the direction of the wheel 202 is deviated from the transfer direction, the direction of the wheel 202 can be adjusted along the transfer direction.

  Here, the guide rail 18 is configured to be capable of moving up and down so that a projection length (hereinafter, simply referred to as “projection length”) which is a length in the vertical direction projecting upward from the mounting surface 14 changes. The guide rails 18 can be raised and lowered such that the projection length is smaller when the rolling carriage 200 is carried by the operator than when the rolling carriage 200 is transferred by the transfer device 124.

  Specifically, the guide rail 18 is supported by the frame 15 via the elevation guide 21 and the drive device (drive unit) 22. The elevating guide 21 supports the guide rails 18 and guides the elevation of the guide rails 18 with respect to the frame 15. For example, the lifting guides 21 are attached to both ends of the guide rail 18 in the X direction. The drive device 22 includes a motor (not shown) and an eccentric cam (not shown) connected to the rotation shaft of the motor, and supports the guide rail 18 so as to be able to move up and down via the eccentric cam. The guide rail 18 vertically moves relative to the frame 15 between the raised position and the lowered position each time the motor of the drive device 22 is rotated by a fixed amount (for example, 180 °).

  For example, when the guide rail 18 is at the lowered position, when the motor is rotated by a fixed amount in the drive device 22 to rotate the eccentric cam, the guide rail 18 is guided by the elevating guide 21 to the top dead center position by the eccentric cam Ascend (lift). As a result, the guide rail 18 ascends to a raised position projecting with a first projecting length (for example, 100 mm) extending above the first wheel receiving portion 16 and the second wheel receiving portion 17.

  On the other hand, when the guide rail 18 is at the raised position, the motor is rotated by a fixed amount in the drive device 22 to rotate the eccentric cam, and the guide rail 18 is guided by the elevating guide 21 to the bottom dead center position by the eccentric cam Go down. As a result, the guide rail 18 is lowered to a lowered position where it protrudes with a second protruding length (for example, 30 mm) below the first wheel receiving portion 16 and the second wheel receiving portion 17. The second protrusion length is smaller than the first protrusion length, in other words, the first protrusion length is larger than the second protrusion length.

  The drive unit 22 is connected to a control unit 23 that controls the operation of the drive unit 22. The control unit 23 raises and lowers the guide rail 18 so that the projection length becomes smaller when the operator carries the rolling carriage 200 in and out than when the rolling carriage 200 is transferred by the transfer device 124. Specifically, the control unit 23 determines whether the guide rail 18 is to be positioned at the raised position or the lowered position based on, for example, a request from a host controller (such as an automatic warehouse controller). Then, the control unit 23 starts the operation of the drive device 22 based on the position of the guide rail 18 detected by the photoelectric sensor 24, for example, in order to position the guide rail 18 in either the determined ascending position or descending position. / Or stop. In the illustrated example, a photoelectric sensor 24 is provided on the frame 15, and the position of the guide rail 18 is detected by detecting any one of the upper end and the lower end of a predetermined portion of the guide rail 18 by the photoelectric sensor 24.

  Alternatively, a guide lifting switch (lifting operation unit) may be provided for the operator to move the guide rail 18 up and down. In this case, the control unit 23 operates the drive device 22 according to the operation of the guide lifting switch. The control is performed, and the guide rail 18 is moved up and down to either the raised position or the lowered position according to the operation of the guide lifting switch.

  In the above, at least the station ST (the warehousing station ST1 or the delivery station ST2), the transfer device 124, the guide rail 18, the drive device 22, and the control unit 23 constitute the transfer system 1. That is, the automated warehouse 100 includes the transfer system 1. In addition, each configuration or each element with which the automatic warehouse 100 is provided can be grasped as being provided with the transfer system 1.

  Next, operations performed in the transfer system 1 and the automatic warehouse 100 will be described. In the following description, at the time of loading and unloading the rolling carriage 200 at the station ST by the operator and at the time of transferring and loading the rolling carriage 200 placed at the station ST by the transfer device 124 Each is illustrated.

[When unloading]
First, based on, for example, the transfer condition of the stacker crane 102 and / or the placement condition of the rolling carriage 200 at the station ST, the host controller requests the control unit 23 to lower the guide rail 18 to the lowered position. Is output. Alternatively, the operator lowers the guide rail 18 via the guide lifting switch, and the guide lifting switch outputs a request for lowering the guide rail 18 to the control unit 23. In addition, the condition or state of the stacker crane 102 and / or the station ST can be detected by, for example, a camera, a light shielding sensor, a limit switch or the like.

  In response to the request, the control unit 23 controls the operation of the drive device 22 and projects the guide rail 18 in the raised position with a second projection length that projects upward from the mounting surface 14 to the extent that the wheel 202 can be guided. To the lowered position (see FIGS. 6 and 9A). In this state, the operator carries the rolling carriage 200 directly to the station ST without placing it on a dedicated pallet or the like, and places the rolling carriage 200 on the placement surface portions 11A and 11B of the station ST. Each wheel 202 of the rolling carriage 200 enters from the second wheel receiving portion 17 in the wheel guide 12, reaches the first wheel receiving portion 16 while being guided by the guide rail 18, and is positioned by the fixing block 19. In addition, since the X direction outer side of the 2nd wheel receiving part 17 is expanded at the time of carrying in of the rolling truck 200, even if the wheel 202 faces in any direction, the direction of the said wheel 202 Can be adjusted along the transfer direction.

[When transferring by transfer device]
First, based on, for example, the transfer condition of the stacker crane 102 and / or the placement condition of the rolling carriage 200 at the station ST, the host controller requests the control unit 23 to raise the guide rail 18 to the raised position. Is output. Alternatively, the operator raises the guide rail 18 via the guide lifting switch, and the guide lifting switch outputs a request for lifting the guide rail 18 to the control unit 23.

  In response to the request, the control unit 23 controls the operation of the drive device 22 and projects the guide rail 18 in the lowered position upward from the mounting surface 14 with the first projection length that can reliably restrict the turning of the wheel 202. To an elevated position (see FIGS. 7 and 9 (b)). In this state, the slide fork 124a of the transfer device 124 extends in the space below the rolling carriage 200, and the rolling carriage 200 is lifted so as to cover the bottom of the rolling carriage 200. Lifting of the rolling carriage 200 may be realized by the lifting platform 123 of the stacker crane 102, or may be realized by a lifting structure provided separately by the transfer device 124. At this time, since the outer side in the X direction of the first wheel receiving portion 16 is tapered so as to expand, a slight positional deviation of the transfer device 124 can be tolerated. Thereafter, the transfer device 124 transfers the rolling carriage 200 toward the shelf 31 with the rolling carriage 200 lifted.

  As mentioned above, in the transfer system 1 of this embodiment, the guide rail 18 which regulates turning of the wheel 202 of the rolling carriage 200 is provided at the station ST where the rolling carriage 200 can be carried in and out. The guide rail 18 is configured to be movable up and down so that the projection length from the mounting surface 14 changes. Therefore, at the time of carrying in and out of the rolling carriage 200 by the operator, for example, the guide rail 18 is lowered to make the projecting length smaller, thereby suppressing the guide rail 18 from being an obstacle in the carrying in and out work. Can easily carry 200 in and out. When the rolling carriage 200 is transferred by the transfer device 124, the rolling carriage 200 is lifted by the transfer device 124, for example, by raising the guide rail 18 and securing a sufficient projecting length. Also, the wheel 202 can be reliably guided by the guide rails 18, and the rolling carriage 200 can be reliably transferred. That is, it is possible to facilitate transfer of the rolling carriage 200 by the operator and to reliably transfer the rolling carriage 200 by the transfer device 124.

  In the transfer system 1, the guide rails 18 can be moved up and down so that the protruding length of the rolling carriage 200 by the operator is smaller than when the rolling carriage 200 is transferred by the transfer device 124. There is. Thus, the loading and unloading of the rolling carriage 200 by the operator can be facilitated, and the above-described operation and effect of reliably transferring the rolling carriage 200 by the transfer device 124 can be suitably exhibited.

  The transfer system 1 includes a drive unit 22 that raises and lowers the guide rail 18 and a control unit 23 that controls the operation of the drive unit 22. According to this configuration, by controlling the operation of the driving device 22 by the control unit 23 as described above, the loading and unloading of the rolling carriage 200 by the worker is performed more than when the rolling carriage 200 is transferred by the transfer device 124. At the same time, the guide rail 18 can be moved up and down to reduce the projection length.

  In the transfer system 1, the transfer device 124 has a slide fork 124a for lifting the rolling carriage 200 so as to cover the bottom of the rolling carriage 200, and a guide member 126 provided on the slide fork 124a. . Even when the loading position of the rolling carriage 200 by the operator is deviated from the rolling stand on-board setting area R by the guide member 126 of the slide fork 124a, for example, the rolling stand 200 It can be corrected to be placed on R.

  The automated warehouse 100 includes the transfer system 1, a stacker crane 102 traveling along a track 51, and racks 101A and 101B on both sides via the track 51. A storage station ST1 is provided at the lowermost level of the rack 101A, and a delivery station ST2 is provided at the lowermost level of the rack 101B. As described above, by using the lowermost stages of the racks 101A and 101B as the stations ST1 and ST2, it is possible to easily carry in and out a large number of rolling carriages 200. By positioning the loading station ST1 and the unloading station ST2 opposite to each other via the track 51, the direction of the wheel 202 is maintained without changing the orientation of the rolling carriage 200 (moving the rolling carriage 200) Can be easy).

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. The configuration, the number, the shape, and the like of each element are not limited to the configuration, the number, the shape, and the like in the above-described embodiment, and can be changed as appropriate.
