  The elevating rail 133 is a long member that is attached over almost the entire length of the mast 128, and is a member that slidably engages with the elevating platform 125 and guides the elevating along the mast 128 of the elevating platform 125. In the case of the present embodiment, only one lifting rail 133 is attached to the mast 128 on the opposite side of the carriage 123. By limiting the number of lifting rails 133 to one, the mast 128 can be downsized and the entire conveying apparatus 102 can be downsized. In the case of the present embodiment, the width of the mast 128 (the length in the Y-axis direction) is equal to or smaller than the width of the storage unit 111 of the storage shelf 101. Therefore, the first transfer device 131 and the second transfer device 132 can be arranged so as to correspond to the storage units 111 existing on both sides of the one storage unit 111, and are very close to each other in the width direction. It is possible to transfer the luggage 200 to the two storage units 111 at the same time. Moreover, as the raising / lowering rail 133, the linear rail which comprises a linear guide can be listed, for example.

  The elevating platform 125 is a member that is guided by the mast 128 and moves up and down in the up-and-down direction. The elevating table 125 extends to both sides of the mast 128 in the traveling direction and is transferred to each of the both sides. It is a member to which the transfer device 132) is attached. In the case of the present embodiment, since the mast 128 is disposed in the vicinity of the storage shelf 101, the lifting platform 125 is arranged on one side of the mast 128 (this embodiment) in the transfer direction of the luggage 200 (X-axis direction in the figure). In this case, it is configured so as to project relatively long on the opposite side of the storage shelf 101.

  In addition, the lifting platform 125 includes a connection portion 135 and a lifting guide 136.

  A plurality of lifting guides 136 are members that are attached to the lifting platform 125 and slidably engage with the lifting rail 133. The lifting guide 136 is attached to a position where the lifting platform 125 balances in the traveling direction, for example, the central portion of the lifting platform 125 in the traveling direction. As a result, the lifting platform 125 can be lifted and lowered smoothly. In the case of the present embodiment, one piece is attached above and below the lifting platform 125 (main body). Thereby, the distance of the raising / lowering guide 136 which exists in an upper end and the raising / lowering guide 136 which exists in a lower end can be lengthened, and the raising / lowering of the raising / lowering stand 125 can be stabilized. In addition, by dispersing the lifting guide 136 above and below the lifting platform 125 (main body), it is possible to reduce the dead space at the upper end and lower end of the mast 128. In the case of the present embodiment, the lifting guide 136 is a linear guide that is slidably engaged with the lifting rail 133 that is a linear rail.

  The connection part 135 is a part which connects the suspension member 134 to the center part of the lifting platform 125 in the traveling direction. The connection method of the suspension member 134 by the connection part 135 is not particularly limited. For example, the suspension member 134 is sandwiched and connected, or the shaft is inserted into the hole of the suspension member 134. It can be illustrated.

  As in the present embodiment, since the lifting guide 136 and the connecting portion 135 are present at the center position of the same lifting platform 125 in the transport direction, the lifting platform 125 can be lifted and lowered in a stable state. Further, the elevating rail 133 constituting the linear guide is attached to the mast 128, and the suspending member 134 is an object (elevating platform 125, transfer object) that the suspending member 134 suspends from the elevating rail 133 (elevating guide 136).

The baggage 200 is transferred by pushing or pulling 200.

  As a result, two packages 200 can be transported at a time, and the packages 200 can be transferred in a wider range than the movable region of the mast 128. That is, the luggage 200 stored from one end to the other end of the storage shelf 101 in the traveling direction can be transferred, and dead space in the automatic warehouse 100 can be suppressed.

  Further, the balance with respect to the mast 128 is improved, and it is possible to reduce the shaking of the mast 128 with respect to the moving direction when the mast 128 is moved.

  In addition, since it is the structure which has arrange | positioned the 1st transfer apparatus 131 and the 2nd transfer apparatus 132 on the both sides of the one mast 128 in the traveling direction, respectively, the cart 123 is preferably long in the traveling direction. According to this, the horizontal guide member 121 and the guide member 127 can be engaged with each other at positions as far apart as possible and symmetrical with respect to the mast 128, and the mast 128 can be stably driven without shaking. Is possible. On the other hand, if the carriage 123 is too long, the movable region of the mast 128 is narrowed.

  From the above, the length of the carriage 123 is the length from the one end edge to the other end edge in the traveling direction of the carriage 123 of the structural member constituted by the lifting platform 125, the first transfer device 131, and the second transfer device 132. It is preferable that it is equivalent or less.

  Further, the transfer method of the transfer device is not particularly limited. For example, the load 200 is pushed or pulled using an arm to slide between the storage shelf 101 and the lifting platform 125. And the like, and the load 200 is lifted and moved by using a fork attached to the arm, and the load 200 is dropped and transferred.

  In the case of the present embodiment, the transport device 102 includes a first control panel 161 and a second control panel 162 at the portions of the lifting platform 125 that exist on both sides of the mast 128 in the traveling direction. The first control panel 161 and the second control panel 162 mainly supply power to the first transfer device 131 and the second transfer device 132, respectively, and also the first transfer device 131 and the second transfer device 132. It is the box which each accommodates the 1st electrical component for controlling each apparatus 132, and a 2nd electrical component (not shown).

  Examples of the first electrical component and the second electrical component include a motor driver that controls a motor provided in the transfer device, an I / O unit of a sensor group attached to the transfer device and the lifting platform 125, and the like. .

  As described above, by arranging the control panel in a well-balanced manner with respect to the lifting platform 125 and arranging the electrical components in a well-balanced manner, it is possible to move up and down with a good balance as a whole.

  FIG. 6 is a side view of the automatic warehouse with a part cut away.

  As shown in the figure, the automatic warehouse 100 includes a facing storage shelf 109 that is disposed to face the storage shelf 101. Similar to the storage shelf 101, the facing storage shelf 109 is a shelf to which the luggage 200 is transferred by a transfer device provided in the transport device 102, and the horizontal guide member 121 and the support column 122 are not disposed. A lot of luggage 200 can be stored.

On the other hand, the mast 128 of the automatic warehouse 100 extends to the lower side of the mounting base 301, and the vertical drive device 129 for raising and lowering the lifting platform 125 is disposed below the transporting device 102 and below the mounting base 301. ing. In addition, since the form of the power cable 191 disposed below the facing storage shelf 109 and below the mounting base 301 changes with the movement of the mast 128, the power cable 191 accompanying the change in the form of the power cable 191 In order to suppress damage, the cable protection chain 192 is held.

  According to the automatic warehouse 100 described above, the mast 128 is stored by making the area corresponding to a plurality of stages (two stages in the present embodiment) of the storage unit 111 of the storage shelf 101 into areas where the horizontal guide members 121 are arranged. It is possible to bring it closer to the shelf 101 side. Accordingly, even between the storage shelf 101 and the face-to-face storage shelf 109, a person can pass over the mast 128. Therefore, the automatic warehouse 100 can be easily maintained.

  In addition, since the carriage 123 traveling along the horizontal guide member 121 holds the mast 128 at the center of the mast 128 or in the vicinity thereof, the structural strength of the mast 128 is the length from the holding portion to the end. What is necessary is just to ensure the strength degree. That is, the structural strength can be set weaker than holding the end of the mast 128. Therefore, the mast 128 can be made relatively thin or thin, and the proportion of the mast 128 in the space between the storage shelf 101 and the facing storage shelf 109 can be reduced. In this respect as well, a person can easily pass over the mast 128 during maintenance.
