Refer to Figure (E) 1. Then, carry in the upper part of the case support roller 1GB. When (or during) the stacker crane 103 and lifting platform 104 are activated, the hook! As the elevating member 108 descends so that the hook 10 is located below the bottom surface of the article storage case 112, the hook 110 is removed from the handle txt (see FIG. Until it is located below the opening of the handle 111 on the rear side of the case 112.

The moving body 107 moves backward, and then the elevating member 10B
is raised, and the hook 110 engages with the handle 111 (see FIGS. 8(G) and 8(H)).

When the longitudinal movement table 105 shifts forward by a shift amount,
As the movable body 107 moves forward, the article storage case 112 is pushed by the hook 110 to the loading/unloading station (see FIGS. After the elevating member 108 has descended to a position where it does not touch the bottom of the movable body 107, the movable body 107 moves slightly backward, so the hook 110 is removed from the handle lit.6Then, the back and forth movable base 105 is shifted backward by the shift amount ( (See Figure 8 (L)).

In this way, the article storage case 112 is carried out. In addition, due to the reverse operation, the case 111Wl shelf 102
The article storage case 112 is also stored in the storage case 112.

When pulling out the article storage case 112 stored in the case shelf 102 of the front rack 101 and carrying it out to the loading/unloading station (the path shown), the same operation as described above is performed, and the operation is reversed. Accordingly, the article storage case 112 is also stored in the case mounting 1102.

(Background of the Invention) In the conventional automated warehouse, as shown in FIG. The distance W between the front handle 111 and the front handle 112 (hereinafter referred to as one passage width W) was required to be a length expressed by the following formula.

W = L + 41 + 2 c + 2 dL is the length of the article storage case 112 excluding the thickness H of the handle 111 C is half the length of the horizontal plate 109 excluding the thickness of the hook 110 C is the frontmost or rearmost end The gap d between the hook 110 in position and the handle 111 of the article storage case 112 in the case mount 16102 is the thickness of the hook 110.In the face of rising land prices, the passage width W should be narrowed as much as possible to make effective use of land. After wondering if there was a way to do this, the inventor completed this invention.

This pusher 42 is configured to face the upper end of the operating lever 16 when the back-and-forth moving table 31 is positioned at a position where the case mounting shelf 2 is pulled out, and to push the operating lever 16 when the back-and-forth moving table 31 shifts. being done.

A case support member 48 consisting of a large number of rollers 47 is provided on the right vertical wall 33.
so that the case support surface and the conveyance surface 52 are flush with each other,
In addition, a case conveyor 49 is provided on the left vertical fi 33 so that the conveyance direction is oriented back and forth. This case conveyor 49 has a pair of pulleys 50 at the front and rear.
and an endless belt 51 that is passed around these pulleys 50. A width direction regulation guide 53 is provided at the upper end of the vertical @ 33 at an interval corresponding to the width of the case mounting shelf 2 .

The horizontal wall 32 of the back-and-forth movable table 31 is provided with guide rails 56 whose longitudinal direction is directed back and forth, and a movable body 57 is guided by these guide rails 56 so as to be movable back and forth. Rods 58 are erected, an elevating member 59 is guided by these rods 58 so as to be able to rise and fall freely, a horizontal plate 60 is provided on this elevating member 59, and a pair of hooks 61 are erected at the front and rear of this horizontal plate 60. The hook 61 is configured to engage the handle 7 of the case shelf 2 from below as the elevating member 59 rises.

The driving wheel I4 of the movable body 57 has right and left sets of wheels 65 rotatably provided at the front and rear of the horizontal wall 32, and the front set and the rear set are lined up left and right. One of these wheels 65 is a reversible motor 66
An endless chain 67 is connected to these wheels 65.

A shaft 68 is erected at one location of the endless chain 67, and this shaft 68 is fitted into a long hole 69 formed in the moving body 57 in the left-right direction and having a width approximately equal to the diameter of the shaft 68. A left-right sliding member 70 is provided at the upper end of 6B, and is provided so as to be movable left and right without relative movement in the front-back direction with respect to the movable body 57.A bracket 71 provided on this left-right sliding member 70 A roller 72 is rotatably fitted.

This roller 72 is adapted to fit into a recess 73 formed in the lower part of the elevating member 59, and this recess 73 has an inclined cam surface 74. With this configuration, when the shaft 68 is in the longitudinal movement section of the endless chain 67,
Since there is no relative movement between the shaft 68 (left-right sliding member 70) and the movable body 57, the movable body 57 is pulled by the shaft 68 by 1
It will move back and forth. On the other hand, when the shaft 68 is in the horizontal movement section of the endless chain 67 (including the part where it hangs on the wheel 65), the shaft 68 moves within the elongated hole 69, so that the roller 72 moves up the inclined cam surface 74. When the roller 72 moves down the inclined cam surface 74, the elevating member 59 is lowered. In short, by driving the endless chain 67, the movable body 57 and the elevating member 5
9 can be activated. In addition.

It goes without saying that the roller 72 may be simply a protrusion.

The power transmission device I77 that connects the movable body 57 and the case transport conveyor 49 by power has a movable rack 78 that is provided on the horizontal wall 32 so as to be movable back and forth and has a length that is approximately half of the length in the longitudinal direction. Protrusions 79 are provided at the front and rear ends of this movable rack 78, and the interval between these protrusions 79 is half the amount of longitudinal movement of a protrusion 80, which will be described later. A protrusion 80 located between these protrusions 79 is provided on the movable body 57. With this configuration, the movable rack 78 follows the movement of the movable body 57 only when the protrusion 80 hooks the protrusion 79 and moves, and when the protrusion 80 is located between the protrusions 79, the movable rack 78 does not move or move. The rack 78 does not follow the movement of the moving body 57 and is stopped. A pinion 81 that engages with the movable rack 78 is rotatably provided at the center of the vertical wall 33 in the front-rear direction via a rotating shaft 82, and a pulley 83 is fitted to the other end of the rotating shaft 82. A pulley 84 is connected to the shaft of the pulley 50 of the case conveyor 49 via an electromagnetic clutch 85. This electromagnetic clutch 8
5 is configured to be in an ON state when the moving body 57 moves backward after the article storage case 5 is drawn into the back-and-forth motion table 31. An endless belt 86 is passed around the pulleys 83 and 84. And pulley 83
, by adjusting the sizes of the pulleys 84, etc., when the electromagnetic clutch 85 is in the ON state, the moving body 57 is
While moving forward or backward, the endless bell 51 moves in a direction opposite to the moving direction of the moving body 57 by a belt moving amount to be described later. That is, the electromagnetic clutch 85 is in the ON state, and the protrusion 80 is in the moving rack 7
In other words, even if the electromagnetic clutch 85 is in the ON state before the protrusion 80 hits the protrusion 79, or when the electromagnetic clutch 85 is turned on after the protrusion 80 leaves the protrusion 79, Even in the OFF state, the belt can be accurately moved by a predetermined amount. Note that instead of the electromagnetic clutch 85, a protrusion 8 is provided on the elevating member 59.
0 is provided, and when the elevating member 59 descends, the protrusion 8
0 can be engaged with the protrusion 79, and the protrusion 80 cannot be engaged with the protrusion 78 when the elevating member 59 is raised. When the movable body 57 returns after being retracted, the movement may be transmitted to the case transport conveyor 49. Furthermore, the article storage case may be a pallet-like object.

(Effect of Example) Next, the operation of the warehouse according to the embodiment will be explained.

First, a case will be described in which the article storage case 5 stored in the case shelf 2 of the rear rack 1 is pulled out and carried out to the loading/unloading station 9.

The transport surface 52 of the case transport conveyor 49 is aligned with the upper support surface of the case storage shelf 2 in which the desired article storage case 5 is stored, and the horizontal center of the back-and-forth movable table 31 is aligned with the case storage shelf 2. The stuff car crane 22 and the lifting platform 24 are operated to match that of the above. Thereafter, the moving body 57, which was not at the rearmost position but at a slightly forward position, moves to the rearmost position. At this time, the elevating member 59 is in a lowered state, and the hook 61 is attached to the handle 7 on the front side of the desired article storage case 5.
(see Figure 6 (a)), and then
The back and forth movement table 31 is shifted slightly rearward so that the two rear hooks 61 are located directly below the opening 8 of the handle 7 (see Fig. 6).
(b)), that is, with this shift, the longitudinal center C2 of the longitudinal movable platform 31 changes to the longitudinal center C2 of the stuff car crane 22.
It will be located behind 1 by the shift amount. At this time, the operating lever 16 is pushed by the pusher 42,
Stopper 18 is pushed down.

Next, when the elevating member 59 is pushed up by the roller 72 due to the drive of the endless chain 67, the hook 61 engages with the handle 7 (see FIG. 6(c)). As it moves forward, the article storage case 5 is pulled by the hook 61, pulled out from the case mounting shelf 2, and transferred to the case conveyor 49 and the case support member 48. The article storage case 5 is completely transferred to the case conveyor 49. When transferred to the case support member 48, in this state, the rear edge of the rear hook 61 when the movable body 57 is located at the rearmost position is aligned with the rear edge of the rear handle 7 ( At that time, the electromagnetic clutch 85 is in the OFF state 1, so the movement of the movable body 57 is not transmitted to the case conveyor 49 via the power transmission device 77. The moving platform 31 shifts forward by the shift amount, and the longitudinal center C2 of the longitudinal moving platform 31 becomes the longitudinal center CI of the stacker crane 22.
(see Figure 6 (E)), at this time, the stopper! 8 returns to the original state. Thereafter, the transport surface 52 of the case transport conveyor 49 is adjusted so that the case receiver of the loading/unloading station 9 is the same as the upper surface of the surface, and the back-and-forth moving table 31 is
When the stacker crane 22 and the lifting platform 24 are operated (or during the operation), the hook 61 is attached to the article storage case 5 so that the horizontal center of the case holder coincides with that of the surface of the case holder.
The elevating member 59 is lowered so that it is located below the bottom surface of the frame.

The lever 61 is removed from the handle 7 (see FIG. 6(f)) 6. Then, the movable body 57 moves rearward. At this time, the electromagnetic clutch 85 is in the ON state, and the endless belt 51 is moved by the belt movement amount (
21+d-H) (where H is the thickness of the handle 7).

The article storage case 5 also moves accordingly, and the moving body 57
When is located at the rearmost position, in that state, the front hook 61 is located below the opening 8 of the rear handle 7. Thereafter, the electromagnetic clutch 85 is turned off. As is clear from this explanation, due to the operation of the case conveyor 49, the passage width w (L+
2jL+2C+d+H), belt 1? This means that the conduit can be narrowed by the width corresponding to the maximum distance.

W-w = (L + 4 views + 2c + 2d) - (L + 2 views + 2c
+d+H)z21+d-H After that, the elevating member 59 rises, and the hook 61 moves to the handle 7.
(See Figure 6 (g) and (h)).

Next, when the back-and-forth movable table 31 is shifted forward by the shift amount, the movable body 57 moves forward, and the article storage case 5 is pushed by the hook 61 to the loading/unloading stage 9 (see Fig. 6). ) (see ), then hook 6
After the elevating member 59 descends to a position where the hook 1 does not touch the bottom of the article storage case 5, the movable body 57 moves slightly backward, so the hook 61 comes off the handle 7. (See Figure 6 (L)).

In this way, the article storage case 5 is carried out.

In addition, the article storage case 5 is also stored on the case shelf 2 by the reverse operation.

When the article storage case 5 stored in the case shelf 2 of the front rack l is pulled out and carried out to the loading/unloading stage 9, the same operation as described above is performed, and the reverse operation is performed. The article storage case 5 is also stored on the case shelf 2.

(Effects of the Invention) As described above, according to the present invention, at the time of carrying out, the case transport conveyor moves the article storage case thereon by a predetermined amount toward the carrying out side, thereby narrowing the width of one passage, thereby making effective use of land. It is possible to aim for Further, since the case conveyor is linked to the movement of the moving body by the power transmission device, an independent drive device for the case conveyor is not required.
