Can be detected.

On the other hand, the container 70 of the present embodiment forms a long rectangular box-shaped storage portion 71 as shown in FIGS. 5 to 7, and has a sole portion 72 on the lower surface of the bottom wall.
A handle 73, a pair of groove connecting pieces 75, and a tenon connecting piece 76 are formed on both front and rear end faces 71a, 71a of the box-shaped storage portion 71, respectively.

In the handle 73, a recess 73a that opens downward is formed in the center of the lower portion of the end surface 71a of the box-shaped storage portion 71 (see FIG. 7).
The hook 41 of the hook sliding member 40 is inserted into the recess 73a from below and engaged with the handle 73.

  The groove connecting piece 75 protrudes vertically from the upper and lower sides to the left side of the end surface 71a of the box-shaped storage portion 71, and the upper groove connecting piece 75 protrudes from the end surface 71a and the tip is bent downward in an L shape. The groove connecting piece 75 on the side protrudes from the end surface 71a and the tip is bent upward in an L shape, and a dovetail groove 75a oriented in the horizontal direction along the end surface is formed therebetween.

  On the other hand, the tenon connecting piece 76 protrudes from the middle height of the upper and lower groove connecting pieces 75, 75 on the right side of the end surface 71a, and its tip is bent up and down to engage with the dovetail groove 75a. 76a is formed.

  A handle 73, a groove connecting piece 75, and a tenon connecting piece 76 are formed in the same manner on both end faces 71a and 71a of the container 70. The groove connecting piece 75 on the left and the tenon connecting piece 76 on the right on the one end face 71a. When arranged, the other end surface 71a is also configured such that the groove connecting piece 75 is arranged on the left and the tenon connecting piece 76 is arranged on the right, and there is no distinction between front and rear.

  When connecting the containers 70, the end surface 71a of one container 70 and the end surface 71a of the other container 70 are shifted to the left and right at the same height, and the other tenon connecting piece is inserted into the dovetail groove 75a of one groove connecting piece 75. When the ant tenon 76a faces each other with an interval facing it, and both are moved horizontally so as to correct the left / right displacement, the ant tenon 76a is inserted into the ant groove 75a as shown in FIG. The dovetails 75a of the pair of groove connecting pieces 75 of one container 70, the dovetails 76a of the tenon connecting pieces 76, the dovetails 76a of the tenon connecting pieces 76 of the other container 70, and the dovetails of the groove connecting piece 75 The grooves 75a are engaged with each other in a loosely fitted state and connected to each other.

  Therefore, the containers 70 in a state in which the dovetail groove 75a of the groove connecting piece 75 and the dovetail 76a of the tenon connecting piece 76 are connected to each other are connected to each other even if the connecting portion is relatively moved up and down. It is difficult to remove the ant tenon 76a from the groove 75a.

  When the container 70 is stored in a fixed position in each shelf booth 3 of the storage shelf 3, the container 70 stored on the front door side is connected to the front end surface 71a as shown in FIG. 4 and FIG. Accordingly, the groove connecting piece 75, the tenon connecting piece 76 and the handle 73 on the same end surface 71a are projected from the shelf front surface (container receiving member 5) to the passage side.

The article storage device 1 and the container 70 have the above-described structure, and a schematic block diagram of a carry-in / out control system by the stacker crane 6 is shown in FIG.
A transport machine control panel 51 connected to a central control panel (server) 50 and controlled in an integrated manner is controlled by a control device 52 which is a computer. The control device 52 is connected to the travel stop detector via an input interface 53. Detection signals are input from 17a, 17b, the lift stop detector 19, and the hook travel position detectors 48a, 48b, 48c, signal processed and output to the speed control unit 54, and the speed control unit 54 uses the travel drive device. The motor 21, the motor of the lift drive device 22, the hook travel motor 47, and the hook up / down motor 37 are driven and controlled.

  The present carry-in / out control system also performs automatic container restoration control, which will be described later, and a detection signal from the container fixed position detector 10 is also input to the transporter control panel 51.

In the overall control panel (server) 50, the presence status of the container is grasped in association with the number of each container for all the shelf booths 3 of the storage shelf 2, and is stored as a location table.
The occupancy status data of the container in each shelf booth 3 is stored as a two-digit number “**”.
The first place in the container presence status data “**” indicates the presence situation of the container on the back side of the shelf booth, and the tenth place indicates the presence status of the container on the front side of the shelf booth.

That is, “0” is indicated if the seat is vacant, and “1” or “2” if the seat is present.
“1” in the case of being present indicates a case where the present container is designated to be carried out, and “2” indicates a case in which the present container being present is not designated to be carried out.

  For example, if the container presence status data is “21” for a certain booth, the container exists on both the back side and the front side, and the container on the back side is designated to be carried out. This is the case where a container exists on both the front side and the frontage side, and the frontage side container is designated to be carried out. If "10", the container exists only on the frontage side, and the same container is designated to be carried out. is there.

Note that it is impossible for a container to exist only on the back side of a shelf space if it is normal.
Therefore, even if the container presence status data is “20”, it cannot be “02” or “01”.

The procedure for carrying out the container by the control system as described above will be described with reference to the flowchart of FIG.
The state of each process in the container unloading operation is shown in FIGS. 12 and 13, and this figure is also referred to.

  First, when the number of the container to be carried out is designated (step 1), the location table stored in the overall control panel (server) 50 is searched from the container number, and the shelf booth 3 storing the carry-out designated container is stored. Are extracted (step 2).

The location can be represented by a row-b series-c stage-**, and the last ** is the container occupancy status data "**", and between the a-column-b series-c stage shelf booths. When there is a carry-out designated container 70 on the far side, it is “21”, and when there is a carry-out designated container 70 on the frontage side, it is “12” or “10”.
“12” is when the container 70 is connected to the back side, and “10” is when there is no container 70 on the back side and there is a container 70 to be carried out only on the front side.

In the next step 3, this location data is set in the transport machine control panel 51.
Next, at step 4, the transport machine control panel 51 controls the travel drive device 21 based on the first travel stop detector 17 a and the travel stop iron piece 16 to control the stacker crane 6 in the first row of b rows of b rows. It moves to the stop position, controls the elevator drive device 22 based on the elevator stop detector 19 and the elevator stop iron piece 18, moves the loading platform 8 up and down to the c-stage shelf booth 3, and the shelf in which the designated container is stored The left and right container receiving members 5 and 5 of the booth 3 and the left and right slide plates 31 and 31 of the loading platform 8 coincide with the same horizontal plane, and the container 70 can be transferred (see FIGS. 4 and 12 (1)). .

  In step 5, when the hook 41 is run at a medium height and stopped when the hook engagement / disengagement position detector 48a on the shelf booth side to be carried out detects the hook 41, as shown in FIG. Since one hook 41 is positioned directly below the recess 73a by the handle 73 on the end face of the container 70, when the hook 41 is lifted together with the hook guide rail 33 by driving the hook up / down motor 37, the hook 41 is moved to the shelf front side. It is inserted into the recess 73a of the container 70 and engages with the handle 73 (see FIG. 12 (2)).

  Next, in step 6, it is determined whether or not the container presence status data is “10”, that is, whether there is no container on the back side between the shelves and whether or not a container only on the front side is designated to be carried out. If “10” indicates that the container 70 located only on the frontage side is specified to be carried out, the process proceeds to step 7 and the container 70 is located on both the back side and the frontage side instead of “10” and is connected to each other. Goes to step 9.

  When the routine proceeds to step 7, the hook 41 that engages the handle 73 of the front-portion container 70 designated for carrying out is run by the hook running motor 47, and the neutral position detector 48b on the side opposite to the shelf booth 3 is moved to the hook 41. Is detected, the unloading designated container 70 is transferred from the shelf booth 3 to the loading platform 8 of the stacker crane 6 and positioned at the center of the loading platform 8.

  Then, in the next step 8, the container occupancy status data at the location of the shelves is updated to “00”, then the process jumps to step 17, the stacker crane 6 is run, the loading platform 8 is moved to the station, and is carried out. The designated container 70 is transferred to the station and carried out.

  If it is determined in step 6 that there is a container 70 on both the back side and the front side instead of “10” and the process proceeds to step 9, the hook 41 that engages the handle 73 of the front side container 70 is connected to the hook travel motor 47. Is stopped when the connecting / disengaging position detector 48c on the opposite side of the shelf booth 3 detects the hook 41.

  Then, as shown in FIG. 12 (3), the shelf front container 70 and the back container 70 connected thereto slide on the container receiving members 5, 5, and the shelf front container 70 is connected to the container receiving member 5. , 5 are moved onto the slide plates 31 and 31 of the loading platform 8 and slid to be moved from the shelf booth 3 to the loading platform 8 side, and the container 70 on the back side is aligned with the front end surface 71a of the front shelf. The groove connecting piece 75, the tenon connecting piece 76 and the handle 73 of the end surface 71a are protruded from the shelf front surface (container receiving member 5) to the passage side and are arranged at fixed positions on the shelf front side.

  In the next step 10, the travel drive device 21 is travel-controlled to the second travel stop position where the second travel stop detector 17 b adjacent to the first travel stop detector 17 a detects the travel stop iron piece 16, and the stacker crane 6. Is slightly moved, the loading platform 8 moves horizontally together with the transferred container 70, and the groove connecting piece 75 and the tenon connecting piece 76 are disengaged as shown in FIG. Is disconnected.

  In the next step 11, the hook 41 that engages the handle 73 of the container 70 placed on the loading platform 8 is run by the hook running motor 47, and the neutral position detector 48 b on the side opposite to the shelf booth 3 moves the hook 41. When it is detected, the container 70 is stopped and the container 70 is positioned at the center of the loading platform 8 (see FIG. 13 (5)).

  Then, in the next step 12, it is determined whether or not the container presence status data is “12”, that is, whether or not the front-side container 70 transferred to the loading platform 8 is a container designated to be carried out, If the container 70 on the loading platform 8 is designated as “12”, the process proceeds to step 13, while if the container 70 that is located on the far side instead of “12” is designated to be carried out, the process proceeds to step 14. .

  When the container presence status data is “12” and the container 70 on the loading platform 8 is designated to be carried out, when the process proceeds to step 13, the container presence status data is updated to “20” and the process proceeds to step 17.

  That is, since the container 70 placed on the loading platform 8 is designated to be carried out, in step 17, the stacker crane 6 is moved as it is, the loading platform 8 is moved to the station, and the designated loading container 70 is transferred to the station. Then carry it out.

On the other hand, if it is determined in step 12 that the container 70 that is not in the container presence status data “12” is specified to be carried out, and the process proceeds to step 14, the container presence status data is set to “10”. Update to
In other words, the container 70 that is currently moved to the front side of the shelf booth is designated to be carried out, and the container presence status data in which the container 70 does not exist on the back side is used.

In step 15, the stacker crane 6 on which the undesignated container 70 is mounted on the loading platform 8 is run, and the loading platform 8 is moved to an empty location.
Next, in step 16, the undesignated container 70 is stored in the shelf booth 3 in the empty location, and the process returns to step 4.

  Thus, when returning to step 4, the container presence status data is “10”, so that the designated unloading container 70 remaining in the shelf booth 3 through the routes of steps 4, 5, 6, 7, 8, and 17 is obtained. Is transferred to the loading platform 8 of the stacker crane 6 and conveyed to the station to be carried out.

Next, the procedure for carrying in the container will be described according to the flowchart of FIG. 14 with reference to the states of the respective steps of the carry-in work of FIGS.
First, the container 70 to be loaded is mounted on the loading platform 8 of the stacker crane 6 and the number of the loaded container 70 is designated (step 21). Then, the container is loaded from the location table stored in the overall control panel (server) 50. The location of the shelf booth 3 to be searched is searched, and the container number is associated and stored in the location table. (Step 22).

  For the shelf booth 3 to be searched, the container presence status data is “20” or “00”, “20” is the shelf booth where the container exists only on the frontage side, and “00” indicates the container It is a non-existent shelf booth.

In the next step 23, the location data is set in the transport machine control panel 51.
In the next step 24, it is determined whether or not the container presence status data is “20”, that is, whether or not there is a container on the front side between the shelves. Proceed to 25. If "20", proceed to step 28.

  When the container 70 does not exist in the shelf booth 3 and the process proceeds to step 25, the travel drive device is controlled based on the first travel stop detector 17a and the travel stop iron piece 16 to control the stacker crane 6 in the shelf booth 3. The container 70 is moved to the first traveling stop position of the rack, and the lifting / lowering drive device 22 is controlled based on the lifting / lowering stop detector 19 and the lifting / lowering stop iron piece 18 so that the loading platform 8 faces the shelf booth 3. Make it possible.

  Then, in step 26, when the hook 41 is driven at a medium height by pushing the container 70 on the loading platform 8 and moved to the hook engaging / disengaging position detector 48a, the container 70 on the loading platform 8 is placed in the shelf booth 3. To the front position.

Next, in step 27, the container presence status data is updated to “20”, that is, to indicate that the container 70 exists only on the shelf front side in the shelf booth 3, and the flow jumps to step 33 to display the neutral position. The detector 48b moves the hook 41 to a neutral position where the hook 41 is detected.

  In step 24, it is determined that there is a container 70 on the front side of the shelf booth 3 (container status data is “20”), and when the process proceeds to step 28, the stacker crane 6 is connected to the shelf booth of the shelf booth 3. And the elevator drive device 22 is controlled based on the elevator stop detector 19 and the elevator stop iron piece 18 to adjust the loading platform 8 to the height of the shelf booth 3.

In the state shown in FIG. 15 (1), the loading platform 8 is shifted in the left-right direction at the same height with respect to the shelf booth 3.
That is, the container 70 on the loading platform 8 is opposed to the container 70 existing at the front side fixed position of the shelf booth 3 while being shifted left and right.

In the next step 29, the hook 41 that has been in the neutral position is slightly run, and stops when the connection / disengagement position detector 48c detects the hook 41 (see FIG. 15 (2)).
Then, as shown in FIG. 15 (2), the container 70 on the loading platform 8 causes the pair of groove coupling pieces 75 and the tenon coupling pieces 76 to protrude from the loading platform 8, so that the pair of groove couplings of the container 70 on the shelf front 3 side. This is a position where the piece 75 and the tenon connecting piece 76 can be fitted.

  Then, by moving the stacker crane 6 to the first travel stop position in step 30, as shown in FIG. 15 (3), the pair of groove connecting pieces 75 and tenon connecting pieces 76 of the container 70 on the side of the shelf front 3 are moved to the loading platform. The pair of tenon connecting pieces 76 and the groove connecting pieces 75 of the 8-side container 70 are fitted and connected to each other.

  In the next step 31, when the hook 41 is moved at a medium height by pushing the container 70 on the loading platform 8 and moved to the hook engaging / disengaging position detector 48 a, as shown in FIG. The existing container 70 is transferred to the shelf booth 3, reaches the frontage-side fixed position, and is simultaneously pushed by the container 70, the container 70 that is on the shelf frontage side moves to the back side of the shelf booth 3.

  In step 32, the container occupancy status data is updated to “22”, that is, the shelf booth 3 is indicated to have a container on both the front side and the back side, and the process jumps to step 33 to display the neutral position. The detector 48b moves the hook 41 to a neutral position where it detects the hook 41 (see FIG. 16 (5)).

  As described above, the container loading / unloading work can be efficiently performed with simple control by the container presence status data in the location table stored in the overall control panel (server) 50.

  The connecting means of the container 70 according to the present embodiment includes a groove connecting piece 75 in which a dovetail groove 75a is formed in the both ends of the container in the horizontal direction along the end face, and a dovetail that can engage with the groove connecting piece 75. A pair of tenon connecting pieces 76 each having a tenon 76a formed thereon, and the containers move relatively horizontally with their end faces opposed to each other, so that a pair of groove connecting pieces 75 on the end face of the container 70 The tenon connecting piece 76 is engaged with and connected to the pair of tenon connecting pieces 76 and the groove connecting piece 75 on the opposite end surfaces of the other containers 70, so that the mutually connected containers are being carried in or out. Thus, even if the connecting part is lifted and relative vertical movement occurs, disconnection is avoided as much as possible.

  In addition, since the container 70 in the shelf booth 3 is restricted to move left and right by the pair of left and right container receiving members 5 and 5, there is no relative movement in the horizontal direction between the connected containers 70 and 70. The release of the connection by this is avoided.

  As described above, once the groove connecting piece 75 and the tenon connecting piece 76 are engaged and the containers 70 and 70 are connected to each other, the connection is rarely released during the carrying-in or carrying-out. When the connection is released, the container 70 is illegally arranged at an illegal position other than the front-end fixed position of the shelf booth 3 and cannot be taken out by the hook 41.

In addition, when the container 70 on the loading platform 8 side is connected and stored to the container 70 in the shelf booth 3 at the time of carry-in, if it is stored without being connected, The container 70 cannot be removed by the hook 41.
Further, when a shake such as an earthquake acts on the storage shelf 2 and the container 70 that has been in the fixed position on the front side shifts to an illegal position in the back, the hook 41 cannot be engaged with the handle 73 and cannot be removed.

That is, when there is one container 70 in the shelf booth 3, if the container 70 exists at an illegal position other than the shelf front side fixed position, it cannot be taken out by the hook 41.
Therefore, in the past, the operator manually repaired, but when the shelf where the container 70 is illegally placed is at a high position, the worker corrects the container in the illegal position to the frontage side fixed position. This is dangerous and time consuming.

Therefore, the transport machine control panel 51 according to the present embodiment controls the carry-in / out work, and also performs the control of the automatic repair work for repairing the container 70 that is illegally arranged in the shelf booth 3 to the front-side fixed position. .
In this automatic repair work, a repair container 80 that is used exclusively for the repair work is used.

As shown in FIGS. 17 to 19, the repair container 80 has a long rectangular box-shaped storage portion 81 of the main body and a sole portion 82 of the bottom surface of the bottom wall having substantially the same shape as the normal container 70. is doing.
On the end surface of the end wall 81a of the box-shaped storage part 81, a handle 83 is formed at the same place as the normal container 70.

  In the end wall 81a of the repair container 80, one large rectangular opening 81b and two small upper and lower portions are provided at positions opposed to the groove connecting piece 75 and the tenon connecting piece 76 that are formed to protrude from the end surface 71a of the normal container 70, respectively. The tenon engagement pieces 85, 85 that are formed with rectangular openings 81c, 81c and that can be connected to the groove connecting piece 75 from one large rectangular opening 81b protrude from the two small rectangular openings 81c, 81c. The pieces 86 and 86 protrude.

  As shown in FIG. 20, the upper and lower ten-piece tenon engagement pieces 85 and 85 are formed so that one side portions 85b and 85b of the plate material bent in a crank shape are outward along the upper and lower edges of the rectangular opening 81b. Protruding and having distal end portions 85c and 85c bent at an angle somewhat smaller than a right angle in the opening direction, the proximal end side portions 85a and 85a projecting inward from the end wall 81a are connected to the inner surface of the end wall 81a. It is attached to hinges 91, 91 provided between them and is supported so as to be swingable.

The hinges 91, 91 are provided with torsion springs 92, 92, and the tenon engagement pieces 85, 85 are urged by the torsion springs 92, 92 in the direction in which the end portions 85 c, 85 c are opened from each other, and tenon engagement is performed. The crank bent portions of the pieces 85 and 85 are in contact with the opening end portion of the rectangular opening 81b, and the one side portions 85b and 85b are maintained in a posture protruding substantially in parallel as shown in FIG.
The upper and lower mortise engaging pieces 85 are provided on one side of the rectangular opening 81b that does not overlap with each other.

  Accordingly, when the repair container 80 approaches the normal container 70 and the end surfaces of the normal container 70 come into contact with each other, the tenon engagement pieces 85 and 85 facing the groove connecting pieces 75 and 75 of the normal container 70 approach each other, and FIG. As shown in (2), the slanted tip portions 85c and 85c of the tenon engaging pieces 85 and 85 are in contact with the end portions of the upper and lower connecting pieces 75 and 75, and are engaged with the tenon against the torsion springs 92 and 92. The pieces 85 and 85 are swung in the direction in which the end portions 85c and 85c are closed.

  Further, by approaching, the tenon engaging pieces 85, 85 close to each other and overlap with each other in a side view, the leading end portions 85c, 85c penetrate between the upper and lower connecting pieces 75, 75 and enter the dovetail groove 75a. 20 (3), the torsion springs 92 and 92 open in the dovetail groove 75a, and the tenon engaging pieces 85 and 85 engage with the connecting pieces 75 and 75, respectively.

  On the other hand, the groove engaging pieces 86, 86 protruding from the upper and lower two small rectangular openings 81c, 81c of the end wall 81a of the repair container 80 are one side portion of a plate material bent into a crank shape as shown in FIG. 86b and 86b are projected outwards along the edges of the rectangular openings 81c and 81c, respectively, and the tips 86c and 86c are bent at an angle somewhat smaller than a right angle in the direction of closing each other, and the end wall 81a Proximal side portions 86a and 86a projecting inward are attached to hinges 93 and 93 provided between the inner surface of the end wall 81a and supported in a swingable manner.

The hinges 93, 93 are provided with torsion springs 94, 94. The groove engaging pieces 86, 86 are urged by the torsion springs 94, 94 in the direction in which the end portions 86 c, 86 c are closed to each other to engage the grooves. The crank bent portions of the pieces 86, 86 abut against the opening ends of the rectangular openings 81c, 81c, and the one side portions 86b, 86b are maintained in a posture protruding substantially in parallel as shown in FIG.
The upper and lower groove engaging pieces 86, 86 are positioned one above the other.

  Therefore, when the repairing container 80 approaches the normal container 70 and faces each other, the groove engaging pieces 86 and 86 facing the tenon connecting piece 76 projecting in a T shape of the normal container 70 are formed. As shown in FIG. 21 (2), the inclined end portions 86c, 86c of the groove engaging pieces 86, 86 are in contact with the upper and lower ends of the tenon mortises 76a of the tenon connecting pieces 76 and are connected to the torsion springs 92, 92. Accordingly, the groove engaging pieces 86, 86 are swung in the direction in which the tip portions 86c, 86c are opened.

  Further, by approaching, the tip end portions 85c and 85c of the groove engaging pieces 86 and 86 that open to each other get over the ant tenon 76a, and the back of the ant tenon 76a by the torsion springs 92 and 92 as shown in FIG. The groove engaging pieces 86, 86 engage with the tenon connecting piece 76.

Using the repair container 80 provided with the tenon engagement pieces 85 and 85 and the groove engagement pieces 86 and 86 on the both end walls 81a and 81a as described above, the container 70 arranged at an illegal position other than the frontage side fixed position. Correct the position to return to the home position.
Whether or not the container 70 is illegally arranged is determined based on a location table stored in the overall control panel (server) 50 and a detection signal of the container fixed position detector 10.

  That is, if there is a shelf booth 3 in which the container fixed position detector 10 does not detect the container 70 among the shelf booths 3 of the location where the container presence status data of the location table indicates “20”, the shelf booth 3 It can be determined that the container 70 is not located at the frontage-side fixed position but is located at an illegal position.

  Hereinafter, the procedure for repairing an illegally arranged container will be described according to the flowchart of FIG. 22 with reference to the state of each process of the repair work of FIGS.

  First, in step 1, as described above, it is determined whether or not the container fixed position detector 10 detects the container 70 in the shelf booth 3 of the location where the container presence status data of the location table indicates “20”, that is, It is determined whether or not the container 70 is illegally arranged. If the container 70 is detected, it is determined that the container 70 is correctly arranged at the frontage-side fixed position, and the monitoring is repeated by repeating Step 1.

If it is determined that the container 70 is improperly arranged, the process proceeds to step 52. If the carrying-in / out operation is in the middle, the process is awaited and the process proceeds to step 53.
In step 53, the stacker crane 6 travels to the shelf booth 3 in which the restoration container 80 is stored, the loading platform 8 moves, and in the next step 54, the restoration container 80 is transferred to the loading platform 8.

Note that the repair container 80 is always on standby in a predetermined specific shelf booth 3.
Unlike the other normal shelf booths 3, the specific shelf booth 3 is provided with a stopper at a predetermined intermediate position in the depth direction of the shelf so that the repair container 80 hits the stopper and is positioned at the frontage side fixed position. It has become.
The location of this specific shelf is registered in the overall control panel 50.

When the restoration container 80 is mounted on the loading platform 8, in step 55, the stacker crane 6 travels to the shelves at the location where the containers 70 are illegally arranged and stops at the first travel stop position.
Next, in step 56, the loading platform 8 is moved to the shelf stage of the shelf booth 3 where the containers 70 are illegally arranged.

  Then, as shown in FIG. 23 (1), the loading platform 8 is positioned so that the container can be transferred to the shelf booth 3, and the repair container 80 on the loading platform 8 is placed in the container 70 improperly arranged in the shelf booth 3. Opposite.

  In the next step 57, the hook 41 engaged with the handle 83 of the repair container 80 is moved to transfer the repair container 80 to the shelf booth 3, during which the repair container 80 is illegally placed. Approaching the container 70, the groove engaging pieces 86, 86 and the tenon engaging pieces 85, 85 on the repair container 80 side engage with the tenon connecting piece 76 and the connecting pieces 75, 75 on the container 70 side, respectively. The repair container 80 is connected to the container 70.

  The torsion springs 92 and 94 that swing and energize the groove engaging pieces 86 and 86 and the tenon engaging pieces 85 and 85 have a relatively small spring force, and the groove engaging pieces 86 and 86 and the tenon engaging pieces 85 and 85 However, when the tenon connecting piece 76 and the connecting pieces 75, 75 on the container 70 side are brought into contact with each other, the container 70 can be engaged without being moved.

However, even if the hook 41 cannot be engaged due to this contact, the hook 41 travels to the hook engagement / disengagement position, so that the container 70 is pushed by the repair container 80 without being engaged, moves to the back, and hits the stopper 9 and stops. Therefore, the restoration container 80 is strongly pressed by the stopped container 70, and the groove engaging pieces 86 and 86 and the tenon engaging pieces 85 and 85 are securely connected to the tenon connecting piece 76 and the connecting pieces 75 and 75 on the container 70 side. (See FIG. 23 (2)).
Therefore, as shown in FIG. 23 (2), the repair container 80 is located at the front-side fixed position, and the container 70 that was previously at the incorrect position is connected to the repair container 80 on the far side, Hereinafter, a normal carry-out operation may be executed.

That is, in the next step 58, the hook 41 that engages with the handle 83 of the repair container 80 is caused to travel by the hook travel motor 47, and the connection engagement / disengagement position detector 48b opposite to the shelf booth 3 detects the hook 41. Stop at the connecting / disconnecting position.
As shown in FIG. 23 (3), the restoration container 80 is transferred to the loading platform 8 side by the traveling of the hook 41, and the container 70 connected to the restoration container 80 moves to the frontage side fixed position.

  Then, in the next step 59, the travel drive device 21 is travel-controlled to the second travel stop position where the second travel stop detector 17b adjacent to the first travel stop detector 17a detects the travel stop iron piece 16 to control the stacker crane. When the vehicle 6 is moved slightly, the loading platform 8 moves horizontally together with the transferred restoration container 80, and as shown in FIG. 24 (4), the groove engaging pieces 86, 86 on the restoration container 80 side are tenoned. The joining pieces 85, 85 come out of the tenon connecting piece 76 and the connecting pieces 75, 75 on the container 70 side to disengage, and the connection between the repair container 80 and the container 70 is released.

  In the next step 60, the hook 41 engaged with the handle 83 of the restoration container 80 transferred to the loading platform 8 is run by the hook running motor 47, and the neutral position detector 48c opposite to the shelf booth 3 is hooked. When 41 is detected, it is stopped and the repairing container 80 is positioned at the center of the loading platform 8 (see FIG. 24 (5)).

  In step 61, the stacker crane 6 is moved, and the loading platform 8 is moved to the predetermined shelf booth 3. In the next step 62, the repair container 80 on the loading platform 8 is stored in the shelf booth 3, and illegal The repair work of the arranged container is finished.

As described above, the illegally arranged container can be automatically corrected to the fixed position by using the repair container.
Therefore, the worker does not have to perform repair work for the container position, which is sometimes dangerous work, and can be repaired in less time.

  The connecting operation between the normal container 70 and the repairing container 80 is only required to contact the repairing container 80 with the normal container 70, and the work is easier than the connection between the normal containers 70 and 70. Since the connection release operation with the repair container 80 is the same as the connection release operation between the normal containers 70 and 70, there is no need for special complicated control and the control is simple.

  The state in which the groove engaging pieces 86 and 86 and the tenon engaging pieces 85 and 85 on the repair container 80 side are engaged with the tenon connecting piece 76 and the connecting pieces 75 and 75 on the container 70 side is the normal container 70 and 70, respectively. The groove connection pieces 75 and the tenon connection pieces 76 are in the same state of engagement as each other, and the connection is not easily disconnected even if the connection portion is lifted.

  In the above embodiment, the container fixed position detector 10 is an example provided in each shelf booth 3. However, an example in which the container fixed position detector is provided in the loading platform 8 on the stacker crane 6 side will be described below. explain.

  As shown in FIG. 25, container fixed position detectors 100 and 100 are respectively arranged at positions lower than the slide plate 31 along the front and rear end surfaces of the loading platform 8, and the container fixed position detector 100 is a reflection type optical sensor. If there is a container 70 within a predetermined distance above, this can be detected.

  Therefore, when the container 70 is carried into and out of the shelf booth 3 and the loading platform 8 is opposed to the shelf booth, when the container 70 that should be in the frontage side fixed position is not detected by the container fixed position detector 100, It can be determined that the container 70 is illegally arranged.

As described above, since the illegal arrangement of the container 70 can be detected when the container 70 is carried in and out, the repair work for the illegally arranged container is performed before and after the carrying in and out.
That is, when the loading platform 8 of the stacker crane 6 is stopped in the shelf booth 3 instructed to carry in / out, or when the loading / unloading is completed, the container is repaired by the repair container 80.

  First, when the container fixed position detector 100 detects that there is no container 70 that should be in the frontage side fixed position when the loading platform 8 is loaded and stopped in the required shelf booth 3 by carrying-in work, The container 70 on the loading platform 8 is temporarily stored in an empty shelf, and a series of repair work (work from step 53 to step 62 in the flowchart shown in FIG. 22 in the above embodiment) is performed by the repair container 80. The container 70 that has been illegally arranged by execution is restored to a fixed position on the frontage side, and then the required container 70 is taken into the temporarily stored shelf booth 3, and the container 70 is carried into the required shelf booth 3.

  In addition, immediately after the required container 70 is transferred from the loading platform 8 and loaded into the shelf booth 3 where no container 70 exists, the container fixed position detector 100 indicates that there is no container 70 that should be in the fixed position on the front end side. Is detected immediately, a series of repair operations are immediately executed, and the illegally arranged container 70 is repaired to the frontage side home position.

  Next, when it is detected by the container fixed position detector 100 that there is no container 70 that should be in the frontage side fixed position when the loading platform 8 moves to the required shelf booth 3 and stops in the carry-out operation, immediately, A series of repair work is executed, and the illegally arranged container 70 is repaired to the frontage side fixed position, and then the repaired container 70 is carried out from the shelf booth 3.

  In addition, immediately after the container 70 on the frontage side is unloaded from the shelf frontage 3 where the containers 70 are stored on both the frontage side and the back side, there is no container 70 that should move to the frontage side and be in a fixed position. When detected by the fixed position detector 100, after the container 70 on the loading platform 8 is transported to the station, a series of repair operations are performed, and the illegally arranged container 70 in the shelf booth 3 is set to the front side fixed position. to repair.

  As described above, when it is detected that the container between the shelves is not in a fixed position, depending on the contents of the work instruction and the container seating status on the loading platform, if there is a preparatory work necessary to shift to the repair work, the preparatory work Then, after performing the repair work, if the initial loading / unloading work has not been performed, a series of work to perform the initial loading / unloading work is performed continuously. Therefore, wasted time can be minimized.

In addition, when it is detected that the container in the shelf booth is not in a fixed position at the end of the required loading / unloading work in the shelf booth, the repair work is not performed immediately, avoiding the busy hours of the stacker crane 6 and automatically It is also possible to start the repair work.
It is also possible for the operator to give an instruction to start the repair work.

The present restoration container 80 has a box-shaped storage unit 81 and functions as a container for storing and transporting articles. However, if the outer shape is the same as the normal container 70, the container 80 does not have a storage unit. It is not necessary to have the function as.
In addition, since the present restoration container 80 has a function as a container, the cost is high, but the restoration container 80 can be used as a normal container.

  In the above embodiment, two containers 70 can be connected and stored in the shelf booth 3 of the storage shelf 2, but more than two containers 70 are sequentially connected and stored. Even if possible, the present invention is applicable.
