Nothing corresponding to the sliding door installation space 52 is formed. The fork 11 of the first stacker crane 6 is configured to protrude toward the one shelf 4a at the stroke S1 and protrude toward the other shelf 4b at the stroke S2. Similarly, the fork 11 of the No. 3 stacker crane 6 is configured to protrude toward the one shelf 4f at the stroke S1 and protrude toward the other shelf 4e at the stroke S2. The stroke S1 is set longer than the stroke S2 by an amount corresponding to the sliding door installation space 52.

Hereinafter, the operation of the above configuration will be described.
For example, of the two types of articles 2a and 2b, those that do not require special handling are designated as general goods 2a, and those that require handling are designated as special goods 2b (for example, dangerous goods, deleterious substances, etc.) To do. In principle, the general article 2 a is stored in each storage space 16 of the general storage unit 14, and the special article 2 b is stored in each storage space 16 of the special storage unit 15.

  For example, when unloading the special article 2b from one shelf 4a of the first unit, the worker first turns on the unloading key 38 on the operation panel 32 of the first unit as shown in the flowcharts of FIGS. Step-1). Thereby, the delivery mode is displayed on the setting screen 35 (step-2). Next, the operator presses the numeric keypad 39 and inputs the shelf number corresponding to the storage space 16 in which the target special article 2b is stored (step-3), and then turns on the set key 40 (step). -4). Thus, the shelf number is displayed on the setting screen 35 (step-5).

  When the shelf number input in step-5 is that of the special storage unit 15 (step-6), a password input screen 42 as shown in FIG. 5B is displayed on the liquid crystal display unit 36 (step-6). -7). Next, the operator presses the numeric keypad 39, inputs his / her personal identification number (step-8), and then turns on the set key 40 (step-9). Then, the entered password number is compared with the previously registered password number (step -10), and if both match (step 11), the speaker 44 announces the content “Please open the sliding door”. (Step-12).

  Thereby, the operator moves to one opening / closing operation part 31a, unlocks the locking device of the fence body 18, and pulls the sliding door 22 to the fully open position A as shown in FIG. At this time, the announcement from the speaker 44 as described above can prevent an erroneous operation such that the worker leaves the door while the sliding door 22 is closed, and can prevent the user from forgetting to open the sliding door 22 at the time of leaving.

  Then, by opening the sliding door 22 to the fully open position A as described above, the open side detection means 25 is turned on, and it is detected that the sliding door 22 has been opened to the fully open position A (step -13). Thereafter, when the operator turns on the operation key 41 of the operation panel 32 (step-14), the operating device 43 is operated (step-15). As a result, the stacker crane 6 of No. 1 travels on the travel path 7, the loading platform 10 moves up and down, the fork 11 moves out and out, and the special article 2 b is transferred from the specific storage space 16 of the special storage unit 15 to the stacker crane. 6 is taken out, and is further transferred onto the load receiving platform 28 from the stacker crane 6 side.

  As a result, the presence detection means 46 is turned on, and it is detected that the special article 2b is placed on the receiving platform 28 (step -16). Thereafter, as shown in FIG. 1, the operator pushes the sliding door 22 to the fully closed position B and locks it in one of the opening / closing operation portions 31 a. As a result, the closed side detection means 26 is turned on, and it is detected that the sliding door 22 has been closed to the fully closed position B (step -17), and the history of the special article 2b that has been delivered (shipping time, personal identification number, operator name). , Product name, lot number, quantity, shelf number) are recorded in the history management unit 50 (step-18). And an operator carries out the special article 2b on the said receiving stand 28 using a forklift etc.

  If the operator forgets to close the sliding door 22 in Step-17, the closing side detection means 26 remains off. In this state, the operator uses a forklift or the like to perform a special operation on the load receiving table 28. When the article 2b is lifted in order to carry it out, the stock detection means 46 is switched from on to off (step -18), and the speaker 44 is activated to issue an alarm (step -19). Thereby, the operator notices that the sliding door 22 has been forgotten to be closed, and reliably closes the sliding door 22.

  Further, when the special article 2b is delivered as described above, only when the sliding door 22 is fully opened in the step-13, the stacker crane 6 is operated in the step-15, and the sliding door 22 is activated in the step-13. If it remains closed, the stacker crane 6 will not operate. Thereby, when the fork 11 of the stacker crane 6 enters the storage space 16 of the special storage unit 15, it is possible to prevent a malfunction such as the fork 11 colliding with the sliding door 22 that is closed.

  Further, when the special article 2b is delivered as described above, if the input password and the password registered in advance do not match in the step-11, the delivery mode and the shelf are set on the setting screen 35. Since the number is erased (step -20), the stacker crane 6 does not operate and the delivery is impossible. Thereby, it is possible to prevent an outsider from operating the stacker crane 6 without permission and taking out the special article 2 b from the storage space 16 of the special storage unit 15.

  ◎ Also, when unloading the general article 2a from one shelf 4a or the other shelf 4b of the first unit, in step-6, the input shelf number is not that of the special storage unit 15, but the general storage unit 14 It will be a thing. Then, it is determined whether the closed side detection means 26 is on (step-21). When the sliding door 22 is closed to the fully closed position B, the closed-side detection means 26 is turned on, and then the operator turns on the operation key 41 of the operation panel 32 (step -22), thereby operating the actuator 43. Is operated (step -23). As a result, the stacker crane 6 of the first unit travels on the travel route 7, the loading platform 10 moves up and down, the fork 11 moves in and out, and the general article 2 a is stored in the general storage section of one shelf 4 a or the other shelf 4 b. 14 is taken out from the specific storage space 16 to the stacker crane 6 side, is further transferred from the stacker crane 6 side onto the load receiving platform 28, and is discharged from the load receiving platform 28 using a forklift or the like.

  Further, when the general article 2a is delivered as described above, if the sliding door 22 is open in Step-21, the closing side detection means 26 is turned off and the speaker 44 indicates that “Please close the sliding door”. Announcement is played (step -24).

  Therefore, when the sliding door 22 is fully closed, the stacker crane 6 is operated and the general article 2a can be discharged. However, when the sliding door 22 is opened, the stacker crane 6 is not operated and the general article 2a is discharged. I can't. That is, the delivery of the general article 2a is performed in a state where the sliding door 22 is fully closed, thereby preventing the problem that the special article 2b is taken away from the special storage unit 15 during the delivery of the general article 2a. it can.

  For example, when the special article 2b is stored in the first machine, the worker places the special article 2b on the cargo receiving table 28 using a forklift or the like. Then, the worker turns on the warehousing key 37 of the operation panel 32 of the first unit (step-25). Thereby, as shown in the flowchart of FIG. 11, the warehousing mode is displayed on the setting screen 35 (step-26). Next, the operator presses the numeric keypad 39, inputs the shelf number corresponding to the storage space 16 that is the storage destination of the special article 2b (step-27), and then turns on the set key 40 (step-28). ). As a result, the shelf number is displayed on the setting screen 35 (step-29).

  If the shelf number input in step -27 is that of the special storage unit 15 (step-30), a password input screen 42 as shown in FIG. 5B is displayed on the liquid crystal display unit 36 (step 30). -31). Next, the operator presses the numeric key 39, inputs his / her personal identification number (step-32), and then turns on the set key 40 (step-33). Then, the input password number is compared with the previously registered password number (step-34), and if both match (step-35), the speaker 44 displays "sliding door" as shown in the flowchart of FIG. Please announce "Please open" (Step-36).

  Thereby, the operator moves to one opening / closing operation part 31a, unlocks the locking device of the fence body 18, and pulls the sliding door 22 to the fully open position A as shown in FIG. At this time, the announcement from the speaker 44 as described above can prevent an erroneous operation such that the operator enters the warehouse with the sliding door 22 closed, and can prevent the operator from forgetting to open the sliding door 22 at the time of warehousing.

  Then, by opening the sliding door 22 to the fully open position A as described above, the open side detection means 25 is turned on, and it is detected that the sliding door 22 has been opened to the fully open position A (step-37). Thereafter, when the operator turns on the operation key 41 of the operation panel 32 (step-38), the operating device 43 is operated (step-39). As a result, the stacker crane 6 of Unit 1 travels on the travel path 7, the loading platform 10 moves up and down, the fork 11 moves in and out, and the special article 2 b is scooped from the loading platform 28 toward the stacker crane 6 side. Furthermore, the goods are stored in the specific storage space 16 of the special storage unit 15 of the shelf 4a from the stacker crane 6 side. Then, the history (incoming time, worker name, product name, lot number, quantity, shelf number) of the received special article 2b is recorded in the history management unit 50 (step -40).

  After the completion of warehousing, the operator pushes the sliding door 22 to the fully closed position B and locks it in one of the opening / closing operation portions 31a as shown in FIG. Thereby, the closed side detection means 26 is turned on, and it is detected that the sliding door 22 is closed to the fully closed position B (step -41). Further, when the operator forgets to close the sliding door 22 in Step-41, the closing side detection means 26 remains off, and an announcement of "Please close the sliding door" is sent from the speaker 44 (Step- 42). Thereby, the operator notices that the sliding door 22 has been forgotten to be closed, and reliably closes the sliding door 22.

  In addition, when the special article 2b is received as described above, the stacker crane 6 is operated at Step-39 only when the sliding door 22 is fully opened at Step-37. If it remains closed, the stacker crane 6 will not operate. Thereby, when the fork 11 of the stacker crane 6 enters the storage space 16 of the special storage unit 15, it is possible to prevent malfunction such as the fork 11 and the special article 2b colliding with the sliding door 22 which is closed.

  Further, when the special article 2b is received as described above, if the input password and the password registered in advance do not match in step -35, the storage mode and the shelf are set on the setting screen 35. Since the number is deleted (step -43), the stacker crane 6 is not operated and the storage is impossible. Thereby, it is possible to prevent an outsider from operating the stacker crane 6 without permission to enter the special article 2 b into the storage space 16 of the special storage unit 15.

  In addition, when the general article 2a is stored in the first machine, the input shelf number is not that of the special storage unit 15 but that of the general storage unit 14 in Step-30. Then, it is determined whether the closed side detection means 26 is on (step -44). When the sliding door 22 is closed to the fully closed position B, the closed-side detection means 26 is turned on, and then the operator turns on the operation key 41 of the operation panel 32 (step-45), thereby operating the actuator 43. Is operated (step-46). As a result, the stacker crane 6 of Unit 1 travels on the travel path 7, the loading platform 10 moves up and down, the fork 11 moves in and out, and the general article 2 a is scooped from the loading platform 28 toward the stacker crane 6 side. Further, the stacker crane 6 side enters the specific storage space 16 of the general storage section 14 of the one shelf 4a or the other shelf 4b.

  Further, when the general article 2a is received as described above, if the sliding door 22 is open in step -44, the closing side detection means 26 is turned off and the speaker 44 indicates that "Please close the sliding door". Announcement is played (step-47).

  Therefore, when the sliding door 22 is fully closed, the stacker crane 6 is operated to receive the general article 2a. However, when the sliding door 22 is opened, the stacker crane 6 is not operated and the general article 2a is stored. I can't. Therefore, the general article 2a is stored in a state where the sliding door 22 is fully closed, thereby preventing the special article 2b from being taken away from the special storage unit 15 during the general article 2a storage. it can.

  As described above, in the first unit, the special article 2 b is stored in the storage space 16 of the special storage unit 15, and the special door 2 is closed by closing the sliding door 22 except when entering and leaving the special storage unit 15. Since the part 15 is surrounded by the fence body 18 and is cut off from the outside, an outsider cannot take the special article 2b from the special storage part 15 of the shelf 4a without permission, and the special article 2b is prevented from being stolen. Security measures can be taken.

  In addition, the operator can manually open and close the sliding door 22 in one opening / closing operation portion 31a. As shown in FIG. 1 and FIG. 2, the one opening / closing operation part 31 a and the load receiving table 28 are located on the opposite sides with respect to one end part of the traveling path 5. When the articles 2a and 2b are transferred between the stacker crane 6 that has traveled to the load receiving base 28, the safety of the operator in the one opening / closing operation portion 31a is ensured. Further, when the articles 2a and 2b are carried into and out of the load receiving table 28 using a forklift or the like, the sliding door 22 does not interfere with the forklift.

  Also, as shown in FIGS. 10 and 12, since the history of the special article 2b received / extracted in steps -18 and 40 is recorded and managed, the contents of the entry / exit operation can be easily checked later. Can do.

  Further, as shown by the solid line in FIG. 8, when the articles 2a and 2b are loaded into and unloaded from the one shelf 4a, the fork 11 of the stacker crane 6 projects into the storage space 16 of the one shelf 4a in the stroke S1, As shown by the phantom line in FIG. 8, when the article 2a is loaded into and unloaded from the other shelf 4b, the fork 11 of the stacker clean 6 protrudes into the storage space 16 of the other shelf 4b in the stroke S2. Thereby, the storage position of the articles 2a and 2b stored in each storage space 16 can be unified at the same position in the one shelf 4a and the other shelf 4b in the depth direction of the shelves 4a and 4b.

  The above is the case where the general article 2a and the special article 2b are stored / extracted with respect to the No. 1 machine. However, since the entry / exit is performed similarly for the No. 3 machine, the security measures for preventing theft of the special article 2b. Can be taken.
