A detection unit 15, a tray designation detection unit 16 that detects the unlocked tray 4 and transmits the tray information to the control device 5, and a push pin 17 that constantly biases the tray 4 forward are provided.

  Reference numeral 18 denotes a frame material that supports the lock device 12, and the latch 13 is rotatably supported by a support shaft 19 that is provided on the frame material 18 and extends in the left-right direction of the housing 3 (FIG. 1). The latch 13 has an arm portion 20 extending forward, and an engaging claw 21 formed at the upper portion of the front end of the arm portion 20 is engaged with and disengaged from an engaging recess 22 on the bottom surface of the rear end of the tray 4. The main body of the solenoid 14 is attached to the frame member 18, and the pin 24 attached to the rod 23 of the solenoid 14 is engaged with the long hole 25 formed in the latch 13, so that the linear movement of the rod 23 is performed on the latch 13. It is converted into a rotational motion around the support shaft 19. When the rod 23 is extended, the engaging claw 21 of the latch 13 is engaged with the engaging concave portion 22 of the tray 4 to lock (lock) the tray 4, and when the rod 23 is retracted, the engaging claw 21 is engaged with the engaging concave portion. The tray 4 is removed from the tray 22 and unlocked (unlocked). The solenoid 14 is in a state where the rod 23 is extended when not energized, and in a state where the rod 23 is retracted when energized.

  A compression coil spring 30 is fitted on the rod 23. One end of the compression coil spring 30 is supported by the main body of the solenoid 14, and the other end is supported by a spring support piece 31 attached to the latch 13. The latch 13 is urged to rotate in the locking direction (counterclockwise direction in FIG. 3) by the urging force of the compression coil spring 30.

  The tray presence detection means 15 is configured as, for example, a tray presence detection switch 26 that has a movable switch and operates ON-OFF. The tray presence detection switch 26 is attached to the frame member 18 so that the movable switch pin 26 </ b> A faces the rear surface of the tray 4. The tray presence detection switch 26 is turned OFF when the movable switch pin 26A is extended, and is turned ON when the movable switch pin 26A is retracted, and transmits the ON signal to the control device 5 (FIG. 1). The stroke range of the movable switch pin 26A that maintains the ON state is set to be longer, and partly deviates from the stroke range of the movable switch pin 27A of the tray designation detection switch 27 that will be described later.

  The tray designation detection means 16 is configured as, for example, a tray designation detection switch 27 having a movable switch and performing an ON-OFF operation. The tray designation detection switch 27 is attached to the frame member 18 so that the movable switch pin 27A faces the rear surface of the tray 4. The tray designation detection switch 27 is turned off when the movable switch pin 27 </ b> A is extended, and is turned on when the movable switch pin 27 </ b> A is retracted to transmit the ON signal to the control device 5. The ON signal transmitted from the tray designation detection switch 27 is tray information for identifying each tray 4.

  The push pin 17 is supported by the frame member 18 and the reinforcing frame member 28 so as to be able to reciprocate, and the tip always presses the rear surface of the tray 4 by the elastic force of the compression coil spring 29.

  The tray management apparatus 1 is formed with a deepest push position of the tray 4 and a lock position of the tray 4 provided slightly before the deepest push position. The lock position is a position where the tray 4 is locked and stored by the lock device 12 in a normal state. As will be described later, when the user takes out the stored tray 4, the user can push the tray 4 once to the deepest pushing position to unlock the tray 4 and pull it forward. Further, when the tray 4 is returned, the tray 4 is once pushed to the innermost pushing position and then stored at the lock position.

"Action"
"Tray 4 removal procedure"
When the user inputs his / her ID information to the ID input means 6 and the input ID information matches the ID information previously registered in the control device 5 or the like, the front door 2 of the tray management device 1 is unlocked. Then, the door display lamp 8 is turned on. Next, when the user presses the push button 7, the front door 2 is opened.

  In the tray 4, when the input ID information matches the ID information registered in the control device 5 or the like in advance, all the trays 4 that are permitted to the ID information, that is, that can be taken out, are unlocked. The tray display lamps 11 of all the trays 4 that can be taken out flash slowly. The “unlockable state” refers to a state before unlocking in which the latch 13 and the tray 4 can be disengaged as long as the manual removal operation described below is performed.

  FIG. 5A shows a state in which the removable tray 4 is still locked by the latch 13 and positioned at the lock position because the rod 14 is extended while the solenoid 14 is not energized. Specifically, the tray 4 is urged forward by the push pin 17 so that the rear edge of the engagement recess 22 is engaged with the rear end of the engagement claw 21 of the latch 13. A play dimension is formed between the front edge of the engagement recess 22 and the front end of the engagement claw 21. In this locked state, the movable switch pin 26A is pushed against the rear surface of the tray 4 and is slightly retracted, so that the tray load detection switch 26 is in the ON state, while the movable switch pin 27A is extended to The designation detection switch 27 is in an OFF state.

  When the user pushes the front side of the tray 4 rearward as a manual take-out operation from the state of FIG. 5A, and the tray 4 is positioned at the innermost push position, the movable switch pin 26A further degenerates and the tray is loaded. While the detection switch 26 is maintained in the ON state, the movable switch pin 27A is pushed against the rear surface of the tray 4 and retracts, and the tray designation detection switch 27 is turned on. When both switches are in the ON state, the control device 5 energizes the solenoid 14, whereby the rod 23 is retracted, the engaging claw 21 is disengaged from the engaging recess 22, and the tray 4 is unlocked (see FIG. 5 (b) state).

  The ON signal transmitted from the tray designation detection switch 27 when the tray designation detection switch 27 is turned on is tray information for specifying which tray 4 has been taken out of all the trays 4 that can be taken out. It is transmitted to the control device 5. That is, in conjunction with the manual removal operation of the tray 4, the tray 4 is unlocked and tray information is transmitted from the tray designation detection switch 27 to the control device 5. As described above, the control device 5 grasps and manages which tray 4 has been taken out. Then, from the locked state of FIG. 5A, that is, the state that the tray presence detection switch 26 is ON and the tray designation detection switch 27 is OFF, the tray presence detection switch 26 and the tray designation detection are detected as shown in FIG. By changing both the switches 27 to the ON state, it is grasped and managed by the control device 5 that the tray 4 has been unlocked.

  When the user takes out the tray 4, as shown in FIG. 5 (c), the movable switch pins 26A and 27A are both extended, so that the tray presence detection switch 26 and the tray designation detection switch 27 are both turned off. When both the tray presence detection switch 26 and the tray designation detection switch 27 are turned off, the solenoid 14 is in a non-energized state and the rod 23 is extended.

“Tray 4 return procedure”
As shown in FIG. 6 (a), the movable switch pins 26A and 27A are both extended so that the user can return the tray 4 when the tray load detection switch 26 and the tray designation detection switch 27 are both OFF. Is pushed, the lower end of the rear surface of the tray 4 hits the front end of the engaging claw 21 of the latch 13. A slight play dimension is set between the pin 24 attached to the rod 23 shown in FIG. 3 and the long hole 25 formed in the latch 13, and an inclined surface is formed above the engaging claw 21 of the latch 13. 32 is formed, and when the inclined surface 32 receives from the tray 4 a pressing force that exceeds the biasing force of the compression coil spring 30, there is play between the pin 24 and the long hole 25, so that the latch 13 is in the unlocking direction. Rotate around the support shaft 19 so as to escape, and the pushing of the tray 4 is continued. Due to the presence of the compression coil spring 30, the latch 13 rotates in the unlocking direction by a necessary minimum amount.

  As shown in FIG. 6B, when the tray 4 is pushed to the innermost pushing position, the engaging claw 21 is engaged with the engaging recess 22 by the urging force of the compression coil spring 30, thereby locking the tray 4. The When the movable switch pins 26A and 27A are both pushed against the rear surface of the tray 4 and retract, the tray presence detection switch 26 and the tray designation detection switch 27 are both turned on. Based on the ON signals transmitted from the tray presence detection switch 26 and the tray designation detection switch 27, the control device 5 grasps that the tray 4 has been returned.

  In the tray 4 take-out operation procedure, the ID information input by the ID input means 6 and the ID information previously registered in the control device 5 and the like match, and the tray presence detection switch 26 and the tray designation detection switch 27 are When both of them are turned on, the solenoid 14 is energized, the engaging claw 21 is removed from the engaging recess 22 and the tray 4 is unlocked. In the procedure for returning the tray 4, FIG. Since the tray 4 removal state in a), that is, the tray load detection switch 26 and the tray designation detection switch 27 are both OFF, the tray load detection switch 26 and the tray designation detection switch 27 are both OFF. When the tray stock detection switch 26 and the tray designation detection switch 27 are both turned on, the control device 5 returns the tray 4 It is determined that Rutoki not energized the solenoid 14.

  When the user stops pushing the tray 4 and releases it, the tray 4 moves slightly forward by the urging force of the push pin 17 and is locked in the locked position as shown in FIG. Stored. The tray presence detection switch 26 is maintained in the ON state, while the tray designation detection switch 27 is in the OFF state.

From the above, the state of both switches until the stored tray 4 is taken out and the tray 4 is stored again changes as follows.
(1) “Tray inventory detection switch 26: ON, tray designation detection switch 27: OFF” → (2) “Both switches are both ON” → (3) “Tray inventory detection switch 26: ON, tray designation detection switch 27: OFF ”→ (4)“ Both switches are both OFF ”→ (5) Tray inventory detection switch 26: ON, tray designation detection switch 27: OFF” → (6) “Both switches are both ON” → (7 ) “Tray inventory detection switch 26: ON, tray designation detection switch 27: OFF”
During the transition from (2) to (6), the return (locking) of the tray 4 is specified by the fact that (4) “Both switches are both OFF” is entered. From (6) to (2) The absence (unlocking) of the tray 4 is specified by the absence of it during the transition.

  As described above, the tray designation detection means 16 (tray designation detection switch 27) for detecting the unlocked tray 4 and transmitting the tray information is provided, and interlocked with the manual removal operation of the tray 4 in the unlockable state. If the tray 4 is unlocked and the tray information is transmitted from the tray designation detection means 16 (tray designation detection switch 27), the following effects can be obtained.

  If a tray number is assigned to the tray 4 and the user inputs the tray number to a number input device installed at a location away from the tray management device 1, the tray 4 can be unlocked. Assuming the system to take out, as a procedure to take out the tray 4, the user opens the front door 2, and (1) confirms the tray number of the tray 4 permitted to take out, (2) then moves to the number input device And enter the tray number. (3) Next, the procedure of returning to the tray management apparatus 1 again and performing the manual removal operation of the tray 4 is required, which increases the operation procedure and forces the user to move between the apparatuses. Even if the user stores the tray number in advance, the procedures (2) and (3) are necessary.

  On the other hand, according to the present invention, after the front door 2 is opened, the user performs the manual removal operation of the tray 4 directly in front of the tray management device 1 without any movement, so that the tray 4 can be removed. When the lock is performed and the tray information (for example, the tray number, the tray storage location number, etc.) that can specify which tray 4 is transmitted is transmitted, which tray 4 is to be manually ejected. As a result, the tray 4 can be taken out with a simple procedure. The transmitted tray information is stored in the control device 5 as a tray removal history for the purpose of managing which tray is the tray 4 on which the manual removal operation has been performed.

Also, the tray designation detection switch 27 that is turned ON / OFF by the movement of the tray 4 and the ON / OFF action that is activated by the movement of the tray 4 are set so that the operation range of the tray designation detection switch 27 and the ON-OFF is partially shifted. The tray presence detection switch 26 is provided, and the control unit (control device 5) specifies whether the tray 4 is unlocked or locked depending on the difference in the ON / OFF state of both switches. By adopting the configuration, for example, there is no need for sensors for specifying the moving direction (takeout direction or return direction) of the tray 4, and the tray 4 can be simply configured by using two general-purpose ON-OFF operation switches. It is possible to specify and manage the unlocked state and locked state of
The control unit for specifying whether the tray 4 is unlocked or locked is arranged outside the tray management device 1 as in the control device 5 of the present embodiment, It may be arranged inside.

  Further, a deepest pushing position of the tray 4 and a lock position of the tray 4 provided slightly before the deepest push position are formed. When the tray 4 is in the lock position, the tray load detection switch 26 is turned on. The tray designation detection switch 27 is turned off, both switches are turned on when the tray 4 is at the innermost pushing position, and both switches are turned off when the tray 4 is taken out. As a result, the installation setting of the tray designation detection switch 27 and the tray presence detection switch 26 is simplified, and the assembling property is improved.

  The preferred embodiment of the tray management apparatus has been described above, but the present invention is not limited to this, and various design changes can be made without departing from the spirit of the invention. For example, the ID input means may be provided in the tray management apparatus.
