Description

[Detailed Description of the Invention] [Industrial Application Field] This invention enables unattended delivery without involving a third party when a delivery person delivers a delivery item to a resident, even when the resident is absent. This invention relates to a locking device for a shared locker for storing delivered items.

[Conventional technology]

Traditionally, when a delivery person delivers a package to a resident,
When the resident was absent, the work was entrusted to a caretaker or neighbor.

[Problem that the invention seeks to solve]

By the way, recently, in order to streamline management work and save labor, the number of janitors has been reduced, or reception work at entrances etc. has been abolished and left unmanned, and only remote monitoring has been performed. I have learned not to do this.

Therefore, there was a problem in that the delivery person took the delivered item home, confirmed the date the resident was in the room, and then delivered it again, which was troublesome and time consuming.

This invention was made in order to solve the above-mentioned problems, and it enables delivery items to be reliably delivered to the resident even when the resident is absent, prevents unauthorized use of lockers, and furthermore ,
To provide a locking device for a shared locker for storing delivered items, which prevents the creation of a duplicate locker key.

[Means for solving problems]

A locking device is provided in the housing of the locker to enable locking with the locker key only while the electronic key is inserted into the key reading device, and the locker key is inserted into a cylinder lock of the locking device. An engaging protrusion is provided on the opposite side of the key insertion hole that rotates when the locker key is operated, and a sickle for engaging the locker door is removably fitted into this engaging protrusion, while the door is opened. The second door has a means for preventing rotation of the sickle by locking it when the sickle is in the open state and not engaged with the door, and for releasing the lock of the sickle only when it is excited by energization. A solenoid No. 1 is provided, which locks into the engagement hole formed on the outer circumferential side of the cylinder lock to prevent removal from the lock device, and releases the lock from the cylinder lock only when it is energized by electricity. A second solenoid having means for energizing each solenoid is provided in parallel with the first solenoid, and a push button switch and a reed switch that are turned on when the door is closed are provided for each solenoid. They are connected in series.

[Effect]

In this invention, when locking the locker door, the electronic key is inserted into the key reader, the door is closed, the reed switch is turned on, and the button switch is then pressed to energize the first solenoid. After unlocking the sickle, rotate the lock key. On the other hand, when removing the cylinder lock from the lock device, close the door and turn on the reed switch while inserting the electronic key into the key reader, then press the push button switch to energize the second solenoid.

Next, the operation will be explained.

First, in Fig. 1 a to d, the sickle 4 is located at the position indicated by the broken line in Fig. 1 a, d (the position indicated by the solid line in Fig. 1 c)
1, the engagement plate 14 of the first solenoid 12 in FIG. Therefore, even if an attempt is made to lock the door C by rotating the locker key _KL inserted into the key insertion hole 2, the door _C cannot be locked because the locker key KL does not rotate.

Next, when the delivery person stores the delivered goods in the case B of the locker A and closes and locks the door _C , in FIG. When inserted, the electronic key K _E is read by the key reading device 31, and the read signal is input to the CPU 32 for verification. Then, if the verification is correct, a lock signal is sent,
input to inverter INV ₁ of interface 34, and set the level of the output side of inverter INV ₁ to “0”.
to make the excitation coil EC ₁₂ ready for operation.

Next, when the delivery person stores the delivered goods, closes the door C, and presses the push button switch 10 shown in FIGS. Since it is on, the current from power source E is as shown in Figure 2.
Power supply E → push button switch S ₁₀ → reed switch S ₁₁ → excitation coil EC ₁₂ → inverter INV ₁ Since the current is flowing in the direction, the first solenoid 12 shown in Figure 1 a and c is energized and the plunger 13 is attracted. As a result, the engagement plate 14 is pulled up and the locking state of the presser plate 5 with the engagement recess 5a is released, and the sickle 4 becomes rotatable. Here, the delivery person turns the lock key _KL to turn the sickle 4 from the position shown by the broken line to the position shown by the two-dot chain line, and locks the sickle 4. At this time, the spring 21 moves from the position indicated by the solid line to the position indicated by the two-dot chain line, as shown in FIG. 1d, and is maintained in the locked position by the repulsive force of the spring 21.

Note that when the door C is open, even if the first solenoid 12 is in an operable state, the reed switch 11 is turned off, so even if the push button switch 10 is pressed, the first solenoid 12 is not activated.
does not operate and therefore the lock key _KL cannot be rotated.

Also, when door C is closed and locked,
Since the engagement plate 14 is not engaged with the engagement recess 5a, it can be rotated by the rocker key _KL .
Therefore, when the locker key _KL is inserted into the key insertion hole 2 and rotated, the sickle 4 moves from the position indicated by the two-dot chain line to the position indicated by the broken line (solid line), and is in the unlocked state. Then, when the unlocking is finished, the engagement plate 14 is released by the spring 2.
It is locked in the engagement groove 5a by the pressing force of 2, and rotation by the rocker key _KL is prevented.

Furthermore, when locking/unlocking is performed using the lock key _KL , the locking code may be entered into the keyboard 33 operated only by the administrator, as shown in FIG. For this reason, inverter INV ₂
The level on the output side of is “1” and the excitation coil
Not energized by EC ₁₅ .

Next, when replacing the cylinder _lock 1, as shown in FIG. is input to the CPU 32, and if the electronic key K _E matches,
A lock replacement signal is sent from the CPU 32, and the inverter INV ₂ becomes "0" level and the excitation coil is turned on.
Enable the excitation of the EC ₁₅ .

Next, the manager closes the door C, turns on the reed switch 11 as shown in FIG. 1c, and presses the push button switch 10. As shown in FIG. E→Push button switch
S ₁₀ → Reed switch S ₁₁ → Excitation coil C ₁₅ → Inverter INV ₂ Since the current flows in the direction, the second solenoid 15 in Figure 1c is energized and the plunger 16
is sucked and presses the compression spring 17 to release the cylinder lock 1.
The engagement with the engagement recess 1a is released. Therefore, the cylinder lock 1 becomes free and can be taken out from the lock device.

When inserting the cylinder lock 1 into the lock device, turn on the push button switch 10 and insert the plunger 1 into the lock device.
When the plunger 6 is lowered and inserted, and the push button switch 10 is turned off, the plunger 16 is engaged with the engagement recess 1a by the restoring force of the compression spring 17.

The cylinder lock 1 can be removed by closing the door C and turning on the reed switch 11.
You can lock or unlock the lock key _KL .

Next, when taking out the entire lock device from the case B, first take out the cylinder lock 1 by the above operation, and then rotate the engaging piece 23 clockwise in Fig. 1b to remove the lock from the case B. It can be pulled out by disengaging it. Further, to insert the locking device, it is sufficient to simply insert the locking device in the opposite manner to that described above, and the engaging piece 23 is automatically locked.

〔Effect of the invention〕

As explained above, the present invention is equipped with a shared locker for storing delivered goods and locking and unlocking with a locker key, and a key reading device for inserting registered electronic keys owned by the delivery person and the manager into the locker. a locking device is provided in the housing of the locker to enable locking with the locker key only while the electronic key is inserted into the key reading device, and a key insertion hole for inserting the locker key into a cylinder lock of the locking device; An engaging protrusion is provided on the opposite side that rotates when the lock car key is operated, and a sickle for locking with the lock car door is removably fitted into this engaging protrusion, while the door is in an openable state. a first solenoid having means for locking the sickle when the sickle is not engaged with the door to prevent rotation of the sickle and releasing the lock only when the sickle is energized by energization; Further, a second lock having means for locking into an engagement hole formed on the outer circumferential side of the cylinder lock to prevent removal from the lock device and releasing the lock from the cylinder lock only when energized by electricity is applied. a solenoid is provided in parallel to the first solenoid;
Furthermore, in order to energize each solenoid by energizing, a push button switch and a reed switch that turns on when the door is closed are connected in series to each solenoid. Since the lock cannot be locked with a lock key unless it is inserted into the reading device, it prevents danger and unauthorized use caused by a third party storing dangerous goods or items other than the delivered items and locking the door.
Locker safety is maintained. Further, since only the administrator can replace the cylinder lock, if the cylinder lock is replaced at any time after an arbitrary period of time, even if a duplicate lock key is made, it will become unusable immediately, so it is possible to prevent the duplicate key from being made. In addition, even if the lock car key is lost, if the cylinder lock is replaced immediately, the lock car door can be opened, and it can be prevented from being unlocked with a lock car key found by a third party.
It has the advantage of providing safety and reliability against rock cars.
