Description

  The present invention is a consignment receiving device installed in an entrance of a detached house or an apartment house, an office, a leisure facility, or the like, and includes an electric lock used for temporarily storing a delivered item or a luggage. The present invention relates to a receiving device.

Conventionally, in a load receiving device that locks and unlocks a door with an electric lock, there is a type that is automatically locked when a predetermined operation is performed and the door is closed, and the door can be locked without performing a locking operation with a key or the like. Because it is locked, you can prevent forgetting to lock. However, humans and animals may be trapped in the warehouse of such a type of receiving apparatus.
Therefore, various measures have been proposed for monitoring the situation in the warehouse of the consignment receiving apparatus using a sensor or the like and preventing such a confinement accident.

For example, in Patent Document 1 below, there is a cargo receiving device that includes a luggage sensor that detects the contents in a warehouse, a determination unit that detects fluctuations in the output of the luggage sensor, and a door sensor that detects an open / closed state of the door. It is disclosed. According to this, when the closed state of the door is detected by the door sensor and a change in the output of the luggage sensor is detected a predetermined number of times, it is determined as abnormal, the door is unlocked, and the door can be opened.
Patent Document 2 listed below discloses a load receiving device that includes a moving body sensor that detects that a moving body is housed in a warehouse, and that unlocks the door when the moving body sensor detects the moving body. According to this, it is supposed that a moving body can be reliably detected without erroneously detecting it as a load.
Japanese Utility Model Publication No. 7-19197 JP 11-313756 A

However, what prevents such a confinement accident using such a sensor has the following problems.
Like the thing of the said patent document 1, when detecting an abnormal condition based on the detection condition of a package sensor, it is a premise that a moving body moves in a warehouse, for example, the child trapped accidentally is warehoused. If it does not move within, it is not detected that a person is trapped. Therefore, when a child is confined in a tight state in a narrow warehouse, it is determined as a contained item (luggage) and the electric lock is not released, and a confinement accident cannot be prevented.
In addition, when an external force such as an earthquake works to move the receiving device itself, the stored item in the warehouse may be mistakenly detected as a moving object, and the electric lock may be unlocked. .
As described in Patent Document 2, if a moving body sensor that detects a change in infrared rays emitted from a moving body is used, even if a person confined in the warehouse is stationary, it is detected that the moving body is moving. However, in this case, there is a problem of erroneous detection due to the influence of a temperature change in the storage.

Therefore, both the baggage sensor that outputs a baggage detection signal when it detects that there is an object in the warehouse of the cargo receiving device and the moving body sensor that outputs a moving object detection signal when it detects that a moving body such as a human body or an animal is in the warehouse. It is conceivable to solve these problems by providing these sensors independently.
However, in this case, it is necessary to provide an algorithm for avoiding erroneous detection for each sensor, and a new problem arises that the program code becomes enlarged if the determination criteria become complicated. In addition, when a plurality of sensors are used in this way, power is consumed excessively.
As described above, if the electric lock is unlocked due to erroneous detection by the sensor and the door can be opened, the delivery may be stolen. There is a need for something that can monitor and determine the contents.

  The present invention has been made in view of the above circumstances, and is capable of preventing an accident that a moving body such as a human body or an animal is accidentally trapped in a warehouse, and can properly prevent malfunction of automatic unlocking due to erroneous detection. I will provide a.

  In order to solve the above-described problem, a cargo receiving device according to the present invention includes a luggage storage provided with a door having an electric lock, and a luggage that outputs a luggage detection signal when it is detected that there is an object in the luggage storage. A sensor, an infrared type moving body sensor that outputs a moving body detection signal when it detects that the object in the luggage storage is a moving body, and a control unit that automatically unlocks the electric lock when it is determined that there is a moving body. The control unit determines that there is a moving object when the luggage sensor outputs the luggage detection signal and the moving object sensor outputs the moving object detection signal, and automatically unlocks the electric lock. And

In the present invention, it further includes a door sensor that detects an open / closed state of the door, and the control unit detects that the door is in an open state by the door sensor, or the load sensor detects the load. When at least one of the detection signals is not output, the energization of the moving body sensor may be stopped.
According to this, when the load receiving device stops energization to the moving body sensor, the time for energizing the moving body sensor can be set to the minimum. In other words, when the door is open or when there are no items in the cabinet, the moving object cannot be confined, and there is no point in detecting the moving object. Can save the standby power.
Therefore, useless standby power consumed by the moving body sensor is suppressed, so that an increase in power consumption due to the addition of the sensor can be reduced.
In addition, moving object detection when the door is open is easily affected by external scattered light entering the cabinet from the outside and outside air temperature, such as detecting the hand of the person opening the door and loading it, etc. Although there is a high possibility of erroneous detection, the interlocking control with the door sensor prevents the moving body sensor from operating when the door is in the open state, so that erroneous detection does not occur.

Further, the control unit may automatically unlock the electric lock when a predetermined time elapses while the luggage sensor outputs the luggage detection signal and the moving body sensor outputs the moving body detection signal. .
According to this, for example, when the door is opened and closed, a temporary temperature change occurs and the moving body sensor detects the moving body, so that the false detection of the moving body sensor can be prevented, and the situation inside the warehouse can be grasped more appropriately. can do.

  According to the cargo receiving device according to the present invention, when the load sensor detects the contents in the warehouse and the moving body sensor detects the moving body, the electric lock is automatically unlocked. It is possible to appropriately detect the situation in the warehouse and determine the contents, and prevent moving objects such as human bodies and animals from being confined in the warehouse. That is, even if the temperature inside the container changes due to the influence of the outside air temperature and the like, and the moving body sensor erroneously detects it, the electric lock may be automatically unlocked if the luggage sensor does not detect the contents. Absent. By determining the combination of the detection state of the luggage sensor and the moving body sensor in this way, the situation in the luggage storage can be grasped more accurately without enlarging the program code, and erroneous detection can be prevented. . Therefore, malfunction of automatic unlocking due to erroneous detection can be prevented, and a highly secure cargo receiving apparatus can be obtained.

FIG. 7 is a flowchart showing the basic operation of the second embodiment of the consignment receiving apparatus according to the present invention, and FIG. 8 is the operation of each part during the detection of the moving object of the consignment receiving apparatus. It is a time chart which shows a condition.

First, a first embodiment of the present invention will be described with reference to FIGS.
The consignment receiving apparatus 1 according to the present invention is used to temporarily store and deliver a delivery delivered to an answering house instead of a resident. The consignment receiving device 1 is installed in a part of an entrance hall of an apartment house such as an apartment, and a plurality of consignment receiving devices 1 are combined as shown in FIG.
Since the delivery box A is used jointly by the residents of the apartment house, enter the room number and password so that the delivered items stored in the receiving device 1 will not be delivered to the non-destination residents. Thus, the door 10 can be opened, and the door 10 is locked and unlocked by the electric lock 2 controlled by an electric signal.
Note that the shape, combination, and number of the consignment receiving devices 1 constituting the delivery box A are not limited to those shown in the drawings.

The delivery box A includes a plurality of receiving devices 1 having different sizes, a stamping device 15 that can automatically stamp a receipt when a delivery agent puts a non-delivery delivery slip, a setting of a personal identification number, various services being stopped, And a setting device 16 for setting (see FIG. 2). The consignment device 1 includes a box-shaped luggage storage 17 having a front opening in which stored items such as deliverables are stored, a door 10 provided to close the front opening and open and close via a hinge portion 10a, a room A numeric keypad for inputting a number and a personal identification number, an operation key such as a delivery button, a receipt button, and the like are provided, and an operation display unit 11 for displaying whether or not it is empty is provided. A handle 12 for opening and closing the door, an emergency unlocking key portion 13, an electric lock 2 for locking and unlocking the key based on an electric signal, and a door sensor 5 for detecting the open / closed state of the door 10. It has been. The door sensor 5 can be configured, for example, by providing a limit switch inside the unit of the electric lock 2 or by providing a photoelectric filler sensor in the door 10 or the like. In the recess 17aa of the ceiling surface 17a of the luggage storage 17, a moving body sensor 4 for outputting a moving body detection signal is embedded when it is detected that there is a moving object such as a human being or an animal in the luggage storage 17. A baggage sensor 3 for outputting a baggage detection signal is embedded in the recess 17ba of the floor surface 17b when it is detected that there is an item in the baggage storage 17. Thus, if the moving body sensor 4 and the luggage sensor 3 are embedded, the detection can be performed satisfactorily without interfering with the contents in the luggage storage 17. As the moving body sensor 4, a sensor that detects that the object in the luggage storage 17 is a moving body such as a human body is used, and an infrared detection type sensor is preferable. Examples of the luggage sensor 3 include an infrared reflection type distance measuring sensor and a load sensor such as a load cell. In the figure, an example is shown in which the moving body sensor 4 and the luggage sensor 3 are provided one by one in the center of the ceiling surface 17a and the floor surface 17b. However, the present invention is not limited to this. Also good.
The electric lock 2, the luggage sensor 3, the moving body sensor 4, and the door sensor 5 are controlled by the control unit 6, and the control unit 6 supplies power from the power source 7 and is connected to each of the above-described sensors through signal lines or the like. Is driving. The control unit 6 includes a timer unit 8 that measures a predetermined time T described later.

Next, with respect to the method of using the luggage apparatus 1, an example of an operation from when the delivery item is delivered by the delivery company to the resident of the apartment house receiving the delivery item will be described.
The delivery agent selects the empty receiving device 1 by checking the operation display unit 11 in consideration of the size of the delivered item among the receiving devices 1 installed in the delivery box A. The door 10 of the cargo receiving device 1 is opened, and the delivered goods are stored in the luggage storage 17. At this time, it is desirable to place a delivery item in the center of the luggage storage 17 so that the detection by the luggage sensor 3 and the moving body sensor 4 is good. When a delivery button (not shown) provided on the operation display unit 11 is pressed and a room number of a delivery destination is input, when the door 10 is closed, the door sensor 5 detects that the door 10 is closed, and the electric lock 2 Is activated and locked. At this time, a room number is displayed on the operation display unit 11. When the absent delivery slip is put into the stamping device 15 of the delivery box A, the receipt stamp is printed on the absent delivery slip, and the delivery of the delivery is completed. Thereafter, if the delivery agent posts the absence delivery slip to the delivery destination resident's mailbox, the resident can recognize that the delivery item has been delivered to the consignment device 1.

The resident who has received the absent delivery slip goes to the delivery box A, looks at the operation display unit 11 for the consignment device 1 on which his / her room number is displayed, presses the receipt button (not shown) of the consignment device 1, and Enter the security code assigned to each number. If the entered password is correct, the electronic lock 2 is unlocked. Then, the door 10 can be opened to receive the delivery.
The above-described operation example is merely an example, and if a number is assigned to the receiving device 1 and a predetermined operation is performed, a notification that automatically displays the number, delivery date, etc. of the receiving device 1 that houses the delivery is automatically displayed. It may be printed. Further, when the door 10 is closed, the door 10 may be closed after a lock set button (not shown) provided in the luggage storage 17 is pushed down. Further, after the delivery item is stored in the luggage storage 17, the room number may not be displayed for crime prevention, but a notification of arrival (such as turning on a lamp) may be displayed.

Next, the detection control in the luggage storage 17 of the cargo receiving device 1 and the method for determining the contents will be described in detail with reference to FIGS. 1 and 4 to 6.
FIG. 1 shows a flowchart (S100 to S106) of basic operations in the first embodiment. In this flowchart, an example of operation after the door sensor 5 detects that the door 10 is closed after a predetermined operation and the electric lock 2 is automatically locked is described. Further, the door sensor 5 and the luggage sensor 3 are always supplied with electric power, and can be detected as long as electric power is supplied.
When the door sensor 5 detects the closed state (S100), and the luggage sensor 3 detects that there is an object in the luggage storage 17, a luggage detection signal is output (S101), and the moving body sensor 4 detects that there is a moving body. When the moving object detection signal is output (S102), it is determined that there is a moving object in the luggage storage 17, and the electric lock 2 is unlocked (S103). This series of operations is also illustrated in the time chart of FIG.
Thus, the situation in the luggage storage 17 can be more appropriately determined by combining the detection states of the luggage sensor 3 and the motion sensor 4 to determine the situation in the luggage storage 17 without enlarging the program code. Can be detected and false detection can be prevented.
On the other hand, if the door sensor 5 detects the open state of the door 10 (S100) and the luggage sensor 3 does not detect the presence of an object, that is, if no luggage detection signal is output (S104), the moving body sensor 4 is energized. Is stopped (OFF) (S105).
According to this, since the time for energizing the moving body sensor 4 can be set to the minimum, useless standby power can be saved.
Here, a case has been described in which energization is stopped when the door sensor 5 detects that the door is in the open state and the luggage sensor 3 does not output a luggage detection signal. When the sensor 5 detects that the vehicle is in the open state, or when the luggage sensor 3 does not output a luggage detection signal, the same effect can be obtained even if the energization to the moving body sensor 4 is stopped. be able to.
Regarding the control that employs the case where the energization of the moving body sensor 4 is stopped when the door sensor 5 detects the open state, when the luggage sensor 3 does not output the luggage detection signal in the time chart of FIG. The control employing the case where the energization of the moving body sensor 4 is stopped is shown in the time chart of FIG.

FIG. 4 shows the operation status of each sensor (door sensor 5, baggage sensor 3, and dynamic sensor 4) and the energization status of the dynamic sensor 4 when it is detected that a moving object is stored in the luggage storage 17 as a stored item. It is a time chart which shows.
As shown here, the baggage sensor 3 detects the presence of the baggage and outputs a baggage detection signal when the baggage is stored in the baggage storage 17. At this time, since the door 10 is in the open state, the energization of the moving body sensor 4 is not yet performed, and the energization is OFF. When it is detected that the door 10 is in the closed state, power is supplied to the moving body sensor 4 (energization ON state), and the determination period in the luggage storage 17 by the luggage sensor 3 and the moving body sensor 4 starts. This determination period continues until the door 10 is opened again. When the energized moving body sensor 4 detects the moving body and outputs a moving body detection signal, it immediately determines that a confinement accident has occurred and automatically unlocks the electric lock 2. According to this, a confinement accident can be prevented quickly and countermeasures can be taken promptly.

  Thereafter, in order to notify a manager or the like of a confinement accident, notification may be performed by turning on a lamp or sounding a siren. Further, a spring mechanism or a motor may be built in the door 10 so that the door 10 automatically opens when the electric lock 2 is unlocked.

FIG. 5 shows the operation status of each sensor (door sensor 5, baggage sensor 3, and moving body sensor 4) and the energization state of the moving body sensor 4 when it is detected that the baggage is stored in the baggage storage 17 as a stored item. It is a time chart which shows.
As shown here, the baggage sensor 3 detects the presence of the baggage and outputs a baggage detection signal when the baggage is stored in the baggage storage 17. At this time, since the door 10 is in the open state, the energization of the moving body sensor 4 is not yet performed, and the energization is OFF. Then, when it is detected that the door 10 is in the closed state, electric power is supplied to the moving body sensor 4 and a determination period in the luggage storage 17 by the luggage sensor 3 and the moving body sensor 4 starts. This determination period continues until the door 10 is opened again. The process so far is the same as the time chart of FIG. In this case, since the contents are luggage, the moving body sensor 4 that is in the energized ON state does not detect the moving body. Therefore, automatic unlocking is not performed, and the determination period continues until the door sensor 5 detects that the door 10 is opened again. When the open state of the door 10 is detected, the energization of the moving body sensor 4 is stopped and the energization is turned off. On the other hand, the detection state of the luggage sensor 3 is continued until the luggage is taken out from the luggage storage case 17.

FIG. 6 is a time chart showing an operation state of each sensor (the door sensor 5, the luggage sensor 3, and the moving body sensor 4) when nothing is accommodated in the luggage storage case 17.
As shown here, the luggage sensor 3 is in a state that does not always detect the presence of an object regardless of whether the door 10 is opened or closed, and no luggage detection signal is output. On the other hand, the moving body sensor 4 shown here is energized only when the luggage sensor 3 outputs a luggage detection signal. Therefore, as long as the luggage sensor 3 does not output a luggage detection signal, the door 10 is closed, and the energization of the moving body sensor 4 remains in the OFF state even when the determination period starts.

Next, a second embodiment of the present invention will be described with reference to FIGS. Portions common to the first embodiment are denoted by common reference numerals and description thereof is omitted.
In the first embodiment, when the luggage sensor 3 outputs a luggage detection signal and the moving body sensor 4 outputs a moving body detection signal, the electric lock 2 is automatically unlocked immediately. However, the second embodiment The second embodiment is different from the first embodiment in that the electric lock 2 is automatically unlocked when a predetermined time elapses while the sensor 4 continues to output the moving object detection signal. Therefore, in the control block diagram in the second embodiment, the timer unit 8 indicated by the dotted line in FIG. 3 is provided.
According to this, even though the item stored in the luggage storage 17 is a luggage, the temperature of the interior of the warehouse due to external influences or the luggage device 1 itself moves and the moving body sensor 4 is mistaken for a moving body. When it is detected, it is possible to prevent the automatic unlocking immediately.

FIG. 7 shows a flowchart (S200 to S209) of basic operations in the second embodiment.
In this flowchart, an example of operation after the door sensor 5 detects that the door 10 is closed after a predetermined operation and the electric lock 2 is automatically locked is described. Further, the door sensor 5 and the luggage sensor 3 are always supplied with electric power, and can be detected as long as electric power is supplied.
When the door sensor 5 detects the closed state (S200), the luggage sensor 3 detects that there is an object in the luggage storage 17 and outputs a luggage detection signal (S201), and the moving body sensor 4 has a moving body. When it detects and outputs a moving body detection signal (S202), the timer part 8 is started and time-measurement of predetermined time (T) is started (S203). While the predetermined time is counted, the output of the moving body detection signal of the moving body sensor 4 is continued, and the moving body is detected (S204), and when the predetermined time has passed (S205), it is stored in the luggage storage case 17. The electric lock 2 is unlocked on the assumption that the moving object is housed (S206).
On the other hand, if the moving object detection signal is not output during the predetermined time (S204), the timer unit 8 is reset (S207) until the door 10 is detected again (S200). The determination by the luggage sensor 3 and the moving body sensor 4 is continued.
If the door sensor 5 detects the open state of the door 10 (S200) and the luggage sensor 3 does not detect the presence of an object, that is, if no luggage detection signal is output (S208), only the energization of the moving body sensor 4 is stopped. (OFF) (S209). This control is the same as in the first embodiment.

FIG. 8 is a time chart showing the operation status of each sensor (door sensor 5, luggage sensor 3, moving object sensor 4) and timer unit 8 when it is detected that a moving object is accommodated in the luggage storage 17 as an accommodation. It is a chart. Here, the predetermined time is T, the first time is T1, and the second time is T2.
As shown here, the baggage sensor 3 detects the presence of the baggage and outputs a baggage detection signal when the baggage is stored in the baggage storage 17. At this time, since the door 10 is in the open state, the energization of the moving body sensor 4 is not yet performed, and the energization is OFF. When it is detected that the door 10 is in the closed state, power is supplied to the moving body sensor 4 (energization ON state), and the determination period in the luggage storage 17 by the luggage sensor 3 and the moving body sensor 4 starts. This determination period is the same as that of the first embodiment in that it continues until the door 10 is opened again. Then, when the energized moving body sensor 4 outputs a moving body detection signal, the timer unit 8 is activated to start measuring a predetermined time (T). Here, if the moving body detection signal is no longer output by the moving body sensor 4 while measuring the predetermined time (T), the time counting by the timer unit 8 is reset (T> T1 is indicated). Then, in the state where the output of the luggage detection signal by the luggage sensor 3 continues, when the moving body detection signal is output again by the moving body sensor 4, the timer unit 8 is started again. Even when the predetermined time (T) has elapsed, if the detection signals from the luggage sensor 3 and the moving body sensor 4 continue to be output, it is determined that a confinement accident has occurred and the electric lock 2 is automatically unlocked.

In addition, although the example in which the consignment receiving apparatus 1 was used for the collective housing delivery box A is described here, it is not limited to this, It can apply also to the consignment apparatus for detached houses. In addition, the present invention can also be applied to the cargo receiving device 1 provided in an office, leisure facility, station, or the like.
Further, here, the load receiving device 1 having the door 10 provided only on one side has been described, but the present invention is not limited to this, and the present invention can be applied to a double-sided door type load receiving device 1 having a delivery side door and a receiving side door. In this case, door sensors 3 are provided on both the delivery door and the receiving door, and the above-described control is performed by detecting the open / closed state of both doors 10.
Further, here, an example is described in which the electric lock 2 is locked when the door 10 is closed after a predetermined operation. However, the present invention can also be applied to an apparatus that is automatically locked when the door 10 is closed. .
