Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a bag insertion device for an after-hours safe that is equipped with a bag lift device that interlocks with a bag insertion opening opening/closing door.

[Conventional technology]

For the convenience of customers, financial institutions such as banks are equipped with after-hours safes so that deposits can be made even after business hours have ended.

After-hours safes are often used during unattended hours, and their slots are located facing the outside, making them difficult to protect against criminal acts such as tricks from outside. We have a mission to ensure that everything is perfect and safe.

The above-mentioned trick act is when an after-hours safe user or someone else intentionally or maliciously inserts something like a fishing hook into the slot and fishes out a bag, etc. stored inside the safe. , refers to actions such as clogging the slot, applying adhesive or the like to the bottom plate of the slot to attach the bag, or breaking and stealing the slot door. In particular, since it is easy for people who are familiar with the internal structure of after-hours safes to commit crimes, there is a strong tendency to create complex mechanisms in order to completely prevent such crimes.

However, if the bag loading device has a complicated structure, the number of parts will increase, and the number of assembly steps will also increase, resulting in higher costs. The applicant has improved the above-mentioned drawbacks and created an after-hours safe that can store a large amount of bags by opening a part of the wall of a financial institution store to form a bag slot, and installing a slot door in the bag slot. a tower provided with a chute opening in a part of the rear wall of the inlet at a position higher than the bag inlet; A night safe equipped with a lift device for raising and lowering the box has already been proposed.

[The problem that the idea attempts to solve]

The above-mentioned night safe equipped with a lift device moves the lift case up and down in conjunction with the opening/closing operation of the bag slot door, but since the bag slot door is not equipped with a locking mechanism, After putting my bag in my mouth,
Even if the door is closed, it can be opened again.
It cannot be said that the security system is perfect.

[Means to solve the problem]

The present invention solves the above-mentioned problems in the conventional technology, and after a bag is put into the slot, the slot door is completely closed and the door cannot be opened until the lift case is lifted to the top dead center position. The purpose is to provide a bag loading device that cannot be used, and as a specific means to achieve this purpose, the above-mentioned conventional structure in which the lift case moves up and down in conjunction with the opening and closing operation of the bag loading opening opening/closing door is provided. The safe is locked to a lift elevating sprocket that rotates in conjunction with the opening/closing operation of the bag slot opening/closing door, and although the lift elevating sprocket can rotate in the direction of closing the door, it cannot rotate in the direction of opening the door. A pawl body having a locking pawl for blocking is swingably provided on the inner wall of the cylindrical lift housing, and the pawl body includes:
A tension spring that urges the locking pawl to disengage from the teeth of the lift elevating sprocket is tensioned through the connecting rod, and is attached to the middle and upper portions of the inner wall of the cylindrical lift housing. , a limit switch is provided, and a solenoid is fixedly installed above the pawl body, and the solenoid is energized when the intermediate limit switch is activated by the upward movement of the lift case, and de-energized when the upper limit switch is activated; A locking mechanism is provided in which a plunger of the solenoid is connected to the connecting rod so that when the solenoid is energized, the locking claw of the claw body is locked to the lift elevating sprocket against the tension of the tension spring. This paper proposes a bag insertion device for an after-hours safe.

[Effect]

With the above means, after a bag is inserted into the bag slot, the locking pawl of the pawl body slides on the teeth of the lift elevating sprocket in the door closing direction, and the door can be closed.
In the door opening direction, the locking pawl and the teeth engage with each other, making it impossible to open the door.

One of the bag receiving ports 10a communicates with the bag input port 2, and the other bag discharge port 10b opens into the storage 6 at a position higher than the bag input port 2. The cylindrical lift housing 10 includes a lift case 11 that is moved up and down by a bag lift device 9, which will be described later, from a bag receiving port 10a to a bag discharge port 10b. This lift case 11 is formed with a bag storage chamber 12 that faces the bag receiving opening 10a at a lower position of the lift housing 10 and similarly faces the bag outlet 10b at an upper position.
The lower surface of the bag storage chamber 12 is inclined toward the inner side of the storage 6, forming an inclined bottom surface 12a forming an angle of about 45 degrees with respect to the horizontal plane. A pin 13 is attached to the lower end of the inside of the lift case 11, and a flap 14 is pivotally supported on the pin 13.

Next, the bag lift device 9 that moves the lift case 11 up and down inside the cylindrical lift housing 10 will be explained. Upper and lower shafts 20 and 21 of the cylindrical lift housing 10
, a pair of left and right lift elevating sprockets 22,
22 and 23, 23 are fixed, and chains 24, 24 are stretched between the upper and lower lift elevating sprockets 22, 22 and 23, 23, respectively. 24' is a counterweight. Then, attach the mounting bracket 1 to the specified position of the left and right chains 24, 24.

At the same time, a driven sprocket 26 having a smaller number of teeth than the driving sprocket 25 is installed at a corresponding position on the lower support shaft 21 of the cylindrical lift housing 10. Then, the driving sprocket 25 and the driven sprocket 2
6, a chain 27 is stretched between the chain 27 and 6. To explain the operating state of the night safe equipped with the above-mentioned bag lift device 9, the user first unlocks the bag slot opening/closing door 3 with the key, and then lifts the handle arm 3a.
Pull it toward you and rotate it around the support shaft 4 to open the door. In the open state, the door 3 is connected to the chute part 3b.
is inclined at an angle of about 45 degrees with respect to the horizontal plane, and the bag input port 2 and the bag receiving port 10a of the cylindrical lift housing 10 communicate with each other.

In addition, with this door opening operation, the drive sprocket 25 attached to the support shaft 4 of the door 3 rotates counterclockwise, causing the drive sprocket 25 and the lower support of the cylindrical lift housing 10 to rotate. A chain 27 stretched between the driven sprocket 26 attached to the shaft 21 causes the driven sprocket 26 to also rotate in the counterclockwise direction. The lift elevating sprockets 23, 23 attached to the shaft concentric with the driven sprocket 26 rotate counterclockwise, and the lift elevating sprockets 23, 23 are attached to the upper shaft 20 of the cylindrical lift housing 10. The chains 24, 24 stretched between the lift raising and lowering sprockets 22, 22 are also rotated in the counterclockwise direction. In this way, the power of the driving sprocket 25 is transmitted to the chains 24, 24 via the chain 27, the driven sprocket 26, and the lower and upper lift elevating sprockets 23, 23 and 22, 22, and is transmitted counterclockwise. direction. And this chain 24,
The lift case 11 suspended from 24 is moved downward from the raised position. Lift case 11 is
In the fully opened state, the bottom dead center position is reached, and at this position, the open end of the bag storage chamber 12 faces the bag receiving opening 10a of the cylindrical lift housing 10,
communicate.

The bag 5 thrown into the opened bag slot 2 slides on the chute part 3b and passes through the cylindrical lift housing 10.
The bag is stored in the bag storage chamber 12 of the lift case 11 having an inclined bottom surface 12a through the bag reception opening 10a. Next, when the door is closed, power is transmitted to the lift case 11 in the opposite manner to the above, and the chains 24, 24 are moved clockwise with the loaded bag 5 inserted and held in the bag storage chamber 12. Rotate to perform a rising motion. In the completely closed state, the lift case 11 reaches the top dead center position, and the open end of the bag storage chamber 12 faces the bag outlet 10b of the cylindrical lift housing 10. Then, the flap 14 falls down from the bag discharge port 10b toward the inside of the storage compartment, opening the open end of the bag storage chamber 12, and the bag 5 is discharged into the storage compartment 6 due to its own weight.

Now, in the after-hours safe equipped with the bag lift device described above, a locking pawl 30a that engages with the teeth of the sprocket 23 is provided above the lower lift elevating sprocket 23 on the inner wall of the cylindrical lift housing 10. A claw body 30 included in the part is pivotably supported by a shaft 31. A pin 32 is implanted in the middle part of the claw body 30, and this pin 32 has a cross section h
One leg 33a of the connecting rod 33 formed in a letter shape
Insert into the elongated hole 33c. Above the claw body 30,
A solenoid 34 is fixedly installed, and a plunger 35 of the solenoid 34 is attached to the other leg 33b of the connecting rod 33.
Connect. A tension spring 36 is tensioned at the upper end of the connecting rod 33.

On the other hand, at the middle part of the inner wall of the cylindrical lift housing 10, that is, at a position approximately at the same height as the upper part of the bag slot opening/closing door 3, there is a one-way operating type that is operated by the lifting movement of the lift case 11. A limit switch 37 is provided, and a similar limit switch 38 is also provided at the top, that is, at the top dead center position of the lift case 11.A timer 39, which is set and reset by both limit switches 37 and 38, Provided within the housing 10.

The operating state of the after-hours safe in which the bag slot opening/closing door 3 is provided with the above locking mechanism will now be described. When the user opens the bag slot door 3 by pulling it toward the user in the direction of arrow A in FIG. Since the end portion is pulled up by the tension spring 36 stretched on the rod 33, the locking pawl 30a of the pawl body does not engage with the teeth of the lift raising/lowering sprocket 23, and the sprocket 23 is free to rotate. condition, therefore, the bag slot door 3
The door can be opened. Insert the bag into the lift case 11 through the opened bag slot 2 and start the door closing operation.
The lift case 11 is moved up in the direction of arrow B in FIG.
The side plate portion 1 contacts the limit switch 37 and operates it, thereby energizing the solenoid 34. At this time, a timer 39 is set.

When the solenoid 34 is energized, the plunger 35
is retracted, the connecting rod 33 is pulled down against the tension of the tension spring 36, and the claw body 3 is connected to the connecting rod 33.
0 is also pulled down, so the locking pawl 30a of the pawl body is brought into engagement with the teeth of the lift raising/lowering sprocket 23. In this state, when you try to close the bag slot door, a force acts on the lift elevating sprocket 23 to rotate it in the clockwise direction as shown in FIG. 32 swings within the elongated hole 33c formed in the connecting rod 33 and slides on the teeth of the lift elevating sprocket 23, allowing the door to be closed without resistance. However, when trying to open the bag slot door 3, the lift elevating sprocket 23 attempts to rotate counterclockwise (in the direction of arrow C) in FIG. The pawl 30a meshes with the teeth of the lift elevating sprocket 23 and becomes unable to rotate.
The door cannot be opened due to the so-called ratchet mechanism.

When the bag slot opening/closing door 3 is completely closed and the lift case 11 reaches the top dead center position of the cylindrical lift housing 10, the bag is discharged into the storage 6 and at the same time the upper limit switch 38 is activated to lift the bag. When the side plate of the case 11 makes contact, the timer 39 is reset, and the power to the solenoid 34 is stopped approximately one second later, the suction force of the solenoid 34 disappears, and the locking pawl 30a of the pawl body and the lift elevating sprocket are removed. The claw body 30 is also pulled up via the connecting rod 33 by the tension of the tension spring 35 which is biased in the direction of disengaging from the engagement with the lift lifting sprocket 23, and the engagement with the lift raising/lowering sprocket 23 is released. . As a result,
The bag slot opening/closing door 3 can be opened and the after-hours safe can be used again.

[Effect of idea]

As described in detail above, according to the bag insertion device for an after-hours safe according to the present invention, the bag insertion opening opening/closing door is provided with a locking mechanism, so that a bag is inserted into the bag insertion opening and the door is once closed. Then, the door cannot be opened from now on, and it cannot be opened again unless the bag slot door is completely closed and the lift case is raised to the top dead center position. Therefore, if a user inserts a bag into the bag slot, closes the bag slot door, and then opens the bag, the bag may remain near the chute or return to the bag slot side. I never go back.
Furthermore, even if a user leaves without fully closing the bag slot door, the next user will not be able to open the door. It is necessary to raise the lift case and drop the bag into the storage compartment. As a result, it is possible to prevent theft due to erroneous operation of the bag slot opening/closing door, and the practical effects of the present invention are great.
