Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stamping device that is used, for example, in an automatic banknote processing device, and prints predetermined items on a sealing band in which a certain number of banknotes are sealed.

2. Description of the Related Art Recently, automatic banknote processing devices such as automatic banknote sorting machines and banknote sorting and sealing machines have been developed and put into practical use in order to efficiently and automatically process increasing amounts of banknotes by mechanical means.

These devices are designed to sort and seal banknotes classified into various types (for example, regular notes, damaged notes, front notes, back notes, A yen notes, and B yen notes) into a fixed number of bills.

In this sealing process, predetermined information (for example, operator's name, handling branch name, machine number, etc.) is placed on the sealing band.
needs to be printed.

However, because of the processing capacity of this type of device, the ink in the stamp tends to run out quickly, and it takes time and effort to replenish the ink frequently. There is an inconvenience that they are different.

Furthermore, even if a predetermined number of banknotes are sealed, there are differences in the sealing thickness for each type of banknote.

As a result, the paper is often transported while being tilted, making it impossible to apply a uniform printing pressure when stamping, and resulting in uneven printing, which often results in missing prints.

The present invention was developed based on the above circumstances, and its purpose is to provide a device for stamping banknotes that does not require replenishment of ink and that provides constant print clarity. .

An embodiment of the present invention will be described below based on the drawings.

In the figure, reference numeral 20 denotes a conveyance path, which includes a roller 21 connected to a drive motor (not shown), a driven roller 22 provided facing away from each other, and these drive rollers 21 . Followed roller 2
2 and a conveyor belt 23 that runs endlessly.

A group of banknotes 24 sealed in a sealing band 24a is supplied to the conveyor belt 23 and is conveyed in the direction of arrow A.

At the end of the conveyance path 20 in the conveyance direction, a fixed base 25 is disposed which is wider than the conveyor belt 23 and has a concave portion (not shown) facing the belt 23 so as not to interfere with each other even if the conveyor belt 23 hangs. has been done.

At the upper part of this fixed base 25 is a stamping operation section 26 which will be described later.
is provided.

That is, it is composed of a stamping means 27, a position regulating means 28, and an actuating means 29 for supporting and operating these means.

First, referring to FIGS. 2 and 3, the actuating means 29 will be explained. A drive motor 32 is connected to a board 30 to which a reduction gear part 32a is connected via mounting brackets 31a and 31b.
b is supported, and a timing cam 33 is fitted onto its drive shaft 32C.

The cam 33 has a microswitch 3 attached to the mounting bracket 31a via a bracket 34.
The actuator 35a of No. 5 is in rolling contact.

When the actuator 35a is located in the recess 33a, the drive motor 32b is de-energized, and when the actuator 35a is located outside the four parts 33a, it is energized.

Further, the timing chart of the timing cam 33 is shown by a broken line in FIG.

The position regulating means 28 will be explained based on FIGS. 2 and 3. It consists of a stop body 28A and a presser body 28B.

That is, a stopper cam 36 is fitted onto the drive shaft 32C adjacent to the timing cam 33, and has a small diameter portion 36a and a large diameter portion 36b as shown in FIG. There is.

Further, a fulcrum bracket 38 is provided on the mounting fitting 31a via a bracket 37, and a stopper 40 is rotatably supported on this by a pin 39.

A stopper piece 40a is provided at one end of the stopper 40, and a leaf spring 4 attached to the fulcrum bracket 38 is attached to the stopper piece 40a.
The free end of 1 is elastically biased to rotate counterclockwise.

Further, the stopper cam 3 is attached to the other end of the stopper 40.
6 is provided, and a microswitch (not shown) is disposed adjacent to the stopper 40.

This microswitch is for sensing the shock when the group of banknotes 24 collides with the stopper 40 and sending a start signal to the drive motor 32b.

The illustrated state represents the start of the drive motor 32b, and the stopper piece 40a closes the transport path 20 to block the group of banknotes 24 being transported, and prevents the rotation of the stopper cam 36. The stopper 40 is adapted to rotate against the elastic force of the leaf spring 41.

In addition, the stopper 4 due to one rotation of the stopper cam 36
The rotation state of 0 is shown by the three-dot chain line in FIG.

A presser body 28B is provided adjacent to the stop body 28A formed in this manner.

That is, a compound cam 42 is fitted onto the drive shaft 32C adjacent to the stopper cam 36, and as shown in FIG. b is formed.

A presser cam floor 43 is in rolling contact with the presser cam 42a, and a stamp cam floor 44 constituting a part of stamp means 27, which will be described later, is in rolling contact with the stamp cam 42b.

The presser cam floor 43 is pivotally supported by a support fitting 46 provided on the presser plate 45.
Also, the tension spring 4 has one end attached to the fixture 31a.
7.47 so as to be elastically pulled upward.

Therefore, as the composite cam 42 rotates, the presser plate 45 moves up and down, and when it is lowered the most, it can press the banknote group 24 on the conveyance path 20.

The illustrated state is when the drive motor 32b is started, and the presser plate 45 is at the highest position, and as the presser cam 42H makes one rotation, the conveyance path 20 is moved as shown by the two-dot chain line in FIG. It is designed to fall and rise relative to the

The presser foot formed in this way is provided with a stamping means 27 adjacent to the body 28B.

That is, as shown in FIGS. 2, 3, and 7, the stamp cam floor 44 is pivotally supported on a truck 48.

This truck 48 is provided with a pair of truck rollers 49 on both sides, and is vertically movable along a guide rail 50 provided on the mounting bracket 31a.

Moreover, a bracket 51 is attached to the truck 48, and is elastically attached so as to be pulled down by a tension spring 52 as a biasing means stretched between the upper end of the bracket 51 and the mounting bracket 31a.

Therefore, the stamp cam floor 44 is always in rolling contact with the stamp cam 42b as a stopping means, and the cam 42
The cart 48 is configured to move up and down as the wheel b rotates.

Note that the tension of the tension spring 52 can be easily adjusted using an adjusting screw portion 52a.

Further, the carriage 48 is provided with guide pieces 53, 53 for guiding the support fitting 46, and the stamp body 54 is detachably fixed via a stopper 55.

The stamp body 54 is made of a porous rubber stamp that does not require replenishment of stamp ink at all, and a stamp surface 54a on which predetermined information is engraved is formed on the lower end surface.

The illustrated state of the cart 48 and the stamp main body 54 is when the drive motor 32b is started, and is at the highest raised position, and as the stamp cam 42b makes one rotation, the 9th
As shown by the dashed line in the figure, it descends and rises.

Note that when the stamp body 54 descends the most, the stamp surface 54
Since a extends beyond the presser plate 45 and protrudes downward, the presser plate 45 has an escape hole 56 as shown in FIG.
is drilled.

Next, the operation of the above embodiment will be explained.

The group of banknotes 24 sealed by the sealing band 24a is conveyed in the direction of arrow A by the conveyor belt 23, and the banknote group 24 is conveyed by the conveyor belt 23 in the direction of arrow A.
collide with

A microswitch (not shown) senses this and sends a start signal to the drive motor 32b.

The timing cam 33 and the stopper cam 36
, the presser cam 42a and the stamp cam 42b start rotating at the same time.

However, while the stopper cam 36 rotates approximately 90 degrees, the stopper 40 maintains its state as shown in FIG.
There will be sliding contact with.

Before the stopper 40 starts rotating, the presser plate 45 first descends to press the banknote group 24 against the fixing base 25.

Therefore, the banknote group 24 having a bulge is compressed to a certain degree, and the sealing band 24a is reliably glued.

Note that since the fixed base 25 has a concave portion for escape of the conveyor belt 23, the belt 23 continues to run without any trouble.

The stamp body 54 descends next to the presser plate 45, and the stamp surface 54a protrudes from the escape hole 56 and comes into contact with the sealing band 24a of the paper stack group 24.

In other words, predetermined items are printed on the sealing band 24a.

Note that since the stamping pressure at this time can be adjusted using the adjusting screw portion 52a, printing can be performed at a constant density without excessive ink coming out.

During printing, the stopper 40 gradually rotates to open the top of the conveyance path 20, but the presser plate 45 continues to press the banknote group 24 even after printing is completed and the stamp body 54 gradually rises.

The stopper 40 substantially opens the top of the conveyance path 20, and the presser plate 45 starts rising just before the stamp body 54 rises the most.

Therefore, the group of banknotes 24 is protected by the presser plate 45 and gradually swells back to its original state without coming into contact with the stamping surface 54a and getting dirty, and when the presser plate 45 is separated, it is returned to the conveyance path 2.
Transported by 0.

Note that when the drive shaft 32C rotates once, the presser plate 45
The stamp body 54 is at the highest position, the stopper 45 rotates to close the conveyance path 20 again just before that, and the actuator 35 a of the microswitch 35 is located in the recess 33 a of the timing cam 33 . The drive motor 32b then stops.

In the above embodiment, the conveyance path 20 is connected to the conveyor belt 2.
3 and rollers 21, 22, etc., but the present invention is not limited thereto; for example, a slide or the like may be used, as long as it can transport and guide the group of banknotes 24.

Furthermore, although the stamp actuating section 26 is provided above the conveyance path 20, it is not limited thereto, and may be placed on the left, right, or below the conveyance path 20.

Further, the actuating means 29 is equipped with a drive motor 32b, and this drive rotates various cams 33, 36, 40 to perform predetermined operations, but the invention is not limited to this. Alternatively, a predetermined operation may be performed using pneumatic pressure or the like.

In addition, the stamping means 27, the stop body 28A, and the presser are attached to the body 28.
Although B and B are integrally formed, they may be provided and operated completely separately.

Furthermore, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

As explained above, according to the present invention, since the stamping means for stamping a group of banknotes in which a predetermined number of banknotes conveyed to the conveyance path are sealed by the paper bank is equipped with a porous rubber stamp that does not require ink replenishment, It eliminates the need for extra mechanisms such as an ink bed and ink bed transport mechanism, reducing costs, reducing time and effort, and providing consistent print density.
Furthermore, the different thicknesses of different banknotes can be absorbed by the biasing means when stamping, making it easy to adjust the stamping force. Even if the banknotes are conveyed at an angle, the porous rubber stamp does not cause uneven printing. This has the effect of preventing the printing from falling off and ensuring clear printing at all times.
