Description

Description: TECHNICAL FIELD The present invention relates to a sheet switching gate for switching the transport direction of a sheet being conveyed by a belt in a sheet handling device, and particularly, at a high speed and selectively in the conveying direction. The present invention relates to a paper sheet switching gate having a shape suitable for a high-speed gate for switching between sheets.

[Conventional technology]

For example, in a recycle type banknote handling apparatus, the banknotes that are collectively inserted by a user are sent to a transport path while being separated one by one, and in the middle of this transport path, information such as the type of banknote is read or passed. After performing the coefficient of the number of bills and the like, it is necessary to switch the transport direction for each information held by the bills or for each predetermined number of bills and stack them in a stacked state.

As a method of inserting the banknotes, a pair of banknotes separated one by one is sandwiched between contacting and traveling belts,
There is a belt transport system that transports to a predetermined position. In order to switch the conveyance direction of bills to be conveyed in accordance with the above-mentioned demands by using this belt conveyance system, conventionally, a constitution as described below has been widely adopted.

That is, in the middle of the transport path, a substantially triangular space in which a transport belt for sandwiching and transporting banknotes is divided is provided, and the banknotes transported through the transport path are distributed into the space. A swingable triangular switching gate is arranged.

The switching gate is rotatably supported on an axis parallel to the axis supporting the pulley of the conveyor belt, and normally swings by a rotary solenoid or the like so as to sort bills in two different directions. It is configured as follows.

The switching gate is rotated normally or reversely in response to a switching command signal from the switching gate, and bills are conveyed using one side of the switching gate as a guide.

As a related device of this type, there is JP-A-58-140890.

[Problems to be solved by the invention]

In the conventional switching gate configured as described above,
No particular consideration was given to the surface state of the part of the switching gate that comes into contact with the paper, and the surface of the switching gate that comes into contact with the paper had a flat shape over the entire surface.
The contact resistance was large when the paper sheet plunged.

As mentioned above, the transfer gate is a part where the conveyor belt is divided and does not require gripping force.Therefore, if the contact resistance is large, it will take time to pass through the switching gate and it will not be possible to convey the sheet at the specified speed. In addition, when the paper conveyance direction becomes unstable, or when the paper enters at high speed, the leading end of the paper buckles and paper jam occurs. Met.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-described problems in a conventional paper sheet switching gate and to stabilize the paper sheet conveyance direction in which the belt is conveyed at high speed. An object of the present invention is to provide a paper sheet switching gate that can be switched.

[Means for solving problems]

The above-mentioned object of the present invention is to realize the paper sheets 29 of the paper sheet switching gates 7 to 7d.
This is achieved by forming grooves 28 on the surfaces 26a to 26d and 27a to 27d that contact with the sheet, which are inclined from the center in the width direction of the paper sheet conveyance path to the outside with respect to the paper sheet conveyance direction by a constant angle.

[Action]

By forming a groove inclined from the center of the paper conveyance direction to the outside on the surface of the paper conveyance direction switching gate that comes into contact with the paper, and lowering the surface friction coefficient, the contact resistance at the time of paper contact decreases. As a result, there is no delay in the passage of paper sheets through the switching gate, and even when a paper sheet rushes in at high speed, the leading edge of the paper sheet will not buckle and paper jam will not occur.

Further, since the leading edge of the paper sheet is conveyed in contact with the groove formed on the surface of the switching gate, an outward force is applied to the bill,
The slack in the width direction of the bill is corrected and eliminated, and the paper sheet conveyance direction does not become unstable, and stable conveyance characteristics can be obtained.

Next, the configuration of the first banknote switching gate 7, which is one of the banknote switching gates, which is the main point of the present invention, will be described with reference to FIGS. 3 and 1.

In both figures, 23a, 23b, and 23c are banknote transport belts, which are rotatably supported by a frame (not shown) and are fixed to a transport pulley shaft 24 supported in a direction orthogonal to the banknote transport direction at a constant tension. They are arranged in parallel.

The first banknote switching gates 7a, 7b, 7c and 7d, which are made of a material having a small specific gravity and a low friction coefficient, for example, a molded product such as a resin, are provided on both sides of the banknote transport belts 23a, 23b, 23c.
Is fixed to a gate shaft 25 rotatably supported in parallel with the transport pulley shaft 24 while maintaining a constant angle. At one end of the gate shaft 25 is a drive source for displacing a certain angle in the forward and reverse directions,
A rotary solenoid (not shown) is attached.

In addition, of the first banknote switching gates 7a, 7b, 7c and 7d,
Surfaces 26a, 26b, 26c, 26d and 27a, 27b, 27c, 2 that contact bills
A groove 28 as shown in FIG. 3 is formed in 7d at a predetermined inclination angle with respect to the arrow A and arrow B directions which are the conveyance directions of the bill 29.

Next, the operation of the banknote switching gate of this embodiment will be described.

First, when the banknote is conveyed in the direction of arrow A in FIG. 1,
Since the magnetic poles are attracted by the permanent magnet inside the rotary solenoid attached to one end of the gate shaft 25, it is not necessary to drive the rotary solenoid by this attraction force, and the bill 29 is transferred to the bill transport belt. twenty three
When sandwiched between a, 23b, and 23c and a banknote transport belt (not shown) that is disposed so as to face it, when transported in the direction of arrow C, the banknote tip end part comes off the banknote transport belt and becomes free. Become.

However, the bill 29 whose free end becomes free tends to move in the direction of arrow C by the pushing of the bill transport belt, but the leading end of the bill 29 has the first bill switching gates 7a, 7b,
Since it collides with the surfaces 26a, 26b, 26c and 26d of 7c and 7d, the transport direction is changed and the wafers travel along the gate surfaces 26a, 26b, 26c and 26d.

When the bill 29 is conveyed in the direction of arrow B in FIG. 1, the rotary solenoid attached to one end of the gate shaft 25 is driven to rotate the gate shaft 25 in the direction of arrow D by a certain angle. , The first banknote switching gate

After that, when the bill 29 is conveyed in the direction of the arrow C, the leading end of the bill 29 comes off from the bill feeding belt and becomes free, but the leading end of the bill 29 becomes the surface of the first bill switching gates 7a, 7b, 7c and 7d. It collides with 27a, 27b, 27c and 27d, the transport direction is changed, and it advances along the gate surfaces 27a, 27b, 27c and 27d.

As described above, when the banknote transfer direction is switched by the banknote switching gate, the front end of the banknote collides with the surface of the banknote switching gate and further advances along the surface of the banknote switching gate. It is essential to reduce the surface contact resistance of the banknote switching gate, and the groove 28 (FIG. 3) of the banknote switching gate according to the present invention has a very important meaning.

That is, due to the groove 28 provided in the banknote switching gates 7a, 7b, 7c and 7d, the contact resistance between the banknote and the banknote switching gate becomes small, and accordingly, the banknote can smoothly advance through the gate portion, There is no occurrence of banknote jam due to delay of conveyance speed or buckling of banknotes, and further, the banknote tip end part is in contact with the groove on the gate surface to advance, so that outward force is applied to the banknote and slack in the banknote width direction is caused. It is corrected and eliminated, the occurrence of lateral deviation of banknotes is eliminated, and stable conveyance is realized.

FIG. 4 is a view seen from the banknote side entering the banknote switching gate, and the groove 28 has a symmetrical inclination inclined from the center of the width direction of the banknote transport path to the banknote traveling direction by a predetermined angle. have. With the groove 28 having such an inclination,
When the bill passes through the switching gate, it is guided in the directions of arrow E and F to correct slack in the bill in the width direction.
Will be resolved.

In the above-described embodiment, the groove is formed on the surface of the banknote switching gate that comes into contact with the banknotes. However, the size and shape of the groove can be freely selected within a range capable of reducing the contact resistance between the banknote and the gate. It is possible to

Further, in the above embodiment, an example in which the present invention is applied to a bill handling device is shown, but the present invention should not be limited to this, and can be widely applied to a paper sheet transporting device. Needless to say.

〔The invention's effect〕

As described above, according to the present invention, the contact resistance between the switching gate and the sheet can be reduced, so that it is possible to prevent the occurrence of banknote jam due to the delay of the transport speed and the buckling of the banknote, and to guide the banknote to both sides. Since the sheet is conveyed, it is possible to prevent the sheet from being deviated in the width direction, slack, and the like, and it is possible to stably switch the conveying direction of the sheet conveyed by the belt at high speed.
