It was designed to reduce the shock during operation.

[0003]

However, the above-mentioned prior art has the following problems.

[0004] In other words, rubber that acts as a cushioning material when the gate is stopped has characteristics such that the damping characteristics greatly depend on temperature, creep deformation under a long-term load, and are liable to deteriorate due to aging. Optimization work at the time of design to cope with the environment becomes enormous, periodic replacement is required, and development / maintenance costs are high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a schematic view of a gate mechanism of a bill handling apparatus according to one embodiment of the present invention. FIG. 2 is a front / top view showing details of a method of fixing a direct acting solenoid that is a gate driving source.

A gate 1, which is a guide member, is connected to and supported by a shaft 2 of a support member. The shaft 2
The shafts 2 are fixed to the frames 4a, 4b via bearings 3a, 3b, and a link 5 as a connecting member is attached to one end of the shaft 2. The link 5 is connected via a lever 6 to a movable iron core of a direct acting solenoid 7 which is a driving source, and a gate return spring 8 when the direct acting solenoid 7 is demagnetized is attached. The gate 1 is oscillated by the excitation / demagnetization of 7.

A member that limits the operation stroke of the direct acting solenoid is a stopper 9. The stopper 9 also serves as a bracket for fixing the direct acting solenoid 7 to the frame 4a. In addition, the direct acting solenoid 7
Is rigidly fixed to the stopper 9.

The stopper 9 is provided with a weak rigid portion 10 having a low rigidity in the operation direction of the direct acting solenoid 7.
A structure that is provided near the stroke end of the direct acting solenoid and is easy to swing around the weak stiffness portion 10, so that the shock during the operation of the direct acting solenoid 7 can be effectively released. It has become. The stopper 9 is rigidly fixed to the frame 4.

Next, the operation of the switching gate having the above configuration will be described with reference to FIG.

The gate 1 is normally operated (when the direct-acting solenoid 7
4 is in a non-excited state).
Is transported along the upper surface of the gate 1 and guided to the transport path A.

When the gate is switched (direct-acting solenoid 7
Is excited), the attraction force of the solenoid causes
The gate 1 is held at the position B, and the bills 14 transported by the transport belt 13 move along the lower surface of the gate 1 and are guided to the transport path B.

When the bill 14 reaches the position before the gate 1, the direct acting solenoid 7 is excited / demagnetized in accordance with the destination of the bill 14, and the destination of the bill 14 is switched.

If the gate switching time is too slow,
The gate and the tip of the bill interfere with each other, causing transport trouble.
On the other hand, when the banknotes are continuously conveyed at substantially constant intervals as in the banknote handling apparatus according to the present embodiment, the gate switching timing is adjusted to avoid interference between the gate and the banknote tip. If it is made earlier, the rear end of the preceding bill will interfere with the gate, which will again cause a transport trouble.

Further, in the bill handling apparatus, it is necessary to process bills at a high speed, and when the gate is switched, the gate satisfies the condition that it does not interfere with the rear end of the preceding bill and does not interfere with the leading end of the bill to be switched. In order to ensure the reliability of the device, the switching operation of the gate must be completed in a short time.

Next, the state of the actual gate operation according to the prior art using no cushioning material, the prior art using the cushioning material, and the present embodiment will be described with reference to FIGS.

As shown in FIG. 4, in a conventional general gate mechanism in which the stopper and the gate are not fixed and have no cushioning material, the operation state of the gate is at the stroke end of the solenoid 7 as shown in FIG. When the movable iron core and the stopper 4 collide, the movable iron core and the gate 1 rebound greatly, exceeding the mechanically allowable rebound amount, which may increase the practical gate operation time.

In order to improve the rebound characteristics, a stopper 9 for fixing a direct acting solenoid is fixed to a bracket 11 so as to be slidable in the operating direction of the solenoid, as shown in FIG. In the prior art in which the movement is regulated by the rubber damper 12, as shown in FIG. 7, good gate operation characteristics in which rebound is suppressed are exhibited.

However, as shown in FIG. 8, the rebound resilience of rubber greatly depends on the temperature.
As shown in the figure, the material selection to secure the performance over a wide temperature range due to the large rebound of the movable iron core / gate,
The work of shape optimization was enormous. Furthermore, rubber materials have creep properties,
Periodic replacement of rubber was required, resulting in increased maintenance costs.

Therefore, in order to facilitate the optimization work and reduce the maintenance cost, in the present embodiment, the stopper 4 is integrated with the solenoid 7 and swings around the weak rigid portion, so that the impact during the operation of the solenoid 7 is reduced. Is effectively released, and the weak rigid portion is provided in the vicinity of the stroke end of the movable iron core (a portion where the movable iron core and the stopper collide), so that the swinging motion of the stopper affects the movement of the gate 1. The configuration has almost no effect.

That is, as shown in FIG. 11, the impact when the plunger of the solenoid collides with the stopper is as follows.
The stopper holding the solenoid body and having a large inertial mass is effectively alleviated by slowly swinging. The large inertial mass of the stopper also has the effect of reducing the movement of the stopper itself. In addition, the swing direction of the stopper is substantially perpendicular to the operation direction of the plunger, and the weak rigid portion serving as the swing center is also located near the stroke end. It does not affect.

In addition, since there is no need to use a material having a large environmental dependency such as rubber for cushioning the impact, it can be used under a wide range of temperature conditions.
In addition, good gate operation characteristics as shown in FIG. 10 can be maintained over a long period of time.

As described above, since there is almost no influence of the surrounding environment, optimization is easy, and since there is almost no aging, the maintenance cost is small and the settling time is short, that is, the operating time in practical use. , A gate mechanism having high reliability can be obtained.

[0026]

According to the present invention, it is possible to obtain a gate mechanism which is hardly affected by an environmental change, has little characteristic change over a long period of time, and has a short settling time.
Optimization work at design time is easy, no maintenance cost is required,
A gate mechanism with a short operating time in practical use can be obtained,
In the bill transport mechanism, low cost, high processing speed,
The reliability of the device can be improved.
