Abstract

PURPOSE:To reduce a speed without giving an impact to paper sheets during conveyance as well as to make the paper sheets so as not to be damaged by installing a control means for decelerating a conveying speed of a shift conveying means when a sensor has detected the delivery of these paper sheets. CONSTITUTION:Paper sheets 2 in conveyance at a constant speed are discharged by a constant speed conveying means 1, and they are received by a speed controllable shift conveying means 3. This reception is detected by a sensor 5, and on the basis of this detection signal, this conveying means 3 is decelerated by a control means (b), and thereby a conveying speed of the paper sheets 2 during conveyance is decelerated as well. With this constitution, the paper sheets 2 is smoothly decelerable without giving any impact force to the paper sheets 2 as well as without disarranging their position in the conveyance.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a conveying device for paper sheets such as banknotes,
In particular, the present invention relates to a paper sheet conveying device that has been improved so as to be able to stop the paper sheets being conveyed without damaging them or disturbing their posture.

[Conventional technology]

The need to stop the paper sheets being transported arises when the paper sheets being transported are to be sorted, processed, or inspected.

There are various types of equipment equipped with devices for transporting paper sheets.1 For example, printing machines and copying machines generally handle new paper sheets (
(for example, printing paper), there is relatively little risk of damage such as bending.

However, if the paper sheets to be handled are used banknotes, such as in an automatic teller machine, for example, the paper sheets already have wrinkles and creases, so automatic handling technology is suitable.

Regarding the temporary stopping of paper sheets (banknotes) during conveyance in a paper sheet processing device that handles banknotes, Japanese Patent Laid-Open No. 62-
171862 is publicly known.

[Problem to be solved by the invention]

In the above-mentioned known technology, in order to temporarily stop the banknotes that have been conveyed by being sandwiched between two sets of conveyor belts that are in contact with each other,
The banknotes were sent out from the conveyor belt, and the banknotes were brought into contact with a stopper, which was a rigid member.

In this way, if the inertia of the ejected banknotes is caused to collide with the rigid member and stopped, the leading edge of the paper sheet may be bent or the conveyance posture of the paper sheet may be disturbed, which may cause the paper sheet to be transferred in the next process. There was a risk that the paper would skew or jam.

The present invention has been made in view of the above circumstances.

Even if the object to be handled is a paper sheet that easily bends or bends, such as used banknotes, there is no risk of damaging it or disturbing its posture, and the paper is equipped with a mid-stop function. The purpose of the present invention is to provide a transportation device for leaves.

[Means to solve the problem]

The basic principle of the paper sheet conveying device according to the present invention, which was created to achieve the above object, is that a variable speed conveying means is provided in the middle of the conveying path to slow down the received paper sheets. The variable speed conveying means smoothly decelerates and stops the paper sheets without giving any impact to them.

Based on the above-mentioned principle, and as a specific configuration for adapting it to practical equipment, the device of the present invention includes means for conveying paper sheets at a constant speed, and an extension of the constant-speed conveyance means in the conveyance direction. a speed-controllable variable-speed conveyance means which is provided in the apparatus and receives the paper sheet by sandwiching it between a pair of rotating members;

a sensor for detecting that the paper sheet is delivered from the constant speed transport means to the variable speed transport means; and a sensor that reduces the transport speed of the variable speed transport means when the sensor detects the delivery of the paper sheet. The system is equipped with a control means for controlling the

[Effect]

According to the above configuration, instead of ejecting paper sheets being conveyed at a constant speed and hitting a stopper, the paper sheets are received by the variable speed conveying means, and the variable speed conveying means is decelerated to stop the paper sheets being conveyed. Decrease the conveyance speed of paper sheets.

Therefore, it is possible to smoothly decelerate the paper sheet without applying an impact force to the sheet and without disturbing its posture during conveyance.

When implementing the present invention, the speed after the deceleration operation is completed can be set arbitrarily.

That is, it may be decelerated and stopped.

Further, even if the sheet hits a stopper after being decelerated, the impact force that the sheet receives is extremely small.

Furthermore, it is also possible to pass through deceleration and return in the opposite direction.

As described above, the paper sheet conveying device of the present invention has a wide range of applications.

〔Example〕

FIG. 1 is an explanatory diagram in which a control system diagram is added to a perspective view schematically depicting one embodiment of a paper sheet conveying device according to the present invention.

A constant speed conveyance means consisting of belts la and lb sandwiches paper sheets (used banknotes in this example) 2 between the belts and conveys them at high speed in the front direction in the figure, and a variable speed conveyance means consisting of rollers 3a and 3b. It is fed into the conveying means 3.

The variable speed conveying means 3 described above is driven by a motor 4.

The motor 4 mentioned above is driven by a motor drive circuit C which is controlled by a motor speed control circuit.

A non-contact type sensor 5 for detecting paper sheets 2 is provided near the variable speed conveying means 3.

In this example, the sensor 5 is a reflective optical sensor that detects the arrival of banknotes having a magnetic strip drive on its surface.

Sensor 5 above is paper leaf 1! When the arrival of i (banknotes) 2 is not detected, the motor speed control circuit controls the conveyance speed of the variable speed conveyance means 3 (i.e., the circumference of the rollers 3a, 3b) via the motor drive circuit C and the motor 4. speed) is controlled to be equal to the transport speed of the constant speed transport means 1.

Therefore, the paper sheets 2 are smoothly transferred from the constant speed conveying means 1 to the variable speed conveying means 3.

At the moment when the above transfer occurs, the sensor 5 provides a detection sensor output a to the motor speed control circuit.

The motor speed control circuit S, which receives the detection sensor output a, reduces the rotational speed of the motor 4 via the motor drive circuit C, so that the paper sheet (banknote) 2 is transferred between the pair of rollers of the variable speed conveying means 3. After passing between 3a and 3b, the speed is made almost zero.

As described above, the paper sheet (banknote) 2 that has been decelerated to a nearly stopped state and sent out from the variable speed conveying means 3 is inserted between the direction changing roller 6 and the holding roller 7.

The direction changing roller 6 is rotated intermittently by a motor 8.
It has a structure that can be rotated by 80 degrees, and has rubber rollers 6a and 6b on the negative side.

Insert leaves (banknotes) 2.

In this state, the rubber rollers 6a and 6b are driven to rotate counterclockwise in the figure, and the paper sheet (banknote) 2 is sent to the left in the figure and inserted between the pair of belts 9a and 9b of the carry-out conveyance means 9.

The carrying out conveyance means 9 includes a pair of belts 9a.

Paper sheets (banknotes) 2 are sandwiched between the paper sheets 9b and sent out to the left in the figure.
