Abstract

PURPOSE:To eliminate the sticking of excessive ink, paper powder, etc., and to prolong the life of a destaticization means as a result by automatically putting the destaticization means away from a conveyance path for paper, etc., and placing it in a nonoperation state when destaticization is not necessary. CONSTITUTION:On the previously stored retraction day of a destaticization brush 2, namely, the day when electrostatic charging is not recognized until sheets of paper stick on each other, a motor 5 is automatically driven to put the destaticization brush 2 away from the paper conveyance path 1 to a stand-by position, thereby placing the brush in a noncontact state. The temperature and humidity are measured by a thermometer hydrometer at each time and each time electrostatic charging is recognized, the destaticization brush 2 can be driven and controlled to a destaticization position or the stand-by position at each time. Consequently, when the destaticization is not necessary, the destaticization brush 2 is automatically put away from the paper conveyance path 1 to enter the nonoperation state, so neither ink nor paper powder sticks unlike before and then the life of the destaticization brush 2 is therefore prolonged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is, for example, an ATM or C
The present invention relates to a sheet processing apparatus such as D, and more particularly, to a sheet processing apparatus capable of preventing the occurrence of an error even when performing high-speed processing.

[0002]

2. Description of the Related Art In a paper sheet processing apparatus such as that described above, paper sheets are fed to each other in order to prevent an error, that is, the conveyed paper sheets from being superposed by static electricity and causing double-sheet feeding or continuous feeding. It has a structure that removes static electricity to the extent that it sticks.

With this structure, a static elimination brush made of a conductive material is arranged on a paper sheet conveying path for conveying paper sheets, and it is intended to remove static electricity from charged paper sheets. To do.

[0004]

However, in the above-described paper sheet processing apparatus, since the static elimination brush is always in contact with the paper sheet conveying path, ink and paper dust of the paper sheet adheres to the static elimination brush. Then, there is a drawback that the static elimination effect of the static elimination brush is lost at an early stage.

Therefore, according to the present invention, when static elimination is not required, for example, during the rainy season or summer, the static elimination brush is kept away from the paper sheet conveying path to prevent the excess static charge from adhering to the static elimination brush. An object of the present invention is to provide a paper sheet processing apparatus that can extend the period.

[0006]

Means for solving the above problems will be described. The structure of the paper sheet processing is to remove the static electricity of the paper sheets by contacting the charge removing means with the paper sheet conveying path. The device is provided with a recognition means for recognizing the electrification of the paper sheets, and when the electrification is not recognized by the recognition means and the electricity elimination is unnecessary, the electricity elimination means is moved away from the paper sheet conveying path to be non-contact. The paper sheet processing apparatus is provided with a contacting / separating unit for setting the state.

[0007]

In other words, according to the above configuration, the paper sheets are stuck to each other by the calendar in which the rainy season and the like are stored in advance and the recognition means such as the humidity detection means for automatically measuring the humidity and the like. If such a large amount of electrification is not recognized, the contacting / separating unit is driven to separate the charge eliminating unit from the paper sheet conveying path to bring it into a non-contact state.

[0008]

As a result of the above, according to the present invention, when the static elimination is not necessary, the static elimination means automatically separates from the paper sheet conveying path and becomes inactive, so that it is unnecessary as in the conventional case. It is possible to prolong the service life of the static eliminator by the amount that such a large amount of ink or paper powder does not adhere.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a configuration diagram showing a main part of the paper sheet processing apparatus. As shown in FIG. 1, the paper sheet processing apparatus is configured by suspending a static elimination brush 2 on a paper sheet conveying path 1. . The static elimination brush 2 has its tip contacted with the paper sheet transport path 1 to remove static electricity from the charged paper sheets, and from the paper sheet transport path 1 as indicated by an imaginary line. The contacting / separating means 3 is movable so as to move between the retracted position which is separated from the retracted position.
Supported by.

The contacting / separating means 3 pivotally supports the actuator 4 pivotally attached to the upper end of the static elimination brush 2 on the opposite side of the pivotal support portion 2a, and the other end of the actuator 4, and is connected to the output shaft of the motor 5. It is composed of an output rod 6, a motor 5, a static elimination position detection switch 7, and a retracted position detection switch 8. When the static elimination brush 2 is in a suspended state and its tip is in contact with the paper sheet conveying path 1, the actuator 4 becomes horizontal and the tip of the output rod 6 contacts the actuator 7a of the static elimination position detection switch 7. The charge removal position detection switch 7 is turned on. On the contrary, when the static elimination brush 2 is in the retracted position, the tip of the output rod 6 contacts the operator 8a of the retracted position detection switch 8 to cause the retracted position detection switch 8 to move.
Turns on.

The above-mentioned respective parts are controlled by the CPU 10 as shown in the block diagram of FIG. This C
A calendar 9 is connected to the PU 10, and the calendar 9 counts the date. The CPU 10 appropriately reads and writes the data stored in the RAM 12 according to the program stored in the ROM 11 to drive the data.

The data to be stored in the RAM 12 is, for example, a statistically calculated high day or time of high humidity. It should be noted that this data may be adjusted as appropriate in consideration of the environmental conditions of the installation location of the device, and the data may be considered up to the unit of time.

A temperature / humidity meter 13 may be connected as shown by a phantom line in FIG. In this case, only the temperature,
Alternatively, only the humidity is set, and further, both constant values are set, and whether or not the humidity is less than or equal to the constant value is detected.
Further, by allowing the temperature / humidity meter 13 to coexist with the calendar 9, it is possible to perform only necessary static elimination with high accuracy.
The calendar 9 may be omitted and the temperature / humidity meter 13 alone may be used.

The operation of the static elimination brush 2 of the paper sheet processing apparatus thus constructed will be described below with reference to the flowchart of FIG. First, the CPU 10 executes the first step n1.
The date from the calendar 9 is input, the date is determined, and compared with the data stored in the RAM 12 to determine whether it is the day when the static elimination brush 2 is retracted.

If it is determined that it is not the day when the charge removal brush 2 is retracted, the CPU 10 turns off the charge removal position detection switch 7.
It is determined whether or not it is N (second step n2). If the static elimination brush 2 is in the static elimination position and the static elimination position detection switch 7 is not turned on, in the third step n3, the motor 5 is driven until the static elimination position detection switch 7 is turned on.
Set to the static elimination position and finish.

If the static elimination position detection switch 7 is already turned on in the above-mentioned second step n2, the static elimination brush 2 is in the static elimination position, and the process is terminated at that point.

On the other hand, if it is determined in the above-mentioned first step n1 that it is the day of the charge removal brush 2 retreat, the CPU 10 determines in the fourth step n4 whether or not the retreat position detection switch 8 is ON, and the retreat position is determined. If the detection switch 8 is ON,
Since the static elimination brush 2 is in the retracted position, it ends at that point.

If it is determined in the fourth step n4 that the retracted position detection switch 8 is not ON, the CPU 10
Drives the motor 5 until the retracted position detection switch 8 is turned on in the fifth step n5, sets the charge removal brush 2 to the retracted position, and ends the process.

As described above, on the day when the pre-stored static eliminator 2 is retracted, that is, on the day when the electric charge is not recognized enough to cause the sheets to stick to each other, the motor 5 is automatically driven and the static eliminator brush is driven. 2 is separated from the paper sheet transporting path 1 to a retracted position, and is in a non-contact state. It is also possible to measure the temperature and humidity by the temperature / humidity meter 13 each time, and drive the static elimination brush 2 to the static elimination position or the retracted position each time when electrostatic charge is recognized.

Therefore, when static elimination is not necessary,
Since the static elimination brush 2 is automatically separated from the paper sheet conveying path and brought into a non-acting state, extra ink, paper dust, etc. do not adhere to the static elimination brush 2 as in the conventional case, and the static elimination brush 2 is correspondingly removed. It is possible to extend the life of the.

In the correspondence between the structure of the present invention and the above-described embodiment, the charge removing means of the present invention is the charge removing brush 2 of the embodiment.
Similarly, the recognition means corresponds to the calendar 9, the temperature / humidity meter 13, the CPU 10 and the RAM 12, and the contact / separation means corresponds to the actuator 4, the motor 5, the output rod 6, the static elimination position detection switch 7, and the withdrawal. Although corresponding to the position detection switch 8, the present invention is not limited to the configuration of the above-described embodiment.

For example, as shown in FIG. 4, the static elimination brush 22 provided on the paper sheet conveying path 21 may be supported by the biasing spring 23 and the cellophane 24. That is, one end of the biasing spring 23 is fixed to the intermediate portion of the static elimination brush 22 that axially supports the end portion, the static elimination brush 22 is pulled to one side, and one end of the cellophane 24 is fixed to the lower portion of the static elimination brush 22 while the other end is fixed. It is pulled to the side so that the tip of the static elimination brush 22 is in the static elimination position where it comes into contact with the paper sheet transport path 21 when static elimination is required such as low humidity.

With such a structure, the cellophane 24 naturally expands due to its nature when the humidity rises and the elimination of static electricity becomes unnecessary, so that the cellophane 24 is expanded by the urging force of the urging spring 23. The charge-eliminating brush 22 tilts toward the biasing spring 23 and moves to a retracted position away from the paper sheet transport path 21.

In this case, the recognizing means of the present invention corresponds to the cellophane 24 of the embodiment, and similarly, the contacting / separating means corresponds to the biasing spring 23 and the cellophane 24.
