Abstract

PURPOSE:To make it possible to set a force pressing sheets against a sheet take-out means to be in an optimum condition by pressing sheets fed in a supply section against the take-out means and an angularly displacing lever with the use of a pressing member so as to read the rotational displacement of the lever. CONSTITUTION:Sheets P fed in a supply section 11 is pressed by a pressing member 14 in the surface direction, and accordingly, a take-out means 12 abuts against the forehead sheet P. Further, the sheets P are pressed against a lever 25 positioned in the vicinity of the take-out means 12 so that the lever 25 is rotationally displaced. Accordingly, an angle detector 27 reads the rotational displacement of the lever 25. Further, the read data is indicated on a display section 32. With this arrangement in which the read data are always displaced on the display section, the pressing force against sheets P may be set to be in an optimum condition. Further, even though irregular take-out by the take-out means occurs, the time required for tracing and remedying the cause may be shortened.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is directed to a method for taking out paper sheets in which, for example, securities such as checks and slips, or cards, etc. are stacked one by one. This invention relates to a paper sheet retrieval device.

(Prior Art) Conventionally, in a paper sheet processing device that processes securities such as checks and slips, or paper sheets such as cards, one sheet is set in a stacked state, and the stacked paper sheets are A paper sheet take-out device is generally used in which sheets are pressed against a take-out section using a pressure plate and taken out one sheet at a time starting from the earliest sheet. In this type of device, the pressing force between the take-out part and the first sheet taken out by the take-out part is set to a predetermined value, and the pressing force is kept constant even when each sheet is taken out one after another. need to be controlled to maintain it.

Therefore, as a control mechanism conventionally used, when a paper sheet is pressed by a pressing body, a lever is provided facing the front and rotated when the first sheet in the pressing direction is pushed. An angle detector is installed to read the amount of rotational displacement of the lever, and the suppressor is controlled by moving or stopping the suppressor by a predetermined amount based on the detection result of the angle detector.

In such a device, a special device must be used to set the initial position of the pressing body, and furthermore, adjusting the initial position is time consuming.

(Problem to be Solved by the Invention) In a paper sheet take-out device, if the paper sheets are not taken out with the pressing force of the paper sheet that presses the take-out part and the paper sheet in an optimal state, This will result in an ejection error. Therefore, conventionally, as a means to set the optimum value, a special display device (for example, a synchroscope) was used to display the optimum pressing force value, but the l! There was a drawback that it took a considerable amount of time for J adjustment. Furthermore, since it is not always possible to check the current state of the pressing force, there is a problem in that when a failure occurs in ejection, a lot of time is consumed in investigating the cause.

The present invention has been made to solve the above problems,
To provide a paper sheet take-out device which requires less adjustment time to set so that paper sheets can always be taken out with the optimum pressing force, and which can quickly recover even if the device has a failure in taking out sheets. With the goal.

[Structure of the invention]

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a supply unit that supplies paper sheets in a horizontal or upright position, and a supply unit that supplies paper sheets in a horizontal or upright position, and the paper sheets that are supplied to this supply unit. a pressing body that presses the sheet in the plane direction; a take-out means that is provided in contact with the frontmost sheet pressed by the pressing body and takes out the sheets one by one; a driving means for moving the supply section toward the take-out means, and a lever disposed near the take-out means that rotates when the frontmost paper sheet is pressed, and the rotational displacement of the lever It is constructed by providing an angle detector for reading the amount and a display section for displaying the information read by the angle detector.

(for production) That is, the present invention has the above configuration.

Since the reading information detected by the angle detector is always displayed on the display, it is possible to set the pressing force of the sheet against the ejecting means to the optimum state, reducing the time required to adjust the pressing force. Can be done.

Furthermore, since the current state of the pressing force can be known at all times, even if the ejecting means fails to eject paper sheets, the time required to investigate the cause and recover can be shortened.

(Example) The present invention will be described below with reference to an example shown in the drawings. This takeout device can be roughly divided into stacked paper sheets (P),
..., and a take-out part (12) that sequentially takes out the paper sheets (P) in this supply part (P) one by one and transports them to a post-processing process such as an inspection department. It is configured.

The above-mentioned supply section (tan) will be explained based on FIGS. 2 and 3. In this supply section (11), a supply chamber (13) and a suppressing plate (14) as a pressing body are arranged on the front side of a vertical substrate (10) shown in FIG. The press plate (14) is configured to move up and down by a press plate operating mechanism (and), and the paper sheets (P) and paper sheets (P) supplied to the supply chamber (13) are
Push up upwards while supporting..., and apply a constant pressure to paper sheets (
P) is pressed toward the removal portion (12). That is, the press plate (14) is fixed to a slider (17) that is guided by a slide rail (16) so as to be movable up and down, and the slider (17) has a driving roller (
18) and an idle roller (19)... Both ends of a drive belt (20) are connected to each other. Then, the drive roller (18) is driven by a drive device (21).
), the suppressing plate (14) integrated with the slider (17) is raised or lowered by being driven in the forward direction shown by the solid line or in the reverse direction shown by the dotted line. The drive device ff (21) is composed of a motor, such as a speed control motor, whose rotational speed can be variably controlled.

Further, the horizontal portion of the suppression plate (14) on which the paper sheets (P) are placed has a portion in the direction in which the paper sheets (P) are taken out;
Push up the upper part (22) so that the part in the opposite direction is higher.
.

(23) is provided, and a recessed portion is formed in the central portion on which the paper sheet (P) is placed. The push-up part (22) functions to reliably press the tip of the paper sheet (P) on the take-out side to the take-out part (12), while the push-up part (23) acts as a press plate (
14) is designed to prevent the paper sheets (P) from coming together as they move (raise). In addition, the push-up part (2
3) is a suppression plate (14) that is composed of a leaf spring that is not very strong.
Since it is attached to the suppression plate (14), if there is a large amount of paper sheets (P)... placed on the suppression plate (14), the paper sheets (P)...
It is elastically deformed by the weight of ... and becomes almost horizontal. Then, the paper sheets (P) are taken out one by one, and as the remaining paper sheets (P) become less, the spring return force of the leaf spring reliably presses the remaining paper sheets (1') with an appropriate pressing force. Raise the paper sheet (P) to the take-out section (12).
It is now possible to push up.

Furthermore, on the rising direction side of the suppression plate (14) which is moved up and down by the suppression plate actuation mechanism (river), the position and presence of paper sheets (P) are detected to determine the rising speed and stoppage of the pressure plate (14). A sensing device (24) is provided that sends a signal to optimize the position and control the drive of the extractor (, 4). That is, there is a lever (25) on the upward direction side of the press plate (14).
is rotatably supported around a fulcrum (26), and its free end comes into contact with the ascending paper sheet (P). The lever (25) is always biased counterclockwise by its own weight or a force such as a spring (not shown) so that the free end side is the inclined lower end, and the pivot end side of the lever (25) is An angle detector (
For example, a potentiometer) (27) is provided. Note that (28) and (29) are guide members for stacking paper sheets CP) in an aligned state, and (30) is a mounting member for attaching the detection device (24).

To explain the control configuration using the angle detector (27), first, when a paper sheet (P) is placed and a take-out start button (not shown) is pressed, the press plate (14) rises and removes the topmost sheet. Class (P)
comes into contact with the lever (25). Then, as shown in Fig. 3, the angle A of the lever (25) at this time is detected by the angle detector (
27) reads and sends a signal to the drive device (21). Upon receiving this signal, the rotational speed of the drive device (21) is changed to a low speed, and the rising speed of the press plate (14) is reduced to such an extent that the sheet (P) does not generate inertia. Then, in that low speed state, the suppression plate (14
) and the paper sheets (P)... rise, the uppermost paper sheet reaches the take-out starting position. At this time, the angle detector (27) detects the angle B of the lever (25) shown in Fig. 3 and sends a stop signal to the drive device (21), and upon receiving this signal, the drive device (21) stops. . That is, the pressing plate (14) and the sheet (P) stop rising. Furthermore, the take-out section (12) is driven by this signal. Here, the take-out start position is 1 for the take-out part (12).
It is set at the center of the optimal pressing force range for taking out sheets one by one, and the angle of the lever (25) at this time is B. Furthermore, the upper and lower limits of the optimal pressing force range are set for the pressing force, and the lever angle at the upper limit of the optimal pressing force range is C, and the lever angle at the lower limit of the optimal pressing force range. is set as D. When the pressing force is between the lower limit of the optimum pressing force and the center of the optimum pressing force, the angle detector (27) detects that the lever angle is between D and B. Then, the angle detector (27) sends a command to the drive unit fit (21) to increase the pressing force until it reaches the center of the optimum pressing force range (until the lever angle reaches B).
). Further, the driving device (21) is configured to stop when the pressing force is at the center of the optimum pressing force range.

The take-out unit (12) detects the take-out start signal using the angle detector (27).
When received from the paper sheet (P) on the suppression plate (14)...
The paper sheets (P) are sequentially taken out one by one by the take-out section (12) starting from the top sheet (P). At this time, the suppression plate (14) is stopped, but as the paper sheets (P) are taken out, the number of paper sheets placed on it decreases, so the lever (25) follows this decrease. ) rotates counterclockwise.

When the angle of the lever (25) is between B and 0, raise the suppression plate (14) until the lever angle becomes B, and if it rises too much, the angle of the lever (25) becomes the angle between B and C. When this is the case, the suppression plate (14) is controlled to be lowered until the lever angle reaches B, and the paper sheet (P) is then taken out. Since the paper sheets (P) are taken out one by one, the suppression plate (14) rises while moving up and down little by little, and when all the paper sheets (P) are taken out, the lever ( Since the lever (25) and the suppression plate (14) are configured to nest together, the lever (25) rotates counterclockwise and returns to the original position A. The angle detector (27) is connected to the lever (2
5) has returned to its original position, and based on this signal, the drive of the extractor (12) is stopped and the drive device (21) of the press plate actuating mechanism (Dan) is controlled to rapidly rotate in reverse for a certain period of time. be done. That is, the press plate (14) rapidly descends.

With the above configuration, this device handles paper sheets (P) and the take-out section (
12) is set at the center of the optimal pressing force range for always taking out paper sheets (P) one by one,
One sheet can be taken out reliably. Also, after setting the angle detector (27), perform the take-out operation,
The output signals Vc and Vd of the angle detectors (27) at the upper and lower limits of the optimum pressing force range are electrically read, and as shown in Fig. 3, the intermediate value vb of these outputs is the optimum pressing force. A reference value is electrically set so as to be at position B. At this time, the analog signal from the angle detector (27) is sent through the A/D converter (31) to be converted into a digital signal, and this amount of displacement is displayed on the display section (32). By providing such a display section (32), there is no need for a special display device, and the time required for setting the reference value can be shortened.
7) by always displaying the value.

This reduces the amount of time required to find the cause and restore normal state when there is a problem with ejection.

In this embodiment, a device in which the pressing plate rises has been described, but the present invention is not limited to this, and a device as shown in FIG. 4 can be considered. That is, the drive roller (
Paper sheets (P) are placed on a conveying device (40) formed by winding a belt (43) around a driven roller (41) and a driven roller (42). ), and a pressing member (45) is provided at the other end.
44) is provided with a lever (46) and an angle detector (47), and the suppressing member (4) is actuated by a signal from the angle detector (47).
5) and a device for driving and stopping the transport device (40), the A/D converter (48) and its displacement amount are displayed on the display (
By adopting the configuration shown in 49), the effects of the present invention can be fully achieved.
