PURPOSE:To facilitate the supply of sheets without hindrance to the sheets by making sheets fed in a feed section into contact with a take-out means and a detecting means so as to detect the position and presence of the sheets in order to control the drive of a drive means, and by providing a rotatable means for limiting lateral movement of the sheets. CONSTITUTION:Paper sheets P fed in a supply sect on 11 are pressed in the surface direction by a pressing member 14, and accordingly, a take-out means 12 abuts against the forehead sheet P. Further, the sheets P are pressed against a detecting means 24 located in the vicinity of the take-out means 12 so as to detect the position and presence of the sheets P. Further, a rotatable guide member 28 for preventing lateral movement of the sheets P is provided on the side surface side of the sheets P. With this arrangement it is possible to reduce irregularities such as skew or the like upon take-out operation, irrespective of the number of sheets to be taken out, without hindrance during introduction.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a method for taking out paper sheets, in which securities such as checks and slips, or cards, etc. are set in a stack 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, sheets are 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, when pressing the stacked paper sheets against the ejecting section, if the paper sheets move to the side other than the ejecting direction due to the movement of the pressing plate, ejection failure will occur, so it is necessary to prevent this. was there.

Therefore, in the past, a fixed guide was attached to the paper sheet to control the movement of the paper sheet in a direction other than the direction in which it was taken out.

(Problems to be Solved by the Invention) Providing a fixed guide to prevent one sheet from moving laterally in a direction other than the direction in which the sheets are stacked in a conventional paper sheet take-out device As the number of sheets increases, the height of the fixed guide must also increase, so when feeding the press plate 18 sheets, the fixed guide becomes an obstacle, making it difficult to feed the press plate 18 sheets. A fixed guide with a low height has the disadvantage that only a small amount of paper sheets can be fed onto the suppression plate at a time.

The present invention has been made to solve the above problems,
When there are few sheets being fed onto the suppression plate, the movement is restricted by the fixed guide, and even when there are many sheets being fed, it is easy to move to the side other than the direction in which sheets are taken out. The purpose of the present invention is to provide a device for taking out filtered paper sheets that can be regulated according to the following conditions.

[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 drive means for moving the supply section toward the take-out means, and a drive means arranged near the take-out means and in contact with the foremost paper sheet to detect the position and presence of one sheet, thereby driving the drive means. and a rotatable guide body that is attached to the side surface of the paper sheets supplied to the supply section and guides the paper sheets while restricting their lateral movement. It is something that will be done.

(Function) In other words, the present invention has the above-mentioned configuration, so that regardless of the amount of filtered paper sheets supplied to the supply section, the entire side surface of the paper sheets is aligned by the guide body. It is possible to prevent failures in taking out. Furthermore, when feeding a large number of paper sheets to the supply section, the guide body can be rotated in a direction to retreat from the side of the paper sheets, so that the paper sheets can be easily fed without causing any obstruction to the paper sheets. be.

(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 supply section (11) will be explained based on FIGS. 2 and 3. A supply chamber (13) and a suppressing plate (14) as a pressing body are arranged on the front side of the vertical substrate (10) shown in FIG. The suppression plate (14) has a suppression plate operating mechanism (
) is configured to move up and down, supporting the paper sheets (P) supplied to the supply chamber (13) and pushing it upwards, and applying a constant pressure to the paper sheets (P). Removal part (,
It is pressed toward the U) side. That is, the pressure plate (14
) is fixed to a slider (17) guided by a slide rail (16) so as to be movable up and down, and the slider (17) has a middle portion wound around a drive roller (18) and an idle roller (19)... Both ends of the stretched drive belt (20) are connected. When the drive roller (18) is driven by the drive device (21) in the forward direction shown by the solid line or in the reverse direction shown by the dotted line, the suppression plate (14) integrated with the slider (17) rises or falls. It looks like this. Drive device (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 pressing 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 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 against the take-out part (12), while the push-up part (23) acts as a suppressor (
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 press plate (14), if a large amount of filter paper sheets (P)... are placed on the press plate (14), the paper sheets (P)
It is elastically deformed due to the weight of ... and becomes almost horizontal. Then, the paper sheets (P) are taken out one by one,
When the remaining paper sheets (P) are running low, the spring return force of the leaf spring reliably pushes up the remaining paper sheets (P) with an appropriate pressing force and puts the paper sheets (P) into the take-out section (12).
It is now possible to push up.

Furthermore, on the upward direction side of the suppression plate (14) which is moved up and down by the pressure plate operating mechanism (wear), the position and presence of a single sheet (P) is detected, and the rising speed and stoppage of the pressure plate (14) is adjusted. A sensing device (24) is provided that sends a signal to optimize the position and control the drive of the extractor (12). Moreover, (25) and (26) are guide members for stacking paper sheets (P) in an aligned state. In the figure, the fixed guide (2
7) is provided to prevent skew when taking out when the number of sheets is small, and the movable guide (28) is provided at the position shown in Fig. 1 when there is a large number of sheets to prevent skew and other problems. .

That is, the movable guide (28) is supported by the fixed part (29) and is rotatable around the fulcrum (30), and when the number of sheets to be taken out is small, it is rotated 90' to the position shown by the dotted line. They are supposed to be evacuated.

With this device, there are two methods: a method in which the number of sheets taken out at one time is small but taken out in a short cycle time, and a method in which the number of sheets taken out at one time is large but taken out irregularly. In the former case, paper sheets (P) are supplied to this take-out device from an automatic feeding device (not shown) in the direction (a) shown by the arrow. On the other hand, in the latter case, the movable guide (28) is obstructed during the supply because it is supplied manually.
Move the movable guide (28) 90 to the position shown by the dotted line in Figure 2.
By rotating and retracting it, it becomes possible to feed from the direction indicated by the arrow, and by returning the movable guide (28) to its original position, it prevents skewing and other problems in taking out paper sheets (P). It is configured so that it can be done.

With the above configuration, this device takes out paper sheets (P) and
When the number of paper sheets CP) is small, the movable guide (28) is in the retracted position, so the vertical movement of the suppression plate (14) is not obstructed, and the number of paper sheets CP) is large. In this case, the paper industry (P) is located at the position shown by the solid line in Figure 2.
・It is possible to prevent skew and other problems with ejection.

In this embodiment, a device in which the pressing plate rises has been described, but the device is not limited to this, and a device as shown in FIG. 3 has been considered. That is, the drive roller (3
1) and a driven roller (32) with a belt (33) wound around it. Paper sheets (I') are placed in an upright position on the conveying device (赳). A take-out portion (3A) is provided at one end, that is, the take-out side, and a suppressing member (35) is provided at the other end. In this case, the L-shaped movable guide (36) is placed in contact with the - side edge of the paper sheet (P), and rotated in the direction shown by the arrow using the pivot (37) provided at the end as a fulcrum. By adopting a movable configuration, the same effects as in the first embodiment can be obtained.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to reduce skew and other problems when taking out paper sheets without causing any trouble when feeding them, regardless of the number of sheets that are taken out. A take-out device is provided.
