Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet stacking device, and particularly to a paper sheet stacking device suitable for stacking and processing a large number of paper sheets in various states such as banknotes. 2. Related to Leaf Accumulating Device [Prior Art] Conventional devices of this type include, for example, Japanese Patent Application Laid-Open No. 1986-1.
A device disclosed in Japanese Patent No. 291369 is known. Considering that this device cannot detect the top edge of the stacked paper while the paper is being stacked,
Every time a certain number of sheets have been deposited, the stacking operation is interrupted and an operation is performed to align the upper ends of the stacked sheets.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration the processing time required when stacking a large number of sheets of paper in succession or when completing a series of stacking operations and preparing for the next stacking operation, and the automatic cash handling system When stacking a large number of paper sheets in succession, such as when loading or collecting banknotes, it is necessary to interrupt the stacking operation and align the top edge of the stacked paper sheets several times every time a certain number of paper sheets are stacked. ,
In addition, when processing banknotes, after the depositing operation for one transaction is completed, it is necessary to align the top end of the deposited banknotes in preparation for the next deposit process, which has the problem of long processing time. .

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in conventional paper sheet stacking devices, and to improve the position of the -h end of stacked paper sheets during stacking operation. In addition to making it possible to perform alignment, even when stacking a large number of paper sheets in various states in succession, there is no need to interrupt the stacking operation to align the top end of the paper sheets,
Once again, the series of deposition operations is over! The purpose of the present invention is to provide a paper sheet stacking device capable of completing the two-end alignment operation of the stacked paper sheets in a short period of time, and furthermore, this device is equipped with a paper sheet feeding mechanism. The purpose of the present invention is to provide a paper sheet processing device that can be used to process paper sheets.

[Means to solve the problem]

The paper sheet vibrates when it comes into contact with the guide member or collides with accumulated paper sheets during conveyance. Therefore, if you immediately give a descending instruction to the paper sheet storage section when the guide member is located at the second end of stacking of paper sheets, the paper sheet storage section will be lowered at one point before the sheets actually accumulate to the top end. , a problem arises in that the sheet stacking operation becomes unstable. Therefore, in order to solve this problem, the present invention has adopted the following configuration. That is, a confectionery conveying device, a stacking storage unit that sequentially stacks the limitedly fed paper sheets, and a moving means that moves the stacking storage unit along the direction in which the paper sheets are piled up. Rotation 11T due to contact with the paper sheets being carried in and the stacked paper sheets.
a guide member which is supported on a fixed side; an upper edge detection means which detects that the guide member is in contact with the top edge surface of the stacked paper sheets and generates an H signal; and 1. an output of the H signal. and a control section having a determination means for instructing an operation signal to the effecting means to lower the stacking storage section only when the above continues for a predetermined period of time or more. , and four, a paper sheet processing device is constructed in which a paper sheet feeding mechanism is provided.

[Effect]

The guide member is lifted up by the paper sheets in the advancing position until the paper sheets enter and are aligned at the stacking position, and after the paper sheets are aligned at the stacking position, the guide member is used to guide the stacked paper sheets. After coming into contact with the pile of paper, it rises again due to the reaction of colliding with the pile of paper, and after that, it collides with the pile of paper again, causing a damped vibration. Therefore, as described above, even if the sheet is not at the upper end stacking position, a detection signal indicating that the sheet has arrived at that position is generated. Therefore, in the present invention, if the time at which one end position is detected exceeds a certain predetermined time, it can be determined that the paper sheet has been deposited at the correct upper end position, rather than erroneous position detection due to vibration etc. as described above. do not have. Therefore, by lowering the paper sheet storage section only when the signal indicating that the guide member is at the desired position continues for a longer time than a predetermined time, the paper sheet storage section is lowered to prevent the paper sheet storage from being lifted by the entering bill of the guide member and from the effects of subsequent vibrations. It becomes possible to correctly (align) one end surface of the paper sheet 1 without having to do so.

〔Example〕

The embodiments of the present invention will now be described in detail based on the drawings.

FIG. 1 is a side view showing a sheet stacking apparatus according to an embodiment of the present invention. In the figure, the symbol 2 is 0, which is not shown.
? It is a conveyance means that conveys the paper sheets 1 from the 7th process to the paper storage section 3, which will be described later. A high-performance push plate 4 is provided and is configured to be moved by a motor 5 of the drive means.

Further, in the upper part of the paper sheet storage section 3, there is a fixed side support that guides the paper sheets 1 inputted from the transport stage 2 and is rotatable about point A so as to be in contact with the L end surface of the stacked paper sheets 1 channel. In connection with this, there is provided an L end detection step 7 using an optical sensor that detects the dark when the guide member 6 goes up and the light when it goes down.

The upper end detection stage B 7 is connected to a control section 8 described later,
It is connected to the motor 5 via a motor connector 9. FIG. 2 is a diagram showing the configuration of the control section 8. As shown in FIG.

The control unit 8 includes a judgment F stage 10 and an AND gate 1 for determining whether the output of the two-terminal intelligent stage 7 is longer than a predetermined time.
1, an oscillator 12 that generates a motor drive signal. The determining means 10 is configured so that if the output of the upper end detecting means 7 remains dark for a predetermined period of time, it then outputs ``H'', and when it switches to light, it outputs ``L''. Note that during the predetermined period of time, when the one end surface of the stacked paper sheet A is at the desired position and the output of the -1 one end detection bristle stage 7 is light, the paper clamp 1 enters and holds the guide member 6. :． From the time when the output of stage 7 becomes dark, the output of stage 7 becomes dark, and the guide member 0 contacts the -1 end of the stacked sheet 1a again, and the output of stage 7 becomes light. The value is set to 1 until the specified time. More specifically, the time period is set to be at least longer than the time during which vertical vibrations are occurring in the guide member 6 due to the entry of paper sheets or collision with accumulated paper sheets. For the following explanation, it is assumed that the predetermined time is "1" from the time T0.

Next, the operation of this embodiment configured as described above will be explained based on FIGS. The operation explanatory diagrams, FIGS. 4 and 5, show time charts of the control section 8.

FIG. 3(α) shows the moment when the conveyed paper sheet 1 is held by the guide member 6 and the output of the upper end detection means 7 changes from light (light {) to dark (r.).

In FIG. 3(b), a sheet of paper is in the middle of entering the sheet storage section 3, touches the guide member 6 and pushes it, and the seventh edge detection means 7 becomes dark (I...). ing.

Figure 3 (c) and note (note) show the state after time r1 from the state shown in Figure 3 (o), in which the sheets 1 are aligned at the stacking position. At this time, as shown in FIG. 3(.), if the end surface of the stacked sheets 1a is lower than the desired position -h<1j, the output of the upper end detection stage 7 is dark (l,
) to write (iI), the judgment is L stage].
0 is determined to be a case where the output of the upper end detection stage 7 becomes dark only due to the influence of the intrusion of the paper sheet, and the push plate 4 does not descend. A time chart in this case is shown in FIG. That is, from time T0? The guide member 6 is in a dark (L) state until ゛, and then the guide member 6 rises once again due to the reaction of colliding with the stacked paper sheet 1Q, and again collides with the stacked paper sheet 1 (I), causing damped vibration.During this period (T , to r2) is the judgment f
Stage 10 repeats counting start and resetting, but any dark signal reaches the set time T. Since the time is 1, and the predetermined time until the time is shorter, it is determined that the output of the end detection means 7 becomes dark (L) due only to the influence of the paper sheet, and the push plate is lowered. However, the vibration subsides after time T2 from the state shown in FIG. 3 ((L)).

' After time F1, the accumulated paper sheet 1 is deposited as shown in Figure 3 (a).
, if the upper end is higher than the desired top surface position,
The output of h#j detection stage 7 remains dark.

A time chart in this case is shown in FIG. After the time 'r■, the rear guide member 6 vibrates attenuated in the same manner as when the two ends of the stacked paper fJia are lower than the desired position.
The output of the upper end detection means 7 remains dark. After this, a predetermined time is determined from the state shown in FIG. ．． {Outputs a signal (shown at point B) and gate] The motor drive signal from the oscillator +2 is output from -1 and transmitted to the motor discharge section 9, and the motor 5 is driven.C The push plate 4 is lowered. Then, it stops at the point (T.+) where the second end detection stage 7 becomes light.

Furthermore, even if the next sheet 1 is fed before the output of judgment F stage 10 switches from H to r, the output of 1 end detection f stage 7 remains dark (l4). Since it is closed, there is no problem with the lowering operation.

Although not shown, the paper sheet stacking device shown in FIG. 1 may be provided with a paper sheet sorting mechanism and a paper sheet separating and feeding mechanism for separating and feeding out the accumulated sheets again. This allows paper sheets to be processed automatically and smoothly.

Specifically, the paper sheet processing device is widely used as a device for automatically processing Juzen banknotes.
