Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet transport processing device, and particularly to a paper sheet transport processing device that allows paper sheets to be reversed in a switchback manner during transport. The present invention relates to a paper sheet processing device having a reverse feeding function.

[Conventional technology]

As a method for reversing the sides of paper sheets from one side to the other, for example, as described in Japanese Patent Application Laid-Open No. 59-212855, a reversing case is provided in the middle of the conveyance path of the paper sheets, and one sheet is turned over. There is a switchback reversing mechanism that once sucks the sheets into the reversing case, collides with the path stop member, and then pulls the sheets back into the next conveyance path from the rear end. In such a switchback reversal mechanism, the path stop member is fixed.

In the case of a moving structure that is controlled by the length of paper sheets in the conveying direction,
There are cases where it is an elastic support or a movable weight.

[Problem that the invention seeks to solve]

In the above conventional structure, if the course stop member is fixed,
Paper sheets of different sizes in the transport direction cannot be smoothly reversed. Moreover, when the position of this path stop member is controlled by the length of the sheet in the conveying direction, it cannot be applied to sheets that are skewed.

In addition, if the path stop member is made of an elastic support or a movable peg, and the pressing force on the path stop member is automatically changed according to the length of the paper sheet in the conveying direction, it is possible to Moreover, when the lengths in the conveying direction are the same and only the stacking direction, that is, the length in the width direction of the paper sheets differs in the conveying direction, the pressing force cannot be changed.

As described above, the conventional technology does not take into consideration the paper sheets that are skewed, and there are problems such as damage to the paper sheets that are reversed and an increase in the reversal time delay.6 The purpose of the present invention is to The objective is to smoothly reverse even skewed paper IRs and paper sheets having different lengths in the transport direction.

[Means for solving problems]

The above-mentioned purpose is to provide a detection device that detects the length and orientation of paper sheets that have been transported in the transport direction, and a control that controls the position of a paper sheet stop member of a switchback reversing mechanism based on signals from the detection device. Equipped with a device, if the conveyed paper sheet is skewed at the position of the path stop member, it is controlled to match the angle, and after reversing, the degree of skew is corrected. This is achieved by preventing malfunctions in the paper sheet processing section after reversal.

[Effect]

With the above configuration, the path stop member matches the shape of the leading edge of the paper sheet to be reversed, that is, the degree of skew, so there is no problem such as damage when stopping the paper sheet, and there is no problem with the technology. Reduction of reversal time delay, since it can be corrected
Problems in the post-processing section can be prevented.

【Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is a main roller, 1' is a reversing roller, 2 is an auxiliary roller on the sheet entry side, 3 is an auxiliary roller on the sheet ejection side, 4 is an upper reversing case, 5 is a lower reversing case, 6 is a path stop member,
Reference numerals 7a and 7b are control bars for controlling the path stop member 6, 8a and 8b are sensors for detecting the length of paper sheets in the conveying direction and the degree of skew, and 9a, 9b, 10a and 10b are holding rollers. Reference numeral 11 indicates paper sheets to be reversed, reference numeral 12 indicates a control bar control device, and reference numeral 13 indicates a sorting gate. This division gate 13
is rotated to the position shown by the solid line or to the position shown by the two-dot chain line depending on the direction of the paper sheet being conveyed. In addition, in this embodiment, when reversing one sheet, the position shown by the solid line is
If reversal is not required, it is rotated to the position shown by the two-dot chain line.

The paper sheet 11 is moved from the arrow part 14 to the nipping rollers 9a and 9b.
The length of one paper sheet 11 in the transport direction and the degree of skew are detected while the paper sheet 11 is being held and transported by the sensors 8 a e 8 b. The signal is immediately transmitted to the path stop member 6 by the control device 12, and depending on the degree of skew of the paper sheet 11 and the length in the conveying direction, for example, in FIG. If side 11a is leading.

By pulling the control bar 78 downward, the path stop member 6 and one side (Ill 11a) of the leading edge of the paper sheet 11 are controlled to be parallel to each other, and at the same time, one side 11a of the leading edge of the paper sheet 11 is controlled. At the same time as the other side collides with the course stopping member 6, one side lid of the trailing trailing end of the sheet 11 collides with the main roller 1 as the main roller 1 and the reversing roller 1' rotate. The control bars 7a, 7 are disengaged from the belt 15 and moved in the direction of the auxiliary roller 3.
It has a structure that controls the position of b.

Both sides 11a and llb of the leading edge of the paper sheet 11 collide uniformly with the entire course stopping member 6, and after the paper sheet 11 has stopped,
By driving the control bars 7a, 7b, the course stop member 6 is moved to the position 6' in FIG. 2, that is, parallel to the axis of the main roller 1. In this way, the paper sheets 11 that have entered the reversing case in a diagonal manner during one reversal are stopped by the path stop member 6.
By controlling the position of the roller by driving the control bars 7a and 7b, the oblique trajectory can be corrected and the roller can be conveyed parallel to the main roller axis.

With the above configuration, even if the paper sheets have different lengths in the transport direction, for example, even if the paper sheets are curled or folded, the apparent length in the souvenir transport direction is shorter. In addition, even if the sheet is conveyed obliquely, the position of the path stop member 6 can be freely controlled according to the conveyance state of the sheet, so that the switchback reversal operation can be performed smoothly. be.

Also, during the switchback reversal operation, both sides 11. In order for a and llb to collide uniformly, paper sheets 11
It is possible to prevent scratches and breaks due to stress concentration, which are likely to occur when there is uneven contact on both sides 11a and 11b of the tip. Further, after the paper sheets 11 have stopped once, the path stop member 6 can push the paper sheets 11 in the direction of the auxiliary roller 3, so that the paper sheets remain in the reversing cases 4 and 5. There's nothing wrong with that.

In the second embodiment, the positions of the sensors 8a and 8b are not limited to these positions as long as the conveyed sheets pass through before colliding with the path stop member.

In FIG. 1, when there is no need to turn over the paper sheets, the paper sheet sorting gate 13 is rotated from the position shown by the solid line to the position shown by the two-dot chain line, and the paper sheets are moved from the arrow 14. It is transported along arrows 16 and 17.

Therefore, if, for example, bills with both front and back sides mixed are conveyed one by one from the direction of the arrow 14, the sorting gate 13 is rotated to the position shown by the solid line only when conveying back notes. By rotating the banknotes to the position 13' only in this case, when the respective banknotes are conveyed to the position indicated by the arrow 17, it is possible to make all the front and back sides of the banknotes uniform.

In this way, the paper sheet processing device of the present invention can convert paper sheets with mixed front and back sides into paper sheets with all fronts and backs aligned, so that it can be used, for example, in the automatic teller machine shown in FIG. Built-in and used. The automatic teller machine is equipped with a deposit/withdrawal port 19 on the front side of a main body 18 of six machines that handle banknotes as paper sheets. A separating device 21 for taking in deposited banknotes 20 is provided on one side of the deposit/withdrawal port 19, and a pushing plate 23 for pushing out paid banknotes 22 into the deposit/withdrawal port 19 is provided on the other side. A banknote discrimination unit 24 is provided in the center of the main body 18, and it determines the authenticity of the banknotes 20 and 22 to be taken in or dispensed, the number of denominations 2, front and back, and the number of banknotes 20 and 22.
At the rear part of the main body 18, there is a front/back reversing section 25 shown in FIGS. The impeller stack section 27 has a first denomination box 28 for recycling banknotes, a second denomination box 29 at the bottom of the main body 18, a collect box for collecting unidentifiable banknotes, and a receiving banknote box. A safe 31 is provided for temporary storage of banknotes 20 or for supplying and collecting banknotes at the start and end of work. Said first denomination box 28. Second denomination box 2
Impeller stack parts 32 and 33 are provided on the upper part of 9, respectively.
Further, the separating device 35 for separating and taking out the banknotes 34 in the first denomination box 28 and the separating device 37 for separating and taking out the banknotes 36 in the second denomination box 29 are connected to the safe 31.
Each of the 0 or more parts, each of which is provided with a separating device @39 for separating and taking out the banknotes 38 inside, is connected by a conveying means, and a dividing gate is provided at a branching part in the conveying means.

In the above-mentioned automatic teller machine, the banknotes 20 inserted by the customer into the deposit/withdrawal port 19 for deposit are generally taken out from the wallet, so the banknotes 20 have both front and back sides mixed.
In the discrimination section 24, only those items that are determined to have the 'J& orientation are transported by the front-back reversing section 25 to be reversed, and all of them are aligned face-up and placed in the safe 3 by the temporary stacking section 26.
After temporarily storing the money in the upper part of 1, the money is stored in a first denomination box 28, a second denomination box 29, and a transfer box 30 for items not used for withdrawal.

In addition, the banknotes 34 or 36 stored in the first denomination box 28 or the second denomination box 29 can be paid out to the deposit/withdrawal port 19 according to a customer's withdrawal request.

In the embodiments described above, a method is shown in which the front and back sides are reversed by the front and back reversing unit before temporary stacking at the time of deposit, but it goes without saying that the present invention can be applied to a method where the front and back are reversed at the time of withdrawal.

If the switchback front/back reversing mechanism of the present invention is applied to the front/back reversing unit of the automatic teller machine described above, it will be possible to prevent paper sheets from being damaged, or paper sheets that are skewed before being conveyed to the reversing mechanism. Since it is possible to correct the skew of paper sheets, the paper sheet processing device becomes stable and highly reliable.

〔Effect of the invention〕

According to the present invention, the leading edge of the paper sheet being reversed in switchback can be stopped by uniformly colliding with the path stop member, so that the paper sheet will not be damaged such as scratches or folds. . Further, for paper sheets that are conveyed in a skewed manner, the skew can be corrected and the sheet can be reversed. Further, for paper sheets having different lengths in the conveyance direction, it is possible to perform a smooth reversal operation by controlling the position of the path stop member. In addition, a series of reversing operations such as temporarily stopping the paper sheets and reversing and feeding them can be performed smoothly depending on the condition of the paper sheets, which has the effect of preventing paper sheets from accumulating during reversing. be.
