When the deceleration operation of the difference time between the actual arrival time and the theoretical arrival time is completed, the control unit sets the side belt 25 with the correction unit rail to the same speed as the rotation speed of the bottom belt 24 of the correction unit as shown in FIG. The rotation is returned to the constant speed, and the paper sheet 4 is supported by the first and second guides while being in contact with the first rail, and is conveyed for the conveyance time shown in FIG. 7B.

When the transportation of the paper sheets is completed and the side belt 25 with the correction section rail rotates by a distance of one pitch, the side belt 25 with the correction section rail stops and enters a standby state as shown in FIG. 9 (E). . At this time, the first side belt 25 of the correction unit
The positions of the first crossbar and the second crossbar are switched. Therefore, FIG.
As shown in FIG. 7, only the correction unit bottom surface bell 24 is in a rotating state.

Next, when the actual arrival time of the paper sheet 4 is longer than the theoretical arrival time (when the paper sheet 4 arrives later than the theoretical arrival time), the relationship between the paper sheet 4 and the side belt with the correction section rail Will be described with reference to FIG.

Before the paper sheet 4 reaches the correction unit 8, FIG.
As shown in FIG. 7A, in the standby state, the side belt 25 with the correction section is stopped, and as shown in FIG. 7C, only the bottom belt 24 of the correction section is rotating.

When the sheet 4 arrives at the correction section 8 and the correction section sheet position detector 16 detects the arrival of the sheet 4, a detection signal is sent to the control section, and the control section receives this detection signal. And the driving source is controlled to enter the operation start state shown in FIG.
As shown in FIG.
Starts. At this time, the speed of the side belt 25 with the correction section is equal to the speed of the bottom belt of the correction section.

The paper sheet 4 is first supported by the first and second guides and is conveyed at the rotation speed (constant speed) of the correction unit bottom surface belt 24, and as shown in FIG. 7 until the paper passes the correction unit paper sheet position detector 16.
As shown in (C), the sheet is conveyed at a constant speed that is the same as the rotation speed of the correction unit bottom belt 24.

When the sheet position detector 16 detects the passage of the sheet 4, the correcting section enters an acceleration operation state as shown in FIG. 10D, and the second crosspiece is moved to the rear end of the sheet 4. Accelerated to catch up.

A paper sheet length detector (not shown) for detecting the length of the paper sheet 4 in the conveying direction is provided in the upstream conveying section 6, and the paper sheet length detector is provided. The control unit calculates the length of the sheet reaching the correction unit based on the detection signal, calculates the amount of acceleration for the second rail to catch up with the rear end of the sheet, and further calculates the position of the correction unit sheet. The acceleration for compensating for the difference between the actual arrival time and the logical arrival time detected by the detector 16 is calculated, and the acceleration rotation speed of the side belt 25 with correction section rail is determined by adding (summing) these two accelerations.

In this way, as shown in FIG. 10C, when the paper sheet 4 passes through the correction unit paper sheet position detector 16, the conveyance of the paper sheet detected by the paper sheet length detector is performed. The length belt in the direction and the rotation speed for correcting the delay of the paper sheet are accelerated by the correcting section rail with side belt 25, and after the paper sheet 4 at the second rail as shown in the acceleration state of FIG. Press the end, Figure 7
It accelerates by the acceleration distance shown in (C).

When the acceleration operation is completed, the operation returns to the constant speed operation state as shown in FIG. 10 (E), and the rear end of the paper sheet portion 4 is kept in contact with the second rail, and the speed of the correction unit bottom belt 24 is the same. Returning to the constant speed operation state, as shown in FIG. 7C, the sheet is conveyed at the same constant speed as the correction unit bottom belt.

When the transport of the paper sheet section 4 is completed and the side belt 25 with the correction section rail rotates by a distance corresponding to two pitches, the side belt 25 with the correction section rail is stopped and enters a standby state as shown in FIG. . At this time, the correction unit returns to the original position of the first and second rails of the side belt 25 with the rail.

When the paper sheet 4 corrected by the correction section 8 reaches the downstream transfer section 9, the transfer section paper sheet position detector 1
7 detects that the paper sheet 4 has reached the transfer section 9.

Theoretically, after a certain period of time after the transfer box 11 has passed the transfer and swing trigger transfer box detector 19, the sheet 4
Can be transferred to the transport box 11 without acceleration or deceleration when the sheet passes through the transfer section paper sheet position detector 17, but the paper sheets are actually transferred to the transfer section paper sheet position detector 17 May pass through due to the movement speed of the transport box 11 or the delay of the paper sheet 4 generated when moving from the correction unit 8 to the transfer unit 9.

Therefore, similarly to the correction of the paper sheet 4 performed by the correction section 8, the transfer section 9 corrects the error by the side belt 27 with the cross section of the transfer section, so that the paper 4
Transfer.

The control unit measures the actual arrival time of the paper sheet 4 based on the detection signal of the transfer / oscillation trigger transport box detector 19, and determines whether the transport box 11 has the transfer / oscillation trigger transport box detector. 1
9 is compared with the logical movement time of the transport box 11 when a preset predetermined time has passed, and the movement of the side belt 27 with the transfer section rail is controlled as follows according to the comparison result.

When the paper sheet 4 arrives earlier than the theoretical value (theoretical arrival time) (when the actual arrival time is shorter than the theoretical arrival time), the paper sheet 4 is moved by the beam of the side belt 27 with the transfer section beam.
The transport time is adjusted by transporting while decelerating by pressing the leading end of the printer.

When the paper sheet 4 arrives later than the theoretical value (when the actual arrival time is longer than the theoretical arrival time), the end of the paper sheet 4 is accelerated by pushing the end of the paper sheet 4 by the rail of the side belt 27 with the transfer section rail. The transport time is adjusted by transporting while performing.

When the paper sheet 4 arrives at the transport time (theoretical arrival time) according to the theoretical value, the rail of the side belt 27 with the transfer section rail is rotated at the same speed as the transport speed so as not to contact the paper sheet 4. I do.

As described above, the movement of the side belt 27 with the transfer section rail is controlled by comparing the actual arrival time and the logical arrival time, similarly to the side belt 25 with the correction section rail.

The cross section of the transfer section cross section side belt 27 has been described as having two cross sections (a first cross section and a second cross section) arranged at predetermined intervals, similarly to the correction section cross section side belt 25. However, a third bar and a fourth bar may be arranged between the first bar and the second bar.

When the transfer box 11 passes through the transfer box detector 19 for the transfer swing trigger, the transfer plate 9 synchronizes with the movement of the transfer box 11 and moves the base plate 29 to a predetermined position in a horizontal direction with a predetermined position as a fulcrum. The amplitude fluctuates. Transfer section 9 and transport box 11
Swings in synchronization with each other, the relative speed between the paper sheet 4 to be transferred and the input portion of the moving transport box 11 becomes zero, and the paper sheet 4 is transferred to the transport box 11 during this time.

As described above, in the first embodiment, the transport box 1
1 is detected by the supply start trigger transport box detector 18 disposed in the sorting / stacking section 2 and reaches the position opposite to the transfer opening which is the transfer start position, and the paper sheet 4 is supplied. The papers 4 placed on the single feed unit 5 of the supply unit 1 are arranged so that the time from when they reach the transfer port, which is the transfer start position, is Box 11 detected by the transfer box detector 18 for use
Are fed one by one based on the passage information of the sheet, and are transported at a constant speed in the supply unit 1 without stopping the flow of the transport of the paper sheet 4 and passed through the transport box detector 18 for the supply start trigger. Since the sheet is transferred to the transfer box 11 by the transfer unit 9, the transfer speed of the sheet is improved.

Further, if the transport time of the paper sheet 4 is disturbed during the transportation, the correction unit 8 can correct the transportation time, so that the paper sheet 4 does not stop during the transportation and the transport processing speed of the paper sheet can be improved. Is improved.

Further, the shift of the timing at which the paper sheet 4 passes through the transfer section paper sheet position detector 17 is corrected in the same manner as the correction section 8, so that the transfer of the paper sheet 4 to the transport box 11 is performed. Loading can be performed more reliably.

Further, the transport section 6 in the supply section 1, the elimination section 7,
The correction unit 8 and the transfer unit 9 do not need to stop the flow of the paper sheet 4 during the conveyance, and thus do not need a mechanism for holding the paper sheet 4 such as a pinch roller as in the related art.

Each of the transport unit 6, the elimination unit 7, the correction unit 8, and the transfer unit 9 having a block has a bottom belt and a side belt, and each bottom belt is inclined at a predetermined angle with respect to the horizontal direction. Are disposed, and each side belt is disposed perpendicular to each bottom belt. One end of the paper sheet 4 abuts on the bottom belt, and the paper sheet 4
Can be processed with a wide variety of paper sheets 4 (thickness, hardness, shape, etc.) and paper sheets of different sizes (height, width). it can.
Therefore, besides the paper sheets, for example, the CD stored in the case
Also, books, catalogs, etc. can be transported.

Further, since the sheet 4 is not stopped or supplied while holding the sheet 4 by a pinch roller or the like as in the prior art, no load is applied to the sheet 4 and there is no risk of damage.

Next, a second embodiment of the present invention will be described with reference to FIG.
This will be described in detail with reference to FIG. It is a timing chart which shows the timing of supply start.

In the first embodiment, when the transport box 11 has passed the transport start detector 18 for supply start trigger, the control unit starts supply based on the detection signal sent from the transport start detector 18 for supply start trigger. A signal is generated to control the rotation of the suction belt 14 of the one-feed unit 5 by a predetermined distance. That is, a detection signal of the transport box detector 18 for supply start trigger and a supply start signal for controlling activation of the suction belt 14. Is in phase, but the transport box that moves in the sorting / stacking section basically moves at a constant speed, but the transport speed varies depending on the amount of paper being transported and the environment (mainly temperature). It is possible to do.

If there is a change in the transport speed, the paper 4
There is a difference between the time when the transfer box 9 is conveyed to the transfer section 9 and the time when the transfer box 11 moves to a position facing the transfer port of the transfer section 9. Class 4
The amount of adjustment of the transfer time becomes large.

Thus, for example, the actual moving time during which the transfer box 11 moves from the supply start trigger transfer box detector 18 to the transfer swing trigger transfer box detector 19 is measured. By comparing it with the theoretical time and applying the feedback to the supply start signal,
A supply signal corresponding to the speed change of the transport box is given,
Absorbs the speed change of the transport speed.

As described above, in the second embodiment, the actual movement time in which the transfer box 11 moves from the supply start trigger transfer box detector 18 to the transfer swing trigger transfer box detector 19 is set in advance. Since the time difference from the theoretical time is fed back to the supply start signal, the supply start signal corresponding to the change in the speed of the transport box can absorb the change in the transport speed of the paper sheet 4. In addition to the effects of the example, a new effect of improving the supply timing accuracy can be obtained.

[0114]

As described above, the first embodiment of the present invention has the following effects.

The first effect is that the processing speed is improved. The reason is that by controlling the supply of the paper sheets based on the movement of the transport box, the paper sheets are transferred to the transport box without stopping the flow of the paper sheets being supplied.

The second effect is to enlarge the sheets to be processed. The reason is that the conveyance of the paper sheets is supported and conveyed by a bottom belt having a certain angle with respect to the horizontal and a side belt arranged perpendicular to the bottom belt.

The third effect is that there is no damage to paper sheets. The reason for this is that there is no sudden acceleration or deceleration while pinching the sheet by a pinch roller or the like because the flow of the sheet is not stopped.

The second embodiment has the following new effects in addition to the effects of the first embodiment.

This is to improve the accuracy of the supply timing of paper sheets. The reason is the actual moving time of the transport box 11,
By feeding back a time difference from a preset theoretical time to the supply start signal, it is possible to absorb a change in the transport speed of the paper sheet.
