CONSTITUTION:Sheets thrown from a feed part into the subject device pass a shift sensor 43 after the surfaces thereof have been detected by a sheet surface detecting means not shown herein. In this case, normal and reversed sheets are classified with the transverse shift of a gate member 41, and respectively pass a normal sheet carrier passage 1 and a reversed sheet carrier passage 3, finally accumulated on an accumulation part 59 with the sheet surface directions unified. In the course of the aforesaid process, when upper surface sensors 45a and 47a, and lower surface sensors 45b and 47b have detected the specified total number of passed sheets, separators 49a and 49b distinguish the specified number-th (100th) of sheets from a succeeding sheet (101st), thereby preventing the accumulation of sheets exceeding the specified number on the accumulation part 59.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Purpose of the Invention (Industrial Application Field) This invention aims to collect a specified number of paper sheets such as abrasive coins, which have both front and back sides, by aligning them in one direction. This invention relates to a stacking and sorting device for paper sheets that roll.

(Prior art and its problems) In general, this type of stacking and sorting device needs to accurately stack the specified number of paper sheets, which are continuously conveyed without cutting, in the stacking section before sending them to the next process. At the same time, there is a need for a technology that reliably allows the front and back sides to be printed one at a time in the stacking section.

However, none of the conventional devices particularly satisfies this requirement, causing problems in the accumulation of paper sheets.

This invention was made by focusing on such conventional problems, and it is a stacking system of ff1 leaf force 1 that ensures that the front and back sides of paper sheets are aligned and that the specified number of paper sheets can be stacked in the stacking section. The purpose is to provide a sorting device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve this object, the present invention provides a front-back detection means for detecting the front and back sides of paper sheets input with both front and back sides during transportation, A human conveyance path and an actual conveyance path are provided in which the front and back paper sheets detected by the front/back detection means pass separately to align the front and back sides of the paper sheets, and the human conveyance path and the @conveyance path are provided. a stacking section for stacking a predetermined number of paper sheets with the front and back sides aligned; a paper sheet detection means for detecting the number of paper sheets is provided on each of the human transport path and the actual transport path; , a separator is provided for separating the predetermined number of 'd1 sheets from subsequent paper sheets by detecting a predetermined number of paper sheets accumulated in the stacking section by each of the paper sheet detection means; did.

(Function) In such a configuration, after the front and back detection means detects the front and back sides of paper sheets that are input with both front and back sides mixed, the front paper sheets and the double-sided paper sheets are separately routed through the human transport path and the actual transport path. They each pass through the stacking section, where the front and back sides are aligned and stacked. In this process, when the paper sheet detection means detects the total number of paper sheets that have passed by the specified number, the separator separates the specified number of sheets from the subsequent sheets, and transfers the specified number to the stacking section. Prevent the accumulation of more than

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

The attached drawing shows the main parts of the paper sheet accumulation and sorting device.
Paper sheets input into the apparatus from a paper sheet supply section (not shown) are detected by a front/back detection means (not shown), and then the paper sheets are placed in a symmetrically arranged human eye feed path 1. j3 and the actual conveyance path 3.

The human transport path 1 includes a first front roller 13a, a second front roller 15a, a third front roller 17a, and a fourth front roller 19.

ii The transport route 3 is the first one arranged symmetrically with respect to the human transport route 1
It is formed between the first back belt 29b and the second back belt 35b, which are wound around predetermined rollers from the center roller 13b to the tenth back roller 33b.

Immediately before the first front and back rollers 13a and 13b, rollers 37 and 39 for supplying to each conveyance path 3 and 5 are provided, and furthermore, a shift sensor 43 for moving a gate member 41, which will be described later, is provided immediately before that. It is being When the shift sensor 43 detects a paper sheet, the gate member 41 moves to the left when the detected paper sheet is the front side and guides the front sheet to the human feed path 1, and conversely moves to the right side when the detected paper sheet is the front side. to guide the paper sheets on the back side to the actual conveyance path 3.

Fourth front roller 19a of front and rear conveyance paths 1 and 3
and the fifth front roller 21a and the fourth back roller 1
9b and the fifth back roller 21b, a first front hinge 45a and a first back sensor 45b are provided, respectively, as paper sheet detection means for detecting paper sheets during conveyance each time they pass. Also, the sixth front roller 23a and the seventh

A second front sensor 47a and a second back sensor 47b, which are similar to the first front and center sensors 45a and 45b, are provided between the second front roller 25a and the seventh back roller 25b, respectively.

Paper sheets are each of the above-mentioned senna 45a, 45b, 47a.
, 47b, the counter is incremented to a specified number. Among these, when the total number of paper sheets detected by the first front sensor 45a and the first top sensor 45b reaches the specified number (for example, 100 sheets) and the second front sensor 47a and the second back sensor 47b When the total number of paper sheets is 1 in 101 if the specified number of sheets is 100, the fourth front door-519a,
A front separator 49a and an I separator 49b, which will be described later, rotate around the fourth back roller 19b to separate the specified 22nd sheet from the subsequent sheets.

The first front roller 19a and the fourth real roller 19b are respectively attached to a front separator shaft (not shown) and a male bar nota shaft via external bearings. The front and back separator shafts are interlocked and connected to the front and back separators (not shown) which are composed of pulse motors, and are supported by bearings at both ends (not shown). Further, the front and back separators 49a and 49b are directly connected to the front and back separator shafts, and their rotational positions are controlled by the front and back separator motors.

Furthermore, front position sensor heights 51a, 52b1 and position sensors 51b and 52b are provided around the fourth front roller 19a1 and the fourth back roller 19b, respectively, for checking the rotational positions of the front separator 49a1 and the back separator 49b.

Side walls 53 and 55 facing each other are provided near the fourth front roller 19a and the fourth side roller 19b,
A backup portion 57 is provided between the side walls 53 and 55 so as to be movable forward and backward.

Surrounding this backup section 57 are five paper sheet accumulation sections. The backup section 57 is linked to a control motor 63 via an L-shaped bent arm 61, and is moved up and down by the operation of the motor 63 to transport the designated number of sheets to a tertiary process. In addition, this control motor 6

It operates to lower 7.

Eccentric rollers 65.67 are mounted on both sides of each side wall 53.55.
rotates in contact with each side wall 53.55, which constantly vibrates the side wall 53.55 and
The stacked paper sheets on 7 are well aligned.

Front and rear separators 49a and 49b are each sensor 45a
, 45b, 47a, and 47b rotate approximately 180 degrees after detecting the specified number of sheets, but after the specified number of sheets (
When the 101st sheet of paper passes through the front sensors 45a and 47a, the front end of the front separator 49a is slightly above the back separator 49b, and the front end of the front separator 49a is slightly higher than the back separator 49b, while the front side sensors 45b and 47b
When passing through, the tip of the actual separator 49b is placed slightly above the front separator 49a. This allows the next designated number of sheets to smoothly enter onto each separator 49a, 49b.

Thereafter, the separators 49a and 49b are both in a horizontal state with no difference in level. Also at this time, both separators 49
The tips of the separators 49a and 49b intersect, thereby preventing paper sheets from entering between the separators 49a and 49b.

Therefore, both separators 49a and 49b have a comb-like shape. Furthermore, both separators 49a and 49b have a predetermined thickness, so when they rotate approximately 180 degrees and come to the stacking section 59 in order to separate the designated number of sheets and thereafter, the backup section 57 has a predetermined thickness. The control motor 63 is rotated so as to lower it by a certain amount.

The thickness of each of the above-mentioned separators 49a and 49b is approximately half that of the fourth front roller 19a and the fourth real roller 19b, and is offset in the direction of rotation thereof. Thereby, when each separator 49a, 49b rotates to the position of the stacking section 59, paper sheets can be easily placed on the separators 49a, 49b.

Next, the operation of the thus configured accumulating and sorting device will be explained.

In the initial state, the front and back separators 49a and 49b are on standby immediately below the entrance sides of the front and back conveyance paths 1 and 3, respectively.
Furthermore, the backup section 57 is arranged at a height where it can easily receive paper sheets entering the five stacking sections (see FIG. 1).

Paper sheets input into the apparatus from a paper sheet supply section (not shown) have their front and back sides detected by a front/back detection means (not shown), and then pass through the shift sensor 43. At this time, the paper sheets detected by the front/back detection means If leaves are detected as the front side, gate member 4
1 moves to the left in the figure. As a result, the paper sheets pass through the front conveyance path 1 and enter the five stacking sections on the backup section 57.

Further, when the paper sheet detected by the front/back detection means is detected as the inside, the gate member 41 moves to the right side and the paper sheet passes through the back yρ feed path 3 and enters the five stacking sections. As a result, the paper sheets that have passed through each conveyance path 1.3 are reliably aligned with their front and back sides in the five stacking sections.

In this way, the paper sheets are sequentially accumulated in the five stacking sections, and the paper sheets are sent to the first front sensor 45a or the first back sensor 45b.
When the specified number of sheets < 100 sheets) is detected and the second front sensor 47a or the second top sensor 47b detects the next sheet after the specified number of sheets (the 101st sheet), a separator motor (not shown) is activated. Then, the front separator 49a rotates counterclockwise in the figure, and the back separator 49b similarly begins to rotate clockwise.

Hereinafter, the discussion will proceed on the assumption that the 100th and 101st sheets of paper pass through the attenuation feed path 1. At this time, as shown in FIG. 2, after the 100th paper sheet P100 passes through the front separator 49a, the front separator 49a protrudes above the decaying feed path 1 and the 100th paper sheet P+
oo and the 101st paper sheet P+ o + are separated. At this time, the back separator 49b is also rotating at the same time, and continues to rotate at the same time as the front separator 49a thereafter.

Thereafter, when the 100th paper sheet P100 enters the five stacking sections and the front and back separators 49a and 49b are further rotated to the state shown in FIG. 3, the control motor 63 is activated and the backup section 57 descends and conveys the bundle of 100 sheets to the next process (see Fig. 4). At this time, the tip of the front separator 49a is connected to the back separator 49.
The 101st sheet 101 is located above the separator 49a and 49b so that it can easily enter the separators 49a and 49b.

For the 101st and subsequent sheets, the paper sheets sent from the actual image conveyance paths 1 and 3 are first conveyed to the next process after the bundle of 100 sheets on the backup section 57 is conveyed to the backup section again. 5
7 is returned to the accumulation section 59, the front and actual image separators 4
9a and 49b (see FIG. 5). When the backup section 57 returns to the five accumulation sections, each separator 49
498a and 49b further rotate in the same direction as they have been rotating and return to the standby position (see Figure 6), and the paper sheets accumulated on the front and back separators 498 and 49b are backed up. 57, and the above operations are repeated.

In the above operation, the front and back separators 49a.

The back separator 49b rotates to follow the direction in which the paper sheets pass, so there is plenty of time for them to pass through the front and front transport paths 1.3.

Since the operation time of the separators 49b can be slowed down, it is possible to rotate the front and back separators 49a and 49b even with a small power source.

Note that this invention is not limited to the above-described embodiments. For example, instead of providing a pair of separators on a front and a back side, they may be provided on only one side if a large operating area can be obtained. Further, the sensor that detects the 101st sheet may not be provided.

[Effects of the Invention] As described above, according to the present invention, it is possible to reliably align the front and back sides of paper sheets that are supplied with both fronts and backs mixed, and it is also possible to accurately accumulate a specified number of sheets in the collecting section.
