Abstract

PURPOSE:To improve the operability by feeding the paper sheet automatically after returning it to a hopper in case the paper sheet is hitched at the entrance of a feed part. CONSTITUTION:When a paper sheet 40 is hitched at the entrance of a feed part 32, a reverse part is controlled by a control part. Thus the sheet 40 is once sent back to a hopper and then fed again automatically. In this case, the operation of the reverse part can be repeated by the number of times set by a setting device.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION This invention relates to an automatic IJ) lie mechanism for a paper strip counting machine.

TECHNICAL BACKGROUND OF THE INVENTION AND PROBLEMS THEREOF Conventionally, there has been a system in which a large number of paper pieces are stacked and stored in a hopper, and these paper pieces are separated and discharged one by one by a paper feeder. Some hoppers have a reverse section at the bottom that returns the paper pieces to the hopper. On the other hand, the pieces of paper in the hopper are fed one after another, but if the tip of the piece of paper is bent or bent, it cannot be fed smoothly. If this state continues for a certain period of time, it is determined that there are no more pieces of paper in the hopper, and the power is turned off.

Therefore, each time the broken piece of paper must be returned to the hopper using the lever and restarted. This kind of operation is extremely troublesome, and when no one is around, the machine is left in a non-operating state for a long time. It should be noted that any folds or bends to some degree at the leading edge of the paper strips will be flattened when the paper strips are returned to the bottom of the hopper by the reversing section, unless the paper strips are severely curled.

Purpose of the Invention This invention has been made in view of the above-mentioned points, and provides a paper strip counting machine that automatically returns the paper strips and feeds them again when the paper strips are caught on the string or at the entrance of the feed section 9. The purpose is to hang automatic retry machine #a.

Summary of the Invention This invention separates and feeds a large number of pieces of paper stacked in a hopper one by one using a paper feeder, and during this process, a sensor counts the number of pieces of paper and detects the shape of a bent paper piece with a folded tip. When this occurs, the paper piece count signal from the sensor is interrupted because the paper piece is caught at the entrance of the paper feed section 9, but when the time reaches a certain value, the reverse section is operated for a certain period of time under the control of the control section and the paper piece is caught. The folded and curved pieces of paper are returned to the hopper to straighten out the folds and curves D', and the paper feeding operation continues at the same time as the renovating section stops, and the bent and bent pieces of paper cannot be simply returned once and fed. Since the machine may get stuck again, the system is configured so that the operation of the renosing section is repeated a desired number of times set by the setting device, so that the jammed paper υ can be disposed of automatically. O Embodiment of the Invention An embodiment of the invention will be described based on the drawings.

As shown in Figure 1, the front of the main body (1) includes a power switch (2), a keyboard (3), a counter display (4), a preset display (5), a completion lamp (6), and an error lamp ( 7) are arranged. It's small, there's a hole at the top,
(8) is formed, and a stacker (9) for storing paper pieces such as banknotes is provided at the bottom. Hola/< (8) A presser body ←a having all presser foots is attached so as to be movable up and down.

As shown in Fig. 2, an eccentric hopper roller (6) is provided at the bottom of the hopper (8), and a frame u9 holding the PR crawler '3 and presser plate 0 is connected to the reverse solenoid θG. It is fixed to a connected and rotating bin 07). PR crawler 1 is located at the back of the hopper (8).
A pair of left and right reverse rollers (1→) are provided facing each other at a predetermined interval.
And v birthlenoid αG and frame αG! The J-verse roller 08) is configured with a reverse section.

Further, behind the reverse roller (19), a paper feed roller and a roller (21) are arranged in the order of the conveyance path.
c) are joined. Further, at the back of the hopper (8), a power feeding block (C) is held so as to be rotatable about a fulcrum ee' while being biased counterclockwise by a spring (C). A feed block solenoid (C) is connected to the lower end of this feed block (C), and a stopper (1L) is connected to the upper end of the feed block (C). 8) An arc-shaped separation body (toward) is fixed to be connected to the paper feeding flora wire.

The hopper roller @, the reverse roller αυ, the paper feed flora kiln, and the roller OC are each connected to the zero center of the motor and rotate in a counterclockwise direction. Then, the υ paper feeding section O is operated by the conveying shear roller, the roller Cη, the feeding block (c), and the feeding υ block solenoid (b).
a is configured. The circumferential speed of roller H is faster than the circumferential speed of the paper feeding roller. Furthermore, a sensor 0→ is provided on the lower guide. Furthermore, a dip switch (b), which is a setting device, is provided at the bottom of the main body (1).

As shown in Fig. 4, the control unit CPU O$ is connected to RO
M@f9 and RAM (connected to 3'5. Also, the keyboard (3), the motor 0◇, the reverse solenoid OG, and the forwarding block renoid (Incorporated)
The sensor 09, the dip switch 04, the counter display (4), and the preset display (5) are connected to the CPU (3!3) via an i10 interface 00.

The keyboard (3) has a start key (2).

In such a configuration, the operation will be explained with reference to the four-chart shown in FIGS. 8 and 9. First, the keyboard (3
), turn on the start key G, and set the reverse solenoid Od to the number of repetitions ni.

This operation is shown in Figure 3 (α) when n = 1, Figure 3 (41) when n = 2, Figure 3 (0) when n = 3, and Figure 3 (0) when n = 4.
In this case, use the tip switch (b) as shown in Figure 3(d).
Switch. This tip switch 0 → signal is sent to the CPU
09 to set the number of operation repetitions n of the reverse solenoid αG. FIG. 9 is a flowchart for setting this n.

Then, the RAM (in the sheet number counter area 321, the sheet number counter becomes zero 7z, 9. Under the control of the CPU (c), the p motor 0 is turned on and the 9 feed 9 block solenoid) is turned on. When motor 0 is turned on, the hopper roller α, paper feed υ roller, roller Qυ, and reverse roller 0 rotate counterclockwise, and when the feed 9 block lens (b) is turned on, the feed υ block (c) is turned on. is the stopper (
The separator shaft rotates until it hits point C), and the separation body shaft approaches the paper feed sheet roller holder. Therefore, the paper pieces (/40) are intermittently struck by the eccentric hopper roller u2 and are sent to the left while slipping against the reverse roller α barrel.
Since the distance between the separator (a) and the paper feed roller holder is narrow in case 0, the lower sheet of paper is drawn in preferentially, and the upper layer of paper 0Q is drawn in later.

Next, a time count TCTR'i is set in the time counter area of the RAM (37). If the piece of paper OO is drawn in within 1 second at this moment i-, and the sensor 03 continues to turn on and then turns off, it means that the sensor (g) has counted one piece of paper 01, and 1 is added to the number of sheets counter. The number of sheets is displayed on the counter display (4), and this operation continues as long as there are paper pieces θO in the hopper (8). As shown in Figure 5, the bottom layer of paper 0 of Hotunoku (8)
If a fold or bend occurs at the tip of 0, the piece of paper 0Q will be caught at the tip of the separator. Therefore, time passes from the moment TCTR is set, but during that time r TCTR-I J,
rTcTR=o? J [Sensor 0 OFF? The processing and judgment of J are repeated 9 times. The processing time tpx for this one loop is 100 ps. Therefore, TCTR is 18/lp 1. In other words, if a loop that requires tpz is executed 10,000 times, 1 second will elapse.
rTCTR=O? YES is determined for J.

As a result, 1 is subtracted from the number of operation repetitions n of the reverse solenoid (161), and if "n=o?J" is determined to be NO, the reverse solenoid 00 is turned on.The time during which this reverse solenoid 00 is turned on. This is done by setting the time count TCTR in the time count area of the RAM.The processing of rTcTR-IJ and the determination of rTCTR=O?J are performed1.
Assuming that the loop processing time tp2 is 50 μs,
TCTR is set to 350 ms/lpz.

That is, TCTR is 700, and the reverse solenoid α0 is driven while the loop requiring tp2 is performed 700 times. As a result, the frame 09 rotates as shown in Fig. 6, and the lowermost piece of paper 01 is lifted up by the holding plate α4 away from the shuffling roller 0z, and the PR
The crawler 9 presses against the reverse roller 0υ. As a result, the paper piece θQ is returned to the hopper (8) and the upper layer paper piece θO
Scratches and scratches will be corrected. After 350m5 has passed, the reverse solenoid αG becomes 10FF.9.
Since PR crawler 9 leaves reverse roller 0→,
The paper feeding operation continues again as shown in FIG.

In this way, turn on the reverse solenoid αd while paper is being fed.
The operation of returning the piece of paper θO once and sending it again is repeated n times. In this embodiment, n is a maximum of 4 times. “n=
0? If it is determined to be YES for ``°, the feed block renoid (B) is turned off, and the feed block (C) returns until it hits the stopper (C) due to the force of the spring (C) and is separated. The body (a) separates from the feed roller and the motor 01) stops.

As described above, once a piece of paper QO is picked up at the entrance of the paper feed section 02, it can be returned to the holder (8)- and then automatically fed, resulting in extremely good operability.

Effects of the Invention Since the present invention is configured as described above, the reverse unit can be controlled by the control unit so that when a piece of paper is caught at the entrance of the paper feed section 9, the piece of paper can be returned once and then fed again. This is done automatically, and furthermore, the operation of the reverse portion can be repeated a number of times set by the setting device, and has the advantage of extremely good operability.
