Abstract

PURPOSE:To convey a prescribed number of sheets of paper through a simple operation immediately after paper jammed in a conveying passage is removed therefrom. CONSTITUTION:When a jam reset switch is pressed, a control section drives a conveying motor and puts a timer circuit into operation so that normal paper in a conveying passage is sent onto a receiving shelf and a second counter is caused by the output of a second sensor to perform incremental counting. When a timer-set time has elapsed, the count of the second counter is applied to a first counter, which is caused by the output of a first sensor to count the number of sheets of paper from a paper feeder, to modify the count of the first counter. When the operation of a sorter is resumed after removing jammed paper, the counts of both the counters are equalized to each other so that a prescribed number of copied sheets can be sorted without hindrance. According to this constitution, even if paper is jammed, sorting operation can be immediately resumed only by removing the jammed paper.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a sorter that feeds paper sheets from a paper supply device to a shelf by a predetermined paper tray. To provide a control device for a sorter that can easily continue to feed a predetermined number of sheets when a paper jam occurs and the jammed sheets are removed from a feeding path.

A conventionally known sorter device includes a paper supply device 1 and a sorter section 2, as shown in the explanatory diagram of FIG.
The paper (not shown) ejected from the conveyor belt 3
The paper enters a downwardly inclined paper feed path consisting of a conveyor belt and conveyor rollers 4, and then is fed horizontally through a paper feed path also consisting of a conveyor belt and rollers. At the end of the horizontal paper feeding path, there is a guide plate 5 for changing the direction of the paper being fed.
, the paper feed direction is changed upward.

Conveyor belt l-3, which conveys paper vertically upright, has a number of paper trays and shelves 6 installed diagonally along it, and on the conveyor belt side of each column, there are A gate plate 7 and a paper discharge port 8 are respectively provided for changing the feeding direction of the paper. The paper is fed upward through a paper feeding path consisting of a conveyor belt 3 and paper ejection rollers 8, and the feeding direction is sequentially changed by a gate plate 7 that operates from the top stage (or from the bottom stage). The paper trays are stored on the shelf 6. In addition, the sorter device is equipped with a first sensor 9 near the entrance of the paper feed path to detect the number of sheets fed and to detect the occurrence of a jam in the paper feed path, and a paper tray is installed on the shelf. A second sensor 10 is installed near the entrance of the sensor 6.

Further, an auxiliary sensor 11 is usually provided in the paper feeding path, particularly near the guide plate 5 where the paper feeding direction is changed. Note that the guide plate 5 for changing the paper feeding direction is
When the sorter section 2 is connected and expanded, the paper tray at the bottom (or the top) is flipped up by a signal from the switch that detects the operation of the gate plate 7 at the entrance of the shelf 6, and the paper is moved to the right side in the figure. The sheets can be fed toward the horizontal sheet feeding path of the added sorter section 2.

In order to control the operation of the sorter described above, a control device as shown in the block diagram in FIG. 2 has conventionally been used. In the figure, the part surrounded by the two-dot chain line is the control part,
The thick white arrow indicates the paper feeding direction, and the other arrows indicate the flow of signals.

Hereinafter, with reference to FIG. 1, the operation of the sorter by the control device shown in FIG. 2 will be explained. First, when the number of sheets to be fed by the sorter is input into the control section from the sheet number setting section equipped with an operating member such as a numeric keypad, the number of sheets to be fed is preset in the first and second counters, respectively. be done. Next, when a start button (not shown) is pressed, the transport motor and the paper supply device 1 are started, and the paper passes through the paper feed path one by one at regular intervals, and the paper receiver is fed to the shelf 6. Ru. At this time, the first sensor 9 located near the entrance of the paper feed path detects the leading edge of the paper passing through and sends a signal to the first counter to count the number of sheets. A certain second detector 10 detects the trailing edge of the passing paper and sends a signal to a second counter to count the number of sheets stored. When the paper passes normally through the paper feed path in the sorter and the paper tray is fed to the shelf, the count value from the signal sent to the first counter indicates the preset paper feed. When the number is reached, the first counter sends a stop signal to the control section, and the paper supply device 1 stops its operation according to the signal from the control section. On the other hand, the count value based on the signal sent to the second counter is
When the preset number of sheets to be fed has been reached, the second counter sends a stop signal to the control section, and in response to the signal from the control section, the conveyance motor that feeds the sheets moves until the gate plate 7 returns to its initial state. After that, the operation is stopped and the sorting operation is completed.

If the paper does not pass through the paper feed path normally as described above and a so-called jam occurs, the paper is stuck in the paper feed path, so if any sensor outputs a signal, the jam detection unit detects this abnormally long signal and sends a jam occurrence signal to the control section. Upon receiving the jam occurrence signal, the control unit immediately switches on the paper supply device 1.
stops the operation of the transport motor, and lights up the jam indicator lamp to warn the operator of the occurrence of a jam.

In such a case, the operator inspects the sorter, removes the jammed paper in the paper feed path, presses the jam reset switch, and resumes work, but as shown in Figure 2, Sorters incorporating conventional control devices cannot immediately resume work. This is because the counted values of the first and second counters in conventional control devices are always smaller by the number of sheets of paper in the paper feed path during sorter operation, and the second counter is always smaller by the number of sheets of paper in the paper feed path during sorter operation. By removing , this difference becomes even larger. Therefore, if the work is restarted without any change, the count value of the first counter reaches the preset number of paper feeds and the paper supply device 1 stops. On the other hand, since the count value of the second counter is insufficient by the number of sheets removed due to the jam, the paper tray does not feed paper into some of the shelves 6, and furthermore, the conveyance motor does not match the count value of the second counter. Regardless, the gate plate 7 will stop after a certain period of time (if the paper tray into which no paper is sent is left in the position of the shelf).

Therefore, in the case of the conventional device, the operator has to perform the troublesome work of checking the paper shelves to which no paper has been fed and replenishing the paper to each shelf by hand, and then moving the gate plate 7 for the next operation. I had to restore it to its initial state. In addition, if a jam occurs immediately after the start of sorting work, the jammed paper will be removed, and the paper tray will remove all the paper that has already been sent to the shelf and the paper in the paper feed path, and then After that, I had to perform the inefficient sorting process all over again from the beginning.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide sorter control that allows the user to easily resume work without the above-mentioned effort after a jam occurs in the paper feed path and the jammed paper is removed. to provide equipment;
Particularly, this effect is fully demonstrated in a sorter device (2) in which a plurality of sorter sections 2 are connected and added.

FIG. 3 is a block diagram showing the configuration of the control device for the sorter of the present invention. Each arrow in the diagram has the same meaning as in FIG. 2, but the signal flow in the part indicated by the thick black arrow is This is the main part that characterizes the invention.

In the sorter control device of the present invention, if a jam occurs in the paper feed path and an abnormally long signal is input from one of the sensors to the jam detection section, a jam occurrence signal is sent to the control section, and the control section Immediately stopping the paper supply device 1 and the conveyance motor and lighting up the GILEME indicator lamp is exactly the same as in the conventional device. In this case, there is a difference between the count value in the first counter and the count value in the second counter, and the count value of the first counter is always larger than that of the second counter. It is the same as the conventional device.

However, in the sorter control device of the present invention, after a jam occurs in the paper feeding path and the paper feeding device 1 and the conveyance motor stop, the paper stuck in the feeding path is removed and the paper is reset. When the switch is pressed, the signals are processed in the control unit in the following order. First, the control section receives the signal from the jam reset switch.
A start signal is issued to the transport motor, and the paper tray feeds the normal paper remaining in the paper feed path into the shelf. After some time has elapsed for this purpose, the control part reads the count value in the second counter, transfers this value to the first counter, and modifies the count value that was previously in the first counter. Then, the count values in the first and second counters are made the same value. Thereafter, the control unit issues a start signal to the paper supply device to restart the operation of the sorter device. When the operation of the sorter device resumes, the count values in the first and second counters are the same as described above, so unless a jam occurs again, the count value in the first counter will remain in the counter. When the preset number of paper feeds is reached, the first counter sends a signal to the control section, and the control section issues a stop signal to the paper supply device to stop the paper supply. Similarly, when the count value of the second counter reaches the preset value due to a paper feeding error, the second counter sends a signal to the control unit, and the control unit issues a stop signal to the transport motor, causing the transport motor to stop. and avoid stopping all sorter equipment operations.

As is clear from the above explanation, in the sorter control device of the present invention, no matter how many sheets of paper stuck in the feed path are removed when a jam occurs, the control section is reset by the signal from the jam reset switch. performs the signal processing described above and starts the paper supply device after making the counts in both counters the same value, so when the preset counts such as the number of paper feeds match, the sorter The machine stops and the paper tray feeds the paper correctly to the shelf. The sorter control device of the present invention includes a sorter section 2
It is especially effective in large-capacity sorter equipment in which multiple units are connected and expanded. In other words, in such devices, there are many opportunities for jams to occur because the paper feeding path is long, and the number of paper feeds preset in the counter is also large, so once a jam occurs, If several sheets of paper are removed from the feed path, conventional control devices require significant effort to restart the operation. On the other hand, in the control device of the present invention, the signal from the second sensor 1o provided in the added sorter section 2 is also input to the second counter in the control section, and is integrated as a count value in the second counter. Therefore, as mentioned above, the count value in the first counter is corrected to the same value as the accumulated count value in the second counter by the signal from the jam reset switch, so there is no need for any trouble when restarting work. It requires no consideration either. Note that the paper supply device 1 may be a dry type electronic copying machine, and if the start switch of the copying machine is appropriately connected to the control device of the present invention, there will be no trouble when a jam occurs in exactly the same way as described above. A predetermined number of copies can be sorted.

As explained above, in the sorter control device of the present invention, the signal processing as described above is performed in the control section according to the signal from the jam reset switch.
If a jam occurs in the paper feed path, you can immediately resume work by simply removing the jammed paper in the feed path. It is extremely effective in equipment. Furthermore, the electronic circuits that make up the two counters, the control section, and the jam detection section in the control section of the Mokkomei can be integrated into one circuit using integrated circuit technology, which increases the reliability of device operation, eliminates malfunctions, and makes assembly easier. This also makes it easier and lower costs.

Detailed Description of the Invention The present invention relates to a control device for a sorter that feeds sheets of paper from a paper supply device to a shelf, and more specifically, to prevent irregular feeding of sheets in a paper feed path. An object of the present invention is to provide a sorter control device that allows a predetermined number of sheets to be easily continuously fed when a paper jam (hereinafter referred to as a jam) occurs and the jammed paper is removed from a feeding path. . A conventionally known sorter device includes a paper supply device 1 and a sorter section 2, as shown in the explanatory diagram of FIG.
The paper (not shown) ejected from the conveyor belt 3
The paper enters a downwardly inclined paper feed path consisting of a conveyor belt and conveyor rollers 4, and then is fed horizontally through a paper feed path also consisting of a conveyor belt and rollers. At the end of the horizontal paper feeding path, there is a guide plate 5 for changing the direction of the paper being fed.
, the paper feed direction is changed upward. Along the conveyor belt 3, which conveys sheets of paper upward, which are vertically erected, a large number of paper trays and shelves 6 are installed diagonally. , a gate plate 7 and a paper discharge roller 8 for changing the paper feeding direction. The paper is fed upward through a paper feeding path consisting of a conveyor belt 3 and a paper discharge port 8, and the feeding direction is sequentially changed by a gate plate 7 that operates from the top stage (or from the bottom stage). Each paper tray is stored on a shelf 6. In addition, the sorter device is equipped with a first sensor 9 near the entrance of the paper feed path and a paper receiver (printer) to detect the number of sheets being fed and to detect the occurrence of a jam in the paper feed path. A second sensor 10 is installed near the paper feed path 116. Furthermore, an auxiliary sensor 11 is usually installed in the paper feed path, especially near the guide plate 5 where the paper feed direction is changed. Note that the guide plate 5 that changes the paper feeding direction is located at the lowest stage (
or the top shelf) is located on the gate plate 7 at the entrance of the shelf 6.
It jumps up due to the signal from the switch that detects the operation of the
The paper can be fed toward the horizontal paper feeding path of the sorter section 2, which is added on the right side in the figure. In order to control the operation of the sorter described above, a control device as shown in the block diagram of FIG. 2 has conventionally been used. In the figure, the part surrounded by the two-dot chain line is the control part,
The thick white arrow indicates the paper feeding direction, and the other arrows indicate the flow of signals. Hereinafter, with reference to FIG. 1, the operation of the sorter by the control device shown in FIG. 2 will be explained. First, when the number of sheets to be fed by the sorter is entered into the control section from the sheet number setting section equipped with an operation member such as a numeric keypad, the number of sheets to be fed is displayed in the first and second counters. Each is preset. Next, when a start button (not shown) is pressed, the transport motor and the paper supply device 1 are started, and the paper passes through the paper feed path one by one at a constant (i!l) interval, and the paper tray is moved to the shelf 6. At this time, the first sensor 9 located near the entrance (=J) of the paper feeding path detects the leading edge of the passing paper and sends a signal to the first counter to count the number of sheets. The paper tray is located near the entrance of the shelf 6. A second sensor 10 detects the trailing edge of the paper passing by and sends a signal to the second counter. When the paper passes normally through the paper feed path in the sorter and the paper tray is fed to the shelf, the count value based on the signal sent to the first counter is equal to the preset paper When the number of feeds reaches the number of feeds, the first counter sends a stop signal to the control unit, and the signal from the control unit causes the paper feeding device 1 to stop operating.On the other hand, the count value based on the signal sent to the second counter , when the preset paper feeding error is reached, the second counter sends a stop signal to the control section, and the control section operates until the conveyance motor for feeding the paper returns Goo 1 to Board 7 to the initial state. After that, a stop signal is issued to stop the operation of the transport motor and the sorting operation is completed.If the paper does not pass through the paper feed path normally as described above and a so-called jam occurs, the paper will not pass through the paper feed path. Since it is stuck inside, if a signal is output from any sensor, the jam detection section detects this abnormally long signal and sends a jam occurrence signal to the controller 1 to the roll section.Jam'
Upon receiving the generation signal, the machine 1 to 1 unit immediately stops the operation of the paper feeder 1 and the transport motor at F9.
The jam indicator lamp is lit to warn the operator of the occurrence of jam A1. In such a case, the operator should check the sorter and remove any paper stuck in the paper feed path due to stains.
The user presses the jam reset switch and resumes work, but in the case of a sorter equipped with a conventional control head, such as the one shown in FIG. 2, work cannot be resumed immediately. This is because the counted values of the first and second counters in the conventional control device are always smaller by the number of sheets of paper in the paper feed path during sorter operation, and the second counter is always smaller due to the number of sheets in the paper feed path during sorter operation. This difference becomes even larger when the paper is removed. Therefore, if you restart the work without changing the paper feeding device 1, the paper feeding device 1 will stop when the count value of the first counter reaches the preset number of paper feeds, but the actual number of paper feeds will be Therefore, there is a shortage of paper by the amount removed, so paper will not be fed into some of the paper trays 6. moreover,
Although the count value of the second counter does not reach the preset value due to a paper feeding error and therefore does not issue a stop signal, the conveyance motor does not move the gate plate 7 to the paper that is not being fed, regardless of the count value of the second counter. When the receiver is placed on the shelf, it will stop after a certain period of time due to another circuit in the control section. Therefore, in the case of the conventional device, the operator has to perform the troublesome work of checking which paper shelves have not received any paper and manually replenishing the paper to each shelf, and then move the gate plate 7 for the next operation. In addition, if a jam occurs immediately after starting the sorter operation, remove the paper that is stuck in the jam (this is the paper tray). The inefficient work of removing the paper that has already been sent to the shelf and the paper in the paper feed path, and then starting the sorting operation all over again from the beginning was unavoidable.Therefore, the present invention has been made. The purpose of the present invention is to provide a sorter control device that can easily resume work without the above-mentioned labor and effort after a paper jam occurs in the paper feed path and the jammed paper is removed. The 31st ffl is the configuration of the control device of the sorter of this Komei. 2, each arrow in the figure has the same meaning as in FIG. 2, or the signal flow indicated by the thick black arrow is the main feature of the present invention.The sorter of the present invention In the control device, if a jam occurs in the paper feed path and an abnormally long signal is input from one of the sensors to the jam detection section, a jam occurrence signal is sent to the control section, and the control section immediately removes the paper. It is exactly the same as the conventional device to stop the supply device 1 and the conveyance motor and to turn on the jam indicator lamp.At this time, there is no difference between the count value in the first counter and the count value in the second counter. However, in the sorter control device of the present invention, there is a difference in that the decrement value of the first counter is always larger than that of the second counter. occurs, and after the paper feeder 1 and the transport motor stop, remove the paper stuck in the feeding path and press the jam reset switch. Signals are processed in the control unit 9 in the following order. First, the control section receives a signal from the jam reset switch and issues a start signal to the transport motor, causing the paper tray to feed the normal paper remaining in the paper feed path into the shelf. After a certain period of time required for this has elapsed, the control unit reads the count value in the second counter, transfers this value to the first counter, and corrects the count value previously in the first counter; The counts in the first and second counters are set to the same value. Thereafter, the control unit issues a start signal to the paper supply device to restart the operation of the sorter device. The signal processing within the control section described above will be further explained in detail with reference to flowchart 1 shown in FIG. First, when the switch 1 is pressed and the signal is input to the control section, the control section sends a start signal to the transport motor (step 14), and also starts a timer circuit that measures the fixed time required for paper feeding. Start operation. Is the transport motor made 8'? 1', the normal paper remaining in the paper feed path is fed into the receiving path, and when the second sensor detects the trailing edge of the paper (step 15), the count value of the second JR counter is (step 16).During this time, a jam may occur again, so the jam detection section constantly checks each sensor, and if any sensor outputs an abnormally long signal. When the jam occurs (step 17), a jam occurrence signal is sent to the control unit (step 18), and the control unit issues a stop signal to the conveyance motor as described above, and
Turn on the jam indicator lamp. Step 1: When the paper is fed normally and a certain period of time set by the tamper circuit in the control unit has elapsed.
9), move on to the next step. In the next step, the control unit first checks whether the counts of the first counter and the second counter are equal (step 20). When the count value of the double-edged counter has a phase, the count value of the second counter is transferred to the first counter, the il value of the first counter is corrected, and the count values in both counters are made the same value. (Step 21). Thereafter, the control unit issues a start signal to the paper supply device 1 (step 22), and restarts the operation of the sorter device. Once the operation of the sorter device resumes, the count values in the first and second counters are the same as described above, so unless the jam occurs again, the count values in the first counter will be the same. When the count value reaches the preset paper feeding error in the counter, the first counter sends a signal to the controller 1 to the roll section, and the control section emits a stop signal to the paper feeding device to stop the paper feeding. Avoid stopping.Similarly,
When the count value of the second counter reaches the preset number of paper feeds, the second counter sends a signal to the roll section, and the counter sends a signal to the roll section. Illuminate the motor with a light source, stop the conveyor motor, and stop the sorter device from operating. As is clear from the above explanation, Sorta III of this defense
In the control device 1 and J5, no matter how many sheets of paper stuck in the feed path are removed when a jam occurs, the control section performs the signal processing described above in response to a signal from the jam reset switch, and ]The paper feeding device is started after setting the count value in the counter to the same value.
When the preset number of paper feeds matches the counted value, the sorter device stops and the paper tray correctly feeds the paper to the shelf. The sorter control I device of the present invention includes:
This effect is particularly effective in a large-capacity sorter device in which a plurality of sorter units 2 are connected and expanded. In other words, something like this!
At the loading stage, the paper feeding path becomes long, so jams tend to occur (there are many jams, and the value of the number of paper feeds preset in the counter is also large, so it is necessary to
If this occurs and some sheets are removed from the feed path, conventional control systems require significant effort to restart the operation. On the other hand, in the control device of the present invention, the second sensor 1 provided in the expanded sorter section 2
Similarly, the 0 signal is input to the second force "Kunta" in the control section,
Since the count value is accumulated in the second counter, the count value in the first counter is corrected to the same value as the accumulated count value in the second counter by the signal from the jam reset switch as described above. Therefore, no effort or consideration is required when resuming work. Note that the paper supply device 1 may be a dry type electronic copying machine, and if the start switch of the copying machine is connected to the control device of the present invention (as appropriate), it can be used to prevent problems in the event of a jam in the same way as described above. As explained above, in the sorter wholesale 11!a device of this invention, the jam reset switch force is used to set the above-mentioned number of copies in the control section. If a jam occurs in the paper feed path, remove the paper that is stuck in the feed path and immediately remove it. This has the effect that it can be restarted without any extra effort, especially when using a large-capacity sorter (
It is extremely effective here. Furthermore, since the electronic circuits constituting both counters, the control section, and the jam detection section in the control section of the present invention can be made in one chip by using integrated circuit technology, the reliability of the device operation is increased (this also prevents malfunctions). 4.
