Description

  The present invention relates to a technical field related to display of an on / off state of a detection function of a paper feed error detection means in a paper supply apparatus.

In the paper supply device, an error may occur in the paper supply operation in the paper supply unit.
Error types include double feed, idle feed, and paper jam. Double feed means that two or more sheets should be fed one sheet at a time from the paper feed shelf, and empty feed means that paper is fed from the paper feed shelf when paper should be fed. The paper jam is a case where the paper feeding operation is started but the paper is jammed before the paper is completely fed out.

When such an error occurs, the sheet supply apparatus cannot be operated as it is, and therefore it is necessary to stop the operation of the sheet supply apparatus.
For this reason, conventionally, the paper supply device is provided with a paper supply error detection means for detecting a paper supply error in the paper supply unit.
That is, when the paper feed error detection means detects a paper feed error, the paper feed operation of the paper supply unit is automatically stopped based on the detection signal.

This paper feed error detection means is provided at the front end of the paper feed of the paper supply unit, irradiates the light beam of the light emitting element from one side of the paper surface, and receives the light transmitted through the paper on the other side by the light receiving element. A paper feed error is to be detected based on the received light intensity during the passage time for one sheet.
That is, when the transmission / reception intensity of one sheet continues for the time passing through the sheet detection means is normal, it is determined that the paper is jammed when the transmission / reception intensity continues beyond the sheet passage time, and the sheet transmission / reception intensity at the passage time is determined. Is weaker than the received light intensity transmitted through one sheet of paper, it is determined to be a double feed (for example, refer to Patent Document 1).

However, since the paper feed error detection means is based on the above principle, there is a case where it is determined as an error even though there is no paper feed error.
For example, if the paper is black solid printing, the transmitted light intensity decreases even if one sheet is judged to be double feed, or if the paper is thin paper, the transmitted light intensity is the same as when no paper is present, and the feed is skipped. If there is dust or paper debris on the paper feed error detection means or if it is out of order, it is judged that the paper is jammed. Operation may be stopped.

  Therefore, as an operator, there is no paper feed error when the paper is black solid, thin paper, or dust or paper debris is attached to the paper feed error detection means. In order to prevent the paper feeding operation from being stopped, the paper feeding device is operated with the paper feeding error detecting function of the paper feeding error detecting means turned off for the time being.

However, the indication that this detection function is turned off is not displayed on the operation start standby state display section of the paper supply device, and the paper feed error detection function on / off display is in the operation start standby state. A further screen had to be called from the display screen (according to the applicant's practical experience and interviews).
JP 2002-72776 A (paragraph [0003], FIG. 1)

  As described above, the indication that the paper feed error detection function is turned off is not displayed on the operation start standby state display section of the paper supply device. Therefore, when the operator of the device changes, the subsequent operation The user does not realize that the previous operator was operating with the paper feed error detection function turned off, restarts the operation of the device, and then the paper supply device automatically stops even if a paper feed error occurs There is a problem in that it continues to operate without being discharged, and a sheet stack with overlapping pages or missing pages is discharged.

  In addition, when the paper supply device has a large number of paper supply units, such as a collation device, naturally, the number of paper feed error detection means provided in each paper supply unit also increases, and there are multiple types of paper feed error detection means. Paper feed errors (double feed, idle feed, paper jam), for example, the feed detection and jam detection functions are turned on and off at once, but the double feed detection function is turned on and off. There are cases where off is performed separately from the case of pre-feeding or paper jam, and there are cases where display information increases, and if the display space increases for each type, the display surface becomes large and expensive. For example, it is best to display on / off of a plurality of types of detection functions by changing the color in one display space for one paper supply unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the paper supply device of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram illustrating the configuration of an embodiment of a paper supply apparatus.
A bundle of sheets is stacked on the sheet supply unit 2 and is fed out one by one by a sheet feeding roller or a circular suction belt.
In this paper feeding operation, a known paper feeding error such as double feeding, idle feeding, and paper jam may occur. When such an error occurs, problems such as page overlap and page dropping occur in a sheet bundle formed by feeding paper.

  Therefore, in order to prevent such a situation from occurring, the paper supply status of the paper supply unit 2 is monitored by the paper supply error detection means 3, and if an error occurs, this is detected including the type of error, and the paper supply is detected. The operation is automatically stopped and the error occurrence and the type thereof are displayed on the paper feed error display unit 4. The maintenance staff or the operator looks at this display, eliminates the error and the cause of the error, and restarts the apparatus so that normal paper feeding is performed.

The paper feed error detection means 3 is turned on / off by a paper feed error detection function on / off setting means 5. This is because when the paper type is not suitable for error detection by the paper feed error detection means 3, or when there is a failure or other malfunction in the paper feed error detection means 3 itself, This is because it may be necessary to temporarily stop the function.
When the paper feed error detection function on / off setting means 5 is turned on / off, a signal indicating that is sent to the paper feed error detection function on / off display section 7 to display the on / off state of the detection function. .

In the present invention, this paper feed error detection function on / off display unit is displayed in the operation start standby state display unit 6. This operation start standby state display unit 6 is a screen that is displayed when the device starts operating when the start button is pressed, and items to be confirmed and checked when the device starts operating. Is a display unit on which is displayed.
Therefore, the fact that the paper feed error detection function on / off display unit 7 is in the operation start standby state display unit 6 indicates that the paper feed error detection function is turned on or off at the start of operation of the apparatus. This means that it can be confirmed without the need for switching screens.

If the paper feed error detection function on / off display unit 7 is not provided in the operation start standby state display unit 6 as in the prior art, the paper feed error detection function on / off display screen is called by screen operation. It is necessary to confirm. In this case, when there is a change in the operator of the paper supply device, the error detection function remains off after the previous operator continues to operate with the error detection function turned off for some reason. When the next operator tries to start the operation again, the error detection function is not displayed on the standby screen, so the error detection function is not remarkably turned on and off. It can happen to operate.
In this state, even if a paper feed error occurs, it is turned off, so that the paper feed error is not detected. Therefore, the apparatus continues to operate without being automatically stopped.

  In the present invention, as described above, the on / off display of the paper feed error detection function is performed in the operation start standby state display unit 6, so that the above-described inconvenience can be avoided.

  Since the paper supply unit 2 shown in FIG. 1 has many stages (for example, 12 stages) when the paper supply apparatus is a collating apparatus, the paper supply error detection means 3 also has a large number (12). . Since a plurality of types of errors are detected by a single paper feed error detection means, the display content of the paper feed error display section 4 including the on / off display of each function increases, so that some contrivance is required. .

FIG. 2 shows a paper feed error display unit 4 and a paper feed error detection function on / off display unit 7 displayed by the paper supply unit 2 in the operation start standby state display unit 6 of the 12-stage collating apparatus. is there.
In FIG. 1, the paper feed error display unit 4 is not included in the operation start standby state display unit 6, but FIG. 2 shows an example in which the paper feed error detection function on / off display unit 7 is included. .

The numbers in the left column indicate the rank order of the paper supply unit 2. On / off of the detection function is classified according to the color of the number and the color of the background of the number (square part).
Specifically, when the number color is black, the double feed detection function is on, when the number color is red, the double feed detection function is off, and when the background is light blue, the feed detection and paper jam detection functions are on. When the background color is purple, the idle feed and paper jam detection functions are turned off.
In other words, four states can be displayed by using colors for numbers and background.

Thus, the paper feed error detection function on / off display unit 7 can simultaneously display the on / off state of the detection function for each of a plurality of types of paper feed error categories.
A rectangular portion on the right side of the number field is a paper feed error display section 4 which displays the type of paper feed error with a stylized icon.
In the example in the figure, the first row icon indicates double feeding. The icon on the second row indicates skip feed. The third row icon indicates a paper jam.

FIG. 3 is a screen as a paper feed error detection function on / off setting means for turning on / off the error detection function of the paper feed error detection means 3, and (a) is a double feed detection function on / off setting screen. (B) is an on / off setting screen for the idle feed / paper jam detection function.
These screens are displayed by switching the paper feed error detection function on / off display portion 7 in FIG. 2, that is, by touching the portion where the number is displayed regardless of the numerical value. Whether to call (a) or (b) in FIG. 3 depends on the touch mode.
For example, (a) for a short touch (for example, less than 1 second), (b) for a long touch (for example, 1 second or more), (a) for a single touch, (b) for a double touch, etc. is there.
When the paper feed error detection function is turned on / off for only one type of paper feed error, it is not necessary to distinguish between the touch modes as described above.

The screen of FIG. 3 has 12 light bulb icon touch portions equal to 12 in the paper supply unit 2 of the collating apparatus 2 of FIG. 2 in both screens (a) and (b). This indicates that the error detection function is turned on for the paper supply unit in the numbered row shown on the left side of the touch portion, and indicates that it is turned off when the light bulb is extinguished.
As described above, both the double feed detection function and the idle feed / paper jam detection function can be turned on / off for each stage of the paper supply unit.

1 is a block diagram illustrating a configuration of an embodiment of a paper supply device of the present invention. FIG. 6 is a diagram illustrating an example in which a paper feed error detection function on / off display unit and a paper feed error display unit are displayed on an operation start standby state display unit of a collating apparatus which is an example of a paper supply device of the present invention. It is a figure which shows the screen which is an error detection function on / off setting means in case a paper supply apparatus is a collation apparatus.
