Description

  The present invention relates to a paper feed system that determines and manages the presence or absence of paper feed misalignment (paper feed failure).

  Conventionally, when creating slips, invoices, and the like, a form creation apparatus as shown in FIG. 1 is used. Such a form creation apparatus includes (a) a form creation unit and (b) a paper feed unit. , (C) an envelope insertion portion, and (d) an inspection portion. Here, in particular, in the (b) paper feeding unit, a paper feeding device that feeds paper one by one is used. In such a sheet feeding device, a defect is a sheet feeding failure. For example, the following three methods are used as methods for detecting the sheet feeding failure.

(I) Method of detecting a paper feed failure using the length and number of sheets When using the length of a sheet, measure the length of the first sheet fed to the sheet feeding device, The length of the first sheet is compared with the length of the second and subsequent sheets, and if the length exceeds the variation of the sheets, it is detected as a paper feed failure. However, there is a problem that it is necessary to follow up when the length of the first sheet of paper is erroneously measured, which is troublesome. When the number of sheets is used, a predetermined quantity is set, the number of fed sheets is counted and compared, the number of sheets is managed, and a sheet feeding failure is detected. However, this method has a problem that it takes time and effort because it is necessary to determine the quantity of paper to be fed in advance and install it in the paper feeding device (see Patent Document 1).

(Ii) Method of detecting paper feed failure using paper thickness and transmittance If the paper thickness is thick, the method based on the paper thickness and transmittance is effective, but the paper thickness In the case of a thin sheet, the accuracy may be lowered, such as erroneous detection, and there is a problem that paper that can be detected is limited by this method.

(Iii) Method for detecting paper feed failure using a high-speed camera or image sensor When a high-speed camera is used, paper failure can be detected by imaging paper using a high-speed camera. This is not suitable because it requires long-time measurement and data storage, such as monitoring changes in the paper feed state over time, and there is a problem in that the installation space for the high-speed camera is limited. In addition, when an image sensor is used, there is a problem that the installation space of the camera is similarly limited, and measurement cannot be performed when the paper is out of the camera field of view.

  Further, even in the above three methods, it is not possible to monitor the paper feed state for preventing the paper feed failure, so it is not possible to prevent the paper feed failure (feed misalignment).

  Hereinafter, the calculation function and the determination function will be described in detail.

<Calculation function>
First, the timing (T) at which the feeding of the paper indicated by the timing information notified by the feeding start notifying unit is started and the feeding path indicated by the timing information notified by the feeding path left side passing notification sensor A time (Tx) required between the timing (T1) when the sheet passes through the portion where the left passage notification sensor is installed is calculated.

(Equation 1)
Tx = T1-T (1)
Next, the timing (T) when the feeding of the paper notified by the feeding start notifying unit is started and the portion where the feeding passage right passing notification sensor notified by the feeding passage right passing notification sensor is installed The time (Ty) required between the timing (T2) when the time passes is calculated.

(Equation 2)
Ty = T2-T (2)
<Judgment function>
FIG. 5 shows the relationship between the paper feed start notification count x and Tx, Ty, and FIG. 6 shows the relationship between the paper feed start notification count x and Ty-Tx. FIG. 7A is a diagram when the paper is normally fed, and FIG. 7B is a diagram when the feeding of the left portion of the paper is slow in the traveling direction indicated by the arrow. FIGS. 7A and 7C are diagrams in a case where feeding of the left portion of the sheet is early in the traveling direction indicated by the arrow, and FIG. 10D is feeding of the right portion of the sheet in the traveling direction indicated by the arrow. (E) is a diagram in the case where the feeding of the right portion of the paper is early.

(I) Concerning the sheet misalignment on the left side of the sheet First, the sheet feeding start timing (T) indicated in the timing information notified by the sheet feeding start notifying unit is notified by the feed passage left side passing notification sensor. The reference time (T ′) of the time required between the timing (T1) when the sheet passes through the portion where the feed passage left-side passage notification sensor shown in the timing information is installed is stored in the storage unit in advance. The reference time (T ′) is compared with the time (Tx) calculated by the calculation function described above, and the time (Tx) and the reference time (T ′) are the same (Tx = T ′). 5 is shown in a state where a graph indicating the time Tx and a straight line indicating the reference time T ′ intersect, as shown in FIG. 5, the left side of the feeding unit feeding the paper (left feeding belt) ) Shows that there is no delay in the speed. Therefore, as shown in FIG. 7A, it can be seen that the paper is normally fed. When the time (Tx) is longer than the reference time (T ′) (Tx> T ′), as shown in FIG. 5, the graph indicating the time Tx is above the straight line indicating the reference time T ′. It is shown in a certain state, and it can be seen that the speed of the left portion (left feeding belt) of the feeding section feeding the paper is delayed. Therefore, as shown in FIG. 7B, it can be seen that the sheet misalignment occurs in a form in which the left portion (upper portion in the drawing) of the sheet is lowered. Further, when the time (Tx) is shorter than the reference time (T ′) (Tx <T ′), the graph indicating the time Tx is shown in a state below the straight line indicating the reference time T ′. It can be seen that the speed of the left part (left feeding belt) of the feeding unit that feeds is fast. Therefore, as shown in FIG. 7C, it can be seen that the sheet misalignment occurs in a form in which the left portion (upper portion in the drawing) of the sheet is raised.

(Ii) Concerning the right sheet misalignment Next, the timing (T) at which the feeding of the paper notified by the feeding start notifying unit is started and the feeding path notified by the right passage notification sensor of the feeding path. The reference time (T ′) of the time required between the timing when the sheet passes through the portion where the right passage notification sensor is installed and (T2) is stored in advance (the same value as the reference time described above). The reference time (T ′) is compared with the time (Ty) calculated by the calculation means described above. When the time (Ty) and the reference time (T ′) are the same (Ty = T ′), As shown in FIG. 5, the graph showing the time Ty and the straight line showing the reference time T ′ are shown in an intersecting state, on the right side (right feeding belt) of the feeding unit feeding the paper. You can see that there is no delay in speed. Therefore, as shown in FIG. 7A, it can be seen that the paper is normally fed. When the time (Ty) is longer than the reference time (T ′) (Ty> T ′), as shown in FIG. 5, the graph indicating the time Ty is above the straight line indicating the reference time T ′. It is shown in a certain state, and it can be seen that the speed of the right portion of the feeding means feeding the paper is delayed. Therefore, as shown in FIG. 7D, it can be seen that the sheet misalignment occurs in the form in which the right portion (lower portion in the drawing) of the sheet is lowered. Further, when the time (Ty) is shorter than the reference time (T ′) (Ty <T ′), the graph indicating the time Ty is shown in a state below the straight line indicating the reference time T ′. It can be seen that the speed of the right portion (the right feeding belt) of the feeding section that feeds is fast. Therefore, as shown in FIG. 7E, it can be seen that the sheet misalignment occurs in a form in which the right portion (lower portion in the drawing) of the sheet is raised.

(Iii) Regarding sheet feeding deviation The timing (T) at which the feeding of the paper notified by the feeding start notifying unit is started and the feeding passage right passage notification sensor notified by the feeding passage right passage notification sensor The time (Ty) required between the timing (T2) when the sheet passes through the installed portion and the timing when the feeding of the sheet indicated by the timing information notified by the feeding start notifying unit ( (Tx) and the time (Tx) required between the timing (T1) when the sheet passes through the portion where the feed passage left passage notification sensor indicated by the timing information notified by the feed passage left passage notification sensor is installed. ) And Ty = Tx when Ty−Tx = 0 as shown in FIG. 6, and T2−T = T1−T according to equations (1) and (2). Therefore, the paper feed misalignment It can be seen that there is no inclination (the sheet has no inclination) (see FIG. 7A). In the case of Ty−Tx> 0, Ty> Tx and T2−T> T1−T according to the expressions (1) and (2), so the right part of the feeding unit that feeds the paper It can be seen that the speed of the (right feeding belt) is delayed. Therefore, it is inclined as shown in FIGS. 7 (c) and 7 (d). In the case of Ty−Tx <0, Ty <Tx and T2−T <T1−T according to Equations (1) and (2), so the left part of the feeding unit that feeds the paper It can be seen that the speed of the (left feeding belt) is delayed. Therefore, it is inclined as shown in FIGS. 7B and 7E.

  In this way, by comparing Tx and Ty, it is possible to determine whether or not there is a feeding deviation of the paper that has passed through the feeding path.

  The display unit 34 is a part that displays information related to the paper feeding deviation determined by the control unit.

  Specifically, the management apparatus is notified of timing information indicating the timing (the portion indicated by black in FIG. 9B) at which the sheet has passed through the portion where the feed passage right passage notification sensor is installed.

  Next, the management device receives the timing information notified by the feed start notification unit, the feed passage left passage notification sensor, and the feed passage right passage notification sensor (reception process) (steps S21 and S22). 23), the timing at which the feeding of the sheet indicated in the timing information notified by the received feeding start notification unit, and the timing indicated by the timing information notified by the feeding path left side passing notification sensor are indicated. Calculate the time required between the time when the paper has passed through the part where the left-side passage notification sensor is installed and the timing when the paper feed notified by the feed start notification unit is started. The time required between the timing at which the paper passes through the portion where the feed passage right passage notification sensor is installed notified by the passage right passage notification sensor is calculated (calculation step) (step) 24).

  Specifically, see the description of the calculation function of the management device.

  Next, by comparing the results calculated by the calculating means, it is determined whether or not there is a paper feed deviation that has passed through the feed path (determination step) (step S25).

  Specifically, refer to the description of the determination function of the management device.
