Description

  In the present invention, an envelope paper having a pressure-sensitive adhesive applied to the side edges in the left-right direction is folded parallel to the left-right direction so that the pressure-sensitive adhesives face each other, and the side edges are pressure-bonded and sealed. The present invention relates to a sealed letter sealing device, and more particularly to a sealed letter sealing device in which the position in the left-right direction can be detected and adjusted so as not to cause a pressurization error at the side edge due to a positional deviation in the left-right direction of the paper.

  Patent Document 1 below discloses an invention of a sealing device that creates an envelope body by folding an envelope paper coated with pressure-sensitive glue and pressurizing the glue portion with a pressure roller. According to the present invention, when pressurizing both side edges in the left-right direction perpendicular to the conveyance direction of the envelope paper, if the left-right position of the envelope paper is deviated from the normal position, the envelope paper is correctly positioned with respect to the pressure roller. Since it cannot pass by, a crimping | compression-bonding defect will generate | occur | produce. Therefore, according to the present invention, the envelope paper can be fed to the pressure roller at the correct position by correcting the position of the paper feed table for supplying the envelope paper.

JP 2003-212218 A

  However, in the invention of Patent Document 1, even if the position of the paper feed table is adjusted, if the envelope paper is set apart from the paper feed table, the envelope paper is not supplied to the correct position with respect to the pressure roller. Defects will occur. In addition, in the case of an enclosing sealing device integrated with a printing press, if there is a deviation in the left-right position of the envelope paper that is printed and sent from the printing press, the envelope paper is also against the pressure roller in this case. Thus, it is not supplied to the correct position, and the crimping failure occurs similarly.

  That is, a general envelope paper is coated with a pressure-sensitive adhesive in a strip shape along the side edge in the left-right direction (that is, in the width direction). By folding the fold line, the pressure-sensitive adhesives on the side edges face each other, and by pressing between the side edges from above and below, the pressure-sensitive adhesive is caused to have an adhesive force and sealed. It is designed to create. For this reason, if the supplied envelope paper is misaligned in the left-right direction, it cannot be pressed with the edges on both sides of the folded envelope paper correctly sandwiched, and the sealed letter created due to insufficient pressure bonding There was a case.

  The present invention has been made in view of the problems as described above, and folds an envelope paper in which a pressure-sensitive adhesive is applied to the side edge in the left-right direction in parallel with the left-right direction, and pressurizes the side edge. An object of the sealing device for sealing is to prevent a press error at the side edge portion due to a displacement in the left-right direction, and to perform reliable sealing.

The sealed letter sealing device according to claim 1 is:
In a sealing and sealing device that seals a sealed letter by crimping after folding and adjusting the position of the envelope paper coated with adhesive on the side edges in the left and right direction,
A folding section for folding the supplied envelope paper in parallel with the left-right direction;

A sensor that is arranged upstream of the left-right position adjustment unit and detects envelope paper and outputs position data;
A storage unit that stores paper data indicating the position of the adhesive on the envelope paper corresponding to each type of envelope paper;
An input section for inputting the type of envelope paper to be used;
Paper data corresponding to the type of envelope paper input from the input unit is retrieved from the storage unit, and it is determined that a lateral displacement has occurred in the envelope paper based on the position data output by the sensor and the paper data. A control unit for controlling the left and right position adjustment unit,
It is characterized by having.

  According to the sealed letter sealing apparatus of the first aspect, the supplied envelope paper is folded in parallel with the left-right direction at the folding part, and the side edge adhesives face each other. The envelope paper is detected by a sensor, and position data is sent to the control unit. The control unit recalls the paper data corresponding to the type of envelope paper input from the input unit from the storage unit, and whether the lateral displacement of the envelope paper has occurred based on the position data from the sensor and the paper data. Judge whether or not. When the control unit determines that the lateral displacement has occurred in the envelope paper, the control unit controls the lateral position adjustment unit to adjust the lateral position of the envelope paper and send it to the crimping unit. As a result, the adhesive on both side edges of the envelope paper is reliably pressurized at the pressure-bonding portion, and an adhesive force is generated to ensure sealing.

  The sealed letter sealing device 1 according to the present embodiment has an envelope 3 (hereinafter referred to as a foam 3) coated with a pressure-sensitive adhesive 2 along a side edge in the left-right direction as a processing target. In this apparatus, while the foam 3 is conveyed in a direction orthogonal to the left-right direction, the pressure-sensitive adhesives 2 on the side edge portions can face each other and come into contact with each other by folding along the fold line parallel to the left-right direction. To do. Then, by further pressing the side edge portion from above and below while conveying the foam 3, an adhesive force is generated in the pressure-sensitive adhesive 2, and the foam 3 can be adhered to create a sealed letter. In the present application, bonding by pressing is referred to as pressure bonding, and the operation of creating a sealed letter (or also referred to as an envelope) from the form 3 in this manner is referred to as sealing.

(1) 1st Embodiment (FIGS. 1-4)
FIG. 1 shows a sealed letter sealing device 1a of this embodiment.
As shown in FIG. 1, this sealed letter sealing device 1a has a folding enclosing part 4 as a folding part. The contents and the foam 3 are supplied to the fold enclosing unit 4 through different paths. The fold enclosing part 4 forms a sealed letter containing the contents by folding the contents so as to be wrapped in the form 3 and then folding. However, in the present embodiment, the content and the sealing operation in the sealed letter are not essential. For example, if necessary information is printed on the inner surface side of the form 3, the form 3 is folded to form a sealed letter. Only function is enough.

  As shown in FIG. 1 and FIG. 2, the sealed letter sealing device 1a detects the side edge of the folded form 3 in the conveyance path through which the folded form 3 is carried out from the fold enclosing part 4, and detects position data. Has a sensor A as a left / right position sensor. Position data that can be acquired by the sensor A includes position data in the left-right direction of the envelope sheet. As a specific example, as shown in FIG. 2, the dimension L1 from the sensor A to the side edge of the form 3 may be used. Alternatively, the position of the form 3 expressed based on a predetermined reference based on the dimension L1 may be used. In this way, the sensor A acquires the position data in the left-right direction of the envelope paper, and provides it to the control unit 10 described later as information used to determine whether or not the position deviation in the left-right direction has occurred in the envelope paper. As such a sensor A, a reflection sensor or an image sensor can be used.

  As shown in FIGS. 1 and 2, the sealed letter sealing device 1 a has a left and right position adjusting unit 5 that adjusts the position of the folded form 3 in the left and right direction and conveys it downstream of the sensor A with respect to the form 3 conveyance direction. Have. As schematically shown in FIG. 2, the sealed letter sealing device 1a includes a roller-type or belt-type conveying means and an adjusting means (indicated by an arrow a in FIG. 2) for freely moving the conveying means in the left-right direction of the foam 3. ). In FIG. 2, the form 3 that has been sent from the left to the right in the drawing along the conveyance direction is adjusted to the upper side in the drawing by the left and right position adjustment unit 5, and then sent to the later-described crimping unit 6. It has become.

  As shown in FIG.1 and FIG.2, the sealed letter sealing apparatus 1a has the crimping | compression-bonding part 6 which crimps | bonds the side edge part of the folded form 3 in the downstream of the left-right position adjustment part 5 regarding the conveyance direction of the form 3. As shown in FIG. Yes. As shown in FIG. 2, the pressure-bonding portion 6 includes a pressure-bonding roller 7 that is a wheel-shaped drive roller provided with both ends 7 a having a relatively large diameter and a connecting portion 7 b that connects the both ends 7 a with a relatively small diameter. Although not shown, it has a counter roller which is a driven roller that rotates in contact with the pressure roller 7. The intervals and widths of the both end portions 7a of the pressure roller 7 are set so that all or at least a part of the pressure-sensitive adhesive 2 provided on the side edges of the various types of foams 3 can be pressed as will be described later. ing.

  The reason why the wheel-shaped pressure roller 7 is used to sandwich and press the side edge of the foam 3 as in the present embodiment is that the contents may be enclosed in the sealed letter. . If the pressure roller 7 for pressurization is a straight cylindrical roller having a constant outer diameter, any kind of the position of the pressure-sensitive adhesive 2 is different as long as the axial dimension is set long. Even if the foam 3 is slightly displaced in the left-right direction, the entire surface can be always pressed as long as it is within the range of the pressure roller 7, and as a result, the side edge can also be pressure-bonded. it can. However, even if an attempt is made to pressure-bond with a right cylindrical roller when the contents are present, there may be a case where the thickness of the contents becomes an obstacle and a sufficient pressure cannot be applied to the side edge of the foam 3. Therefore, it is necessary to employ a wheel-shaped pressure roller 7 that pressurizes only the side edge portion of the foam 3 and does not apply pressure to the inner portion. In addition, it is advantageous to apply pressure only to the necessary side edge with such a wheel-shaped pressure roller 7 because the driving force of the driving roller can be reduced.

  As shown in FIG. 3, the width of each pressure-sensitive adhesive 2 applied to both side edges of the foam 3 may vary depending on the type of the foam 3, but the pair of pressure-sensitive adhesives 2 in the foam 3 The space in the left-right direction is determined so that the space between the pressure-sensitive adhesives 2 is larger as the width of the foam 3 is larger than the range where pressure can be applied by the both ends 7a, 7a of the pressure roller 7. Therefore, the right and left positioning of the foam 3 is appropriate, and if both side edges are appropriately guided to both ends 7a of the press roller 7 and sandwiched between the opposing rollers, the foam 3 is used regardless of the type of the foam 3. At least a part of both side edges of 3 can be crimped over the entire length of the pattern, and a sealed letter can be created.

  As shown in FIG. 1, the sealed letter sealing device 1 a includes a storage unit 8 that stores sheet data indicating the position of the pressure-sensitive adhesive 2 in the form 3 corresponding to each type of the form 3. For example, as shown in FIG. 3, the sheet data indicating the position of the pressure-sensitive adhesive 2 is a length L2 from the edge of the side edge of the foam 3 to the pressure-sensitive adhesive 2 measured in the left-right direction of the foam 3. , L3 (L3> L2 as an example in FIG. 3).

  As shown in FIG. 1, the sealed letter sealing apparatus 1a has an input unit 9 for inputting the type of form 3 to be used. The input unit 9 may be a panel for manually inputting sealed letter creation information including type 3 type information, or may be an interface unit for inputting the same information from an external information source (not shown) such as a PC.

  As shown in FIG. 1, the sealed letter sealing apparatus 1a has a control unit 10 that controls the entire apparatus. That is, the control unit 10 controls each unit of the apparatus according to the purpose, and also based on the type information of the form 3 input from the input unit 9, the sheet data in the storage unit 8, and the position data from the sensor A. The left and right position of the foam 3 carried out from the fold enclosing unit 4 is adjusted by the left and right position adjusting unit 5 as necessary, and is fed into the crimping unit 6. As a result, even if the foam 3 is conveyed from the fold enclosing portion 4 in the left-right direction, the form 3 is adjusted in the left-right direction and fed to the crimping portion 6 at an appropriate position to ensure sealing. Can be performed.

Next, the operation of the sealed letter sealing device 1a will be described with reference to FIG.
After the user inputs the type of form 3 from the input unit 9 (S1), the user starts sealing by operating a start switch or the like (not shown) in the input unit 9 (S2). The foam 3 and necessary contents are fed into the fold enclosing unit 4 and after necessary alignment is formed into an envelope shape (S3) and conveyed to the subsequent stage. The form 3 sent out from the fold enclosing part 4 is detected by the sensor A in the left-right direction (S4). Based on the type information of the form 3 input from the input unit 9, the sheet data in the storage unit 8, and the position data from the sensor A, the control unit 10 determines the position of the form 3 coming from the folding enclosure 4 in the left-right direction. It is determined whether or not there is a deviation, and if there is a deviation, a correction amount is calculated (S5). When there is no deviation, the calculated correction amount is zero. The control unit 10 controls the left / right position adjustment unit 5 based on the calculated correction amount. As a result, the form 3 moves to the left and right by the correction amount calculated while being conveyed by the left and right position adjustment unit 5 (S6), and is fed into the crimping unit 6, and its both side edges are securely crimped by the crimping roller 7. (S7). The control unit 10 processes the designated number of forms 3 one after another, and determines each time whether or not there is a next envelope creation (S8). Judgment is made (S9) and the apparatus is stopped.

  According to the present embodiment, the side edges of the foam 3 are positioned at both ends of the pressure roller 7 due to an error in setting the foam 3 in the apparatus, a lateral displacement of the foam 3 due to an unexpected movement during conveyance, or the like. It is possible to avoid the inconvenience that it becomes detached from the portion 7a and cannot be crimped or becomes insufficient, and the side edge portion to which the pressure-sensitive adhesive 2 is applied is securely clamped and pressed regardless of the type of the foam 3 It can be crimped to.

  In the sealed seal device 1a as in the present embodiment, as a problem with respect to the position or posture that can occur in the form 3 being conveyed, the positional deviation in the lateral direction (that is, the width direction of the envelope paper) that translates horizontally is simply. Instead, there may be a case where a phenomenon called skewing that occurs with respect to the transport direction occurs. In this embodiment, the sensor A detects the position shift in the left-right direction of the form 3 and corrects the position. However, when the sensor A detects the skew of the form 3, the skew is the left-right described above. The position adjustment unit 5 cannot correct the image, and further, since the skew feeding is detected downstream of the fold enclosing unit 4, there is a possibility that the envelope sheet is folded obliquely. In this case, the envelope sheet itself is folded. Therefore, it is impossible to cope with the problem only by adjusting the left / right position by the left / right position adjusting unit 5. Therefore, in the present embodiment, when the skew is detected by the sensor A, the control unit 10 outputs an alarm by a not-illustrated notifying unit to alert the user, stop the apparatus, or both Shall be performed.

(2) Second embodiment (FIGS. 5 and 6)
FIG. 5 shows a sealed letter sealing device 1b of this embodiment.
As shown in FIG. 5, this sealed letter sealing device 1b is an inline type in which a printing device 20 is integrated. The printing apparatus 20 prints on each sheet supplied from the form feeding unit 21 that supplies the form 3, the content feeding unit 22 that supplies the contents, and the form feeding unit 21 and the contents feeding unit 22. A printing unit 23 for applying Further, the printing apparatus 20 includes a control unit 25 that controls the entire printing apparatus 20 and an input unit 26 that inputs instruction data for printing and sealing operation to the control unit 25. The input unit 26 may be a panel for manually inputting sealed letter creation information including print information and type information of the form 3, or an interface unit to which the same information is input from an external information source (such as a PC) (not shown). Good. The sealed letter sealing device 1b is substantially the same as the sealed letter sealing device 1a of the first embodiment, but there is no dedicated input unit. The control unit 10 of the sealed letter sealing device 1b is connected to the control unit 25 of the printing device 20, so that data input from the input unit 26 of the printing device 20 is also supplied to the control unit 10 of the sealed letter sealing device 1b. It has become. That is, the input unit 26 of the printing device 20 also functions as an input unit of the sealed letter sealing device 1b.

Next, the operation of the inline sealed letter sealing device 1b and the printing device 20 will be described with reference to FIG.
The user inputs information or instructions necessary for printing and sealing including the type of form 3 from the input unit 26 of the printing apparatus 20 (S11), and then operates a start switch (not shown) in the input unit 26. The form feeding unit 21, the content feeding unit 22, and the printing unit 23 are driven to start printing (S12). The control unit 25 of the printing device 20 transmits the type of the form 3 input from the input unit 26 to the control unit 10 of the enclosing sealing device 1b (S13). The printing unit 23 of the printing apparatus 20 prints the contents and sends them to the folding enclosing unit 4 of the enclosing / sealing apparatus 1b (S14). Further, the printing unit 23 of the printing apparatus 20 prints the form 3 and sends it to the folding and enclosing unit 4 of the enclosing and sealing apparatus 1b (S15). The fold enclosing unit 4 of the enclosing / sealing apparatus 1b aligns the form 3 and the contents, and folds the contents in the state where the contents are wrapped in the form 3 to form an envelope (S16). The form 3 sent out from the fold enclosing part 4 is detected by the sensor A in the left-right direction position (left-right position) (S17). The control unit 10 of the enclosing / sealing apparatus 1b starts from the folding enclosing unit 4 based on the type information of the form 3 input from the input unit 26 of the printing apparatus 20, the paper data in the storage unit 8, and the position data from the sensor A. It is determined whether or not the position of the incoming form 3 in the left-right direction is shifted, and if it is shifted, a correction amount is calculated (S18). When there is no deviation, the calculated correction amount is zero. The control unit 10 of the sealing device 1b controls the left / right position adjustment unit 5 based on the calculated correction amount. As a result, the form 3 moves to the left and right by the correction amount calculated while being conveyed by the left and right position adjustment unit 5 (S19), and is sent to the crimping unit 6, and its both side edges are securely crimped by the crimping roller 7. (S20). The control units 10 and 25 process the designated number of forms 3 one after another, determine each time whether or not the next envelope has been created (S21), and when the designated number of sheets is completed (S21, NO) It is determined that the process is finished (S22), and the apparatus is stopped.

  According to the present embodiment, the side edge portion to which the pressure-sensitive adhesive 2 is applied is applied regardless of the type of the foam 3 in a continuous operation from printing to sealing by the same operation as the first embodiment. It can be securely clamped and pressed into a predetermined sealed letter, and the sealed sealing of the printed letter can be performed efficiently and reliably.

  In addition, the response | compatibility when a skew feeding is detected in this embodiment can be performed similarly to 1st Embodiment.

(3) Third embodiment (FIGS. 7 to 10)
FIG. 7 shows a sealed letter sealing device 1c of this embodiment.
As shown in FIG. 7, this sealed letter sealing device 1c is the same as the sealed letter sealing device 1a of the first embodiment shown in FIG. It is. Since the configuration other than the second sensor B is the same as that of the first embodiment, the description thereof is cited.

  This sensor B is the same as the sensor A as the detection element, and detects the form 3 carried into the fold enclosing portion 4 and outputs a skew amount as position data. The control unit 10 determines from the amount of skew output from the sensor B whether or not skew has occurred in the form 3 conveyed to the fold enclosing unit 4. That is, the control unit 10 compares the skew amount reference value stored in advance in the storage unit 8 with the skew amount detected by the sensor B, and determines that the skew is such that a crimping failure occurs. In this case, at least one of the notification operation such as the stop of the apparatus or an alarm is performed without controlling the left / right position adjustment unit 5.

FIG. 8 is a schematic plan view showing a problem that may occur due to the skew of the form 3.
As shown in FIG. 8 (a), when the form 3 is skewed in front of the fold enclosing portion 4, when the skewed form 3 is folded at the fold enclosing portion 4, a regular fold line is formed so that the outer shapes match. Since the foam 3 cannot be folded, the position of the pressure-sensitive adhesive 2 at the side edge does not match and does not overlap correctly. When such a problem occurs, it cannot be corrected. Therefore, in the present embodiment, the operation of stopping the apparatus or performing a notification operation such as an alarm by detecting the skew of the sensor B is performed.

  As shown in FIG. 8 (b), even if the foam 3 is normally folded at the fold enclosing portion 4, if the foam 3 is skewed thereafter, the side edge portion of the foam 3 at the subsequent crimping portion 6 is used. May not be pressurized over the entire length. When such a problem occurs, the left / right position adjustment unit 5 cannot correct it. Even in such a case, in this embodiment, the device is stopped or a notification operation such as an alarm is performed by detecting the skew of the sensor A. It is said.

FIG. 9 is a diagram showing a method for detecting the skew of the form 3.
As shown in FIG. 9A, when a reflection sensor is used for the sensor B, in order to find the edge of the form 3, while the form 3 is being conveyed in the conveyance direction as indicated by an arrow, the sensor The sensor is moved up and down to detect the edge of the form 3 so as to indicate relative movement with respect to the form 3 as indicated by two oblique arrows in the figure. The control unit 10 calculates the skew amount from the difference between the first edge detection position of the sensor and the detection position when the sensor is turned back, and the movement distance of the form 3, and compares this with a reference value determined for each type of form 3. Then, it is determined whether or not the skew is such that crimping failure can occur.

  As shown in FIG. 9B, when an image sensor is used for the sensor B, the sensor moves relatively to the left as indicated by the arrow in the figure with respect to the movement of the form 3 to the right. Since the detected edge position moves, the control unit 10 calculates the skew amount of the form 3 from the amount of change in the edge detection position, and compares it with the reference value determined for each type of form 3. Then, it is determined whether or not the skew is sufficient to cause a crimping failure.

Next, the operation of the sealed letter sealing device 1c will be described with reference to FIG.
After the user inputs the type of the form 3 from the input unit 9 (S31), the user starts sealing by operating a start switch (not shown) in the input unit 9 (S32). Before the form 3 is fed into the fold enclosing part 4, the amount of skew is detected by the sensor B (S33). The control unit 10 is generated in the form 3 entering the folding enclosure 4 based on the reference value of the skew amount based on the type of the form 3 and the skew amount of the form 3 calculated from the position data sent from the sensor B. The degree of possible folding deviation (shown in FIG. 8A) is calculated (S34), and it is determined whether or not a crimping failure occurs in the crimping part 6 in a later step (S35). When it is determined that a crimping error can occur (S35, YES), the occurrence of the crimping error is displayed on the display panel of the input unit 9 and the apparatus is stopped (S37). When it is determined that no crimping error occurs in the crimping section 6 in the subsequent process (S35, NO), the crimping process is performed (S38), and when the designated number of sheets is completed (S39, NO), it is determined that the process is finished. Is stopped (S37).

  In the above description of the operation, the description has been made mainly on the point that the crimping error is detected by the sensor B and the apparatus is stopped by stopping the operation. However, in this case, the operation of the fold enclosing unit 4 is immediately stopped to If the folding of the envelope paper that has been performed is stopped, it is possible to prevent waste that would cause the envelope paper that is inclined obliquely to have an irregular shape that cannot be used. In this case, the skewed envelope paper may simply pass through the folded enclosing unit 4, the left / right position adjusting unit 5 and the crimping unit 6 and be discharged from the end without being processed or adjusted. . If skew is not detected by the sensor B, the folding and sealing unit 4 first folds and encloses the contents, and then handles the same as in the first embodiment. That is, when a lateral displacement in the left and right direction is detected by the sensor A, the lateral position is adjusted by the left and right position adjusting unit 5 as described above, and then sent to the crimping unit 6. Further, when the skew is detected in the form 3 by the sensor A, the crimping error is displayed and the apparatus is stopped without controlling the left / right position adjusting unit 5 as described above.

  According to the present embodiment, in addition to the same effects as the first embodiment, when skew occurs upstream of the fold enclosing unit 4, this is detected and an alarm is output, and the fold enclosing is performed. By immediately stopping the folding operation of the portion 4, it is possible to prevent the foam 3 from being wasted.

(4) Fourth embodiment (FIGS. 11 and 12)
FIG. 11 shows a sealed letter sealing device 1d of this embodiment.
As shown in FIG. 11, this sealed letter sealing device 1d is an inline type in which the printing device 20 is integrated. The printing apparatus 20 is the same as the printing apparatus 20 of the second embodiment, and the sealed letter sealing apparatus 1d is almost the same as the sealed letter sealing apparatus 1c of the third embodiment, but there is no dedicated input unit. The control unit 10 of the sealed letter sealing device 1d is connected to the control unit 25 of the printing apparatus 20, so that data input from the input unit 26 of the printing apparatus 20 is also supplied to the control unit 10 of the sealed letter sealing device 1d. It has become. That is, the input unit 26 of the printing device 20 also functions as an input unit of the sealed letter sealing device 1d.

Next, operations of the inline type sealed letter sealing device 1 and the printing device 20 will be described with reference to FIG.
After the user inputs the type of the form 3 from the input unit 26 of the printing apparatus 20 (S41), the user operates a start switch (not shown) in the input unit 26 to thereby form the form sheet feeding unit 21 and the content sheet feeding unit. 22 and the printing unit 23 are driven to start printing (S42). The control unit 25 of the printing apparatus 20 transmits the type of the form 3 input from the input unit 26 to the control unit 10 of the sealing device 1d (S43). The printing unit 23 of the printing apparatus 20 prints the contents and sends them to the folding enclosing unit 4 of the enclosing / sealing apparatus 1d (S44). Further, the printing unit 23 of the printing apparatus 20 prints the form 3 and sends it to the folding enclosing unit 4 of the enclosing and sealing apparatus 1d (S45). Before the foam 3 is fed into the fold enclosing part 4, the skew amount is detected by the sensor B (S46). Based on the reference value of the skew amount based on the type of the form 3 and the skew amount of the form 3 calculated from the position data sent from the sensor A, the control unit 10 occurs in the form 3 entering the fold enclosing unit 4. The degree of possible folding deviation (shown in FIG. 8A) is calculated (S47), and it is determined whether or not a crimping failure occurs in the crimping part 6 in a later step (S48). If it is determined that a crimping error can occur (S48, YES), the occurrence of the crimping error is displayed on the display panel of the input unit 26 and the devices 20 and 1d are stopped (S49). In that case, the user performs processing such as removing the form 3 or the like in the transport path in the apparatus 20 or 1d (S50), and when the user restarts printing from the input unit 26 (S51). Printing is resumed. When the designated number of sheets has been completed (S52, NO), it is determined that the process has been completed and the apparatus is stopped (S53). Further, when it is determined that no crimping error occurs in the crimping section 6 in the subsequent process (S48, NO), the crimping process is performed (S54), and when the designated number of sheets is completed (S52, NO), it is determined that the process is finished. The apparatus is stopped (S53).

  In the above description of the operation, the description has been made mainly on the point that the crimping error is detected by the sensor B and the apparatus is stopped by stopping the operation. However, in this case, the operation of the fold enclosing unit 4 is immediately stopped to If the folding of the envelope paper that has been performed is stopped, it is possible to prevent waste that would cause the envelope paper that is inclined obliquely to have an irregular shape that cannot be used. In this case, the skewed envelope paper may simply pass through the folded enclosing unit 4, the left / right position adjusting unit 5 and the crimping unit 6 and be discharged from the end without being processed or adjusted. . Further, when the skew is not detected by the sensor B, the folding and sealing unit 4 first folds and encloses the contents, and then handles the same as in the third embodiment. That is, when a lateral displacement in the left and right direction is detected by the sensor A, the lateral position is adjusted by the left and right position adjusting unit 5 as described above, and then sent to the crimping unit 6. Further, when the skew is detected in the form 3 by the sensor A, the crimping error is displayed and the apparatus is stopped without controlling the left / right position adjusting unit 5 as described above.

  As described above, according to the present embodiment, in addition to the above-described effects, when skew occurs upstream of the folding enclosure 4, this is detected and an alarm is output, and the folding operation of the folding enclosure 4 is performed. By immediately stopping the operation, it is possible to prevent the waste of the foam 3 from being generated, and the same effects as in the third embodiment can be obtained.
