Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet enclosing apparatus suitable for enclosing facsimile-received receiving paper in envelope paper.

2. Description of the Related Art A device that encapsulates a document transmitted by facsimile so that it can be handled as a secret document is conventionally known.

For example, Japanese Patent Application Laid-Open No. 63-67072 discloses that by reading an identification pattern displayed at the beginning of a received document, a confidential document can be distinguished from other documents and the transport path can be switched.
The document describes that the envelope is automatically accommodated in a prepared envelope.

On the other hand, Japanese Patent Laying-Open No. 58-142664 discloses an apparatus in which a confidential document is superimposed and pasted as it is so that a communication message can be enclosed so as not to go outside.

Problems to be Solved by the Invention In these conventional enclosing apparatuses, in the former case, paper is stored while being inserted into an envelope, so that a mechanism for opening the mouth of the envelope and inserting the paper becomes complicated, and errors are reduced. There is a drawback that it is easy to occur. On the other hand, if you paste the receiving paper as it is, it will not look good,
Further, the facsimile receiving paper itself has a disadvantage that the received content is easily seen through because the paper is thin. Further, in any of the above cases, since the paper is sealed in the same size, there is a disadvantage that the size is easily increased. In order to solve such a problem, a facsimile receiving sheet has been considered in which the receiving sheet is enclosed by overlapping and folding the envelope sheet. In this case, in order to realize such means, a device for folding the receiving paper and the envelope paper, a device for cutting the continuous envelope paper, and a device for bonding the end portions of the envelope paper by pressure bonding or the like. Equipment is required. According to the present invention, all of these operations are performed at the same time, so that the sheet can be quickly enclosed and the entire apparatus can be compactly assembled.

Means for Solving the Problems To achieve the above object, according to the present invention, there is provided a mechanism for supplying enclosing paper onto a receiving tray, and a mechanism for disposing a continuous envelope paper below the receiving tray with a pair of sending rollers sandwiching the same. A delivery mechanism for delivering the paper onto the guide plate, a paper cutting blade having a blade edge facing the surface of the paper between the delivery roller and the guide plate, and a paper cutting blade arranged parallel to each other below the guide plate. The pair of pressure rollers and the folding blade disposed above the receiving tray are lowered toward a gap formed in the receiving tray and the guide plate, thereby enclosing paper on the receiving tray and on the guide plate. While folding the envelope paper downward below the gap so that the enclosed paper is on the inside. A mechanism for supplying the paper to the pair of pressure rollers and sandwiching the paper between the pressure rollers. The paper drawing speed of the pressure roller is set to be higher than the speed of feeding the envelope paper by the delivery mechanism, and the relative speed Based on this difference, the sheet is shifted to a tension state between the sending roller and the pressure roller, and the sheet is cut by strongly contacting the surface of the sheet with the cutting edge of the cutting blade.

Similarly, a second invention of this application is a mechanism for supplying enclosing paper onto a receiving tray, a mechanism for supplying envelope paper onto a guide plate disposed below the receiving tray, and a mechanism for supplying envelope paper below the guide plate. A pair of end pressing rollers arranged in parallel with each other and a folding blade arranged above the receiving tray are lowered toward a gap formed in the receiving tray and the guide plate, thereby enclosing the receiving tray. While folding the paper and the envelope paper on the guide plate downward from the gap so that the enclosed paper is on the inside, the folded ends are supplied to the pair of end pressure rollers to supply the folded ends. And a mechanism for pinching the paper between the pressure rollers, and pressing the open ends of the folded envelope paper in the direction parallel to the folded end. On both sides of the end pressure roller, the edge pressure roller is provided with an edge pressure roller for adhering the open ends while pressing and pressing both open ends in a direction perpendicular to the folding end of the envelope paper. In addition, at least one of both sides of the ear pressing roller is separate from the end pressing roller, and is the same as the end pressing roller with respect to the feeding direction of the envelope paper. It is characterized by being arranged at a position.

The enclosing paper supplied on the receiving tray and the envelope paper supplied on the guide plate are pushed downward while being folded in two from the gap formed in the tray and the plate by the lowering of the folding blade, The folded end is pulled in by the pressure roller. At the same time, the pull-in of the pressure roller causes the envelope paper to be tensioned at the cutting blade portion, whereby the envelope paper is cut into a predetermined size and the pressure roller adheres each open end of the envelope paper. . At this time, in the second invention of this application, the open end of the envelope paper in the feed direction and the both ends in the direction perpendicular to the open direction are simultaneously pressed.

Embodiments Hereinafter, embodiments of the present invention will be described.

FIG. 2 shows the appearance of the enclosing device (1) of this embodiment. One portion of the upper surface of the box (6) formed in a box shape is raised upward, and the raised portion (4) is raised. The shelf (3) on which the facsimile receiver (2) is placed on the top other than

Switching gate (1
7), a pair of upper and lower sending rollers (18) and (19) provided behind the switching gate (17) and sending only general documents.
And so on. In addition, the delivery belt (13)
A press roller (20) for sandwiching the receiving paper (7) between the belt and the belt (13) is disposed above the middle part of the paper. The belt roller (11) on the side of the intake (5) is supported by a shaft (21), and both ends of the shaft (21) are inserted into a vertical curved fixed guide (22). Along the fixed guide (22), it is possible to turn up and down around the center of the rear roller (12) as a fulcrum. And
The shaft (21) can be fixed at any position by, for example, screws or other means. As the roller (11) and the belt (13) rotate up and down, the lower guide plate (14), the upper guide plate (15), and the pressing roller (2)
0) also rotates up and down.

An identification sensor (23) for identifying whether the received document (7) is a confidential document or a general document is disposed above the end of the upper guide plate (15) on the side of the inlet (5). . As shown in FIG. 5, the identification of the document is a confidential document by reading the identification pattern (25) recorded in the corner of the head of the receiving paper (7) in advance by the sensor (23). Or a general document. For example, when this identification pattern (25) is recorded, it is a secret document, and when it is not recorded, it is a general document. On the other hand, below the lower guide plate (14) opposite to the identification sensor (23), a document take-in sensor (24) for detecting whether or not the received document (7) has entered through the intake (5). ) Is arranged. At the head of the receiving paper (7) in the sending direction, an address record field (26) for recording the address of the recipient is provided. (27) in the figure
Both ends of the slide bar (30) fixed to the lower surface of the lower guide plate (14) at the inlet (5) side are inserted by groove-shaped vertical guides arranged on both sides of the lower guide plate (14). When the end of the belt (13) is rotated up and down as described above, the slide bar (30) moves linearly up and down, and the end of the lower guide plate (14) and the intake port (5). ) In the feed direction is always kept the same.

In the above configuration, the receiving paper (7) discharged from the facsimile receiver (2) enters the intake port (5) and is sent out between the upper and lower guide plates (14) and (15). It is sent out on the belt (13). At a point in time when the feeding belt (13) reaches the middle, the leading end of the receiving paper (7) between the pressing roller (20) and the sending belt (13) is bitten, and the sending belt (13) Is fed out by the rear guide roller (16) and the belt roller (1).
2) It is caught between and is sent forward. At this time,
When the document identified by the identification sensor (23) is a general document, the switching gate (17) is in a horizontal state, and therefore, the receiving paper (7) is kept at this gate (1).
7) The paper is passed between the general paper discharge rollers (18) and (19) at the rear and is discharged to the side. On the other hand, if the document recorded on the receiving paper (7) is a confidential document, the end of the switching gate (17) on the side of the belt (13) rotates upward. Is delivered downward from the point of exiting the delivery belt (13). At this time, the receiving paper (7) of this type is generally widely used in the form of a roll, and the receiving paper (7) discharged from the receiver (2) has a tendency that its leading end bends downward. And is sent smoothly downward. Then, the delivery belt (1
A pair of right and left transport guides (28) for guiding the receiving paper (7) downward is provided at a lower portion between a rear roller (12) for winding the 3) and a guide roller (19) for discharging a general document. )
(29) is provided, and is sent downward through between the guides (28) and (29). These guides (28) (29)
The receiving paper (7) has a curved shape in accordance with the bending thereof, so that the receiving paper (7) can be smoothly sent downward. The receiving paper (7) sent downward in this manner.
Is delivered to the transport and folding mechanism (31) provided on the lower side of the transport guides (28) and (29).

As shown in FIG. 1, the transport and folding mechanism (31) comprises a pair of upper and lower transport belts (32) and (33) disposed obliquely downward from the exit ends of the guide plates (28) and (29).
And a folding guide (35) composed of a pair of upper and lower plates (34) and (34) arranged obliquely upward from the rear end of the transport belts (32) and (33), and an outlet of the lower transport belt (33) Folding guide rollers (36) (42) located close to the edge
(46). A first drive motor (37) is disposed above the rear end of the upper transport belt (33). The first drive motor (37) is driven by a pinion (38) attached to a drive shaft of the drive motor (37). 39), intermediate pinion (40)
Power is transmitted to the roller (42) on the rear end side of the transport belt (32) via the driven gear (41). The transport belt (32) is configured such that the end on the guide plate (28) (29) side is relatively higher than the lower transport belt (33), and the lower transport belt ( 33), the receiving paper (7) sent out between the belts (32) and (33) is at the point where the leading end of the receiving paper (7) comes near the exit side of the belts (32) and (33). Thus, the belt is retracted while being held between the belts (32) and (33). The reason is that the receiving paper (7) discharged from the receiver (2) is not cut by the receiver (2), and both of the transport belts (32) are not cut.
This is because when the receiving paper (7) is pulled in by (33), an unnecessary load is applied to the receiver (2) due to the pulling force. Therefore, these transport belts (32)
The position at which the receiving paper (7) is drawn in between (33) is determined by the length of the receiving paper (7), and according to the length of the receiving paper (7), By changing the inclination of the upper conveyor belt (32), the retraction position can be set. An L-shaped receiving tray (43) is provided below the lower conveyor belt (33).

Next, the operation of the transport and folding mechanism (31) is described in the sixth.
The description will be made in accordance with the figures.

First, the receiving paper (7) sent downward by the guide plates (28) and (29) is transported by the upper and lower conveyor belts (3).
2) Enter between (33). Then, the leading end of the receiving paper (7) is sandwiched and pulled by the belts (32) and (33) at a point near the exit end between the two belts (32) and (33),
As shown in FIG. 6, plate (34) of bending guide (35)
It is sent out into the slit between (34). A stopper (45) is attached to the leading end of the folding guide (35). When the leading end of the receiving paper (7) comes into contact with the stopper (45), the belts (32) and (33) are sent out. As a result, the receiving paper (7) loosens at the entrance end of the folding guide (35) such that it protrudes downward as shown in FIG. This slack is performed along the direction of the curved area of the receiving paper (7) as described above, and thus the operation is a smooth operation. Further, when the belt is fed by the belts (32) and (33), the front end portion bent at the slack portion is formed on the outlet end side where the bending guide roller (36) and the lower transport belt (33) are wound. Between the rollers (46) and these rollers (36)
By (46), it is sent out downward, that is, above the receiving tray (43) (FIGS. 8 and 9). At this time, the receiving paper (7) is folded so that the recording surface side of the document faces down. In this way, a plurality of receiving papers (7) (7) cut by the receiver (2) respectively
Are stacked on the receiving tray (43) (FIG. 10). Then, when the end of the reception is detected by the document take-in sensor (24), the conveyance and folding operation of the reception paper (7) is ended. The end of reception by the document capture sensor (24) is detected by measuring the time from when the last reception paper (7) sent from the receiver (2) has passed through the document capture sensor (24), This can be performed by confirming that the next receiving paper (7) has not entered after a certain period of time. In the delivery mechanism (8), a paper length sensor (47) is provided in front of the guide roller (16) at the rear end of the delivery belt (13). When the position of the leading end of the receiving paper (7) is detected, the presence or absence of paper is determined by the document take-in sensor (24). If the paper is already exhausted at that time, the paper length is longer than the specified length. Is short, and in this case, the operation by the retraction and folding mechanism (31) becomes impossible, so that the identification gate (17) is turned down and the document is discharged in the same manner as a general document. The receiving papers (7), (7),... Stacked on the receiving tray (43) are then sealed by the folding and sealing mechanism (51). The mechanism will be described below.

Envelope paper (52) for enclosing the receiver (7)
As shown in FIG. 11, a known tractor feeder (see FIG. 11) which uses continuous paper having a large number of holes at its both ends is driven by a drive motor (60). 53), the paper is sent out from below the bending guide (35) to the receiving tray (43). At the front of the tractor feeder (53), a pair of upper and lower delivery guide rollers (54) and (54) sandwiching the envelope paper (52) is provided, and at the front of the delivery guide rollers (54) and (54). A cutting buster blade (55) for cutting the envelope paper is arranged. The envelope paper (52) sent out by the guide roller (54) passes below the buster blade (55) and passes through the guide plate (56) disposed below the receiving tray (43) and the receiving tray (43). ) And sent forward. An envelope paper standby sensor (57) is provided in front of the guide plate (56). When the sensor (57) detects that the leading end of the envelope paper (52) has been sent to this position, the sensor is activated. Stop sending the envelope paper (52). The envelope sheet (52) is waiting in a state where it has been sent in advance in this way. At the intermediate portion between the buster blade (55) and the envelope paper standby sensor (57), end pressure rollers (58) and (58) are arranged below the guide plate (56), as shown in FIG. And two ear pressing rollers (59) on both sides of one pressing roller (58)
Is provided. These pressure rollers (58) (59),
Guide roller (54) (54), tractor feeder (53)
Is driven by a second motor (60) provided on its side as shown in FIG. Furthermore, a pressure roller (58)
In response to (59), 1 above the receiving tray (43)
The folding blades (61) are arranged downward.
As shown in FIG. 12, a cam (63) for vertically moving the folding blade (61) is supported above the folding blade (61). The axis of this cam (63) (6
A drive belt (66) is wound between the belt pulley (65) attached to 4) and the roller (42) at the outlet end of the upper retracting belt (32) on the retracting and bending mechanism (31) side. Has been turned. That is, the cam shaft (64) is
6), the one-way clutch (67) for transmitting power only in one direction is provided between the cam shaft (64) and the cam (63). Therefore, when the motor (37) is in the normal rotation state, it is not transmitted to the rotary power cam (63) side, and when the motor (37) rotates in the reverse direction, the cam (63) rotates in that direction. It has become. Also, the camshaft (64)
A slit plate (6) with grooves (68) formed at two locations on its outer periphery

The contact part of the limit switch (70) is in this groove (68) (68)
When one of the motors (37) falls, the limit switch (70) is operated to stop the reverse rotation operation of the motor (37). That is, in this embodiment, since the grooves (68) and (68) are formed at positions opposite to each other on the circumference of the slit plate (69), the slit plate (69), that is, the cam (63) is moved halfway around. Each time the reverse rotation operation of the motor (37) is stopped.

Next, the operation of the folding enclosing mechanism (51) will be described. As described above, when the document capture sensor (24) detects that the output of the received document has been completed, the 13th
As shown, the last receiving paper (7) is in the receiving tray (43)

FIG. 19 is a flowchart showing a flow of control by the control device. In the figure, steps ~
Shows a flow for determining whether the document is a confidential document. The step is an operation for judging whether or not the sheet length is sufficient, and discharging the sheet not having a sufficient length (for example, a sheet having a length shorter than the length of the folding guide (34)). Step-is a work to determine whether the finished sending one document, quit the uptake of the sheet time T ₁ of the at the next sheet is taken equal to the time a predetermined t ₁ This indicates that transmission of one document has ended. That is, the time interval between documents is longer than the time interval for a series of documents.
The T ₁ longer than the interval time series document (usually about 13 seconds) by setting, it is to determine the end of a document. Moreover, steps-is finished sending one document, those which gave the latency t ₂ for timing to perform encapsulation. The following steps are specific flows for performing enclosing, cutting of envelope paper, and the like. In these steps, the timer T _3, since it is intended to keep only stopped a predetermined time t ₃ at its bottom dead center position the blade (61), and a detailed description thereof will be omitted.

Effect of the Invention As described above, according to the present invention, the folding of the enclosing paper and the envelope paper, the cutting of the envelope paper, and the pressure bonding are performed almost simultaneously, so that a series of these operations is performed very quickly. At the same time, as compared with the case where these steps are performed step by step, the apparatus itself is also compacted, and the envelope is automatically cut by the pulling force of the pressure roller, so that the cutting blade is moved or the envelope paper is moved. No special equipment is needed to hit the cutting blade,
There is an effect that the device itself is simplified. Of course, since the cutting is performed directly by the cutting blade, the cutting can be surely performed at that position. In addition, the pressing of the envelope paper is performed not only more quickly but also at the same time, since the ends in the feed direction and the direction perpendicular thereto are pressed together, the rollers for pressing them are arranged in one place. Therefore, the effect that the device can be made more compact can be obtained. In addition, since the sheet is fed in the discharge direction while being bonded in this manner, the time until the discharge can be shortened accordingly, and there is no need to separately provide a discharge roller and a bonding roller. In addition, as shown in the embodiment, the pressure roller for bonding the ends needs to be retracted in accordance with the thickness of a certain portion of the contents, but since the roller for bonding the ears is a separate member. The ear can be securely pressed without being affected by the retreating operation of the end pressing roller.
