It is composed of a section 70. A large number of contents P, which are contents, are stacked on the mounting plate 2 of the paper feeding unit 1. The letter P is sent out from the paper feed unit 1 by the paper feed roller 3. The letter P is guided by the guide and supplied to the paper folding section 10. In this paper folding section 10, bottomed folding members 11 and 12 are arranged with their openings facing upward, and three rollers 13, 14 and 15 are arranged near the openings. The letter P sequentially enters the folding members 11 and 12, and is sandwiched between the rollers 13 and 14 and between the rollers 13 and 15 to be folded in three.

In the envelope hopper 20, an envelope H is loaded on a mounting plate 21 with its flap F facing upward. The envelope H is sent out from the hopper 20 by the feeding roller 22, guided on the guide 23, reversed in the traveling direction by the reversing roller 24, and then supplied to the content insertion section 30.

A pair of feed rollers 31, 32 and a pair of feed rollers 33, 34 are arranged in the insertion portion 30 so as to face each other in the horizontal direction. A belt 35 is stretched between the rollers 31 and 33, and the envelope H moves from the roller 31 to the roller 33 together with the belt 35 due to the movement of the belt 35 by the rotational driving of the rollers 31 and 32. A stopper 46 and an idler 45 are arranged between the roller 31 and the roller 33. A cam 41, which is rotationally driven by a motor 39, is arranged below the belt 35. The cam 41 and the motor 39 are coaxially connected. One end of the lever 43 is rotatably supported by the rotary shaft 44, and the lever 43 can swing about the rotary shaft 44. A cam follower 42 is provided at the other end of the lever 43, and when the cam follower 42 rolls on the peripheral surface of the cam 41, the lever 43 swings. A stopper support portion 47 connected to a stopper 46 is fixed to the lever 43, and an idler 45 is attached to the other end portion of the support portion 47. The idler 45 is arranged between the forward path (upper side) and the return path (lower side) of the belt, and the lever 43 rotates clockwise to lift the belt 35 as shown by a broken line. On the contrary, when the lever 43 rotates counterclockwise, the stopper 46 projects upward of the belt 35, and locks the front end portion of the envelope moving on the belt to stop the envelope.

A cam follower 50 rolls on the cam 41. The cam follower 50 is attached to one end of an L-shaped right-angled arm 49 rotatably supported by a rotation shaft 51. ing. An arm 54 is connected to the other end of the right angle arm 49 via an engaging portion 52, and a claw member 53 for opening the flap F of the envelope is provided at the end of the arm 54. As a result, when the cam 41 rotates, the right angle arm 49 rotates, the arm 54 moves in the horizontal direction, and the claw member 53 moves in the horizontal direction. A tension spring 48 is interposed between the lever 43 and the end of the arm 49, and the tension spring 48 holds the cam followers 42 and 50 in a state of rolling on the cam 41.

An L-shaped right-angled arm 63 is rotatably supported by a rotation shaft 62 near the rollers 33 and 34 at the outlet of the insertion section 30. The wetting member 61 is connected to one end of the arm 63, and the drive shaft of the plunger 64 is connected to the other end of the arm 63. Then, when the plunger 64 is driven and its drive shaft retracts, the arm 63 rotates in the clockwise direction, so that the moistening member 61 projects upward.

On the downstream side of the moisturizing member 61, a bottomed pocket 65 is arranged with its opening facing upward, and rollers 66, 67, 68 are provided in the vicinity of this opening. The roller 68 and the roller 67 are arranged to roll, and the roller 66 and the roller 67 are arranged to roll.

A stacking unit 70 for collecting the sealed envelopes H is arranged near the rollers 66, 67. The stacking unit 70 is mainly composed of a sheet discharge tray 71 which is a bottom portion, a guide 76 which is disposed in front of the envelope H in the entrance direction and serves as a front wall portion which locks the front end portion of the envelope H, and also the envelope. A rear wall portion 75 that locks the rear end portion of H is provided, and the paper discharge tray 71 is inclined so that the rear wall portion 75 side becomes lower. The gap between the lower end portion of the rear wall portion 83 and the rear end portion of the paper discharge tray 71 is an entrance 83 through which the envelope H enters.

The envelope H is placed on the paper discharge plate 71, and the pressing plate 72 is provided on the stacked envelopes H. A locking member 79 is provided at an end portion of the pressing plate 72 on the rear wall portion 75 side. The locking member 79 is attached to a slit 74 formed in the rear wall portion 75 and extending in the vertical direction. Engaged. As a result, the pressing plate 72 can move in the vertical direction, and presses the envelopes H stacked on the paper discharge plate 71 by its own weight. A handle 78 is attached to the upper surface of the pressing plate 72.

A guide 77, which is a front wall portion of the stacking unit, is rotatable around a support shaft 89 in front of the stacking unit 70, and is normally urged by a spring 76 in a standing state. On the other hand, by tilting the guide 77 forward (toward the front) against the biasing force of the spring 76, the envelopes collected in the stacking portion 70 can be taken out.

On the sheet discharge plate 71 of the stacking unit 70, a sheet discharge tray 80 is slid with respect to the sheet discharge plate 71 via a rail 81 fixed to the sheet discharge plate 71 and a pin 82 engaged in the rail 81. It is movably connected. The tiltable guide 77 described above is attached to the front end portion of the paper output tray 80. Further, when the paper output tray 80 is pulled out to the maximum, the paper output tray 80 rotates downward about the pin 82.

Next, the operation of the enclosing and sealing machine configured as described above will be described. First, a large number of letters P are placed on the paper feeding unit 1, and empty envelopes H are loaded on the envelope hopper 20. After that, the paper feed roller 22 is rotated to take out one envelope H from the envelope hopper 20 and send it to the guide 23. At this time, the flap F of the envelope H is opened by the front wall portion of the envelope hopper 20. Then, the direction of travel of this envelope is reversed by the reversing roller 24, and then it is sandwiched between the rollers 31 and 32 of the insertion section 30. The envelope H is sent out onto the belt 35 by the rollers 31 and 32 with the flap F open, and moves toward the rollers 33 and 34 as the belt 35 moves. At this time, the cam 41 rotates counterclockwise to the position where the cam follower 42 rolls on the large diameter portion of the cam 41 as shown in FIG. For this reason, the cam follower 42 is lifted by the cam 41, and the stopper 46 projects onto the belt 35 moving in the outward path. The front end of the envelope H is locked by the stopper 46, and the envelope H stops.

Next, the cam 41 further rotates, and the cam follower 50 relatively moves to the large diameter portion of the cam 41. Then, the right angle arm 49 rotates clockwise, the arm 54 moves forward (in the moving direction of the envelope), and the claw member 53 advances. Then, the claw member 53 enters into the opening of the envelope H where the flap F is opened and pushes the opening wide. On the other hand, one sheet of letter P sent from the paper feed unit 1 by the paper feed roller 3 enters the folding member 11 of the paper folding unit 10, and its front end abuts the bottom of the folding member. Then, the central portion ⅓ of the letter P bends toward the rollers 13 and 14, and is sandwiched between the rollers 13 and 14 in a folded state. Next, the letter P enters the folding member 12 with this polygonal line as the leading end, and the letter P sent out by the rollers 13 and 14 even after the leading end contacts the bottom of the folding member 12 is the central part thereof. It is sandwiched between the rollers 13 and 15 at the 2/3 part and folded at this part. In this way, the letter P folded in three is stopped by the stopper 46 and enters the envelope H through the opening of the envelope H opened by the claw member 53.

Thereafter, when the cam 41 further rotates, the cam follower 42 relatively moves to the small diameter portion of the cam 41, the lever 43 rotates clockwise, and the stopper 46 retracts downward. As a result, the envelope H moves forward again with the letter inserted inside and the flap F open. In this case, the idler 45 is raised by the rotation of the lever 43 and lifts the belt 35. As a result, the intermediate portion of the belt 35 bulges upward and contacts the envelope to increase the conveying force thereof, and the envelope is reliably conveyed toward the rollers 33 and 34.

After that, the envelope H is sent out from the insertion portion 30 to the sealing portion 60 by the rollers 33 and 34. Adhesive is previously applied to the lower surface of the flap F of the envelope H, and when the adhesive portion of the flap F passes through the moisturizing member 61, the plunger 64 is driven and the piston retreats. The right-angled arm 63 rotates in the clockwise direction and the moisturizing member 61 moves up slightly to apply moisture to the glue portion of the flap F of the envelope H. On the other hand, the front end of the envelope H enters the pocket 65 and contacts the bottom of the pocket 65. Therefore, the flap F, which is the rear portion on the belt 35, is sandwiched between the rolls 67 and 68 and closed, and the opening portion of the envelope H is sealed. The envelope H in which the contents are thus enclosed is then sandwiched between the rolls 67 and 68, then sandwiched between the rolls 66 and 67, and enters the stacking unit 70 from the flap F side.

A pressing plate 72 is placed on the discharge plate 71 at the bottom of the stacking unit 70, and the envelope H after sealing is placed between the discharge table 71 and the pressing plate 72 via the inlet 83. And is placed on the paper output table 71. The envelopes H after being sealed in this manner are supplied to the lowermost layer of the envelopes H already stacked in the stacking unit 70 by the feeding force of the rolls 66 and 67, and the discharge tray 71. Sent in between. As a result, the envelope H fed by the rolls 66, 67 is lifted against the gravity of the pressing plate 72 and the already stacked envelopes, and is inserted into the lowermost layer. The holding plate 72 rises along the slit 74 as the stacking height of the envelopes H increases. In this way, after the enclosing and sealing work is completed, the guide 77 is tilted forward, so that the envelope H on the sheet discharge plate 71 can be easily taken out without being lifted upward. The flap F, which has been moistened by the moisturizing member 61, is superposed on the envelope and then sandwiched between the rolls 67 and 68 and between the rolls 66 and 67, whereby the adhesive action is promoted and at the stacking portion 70. When the envelope is pressed by the weight of the pressing plate 72, the flap F is further pressed and the adhesive action is promoted.

When the size of the envelope changes, the position of the folding guide 77 can be adjusted by sliding the paper discharge tray 80 of the stacking unit 70. Further, when the paper ejection tray 80 is pulled out to the maximum extent, the paper ejection tray 80 is tilted forward together with the folding guide 77 so that all the envelopes on the paper ejection plate 71 can be easily taken out.

If the folding guide 77 is tilted before the enclosing and sealing work, the enclosed envelopes can be sequentially ejected onto an external ejection stand.

[Effect of the device]

 As described above, according to the present invention, while the empty envelope is moved in the direction perpendicular to the fold line of the flap without changing the path, the empty envelope is sequentially sealed by the inserting means, the moisture applying means and the sealing means. Since the work is configured to be performed, the movement mechanism of the envelope and the contents can be simplified and the movement route thereof can be shortened. In addition, this envelope after sealing was introduced into the stacking unit from the lower part and laid down on the bottom of the stacking unit, and the front wall was rotatably provided with respect to the bottom, so it was loaded on the bottom. You can easily remove the sealed envelope with one hand.
