Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for creating an envelope from a notification document in which necessary information is printed on continuous paper using an output device such as a computer.

Conventionally, the method used to create envelopes for billing notices, receipt notices, and payment notices was to print the necessary information on continuous paper and then fold the continuous paper in succession to create envelopes. The method is to apply heat-sensitive adhesive in advance to a predetermined part of a flat continuous form before information is printed, that is, the part that will be the sealing position when folded into an envelope, and then to print this continuous form after information is printed. A sealed letter was created by folding it into a sealed letter and passing it through hot plates arranged above and below in this state, or by passing it through a hot pressure roller or the like and bonding it under heat.

However, when printing on continuous paper coated with heat-sensitive adhesive or the like in advance using an electrostatic printer, which is an output device such as a computer,
Particularly in printers that use heat to fix toner prints, the heat-sensitive adhesive softens during printing, and this adhesive adheres to the rollers inside the printer, causing a number of problems such as jamming and printing defects. Continuous paper coated with heat-sensitive adhesive or the like can no longer be used in electrostatic printers because of the problems it causes.

Further, as described above, in order to create a sealed letter by folding a continuous form to which sealing adhesive has been applied in advance, the form of notification paper is limited, and various notification tasks are also limited.

Therefore, in the present invention, the notification sheet that is passed through a printer or the like to print the necessary information is separated from the notification sheet that is constructed without any sealing adhesive and the notification sheet that is configured without any sealing adhesive. Envelope paper, that is, envelope paper that is used without passing through an electrostatic printer, is coated with a heat-sensitive adhesive that does not adhere under normal conditions, and is easy to handle in a flat state until the envelope is created. Using this, you can print without any problems even when printing with an electrostatic printer, and the notification paper on which information is printed can be reliably matched with the envelope paper.
Furthermore, the present invention provides a method for creating a sealed letter in which a flat envelope sheet can be accurately and easily clamped at an intermediate position and a sealed letter can be created very simply.

Next, this invention will be described in detail based on drawings relating to embodiments of the invention.

Next, the present invention will be explained using the above-mentioned notification paper 1, envelope paper 11, and sealed letter creation device 30.

First, the notification sheet 1, on which the addressee and corresponding necessary information are printed in each address field 7 of each unit notification sheet 2, is inserted into the address strip 8 at the fold perforation 6 provided in the continuous direction of the notification sheet 1. While folding it into a Z-shape with the paper facing upward, the paper is continuously folded and pulled into the folding device 32, and the pinholes 4 in the marginal portions 5 provided on both sides of the notification paper 1 are set in the transport tractor 33 of the notification paper transport unit 31. do. On the other hand, the envelope paper 11 has marginal parts 15 provided on both sides of the envelope paper 11.
The pinhole 14 is passed through the transport tractor 52 of the envelope paper transport section 51 to transfer the notification paper 1 to the notification paper transport section 31 and the envelope paper 11 to the envelope paper transport section 51.
After each is set, the envelope creation process begins.

In the notification paper transfer section 31, the notification paper 1 is
The folding device 32 is continuously folded into a Z-shape by the driving force of the transporting tractor 33 and transported, and the margin slitter 34 provided at the rear of the transporting tractor 33 cuts off the marginal part. Further, in the process of passing between the infeed roller 35, blade 36, and high speed roller 37 of the cutting device 38, the notification sheet 1 is subjected to tension and tension due to the speed difference between the infeed roller 35 and the high speed roller 37. Each address is cut by a fixed blade 36 that assists in tearing using tension, and then transferred to a transfer/change device 42 by a transfer delivery 39 and sent to a sheet receiving plate 40 of the transfer/change device 42 . Then, this unit notification sheet 1 is pushed out by changing its direction toward the take-in belt 62 by a feed claw 41 that reciprocates at right angles to the direction of transfer of the transfer delivery 39 with its sides folded.

On the other hand, in the envelope paper transport section 51, the envelope paper 11 is driven at a timing determined by a sensing signal from a timing sensor 64 provided near the paper receiving plate 40. The marginal portion 15 is cut off by a margin slitter 53 provided at the rear of the transport tractor 52, and then passes through an infeed roller 54, which is a cutting device 57, a blade 55, and high speed rollers 56, 56. As a result, the unit envelope paper 12 is cut from the perforation 13 into a single piece, and sent to the folding and transporting section 61 by the push-out roller 63 and the pull-in roller 66.

In the folding transfer section 61, the unit envelope paper 12 is moved by a push roller 63 and a pull roller 66.
The upper side is pushed up by the stopper 65.
When the unit envelope sheet 12 hits the fold line 17 in the middle, it bends toward the pull-in rollers 66 and 66', and at the same time, the leading edge of the unit notification sheet 2 sent from the take-in belt 62 bends to the fold line 17. At the end, this unit notification form 2 is the unit envelope form 1.
The retracting rollers 66, 66 are in a state where the address column 7 of the unit notification sheet 2 is exposed through the window 19 of the unit envelope sheet 12, and the unit notification sheet 2 is sandwiched inside the adhesive 18 applied to the adhesive portion 16 of the unit envelope sheet 12. ' and sent to the sealing section 71.

In the sealing section 71, the folded unit envelope sheet 12 is held in the folded state by a transfer belt 73, and is transferred to pass through the sealing sections on both sides between the heating plates 74 that face each other vertically. , heat is applied to the heat-sensitive adhesive 18 that has been applied to the glue margin 16 in advance, which is the bonding condition for the adhesive 18, and the adhesive 18 is passed between the pressure rollers 75 and both sides of the unit envelope paper 12 in the transport direction are applied. After bonding, the thermocompression bonding work of the previous thermocompression bonding portion 72 is completed. Next, in the transfer change device 82, when the unit envelope paper 12 is fed from the pressure roller 72 to the paper receiving plate 80, the feeding claw 81, which reciprocates orthogonally to the transfer direction of the previous stage thermocompression bonding section 72, moves the unit envelope paper 12 to the paper receiving plate 80. The side edges of 12 are pushed out and sent to the subsequent thermocompression bonding section 76.
Then, the unit envelope sheets 12 sent to this thermocompression bonding section 76 are transferred while being sandwiched by a transfer belt 77 in the same way as in the previous stage thermocompression bonding section 72, and the glue margin 16 on one side of the unsealed section is removed. The sealed letter is passed between the upper and lower opposing thermal plates 78 and then passed through the pressure roller 79 at the rear stage of the transfer belt 77 to complete the sealing operation, and sent to the letter receiver 83 to create the sealed letter according to the present invention. Here, since the thickness of the notification paper stacked inside the envelope paper differs, when passing it between the pressure rollers, the process of passing the first pressure roller and the passing direction are changed by 90 degrees, and the second pressure roller The first pressure roller applies pressure to the enclosed notification sheet and the overlapping envelope sheet by sandwiching the notification sheet, thereby smoothing the entire surface of the envelope sheet. At the same time, it is possible to press the glue margin of the envelope paper perpendicular to the passing direction, and with the entire paper in close contact, the second pressure roller presses the glue margin in the passing direction (the first pressure roller presses and tightly contacts the paper). If the adhesive that does not normally adhere is a pressure-sensitive adhesive, for example, the first and second If a thermal plate that applies heat is provided before and after the second pressure roller, heat will be applied while the vertical and horizontal glue margins of the envelope paper are in close contact with each other, or after the heat is applied. Since it is crimped, the glue margin is securely crimped.

As explained above, in this invention, since the notification paper and the envelope paper are provided separately, the adhesive applied to the sealing position of the envelope paper may be made of a heat-sensitive adhesive. Furthermore, even if a printer uses an electrostatic printer to print information and create a sealed letter, only the notification paper needs to pass through the electrostatic printer, and the addressee and the information corresponding to the addressee. are all printed on the notification paper,
Envelope sheets coated with heat-sensitive adhesive do not pass through the electrostatic printer, and problems such as jamming and printing defects do not occur in the electrostatic printer.

In addition, depending on the amount of information, the notification sheet can be left as is, or it can be folded as many times as desired while being transported by attaching a folding device or a cutting and stacking device to the notification sheet transport section, or it can be folded and folded as many times as desired. It can be enclosed in various forms, making it extremely versatile.

Furthermore, when matching notification sheets and envelope sheets, even if the envelope sheets are in various forms such as intact, folded, or cut and stacked, they are placed on the paper tray during transportation, and the Since alignment is performed at the center of the paper, the paper can be transferred to the envelope paper side with certainty in the same direction, and the envelope paper is transferred at a timing related to the transfer of the notification paper. Between the start and completion of the two-fold process, the notification paper is ejected toward the fold line side of the envelope paper and folded in half, with the window side of the envelope paper and the address field of the notification paper corresponding to each other. Since the envelope paper is created by inserting the notification paper into the envelope paper and transferring it in the polymerized state in the adhesive application direction, applying adhesive conditions to the adhesive in the adhesive area sequentially, it is possible to prevent the attachment of the notification paper and the envelope paper. There are no mistakes in alignment or sealing,
It can be held accurately and easily, and envelopes can be created extremely easily.
