DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic envelope sealing device.

[0002]

2. Description of the Related Art As is well known, direct mail, home delivery service (home delivery service), and the like are increasingly used as means for transmitting information using printed matter as a medium. Under such circumstances, the envelope is filled with printed matter as information,
Further, the operation of sealing this envelope is increasing. In view of this, various automatic envelope sealing devices have recently been proposed (for example, Japanese Patent Application Laid-Open No. 7-25197).

[0003] In these automatic envelope sealing devices, an envelope flap fed into the case main body by an envelope feeding mechanism from an insertion / ejection opening is bent and bent, and the flap is attached to the envelope main body using an adhesive tape or glue. It has a sealing mechanism. The envelope sealed in this way is discharged from the insertion / ejection opening by reversing the envelope feeding mechanism. Insertion / ejection of an envelope for sealing is performed via a guide attached to an insertion / ejection opening.

[0004]

As described above, the insertion and removal of the envelope is performed through the guide attached to the insertion / ejection port, and the envelope inserted into the case body is sealed therein and inserted again. Since it returns to the guide via the outlet, the next envelope cannot be supplied unless the returned envelope is removed from the guide, and this time is a waiting time, and there is a problem that the sealing speed is limited.

[0005]

In order to solve the above-mentioned problems, an automatic envelope sealing apparatus according to the present invention is provided with an insertion guide and a discharge guide in two upper and lower stages on a guide, and is inserted into the case body from the insertion guide. When the envelope is ejected after being automatically sealed, the waiting time can be reduced by allowing the next envelope to be supplied while the envelope is being ejected by allowing the envelope to be ejected on the ejection guide.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to an automatic envelope sealing device having a built-in automatic closing mechanism for automatically closing an envelope. And a guide for discharging the envelope are provided in two upper and lower stages. The envelope is inserted into the case via the insertion guide, and the envelope sealed in the case is discharged through the discharge guide.

[0007]

FIG. 1 shows an embodiment of the present invention. Slot 1 provided on one side of case body 1
The envelope guide 2 is attached to a. In the case body 1,
An automatic sealing mechanism for automatically sealing the envelope with an adhesive tape, glue or the like is incorporated (not shown), and this automatic sealing mechanism can be started and stopped by a switch 3.

The insertion / ejection opening 1a is for inserting and ejecting an envelope. The insertion / ejection opening 1a is formed horizontally so that the bottom can be inserted into the bottom surface of the end of the envelope guide 2. The upper side is rounded so that the tip of the envelope can be easily inserted. The front end of the above-described envelope guide 2 is fitted into the insertion / ejection opening 1a, and is set horizontally so that the envelope can be inserted into and ejected from the inside of the case.

The envelope guide 2 supports both sides of the envelope insertion guide 2b and the ejection guide 2c by the side plate portions 2a on both sides, and when the fitting is inserted into the insertion / ejection opening 1a, the front end is stably attached to the case body. It is formed so that it can be mounted. The envelope insertion guide 2b and the discharge guide 2c are provided in two upper and lower stages with the former positioned upward. The insertion guide 2b has an inclined surface that slightly lowers the tip end side, and inserts the envelope into the insertion / ejection opening 1a.
It is easy to move toward. Also, the envelope discharge guide 2c is formed so as to be parallel to the bottom 2d of the side plate portion and to have a front end portion slightly protruding from the front end of the side plate portion, so that the envelope to be discharged is guided on the discharge guide. . In addition,
An auxiliary guide (not shown) that expands and contracts according to the width of the envelope to be sealed is provided on the upper surface of the envelope insertion guide, so that the envelope can always be inserted straight according to the change in the width of the envelope. It is.

In the above configuration, when closing the envelope, the switch 3 is turned on after adjusting the width of the auxiliary guide. Next, after the printed material is placed on the insertion guide 2b with the side having the flap of the envelope filled in front, and inserted into the case main body 1, a feed roller (not shown) provided in the case main body 1 is provided. The envelope is pulled in. In the case body 1, the flap is bent at a right angle by the automatic sealing mechanism, and then the half of the width of the adhesive surface of the adhesive tape is pressed against the outside of the flap and affixed. The flap and the adhesive surface of the tape are pressed against the main body of the envelope to seal.

The envelope sealed in the case body 1 is inserted into the insertion / ejection port 1a by reversing the above-mentioned feed roller.
From the case body. When the envelope is ejected, the envelope is ejected so that the bottom side of the envelope comes out at the end (the left end in FIG. 1) of the ejection guide 2c. Envelope is guide 2 for discharge
When it is on the uppermost position c, the insertion guide 2b is empty, so that the next envelope can be inserted. As a result, the waiting time for discharging is shortened, and the efficiency of the sealing operation is improved. In this embodiment, the automatic sealing mechanism is sealed with an adhesive tape, but may be sealed with glue. The shape of the insertion / ejection port and other configurations are not limited to those shown in the drawings.

[0012]

According to the present invention, by providing an envelope guide in which an insertion guide and an ejection guide for an envelope are provided in upper and lower two stages, a new insertion guide is provided during ejection of an envelope sealed in the case body. Since a simple envelope can be inserted, the efficiency of the sealing operation is improved.
