Abstract
Abstract An automatic envelope sealing device wherein envelopes of different sizes can be sealed without adjustment any component of the device. A size of an envelope supplied into the device is detected by a sensor, and in response to a signal from the sensor, a movable stopper is alternatively extended into a plane in which the envelope is to be fed in order to stop a small envelope thereat or retracted therefrom to allow a large sized envelope to be fed until it is stopped by a fixed stopper. A flap of the envelope is then bent positively and paste in a controlled amount is applied to the flap whereafter the envelope is fed reversely until it is discharged outside the device. During the reverse feeding, the flap is pressed to be adhered to the envelope by cooperating rollers which act as feeding means.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
I. An automatic envelope sealing device, comprising a supply table, a receiving table having an upper surface on which an envelope is placed, feeding means for feeding an envelope supplied from said supply table to said receiving table, bending means for bending a flap of the envelope on said receiving table, over an edge of the table, liquid storing means located below said upper surface of said receiving table for storing liquid such as bonding agent or water therein, and liquid applying means mounted for up and down movement between said liquid storing means and the envelope placed on said receiving table for applying liquid to a reverse face of the bent flap of the envelope.
Claim 2
Dependent Claim
47 words
An automatic envelope sealing device as claimed in claim I, wherein said applying means includes an applying member mounted for pivotal motion on a shaft and having at an end thereof a structure which allows only a limited amount of liquid to stick to said applying member.
Claim 3
Dependent Claim
58 words
An automatic envelope sealing device as claimed in claim 2, wherein said structure of said applying member is either in the form of holes formed in said applying member or in the form of a steel wire extending in a lateral or widthwise direction for letting any excess amount of liquid sticking to said applying member drop thereoff.
Claim 4
Dependent Claim
48 words
An automatic envelope sealing device as claimed in any one of the preceding claims wherein the liquid to be stored in said liquid storing means is a bonding agent of the thermally meltable type, the liquid storing means being provided with a heater to heat the contents thereof.
Claim 5
Dependent Claim
78 words
An automatic envelope sealing device as claimed in any one of the preceding claims further comprising a receiving plate mounted at an end of said envelope receiving table and located below a flap of an envelope placed on said envelope receiving table, said receiving plate having an upwardly extending portion, the bending means being located above said receiving plate and being mounted for downward movement into engagement with said receiving plate for bending the flap of the envelope.
Claim 6
Dependent Claim
39 words
An automatic envelope sealing device as claimed in claim 5, wherein said bending means is mounted for pivotal motion on a shaft and has a downwardly bent end and a groove adapted to be engaged by said receiving plate.
Claim 7
Dependent Claim
22 words
An automatic envelope sealing device as claimed in claim 5 or 6 wherein said receiving plate yields resiliently when pressed downwardly vertically.
Claim 8
Dependent Claim
26 words
An automatic envelope sealing device as claimed in any one of claims 5 to 7 wherein said receiving plate is serrated at the free edge thereof.
Claim 9
Dependent Claim
65 words
An automatic envelope sealing device as claimed in any one of the preceding claims further comprising detecting means located adjacent said supply table for detecting a size of an envelope supplied from said supply table, and controlling means operable in response to a signal from said detecting means to position the flap of the envelope thus supplied at a predetermined position on said receiving table.
Claim 10
Dependent Claim
74 words
An automatic envelope sealing device as claimed in claim 9, wherein said controlling means includes a pair of stopper members located in a spaced relationship from each other, the spacing between the stopper members corresponding to a difference between sizes of envelope, the stopper members extending across the receiving table so as to be abutted by the bottom edge of the envelope to stop the envelope at a desired position on the receiving table.
Claim 11
Dependent Claim
88 words
An automatic envelope sealing device as claimed in claim 10, wherein one of said pair of stopper members of said controlling means is formed as a movable stopper which can be moved between a position in which it extends upwardly through the upper surface of said receiving table and another position at or below said upper surface by means of an actuating member while the other of said pair of stopper members is formed as a fixed stopper fixedly mounted at a rear portion of said receiving table.
Claim 12
Dependent Claim
59 words
An automatic envelope sealing device as claimed in any one of the preceding claims, wherein the envelope, after liquid has been applied thereto, is fed reversely toward said supply table so as to pass through said feeding means whereupon the flap of the envelope is closed to the envelope to seal the envelope by means of said feeding means.
Claim 13
Dependent Claim
38 words
An automatic envelope sealing device as claimed in claim 12, wherein said feeding means includes a feed roller connected to be driven by a reversible motor, and a pressure roller mounted for pressure contact with said feed roller.
