Reference numeral 76 denotes a stop mechanism which is configured to stop the rotation of the drive motor 11 and stop the conveyance of the adherend W when the adherend W having a predetermined thickness or more is detected. is there.

Since this embodiment has the above-mentioned structure, the power switch 59 of the control operation unit 58 is turned on, and in the case of continuous sticking, the sticking start margin L ₁ and the sticking end margin L ₂ are set as shown in FIG. In the case of intermittent paste, see Fig. 15.
As described above, in addition, the sticking length L ₃ and the tape length L ₄ are set, and the envelope as the adherend W is placed on the placing plate 3 and its side edge is set as the abutting portion 45 a of the position setting plate 45. When the sensor 66 detects the leading edge of the envelope when it is inserted laterally in the right direction in FIG. 1 while contacting, the drive motor 18 is driven by this, the conveyor belt 17 is driven by the rotation of the drive shaft 11, and the envelope is conveyed by the conveyor belt. It is conveyed by the circulation traveling of 17.

At this time, the pressing roller 42 of the pressing mechanism 39 presses the envelope from above, and the envelope is placed on the mounting plate 3 and the pressing roller 4.
It is sandwiched by 2 and conveyed reliably.

Next, when the sensor 67 detects the front end of the envelope in the conveying direction, the counting circuit in the control unit 65 starts counting the pulse generated from the rotary encoder, and the pulse is sent at the set operation timing based on the counted number. Clutch 25 and cutter clutch 5
4 will operate.

In this case, from the roll R of the holding portion 5 to the guide portion 36.
The front end T ₁ of the adhesive tape T pulled out through the roller faces the peripheral surface of the pressing roller 42 that has passed through the feeding roll 32 and the sandwiching roll 34 at the beginning, and first, the feeding clutch 25
The feed shaft 25a is rotated by the operation of, and the adhesive tape T is fed while being sandwiched by the rotation of the feed roll 24 and the sandwiching rolls 27 and 28, and the adhesive tape T is fed obliquely to the upper surface of the envelope as the adherend W. The adhesive tape T is adhered to the envelope by its adhesive surface with the margin L ₁ at the start of sticking, sandwiched between the conveyor belt 17 and the pressing roller 42, and stuck, and then cut based on the above operation timing. Part 4
Cutter clutch 54 of 6 operates and cutter shaft 53
Starts rotating, and the crankshaft 56 is moved by the cutter shaft 53.
Rotates at a high speed clockwise and rotates 360 degrees, the cutter clutch 54 is disengaged, and the cutter shaft 53 is stopped.
Due to this rotation, the mounting plates 50a and 50b swing about the fulcrum shaft 51 and the blade body 47b slides with respect to the blade body 47a, and the pair of blade bodies 47a and 47b move in the feeding and feeding direction of the adhesive tape T. The adhesive tape T is to be cut while moving to, and the cut adhesive tape T is sandwiched and fed by the feeding roll 32 and the sandwiching roll 34, and the adhesive tape T is enveloped with the sticking end margin L ₂ left. The adhesive tape T that has been adhered to and cut off after cutting is sent by the feed roll 24 and is sent in the middle in cooperation with the payout roll 32, and the tip T ₁ of the adhesive tape T is the circumference of the original pressing roller 42. The feed clutch 25 is disengaged at a position facing the surface, the adhesive tape T stops and stands by at that position, and the trailing edge of the envelope in the transport direction is delivered from between the pressing roller 42 and the transport belt 17. The attachment of the adhesive tape T is completed, and the same operation is repeated thereafter.

Therefore, the adherend W is automatically conveyed by sending the adherend W to the conveying unit 7, and the adhesive tape T is fed by the supplying unit 20 from the holding unit 5 onto the adherend W being conveyed. The adhesive tape T is fed out and fed, the cutting unit 46 cuts the adhesive tape T into a predetermined length, and the adhesive tape T can be automatically adhered to the adherend W, which can be used for office work such as sealing of an envelope. Higher efficiency can be achieved.

At this time, in particular, the cutting section 46 moves the pair of blade bodies 47a, 47b capable of cutting and sliding with each other and the pair of blade bodies 47a, 47b in the feeding and feeding direction of the adhesive tape T. In this case, the cutting mechanism 48 is configured to rotate and cut, and in this case, 180 degrees in FIG. 10 after 90 degrees rotation in FIG. 9 after rotating clockwise from the cutting operation start position in FIG. Position close to rotation, in this case cutting range θ
The cutting is performed between the blades and the blades 47a and 47b are immediately separated from each other, so that the adhesive tape T is smoothly fed and a good cutting operation can be obtained.

Further, in this case, since the crank mechanism is adopted as the cutting mechanism 48, the structure can be simplified and the cutting sliding operation of the blade bodies 47a, 47b can be performed at high speed and reliably.

Further, since the pair of blades 47a and 47b are arranged in a direction substantially orthogonal to the feeding direction of the adhesive tape T during cutting and sliding, the blade 47b is substantially orthogonal to the adhesive tape T. Contact with each other in a state, disconnect instantly and separate,
The adhesive tape T can be cut well.

Although the present invention is applied to an adhesive tape sticking device for envelopes, it can be used not only for envelopes but also for plate-like bodies such as calendars and posters, and not only single-sided tapes but also double-sided tapes and the like. Can also be used for .

[0027]

As described above, according to the present invention, the adherend is automatically conveyed by sending the adherend to the conveying section, and the adhesive tape is fed out from the holding section by the feeding belt of the supplying section and conveyed. It is fed out and fed onto the adherend, the cutting part cuts the adhesive tape to a predetermined length, and the adhesive tape can be automatically adhered to the adherend, and the office work of sticking the adhesive tape such as envelope sealing In particular, the cutting part has a pair of blades capable of cutting and sliding with respect to each other and a pair of blades capable of cutting and sliding while moving in the feeding and feeding direction of the adhesive tape. Since it is composed of a mechanism, the adhesive tape can be smoothly fed and a good cutting operation can be obtained.

Further, by adopting the crank mechanism as the cutting mechanism, the structure can be simplified and the cutting / sliding operation of the blade can be performed at high speed and reliably.

Further, since the pair of blades are arranged in a direction substantially orthogonal to the feeding direction of the adhesive tape during cutting and sliding, the blades contact the adhesive tape in a substantially orthogonal state and are momentarily contacted. The adhesive tape can be satisfactorily cut by cutting the adhesive tape to separate it.

As described above, the intended purpose can be sufficiently achieved.
