Then, the cutting blade 62 fixed to the cutting blade holding member 61 projects downward from the sliding contact surface 22 of the sticking unit body 2 and cuts the packaging tape A guided by the guide plate 41 (see FIG. 8). ).

At this time, a biasing force for rotating the guide plate 41 toward the rear is applied, but as described above, the guide plate 41 is interlocked with the pressing board 51, Since the pressing substrate 51 is rotated and displaced rearward while the pressing roll 52 is in sliding contact with the box C, and is housed in the sticking unit main body 2,
The guide plate 41 holds the state of being housed in the pasting unit body 2. Moreover, since the wrapping tape attachment member 41d is arranged on the guide plate 41 and the wrapping tape A is supported in a state along the rear surface of the guide plate 41, the wrapping tape guided by the guide plate 41 Since the tape A is located above the sliding contact surface 22 of the sticking unit body 2, and the packaging tape A is tensioned by the tension roll 72, the cutting blade is The wrapping tape A can be cut smoothly and surely only by projecting 62 below the sliding contact surface 22 of the sticking unit body 2.

Further, when the box C is conveyed forward, the pressing board 51 is always urged so that its lower end portion is rotated and displaced in the forward direction. Is rotated and displaced in the transport direction of the box body while pressing the pressing roll 52 from the upper surface of the box body C to the upper end portion of the rear surface thereof, and the cut end portion of the packaging tape is The box body can be securely attached to the upper end of the rear surface of the box body C, and the box body can be I-shaped and sealed (see FIG. 9).

Next, an explanation will be given of the usage procedure for sealing the box body in an L shape. First, similarly to the case of the I-shaped sticking and sealing, the front end of the packaging tape A is attached to the upper end of the front surface of the box body, and the guide plates 41 allow the left and right outer flaps C1, C1 of the box body C to be attached. Guide the wrapping tape A over the space (see FIGS. 6 and 10).

Then, in the L-shaped sealing, the packaging tape A guided on the box C is cut along the upper surface of the box C. In the I-shaped sealing, the cylinder rod 81a of the pneumatic cylinder 81 is always urged in the direction of contracting rearward, and the guide plate 41 and the pressing substrate 51 are urged in the direction of separating from each other. In the L-shaped sticking seal, when the packaging tape A is cut in the middle of the upper surface of the box C, the cylinder rod 81a of the pneumatic cylinder 81 is extended in the opposite direction, that is, toward the front. The guide plate 41 and the pressing substrate 51 are rotated and urged in the directions in which they are in contact with each other.

Then, as shown in FIG. 11, the lower edge of the guide plate 41 is displaced above the cutting blade 62 of the cutting blade holding member 61. In this state, the wrapping tape A that is guided from the guide plate 41 and extends from the leading edge is the guide plate 41.
It is in a state where no tension is applied because it is bent downward due to the upward displacement.

On the other hand, the packaging tape A is constructed so that it is unwound and guided to the guide plate 41 side unless the tension of a certain amount or more is applied by the tension roll 72 on the base end side thereof.

When the box C is conveyed further forward, the packaging tape A is attached and fixed to the upper surface of the box C at the tip side of the box C. It moves forward together with the box C. By displacing the front end side of the packaging tape A in this manner, tension is gradually applied to the packaging tape A guided from the guide plate 41 and extended from the leading edge, and the packaging tape A gradually becomes in a tension state. At the same time, it is displaced upward, and finally, it is about to be displaced on a plane connecting the leading edge of the guide plate 41 which is rotated and displaced upward and the sticking end of the packaging tape A, but as described above. , The guide plate 41,
Since the lower edge thereof is displaced to a state in which it is positioned above the cutting blade 62 of the cutting blade holding member 61, the packaging tape A is displaced from the leading edge of the displaced guide plate 41 and the packaging tape A.
The cutting blade 62 before being displaced on the plane connecting the sticking end of
Be disconnected by.

Note that the wrapping tape A is cut by the cutting blade 62.
When cutting, the packaging tape A has a high cutting strength, and the packaging tape A is not smoothly cut by the cutting blade 62.
Even when the cutting blade 62 is about to be pushed upward by the packaging tape A, the cutting blade holding member 61
Prevents the further upward movement by abutting and receiving the rear end surface of the plate-shaped body 611 to the rear stopper piece 61b, and keeps the cutting blade 62 in an immovable state to ensure The packaging tape A can be cut by the cutting blade 62.

After the packaging tape A is cut by the cutting blade 62 as described above, the box C is further transported to the front side, and the brush disposed on the rear side of the packaging tape sticking unit 1 is arranged. The cut end of the packaging tape A is pressed and stuck onto the box C by the tip of 11a (see FIG. 11).

Finally, a usage procedure for dot-sealing the box body will be described. First, the guide plate 41 and the pressing substrate 51 are preliminarily extended and extended in the cylinder rod 81a of the pneumatic cylinder 81 to rotate and displace in a direction in which they are in contact with each other, and are housed in the sticking unit body 2. Keep it. The leading end of the packaging tape A is guided to the rear surface of the guide plate 41 in the same manner as above. On this occasion,
The wrapping tape A guided to the rear surface of the guide plate 41 is always guided by the wrapping tape attachment member 41d of the guide plate 41.
Since it is configured to hold the state along the rear surface of the guiding tape 41, an unexpected situation such that the leading end portion of the packaging tape A is detached from the rear surface of the guide plate 41 and becomes drooping does not occur (see FIG. 12). ).

While keeping this state, the box C is conveyed forward by the conveyor B2, and the box C is supplied to the packaging tape sticking unit 1. Then, when the box body is conveyed forward by a certain distance, the guide plate 41 is pivoted and displaced rearward by contracting the cylinder rod 81a of the pneumatic cylinder 81 rearward, and its leading edge portion, that is, , The packaging tape pressing portion 41c is pressed against the abutting portions of the left and right outer side flaps C1, C1 of the box C, and the tip of the packaging tape A attached to the rear surface of the guide plate 41 is pressed onto the box C. , And adhere (see FIG. 13).

While maintaining this state, the left and right outer flaps C1 and C1 of the box C are made in the same manner as the above I-shaped sealing.
After guiding and sticking the wrapping tape A for a certain length on the space, the wrapping tape A is displaced upward by displacing the guiding plate 41 in the same manner as the L-shaped sticking and sealing. Disconnect by. After that, the cutting end of the packaging tape A is further pressed by the brush 11a, which is the second packaging tape pressing mechanism 11 arranged on the rear side of the packaging tape sticking unit 1, to stick it on the box C. Then, the dot sticking sealing is completed (see FIG. 14).
