Simultaneously with the joining, the air cylinder 417 is extended and the tape pressing pad 403 presses the tape 20 portion located on the tape receiving member 401.

The action of vacuum on the suction pad 407 is that the suction pad 407 attaches the tip of the tape 20 to the ear portion 90.
When the tape 20 is joined to the ear 903, the air cylinder 44 is released.
9, the suction pad 407 is retracted upward. Further, when the joining member 413 descends, the air cylinder 455 expands, the tape 20 is cut by the cutter 451, and the cutter 45 cuts the tape 20.
1 is immediately raised, and when the joining member 413 starts to rise, the rodless cylinder 445 returns. Then, when the next container 9 is confirmed at the ear press station S3, the air cylinder 449 is extended and the tip of the tape 20 held by the tape pressing pad 403 is pressure-contacted and sucked by the vacuum, and the tape pressing pad 403 is attached.
And the suction pad 407 is moved to the upper side of the other side of the container 9 with the tip of the tape 20 adsorbed, and the same operation as above is repeated.

The container 9 to which the tape 20 is attached in this way
Are transferred to the edge folding station S5, the ears 903 are folded and joined to the left and right surfaces 15, and subsequently, the resin layer is cooled by the cooling stations S6 and S7, and the ears 90
3 is joined to the left and right surfaces 15 and is discharged onto the roller conveyor 7 in the state shown in FIG.

According to this embodiment, with the pair of ears 903 projecting outward from the left and right surfaces 15 formed on the upper surface 901, the guide member 307 extends between the pair of ears 903.
The tape 20 is placed from above, and the tape 20 portion located on each ear portion 903 is attached to each ear portion 903.
Since the guide member 307 is removed after the attaching, and the ear portion 903 is folded and joined to the left and right surfaces 15, the tape 20 is pulled by the ear portion 903 when the ear portion 903 is folded on the left and right surfaces 15. Therefore, the guide member 307
By setting the thickness and height of the tape appropriately, or the tape 20
When attaching the portion of the tape to the ear 201, the amount of slack of the tape 20 can be adjusted by changing the height of the ear 903 with respect to the upper surface 901, and the tape 20 can be provided with a desired amount of slack.
Can extend over the upper surface 901. If the guide member 307 is omitted, the tape 20 can be extended on the upper surface 901 of the container 9 in a stretched state.

Further, the seal margin 19 is a portion where the front and rear surfaces 13 and the left and right surfaces 15 are joined and has strength.
In the embodiment, since the tape 20 is arranged on the sealing margin 19, it is advantageous when the tape 20 is used as a handle.

Further, when the tape 20 is fed out or joined to the container 9, the tape pressing pad 403 is moved up and down, the suction pad 407 is moved up and down, and left and right as in the embodiment, and the joining member 413 is used.
Since it was done by combining the vertical movement of
The tape 20 can be attached to the container 9 efficiently and reliably in a narrow space.

The tape sticking device 4 according to the present invention can be applied to the upper surface of the container 9 without the ear portion 903.
In this case, the ear receiving member 411 is omitted and the tape 2
At the time of joining 0, the joining member 413 is brought into direct contact with the upper surface of the container 9.

[0039]

As is apparent from the above description, according to the tape sticking method and device of the present invention, the tape is stuck to the side portion of the container, and the tape is simply extended on the upper surface of the container. In addition, since the amount of slack of the tape extending on the upper surface can be adjusted, the tape can be attached to the upper part of the container with a good appearance, especially when the container becomes large and the weight of the filling object becomes large. Since the tape can be easily handled and the tape is prevented from being excessively slackened, it is advantageous that the tape is not caught even when a large number of large containers are handled at one time.
