The transport guide 12 holds the container 1 and the second
String holding members 60 provided on both sides of the transport guide 12
While the both ends of the string 11 are held by a and 60b, the string 11 is integrally transported to the string tying station E as it is.

In the tying station E, the first tying gripper 84a and the second tying gripper 86a are connected to the first tying gripper 84a and the second tying gripper 86a, respectively.
Hold 1 Thereafter, a bow is formed by the steps shown in FIGS. 15 (a) to 15 (c) and FIGS. 16 (d) and 16 (e). First, the second string knot gripper 86a is moved so that the string 11 is located on the near side and below both rods 88 and 90 (the second string knot gripper 86 in FIG. 15A).
a)). Next, rod cylinders 88a, 9
0a, the rods 88, 90 are advanced, and by operating the pin cylinders 92a, 94a, the tips (heads 92b, 94b and thin rods 92c, 94c) of the pins 92, 94 are moved to the respective rods 88. , 90 (position shown in FIG. 15A).

Next, the first string knotting gripper 84a is moved, and the string 11 held by the gripper 84a is positioned above the first rod 88 at the tip of the second rod 90, and is moved by the pin cylinder 94a. The pin 11 of the second rod 90 is retracted to grasp the string 11 (see FIG. 15B). Further, the second tying gripper 86a is moved,
The string 11 held by the gripper 86a is
The rod 90 is wound up around the string 11 held at the tip of the rod 90 and is pulled out upward (see FIG. 15C).
, And the pin 92 is retracted to grasp the string 11 (see FIG. 16D).

Thereafter, the grippers 84a, 86a are opened at the same time as the rods 88, 90 are retracted, and the portion held by the string 11 is pulled out to form a bow (FIG. 16 (e)). reference). At this time, appropriate tension is applied by the interference cylinders 88b and 90b, and at the same time, the pins 92 and 94 of both rods 88 and 90 are applied.
Again, the string 11 is separated from the pins 92 and 94 by its own elasticity. In this way, a clean bow can be automatically made by a simple process.
In the embodiment, as shown in FIG. 15C, the string 11 held by the second gripper 86a is used.
Is wrapped around the string 11 held by the second rod 90, but if the second rod 90 is further protruded and wrapped around both rods 88 and 90,
First lacing gripper 84a and second lacing gripper 86a
Can move at the same time, so that the operation time can be shortened. The present invention is not limited to the structure shown in the above embodiment, and it goes without saying that the shape, structure, and the like of each part can be appropriately modified or changed.

As described above, according to the apparatus for feeding a piece of paper into a container according to the present invention, a substantially pyramid-shaped lower mold having a plurality of convex portions and a plurality of concave portions, and a concave-convex portion of the lower mold are provided. An upper mold having a concave and convex portion, and a folding habit forming member having a diameter slightly larger than the head of the container and having a notch formed at a position corresponding to the convex portion of the lower mold. After forming the unevenness on the paper piece by sandwiching it between the lower mold and the lower mold, the paper piece is placed on the head of the container and pressed on the container by the folding habit member, so that it is supplied to the container by a simple mechanism. As you can make a good crease on the piece of paper, and you can firmly add a fold along the outer shape of the container,
Even in the subsequent tying step, it is possible to supply a good-looking paper piece without wrinkling. Furthermore, since the process of temporarily folding a paper piece and supplying it to the head of the container and then forming a folding habit can be automated and incorporated into a production line, the processing speed can be increased and the production efficiency can be improved. .
