However, the present invention is not limited to this, and the cylindrical shape of the barrel portion is a square square. The insertion method of the present invention can also be applied to the case where a label is inserted. In that case, the folding angle of the label forming substrate M may be set to 45 degrees.

  Moreover, in embodiment mentioned above, although the pair L of additional creases f2 is located in the center part of the width direction of the long-angle bottle B, the label L is inserted in the long-angle bottle B, but this When the pair of initial folds f1 formed in advance on the label-forming base material M before the folding is made to correspond to the pair of corners of the long-angle bottle B, the additional crease f2 is not limited. The folding angle of the label-forming substrate M by the folding unit 7 is set so that corresponds to the other pair of corners of the long-angle bottle B. As shown in FIG. After the cylindrical label L opened by the pair of 12 suction gripping arms 12a is shaped into a predetermined opening shape by the opening shaping means 13, it is inserted into the long-angle bottle B as shown in FIG. When the initial crease f1 and the additional crease f2 are long-angle bottles B As substantially coincides with the corners, while rotating the long angle bottle B by a predetermined angle, it may be fitted a label L to the length corner bottle B. In this case, since both the pair of initial folds f1 and the pair of additional folds f2 are engaged with all corners of the long-angle bottle B, the initial fold f1 and the additional folds are not included. When the label L is inserted into the long-angle bottle B, the posture of the label L is naturally corrected so that the label L The long-angle bottle B is securely inserted into a predetermined position of the trunk.

  Further, in the above-described embodiment, each label insertion head 10 includes the label opener 12 that opens the cylindrical label L by the pair of suction gripping arms 12 a and the cylindrical label L that is opened by the label opener 12. Although the rotary type label insertion device 1 provided with the opening shaping means for shaping into a predetermined opening shape by the four opening / closing rods has been described, the present invention is not limited to this, and for example, JP-A-1-139321 The present invention can also be applied to linear label insertion devices such as those disclosed in Japanese Patent Publication No. 1-52172. Therefore, it is not always necessary to provide the opening shaping means, and the label opener is not limited to the pair of suction gripping arms.
