Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
The label attachment positioning jig 1 is used to attach a shrink label to a beverage bottle before shrinking the shrink label (cylindrical label) attached to the body of the beverage bottle by heat in the beverage bottle manufacturing process. It is used in the attaching process (label attaching process).

First, the label attachment process will be explained.
In the label attaching process, as shown in FIG. 2, the label attaching positioning jig 1 is guided in three vertical movements by a mandrel, presses the upper end 5a of the cylindrical label 5 (indicated by the two-dot chain line in the figure), and presses the cylindrical label 5 (indicated by the two-dot chain line in the figure). The cylindrical label 5 is attached to the bottle body 7a by inserting the label 5 into the bottle 7 from above.
Although the bottle 7 is a resin bottle in the embodiment, it may also be a bottle. Further, in the present embodiment, the bottle 7 is exemplified as a square bottle having a substantially rectangular shape in plan view.

A total of four mandrels 3 are provided at equal intervals in the circumferential direction, and gradually descend from above to below the bottle 7.
As shown in FIG. 2(a), a label mounting positioning jig 1 is inserted through the mandrel 3, and the label mounting positioning jig 1 is supported by a support member 9. Separately from the mandrel 3, a support member 9 is used to move it up or down.
The mandrel 3 holds the cylindrical label 5 by holding the cylindrical label 5 at its lower side so as to spread from the inside.
The label mounting positioning jig 1 descends from above the tubular label 5 and comes into contact with the upper end 5a of the tubular label 5, with the mandrel 3 holding the tubular label 5.

As shown in FIG. 2(b), when the mandrel 3 further descends together with the support member 9 and the lower end of the mandrel 3 reaches the upper part 7b of the bottle 7 (near the cap position), the lower end 5b of the cylindrical label 5 It is located so as to cover the upper part 7b of the bottle 7.
From this position, as the support member 9 descends, the label mounting positioning jig 1 descends.

As the label attachment positioning jig 1 descends, the cylindrical label 5 descends from above to below the bottle 7 so as to cover the bottle 7, and as shown in FIG. 2(c), the cylindrical label 5 is attached to the bottle body. A cylindrical label 5 is attached to the bottle 7, covering the entire area 7a.
Thereafter, as shown in FIG. 2(d), the mandrel 3 and the label mounting positioning jig 1 are raised.

Next, the configuration of the label mounting positioning jig 1 will be explained with reference to FIG. 1.
The label mounting positioning jig 1 includes a substrate 13 in which a rectangular bottle upper insertion space 11 is formed in the center, and a fixing portion 9a of the support member 9 is provided on the upper surface of the substrate 13.
The bottle upper insertion space 11 is a hole into which the upper part 7b of the bottle 7 is inserted, as shown in FIG. 2(c).
Furthermore, mandrel insertion spaces 15 into which each mandrel 3 (see FIG. 2) is inserted are provided in the substrate 13, corresponding to the positions of the mandrels 3. In the first embodiment, the mandrel insertion space 15 is a space that is continuous with the bottle upper insertion space 11, and has a generally rectangular shape in plan view as a whole, and the four corner portions are the mandrel insertion spaces 15.

An inner positioning section 17 and an outer positioning section 19 are provided on the lower surface of the substrate 13.
As shown in FIG. 1(b), the inner positioning portion 17 protrudes from the lower surface of the substrate 13, and the tip 17a has a hemispherical curved surface.
As shown in FIG. 2(a), when the label mounting positioning jig 1 descends and comes into contact with the upper end 5a of the cylindrical label 5, the inner positioning portion 17 is formed as shown in FIG. Then, it enters the inner peripheral side (inside) of the cylindrical label 5 and maintains the cylindrical label 5 in an open state.
A total of two inner positioning parts 17 are provided at positions facing each other across the bottle upper insertion space 11.

The outer positioning part 19 has a substantially V-shape with the bottle upper insertion space 11 side opened in a plan view from below, and a part of the upper end 5a of the cylindrical label 5 is placed inside the V-shape. I'm letting them in.
In this embodiment, the cylindrical label 5 has a fold line 5c formed at the time of label manufacture at an opposing position, and the fold line 5c is located in the outer positioning part 19.
Here, a good mounting state and a bad mounting state of the cylindrical label 5 will be explained.
FIG. 3(a) shows a state in which the cylindrical label is properly attached. FIG. 3(b) shows a defective state in which the cylindrical label 5 has slipped through the bottle upper insertion space 11, and the cylindrical label 5 cannot be attached halfway. FIG. 3(c) shows a defective state in which the letters ABC are shifted laterally.

Next, the effects of the label mounting positioning jig 1 according to the first embodiment will be explained.
According to the label mounting positioning jig 1, when inserting the cylindrical label 5 into the bottle 7 from above while holding down the upper end 5a of the cylindrical label 5, as shown in FIG. ), by inserting the inner positioning portion 17 inside the cylindrical label 5, the cylindrical label 5 can be held in an open state, so that the cylindrical label 5 can be smoothly inserted into the bottle 7.
Thereby, improper mounting of the cylindrical label 5 can be prevented.
Moreover, since the inner positioning part 17 has a curved tip 17a, it can be placed inside the cylindrical label 5 in a sliding manner without being caught on the upper end of the cylindrical label 5.

Since the bottle upper insertion space 11 is formed in the base plate 13 of the label attachment positioning jig 1, the cylindrical label 5 can be lowered into the bottle upper insertion space 11 to the upper part 7b of the bottle 7. Easy to fit into.
By providing the inner positioning part 17 across the bottle upper insertion space 11, the upper end 5a of the cylindrical label 5 comes into contact with the substrate 13, as shown in FIG. 1(a), so that the cylindrical label 5 It is possible to prevent the bottle from slipping out of the upper insertion space 11.
Furthermore, when the inner positioning portion 17 contacts the cylindrical label 5, the friction can prevent the cylindrical label 5 from shifting laterally.

Further, since the outer positioning portion 19 comes into contact with the outer circumferential surface of the cylindrical label 5, it is possible to further prevent attachment failure due to lateral displacement of the cylindrical label 5.
Since the outer positioning part 19 has a V-shaped opening facing the bottle upper insertion space 11 side, a part of the cylindrical label 5 enters inside the V-shaped opening to form an angle, making positioning easy. .
In particular, in this embodiment, since the cylindrical label 5 has a fold 5c formed during its manufacture, positioning is facilitated by positioning this fold 5c with the outer positioning section 19.

Further, by providing the outer positioning portions 19 at positions opposite to each other across the bottle upper insertion space 11, in cooperation with the inner positioning portions 17, it is possible to prevent the cylindrical label 5 from shifting or coming off.
The outer positioning part 19 and the inner positioning part 17 are provided facing each other and form diagonal corners of a quadrangle at four locations in total, so that they can be held approximately equally at four locations in the circumferential direction, so that the cylinder can be held in a well-balanced manner. Since the shaped label 5 is held, it is possible to further prevent incorrect attachment.

In this embodiment, as the bottle 7 to which the cylindrical label 5 is attached, a square bottle is used as an example where the cylindrical label easily hangs on the shoulder of the bottle. I was able to install it. That is, according to the present embodiment, when the bottle 7 is a square bottle, it is possible to effectively prevent improper attachment.
Furthermore, in this embodiment, experiments were conducted on various thicknesses of the cylindrical label 5, and no attachment failure due to slip-through occurred in any of the cases of 45 μm, 40 μm, and 35 μm. Furthermore, no installation failures due to lateral slippage occurred.
In addition, in the experiment, a biaxially stretched polystyrene resin film (OPS) of any thickness was used.
That is, a shrink label with a thickness of 45 μm or less is particularly weak and easily causes attachment failure due to slipping through, but even the cylindrical label 5 having such a thickness could be attached to the bottle body 7a satisfactorily. Similar results were also obtained with HOPS (Hybrid-OPSid-OPS/hybrid styrene shrink film) of 45 μm, 40 μm, and 35 μm.
