Is connected to the power supply circuit 102 via the control circuit 104 of the sticker label sticking apparatus 10.

Next, the operating conditions of the sticker label sticking device 10 and the heating device 110 of this embodiment will be described. First, as shown in FIGS. 2 and 3, the cylindrical container A is laid down sideways, and its bottom is brought into contact with the positioning member 88,
The seal A is placed on the drive roller 70 and the support roller 74 so that the seam between the body A1 and the lid A2 to which the seal label L is to be attached is on the pressing roller 60. This time,
Center axis of the cylindrical container A (dotted line C shown in FIG. 13)
The directional position is determined by the positioning member 88.
The position of the cylindrical container A in the direction of the central axis is the body A1 and the lid A2.
The seam between and is adjusted on the pressing roller 60 so as to be located at the center portion in the width direction of the seal label L fed from the peeling plate 34. Further, the position of the support roller 76 is adjusted by the adjusting screw 86 according to the diameter of the cylindrical container A. By adjusting the position of the support roller 76, the height of the cylindrical container A from the substrate 12 can be adjusted.
By adjusting the height of the cylindrical container A from the substrate 12, the degree of contact between the cylindrical container A and the pressing roller 60 can be adjusted so that a pressing force suitable for sticking the seal label L can be obtained. it can.

Next, a switch (not shown) connected to the control circuit 104 to start the rotation of the cylindrical container A.
Can be inserted. Then, the drive motor 92 rotates and, via the gears 94 and 96 and the shaft 72, the drive roller 7
0 is rotated. Then, the cylindrical container A is rotated clockwise in FIG. When the shaft 72 rotates, the pulleys 64 and 68 and the transmission belt 66 rotate the pressing roller 60 via the shaft 62. at the same time,
The transfer roller 38 is rotated via the gears 96 and 98, the clutch 42 and the shaft 40. Also, shaft 4
The take-up roller 50 is rotated via 0, the pulleys 54 and 58, the transmission belt 56, and the shaft 52. The gear ratios of the gears 94, 96 and 98 are formed so that the sticker label continuous body R can be transferred and the sticker label L can be fed at a speed substantially the same as the rotating speed of the cylindrical container A. Further, the ratio of the pulleys 64 and 68 is formed so that the pressing roller 60 can rotate in the reverse direction with respect to the cylindrical container A at substantially the same speed as the rotating speed of the cylindrical container A. Further, the ratio of the pulleys 54 and 58 is formed so that the release sheet S can be wound at a speed substantially the same as the transfer speed of the continuous seal label body R.

When the drive roller 70 rotates, the cylindrical container A is rotated while keeping its central axis at a predetermined position. At the same time, when the transfer roller 38 is rotated, the sticker label continuous body R is sequentially transferred. Then, the seal label L is peeled off by the peeling plate 34, and is fed toward the joint between the body A1 and the lid A2 of the cylindrical container A. The fed sticker label L is sequentially pressed by the pressing roller 60 so as to cover the joint between the body A1 and the lid A2 of the cylindrical container A.

After one sticker label L is completely peeled from the sticker label continuum R and fed out, the black print layer L4 of the next sticker label L is applied to the sticker label detecting sensor 3
6 is detected. Then, the control circuit 104 sends a signal to the clutch 42, and the clutch 42 disconnects the shaft 40 from the rotation of the gears 94 and 98, and the rotation of the shaft 40 is stopped. Therefore, the drive roller 3
The rotation of the roll 8 and the winding roller 50 is stopped, and the transfer of the sticker label continuous body R is stopped.

The cylindrical container A is continuously driven by the drive roller 70.
Is rotated by. Along with the rotation, the seal label L is attached around the joint between the body A1 and the lid A2 of the cylindrical container A by the pressing roller 60 so as to wind around.

Further, as shown in FIGS. 2 and 3, the heating device 110 is set at a predetermined position in advance.
In this embodiment, the cylindrical container A is rotated at least once and the sticker label L is attached over its entire length, and then heating by the heating device 110 is started. That is, heating of the sticker label L is started by transmitting power to the heating device 110 after a predetermined time has elapsed since the next sticker label L was detected by the sticker label detection sensor 36. This timing is controlled by the control circuit 104.
Measured by

By being heated by the heating device 110, the sticker label S is heat-shrinked in the longitudinal direction thereof and comes into close contact with the joint between the body A1 and the lid A2 of the cylindrical container A. This heating is performed uniformly while rotating the cylindrical container A. Then, the cylindrical container A is subjected to a predetermined number of times.
Is rotated, the seal label L is sufficiently heat-shrunk, and heating and rotation are stopped when the shrink wrapping is completed. This timing is also measured by the control circuit 104.

Further, the attachment state of the sticker label L will be described with reference to FIGS. 9 to 12. The lid A2 of the cylindrical container A used in this embodiment is a so-called cap type, as shown in FIG. Then, the sticker label L is attached along the joint between the body A1 and the lid A2 so as to wind around. In this case, as shown in FIG. 9, the substantially central portion in the width direction of the sticker label L is attached so as to be along the one end edge of the body A1 of the substantially cylindrical container A. Therefore, the one end in the width direction of the sticker label L is attached to the ends of the body A1 and the lid A2, and the other end in the width direction is arranged so as to project to the outside.

After the sticker label L is stuck around,
As shown in FIG. 10, the heating device 110 blows hot air to start heating the sticker label L. Then, as shown in FIG. 11, the seal label L starts to shrink from the heated portion. In this case, the seal label L is heat-shrinked by being folded in the direction of the lid A2 at the substantially central portion in the width direction. In this embodiment, since the seal label L is formed by using the PVC film uniaxially stretched in its longitudinal direction, it is thermally shrunk in its longitudinal direction by heating,
It comes into close contact with the joint of the cylindrical container A. After sufficient heat shrinkage, by stopping heating and rotation, the sticker label L is attached to the body A1 and the lid A2 of the cylindrical container A.
It solidifies by cooling while keeping the shape that fits the shape near the seam. In this way, as shown in FIG. 12, the shrink wrap with the seal label L is completed.

As described above, the sticker label sticking apparatus 1
According to 0, anyone can easily shrink-wrap. With the heat-shrinkable seal label L, the lid A2 and the body A1 of the cylindrical container A can be fixed so as not to be easily displaced, and the cylindrical container A can be substantially sealed. Further, the sticker label sticking device 10 is small, does not occupy a mounting space, and is easy to carry. Furthermore, since a heat-shrinkable seal label is applied and then heat-shrinked, a preforming step such as the conventional shrink cap is unnecessary. Therefore, the present invention is suitable for shrink packaging of small lots, and can easily cope with small lot production of various kinds.
