<D> Label Supply Means (FIG. 1) The label supply means comprises a rotary table 22, a cutting device 23, a transfer drum 24 and a heating means 25. The turntable 22 is a table on which the roll R on which the label L is continuously wound is set. The cutting device 23 is a device that individually cuts the tape-shaped labels L supplied to the transfer drum 22. The transfer drum 24 is a drum body for supplying the cut labels L to the sticking drum 21 and is attached to the table 11 via a support shaft 241 provided at the center. On the peripheral surface in the middle of the support shaft 241, the aforementioned support shaft 2 is provided.
As in the case of 11, a flange portion 242 is formed and locked on the upper surface of the table 11, and a lower portion of the support shaft 241 penetrates the table 11, and a driving force transmitting gear 243 is attached to the peripheral surface. Further, the transfer drum 24 has a structure in which the label L is sucked and transferred on its peripheral surface. The suction of the label L may be performed by opening a plurality of holes on the peripheral surface of the transfer drum 24 and generating a negative pressure in the holes. The heating device 24 is a device for heating the label L, and causes the adhesive attached to the back surface of the label L to have adhesiveness by the heating.
The means for supplying the label L to the sticking drum 21 is not limited to the turntable 22, the cutting device 23, the transfer drum 24, and the heating device 24, but one label L stored in the label holder. It may be of the type that supplies each.

<E> Driving Device (FIG. 1) The driving device 3 is a device that applies a driving force to rotating members such as the sticking drum 21, the transfer drum 24, and the cutting device 23 while synchronizing each other. The driving device 3 includes, for example, a motor 31, a gear box 32, a plurality of gears, and a plurality of rotating shafts, and each of these members has a considerable weight and is therefore all installed on the base 1. Motor 3
Reference numeral 1 denotes a driving source of the driving device 3, which is mounted on the base 1. Like the motor 31, the gearbox 32
Are mounted on the base 1, and the driving force of the motor 31 is introduced to supply a rotating force to a rotating shaft extending in each direction.

The transmission of the driving force from the motor 31 to the rotating member is performed via a gear box 32, a plurality of gears, or a rotating shaft. That is, the driving force of the motor 31 is transmitted to the gear 33 via the gear box 32, a plurality of gears or a rotating shaft, and the sticking drum 21, the transfer drum 24, It is transmitted to a rotating member installed on the table 11 such as the device 23.

[0013]

Next, the operation of the labeling machine will be described.

As shown in FIG. 2, the tape-shaped labels L sent from the turntable 22 are individually cut by a cutting device 23 and supplied to a transfer drum 24. And transfer drum 2
The label L is transferred from the label 4 to the sticking drum 21, and is sequentially attached to the adherend 8 being transferred on the transfer path 9. That is, the label L is wound around the adherend 8 while the adherend 8 transported at predetermined intervals by the star 93 of the transport means 9 is brought into contact with the peripheral surface of the sticking drum 21.

On the other hand, when the adherend 8a having a different outer shape is transported along the transport path 9 in place of the adherend 8, it may be necessary to change the label L sticking position. In that case, the adherend 8a
The table 11 is moved up and down in accordance with the position where the sheet is to be attached. For example, as shown in FIG. 5, when the position of attachment to the adherend 8a is higher than that of the adherend 8, each of the rotating shafts 12 is rotated in a predetermined direction, and the table 11 is moved upward. Let it. In this case, as the table 11 moves, the support shaft 211 and the gear 213 of the sticking drum 21 and the support shaft 243 of the transfer drum 24 and other gears also move upward. However, even if the support shaft 211 moves upward, its lower end is engaged with the gear 33 of the driving device 3, and the rotating member (from the driving device 3 side installed on the base 1 to the table 11 side) The rotational driving force is continuously transmitted to the attaching drum 21, the transfer drum 24, and the like. In addition, since the heavy motor 31 and the gear box 32 are not attached to the table 11, the movement of the table 11 is smooth and the driving load for the movement is small. And
After moving the table 11 upward and setting the sticking drum 21 to a predetermined position, the label L is stuck to the adherend 8a.

When the label L is attached to the adherend 8a at a position lower than that of the adherend 8 when the label L is attached to the adherend 8a, the rotating shaft 12 is moved in the opposite direction to the above. By rotating the table 11 and moving the table 11 downward, it suffices.
In this way, when changing the adherend, it is possible to arbitrarily set the sticking position of the label L on the transporting means of the adherend.

[0017]

Embodiment 2 In the above-described labeling machine, FIG.
The scale 12 may be attached along the moving direction of the base 1 as shown in FIG. That is, the needle 13 that does not move together with the table 11 is arranged toward the scale 12, and the amount of movement of the table 11 is adjusted by the scale 12 indicated by the needle 13.
Can be confirmed at the position. In addition, if the position of the scale 12 with respect to each adherend is determined when attaching the label, the base 1 can be moved quickly when the adherend is changed.

[0018]

As described above, the present invention has the following effects. <A> Since the sticking drum can be moved up and down with respect to the adherend to be transferred, the position of sticking to the adherend can be set arbitrarily. For this reason, since the label sticking position can be changed, the label sticking position can be used for adherends having different outer shapes, and the usefulness of the labeling machine is improved. <B> By mounting a heavy motor (drive source) on the base below the table instead of mounting it on the table, the table can be moved smoothly and the driving load for the movement can be reduced.
