[0029]
In the labeling apparatus 1 configured as described above, each label forming substrate R supplied by each label forming substrate supply means 10 is sequentially cut by each cutting means 20 so that two sheets of a predetermined length are obtained. The two labels L are supplied to the sticking drum 31 by the respective label delivery means 40. At this time, as described above, the label delivery means 40 positions each label L to be supplied in the vertical direction, and the positioning in the front-rear direction, that is, the supply timing of the label L is adjusted. The two labels L are sucked and held at a predetermined height position on the outer peripheral surface of the sticking drum 31 with a predetermined interval always provided.
[0030]
The two labels L sucked and held on the outer peripheral surface of the sticking drum 31 in this way are conveyed to the label sticking position α by the rotation of the sticking drum 31, and are heated by the infrared heater 33 in the middle thereof. It will be in the state where adhesion is possible.
[0031]
The two labels L in an adhesive state that have been transported to the label sticking position α are transported by the bottle transport means 50 and contacted with the outer peripheral surface of the sticking drum 31 while rotating to rotate the label sticking position α. By being wound around the outer peripheral surface of the bottle B that moves, the bottle B is attached to a predetermined position (front and back).
[0032]
As described above, the labeling device 1 configured as described above conveys the label L to the adhering drum 31 by the label conveying belt 42 stretched around the pulleys 41a and 41b. By reducing the diameter of the pulley 41a, the cutting position β by the cutting means 20 comprising the fixed blade 21 and the rotary blade 22 can be set in the vicinity of the label conveying belt. Therefore, even a label with a short cut pitch can be reliably delivered to the label transport belt 42, and can correspond to labels of various lengths with different cut pitches.
[0033]
Further, in order to speed up the labeling operation, even if the rotation speed of the sticking drum 31 and the moving speed of the label transport belt 42 are increased, the label L can be secured by sufficiently securing the distance between the pulleys 41a and 41b. The distance necessary to perform the positioning process can be secured sufficiently, so that the suction drum can be used to cope with the speeding up of the labeling work, as in the conventional labeling device that delivers and positions the label by the suction drum. By increasing the diameter of the label, it is possible to speed up the labeling operation of a label having a short cut pitch without causing a problem that the delivery of the label having a short cut pitch becomes more difficult.
[0034]
In this embodiment, in order to stick two different labels L to the bottle B, the labeling apparatus 1 having two sets of label forming base material supply means 10, cutting means 20, and label delivery means 40, respectively. Although it demonstrated, it is not limited to this, You may stick 1 or 3 or more labels to the bottle which is a to-be-adhered body. However, in that case, it goes without saying that the label forming base material supply means 10, the cutting means 20 and the label delivery means 40 must be provided in the same number as the number of labels to be attached.
[0035]
Moreover, although this Embodiment demonstrated the case where the to-be-adhered body of the label L was a bottle, an to-be-adhered body is not limited to a bottle, It applies to various things, such as a bottle and a can. Can do. The adherend may be any member that can wrap the label along the outer peripheral surface of the sticking drum 31, and the sticking portion of the label is applicable to various shapes such as a circle and an ellipse. can do.
[0036]
【The invention's effect】
As described above, the labeling device according to the present invention is configured so that the label is transported by the label transport belts hung on the pulleys installed on the cutting means side and the sticking drum side, respectively. By sufficiently securing the distance, it is possible to secure a sufficient distance required for the label positioning process, and by reducing the pulley installed on the cutting means side, the cutting means is provided in the vicinity of the label conveying belt. It becomes possible to install.
[0037]
Therefore, it is possible to deal with any label from a label with a long cut pitch to a label with a short cut pitch, and even if the moving speed of the label conveying belt is increased in order to speed up the labeling operation, Positioning can be performed sufficiently and reliably.
