DETAILED DESCRIPTION OF THE INVENTION The present invention does not use a suction drum. The adhering drum must adsorb on the opposite side of the glue surface to activate the glue.If the adsorbing drum is removed, the necessary information will be printed on the opposite side of the glue surface of the label. Can not do it. In other words, conventionally, a sticking drum that sucks the glue surface is used, printing is performed on the side opposite to the glue surface of the label on this drum, the defective label is detected and eliminated, the label is reversed, and the glue surface is attached to the sticking drum. Since the glue was activated by adsorbing the opposite side of the sheet, a suction drum was necessary. The present invention prints the necessary items on the label by a printing device, a print inspection device, and a cutter arranged on a plane before the label arrives at the application drum, sends the label to the application drum by a feed roll, detects, and applies the label. Since the individual label pieces are cut by a cutter at a position close to the drum or on the sticking drum, the suction drum is not required. The position of the cutter must be such that at least the front end of the label piece is in contact with the suction hole of the sticking drum when viewed from the feeding direction of the cut label. This is because if it is not at this position, the cut label piece will not be attracted to the sticking drum.

As the cutter provided at a position close to the sticking drum, a cutter comprising a cutting blade and a cutter comprising a roll which comes into contact with a rotary blade with a label sheet interposed therebetween is used. As a cutter that is not installed on the sticking drum, a patch plate provided near the suction hole at the rear of the sticking drum, a cutter including a cutting blade, or the like is used. The necessary items are printed in this manner, the print inspection is performed, and the label pieces cut individually are sucked and held by the suction holes of the sticking drum on the surface opposite to the glue surface. The suction holes of the sticking drum are connected to a reduced-pressure suction device that applies reduced pressure to apply suction force. The most common vacuum suction device is a vacuum pump.

[0007] In the present invention, the defective label in the label cut by the cutter and fed to the sticking drum is removed and discharged by a defective label discharge device provided at a position forward in the traveling direction from the feeding position. The defective printing label discharge device is provided along the surface of the sticking drum, and is a screver or a suction device that is activated by a signal from the print inspector. In the case of a suction device, a suction device that suctions a defective printing label is used. Also, when a defective label arrives at the position of the discharge device in response to a signal from the print inspection device, the suction is stopped to facilitate removal and discharge. It is not necessary to stop the suction device in the case of a screver.

In the present invention, the heat-sensitive adhesive activating device disposed on the peripheral edge of the sticking drum in front of the printing defect label ejector in the traveling direction and facing the drum surface activates the heat-sensitive adhesive by heating. Appropriate means such as hot air heating and heating with a halogen lamp are used. For example, near infrared rays may be a heating device. However, heating with hot air has many problems, such as noise, exhausting a large amount of generated hot air, and low heating efficiency. On the other hand, heating a halogen lamp has a problem in that the heat absorption of paper in the near-infrared wavelength region generated by the halogen lamp is high. Is 1
There is a problem that it is unsuitable for a high-speed labeler because it is extremely low, that is, about 40%. Since the base material of the label is paper, if the heat absorption rate is low, there is a problem that activation of the heat-sensitive adhesive requires a long time.

The most preferred thermal glue activation device is a far infrared radiation heating device. The heating device provided opposite to the outer periphery of the attaching drum has at least 1 /
It is preferable to be provided so as to surround over 3 for the activation of the glue and the speed of labeling. As the far-infrared radiation heating device, a commercially available ceramic far-infrared heating device that emits heat rays from a heating element by converting the wavelength into far-infrared rays using a ceramic layer is used. Specifically, a thin metal strip is used as a heating element, a ceramic layer is provided on the surface of the heating element, and far-infrared rays are emitted by energizing. A far-infrared radiation heating device can also be arranged on the sticking drum. In this case, a ceramic layer is provided on the outer peripheral surface of the sticking drum, an induction heating coil is placed inside the drum, and far-infrared rays are radiated from the ceramic layer by energizing the drum to activate the heat-sensitive label paste. I do. Of course, both heating devices may be provided in parallel.

As ceramics that emit far-infrared rays,
For example, a far infrared heating system manufactured by NGK Insulators, Ltd. is used. The wavelength from the far-infrared radiation heating device is 2.
Far infrared rays of 5 μm to 25 μm are radiated, and the heat absorption rate of paper at this wavelength is about 80%, which is very suitable for heating paper-based objects such as labels, and heat-sensitive adhesive can be applied in a short time. This is because it can be activated. This is much better than the near-infrared paper having a heat absorption of about 1 to 40%.
The label in which the glue is activated advances to a position where the adherend is sent by the rotation of the sticking drum. The adhered object is pressed by an attaching drum by a pressing device and adheres the label while rotating. A simple pressing device using a known device is preferably an arc-shaped pressing guide or pressing roll along the surface of the sticking drum. Then, at the stage where the label arrives at the position of the pressing device and the adhered object is pressed, the suction device stops the suction, thereby facilitating the sticking of the label.
