[Industrial applications]

 In this invention, labels that are continuously attached on a continuous mount so that continuous printing can be performed are peeled off one by one after the printing, and are attached to a desired label-attached object. In the label applying machine, when the label is attached to the object to be attached by spraying after adsorption, it tries to selectively block the jet air outlet according to the size and shape of the label. It relates to a jet air spray control mechanism.

[Prior art]

 As is well known, label information display processing is often used as a means of transmitting information in various industrial fields. This type of label is generally stuck on a continuous mount in a printer such as a computer so that it can be printed continuously, and is peeled off one by one from the continuous mount after the printing process. It is designed to be pasted on the target object.

As described above, various label sticking machines are used as a device for peeling labels, which are intensively printed by a printer device or the like, from a continuous mount and sticking them on an object. It has been developed and provided. This type of label sticking machine changes the spraying state to the label depending on the feeding state of the label peeled from the continuous backing sheet, or the property of the target object (uneven form of the label sticking surface, the target object is destroyed). (If it is easy to break), etc., it must be compatible without distinction.

[0004]

[Problems to be solved by the device]

 Conventional label applicators peel off labels one by one from a continuous backing sheet, once adsorb and support the peeled labels, and then blow air with a stronger force than the adsorbing force. The label is attached to the labeling surface of the object. This conventional label sticking machine is composed of a relatively large label suction plate so that a relatively large label can be sucked and stuck regardless of the size and shape of the label. In this case, if the label to be processed is relatively small, or if the label has a shape that is significantly different from the shape of the label suction plate, when jetting air, part of the jetted air (label It has been pointed out that this is a major problem in that the outer part) is directly blown onto the object to be labeled with no load, causing an obstacle to the object to be labeled.

Therefore, the present invention is intended to solve the drawbacks and problems found in the above-mentioned conventional label sticking machine, and to eliminate unnecessary jet air depending on the size and shape of the label to be processed. The jet air blowing control mechanism in the label sticking machine is designed to selectively block the jet air blowing port.

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this invention is, specifically, to perform after printing processing a label group continuously attached on a continuous mount so that continuous printing processing can be performed by a printer device or the like. The labels are peeled off one by one from the continuous mount, and the peeled labels are once adsorbed and supported by the label adsorbing means. A label sticking device for sticking onto a label sticking object, comprising: a plurality of slit openings having a label sucking surface for sucking and supporting the label, and opening toward the label sucking surface. A label suction plate having a row; and a chamber structure that communicates with a slit opening row in the label suction plate to form a suction flow path, In the suction flow path of the chamber structure, jet air blowing flow path means for blowing jet air to the label sucked and supported on the label suction surface is provided, and the slit opening row in the label suction plate is provided. In a label sticking machine in which jet air is blown out through the jet air, jet air for selectively closing the jet air blowout port in the jet air blowout flow path means according to the size and shape of the label to be processed. It constitutes a jet air blowing control mechanism in a label sticking machine provided with a blowout port closing means.
