Description

  The present invention relates to a label sticking apparatus and a label sticking method, and particularly to a label sticking apparatus and a label sticking method for sticking a label to an inner wall surface of a hollow part of an adherend having a hollow part.

A label printed with a predetermined print is applied to the inner peripheral surface, which is the inner wall surface of the hollow portion of the adherend forming the hollow portion.
For example, Patent Document 1 discloses a label sticking device that sticks a label on the inner peripheral surface of a container in which a hollow portion is formed.
This label sticking apparatus is provided with a sticking head provided with a label holding part having a substantially circumferential surface, and holds a thin rectangular label by sucking air. In addition, the sticking head holding the rectangular thin label is inserted into the container and the roller provided in the sticking head moves radially outward to press the rectangular thin label against the inner peripheral surface of the container. The container is rotated to attach a thin rectangular label.

However, in the case of a label that is long with respect to the axial direction of the container, it may be difficult to press uniformly and the label may be peeled off. In particular, when the height of the container is high in the axial direction, there is a problem that the label cannot be uniformly pressed and the label is peeled off.
In addition, if the inner peripheral surface of the container is pressed strongly in order to reliably apply the label, the container may fall over and the label may not adhere to the container.

Next, operation | movement of the label sticking apparatus 1 is demonstrated based on the flowchart of FIG.
In step S1, when the label adhering and pasting mechanism 4 is located at the label receiving position, the label 52 printed by the printer unit 2 is peeled upward by the peeling plate 15, and the suction plate 24 sucks the label 52. Then, it progresses to step S2, and when the label 52 is not attracted | sucked by the suction disk 24, it returns to step S1 and the process of step S1 is repeatedly performed.

In step S2, the main cylinder 20 is driven and controlled by the main cylinder controller so as to move the label adhering and pasting mechanism 4 to the upper position of the winding core P (substantially central portion of the hollow portion Pa), and the process proceeds to step S3.
