Hereinafter, the product to be labeled will be described by way of example with containers such as cooking oil and beverages.

Such a labeling device includes a labeling device having a conveying device for conveying a container, a labeling drum for attaching a label to a container conveyed by the conveying device, and a label supply device for supplying a label to the labeling device. do.

And, the labeling machine is divided into a rotary type and an inline type according to the method of the transfer device for transferring the container.

The rotary type labeling machine includes a rotary table which rotates in a mutually opposite direction in contact with the labeling drum and rotatably transports the container so that the label is attached, and a plurality of rotary tables which are provided in the rotary table to rotatably support the container with respect to the rotary table. A container stand is provided. That is, in the rotary type label attaching machine, the container to which the label is to be attached is provided to be rotated by the container mounting stand at the same time as the container is revolved. However, the inline type labeling device is configured such that the container is rotated by the labeling drum in contact with the labeling drum and the label is attached, such as a rotary table and a container mounting table for rotating and rotating the container such as a rotary type labeling device. It is not prepared separately. Then, the inline type labeling machine attaches the label to a container having a mainly circular cross section so as to be rotatable in contact with the labeling drum.

In the following description, an inline type labeling machine will be described as an example.

The conventional inline type labeling machine is disclosed in Korean Patent Publication No. 1992-0004525.

Such a conventional labeling machine includes a conveyor and a star wheel for supplying a container to attach a label, an application drum for attaching a label to a container transported by the star wheel, and a supply roller for supplying a label sheet in an application drum direction. , A rotary cutter for cutting the label sheet supplied by the supply roller is provided.

However, the rotary cutter provided in the conventional labeling machine has only a function of cutting a label sheet and does not have a function of supplying a sheared label to the application drum. Therefore, a separate means for supporting and feeding the label sheet is not provided between the supply roller on which the rotary cutter is located and the application drum, so that the label sheared by the rotation cutter is not easily adsorbed on the application drum. If the label is attached to the container in a state where the label is not correctly adsorbed on the application drum, there is a problem that the label attachment position of the container is not accurate. In particular, when it is necessary to attach a short label, such as a small diameter container, because the length of the cut label is short, there is a problem that the sheared label is more difficult to be accurately adsorbed on the application drum.

In addition, the conventional labeling machine is not provided with a means for supporting the label sheet between the supply roller and the application drum, there is a problem that it is not easy to use a label of a thin material such as vinyl.

Accordingly, it is an object of the present invention to provide a label applicator that can not only accurately label a product, such as a container, but also can accurately label an article, especially for short labels. And, it is to provide a labeling machine that is easy to use thin labels, such as vinyl.
