[0001] Automatic labeling device [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic label applicator, and more particularly, to an automatic label applicator capable of attaching a label to a lower portion of a product so as to be applicable to various product shapes and sizes.

Generally, a process of attaching a label printed with information including a product type, a company name, a bar code, a serial number, a delivery destination, etc. is indispensably required in production, packaging, and the like for sale of a product.

A general label is composed of a printing surface on which the information is printed and an adhesive surface on which the adhesive is applied on the back of the printing surface. In the usual way of attaching the label, the operator manually removes the label from the release sheet Respectively. At this time, the worker takes long time to work by confirming the position so that the adhesive side of the separated label can be attached to the precise position of the product, and the label does not stick to the correct position, or the pore between the label and the product Resulting in frequent occurrence of defects.

In order to solve the above problems, Korean Patent Registration No. 10-1269670 (Feb. 31, 2014) discloses a conveying device including a main body located at one side of a conveyer for conveying a product and a label disposed at an upper portion of the conveyor, A supply bobbin coupled to the supply bobbin so as to be rotatable, an attachment frame connected to the main body, a supply guide disposed at a lower portion of the supply bobbin for guiding the supply of the label, An attachment body disposed at one side of the separation body for pressing the label separated from the separation body so as to be attached to the electronic component supplied on the conveyance, And a second guide member disposed on the other side of the supply guide, And a discharge motor connected to the discharge bobbin and fixed to the main body to rotate the discharge bobbin.

However, the conventional automatic labeling machine is located above the conveyor on which the product is conveyed, so that it is difficult to correspond to the size and shape of the product, and as the product is manufactured in a limited space on the line, There has been a problem in that it can not be suitably applied depending on the working environment of the processing line.

In addition, in the case of a product in which a curved surface and an engraved surface are formed on the outer surface of the product, or a product in which various components are combined, it is difficult to adhere the label on the upper surface or the side surface. In order to preserve the aesthetics of the product, There is an increasing demand from sellers to attach the input label to the bottom.

In addition, in a conventional automatic labeling machine, a supply roll on which a label is printed is attached and fixed to a clip on the operation of replacing the release paper with the label attached thereto, and the end of the label started from the supply roll is fixed There is an inconvenience that the operator must perform the manual operation manually in order to perform the work to be performed, and it is not possible to prevent a mistake caused by the worker in the work of replacing the release paper, so that the operator confirms the label attached to the product, A problem has arisen that a work for removing the above-mentioned components is required.
