Description

  The present invention relates to a label sticking device, and more particularly to a label sticking device for sticking a label to a side edge of a product.

2. Description of the Related Art There are plastic containers for storing sweets and the like in which one side of a lid is connected to one side of a container so that it can be bent. In the case of a container with a lid, after an article is accommodated in the container, the open side opposite to the connecting portion is stopped with a label or cellophane tape so that the lid does not open.
In the case of cellophane tape, it is common that the tape is stretched by hand across the container and the lid, but in the case of a label, it is not just to stop the lid from opening, but at the same time the product Since it serves as a display and is produced in large quantities, the above-described manual pasting has a difficulty in productivity and is being mechanized (for example, see Patent Document 1).

The label sticking device is a device for sticking a label to the side end of the product to be transported (open side of the container and the lid). The label sticking device has a label issuing unit above the conveyor for transporting the product. Is fed in the vertical direction, and the fed label and the end of the product conveyed by the conveyor (front end in the conveying direction) are in contact with each other, and the label is attached to the end.
In the label sticking device, when the label is fed out and issued in the vertical direction, the issued label may be warped (curved) in the length direction. For example, air is blown onto the fed-out label. Thus, a method is adopted in which the fed-out label is maintained in a substantially vertical state, and the label is correctly affixed to the front end portion of the passing product.

  However, since an apparatus for injecting air in the issued label direction is required, there is a problem that the entire apparatus becomes complicated and leads to an increase in cost.

  The present invention has been made in view of the above-described problems of the prior art, and the problem is that the label issued in the vertical direction from the label issuing unit has a simple structure and a substantially straight line state at the time of issuance. An object of the present invention is to provide a label applicator that can maintain the above and can correctly apply a label to an end of a product.

In order to solve the above problems, the technical means taken by the present invention is that a product composed of a container and a lid is transported on a product transport unit, the front side in the transport direction of the product is in contact with the label, and the product is labeled A label affixing device for affixing a label roll from a label roll to issue a label, and forming the issued label by curving it in the width direction of the label and maintaining its shape A label curve feeding means provided at a position lower than the label issuing unit and at an upper position than the conveyed product, and is installed below the label curve feeding means. a gap which penetrates vertically at the conveying surface of the product conveyor unit, further, between the label curved feeding means and the product conveying unit, assisting the transport of the goods to be transported by the product transport unit Auxiliary conveying means is arranged, the auxiliary conveying means has an opening that allows the label issued from the label issuing unit to enter the gap, and the product conveyed from the upstream of the commodity conveying unit is: The leading end of the label that is conveyed between the auxiliary conveying unit and the commodity conveying unit and is sent vertically downward from the label curving and feeding unit passes through the opening of the auxiliary conveying unit and the gap of the commodity conveying unit. Located below the transport surface of the product transport section, the product transported to the label comes into contact, and the label is applied across the upper, side, and lower surfaces of the side edges of the transported product while the product is transported. (Claim 1).
The label issuing unit has a printing function, prints predetermined items on label paper, and after printing, the label is peeled off from the mount and fed out, or a label on which the predetermined items are printed is affixed to the mount and applied to the roll. It may be any of the types which are wound, set with the label roll, peeled off from the mount and fed out.
Examples of the shape imparted to the label by the curved feeding means include a mountain shape, a V shape, a U shape, and an arc shape.
