Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for fitting a bag-like label onto a bottle from above.

[Conventional technology]

A plastic film tube (hereinafter referred to as a "tube") is fitted onto the body of a glass or plastic bottle as a label, and then the tube is heat-shrinked to tightly fit it around the body of the bottle. It is known to do so. It is also known to fit a tube over the neck spout of a bottle and heat-shrink it to make it tightly adhere to the neck spout to form a cap seal.

The operation of attaching a tube to a bottle involves unwinding a long tube wound on a roll from the roll, cutting off the tip of the tube to the required length, and placing it on the bottle or covering it with the bottle. This is done by cutting it to the required length. In either case, since the tube unrolled from the roll is folded flat, it is necessary to open it into a cylindrical shape when covering the bottle. Also, if the tube has a small diameter,
It will be difficult to fit it into the bottle, and if it is too large, there will be bagginess even after heat shrinking and it will not be possible to fit it tightly to the bottle, so choose an appropriate diameter that takes into account the ease of fitting it into the bottle and the heat shrinkage rate. A molded one is used.

[Problem that the invention attempts to solve]

When the tube is placed over the spout from the body 3a of the bottle 3 to the spout of the neck 3b as shown in FIG.
can serve as both a label and a cap sticker. However, since the neck part 3b has a smaller diameter than the body part 3a of the bottle, when using a tube T with a large diameter that can be fitted onto the body part 3a, the tube T may be subjected to heat shrinking treatment. , trunk 3
Although it is possible to tightly attach the tube with sufficient tightening force to the tube a, there is a limit to the amount of heat shrinkage of the tube. In order to make the tube T adhere to the top surface of the bottle with a uniform and sufficient contraction force, the cross-sectional diameter of the part that covers the neck should be made smaller according to the change in the outer diameter from the body of the bottle to the neck. It is necessary to use a tube with a chevron-shaped top. Also, neck 3
In order to cover the zenith surface of the tube T, it is necessary to seal the top open end To of the tube T and form it into a bag shape.

However, it is extremely inefficient to prepare a large number of bag-shaped tubes with a chevron-shaped top ("bag-shaped labels") and then fit them onto each of a large number of bottles. A complicated and large-scale device is required to automate the process of opening a bag-like label into a cylindrical shape and fitting it onto a bottle while maintaining the open state.

The present invention has been made to solve the above problems.

[Means and operations for solving problems]

The present invention uses a regular long tube with a fixed folding diameter, and while feeding the long tube along the tube feeding line, the tip of the long tube is fitted onto the bottle. The operation of processing and cutting off the tip of a long tube into a bag-like label is continuously and repeatedly performed on each of a large number of bottles.

In other words, the bag-like label attaching device of the present invention can hold a long tube with a constant diameter when folded flat.
While pitch-feeding with a feed amount that includes the cutting length of the bag-like label to be cut from the tip, the tip is fitted onto a bottle fed into the bottle waiting section of the bottle conveyance line, and the tip is fitted onto the bottle. In a bag-shaped label attaching device that forms a bag-shaped label with a chevron-shaped top that is fitted onto a bottle by cutting off the tip of a long tube with a chevron-shaped fusing line, the bottle is placed on standby on a bottle conveyance line. legs 43, 43, which are held in the long tube to open the long tube in a cylindrical shape, are generally shaped like a figure eight in normal conditions, and open and close by elastic deformation;

When the transfer of the tube T is stopped, the portion Q directly above the bottle is closed flat, and in this state, the tube T is fused along the fusion line 100. By fusing and cutting, a bag-shaped label 200 having a chevron-shaped top is obtained from the tip T' of the tube in a state where it is fitted onto the bottle 3. At approximately the same time as or immediately after the melt cutting, the remaining material portion 300 is cut off along the remaining material cutting line 400. The cut-off excess material is removed from the area to the outside. The reason why the surplus material portion 300 is cut along the surplus material cutting line 400 is to make the hem cut edge of the next bag-shaped label 200 horizontal.
