Description

Automatic Filling and Packing Method and Apparatus therefor}

The present invention relates to an automatic filling packaging method and apparatus.

The strip-shaped film is taken out from the disc formed by winding the strip-shaped film, and the strip-shaped film to be driven is formed into a tubular shape by a forming plate, and the polymerized portion is sealed to form a tubular body. The contents of the cylindrical body are filled, the contents of the cylindrical body are partially pressed and crushed, and the cylindrical body is clamped and conveyed by a pair of clamping press rollers, and the two cylindrical bodies are added to a predetermined proximal position. BACKGROUND OF THE INVENTION An automatic filling packaging device is widely known, which cuts between two clips to obtain a package of a predetermined length, for example, a sausage package.

It can be seen that the package is attached with a tape piece which is easy to hold in order to facilitate the peeling of the packaging (film) when the consumer takes out the contents.

This tape piece is attached to the strip film at a distance interval corresponding to the length of one package before the strip film reaches the forming plate during the filling packaging step. It is set so that a fixed relationship may be maintained between the attachment position of the said tape piece and the position of the said clip cutting of the package body. This setting is made based on the conveyance speed of the said clamping press roller, ie, the motor rotation speed of the clamping press roller. In this way, the tape piece is attached to a predetermined position which is the most easy to grasp and the package is easily removed.

However, the relationship between the attachment position of the tape piece mentioned above and the cutting position of a package may be broken. This relationship is determined on the basis of the premise that the traveling speed of the strip-shaped film and the traveling speed of the cylindrical body in which the contents are filled are the same at any position, and are determined based on the rotational speed of the motor driving the pinching roller.

However, in reality, the clamping roller is clamped and conveyed to the cylindrical body while pressing and crushing the contents, so that slippage occurs between the cylindrical member and the clamping roller and the theoretical conveying speed and the cylindrical body obtained by simply calculating from the rotational speed of the motor. The actual traveling speed does not coincide with each other, and the belt-like film is under tension, and varies with the site, and thus the difference in running speed occurs between the belt-shaped film and the cylindrical body.

As a result, even if the tape pieces are attached to the strip-shaped film at the prescribed timing, the relationship between the gaps between the tape pieces and the cutting position gap of the cylindrical body is distorted, so that the tape pieces do not come to a predetermined position. This means that the product is treated as defective.

An object of this invention is to solve this problem and to provide the automatic filling packaging method and apparatus in which the relationship between the tape piece attachment apparatus and the cutting position of a package is always constant.
