Description

The present invention relates to a multi-row filling and packaging machine.

A multi-row filling and packaging machine is known in which a tubular packaging bag made of synthetic resin formed in multiple rows is filled with an object to be filled such as food or a pharmaceutical product (for example, Patent Document 1). In this type of multi-row filling and packaging machine, the raw film is cut in parallel in the length direction to form a plurality of strip-shaped divided films. Then, each of the divided films is wound in the width direction by a former to form a tubular shape, and the overlapped portions are appropriately sealed to form a packaging bag having an open portion at one end. The package to be filled is filled in the package bag thus obtained, and then the seal (seal) of the open portion and the other package bags connected in the length direction are cut to form one bag. A filled packaging bag filled with an object to be filled is obtained for each.

In such a multi-row filling and packaging machine, when moving a plurality of divided films to the corresponding formers, if they are arranged side by side in parallel with each other with a width similar to the width of the original film, the entire multi-row filling and packaging machine is used. There was a problem such as an increase in size.

Therefore, for example, when moving a plurality of split films arranged in parallel with each other, a guide plate including an inclined portion inclined at an angle of 45 ° with respect to the longitudinal direction (traveling direction) is used to change the traveling direction. Attempts have been made to reduce the width of a plurality of split films arranged in parallel by converting the films by 90 ° on the way and by superimposing adjacent side edges on each other and bringing the divided films closer to each other. (See, for example, Patent Document 2).

Japanese Unexamined Patent Publication No. 2011-105346 Japanese Unexamined Patent Publication No. 6-179425

In the conventional multi-row filling and packaging machine, in order to change the direction of the divided film by 90 °, the divided film is wound from the upper surface side of the guide plate to the lower surface side of the guide plate via the inclined portion. Therefore, it may be difficult to stably feed the plurality of divided films to the downstream side due to the influence of the frictional resistance between the divided film and the guide plate. For example, if the split film is pulled downstream with an unnecessarily large force, the split film may be stretched in the longitudinal direction.

Further, in the conventional multi-row filling and packaging machine, since the mechanism for changing the direction of the divided film is complicated, the work of attaching the divided film to the divided film is troublesome and has become a problem. In particular, it is difficult to adjust the feeding amount of the divided film, which has been a problem.

An object of the present invention is to provide a multi-row filling and packaging machine having a moving device capable of easily adjusting the amount of feeding of each divided film to the downstream side while keeping the total width of a plurality of divided films arranged in parallel small. be.
