2. Description of the Related Art Generally, in so-called soft articles (shrinkable articles) such as disposable diapers and sanitary napkins,
These products are integrally packaged (integrated packaging) in a resin film packaging bag. In this case, usually, compact packaging is performed, and the soft articles are stacked, compressed from the stacking direction, and then made into an aligned article, which is filled from the open end of the packaging bag with a filling pusher or the like.

This type of aligned article filling apparatus is provided with a rotary disk type holder mechanism in the transport path of the aligned articles, and the holder mechanism is a rotary disk, and the rotary disk is aligned with the transport path of the aligned articles. A plurality of insertion holes for the aligned articles are formed, and a bucket for holding the open end of the packaging bag in an expanded state is provided on the back side of the rotary plate. Therefore, while rotating the turntable, the packaging bags are sequentially supplied to the filling position of the articles by rotation.

Various types of filling pushers and pinching devices at the article filling position have heretofore been considered.
For example, as shown in FIG. 5, in the conventional filling pusher and the pinching device at the article filling position, the pinching device is the lifting plate 101.
And a pair of pressure plates 10 that can be separated on the lift plate 101.
2, 102. The aligned article 2 is supplied at the lower moving position of the elevating plate 101 and compressed by the pressure plates 102 and 102. Then, in this state, when the elevating plate 101 moves upward to reach the same height as the filling pusher 103, the filling pusher 103 operates to fill the aligned articles 2 into the packaging bag held in the bucket (not shown). is doing.

[0005]

However, in the structure at the filling position in the conventional article filling apparatus,
Although it is necessary to make the difference between the width of the filling pusher 103 and the pressure plate / bucket width smaller than the thickness of the flexible article,
When the filling pusher 103 pressed the aligned article 2, some flexible articles of the aligned article were caught in the gap between the filling pusher 103 and the pressing plate 102, and were damaged (broken, scratched) or left unpressed. Further, when the aligned article 2 is compressed by two pressing plates from the stacking direction and there are two or more stacking rows,
The soft articles in the rows that do not come into contact with the filling pusher 103 may be left behind due to the resistance generated between the pressure plates 102, disturbing the article rows in the rear and eventually causing the filling to be incomplete. Therefore, it is an object of the present invention to provide an article filling apparatus capable of filling a compressed aligned article without damaging or leaving it unpressurized and without disturbing the aligned state.

[0006]

DISCLOSURE OF THE INVENTION The present invention relates to an article filling apparatus for filling an aligned article, which is compressed by two pressure plates from the stacking direction, into the packaging bag by pushing it out between the pressure plates with a pusher. , The pusher has a pair of pop-out guide plates on both sides, which pop out along the inner wall of the pressing plate prior to the pusher surface and which can be narrowed by the time the pop-out is completed. The pinching plate achieves the above-mentioned object by providing an article filling apparatus characterized in that the pinching plate has a groove portion for receiving the projecting guide plate on its inner wall.

[0007]

When the aligned article compressed by the pinching plate is located at the predetermined filling position, the pusher, for example, the filling pusher starts to operate. While or when the pressing surface of the filling pusher reaches the aligned articles of the pressure plate, the pair of ejection guide plates move in the grooves of the pressure plate prior to the filling pusher. Then, as the pop-out of the pop-out guide plates is completed, the width of the pair of pop-out guide plates is narrowed, and the aligned articles are gripped in the pressing plates. In this gripped state, the filling pusher further moves in the filling direction, and the aligned articles are ejected from the opening of the waiting packaging bag via the guide plate. After filling,
The pair of ejection guide plates eliminate the narrowing of the width, open the aligned articles, and start the retreat prior to the filling pusher.
As a result, the aligned articles are filled in the packaging bag without being damaged, left unpressed, or disturbing the alignment.
