Further, the distance between the parallel edge portions 41c and 42c facing each other is set according to the width of the pointed portion 1b of the bag-packed product 1 (a direction perpendicular to the extrusion direction Y in FIG. 4A).
[0041]
The extrusion plate 4 of the boxing device configured as described above has the following operations and effects.
[0042]
When the group of fins 2a on the alignment conveyor 2 stops at the article extrusion position and the extrusion plate 4 moves in the extrusion direction Y, the first and second stabilizers 41 and 42 are as shown in FIG. It inserts between each bagging goods 1 so that it may pinch | interpose from the both sides of the conveyance direction X of each bagging goods 1. FIG. That is, each packaged product 1 is accommodated between the first and second stabilizers 41 and 42. At this time, the leading ends of the first and second stabilizers 41 and 42 reach the middle of the extrusion direction Y on both sides of the bagged product 1 as shown in FIG. Further, the oblique sides 41 b and 42 b of the first and second stabilizers 41 and 42 are in contact with the inclined portions 1 a of the bagged product 1, respectively. As a result, each of the oblique sides 41b and 42b supports half of the bag-packed product 1 on the side of the extrusion plate 4 and restrains the posture of each bag-packed product 1. Thereby, each 1st and 2nd stabilizer 41 and 42 can hold | maintain the attitude | position of each bagging goods 1. FIG. Thereafter, the push-out plate 4 can freely open and close each bag-stuff 1 via the intermediate body 11 while restraining the posture of each bag-stuff 1 accommodated between the first and second stabilizers 41, 42. Are transferred to the damper plates 12 and 12. By the above, it is suppressed that the attitude | position during the transfer of the bagging goods 1 is disturb | confused.
