The carton transfer path 3 and the envelope transfer path 4 are arranged side by side, overlapping each other vertically. The carton transfer path 3 is a path for transferring the cartons 5, as will be described later.

Further, the package transfer path 4 is a passage for transferring the bottle group 6a, which is an example of the package. The transport speed of the carton 5 and the transport speed of the bolts 6 are constant.
The package accumulation packaging machine 1 also includes a conveyor device 7, a sorting device 8, an insertion lifter device 11, a support device 12, a bottom lid forming device 13, a carton magazine 14, a top lid forming device 15, and a carton transfer device 16. There is.

The conveyor device 7 is for supplying bottles to the inlet section 17 of the packaging station 2. The conveyor device 7 has a passage 18 in which the bottles 6 are conveyed by means of a conveyor. The timing of conveyance is adjusted by the timing screw 21. aisle 18
There are two passages 18a and 18b at a branch point 22 on the way.
It branches to reach the entrance portion 17 of the packaging position 2. Switching at the branch point 22 is performed by a diverter lever 23. The bottles 6 conveyed to the two passages 18a, 18b pass through the star foils 24a, 24 on the way.
The direction is changed by 90° by b and the entrance part 1
7 will be collected.

A sorting device 8 sorts a total of six bottles 6 from a large number of bottles 6 gathered at an entrance part 17 of a packaging position 2 in a state where they are arranged in two columns and three rows. The sorting device has gripping members 25a and 25b that approach and separate from both sides of the two passages 18a and 18b, and the gripping members 25a and 25b approach and cooperate to grip the six bottle groups 6a. and distinguish it from others.
On the other hand, the carton transfer device 16 sends out the carton 5 with its bottom open into the carton transfer path 3 directly above the envelope transfer path 4 and causes it to run. The insertion lifter device 11 includes a lifter table 27 that is located directly below the envelope transfer path 4 and is movable along the envelope transfer path 4 and is movable up and down. The lifter table 27 can place the group of bottles 6a, can move at the same speed as the moving speed of the carton 5, and can move up and down guided by the cam 28. When the lifter table 27 rises, the bottle group 6a placed thereon is pushed up and inserted into the carton 5 from the open bottom of the carton 5.

The support device 12 is for supporting the bottle group 6a and positioning it in the carton 5 until the bottom opening of the carton 5 is closed when the lifter table 27 is lowered after being raised. A plate 29 projects into the bottom opening of the carton 5 and supports the bottom of the bottle group 6a.

The bottom lid forming device 13 is a folding guide 31
Then, the folding hammer 32 forces the bottom lid flap 33 of the carton 6 to close the bottom opening of the carton 5, and the gluing device 34 glues it.

Note that the upper lid forming device 15 is attached to the carton 5.
Prior to supplying the carton to the packaging position 2, the top flap of the carton is folded to close the top opening of the carton.

[Operation] The operation of packing bottles in the stacking packaging machine configured as described above will be explained.

First, the bottles 6 are supplied in one row in the passage 18.
is divided into two rows by the diverter lever 23.

Next, use the star foils 24a and 24b to
Turn the bottle 6 placed in a and 18b by 90°.

Next, a sorting device 8 separates the large number of bottles 6 into two columns and three rows, a total of six groups 6a.

During this time, the suction cup 35 is removed from the carton magazine 14.
The folded carton containing 6 pieces taken out by is pressed diagonally and assembled into a three-dimensional structure, the top cover is closed, and the carton is fed into the carton transfer section 3 with only the bottom open. The cartons and bottle group 6a thus sent are synchronized and simultaneously advance at a constant speed. The bottle group 6a is transferred from the sorting device 8 to the lifter table 27, and the bottle group 6a
is gradually pushed up as it progresses, and carton 5
is inserted into the carton 5 through the bottom opening.

After the insertion, the lifter table 27 descends according to the cam curve, but the support device 12 does not hold the bottle group 6 until the bottom of the carton 5 is closed.
The bottom of bottle a is supported from both sides to prevent the group of bottles 6a contained therein from falling. Finally, the bottom opening of the carton 5 is closed by the bottom lid forming device 13, and the product is discharged out of the machine.
