c at the same time by simultaneous pressing of the horizontal partition plates 3a,
The guides 3b and 3c are held.

Next, the supply section 18 of the horizontal partition plates 3a, 3b, 3c will be described. In the figure, reference numeral 19 denotes a magazine portion of the horizontal partition plates 3a, 3b, 3c, in which a large number of horizontal partition plates 3a, 3b, 3c are superimposed, and a cut 4 is formed.
a, 4b are stacked facing each other in the direction of the forming frame 12, that is, the magazine portion 5 of the vertical partition plate 1, and the horizontal partition plate 3a ( 3b, 3c) are configured in advance so as not to fall naturally.

Further, the lowermost horizontal partition plate 3a (3
b, 3c), a drawing rod 21 having a suction cup 20
Is provided, and the lowermost horizontal partition plate 3a (3b, 3b) is provided.
c) is sucked by the suction cup 20, pulled out downward, placed on the lower support rail 22, and then the suction of the suction cup 20 is released.

As described above, the horizontal partition plate 3a (3b, 3c) supplied on the support rail 22 is then placed at a predetermined position at a position facing the cuts 2a, 2b, 2c of the vertical partition plate 1. Automatically supplied.

The details are shown in FIG. That is, each of the inner spaces is set substantially at the horizontal partition plate 3a (3
The endless chains 23 and 24 are provided in two pairs at intervals of b and 3c).

Then, each of the endless chains 2
Cuts 2 of the vertical partition plate 1 over the entire outside of the
a, 2b, 2c at the same intervals as the horizontal partition plates 3a, 3
b, 3c holding rods 25 are provided. Further, the lateral partition plates 3a, 3
A groove 26 for guiding and holding both ends of b and 3c is provided.

In the above configuration, first, for example, the horizontal partition plate 3a supplied on the support rail 22 is supplied and held by the pusher 27 in the groove 26 of the holding rod 25 in a horizontal position with the support rail 22. You.

Next, the inner sides of the endless chains 23 and 24 are raised, and the grooves 26 of the holding rod 25 are raised.
The horizontal partition plate 3a held in the vertical partition plate 1 supplied to the molding frame 12 is raised by an interval between the cuts 2a and 2b of the vertical partition plate 1.

At this time, the next horizontal partition plate 3b previously supplied from the magazine section 19 onto the support rail 22 is pushed by the pusher 27 to the support rail 2
2 and is guided and held by the groove 26 of the next holding rod 25 that has risen to the horizontal position.

Similarly, the next horizontal partition plate 3c previously supplied onto the support rail 22 from the magazine section 19 is moved by the pusher 27 into the support rail 2c.
2 and is guided and held by the groove 26 of the holding rod 25 raised to the horizontal position. The above state is shown in FIG.

As described above, the endless chain 2
The horizontal partition plate 3 held between the holding rods 25 between the vertical partition plates 3 and 24 at the same interval as the cuts 2a, 2b and 2c of the vertical partition plate 1.
The a, 3b, and 3c are simultaneously pressed by the pusher 28 at the same time as the U-shaped formation of the vertical partition plate 1 in the forming frame 12, and are simultaneously engaged as shown in FIGS. Is completed.

Thereafter, the forming frame 12 is rotated 90 degrees, during which the next horizontal partition plates 3a, 3b, 3c are sequentially guided and held between the holding rods 25 between the endless chains 23, 24, and simultaneously. Batch pressing and simultaneous engagement are performed on the vertical partition plate 1 formed in the forming frame 12 located at the upper portion, and the sequence is sequentially repeated.

The above is one embodiment of the method of the present invention and an apparatus for carrying out the method. FIGS. 1 and 5 show a case where the partitioning plate A is automatically filled in a cardboard case C which is a packaging box. An example is shown.

First, the forming frame 12 holding the partition A is rotated by 90 degrees (see FIGS. 5 and 10).
At this stage, the middle partition plate A is in a state of lying down. Therefore, at this stage, the partition board A
When filling the cardboard case, the cardboard case C must also be supplied sideways, which makes handling difficult. This point is part D in FIG.

Next, as described above, the horizontal partitioning plate A is moved by the pusher 29 to the receiving frame 30 held in the horizontal position by the pusher 29 by rotating the forming frame 12 by 90 degrees, and further provided radially. Said receiving frame 3
0 is rotated 90 degrees (see FIGS. 5 and 11). At this stage, the partition A is in the upright state. Therefore, the cardboard case C can be filled as it is. This point is point E in FIG.

However, in the embodiment shown in the drawings, the partition plate A in the upright state is further sent in the right angle direction due to the layout of the feeding device for the cardboard case C and the filling step for the cardboard case C. Corrugated cardboard case C supplied beneath it while standing up at the point
Is rotated 90 degrees in accordance with the transfer direction. This point is point F.

Next, the cardboard case C is transferred to the shutter 31 provided in the transfer direction of the cardboard case C, and is filled in the cardboard case C supplied below (FIG. 12).
And FIG. 13).

[0044]

According to the method and apparatus of the present invention, since the vertical partition plate is automatically formed by one sheet, the handling is extremely easy, and the horizontal partition plates are simultaneously engaged by collective pressing thereafter. Therefore, the assembling of the partition plate can be speeded up.
