and a suppression plate 73b which is movably inserted into the chute 72b and is operated by a cylinder 74b to press the buffer plate P2.
The first buffer plate P2 is inserted between the items by being pressed laterally.

In FIG. 6, the second buffer plate insertion mechanism 8 inserts the first intermediate conveyor 3 and the second intermediate conveyor so that the tip thereof is directly above the relay point between the first intermediate conveyor 3 and the second intermediate conveyor. A large number of vertical buffer plates P3 are provided on the top of the transfer mechanism 6.
Magazine 8 which is designed to accumulate in the posture at the time of insertion.
1 and a buffer plate P3 provided at the front of the magazine 81.
a chute 82 that guides the descent of the buffer plate P3; and a suppressing plate 83 that is inserted into the chute 82 so as to be movable up and down and is operated by a cylinder 84 to press down the buffer plate P3.
The second row item is intermittently stopped together with buffer plates P1 and P2.
After being transferred between the feed plates 41 and 420 of the first intermediate conveyor 3, the suppression plate 3 is lowered while the second row of items is sent to the terminal position of the first intermediate conveyor 3 and is stopped intermittently. Then, the first buffer plate P3 in the magazine 81 is placed in the middle position between the two intermediate conveyors, and the items in the first row and the second,
It is inserted at a position between the items in the row as shown by the broken line.

In FIG. 3, the cart/supply mechanism 9 includes a magazine 91 capable of stacking a large number of flat cartons C having a shape as shown in FIG. 7 in an upright state with the bottom side facing down in FIG. A suction separation lever 93 is swingably attached to the frame 92 of the magazine near the outlet end of the magazine 9 (7) (the left end in FIG. 3) and is equipped with a suction cup 94 that can suction and hold the carton C at the forefront of the magazine. and a plurality of pairs of feed rollers 95, 96, and 97 that send one cart taken out by the adsorption/separation lever 93 to a predetermined position, that is, to the side of the terminal end of the second intermediate conveyor. The adsorption/separation lever 93 is moved by operating a lever 98 using an actuating device such as a cam or a cylinder.

In FIGS. 3 and 8, the packaging mechanism 1o includes a pair of horizontal upper and lower regulating plates 101 which are provided on the side of the terminal end of the second intermediate conveyor 4 so as to be movable up and down at a predetermined interval from each other. .1
02, a side regulation plate 103 arranged and fixed adjacent to the side of the vertical regulation plate 101.102, and upper and lower guide plates 1 provided between the intermediate conveyor 4 and the regulation plate 101.102.
04.105, an upper flap bending arm 106 rotatably supported by a frame (not shown) etc. at the upper part of the upper regulating plate 101, and an upper flap bending arm 106 rotatably attached to the frame etc. at the lower part of the lower regulating plate 102. The left and right pair of front lid bending arms 107 and the lower regulating plate 1020 are located below both sides of the lower regulating plate 1020 and touch the side edges when they are lowered. It is bent as shown in FIG. 8 against a pair of provided flap forming members 109 (only one is shown in FIG. 3).

Next, the upper flap bending arm 106 rotates to bend the upper flap C as shown in FIG. 9 [C], and then the front lid forming member 107 is rotated as shown by the arrow in FIG. The front lid e and the flap h continuous therewith are formed as shown in the figure. At this time, the flap C and the front lid e are joined together because an adhesive has been applied to the joining surface of the flap C in advance.

Next, the upper and lower regulating plates 101 and 102 simultaneously begin to descend.

When the vertical regulation plate descends, the pair of side lids f are bent by the side lid molding member 10B and stop at a position -0 which has descended to approximately the same level as the take-out conveyor 120 provided adjacent to the cartoning mechanism. Then, the flaps f and h, to which adhesive has been applied in advance, are joined to the side lid, and the packaging operation is completed (FIG. 9 [E]).

After the packaging work has been completed, the boxed objects are pushed out onto the take-out conveyor 120 by the pushing member 121, and
Retrieved by 0.

Next, the overall operation of the automatic packaging apparatus according to the present invention will be explained based on FIG. 10.

The item M sent to the end of the intake conveyor 2 is transferred to the transfer mechanism 5
A plurality of conveyors (three in this embodiment) are simultaneously pushed between the pair of feed plates 31 and 32 of the first intermediate conveyor 3, which is intermittently stopped, by the suppression plate 51. When the feed plate 3-1.32 of the intermediate conveyor 3 moves intermittently and stops intermittently at the buffer plate insertion position, the two parts of the first buffer plate insertion mechanism 7 operate simultaneously to insert a row of buffer plates between the items M. Insert P1 and P2 at the same time. Next, the feed plate 31, 32 of the intermediate conveyor 3
When the product M with the buffer plate inserted therein moves intermittently and stops at the end position of the intermediate conveyor 3, the press plate 61 of the transfer mechanism 6
operates to push the item, together with the buffer plates Pl, p, 2, between the pair of feed plates 41 and 42 of the second intermediate conveyor 4, which is intermittently stopped.

When the next M row of items is intermittently transferred to the terminal end of the first intermediate conveyor 3, there is a gap between it and the row of items that have already been transferred between the feed plates 41 and 42 of the second intermediate conveyor 4. In this case, a column of buffer plates P3 is fed by a second buffer plate supply mechanism, after which the pressing plate of the transfer mechanism 6 operates to transfer the row of items on the intermediate conveyor 3 between the feed plates of the intermediate conveyor 4. Therefore, on the intermediate conveyor 4, the items M are arranged in two rows with buffer plates Pl, p2, and P3 interposed between them. The data is sent intermittently.

When the articles M arranged in two rows are sent to the terminal end of the second intermediate conveyor 4, the pushing member 110 operates to push the articles into the carton C together with the pair of vertical regulating plates 101 of the packing mechanism.
and 102, the product operates as described above to complete the packaging of the product.

As described above, according to the present invention, it is possible to provide a device that can automatically pack and package items by stacking them together with a buffer plate.

In the above embodiment, the cartons are folded and packed into boxes, but a carton that has been folded into a box shape is supplied adjacent to the end of the intermediate conveyor, and the items are pushed into the carton together with a buffer plate. You may also do so.
