The operation of the system of the present invention including the above devices will be described below.

In the present embodiment, a case will be described in which the package to be handled is a cone package, and half of the packages are packed densely with the large diameter part facing down and the other half of the packages are packed with the small diameter part facing down when boxed.

In FIG. 1, the packages produced in the winding machine area (1) are stocked in the stocker (2) in the states shown in FIGS. From one stocker (2a), while one batch of packages is being steam-processed in the steam processing tank (11), they are successively discharged, and the conveyor (4) in FIG.
It is transferred to the boxing station position shown in FIG. At this time, each cone package is transferred with the small diameter side facing down, like the packages (P1) (P2) (P3) in FIG. This is related to the structure of the package gripping device of the packaging robot described above, and the type in which the outer peripheral surface of the package is sandwiched is used in this embodiment. Therefore, when packaging is performed with the package in the same vertical direction, This is because the gripping device (78) of the robot can grip the packages simply by arranging a plurality of the packages (P1) to (P3) shown in FIG. On the contrary, when all the packages are conveyed downward on the large diameter side, if they are left as they are, the gripping device of the boxing robot of this embodiment may have an inverse taper on the gripping surface of the packages, weakening the gripping force and possibly slipping out. In that case, it is troublesome to invert all packages. Therefore, in the system of the present invention, all the packages discharged from the stocker (2) are transferred downward to the small diameter side.

The packages that have reached the conveyor (20) in FIG. 4 are transferred one by one onto the receiving material (21), and the receiving material is transferred to the front surface of the pusher (22) by the fluid cylinder. Next, the pusher (22) advances and pushes the package (P1a) on the receiving material (21) into the covering device (23). At this time,
The film (26) drawn out from the film roll (25) of FIG. 5 becomes a bottomless tubular shape by the first heater (28),
The package is wrapped, then the front end of the film is fused by a pair of heaters (17a) and (17b), and the rear end is completely wrapped by the other pair of heaters (18a) and (18b). (Fig. 9 (P4)) At the same time, send it out onto the mounting plate (50). The heaters (17a) (18a) (17b) (18b) are rotated in one direction by the chains (19a) (19b), and are fused while the films are overlapped.

Then, the transfer plate (31) shown in FIG.
0) The upper packaged package (P4) is transferred onto the conveyor (30) while alternately performing parallel movement and reverse movement. For example, if parallel, reversal, and parallel movements are performed three times, the package (P
5) As shown in (P6) and (P7), alternately invert and align. Further, when a predetermined number of packages (three in this embodiment) are arranged in a line, the movable guide (34) shown in FIG. 6 is actuated and the three packages are transferred to the orthogonal conveyors (33). Move to a fixed position below the robot (39), and move the movable guide (3
Positioning is stopped by 7). Then, the next three packages are similarly transferred onto the conveyor (33) to form the package group (P8 to (P13) in Fig. 9. Further, the four movable guides (37) (37). ) (37) (38) are actuated to correct the posture so that the six packages are in a dense state.The above-mentioned group of packages is then continued by the gripping device (78) of the robot (39) shown in FIG. The package group (PG) shown in Fig. 6 is lifted up as shown in Fig. 9. That is, the robot (39) moves to the upper side of the case (C), and then the lifting body (72) is moved. ) Is lowered, and the grasped package group is collectively accommodated in the case (C). Furthermore, during this period, the packages covered by the aligning device (32) are arranged one after another, as described above. When the partition plate (B) is placed on top of the package group in the case, new The following groups of packages is being placed contained on the partition plate.

In this way, the case (C) in which the packages are accommodated one after another and becomes full is the weight check position (6) in FIG.
It is temporarily stored in the second stocker (9) through the folding position (7) of the lid, the band hanging position (8) and the like. The above operation is repeated until a number of cases commensurate with the steam treatment tank (11) are stored in the second stocker (9).

Subsequently, the case delivered from the second stocker (9) is transferred onto the trolley (10) arranged in front of the processing tank,
All cases of the second stocker are transferred to the carriage (10) and slightly moved to the entrance side of the processing tank, and the cases on the carriage (10) are transferred by the roller conveyor on the carriage or the chain conveyor to the processing tank ( It is transferred onto a roller conveyor of the same size as the above truck in 11). When the transfer is completed, the inlet and outlet doors of the treatment tank are closed and vacuum steam treatment is performed.

As described above, the package produced by the winding machine is
It is covered with a film, housed in a cardboard case, and steam-treated as it is.

In the above-mentioned embodiment, the package is a corn package, but the cheese package can be processed in the same manner. In this case, the transfer device (31) shown in FIG. 7 only performs parallel transfer without inverting.

〔The invention's effect〕
