The conveyor means for supplying the product and the film includes a supply side conveyor 15 for conveying the product, a first subsidiary conveyor 19 and a second subsidiary conveyor 26 for conveying the film and the product supplied into the inside together; The discharge side conveyor 41, which finally delivers the finished product, has a structure in which the discharge side conveyor 41 is arranged in series (from right to left in the drawing). At this time, the second subsidiary conveyor 26 and the discharge side conveyor 41 are connected by one belt.

The film loading device 1 for supplying the film is disposed next to one side of the first subsidiary conveyor 19 and serves to supply the film in a 90 ° direction with respect to the conveying direction of the film. The film inverting apparatus 3 disposed opposite to serves to convert the film in parallel with the conveyor advancing direction, and to feed and cut the film containing the product in the longitudinal direction. The cutting device 4 is sequentially arranged after the film reversing device 3, and the film secondary cutting device 5 for cutting in the width direction of the film is divided into two parts of the second subsidiary conveyor 26. It is disposed between the rear end section and the discharge side conveyor 41.

Accordingly, the film is continuously supplied from the film loading device 1, and the film is switched by the film reversing device 3 in the conveyor traveling direction and then extended to the film feeding / primary cutting device 4 in the first state. When the product is supplied from the supply side conveyor 15 which operates simultaneously with the operation of the drive motor 14, the product is automatically received into the two-ply film on the first subsidiary conveyor 19, and thus the product is accommodated. One longitudinal direction of the film is cut and fused in the film feeding / primary cutting device 4, and then proceeds along the second subsidiary conveyor 26, and then the width direction of the film in the film secondary cutting device 5 The product, which has been cut and fused, and thus the final packaging is discharged through the discharge side conveyor 41, is then processed into a shrink wrapper (not shown) which is a process.

On the other hand, the film remaining pieces cut off from the film feeding / primary cutting device (4) is installed on the rear end side of the main body 100 while receiving the power from the drive / motor (6) side to recover the film pieces to rotate It is wound around the drum 42 and recovered.

As described above, the product packaging apparatus provided in the present invention can continuously perform each step continuously from the progress of the conveyor and the supply of the film to the cutting and packaging, so that the full automation of the packaging work can be realized. do.

Figure 2 is a perspective view showing a drive / motor drive of the product packaging apparatus according to the present invention.

As shown in FIG. 2, the drive / motor 6 uses the power generated from the first and second drive motors 14 and 31 to supply the respective devices (supply side conveyor, first and second auxiliary conveyors, discharge). Side conveyor, film loading device, feeding / first cutting device, film scrap recovery drum) can be driven at the same time.

To this end, the second driving motor 31 is installed at the bottom of the main body 100, and two transmission shafts 32a, 32b, which are supported by bearings at positions away from the predetermined distance, are installed side by side. , The sprocket mounted on the shaft of the second drive motor 31 and the sprocket mounted on the adjacent electric shaft 32a are connected to each other in a chain so that each device (first, second auxiliary conveyor, discharge side conveyor, Power can be distributed and delivered to the film loading device, feeding / first cutting device, film scrap recovery drum).

Three sprockets are mounted on the transmission shaft 32a, one for receiving power from the second driving motor 31, and the other for driving the film scrap recovery drum 42. One is for powering the coaxial 32b, and the other is for powering the devices (first and second subsidiary conveyors, discharge side conveyors, film loading device, feeding / first cutting device).
