Then, the punching device 700 is operated as described above, and the feed roller 410 of the cutting device 400 is moved after the transfer of the film (2) formed through the hole by the motor 420 by a set distance Stops. Then, the cutting knife 432 of the cutting member 430 is cut downward while cutting the conveyed film (2). At this time, it is natural that the film 2 conveyed and discharged through the feed roller 410 is already placed on the mounting plate 550 of the feed device 500 before the cutting knife 432 is cut. Subsequently, when the film 2 is cut off, the adsorption port 560 provided between the mounting plates 550 of the conveying device 500 adsorbs the lower surface of the film 2 through air, and soon the conveying device ( The motor 540 of the 500 is operated to rotate the rotation shaft 530 so that the transport frame 520 is transported along the transport rail 510 to stop at the set position.

When the transfer device 500 transfers the film 2 in this manner, the attachment device 600 provided on the upper side receives the film 2 and attaches it to the open type box 1 transferred by the transfer means 100. Done. That is, as shown in "a" and "b" of FIG. 13, when the transfer device 500 transfers the film 2 and is positioned below the attachment device 600, the suction port of the transfer device 500 is further increased. Abnormal air is not adsorbed, and the adsorption plate 650 of the attachment device 600 immediately adsorbs the upper surface of both ends through the air, thereby separating it from the transport device 500. Then, the transfer apparatus 500 returns to the original position, that is, toward the cutting apparatus 400, by the operation of the motor 540 to prepare for the next transfer.

After the transfer device 500 returns as described above, the attachment device 600, that is, the attachment frame 610 is downwardly operated due to the operation of the operation cylinder 620 as shown in “I”, and the suction plate 650. The film (2) adsorbed on is immediately attached to the opening of the open box (1) located on the lower side, and stops the adsorption of air and then returns to the operation of the operating cylinder (620) to return to the minimum standby state. At this time, since the adsorption plate 650 has an elastic force due to the interposed spring 660, the adsorption plate 650 will attach the film while absorbing the impact of contact with the upper surface of the open box 1 during attachment. Of course, it is natural that the adhesive parts provided at both ends of the film 2 are located at the lower side so that they can be directly attached to the box 1. In this way, when the attachment device 600 attaches the film 2 to the open box 1, the stopper (not shown here) of the conveying means 100 is lowered and the rotating roller is rotated at the same time so that the film 2 is attached. The open box 1 is transported and discharged, and the user collects the packed box 1 and supplies a new box again.

Therefore, according to the automatic film attaching machine 10 of the open type box of the present invention, the cutting device 400 automatically cuts the film mounted on the mounting roller 300 during the packaging operation of various agricultural products using the open type box 1. And the transfer device 500 transfers the cut film 2, and the attachment process is partitioned step by step in such a manner that the attachment device 600 attaches the transferred film, and the film cut to the size of the open box 1 at the same time. (2) is attached to the packaging failure rate is significantly lower, in particular, the punching device 700 is also formed through holes in the film (2), so that the labor costs can be reduced by full automation, and the productivity is increased so that the farm income is greatly improved There is an advantage.
