DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the entire operation of a hooded film expandable automatic packaging apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

15A to 15F are operational state diagrams of the automatic packaging apparatus for the hooded film expandable type according to the embodiment of the present invention.

15A shows a state in which the hood film H supplied from the supply unit 200 is transported to the article P side through the transport unit 300 and the adsorption unit 500 installed at the lower side is folded in an M- And the hood film H is moved to both sides of the hood film H to unfold the hood film H to supply the hood film H. Fig.

15A, a hood film H wound in a roll form on a feeder 200 is fed to the feed unit 300 side, and the hood film H fed to the feed unit 300 is fed to the feed unit 300, As shown in Fig.

The feeder 200 feeds the hood film H wound on the take-up roller 220 to the transfer unit 300 side by the rotation of the feed roller 230.

At this time, the feed roller 230 is moved by the operation of the feed control cylinder 241 in response to the amount of the hood film H wound on the take-up roller 220, So as to be always in close contact with each other.

The transfer unit 300 transfers the hood film H supplied from the supply unit 200 to the lower side on which the product P is placed.

At this time, the support roller 320 is moved to the conveying roller 310 side by the operation of the support cylinder 321, and the conveying motor 311 rotates the conveying roller 310, It is possible to transfer the hood film H supplied to the lower side of the article P to the article P placed on the lower side.

The hood film H supplied from the supply unit 200 and conveyed downward through the transfer unit 300 is conveyed to both sides of the hood film H by the adsorption unit 510 moved to both sides of the hood film H And is adsorbed.

15B is a diagram showing a state in which the adsorption unit 500 adsorbs both sides of the hood film H and is opened.

15B, the adsorption unit 500 is configured such that the fan 513 installed at the rear of the adsorption unit 510 sucks air on the adsorption unit 510 and adsorbs the hood film H by the air suction force So as to spread the hood film (H) in the form of a hood.

The suction unit 510 is installed on both sides of the hood film H so that the second drive gear 533a rotates as the second drive motor 533 operates and the other drive gear 533a And a second chain 533c connected to the second driven gear 533b and the second chain 533c provided at the end of the second drive gear 533a and the second driven gear 533b, So that the hood film H is unfolded.

At this time, the hood film H is fixedly supported by the film supporting portion 514, and can be stably deployed without being separated from the adsorption portion 510.

Due to such a configuration, the adsorption unit 510 is moved away from or close to each other in accordance with the size of the hood film H supplied by the operation of the first driving motor 524, and the size of the supplied hood film H So that the hood film H can be spread.

15C shows a state in which the support bar 613 of the expansion unit 600 is pulled into the hood film H and the contact roller 614a of the hitch 614 is pulled out of the support bar 613 from the outside of the hood film H, And the hood film (H) is supported.

Referring to FIG. 15C, the support bar 613 is drawn into the hood film H while the expansion unit 600 rises toward the extended hood film (H).

The contact roller 614a is moved to the side of the support bar 613 by the operation of the tightening cylinder 614c to support the outer side of the hood film H. [ (See Fig. 15)

At this time, the film supporting portion 514 which fixedly supports the hood film H releases the hood film H fixed and supported by the operation of the angle adjusting cylinder 515. [

15D shows a state in which the hood film H is brought into close contact with the lower side of the support bar 613 with the tight contact portion 614 supporting the hood film H and the fused portion 420 of the fusion bonding unit 400 is brought into contact with the hood film H, The upper portion of the hood film H is fused and the cut portion 430 cuts the fused upper portion of the hood film H. Fig.

15D, the hood film H supported between the support bar 613 and the contact roller 614a is closely contacted downward as the contact roller 614a closely attached to the support bar 613 rotates.

When the tightening is completed, the supporting frame 410 of the fused portion 420 provided at the upper portion is moved in a direction approaching each other to support the hood film H.

The fusing frame 421 of the fused portion 420 advances from both sides of the hood film H toward the hood film H to fuse the hood film H. [

After the fusion of the hood film (H) is completed, the upper part of the hood film (H) is cut while moving the cutting edge (431) of the cut part (430) in the longitudinal direction of the supplied hood film (H)

15E is a view showing a state in which the support frame 410 releases the hood film H after fusion and cutting of the hood film H are completed.

Referring to FIG. 15E, as the support frame 410 releases the hood film H, the hood film H is more closely attached to the expansion unit 600 side so that the entire side surface is closely contacted to the support bar 613 side And the upper portion is fused and unfolded in a clogged state.

15F is a view showing a state in which the hood film H is expanded by the expansion unit 600 and then moved toward the article P to complete the packaging of the article P. [

Referring to Fig. 15F, the hood film H is expanded more widely than the size of the article P by the expansion unit 600. Fig.

The hood film H in the expanded state is moved to the article P side by the lifting frame 630 to package the entire article P.

When the hood film H is covered with the entire article P, the supporting bar 613 of the expansion unit 600 is released from the hood film H covered by the article P, (P) side.

When the entire process for packing the goods is completed, the expansion unit is raised again to return to the initial position, and then the continuous operation of the article becomes possible by the above-described operation state.

As described above, in the hood film extended type automatic packaging apparatus according to an embodiment of the present invention, when the article is packed, the hood film continuously supplied in a folded state having both sides of 'M' shape is sucked by air suction, Thereby preventing the hood film from being damaged.

In addition, the hood film stretched over the expanded article is moved to the article side and is easily put on the article, and the hood film covering the entire article is shrunk again as the expansion unit is separated, so that the article can be firmly packed.
