Hereinafter, the operation and effect of the feed packaging device 10 according to an embodiment of the present invention having the above structure will be described.

The roll-shaped packaging bag is supplied seated in the rotary supply unit (110). By the rotation of the pair of feed rollers 114, the roll-shaped packaging bag is rotated and released. The packaging bag that is rotated and released from the rotation supply unit 110 is transferred to one side by the transfer roller 120.

The packaging bag to be transported to the conveying roller 120 is formed as a single packaging bag in the sheet forming unit 130. That is, as shown in FIGS. 2 and 3, the packaging bag supplied in the form of a roll is fused and sealed at one end by a sealing part 134 composed of a hot plate fusion machine, and a rear end on the sealing part 134 is cut ( 132) to form a single wrap bag.

At this time, the buffer supply unit 140 is provided between the rotary supply unit 110 and the sheet forming unit 130 to buffer the packaging bag supply speed and the working speed of the sheet forming unit 130 by the rotary supply unit 110. When the work of the sheet forming unit 130, the packaging bag is to stop a certain time, by the reciprocating roller 144 to press the packaging bag downward between the guide roller 142 to earn the working time of the sheet forming unit 130 It is possible to prevent the packaging bag from rolling. In addition, the front end of the packaging bag is gripped by the sealing unit 134, the tension can be maintained by the lower end of the reciprocating roller 144, it is possible to accurately cut without pushing the packaging bag.

In this way, it is possible to seal and cut the roll-type packaging bag and supply it as a single sheet, which can prevent supply shortage due to overlapping, which is a problem of the conventional packaging bag supplied in a single sheet, thereby improving productivity and reducing human rights costs. Has

The packaging bag supplied in a single sheet is delivered to the feed packaging unit 200 to feed the feed, and is sealed. In detail, as shown in FIG. 3, in the state in which the rear end is sealed by the sealing part 134, the packaging bag is vacuum-suppressed by one side and the other side by the vacuum part 212, and the opening is opened. When the opening of the packaging bag is opened, the mounting table 215 is rotated so that the holding member 216 formed at the end of the mounting table 215 is inserted into the opening, and is opened to hold the packaging bag.

Thereafter, the mounting table 215 is rotated to move the packaging bag to the feeding hole side of the feeder, and the packaging bag located at the feeding hole side is fixed by the packaging bag fixing part 220.

The packaging bag is inserted into the inside of the back clamp 222, the holding member 224 is unfolded by the holding cylinder 226 to press the packaging bag toward the back clamp 222, thereby fixing the packaging bag. In the above state, the feed of the feeder is supplied and filled in the packaging bag.

When the feed is completed in the packaging bag, the holding member 224 releases the fixing of the packaging bag by the operation of the holding cylinder 226, the packaging bag is transferred to the first transfer unit (310). The inlet opening sealing unit 230 is provided at the tip of the first transfer unit 310 to seal the inlet.

The packing bag filled with the feed is sealed is conveyed along the first transfer part 310, and is compressed by the first compression part 350 as shown in FIG. The first pressing part 350 is pressed by the pressing plate 352 by pressing the both sides of the packaging bag by the pressing member 354 made of a cylinder. At this time, the pressing plate 352 is accurately guided in a straight line by the second guide portion 355.

The packaging bag conveyed in the standing state by the first crimping unit 350 is pressed into an elliptical shape from a circular shape. The packaging bag is transported by the first transport unit 310 and then transferred to the second transport unit 320 by the redirection unit 330.

Looking at the operation of the turning unit 330 as shown in Figure 9 by pressing the lower end of the packaging bag transported in the standing state of the push block 332 by the operation of the cylinder, the upper end of the packaging bag contact bar 334 In contact with and conducts. At this time, the packaging bag may be conducted in a predetermined direction by the inclined surface 333 formed on the push block 332, and the inverted packaging bag is in a state in which it is transmitted to the second transfer part 320 while sliding from the inclined surface 333. Delivered.

Thereafter, the packaging bag is transferred to the conductive state by the second transfer part 320, and is compressed once more by the second pressing part 360.

Looking at the compression of the packaging bag by the second compression unit 360, as shown in Figure 10, the packaging bag conveyed by the second transfer unit 320 is made of a pressing conveyor provided on the upper portion of the second transfer unit 320 It is compressed by the second crimping unit 360. That is, the packaging bag is interposed between the second pressing part 360 and the second conveying part 320 and pressed.

The second crimping unit 360 may adjust the gap between the second conveying unit 320 by the spacing adjusting unit 370 to adjust the crimping degree of the packaging bag. That is, by coming out and extending from the screw guide 376 for rotating the screw 375, the distance between the second compression section 360 and the second transfer section 320 is adjusted.

As described above, the packaging bag transported by the first transporting unit 310 and the second transporting unit 320 is compressed twice so that a tighter compression is possible, and a larger amount of packaging bags can be loaded when the packaging is loaded by tight compression. It can improve space utilization.

As described above, the feed packaging device according to an embodiment of the present invention can be formed in a single sheet by supplying a packaging bag in the form of a roll and at the same time can reduce the manufacturing cost and eliminate the poor supply of feed, feed By pressing the packing bag filled with the can be packed in a certain size and shape, it is possible to improve the space utilization when loading.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.
