Description

{AUTOMATIC INSERTION MACHINE OF CARRYING BOX}

The present invention relates to a device for automatically inserting a plastic bag into a carrying box used for carrying fresh foods such as bean sprouts, and more particularly to a device for automatically inserting a plastic bag into a carrying box used for carrying fresh food, And an apparatus for automatically inserting a plastic bag into a box.

In general, the shipping box is used for storing and transporting agricultural products, aquatic products, and other items.

The carrying box may be configured to accommodate various items in the storage space by forming front, rear, left, and right side walls so that the entire storage space is used as one space, or the storage space And is used to store articles in each of the compartment spaces.

Particularly, when transporting small / medium sized goods at a long distance, they are transported in a standardized size, and these goods are put into a transport box, and then the transport boxes are transported in a container or transported by a freighter.

However, when packaging fresh food such as fruits, a transport box made of paper such as corrugated paper, a transport box made of a foamed material, or a transport box made of a plastic material is used.

Here, the carrying box of the paper material has a weak load bearing capacity, and the durability is further lowered by the moisture generated from the fresh food such as fruit, which has a problem that it is deformed or broken by itself when the fresh food is transported.

In addition, the box made of Styrofoam has a problem that bacteria such as fungi propagate due to moisture generated from fresh food, adversely affecting the quality of fresh food.

In addition, the plastic box has a problem that scratches are generated in the fresh food due to the friction generated between the fresh food and the fresh food during the transportation of the fresh food, thereby deteriorating the merchantability of the fresh food.

Recently, a vinyl plastic bag was installed between a fresh food and a transportation box to solve the above-mentioned problems. As a result, it is possible to prevent the direct contact between the fresh food and the carton box, thereby preventing the scratching of the fresh food and blocking the transfer of the moisture generated from the fresh food to the carton box.

However, packaging of vinyl plastic bags for transportation boxes is mostly manual, so the efficiency of work is greatly reduced. Due to the increase in labor costs, it is economically disadvantageous. In the case of short-term absence of workers, There is a problem that it is difficult to receive the initial order because it is difficult to predict.

In particular, in the case of manual work, a worker pulls out a vinyl plastic bag wrapped around a winding roll, cuts the bag at a predetermined length, and seals the lower end of the plastic bag one by one so that the plastic bag film can be individually arranged in units of one plastic bag It is also difficult to measure, and it takes a lot of time. When the cutting is completed, it is necessary to seal the lower end again to manufacture one unit plastic bag, seal the upper end of the plastic bag after putting the transportation box to be packed, There are too many and complicated processes and a lot of time consuming, and there is also a problem that workers must be arranged for each process.

Korean Patent No. 10-1120102 (published on Mar. 15, 2012) Korean Patent No. 10-1197418 (Announcement of Nov. 15, 2012) Korean Patent Publication No. 10-2016-0101776 (published on Aug. 26, 2016) Korean Patent No. 10-1419521 (published on July 15, 2014)

Accordingly, it is an object of the present invention to provide a method of automatically inserting a plastic bag into a carrying box, which can be automatically placed in a storage space of a carrying box for storing fresh foods such as bean sprouts, Device.

According to an aspect of the present invention, there is provided a wrapping paper guide unit for feeding a two-ply wrapping paper wound around a roll through a feed roller, And a first side joint portion and a second side joint portion of the two-ply wrapper passed through the packaging paper folding plate. Folded wrapping paper raised by the longitudinal moving unit after passing through the wrapping paper folding plate is sealed, and a cutting process is performed to cut the two- And a first fold and a second fold of the two-ply wrapped paper raised by the longitudinal movement unit are held on both sides of the two-ply wrapping paper, A lateral direction moving unit for horizontally moving the two-ply wrapping paper so that the two-ply wrapping paper is positioned on the same line as the transporting box with respect to the direction of the transporting box, and opening the two-ply wrapping paper so that the two- The two-ply wrapping paper is inserted into the upper part of the two-ply wrapping paper through the first descent so that the two-ply wrapping paper moved in the same line as the carry box by the transverse moving unit is held in the opened state, And a plastic bag insertion unit for bringing the upper portion of the two-ply wrapping paper into close contact with the upper outer surface of the transport box through a second lowering so as to be engaged with the transporting box.

According to the present invention, by arranging a plastic bag that is provided between a packaging box and a fresh food through an automatic machine and protects the fresh food and the packaging box, the work speed can be increased and the labor cost can be saved.

In addition, since the present invention uses physical means for opening the upper side of the plastic bag instead of injecting air, the occurrence of defective rate is reduced and environmental pollution at the work site is reduced.

In addition, according to the present invention, when the end of the wrapping paper composed of two layers is sealed and then cut to a certain length, the receiving surface of the shipping box can be completely covered.

These interpolation pieces 645, 646, 647 and 648 may be constituted by a first interpolation piece 645, a second interpolation piece 646, a third interpolation piece 647 and a fourth interpolation piece 648.

Specifically, the first interpolation piece 645 is coupled to the first spiral worm 643 in a direction perpendicular to the first spiral worm 643 and moves toward the fourth driving motor 630 before the worm axis 641 is rotated, And moves away from the fourth drive motor 630 in accordance with the reverse rotation of the worm shaft 641.

The second interpolation piece 646 is positioned in the opposite direction to the first interpolation piece 645 with respect to the worm axis 641 and has one end meshed with the first spiral worm 643 in the vertical direction. And moves to move away from the fourth driving motor 630 in accordance with the reverse rotation of the worm shaft 641. [

The third interpolation piece 647 is positioned in the same direction as the first interpolation piece 645 with respect to the worm axis 641 and has one end meshed with the second threaded worm 644 in the vertical direction. And moves to move closer to the fourth drive motor 630 in accordance with the reverse rotation of the worm shaft 641. [ In other words, when the worm shaft 641 is rotated forward, the distance between the third interpolation piece 647 and the first interpolation piece 645 is increased, so that the inner width of the plastic bag fitting portion 640 is widened. Further, when the worm shaft 641 rotates in the reverse direction, the gap between the third interposing piece 647 and the first interposing piece 645 becomes narrow, so that the inner width of the plastic bag fitting portion 640 becomes narrow.

The fourth interpolating element 648 is positioned in the same direction as the second interpolating element 646 with respect to the worm axis 641 and positioned opposite to the third interpolating element 647 and centered on the worm axis 641, The worm shaft 641 is engaged with the second screw thread worm 644 in the vertical direction and moves away from the fourth drive motor 630 in accordance with the rotation of the worm shaft 641. In accordance with the reverse rotation of the worm shaft 641, 630 < / RTI > In other words, when the worm shaft 641 is rotated forward, the distance between the fourth interpolation piece 648 and the second interpolation piece 646 is increased, so that the inner width of the plastic bag fitting portion 640 is widened. Further, when the worm shaft 641 rotates in the reverse direction, the interval between the fourth interpolation piece 648 and the second interpolation piece 646 becomes narrow, so that the inner width of the plastic bag fitting portion 640 becomes narrow.
