Description

Product packaging device {APPARATUS FOR PACKAGING PRODUCT}

The present invention relates to a product packaging device that performs a series of processes for packaging a product having a patch shape with a synthetic resin wrapping paper.

Recently, a heating product having a patch form has been widely used, and conventionally a product containing a powder type heating agent has been used. .

In general, a product containing a heat generating agent generates heat while being oxidized by oxygen contained in the air. Therefore, in order to prevent arbitrary heat generation from the product, the product must be sealed and packaged in a packaging paper that does not allow air to pass through.

Conventionally, in order to seal and pack a product containing a heat generating agent in a packaging paper, the entrance of the synthetic resin packaging paper is widened, the product is put into the packaging paper, the air inside the packaging paper is bled, and the entrance of the product is sealed by a method such as heat sealing. in need.

In particular, in the past, the process of sealing the product in the wrapping paper was all done manually, and because the product is packaged manually, the sealing defect of the packaging paper occurs frequently, causing the product to heat up in the packaging paper, and the air inside the packaging paper is not sufficiently exhausted. Various problems are occurring, such as the problem that the product heats up inside the packaging and the problem that the fusion defect occurs during the thermal fusion process.

In addition, when the process of manually sealing the product inside the packaging paper is performed manually, the production cost of the product is greatly increased.

The lift unit 550 includes a corrugated picker 555 for sucking and fixing the upper surface opposite to the lower surface of the wrapping paper 4 . When a vacuum pressure is formed in the corrugated picker 555 , the end of the picker 555 is moved upward by the wrinkles of the picker 555 , and thereby the upper surface of the wrapping paper 4 is spaced apart from the lower surface of the wrapping paper 4 .

Referring to FIGS. 2 and 5 , the push unit 600 pushes the product 1 transferred by the transfer unit 300 into the wrapping paper 4 whose inlet is wide open by the wrapping paper inlet opening unit 500 . It acts as a pusher.

The push unit 600 may be used with a variety of exercise devices that reciprocate in a straight line to push the product 1 disposed on the transfer unit 300 into the wrapping paper 4 . In particular, the push unit 600 may be disposed on the upper portion of the transfer unit 300 to prevent an increase in the volume of the equipment and may be linearly reciprocated.

Referring back to FIG. 5 , when the push unit 600 and the inlet of the wrapping paper 4 are arranged close, the product 1 moved by the push unit 600 can be safely inserted into the inlet of the wrapping paper 4 , but , when the entrance of the transfer unit 300 and the wrapping paper 4 is far apart, the movement path of the product 1 is deviated from the designated path while the product 1 is being transferred by the push unit 600, and this causes the product 1 ) may not be accurately introduced into the inside of the wrapping paper (4).

On the other hand, even if the lower surface and the upper surface of the wrapping paper 4 are spaced apart by the wrapping paper inlet opening unit 500 , the left and right sides of the wrapping paper 4 are low in height, so that the product 1 may be caught in the wrapping paper 4 .

In order to prevent this, the guide unit 700 is disposed between the push unit 600 and the opening opening unit 500 of the wrapping paper.

Figure 6 is a plan view showing the operation of the guide unit shown in Figures 2 and 5.

5 and 6, the guide unit 700 allows the product 1 to easily and quickly flow into the inside of the wrapping paper 4 and at the same time spread both ends of the wrapping paper 4 and both ends of the wrapping paper 4 Increase the height of the product (1) to be inserted into the inside of the wrapping paper (4) without being caught on the wrapping paper (4).

The guide unit 700 includes a first guide unit 710 , a second guide unit 720 , and a rotation unit 730 .

The first guide unit 710 has a concave groove guiding one side of the product 1 is formed, and the second guide unit 720 has a concave groove guiding the other side opposite to one side of the product 1 . is formed The rotation unit 730 is respectively coupled to the first and second guide units 710 and 720 to rotate the first and second guide units 710 and 720 in clockwise and counterclockwise directions, respectively.

At this time, the first and second guide units 710 and 720 are disposed on the outside of the wrapping paper 4 before being rotated. It is placed in a position where it hangs on both ends of the.

The first and second guide units 710 and 720 may be formed in a shape in which the height of the groove is high in the portion adjacent to the transfer unit 300 , and the height of the groove is formed to be low as it approaches the wrapping paper 4 .

FIG. 7 is a cross-sectional view taken along line IV-IV' shown in FIG. 2 .

2 and 5 , when the product 1 is accommodated in the wrapping paper 4 , the wrapping paper 4 in which the product 1 is accommodated is transferred to the wrapping paper opening unit 500 by the wrapping paper transfer unit 900 . ) is transferred to the sealing unit 800 disposed next to.
