Description

Half-cut connection packaging bag manufacturing unit and packaging device including the same {Half-cut connection packaging bag manufacturing unit and packaging device including the same}

The present invention relates to a half-cut connected packaging bag manufacturing unit and a packaging device including the same.

In general, a packaging bag is used to conveniently pack various types of products. Recently, with the increase in online shopping, there are many cases in which products are delivered in packaging bags.

In order to pack an article in a packing bag, the opening of the prepared packing bag is opened, the article is put into the packing bag, and the opened entrance is sealed.

When such a packaging process is performed manually, labor cost burden and time consumption are high, and productivity is lowered. So, recently, the packaging operation has been automated using a packaging device.

However, it is difficult to manufacture packaging bags supplied to such a packaging device in a form convenient for use, and it is also difficult to continuously supply packaging bags of sizes suitable for packaging items of various sizes.

Korea registered patent (10-2133231)

An object of the present invention is to provide a half-cut connected packaging bag manufacturing unit and a packaging device including the same, which can solve the above problems.

The half-cut connection packaging bag manufacturing unit for achieving the above object,

A supply unit for supplying a fabric for packaging composed of a lower surface and an upper surface overlapping the lower surface;

a recovery unit for collecting connected packaging bags in which individual packaging bags manufactured from the packaging fabric are continuously connected;

A cutting member forming a cutting line on the upper surface of the wrapping fabric and forming a cutting line on the lower surface to induce cutting;

a sealing unit attaching the upper and lower surfaces of the wrapping fabric to form a sealing line; and

It characterized in that it comprises a control unit for transmitting a control signal to the supply unit, the recovery unit, the cutting member and the sealing unit.

In addition, the above purpose,

A half-cut connection bag manufacturing unit for packaging; and

And a packaging unit disposed adjacent to the half-cut connected packaging bag manufacturing unit,

The packaging unit,

The half-cut connected packaging bag manufacturing unit receives a connected packaging bag in which individual packaging bags are continuously connected,

After the individual packaging bag is separated from the connected packaging bag by breaking the perforated line of the individual packaging bag in a state where the product is accommodated in the individual packaging bag,

It is achieved by a packaging device characterized in that for sealing the inlet of the individual packaging bag.

In the present invention, the cutting member of the half-cut connected packaging bag manufacturing unit is composed of a knife portion for cutting lines and a knife portion for cutting lines, and the knife portion for cutting lines forms a cutting line on the upper surface of the fabric for packaging while moving in the width direction of the fabric for packaging, The perforated-line knife portion follows the perforated-line knife portion to form a perforated line on the lower surface. Alternatively, in the present invention, the cutting member of the half-cut connected packaging bag manufacturing unit is composed of a laser unit for the cutting line and a laser unit for the perforation line, and the laser unit for the cutting line irradiates the upper part of the packaging fabric by irradiating a continuous wave laser while proceeding in the width direction of the packaging fabric. A cutting line is formed on the surface, and the laser part for the perforation line follows the laser part for the cutting line and irradiates the lower surface with a pulsed laser to form the perforation line. Here, the cutting line and the cutting line are positioned above and below the same line. In this way, individual packaging bags having a desired length or different lengths can be easily manufactured by adjusting the spacing between the cutting line (or perforation line) and another neighboring cutting line (or perforation line). In addition, individual packaging bags can be continuously manufactured and supplied to the packaging device.

In addition, if the cutting member of the half-cut connected packaging bag manufacturing unit is composed of a cutting line laser unit and a perforation laser unit instead of a cutting line knife unit and a perforation line knife unit, the cutting is performed according to the thickness of the packaging fabric or the wear of the knife of the cutting member. No need to replace parts.

The present invention has a vacuum suction unit to vacuum at least one of the upper and lower surfaces of the packaging fabric to increase the distance between the upper and lower surfaces. Due to this, it is possible to eliminate the possibility that a cutting line other than the perforated line is incorrectly formed on the lower surface by the cutting member.

In the present invention, the half-cut connected packaging bag production unit may be connected to the packaging unit to form a packaging device. Due to this, the packing unit receives the input of the size of the product to be packed, and the half-cut connected packing bag manufacturing unit can directly manufacture and supply the packing bag. Therefore, there is no hassle of replacing the packaging bag supplied according to the size of the product, and the packaging bag can be supplied in a desired size and packaged immediately, making the packaging operation convenient and reducing the packaging time.
