Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a continuous stacking bag manufacturing apparatus for manufacturing a sealing bag, which is used by sealing it after loading a medicine such as a small-sized medicine bag and the like, from a plastic film material.

[0002]

[Prior Art]

 Conventionally, the number of bags used for sealing is one, and an adhesive is applied to the sealing portion, which is a manufacturing method in which a release paper is attached to protect the adhesive.

[0003]

[Problems to be solved by the device]

 The present invention eliminates the release paper attached to the adhesive part of the conventional adhesive-coated envelope bag, and makes it a plurality of envelope bags that are continuously connected.When used, it is cut and separated to create an envelope bag. The present invention intends to provide a continuous stacking bag manufacturing apparatus for use.

[0004]

[Means for solving the problem]

 In order to achieve the above object, as illustrated in FIG. 1, the heat-sealing machine 3 is used so that the bag-shaped plastic film material is rewound and fed into the apparatus according to the present invention so that both sides of the material are at the bottom of the bag. The edges of the bag are formed from both sides of the material to the center of the material, leaving the margin of the adhesive seal part, and then the center of the margin is divided to create the opening of the bag. Fold one side of the plastic film in the margin to form the adhesive seal.

A pressure-sensitive adhesive coater 8 applies a pressure-sensitive adhesive to the folded-back portion of the plastic film in the opening or the other side thereof to form a pressure-sensitive adhesive seal portion.

Perforations are inserted into the heat-sealed portion of the plastic film material by the perforation machine 10 so that it can be separated from the perforations.

Every time the required number of plastic film materials is cut, the cutting machines 11 and 12 cut the heat-sealed portion and wind the plastic film material as a continuous sealing bag.

Markers 15 can be used to mark the required indication on the plastic film material.

In order to facilitate tearing and opening of the sealing bag, a notcher 18 that is provided with a notch in the heat seal portion can be provided.

[0010]

[Action]

 By using the continuous wrapping bag manufacturing device according to the present invention, the continuous wrapping bag can be manufactured from the inflation or uniaxially stretched plastic film material.

The continuous sealing bag can be easily cut and separated from the perforations to be used as an individual sealing bag.

The purpose of use becomes clear by marking the plastic film material.

By providing a notch in advance in the sealing bag, when the bag is opened after sealing, the notch portion serves as a tear mark and can be easily torn and opened from this portion.

[0014]

【Example】

 Embodiments will be described with reference to the drawings. FIG. 1 is a perspective view of a continuous stacking bag manufacturing apparatus according to the present invention. As an example, a coil of inflation plastic film having a thickness of 0.04 mm and a width of 170 mm is used as a material and sent out from a rewinding machine. The fed material is heat-sealed one after another by the heat sealer 3 with a length of 75 mm from both sides of the material and a heat-sealing interval of 65 mm.

The width of the central blank portion that is not heat-sealed is 20 mm, and the center line of the split cutter 4 is cut and divided in the longitudinal direction to form the opening of the bag.

One of the plastic films in the margin of the opening is pushed open on both sides by the folding mold 6, and the pushed plastic film is pushed by the pinch roll 7 to form a folded portion having a width of 10 mm.

The pressure-sensitive adhesive coater 8 applies the pressure-sensitive adhesive to the folded portion having a width of 10 mm, and the dryer 9 dries it.

A perforation is made over the entire width by the perforation machine 10 along the center line of the seal portion which is the boundary between the bags.

Since the plastic film material is divided into two at the center in the longitudinal direction, the plastic film material is wound by the winder 13 and the winder 14, respectively, cut by the necessary number of cutting machines 12 and 13, and divided. Make a double-sealed bag.

In the notcher 18, a notch is formed in the heat seal portion to indicate a tear position, and the tear is facilitated.

Markers 15 are used for marking as needed.

By cutting the heat-sealed portions one after another with the cutting machines 11 and 12 without using the sewing machine, it is possible to manufacture a singular sealed bag.

[0023]

Since the present invention is configured as described above, it has the following effects.

A sealing bag can be manufactured from an inflation or uniaxially stretched plastic film material.

The above-mentioned plastic film material has a property of being easily torn in the stretching axis direction. Since the opening of the sealing bag is formed in the stretch axis direction of the plastic film, it is easy to tear by hand from the notch along the opening, that is, in the stretch axis direction when opening for use after sealing.

Both edge portions of the plastic film material are the bottom portion of the sealing bag, and the margin portion that is the central opening portion is divided in the longitudinal direction into two upper and lower plastic films. It can be folded back and coated with an adhesive on this part for sealing.

It is possible to wind it up as a coil without using a release paper in the adhesive application portion. Can be separated from perforations when in use.

With the cutting machine, it is possible to manufacture the required number of continuous wrapping bags or a single wrapping bag.

In the device it is possible to mark the required display.

A notch that facilitates tearing can be provided in the direction of the stretching axis of the plastic film.
