DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple air-filled buffer bag, a buffer bag band, and an intermittent air injecting device. The present invention relates to a simple air-filled buffer bag, a buffer bag band, and an intermittent air injection device capable of preventing the deformation that occurs.

2. Description of the Related Art It has been proposed that a simple air-filled buffer bag in which air is sealed is inserted into a gap or the like when articles are stored in a box, thereby forming a buffer member. This simple air-filled buffer bag is made of paper, does not use harmful substances, is lightweight, easy to handle, and has attracted attention as a low-cost and safe buffer member.

Conventionally, in order to continuously manufacture a simple air-filled buffer bag, two paper strips are laminated or one paper strip is folded so as to provide a fold in the longitudinal direction. Using a paper belt-shaped body, a bag having an air inlet is bonded to form a plurality of bags to form a buffer bag, air is injected from the air inlet, and the air inlet is heated and sealed,
It has also been proposed to make a plurality of simple air-filled buffer bags by separating them.

As an air filling device used to fill air into the buffer bag, a nozzle is inserted from an air inlet of the buffer bag, air is injected, and the air inlet is heated and sealed. The air enclosing apparatus has two gripping members for fixing and supporting the buffer bag when injecting air and performing heat sealing. Conventionally, however, the distance between the two gripping members has not been changed. Therefore, near the air inlet of the buffer bag
The nozzle was inserted and air was injected, causing it to expand and deform. If the next heat sealing treatment is performed while expanding and deforming, wrinkles are likely to occur and heat sealing becomes insufficient, resulting in a problem such as a defective simple air-filled buffer bag.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described. One embodiment of the simple air-filled buffer bag, buffer bag band, and intermittent air injection device of the present invention will be described with reference to FIGS. Drawing 1 is an explanatory view of an intermittent air injection device of an example. Drawing 2 is an explanatory view of a buffer bag band and an intermittent air injection device in an example.

An embodiment will be described. As shown in FIG. 1, the intermittent air injection device according to the present embodiment includes a pair of grip members 1a, 1
b, the gripping member control mechanism 2, the nozzle 3, the position detection sensor 4, the heat sealing member 5, the moving mechanism 6, the separating mechanism 7, the guide member 8, and the roll supporting member 9. The air is intermittently injected into the air inlet 11 of the buffer bag body 10.

The gripping members 1a and 1b are fixedly supported by gripping the gripping edge 14 of the buffer bag body 10 during air injection and heat sealing. The gripping member operating mechanism 2 operates the pair of gripping members 1a and 1b in directions away from each other at the time of air injection and heat sealing to apply tension to the buffer bag 10 between the gripping members 1a and 1b. The nozzle 3 is inserted into the air injection port 11 of the buffer bag 10 and injects air. The position detection sensor 4 detects a position mark 12 indicating the air inlet 11. The heat sealing member 5 includes a buffer bag band 10.
Is heated and sealed. The moving mechanism 6 moves the buffer bag body 10 from the position of the roll support member 9 to the positions of the nozzle 3, the heat sealing member 5, and the separation mechanism 7. The separating mechanism 7 separates the buffer bag band 10 into a simple air-filled bag 20. The guide member 8 is composed of, for example, a guide bracket, and when the buffer bag body 10 is moved,
4 is inserted between the unbonded laminated portions and guided. The roll support member 9 mounts a roll-shaped wound body of the buffer bag band 10. The intermittent air injection device according to the present embodiment applies tension to the buffer bag band 10 at the time of heat sealing, so that the vicinity of the air injection port 11 can be prevented from being expanded and deformed,
It is possible to reduce the amount of the simple air-filled buffer bag 20 that is defective.

The buffer bag strip 10 used in the present embodiment has an air inlet 11, a position mark 12, an adhesive portion 13, and a gripping edge 14, and is a roll wound body wound in a roll shape. And attached to the roll support member 9 of the air injection device,
Pulled out during air injection. The air inlet 11 is provided with the nozzle 3

One paper band is folded so as to provide a fold in the longitudinal direction, and the periphery of the portion serving as the simple air-filled buffer bag 20 other than the air inlet 11 is adhered. It is also possible to laminate two paper strips and adhere the periphery other than the air inlet 11. The gripping edge portion 14 is an edge portion on the side of the intermittent air injection device on the side of the buffer bag band body 10, and is gripped by the gripping member 1,
The movement of the buffer bag strip 10 during air injection and heat sealing is prevented. Since one or two paper strips are laminated and have a non-adhered portion, the guide member 8 and the nozzle 3 of the air injection device can be inserted therebetween.

An example of air injection and heat sealing in the intermittent air injection device of this embodiment will be described. 1) When the buffer bag 10 moves, the moving mechanism 6 pulls out the buffer bag 10 from the roll-shaped wound body attached to the roll support member 9. The guide member 8 guides the buffer bag body 10. The position detection sensor 4 detects the position mark 1 on the buffer bag band 10.
2, the movement by the movement mechanism 6 is stopped at the time of air injection and at the time of heat sealing, and is intermittently performed. 2) At the time of air injection, the gripping members 1a and 1b
The nozzle 3 is inserted into the air inlet 11 of the buffer bag body 10 to inject air. By the gripping member control mechanism 2, two gripping members 1a,
1b in a direction to pull them apart from each other to apply tension. 3) When a predetermined amount of air is injected, the gripping member control mechanism 2
The heat sealing member 5 heat seals the air injection port 11 of the buffer bag body 10 while giving the tension due to. 4) The separating mechanism 7 cuts at a predetermined position on the buffer bag body 10. 5) Repeat the above 1) to 4). Thereby, the simple air-filled buffer bag 20 can be manufactured continuously.

The obtained simple air-filled buffer bag 20 is heat-sealed by injecting air into the inside, has an adhesive portion and a heat-sealed portion, and has an edge which is a laminated portion that is not bonded. Part.
