Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a method for producing a seaweed packaging bag and an apparatus therefor.

“Prior Art” Conventionally, as shown in FIG.
The product was wrapped in a heavy-packed triangular bag, the opening was folded back and closed, and the closed part was fixed with an adhesive tape to give a wrapped seaweed product. However, the triangular bag is manufactured by hand, and even if it is manufactured by a machine, the inner and outer bags and the sandwiched seaweed are easily displaced from each other, and it is necessary to hold them so that the triangular rice ball is inserted into them. Therefore, there is a problem that it is not suitable for mass production in a short time because it requires skill and it is difficult to improve work efficiency.

[Problems to be Solved by the Invention] The present invention is suitable for short-time mass production of packaged seaweed rolls, without requiring skill, for a triangular seaweed roll packaging bag in which the inner and outer bags and the sandwiched seaweed rolls do not shift from each other. The idea is to get a seaweed wrapped bag.

"Means for Solving the Problems" The present invention relates to a first step of fitting a V-shaped inner bag to a V-shaped heat-resistant plate, a second step of wrapping the outer surface of the inner bag with seaweed, and an outer surface of the seaweed. The present invention is characterized by the third step of fitting the V-shaped outer bag and the fourth step of heating and welding the inner and outer bags along the opening edge of the inner and outer bags and then separating the inner and outer bags from the V-shaped heat-resistant plate. It is constructed by a method of manufacturing a seaweed packaging bag and its equipment.

[Operation] Accordingly, when the endless rotation chain is rotated, the V-shaped heat-resistant plate moves from the start end side to the end side of the upper transition portion, and passes through the V-shaped inner bag fitting device, so that the heat resistance is increased. The V-shaped inner bag is fitted to the plate, and further moved to wrap the outer surface of the inner bag with seaweed by the seaweed wrapping device. And in that state, the next V
The V-shaped outer bag is fitted to the outside of the seaweed by passing through the character-shaped outer bag fitting device. Thereafter, the inner and outer bags are heated and welded by the opening edges passing through the heat welding device, and the opening of the inner bag is not welded and sealed by the interposition of the heat-resistant plate. The inner and outer bags are separated from the heat-resistant plate and unloaded when the terminal portion of the above is bypassed downward. At the upper transition part, the inner and outer bags are pressed toward the heat-resistant plate by frictional resistance due to a slack prevention guide provided between the devices, and seaweed is slackened or dropped off from the heat-resistant plate by pressing the overlapping parts on both ends. There is nothing to do.

[Example] A pair of parallel endless rotary chains 8 and 8 are hung between the start and end sprockets 14 and 15 provided on the machine frame 7, and a support plate is provided on a connecting rod 16 that is installed on the chains 8 and 8 at equal intervals. 17, a metal flat plate 18 is detachably supported by screws 19 on the outer end of the support plate 17, one end of the flat plate 18 is formed in a V shape, and the tip thereof is the chain 8, The V-shaped heat-resistant plate 1 is formed in the rotation direction of 8. A device 9 for fitting the synthetic resin V-shaped inner bag 2 to the heat-resistant plate 1 from the start end side to the end side of the upper transition portion of the chains 8, 8 as described above, and the inner bag 2 is covered with seaweed 3. A device 10, a device 11 for fitting a synthetic resin V-shaped outer bag 4 to the same seaweed 3, and a device for heating and welding 6 the inner and outer bags 2, 4 to each other along the opening edge 5 of the inner and outer bags 2, 4. 12 are sequentially arranged. The inner and outer bags 2, 4 and the slack prevention guides 13, 1 between the devices 9, 10, 11, 12 due to the friction of the covered seaweed 3 are also provided.
3'and 13 are provided. The heat-resistant plate 1 is one in which the inner and outer bags 2, 4 are pressure-bonded to the upper and lower surfaces with heating tools 20, 20, and must not be burnt or burned by heating (for example, thick paper) (FIG. 4). The guide 13 'is provided between the seaweed covering device 10 and the outer bag fitting device 11 so as to cover the seaweed 3
The upper end of the overlapped portion 3 '(FIG. 3) at both ends of the inner bag 2 and the outer bag 4 may be in contact with the other guides 13. Then, the terminal sprocket 15 is driven to rotate the chains 8, 8 in the direction of the arrow a, and the inner bag fitting device 9 is first used to cover the V-shaped heat-resistant plate 1 with the inner bag 2 and then the covering. The inner bag 2 is wrapped with seaweed 3 by the device 10, and the outer bag 4 is capped on it by the device 11, and then the upper and lower heating tools 20, 20 of the welding device 12 are directed to the upper and lower surfaces of the heat-resistant plate 1. By heat-bonding 6 between the two bags 2 and 4 along the opening edge 5 of the inner and outer bags 2 and 4 by crimping, then when the terminal sprocket 15 is detoured downward, The inner and outer bags 2 and 4 can be dropped and separated to produce a seaweed wrapped bag 21 (FIG. 5). After that, since the opening edge 5 of the packaging bag 21 is the welded portion 6, the inner and outer bags 2,
4 is opened at the same time to accommodate the triangular rice ball 22 in the inner bag 2,
The opening edge 5 is folded back as shown in FIG.
The product is closed at 3 to form a product. The reference numeral 24 in FIG. 7 denotes a supply box for the inner bag 2, 25 denotes a suction cup for the inner bag 2,
26 is an intermittent rotation shaft of the suction cup 25, 27 is an intermittent lift suction cup for opening the inner bag 2, 28 is a supply box for the seaweed 3, 29 is an intermittent lift suction cup for the seaweed 3, 30 is an opening / closing plate for laver packaging, Reference numeral 31 is a supply box for the outer bag 4, 32 is a suction cup of the outer bag 4, 33 is an intermittent rotation shaft of the suction cup 32, 34 is an intermittent lifting elevator for opening of the outer bag 4, and 35 is a heating tool 20, 20. Intermittent lifting arm, 36 motor, 37 drive sprocket, 38 drive chain,
In FIG. 5, 39 and 40 are perforations for tearing.

"Effect" Since the present invention uses the above-described method and apparatus, not only the inner and outer bags 2 and 4 and the seaweed 3 of the triangular seaweed-wrapping bag 21 are not likely to be displaced, but also skilled in the art, it is possible to manufacture the seaweed quickly and easily. It is possible to obtain a packaging bag capable of mass-producing packaged seaweed rolls in a short time.
