Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powder continuous filling cylindrical bag making device for filling powder or fine powder into a cylindrical bag and making bags continuously. The reason for this is that when the cylindrical bag is moved downward by the required length by the horizontal heat sealing means, the powder rises inside the cylindrical bag and the contact between the cylindrical bag and the cylindrical wall. In addition to preventing the powder from entering the space between the parts and allowing the powder to be transferred in a stable state, it also prevents the powder from seizing on the outer circumferential surface of the cylindrical wall and the inner surface of the bag, and prevents the powder from entering the lateral seal area. Make sure that no dirt gets in there and that you get a clean seal.

The applicant previously developed a cylindrical bag-making device for continuously filling powders and granules (Japanese Patent Publication No. 715/1983), but this device was not equipped with a weighing machine when filling and packaging powders and granules. The filling is received by a temporary stop suppressing member provided between the vertical heat sealing member and the horizontal heat sealing member, and then the temporary stopping suppressing member is released to allow the filling to fall downward again. At the same time, the horizontal heat-sealing member located below presses and clamps the cylindrical bag from both sides at a predetermined position and transfers the cylindrical bag downward by a required length (one bag) while heat-sealing the bag. It opens again and rises by a predetermined amount it to prepare for the next operation. Therefore, in the above device, when the filling material caught by the temporary stop suppressing member, especially in the case of powder, is dropped again by the release of the member, the material is lifted into a stable state within the cylindrical bag. Instead, the powder that flies up gets into the space between the cylindrical wall and the cylindrical bag, and the heat burns it onto the outer circumferential surface of the cylindrical wall or the inner circumferential surface of the cylindrical bag, interfering with work. At the same time, it had the disadvantage that it could get into the side sealing area, making it impossible to seal reliably and cleanly.

The present invention provides a temporary stop press heat sealing member for temporarily stopping the powder directly below the cylindrical wall, and a synchronous press release member that synchronously interlocks with the temporary stop suppressing member at the lower end of the cylindrical wall. By providing it at the top, it prevents a predetermined amount of powder to be packaged from flying up and entering between the cylindrical wall and the cylindrical bag, and allows the powder to be transferred in a stable state. This eliminates the drawbacks of the prior art by preventing powder from seizing on the outer circumferential surface of the cylindrical wall and the inner circumferential surface of the cylindrical bag, as well as preventing powder from entering the lateral seal portion.

Hereinafter, an embodiment of the present invention will be explained in detail with reference to FIGS. 1 to 4.

Reference numeral 1 denotes a band made of plastic film, paper, etc., which is wound and rotatably disposed as appropriate;
In the direction of arrow It gradually forms a cylindrical shape and travels through it. In this gap 7, both side edges of the strip 1 are superimposed on each other, so that when it leaves this gap 7, a complete cylindrical shape is formed. At this time, in order to ensure that both side edge portions of the strip 1 that have passed through the gap 7 are always overlapped with uniform dimensions, the strip 1 is placed on the guide member 6.
A lead member 9 made of a relatively hard elastic material such as Teflon or the like is provided with its tip inserted and guided between both side edge portions of the lead member 9. Reference numeral 10 denotes a vertical heat-sealing member, which abuts against the overlapping portions 11 of both side edges of the cylindrical strip 1 and electrically heats it to “stick” this portion by heat-sealing.

A synchronous pressing and releasing member is provided which presses the inner circumferential surface of the cylindrical wall to the outer circumferential surface of the cylindrical wall and releases the synchronous press-release member, and the temporary suppressing heat sealing member is provided with a synchronous pressing and releasing member that presses the inner circumferential surface of the cylindrical wall to the outer circumferential surface of the cylindrical wall. The tube is designed to receive the filler while it is inside the body and to prevent part of the filler from entering between the cylindrical wall and the cylindrical bag, that is, it forms a two-stage restraining means. When the cylindrical bag is pulled out using the horizontal heat-sealing member, even if the filling material is powder or fine powder with a light specific gravity, it can be stably transferred downwards, so that the filling material can be transferred to the inner peripheral surface of the cylindrical bag. It is possible to perform the work at high speed without causing any trouble in the work due to burning or getting into the side sealing part, and the temporary stop suppressing member is used as a heat sealing member to receive the filling. By performing both the stop and the horizontal sealing of the cylindrical bag in this area, there is no possibility that the filler will enter the sealing area when finishing the sealing with the horizontal heat sealing member in the later stage, and the seal will be sealed. It has features such as being able to reliably make it beautiful.

Note that the horizontal type seal member in this embodiment may be a cooling seal member, and the heat-sealed portion may be suppressed and cooled with the temporary stop suppressing heat seal member to further enhance the sealing effect. When the overlapping portions of the sheets are in the shape of palms, the vertical heat sealing means may be composed of a pair of well-known clamping rolls.
