4 'is arranged horizontally, and when a lot of articles to be packaged, such as liquids, are put and a large horizontal swelling tubular material F1 is horizontally sealed at once, wrinkles may sometimes occur in the horizontal sealing portion. Causes poor horizontal sealing. In this case, since the packaged material such as the liquid in the tubular material F1 is heat-welded while being extruded within a very short time, the sealing portion is liable to be bitten, and the time for the horizontal sealing is not sufficient, and Shortages are more likely to occur. For this reason, it has been impossible to increase the speed and efficiency of the packaging operation.

Further, it is an object of the present invention to provide a vertical automatic packaging machine capable of increasing the speed of the horizontal seal without generating wrinkles in the horizontal seal portion and increasing the efficiency of the packaging operation.

している。In order to achieve the above-mentioned object, a vertical automatic packaging machine according to the first aspect of the present invention is characterized in that a long heat-sealing packaging film supplied in a longitudinal direction is formed on a forming chute. Leading and folding in two along the longitudinal direction to match both side edges, and the both side edges are vertically sealed by the vertical heat welding means for supplying in the longitudinal direction to obtain a tubular packaging film. Are horizontally sealed by the horizontal heat welding means arranged downstream of the vertical heat welding means to form a bottomed state, and the liquid or fluid material to be packaged in the tubular packaging film is placed in the molding chute. Sealed by the horizontal seal while filling via
A vertical automatic packaging machine for manufacturing a packaged product by cutting a horizontal seal portion of a packaging film by a cutting means, wherein the horizontal heat welding means has an axis vertical to the vertical seal portion side of the packaging film. The seal side is inclined in the range of 25 to 50 degrees so that the seal side is downward, and at least a pair of seal parts contact each other so that the seal starts from the vertical seal part side of the packaging film and ends at the opposite vertical seal side. It is characterized by comprising a pair of spirally formed heat welding rolls.

が確保される。Here, when the tube-shaped packaging film is sequentially pressed from the vertical seal portion side to the anti-vertical seal side, relative movement of the facing packaging film is allowed on the anti-vertical seal side, and finally, The folds are formed, and the pieces are smoothly adhered without generating wrinkles. Conversely, when the packing film is sequentially pressed from the side opposite the vertical seal to the vertical seal, the relative movement of the facing packaging films is restrained by the vertical seal, and wrinkles are concentrated on the vertical seal. Therefore, the axis of the horizontal heat welding roll is inclined such that the vertical seal side of the packaging film is up and the vertical seal side is down, and the sealing of the horizontal heat welding roll is started from the vertical seal side of the packaging film. Because it is formed in a spiral shape so that it ends on the side opposite to the vertical seal side, even if a large amount of articles to be packaged is inflated greatly, the tubular packaging film moves in the longitudinal direction and Lateral sealing is performed while being sequentially pressed toward the vertical sealing side, and a sufficient sealing time is secured.

選択される。More specifically, the width of the folded film is 70 mm and the length between the horizontal seals is 100.
mm, and the sealing length is 20 mm, the sealing time is 20/100. If the inclination angle is 30 degrees, 70
× TAN30 ° = 40.4, sealing time is 100
This is 60 / min, which is about three times the sealing time. Then, heat welding is performed smoothly and reliably without generating wrinkles. As described above, the sealing time is sufficiently secured by moving the packaging film in the longitudinal direction while the packaging film is being moved in the longitudinal direction, so that the packaging operation speed can be increased and the efficiency can be increased. The spiral inclination angle of 25 to 50 degrees of the seal portion of the lateral heat welding roll is appropriately selected depending on properties such as the viscosity of the article to be packaged.

2, and then folded in two along the longitudinal direction. Then, the two side edges of the folded packaging film F are joined, and then these two side edges are welded in the vertical direction. Means (a pair of heat sealing rolls for vertical sealing) 3, 3 to be vertically sealed to form a tube, and horizontal sealing means (a pair of heat welding rolls for horizontal sealing) on the downstream side are horizontally sealed. Put it on the bottom. The feeding of the packaging film F is performed by a pair of vertical sealing heat welding rolls 3 and 3 which are rotated via a drive shaft 31 by a dedicated servo motor (not shown). The liquid of the article to be packaged is constantly introduced from the liquid tank T into the bottomed tubular packaging film F1 via the chute 2 via the pipe 6 by the pump 5 forming a fixed amount supply device. Each time the horizontal sealing heat welding rolls 4 and 4 are operated, the tubular packaging film F1 is changed from the bottomed state to the sealed state, and is sequentially cut at the horizontal sealing portion of the packaging film F2 by the rotary cutting means 7. I'm going to go.

The bearing 45 is tilted by the bearing 45 and is rotatably supported by the bearing 45 via the drive shaft 46. Each drive shaft 46 is integrally protruded from an end face of each of the rolls 4, 4. The drive shaft 46 is driven by a motor M 1 via a reduction gear 51, a chain power transmission means 52, a gear power transmission means 53, and a universal joint 54. , 4 are rotationally driven so as to feed the packaging film F1 from top to bottom in synchronization with the feed speed of the vertical sealing rolls 3, 3. Roll for horizontal sealing 4,
4 are provided with a seal portion 41 which abuts each other at the time of the horizontal sealing operation. The seal portion 41 has the same angle as the inclination angle of the bearing 45 so that the center line A2 viewed from the front is horizontal in a roll mounted state. It is inclined on the contrary.

The sealing section 41 starts the sealing from the vertical sealing section side VS of the packaging film,
S is formed spirally so as to end with S
The first sealing work surface 41B forms an arc so as to be able to roll with the other side so that no excessive force is applied to the packaging film F1. A hole 41A into which a heating element is inserted is formed along the axis A1 at the center of the seal portion 41, and the seal working surface 41B is baked with silicon. The spiral inclination angle of the spiral seal portion 41 is appropriately determined together with the film feed speed according to the properties of the liquid of the packaged object.

It is inclined so as to be downward, and the sealing part of the horizontal heat welding roll is formed spirally so that the sealing starts from the vertical sealing part side of the packaging film and ends at the opposite vertical sealing side, so that one packaged product Even if a large amount of packaged material is inserted and swells greatly, the tube-shaped packaging film moves in the longitudinal direction while securing sufficient horizontal sealing time, and spirals from the vertical seal to the vertical seal. The object to be packaged such as liquid is pushed out by being sequentially pressed by the seal portion, so that heat welding can be performed smoothly and reliably without wrinkles. Thus, the packaging operation speed and efficiency can be increased by the horizontal sealing while moving the packaging film in the longitudinal direction.
