Definitions
- the present invention relates to a filling and packaging machine that seals a packaged object such as a liquid, a powder, or a viscous substance by three- or four-sided sealing a packaging film that is continuously transported vertically and horizontally. is there.
- Background art such as a liquid, a powder, or a viscous substance
- packaging bags for filling and hermetically sealing objects to be packaged are generally made of synthetic resin films or aluminum foil.
- a filling and packaging machine for producing a packaging bag with a three-side seal will be described with reference to FIGS. 10 and 11.
- a holding frame 2 is provided on the side of a machine base 1 of a filling and wrapping machine, and a film web R on which a film F is wound in a roll shape is detachably held on the holding frame 2.
- a film guide mechanism 3 and a film reversing mechanism 4 are arranged on the upper part of the machine 1, and a vertical seal mechanism 5, a horizontal seal mechanism 6 and a cutter mechanism 7 are arranged on the front face of the machine 1 from above.
- the packaging film F is guided to the film folding mechanism 4 through the film guiding mechanism 3, and the film F is folded in two along the longitudinal direction by the film folding mechanism 4, and then the heated vertical seal is provided.
- the film F is fed out while sandwiching the film F by a pair of left and right vertical seal rolls 5 A provided in the mechanism 5, and the film F is formed into a cylindrical shape by heat sealing with the vertical scene roll 5 A. Then, the film F is laterally heat-sealed by a pair of left and right horizontal seal rolls 6 A provided on the heated horizontal seal mechanism 6, and the horizontal seal FS is formed.
- the filling nozzle 8A of the filling mechanism 8 fills the film F formed with the material W to be packaged, such as a liquid, with a force such as liquid, and then the film F is sent to the horizontal sealing roll 6 of the horizontal sealing mechanism 6 again.
- a continuous packaging bag P is formed by laterally sealing FS the film mouth side of the film F with A and sealing the article W to be packaged, and then the intermediate portion of the horizontal sealing FS portion of the continuous packaging bag P is formed. It is known that the packaging bags P are separated and sent out one by one by being cut by a cutter mechanism 7.
- the horizontal sealing roll 6A of the first horizontal sealing mechanism 6 and the horizontal sealing roll 6A of the second horizontal sealing mechanism 6 are vertically arranged along the longitudinal direction of the film F. Two pairs are provided, and the packaged object W filled by the filling nozzle 8A of the filling mechanism 8 is sandwiched in the film F which is sent out while being formed into a cylindrical shape by the vertical sealing mechanism 5. After performing horizontal sealing S by heat sealing with a pair of horizontal sealing rolls 6 A provided in the first horizontal sealing mechanism 6 while attaching and pushing out, the horizontal sealing roll 6 of the first horizontal sealing mechanism 6 is successively formed.
- the horizontal seal hole FS of the second horizontal seal mechanism 6 is pressed again by the horizontal seal port 6A of the second horizontal seal mechanism 6 in the low-temperature superheated state or the normal temperature state to the horizontal seal FS part heat-sealed by A. To keep good There.
- the film F is fed out while being heat-sealed by the pair of vertical seal rolls 5A of the vertical seal mechanism 5, but the pair of vertical seal rolls provided in the vertical seal mechanism 5 is provided.
- the rotation speed of 5 A is low, the contact time between the vertical seal roll 5 A and the film F is long, so that the film F that is heated and melted by the heat of the vertical seal port 5 A
- the heat can be transferred to the hot-melt resin layer of the film F in an appropriate state and melted, and the appropriate heat seal can be applied to the vertical seal FH of the film F, but the transfer speed of the film F
- the transfer speed of the film F As the speed increases, the area of the film F that is heated by being sandwiched between the pair of the vertical seal rolls 5 A is abutted against the film F via the circular vertical seal port 5 A.
- the area to be heated is a narrow area, and as a result, the area to be heated is a narrow area. Due to lack of heat in each part of the part and the rear part in the rotation direction, the vertical seal FH contacting each part Poor heat sealing may occur.
- a preheating mechanism 9 is provided on the upper side of the vertical sealing mechanism 5, that is, between the film folding mechanism 4 and the vertical sealing mechanism 5 on the upstream side in the transport direction of the film F, The preheating mechanism 9 is disposed between the both end edges of the folded film F to preheat the ends of the two end edges of the film F, so that the film is heat-sealed while being pressed by the vertical sealing mechanism 5.
- a proposal has been made [for example, Japanese Patent Application Laid-Open Publication No. 2001-72019 (publication page 3-4, FIG. 1, FIG. 2)). See ].
- the preheating mechanism 9 including the conventional example including Japanese Patent Publication No. 2001-72019
- only the end of the folded film F is used as the preheating mechanism 9. Since the film F is heated by contact, the area of contact with the preheating mechanism 9 is small, so that the film F is partially heated, and the heat of the heated area Since the heat is propagated to the film F side and escapes, the preheating effect cannot be said to be good.
- the preheating temperature of the preheating mechanism 9 needs to be set higher. It is necessary to set the preheating temperature of the preheating mechanism 9 to be higher in order to obtain a good condition, and the fusion layer itself inside the film F may melt and damage the film itself. This point may be noticeable in the structure of Japanese Patent Application Laid-Open No. 2000-72019 in which a preheating mechanism is provided inside the folded film.
- a heater is built in the roller where the film F is fed out, and the film F is sent out while pinching or applying a predetermined tension by a heated roller, and heated by the preheating means consisting of rollers.
