The present invention relates to be used for to the film that forms packaging body carry out ultrasonic wave coating as this packaging body Kaifeng with the super sonic cartridge of being with (ホ one Application) with have the ultrasonic wave coating work assembly of this cartridge.
To be with deposited pass to fasten, because to make but the requirement of strength when Kaifeng is arranged has been used the band also thicker than this film with the film same material in film.
Packaging body, bologna sausage for example, have band along the packaging body length direction roughly total length the rip cutting band and be located at circumferential horizontal proper band (the normal strap that simply cries).Under the proper band situation of horizontal stroke, as shown in Figure 3, strap 51 is along the end that circumferentially is mounted on packaging bodies 50 such as bologna sausage.Strap 51 circumferentially extends along packaging body 50, and is deposited at the film of specific potted line 52 partial sum packaging bodies 50.Thereby when Kaifeng, the non-deposited part of strap 51 is in most cases being pinched its end along direction of arrow pull-up with hand, because powerful pull-up, the film of packaging body 50 is along circumferentially breaking, breaking a seal.The form of this potted line 52 can have various forms of implementation, and for example image pattern 4 (A), (B) are like that.
The rip cutting band, when band-like film is formed for the tubular of filling content, can be along the deposited band of tubular film that moves, obtain stable deposited; But belt must be along the total length of bologna sausage, and is not economic.About this point, horizontal proper band, strap is short and economical, but when deposited band must with the same moved further of film, it is complicated that its mechanism becomes.
On the other hand, for will variety of way being arranged with deposited (sealing) in aspect the heating of film, for example known have high frequency sealing, a ultrasonic sealing.For guaranteeing that band is deposited with sufficient intensity to film, will be with to the film pressurized by the wire sealing projecting strip part of being located at deposition apparatus, form potted line as Fig. 3, Fig. 4, this sealing projecting strip part is hermetically-sealed construction.In the high frequency sealing, cause electro spark easily; Harm for avoiding being caused by this electro spark has formed restriction to the Seal Design shape, causes difficulty to design.Therefore, do not exist the ultrasonic sealing of so-called electro spark problem extensively to be carried out.
Ultrasonic sealing is held pressurization with the platform of the work that cooperatively interacts to film and strap clamp with the super sonic cartridge and is carried out.Textural at wrapping machine, cartridge is positioned at film one side, and promptly platform has been positioned at the side of being with into the packaging body outside.Such cartridge and platform illustrate such as the situation that just forms the such potted line of Fig. 3, promptly as shown in Figure 5.
In Fig. 5, cartridge 60 is a tabular surface below platform 61, establishes Long Circle sealing projecting strip part 61A on platform 61.At film 53 side polarity heads 60,, film 53 and strap 51 at cartridge 60 and 61 clampings of platform, to its pressurized, heated at strap 51 side trim platforms 61.Strap 51 is firmly deposited on film 53 with above-mentioned sealing projecting strip part 61A, forms potted line 52.
In existing structure, the sealing projecting strip part is located on the platform, owing to can believe like this, band firmly compresses and has sufficient intensity ground deposited on film.
But in this existing mode, belt is because by platform sealing band portion patterned heat, melt earlier and be easy to generate fragile position than film, when in the film walking or when being subjected to external force by band afterwards, be easy to generate pin hole etc., from the intensity of when Kaifeng band and may invade these aspects of bacterium to content and consider, often produce some unwished-for situations.
Because these facts, the object of the present invention is to provide and not produce pin hole etc. on the packaging body, be used for guaranteeing with cladding intensity ultrasonic wave coating cartridge and have the deposited work assembly of this cartridge.
Summary of the invention
Super sonic cartridge of the present invention is used for packing back Kaifeng with band to as the film of packing when deposited and the platform cooperating.
In this super sonic cartridge, the invention is characterized in that be connected on the flat-bed cartridge front end face, formation has at least 1 sealing projecting strip part that is used to form the prominent bar of potted line.The form of sealing projecting strip part for example can be straight line, curve, both make up etc., can freely select; Its line number can be wall scroll, also can be most.
As according to the present invention because the sealing projecting strip part of patterned heat is located on the cartridge that is positioned at film one side, film is than the first fusing of strap and deposited on strap.Thereby, can not form the fragile part that strap melts earlier, also can not form pin hole or the excessive attenuation of wall thickness.That is it is constant that, band can be kept former intensity.Even produce fragile slightly position on the film, depositedly on film, also can be compensated owing to be with.
Super sonic cartridge of the present invention and platform have constituted ultrasonic wave coating work assembly, and in this case, the top end face of flat-bed and cartridge butt can form tabular surface, also can form the annular knurl line on this top end face.
Owing to form the annular knurl line on platform, band does not produce mobile, can the changing of the relative positions with the relative position of film, and it is best deposited to obtain no wrinkle etc.Because this annular knurl line prevents changing of the relative positions effect, extensively evenly exist on tape, do not carry out patterned heat, can be as the sealing first fusion zone the bar of dashing forward.
In the present invention, on the platform, be preferably in, be provided for adsorbing the attraction mouth of retainer belt corresponding to the position outside the cartridge sealing projecting strip part formation field.Owing to attract a mouthful retainer belt with this, can further prevent really and film between produce the changing of the relative positions.
