Description
Technical field
The present invention relates to a kind ofly be used to add heat-seal by the folding package that forms of the pack case method of the bottom of beverage packaging product particularly, according to this, being folded in the heating (activations) of the package bottom zone on the core of core wheel, is that the hot-air that adds that utilization is conducted through the air tap of a heated nozzle is realized; The invention still further relates to the device that is used to implement this method, according to this, this device has following part: a pulsed core wheel and a bottom shaped device that has the bottom forming convax mould, the heated nozzle that the air tap is arranged, and the device that is used for package bottom final molding and sealing.
Background technology
As is generally known, be used to seal method and apparatus by the folding package that forms of pack case of heat sealable coating, be diversified.In this respect, the sealing of package bottom all is just to realize on the so-called bottle placer of can factory in an orderly manner.There, single pack case is folded, and is pulled on the core, these cores all have a rectangle, with the corresponding cross section of package shape after this, they on pulsed core wheel equably according to radially arranging dispersedly.In order to make package bottom, then on the diverse location of pulsed core wheel at first to the bottom heating (activations) of the pack case that folded, pre-folded in addition utilize the final molding device to make it to obtain net shape at last, and is sealed the while then.Because used pack case all has been that heat sealable coating is crossed, for example scribble the very thin polyethylene of one deck, so the engagement medium that can add of the sealing of package bottom and realizing.
DE-AS 12 44 548 discloses a kind of device, be used to seal the packing container that is shaped to by the soft external member that stacks flatly, install according to this, utilizing a cylinder will have the heated nozzle that adds the hot-air tap before heating places on the heating location, in this, add hot-air be guided package bottom treat again it is turned back to initial position (resting position) subsequently in the closed area.Air tap herein all designs and produces as boring.
DE-AS 15 11 573 disclosed the another kind of locking device that is used for cardboard container, but this container has a kind of closure made from the thermoplasticity adhesives, on this device, heated nozzle equally alternately is in a resting position and an operating position, to reach equably the purpose for the treatment of the closed area that activates along with the pulse of core wheel bottom the package.According to this, the air tap all is designed to point-like or seam shape.In the case, in a definite time interval, heated nozzle is also stayed the pack case inside that is folded.
Know all that from DE 17 61 315 B2 the seam shape air tap in each angular region of heated nozzle is perpendicular to all that the seamed edge of heated nozzle arranged.
All known devices all have its intrinsic shortcoming, and the position that is heated that is exactly pack case all is heated inhomogeneously.In order not damage jointing material particularly not having to eliminate superheating phenomenon reliably under the bonding situation of aluminium foil, to reach the purpose of not damaging sealing function and trapping function.The result who causes thus is: in adding the direct discharge scope of hot-air, just on the opposite of air tap, no doubt can realize enough heating, but the heating in the zone between the air tap is inadequate at least in part.Above-mentioned shortcoming is certainly partly eliminated by the corresponding geometry of air tap, but must pay very big in the structural expense of heated nozzle for this reason.
Summary of the invention
Therefore the objective of the invention is to: so development and and then design that civilian head mentions and done the sort of method and apparatus that describes in detail in the above, make the closed area for the treatment of that keeps can heating equably under the simply constructed condition of used heated nozzle the package bottom folded up at the same time.In addition, also can realize to judge with optical means the hope of sealing quality.
According to the proposed method, above-mentioned purpose takes following measure to realize: in heating process, heated nozzle is directed each position to be sealed through pack case equably.Like this, just can realize the whole even heating that is heated the zone by optimum temperature reliably, this is to skim over the event of above-mentioned zone equably owing to add hot-air.
The device that proposes according to the present invention, above-mentioned purpose are achieved in that heated nozzle has a rectangular cross section that adapts with the shape of core basically, and have several casings that are connected with each other and a lid.Therefore, the device that the present invention proposes is structurally constructed simple especially, thereby also worthwhile especially on manufacturing cost.
According to another instruction of the present invention, heated nozzle can move on the bottom section of the pack case that is folded, and at its packing case and shift out and realize activation in the process of pack case of submerging.Geometry on heated nozzle is decided, bottom section can within the pack case and/or outside activated.According to this mode, can reach a kind of good especially activation, this is because activation is only finished event in the moment that core is taken turns before continuing to move to the distortion station on the one hand.
In another development of the present invention, done following setting:, additionally activate out the reference mark of two apart very small distances at least in the outside, zone that is activated that is used to form the package bottom.Two adjacent but activation reference mark at regular intervals are that the result who is caused is the quality of available optical means supervision sealing in not each other in the zone of sealing-in of package bottom.According to this, also monitoring Optical devices can be protruded into automation ground realization supervision in the package of opening.
If latter two reference mark in activation is separated from each other fully, proves that then activationary temperature is too low, thereby must heighten the bottom heating.If these two reference marks just in time flatly meet, represent that then activationary temperature is enough, has reached optimum operation conditions.If reference mark coincides fully, illustrate that then activationary temperature is too high, must turn down the bottom heating.In order to judge the reference mark that has been activated, can observe domain of dependence by the polaroid filter with on one side of aluminium coating of pack case.The zone that was activated can demonstrate the variation on the color under polaroid filter.In the case, reference mark for example can design conglobate reference point, but also can be designed to the reference bar with shape.
Activate preferentially to take turns and carry out when static at core.According to another development of the present invention, in order to improve impulse speed, heated nozzle also can be side by side along with the core revolution in activation.
In addition, following setting has been done in a favourable development of the present invention, is exactly that the air tap all is designed to hole and/or the line of rabbet joint.In this, the line of rabbet joint on each angular region of heated nozzle is preferably arranged perpendicularly with the seamed edge of heated nozzle.Because the heated nozzle that the present invention proposes is made up of a plurality of casings that are connected with each other, so the manufacturing of the discrete component of box-type just can be simple especially, this is to go up event because the line of rabbet joint can be arranged in " seam points " of adjacent casing.Therefore, simple especially according to the structure of heated nozzle of the present invention, thus its manufacturing cost also is worthwhile.
Description of drawings
With reference to the accompanying drawing that shows bright unique embodiment that chooses, the present invention is elaborated below.
In the accompanying drawing:
A kind of heated nozzle of the device that Fig. 1 the present invention proposes, to the side view of a longitudinal edge,
The heated nozzle that Fig. 2 is shown in Figure 1, to the side view of an end face,
Heated nozzle shown in Fig. 3 to 5 Fig. 1 and 2, to the following planar view of its casing,
The plane of Fig. 6 to 8 pair one that be cut open and the pack case that just is folded, was activated, activate best (Fig. 6), activated a little less than (Fig. 7) and activated (Fig. 8) by force.
The specific embodiment
Can find out immediately that from these figure the heated nozzle of the device that the present invention proposes is simple in structure.
Press the shown and institute's preferred embodiment at this point of accompanying drawing, heated nozzle 1 is made up of three casings, is respectively the casing of opening up and down, i.e. upper box 2, middle housing 3 and lower box 4.At this, lower box 4 downward (package inboard) is sealed with a lid 5.
Heated nozzle 1 is represented with two side view in Fig. 1 and 2, can find out the air tap particularly well at this, and they partly are designed to hole 6, partly are designed to the line of rabbet joint 7.
Fig. 3 to 5 expression in this, can be found out the heated nozzle project organization that has as the air tap of the line of rabbet joint 7 designs to the following planar view of each casing 2,3 and 4 especially.Can find out immediately, if the line of rabbet joint 7 is arranged on the edge of each casing 2,3 and 4, be can calculate very simply the expense on a kind of like this structure desired structure of heated nozzle.
Self-evident, each casing 2,3 and 4 external dimensions generally with a core that is pulled to bottle placer on, the interior cross section of the pack case that folded conforms to.In this, must so select its size, make between heated nozzle 1 and (not shown) pack case, to keep enough air gap, so that it is for example poly bonding or mobile to eliminate the material that sealability is arranged that has activated reliably.
According to the present invention, at this moment the heated nozzle to add the hot-air loading shown in the figure " sinks to " having in the zone of certain distance with core of pack case.Heated nozzle 1 skims over package zone to be activated in the turnover campaign that does not stop, thereby produces the district that is activated very uniformly, this can be continue after closed process set up out an optimum temperature.
Can find out immediately, air tap shown in the figure promptly hole 6 and the geometry of the line of rabbet joint 7 just select as example, also can heat bigger area equably by corresponding collocation layout, even can also produce different temperature provinces, if need these temperature provinces for closed process.
At last, in Fig. 6 to 8, show brightly, can utilize to be set in package bottom zone to be sealed outside even the reference mark on the package bottom, the quality that activates is carried out the optics supervision.This work also can automatically be carried out, and in this, a continuous regulating loop is modulated activationary temperature.In embodiment illustrated and that at this point preferably come out, as the reference sign, these reference points have very little distance each other, generate by activation in activation with circular reference point 8.Certainly, to any package specification, the distance between reference mark all must draw by rule of thumb, and this is because have several factors such as packaging material thickness, aluminum foil thickness, package size etc. all to work to this.Even be to judge to carry out optics in the packing container of opening above Optical devices are immersed in real work, but shown in Fig. 6 to 8, the bottom zone of pack case M is still cuts and directly draw the shop.
Optics to activationary temperature judges that step is as follows: two reference points 8 that have very little spacing ground to arrange each other in the pack case bottom zone, observe by a polaroid filter, and just can draw enlightenment about the sealing quality.If two reference points 8 just in time contact, show that then activationary temperature has obtained optimum setting, as shown in Figure 6.If two independent reference points 8 ' look as shown in Figure 7 illustrate that then activationary temperature is not enough, more definite theory, this just cries " activating deficiency ".
Arrow among the figure is pointed out the position that is not activated on the bottom zone to be sealed of the pack case M that cut.Fig. 8 represents unallowed " activating not enough ", in the case, and " the handing-over each other of two reference points 8.Can know at this and to find out: the face that (special opposite with " activating not enough " shown in Fig. 7) is activated is all crossed the permission boundary and is expanded according to dotted line or two-wire=superimposing thread in whole district.Under this state, the bottom zone that is activated also can tend to produce bubble.
