The specific embodiment
The object of the invention is to, provide by the conveying mechanism at the conveying band body and shield is set and to adding mobile cross directional stretch method and the device that carries out rectification and improve the efficiency of heating surface of hot-air.
[embodiment]
Below, with reference to accompanying drawing preferred embodiment describing cross directional stretch method of the present invention and device.
For identical with conventional example or equal part, use same label to describe.
Among Fig. 1, shown in the label 10 is conveying mechanism, and this conveying mechanism 10 has a pair of clamping section 1 that broad ways M each other separates, and this each clamping section 1 consists of with elongate in shape.
In fact above-mentioned each clamping section 1 is kept by the holder 3 of elongate in shape, and, be provided be used to cover the 4 and second clamping section, the first clamping section cover 5 that covers above-mentioned clamping section 1 at upper surface 3a and the lower surface 3b of this holder 3 shown in Figure 3.
Therefore, above-mentioned conveying mechanism 10 comprises by each a pair of clamping section that forms 1, holder 3 and first, second clamping section cover 4,5, above-mentioned each clamping section 1 constitutes, can utilize via above-mentioned each holder 3 not shown guide rail etc. when advancing along a direction X, to change its width along above-mentioned width M, carry out the cross directional stretch of the shoestring such as film 20 of being controlled by each clamping section 1.
Below reaching above the above-mentioned conveying mechanism 10, relatively be provided with first, second nozzle body 11,12 at above-below direction each other, this first, second nozzle body 11,12 directions along above-mentioned width M form elongate in shape and along the flow direction of the above-mentioned shoestring 20 identical with the length direction of above-mentioned conveying mechanism 10 namely a direction X arrange intermittently.
Therefore, above-mentioned conveying mechanism 10 formations as described below: between above-mentioned first, second nozzle body 11,12 and can be along one side to X mobile continuously.
Constitute, from above-mentioned first, second nozzle body 11,12 with the pre-heated hot-air 13 and 14 that adds with respect to the mode of the face quadrature of shoestring 20 downwards and upwards ejection, and constitute, spray the downward hot-air 13 that adds downwards from the first nozzle ejiction opening 11a of the first nozzle body 11, from the second nozzle ejiction opening 12a of second nozzle body 12 will make progress add hot-air 14 respectively towards above-mentioned conveying mechanism 10 side sprays go out, namely towards above-mentioned shoestring 20 ejections.
Above-mentioned first, the second clamping section cover 4,5 first, the second bight 4a, 5a is provided with first, the second shield 30,31, with regard to each shield 30,31 plate face direction, towards with each first, the second clamping section cover 4, each outer surface 4b of 5, the direction of the face direction quadrature of 5b (namely, with respectively add hot-air 13,14 emission direction is parallel) arrange first, the second shield 30,31, each shield 30,31 towards vertical direction extension setting, and above-mentioned first, second nozzle ejiction opening 11a, 12a and each shield 30,31 front end 30a, clearance D between the 31a be set to shown in Figure 6 just when.
Secondly, the action of above-mentioned existing transversal stretching device described.
The clamping section 1 of the both sides of the above-mentioned conveying mechanism 10 of shoestring 20 usefulness that at first, for example will be made of the film of extruding from the mould of extruder is controlled and is carried along a direction.
When carrying above-mentioned shoestring 20, as shown in Figure 3, knock with respect to each clamping section 1 not direct collision of advancing with set first, second clamping section cover 4,5 from the hot-air 13,14 that adds of above-mentioned first, second nozzle body 11,12 first, second nozzle ejiction opening 11a, 12a ejection, but from not corresponding with this first, second clamping section cover 4,5 first, second nozzle ejiction opening 11a, 12a add hot-air 13,14 and upper surface 20a and the lower surface 20b of above-mentioned shoestring 20 collide.
In these cases, at present, with first, the second clamping section cover 4,5 knock add hot-air 13,14 along each clamping section cover 4,5 flow, from first, the second ejiction opening 11a, 12a adds hot-air 13 with respect to what shoestring 20 vertically sprayed, 14 movement disorder and bending, therefore, the efficiency of heating surface that shoestring 20 heats up is reduced, but according to the present invention, be formed at above-mentioned first, the second clamping section cover 4,5 the most inboard first, the second bight 4a, 5a, namely add hot-air 13 with vertical direction, the direction ground that 14 emission direction (vertically) is identical upwards reaches and is provided with first to downward-extension, the second shield 30,31, utilize above-mentioned first, the second shield 30,31 will be along each clamping section cover 4,5 flow add hot-air 13,14 and with shoestring 20 direct collisions add hot-air 13,14 separate.
Therefore, the hot-air 13,14 that adds that flows along above-mentioned each clamping section cover 4,5 is cut off by each shield 30,31, can not flow into the upper surface 20a of shoestring 20 and the heating surface that should heat of lower surface 20b, and from each nozzle ejiction opening 11a, 12a ejection add hot-air 13,14 upper surface 20a and lower surface 20b with respect to above-mentioned shoestring 20 jets with rectangular state, compare the efficiency of heating surface that can significantly improve at present for heating shoestring 20.
Fig. 5 represents to be provided with each above-mentioned shield 30, the present invention of 31 consists of and the relatively hot carry-over factor of each shield 30,31 existing formation is not set and the width position of shoestring 20 between relation.
Namely, among Fig. 5, in existing formation, to till the controlling the position and be 300mm of clamping section 1, the relatively hot carry-over factor fluctuates, therefore, behind cross directional stretch, the cut waste treatment of each 300mm of the both sides of shoestring 20, but during the present invention consists of, shown that the relatively hot carry-over factor is stable from the position part of controlling minimum (about 20mm) inboard of position P of distance shoestring 20 by above-mentioned each shield 30,31 above-mentioned effect, therefore, the yield rate of cross directional stretch is compared at present and is significantly improved.
Fig. 2 and each shield 30 shown in Figure 5,31 front end 30a, 31a and the clearance D between each nozzle ejiction opening 11a and the 12a as shown in Figure 6, are preferably 10mm～30mm aspect the relation of relatively hot carry-over factor.
In addition, consist of by each above-mentioned shield 30,31 installation, can with each clamping section cover 4,5 knock add hot-air 13,14 with separate with the hot-air 13,14 that adds that shoestring 20 knocks, in this situation, each shield 30,31 and each nozzle ejiction opening 11a, 12a between the less situation of above-mentioned clearance D under, the relatively hot carry-over factor increases, and can improve the efficiency of heating surface of shoestring 20.
For example February 25 in 1993, everyday " the heat transfer handbook " the 54th page of the association distribution of this machinery and 55 pages were disclosed for heet transfer rate, determine by the width B of each nozzle ejiction opening 11a, 12a with to the distance H of shoestring 20, these relations as shown in Figure 8, NUB is nusselt number, be worth highlyer, heet transfer rate is higher.
In addition, as shown in Figure 8, have the zone that heat transfer coefficient rises by the H/B of above-mentioned distance H and width B, the applicant determines the width B of nozzle ejiction opening 11a, 12a and with respect to the distance H of shoestring 20 in order to obtain this field.In real machine, adopt heat transfer coefficient height and the shoestring 20 can be because not adding the zone of the state that hot-air 13,14 hot blast touch.
Industrial applicibility
In cross directional stretch method of the present invention and the device, by at each clamping section cover each shield being set, can with each clamping section cover and the heating air separation of colliding with shoestring, can significantly improve the heat transference efficiency with respect to shoestring.
