Definitions

  • the invention relates to a web heat treatment apparatus for heat-treating or drying a long or continuous web of woven or knitted textile fabric, non-woven fabric, film or the like.
  • a hot air blown from nozzles which are provided above and below the pair of upper and lower conveyer nets, strikes against the upper and lower surfaces of the web as to impart a rubbing or wrinkling effect onto the web that is loosened or in an overfeed state.
  • the heat treatment apparatus in the prior art has disadvantage in that, onto the web in an overfed state, only a rubbing effect in a lengthwise direction of the web may be imparted by hot air blasting from the nozzles; while a rubbing effect in a widthwise direction of the web is not achievable.
  • the invention-wise web heat treatment apparatus comprising: a pair of upper and lower conveyer nets adapted to run in a front-back-wise direction in a heat-treatment chamber; a plurality of upper nozzles provided above the pair of upper and lower conveyer nets to jet a hot blast against a web, which runs in a overfed state between the pair of upper and lower conveyer nets in the front-back-wise direction, from above; a plurality of lower nozzles provided below the pair of upper and lower conveyer nets to jet a hot blast against the web from under; upper blow-off ports on the upper nozzles for hot-air blasting, at least a part of which ports are dispsed obliquely relative to a widthwise direction of the web; and lower blow-off ports on the lower nozzles for hot air blasting, at least a part of which ports are disposed obliquely relative to the widthwise direction of the web and at same time relative to the upper blow-off ports.
  • the upper and lower blow-off ports on the nozzles are formed as slits extended along straight lines; the upper blow-off ports being disposed in parallel to one another; and the lower blow-off ports being disposed in parallel to one another and as to intersect the upper blow-off ports.
  • the invention-wise web heat treatment apparatus enables to impart, on a web by hot air blasting, a rubbing effect not only in the lengthwise direction of but also in the lengthwise direction of theweb. This is because the upper blow-off ports on the upper nozzles are disposed obliquely relative to widthwise direction of the web.
  • the web on heat treatment is prevented from meandering or width-wise winding. This is because the lower blow-off ports for hot air blasting on the lower nozzles are disposed obliquely relative to the upper blow-off ports for hot air blasting on the upper nozzles.
  • Fig. 1 is a longitudinal, cross sectional view as viewed from laterally of the heat treatment apparatus 10; and Fig.2 is a longitudinal, cross sectional view as viewed in rearward direction of the apparatus.
  • an entrance 14 is provided on a front surface of a heat insulating structure while an exit 16 is provided on a back surface of the heat insulating structure.
  • the web W is conveyed into a heat-treatment chamber 12 from the entrance 14, is subjected to heat treatment and then, after completing the treatment, conveyed out from the exit 16.
  • a plurality of upper nozzles 18 are arranged above a passage of conveying the web W within the heat-treatment chamber 12 and a plurality of lower nozzles 20 are arranged below the conveyance passage.
  • a pair of upper and lower web-spreading nozzles 50, 52 are provided near the exit 16. The construction of these upper and lower nozzles 18, 20 and upper and lower web-spreading nozzles 50, 52 will be described later in detail.
  • An upper endless conveyer net 22 for conveying the web W runs below the upper nozzles 18 in a front-to-back direction; and a lower endless conveyer net 24 runs above the lower nozzles 20 also in the front-to-back direction in a similar manner.
  • the web W runs, in a length-wisely loosened or overfed state, between the upper conveyer net 22 and the lower conveyer net 24.
  • the upper nozzles 18 and the lower nozzles 20 are disposed as divided into a first block and a second block in order from the entrance 14, at inside of the heat-treatment chamber 12.
  • the first block with the upper and lower nozzles 18, 20 are disposed near the entrance 14.
  • Fig. 2 shows a right-left-wise cross section of the heat-treatment chamber 12 as being crossed at the first block.
  • a stream-splitting duct 26 for vertically splitting a stream of hot air.
  • An upper duct 28 is connected to an upper portion of the stream-splitting duct 26 by joining in a right-to-left direction of the heat-treatment chamber 12; and a lower duct 30 is connected to a lower portion of the stream-splitting duct 26 also by joining in the right-to-left direction.
  • Top surface of the upper duct 28 is leftwardly inclined such that the smaller in height or volume per length, the farther away from the stream-splitting duct 26; and six upper nozzles 18 are provided on a bottom surface of the upper duct 28.
  • bottom surface of the lower duct 30 is rightwardly inclined such that the smaller in height or volume per length, the farther away from the stream-splitting duct 26; and six lower nozzles 20 are provided on a top surface of the lower duct 30.
  • a recovery duct 32 is provided on a left side surface of the heat-treatment chamber 12, on a side opposite to a side where the stream-splitting duct 26 is provided; and a filter 34 is provided at a lower portion of the recovery duct 32, below which filter is provided a heating section 36 comprised of burners.
  • a circulating duct 40 extends to a hot-air stream inlet of the blast fan 38 that is disposed underneath of the stream-splitting duct 26.
  • Hot-air stream produced by the blast fan 38 is divided vertically by the stream-splitting duct 26 to be flown into upper and lower ducts 28, 30. Hot air flowing through the upper duct 28 is blown out downwardly from the upper nozzles 18; and hot air flowing through the lower duct 30 is blown out upwardly from the lower nozzles 20.
  • Hot air having used for heat-treating the web W which runs between the upper and lower conveyer nets 22, 24, is recovered by the recovery duct 32 and then is sent, through the filter 34, to the heating section 36. Thus recovered air is again heated there, and returns to the blast fan 38 by flowing through the circulating duct 40.
  • the second block is constructed in the same manner as the first block is; and the web W passes through the first block and then through the second block.
  • the pair of upper and lower web-spreading nozzles 50, 52 for width-wisely spreading the web W are provided at rear of the second block.
  • a mechanism for supplying hot air to the pair of upper and lower web-spreading nozzles 50, 52 is same as above.
  • Fig. 3 is a perspective view showing how the lower nozzles 20 in the first block are arranged;
  • Fig. 4 being a plan view showing the first block, the second block, and the web-spreading nozzles 50, 52;
  • Fig. 8 being a vertical cross section view showing the upper nozzles 18 and the lower nozzles 20.
  • each of the upper nozzles 18 is comprised of; a base or main body 43 that is attached on a bottom surface of the upper duct 28 and is downwardly tapered at lower portion thereof; and a blow-off portion 45 that is downwardly extending from the tapered portion of the main body 43.
  • blow-off port 47 is provided in a form of a linear slit, while a pair of flanges 49 is formed along the blow-off port 47 so as to facilitate downward flowing of the hot air.
  • each of the lower nozzles 18 is comprised of; a base or main body 42 that is attached on a top surface of the lower duct 30 and is upwardly tapered at upper portion thereof; and a blow-off portion 45 that is downwardly extending from the tapered portion of the main body 42.
  • blow-off port 48 is provided in a form of a linear slit, while a pair of flanges 48 is formed along the blow-off port 46 so as to facilitate upward flowing of the hot air.
  • First characteristic feature of the embodiment resides in a manner of arranging the six upper nozzles 18 and the six lower nozzles 20 in each block; that is, the lower nozzles 20 and the upper nozzles 18 are disposed obliquely relative to the widthwise direction of the web W. This is contrary to the prior art where the upper and lower nozzles are arranged in parallel to the widthwise direction of the web W (Japanese Registered Patent No. 2764197).
  • the six lower blow-off ports 46 and six lower nozzles 20 are arranged in parallel to one another; and they are arranged at a slant angle ⁇ 1 (where 0° ⁇ 1 ⁇ 90°) relative to the widthwise direction of the web W.
  • the upper blow-off ports 47 and the upper nozzles 18 are arranged in parallel to one another; and they are arranged obliquely relative to the widthwise direction of the web W and relative to the lower nozzles 20.
  • the upper blow-off ports 47 and the upper nozzles 18 are arranged at a slant angle ⁇ 2 (where 0° ⁇ 2 ⁇ 90°) relative to the widthwise direction of the web W as shown in Fig. 4.
  • the upper duct 28 and the lower duct 30, which are in a same size, are disposed as shifted to each other in the web-conveying direction, by a dimension "A".
  • the upper nozzles 18 and the lower nozzles 20 in the second block are arranged in the same manner as those in the first block except that arranging directions of the upper nozzles 18 and the lower nozzles 20 are reversed, relative to the widthwise direction of the web W. More specifically, the lower nozzles 20 have an angle - ⁇ 1 relative to the widthwise direction of the web W and the upper nozzles 18 are arranged at an angle - ⁇ 2 relative to the widthwise direction of the web W.
  • Second characteristic feature of the embodiment resides in that the pair of upper and lower web-spreading nozzles 50, 52 for putting the web W in open width are provided at rearward of the second block.
  • the pair of upper and lower web-spreading nozzles 50, 52 are distinguished from the upper and lower nozzles 18,20 in configuration of blow-off ports 53 whereas other constructions are substantially in common.
  • the blow-off ports 53 has a wide-angle v-shaped configuration in a plan view in a manner that a straight line is bent as angled at a center line of the conveyance passage of the web W.
  • the blow-off ports 46 on the left side are constructed to blow hot blast leftward; and the blow-off ports 46 on the right side are constructed to blow hot blast rightward.
  • the web W is conveyed in an overfed or lengthwise loosened state as interposed between the upper conveyer net 22 and the lower conveyer net 24.
  • the web W In order to convey the web W in an overfed state, the web W must be fed faster than the running speed of the upper conveyer net 22 and the lower conveyer net 24 and must be conveyed without application of tension.
  • the upper nozzles 18 and the lower nozzles 20 blow hot blast against the web.
  • the upper nozzles 18 and the horizontally elongated lower nozzles 20 are disposed obliquely relative to the widthwise direction of the web W; accordingly, the hot blast strikes against the web at along lines oblique to the widthwise direction of the web W, from above and below; thereby achieving the rubbing effect on the web not only in the lengthwise direction of the web W but also in the widthwise direction of the web. Since the upper nozzles 18 and the lower nozzles 20 are disposed to intersect each other in a plan view, the rubbing effect can be given without having the web W meandering in one direction. As shown in Figs. 1 and 4, the rubbing effect is increased because the upper duct 28 and the lower duct 30, which are same in size, are disposed as shifted with each other by a dimension "A" in the web-conveying direction.
  • the web W having passed through the first block then passes through the second block.
  • the upper nozzles 18 and the lower nozzles 20 are arranged at different slanting directions from those in the first block, a different rubbing effect from that in the first block can be imparted to the web W.
  • the rubbing effect can be given in the widthwise direction of the web W as well as in the lengthwise direction of the web W, in a same manner as in the first block.
  • the web W having passed through the second block then passes between the upper and lower web-spreading nozzles 50, 52.
  • the hot blast is blown out rightward on the right side of the apparatus and leftward on the left side thereof, the web W is width-wisely spreaded and conveyed out from the exit 16 in such a width-wisely spreaded state.
  • the heat treatment apparatus 10 can impart the rubbing effect to the web W not only in the lengthwise direction of but also in the widthwise direction of the web W.
  • the web W may be conveyed out in a width-wisely spreaded state, by passing between the pair of the upper and lower web-spreading nozzles 50, 52.
  • FIG. 5 A second embodiment of the invention will be described with reference to Fig. 5, which differs from the first embodiment in configuration of blow-off ports 46, 47 on the upper nozzles 18 and the lower nozzles 20.
  • each of blow-off ports 46, 47 in this embodiment extends along a smooth curve (for example, an arc) whreas blow-off ports 46, 47 in the first embodiment extends along a straight line.
  • the curved blow-off ports 46, 47 are disposed as oblique to the widthwise direction of the web W; and the upper nozzles 18 and the lower nozzles 20 are arranged in a manner to intersect each other.
  • the rubbing effect can be imparted to the web W not only in the lengthwise direction of but also in the widthwise direction of the web W.
  • FIG. 5 illustrates the blow-off ports 46 of the lower nozzles 20 in solid lines, the blow-off ports 47 of the upper nozzles 18 in dotted lines, and the lower conveyer net 24 and the web W in two-dot chain lines.
  • Fig. 6 shows a third embodiment as well as Fig. 7 showing a fourth embodiment.
  • FIG. 6 differs from the first embodiment in planar configuration of blow-off ports 46, 47 of the upper nozzles 18 and the lower nozzles 20.
  • each of lower blow-off ports 46 on lower nozzles 20 has av-shaped orwide-angle v-shaped configuration which is left-to-right-wise symmetric about a widthwise-center line of the web W.
  • each of upper blow-off ports 47 on upper nozzles 18 has a v-shaped or wide-angle v-shaped configuration which is left-to-right-wise symmetric about a widthwise-center line of the web W, while the blow-off ports 47 intersect the blow-off ports 46 in the lower nozzles 20, in a plan view.
  • the rubbing effect can be imparted to the web W not only in the lengthwise direction of but also in the widthwise direction of the web W.
  • blow-off ports 46 in this embodiment is modified from that of the third embodiment having a v-shaped or wide-angle v-shaped configuration, in a way that a width-wise linear portion is interposed on a central portion of the wide-angle v-shaped configuration, as shown in Fig. 7.
  • the blow-off ports are disposed also as oblique to the widthwise direction of the web W, so that the rubbing effect can be given in the widthwise direction of the web W.
  • FIG. 9 an arrangement shown in which two slit-shaped blow-off ports 54 are disposed as in parallel to each other, on upper and lower nozzles 1.
  • an arrangement shown in Fig. 10 may be employed, in which a plurality of punched holes 56 are provided on the nozzles 18, 20.
  • the upper nozzles 18 and the lower nozzles 20 may be constructed such that; rotary dampers, which are provided at inside of nozzles, are rotated to permit hot blast to be intermittently blown out of the upper and lower nozzles 18, 20, in a manner as disclosed in Japanese Registered Patent No. 2860441; thus presenting a further rubbing effect.
  • the pair of upper and lower web-spreading nozzles 50, 52 for spreading the web W may be omitted if the web W is adequately put in open width; whereas such web-spreading nozzles 50, 52 are provided in foregoing embodiments.
  • a rubbing effect is imparted to a long or continuous web (W) not only in its lengthwise direction but also in its widthwise direction.
