Description

[Detailed description of the invention] The present invention relates to a fabric drying device.

As a fabric drying device, net conveyors are arranged in multiple stages, upper and lower, and the rotation direction is opposite for each stage, and the fabric is sandwiched between the upper and lower adjacent net conveyors, and the upper and lower net conveyors are There are known devices that blow hot air from the air. An example of such a fabric drying apparatus will be briefly explained with reference to FIG. 1. 1 is a drying chamber, 2a, 2
b is a pair of cloth supply rollers; 3, 4, 5, and 6 are endless net conveyors each made of composite fiber yarn or metal wire; 7 is a roller for moving each net conveyor;
The above net conveyor 3.4.5.6 is rotated in the opposite direction for each stage, and the net conveyor 4 of the second stage from above
It is placed in a relaxed state on top and transferred to the rear (to the right in Figure 1) between it and the bottom surface of the first stage nonet conveyor 3.
Next, the fabric Ak is transferred onto the third-stage net conveyor 5, sandwiched between it and the bottom surface of the second-stage net conveyor 4]]]11, and then transferred to the fourth-stage net conveyor 6.
Upper E transfer L is sandwiched between the lower surface of the third stage net conveyor 5 and transferred to the rear, and during this transfer, the above fabric L
The fabric is dried by blowing hot air from the nozzles JV8a and 8a arranged in a staggered manner in the upper and lower hot air ducts 1-8.8 to bend the fabric in a wavy manner and float it. It is designed to be sent from there onto the scraper 9. Note that the hot air blown from the nozzle 1vBa is heated by a heater (not shown) in the drying chamber, and is heated by a fan (not shown).
(not shown), a part of which is exhausted by an exhaust duct (10).

However, in the conventional fabric drying apparatus described above, the net conveyors 3 to 6 are simply wound around the respective driving rollers 7, so the net conveyors 3 to 6 tend to meander, which is troublesome to correct. Ta. -1, In order to facilitate the above correction, all the driving rollers 7 were arranged outside the drying chamber 1 as shown in the figure, so the net conveyors 3 to 6 were installed in the drying chamber 1. It is necessary to provide an inlet and an outlet, and the disadvantage is that the loss of thermal energy is large. In addition, when the net conveyors 3 to 6 are made of metal, the wear due to contact with the driving roller 7 is large, and the metal wires of the net conveyors 3 to 6 are repeatedly bent and damaged. .

This invention provides a drying device for fabrics in which the perforated conveyor made of a net or perforated plate does not meander at all, so its driving roller can be placed inside the drying chamber, and the net or perforated plate is not bent. All that is offered.

In other words, this invention provides a method in which perforated conveyors made of nets or perforated plates are arranged in multiple stages, one above the other, with the direction of rotation opposite to each other in each stage, and the fabric is sandwiched between the vertically adjacent perforated conveyors and transferred. Meanwhile, in a fabric drying device that blows hot air onto the fabric from above and below,
The fabric drying apparatus is characterized in that the above-mentioned porous conveyor is formed by connecting a large number of porous plate-shaped bodies elongated in the width direction with a pair of left and right endless chains.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.

In Fig. 2, 11, 12, 13, and 14 are multi-hole conveyors, and as shown in Figs. 3 and 4,
Both ends of a large number of rectangular porous plates 5 which are short in the length direction and long in the width direction are connected by end chain 16 at short and equal pitches.

That is, a rectangular frame 17 is formed using angle materials, a net 18 made of synthetic fiber yarn or metal wire is stretched over this frame 17, and both left and right ends of the frame 7 are connected to connecting fittings 1.
9 to the inner pin link plate 1, 16a of the end chain 16. In this case, the frame 17 is set so that its length (the dimension in the longitudinal direction of the endless chain 16) is slightly smaller than twice the pitch of the endless chain 16, and is attached to each inner pin link plate 16a. is preferred.

The above-mentioned multi-hole conveyor 11, 12, 13, 14 has chain sprockets at both front and rear ends, as shown in Figure 2.
・It is wrapped around 20 and rotated. In this case, the second stage from the top of the multi-hole conveyor 12, the one (supply side) chain sprocket) 20, and the fourth stage of the multi-hole conveyor 1 from the top.
The chain sprocket 20 at the rear (feeding side) of No. 4 is provided outside the drying chamber 1, and the remaining chain sprocket 2o
are all provided within the drying chamber 1. Note that the straight portion of the endless chain j6 is supported from below by a guide rail (L/-1, not shown).

In the above structure, the fabric A is supplied onto the second-stage perforated conveyor 12 as in the past, is sandwiched between the bottom surface of the first-stage (D) perforated conveyor 11, and sent to the rear. It is placed on the third-stage perforated conveyor 13, sent forward with a 1/ic gap between it and the bottom surface of the second-stage perforated conveyor 12, and then placed on the fourth-stage perforated conveyor 14. ,3
It is sandwiched between the lower surface of the multi-hole conveyor 13 of the tier and sent to the rear, where it is dried. Therefore, the above-mentioned porous conveyors 11 to 14 are connected to the end chain 1f3 located at both ends in the width direction. Since it is driven by the chain sprocket 20 through the r, there is no meandering like in conventional net conveyors. Therefore, Figure 2! As shown, except for the supply end of the second-stage multi-hole conveyor 12 and the delivery end of the fourth-stage multi-hole conveyor 14, the rest can be placed inside the drying chamber l, so that the drying chamber By reducing the number of openings in 1, the loss of thermal energy can be significantly reduced. In addition, the porous conveyors 11 to 14
When changing direction at both front and rear ends, use the end chain 16
Since the porous plate-like body 15 itself is kept flat without being curved, the porous plate-like body 15 is often damaged by bending or abrasion.
1'', if the pot becomes dirty, only the porous plate-like body 15 can be removed and replaced, or it can be washed.

In the embodiments described above, the number of stages of the multi-hole conveyors 1 to 14 can be increased or decreased as appropriate. 1f.degree. C. Instead of the net 18, a perforated plate made of synthetic resin or metal may be completely fixed, and in this case, installation and cleaning are easier than with a net. In addition, in the case of a metal perforated plate, it is possible to form it into a box shape and fix it directly to the link plays 1 and 15a of the endless chain 16 without using the frame 17 made of angle material. can. Of course, the length and pitch of the porous plate-like body 5 can be changed.

As explained above, in this invention, a multi-porous conveyor is formed by connecting a large number of porous plate-like bodies with an end chain, so that there is no meandering of the perforated conveyor, and the supply side end and By locating all but the delivery end in a drying chamber, the loss of thermal energy can be significantly reduced, and the multi-hole conveyor is easier to maintain and has a longer service life.
