Description

[Detailed description of the invention] The present invention is a device that sends textile products between two net conveyors that are spaced apart from each other, and performs drying, heating, liquid treatment, etc. on the textile products without tension. The present invention relates to a conveyor and nozzle interval adjustment device that can adjust the gap formed by a net conveyor and the nozzle gap for injecting a processing medium such as air, steam, or liquid.

This device is used to pass fabric vertically or horizontally as a device that continuously and effectively performs liquid processing such as washing and dyeing, thermal processing such as scouring, bleaching, weight loss, or air processing such as drying under a tension-free meandering pattern. A pair of liquid-permeable, breathable conveyors are spaced apart with a gap between them, and the conveyors are arranged in a staggered pattern along the direction of movement of the conveyors, and a pressurized fluid such as liquid or gas is injected into the gap. The present inventor has proposed a continuous processing apparatus for fabrics, which is equipped with a group of fluid jet nozzles.

However, as various kinds of fabrics of different types are coming around, the width of the gap for fabric insertion formed by the upper and lower conveyors, or the direction of the fluid into the gap, must be adjusted according to the various types of fabrics to be treated. It is necessary to adjust the nozzle gap for spraying.

That is, when a fabric is made to meander without tension between two conveyors that are spaced apart, the meandering state (snake-like) formed between both conveyors is different depending on whether the fabric is thin or thick. In the case of fabrics with weak elasticity, the meandering width can be increased, so it is desirable to set the distance between both net conveyors to the maximum possible value, and in the case of thick fabrics or fabrics with strong elasticity, it is difficult to form a meandering pattern. It is necessary to narrow the gap between both conveyors and the spacing between the upper and lower nozzles to apply strong fluid jet pressure to the fabric.

In such cases, it has been impossible to perform appropriate processing depending on the thickness of the fabric using an apparatus in which the distance between the two net conveyors and the nozzle spacing are constant.

The present invention has been developed in view of the above, and it is possible to adjust the gap between both net conveyors according to the thickness of the fabric to be processed, and also to adjust the nozzle gap in accordance with the gap adjustment. The present invention provides a device that allows communication adjustment.

The present invention will be explained in detail below based on embodiments shown in the drawings.

1 is an endlessly formed upper net conveyor, 2 is a similarly formed lower net conveyor,
The upper net conveyor 1 is rotatably supported by a pair of guide rolls 3□, 3□ arranged laterally, and the lower net conveyor 2 is similarly arranged laterally. It is rotatably supported by a pair of guide rolls 4□, 4□, and a fabric transfer path 5 is formed between the upper net conveyor 1 and the lower net conveyor by a gap a.
is formed.

Guide roll 30.3 supporting the upper net conveyor 1
Channel-shaped support plates 6t, 62 are positioned at both ends of □, and channel-shaped support plates 7□, 62 are positioned at both ends of the guide roll 4□4□ that supports the lower net conveyor 2.
7□ is positioned, the support shaft 3'2 of the guide roll 3□ is directly supported by the support plates 6□ and 6□, and the support shaft 4'2 of the guide roll 4□ is directly supported by the support plates 7□ and 7□. It is supported.

The support shaft 3'1 of the guide roll 3□ is a horizontal slide body 8.
The support shaft 4'1 of the guide roll 4□ is supported by the support plates 7□, 72 via a horizontal slide body 9. The slide body 8 is held slidably in the lateral direction C by rails 10 formed on the support plates 6□, 62, and the position of the slide body 8 can be adjusted by operating the bundle 11. There is.

Similarly, the slide body 9 is held by rails 12 formed on the support plates 7□, 7□ so as to be slidable in the lateral direction.
The position of the slide body 8 can be adjusted by operating the bundle 13.

The support plates 70.7□ are fixed to a fixed frame (not shown), etc., and both ends of the upper support plates 6□, 6□ are A,
It is supported by respective shafts 14 for adjusting the B direction, that is, vertical movement.

That is, the shaft 14 is rotatably supported by a bearing 15, and a screw 16 is cut into the shaft 14. By rotating the support plate 14 with the bundle 17, the height of the support plate 6□, 6° can be adjusted.

18 is a drive chain for rotating the guide rolls 32, 4□ at a constant speed, and 19 is a tension adjustment roll thereof.

Reference numeral 20 denotes a nozzle arranged along the transfer direction of the net conveyors 1 and 2, and for injecting pressurized air or pressure liquid toward the fabric transfer path 5, and each nozzle 20 is arranged oppositely. The nozzles 20 are installed and supported between the support plates 6 and 62 and between the support plates 7□ and 7□, and each nozzle 20 is connected to a main pipe 21 for fluid supply by a flexible pipe 22.
are connected via.

The structure of this embodiment has been described above. Next, to describe its function, the guide rolls 3 and 3□ that support the endless net conveyor 1 are attached to support plates 6□ and 62 that move up and down by the operation of the bundle 17. Since the bundle 17 is supported, the gap a in the fabric transfer path 5 can be adjusted to a gap suitable for the type of fabric to be processed through the fabric transfer path by operating the bundle 17.

Furthermore, since each nozzle 20 that injects fluid toward the gap a is also supported by the support plates 6□, 62, the gap between the upper and lower nozzles is also adjusted according to the adjustment of the gap a, and therefore the gap There is an effect that the fluid pressure acting on the fabric is adjusted in conjunction with the magnitude of a.

In addition, since the shaft 14 that moves the guide roll 3□ up and down and the shaft 14 that moves the guide roll 3□ up and down have different structures, the width of the gap a may be made relatively wide near the fabric introduction port of the gap, for example. Further, the gap can be adjusted to be narrow near the fabric exit, and can be adjusted to a gap suitable for processing the fabric.

Furthermore, according to the present invention, the guide rolls 3 and 4□ can be moved in the C direction by operating the bundles 11 and 13, so the tension of the net conveyors 1 and 2 can also be adjusted as appropriate.

Furthermore, in this invention, both the upper and lower net conveyors 1 and 2 are
Since it is driven by a single shared motor via a condoless drive chain, both the upper and lower net conveyors 1
The rotations of the guide rolls 3 and 2 can be synchronized, and since the tension adjustment roll is in contact with the drive chain, a constant rotation is always transmitted without interfering with the movement of the negative guide roll 3□. It has the effect of being
