Description

[Detailed Description of the Invention] The present invention relates to a rope dewatering device that dewaters water impregnated in a fabric such as a knitted fabric, particularly a knit product, by converting it into a rope shape.

As is well known, this type of fabric cannot be dehydrated under high pressure when it is dehydrated with pressure rolls in a spread state because edge marks are generated in the folds of the fabric, and the dehydration rate is reduced.

For this reason, so-called rope dehydration, in which the fabric is dehydrated in the form of a rope, is said to be suitable for this type of fabric.

By the way, in this rope dewatering, if the rope-like fabric is simply passed between rolls, a gap is created between the rope-like fabric and the rolls, and sufficient dewatering cannot be achieved, so the rope must be passed around between the rolls many times.

This has the disadvantage that the number of rolls increases, making the device very complex and large.

Recently, rope dewatering devices that utilize suction force to rotate rope-like fabrics between rolls have been developed.
No. 7-5535 has been proposed, but with this device, the rotational transfer of rope-like fabrics is not necessarily smooth, and there is a risk that adjacent rope-like fabrics may overlap on the roll or conversely be too far apart. There was a drawback that sufficient dehydration was not avoided.

For this reason, the present invention utilizes the appropriate water absorption and anti-slip properties of the nonwoven fabric roll, and also allows the rope-like fabric to hang freely downward for a long time, thereby connecting the nonwoven fabric roll and the sag tolerance area in a spiral manner. An object of the present invention is to provide a rope dewatering device for a fabric that is wrapped and transferred in a shape.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

Reference numeral 1 denotes a frame of a dehydrator, and a pair of nonwoven fabric rolls 2 and 2' having the following structure are supported on this frame 1.

The nonwoven fabric rolls 2, 2' have hollow parts 3, 3' in the axial direction, and a shaft main body 5, which has a large number of through holes 4, 4' in its circumferential surface that communicate with the hollow parts 3, 3'. 5' side plates 6, 7.
6',? ', and this side plate 6, 7 or 6',? '
It is constructed by stacking a large number of nonwoven fabrics 8, 8' in a compressed manner between them.

The upper nonwoven fabric roll 2' is provided as a pressurizing means of a cylinder 9 so as to be vertically movable.

A motor 10 transmits its rotation to the nonwoven fabric rolls 2, 2' via gears, chains, etc.

Reference numeral 11 denotes a comb-like separator which is inserted between the nonwoven fabric rolls 2 and 2' and distributes the rope-like fabric A that is spirally wound around the lower nonwoven fabric roll 2. ) inward.

Reference numeral 12 denotes a detector such as a photosensor for detecting a position within the permissible range above the sagging length of the rope-like fabric A, and 13 represents a detector detecting a position within the permissible range below the sagging length.

A controller 14 controls the motor 10 based on the detection by the detectors 12 and 13.

15.15' is a hose connected to the nonwoven fabric rolls 2, 2', and this hose 15.15' is connected to a suction means (such as a pump).
(not shown).

As schematically shown in FIG. 3, a configuration in which a guide roll 16 pivotally supported by the frame 1 is provided approximately in the middle of both the detectors 12, 13, and the detectors 12, 13 are not mounted is also possible. In this example, the rope-like fabric A is wound and transferred between the nonwoven fabric rolls 2, 2' and the guide roll 16 in a spiral manner.

Next, to explain the operating state of the present invention, the rope-like fabric A fed to one end side between the nonwoven fabric rolls 2 and 2' is sequentially transferred by the rotation of the nonwoven fabric rolls 2 and 2', and hangs down to a predetermined position. After reaching the setting tolerance range, the nonwoven fabric rolls reach between the nonwoven fabric rolls 2 and 2' again, but in the process of being pulled up (in the state of being pulled up above the hanging position), it passes between the separators 11 and moves in the predetermined displacement direction. As described above, it reaches between the nonwoven fabric rolls 2 and 2', and is further wound around the nonwoven fabric rolls 2 and 2'.

In this case, due to the separator 11, the positional relationship between the rope-like fabric A and the previous winding position is shifted, so that they do not overlap.

Through this process, the rope-like fabric A is made into a nonwoven fabric roll 2.
．． 2' and the sagging permissible range area B in a spiral manner, and then pulled out from between the nonwoven fabric rolls 2 and 2'.

In this way, in the process of spirally winding and transferring the rope-like fabric A to the nonwoven fabric rolls 2 and 2', the nonwoven fabric rolls 2 and 2'
Due to the suction force acting on 2' and the appropriate water absorbency of the nonwoven fabric, the water impregnated into the rope-like fabric A is suctioned and dehydrated, thereby improving the water removal rate.

Further, when the free hanging length of the rope-like fabric A leaves the above-mentioned allowable range area B, for example, when it reaches a position above the allowable range area B, the detector 12 detects this, and the motor 10 , the rotation of the nonwoven fabric roll 2.2' is stopped and the sag length is corrected to the normal value.

As described in detail above, the present invention wraps a rope-like fabric around a non-woven fabric roll in a dangling manner, and transports the rope-like fabric in a spiral manner between the non-woven fabric roll and a sag-permissible range area. At the same time, the rope-like fabric is sorted by a separator, and the rope-like fabric is configured to hang freely, so the non-woven fabric roll's anti-slip and water-absorbing properties allow the rope-like fabric to spiral without slipping. It is possible to wrap and transfer the material in an orderly manner, and also to perform sufficient dehydration.

In particular, since it is lightly nipped with a nonwoven fabric roll and suction is performed using suction force, effective dehydration can be expected.

Also, since the droop is in a free state, it is effective as a dewatering device for fabrics that stretch easily, such as knit products, and since this free state is controlled through a detection means, no excessive pressure is applied to the fabric. It is.
