Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for transporting a rope-shaped textile product using a fluid.

[Conventional technology]

Textile products such as fabrics can be processed by tying them into an endless rope and circulating them through the processing tank.
When transporting textile products from one process to the next, it is common practice to inject fluid into a transport path for the textile products, and to transport the textile products by the flow of this fluid.

An example of a device for transporting textiles using a fluid is a liquid flow treatment device as shown in FIG. 5. This device includes a retention section 1 for temporarily retaining the processing fluid and textiles, a transfer path 2 through which the processing fluid and textiles travel, and an injection section 3 for injecting the processing fluid into the transfer path. . Reference numerals 4, 5, and 6 are processing fluid suction ports provided in the retention section 3, and the processing fluid is collected into a processing fluid recovery path 9 equipped with a pump 7 and a heat exchanger 8, and is then sent from the processing fluid supply port 10. It is designed to be circulated and supplied to the injection section 3.

In such a device, it is an important issue that the textile product moves smoothly within the transfer path 2. Therefore,
In order to set the feeding of textiles in a favorable state, conventionally, in such devices, the gap between the injection ports in the injection section 3 can be adjusted to change the injection pressure of the fluid.

Such a fluid injection unit 3 with an adjustment function
For example, as shown in FIG. 6, an inner cylinder 11 whose outer periphery is formed with a tapered surface 11a and an outer cylinder 12 whose inner periphery is formed with a tapered surface 12a along this tapered surface 11a are combined. One example is one in which fluid is injected from the gap between the inner cylinder 11 and the outer cylinder 12 (Japanese Utility Model Publication No. 180297/1983). In this device, the root part of the inner cylinder 11 is formed into a male thread and is screwed into the female thread part 13 fixed in the outer pipe 14 of the injection part 3, so that the inner cylinder 11 can be rotated in the direction of arrow A. When this happens, the inner cylinder 11 itself moves back and forth as shown by arrow B. Therefore, by moving the inner cylinder 11 itself, the gap between the tapered surface 11a and the tapered surface 12a becomes wider or narrower, and the treatment liquid injection pressure can be changed. However, in this device, in order to rotate the inner cylinder 11, the operator has to put his/her hand into the injection part 3 and turn the end of the inner cylinder 11 by hand, making the adjustment work very difficult. It was both troublesome and dangerous. Furthermore, under high temperature and pressurized conditions after the start of operation, even if the initial gap setting was inappropriate and trouble occurred in transporting textiles, it was impossible to correct it at that stage.

On the other hand, even if you do not put your hand inside the injection part 3,
An example of a device that can adjust the treatment liquid injection pressure from outside the transfer path 2 is the device disclosed in Japanese Patent Application Laid-Open No. 49-94979. As shown in FIG. 7, this device uses a so-called "bench ridge" as the fluid injection section 3, and has a constriction section 15a on the liquid discharge side of the outer tube 15 of the injection section 3. ,
The outer cylinder 17 is loosely fitted on the downstream side of the inner cylinder 16, and the outer cylinder 1
The processing liquid is ejected from the gap formed between the downstream end of the tube 7 and the inner peripheral surface of the outer tube 15 (the flow of the processing liquid is shown by arrows).

A pin 18 protrudes from the outer peripheral surface of the outer cylinder 17 and engages with an elongated hole 20 formed at one end of the connecting lever 19. A support shaft 21 that penetrates the outer tube 15 and projects to the outside is integrally attached to the other end of the connecting lever 19, and a lever 22 is further attached to the outer protrusion of the support shaft 21. It is being Therefore, when this lever 22 is moved in the direction of arrow C, the outer tube 17 is moved from side to side between the inner tube 16 and the outer tube 15. Note that 23 is a fan-shaped guide that is integrally attached to the outer peripheral surface of the outer tube 15, and a tightening screw 24 on the lever 22 side is inserted into an arc-shaped long hole 23a formed in this guide 23. , by screwing in this tightening screw 24, the lever 2
2 position (and therefore the left-right position of the outer cylinder 17)
can be fixed. According to this device, by rotating the lever 22 that protrudes outward by a predetermined angle, the outer cylinder 17 moves to an appropriate position, making it possible to adjust the injection pressure to a favorable level.

[The problem that the idea aims to solve]

However, in the above device, the movement of the outer cylinder 17 is made to follow the rotation of the lever 22 and the connecting lever 19 about the support shaft 21, and the pin 18 is inserted into the elongated hole.
0 and has some looseness so that it can move smoothly, so the accuracy of gap adjustment is poor. In addition, since the fitting tolerance between the outer cylinder 17 and the inner cylinder 16 is made loose, the outer cylinder 17 and the constricted part 15a
If the gap between the If the fluid becomes unbalanced, troubles such as twisting and entanglement of the textiles transferred in the transfer path 1 occur, which is undesirable. That is, the twisting of the textile product impedes uniform processing, and there is a problem that it is difficult to take out the product from the apparatus after the processing is completed. Furthermore, in the above device, the pin 18 is integrally attached to the outer cylinder 17,
Since the support shaft 21 is integrally attached to the outer tube 15, these cannot be removed. Therefore, even if it is necessary to replace the inner tube 16 and the outer tube 17 with ones of different diameters due to a change in conditions such as a change in the fabric weight of the textile product, the outer tube 17 cannot be replaced. It cannot be exchanged for one with a different diameter.

This idea was devised in view of these circumstances, and is an excellent textile transfer device that allows the fluid injection pressure to be easily changed by operating from outside the transfer path, and that does not cause uneven flow. Its purpose is to provide.

[Means to solve the problem]

In order to achieve the above object, the device for transferring textile products using a fluid of this invention is an apparatus for transferring textile products using a fluid, in which a fluid is fixed in a transfer path of the textile product, a guide cylinder, and the guide tube. The liquid is injected into the transfer path through a gap between the cylinder and a sliding cylinder arranged concentrically on the outside of the cylinder. a tapered surface formed on the inner periphery of the tip and facing the tapered surface of the guide tube; a first threaded portion formed on the outer periphery of the sliding tube; a worm gear that meshes with the first threaded portion of the sliding tube in a perpendicular direction; a rotation drive means that rotates the worm gear from outside the transfer path; a threaded portion that is threadedly engaged with the second threaded portion of the cylinder;
By rotating the worm gear, the sliding tube is rotated and at the same time moved forward and backward in the axial direction, thereby adjusting the gap between the guide tube and the sliding tube.

[Effect]

That is, in the fluid-based textile transfer device of this invention, fluid is injected into the transfer path from a gap between a predetermined guide tube and a sliding tube, and the sliding tube is pivoted relative to the guide tube. The injection pressure of the fluid can be adjusted by moving it forward and backward in the direction. Since the sliding tube is moved forward and backward by rotating a worm gear from outside the transfer path that engages with a threaded portion formed on the outer circumferential surface of the sliding tube, the sliding tube does not wobble. There is no movement, and it can be advanced and retreated with precision. In addition, if the sliding tube is configured with a tapered tube having a tapered surface and a holding tube that holds this inside in a detachable manner, when the basis weight of the textile item changes, the guide tube and taper tube The tube can be easily exchanged for one with a different diameter, allowing for a wide range of applications.

Next, this invention will be explained in detail based on examples.

〔Example〕

FIG. 1 is a partial cross-sectional view showing the structure of the fluid ejecting section 3 of the textile transfer device of this invention. Other parts are the same as those in FIG. 4 and are omitted. However, a rope-shaped textile product is introduced into the injection section 3 as shown by arrow P.

In the figure, 30 is an outer tube of the injection part 3, which is provided in the middle of the textile article transfer path. Reference numeral 31 denotes a guide tube that is detachably attached to the textile article entrance side of the injection section 3 via a screw 41, and the entrance side is open in a flap shape so that the textile article can easily enter. A tapered surface 31a is formed on the outer circumferential surface of the guide tube 31 on the textile product outlet side.
On the other hand, 32 is a tapered cylinder held inside the holding cylinder 33, and the edge 32 on one end side is folded back to the outside. It is attached removably. The tapered surface 31 of the guide tube 31 is provided on the inner circumferential surface of the tapered tube 32 on the textile product outlet side.
A tapered surface 32a parallel to a is formed, and the processing fluid is ejected from the gap between this tapered surface 32a and the tapered surface 31a of the guide cylinder 31 as shown by the arrow. Note that 10 is a processing fluid supply port (see FIG. 5).

A worm wheel 36 is fitted onto one end of the holding cylinder 33 that holds the tapered cylinder 32 via a sliding key 35, and rotates integrally with the holding cylinder 33. Further, the outer circumferential surface of the central portion of the holding cylinder 33 is thickly raised, and a male thread is carved on the outer circumference. And this male thread part 3
3a is a guide 38 extending from the inner wall side of the outer tube 30;
It engages with a female thread carved into the tip of the.

The worm wheel 36 meshes with a worm gear 37 disposed perpendicularly to its rotation axis, and rotation is applied in the circumferential direction by the rotational action of the worm gear 37, so that the holding cylinder 33 and the tapered cylinder 3 are rotated.
Rotates integrally with 2. Accordingly, with this rotation, the holding cylinder 33 is screwed in via the threaded portion with the guide 38, or is screwed back in the opposite direction, so that the tapered cylinder 32 is moved in the left-right direction (axial direction). Begins to move. When the tapered tube 32 moves to the left in the drawing, the gap with the guide tube 31 narrows and the processing fluid injection pressure increases, and when the tapered tube 32 moves to the right in the drawing, the gap with the guide tube 31 widens. As a result, the processing fluid injection pressure becomes lower.

The rotation of the worm gear 37 is achieved by applying rotation to a rotating shaft 39 that passes through the injection section 3 laterally, as shown in FIG. 2, which is a sectional view taken along line A-A' in FIG. It will be done. The rotating shaft 39
is adapted to rotate integrally with the worm gear 37 by a sliding key (not shown), and can be rotated by turning a handle 40 attached to one end. Note that a watertight bearing mechanism is provided at a portion of the rotating shaft 39 that projects outward from the injection section 3, and holds the rotating shaft 39 rotatably from the left and right sides.

Note that 42 is a guide ring that guides the holding cylinder 33 that moves in the axial direction from the outside, and a connecting cylinder that extends laterally from the guide 39 by a plurality of rib plates 42a provided at predetermined intervals in the circumferential direction. It is integrally fixed to 44. Reference numeral 45 denotes a guide ring that guides the tapered cylinder 32 moving in the axial direction from the inside, and is integrally attached to the outer peripheral surface of the guide cylinder 31 by a plurality of rib plates 45a provided at predetermined intervals in the circumferential direction. is attached to.

With the above configuration, this textile transfer device has the following features:
By simply turning the handle 40 protruding to the outside of the injection section 3, the tapered cylinder 32 inside the injection section 3 can be easily moved in the axial direction, making it possible to finely adjust the processing fluid injection pressure. Moreover, due to this adjustment, the axial center of the moving tapered cylinder 32 does not shift, and the jet nozzle always has a uniform gap in the circumferential direction, so that the jet flow does not become unbalanced.

Further, the tapered cylinder 32 is simply screwed to the holding cylinder 33 and can be easily removed. Therefore, if the weight of the processed material is different, etc.
If you want to significantly change the processing fluid injection pressure, simply remove the screws 41 that fix the guide tube 31 and the screws 34 that fix the tapered tube 32, and replace them with guide tubes and sliding tubes of different diameters. The processing fluid injection pressure can be changed significantly.

In the above embodiment, the worm wheel 36 is externally fitted onto the holding tube 33 via the sliding key 35, but the worm wheel may be formed by forming gear teeth on the outer periphery of the holding tube 33 itself.

Furthermore, in the above embodiment, the part that slides due to the rotation of the worm gear 37 is constructed by combining two parts, the tapered cylinder 32 and the holding cylinder 33, but this part is as shown in FIG. Alternatively, the cylinder 50 may have a tapered surface 32a on its inner circumference and a threaded portion 33a on its outer circumference.
However, as shown in the above embodiment, it is preferable to separate the tapered tube 32 into two parts and detachably attach it, since it is sufficient to replace only the tapered tube 32 when replacing parts with different diameters. .

Further, in the embodiment described above, a handle 40 protruding outside the injection section 3 is provided as a means for rotating the worm gear 37, but an electric motor may be connected instead. When an electric motor is used, gap adjustment can be electrically controlled, resulting in labor savings.

Note that the textile product transfer device of this invention is not limited to the one in which the textile product transfer path 2 is attached to the lower side of the retention section 1, as shown in FIG. , any type may be used as long as the injection mechanism having the above configuration is applied. For example, as shown in FIG. 4, even if the textile article transfer path 2 is formed above the retention section 1, the textile article is continuously conveyed through the spiral tube using fluid. or transport path 2
Alternatively, the textile articles may be configured to travel in the retention section 1 alternately in forward and reverse directions.

[Effect of idea]

As described above, according to the textile product transfer device of this invention, in the fluid injection part, a guide tube and a sliding tube having mutually parallel tapered surfaces are combined,
Since the sliding tube is moved forward and backward in the axial direction with respect to the guide tube by a worm gear that can be rotated from outside the transfer path, the gap between the guide tube and the sliding tube can be adjusted from the outside of the transfer path. It can be easily and accurately adjusted. Since this forward and backward movement is always performed straight in the axial direction without rattling, drifting does not occur due to this operation. In addition, if the sliding tube is made up of a tapered tube and a holding tube that holds it detachably, the guide tube and the tapered tube can be used to adjust the diameter of the guide tube and the tapered tube when the fabric weight of the textile item changes. It can be easily replaced with a different one, and has the effect of widening the range of application.
