The flown waste fibers generated by the relation of the warps 5 with the dropper 7 and the heddle 8 are individually sucked and caught by the flown waste fiber-sucking tubes and subsequently carried into a filter-having first fiber-collecting box 12 through the first fiber-collecting duct 11A and further into the second fiber-collecting box 15 of a central fiber-collecting device 21.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cotton wool collecting device for a loom, and more specifically, it individually sucks cotton wool generated by a loom by suction pipes arranged above and below a warp group. The present invention relates to a fly cotton collecting device configured to be pneumatically fed to a cotton collecting device after being collected.

[0002]

2. Description of the Related Art In a loom during weaving, the warp yarns sent from a yarn beam toward a dropper and a heddle are
Due to the vibration caused by the shedding motion and the engagement of the warp with the dropper and the heddle, a strong vertical impact load and tension act. As a result, a part of the monofilament constituting the warp is separated from the surface of the yarn and scattered as fly cotton. As such a cotton wool collecting means, a method of disposing a porous cotton wool suction pipe below the running area of the warp, or blowing away the cotton wool accumulated on the machine base or floor by compressed air The method is known.

[0003]

[Problems to be Solved by the Invention] Fly cotton is scattered in the air,
Alternatively, the environment of the weaving room is deteriorated by falling and depositing on the floor surface or the machine stand. Further, if weaving is continued with the cotton wool adhered to the surface of the warp, product defects such as warp breakage and weaving may occur. Then, the weaving efficiency is lowered by stopping the operation of the loom to repair the defective portion,
Omission of the woven process is also hindered. In particular, in high-speed looms such as air jet loom, the amount of fly waste increases in proportion to the improvement in productivity, and it is required to prevent product defects and deterioration of the weaving environment due to the large amount of fly waste. .. As a solution to this problem, as described in the preceding paragraph, a method of disposing a perforated pipe below the running area of the warp and sucking and collecting the cotton wool or a method of blowing the cotton wool with compressed air has been proposed. However, in either method, it is difficult to adjust the suction pressure and the blow-off pressure, and there are problems that the cotton collecting action is partial and that the blown cotton flies again when blown off. The effect of removing the cotton dust is not obtained.

[0004]

Means for Solving the Problems As a means for solving the above problems, according to the present invention, between the left and right side frames of a loom, at a place where a cotton wool is generated, substantially perpendicular to the running direction of the warp and above and below the warp group Wind fluff suction pipes with slits for suction are arranged over the entire width of the alignment, and one end of these dust fluff suction pipes is connected to a cotton collecting device via a cotton dust collecting duct. A cotton collection device is provided.

[0005]

[Function] The cotton wool generated from the warp during weaving is negatively sucked through the slits of the cotton wool suction tube disposed at the cotton wool generation point and above and below the warp group, and one end of the cotton wool suction tube is drawn. The air is sent to the cotton collecting device through a cotton collecting duct connected to and is collected in a cotton collecting box in the cotton collecting device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of a main part of a loom exemplifying a position of a cotton wool suction pipe, and FIG. 2 shows a connection state of a cotton wool suction pipe, an individual cotton collecting device and a central cotton collecting device. It is a perspective view.

As shown in FIG. 1, side frames (16A) and (16B) are erected so as to face each other on both left and right sides of the loom (19), and between the side frames (16A) and (16B). A yarn beam (4) wound with the warp (5) from the upstream side to the downstream side of the traveling path of the warp (5), a back roll (6), a dropper (7) for detecting cutting of the warp (5), A heddle (8) for transmitting the shedding motion to the warp (5), a cross roll (9), and a cross beam (1) for winding the woven cloth.
0) are sequentially arranged. And, in the place where the cotton wool is generated between the side frames (16A) and (16B), the warp (5)
Slits (1A) that are substantially orthogonal to the running direction (F) of the warp yarn, and are located above and below the warp group (5) over the entire alignment width.
Suction tubes (1), (2) and (3) of cotton wool (20) are arranged so as to open (2A) and (3A). In the illustrated example, most of the cotton wool (20) is engaged with the warp threads (5) and the dropper (7) as well as the warp threads (5).
Paying attention to the fact that occurs due to the engagement between the and heddle (8),
The first cotton wool suction tube (1) is arranged below the warp group (5) on the front side of the dropper (7), and at the place after passing the dropper (7), below the warp group (5). Two cotton wool suction tubes (2) are provided. Further, in order to suck the fly cotton (20) generated by the opening movement of the warp (5) given by the heddle (8), the third yarn is provided above the warp group (5) on the front side of the operation region of the heddle (8). The cotton wool suction tube (3) is provided. These cotton wool suction tubes (1), (2) and (3) have their longitudinal directions substantially orthogonal to the running direction of the warp threads (5) and extend over the entire area of the aligned width above and below the warp thread group (5). The relative mounting positions are adjusted so that the suction slits (1A) (2A) (3A) are opened.

As shown in FIG. 2, at one end of the fly cotton suction pipes (1), (2) and (3), a filter built-in type primary cotton collecting box (12) is provided via a primary cotton collecting duct (11A). ) And 1
An individual cotton collecting device (18) including a secondary suction fan (13) is connected. The individual cotton-collecting device (18) is provided for each unit of the loom (19), but each primary cotton-collecting box (12) of the individual cotton-collecting device (18) is as shown in FIG. Through the secondary cotton collecting duct (11B) and the automatic damper (14), the sequence control circuit (17), the secondary suction fan (not shown) and the secondary cotton collecting box (1)
5) is connected to a central cotton collecting device (21).

The operation sequence of the device of the present invention will be described below.
When the loom (19) is in operation, the warp (5) runs through the section from the yarn beam (4) to the dropper (7).
During the running of the yarn, the fly fluff (20) is generated due to the impact and the change of the tension due to the opening movement and the engagement of the dropper (7), the heddle (8) and the warp (5). This fly cotton (20) adheres to the warp (5) and moves, but the primary suction fan (1
By activating and placing 2) the suction slit (1) before the dropper (7) and the warp (5) are engaged.
It is continuously sucked into the first cotton wool suction tube (1) through A). The cotton wool (20) generated by the engagement between the dropper (7) and the warp (5) is separated from the warp (5) when the opening movement by the heddle (8) is transmitted to the warp (5),
Through the suction slits (2A) of the second cotton wool suction pipe (2) and the suction slits (3A) of the third cotton wool suction pipe (3), which are placed above and below the warp group (5), respectively. It is continuously sucked into the suction pipes (2) and (3). The fly cotton (20) sucked into the first to third suction pipes (1), (2) and (3) under negative pressure receives the negative pressure suction force generated from the primary suction fan (13) to be the primary Flow in the cotton collecting duct (11A),
Reach into the primary cotton collection box (12). Since a filter (not shown) is provided in the primary cotton-collecting box (12), the fly cotton (20) that has been fed into the primary cotton-collecting box (12) is separated from the sucked air flow. In this state, it is stored for a fixed time. Next, using the sequence control circuit (17) of the central cotton collecting device (21), the automatic damper (14)
Are closed in a predetermined operation sequence. By opening a plurality of automatic dampers (14) at predetermined time intervals for a certain period of time, a negative pressure suction force by the secondary suction fan is applied to the fly dust (20) accumulated in the primary cotton collection box (12). Works. As a result, the fly cotton (20) in the primary cotton collecting box (12) is pneumatically transported in the secondary cotton collecting duct (11B), and the secondary cotton collecting box (15) of the central cotton collecting device (21). Will be automatically collected within. On the other hand, the primary suction fan (13)
The air flow generated by the start-up is separated from the fly fluff (20) when passing through the filter of the primary cotton collection box (12), so that the primary suction fan (1
It flows out from 3). Since the exhaust air from the primary suction fan (13) does not substantially contain the fly fluff (20), it can be used for cleaning the loom (19) and the weaving room.

As can be understood from the above description, the fly dust (20) generated in the running region of the warp (5) is continuously sucked by the individual cotton collecting device (18) which is always in the operating state. And stored in the primary cotton collection box (12). Then, the fly wastes (20) accumulated in the respective primary cotton collection boxes (12) among the plurality of loom (19) are intermittently passed through the sequential switching of the automatic damper (14) by the sequence control device (17). The air feeding order is adjusted, and the air is collected in the secondary cotton collecting box (15) of the central cotton collecting device (21). When the operation of the loom (19) is completed, the central cotton collecting device (21) and the individual cotton collecting device (18) are stopped, and the cotton wool (20) collected in the secondary cotton collecting box (15) is taken out.

[0011]

According to the present invention, the fly is removed by forcibly sucking a negative pressure at the source, so that the dropper may not operate properly due to the attachment of the fly, warp breakage, or weaving. Problems are prevented. Further, since the fly dust suction tube arranged between the side frames of the loom has no movable portion, a fly dust collecting device having a simple structure and easy maintenance is provided.
As a result, the quality of the woven fabric is improved and labor is saved, which is far superior to that of the conventional device.
