Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a water jet loom.

[Prior art]

The water jet loom sprays water in a straight line between the warp openings from a nozzle installed on one side of the machine, and inserts the weft using the water.The sprayed water spreads further away from the nozzle. As a result, the reed and warp threads become wet from both the nozzle side and the opposite side.Such water jet looms are especially suitable for weaving filament fabrics, and recently, the warp It has become common to use non-sizing and non-twisted yarns.The non-sizing and non-twisting warp yarns are coated with oil suitable for the purpose in order to improve filament cohesiveness and abrasion resistance. This applied oil is generally easy to fall off when the warp threads get wet with water, and if the oil that falls off adheres to a thread or heddle that has not been used in comparison, it becomes sludge or gum-like with a high viscosity. This may cause the warp threads in the threads to become uneven, or may become stuck between the heddles (
This causes a phenomenon called heald blocking. In this way, if the warp threads in the fabric are uneven or the healds are blocked, warps and meridional lines will appear in the fabric, and warp thread breakage and warp fuzz will also occur.

Therefore, in order to prevent this problem from occurring, VCl has so far installed a partition wall above the warp between the reed and heddle to shield the splashed water, thereby preventing the warp on the heald side from getting wet as much as possible. Measures have been taken to prevent oil from falling off the warp yarns, and to clean the oil and healds at intervals of several days to several weeks. but,
These countermeasures did not sufficiently solve the problem, and the cost of cleaning the liquid and healds was prohibitive.

[Purpose of the invention]

This development 8A was developed to solve the above-mentioned problems in weaving in a water jet loom, and even when using warp threads coated with oil without sizing or twisting, sludge or sludge may appear in the liquid state or heddles. To provide a water jet room in which oil does not adhere in the form of gum.

[Structure of the invention]

The present invention provides a partition wall for shielding water splashed above the warp between the reed and the heald, and a gutter for receiving the water falling down the partition wall member and allowing more water to fall onto the warp as the side approaches the nozzle. The water jet room is characterized by being provided with a member.

The present invention is characterized by the fact that in weaving using a conventional water jet loom, 1. High viscosity oil tends to adhere to the nozzle side, which is less likely to get wet, such as warps and warp threads, causing problems such as warp threads and warp knitting. This was done as a result of paying attention to the fact that there is a high occurrence of It is located in a water jet room that prevents highly viscous oil from adhering to the entire width of the liquid and healds.

〔Example〕

Hereinafter, the present invention will be explained based on illustrated examples.

FIG. 1 is a side view of a main part of a water jet room of the present invention provided with a shielding member that is integrally constructed of a partition wall member and a gutter member, and FIGS. 2 and 3 are partial perspective views showing examples of the shielding member, respectively. Figure, @41'21 f'i Fig. 5 is a graph of the distribution of scattered water captured by the partition wall in the width direction of the machine.

In Figures 1 to 3N, 1 is a reed, 2 is a heddle, 3 is a warp, 4 is a cross rail, 5 is a cross guide, a group of 6 cloth take-up rollers, 7 is a front cover, 8 is an upper cover, and 9 is a cross rail. It is a shielding member in which the partition wall part 9a and the hammer part 9b are integrally separated by +1, and the shielding member 9 is the opening warp between the reed 1 and the heald 2 with the hammer part 9b on the reed 1 side as shown in the first figure. It is provided directly above 3. Then, weft insertion is performed by a nozzle (not shown), and when the wet reed 1 swings toward the heald side after finishing weft beating, the water adhering to the reed 1 is removed by centripetal force in the direction of the partition wall 9a of the shielding member 9. I'll shake it up,
The partition wall portion 9a captures the scattered water and causes it to fall onto the hammer portion 9b. The hammer part 9bK is provided with a hole H at the bottom as shown in FIG. 2 and a notch N in the 1tll wall as shown in FIG. As a result, more water captured by the partition wall portion 9a falls onto the warp yarns 3 as the side toward the nozzle increases. As a result, the warp threads 3 are uniformly wetted on both the nozzle side and the anti-nozzle side, and the warp threads 3
Even if the oil falls off, it is easily washed away with water, and the oil is prevented from adhering to the liquid state of the reed 1 or the heald 2 in the form of highly viscous sludge or rubber.

The scenery of the scattered water captured by the partition wall 9a is distributed as shown in Fig. 4 in the frame width direction, and the amount of scattered water towards the fabric side is distributed as shown in Fig. 5.
It is distributed as shown in the figure. 4 and 5, 0 on the horizontal axis is the liquid end on the nozzle side, the reed passing width is 134α, and the reed width is 162
cm, 100 by injecting 2 cc of water into one weft insertion J1
These are the results of capturing and measuring the amount of scattered water when zero weft insertion was performed, and the total amount of captured water in Figure 4 was 535 cc, and that in Figure 5 was 293 cc. The distribution of Figure 5 with!
This shows the wetting condition of the warp threads in a conventional water jet loom.For this reason, more viscous oil sticks to the liquid and healds on the nozzle side, which is less wet, causing warp threads, warp knitting, or warp threads to become wet. I left the cut etc. However, since more water is scattered in the direction of the partition wall 9a than in the direction of the woven cloth, if this water is used to supply more of the water to the warp threads on the nozzle side, the warp threads of the entire width can be spread evenly. Kg, thereby preventing highly viscous oil from adhering to the liquid or the heald. The above-mentioned present invention has achieved this.

The present invention is not limited to the illustrated example, and the partition wall part and the gutter member may be separate bodies, and the means for causing more water to fall onto the warp threads than on the nozzle side of the gutter member may be, for example, This may be done by changing the distribution of the number of holes, by using holes and notches together, or by tilting the gutter member to change the head. They may be brought into contact with each other. When the warp threads are brought into contact with the gutter member, a sponge with continuous pores in which the pores are distributed larger toward the nozzle side can also be used as the gutter member.

〔Effect of the invention〕

According to the water jet loom of the present invention, even if non-sizing, non-twisted threads with oil applied to the warp threads are used, highly viscous oil is prevented from adhering to the liquid state and healds, and the warp meridian Excellent effects such as significantly eliminating warp warp and fluffing are obtained.
