Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heald cleaning device that is attached to a loom and performs a shedding operation on warp threads.

Generally, in a loom, the warp threads are inserted into the warp insertion holes of the heddle and the heald is moved up and down to cause the warp threads to perform a shedding operation. FIG. 1 shows the state in which the heald is attached, and 1 is the heald, 2 is a warp thread insertion hole provided in the center, 3 is a heald bar, and 4 is a heald frame.

During weaving, the glue applied to the warp threads adheres to the vicinity of the warp insertion hole 2 of the heald 1 as the warp threads open and move. In a loom using a shuttle, this glue was only in the form of fine powder and adhered to the heald 1, so it was easy to clean and remove it. However, in the water jet loom, due to the weft insertion mechanism, the area around the heald becomes wet, and the glue adheres to the heald together with water, solidifies into a resin, and firmly adheres to the heald 1. Since the speed is high, the amount of glue deposited is large, which impedes smooth weaving operation, making it necessary to remove the heald 1 along with the heald bar 3 and clean it at regular intervals.

Conventionally, the heald 1 to be cleaned was immersed in a heated caustic soda solution and then the heald was cleaned manually, but this work required a great deal of effort and was extremely hard work. Furthermore, an apparatus is known that cleans the heald 1 while it is suspended on a carrier, but this apparatus has the problem of being large-sized and having poor working efficiency.

SUMMARY OF THE PRESENT EMBODIMENT The present invention has been made with an object of providing an apparatus which can efficiently wash healds with a simple operation.

Figures 2 to 7 show an embodiment of the present invention, with Figure 2 being a side view showing the frame structure, and Figure 3 being a side view showing the drive system of the heald and rotating brush. .

In Figure 2, 5 is the lower frame, 6 is the upper frame, 7
8 and 9 are guide rails fixed to the upper surface of the lower frame 5, and 8 and 9 are attached to the lower frame 5 by bearings 10 and 11.

The heald 1 to be cleaned is inserted between the lower frame 5 and the upper frame 6 along the guide rail 7, and is sent by the chain 17 from left to right in the figure while being conveyed by the rotating brushes 8, 9 and 12, 13. Its upper and lower surfaces are rubbed in a direction opposite to the direction of movement to clean it. As shown in FIGS. 4 and 5, the guide rail 7 is comprised of a channel having a U-shaped cross section, and a longitudinal groove 21 is provided on its upper surface. On the other hand, pins 22...22 are implanted at predetermined intervals in the chain 17, which is arranged to move directly under the guide rail 7. Both ends of the heald bar 3 of the inserted heald 1 are engaged with the pin 22, and the heald 1 is conveyed by the chain 17. This type of heald transport mechanism is also located on the other side of the diagram.
Both are driven simultaneously by an electric motor, which will be described later.

The upper frame 6 has one lower end pivotally connected to the lower frame 5 by a pin 23 so as to be openable and closable, and is fastened to the lower frame 5 by a locking tool 24 provided on the other side during cleaning of the heald 1. . The reason why the upper frame 6 can be opened and closed is so that when trouble occurs during cleaning of the heald 1, the passage of the heald can be opened and the trouble can be easily solved. 25
is a hook used when opening the upper frame 6. 26 and 27 are legs 28 and 2 of the lower frame 5

As shown in FIG. 4, the ends 8a and 9a of the rotating brushes 8 and 9 will interfere with the guide rail 7, so it is necessary to provide a notch in the guide rail 7 to avoid this. be.

Similarly, 34 and 35 are the horizontal members of the upper frame 6,
A handle 36,
Screw rods 38 and 39 having a diameter of 37 are rotatably installed, and a bar 40 to which the rotating brushes 12 and 13 are pivoted is screwed onto the screw rods 38 and 39 at both ends and is mounted so as to be able to move up and down. . At the center of the horizontal member 35 above the upper frame 6, an elongated water sprinkling pipe 41 extending toward the other side of the figure is attached, and water is sprayed from this water sprinkling pipe during heald cleaning.

Next, the drive mechanism for the chain 17 and the rotating brushes 8, 9, 12, 13 will be described in detail based on FIG.

42, 43, 44, 45 are sprockets for tensioning the chain 17, 46 is an electric motor for driving the chain, 47 is a reversible transmission connected to the electric motor 46, and 48 is for adjusting the tension of the chain 17. These devices constitute a chain drive mechanism 18.

Next, 49 is an electric motor for driving the rotating brushes 8 and 9 attached to the lower frame 5 in the direction of the arrow;
50 is a transmission connected to the electric motor 49, 51,5
2 is a pulley fixed to the shafts 53, 54 of the rotating brushes 8, 9; 55, 56 are belts stretched between the transmission 50 and the pulleys 51, 52; 57, 58 are tensions of the belts 55, 56; This is a tension idler for adjustment. These devices constitute a drive mechanism 19 for the rotating brushes 8 and 9.
Similarly, 59 is an electric motor for driving the rotating brushes 12 and 13 mounted on the upper frame 6, 60 is a transmission connected to the electric motor 59, and 61 and 62 are connected to the shafts 63 and 64 of the rotating brushes 12 and 13. Fixed pulleys 65 and 66 connect the transmission 60 and the pulley 6.
1,62, and 67,6
8 is a tension idler for adjusting the tension of belts 65 and 66. These devices constitute a drive mechanism 20 for the rotating brushes 12 and 13.

4 and 5 are partially enlarged views showing the conveyance state of the heald 1, in which the pin 22 provided on the chain 17 pushes the heald bar 3 on the guide rail 7, and the heald 1 is moved by the rotating brushes 8, 9. , 12, and 13 while being rubbed.

The chain 17 has a set of three pins 22a...22
a, 22b, . The rear heald bar 3b is engaged with the next set of pins 22b...22b. In this installed state, the heald 1 passes through the heald passage, and the upper and lower rotating brushes 8, 9, 12,
13, it will be rubbed and cleaned. The reason for this configuration is that during heald cleaning, the rotating brushes 8, 9, 12, and 13 apply a strong rubbing force in the direction opposite to the direction of movement of the heald, and it is necessary to stably hold the heald bar 3. Furthermore, after cleaning, it is necessary to push the heald 1 with the pin 22b to eject it from the guide rail 7.

6 and 7 illustrate the rotating brush used in the present invention, 69 is the base of the rotating brush, 70 is a metal fiber such as brass or stainless steel embedded in the base 69 in a cross shape. bristles consisting of rays,
Reference numeral 71 indicates bristles made of organic fibers such as hair, nylon, or pig hair, which are implanted in the base 69. The reason for this configuration is that a rotating brush made only of metal fibers would seriously damage the heald 1;
On the other hand, a rotating brush made only of organic fibers cannot remove the glue sufficiently.

Furthermore, as shown in FIG. 7, if bristles 70 made of metal fibers are provided in a spiral shape, fluctuations in the sliding force acting on the heald 1 can be avoided.

As described above, in the present invention, two guide rails 7 that guide both ends of the heald bar 3 are arranged substantially horizontally, a passage for the heald 1 is formed between the rails 7, and a water sprinkling pipe 16 is provided above the passage. An engaging member 22 is provided and engages with the end of the heald bar 3.
A heald feeding mechanism 17 is provided along the guide rail 7, and elongated cylindrical rotating brushes 8, 9, 1 are provided across the passage of the heald 1.
The heald 1 is moved in one direction along the rail 7 while spraying water from the sprinkler device 16, and the rotating brushes 8, 9, 12, and 13 are moved up and down. The feature is that the bristles 70, 71 are rubbed against the heald 1 by rotating in the opposite direction to the direction of movement, so that the heald 1 can be efficiently cleaned with a simple operation. .
