Description

[Detailed Description of the Invention] This invention relates to a heald cleaning device in a heald cleaning device.

In general, in the case of a fluid jet loom, such as a water jet loom, water is jetted from a main nozzle, and weft insertion is performed by the jet of water. When this happens, the glue from the warp threads falls off, resulting in glue scum and fluff adhering to the heddles. Conventionally, in order to remove this glue scum and fluff, maintenance workers manually cleaned the fabric using pressurized water, a brush, etc. after the fabric was woven. However, as glue residue adheres and solidifies over a long period of time, it takes a lot of time to clean it, which not only makes maintenance work longer and more labor intensive, but also causes problems in terms of loom operation rate. It is.

This invention was proposed in view of this point of view, and it is possible to completely wash and remove glue scum, fluff, etc. that adhere to the healds during the operation of the loom, or at least shorten the cleaning work performed at the time of weaving. An object of the present invention is to provide a cleaning device for healds in a fluid jet loom.

That is, the gist of this invention is to inject cleaning water onto the heald at a predetermined timing during the operation of the loom.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The heddle cleaning device for a fluid jet loom according to the present invention will be described in more detail below with reference to the accompanying drawings.

As shown in the accompanying drawings, the heald cleaning device (hereinafter simply referred to as the "cleaning device") for a fluid jet loom of this invention has the following configuration.
That is, the heald frame 1 (1a, 1b, 1c, 1d) of the loom
A guide rail 4 is stretched at a position parallel to and spaced from the heald frame 1 on the rear side. The nozzle base 5 is attached to the guide rail 4.
A nozzle 7 is attached to the nozzle base 5 via a nozzle holder 6.
is installed. One end of a connection hose 15 is connected to the nozzle 7, the other end of which is connected to a cleaning liquid supply tank (not shown). Then, this hose 15 is wound into a coil shape and connected to the rod 13.
This prevents the hose 15 from hanging down.

A predetermined portion of a drive belt 8 is attached to the nozzle base 5, which is rotatably stretched between a pair of drive pulleys 9 (one not shown) installed on a head guide bracket F. and,
The drive pulley 9 is provided with a handle 10 mechanism for manually applying rotational force to the pulley 9. Therefore, when the handle 10 is turned, the drive belt 8 also rotates, and as a result, the nozzle 7 attached to the drive belt 8 via the nozzle holder 6 and the nozzle base 5
The heald frame also moves in the direction in which the heald frame extends in accordance with the direction of rotation of the handle 10. If cleaning liquid is sprayed from the nozzle 7 during this movement, since the tip of the nozzle 7 is set to face the heald frame, the sprayed cleaning liquid will remove glue scum and fluff that have adhered to the heald 2. Wash and remove. Of course, if you set the jet direction of this nozzle 7 freely,
The injection direction can also be changed if necessary. Note that the nozzle 7 needs to be located below the warp sheet. That is, above the warp sheet, glue scum and fluff washed off by the washing water may adhere to the warp threads, and if washing water is splashed onto the warp threads, fluff, etc. will occur on the warp threads, which is undesirable.

In the above description, the nozzle 7 is moved in the heald extending direction by operating the handle 10, but the invention is not limited thereto. That is, the drive pulley 9 may be rotated electrically. In addition, limit switches may be provided at predetermined positions on both ends of the guide rail 4, so that the nozzle 7 can be moved back and forth on the guide rail 4 while the loom is in operation.

Furthermore, if a water pressure increase/decrease adjustment valve is interposed in the hose 15 that connects the nozzle 7 and a cleaning liquid supply tank (not shown), the injection pressure emitted from the nozzle can be changed and set as appropriate. Alternatively, the cleaning liquid may be injected from the nozzle 7 intermittently by using a valve device that opens the valve intermittently.

According to this invention, the following effects can be obtained. That is, since it is possible to remove some stains on the healds due to adhesion of glue scum and fluff during weaving, the warp threads are not damaged or soiled during weaving. Furthermore, since cleaning liquid is sprayed onto the healds during weaving to keep the healds in a moist state, it is easy to remove glue scum and fluff that adhere to the healds during the weaving process, reducing maintenance work time related to heald cleaning. This is preferable in terms of loom operating efficiency.
