Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a device for supplying a lubricant to a rapier band of a rapier loom.

[0002]

2. Description of the Related Art A rapier loom generally includes a lubricant supply device for supplying a lubricant such as oil mist to a rapier band. As one of this kind of lubricant supply device,
As described in Japanese Utility Model Publication No. 4-60582,
An air cylinder pump is used as a pump for delivering the lubricant, and compressed air from the compressed air source that compresses the atmosphere, that is, pressure air, is used for operating the lubricant delivery pump and for ejecting the lubricant from the nozzle to the rapier band. Used in common.

As in the conventional lubricant supply device, an air cylinder pump is used as the lubricant delivery pump, and the pressure air source is used as both the pressure source for the lubricant delivery pump and the pressure source for the lubricant ejection. And the pressure of the compressed or compressed air generated by the compressed air source must be sufficiently high. However, when the atmosphere is compressed, the content of moisture or invisible dust in the atmosphere increases in proportion to the compression ratio, so the compressed air supplied from the compressed air source becomes very dirty air. Therefore, the conventional lubricant supply device requires an air cleaning device such as an air filter or a micron filter.

When the pressure air source serves both as the pressure source for the lubricant delivery pump and the pressure source for the lubricant delivery, the space between the pressure air source and the lubricant delivery pump and between the pressure air source and the lubricant delivery pump. A pressure reducing valve for adjusting each pressure value must be arranged between the nozzle and the nozzle, and as a result, in the conventional lubricant supply device, an air purifying device is required, and the entire device is The configuration is complicated and requires a lot of trouble and time for maintenance.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to simplify a device and facilitate maintenance.

[0006]

A lubricant supply device of the present invention is
A dedicated electric pump for delivering the lubricant, and one or more nozzles for ejecting the lubricant delivered from the electric pump to the rapier band together with the air delivered from the exhaust port of the yarn end treatment blower provided in the rapier loom. Including and

According to the present invention, the pump for delivering the lubricant is an electric pump dedicated to the pump and the pressure source for injecting the lubricant is the yarn end treatment blower provided in the rapier loom. As a result, a pressure reducing valve or the like is not required, and as a result, the device is simplified and maintenance management becomes easy.

The lubricant delivered from the electric pump and the air delivered from the exhaust port of the yarn end treatment blower may be merged at the nozzle, or may be merged before reaching the nozzle. The lubricant may be jetted to the rapier band on any of the upper surface, the lower surface, the side surface, etc. of the rapier band.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG. 1, a lubricant supply device 10 has a lubricant tank 12 which stores a liquid lubricant, and a lubricant tank 12 which is constant during operation of a rapier loom. A timer 14 that outputs a drive command signal P every time, an electric pump 16 that supplies the drive command signal P to supply the lubricant in the tank 12 for a predetermined time, and a lubricant that is supplied from the electric pump. Distributor 20 that distributes to a plurality of pipes 18, blower 22 that acts as a pressurized air source for spraying lubricant, air supplied from blower through hose 24, and lubricant supplied through pipe 18 And a plurality of nozzles 26 for ejecting and toward the rapier band.

The blower 22 is a blower provided for a rapier loom and used for yarn end treatment. The rapier loom is shown in Figure 2.
As shown in FIG. 5, an opening is formed in a series of warp threads 30 by an opening device, a weft thread 32 is passed through the opening by a rapier head 34 connected to the tip of a rapier band, and the weft thread 32 inserted is pressed to the cloth fell by a reed 36. . The end portion of the weft yarn 32, which has been weft-inserted, is sucked and held in the intake port 38 of the blower for yarn end processing over several picks. The yarn end treatment blower sucks air from the intake port 38 while the loom is operating. The air sucked into the blower from the intake port 38 is passed through the dust treatment device to be cleaned and then discharged from the exhaust port.

In the present invention, the blower 2 for yarn end treatment
2 is used as a source of pressurized air for jetting the lubricant. Blower 2
The air discharged from No. 2 is supplied to each nozzle 26 via the hose 24, and is mixed with the lubricating oil supplied to each nozzle 26 from the distributor 20 via the pipe 18 in each nozzle 26.

The nozzle 26 is attached to a guide 42 for a rapier band 40, as shown in FIG.
In the illustrated example, the nozzles 26 are attached to the side portions of the guides 42 so that the mist-like lubricant is sprayed on both side surfaces of the rapier band 40 in the width direction. However, the nozzle 26 may be attached to the guide 42 so as to spray the lubricant only on one side surface in the width direction of the rapier band 40, or the nozzle 26 may be sprayed so as to spray the lubricant on the upper surface or the lower surface of the rapier band 40. May be attached to.

When the rapier loom is operating, the yarn end processing blower 22 is always operating. Therefore, the blower 22
Since the compressed air is constantly supplied to each nozzle 26 from, the low-pressure air of, for example, about 0.05 kgf / cm ² is constantly blown from each nozzle 26 to the rapier band 40.

Further, when the rapier loom is in operation, the timer 14 is constantly operating over time, and the drive command signal P which becomes the "H" level is constant for a fixed time, for example, a few seconds to a few seconds. The electric power is supplied from the timer 14 to the electric pump 16 every 10 to 60 minutes, for example. Therefore, the electric pump 16 operates while receiving the drive command signal P to suck the lubricant and send it to the distributor 20. The distributor 20 distributes the lubricant remaining in the distributor 20 to both pipes 18 each time the lubricant is delivered from the electric pump 16.

As a result, the lubricant remaining in each pipe 18 is pushed out to the nozzle 26 every time the electric pump 16 is operated and mixed with the air supplied from the blower 22 through the hose 24 to form a particulate state. Become rapier band 4
It is sprayed toward 0. As a result, the electric pump 16
A predetermined amount of, for example, 0.01 cc of lubricant is sprayed from the nozzle 26 to the revear band 40 every time the s.

When the rapier loom is stopped, the blower 22 and the timer 14 are stopped. The timer 14 stops the time counting operation while the rapier loom is stopped, but stores the time counting time until then. When the operation of the rapier loom is restarted, the lubricant supply device 10 operates as described above by the blower 22 and the timer 14 operating again.

According to the lubricant supply device 10, the pump for delivering the lubricant is the dedicated electric pump 16, and the pressure source for ejecting the lubricant is the blower 22 for yarn end treatment provided in the rapier loom. Therefore, a pressure reducing valve or the like becomes unnecessary. Also,
Since the air discharged from the yarn end treatment blower 22 is usually passed through the dust treatment device and has a low pressure, the air cleaning device for the air for jetting the lubricant is not required. As a result, according to the lubricant supply device, the overall configuration is simplified and the maintenance management is correspondingly facilitated.

The present invention is not limited to the above embodiment. For example, the lubricant and the air from the blower 22 may be fed to the nozzle 2
Instead of mixing at 6, mixing may be done before reaching the nozzle.
