Description

The improved lubricator that is used for textile machinery

Technical field

The present invention relates to a kind of textile machinery-lubricator (Oeler), it is particularly useful for knitting machine, for example circular knitting machine or flat pin knitting machine.

Background technology

Knitting machine and other textile machinery need lubricator mostly, so that be the part (for example knitting needle, sinker etc.) that the moves supplying lubricating oil film that is in operation.Lubricant is supplied with and must be come dispensing carefully, the pollution that is caused by lubricant with the textiles of avoiding manufacturing.Excessive lubricant is supplied with as not enough lubricant is supplied with and equally not too can be accepted, and it causes inappropriate wearing and tearing.

Mostly the device handled of application of compressed air is as textile machinery-lubricator, like it for example from known file DE 30 28 125 C2.The lubricator of explanation has the fuel tank that is under the pressure there.In fuel tank, be provided with the sprayer device that is used to produce mist of oil, mist of oil passes connecting pipeline and is blown the lubricant housings to knitting machine as air-oil mixture.Be provided with nozzle in order to produce mist of oil, it produces the fuel spray of general conical.In most of forms of implementation be provided with above the nozzle core drilling, be arranged in the axle journal on the wheel rim, it holds mist of oil.Nozzle is arranged to canyon ground in a different form of implementation, and axle journal is arranged in this nozzle.The end face of axle journal is smaller, makes it only hold less mist of oil.However, on the corresponding end face of axle journal or at its place, can form oil and gather thing (Oelansammlung), it can be spread the pipeline that is used for oil and air sometimes.When oil gathered thing arrival lubricant housings, this can cause overlubricate.When in order to reduce compressed air consumption and to come work with low air pressure and little air supply, this phenomenon is outstanding especially.

Summary of the invention

The purpose of this invention is to provide a kind of improved lubricator.This purpose utilization realizes according to the lubricator of claim 1:

Preferably have the sprayer device that is used to produce mist of oil according to lubricator of the present invention to canyon, and the oil trap acquisition means, it is arranged in the sprayer device below.The oil trap acquisition means has outlet, and pipeline leads to the lubricant housings from outlet, so that supply with gas mixture to it.

Be arranged in the sprayer device below through the oil trap acquisition means, the oily sediment that in the oil trap acquisition means, forms is directed in the pipeline that leads to the lubricant housings continuously.Oil long gathered and gathered thing (it can be spread in the pipeline sometimes) with the therefore bigger oil of structure and avoided.Guarantee uniform fuel feeding with this mode to the lubricant housings.

This is especially having the in service suitable of fluctuation and low especially compressed air volume flow.Need compressed air for the operation of sprayer device and for the spraying of oil.Here make and to deal with low-down air supply according to design of the present invention.Secondary part is played the part of in pressure oscillation (it can cause the variation of the drop size in the mist of oil).The mist of oil that is produced is certain to run into the oil trap acquisition means that is arranged in the sprayer device below.Mist of oil and the possible oily sediment that forms at the capturing device place can be transported to the lubricant housings therefrom.

Oil trap collection bag is corresponding to have cross section, and it is preferably more than the cross section of the pipeline that is connected.The bag cross section is measured transverse to bag-through-flow direction.It is at least greater than the flow cross section of the pipeline that is connected, yet is preferably more than the outer cross of pipeline to be connected.In a preferred form of implementation, described before corresponding suitable about (a plurality of) pipeline that is used for oil and air.Through the big capture cross section (it is arranged preferably as wheel rim and it preferably occupies the anchor ring of sealing at this) of oil trap collection bag, each oil trap collection bag hold that time that mist of oil sprays the mist of oil of cone (Spruehkegel) goes up and the space on average share.Mist of oil sprays scrambling and the fluctuation in the cone and/or on the capture cross section of the variation aspect droplet size and the density at the oil mist trapping bag, on average and is thus causing average formation aspect the oil mass that is captured.But this causes the oil stream of uniform fine correction in the pipeline of deriving.Can in the compressed air consumption of minimum, design sprayer device with this mode.It can move in an operating point, and it has not only produced very thin mist of oil but also has produced (taper or the conical hollow) beam that has the different size oil droplet therein.Such operating point considerably less compressed air mostly capable of using flows and also utilizes low air pressure to reach.

Preferably, not only sprayer device but also capturing device are arranged within the fuel tank of outer closure, also can have oil deposit (Oelvorrat) therein.Preferably, fuel tank is under the pressure that improves with respect to environment, so that mist of oil is come out to be delivered to the lubricant housings from fuel tank.

Textile machinery-lubricator is provided preferably with the compressed air interface, and compressed air can be directed to fuel tank and can on another path, guide to sprayer device on the path of the pressure pad (Druckpolster) that is used for setting up via it.Compressed air imports in the fuel tank and preferably takes place via adjusting or regulator, is lower than the compressed-air actuated pressure that is in the sprayer device place to guarantee the pressure in fuel tank.Yet because the beam under the sensing of sprayer device and the big oil trap collection cross section of oil trap collection bag also only need low relatively pressure at the sprayer device place.

Sprayer device is preferably according to the jet pump principle work, so that produce mist of oil.Jet pump can be directly from the oil deposit of fuel tank or oil suction from centre deposit (it comes out to be filled continuously from fuel tank) in other version, so that for the constant suction head of operation assurance of jet pump.

The oil trap acquisition means preferably has the coaxial passage that opens wide in the sprayer device orientation, and its wheel rim by oil trap collection bag centers on.Oil trap collection bag it top, in the face of the edge that place, the side of sprayer device has narrow seamed edge formula, do not have that oil gathers thing, especially oil droplet can keep above that.The oil that on the wall of oil trap collection bag, precipitates inwardly moves to the pipeline that leaves, and perhaps it outwards flows out and therefore turns back in oily the deposit.Because gathering the trend of thing, the interim oil of structure reduces the extremely little air capacity work capable of using of the rose of sprayer device.Do not exist as blowing the needs that similar oil gathers thing always off, because it for example flows out downwards through the central opening of oil trap acquisition means voluntarily.
