Direct splash lubricating system for knitting machine

Relevant application: this application claims and enjoy in U.S. Provisional Patent Application that December in 2013 submits on the 20th the The priority of No. No.61/919,184.

Technical field

The invention belongs to the field of the lubricating system for knitting machine, and be particularly useful for direct splash lubricating system, its Oil is sprayed onto or solid oil drop is projected on the knitting elements of knitting machine, and by the way of measuring and be controlled Lubricate this element.

Background technology

The particularly suitable machine of the present invention includes that single weaving machine, double jersey knitting machine, sweat shirt peace lead shirt pin Loom and the machine of many other needs the most periodically lubrications.Some example of currently used machine includes with trade (brand) name The machine that Mayer and Cie, Terrot, Fukuhara, Orizio, Vanguard, Pai Lung etc. sell.

Lubricating method for above-mentioned machine includes the solid drop pulse lubricator of good name lattice ultrasounds lubricator company With microdroplet impelling lubricator, and the oil mist lubricator/oil spray lubricator sold by Uniwave company of good name lattice branch.Attached Part A, B, C, D, D2 and E show some example of prior-art devices, which show various traditional knitting machine and for Its lubricating oil.

One of them system of these systems is passed through by plastic tube or other pipeline from multiple ports (up to 24 ports) Connect multiple nozzles and penetrate mist of oil/oil spout.This system uses electric power and compressed air, to form oil spout, and by oil with all Weigh stable flow distribution to each jet expansion.

Second system also with nozzle and pipeline by multiple ports injection per minute solid oil droplet pulse several times. This system only uses electric power, because need not compressed air to perform function.

These solid drops and mist of oil/oil jet lubrication system are respectively provided with unsatisfactory and/or amendatory feature.

(1) any system is impossible to provide oil spout and the two types of solid drop lubrication；And thus the most public In the case of component, small volume, and unit price is higher；

(2) two kinds of lubricating systems are all difficult to repair when occurring and blocking；

(3) Uniwave mist of oil/oil spray lubricator uses relatively great amount of compressed air, and it has the factory of a large amount of knitting machine In be fairly expensive；

(4) it is unpractiaca for using central authorities' oil supply source in such systems so that each unit needs himself fuel tank.

This has been the situation of at least six ten five years in the operation of knitting machine.

Approving in the sector, lubricant will not be evenly distributed on knitting elements by oil droplet pulse system.Though So spraying system achieves preferably oil distribution work, but they use relatively great amount of compressed air, and it has high energy Amount cost, and lubricant may be polluted by the water that compressed air system is intrinsic.

Although the sector appreciates some problem the most well, including: (a) spreads in the most knitting of factory's setting Near machine, the mist of oil in air and environment is dangerous for health and not pleasant, and may pollute or damage pin Together with fabric, dust in being likely to result in air with (b) or other particle agglutination, and drop on machine, floor and the person.

A kind of known scheme is to use lubricating system, and wherein oil/compressed air stream have employed protection from fumes nozzle, and it passes through Whirlwind makes oil again be condensed into microdroplet, rather than mist of oil.Which solve the mist of oil problem in environment, but add sizable one-tenth This.

Thus, the sector has had have been used more than 30 years but the scheme of costliness, and does not has known evidence just to show Built in problem is processed in any difference of research or less expensive method.My new invention is a kind of " directly injection " device, its There is the spraying of improvement and the feature of pulse system, decrease running cost simultaneously.

Summary of the invention

First purpose of new equipment is to provide spraying or the selection of impulse oil lubrication for end user, and can in office when Between, switch between both types of lubrications.

Another object is that when manufacturing two kinds of lubricator by utilizing common unit to reduce manufacturing cost.

Another object is that and allow that water, with this small amount of through system, causes less bad impact.

One extra purpose is to reduce for the manufacturing cost manufacturing " only pulse " model.

Another object is that and reduce the air supply for mist of oil/oil jet lubrication, and thus decrease running cost.

A further object is to provide a kind of practicable approach, to have the central lubricant source for multiple lubricators, Rather than there is compulsory single oil groove.

Another object is that and allow for spraying and a kind of bleed type of pulse lubrication use.New nozzle will compare current nozzle Cheap.

If a further object is when repair is needed and needs to repair, allow and carry out being easier to and less expensive repairing.

Another object is that efficiency and the earning rate improving operation, including cost and the operating of device and utilize this device The operating of factory.

Another object is to provide device, and it can use wider array of different lubricant, including the lubricant class with emulsifying agent Type, tends to form blocking when by moisture contamination.This will allow for lubricant and is easier to remove from fabric.

New " directly injection " system (being referred to as " directly injection " system in the present patent application) can be held by a unit Row two functions above-mentioned.That is, each output is probably mist of oil/oil spout or solid oil droplet, and this depends on nozzle and pipeline Configuration.

Directly injection lubricator is allowed being less prone to from compressed-air actuated water and the lubrication in spraying/mist of oil pattern Oil phase mixes.

In only impulse model, direct injection unit will be cheaper than current PRF unit making.

When using central authorities' oil sources for multiple lubricators, direct spraying system will be the compactest, and may be installed ratio currently In the space that system (not having single fuel tank to supply on unit) is less.

The present invention pulse lubrication is used by avoid with spray pattern lubricate in compressed air be associated for greatly Compressed air volume and the demand of big cost of energy.Or, the use under spray pattern will provide lubricant when needed Be uniformly distributed.When buying with only pulse protocol, new unit will be that manufacture is cheap.Due to the simplicity of design, new Unit will need less maintenance, and be easier to when needs are repaired repair.

This new lubricating system may make up many configurations.Most important four will is that

1. lubricator, it can spray oil from each nozzle of its multiple nozzles or release the pressure-actuated oil droplet of solid.Respectively It is as the same that individual output can be changed to pulse or vice versa by simply changing the configuration of plastic tube from spraying, and plastic tube is from " oily hair Raw device " extend to delivery nozzle.Owing to output is penetrated, under stress so lubricant will advance the most some English from nozzle Very little；

2. lubricator, it can only discharge solid oil droplet；

The most any of the above lubricator can receive its fuel feeding from the independent oil groove of himself, or receives supply from central source, Central source can be supplied to multiple unit, thus eliminates the demand for independent oil groove；

4. each nozzle will have particularly design, and it will allow for the use of wide variety of viscosity.By by air pressure from 2 pounds/square inch (PSI) adjusts to 10PSI or bigger, thus can use lower viscosity and the lubricant of more high viscosity.Due to Being specifically designed of nozzle, nozzle will allow for mist of oil and penetrates oily some inches from top, without causing waste oil at exit point Lower.That particularly " without lower " design is about 0.020 inch due to the endoporus (hole) of nozzle (axial inner on top) Diameter, and the hole of nozzle tip about 0.040 inch diameter and complete its task.This identical nozzle also will allow for Pulse modulated solid oil droplet leaves nozzle rightly, and does not drip under exit point generation oil.

In spray pattern, the oil of pressurization inputs or obtains supply by central source or the oil groove of pressurization of pressurization. When using independent oil groove model, the compressed air of filtration will provide power for fuel tank pressurization.Oil output is by by electromagnetic valve Controlling, it is controlled by pulser timer, and pulser timer may be set to for the most per minute that to open valve some Secondary, this depends on which type of output volume of needs.In the oil pressure regulator subsequently into band scale, thus can be by oil pressure It is set as the oil pressure that operator prefers.In the oil grease chamber subsequently into " directly injection oil generator ", it is as shown in FIG. It is labeled as directly spraying oil generator.

In order to be more fully understood that the term for the present invention, " smog " is oil, and its drop is too small so that in the environment and stops Staying in the air, rather than attachment is on the metal surface, and " mist of oil " is elaioleucite, it is so large that, makes them be attached to solid On facility, and will not become airborne.In embodiment disclosed herein, as shown in Figure 2, oil groove is placed on air After actuator and before timing electromagnetic valve.Nozzle is the terminal of this system, and it is devoted to there is knitting machine part to be lubricated.Fall Hook is the soft part of flexible pipe, and its near-end is assemblied in the top of generator, and its far-end engages with nozzle.

When the oily pulse of pressurization is discharged by electromagnetic valve, oil is forced to rise in the pipe on top, grease chamber.These metal grease chambeies Outlet has one-way non-return ball so that the oil of injection can not return in grease chamber.In the exit of pipe, oil passes through compressed air (air pressure advised in this is 2 to 5PSI) is attached, and compressed air is supplied by the air chamber of oil generator, And leave from the inside of outer barb, and causing oil/compressed air mixture through plastic tube, plastic tube is arranged on bigger outside The outside of barb and final nozzle (see the jet exit of labelling and directly injection oil generator and nozzle in figure).In directly spray Penetrating the oil pressure of suggestion at grease chamber is about 10PSI.If operator wishes that any or all nozzle is impulse oil rather than oil spout, So have been placed in the plastic tube in external barbs and be replaced by the plastic tube being arranged on grease chamber's pipe interior.This inside is moulded Material pipe also serves as sealing member, to block compressed-air actuated escape.

Directly " only pulse " model of injection lubricator is identical with oil spout, but eliminates filter, serpentine pipe and sky Gas actuator, it is for preparing the compressed air of the air chamber leading to oil generator.Directly splash lubricating system can be used for needing meter Measure constant oil jet lubrication or any application of solid oil droplet lubrication, such as gear, chain, automatic elevator, oil well rig, weave cotton cloth Machine etc..

Detailed description of the invention

Figure 1A show schematically show factory floor plane 1, and it includes multiple knitting machine 2, and knitting machine 2 passes through air line 4 and by from the compressed-air actuated supply of compressor 3.Also schematically shows grease chamber 5 in figure, it is for by required Oil is supplied to each knitting machine 2.

Figure 1B show schematically show feed lubrication device 5, and it has multiple injection pipe 6, and each injection pipe terminates in nozzle 7 In.

Fig. 1 C shows the flow chart of the oil spray lubricator 10 for the present invention, and it includes the compressed air of about 90PSI Source 12, this air generally includes the water of certain percentage.Compressed air flows through filter 14, with cleaning compressed air, and reduces The water yield of the inside.Next compressed air flows to electromagnetic control valve 16, and electromagnetic control valve 16 is on-off valve, every subsystem effectively When lubrication oil spout being guided to knitting machine element, turn on on-off valve.Air overregulates device 18, actuator from spiral pipe flow The air pressure of initial about 90PSI is reduced to 2-10PSI by 18, or preferably 2-5 PSI sometimes, and it depends on selected Operating parameter.Next this air stream advance in oil generator 20.

In this system also from the oil in source 22, it is usually from single oil groove, as seen in Figure 2, or comes Central source from about 5 or bigger PSI.Oil is flowed in actuator 24, and herein, pressure subtracts from described about 5 or bigger PSI Few to preferably operating pressure, flow to the pulser timer 26,28 of Electromagnetically-operating, its injection the most per minute afterwards 5 times (every 12 seconds once) of oil, opens in a flash, the most about 2/10 or 3/10 second the most every time.It is flowed into oily hair the most afterwards In raw device, it combines with the air of actuator 18 input herein, and is penetrated as oil spout (told by multiple outlet nozzles 29 Go out), as described further below.

Fig. 2 show schematically show solid oil droplet lubricator 30, and it is partly different from the oil spout described in above figure 1C Lubricator 10, because its compressed air input not mixed with oil.Therefore have from source 22S's after actuator 24S Oil, then flows to pulser timer 26S, the 28S of Electromagnetically-operating, finally flows to oil generator 30S and its delivery nozzle 32S.

The generator 30S in oily generator 20 and Fig. 2 in Fig. 1 C shares public characteristic, but the generator 20 in Fig. 1 C will Oil mixes with compressed air, as described further below.Fig. 3 show schematically show directly injection oil generator 40, its It is available for oil spray lubricator or solid oil droplet lubricator uses.

In figure 3, have in shell 42 and be positioned at the oil-in 44 of bottom, it is provided that the oil of about 10PSI, this generally with Corresponding from the oil phase of the actuator 24 in Fig. 1 C.Under being in the shell 42 of oil generator 40, basis 46(is here because of it Configuration and be referred to as " basic "), intermediate base 48 and upper basic 50, wherein grease chamber 52 is correspondingly limited at lower basis and centre Between basis 46 and 48；Basis may be additionally referred to as interval or wall.Being positioned at above intermediate base 48 is air intake 54 (itself and figure The air stream flowing out actuator 18 in 1C is corresponding), in the air chamber 56 that it is flowed in Fig. 3, or it is fed directly to air line, I.e. surround in the annular space of oil pipe 58.Oil from the grease chamber 52 in Fig. 3 is flowed in the pipe 58 with outlet 58a, and enters The air flows upwards of air inlet chamber 56 also flows out the annular space 60 surrounding oil flow tube 58.As will be it is further described that flow out each The oil stream of pipe 58 has been pulse modulation into drop-wise form (as mentioned above for described in Fig. 1 C and 2), and it outwards separates, simultaneously at ring Having the air stream of tubulose in shape space 60, it surrounds and carries this microdroplet to each outlet nozzle, such as institute further below State.It is described later lower basis, intermediate base and upper basic 46,48.

Fig. 4 shows oil and air flow duct, and it extends out from the oily generator of Fig. 3.Fig. 7 shows nozzle 82, It is positioned at the top of telescoping tube 90, thus is connected on outlet air and the oil-piping of Fig. 4, and they go out with Fig. 3 top Mouth is corresponding.Fig. 4 shows jet exit 70 as enlarged drawing, and it includes the little central oil pipe 72 of band medium pore 73, and it will Oil 75 carries to nozzle 82, sees Fig. 7.Surround inner tube 72 is outer space trachea 76, has between said inner tube 72 and outer tube 76 Annular space 60.This annular space 60 sees in Fig. 3 earlier.As noted earlier, annular space 60 is voltage supply stream of compressed air mistake Flow channel.In the diagram, the outer surface of outer tube 76 being barb 80, it connects for being fixed on by this outlet duct apparatus 76 90 include outlet 76 and lead to the end of nozzle 82.Barb 80 is typically disk or the packing ring of inclination, and it rubs and close Feud engages with the hole surface of the plastic tube that they insert.As seen in Figure 3, four joints 290 have it on outer tube 76 The lower end slided engagement barbs 80.Nozzle 82 has nozzle barb 94, and it upper end with junction block 90 engages hermetically.

Fig. 3 shows two kinds of single emptying patterns: three outlet groups indicated by the left side I, II and III in (a) figure Part provides air/oil spout；(B) the right outer tube assembly indicated by IV provides only oil droplet, because air stream is the most blocked ?.For the outlet of right side impulse oil pattern, the lower end 90L of plastic tube 90 is positioned in annular space 60, to block air stream, makes Oil must be only had to be penetrated by nozzle 82.Thus, this oil generator can be according to the I on the left of this figure under fuel injection mode, II or III Shown in nozzle connect, or connect according to nozzle shown in IV on the right side of this figure under solid oil droplet pattern and operate. Operator may select all nozzles of generator and is located at fuel injection mode, or all nozzles are located at oil droplet pattern or its some group Close.Thus, the single generator design with its nozzle can be used for various situation, such as, for cotton yarn, operator may preferred arteries and veins Rush oil droplet, to save expensive compressed-air actuated use, or oil spout preferred for nylon yarn, to avoid textile dyeing.

Fig. 5 provides basic 50, intermediate base 48 and the plan view from above of the lower amplification of basic 46.Described three bases It is respectively provided with the form of the disk being cannulated with various hole, and each described basis is sealed by O.Locking snap ring 46R and 50R will Lower basis and upper basis are fixed in shell.

Now turn to Fig. 5, upper basis and intermediate base 50 and 48 and there is identical pass formula, positioned by it and support ten Four pipe 50P, it is the most as shown in Figure 3.For the oil pipe of other quantity, pass formula alternately is feasible.Base foundation 46 Having medium pore 46A, it is threaded, to receive oil inlet pipe, as seen in Figure 3.Basis 48 and 46 is inserted upwardly into shoulder, And be stapled 46A and fix；Basis 50 is downwardly into shoulder and is fixed by its lock ring 50R.

Fig. 6 is the front view of the amplification of the intermediate base 48 shown in Fig. 3 and a typical oil flow tube 58.Pipe 58 includes One way stop peturn valve 62, it allows oily to upstream, and hinders any reverse flowing downward.For the sake of facility and description, this In disclosed embodiment have employed word " upper and lower "；But oil generator is not limited to this orientation.

When oil droplet penetrates in a pulsed fashion from inner tube 58, this oil droplet is coupled together by air stream, through the ring in Fig. 3 Annular space 78 in shape space 60 or Fig. 4, air oil mixture outwards penetrates.Junction block 90 prolongs along the external diameter of outer tube 76 Stretch.By the pipe 72 in Fig. 4, the air stream of the annular space 78 between 78 will blow oil droplet, until it arrives its nozzle, and penetrate Go out in knitting machine element.

Oil droplet from inner tube 78 is blowed by the air of the very low pressure of the most about 2 to 5PSI.This low-pressure Oil decomposition will not be made to become mist of oil, because this air has laminar flow along the medial wall of plastic tube, until it arrives nozzle, and From nozzle, air/oil mixture is injected to machine part to be lubricated, all without forming mist of oil.This is the present invention One of Main Achievements.

If outlet nozzle receives air/oil mixture or solid oil from its plastic feeder conduit, it will be grasped rightly Making, plastic feeder conduit extends at the top of directly injection oil generator or oil spray lubricator.If nozzle receives solid oil, then It will be at pulse cycle time discharge microdroplet.If nozzle receives air/oil mixture, its oil that will spue by this way, i.e. This output is spued from the some inchs of nozzle by it, and does not has under oil to drop on nozzle, and does not has any oil decomposition to become smog. The entrance of oil arrival nozzle is as undecomposed solid oil, and will eject uninterruptedly in this arrangement, and Being formed without oil fume, it may pollute the surrounding in factory.

And the additional features of the present invention relates to the top form of outlet nozzle.When oil arrives by straight (filled aperature) shape During the top of conventional spout become, it is possibly blown into mist of oil, and/or causes lower, rather than with required oil droplet form Spued regularly.In nozzle new seen by Fig. 7, nozzle 82 have aperture Dl (about 0.030 ", but can change to greatly Diameter much), it reduces to diameter D2 (about 0.020 inch), and is extended to diameter D3 (about 0.040 English on top Very little).D3 part has length L3 (about 0.125 ", but may be longer)；D2 adds D3 part and has the length of (about 0.125 inch) Degree.The air stream carrying oil droplet from there will be expanded to relatively low pressure slightly in D3 part so that oil will opposing nozzle top Lower of end, and droplet form will be kept.As noted earlier, pressure declines between D2 and D3 diameter portion.It addition, as above institute Stating, this is a significant achievement, thus avoids oil from of nozzle and the negative consequences of the lubricant of waste costliness.

The present invention has carried out presenting and being shown in a preferred embodiment in terms of concept；But, at this In invention concept here, variant may be expected by those of skill in the art.
