Description
The present invention relates to the feeding means of Sewing machines, more particularly, be with the sort of can be often that an amount of lubricating oil is supplied with the Sewing machines feeding means of slipper of Sewing machines is relevant.
Fig. 4 is the oblique view of structure of the feeding means of the Sewing machines before the expression, P is a pump among the figure, this pump is connected with the lower shaft 1 of Sewing machines M, can be when lower shaft 1 revolution, i.e. action when Sewing machines drives, the lubricating oil of oil-bearing structure's (food tray) lining of not representing among the figure is sucted, and this lubricating oil is exported from sending mouthful Pa.
The 2nd, by the oil content fitting mechanism that pipeline is connected with pump P, this oil content fitting mechanism 2 can have as shown in the figure two 2a of outflow portion, 2b in distribution of lubrication oil to two pipeline of pump P output.
And the lubricating oil that is distributed by this oil content fitting mechanism 2 is transported to the above and below of Sewing machines M respectively by petroleum pipeline x and y.
Below, the effect that is transported to the lubricating oil of Sewing machines top by petroleum pipeline y is described.
Be sent to the barrel member 7 that is provided with tap hole 7a from pump P by the lubricating oil in the petroleum pipeline y, flow out and be accumulated in 8 li of oil storage plates being located at Sewing machines M top from the tap hole 7a of this barrel member 7.Near this oil storage plate 8 through hole place that forms, end thereon has return duct 8a, and at ordinary times, the lubricating oil that transports from pump P flows to oil-bearing structure by this return duct 8a superfluously, thereby can guarantee certain lubricants capacity.
And oil storage plate 8 is connected by pipe 9 and known oil on the spudger 5 that the is arranged on Sewing machines member 6 that disperses, disperse lubricating oil that member 6 makes oil storage plate 8 towards the spudger 5 that is arranged on the Sewing machines head by this oil, needle bar 10 slippers such as grade disperse, thereby lubricating oil is supplied with each slipper.
The 11st, the lubricating oil that remains in the Sewing machines head during to each slipper fuel feeding at the member 6 that dispersed by oil that oil return pipe, this oil return pipe can make that felt 11a absorbs is back in the oil-bearing structure of Sewing machines.
On the other hand, be transported to the fuel control mechanism 3 of regulating the lubricating oil throughput, be transported to revolution shuttle 4 as the slipper of Sewing machines by this fuel control mechanism 3 by the lubricating oil of pump P by above-mentioned petroleum pipeline x.
As shown in Figure 5, this fuel control mechanism 3 is made of the saturating member 3a of oil immersion that is connected with revolution shuttle 4 and the 3b of the governor motion of the oily throughput variation that makes the saturating member 3a of this oil immersion.The saturating member of oil immersion contacts felt 3c by rotating shaft 4a following contacted with revolution shuttle 4 and wick 3d constitutes.Wick 3d is arranged between the petroleum pipeline x and contact felt 3c that is contained in the rubber tube.Governor motion 3b then by the adjustment screw 3e that can advance and retreat along wick 3d direction and be arranged on adjustment screw 3e and wick 3d between ball member 3f constitute.
This oily governor motion 3 changes the fastening force of wick 3d by making the positive and negative revolution of adjustment screw 3e through ball member 3f, and the oil of wick 3d is changed by resistance, thereby can regulate the oil mass of supplying with revolution shuttle 4.
But above-mentioned former Sewing machines feeding means has following problem.
Promptly because it is often forcibly the lubricants capacity of regulation to be flowed to fuel control mechanism 3 with pump P, thereby the problem that can not carry out micro-adjusting with 3 pairs of quantity delivereds of this fuel control mechanism is arranged.For example, even as reducing the oil mass of supplying with revolution shuttle 4, regulate fuel control mechanism 3, because pump P is force feed and adjusting fuel control mechanism 3 preceding identical oil masses still, fuel control mechanism 3 can not suitably suppress flowing of the lubricating oil sent here, therefore, also can all supply with the revolution shuttle to the lubricating oil of surplus.
Sewing machines must be regulated sewing speed according to sewn object, but because when regulating the sewing velocity of Sewing machines, the rotation speed change of lower shaft 1, the oily conveying capacity that makes pump P is respective change also, thereby the problem that can not become the fuel-flow control of supplying with revolution shuttle 4 suitable amount by fuel control mechanism 3 is arranged.For example, when the low-speed running that changes from per minute 160 when the rotating speed that makes lower shaft is varied to running up that per minute 3000 changes, the oil mass of sending is increased by pump, the result, the lubricating oil that surpasses the oil mass that needs all has been transported to revolution shuttle 4 by fuel control mechanism 3.
When superfluous lubricating oil being supplied with revolution shuttle 4, the sewing thread (bottom line) that is contained in the revolution shuttle 4 will be made dirty by lubricated oil, and the problem that sewing quality is descended is arranged as above saidly.
On the other hand, the feeding means of former Sewing machines also has and the above-mentioned different following problem of problem of superfluous lubricating oil being supplied with drive division.When for the upkeep operation that carries out Sewing machines the oil-bearing structure of Sewing machines being separated with pump P, air can enter into that c is when driving in the pump P, and pump P can flow to the revolution shuttle to this air that enters.
In addition, when pump P carries out high speed rotary, also can cause cavitation, make gassing in the lubricating oil thus, in this case, pump P also can be transported to the revolution shuttle to bubble (air), makes the fuel delivery deficiency of revolution shuttle, when revolution shuttle noticeable wear, just the problem that makes the wearing part corrosion is arranged.
Also, when Sewing machines drives again,, become the reason that the Sewing machines durability is reduced with regard to the problem that makes be in the state of lubricating oil deficiency revolution one time of shuttle is arranged because when Sewing machines was stopped for a long time, the lubricating oil that is transported to the revolution shuttle withdrawed from (adverse current) gradually.
The object of the present invention is to provide a kind of feeding means of Sewing machines; this device can only be supplied with drive part to the moderate lubrication oil of regulating according to fuel control mechanism, and can solve because air enters the problem of the drive part lubricating oil deficiency that causes when driving again after fuel control mechanism or the shutdown for a long time.
To achieve these goals, the feeding means of Sewing machines provided by the invention has the lubricating oil storage member that is arranged on the sewing machine body below; The pump of lubricating oil from lubricating oil storage member output usefulness; The lubricating oil that is arranged between the slipper of pump and Sewing machines is supplied with oil circuit; That adjusting is used to the quantity delivered of above-mentioned slipper supplying lubricating oil, be arranged on above-mentioned lubricating oil and supply with fuel control mechanism on the oil circuit, it is characterized in that, be provided with a Fuel Tanking Unit that comes out from the supply of the lubricating oil between pump and fuel control mechanism oil circuit branch, its superfluous lubricating oil partial reflux that is used for pump is supplied with is to the lubricating oil storage member.
In foregoing invention, on Fuel Tanking Unit, have the lubricating oil tap, it is arranged on the position that is higher than above-mentioned fuel control mechanism; Fuel Tanking Unit then is by being arranged on the distributing pipe that couples together than the also high locational oil storage plate of fuel control mechanism with the top of this oil storage plate and above-mentioned oil circuit and being used for constituting deliver to the return duct that lubricating oil in the oil storage plate sends back to the oil-bearing structure of Sewing machines superfluously.
Because Sewing machines feeding means of the present invention uses Fuel Tanking Unit the oil-bearing structure of the partial reflux of the surplus of the lubricating oil of being supplied with by pump to Sewing machines, thereby can only supply with drive part to the moderate lubrication oil of regulating according to fuel control mechanism.
Pumping out under the occasion of air, this air is risen in oil circuit top connects the distributing pipe of pump and fuel control mechanism and emitting, thereby can avoid air is fed to fuel control mechanism, can often supply with drive part to an amount of oil to the outside.
Also owing to Fuel Tanking Unit can be transported to drive division to the lubricating oil of the surplus of being carried by pump, thereby can solve the problem of the lubricating oil deficiency of the drive part when Sewing machines drives again after Sewing machines stop gradually.
