By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present invention and effect easily.
Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, still all should drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
In the present invention, all directions are defined as follows: the length direction of baseplate of sewing machine 1 is fore-and-aft direction; The width of baseplate of sewing machine 1 is left and right directions, and the thickness direction of baseplate of sewing machine 1 is above-below direction; Or, as shown in Figure 1, in Fig. 1 X-direction to be front to, U direction be rear to, T direction is left direction, and Y-direction is right direction, and Z-direction is upper direction, and W direction is lower direction.
As shown in Figure 1 to Figure 3, the invention provides a kind of peg or spindle automatic coiling device, the base plate 1 comprising Sewing machines and the support 2 be fixed on front side of base plate 1, the below of described base plate 1 is provided with a rotating roll 3, described roll 3 is provided with an axle portion 301, in this axle portion 301, cover has peg or spindle 15 and axle portion 301 is tight fit with peg or spindle 15, thus realizes removably connecting of axle portion 301 and peg or spindle 15; The front side of described support 2 is provided with a thread clamping mechanism that can rotate around peg or spindle 15, and this thread clamping mechanism is for clamping the bottom line 29 be wound around on online cylinder.
The present invention also provides a kind of peg or spindle automatic winding method, comprises peg or spindle automatic coiling device as above, and described peg or spindle automatic winding method in turn includes the following steps:
A, peg or spindle 15 is enclosed within the axle portion 301 of roll 3;
B, thread clamping mechanism clamp the bottom line 29 be wound around on online cylinder;
C, thread clamping mechanism rotate N circle around peg or spindle 15, N circle on wrapping post bottom line 29 being wrapped in peg or spindle 15;
D, thread clamping mechanism unclamp bottom line 29;
E, roll 3 rotate, and drive peg or spindle 15 to rotate together, until the wrapping post of peg or spindle 15 is wound around full bottom line 29.
Preferably, as shown in Figure 7, the rear side in described axle portion 301 is provided with a bulge loop 302, for limiting moving backward of peg or spindle 15, on described roll 3, also radial direction offers a groove 303, the front end of this groove 303 extends to forward the front end place of roll 3, the rear end of groove 303 at least extands rearward to the rear end in axle portion 301, described groove 303 makes the fore-end of roll 3 be made up of two semiaxis, and between two semiaxis, have the space of relative motion, therefore when peg or spindle 15 is enclosed within roll 3, there is elasticity, so that the loading of peg or spindle 15, and after in the axle portion 301 that peg or spindle 15 is enclosed within roll 3, the tensile force between peg or spindle 15 and axle portion 301 can also be improved, to ensure the reliability be connected between peg or spindle 15 with axle portion 301.The structure of described peg or spindle 15 belongs to prior art, and generally speaking, peg or spindle 15 comprises wrapping post and is located at the flange at wrapping post two ends, for being wound around bottom line 29 on described wrapping post.
In the present invention, described thread clamping mechanism can do spatial movement around peg or spindle 15, because the inner space of Sewing machines is very limited, in order to make apparatus structure compacter, more preferably, as shown in Figure 1 to Figure 3, also comprise one rotatable and can before and after the pivoted arm 6 that moves axially, this pivoted arm 6 is positioned at the front side of support 2, and the rear side of described pivoted arm 6 is provided with a rotating oscillating deck 8, and described thread clamping mechanism is fixed on oscillating deck 8.Pivoted arm 6 rotates, and oscillating deck 8 can be driven to rotate together with thread clamping mechanism; Move axially before and after pivoted arm 6, oscillating deck 8 front and back together with thread clamping mechanism can be driven to move axially; Meanwhile, oscillating deck 8 and thread clamping mechanism can rotate relative to pivoted arm 6, therefore are moved axially by the rotation of pivoted arm 6, the front and back of pivoted arm 6 and the rotation of oscillating deck 8 can realize thread clamping mechanism and rotates around peg or spindle 15.In the present embodiment, described pivoted arm 6 is provided with an oscillating motor 7, the output shaft of this oscillating motor 7 is fixedly connected with oscillating deck 8, thus driving oscillating deck 8 rotates, arm 6 rotates.
Certainly, also following structure can be adopted to do spatial movement to realize thread clamping mechanism around peg or spindle 15: described pivoted arm 6 is only rotatable, pivoted arm 6 is provided with one can before and after the oscillating motor 7 and that moves axially be positioned at oscillating deck 8 on rear side of pivoted arm 6, the output shaft of described oscillating motor 7 is fixed in oscillating deck 8, to drive oscillating deck 8 to rotate, described thread clamping mechanism is fixed on oscillating deck 8.Therefore, pivoted arm 6 rotates, and can drive oscillating motor 7, oscillating deck 8 rotates together with thread clamping mechanism; Oscillating motor 7 rotates, and oscillating deck 8 can be driven to rotate together with thread clamping mechanism; Move axially before and after oscillating motor 7, oscillating deck 8 front and back together with thread clamping mechanism can be driven to move axially; Therefore to be moved axially by the rotation of pivoted arm 6, the front and back of oscillating motor 7 and the rotation of oscillating motor 7 realizes thread clamping mechanism and rotates around peg or spindle 15.
In an initial condition, the peg or spindle 15 that the axle portion 301 of roll 3 is overlapped is the empty peg or spindle that a bottom line exhausts; When starting to carry out automatic winding to peg or spindle 15, rotated by pivoted arm 6, to move axially before and after pivoted arm 6 and oscillating deck 8 rotates three and be combined with each other and make the thread clamping mechanism be fixed on oscillating deck 8 do spatial movement, namely the thread clamping mechanism bottom line 29 that hold on line cylinder moves to the side of peg or spindle 15 and rotates N circle round peg or spindle 15, thus N circle on wrapping post bottom line 29 being wrapped in peg or spindle 15; Roll 3 rotates afterwards, and because the axle portion 301 on roll 3 and peg or spindle 15 are tight fit, therefore roll 3 drives peg or spindle 15 to rotate together, completes coiling work.Therefore, the peg or spindle automatic coiling device that the present invention relates to automatically can complete the coiling action of sky peg or spindle in Sewing machines, and its automaticity is very high, and without the need to manual operation, therefore time saving and energy saving, improve the operating efficiency of Sewing machines.
