Unwinding yarn auxiliary device 1 possesses housing 18 as shown in Figure 5, and the control part 19 that is used for controlling above-mentioned unwinding auxiliary unit U is taken in and this housing 18.Housing 18 is fixed in the framework 21 of wind2 2.Control part 19 comprises drive circuit board, power supply of driving motor M etc.Housing 18 covers as shown in Figure 6 18a and is installed in the back side, control part 19 can be received into housing 18 by taking off this lid 18a.
And, in the side of housing 18 and the side of upper cover 40 rubber bush (bush) 38 is set respectively, will be connected with electrical motor M from the distribution 39 of control part 19 by these rubber bushs 38.Thus, control part 19 and electrical motor M are electrically connected.And, although not shown, also be connected with sensor 17 from the distribution 39 of control part 19.
Assist yarns Y from the unwinding of bobbin B by the unwinding yarn auxiliary device 1 that is consisted of by said structure.Follow yarns Y from the unwinding of bobbin B, the height of the chasing section 60 of bobbin B descends gradually.If sensor 17 detects the decline of this chasing section 60, then this detection signal is exported to control part 19.Then, the control part 19 that has received this detection signal drives the electrical motor M of the lifting mechanism 3 that is surrounded by above-mentioned encirclement mechanism 4, make slide mass 32 drop to assigned position, make movable cylinder 13 follow the height change of chasing section 60 and drop to new operating position.Movably the decline of the height change of following chasing section 60 of cylinder 13 is carried out repeatedly, until the yarns Y that is wound up on the bobbin B becomes about 1/3.
The height of unwinding auxiliary unit U integral body adapts with the up and down size of bobbin B and sets.Therefore, if the up and down change in size of the bobbin B that uses then needs the height of unwinding auxiliary unit U is carried out change and adjustment.Therefore, unwinding yarn auxiliary device 1 possesses to regulate unwinding auxiliary unit U as shown in Figure 5 with respect to the height regulating mechanism 5 of the height of bobbin B.
Height regulating mechanism 5 possesses the axle 50 as guide member, the hold assembly 51 that can control and remove axle 50 that guides along the vertical direction unwinding auxiliary unit U, the control lever of controlling and removing 52 that is used for operating hold assembly 51.The top and bottom of axle 50 are fixed to from the side of housing 18 along horizontally extending up and down a pair of protrusion 53.
The back of hold assembly 51 is installed in unwinding auxiliary unit U.Unwinding auxiliary unit U is in sagging state by axle 50 and hold assembly 51 supportings above bobbin B.Hold assembly 51 can move along axle 50 when not controlling axle 50.Because unwinding auxiliary unit U and hold assembly 51 mobile with becoming one, so unwinding auxiliary unit U is guided along axle 50 towards above-below direction.
In addition, the loading and unloading parts (not shown) that unwinding auxiliary unit U and hold assembly 51 usefulness bolts etc. can load and unload are installed.Therefore, the operator only just can once take off sagging unwinding auxiliary unit U integral body by taking off these loading and unloading parts, and the maintenance of unwinding auxiliary unit U is easy.
The control lever 52 that is installed on the hold assembly 51 constitutes: make hold assembly 51 control axle 50 by rotating along a direction, by removing controlling of 51 pairs of axles 50 of hold assembly along counter-rotation.If the operation by control lever 52 makes hold assembly 51 control axle 50, then gripping power is had an effect, and hold assembly 51 is fixed in axle 50, so unwinding auxiliary unit U is positioned fixing.
When the change of the up and down size of following bobbin B, when adjusting unwinding auxiliary unit U with respect to the height of bobbin B, the operator is operating operation bar 52 at first, removes controlling of 51 pairs of axles 50 of hold assembly.Then, make unwinding auxiliary unit U move to the height of the hope that the up and down size with bobbin B matches along axle 50.Then, operating operation bar 52 makes hold assembly 51 control axle 50 again, unwinding auxiliary unit U location is fixed on the height of hope.
Like this, the operator only carries out the operation of controlling and removing of hold assembly 51 by the control lever 52 that is positioned at unwinding yarn auxiliary device 1 front, just can adjust unwinding auxiliary unit U with respect to the height of bobbin B.That is, not serviceable tool, by manual working, easily carry out unwinding auxiliary unit U with respect to the height adjustment of bobbin B.
In addition, on axle 50, also can be provided for the mark (not shown) of unwinding auxiliary unit U location.Be labeled as and for example on axle 50, separate along the vertical direction the additional scale of predetermined distance.Scale only otherwise controlling of axle 50 brought impact for hold assembly 51 can be additional by directly being engraved on the axle 50.By such mark is arranged on the axle 50, the operator can more easily carry out the height adjustment of unwinding auxiliary unit U.
The present embodiment is owing to consisting of the guide member that guides along the vertical direction hold assembly 51 with axle 50, and therefore only by said structure, hold assembly 51 is around axle 50 rotations.If hold assembly 51 is around axle 50 rotations, then unwinding auxiliary unit U rotates centered by axle 50.When carrying out the height adjustment of unwinding auxiliary unit U, even unwinding auxiliary unit U is positioned on the height of hope, if unwinding auxiliary unit U is a little rotation centered by axle 50, the central axis of stationary magazine creel 11 and movable cylinder 13 is also from the center axis deviation of bobbin B.
Therefore height regulating mechanism 5 possesses to limit the rotation restricting unit 54 of the rotation of unwinding auxiliary unit U centered by axle 50.Rotation restricting unit 54 extends setting abreast with axle 50, is fixed in the side of housing 18.And as shown in Figure 5 and Figure 6, rotation restricting unit 54 engages with the recess 55 that forms along the vertical direction on hold assembly 51, and hold assembly 51 is rotated limiting part 54 guiding and along the vertical direction slippage.
And because by this engaging, hold assembly 51 becomes can not be around axle 50 rotations, the rotation of as a result unwinding auxiliary unit U centered by axle 50 is limited.The central axis that thus, can the keep bobbin B state consistent with the central axis of stationary magazine creel 11 and movable cylinder 13, make unwinding auxiliary unit U move to height and the location of hope.
And, rotation restricting unit 54 as shown in Figure 5 its up and down size form shortly than the up and down size of axle 50, be fixed on the side of housing 18, to be located in the altitude range with respect to the regulation of axle 50.Therefore, if make hold assembly 51 along axle 50 upward or the below move and leave the altitude range of rotation restricting unit 54, then the releasing that engages of depressed part 55 and rotation restricting unit 54 can be taken off hold assembly 51 from rotation restricting unit 54.That is, the operator can remove the restriction of the rotation centered by axle 50 of unwinding auxiliary unit U.
If the operator removes the rotation of unwinding auxiliary unit U and limits, unwinding auxiliary unit U is rotated, then owing to the encirclement mechanism 4 that is positioned at housing 18 rears moves, therefore guarantee working space at the rear of housing 18 centered by axle 50.Thus, the operator can take off the lid 18a at housing 18 back sides, can carry out maintenance and the taking-up of the control part 19 in the housing 18.That is, rotation required when utilizing the said structure operator can remove wittingly the height adjustment that carries out unwinding auxiliary unit U limits, and can guarantee for the working space of safeguarding.
Unwinding yarn auxiliary device 1 of the present utility model is not limited to above-described embodiment.The Cylinder feeder mechanism 3 of automatic bobbin winder is the pellet type feedway in above-described embodiment, but also can adopt bobbin magazine formula feedway.And, although be provided with to locate the scale of unwinding auxiliary unit U at axle 50, in the time of also can being arranged on the operators such as the front of rotation restricting unit 54, housing 18 or side and adjusting height on the visual easy position.
For dustproof extensible member as covering lifting mechanism 3 has adopted bellows parts 41, but be not limited to this.Extensible member also can be other structure so long as can protect lifting mechanism 3 to make the dust isolation such as itself and willow catkins flying in the air, can follow the flexible along the vertical direction parts of lifting of movable cylinder.For example, extensible member also can be nested successively by the size of diameter by the cylindrical shell that a plurality of diameters are different, thus the continuous cylindrical shell that can consist of along the vertical direction with extending.
In Fig. 4, represent to possess the encirclement mechanism 4 that bellows parts 41 and cup part 42 are arranged, but be not limited to this.Structure shown in Figure 7 is for example arranged.Make among Fig. 7 that the upside of connecting member 43 is the same with Fig. 4 to be consisted of with the 1st bellows parts 41a, the 2nd bellows parts 41b rather than cup part 42 that the downside of connecting member 43 is remained silent with the lower end consist of.The upper end of the 2nd bellows parts 41b is installed on the connecting member 43.Be fixed wtih the lower support parts 34 of screwed part 30 and supporting guide member 31 in the lower end of the 2nd bellows parts 41b.Other structure is identical with Fig. 4.
According to this structure, the movable cylinder of lifting is 13 o'clock using electrical motor M lifting slide mass 32, the upper end lifting of the 2nd bellows parts 41b, but lower end not lifting because being fixed in lower support parts 34 of the 2nd bellows parts 41b.Therefore, follow the lifting of movable cylinder 13, the 1st bellows parts 41a not only, the 2nd bellows parts 41b is also flexible along the vertical direction.If movable cylinder 13 descends, then the 1st bellows parts 41a elongation, the 2nd bellows parts 41b shortens (Fig. 7 A).If movable cylinder 13 rises, then the 1st bellows parts 41a shortens, and the 2nd bellows parts 41b extends (Fig. 7 B).Can not enter inner such gap at encirclement mechanism 4 formation willow catkins flying in the air even the movable cylinder 13 of this structure rises yet, keep protection against dust.
As can understanding from Fig. 7 A, B, according to this structure, even 13 liftings of movable cylinder, the position of the lower end of the 2nd bellows parts 41b is also constant, therefore surrounds mechanism 4 and does not change from the height H of basal surface 62.Therefore, different from the embodiment of Fig. 4, make lifting mechanism 3 sagging in, not should be noted that from the height H of basal surface 62.But, different from the embodiment of Fig. 4, because consisting of the 2nd bellows parts 41b of the bottom that surrounds mechanism 4 is the parts with retractility, therefore the situation of splitting because of the yarns Y contact is arranged, owing to existing willow catkins flying in the air etc. to enter the worry of damaging protection against dust from the part of splitting, so this point has necessity of being careful.
