The right side of Fig. 1 of arm 5 on operation post 2 is upright is establishing plug wire stand 15, near the portion upper end of this plug wire stand 15, promptly is provided with spool mounting table 16 than arm 5 high positions.Upload in this spool mounting table 16 and to be equipped with spool 17.The user pulls out line 18 from the spool 17 of the required suture color that is used for making, the feed path of reaching the standard grade by regulation with the line break-through in suture needle 10.On the other hand, line 18 is pulled out from spool 17, by the feed path that rolls off the production line described later, can be by the Winder 28 that rolls off the production line with in the shuttle 13 that rolls off the production line of line 18 coilings in the shuttle that is installed on line seizure usefulness.
As shown in Figure 5, in arm 5, machine spindle sets along left and right directions, rotatably is bearing on the Sewing machines framework 7 by pivot by bearing 12.Fixing manually belt pulley 20 in the right part of machine spindle 8.On this manual belt pulley 20, be formed with belt grooves 20a,, be formed with the cylindric operating portion 20b that stretches out to the axial right side of machine spindle 8 simultaneously at its peripheral part.The user is with this cylindric operating portion 20b of manual rotatable operation.That is, manual belt pulley 20 is exposed to the outside from the right part of the Sewing machines framework 7 of arm 5.
Downside at machine spindle 8 is provided with not shown electrical motor of sewing machine, the horizontal vee-belt 21 of hanging among the belt grooves 20a of drive pulley on being fixed on the driving shaft of electrical motor of sewing machine and manual belt pulley 20.This machine spindle 8 and manual belt pulley 20, by electrical motor of sewing machine by vee-belt 21 towards the direction of rotation integrated of regulation be rotated driving.
The right side of arm 5 and column sections 4 (right side of Fig. 1) end face was covered by the belt lid 22 (being equivalent to the side cover).As Fig. 1, Fig. 4, shown in Figure 5, the width of roughly the latter half of this belt lid 22 is bigger, is formed up to the outer end of the cylindric operating portion 20b of manual belt pulley 20 always.
The following describes belt wheel cap 25.Belt wheel cap 25 is that synthetic resin is made, and as Fig. 1～shown in Figure 6, except the Outboard Sections 20Ea (as shown in Figure 3 and Figure 4) of manual belt pulley 20 bottoms, also forward part 20Eb and the rear section 20Ec with manual belt pulley 20 covers.In this occasion, on belt wheel cap 25, cover described Outboard Sections 20Ea lower end cap 25a, cover manual belt pulley 20 forward part 20Eb preceding cap 25b and to cover the continuous shape of the back cap 25c ground of rear section 20Ec integrally formed.
This belt wheel cap 25 is structures that turn back cap 26 and skewed cap 27 is integrally formed, and it is 22 integrally formed that this belt wheel cap 25 and described belt cover.
About 140 degree ground of the cap 26 of turning back the and locally end portion of the cylindric operating portion 20b of manual belt pulley 20 being covered are the structures of turning back along all sides in interior all side direction of its end portion in a kind of bending ground.
Skewed cap 27 be on belt wheel cap 25 with the outer circumferential side of the manual cylindric operating portion 20b of belt pulley 20 accordingly to the structure of arm 5 lopsidedness, be a kind of forms that belt wheel cap 25 and belt lid 22 are linked.
Below, the Winder 28 that rolls off the production line that is arranged at above the arm 5 is described with the way that is arranged at the line feed path from spool 17 to the Winder 28 that the rolls off the production line tension regulator 29 that the rolls off the production line middle part, towards the top.
As shown in Figure 2, the Winder 28 that rolls off the production line has: the bolster 30 of the vertical direction of the rotatably mounted shuttle 13 that rolls off the production line; Wire winding pole 31 rotatable around the vertical axle center, that the line 18 that is wrapped in the shuttle 13 that rolls off the production line is pushed from sidepiece etc.Because of identical with the structure of the common Winder that rolls off the production line, its detailed description of Therefore, omited.
The structure of tension regulator 29 that rolls off the production line is identical with tension disk 6 in being located at the feed path of reaching the standard grade, and line 18 between the 1 pair of clamp 32,33 that applies elastic force, that supplied with from spool 17 provides tension force.And, on this rolls off the production line tension regulator 29, be provided with the 1st wire element 34 to line 18 channeling conducts of being supplied with from spool 17; And will be via the 2nd wire element 35 of 18 downward wire-wound line apparatus 28 guiding of the line between 1 pair of clamp 32,33.At this, the coiling path of rolling off the production line of so-called regulation, exactly from spool 17 via the line feed path of tension regulator 29 that roll off the production line to the Winder 28 that rolls off the production line.
Be involved in occasion in the shuttle 13 that rolls off the production line at the line 18 with spool 17, the shuttle 13 that at first will roll off the production line is installed on the bolster 30, and the line 18 that will pull out from spool 17 is according to via the 1st wire element 34; Between 1 pair of clamp 32,33; This is involved in the 2nd wire element 35 in the shuttle 13 that rolls off the production line in proper order.Then, wire winding pole 31 rotating operations to the side that winds the line, by driving electrical motor of sewing machine, can be automatically be involved in the line 18 of spool 17 in the shuttle 13 that rolls off the production line.
The following describes the effect and the effect of the belt wheel cap 25 of this structure.
Be involved in the winding operation that rolls off the production line in the shuttle 13 that rolls off the production line in the coiling path of rolling off the production line when beginning by aforesaid regulation, through regular meeting take place the user with line 18 from the too much phenomenon of the amount of pulling out of spool 17.
In this occasion, the roughly lax LSOR part 18a that excessively causes of U word shape can take place in downside.Under this state, when rolling off the production line winding operation, as shown in Figure 6, the LSOR part 18a that relaxes into this U word shape contacts with the cylindric operating portion 20b of the manual belt pulley 20 that rotates driving, and the downside of isochrone slack 18a is along interior all side shiftings of the end portion of cylindric operating portion 20b.
Even this occasion, also cap 26 covers because this interior all side is turned back, so can prevent reliably that principal vertical line 18 is involved in the manual belt pulley 20.
On the other hand, line 18 is taking place from the too much occasion of the amount of pulling out of spool 17, in the thread path part of the 1st wire element 34 from spool 17 to the tension regulator 29 that rolls off the production line, the roughly lax LSOR part 18a that excessively causes of U word shape can take place in downside.In this occasion, as Fig. 1～shown in Figure 4, the slackness of line 18 is bigger, arrives the belt lid 22 of the downside of manual belt pulley 20 right flanks always.
Under this state, corresponding with the state that line 18 is wound in the shuttle 13 that rolls off the production line when driving electrical motor of sewing machine and roll off the production line winding operation, at first, relax into this roughly the slack of the line part 18a of U word shape reduce gradually.At this moment, LSOR part 18a is side shifting upwards gradually, at first as shown in Figure 5, though tangled by the end portion of manual belt pulley 20 easily during package, but owing to this end portion is covered by lower end cap 25a and skewed cap 27, therefore, under skewed cap 27 and lower end cap 25a guiding, can easily cross manual belt pulley 20, can after manually belt pulley 20 tangles, not rise.
At this moment, among Fig. 4, LSOR part 18a, though at the forward part 20Eb of the manual cylindric operating portion 20b of belt pulley 20 with manually also roughly tangled easily simultaneously on the rear section 20Ec of the cylindric operating portion 20b of belt pulley 20, but these parts 20Eb, 20Ec are covered by preceding cap 25b and back cap 25c respectively, so can avoid being involved in.Can prevent from reliably to be involved in the manual belt pulley 20 thus.
On manual belt pulley 20, if the bottom and the front and rear part thereof that easily tangle also can be avoided, then after it, the phenomenon of LSOR part 18a with regard to not taking place at all to be tangled by manual belt pulley 20 can successfully be eliminated all LSOR part 18a.Its result directly supplies with the 1st wire element 34 from the line 18 of spool 17, carries out winding operation according to the regular coiling path of rolling off the production line.
Like this, has spool 17, Winder 28 rolls off the production line, tension regulator 29 and manually in the Sewing machines of belt pulley 20 rolls off the production line, the belt wheel cap 25 that covers because of the Outboard Sections 20Ea that has the bottom at least of manual belt pulley 20, so line 18 is taking place from the too much occasion of the amount of pulling out of spool 17, online 18 roughly U word shape ground arrive under the lax excessive like that state of the downside in manual belt pulley 20 outsides, even driving electrical motor of sewing machine, carry out the winding operation of rolling off the production line by the Winder 28 that rolls off the production line, also can utilize belt wheel cap 25 to prevent that the LSOR part 18a of U word shape roughly from entering the end portion of manual belt pulley 20.And this belt wheel cap 25 simple in structure only need be provided with simple belt wheel cap 25, can prevent reliably that LSOR part 18a is wound onto on the machine spindle 8 of manual belt pulley 20, and can reduce the cost of Sewing machines 1.
Except the cap 25a of lower end,,, thus, can prevent from reliably to be involved in the manual belt pulley 20 so can further avoid reliably being involved in because of belt wheel cap 25 also comprises preceding cap 25b and back cap 25c again.
Again, because belt wheel cap 25 is with lower end cap 25a, preceding cap 25b, the continuous structure of back cap 25c, so can successfully prevent being involved in of principal vertical line 18.
Again, owing on belt wheel cap 25, be formed with the cap 26 of turning back of turning back along the inside all sides of the shape of manual belt pulley 20, therefore, even the structure that interior all sides of manual belt pulley 20 are turned back can prevent reliably that also principal vertical line 18 is involved in the manual belt pulley 20.
And, because on belt wheel cap 25, manually the outer circumferential side of belt pulley 20 is formed with to the oblique skewed cap 27 of arm 5 inclinations, therefore, also can successfully be crossed manual belt pulley 20 around the line 18 of going into manual belt pulley 20 downsides, can prevent from reliably to be involved in.
Be on the belt lid 22, owing to belt wheel cap 25 being arranged on the side cover so be convenient to the part management of lid again.
In this occasion, because that belt wheel cap 25 and this belt cover is 22 integrally formed, therefore, not only belt can be covered 22 and be shaped simultaneously, and belt lid 22 and belt wheel cap 25 can be installed simultaneously with belt wheel cap 25, can improve making property and assembleability, and can reduce cost.
