Background technology
The selvage machine of using as shuttleless loom, known have by utilizing planetary gears that two limit yarn feedwaies are revolved round the sun while rotation carry out the planet selvage machine (planetary gear type selvage machine) that so-called planetary motion is reversed two limit yarns.
What Fig. 3 represented is an example of this type of planet selvage machine.In illustrated planet selvage machine, an opposite side yarn feedway 50,50 is supported on the support gear 80 as support disk, on this support gear 80, is engaged with driven wheel 70.The driving shaft 71 that driven wheel 70 is rotarilyd actuate by the driving mechanism with not shown drives, and often revolves the ratio turning around that turns around support gear 80 is rotated with the main shaft 2 of loom.Limit yarn feedway 50 is supported by rotating shaft 55, and is arranged to can relatively rotate with support gear 80, and rotating shaft 55 is supported on support gear 80 freely by bearing rotary.
Rotating shaft 55 is supporting limit yarn feedway 50 and is connecting support gear 80 in its one end, at its other end, planetary gear 53 can not be installed with the relative rotation.Planetary gear 53 engages with the idler gear 93 that rotation is supported on support gear 80 freely, and this idler gear 93 engages with central gear 91.Central gear 91 is not supported on the frame F of loom revolvably, in detail, is not supported on revolvably on Support bracket 100, and this Support bracket 100 is arranged on the beam B between the frame F that is set up in pairing left and right loom.
According to these structures, in planet selvage machine, each limit yarn feedway 50 is accompanied by the rotation of support gear 80 and revolves round the sun around the rotation 80a of support gear 80.In addition, because the planetary gear 53 being arranged on rotating shaft 55 engages with fixing central gear 91 by idler gear 93, thereby each limit yarn feedway 50 is accompanied by above-mentioned revolution rotation centered by the rotation 55a of rotating shaft 55.,, for planet selvage machine, the rotation that each limit yarn feedway 50 is accompanied by support gear 80 is revolved round the sun while the planetary motion of rotation.
Each limit yarn feedway 50 has the limit yarn bobbin 52 of the limit yarn of having reeled, and the limit yarn of drawing from each limit yarn bobbin 52 is connected with the selvedge of fabric weaving.Thereby the opposite side yarn that planet selvage machine makes to draw from each limit yarn bobbin 52 by the above-mentioned planetary motion of each limit yarn feedway 50 carries out harness motion while both are reversed mutually, form and reverse limit at the selvedge of fabric.
In addition, illustrated planet selvage machine has the gear cover 101 being arranged on Support bracket 100, and the gear train being made up of support gear 80, planetary gear 53, idler gear 93 and central gear 91 is accommodated in gear cover 101.But, in Fig. 3, for the internal structure that represents this gear train etc. represents gear cover 101 with section.In addition, in the figure, make for the support knot that represents planetary gear 53 and idler gear 93, support gear 80 changes phase place with the first half and the latter half and represents.Therefore, the limit yarn feedway 50 use imaginary lines (double dot dash line) of downside represent.
An example of the limit yarn feedway using as this type of planet selvage machine, has No. 5-321082 disclosed device of Unexamined Patent of Japanese publication publication communique.Fig. 4 represents the device identical with the disclosed limit of the prior art communique yarn feedway.
As shown in Figure 4, the limit yarn feedway 50 that known planet selvage machine is used has the spool stand 51 take the main body of section U font as main body, the main body of this section U font is made up of diapire 51a and mutual pair of sidewalls 51b, the 51b that relatively erects the both ends that are arranged on diapire 51a, and by the shaft of bobbin 51c that connects each sidewall 51b and be erected between two side 51b, 51b, limit yarn bobbin 52 is supported between two side 51b, 51b.
In addition, conventionally, on limit yarn bobbin 52, be formed with the axis hole 52c that inserts shaft of bobbin 51c, embed and be not provided with revolvably the bobbin cover 52b with bead as shown in the figure at each end at the two ends of this shaft of bobbin 51c.In addition, on each bobbin cover 52b, be formed with the through hole that inserts shaft of bobbin 51c.Therefore, the internal diameter of axis hole 52c is larger than the diameter of axle of shaft of bobbin 51c, under the state in the through hole that shaft of bobbin 51c is inserted into two bobbins covers 52b, 52b, between the inner peripheral surface of axis hole 52c and shaft of bobbin 51c, has gap.And limit yarn bobbin 52 becomes and overlaps 52b by bobbin and be supported on the state on shaft of bobbin 51c.
In addition, spool stand 51 has: for guiding the limit yarn guiding piece 51e of the limit yarn of drawing from limit yarn bobbin 52; And be arranged on Sha Cong limit, limit yarn bobbin 52 to the tension adjustment mechanism 51d in the path of the thread guide eyelet of limit yarn guiding piece 51e.In addition, though illustrated tension adjustment mechanism 51d can change with ratchet mechanism the mated condition of ratchet and ratchet according to the tension force of limit yarn, because itself being that the description thereof will be omitted in this manual for known structure.
In the limit of this structure yarn feedway 50, when the center of gravity of spool stand 51 itself is observed in the direction of the axis 55a of rotating shaft 55 (while observation as the direction of Fig. 4 (a)), in the direction orthogonal with shaft of bobbin 51c and the direction parallel with the diapire 51a (direction of illustrated two arrow X/following, be called " directions X ") on, with respect to the position (=axle center) of the axis 55a of rotating shaft 55,, the rotation center of limit yarn feedway 50 is (following, referred to as " rotation " center ") position, in the position of leaving to limit yarn guiding piece 51e.This is because limit yarn guiding piece 51e is arranged on the position of departing from rotation center 50x, and the tension adjustment mechanism 51d being made up of multiple parts is also arranged on limit yarn guiding piece 51e side.
Explanation in passing, if the center of gravity (overall center of gravity) of limit yarn feedway 50 entirety is in leaving the state of rotation center 50x, be the non-equilibrium state of overall center of gravity in relative rotation center 50x bias,, at limit yarn feedway 50 time rotationals, opposite side yarn feedway 50 acts on the eccentric load being caused by centrifugal force.Its result, limit yarn feedway 50 and the rotating shaft 55 rotating with limit yarn feedway 50 one, planetary gear 53 (following, to be called " system of limit yarn feedway ") produce vibration.
But, all the time, while running, produce the problem of system failure of the limit yarn feedway of planet selvage machine and so in the time that loom carries out long time continuous working and with high speed.And in the past, its reason is considered to owing to acting on due to the eccentric load of above-mentioned limit yarn feedway.So general limit yarn feedway so far, in order to eliminate non-equilibrium state as above, is designed so that overall center of gravity is as far as possible near rotation center.
In more detail, in existing general limit yarn feedway, at least with regard to the position at the rotation center of relatively above-mentioned directions X, with dispose shaft of bobbin and the limit yarn bobbin as the opposing party's weight as the limit yarn guiding piece of a side weight and the contrary side configuration of tension adjustment mechanism one side, and to obtain with the balance of yarn guiding piece and tension adjustment mechanism weight the position that makes overall center of gravity approach the limit yarn bobbin at rotation center, and set the installation site of the shaft of bobbin of spool stand in the mode that limit yarn bobbin is configured in this position.But the weight of limit yarn bobbin is because the coiling amount according to limit yarn changes, thereby be accompanied by the consumption of limit yarn in weaving process, the position of the overall center of gravity (following, referred to as " overall center of gravity ") of limit yarn feedway also changes.Therefore, in the yarn feedway of existing limit, clip the position at rotation center and the mode that changes (for example,, when the coiling amount of limit yarn reaches half degree, making the overall center of gravity of directions X and the position consistency at rotation center) configures limit yarn bobbin with the position of its overall center of gravity.
But even in the existing limit yarn feedway forming like this, the system that still can produce limit yarn feedway produces the problem that the bearing of vibration, supporting rotating shaft and planetary gear damage and so on.So, what inventor of the present invention studied repeatedly with keen determination found that, the vibration producing about the system of limit yarn feedway especially causes the reason of the vibration of above-mentioned parts damages degree to understand: compared with acting on the impact of eccentric load of above-mentioned limit yarn feedway, not equal to the impact being brought by other reason is larger.Details is as follows.
In overall center of gravity as prior art, near the occasion at rotation center, it is large that the distance at the rotation center apart from rotation (axis of=shaft of bobbin) of the limit yarn bobbin of directions X becomes.And, in existing general limit yarn feedway, as shown in Figure 4, if with limit yarn bobbin 52 position relationship with rotation center 50x, make the structure outside the 52a of cylinder portion that rotation center 50x is positioned at limit yarn bobbin 52.In addition, in above-mentioned prior art communique, in illustrated structure, rotation center 50x is also positioned at the outside of the cylinder portion of limit yarn bobbin.
In addition, the center of gravity of limit yarn bobbin 52 self is positioned on its rotation, is positioned on the axis of shaft of bobbin 51c.Therefore, with regard to the structure of above-mentioned prior art, rotation center 50x is positioned at the illustrated structure in the 52a of the cylinder portion outside of limit yarn bobbin 52, and it is large that the distance of the center of gravity of rotation center 50x and limit yarn bobbin 52 becomes.
But, in the yarn feedway of limit, in the time that limit yarn bobbin is installed on spool stand, first, under the state that shaft of bobbin is pulled down from spool stand, between the two side of spool stand, insert limit yarn bobbin.Secondly, make to be formed at the position consistency of hole that the insertion shaft of bobbin on each sidewall of spool stand uses and the through hole of the bobbin cover of limit yarn bobbin, from a side insertion shaft of bobbin of a sidewall.Then, connect at shaft of bobbin under the state of two side of limit yarn bobbin and spool stand, carry out by push part, the head of shaft of bobbin being pressed into and become the operation of anti drop-off state etc.
Carrying out in the installation exercise of this limit yarn bobbin, in order to carry out smoothly and easily limit yarn bobbin to the insertion between the two side of spool stand, in general limit yarn feedway, it is slightly large that the interval of the part of the insertion limit yarn bobbin of the two side of spool stand is formed as width than limit yarn bobbin (distance between the outside end face of two bobbins covers).Therefore, be arranged at limit yarn bobbin under the state of spool stand, between the sidewall of spool stand and the outside end face of limit yarn bobbin (bobbin cover), have small gap.
Like this, between the sidewall of spool stand and the outside end face of limit yarn bobbin, exist in the structure in gap, in the case of the relative rotation of the center of gravity center bias of limit yarn bobbin, be accompanied by the planetary motion of limit yarn feedway, yarn bobbin axis direction at shaft of bobbin between the two side of spool stand in limit vibrates.In detail, in the time that limit yarn feedway carries out planetary motion, limit yarn bobbin is owing to being accompanied by the centrifugal force of revolution and being subject to the power of axis direction.And, revolve round the sun also due to limit yarn feedway while carry out rotation, thereby the direction of the power of opposite side yarn bobbin effect constantly changes in a circle of revolution, at axis direction, revolving the middle direction reversion and then return of turning around.Therefore, limit yarn bobbin comes and goes displacement with the distance that is equivalent to above-mentioned gap along axis direction due to the existence in above-mentioned gap in a circle of revolution, is accompanied by the planetary motion of limit yarn feedway and vibrates between two side.
And the power of opposite side yarn bobbin effect is proportional with the distance of the center of gravity from rotation center to limit yarn bobbin.Therefore, prior art described above is such, and in the case of the distance of the center of gravity from rotation center to limit yarn bobbin is large, the power that acts on limit yarn bobbin becomes large, and in the time of above-mentioned vibration, limit yarn bobbin produces violent collision to the two side of spool stand.Its result, limit yarn feedway vibrates because of this collision load, and the whole system of limit yarn feedway is also vibrated thereupon, and it becomes former thereby causes bearing and the planetary damage of supporting rotating shaft.In addition, in the structure of this existing limit yarn feedway, because the violent collision of limit yarn bobbin and spool stand also causes the damage of limit yarn feedway itself.
Like this, all the time, because the vibrative reason of system at limit yarn feedway has only considered to act on respect to the bias at rotation center due to overall center of gravity the impact bringing of the eccentric load of limit yarn feedway, do not consider the impact that the vibration of the axis direction by limit yarn bobbin as above brings completely, thereby still cannot avoid the damage of device.
Summary of the invention
Therefore, task of the present invention relates to the limit yarn feedway of using for the planet selvage machine of loom, alleviate the vibration of the system of the limit yarn feedway that the vibration of the axis direction of the limit yarn bobbin that the planetary motion because being accompanied by limit yarn feedway produces causes, prevent limit yarn feedway and the damage of the parts that have.
