Abstract
A sewing machine, wherein holding members (46) and (48) for holding a thread hung on a needle thread take-up (17) to be swung at a position on the downstream side of the needle thread take-up and on the upstream side of the sewing needle fitted to a needle bar are provided in a sewing machine head. During the rest of operation of the sewing machine head, the movement of the thread on the downstream side of the needle thread take-up is stopped irrespective of whether the needle thread take-up is swung or not since the thread (T) is held by the holding members. The tip of the thread hung on the needle thread take-up is passed through the pin hole of the sewing needle fitted to the needle bar. When the needle thread take-up is swung, the hung thread is tensed or loosened according to the swing movement. However, since the thread is held by the holding members on the downstream side of the needle thread take-up in the sewing machine head in the rest of operation, the thread passed through the pin hole is not extracted from the pin hole even if the needle thread take-up is swung. By such a simple structure, the thread can be prevented from being extracted from the pin hole.
Description
Technical field
Suture on the head of sewing machine in the present invention relates to work stopped keeps structure to make the Sewing machines of improvement, for example relates to having a plurality ofly rope band shapes such as band and cotton rope to be made member in the flush joint mode and stitching the multi-head sewing machine that is attached to the head of sewing machine on the cloth.Particularly relate to use multi-head sewing machine and when in a plurality of head of sewing machine some in work and the work of remaining head of sewing machine is in when stopping, can prevent the multi-head sewing machine that the pin hole of each suture needle on the head of sewing machine of suture from work is stopped is deviate from simple structure.
Background technology
In the past, the known multi-head sewing machine that a kind of following structure is arranged with a plurality of head of sewing machine, this head of sewing machine has: the bottom comprises the shank that the quilt of suture needle drives up and down; With described shank drive the thread take-up tension lever swing synchronously up and down; Be assembled in the same axle center of described shank on, the rotary body of the axle center rotation of cast-over bar freely; And rotate, guide rope band shape member into needle downing position (Japanese: pin unit position with this rotary body, be the pinprick position that suture needle is thrust on the cloth) guider, this sewing machine head can be on one side rotates the described rotary body of control accordingly with moving direction based on the cloth of the embroidery data of regulation, change the direction of guider so that the channeling direction at the pin place that falls of the suture needle of rope band shape member on described cloth keeps correct, in flush joint mode cloth on stitching attached this rope band shape member on one side.Have a plurality of multi-head sewing machines of head of sewing machine that can the attached rope band shape member of seam as this, known have a following various multi-head sewing machine: have the Sewing machines of a plurality of head of sewing machine that can only stitch attached rope band shape member and alternately have the head of sewing machine that can stitch attached rope band shape member and the Sewing machines of the sewing machine for embroidery head that can embroider usually etc.
But in the multi-head sewing machine of above-mentioned such type, following situation can appear in using method sometimes: only need allow part work, remaining head of sewing machine in a plurality of head of sewing machine not need work and be in the work dormant state.Connect shape ground and be provided with shared machine spindle in each head of sewing machine of multi-head sewing machine, the rotation by this machine spindle moves up and down the shank of each head of sewing machine, stitches attached rope band shape member thus on cloth.Therefore, as mentioned above, for the part work that makes head of sewing machine is stopped, must use known jumping out of (ジ ヤ Application プ) mechanism that the rotation of machine spindle is driven the transmission of shank is cut off, make shank be its rotation of no longer following machine spindle move up and down " jumping out of state ".Like this, in the head of sewing machine that work is stopped, the action of thread take-up tension lever is also stopped simultaneously.Particularly in the head of sewing machine that can stitch attached rope band shape member, in case work stop in the thread take-up tension lever swing, can cause that the suture of break-through in the pin hole of suture needle spurred by thread take-up tension lever and deviate from from pin hole.This is the cause because of the retaining member of the line end that does not dispose the maintenance suture of being located at the suture needle rear in the sewing machine for embroidery head in the head of sewing machine that can stitch attached rope band shape member.That is, have around the rotary body of the axle center rotation of shank, therefore the retaining member that keeps the line end of suture can not be arranged on the positions such as rear of suture needle, the line end of suture can not be kept owing to can stitch the head of sewing machine of attached rope band shape member.Thereby can cause the thread take-up tension lever pulling that break-through is swung in the suture of the pin hole of suture needle and deviate from from pin hole.
In order to solve above-mentioned bad phenomenon, record the Sewing machines that a kind of work at the head of sewing machine that can stitch attached rope band shape member can make the structure that the thread take-up tension lever swing of this head of sewing machine stops in stopping in the Japanese patent laid-open 8-299639 communique.The multi-head sewing machine that adopts this patent documentation to put down in writing, with the thread take-up tension lever axle of machine spindle configured in parallel on, the flange part of thread take-up tension lever is rotating and the state that slides along axis is supported on the Sewing machines horn around axis.At this moment, thread take-up tension lever is swung around the axis of thread take-up tension lever axle repeatedly by the thread take-up tension lever actuating arm, and thread take-up tension lever actuating arm and the rotation interlock that is fixed in the thread take-up cam of machine spindle.The axle of thread take-up tension lever axle is provided with spring, and applied force can make the mutual gear of the flange part of thread take-up tension lever and thread take-up tension lever actuating arm be in the position of engagement all the time, thereby power is passed to thread take-up tension lever from the thread take-up tension lever actuating arm.Supporting the pushing pin that thread take-up tension lever is slided on the Sewing machines horn slidably, when with manually will push pin and slide the time, pushing pin and thread take-up tension lever butt, thread take-up tension lever be slip together also.In a single day thread take-up tension lever slides, and the mutual gears engaged of the flange part of thread take-up tension lever and thread take-up tension lever actuating arm is thrown off, and will cut off to the transmission of power of thread take-up tension lever from the thread take-up tension lever actuating arm, and thread take-up tension lever becomes dormant state.At this moment, the relative thread take-up tension lever axle of thread take-up tension lever is keeping the swinging position of regulation, pushes the state after pin is retained slip simultaneously.Like this, when the work of head of sewing machine was stopped, by operation pushing pin, thread take-up tension lever also stopped, thereby the phenomenon that the suture of break-through in the pin hole of suture needle deviate from can not occur.
As mentioned above, in above-mentioned the sort of conventional art, in the work of the head of sewing machine that can stitch attached rope band shape member is stopped, do not deviate from order to make the suture of break-through in the pin hole of suture needle, the swing of thread take-up tension lever is also stopped.Therefore, for the swing that makes thread take-up tension lever is stopped, need to be provided with to support thread take-up tension lever slidably or to have and to make shut-off mechanism pushing pin that thread take-up tension lever slides etc., that will cut off to the transmission of power of thread take-up tension lever from machine spindle.Yet, in case this shut-off mechanism is set, not only make the complex structureization of head of sewing machine, and the assembling on Sewing machines is miscellaneous, exist cost to increase and time-consuming problem.
Again, in the multi-head sewing machine that above-mentioned patent documentation is put down in writing, for thread take-up tension lever is stopped with the operation that manually pushes pin, and when a plurality of head of sewing machine stop, must operate the pushing pin of each head of sewing machine of the object that stops respectively, not only bother, and consider and to forget this operation, preferably can operate automatically.But, for the pushing pin that makes each head of sewing machine can carry out automatically, the actuator that makes pushing pin slip usefulness must be set respectively on each head of sewing machine, there is the problem that this actuator can increase cost that is provided with.
Summary of the invention
In view of the above problems, the objective of the invention is to, provide the suture on the head of sewing machine during work stopped to keep structure to make the Sewing machines of improvement.Another purpose is, provides with simple structure in the work of the head of sewing machine that can stitch attached rope band shape member is stopped suture to be kept, even the driving of thread take-up tension lever is not stopped and can be prevented the multi-head sewing machine that the suture of break-through in the pin hole of suture needle deviate from yet thus.
Sewing machines of the present invention possesses head of sewing machine, this head of sewing machine has the shank that is driven up and down with the suture needle that is installed in the bottom, and with described shank drive the thread take-up tension lever swing synchronously up and down, it is characterized in that, in described head of sewing machine, be provided with retaining member, the suture that this retaining member is used for will passing in the position of the upstream of the suture needle of the downstream of this thread take-up tension lever and described shank described thread take-up tension lever is kept, when the work of described head of sewing machine is stopped, by using described retaining member that described suture is kept, make the suture action in the downstream that is positioned at this thread take-up tension lever to be stopped with described thread take-up tension lever action.Thus, need not make the simple structureization of head of sewing machine for the thread take-up tension lever action being stopped and special-purpose shearing device being set.Again, owing to retaining member is arranged on the position of upstream of the suture needle of the downstream of thread take-up tension lever and described shank, therefore, even exist rotary body also can not become obstruction around suture needle, the easy suture that can provide the quilt that is suitable for stitching attached rope band shape to make the head of sewing machine that member uses keeps structure.
Multi-head sewing machine of the present invention possesses a plurality of head of sewing machine, this head of sewing machine have the shank that drives up and down with the suture needle that is installed in the bottom, with described shank drive the thread take-up tension lever of swinging synchronously up and down; Be assembled into described shank on same axle center, can free cast-over bar the rotary body of axle center rotation; And rotate with this rotary body, rope band shape member is directed to the guider of the needle downing position of suture needle, with control described rotary body rotation accordingly based on the cloth moving direction of sewing style data, change the direction of guider on one side so that rope band shape member keeps correct to the channeling direction of the pin that falls of described suture needle, can on cloth, stitch attached this rope band shape member in the flush joint mode on one side, it is characterized in that, in described head of sewing machine, be provided with retaining member, the suture that this retaining member is used for passing described thread take-up tension lever is kept at the downstream position of this thread take-up tension lever, in the head of sewing machine of work that stops, by using described retaining member that suture is kept, the suture action in the downstream that is positioned at described thread take-up tension lever is stopped.
Thus, be provided for keeping the retaining member of suture in the downstream of the thread take-up tension lever of swinging, in the work of the head of sewing machine that can stitch attached rope band shape member is stopped, by using described retaining member that suture is kept, no matter whether described thread take-up tension lever swings the suture action that all can make the downstream that is positioned at this thread take-up tension lever stops.That is, in the work of head of sewing machine was stopped, the shank that drives up and down with the suture needle that is installed on the bottom drove no longer up and down, but thread take-up tension lever can be swung.Pass in the pin hole of the suture needle that the front end break-through of the suture of this thread take-up tension lever is installed with on shank.During the thread take-up tension lever swing, to wear the suture tension of hanging accordingly with swing or loosen, because in the head of sewing machine in work is stopped, use retaining member in the downstream of thread take-up tension lever, be that near the suture needle position keeps suture, therefore, no matter whether thread take-up tension lever moves, and the suture of break-through in pin hole can not deviate from from pin hole.Like this, adopt the present invention, the downstream that only needs to be arranged on thread take-up tension lever in described head of sewing machine is kept the retaining member of usefulness to get final product in suture, and in the work of head of sewing machine was stopped, even the action of thread take-up tension lever is not stopped, suture can not deviate from from pin hole yet.Like this, special-purpose shearing device need be set for the action that makes thread take-up tension lever is stopped, the simply constructed multi-head sewing machine of head of sewing machine can be provided, the cost that can suppress multi-head sewing machine increases.
As illustrated embodiments of the present invention, it is characterized in that, have pad body and interlinked mechanism, when described pad body is worked at described head of sewing machine, synchronously drive up and down with moving up and down of described shank, and when the work of described head of sewing machine was stopped, the retreating position of keeping out of the way the top drove no longer up and down, described interlinked mechanism keeps with the suture that will pass described thread take-up tension lever along with the action of keeping out of the way of described compress body makes described retaining member interlock.Like this, when the work of head of sewing machine is stopped,, therefore, need not set up actuator in addition in order to drive retaining member because the maintenance and the pad body of retaining member to suture carried out linkedly to the action of keeping out of the way of retreating position.Again, because the driving of retaining member is along with the action of keeping out of the way of pad body is carried out automatically, therefore, even the operator does not expressly carry out the driving operation of retaining member, suture also is in maintained state.
Like this, the present invention is applicable to the head of sewing machine that can stitch attached rope band shape member, will keep the retaining member of suture to be arranged to: in the work of head of sewing machine is stopped, to use described retaining member at the downstream position of thread take-up tension lever suture to be kept.Thus, even thread take-up tension lever action not stopping suture can not deviate from from pin hole yet,, have the simple structureization that makes head of sewing machine and can suppress the excellent results that cost increases so need disconnecting apparatus be set for thread take-up tension lever is stopped.
Again, owing to be that pad body when retaining member is stopped to the maintenance action of suture and head of sewing machine carries out linkedly to the action of keeping out of the way of retreating position, therefore, need not set up actuator in addition in order to drive retaining member, and incidental operator forgets the phenomenon of operation in the time of can preventing the operator with the manual operation retaining member.
