[patent documentation 2] Japan Patent spy opens communique 2005-No. 80895
But the sewed fabric moving device of patent documentation 1 and patent documentation 2 all is that sewn object is centered on a plurality of rollers and the structure of drawout maintenance.But in this structure, when sewn object was between adjacent roller, its surface was plane substantially (linearity, curvature are zero), and when being centered around on each roller, its surface becomes macrobending state (deep camber) along roller.Thus, its surperficial flexibility of handover of sewn object fore-and-aft direction when making changes greatly.Therefore,, still exist sewing position and lax possibility takes place periphery, can not prevent the style dislocation of making reliably even the limit, cloth cross direction two ends that resembles the patent documentation 2 sewn object keeps.
Summary of the invention
In view of the above problems, the object of the invention is, provides can prevent effectively along with making the sewed fabric moving device that the sewn object generation of carrying out sewing position relaxes and can prevent to make the Sewing machines of style dislocation.
In order to solve above-mentioned problem, the sewed fabric moving device of Sewing machines of the present invention, it is characterized in that possessing: with the mutual barrier-like of sewn object transverse width corresponding intervals a pair of rotary body that is configured, moves along the track of circle shape or arc-shaped bend separately; The driving mechanism that is used to make described a pair of rotary body to move synchronously along the track of described bending; And be used for respectively a pair of retaining member that each end of described sewn object transverse width direction kept along described rotary body, use described retaining member, described sewn object is kept to sprawl the curved state of embayment along the track of the described bending of described rotary body, the described sewn object that is kept by this retaining member along with moving of described rotary body along described orbital motion.
Adopt this structure, owing to respectively each end of sewn object transverse width direction is kept along a pair of rotary body, therefore, this sewn object can be kept to sprawl the curved state of embayment along the track of the round shape of this rotary body or arc-shaped bend, this maintained sewn object along with the rotation of this rotary body along the track handover of this circle shape or arc-shaped bend.The result of this sewed fabric moving along this warp rail is a sewn object to vertical sending to of (Y direction).Like this, its surface of sewn object is being kept stable case of bending and can be carried out vertically (Y direction) swimmingly and transfer.Adopt the present invention, when sewn object along with the carrying out of making when the Y direction moves, because of the case of bending on sewn object surface does not change, take place laxly so can prevent to be sprawled the sewn object that remains on the sewing position effectively, can prevent to make finished product reliably and produce the style dislocation.
As an example, also can between described a pair of rotary body, supporting member be set, described supporting member will be along this rotary body and be sprawled and be held in crooked planar described sewn object and supported along this flexure plane.Adopt this structure and since the body that relatively moves be held member be held in crooked planar sewn object can also be supported from the below along this flexure plane, therefore, can utilize rotary body to carry out the handover of sewn object more swimmingly.Again, crooked planar because of between a pair of rotary body, sewn object being supported to, so even between a pair of rotary body the occasion of stretching sewn object, can prevent more effectively that also the sewn object of sewing position from taking place to relax.Like this, as if the shuttle seat periphery that described supporting member is arranged at least Sewing machines, can prevent more reliably that then the sewn object of sewing position from taking place lax.
Again, sewed fabric moving device of the present invention possesses slide mechanism again on the basis of said structure, described slide mechanism makes described a pair of rotary body and head of sewing machine and the shuttle seat corresponding with it do relatively to slide on the transverse width direction of described sewn object.This sewn object is to make the sewn object that remains on the rotary body and head of sewing machine make relatively laterally (directions X) to send to towards the result who relatively slides of transverse width direction.Like this, just can make sewn object and head of sewing machine do relatively laterally to reach vertical (directions X and Y direction) according to the requirement of sewing pattern sends to.
As an example, described slide mechanism is characterised in that to possess: described a pair of rotary body rotation is bearing in freely the supporting member that slides on described sewn object transverse width direction along on the direction of the track of described round shape or arc-shaped bend and with a pair of rotary body of this supporting; And the slip drive division that described supporting member is slided on described sewn object transverse width direction, the described sewn object that is kept by described retaining member moves on its transverse width direction along with the slip of described supporting member with described rotary body.In this occasion, because of head of sewing machine and shuttle seat do not move, a pair of rotary body moves on the transverse width direction of sewn object, so slide mechanism is oversimplified.
As another example, described slide mechanism is characterised in that to possess: with described head of sewing machine and connect into relative sewing machine frame with its corresponding shuttle seat and the connecting portion that carries out the one slip on the transverse width direction of described sewn object; And the slip drive division that described connecting portion is slided on the transverse width direction of described sewn object, described head of sewing machine and the shuttle seat corresponding with it move on the transverse width direction of described sewn object along with the slip of described connecting portion.In this occasion, because of a pair of rotary body does not move on the transverse width direction of sewn object, head of sewing machine and shuttle seat move on the transverse width direction of sewn object, so the mechanism of rotary body is oversimplified.
Adopt the sewed fabric moving device of Sewing machines of the present invention, can prevent sewn object effectively, can prevent the style dislocation of making along with relaxing of making.

[the 1st embodiment]
Fig. 1 is the front view of the multi-head embroidery sewing machine (being designated hereinafter simply as " Sewing machines ") that possesses the sewed fabric moving device that the present invention the 1st embodiment is arranged, and Fig. 2 is the sectional view (I of Fig. 1-I cutaway view) of this Sewing machines.This Sewing machines possesses sewing machine frame 1 is arranged, the head of sewing machine 2 of a plurality of (being 4 among the figure), have shuttle seat (shuttle race) 3, the sewed fabric moving device 5 of the rotating shuttle 4 corresponding with each head of sewing machine 2.Sewed fabric moving device 5 comprises: be arranged to the laterally a pair of base material 6,6 of (hereinafter referred to as " directions X ") slip of relative sewing machine frame 1; And can be rotated to support on a pair of rotary body 17,17 on this a pair of base material 6,6 respectively. Rotary body 17,17 is towards direction of rotation (hereinafter referred to as " Y the direction ") rotation of the central shaft that extends around directions X.In addition, in the following description,, be the occasion of the some implications in the left and right sides except having explained it clearly for being arranged to symmetrical a pair of member with prosign, the pairing left and right member is promptly represented in the explanation that lists side's member.
As shown in Figure 2, base material 6 is to have with equally spaced three directions substantially planar member of the arm 6a that extends of the mind-set outside therefrom.Supporting the timing belt pulley 16 that periphery is formed with not shown tooth at the top of each arm 6a axle.The periphery of base material 6 is being provided with the circular ring-type rotary body of rotatably being supported by each timing belt pulley 16 17.As shown in Figure 1, two base materials 6,6 have predetermined distance ground and are configured on directions X, interconnect with many connecting rods 7.As shown in Figure 2, near the center of base material 6, be formed with the through hole of using for the lower bearing bracket 1a break-through of sewing machine frame 18.Be fixed with base station 9 in the upper end of through hole 8.
Fig. 3 is the front view of expression left side base material 6 and periphery thereof for the front view of expression right side base material 6 and periphery thereof, Fig. 4.In these figure, base material 6 is represented with section.Base station 9 can engage with lower bearing bracket 1a along directions X sliding freely by sliding drive mechanism 10.Sliding drive mechanism 10 is made of guide rail 11 that is fixed in lower bearing bracket 1a upper side and the slide block 12 that is fixed in base station 9 downsides and slidably combine with guide rail 11 freely.Again, be fixed with movable block 14 on the base material 6 on right side, this movable block 14 screws togather with screw rod 13.The motor reel of top X drive motor 15 is connected near axially the extending along directions X of screw rod 13, right-hand member and the right side of being fixed in lower bearing bracket 1a.The combination of these base materials 6, X drive motor 15 etc. is equivalent to make described a pair of rotary body 17 relative head of sewing machine 2 and the shuttle seat 3 corresponding with it and the slide mechanism that slides on the transverse width direction of sewn object H.
Fig. 5 is for amplifying the stereogram of a part of representing rotary body 17, and Fig. 6 is the cutaway view of rotary body 17.In addition, in Fig. 5, for convenience of explanation, the part of rotary body 17 and retaining member described later 23 is cut, the section of these members is also made diagram.Rotary body 17 forms circular ring-type with certain width, is formed with synchronous belt 18 with the tooth of the tooth of each timing belt pulley 16 engagement at the inner face that attaching in interior week of this rotary body 17.Thus, rotary body 17 is supported under the state that synchronous belt 18 and each timing belt pulley 16 mesh.On the other hand, as Fig. 2 ~ shown in Figure 4, on an arm 6a who extends below the base material 6, be fixed with Y drive motor 19.On the motor reel of Y drive motor 19, be fixed with drive pulley 20.On the rotating shaft of the timing belt pulley 16 that an arm 6a axle that is subjected to extending supports, be fixed with driven pulley 22 downwards again.And, between drive pulley 20 and driven pulley 22, hanging synchronous belt 21.Like this, in case drive Y drive motor 19, then timing belt pulley 16 rotations, rotary body 17 is rotated.In addition and since about Y drive motor 19,19 be fixed to mutual rotating shaft and be reverse form, therefore, be controlled to equivalent and be reverse rotation mutually, the result is that a pair of rotary body 17,17 synchronously is rotated control with same direction.Above-mentioned Y drive motor 19, drive pulley 20, driven pulley 22, synchronous belt 21, timing belt pulley 16 etc. have constituted the rotary drive mechanism 30 that makes rotary body 17 rotations.
As shown in Figure 5, the periphery at rotary body 17 is fixed with retaining member 23.Retaining member 23 forms the circular ring-type of certain width, is fixed on the inboard of rotary body 17 inboard end limit standing shape.And the outside of the inboard ledge of left-hand tools body 17 is formed with section and is semicircular substantially recess 23a on the whole circumference.As shown in Figure 6, chimericly in recess 23a be used to the card that card ends sewn object H and end member 24.It is the rounded rope form members of section that for example are made of the elastic component of polyurethane rubber etc. that card ends member 24.
Fig. 7 is the figure of the part of amplification presentation graphs 2, and Fig. 8 is the stereogram of the part of the component parts of expression sewed fabric moving device 5.As shown in these figures, the periphery at shuttle seat 3 is provided with the supporting member 25 that is fixed in sewing machine frame 1.Supporting member 25 is made of the tabular component that forms the planar basic rectangle of circular arc, below the sewn object H that is kept by a pair of rotary body 17,17 and be arranged on the periphery of shuttle seat 3.Again, corresponding with shuttle seat 3 position is provided with the peristome 25a that makes shuttle seat 3 expose usefulness.Thus, supporting member 25 can be from the sewn object H supporting of following side with the sewing position periphery.And limit, the front and back end 25b of supporting member 25 is crooked slightly downwards.Like this, when sewn object H faces the Y direction and moves on supporting member 25, because of not hooked, so sewn object H can successfully move in the same direction by end limit 25b.
In addition, the concrete shape of supporting member 25 is not limited to above-mentioned example certainly, can be the arbitrary shape outside above-mentioned.For example, also can on directions X or Y direction, be divided into the shape of a plurality of members.Again, also can be by making a certain at least member of cutting apart removable, so that the area of supporting sewn object H part can enlarge, dwindle.And supporting member 25 is not if need then can omit the setting of this member yet.
In the sewed fabric moving device 5 of said structure, for sewn object H is kept, the end limit (end) of (transverse width) direction that makes the cloth of sewn object H wide is positioned on the recess 23a of retaining member 23, as shown in Figure 6, the side will block and end member 24 and in turn be pressed among the recess 23a and chimeric along the circumferencial direction of rotary body 17 from it.Thus, sewn object H is maintained along the outer peripheral face of a pair of retaining member 23,23, the state of sprawling into cylinder planar (crooked planar) between this a pair of member.
Like this, under the state that uses a pair of rotary body 17,17 that sewn object H is kept, in case drive X drive motor 15, screw thread by screw rod 13 is sent action to, the a pair of base material 6,6 that is connected bar 7 connections slides towards directions X integratedly, thereby the rotary body 17 and the retaining member 23 that are bearing on the base material 6 are slided towards directions X, and sewn object H transfers towards directions X.On the other hand, if drive Y drive motor 19, then rotary body 17 and retaining member 23 one rotation, thus sewn object H is transferred towards the Y direction.As a typical example, according to the sewing pattern of wanting sewn object H is implemented, drive X drive motor 15 according to the X width data of 1 stitching, drive Y drive motor 19,19 according to the Y width data of 1 stitching.
Adopt this sewed fabric moving device 5, use rotary body 17 and retaining member 23 sewn object H can be sprawled barrel surface (flexure plane) shape that is held in along the direction of rotation of rotary body 17, under this state, carry out the handover of sewn object H.Thus, sewn object H is keeping certain flexibility with its surface and is transferring towards directions X, Y direction.Therefore, just can as the sewed fabric moving device that in the past had a plurality of rollers, the flexibility of sewing position and periphery thereof be changed along with the handover of sewn object.Like this, because of the sewn object that can prevent sewing position and periphery thereof effectively takes place to relax, so can not cause the style dislocation of making.
Again, by supporting member 25 is set, be rotated body 17,17 be held in the planar sewn object H of cylinder can be supported along this barrel surface, therefore, even the occasion of stretching sewn object H between rotary body 17,17 can prevent effectively that also the sewn object H of sewing position and periphery thereof from taking place lax.Can successfully use rotary body 17,17 to carry out the handover of sewn object H again.
Again, in the present embodiment, use retaining member 23,23 that the limit, cloth cross direction two ends (both ends) of sewn object H is kept, but also can be on this basis again the limit, cloth length direction two ends of sewn object H be kept.Expression is as the occasion one example, that be provided with a pair of maintenance bar 26,26 among Fig. 8.A pair of maintenance bar 26,26 extends towards directions X with the state that is spaced from each other predetermined distance on the Y direction, is erected between a pair of retaining member 23,23.Keep setting up the cloth clip 27 that is useful on clamping sewn object H on the bar 26 at each again.Cloth clip 27 will be in a part that keeps the sewn object H on the bar 26 being held in it and keeping between the bar 26.Utilize this a pair of maintenance bar 26,26 and cloth clip 27,27 that the limit, cloth length direction two ends of sewn object H is kept.In addition, a pair of maintenance bar 26,26 mutual isolating partitions be arranged to preferably that the operator stretches out one's hand can be by such width between these both members.Like this, even sewn object H is being sprawled when remaining on the sewed fabric moving device 5,, just can exchange the bottom line that is placed in the rotating shuttle 4 by hand being stretched between the maintenance bar 26,26 as long as keep bar 26,26 to be positioned at the place ahead of shuttle seat 3.In addition, the occasion when the limit, cloth length direction two ends that there is no need to keep sewn object H also can be omitted and keeps bar 26 and cloth clip 27.
[the 2nd embodiment]
Sewing machines to the sewed fabric moving device that relates to the present invention the 2nd embodiment describes below.In addition, in the accompanying drawing and explanation thereof of the 2nd embodiment, with the general part mark prosign of the 1st embodiment, the detailed description of omitting this part.Again, for the item beyond the item of following explanation, identical with the 1st embodiment.
Fig. 9 is the Sewing machines front view that relates to the 2nd embodiment, and Figure 10 is the sectional view (II of Fig. 9-II cutaway view) of this Sewing machines.The head of sewing machine that Sewing machines possessed 2 of above-mentioned the 1st embodiment and shuttle seat 3 are a kind of structures that do not move on directions X relative to sewing machine frame 1.By contrast, 34 of the head of sewing machine that Sewing machines possessed 33 of present embodiment and shuttle seats be a kind of relative sewing machine frame (upper spider 31 and lower bearing bracket 32) but one is slided on directions X structure.
Describe now this structure in detail, each head of sewing machine 33 that Sewing machines possessed of present embodiment is fixed on two installing plates 36,36, and each installing plate 36 engages towards directions X sliding freely along the rail plate 37 that is fixed in upper spider 31 fronts.Thus, each head of sewing machine 33 can slide towards the directions X one.Again, as shown in figure 10, be fixed with forwards horizontal outstanding flat substantially base station 38, above the base station 38, be fixed with track base 40 by studding 39 at this in the front of lower bearing bracket 32.On the other hand, each shuttle seat 34 is fixed on the installing plate 41, and installing plate 41 engages towards directions X sliding freely along the rail plate 42 that is fixed in track base 40.Thus, each shuttle seat 34 also slides towards the directions X one and moves.
And, as shown in Figure 9, between installing plate 36 and installing plate 41, the connecting plate 43 that is used to be connected these members is installed.Connecting plate 43 is the plate-like members that laterally form basic U word shape, is fixed on an end front of installing plate 36 and installing plate 41.Be provided with color replacing mechanism 44 in the front of connecting plate 43, this color replacing mechanism 44 can make the shank box of head of sewing machine 33 move and be disposed at the position of having selected suture needle.In addition, color replacing mechanism 44 is because of being the known configurations that Sewing machines possessed in the past, so omit detailed explanation at this.
Be provided with the sliding drive mechanism 45 that is used to drive connecting plate 43 again.As shown in figure 10, sliding drive mechanism 45 is installed in the front of plate 46 set between upper spider 31 and the lower bearing bracket 32, as shown in Figure 9, comprising: with respect to the supported freely ball screw of being fixed on the plate 46 48 of framing component 47 rotations; Be fixed on the back side of connecting plate 43 and screw togather the movable block 49 of ball screw 48; And the drive motor 50 that is used to make ball screw 48 rotations.Thus, when drive motor 50 is driven, send under the action, by connecting plate 43 installing plate 36 and installing plate 41 are slided towards directions X, thereby head of sewing machine 33, shuttle seat 34 and color replacing mechanism 44 are slided towards the directions X one at the screw thread of ball screw 48.The function that these members 36,37,41,42,43 have as connecting portion can connect into relative sewing machine frame 31,32 form that one is slided on the transverse width direction of sewn object H with head of sewing machine 33 and with its corresponding shuttle seat 34.Again, the combination of these members 36,37,41,42,43 and sliding drive mechanism 45 etc. is equivalent to make head of sewing machine 33 and corresponding shuttle seat 34 slides with it slide mechanism on the transverse width direction of sewn object H.
Figure 11 is the stereogram of the right-hand end of expression sewed fabric moving device 51.The sewed fabric moving device 5 of the 1st embodiment has the base material 6 that can slide on directions X, rotary body 17 can not only be rotated action (the Y direction moves), also can it be slided towards directions X by base material 6.By contrast, the sewed fabric moving device 51 of the 2nd embodiment is because of having omitted base material 6, and rotary body 17 can only be rotated action (the Y direction moves), does not slide on directions X.
Describe now this structure in detail, three timing belt pulleys 16 that sewed fabric moving device 51 is possessed axle respectively are bearing in the bracket 52 that is fixed in above the lower bearing bracket 32, are fixed in the bottom bracket 53 below the lower bearing bracket 32 and are fixed in by pillar 32a on the motor bracket 54 of lower bearing bracket 32 fronts.On motor bracket 54, be fixed with Y drive motor 55, on the motor reel of Y drive motor 55, be fixed with driven wheel 56.And, be bearing at axle on the rotating shaft of the timing belt pulley 16 on the motor bracket 54, be fixed with driven gear 57 with driven wheel 56 engagements.Thus, in case drive Y drive motor 55, then axle is bearing in timing belt pulley 16 rotations on the motor bracket 54 and makes rotary body 17 rotations.Above-mentioned Y drive motor 55, driven wheel 56, driven gear 57, timing belt pulley 16 etc. have constituted the rotary drive mechanism 70 that makes rotary body 17 rotations.
In this sewed fabric moving device 51, use rotary body 17 that sewn object H is kept, when driving Y drive motor 55, rotates by making rotary body 17 and retaining member 23, sewn object H is rotated and transfers towards the Y direction.On the other hand, when driving drive motor 50, head of sewing machine 33, shuttle seat 34 and color replacing mechanism 44 relative rotary bodies 17 slide towards the directions X one.Like this, sewn object H is that rotation by rotary body 17 is carried out with respect to head of sewing machine 33 and shuttle seat 34 towards relatively moving of Y direction, then is to be undertaken by the slip of head of sewing machine 33 and shuttle seat 34 towards relatively moving of directions X.
Again, sewed fabric moving device 51 has the supporting member 25 variform supporting members 58 with the 1st embodiment.Supporting member 58 is and the primary circle barrel shape of rotary body 17 basic identical diameters, is configured between a pair of rotary body 17,17, is fixed on the lower bearing bracket 32.Supporting member 58 with each shuttle seat 34 part in opposite directions, be provided with to be cut into the otch 58a of linear strip along directions X with shuttle seat 34 essentially identical width.Again, be formed with aperture 59 on the position corresponding with each shuttle seat 34 the place ahead, this aperture 59 is used for exchanging the bottom line that is placed on each rotating shuttle 35.
Adopt the supporting member 58 of this shape, supported from the inboard along this barrel surface, therefore, successfully carry out the handover of sewn object H by the energy of rotation of rotary body 17 owing to use rotary body 17,17 will sprawl to be held in the planar sewn object H of cylinder.Particularly supporting member 58 is because of forming the primary circle tubular, so can be at almost complete all upper support sewn object H of circumferencial direction.Again, though between a pair of rotary body 17,17 occasion of stretching sewn object H, can prevent effectively that also the sewn object H of sewing position and periphery thereof from taking place lax.
