In addition, CPU 121 is connected with X feeding pulse motor driver 126, simultaneously, be connected with Y feeding pulse motor driver 128, drive X feeding pulse motor 127 and Y feeding pulse motor 129 on one side, on one side when making etc., drive into to platform 13 at directions X and Y-direction.
In addition, CPU 121 is connected with sewing machine electromotor driver 132, drives the rotation of control sewing machine electromotor 133.Thus, can carry out synchronously moving up and down and the reciprocating action of the prescribed direction of needle swinging motion and looper of needle bar 11 (suture needle 18).
Use the relation of action of the each several part of stitching that Figure 16 makes for lock seaming and button hole Sewing machines 10 to describe here.Lock seaming around the H of button hole is made, carries out according to following order as shown in figure 16, that is, and from the end W2 that the J1 of section is made on the right side, around the h1 of round end section, until the J2 of section is made in the left side.On the other hand, feeding platform 13 is driven when making, and moves to over the ground needed position under the suture needle 18 so that load in the phase of making on the feeding platform 13.
That is to say, if make beginning, then feeding platform 13 on Y-direction from origin position (make beginning before and after the position of feeding platform 13), move to and make starting position (needle downing position of suture needle 18 becomes the position of the feeding platform 13 of W2 shown in Figure 16), then, move up at fore-and-aft direction, right and left and to make to lockstitch a border according to aforementioned order, return roughly identical with making starting position sewing finishing position, then, movement is back to initial origin position.In addition, on left and right directions, utilize for example needle swinging motion of the suture needle 18 of amplitude of fluctuation x, by the position change of amplitude of fluctuation x, it is mobile at the directions X of feeding platform 13 to make stitching form the position.
In addition, when making the J1 of section formation on the right side, as shown in figure 16, be controlled to be so that the upper thread end T1 that is kept by threading clamping device 50 sews up in the stitching.For this control as described later.
In addition, feeding platform 13 makes and makes thing and move to the opposite direction that forms direction with stitching shown in Figure 16.Therefore, making of making of Buttonhole when when beginning, the formation of the J1 of section was made on the right side, feeding platform 13 makes that to make thing forwards mobile.On the other hand, thread-clamping device 50 is positioned at the rear of needle bar 11.That is to say that thread-clamping device 50 is with respect to needle bar 11, be positioned at an opposite side (rear side shown in each figure) that is made the direction (front side shown in each figure) of making the thing feeding when making beginning by feeding platform 13.
In addition, CPU 121 controls driving via 134 pairs of aforementioned upper and lower air cylinders 73 of upper and lower air cylinders driver, controls driving via 136 pairs of clamping cylinders 65 of clamping cylinder driver, via the decompression degree of pressure-reducing valve driver 137 control pressure-reducing valve 68a.
In addition, CPU 121 is connected with upper line tension solenoid 139 and lower line tension solenoid 140 via line tension driver 138.These solenoids 139,140 constitute, and can utilize the automatically controlled tension force that makes variable, and CPU 121 control line tension force make it become setting value in the guidance panel 100.
(being moved by the clamping of reaching the standard grade that thread-clamping device carries out)
As mentioned above, in buttonholing machine 10, if feeding platform 13 with sewing finishing the mode of returning origin position from the sewing finishing position move.At this moment, reach the standard grade and roll off the production line for the state of making phase and connecting, these lines are all along with making moving of thing and be drawn out on the feeding platform 13.This movement of making backward initial point is called the sky feeding.In the process of this sky feeding, utilize clamping section 54 to clamp and reach the standard grade the cut-out of to reach the standard grade in the front and back of this clamping.
For these regularly, describe according to the Figure 10 that schematically represents feeding platform 13 state on every side with the state that omits feeding platform 13.
S is the thing of making on the feeding platform 13, and T reaches the standard grade, the 40th, have the needle plate of pin hole, and the 41st, wire grip, the 42nd, looper device, the 43rd, the cutting knife of reaching the standard grade (cutting unit of reaching the standard grade).The T that reaches the standard grade that suture needle 18 after sewing finishing is drawn, pass at final needle downing position W1 place and to make thing S and insert in the needle plate 40, around wire grip 41, looper device 42, again from needle plate 40, extract, then near the needle downing position W1 to upper surface out.
On the other hand, clamping section 54 is positioned at the position of slightly close initial point with respect to suture needle 18 in Y-direction, when being positioned at the position of readiness of regulation, for example highly be H, when T is reached the standard grade in seizure, by up and down drive division 70 drivings, dropping to for example highly is the clamped position of H '.
As previously mentioned, holding piece 52b, 53b clamping between protuberance 52c and protruding pin 61 T that reaches the standard grade.Move if feeding platform 13 carries out the sky feeding to initial point, it is also mobile together then to make thing S.Thus, as shown in figure 10, the T that reaches the standard grade is also mobile with making thing S, and pulls out from suture needle 18 with being tilted.Thus, the T that reaches the standard grade is 54 close to the clamping section, and then enters between protuberance 52c and the protruding pin 61, and in this state, if closed between holding piece 52b, the 53b, the T that then reaches the standard grade is clamped.The T that reaches the standard grade before and after this clamping cutting knife 43 of being reached the standard grade cuts off, and then, rise and return position of readiness (height H) in clamping section 54.
In addition, CPU 121 controls, so that descend correspondingly with the suture needle 18 of making when beginning, makes clamping section 54 to height H ' clamped position decline.Thus, by the formation of stitching upper thread end is sewed up in the stitching.In addition, will remove and reach the standard grade if carried out setting making of pin number after making beginning, then CPU 121 is controlled to be and disconnects electromagnetic valve 68, and holding piece 52b, 53b are unclamped.Thus, upper thread end freely and keeps this state and is naturally sewed up in the stitching.
In the cut situation of the power supply of buttonholing machine 10, because above-mentioned electromagnetic valve 68 is failure to actuate, so can not produce the power of the position of the piston rod 65a that keeps clamping cylinder 65.Therefore, with cut off the electricity supply before the location independent of piston rod 65a of clamping cylinder 65, holding piece 53b utilizes torsion-coil spring 57 to clamping cylinder 65 side pretensions, thus holding piece 52b, 53b become the state that unclamps.If connect the power supply of buttonholing machine 10, then CPU 121 protrudes piston rod 65a by electromagnetic valve is connected, thereby control becomes the state that makes holding piece 52b, 53b closure.
Because the switching of the holding piece 52b, the 53b that are caused by the switching of electric power on/off is above-mentioned control, so, even wish at the upper thread end of for example changing after making the 51 maintenance replacings of line clamping part when reaching the standard grade, also because if when reaching the standard grade replacing, disconnect the power supply of buttonholing machine 10, then holding piece 52b, 53b become the state that unclamps, so holding piece 52b, 53b can not clamp suture.On the other hand, if under the state of the power supply of connecting buttonholing machine 10, reach the standard grade replacing, then because holding piece 52b, 53b are closed, reach the standard grade between holding piece 52b, 53b so can't make.
Therefore, in the buttonholing machine that the present invention relates to, the whether closed other maintaining part of reaching the standard grade (tangent line holding plate 69) of reaching the standard grade of all can keeping of no matter holding piece 52b, 53b is set.Below, be elaborated for tangent line holding plate 69.
(tangent line holding plate)
As shown in figure 11, tangent line holding plate 69 has two 69a of hole section, 69a in that one is distolateral, passes this hole 69a, 69a by making screw 59,59 threaded portion, and as mentioned above, tangent line holding plate 69 is fixed on the extension 55c that clamps holding plate 55.At this moment, shown in Fig. 5,6, tangent line holding plate 69 is fixed in the mode between the extension 55c that clamps installing plate 55 and screw 59,59 head of screw.
In addition, shown in Fig. 6 (a), (c), Figure 11 and Fig. 7 (a), (b), tangent line holding plate 69 is flat spring, and it forms, under the state that is fixed on the extension 55c, be shaped as roughly S font in the situation of top view buttonholing machine 10.Tangent line holding plate 69 utilizes its elasticity to carry out pretension, so that the planar portions with blade part 69c described later is pressed on the side, right side of online clamping part 52.Thus, the end of reaching the standard grade can be sandwiched and remains between the side, right side and this planar portions of line clamping part 52.
In addition, the end (another end) that is positioned at lower side when tangent line holding plate 69 is fixed on the extension 55c arranges return portion 69b, and it arranges predetermined angular with respect to the planar portions with blade part 69c.The predetermined angular of return portion 69b is set to, under tangent line holding plate 69 is fixed on situation on the extension 55c, to from the side, right side of line clamping part 52 away from direction extend.Thus, in the time will making the end of reaching the standard grade sandwich and remain on the side, right side of line clamping part 52 and to have between the planar portions of blade part 69c, thread end is imported from the below and sandwich.
In addition, by the elasticity of tangent line holding plate 69 confining force of reaching the standard grade is set to following degree in advance, that is, by making in the process that upper thread end is sewed up, by being pulled downwards by the upper thread end that tangent line holding plate 69 keeps, can be pulled out reaching the standard grade.Thus, even in the making of carrying out at first after changing of reaching the standard grade, also can with by the switching of holding piece 52b, 53b to the maintenance (clamping) of upper thread end/unclamp similarly, upper thread end is sewed up in the stitching.
In addition, shown in Fig. 6 (c), Figure 11 and Figure 12 described later (a), (b), tangent line holding plate 69 becomes a side in the place ahead when tangent line holding plate 69 is fixed on the threading clamping device 50 lateral margin arranges blade part 69c.Can utilize blade part 69c to cut off reaches the standard grade.
Utilizing blade part 69c to cut off in the situation of reaching the standard grade, shown in Figure 12 (a), after the planar portions of forwards utilizing line clamping part 52 and having a blade part 69c at the rear from buttonholing machine 10 sandwiches the T that reaches the standard grade, shown in Figure 12 (b), rearward draw by the upper thread end T1 that will forwards extend, the T that will reach the standard grade upward cuts off by being pressed in blade part 69c.Thus, the end of reaching the standard grade is shortened, thereby upper thread end is sewed up in the stitching.
(action of Sewing machines)
The clamping of reaching the standard grade that comprises of expression buttonholing machine 10 is processed in the interior flow process of making action in Figure 13.
This processing begins by operation start switch 125.At first, in step S 1, drive sewing machine electromotor 133 grades and begin Buttonhole and make.Then, in step S2, upper and lower air cylinders 73 is connected, made the clamping part 51 of reaching the standard grade drop to clamped position from the position of readiness of top.
In addition, timing that suture needle 18 descends from from top dead-centre to bottom dead centre is compared with making beginning among the step S1, the clamping part 51 of reaching the standard grade arrive clamped positions timing can with its roughly simultaneously, also can be more Zao than its summary.If suture needle 18 begins to make, then clamped 54 reaching the standard grade of clamping will be sewed up in the stitching naturally.
Then, in step S3, monitor whether to reach to be set as the pin number (setting the pin number) that clamping section 54 releasings are reached the standard grade that if arrive, then in step S4, electromagnetic valve 68 is disconnected, holding piece 52b, the 53b of clamping section 54 unclamp.Thus, line end is decontroled, and keeps this state and naturally sew up in the stitching.
Then, in step S5, upper and lower air cylinders 73 is switched to off-state, make the clamping part 51 of reaching the standard grade rise to position of readiness.In addition, at position of readiness, clamping section 54 can be unclamped also can be closed.
Then, in step S6, judge to make and whether finish until sewing finishing, if finish then enter step S7.In step S7, again upper and lower air cylinders 73 to be connected, the clamping 51 of reaching the standard grade drops to clamped position.In addition, in the situation with the state standby of clamping section 54 closures, after unclamping, make its decline.
Then, in step S8, be positioned at easily clamped position in order to make final needle downing position, make feeding platform 13 with the correcting value that sets in the directions X upper feeding, in step S9, beginning feeding platform 13 movement (empty feeding) from the sewing finishing position to initial point.At this moment, mentioned strain also is adjusted to the setting of setting via guidance panel 100.
In step S10, the cut-out of reaching the standard grade at the regulation amount of feeding place that sets in step S11, is judged whether feeding ormal weight and become the timing of clamping of feeding platform 13, if be judged to be feeding, then enters step S12.In step S12, clamping cylinder 65 becomes on-state, the clamping of will reaching the standard grade, and then, in step S13, upper and lower air cylinders 73 disconnects, and the clamping part 51 of reaching the standard grade rises.In step S14, carry out other and make subsequent treatment (such as rear cutting knife processing etc.), finish this flow process.
In addition, reaching the standard grade of step S10 cut off regularly and the clamping of step S12 timing, becomes one in front and one in back by setting.
In addition, in the situation when reaching the standard grade making of carrying out at first after changing, power supply at buttonholing machine 10 is cut off under the state of (unclamp clamping section 54), before step S1, the operator sandwiches and remains on by the end of manually will reaching the standard grade between the side, right side and tangent line holding plate 69 of line clamping part 52, uses blade part 69c to cut off unnecessary thread end.Then, if connect the power supply of buttonholing machine 10, the processing after the beginning above-mentioned steps S1 then in step S2, by reaching the standard grade that tangent line holding plate 69 keeps, is sewed up in the stitching naturally.Then, in step S4, unclamp the moment of clamping section 54, sew up by reaching the standard grade and the upper thread end that kept by tangent line holding plate 69 is pulled downwards, between tangent line holding plate 69 and line clamping section 52, pull out.Thus, can carry out and in step S4, electromagnetic valve 68 is disconnected, will reach the standard grade and unclamp same making by the holding piece 52b, the 53b that unclamp clamping section 54.
(action effect that is obtained by the buttonholing machine of the 1st embodiment)
According to above-mentioned embodiment, tangent line holding plate 69 be fixedly installed on threading clamping device 50 clamping section 54 near be the side, right side of line clamping section 52, tangent line holding plate 69 keeps thread end respectively with clamping section 54.In addition, tangent line holding plate 69 utilizes elasticity to keep upper thread end.That is to say that the action of the clamping cylinder 65 that causes with the on/off by electromagnetic valve 68 of threading clamping device 50 is irrelevant, tangent line holding plate 69 can be near the maintenance clamping section 54 thread end.Thus, even the state that the power supply of buttonholing machine 10 is disconnected, tangent line holding plate 69 also can keep thread end.Therefore, disconnect in the situations such as power supply of buttonholing machine reaching the standard grade when changing etc., as long as make tangent line holding plate 69 keep upper thread end, roughly the same making when carrying out reaching the standard grade T with clamping section 54 maintenances of threading clamping device.That is to say, can break away from from the pin hole of suture needle 18 at when beginning T that suppresses to reach the standard grade of making that Buttonhole is made, simultaneously, can guide so that upper thread end is sewed up in the stitching that lock seaming makes.At this moment, to be dragged to making the thing layback by the upper thread end that tangent line holding plate 69 keeps by upper thread end being sewed up in the stitching that Buttonhole makes, as mentioned above, because utilize this pulling force so that upper thread end breaks away from from tangent line holding plate 69 naturally, so upper thread end can be followed the carrying out that Buttonhole makes and naturally unclamp, and sews up in the stitching.Therefore, can solve the following problems point of existing buttonholing machine, namely, under the state that the power supply of buttonholing machine is disconnected, can not make threading clamping device keep reaching the standard grade, reaching the standard grade breaks away from and can't form stitching from the pin hole of suture needle, or upper thread end is not sewed up in the stitching and sagging, thereby can't form the problem of stitching attractive in appearance, can provide to form the buttonholing machine that better Buttonhole is made.
In addition, tangent line holding plate 69 has the blade part 69c that can cut off suture.Thus, can cut off the part of the upper thread end that is kept by tangent line holding plate 69.Therefore, shown in Figure 12 (b), by when making tangent line holding plate 69 keep reaching the standard grade, cutting off the upper thread end of pulling out from tangent line holding plate 69, can make the pin hole that passes suture needle 18 and become suitable length by the upper thread end that tangent line holding plate 69 keeps.Thus, be that suitable length is lockstitched a border and made because can make the end of reaching the standard grade, so in upper thread end being sewed up the stitching that lock seaming makes the time, can not expose because upper thread end is long, can form stitching more attractive in appearance.
(the 2nd embodiment)
Below, use Figure 14, Figure 15 pair of 2nd embodiment different from above-mentioned the 1st embodiment to be elaborated.In addition, the identical label of structure mark for identical with above-mentioned the 1st embodiment illustrates omission.
The state that unclamp Figure 14 (a) expression clamping section 54, the state of Figure 14 (b) expression clamping section 54 closures.And the protruding pin 61 shown in Figure 14 (a), (b) omits its part for the switching that clearly represents holding plate 69, and in fact, it has the length identical with the protruding pin 61 shown in Fig. 6 (a).
Shown in Figure 14 (b), at the piston rod 65a protrusion that makes clamping cylinder 65 by electromagnetic valve 68 is connected, thereby holding piece 52b, 53b are become in the situation of closure state, among the protuberance 53Ac patchhole 52Ad of section and press the planar portions with blade part of tangent line holding plate 69.At this moment, tangent line holding plate 69 is pressed by protuberance 53Ac, separates with the side, right side from line clamping part 52.That is to say that by pressing of protuberance 53Ac, tangent line holding plate 69 becomes the state that unclamps.Thus, if from the state that upper thread end is kept by tangent line holding plate 69, make clamping section 54 closures, protuberance 53Ac presses tangent line holding plate 69, and then tangent line holding plate 69 is unclamped, and is released by the upper thread end T1 that tangent line holding plate 69 keeps.
And, the 2nd embodiment and above-mentioned the 1st embodiment similarly because in the situation that the power supply of buttonholing machine 10 is disconnected, electromagnetic valve 68 is failure to actuate, so shown in Figure 14 (a), clamping section 54 becomes the state that unclamps.That is to say, holding piece 52b, 53b are worked as " elastomeric element " to the torsion-coil spring 57 that unclamps the direction pretension.
Here, when changing such as reaching the standard grade etc., the power supply of buttonholing machine 10 is disconnected and under the state (Figure 14 (a)) that unclamps clamping section 54, as shown in figure 15, the T that reaches the standard grade is passed between holding piece 52b and the holding piece 53b, be between protuberance 52c and the protruding pin 61, and, make tangent line holding plate 69 keep upper thread end T1.Then, if the power supply of buttonholing machine 10 is switched on, then shown in Figure 14 (b), with clamping section 54 closed interlocks, protuberance 53Ac becomes and presses tangent line holding plate 69 and with its state that unclamps.That is to say that protuberance 53Ac works as " linkage portion ", when it makes the clamping section 54 of the clamping part 51 of reaching the standard grade closed in the action by clamping cylinder 65, remove by 69 pairs of maintenances of reaching the standard grade of tangent line holding plate.Thus, utilize clamping section 54 make by between holding piece 52b and the holding piece 53b, be that the T that reaches the standard grade between protuberance 52c and the protruding pin 61 is clamped, simultaneously, thread end T1 is unclamped from tangent line holding plate 69.Therefore, even making in the operation of reaching the standard grade and begin to carry out after changing, also can be according to the making in the action of above-mentioned flow process shown in Figure 13, by shown in the step S4 with the holding piece 52b of clamping section 54, the operation that 53b unclamps, will reach the standard grade and unclamp.That is to say, even reach the standard grade initial making after changing, also with making similarly afterwards, can based on flow process shown in Figure 13 by the maintenance of reaching the standard grade/unclamp control to make.
(other)
In addition, the present invention is not limited to above-mentioned embodiment certainly, can suitably change.For example, in the 1st embodiment, torsion-coil spring 57 is to the direction pretension that holding piece 52b, 53b are unclamped, but also can be to the direction pretension of closure.In this case, must be set to apply power by the action of clamping cylinder 65 to the direction that holding piece 53b is unclamped.In addition, clamping cylinder 65, upper and lower air cylinders 73 also can be other drive unit (such as solenoids etc.).
