Description

Wrapped foot nail button sewing machine

Technical field

The present invention relates to a kind of Wrapped foot nail button sewing machine.

Background technology

In the past, at automatic nail catcher (below deserve to be called button) on the dress material, the sewing thread between upper button and dress material (the to call the root line in the following text) Wrapped foot nail button sewing machine of kinking sewing thread on every side is as you know again.The Wrapped foot nail button sewing machine in past, at workbench etc. the XY feed arrangement is installed partly, by this XY feed arrangement, when dress material and upper button are carried together, shank move up and down and the coordinated movement of various economic factors of the binding-off machine of workbench inside under, buttoning is buckled on dress material.In addition, as other example, for example shank is done the swing of directions X, and dress material and button are done the feeding of Y direction, and dress material and upper button are done the feeding of XY direction with respect to shank like this.

Yet aforesaid upper button and dress material be the pattern of feeding together, produces various restrictions, can not fully adapt to the diversified requirement of making, and for example has the described problem in following (1)-(3).

(1) on clothes such as overcoat, when nailing on button, how to follow closely the end that adds simultaneously and buckle in the inboard of dress material.End button is smaller compared with upper button, so generally speaking, upper button and end button, the size of buttonhole, buttonhole spacing are all different.But the Sewing machines in the past that last lower button and dress material are carried together, last button that the buttonhole spacing is different and end button are clamped under the state of dress material, and nail catcher is impossible simultaneously.Therefore, once specially made the end button the same, and make with it, but in fact almost all be manual making, thereby operation was very poor with the buttonhole of upper button.

For addressing the above problem, Ceng Zaite opens and has delivered on the flat 8-117465 patent gazette to independently carrying the upper button and the end to buckle respectively, and the Sewing machines of 2 XY worktable is set.But 2 XY worktable so are set, and when driving the two, not only vibration and noise are very big, and the quantitative change of Sewing machines gross weight is big, and be less practical.Moreover XY worktable only could move when sewing needle pulls up, and just can only do intermitten, so limited on the high speed.

(2) on dress material during nail catcher, for the purpose of good-looking, the position of the pin that falls on dress material preferably concentrates on a place.In other words, during manual nail catcher, shown in Figure 19 (a), the pin that on dress material S, almost falls in same place, kinking under such state, shown in Figure 19 (b), the root line that connects from dress material is in line, and seems good-looking.

But with Sewing machines nail catcher in the past, the relative position relation of upper button and dress material is the same all the time, so the buttonhole spacing of upper button is exactly a needle downing position on the dress material.That is to say, shown in Figure 19 (c), the sewing thread that button B links to each other with dress material S, corresponding buttonhole spacing W becomes parastate, and after the kinking, shown in Figure 19 (d), about the kinking part, sewing thread is tubaeform, seems plain.

In addition, the position of the pin that falls on dress material is according to circumstances, staggers a little sometimes.For example, nail catcher is made beginning or when finishing, and at the same buttonhole continuous several times pin that falls, but for avoid repeatedly falling pin and damage dress material on the identical position of buttonhole, pin falls on the slightly different position of same buttonhole.The former situation, also no problem with Sewing machines in the past, but the latter's situation must have problem.Buttonhole diameter 2mm for example, the pin diameter of sewing is 1mm, there is 0.5mm the position that eedle staggers in the calculating, in fact have only 0.3mm.Therefore, with Sewing machines in the past, in a buttonhole, it is difficult that the position of moving dress material connects perverse.

(3) general, during the upper button of operation Wrapped foot nail button, connect the root line of upper button and dress material by hand, be not exposed at the dress material inboard, but in order to have intensity, only a pin is by the dress material inboard.Should be called " line feeder " by the line of dress material inboard, upper button be made firmly on dress material, carry out kinking then with it.

On the other hand, when Sewing machines Wrapped foot nail button is in the past arranged, shown in Figure 20 (a), above the dress material S that folds up, button B costs under the state of half earlier, when buttonhole h1 falls pin, at dress material decline pin, when buttonhole h2 fell pin, pin did not fall on dress material, the former claims " taking pin ", and the latter claims " empty needle ".If take pin and empty needle repeatedly, form root line T between button B and the dress material S, cut off sewing thread then.

Then shown in Figure 20 (b), the direction of button B turn 90 degrees.Under this state, around root line T, twine sewing thread.At this moment, the pin amount in the kinking is as line feeder t, by the inboard of dress material S.Line feeder when the line feeder t here stitches with original hand is different, is not that button B is connected the root line T that links up with dress material S, only on the root line, so weak strength.By Figure 20 (a) when making, if can mobile dress material S, the root line be as line feeder, but Sewing machines in the past, the position relation of dress material and button is fixed, so this is impossible.

In addition, put down in writing on the special open 2-45913 communique, when making the root line, move dress material, form line feeder, but can only move a certain distance with cylinder, and if the sewing conditions such as size of toggle change, operation is regulated by hand, and is very inconvenient.

Except (1)-(3), the Wrapped foot nail button sewing machine in past, the problem below also having.Make in the flowing water production of factory, when making nail catcher, on dress, make multiple button, for example, on a cover western-style clothes, be mixed with as shown in figure 20 " tower pin kinking is made ", only take " taking pin presses close to make " of pin sewing, " be with the end buckle make " of (buckle at the end) nail catcher etc. buckled in the upper button that is arranged above and below, dress material, reinforcement.Up to the present, make the machine that special use is all arranged for every kind.Therefore, when making a suit of clothes, every kind of nail catcher all will be lifted down dress material, upward arrives special purpose machinery, carries out these operations repeatedly, and operator's manual operations is a lot, and operating efficiency is low.In addition, to every kind of nail catcher kind, purchase corresponding special purpose machinery, this needs a large amount of equipment investments.

Summary of the invention

The purpose of this invention is to provide a kind of Wrapped foot nail button sewing machine, it can be carried button and dress material respectively, can adapt to multiple sewing condition, can improve operating efficiency.

In order to achieve the above object, the present invention's 1 described Wrapped foot nail button sewing machine as Fig. 1-shown in Figure 17, is characterized in that having:

The shank 9 of sewing needle 5 is loaded onto in the bottom, under the effect of slightly horizontally disposed main shaft 7, the pin up-down drive device that can drive up and down (pin is actuation mechanism 10 up and down) and,

In the plane of or orthogonal parallel to vertical one-tenth of main shaft, make pin pendulum drive unit (needle swinging mechanism 11) that shank can swing and,

But the cloth feeding plate (lower plate 56) of sewing piece of button at the bottom of the top mounting, the cloth feed drive unit (following Y feed mechanism 50) that on the direction of the pin pendulum direction phase orthogonal of pin pendulum drive unit, drives and,

Level is slightly controlled the upper button clamping part (clamping part 90) of upper button, parallel with the cloth direction of feed of cloth feed drive unit the first button drive unit (going up Y feed mechanism 30) that drives on the direction and,

The upper button clamping part becomes orthogonal at the driving direction of the first button feed drive unit, and parallel with pin pendulum direction second button that direction drives and feed drive unit (button differential attachment 70) and,

The control device (CPU 102) of described each drive unit of control.

According to above-mentioned Wrapped foot nail button sewing machine, sewing needle with the plane of main shaft parallel longitudinal or orthogonal in, do oscillating motion by pin pendulum drive unit, for upper button, by the first button feed drive unit, the direction identical with the cloth direction of feed moves; By the second button feed drive unit of phase orthogonal therewith, the direction identical with pin pendulum direction moves.For end button and dress material, by the cloth feed drive unit, with pin pendulum direction mutually the direction of orthogonal move.If utilize the oscillating motion of sewing needle, end button and dress material are for upper button, and the direction that can do with respect to cloth feed drive unit phase orthogonal moves.In other words, can move on the both direction that upper button and dress material (buckle at the end) are kept straight in horizontal plane respectively mutually.Therefore, make up these drive units, the result can freely change the relative position relation of upper button, dress material (buckle at the end), makes that impossible various nail catchers become possibility in the past.

As mentioned above, upper button, dress material (buckle at the end) can move freely on the both direction of keeping straight on mutually respectively, and for end button, owing to utilize needle swinging mechanism, the situation that 2 XY worktable drivings were set with the past is compared, and can reduce gross weight.In addition, the waving of shank, XY worktable moves, all just moves when sewing needle exceeds the needle plate top position, in any case, though be intermittent movement, on reality constitutes, the oscillating motion of shank than driving work with soon, institute runs at high speed and becomes possibility, the operating efficiency height.

The present invention's 2 kinking pin Sewing machines, for example shown in Figure 180, it is characterized in that having:

The shank of sewing needle is equipped with in the lower end, under the effect of slightly horizontally disposed main shaft, up and down the pin up-down drive device of Qu Donging and,

In the plane of or orthogonal parallel to vertical one-tenth of main shaft, make pin pendulum drive unit that shank can swing and,

But button at the bottom of the top mounting with make the cloth feeding plate of thing, the cloth feed drive unit that drives on the direction of orthogonal mutually with the pin pendulum direction of pin pendulum drive unit and,

The level of omiting is controlled the upper button clamping part of upper button, parallel the first button feed drive unit that drives on the direction and upper button clamping part driving direction orthogonal in the cloth direction of feed of cloth feed drive unit at the first button feed drive unit, and parallel with pin pendulum direction in the second button feed drive unit that direction drives any one and

Control the Wrapped foot nail button sewing machine of the control device of described drive unit.

According to above-mentioned invention, sewing needle is put drive unit by pin, does oscillating motion in the plane to main shaft parallel longitudinal or orthogonal.For on drive button, by the first button feed drive unit or the second button feed drive unit, can with cloth direction of feed or pin pendulum direction equidirectional on move.For end button and dress material, by the cloth feed drive unit, can with the direction of pin pendulum direction orthogonal on move.

In other words, upper button, dress material (buckle at the end), sewing needle can drive on direction separately respectively, so these devices are combined, can freely change the relative position relation of upper button, dress material (buckle at the end) to a certain extent, make that impossible various seam buttons become possibility in the past.

The present invention's 3 Wrapped foot nail button sewing machine, be in 1 or 2 described Wrapped foot nail button sewing machines of foregoing invention, it is characterized in that described cloth feeding plate keep making the state of thing bending, can take the pin sewing cloth holder portion (cloth holder portion 60, position A) and
