In addition, following roller 50a, 50b have by connecting rod body 58, as seesaw, keep the function of the pressure that contacts with sewn object according to the thick variation homogeneous of cloth, and following roller 50a, 50b are abutted against with the pressure of equalization respectively.
Below, with reference to accompanying drawing, the draw-gear 100 of the Sewing machines of present embodiment is elaborated.
At first, before making the action beginning, upper roller 40 and following roller 50a, 50b together stop, and upper roller 40 remains on the upper/lower positions by supporting mechanism 20.
When making beginning, by known cloth feeding mechanism (omitting diagram) sewn object cloth is transported on the base plate 3, the front end of cloth is clamped between upper roller 40 and following roller 50a, the 50b.
At this, when the thickness of the left and right directions of cloth did not have deviation and is flat condition, as shown in Figure 4, two following roller 50a, 50b were abutted against below identical height and cloth together.And along with the beginning of making action, if action is carried in starting, then upper roller 40 and roller 50a, 50b down rotate on the direction of arrow of Fig. 4, with cloth side conveying downstream.
Then, for example, when only implementing overlapping situation of making etc. in left and right sides any one party with respect to throughput direction, with respect to throughput direction the thick deviation of cloth takes place on left and right directions.In this case, as shown in Figure 5, the thick following roller 50b for a thick side of the cloth of sewn object is pushed downwards.And meanwhile, the following roller 50a of the opposite side that connects by jut 55 and connecting rod body 58 is promoted by side upward.And following roller 50a, 50b are the balanced controls of regulating at the height that the surface pressing to upper roller 40 side effects equates.That is, whether the Sewing machines draw-gear 100 of present embodiment no matter stride left and right directions thickness deviation takes place, and all plays as the effect to the guiding mechanism of the surface pressing of the sewn object even action that is transferred.
In addition, the draw-gear 100 of the Sewing machines of present embodiment, not only making action at first, even the thick variation of cloth in the way of carrying action, on with respect to the left and right directions of throughput direction, take place under the situation of the thick deviation of cloth, move simultaneously by linkage following roller 50 that rises and the following roller 50 that descends owing to being situated between, so, even after just the thick variation of cloth taking place, also can keep uniform surface pressing reliably.
As mentioned above, draw-gear 100 according to the Sewing machines of present embodiment, because roller 50 is made of 2 following roller 50a, 50b arranging at direction of principal axis down, so, roller 50a, 50b move respectively according to the thick variation of cloth down can to make each, across the whole width of the cloth vertical, the surfaces of revolution (periphery) of roller is closely contacted for this cloth with throughput direction.In addition, because roller 50a, 50b can move along support frame guide part 54a, 54b as guide respectively down, so, even in moving, also can make the surfaces of revolution (periphery) of roller be maintained the state of subtend vertically for sewn object.Therefore, the surfaces of revolution of roller (periphery) can be kept carrying capacity equably for sewn object closely contact reliably.Thus, because can keep the contact pressure of the width of making thing that is transferred equably, so, can eliminate the deviation of carrying capacity.Therefore, can carry sewn object as the crow flies, obtain desirable sewing quality.
In addition, 2 rollers connect the easy structure that forms by utilization at the linkage that mutual substantial middle portion has fulcrum, not only can suppress cost, can also obtain above-mentioned effect.In addition, since make the formation of roller knee-action be by support frame 52a and 52b, carriage pallet 53a and 53b, support frame guide part 54a and 54b, jut 55a and 55b simple like this constitute form, so, even any one breakage etc. in these structures, also can simply repair by only changing these parts, therefore, can easily carry out upkeep operation.
In addition, following roller 50 also can by along guiding parts separately a plurality of rollers of independent knee-action constitute.Like this, then can be according to the thick variation of cloth of the Y direction of sewn object, with roughly uniformly pressure apply and carry action.Thus, can prevent the deviation of the cloth feed amount of Y direction.At this moment, described a plurality of roller also can always be pushed to the sewn object side by elastomer.Like this, the surfaces of revolution of upper roller 40 and following roller 50 is often closely contacted with sewn object, can apply carrying capacity reliably.In addition, under this situation, following roller 50 also can be arranged on direction of principal axis more a plurality of rollers are set.
In addition, 2 following roller 50a, 50b preferably have the roller of same diameter as shown in this embodiment.Like this, can carry sewn object with the conveying capacity that the left and right sides is identical to the pressure of sewn object even action.
In addition, though the following moving direction (glide direction) of roller 50 is preferably parallel with Z-direction, promptly, on the direction that staggers a little, also can be suitable for all vertical direction of direction of principal axis of cloth feeding direction and this time roller 50.
In addition, in the present embodiment, though upper roller 40 constitutes the driving wheel of carrying action,, also can be by roller 50 is as driving wheel down, the formation rotation drives.
In addition, in the present embodiment, be provided with a upper roller 40 and 2 following roller 50a, 50b, but, be not limited thereto, for example, also can be with respect to a following roller 50,2 even a plurality of upper roller 40 are set, can also constitute 2 even a plurality of upper roller 40 and 2 even a plurality of structure of roller 50 down.
In addition, two roller 50a, 50b are constituted the structure that connects by connecting rod body 58, but, be not limited thereto, for example, also can be on support frame 52a, 52b both sides mutually face-to-face configuration along the tooth bar of above-below direction the pinion with the tooth engagement of both sides' tooth bar is set between it, can also be provided with 2 roller 50a, 50b mutually in the other direction on only mobile phase with other mechanisms of displacement.
