Described three stepper motors 18,32,35 all are contained in one and surround in the housing (not illustrating in the drawings) of substrate 3.
The control device 38 that briefly shows in Fig. 1 is connected with last feeding adjusting device 34 signals with two following feeding adjusting devices 30,31.Control device 38 has a storage device 39, this memory device stores and pending making the relevant data of sequence and distribute to the adjusting data that these make sequence data need described adjusting data to activate stepper motor 18,32,35 when sequence is made in execution.
Utilize the possibility of the feeding length of adjusting device 30,31 and 34 independent regulation feeders 15 to 17 that the possibility of regulating is provided, comprise following main adjusting possibility:
At first, can change the feeding length of all three feeders 15 to 17 synchronously with one another in the mode that equates, thereby make all three feeders 15 to 17 move to the second public feeding length from the first public feeding length.Like this, in this case, can change the whole feeding length of Sewing machines 1 and the length that therefore changes stitching.
The second, can change the feeding path of described two following feeders 16,17 simultaneously, wherein, the feeding length of last feeder or remain unchanged perhaps changes one and is different from the amount that the feeding length of feeder 16,17 down changes.When carrying out feed distance, the change of the difference in the feeding path of feeder 16,17 and 15 processes of last feeder under this adjusting causes.This be adjusted in the differentiability that hereinafter will be called as the feeding of Sewing machines 1 (differentiability, differentiability) or the change of folding feed value.This differentiability makes and can be changed with respect to the bottom fabric by feeder 16,17 feedings down by the folding of the top fabric of last feeder 15 feedings.
The 3rd, can only change two following feeders 16,17 feeding length relative to each other, make it possible in the feeding process, change the wrinkling of bottom fabric thus, described wrinkling by descending feeder 16,17 to cause.This adjustable fabric feeding property of Sewing machines 1 is called as the change of difference (differential) or wrinkling feed value hereinafter.
Described three kinds of general adjusting possibilities, the degree that promptly " feeding length change ", " differentiability " and " difference " also can overlapped any hope.
In first illustrative methods of operation Sewing machines 1, set first feed value at first by side by side activate all three stepper motors 18,32,35 via control device 38, to be used for by means of feeder 15 to 17 moving fabrics.Subsequently, as long as set first stitch length of this first feed value-promptly, then make fabric.Subsequently, set second feed value, to be used for by means of feeder 15 to 17 moving fabrics by side by side activating stepper motor 18,32,35.Then, utilize second feed value obtain to make fabric, this second feed value may for example be higher than first feed value, and therefore the line linear slit that obtains has the big stitch length than before.
This controlled change to feed value can for example depend on by photoelectric sensor of the other sensor of Sewing machines 1-for example or the detected signal value of contact detector to be undertaken, described sensor is used to detect the end of fabric, before arriving the linear slit end, only need more slightly stitching at this place, end, thereby guaranteed-end at definite position that the length of guaranteeing the stitching that this is last simultaneously is the length of last stitching no better than by correspondingly regulating stitch length-last stitching.Owing to the outward appearance reason, stitch length is not both undesirable.Equally, when making the turning linear slit, in corner region, no longer need to reduce stitch length.
By means of control device 38, the tension force of line also automatically is adjusted to the stitch length that is suitable for determining.For this reason, control device 38 activates the electronics stringing device of Sewing machines 1, thereby particularly increases the tension force of line when stitch length increases.
The another kind of operation Sewing machines 1 substitutes or additional method is to utilize differentiability.At first, set the first folding feed value, being used for by means of feeder 15 to 17 moving fabrics, wherein, for example the fabric feed value that is provided by feeder 16,17 down is provided the fabric feed value that is provided by last feeder 15.Subsequently, utilize this first folding feed value to make fabric.Subsequently, the stepper motor 35 by regulating feeder 15 or set the second folding feed value by the stepper motor 18,32 of side by side regulating two following feeders 16,17, this second folding feed value is different from the first folding feed value.This adjusting can for example make, when setting the second folding feed value, before the feeding diversity ratio between last feeder 15 and two the following feeders 16,17 greatly, its result makes and folds with comparing more before at subsequently the fabric quilt of making in the process.The vision that this effect can be used for obtaining to wish is made the different folding behavior of effect or compensation fabric, for example when making the linear slit with direction variation in the fabric with preferred frictional direction.
Can utilize difference by the another kind of method of operating that Sewing machines 1 is carried out as substituting or replenishing of aforesaid operations method.At first, set the first wrinkling feed value, being used for by means of two following feeder 16,17 moving fabrics, wherein, for example the fabric feed value that is provided by first time feeder 16 is different from the fabric feed value of second time feeder 17.When setting the first wrinkling feed value, the feeding that is provided by first time feeder 16 is provided especially slightly in the feeding that is provided by second time feeder 17.Utilize this first wrinkling feed value to make fabric then.Subsequently, set the second wrinkling feed value by correspondingly activating one of two stepper motors 18,32 for example descend feeder 16,17, this second wrinkling feed value is different from the first wrinkling feed value.Adjusting can for example make between twice feeders 16,17 feeding difference now than before big so that by means of two more wrinkling fabrics of following feeders 16,17 acquisitions.Subsequently, utilize the second wrinkling feed value to make fabric.Equally, this third method of operating can be used for realizing that special vision makes the change that fabric property in the process is made in effect or compensation, particularly when making when having making that direction changes.
Can comprise the change of the degreeof tortuosity of change that the material of change, the fabric of the woven type of fabric is for example formed or warp and parallel by the change that changes the fabric parameter that differentiability or difference compensates.
When carrying out sewing program or making sequence, can automatically carry out by control device the actuating of stepper motor 18,32,35.Alternatively or as a supplement, this actuating can directly be undertaken by operating personnel, for example via foot-operated switch or moving lever of knee or button, thereby make operating personnel in the process of making, stitch length, differentiability or difference to be changed over any desired degree.The direct actuating of this class makes operating personnel can make fast especially and revises, usually needs so to cut out tolerance with compensation when inserting sleeve.
Especially, the change of making behavior can be compensated, and these change by causing at the warp of fabric and the angle change of making direction between the weft direction.For example when making crooked linear slit, this class compensation may be carried out in the mode that can regulate continuously.
Perhaps, replace to use external sensor, feed value also can be dependent on inner parameter and changes, for example the stitch or the linear slit path of being made.
