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 and two lower feeding adjusting devices 30,31 are connected signal and are connected with the upper feeding adjusting device.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 adjustment possibility:
At first, can change synchronously with one another in the mode that equates the feeding length of all three feeders 15 to 17, thereby so that 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 simultaneously described two lower feeding devices 16,17 feeding path, wherein, the feeding length of upper feeding device or remain unchanged perhaps changes one and is different from the amount that lower feeding device 16,17 feeding length change.When carrying out feed distance, this adjusting causes lower feeding device 16,17 and the change of the difference in the feeding path of 15 processes of upper feeding device.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 is so that can be with respect to the bottom fabric change by lower feeding device 16,17 feedings by the folding of top fabric of upper feeding device 15 feedings.
The 3rd, can only change two lower feeding devices 16,17 feeding length relative to each other, make it possible to thus in the feeding process to change the wrinkling of bottom fabric, described wrinklingly caused by lower feeding device 16,17.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 adjustment possibilities, the degree that namely " feeding length change ", " differentiability " and " difference " also can overlapped any hope.
In the first illustrative methods of operation Sewing machines 1, set at first the first feed value 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 the first stitch length of this first feed value-namely, then make fabric.Subsequently, set the second feed value by side by side activating stepper motor 18,32,35, to be used for by means of feeder 15 to 17 moving fabrics.Then, utilize the second feed value obtain to make fabric, this second feed value may for example be higher than the first feed value, and the line linear slit that therefore obtains has the large stitch length than before.
This controlled change to feed value can for example depend on the signal value that is detected by the photoelectric sensor of the other sensor of Sewing machines 1-for example or contact detector and carry out, described sensor is for detection of the end of fabric, locate until only need slightly more stitching before arriving the linear slit end in this end, thereby guaranteed-end at definite position by correspondingly regulating stitch length-last stitching, guaranteed that simultaneously the length of the stitching that this is last is no better than the length of 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 wire tensioning 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, the fabric feed value that is provided by lower feeding device 16,17 is provided the fabric feed value that is for example provided by upper feeding device 15.Subsequently, utilize this first folding feed value to make fabric.Subsequently, the stepper motor 35 by regulating upper feeding device 15 or by side by side regulate two lower feeding devices 16,17 stepper motor 18,32 is set the second folding feed value, this second folding feed value is different from the first folding feed value.This adjusting can be for example so that, when setting the second folding feed value, before the feeding diversity ratio between upper feeding device 15 and two the lower feeding devices 16,17 greatly, its result is so that folded with comparing more tightly before at subsequently the fabric 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 lower feeding devices 16,17 moving fabrics, wherein, the fabric feed value that is for example provided by the first lower feeding device 16 is different from the fabric feed value of the second lower feeding device 17.When setting the first wrinkling feed value, the feeding that is provided by the first lower feeding device 16 is provided especially slightly in the feeding that is provided by the second lower feeding device 17.Then utilize this first wrinkling feed value to make fabric.Subsequently, set the second wrinkling feed value by correspondingly activating lower feeding device 16 for example, two stepper motors 18 of 17, one of 32, this second wrinkling feed value is different from the first wrinkling feed value.Adjusting can be for example so that the feeding difference between the two lower feeding devices 16,17 now than before large so that by means of two lower feeding devices 16, the more wrinkling fabric of 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 by the change that changes the fabric parameter that differentiability or difference compensates the change of the degreeof tortuosity of change that the material of change, the fabric of the woven type of fabric for example forms or warp and parallel.
When carrying out sewing program or making sequence, can automatically carry out by control device stepper motor 18,32,35 actuating.Alternatively or as a supplement, this actuating can directly be undertaken by operating personnel, for example via foot-operated switch or the moving lever of knee or button, thereby so that operating personnel can change over stitch length, differentiability or difference the degree of any expectation in the process of making.This class directly activates special so that operating personnel can make fast correction, 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 Angulation changes 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 stitch or the linear slit path of making.
