Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic pattern sewing machine capable of automatically selecting a pattern and a continuous pattern sewing length.

[0002]

2. Description of the Related Art A conventional sewing machine with an embroidery function having a storage device for pattern data, etc. has a large number of patterns due to the technical development capability of the sewing machine and the increase in the storage capacity of related computers. Is also increasing.

[0003]

By the way, since the number of selection switches is increased due to the increase in the number of patterns, the selection switches are provided only on the outer surface of the sewing machine. Therefore, when the user selects a pattern, It is troublesome to select many operation switches such as whether to make a pattern, which to combine with which, the pattern fits well in the seam allowance of the cloth, and the troublesome operation image is too strong to use easily I have an impression. In addition, there is a very troublesome aspect in that it is necessary to sew whether or not the selected pattern fits in exactly the required sewing length of the cloth.

[0004]

Therefore, as a result of intensive studies, the inventor of the present invention has found that the sewing machine replaces the user to select a pattern,
By designing various patterns and combinations, and then selecting only, the user simply decided the pattern menu that was sequentially issued. With automatic pattern sewing, the sewing machine automatically selects sewing patterns including combination patterns, so you can easily select patterns and realize sewing that matches the sewing length. There is no need to set it according to the number of patterns, and there is a big feature that a large number of types of pattern sewing can be done with few operation switches, and it is possible to make the design neat even with a relatively small sewing machine even though it is multi-pattern sewing. That is, the above-mentioned problems have been solved and the object thereof has been achieved.

[Table 1]

Next, by pressing the automatic pattern sewing switch,
When the arbitrary length stitch switch 10d for selecting the desired arbitrary sewing length is pressed in S2-2, S5 is pressed.
Then, the operation of the automatic pattern sewing selection timer 8a and the selection counter 8d is started, and counting corresponding to the sewing length previously stored in the automatic pattern sewing length display data storage means 12 'is performed. Then, the display of the length corresponding to the count is read one after another, and the read S is displayed on the liquid crystal display 5b.
5'is displayed as the extended display of the sewing length, and at this time, the next operation instruction necessary for selecting the sewing length of the automatic pattern is the automatic pattern sewing length display data storage means 12 in S6. ', And displayed on the liquid crystal display 5b as an instruction to re-press the arbitrary length stitch switch 10d. The displays of S5' and S6 are shown as follows, for example. (Provision display of sewing length-Operation instruction of × part and sewing length selection switch (see Table 2))

[Table 2]

When the desired pattern or sewing length appears in the X mark in the above display example, in accordance with the operation instruction of S4 or S6,
When the selection switch is pressed again in S8, the selection counter 8b, 8c or 8d is stopped in S9 to finish the selection of the desired pattern type or sewing length, and the second central processing unit In S9 ', it is determined whether or not the selection end state is an arbitrary length stitch, and if this is an arbitrary length stitch, the second central processing unit 9 determines the number of stitches of the basic pattern selected in S11. The number of stitches is calculated according to the number of stitches of which this stitch fits within the selected sewing length, and the stitch count is set in the counters 8b, 8c, 8d of the automatic stitch stitching stitch number setting counting means 13 using this stitch count. At the same time, the selected pattern and the sewing length selected in S13 are displayed on the liquid crystal display 5b as the desired automatic pattern sewing display, for example, as follows. (Display example when the sewing length is 15 cm and the pattern below is selected (see Table 3))

[Table 3]

In this case, when the selection switch for either the pattern or the sewing length is not pressed again in S8, the display is as follows, for example, and the selection switch is pressed again in S8. The cross mark indicates the extended display. (Example of display when the pattern selection switch is pressed again without pressing the sewing length selection switch again (see Table 4))

[Table 4] (Display example when the sewing length selection switch is pressed again without pressing the pattern selection switch again (see Table 5))

[Table 5]

Further, when the automatic pattern stitching selection means 10 is pushed to push the free length stitch switch 10c for selecting the free stitching length, the timer 8a is pushed at S7.
Then, the operation of the counter 8d is started, and the second central processing unit 9 preferentially sets the count value to freely correspond to the sewing length, and then the selection end state is set in S10, and S
When it is determined in 9'that these selection end states indicate free-length stitching, the counters 8b, 8 of the automatic pattern stitching stitch number setting counting means 13 for the selected pattern are determined in S12.
c and 8d are set to release the number of stitches, and the selected pattern and the free sewing length selected in S13 are displayed on the liquid crystal display 5b as the desired automatic pattern sewing display, for example, as follows. (Free stitching length, display example when selecting the pattern below (see Table 6))

[Table 6]

In this case, when the pattern selection switch is not pressed again in S8, for example, as shown below, S8
Wait for the selection switch to be pressed again. The cross mark indicates the extended display. (Display example when the sewing length is freely selected without pressing the pattern selection switch again (see Table 7))

[Table 7]

When all the selections are completed by the above operation, the second central processing unit 9 causes the counter 8b,
Corresponding to the count values of 8c and 8d, the pattern data as set from the automatic pattern sewing basic pattern generation information storage means 11 is read, and the sewing amplitude of the selected pattern in S14, the feed, and the needle driving operation state are set. , When the controller (not shown) is stepped on here, the sewing machine executes automatic pattern stitching. With the above settings, with the sewing of any length, the sewing machine automatically operates by sewing up to the selected sewing length. When the controller is released, the sewing is not performed even if the controller is stepped on. On the other hand, in the free length sewing, the sewing is performed while the controller is stepped, and the sewing is stopped when the controller is released.

If it is desired to change the type of pattern and the sewing length, it is sufficient to return to S2 and repeatedly press the selection switch to perform the same operation as described above, for example, the single pattern stitch switch 10a or the combination pattern stitch switch 10
As an example of the selection end when b and the arbitrary length stitch switch 10d are repeatedly pressed and the same operation as described above is performed, the display of S13 is changed as follows, and another automatic pattern sewing state is set. (L = 25 cm, display example when single pattern is selected (see Table 8))

[Table 8] (L = 25 cm, display example when selecting a combination pattern (see Table 9))

[Table 9]

Here, with respect to the sewing pattern and the sewing length, the automatic pattern sewing basic pattern generation information storage means 11 is provided.
Then, the types that can be changed are determined by pre-storing several types in the automatic pattern sewing pattern display data storage means 12 and the automatic pattern sewing length display data storage means 12 '.

Further, depending on the relation between the selected pattern and the sewing length of the cloth, if there is a vacant space at the end of the sewing as it is, for example, as follows, Example of stitches that leave a gap (see Table 10))

[Table 10] When the second central processing unit 9 calculates the number of stitches of the selected pattern that fits within the selected sewing length as described above, it also calculates the number of stitches of the straight stitches in the vacant portion where the selected sewing length remains. , So that half of the number of stitches of the straight stitch enters the sewing start and end of the automatic pattern stitching by the selected pattern, the number of stitches of the automatic pattern stitching by the selected pattern of the automatic stitch number setting counter 13 is counted. A command to set the number of stitches for linear stitching before and after the value, and to alternately read the automatic pattern stitching according to the selected pattern and the stitching data for each half of the linear stitch from the automatic pattern stitching basic pattern generation information storage means 11 according to this setting. By carrying out the sewing, it is possible to exactly fit the selected pattern in the sewing length as follows. (Example of sewing in which the selected pattern does not deviate to the front and back of the cloth for any sewing length (see Table 11))

[Table 11]

Since the number of stitches is set appropriately according to the sewing length in this way, the sewing machine counts the number of stitches even if the sewing is performed all at once, and when the number of stitches reaches the set number of stitches, the sewing machine stops. Since the sewing is not performed, the sewing does not form a semi-pattern that protrudes from the predetermined length, and the pattern sewing that automatically achieves the correct sewing length is performed.

In this embodiment, the control system is divided into the normal pattern sewing control section A and the automatic pattern sewing control section B.
These control systems may be configured such that all of the automatic pattern sewing control section B is incorporated into the normal pattern sewing control section A, or a part of the automatic pattern sewing control section B is combined with the normal pattern sewing control section A. In addition, in the automatic pattern stitching control section B, the single pattern stitch switch 10a and the combination pattern stitch switch 10b of the automatic pattern stitching selection means 10 or the free length stitch switch 10c and the arbitrary length stitch switch 10d. Selection operation function, the counter 8b, 8c and 8d of the counting means 8 for automatic pattern sewing selection and counting function, or the automatic pattern sewing pattern display data storage means 12 and the automatic pattern sewing length display data storage means 1
Needless to say, it is applicable within the scope of the present invention that each of the memory functions of 2'is configured as one.

[0040]

As described above, in the automatic pattern stitching sewing machine according to the present invention, the sewing machine automatically circulates the pattern and the sewing length and continuously and successively displays them, so that the user can see them. Since it is only necessary to select the required sewing pattern and length, and the pattern automatically fits well within the desired sewing length, it is extremely useful in practice and, as in the past,
You can think about the pattern to select while holding down the selection switch, and avoid all that you don't know if the pattern will not fit within the specified sewing length and become a half pattern until you sew it. There is an advantage that it is possible to realize tailored sewing.

Further, although the sewing machine is a relatively small-sized sewing machine and is multi-pattern sewing, the number of patterns prepared in advance may be small,
You can also make it look cleaner.

Further, by doing so, a great number of sewing patterns can be provided. That is, it is not necessary to provide the automatic pattern stitching selection means 10 substantially in accordance with the number of patterns, and there is a great effect that a large number of types of pattern stitching can be performed with a small number of operation switches.

Further, the pattern and the sewing length initially selected can be changed and selected by repeatedly pressing the selection switch, and at the time of selecting these stitches, various kinds of ones are automatically fed out one after another. There is an advantage that a large number of stitches can be selected with the switch.
