Abstract

In an embroidery sewing machine, a value setting screen on a display indicates parametrical items about the movement of an embroidering frame, i.e., “sewable area” and “stand-by position”, as well as parametrical items about the sewing operation, i.e., “thread-breakage sensitivity” and “number of stitch-back stitches”. An operator enters or designates optimum values for those parametrical items by operating numerical keys and cursor moving keys on a keyboard, and registers a name to be assigned to a set of values for those parametrical items. The set of values for those parametrical items are stored in a floppy disk in relation to the registered name. By simply designating one of the registered names correspondingly to a material to be sewn, the optimum values for the parametrical items are retrieved simultaneously and set for the sewing operation.

retrieving means for retrieving, from said storing means, said value of a group corresponding to said selected name for said at least one parametrical item.

2. A sewing machine control system according to claim 1, further comprising:

transferring means for transferring said value of said group retrieved by said retrieving means to said control means.

3. A sewing machine control system according to claim 1, wherein said sewing machine includes an embroidery sewing machine capable of forming an embroidery pattern on said material mounted on an embroidering frame.

4. A sewing machine control system according to claim 3, wherein said at least one parametrical item includes at least one of a sewable area, a stand-by position, a thread-breakage sensitivity, a number of stitch-back stitches, a sewing start position, and a sewing speed.

5. A sewing machine control system according to claim 1, wherein said selecting means selects said one of said plurality of names by displaying a list of said plurality of names on said display unit and designating said one of said plurality of names on said display.

21. A control system according to claim 1, wherein a name registered by said registering means is constructed by at least one of a number, a symbol and a character, and can distinguish a corresponding group from other groups.

22. The sewing machine control system according to claim 1, wherein one group is differentiated from another group on the basis of at least one of a kind of material to be sewn and a size of an embroidery pattern to be sewn.

6. A method of controlling a sewing machine, said method comprising the steps of:

setting a value of each group for at least one parametrical item with respect to at least one of material-feeding and sewing operations;

registering a user-entered name assigned to said value of said each group for said at least one parametrical item;

storing said value of said each group for said at least one parametrical item in relation to said name thus registered;

selecting one of a plurality of names, each of said plurality of names being stored in relation to said value of a corresponding group for said at least one parametric item; and

retrieving said value of a group corresponding to said name thus selected for said at least one parametrical item.

7. A method according to claim 6, further comprising the step of:

using said value of said group thus retrieved to control said sewing machine.

8. A method according to claim 6, wherein said at least one parametrical item includes at least one of a sewable area, a stand-by position, a thread-breakage sensitivity, a number of stitch-back stitches, a sewing start position, and a sewing speed.

9. A method according to claim 6, wherein said selecting step includes displaying a list of said plurality of names on said display unit and designating said one of said plurality of names on said display.

23. The method according to claim 6, wherein one group is differentiated from another group on the basis of at least one of a kind of material to be sewn and a size of an embroidery pattern to be sewn.

10. A method of setting a sewing condition applicable to a control for a sewing machine, said method comprising the steps of:

displaying a setting screen on a display to indicate at least one parametrical item with respect to at least one of material-feeding and sewing operations;

setting a value for said at least one parametrical item;

relating said value to one of groups by assigning a user-entered name to said value; and

storing said value and said name in a storage medium.

11. A method according to claim 10, wherein said steps of displaying, setting, relating and storing are repeated to store said value and name of each of said groups in said storage medium.

12. A method according to claim 10, further comprising the steps of:

adding a blank portion on said display if setting of said value is complete; and

entering said name to be assigned to said value into said blank portion.

24. The method according to claim 10, wherein one group is differentiated from another group on the basis of at least one of a kind of material to be sewn and a size of an embroidery pattern to be sewn.

13. A method of handling a sewing condition applicable to a sewing machine having a storage medium in which values of a plurality of groups for at least one parametrical item with respect to at least one of material-feeding and sewing operations are stored in relation to user-entered registered names, each of said registered names corresponding to each of said plurality of groups, said method comprising the steps of:

indicating a list of said registered names on a display;

selecting one registered name from said list;

retrieving, from said storage medium, a value of a group corresponding to said registered name thus selected; and

controlling said sewing machine using said value of said group thus retrieved.
