Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention eliminates failure due to the thickness of a cloth in embroidering by a sewing machine with an embroidery function, and embroiders a cloth of any thickness. The present invention relates to an embroidery sewing machine with a data correction function having the function of 2. Description of the Related Art In a conventional embroidery sewing machine, the amount of shrinkage of the cloth varies depending on the type and thickness of the cloth. When embroidering is performed using the same pattern data, particularly in the case of a cloth that is easily shrunk, the X and Y directions are relatively moved in each case, and the sewing is often shifted. For this reason, nonwoven fabrics and the like have been applied to the back or adhered for the purpose of preventing it. [0003] The present invention aims to provide an embroidery that can be stably and neatly produced without causing sewing displacement, regardless of the type and thickness of the cloth, and without reinforcing by placing a nonwoven fabric on the back. . [0004] In order to solve the above-mentioned problems, the inventor of the present invention has intensively studied and, as a result, embroidered the ideas on a sewing machine with an embroidery function having an XY drive unit. A storage unit for storing pattern data, a pattern selection unit for selecting the embroidery pattern data, a cloth thickness selection unit for selecting the cloth thickness, and a correction data storage unit for correcting the embroidery pattern data by the cloth thickness selection unit; The object is achieved by providing a correction data storage unit for correcting pattern data with correction data and a calculation unit for converting embroidery pattern data into corrected embroidery data with correction data. An embodiment of the present invention will be described below with reference to FIGS. Reference numeral A denotes a sewing machine with an embroidery function, which refers to an embroidery sewing machine capable of performing only embroidery sewing and a composite sewing machine capable of performing normal sewing and embroidery sewing.
The sewing machine A with an embroidery function incorporates a computer program in advance, and is configured to perform various embroidery operations by a control device including a central processing unit (CPU). The sewing machine A with the embroidery function is provided with an XY drive unit 1 as shown in FIG. 1, and the XY drive unit 1 is controlled by an XY motor control circuit.
The motor and the Y motor are driven, and the carriage guide 1a
A Y carriage body 1b that moves in the X direction and follows the carriage guide 1a in the X direction, and is also movable in the Y direction by a Y motor. That is, the Y carriage body 1b is provided so as to be movable as appropriate in the XY directions. An embroidery frame 4 is attached to the Y carriage body 1b via an attachment 2. FIG. 2 shows a conventional method.
Shows a state in which the embroidery is attached by the outer frame 4 and the inner frame 5. Since the outer frame 4 and the inner frame 5 are stretched without slack, the embroidery is performed with the cloth stretched. . In this manner, when the embroidered cloth 3 is removed from the frame, the embroidery cloth 3 returns to its original state, causing a pattern collapse. FIG. 3 schematically shows the seam at this time. The stitches before the embroidered cloth 3 is removed from the embroidery outer frame 4 and the inner frame 5 are a, b, c, d.
(Solid line), and when it is removed from the embroidery outer frame 4, the stretched cloth returns to the natural state, and the stitches are ef, g, and h (dashed lines), and the stitches are in a contracted state. Reference numeral 6 denotes an embroidery pattern data card, which is inserted into an input means of a main body 7 provided on a side of the sewing machine A with an embroidery function so as to be inserted.
By inserting the card, pressing the start button 8 and pressing a desired selection key, the card is temporarily stored in the selected pattern storage means selected from the selected pattern data. Reference numerals 9a, 9b and 9c are cloth thickness selection keys, which correspond to correction data stored in an internal correction data storage means. Thus, when the cloth thickness is selected by the cloth thickness selection key, the correction data is read out to the pattern data, and the correction data is calculated by the correction data calculating means for performing the calculation processing using the data. In the calculated data, a correction value corresponding to the cloth shrinkage is added or subtracted in the X and Y directions, respectively, and the amount of movement in the X and Y directions becomes large or small. 4, the cloth 7 is a seam i, j, kl (dashed line) in a state where the cloth 7 is stretched by the embroidery outer frame 4 and the inner frame 5;
When the embroidery frame is removed, the seams are indicated by solid lines a, b, c, and d. According to the present invention, in a sewing machine with an embroidery function having an XY drive section 1, a storage section for storing embroidery pattern data, a pattern selecting means for selecting the embroidery pattern data, and a cloth A data correction function comprising a cloth thickness selecting means for selecting the thickness of the embroidery pattern, a data storage unit for correcting the embroidery pattern data by the cloth thickness selecting means, and a calculation unit for converting the embroidery pattern data into the corrected embroidery pattern data by the correction data. By using a sewing machine with a stitch, firstly, embroidery can be performed neatly and reliably regardless of the thickness of the cloth.
Secondly, no effort is required without sticking a non-woven cloth or the like on the back. To describe these effects in detail, by storing the correction data in the storage unit, the embroidery pattern data can be used without creating new embroidery pattern data. Not only the thickness of the cloth, but also the type and quality of the cloth, so even beginners and those who are not familiar with sewing machines can make mistakes,
Embroidery can be performed with certainty, and opportunities for using the sewing machine will increase. When embroidering is performed in the conventional manner, the resulting embroidery may have a seam that is too fine, coarse, or large or small compared to the standard one. It was mixed depending on the thickness and the like. This has the advantage that all fabrics of all types are made the same, regardless of the skill level of the handler. Further, even though the data correction function is provided, the configuration is made up of a selection means for selecting the thickness of the cloth, a storage unit for storing the data, and an arithmetic unit for converting the embroidery pattern data by using these means. There are advantages that can be provided.
