New description: [New technical field] [0001] This creation is about a sewing equipment application technology, especially regarding a sewing machine sewing multi-point positioning Setting device, which can be applied to a sewing device, for the user to conveniently and quickly set the value of a set of sewing position points required for the sewing device in actual operation, so that the motor is used in the sewing device In actual operation, the sewing needle can be precisely controlled to move to the desired positioning point of each sewing seam.

[Prior Art] [0002] A sewing machine is a machine that can be used to make textiles, and its main function is to automatically sew the textile threads into one. At present, the mechanism of the automated sewing apparatus usually includes a motor and a sewing needle, wherein the motor is used to drive the sewing needle to perform a sewing process of reciprocating up and down, thereby sewing the thread into the fabric of the textile. In actual operation, the sewing needle of the general standard sewing machine basically includes the following several sewing points when performing the sewing operation of the upper and lower reciprocating cycles: [0003] PO. Reference point position, expressed as REF, meaning For Reference [0004] P 1 . The upper stop position is shown as PUA, meaning Pos it

Ion UP A

[0005] P2. The next stop position is shown as PDA, meaning Po s i t

Ion Down A

[0006] When the sewing needle moves to these positioning points, the motor must control the sewing needle to make a momentary stop work, thereby setting the angle to stop the needle form number A0101 Page 3 / 21 pages 100 years OiJ month 02 The Japanese core is replacing the page or the drive is working or off. Since the sewing operation of the sewing needle is controlled by the rotation of the main shaft of the motor, and the rotation of the motor main shaft is the number of encoder pulses, the above positioning points correspond to one rotation of the motor main shaft respectively. An angle (hereinafter referred to as '"sewing anchor point 〃). For example, the sewing angles corresponding to the above-mentioned sewing positioning points can be respectively expressed as 〇ρΛ, 〜, etc. In terms of implementation.

REF PUA PDA, as long as we can control the motor's spindle to rotate to a position equal to the rotation position of each sewing point, the sewing needle can be moved to the desired sewing position. [0007] However, in practical applications, the current sewing machine motors usually have a wide variety of different specifications, including, for example, direct drive, underhang, back-hanging, etc.; while the type of positioning control device is Including built-in and add-on, so the positioning adjustment methods provided are also different. The positioning adjustment method of the built-in motor must first find the motor reference point, and then reassemble it with the headrest reference point; if there is a slight offset, it must be removed and re-adjusted, and the external adjustment is adjusted. The position of the sensing point of the positioning control device is offset, and once the offset of the sensing point is adjusted, the position of each sewing position must be re-adjusted. For this reason, the sewing machine often has to adjust the value of the position of the sewing position with the change of the mechanical structure after the assembly of the test machine, which is extremely inconvenient, time-consuming and labor-intensive and inefficient. [0008]

The industry therefore needs a new technology that allows the user of the sewing machine to easily and quickly reset the required number of seams in any case of changes to the motor of the sewing machine and its positioning control device. The value of the point positioning, that is, the aforementioned θ ΚΕ ρ, θ ρ Μ, 0 pDA, and the like. Form No. A0101 Page 4 of 21

Here, the encoder (E nc 〇de Γ ) 3 2 (see Fig. 3) is placed on the motor 3 ,, where the number of displacements and the resolution of the table encoder (CPR: C〇unt s Per Revolution) are It's easy to explain the example of 3 60 CPR. However, it is not necessary to make 3-6 to improve the manufacturing technology and the demand. 8 〇, 5 2 〇 'Work 〇 〇 〇 are all feasible' Please explain. As shown in Fig. 4, the sewing device sewing position setting device 100 of the present invention comprises the following modules in structure: (A) - positioning point position detecting module 11; (B) positioning position display Module 2 0 ; (C) - Positioning point position value capture module 丄 3 〇; and (D) - Positioning point position value input module 14 〇. The positioning point position detecting module 1 1 can be manually moved to any specific position by the user using the hand wheel 50 (or other equivalent technical means such as the pedal 60) by the sewing needle 20 of the sewing device i 〇. At this time, the positioning point corresponding to the sewing needle 20 at the specific position is detected, and an positioning point position signal is issued to represent the value. In theory, since the up and down movement of the sewing needle 20 will drive the spindle 3 1 of the motor 3 做 to rotate relative to each other, and each fixed positioning point corresponds to the range of the encoder pulse wave rotation angle of the spindle 31 A fixed angle value, so we can only detect the spindle of the motor 3 3 relative to the form number A0101 page 9 / 21 pages M412981 [0033] 1G0 August 02 shuttle replacement page The rotation point of a reference point can be used as the positioning angle corresponding to the sewing point. Therefore, conversely, in actual operation, as long as we can control the spindle 31 of the motor 30 to rotate to a pre-designated and set rotational displacement point (ie, the positioning angle), the motor 30 can drive the sewing needle 20 to move to Required seam positioning points. In a specific implementation, the positioning point position detecting module 110 can detect the current rotational displacement value of the main shaft 31 of the motor 30 by using various prior art techniques to thereby obtain the required sewing position. For example, a feasible technique has been disclosed in the patent publication number 5 3 7 3 2 0 of the applicant's patent for improving the sewing machine needle positioning device (1), and the patent publication number 5 5 3 2 3 7 'Improvement of sewing machine needle positioning device (2) 〃. The two patented technologies utilize an encoder and a marker (not shown in the drawings) provided on the spindle of the motor to generate intermittent interruption and photoelectric induction of light when the spindle rotates as shown in FIG. One of the series of pulse wave signals is shown; wherein each of the pulse wave signals generated by the marker is as shown in the Synchon izer Index in FIG. 3 (for simplicity, only Take the 360CP R encoder as an example) to indicate that the motor spindle rotates exactly one full turn, that is, 3 60 °; and each pulse wave period generated by the encoder is as shown in Fig. 3. Encoder (E nc 〇der ), which represents the angular displacement value of a unit, such as 1° or 0. 5°, the value can be arbitrarily specified, but in principle the smaller value can make the angular displacement value have more High resolution (Re s 1 uti on).
