Sewing stabilizing device and sewing stabilizing method

The present invention relates to a sewing stabilization device and a sewing stabilization method, in particular to a sewing stabilization device and a sewing stabilization method for detecting the edge of cloth and maintaining the stability of the sewing process.

Sewing refers to a crafting technique that stitches objects together with needles and yarns. This technique first appeared in prehistoric times and played an important role in the future of human history. During these thousands of years, almost all sewing work was done with both hands. In recent centuries, with the invention of semi-automatic sewing machines and electric sewing machines, and the popularization of programmable computerized equipment, textiles have begun to be mass-produced and spread all over the world. At present, when sewing machines on the market respond to long-distance sewing needs, it is usually necessary for on-site operators to manually adjust the position and direction of the fabric during the process of sewing the fabric. In this way, it is possible to ensure that the sewing result between the fabric and other fabrics is correct during the process of sewing the fabric.

However, the aforementioned technical means that must rely on on-site operators to manually adjust the position and direction of the fabric are not only likely to be limited by the experience and perception of on-site operators, resulting in poor overall production efficiency and stability of sewing quality. It is not high, and it is easy to cause unnecessary trauma to on-site operators.

For this reason, how to design a sewing stabilization device and sewing stabilization method, especially to solve the technical problems of poor production efficiency, low sewing quality stability and safety concerns of operators in the prior art, is the research of the inventor of this case. important topic.

One purpose of the present invention is to provide a sewing stabilization device that can automatically adjust the position and direction of the fabric during the process of sewing the fabric, avoiding the technical problems of the prior art that are limited by the experience and perception ability of the on-site operator, and achieving improvement The purpose of production efficiency, sewing quality stability and improving operation safety.

In order to achieve the foregoing objective, the sewing stabilization device proposed by the present invention provides a sewing unit to sew the cloth moving in a first direction. The sewing stabilization device includes an edge detection module and an edge correction module. Wherein, the edge detection module straddles the edge of the cloth, and outputs the detection spectrum along the second direction perpendicular to the first direction. The edge detection module generates the first correction signal according to the response of the detection spectrum, or according to the unification of the detection spectrum. In response, a second calibration signal is generated. The edge correction module receives the first correction signal or the second correction signal, and moves the edge of the fabric according to the first correction signal to approach the sewing unit along a third direction perpendicular to the first direction and perpendicular to the second direction, or according to the second The correction signal moves the edge of the fabric away from the sewing unit in the third direction. Wherein, the edge detection module continuously generates one of the first calibration signal and the second calibration signal.

Furthermore, in the sewing stabilization device, the detection spectrum includes at least one of visible light, infrared, ultrasonic, sonar, radio frequency identification, near field communication, and laser.

Furthermore, in the sewing stabilization device, the edge detection module includes a spectrum output terminal and a spectrum receiving terminal. The spectrum output terminal and the spectrum receiving terminal are respectively arranged outside two opposite sides of the cloth along the second direction, and the spectrum output terminal The detection spectrum is output, and the spectrum receiving terminal judges whether the detection spectrum responds according to whether the detection spectrum output by the spectrum output terminal is received.

Furthermore, in the sewing stabilization device, there are a plurality of edge detection modules, and a plurality of edge detection modules are arranged side by side along the first direction.

Furthermore, in the sewing stabilization device, the edge correction module keeps the edge of the cloth and the sewing unit at a fixed distance.

Furthermore, the sewing stabilization device further includes a control unit coupled to the edge detection module, the edge correction module, and the sewing unit. Wherein, when the edge detection module generates the first correction signal, the control unit controls the edge correction module to move the edge of the cloth to approach the sewing unit along the third direction. When the edge detection module generates the second correction signal, the control unit controls the edge correction module to move the edge of the cloth away from the sewing unit along the third direction.

Another object of the present invention is to provide a sewing stabilization method that can automatically adjust the position and direction of the fabric during the process of sewing the fabric, which can avoid the technical problems that the prior art is limited to the experience and perception ability of the on-site operator, and achieve The purpose of improving production efficiency, sewing quality stability and improving operation safety.

In order to achieve the aforementioned another object, the sewing stabilization method proposed by the present invention provides a sewing unit to sew the cloth moving in a first direction. The sewing stabilization method includes the following steps: outputting detection in a second direction perpendicular to the first direction Frequency spectrum, and generate the first correction signal according to the response of the detection spectrum, or generate the second correction signal according to the unresponsiveness of the detection spectrum. Move the edge of the fabric according to the first correction signal to approach the sewing unit along a third direction perpendicular to the first direction and perpendicular to the second direction, or move the edge of the fabric to move away from the sewing unit along the third direction according to the second correction signal. Wherein, one of the first calibration signal and the second calibration signal is continuously generated.

Furthermore, in the sewing stabilization method, the detection spectrum includes at least one of visible light, infrared, ultrasonic, sonar, radio frequency identification, near field communication, and laser.

When using the sewing stabilization device and the sewing stabilization method of the present invention, the edge detection module can determine whether to generate the first correction signal or the second correction signal according to whether the edge detection module detects the response of the frequency spectrum after it is placed across the cloth. When the edge detection module confirms that the detection spectrum has responded (that is, it means that the edge detection module has received the detection spectrum, the edge of the cloth is not covered by the detection spectrum, and the edge of the cloth has deviated from the sewing area), the edge detection module generates the first correction signal, And the edge correction module moves the edge of the fabric along the third direction to approach the sewing unit according to the first correction signal (that is, the edge of the fabric that has deviated from the sewing operation area is moved to the sewing operation area, and the edge of the fabric can mask the detection spectrum). Or, when the edge detection module confirms that the detection spectrum is not responding (that is, the edge detection module does not receive the detection spectrum, the cloth covers the sewing area and has blocked the detection spectrum, but it is unknown whether the edge of the cloth has deviated from the sewing area), The edge detection module generates a second correction signal, and the edge correction module moves the edge of the fabric along the third direction away from the sewing unit according to the second correction signal (that is, it means that the edge of the fabric is moved to the sewing area, and the edge of the fabric is not Mask detection spectrum). For this reason, the edge correction module keeps the edge of the cloth and the sewing unit at a fixed distance. Furthermore, during the period when the edge detection module generates the first calibration signal or the second calibration signal, specific conditions (such as a specific time, a specific period, or a specific frequency, etc.) can be matched to make the edge correction module's effect on the edge of the cloth The control has the technical effect of more precise alignment or more diversified control.

For this reason, the sewing stabilization device and the sewing stabilization method of the present invention can automatically adjust the position and direction of the fabric during the process of sewing the fabric, which can avoid the technical problem that the prior art is limited by the experience and perception ability of the on-site operator.
