技术领域technical field
本发明属于缝纫技术领域，涉及一种缝料自动感应系统及方法。The invention belongs to the technical field of sewing, and relates to a sewing material automatic sensing system and method.
背景技术Background technique
目前电脑缝纫机对不同缝料的感应识别能力很有限，由于当感应灵敏度设置较高时，外界环境诸如光线、灰尘、油污等因素的干扰都容易被接收器识别到而造成机器误动作，因此其感应灵敏度一般设置为能适应一般中厚料的状态，其存在的问题是：当用户欲缝纫非常薄透的特别是带孔的网纱料时，因该类缝料对红外线遮挡作用十分弱，使发射器发出的红外线大部分穿透缝料，感应系统基本无法识别到有无缝料存在，导致机器不正常运转，甚至造成缝料损坏；此时需将调整系统感应灵敏度以适应当前缝料方可正常缝纫，但因不同缝料所需的灵敏度不同，调节改参数需根据当前缝纫的综合状况判断，非专业人士很难准备判断和调节好该参数，调节麻烦且工作效率低下。At present, the ability of computerized sewing machines to recognize different sewing materials is very limited. When the sensing sensitivity is set high, interference from external factors such as light, dust, oil and other factors are easily recognized by the receiver and cause machine malfunctions. Therefore, its The sensing sensitivity is generally set to be able to adapt to the state of general medium-thick materials. The existing problem is: when the user wants to sew very thin mesh materials, especially mesh materials with holes, because such sewing materials have a very weak blocking effect on infrared rays, Most of the infrared rays emitted by the transmitter penetrate through the sewing material, and the sensing system basically cannot recognize the existence of seamless material, resulting in abnormal operation of the machine and even damage to the sewing material; at this time, the sensing sensitivity of the system needs to be adjusted to suit the current sewing material It can be used for normal sewing, but because of the different sensitivities required for different sewing materials, the adjustment and modification parameters should be judged according to the current sewing situation.

具体实施方式detailed description
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
如图1所示，本缝料自动感应系统，包括：As shown in Figure 1, the sewing material automatic sensing system includes:
一组红外线传感器，为自动送料感应器，用来感应是否有缝料3进入，包括安装在缝纫机机头1上的红外线发射器2和安装在缝台5上的红外线接收器4。当然根据需要也可以增加红外线传感器，比如增加自动剪线红外线传感器，用来感应缝料3是否缝纫结束需剪线，也可以增加完成其他功能的红外线传感器。本实施例中的红外线传感器也可以由可见光传感器来替代，当然也可以为其他只要对光强度变化能够检测辨别的感应器；A group of infrared sensors are automatic feeding sensors for sensing whether sewing material 3 enters, including an infrared emitter 2 installed on the sewing machine head 1 and an infrared receiver 4 installed on the sewing table 5 . Of course, infrared sensors can also be added according to needs, such as adding an automatic thread trimmer infrared sensor to sense whether the sewing material 3 needs to be trimmed after sewing, or an infrared sensor for completing other functions can also be added. The infrared sensor in this embodiment can also be replaced by a visible light sensor, and of course it can also be other sensors that can detect and distinguish changes in light intensity;
人机交换界面7，嵌设在缝纫机机身上，包括用来显示信息的液晶显示屏9和面料感应识别开关8；人机交换界面7包括但不限于嵌设在缝纫机机身上，也可以直接安装在缝纫机上或者外设其通过线路与控制器6连接；The man-machine exchange interface 7 is embedded on the sewing machine body, including a liquid crystal display 9 for displaying information and a fabric induction identification switch 8; the man-machine exchange interface 7 includes but is not limited to being embedded on the sewing machine body, and can also be It is directly installed on the sewing machine or the peripheral device is connected to the controller 6 through a line;
控制器6，为缝纫机电控一部分，也可以单独设置且与缝纫机电控连接。The controller 6 is a part of the electric control of the sewing machine, and can also be set separately and connected with the electric control of the sewing machine.
当需要更换缝料3时，由于不同类型缝料3的厚薄、纱型和颜色等特性的不同，特别是厚薄度这一要素相差较大的话，其对红外线的遮挡能力影响很大，因此不同类型的缝料3置于缝台55上缝纫时，红外线接收器4接收到的红外光强度也会不同，这样控制器6不调整感应光线强度灵敏度的话其控制准确性将不高。因此在更换特性差别较大特别是厚薄度差别较大时，需启动缝料识别系统判定是否要对控制器6的光感应灵敏度进行调节。When it is necessary to replace the sewing material 3, due to the different characteristics of different types of sewing materials 3 such as thickness, yarn type and color, especially if the factor of thickness is greatly different, it has a great influence on the shielding ability of infrared rays, so different When the type of sewing material 3 is placed on the sewing table 55 for sewing, the intensity of infrared light received by the infrared receiver 4 will also be different, so the control accuracy will not be high if the controller 6 does not adjust the sensitivity of the sensing light intensity. Therefore, when the difference in replacement characteristics is large, especially the difference in thickness, it is necessary to start the sewing material identification system to determine whether to adjust the light sensitivity of the controller 6 .
如图2所示，缝料识别系统的工作原理如下：As shown in Figure 2, the working principle of the sewing material identification system is as follows:
S1、切换缝料3，启动缝料识别系统：切换缝料3时，当切换前后的缝料3厚度相差较大时，即主要是指切换前后的缝料3对光线遮挡效果变化较大时，启动缝料识别系统；S1. Switch the sewing material 3 and start the sewing material identification system: when switching the sewing material 3, when the thickness of the sewing material 3 before and after switching is quite different, that is, it mainly refers to when the light blocking effect of the sewing material 3 before and after switching changes greatly , start the sewing material identification system;
S2、采集未放缝料3时感应器反馈电压值a：启动面料感应识别开关8，自动送料红外线传感器工作，采集未放入缝料3时的光信息并转化成电压值a反馈给控制器6，控制器6将电压值a通过人机交换界面7显示出来；S2. Collect the sensor feedback voltage value a when the sewing material 3 is not placed: start the fabric induction recognition switch 8, automatically feed the infrared sensor to work, collect the light information when the sewing material 3 is not placed and convert it into a voltage value a and feed it back to the controller 6. The controller 6 displays the voltage value a through the man-machine exchange interface 7;
S3、采集放置缝料3时感应器反馈电压值b：待人机交换界面7上显示进入有缝料数据读取时，放入缝料3，自动送料红外传感器采集放入缝料3时的光信息并转化成电压值b反馈给控制器6；S3. Collect and place the sensor feedback voltage value b when the sewing material 3 is placed: When the man-machine exchange interface 7 shows that there is sewing material data reading, put in the sewing material 3, and the automatic feeding infrared sensor collects the light when the sewing material 3 is put in The information is converted into a voltage value b and fed back to the controller 6;
S4、控制器根据反馈的电压值a和电压值b之间差值调节相应的感应灵敏度：控制器6根据电压值a和电压值b之间差值大小来调节自身的光感应灵敏度，并将电压值b通过人机交换界面7显示出来，当电压值a和电压值b差值较小时，即所测缝料3为光线遮挡能力较差，一般为薄料缝料，控制器6调高自身的光感应灵敏度，这样能够准确检测出是否有缝料3；反之，即所测缝料3对光线遮挡能力较强，判定为中厚度缝料，则调低自身的光感应灵敏度。通过采集有、无缝料3遮挡前后的光信息，即电压值a和电压值b之间的差值来判定该缝料3对光线的遮挡能力大小，从而判定该缝料3是哪种类型的缝料，控制器6调节自身相应的光感应灵敏度来参与工作；操作非常方便，且自动操作，效率高，同时精确量化进行采集并判断从而提高其控制准确性；S4, the controller adjusts the corresponding sensing sensitivity according to the difference between the feedback voltage value a and the voltage value b: the controller 6 adjusts its own light sensing sensitivity according to the difference between the voltage value a and the voltage value b, and The voltage value b is displayed through the man-machine exchange interface 7. When the difference between the voltage value a and the voltage value b is small, that is, the measured sewing material 3 has a poor light shielding ability, and is generally a thin sewing material. Its own light sensing sensitivity can accurately detect whether there is sewing material 3; on the contrary, that is, the measured sewing material 3 has a strong ability to block light, and it is judged to be a medium-thickness sewing material, then lower its own light sensing sensitivity. By collecting the light information before and after being blocked by the seamless material 3, that is, the difference between the voltage value a and the voltage value b, the ability of the sewing material 3 to block light is determined, so as to determine the type of the sewing material 3 The sewing material, the controller 6 adjusts its own corresponding light sensitivity to participate in the work; the operation is very convenient, and the operation is automatic, the efficiency is high, and at the same time, the accurate quantification is collected and judged to improve the control accuracy;
S5、关闭缝料识别系统，同时启动自动缝纫系统：关闭启动面料感应识别开关8以结束缝料识别系统工作，然后自动进入自动缝纫系统。S5. Turn off the sewing material identification system and start the automatic sewing system at the same time: close and start the fabric induction identification switch 8 to end the work of the sewing material identification system, and then automatically enter the automatic sewing system.
