Detailed Description
The core of the invention is to provide a speed regulating system and a sewing machine, wherein a full reverse pedaling detection element is additionally arranged for distinguishing full reverse pedaling from semi reverse pedaling, so that a controller can accurately distinguish full reverse pedaling from semi reverse pedaling, and the sewing effect and the sewing efficiency are further improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a speed control system according to an embodiment of the present invention.
This speed governing system locates on the sewing machine, includes:
a moving member 1 provided in a governor of a sewing machine, for being located at a return-to-center position when the governor is not stepped on, moving within a preset forward stepping moving area when being stepped on forward, and moving within a preset backward stepping moving area when being stepped on backward; wherein, the moving degree of the moving component 1 represents the stepping degree of the speed governor;
a position detection element 2 for detecting the position of the moving member 1 and generating a voltage signal indicating the position of the moving member 1;
a full reverse-pedaling detection element 3 for generating a full reverse-pedaling signal when detecting that the speed governor is reversely pedaled to the bottom;
a controller 4 connected to the position detecting element 2 and the full reverse stepping detecting element 3, for controlling the sewing machine to perform a forward stepping function when it is determined that the speed governor is being stepped on based on the voltage signal; when the speed regulator is determined to be reversely stepped according to the voltage signal, if a full reverse stepping signal is not received, controlling the sewing machine to execute a semi-reverse stepping function; and if the full reverse stepping signal is received, controlling the sewing machine to execute a full reverse stepping function.
It should be noted that the preset of the present application is set in advance, and only needs to be set once, and the reset is not needed unless the modification is needed according to the actual situation.
Specifically, the speed governing system of this application includes moving part 1, position detecting element 2, full backpedaling detecting element 3 and controller 4, and its theory of operation is:
the application is provided with a moving part 1 in a speed regulator of a sewing machine. When the governor is not stepped on (by non-stepped on is meant neither forward nor backward), the moving member 1 is in the neutral position. When the speed governor is positively stepped on, the moving member 1 moves within a positive stepping movement region set in advance, and the degree of movement of the moving member 1 indicates the positive stepping degree of the speed governor, that is, the greater the positive stepping degree of the speed governor, the farther the moving member 1 is from the neutral position (the greater the degree of movement). When the speed governor is reversely stepped on, the moving member 1 moves in a previously set reverse stepping movement region, and similarly, the degree of movement of the moving member 1 indicates the degree of reverse stepping on the speed governor.
For a governor in a back-pedaled state, it is divided into two cases: the governor is not bottomed and is bottomed. When the speed regulator is not stepped to the bottom, the speed regulator is considered to be in a semi-reverse stepping state; when the speed regulator is stepped on to the bottom, the speed regulator is considered to be in a full reverse stepping state.
It can be seen that the position of the moving member 1 can indicate the stepping state of the governor (no stepping or forward stepping or semi-backward stepping or full backward stepping), so the present application is provided with the position detecting element 2. The position detection element 2 can detect the position where the moving member 1 is located, and generate a voltage signal indicating the position where the moving member 1 is located. That is, the voltage signal generated by the position detection element 2 has a one-to-one correspondence relationship (simply referred to as a voltage position correspondence relationship) with the position of the moving member 1, so that the position of the moving member 1 can be determined based on the voltage signal generated by the position detection element 2 and the voltage position correspondence relationship.
Based on this, the present application is provided with a controller 4 connected to the position detection element 2, and the position detection element 2 transmits the generated voltage signal to the controller 4. After receiving the voltage signal, the controller 4 first determines the position of the moving member 1 based on the voltage-position correspondence, and then determines the stepping state and stepping degree of the governor based on the position of the moving member 1. In order to prevent the controller 4 from erroneously distinguishing the full reverse step from the half reverse step based on the voltage signal output from the position detecting element 2, the controller 4 determines the stepping state of the governor according to the position of the moving member 1, that is, determines whether the governor is in the non-stepping state or the forward stepping state or the reverse stepping state. As for whether the speed regulator is in a positive and negative pedaling state or a negative and reverse pedaling state, the speed regulator is additionally provided with a full reverse pedaling detection element 3. The full back-stepping detection element 3 generates a full back-stepping signal only when it is detected that the governor is back-stepped to the bottom, thereby accurately distinguishing the full back-stepping from the half back-stepping.
The controller 4 controls the sewing machine to perform a normal-stepping function (e.g., a sewing function) if it is determined that the governor is being stepped on. For sewing, the larger the forward stepping degree of the governor is, the faster the controller 4 controls the sewing speed of the sewing machine (specifically, the faster the rotation speed of the motor controlling the sewing machine).
If the controller 4 determines that the speed regulator is reversely stepped, the controller controls the sewing machine to execute a semi-reverse stepping function (such as a presser foot lifting function) when not receiving a full reverse stepping signal; when the full reverse treading signal is received, the sewing machine is controlled to execute a full reverse treading function (such as a thread cutting function), so that the switching of different special functions of the sewing machine is realized by changing the reverse treading degree of the speed regulator.
The invention provides a speed regulating system, comprising: the moving component is arranged in a speed regulator of the sewing machine and is used for being positioned at a return middle position when the speed regulator is not stepped, moving in a preset forward stepping moving area when the speed regulator is stepped positively and moving in a preset backward stepping moving area when the speed regulator is stepped negatively; wherein the degree of movement of the moving member indicates the degree of stepping on the speed governor; a position detection element for detecting a position of the moving member and generating a voltage signal indicating the position of the moving member; the full reverse pedaling detection element is used for generating a full reverse pedaling signal when detecting that the speed regulator is reversely pedaled to the bottom; the controller is connected with the position detection element and the full reverse stepping detection element and is used for controlling the sewing machine to execute a forward stepping function when the speed regulator is determined to be positively stepped according to the voltage signal; when the speed regulator is determined to be reversely stepped according to the voltage signal, if a full reverse stepping signal is not received, controlling the sewing machine to execute a semi-reverse stepping function; and if the full reverse stepping signal is received, controlling the sewing machine to execute a full reverse stepping function.
It can be seen that, in the application, the full reverse stepping and the half reverse stepping are not distinguished by the voltage value of the position detection element, but a full reverse stepping detection element is additionally arranged (detection principle: when the speed regulator is not reversely stepped to the bottom, the reverse stepping degree of the speed regulator is in half reverse stepping, and when the speed regulator is reversely stepped to the bottom, the reverse stepping degree of the speed regulator is in full reverse stepping). The full reverse pedaling detection element is used for detecting whether the speed regulator is reversely pedaled to the bottom or not, and a full reverse pedaling signal is generated when the speed regulator is detected to be reversely pedaled to the bottom, so that the controller can accurately distinguish full reverse pedaling and half reverse pedaling, and the sewing effect and the sewing efficiency are improved.
On the basis of the above-described embodiment:
referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of another speed regulating system according to an embodiment of the present invention, and fig. 3 is a schematic structural diagram of a hall mounting position according to an embodiment of the present invention.
As a preferred embodiment, the moving member 1 includes:
the rocker arm is arranged in the speed regulator;
a magnetic steel fixed at one end of the rocker arm;
and the position detection element 2 includes:
the linear Hall sensor H1 is arranged in the speed regulator and is used for generating a return voltage signal when the magnetic steel is positioned at a return position; generating a positive stepping voltage signal when the magnetic steel moves in a preset positive stepping movement area; generating a reverse stepping voltage signal when the magnetic steel moves in a preset reverse stepping movement area; wherein, the voltage value of the positive stepping voltage signal is larger than the voltage value of the return neutral voltage signal and is larger than the voltage value of the reverse stepping voltage signal.
Specifically, rocking arm and magnet steel are chooseed for use to moving part 1 of this application, and linear hall sensor H1 is chooseed for use to position detection element 2, and its theory of operation is:
the rocker arm is arranged in the speed regulator and swings along with the position change of the speed regulator. The magnetic steel is fixed at one end of the rocker arm and swings along with the swinging of the rocker arm. The linear Hall sensor H1 is arranged in the speed regulator, and is used for detecting the position of the magnetic steel and outputting a voltage signal representing the position of the magnetic steel.
It should be noted that the voltage value of the forward stepping voltage signal generated by the linear hall sensor H1 when the magnetic steel moves in the forward stepping movement region > the voltage value of the return voltage signal generated by the linear hall sensor H1 when the magnetic steel is located at the return position > the voltage value of the return stepping voltage signal generated by the linear hall sensor H1 when the magnetic steel moves in the return stepping movement region. The larger the positive stepping degree of the speed regulator is, the larger the voltage value of the positive stepping voltage signal generated by the linear Hall sensor H1 is; the larger the degree of back-stepping of the governor, the smaller the voltage value of the back-stepping voltage signal generated by the linear hall sensor H1, and the controller 4 determines the stepping state and the stepping degree of the governor from the voltage signal.
Based on this, the movable range of the magnetic steel and the installation position of the linear hall sensor H1 are as shown in fig. 3, and the dotted line region is the movable range of the magnetic steel when the speed governor is stepped on. The position B is the return-to-center position of the magnetic steel when the speed regulator is not stepped, the position AB is the moving range of the magnetic steel when the speed regulator is positively stepped, and the position BC is the moving range of the magnetic steel when the speed regulator is reversely stepped. The linear hall sensor H1 is fixed at position B.
It can be seen that the present application designs the moving part 1 and the position detecting element 2 based on the principle of the hall effect, thereby realizing the position detection of the moving part 1 by the position detecting element 2.
As a preferred embodiment, the full back-pedaling detection element 3 comprises:
a switch Hall sensor H2 arranged in the speed regulator for detecting whether the magnetic steel reaches the position indicating that the speed regulator is reversely stepped to the bottom, if so, a low level signal is generated; if not, a high level signal is generated.
Specifically, based on the magnet steel setting of above-mentioned embodiment, the full anti-detection element 3 of stepping on of this application chooses switch hall sensor H2 for use, and its theory of operation is:
as shown in fig. 3, when the degree of backward stepping of the speed governor is gradually increased but the speed governor is not stepped to the bottom, the magnetic steel moves from the B position to the C position (not to the C position); when the speed regulator is reversely stepped to the bottom, the magnetic steel moves to the C position. Therefore, the switching hall sensor H2 is fixed at the C position. If the magnetic steel reaches the position C which indicates that the speed governor is reversely stepped to the bottom, the switch Hall sensor H2 generates a low level signal; if the magnetic steel does not reach the C position, the switch Hall sensor H2 generates a high level signal. That is, when the switch hall sensor H2 generates a low level signal, it indicates that the governor is in a full back-pedaled state; when the switch Hall sensor H2 generates a high level signal, the speed governor is in a semi-reverse pedaling state.
Suppose VH1Is the output voltage, V, of the linear Hall sensor H10Is the output voltage V of the linear Hall sensor H1 when the magnetic steel is at the centering positionH2To switch the output voltage of the hall sensor H2. The process that the controller 4 determines the stepping state of the speed regulator according to the voltage signals of the linear hall sensor H1 and the switch hall sensor H2 is specifically as follows:
step S1: obtaining V from a linear Hall sensor H1H1While V is acquired from the switching Hall sensor H2H2；
Step S2: will VH1And V0By comparison, if VH1＞V0Determining that the sewing machine is currently in a forward stepping state, and controlling the sewing machine to sew at a corresponding speed; if VH1＜V0Then, judge VH2If the voltage level is high level, determining that the sewing machine is in semi-reverse pedaling currently, and controlling the sewing machine to execute a presser foot lifting command; if not, determining that the sewing machine is currently in full reverse stepping, and controlling the sewing machine to execute a thread cutting command.
Step S3: judging whether the sewing of the sewing machine is finished, if not, returning to the step S1 until the sewing of the sewing machine is finished.
Therefore, the speed regulator has the advantages of simple structure, simplicity and convenience in installation and capability of realizing accurate control of the controller 4.
In addition, as shown in fig. 2, the main control unit of the controller 4 of the present application is a single chip microcomputer, and the single chip microcomputer interacts with the speed governor and the operation panel on one hand, and controls the motor and the electromagnet of the sewing machine by means of a power device on the other hand. The controller 4 is also internally provided with a power supply module for supplying power to the speed regulator and the singlechip.
As a preferred embodiment, the governor system further includes: a shielding sheet fixed on the magnetic steel;
the full back-stepping detection element 3 then comprises:
the photoelectric switch is arranged in the speed regulator and used for detecting whether the shielding sheet reaches a position indicating that the speed regulator is reversely stepped to the bottom or not, and if so, a low-level signal is generated; if not, a high level signal is generated.
Specifically, in addition to the above-described embodiment that employs the switch hall sensor H2 to distinguish between half-reverse pedaling and full-reverse pedaling, the present application has other ways to distinguish between half-reverse pedaling and full-reverse pedaling:
this application is fixed with the matte on magnet steel, and the detection element 3 chooseed for use photoelectric switch is stepped on in the whole anti-reflection. The magnetic steel moves to the C position when the speed regulator is reversely stepped to the bottom, so the photoelectric switch is fixed at the C position. When the magnetic steel does not move to the position C, the shielding sheet cannot shield the light energy required by the conduction of the photoelectric switch, and the photoelectric switch is in a conduction state at the moment to generate a high-level signal. When the magnetic steel moves to the position C, the shielding sheet just covers the light energy required by the conduction of the photoelectric switch, and the photoelectric switch is in an off state at the moment to generate a low level signal. That is, when the photoelectric switch generates a low level signal, the speed governor is in a full reverse pedaling state; when the photoelectric switch generates a high level signal, the speed regulator is in a semi-reverse pedaling state.
As to the specific manner of distinguishing the half reverse pedaling from the full reverse pedaling, the present application is not particularly limited, and it is sufficient that a signal indicating the full reverse pedaling is output when the speed governor is reversely pedaled to the bottom.
As a preferred embodiment, the controller 4 is connected with an operation panel of the sewing machine;
the controller 4 is further configured to control the operation panel to display a governor abnormality message if the full back-stepping detection element 3 outputs a low level signal when the voltage value of the voltage signal output from the linear hall sensor H1 is greater than the voltage value of the return voltage signal.
Further, considering that the full reverse stepping detection element 3 should output a high level signal when the sewing machine is currently in the forward stepping state, if the full reverse stepping detection element 3 outputs a low level signal in this case, it is considered that the governor is abnormal. Therefore, after the controller 4 of the present application determines that the voltage value of the voltage signal output by the linear hall sensor H1 is greater than the voltage value of the return voltage signal, before determining that the sewing machine is currently being stepped on, the controller 4 further determines whether the full-reverse stepping detection element 3 outputs a high level signal, and if so, executes the step of determining that the sewing machine is currently being stepped on, and controlling the sewing machine to sew at a corresponding speed; if not, the control operation panel displays the abnormal message of the speed regulator for the staff to check, and informs the staff that the speed regulator is abnormal.
As a preferred embodiment, the governor system further includes:
an alarm device connected to the controller 4; the controller 4 is also used for controlling the alarm device to give an alarm while controlling the operation panel to display the abnormal message of the speed regulator.
Further, the speed regulating system of the application also comprises an alarm device controlled by the controller 4. The controller 4 controls the operation panel to display the abnormal message of the speed regulator and controls the alarm device to give an alarm so as to inform a worker of the abnormal condition of the speed regulator in time under the condition that the worker does not check the operation panel.
As a preferred embodiment, the alarm means comprises an indicator light or a buzzer.
Specifically, the alarm device of the present application may select an indicator light (alarm function is realized by changing on/off state or lighting color), or may select but not only be limited to a buzzer, and the present application is not particularly limited herein.
