Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

The inventors of the present application have found, through long-term research: in the technology of the hosiery machine, in order to meet the knitting requirements of different parts of the hosiery (such as heel parts and toe parts), the needle cylinder of the hosiery machine can be required to operate continuously and move in a reciprocating manner. The main control unit and the servo controller are independent parts, and long wire harnesses are connected between the main control unit and the servo controller, so that if the main control unit transmits pulse signals to the servo controller to control the servo motor to operate, the pulse signals between the main control unit and the servo controller are easily transmitted to cause time delay, and the main control unit and the servo controller are easily influenced by an external interference source. When the hosiery machine stops at a high speed or rotates forwards and backwards quickly, the slow pulse signal transmission will cause the deceleration stroke to be lengthened, and the fast pulse signal transmission will cause the needle cylinder to overshoot and reverse, causing mechanical faults such as firing pin and the like. This not only seriously affects the productivity of the hosiery knitting machine, but also causes the produced hosiery to be of uneven quality. To solve these problems, the present application proposes the following embodiments.

The syringe 140 is drivingly connected to the servo motor 130, and the servo motor 130 may be used to drive the syringe 140 in rotation.

In some embodiments, the operation box 180 and the main controller 150 may also be combined to form a human-computer interaction terminal device, which is connected with the servo controller 170 of the hosiery knitting machine 100 through the serial peripheral communication circuit 160. This facilitates the simplification of the structure of the hosiery knitting machine 100 and the ease of operation.

In this embodiment, the operation box 180 may be used to set the hosiery knitting parameters. The hosiery knitting parameters may include at least one of a pattern or design, a weave density, a shape, and a weave speed. The pattern or design is, for example, the overall pattern or design of the sock, or the partially dotted pattern or design, or the pattern or design may be a three-dimensional pattern or shape. The pattern or design may also include parameters such as the weaving position, length and density of the textile threads with different colors. The weave density is, for example, the number of threads in a given length (e.g., 10 cm), and in this embodiment, the weave density may be the same or different at different parts of the knitted sock. The shape includes, for example, the style, length, thickness, circumference, etc. of the sock. The weaving speed includes, for example, a thread feeding speed of a textile thread or a knitting speed of the needle cylinder 140.

In this embodiment, the main controller 150 may also be configured to analyze the servo parameters based on the hosiery knitting parameters. For example, after receiving the hosiery knitting parameters set by the operation box 180, the main controller 150 may further analyze the hosiery knitting parameters to obtain corresponding servo parameters. The servo parameters may include, for example, at least one of direction of travel, speed, and position information. The position information includes, for example, an initial operation position, a stop position, or a reverse rotation position at the time of the reciprocating motion.

In the present embodiment, the servo controller 170 is used to control the operation of the servo motor 130. In some embodiments, the servo controller 170 receives the servo parameters transmitted by the main controller 150, forms corresponding pulse signals based on the servo parameters, and transmits the corresponding pulse signals to the servo motor 130, so that the servo motor 130 performs corresponding movements according to the received pulse signals.

In this embodiment, the servo controller 170 may be further configured to obtain current position information of the servo motor 130, and plan a moving track of the servo motor 130 based on the current position information and the servo parameters. In some embodiments, each time the hosiery knitting machine 100 knits a sock, the needle cylinder 140 of the hosiery knitting machine 100 begins knitting from the starting position. If the starting position is fixed, the servo motor 130 may drive the needle cylinder 140 to return to the starting position each time a sock is knitted, and the servo controller 170 obtains the current position information of the servo motor 130, that is, the position information of the servo motor 130 corresponding to the starting position of the needle cylinder 140. If the starting position is changed, that is, each time the syringe 140 starts to knit from a new starting position, the servo controller 170 obtains the current position information of the servo motor 130, that is, the position information of the servo motor 130 corresponding to the new starting position of the syringe 140.

The current position information may be, for example, the rotational direction and angle at which the servo motor 130 drives the syringe 140 connected thereto to return to the initial position. In a specific application scenario, for example, the servo controller 170 acquires the current position information of the servo motor 130 as being clockwise offset by 90 ° with respect to the position corresponding to the starting position of the syringe 140, that is, acquires the current position information as being counterclockwise by 90 °.

In this embodiment, the servo controller 170 may plan the operation track of the servo motor 130. The trajectory is, for example, the rotational direction, angle, and speed of the servo motor 130. In some embodiments, the servo motor 130 is required to reciprocate, and further includes position information of each reverse position of the multiple reciprocating movements.

In some embodiments, after acquiring the current position information, the servo controller 170 may further control the servo motor 130 to return to the initial operating position based on the current position information, that is, control the servo motor 130 to drive the syringe 140 to return to the initial position. For example, in the particular application scenario described above, the servo controller 170 may control the servo motor 130 to rotate 90 ° in a counterclockwise direction to drive the syringe 140 back to the starting position. Therefore, the deviation between the stop position of the servo motor 130 and the initial operation position of the servo motor 130 set at this time caused by the change of the stop position of the servo motor 130 after the previous weaving is completed can be avoided, and the positioning accuracy of the servo motor 130 is further improved.

In this embodiment, the user can use the operation box 180 to set up the hosiery knitting parameters and transmit to the main controller 150, and the main controller 150 can send the servo parameters obtained by analyzing the hosiery knitting parameters to the servo controller 170 in advance, so that the servo controller 170 can plan the running track of the servo motor 130 in advance and adopt the optimal parking control strategy, and therefore the user can use the machine simply and quickly, the execution speed is higher, the positioning accuracy is more accurate, and the production efficiency of the hosiery knitting machine 100 can be effectively improved.

In some embodiments, the master controller 150 may also perform a simulated demonstration based on the set hosiery parameters. For example, the display device 1812 or the touch panel of the console box 180 may be used for display. Therefore, the user can more visually check the set sock knitting parameters, and the working efficiency is improved.

In this embodiment, the servo controller 170 may further include a monitoring circuit 171. The monitoring circuit 171 may be used to monitor and acquire the operating state information of the servo motor 130, and transmit the operating state information to the main controller 150 through the serial peripheral communication circuit 160. The operation state information may reflect a real-time operation state of the servo motor 130, such as whether the servo motor 130 is operating, a rotation direction of the servo motor 130, a rotation speed, position information, and the like. The operating status information of the servo motor 130 may also reflect the operating status of the syringe 140, and may be used to determine whether the parking position of the syringe 140 is accurate, and whether the syringe 140 overshoots or reverses.

The operating state information may also include, for example, fault information of the servo motor 130. Failure of the servo motor 130 may be caused by long-term maintenance, human factors, or sudden reasons, and the servo motor 130 and other parts of the hosiery knitting machine 100 may be damaged if not handled in time. In some embodiments, the servo controller 170 may also control the servo motor 130 to stop operating when acquiring the fault information.

In this embodiment, the servo controller 170 may also transmit failure information of the servo motor 130 to the main controller 150. In some embodiments, the fault information may be only a simple fault signal for quickly indicating a fault in the servo motor 130. In other embodiments, the failure information may also include a specific reason for the failure of the servo motor 130, so that a user can take timely and targeted measures to remove the failure.

The main controller 150 may also send a stop signal to the servo controller 170 upon receiving the failure information. The servo controller 170 controls the servo motor 130 to stop operating after receiving the stop signal. By sending a stop signal to control the servo motor 130 to stop operating, further damage to the servo motor 130 may be avoided, as well as damage to the syringe 140 to which it is coupled.

In some embodiments, hosiery knitting machine 100 may also be provided with an alarm (not shown), such as an LED light or a buzzer or the like. The alarm may be connected to the main controller 150 or may be connected to the servo controller 170. The alarm is configured to receive alarm information sent by the main controller 150 or the servo controller 170 when the main controller 150 or the servo controller 170 acquires the fault information, and send a corresponding alarm according to the alarm information. This effectively reminds the user to check the hosiery knitting machine 100 in time and to remove the malfunction.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
