Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
The invention patent application CN201910087806.1 discloses a multicolor rope embroidery machine and a machine head thereof, wherein the embroidery machine comprises a frame, a machine head and a plurality of rope racks. The side edge of the presser foot part of the rope embroidery presser foot is provided with a rope passing hole, and the center of the presser foot part of the rope embroidery presser foot is provided with a needle passing hole. The embroidery rope penetrates through the rope frame, penetrates into the rope passing hole of the rope embroidery presser foot from the lower part of the crossbeam and penetrates out of the lower end of the needle passing hole of the rope embroidery presser foot. The needle penetrates from the upper end of the needle passing hole and then penetrates out from the lower end of the needle passing hole. Under the existing structure, the invention installs the thread scissors on the embroidery machine head, and the thread scissors are arranged under the condition of not interfering the movement of the needle and the thread embroidery presser foot. The string shears may be movable in a non-vertical direction, such as in an inclined direction, or in a partially vertical direction and a partially inclined direction. The thread scissors can adopt the thread scissors structure of the existing embroidery machine, such as consisting of a movable knife and a fixed knife. When the fixed knife and the movable knife are closed, the rope-shaped ornaments can be cut off by the cutting edge of the movable knife. The thread cutting action of the thread scissors is controlled by the embroidery machine control device.
On the basis, the invention provides an embroidery machine thread cutting method for sewing rope-shaped ornaments. As in fig. 1, the method comprises:
step S01, when the rope thread presser foot is at the lower position, the embroidery thread scissors are controlled to cut off the upper thread, and the hook knife is controlled to hook up the upper thread end and store the upper thread end in the upper thread clamp;
step S02, when the rope thread presser foot moves to the upper position, the rope thread scissors are controlled to move to the rope thread cutting position;
step S03, controlling the rope thread presser foot to move downwards to the upper part close to the rope thread scissors;
and step S04, controlling the rope thread scissors to pull out a rope thread end with a certain length and cutting off the rope thread-shaped ornaments.
After the embroidery pattern is finished, thread cutting is required. Because the rope thread scissors can cut off the rope thread-shaped ornaments with strong toughness, if the thread cutting of the rope thread-shaped ornaments is carried out firstly, the wrong cutting of the upper thread can be caused, the lengths of the thread ends of the cut upper thread are different, and the quality of the embroidery is influenced. If the mistaken shearing is to be avoided, other hooking parts are required to be arranged independently to hook the rope-shaped ornament away from the upper thread, on one hand, the hooking parts are required to be additionally arranged and the control steps are increased in the process, on the other hand, the possibility that the rope-shaped ornament and the upper thread are hooked simultaneously exists, and finally the mistaken shearing cannot be avoided. In order to avoid confusion of thread cutting, the method of the invention separates the thread cutting time of the upper thread and the rope thread and cuts the thread of the upper thread and the rope thread-shaped ornament independently.
The step S01 includes:
step S11, after the needle finishes the embroidery of the last needle track point, the thread presser foot is positioned at the lower position, and the thread scissors are controlled to cut off the upper thread;
and step S12, controlling the hook knife to hook the head of the upper thread and store the head of the upper thread in the upper thread clamp.
After the machine needle finishes the embroidery of the last needle track point, the thread presser foot is positioned at the embroidery position, namely the lower position. At this stage, the embroidery thread scissors on the embroidery machine are controlled to cut off the upper thread. Then, the hook knife hooks the upper thread end. When the hook knife hooks the end of the upper thread, the hook knife can not hook the thread-shaped ornament of the rope. Because the rope-shaped ornament penetrates through the rope passing hole in the side face of the rope presser foot and then penetrates out of the needle passing hole in the middle of the rope presser foot, the presser foot part is in a cone frustum shape with a large upper part and a small lower part, the rope enters the presser foot part in a curve state, the rope-shaped ornament is avoided in space, and the hook knife cannot be hooked by mistake.
The step S02 includes:
step S21, after the upper thread is cut off and hooked, controlling the rope thread presser foot to move from the lower position to the upper position;
in step S22, when the thread presser is moved to the upper position, the thread scissors are controlled to move to the thread cutting position.
And after the upper thread end is hooked, cutting the thread of the rope. The rope thread presser foot is firstly controlled to move from the lower position to the upper position, so that the rope thread scissors can move to the rope thread cutting position under the interference of the rope thread presser foot. The thread cutting position refers to a position where the thread scissors move to a position close to the upper part of the embroidery material, and is not a position where the thread ends are finally cut. The thread scissors stay at the position and wait for further thread cutting instructions to cut threads. The rope thread cutting position is close to the embroidery material as much as possible, so that the rope thread end is not too long and not beautiful, and the rope thread end is easy to pull out, thereby affecting the quality of the embroidery.
In step S03, after the thread trimmer is ready, the thread presser is controlled to move downward from the upper position to the upper position close to the thread trimmer. The upper part of the rope thread scissors is the position which is close to the rope thread scissors and does not interfere the action of the rope thread scissors, and the upper surface of the rope thread scissors and the position above the upper surface of the rope thread scissors are close to the rope thread scissors. The thread presser foot is moved to be close to the thread scissors, which mainly ensures that the thread end of the thread when the thread presser foot is at the lowest position is drawn out when the next stitch after thread cutting is embroidered, thereby reducing the embroidery error and improving the embroidery quality.
In step S04, the string scissors need to be controlled to pull out a string end of a certain length, so as to facilitate cutting the string and avoid the string end being too short to be knotted. The certain length of the rope thread scissors is determined according to the displacement of the rope thread scissors pulling the rope thread-shaped ornament from the rope thread cutting position. The method of the present invention may further set the displacement of the string scissors pulling the string-shaped ornament according to the string end of the desired length before step S01.
The method also comprises a step S05, after the rope-shaped trimming piece is cut off, the rope presser foot is controlled to move to the upper position, and the rope scissors are controlled to return. In one embodiment, the thread presser foot can be controlled to move from the upper position close to the thread presser foot to the upper position, and then the thread scissors can be controlled to return. In another embodiment, the control thread presser foot can move from the upper position close to the thread presser foot to the upper position control, and simultaneously the control thread scissors return. After returning, the embroidery machine executes the embroidery instruction of the next stage.
The method of the invention is mainly applicable to a multicolor rope embroidery machine disclosed in the invention patent application CN201910087806.1, and is not limited to the embroidery machine. The embroidery machine mainly has the following structure: the presser foot rod on the embroidery machine is fixed with a rope thread presser foot which can be used as an upper thread presser foot and a rope thread presser foot allowing the rope thread to pass through simultaneously, and when a machine needle is used for needling, the machine needle with the upper thread is used for puncturing the rope thread and finishing embroidery sewing. The side surface of the foot part of the rope thread presser foot is provided with a rope passing hole allowing the rope thread ornament to penetrate in, and the center of the foot part of the rope thread presser foot is provided with a needle passing hole allowing the rope thread ornament and the needle to penetrate out. The presser foot part structure of the rope thread presser foot is not limited to a cone frustum shape with a large upper part and a small lower part. Specifically, the rope-shaped ornament enters the through-hole in the center of the rope presser foot from the rope-passing hole on the side surface of the rope presser foot and passes out of the through-hole. When the rope thread presser foot presses the embroidery material, the needle penetrates through the needle passing hole to pierce into the rope thread ornament, the rope thread ornament is fixed by the embroidery thread, and an embroidery pattern is formed on the embroidery material along with the movement of the embroidery frame. After the embroidering process is completed, thread cutting is performed. At the moment, the intelligent trimming is carried out by adopting the method.
The method of the present invention is implemented by an embroidery machine thread trimming control apparatus for sewing a string-shaped ornament. As shown in fig. 2, the thread cutting control device comprises an embroidery thread cutting module, a hooking knife hooking module, a thread presser foot module and a thread cutting module. The embroidery thread cutting module is used for controlling the embroidery thread scissors to cut off the upper thread when the rope thread presser foot is at the lower position. The hook knife hooking module is used for controlling the hook knife to hook up the head of the facial suture and store the head of the facial suture in the facial suture clip after the facial suture is cut off. The rope thread presser foot module is used for controlling the rope thread presser foot to move from the lower position to the upper position after the upper thread is cut off and hooked; and after the rope thread scissors move to the rope thread cutting position, the rope thread presser foot is controlled to move from the upper position to the position close to the upper part of the rope thread scissors. The rope thread cutting module is used for controlling the rope thread scissors to move to the thread cutting position when the rope thread presser foot moves to the upper position, and controlling the rope thread scissors to pull out a certain length of rope thread end and cut off the rope thread-shaped ornaments when the rope thread presser foot moves to the position close to the upper part of the rope thread scissors.
