In the present embodiments, numerous specific details are provided to provide a thorough understanding of embodiments of the utility model; however, it will be apparent to one skilled in the art that the present utility model may be practiced without one or more of these specific details; in other instances, well-known details are not shown or described in order to avoid obscuring the utility model. The technical content and detailed description of the present utility model are as follows in conjunction with the accompanying drawings:
referring to FIG. 1, a block diagram of a motor type tape feeder 10 according to the present utility model is shown; please refer to fig. 2, which is an external view of the motor-type belt feeding device 10 and the sewing device 20 of the present utility model. The motor type tape feeder 10 of the present utility model is applied to a sewing device 20 (e.g., a sewing machine), the sewing device 20 includes a spindle motor 202, a sewing needle 204, a needle plate 206, and any other components that may not be shown in fig. 1 and 2, but which constitute, for example, a sewing machine, the motor type tape feeder 10 includes a spindle encoder 102, a controller 104, a stepping motor driving circuit 106, a stepping motor 108, a feed roller 110, and a stepping motor encoder 118, which are electrically connected or connected to each other. The spindle encoder 102 is a rotary encoder, the stepper motor encoder 118 is a rotary encoder, and the controller 104 is a microprocessor or a microcontroller.
After a main power switch (not shown in fig. 1 and 2) of the sewing device 20 is turned on, if a start/stop button (not shown in fig. 1 and 2) of the sewing device 20 is turned on, the main shaft motor 202 is driven to drive the sewing needle 204 to pass back and forth through the needle plate 206 for sewing operation.
Referring to FIG. 3, a comparison of the rotation angle of the spindle motor 202 and the position of the sewing needle 204 according to an embodiment of the present utility model is shown; please refer to fig. 1 and fig. 2 at the same time. The position of the needle 204 is related to a rotation angle of the spindle motor 202 when the spindle motor 202 is driven to drive the needle 204 back and forth through the needle plate 206 for performing a sewing operation. When the rotation angle of the spindle motor 202 is 0 degrees or 360 degrees, the position of the sewing needle 204 is at a first position P1; when the rotation angle of the spindle motor 202 is 90 degrees or 270 degrees, the position of the sewing needle 204 is at a second position P2; when the rotation angle of the spindle motor 202 is 180 degrees, the position of the sewing needle 204 is at a third position P3. In one embodiment of the present utility model, but not limiting the present utility model, the third position P3 is higher than the second position P2, the second position P2 is higher than the first position P1, and the position of the needle plate 206 is between the second position P2 and the first position P1 (e.g. near the second position P2 but slightly lower than the second position P2).
When the rotation angle of the spindle motor 202 is between 0 degrees and 90 degrees, or when the rotation angle of the spindle motor 202 is between 270 degrees and 360 degrees, the position of the sewing needle 204 is between the first position P1 and the second position P2, and the sewing needle 204 is in a state of passing through the needle plate 206 (i.e., at least a portion of the sewing needle 204 passes through the needle plate 206), so that the belt cannot be fed. When the rotation angle of the spindle motor 202 is between 90 degrees and 270 degrees, the position of the sewing needle 204 is between the second position P2 and the third position P3, and the sewing needle 204 is not passing through the needle plate 206 (i.e., the entire sewing needle 204 is separated from the needle plate 206), so that a belt (e.g., an elastic belt) can be fed. Referring to fig. 3, the present utility model defines a belt angle interval A1 as follows: the spindle motor 202 drives the sewing needle 204 during the rotation angle of the spindle motor 202 within the tape feed angle interval A1 (e.g., between 90 degrees and 270 degrees as described above) so that the sewing needle is located at a position not to pass through the needle plate 206.
Referring to fig. 1, the spindle encoder 102 is configured to sense the rotation angle of the spindle motor 202 to generate a rotation angle signal 112. The controller 104 is configured to receive the rotation angle signal 112 transmitted by the spindle encoder 102 and obtain the rotation angle of the spindle motor 202 based on the rotation angle signal 112 to generate a stepper motor control signal 114 during the tape angle interval A1. For the above embodiment, the controller 104 can obtain the current rotation angle of the spindle motor 202 via the rotation angle signal 112, and generate the stepper motor control signal 114 only during the rotation angle is, for example, between 90 degrees and 270 degrees (i.e., the belt feeding angle interval A1).
The stepper motor driver circuit 106 is configured to receive the stepper motor control signal 114 transmitted by the controller 104 and generate a stepper motor drive signal 116 during the tape angle interval A1 based on the stepper motor control signal 114. The stepper motor 108 is configured to receive the stepper motor drive signal 116 transmitted by the stepper motor drive circuit 106 and to be driven based on the stepper motor drive signal 116 during the tape angle interval A1. The feed roller 110 is configured to be rotated by the stepper motor 108 being driven during the belt angle interval A1, thereby feeding a belt.
In one embodiment of the present utility model, but not limiting the present utility model, the stepper motor driving circuit 106 is configured to evenly transmit the pulses included in the stepper motor driving signal 116 to the stepper motor 108 during the tape angle interval A1 to drive the stepper motor 108, so that the tape feed roller 110 can be constantly driven by the stepper motor 108 during the tape angle interval A1 to uniformly feed a tape, as described in detail below:
the belt feeding angle interval A1 is between a first angle (which may be set by a user according to the sewing device 20, for example, 90 degrees) and a second angle (which may be set by a user according to the sewing device 20, for example, 270 degrees), the second angle is larger than the first angle, the number of the pulses is a first number (which may be set by a user according to the need, for example, 50), the second angle is reduced by the first angle by an angle difference (for example, 270-90=180), and the angle difference is divided by the first number by a pitch degree (for example, 180/50=3.6). The stepper motor drive circuit 106 is configured to send one of the pulses to the stepper motor 108 each time the spindle motor 202 rotates the pitch number of degrees (e.g., 3.6 degrees) during the tape feed angle interval A1 to drive the stepper motor 108, whereby the tape feed roller 110 is constantly driven by the stepper motor 108 during the tape feed angle interval A1 and uniformly feeds tape.
Briefly, in the above embodiment, after the spindle motor 202 is rotated 90 degrees to completely separate the sewing needle 204 from the surface of the needle plate 206, the stepper motor 108 receives a pulse to operate every 3.6 degrees of rotation of the spindle motor 202 until the spindle motor 202 is rotated 270 degrees. Thus, after the 50 th pulse is received by the stepping motor 108, the stepping motor 108 stops being driven. Thereby, the feeding roller 110 stops feeding the belt.
Generally, the more the first number of pulses, the faster the stepper motor 108 rotates. Thus, for example, the longer the elastic band is fed by the feed roller 110, the looser the sewn elastic band is for the same operating condition of the sewing needle 204, e.g., 150 pulses result in looser elastic band than 50 pulses result.
In another embodiment of the present utility model, the stepper motor driving circuit 106 is configured to unevenly transmit the pulses included in the stepper motor driving signal 116 to the stepper motor 108 during the belt angle interval A1 by programming, so as to drive the stepper motor 108, such that the belt feeding roller 110 can be non-constantly driven by the stepper motor 108 to unevenly feed the belt during the belt angle interval A1, thereby achieving the purpose of adjusting, for example, different positions of the elastic belt requiring different tightness.
The utility model provides a tape feeder with simple structure and easy operation. The stepper motor 108 is continuously controlled in the manner described above and speed adjustment is performed following the speed of the spindle motor 202, and the tape feed control described above is also applicable to a post-stepping tug.
The foregoing description is merely illustrative of the present utility model and is not intended to limit the scope of the utility model, i.e. the utility model is not limited to the specific embodiments described herein. The present utility model is capable of other and further embodiments and its several details are capable of modification and variation in light of the present utility model, as will be apparent to those skilled in the art, without departing from the spirit and scope of the utility model as defined in the appended claims. In summary, the structure of the present utility model is not found in the similar products and is disclosed for use, and has industrial applicability, novelty and progress.
