Fig. 1 is a schematic structural diagram of an apparatus for automatically replacing a bobbin according to the present invention, referring to fig. 1, the apparatus for automatically replacing a bobbin in this embodiment includes: a drive structure and a replacement structure 12.
The driving structure includes a first driving structure 111, a second driving structure 112, and a third driving structure 113; the replacement structure is connected to the first drive structure 111, the first drive structure 111 is connected to the second drive structure 112, and the second drive structure 112 is also connected to the third drive structure 113;
the first driving structure 111 is used for driving the replacement structure 12 to move along a first horizontal direction, the second driving structure 112 is used for driving the replacement structure 12 to move along a vertical direction, and the third driving structure 113 is used for driving the replacement structure 12 to move along a second horizontal direction; the first horizontal direction and the second horizontal direction are perpendicular, and the vertical direction is perpendicular to the first horizontal direction and the second horizontal direction respectively.
In particular, the apparatus for automatically replacing a bobbin of the present embodiment is suitable for replacing a device having a bobbin such as an embroidery machine.
The device for automatically replacing the bobbin in the embodiment comprises: a drive structure and a replacement structure 12.
If the shuttle core in the embroidery machine is replaced, the driving structure drives the replacing structure 12 to move to the rotating shuttle box position of the embroidery machine, and the replacing structure 12 replaces the spent shuttle core in the rotating shuttle box of the embroidery machine.
Further, the driving structure includes a first driving structure 111, a second driving structure 112, and a third driving structure 113; the replacement structure 12 is connected to a first drive structure 111, the first drive structure 111 is connected to a second drive structure 112, and the second drive structure 112 is also connected to a third drive structure 113;
the first driving structure 111 is used for driving the replacement structure 12 to move along a first horizontal direction, the second driving structure 112 is used for driving the replacement structure 12 to move along a vertical direction, and the third driving structure 113 is used for driving the replacement structure 12 to move along a second horizontal direction; the first horizontal direction and the second horizontal direction are perpendicular, and the vertical direction is perpendicular to the first horizontal direction and the second horizontal direction respectively.
Specifically, if the bobbin in the embroidery machine is replaced, the first horizontal direction may be the Y-axis direction, for example: the device for automatically replacing the bobbin is positioned in front of the embroidery machine, and the Y-axis direction is a horizontal direction perpendicular to the front of the embroidery machine (i.e., the surface of the embroidery machine facing the user and perpendicular to the ground) and parallel to the ground or horizontal plane. The replacement structure 12 moves along the Y-axis direction, either closer to the embroidery machine or farther from the embroidery machine, that is, the first driving structure 111 drives the replacement structure 12 to move back and forth relative to the front of the embroidery machine, and as will be understood by those skilled in the art, "back and forth" herein refers to "movement closer to the front of the embroidery machine and movement farther from the front of the embroidery machine" and does not refer to movement on the front of the embroidery machine and movement on the back of the embroidery machine.
Accordingly, the vertical movement may be referred to as an X-axis direction, such as: the device for automatically replacing the bobbin is positioned in front of the embroidery machine, and the X-axis direction is the direction parallel to the front surface of the embroidery machine (i.e., the surface of the embroidery machine facing the user and perpendicular to the ground) and perpendicular to the ground or horizontal plane. The replacement structure 12 moves along the X-axis direction, either closer to the ground or farther from the ground, that is, the second driving structure 112 drives the replacement structure 12 to move up and down relative to the ground.
Accordingly, the second horizontal direction motion may be referred to as the Z-axis direction, such as: the device for automatically replacing the bobbin is positioned in front of the embroidery machine, and the Z-axis direction is the direction parallel to the front of the embroidery machine (i.e., the surface of the embroidery machine facing the user and perpendicular to the ground) and parallel to the ground or a horizontal plane. The replacement structure 12 moves along the Z-axis direction, which may be a movement near the left side of the embroidery machine or a movement near the right side of the embroidery machine, that is, the third driving structure 113 drives the replacement structure 12 to move left and right with respect to the embroidery machine.
In other words, the first driving structure 111 drives the replacement structure 12 to move back and forth, the second driving structure drives the replacement structure 12 to move up and down, and the third driving structure 111 drives the replacement structure 12 to move left and right.
Obviously, the first horizontal movement direction, the second horizontal direction and the vertical direction are perpendicular to each other.
A detailed description will be given below of an operation of the apparatus for automatically replacing a bobbin according to the present embodiment, taking a bobbin in a rotating bobbin case of an embroidery machine as an example.
An embroidery machine generally includes a plurality of rotating shuttle boxes, each of which has a shuttle core disposed therein. When the bobbin in one of the rotating shuttle boxes a is used up, the third driving structure 113 drives the replacement structure 12 to move leftwards or rightwards so that the replacement structure 12 moves to the corresponding station of the rotating shuttle box a, then the second driving structure 112 drives the replacement structure 12 to move upwards or downwards so that the replacement structure 12 moves to the right opposite side of the rotating shuttle box a, then the third driving structure 113 drives the replacement structure 12 to move forwards or backwards, finally the replacement structure 12 moves to the corresponding position of the rotating shuttle box a, and the corresponding position of the rotating shuttle box a meets the following conditions: the gripping portion of the replacement structure 12 may grip the spent bobbin in the rotating bobbin case a under the control of the control portion of the replacement structure 12. After the gripping part grips the used bobbin in the rotating shuttle box A, the driving structure drives the replacement structure 12 to move to the bearing container of the used bobbin, the used bobbin is released to the bearing container of the used bobbin, the driving structure drives the replacement structure 12 to move to the bearing container of the unused bobbin, the unused bobbin in the process of gripping from the bearing container of the unused bobbin is gripped by the driving structure, the driving structure drives the replacement structure to move to the corresponding position of the rotating shuttle box A again, and the unused bobbin is placed in the rotating shuttle box A. This completes the replacement of the bobbin in one rotating bobbin case a.
The unused bobbin is a bobbin wound with embroidery thread, and the used bobbin is a bobbin not wound with embroidery thread or a bobbin not required by the embroidery thread wound thereon.
When the bobbin in the rotating shuttle box B also needs to be replaced, the third driving structure 113 drives the replacing structure 12 to move leftwards or rightwards so that the replacing structure 12 moves to the corresponding station of the rotating shuttle box B, then the second driving structure 112 drives the replacing structure 12 to move upwards or downwards so that the replacing structure 12 moves to the right opposite side of the rotating shuttle box B, then the third driving structure 113 drives the replacing structure 12 to move forwards or backwards, finally the replacing structure 12 moves to the corresponding position of the rotating shuttle box B, and the corresponding position of the rotating shuttle box B meets the following conditions: the gripping portion of the replacement structure 12 may grip the spent bobbin in the rotating bobbin case B under the control of the control portion of the replacement structure 12. The driving structure drives the replacing structure 12 to move to the bearing container of the used bobbin, the used bobbin is released to the bearing container of the used bobbin, the driving structure drives the replacing structure 12 to move to the bearing container of the unused bobbin, the unused bobbin in the bearing container of the unused bobbin is grabbed, the driving structure drives the replacing structure to move to the corresponding position of the rotating shuttle box B again, and the unused bobbin is placed in the rotating shuttle box B. The replacement of the bobbin in the rotating bobbin case B is thus completed.
Wherein the unused bobbin-containing receptacles include, but are not limited to, the prior art rotating shuttle stack.
It will be appreciated by those skilled in the art that the sequence of operation of the drive structures described above is only one type of operation that may be accomplished, and that the sequence of operation of the drive structures described above may be interchanged, and that each drive structure may be operated multiple times while changing the bobbin in the same rotating shuttle box until the changing structure 12 is moved to a predetermined position, which may be: corresponding positions of the rotating shuttle boxes, containing containers with used shuttle cores, containing containers without finished shuttle cores, and the like.
In addition, it should be understood by those skilled in the art that the working process of each driving structure may also be as follows: the first driving structure 111 and the second driving structure 112 operate simultaneously, such as: after the third driving structure drives the replacement structure 12 to the corresponding station of the rotating shuttle box, the first driving structure 111 and the second driving structure 112 may operate simultaneously to move the replacement structure 12 to the corresponding position of the corresponding rotating shuttle box. The movement path of the replacement structure 12 is not limited to a straight line, but is a movement path after the two driving structures are driven together.
Of course, the working process of each driving structure can also adopt the following working modes: the motors of the first driving structure 111, the second driving structure 112 and the third driving structure 113 may be operated simultaneously, so that the replacement structure 12 may move in three directions simultaneously, and the movement track of the replacement structure 12 is not limited to a straight line, but is a movement track after the three driving structures are driven together.
According to the working process, the automatic bobbin replacing device can sequentially complete the replacement of the bobbin in the rotating shuttle boxes.
Those skilled in the art will appreciate that the current automatic bobbin-changing device can perform bobbin-changing for any rotating shuttle box within the stroke of the current automatic bobbin-changing device.
The device for automatically replacing the bobbin in the embodiment enables one device for automatically replacing the bobbin to replace the bobbin in a plurality of rotating shuttle boxes in the stroke of the device through the arrangement of the first driving structure 111, the second driving structure 112 and the third driving structure 113, and does not need to correspondingly arrange one device for replacing the bobbin for one rotating shuttle box in the prior art, so that the installation cost of the device is low, the efficiency of replacing the bobbin is high, and the production efficiency is improved.
In addition, the driving structure in this embodiment drives the replacement structure to move to a predetermined position, which can be precisely controlled by a program, and the precision of the replacement structure reaching different predetermined positions (such as positions corresponding to different rotating shuttle boxes) can be individually set and adjusted.
The device for automatically replacing the shuttle peg provided in the embodiment comprises: a drive structure and a replacement structure; the driving structure comprises a first driving structure, a second driving structure and a third driving structure; the replacement structure is connected with the first driving structure, the first driving structure is connected with the second driving structure, and the second driving structure is also connected with the third driving structure; the first driving structure is used for driving the replacement structure to move along a first horizontal direction, the second driving structure is used for driving the replacement structure to move along a vertical direction, and the third driving structure is used for driving the replacement structure to move along a second horizontal direction; the first horizontal direction and the second horizontal direction are perpendicular, and the vertical direction is perpendicular to the first horizontal direction and the second horizontal direction respectively.

The following describes the automatic bobbin-changing device in the previous embodiment in detail using several specific embodiments.
First, the "first driving structure, second driving structure, and third driving structure" in the above embodiment will be described.
Fig. 2 is a side view of the device for automatically replacing a bobbin according to the present invention, fig. 3 is a front view of the device for automatically replacing a bobbin according to the present invention, fig. 4 is a plan view of the device for automatically replacing a bobbin according to the present invention, and referring to fig. 2 to 4, a first driving structure 111 of the device for automatically replacing a bobbin according to the present embodiment includes: the first linear guide 21, the first lead screw 22, the first motor 23, the first motor base 24 and the first linear guide base 25;

Specifically, the first motor 23 may employ a stepping motor, and the first motor 23 may also employ a servo motor.
The first motor 23 rotates to drive the first screw rod of the first screw rod 22 to rotate, the rotation of the first screw rod drives the first screw rod nut on the first screw rod to do linear motion, the first screw rod nut drives the first sliding block on the first linear guide rail 21 to do linear motion, and meanwhile, the first connecting plate arranged on the first sliding block follows the first sliding block to do linear motion.
Since the replacement structure 12 is connected to the first connecting plate, the first connecting plate moves to drive the replacement structure 12 to move.
As described in the previous embodiment, the first driving structure 111 is used to drive the replacement structure 12 to move along the first horizontal direction, which may be a horizontal direction perpendicular to the front surface of the embroidery machine (i.e., the surface of the embroidery machine facing the user and perpendicular to the ground), that is, the first driving structure 111 is used to drive the replacement structure 12 to move forward or backward.
Thus, when the first motor 23 rotates, the first link plate is moved forward or backward along the first linear guide 21 through a series of transmissions, the replacement structure 12 connected to the first link plate is also moved forward or backward, and thus the first driving structure 111 achieves the purpose of driving the replacement structure 12 to move forward or backward.
The second driving structure 112 of the apparatus for automatically replacing a bobbin of the present embodiment includes: a second linear guide 31, a second lead screw 32, a second motor 33, and a second linear guide base 34;

Specifically, the third motor 41 may employ a stepping motor, and the second motor 41 may also employ a servo motor.
The third motor 41 rotates to drive the first synchronizing wheel 42 to rotate, the second synchronizing wheel 44 rotates through the transmission of the belt 43, the second synchronizing wheel 44 rotates to drive the coaxially connected gear 45 to move on the rack 46, and the gear 45 drives the third connecting plate 47 to do linear motion. Wherein the first synchronizing wheel 42 may be a small synchronizing wheel and the second synchronizing wheel 44 may be a large synchronizing wheel.
As described in the previous embodiment, the third driving structure 113 is used to drive the replacement structure 12 to move along the second horizontal direction, which is perpendicular to the first horizontal direction and the vertical direction, that is, the third driving structure 113 is used to drive the replacement structure 12 to move leftwards or rightwards.
Because the third connecting plate 47 is connected with the second linear guide rail base 34, when the third motor 41 rotates and the third connecting plate 47 moves leftwards or rightwards through a series of transmission, the third connecting plate 47 drives the second linear guide rail base 34 to move leftwards or rightwards, and further drives the whole second driving structure 112 to move leftwards or rightwards, and the first connecting plate of the second driving structure 112 also moves leftwards or rightwards; because the first connecting plate is connected with the first motor base 24, when the first connecting plate moves leftwards or rightwards, the whole first driving structure 111 is driven to move leftwards or rightwards, the first connecting plate included in the first driving structure 111 also moves leftwards or rightwards, and therefore the replacement structure 12 connected with the first connecting plate also moves leftwards or rightwards along with the first connecting plate, and the third driving structure 113 achieves the purpose of driving the replacement structure 12 to move leftwards or rightwards.
