Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and in particular to a traction device for moving the yarn frame of a warping machine. Background Technology

[0002] Most automatic warping machines use a working mode where the main unit is fixed to the ground and the yarn frame moves.

[0003] After the automatic warping equipment completes the warping operation, the yarn frame needs to be manually separated from the main unit. After the yarn frame is installed with the warp beam and the warping material, it can weigh up to 4 tons or more and its length can be close to 5 meters. It is huge and cumbersome, and generally requires two workers to push the yarn frame. This not only causes problems with movement and turning, but also poses a risk to the safety of workers during the operation.

[0004] In some related technologies, workers may use a tractor to move the yarn frame in order to save effort. However, this requires the yarn frame and the tractor to be tied together with ropes beforehand, which is cumbersome. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a traction device for moving the yarn frame of a warping machine, which facilitates connection with the yarn frame.

[0006] According to some embodiments of the present invention, a traction device for moving the yarn frame of a warping machine includes: a frame; a drive wheel disposed on the frame; and a docking mechanism disposed on the frame. The docking mechanism includes a docking member rotatably connected to the frame, a drive member for driving the docking member to rotate in a vertical plane, and an elastic member disposed on the frame and connected to the docking member. The front end of the docking member has a docking hook capable of rotating about the rotation center axis of the docking member.

[0007] The docking hook has an avoidance position and a docking position; the docking hook in the docking position can swing downward under the drive of the drive member when the drive member is running in the first direction to reach the avoidance position, and the docking hook in the avoidance position can swing upward under the drive of the elastic member when the drive member is running in the second direction to reach the docking position; when the docking hook is in the docking position, the elastic member is subjected to the pressure of the docking member and exerts a downward force on the frame.

[0008] The traction device for moving the warp threading machine's yarn frame according to an embodiment of the present invention has at least the following beneficial effects:

[0009] In use, the traction device for moving the warp threading machine's yarn frame of the present invention allows the drive member to pre-run along a first direction to drive the docking hook located at the docking position to swing downwards to an avoidance position. Then, the drive member drives the traction device and / or the yarn frame to move the warp threading machine's yarn frame, so that the docking shaft on the yarn frame is above the docking hook. Then, the drive member runs along a second direction to cause the elastic member to drive the docking hook to swing upwards to reach the docking position, thereby hooking the docking shaft on the yarn frame and achieving docking between the yarn frame and the traction device for moving the warp threading machine's yarn frame. Afterwards, the drive wheel can drive the traction device for moving the warp threading machine's yarn frame to move, thereby moving the yarn frame.

[0010] In the traction device for moving the yarn frame of the traction warping machine of the present invention, the docking mechanism is used to dock with the docking shaft of the yarn frame, which is convenient to operate and does not require the aid of ropes. Furthermore, after the docking mechanism and the docking shaft of the yarn frame are docked, the elastic element can still apply downward pressure to the frame, and this force can be transmitted to the drive wheel through the frame, thereby increasing the friction between the drive wheel and the ground, thereby reducing the risk of the drive wheel slipping and improving reliability.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] like Figure 1 As shown, an embodiment of the present invention relates to a traction device 10 for moving the yarn frame of a warping machine, which includes a frame 11, a drive wheel 12, and a docking mechanism 13.

[0049] The frame 11 is the main load-bearing component of the traction equipment 10.

[0050] The drive wheel 12 is mounted on the frame 11 and can drive the frame 11 and the components mounted on the frame 11 to move.

[0051] Specifically, the drive wheel 12 is located at the bottom of the frame 11. The drive wheel 12 is used to support the frame 11 above the ground and prevent the frame 11 from being worn by friction with the ground during the movement of the traction equipment 10.

[0052] The number of drive wheels 12 can be one or more.

[0053] Specifically, there are two drive wheels 12, which are spaced apart on the bottom of the frame 11, one on the left and one on the right.

[0054] Combination Figure 1 and Figure 2 The docking mechanism 13 is provided on the frame 11. The docking mechanism 13 is used to dock with the yarn frame 20, so that the yarn frame 20 is connected to the traction device 10, so that the traction device 10 can pull the yarn frame 20 to move.

[0055] Combination Figure 3 and Figure 4 The docking mechanism 13 includes a docking member 131 rotatably connected to the frame 11, a driving member 132 for driving the docking member 131 to rotate in a vertical plane, and an elastic member 133 disposed on the frame 11 and connected to the docking member 131. The front end of the docking member 131 has a docking hook 1311 that can rotate around the rotation center axis of the docking member 131.

[0056] Specifically, the docking member 131 is connected to a rotating shaft 1312, which passes through the frame 11 so that the docking member 131 can rotate relative to the frame 11 in a vertical plane. The driving member 132 can apply a force to the docking member 131 to drive the docking member 131 to rotate in the vertical plane. When the docking member 131 rotates in the vertical plane, the docking hook 1311 at the front end of the docking member 131 also rotates around the rotation center axis of the docking member 131.

[0057] Among them, the docking hook 1311 has an avoidance position and a docking position.

[0058] Specifically, when the docking hook 1311 in the docking position swings downward, it can reach the avoidance position; when the docking hook 1311 in the avoidance position swings upward, it can reach the docking position.

[0059] in, Figure 3 and Figure 4 The docking hook 1311 is in the docking position.

[0060] Understandably, when the docking hook 1311 is in the avoidance position, it can avoid the docking shaft 21 on the yarn frame 20 so that the docking shaft 21 can move above the docking hook 1311; when the docking hook 1311 is in the docking position, the docking hook 1311 can hook the docking shaft 21 of the yarn frame 20, so that the yarn frame 20 is connected to the traction device 10.

[0061] Furthermore, the docking hook 1311 located in the docking position can swing downward under the drive of the drive member 132 when the drive member 132 is running in the first direction to reach the avoidance position, and the docking hook 1311 located in the avoidance position can swing upward under the drive of the elastic member 133 when the drive member 132 is running in the second direction to reach the docking position.

[0062] Understandably, when the docking hook 1311 is in the docking position, the driving member 132 runs along the first direction, thereby driving the docking member 131 to rotate along the first rotation direction, so that the docking hook 1311 swings downward to the avoidance position; when the docking hook 1311 is in the avoidance position, the driving member 132 runs along the second direction opposite to the first direction and loses the effect of limiting the docking hook 1311 to the avoidance position, while the elastic member 133 gradually drives the docking member 131 to rotate along the second rotation direction opposite to the first rotation, so that the docking hook 1311 swings upward to the docking position.

[0063] It should be noted that during the process of the driving member 132 running along the first direction and driving the docking member 131 to rotate along the first rotation direction, causing the docking hook 1311 to swing downward, the elastic member 133 is slowly compressed and accumulates energy; when the driving member 132 runs along the second direction, the elastic member 133 slowly resets to drive the docking member 131 to rotate along the second rotation direction opposite to the first rotation, thereby causing the docking hook 1311 to swing upward.

[0064] Furthermore, when the docking hook 1311 is in the docking position, the elastic element 133 is subjected to the pressure of the docking element 131 and exerts a downward force on the frame 11.

[0065] Specifically, when the docking hook 1311 is in the docking position, the elastic element 133 is still subjected to pressure from the docking element 131, thereby exerting a downward force on the frame 11, which can be transmitted to the drive wheel 12 through the frame 11.

[0066] When the traction device 10 of the present invention is in use, the driving member 132 can run in advance along the first direction to drive the docking hook 1311 located at the docking position to swing downward to the avoidance position, and then drive the traction device 10 and / or the yarn frame 20 so that the docking shaft 21 on the yarn frame 20 is above the docking hook 1311. Then, the driving member 132 runs along the second direction so that the elastic member 133 drives the docking hook 1311 to swing upward to reach the docking position so as to hook the docking shaft 21 on the yarn frame 20, thereby realizing the docking of the yarn frame 20 and the traction device 10. After that, the driving wheel 12 can drive the traction device 10 to move, thereby moving the yarn frame 20.

[0067] In the traction device 10 of the present invention, the docking mechanism 13 is used to dock with the docking shaft 21 of the yarn frame 20, which is convenient to operate and does not require the aid of ropes. Furthermore, after the docking mechanism 13 and the docking shaft 21 of the yarn frame 20 are docked, the elastic element 133 can still apply downward pressure to the frame 11, and this force can be transmitted to the drive wheel 12 through the frame 11, thereby increasing the friction between the drive wheel 12 and the ground, thereby reducing the risk of the drive wheel 12 slipping and improving reliability.

[0068] Combination Figure 3 and Figure 4 In some embodiments, the bottom end of the elastic member 133 is connected to the frame 11, and the top end of the elastic member 133 is connected to the docking member 131; the vertical plane where the rotation center axis of the docking member 131 is located is defined as the reference plane, and the top end of the elastic member 133 and the docking hook 1311 are located on the same side of the reference plane.

[0069] Understandably, the top of the elastic element 133 and the docking hook 1311 are located on the same side of the reference plane. Thus, when the docking hook 1311 swings downward, the top of the elastic element 133 also swings downward so that the elastic element 133 is gradually compressed further. In this way, when the docking hook 1311 moves from the docking position to the avoidance position, the elastic element 133 can slowly accumulate energy so as to subsequently push the docking hook 1311 from the avoidance position to the docking position.

[0070] It should be noted that the elastic element 133 is in a compressed state whether the docking hook 1311 is in the docking position or the avoidance position. The compression of the elastic element 133 when the docking hook 1311 is in the avoidance position is greater than that when the docking hook 1311 is in the docking position.

[0071] Among them, the elastic element 133 can be a spring, such as a helical spring or a nitrogen spring.

[0072] Furthermore, the top end of the elastic member 133 is adjustablely connected to the mating member 131.

[0073] Specifically, the connection position between the top of the elastic element 133 and the docking element 131 can be adjusted up and down. By changing the connection position between the top of the elastic element 133 and the docking element 131, the pressure of the elastic element 133 on the frame 11 when the docking hook 1311 is in the docking position can be changed, thereby changing the pressure of the frame 11 on the drive wheel 12, thereby adjusting the magnitude of the friction between the drive wheel 12 and the ground, so that the traction device 10 can adapt to the traction of yarn frames 20 of different weights.

[0074] The docking member 131 is provided with a plurality of fixing parts 1313 arranged vertically, and the top end of the elastic member 133 is connected to a fixing block 1332, which can be selectively connected to the fixing part 1313.

[0075] Understandably, by choosing to connect the fixing block 1332 to different fixing parts 1313, the height of the top of the elastic element 133 can be changed.

[0076] Specifically, the fixing part 1313 is provided with a first mounting hole, and each fixing block 1332 is provided with a second mounting hole. By using a fastener to pass through the first mounting hole and the second mounting hole, the fixing block 1332 and the fixing part 1313 can be connected.

[0077] The fastener can be a screw. One of the first mounting hole and the second mounting hole is a screw hole, and the other is a through hole. The screw is inserted into the through hole and the screw hole in sequence.

[0078] Of course, in other embodiments, the fixing block 1332 and the fixing part 1313 can also be fixed by rivets or welding.

[0079] Combination Figure 3 and Figure 4 In one embodiment, the bottom of the elastic member 133 is connected to a limiting shaft 1331, which is rotatably mounted on the frame 11. The top of the elastic member 133 is rotatably connected to the fixing block 1332. Thus, when the docking member 131 rotates, the elastic member 133 will also deflect, avoiding interference between the elastic member 133 and the docking member 131.

[0080] Combination Figure 3 and Figure 4In some embodiments, the drive member 132 is rotatably connected to the frame 11. The drive member 132 has a telescopic shaft 1321 located behind the docking member 131. The telescopic shaft 1321 is horizontally arranged and perpendicular to the rotation center axis of the docking member 131. The telescopic shaft 1321 is connected to a connector 1322. The connector 1322 is provided with a transverse guide groove 13221. The extension direction of the transverse guide groove 13221 is the same as the axis of the telescopic shaft 1321. A connecting shaft 1314 is fixed on the docking member 131. The connecting shaft 1314 is parallel to the rotation center axis of the docking member 131 and located above the rotation center axis of the docking member 131. The connecting shaft 1314 passes through the transverse guide groove 13221.

[0081] When the drive member 132 runs in the first direction, the telescopic shaft 1321 extends out, and when the drive member 132 runs in the second direction, the telescopic shaft 1321 retracts.

[0082] Understandably, when the docking hook 1311 is in the docking position, the telescopic shaft 1321 extends and drives the docking member 131 to rotate in the first rotation direction, thereby causing the docking hook 1311 to swing downward to the avoidance position; when the docking hook 1311 is in the avoidance position, the telescopic shaft 1321 retracts and the elastic element 133 drives the docking member 131 to rotate in the second rotation direction, so that the docking hook 1311 swings upward to reach the docking position.

[0083] It should be noted that in the traction device 10 of the present invention, the elastic element 133, as a component for driving the docking hook 1311 to move from the avoidance position to the docking position, has at least the following beneficial effects:

[0084] First, if, when the docking shaft 21 of the yarn frame 20 and the docking piece 131 are docked, the docking shaft 21 of the yarn frame 20 is not located directly above the groove of the docking hook 1311, but directly above the tip of the docking hook 1311, during the process of the elastic member 133 driving the docking hook 1311 to move from the avoidance position to the docking position, the tip of the docking hook 1311 will abut against the docking shaft 21 of the yarn frame 20 and be prevented from continuing to swing upward. At this time, the elastic member 133 cannot continue to reset. At this time, the elastic member 133 exerts greater pressure on the frame 11, thereby increasing the friction force on the drive wheel 12, which can reduce the risk of the yarn frame 20 pushing the traction device 10 to move.

[0085] Second, the elastic element 133 drives the docking element 131 in a flexible manner. That is, if the top tip of the docking hook 1311 abuts against the docking shaft 21 of the yarn frame 20, the elastic element 133 will not forcefully push the docking hook 1311 to continue moving towards the docking position, which can reduce the risk of the docking hook 1311 and the docking shaft 21 being damaged by the interaction force.

[0086] Combination Figure 3 and Figure 4 In some embodiments, a mounting base 135 is provided on the frame 11, and the drive component 132 is rotatably connected to the mounting base 135. In this way, when the telescopic shaft 1321 extends or retracts, interference between the connecting component 1322 and the connecting shaft 1314 can be avoided.

[0087] In some embodiments, the docking member 131 is provided with an arc-shaped guide groove 1315, which is coaxially arranged with the rotation center axis of the docking member 131. A guide shaft 134 passing through the arc-shaped guide groove 1315 is provided on the frame 11, thereby further improving the stability of the docking member 131 during rotation.

[0088] like Figure 1 As shown, in some embodiments, there are two drive wheels 12, which are arranged side by side, one on the left and one on the right.

[0089] Specifically, one drive wheel 12 is located below the left side of the frame 11, and the other drive wheel 12 is located below the right side of the frame 11. This improves the stability of the traction device 10 during operation.

[0090] Furthermore, the traction device 10 also includes a steering mechanism 14 mounted on the frame 11. The steering mechanism 14 is used to drive the two drive wheels 12 to change direction, thereby causing the traction device 10 to change its travel direction.

[0091] like Figure 5 , Figure 6 and Figure 9 As shown, the steering mechanism 14 includes a handle 141, a drive sprocket 142, a driven sprocket 143, a first chain 144, a second chain 145, and a third chain 146.

[0092] First, it should be noted that among the two drive wheels 12, one drive wheel 12 is the first drive wheel 121 and the other drive wheel 12 is the second drive wheel 122. The first drive wheel 121 is fixedly equipped with a first sprocket 1211 and the second drive wheel 122 is fixedly equipped with a second sprocket 1221.

[0093] A handle 141 is rotatably mounted on the frame 11 and can rotate. A drive sprocket 142 is connected to the handle 141 and located behind the first sprocket 1211. Rotating the handle 141 can drive the drive sprocket 142 to rotate. A driven sprocket 143 is rotatably mounted on the frame 11 and located behind the second sprocket 1221. The two ends of the first chain 144 are respectively fitted onto the drive sprocket 142 and the driven sprocket 143, and the first chain 144 is arranged in an "8" shape. The two ends of the second chain 145 are respectively fitted onto the drive sprocket 142 and the first sprocket 1211, and the second chain 145 is not arranged in an "8" shape. The two ends of the third chain 146 are respectively fitted onto the driven sprocket 143 and the second sprocket 1221, and the third chain 146 is not arranged in an "8" shape.

[0094] It is understandable that when the handle 141 is turned, the first drive wheel 121 and the second drive wheel 122 can be turned by the coordinated action of the various components.

[0095] Furthermore, the handle 141 has a transmission rod 1411, and the drive sprocket 142 is fixedly sleeved on the transmission rod 1411. Thus, when the handle 141 is turned, the transmission rod 1411 rotates accordingly, thereby driving the drive sprocket 142 to rotate, thereby causing the first drive wheel 121 and the second drive wheel 122 to turn.

[0096] like Figure 9 , Figure 10 As shown, in some embodiments, the steering mechanism 14 further includes a mounting bracket 147 disposed on the frame 11. The mounting bracket 147 is provided with a first sensor 1473 and a second sensor 1474 spaced apart in the horizontal direction. Both the first sensor 1473 and the second sensor 1474 are electrically connected to the two drive wheels 12. A transmission rod 1411 is rotatably disposed through the mounting bracket 147 and is located between the first sensor 1473 and the second sensor 1474. A sensing plate 14111 is disposed on the transmission rod 1411. The sensing plate 14111 can sense each other with the first sensor 1473 or the second sensor 1474 as the transmission rod 1411 rotates.

[0097] In some embodiments, the first sensor 1473 and the second sensor 1474 can both be limit switches, and the first sensor 1473 and the second sensor 1474 are located on the rotation path of the sensing sheet 14111.

[0098] like Figures 6 to 10As shown, it can be understood that when the handle 141 is turned, the transmission rod 1411 drives the sensing plate 14111 to rotate. When the sensing plate 14111 is only in contact with the first sensor 1473, the first drive wheel 121 and the second drive wheel 122 are energized and can move forward or backward simultaneously. For example, when the first drive wheel 121 moves forward, the second drive wheel 122 also moves forward. At this time, the traction device 10 can perform linear or directional movement. When the sensing plate 14111 is not in contact with the first sensor 1473 or the second sensor 1474, the first drive wheel 121 and the second drive wheel 122 are not energized, and the traction device 10 cannot move. When the sensing plate 14111 is exactly in contact with the second sensor 1474, one of the drive wheels 12 rotates in the opposite direction.

[0099] Specifically, when the handle 141 is removed from... Figure 6 Position rotated to Figure 8 During the positioning process, initially, the sensing element 14111 only contacts the first sensor 1473. At this time, the first drive wheel 121 and the second drive wheel 122 are energized and move forward simultaneously. As the handle 141 rotates clockwise, the sensing element 14111 remains in contact with the first sensor 1473. When the handle 141 rotates to... Figure 8 When in position, the handle 141 is in contact with the second sensor 1474, and the second drive wheel 122 rotates in the opposite direction. At this time, the first drive wheel 121 and the second drive wheel 122 move in the same direction, thereby enabling the traction device 10 to move forward.

[0100] In some other embodiments, the first sensor 1473 and the second sensor 1474 can both be photoelectric sensors. The sensing sheet 14111 only needs to be sensed by the first sensor 1473 or the second sensor 1474 to control the first drive wheel 121 and the second drive wheel 122.

[0101] Specifically, the first sensor 1473 and the second sensor 1474 are arranged horizontally at intervals, and both the first sensor 1473 and the second sensor 1474 emit light upwards. When the sensing plate 14111 rotates only above the first sensor 1473 and blocks the light emitted by the first sensor 1473, the first drive wheel 121 and the second drive wheel 122 are energized and can move simultaneously in front of or behind each other. When the light emitted by the first sensor 1473 and the second sensor 1474 is not blocked by the sensing plate 14111, the first drive wheel 121 and the second drive wheel 122 are not energized, and the traction device 10 cannot move. When the sensing plate 14111 rotates exactly above the second sensor 1474 and blocks the light emitted by the second sensor 1474, one of the drive wheels 12 rotates in the opposite direction.

[0102] like Figure 10 As shown, the mounting bracket 147 is further provided with a first limiting post 1471 and a second limiting post 1472 spaced apart in the horizontal direction. The transmission rod 1411 is located between the first limiting post 1471 and the second limiting post 1472. The transmission rod 1411 is provided with a limiting part 14112. The first limiting post 1471 and the second limiting post 1472 are located on the rotation path of the limiting part 14112.

[0103] Specifically, the first limiting post 1471 and the second limiting post 1472 are used to limit the rotation angle of the transmission rod 1411. When the handle 141 is rotated to... Figure 8 When in position, the limiting part 14112 is exactly against the first limiting post 1471.

[0104] In some embodiments, the handle 141 is provided with a control button for controlling the drive unit to run in a first direction or in a second direction.

[0105] like Figure 1 As shown, in some embodiments, the bottom of the frame 11 is provided with auxiliary wheels 15, which are omnidirectional wheels, to improve the stability of the traction device 10 during the forming process.

[0106] When the traction device 10 of the present invention is in use, the driving member 132 can run in advance along the first direction to drive the docking hook 1311 located at the docking position to swing downward to the avoidance position, and then drive the traction device 10 and / or the yarn frame 20 so that the docking shaft 21 on the yarn frame 20 is above the docking hook 1311. Then, the driving member 132 runs along the second direction so that the elastic member 133 drives the docking hook 1311 to swing upward to reach the docking position so as to hook the docking shaft 21 on the yarn frame 20, thereby realizing the docking of the yarn frame 20 and the traction device 10. After that, the driving wheel 12 can drive the traction device 10 to move, thereby moving the yarn frame 20.

[0107] In the traction device 10 of the present invention, the docking mechanism 13 is used to dock with the docking shaft 21 of the yarn frame 20, which is convenient to operate and does not require the aid of ropes. Furthermore, after the docking mechanism 13 and the docking shaft 21 of the yarn frame 20 are docked, the elastic element 133 can still apply downward pressure to the frame 11, and this force can be transmitted to the drive wheel 12 through the frame 11, thereby increasing the friction between the drive wheel 12 and the ground, thereby reducing the risk of the drive wheel 12 slipping and improving reliability.
