Detailed Implementation

[0040] The core of this invention is to disclose an automatic fabric feeding and shaft changing device to improve the efficiency of the fabric feeding process of a loom.

[0041] like Figures 1-8 As shown, the automatic fabric dropping and shaft changing device provided in this embodiment of the invention includes a fabric dropping unit 10, a shaft changing unit 20, a fabric cutting unit 30, and a rewinding unit 40, wherein, as... Figure 1 , Figure 2 and Figure 3As shown, the cloth falling unit 10 is used to roll the cloth 50 into a roll to realize the cloth falling of the cloth 50, and specifically, the cloth falling unit 10 comprises a frame body 110, a cloth roller 120 for rolling the cloth 50 is arranged on the frame body 110, the cloth roller 120 is rotationally arranged on the frame body 110, the cloth roller 120 is drivingly connected with a first driving device, the first driving device drives the cloth roller 120 to rotate, so that the cloth 50 is wound on the cloth roller 120 and then the cloth 50 is driven to fall by the rotation of the cloth roller 120.

[0042] It should be noted that the cloth roller 120 is arranged at the cloth falling position, and the cloth 50 needs to be wound on the cloth roller 120 in advance before the cloth roller 120 rotates, and this process can be performed manually or by the continuous rolling unit 40 provided in the embodiment of the present application to pre-roll the cloth 50.

[0043] The shaft changing unit 20 is used to push the cloth roller 120 away from the cloth falling position and drive another cloth roller 120 to move to the cloth falling position, that is, when the cloth roller 120 completes the rolling of the cloth 50 at the cloth falling position, the cloth roller 120 needs to be pushed out for collection, and the cloth falling position needs to be emptied to provide space for the placement of the subsequent cloth roller 120. The shaft changing unit 20 pushes the cloth roller 120 away from the cloth falling position after the cloth roller 120 completes the cloth rolling, so as to collect the cloth roller 120 after the cloth rolling, and the shaft changing unit 20 drives another cloth roller 120 which has not been rolled to move to the cloth falling position to perform the next cloth rolling action.

[0044] It should be noted that the standard for judging that a single cloth roller 120 completes the cloth rolling action can be the length of the cloth 50 falling or the number of rotations of the cloth roller 120. In a specific embodiment of the present application, a meter value of the cloth 50 rolled by a single cloth roller 120 is set in advance in the controller, and the controller controls the shaft changing unit 20 to act to push the cloth roller 120 away from the cloth falling position when the meter value of the cloth 50 falling reaches the set value.

[0045] On the basis of the above embodiment, after the shaft changing unit 20 pushes the cloth roller 120 away from the cloth falling position after the cloth rolling is completed, the cloth 50 wound on the cloth roller 120 is cut by the cloth cutting unit 30, and the cutting path of the cloth cutting unit 30 passes through the downstream of the cloth falling position, so that the cloth roller 120 and the cloth 50 are cut and separated after the cloth roller 120 leaves the cloth falling position, so that the cloth roller 120 after the cloth rolling can be collected and loaded, and the cloth 50 is cut to perform the subsequent cloth rolling action.

[0046] Further, the cut-off cloth 50 can be manually rolled into the cloth roller 120 newly placed at the cloth dropping position when the subsequent cloth rolling action is performed, or the subsequent cloth rolling pre-treatment can be realized by the continuous rolling unit 40 provided in the embodiment of the present application. In a specific embodiment of the present application, the continuous rolling unit 40 is arranged at the periphery of the cloth dropping position, and is used to roll the cloth head formed after the cloth 50 is cut off into the cloth surface of the cloth 50 and the cloth roller 120 at the cloth dropping position after the cloth roller 120 without cloth is driven to the cloth dropping position by the shaft changing unit 20, so that the cloth roller 120 at the cloth dropping position can be rotated to perform the subsequent cloth rolling action.

[0047] The automatic cloth dropping and shaft changing device provided in the embodiment of the present application has a working cycle of one period, in which the cloth roller 120 at the cloth dropping position in the cloth dropping unit 10 is rotated to roll the cloth 50, the cloth roller 120 after the cloth 50 is rolled to the required length is pushed away from the cloth dropping position by the shaft changing unit 20, and the cloth roller 120 after the cloth 50 is rolled is cut off from the cloth 50 by the cloth cutting unit 30, so that the cloth roller 120 is separated for collection, and another cloth roller 120 without cloth is driven to the cloth dropping position by the shaft changing unit 20, and the cloth head of the cloth 50 at the cutting position is driven to the cloth surface of the cloth 50 and the cloth roller 120 at the cloth dropping position by the continuous rolling unit 40, so that the cloth 50 is pre-rolled by the rotation of the cloth roller 120, and one working cycle of the cloth dropping is completed, and the next working cycle is automatically performed.

[0048] The automatic cloth falling and shaft replacing device provided by the embodiment of the application is provided with a frame body 110, a cloth roller 120 and a first driving device in a cloth falling unit 10, so that the cloth roller 120 is driven to rotate by the first driving device. When the rolling of the cloth 50 is needed, only the cloth head of the cloth 50 needs to be rolled between the cloth surface of the cloth 50 and the cloth roller 120, and the first driving device is started, so that the cloth roller 120 can roll the cloth 50. Here, the cloth roller 120 is arranged at the cloth falling position. Further, after the single cloth roller 120 completes the rolling of the cloth 50 at the cloth falling position, the cloth roller 120 after the rolling of the cloth 50 is pushed away from the cloth falling position by the shaft replacing unit 20. After the cloth roller 120 after the rolling of the cloth 50 is pushed away from the cloth falling position, on the one hand, the subsequent cloth cutting action of the cloth roller 120 is facilitated, and on the other hand, a new cloth roller 120 that has not been rolled can be arranged at the cloth falling position to perform a new rolling action. In order to improve the efficiency of the cloth falling process and optimize the process of manual cloth cutting in the prior art, the cutting path of the cloth cutting unit 30 is arranged downstream of the cloth falling position, so that the cloth roller 120 and the cloth 50 are cut and separated by the cloth cutting unit 30 after the cloth roller 120 after the rolling of the cloth 50 is pushed away from the cloth falling position by the shaft replacing unit 20, so as to collect and load the cloth roller 120. At the same time, in order to roll the cloth head after the cloth 50 is cut into the cloth roller 120 arranged at the cloth falling position, the cloth head after the cloth 50 is cut is driven by the continuous rolling unit 40 arranged around the cloth falling position, so as to roll the cloth head into the cloth surface of the cloth 50 and the cloth roller 120 arranged at the cloth falling position. The above process can be automatically operated by the automatic cloth falling and shaft replacing device provided by the application, and only a new cloth roller 120 needs to be manually or automatically arranged, so that the rolling action can be periodically and automatically completed, and the action process does not need to be manually controlled, so that the loom can be automatically operated at any time, and the efficiency of the cloth falling process of the loom is effectively improved.

[0049] Further, as Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in the automatic cloth changing shaft device provided by the embodiment of the present application, the functional components of the changing shaft unit 20 include a transmission shaft 210, a linkage disc 220, a C-shaped cover 230, a traction disc 240, a swing block 250 and a U-shaped rail 260. It should be noted that, unless otherwise specified, the structural components provided by the embodiment of the present application are all left-right symmetrical structural components. For the convenience of description, only the unilateral structural components are described in detail herein. Specifically, the transmission shaft 210 is a power input component and is in transmission connection with the linkage disc 220. The linkage disc 220 is provided with a fixing hole 2210, and the linkage disc 220 is fixedly arranged by a pin shaft penetrating through the fixing hole 2210. The transmission shaft 210 is in transmission connection with the linkage disc 220 to drive the linkage disc 220 to move reversely with respect to the transmission shaft 210. It should be noted that, the reverse movement herein refers to the reverse rotation direction of the linkage disc 220 with respect to the transmission shaft 210. For example, when the transmission shaft 210 rotates clockwise, the linkage disc 220 rotates counterclockwise. The transmission mode of the reverse movement can be realized by gear transmission or by linkage structure transmission.

[0050] On this basis, the linkage disc 220 is a second power component driven by the transmission shaft 210 to drive other components to move. The C-shaped cover 230 is provided with a connecting hole, and the C-shaped cover 230 is arranged on the frame body 110 by a pin shaft penetrating through the connecting hole. The C-shaped cover 230 is in transmission connection with the linkage disc 220 and synchronously moves reversely with the linkage disc 220. It should be noted that, the reverse movement herein refers to the reverse rotation direction of the linkage disc 220 with respect to the C-shaped cover 230. For example, when the linkage disc 220 rotates clockwise, the C-shaped cover 230 rotates counterclockwise. The C-shaped cover 230 is used to push the cloth roller 120 away from the cloth falling position in the process of being driven by the linkage disc 220. Specifically, the C-shaped cover 230 is provided with a roller 2310, which contacts the shaft head position of the central shaft of the cloth roller 120 when the cloth roller 120 performs the cloth winding action. After the cloth winding of the cloth roller 120 is completed, the roller 2310 is driven by the rotation of the C-shaped cover 230 to push the cloth roller 120, so that the cloth roller 120 moves away from the cloth falling position.

[0051] The other component driven by the linkage disc 220 is the traction disc 240. Similarly, the traction disc 240 is in transmission connection with the linkage disc 220 and synchronously performs reverse motion with the linkage disc 220. It should be noted that the reverse motion herein refers to the reverse rotation direction of the linkage disc 220 and the traction disc 240. For example, when the linkage disc 220 rotates clockwise, the traction disc 240 rotates counterclockwise. The swing block 250 is arranged on the traction disc 240 and can drive the swing block 250 to contact or move away from the U-shaped rail 260 during the rotation of the traction disc 240 driven by the linkage disc 220. It should be noted that one end of the U-shaped rail 260 is used to contact the swing block 250, and the other end is located at the cloth falling position. The track of the U-shaped rail 260 can be used to clamp the shaft head of the two ends of the shaft of the cloth roller 120, so that the cloth roller 120 can slide along the track of the U-shaped rail 260. When the swing block 250 contacts the U-shaped rail 260, the swing block 250 and the U-shaped rail 260 form a placing space for placing the cloth roller 120. That is, the swing block 250 can be used to pre-place the cloth roller 120 without winding cloth at the position of the swing block 250 when the swing block 250 contacts the U-shaped rail 260. After the cloth roller 120 at the cloth falling position is pushed away from the cloth falling position by the roller 2310, the swing block 250 is driven by the traction disc 240 to move away from the U-shaped rail 260, so that the new cloth roller 120 without winding cloth slides along the U-shaped rail 260 to the cloth falling position.

[0052] It should be noted that only the linkage disc 220 is used to drive the C-shaped cover 230 and the traction disc 240 to push away, clamp and release the sliding action of the cloth roller 120, which can simplify the structure of the automatic cloth falling and shaft replacing device provided by the embodiment of the application, so that the automatic cloth falling and shaft replacing device provided by the embodiment of the application is easy to install and maintain. Since the C-shaped cover 230 and the traction disc 240 are driven by a single linkage disc 220, the swing block 250 is driven by the traction disc 240 to contact the U-shaped rail 260 when the C-shaped cover 230 pushes away the cloth roller 120 at the cloth falling position. After the C-shaped cover 230 completes the pushing away of the cloth roller 120, the swing block 250 is driven by the traction disc 240 to move away from the U-shaped rail 260, so that the new cloth roller 120 slides to the cloth falling position.

[0053] To further optimize the above technical solutions, in an embodiment of the present application, the transmission shaft 210 is drivingly connected to the driving arm 270, the driving arm 270 and the connecting rod 280 and the linkage disc 220 form a crank rocker mechanism, so that the transmission shaft 210 drives the linkage disc 220 to move, specifically, the transmission shaft 210 transmits power to the driving arm 270, the driving arm 270 is hingedly connected to the connecting rod 280, the connecting rod 280 is hingedly connected to the first hinged point 2220 of the linkage disc 220, so that when the transmission shaft 210 rotates counterclockwise, the driving arm 270 swings counterclockwise, the connecting rod 280 swings counterclockwise, and because the first hinged point 2220 of the linkage disc 220 is closer to the driving arm 270 than the fixed hole 2210 of the linkage disc 220, the linkage disc 220 rotates clockwise, so as to realize the purpose that the transmission shaft 210 drives the linkage disc 220 to move in the opposite direction.

[0054] Further, in an embodiment of the present application, the linkage disc 220 drives the C-shaped cover 230 to move in the opposite direction through the short rod 290, one end of the short rod 290 is hingedly connected to the second hinged point 2230 of the linkage disc 220, the other end is hingedly connected to the C-shaped cover 230, when the linkage disc 220 rotates clockwise, the short rod 290 and the end hingedly connected to the second hinged point rotate counterclockwise through the second hinged point 2230, because the short rod 290 is arranged between the linkage disc 220 and the C-shaped cover 230, the C-shaped cover 230 rotates counterclockwise under the driving of the short rod 290, thereby realizing the purpose that the linkage disc 220 drives the C-shaped cover 230 to move in the opposite direction through the short rod 290.

[0055] To ensure the stability of the cloth roller 120 when rolling cloth at the cloth falling position, and avoid the cloth roller 120 from sliding, the embodiment of the present application is provided with the claw 2320 on the C-shaped cover 230, during the cloth rolling process of the cloth roller 120, the claw 2320 is used to cooperate with the roller 2310 to clamp the end shaft of the cloth roller 120.
