Description

Technical Field

[0001] The invention relates to the field of spinning frames, and in particular to an integrated doffing device for a spinning frame. Background Art

[0002] Spinning frame is a spinning machine that stretches, twists and winds semi-finished roving or sliver into spun yarn in the spinning process. The sliver is stretched and twisted on the roving frame to make roving, the combing machine combs the fiber to make combed sliver, the gill combing machine combines the slivers, and the pin row stretching improves the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame. The spinning frame is the main machine for spinning. The output and quality of spun yarn are a comprehensive reflection of the quality of each process of the spinning process.

[0003] The collective doffing device is a device that automatically removes all full bobbins from the spinning frame and replaces them with empty bobbins and starts the yarn. It is a fully automatic doffing device that generally uses a combination of electrical, mechanical and pneumatic methods to complete all doffing actions, including yarn pulling, tube insertion and tube feeding. Yarn pulling and tube insertion are mainly completed by the yarn holding cup installed on the crossbeam that runs through the entire machine.

[0004] After the yarn is finally spun into fine yarn, the doffer needs to wind the fine yarn on the yarn tube for easy storage and transportation. In traditional work, in the existing doffer device of the doffer, the yarn tubes of an entire production line are removed and replaced by the machine at one time, which greatly reduces the manual labor and improves the efficiency. However, there is still a certain inefficiency when changing the tube. The doffer can only control one group of yarn tubes at a time. In this way, when changing the tube, the already wound yarn tube needs to be removed first, placed on the transport track, and then a cycle is performed to clamp the empty yarn tube and place it in the working position. During this period, the spinning frame has been in a shutdown state, wasting time.

[0005] Therefore, it is necessary to provide an integrated doffing device for a spinning frame to solve the above technical problems. Summary of the invention

[0006] The present invention provides an integrated doffing device for a spinning frame, which solves the problem that the doffing machine can only control one group of yarn tubes at a time. Thus, when changing the tubes, it is necessary to first take down the wound yarn tubes, place them on a transport track, and then perform another cycle to pick up the empty yarn tubes and place them in the working position. During this period, the spinning frame is always in a shutdown state, wasting time.

[0007] In order to solve the above technical problems, the present invention provides an integrated doffing device for a spinning frame, comprising: a doffing frame;

[0018] Preferably, a control box is fixedly mounted on one side of the outer surface of the doffing frame.

[0019] The bobbin with the wound wire is restricted by the sleeve device and the limit device. As the movable frame moves upward, the pushing device moves to the front side. Then the movable frame is controlled to move downward and the pushing device moves backward, so that the sleeve device places the bobbin with the wound wire on the conveying line. Then the pushing device moves upward and forward with the movable frame, so that the sleeve device is separated from the bobbin with the wound wire. Then the driving device is controlled to drive the connecting device to move to the right by the distance of one bobbin. The movable frame moves downward and the pushing device moves backward to clamp the empty bobbin and work again.

[0020] Preferably, a clamping device is fixedly mounted on one side of the outer surface of the clamping block, and the clamping device comprises a wear-resistant pad, and a protrusion is fixedly connected to the surface of the wear-resistant pad.

[0021] Preferably, the wear-resistant pad and the bump are both made of rubber.

[0022] By arranging a wear-resistant pad made of rubber material on the surface of the clamping block, when the clamping block approaches the surface of the tube, the friction force of the rubber is used to clamp the tube. The device has a simple structure and strong practicality. When clamping, it is not easy to deform the wire tube clamp while enhancing the friction force of clamping, thereby improving the safety of clamping.

The device has a simple structure and is highly practical. The sleeve device moves left and right to clamp the yarn tube, so that the yarn tube placed on the surface of the conveying production line can be clamped twice. First, the wound yarn tube is taken down and placed on the conveying production line. The sleeve device moves sideways to clamp the unwound yarn tube on the side and place it on the yarn winding production line for winding. During this period, the conveying production line can send away the wound yarn tube and replace it with a new yarn winding tube. The doffing machine does not need to stop and wait, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] At the same time, the output shaft of the second telescopic cylinder 6 is controlled by an external power supply to move forward, and the connecting plate 51 is pushed forward, so that the empty tube moves upward to the top front side of the yarn winding production line 12, and the output shafts of the first telescopic cylinder 3 and the second telescopic cylinder 6 are controlled by an external power supply to move in the opposite direction, so that the sleeve device 15 sleeves the empty tube on the surface of the yarn winding production line 12, and the output shaft of the double-head telescopic cylinder 161 is controlled by an external power supply to move in the opposite direction, and the block 163 releases the empty tube, and the empty tube is placed on the surface of the yarn winding production line 12 for winding.

[0053] The bobbin with the wound wire is restricted by the sleeve device 15 and the limit device 16. As the movable frame 4 moves upward, the pushing device 53 moves to the front side. Then the movable frame 4 is controlled to move downward and the pushing device 53 moves backward, so that the sleeve device 15 places the bobbin with the wound wire on the conveying production line 11. Then the pushing device 53 moves upward and forward with the movable frame 4, so that the sleeve device 15 is separated from the bobbin with the wound wire. Then the driving device 10 is controlled to drive the connecting device 5 to move to the right by the distance of one bobbin. The movable frame 4 moves downward and the pushing device 53 moves backward to clamp the empty bobbin and work again.

[0054] Compared with the related art, the integrated doffing device of the spinning frame provided by the present invention has the following beneficial effects:

The output shaft of a servo motor 101 is controlled by an external power supply to rotate, driving the threaded rod 102 to rotate and the meshing pushing device 53 to slide left and right on the surface of the limit rod 103, so that the sleeve device 15 can move left and right to clamp or place the yarn tube on the surface of the conveying production line 11. The device has a simple structure and strong practicality. The sleeve device 15 moves left and right to clamp the yarn tube, so that the yarn tube placed on the surface of the conveying production line 11 can be clamped twice. The wound yarn tube is first taken down and placed on the conveying production line. The sleeve device 15 moves to the side, and the unwound yarn tube on the side is clamped and placed on the yarn winding production line 12 for winding. During this period, the conveying production line 11 can send away the wound yarn tube and replace it with a new yarn winding tube.
