Description

Technical Field

[0001] This invention relates to a reversing mechanism and a reversing method, specifically, to a full-bore reversing mechanism and a reversing method. Background Technology

[0002] Currently, the removal of full-filament bobbins processed on the false twisting machine is entirely manual. After being removed from the machine, the bobbins are placed onto the yarn trolley according to a prescribed orientation. During this process, because the removal direction is fixed but the placement direction differs between left and right, the bobbins must be reversed before being placed onto the trolley. Currently, this can only be done manually, involving both handling and judgment. Because full-filament bobbins are heavy, the labor intensity for workers is high, and long working hours reduce their efficiency, making it impossible to meet production needs.

[0028] The diagram includes: base 1, rotating mechanism 2, flipping mechanism 3, first power source 21, rotating table 22, first spool bracket 31, first support frame 32, pin 33, connecting rod 34, drive motor 35, lead screw 36, lead screw nut 37, connecting shaft 38, second spool bracket 39, second support frame 40, front limit flipping detector 41, origin position flipping detector 42, rear limit flipping detector 43, left limit rotation detector 51, origin position rotation detector 52, and right limit rotation detector 53. Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 3 As shown, an embodiment of the present invention provides a full-bore spool reversing mechanism, comprising a support, a base 1, a rotating mechanism 2 containing a rotating table, and a flipping mechanism 3. The rotating mechanism 2 is fixedly connected to the support; the base 1 is located above the rotating mechanism 2 and is fixedly connected to the rotating table; the flipping mechanism 3 is fixedly connected to the base 1.

[0031] In the above embodiment, when the full yarn spool is located on the flipping mechanism 3 and the rotating mechanism 2 rotates, it drives the base 1 located on the rotating platform to rotate. The flipping mechanism 3 and the base 1 are fixedly connected. When the base 1 rotates, it drives the flipping mechanism 3 to rotate. The rotating mechanism 2 is used to drive the base 1 and the flipping mechanism 3 to rotate. Due to process requirements, the full yarn spool needs to be reversed. This embodiment uses the rotating mechanism 2 to reverse the full yarn spool. This embodiment has a simple and compact structure and high working efficiency.

[0032] Preferably, the rotating mechanism 2 includes a first power source and a rotating platform, the first power source driving the rotating platform to rotate. The first power source driving the rotating platform to rotate, thereby driving the tilting mechanism 3 located on the rotating platform to rotate. The first power source can be an existing component, such as an electric cylinder, a pneumatic cylinder, etc.

[0033] Preferably, the flipping mechanism 3 includes a second power source, a first yarn spool bracket 31, a second yarn spool bracket 39, a first support frame 32, and a second support frame 40. The first support frame 32 and the second support frame 40 are respectively fixedly connected to the base 1. The first yarn spool bracket 31 and the first support frame 32 are rotatably connected, and the second yarn spool bracket 39 and the second support frame 40 are rotatably connected. The first yarn spool bracket 31 and the second yarn spool bracket 39 are arranged opposite to each other, and the first yarn spool bracket 31 and the second yarn spool bracket 39 are connected by a connecting shaft 38. The second power source drives the first yarn spool bracket 31 and the second yarn spool bracket 39 to flip.

[0034] During operation, the bottom surfaces of both ends of the full yarn spool rest on the first yarn spool bracket 31 and the second yarn spool bracket 39. When the second power source is activated, it drives the first yarn spool bracket 31 and the second yarn spool bracket 39 to rotate. Since the first support frame 32 and the second support frame 40 are fixedly connected to the base 1, the first yarn spool bracket 31 and the first support frame 32 are rotatably connected, and the second yarn spool bracket 39 and the second support frame 40 are rotatably connected, and the first yarn spool bracket 31 and the second yarn spool bracket 39 are connected by a connecting shaft 38, the second power source can drive the first yarn spool bracket 31 and the second yarn spool bracket 39 to rotate synchronously. When the first yarn spool bracket 31 and the second yarn spool bracket 39 rotate, the full yarn spool located on them also rotates, rolls out of the first yarn spool bracket 31 and the second yarn spool bracket 39, and enters the next working position.

[0035] Preferably, the second power source includes a drive motor 35, a lead screw 36, a lead screw nut 37, and a connecting rod 34. The rotating shaft of the drive motor 35 is fixedly connected to the lead screw 36, and the lead screw nut 37 is fitted onto the lead screw 36. One end of the connecting rod 34 is rotatably connected to the lead screw nut 37, and the other end is fitted onto a connecting shaft 38. When the drive motor 35 is started, it drives the lead screw 36 to rotate, and the lead screw nut 37 on the lead screw 36 moves linearly along the lead screw 36. One end of the connecting rod 34 is connected to the lead screw nut 37, so the connecting rod 34 moves with the lead screw nut 37. The other end of the connecting rod 34 is fitted onto the connecting shaft 38, and there is a gap between them. The connecting rod 34 drives the connecting shaft 38 to rotate. The connecting shaft 38 rotates around the connection point of the first spool bracket 31 and the first support frame 32, and the connection point of the second spool bracket 39 and the second support frame 40. Since the connecting shaft 38 connects the first spool bracket 31 and the second spool bracket 39, when the connecting shaft 38 rotates, it also drives the first spool bracket 31 to rotate around the connection point between the first spool bracket 31 and the first support frame 32, and the second spool bracket 39 to rotate around the connection point between the second spool bracket 39 and the second support frame 40.

[0036] Preferably, the second power source further includes a pin 33, through which the connecting rod 34 and the connecting shaft 38 are connected. One end of the pin 33 is fitted onto the connecting shaft 38 with a clearance fit, and the other end of the pin 33 is rotatably connected to the connecting rod 34. To avoid interference between the components, the second power source also includes a pin 33. When the lead screw nut 37 and the connecting shaft 38 are misaligned, directly connecting the connecting rod 34 between the connecting shaft 38 and the lead screw nut 37 is difficult and may cause positional interference. In this preferred embodiment, by adding a pin 33, interference is avoided when connecting the connecting shaft 38 and the lead screw nut 37. One end of the pin 33 is fitted onto the connecting shaft 38 with a clearance fit, and the other end of the pin 33 is rotatably connected to one end of the connecting rod 34, while the other end of the connecting rod 34 is rotatably connected to the lead screw nut 37.

[0037] The flipping mechanism 3 flips during operation. Once the full-bore yarn rolls out of the flipping mechanism 3, the flipping mechanism 3 stops flipping. If the flipping mechanism 3 continues to flip after the full-bore yarn rolls out, it is meaningless and may cause positional interference. Preferably, the full-bore yarn reversing mechanism also includes a flipping detection device. The flipping detection device includes a front limit flipping detector 41, an origin point flipping detector 42, and a rear limit flipping detector 43, which are fixedly connected to the base 1. The front limit flipping detector 41 detects the extreme position of the flipping mechanism's forward flipping, the origin point flipping detector 42 detects the initial position where the flipping mechanism has not flipped, and the rear limit flipping detector 43 detects the extreme position of the flipping mechanism's backward flipping. The front limit flipping detector 41 may or may not be located at the extreme position of the flipping mechanism's forward flipping, as long as it can detect whether the flipping mechanism is at the extreme position of forward flipping. The rear limit flip detector 43 can be located at the extreme position of the flip mechanism's backward flipping, or it can be located elsewhere, as long as it can detect whether the flip mechanism is at the extreme position of backward flipping. The origin position flip detector 42 can be located at the initial position when the flip mechanism is not flipping, or it can be located elsewhere, as long as it can detect whether the flip mechanism is at the initial position when it is not flipping. By setting the front limit flip detector 41, the origin position flip detector 42, and the rear limit flip detector 43, the flip mechanism 3 stops flipping when it is at the extreme position of forward flipping, the initial position when it is not flipping, or the extreme position of backward flipping.

[0038] The rotating mechanism 2 rotates during operation. When the full-bore yarn changes direction with the rotating mechanism 2, the rotating mechanism 2 stops rotating. To accurately control the rotation angle of the rotating mechanism 2, preferably, the full-bore yarn reversing mechanism also includes a rotation detection device. The rotation detection device includes a left limit rotation detector 51, an origin point rotation detector 52, and a right limit rotation detector 53. The left limit rotation detector 51, the origin point rotation detector 52, and the right limit rotation detector 53 are fixedly connected to the bracket. The left limit rotation detector 51 is used to detect the extreme leftward rotation position of the flipping mechanism, the origin point rotation detector 52 is used to detect the initial position where the flipping mechanism has not rotated, and the right limit rotation detector 53 is used to detect the extreme rightward rotation position of the flipping mechanism. By setting the left limit rotation detector 51, the origin point rotation detector 52, and the right limit rotation detector 53, the rotating mechanism 2 stops rotating when the flipping mechanism is at the extreme rightward rotation position, the initial position when it has not rotated, or the extreme leftward rotation position.

[0039] This embodiment also provides a full-bore commutation method, including:

[0040] Step 10) Use the first spool bracket 31 and the second spool bracket 39 to fill the spool;

[0041] Step 20) Use the rotating mechanism 2 to rotate the base 1 to the set position;

[0042] Step 30) Use the flipping mechanism 3 to roll the full yarn spool out from the first yarn spool bracket 31 and the second yarn spool bracket 39.

[0043] The method described in the above embodiment is simple and efficient. After the first spool support 31 and the second spool support 39 are filled with yarn, the base 1 is rotated to a set position using the rotating mechanism 2; finally, the full spool is rolled out from the first spool support 31 and the second spool support 39 using the flipping mechanism 3. During this reversal process, the first spool support 31 and the second spool support 39 are located on the flipping mechanism 3, which is located on the rotating mechanism 2. The reversal of the full spool is achieved through the rotating mechanism 2 and the flipping mechanism 3. The entire process is implemented on the rotating mechanism 2 and the flipping mechanism 3.

[0044] Preferably, the full-spool reversing method further includes: step 40) returning the flipping mechanism 3 to its initial position. Since there are many full-spools, after the previous full-spool is reversed and rolls out of the first spool bracket 31 and the second spool bracket 39, the flipping mechanism 3 returns to its initial position to prepare for receiving the next full-spool.

[0045] Preferably, step 40) further includes: returning the rotating mechanism 3 to its initial position. The direction in which the first yarn spool bracket 31 and the second yarn spool bracket 39 receive the full yarn spool is different from the direction in which the full yarn spool rolls out of the first yarn spool bracket 31 and the second yarn spool bracket 39. After the previous full yarn spool has changed direction and rolled out of the first yarn spool bracket 31 and the second yarn spool bracket 39, the rotating mechanism 3 returns to its initial position to prepare for receiving the next full yarn spool.

[0046] In step 20) of the above embodiment, the base 1 is rotated to a set position using the rotating mechanism 2. Due to different process requirements, such as... Figure 1 As shown, the full-bore spool may roll forward or backward. Forward rolling means rolling inwards towards the paper, while backward rolling means rolling outwards towards the paper. The next process device is located on both the front and rear sides of the reversing mechanism. Let the direction of the full-bore spool from the previous process be the left large end (end A) and the right small end (end B). Both the rotating mechanism and the flipping mechanism are in their initial positions (i.e., the origin).

[0047] As a work method, left-reversed palletizing (AB ends), such as Figure 1 As shown, preferably, in step 20), the base 1 is rotated to the left using the rotating mechanism 2. When the left limit rotation detector 51 detects the rotating table, the rotating mechanism 2 stops rotating; the information that the rotating mechanism 2 has stopped rotating is transmitted to the flipping mechanism 3. In step 30), the drive screw nut 37 moves forward, and the screw nut 37 drives the first wire drum bracket 31 and the second wire drum bracket 39 to flip backward; when the first wire drum bracket 31 and the second wire drum bracket 39 are below the horizontal plane, the full wire drum tumbles and falls; when the current limit flipping detector 41 detects the screw nut 37, the second power source stops working.

[0048] After the full spool is reversed and rolled out of the first spool bracket 31 and the second spool bracket 39, the first spool bracket 31 and the second spool bracket 39 need to return to their initial positions to receive the next full spool. Preferably, the full spool reversal method further includes: obtaining a stop signal from the second power source, moving the lead screw nut 37 backward, causing the spool bracket to flip forward; when the origin position flip detector 42 detects the lead screw nut 37, the second power source stops working and transmits a signal to the first power source; after receiving the signal, the first power source rotates the base 1 to the right; when the origin position rotation detector 52 detects the base 1, the first power source stops working. The spool bracket flips back to its initial position, and then the rotation mechanism 2 returns to its initial position. In this way, the first spool bracket 31 and the second spool bracket 39 can receive the next full spool.

[0049] As another operational method, right-hand reversing palletizing (BA end), such as... Figure 1As shown, preferably, in step 20), the base 1 is rotated to the right using the rotating mechanism 2. When the right limit rotation detector 53 detects the base 1, the rotating mechanism stops rotating; the information that the rotating mechanism has stopped rotating is transmitted to the flipping mechanism 3; in step 30), the lead screw nut 37 is driven to move backward, and the lead screw nut drives the first yarn drum bracket 31 and the second yarn drum bracket 39 to flip forward; when the first yarn drum bracket 31 and the second yarn drum bracket 39 are below the horizontal plane, the full yarn drum tumbles and falls; when the rear limit flipping detector 43 detects the lead screw nut 37, the second power source stops working.

[0050] After the full spool is reversed and rolled out of the first spool bracket 31 and the second spool bracket 39, the first spool bracket 31 and the second spool bracket 39 need to return to their initial positions to receive the next full spool. Preferably, the full spool reversal method further includes: obtaining a stop signal from the second power source, moving the lead screw nut 37 forward, causing the spool bracket to flip backward; when the origin position flip detector 42 detects the lead screw nut 37, the second power source stops working and transmits a signal to the first power source; after receiving the signal, the first power source rotates the base 1 to the left; when the origin position rotation detector 52 detects the base 1, the first power source stops working. The spool bracket flips back to its initial position, and then the rotation mechanism 2 returns to its initial position. In this way, the first spool bracket 31 and the second spool bracket 39 can receive the next full spool.

[0051] The embodiments of the present invention can automatically reverse the direction of full yarn bobbins taken from the false twisting machine to meet the requirements of left and right stacking for the direction of full yarn bobbins. This avoids the need for manual removal of yarn bobbins from high places and reversal of the yarn bobbins according to the direction of the hanging rod on the yarn cart, greatly reducing the intensity of manual labor and improving work efficiency.

[0052] In this embodiment of the invention, the rotating mechanism 2 can rotate left and right. The flipping mechanism 3 is powered by a motor-driven lead screw nut 37, which has high positioning accuracy, ensuring precise output positioning. The lead screw nut 37 is connected to the connecting rod 34, and the two yarn drum supports and the support frame are connected as a whole through the intermediate connecting shaft 38. This structure effectively realizes the driving of two symmetrical yarn drum supports by a single power output, and ensures that the movements of the two yarn drum supports are consistent, avoiding the offset caused by inconsistent movements of the yarn drum supports during the flow of the full yarn drum, which would affect the flow of the full yarn drum in the next process.
