Description

Technical Field

[0001] This application relates to the field of texturing machines, and in particular to a blanking buffer mechanism for automatic bobbin unloading of a texturing machine. Background Art

[0002] A texturing machine is a textile machine that can process raw filaments such as polyester and polypropylene into elastic filaments with medium and low elastic properties through false twist deformation. The raw filaments are heated, cooled, false twisted, shaped, and finally recovered through a winding frame.

[0003] The winding frame includes a mounting table, the mounting table has a rotating handle and a turntable, both ends of the bobbin are clamped by the turntable. After the bobbin on the mounting table is full, the full bobbin needs to be removed, and an empty bobbin also needs to be reinstalled on the winding frame so that the raw filaments can continue to be recovered.

[0004] When removing the full bobbin, it is necessary to lift the bobbin. During the lifting process, through the frictional resistance of the hand on the full bobbin, the bobbin can be quickly stopped from rotating, and then removed. During the process of the palm rubbing against the bobbin, the skin on the hand is prone to wear and the epidermis is polished after long-term work. If gloves are worn, the raw filaments on the bobbin will also be rubbed and prone to breakage. Existing automatic bobbin unloading equipment can only clamp both ends of the bobbin and let the bobbin stop rotating under natural clamping. If the clamping force is increased, it will damage the barrel body of the bobbin. If it is simply clamped, the speed at which the bobbin stops rotating is still not fast enough, resulting in low efficiency of automatic bobbin unloading. Summary of the Invention

[0005] The purpose of the present utility model is to overcome the above-mentioned deficiencies of the prior art and provide a blanking buffer mechanism for automatic bobbin unloading of a texturing machine, which can quickly slow down the rotation speed when unloading a full bobbin.

[0006] In order to achieve the above purpose, the present application adopts the following technical solutions:

[0007] A blanking buffer mechanism for automatic bobbin unloading of a texturing machine includes a blanking buffer component and a winding frame with multiple mounting tables. The mounting table has a rotating handle and a turntable, and the end of the bobbin is clamped by the turntable. The blanking buffer component includes a jaw table that moves back and forth towards the winding frame and a lifting and pressing mechanism. The jaw table is connected with a jaw arm, and the jaw arm is provided with a plurality of rotating wheels that abut against the bobbin; the lifting and pressing mechanism includes a lifting and pressing front and rear moving table that slides back and forth relative to the winding frame and a lifting and pressing left and right moving table that slides left and right relative to the winding frame. The lifting and pressing left and right moving table is rotatably provided with a buffer cylinder, and the buffer cylinder can abut against the bobbin.

[0008] Preferably, the jaw arm is provided with a clamping groove, and part of the position of the rotating wheel is located in the clamping groove.

[0009] Preferably, the clamping groove is arc-shaped, and the radian of the arc is the same as that of the reel.

[0010] Preferably, the buffer cylinder includes a fixed rod fixedly connected to the left-right lifting and moving table and a sleeve rotatably arranged on the fixed rod, and the sleeve is made of rubber.

[0011] Preferably, a bearing is arranged between the fixed rod and the sleeve, the inner ring of the bearing is connected to the fixed rod, and the outer ring of the bearing is connected to the sleeve.

[0012] Preferably, there are three rotating wheels, the three rotating wheels are distributed in a triangle, and the three rotating wheels are respectively located at the head, middle and tail ends of the clamping groove.

[0013] Preferably, the central axis of the buffer cylinder is parallel to the central axis of the rotating wheel.

[0014] Preferably, the rotating wheel is made of rubber.

[0015] In summary, the utility model includes the following beneficial technical effects:

[0016] After the reel is disassembled, the buffer cylinder abuts against the reel. Under the resistance of the rotation of the buffer cylinder, the rotating cylinder can stop rotating quickly, thereby reducing the frictional loss of the clamping arm on the reel and ultimately improving the service life of the reel.

They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components.

The axial direction of the two turntables 14 is the left - right direction of the winding frame 1. When it is necessary to unload the reel 11, first lift the mounting platform 12, and then move the turning handle 13 to one side, so that one of the turntables 14 that clamps the reel 11 leaves one end of the reel 11. Then the reel 11 is disassembled and taken from the end where the turntable 14 has left.

[0049] Reference Figure 1 , Figure 2 , Figure 8 and Figure 9 The clamping platform 3 includes a clamping base 31 and a plurality of clamping modules 32. The clamping modules 32 are stacked in sequence. The clamping base 31 is fixedly connected to the mobile platform 2. The clamping base 31 is connected to the clamping module 32 at the bottom through a screw drive. The remaining clamping modules 32 are stacked on the clamping module 32 at the bottom. When the clamping module 32 at the bottom moves back and forth toward the winding frame 1, the remaining clamping modules 32 move synchronously.

[0050] Reference Figures 8 - 11 The clamping module 32 includes a fixed seat 321 and a telescopic plate 322.

The moving direction of the upper arm 351 and the lower arm 352 is to move up and down relative to the winding frame 1.

[0054] Reference Figures 7 - 11 Under the action of the yielding driving member 33 , the yielding plate 34 can be driven to move, thereby causing the clamping arm 35 to move along the axial direction of the turntable 14 .

[0055] After the clamping arm 35 takes down the full reel 11 from the mounting platform 12 , the buffer cylinder 56 can abut against the reel 11 under the drive of the lifting and pressing mechanism 5 , so that the rotation speed of the reel 11 is quickly slowed down.

[0056] Reference Figures 1 - 4 The unloading buffer mechanism also includes a material changing mechanism 4 and a standby rack 7, and the standby rack 7 can hold an empty roll 11 or a full roll 11. The material changing mechanism 4 is used to transfer the empty roll 11 from the standby rack 7 to the clamp arm 35, or to transfer the full roll 11 on the clamp arm 35 to the standby rack 7.

The material changing platform 43 is provided with a chuck 44, and the chuck 44 can clamp an empty roll 11 or a full roll 11. The material changing platform 43 can rotate relative to the material changing rotating seat 42, thereby changing the direction of the chuck 44, so that the chuck 44 can be directed toward the clamping arm 35 or toward the standby rack 7.

[0059] Reference Figures 3 - 5 The refueling base 41 is provided with two refueling moving position sensors 411, and the refueling rotating base 42 is fixed with a refueling moving sensing sheet 412. The two refueling moving position sensors 411 are located in the moving path of the refueling moving sensing sheet 412. One of the two refueling moving position sensors 411 is close to the clamping platform 3, and the other is far away from the clamping platform 3.

[0060] Reference Figures 3 - 5, when the material change moving induction piece 412 moves to the material change moving position inductor 411 close to the jaw table 3, the chuck 44 is just placing the empty reel 11 on the clamping arm 35, or is just taking down the full reel 11 on the clamping arm 35; when the material change moving induction piece 412 moves away from the material change moving position inductor 411 of the jaw table 3, the orientation of the chuck 44 needs to be changed so that the chuck 44 faces the stock shelf 7 or the clamping arm 35 of the jaw table 3.

[0061] Refer to Figures 3 - 5 , the material change table 43 is provided with a toothed disk 431, the material change rotating seat 42 is provided with a material change rotation driving part 421, and the output shaft of the material change rotation driving part 421 is connected with the toothed disk 431 through gear transmission; the material change rotation driving part 421 is a motor, and the material change rotation driving part 421 can drive the toothed disk 431 to rotate the material change table 43. Thus, the orientation of the chuck 44 is changed.

[0062] Refer to Figure 5 , the material change rotating seat 42 is provided with a first material change rotation position inductor 422 and a second material change rotation position inductor 423, the material change table 43 is fixedly provided with a material change rotation induction piece 424, and the first material change rotation position inductor 422 and the second material change rotation position inductor 423 are located on the moving path of the material change rotation induction piece 424.

[0063] Refer to Figures 3 - 5 , after the material change moving induction piece 412 moves away from the material change moving position inductor 411 of the jaw table 3, the material change table 43 rotates under the drive of the material change rotation driving part 421. At this time, the material change rotation induction piece 424 can move between the first material change rotation position inductor 422 and the second material change rotation position inductor 423.

[0064] Refer to Figures 3 - 5 , when the material change rotation induction piece 424 moves to the first material change rotation position inductor 422, the chuck 44 just faces the clamping arm 35 on the jaw table 3, and when the material change rotation induction piece 424 moves to the second material change rotation position inductor 423, the chuck 44 just faces the stock shelf 7.

[0065] Refer to Figure 5 , the material change table 43 is fixedly provided with a limit projection 432, the toothed disk 431 is provided with a limit groove 433, and the limit projection 432 is located in the limit groove 433.

[0066] Refer to Figure 5 , the limit groove 433 has two working ends. As the material change table 43 rotates, the limit projection 432 can move to one of the working ends or the other working end of the limit groove 433. Thus, the rotation range of the material change table 43 is limited.

[0067] Refer to Figure 5 andFigure 6 Moreover, the material changing table 43 is further provided with a lateral rotation driving member 45, and the lateral rotation driving member 45 is in transmission connection with the chuck 44.

[0068] Specifically, the lateral rotation driving member 45 is a motor. The chuck 44 has a rotating shaft 441, and the lateral rotation driving member 45 is in transmission connection with the rotating shaft 441 in a belt drive form. The material changing table 43 is further provided with an arc-shaped anti-sway plate 442. An elastic member is built in the arc-shaped anti-sway plate 442, and the elastic member has a tendency to force the arc-shaped anti-sway plate 442 to move towards the rotating shaft 441. The arc surface of the arc-shaped anti-sway plate 442 abuts against the rotating shaft 441.

[0069] Refer to Figure 5 and Figure 6 , the chuck 44 has a first jaw 444 and a second jaw 445. The lateral rotation driving member 45 can drive the chuck 44 to rotate, so that the first jaw 444 and the second jaw 445 rotate around the rotating shaft 441. After the clamping arm 35 (such as Figure 3 ) takes the reel 11 from the winding rack 1, the central axes of the first jaw 444 and the second jaw 445 can be collinear with the central axis of the reel 11 between the upper arm 351 and the lower arm 352. After the central axis of the first jaw 444 or the second jaw 445 is collinear with the central axis of the reel 11, the material changing table 43 moves towards the clamping arm 35 direction, so that the first jaw 444 and the second jaw 445 take the reel 11 on the clamping arm 35.

[0070] Refer to Figure 6 and Figure 7 , preferably, the first jaw 444 and the second jaw 445 rotate under the action of the lateral rotation driving member 45, so that the first jaw 444 can be located directly above the second jaw 445 in the vertical direction, or the second jaw 445 can be located directly above the first jaw 444 in the vertical direction. The arc-shaped anti-sway plate 442 can improve the stability of the rotating shaft when the lateral rotation driving member 45 stops driving the chuck 44 to rotate, so that the first jaw 444 and the second jaw 445 will not relatively sway.

[0071] Refer to Figure 6 and Figure 7 , the lowest end of the empty cylinder groove 71 (such as Figure 1 ) is located on the moving path of the first jaw 444 or the second jaw 445, and the topmost end of the storage groove 72 is located on the moving path of the first jaw 444 or the second jaw 445.

[0072] Refer to Figure 6 and Figure 7, the first jaw 444 and the second jaw 445 have the same structure and function, and can be switched with each other. By rotating the chuck 44, after the chuck 44 unloads the full reel 11 on the clamping arm 35, it can also load the empty reel 11 onto the clamping arm 35, shortening the interval between loading and unloading on the clamping arm 35, thereby improving the overall working efficiency.

[0073] Refer to Figures 1 - 3 , the spare shelf 7 is provided with a plurality of empty cylinder slots 71 and storage slots 72. The empty cylinder slots 71 are used to place the empty reels 11, and the storage slots 72 are used to place the full reels 11. Both the empty cylinder slots 71 and the storage slots 72 are inclined. The material changing mechanism 4 can pick up the empty reel 11 at the bottom end of the empty cylinder slot 71. The staff can replenish the empty cylinder slots 71 with empty cylinders at any time, so that there is always an empty reel 11 at the bottom end of the empty cylinder slot 71. The material changing slot can put the full reel 11 into the highest end of the storage slot 72, and the full reel 11 in the storage slot 72 rolls into the lowest end of the storage slot 72 by itself. Keep the highest end of the storage slot 72 empty. It is convenient for the material changing mechanism 4 to put a new full reel 11 into the storage slot 72 each time.

[0074] Refer to Figures 1 - 7 , specifically: at the beginning, the first jaw 444 is directly above the second jaw 445, the chuck 44 faces the spare shelf 7, the material changing table 43 moves towards the spare shelf 7, and the first jaw 444 can pick up the empty reel 11 on the spare shelf 7. At this time, the second jaw 445 is in an empty state; after the clamping arm 35 picks up the full reel 11 of the winding rack 1, the chuck 44 will face the clamping arm 35, and the material changing table 43 moves towards the clamping arm 35, and the second jaw 445 picks up the full reel 11 on the clamping arm 35. Then the material changing table 43 temporarily moves away from the clamping arm 35, and the chuck 44 rotates to exchange the positions of the first jaw 444 and the second jaw 445. At this time, the full reel 11 is above and the empty reel 11 is below. Then the material changing table 43 moves towards the clamping arm 35 again, so that the empty reel 11 enters the clamping arm 35. Then the material changing table 43 moves towards the spare shelf 7 and loads the full reel 11 onto the storage slot 72 of the spare shelf 7; at the same time, the clamping arm 35 feeds the empty reel 11 into the installation table 12.

[0075] Refer to Figure 1 , Figure 8 , Figure 9 , Figures 12 - 15, specifically, first control the clamping arm 35 to make the distance between the upper arm 351 and the lower arm 352 greater than the diameter of the drum 11. First, drive the clamping module 32 to move towards the winding frame 1 through the screw drive of the jaw base 31, and then drive the clamping arm 35 so that the upper arm 351 and the lower arm 352 can clamp the drum 11. After clamping, drive the displacement plate 34 to move through the displacement driving member 33, so that the other end of the drum 11 also leaves the other turntable 14. Then move the clamping arm 35 backward. Thus, the drum 11 is removed from the mounting table 12. On the clamping arm 35 of the removed drum 11, the drum 11 on the clamping arm 35 is transported to the spare shelf 7 through the material changing mechanism 4.

[0076] Similarly, when an empty drum 11 needs to be installed on the mounting table 12, the material changing mechanism 4 and the jaw table 3 can also install the empty drum originally on the spare shelf 7 onto the mounting table 12. So that the empty drum 11 continues to collect the silk thread.

[0077] After the lifting and pressing mechanism 5 lifts the mounting table 12, the drum 11 will continue to rotate under the action of inertia. At this time, when the clamping arm 35 clamps the drum 11, the drum 11 will rotate relative to the clamping arm 35, and the contact position between the drum 11 and the clamping arm 35 will rub. Although the drum 11 can be stopped, the clamped position of the drum 11 will be worn due to friction.

[0078] Refer to Figure 11 and Figure 12 , therefore, rotating wheels are provided on both the upper arm 351 and the lower arm 352. Clamping grooves 353 are formed on the upper arm 351 and the lower arm 352. The clamping grooves 353 are arc-shaped, and the arc degree of the arc is the same as that of the drum 11. Part of the rotating wheel is located in the clamping groove 353. When the upper arm 351 and the lower arm 352 clamp the drum 11, the rotating wheel will abut against the drum 11, so that multiple rotating wheels clamp both ends of the drum 11. The rotating wheel is made of rubber material.

[0079] Refer to Figure 11 and Figure 12 , there are three rotating wheels, and the three rotating wheels are distributed in a triangle. The three rotating wheels are respectively located at the front end 354, the middle end 355 and the tail end 356 of the clamping groove 353.

[0080] Since there are multiple clamping modules 32, the lifting and pressing mechanism 5, the displacement plate 34 and the displacement driving member 33 are all provided with multiple; moreover, the numbers of the lifting and pressing mechanism 5, the displacement plate 34 and the displacement driving member 33 correspond to the number of the clamping modules 32 one by one.

[0081] A synchronous belt 57 is connected between the output ends of adjacent lifting and pressing front and rear moving driving members 523. When the lifting and pressing front and rear moving driving member 523 works, the adjacent lifting and pressing front and rear moving driving members 523 can achieve the effect of synchronous operation through the synchronous belt 57.

[0082] Reference Figure 1 , Figure 2 , Figure 12 , Figure 13 , Figure 16 and Figure 17 The clamping claw platform 3 is provided with a breaking slide rail 81, and the breaking slide rail 81 is located between the two clamping arms 35. The breaking slide rail 81 is slidably provided with a breaking wire platform 8.

[0083] Reference Figure 12 , Figure 13 , Figure 16 and Figure 17 The clamping platform 3 is also provided with a wire-breaking driving member 82, a driving wheel 83, a driven wheel 84 and a transmission belt 85. The wire-breaking driving member 82 is fixedly arranged on the clamping platform 3, and the driving wheel 83 is rotatably arranged on the clamping platform 3. The wire-breaking driving member 82 is a motor, and the driving end of the wire-breaking driving member 82 is connected to the driving wheel 83. The transmission belt 85 is sleeved on the driving wheel 83 and the driven wheel 84, and the wire-breaking platform 8 is also fixedly connected to the transmission belt 85. The wire-breaking slide rail 81 is parallel to the length direction of the winding frame 1. When the wire-breaking driving member 82 drives the driving wheel 83 to rotate, the wire-breaking platform 8 can move along the length direction of the wire-breaking slide rail 81, that is, move left and right relative to the winding frame 1.

[0084] Reference Figure 16 and Figure 17 , breaking position sensors 86 are respectively installed at both ends of the breaking slide rail 81. When the breaking wire platform 8 moves to one of the positions and is sensed by the breaking position sensor 86, the breaking wire driving member 82 will reverse, so that the breaking wire platform 8 moves toward the other breaking position sensor 86. Thus, the breaking wire platform 8 can reciprocate on the breaking slide rail 81.

[0085] Reference Figure 16 and Figure 17 The wire-breaking platform 8 has a toggling end 87 and a wire-breaking end 88 , wherein the toggling end 87 faces one of the clamping arms 35 , and the wire-breaking end 88 faces the other clamping arm 35 .

[0086] Reference Figure 16 and Figure 17 The toggling end 87 is mainly used to guide the silk thread. When the empty reel 11 is installed on the mounting platform 12, the end of the silk thread needs to be wound around the empty reel 11, and then the toggling end 87 of the wire breaking platform 8 is moved from the direction of the clamping arm 35 it is facing, so that the toggling end 87 can push the silk thread to be accommodated in a groove of the winding frame 1. The groove is used to reduce the problem of violent shaking of the silk thread when the reel 11 is wound around the silk thread. The groove is a prior art and is not shown in the figure.

[0087] Reference Figure 16 andFigure 17 , a blade is provided at the wire breaking end 88, which is not shown in the figure. The blade is mainly used for cutting the silk thread. When the full-winding reel 11 needs to be removed from the mounting table 12, the silk thread is first cut by the movement of the wire breaking end 88. After the silk thread is cut off, the reel 11 will no longer collect and wind the silk thread. Then, the reel 11 is removed from the winding rack 1 through the lifting and pressing mechanism 5 and the jaw table 3.

[0088] Refer to Figure 16 and Figure 17 , when the empty reel 11 is installed on the winding rack 1, the broken silk thread needs to be reconnected to the reel 11 first. By setting a suction and feeding mechanism 6 on the jaw table 3 (such as Figure 10 ), the silk thread can be reconnected to the reel 11.

[0089] Refer to Figure 1 , Figure 2 , Figures 8 - 13 , specifically, the suction and feeding mechanism 6 includes a suction and feeding lifting and moving table 61, a suction and feeding lifting driving part 611, a suction and feeding front and rear moving table 62, a suction and feeding front and rear driving part 621, a suction and feeding left and right moving table 63, a first suction and feeding left and right driving part 64, a second suction and feeding left and right driving part 631, a push plate 65 and a suction and feeding silk thread gun 66; the suction and feeding lifting and moving table 61 is slidably connected along the vertical direction of the jaw table 3, the suction and feeding lifting driving part 611 is fixedly arranged on the jaw table 3, and the driving end of the suction and feeding lifting driving part 611 is in transmission connection with the suction and feeding lifting and moving table 61, which can suck and drive the lifting and moving table 61 to move up and down.

[0090] Refer to Figure 9 and Figure 13 , the suction and feeding front and rear moving table 62 is slidably arranged on the suction and feeding lifting and moving table 61, the suction and feeding front and rear driving part 621 is fixedly arranged on the suction and feeding lifting and moving table 61, the suction and feeding front and rear driving part 621 is a motor, the output shaft of the suction and feeding front and rear driving part 621 is in transmission connection with the suction and feeding front and rear moving table 62, and the suction and feeding front and rear driving part 621 can make the suction and feeding front and rear moving table 62 move relative to the winding rack 1 back and forth.

[0091] Refer to Figure 9 and Figure 13 , the suction and feeding left and right moving table 63 is slidably connected to the suction and feeding front and rear moving table 62, the second suction and feeding left and right driving part 631 is fixedly arranged on the suction and feeding front and rear moving table 62, and the output end of the second suction and feeding left and right driving part 631 is in transmission connection with the suction and feeding left and right moving table 63, which can drive the suction and feeding left and right moving table 63 to move relative to the winding rack 1 left and right.

[0092] Refer to Figure 9 and Figure 13The first suction and delivery left and right driving member 64 is fixedly arranged on the suction and delivery left and right movable platform 63, and the push plate 65 is movably arranged on the suction and delivery left and right movable platform 63. The first suction and delivery left and right driving member 64 is a motor. The first suction and delivery left and right driving member 64 is transmission-connected with the push plate 65. The first suction and delivery left and right driving member 64 can drive the push plate 65 to move left and right relative to the winding frame 1. The transmission mode of the first suction and delivery left and right driving member 64 is screw rotation.

[0093] Reference Figure 9 and Figure 13 The suction wire gun 66 is arranged on the push plate 65, and the muzzle of the suction wire gun 66 faces the mounting platform 12 of the reel 11. As the push plate 65 moves left and right relative to the winding frame 1, the suction wire gun 66 can suck the wire, and when the wire needs to be wound onto the reel 11, the suction wire gun 66 can feed the wire, so that the wire contacts the reel 11, and the reel 11 keeps rotating under the action of the winding frame 1, so that the reel 11 can wind the wire.

[0094] Reference Figure 9 and Figure 13 Two suction position sensors 632 are arranged on the suction and delivery left and right movable platform 63, and the two suction and delivery position sensors 632 are located in the moving path of the push plate 65. When the second suction and delivery left and right driving member 631 drives the push plate 65 to move to one of the suction and delivery position sensors 632, the second suction and delivery left and right driving member 631 works in the reverse direction, allowing the push plate 65 to move toward the other suction and delivery position sensor 632. Through the reciprocating movement of the push plate 65, the suction and delivery silk thread gun 66 moves left and right relative to the winding frame 1, thereby facilitating the absorption of the broken silk thread onto the suction and delivery silk thread gun 66.

[0095] Specifically, after the empty reel 11 is placed in the winding frame 1, the broken wire is wound onto the reel 11 through the suction wire gun 66, and then the wire is moved by the moving end 87 of the wire-breaking table 8 so that the wire can be guided by the groove on the winding frame 1. When the reel 11 is full and needs to be removed, the wire is first cut by the wire-breaking end 88 of the wire-breaking table 8, and then the suction wire gun 66 sucks the broken wire. After the full reel 11 is unloaded by the clamping claw table 3 and the material changing mechanism 4, the new empty reel 11 will be installed on the winding frame 1, and the suction wire gun 66 will wind the sucked wire onto the reel 11, and this reciprocating cycle will be repeated.

[0096] Specific implementation method:

[0097] Reference Figures 1 - 17, the lifting and pressing assembly lifts the mounting platform 12, the wire breaking platform 8 cuts the wire, the wire suction gun 66 sucks the broken wire, the clamping claw platform 3 unloads the full reel 11 from the winding rack 1, and then the material changing mechanism 4 transfers the full reel 11 on the clamping claw platform 3 to the standby shelf 7, and then the material changing mechanism 4 transfers the empty reel 11 from the standby shelf 7 to the clamping claw platform 3, and the clamping claw platform 3 installs the empty reel 11 on the mounting platform 12, and the lifting and pressing assembly presses down the mounting platform 12 to keep the reel 11 rotating, and the wire suction gun 66 winds the wire around the empty reel 11, so that the reel 11 is in a state of winding and collecting the wire, and then the wire breaking platform 8 moves the wire, and the wire enters the groove of the winding rack 1, so that the wire is in a stable conveying state.
