Description

Technical Field

[0001] The present invention relates to the technical field of automatic yarn withdrawal, and more specifically, to an automatic yarn withdrawal conveying and separation and collection device. Background Art

[0002] Cone dyeing is a major trend in the development of yarn dyeing in yarn-dyed weaving, knitting, thread making and other enterprises. Cone dyeing is a yarn dyeing process that integrates scouring, bleaching, dyeing, soap boiling and other dyeing processes after the raw yarn is put into the cylinder. It has the characteristics of high labor productivity and high degree of automation.

[0003] The basic process of bobbin yarn dyeing is: loose yarn - cage - dyeing - drying - rewinding. Bobbin yarn needs to be caged before dyeing. One of the commonly used caged methods is to put multiple single bobbin yarns on an empty rod to form a rod yarn, and then put multiple rod yarns into a cage and put them into the dyeing tank for dyeing.

[0004] The dyed rod yarn needs to be dried, and the rod yarn needs to be untied after drying, that is, the bobbin yarn is separated from the empty rod, collected and transferred to the next process, and the separated empty rods also need to be collected and reused. At present, most factories use manual untiing, which is not only time-consuming and labor-intensive, but also has low production efficiency. In addition, workers are very likely to hit and damage the empty rods when untiing and collecting bobbin yarn and empty rods, resulting in loss and scrapping of the empty rods. To this end, we propose an automatic conveying, untiing and separation collection device to solve the above problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide an automatic yarn conveying, unwinding and separating and collecting device with high production efficiency.

[0006] To achieve the above technical objectives, the present invention provides the following technical solutions: an automatic conveying, yarn withdrawal and separation and collection device, comprising a conveying mechanism, a yarn withdrawal mechanism and a yarn outlet mechanism, the conveying mechanism is used to transfer the rod yarn to the yarn withdrawal mechanism, the yarn withdrawal mechanism comprises a vertical fixed seat, the fixed seat is provided with two rows of parallel slide rails one along its own length direction, a sliding plate is slidably arranged on the slide rail one, a clamping piece for clamping the rod yarn is arranged on the sliding plate, and a lifting cylinder for driving the sliding plate to slide along the slide rail one is arranged on the back side of the fixed seat; a mounting seat located above the clamping piece is fixedly arranged on the fixed seat, a vertical push rod is fixedly arranged on the mounting seat, and the diameter of the push rod is smaller than the empty rod of the rod yarn;

[0007] The yarn discharging mechanism includes two slide rails 2 horizontally placed outside the lower part of the push rod and pointing to the axis of the push rod, and a yarn receiving frame is slidably arranged on the two slide rails 2. The yarn discharging mechanism is provided with a rodless cylinder driving the yarn receiving frame to slide along the length direction of the slide rails 2, and a carton for storing bobbin yarn is arranged below the yarn receiving frame.

[0008] By adopting the above technical solution, the staff puts the rod yarn into the conveying mechanism in turn, and the rod yarn is sent to the yarn withdrawal mechanism. The clamping part clamps the rod yarn, and at the same time, the empty rod of the rod yarn is in the same straight line with the top rod. The lifting cylinder lifts the clamping part, and the empty rod of the rod yarn abuts the top rod. The empty rod is stationary relative to the top rod. The bobbin yarn on the empty rod will be pulled out by the clamping part and sleeved on the top rod. The gripper takes away the empty rod. The rodless cylinder moves the yarn receiving frame to the bottom of the top rod, and the clamping part is released. The bobbin yarn on the top rod falls on the yarn receiving frame in turn due to its own weight. The bobbin yarn rolls down the yarn receiving frame into the carton, completing the mechanized yarn withdrawal of the bobbin yarn, without manual yarn withdrawal, and improving work efficiency. At the same time, the top rod holds the empty rod vertically, and when withdrawing the yarn, the empty rod will not be damaged, avoiding the loss and scrapping of the empty rod.

[0009] Preferably, the clamping member comprises a double-headed cylinder fixed on a sliding plate, both ends of the double-headed cylinder are respectively provided with output rods that slide in a vertical direction along the slide rail, an extension plate is fixedly provided at the end of each output rod, and a clamping claw is provided at one end of the extension plate away from the output rod.

[0010] By adopting the above technical solution, after the two output rods of the double-headed cylinder are retracted, the two clamping claws will close to clamp the rod yarn; after the two output rods are extended, the two clamping claws will separate, and manual assembly of the rod yarn is unnecessary, thereby improving processing efficiency.

[0011] Preferably, the conveying mechanism includes a conveyor belt pointing to directly below the top rod, and two parallel guide rods are arranged above the conveyor belt. The two guide rods are parallel to the length direction of the conveyor belt, and the gap between the two guide rods is the same as the diameter of the bobbin yarn. A material blocking cylinder is arranged at one end of the guide rod close to the yarn withdrawal mechanism.

[0012] By adopting the above technical solution, the two guide rods limit the moving direction of the rod yarn, and the rod yarn can only move with the conveyor belt, ensuring the accuracy of the rod yarn delivery. The material blocking cylinder is controlled by the controller. When one rod yarn is located in the clamping part, the controller controls the clamping part and starts the material blocking cylinder to block the other rod yarns on the conveyor belt to prevent two rod yarns from being continuously sent to the clamping part and affecting the normal operation of the clamping part.

[0013] Preferably, a lifting mechanism is provided directly below the yarn withdrawal mechanism, the lifting mechanism comprises a limit support rod for supporting the chassis of the empty rod, and the lifting mechanism is provided with a cylinder for driving the limit support rod to vertically lift;

[0014] A manipulator capable of clamping the top end of the rod yarn is arranged above the conveyor belt, and a conveyor chain for driving the manipulator to slide along the length direction of the conveyor belt is arranged above the conveyor belt.

[0015] By adopting the above technical solution, after the rod yarn moves to the end of the conveyor belt, the manipulator clamps the top of the rod yarn, and at the same time the conveyor chain sends the manipulator and the rod yarn to the limiting support rod, the cylinder of the lifting mechanism lifts the limiting support rod, and the top of the empty rod of the rod yarn tightly abuts against the bottom end of the top rod, the manipulator releases and resets, realizing the transfer of the rod yarn and the fixation of the empty rod, so as to prevent the empty rod from moving with the bobbin yarn when the clamp pulls off the bobbin yarn.

[0016] Preferably, an empty rod transfer mechanism is provided outside the yarn retracting mechanism, and the empty rod transfer mechanism includes a support rod outside the fixed seat, and two gripping claws are hinged on the support rod and opened and closed by a cylinder. The empty rod transfer mechanism is provided with a cylinder for driving the support rod to slide in the horizontal and vertical directions along the fixed seat, and the two gripping claws are used to clamp the empty rod.

[0017] By adopting the above technical scheme, after all the bobbins on the rod yarn are taken away, the cylinder is started to open the gripping claws, and then the support rod is moved to the front of the fixed seat so that the empty rod is located between the two gripping claws. The empty rod can be grasped by closing the gripping claws, and the support rod is reset to remove the empty rod without affecting the subsequent rod yarn processing. The empty rods between the gripping claws are taken away by the rod retracting claws, and the gripping claws can grab the next batch of empty rods, thereby improving work efficiency.

[0018] Preferably, a group of rod collecting claws for taking away empty rods are arranged on the back of the fixed seat, and a rod collecting box for storing empty rods is arranged on the back of the fixed seat. A rodless cylinder for driving the rod collecting claws to slide along the horizontal and vertical directions of the fixed seat is arranged above the rod collecting box. A group of rod collecting claws has two rod collecting claws, and the opening and closing of the two rod collecting claws are controlled by the cylinder.

[0019] By adopting the above technical scheme, after the gripping claw clamps the empty rod out of the gripping claw, the rodless cylinder moves the rod collecting claw to the front of the fixed seat and grabs the empty rod grasped by the gripping claw. When the gripping claw is released, the rodless cylinder resets and moves the empty rod to just above the rod collecting box. After the rod collecting claw is released, the empty rod falls into the rod collecting box due to its own weight. There is no need to manually collect the empty rods, thereby improving work efficiency.

[0020] Preferably, the rodless cylinder is provided with a rotary motor for controlling the rotation of the two rod-collecting claws.

[0021] By adopting the above technical scheme, the rod collecting claw and the rodless cylinder transport the empty rods to the top of the rod collecting box, and the rotating motor controls the rotation of the rod collecting claw to turn the vertical empty rod into a horizontal one. At the same time, the rod collecting claw is released, and the empty rod falls horizontally into the rod collecting box. The empty rods can be stacked in the rod collecting box in sequence, reducing the gap between adjacent empty rods, ensuring that as many empty rods as possible can be placed in the rod collecting box, reducing the frequency of cleaning the rod collecting box, and reducing the labor burden of workers.

[0022] In summary, the present invention has achieved the following effects:

[0023] 1. With the cooperation of the conveying mechanism, the yarn withdrawing mechanism and the yarn discharging mechanism, the automatic collection of the yarn on the empty rod is realized.

[0024] 2. With the help of the cooperation of the lifting mechanism and the yarn withdrawal mechanism, it is ensured that the top rod presses the empty rod tightly to prevent the bobbin yarn on the empty rod from being unable to be removed;

[0025] 3. With the cooperation of the empty rod transfer mechanism and the yarn discharging mechanism, the package yarn and the empty rod can be automatically collected separately without manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0035] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0036] Embodiment: An automatic conveying, unwinding and separating and collecting device, such as Figure 1 As shown, it comprises a conveying mechanism 1 , a yarn withdrawing mechanism 2 and a yarn discharging mechanism 3 , and the conveying mechanism 1 is used to transfer the rod yarn to the yarn withdrawing mechanism 2 .

[0037] like Figure 2 As shown, the yarn retracting mechanism 2 includes a vertical fixed seat 21, and the fixed seat 21 is provided with two rows of parallel slide rails 22 along its own length direction, a sliding plate 23 is slid on the slide rail 22, and a clamping piece 24 for clamping the rod yarn is provided on the sliding plate 23, and a lifting cylinder for driving the sliding plate 23 to slide along the slide rail 22 is provided on the back of the fixed seat 21; a mounting seat 25 located above the clamping piece 24 is fixedly provided on the fixed seat 21, and a vertical push rod 26 is fixedly provided on the mounting seat 25, and the diameter of the push rod 26 is smaller than the empty rod 11 of the rod yarn.

[0038] like Figure 2 As shown, the clamping member 24 includes a double-headed cylinder 241 fixed on the sliding plate 23, and output rods sliding along the vertical direction of the slide rail are respectively arranged at both ends of the double-headed cylinder 241, and an extension plate 242 is fixedly arranged at the end of each output rod, and a clamping claw 243 is arranged at one end of the extension plate 242 away from the output rod. After the two output rods of the double-headed cylinder 241 are retracted, the two clamping claws 243 will close to clamp the rod yarn, and after the two output rods are extended, the two clamping claws 243 will separate, and there is no need to manually assemble the rod yarn, thereby improving the processing efficiency.

[0039] like Figure 3 As shown, the yarn discharging mechanism 3 includes two slide rails 31 horizontally placed outside the lower part of the top rod 26 and pointing to the axis of the top rod 26, and a yarn receiving frame 32 is slidably arranged on the two slide rails 31. The yarn discharging mechanism 3 is provided with a rodless cylinder driving the yarn receiving frame 32 to slide along the length direction of the slide rails 31, and a carton 33 for storing bobbin yarn is arranged below the yarn receiving frame 32.

[0040] The staff puts the rod yarn into the conveying mechanism 1 in turn, and the rod yarn is sent to the yarn withdrawal mechanism 2. The clamping piece 24 clamps the rod yarn. At the same time, the empty rod 11 of the rod yarn is in the same straight line with the top rod 26, and the lifting cylinder lifts the clamping piece 24. The empty rod 11 of the rod yarn abuts against the top rod 26. The empty rod 11 is stationary relative to the top rod 26, and the tube yarn on the empty rod 11 will be pulled out by the clamping piece 24 and sleeved on the top rod 26. The gripper 52 takes away the empty rod 11, and the rodless cylinder moves the yarn receiving frame 32 to the bottom of the top rod 26. The clamping piece 24 is released, and the tube yarn on the top rod 26 falls on the yarn receiving frame 32 in turn due to its own weight, and the tube yarn rolls along the yarn receiving frame 32 into the carton 33, completing the mechanized yarn withdrawal of the tube yarn. There is no need for manual yarn withdrawal, which improves work efficiency. At the same time, the push rod 26 holds the empty rod 11 vertically, so that the empty rod 11 will not be damaged when the yarn is withdrawn, thereby avoiding the loss and scrapping of the empty rod 11.

[0041] like Figure 4 As shown, the conveying mechanism 1 includes a conveyor belt 12 pointing to the bottom of the top rod 26, and two parallel guide rods 13 are arranged above the conveyor belt 12. The two guide rods 13 are parallel to the length direction of the conveyor belt 12, and the gap between the two guide rods 13 is the same as the diameter of the tube yarn. A material blocking cylinder 14 is arranged at one end of the guide rod 13 close to the yarn withdrawal mechanism 2. The two guide rods 13 limit the moving direction of the rod yarn, and the rod yarn can only move with the conveyor belt 12, thereby ensuring the accuracy of the rod yarn transportation. The material blocking cylinder 14 is controlled by a controller. When a rod yarn is located in the clamping member 24, the controller controls the clamping member 24 and starts the material blocking cylinder 14 at the same time, blocking the other rod yarns on the conveyor belt 12, preventing two rod yarns from being continuously sent to the clamping member 24, which affects the normal operation of the clamping member 24.

[0042] like Figure 4 and Figure 5 As shown, a lifting mechanism 4 is arranged directly below the yarn withdrawal mechanism 2, and the lifting mechanism 4 includes a limit support rod 41 for supporting the chassis of the empty rod 11, and the lifting mechanism 4 is provided with a cylinder for driving the limit support rod 41 to vertically lift and lower, and a manipulator 42 that can clamp the top of the rod yarn is arranged above the conveyor belt 12, and a conveyor chain 43 that drives the manipulator 42 to slide along the length direction of the conveyor belt 12 is arranged above the conveyor belt 12, and a cylinder for lifting the manipulator 42 is arranged on the conveyor chain 43. After the rod yarn moves to the end of the conveyor belt 12, the manipulator 42 clamps the top of the rod yarn, and at the same time, the conveyor chain 43 sends the manipulator 42 and the rod yarn to the limit support rod 41 to realize the transfer of the rod yarn. The cylinder of the lifting mechanism 4 lifts the limit support rod 41, and the top of the empty rod 11 of the rod yarn tightly abuts the bottom end of the push rod 26. The manipulator 42 is released and reset, thereby fixing the empty rod 11 to prevent the empty rod 11 from moving with the bobbin yarn when the clamp 243 pulls off the bobbin yarn.

[0043] like Figure 6As shown, an empty rod transfer mechanism 5 is provided outside the yarn withdrawal mechanism 2, and the empty rod transfer mechanism 5 includes a support rod 51 outside the fixed seat 21, and two gripping claws 52 are hinged on the support rod 51 and opened and closed by a cylinder drive, and the empty rod transfer mechanism 5 is provided with a cylinder that drives the support rod 51 to slide along the horizontal and vertical directions of the fixed seat 21, and the two gripping claws 52 are used to clamp the empty rod 11. After all the bobbins on the rod yarn are taken away, the cylinder is started to open the gripping claws 52, and then the support rod 51 is moved to the front of the fixed seat 21, so that the empty rod 11 is located between the two gripping claws 52, and the empty rod 11 can be grasped by closing the gripping claws 52, and the support rod 51 is reset to remove the empty rod 11, which does not affect the subsequent rod yarn processing, and the empty rods 11 between the gripping claws 52 are taken away, and the gripping claws 52 can grab the next batch of empty rods 11.

[0044] like Figure 7 As shown, a group of rod collecting claws 53 for taking away the empty rod 11 are arranged on the back of the fixed seat 21, and a rod collecting box 54 for storing the empty rods 11 is arranged on the back of the fixed seat 21. A rod collecting box 54 for storing the empty rods 11 is arranged above the rod collecting box 54. A rodless cylinder for driving the rod collecting claws 53 to slide in the horizontal and vertical directions along the fixed seat 21 is arranged. A group of rod collecting claws 53 has two, and the two rod collecting claws 53 are controlled to open and close by the cylinder. After the gripping claws 52 clamp the empty rod 11 out of the clamping claws 243, the rodless cylinder moves the rod collecting claws 53 to the front of the fixed seat 21 and grabs the empty rod 11 gripped by the gripping claws 52. After the gripping claws 52 are released, the rodless cylinder resets and moves the empty rod 11 to the top of the rod collecting box 54. After the rod collecting claws 53 are released, the empty rod 11 falls into the rod collecting box 54 due to its own weight. There is no need to manually collect the empty rods 11, thereby improving work efficiency.

[0045] like Figure 7 As shown, a rotating motor 55 is provided on the rodless cylinder to control the rotation of two rod collecting claws 53. The rod collecting claws 53 and the rodless cylinder transport the empty rods 11 to the top of the rod collecting box 54, and the rotating motor 55 controls the self-rotation of the rod collecting claws 53 to turn the vertical empty rods 11 into horizontal ones. At the same time, the rod collecting claws 53 are released, and the empty rods 11 fall horizontally into the rod collecting box 54. The empty rods 11 can be stacked in the rod collecting box 54 in sequence, reducing the gap between adjacent empty rods 11, ensuring that as many empty rods 11 as possible can be placed in the rod collecting box 54, reducing the cleaning frequency of the rod collecting box 54, and reducing the labor burden of workers.

[0046] Working process: The staff sequentially places the rod yarn on the conveyor belt 12 of the conveying mechanism 1. After the rod yarn moves to the end of the conveyor belt 12, the stopper cylinder 14 stops the rod yarn from moving further. After starting the device, the manipulator 42 on the conveyor belt 12 clamps the top of the empty rod 11 of the frontmost rod yarn, the stopper cylinder 14 contracts, the conveyor chain 43 drives the manipulator 42 to move forward, and the stopper cylinder 14 extends again.

[0047] The front end of the rod yarn moves to the limit support rod 41 of the lifting mechanism 4, and the cylinder of the lifting mechanism 4 lifts the limit support rod 41, and the empty rod 11 of the rod yarn presses tightly against the top rod 26, and the manipulator 42 releases the rod yarn and resets it. At the same time, the double-headed cylinder 241 of the clamping part 24 drives the output rod to contract, and the clamping claw 243 clamps the bobbin yarn on the rod yarn, and the lifting cylinder drives the sliding plate 23 to rise, thereby driving the bobbin yarn on the rod yarn to rise relative to the empty rod 11, and the bobbin yarn on the empty rod 11 is pulled out and sleeved on the top rod 26.

[0048] The lifting mechanism 4 is lowered, and the empty rod 11 is separated from the top rod 26. At the same time, the two claws 52 of the empty rod transfer mechanism 5 are opened, and the cylinder pushes the two claws 52 to the empty rod 11. The two claws 52 clamp the empty rod 11, and the cylinder drives the claws 52 to leave the fixed seat 21. At the same time, the rodless cylinder moves the rod collecting claw 53 to the empty rod 11 and grasps it. The rod collecting claw 53 is reset to move the empty rod 11 to the carton 33. The rotating motor 55 drives the rod collecting claw 53 to rotate, and the rod collecting claw 53 is released, and the empty rod 11 falls into the carton 33.

[0049] The yarn receiving frame 32 of the yarn discharging mechanism 3 is pushed to the bottom of the clamping member 24 by the rodless cylinder, the clamping member 24 is loosened, and the bobbins fall into the yarn withdrawing frame in sequence, and the bobbins fall into the carton 33 due to their own weight, thereby realizing the collection of the bobbins.
