Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, and in particular to a yarn-laying drum mechanism with sorting function. Background Technology
[0002] In the operation of an automatic winding machine, when the yarn on the bobbin is exhausted, the empty bobbin needs to be discharged and transported to an empty bobbin collection container. This process typically includes:
[0003] Yarn depletion detection: The winding machine detects that the yarn on the bobbin has been depleted through a yarn detection device. Once yarn depletion is detected, the yarn detection device will send a signal.
[0004] Yarn tube transfer mechanism: The drive transmission mechanism moves the yarn inserter towards the empty yarn tube conveyor belt. The empty yarn tube is kicked into the conveyor belt, ready for replacement with a new yarn tube.
[0005] Replenishing full yarn: The stepper motor rotates the ratchet by one tooth via the transmission rod, causing the yarn feeder to rotate at a certain angle. The full yarn is then replenished into the yarn inserter, and the yarn inserter is then moved back to the working position.
[0006] However, in actual production, unwound yarn tubes are often discharged and conveyed. During this process, the unwound yarn ends easily adhere to the empty tube conveyor belt. When passing the machine head, a large amount of spun yarn is easily generated at the machine head. In severe cases, when these spun yarns accumulate to a certain thickness, they will affect the normal operation of the empty tube conveying device. Some existing empty tube sorting devices only distinguish whether the empty tube has been unwound by using a fixed blocking limit on the diameter of the empty tube. However, when there are few unwound yarns wrapped on the empty tube, the thickness of the yarn winding may be very thin and not enough to form an effective blocking thickness. The empty tube may still break through the blocking under the drive of the conveying device, causing sorting failure and affecting the normal operation of the device. Utility Model Content
[0007] To address the problem in existing automatic winding machines that do not thoroughly sort empty yarn tubes and easily miss empty tubes with a small amount of unwound yarn, this utility model provides a yarn tray mechanism with sorting function.
[0008] The technical solution adopted in this utility model is:
[0009] A yarn-laying drum mechanism with sorting function includes a conveying platform and a sorting mechanism, wherein the sorting mechanism is disposed on the conveying platform;
[0010] The sorting mechanism includes a sorting bracket and a sorting blocking component. The bottom of the sorting bracket is fixedly set on the conveying platform and is respectively set on both sides of the conveying platform. The sorting blocking component is vertically connected between the sorting brackets and the outer surface of the sorting blocking component is provided with a velvet friction layer.
[0011] The conveying platform is equipped with a conveyor belt, which is located between the sorting supports on both sides. The conveyor belt is used to transport empty yarn tubes from the yarn discharge cylinder to the sorting blocking component.
[0012] Furthermore, the sorting bracket is provided with a lifting guide groove, the sorting blocking member is slidably disposed in the lifting guide groove, and the two ends of the sorting blocking member are connected to a lifting drive mechanism.
[0013] Furthermore, the lifting drive mechanism includes a lifting drive cylinder, which is vertically disposed on the side of the sorting bracket away from the sorting obstruction. The lifting drive cylinder is connected to a cylinder piston rod, and the end of the cylinder piston rod is fixedly connected to the end of the sorting obstruction.
[0014] Furthermore, the conveyor belt surface is provided with multiple transport grooves evenly arranged;
[0015] The transport trough is a strip-shaped trough with an arc-shaped bottom surface. The width of the transport trough is set to be greater than or equal to the diameter of the empty yarn tube, and the length direction of the transport trough is parallel to the setting direction of the sorting blocking component.
[0016] Furthermore, the sorting blocking member is configured as a blocking side and a passing side on both sides of the conveyor belt in the conveying direction. The blocking side of the sorting blocking member on the conveying platform is provided with a sorting discharge mechanism, which is used to discharge the empty yarn tubes blocked by the sorting blocking member from the conveying platform.
[0017] Furthermore, the sorting and discharge mechanism includes a discharge drive base disposed on one side of the conveyor platform and a telescopic striking rod connected to the discharge drive base, wherein the telescopic striking rod is connected to the end of the discharge drive base facing the conveyor belt.
[0018] The drive base is equipped with a hydraulic drive mechanism or a pneumatic drive mechanism, both of which are used to provide power for the telescopic striking rod to extend and retract.
[0019] The beneficial effects of this utility model are:
[0020] This utility model's yarn feeding drum mechanism features a sorting blocking component that can move up and down on a sorting support. The velvety friction layer on the sorting blocking component increases friction, allowing it to block empty yarn tubes that haven't been fully unwound. This effectively prevents empty yarn tubes with a small amount of unwound yarn from breaking through the barrier and entering the rear of the equipment under conveying power, thus preventing the equipment from being affected by unwound yarn. When the empty yarn tubes are discharged from the yarn feeding drum and enter the conveyor belt on the conveyor platform, the conveyor belt moves the empty yarn tubes towards the sorting mechanism. The operator determines the height of the sorting blocking component in advance based on the size of the empty yarn tubes and finely adjusts the height of the sorting blocking component on the sorting support to improve the blocking effect. This allows fully unwound, smooth-surfaced empty tubes to pass through, while empty tubes with unwound yarn will be blocked due to their larger diameter and the increased friction from the height setting of the sorting blocking component and its velvety friction layer. This improves sorting accuracy and prevents empty tubes with a small amount of unwound yarn from being missed. Attached Figure Description

Detailed Implementation
[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] Example 1
[0029] A yarn-distributing drum 4 mechanism with sorting function, please refer to Figures 1-4 It includes a conveying platform 1 and a sorting mechanism 2, with the sorting mechanism 2 mounted on the conveying platform 1;
[0030] The sorting mechanism 2 includes a sorting bracket 21 and a sorting blocking member 22. The bottom of the sorting bracket 21 is fixedly set on the conveying platform 1 and is respectively set on both sides of the conveying platform 1. The sorting blocking member 22 can be lifted and connected between the sorting bracket 21. The outer surface of the sorting blocking member 22 is provided with a velvet friction layer 23.
[0031] The conveyor platform 1 is equipped with a conveyor belt 11, which is located between the sorting brackets 21 on both sides. The conveyor belt 11 is used to transport the empty tube of yarn from the yarn discharge cylinder 4 to the sorting blocking member 22.
[0032] The yarn feeding cylinder 4 mechanism of this utility model has a sorting blocking component 22 that can move up and down on the sorting bracket 21. The velvet friction layer 23 on the sorting blocking component 22 increases the friction force. When it comes into contact with the empty tube of unwound yarn, it can block the empty tube of yarn by means of friction force, effectively preventing the empty tube of yarn with a small amount of unwound yarn from breaking through the barrier and entering the rear end of the equipment under the conveying power, thereby preventing the equipment from being affected by the unwound yarn.
[0033] Specifically, when the empty yarn tube is discharged from the yarn discharge drum 4 and enters the conveyor belt 11 on the conveyor platform 1, the conveyor belt 11 moves to transport the empty yarn tube towards the sorting mechanism 2. The operator determines the height position of the sorting blocking member 22 in advance according to the size of the empty yarn tube. Usually, the height of the sorting blocking member 22 should be set to be equal to the diameter at the maximum diameter of the empty yarn tube. The sorting blocking member 22 is finely adjusted by raising and lowering it on the sorting bracket 21. The fine adjustment result should be such that even if only one layer of yarn is not unwound, the empty yarn tube can be effectively blocked, thereby ensuring the blocking effect and allowing the completely unwound, smooth-surfaced empty tube to pass through. Preferably, The sorting blocking member 22 can be plate-shaped or tubular. When the material of the empty yarn tube is brittle and not resistant to compression, a plate-shaped sorting blocking member 22 can be used, which can be blocked to one side without being excessively compressed. When the material of the empty yarn tube is hard and has a strong pressure resistance, a tubular sorting blocking member 22 can be used. The tubular sorting blocking member 22 has a better fit and can effectively increase the friction coefficient, thereby improving the blocking effect. Once there is an empty tube with unwound yarn, it will be blocked by the height setting of the sorting blocking member 22 and the increased friction force of its surface napped friction layer 23 due to its larger diameter, thereby improving the sorting accuracy and preventing the omission of empty tubes with a small amount of unwound yarn.
[0034] Example 2
[0035] This embodiment is based on Embodiment 1, please refer to it. Figures 1-2 The sorting bracket 21 is provided with a lifting guide groove, and the sorting blocking member 22 is slidably disposed in the lifting guide groove. Both ends of the sorting blocking member 22 are connected to the lifting drive mechanism 24. The lifting drive mechanism 24 can lift and lower the sorting blocking member 22, and can realize functions including height setting and height fine adjustment.
[0036] Preferably, the lifting drive mechanism 24 includes a lifting drive cylinder 241, which is vertically positioned on the side of the sorting bracket 21 away from the sorting barrier 22. The lifting drive cylinder 241 is connected to a cylinder piston rod 242, the end of which is fixedly connected to the end of the sorting barrier 22. Using the lifting drive cylinder 241 allows for stepless height adjustment, enabling the sorting barrier 22 to be fixed at any height, thus achieving better fine-tuning.
[0037] Example 3
[0038] This embodiment is based on Embodiment 1, please refer to it. Figure 3 , Figure 4 Multiple transport troughs 12 are evenly arranged on the surface of the conveyor belt 11; wherein, the transport trough 12 is a strip-shaped trough, the bottom surface of the transport trough 12 is arc-shaped, the width of the transport trough 12 is set to be greater than or equal to the diameter of the empty tube of yarn, and the length direction of the transport trough 12 is parallel to the setting direction of the sorting blocking member 22.
[0039] The use of arranged transport troughs 12 to transport empty yarn tubes in an orderly manner can make the overall transport and sorting more orderly. When the yarn tube in front of it is blocked, the empty yarn tube behind it is placed in the transport trough 12 behind it. After the blocked empty yarn tube is sorted and discharged, the empty yarn tube behind it can also pass smoothly through the sorting blocking member 22.
[0040] Example 4
[0041] This embodiment is based on Embodiment 1, please refer to it. Figures 2-4 The sorting blocking member 22 is set as a blocking side and a passing side on both sides of the conveyor belt 11 in the conveying direction. The blocking side of the sorting blocking member 22 on the conveying platform 1 is provided with a sorting discharge mechanism 3. The sorting discharge mechanism 3 is used to discharge the empty tube of the yarn blocked by the sorting blocking member 22 to the conveying platform 1.
[0042] Preferably, the sorting and discharge mechanism 3 includes a discharge drive base 31 disposed on one side of the conveyor platform 1 and a telescopic striking rod 32 connected to the discharge drive base 31. The telescopic striking rod 32 is connected to the end of the discharge drive base 31 facing the conveyor belt 11. The drive base is equipped with a hydraulic drive mechanism or a pneumatic drive mechanism, which are used to provide power for the telescopic striking rod 32 to extend and retract.
[0043] In a preferred embodiment, a sorting hopper is provided on the conveying platform 1 on the opposite side of the sorting and discharge mechanism 3. The sorting hopper can collect the empty tubes of the sorted yarn and concentrate them in a storage container for subsequent unified processing.
[0044] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
