Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a bobbin yarn turning device with a roller. Background Art

[0002] With the development of the times, automation equipment is constantly developing and popularizing, and all walks of life are moving towards automation and intelligence. Spinning mills have achieved automated operation in processes such as cleaning and winding, and the final link, namely, the conveying and packaging of bobbins, is moving towards automation. Cone conveying and packaging is the process of coating, bagging and transporting the bobbins produced by the winding machine to a designated area. For the convenience of transportation, the bagged bobbins need to be arranged as neatly as possible, and the shape of the bobbins is a truncated cone with different upper and lower diameters. Therefore, before bagging, the bobbins need to be turned over so that they can be arranged with the thick and thin ends facing down. The bobbin turning device is a mechanism that completes the turning of the bobbins so that the thick end faces down and the thin end faces down.

[0003] Application No. 202221705496.9 discloses an automatic bobbin turning device, in which the clamping member that clamps the bobbin clamps the bobbin under the action of a power push rod. The impact generated and the pressure of the power push rod directly contact the bobbin, and the protection of the bobbin is not perfect.

[0004] Application No. 201821625815.9 discloses a bobbin clamping, flipping and lifting device. Although the clamping plate of the device has added a spring to buffer the impact force when clamping the bobbin, the steel clamping plate will still clamp the bobbin under a certain force, and long-term clamping may damage the bobbin.

[0005] Application No. 202120503734.7 discloses a bobbin turning device, which has the following disadvantages: 1. The clamping part has a single cylinder to drive the yarn holding part on one side to contract, and the yarn holding part on the other side is driven by a gear rack. When the clamping force is large or the contraction speed is fast, tooth jumping may occur, resulting in the contraction action of the yarn holding devices on both sides being asynchronous and causing the bobbin to shift. Accumulated tooth jumping may even lead to a failure in clamping and turning; 2. The yarn holding device directly contacts the bobbin yarn with a conical tube. Although the conical tube fits the outer surface of the bobbin yarn as closely as possible, it will still squeeze the soft yarn. Long-term clamping or excessive clamping force may cause the bobbin yarn to loosen and deform or even damage the yarn. Utility Model Content

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0046] like Figures 1 to 5 As shown, the utility model provides a bobbin turning device with a roller, comprising: a bobbin conveying mechanism 1, used for conveying the bobbin; a rotating mechanism 4, used for turning the bobbin, the inner diameter of the rotating drum 41 is larger than the outer diameter of the large end of the bobbin to avoid the rotating drum from clamping the bobbin, the large end of the bobbin is the thick end of the bobbin; a clamping mechanism 3, used for bringing the two parts of the rotating mechanism 4 closer to each other, the rotating drum 41 clamping the bobbin; a lifting mechanism 2, used for lifting the clamping mechanism 3 to a certain height, thereby lifting the rotating drum 41.

[0047] The bobbin conveying mechanism 1 is responsible for conveying the bobbin outputted by the winding machine or other production equipment to the working position of the turning device, ensuring that the bobbin can be accurately placed in the rotating mechanism 4, ready for the turning operation.

[0048] The rotating mechanism 4 includes: a rotating drum 41, a rotating cylinder 42 and a positioning mechanism 44; the rotating cylinder 42 drives the rotating drum 41 to rotate to a certain angle, and the rotating drum 41 after being rotated into position is positioned by the positioning mechanism 44. The rotating drum 41 clamps the bobbin yarn, and the driving force of the rotating cylinder 42 rotates the bobbin yarn 180 degrees, completing the conversion from the thin end upward to the thick end upward.

[0049] The rotary cylinder 42 provides driving force for the rotary mechanism 4, drives the main rotary drum 411 to rotate, and indirectly drives the slave rotary drum 412 to complete the turning of the bobbin. The design of the turning mechanism is simplified, the problem of tooth skipping or asynchronism that may occur in the conventional turning process using a gear mechanism is avoided, and the stability and efficiency of the turning are improved.

[0050] The rotating drum 41 is composed of two half drums, including a main rotating drum 411 and a slave rotating drum 412; the main rotating drum 411 is set on the clamping bracket 34 on one side through a rotating cylinder 42; the slave rotating drum 412 is set on the clamping bracket 34 on the other side through a rotating shaft 43; the positioning mechanism 44 is used to position the slave rotating drum 412. Openings 45 are set on the two end surfaces of the main rotating drum 411 and the slave rotating drum 412 for drum positioning of the bobbin; the stability and accuracy of the bobbin during the flipping process are ensured, the sliding or tilting of the bobbin during the flipping process is avoided, and the flipping efficiency is improved.

[0051] The main rotary drum 411 and the slave rotary drum 412 are used to wrap the bobbin yarn in the rotary drum 41. The main rotary drum 411 and the slave rotary drum 412 are combined to form a cylindrical rotary drum. The inner diameter of the rotary drum 41 is larger than the maximum diameter of the bobbin yarn, that is, the outer diameter of the large end of the bobbin yarn. The bobbin yarn is clamped without contacting the yarn. The openings on the upper and lower end surfaces of the rotary drum position and fix the drum of the bobbin yarn to flip it, avoiding the drum from directly contacting the bobbin yarn and reducing damage to the bobbin yarn.

[0052] The clamping mechanism 3 includes: a clamping cylinder 33, a linear guide rail 32 and a clamping bracket 34; the clamping cylinder 33 pulls the clamping bracket 34 to move on the linear guide rail 32. The clamping mechanism 3 also includes: a base 31; the linear guide rail 32 and the clamping cylinder 33 are arranged on the base 31.

[0053] The clamping cylinder 33 controls the movement of the clamping bracket 34 through the linear guide 32, and the linear guide 32 guides the movement of the clamping bracket 34 to ensure the smoothness and accuracy of the action of the clamping cylinder 33, and realize the precise movement of the position of the rotating mechanism 4, so that the main rotating drum 411 and the slave rotating drum 412 of the rotating mechanism 4 clamp the bobbin. It ensures that the bobbin will not slide or tilt during the flipping process, improves the stability of the flipping, and protects the bobbin from damage.

[0054] The lifting mechanism 2 includes: a lifting cylinder 21 and a mounting plate 22. The lifting cylinder 21 is arranged on the mounting plate 22. The cylinder rod is connected to the clamping mechanism 3. Specifically, the cylinder rod is connected to the base 31 of the clamping mechanism 3 for lifting and lowering the clamping mechanism 3.

[0055] After the main rotary drum 411 and the slave rotary drum 412 clamp the bobbin, the lifting mechanism 2 works to lift the clamping mechanism 3 and the rotating mechanism 4, and then the rotating mechanism 4 rotates to prevent the bobbin from colliding with the conveying mechanism.

[0056] The positioning mechanism 44 includes a first shell 441, a second shell 443, a spring 442, a roller 446 and a roller shaft 445; a spring 442 is provided between the first shell 441 and the second shell 443, a roller shaft 445 is provided at one end of the second shell 443, and the roller 446 is rotatably provided on the roller shaft 445; a bearing 444 is provided between the roller 446 and the roller shaft 445. A positioning hole 46 is provided on the secondary rotating drum 412, and the roller 446 rolls into the positioning hole 46 to position the secondary rotating drum 412. The first shell 441 is mounted on a clamping bracket on one side of the secondary rotating drum. During the rotation of the secondary rotating drum, the roller rotates on one side of the secondary rotating drum. When the roller rolls into the positioning hole 46, the secondary rotating drum is positioned. Figure 3 As shown, the diameter of the positioning hole 46 is smaller than the diameter of the roller, and the roller forms a card point positioning after reaching the positioning hole under the elastic force of the spring.

[0057] The positioning mechanism 44 ensures that the rotating drum 41 remains in the correct position after the turning is completed, preventing the bobbin from shifting in subsequent operations, while reducing the number of driving cylinders and reducing costs. The roller 446 is inserted into the positioning hole 46, realizing the precise positioning of the rotating drum 412, improving the synchronization and accuracy of the entire turning process.

[0058] The bobbins are continuously transported on the conveying mechanism, with the large end (thick end) of the bobbins facing downwards and the small end (thin end) facing upwards. In order to ensure stability and save space after subsequent packaging, some bobbins need to be arranged at intervals with the large end (thick end) facing upwards and the small end (thin end) facing downwards.

[0059] The working method is as follows: in the first step, the main rotating drum 411 and the slave rotating drum 412 are driven by the clamping mechanism 3 to move toward the center to clamp the bobbin yarn, and the drum of the bobbin yarn is exposed from the openings 45 at both ends of the rotating drum 412 to fix the bobbin yarn in the rotating drum 41; in the second step, the lifting cylinder 21 lifts the clamping mechanism 3, thereby lifting the rotating drum 41; in the third step, the rotating cylinder 42 drives the rotating drum 41 to rotate 180 degrees; in the fourth step, the lifting cylinder 21 lowers the clamping mechanism 3, thereby lowering the rotating drum 41; in the fifth step, the main rotating drum 411 and the slave rotating drum 412 are opened under the drive of the clamping mechanism 3, and the bobbin yarn is flipped.

[0060] Since the rotary cylinder 42 is used for flipping, one flip is completed by rotating 180 degrees clockwise, and the next flip is completed by rotating 180 degrees counterclockwise. No reset is required, which increases the continuity of the action and improves efficiency.

[0061] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
