Description

Technical Field

[0001] The utility model relates to the technical field of bobbin yarn turning and conveying devices, in particular to a bobbin yarn turning and conveying mechanism. Background Art

[0002] A bobbin, also known as a yarn cone, is a narrow, wide tube formed by winding yarn onto a reel. During the production process, the yarn is transported between various production steps. When a standing bobbin is transported uphill, it inevitably shakes or even falls over, making it difficult to detect. To address this, the standing bobbin can be flipped horizontally to avoid these problems. This requires the use of a flipping device. At present, most of the bobbin flipping devices have complex structures. For example, the Chinese utility model patent is named a bobbin fast flipping device, and the application number is 2022222443929. The patent sets upper and lower linked conveying rollers between two vertically arranged guide rods with a spacing. The upper and lower conveying rollers are used to clamp the bobbin yarn. The conveying rollers are connected by a transmission assembly. The flipping motor drives the two flipping shafts, which respectively link the upper and lower conveying rollers to clamp the upper and lower ends of the bobbin yarn and then flip it. Although it is a 180° flip, many components are set between the upper and lower conveying rollers, such as a mounting plate, a guide sleeve, etc., and the driving conveying mechanism is also used to drive the flipping mechanism to move. The entire structure is highly complex. Utility Model Content

[0023] The utility model provides the following technical solutions: Figures 1 to 4 As shown, a bobbin turning and conveying mechanism comprises a frame 1 and a conveying mechanism located at the top of the frame 1.

[0024] A flip mechanism is provided at the end of the conveying mechanism, and the flip mechanism includes a flip roller 2, a rotating shaft 3 inserted into the flip roller 2, a servo motor assembly driving the rotating shaft 3 to rotate, two flip plates 4 fixed on the rotating shaft 3, and a first photoelectric sensor 13;

[0025] The two ends of the rotating shaft 3 are fixed to the frame 1, with a bearing disposed between the rotating shaft 3 and the reversing drum 2. Two reversing plates 4 are symmetrically disposed at the ends of the reversing drum 2. Each reversing plate 4 has a central hole into which the rotating shaft 3 is inserted. Four rotating lobes extend radially outward from the reversing plates 4 along the rotating shaft. Two adjacent rotating lobes are arranged perpendicularly, with the two vertical lobes and the two horizontal lobes mirror-symmetrically disposed about the central hole. The rotating lobes are rectangular, with their dividing lines offset from the central hole, and an arc-shaped transition section is disposed between adjacent lobes. The servo motor assembly is fixed to the frame 1, and the first photoelectric sensor 5 is disposed adjacent to the reversing plates 4 and fixed to the inner side of the frame 1. The two reversing plates 4 are located at either end of the reversing drum 2, with a spacing therebetween. The reversing plates 4 are fixed to the rotating shaft 3, with a bearing disposed between the rotating shaft 3 and the reversing drum 2, allowing relative rotation between the rotating shaft 3 and the reversing drum 2.

[0026] The conveying mechanism includes a conveyor belt 6, a driving wheel 7, a driving motor, and two adjustable guardrails located on both sides of the conveyor belt 6. One end of the conveyor belt 6 is mounted on the driving wheel 7, and the other end is mounted on the flip roller 2. The driving wheel 7 and the driving motor are fixed to the frame 1. The adjustable guardrails are composed of guardrail plates 8 and a base 9 fixed to the top of the frame. The guardrail plates 8 are movably connected to the base 9 by bolts. The conveyor belt 6 is a narrow belt. The bobbin yarn is transported standing on this narrow belt. The adjustable guardrails at both ends of the conveyor belt 6 can keep the bobbin yarn in the middle position of the conveyor belt 6. A second photoelectric sensor 10 is installed on both sides of the conveyor belt 6 to control the bobbin yarn stop position. The driven end of the conveying mechanism is the flip roller 2.

[0027] A second photoelectric sensor 10 is fixed on the middle part of the guardrail plate 8 and adjacent to the turnover mechanism for detecting the stroke of the bobbin.

[0028] The servo motor assembly includes a servo motor 11, a driving pulley, a belt, a driven pulley fixed on the output shaft of the servo motor 11, and a box 12 fixed on the side wall of the frame. The driving pulley is connected to the driven pulley through the belt, and the driven pulley is fixed to the end of the rotating shaft 3. The driving pulley, belt, and driven pulley are all located in the box, and the servo motor 11 is fixed on the box 12.

[0029] Working principle: When the standing bobbin moves forward with the conveyor belt until it approaches the end of the conveyor belt 6, the second sensor 10 on the guardrail plate 8 is triggered. At this time, the bobbin stops, and the servo motor 11 receives the signal and drives the rotating shaft 3 through the belt, causing the flip plate 4 to rotate to the position that triggers the first photoelectric sensor 5. That is, a horizontal rotating blade is at the same horizontal position as the conveyor belt 6, and the flip plate 4 stops rotating. The conveying mechanism receives the signal, and the conveyor belt 6 rotates, driving the bobbin to continue forward until it moves to the horizontal rotating blade. At this time, the bobbin triggers the first photoelectric sensor 5 here. The servo motor 11 controls the movement of the rotating shaft 3, thereby driving the flip plate 4 to rotate, flipping the standing bobbin 90° to become a horizontal bobbin. This action is completed in one go.
