[0002] As a labor-intensive industry, the textile sector faces labor shortages due to my country's economic development and industrial upgrading. Therefore, automating existing equipment in the textile industry is of great significance. The winding process, a crucial link in the textile industry, requires a huge workforce. A single winding machine typically needs 3-5 yarn inserters to complete daily production. These workers repeatedly perform mechanical actions such as picking up yarn bobbins, extracting yarn ends, and placing them into the yarn storage. However, winding workshops generally suffer from high noise pollution and a large amount of short fibers in the air, posing a threat to worker health. Therefore, intelligent transformation of winding workshops to improve the working environment and reduce labor pressure in textile factories is urgently needed.

[0036] One embodiment of this application provides a feeding device for conveying and sorting materials. Specifically, in the following embodiment, the material conveyed and sorted by the feeding device is a tube yarn. The tube yarn has a cylindrical structure, and the outer diameter of the tube yarn gradually decreases from one axial end to the other axial end, forming a large end and a small end with unequal outer diameters.

[0037] like Figures 1 to 3 As shown, the feeding equipment includes a lifting device 100 and a distributing device 200. The lifting device 100 is used to convey materials from bottom to top and identify the appearance characteristics of the yarn tube to generate an identification signal. The distributing device 200 is located on one side of the lifting device 100 and is used to distinguish materials based on the identification signal generated by the identification result.

[0038] The lifting device 100 includes a fixed frame 110 and a lifting mechanism 120. The fixed frame 110 is supported on the ground or other mounting surface, mainly serving a fixing and supporting function. Specifically, the fixed frame 110 has a frame structure formed by metal components, and the length direction of the fixed frame 110 is the first direction (i.e., Figure 1 The width direction of the fixed frame 110 is the second direction (i.e., the X direction in the X direction), and the width direction of the fixed frame 110 is the second direction (i.e., the X direction in the X direction). Figure 1 The Y-direction of the fixed frame 110 is the third direction (i.e., the height direction of the frame 110 is the third direction). Figure 1 (in the Z direction). The right side of the fixed frame 110 mentioned below is... Figure 1 On the right side of the fixed frame 110, the left side is... Figure 1 On the left side of the middle. The lifting mechanism 120 is installed on the fixed frame 110 to receive the bobbin conveyed by the upstream feeding device and to convey the bobbin from bottom to top to the downstream distribution device 200.

[0039] Please see Figure 1 , Figure 3 as well as Figure 4 The lifting mechanism 120 includes a fixed plate 121, a drive wheel unit 1221, a driven wheel unit 1223, a lifting conveyor chain 123, and multiple lifting units 125.

[0040] Specifically, the fixing plate 121 is a long strip-shaped structure, fixed within the fixing frame 110. The fixing plate 121 extends from the bottom of the fixing frame 110 along a third direction to the top of the fixing frame 110. The width direction of the fixing plate 121 is parallel to the first direction, and the thickness direction of the fixing plate 121 is parallel to the second direction. The driving wheel unit 1221 is installed on the top of the fixing frame 110 and located on one side of the fixing plate 121 in the thickness direction. The driven wheel unit 1223 is installed on the bottom of the fixing frame 110 and located on the same side of the fixing plate 121 as the driving wheel unit 1221. Two lifting conveyor chains 123 are spaced apart along the first direction on opposite sides of the fixing plate 121. Each lifting conveyor chain 123 is wound around the driving wheel unit 1221 and the driven wheel unit 1223. The two lifting conveyor chains 123 and the fixing plate 121 together define a conveying surface for conveying the yarn tube on one side of the fixing frame 110 in the second direction. Multiple lifting units 125 are installed on the lifting conveyor chain 123 to limit and support the bobbins passing through the conveyor surface.

[0041] Thus, the bobbin can be supported on the lifting unit 125, and the central axis of the bobbin extends along the first direction. The lifting unit 125 can move upward along the fixed plate 121 in the third direction under the drive of the lifting conveyor chain 123 to lift the bobbin.

[0042] Furthermore, the lifting device 100 also includes multiple guide strips 150 made of materials such as metal wires. These guide strips 150 are spaced apart along a first direction. One end of each guide strip 150 is located on one side of the conveying surface and extends along the conveying direction of the conveying surface (i.e., a third direction). The other end of each guide strip 150 extends obliquely over the top of the conveying surface to above the material distribution device 200. Thus, the yarn conveyed to the top of the conveying surface can roll down along the guide strips 150 into the material distribution device 200.

[0043] To facilitate timely differentiation of yarn tubes by the material sorting device 200, the lifting device 100 also includes an image recognition unit 140. The image recognition unit 140 is mounted on the fixed frame 110, and its recognition area covers at least part of the conveying surface. The image recognition unit 140 is used to acquire images of the yarn tubes in the recognition area and generate recognition signals. The material sorting device 200 can differentiate the yarn tubes based on these recognition signals.

[0044] like Figure 4 and Figure 5As shown, the material distribution device 200 includes a mounting frame 210, a material distribution assembly 220, and a material discharge bin 240. The mounting frame 210 is fixed to the top of the fixed frame 110 of the lifting device 100 and is located on the side of the fixed frame 110 facing away from the conveying surface in the second direction. The material distribution assembly 220 is mounted on the mounting frame 210 and is located at the end of the guide bar 150. The material discharge bin 240 is located directly below the material distribution assembly 220. The top of the material discharge bin 240 has a discharge port facing the material distribution assembly 220, and the yarn tubes rolling down along the guide bar 150 fall onto the material distribution assembly 220.

[0045] The material distribution assembly 220 can rotate about a rotation axis extending in a first direction to switch between a first state, a second state, and a third state. When the material distribution assembly 220 is in the first state, it blocks one side of the material outlet in the first direction. One end of the yarn falling onto the material distribution assembly 220 is blocked, and the yarn falls into the material outlet 240 with the unblocked end facing downwards. When the material distribution assembly 220 is in the third state, it blocks the other side of the material outlet in the second direction. One end of the yarn falling onto the material distribution assembly 220 is blocked, and the yarn falls into the material outlet 240 with the unblocked end facing downwards. When the material distribution assembly 220 is in the second state, it blocks the material outlet, and the yarn cannot enter the material outlet 240 due to the obstruction of the material distribution assembly 220. Thus, based on the identification results of the lifting device 100, the material distribution component 220 can selectively switch to different states, so that the yarn tubes fall into the material drop hopper 240 in the same posture, while the waste material cannot enter the material drop hopper 240 due to the obstruction of the material distribution component 220.

[0046] The aforementioned material distribution device 200, through the rotation of the material distribution component 220, achieves the separation and rejection of waste yarns, with high separation efficiency and accuracy, thus improving the material distribution efficiency of the feeding equipment.

[0047] Furthermore, the material distribution device 200 also includes a waste bin 250, which is located below the material distribution assembly 220 and to one side of the discharge bin 240. The waste bin 250 has a waste outlet facing the material distribution assembly 220. When the material distribution assembly 220 switches from the second state to the third state, the yarn tubes on the material distribution assembly 220 can move to above the waste bin 250 under the drive of the material distribution assembly 220, and then fall into the waste bin 250 through the waste outlet. In this way, qualified yarn tubes enter the discharge bin 240, while waste is collected in the waste bin 250.

[0048] In a preferred embodiment, a detection unit is provided inside the waste bin 250. The detection unit is used to detect the quantity of yarn bobbins inside the waste bin 250 and issue a prompt when the bin is full. Specifically, in one embodiment, the detection unit is a photoelectric sensor, which can emit detection light to detect the quantity of yarn bobbins inside the waste bin 250.

[0049] Specifically, in some embodiments, the material distribution assembly 220 includes a baffle plate 221, a first material distribution plate 223, and a second material distribution plate 225. The baffle plate 221 is a generally rectangular plate structure, extending longitudinally along a first direction, and its length matches the length of the yarn tube. The first material distribution plate 223 and the second material distribution plate 225 are respectively disposed on opposite sides of the baffle plate 221 in the first direction, and are also located on opposite sides of the baffle plate 221 in the thickness direction of the baffle plate 221. Figure 5 As shown, the first material distribution plate 223 is located to the right of the baffle plate 221, and the second material distribution plate 225 is located to the left of the baffle plate 221.

[0050] When the material distribution assembly 220 is in the first state, the baffle plate 221 is in a vertical state with its thickness direction approximately parallel to the second direction. At this time, the first material distribution plate 223 is located above the discharge port to block one side of the discharge port in the first direction (i.e., Figure 5 (on the right side of the first material distribution plate 223), the second material distribution plate 225 is located on the side of the baffle plate 221 facing the waste bin 250. Thus, when the yarn tube falls with the small end on the right, the small end of the yarn tube is blocked by the first material distribution plate 223, and the large end of the yarn tube falls first, so that the yarn tube entering the waste bin 240 is in a vertical state with the large end facing down.

[0051] When the material distribution assembly 220 is in the third state, the baffle plate 221 is in a vertical state with its thickness direction approximately parallel to the second direction. At this time, the second material distribution plate 225 is located above the discharge port to block one side of the discharge port in the first direction, and the first material distribution plate 223 is located on the side of the baffle plate 221 facing the waste bin 250. Thus, when the yarn tube falls with its small end on the left, the small end of the yarn tube is blocked by the first material distribution plate 223, and the large end of the yarn tube falls first, so that the yarn tube entering the discharge bin 240 is in a vertical state with its large end facing down.

[0052] When the material distribution assembly 220 is in the second state, the baffle plate 221 is in a horizontal state with its thickness direction approximately parallel to the third direction. At this time, the first material distribution plate 223 and the second material distribution plate 225 are located on the upper and lower sides of the baffle plate 221, respectively. The baffle plate 221 blocks the material discharge port to prevent waste from falling. Then, the material distribution assembly 220 switches to the third state, and the waste follows the rotation of the material distribution assembly 220 to the side facing the waste bin 250. Under the action of gravity, the waste falls into the waste bin 250.

[0053] The material distribution device 200 also includes a material distribution drive component 230, which is mounted on the mounting frame 210. The output end of the material distribution drive component 230 protrudes above the material drop hopper 240 and is connected to the material distribution assembly 220 in a transmission manner. The material distribution assembly 220 rotates around the rotating shaft under the drive of the material distribution drive component 230, thereby switching between the first state, the second state, and the third state.

[0054] The material separating device 200 also includes a lifting and cutting assembly 260 and a material separating and cutting assembly 270. The lifting and cutting assembly 260 is located at the top of the conveying surface, and the material separating and cutting assembly 270 is located on one side of the material separating assembly 220. The lifting and cutting assembly 260 and the material separating and cutting assembly 270 are used to cut off the excess thread of the yarn tube. It is understood that the specific structure of the lifting and cutting assembly 260 and the material separating and cutting assembly 270 is not limited. In some embodiments, the lifting and cutting assembly 260 and the material separating and cutting assembly 270 are push-head shears.

[0055] The specific working process of the above-mentioned material distribution device 200 is as follows:

[0056] When the image recognition unit 140 of the lifting device 100 recognizes that the small end of the yarn tube is located on the right side of the fixed frame 110, before the yarn tube reaches the top of the conveying surface, the material distribution drive 230 drives the material distribution assembly 220 to rotate to the first state. At this time, the first material distribution plate 223 is located above and to the right of the discharge port. When the yarn tube rolls down along the guide bar 150 onto the material distribution assembly 220, the small end of the yarn tube abuts against the first material distribution plate 223, while the large end of the yarn tube falls downwards first. Therefore, the yarn tube falls into the discharge bin 240 with the large end facing downwards.

[0057] When the image recognition unit 140 of the lifting device 100 recognizes that the small end of the yarn tube is located on the left side of the fixed frame 110, before the yarn tube reaches the top of the conveying surface, the material distribution drive 230 drives the material distribution assembly 220 to rotate to the third state. At this time, the second material distribution plate 225 is located above the discharge port and to the left of the discharge port. When the yarn tube rolls down along the guide bar 150 onto the material distribution assembly 220, the small end of the yarn tube abuts against the second material distribution plate 225, while the large end of the yarn tube falls downwards first. Therefore, the yarn tube falls into the discharge bin 240 with the large end facing downwards.

[0058] When the image recognition unit 140 of the lifting device 100 identifies the yarn tube as waste, before the yarn tube reaches the top of the conveying surface, the material distribution drive 230 drives the material distribution assembly 220 to rotate to the second state. At this time, the baffle plate 221 is located above the drop port to block the drop port. When the yarn tube rolls down along the guide strip 150 onto the material distribution assembly 220, the yarn tube is supported on the baffle plate 221. Then, the material distribution drive 230 drives the material distribution assembly 220 to rotate to the third state. The yarn tube rotates under the action of the baffle plate 221 to above the waste bin 250, and finally falls into the waste bin 250 under the action of gravity.

[0059] The aforementioned lifting device 100 and feeding equipment can adjust the bobbin posture and remove waste materials by controlling the rotation of the material distribution component 220. The structure is simple and the control method is easy, which effectively improves the material distribution efficiency.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
