Description

Technical Field

[0001] This utility model belongs to the field of conical object distribution technology, and in particular relates to a conical object detection and distribution mechanism. Background Technology

[0002] In the textile industry, yarn delivered by spinning mills is wound into thin-walled, lightweight, conical "paper yarn cones" (hereinafter referred to as conical objects) to become packaged yarn, which is then delivered to yarn dyeing companies. After the yarn dyeing companies "turn" the packaged yarn delivered by the spinning mills, the paper conical objects can be recycled and reused. Before recycling, each conical object must be inspected for its integrity; only those with intact surfaces are recycled.

[0003] Furthermore, in the textile yarn manufacturing industry, pagoda-shaped yarn products extensively utilize injection-molded thin-walled, lightweight conical cores. During injection molding, moisture in the plastic raw material or the presence of impurities can cause defects in the conical cores as the liquid plastic solidifies, rendering them unusable. Given the vast volume of pagoda-shaped yarn used, manual inspection is an extremely labor-intensive task, resulting in low efficiency in the overall identification and recycling of these conical objects. Utility Model Content

[0004] This utility model provides a conical object detection and distribution mechanism, which is implemented as follows: A conical object detection and distribution mechanism includes:

[0005] The support mechanism is equipped with a distribution component and a conveying mechanism. The conveying mechanism is suspended above the distribution component. The conical object delivered by the conveying mechanism falls into the distribution component. The distribution component rotates and respectively dispenses the good product conveying pipe and the defective product output pipe located on the outer periphery of the support mechanism.

[0006] The distribution component includes a turntable, a circular array of cups distributed on the turntable, and a gripper unit located below the turntable. The support mechanism has four sets of points: a loading point, a detection point, a defective product unloading point, and a good product unloading point. The gripper unit is located below the cups. When the cups rotate to the loading point, the gripper unit below the cups will clamp the conical object that falls into the cups. Then the turntable rotates to the detection point. After the detection is completed, the cups pass through the defective product unloading point and the good product unloading point in sequence. Based on the detection results, the materials are distributed and unloaded at the defective product unloading point and the good product unloading point.

[0007] Preferably, the gripper unit includes a connecting plate, a push plate, and a spring. The middle section of the connecting plate is rotatably connected to a rotating shaft on the turntable. The push plate is disposed at one end of the connecting plate. A spring is disposed at the end of the connecting plate away from the push plate. The other end of the spring is fixedly connected to the turntable.

[0008] The connecting plate is provided with a first clamping plate, and the turntable is provided with a second clamping plate. Under the deflection and traction of the connecting plate, the first clamping plate moves away from or closer to the second clamping plate. The change in distance between the first clamping plate and the second clamping plate completes the clamping of the conical object. When the push plate is subjected to force, the connecting plate rotates around the axis of rotation, the first clamping plate moves away from the second clamping plate, the clamping area expands, and the first clamping plate loses contact with the conical object. After the force on the push plate is released, the spring re-pulls the connecting plate to rotate, and the first clamping plate resumes contact with the second clamping plate.

[0009] Preferably, a third pusher, a second pusher, and a first pusher are respectively provided at the loading point, the defective product unloading point, and the good product unloading point. The third pusher, the second pusher, and the first pusher push the gripper unit that arrives at the location to complete the gripping or releasing of the conical object.

[0011] Preferably, the support mechanism includes a support plate and a lower support. The support plate is assembled on the top of the lower support. The outer side of the lower support is provided with a first push rod frame, a detection table support, a second push rod frame, and a third push rod frame. The third push plug, the second push plug, and the first push plug are respectively assembled on the first push rod frame, the second push rod frame, and the third push rod frame. The detection table support is provided with a detection camera assembly. Below the first push rod frame, there is also a tray for supporting the conical object. When loading, the conical object placed by the material conveying mechanism will be blocked by the tray. The gripper unit can clamp the conical object that is resting on the tray for subsequent transfer.

[0012] Preferably, the testing platform support is also provided with an auxiliary testing light source. The testing camera assembly is based on the principle that when light is projected onto the small end of the defective cone along the longitudinal axis, the area of ​​the visible white light projection is larger than the area of ​​a circular white light on the intact small end of the cone, that is, larger than the benchmark reference value stored in the vision system.

[0013] Preferably, the good product conveying pipe and the defective product output pipe are respectively located below the first push plug and the second push plug.

[0014] Preferably, a reduction motor is provided at the center of the lower support, and the reduction motor is connected to the bearing plate by bolts. The motor shaft of the reduction motor passes through the bearing plate and is connected to the turntable.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] This utility model embodiment provides a conical object detection and distribution mechanism, such as... Figures 1-8 As shown, the conical object detection and distribution mechanism includes:

[0031] The support mechanism 30 includes a distribution component 20 and a conveying mechanism 10. The conveying mechanism 10 is suspended above the distribution component 20. The support mechanism 30 has four sets of points: a loading point, a detection point, a defective product unloading point, and a good product unloading point. The conical object 60 delivered by the conveying mechanism 10 falls into the distribution component 20 at the loading point. The distribution component 20 then pulls the conical object 60 through the detection point, the defective product unloading point, and the good product unloading point one by one. The support mechanism 30 has a good product conveying pipe 41 and a defective product output pipe 42 below the good product unloading point and the defective product unloading point, respectively, for the recovery of good and defective products. An detection camera assembly 50 is provided above the detection point.

[0032] After completing the detection work at the detection point, the distribution component 20 will release the conical object 60 at the defective product unloading point or the good product unloading point according to the detection results. After the release is completed, the distribution component 20 returns to the loading point to reload the conical object 60.

[0033] The support mechanism 30 includes a support plate 31 and a lower support 32. The support plate 31 is equipped with a reduction motor 23 for driving the distribution component 20 to rotate. The reduction motor 23 is bolted to the support plate 31. The motor shaft of the reduction motor 23 passes through the support plate 31 and is connected to the turntable 21. The material conveying mechanism 10 is connected to the lower support 32.

[0034] The distribution component 20 includes a turntable 21, a collection cup 22 arranged in a ring array on the turntable 21, and a gripper unit 24 located below the turntable 21. The gripper unit 24 is located below the collection cup 22. When the collection cup 22 rotates to the loading point, the gripper unit 24 located below the collection cup 22 will grip the conical object that falls into the collection cup 22. Then the turntable 21 rotates to the detection point. After the detection is completed, the collection cup 22 passes through the defective product unloading point and the good product unloading point in sequence. According to the detection results, the material is distributed and unloaded at the defective product unloading point and the good product unloading point.

[0035] The gripper unit 24 includes a connecting plate 242, a push plate 243, and a spring 245. The middle section of the connecting plate 242 is rotatably connected to the rotating shaft 241 provided on the turntable 21. The push plate 243 is provided at one end of the connecting plate 242. The end of the connecting plate 242 away from the push plate 243 is provided with a spring 245. The other end of the spring 245 is fixedly connected to the turntable 21.

[0036] The connecting plate 242 is provided with a first clamping plate 244, and the turntable 21 is provided with a second clamping plate 246. The first clamping plate 244 moves away from or closer to the second clamping plate 246 under the deflection and traction of the connecting plate 242. The change in distance between the first clamping plate 244 and the second clamping plate 246 completes the clamping of the conical object 60. The first clamping plate 244 and the second clamping plate 246 are arc-shaped plate structures. The first clamping plate 244 and the second clamping plate 246 contact each other to form a ring structure and construct a circular clamping area. The first clamping plate 244 and the second clamping plate 246 will clamp on the outer wall of the conical object 60, thereby realizing the transfer of the conical object 60.

[0037] When the push plate 243 is subjected to force, the connecting plate 242 rotates around the pivot 241, the first clamping plate 244 moves away from the second clamping plate 246, the clamping area expands, the first clamping plate 244 loses contact with the conical object 60, after the force on the push plate 243 is released, the spring 245 pulls the connecting plate 242 to rotate again, and the first clamping plate 244 resumes contact with the second clamping plate 246.

[0038] In a preferred embodiment of this invention, a third pusher, a second pusher 302, and a first pusher 301 are respectively provided at the loading point, the defective product unloading point, and the good product unloading point. The third pusher, the second pusher 302, and the first pusher 301 push the gripper unit 24 that reaches that location, thereby clamping or releasing the conical object 60. The third pusher, the second pusher 302, and the first pusher 301 have the same structure. Taking the first pusher 301 at the good product unloading point as an example, the first pusher 301 adopts a pneumatic push rod principle. The first pusher 301 can act on the pusher plate 243 by extending its own length. Due to the force of the first pusher 301, the pusher plate 243 is subjected to force. As the end of the connecting plate 242 where the pusher plate 243 is located is subjected to force, the connecting plate 242 will deflect around the pivot 241, and the first clamping plate 244 located on the connecting plate 242 will move away from the second clamping plate 246. The third pusher, the second pusher 302 and the first pusher 301 are respectively fixedly supported by the first push rod frame 332, the second push rod frame 334 and the third push rod frame 335 provided on the outside of the lower bracket 32.

[0039] In this embodiment, the rotating shaft 241 is a fixed shaft, and the middle section of the connecting plate 242 is provided with a shaft hole adapted to the rotating shaft 241, such as... Figure 8 As shown, the turntable 21 is provided with a connecting seat 247 with a through hole for fixing the spring 245. Figure 8For ease of demonstration, the spring 245 is not directly nested on the connecting seat 247. In reality, the collar at the end of the spring 245 needs to pass through the through hole structure on the connecting seat 247. The connecting plate 242 and the push plate 243 are arranged vertically. The first clamping plate 244 is located on the side of the rotating shaft 241 away from the spring 245. The second clamping plate 246 is fixedly set on the turntable 21. The number of the gripper units 24 is four sets and they are arranged in an array.

[0040] The material cup 22 adopts an inverted hollow frustum structure to help position the conical object 60. The material cup 22 is connected to the feeding port on the turntable 21. The conical object 60 passes through the feeding port and reaches the lower end face of the turntable 21 through the turntable 21. The gripper unit 24 blocks the conical object 60. Since the diameter of the feeding port is larger than the diameter of the conical object 60, a support plate 331 for supporting the conical object 60 is also provided below the first push rod frame 332. When loading, the conical object 60 put in by the feeding mechanism 10 will be blocked by the support plate 331. The gripper unit 24 can clamp the conical object 60 that is stopped on the support plate 331 for subsequent transfer.

[0041] In a preferred embodiment of this invention, the material conveying mechanism 10 includes a vertical rod 11, a main feed pipe 12, and a separation pipe 13; the vertical rod 11 is a right-angle structure and is connected to a material conveying mechanism support 336 provided on the lower support 32; the main feed pipe 12 and the separation pipe 13 are connected to the vertical rod 11 by a retaining ring.

[0042] In this embodiment, a blocking gripper 14 and a clamping plate 16 are provided at the connection between the feed main pipe 12 and the separation pipe 13. A gate 15 is provided at the end of the separation pipe 13. Here, the conical object 60 enters the conveying mechanism 10 from the feed main pipe 12. After reaching the gate 15, the blocking gripper 14 clamps the conical object 60 following the conical object 60 in the separation pipe 13, preventing the subsequent conical object 60 from falling further. Then, the gate 15 is opened, allowing the conical object 60 in the separation pipe 13 to fall into the material cup 22 located at the loading point and be clamped by the gripper unit 24 located below the material cup 22. After the conical object 60 is delivered, the gate 15 is closed and the blocking gripper 14 is opened to allow the next group of conical objects 60 to reach the separation pipe 13. A photoelectric actuation sensor is provided at the end of the separation pipe 13 to sense the state of the conical object 60 arriving at and leaving the separation pipe 13.

[0043] The clamping plate 16 is composed of a U-shaped plate and a base plate, both with through holes. The base plate is connected to the top of the separation tube 13, and the U-shaped plate is connected to the end of the feed main tube 12. The through holes allow the conical object 60 to pass through the U-shaped plate and the base plate. The two ends of the U-shaped plate are connected to the base plate to form a spacer cavity. The blocking claw 14 extends into the spacer cavity. When there is a conical object 60 in the separation tube 13, the next set of conical objects 60 will stay in the spacer cavity. The blocking claw 14 clamps the conical object 60 located in the spacer cavity. After the gate 15 is opened, although the conical object 60 located in the spacer cavity loses the support of the conical object 60 located in the separation tube 13, it will not fall directly into the separation tube 13 due to the clamping of the blocking claw 14. The conical object 60 needs to be placed into the feed main tube 12 with the small end facing down.

[0044] In a preferred embodiment of this invention, the lower support 32 is provided with a detection platform support 333 for supporting the detection camera assembly 50. The detection platform support 333 is also provided with an auxiliary detection light source. By illuminating the conical object 60 with the light source, the detection camera assembly 50 suspended above the light source can easily collect corresponding image information. In the attached figure, the detection camera assembly 50 is fixed by existing fixing rods. The attached figure shows the initial setting position of the detection camera assembly 50. During the inspection process, the camera lens needs to be aimed at the material cup 22 located at the detection point.

[0045] In this embodiment, the conical object 60 is a thin-walled object, and the inner diameter of the large and small ends of the intact conical object 60 is fixed. When light is projected along the longitudinal axis of the conical object 60 from the small end to the large end, viewed from the side of the large end, it appears as a circular white light surrounded by a circular black ring; the black ring is formed by the wall of the conical object 60 blocking the light rays projected from the small end to the conical object 60; the reverse is also true. With a fixed inner diameter at the intact small end, the shape of the light rays projected onto the small end, viewed from the large end, is a circular white light of a fixed diameter; with a non-incomplete small end, the shape of the light rays projected onto the small end, viewed from the large end, is the projected shape of the non-incomplete small end.

[0046] The vision system captures a circular white light image of the small end of a good quality conical object, calculates the statistics of the circular white light image, and stores it in the vision system as a reference value for the white light image.

[0047] As described above, the defects in the conical object 60 occur during the manufacturing process or are damaged during use, and the defects are concentrated at the small end. The defects are either missing material or chipped. When light is projected onto the small end along the longitudinal axis of the conical object 60, the area of ​​the visible white light projection is larger than the area of ​​a circular patch of white light on the intact small end of the conical object 60, that is, larger than the reference value stored in the visual system.

[0048] When each conical object 60 briefly pauses at the second position, the light source 25 projects from the small end of the conical object 60 to the large end. Viewed from the large end towards the small end, a conical object 60 with an intact small end appears as a white light patch surrounded by a circular black ring; a conical object 60 with an incomplete small end appears as a non-circular white light patch surrounded by a circular black ring. When the conical object 60 pauses at the second position, the vision camera focuses on the small end of the conical object 60, capturing a planar image of the conical object 60 at that point. The vision system automatically calculates the area of ​​the white light captured by the camera and compares the captured image with a pre-stored reference value in the vision system. If the statistical count of the captured white light area is within the preset deviation value of the reference value, the conical object 60 is judged as good; if the statistical count of the captured white light area is outside the preset deviation value of the reference value, the conical object 60 is judged as bad. The corresponding image recognition system software uses existing recognition algorithms.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
