Description

Technical Field

[0001] This invention relates to the field of automated textile processing technology, and particularly to an identification and differentiation device and a feeding device. Background Technology

[0002] With socio-economic development and industrial upgrading, automating existing equipment in labor-intensive industries and replacing repetitive and tedious tasks with intelligent robots is of great significance. The textile industry, as one of the major labor-intensive industries, has high labor costs, especially in the winding process, a crucial link in the textile industry. A single winding machine requires 3-5 yarn inserters to complete daily production, with these workers performing repetitive mechanical actions such as picking up yarn tubes, extracting thread ends, and placing them into the yarn storage. Furthermore, winding workshops generally suffer from high noise pollution and a large amount of short fibers floating in the air, threatening workers' health. Therefore, intelligent transformation of winding workshops to improve production efficiency, improve the working environment, and reduce labor pressure has become an urgent problem to be solved.

[0003] However, as an important piece of equipment in the winding workshop, the yarn feeding equipment needs to distinguish between empty tubes and non-standard yarns and separate them from normal yarns. Therefore, how to design a device that can automatically separate different yarns is one of the challenges currently faced by those skilled in the art. Summary of the Invention

[0004] Therefore, it is necessary to provide an identification and differentiation device and a feeding device that can achieve the technical effect of automatically differentiating yarn tubes.

[0005] According to one aspect of this application, an identification and differentiation device is provided, comprising:

[0006] Identification cavity for containing materials;

[0007] A visual recognition mechanism, located on one side of the recognition cavity, is used to acquire an image of the material inside the recognition cavity and to obtain material characteristics based on the image;

[0008] A waste bin is located on one side of the recognition cavity, and a waste inlet is provided in the waste bin facing the top of the visual recognition mechanism;

[0009] A material feeding bin, located between the recognition cavity and the waste bin, has a material feeding inlet facing the top of the visual recognition mechanism; and

[0010] A material blocking mechanism is located between the identification cavity and the waste bin, and the material blocking mechanism is controlled to selectively connect the identification cavity to either the waste bin or the discharge bin.

[0011] In one embodiment, the material blocking mechanism includes:

[0012] A first baffle plate is located between the identification cavity and the discharge bin. The first baffle plate is controlled to move relative to the identification cavity to connect or block the identification cavity and the discharge bin.

[0013] A second baffle plate is located between the discharge bin and the waste bin. The second baffle plate is moved in a controlled manner relative to the waste bin to connect or block the discharge bin and the waste bin.

[0014] A material discharge gap is formed between the first baffle plate and the second baffle plate, which connects to the material discharge bin.

[0015] In one embodiment, the material blocking mechanism further includes a separating component located above the material discharge bin, the separating component being movable relative to the material discharge bin to extend into or out of the material discharge gap.

[0016] In one embodiment, the separating component includes a first separating member and a second separating member, one of which extends into or out of the material drop gap in a controlled manner.

[0017] In one embodiment, the identification and differentiation device further includes a feeding detection component, which is disposed on at least one side of the identification cavity and is used to detect whether there is material in the identification cavity.

[0018] In one embodiment, the identification and differentiation device further includes a clamping mechanism comprising two sets of clamping components located on opposite sides of the identification cavity. The two sets of clamping components are controlled to move closer or further apart to form a clamping gap for clamping material located within the identification cavity.

[0019] In one embodiment, the discharge bin includes a first discharge housing and a second discharge housing, which are arranged opposite each other in the horizontal direction and are capable of moving relative to each other in the horizontal direction to close or separate.

[0020] In one embodiment, the identification and differentiation device further includes a first material dropping drive and a second material dropping drive. The first material dropping drive is tractively connected to the first material dropping housing, and the second material dropping drive is tractively connected to the second material dropping housing. The first material dropping housing and the second material dropping housing move relative to each other in the horizontal direction under the drive of the first material dropping drive and the second material dropping drive.

[0021] In one embodiment, the identification and differentiation device further includes:

[0022] Material feeding guide rail;

[0023] The first material discharge slider is movably mounted on the material discharge guide rail and fixedly connected to the first material discharge housing; and

[0024] The second material discharge slider is movably mounted on the material discharge guide rail and fixed to the second material discharge housing.

[0025] According to another aspect of this application, a feeding device is provided, including the above-described identification and differentiation device.

[0026] The aforementioned identification and differentiation device uses a visual recognition mechanism to acquire images of the materials within the identification chamber and determine their characteristics based on these images. This allows the device to classify the materials as empty tubes, irregularly shaped yarns, or normal yarns. A material-blocking mechanism then directs empty tubes and irregularly shaped yarns into a waste bin, while normal yarns fall into a discharge bin. Therefore, this identification and differentiation device combines visual algorithms and mechanical mechanisms. Through the coordinated action of the visual recognition mechanism and the material-blocking mechanism, it efficiently and accurately removes empty tubes and irregularly shaped yarns from normal yarns, thus improving the efficiency of the feeding equipment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] like Figure 1 and Figure 2 As shown, one embodiment of the present invention provides a feeding device 100 for conveying and sorting materials. In the following embodiments, the feeding device 100 is applied in the winding process of the textile industry, and the material it lifts is a long tubular yarn 600, that is, a tubular yarn body obtained by winding fine yarn or roving on a hollow bobbin. The outer diameter of the yarn 600 gradually decreases from one end to the other, forming a large end and a small end with different outer diameters.

[0040] The feeding equipment 100 includes a lifting device 200 and an identification and differentiation device 400. The lifting device 200 is used to transport the bobbins from bottom to top. The identification and differentiation device 400 is used to identify empty bobbins, irregularly shaped bobbins, and the large and small ends of normal bobbins in the material. Based on the identification results, the device adjusts the posture of the normal bobbins 600, and finally removes the empty bobbins and irregularly shaped bobbins from the normal bobbins. The normal bobbins 600 are then dropped vertically to the downstream process with the large end facing down and the small end facing up.

[0041] Please continue reading. Figure 1 and Figure 2 The lifting device 200 includes a fixed frame 210, a lifting mechanism 230, and an ejection mechanism 24. The lifting mechanism 230 is mounted on the fixed frame 210 and forms a vertically upward-extending conveying channel to lift materials from bottom to top. The lifting and unloading mechanism is mounted on the fixed frame 210 and located at the top of the lifting mechanism 230. The ejection mechanism 24 is used to block materials and push them into the separating device.

[0042] Specifically, the fixed frame 210 includes two fixed vertical rods, which are spaced apart in a first direction parallel to the horizontal direction, and each fixed vertical rod extends vertically. Thus, the fixed frame 210 extends longitudinally in the vertical direction, thereby providing vertical support for the lifting mechanism 230. In this application, the first direction is the length direction of the fixed frame 210 (i.e., the direction of its length). Figure 1 The X direction is the first direction, and the second direction is the width direction of the fixed frame 210 (i.e., the X direction). Figure 1 The Y direction in the middle), the third direction is the height direction of the fixed frame 210 (i.e. Figure 1 (in the Z direction).

[0043] The lifting mechanism 230 includes a lifting panel 231, a drive assembly 232, two sets of lifting drive wheel sets 233, lifting chains 234, and lifting components 235. The lifting panel 231 is mounted between two fixed vertical rods and has a flat plate structure. The width of the lifting panel 231 extends along a first direction, the thickness along a second direction, and the length along a third direction. The two sets of lifting drive wheel sets 233 are respectively mounted at the bottom and top of the fixed frame 210. Two lifting chains 234 are respectively wound around the two sets of lifting drive wheel sets 233, with each lifting chain 234 spaced apart on opposite sides of the lifting panel 231 in the first direction. The drive assembly 232 is mounted on the top of the fixed frame 210 and is connected to the lifting drive wheel set 233 located at the top. Multiple lifting components 235 are arranged spaced apart along the length of the lifting chains 234, with each lifting component 235 fixed to two lifting chains 234 at both ends in the first direction.

[0044] Thus, the lifting mechanism 230 forms a transmission channel extending along the third direction, the driving component 232 drives the lifting drive wheel group 233 to rotate, thereby driving the lifting chain 234 to move upward in a cycle, and finally driving the lifting component 235 located on one side of the lifting panel 231 to move upward along the lifting panel 231, thereby conveying the material carried on it to move upward along the third direction.

[0045] The ejection mechanism 24 is mounted on the top of the fixed frame 210. The ejection mechanism 24 is constructed to form a curved and extended ejection surface, and the distance between the ejection surface and the lifting panel 231 gradually increases in the material conveying direction. Therefore, the material on the lifting assembly 235 is pushed away from the lifting panel 231 by the ejection surface until it falls from the lifting assembly 235 into the identification and differentiation device 400.

[0046] like Figures 1 to 4 As shown, the identification and differentiation device 400 is mounted on top of the fixed frame 210 and includes a main frame 410, a visual recognition mechanism 420, a waste bin 430, a material discharge mechanism 440, and a material blocking mechanism 450. The main frame 410 is configured to form an identification cavity 419 for receiving materials. The visual recognition mechanism 420 is located on one side of the identification cavity 419 and is used to acquire images of the materials within the identification cavity 419 and obtain material characteristics based on the images. The waste bin 430 is located on one side of the identification cavity 419, and a waste inlet is provided at the top of the waste bin 430 facing the visual recognition mechanism 420. The material discharge mechanism 440 includes a material discharge bin 441 located between the identification cavity 419 and the waste bin 430. The material discharge bin 441 has a material discharge inlet at the top of the visual recognition mechanism 420, and a material discharge outlet communicating with the material discharge inlet is provided at the bottom of the material discharge bin 441 away from the visual recognition mechanism 420. The material blocking mechanism 450 is located between the identification cavity 419 and the waste bin 430. The material blocking mechanism 450 controls the identification cavity 419 to selectively connect to either the waste bin 430 or the discharge bin 441.

[0047] Thus, under the action of the ejection mechanism 24, the material falling from the lifting component 235 enters the identification cavity 419. The visual recognition mechanism 420 can acquire an image of the material in the identification cavity 419 and obtain the material characteristics based on the image, thereby determining whether the material is an empty tube, an irregularly shaped yarn tube, or a normal yarn tube 600. The material blocking mechanism 450 causes the empty tube and irregularly shaped yarn tube to fall into the waste bin 430 according to the judgment result, while the normal yarn tube 600 falls into the discharge bin 441. Therefore, the above-mentioned identification and differentiation device 400 combines visual algorithms and mechanical mechanisms. Through the coordinated action of the visual recognition mechanism 420 and the material blocking mechanism 450, it efficiently and accurately realizes the function of removing empty tubes and irregularly shaped yarn tubes from the normal yarn tube 600, improving the working efficiency of the feeding equipment 100.

[0048] Specifically, the main frame 410 is generally cubic in shape, including a base plate 411, a left side plate 413, a right side plate 415, and a front plate 417. The base plate 411 is generally rectangular, extending lengthwise along a first direction, widthwise along a second direction, and thicknesswise along a third direction. The left side plate 413 and right side plate 415 are located at opposite ends of the base plate 411 in the first direction, and the front plate 417 is located on the side of the base plate 411 in the second direction and connects to the left side plate 413 and right side plate 415. When the main frame 410 is mounted on the fixed frame 210, the fixed frame 210 is fixed to the side of the base plate 411 away from the front plate 417 in the first direction, and the ejection mechanism 24 is located above the side of the main frame 410 away from the front plate 417.

[0049] The identification cavity 419 is formed within the main frame 410, and its length extends along the first direction. The identification cavity 419 is located obliquely below the ejection mechanism 24, so the material ejected by the ejection mechanism 24 can smoothly enter the identification cavity 419. It is understood that the shape of the identification cavity 419 is not limited and can be set as needed to meet the material containment requirements.

[0050] The visual recognition mechanism 420 includes a visual recognition bracket 421 and a visual recognition module 423. The visual recognition bracket 421 is mounted above the ejector mechanism 24 and extends vertically upwards along a third direction. The visual recognition module 423 is mounted on the top of the visual recognition bracket 421 away from the ejector mechanism 24 and facing the recognition cavity 419. The visual recognition module 423 includes a camera, thus enabling it to acquire images of the material in the recognition cavity 419 and obtain material characteristics based on the images. This allows it to determine whether the material is an empty tube, an irregularly shaped yarn tube, or a normal yarn tube 600, and further determine the positions of the large and small ends of a normal yarn tube 600. In this way, the shape of the yarn tube 600 can be quickly and accurately obtained using the visual recognition mechanism 420.

[0051] The material blocking mechanism 450 includes a first material blocking component 452, a second material blocking component 454, and a distinguishing component 456. The first material blocking component 452, the second material blocking component 454, and the distinguishing component 456 work together to guide the material in the identification cavity 419 into the waste bin 430 or the discharge bin 441.

[0052] The first baffle assembly 452 is located in the second direction between the identification cavity 419 and the discharge bin 441, and includes a first baffle drive 4521 and a first baffle plate 4523. The front plate 417 has a connecting groove that connects to the identification cavity 419. The first baffle drive 4521 is installed on the side of the front plate 417 facing the identification cavity 419. The first baffle plate 4523 is installed on the first baffle drive 4521. The first baffle drive 4521 can drive the first baffle plate 4523 to reciprocate along a third direction relative to the identification cavity 419 to be misaligned or aligned with the connecting groove, thereby connecting or blocking the identification cavity 419 and the discharge bin 441.

[0053] Specifically, when the first baffle drive 4521 drives the first baffle plate 4523 to move to its highest position along the third direction, the first baffle plate 4523 and the connecting groove are misaligned in the second direction. Therefore, the identification cavity 419 and the discharge bin 441 can communicate with each other, and the material can move from the identification cavity 419 to above the discharge bin 441. When the first baffle plate 4523 moves to its lowest position along the third direction under the drive of the first baffle drive 4521, the first baffle plate 4523 and the connecting groove are aligned in the second direction. Therefore, the identification cavity 419 and the discharge bin 441 are blocked by the first baffle plate 4523, and the material cannot leave the identification cavity 419 due to the obstruction of the first baffle plate 4523.

[0054] The second baffle assembly 454 is located between the discharge bin 441 and the waste bin 430, and includes a second baffle drive 4541 and a second baffle plate 4543. The second baffle drive 4541 is mounted on the side of the front plate 417 opposite to the identification cavity 419, and the second baffle plate 4543 is mounted on the second baffle drive 4541. The second baffle drive 4541 can drive the second baffle plate 4543 to move relative to the identification cavity 419 in a third direction to be misaligned or aligned with the connecting groove, thereby connecting or blocking the discharge bin 441 and the waste bin 430. A discharge gap is formed between the first baffle plate 4523 and the second baffle plate 4543, which can selectively connect the identification cavity 419 and the discharge bin 441.

[0055] Specifically, when the second baffle drive 4541 drives the second baffle plate 4543 to move to the highest position along the third direction, the second baffle plate 4543 and the connecting groove are misaligned in the second direction. Therefore, the identification cavity 419 and the discharge bin 441 can communicate with each other, and the material can move from the identification cavity 419 to above the discharge bin 441. When the second baffle plate 4543 moves to the lowest position along the third direction under the drive of the second baffle drive 4541, the second baffle plate 4543 and the connecting groove are aligned in the second direction. Therefore, the discharge bin 441 and the waste bin 430 are blocked by the first baffle plate 4523, and the material cannot leave the discharge gap formed between the first baffle plate 4523 and the second baffle plate 4543 due to the obstruction of the second baffle plate 4543.

[0056] The separating component 456 is located above the discharge bin 441 and below the identification cavity 419. The separating component 456 is movable relative to the discharge bin 441 to extend into or out of the discharge gap. Specifically, the separating component 456 includes a first separating member 4561, a second separating member 4563, a first separating drive member 4565, and a second separating drive member 4567. The first separating drive member 4565 and the second separating drive member 4567 are spaced apart along a first direction. The first separating member 4561 and the second separating member 4563 are respectively tractively connected to one end of the first separating drive member 4565 and the second separating drive member 4567 in a second direction. One of the first separating member 4561 and the second separating member 4563 is controlled to extend into or out of the discharge gap along the second direction.

[0057] When both the first partition 4561 and the second partition 4563 are located in the material discharge gap, they are both above the material inlet of the discharge bin 441. The material can remain in the material discharge gap and roll into the waste bin 430, supported by the first partition 4561 and the second partition 4563. When either the first partition 4561 or the second partition 4563 leaves the material discharge gap, one end of the material loses support and preferentially falls into the discharge bin 441, thus achieving material posture adjustment.

[0058] In some embodiments, a connecting plate 4172 is further provided on the side of the front plate 417 facing the waste bin 430. One end of the connecting plate 4172 is connected to the front plate 417 and located on one side of the separating component 456 in the second direction, and the other end of the connecting plate 4172 extends toward the waste bin 430. In this way, the material in the identification cavity 419 rolls down along the separating component 456 and the connecting plate 4172 into the waste bin 430.

[0059] In some embodiments, the identification and differentiation device 400 further includes a feed detection component 460, which is disposed on at least one side of the identification cavity 419 and is used to detect whether there is material in the identification cavity 419. When the feed detection component 460 detects that there is material in the identification cavity 419, it activates the visual recognition module 423 to acquire an image of the material.

[0060] In one specific embodiment, the feed detection component 460 includes a pair of photoelectric through-beam sensors. The transmitting end and receiving end of the photoelectric through-beam sensors are located on opposite sides of the recognition cavity 419 in the first direction. The transmitting end can emit a light beam to the receiving end. When there is no material in the recognition cavity 419, the light beam can reach the receiving end normally and the receiving end can receive the light beam. When there is material in the recognition cavity 419, the light beam cannot reach the receiving end normally, so the receiving end cannot receive the light beam. Therefore, it is determined that there is material in the recognition cavity 419.

[0061] In some embodiments, the identification and differentiation device 400 further includes a clamping mechanism 470. The clamping mechanism 470 includes two sets of clamping components located on opposite sides of the identification cavity 419 in a first direction. The two sets of clamping components are controlled to move closer or further apart along the first direction to form a clamping gap for holding material within the identification cavity 419. Thus, when material enters the identification cavity 419, the clamping mechanism 470 can clamp the material to stabilize its posture and then immediately retract, at which point the visual recognition mechanism 420 can capture an image of the material.

[0062] Specifically, each clamping assembly includes a clamping drive 472 mounted on the main frame 410 and a clamping plate 474 connected to one end of the clamping drive. The clamping drive 472 can drive the clamping plate 474 to reciprocate in a first direction to clamp or release the material.

[0063] In some embodiments, the width of the discharge bin 441 gradually decreases from top to bottom in a first direction. The discharge bin 441 includes a first discharge housing 4412, a second discharge housing 4414, a first discharge drive member 4416, and a second discharge drive member 4418. The first discharge housing 4412 and the second discharge housing 4414 are arranged opposite each other in the horizontal direction. The first discharge drive member 4416 is fixed to the main frame 410 and driveably connected to the first discharge housing 4412, and the second discharge drive member 4418 is fixed to the main frame 410 and driveably connected to the second discharge housing 4414. Driven by the first discharge drive member 4416 and the second discharge drive member 4418, the first discharge housing 4412 and the second discharge housing 4414 can move relative to each other in the first direction to close or separate.

[0064] Thus, when the identification and differentiation device 400 is in normal working condition, the first discharge housing 4412 and the second discharge housing 4414 close to adjust the falling posture of the material. When individual materials have difficulty falling due to size issues, the first discharge housing 4412 and the second discharge housing 4414 can be separated under the drive of the first discharge drive 4416 and the second discharge drive 4418, thereby facilitating maintenance personnel to handle the materials accumulated in the discharge bin 441.

[0065] Furthermore, the material feeding mechanism 440 also includes a guide rail mounting base 443, a material feeding guide rail 445, a first material feeding slider 447, and a second material feeding slider 449. The guide rail mounting base 443 is fixed to the base plate 411 of the main frame 410. The material feeding guide rail 445 is mounted on the guide rail mounting base 443 and extends along a first direction. The first material feeding slider 447 is movably mounted on the material feeding guide rail 445 and fixed to the first material feeding housing 4412. The second material feeding slider 449 is movably mounted on the material feeding guide rail 445 and fixed to the second material feeding housing 4414. Thus, driven by the first material feeding drive member 4416, the first material feeding housing 4412 reciprocates along the material feeding guide rail 445 in the first direction. Driven by the second material feeding drive member 4418, the second material feeding housing 4414 reciprocates along the material feeding guide rail 445 in the second direction.

[0066] In this application, the first stop drive 4521, the second stop drive 4541, the first separation drive 4565, the second separation drive 4567, the first dropping drive 4416, the second dropping drive 4418, and the clamping drive 472 are all formed by cylinders. It is understood that in some other embodiments, the above-mentioned drive structures may also be formed by drive elements such as motors.

[0067] The working principle of the above-mentioned identification and differentiation device 400 for identifying and differentiating yarn tubes 600 is as follows:

[0068] The feeding detection device detects whether the yarn tube 600 is present in the identification cavity 419. At this time, both the first baffle plate 4523 and the second baffle plate 4543 are in their lowest positions. The yarn tube 600 that falls into the identification cavity 419 is held in place by the first baffle plate 4523. At the same time, the first dividing part 4561 and the second dividing part 4563 extend into the dropping gap, and the first dropping housing 4412 and the second dropping housing 4414 close together.

[0069] When the detection and recognition cavity 419 contains yarn tube 600, the clamping mechanism 470 clamps the yarn tube 600 to stabilize its position and then retracts. The vision recognition mechanism 420 acquires an image of the yarn tube 600 in the recognition cavity 419 and obtains material characteristics based on the image. When the vision recognition mechanism 420 determines that the yarn tube 600 in the recognition cavity 419 is an empty tube or an irregularly shaped yarn tube 600, the first baffle plate 4523 rises to its highest position under the drive of the first baffle plate 4523 drive member, and at the same time, the second baffle plate 4543 rises to its highest position under the drive of the second baffle plate 4543 drive member. At this time, the distinguishing component 456 is still located within the dropping gap to prevent the yarn tube 600 from falling into the dropping bin 441. Therefore, the empty tube or irregularly shaped yarn tube 600 falls from the recognition cavity 419 through the distinguishing component 456 into the waste bin 430.

[0070] When the visual recognition mechanism 420 determines that the yarn tube 600 in the recognition cavity 419 is a normal yarn tube 600, it acquires the position information of the large end and the small end of the yarn tube 600. The first baffle plate 4523 rises to its highest position under the drive of the first baffle drive member 4521, while the position of the second baffle plate 4543 remains unchanged. Therefore, the yarn tube 600 stops above the separating component 456 under the obstruction of the second baffle plate 4543. According to the position of the large end and the small end of the yarn tube 600, the first separating component 4561 or the second separating component 4563 corresponding to the large end of the yarn tube 600 is controlled to retract and leave the dropping gap. Therefore, the large end of the yarn tube 600 falls into the dropping bin 441 first, forming a large end downward posture.

[0071] The aforementioned identification and differentiation device 400 and feeding equipment 100, by combining visual algorithms with mechanical structures, can quickly and accurately determine the size of the ends of the yarn tube 600 and the forming quality of the yarn tube 600. They also possess the functions of differentiating between large and small ends and rejecting irregularly shaped yarn tubes 600, thereby improving the overall working efficiency of the feeding equipment 100. Furthermore, the identification and differentiation device 400 has a compact overall structure, reducing the number of driving components compared to existing technologies and decreasing the air consumption during equipment operation.

[0072] 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.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
