Description

Technical Field

[0001] This application relates to the field of automatic detection technology, specifically to a tire detection and sorting device. Background Technology

[0002] Tires require multiple inspections after production to ensure quality. Existing inspection methods require multiple workers to perform different inspections on each tire, and these inspections are conducted using manual fixtures, leading to the following problems:

[0003] 1. The inconsistent operating speeds of multiple staff members affect the overall efficiency of tire inspection;

[0004] 2. Using manual fixtures for inspection can lead to errors due to misoperation, affecting the inspection results and causing potential quality issues with the tires. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a tire inspection and sorting device, which can improve inspection efficiency and reduce the number of operators while ensuring inspection accuracy.

[0006] The tire inspection and material distribution device according to an embodiment of the present invention includes a feeding position, a loading position, an inspection position, a material distribution position, and a discharge position, comprising:

[0007] A feeding mechanism that conveys tires from the discharge position to the loading position;

[0008] A material transfer mechanism that transfers the tire located at the loading position to the detection position;

[0009] A detection mechanism that detects the tire at the detection position;

[0010] The tires that have completed the inspection are transported from the inspection station to the unloading channel of the material sorting station;

[0011] The material distribution and discharge mechanism at the material distribution position transports the tire located at the material distribution position to the material discharge position.

[0012] The material distribution and discharge mechanism is equipped with a good product discharge port and a defective product discharge port at the discharge position. The material distribution and discharge mechanism delivers the tire to the good product discharge port or the defective product discharge port according to the detection results of the detection mechanism.

[0013] According to the tire inspection and sorting device of the present invention, the inspection and sorting of tires can be completed automatically, reducing the number of operators required for tire inspection and sorting and improving the efficiency of tire inspection. At the same time, it can reduce inspection errors caused by human error, improve the accuracy of tire inspection and sorting, and reduce potential quality problems in sorted good tires.

[0014] In some embodiments, the feeding mechanism includes: a feeding channel, the height of which gradually decreases from the unloading position to the feeding position; and a feeding and separating mechanism that separates individual tires and positions them at the feeding position. Thus, the tires can roll from the unloading position to the feeding position within the feeding channel under the influence of gravity. Furthermore, it facilitates the transfer mechanism in moving the tires at the feeding position, avoiding or reducing obstruction from other tires when the transfer mechanism moves a tire from the feeding position.

[0015] Furthermore, the feeding and distributing mechanism includes: a positioning mechanism, which is located on one side of the feeding channel and is movable toward the feeding position; and a blocking mechanism, which is located on one side of the feeding channel, is movable toward the feeding channel, and is also movable along the extending direction of the feeding channel. When a tire moves to the feeding position, the positioning mechanism moves toward the feeding position to press the tire against the feeding position, and the blocking mechanism simultaneously moves toward the feeding channel and along the extending direction of the feeding channel to separate the tire within the feeding position from the tires outside the feeding position. Therefore, the feeding and distributing mechanism is applicable to tires of different sizes, improving the versatility of the feeding and distributing mechanism and the tire detection and distributing device.

[0016] Specifically, the positioning mechanism includes a positioning drive and a positioning plate. The positioning drive controls the positioning plate to move towards the loading position. The blocking mechanism includes a blocking component, a blocking drive, and a blocking guide rail extending along the loading channel. The blocking drive is slidably mounted on the blocking guide rail and controls the blocking component to move towards the loading channel. When a tire moves to the loading position, the positioning drive controls the positioning plate to move towards the loading position, and the positioning plate presses the tire against the loading position. The blocking drive moves along the blocking guide rail and controls the blocking component to move into the loading channel, separating the tire inside the loading position from the tire outside the loading position. Thus, the positioning drive and the blocking drive can drive the positioning plate and the blocking component to move respectively, thereby enabling the loading and separating mechanism to automatically separate individual tires and position them at the loading position.

[0017] In some embodiments, the material transfer mechanism includes: a clamping member; a clamping drive member, the clamping drive member controlling the clamping member to clamp or release the tire; a first material transfer guide rail, the clamping member being movably disposed on the first material transfer guide rail along a first direction; and a second material transfer guide rail, the first material transfer guide rail being movably disposed on the second material transfer guide rail along a second direction. The clamping member clamps the tire at the loading position and releases the tire at the detection position. Thus, the clamping member can move in both the first and second directions, so that after clamping the tire at the loading position, the clamping member can drive the tire to move in both the first and second directions to the detection position, and release the tire at the detection position, thereby automatically transferring the tire from the loading position to the detection position.

[0018] In some embodiments, the tire includes an outer tire and an inner tire, and the detection mechanism includes: a concentricity detection mechanism; a yaw rate detection mechanism; and a tire drive mechanism, the tire drive mechanism controlling the tire to rotate about the central axis of the inner tire; wherein, when the tire is in the detection position, the concentricity detection mechanism abuts against the radially outer side of the outer tire, and the yaw rate detection mechanism abuts against the axially outer side of the inner tire. Thus, automatic detection of the concentricity and yaw rate between the inner tire and the outer tire can be achieved.

[0019] Furthermore, the tire drive mechanism includes: a positioning drive shaft extending axially along the inner tube; a positioning driven shaft whose axis coincides with the axis of the positioning drive shaft; and a power output component connected to the end of the positioning drive shaft away from the positioning driven shaft. When the tire is in the detection position, the axes of the inner tube, the positioning drive shaft, and the positioning driven shaft coincide, and the tire is sandwiched between the positioning drive shaft and the positioning driven shaft. Thus, the tire drive mechanism can define the rotation axis of the inner tube as its central axis through the positioning drive shaft and the positioning driven shaft, and cause the power output component to drive the inner tube to rotate through the positioning drive shaft, thereby achieving stable rotation control of the tire.

[0020] Furthermore, at least one of the positioning drive shaft and the positioning driven shaft can move axially along the inner tube. Thus, when the axial distance between the positioning drive shaft and the positioning driven shaft decreases, the tire can be axially clamped between the two shafts to control tire rotation for detection; when the axial distance between the two shafts increases, the tire can detach from between them, allowing it to leave the detection position for subsequent tire sorting and unloading.

[0021] Furthermore, the end of the positioning driven shaft furthest from the positioning driven shaft is connected to a rotation detection element. Thus, the rotation detection element can detect the tire's rotation data, thereby monitoring the tire's rotation to ensure stable tire rotation and improving the accuracy of tire detection.

[0022] Furthermore, the concentricity detection mechanism includes a first contact member and a first vibration sensor, the first contact member and the first vibration sensor being rigidly connected; the yaw detection mechanism includes a second contact member and a second vibration sensor, the second contact member and the second vibration sensor being rigidly connected; wherein, when the tire is located at the detection position, the first contact member abuts against the radial outer side of the outer tire, and the second contact member abuts against the axial outer side of the inner tire. Thus, concentricity and yaw information are converted into vibration information, which is then processed by the first and second vibration sensors respectively, thereby enabling the detection of tire concentricity and yaw.

[0023] In some embodiments, the detection mechanism is movable along the extension direction of the feeding channel, so that the position of the detection device can be moved to meet the detection requirements of tires of different sizes, thereby making the detection device applicable to tires of different sizes and improving the versatility of the detection device and the tire detection and sorting device.

[0024] In some embodiments, the material sorting and discharging mechanism includes: a good product discharge channel connected to the good product outlet, the good product discharge channel gradually decreasing in height towards the good product outlet; a defective product discharge channel connected to the defective product outlet, the defective product discharge channel gradually decreasing in height towards the defective product outlet; and a sorting channel movably disposed between the feeding channel, the good product discharge channel, and the defective product discharge channel; wherein, when the tire moves from the detection position to the sorting position, the sorting channel connects and communicates with the feeding channel. Thus, the sorting channel can receive tires that have completed detection and left the detection position, and transfer the tires to the good product discharge channel and the defective product discharge channel according to the detection results, automatically sorting the tires according to the detection results.

[0025] Furthermore, the material distribution channel is configured with parallel good product distribution channel and defective product distribution channel, and the material distribution channel has a first position and a second position, and the material distribution channel can be translated between the first position and the second position; when the material distribution channel is in the first position, the good product distribution channel is connected to the unloading channel, and the defective product distribution channel is connected to the defective product discharge channel; when the material distribution channel is in the second position, the defective product distribution channel is connected to the unloading channel, and the good product distribution channel is connected to the good product discharge channel. Thus, the material distribution channel can control the good product distribution channel to connect to the good product discharge channel or the defective product distribution channel to connect to the defective product discharge channel according to the tire inspection results, realizing the material distribution and discharge of tires. At the same time, the maximum travel distance of the material distribution channel is smaller, thereby reducing the failure caused by the long travel distance of the material distribution channel.

[0026] Furthermore, the material distribution channel is equipped with a material distribution sensor. When the material distribution sensor detects that the tire has moved into the material distribution channel, the material distribution channel moves and connects with the good product discharge channel or the defective product discharge channel. Thus, the material distribution sensor can detect whether there is a tire in the material distribution channel, and the material distribution channel can move accordingly based on whether there is a tire in the material distribution channel.

[0027] Furthermore, both the good product discharge channel and the defective product discharge channel are equipped with discharge sensors at one end near the sorting position. When the discharge sensor detects that the tire has entered the good product discharge channel or the defective product discharge channel, the sorting channel moves and connects with the discharge channel. Thus, the discharge sensor can detect whether a tire has entered the good product discharge channel or the defective product discharge channel. When the discharge sensor detects that a tire has entered the good product discharge channel or the defective product discharge channel, it means that the tire has left the sorting channel. Therefore, the sorting channel can move according to whether a tire has entered the good product discharge channel or the defective product discharge channel.

[0028] In some specific embodiments, the detection device further includes a material arrival sensor, which detects the tire entering the detection position, and the detection device then detects the tire. Thus, the detection device can perform detection operations based on whether a tire is present at the detection position, enabling the tire detection to begin automatically.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0070] The tire detection and sorting device 100 according to an embodiment of this application is described below with reference to the accompanying drawings.

[0071] like Figure 1 As shown, the tire inspection and material distribution device 100 according to the embodiment of this application is provided with a feeding position 10a, a feeding position 10b, an inspection position 10c, a material distribution position 10d and a discharge position 10e, including: a feeding mechanism 11, a material transfer mechanism 12, an inspection mechanism 13, a material unloading channel 14 and a material distribution and discharge mechanism 15.

[0072] The feeding mechanism 11 conveys tires from the unloading position 10a to the loading position 10b. The transferring mechanism 12 moves the tires located at the loading position 10b to the detection position 10c. The detection mechanism 13 detects the tires at the detection position 10c. The unloading channel 14 conveys the tires that have completed the detection from the detection position 10c to the sorting position 10d. The sorting and discharging mechanism 15 conveys the tires located at the sorting position 10d to the discharge position 10e.

[0073] The material distribution and discharge mechanism 15 is equipped with a good product discharge port 15a and a defective product discharge port 15b at the discharge position 10e. The material distribution and discharge mechanism 15 delivers the tires to the good product discharge port 15a or the defective product discharge port 15b according to the detection results of the detection mechanism 13.

[0074] In the tire inspection and sorting device 100 of this application, after a tire is placed at the feeding position 10a, the feeding mechanism 11 transports the tire to the feeding position 10b, and the transferring mechanism 12 can transfer the tire from the feeding position 10b to the inspection position 10c so that the inspection mechanism 13 can inspect the tire. After the inspection is completed, the tire can move to the sorting position 10d through the unloading channel 14, and the sorting and discharging mechanism 15 transports the tire to the good product outlet 15a or the defective product outlet 15b according to the inspection result of the inspection mechanism 13 to complete the discharge. Thus, when the operator places the tire at the feeding position 10a, the tire inspection and sorting device 100 can realize automatic tire inspection and automatic tire sorting and discharge according to the inspection result.

[0075] The tire inspection and sorting device 100 of this application can automatically complete the inspection and sorting of tires, reducing the number of operators required for tire inspection and sorting, and improving the efficiency of tire inspection. At the same time, it can reduce the inspection error caused by human operation, improve the accuracy of tire inspection and sorting, and reduce the quality risks of sorted good tires.

[0076] It is understandable that the tire inspection and sorting device 100 of this application can be adapted to tires of different sizes and has high versatility.

[0077] In the embodiments of this application, the structure of the detection mechanism 13 can be set according to the detection parameters of the tire, and is not limited here. For example, in Figure 1 In the example, the detection device is set to detect the concentricity and yaw of the tire. The detection device is equipped with a concentricity detection mechanism 131 and a yaw detection mechanism 132.

[0078] The tire inspection and material distribution device 100 of this application includes a feeding mechanism 11, a transferring mechanism 12, an inspection mechanism 13, a discharging channel 14, and a material distribution and discharge mechanism 15, which can be simultaneously arranged on one workbench or separately on multiple workbenches. Figure 1In the example, the feeding mechanism 11, the transferring mechanism 12, the detection mechanism 13, the unloading channel 14, and the distributing and discharging mechanism 15 are set on a workbench, and the feeding position 10a, the feeding position 10b, the detection position 10c, the distributing position 10d, and the discharging position 10e are distributed at various locations on the workbench.

[0079] In some embodiments, such as Figure 2 , Figure 3 As shown, the feeding mechanism 11 includes a feeding channel 111 and a feeding distribution mechanism 112. The height of the feeding channel 111 gradually decreases from the unloading position 10a to the feeding position 10b, and the feeding distribution mechanism 112 separates individual tires and positions them at the feeding position 10b.

[0080] It is understandable that when a tire is placed vertically, that is, when the tire's axis is horizontal, the tire can roll in a direction perpendicular to the axis.

[0081] Therefore, after the tire is placed at the discharge position 10a, it can roll from the discharge position 10a to the loading position 10b within the loading channel 111 under the action of gravity, that is, the tire can automatically move from the discharge position 10a to the loading position 10b. The loading and separating mechanism 112 separates individual tires and positions them at the loading position 10b, which facilitates the transfer mechanism 12 to move the tires at the loading position 10b and avoids or reduces the obstruction of other tires when the transfer mechanism 12 moves the tires out of the loading position 10b.

[0082] It should be noted that, in order to ensure that the tire axis is horizontal, the width of the feeding channel 111 is set to be slightly larger than the width of the tire.

[0083] Preferably, the feeding mechanism 11 is equipped with a feeding sensor 113, which is used to detect whether there is a tire in the feeding position 10b. When the feeding mechanism 11 detects that there is a tire in the feeding position 10b, the feeding and separating mechanism 112 separates the tire in the feeding position 10b from the tire outside the feeding position 10b, and at the same time, the material transfer mechanism 12 transfers the tire in the feeding position 10b.

[0084] Furthermore, the feeding and distributing mechanism 112 includes a positioning mechanism 1121 and a blocking mechanism 1122. The positioning mechanism 1121 is located on one side of the feeding channel 111 and is movable toward the feeding position 10b. The blocking mechanism 1122 is located on one side of the feeding channel 111 and is movable toward the feeding channel 111, and is movable along the extending direction of the feeding channel 111.

[0085] When a tire moves to the loading position 10b, the positioning mechanism 1121 moves toward the loading position 10b to press the tire against the loading position 10b, thus positioning the tire at the loading position 10b. The tire's position at the loading position 10b is fixed, improving the stability when the transfer mechanism 12 moves the tire out of the loading position 10b. The blocking mechanism 1122 moves simultaneously toward the loading channel 111 and along the extension direction of the loading channel 111 to separate the tires inside the loading position 10b from the tires outside the loading position 10b. That is, the blocking mechanism 1122 pushes the tires that have not yet entered the loading position 10b toward the unloading position 10a a short distance.

[0086] It is understandable that for tires of different sizes, due to the difference in tire diameter, when the loading position 10b accommodates tires of different diameters, the contact position between the tires inside the loading position 10b and the tires outside the loading position 10b will also be different.

[0087] Therefore, the retaining mechanism 1122 can move along the extending direction of the feeding channel 111. Corresponding to tires of different sizes, the retaining mechanism 1122 can move along the feeding channel 111 according to the tire size, and move towards the feeding channel 111 to insert the tire into the feeding position 10b and the tire outside the feeding position 10b. Thus, the feeding and distributing mechanism 112 can be applied to tires of different sizes, improving the versatility of the feeding and distributing mechanism 112 and the tire detection and distributing device 100.

[0088] Specifically, the positioning mechanism 1121 is equipped with a positioning drive (not shown in the figure) and a positioning plate. The positioning drive controls the positioning plate to move toward the loading position 10b.

[0089] The material blocking mechanism 1122 is provided with a material blocking component 1122a, a material blocking drive component 1122b (not shown in the figure) and a material blocking guide rail 1122c extending along the feeding channel 111. The material blocking drive component 1122b is slidably disposed on the material blocking guide rail 1122c and controls the material blocking component 1122a to move toward the feeding channel 111.

[0090] When a tire moves to the loading position 10b, the positioning drive controls the positioning plate to move toward the loading position 10b, and the positioning plate presses the tire against the loading position 10b. The blocking drive 1122b moves on the blocking guide rail 1122c and controls the blocking part 1122a to move into the loading channel 111 to separate the tires in the loading position 10b from the tires outside the loading position 10b.

[0091] Understandably, when the tire at the loading position 10b is removed by the material transfer mechanism 12, the positioning drive controls the positioning plate to move away from the loading position 10b, and the blocking drive 1122b controls the blocking part 1122a to move out of the loading channel 111, so as to avoid the positioning plate and the blocking part 1122a from blocking the next tire from entering the loading position 10b.

[0092] Thus, the positioning drive and the baffle drive 1122b can drive the movement of the positioning plate and the baffle 1122a respectively, thereby enabling the feeding and distributing mechanism 112 to automatically separate individual tires and position the tires at the feeding position 10b.

[0093] In this application, the mechanism of the positioning plate and the stop 1122a is not limited. For example, in Figure 2 , Figure 3 In the example, the stop 1122a is set as a stop bar.

[0094] In this application, the structure of the positioning drive and the stop drive 1122b is not limited. The positioning drive and the stop drive 1122b can be, for example, a motor or a cylinder.

[0095] In some embodiments, such as Figure 3 , Figure 4 As shown, the material transfer mechanism 12 includes: a clamping member 121, a clamping drive member (not shown in the figure), a first material transfer guide rail 122, and a second material transfer guide rail 123. The clamping drive member controls the clamping member 121 to clamp or release the tire. The clamping member is movably disposed on the first material transfer guide rail 122 along a first direction, and the first material transfer guide rail 122 is movably disposed on the second material transfer guide rail 123 along a second direction.

[0096] The clamping member 121 clamps the tire at the loading position 10b and releases the tire at the detection position 10c.

[0097] Thus, the clamping member 121 can move in the first direction and the second direction, so that after the clamping member 121 clamps the tire at the loading position 10b, the clamping member 121 can drive the tire to move to the detection position 10c in the first direction and the second direction, and release the tire at the detection position 10c, so as to realize the automatic transfer of the tire from the loading position 10b to the detection position 10c.

[0098] It should be noted that, of the two directions, the first direction is the direction in which the tire leaves the loading position and enters the detection position 10c, and the second direction is the direction extending from the loading position 10b toward the detection position 10c.

[0099] exist Figure 3 , Figure 4In the example, the first direction is vertical, and the tire leaves the loading position 10b vertically. The second direction is horizontal, and the clamping member 121 moves along the second direction from above the loading position 10b to above the detection position 10c vertically.

[0100] In some embodiments, such as Figures 6-8 As shown, the tire includes an outer tire and an inner tire. The detection mechanism 13 includes a concentricity detection mechanism 131, a runout detection mechanism 132, and a tire drive mechanism 133. The tire drive mechanism 133 controls the tire to rotate around the central axis of the inner tire.

[0101] When the tire is in the detection position 10c, the concentricity detection mechanism 131 abuts against the radial outer side of the outer tire, and the sway detection mechanism 132 abuts against the axial outer side of the inner tire.

[0102] Understandably, during the rotation of the tire around the inner tube axis, the tire's concentricity can be reflected in the radial dimensional consistency of the tire. That is, when the tire rotates, if the tire is an ideal circle, the concentricity detection mechanism 131 will not detect vibration at the contact point; if the tire is not an ideal circle, the concentricity detection mechanism 131 will detect vibration of a certain amplitude at the contact point. In this case, the concentricity detection mechanism 131 will evaluate the tire's concentricity based on the detected vibration amplitude.

[0103] Correspondingly, the tire's runout can be reflected in the dimensional consistency of points on the outer circumference of the inner tube. That is, when the tire has no runout in the axial direction, the runout detection mechanism 132 will not detect vibration at the contact point; when the tire has a certain runout in the axial direction, the runout detection mechanism 132 will detect vibration of a certain amplitude at the contact point, and at this time, the runout detection mechanism 132 will evaluate the tire's runout based on the detected vibration amplitude.

[0104] This enables automatic detection of tire concentricity and runout.

[0105] Furthermore, the tire drive mechanism 133 includes: a positioning drive shaft 1331, a positioning driven shaft 1332, and a power output component 1333. The positioning drive shaft 1331 extends axially along the inner tube, the axis of the positioning driven shaft 1332 coincides with the axis of the positioning drive shaft 1331, and the power output component 1333 is drively connected to the end of the positioning drive shaft 1331 away from the positioning driven shaft 1332.

[0106] When the tire is in the detection position 10c, the axes of the inner tube, the positioning drive shaft 1331 and the positioning driven shaft 1332 coincide, and the tire is clamped between the positioning drive shaft 1331 and the positioning driven shaft 1332.

[0107] Thus, the tire drive mechanism 133 can define the inner tube's rotation axis as its central axis by positioning the drive shaft 1331 and the driven shaft 1332, and make the power output component 1333 drive the inner tube to rotate through the drive shaft 1331, thereby achieving stable control of the tire's rotation.

[0108] The type of power output component 1333 is not limited in this application. For example, the power output component 1333 may be an electric motor.

[0109] Furthermore, at least one of the positioning drive shaft 1331 and the positioning driven shaft 1332 is axially movable along the inner tube. It is understood that in order to ensure that the tire can rotate stably with the positioning drive shaft 1331, the tire needs to be clamped between the positioning drive shaft 1331 and the positioning driven shaft 1332.

[0110] Therefore, by moving at least one of the positioning drive shaft 1331 and the positioning driven shaft 1332 along the inner tube axial direction, the axial distance between the positioning drive shaft 1331 and the positioning driven shaft 1332 can be adjusted. When the axial distance between the positioning drive shaft 1331 and the positioning driven shaft 1332 decreases, the tire can be axially clamped between the positioning drive shaft 1331 and the positioning driven shaft 1332 to control the rotation of the tire for detection; when the axial distance between the positioning drive shaft 1331 and the positioning driven shaft 1332 increases, the tire can detach from the positioning drive shaft 1331 and the positioning driven shaft 1332, allowing the tire to leave the detection position 10c for subsequent tire sorting and unloading.

[0111] Preferably, the inner tube has a positioning hole at its center, and the positioning drive shaft 1331 and the positioning driven shaft 1332 have a guide structure at the end where the tire is clamped. The cross-sectional size of the guide structure gradually decreases along the axis toward the inner tube, so that when the positioning drive shaft 1331 and the positioning driven shaft 1332 approach the inner tube along the axis, the positioning drive shaft 1331 and the positioning driven shaft 1332 can more easily enter the positioning hole through the guide structure, ensuring that the axes of the inner tube, the positioning drive shaft 1331 and the positioning driven shaft 1332 coincide.

[0112] Furthermore, the end of the positioning driven shaft 1332 furthest from the positioning driven shaft 1332 is connected to the rotation detection element 1334. Thus, the rotation detection element 1334 can detect the rotation data of the tire, thereby monitoring the tire's rotation to ensure stable tire rotation and improve the accuracy of tire detection.

[0113] In this application, the type of rotation detection device is not limited. For example, the rotation detection device is configured as an encoder coaxial with the positioning driven shaft 1332, and the encoder rotates synchronously with the positioning driven shaft 1332. This allows for the detection of rotational speed or the number of rotations.

[0114] Furthermore, such as Figure 9 , Figure 10 As shown, the concentricity detection mechanism 131 includes: a first contact 1311 and a first vibration sensor, wherein the first contact 1311 and the first vibration sensor are rigidly connected;

[0115] like Figure 11 , Figure 12 As shown, the yaw detection mechanism 132 includes: a second contact 1321 and a second vibration sensor, and the second contact 1321 and the second vibration sensor are rigidly connected.

[0116] When the tire is in detection position 10c, the first contact 1311 abuts against the radial outer side of the outer tire, and the second contact 1321 abuts against the axial outer side of the inner tire.

[0117] Understandably, hard connections enable better vibration transmission between two structures, with minimal vibration loss during transmission.

[0118] Therefore, the first contact 1311 and the second contact 1321 can receive vibrations on the radial outer side of the outer tire and the axial outer side of the inner tire, respectively. The vibrations detected by the first contact 1311 and the second contact 1321 can be transmitted to the first vibration sensor and the second vibration sensor, respectively, so as to convert the concentricity and yaw information into vibration information, and the vibration information is processed by the first vibration sensor and the second vibration sensor, respectively, to realize the detection of tire concentricity and yaw.

[0119] In addition, the first contact 1311 and the second contact 1321 can also be configured with a mechanism for amplifying vibration, thereby improving the detection accuracy of the concentricity detection mechanism 131 and the yaw detection mechanism 132.

[0120] In some embodiments, the detection mechanism 13 is movable along the extension direction of the feeding channel 14.

[0121] It is understandable that when tires of different sizes are located at detection position 10c, the positions of the tire's axle and radial side will differ.

[0122] Therefore, by moving the detection device, the position of the detection device can be moved to meet the detection requirements of tires of different sizes, thereby making the detection device applicable to tires of different sizes and improving the versatility of the detection device and the tire detection and sorting device 100.

[0123] In some embodiments, such as Figures 13-15 As shown, the material distribution and discharge mechanism 15 includes: a good product discharge channel 151, a defective product discharge channel 152, and a material distribution channel 153.

[0124] Good product discharge channel 151 connects to good product discharge port 15a, and the height of good product discharge channel 151 gradually decreases in the direction toward good product discharge port 15a. Defective product discharge channel 152 connects to defective product discharge port 15b, and the height of defective product discharge channel 152 gradually decreases in the direction toward defective product discharge port 15b. It is movably disposed between the feeding channel 14, the good product discharge channel 151, and the defective product discharge channel 152.

[0125] Specifically, when the tire moves from the detection position 10c to the sorting position 10d, the sorting channel 153 connects with the unloading channel 14; when the tire moves from the sorting position 10d to the good product outlet 15a, the sorting channel 153 connects with the good product outlet channel 151; and when the tire moves from the sorting position 10d to the defective product outlet 15b, the sorting channel 153 connects with the defective product outlet channel 152. It can be understood that because the height of the good product outlet channel 151 gradually decreases in the direction towards the good product outlet 15a, when the tire is placed vertically within the good product outlet channel 151 (i.e., the tire's axis is horizontal), the tire can roll in a direction perpendicular to its axis. The same applies to the defective product outlet channel 152.

[0126] Therefore, the material distribution channel 14 can receive tires that have completed the inspection and left the inspection position 10c, and transfer the tires to the good product discharge channel 151 and the defective product discharge channel 152 according to the inspection results, and automatically distribute the tires according to the inspection results.

[0127] Simultaneously, when the material distribution channel 153 is connected to the good product discharge channel 151, the tire can roll from the material distribution position 10d to the good product discharge port 15a within the good product discharge channel 151 under the action of gravity; when the material distribution channel 153 is connected to the defective product discharge channel 152, the tire can roll from the material distribution position 10d to the defective product discharge port 15b within the defective product discharge channel 152 under the action of gravity. This achieves automatic discharge of the tire from the material distribution and discharge mechanism 15.

[0128] This application does not impose any limitations on the structure of the material distribution channel 153. For example, in Figures 13-15In the example, the material distribution channel 153 is configured to have parallel good product distribution channel 1531 and defective product distribution channel 1532, and the material distribution channel 153 can be translated in the lateral direction and has a first position and a second position. When the material distribution channel 153 is in the first position, the good product distribution channel 1531 is connected to the unloading channel 14, and the defective product distribution channel 1532 is connected to the defective product discharge channel 152; when the material distribution channel 153 is in the second position, the defective product distribution channel 1532 is connected to the unloading channel 14, and the good product distribution channel 1531 is connected to the good product discharge channel 151. When a tire is found to be a good product during inspection, the material distribution channel 153 moves to the first position, at which point the good product distribution channel 1531 connects with the unloading channel 14. After the tire enters the good product distribution channel 1531, the material distribution channel 153 moves again to the second position, at which point the good product distribution channel 1531 connects with the good product discharge channel 151, allowing the tire to enter the good product discharge channel 151 for discharge. When a tire is found to be a defective product during inspection, the material distribution channel 153 moves to the second position, at which point the defective product distribution channel 1532 connects with the unloading channel 14. After the tire enters the defective product distribution channel 1532, the material distribution channel 153 moves again to the first position, at which point the defective product distribution channel 1532 connects with the defective product discharge channel 152, allowing the tire to enter the defective product discharge channel 152 for discharge.

[0129] In the above-mentioned scheme where the material distribution channel 153 is configured to have parallel good product distribution channel 1531 and defective product distribution channel 1532, compared with the scheme where only one channel is set for the material distribution channel 153, the maximum travel distance of the material distribution channel 153 is smaller, thereby reducing the failure caused by the long travel distance of the material distribution channel 153.

[0130] Preferably, the material dispensing mechanism 15 is provided with a mechanism to drive the material dispensing channel 153 to move. This application does not limit the type of this mechanism, and a driving mechanism such as a motor or cylinder can be used.

[0131] It should be noted that, in order to ensure that the tire's axis is horizontal, the widths of the good product discharge channel 151, the defective product discharge channel 152, and the material distribution channel 153 are set to be slightly larger than the width of the tire.

[0132] Furthermore, a material distribution sensor 154 is installed in the material distribution channel 153. When the material distribution sensor 154 detects that the tire has moved to the material distribution channel 153, the material distribution channel 153 moves and connects with the good product discharge channel 151 or the defective product discharge channel 152.

[0133] Therefore, the material distribution sensor 154 can detect whether there is a tire in the material distribution channel 153, and the material distribution channel 153 can move according to whether there is a tire in the material distribution channel 153. After the material distribution sensor 154 detects that a tire has entered the material distribution channel 153, the material distribution channel 153 moves to connect with the good product discharge channel 151 or the defective product discharge channel 152.

[0134] Furthermore, a discharge sensor 155 is installed at one end of the good product discharge channel 151 and the defective product discharge channel 152 near the material distribution position 10d. When the discharge sensor 155 detects that a tire has entered the good product discharge channel 151 or the defective product discharge channel 152, the material distribution channel 153 moves and connects with the unloading channel 14 to prepare for the material distribution and discharge operation of the next tire.

[0135] Therefore, the discharge sensor 155 can detect whether a tire has entered the good product discharge channel 151 or the defective product discharge channel 152. When the discharge sensor 155 detects that a tire has entered the good product discharge channel 151 or the defective product discharge channel 152, it means that the tire has left the distribution channel 153. Thus, the distribution channel 153 can move according to whether the tire has entered the good product discharge channel 151 or the defective product discharge channel 152. After the discharge sensor 155 detects that a tire has entered the good product discharge channel 151 or the defective product discharge channel 152, the distribution channel 153 moves to connect with the unloading channel 14.

[0136] In some embodiments, such as Figures 13-15 As shown, a material distribution sensor 154 is provided in the material distribution channel 153. At the same time, a discharge sensor 155 is provided at one end of the good product discharge channel 151 and the defective product discharge channel 152 near the material distribution position 10d.

[0137] It is understandable that when the material distribution sensor 154 and the discharge sensor 155 simultaneously detect a signal containing a tire, it means that the tire is obstructed from being discharged into the good product discharge channel 151 and the defective product discharge channel 152, causing the tire to accumulate sequentially from the good product discharge channel 151 or the defective product discharge channel 152 to the material distribution channel 153.

[0138] This allows the sensor to simultaneously detect signals from the tires via the material distribution sensor 154 and the discharge sensor 155, thus determining whether there is a fault in the tires being discharged into the good product discharge channel 151 and the defective product discharge channel 152.

[0139] In some specific embodiments, such as Figure 6 , Figure 8 As shown, the detection device also includes a material arrival sensor 134. When the material arrival sensor 134 detects that the tire has entered the detection position 10c, the detection device detects the tire.

[0140] Therefore, the detection device can perform detection operations based on whether a tire is present, enabling the detection device to automatically start tire detection.
