[0002] The tire catcher can pick up and release a newborn tire. The tire catcher includes claws and a drive assembly that drives the claws to move. The tire catcher needs to rotate during operation. The circuits that supply power to the drive assembly or the air supply lines are easily tangled and pulled during the rotation of the tire catcher, which will affect the normal operation of the drive assembly. Summary of the Invention

[0003] In view of this, the present invention provides a rotary tire gripper for a tire vulcanizing machine to solve the problem that the circuit supplying power to the drive assembly or the air supply line is easily entangled and pulled during the rotation of the tire gripper.

[0004] This invention provides a rotary tire gripper for a tire vulcanizing machine, comprising:

[0005] tray;

[0006] A tire gripper includes a tire gripping plate, which is rotatably mounted on the tray and can rotate around its axis. The tire gripping plate is provided with a plurality of claws and a first drive assembly. The first drive assembly can drive the plurality of claws to open or close relative to each other. The first drive assembly is connected to a power supply circuit or an air circuit.

[0007] A rotary cable carrier device includes a chain and a track assembly. The chain has a fixed end and a movable end. The fixed end is fixed relative to the pallet, and the movable end rotates with the gripper. The chain is located on the track assembly and is used for routing the power supply circuit or the air circuit.

[0008] Beneficial effects: The first drive component can drive several of the claw plates to open or close to each other, thereby realizing automatic picking and placing of green tires. By setting a rotary drag chain device, which includes a chain and a track component, the track component can guide and limit the movement of the chain. The chain is used to run the power supply circuit or air circuit, which can prevent the power supply circuit or air circuit of the drive component from getting tangled and pulled during the rotation of the tire grabber.

[0009] In one optional embodiment, the track assembly includes an outer rail, an inner rail, an outer partition, and an inner partition. The outer rail includes a first arc-shaped wall panel, the inner rail includes a second arc-shaped wall panel, and both the outer partition and the inner partition are arc-shaped. The radius of the first arc-shaped wall panel is R1, the radius of the outer partition is R2, the radius of the inner partition is R3, and the radius of the second arc-shaped wall panel is R4, where R1 > R2 > R3 > R4. The outer rail and the inner partition are fixed relative to the tray, and at least a portion of the outer rail and the inner partition are distributed on both sides of a straight line passing through the center of the gripping tray. The outer partition and the inner rail are respectively connected to the gripping tray, and at least a portion of the outer partition and the inner rail are distributed on both sides of a straight line passing through the center of the gripping tray. The fixed end is fixed to the inner side of the first end of the outer rail, and the movable end of the chain is fixed to the side of the first end of the inner rail facing the outer rail.

[0010] The placenta grabber has an initial position, in which the chain is folded in half in the middle and the first end of the inner frame is close to the first end of the outer frame;

[0011] After the placenta is rotated from the initial position to the first direction by a preset angle, the chain is located between the inner rail and the inner partition.

[0012] After the placenta is rotated from its initial position to the second direction by a preset angle, the chain is positioned between the outer partition and the outer rail.

[0013] Beneficial effects: When the placenta gripper is in its initial position, the chain is folded in half, positioned between the outer and inner rails.

[0060] The following is combined Figures 1 to 12 The following describes embodiments of the present invention.

[0061] According to an embodiment of the present invention, in one aspect, a rotary tire gripper for a tire vulcanizing machine is provided, comprising a tray 1, a tire gripper, and a rotary cable chain device.

[0062] The tire gripper includes a tire gripping plate 2, which is rotatably mounted on a tray 1 and can rotate around its axis. The tire gripping plate 2 is provided with several claws 21 and a first drive assembly 22. The first drive assembly 22 can drive the claws 21 to open or close relative to each other. The first drive assembly 22 is connected to a power supply circuit or an air circuit. The rotary cable chain device includes a chain 8 and a track assembly. The chain 8 has a fixed end 81 and a movable end 82. The fixed end 81 is fixed relative to the tray 1, and the movable end 82 rotates with the tire gripping plate 2. The chain 8 is located on the track assembly and is used for routing power supply circuits or air circuits.

[0063] In this embodiment, the first drive component 22 can drive a plurality of claw plates 21 to open or close to each other, thereby realizing automatic picking and placing of green tires. By setting a rotary drag chain device, which includes a chain 8 and a track component, the track component can guide and limit the movement of the chain 8. The chain 8 is used for power supply circuit or air circuit wiring, which can prevent the power supply circuit or air circuit of the drive component from getting tangled and pulled during the rotation of the tire grabber.

[0064] In one embodiment, the track assembly includes an outer rail 91, an inner rail 92, an outer partition 93, and an inner partition 94. The outer rail 91 includes a first arc-shaped wall panel 911, and the inner rail 92 includes a second arc-shaped wall panel 921. Both the outer partition 93 and the inner partition 94 are arc-shaped. The radius of the first arc-shaped wall panel 911 is R1, the radius of the outer partition 93 is R2, the radius of the inner partition 94 is R3, and the radius of the second arc-shaped wall panel 921 is R4, where R1 > R2 > R3 > R4. The outer rail 91 and the inner partition 94 are fixed relative to the tray 1, and at least a portion of the outer rail 91 and the inner partition 94 are distributed on both sides of a straight line passing through the center of the gripping tray 2. The outer partition 93 and the inner rail 94 are arc-shaped. 2 are respectively connected to the placenta 2, and at least part of the outer partition 93 and the inner rail 92 are distributed on both sides of a straight line passing through the center of the placenta 2. The fixed end 81 is fixed to the inner side of the first end of the outer rail 91, and the movable end 82 of the chain 8 is fixed to the side of the first end of the inner rail 92 facing the outer rail 91. The placenta 2 has an initial position. In the initial position, the chain 8 is folded in the middle, and the first end of the inner rail 92 is close to the first end of the outer rail 91. After the placenta 2 is rotated from the initial position to the first direction by a preset angle, the chain 8 is located between the inner rail 92 and the inner partition 94. After the placenta 2 is rotated from the initial position to the second direction by a preset angle, the chain 8 is located between the outer partition 93 and the outer rail 91.

[0065] In this embodiment, when the placenta 2 is in its initial position, the chain 8 is folded in half, and the chain 8 is located between the outer rail 91 and the inner rail 92. When the placenta 2 rotates from its initial position in the first direction, the inner rail 92 drives the chain 8 to move together, and the chain 8 is located between the inner rail 92 and the inner partition 94. The inner partition 94 and the inner rail 92 limit and guide the two sides of the chain 8. When the placenta 2 rotates from its initial position in the second direction, the inner rail 92 drives the chain 8 to move together, and the outer partition 93 gradually rotates to one side of the outer rail 91. The chain 8 is located between the outer rail 91 and the outer partition 93, and the outer rail 91 and the outer partition 93 limit and guide the two sides of the chain 8. Therefore, the movement trajectory of the chain 8 is limited, which can prevent the power supply circuit of the drive component from getting tangled and pulled during the rotation of the placenta 2.

[0066] Specifically, such as Figure 7 and Figure 8 As shown, the first arc-shaped wall panel 911 of the outer rail 91, the second arc-shaped wall panel 921 of the inner rail 92, the outer partition 93 and the inner partition 94 are all semi-circular structures. The positions of the outer rail 91 and the inner partition 94 are fixed and they are arranged opposite each other. The outer partition 93 and the inner rail 92 are opposite each other and rotate with the gripper 2.

[0067] In one specific embodiment, the preset angle is 180°. For example... Figure 9 and Figure 10 As shown, when the placenta 2 rotates 180° from its initial position in the first direction (counterclockwise), the chain 8 is positioned between the inner rail 92 and the inner partition 94; Figure 11 and Figure 12 As shown, when the placenta 2 rotates 180° from its initial position in the second direction (clockwise), the chain 8 is located between the outer frame 91 and the outer partition 93.

The protective cover 10 is provided outside the support assembly, and the outer rail 91 and the inner partition 94 are fixedly connected to the protective cover 10.

[0070] In this embodiment, the support assembly enables the smooth rotation of the gripping placenta 2. The outer ring gear 34 meshes with a drive gear, and the second drive assembly 35 drives the drive gear to rotate, enabling the gripping placenta 2 to rotate relative to the tray 1. After gripping the green fetus, it can drive the green fetus to rotate. By setting a protective cover 10, the protective cover 10 can protect the support assembly. The outer rail 91 and the inner partition 94 are fixedly connected to the protective cover 10, and the outer rail 91 and the inner partition 94 do not rotate with the gripping placenta 2.

When the drive plate 24 rotates relative to the gripping plate 2, the guide hole 241 can guide the guide block 211 to move, so that the claw 21 moves radially.

[0077] In this embodiment, the guide hole 241 and the guide block 211 are provided to guide the movement direction of the claw 21.

[0078] Specifically, the claw 21 is provided with a slider 212, and the slider 212 and the guide rail 23 are connected by sliding to realize the radial movement of the claw 21 along the guide rail 23.

[0081] And / or, the drive plate 24 is rotatably connected to the gripper plate 2 via bearings;

[0082] And / or, the guide hole 241 is arc-shaped and forms an angle with the circumference of the drive plate 24;

[0083] And / or, several claw plates 21 are evenly distributed circumferentially;

[0084] And / or, some of the claw pieces 21 extend from the bottom of the tray 1;

[0085] And / or, both the placenta 2 and the drive plate 24 are set horizontally;

[0086] And / or, the guide block 211 is clearance-fitted with the two long sides of the guide hole 241;

[0087] And / or, the first drive assembly 22 is configured as a retractable structure; one end of the first drive assembly 22 is hinged to the drive plate 24, and the other end of the first drive assembly 22 is hinged to the gripper 2.

[0088] Specifically, please refer to Figure 2 and Figure 3 The drive plate 24 is provided with an inner hole 242 coaxially arranged therewith; the gripping plate 2 is provided with four guide wheels 25 evenly distributed in the circumference. The wheel surface of the guide wheel 25 abuts against the inner wall surface of the inner hole 242.

[0095] The braking component is located on the tray 1 and can position the gripping plaque 2 to the tray 1; the rotation detection component 5 is used to measure the rotation position of the gripping plaque 2; the barcode recognition component 6 is used to identify the position of the barcode on the side of the fetus; the controller is connected to the first drive component 22, the second drive component 35, the braking component, the rotation detection component 5 and the barcode recognition component 6 respectively.

[0096] The braking assembly positions the tire gripper 2 and the tray 1. When the green tire rotates to the appropriate position, the braking assembly positions the green tire to prevent accidental rotation of the tire gripper, reducing safety risks and ensuring that the green tire is placed in the vulcanizing machine at a specific rotation angle, ensuring the accurate position of the QR code on the sidewall of the vulcanized tire. After the vulcanized QR code is affixed to the green tire, the barcode recognition assembly 6 is used to identify the position of the vulcanized QR code on the sidewall of the green tire. The measurement information from the rotation detection assembly 5 and the barcode recognition assembly 6 can be sent to the controller, which then controls the first drive assembly 22, the second drive assembly 35, and the braking assembly to operate in an orderly manner, enabling automation and unattended operation of the entire vulcanization process.

[0097] In one specific embodiment, the barcode recognition component 6 comprises an electrical component 602 capable of recognizing the location of a QR code and a support frame 601, wherein the support frame 601 is connected to the cross arm 7 or the tray 1 by screws.

[0098] In one specific embodiment, the barcode recognition component 6 includes several visual sensors that are evenly distributed around the placenta 2 in the circumference, and are capable of identifying the position of the vulcanized QR code on the green tire in real time.

[0099] It should be noted that, in addition to QR codes, barcodes can also be barcodes.

[0100] In one embodiment, the braking assembly includes a cylinder 41, the piston rod of the cylinder 41 having a toothed block 42 at its end; the cylinder 41 is capable of moving the toothed block 42 between a first position and a second position; in the first position, the toothed block 42 engages with an outer ring gear 34; in the second position, the toothed block 42 disengages from the outer ring gear 34.

[0101] In this embodiment, in the first position, the toothed block 42 engages with the outer ring gear 34 to position the pallet 2 and the tray 1; in the second position, the toothed block 42 disengages from the outer ring gear 34, and the pallet 2 can rotate relative to the tray 1.

[0102] In one embodiment, the rotation detection assembly 5 includes an electrical sensing element 51 disposed on the tray 1 and a detection switch 53 fixed to the outer frame 91, and the gripping plate 2 is provided with a rotating component 52 that matches the electrical sensing element 51.

[0103] And / or, the second drive assembly 35 includes a motor fixed to the tray 1;

[0104] And / or, the controller is set to PLC.

[0105] Specifically, please refer to Figures 3-4 The rotation detection component 5 preferably includes an electrical sensing element 51 disposed on the tray 1 and a detection switch 53 fixed to the outer frame 91. The gripping plate 2 is provided with a rotating component 52 that matches the electrical sensing element 51, which can measure the rotation angle of the gripping plate 2 in real time. Specifically, the electrical sensing element 51 can be a displacement sensor, a proximity switch or an electronic ruler.

[0106] The detection switch 53 is specifically located near the fixed end 81 of the chain 8, and the chain 8 will pass under the detection switch 53 during the movement.

[0107] The controller is preferably a PLC, located in the electrical cabinet on one side of the vulcanizing machine, and is used to collect, store and feed back signals from various electrical components.

[0108] In one embodiment, a cross arm 7 is also included, and a tray 1 is fixed to the cross arm 7; a tie rod 71 is provided between the outer edge of the tray 1 away from the cross arm 7 and the cross arm 7.

[0109] In this embodiment, the cross arm 7 is used to support the entire rotary tire gripper of the tire vulcanizing machine; the end of the cross arm 7 away from the tray 1 is provided with an intermediate shaft 72, and the cross arm 7 rotates around the intermediate shaft 72, which can drive the present invention to rotate around the intermediate shaft 72; a tie rod 71 is provided between the outer edge of the tray 1 away from the cross arm 7 and the cross arm 7. When gripping the green tire, since the outer side of the gripping plate 2 is subjected to greater force, the tie rod 71 can withstand the tension when gripping the green tire, so that the entire tire gripper is kept in a horizontal state.

[0110] The specific working process of the rotary tire gripper for the tire vulcanizing machine provided in this embodiment is as follows:

[0111] After the vulcanized QR code is pasted onto the green tire, the robotic arm mounted on the moving bracket moves the present invention directly above the green tire with the vulcanized QR code pasted on and then lowers it to a suitable tire-grabbing position, so that several claws 21 extend into the green tire; before grabbing the tire, the toothed block 42 is in the first position and the drive gear is in the braking state.

[0112] The first drive assembly 22 drives several claws 21 to move radially outward in sync to grab the green tire, and the robotic arm rises and moves to directly above the vulcanizing machine;

[0113] Since the position of the tire mold is fixed before the tire is vulcanized, the position of the corresponding QR code in the tire mold is fixed. The position information is input to the controller, the robot arm moves the green tire to the vulcanizing machine, the barcode recognition component 6 recognizes the position of the vulcanization QR code and feeds it back to the controller, the controller calculates the angle of rotation required for the green tire.

[0114] The toothed block 42 moves to the second position, and the second drive assembly 35 drives the drive gear to rotate, causing the gripper 2 to rotate. When the gripper 2 rotates, it drives the outer partition 93 and the inner rail 92 to rotate synchronously. Since the movable end 82 of the chain 8 is fixed to the first end of the inner rail 92, it will drive the chain 8 to move together. The rotation detection assembly measures the rotation angle of the gripper 2 in real time. When it rotates to the predetermined angle, it stops rotating. The toothed block 42 moves to the first position to position the gripper 2.

[0115] The first drive assembly 22 drives several claw plates 21 to retract radially inward in sync. The claw plates 21 close and lower the green tire. The robotic arm rises and moves the rotary tire gripper out of the vulcanizing machine, and the vulcanizing process can then begin.

[0116] The rotary tire gripper for the tire vulcanizing machine provided in this embodiment uses a first drive assembly 22 to drive several claw plates 21 to open or close, automatically picking up and placing green tires. Before placing the green tire into the vulcanizing machine, a vulcanization QR code can be easily affixed to the green tire. The barcode recognition assembly 6 can identify the position of the vulcanization QR code on the green tire, and the second drive assembly 35 drives the gripping plate 2 to rotate freely within a 360° range relative to the tray 1, accurately controlling the rotation angle of the green tire. When the rotation detection assembly 5 measures that the green tire has rotated to the appropriate position, the green tire can be placed into the vulcanizing machine for vulcanization, ensuring that the QR code is accurately vulcanized at a specific position on the side of the green tire. This achieves automation and unattended operation of the entire vulcanization process, effectively reducing safety hazards and labor intensity. Furthermore, the driving force is stable, the structure is simple, the operation is reliable, and the cost is low. Both the barcode recognition assembly 6 and the rotation detection assembly 5 cooperate with the controller to transmit the measured data information to the operator and the controller in real time, forming a closed-loop control.

[0117] The rotary tire gripper for the tire vulcanizing machine provided in this embodiment uses a number of guide wheels 25 provided on the gripping plate 2 to center the drive plate 24, and uses a number of limiting blocks 26 provided on the gripping plate 2 to limit the axial position of the drive plate 24, so as to ensure that the drive plate 24 rotates stably relative to the gripping plate 2.

[0118] The rotary tire gripper for the tire vulcanizing machine provided in this embodiment utilizes a tie rod 71 located between the horizontal arm 7 and the tray 1, which can withstand tension when gripping the green tire, ensuring that the entire tire gripper remains in a horizontal state at all times.

[0119] The rotary tire gripper for the tire vulcanizing machine provided in this embodiment has a hollow structure with a hollow cavity, which can conveniently place the green tire into the vulcanizing machine, and can also conveniently place the green tire through the bladder.

[0120] For larger engineering tires and giant tires, the tire blanks are heavy, the green tire blanks are soft, and the shape is poor, resulting in a large degree of sagging. The bladder on the vulcanizing machine is stretched in the vertical direction and the internal gas is extracted, so that the bladder contracts on the central mechanism. Large tires use large bladders, and the vertical stretch is also large. At this time, the tire gripper can be placed on the outside of the bladder to hold the tire blank firmly on the mold and then retract it.

[0121] In addition, such as Figure 1 and Figure 2 As shown, the rotary drag chain device is located at the edge of the gripping placenta 2 and is distributed around the periphery of the hollow cavity, so it does not affect the function of the hollow cavity.

[0122] The rotary tire gripper for tire vulcanizing machines provided in this embodiment can meet the needs of tires of different specifications. It is easy to operate, highly versatile, and can effectively improve the efficiency of tire loading by up to 30% and save up to 50% of the labor cost of tire loading.

[0123] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
