Description

Technical Field

[0001] This invention relates to the technical field of tire manufacturing, and in particular to a tire blank feeding trolley with a tire storage device. Background Technology

[0002] In the tire manufacturing industry, tire blanks, as semi-finished products before vulcanization, are soft and easily deformed, requiring safe temporary storage and transportation between the molding and vulcanization processes. Currently, the industry commonly uses dedicated tire blank trolleys to accomplish this logistics task. These trolleys are typically equipped with tire storage devices to support the tire blanks, preventing deformation due to pressure or impact during storage and transportation, which could affect the final tire product quality.

[0003] Existing tire blank trolley technologies primarily focus on addressing the issue of tire blank support adaptability. For example, Chinese utility model patent CN218785567U discloses a tire blank storage and transport trolley that uses fixed and adjustable rods on both sides of the frame to support the tire blanks with a flexible support belt. This solution allows for manual adjustment of the effective length of the support belt by changing the position of the adjustable rod on the adjustment plate, thereby accommodating tire blanks of different diameters. This reduces the number of dedicated trolleys required due to product diversification and lowers equipment costs.

[0004] However, existing technological solutions still have limitations in practical applications, hindering further improvements in production automation efficiency. First, these trolleys move freely during operation, lacking a rigid and reliable positioning and connection mechanism with fixed equipment (such as molding machines and vulcanizing machines). Loading (removing tires from the molding machine) or unloading (feeding tires to the vulcanizing machine) operations require manual repositioning and adjustment of the trolley to align with the workstation, or the use of overhead cranes for hoisting. This operating mode is not only inefficient and labor-intensive, but also makes it difficult to guarantee positioning accuracy, easily leading to misplacement or damage to the tire blank, posing quality risks. Second, because the trolley does not form a stable integrated workstation with the preceding and following process equipment, it may shift when subjected to the pushing, pulling forces or vibrations generated during tire blank loading or unloading, affecting the stability and repeatability of the operation, making it difficult to achieve fully automated and unmanned operation. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a tire preform feeding trolley with a tire retainer.

[0006] This invention provides a tire feeding trolley with a tire holder, comprising a moving trolley, a push handle, self-locking casters, a controller, and a tire holder. The moving trolley has a push handle at its top and a set of self-locking casters at each of its four bottom corners. The controller is located at the top of the moving trolley. The trolley also includes a moving component and a locking component. The moving component is mounted on the top of the moving trolley, and the tire holder is mounted on the moving component. The moving component is used for adjusting the position of the tire holder. The locking component is mounted on the moving trolley and is used to lock the moving trolley and the moving component. Both the moving component and the locking component are electrically connected to the controller. During operation, staff push the mobile trolley with a push handle, allowing it to move in position with the help of four sets of self-locking casters. Then, staff operate the controller to lock the mobile trolley to the outlet of the tire forming machine while simultaneously releasing the locking mechanism from the mobile component. The forming machine then transports the formed tire blanks to the inside of the tire storage container. Staff use the controller to operate the mobile component to adjust the position of the tire storage container, enabling it to load multiple sets of tire blanks onto vehicles. Finally, the locking mechanism releases the lock on the mobile trolley while simultaneously locking the mobile component, improving the stability of the tire storage container.

[0007] Preferably, the moving assembly includes a servo motor, upright plates, guide rods, lead screws, a moving base, a first slider, a second slider, and positioning holes. The servo motor is mounted on the top of the moving trolley. Two sets of upright plates are fixedly mounted on the top of the moving trolley. Two sets of guide rods are fixedly installed between the two sets of upright plates. The lead screw is rotatably mounted between the two sets of upright plates. The output end of the servo motor is connected to one end of a lead screw. A tire holder is mounted on the top of the moving base. A first slider and a second slider are mounted on the bottom of the moving base. The second slider has a positioning hole. The first slider is slidably connected to the guide rod, and the second slider is threadedly connected to the lead screw. The servo motor is electrically connected to the controller. When the moving trolley is connected to the molding machine via the locking assembly, the locking assembly is simultaneously moved away from the positioning hole. Then, the operator operates the rotation direction of the servo motor through the controller, causing the lead screw, in cooperation with the two sets of guide rods, to cause the moving base to adjust the position of the tire holder. This allows the tire holder to store multiple sets of tire blanks, improving operational convenience. During loading, the moving trolley does not need to be adjusted, improving loading stability.

[0008] Preferably, the locking assembly includes a mounting base, a corner electric cylinder, a locking block, a guide rod, a moving block, a spring, a connecting rod, a top plate, an insert rod, and a positioning monitoring assembly. The top of the moving trolley has a groove, in which a guide rod is fixedly mounted. The moving block is slidably connected to the guide rod. An insert rod is mounted on the moving block, and a spring is fitted around the outside of the guide rod. A connecting rod is mounted on the end of the moving block away from the spring, and is slidably connected to the moving trolley. A top plate is mounted on the end of the connecting rod away from the moving block. A set of mounting bases is provided on each side of the moving trolley, and a set of corner electric cylinders is fixedly mounted on each set of mounting bases. A locking block is provided on the moving end of each set of corner electric cylinders. The insert rod is adapted to the positioning hole. The positioning monitoring assembly is installed between the second slider and the moving block for aligning the insert rod with the positioning hole. Both the corner electric cylinder and the positioning monitoring assembly are electrically connected to the controller. When the moving trolley moves via four sets of self-locking casters, the insert rod inserts into the positioning hole to prevent the moving base from moving. When the moving trolley stops at the molded... At the machine's discharge port, operators use the controller to shorten two sets of corner electric cylinders, causing two sets of locking blocks to engage the molding machine. This brings the moving trolley close to the molding machine's outlet, while the side wall of the molding machine presses against the top plate. This causes the connecting rod, with the help of the guide rod, to move the moving block and the insert rod away from the positioning hole, locking the moving trolley to the molding machine and unlocking the second slider. Afterwards, operators use the controller to adjust the positions of the moving seat and the tire holder using the servo motor. Once loading is complete, operators align the positioning hole and the insert rod again. After the positioning monitoring component detects that the positioning hole and the insert rod are aligned, operators use the controller to extend the two sets of corner electric cylinders. If the positioning monitoring component does not detect that the positioning hole and the insert rod are aligned, operators cannot extend the two sets of corner electric cylinders. After the corner electric cylinders extend, the moving trolley is unlocked from the molding machine, and the moving block, under the action of the spring force, moves the insert rod back into the positioning hole, re-locking the moving block and improving the stability of transportation.

[0009] Preferably, the positioning monitoring component includes a first fixed base, a photoelectric signal transmitter, a second fixed base, and a photoelectric signal receiver. The first fixed base is installed on the top of the moving block, and the photoelectric signal transmitter is mounted on the first fixed base. The second fixed base is installed on the second slider, and the photoelectric signal receiver is mounted on the second fixed base. Both the photoelectric signal transmitter and the photoelectric signal receiver are electrically connected to the controller. When the photoelectric signal receiver coincides with the photoelectric signal transmitter, the photoelectric signal receiver receives the photoelectric signal emitted by the photoelectric signal transmitter. The operator can operate the corner electric cylinder to extend or shorten through the controller. When the servo motor drives the moving base to adjust its position, and the photoelectric signal transmitter and the photoelectric signal receiver are in a misaligned state, the operator cannot operate the corner electric cylinder to extend through the controller. After the moving base is reset, the photoelectric signal receiver receives the photoelectric signal from the photoelectric signal transmitter, and the operator can operate the corner electric cylinder to extend through the controller, thereby separating the moving trolley from the molding machine and inserting the rod into the positioning hole.

[0010] Preferably, the device also includes a positioning seat, reinforcing ribs, bolts, and a guide wheel array. The positioning seat is fixedly installed on the top of the mobile trolley by multiple sets of bolts. The positioning seat has reinforcing ribs inside and a guide wheel array on it. The guide wheel array makes rolling contact with one end of the tire storage device. When the mobile seat moves the tire storage device to adjust its position, the guide wheel array makes rolling contact with one end of the tire storage device. When the tire is placed inside the tire storage device, the inertia of the tire will cause the tire storage device to sway back and forth. With the cooperation of the positioning seat, the guide wheel array prevents the tire storage device from shaking, improves stability, and extends its service life.

[0011] Preferably, it also includes side plates, a fixed shaft, a U-shaped frame, a sealing plate, and a traction ring. One end of the mobile trolley is provided with two sets of side plates, and a fixed shaft is fixedly provided between the two sets of side plates. The U-shaped frame is fitted on the outside of the fixed shaft, and a sealing plate is provided at the top of the U-shaped frame. A traction ring is fixed at the top of the sealing plate. In the normal state, the U-shaped frame is made vertical, and then the U-shaped frame is moved downward. The fixed shaft is at the top of the inner side of the U-shaped frame, and at the same time, the side wall of the U-shaped frame contacts the side wall of the mobile trolley, realizing the fixation and storage of the U-shaped frame. When the tractor needs to connect to the traction ring, the operator raises the U-shaped frame so that the fixed shaft contacts the bottom end of the inner side wall of the U-shaped frame. Then the U-shaped frame can be freely adjusted in angle, so that the tractor and the traction ring can be hooked and connected, improving the convenience and flexibility of operation.

[0012] Preferably, it also includes a first buffer pad, which is provided on the top plate; the top plate, in cooperation with the first buffer pad, comes into contact with the side wall of the molding machine, reducing wear and increasing service life.

[0013] Preferably, it also includes a second buffer pad, with each set of the clamping blocks having a set of second buffer pads; the clamping blocks are engaged with the molding machine through the second buffer pads, reducing frictional wear and improving service life.

[0014] Preferably, it also includes a handle cover, which is fitted onto the outer wall of the push handle; the operator grips the push handle with the handle cover to reduce the occurrence of slippage.

[0015] Preferably, the servo motor is a servo self-locking motor.

[0016] The beneficial effects of this invention are as follows: In use, the operator pushes the mobile trolley with a push handle, thereby moving the trolley in position with the cooperation of four sets of self-locking casters. Then, the operator operates the controller to lock the mobile trolley to the outlet of the tire forming machine, while simultaneously releasing the locking component from the moving component. Afterward, the forming machine transports the formed tire blanks to the inside of the tire storage container. The operator operates the moving component through the controller to adjust the position of the tire storage container, thereby enabling the tire storage container to load multiple sets of tire blanks onto the vehicle. Afterward, the operator operates the locking component to release the lock on the mobile trolley while simultaneously locking the moving component, thus improving the stability of the tire storage container.

[0023] In this embodiment, when the mobile trolley 101 moves via four sets of self-locking casters 103, the insert rod 309 is inserted into the positioning hole 208 to prevent the moving seat 205 from moving. When the mobile trolley 101 stops at the outlet of the molding machine, the operator operates the two sets of corner electric cylinders 302 to shorten via the controller 104, thereby causing the two sets of locking blocks 303 to lock the molding machine, thus making the mobile trolley 101 close to the outlet of the molding machine. At the same time, the side wall of the molding machine presses against the top plate 308, thereby causing the connecting rod 307, with the cooperation of the guide rod 304, to move the moving block 305 to drive the insert rod 309 away from the positioning hole 208, realizing the movement of the mobile trolley 101 and the molding machine outlet. While the machine is locked, the insertion rod 309 unlocks the second slider 207. The operator uses the controller 104 to operate the rotation direction of the servo motor 201, causing the lead screw 204, in conjunction with the two sets of guide rods 203, to move the moving seat 205 and adjust the position of the tire holder 105. This allows the tire holder 105 to store multiple sets of tire blanks. After loading, the servo motor 201 adjusts the position of the moving seat 205. When the photoelectric signal receiver 404 coincides with the photoelectric signal transmitter 402, the photoelectric signal receiver 404 receives the photoelectric signal emitted by the photoelectric signal transmitter 402. The operator can then use the controller 104 to... By operating the angle electric cylinder 302 to extend or retract, the operator realigns the positioning hole 208 with the insertion rod 309. After the angle electric cylinder 302 extends, the moving trolley 101 is unlocked from the molding machine. Simultaneously, the moving block 305, under the elastic force of the spring 306, drives the insertion rod 309 to re-insert into the positioning hole 208, thus relocking the moving block 305. When the moving seat 205 moves the tire holder 105 to adjust its position, the guide wheel row 504 rolls in contact with one end of the tire holder 105. When the tire blank is placed inside the tire holder 105, the inertia of the tire blank will cause the tire holder 105 to sway back and forth. With the cooperation of the positioning seat 501, the wheel row 504 prevents the tire holder 105 from shaking. In the normal state, the U-shaped frame 603 is made vertical, and then the U-shaped frame 603 is moved downward. The fixed shaft 602 is on the top inner side of the U-shaped frame 603, and at the same time, the side wall of the U-shaped frame 603 contacts the side wall of the moving trolley 101, so as to fix and store the U-shaped frame 603. When the tractor needs to connect to the towing ring 605, the operator raises the U-shaped frame 603 so that the fixed shaft 602 contacts the bottom end of the inner side wall of the U-shaped frame 603. Then the U-shaped frame 603 can be freely adjusted in angle, so that the tractor and the towing ring 605 can be hooked and connected.

[0024] The main functions achieved by this invention are: 1. While the locking block 303 is locked with the molding machine, the top plate 308 moves the insertion rod 309 away from the positioning hole 208, thereby unlocking the moving seat 205; 2. While the locking block 303 unlocks from the molding machine, the photoelectric signal receiver 404 and the photoelectric signal transmitter 402 perform detection to achieve the alignment of the insertion rod 309 with the positioning hole 208, thereby locking the insertion rod 309 onto the moving seat 205.
