Description

Technical Field

[0001] This application relates to the field of tire stacking technology, and more specifically, to a tire stacking mechanism. Background Technology

[0002] Tires are round and prone to rolling, making them unsuitable for vertical stacking during storage. To reduce space occupation and optimize warehouse utilization, tires are generally stacked horizontally. Tires are mainly used in the automotive industry.

[0003] In related technologies, to address the issue of slight deformation of tires under horizontal stacking pressure, for example, patent CN218490387U provides a tire stacking device, including: a frame and several supporting parts. The frame is a cuboid frame structure with two adjacent open sides for storing and picking up tires. The frame is symmetrically provided with several equidistant rotating shafts, and the supporting parts are axially connected to the rotating shafts. Each supporting part includes a load-bearing plate and an auxiliary plate, which are arranged at an angle. The frame is provided with positioning blocks corresponding to the load-bearing plates, which can restrict the load-bearing plates to remain horizontal.

[0004] While the existing technical solutions described above allow for individual placement of the tires by setting up a support section, thus avoiding compression between tires, and utilize the weight of the tires to flip the support section, achieving automatic tire separation with simple operation, existing tires are generally made of rubber and weigh over ten kilograms, making them unsuitable for manual stacking. While tire clamps and other handling tools have low stacking efficiency, and although conveyor line stacking is efficient, tires are prone to misalignment during stacking, and existing correction mechanisms use multiple sets of cylinders, resulting in high costs.

[0005] In view of this, we propose a tire stacking mechanism. Utility Model Content

[0006] The purpose of this application is to provide a tire stacking mechanism that can effectively solve the problems in the prior art where existing tires are generally made of rubber and weigh more than ten kilograms, making them impossible to stack manually. Tire clamps and other handling tools have low stacking efficiency, while conveyor line stacking is efficient but tires are prone to misalignment during stacking. Existing correction mechanisms use multiple sets of cylinders for driving, which is costly.

[0007] This application provides a tire stacking mechanism, including a roller conveyor frame. A lifting mechanism is connected upwards to the outer frame of the roller conveyor frame. A control box is fixedly installed on one side of the lifting mechanism. An H-shaped fixing plate is installed at the bottom center of the roller conveyor frame, and a correction mechanism is installed above the H-shaped fixing plate. The correction mechanism includes an electric cylinder, correction rods, and fixing blocks fixed on both sides of the roller conveyor frame. Two correction rods form a group, and two groups of correction rods in a figure-eight shape are rotatably mounted on the fixing blocks. Four correction rods are arranged in a rhomboid pattern, and each correction rod has a rubber post at its closest point. The bottom of the fixing block and the correction rod are coaxially connected to a connecting crank. One end of each of the two connecting cranks is rotatably connected to a sliding block. A rotating rod is rotatably connected to the middle of the bottom of the sliding block, and a rotating disk is rotatably connected to the two rotating rods at their closest points.

[0008] As an optional solution to the technical solution of this application, the lifting mechanism includes a fixed frame. The two ends of the concave fixed frame are welded to the outer frame of the roller conveyor frame. An electric push rod is provided at the top of the fixed frame. A track plate is connected to the bottom of the electric push rod. Clamping plates are symmetrically slidably arranged inside the track plate. Rubber supports are evenly arranged on the inner side of the two clamping plates that are close to each other. A bidirectional lead screw is threaded into the clamping plate. One end of the bidirectional lead screw is connected to a drive servo motor.

[0009] As an optional solution to the technical solution in this application, optical sensors are provided at symmetrical positions on the inner side of the fixing frame.

[0010] As an optional solution to the technical solution of this application, one of the sliding blocks is connected to one side of the electric cylinder, and an auxiliary rod is slidably inserted inside the other sliding block, with the other end of the auxiliary rod connected to the fixed block. The two rotating rods are symmetrically distributed around the center of the rotating disk, and the center point of the rotating disk is rotatably connected to the H fixed plate through a shaft.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0012] This application utilizes an electric cylinder starter, which drives the sliding block on one side to move laterally. This causes the two sets of connecting cranks to deform, changing the unfolding angle of the two correction rods. The included angle formed inside the two correction rods can be reduced from large to small, with the maximum unfolding angle of the two correction rods to 180 degrees. After correction, all four correction rods open to both sides simultaneously, facilitating the stacking of the tires by the lifting mechanism and pushing the sides of the tires. The rotating disk rotates and is linked to the sliding block on the other side via a rotating rod, causing the two sets of correction rods to move synchronously. Therefore, this effectively solves the problem that although the conveyor line stacking is efficient, the tires are prone to positioning misalignment during stacking, and the existing correction mechanism uses multiple sets of cylinders, resulting in high costs. This allows for stacking after center positioning correction of the tire position, ensuring vertical and neat stacking without deviation in the stacking direction.

[0013] This application utilizes a lifting mechanism where the clamping plates descend first, placing the original tires onto the bottom tire. Then, the two clamping plates move away from each other and continue descending, clamping the bottom tire with rubber supports. Finally, the clamping plates rise, enabling rapid stacking of tires. In conjunction with a correction mechanism, sensors provide real-time position signal feedback, and a controller dynamically controls the motor's start and stop, achieving precise tire positioning and automated conveying processes.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 and Figure 4 This application discloses a tire stacking mechanism including a roller conveyor frame 110. A lifting mechanism 120 is connected upward to the outer frame of the roller conveyor frame 110. A control box 112 is fixedly installed on one side of the lifting mechanism 120. The control box 112 can control the lifting mechanism 120 to start lifting and clamping the tires, and the correction mechanism 130 can start positioning and correction. An H-fixed plate 111 is provided at the bottom of the middle part of the roller conveyor frame 110. The H-fixed plate 111 is used to support the stable assembly of the entire correction mechanism 130.

[0021] Reference Figure 3 and Figure 4 A correction mechanism 130 is provided above the H-fixed plate 111. The correction mechanism 130 includes an electric cylinder 135, correction rods 137, and fixed blocks 134 fixed on both sides of the roller conveyor frame 110. Two correction rods 137 form a group, and two groups of correction rods 137 in a figure-eight shape are rotatably mounted on the fixed blocks 134. The four correction rods 137 are distributed in a diamond shape, and each correction rod 137 has a rubber post at its closest end. The bottom end of the fixed block 134 and the correction rods 137 are coaxially connected to a connecting crank rod 131. One end of the two connecting crank rods 131 is rotatably connected to a sliding block 138. The middle of the bottom end of the sliding block 138 is rotatably connected to a rotating rod 133. The two rotating rods 133 are rotatably connected to a rotating disk 132 at their closest ends. One sliding block 138 is connected to one side of the electric cylinder 135, and an auxiliary rod 136 is slidably inserted inside the other sliding block 138. The other end of the auxiliary rod 136 is connected to the fixed block 134. The fixed block 134 is connected, and the two rotating rods 133 are symmetrically distributed around the center of the rotating disk 132. The center point of the rotating disk 132 is vertically connected to the H fixed plate 111 through the shaft. The electric cylinder 135 is started, which drives the sliding block 138 on one side to move laterally, causing the two sets of connecting crank rods 131 to deform and change the unfolding angle of the two correction rods 137. This allows the included angle formed inside the two correction rods 137 to change from large to small. The maximum unfolding angle of the two correction rods 137 to both sides is 180 degrees. After correction, the four correction rods 137 open to both sides at the same time, which facilitates the stacking of the lifting mechanism 120 and pushes the side of the tire. The rotating disk 132 is rotated and linked to the sliding block 138 on the other side through the rotating rod 133, which slides on the auxiliary rod 136, so that the two sets of correction rods 137 move synchronously. After the tire position is centered and corrected inward, the tires are stacked to ensure that the vertical stacking is neat and the tire stacking does not deviate from the direction.

[0022] Reference Figure 1 and Figure 2The lifting mechanism 120 includes a fixed frame 121. The two ends of the concave fixed frame 121 are welded to the outer frame of the roller conveyor frame 110. An electric push rod 122 is provided at the top of the fixed frame 121. The bottom end of the electric push rod 122 is connected to a track plate 123. Clamping plates 126 are symmetrically slidably arranged inside the track plate 123. Rubber supports 125 are evenly arranged on the inner side of the two clamping plates 126 that are close to each other. A double-acting screw 124 is threaded into the clamping plate 126. One end of the double-acting screw 124 is connected to a drive servo motor. At this time, the correction mechanism 130 is in a non-working state. The electric push rod 122 is activated, causing the track plate 123 to drive the two sets of clamping plates 126 up and down. The lifting motion involves a two-way lead screw 124 driven by a motor to first clamp the outer tire, then lift multiple outer tires upwards. After lifting, the outer tires continue to be transported on the roller conveyor 110 to the correction mechanism 130. The correction mechanism 130 corrects the tires, and then the stacking continues. The clamping plate 126 first descends, and the two clamping plates 126 place the original outer tires on the bottom outer tire. Then the two clamping plates 126 move away from each other and continue to descend, clamping the bottom outer tire with the rubber support 125. Then the clamping plate 126 rises. The number of stacked tires does not exceed 5 to avoid wear and tear on the outer tires. Five outer tires are transported and stacked in a group, and then transported by a forklift at the end of the roller conveyor 110.

[0023] Reference Figure 2 Optical sensors 113 are symmetrically positioned on the inner side of the fixed frame 121. The optical sensors 113 detect and position the tire. When the outer tire blocks the light beam, a signal is triggered. After a set delay of several seconds, the tire is determined to have reached the designated position, and the conveyor roller stops conveying. The sensor signal is transmitted to the PLC controller inside the control box 112. The controller sends a command to the motor driver to drive the conveyor roller motor to stop rotating, and the outer tire stops moving.

[0024] The roller conveyor 110 is started, and the conveyor rollers transport the tires: after the tire alignment and stacking are completed, the controller receives the operation completion signal, restarts the motor, and the conveyor rollers continue to run.

[0025] Key logic: By using sensors to provide real-time feedback of position signals, the controller dynamically controls the start and stop of the motor, thereby achieving precise tire positioning and automating the delivery process.

[0026] In summary, when the tire stacking mechanism disclosed in this application is in use, the electric cylinder 135 is activated, driving the sliding block 138 on one side to move laterally, causing the two sets of connecting cranks 131 to deform, changing the unfolding angle of the two correction rods 137, so that the included angle formed inside the two correction rods 137 can be reduced from large to small, pushing the side of the tire. The rotating disk 132 rotates and is linked to the sliding block 138 on the other side through the rotating rod 133, which slides on the auxiliary rod 136, so that the two sets of correction rods 137 move synchronously, correcting the position of the tires inward before stacking, ensuring that the vertical stacking is neat and does not deviate from the direction. When the electric push rod 122 is activated, the track plate 123 drives the two sets of clamping plates 126 to move up and down. The bidirectional screw 124, driven by the motor, can first clamp the outer tire, and then drive multiple outer tires to rise. After rising, the outer tires continue to be transported on the roller conveyor frame 110 to the position of the correction mechanism 130. The correction mechanism 130 corrects the tires, and then the stacking continues. The clamping plates 126 first descend, and the two clamping plates 126 place the original outer tires on the bottom outer tires. Then the two clamping plates 126 move away from each other and continue to descend. The bottom outer tires are clamped by the rubber support 125. Then the clamping plates 126 rise. The number of stacked tires does not exceed 5 to avoid wear on the outer tires. Five outer tires are transported and stacked in a group, and then transported by forklift at the end of the roller conveyor frame 110.
