Description

Technical Field

[0001] This invention relates to the field of tire transport technology, and in particular to a tire transport vehicle positioning system. Furthermore, this invention also relates to a system comprising the above-described components. Background Technology

[0002] Currently, in forklift tire production lines, when moving tires from the offline line to the conveyor line, a tooling trolley is typically used to transport the tires to the side of the conveyor line, and then manual labor is required to move the tires onto the conveyor belt. With the booming development of the logistics industry and the increasing demand for forklifts, the automation level of factory production needs to be continuously improved. Therefore, robotic arms for automatically gripping tires will inevitably replace manual handling, thus freeing up labor.

[0003] Positioning the tire transporter is a prerequisite for the robotic arm to grasp the tire. Traditional mechanical positioning automatic grasping robotic arms have very high requirements for the positioning accuracy of the tire transporter. The current positioning method is mainly manual-assisted mechanical positioning, that is, the tire transporter is pushed to the designated loading position by a person and fixed and limited by a mechanical device. However, manual intervention to push the tire transporter for positioning is labor-intensive and has low work efficiency.

[0004] Therefore, how to solve the problems of high labor intensity and low work efficiency of manual-assisted mechanical positioning tire transport vehicles is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a tire transport vehicle positioning system that can achieve automatic positioning of tire transport vehicles with high positioning accuracy and efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a tire transport vehicle positioning system, including a controller, two laterally extending guide rails, and a parking proximity switch triggered by a logistics vehicle. The area between the two guide rails is a logistics vehicle parking area, which includes a parking entrance, a parking space, and a parking exit. A pusher is provided on the ground between the two guide rails for pushing the logistics vehicle from the parking entrance to the parking exit. The pusher and the parking proximity switch are both connected to the controller. When the parking proximity switch is triggered, the controller controls the pusher to stop operating.

[0007] Preferably, the system further includes an indicator light, an entrance proximity switch and an exit proximity switch for being triggered by a logistics vehicle. The indicator light, the entrance proximity switch and the exit proximity switch are all connected to the controller. When the entrance proximity switch is triggered, the indicator light indicates that the logistics vehicle enters the parking entrance. When the exit proximity switch is triggered by the logistics vehicle, the indicator light indicates that the logistics vehicle moves to the parking exit, and the trolley stops pushing the logistics vehicle.

[0008] Preferably, the trolley pusher includes a laterally extending cable chain, a sprocket that drives the cable chain to rotate in a cycle, and a motor that drives the sprocket. The cable chain is equipped with a pushing part for connecting to a logistics vehicle. The pushing part includes two push heads arranged at intervals. Each push head includes a base plate and a vertical plate that are angled together. The bent part of the push head is hinged to the cable chain. The base plate abuts against the cable chain. The front push head can only rotate backward around the hinge axis, and the rear push head can only rotate forward around the hinge axis, so that the towing pin on the logistics vehicle can be engaged between the two push heads.

[0009] Preferably, the cable chain is provided with two pushing parts, and the two ends of the cable chain are respectively the start position and the end position of the pushing parts. When one pushing part is in the start position, the other pushing part is in the end position. The trolley pusher also includes a trolley proximity switch for being triggered by the pushing parts. When the trolley proximity switch is triggered, the indicator light indicates that the two pushing parts are respectively in the start position and the end position, and the controller controls the trolley pusher to stop running.

[0010] Preferably, the first ends of both guide rails are bent outwards to form a flared parking entrance; both guide rails are provided with limiting wheels to prevent the logistics vehicle from deviating.

[0011] Preferably, when only the trolley proximity switch is triggered, the indicator light is green and constantly lit; when both the entrance proximity switch and the trolley proximity switch are triggered, the indicator light is red and constantly lit; when only the parking proximity switch is triggered by the logistics vehicle, the indicator light is yellow and constantly lit; when both the parking proximity switch and the trolley proximity switch are triggered simultaneously, the indicator light is yellow and flashing; when both the exit proximity switch and the trolley proximity switch are triggered, the indicator light is green and flashing.

[0012] Preferably, the system also includes a laser rangefinder for detecting whether the logistics vehicle has come to a complete stop and a photoelectric switch assembly for detecting whether there is a towing vehicle in the parking area of ​​the logistics vehicle. Both the laser rangefinder and the photoelectric switch are connected to the controller. When the entrance proximity switch is triggered, the measurement value of the laser rangefinder is stable, and the photoelectric switch assembly does not detect a towing vehicle, the controller controls the pusher to start and drive the logistics vehicle from the parking entrance to the parking space.

[0013] Preferably, the photoelectric switch assembly includes a plurality of photoelectric switches disposed above the guide rail and a receiving board for receiving signals from each of the photoelectric switches. The photoelectric switches are arranged at a lateral interval, and the interval between two adjacent photoelectric switches is less than the length of the tractor. The photoelectric switches and the corresponding receiving boards are located on the left and right sides of the logistics vehicle parking area, respectively.

[0014] Preferably, the system also includes a robotic arm for transferring the tires on the logistics vehicle to a preset position. The robotic arm is connected to the controller. When the parking proximity switch is triggered by the logistics vehicle, the controller controls the robotic arm to start. After the robotic arm completes the gripping operation, the pusher starts and drives the logistics vehicle from the parking space to the parking exit.

[0015] Preferably, the controller stores tire demand information and tire position information on each logistics vehicle. A barcode scanner is provided on the guide rail near the parking proximity switch to scan the vehicle code on the logistics vehicle to obtain tire position information. When the parking proximity switch is triggered by the logistics vehicle, the barcode scanner scans the vehicle code on the logistics vehicle and obtains the position information. The robotic arm then grabs the tires according to the tire demand information and the position information.

[0016] The tire transport vehicle positioning system provided by the present invention includes a controller, two laterally extending guide rails, and a parking proximity switch triggered by a logistics vehicle. The area between the two guide rails is a parking area for the logistics vehicle, which includes a parking entrance, a parking space, and a parking exit. A pusher for pushing the logistics vehicle is provided on the ground between the two guide rails. The pusher and the parking proximity switch are both connected to the controller. When the parking proximity switch is triggered, the controller controls the pusher to stop running.

[0017] After the logistics vehicle is towed between two guide rails by a tractor, it is pushed laterally by a pusher. When the logistics vehicle moves to the parking space, it triggers a parking proximity switch, and the controller controls the pusher to stop automatically, so that the logistics vehicle stops accurately in the parking space, making it easy for the robot arm to accurately grab the tire. After the robot arm completes the grabbing operation, the pusher pushes the logistics vehicle out of the track, and then the tractor can pull the logistics vehicle away. It is simple and convenient.

[0023] The core of this invention is to provide a tire transport vehicle positioning system that can achieve automatic positioning of tire transport vehicles with high positioning accuracy and efficiency.

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of a specific embodiment of the tire transport vehicle positioning system provided by the present invention; Figure 2 This is a schematic diagram of a specific embodiment of the cart pusher provided by the present invention.

[0026] The tire transport vehicle positioning system provided in this invention mainly includes a controller, a parking proximity switch 3, and two laterally extending guide rails 1. The area between the two guide rails 1 is a parking area for logistics vehicles. The parking proximity switch 3 corresponds to a parking space in the logistics vehicle parking area. The guide rails 1 restrict the logistics vehicle to only move forward or backward in one direction. A pusher 5 is installed on the ground between the two guide rails 1. Both the pusher 5 and the parking proximity switch 3 are connected to the controller. After the logistics vehicle is towed between the two guide rails 1 by a tractor, the pusher 5 can push the logistics vehicle to move laterally. When the logistics vehicle moves to the parking space, the logistics vehicle triggers the parking proximity switch 3, and the controller controls the pusher 5 to stop automatically, so that the logistics vehicle stops accurately in the parking space, which is convenient for the robot arm to accurately grab the tire. After the robot arm completes the grabbing operation, the pusher 5 pushes the logistics vehicle out of the track, and then the tractor can pull the logistics vehicle away. It is simple and convenient.

[0027] Based on the above specific implementation method, to facilitate operation, an entrance proximity switch 2, an exit proximity switch 4, and an indicator light 7 indicating the location of the logistics vehicle can be added. The entrance proximity switch 2 corresponds to the parking entrance of the logistics vehicle parking area, and the exit proximity switch 4 corresponds to the parking exit of the logistics vehicle parking area. The entrance proximity switch 2, the exit proximity switch 4, and the indicator light 7 are all connected to the controller. Specifically, the indicator light 7 can be controlled to display different colors to indicate the location of the logistics vehicle based on the triggering status of the proximity switches. For ease of installation, the entrance proximity switch 2, the parking proximity switch 3, and the exit proximity switch 4 are preferably all mounted on the guide rail 1, and can be arranged sequentially along the extension direction of the guide rail 1.

[0028] In the initial state, when there are no logistics vehicles in the parking area, indicator light 7 will be green and constantly lit, indicating that the logistics vehicle is allowed to enter. When transferring tires, the logistics vehicle is first pulled into the space between the two guide rails 1 by a tractor. When the logistics vehicle reaches the parking entrance, the entrance proximity switch 2 is triggered. At this time, indicator light 7 will be red and constantly lit, indicating that the tractor should stop. After the tractor is separated from the logistics vehicle and driven away from the parking area, the pusher 5 is started. The pusher 5 pushes the logistics vehicle laterally. When the logistics vehicle moves to the parking space, the parking proximity switch 3 is triggered, and the controller controls the pusher 5 to stop automatically. At this time, indicator light 7 will be yellow. The tires on the logistics vehicle can be transferred to the preset position by the robotic arm. After the tires are transferred, the pusher 5 is started again to push the logistics vehicle forward. When the logistics vehicle moves to the parking exit, the exit proximity switch 4 is triggered, and the controller controls the pusher 5 to stop pushing the logistics vehicle. At this time, indicator light 7 will be green and flashing. The operator can pull the logistics vehicle away. After the operator pulls the logistics vehicle off the track, indicator light 7 will turn green and return to constant light.

[0029] It is understandable that the width of the tractor is generally much smaller than that of the logistics vehicle. Therefore, when the tractor enters the logistics vehicle parking area, it will not trigger the proximity switches. The entrance proximity switch 2, parking proximity switch 3 and exit proximity switch 4 can only be triggered by the logistics vehicle.

[0030] Optionally, the entrance ends of both guide rails 1 are bent outward to form a funnel-shaped parking entrance, so that logistics vehicles can enter between the two guide rails 1.

[0031] Furthermore, limiting wheels 6 can be provided on the two guide rails 1. The axis of the limiting wheels 6 is preferably perpendicular to the ground. The limiting wheels 6 can further restrict the left and right deviation of the logistics vehicle, so that the logistics vehicle can only move forward or backward.

[0032] The tire transport vehicle positioning system provided by the present invention includes a pusher 5 that can push the logistics vehicle to move laterally along the track. The pusher 5 may specifically include a laterally extending drag chain 52, a sprocket that drives the drag chain 52 to rotate cyclically, and a motor 51 that drives the sprocket. A pushing part 53 is installed on the drag chain 52. When the logistics vehicle arrives at the parking entrance, the pushing part 53 can be connected to the logistics vehicle. When the motor 51 is started, it drives the drag chain 52 to rotate cyclically through the sprocket, so that the pushing part 53 moves from the parking entrance to the parking exit, thereby pushing the logistics vehicle from the parking entrance to the parking exit.

[0033] To ensure that the logistics vehicle can be accurately pushed to the parking space by the pusher 5, in one specific embodiment, the pusher 53 may include two push heads arranged at a distance from each other. Each push head includes a base plate and a vertical plate that are at an angle to each other. The bend of the push head is hinged to the cable chain 52, and the base plates of the two push heads abut against the cable chain 52. The vertical plates of the two push heads are arranged opposite to each other, so that the push head on the front side can only be rotated to the rear side around the hinge axis, and the push head on the rear side can only be rotated to the front side around the hinge axis.

[0034] For ease of description, the front and rear push heads of the push unit 53 can be referred to as the first push head 53-1 and the second push head 53-2, respectively. Meanwhile, to facilitate the connection between the push unit 53 and the logistics vehicle, a towing pin can be installed on the logistics vehicle.

[0035] When the motor 51 runs, it drives the cable chain 52 forward. When the first pusher 53-1 on the cable chain 52 touches the towing pin on the logistics vehicle, it flips over, causing the towing pin to be stuck between the first pusher 53-1 and the second pusher 53-2. Then, the motor 51 drives the cable chain 52 to move the logistics vehicle to the parking space. When it reaches the parking space, the motor 51 stops working. At this time, the first pusher 53-1 becomes a front limit device to prevent the logistics vehicle from continuing to move forward due to inertia, so that the logistics vehicle can be accurately stopped in the parking space. After all the tires on the logistics vehicle have been removed, the motor 51 drives the cable chain 52 to drag the logistics vehicle forward to the parking exit. The cable chain 52 sinks at the bend of the loop, so that the pusher 53 automatically separates from the towing pin of the logistics vehicle.

[0036] It should be noted that, in order not to affect the entry and exit of the logistics vehicle from the track, the pusher 53 should not be exposed above the ground when it is in the starting position and the ending position. Therefore, the cable chain 52 can adopt an underground loop design, and the starting position and the ending position of the pusher 53 can be set at the two ends of the cable chain 52 respectively.

[0037] In addition, the center of gravity of the first push head 53-1 and the second push head 53-2 are both on the base plate, so as to ensure that the first push head 53-1 can automatically reverse and return to the initial state after the first push head 53-1 flips under the action of the drag pin and the drag pin is locked in the first push head 53-1 and the second push head 53-2; preferably, the included angle between the base plate and the upright plate is 90°.

[0038] Of course, the specific structure of the pushing part 53 is not limited to this. In another specific embodiment, the pushing part 53 can be an electromagnet. After being energized, it can be attracted to the logistics vehicle, thereby realizing the connection between the pushing part 53 and the logistics vehicle. This allows the logistics vehicle to be accurately parked in the parking space. When the logistics vehicle is pushed to the parking exit, the electromagnet is de-energized, which can separate the logistics vehicle from the pushing part 53. This is simple and convenient, and is also within the protection scope of the present invention.

[0039] Based on the above specific implementation, in order to facilitate control and improve towing efficiency, it is preferable to install two pushers 53 on the drag chain 52. The length of the drag chain 52 and the position of the pushers 53 can be determined according to the design of the logistics vehicle, so that when one pusher 53 pushes the logistics vehicle off the track, that is, when the pusher 53 is in the end position, the other pusher 53 is waiting in the start position.

[0040] Furthermore, a cart proximity switch 54 can be provided for triggering by the pusher 53. The cart proximity switch 54 can be located at the front or rear end of the cable chain 52. When a pusher 53 pushes the logistics vehicle to the parking exit, the logistics vehicle triggers the exit proximity switch 4. At the same time, the cart proximity switch 54 can be triggered by one of the pushers 53. At this time, the indicator light 7 can be displayed as green and flashing, indicating that the operator can pull the logistics vehicle away. When the operator pulls the logistics vehicle out of the track, that is, when only the cart proximity switch 54 is triggered, the indicator light 7 displays as green and returns to a constant light, indicating that a new logistics vehicle is allowed to enter between the tracks.

[0041] In addition, when the trolley proximity switch 54 and the parking proximity switch 3 are triggered simultaneously, the indicator light 7 will turn yellow and flash, and an alarm will sound to indicate that the logistics vehicle has been towed too far and needs to be reversed.

[0042] Secondly, when any component malfunctions, indicator light 7 can turn red and flash, and simultaneously trigger an alarm to alert the operator.

[0043] It should be noted that the present invention does not impose specific limitations on the color and state displayed by the indicator light 7. As long as the different operating states can be distinguished, they are all within the protection scope of the present invention.

[0044] Please refer to Figure 3 , Figure 3 This is a schematic diagram of another specific embodiment of the tire transport vehicle positioning system provided by the present invention.

[0045] Based on the above specific implementation methods, in order to further improve the automation level of tire transfer, after the tractor pulls the logistics vehicle into the space between the two guide rails 1, when the tractor separates from the logistics vehicle and drives away from the logistics vehicle parking area, and the logistics vehicle has come to a stop, the controller can control the pusher 5 to start automatically, driving the logistics vehicle to move from the parking entrance to the parking space. Specifically, the laser rangefinder 8 can be used to detect whether the logistics vehicle has come to a stop, and the photoelectric switch assembly 9 can be used to detect whether there is a tractor in the logistics vehicle parking area.

[0046] The photoelectric switch assembly specifically includes multiple photoelectric switches 92 and a receiving board 93 for receiving signals from each photoelectric switch 92. The photoelectric switches 92 are arranged at horizontal intervals, with the interval between two adjacent photoelectric switches 92 being less than the length of the tractor vehicle. Each receiving board 93 corresponds to one photoelectric switch 92. The photoelectric switches 92 and receiving boards 93 are located on the left and right sides of the logistics vehicle parking area, respectively. Furthermore, to ensure that only the tractor vehicle can trigger the photoelectric switches 92, the height of each photoelectric switch 92 must be greater than the logistics vehicle but less than the tractor vehicle. Therefore, the photoelectric switches 92 and receiving boards 93 can be mounted on a bracket 91. For ease of installation, the bracket 91 can be fixed to the guide rail 1.

[0047] When the tractor pulls the logistics vehicle into the space between the two guide rails 1, the logistics vehicle triggers the entrance proximity switch 2. At the same time, the signal of the photoelectric switch 92 is blocked by the tractor. After the tractor separates from the logistics vehicle and drives away from the logistics vehicle parking area, the tractor no longer blocks the signal of the photoelectric switch 92. When the measurement value of the laser rangefinder 8 is stable, it means that the logistics vehicle has come to a stop. At this time, the controller can control the pusher 5 to start automatically and drive the logistics vehicle from the parking entrance to the parking space.

[0048] Based on the above specific implementation methods, in order to further improve the automation level of tire transfer, it is preferable to connect the controller to the tire transfer robot. When the logistics vehicle moves to the parking space and triggers the parking proximity switch 3, the robot automatically starts and transfers the tires on the logistics vehicle to the preset position. After the robot completes the gripping operation, the controller controls the pusher 5 to start automatically and drive the logistics vehicle from the parking space to the parking exit.

[0049] Furthermore, the controller preferably stores tire demand information and the position information of the tires on each logistics vehicle. The tire transport vehicle positioning system provided by the present invention may also include a barcode scanner 10 for scanning the vehicle code on the logistics vehicle. Specifically, the barcode scanner 10 may be set on the guide rail 1 near the parking proximity switch 3. When the parking proximity switch 3 is triggered by the logistics vehicle, the pusher 5 stops, the barcode scanner 10 starts, and the barcode scanner 10 scans the vehicle code on the logistics vehicle to obtain the position information of each tire on the logistics vehicle. Then, the controller controls the robotic arm to automatically grab the tires according to the tire demand information and position information.

[0050] In one specific embodiment, the present invention provides a tire transport vehicle positioning system, the specific operation of which can be performed according to the following steps:

[0051] S1: Indicator 7 is green and constantly lit;

[0052] S2: The tractor pulls the logistics vehicle into the space between guide rails 1. The logistics vehicle triggers the entrance proximity switch 2, and the indicator light 7 turns red and stays on. The tractor stops.

[0053] S3: The tractor unit uncouples and drives away from guide rail 1;

[0054] S4: When the measurement value of the laser rangefinder 8 is stable and the photoelectric switch assembly 9 does not detect the tractor, start the trolley pusher 5 to push the logistics vehicle forward;

[0055] S5: The logistics vehicle triggers the parking proximity switch 3, the pusher 5 stops, and the barcode scanner 10 starts scanning the vehicle code on the logistics vehicle.

[0056] S6: When the barcode scanner 10 successfully scans the code and the measurement value of the laser rangefinder 8 is stable, start the robotic arm to automatically grab the tire on the logistics vehicle and turn off the barcode scanner 10 at the same time.

[0057] S7: After the robotic arm completes the grasping operation, start the trolley pusher 5;

[0058] S8: The logistics vehicle triggers the exit proximity switch 4, the indicator light 7 turns green and flashes, and at the same time, one of the pushing parts 53 of the cart pusher 5 moves to the starting position, triggering the cart proximity switch 54, causing the cart pusher 5 to stop running;

[0059] S9: The logistics vehicle is manually towed away by a tractor, and indicator light 7 is green and constantly lit.

[0060] In summary, the tire transport vehicle positioning system provided by this invention, utilizing the parking proximity switch 3 and the pusher 5, can achieve automatic positioning of the tire transport vehicle with high positioning accuracy and efficiency, saving time and effort.
