Fig. 2 is a flowchart of a tire breaking method according to an embodiment of the present invention, wherein the method according to the embodiment shown in fig. 2 can be implemented based on the method according to the embodiment shown in fig. 1.
Referring to fig. 2, a tire crushing method according to an embodiment of the present invention includes:
step 201: profile data of the tire is acquired.
The profile data of the tire is used to describe three-dimensional profile information of the tire. Specifically, the contour data is tread contour data, or the contour data is sidewall contour data, or the contour data is tread contour data and sidewall contour data. The tread profile data is used for describing a three-dimensional structure of the tread, the sidewall profile data is used for describing a three-dimensional structure of the sidewall, the tread is a tire driving surface of the tire, which is in contact with the ground, and the sidewall is a part of a side portion of the tire.
Optionally, in an embodiment of the invention, the tire is a junked tire. I.e. the tire is a used and discarded tire. By using the method provided by the embodiment of the invention, the tires can be efficiently crushed, so that the waste tires can be recycled.
For example, the control system acquires contour data of a tire from a three-dimensional (3D) camera. As shown in fig. 3, the 3D camera may scan the tire to obtain profile data of the tire. The 3D camera then sends the profile data of the tire to the control system.
Step 202: and according to the profile data, rotating the tire and moving a water jet of the crushing device in real time so as to enable the water jet to be positioned at the target working position.
The target working position is the position where the water jet cutter reaches the preset crushing angle and the preset crushing distance. The preset crushing angle is a preset included angle between a water flow sprayed by the water jet and a plane where a crushing position of the tire is located, and the preset crushing distance is a preset distance between a water jet of the water jet and the crushing position.
The tire is located broken station, and broken station includes crushing equipment, and crushing equipment includes the water sword. The water jet can jet water flow through the water jet, and the water jet is used for crushing the tire through the water jet.
In order to facilitate the water jet to break the tire, the water jet needs to be moved to a proper spatial position, namely, to a target working position, and the water jet at the target working position can effectively break the tire. The target working position is a space position of the water jet cutter relative to the tire, and in order to enable the water jet cutter to be located at the target working position, the water jet cutter can be achieved by rotating the tire and moving the crushing equipment.
When the water jet cutter is positioned at the target working position, the water jet cutter reaches the position of the preset crushing angle and the preset crushing distance. The preset crushing angle is a preset included angle between a water flow sprayed by the water jet and a plane where the crushing position of the tire is located. The tire breaking position is a position on the tire which is impacted by the water flow of the water jet cutter so as to be broken. The broken position of tire is located certain plane, and this plane forms the contained angle with the water current of the straight line injection of water sword, and when this contained angle was for predetermineeing broken angle, the crushing effect of water sword was better. The preset crushing distance is a preset distance between a water spraying opening of the water jet cutter and a crushing position. The water flow is sprayed out from the water spraying opening of the water jet, and the distance between the water spraying opening of the water jet and the crushing position of the tire influences the impact force of the water flow on the tire, so that the crushing effect of the water jet is influenced. When the water jet cutter is positioned at the preset crushing distance, the crushing effect of the water jet cutter is better.
In the embodiment of the invention, the preset crushing angle and the preset crushing distance can be obtained through experimental tests. The specific values of the preset crushing angle and the preset crushing distance can be various, for example, the preset crushing angle is 85-90 degrees, and the preset crushing distance is 2-10 mm.
Optionally, the step of rotating the tire and moving the water jet of the crushing device in real time according to the profile data specifically comprises: and determining the target rotation angle of the tire and the target moving position of a water jet of the crushing equipment according to the profile data, the preset crushing angle and the preset crushing distance. Then, the tire is rotated to a target rotation angle, and the water jet is moved to a target moving position. The preset crushing angle and the preset crushing distance are predetermined data, and after the control system acquires the contour data, the angle of the tire required to rotate and the position of the water jet cutter required to move can be calculated according to the contour data, the preset crushing angle and the preset crushing distance. And then, according to the calculation result, rotating the tire to a target rotation angle, and moving the water jet to a target moving position so as to enable the water jet to be positioned at a target working position.
Wherein, the mode of rotating the tire has the multiple, for example place the tire on a platform, and the platform rotates, can drive the tire rotation. Alternatively, the tire periphery is gripped using a gripper, by which the tire is rotated.
In a specific example, the step of rotating the tyre and moving the water jet of the crushing device in real time according to the profile data specifically comprises: rotating the tire by the fixture according to the profile data, and moving a water jet of the crushing apparatus in real time. Wherein the clamp is used to support the inner ring of the tire, as shown in figure 4. Particularly, the outer side face of the clamp comprises a telescopic block, the clamp extends into the inner ring of the tire, and then the telescopic block of the clamp extends out of the outer side face of the clamp, so that the tire can be clamped. When the clamp rotates, the tire can be driven to rotate.
It should be appreciated that step 202 is one of the specific implementations of the step of moving the water jet of the crushing plant to the target work position based on the contour data.
Step 203: and controlling a water jet cutter positioned at the target working position to jet water flow to the crushing position so as to crush the tire.
When the water jet is located at the target working position, the position relation between the water jet and the tire crushing position is beneficial to efficient tire crushing, so that the water jet located at the target working position can be controlled to jet water flow to the crushing position, and the tires can be crushed through the impact of the water flow on the tires.
In an embodiment of the invention, the water jet injected by the water jet may be an ultra-high pressure water jet.
The tire can be made of rubber, and rubber powder is obtained after the tire is crushed by water flow of a water jet cutter. By recycling these rubber powders, recycling of the tire can be achieved.
In some embodiments of the present invention, the breaking position on the tire may be changed by rotating the tire while the water stream of the water jet sprays the tire, to accomplish breaking of the tire as a whole.
It should be appreciated that when the profile data is tread profile data, step 203 may control the water jet blade located at the target working position to jet a water stream to the breaking position to break the tread of the tire. When the contour data is sidewall contour data, step 203 may control a water jet blade located at the target working position to jet water flow to the crushing position to crush the sidewall of the tire. When the profile data is tread profile data and sidewall profile data, step 203 may control a water jet at the target working position to jet water to the breaking position to break the tread and sidewall of the tire. To achieve breaking of the tread and/or sidewall integrity, the tire may be rotated and/or a water knife moved to adjust the breaking location of the tire.
In other embodiments of the present invention, the step of acquiring the profile data of the tyre specifically comprises: the tire is moved to a 3D scanning station, wherein the 3D scanning station includes a 3D camera. Then, the rotating tire is scanned by a 3D camera to obtain profile data of the tire. And sending the contour data to the control system by the 3D camera. The 3D camera may be a high speed 3D camera with which 3D images of the tyre profile may be acquired before the tyre is broken. Accordingly, the tire breaking method according to the embodiment of the present invention further includes: the tire is moved from the 3D scanning station into a crushing apparatus. Thus, the tire can be detected as the profile data, and then the tire can be broken.
At this time, the control of the crushing operation of the tire may be achieved using a control system. Specifically, the step of moving the water jet of the crushing device to the target working position according to the profile data specifically includes: and controlling a water jet of the crushing equipment to a target working position through a control system according to the profile data.
And controlling the water jet cutter positioned at the target working position to jet water flow to the crushing position, and specifically comprising the following steps of: and controlling the water jet cutter positioned at the target working position to jet water flow to the crushing position through a control system.
In other words, the control system is electrically connected with the water jet so that the control system can control the moving position and the working state of the water jet.
For example, profile data obtained by measuring the tire is matched with the water jet position to complete the breaking of the tire. After the control system acquires the contour data, the control system can convert a coordinate system of the contour data to acquire industrial control data and determine the rotation position of the tire and the movement position of the water jet. The specific control process may be that the clamp is connected to a rotating shaft of a servo motor, the servo motor is electrically connected to a Programmable Logic Controller (PLC), and the control system controls the rotation of the rotating shaft of the servo motor through the PLC, for example, controls the rotating speed and the rotation direction, so as to control the rotation of the clamp through the servo motor, thereby controlling the rotation of the tire clamped by the clamp. The water jet scalpel is connected with another servo motor, the servo motor is electrically connected with the PLC, the control system controls the rotation of a rotating shaft of the servo motor through the PLC, and then the spatial position of the water jet scalpel is adjusted through the transmission of gears or transmission belts and the like. The industrial personal computer and the PLC of the Control system may communicate through an ethernet Transmission Control Protocol (TCP)/Internet Protocol (IP) interface, so that the movement of the actuator is more accurate.
In order to more intuitively understand the tire crushing method according to the embodiment of the present invention, the tire crushing method according to the embodiment of the present invention is described in detail below with a specific use scenario, in which the tire is a waste tire as an example.
As shown in fig. 3, the scrap tire 301 is moved by the conveyor to the 3D scanning station, at which time the gripper 302 grips the inner ring of the scrap tire 301. The 3D camera 303 starts scanning the tread of the used tire 301 to obtain tread profile data. At the same time, the gripper 302 moves the junked tire 301 so that the junked tire 301 rotates one turn, and thus, the 3D camera 303 collects the complete tread profile data. The 3D camera 303 may send the tread profile data to a control system. Then, the clamp 302 enters the cracking station with the waste tire 301, the waste tire 301 is moved into the crushing device from the 3D scanning station, and the control system determines a target rotation angle of the waste tire 301 and a target moving position of the water jet 401 of the crushing device according to the received tread profile data, the preset crushing angle and the preset crushing distance so as to rotate the waste tire 301 to the target rotation angle and move the water jet 401 to the target moving position, so that the water jet 401 is located at the target working position. The present example may regulate the position of the water jet 401 in real time. Then, as shown in fig. 4, the water jet blade 401 located at the target working position is controlled to jet a water current to the crushing position of the junked tire 301 to crush the tire. Wherein, the water flow sprayed by the water jet 401 is ultrahigh pressure water jet. In the crushing process, the clamp 302 drives the waste tire 301 to rotate until the tread of the waste tire 301 is crushed, so that the best cracking effect is obtained, and the crushing efficiency is improved. Thus, according to the tire crushing method provided by the embodiment of the invention, the angle and the distance of the water jet can be accurately adjusted at any time according to the surface profile of the waste tire 301, and even if the surface wear degrees of the waste tire 301 are inconsistent, the water jet 401 can keep the most reasonable posture relative to the tire tread, so that the high-efficiency crushing of the tire is realized.
In summary, in the tire crushing method according to the embodiment of the present invention, after the contour data of the tire is acquired, the water jet of the crushing device is moved to the target working position according to the contour data. The target working position is a position where the water jet cutter reaches a preset crushing angle and a preset crushing distance, the preset crushing angle is a preset included angle between a water flow jetted by the water jet cutter and a plane where the crushing position of the tire is located, and the preset crushing distance is a preset distance between a water jet of the water jet cutter and the crushing position.
