All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the application of the invention for compatible long and short sledge rolling machine conveying control mainly comprises a detection module (a proximity sensor and a photoelectric correlation detection sensor), a control module (a PLC control system and a frequency converter), and an action module (a clamping mechanism, a splitting and combining sledge mechanism, cylinder action, motor operation, and rolling machine operation).
The system layout shown in FIG. 2 comprises 1 set of 6 proximity sensors, 2 sets of photoelectric sensors, 2 sets of sensors, 3 cylinders at 3 positions, 1 set of 4 pneumatic clamps, 1 set of 5 separating/closing sledge mechanisms, 2 sets of 6 decelerating electrodes, 2 sets of 7 MOVIIT field frequency converters and 1 set of 8 PLC control systems.
As shown in fig. 3, the splitting and combining sleds are schematic diagrams, the splitting sleds are 2 long sleds which are combined together and carry light truck heads, the 2 long sleds are split into 2 short sleds, and after the splitting, the 2 short sleds carry 1 light truck and independently travel. And the closing sledge is the reverse, namely 2 independent short sledges are combined into a long sledge at the sledge closing station, and then 2 light trucks travel together. It is specifically stated here that, because of the differences in vehicle types, there are universal intermediate pallets designed between the truck heads and the skids, one for each head, while the SUV vehicle types are directly connected to the skids. The vehicle can be combined with any 2 short sleds with the length of 2.7 meters into a long sledge with the length of 5.4 meters, and is just compatible with SUV-carrying vehicle models.
As shown in a flow chart of a sledge dividing system in fig. 4, firstly, the sledge entering a station before the sledge dividing system is determined to be a long sledge, namely, 6 proximity sensors on a rolling machine sense all the sledge, the in-place information of the long sledge is transmitted to a PLC system, then, whether the sledge is uploaded by a lower long sledge is an SUV or a light truck is judged, namely, a front and a back pair of photoelectric correlation switches 2 are used for detecting, if the correlation switches are not shielded, the PLC system receives the information and judges that the information is the SUV without dividing the sledge, and then, the PLC system sends an instruction to 2 frequency converters and controls 2 motors of the rolling machine to synchronously transmit the SUV to the next rolling machine station; on the contrary, the photoelectric correlation switch is shielded by the tray, the PLC system receives information and judges that the information is a light card, the PLC system further controls the cylinder to act, namely the positioner clamps, after the action is finished, the PLC sends an instruction to the cylinder to control the operation of the splitting sledge mechanism, after the splitting sledge mechanism finishes, the cylinder is controlled again to loosen the positioner, then the PLC controls the frequency converter 2 at the front end of the rolling machine independently to drive the motor 2, the split front vehicle is conveyed to the next rolling machine (the premise is that the next rolling machine is vacant), after the front vehicle leaves the rolling machine, namely, the front 3 proximity sensors (occupation 2, deceleration 2 and in-place 2) are not occupied, the PLC controls the frequency converter 1 at the rear end of the rolling machine independently to drive the motor 1, the rear vehicle is conveyed to the front end of the rolling machine, the rear three proximity sensors (occupation 1, deceleration 1 and in-place 1) are separated, the front three proximity sensors (occupation 2, deceleration 2 and in-place 2) are simultaneously sensed, and finally the front end of the rolling machine is controlled to operate independently, and (4) sending the rear vehicle out of the sub-skid rolling machine, wherein all the 6 sensors (occupying 1, decelerating 1, in-place 1, occupying 2, decelerating 2 and in-place 2) are not sensed.
FIG. 5 is a flow chart of a sled closing system, wherein firstly, a sled body is in place, the PLC judges whether the sled is an SUV or a light truck type according to the sensing condition of 6 proximity sensors on a rolling machine, if the 6 proximity sensors sense all the sensors, the sled passes through the sensors, the vehicle type is an SUV, and the sled closing is not needed, so that the PLC sends an instruction to 2 frequency converters to simultaneously control 2 motors of the rolling machine to synchronously convey the SUV to the next rolling machine station; if the sledge body is in place, only the first three proximity sensors (occupying 2, decelerating 2 and in place 2) sense the sledge body, the PLC judges that the single sledge is in place, the vehicle type is light truck, and the rolling machine stops to run at the moment to wait for the next single sledge to arrive. When the next short sledge-loaded light card enters the rear end of the rolling machine, the PLC judges that 2 light cards reach the sledge closing station by interlocking with the previous station, so that the light cards and the SUV vehicle types can be judged at the station without designing a photoelectric correlation switch. And then the PLC controls the cylinder to act, namely the positioner clamps, after the action is finished, the PLC sends an instruction to the cylinder to control the closing sledge mechanism to act, after the sledge is closed, the PLC controls the cylinder again to release the positioner, and then the PLC simultaneously controls 2 frequency converters of the rolling machine to drive 2 motors to synchronously convey to the next rolling machine station.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
