Example 1

As shown in fig. 1 to 3, a steel plate transferring system comprises a first carrying device for unloading steel plate materials, an RGV device 1 for receiving and transferring the steel plate on the first carrying device, and a second carrying device for receiving and transferring the steel plate on the RGV device 1 to a storage bin; the system also comprises a storage device for storing the steel plate incoming material information, wherein the storage device is arranged on the RGV equipment 1 and is in communication connection with the EMS system.

After the steel plate incoming materials enter the production area, the steel plate incoming materials are grabbed by the first conveying device block by block and transferred to the RGV equipment, and after the RGV equipment 1 receives the steel plate transferred by the first conveying device, the storage device on the RGV equipment 1 correspondingly stores the steel plate incoming material information and transmits the steel plate incoming material information to the EMS system. The steel plate information can be stored in the EMS system by manual input or by scanning two-dimensional code information on the steel plate. RGV equipment 1 corresponds to transport the steel sheet of same model and is the same feed bin position in warehouse according to steel sheet model information, and at this moment, second handling device will accept the steel sheet on the RGV equipment 1, and transport the steel sheet after snatching in the corresponding feed bin, the stack is stored. Each bin is provided with a corresponding number, so that the stored number of the steel plates and the model information of the steel plates in each bin can be inquired in an EMS system. When the RGV device 1 transfers the steel plates, one piece can be transferred at a time or a plurality of pieces can be transferred at a time. Through first handling device, RGV equipment 1 and second handling device, realized transporting the automation of steel sheet, replaced artifical transport operation, improved the transportation efficiency of steel sheet greatly, also avoided the potential safety hazard in the manual operation process simultaneously. And the stored information of each steel plate can be stored in an EMS system, so that the information storage of steel plate materials is realized, and the material taking in the subsequent working procedure is convenient.

The AGV apparatus 1 is an existing mature product, and the AGV apparatus 1 is also called an unmanned carrier or a carrier robot. Refers to an automatic guiding device equipped with electromagnetic or optical or radar for laser light. The AGV can travel along a path along which guidance is developed by a user, and thus has an information security protection function. The main features of an AGV include vehicle programming, safety protection systems, parking selection devices, and load transfer for various functions. The AGV can autonomously travel along a guide path planned by a user and move to a specified position with the help of the computer. The system information technology of AGV and the development of products can become important basic equipment and technology of flexible production, flexible assembly and warehouse logistics automation modes at present. The guidance of the AGV is moved based on the position of the AGV's carriage as derived by the guidance system sensors. The target value is provided according to the path of the AGV field and the actual cost control management of the AGV trolley is calculated. In short, the guiding control of the AGV is the track tracking of the AGV trolley. There are many modes of AGV guidance, such as being able to utilize the center point of the problematic guidance system sensor as a reference point. The control management target of the AGV can also correct the rotation speed of the driving wheel by detecting the relative important positions of the reference point and the virtual point so as to change the moving direction of the AGV, and the reference point is positioned above the virtual point of the network as much as possible. Thus, the development of the AGV can always track the guide wire to run. When the device receives a user instruction, the stored map, the current position of the AGV and the traveling direction can be obtained through planning and analysis in the calculation of the system controller, and a more suitable and rapid traveling route is selected. The drive can control the AGV trolley, and when the AGV reaches an accurate position, the transferable mechanism acts to complete the independent loading process. And then the AGV trolley can start and drive to another target point to carry out unloading work, and after the AGV trolley is accurately stopped, the AGV trolley completes actions through the transfer mechanism to complete normal and complete unloading work, and reports the position and the state of the AGV trolley to the control management system in real time. The AGV may then start and drive to the standby area for the next task.

Example 2

The system comprises a first carrying device for unloading steel plate supplied materials, RGV equipment 1 for receiving the steel plates on the first carrying device and carrying out transfer, and a second carrying device for receiving the steel plates on the RGV equipment 1 and transferring the steel plates to a storage bin; the system also comprises a storage device for storing the steel plate incoming material information, wherein the storage device is arranged on the RGV equipment 1 and is in communication connection with the EMS system.

The difference between this embodiment and embodiment 1 is that: the storage device may be an RFID encoder. In the steel plate transferring process, steel plate information can be input to the RFID encoder in a manual mode, and the steel plate information can be automatically stored through the RFID encoder.

And the second carrying device is provided with an RFID decoder for identifying the steel plate information in the RFUD encoder, and the RFID decoder is in communication connection with the EMS system. The RFID decoder on the second conveyance device recognizes the information in the RFID encoder by scanning or the like, and transmits the information to the EMS system. Therefore, what type of steel plate is placed in each bin can be stored in the EMS and used for inquiry.

Example 3

The difference between this embodiment and embodiment 1 is that: the crown block 2 may be used as the first carrying device and the second carrying device. The crown block 2 includes a carriage movable in the X-axis direction and a carriage movable in the Y-axis direction, and a suction cup movable in the Z-axis direction is movably provided on the carriage. The steel plate is sucked and grabbed through the sucking disc.

Considering that the steel plate is a block-shaped object, and the weight is generally large. In order to facilitate grabbing of the steel plate, the steel plate cannot fall off from the sucker in the transferring process, and the sucker can preferentially adopt the electromagnetic sucker. The electromagnetic chuck is a machine tool accessory product produced by the principle that an internal coil is electrified to generate magnetic force, a workpiece contacted with the surface of the panel is tightly sucked through a magnetic conduction panel, the coil is powered off, the magnetic force disappears to realize demagnetization, and the workpiece is taken down. The overhead travelling crane is used as universal equipment in the industry, and in the embodiment, the overhead travelling crane is only used for sucking and transporting materials, so that the overhead travelling crane can be suitable for the embodiment as long as the overhead travelling crane can adsorb, grab and transport the materials.

Example 4

The present embodiment differs from embodiment 3 in that a three-dimensional laser scanner is provided on the cart. The scanner establishes a space coordinate system in a reservoir area, performs three-dimensional model mapping on fixed points of each RGV device, and finally generates the geometric dimension, initial position and target position of the steel plate to be transported. The coordinate data are used for positioning control by the crown block, the crown block respectively performs speed control by means of real-time position feedback of the laser of the large vehicle, the laser of the small vehicle and the lifting encoder, and finally the accurate positioning of the target position is completed.

The space model established by the three-dimensional laser scanner is the overall model of the stacked steel plates carried by RGV equipment, but when the steel plate conveyor executes transfer operation, the steel plates need to be lifted and transported for a plurality of times, so that the accurate position of the single steel plate needs to be known. Therefore, when the crown block is positioned above the steel plate to be carried, the diffuse reflection laser installed on the sucker lifting appliance can be utilized for carrying out steel plate centering check, and the principle is as follows: the diffuse reflection laser has twice mutation in sensing value from the ground to the edge of the steel plate and from the steel plate to the edge of the shifted steel plate, and the hanger can measure the center position of the steel plate and the width of the steel plate. Therefore, the crown block can be more accurately adjusted to the upper part of the geometric center of the steel plate, and the suckers which are transversely and symmetrically arranged can be transversely adjusted according to the width information so as to adapt to the lifting actions of the steel plates with different width specifications, so that the lifting process is more stable and reliable.

In this embodiment, a weighing sensor for confirming the adsorption weight of the suction cup is provided on the cart. The weight of the steel plate adsorbed on the sucker is confirmed through the weighing sensor, so that whether the steel plate is really adsorbed on the sucker is confirmed. Meanwhile, in the lifting process, in case of the phenomenon that the stored steel plate falls, the weighing sensor can sense at the first time, so that the crown block temporarily or sends out an alarm signal.

In order to further improve the adsorption precision of the sucker, a laser positioning device can be arranged on the trolley, and the specific position of the crown block can be confirmed through the laser positioning device.
