When the forward inching button is pressed down, the motor is driven to rotate forward, so that the conveyor belt is driven to operate in the forward direction, and after the conveyor belt is loosened, the motor stops and the conveyor belt stops operating. When the reverse inching button is pressed down, the driving motor rotates reversely to drive the conveying belt to run reversely, and after the conveying belt is loosened, the motor stops and the conveying belt stops running.

In addition, if the forward jog button and the reverse jog button are pressed at the same time, an interlock is formed and the conveyor belt does not operate.
Step two: automatic sorting mode for automatic sorting system
The system can finish the automatic sorting work of the waste materials in the blanking workshop in an automatic mode, firstly, the waste materials from the blanking workshop need to be placed into a material device, and the material device can sequentially supply the materials to a transmission device; then the material moves forwards along with the transmission device, the sensing detection device judges the material type of the material in the operation process and transmits a detection signal to the control device; then, the control system can control the corresponding execution device to sort according to the signal, and meanwhile, the control device can adjust the material device and the transmission device according to the actual operation condition of the sorting system; and finally, the executing device pushes the materials into the material storage area corresponding to the materials according to the signals of the control device. And after the material sorting work is finished, resetting the system to prepare a good operation environment for restarting the next system work. The operation flow of the automatic sorting mode is shown in fig. 4, which briefly describes the basic steps of the automatic sorting system in the automatic operation mode as follows:
step 2-1: the mode of operation is first selected, similar to the manual mode. Taking fig. 4 as an example, the local operation mode is selected, the automatic control mode is selected, the mode confirmation button is pressed, then the system enters the local automatic mode, and the local indicator light and the automatic indicator light are always on;
step 2-2: and when the starting button is pressed down, the production line enters a running state, and the corresponding indicator light is on. Resetting the quantity of all material grooves, namely pressing a reset button, wherein the quantity of all material grooves is 0, and the whole production line enters a running state and waits for the materials to enter so as to realize a sorting task;
step 2-3: if the material detection switch detects that the material is in the material groove, the motor starts to rotate forwards, the conveyor belt runs forwards, and otherwise, the conveyor belt does not run and the system is still in a standby state;
step 2-4: when the conveyor belt runs in the forward direction and materials pass through the first position proximity switch, adding 1 to the total number of the materials so as to count the total number of the materials;
step 2-5: the material continuously moves forwards along with the conveyor belt and passes through the iron detection sensor, if the iron detection sensor detects that the material is iron, the No. 1 material pushing cylinder pushes out, the No. 1 material groove counts and adds 1, otherwise, the material continuously moves forwards;
step 2-6: the material continuously moves forwards along with the conveyor belt and passes through the aluminum detection sensor, if the aluminum detection sensor detects that the material is aluminum, the No. 2 pushing cylinder pushes out, the No. 2 material groove counts and adds 1, otherwise, the material continuously moves forwards;
step 2-7: the steps are carried out in sequence, and the sorting is not finished until the materials enter the material grooves corresponding to the materials.
Further, in two working modes, when equipment has a fault, a corresponding alarm lamp 1 or 2 on the operation panel can flash as an alarm signal, and different faults can have different flashing frequencies; after a fault has occurred, the operator is required to respond to the fault in the host computer to indicate that the fault has been noticed and resolved, and the corresponding warning light is turned off only after the fault has been resolved. If the fault is still not eliminated, the alarm lamp is kept in a normally-on state until the fault is eliminated. Therefore, the system can respond to faults and emergency situations in the system, and timely early warning and reminding of the system faults are realized.
Further, as shown in fig. 1 and 5, in the touch screen HMI control mode, the human-computer interaction interface initial interface sets main function interfaces such as manual operation, automatic operation, parameter setting, fault alarm, user management, and the like. Under the automatic operation interface, the production line can be monitored through the operation state monitoring interface, so that whether the sorting normally works can be identified, and the overall monitoring and control of the automatic material sorting process can be realized; under the operation state monitoring interface, because the materials in the No. 7 material groove are not identified by various preset material monitoring sensors, the materials have two types, one is waste products caused by detection errors of the sensors, the other is non-preset sorting type materials, the materials are collectively called sorting waste products, the sorting result of the automatic sorting system can be simply evaluated according to the proportion (sorting rejection rate) of the number of the materials in the No. 7 material groove to the total number of the materials, when the sorting rejection rate is 0-2%, the sorting waste product is excellent, when the sorting rejection rate is 3-10%, the sorting waste product is qualified when the sorting rejection rate is 11-20%, and the sorting waste product is unqualified when the sorting rejection rate is 21-100%.

The manual commissioning mode of fig. 5 shows the cylinder in an extended state and the motor running in forward direction.
The main interface of the touch screen HMI can also directly enter an automatic operation interface, and the automatic operation interface comprises a control interface and a state monitoring interface in an automatic sorting mode. The basic functions of the automatic sorting system are mainly formed by buttons, knobs, indicator lights and I/O domains in a control interface, wherein the buttons in a blue dotted line frame simulate sensor signal input during system simulation; meanwhile, the interface can enter a fault alarm interface to confirm the generated fault information. And the running state can be monitored in the running state monitoring interface, the sorting quantity in each trough can be indicated, and the whole automatic sorting system can be simply evaluated. In addition, once a fault is found or an unreasonable situation occurs in operation, all operations can be forcibly stopped by using an emergency stop button to ensure the safety of the system.
In fig. 5, in the initialization step of automatic operation in the automatic sorting mode, the system is already in operation, but since the material detection sensor detects that there is no waste left in the initial trough from the blanking workshop, the conveyor belt does not operate, and at this time, the trough does not count even if the subsequent iron sensor or the like detects the material.
In the normal operating mode of automatic operation, the system is in the automatic sorting state, and material detection sensor detects that there is the waste material that comes from the unloading workshop in the silo, and the conveyer belt operation this moment, subsequent automatic sorting part also begin to operate, and the silo begins the count.
In the fault alarm step, the system is under the control mode of remote automatic operation at this moment, so for the convenience of demonstration, the upper limit of total material is set to 5, namely when the total material reaches 5, the system can produce the fault alarm, alarm lamp 1 glimmers, pop up the overall alarm interface and reveal the reason that the alarm produced at the same time. At the moment, the fault can be eliminated step by step according to the prompted fault reason, and after the fault is eliminated and the fault response button is pressed, the fault can be responded and confirmed on the fault alarm interface.
In the scram step, a fault occurs in the system and an alarm is generated. For safety reasons, pressing the emergency stop button may be selected to prevent accidents. After the emergency stop button is pressed, only the emergency stop indicator lamp is on, and other output peripherals are all set to be zero. Without the emergency stop button, the system will not function here even if the start button is pressed. At this time, the user should return to the main interface, and after logging in, the user can enter the parameter modification interface according to the account authority to modify the preset upper limit of the material.
In the parameter setting step, a user with engineer authority should be logged in before entering the parameter setting, a keyboard is automatically called when the upper limit of the preset material is modified, and the range of the parameter is marked on the upper and lower sides of an input box, for example, the upper limit max =32767 of the preset material, the lower limit min =1 of the preset material, the parameter is successfully modified after the entry is completed, and the upper limit of the preset material is set to 531 in the figure.
In the step of monitoring the automatic sorting state, the running state detection interface mainly comprises a corresponding configuration of the automatic sorting system, related buttons and indicator lamps, wherein the buttons in the blue dotted line frame simulate the signal input of a sensor during the simulation of the system. After the parameter modification of the previous step, the upper limit of the material is changed to 531, and the total number of the material in the figure is 56 and no alarm is generated, thereby verifying that the parameter is successfully modified. The entire sorting system is in a state of automatically sorting materials, and the sorting processes of each material are independent of each other.
The flow and the main functions of the automatic sorting control of the specific case in the embodiment of the present application have been completed. Meanwhile, the above description of the specific embodiments is intended to describe and illustrate the technical solutions of the present invention, and the above specific embodiments are only illustrative and not restrictive.
