Therefore, a series of issues such as how to better combine manual packaging with unmanned operations, ensure personnel safety, and improve production efficiency urgently need to be resolved. Utility Model Content

[0003] The purpose of the utility model is to provide an interlocking control device for use in a manual packaging area, which effectively solves the problem that the packaging area personnel's working process cannot interact with the overhead crane, and uses an interlocking mutual protection mechanism to ensure the safety of the packaging personnel, provides support for the unmanned realization of the warehouse area, and solves the above-mentioned problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] An interlocking control device for use in a manual packaging area comprises a limit switch, a packaging area fence, a connecting fall chain, a programmable controller, an integrated control box, a push button switch, a signal light, an Ethernet network, an industrial control system server and a management operation computer; there are multiple packaging areas, and packaging area fences are fixed around each packaging area, an open channel is provided on the packaging area fence, and a limit switch is provided on the packaging area fence on one side of the open channel, the limit switch matches one end of the connecting fall chain, and the other end of the connecting fall chain is connected to the packaging area fence on the other side of the open channel; the integrated control box is installed on a column in a warehouse area, the number of integrated control boxes is the same as the number of packaging areas, and one integrated control box matches one packaging area; push button switches, signal lights and a programmable controller are installed in the integrated control box, and the integrated control box is connected to the industrial control system server and the management operation computer via an Ethernet network.

[0006] Furthermore, the programmable controller on each integrated control box is connected to the corresponding limit switch, and the programmable controller is connected to the industrial control system server via an Ethernet network.

[0007] Furthermore, there are three button switches on the integrated control box, namely, a reel hoisting permission button, a reel unwinding permission button and an emergency stop button, and the reel hoisting permission button, the reel unwinding permission button and the emergency stop button are respectively connected to the programmable controller.

[0008] Furthermore, the industrial control system server is located in the electrical room of the unmanned overhead crane, and the management operation computer M2 is located in the operation room of the warehouse area.

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] An interlocking control device for use in a manual packaging area comprises a limit switch, a packaging area fence, a connecting fall chain, a programmable controller, an integrated control box, a push button switch, a signal light, an Ethernet network, an industrial control system server and a management operation computer; there are multiple packaging areas, each of which is fixed with a packaging area fence on all sides, an open channel is provided on the packaging area fence, a limit switch is provided on the packaging area fence on one side of the open channel, the limit switch matches one end of the connecting fall chain, and the other end of the connecting fall chain is connected to the packaging area fence on the other side of the open channel; the connecting fall chain is used to enclose the entrance channel of the packaging area, and at the same time cooperates with the limit switch to serve as a "safety door" for packaging personnel to prevent packaging personnel from entering by mistake.

[0018] The integrated control box is installed on the column of the warehouse area. The number of integrated control boxes is the same as the number of packaging areas, and one integrated control box matches one packaging area. The integrated control box is installed with a button switch, a signal light and a programmable controller. The integrated control box is connected to the industrial control system server and the management operation computer via an Ethernet network.

[0019] The programmable controller on each integrated control box is connected to the corresponding limit switch, and the programmable controller is connected to the industrial control system server via an Ethernet network.

[0020] There are three button switches, namely, a hoisting and unwinding permission button, a unwinding permission button and an emergency stop button. The hoisting and unwinding permission button, the unwinding permission button and the emergency stop button are respectively connected to a programmable controller, and the programmable controller is connected to the industrial control system server.

[0021] The management operation computer is connected to an industrial control system server via an Ethernet network.

[0022] The industrial control system server reads the upper limit switches of the fences of each packaging partition and the switch signals of the lifting and unwinding buttons on the integrated control box in real time through a programmable controller, and performs AND calculation on the two switch signals, stipulating that only one of the lifting and unwinding buttons can be in the on state, and the connecting chain must be connected to the limit switch at the same time, and the overhead crane can enter the packaging area. If one condition is not met, the overhead crane waits.

[0023] See attached Figure 1 In this embodiment, there are three packaging areas, namely packaging areas one to three, and 1# packaging partition fence A1, 2# packaging partition fence B2 and 3# packaging partition fence C3 are installed and fixed outside packaging areas one to three respectively. Three integrated control boxes are respectively provided on the columns of the warehouse area, namely integrated control box B1, integrated control box B2 and integrated control box B3. Integrated control box B1, integrated control box B2 and integrated control box B3 correspond to 1# packaging partition fence A1, 2# packaging partition fence B2 and 3# packaging partition fence C3 respectively. The integrated control box B1, integrated control box B2 and integrated control box B3 have the same structure, and are all equipped with a programmable controller P1, a signal light L1 and a button switch D1. The number of the button switches D1 is three, namely, a hoisting permission button, a unwinding permission button and an emergency stop button.

[0024] The programmable controller P1 is connected to Ethernet E1 for communication, the industrial control system server M1 and the management operation computer M2 are connected to Ethernet E1 for information, and the industrial control system server M1 and the management operation computer M2 are connected by network cables. The programmable controller P1 is installed in each integrated control box, and the communication cables C1 are used for information connection.

[0025] The 1# packaging partition fence A1 is provided with a 1# packaging partition connection fall chain F1 and a 1# packaging partition limit switch 1 matching the 1# packaging partition connection fall chain F1.

[0026] The 2# packaging partition fence B2 is provided with a 2# packaging partition connection fall chain F2 and a 2# packaging partition limit switch 2 matching the 2# packaging partition connection fall chain F2.

[0027] The 3# packaging partition fence C3 is provided with a 3# packaging partition connection fall chain F3 and a 3# packaging partition limit switch 3 matching the 3# packaging partition connection fall chain F3.

[0028] The industrial control system server M1 is located in the electrical room of the unmanned overhead crane, and the management operation computer M2 is located in the operation room of the warehouse area. The overhead crane C2 is connected to the industrial control system server M1 through a wireless AP communication.

[0029] After the information and location of the above components are connected or installed, perform packaging related configuration:

[0030] The management operation computer M2 configures the available configuration of the packaging area and the offline flow of the overhead crane, generates a work order based on the position and status information of the steel coil transmitted from the on-site interface, and sends it to the industrial control system server M1. At the same time, the process control system server M1 sends the operation instruction to the unmanned overhead crane based on the closing status of the on-site limit switch and the status of the switch button on the integrated control box. The overhead crane decides whether to enter or exit the packaging area to perform the operation based on the instruction.

[0031] The specific judgment process is as follows:

[0032] After the industrial control system server M1 generates the offline work order according to the configuration information, the crane C2 operation process first considers whether the packaging area allows the crane to enter and exit the operation. The conditions include: whether there is no steel coil occupied at the first (second or third) unwinding position of the packaging area monitored in real time by the management operation computer M2. When the position allows unwinding, if the steel coil is in the walking beam position, steel coil information, and the crane operation status meet the requirements, such as Figure 1 As shown, the corresponding 1# packaging partition connection fall chain F1 is connected to the 1# packaging partition limit switch 1 (that is, the limit switch is in a closed state), and the unwinding button is allowed to be turned on and in a closed state, a rewinding signal is given, and the signal is transmitted to the programmable controller P1 in the corresponding integrated control box B1, and the programmable controller P1 feeds back the result to the industrial control system server M1. The industrial control system server M1 gives an instruction, and the overhead crane C2 starts to execute the offline packaging work order operation.

[0033] When all packaging areas do not meet the unwinding conditions, the management operation computer M2 will automatically generate a work order for directly hoisting the coils into the warehouse according to the above-mentioned offline workflow configuration. The industrial control system server M1 assigns the work order to the overhead crane C2. The overhead crane C2 will automatically pack the work order and invalidate it according to the work order situation. No packaging operation will be carried out, and the offline warehousing work order will be given priority. When conditions permit, the unpacked steel coils in the warehouse can be hoisted into the packaging area.

[0034] The judgment conditions for generating a work order for lifting the packaged steel coils out of the packaging area and putting them into storage are: the coil lifting permission button gives a coil lifting signal, and at the same time the safety fall chain of the packaging area is connected to the limit switch (that is, the limit switch is in a closed state). The management operation computer M2 will automatically generate a work order for lifting the coils out of the packaging area and send it to the industrial control system server M1. The industrial control system server M1 assigns the work order to the overhead crane C2. At this time, the packaging area connection fall chain cannot be opened. If the overhead crane is lifting the coils in the packaging area, the connection fall chain is opened, which will trigger the overhead crane emergency stop signal to ensure personnel safety.

[0035] During the use of the utility model, when the packaging operator finds that there is a problem with the C2 hoisting roll of the overhead crane or other situations that require stopping the operation, he can press the emergency stop button in the integrated control box in time, allowing the on-site personnel to perform necessary control and manual intervention on the unmanned overhead crane system to ensure safety. The management of other packaging areas is implemented in the same way.
