Abstract
The utility model provides a fault protector for belts, which comprises a detection board moving along with a belt, an approach switch and a PLC. The utility model adopts the approach switch and makes full use of the control function of the PLC, the detection to the operation condition of the belt is realized, the fault belt can be checked and repaired in time, and the enlargement of the accident is avoided.
Description
Technical field
The utility model relates to a kind of belt failure protecting device, relates in particular to the belt failure protecting device of a kind of PLC of utilization (Programmable Logic Controller).
Background technology
In enterprises such as washery, cokerys, in the operational process of the manufacturing line that uses belt to transmit, the belt failure problems often appears.When skidding appears in drive belt; the tour personnel are not in place and can not in time take safety method; very easily cause the severe wear or the fracture of belt or transport thing and kill belt; thereby cause the system-wide disaster shutdown and influence the normal operation of whole production line, this may have a strong impact on the progress and the efficient of production.
Therefore, cause the damaged condition of production facilities, need provide a kind of economic, practical device to detect and provide protection/warning the belt fault for preventing the belt fault.
The utility model content
In order to realize the timely detection and the protection of belt fault, the utility model proposes a kind of belt failure protecting device.
This device comprises that a metal detection plate, one are near switch and a PLC, described metal detection plate is installed on the passive cylinder of belt machine end, describedly be installed near the aircraft tail cylinder base in the distance of reaction near switch, described PLC links to each other near switch with described, and described PLC comprises judge module, when PLC receives the impulse singla that sends near switch in the setting-up time section, judge module judges that belt is a normal operation, otherwise the judgement belt is owed speed, and PLC sends prompting or warning signal.
Preferably, described check-out console is a circular arc iron plate.
Preferably, described check-out console is installed on the inwall of the passive cylinder of belt machine end.
Preferably, described PLC links to each other with the belt feeder actuating device simultaneously, and the PLC controller sends halt instruction to the belt feeder actuating device when judging that belt is owed speed.
The utility model adopts near switch and has made full use of the controllable function of PLC, can realize the monitoring to the belt fault, when having realized the belt et out of order simultaneously to the protection of equipment.Therefore, the utility model device applying flexible, its enforcement not only can reduce the economic loss that the damage of the production facilities that causes because of the belt fault in the production brings, and has also guaranteed carrying out smoothly of the safety of producing and ordinary production.
Description of drawings
Read in conjunction with the accompanying drawings, the detailed description of specific embodiment of the utility model is more readily understood.In the accompanying drawing:
The principle of work scheme drawing of Fig. 1 the utility model embodiment belt failure protecting device.
The specific embodiment
The utility model embodiment is the device that is used for the belt emergency protection.The check-out console that present embodiment is installed on the cylinder is a circular arc iron plate, and certainly, this check-out console also can be other shape, and its shape and mounting means should not influence the normal operation of belt system.In the present embodiment, check-out console is installed on the passive inner wall of rotary drum of belt machine end.Certainly, this check-out console also can be installed in other position, as long as it is just passable to draw belt speed according to the speed of check-out console.Be installed near periodically to sense the check-out console action the passive cylinder of tail the scope near switch.Should link to each other with a PLC near switch.
Below with reference to Fig. 1 mode of operation of the present utility model is described:
During the belt normal operation, check-out console periodically near near switch, is passed to the PLC impulse singla near switch periods, judges when PLC receives the impulse singla that sends near switch in the setting-up time section that belt is a normal operation.
When the belt fault takes place, belt speed changes, and check-out console is as can not be near near switch in the setting-up time section, and PLC does not receive impulse singla in the setting-up time section, judge that then belt owes speed and send prompting or warning signal, remind the timely handling failure of operating personal.
This PLC also can link to each other with the belt feeder actuating device simultaneously, when judging et out of order, sends halt instruction to the belt feeder actuating device.
Claims (4)
1, a kind of belt failure protecting device; it is characterized in that; this device comprises that a metal detection plate, one are near switch and a PLC; described metal detection plate is installed on the passive cylinder of belt machine end; describedly be installed near the aircraft tail cylinder base in the distance of reaction near switch; described PLC links to each other near switch with described; described PLC comprises judge module; when PLC receives the impulse singla that sends near switch in the setting-up time section; judge module judges that belt is a normal operation; otherwise the judgement belt is owed speed, and PLC sends prompting or warning signal.
2, belt failure protecting device according to claim 1 is characterized in that, described check-out console is a circular arc iron plate.
