Summary of the invention
The purpose of this utility model is to provide a kind of fault memory type safety to cross belting, to reduce or to avoid the generation of broken belt, deviation phenomenon.
The technical solution of the utility model is achieved in that designing a kind of fault memory type safety crosses belting, and it comprises coiling machine 1, slewing rollers 2, main mill 3, support roller 4, goes up coil unloading carriage 9; Main mill 3 both sides have left and right sides coiling machine 1 respectively, between main mill 3 and the left and right sides coiling machine 1 left and right sides slewing rollers 2 are arranged; Coil unloading carriage 9 is gone up about being respectively in coiling machine 1 bottom side in the left and right sides; Left and right sides coiling machine 1 is connected with 7 of left and right sides coiling machine reductors respectively, and reductor 7 is by being connected by motor-driven with motor 8; It is characterized in that: on slewing rollers 2, motor 8 connecting axles and last coil unloading carriage 9, displacement measuring device 5 is arranged; Displacement measuring device 5 is electrically connected with control executing agency 6 respectively; Control executing agency is electrically connected with the driving mechanism of 6 coiling machines 1.
Described displacement measuring device 5 is incremental optical-electricity encoders.
Described control executing agency 6 comprises that controller PLC and executing agency form, and above-mentioned incremental optical-electricity encoder output is electrically connected with controller PLC input; Controller PLC output is electrically connected with motor 8.
Characteristics of the present utility model are: owing at slewing rollers 2, motor 8 connecting axles displacement measuring device 5 is arranged; Displacement measuring device 5 is incremental optical-electricity encoders, and it is electrically connected with control executing agency 6 respectively; Control executing agency 6 is electrically connected with the driving mechanism of coiling machine 1.Store the position of the fault of 6 pairs of roll coil of strips of control executing agency, when the fault district is by the rolling deformation district like this, the speed of the control executing agency 6 restriction roll coil of strips, and multi-pass fault district can adopt automatic merging when nearer of passage transmission downwards, adjacent fault interval automatically, guarantee with qualification speed by functions such as fault districts at fault arrival prerequisite front reduction gear in multi-pass reversible processing unit.Make this method feasible, reliable, and simple to operation when reality is used.In actual applications respond well.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the example structure schematic diagram.
Among the figure, 1, coiling machine; 2, slewing rollers; 3, main mill; 4, support roller; 5 displacement measuring devices; 6, control executing agency; 7, reductor; 8, motor; 9, go up coil unloading carriage; 10, the roll coil of strip.
The specific embodiment
Embodiment as shown in Figure 1, it comprises coiling machine 1, slewing rollers 2, main mill 3, support roller 4, goes up coil unloading carriage 9; Main mill 3 both sides have left and right sides coiling machine 1 respectively, between main mill 3 and the left and right sides coiling machine 1 left and right sides slewing rollers 2 are arranged; Coil unloading carriage 9 is gone up about being respectively in coiling machine 1 bottom side in the left and right sides; Left and right sides coiling machine 1 is connected with 7 of left and right sides coiling machine reductors respectively, and reductor 7 is by being connected by motor-driven with motor 8; It is characterized in that: on slewing rollers 2, motor 8 connecting axles and last coil unloading carriage 9 displacement measuring device 5 is arranged, displacement measuring device 5 is incremental optical-electricity encoders.Displacement measuring device 5 is electrically connected with control executing agency 6 respectively; Control executing agency 6 comprises that controller PLC and executing agency form, and above-mentioned incremental optical-electricity encoder output is electrically connected with controller PLC input; Controller PLC output is electrically connected with motor 8.
Left and right sides coiling machine 1 has the long or note circle function of note because incremental optical-electricity encoder is arranged.Long inaccurate in order to prevent unit note under situations such as loose winding, sliding band, the method for taking usually to remember circle identifies fault.The resolution ratio of supposing incremental optical-electricity encoder is F, and the speed reducing ratio of the reductor 7 of left and right sides coiling machine 1 is N, and the counter currency is R, and then current number of turns position is:
Can select for use a decimal to demarcate length (number of turns) position in fault district in this number of turns value.In first passage or use before fault memory safety crosses the band function, must demarcate length (or number of turns) position of each fault.Operation or automatically the fault memory system determine blank when entering the fault district, then give a logic switch amount home position signal, the PLC system writes down current length (or number of turns) value (starting position in fault district) of batching side, the fault district by after the corresponding signal that resets again, PLC writes down position (end position in fault district) at that time simultaneously.Analogize by this and can in a passage, demarcate a plurality of faults district.
The fault district during by the rolling deformation district unit automatic speed-limiting pass through.When fault memory type safety is crossed the band function and is devoted oneself to work.Current number of turns actual value and fault memory value that controller PLC reads current uncoiling side in real time compare, in the time will entering the fault district, controller PLC control deceleration in advance and speed limit are by fault district (the deceleration lead can be adjusted), after judging that according to the number of turns fault district tail end passes through, unit begins raising speed and returns to by the unit operation speed before the fault.
The fault zone position is passage transmission downwards automatically.When the uncoiling side entered the fault district, controller PLC judgement automatically provided signal, will batch the current number of turns memory storage (as the end point in the following current fault of passage district) of side.When the uncoiling side judged that the fault district has passed through, controller PLC provided signal equally, will batch the current number of turns memory storage (as the starting point in the following current fault of passage district) of side.So analogize all the fault districts that current pass can be remembered, pass to down a time, and do not processed the influence that the roll coil of strip extends.
