Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
See a kind of belt feeder Full-automatic quantitative distributing device shown in Fig. 1 to Fig. 3, comprise and perform part and control part.Execution part described in the present embodiment, comprise threeway chute size door 8,9, this size door 8,9 two doors are fixed with nut 6 respectively, to be connected with two leading screws 4 that housing is arranged composition transmission device by nut 6, the exit of described two leading screws 4 is connected with respective retarder 3 and motor 1 respectively, coordinates installation handwheel 2 at described retarder 3 other end by key.By retarder 3 and motor 1 controls door and nut does straight reciprocating motion, thus realize the opening and closing of door.Described size door 8,9 is provided with stay wire displacement sensor 5, and the limit switch 7 arranged in two door housings, also comprise belted electronic balance (meaning not shown in the figures).Control part described in the present embodiment, comprise the control box 10 in roll-over, and the wireless transmitter module 11 be provided with in middle roll-over, described control box 10 is connected with distant station PLC 12, this distant station PLC 12 is also connected with main website PLC 14, wherein control box 10 and size door 8, the motor 1 of 9 connects, wireless transmitter module 11, respectively with size door 8, 9 are provided with stay wire displacement sensor 5, current distributor 17, be connected with belted electronic balance by current distributor 17, distant station PLC 12 is connected with wireless receiving module 13, main website PLC 14 is connected with exchange 15 and upper computer 16 respectively.
Principle of work: when material is carried on belt feeder, the belt conveyer scale be placed in below belt conveyor will be weighed in real time to convey materials, and be carried weighing-up wave, for electric-control system belt conveyor scale flow signal.According to field working conditions, weighing-up wave is connected with the wireless module being arranged on middle roll-over by analog quantity shielding wire, receives belt conveyer scale flow signal.In addition, the wireless module in middle roll-over is also connected in order to the displacement pickup detecting warehouse door opening/closing degree with being arranged on working bin threeway chute door, simultaneously the door opening amount signal of received bit displacement sensor feedback.By wireless receiving module in middle roll-over, displacement pickup and belt conveyer scale analog signal are converted into wireless signal, be sent to the wireless receiving module being arranged on switchgear building, and wireless signal is converted into analog signals, be transported to the distant station PLC be attached thereto, distant station PLC transfers signals to Control Room PLC master station by communication cable again, be transferred to monitored control system through exchange again, its main operation interface can show in real time to belt conveyer scale instant flow rate and threeway sub-material chute door position.Preset a point doses by upper computer, door target opening amount signal is transported to main website PLC and distant station PLC more according to this.By the PLC relay output module in distant station, control the intermediate relay (meaning not shown in the figures) be arranged in middle roll-over low pressure control case be attached thereto, then the contactless switch be connected with two motors in working bin is controlled, disconnected by control contactor adhesive, realize two motors and rotate forward reverse function (rotate forward corresponding door to open, the corresponding door that reverses is closed).Namely driven by motor leading screw 4 rotates, but leading screw does not move reciprocatingly, but drives nut 6 to move back and forth by screw mandrel worm drive, and then control size door 8,9 carries out opening or closing according to expected value, realizes quantitative sub-material.In addition, be also provided with limit switch 7 at door housing, limit switch 7 is connected with the contactless switch in low pressure control case 10 in middle roll-over; when size door 8,9 is in the end position of opening and closing, contactless switch disconnects, and motor 1 stops operating; door motion stops, and plays limiting safe protective effect.This is novel by wireless receiving sending module, successfully solves long-distance transmissions construction difficulty.
This novel large I of door aperture realizes optional position by electric machine control and stops, and is realized the detection of door aperture size by door stay wire displacement sensor.
Stay wire displacement sensor is used for detecting door aperture, during installation, by floor installation on door outside frame, bracing wire end is arranged on the traction auxiliary stand being fixed on door that designs, traction check screw is installed on auxiliary stand, to ensure the straight-line trajectory of bracing wire as far as possible simultaneously.
In above-mentioned, drop-gear box end increases handwheel, can realize door and open closedown by M/C, uses as when electrical accident or service personnel maintenance.
Sub-material setting section in control system, by upstream belt balance weighing signal, be converted to the instantaneous flow rate signal of supplied materials, and by flow signal and displacement transducer signal, by wireless transport module, be finally transported to PLC system, be directly presented on Control Room upper computer, according to the demand of two warehouses to doses, the size of setting door aperture.
In addition, consider site operation difficulty, stay wire displacement sensor (being arranged on working bin) current signal and belt conveyer scale (being arranged on band conveyor) weighing-up wave are converted to wireless signal, by wireless transmission/receiver module, 2KM long-distance transmissions farthest can be realized.Wireless transmission/receiver module can say that analog quantity is changed to wireless signal, is converted to analog signals by wireless signal again at receiving end, to PLC Analog input mModule, realizes analog quantity signal collection.
In above-mentioned, utilize PLC relay output module, door opening control signal is transported to the intermediate relay in middle roll-over low pressure control case, relay and then control contactor (being connected with two motors in working bin) adhesive disconnect, realize two motors and rotate forward reverse function, again by machine driven system, control door open and close.
In addition, according to upstream belt conveyer scale instantaneous flow rate signal, and pre-set the demand of two warehouses to stream amount, control two door aperture sizes, control motor by PLC and realize the control of this aperture, and detect door aperture by door displacement pickup, realize position and accurately control.
In above-mentioned, main operation interface (meaning not shown in the figures) can show in real time to belt conveyer scale instant flow rate, threeway sub-material chute door position; Sub-control inerface can recall button at any time, and control inerface is provided with difference in functionality button, can select manually or automatically and long-range/local control, according to the requirement of each warehouse, input door position parameter, regulates door aperture, realizes remote auto and control quantitative sub-material.Meanwhile, there is safety monitoring function at main operation interface also setting tool, can show in real time and automatic alarm also timely cutting-off controlling system circuit when overload, action time-out and displacement pickup fault appear in system.
