End one point mouth shape sampling spade 1-2 of connection and a clamping jaw 1-12, the two can be converted freely, become a mechanical hand, work as object
When material passes through sampled point, sampling spade 1-2 carries out operation, and shovel takes sample and launches to measuring chute 1-3, when sampled point does not have material logical
Out-of-date, mechanical hand is transformed into clamping jaw 1-12 and carries out operation, and the empty sampling tank of specific region is launched onto conveyer belt；Weighing system
Including measuring chute 1-3, the marginal point of the bottom measuring chute 1-3 four is equipped with bracket, and measuring chute 1-3 is maked somebody a mere figurehead transmission belt 1-10's
Top, the measuring chute 1-3 side bottom are equipped with weighing sensor 1-11, and the bottom the measuring chute 1-3 is provided with discharge valve 1-
4, described discharge valve 1-4 mouthfuls communicate with slideway 1-5, and sampling tank 1-9 is limited in the outlet slideway 1-5 lower section, weighing sensor 1-
It is that analog quantity is then transferred to mechanical hand, and mechanical hand itself is that have analog quantity board that 11 function, which is by the weight conversion of material,
, such mechanical hand is known that the weight of each feeding, can be designed according to specific requirements and realize the adjust automatically feeding frequency, adopted
Shovel 1-2 will get material every time and be put into measuring chute 1-3, and when weight reaches requirement, master controller receives mechanical hand sending
Expect that full signal control discharge valve 1-4 is automatically opened, the material in such measuring chute 1-3 is entirely fallen under discharging valve port by slideway
In sampling tank 1-9；Transmitting device includes multistage transmission belt 1-10, pneumatic gate valve 1-8 and two photoelectric sensors, pneumatic gate valve by
Cylinder and gate structure composition, pneumatic gate valve 1-8 are used to limit the sampling tank 1-9 of front end sky below 1-4 mouthfuls of discharge valve, when
After material completely falls into sampling tank 1-9, main controller controls cylinder, which is shunk, pulls in gate 1-8 below conveying roller, until there is material to adopt
Main controller controls cylinder stretching so that gate 1-8 continues to intercept next vacant sampling tank 1- again after sample bucket passes through gate 1-8
9, and multistage transmission belt 1-10 is made of motor and idler wheel, the multistage two sides transmission belt 1-10 are equipped with shelves part, can prevent sampling tank
It falls down, sets in entire transmission process there are two photoelectric sensor when moving unstable, selection Germany west gram SICKWTB12-
The product of 3P2431 model, one 1-6 of photoelectric sensor are used in respect of the quantity in material sampling tank, and two 1-7 of photoelectric sensor is used to
Judgement has whether material acquisition bucket is accumulated excessively；Alarm system is detected by temperature sensor, limit sensors and alarm lamp

And the composition such as configuration monitoring software, it is wireless data communication product that radio transmitting device, which is selected as DTD434M up to safe 4, scene
For master controller by wireless launcher sending and receiving data, corresponding distal end PC is also that live master control is received and dispatched by wireless launcher
The purpose in remote control field device may be implemented by record to these data and transmission in the data of device processed.
Workflow is as follows:
(1) configuration monitoring system first on distal end manipulation chamber opening PC, feeding number needed for setting sampling, when
Between be spaced and parameters, the click such as sample weight are automatically begun to, or directly controlled and started by button at the scene.
(2) before mechanical hand starts feeding, it can judge whether to have material on the belt of upstream by sensor detection and system is
It is no normal.
(3) it produces if normal, this signal can be given to robot board by sensor, and robot captures timing one after this signal
Then the section time starts to control sampling spade work, it is ensured that sintering building stones are transferred to sampled point, start if not producing and waiting for production.
(4) sintering building stones are transmitted to sampled point, and mechanical hand executes sampling feeding action since origin, and end samples back chipping
Reach effective feeding according to the path movement set.
(5) after the completion of sampling spade feeding, mechanical hand need to return to feeding point, need a back and forth movement by a small margin to shake
Unstable sintering building stones are fallen, material is unrestrained when preventing from transporting, and then mechanical hand moves to sampling spade above measuring chute, at this time can
Do a protection judgement, it is necessary to which returning to emptying point could continue to operate below, prevent discharging from malfunctioning.
(6) the normal feeding of mechanical hand is complete returns to emptying point, starts to adjust sampling spade discharging to measuring chute.
(7) there is weighing sensor real-time monitoring feeding weight under measuring chute, and send the data to robot, master controller
It can read the parameter being arranged on the PC of distal end, the frequency signal for being converted into feeding action feeds back to mechanical hand, and mechanical hand is compared with this
Judge whether to need to increase and decrease crawl number；Such as wherein primary crawl is sky, weighing system can be allowed after monitoring mechanical hand immediately
It grabs again once without doing delay disposal.
(8) when the weight of the material sampled in measuring chute reaches the weight of 15KG or setting, due to weighing sensor meeting
Weight data is issued into mechanical hand in real time, mechanical hand can send one at this time and expect full signal to master controller, and master controller passes through
The cylinder of the discharge valve below measuring chute is controlled to open valve, the material in measuring chute is put into sampling tank, is then slightly prolonged
The sampling tank for having got material is released in slow main controller controls gate cylinder contraction, and sampling tank is passed by transmission movement, Deng Daoqian
When the empty sampling tank in side comes fastly, master controller stops transmission belt, so that gate cylinder is stretched out, blocks empty sampling tank.
(9) quantity information is fed back to master controller by counting photoelectricity by the sampling tank for filling wanted weight material, and is passed
It is defeated to take there are one preventing from piling with alarm photoelectric sensor, a switching value letter can be sent when this photoelectric sensor is triggered
Number give master controller, illustrate to have material sampling tank accumulated it is excessive need processing in time, master controller can control live alarm
Lamp alarm, and send this important alarm condition on the PC of distal end, it is shown by configuration picture, master controller can monitor this simultaneously
Whether the corresponding control mechanical hand of the state of road alarm needs to work on.
(10) the empty sampling tank in a certain region can be put into transmission belt by the clamping jaw on sampling spade and uploaded by mechanical hand
It send and gate is allowed to stop empty sampling tank that sampling discharging next time is waited to act to the lower section of discharge valve slideway mouth.
(11) when the sampling tank of charging reaches certain amount (such as 4, can adjust according to demand), system, which provides, takes bucket to mention
Show and sample-grabber is allowed to go to take, if it exceeds certain amount does not take also, corresponding alarm behaviour is provided by accumulation photoelectric sensor above
Make.
