Detailed description of the invention
Attached drawing 1 is electrical block diagram of the invention；
In figure: 1, man-machine interface；2, the first connection；3, programmable logic controller (PLC)；4, the second connection；5, electronic scale.
Specific embodiment
By the technology contents of invention are described in detail, construction feature, are reached purpose and efficacy, simultaneously below in conjunction with embodiment
Cooperation attached drawing is described in detail.
Pipe production line generally includes extruder, extrusion die, molding die, cooling device, cutter device, conveyer belt,
On the conveyer belt of pipe production line, qualified products receipts are respectively set stirring set-up of control system of the invention in the two sides of conveyer belt
Expect device and substandard product material collecting device, is respectively used to store qualified tubing and unqualified tubing.
Referring to Fig. 1, the present embodiment discloses a kind of stirring control system for pipe production line, including man-machine interface 1, can
Programmed logic controller 3, electronic scale 5, positioned at conveyer belt side the first pusher cylinder (not shown), be located at conveyer belt it is another
Second pusher cylinder (not shown) of side and the first solenoid valve being connected with the first pusher cylinder and the second pusher gas
The connected second solenoid valve of cylinder.Man-machine interface 1 is connect by the first connection 2 with programmable logic controller (PLC) 3,5 band of electronic scale
Modbus RTU communications protocol, electronic scale 5 is connect by the second connection 4 with programmable logic controller (PLC) 3, in the present embodiment
Second connection 4 is Modbus connection, and Modbus can be used ascii mode or RTU mode, in the present embodiment using
RTU mode, the major advantage of the mode are that the density of its character transmitted under identical baud rate is higher than ascii mode, often
A information must continuously transmit.Programmable logic controller (PLC) 3 is also connect with the first solenoid valve and second solenoid valve signal, to divide
The first pusher cylinder and the movement of the second pusher cylinder are not controlled, and then sieve tubing according to testing result.Programmable logic simultaneously
Controller 3 is also used to record the total quantity of cutter device incising pipes on production line, the quantity of qualified tubing and weight, unqualified
The creation datas such as tubing quantity and weight.
The screen of man-machine interface 1 in the present embodiment uses touch screen, and programmable logic controller (PLC) 3 uses Siemens
S7200 PLC(6ES7 214-2AD23 or 6ES7 216-2AD23), programmable logic controller (PLC) 3 has 2 communication interfaces.
Working principle of the invention is as follows: the weight range of qualified tubing being arranged first in man-machine interface 1, including in weight
A and lower weight limit b is limited, the tubing of well cutting can be endlessly sent into conveyer belt by tubing production process, and cutter device is often cut
When cutting one root canal material of completion, programmable logic controller (PLC) 3 reads the weight c of pipe finished, programmable logic control from electronic scale 5
Device 3 processed reads the weight range for the qualified tubing being arranged in man-machine interface 1, and compares weight c and the conjunction of setting of finished product tubing
The weight range of lattice tubing, if c < b or c > a, programmable logic controller (PLC) 3 judge that the tubing belongs to substandard product,
The pipe finished is pushed into substandard product rewinding dress by the second pusher cylinder movement for sending a signal to second solenoid valve control
It sets, if b≤c≤a, programmable logic controller (PLC) 3 judges that the tubing belongs to qualified products, that is, sends a signal to the first solenoid valve
The movement of the first pusher cylinder is controlled, which is pushed into qualified products material collecting device.Since the device is arranged in pipe production line
On, may be implemented the real-time detection of tubing weight, and can the qualified tubing of timely automated packing and unqualified tubing, production efficiency
It is high.
The present invention can also realize product counting and qualification rate statistics: under original state, programmable logic controller (PLC) 3 is remembered
Quantity d=0 of the tubing of the cutting of record, quantity e=0 of qualified products, substandard product quantity f=0, the every cutting of cutter device
One root canal material after programmable logic controller (PLC) 3 detects cutoff signal, records the quantity d+1 of the pipe finished of cutting, according to above-mentioned
When method programmable logic controller (PLC) 3 judges tubing for qualified products, the quantity of qualified products is e+1, Programmable logical controller
When device 3 judges tubing for substandard product, the quantity of substandard product is f+1, and programmable logic controller (PLC) 3 records at the same time
Under every root canal material weight c, after the completion of cutting, programmable logic controller (PLC) 3 handles data, be calculated yields and
Fraction defective.The weight c of every pipe finished, every pipe finished determine acceptance or rejection, the yields being calculated and not
Yield can show on the screen of man-machine interface 1, check for manager.
Manager can judge whether current processing parameter is suitable by fraction defective, if fraction defective is excessively high,
Or when unqualified counting continuous counter, then the adjustment of technological parameter will be carried out, to reduce the general of substandard product at once
Rate.Guarantee quality, the purpose of save the cost to reach raising.
Compared with traditional control method, for the present invention for carrying out tubing detection online, timeliness is good, and screening packing in time
Qualified finished product and rejected product, rejection rate statistical work are completed in real time, are shifted without manual handling, operation and maintenance is simple, is
Stability of uniting is good.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art's energy
The solution contents of the present invention much of that are simultaneously implemented accordingly, and it is not intended to limit the scope of the present invention.It is all spiritual according to the present invention
Made equivalent change or modification, should be covered by the protection scope of the present invention.
