Description
Technical field
The utility model relates to the big roll bending bands of metal in process of production, to guarantee product surface quality, while effectively
Automated production control is realized on ground, improves production efficiency, in unit production process, controls system according to fixed length principle combination PLC
System realizes a kind of self-stopping technology, specially fixed length automatic stopping control system after the completion of production.
Background technique
In metal plates and strips production process, the units machine alignment such as general cleaning, stretch-bending straightening, shearing is all long,
And some units also need quantity-produced products of volume two by suture or are welded to connect by producing unit, and this will
Asking the position of tail band when stopping after completing to produce will prepare to be parked at suture or welder, and end speed is too fast is difficult to ensure for production
Tail stop with position, while quickly throwing away tail band and also product quality and equipment being caused to damage；Production end speed spends slow influence again
To production efficiency.
Summary of the invention
In order to accurately control parking opportunity in process of production, the utility model provides a kind of fixed length automatic stopping control
System processed.
The utility model adopts the following technical scheme that realization: fixed length automatic stopping control system, including metering instrument
With the encoder installed on the rectification roll before product batches, encoder is connected with metering instrument, metering instrument and machine set PLC control
System processed connects, and length comparison program is written in metering instrument (length comparison program is program well known in the art).
Rectification roll is operated with production in process of production, and the velocity of rotation that encoder detects is by encoder with pulse signal
It is transferred to metering instrument；Metering instrument umber of pulse n according to received by rectification roll rotation one week, obtains the length of each pulse
P=L/n, L are the perimeter of rectification roll, and metering instrument calculates the reality that coiled material passes through in production process eventually by the umber of pulse m of record
Border length mP；Operator can calculate this according to the weight of coiled material, the thickness of product, width, internal-and external diameter, density parameter
The total length of coiled material, and input in metering instrument；Operator inputs reduce-speed sign value in metering instrument simultaneously；Metering instrument
The physical length mP passed through in the total length of the coiled material of input and production process is compared, when the difference of the two reaches subtracting for input
When fast signal value, metering instrument issues reduce-speed sign to the PLC control system of unit；PLC control system carries out ladder to system
Formula is slowed down, and detects i.e. parking after uncoiling mistake after reaching creep speed.
Use fixed length automatic parking system, it is necessary to guarantee pulse signal that metering instrument receives and operator according to
The theoretical total length of calculating input is accurate, and (according to long-term production experience, operator is by the weight of coiled material, the thickness of product, width
It is quite accurate that degree, internal-and external diameter, density parameter calculate the theoretical total length got), and understand common speed during normal production
The size (i.e. PLC is connected to the speed produced before reduce-speed sign) of degree, speed is down to creep speed and is not grown when just can guarantee parking
Time produces under the state of creeping, that is, improves production efficiency, in turn ensures that product and equipment are not damaged.
Automatic stopping can be realized in the signal that the utility model increases counting meter in original control system, practical
It is convenient, it greatly increases the production efficiency, while avoiding the damage of product quality and equipment.
Detailed description of the invention
Fig. 1 is the control flow chart of fixed length automatic stopping control system.
Specific embodiment
Fixed length automatic stopping control system, including metering instrument and the coding installed on the rectification roll before product batches
Device, rectification roll is operated with production in process of production, and the velocity of rotation that encoder detects is by encoder with pulse signal transmission
Give metering instrument；Metering instrument obtains each pulse P according to the perimeter L of rectification roll by the step-by-step counting transmitted to rectification roll
Length, calculate the physical length that coiled material in production process passes through by recording impulse number and in conjunction with the calculation formula of input；
Operator can calculate this coiled material according to the weight of coiled material, the thickness of product, width, internal-and external diameter, density parameter simultaneously
Total length, and input in metering instrument；Operator inputs reduce-speed sign value in metering instrument simultaneously, that is, sets a calculating
Total length and the practical difference by length, i.e., according to calculated value, on uncoiler remaining band length；Meter
Meter Yi Biao compares the total length of the coiled material of input with the physical length passed through in production process is calculated, when the difference of the two reaches
When the reduce-speed sign value of input, metering instrument issues reduce-speed sign to the PLC control system of unit；PLC control system is to system
Staged deceleration is carried out, detects i.e. parking after uncoiling mistake after reaching creep speed.
The staged of PLC control system is slowed down, and is to input the unit time in system by electrical control personnel to reduce
Velocity amplitude, velocity amplitude when being connected to signal with PLC in actual production is unrelated, is connected to the control system of signal according to the deceleration of input
Rate reduces speed of production, until speed reaches creep speed, the i.e. minimum speed of equipment operation, then proceedes to operation until uncoiling
Coiled material on machine all unclamps, and loses and stops after opening.
