Abstract
The utility model relates to a strip steel edge searching device. Photoelectric sensors arranged on two sides of strip steel are connected with a PLC via a digital value input module, and the output module of the PLC is connected with an electromagnetic valve on a compressed air pipe line used for driving a pneumatic beam. Signals fed back from the photoelectric sensors are collected and converted by the digital value input module, and the PLC accurately judges and positions the edge parts of the strip steel according to different states of light sources shielded by the strip steel, so as to realize the edge searching function. Meanwhile, the PLC controls the output module to adjust the opening degree of the electromagnetic valve on the compressed air pipe line and control the traveling of the pneumatic beam, so as to suit the detection of strip steel with various widths. The utility model has simple structure, investment conservation, high efficiency and convenient maintenance, thereby being applicable to the positioning control of the traveling of various mechanical actuating mechanisms.
Description
Technical field
The utility model belongs to automatically controlled checkout gear, relates in particular to a kind of cold-rolled steel strip continuous annealing production line to the less demanding strip edge of control accuracy position detection device.
Background technology
At present, cold-strip steel continous way anneling production line all has a lot of needs accurately to detect the equipment of determining strip edge portion position (being that what is called is sought the limit) both at home and abroad, as purge beam, smooth liquid spray beam, dig the limit and equipment such as cut, though these equipment are less demanding to strip edge portion control accuracy, but need exactly strip edge portion to be positioned the mechanical action that can reliably put rules into practice exactly, realize predetermined function.At present institute generally uses, and to seek frontier inspection survey device be encoder or photoelectric detection switch, though also can satisfy the needs that the band steel is sought the limit, frontier inspection survey device all exists one-time investment and maintenance cost is higher but these are sought, and complex structure is not easy to defectives such as maintenance and repair.Especially photoelectric detection switch, after welding together for two kinds of different in width band steel, because the width difference must frequently be adjusted the photoelectric detection switch position when therefore detecting and could detect smoothly, not only time-consuming but also require great effort, directly have influence on the direct motion that continuous annealing is produced.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple, is convenient to safeguard, can accurately locate the edge searching device of strip edge portion position.
For this reason, the solution taked of the utility model is:
A kind of band steel edge searching device is made up of pneumatic beam, photoelectric sensor and digital quantity input module; The photoelectric sensor of being located at band steel both sides is installed on the fixed support by connecting plate respectively, the "T"-shaped head in fixed support upper end is slidingly connected in the slideway of pneumatic beam, photoelectric sensor connects original annealing furnace district programmable logic controller (be called for short PLC) by digital quantity input module, and the magnetic valve on the compressed air piping of the output module of PLC and the pneumatic beam of driving is connected.
Described photoelectric sensor comprises correlation type photoelectric sensor, reflection template photoelectric sensor and diffuse reflection type photoelectric sensor; The photoelectric sensor of band steel both sides adopts the form that sets up or be provided with in pairs up and down at the band steel.
The utility model utilizes digital quantity input module that the signal of photo-sensor feedback is gathered and changed, and the PLC programmed logic is judged strip edge portion position according to the different conditions that the band steel blocks transmitting illuminant, accurately locatees strip edge portion position, realizes seeking the limit function.Simultaneously, PLC also by the magnetic valve aperture on the output module adjusting compressed air piping, controls dividing a word with a hyphen at the end of a line of pneumatic beam, thereby the band steel that adapts to various width specifications is sought the frontier inspection survey.The utility model is simple in structure, reduced investment, instant effect, and maintenance cost is low, and is convenient to maintenance, can be applicable to the positioning control of mechanical actuating mechanism traveling.
Description of drawings
Fig. 1 is band steel edge searching device structured flowchart.
Fig. 2 is photoelectric sensor installment state figure.
Among the figure: pneumatic beam 1, fixed support 2, connecting plate 3, band steel 4, photoelectric sensor 5.
The specific embodiment
As seen from Figure 1, the utility model mainly is made up of pneumatic beam 1, photoelectric sensor 5, digital quantity input module and PLC.The photoelectric sensor 5 of being located at pneumatic beam 1 below connects PLC by digital quantity input module, and PLC connects with magnetic valve on the compressed air piping that drives pneumatic beam 1 simultaneously, controls dividing a word with a hyphen at the end of a line of pneumatic beam 1 by the output module of PLC.
Fig. 2 shows that photoelectric sensor 5 is fixed on the connecting plate 3, and 3 of connecting plates are installed on the fixed support 2, and the upper end of fixed support 2 has "T"-shaped head, and "T"-shaped head is movably arranged in the slideway of the pneumatic beam supporting setting in 1 bottom, and can slide along slideway.
Photoelectric sensor 5 is divided into correlation type photoelectric sensor, reflection template photoelectric sensor and three kinds of forms of diffuse reflection type photoelectric sensor, therefore the photoelectric sensor 5 of being located at band steel 4 both sides is also according to the different set-up modes that adopt two kinds of correspondences of shape system, promptly adopt on the band steel or below the form that sets up or be provided with in pairs up and down at the band steel.Take as shown in Figure 2 form for correlation type photoelectric sensor, band steel 4 both sides, above the band steel 4 and below a pair of photoelectric sensor 5 is set; For reflection template photoelectric sensor and diffuse reflection type photoelectric sensor only then take band steel 4 both sides, above the band steel 4 or below a set-up mode that reflects a template photoelectric sensor or a diffuse reflection type photoelectric sensor is set separately.
