Abstract
The utility model relates to the field of tracking of strip steel heads and in particular relates to a device for tracking and detecting a strip steel head. The device comprises a pinch roll, a winding drum and a pressure sensor. The device is characterized in that a light curtain detection device is arranged between the pinch roll and the winding drum and comprises a light ray transmitter and a light ray receiver which are respectively arranged at two sides of a strip steel channel; and a light path between the light ray transmitter and the light ray receiver is perpendicular to a strip steel surface. Compared with the prior art, the device for tracking and detecting the strip steel head has the beneficial effect that light curtain detection and pressure change detection can be mutually converted under certain conditions, the accident of steel clamping caused by disturbance of a hydraulic system, emergency switching of pressures by a coiler and damage of a pressure sensor is avoided, and the starting rate of the device and the production operation rate are improved.
Description
Technical field
The utility model relates to band steel toe portion and follows the tracks of the field, relates in particular to a kind of band steel toe portion tracing and detecting apparatus.
Background technology
In order to reduce coil of strip head impression; General hot-rolled strip production line coil wrapper roll then adopts automatic leapfrog control in band steel toe portion; And be that the variation of the pressure sensor feedback pressure installed with coiling machine pinch roll hydraulic cylinder is defined to the following calculation of band steel toe portion; This method has the advantage that does not receive such environmental effects such as steam, receives the hydraulic system disturbance to produce the shortcoming of misoperation but also have, and the equipment of influence starts rate and production operational availability.
Summary of the invention
The purpose of the utility model provides a kind of band steel toe portion tracing and detecting apparatus; Overcome the deficiency of prior art; Adopting light curtain checkout gear to detect with pressure change combines; Avoid promptly switching the steel-fastening accident generation that reasons such as pressure variation, pressure sensor damage cause, improve production operational availability because of hydraulic system disturbance, coiling machine.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Band steel toe portion tracing and detecting apparatus; Comprise pinch roll, reel, pressure sensor; Between pinch roll and reel, be provided with light curtain checkout gear; Said light curtain checkout gear comprises that light emitters and light receiver are separately positioned on the both sides of band steel passage, and the light path between light emitters and the light receiver is perpendicular to belt steel surface.
Compared with prior art; The beneficial effect of the utility model is: the light curtain detects with the pressure change detection and can change each other under certain condition; Avoid promptly switching the steel-fastening accident generation that reasons such as pressure variation, pressure sensor damage cause because of hydraulic system disturbance, coiling machine, raising equipment starts rate and production operational availability.

The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Seeing Fig. 1, is the utility model band steel toe portion tracing and detecting apparatus example structure sketch map, comprises pinch roll 1, reel 2, pressure sensor 3; Between pinch roll 1 and reel 2, be provided with light curtain checkout gear 4; Light curtain checkout gear 4 comprises that light emitters 5 and light receiver 6 are separately positioned on the both sides of band steel 7 passages, and the light path between light emitters 5 and the light receiver 6 is perpendicular to band steel 7 surfaces, and pressure sensor 3 is carried out pressure change and detected; When continuing to adopt the pressure change detection system; Increase measuring light curtain checkout gear 4, when because factors such as pressure variations, pressure sensor damage are promptly switched in hydraulic system disturbance, coiling machine pressure change being detected when invalid, measuring light curtain detected state is put in the control program switching; Band steel 7 heads cut off light path through pinch roll 1; When the logical light rate of measuring light curtain reached setting value, measuring system was sent band steel toe portion arriving signal to carry out the leapfrog following calculation, helps winding up roller 8 to open the band steel is pressed in reel 2 surface beginning roll bendings.
