Description
Technical field
The present invention relates to logistics field, be specifically related to the device of the high wide size detection of a kind of transported substance profile.
Background technology
Transported substance is before entering vertical conveyor or on common pipeline time, and whether need to detect transported substance transfinites at height and width both direction, to ensure the safety of conveying; General, in prior art, high wide checkout gear need to arrange two groups and above correlation photoelectric tube and could realize.
As the appearance detection apparatus of disclosed a kind of tobacco bale in patent CN201420180163.8, comprise checkout gear support, the first checkout gear, second detection device, the 3rd checkout gear and the 4th checkout gear, the first checkout gear and the 3rd checkout gear are a pair of correlation photoelectric tube on sustained height, second detection device and the 4th checkout gear are a pair of correlation photoelectric tube on sustained height, and the height of the aspect ratio second detection device of the first checkout gear is high; By the setting of four pairs of correlation photoelectric tubes, realize the detection to transported substance height and width. But in actual use, the cost of photoelectric tube is higher, in technique scheme, testing is used and relies on photoelectric tube in a large number, makes the cost of this detection mode higher; And photoelectric tube belongs to precision instrument, the work that mainly relies on photoelectric tube realizes and detects effect, makes testing process control loaded down with trivial details.
Summary of the invention
One of object of the present invention be to provide a kind of cost low, manipulate simple mechanical type width detection unit; Two of technical purpose of the present invention is to provide has utilized a kind of appearance detection apparatus in this mechanical type width detection unit.
One of technical purpose of the present invention is achieved by the following technical programs: mechanical type width detection unit, described mechanical type width detection unit comprise base portion be installed, be hinged on detection lance on described installation base portion, for limiting limiting section that described detection lance rotates, described detection lance being applied the elastic part of radial elastic power and is located at the shadow shield with loophole on described detection lance.
In the technical program, by the setting of limiting section, make to detect lance and keep straight down under normal condition; Limit after specification when measured object width exceedes, measured object clashes into and detects lance, makes to detect lance skew; The radial elastic power applying detecting lance by elastic force portion, makes to detect lance and restores; By the setting of shadow shield, make in normal operation, detection signal can be smoothly by described mechanical type width detection unit.
As technique scheme preferably, described limiting section comprises limited impression, described limited impression comprises the first inclined plane and the second inclined plane, the angle that described the first inclined plane, the second inclined plane become is obtuse angle.
Limited impression is the structure with three faces, and the angle on the first inclined plane and the second inclined plane in obtuse angle, the object arranging is like this in normal operation, the first inclined plane and the second inclined plane to detect lance have direction relative against power, keep straight down thereby make to detect lance; And in the time having the state of measured object greater than width restriction, detect lance can from limited impression, be offset smoothly, realize the object of passing through mechanical type width detection unit that stops detection signal.
As technique scheme preferably, described detection lance is hinged on described installation base portion by attachment screw, described attachment screw through described detection lance, base portion be installed be connected with nut.
Detect lance and be hinged on and installed on base portion by attachment screw, making to detect lance can freely rotate taking attachment screw as axle.
As technique scheme preferably, described elastic force portion comprises the Compress Spring being sleeved on described attachment screw.
In preferred technical scheme, the setting of Compress Spring, realization that can be simple in structure is to detecting the reset response of lance.
As technique scheme preferably, described elastic force portion and described detection lance divide and are located at described installation base portion both sides or are positioned at described installation base portion the same side.
As technique scheme preferably, described installation base portion comprises installation base plate and is located at the mounting blocks on described installation base plate; Described limiting section is located on described mounting blocks.
As technique scheme preferably, described installation base portion is provided with and the corresponding locating hole in described loophole position.
In preferred technical scheme, the locating hole that base portion is provided with is installed, the installation site that can accurately calibrate easily described shadow shield, the simultaneously installation site of definite mechanical type width detection unit.
As technique scheme preferably, the hold-down nut that described shadow shield is connected by U bolt and with described U bolt is fixed on described detection lance.
In preferred technical scheme, the hold-down nut that shadow shield is connected by U bolt and with described U bolt is fixed on described detection lance, the advantage arranging is like this can be according to behind locating hole location, by the setting height(from bottom) of accurately adjusting easily shadow shield of U bolt.
As technique scheme preferably, described installation base plate comprises regulating tank, described mounting blocks is through described regulating tank setting.
In preferred technical scheme, the setting of regulating tank can regulate according to the needs of measured object specification the setting height(from bottom) of mechanical type width detection unit.
Two of technical purpose of the present invention is achieved by the following technical programs: a kind of appearance detection apparatus, comprise body frame, also comprise that two are located at the mechanical type width detection unit on described main installing rack and are located on described mechanical type width detection unit for the optoelectronic switch installing rack of optoelectronic switch is installed.
In the technical program, the setting by a pair of correlation sylvatron is to detect measured object height whether in the limited field requiring, and in the time of normal operating conditions, detection signal can pass through mechanical type width detection unit smoothly; Simultaneously by the centre at transmitter and light-receiving device, arrange and detect lance, shadow shield, in the time that the width of measured object exceedes the limited field of requirement, measured object touch and against detect lance, making to detect lance drives shadow shield to be offset, thereby the electronics of transmitter transmitting cannot see through loophole, light-receiving device cannot acknowledge(ment) signal, has realized and has also used same correlation sylvatron to complete width detection. The detection of width converts to and same a pair of correlation fulgurite pipe for height detection mechanically, and this conversion accurately and reliable; Therefore, the technical program only needs a pair of correlation sylvatron can complete the detection to measured object height and two dimensions of width, and cost uses the equipment of multipair correlation sylvatron lower and reliable for effect.
In sum, the present invention has following beneficial effect: manipulation is simple, cost is low, Detection accuracy is high.
