Description
Technical field:
The utility model relates generally to the color selector technical field, relates in particular to a kind of color selector Background apparatus.
Background technology:
Color selector is the difference according to the material optical characteristics, the equipment that utilizes photoelectric technology that the heterochromatic particle in the granule materials is sorted out automatically.The operation principle of color selector is the hopper entering machine of sorted materials from the top, through the vibration of vibrating device, enters into the observation district in the separation chamber along long and narrow transmission skewed slot, and between sensor and background board, passes; The high stable light source and high sensitivity photodetector (photoelectric sensor/CCD camera) acting in conjunction that are installed in the separation chamber are compared with the light quantity of passing through coloured light the reverberation of the material that detects with the benchmark light quantity; Utilize the color distortion between sorted materials and the reference colours to identify heterochromatic grain; And with the difference processing and amplifying of its signal; When signal difference during greater than predetermined value, the drive air spraying system is rejected heterochromatic grain, to reach the purpose of sorting.
Background board in the existing color selector Background apparatus is a kind of to be the two end supports monoblock type, for the passage aisle color selector, because the complete machine width is less; The length of background board is also short, and intensity of himself and rigidity can meet the demands, but for the major path color selector; The complete machine broad, the distortion of two end supports monoblock type background board is bigger, when equipment during in operate as normal; The vibration of complete machine can cause the vibration of background board; Especially after jolting through transportation, plastic deformation can take place in background board, causes the uniformity of self signal to be difficult to guarantee.Perhaps change in case benchmark is unstable, will have a strong impact on look and select effect.
For addressing the above problem, existing way is that background board is designed to segmented, between two sections background boards, is connected with bracing frame through little axle; Satisfy the background board requirement of strength to reach, but see through the jockey that material is seen segmented background board midfeather place, generally can increase by the two adjacent channel spacings that background board segmentation place is corresponding for fear of photodetector; Photodetector detects jockey if this is; Will change the material reference data, can cause the mistake of benchmark light quantity, particularly when photodetector is CCD; Because the visual field broad that CCD sees; The interval of adjacency channel is bigger, has sacrificed port number so virtually, and complete machine output has been caused negative effect.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of color selector Background apparatus to be provided, and it can guarantee the intensity of background board, can victim way quantity, can not influence the precision of color separation and the reliability of color selector.
The utility model is realized through following technical scheme:
A kind of color selector Background apparatus; Include the background panel seat; The left and right two ends of said background panel seat are respectively equipped with left and right support, are rotatablely equipped with left and right rotating shaft on the left and right support respectively, are installed with background board between the said left and right rotating shaft; It is characterized in that: on the said background panel seat bracing frame that is used to support background board is installed; Support frame as described above is provided with the cross section and is circular supporting surface, and the center line of said supporting surface overlaps with the rotation of background board, on the support frame as described above in the corresponding color selector zone of detector field of view be made as open loop.
A kind of color selector Background apparatus is characterized in that: said left and right rotating shaft is rotated through gear drive, chain transmission or band transmission control.
A kind of color selector Background apparatus; It is characterized in that: the left end of said left rotary shaft and the right-hand member of right spindle fixed cover respectively are equipped with left and right gear; Be rotatablely equipped with respectively the travelling gear with left and right meshed transmission gear on the said background panel seat, rotate through Electric Machine Control with the travelling gear of left gear engaged transmission.
A kind of color selector is used Background apparatus, it is characterized in that: support frame as described above is supported on the middle part of background board.
Whether consistent a kind of color selector is used Background apparatus, it is characterized in that: be equipped with on the background panel seat and be used to feed back angle that background board rotates and desired angle potentiometer.
The zone of detecting on the background board owing to photodetector is not whole, and is one of them narrower face, can be detected with regard to the significant surface that only need guarantee background board like this to get final product, and not need all faces all to be detected.Therefore open loop is made in the zone of corresponding detector field of view on the bracing frame, guarantee that bracing frame can not be detected, make background board in bracing frame, can rotate freely simultaneously, can solve existing issue.
The utility model is circular with the Cross section Design of supporting surface on the bracing frame, and the center line at place, the center of circle of bracing frame supporting surface overlaps with the rotation of background board simultaneously, has guaranteed that background board can rotate freely in bracing frame.Therefore the cross section of background board can be designed to regular polygon, in reality, can different background colors be set in polygonal different facial, realizes the target that a kind of light source just can the sorting various materials.
The utility model has the advantages that:
The utility model can be guaranteed the intensity of background board; Can victim way quantity, can not influence the precision of color separation and the reliability of color selector, and make simple, easy to use; Avoid existing weak point in the above-mentioned prior art; Fundamentally solve the inconsistent problem of major path color selector background signal, a kind of background adjusting device that can satisfy the major path color selector is provided, guaranteed machine performance.
