Specific embodiment
Design process of the invention is sketched in conjunction with specific attached drawing 1-6:
Vibrating bunker 21 of the invention is in shape wide at the top and narrow at the bottom, open, below narrow most position can only accommodate 1 15 grams~40
Gram cray is placed longitudinally, and exit lower surface has at least two cray length lower surfaces to be parallel to the horizontal plane, vibrating bunker
Below 21 ends discharge port be can be by blanking cylinder 25 and baffle by the rectangular aperture of a cray size, opening
B24 control folding.Vertical rotating turret 41 shares eight magazines 43 and is fixed in horizontal rod 42, corresponds to eight stations, along work
Circle of position disk 6 is counterclockwise respectively upper material position, is adjusted and the position that discharges water, detection station, discharge station A, discharge station B, blanking
Station C, station, water filling station are resetted.It is provided with eccentric vibrating motor A on magazine 43, can be used as vibration source and magazine 43 is driven to vibrate,
The baffle A44 with 43 grafting of magazine is equipped with below magazine 43, baffle A44 can be by draining cylinder 8, the control movement of reset cylinder 9, gear
Plate A44, which is equipped with, exports rectangular aperture of the same size with magazine 43.Vision inspection apparatus 3 is by industrial camera, camera lens and transmission
Cable composition, is fixed on right above detection station.Negative pressure pressing device 5 is by exhaust fan 51, conduit 52 53 groups of negative pressure air port
At 52 one end of conduit connects exhaust fan 51, and one end is fixed below the detection station blanking port of station disc 6；On station disc 6
Discharge station A, discharge station B, the lower section discharge station C are provided with and export blanking port 61 of the same size, blanking port with magazine 43
61 lower sections are provided with baffle C62 by hinge, and baffle C62 controls its folding by steering engine 10.It the adjustment of station disc 6 and discharges water
It is provided with netted rectangular opening below position, detection station, it is in the same size with the outlet of magazine 43, it is effluent functions and negative pressure function.
Specific implementation process is as follows:
Vertical rotating turret 41 rotates under the drive of driving motor 7 in stepping, and each rotational angle is a station, vibration
Cray slides to below hopper under effect of vibration in hopper 21, and since hopper outlet position can only accommodate single cray,
Cray is in longitudinal arrangement in hopper outlet position.When there is magazine 43 to go to feeding station, 21 lower section baffle B24 of vibrating bunker
Open position is under the driving of blanking cylinder 25, cray falls into the magazine 43 that water filling station completes water filling in longitudinal.Material
Box 43 is up big and down small, and it is placed longitudinally that lower section can only accommodate cray, and magazine 43 in cray after being fallen into vibrating bunker 21
Holding is vibrated to adjustment and the position that discharges water discharges water completion, and the cray for falling into magazine 43 is upward if not back, then can be in water
It completes to turn by displacement, 43 inner wall smooth of vibrating bunker 21 and magazine.Continue to turn to adjustment and the position that discharges water, in this position
Push 43 lower section baffle A44 of magazine to the position that discharges water by draining cylinder 8, with water level decreasing, cray also stablizes at back upwards
43 bottom of magazine is fallen into, while magazine 43 stops vibration, and continues to go to detection station, while negative pressure pressing device 5 works, and leads to
Crossing negative pressure makes cray thorax abdomen be close to station disc 6, reduces detection error, after completing detection, determines large, medium and small and by vision
Detection device 3 issue signal control three blanking stations 10 closing device of steering engine make it is therein some be in open position, waiting
The current cray for completing detection and magazine 43 realize blanking after running to this position, and control steering engine 10 makes its closure after blanking.
Reset station is proceeded to, the baffle A44 of magazine 43 is controlled to off-position by gas reset cylinder 9.Proceed to water filling station
It completes magazine 43 to fill the water, so far completes a circulation.
Technological means disclosed in present aspect scheme is not limited only to technological means disclosed in above embodiment, further includes
Technical solution consisting of any combination of the above technical features.It should be pointed out that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
