Specific embodiment
As shown in Figure 1, 2, a kind of vacuum-ness detecting device of can described in the embodiment of the present invention, comprising: motor 2 passes through
Flange 3 connects turntable 1, and the edge of turntable 1 processes through-hole 4.Seat 5 is mounted on the inside above through-hole 4, by bolt and turns
Disk 1 is fixed above, and the inside of seat 5 is arc-shaped, and diameter is consistent with the diameter of can 14, when can be brought into from conveying it is logical
When at hole, play the role of limit.The height of seat 5 is less than the half of 14 height of can, facilitates subsequent striker plate gear can.
Lifting body 15 is mounted below through-hole 4, is connect by bolt with the bottom surface of turntable 1；Conveyer belt 13 is mounted on turntable 1
Outside, consistent with the radial direction of turntable 1, shelves item 12 is mounted on the two sides of conveyer belt 13, facilitates the charging of can.Radial photoelectricity
Detector 7 and tangential Photoelectric Detection head 8 are mounted on the upper surface of turntable 1, for detecting whether can tilts, while after signaling to
The cylinder in face.The curved block that block 6 is one section of arcuation is jacked, is mounted below through-hole 4.Striker plate 9 is mounted on the upper of turntable 1
Face；Cylinder 10 is guiding twin-tub rod-type, is connect by bolt with striker plate 9, is arrived the rejecting of underproof can using striker plate
Rejected product collection table.The outside of striker plate is installed by rejected product collection table 11.Discharge port 32 is in the outside of the turntable 1, side
To consistent with the tangential direction of turntable 1, facilitate the discharging of qualified can.
As shown in figure 3, processing the convex shoulder cooperation above groove 17, with cover 18 below through-hole 4, guarantees cover 18 and lead to
The concentricity in hole 4.The center line of cover 18 is overlapped with the center line of through-hole 4.Lifting body 15 include cover 18, cover 18 it is interior
Upper spring seat 19 is processed at hole, jacking axis 20 is mounted in cover 18, and the top of jacking axis 20 is connected through a screw thread jacking head 16,
Be convenient for changing jacking head, the middle part of jacking axis 20 processes lower spring cup, spring 21 be mounted on upper spring seat 19 and lower spring cup it
Between, the bottom of jacking axis 20 is the part 23 that climbs.The head for jacking head 16 is cone.Lid is bolted below cover 18
Son 22.Under normal circumstances, jacking head 16 is made to be in low level by the elastic force of spring, when lifting body reaches at jacking block, axis
It holds and is jacked up by jacking section, make to jack head in a high position, jack the bottom of the head contact can of head.
As shown in figure 4, the lower middle position processing groove of axis 20 is jacked, machining small at the two sides earrings of slot；Climb part
23 include small axis 24, and small axis 24 passes through aperture, and bearing 25 passes through small axis and is mounted in slot, and the two sides of bearing add retaining ring 26, small axis
The other end locked with locking nut 27, installation bearing makes static friction become rolling friction, keeps jacking steady.
As shown in figure 5, the upper surface of jacking block 6 is one section of cambered surface, including section 29 of climbing, jacking section 30 and downlink section 31, top
The front end processing guiding changeover portion 28 for rising block 6, is conducive to the transition of bearing.
Such as the lifting principle figure that Fig. 6-8 is can.
In conjunction with attached drawing, the principle of the present invention is illustrated, when can vacuumizes, certain vacuum is reached inside can
When spending, certain recess can occur for the bottom of can, as shown in fig. 6, jacking the cusp of the cone head of head at this time will not encounter
The bottom of can, but the bottom of can is encountered below cone, the bottom contact of can is that an astragal contacts at this time, and can is flat
It surely, will not run-off the straight.When vacuum degree inside can is not high, the bottom of can will not be recessed or deflection is smaller,
As shown in fig. 7, the cusp for jacking the cone head of head at this time encounters the bottom of can, the bottom contact of can connects at this time for a bit
Touching, can loses steadily, and run-off the straight (such as Fig. 8) is shown, by after subsequent Photoelectric Detection by unqualified can striker plate
It rejects.
Using the bottom of jacking crown can, when the recess of vacuum in canned product height, tank bottom is deep, jacking crown tank bottom will not be sent out
Raw inclination；When vacuum in canned product is low, the recess of tank bottom is shallow, and jacking crown tank bottom makes underproof can run-off the straight, due to tank
The slightly variation at bottom can make can that biggish inclination occur, and be easy detection.Turntable circles can as carrier, side
Just it detects, while rejecting simpler.The design of lifting body, simple and reliable, the screw thread for jacking head is flexibly connected, and is convenient for changing.
Cylinder cooperates photoelectricity movement, and striker plate is made to move up and down, and keeps the rejecting of useless bottle simple and easy, it is fast to reject speed.
When specifically used, for convenience of the present invention is understood, it is described in conjunction with attached drawing；
Conveyer belt conveys can in place, generates a thrust by can of the subsequent can to front, and turntable rotates,
When the position for processing through-hole on turntable reaches the import of conveyer belt, a Bottle & Can head is pressed against the upper surface of through-hole, and passes through seat
Positioning.Dial movement takes can at jacking block to, and bearing enters section of climbing, bearing by the changeover portion before jacking block
It is gradually raised, jacking head rises simultaneously, and when bearing reaches jacking section, bearing is in highest order, jacks the cone of head at this time
Head top to the bottom of roller, qualified can keep vertical, and underproof can run-off the straight utilizes radial Photoelectric Detection head
And tangential Photoelectric Detection head detects the gradient of can, determines whether can is qualified, when confirming unqualified, sends instructions simultaneously
It to subsequent cylinder, allows cylinder that striker plate is driven to move down, underproof can is rejected to rejected product collection table, it is qualified
Can next link is transported to by discharge port.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
