Screened housing air blowing pay-off
Technical field
The utility model relates to a kind of screened housing pay-off, relates in particular to a kind of screened housing air blowing pay-off, belongs to field of mechanical technique.
Background technology
When screened housing detects, need screened housing be delivered to the detection position through pay-off.Because of screened housing thinner usually; Lighter weight, yielding, when using pay-offs such as common feeding belt conveyor, vibrating disc to transmit screened housing; Deformation very easily takes place because of factors such as vibrations in screened housing in transport process, influenced quality such as base planeness of screened housing etc.
The utility model content
The utility model technical matters to be solved provides a kind of screened housing air blowing pay-off, and it is steady to transmit screened housing, and the transport process continuity is good, efficient is high, and screened housing is had no adverse effects.
For solving the problems of the technologies described above; The utility model provides a kind of screened housing air blowing pay-off; It is characterized in that; Comprise that one is used to hold the long straight trough of screened housing, said straight trough side is provided with the valve of the air blowing of the screened housing in straight trough obliquely, and the terminal sidewall of said straight trough is provided with the sensing element that is used for induction sheath cover position.
Said straight trough comprises the initiating terminal of sending into screened housing and the end that takes out screened housing and gets material level.
Said valve tilts to blow towards the screened housing direction of transfer.
The air-flow oblique fire that said valve blows out is to the upper surface of screened housing.
Said valve is connected with the compressed air source unit that gas is provided through tracheae.
A plurality of said valves are set.
At said initiating terminal one said valve is set at least.
Said sensing element is arranged on said end and gets on the sidewall of straight trough of material level.
The end of said straight trough is got material level top and is provided with the pneumatic suction nozzle that can said screened housing be picked up.
Said sensing element is a sensor.
The beneficial effect that the utility model reached:
The screened housing air blowing pay-off of the utility model; Rely on the gas that valve blew to transmit screened housing; Transport process steadily, continuous property is good, efficient is high, and the external force that acts on screened housing is little, and screened housing can not produce distortion; Screened housing is had no adverse effects, guaranteed screened housing steady quality in the feeding process.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
Like Fig. 1, shown in Figure 2, the screened housing air blowing pay-off of the utility model comprises a platform 8, and long straight trough 1 that is used to hold screened housing 2 is set on the platform 8, and a plurality of screened housings 2 are sequentially arranged in the straight trough 1 by same direction.Straight trough 1 comprises initiating terminal 11 that gets into screened housing and the end 12 that takes out screened housing and gets material level.But the sidewall of straight trough terminal 12 is provided with the proximity transducer of getting material level 4 or other triggering elements that whether the induction sheath cover gets into straight trough terminal 12.
Straight trough 1 side is provided with the valve 3 of 2 upper surfaces of the screened housing in straight trough air blowing obliquely, and valve 3 is provided with towards the screened housing direction of transfer, and valve 3 is connected with the compressed air source unit that gas is provided through tracheae.The air-flow size that valve 3 is blown can be regulated as required.
It is initiating terminal 11 and approaching terminal 12 the position that is separately positioned on straight trough that valve 3 can be provided with a plurality of, preferable modes.Quality according to the screened housing that transmits in the length of straight trough 1 and the straight trough also can increase valve 3 quantity by other location-appropriates in straight trough.
The top of straight trough 1 can also be provided with the baffle plate 5 of barrier air diffusion.
The air-flow that is blown out by bevelled valve 3 acts on screened housing 2 upper surfaces in the straight trough, and this application force produces a tangential component to screened housing 2 direction of transfers at screened housing 2 upper surfaces, and it is mobile that more frivolous screened housing 2 is forwarded.Screened housing 21 foremost get into straight troughs terminal 12 get material level after, after sensor 4 is sensed this screened housing 21, will start pneumatic suction nozzle 6 and act on this screened housing 21 upper surfaces, this screened housing 21 is picked up and transmits, is positioned over detection position 7 carry out subsequent detection.After this screened housing 21 was taken away, under the effect of air-flow, the screened housing that is arranged in order moved forward continuing, and the material level of getting that straight trough is terminal is filled by next screened housing immediately, next screened housing get into again straight trough terminal get material level after, repeat said process.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection domain of the utility model.
