The side surface of the first fixed way 311 is connected with an L-shaped auxiliary fixed way 325, the inside of the auxiliary fixed way 325, which is closer to the first fixed way 311, is provided with a top rod 320, the inside of the other end of the auxiliary fixed way 325 is provided with a bottom rod 318 and a first spring 319, the insides of the bottom rod 318 and the top rod 320 are hollow, the outside of the first spring 319 is connected with the bottom rod 318, the insides of the bottom rod 318 and the top rod 320 are provided with one-way valves, after the materials are adsorbed, the piston rod 310 and the limit ring 309 can be clamped, the connecting rope 313 can be in a tightened state because the piston rod 310 is positioned at the upper end, and when the adsorption of the materials needs to be cancelled, the device can move downwards;
when the device normally cancels the adsorption and places the material: as the bottom rod 318 of the device contacts with the tray first, the tray pushes the bottom rod 318 to retract into the auxiliary fixing channel 325 along with the movement of the device, and the air in the bottom rod 318 and the top rod 320 can not circulate, so that the air pressure in the auxiliary fixing channel 325 is increased to push the top rod 320 to move, when the top rod 320 moves, the connecting rope 313 is pushed to move, because the connecting rope 313 is in a tightening state at the moment, a downward pulling force is generated on the fixing rod 312 and the piston rod 310, so that the piston rod 310 moves downward and is not clamped with the limit ring 309, and the piston rod 310 is not fixed, so that the external air returns to push the piston rod 310 to move downward, the air pressure in the air chamber 307 is recovered to be normal and not adsorbing the material, and the fixing rod 312 also moves when the piston rod 310 moves downward, because the connecting rope 313 seals the lower end outlet of the first fixing channel 311, therefore, as the air pressure in the first fixed way 311 increases, the check valve in the top rod 320 is opened, so that air enters the inside of the top rod 320, meanwhile, the air can provide a pushing force for the top rod 320 to restore the original position of the top rod 320, and then the air can enter the inside of the secondary fixed way 325;
when there is material in the tray: because the material has certain thickness, so gag lever post 317 can earlier with the interior material contact of tray, and gag lever post 317's bottom is provided with induction system to make the device stop the downstream, avoid the material to take place to damage, the while device internal fixation's material also can normally downstream, thereby avoided the problem of windrow.
The working principle of the invention is as follows:
when adsorbing the material: the sucker 323 is attached to the material through the moving mechanism 2, when pressure is applied to the sucker 323, the second spring 324 contracts, so that the position of the sucker 323 is adjusted, the sucker 323 is attached to the material, then the air suction structure sucks out air in the air chamber 307, the piston rod 310 moves upwards, when the piston rod 310 moves to the top end, the upper end of the air chamber 307 and the air pressure in the air inlet frame 302 are reduced, the pressure limiting valve is opened, external air flows into the exhaust pipe 306 to drive the fixing frame 304 to rotate, the position of the sucker 323 is adjusted, and the next material is conveniently adsorbed;
when placing the material: moving mechanism 2 drives the material and removes to fixed position, then along with the removal sill bar 318 of device can with the tray contact, thereby make sill bar 318 enter into the inside of vice fixed way 325, atmospheric pressure increase in the vice fixed way 325 promotes ejector pin 320 and removes, ejector pin 320 promotes to connect rope 313 and removes and make spacing ring 309 and piston rod 310 not at the block, thereby make external gas promote piston rod 310 and remove the recovery normal position, can promote dead lever 312 and remove when piston rod 310 removes, thereby make the gas in first fixed way 311 and the vice fixed way 325 spout from sill bar 318, thereby cushion the tray, cushion the material simultaneously, avoid the material to take place to damage.
