The branch suction nozzle loosens abandonment iron sheet, the delivery suction nozzle slides left, observe one section abandonment iron sheet that rightmost end length is shorter after losing the absorption of branch suction nozzle, whether still scrape on the abandonment iron sheet of next station when hanging down naturally, if still scraping, adjust the height of absorbing unit 5 with the help of air spring 3, if do not have the scraping, then see whether can not scrape under the prerequisite of wiping next iron sheet, suitably adjust the height of absorbing unit 5, because highly lower, the stroke that lifts after the suction nozzle adsorbs can shorten, corresponding efficiency that delivers the material loading can uprise, adjust the back, remove two blocks of abandonment iron sheets, two iron sheet raw materials before changing, carry out the material loading.
The working principle is as follows: the gas spring 3 mainly comprises a piston rod, a piston, a sealing guide sleeve, a filler, a pressure cylinder, a joint and the like, wherein the pressure cylinder is a closed cavity, inert gas or oil-gas mixture is filled in the pressure cylinder, the pressure in the cavity is several times or dozens of times of the atmospheric pressure, the inert gas or the oil-gas mixture is filled in the closed pressure cylinder, the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and the movement of the piston rod is realized by utilizing the pressure difference generated by the fact that the cross section area of the piston rod is smaller than that of the piston.
The gas spring 3 comprises a free gas spring, a self-locking gas spring, a traction gas spring, a free gas stopping spring, a swivel chair gas spring, a gas pressure rod, a damper and the like. We use here a self-locking traction gas spring, which is a special gas spring, the other gas springs are all in the longest position when in a free state, i.e. move from the longest position to the shortest position after being subjected to an external force, and the free state of the traction gas spring is in the shortest position and runs from the shortest position to the longest position when being subjected to traction. The self-locking traction type gas spring can be stopped at any position in the stroke by virtue of some release mechanisms while keeping the characteristics of the traction type gas spring, and has a large locking force after the stop.
When the height is adjusted, 3 initial states of air spring are in the shortest position, because 3 lower extremes of air spring on this device are fixed, the upper end activity, so air spring 3 takes place to pull the back with the help of the less lift of workman, take place to pull, begin the extension, move from the shortest to the longest spontaneously, drive air spring linkage unit 4 and upwards remove, then indirectly drive and absorb unit 5 and rise, according to actual conditions and production needs, after rising to a certain position, in time the auto-lock, its locking force is great, it is stable to support fixed effect, if the adjusting position is too high, return air spring 3 to initial state, readjust can, whole process absorbs unit 5 and all is supported by air spring 3, need not the workman and carry and lift, very laborsaving.
The magnet in the magnet box 522 is composed of atoms such as iron, cobalt, and nickel, and the atoms have a specific internal structure and have a magnetic moment, and the magnet can generate a magnetic field and attract a ferromagnetic substance such as iron, nickel, and cobalt, so that the magnet box 522 has an automatic adsorption function on an approaching iron sheet.
The pulley rubber ring 533 has high elasticity with reversible deformation, and can support the iron sheet on the premise of ensuring that the surface of the iron sheet is not obviously scratched in the conveying process.
During delivery, the iron sheet is subjected to the suction force of the delivery suction nozzle and the magnet box 522 in the vertical direction, the delivery suction nozzle moves leftwards to drive the whole iron sheet to slide leftwards, friction generated by direct contact of the iron sheet and the magnet box 522 is eliminated by means of rolling of the pulley 532, namely, abrasion on the surface of the iron sheet is avoided, and the feeding speed is accelerated.
It should be noted that the present embodiment is only for explaining the present invention, and it is not a limitation of the present invention, and those skilled in the art can make modifications to the present embodiment as necessary without inventive contribution after reading the present specification, but all are protected by patent law within the scope of the claims of the present invention.
