When feeding, the supporting rod cylinder 133 drives the supporting rod 131 to move outwards to prevent the blocking electromagnet 121 from descending, the electromagnet 121 descends to the position of the uppermost pipe fitting 300 of the stacked pipe fittings 300 under the action of the electromagnet height adjusting mechanism to adsorb the uppermost pipe fitting 300 and is driven by the electromagnet height adjusting mechanism to ascend, then the supporting rod cylinder 133 drives the supporting rod 131 to move below the uppermost pipe fitting 300 adsorbed by the electromagnet 121, at the moment, the electromagnet 121 is powered off, and the uppermost pipe fitting 300 falls onto the supporting rod 131, so that a person skilled in the art can control the falling height of the uppermost pipe fitting 300 as required to ensure that the arrangement of the uppermost pipe fitting 300 cannot be damaged; then, the cylinder 1411 of the rodless cylinder 141 of the tube conveying mechanism 140 drives the pushing block 142 to push the uppermost tube 300 from one side, so that the uppermost tube 300 is entirely displaced, the tube 300 on the other side of the uppermost tube 300 is pushed to the first material grabbing and conveying mechanism 210 of the punching unit 100, the feeding is completed, and the uppermost tube 300 is continuously pushed until all the tubes 300 of the uppermost tube 300 are conveyed to the punching unit 200. Thereafter, the above process is repeated to transport all the tubes 300 of the stack of tubes 300 to the punching unit 200.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
