| 摘要 | The invention provides a machine which extracts artichokes oneby-one from a hopper, and conveys them individually on a conveyor device including grooved rollers, which rollers align the artichokes so that their axes are horizontal. Artichokes with their stems pointing in the wrong direction are manually or automatically reversed. Pincer arms remove the artichokes one-byone from the conveyor at the end of its travel, and convey them to clamps on a wheel, where cutters are employed to trim the artichokes, whereafter they are released by the clamps to drop into a hopper. Both the conveyor and wheel movements are intermittent and synchronised. | ||||||
| 权利要求 | 1. An artichoke treating machine including a hopper supplying artichokes to a feeding device, and a former following said feeding device, said former comprising first automatic means taking artichokes from said feeding device and second automatic means adapted to position said artichokes within said former, said feeding device comprising a conveyor belt having rollers each shaped like a grooved pulley and with an annular channel in the centre of said groove, means for driving said belt with an intermittent forward motion including at least one chain deriving its motion from at least one gearwheel meshing with the links of said chain, means for rotating said rollers during the passage along a horizontal portion of the path of said conveyor belt during said intermittent advancing periods of said belt, said former including an artichoke gripping device including pincers with gripping jaws, a cam and an opposing spring actuating the arms of said jaws; means aligning the free ends of said jaws coaxially with positioning device; and a positioning device including two cups supported by arms sliding in sleeves, and lever mechanisms actuating said arms for taking an artichoke from the jaws of said pincers and transferring to further jaws gripping said artichoke on said former. 2. An artichoke machine as recited in claim 1, wherein said means for rotating said rollers along a part of said horizontal path of said conveyor belt include an endless belt which drives the rollers by friction between said rollers and the material of said belt, and means for continuously driving said belt in a direction opposite that of the forward movement of said conveyor belt. 3. An artichoke machine as recited in claim 2, wherein said conveyor belt is associated with a lifting device and a correcting device for wrongly positioned artichokes. 4. An artichoke machine as recited in claim 3, wherein said device correcting the positioning of said artichokes includes a pincer which grips, raises and rotates an artichoke through 180*, and then returns said artichoke to its seat in the correct position. 5. An artichoke machine as recited in claim 1, wherein said devices engaging and positioning said artichoke effect all their movements during the intermittent period in the advance of said conveyor belt. 6. An artichoke machine as recited in claim 1 including means providing an intermittent advance motion having periods coincident with those of said conveyor belt. |
