| 摘要 | This invention relates to an apparatus for preparing the receptacles and fruits of bractated plants, more particularly artichoke bottoms, comprising a support for the receptacle; a blowing head for removing the leaves and the choke from the receptacle; sucker means for picking up the receptacle bottom from the support after such bottom has been cleaned by the blowing head; and machining means for removing irregularities in the shape of the bottom caused by removal of the leaves. | ||||||
| 权利要求 | 1. An apparatus for preparing the receptacles and fruits of bractated plants, more particularly artichoke bottoms, comprising a support for the receptacle, a blowing head including nozzles directed at the bracts for removing the leaves and the choke from the receptacle, sucker means for picking up the receptacle bottom from the support after such bottom has been cleaned by the blowing head, and machining means for removing irregularities in the shape of the bottom caused by removal of the leaves. 2. An apparatus as set forth in claim 1, wherein the receptacle support is a tubular member for receiving the receptacle stem. 3. An apparatus as set forth in claim 1, wherein the blowing head is adapted to rotate around its axis. 4. An apparatus as set forth in claim 1, wherein the blowing head has multiple nozzles. 5. An apparatus as set forth in claim 4, wherein the blowing head has two rows of nozzles disposed in a central part thereof, the nozzles of one of said rows extending axially and the nozzles of the other row extending inclinedly, the blowing head also having a pair of side arms. 6. An apparatus as set forth in claim 5, wherein the side arms have nozzles whose ends extend radially in one case and tangentially in the other. 7. An apparatus as set forth in claim 1, wherein the blowing head is mounted on an arm which also bears a support for the sucker means. 8. An apparatus as set forth in claim 7, wherein the sucker means support is pivotally mounted on the arm so as to be able to bring the sucker means either within the operative range of the receptacle support, to pick up the receptacle bottom therein, or into engagement with a mechanism for rotating the sucker means around itself to enable the receptacle bottom to be machined. 9. An apparatus as set forth in claim 8, including movable abutments which are adapted to locate the receptacle bottom when the same is being picked up by the sucker means. 10. An apparatus as set forth in claim 8, wherein the mechanism for rotating the sucker means around itself is mounted on the arm and has a shaft which is also used to rotate the blowing head around itself. 11. An apparatus as set forth in claim 1, wherein the machining means comprises a blade whose operative position is determined by a feeler contacting the receptacle bottom. 12. An apparatus as set forth in claim 11, wherein the feeler is adapted to move a template or cam or the like serving as a guide for the blade. 13. An apparatus as set forth in claim 11, wherein the blade is rotatable. 14. An apparatus as set forth in claim 13, wherein the blade is rotatable around a spindle borne by a support compelled to move along a template or cam which the feeler moves. 15. An apparatus as set forth in claim 1, wherein the machining means comprises a blade in the form of a domed member rotatable about its axis, and including a support member for the receptacle adapted to rotate around itself and to oscillate around an axis perpendicular to the axis of the domed member, to bring the receptacte within range of the blade. 16. An apparatus as set forth in claim 15, wherein the support member is mounted on a spider coaxial of the blade, the support member being movable by a cam on which the support member can roll as the spider rotates. 17. An apparatus as set forth in claim 1, including a bedplate having a central column receiving a rotating system supporting a working unit comprising the receptacle support, the sucker means and the machining means, said rotating system also supporting members for controlling the operations of said receptacle support, sucker means and machining means. 18. An apparatus as set forth in claim 17, wherein the receptacle support is supported by the rotating system by means of a parallelogram linkage which compels such support to move parallel to itself, said apparatus also including linkage cooperating with a cam mounted on the bedplate for moving the parallelogram linkage. 19. An apparatus as set forth in claim 18, including further linkage cooperating with another cam mounted on the bedplate to control operation of the machining means. 20. An apparatus as set forth in claim 17, including a knife for severing the stem from the receptacle flush with the receptacle support. 21. An apparatus as set forth in claim 17, wherein the movement of the rotating system and the movements of the blowing head and of the sucker means are derived from a central motor mounted on the column. 22. An apparatus as set forth in claim 17, wherein the column is hollow and serves for the supply of pressure fluid to the blowing head and for connecting the sucker means to a source of negative pressure. 23. An apparatus as set forth in claim 17, including a plurality of such working units supported by the rotating system symmetrically and in roundabout-fashion around the central column. |
