CONTINUOUS CYCLE MECHANICAL ARCHITECTURE ABLE TO SIMULTANEOUSLY BLOCK AND CUT LAYERS OF ANY NON-RIGID MATERIALS

Abstract: The present invention refers to a device apt to perform the continuous cutting of materials of any form and nature, provided they are stratified and not flexionally rigid. The device is essentially composed of: a fixed plane of slipping, having means for compression blocking placed after cutting means; mobile cutting means rigidly connected with further compression blocking means placed after said mobile cutting means; eccentric pushing means synchronized with blocking means both before and after said cutting means; a sliding guide. The above ensemble permits to cut non rigid, stratified materials, avoiding a dragging effect on such materials due to the cutting action.

Description: Description CONTINUOUS CYCLE MECHANICAL ARCHITECTURE ABLE TO SI¬ MULTANEOUSLY BLOCK AND CUT LAYERS OF ANY NON-RIGID MATERIALS The present invention refers to a mechanism which can 5. resolve the problems inherent in the cutting of non- rigid layered materials and, specifically, in those cases in which the cutting is dependent on a perfect blocking of the material itself, both before and after the cutting section. 10. In fact, for such types of materials, the cutting can be carried out only if the horizontal dragging due to the impact of the mobile cutting device on the mate¬ rial itself is prevented. The architecture i question, which uses suitable 15. blocking means to compress, and hence avoid the drag¬ ging due to the friction induced by the compression itself, resolves this problem. The main components of the architecture are shown in Fig.l. 20. The functional principle of the architecture is based on the following logical sequence: the advance of the material to be cut to the sup¬ port extremity 15; - the blocking both after and before the fixed 8 and 25. mobile 7 shears by means of the blocking units 21 and 12-13-14 respectively on the surfaces 9 and 15 of the mobile gathering plane 10; - the cutting of the blocked material by means of the vertical movement of the mobile shear 7 connected 30. to the mobile block constituted by elements 6-11- 16-18-20-13-14. Element 6 is controlled by an eccentric crank gear constituted by components 1-2-3-4-5. In addition, the structure 16 houses internally the 5. blocking means 12 linked to it by means of the pin 17. The movement of the entire mobile group is ensured by the special slipways 18 on the shoe 20 which constitutes the shoelink block part of the system; 10. - return of the eccentric crank gear to the "upper dead position" and resetting of the continuous plane 15 with the consequent realignment of all the components being prepared for cutting. This logical sequence can be automated to function 15. with a continuous cycle synchronised between its vari¬ ous elements. TYPOLOGY OF THE EQUIPMENT The architecture is mainly realised in metallic mate¬ rial and installed in a suitable robust and reliable 20. structure, which is also metallic, complete with all the accessories, alarms and safety devices. The description above does not indicate in detail the mechanism of the motor unit, as well as those of the ancillary functions, such as the guide, joints, trans- 25. mission, etc., since they are of no relevance and sec¬ ondary for the purposes of describing the functioning of the architecture which is the subject of the pre¬ sent invention. It is obvious that the invention is not limited to the 30. form of execution described and illustrated, but that numerous variations and further perfections can be made without prejudice to the framework of the inven¬ tion.
