Definitions

  • the invention refers to an apparatus able to rotate "remote",that is, so to speak, from a distance, a member disposed at the end of the rod or the body of cylinder of a cylinder-piston system, that is, without making use of a means to rotate said member placed in the vicinity of said ends and fixed thereto.
  • the rod in an apparatus for rotating a member solid with and made to translate by the rod of body of a cylinder of a cylinder-piston system, the rod is connected to the piston in such a way as to be able to rotate idly relative thereto and the outer surface either of the rod or the body of cylinder is made prismatic (or slotted that is splined) and slides guided within a suitable prismatic (or slotted) seat formed inside a bush which can rotate, suitably supported, inside a stationary structure, coaxial with said system, said structure being solid with the frame to which the stationary part of the system is secured, and said bush being driven into rotation by a gear solid therewith or by equivalent means.
  • the member which must be rotated is solid with and made to transflate by the rod, the cylinder body being stationary, and the rod is connected with the piston through a set of thrust and guide bearings keyed on its end inside the cylinder and housed in suitable seats inside the piston, said stationary structure within which the bush rotates being substantially located on the extension of cylinder.
  • the rod has square cross-section, with more or less rounded corners.
  • the outline of the rod cross-­section may be a polygon with more than four sides, especially hexagonal.
  • the bush within which the rod slides is driven into rotation by a pinion keyed on the output shaft of a motor-reducer whose casing is solid with the body of the cylinder, said pinion meshing with a gear solid with the same bush.
  • the apparatus according to the model provides an easy and extremely simple solution of the problem of rotating a mobile bottom of a container or a plate for the pressing inside a press, or of rotating any other member, during a translation movement thereof obtained by means of a common cylinder-piston system, or even during the dwell of said mobile member at whatever position along the working run of the rod of said system.
  • Fig. 1 shows containers, indicated by 9 made up solely of cylindrical walls lacking in the bottom part, within which a respective dish or mobile bottom 20 is free to slide for the lifting and the lowering.
  • the container 9 on the right (in the drawing) is at a position in which it is filled, in successive layers, with coils of textile rove, coming from the machine 1 which delivers such rove continuously from a mouthpiece B, especially oscillating.
  • the dish 20, after a complete initial lift must be able to lower down of one step on each completed layer, while continuously rotating for the coils formation.
  • the lifting and the lowering are obtained by means of a cylinder-piston system 29; on the rod 27 of system 29 which a discoidal plate 30 is fixed which, upon its lifting, leans against the dish 20.
  • the dish 20 is friction-driven into rotation by the plate 30 that is caused to rotate by the rod 27 which is solid therewith.
  • the rod 27 is engaged with the piston 28 (Fig. 2) so as to idly rotate relative thereto, through a pair of guide and thrust ball bearings 22, 24, keyed on its lower end - whose diameter is relatively reduced - and housed in corresponding seats in a cavity 28C inside of and coaxial with the piston 28.
  • the outer surface of the rod 27 is characteristically of prismatic construction, (for example having square or hexagonal cross-section) or even slotted, so that the rod itself may slide within the hole 34, also of corresponding prismatic or slotted construction, of a sleeve 36 being relatively developed in height.
  • the sleeve 36 can rotate, supported by a pair of guide ball bearings 38 in the inside of a stationary hollow cylindrical member 42 which, through a lower flange 42F, is fixed to the cylindrical wall 29C of the cylinder-piston system 29 so as to form more or less an extension thereof (in the drawing).
  • a further upwardly displacement of the pressed material, placed between the dish 20 and the dish 49, is performed, until it reaches the binding position L, that is, with the upper and lower walls of said dishes respectively at the same level of the guides of a common binding machine 50 supported by the press framework.
  • the surfaces of both the dish 20 and the dish 49 are provided with slots, mostly diametral, (for example, three slots staggered of 120° one with respect to the other) for the passage of the element, usually ribbon-­like and of relatively solid construction (as a plastics strap) utilized for the bindings.
  • the arrangement is such as to have, upon the beginning of pressing, the channels of dish 20 and the corresponding ones of the dish 49 exactly superimposed, that is, with the respective center lines disposed on a vertical plane forming dihedrals for example of 120° with other similar planes; for each binding operation, the two dishes must be made to rotate through such an angle that the two channels belonging to the two dishes come to lie on the same vertical plane of the guides of the binder.
  • the plate 45 transmits its own motion of rotation to the dish 20 not by friction but with no possible slidings, by a joint made up of teeth or pins 48 apt to be precisily inserted into corresponding hollow seats formed in the lower surface of the dish 20.
  • the rotation of the plate 45 may be determined by such means, like a motor-reducer 43, whose lifting along with the same plate is prevented.
  • the plate 45 is fixed on top of rod 41A of the cylinder-piston system 41 which rod is thus solid therewith.
  • the outer surface of the rod 45 is prismatic, (or slotted), for the sliding of said rod pushed by piston 41P, within the correspondingly prismatic for slotted hole 34 ⁇ , of a sleeve 36 ⁇ restrained from moving upwards.
  • the sleeve 36 ⁇ may rotate, supported by a pair of ball bearings 38 ⁇ inside a fixed hollow cylindrical member 42 ⁇ which is secured, through a lower flange 42 ⁇ F so as to form almost the extension thereof, to the cylindrical wall 41C of the cylinder-piston system 41.
  • a gear 44 ⁇ is provided which can be driven into rotation by the pinion of the output shaft of the motor-reducer 43 fixed in lower position to the frame of press 3.
  • the prismatic (or slotted) rod 41A is able to rotate relative to the piston 41P, as it is rotatively secured thereto through a pair of guide and thrust ball bearings 22, 24, keyed on the lower end thereof, of relatively reduced diameter.
  • Said bearings are in turn housed in corresponding seats of a cylindrical cavity 41R inside of and coaxial with the piston 41P.
  • a pneumatic positioner member 57 is provided, fixed to a flange 59 projecting from the hub 55 being solid with the rod 47A.
  • the positioner member 57 comprises a cylinder-piston system 61 whose rod exhibits a truncated-cone end towards the dish 49, able to be inserted into suitable seats, also of truncated-­cone shape, circumferentially disposed on a disc 62, at angular distances equal to the angular displacements that the dish 49 has to perform with maximum accuracy.
  • the disc 62 is fixed above the dish 49 and is in parallelism relationship and solid therewith.
  • the positioner 57 is put into operation so that the truncated-cone end of the rod of system 61, by penetrating the seat of the disc 62 which has come into alignment therewith owing to the friction-operated rotation of plate 49, causes that small additional rotation in one direction or the other necessary for the channel for the binder of the dish 49 to become exactly superimposed to the corresponding channel of the dish 20.
  • the apparatus according to the model allows very significant simplifications: in fact it permits, with relatively simple, little expensive and of small dimensions means, the rod of said system to be rotated whatever its position may be, thereby achieving also the rotation of any member operated by the same rod and solid therewith. This avoids to be obliged to supply, according to the prior art, the end of the rod, for example, of a motor-reducer apt to rotate the rod-operated member which, again according to the prior art, used to result idle relative thereto.
  • the apparatus according to the model may result reversed, in the sense that the member driven into rotation by the cylinder-piston system may also be connected with and pushed by the cylinder which is mobile, the rod being instead stationary with respect to the machine frame.
  • the rod is always connected with the piston so as to rotate idly with respect thereto, but the wall of the cylinder body (which is the part of the system which moves relative to the rod) is instead made prismatic and said prismatic wall slides within a guide seat also prismatic, formed inside a bush like one of those indicated by 36 or 36 ⁇ .
  • Such bush can rotate supported by bearings like those indicated by 38 or 38 ⁇ inside a stationary member like 42 or 42 ⁇ , said member being coaxial with the cylinder-piston system and suitably secured to the same frame with respect to which the rod results stationary.
