  • the activating unit 16 is of a type known in itself and substantially identical to the radial activating means of the jaws 107 of the mandrels 7, as for example of the type marketed by the company Rhom with the trade name TYP 538.
  • the sliders 116 have inclined surfaces 216 that co-operate with a conjugate conical axial pusher 316, the motion of which is driven in one direction by an hydraulic or pneumatic plunger 416 and by a contrasting spring 516 in the other direction.

Furthermore, the cores-gripping jaws 515 are arranged inside a recess 317 made on the radially internal side of the full bobbin 2 presence sensor ring 17.
  • each jaw 115 of the pick-up head 15 has a sensor 50 to detect the corresponding section of the external peripheral edge of the bobbin in the position ready for being picked-up from the bobbins-carrying storage 11.
  • the sensors 50 can be of any type and are formed preferably by photocells with a preset field of reading in the axial direction of the bobbin 2 that is superior to a preset axial distance from the face of said bobbin 2 in position of pick-up turned towards the pick-up head 15 from jaws 115 and inferior to the corresponding distance from the opposite face, with reference to a associated preset reading position of the pick-up head 15 itself.
  • the reading position of the pick-up head can be any position comprised between the one of maximum distance away from the bobbin 11 in the pick-up position and the one of readiness for pick-up, that is of maximum nearness.
  • the sensors 50 can be provided also on the gripping jaws of the cores gripping clamp.
  • a control box 51 controls the motors or the actuators of the storage 11 of the horizontal saddle 12 and of the vertical one 14 of the pick-up head with the jaws to clamp the bobbins 2 and the jaws to grip the cores 102. Furthermore the control box drive actuators of the said jaws and in the case the sensors 50 should be provided for on the jaws of the cores-gripping clamp also the motors and the actuators of the conveyors 5.
  • the box receives the signal of the sensors 50.
  • the processing of the signals of the sensors 50 takes place in such a manner, whereby the motors and the motion actuators, that is of horizontal and vertical transfer of the pick-up head 15 and of movement of the bobbin 2 or of the stack of bobbins 2 in the horizontal plane of the storage 11, as well as the transfer and motion of the conveyors 5, are activated, in order to obtain a signal of presence from all the sensors 50 that read the bobbin 2 or the core 102.
  • the bobbin 2 and/or the core 102 and the pick-up head 15 result to be axially perfectly aligned , within the range of the accepted tolerances.
  • the direction is obviously indicated by the sensor or sensors 50 that do not read the presence of the associated part of the bobbin or of the core.
  • the criteria of movement can be of any type and can be managed in a manner as to optimize the handling.
  • the path R of supply A of the bobbin 2 or of the stack of bobbins 2 is anular, preferably circular, in the horizontal plane.
  • control box 51 By suitably programming the control box 51, it is possible to generate geometric criteria of movement of the bobbin 2 and/or the core 102 and of the pick-up head 15 that minimize the centering procedure.
  • a circular path allows also to provide for a bobbin-carrier storage 11 of a rotating type that carries at least two stacks of bobbins.
  • the stacks of bobbins are distributed angularly with their axes on a same ideal circular path with reference to the axis of rotation of the storage 11. In the case of only two bobbins 2, these are obviously diametrically opposite each other.
  • the reading takes place in conditions of closure of the jaws 115 and/or 515 of the pick-up head 15. In this way it is possible to prevent errors due to tolerances of the diameter of the bobbins 2 and/or cores 102.
  • control box is programmed in such a way to stop the pick-up head 15 in the position of detection of the centering and to control the clamping jaws 115 of the bobbin 2 or those that grip the cores 102 in position of closure. Then the reading process of the centering is carried out and when the centering is completed, the jaws are opened and the pick-up head 15 is brought in clamping position of the bobbin 2 or the core 102.
  • the control box 51 keeps count of the number of bobbins 2 of each stack.
  • programming the parameters relative to the axial dimensions of the bobbins in the control box it is possible to adapt from time to time the vertical position of detection of the pick-up head 15, always taking the same to such a distance from the bobbin 2 on top of the stack, where the radius of operation of the sensors ends at an intermediate level between the two faces of said bobbin 2 on the top of the stack. This can be obtained both by raising the support plane of the bobbin-carrier storage 11, as well as more convenient for said construction by adapting the vertical position of detection of the pick-up head.
  • the control box 51 will be equipped for example with a counter and with a suitable data processing program in which the axial dimension of the bobbins can be programmed and that keeps score of the number of bobbins picked-up from each stack, as well as of the code of the stack itself.
  • the pick-up head 15 will therefore be approached from time to time in a dimension corresponding to the number of bobbins 2 picked-up from the corresponding stack as far as the vertical reading position of the centering is concerned., each time that the corresponding stack presents itself to the position of pick-up of a bobbin, that is in the pick-up station.
  • the reading position of the pick-up head 15 can be determined from the direct measurement by the pick-up head 15 of the level of the face turned towards the same of the bobbin 2 on the top of the stack in the pick-up station.
  • This option can be used in the case that stacks of bobbins should be used that are not homogeneous with regards to the axial dimensions within the range of a stack itself.
  • the sensors can also be arranged in different positions and this also dependent from their topology or it is possible to provide different types of sensors in different positions.
  • the movements of reciprocal alignment or centering of the bobbin and/or the core with the pick-up head can take place in both directions as indicated by the arrows F1 and F2 in Fig. 1 and can also be formed by steps of advancement of a preset amplitude. It is also possible that the steps are instead calculated for example thanks to additional information on the position of the bobbin and/or core and/or pick-up head.
  • these are constituted by tables in form of a plane rotating around a vertical axis. These carry more stacks of full bobbins 2, each of the stacks being taken to the pick-up position, coinciding coaxially with the pick-up head 15, with a preset rotation 111 of the plane of the table. This one is driven by a motor 211 by means of a suitable transmission (not illustrated) and in a synchronized manner with the means of supply, or with the pick -up head 15.
  • the rotary plane 111 of the storage in form of a rotating table is suitable to house or is formed by a so-called pallet, facilitating considerably the operations of loading the storage 11.
  • the pallet has dimensions different from the ones of the CEE standards and substantially reduced, that is the 1200 mm of length and 800 mm of width.
  • Each pallet can in this way house substantially diagonally offset two bobbins of diameter of 600 mm, like those customary used in the cigarette packing machines, or similar.
