Apparatus for moving and positioning objects to be press laminated
First Claim
1. An apparatus for moving and positioning objects to be laminated inside a press, comprising:
- a tray which is arranged on a substantially horizontal plane and in which multiple seats are provided which have a substantially vertical axis;
a plurality of pins, each of which is accommodated in a respective said seat and is provided with a head which protrudes, with an end thereof, from an upper face of said tray;
a supporting surface for a lower face of an object to be positioned in the press formed by the heads of said pins, said pins being actuatable to move individually along the axis of the corresponding seat in order to pass from a raised position, in which the pins make contact with and support the object, to a lowered position, in which the pins are spaced downwardly from the object;
elastic means being provided for each of said pins and cooperating with each corresponding pin and seat in order to retain said corresponding pin in said raised position, said elastic means being flexible in order to allow transition of said pin from the raised position to the lowered position and vice versa; and
selection means which are actuatable by being movable in a first translational direction to engage with a portion of each said pin which protrudes downwardly from said tray for actuating transition of said pin from said raised position to said lowered position, said selection means being further actuatable by being movable in a second translational direction opposite to said first translational direction to engage with said portion of said pin which protrudes downwardly from said tray for actuating transition of said pin from said lowered position to said raised position, said selection means being configured such that all of said plurality of pins are moved into said raised position when said selection means are moved in said second translational direction, and said selection means being configured such that only selected pins of said plurality of pins are moved into said lowered position from said raised position when said selection means are moved in said first translational direction.

Abstract
An apparatus for moving and positioning objects to be laminated inside a press, comprising a tray arranged on a horizontal plane and having multiple seats with vertical axis. Each seat accommodates a pin having a protruding head and forming, with their heads, a supporting surface for the object to be positioned in the press. The pins are movable along the seat axis to pass from a raised position, in contact with the object, to a lowered position, in which they are spaced downwardly from the object. The apparatus further comprises elastic wings which cooperate with each pin and seat in order to retain the pin in the raised position, and selection elements which can engage a protruding portion of each pin for the transition of the pin from the raised position to the lowered position.

5. An apparatus for moving and positioning objects to be laminated inside a press, comprising:
- a tray which is arranged on a substantially horizontal plane and in which multiple seats are provided which have a substantially vertical axis;
a plurality of pins, each of which is accommodated in a respective said seat and is provided with a head which protrudes, with an end thereof, from an upper face of said tray;
a supporting surface for a lower face of an object to be positioned in the press formed by the heads of said pins, said pins actuatable to move individually along the axis of the corresponding seat in order to pass from a raised position, in which the pins make contact with and support the object, to a lowered position, in which the pins are spaced downwardly from the object;
elastic means being provided for each of said pins and cooperating with each corresponding pin and seat in order to retain said corresponding pin in said raised position, said elastic means being flexible in order to allow transition of said pin from the raised position to lowered position and vice versa; and
selection means which are actuatable to engage with a portion of each said pin which protrudes downwardly from said tray for actuating transition of said pin from said raised position to said lowered position;each of said pins comprising;
a head which protrudes upwardly from the corresponding seat, a stem which has a reduced diameter with respect to said head and is accommodated so as to be slideable along the axis of the corresponding seat, and a foot of the pin which is pivoted to the stem of the pin about a horizontal pivoting axis and is rotatable about said pivoting axis with respect said stem of the pin, in order to vary a useful axial length of the pin, from an extended condition of the pin, in which the foot of the pin is aligned with the stem of the pin, to a shortened condition of the pin, in which the foot of the pin is rotated laterally to the stem of the pin, and vice versa;said foot of the pin, in the extended condition of the pin, with the pin in the raised position, being located so as to protrude downwardly, with a lower end thereof, from a lower base of said seat;
said selection means being actuatable to engage with said lower end of the foot of the pin which protrudes downwardly from the lower base of said seat in order to produce transition of said foot of the pin from said extended condition of the in to said shortened condition of the pin upon rotation thereof about said pivoting axis with respect to the stem of the pin, and said foot of the pin being adapted to interfere during said rotation thereof with said seat, for actuating the transition of the pin from the raised position to the lowered position;the apparatus comprising bushes, each of which having formed therein a said seat and being inserted in a through hole which has a substantially vertical axis and is formed in said tray, each said bush further protruding with a portion thereof below said tray, and wherein said portion of each bush having a lateral recess, starting from its lower end, which is adapted to allow rotation of said foot of the pin about said pivoting axis, starting from the extended condition of the pin in said raised position, in a single direction of rotation and wherein said recess further forms a lateral support for the foot of the pin, which is spaced downwardly from said pivoting axis of the foot of the pin in the raised position and in the extended condition of pin, during the rotation of the foot of the pin about said pivoting axis in the transition from the extended condition of the pin to the shortened condition of the pin, in order to produce the transition of the pin from the raised position to the lowered position; and said bush portion having said lateral recess on only a region thereof so as to comprise a non recessed area which contrasts the rotation of said foot about said pivoting axis in the opposite direction with respect to the direction of rotation allowed by said recess when said pin is in the extended condition and at least in the raised position or in a position which is intermediate between said raised position and said lowered position.
- a tray which is arranged on a substantially horizontal plane and in which multiple seats are provided which have a substantially vertical axis;
