Definitions
- the above invention eliminates these drawbacks at the same time offering important advantages as will be explained below.
- Subject of the invention is'an automatic loading means for rolls of paper or of other material for rotary printing ma ⁇ chines, impregnating systems for plastic laminates, packing machinery and other kinds that use such rolls.
- the loading apparatus comprises:
- a roll carrying carriage sliding along rails on the floor, supporting the roll parallel to said carriage's sliding axis ;
- the two motor-driven devices determine hoisting movement and action by two levers one of which locks and the other presses the transversal sides of the carriage, one on each side, locking it in its position of arrival on the table.
- the table can rotate fanwise, in relation to the translating means, around a vertical pin ' laced close to one of said table's transversal sides, rotated by a motor-driven de ⁇ vice which locks said table on the longitudinal axis of symmetry aligning its rails with those of the translating means .
- Said device orientates the axis of the roll placed on the carriage in line with the common geometrical axis of the roll-supporting mandrels on the roll-utilizing machine.
- the hoisting means translates vertically by devices moun ⁇ ted one close to one side and one close to the other, res- pectively facing one mandrel dnd the other referred to above.
- the devices respectively close to one or other of the above sides can synchronise their action for uniform translation of the hoisting means, or else can operate separately to obtain a position for the hoisting means such that the le- vels of the geometrical axis of the roll, on each side of said roll, respectively correspond to the levels of each of the mandrels referred to above.
- the detector system comprises two detector devices, sub ⁇ stantially the same, mounted as a pair in the positioning station, one on one side of the hoisting means and the other on the other side.
- Each device comprises a slide equipped with a sensor for determining the longitudinal position of the roll, said sen ⁇ sor automatically regulating movement of said slide until it reaches the previously fixed position in relation to said roll.
- Said sensors also control automatic action of the locking and pressing levers placed, on the table transpor ing, the carriage, one against each side of said carriage, until the sensors signal that the roll has been longitudinally centered in relation to the position of said detector devices and therefore in relation to the above mandrels.
- the detector devices comprise height sensors, one borne by one of the slides of said devices practically at the height of one of the above mandrels and consisting of a radiation emitter, the other sensor being borne by the other slide practically at the height of the other mandrel and consisting of a photoelectric cell or other type of recei ⁇ ving sensor.
- a stop order is automatically given to the hoisting means when the radiations passing through the tubular core of the roll reach the photoelectric cell confirming, that the geo ⁇ metrical axis of the roll is almost at the level of the above mandrels.
- a head On each slide of the above devices a head is mounted, said head moving longitudinally and horizontally and supporting a cone-shaped projection by means of a ball joint.
- Radial elastic means keep the geometrical axes of said cone-shaped projections reciprocally aligned with the geo ⁇ metrical axis between the mandrels of the roll-utilizing machine, the position of said projections being controlled by a group of radial sensors _
- said projec ⁇ tions assume a more or less angular position according to the position of the roll in relation to the axis of align- ment of said projections.
- the electronic control panel controls backward or forward move ⁇ ment of the translating means, rotation of the table Sup ⁇ porting the carriage around its fulcrum on the translating means and vertical movement of one or other side of the hoisting means until the position sensors signal that the geometrical axes of both cone-shaped projections coincide with the axis of the roll.
- the translating means further comprises a device for dis ⁇ charging the roll core remaining on the mandrels when the whole roll has been consumed.
- Said discharging device con ⁇ sists of a projecting body rotating around a horizontal motor-driven shaft and having an oblong seat parallel to said shaft . When rotating, said body can take up two positions: a dis- charging position with the seat for the roll core substan ⁇ tially horizontal and the other discharging position with the seat of said core substantially vertical.
- the following automa ⁇ tic cycle of operations is carried through.
- the roll having been placed on the carriage, standing at some point accessible to the loading means, said carriage is brought to the first loading station passing along the floor rails, along the translator rails and along those for the table as far as the central point of said table.
- the ⁇ ⁇ levers on the table for locking and pressing rise up and lock the carriage in position.
- the translating means moves towards the hoisting means, passing from the floor guides onto those of the hoisting means, carrying the roll to the positioning station.
- the hoisting means rises until stopped by the sensors for indicating level.
- the positioning sensors determine the correct position of the slides on the detector devices and the roll is then cen ⁇ tered longi udinally in relation to the cone-shaped projections and therefore in relation to the mandrels mounted on the roll-utilizing machine.
- the cone-shaped projections advance until aligned with roll orientation; the sensors on said projections adjust the geometrical axis of the roll to correspond with that of the mandrels and bring the roll into the correct position.
- the carriage then moves to the loading station and the roll is placed in line with the above mandrels.
- the mandrels approach the roll and take it up.
- the hoisting means descends and the translating means returns to the first loading station. As soon as the roll is exhausted the sequence of core un ⁇ loading movements commences at the conclusion of which the system is ready to start a fresh cycle.

- translating means (81) passes from base ( 10) (Fig.2) to the hoisting means (35) along guides (30).
- the translating means (81) has an oblong longitudinal cavi ⁇ ty ( 100) in which, along its axis (Figs. 2,5, 6) there is a recess ( 101 of trapezoidal cross section; on the edges of said cavity, at each of the four corners is mounted a ball bearing ( 102) on which rests the table ( 105) of a trapezoi ⁇ dal cross section with horizontal extensions ( 106), ( 107).
- a ball bearing 102 on which rests the table ( 105) of a trapezoi ⁇ dal cross section with horizontal extensions ( 106), ( 107).
- bushing ( 110) Figs. 3, 5
- said table ( 105) can swing around the vertical pin ( 111) fixed to the translating means (81) and placed at one end of said table's longitudinal axis .
- the translating means (81) houses a device ( 145) composed of a shaft ( 146) to which, at one end, is fixed the lever (147) with adjustable head ( 148) and, at the other end, an arm (149) connected to an electric motor ( 154) by a threaded ring nut (150), revolving on the end of said arm and in which a threaded shaft (151) rotates, said shaft being in turn con ⁇ nected to the shaft of said motor by a rotating joint (152).
- a second device (159) substantially the same as the first de- vice (145), comprises a shaft (160), electric motor (161) and lever (162) with a head (163).
- the rails (170) and (171) of the translating means (81) are substantially the same as rail (130) to which they are aligned one on each side of the table (105).
- the translating means (81) supports a device (123) (Figs. 4, 6) for discharg ⁇ ing the core (201) of the roll (200) when said roll is exhaus- ted.
- Said discharging device consists of a body fixed to, and pro ⁇ jecting out, from a shaft (125) revolving on the sides (122) of the translating means (81). At the summit of said body there is a channel ( 124) made for housing the cores (201) of the rolls.
- a toothed arch (126) is splined onto one end of the shaft(125), said arch meshing with pinion (127) which the electric motor ( 129) rotates through the ratiomotor ( 128).
- Shaft ( 125) and channel ( 124) are parallel one to another and perpendicular to the direction of movement of the trans ⁇ lating means (81). Therefore when said translating means takes up its position at the roll-bearing arms (26) of the machine' ( 27) , said channel ( 124) will lie parallel to the roll core (201) and beneath it.
- Each of these detector devices comprises a base ( 182) on which guides ( 183 are mounted made from a cylindrical bar, over which move the bushings ( 185) fixed to the slide ( 184). Supports ( 186) for the threaded rod ( 187) are rotated by an electric motor ( 188) and are fixed to the above base.
- a threaded bushing, mounted on said threaded rod ( 187) is sup ⁇ ported by a bracket ( 190) fixed to the slide ( 184).
- Said slide comprises parallel horizontal guides ( 191) made from cylindrical bars, along which move the bushings ( 192) fixed to the head ( 193) of the detecting device concerned.
- Slide (184) supports, on a bracket (207), articulation (202) of fluidic cylinder (203) for movement of piston (204) se ⁇ cured to articulation (205) of bracket (206) fixed to the head (193) by bushing ( 192).
- said head ( 193) supports the de ⁇ tecting cone (212) for roll (200) with its tubular core(201).
- Said cone is fixed to a rod (213) articulated, in relation to the coupling (211), by a ball joint (214).
- An adjustable balancing weight (215) is mounted on th ⁇ back end of said rod.
- a spherical collar (216) is mounted between said weight and ball joint (214), said collar carrying radial pressure devices (220) each comprising a compression spring (221) and a piston (222) supported by a sliding structure (223).

- the detector device ( 181 ) substantially the same as device (180), includes the detecting cone (195), head (196) and electronic limit switch (197).
- the rays of light ( 198) (Fig.7) from inside said detector cone (195) reach the photoelectric cell (233) through the tubular core (201) of the roll (200).
- a signal goes to motors ( 188) (Fig.3) which translate the slides ( 184) fitted with sensors (240) and ( 197).
- sensors (240) and ( 197) As soon as said sensors meet said roll, they signal the slides to stop forward movement and if one is too far forward it is made to move back.
- ac- tuate motors (154) and (161) (Fig. ) which, by means of arms (147) and (162), move the carriage (16) until it is correct ⁇ ly centered.
- the fluidic cylinders (203) (Fig.7) then begin to function and move the cone-shaped projections (121) and (195) until they touch the core (201) of the roll (200* ).
- the cone-shaped projections are subject to action by pressing means (220) (Figs. 7, 10); when said projections are not active, said pressing means keep them elastically in a central position and therefore reciprocally aligned on an axis practically parallel to the axis common to the roll-bearing mandrels of arms (26) of the roll-utilizing machine (27) (Fig.2).
- the electronic sensors (231) and (232) (Figs. 7, 9) ascer ⁇ tain if the cones are at an angle in relation to the correct central position, any such angle being due to imperfect ho- - rizontal or vertical alignment of the roll's axis in rela ⁇ tion to alignment between the cones (212) and (195).
- the electronic control panel actuates motor (90) (Fig.
- connection with motor (60) is cut off by detachment of joint (74) and connection between shafts (64) and 65) is cut off by detachment of joint (75) (Fig.1).
- Adequate luminous signals not illustrated in the figures, light up when the roll has reached its correct position.
- Translating means (81) then moves in the direction of arms (26) on the main machine (27) (Figs. 1, 2) and into posi- tion (81") where the hoisting means (35) takes the roll (200) to position (200").
- the control panel releases levers ( 147) and ( 162) locking the carriage (16)' (Fig.4), and the mandrels move out from the roll-bearing arms and close into the core (201") of the roll.
- Motor (60) (Fig. l) lowers the hoisting means (35), motor (90) starts up and returns the translating means (81) to its initial resting position shown in Fig.1.
- Motor (129) (Fig.4) raises the discharging means ( 123) to position (123') (Fig.2).
- Motor (90) moves the translating means (81) back to arms (26) on the main machine (27) in position (81").
