Abstract
An apparatus (10) for the assembly of lamellar packs for electrical use in electric motor machines, generators, transformers, counters, ignition coils and similar electrical equipment by gluing, comprising a die-cutting station (12) for die-cutting a sheet (15) to define strips (15′) to be superimposed one on the other to define a lamellar pack and a station (14) for gluing—by means of glue—said strips (15′) sheared from said sheet (15) and comprising means for the discrete application of an amount of glue on a surface of the sheet (15) and with said means operating synchronously with the advancement of the sheet (15) in the die-cutting station (12).
Claims10
An apparatus (10) for assembly of lamellar packs for electrical use in electric motor machines, generators, transformers, counters, ignition coils and electrical equipment with gluing means, comprising:
- a die-cutting station (12) for die-cutting a sheet (15) to define strips (15′) to be superimposed one on an other for forming a lamellar pack;
- and
- a gluing station (14) for gluing by means of glue said strips (15′) cut from said sheet (15) and wherein the gluing station comprises means for discretely applying an amount of glue on an upper surface of the sheet (15) comprising a movable element (16) translating according to a lowering/lifting vertical direction with respect to the sheet (15) for a displacement of at least one gluing unit (18, 19) stabilised on said movable element (16) and provided with gluing means comprising a plurality of pins (20) suitable to pick up the amount of glue in the form of drops (25) from at least one gluing reservoir (22, 24) of the gluing station (14) containing the amount of glue (23), with said at least one gluing unit (18, 19) being translatable forward/backward according to a horizontal plane in a direction perpendicular to an advancement direction of the sheet (15) in the die-cutting station (12), a displacement of the movable element (16) and the displacement of the at least one gluing unit being synchronous with an advancement movement of the sheet (15) in the die-cutting station (12), operations of picking up the glue and depositing the glue on the strips occurring without interruptions in a working cycle with the lowering/lifting translation movement of the at least one gluing unit (18, 19) toward the at least one gluing reservoir (22, 24) corresponding to a simultaneous and synchronous lowering/lifting translation movement of another gluing unit displaced toward the sheet (15) for depositing the drops (25) thereon.
