An apparatus (1) for wrapping products with plastic film (50) comprises: a ring-shaped element (3) supporting a carriage (4) that moves around the ring-shaped element (3); drive means (5) for moving the ring-shaped element (3) relative to the group (P) of products to be wrapped; main motor means (6) associated to the ring-shaped element (3) and designed to drive the carriage (4). The carriage (4) mounts a roll (7) of plastic film and a pre-stretching unit (8) driven by suitable drive means (9). The pre-stretching unit (8) comprises a pair of rollers (10) for pre-stretching the film and a transmission and control roller (12) that swings towards and away from the group (P) of products and is designed to start or stop film feed according to its position relative to the group (P) of products to be wrapped. The drive means (9) comprise a kinematic chain consisting of the main motor means (6) and a ring-shaped, continuous drive take-off track (13) for the pre-stretching unit (8) drive means (9) which comprise an engage/release unit (14) connected to and controlled by the transmission roller (12) and designed to transmit drive from the ring-shaped track (13) to the pair of pre-stretching rollers (10) according to the position of the transmission roller (12).
摘要:
An apparatus for wrapping groups (1) of products with plastic film comprising: a horizontal surface (3) for supporting the group (1) and feeding it in a direction (A), the surface (3) being divided into two portions (3a, 3b) positioned on opposite sides of a ring (4) equipped with means (5) for dispensing film (F) around the group (1) of products passing through the ring (4), and in such a way as to wrap the group (1) of products in a spiral and according to a predetermined direction (V); a film (F) gripping and cutting unit (6) designed to allow the formation of a wrapping tail end (C) for the group (1) of products; the unit (6) being positioned close to the ring (4) and at the portion (3a) of the surface (3) upstream of the ring (4) relative to the direction of feed (A), and wrapped by the film (F); means (7) for joining the film (F) acting on a section (T) of film (F) wrapped around the group (1) and positioned close to the gripping and cutting unit (6) so as to allow the section (T) of film (F) subsequently forming part of the tail end (C) to be joined to the coils (S) of film above, in this way stably sealing the wrapping on the group (1) of products.

摘要:
A machine for wrapping groups of products with plastic film comprises a unit (5) for feeding the film (2) consisting of a roll (6) and an idle roller (7) linked to the rotation of a ring (4) through a supporting arm (10) which is acted upon by means (11) designed to adjust its position relative to the surfaces (1a, 1b, 1c, 1d) of the group (1) of products to be wrapped and relative to the position assumed by the ring (4) when it rotates, in such a manner as to form a guide and to enable the film (2) to be unwound close to the surfaces (1a, 1b, 1c, 1d) independently of the shape and size of the group (1) of products being wrapped.
