摘要:
There is described a gluing unit (100) comprising a glue roller (101) for applying an adhesive pattern to labels being fed to a gluing station; a stationary adhesive distributor bar (102) adapted to dispense adhesive on the lateral surface of the glue roller (101); an adhesive scraper (109) for removing the excess adhesive and smoothing the surface of the adhesive applied on the lateral surface; and a support structure (116) for supporting the stationary adhesive distributor bar (102) and the adhesive scraper (109) in operative coupling with the glue roller (101); the rotation axis of glue roller (101) substantially identifies (see Figure 4 ), with stationary adhesive distributor bar (102), a symmetry plan (S) of the support structure (116); the support structure (116) defining at least two seats (117a, 117b) arranged symmetrically with respect to the symmetry plan (S) and adapted to receive and support the adhesive scraper (109), so that the gluing unit (100) can be assembled in either right-hand or left-hand configuration.
摘要:
There is disclosed a container processing machine (1) comprising a material handling surface (3)" for handling a sheet -like material through suction and a vacuum source (2) in fluid connection with said material handling surface (3), the machine (1) comprising: - means (17) for detecting and transmitting a value of pressure of the gas being suctioned; - a controllably operable flow valve (19); - a control unit (20) operatively connected with said detection and transmission means (17) and with said flow valve (19); said detection and transmission means (17) and said flow valve (19) being arranged between said vacuum source (2) and said material handling surface (3); said control unit (20) being programmed to adjust the degree of opening of said flow valve (19) in response to a signal which is a function of at least said value of pressure.
摘要:
There is described a labelling machine (1) for applying labels (10) onto articles (11), comprising a protective wall (4); one first labelling group (2; 3) which may- move between an operative position in which it applies a plurality of labels (10) onto corresponding articles (11), and a rest position; wall (4) comprises at least one first opening (15; 16) which is at least partially engaged, in use, by first labelling group (2) when it is set in operative position; first labelling group (2) is arranged completely on a first side of wall (4) as it is arranged in rest position, and is arranged at least partially on a second side, opposite to first side, of wall (4) when it is arranged in operative position; wall (4) comprises at least one first panel (17; 18) which may be moved between a closed position in which it covers opening (15; 16), and an open position in which it leaves free opening (15; 16); labelling machine (1) comprises connecting means (45; 46) for connecting first panel (17; 18) to first labelling group (2; 3) at least when first labelling group (2; 3) moves, in use, between rest position and an intermediate position, which is arranged between operative and rest positions; the movement of first labelling group (2; 3) between intermediate position and rest position causing, in use, the movement of first panel (17; 18) between open and closed position.
摘要:
There is described a machine (1) for applying labels on articles (3) transferred by respective labelling units (15) along a given path (P); each unit (15) comprises a receiving member (22) having a lateral wall (23), which is adapted to receive a relative label (2) and extends along an axis (F) transversal to the path (P); a cam and tappet device (24) axially displaces the receiving members (22) between a lowered position and a raised position and comprises a cam device (51), which is adjustable between a first and a second configuration; in the first configuration, cam followers of the units (15) move along a first track (R) of the cam device (51) to displace the respective receiving members (22) between the lowered and raised position during transfer of the respective units (15); in the second configuration, the cam followers (52) move along a second track (Q) of the cam device (51) to maintain the respective receiving members (22) in the lowered position during movement of the units (15) along their path (P).
摘要:
There is described a machine (1) for carrying out at least one operation onto a first article (11, 11a; 11, 11b) and a second article (11, 11b; 11, 11a) respectively, comprising: feeding means (150; 3) for advancing a succession of first article (11, 11a; 11, 11b) and second article (11, 11b; 11, 11a) along a path (P) and with a first speed (V0); a first operative group (4; 5), which comprises, in turn, a first tool (13) configured for carrying out operation onto first article (11, 11a; 11, 11b) and which can be operated with a second speed (V1) associated to first speed (V0); characterized by comprising gap creating means (110; 111, 112) selectively controllable to create a first gap (82), which is arranged inside succession and is bounded between a first article (11, 11a; 11, 11b) and a second article (11, 11b; 11, 11a); and a second operative group (5; 4), which comprises, in turn, a second tool (13) configured for carrying out operation onto second article (11b, 11; 11a, 11) and which can be operated at second speed (V1).
