摘要:
Method for the packaging of articles with a plastic film which is based on the use of a packaging machine equipped with transverse welding devices arranged along a longitudinal direction where the method involves the steps of (a) positioning the articles on a conveyor belt with pushers activated by a motor; (b) distancing the articles from one another to provide a constant space or pitch; (c) feeding the plastic film, in the direction of the conveyor belt; (d) longitudinally welding the film in the direction articles on the conveyor belt; (e) activating the motor group situated downstream with respect to the welding device to weld and separate the film in the space between articles; and (f) activating the motor group of the welding device situated upstream with respect to another welding device to weld and separate the film in the space between the articles.

摘要:
An automatic feed device for individual publishing products of different thickness and sizes includes a first conveyor belt (13) and a second conveyor belt (14) arranged with the first conveyor belt (13) being partially over the second conveyor belt (14) in combination with an automatic feed device having a bearing structure (15), a pair of manipulator members (19) for gripping the publishing products (12) on the first conveyor belt (13). The publishing products are then laid down on the second conveyor belt (14) separate from one another while the manipulators (19) alternately move forwards and backwards between the first and second conveyor belt (13, 14) to transfer the individual publishing products to two predetermined positions on the first and second conveyor belts (13, 14).
摘要:
A turning device for graphic publishing products in a conveyor line and/or packaging machine that can be combined with a push conveyor (14) for the advancement of products (11), spaced out one after the other, including a supporting member (16) bearing in sequence a first conveyor unit (17) to pickup at least one of the products (11) off the conveyor line, a grasping and turnover unit (18) of at least one of the products (11), a second conveyor unit (19) to deposit at least one of the products (11), turned upside down on the conveyor line, the conveyor units (17, 19) being operated to advance in phase with the push conveyor (14) and being movable between a working position and a disengaged position with the conveyor line.
摘要:
For association with a packaging line, a device for overturning packaged editorial products which grips the editorial products (12) advancing on a conveyor belt (13) and overturns them to superpose them on the next product in order to facilitate their final stacking within a collection element. Such a device is particularly advantageous when handling packaged editorial products the thickness of which varies along their length by virtue of consisting of at least one editorial product (12') combined within its wrapper with a second added product (12") of different dimensions.
摘要:
An automatic apparatus for folding sheet elements fed one after the other in succession, comprising a first unit for U-shaping the sheet elements to define two vertical side portions and a longitudinal central region, a pusher element for V-shaping the central region and a second unit for the final compaction of the V-shaped sheet elements. The apparatus also comprises a third unit for rotating the folded compacted sheet elements leaving the second unit through 90.degree. and elements for separating the parallel side-by-side edges of the thus folded and compacted sheet elements to enable further additional elements to be inserted between them. The speed of the various units is correlated to prevent any deterioration or slippage of the sheet elements.
摘要:
An automatic machine for the packaging of a series of editorial products in plastic film comprising feeding means of editorial products (11, 11′) and a packaging station (20) equipped with a mechanical conformer (21) for the winding of the film (12) around the products (11, 11′) and means for the closing of the same, also comprising two pusher conveyors (14, 16) alongside each other for the feeding of a first product (11) and at least a second product (11′) respectively, to the packaging station (20), which comprises at least one longitudinal closing device (23) and a transversal welding station (25) for the formation of a packaging (100), the packaging (100) comprising two closed and separate bags (101) for the first product (11) and the second product (11′) respectively.
摘要:
A method for the packaging of editorial products (11) in plastic film comprising the phases of unwinding a plastic film (12) from a bobbin (13) and feeding it in a longitudinal direction (F), applying preprinted self-adhesive labels (16) to the film (12) transversally with respect to the longitudinal direction (F) and distanced between each other by a pre-established length greater than the length of the editorial products (11), positioning the editorial products (11) on the film (12) in the space between two subsequent labels (16), folding the plastic film (12) over the editorial products (11), welding the plastic film (12) longitudinally and transversally with a first transversal welding line (22) to form two containment areas (100a, 100b) of the label (16) and editorial product (11) respectively, and also with a second transversal welding line (23) forming a head of a finished packaging (100,100′) separated by means of the second transversal welding.
