摘要:
A method for transferring objects (2), wherein the objects (2) are fed in bulk in a loading region onto at least one first intermittently rotating disc (5; 6) of vertical axis, provided with a rim (9; 9') of holes (10; 10') for containing the objects (2); within a station (20; 20') there are provided members (21) which transfer the objects (2) from the holes (10; 10') of the first disc (5; 6) to the holes (18) of a second disc (15), and which engage each hole (10; 10') of the first disc (5; 6) once during every two revolutions of this latter.

In a method and device for continuously wrapping products (3), while the products (3) are being fed continuously at a first speed (V1) along an intermediate portion (44) of a first path (P1) and in a first direction (D1), together with their intermediate wrappers (2a), the latter having a first and a second wing (37, 38), projection from, and on opposite sides of a surface (30) of the product (3), the wings (37, 38) make contact with a first folder (43) that moves at a second speed (V2) which is faster than the first speed (V1) in a second direction (D2) coinciding with the first speed (D1) along a section (45) of a second a path (P2). The section (45) substantially coincides with the intermediate portion (44) of the first path (P1), so as to enable the first folder (43) to fold the first wing (37) towards the surface (30) of the product (3) and the second wing (38) away from the surface (30) until the second wing is in a position such that it extends from the surface (30) in the same plane, and where a gumming device (64) gums a portion of the wing (38), after which a second folder (65) folds the second wing (38) back towards the surface (30) so that its gummed portion comes into contact with the first wing (37)
摘要:
The invention relates to a method and device for continuously wrapping products, according to which, during the continuous feed of the products and respective intermediate wrappers which have four flaps to be folded, projecting in such a way that they are offset from the lower surface of the product, along a path with an instantaneous tangent extending in a first direction which may vary from point to point on the path, two opposite flaps make contact with respective first and second folding tools, located on opposite sides of an intermediate folding portion of the path. During their movement along respective closed paths, the first and second folding tools are subject to a first movement in a second direction transversal to the first direction, a second movement in the first direction, and a third movement, consisting of an oscillation about a relative longitudinal axis, so that each folding tool pursues and folds each flap, whilst remaining parallel with the instantaneous tangent and, therefore, with the surface of each product.

Flat articles to be formed into groups for packaging are advanced in succession at a set tempo toward a transfer station where each article is made to assume a predetermined position in space, standing on edge. Thereafter, the articles are advanced in a direction perpendicular to the position in space and toward a release station by means of a first conveyor equipped with pockets. The articles are caused to advance at a first linear velocity in such a way that each pocket receives an article and, at predetermined intervals, are accelerated to a second velocity for a predetermined duration between the arrival of one article at the transfer station and the arrival of the next article. In this way, one or more pockets remain empty, and groups of articles forming on the conveyor are separated one from the next by the empty pockets.

A storage unit for elongated elements, particularly cigarettes, wherein a mass of cigarettes is supported on a first conveyor movable both ways through a loading-unloading station where the first conveyor is connected to a second conveyor by a connecting plate; the first conveyor being defined by a helical conveyor belt presenting at least two longitudinal grooves defining, on the conveyor belt, at least two longitudinal bands, each presenting a respective succession of projections; and the connecting plate presenting a comb-shaped free end connected to the longitudinal grooves of the first conveyor.
摘要:
A system for producing and packing tobacco items, particularly cigarettes, wherein two packing machines are supplied with items by at least as many production machines, and wherein the outputs of the production machines are connected to one another by a conveyor channel for conveying the items and from which extend input channels connecting the conveyor channel to the individual packing machines; the items being fed along the conveyor channel by means of reversible conveyors.
摘要:
A method of producing cartons of cigarettes, whereby groups of packets of cigarettes are formed wherein the packets are arranged in at least two side by side stacks, and wherein each packet in each stack is laid flat with its longer axis horizontal and aligned with the longer axis of a corresponding packet in the other stack; and each group is fed, crosswise to the longer axes of the packets and together with a flat blank from which to form a rigid hinged-lid wrapping, into a folding spindle, the bottom wall of which supports the group with the interposition of a panel of the blank corresponding to a lateral wall of the rigid wrapping.
