摘要:
Strip material used in packaging machines is fed by a rotary support unit carrying a roll of a first or a second strip material, installed downstream of a feed unit supplying a first wrapping material along a first direction toward an operating station where inner wrappers are fashioned for the particular packet in production. The first strip material is decoiled by rollers and guided along the first direction to an operating station where coupons are prepared for inclusion as inserts, placed between the inner and outer wrappers of each packet. The second strip material is taken up and diverted by further rollers along a second direction, such that it is supplied to a cellophaner where it is cut and folded to fashion leaflets applied as onserts to the outer wrapper of each packet before being overwrapped.

A method and device for feeding sheets to a user machine, whereby the sheets, arranged in a stack along a channel having a substantially horizontal longitudinal axis, are fed to a single-sheet pickup member by dividing the stack into an output portion, an intermediate portion, and an input portion; pushing the output portion towards the pickup member at a given constant first pressure; compressing the input portion at a given second pressure; transferring sheets from the intermediate portion to the output portion to compensate for the withdrawn sheets and keep a length of the output portion substantially constant and equal to a given value; and transferring sheets from the input portion to the intermediate portion to keep the density of the sheets along the intermediate portion substantially constant and equal to a given value.

摘要:
Wrapping material utilized by a packaging machine is advanced along a set feed path through a station where an accessory material, typically adhesive, is applied in spots to selected areas of the surface, whereupon the material is charged electrostatically at a first station, and thereafter sensed at a second station to reveal the distribution of the charges; the electrostatic charges register more strongly on and around the spots, so that by measuring any variation in strength relative to the remainder of the surface, identifiable with faulty application of the adhesive, substandard material can be detected before it reaches the wrapping stations of the machine.

A device (2) for feeding reels (3) has a manipulator (14) having a gripping member (19) for picking up one reel (3) at a time off a pallet (16) and transferring the reel (3) to an unwinding pin (4a; 4b) on a machine (1); the gripping member (19) is enabled to pick up a reel (3) off the pallet (16) when at least one reference point (k1) of the gripping member (19) lies inside a central hole (7) of the reel (3).
摘要:
A cutting unit for cutting blanks for collars of rigid cigarette packets, wherein a continuous strip of packing material is fed in a given direction through a cutting station equipped with a knife having an incision member and a blade, and with a fixed cutting block having a counterblade; the knife oscillates, about a fixed axis crosswise to the travelling direction of the strip, to and from a work position in which the incision member cooperates with a contact surface of the cutting block to incise a portion of the strip upstream from the counterblade, and the blade is located beyond the counterblade to cut the strip along a cutting line.
摘要:
A method and unit for applying labels to products fed by a conveyor along a conveying path; a number of pickup heads are fed along a feed path to withdraw the labels successively from a feeder and apply the labels successively to respective products on the conveyor; and, in the event of stoppage or malfunctioning, the pickup heads are fed along a reject path, adjacent to the feed path, to transfer at least some of the labels on the pickup heads to a collecting device.
摘要:
A turn-around device for packets, in particular packets of cigarettes, wherein the packets are fed successively, with a first surface facing forwards, to a turn-around station, from which they are extracted, with a second surface facing forwards, by a gripper conveyor, which travels through the turn-around station perpendicularly to the second surface, and has a number of grippers, each of which defines a pocket for a relative packet, and closes gradually onto the packet to control its position as it is extracted from the turn-around station with the second surface facing forwards.
摘要:
Groups of cigarettes approaching a packer are transferred and inspected by a conveyor equipped with receptacles advancing along a set path, and an inspection device such as will verify the presence and the integrity of each cigarette in each receptacle and generate signals to indicate the outcome of the inspection. The conveyor also incorporates emitters in the form of permanent magnets, each associated with a relative receptacle and interacting with a receiver consisting in an array of magnetoresistors ordered along the conveying path; the receiver is capable of emitting signals synchronized with the steps of the inspection procedure and indicating the position of each receptacle relative to a fixed inspection position.

An embossing device having a first embossing unit for satin finishing a strip of packing material, and a second embossing unit for impressing graphics on the strip of packing material; the second embossing unit has two embossing rollers, at least one of which only has embossing pins in areas for impressing the graphics.
