A rigid package, particularly for cigarettes, substantially in the form of a rectangular prism and defined by a cup-shaped body having, at the open end, a collar and a lid hinged to the rear edge of the cup-shaped body; the package being formed from a blank incorporating the collar, and wherein a central panel with lateral tabs defines the front wall of the package, and presents, together with the tabs, a precut line for detaching the front edge and lateral edges of the lid from corresponding edges of the cup-shaped body.

In a packaging machine supplied continuously with strip material fed forward by means of pinch rolls and trimmed at a cutting station, the leading end of a new strip is overlapped with the trailing end of the depleted strip at the moment of effecting a changeover; the two strips are separated, before entering the cut, by a device comprising a pair of feelers stationed between the pinch rolls and the cutting station, and capable of movement at least between an at-rest position in which the feelers remain outside the dimensional compass of the strip material, and an operating position in which the feelers are moved substantially into alignment with the leading end of the new strip in such a way as to slip beneath and detach it from the trailing end of the depleted strip.

A method and device for bending the end tabs of blanks for producing rigid flip-top cigarette packets. The blanks are loaded on a conveyor and are fed continuously along a path with the end tabs slidably engaged in a helical slit, which is in part defined by facing helical surfaces of first and second helical guide elements. The blanks wind over an arc of 180.degree. for bending the end tabs in a U and enabling the bent end tabs to be fed between two pressure rollers of a stabilizing unit.

A device for changing reels of strip material on a production machine, whereby a traction device unwinds a first strip off a runout reel on a supporting spindle and feeds it to the production machine along a given path; a standby reel is supported on edge on a saddle defined by two rollers; and a swing arm supports a powered disk with suction cups and a locating spindle. As the first strip runs out, the standby reel is made integral with the disk by the suction cups; the disk is accelerated so as to wind a second strip, identical to the first, off the standby reel and through a guide device by which the second strip is inserted into the traction device; and the swing arm loads the standby reel on to the axially-sliding supporting spindle in place of the empty reel.

Products fed by a first conveyor at substantially constant speed along a first substantially circular path and inside respective first seats are transferred successively into respective second seats on a second conveyor by which each second seat is advanced at a speed equal to that of the first conveyor along a second path tangent to the first path; which transfer is effected by a pusher and a counterpusher cooperating respectively with the first and second conveyors, and moving both parallel and perpendicular to the respective path;the pusher moving, during transfer, both parallel and perpendicular to the second path and in time with the counterpusher.
摘要:
A method and device for feeding and changing reels on a manufacturing machine, whereby reels of strip material arranged side by side are fed successively into a first operating position substantially coplanar to a second operating positionwherein the strip material is unwound normally. Each reel is supported in the second position by an arm which, as the reel in the second position runs out, releases the core of the empty reel, and picks up the reel in the first position; which reel has already been rotated, in the first position, by an unwinding device designed to feed the strip material on the reelin the first position at the same speed as the strip material on the reel in the second position.

A machine for packing cigarettes in rigid flip-top packs, wherein flat blanks are fed on to a wrapping wheel and each folded about a respective preformed group of cigarettes for forming a pack having gummed mating portions; and wherein the formed packs are transferred from the wrapping wheel to the bottom end of a first substantially vertical branch of a loop conveyor, and fed upwards to an unloading station at the top end of the first branch of the conveyor, where they are fed into a stabilizing and drying conduit extending over the packing machine and about a heating device consisting of at least one lubricating oil tank on the machine.
摘要:
A sensing facility that is integrated into a station from which strip material is fed to a wrap station, and/or into the roll and shaft from which the strip is effectively uncoiled, is designed to monitor an electrical impedance generated by the roll and shaft and/or linked to their overall radial dimensions. An output signal is triggered when the monitored level of impedance matches a selected reference value.
摘要:
A device for removing adhesive tape from a reel of strip material, comprising a base and two horizontal rollers for supporting the reel with one of the rollers adapted to drive the reel in a direction opposite to the direction the strip material is wound on to the reel; and a mechanism for rolling up the tape including a curved, oscillating wall connected to a linear actuator for bringing the curved wall into contact with a peripheral portion of the reel, the curved wall designed to engage by friction one edge of the tape for rolling up the same.
摘要:
In a device of the type used to supply a wrapping machine, typically with chocolates, conveyed singly and in succession along a belt, any chocolate incorrectly positioned on the belt is rejected by a device including at least one pair of disks rotating tangential to the belt about a shaft that lies transversely to the conveying direction. The two disks combine to create a calibrated passage through which correctly positioned chocolates pass without obstruction, whereas any wrongly positioned chocolate is gripped between the disks and rotated clear of the belt into a reject channel.
