摘要:
A unit and method for forming a group of products on a wrapping machine, whereby a continuous supply conveyor feeds a succession of products to an input of a group-forming screw device; and a step-operated supply device, located at an output of the screw device, is controlled by a sensor for detecting the length of each group, to only feed complete groups to a wrapping unit of the wrapping machine.
摘要:
A method and unit for feeding products to a group-forming unit forming groups of products, each defined by a given number of products; an orderly succession of products is fed in a first direction by a first conveyor; the products are transferred from the first conveyor to a second conveyor by a first transfer device; an orderly succession of products is fed in a second direction by the second conveyor; the products are transferred from the second conveyor to a third conveyor by a second transfer device; an orderly succession of products is fed by the third conveyor in a third direction parallel to the second direction; and, when a vacancy is detected on the first transfer device, the second conveyor is stopped, and, at the same time, the second transfer device is moved towards the first transfer device in the opposite direction to the second direction.
摘要:
Tobacco products are wrapped by a unit equipped with a rotating drum carrying a set of holder mechanisms around the periphery, each rotatable about an axis parallel to the axis of the drum, by which single products are supported and carried through an assembly station together with leaves of wrapping material received from a vacuum roller turning on an axis parallel to the axis of the drum; the vacuum roller revolves tangentially to the drum at the assembly station and comprises a system by which each leaf is transferred to a gripper associated with the support mechanism. The transfer system is timed to operate in a situation of substantially zero relative peripheral velocity between the support mechanism and the vacuum roller.

摘要:
A method and unit for heat-shrinking overwrappings of heat-shrink plastic material of a succession of products; an orderly succession of products is conveyed by conveying means; each product is subjected to a first heat-shrink operation along the conveying means and by means of a first heat-shrink device; and each product is subjected to a second heat-shrink operation along the conveying means and by means of a second heat-shrink device separate and at a distance from the first heat-shrink device.
摘要:
A method and unit for applying a label to an article, whereby a supporting head is fed by a conveyor along a labelling path; the label is fed to a first seat of the supporting head; the article is fed to a second seat of the supporting head; and a relative movement is produced between the first seat and the second seat of the supporting head to apply the label to the article.

摘要:
A method of making a brand change, on an automatic production system for processing tobacco articles and which produces a first product from first materials; the method has the steps of: stopping the automatic production system once production of the first product is completed; feeding second materials onto the automatic production system; restarting the automatic production system to commence production of a second product from the second materials; checking all the second products in a first lot to ensure each second product in the first lot conforms with production specifications; externally marking each second product in the first lot conforming with production specifications; and generating a pass signal when a given number of consecutive second products conforming with production specifications is produced.
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.
