摘要:
In an automatic machine for processing tobacco articles, and having a supporting frame having a vertical front wall, at which are located a number of operating devices located along a production line for processing a succession of articles, an inner first casing is provided which can be opened and covers at least some of the operating devices, and an outer second casing is provided which can be opened, is independent of the inner first casing, and covers at least part of the inner first casing in the form of a shell; the outer second casing has a front panel facing the vertical front wall of the frame and movable, with respect to the frame, between a closed or bottom limit position, in which the front panel contacts the floor supporting the frame and is separated from the inner first casing by a distance defining the depth of a soundproofing air chamber, and an open or top limit position, in which the front panel exposes and permits access to the vertical front wall of the frame and the inner first casing.

A method and device for turning over stacks of products on a cartoning machine, whereby a group of products, arranged in at least one stack, is fed into a container, from which the group is expelled by a push device after the container is rotated 90° about an axis from a loading position to a turned-over unloading position; the container has a first and a second passage enabling the push device to move through the container when the container is in the turned-over unloading position and the loading position respectively.

A method and unit for transversely cutting cigarette portions or similar on a filter assembly machine, whereby a cigarette portion is fed transversely through a cutting station to intercept a rotary circular blade, which is maintained in a work position by an arm mounted to oscillate about an axis parallel to the axis of rotation of the circular blade, so as to move the circular blade between the work position, a store for worn circular blades, and a store for new circular blades.
摘要:
A method and unit for flexing a flat blank having preformed fold lines; the flat blank is fed by a seat on a conveyor along a path through a flexing station, where a rigid folding body is rolled over the seat to fold the blank against two fixed folding spindles of the seat and about the preformed fold lines; and, on leaving the flexing station, the blank is allowed to spring back to its flat shape.

A method and unit for controlling a variable-capacity store, which has a first conveyor in the form of an endless belt having a conveying branch and a return branch of respective lengths variable in complementary manner, and a first and second actuating device; the conveying branch is connected to a second conveyor at an input station, and to a third conveyor at an output station; the first actuating device is controlled solely as a function of the status of the second conveyor, and the second actuating device is controlled as a function of the status of the third conveyor and as a function of the status of the first actuating device; the status of the first actuating device, the status of the second actuating device, and the status of the third conveyor are determined by respective encoders; and the second actuating device is feedback position controlled by means of a control unit to which the encoders are connected.
摘要:
A variable-capacity store having an endless belt conveyor, in turn having a conveying branch and a return branch; an adjusting assembly for adjusting the lengths of the conveying branch and the return branch in complementary manner; and at least one actuating device for transmitting a force to the belt conveyor to move the belt conveyor, and having a limiting device for limiting the maximum value of the force transmitted to the belt conveyor using a maximum threshold value established as a function of the fill level of the store.
摘要:
A storage unit, wherein a store receives a succession of substantially parallelepiped-shaped products from an input conveying unit at an input and in a given feed direction, and releases a succession of rows of products to an output conveying unit at an output separate from the input; the store having a conveying device, which extends through the input and the output, has a number of elongated pockets for receiving respective rows of products, and moves in a direction crosswise to the pockets to move the pockets from the input to the output along a path portion of variable length extending about at least one pulley having an axis of rotation parallel to the pockets and to the feed direction and movable transversely to vary the length of the path portion between the input and the output.
摘要:
A method and unit for changing the configuration of an automatic machine, whereby a user selects a desired end configuration by means of a selection device, and a display device then displays an orderly list of all and only the operations to be performed on the machine to convert the machine from a current start configuration to the desired end configuration; the list is arranged according to the sequence in which the operations are performed, and for each operation are displayed the state of at least one respective operating value in the start configuration, and the state of the same operating value in the end configuration.
摘要:
A method and unit for forming groups of products, whereby an orderly first succession of products is fed to an input of a conveying path along which a screw conveyor, rotating continuously about a respective axis and having a given number of variable-pitch threads, converts the first succession into an orderly second succession of groups as the products are fed along the conveying path.
摘要:
A unit for conveying products and having a main conveying device; two secondary conveying devices for feeding respective streams of products to the main conveying device via respective inputs; and a distributing device for so controlling the two streams that the products in a first of the two streams, on reaching an output of the main conveying device, are offset with respect to the products in a second of the two streams, so as to form a single succession of products through the output.
