摘要:
The filling of a cigarette is controlled by detecting a brightness curve of at least one part of the open end of the cigarette, processing the resulting brightness curve to obtain a contrast index, and comparing the resulting contrast index with an equivalent index of a correctly filled cigarette to obtain a signal indicating acceptance of the cigarette under observation.

A pocket element for a packing wheel for packing groups of cigarettes in rigid packets with a hinged lid; each packet being formed by folding a precut blank; and the pocket element presenting a seat having a pair of locating elements, each having an oblique surface for supporting respective edges of a respective pair of end tabs of the blank defining a small longitudinal wall of the lid of a respective packet.
摘要:
A device for feeding cigarettes to a packeting machine. Cigarettes are placed in the lower part of a hopper in stacks mobile stepwise along respective outgoing channels from the hopper. A device is provided for checking the cigarettes descending stepwise along the channels, and another device which ejects faulty cigarettes is controlled by the checking device and includes, for each channel, a pneumatic extractor connectable to a suction source and a withdrawal element able to gain access to the respective channel to extract the faulty cigarettes from the interior of the hopper.
摘要:
The typical rigid cigarette packet consists of a box-like container with one open top end that can be exposed and closed by rotating a lid hinged to a rear edge of the container; the contents of the packet are restrained by a separate "U"-shaped frame element of which a first portion is anchored to the container and a second portion projects through the open top end and into the closed lid. To advantage, a front section of the first portion of the frame element incorporates a set of transverse stiffening ribs near the open top end of the container.
摘要:
A method and line for forming and conveying orderly groups of elongated products, particularly cigarettes, whereby each group is formed of a number of superimposed layers of products arranged side by side and separated by a given distance less than the width of the product and such as to compensate for the absence of at least one product in each of the layers each group being formed by feeding the relative layers axially and successively into a forming spindle, at least the bottom wall of which presents seats separated by the aforementioned given distance and for receiving and transversely retaining in position the products in a first layer; and each pair of adjacent products in one layer defining a seat for transversely retaining in position a product in an upper layer.
摘要:
A device for removing, from a reel of strip material, an adhesive tape secured to a peripheral surface portion of the reel via thermoplastic adhesive material; which device comprises a pair of rollers supporting the reel; one of the rollers being a drive roller for rotating the reel about its axis; at least one heating element located close to the peripheral surface of the reel and designed to substantially contact the tape; and the other roller having vacuum openings for removing the tape from the peripheral surface of the reel subsequent to the adhesive material being plasticized by the heating element.
摘要:
A pneumatic unit for supplying products, such as chocolates or similar, in a single line to a manufacturing machine along a route defined laterally by two walls and at the bottom by a plate through which are formed a number of nozzles for a pressurized pneumatic fluid; the nozzles being arranged in at least two rows symmetrical with the route; and each nozzle in each row being so designed as to emit a jet of pneumatic fluid, at least a first portion of which is directed in a traveling direction towards the manufacturing machine, and a second portion of which is directed transversely in relation to the traveling direction and towards the other row of nozzles.
摘要:
A distributing device for feeding flat products, i.e. flat slab-shaped products, such as biscuits or lozenges, to a user machine having two input channels, each designed to receive a respective stream of products; the distributing device presenting a single input channel, and featuring two lobed wheels tangent to each other and to one end of the input channel; each lobe presenting a cavity cooperating with a pickup and release device for retaining, inside respective cavities, alternate products traveling along the feed channel, and releasing said products onto a respective conveyor by which they are fed to a respective input channel of the user machine.
摘要:
A method of feeding and folding sheet material on a flip-top cigarette packing machine, whereby a wrapping wheel on the wrapping line of the packing machine is connected to a supply device whereby flat portions of sheet material, from which to form internal collars and, if necessary, coupons, are fed successively to the wrapping wheel and into contact with the outer surface of respective groups of cigarettes already present on the wheel; the collars being formed by folding the flat portions of sheet material about respective groups as these are transferred to a further wrapping wheel on the wrapping line.
摘要:
A method of replacing a first strip having equally-spaced preprinted graphics with a second identical strip on a manufacturing machine having an input traction unit for feeding the first strip along a first route defined by a first and second branch forming a given angle; the second strip, after being accelerated along the first branch and adjusted in relation to the first strip, being cut and fed on to the second branch by a spoon-shaped guide plate operating in a direction substantially coincident with that of the second branch.
