Abstract:
A device is provided for assembling article groups from layers of rod-shaped articles used in the tobacco-processing industry. The rod-shaped articles are stacked one above the other and side-by-side in group forming bins that are intermittently movable in a forward direction. A number of funnels are provided that correspond, respectively, to the number of the article layers. Each funnel is divided into chutes. The chutes of each funnel receive the rod-shaped articles at chute inlets and are arranged for dropping the rod-shaped articles to chute outlets to form a layer of parallel aligned rod-shaped articles. A platform is disposed at each chute outlet for receiving the respective layer of parallel aligned rod-shaped articles. The platforms are staggered at successively different heights to define respective layer planes. Transfer push-rods are associated with a respective one of the funnels and are movable in the axial direction of the rod-shaped articles for pushing a respective one of the layers into a group forming bin. Each transfer rod is disposed at a level corresponding to a height of the respective layer plane and has an elongated slot. A phantom article is arranged at one of the chute outlets of each funnel that corresponds to a placement of the elongated slot in a respective one of the transfer push rods. Each phantom article is displaceable crosswise to the axial direction of the rod-shaped articles in the respective layer.
Abstract:
Blocks of plain or filter cigarettes are accumulated in at least two group building assemblies each of which comprises at least two block forming units receiving cigarettes by gravity flow by way of upright ducts. The assemblies are adjacent the path of a series of successive receptacles which serve to transport discrete blocks stepwise to a multiple-track packing machine. The units accumulate blocks of cigarettes during intervals which include the duration of at least one stepwise movement of the receptacles and that of at least one period of standstill of the receptacles. Such intervals suffice to ensure satisfactory gathering of cigarettes into blocks of required size and shape at a frequency which is required for full-speed operation of the multiple-track packing machine.
Abstract:
A method and unit for transferring articles between a first seat in a given position, and a second seat traveling along a first path, whereby at least one pickup member for picking up the articles is fed along a second path extending between the first seat and the first path; the articles are transferred between the second seat and the pickup member at a point of tangency between the first path and the second path; and the articles are transferred between the first seat and the pickup member as the pickup member travels along a substantially straight portion of the second path, parallel to an input/output direction of the articles with respect to the first seat.
Abstract:
A system for delivering rows of cigarettes, each for forming one layer of a bundle of cigarettes to be packed in a packing machine, includes a number of fluted planetary wheels (42) carried by an annular carrier (44) along a path on which cigarettes are picked up directly from the lower ends of channels (40) formed between vanes (38) in the hopper of the machine. The wheels (42) transfer the cigarettes in rows to flute sets (48) on a coaxial drum (46) from which the rows are further transferred to a delivery drum (22). Generally the packing machine includes three such systems, one for each layer of the bundle of cigarettes to be packed. In an alternative system cigarettes forming one row are picked up substantially simultaneously by row carriers (220) mounted on planetary wheels (226) so as to follow an hypocycloidal path.
Abstract:
A system for inspecting the ends of cigarettes prior to their packaging on a conveyor line. The system provides telecamera units which produce images of the ends of a group of cigarettes. A processing unit then analyses the brightness level of a given area on each cigarette end. The processing unit then counts the total number of areas having a brightness level within a given range and compares that number with that of a reference end image for determining the existence of defects. An expulsion unit is further provided for rejecting those groups of cigarettes which fall below the requirements of the reference end image.
Abstract:
A diagnostic method for analysing the operation of an automatic machine which processes products in the tobacco industry includes the following steps: introducing into the machine an endoscopic probe whose shape and size correspond to the shape and size of the products the machine is designed to process and which the machine processes as if it were a real product. During processing in the machine, the probe acquires data through a sensor of its own. The method also includes determining the positions adopted by the probe while it is being processed in the machine and associating them with the data acquired by the probe while it is being processed in the machine.
Abstract:
The subject of the application is a device which supports mass flow of rod-shaped articles of the tobacco industry in a transport channel, having at least two segments (2, 3) connected by a connecting element (4), characterised in that the segments (2) are provided with positioning means (7, 8) which mate with the elements of the conveyor to set the position of the supporting device relative to the elements of the conveyor (5a, 5b). Furthermore, the subject of the application is a method of supporting mass flow of rod-shaped articles of the tobacco industry in a transport channel section characterised in that a supporting device (1) is introduced into the transport channel in the inlet part of the section being filled up provided with positioning means (7, 8) which with the elements of the conveyor set the position of the supporting device relative to the elements of the conveyor belt (5a, 5b), subsequently, the mass flow of rod-shaped articles is started in such a way so that the face of the mass flow is supported on the last segment of the supporting device, after which the travel of the belt of the conveyor in the remaining part of the section of the transport channel being filled up is started such that the mass flow of rod-shaped articles fills up the space of the channel section, supported on the last segment of the supporting device.
Abstract:
A method of feeding rod-shaped consumer goods to a packing apparatus is provided, including providing a plurality of rod-shaped consumer goods to an upstream end of a stacking channel, and feeding the plurality of rod-shaped consumer goods along the stacking channel to a downstream end of the stacking channel. The upstream end of the stacking channel is higher than the downstream end in the vertical direction, and at least a portion of the stacking channel extends at an angle of between about 25 degrees and about 75 degrees with respect to the vertical direction. The method further includes receiving the plurality of rod-shaped consumer goods into a hopper from the downstream end of the stacking channel, and distributing the plurality of rod-shaped consumer goods from the hopper into a packing apparatus.
Abstract:
A method of forming groups of cigarettes on a packing machine, whereby a conveyor feeds a succession of pockets in steps past a number of group-forming stations, where the pockets receive respective groups of cigarettes fed axially to the relative pockets by means of independent pushers, which are operated in a normal cyclic operating sequence to move selectively through respective group-forming stations; and whereby the formation of a gap along the conveyor, caused by non-supply of a faulty group to a relative pocket, is prevented by replacing the normal cyclic operating sequence with a different cyclic sequence capable of ensuring all the pockets are filled as of the fully operative group-forming stations only.
Abstract:
For the production of cigarette groups (11) having a formation comprising a plurality of vertical rows of cigarettes (10) arranged one beside the other, after pushing a corresponding number of cigarettes (10) out of shafts (13) of a cigarette magazine (12), a transverse displacement of the cigarettes (10) is required in order to arrange same in a tightly packed or saddle configuration. At least marginal push rods (18) for pushing the cigarettes (10) out of the shafts (13) of the cigarette magazine (12) can be displaced transversely together with the cigarettes.
