Abstract
Abstract The magazine for parallel cigarettes in a packing machine has several groups of ducts each of which serves to accumulate successive layers of cigarettes at different levels so that the layer which is formed in the first group is disposed at a level below the layer formed in the second group, and so forth. A conveyor advances stepwise along the groups of ducts and has openended receptacles for layers which are transferred from the groups of ducts during each period of dwell of the conveyor by an intermittently actuated transfer unit. The conveyor is flanked by two stationary guide members whose undersides have sections disposed at different levels and staggered with reference to one another, as considered at right angles to the direction of travel of the conveyor. The guide members further have end faces against which the ends of cigarettes abut during travel from a preceding toward the next-following group of ducts. The sections of the undersides of the guide members overlie the respective end portions of the cigarettes during travel of corresponding receptacles between successive groups of ducts and while the receptacles are held in positions of register with such groups. The sections of the undersides of the guide members prevent the cigarettes in the lower layer or layers from shifting their positions owing to abrupt acceleration during the initial stage of movement from a preceding to the next-following group as well as owing to abrupt deceleration preparatory to movement into register with the next-following group of ducts. The fully assembled arrays of cigarettes in filled receptacles are converted into parallelepiped blocks at a station which follows the last group of ducts.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
232 words
Apparatus for assembling multi-layer arrays of parallel cigarettes or analogous rod-shaped articles, comprising a magazine having groups of ducts including first and second groups respectively arranged to successively accumulate first and second layers of parallel articles at a lower first and a higher second level; a conveyor having a plurality of receptacles arranged to move in a predetermined direction along said groups and being spaced apart from one another so as to register with said first and thereupon with said second group during successive intervals of dwell of said conveyor; means for transferring layers from said groups, lengthwise of the articles and at right angles to said direction, into the registering receptacles during the intervals of dwell of said conveyor so that portions of the layers extend from the respective receptacles and the second layers come to rest on the first layers in the respective receptacles; and guide means for said layers, including a guide member having an underside comprising sections disposed at different levels so that a first section overlies portions of articles in the first layers, at least during transport from said first to said second group, and that a second section overlies portions of articles of the second layers at least while the respective receptacles are in register with said second group, said sections being staggered with reference to one another as considered at right angles to said direction.
Claim 2
Dependent Claim
232 words
Apparatus for assembling multi-layer arrays of parallel cigarettes or analogous rod-shaped articles, comprising a magazine having groups of ducts including first and second groups respectively arranged to successively accumulate first and second layers of parallel articles at a lower first and a higher second level; a conveyor having a plurality of receptacles arranged to move in a predetermined direction along said groups and being spaced apart from one another so as to register with said first and thereupon with said second group during successive intervals of dwell of said conveyor; means for transferring layers from said groups, lengthwise of the articles and at right angles to said direction, into the registering receptacles during the intervals of dwell of said conveyor so that portions of the layers extend from the respective receptacles and the second layers come to rest on the first layers in the respective receptacles; and guide means for said layers, including a guide member having an underside comprising sections disposed at different levels so that a first section overlies portions of articles in the first layers, at least during transport from said first to said second group, and that a second section overlies portions of articles of the second layers at least while the respective receptacles are in register with said second group, said sections being staggered with reference to one another as considered at right angles to said direction.
Claim 3
Dependent Claim
11 words
The apparatus of claim 1, wherein said guide member is stationary.
Claim 4
Dependent Claim
84 words
The apparatus of claim 1, wherein said guide member has end faces extending in said direction and including a first end face constituting an abutment for one end of each article in the first layer which is overlapped by said first section and a second end face constituting an abutment for one end of each article in the layer which is overlapped by said second section, said end faces being staggered with reference to one another as considered at right angles to said direction.
Claim 5
Dependent Claim
44 words
The apparatus of claim 3, wherein said transferring means comprises a layer-transferring portion for each of said groups and such portions of said transferring means have article-engaging ends which are staggered with reference to one another as considered at right angles to said direction.
Claim 6
Dependent Claim
44 words
The apparatus of claim 4, wherein the extent to which the ends of said portions of said transferring means are staggered with reference to each other matches the extent to which said end faces of said guide member are staggered relative to one another.
Claim 7
Dependent Claim
97 words
The apparatus of claim 1, wherein said conveyor is disposed between said guide member and said groups, said guide means further comprising a second guide member disposed between said groups and said conveyor and having an underside including several sections disposed at different levels and including a first section overlying the articles of transferred first layers, at least while the respective receptacles register with said first group and are transported toward said second group, and a second section which overlies the articles of transferred second layers at least while the respective receptacles register with said second group.
Claim 8
Dependent Claim
37 words
The apparatus of claim 1, wherein said sections of the underside of said guide member have inlet portions flaring upwardly and toward the magazine to facilitate the advancement of articles therealong at right angles to said direction.
Claim 9
Dependent Claim
54 words
The apparatus of claim 1, further comprising an aligning station provided downstream of said groups, as considered in said direction, and including means for aligning the articles of the arrays in successive receptacles during periods of dwell of said conveyor so that the articles of each array leaving said station constitute a parallelepiped block.
Claim 10
Dependent Claim
19 words
The apparatus of claim 8, wherein said locating means includes a stationary portion forming part of said guide means.
Claim 11
Dependent Claim
31 words
The apparatus of claim 9, wherein said conveyor is disposed between said magazine and said guide member and said stationary portion of said locating means forms part of said guide member.
Claim 12
Dependent Claim
19 words
The apparatus of claim 8, wherein said aligning means comprises a mobile portion forming part of said transferring means.
Claim 13
Dependent Claim
35 words
The apparatus of claim 1, wherein said guide member is disposed between said magazine and said conveyor and includes channels for the passage of layers therethrough and into the receptacles registering with the respective groups.
Claim 14
Dependent Claim
19 words
The apparatus of claim 12, wherein said sections of said underside constitute the top boundaries of the respective channels.
Claim 15
Dependent Claim
64 words
The apparatus of claim 1, wherein said magazine includes a third group of ducts disposed downstream of said second group and said underside has a third section overlying the articles of the layer which is transferred from the third group into the receptacle in register with such third group, said second section extending between said second and third groups, as considered in said direction.
Claim 16
Dependent Claim
39 words
The apparatus of claim 1, wherein said first and second groups are arranged to accumulate successive first and second layers wherein the number of articles in the first layers deviates from the number of articles in the second layers.
