摘要:
A packaging machine for simultaneously producing cigarette packs in two parallel production tracks. Each track comprises a cigarette magazine, a feeding conveyor, a folding turret, a drying turret and a discharge conveyor which feeds a transverse path common to both tracks. The turrets and conveyors of each track are mounted on opposite sides of a supporting stand with the magazines and conveyors being transversely offset relative the mid-plane of the machine so that the cigarettes of the two tracks are always arranged, fed and discharged in the same orientation of the cigarettes.

In the production of (cigarette) packs made of blanks of thin cardboard, the latter are delivered as blank stacks, normally stacked on pallets. The blank stacks delivered in this or other ways have to be continuously filled into supply magazines of high performance packaging machines. It is therefore necessary, particularly because of the high working speed of the packaging machines, to mechanize and to a large extent automate the transport of the blank stacks. Transporting blank stacks is quite problematic because of accelerations and decelerations occurring at the same time. The basic embodiment of the invention therefore provides a so-called endless pocket conveyor between a feed station and a supply magazine, the pockets of the conveyor holding a blank stack each and not only transporting the blank stacks but also fixing them in proper stack position during transport so that individual stacks can be automatically pushed out of the conveyor pockets and into the magazine. Insofar as further shifts and intermediate transports are necessary, the invention also provides mechanisms which ensure a transport of the blank stacks without endangering the stack arrangement.
摘要:
In packaging machines with an integrated apparatus for the production, storage and conveyance of blanks, the arrangement of the apparatus within the packaging machine is important. It is necessary to ensure that, especially when the reel being, for instance, wound with packaging material is changed, the actual operation of the packaging machine should not be interrupted. For this purpose, a web store (31) is provided, through which a web of material (16) for the production of the blanks (13) and in the form of the reel (17) passes. This web store (31) is located downstream of the reel (17) and upstream of a conveying track (18) for the web of material (16), of a severing station (19) for forming the blanks (13) and of a blank track (26) for feeding the blanks (13) to a folding turret (10) on the rear side (25) of the packaging machine. The web store consists of a storage container (33) having a rectangular cross-section and funnel-shaped run-in and run-out pieces (34, 37 ) with push and draw rollers (36, 39) located upstream and downstream thereof. The web store (31) is formed by zig-zag folding the web of material (16) as a result of kinks or folding lines (32) being disposed at the edges of the blanks (13) (fanfold arrangement of the web of material 16).
摘要:
Known conventional cigarette packs, especially those with a hinge-lid box (10), an inner blank (29) made of tin-foil and possibly an outer wrapping made of plastics foil, are not suitable for disposing of smoked cigarettes (waste-cigarettes 48). It is felt to be undesirable that smoked cigarettes be thrown away individually. This is especially true for "artificial cigarettes" which have recently appeared on the market. In order to achieve an improved waste-disposal, the present cigarette pack, especially as regards its embodiment with a hinge-lid box (10), is provided with a waste compartment (47) for holding waste-cigarettes (48). Park of the inner blank (28), namely its rear-wall (30), forms a partition between the waste compartment (47) and a cigarette compartment (46). Smoked cigarettes are reinserted into the pack through an insert-opening (54).
摘要:
Packaging machines for cigarettes are conventionally equipped with a (cigarette) magazine (11) which receives a stock of cigarettes (10). The lower region of the magazine (11) consists of a plurality of magazine shafts (12) which are divided off from one another by means of shaft walls (13). The cigarettes (10) are extracted at the lower ends of the magazine shafts (12) in groups each corresponding to the content of a cigarette pack, by being pushed out axially. In order to check the cigarettes for defective construction, especially for any gaps (16) in the tobacco in the region of the ends of the cigarettes (10), optoelectrical sensors, especially receivers (17, 18; 30, 31), are arranged in the shaft walls of appropriate thickness. These sensors are directed towards the side of the cigarettes (10) transversely relative to the longitudinal axis of these. Light entering from the end faces of the cigarettes (10) is received by the receivers (17, 18; 30, 31) and evaluated in terms of any gaps (16) in the tobacco. To generate the light, transmitters (19; 32) can be arranged on the end faces of the cigarettes (10) in the front wall (21) and/or rear wall (22) of the magazine (11). The magazine (11) equipped with test members in this way is suitable, in an especially simple and reliable way, for testing and separating out individual or extremely small groups of defective cigarettes.
摘要:
Continuously transported groups (21) of articles (20), in particular packages, are wrapped by means of wrapping with a continuous film web 23 (stretch film) and held together thereby. The article groups (21) are conveyed by an inward conveyor (31) to a winding station (25) having a winding unit (26), and after being wrapped with their wrapping (24) are transported away by an outward conveyor (32). In the region of the winding station (25) the article groups (21) are held, conveyed and in particular fixed in their relative position by a support member (33) which consists of at least one horizontal or vertical support wall. The support wall or support walls are arranged in the region between the articles (20) of one article group (21), in other words in the region of mutually facing surfaces of the articles. As a result, the film web 23 is directly wound around the articles.
摘要:
In order to separate out defective cigarettes (29) in an economical way, cigarettes are tested in the region of magazine shafts (11a, 11b, etc.; 12a, 12b, etc.) of a cigarette magazine (10). The defective cigarettes (29) identified are conveyed beyond a lower main pushing-out plane (22) and are separated out below this. For this purpose, supporting members (carrying webs 32) for the cigarettes are movable up and down at the bottom end of the magazine shafts.
摘要:
To transfer reels (11) to supporting journals (15, 16) of a reel-changing device (12) of a packaging machine (10), the supporting journal (15) is axially displaceable. As a result, the reel can be delivered in the working plane or run-off plane without any transverse displacement and held in the receiving position, while the supporting journal (15, 16) penetrates into a central orifice (42) in the reel (11) as a result of axial displacement.
摘要:
In order to control the pressing-on time of sealing jaws in the sealing of folding tabs consisting of sealable packaging material, a cam element, of which the cam part or cam body 17 has a cam recess 20 of irregular shape, is used. A sensing member (tracer roller 16) is adjustable relative to the cam element as a function of the working speed of an associated packaging machine, so that different regions of the cam element which guarantee an always constant pressing-on time of sealing jaws 12 take effect.
摘要:
An inner wrapping for cigarette shoulder boxes is designed in such a way that, on the one hand, maximum moisture and aroma retention is guaranteed, but on the other hand the design of the inner wrapping is in keeping with processing by machine and favorable handling. The upper wall of the inner wrapping (25) is provided with an extraction orifice (28) which leads up to one of the ends of the cigarettes (24) and which is covered by a closing flap (35) which in the closed position covers the edge regions of the orifice.
