摘要:
For transporting sensitive articles, in particular cigarette groups, an endless conveyor (19,20) in the form of a toothed belt (21) is provided, carry-along elements (30) for gripping in each case one article being arranged on the same. The carry-along elements (30) are positively controlled such that, when an article is received and/or the movement direction is changed abruptly, an in particular rearwardly directed compensating movement of the carry-along elements takes place.

In the production of cigarette packs, it is necessary to form cigarette groups (10) from a plurality of cigarettes (11) arranged in layers, to be precise by virtue of the cigarette group (10) (or a sub-group) being pushed out of shafts (13) of a cigarette magazine (12) with the aid of push rods (14) which can be moved back and forth. Once a cigarette group (10) has been pushed out, the cigarettes (11) in the magazine shafts (13) drop under their own weight into the pushing-out position. By virtue of the downward movement of the push rods (14) during the return movement into a starting position, the dropping movement of the cigarettes (11) is initiated before the push rods (14) have reached their starting position.
摘要:
Apparatus for sealing thermoplastic sheet materials or for closing packs, such as bags, made of such sheet materials with the aid of heated sealing jaws (22) and mating jaws (25), which accommodate between them the sheet materials and/or folding or closing flaps which are to be connected, the (non-heated) mating jaw (25) having an elastically deformable abutment surface for the sheet materials which are to be sealed, such that any possible elevations produced by a multi-layered design of the folding or closing flaps are compensated for by the elasticity of the abutment surface of the mating jaw. The sealing jaw (22) and/or mating jaw (25) can be moved by a special, oil-free actuating mechanism which, during continuous driving, brings about a standstill phase of the sealing jaw or mating jaw, which can be moved back and forth.
摘要:
Process and apparatus for producing bag packs each having a portion (10) of cut tobacco or the like. For the purpose of producing bag packs with portions (10) of different weights, the portions (10) are compressed in the region of a pressing chamber (14) such that the portion (10) which has to be introduced into the bag (11) is always of the same size--irrespective of the weight. During compaction, the portion (10) is simultaneously formatted so that it corresponds to the interior of the bag (11).
摘要:
The aim is for packs (10) which arrive in close proximity to one another or at irregular intervals from one another to be transported further at precisely predetermined spacings from one another, for example by a removal conveyor (15). For this purpose, the incoming packs (10) are accumulated, an accumulated group (19) being formed in the process, to be precise in the region of an accumulating conveyor (29). The latter transfers individual packs (10) one after the other, in accordance with the timing of the machine, onto an intermediate conveyor (20) which feeds the packs (10) to the removal conveyor (15) at higher speed and forms the desired spacing in the process. The packs (10) remain in the same conveying plane as the precise spacings are formed between them.
摘要:
A valve for controlling flowing media, in particular suction air used in connection with suction heads or the like, in which closing diaphragms (17, 18) made from elastically deformable material are disposed within a valve housing (10) and are subjected to the action of compressed air via actuating lines (14, 15) in the closing or blocking direction, such that when each diaphragm (17, 18) moves into an open position, a subatmospheric pressure is generated on the side ling opposite the closing side.
摘要:
During the production of cigarette packs having an inner wrapper of thin packaging material, the blank (10) of the inner wrapper is provided with impressed lines, namely transverse impressed lines (19, 20) which delimit a base wall (11) which is first contacted by a cigarette group (23) when the latter is wrapped in a U-shaped manner. By virtue of the impressed lines (19, 20), the mechanical load forces exerted on the cigarette group during the U-shaped folding process is reduced. Furthermore, a cigarette conveyor (25) for transferring the cigarette groups (23) is driven in a non-uniform manner, i.e. at reduced speed, when receiving a blank (10), and at a correspondingly greater speed during other conveying operations.
摘要:
Apparatus or gear mechanism for producing linear movements for pushers, carry-along elements and similar elements, in particular during reciprocating movement. The pushers (24, 25) are connected to a gear mechanism (33), in the case of which use is made exclusively of rotating or circulating elements. Each pusher (24, 25) is connected to a lever (37) which is moved by the gear mechanism such that the connection of the lever (37) to the pusher (24, 25) is moved exclusively on a rectilinear path.
摘要:
In the production of filter-tipped cigarettes (25), an apparatus (filter attachment machine) is used, which consists of a main cylinder (10) and a plurality of assigned further cylinders. The elements of the filter-tipped cigarettes (25), specifically a tobacco rod (15) or part-rods (16, 17), filter pieces (21), cigarette units (23), and the filter-tipped cigarettes (25) produced therefrom are transported by the main cylinder (10), with the exception that part-rods (16, 17) displaced at a distance from one another and with a filter piece (21) inserted for the attachment of a wrapping paper (22) are transported and connected to one another outside the main cylinder (10), so that one-piece cigarette units (23) are returned to the main cylinder (10).
摘要:
Process for producing packs made of thin cardboard with an outer wrapper made of shrink-wrap film. Folding tabs of the outer wrapper are connected to one another by full-surface-area heat sealing. The shrink-wrapping process for the outer wrapper may be initiated as a result. In order to ensure a correct form of the outer wrapper, the folding tabs, prior to the full-surface-area sealing operation, are connected to one another by a tack seal, with small, limited sealing surface areas, and are then sealed over the full surface area.
