Cigarette making machines are known from the prior art having the following main assemblies:
A filter tipping machine is an apparatus, or respectively machine, for producing filter cigarettes with a device for receiving tobacco rods of double use length, with a device for cutting these double length tobacco rods into tobacco rods of single length, with a device for inserting double length filter plugs between the tobacco rods of single use length, with a device for connecting the double length filter rods to the two tobacco rods of single use length by wrapping with a sheet of tipping paper that is separated from a supplied strip of tipping paper via a cutting device, with a device for performing a separating cut through the double length filter plugs so that filter cigarettes arise of single use length. With a single track filter tipping machine, a series of tobacco rod-filter plug-tobacco rod groups, arranged consecutively transverse axially, as a single track material stream to a tipping device.
The document EP 1 213 105 B1 for example discloses a filter tipping machine, the disclosure of which is expressly incorporated by reference herein in its entirety.
Further known from the prior art is that with the assembly of cigarettes on a filter tipping machine, with the filter cigarettes produced using a perforation device, perforations of holes are introduced into the wrapping material or wrap strip of the rod-like article. In particular, the perforations are introduced into the wrap strip using laser beams as coherent radiation.
The document DE 27 54 104 A1, the disclosure of which is expressly incorporated by reference herein in its entirety, for example describes a method for controlling the perforation of cigarettes or other rod-like smoking articles.
Furthermore the document DE 27 51 522 A1 describes a device for producing a zone of desired air permeability in a wrap material strip for rod-like articles of the tobacco processing industry on a machine producing the rod-like articles. The disclosure of this document is expressly incorporated by reference herein in its entirety.
Based on this prior art, embodiments of the present invention provide a machine of the tobacco processing industry with a perforation device for rod-like articles and/or for the components thereof. The machine can be easily modified to the spatial conditions in a simple manner.
In accordance with the embodiments, a machine of the tobacco processing industry, in particular a filter tipping machine, can have a machine frame that is designed and configured so conveying arrangements for rod-like articles of the tobacco processing industry and/or the components thereof are provided on the machine frame, and have an external, or respectively separate, laser supply unit for at least one laser device for processing rod-like articles of the tobacco processing industry and/or the components thereof. The laser supply unit has its own separate supply frame that is designed and configured in order to receive one or more supply devices for at least one laser device. The machine frame has an adapter device for a laser device in order to arrange a laser device on or in the machine frame, the supply frame has an adapter device for a laser device in order to arrange a laser device on or in the supply frame, and/or at least one laser device is designed and configured so that the laser device can be arranged or is arranged in co-operation with the adapter device of the machine frame on or in the machine frame, and/or the laser device can be arranged or is arranged in co-operation with the adapter device of the supply frame on or in the supply frame.
Embodiments are based on the idea that a laser device, such as a CO2 laser, for example, can be installed, or respectively adapted without great expenditure on or in corresponding production machines of the tobacco processing industry, such as for example in a filter tipping machine or in a multi-filter making machine, whereby for example a laser device can be inserted in different production machines. Here, for example the laser device with the base housing thereof can be arranged on a laser supply unit, whereby the laser device can be arranged also as a device external to the machine, or respectively a separate device, or as a unit external to the machine for example behind a filter tipping machine. In an alternative, the laser device can also be a part of the production machine so that with the use of the adapter device(s) on or in the machine frame, the housing of the laser device, such as for example the resonator housing of the laser device, is integrated as a component on the machine, such that the devices necessary for operation are provided for the laser device at the external or separate laser supply unit. Hereby, a laser for example which was acquired for an existing filter tipping machine or multi-segment filter making machine, can be used at another, new cigarette making machine, or transferred there, with little expenditure. Thereby, depending on need and application case, additional laser systems can be used successively at several machines of the tobacco processing industry. Thus, costs for expensive laser systems for the perforation of rod-like articles or the components thereof can be advantageously saved. Here, depending on the use case, the laser system can be arranged on the separate laser supply unit or can be arranged for example as a type of attachment directly on the machine frame. Furthermore it is possible to consider respective spatial conditions with the design of the machine and with arrangement of the laser supply unit and the machine.
Hereby a simple, easy to adapt modular design of the machine and the external laser supply unit is attained, so that using the combination and arrangement of the machine frame and the external laser supply unit, the laser device can be adapted to numerous different machines which are designed with an appropriate adapter unit for the laser device.
In a further development is provided that the supply frame is designed and configured in order to receive, preferably in the interior of the supply frame, a control device for the laser device and/or a cooling device for the laser device and/or a voltage supply device for the laser device and/or a compressed air supply device for processing the rod-like articles and/or the components thereof via the laser device.
Advantageously here, in the interior of the supply frame at least one separating wall or several separating walls are provided in order to, preferably completely or respectively substantially completely, separate a device for the laser device selected from the group comprising control device and/or cooling device and/or voltage supply device for the laser device and/or compressed air supply device with respect to another device selected from the same group comprising control device and/or cooling device and/or voltage supply device for the laser device and/or compressed air supply device. Hereby, appropriate spatially separate installation spaces are provided on the supply frame of the external laser supply unit for the control device, the cooling device and for the voltage supply device for operating the laser device and the compressed air supply device for processing, in particular for perforating the rod-like articles and/or the components thereof. In this manner, the different named operating devices for the laser device are arranged separately on or in the supply frame. Hereby the maintenance of the individual operating devices for the laser device is also simplified.
An embodiment of the machine is further directed to the supply frame for the laser device having one, preferably separate, receiving area for at least one laser device or for several, preferably two, laser device. With the use of the adapter device for the laser device, the one laser device can be arranged or is arranged in the receiving area, or using the or several adapter devices of the supply frame, the laser devices can be arranged or are arranged in the receiving area of the supply frame.

For this purpose, in a further embodiment the machine is provided additionally so that the supply frame of the laser supply unit has a housing that can be closed preferably on all sides using flaps and/or doors on the top side and preferably on at least one or all side walls. This results in a housed supply frame, whereby this results in a compact design, if applicable, of the external laser supply unit due to the operating devices received in the supply frame and if applicable with arrangement of a laser device in the supply frame. Furthermore it is attained that no, or only a few dust particles can enter into the interior of the supply frame, whereby the operating devices for the laser device remain clean. For this purpose the frame is designed with flaps and/or doors, whereby this offers simple and direct handling and accessibility from all sides to the operating devices and/or the laser devices on the supply frame. Furthermore, maintenance work on the operating devices and/or the laser device can be performed easily without completely switching off the production machine.
