general description

The invention relates to a drive for cigarette machines with an electric motor and means for "transmitting the torque, which is a continuously variable Include a gearbox or a gearbox and / or a clutch.

The cigarette machine drive is required to allow the machine to start up slowly and then to the normal working speed of the Maeohine can be switched. The slow approach speed is required so that the operator can observe whether the individual devices the cigarette machine, for example the tobacco feeder, the Be lagband feed, the I * rimapparat, the Printing apparatus and so on, working properly. A cigarette machine drive is known in which an electric drive motor via a belt drive, a multi-stage gearbox and a rigid coupling drives the main shaft of the machine. It is also known in the cigarette machine ^ 'the

Drive motor in connection with an electromagnetic or mechanically manually operated friction clutch »u drive. But here it is not possible »a smaller one Dreheahl than the normal speed over a longer period of time .Start-up or operating time, because the clutch due to the strong heating that occurs in this case quickly spanked. With cigarette machines it is but in some cases you just want to run the machine at a low speed for a long time, for example when starting the machine.

The invention aims to improve the known cigarette machine operation. It is assumed thereby from a drive with an electric motor and means sum transferring the torque, which is a stepless variable transmission or a manual transmission and / or a clutch include, and the invention exists The main idea here is that the coupling is a hydrodynamic fluid coupling is provided. Such couplings are known per se. The use of a fluid coupling allows an almost ideal, i.e. soft, gradual start-up for the requirements of cigarette machine construction of the machine, as it is not with any of the known cigarette machine drives has been achieved so far, with an overload of the drive motor when starting the cigarette machine is completely excluded »In addition,

equips the fluid coupling compared to those known Drives with gradual starting by means of a manually operated friction clutch By varying the contact pressure, the start-up process is automated. The operator with the drive according to the invention only needs to operate a button, and the start-up process of the cigarette machine runs automatically away. In terms of the lack of technical

eft, savvy operators mean this is a weighty privilege. In addition, a drive equipped with a hydrodynamic fluid coupling according to the invention has the advantage, which is essential for practical operation of cigarette machines, that the operator when starting the kasohine can devote himself fully to observing the individual devices of the machine - whether or not they are working properly As is the case with the known outputs of the Pail, a considerable part of the attention must be devoted to the correct actuation of a clutch or a gearbox. When the drive is shut down, it is important that the fluid coupling comes to a standstill quickly, so that the entire characteristic curve of the fluid coupling is passed through again before the drive is set in motion again. According to a further feature, this is achieved in that the

fluid coupling between the gearbox and the main shaft of the cigarette machine in the power transmission is inserted. It is useful here to put the smooth clutch directly on the gearbox output shaft to put.

A secondary to the above-mentioned main inventive idea The idea of the invention consists in “ala drive motor for the cigarette machine a polumeo durable Provide electric motor. This means that you can switch to different modes with the electric motor alone Pole pair numbers the required speed change or speed change can be achieved, so that the gearbox to change the speed, how ee use the well-known cigarette machine drives, is completely saved. Pole-changing electric motors are known as such.

In and of itself, the use of the fluid coupling means in itself and also the use of the pole-changing one Electric motor alone is an essential one Improvement for the cigarette machine. Technically an almost ideal form of drive for the cigarette machine calibrated only when the inventive Main idea and secondary idea are combined with each other, that means that the pole-changing electric motor drives the main shaft of the cigarette machine via a hydrodynamic fluid coupling. A space-saving one Construction arises here when the

Plüssiglceitskupplung is arranged directly on the shaft of the pole-changing electric motor. Instead of the hydrodynamic fluid coupling, another coupling can of course also be used step, so the pole-half electric motor over a clutch, such as a friction clutch, induction clutch or the like, the main shaft of the cigarette machine drive.

In order to bring the cigarette machine to a standstill very quickly in certain cases, after the further embodiment of the drive according to the invention, the power transmission between the electric motor and the main shaft of the cigarette machine is provided with a brake. Advantageously for this purpose is a Spring-loaded, electromagnetically actuated friction brake, which is directly on the main shaft of the cigarette machine is arranged.

In many cases, the cigarette machine is connected directly to a pilter cigarette machine. Served here the operator both machines. Because the control panels of the two machines are usually included are distant from each other, the operation is cumbersome. So this deficiency in cigarette machines with the drive according to the invention is avoided, it is proposed according to a further feature of the invention, the switching devices for starting or stopping

to be placed on two control panels attached to the cigarette machine in separate stalls. One of these switching panel is then attached to that side of the cigarette making machine "on which the Pilterzigarettenmaschine is connected and operated from which the latter, and the other switch panel on the actual operation side of the cigarette machine" After further invention, each of these Schnittabieaus as switching elements a tip button for step-by-step driving on the cigarette machine, at least one start button for driving the cigarette machine in continuous operation and one stop button for stopping the cigarette machine.

So that accidents and operating errors are largely avoided in the drive according to the invention from the outset, the control panels are electrically interlocked with the actuators, and awar derat that after pressing a button on one control panel "a The button operated on the other control panel remains ineffective. To further secure the drive according to the invention, a safety contact is provided according to another feature. This safety contact is actuated depending on the actuation of the closure of the kesser hood of the cigarette machine. This ensures that, as soon as

the knife hood is opened, the contactors drop out, the electric motor is de-energized and the brake is applied. It is thus avoided with certainty that when the operator manipulated with their hands on the dangerous cutter head, another the machine in Can set movement.

Finally, there is another feature of the invention Drive in that a brake release contact is provided. This brake release contact is dependent on actuated by the opening or closing movement of the knife hood of the cigarette machine. By With the brake release contact, it is possible to apply the brake when the drive is at a standstill, i.e. where normally the brake is applied, to release the Hesserträgerwelle to be able to turn by hand when checking or replacing the kettle.
