Problems solved by technology

This situation makes the leaf spring itself expensive
Another disadvantage of this solution is that the leaf spring itself must have specific properties, since it is part of the monitoring device, so that the described solution basically cannot be used for all types of leaf springs
In addition, it is also possible to achieve the desired vib...

Embodiment Construction

[0016] exist figure 1 A partial view of a machine used to produce tobacco products, such as cigarettes, can be seen in . The cutting device of the machine is shown in said partial view. In the cutting device, the rod 6 fed in the feed direction 14 is cut into cigarettes of defined length. The cutting device comprises a rotating knife holder 8 . The tool holder has a cardan-shaped tool receptacle 10 in it. The tool 9 is fixed and tensioned in the tool receptacle. Furthermore, the rotary drive 12 is provided with an eccentric rotary bearing 13 . The connecting rod 11 is rotatably mounted on said rotary bearing. When the driving device 12 rotates, the connecting rod 11 is driven to perform repeated reciprocating swinging motions by being supported on the eccentric rotating bearing 13 . Furthermore, a leaf spring 1 is provided. The leaf spring is fixed with a first end 3 to a support 2 fixed to the machine and is connected with a second end 4 to the end 15 of the connecting...

Abstract

The device has a laminated spring (1) with an end (3) firmly clamped at a machine-fixed counter bearing and another end (4) performing motion of the spring. A force sensor (7) and/or a torque sensor is provided between the counter bearing and the clamped end and/or between the two ends of the spring with a part of a machine for manufacturing tobacco products. The spring directly or indirectly lies above a contact surface (3a) at the force sensor. The force sensor (7) comprises a support (5) in which the clamped end of the laminated spring is non-displaceably accommodated.

Description

technical field [0001] The invention relates to a device for monitoring a one-sided fixed tension (eingespannt) leaf spring in a machine for the production of tobacco products having the features of the preamble of claim 1 . Background technique [0002] In machines for the production of tobacco products, leaf springs tensioned on one side are used for purposeful adjustment of the vibration retention and movement characteristics of specific components. Such components are, for example, tubes in the region of the cutting device for guiding the product conveyed in rod form, or vibrating screens for the homogenization of the tobacco. The leaf spring is fixedly tensioned with a first end on a support fixed to the machine and is connected with a second end to the moving part. The leaf springs are subjected to high-frequency movements during machine operation and must be replaced after a certain operating time as wear parts. Tobacco products in the sense of the present invention...
